Abstract Let Fn be the nth Fibonacci number and let Ln be the nth Lucas number. The order of appearance z(n) of a natural number n is defined as the smallest natural number k such that n divides Fk. For instance, z(Fn) = n = z(Ln)/2 for all n > 2. In this paper, among other things, we prove that for all positive integers n ≡ 0,8 (mod 12).

Full textAbstract:
The aim of this research was to estimate the base temperature for the appearance of fruits at harvest point in the strawberry and to propose a concept to represent the time required for the appearance of fruits in consecutive harvests. The experiment was conducted in 2021 in four seedling transplanting seasons: May (season 1), June (season 2), July (season 3) and August (season 4) of two cultivars: Fronteras and Merced. Twenty-four consecutive fruit harvests were carried out from September 9, 2021, to December 1, 2021, when the number, length (cm), diameter (mm), and fresh weight of the fruits (g) were evaluated. The base temperature for the fruit emission of the strawberry was calculated using the method of the smallest mean square error. Carpochron was estimated at each season and for each cultivar, obtaining a simple linear regression between the number of fruits and the accumulated thermal sum (ºC day) and the number of days after transplanting (DAT), using as base temperature the one estimated in this work. The base temperature for the appearance of consecutive fruits at the harvest point in the strawberry is 11ºC. Carpochron increases with the delay of the transplanting season and the values ranged from 81.97ºC fruit day to 144.93ºC fruit day for cultivars Merced and Fronteras.

Full textAbstract:
Cellulite is a highly prevalent condition affecting up to 90% of post pubertal females. The most common reasons patients seek cellulite treatment include emotional, psychological, and practical motivations. Laser-assisted liposuction is a minimally invasive procedure able to produce skin and subcutaneous changes. This research was elaborated as a prospective longitudinal study, aiming to estimate the repercussions of laser-assisted liposuction on thigh cellulite aspects and distribution. Consecutive outpatients with preoperative thigh cellulite submitted to laser-assisted liposuction, using the Lipo One Step HD device, were recruited from the senior author's private practice. Preoperative and 3 months following surgery pictures were obtained. These photographs were assessed by two independent plastic surgeons to evaluate thigh cellulite appearance before and after surgery using the Clinician Reported Photonumeric Cellulite Scale (CR-PCS). Twelve patients entered the study. All patients were female and white. The mean age was 42.5 years (SD ± 9.3), and the mean Body Mass Index was 26.7 kg/m2 (SD ± 2.1). The mean CR-PCS preoperative was 3.75, and 3 months following laser-assisted liposuction was 2.53 (p=0.02). We have obtained comprehensive results demonstrating the role of laser-assisted liposuction on thigh cellulite. In addition, the evidence from our research suggests that laser-assisted liposuction reduces thigh cellulite.

Full textAbstract:
In the field of mobile autonomous robots, visual odometry entails the retrieval of a motion transformation between two consecutive poses of the robot by means of a camera sensor solely. A visual odometry provides an essential information for trajectory estimation in problems such as Localization and SLAM (Simultaneous Localization and Mapping). In this work we present a motion estimation based on a single omnidirectional camera. We exploited the maximized horizontal field of view provided by this camera, which allows us to encode large scene information into the same image. The estimation of the motion transformation between two poses is incrementally computed, since only the processing of two consecutive omnidirectional images is required. Particularly, we exploited the versatility of the information gathered by omnidirectional images to perform both an appearance-based and a feature-based method to obtain visual odometry results. We carried out a set of experiments in real indoor environments to test the validity and suitability of both methods. The data used in the experiments consists of a large sets of omnidirectional images captured along the robot's trajectory in three different real scenarios. Experimental results demonstrate the accuracy of the estimations and the capability of both methods to work in real-time.

Abstract Background and study aims Esophageal xanthomas are considered to be rare, and their endoscopic diagnosis has not been fully elucidated. The aim of the present study was to determine the characteristics of the endoscopic appearance of esophageal xanthomas. Patients and methods This was a retrospective study of consecutive patients with histologically diagnosed esophageal xanthomas at a referral cancer center in Japan. The endoscopic appearance, by magnifying or image-enhanced endoscopy, and histological findings of esophageal xanthomas were investigated. Results Seven patients (six men and one woman) were enrolled. All of the patients had a solitary lesion, and the median size was 2 mm (range, 1 – 5 mm). Conventional white-light endoscopy showed the lesions as flat areas with yellowish spots in four cases and slightly elevated yellowish lesions in three cases. Magnifying endoscopy, performed in six patients, revealed the lesions as areas with aggregated minute yellowish spots with tortuous microvessels inside. Magnifying narrow-band imaging contrasted the yellowish spots and microvessels better than white-light endoscopy. In all lesions, histological examination showed that the yellowish spots corresponded to papillae filled with foam cells. The foam cells were strongly immunopositive for CD68, and in all lesions, CD34-positive intrapapillary capillaries surrounded the aggregated foam cells. The different morphologies of the flat and slightly elevated lesions corresponded to different densities of papillae filled with foam cells. Conclusions Magnifying endoscopy revealed minute yellowish spots with tortuous microvessels inside. These correspond well with histological findings and so may be useful in the diagnosis of esophageal xanthomas.

