System level thermal design-process modeling for functional/structure design using SysML and MDM

The conventional thermal design process for consumer electronics focusing exclusively on hardware is becoming insufficient for limiting thermal risk in the market. This study uses system modeling language (SysML) and a multiple- domain matrix (MDM) to examine the thermal design process at the system level, which comprises both hardware and software. The entire thermal design process is visualized using an MDM comprising design structure matrices for the function, performance, and structure of a product and the correlations between them. It is demonstrated through the trade-off study of image processor selection and a machine design that our proposed thermal design process can lead better product specifications in terms of thermal performance and parts cost.
The Effectiveness of Placement Exams and a Free Remedial Summer Program at a Midsized Selective Private University

In order to explore the effectiveness of MSSPU’s remedial placement practices and the impacts of participation in the Free Remedial Summer Program on student outcomes, this ex post facto study examined performance in remedial courses, persistence to graduation, and time to graduation as it relates to mathematics and English composition placement level, high school grade point averages, entrance exam scores, and participation in the Free Remedial Summer Program. Five unique statistical tests were utilized to address fifteen hypothesis related to seven research questions. Several major findings were a result of this study. First, students who complete the mathematics placement exam and enroll outside of their recommended level, either above or below their placement level, perform better in both their first and second mathematics courses, on average, than those who enroll at the recommended level. The same was found for English composition. Second, students who place at a non-remedial level are more likely to persist to graduation, statistically. Third, neither high school grade point average nor entrance exam scores alone are strong indicators of time or persistence to graduation. However, fourth, the factors of high school grade point average, entrance exam score, and placement exam performance may be a better indicator of persistence to graduation when analyzed in a combined fashion. Finally, students who enroll in the Free Remedial Summer Program are less likely to persist to graduation than those who enroll in remedial coursework as part of their first term. These students also are more likely to fail their first and subsequent mathematics courses. This study concludes with a brief analysis of implications for practice, recommendations for further research, and a review of best practices.
Improved chipless tag based on multifilters

In this study, a novel compact chipless RFID transponder is presented. The coding information is based on spectral signature using three types of multiresonator: spiral, slot, and U‐shaped defected ground structure (DGS). Each resonator can be seen as a band‐stop filter which contributes to a particular resonance frequency. The previous spiral resonator based barcodes have only 1 bit information on each resonator which result in a large quantity of resonators relatively and a long microstrip line. In our design, the slot is cutting on the spiral resonator so more bits can be stored. The combination of slot and spiral resonators together provides an efficient decrease in resonator numbers. The DGS structure takes use of ground plane of the tag which further increases the capacity without expanding the size. The method of using these three types of resonators presents a clear improvement in miniaturizing the transponder which leads to a compact size of the tag. By applying frequency shift coding (FSC) coding technique, a coding density of 0.946 bit/cm2 is achieved. Improvement in two cross‐polarized transmitting and receiving antennas is also considered in the design. Corresponding experiments on realized prototypes are provided to validate the effectiveness of the proposed design.
Korea's Response to COVID-19 According to Set Time Frames, With a Focus on the Network Between the Government and Responding Agencies: Social Network Analysis

Background In December 2019, COVID-19 was first confirmed in Wuhan, China, and as the respiratory disease spread around the globe, there was a spike in interest worldwide in combating such contagious diseases. When such disasters occur, the central government of South Korea and its affiliated local governments—together with nongovernmental organizations—play a crucial role in crisis management systems. Objective The purpose of this paper is to corroborate the characteristics government ministries and domestic and foreign institutions exhibit through their interconnection when the parties are undergoing a disease-related catastrophe such as the COVID-19 pandemic. Methods Using the social network analysis technique, the span of the COVID-19 pandemic was segmented into 3 time frames, and the relational characteristics of the COVID-19 contagious disease response department and related agencies at home and abroad were analyzed based on 3 centralities. Results Evidence from the second and third time frames indicates that the agents reacting to contagious diseases do not necessarily hold the central position in the network. From this, it can be inferred that it is not only the primary host that plays a pivotal role but the key to a successful response to various disasters also lies in cooperation with the relevant parties. Conclusions The incongruency between the findings of this paper and the existing disaster response system gives rise to the corollary that both the essential parties and the adjoining ones need to collaborate for a coordinated crisis response in disaster situations. Furthermore, much significance lies in the fact that this paper explores the various aspects that could surface among the host and relevant parties in a real-life pandemic.
A Framework for Implementing Information and Communication Technologies in Agricultural Development in Maharashtra

