Perioperative management and optimization of atrial fibrillation for noncardiac surgery

Perioperative AF is a common problem that frequently forces surgeons and anesthesiologists to make difficult decisions before and on the day of planned surgeries. There is controversy regarding how to characterize andmanage patients with AF in the perioperative period often due to confusion regarding the differences in the classifications of AF, the various characteristics of AF, and differing approaches to perioperative and long-term management. We attempt to bring clarity to evaluating and managing perioperative AF. Currently, AF prevalence is cited as more than 5 million, and estimated to increase to 12.1 million by 2030. New-onset AF within 2 to 4 days after noncardiac surgery ranges from 10% to20% of noncardiac thoracic cases and 0.5% to 15% of noncardiac, nonthoracic cases. There are important associated risks including increased mortality and morbidity associated with stroke, heart and renal failure, and bleeding, among others. The financial cost of perioperative AF management is best measured in the assessment of lost revenue and increased health care resources. According to a 2011 study, unnecessary cancellation or postponement of procedures and excessive costs equaled 6 to 26 billion US$ in the late 2000s. Considering the increasing incidence and prevalence of AF in the aging population, there is a clear need to standardize the perioperative management of AF to reverse the upward trend.
Statistical analysis on a case study of load effect on PSD technique for induction motor broken rotor bar fault detection

Broken rotor bars in an induction motor create asymmetries and result in abnormal amplitude of the sidebands around the fundamental supply frequency and its harmonics. Monitoring the power spectral density (PSD) amplitudes of the motor currents at these frequencies can be used to detect the existence of broken rotor bar faults. This paper presents a study on an actual three-phase induction motor using the PSD analysis as a broken rotor bar fault detection technique. The distributions of PSD amplitudes of experimental healthy and faulty motor data sets at these specific frequencies are analyzed statistically under different load conditions. Results indicate that statistically significant conclusions on broken rotor bar detection can vary significantly under different load conditions and under different inspected frequencies. Detection performance in terms of the variation of PSD amplitudes is also investigated as a case study.
The Correlation between Carotid Intima-Media Thickness and Neutrophil to Lymphocyte Ratio in Prediabetes Patients

Background Prediabetes is a metabolic state between normoglycemia and diabetes and is known to carry a higher risk of developing overt diabetes and cardiovascular disease (CVD). The relative and absolute risks of all-cause mortality, CVD, coronary heart disease, and stroke in prediabetes patients, as well as in diabetic patients, is higher than that in patients with normoglycemia. Carotid intima-media thickness (cIMT) is a method used to stratify CVD risk. In this study, we aimed to determine whether the neutrophil-to-lymphocyte ratio (NLR) correlates with cIMT in prediabetes patients. Methods From January 1, 2016, to February 20, 2021, 581 adults their 30s–70s who underwent carotid ultrasonography as part of a comprehensive medical examination at the Dongtan Sacred Heart Hospital were enrolled. Statistical analysis using SPSS presented t-test and chi-square test significance levels into a group with normal cIMT (nIMT; cIMT <1 mm) and a group with thick cIMT (tIMT; cIMT ≥1 mm). Binary logistic regression analysis was performed to confirm the correlation between NLR and cIMT. Results In prediabetic adults, age, hemoglobin A1c (HbA1c), systolic blood pressure, and NLR were significantly higher in the tIMT group than in the nIMT group. In the regression analysis, NLR, age, and HbA1c were significantly correlated with cIMT. Conclusion NLR was significantly higher in the tIMT group than in the nIMT group; therefore, NLR may be used to assess CVD risk in prediabetes patients.
Effect of Gender Differences in Reading Habits of University Students in Sri Lanka

Reading habits of university students, which is crucial in building a robust individual, are affected by various factors. This study was conducted to explore the effect of gender differences in reading habits of university undergraduates in Sri Lanka. Data were obtained using a questionnaire from 192 male and 474 female students of six universities. Enjoying reading, reading preferences, how often they are reading and reading frequency showed significant variations between the two genders (p<0.05). Female students enjoyed reading and spent more time in reading than their male counterparts. Most female students preferred novels (28.5%), while male respondents (7.5%) selected books to read. Both male (14.5%) and female (33.1%) students selected education as their preferred genre while politics and poetry were preferred by least number of female students (6.6%) and male students (2.1%) respectively. Personal satisfaction was the main reason for reading to both the male (17.4%) and female students (39.9%) while the least number of male (2.1%) and female (7.2%) students read for reinforcing their lessons. The majority of the female students responded that preparation for exams (39.6%) was the main barrier against reading, while male students selected social networks (16.5%). In terms of frequency, the majority of the girls (19.5%) read once a week, while 9.3% of boys read less frequently, whereas 0.9% of them never read. Based on this study, female are better in reading than male students in Sri Lankan universities.
Distinct histone H3–H4 binding modes of sNASP reveal the basis for cooperation and competition of histone chaperones

