Published: October 2019

Significant investments are being made yearly to improve service quality and delivery in banking systems to minimise customers' dissatisfactions with long waiting time due to overcrowding. However, most existing empirical studies to address this problem employed the method where the system was modelled and then developed a program that will simulate, analyse and validate the developed model. This paper conceptualised modelling bank cash deposit transactions characterised by Deposit Slip (DS) using Hierarchical Timed Coloured Petri Nets (HCPN). The HTPC model developed was simulated using Coloured Petri Nets tools. The model was validated by comparing the simulated results with the real average flow time of the customers and utilisation rate of servers using statistical t-test at p< 0.05.
This model is useful for bank decision makers in capacity building to enhance service quality and delivery.

Design, Fabrication and Performance Evaluation of Indigenous Fish Feed Pelletizing Machine for Low Income Farmers in Nigeria
Authors: Orimaye O. S. , Ajewole P. O. , Oni I. O. 
Published: October 2019

The design, fabrication and performance evaluation of a fish feed pelletizing machine for low income farmers was carried out with the view to encourage local technology, as most of the fish feed pelletizing machines available are imported. The fish feed pelletizer is powered by an electric motor and it works by the rotation of a screw auger which propels the feed mix through a die. The screw auger is enclosed in the auger casing and is propelled by an electric motor with the aid of belt and pulleys. This auger is fed through a hopper, which is able to hold a large quantity of the feed mix at a time. The machine was tested using different die diameters of 2 mm, 4 mm and 6 mm. The test was conducted at different moisture content of 10%, 15%, 20%, 25%, 30% and 35% wet basis. The machine test results showed that the pelletizing efficiency increases as moisture content and die diameter increase. The machine throughput also increases with both moisture content and die diameter. Highest efficiency of 98% was obtained when the moisture content was maintained at 25% wet basis and the feed materials were made to pass through 6 mm die diameter. The total cost of the design and construction of this pelletizing machine was one hundred and five thousand naira (N105, 000.00) which is still reasonably affordable by small scale famers.
A Study of Wafer Backgrinding Tape Selection for SOI Wafers
Authors: Bacquian Bryan Christian S. , Gomez Frederick Ray I. 
Published: October 2019

The continuous development and trends on thinner semiconductor packages have become the focus in the semiconductor industry. The necessity of thinner packages also demands a thinner vertical structure of the integrated circuit (IC) design. As a major contributor on the vertical structure of the IC package, die or wafer is also essential to go thinner. As the wafer goes thinner, various problems may occur during transport and even the backgrinding process, itself.
Wafer warpage is one of the main concerns during the backgrinding process. Wafer warpage varies depending on the wafer backgrinding stress and backgrinding tape (hereinafter referred to as BG tape) tension. Hence, tension between the surface protective tape and the wafer should be considered an important and critical item to consider during BG tape selection.
Different silicon wafer technology has been released to cater different functionality on different industry markets. One popular silicon technology is Silicon On Insulator (SOI) technology. SOI wafers have a step type passivation wherein the edge of the wafer is observed to have 30um thinner than its center. The stepping effect also contributes to the 0.5mm wafer warpage prior backgrinding. Evaluating the effect of BG tape selection to eliminate such warpage is discussed on this paper.

Authors: Almashakbeh Atef 
Published: October 2019

Different types of voltage sources are available in the market, but the point is how to convert any voltage to our desired waveform? For example; if we have a DC voltage source (like battery or dc generator) and we need to run AC motor (one phase or three phases) or run DC motor with special voltage, or we have an AC source (one phase or three phases) and need to run AC machine with special voltage and special frequency or run DC machine with special voltage. In simple meaning we need a connector between the sources and loads to match between them. But it should pass this conditions; efficiency, mobility, size, weight, range of operation, simple with using and cost.
This paper focuses on designing and producing a true sinewave inverter that provides premium power which is identical to (or even better than) the power supplied by the utility company with multi output. On this work we will give an explanation for type of inverter depend on output and function for it.
Formalizing a Postprocessing Procedure for Linear–Convex Combination Forecasts
Authors: Monschang Verena , Wilfling Bernd 
Published: December 2024

ABSTRACTWe investigate mean squared forecast error (MSE) accuracy improvements for linear–convex combination forecasts, whose components are pretreated by a postprocessing procedure called “vector autoregressive forecast error modeling” (VAFEM). Assuming that the forecast error series of the individual forecasts are governed by a stable VAR process under classic conditions, we obtain the following results: (i) VAFEM treatment bias corrects all individual and linear–convex combination forecasts. (ii) Any VAFEM‐treated combination has a smaller theoretical MSE than its untreated analog, if the VAR parameters are known. (iii) In empirical applications, VAFEM gains depend on (1) in‐sample sizes, (2) out‐of‐sample forecast horizons, and (3) the biasedness of the untreated forecast combination. We demonstrate the VAFEM capacity in simulations and for realized‐volatility forecasting, using S&P 500 data.