Knowledge is an increasingly significant factor of production in modern agriculture. Information and Communication Technologies (ICTs) can accelerate agricultural development by facilitating knowledge management. Based on an evaluation of several ICT initiatives in rural Maharashtra, a framework to guide policy and implementation of ICTs in state agriculture is proposed. In this framework, agricultural development is visualized from two perspectives, rural incomes and livelihoods perspective at the farm level, and a sustainability perspective at the regional level. The implementation of ICTs is proposed in three unique institutional environments: (i) closed vertical supply chain network for agribusiness enterprises, (ii) an open chain network with dynamically evolving partners and supply chain situations for the public, non-governmental and multilateral organizations, and (iii) a spatial data services network to address natural resources management and sustainability concerns. Each environment is assessed to identify its appropriate business models centered around ICTs, required technologies, scope for up-scaling the models, and required institutional and policy initiatives. In the future, as ICT infrastructure grows and connectivity and hardware costs decline, the critical constraints are likely to be the development of appropriate policy and institutional environments for the creation and delivery of information and knowledge to the end users. Significant policy, institutional networking and capacity building initiatives will be required at various levels to overcome the constraints and effectively integrate ICTs into the agricultural development process in Maharashtra.
Proceedings of ICOeV2015, International Conference on Engineering Vibration

Hand-held impact machines have been used since the early 20th century. Up to day still a little has been changed in their fundamental design. Despite them being robust and effi-cient, vibration, noise, dust and poor ergonomics cause a large number of injuries to the op-erators, especially in the stone industry. In this paper, vibration dynamics of a pneumatic hand-held impact machine (HHIM) equipped with a nonlinear tuned vibration absorber (NLTVA) is in focus. The considered HHIM has the same parameters as the existing conven-tional one with respect to piston weight, impact energy and operating frequency. The paper presents the mathematical and computational models of vibration dynamics of the HHIM with NLTVA as well as the experimental set-up developed for model validation. The advantage of using a nonlinear spring is shown and how the effective vibration reduction frequency of the NLTVA can be made to follow the excitation frequency and thereby in principal achieving the same conditions as is the case for tuned pendulum absorbers for torsional vibrations where the resonance frequency follows the engine order. Using the verified and validated computational model, the sensitivity analysis of vibration dynamics has been performed in a broad set of feasible operational scenarios with respect to structural parameters of the HHIM equipped with NLTVA. Sensitivity analysis results have formed the base for optimisation of the parameters of NLTVA. It was shown by simulations as well as it was proved by experiment that the vibration of the HHIM equipped with NLTVA can be reduced significantly in a broader range of operating frequencies compared to the vibration of the same machine equipped with linear tuned vibration absorber. The results obtained confirm the possibility to design a user friendly impact machine efficiently operating in a broad frequency range. Optimised NLTVA combined with vibration isolation has shown to significantly the on

Enlivening the Waterfront: Crime prevention through design

This paper proposed a theoretical design principle to enlivening waterfront space planning for crime prevention. Waterfront is usually the focal point of urban or port activity and became the symbiosis between water-related and urban-based functions. Increasing reports on crime problem have caused design, planning and development of waterfronts to be challenging and contentious. This study involved qualitative method and observation to Lumut Waterfront in Perak, Malaysia. Design approaches were identified based on crime prevention through environmental design (CPTED). Characteristics and criteria of CPTED were adapted to emphasise on public safety. It may be costly, but safety is more important. © 2016. The Authors.