Full textAbstract:
Object The purpose of this study is to analyze the clinical presentation, morphological characteristics, angio-architecture, and outcome of vertebrobasilar dissection (VBD) in the pediatric population. Methods The authors retrospectively reviewed 29 consecutive cases involving children younger than 16 years of age who were diagnosed with symptomatic VBDs. Data were gathered with respect to the patient's age, sex, clinical history, associated underlying disease, and symptoms (headache, vertigo) as well as the location of the dissection and the imaging appearance. Results The patients' mean age was 8.24 years (range 2 months–15 years). There was an overall 3:1 male predominance, although among children older than 8 years, girls and boys were similarly affected. Hemorrhagic dissections occurred in 10 of 29 cases. In nonhemorrhagic dissections, stroke occurred in 16 cases, with the most common presenting symptoms being headaches and vertigo; in the other 3 cases, mass effect due to a chronic dissecting aneurysm was present. In 7 children an underlying vessel wall disease was found. The location of the dissection was extradural in 11 cases and intradural in the remainder. There was no preference with respect to side. The basilar artery was affected in 9 patients. Conclusions The imaging appearance and clinical presentation of symptomatic VBDs in the pediatric population differs from that in adults. Boys are more often affected, especially at younger ages, and hemorrhagic presentation is more common, presumably owing to the fact that the basilar artery is more commonly involved. Depending on the pathogenetic mechanism underlying the dissection, different clinical symptoms will evolve, necessitating individually tailored treatment.

Full textAbstract:
Video-based person re-identification is an important research topic in computer vision that entails associating a pedestrian’s identity with non-overlapping cameras. It suffers from severe temporal appearance misalignment and visual ambiguity problems. We propose a novel self-supervised human semantic parsing approach (SS-HSP) for video-based person re-identification in this work. It employs self-supervised learning to adaptively segment the human body at pixel-level by estimating motion information of each body part between consecutive frames and explores complementary temporal relations for pursuing reinforced appearance and motion representations. Specifically, a semantic segmentation network within SS-HSP is designed, which exploits self-supervised learning by constructing a pretext task of predicting future frames. The network learns precise human semantic parsing together with the motion field of each body part between consecutive frames, which permits the reconstruction of future frames with the aid of several customized loss functions. Local aligned features of body parts are obtained according to the estimated human parsing. Moreover, an aggregation network is proposed to explore the correlation information across video frames for refining the appearance and motion representations. Extensive experiments on two video datasets have demonstrated the effectiveness of the proposed approach.

Objective: To determine the cancer risk in thyroid nodules using ACR TI-RADS. Methods: A retrospective analysis of all thyroid biopsies was performed over a 3-year period (2021 to 2023). Variables including gender, age, history of thyroid cancer or neck irradiation, nodule size and location, TR level, and sonographic features such as punctate echogenic foci (PEF), a very hypoechoic appearance, taller-than-wide shape, and suspected extrathyroidal extension were analyzed. Results: A total of 1140 nodules were assessed in 993 patients, including 740 females (74.5%) and 253 males (25.5%). The mean patient age was 57.1 ± 15.4 years. Variables significantly associated with nodule malignancy included (1) younger age, (2) a prior history of thyroid cancer or neck irradiation, (3) a higher TR level, (4) a taller-than-wide shape in nodules <1 cm, (5) PEF, (6) a very hypoechoic appearance, and (5) suspected extrathyroidal extension (p < 0.05). Gender, nodule location and size were not associated with a higher cancer risk (p > 0.05). Malignancy was found in 40.7% of TR5, 4.8% of TR4, 0.3% of TR3, and 0% of TR1 and 2 nodules. The odds ratios (ORs) for cancer were as follows: TR4 or 5, OR = 19; PEF, OR = 11; a very hypoechoic appearance, OR = 13.3; and suspected extrathyroidal extension, OR = 27.2 (p < 0.01). Conclusions: Higher TR levels, PEF, a very hypoechoic appearance, and suspected extrathyroidal extension are important features for predicting cancer risk. These findings affirm the effectiveness of ACR TI-RADS in nodule risk stratification.

Background: The formation of scars is fairly inevitable after open rhinoplasty and alar base procedures. Oftentimes, patients exhibit insecurities or discomfort at the appearance of these scars. CO2 laser resurfacing has been proposed as an effective treatment to minimize the appearance of surgical scars. Objective: To demonstrate the effectiveness of fractionated CO2 laser in the minimization of the appearance of surgical scars. Methods: Retrospective analysis of a rhinoplasty surgeon’s database as well as blinded grading of 54 consecutive alar wedge scars using Vancouver Scar Scales. Results: No complications were seen with the use of fractionated CO2 lasers as a treatment on rhinoplasty scars. No difference was seen in scar appearance, including scar height, vascularity, pliability, and scar height after one treatment of CO2 laser. Conclusion: A single treatment of fractionated CO2 laser does not improve scars. Multiple sessions of fractionated CO2 laser could be a more effective treatment for the appearance of surgical scars.

ABSTRACT Several strawberry growers have cultivated the same plants for two consecutive cycles aiming a greater economic return after seedling transplant. However, the phenological development and the agronomic potential of second-cycle strawberry have to be estimated. This research was installed to estimate the thermal need, leaf appearance rate, phyllochron and yield of strawberry cultivars in two consecutive crop cycles in the region of the Third Planalto Paranaense. Cultivars Camarosa, Camino Real, Albion, Aromas, Monterrey and San Andreas were evaluated in the first and second growing cycles using completely randomized blocks and four replications. Leaf appearance rate was estimated by linear regression coefficient between the number of leaves and the accumulated thermal sum. Phyllochron was estimated by the inverse of regression coefficient. Aromas was the only cultivar with an increased fruit production in the second cycle. On the contrary, there was a considerable reduction of production for ‘Camino Real’, ‘Albion’, ‘Monterrey’ and ‘San Andreas’ in that same cycle. The highest number and mass of marketable fruits of the second and first cycles were observed for ‘Camarosa’ and ‘Camino Real’, respectively. In the second crop cycle, strawberry cultivars required a lower thermal sum to begin flowering and fruit harvest. The plants presented a higher leaf appearance rate and low phyllochron values.

