Full textAbstract:
As system-on-chip (SoC) integration is growing very rapidly, increased circuit densities in SoC have lead a radical increase in test data volume and reduction of this large test data volume is one of the biggest challenges in the testing industry. This paper presents an efficient test independent compression scheme primarily based on the error correcting Hamming codes. The scheme operates on the pre-computed test data without the need of structural information of the circuit under test and thus it is applicable for IP cores in SoC. Test vectors are equally sliced into the size of ‘<em>n’</em> bits. Individual slices are treated as a Hamming codeword consisting of ‘<em>p’</em> parity bits and ‘<em>d’</em> data bits (<em>n = d + p)</em> and validity of each codeword is verified. If a valid slice is encountered<em>’</em> data bits prefixed by ‘<em>1’</em> are written to the compressed file, while for a non-valid slice all ‘<em>n’</em> bits preceded by ‘<em>0’</em> are written to the compressed file. Finally, we apply Huffman coding and RLE in order to improve the compression ratio further The efficiency of the proposed hybrid scheme is verified with the experimental outcomes and comparisons to existing compression methods suitable for testing of IP cores.

Objectives: Computed tomographic (CT) scanning with slices of 1 mm or more has not been sufficient to demonstrate otosclerotic foci in most cases to date. Methods: We investigated the validity of CT scans with a 0.5-mm cubical scan technique, with and without planar reconstruction, and correlated these findings with audiological data. Forty-four temporal bone CT scans from 30 patients with conductive or mixed hearing loss were evaluated. Results: Otosclerotic foci were visualized in 74% of the cases. With reconstruction at the workstation, the sensitivity increased to 85%. Whereas in fenestral otosclerosis a correlation was found between the size of the focus and the air-bone gap, no correlation was seen between the size of the focus and bone conduction thresholds with cochlear involvement. Otosclerotic foci in patients treated with sodium fluoride were smaller than those in patients without treatment. This finding may indicate a beneficial effect of sodium fluoride on otosclerotic growth. Conclusions: High-resolution CT scans are a valid tool that can be used to confirm, localize, and determine the size of clinically suspected otosclerotic foci.

Full textAbstract:
Bi-metallic piping welds are frequently used in light water nuclear reactors to connect ferritic steel pressure vessel nozzles to austenitic stainless steel primary cooling piping systems. An important aspect for the integrity of such welds is the presence of residual stresses. Measurement of these residual stresses presents a considerable challenge because of the component size and because of the material heterogeneity in the weld regions. The specimen investigated here was a thin slice cut from a full-scale bi-metallic piping weld mock-up. A similar mock-up had previously been investigated by neutron diffraction within a European research project called ADIMEW. However, at that time, due to the wall thickness of the pipe, stress and spatial resolution of the measurements were severely restricted. One aim of the present investigations by high energy synchrotron radiation and neutrons used on this thin slice was to determine whether such measurements would render a valid representation of the axial strains and stresses in the uncut large-scale structure. The advantage of the small specimen was, apart from the easier manipulation, the fact that measurement times facilitated a high density of measurements across large parts of the test piece in a reasonable time. Furthermore, the recording of complete diffraction patterns within the accessible diffraction angle range by synchrotron X-ray diffraction permitted mapping the texture variations. The strain and stress results obtained are presented and compared for the neutron and synchrotron X-ray diffraction measurements. A strong variation of the texture pole orientations is observed in the weld regions which could be attributed to individual weld torch passes. The effect of specimen rocking on the scatter of the diffraction data in the butt weld region is assessed during the neutron diffraction measurements.

Purpose: To determine the clinical feasibility of rapid‐sequence phosphorus‐31 magnetic resonance spectroscopy (31P ‐MRS) of the heart with cardiac patients using a 1.5T clinical MR system. Material and Methods: Twenty cardiac patients, i.e. dilated cardiomyopathy (DCM) 13 cases, hypertrophic cardiomyopathy (HCM) 3 cases, hypertensive heart diseases (HHD) 3 cases, and aortic regurgitation (AR) 1 case were examined using rapid cardiac 31P‐MRS. Complete three‐dimensional localization was performed using a two‐dimensional phosphorus chemical‐shift imaging sequence in combination with 30‐mm axial slice‐selective excitation. The rapid‐sequence 31P‐MRS procedure was phase encoded in arrays of 8×8 steps with an average of 4 acquisitions. The total examination time, including proton imaging and shimming, for the rapid cardiac 31P‐MRS procedure, ranged from 10 to 15 min, depending on the heart rate. Student's t test was used to compare creatine phosphate (PCr)/adenosine triphosphate (ATP) ratios from the cardiac patients with those of the control subjects ( n = 13). Results: The myocardial PCr/ATP ratio obtained by rapid 31P‐MRS was significantly lower ( P<0.001) in DCM patients (1.82±0.33, mean±SD), and in patients with global myocardial dysfunction (combined data for 20 patients: 1.89±0.32) than in normal volunteers (2.96±0.59). These results are similar to previous studies. Conclusion: Rapid‐sequence 31P‐MRS may be a valid diagnostic tool for patients with cardiac disease.

