Fully Integrated, Stretchable, Wireless Skin‐Conformal Bioelectronics for Continuous Stress Monitoring in Daily Life

Stress is one of the main causes that increase the risk of serious health problems. Recent wearable devices have been used to monitor stress levels via electrodermal activities on the skin. Although many biosensors provide adequate sensing performance, they still rely on uncomfortable, partially flexible systems with rigid electronics. These devices are mounted on either fingers or palms, which hinders a continuous signal monitoring. A fully‐integrated, stretchable, wireless skin‐conformal bioelectronic (referred to as “SKINTRONICS”) is introduced here that integrates soft, multi‐layered, nanomembrane sensors and electronics for continuous and portable stress monitoring in daily life. The all‐in‐one SKINTRONICS is ultrathin, highly soft, and lightweight, which overall offers an ergonomic and conformal lamination on the skin. Stretchable nanomembrane electrodes and a digital temperature sensor enable highly sensitive monitoring of galvanic skin response (GSR) and temperature. A set of comprehensive signal processing, computational modeling, and experimental study provides key aspects of device design, fabrication, and optimal placing location. Simultaneous comparison with two commercial stress monitors captures the enhanced performance of SKINTRONICS in long‐term wearability, minimal noise, and skin compatibility. In vivo demonstration of continuous stress monitoring in daily life reveals the unique capability of the soft device as a real‐world applicable stress monitor.
How authors cite references? A study of characteristics of in‐text citations

How to differentiate citations is continuously an important research question of citation analysis. Recently, some researchers analyze full‐text academic articles with tools and techniques of natural language processing to find out the characteristics of in‐text citations. In this study, we analyze 4,255 articles published during 2007 to 2016 to explore how authors of library and information science (LIS) cite references in their articles. The pattern of citations shows that LIS authors cite more works on average but the average in‐text citation times per reference in an article only increase slightly in this period. There are more in‐text citations in the first quarter fraction of an article and the number of in‐text citations decrease gradually with text progression. The distribution of POS shows that when LIS authors mention references in text body, they use more noun, verb, and preposition than less adjective and adverb. We also choose the high frequency words of different POS to investigate which words authors prefer in in‐text citations. In these high frequency words, nouns tend to be about research topics. Verbs are neutral or used to describe methods or findings of these cited works. As to adjective and adverb, most of them are positive or neutral. But there are more negative words in adverb.
Análisis de dependencias entre refactorings para solucionar code smells

Los code smells son síntomas en el código fuente que pueden revelar problemas de diseño. Para poder solucionar un smell deben aplicarse un conjunto de refactorings que permitan restructurar el sistema. Sin embargo, al aplicar un conjunto de refactorings en un orden determinado, pueden surgir problemas que impiden que éstos se apliquen. Por ejemplo, porque un refactoring que depende de una reestructuración realizada por otro refactoring que aún no fue aplicado, o porque un refactoring referencia un artefacto del sistema que fue modificado por un refactoring aplicado anteriormente. Por estos motivos, para aplicar un conjunto de refactorings, se deben analizar las dependencias que existen entre estos para poder establecer el orden de aplicación. En esta línea, este trabajo presenta una herramienta que identifica y soluciona los conflictos originados por dependencias entre refactorings para luego aplicar automáticamente los mismos. Los resultados, si bien son preliminares, indican que este enfoque permite identificar y solucionar un alto porcentaje de conflictos.
Awareness and Perceptions on Health Warning Labels on Cigarette Packs among Smokers: A Cross-Sectional Study

Backgrounds Tobacco use is the leading preventable cause of premature deaths. Tobacco control remains a top priority, and health warning labels (HWLs) are one of the recommended methods. This study is aimed at examining the awareness and perceptions of HWLs on cigarette packs among smokers. Methods A cross-sectional study was conducted among 240 smokers who were randomly recruited from three townships in Mandalay in 2018. A face-to-face interview was done using a questionnaire. Multivariate logistic regression was used to analyse the data. Results About half were 18-40 years old; the majority were males (96.3%) and smokers (93.4%). Nearly all respondents noticed both pictorial warning and text messages, and about half could identify the current size of HWLs. Most of the smokers generally had positive perceptions and opinions on HWLS, and they strongly supported it. About 75% intended to reduce the number of cigarettes, and 18% were willing to quit within 6 months. Those who desired to reduce the number of cigarettes were more likely to quit within 6 months (aOR = 7.6, 95% CI 1.6-35.9 and aOR = 19.6, 95% CI 13.0-294.7 for those who had a little and strong desire, respectively). Conclusion Awareness status and perceptions of the respondents were acceptable, and HWLs have motivated smokers to quit smoking. The Tobacco Control Program needs to strengthen the tobacco control law that prohibits selling loosies in order to maximize the benefits of HWLs.
Noteworthy Neurological Manifestations Associated With COVID-19 Infection