For the problem that appearance of human will be changed in motion, it is a challenge to those capabilities of tracker, related to adaptation of human appearance. In the paper, an improved Tracking-Learning-Detection algorithm, including short-term-tracking, real-time-detection and online-learning, is proposed. Furthermore, scale-invariant feature is applied to the short-term-tracking to determine the location of target in consecutive frames. The video stream of the PETS2006 database is utilized to evaluate the proposed algorithm. Experiments results demonstrate the effectiveness, especially on the short-term-tracking performance.

Full textAbstract:
Effective multi-object tracking is still challenging due to the trade-off between tracking accuracy and speed. Because the recent multi-object tracking (MOT) methods leverage object appearance and motion models so as to associate detections between consecutive frames, the key for effective multi-object tracking is to reduce the computational complexity of learning both models. To this end, this work proposes global appearance and motion models to discriminate multiple objects instead of learning local object-specific models. In concrete detail, it learns a global appearance model using contrastive learning between object appearances. In addition, we learn a global relation motion model using relative motion learning between objects. Moreover, this paper proposes object constraint learning for improving tracking efficiency. This study considers the discriminability of the models as a constraint, and learns both models when inconsistency with the constraint occurs. Therefore, object constraint learning differs from the conventional online learning for multi-object tracking which updates learnable parameters per frame. This work incorporates global models and object constraint learning into the confidence-based association method, and compare our tracker with the state-of-the-art methods on public available MOT Challenge datasets. As a result, we achieve 64.5% MOTA (multi-object tracking accuracy) and 6.54 Hz tracking speed on the MOT16 test dataset. The comparison results show that our methods can contribute to improve tracking accuracy and tracking speed together.

Full textAbstract:
The appearance model is very effective in tracking multiple persons. The main difficulty in tracking persons is to represent appearance reliably and effectively, especially in the presence of occlusions. In this paper, an effective Attributed Relational Graph (ARG) based tracking algorithm is presented to track multiple persons even under occlusions. The appearance of each person is expressed by an ARG model which not only combines color feature with spatial information but also illustrates the relations among body parts. The similarity of ARG models is computed to build a matching matrix in consecutive frames. Four tracking situations are determined according to the matching matrix. In addition, to track persons under occlusions, probabilistic relaxation labeling in the ARG models of body parts is deduced to label occluded persons optimally. Experimental validation of the proposed tracking method is verified and presented on indoor and outdoor sequences.

ABSTRACT CONTEXT: The most revolutionary concept in rhytidectomy is the role of Sub Muscular Aponeurotic System (SMAS), even if many alternative approaches have been proposed. The main aim of face lift is to bring back the time, preventing the "lifted-face" appearance. SETTINGS AND DESIGN: The authors present their personal experience with different levels of undermining, i.e. subperiosteal forehead lift, subcutaneous midface lift with SMAS plication and platysmal suspension, and discuss the anatomical and biomechanical elements of rhytidectomy. RESULTS: Optimal aesthetic results were achieved by repositioning the neck, face and forehead tissues in a global and harmonious fashion, without distorting face characteristics and disguising surgery trails as much as possible. CONCLUSIONS: Different levels of undermining can give good and stable aesthetic results minimizing the risks and preventing face distortion.

Full textAbstract:
Tracking-by-detection methods have been widely studied with promising results. These methods usually train a classifier or a pool of classifiers in an online manner and use previous tracking results to generate a new training set for object appearance and update the current model to predict the object location in subsequent frames. However, the updating process may easily cause drifting in terms of appearance variation and occlusion. The previous methods for updating the classifier(s) decided whether or not to update the classifier(s) by a fixed learning rate parameter in all scenarios. The learning rate parameter has a great influence on the tracker’s performance and should be dynamically adjusted according to the change of scene during tracking. In this paper, we propose a novel method to model the time-varying appearance of an object that takes appearance variation and occlusion of local patches into consideration. In contrast with the existing methods, the learning rate for updating classifier ensembles adaptively is adjusted by estimating the appearance variation with sparse optical flow and the possible occlusion of the object between consecutive frames. Experiments and evaluations on some challenging video sequences have been done and the results demonstrate that the proposed method is more robust against appearance variation and occlusion than those state-of-the-art approaches.

Describing the dynamic textures has attracted growing attention in the field of computer vision and pattern recognition. In this paper, a novel approach for recognizing dynamic textures, namely, high order volumetric directional pattern (HOVDP), is proposed. It is an extension of the volumetric directional pattern (VDP) which extracts and fuses the temporal information (dynamic features) from three consecutive frames. HOVDP combines the movement and appearance features together considering the nth order volumetric directional variation patterns of all neighboring pixels from three consecutive frames. In experiments with two challenging video face databases, YouTube Celebrities and Honda/UCSD, HOVDP clearly outperformed a set of state-of-the-art approaches.