In this study, Liu et al. investigated how sNASP binds H3–H4 in the presence and absence of ASF1, two major histone H3–H4 chaperones found in distinct and common complexes, during chromosomal duplication. They show that, in the presence of ASF1, sNASP principally recognizes a partially unfolded Nα region of histone H3, and in the absence of ASF1, an additional sNASP binding site becomes available in the core domain of the H3–H4 complex, providing new mechanistic insights into coordinated histone binding and transfer by histone chaperones.
Racial and Socioeconomic Disparities in Out-Of-Hospital Cardiac Arrest Outcomes: Artificial Intelligence-Augmented Propensity Score and Geospatial Cohort Analysis of 3,952 Patients

Introduction Social disparities in out-of-hospital cardiac arrest (OHCA) outcomes are preventable, costly, and unjust. We sought to perform the first large artificial intelligence- (AI-) guided statistical and geographic information system (GIS) analysis of a multiyear and multisite cohort for OHCA outcomes (incidence and poor neurological disposition). Method We conducted a retrospective cohort analysis of a prospectively collected multicenter dataset of adult patients who sequentially presented to Houston metro area hospitals from 01/01/07-01/01/16. Then AI-based machine learning (backward propagation neural network) augmented multivariable regression and GIS heat mapping were performed. Results Of 3,952 OHCA patients across 38 hospitals, African Americans were the most likely to suffer OHCA despite representing a significantly lower percentage of the population (42.6 versus 22.8%; p < 0.001). Compared to Caucasians, they were significantly more likely to have poor neurological disposition (OR 2.21, 95%CI 1.25–3.92; p=0.006) and be discharged to a facility instead of home (OR 1.39, 95%CI 1.05–1.85; p=0.023). Compared to the safety net hospital system primarily serving poorer African Americans, the university hospital serving primarily higher income commercially and Medicare insured patients had the lowest odds of death (OR 0.45, p < 0.001). Each additional $10,000 above median household income was associated with a decrease in the total number of cardiac arrests per zip code by 2.86 (95%CI -4.26- -1.46; p < 0.001); zip codes with a median income above $54,600 versus the federal poverty level had 14.62 fewer arrests (p < 0.001). GIS maps showed convergence of the greater density of poor neurologic outcome cases and greater density of poorer African American residences. Conclusion This large, longitudinal AI-guided analysis statistically and geographically identifies racial and socioeconomic disparities in OHCA outcomes in a way that may allow targeted medical and public health coordinated efforts to improve clinical, cost, and social equity outcomes.
Bandwidth‐enhanced internal PIFA with a coupling feed for quad‐band operation in the mobile phone

A novel bandwidth‐enhanced internal planar inverted‐F antenna (PIFA) for quad‐band operation in the mobile phone is presented. The proposed PIFA is capacitively excited using a coupling feed, which leads to a dual‐resonance excitation in the antenna's lower band at about 900 MHz and a wide‐band resonant mode excitation at about 1800 MHz. This makes the operating bandwidths of both the antenna's lower and upper bands larger than 20% (3:1 VSWR), thus easily covering GSM850/900 and DCS/PCS operation. In addition, with quad‐band operation obtained, the proposed PIFA occupies a small volume of 5 × 6 × 60 mm3 or 1.8 cm3 only. Details of the proposed PIFA are described, and results of fabricated prototypes are presented and discussed. © 2008 Wiley Periodicals, Inc.

Formal Verification of MILS Partition Scheduling Module Using Layered Methods

—MILS partition scheduling module ensures isolation of data between different domains completely by enforcing secure strategies. Although small in size, it involves complicated data structures and algorithms that make monolithic verification of the scheduling module difficult using traditional verification logic (e.g., separation logic). In this paper, we simplify the verification task by dividing data representation and data operation into different layers and then to link them together by composing a series of abstraction layers. The layered method also supports function calls from higher implementation layers into lower abstraction layers, allowing us to ignore implementation details in the lower implementation layers. Using this methodology, we have verified a realistic MILS partition scheduling module that can schedule operating systems (Ubuntu 14.04, VxWorks 6.8 and RTEMS 11.0) located in different domains. The entire verification has been mechanized in the Coq Proof Assistant.
Impact of Body Mass Index on Major Complications, Multiple Complications, In-hospital Mortality, and Failure to Rescue After Esophagectomy for Esophageal Cancer