Abstract Context.—Creating a tool that assesses professional proficiency in gynecologic cytology is challenging. A valid proficiency test (PT) must reflect practice conditions, evaluate locator and interpretive skills, and discriminate between those practitioners who are competent and those who need more education. The College of American Pathologists Gynecologic Cytology Proficiency Testing Program (PAPPT) was approved to enroll participants in a nationwide PT program in 2006. Objective.—Report results from the 2006 PAPPT program. Design.—Summarize PT results by pass/fail rate, participant type, and slide-set modules. Results.—Nine thousand sixty-nine participants showed initial PT failure rates of 5%, 16%, and 6% for cytotechnologists, primary screening pathologists, and secondary screening pathologist, respectively. The overall initial test failure rate was 6%. After 3 retests, 9029 (99.6%) of the participants were able to achieve compliance with the PT requirement. No participant “tested out”; however, 40 individuals “dropped out” of the testing sequence (8 cytotechnologists, 9 primary screening pathologists, 23 secondary screening pathologists). Initial failure rates by slide-set modules were 6% conventional, 6% ThinPrep, 6% SurePath, and 5% mixture of all 3 slide types. Conclusions.—A total of 99.6% of individuals enrolled in the 2006 PAPPT program achieved satisfactory results. The data confirm that cytotechnologists have higher initial pass rates than pathologists and pathologists who are secondary screeners perform better than those who are primary screeners. There was no difference identified in overall pass rates between the slide-set modules. Further analysis of data should help define the results and ongoing challenges of providing a nationwide federally mandated proficiency testing program in gynecologic cytology.

The use of Arduino-Based floodgates aims to address the issue of flooding. The goal of this research was to create a system that could monitor water levels and control floodgatesUltrasonic sensor was used to measure water level, as the water level becomes the indicator to open and close the floodgates. The ultrasonic sensor is mounted on the dam and measures the distance between the water’s surface and the sensor transmitter. The results of the measurement of the water level are used to control the floodgates. Sensor measurement results are not always valid, given the age of the sensor and the terrain around the dam is quite challenging. The self-check sensor feature is introduced in this study as a way to overcome detection faults in the system, where ultrasonic sensors can perform self-monitoring by relying solely on their neighbours. In general, the process is carried out in four stages, starting from the stage of reading the sensor, the stage transmitting and receiving data from the Arduino, the stage of detecting sensor’s value, the stage of displaying the sensor values. At the stage of displaying the sensor value, there are four water level conditions, normal, waspada, siaga and bahaya. According to the test results, incorporating self-check sensors into the system enables for more efficient Arduino-based sluice control systems, as well as the possibility of detecting malfunctions caused by sensor damage

Abstract Emphysema is visible on computed tomography (CT) as low-density lesions representing the destruction of the pulmonary alveoli. To train a machine learning model on the emphysema extent in CT images, labeled image data is needed. The provision of these labels requires trained readers, who are a limited resource. The purpose of the study was to test the reading time, inter-observer reliability and validity of the multi-reader–multi-split method for acquiring CT image labels from radiologists. The approximately 500 slices of each stack of lung CT images were split into 1-cm chunks, with 17 thin axial slices per chunk. The chunks were randomly distributed to 26 readers, radiologists and radiology residents. Each chunk was given a quick score concerning emphysema type and severity in the left and right lung separately. A cohort of 102 subjects, with varying degrees of visible emphysema in the lung CT images, was selected from the SCAPIS pilot, performed in 2012 in Gothenburg, Sweden. In total, the readers created 9050 labels for 2881 chunks. Image labels were compared with regional annotations already provided at the SCAPIS pilot inclusion. The median reading time per chunk was 15 s. The inter-observer Krippendorff’s alpha was 0.40 and 0.53 for emphysema type and score, respectively, and higher in the apical part than in the basal part of the lungs. The multi-split emphysema scores were generally consistent with regional annotations. In conclusion, the multi-reader–multi-split method provided reasonably valid image labels, with an estimation of the inter-observer reliability.