In this paper, we proposed an object tracking algorithm in real time implementation of moving object tracking system using Field programmable gate array (FPGA). Object tracking is considered as a binary classification problem and one of the approaches to this problem is that to extract appropriate features from the appearance of the object based on partial least square (PLS) analysis method, which is a low dimension reduction technique in the subspace. In this method, the adaptive appearance model integrated with PLS analysis is used for continuous update of the appearance change of the target over time. For robust and efficient tracking, particle filtering is used in between every two consecutive frames of the video. This has implemented using Cadence and Virtuoso software integrated environment with MATLAB. The experimental results are performed on challenging video sequences to show the performance of the proposed tracking algorithm using FPGA in real time.

The patient was referred for prenatal diagnosis due to the sonographic finding of a polymalformed male fetus, and an amniocentesis was performed before termination of pregnancy. The pathological study of the placenta did not show morphological alterations. In her next pregnancy, sonographic examination disclosed a missed abortion with a visible embryo, and a chorionic villi sample was obtained for cytogenetic analysis before evacuation. Macroscopic examination of the villi sample did not reveal molar vesicular appearance. QF-PCR and cytogenetic analyses were performed on amniotic fluid (first pregnancy) and chorionic villi samples (second pregnancy). A 69,XXY and 92,XXXY karyotype was found, respectively. QF-PCR results disclosed 2 maternal and 1 paternal alleles in the first pregnancy (digynic triploidy), and double maternal and double paternal contribution to the tetraploid pregnancy. Among the few reported cases of 92,XXXY tetraploidy, those associated with partial moles show a PPPM genotype (3 paternal and 1 maternal alleles), and the only case with a PPMM genotype was found in a spontaneously aborted fetus similar to our case. We are not aware of other cases with combination of a digynic triploid pregnancy and a tetraploid pregnancy with a PPMM contribution. Our case adds evidence to the influence of the balance between paternal and maternal genomic doses on the phenotype.

Full textAbstract:
Nowadays, there has been a significant rise in the consumption of kefir, a functional beverage touted for its perceived health benefits. To offer a high-quality beverage to consumers, it is imperative to scrutinize and fine-tune the fermentation process. This study seeks to investigate the impact of fermentation time and the number of subcultures on the physicochemical, microbiological, and volatile composition, as well as the visual appearance, of kefir beverages obtained from four consecutive 24- or 48-h batch subcultures. All fermented beverages exhibited low lactose, ethanol and acids levels, with counts of viable probiotic lactic acid bacteria and yeast exceeding 106 colony forming units/mL. The four kefir beverages from the 48-h batch subcultures notably showed the lowest total concentrations of volatile compounds, likely due to overfermentation and over-acidification of the beverages. This caused the separation of the whey and curd, along with the formation of large gas bubbles, negatively affecting the visual appearance of the products. These findings emphasize the importance of fine-tuning the fermentation process to ensure the production of high-quality kefir beverages that align with consumer preferences. The four beverages from the 24-h batch subcultures exhibited high microbiological and physicochemical stability during storage at 4 °C for 28 days.

FXIIIA appeared as early as the fifth gestational week in yolk sac samples in stellate-shaped cells. Nonparenchymal cells in liver samples showed intense labeling for FXIIIA from the sixth week of gestation. The relative amount of FXIIIA-containing cells rapidly diminished up to the 13th gestational week. When characterized, the majority of these cells proved to be KiM7- positive macrophages, while GPIb (CD42b)-labeled cells accounted for less than 10% of FXIIIA-positive cells. Liver cells did not show any staining for FXIIIA in first trimester samples. The earliest liver specimen showing FXIIIA was at the 20th week, when FXIIIA appeared in some liver cells, particularly in those surrounding the central veins. In bone marrow smears, FXIIIA-positive cells started to appear at week 10 in the clavicles and increased in number in subsequent stages of development. Intracellular FXIIIA was distributed between GPIb-, RFD7-, and KiM7-positive cells. The results indicate that, apart from liver cells, at least three different cell populations (KiM7+ RFD7+ GPIb-, KiM7- RFD7- GPIb-, and KiM7- RFD7- GPIb+) contain FXIIIA in the early phase of human development. We conclude that FXIIIA appears very early during human development and is detectable in both extra- and intraembryonic hematopoietic organs. Intracellular FXIIIA in early human development is distributed between different macrophages and megakaryocytes, and by week 20, it appears in liver cells as well.

Full textAbstract:
In form tapping, the generation of unfinished thread forms results in the appearance of split crests. An experimental technique is developed to study the nature of split crest formation. Custom tools are modeled after tap tooth geometry to perform the forming process in a vertical milling machine. Single-tooth experiments replicate the initial deformation stages and determine the tap geometry and tapping process parameters that significantly affect ridge size and shape. This method is then expanded to consider two axially consecutive tap teeth and the interaction of consecutive ridges to create the final thread form. It is found that certain tap geometrical characteristics are important to the final thread form and, therefore, determine the size and shape of the resulting split crest.

Full textAbstract:
Sonographic evaluation for the presence of hypoechoic hepatic lesions without halo was carried out in 365 consecutive patients with echogenic livers. In 115 patients (31 %) such lesions could be demonstrated. Computed tomography of the liver was performed in 52 of these patients, a long term sonographic follow-up in 76, and a biopsy in 3 cases. In 103 patients the hypoechoic lesions were due to sonographic pseudolesions (PL's), probably representing normal liver tissue in otherwise diffusely fatty infiltrated livers. The PL's showed characteristic sonographic appearances such as a missing mass effect, a ‘landscape’-like configuration with angulated margins and slender extensions of hypoechoic tissue. The PL's were located below the capsule, near the gallbladder (41%), and ventral to the portal vein (37%). In 75 per cent they occurred in a liver with considerably increased echogenicity. In 12 patients hypoechoic lesions were caused by circumscribed malignant or infectious involvement of the liver. They could be discriminated from PL's by their mass-like appearance in 8 subjects. In 4 of these 12 cases the foci were of PL-typical appearance, but not of PL-typical location. In the light of these results and of recently published reports a rational diagnostic approach to hypoechoic lesions without halo in echogenic livers varies, depending on such factors as known primary malignancy or site of the lesion.