Objective: To examine the association of BMI with mortality and related outcomes after oncologic esophagectomy. Summary Background Data: Previous studies showed that high BMI was a risk factor for anastomotic leakage and low BMI was a risk factor for respiratory complications after esophagectomy. However, the association between BMI and in-hospital mortality after oncologic esophagectomy remains unclear. Methods: Data for patients who underwent esophagectomy for esophageal cancer between July 2010 and March 2019 were extracted from a Japanese nationwide inpatient database. Multivariate regression analyses and restricted cubic spline analyses were used to investigate the associations between BMI and short-term outcomes, adjusting for potential confounders. Results: Among 39,406 eligible patients, in-hospital mortality, major complications, and multiple complications (≥2 major complications) occurred in 1069 (2.7%), 14,824 (37.6%), and 3621 (9.2%), respectively. Compared with normal weight (18.5–22.9 kg/m2), severe underweight (<16.0 kg/m2), mild/moderate underweight (16.0–18.4 kg/m2), and obese (≥27.5 kg/m2)were significantly associated with higher in-hospital mortality [odds ratio 2.20 (95% confidence interval 1.65–2.94), 1.25 (1.01–1.49), and 1.48 (1.05–2.09), respectively]. BMI showed U-shaped dose-response associations with mortality, major complications, and multiple complications. BMI also showed a reverse J-shaped association with failure to rescue (death after major complications). Conclusions: Both high BMI and low BMI were associated with mortality, major complications and multiple complications after esophagectomy for esophageal cancer. Patients with low BMI were more likely to die once a major complication occurred. The present results can assist with risk stratification in patients undergoing oncologic esophagectomy.
Trajectory tracking of an underactuated fixed-wing UAV

This paper presents a solution to the problem of trajectory tracking for a fixed-wing UAV. With its inherent actuator constraints, a fixed-wing UAV is not able to track an arbitrary trajectory, such that a guidance scheme is required in order to solve the trajectory tracking problem. In this paper, this is solved by first designing a virtual saturated control law that makes the position and velocity errors go to zero. Then the outputs from the virtual control law are mapped onto actuated variables that can be tracked using the available actuators. To that end, a model-based proportional speed controller and a quaternion-based sliding surface controller are presented, making all the errors go to zero. The solution is proved using Lyapunov theory and is validated through simulations where a fixed-wing UAV tracks a circular trajectory.
Evaluating the Feasibility and Efficacy of a Pediatric Intensive Care Unit Diary

As the progress of critical care medicine has improved the survival rate of critically ill patients, comorbidities and long-term health care have attracted people's attention. The terms “post–intensive care syndrome” (PICS) and “PICS-family” (PICS-F) have been used in non-neurocritical care populations, which are characterized by the cognitive, psychiatric, and physical sequelae associated with intensive care hospitalization of survivors and their families. An intensive care unit (ICU) diary authored by the patient's family members may alleviate the psychological distress of the patient and his or her family. This quality improvement project focused on the development and implementation of the pediatric intensive care unit (PICU) diary in the pediatric critical care setting. The project aims to evaluate the feasibility and the potential efficacy of the PICU diary, measured through parental acceptance and satisfaction. Seventeen families of critically ill children admitted to the PICU received the PICU diary during the implementation period. Twenty-four parents completed the weekly follow-up, and 15 subsequently completed the diary entry evaluation. The use of the diary in the PICU setting is feasible and considered beneficial by families of critically ill children.
Electrochemical nanobiosensors perspectives for COVID 19 pandemic

Early, rapid and ultrasensitive diagnosis of COVID-19 to facilitate high-throughput analysis without a high degree of technical expertise or sophisticated equipment is necessary to expand COVID-19 testing capability. Leveraging interdisciplinary proficiency in analytical chemistry, biomedical instrumentation, molecular biology, microfluidics, and nanotechnology, considerable advances have been made to develop a novel diagnostic tool that assures superior key performances for COVID-19 diagnosis. This review summarizes the nano-enabled systems such as electrochemical nanobiosensor for SARS-CoV-2 virus detection and emphasizes promising diagnostic techniques to extensively facilitate the diagnostic practices during the COVID-19 pandemic. Currently, three main diagnostic methods have been widely used in the COVID-19 pandemic: nucleic acid (NA)-based testing, computed tomography (CT), and serological testing. NA-based detection of SARS-CoV-2 such as Reverse transcription polymerase chain reaction has become the gold standard for COVID-19 diagnosis. This review congregates significant contributions in the electrochemical nanobiosensor research area, which is helpful for further nanobiosensor development. Although many efforts were taken to detect the SARS-CoV-2, the COVID 19 diagnosis still relies on expensive prolonged analysis. A rapid and reliable alternative is the utilization of a low-cost nanobiosensor for SARS-CoV-2 detection that can rapidly diagnose the disease even in asymptomatic conditions with high reliability and sensitivity.
Gender-affinity voting in legislative elections under open-list proportional representation rules: the legislative elections in Chile in 2017

