Abstract:

Chordae tendineae rupture (CTR) is a potentially life-threatening cardiac event often resulting in Acute mitral regurgitation (AMR). We assessed Post-traumatic stress disorder (PTSD), depression, and anxiety symptoms in n=21 CTR patients with AMR (age 82.3 ± 4.2 years; 66.7% men) and compared them to n=23 CTR patients with Chronic mitral regurgitation (CMR) and n=35 Myocardial infraction (MI) patients. Regression analyses revealed that PTSD scores were significantly higher in CTR patients with AMR than in CTR patients with CMR or MI patients. CTR patients with CMR had the lowest levels of PTSD-symptoms. Depression and anxiety scores were elevated across all three groups. Our results suggest that psychosocial factors need to be considered in CTR patients’ care.

Abstract:

The continuum robot is a new type of bionic robot which is widely used in the medical field. However, the current structure of the continuum robot limits its application in the field of minimally invasive surgery. In this paper, a bio-inspired compound continuum robot (CCR) combining the concentric tube continuum robot (CTR) and the notched continuum robot is proposed to design a high-dexterity minimally invasive surgical instrument. Then, a kinematic model, considering the stability of the CTR part, was established. The unstable operation of the CCR is avoided. The simulation of the workspace shows that the introduction of the notched continuum robot expands the workspace of CTR. The dexterity indexes of the robots are proposed. The simulation shows that the dexterity of the CCR is 1.472 times that of the CTR. At last, the length distribution of the CCR is optimized based on the dexterity index by using a fruit fly optimization algorithm. The simulations show that the optimized CCR is more dexterous than before. The dexterity of the CCR is increased by 1.069 times. This paper is critical for the development of high-dexterity minimally invasive surgical instruments such as those for the brain, blood vessels, heart and lungs.

Abstract:

This study tries to establish the important factors influencing the dividend payout policy of the Multinational Companies (MNCs) in Bangladesh in order to assist investors in making the best possible investment decisions. Data for this study was collected from several MNCs listed on the DSE from 2015 to 2021. The relationship between the dependent variable, Dividend Payout Ratio (DPR) and selected independent variables such as Return on Equity (ROE), Liquidity Ratio (LEQR), Leverage Ratio (LEVR), Firm Size (FS), Dividend Payout Ratio of Previous Year (PDPR), Corporate Tax Ratio (CTR) and Capital Adequacy Ratio (CAR) is evaluated using Pearson's correlation and Ordinary Least Squares (OLS) regression models for data analysis and hypothesis testing. The regression analysis results showed a mixed result. The ROE and CTR are significantly related to DPR. Higher ROE and CTR emphasis a higher dividend for stock holders. The FS is significantly negatively related to DPR. Due to the costs associated with paying for the profits of substantial assets, large firms pay lower dividends. Other variables such as LEQR, LEVR, PDPR, CTR and CAR have no significant impact on the DPR. The investors and the concerned authorities can consider ROE, CTR and FS to forecast the future dividend for the MNCs in Bangladesh.

Abstract:

Left ventricular hypertrophy (LVH) is associated with adverse clinical outcomes and implicates clinical decision-making. The aim of our study was to assess the importance of different approaches in the screening for LVH. We included patients who underwent cardiac magnetic resonance (CMR) imaging and had available chest radiograph in medical documentation. Cardiothoracic ratio (CTR), transverse cardiac diameter (TCD), clinical and selected electrocardiographic (ECG)-LVH data, including the Peguero-Lo Presti criterion, were assessed. CMR–LVH was defined based on indexed left ventricular mass-to-body surface area. Receiver operating characteristics analyses showed that both the CTR and TCD (CTR: area under the curve: [AUC] = 0.857, p < 0.001; TCD: AUC = 0.788, p = 0.001) were predictors for CMR–LVH. However, analyses have shown that diagnoses made with TCD, but not CTR, were consistent with CMR–LVH. From the analyzed ECG–LVH criteria, the Peguero-Lo Presti criterion was the best predictor of LVH. The best sensitivity for screening for LVH was observed when the presence of heart failure, ≥40 years in age (each is assigned 1 point), increased TCD and positive Peguero-Lo Presti criterion (each is assigned 2 points) were combined (CAR2E2 score ≥ 3 points). CAR2E2 score may improve prediction of LVH compared to other approaches. Therefore, it may be useful in the screening for LVH in everyday clinical practice in patients with prevalent cardiovascular diseases.