Full textAbstract:
Abstract Background Two procedures that have demonstrated collagen-stimulating properties and improvements in skin laxity in a variety of aesthetic indications are microfocused ultrasound with visualization (MFU-V) and injection with calcium hydroxylapatite (CaHA). Objectives By treating skin laxity with a combination of these therapies, it was hypothesized that our patients would experience improved appearance and quality of life as measured by the BODY-Q. Methods A total of 60 consecutive female patients aged 30 to 60 years with body mass index less than 28 kg/m2 who expressed interest in treatment for skin laxity affecting the outer thighs completed selected scales (Body Image, Appraisal of Excess Skin, Satisfaction with Hips and Outer Thighs, and Appearance-Related Psychosocial Distress) from the BODY-Q within 1 week of treatment. At the time of treatment, MFU-V was directed to the outer thighs (150 lines at focal depths of 3.0 and 4.5 mm per outer thigh). Immediately following MFU-V, patients received treatment with CaHA injected into the subdermis (1.5 mL diluted 1:1 with 1.5 mL of 2% lidocaine solution per outer thigh). At 90 days posttreatment, these patients repeated the BODY-Q. Results At 90 days posttreatment, with 100% follow-up among the 60 consecutive female patients treated, scores from the BODY-Q scales showed statistically significant improvement (P &lt; 0.01). Conclusions Following treatment of skin laxity on the outer thighs with a combination of MFU-V and CaHA, our patients reported a statistically significant improvement in appearance and quality of life at 90 days posttreatment. This protocol may be applicable to other areas of the body. Level of Evidence: 4

The site of the first detectable recurrence was recorded in 17 consecutive stage II–IV ovarian carcinoma patients who, after a negative second-look laparotomy, received intraperitoneal chemotherapy with cisplatin and thiosulfate kidney protection. Although the progression-free interval and survival were favorable, 11 patients eventually had a recurrence and in six (54.5%) of these it was extraperitoneal. Brain metastases were detected in three patients. The appearance of extraperitoneal metastases is not always ominous.

Full textAbstract:
The rise of video-prediction algorithms has largely promoted the development of anomaly detection in video surveillance for smart cities and public security. However, most current methods relied on single-scale information to extract appearance (spatial) features and lacked motion (temporal) continuity between video frames. This can cause a loss of partial spatiotemporal information that has great potential to predict future frames, affecting the accuracy of abnormality detection. Thus, we propose a novel prediction network to improve the performance of anomaly detection. Due to the objects of various scales in each video, we use different receptive fields to extract detailed appearance features by the hybrid dilated convolution (HDC) module. Meanwhile, the deeper bidirectional convolutional long short-term memory (DB-ConvLSTM) module can remember the motion information between consecutive frames. Furthermore, we use RGB difference loss to replace optical flow loss as temporal constraint, which greatly reduces the time for optical flow extraction. Compared with the state-of-the-art methods in the anomaly-detection task, experiments prove that our method can more accurately detect abnormalities in various video surveillance scenes.

Full textAbstract:
The article discusses the notion of political correctness and its impact on the decision-making in interpreting from Russian into English in the sphere of politics. The correlation between the notions of political correctness and adequacy of translation is analyzed. Translations of V. Putin’s and S. Lavrov’s speeches and interviews are studied in terms of strategies and techniques employed by the interpreters for the sake of political correctness. Adequacy of translation is also assessed. Conclusions are drawn stating direct dependency of interpreters’ choices on the type of potential discrimination and on the communicative situation requirements. In case of potential discrimination based on gender, race, age, religion, health, appearance, sexual orientation or social status, the political correctness requirements normally do not come into conflict with the communicative situation requirements, so the interpreters use the corresponding English euphemistic equivalents or resort to transformations, mainly generalization. Nevertheless, when political correctness is aligned with political or economic issues, adequacy of translation tends to require direct naming of things, with political correctness waived. This allows to raise the question whether euphemization related to the description of a state’s outer policy or its economic consequences should be part of the sphere of political correctness.

Abstract The importance of cerebral ischemia produced by carotid clamping during carotid endarterectomy remains controversial. In an effort to determine the importance of cerebral ischemia during carotid endarterectomy. 369 patients undergoing 431 consecutive carotid endarterectomies were studied by Xenon-133 (133Xe) clearance and electroencephalogram (EEG) monitoring. None of the patients was shunted during the procedures. The severity of ischemia as indicated by 133 Xe clearance from the ipsilateral hemisphere during 20 to 30 minutes of carotid occlusion did not predict the appearance of complications in this group of patients (x2 = 1.417: P = 0.841). There was a highly significant relationship between the depth of cerebral ischemia as demonstrated by 133Xe clearance and the appearance of abnormalities on the EEG (x2 = 42.043, P &lt; 0.0001). In the subgroup of patients developing abnormalities as shown by EEG. there was a negative correlation (x2 = 17.495; P &lt; 0.002) between reduction in blood flow and the appearance of complications, in that the higher the blood flow during occlusion the more likely the patient developing EEG changes would develop complications.