Published: December 2024

AbstractSevere fever with thrombocytopenia syndrome (SFTS) is an emerging infectious disease that results from SFTS bunyavirus (SFTSV) infection. Infection with SFTSV can activate the immune system, producing a series of inflammatory factors. Some patients, particularly those with pre‐existing conditions or at an advanced age, may experience an excessive inflammatory response, triggering systemic multi‐organ failure progressing to severe disease and, potentially, death. In recent years, extensive research has been conducted on the mechanism of SFTSV infection and its interaction with host immune responses. Additionally, a range of biomarkers with significant prognostic value for SFTS have been identified. This review provides a comprehensive summary of the latest advancements in understanding the interplay between SFTSV and host immune responses, and elucidates the role of these biomarkers in the early detection of severe cases and fatal outcomes. The insights presented aim to inform strategies for early intervention, clinical treatment, and prognostic assessment of patients with SFTS.

Published: December 2024

ABSTRACTAimsTo identify the effects of moral distress and terminal care stress on the terminal care performance of nurses who cared for COVID‐19 patients.DesignThis study was cross‐sectional descriptive research.MethodsUsing a convenience sampling method from June to October 2022, nurses who provided terminal care for COVID‐19 patients in a Korean tertiary hospital within the last 6 months from the time of the study were selected as participants. Socio‐demographic and work characteristics of the participants were collected, and COVID‐19 moral distress, terminal care stress and terminal care performance were assessed. A total of 140 self‐report questionnaires were distributed and returned (response rate: 100%).ResultsIn the terminal care performance, it was found that nurses performed relatively well in the physical area, but less well in the emotional and spiritual areas. Moral distress and terminal care stress were both positively correlated with terminal care performance for nurses who cared for COVID‐19 patients. The predictors of terminal care performance were moral distress (β = 0.27, p = 0.003), gender (β = 0.20, p = 0.015) and experience in a dedicated COVID‐19 unit (β = 0.22, p = 0.020).ConclusionsThe study identified moral distress as the most significant factor influencing terminal care performance among nurses caring for COVID‐19 patients. To enhance terminal care performance, it is crucial to address moral distress and provide clear guidelines and support, especially in the emotional and spiritual care domains. Future research should explore additional factors that may influence terminal care performance in pandemic situations.Patient or Public ContributionNo patient or public contribution.

Abstract
Purpose
To investigate the influence of a micro-enema on diagnostic performance, submucosal width, reader confidence, and tumor conspicuity using MRI to stage early rectal cancers (ERC).

Methods
In this single-center study, we consecutively included 50 participants with assumed ERC who all completed MRI with (MRin) and without (MRex) a micro-enema. The diagnostic performance was recorded for two experienced radiologists using histopathology as the gold standard. In addition, the width of the submucosa in the tumor-bearing wall, reader confidence for T-staging, and tumor conspicuity were assessed. Significance levels were calculated using McNemar’s test (diagnostic performance) and Wilcoxon’s signed-rank test (reader confidence, submucosal width, and conspicuity). Interreader agreement was assessed using kappa statistics.

Results
Sensitivity/specificity were for Reader1 91%/87% for both MRex and MRin and for Reader2 74%/87% and 89%/87%, both readers p > 0.05. The micro-enema induced a significant widening of the submucosa, p < 0.001, with a mean increase of 2.2/2.8 mm measured by Reader1/Reader2. Reader confidence in T-staging and tumor conspicuity increased for both readers, p < 0.005. The proportion of tumors with both correct staging and high reader confidence increased from 58% (29/50) to 80% (40/50) (p = 0.04) for Reader1 and from 42% (21/50) to 72% (36/50) (p = 0.002) for Reader2. Interreader agreement increased from moderate (kappa 0.58) to good (kappa 0.68).

Conclusion
The micro-enema significantly increased the submucosal width in the tumor-bearing wall, reader confidence, and tumor conspicuity and improved interreader agreement from moderate to good. Sensitivity and specificity in T-staging did not improve, but there was a significant increase in the proportion of tumors staged with both high confidence and correct T-stage.