Abstract:

Calcitonin (CT) and calcitonin gene-related peptide (CGRP) are critical regulators of calcium balance and have extensive implications for vertebrate physiological processes. This study explores the CT and CGRP signaling systems in chickens through cloning and characterization of the chicken calcitonin receptor (CTR) and calcitonin receptor-like receptor (CLR), together with three receptor activity-modifying proteins (RAMPs). We illuminated the functional roles for chickens between the receptors examined alone and in RAMP-associated complexes using luciferase reporter assays. Chicken CTRs and CLRs stimulated the cAMP/PKA and MAPK/ERK signaling pathways, signifying their functional receptor status, with CT showing appreciable ligand activity at nanomolar concentrations across receptor combinations. Notably, it is revealed that chicken CLR can act as a functional receptor for CT without or with RAMPs. Furthermore, we uncovered a tissue-specific expression profile for CT, CGRP, CTR, CLR, and RAMPs in chickens, indicating the different physiological roles across various tissues. In conclusion, our data establish a clear molecular basis to reveal information on CT, CGRP, CTR, CLR, and RAMPs in chickens and contribute to understanding the conserved or divergent functions of this family in vertebrates.

Abstract:

Tourism is the backbone of any country's economic development. Domestic and offshore tourism was the most affected by the COVID-19 crisis, and more than any other sector globally in China. China's once flourishing tourism industry has endured a significant impact due to travel restrictions, regional isolation, and quarantine measures. This study focusses on historical tourist economic data from the micro to the macro level in order to assess the impact of tourism on Chongqing's and China's economy both before and after the pandemic crisis. The study used the vector error correction model (VECM) to quantitatively analyze data on Chongqing Gross Domestic Product (GDP), China tourism revenue (CTR) and Chongqing tourism revenue (CQTR) for the period from 2004 to 2023. The results show that COVID-19 leads to a significant decline in tourism-related income. In terms of the relationship between the two, after quantitative analysis of variance the effect of CQTR on Chongqing GDP is unidirectional rather than the main cause of Chongqing GDP, and the relationship between CQTR and CTR is bidirectional and interacts with it. This also explains why the CQTR dramatically drops in 2021–2023 while Chongqing GDP grows continuously and shows the reason why CQTR and CTR go up or down in the same trend.

Abstract:

An altered ceramide composition in patients with inflammatory bowel disease (IBD) has been reported recently. The aim of this study was to evaluate the concentrations of sphingolipids in the serum of treatment-naive children with newly diagnosed IBD and to determine the diagnostic value of the tested lipids in pediatric IBD. The concentrations of sphingolipids in serum samples were evaluated using a quantitative method, an ultra-high-performance liquid chromatography-tandem mass spectrometry in children with Crohn’s disease (CD) (n=34), ulcerative colitis (UC) (n = 39), and controls (Ctr) (n = 24). Among the study groups, the most significant differences in concentrations were noted for C16:0-LacCer, especially in children with CD compared to Ctr or even to UC. Additionally, the relevant increase in C20:0-Cer and C18:1-Cer concentrations were detected in both IBD groups compared to Ctr. The enhanced C24:0-Cer level was observed only in UC, while C18:0-Cer only in the CD group. The highest area under the curve (AUC), specificity, and sensitivity were determined for C16:0-LacCer in CD diagnosis. Our results suggest that the serum LacC16-Cer may be a potential biomarker that distinguishes children with IBD from healthy controls and differentiates IBD subtypes. In addition, C20:0-Cer and C18:0-Cer levels also seem to be closely connected with IBD.