Full textAbstract:
Purpose: To report an unusual fundus autofluorescence aspect in a patient with suspected hydroxychloroquine retinal toxicity. Method: Case report of an unusual presentation of a patient treated for 9 consecutive years with a therapeutically recommended dose of hydroxychloroquine. Result: We report the case of a 53-year-old Caucasian female treated with 400 mg hydroxychloroquine for rheumatoid arthritis over 9 years, currently on methotrexate and folinic acid, who stopped treatment 3 years ago. The cumulative dose is estimated at 1.314 kg. She recently noticed a reduction of vision in both eyes to 0.34 logMAR, with colour vision problems and major distortion in central vision. Fundus autofluorescence revealed minimal foveal pigmentary changes and more pronounced changes in the retina elsewhere. Foveal changes were confirmed by optical coherence tomography in both eyes. The patient did not report any colour perception difficulties or night vision problems and has no family history of any eye condition. Her visual field tested by an optician was full, with some central changes. Conclusion: Retinal toxicity from hydroxychloroquine can present in a different aspect than the commonly known retinal toxicity, and it happens even after years of cessation of the drug. The role of cumulative dose in toxicity is supported in this paper.

Intraoperative neurophysiologic monitoring during brain tumor surgery should acquire a baseline data as soon as possible. However, motor unit potentials (MEP) in our case showed baseline data could not be acquired in the early stage of surgery, but consecutive trials had abrupt appearance of MEP just after dura opening. This case shows the acquisition of baseline MEP during brain tumor surgery should not be given up until the dura is open especially in a state of raised intracranial pressure.

Purpose. To study the clinical significance of the Graves’ orbitopathy-specific quality of life (GO-QOL) questionnaire in mainland Chinese patients. Methods. A cross-sectional study was performed at the Ophthalmology Department of the Sun Yat-sen Memorial Hospital from April 2017 to April 2018. Eighty-eight consecutive Graves’ orbitopathy (GO) patients completed the two subscales of the GO-QOL questionnaire: visual functioning and appearance. The disease severity of GO was measured by the European Group on Graves’ Orbitopathy (EUGOGO) classification, and clinical activity was evaluated by the clinical activity score (CAS). Results. The mean scores of GO-QOL questionnaire for the visual functioning and appearance subscales were 68.4 ± 31.2 and 62.0 ± 27.4, respectively. Lower QOL scores for the visual functioning subscale were significantly correlated with disease severity, the CAS and diplopia (all p<0.05). Lower QOL scores for appearance were significantly correlated with the CAS (p<0.05). Although no correlation was found between the appearance subscale scores and disease severity (p=0.407), a downward trend in the appearance subscale scores as the severity of GO increased from mild to sight-threatening GO was found. Conclusion. A strong correlation between disease severity and clinical activity has been shown in the GO-QOL questionnaire, suggested by the EUGOGO. The GO-QOL questionnaire is a simple and effective appraisal instrument in the evaluation of health-related QOL in the mainland Chinese patients with GO.

Full textAbstract:
Abnormalities of dental development and anatomy may suggest the presence of congenital or acquired anomalies. The detection of abnormalities, therefore, is an important skill for radiologists to achieve. Knowledge of dental embryology and an understanding of the radiologic appearances of teeth at various stages of maturation are required for the appreciation of abnormal dental development. While many tooth abnormalities are well-depicted on dedicated dental radiographs, the first encounter with a dental anomaly may be by a radiologist on a computed tomographic (CT) or magnetic resonance (MR) exam performed for other reasons. This article depicts normal dental anatomy and development, describing the appearance of the neonatal dentition on CT and MRI, the modalities most often encountered by clinical radiologists. The radiology and dental literature are reviewed, and key concepts are illustrated with supplemental cases from our institution. The value of knowledge of dental development is investigated using the analysis of consecutive MR brain examinations. Finally, the anatomical principles are applied to the diagnosis of odontogenic infection on CT. Through analysis of the literature and case data, the contrast of dental pathology with normal anatomy and development facilitates the detection and characterization of both congenital and acquired dental disease.

Full textAbstract:
Consecutive monoculture of Rehmannia glutinosa in the same field leads to a severe decline in both quality and yield of tuberous roots, the most useful part in traditional Chinese medicine. Fungi are an important and diverse group of microorganisms in the soil ecosystem and play crucial roles in soil health. In this study, high-throughput pyrosequencing of internal transcribed spacer 2 ribosomal DNA amplicons was applied to gain insight into how consecutive monoculture practice influence and stimulate R. glutinosa rhizosphere and bulk soil fungal communities. The results from nonmetric multidimensional scaling ordination and clustering analysis revealed distinctive differences between rhizosphere and bulk soil fungal communities. However, longer-term monocultured bulk soils were more similar to the rhizosphere soils in comparison with the shorter-term monocultured bulk soils. Moreover, consecutive monoculture caused a gradual shift in the composition and structure of the soil fungal community. The cultivation of this plant led to the appearance of some exclusive operational taxonomic units in rhizosphere or bulk soils that were assigned to the genera Fusarium, Rhizoctonia, and so on. Furthermore, the sum of the relative abundance of species of Fusarium, Cylindrocarpon, and Gibberella (belonging to the family Nectriaceae); Rhizoctonia, Thanatephorus, and Ceratobasidium (belonging to the family Ceratobasidiaceae); and Lectera and Plectosporium (belonging to the family Plectosphaerellaceae) was significantly higher in consecutively monocultured (CM) than in newly planted (NP) soil in both rhizosphere and bulk soils. In particular, Fusarium abundance was significantly higher in CM than in NP in the rhizosphere, and higher in rhizosphere soils than in bulk soils for each treatment. A pathogenicity test showed that both Fusarium strains isolated were pathogenic to R. glutinosa seedlings. In addition, the culture filtrate and mycotoxins produced by Fusarium oxysporum significantly repressed the growth of the antagonistic bacterium, Pseudomonas aeruginosa. In conclusion, consecutive monoculture of R. glutinosa restructured the fungal communities in both rhizosphere and bulk soils but bulk effects developed more slowly over time in comparison with rhizosphere effects. Furthermore, microbial interactions might lead to a reduction in the abundance of beneficial microbes.