Authors: Zarzour Jessica , Revels Jonathan , Rao Korivi Brinda , Martin-Harris Bonnie 
Published: December 2024

AbstractThe modified barium swallow study (MBSS) is a diagnostic examination that visualizes the functional anatomy and physiology of the oral pharyngeal swallowing mechanism in real time. The MBSS, a videofluoroscopic imaging method, is indicated for patients with known or suspected oropharyngeal dysphagia and ideally involves the combined expertise of a radiologist and speech pathologist. The MBSS provides critical diagnostic insights that help in identifying and assessing the type and severity of physiological swallowing impairments, evaluating the safety of oral intake, testing the effectiveness of evidence-based interventions, and developing treatment plans. This manuscript aims to present an overview of MBSS standards from an interdisciplinary perspective, emphasizes key areas of best practices, and reviews the common morphologic abnormalities seen on MBSS exams.
Hawking radiation with pure states
Authors: Kumar K. Sravan , Marto João 
Published: December 2024

Abstract
Hawking’s seminal work on black hole radiation highlights a critical issue in our understanding of quantum field theory in curved spacetime (QFTCS), specifically the problem of unitarity loss (where pure states evolve into mixed states). In this paper, we examine a recent proposal for a direct-sum QFTCS, which maintains unitarity through a novel quantization method that employs geometric superselection rules based on discrete spacetime transformations. This approach describes a quantum state in terms of components that evolve within geometric superselection sectors of the complete Hilbert space, adhering to the discrete symmetries of a Schwarzschild black hole. Consequently, it represents a maximally entangled pure state as a direct-sum of two components in the interior and exterior regions of the black hole, thereby preserving the unitarity of Hawking radiation by keeping it in the form of pure states.

Published: December 2024

AbstractAccording to the 10th edition of the IDF Diabetes Atlas, 537 million people suffered from diabetes in 2021, and this number will increase by 47% by 2045. It is estimated that even 30–40% of these individuals may develop diabetic kidney disease (DKD) in the course of diabetes. DKD is one of the most important complications of diabetes, both in terms of impact and magnitude. It leads to high morbidity and mortality, which subsequently impacts on quality of life, and it carries a high financial burden. Diabetic kidney disease is considered a complex and heterogeneous entity involving disturbances in vascular, glomerular, podocyte, and tubular function. It would appear that hypoxia-inducible factors (HIF)-1 and HIF-2 may be important players in the pathogenesis of this disease. However, their exact role is still not fully investigated. In this article, we summarize the current knowledge about HIF signaling and its role in DKD. In addition, we focus on the possible effects of nephroprotective drugs on HIF expression and activity in various tissues.

Machine Learning Potential for Serpentines
Authors: Wang Hongjin , Luo Chenxing , Wentzcovitch Renata M. 
Published: December 2024

AbstractSerpentines are layered hydrous magnesium silicates (MgOO) formed through serpentinization, a geochemical process that significantly alters the physical property of the mantle. They are hard to investigate experimentally and computationally due to the complexity of natural serpentine samples and the large number of atoms in the unit cell. We developed a machine learning (ML) potential for serpentine minerals based on density functional theory calculation with the SCAN meta‐GGA functional for molecular dynamics simulation. We illustrate the success of this ML potential model in reproducing the high‐temperature equation of states of several hydrous phases under the Earth's subduction zone conditions, including brucite, lizardite, and antigorite. In addition, we investigate the polysomes of antigorite with periodicity = 13–24, which is believed to be all the naturally existent antigorite species. We found that antigorite with larger than 21 appears more stable than lizardite at low temperatures. This ML potential can be further applied to investigate more complex antigorite superstructures with multiple coexisting periodic waves.

Published: December 2024

AbstractThe large population of HER2-low breast cancer patients necessitates further research to provide enhanced clinical guidance. In this study, we retrospectively analyzed 1071 metastatic breast cancer (MBC) patients and the circulating tumor DNA (ctDNA) to investigate clinicopathological and genetic alterations of HER2-low MBC patients. The effect of HER2-low status on different treatment modalities was explored in two prospective clinical trials (NCT03412383, NCT01917279) and a retrospective study. Our findings suggest TP53, PIK3CA, and ESR1 are frequently mutated genes in HER2-low MBC. Compared to the HER2-0 group, mutations observed in the HER2-low group are more closely associated with metabolic pathway alterations. Additionally, among patients with ERBB2 mutations and treated with pyrotinib, the HER2-low group may experience superior prognosis when compared to the HER2-0 group. Notably, we did not find any statistically significant disparity in the response to chemotherapy, endocrine therapy, or CDK4/6 inhibitor therapy between HER2-0 and HER2-low breast cancer patients. Interestingly, within the subgroup of individuals with metabolic pathway-related gene mutations, we found that HER2-low group exhibited a more favorable response to these treatments compared to HER2-0 group. Additionally, dynamic analysis showed the HER2-low MBC patients whose molecular tumor burden index decreased or achieved early clearance of ctDNA after the initial two treatment cycles, exhibited prolonged survival. Moreover, we classified HER2-low MBC into three clusters, providing a reference for subsequent treatment with enhanced precision. Our study offers valuable insights into the biology of HER2-low MBC and may provide reference for personalized treatment strategies.