ABSTRACT <strong>Purpose:</strong> To examine the mediating effect of Customer Relationship Management (CRM) amid Digital Buying Behaviour (DBB) and Risk Factors (RF).<strong> Methods:</strong> The structured questionnaire was adopted to analyse critical factors of DBB, RF and CRM. The instrument was designed and validated with the help of exploratory factor analysis and confirmed the items by confirmatory factor analysis. The model fitness is verified. The reliability of the scale was tested along with CR. The field testing is done to remove ambiguity. The nativity changes were incorporated to align the current study. The responses were collected using convenience sampling method through the e-mail survey and 410 valid responses (digital consumers) considered. The data were collected during August – November 2022. Quantitative approach is used to examine both directions of the considered variables. First, the direct effect of DBB on RF is examined. Secondly, the direct effect of CRM is studied. Further, mediating effect of CRM in relationship amid DBB and RF is established.<strong> Findings:</strong> The DBB is significant and directly connected with RF (b = 0.952, p < .001), CRM is significant and positively allied with RF (b = 0.471, p < .001). DBB is significant and positively related to CRM (b = 0.779, p < 0.001), after removal of mediating variable (CRM), b weight of DBB is reduced from 0.952 to 0.703. Sobel test is steered to confirm the significance of the mediation effect of CRM, test statistic (z= 3.09, p <.001). Thus, CRM act as a partial mediator amid DBB and RF. <strong>Novelty:</strong> The present study integrates DBB, RF and CRM features associated in digital buying in solitary manner unlike sliced approach. The study of CRM role especially in digital buying is a uniqueness of the present research.

Abstract Context.—Learning the characteristics of frozen tissue samples stored in tumor banks for biological studies remains a problem. Objective.—To assess the use of touch imprint cytology on fresh tissue samples as a rapid and reliable method of determining the presence and quantity of neoplastic cells before freezing. Design.—Touch imprint cytology was performed on 259 specimens of operable breast cancer. Touch imprints were prepared from fresh tissue specimens before freezing samples for storage. Each tumor sample was imprinted on a glass slide and stained with hematoxylin-eosin. Tumor cellularity was quantified as negative, poor, moderate, or rich. Results.—A significant correlation was found between samples with a tumor size greater than 2 cm and high tumor cellularity (P = .03; χ2 test). Furthermore, 35% of ductal tumors showed higher tumor cellularity compared with lobular tumors (P &lt; .001; χ2 test). No association was found between lymph node status and tumor grade. When samples for which more than 2 imprints were available were examined, tumor cellularity among imprints of the same sample showed an overall agreement of 0.67 (P &lt; .001; κ statistic). It was also determined that the higher the cellularity, the higher the agreement. Our data also showed concordance of 0.87 (P &lt; .001; κ statistic) between touch imprint cytology imprints and histologic sections from contiguous tumor. Moreover, 11 randomly selected samples underwent DNA extraction, polymerase chain reaction, and sequencing to verify the feasibility of DNA analyses. We found that DNA from touch imprint cytology was amplifiable and suitable for direct sequencing. Conclusions.—Touch imprint cytology may represent an important step in the quality control of tumor cellularity of breast cancer specimens designed to be stored in tumor biobanks and a valid method for assessing the suitability of such tissue for further biomorphologic and biomolecular applications.