AbstractPrimary tumors of the heart are rare. The majority of them are benign, the left atrial myxoma being the most frequent one. Clinical appearance varies from unapparent to life-threatening complications such as stroke, acute heart failure, or even sudden death. Diagnosis and consecutive surgical treatment strongly depend on the clinical symptoms, but their extent does not correlate with the risk for serious complications. Therefore, patients with variable clinical presentation can be especially endangered. Consequent diagnostic and immediate operative therapy is essential.

General concepts related to synchronic translation illustrate that it is very broad area of oral translation. In the following article, we are going to discuss general information dealing with this branch of translation, in which we look into the emergence of simultaneous interpretation as well as considering the differences between the types of oral translation. And we try to highlight theoretical basis of simultaneous interpretation which were presented by the scientists who even currently work as professional interpreters. Now that the huge demand for simultaneous interpretation is increasing, it is incredibly essential to gain fundamental background on the synchronic translational methods, techniques, ways and peculiarities. In this article, we also try to look back into the history and developmental way of the synchronic translation. Besides that, we get acquainted with what kind of factors affected to the appearance of this type of oral translation. In this line we also spot the main differences of simultaneous and consecutive interpretation.

Objective: The purposes of this study were to investigate self-reported social experience in 10-year-old children born with a cleft lip and/or palate and to gain a better understanding of variables implicated in psychosocial resilience. Design: Cross-sectional study of 10-year-old children from five consecutive birth cohorts, born from 1992 to 1997. Participants: A total of 268 children treated by the Oslo cleft team (Norway) participated in the study. The children's cleft conditions included cleft lip and palate, cleft lip alveolus, cleft palate, and submucous cleft palate. Outcome Measures: Psychosocial resilience was measured with the Child Experience Questionnaire (CEQ). Other variables were obtained during a clinical interview with the child. Cognitive, emotional, and psychosocial functioning was measured with the Personality Inventory for Children (PIC). Satisfaction with appearance was assessed through the use of the Satisfaction with Appearance Scales (SWA). Informants were both children and parents. Results: Cleft types differed significantly with respect to subtype and frequency of additional difficulties. Psychosocial resilience was associated with adequate emotional functioning, high satisfaction with appearance, and a lower frequency of reported teasing. Child characteristics such as visibility of cleft, gender, and additional diagnosis did not contribute to explain psychosocial resilience. Conclusions: Results reported here emphasise the importance of assessing the child's subjective report of satisfaction with appearance and psychosocial experience.

Background: Pain and scar are the two important criteria bothering the patients after thyroid surgeries. Incisions on the neck when heal has to be scarless or minimum scar. Hence, we opted to study for the better methods of skin closure to obtain less pain and less scar. Aim: The study compared subcuticular suture, metal clips, and steristrips for wound closure after thyroid surgery based on the postoperative pain assessment, neck mobility, and cosmetic appearance. Materials and Methods: The prospective study which includes a consecutive series of 93 (n = 93). Patients undergoing thyroidectomy who were randomized to have their wound’s closed by subcuticular sutures or steristrips or staples. The randomization code was generated using a table of random numbers, and the sealed envelope was opened at the end of each operation. Results: In this study, wound closure by steristrips had less postoperative pain followed by subcuticular suture and metal clips. In our study, neck mobility after thyroid surgery, steristrips had acceptable neck mobility compared to subcuticular suture and metalclips. In our study, cosmetic appearance after thyroid surgery wound closure with steristrips had excellent scar appearance followed by subcuticular suture and metal clips. Conclusion: In the final analysis, the choice of wound closure materials will depend on the surgeon’s preference. However, this study showed that steristrips had less pain, acceptable neck mobility, excellent scar appearance followed by thyroidectomy surgery.

Few reports of the Western countries have investigated the value of palliative surgery for stomach cancer. The aim of this study was to evaluate the results of palliative surgery in a large series of patients affected by gastric carcinoma, consecutively treated by the same surgical team. The hospital records of 305 patients affected by gastric cancer who did not undergo surgical treatment or who underwent a palliative surgical procedure at our unit between 1981 and 1995 were reviewed. Univariate and multivariate analyses were used to calculate the 5-year survival probabilities with respect to the following variables: demographic data, tumor location and gross appearance, spread of the disease, histological type according to P. Lauren, and type of treatment. Multivariate logistic regression analysis showed that resectional surgery and tumor spread limited to local sites were independently associated with better survival. The study indicates that even though there are host-related factors that govern survival in far-advanced stomach cancer, the type of surgery can have a significant effect on prognosis; resectional surgery should be undertaken whenever possible in such patients.