ABSTRACT In most democracies, women are a majority in the electorate, but men are the majority of those elected. Previous studies on gender affinity voting that point to substantive, descriptive and symbolic representation are often based on polling date and focus on whether women issues were central in the election. Since electoral rules—including candidate gender quotas—impact the choices voters have, we use a novel database with precinct-level voting data for 960 candidates (397 women) in the 28 open-list proportional representation districts for the 2017 Chamber of Deputies election in Chile to identify the determinants of gender affinity voting for candidates in same party matchups and whether gender affinity voting differently impacted left and rightwing parties. Using 35,120 precincts, we analyze 1,344,098 data points for individual candidates’ vote shares. We find statistically significant, but not substantive, gender affinity voting, especially favorable to women candidates in leftwing parties.
Losses on Multiconductor Transmission Lines in Multilayered Dielectric Media

For the transmission-line modes, a multiconductor transmission line in a multilayered dielectric medium can be characterized by four matrix parameters the capacitance matrices [C], the inductance matrix [L], the shunt conductance matrix [G], and the series resistance matrix [R]. The first two matrices [C] and [L] can be obtained from equivalent electrostatic and magnetostatic problems. The conductance matrix [G] can be obtained by changing all dielectric constants epsilon/sub i/ to complex dielectric constants /angle over epsilon/sub i/ in the equivalent electrostatic problem. The resistance matrix [R] can be obtained by applying a perturbation method to each mode of the transmission line. A computer program has been written for an arbitrary line, and sample computations are presented.
UNDERSTANDING ENGLISH LANGUAGE TEACHERS’ VIEWS OF TEACHER RESEARCH: A REPORT FROM INDONESIA

This article reports on a study investigating the perceptions of EFL teachers in schools and language courses (henceforth, teachers) and EFL lecturers in tertiary educational institutions (academic staff) from Indonesia regarding their definitions of and their engagements in teacher research. An online questionnaire was used to gather quantitative data from almost 400 EFL teachers and academic staff from Indonesia. The questionnaire was followed by in-depth interviews with some respondents who met the criteria set and agreed to be interviewed. Results from the study show that both teachers and academic staff align research with evidence-based practice, survey, literature-driven practice and professional communication, and observation-based popular article. In terms of engagements, most of the teachers and academic staff read research papers occasionally, and more academic staff did research compared to teachers. Research done by both teachers and academic staff is largely associated with internal and external factors, such as, professional awareness and professional obligation, with academic staff seem to receive more support to engage in research. The findings of the study provide insights for future continuous professional development (CPD) activities for English teachers and academic staff. The activities might involve exploring ways to integrate teacher research into teachers’ and academic staff’s teaching responsibilities and integrating teacher research into the short-term and long-term goals of CPD.
Modes of Knowledge Accumulation, Entry Regimes and Patterns of Industrial Evolution

In this work we explore the interplay between entry, selection and innovative learning as determinants of industrial evolution. We propose a model aimed to capture the essential features of learning and competition as drivers of the dynamics. Using both analytical and numerical techniques, we are able to disentangle possible generic properties which robustly hold for a wide range of parameterization. In particular, we identify different generic ``evolutionary archetypes'' in turn defined by characteristic interactions between entry/exit regimes, learning and industrial structures.
Modification of District Integrated Administrative Services (PATEN) and Super Service Delivery Models at Polewali Mandar

In order to realize the demands of the community in service, the government will seek several things to improve the quality of services provided by bringing up a policy. To produce a quality policy requires good cooperation by the local government. Improving public services to optimize services in the regions can be done by reforming the administration at a level that is directly dealing with the community, namely at the sub-district level and implementing innovation. The innovation in question is the sub-district integrated administrative service system (PATEN). PATEN is held with the aim of realizing the sub-district as a community service center and becoming a service node for the one-stop integrated service agency/office (PTSP) in the district for sub-districts whose geographical area will be more effectively and efficiently served through the sub-district. With a qualitative method, this research on the implementation of PATEN in Polewali Mandar was studied based on the concepts of communication, resources, disposition, and bureaucratic structure. Obstacles encountered in communication due to limitations in providing patent services to the public during the covid 19 pandemic, PATEN service providers were provided with training, related to disposition, clearer supervision standards were needed regarding the use and supervision of budgets by districts so that achievements and obstacles could be evaluated on a regular basis ; and simplification of standard operating procedures on aspects of bureaucratic structure.
METHOD FOR ANALYSING THE RISK OF OVERUSE INJURY IN GYMNASTICS

The purpose of this study was to propose and assess a method for the evaluation of all loads experienced during gymnastics training. The method is based on the measurement of acceleration on the gymnast. Twelve gymnasts performed a range of gymnastics skills with an impact component. Ground reaction forces and acceleration at the pelvis were measured. There were significant correlations between peak GRF and peak acceleration during landing from gymnastics skills for individual participants. This testing showed the potential for this method to be applied in a study of injury risk factors outside the laboratory environment. At present, this relationship means that acceleration can be used as an estimation of force, after calibrating acceleration to ground reaction force for the individual.