Abstract:

The structure of modern employment continues to evolve with substantial growth occurring in contractual tripartite relationships. In this thesis there is an exploration of the contractual (non-employment) tripartite relationship between employment agents, hosts and technical white-collar contractors in Australia's mining, technical, consulting and construction sectors. In this thesis the challenges associated with managing the tripartite relationship are investigated using the theoretical lenses of agency, psychological contract, and power to examine the perspectives of the three groups within the relationship. The findings reveal confusion regarding the roles and incumbent responsibilities of the agents, hosts, and contractors. All three groups are uncertain as to which of them is responsible for the contractor in this complicated three-way relationship. Implications and recommendations for future research and practice changes are noted.

Abstract:

In questa tesi vengono presentati degli studi su un prototipo di rivelatore per un modulo PET con cristallo segmentato, condivisione della luce e lettura della stessa da una singola faccia. Un apparato sperimentale dedicato è stato inizialmente sviluppato e caratterizzato, per poter soddisfare tutti i requisiti in termini di risoluzione spaziale, temporale ed energetica. Questo setup permette la lettura di molteplici canali con catene parallele per misure di tempo ed energia e numerose possibilità di automazione, date dalle molteplici meccaniche impiegabili. La flessibilità di questo apparato ha permesso di effettuare i successivi studi impiegando gli stessi software di acquisizione e analisi. Inoltre, apre la possibilità di ulteriori test su detector a molti canali e per la ricostruzione di immagini. La prima applicazione di questo setup è stato il miglioramento della risoluzione temporale di coincidenza di un modulo PET usando l'informazione relativa alla profondità di interazione. Il contributo alla risoluzione temporale dovuto alle differenti velocità di propagazione di fotoni gamma e ottici all'interno del detector è stata mitigata con un algoritmo che richiede solamente una misura di calibrazione rispetto al rivelatore impiegato. Per ottenere la migliore risoluzione temporale possibile in questa configurazione, molteplici marche temporali sono state combinate per ottenere una miglior stima del tempo di interazione. Questo lavoro è particolarmente interessante per una possibile applicazione in macchine PET ad alta risoluzione, in quanto impiega una lettura della luce da un singola faccia e richiede costi di produzione solo leggermente superiori in confronto a moduli esistenti simili sprovvisti di informazione DOI. Inoltre, è stato sviluppato un algoritmo per identificare correttamente il cristallo di prima interazione nei casi di scattering Compton tra cristalli. Questi sono eventi in cui il fotone gamma primario interagisce con più di un canale della macchina PET. Diversi approcci al problema sono usati in letteratura; uno di questi è l'uso di un algoritmo per riordinare le deposizioni di energia. Questo è l'approccio usato anche in questo studio: è stato sviluppato un nuovo algoritmo, è stato testato con simulazioni Geant4 ed è stato applicato a un modulo PET precedentemente sviluppato usando il setup sperimentale inizialmente sviluppato. La possibilità di includere eventi ICS con una buona accuratezza potrebbe permettere di aumentare la sensitività o la qualità dell'immagine, a seconda di quale metodo è messo a confronto. La possibilità a lungo termine di questo algoritmo sono discusse in conclusione.
In this thesis we will present different studies carried out on a prototype of PET module detector with pixelated crystals, light sharing and single side readout. A dedicated experimental setup was initially developed and characterised, in order to satisfy all the requirements in terms of spatial, energy and time resolution. This setup allows multiple channels readout with parallel chains for energy and time measurement and various possibilities for automation given by several possible mechanics arrangement. The flexibility of this setup allowed to perform all the successive studies using the same Data Acquisition electronics and software. Moreover, it opens up the possibilities for further tests on multi-channels detectors and on image reconstruction. The first application of this setup was the improvement of the Coincidence Time Resolution of the PET module exploiting Depth Of Interaction information. The contribution to the time resolution due to different speed of gamma and optical photons inside the detector was mitigated with an algorithm that only requires a calibration measurement compared to the DOI capable prototype used. To achieve the best possible time resolution in this configuration, multiple time stamps were combined to obtain a better time of interaction estimator. This work is particularly interesting for possible application in high resolution PET scanners, because it relies on single side readout and requires production costs only slightly higher compared to a similar existing module without DOI capability. Moreover, an algorithm was developed to correctly identify the crystal of first interaction in case of Inter-Crystal Scatter events. These are events in which the primary gamma photon interacts with multiple channels of the PET detector. Different approaches to the subject are found in literature; one of these is to use an algorithm to sort the energy depositions. This is the approach used in this study: a new algorithm was developed, preliminary tested by means of Geant4 simulations and later applied on the PET module previously developed using the experimental setup originally described. The possibility to include ICS event with good accuracy would allow to increase sensitivity or image quality depending on the method to whom this approach is compared to. The long term possibilities of this algorithm will be discussed further at the end of this thesis.