BackgroundTo date, there is no validated lupus-specific questionnaire for health-related quality of life (HRQoL) in German language. Regular assessment of health-related quality of life is recommended for monitoring and outcome in current management guidelines [1][2]. Given that about 20% of the EU population are native German speakers, it is therefore essential to validate a Lupus-specific questionnaire in German.ObjectivesThe aim of this study is to present the validity (content, construct, and criterion) and reliability (internal consistency and test-retest) of the German translation of the LupusPro questionnaire, which captures both generic and lupus-specific HRQoL domains.MethodsThe German LupusPRO was professionally translated and then administered to consecutive patients with systemic lupus erythematosus treated at our tertiary centre. At each visit, clinical and laboratory data were collected, including disease activity and damage (SLEDAI-2K resp. SLICC/SDI). Additional questionnaires were used for validity testing, including questionnaires for HRQoL (SF-36v2), fatigue (FACIT), depression (CES-D), sleep (PSQI) and health impairments (IMET).We calculated Cronbach’s alpha to test reliability. An alpha >0.70 is considered acceptable. Test-retest reliability was tested by evaluating the consistency between the LupusPro at two time points (T0 and T1 after 2-3 days). Criterion and construct validity was assessed by comparing the results of the LupusPRO with the generic HRQoL questionnaire, established clinical endpoints (disease activity, disease damage), and the domains of the additional questionnaires. The confirmatory factor analysis was performed with the Lavaan package (Ver. 0.6-9) in R using the relative fit indices, the Tucker-Lewis index (TLI) and the comparative fit index (CFI).Results148 patients with confirmed SLE took part in the study of which 111 participated in the test-retest analysis. About 84% were female with a mean age of 45.5 (SD 12.0) and mean disease duration of 17.7 (SD 9.7) yrs. The mean SLEDAI-2K was 3.1 (SD 3.2) and SLICC/SDI 1.4 (SD 2.1).The LupusPro domain’s internal consistency by Cronbach’s alpha exceeded >0.7 except for the domains lupus symptoms (α=0.64), lupus medication (α=0.59), procreative ability (α=0.58), and coping strategies (α=0.43). The overall test-retest correlation was excellent (ICC=0.94). The correlation of the corresponding LupusPRO and SF-36v2 domains were moderate to strong (ρ=0.54–0.78), whereas correlation with disease activity and damage (SLEDAI-2K and SLICC/SDI) was weak (ρ=-0.23 resp. -0.08). Correlation of the selected LupusPRO domains with the above mentioned other dedicated outcome measure instrument emphasized construct and criterion validity.The results of the confirmatory factor analysis showed good construct validity of the LupusPRO. The observed model fit for the hypothesized item-scale relationships was very good (CFI = 0.98, TLI = 0.98). Items generally had loadings of >0.6 with their respective factor. Exceptions were especially the domain coping strategies where all items loaded <0.4.ConclusionThe GermanLupusPRO is a valid instrument for measuring health-related quality of life. It shows comparable psychometric properties as the original versions. Minor difference in individual domains may be explained by sociocultural factors.References[1]Gordon C et al. doi: 10.1093/rheumatology/kex286.

Objectives The objective of this article is to validate the Lupus Impact Tracker (LIT), a disease-specific patient-reported outcome (PRO) tool, in systemic lupus erythematosus (SLE) patients in a multi-ethnic Australian cohort. Methods Patients attending the Monash Lupus Clinic were asked to complete the LIT, a 10-item PRO. Psychometric testing assessing criterion validity, construct validity, test-retest reliability (TRT) and internal consistency reliability (ICR) were performed. We compared the LIT scores across patient characteristics, and correlations between LIT scores and SLEDAI-2k, PGA, and SLICC-SDI were examined. Results LIT data were obtained from 73 patients. Patients were 84% female with a median age of 41 years, and 34% were Asian. The cohort had mild-moderate disease activity with a median (IQR) Systemic Lupus Erythematosus Disease Activity Index-2000 (SLEDAI-2k) of 4 (IQR 2–6). The median LIT score was 32.5 (IQR 17.5–50). LIT demonstrated criterion validity against SLEDAI-2k and SDI. Construct validity assessed by confirmatory factor analysis demonstrated an excellent fit (Goodness of fit index 0.95, Comparative Fit Index 1, Root Mean Square Error of Approximation <0.0001). The LIT demonstrated TRT with an overall intraclass correlation coefficient of 0.986 (95% CI 0.968–0.995). ICR was demonstrated with a Cronbach’s alpha of 0.838. Patients with disability, low socioeconomic status, or higher disease activity had significantly worse LIT scores. Conclusion The LIT demonstrated properties consistent with its being valid in this population. Lower socioeconomic status appears to have a significant impact on patient-reported health-related quality of life in SLE.

Full textAbstract:
Cluster test selection is a new successful approach to select a subset of the existing test suite in regression testing. In this paper, program slicing is introduced to improve the efficiency and effectiveness of cluster test selection techniques. A static slice is computed on the modified code. The execution profile of each test case is filtered by the program slice to highlight the parts of software affected by modification, called slice filtering. The slice filtering reduces the data dimensions for cluster analysis, such that the cost of cluster test selection is saved dramatically. The experiment results show that the slice filtering techniques could reduce the cost of cluster test selection significantly and could also improve the effectiveness of cluster test selection modestly. Therefore, cluster test selection by filtering has more potential scalability to deal with large software.