In the Midst of a Pandemic, Introverts May Have a Mortality Advantage

Extroverts may enjoy lower mortality than introverts under normal circumstances, but the relationship may be different during an airborne pandemic when social contact can be deadly. We used data for midlife Americans surveyed in 1995-96 with mortality follow-up through December 31, 2020 to investigate whether the association between extroversion and mortality changed during the COVID-19 pandemic. We hypothesized that excess mortality during the pandemic will be greater for extroverts than for introverts. Results were based on a Cox model estimating age-specific mortality controlling for sex, race/ethnicity, the period trend in mortality, and an additional indicator for the pandemic period (Mar-Dec 2020). We interacted extroversion with the pandemic indicator to test whether the relationship differed between prepandemic and pandemic periods. Prior to the pandemic, extroversion was associated with somewhat lower mortality (HR=0.93 per SD, 95% CI 0.88-0.97), but the relationship reversed during the pandemic: extroverted individuals appeared to suffer higher mortality than their introverted counterparts, although the effect was not significant (HR=1.20 per SD, 95% CI 0.93-1.54). Extroversion was associated with greater pandemic related excess mortality (HR=1.20/0.93=1.29 per SD, 95% CI 1.00-1.67). Compared with someone who scored at the mean level of extroversion, mortality rates prior to the pandemic were 10% lower for a person who was very extroverted (i.e., top 12% of the sample at Wave 1), while they were 12% higher for someone who was very introverted (i.e., 11th percentile). In contrast, mortality rates during the pandemic appeared to be higher for very extroverted individuals (HR=1.15, 95% CI 0.77-1.71) and lower for those who were very introverted (HR=0.70, 95% CI 0.43-1.14) although the difference was not significant because of limited statistical power. In sum, the slight mortality advantage enjoyed by extroverts prior to the pandemic disappeared during the first 10 months of the COVID-19 pandemic. It remains to be seen whether that pattern continued into 2021-22. We suspect that the mortality benefit of introversion during the pandemic is largely a result of reduced exposure to the risk of infection, but it may also derive in part from the ability of introverts to adapt more easily to reduced social interaction without engaging in self-destructive behavior (e.g., drug and alcohol abuse). Introverts have been training for a pandemic their whole lives.
Behavioral responses to fevers and other medical events in children with and without ASD

Anecdotal reports and a small number of research studies suggest possible behavioral improvements in children with autism spectrum disorders (ASD) during a fever. However, previous studies rely largely on retrospective reports of this phenomenon. Establishing a robust association between fever and reduction of ASD‐related symptoms would promote opportunities for the development of innovative therapeutic interventions for children with ASD. In the current study, prospective data were collected from 141 children with ASD and 103 typically developing (TD) controls using parent responses to an 11‐item behavioral survey. Behaviors when no illness was present, during a fever, the week after a fever, and during non‐febrile illnesses for TD and ASD children were compared. Profiles of cases in which caregivers reported consistent behavioral improvements during fever are described. Data indicated worsening social, emotional/behavioral, and somatic symptoms during a fever regardless of diagnosis, with children with ASD demonstrating greater worsening of behaviors during a fever than TD children. Only three out of 141 children with ASD demonstrated consistent behavioral improvements during a fever; these children had a range of cognitive and adaptive skills. Children with ASD had stronger negative responses to fever than TD children. These findings contradict previous literature suggesting behavioral improvements for children with ASD. While improvements may occur for some children, it does not appear to be a common phenomenon. Additional research is needed to elucidate the nature of behavioral improvements in the subset of children with ASD who may respond positively to fever.
Clearing the Fog: A Systematic Review on Cognitive Dysfunction in COVID-19

Objective: The systematic review aims to examine the association between COVID-19 and cognitive dysfunction, including the link between the severity of COVID-19 and the occurrence of cognitive impairment and the potential pathophysiological mechanisms related to brain fog among COVID-19 patients. Methods: PubMed, Oxford University Press, ProQuest Health and Medical Complete, ScienceDirect, Ovid, HERDIN, Google Scholar, and Cochrane Library databases were accessed to retrieve literature using the PRISMA guidelines. Results: After critical appraisal, thirteen full journal articles were included in the study. The studies showed the most frequent cognitive impairment are attention, memory, and executive function in COVID-19 patients. Compared with healthy controls (HC) in 3 out of 4 studies, cognitive impairment was only evident in COVID-19 patients. Furthermore, two studies showed no correlation between brain fog and depression, and five studies showed a link between the severity of COVID-19 infection and cognitive impairment. Cases ranging from mild to severe illness presented manifestations of brain fog. However, a disparity in the evidence of the pathophysiology of COVID-19 and cognitive dysfunction exists, prompting the need to investigate further. Additionally, recent studies provide insufficient evidence for direct central nervous system invasion, and there are emerging studies that contrast the presumed pathogenesis of neurological complications from neuroinflammation. Conclusion: There is an association between COVID-19 and cognitive dysfunction. Manifestation of cognitive dysfunction is present regardless of illness severity. Moreover, there are existing pathophysiological mechanisms of the Coronavirus that lead to cognitive dysfunction in COVID-19 patients; however, additional studies are required to substantiate such mechanisms further.
Tuberous sclerosis complex‐associated nonfunctional pancreatic neuroendocrine tumors: Management and surgical outcomes