Abstract:

The thesis explores cooperative security efforts between the United States and Russia in the framework of the Cooperative Threat Reduction (CTR) Programme and other non-proliferation programmes, which were established in the aftermath of the Soviet collapse as a response to nuclear proliferation threats in the former Soviet Union. One of the main objectives of CTR is to reduce nuclear dangers associated with vast nuclear arsenals, which first and foremost, means reductions in nuclear weapons. This work presents an overview of different proliferation threats ranging from proliferation of nuclear material to potential “brain-drain” from the former Soviet nuclear complex, explains their technical and socio-economic aspects and assesses the effectiveness of the U.S.-Russian programmes, which deal with these threats. The CTR process has encountered some major obstacles on its way. The research suggests that some important problems in the implementation of CTR programmes are of bureaucratic nature. However, bureaucratic factors are aggravated by the political factors stemming from the fact that the national security policies of the U.S. and Russia are still in part based on concepts and strategies adopted during the Cold War. This is especially evident with regard to the role assigned to nuclear weapons by both countries. Therefore, the CTR process is used as a laboratory study of the U.S.-Russian strategic relations in the post-Cold War era. The study demonstrates that the processes happening in the international security system below the surface and which might not be so obvious at a glance can be absolutely important for the future of the international system. The CTR process represents a mechanism, which can be used to build a new international system, where the role of the nuclear weapons becomes more and more obsolete.

Abstract:

Purpose – The purpose of this study is partly to illustrate how the AES encryption methods ECB and CTR affect the computational speed when using the GPGPU framework Cuda, but also to clarify the advantages and disadvantages between the different AES encryption modes. Method – A preliminary study was conducted to obtain empirical data on the AES encryption modes ECB and CTR. Data from the study has been analyzed and compared to determine the various aspects of the AES encryption modes and to create a basis for determining the advantages and disadvantages between them. The preliminary study has been carried out systematically by finding scientific works by searching databases within the subject. An experiment has been used as a method to be able to extract execution time data for the GPGPU framework Cuda when processing the AES encryption modes. Experiment were chosen as a method to gain control over the variables included in the study and to see how these variables change when they are consciously influenced. Findings – The findings of the preliminary study show that CTR is more secure than the ECB, but also considerably more complex, which can lead to integrity risks when implementation is done incorrectly. In the experiment, computational speeds are produced when the CPU memory sends to the GPU memory, the encryption on the GPU and how long it takes for the GPU memory to send to the CPU memory. This is done for both CTR and ECB in encryption and decryption. The result of the analysis shows that the ECB is faster than CTR in encryption and decryption. The calculation speed is higher with the ECB compared to the CTR. Implications – The experiment shows that CTR is slower than the ECB. But the most amount of time spent in encryption for both modes are the transfers between the CPU memory and the GPU memory. Limitations – The file sizes of the files tested only goes up to about 1 gigabyte which gave small computation times.

Abstract:

Click-through rate (CTR) estimation plays as a core function module in various personalized online services, including online advertising, recommender systems, and web search etc. From 2015, the success of deep learning started to benefit CTR estimation performance and now deep CTR models have been widely applied in many industrial platforms. In this survey, we provide a comprehensive review of deep learning models for CTR estimation tasks. First, we take a review of the transfer from shallow to deep CTR models and explain why going deep is a necessary trend of development. Second, we concentrate on explicit feature interaction learning modules of deep CTR models. Then, as an important perspective on large platforms with abundant user histories, deep behavior models are discussed. Moreover, the recently emerged automated methods for deep CTR architecture design are presented. Finally, we summarize the survey and discuss the future prospects of this field.