The choice of drugs for the treatment of interstitial lung disease (ILD) associated with systemic sclerosis (SS) is currently very limited. Data from a number of studies show that rituximab (RTM) can improve lung function and reduce the severity of skin fibrosis in patients with SS.Objective: to evaluate the efficiency of RTM in a cohort of patients with SS-associated ILD after one-year follow-up. The indications for prescribing RTM were: 1) the inefficiency of standard therapy with glucocorticoids and immunosuppressants (ISs) or the impossibility of their use; 2) the early stage (first 3 years of the disease) with signs of poor prognosis, such as diffuse form, high skin scores (>14), male gender, rapid progression with a significant initial decline in forced vital capacity (FVC) and/or diffusion lung capacity (DLC), and a high anti-Scl-70 antibody positivity.Subjects and methods. The investigators selected a group of patients who had at least two assessment points at a 12-to-18 month interval (the mean follow-up period of 13±2 months) and took at least 1 g of RTM during this period. The investigation included 71 patients with a valid diagnosis of SS. Multi-slice spiral computed tomography (MSCT) revealed ILD in 90% of patients. The disease duration was 5.6±4.4 years. The presence of anti-Scl-70 antibodies was detected in 73% of patients. The mean cumulative dose of RTM was 1.43±0.6 g; 48 patients in Group 1 received ≤2 g of RTM (the mean dose, 1.1±0.1 g) and 23 patients in Group 2 took ≥2 g of RTM (mean dose, 2±0.6 g). Before starting treatment with RTM, all the patients received concomitant therapy with prednisone and 45% - with immunosuppressants.Results and discussion. The results assessed by a physician showed that good and moderate effects of the therapy were observed in 52 (73.2%) and 16 (22.6%) patients, respectively; no effect was seen in 3 (4.2%) patients. Overall, 95.8% of patients reported various degrees of improvement. There were significant changes as reductions in the disease activity index, skin scores, C-reactive protein and IgG levels, the number of patients with a high antinuclear antibody level, and the mean dose of prednisolone as well as increases in an oral aperture size, left ventricular ejection fraction, and 6-minute walk test scores. There were no changes in pulmonary artery systolic pressure and the HAQ DI. FVC increased from 77.35±19.9 to 82.6±20.7% (p=0.001). A minimal clinically significant increase in FVC ≥5% was noted in 41 (57.7%) people. The overall improvement in FVC (ΔFVC) reached 5.24%, while the changes were more significant in Group 2 (ΔFVC 8.98%) than in Group 1 (ΔFVC 3.75%; p=0.01). DLC remained stable, but there were significant group differences: ΔDLC was 3.75% in Group 2 and, conversely, decreased in Group 1 (1.6%; p=0005). The safety profile of the therapy was regarded as good and quite comparable with both the safety profile of ISs and the use of RTM in other trials. Infectious complications were recorded to be most common in 11 (15%) people. Of these, upper respiratory tract infections developed in 7 patients; plantar phlegmon occurred in one case; urinary tract infection and herpes zoster were detected in two and one cases, respectively.The results of this study confirm data from other studies that have demonstrated that RTM exerts a positive effect on SS-associated ILD. We were the first to show the association of positive changes in the measures of pulmonary function tests with the dose of RTM.

Objectives This study aims to investigate the previously reported dependency of intravoxel incoherent motion (IVIM) parameters on simultaneous multislice (SMS) acquisition and repetition time (TR). This includes the influence of slice thickness, slice gaps, and slice order on measured IVIM parameters. Materials and methods Diffusion-weighted imaging (DWI) of the liver was performed on 10 healthy volunteers (aged 20–30 years) at 3T with a slice thickness of 5 mm, a slice gap of 5 mm, and a linear slice order. Diffusion-weighted images were acquired with 19 b-values (0–800 s/mm2) using both conventional slice excitation with an acceleration factor of one (AF1) and SMS excitation with an acceleration factor of three (AF3). Each of these measurements were carried out with two repetition times (TRs)– 1,300 ms (prefix s) and 4,500 ms (prefix l)–resulting in four different combinations: sAF1, sAF3, lAF1, and lAF3. Five volunteers underwent additional measurements using a 10 mm slice thickness and with AF1. Median signal values in the liver were used to determine the biexponential IVIM parameters. Statistical significances were assessed using the Kruskal-Wallis test, Wilcoxon signed-rank test, and Student’s t-test. In-silico investigations were also used to interpret the data. Results There were no significant differences between the biexponential IVIM parameters acquired from sAF1, sAF3, lAF1, and lAF3. Median values of the perfusion fraction f were as follows: 29.9% (sAF1), 26.9% (sAF3), 28.1% (lAF1), and 27.5% (lAF3). In the 10 mm-thick slices, f decreased from 31.3% (lAF1) to 27.4% (sAF1) (p = 0.141). Conclusion The slice excitation mode did not appear to have any significant influence on the biexponential IVIM parameters. However, our simulations, as well as values reported from previous publications, show that slice thickness, slice gaps, and slice order are relevant and should thus be reported in IVIM studies.