Objective: Rhinoplasty in patients with complete unilateral cleft lip and palate (UCLP) is challenging, and the surgical outcome of the nose is complicated to evaluate. The aim of this study was to assess the nasolabial appearance of patients with UCLP compared with a control group. Design: Cross-sectional study. Setting: Riga Cleft Lip and Palate Centre, Latvia. Participants: All consecutive 35 patients born between 1994 and 2004 with nonsyndromic complete UCLP were included. Of 35 patients, 29 came for checkup; the mean age was 14.7 years (range 10-18). In the control group, 35 noncleft participants at 10 years of age were included. Interventions: Nasolabial appearance was evaluated from 3-dimensional images using a 3-dimensional stereo-photogrammetric camera setup (3dMDface System), the results being analysed statistically. Results: In UCLP group, a statistically significant difference between cleft and noncleft side was found only in alar wing length ( P < .05). The difference of nasolabial anthropometric distances in the control group between the left and right side was not significant. The difference between the UCLP group and the control group was significant in all anthropometric distances except the lateral lip length to cupid’s bow. Conclusions: The nasolabial appearance with acceptable symmetry after cleft lip and reconstructive surgery of the nose was achieved. Symmetry of the nasolabial appearance in patients with UCLP differed from those in the control group. The 3D photographs with a proposed set of anthropometric landmarks for evaluation of nasolabial appearance seems to be a convenient, accurate, and noninvasive way to follow and evaluate patients after surgery.

Full textAbstract:
The appearance of carbonic anhydrase isoenzymes in rat liver and skeletal muscle during fetal and postnatal development was studied with immunohistochemistry. In the 12-day fetus the early strong expression of CA I in hepatocytes was partially replaced by the expression of CA II and CA III during late prenatal development. In the 20-day fetus the staining intensity of CA III was equal to that of a mature female rat. In the male, the staining intensity in hepatocytes clearly increased during sexual maturation. Immunoelectron microscopy showed diffuse cytoplasmic and nucleoplasmic staining of CA III in hepatocytes. The time-dependent expression of the isoenzymes in hepatocytes may reflect a different metabolic function of these structurally closely related isoenzymes. In skeletal muscle, CA III was the only isoenzyme detected during development. In late prenatal and early postnatal stages all muscle fibers contained about equal amounts of CA III. The differentiation of the muscle according to the expression of CA III occurred during the first 3 postnatal weeks.

ABSTRACT To define the extent of sequence conservation in human immunodeficiency virus type 1 (HIV-1) reverse transcriptase (RT) in vivo, the first 320 amino acids of RT obtained from 2,236 plasma-derived samples from a well-defined cohort of 1,704 HIV-1-infected individuals (457 drug naïve and 1,247 drug treated) were analyzed and examined in structural terms. In naïve patients, 233 out of these 320 residues (73%) were conserved (<1% variability). The majority of invariant amino acids clustered into defined regions comprising between 5 and 29 consecutive residues. Of the nine longest invariant regions identified, some contained residues and domains critical for enzyme stability and function. In patients treated with RT inhibitors, despite profound drug pressure and the appearance of mutations primarily associated with resistance, 202 amino acids (63%) remained highly conserved and appeared mostly distributed in regions of variable length. This finding suggests that participation of consecutive residues in structural domains is strictly required for cooperative functions and sustainability of HIV-1 RT activity. Besides confirming the conservation of amino acids that are already known to be important for catalytic activity, stability of the heterodimer interface, and/or primer/template binding, the other 62 new invariable residues are now identified and mapped onto the three-dimensional structure of the enzyme. This new knowledge could be of help in the structure-based design of novel resistance-evading drugs.

How to effectively exploit spatio-temporal information is crucial to capture target appearance changes in visual tracking. However, most deep learning-based trackers mainly focus on designing a complicated appearance model or template updating strategy, while lacking the exploitation of context between consecutive frames and thus entailing the when-and-how-to-update dilemma. To address these issues, we propose a novel explicit visual prompts framework for visual tracking, dubbed EVPTrack. Specifically, we utilize spatio-temporal tokens to propagate information between consecutive frames without focusing on updating templates. As a result, we cannot only alleviate the challenge of when-to-update, but also avoid the hyper-parameters associated with updating strategies. Then, we utilize the spatio-temporal tokens to generate explicit visual prompts that facilitate inference in the current frame. The prompts are fed into a transformer encoder together with the image tokens without additional processing. Consequently, the efficiency of our model is improved by avoiding how-to-update. In addition, we consider multi-scale information as explicit visual prompts, providing multiscale template features to enhance the EVPTrack's ability to handle target scale changes. Extensive experimental results on six benchmarks (i.e., LaSOT, LaSOText, GOT-10k, UAV123, TrackingNet, and TNL2K.) validate that our EVPTrack can achieve competitive performance at a real-time speed by effectively exploiting both spatio-temporal and multi-scale information.

Full textAbstract:
In this paper, we study nonlinear differential equations with Caputo fractional derivatives with respect to other functions and impulses. The main characteristic of the impulses is that the time between two consecutive impulsive moments is defined by random variables. These random variables are independent. As the distribution of these random variables is very important, we consider the Erlang distribution. It generalizes the exponential distribution, which is very appropriate for describing the time between the appearance of two consecutive events. We describe a detailed solution to the studied problem, which is a stochastic process. We define the p-exponential stability of the solutions and obtain sufficient conditions. The study is based on the application of appropriate Lyapunov functions. The obtained sufficient conditions depend not only on the nonlinear function and impulsive functions, but also on the function used in the fractional derivative. The obtained results are illustrated using some examples.