Abstract:

Click-Through Rate (CTR) prediction is used to estimate the probability of a user to click on an item in an online advertising. CTR provides insights in supporting effective online advertising that generates huge advertising revenues and also improve users’ satisfaction. Researchers use various features in their proposed CTR prediction models, and they can be generally classified as advertisement feature, user feature and ad-context feature. Advertisement feature explains “How” an ad serving is, user feature illustrates “Who” is browsing the web pages and lastly the ad-context feature describes “What” the product is, “Where” will an ad displayed and the “Mood” of the web contents from users’ comments. In recent years, there is a transformation on CTR models from the traditional methodologies into deep CTR models. Different studies have emphasized certain features and there is no consensus on the features used in the CTR prediction models to achieve better performance. This paper examines the features used by various CTR prediction models in the online advertising and the various opportunities that are available for future research. Keywords: Ad-context, Click-Through Rate, Deep Interest Evolution Network, Deep Interest Network, Deep Session Interest Network

Abstract:

Review question / Objective: To evaluate the effectiveness and safety of Chinese herbal medicines (CHMs) combined with cyclophosphamide (CTX) for connective tissue disease-associated interstitial lung disease (CTD-ILD) by performing a meta-analysis. Condition being studied: Chinese herbal medicines (CHMs) and cyclophosphamide (CTX) are widely used in the treatment of connective tissue disease-associated interstitial lung disease (CTD-ILD). However, the clinical benefits of CHMs treatment for CTD-ILD are still controversial, and there is no systemic review to summarize and evaluate their efficacy and safety.

Abstract:

Objective: Pancreatic ductal adenocarcinoma (PDAC) has the best survival when detected early with 5-year survival near 40% for small, resectable PDAC. We evaluate the undiagnosed PDAC imaging features on routine CT and their impact on resectability. Methods: 76 of the screened 134 CTs from 1/1/2012 to 12/31/2018 using our tumor registry were obtained prior to PDAC diagnosis for other indications at least one month before presentation. Each cross-sectional study was reviewed for features of early PDAC: pancreatic mass, pancreatic ductal dilatation, perivascular/peripancreatic soft-tissue infiltration, omental lesions/ascites, and lymphadenopathy. When such features were detectible by the reviewing radiologists, the original CT readings were classified as concordant/discrepant. Descriptive statistics are reported for discrepant reads, tumor resectability, and tumor size. Results: Of the 76 cases from 46 unique subjects (30 male/16 female), 25 CTs (33%) had undetected PDAC imaging features: masses (15/19 unreported), ductal dilatation (16/20 unreported), and peripancreatic/perivascular soft-tissue infiltration (20/36 unreported). 63% of early PDAC features were not identified initially. One year before clinical diagnosis, 75-80% of the PDAC cases were resectable; at < 6 months before clinical diagnosis, only 29% were resectable. Conclusion: Improving early detection of key PDAC features on routine CT examinations can potentially improve patient outcomes.

Abstract:

This research report is a case study on the relationship between trauma, peacebuilding, and reintegration for conflict-affected youth in the Central African Republic (CAR) following the 2019 peace agreement. Based on qualitative research fielded in Spring 2022, the study examines how youth experience conflict, trauma, and reintegration in CAR, highlighting individual experiences through a participant narrative approach. In doing so, the report provides localized insight into the challenges that impact social reintegration and cohesion in fragile, conflict-affected contexts. The report further underscores the implications of these insights for local and international efforts to establish peace and security through disarmament, demobilization, and reintegration (DDR) programs and community violence reduction (CVR) initiatives. In addition to standard data collection methods such as interviews and focus group discussions, data collection undertaken for this report utilized a trauma-informed method called body mapping. The use of body maps—life size images of a human body with visual representations of experiences— in research can offer a means for individuals to reflect on potentially difficult experiences through a non-verbal process. Given the potential relevance of this tool in future studies examining the nexus between conflict, reintegration, mental health, and trauma, this report also includes discussion of the implementation of this method with considerations for others hoping to adapt it for their own use.