Sonneratia ovata is a mangrove fruit that has a distinctive aroma and sour taste, making it suitable for processing into jam. Slice jam is a modified form of spreadable jam that is more practical in serving. The purpose of this study was to determine the effect of drying time on the consumer acceptance of Sonneratia ovata slice jam. The research used a Completely Randomized Design (CRD) with different drying times for slice jam (120 minutes, 150 minutes, 180 minutes and 210 minutes) and three replications. Data analysis using Kruskal-Wallis, if there is a different between the treatment continued by the Multiple Comparisons test. The results showed that the drying time had a significant effect (p<0.05) on the consumer acceptance of Sonneratia ovata slice jam. 210 minutes of drying time (P4) is the best treatment based on the hedonic test value of appearance, aroma, taste, texture and overall parameters. Panelists like the appearance of Sonneratia ovata slice jam, which has brown reddish color and compact texture, but panelists dislike the smell and the sour taste of slice jam.

Full textAbstract:
Height is a key factor in monitoring the growth status and rate of crops. Compared with large-scale satellite remote sensing images and high-cost LiDAR point cloud, the point cloud generated by the Structure from Motion (SfM) algorithm based on UAV images can quickly estimate crop height in the target area at a lower cost. However, crop leaves gradually start to cover the ground from the beginning of the stem elongation stage, making more and more ground points below the canopy disappear in the data. The terrain undulations and outliers will seriously affect the height estimation accuracy. This paper proposed a ground point fitting method to estimate the height of winter wheat based on the UAV SfM point cloud. A canopy slice filter was designed to reduce the interference of middle canopy points and outliers. Random Sample Consensus (RANSAC) was applied to obtain the ground points from the valid filtered point cloud. Then, the missing ground points were fitted according to the known ground points. Furthermore, we achieved crop height monitoring at the stem elongation stage with an R2 of 0.90. The relative root mean squared error (RRMSE) of height estimation was 5.9%, and the relative mean absolute error (RMAE) was 4.6% at the stem elongation stage. This paper proposed the canopy slice filter and fitting missing ground points. It was concluded that the canopy slice filter successfully optimized the extraction of ground points and removed outliers. Fitting the missing ground points simulated the terrain undulations effectively and improved the accuracy.

Abstract Quantifying the inner structure of bones is central to various analyses dealing with the phenotypic evolution of animals with an ossified skeleton. Computed tomography allows to assess the repartition of bone tissue within an entire skeletal element. Two parameters of importance for such analyses are the global compactness (Cg) and total cross-sectional area (Tt.Ar). However, no open-source, time-efficient methods are available to acquire these parameters for whole bones. A methodology to assess the variation of these parameters along a profile following one of the studied bone’s anatomical axes is also wanting. Here I present an ImageJ macro and associated R script to automatically acquire Cg and Tt.Ar along an axis of the skeletal element of interest using a slice-by-slice approach. No manual segmentation is required and several bones can be present on the analysed scan, as long as the bone of interest is isolated and the largest element on each slice. While some bias might be involved by the automatic acquisition, semi-automatic slice exclusion and correction procedures can be used to efficiently account for it. As a test case, µCT-data was gathered for the mid-lumbar vertebra of over 70 mammals. The two evaluated correction procedures proved to perform equally well, with a slight advantage for the one relying on the exclusion of local outliers. The presented macro allows to efficiently build a dataset concerned with the quantification of bone inner structure. The code being readily available, further improvement of the methodology and adjustment to particular needs can be easily performed.

Background Although computed tomography (CT) studies on machines with more slices have reported higher positive and negative predictive values, the impact of using low-slice (16-slice) CT machines on downstream testing has not been well studied. In community outpatient settings, low-slice CT machines remain in use, although many hospitals have adopted higher-slice machines. Objective This study examines the association between the use of low-slice CT machines and downstream invasive testing in the context of the CT angiography of the neck. Methods Included health insurance claims pertained to adults with commercial or Medicare Advantage health plans who underwent the CT angiography of the neck. Site certification data were used to assign counts of slices to claims. Claims that were made in the 60 days after CT were examined for cervicocerebral angiography. The association between the number of slices and cervicocerebral angiography was evaluated by using a chi-square test and multivariate logistic regression. Results Claims for 16-slice CT had a 5.1% (33/641) downstream cervicocerebral angiography rate, while claims for 64-slice CT had a 3.1% (35/1125) rate, and a significant difference (P=.03) was observed. An analysis that was adjusted for patient demographics also found a significant relationship (odds ratio 1.64, 95% CI 1.00-2.69; P=.047). Conclusions The use of low-slice CT machines in the community may impact the quality of care and result in more downstream testing.