We aimed to further characterize pancreatic involvement in tuberous sclerosis complex (TSC), with a focus on management of TSC‐associated nonfunctional pancreatic neuroendocrine tumors (PNETs). This was a retrospective chart review of a large cohort of TSC patients. A total of 637 patients with a confirmed diagnosis of TSC were seen at the Herscot Center for Tuberous Sclerosis Complex at Massachusetts General Hospital. Of the 637 total patients with a confirmed diagnosis of TSC, 28 patients were found to have varying pancreatic findings ranging from simple‐appearing cysts to well‐differentiated PNETs. Thirteen of the 28 patients had PNET confirmed on pathology; 10 of these tumors were resected at Massachusetts General Hospital. None of the patients had serious perioperative or postoperative complications; only one of the patients had a recurrence following resection. As roughly 4.4% of our TSC patient population had pancreatic involvement, surveillance abdominal imaging should include evaluation of the pancreas instead of limiting to a renal protocol. Additionally, given the low risk of complications and recurrence combined with documented risk of metastasis in TSC‐associated PNET, TSC patients with pancreatic lesions suspicious for PNETs should be considered as surgical candidates.
Health Care Professionals' Perspectives on the Uses of Patient-Generated Health Data

Integration of digital self-management solutions into health care processes requires the involvement of health care professionals in the adoption and use of the solutions as part of the care pathway. We conducted 23 interviews with diverse profiles of health care professionals participating in the treatment of chronic patients in three different countries. Our results indicate that health care professionals appeared relatively motivated at the prospect of having access to patient-generated data. Nevertheless, they appeared less confident in weighing what types of data could be collected efficiently through mobile devices and how it could be presented in ways that would provide value to the care process. Our results identify four broad categories for how patient-generated health data could be useful: monitoring, prevention, research, and transparency of condition parameters.
Bacteriophage therapy of human‐restricted Salmonella species—a study in a surrogate bacterial and animal model

Salmonella Typhi has been an important human‐restricted pathogen from time immemorial, and unfortunately, the indiscriminate use of antibiotics has induced the emergence of multidrug resistance in S. Typhi. Bacteriophage therapy may be a possible alternative in countering antimicrobial resistance. Therefore, this study was planned to assess the efficacy of bacteriophages in treating acute and chronic S. Typhimurium infection in the mouse as a surrogate model. We isolated bacteriophages against S. Typhimurium and selected three different bacteriophages for the in vivo experiments. The lethal dose of S. Typhimurium was decided for Swiss albino mice, and acute infection was developed. Further, bacteriophage therapy by daily intraperitoneal injection of phage cocktail was given for 14 days. While the chronic carrier state of S. Typhimurium in Swiss albino mice was developed by inoculating intraperitoneally sequential 10‐fold increasing doses of the bacterium. On the successful establishment of carrier state, oral feeding of phage cocktail at a high count was given, which completely cured the carrier state within 7 days of feeding. These experiments confirmed that the phage cocktail could eradicate the S. Typhimurium from the mice in both types of infections, that is acute and chronic.
Why is diagnosis, investigation, and improved management of kidney stone disease important? Non-pharmacological and pharmacological treatments for nephrolithiasis

ABSTRACT Introduction Progress in the medical treatment and management of nephrolithiasis has been limited to date and continues to depend on urinary metabolic screening to assess excretion of the main stone constituents, factors determining stone solubility and precipitation, and on dietary and lifestyle recommendations. Areas covered In this review, we try to highlight some of the broader aspects of kidney stone disease in relation to recent epidemiological and pathophysiological findings, and emerging new treatments. Specifically, this review will cover recent evidence on the association between metabolic risk factors and kidney stone disease, dietary risk factors, and dietary interventions to prevent kidney stones, and how genomics, metabolomics, and proteomics may improve diagnosis and treatment of this troublesome, if rarely fatal, condition. PubMed was used to identify the most suitable references according to our search strategy; only full manuscripts were included. Expert opinion What is emerging is that kidney stone disease is not an isolated disorder but is systemic in nature with links to important and common comorbidities such as diabetes, hypertension, cardiovascular disease, and chronic kidney disease. These associations support the need to take nephrolithiasis seriously as a medical condition and to adopt a more holistic approach to its investigation and treatment.