Ginger has a fairly high fiber content that can affect the flour produced when it goes through the powdering process. The purpose of this research was to determine the effect of the direction and the thickness of ginger slices on the level of flour fineness. The experiment was conducted by using a completely randomized design (CRD) with two factors. The first factor is the direction of the slice with two treatments, namely vertical slice (V) and horizontal slice (H). The second factor was the thickness of the slices with three levels, namely 2 mm (T1), 4 mm (T2), and 6 mm (T3). It treatment combination was carried out in triplicates. The parameters observed were moisture content, repose angle, degree of fineness, uniformity index, grain yield, bulk density, and color. The data obtained were analyzed by using Anova test available in Excel and SAS, if there is significant different among the parameters, then is followed by LSD test at α = 0,05. The results showed that the direction of slices significantly affect the fineness of the flour, in which vertically sliced cuts produced better fineness than that of horizontally sliced cuts. The thickness of cuts did not significantly influence the flour characteristic. Keywords: Fineness, Ginger, Ginger Fiber, Ginger Flour, Slice Direction, Thickness of the Slices.

Research has been conducted on the effect of slice thickness variation on the quality of Genu MRI images. This study was conducted at the Radiology Installation of Bali Mandara Hospital using primary data from Genu MRI examination results.The independent variable in this study is the variation of slice thickness values of 3, 5, and 7 mm. There were 30 patientsmeasured and the tissues analyzed were ligament, bone, fat, and noise as background using the ROI method and the segmentation results wereresults were taken at the mean value and standard deviation in the background. The difference in SNR and CNR values due to variations in slice thickness values can be tested using the Factorial Anova test. The results of this study obtained that there is an effect of slice thickness variation on SNR and CNR values that will have an impact on the quality of MRI Genu images. The greater the slice thickness value analyzed, the greater the SNR and CNR values produced and the better the image quality. In ligament tissue, the average SNR values of 3, 5 and 7 mm are 23.830; 36.594; and 50.524, respectively. In bone tissue, 191.352; 277.399, and 344.170 were obtained. In fat tissue, SNRs of 9,460, 292,022, and 367,463 were obtained. Changing the slice thickness will directly affect the SNR. It can be seen that the higher the slice thickness value given, the higher the SNR and CNR values for each tissue evaluated and the longer the scanning time required.

The detector description is an essential component to analyze data resulting from particle collisions in high energy physics experiments. The interpretation of data from particle collisions typically requires auxiliary data which describe in detail the state of the experiment. These accompanying data include alignment parameters, parameters describing the electronics as well as calibration- and environmental constants. We present a mechanism to manage such data in multiple simultaneous versions depending on their validity. The detector conditions data are made available to the physics algorithms through a number of transient objects grouped to collections. Such a collection represents a coherent slice of all conditions data necessary to process one or several events depending on the valid interval of the slice being the intersection of the individual conditions. A multi-threaded application may hold several such collections in parallel depending on the time-stamps of the events currently processed. Once prepared, these collections are read-only and can easily be shared between threads with minimal requirements for locking and hence minimal overhead. We deliberately restrained ourselves from providing a persistent data solution, which in the past were fields of expertise of the experiments, but rather provided the necessary hooks to populate the conditions cache. We will present the use-cases that have driven the development, the main design choices and details of the implementation.

BackgroundMissed injury of the diaphragm may result in hernia formation, enteric strangulation, and death. Compounding the problem, diaphragmatic injuries are rare and difficult to diagnose with standard imaging. As such, for patients with high suspicion of injury, operative exploration remains the gold standard for diagnosis. As no current data currently exist, we sought to perform a pragmatic evaluation of the diagnostic ability of 256-slice multidetector CT scanners for diagnosing diaphragmatic injuries after trauma.MethodsA retrospective review of trauma patients from 2011 to 2018 was performed at an American College of Surgeons-verified level 1 trauma center to identify the diagnostic accuracy of CT scan for acute diaphragm injury. All patients undergoing abdominal operation were eligible for inclusion. Two separate levels of CT scan technology, 64-slice and 256-slice, were used during this time period. The prospective imaging reports were reviewed for the diagnosis of diaphragm injury and the results confirmed with the operative record. Injuries were graded using operative description per the American Association for the Surgery of Trauma guidelines.ResultsOne thousand and sixty-eight patients underwent operation after preoperative CT scan. Acute diaphragm injury was identified intraoperatively in 14.7%. Most with diaphragmatic injury underwent 64-slice CT (134 of 157, 85.4%). Comparing patients receiving 64-slice or 256-slice CT scan, there was no difference in the side of injury (left side 57.5% vs. 69.6%, p=0.43) or median injury grade (3 (3, 3) vs. 3 (2, 3), p=0.65). Overall sensitivity, specificity, and diagnostic accuracy of the 256-slice CT were similar to the 64-slice CT (56.5% vs. 45.5%, 93.7% vs. 98.1%, and 89.0% vs. 90.2%).DiscussionThe new 256-slice multidetector CT scanner fails to sufficiently improve diagnostic accuracy over the previous technology. Patients with suspicion of diaphragm injury should undergo operative intervention.Level of evidenceI, diagnostic test or criteria.

Kaya Slice is a nutritious traditional breakfast-on-the-go that was innovated from the traditional kaya. In this study, the traditional kaya was transformed into square shape gelatin to make it a more convenient and ready-to-eat breakfast. A total of six formulations were developed by using commercial and fresh coconut milk together with different percentages of gelatin (2%, 4%, and 6%). This insight was investigated by sensory evaluation using a 9-point hedonic and scoring test in descriptive data set. The best formulation obtained from the evaluation of 35 panellists was then characterized in terms of physicochemical properties (Texture Profile Analysis (firmness), Brix, Protein, Fat, Fiber, and Calories). From the descriptive data, all formulations were accepted by the panellist. Nevertheless, ANOVA analysis indicated that C2 (commercial coconut milk + 4% of gelatin) is the best formulation. In macronutrient analysis, Kaya Slice was found to have good dietary fibre content (0.11 g/100 g), high-fat content (0.49 g/100 g), protein content (0.32 g/100 g) compare to the commercial kaya (0.00 g/100 g), (1.00 g/100 g), and (0.00 g/100 g) respectively. Low-calorie content in Kaya Slice with 45 % of °Brix value is the minimal degree of Brix and the texture was softer (hardness) (significantly different (p<0.05)) to commercially processed cheese slice as standard. Overall, Kaya Slice has a great potential in becoming new emergent of traditional nutritious breakfast on the go.

<abstract><p>With the continuous improvement of biological detection technology, the scale of biological data is also increasing, which overloads the central-computing server. The use of edge computing in 5G networks can provide higher processing performance for large biological data analysis, reduce bandwidth consumption and improve data security. Appropriate data compression and reading strategy becomes the key technology to implement edge computing. We introduce the column storage strategy into mass spectrum data so that part of the analysis scenario can be completed by edge computing. Data produced by mass spectrometry is a typical biological big data based. A blood sample analysed by mass spectrometry can produce a 10 gigabytes digital file. By introducing the column storage strategy and combining the related prior knowledge of mass spectrometry, the structure of the mass spectrum data is reorganized, and the result file is effectively compressed. Data can be processed immediately near the scientific instrument, reducing the bandwidth requirements and the pressure of the central server. Here, we present Aird-Slice, a mass spectrum data format using the column storage strategy. Aird-Slice reduces volume by 48% compared to vendor files and speeds up the critical computational step of ion chromatography extraction by an average of 116 times over the test dataset. Aird-Slice provides the ability to analyze biological data using an edge computing architecture on 5G networks.</p></abstract>

The purpose of this study was to evaluate a method for the quantification of through-plane flow velocities by magnetic resonance imaging (MRI) from the flow characteristics of conventional multiple spin-echo (MSE) signals. Simulated inflow-outflow-dependent signals, as well as images of a flow phantom were generated and the logarithm of the flow-dependent signal value was plotted against echo time. The normalized slope of the resulting curve was calculated using a least-square fit to simulated and experimental data and was corrected for T2 relaxation effects by subtraction of a slope obtained at zero flow. After this correction, and with certain restrictions regarding the flow velocity (v), maximum number of echoes in the slope calculation and slice thickness (L), the normalized slope of the MSE signal becomes equal to the quotient v/L, and from this relation the flow velocity can be determined. The validity of the proposed method was examined for different flow velocities and for two opposite flow directions. The influence of the size of the region of interest and the number of spin echoes used in the calculation of the slope on the accuracy of the velocity determination was also studied. The sensitivity of the method to flow-induced phase changes was examined in the phantom by comparing the results obtained with different strengths of the slice-selective gradient as well as by comparing results from even-echo data with those from odd-echo data. When applied to simulated signal data, the method was found to be strictly valid only for a small velocity range, while for the flow phantom, the calculated velocities corresponded to measured velocities for values up to and over 100 mm/s. In the phantom experiment, the method was found to be insensitive to effects induced by combined changes of the slice thickness and the slice-selective gradient as well as to so-called even-echo rephasing effects. It is concluded that the examined method promises to be a rapid and easily interpretable alternative to other methods, e.g. magnetic resonance velocity-phase encoding, for the determination of flow velocities in vivo.