March 11, 2020 marked the start of the coronavirus disease 2019 (COVID-19) pandemic. COVID-19, caused by severe acute respiratory syndrome coronavirus 2, was being reported as a severe respiratory illness. However, since the recognition of this novel virus, there has been a constant realization that it may present or manifest in a multitude of ways. At first, the typical signs and symptoms were what one would expect from a respiratory virus: cough, shortness of breath, and fever. However, as the disease became more prevalent, neurologic symptoms were reported such as headaches, hypogeusia, and hyposmia. This case report aims to add to the growing body of neurologic manifestations by presenting two cases, Bell’s palsy and Guillain-Barre syndrome. Each case involves flaccid paralysis as the primary presentation.
An Experimental Massive MIMO Channel Matrix Model for Hand-Held Scenarios

A novel, experimental massive channel matrix model for indoor scenarios is proposed. In this model, the hand-held effects of smartphone users are taken into consideration, as well as the correlation and coupling at transmitters and receivers in the conventional models. Hence, the proposed model is more applicable in real environments. Measurements at 3.5 GHz are carried out in a typical indoor scenario with a massive multiple-input multiple-output (MIMO) testbed to serve as a base station and an eight-antenna handset to mimic a smartphone. Channel performance predicted by the proposed model is in good agreement with the measurement results. It is highlighted that the proposed model is more accurate than the traditional massive MIMO channel matrix models.
THERMAL RESISTANCE OF ANTIBIOTIC‐RESISTANT AND ANTIBIOTIC‐SENSITIVE SALMONELLA SPP. ON CHICKEN MEAT

The aim of this research was to investigate the potential relationship, if any, between the acquisition/possession of antibiotic resistance genes in strains of Salmonella and its resistance to heat stress. Chicken pieces were inoculated with antibiotic sensitive (AS) strains of S. Enteritidis and S. Typhimurium, its laboratory-acquired antibiotic-resistant (AR) mutant strains (nalidixic acid and streptomycin), or a multiresistant strain of S. Typhimurium DT104. Half of these samples were heat-shocked (48C for 30 min) and all were heat-challenged at 55C for up to 30 min. Samples were then plated on xylose lysine desoxycholate (XLD) and tryptone soya agar (TSA) overpoured with XLD. Heat-shocked cultures of S. Typhimurium DT104 had significantly higher D-values (the time required for a 1 log reduction in the number of bacteria) than their non-heat-shocked counterparts (P < 0.05). No significant differences were observed between AR and their AS. However, the D-values for S. Typhimurium DT104 were significantly higher than the D-values for S. Typhimurium (AS) and S. Enteritidis (AS) (P < 0.05). This study concluded that laboratory-acquired antibiotic-resistant mutation did not affect heat resistance of the Salmonella strains studied and suggested a potential link between multiantibiotic resistance and heat resistance in S. Typhimurium DT104.
An Evaluation of Early Warning Models for Systemic Banking Crises: Does Machine Learning Improve Predictions?

This paper compares the out-of-sample predictive performance of different early warning models for systemic banking crises using a sample of advanced economies covering the past 45 years. We compare a benchmark logit approach to several machine learning approaches recently proposed in the literature. We find that while machine learning methods often attain a very high in-sample fit, they are outperformed by the logit approach in recursive out-of-sample evaluations. This result is robust to the choice of performance measure, crisis definition, preference parameter, and sample length, as well as to using different sets of variables and data transformations. Thus, our paper suggests that further enhancements to machine learning early warning models are needed before they are able to offer a substantial value-added for predicting systemic banking crises. Conventional logit models appear to use the available information already fairly efficiently, and would for instance have been able to predict the 2007/2008 financial crisis out-of-sample for many countries. In line with economic intuition, these models identify credit expansions, asset price booms and external imbalances as key predictors of systemic banking crises.
IL-7-induced proliferation of peripheral Th17 cells is impaired in HAART-controlled HIV infection

Objectives: Th17 cells are key regulators of functional immunity in mucosal tissues, including the gut-associated lymphoid tissue (GALT), an important site of immune impairment in HIV infection. During HIV infection, Th17 cells are lost in large numbers from the GALT. Despite the recovery of peripheral CD4+ T cells that accompanies suppression of viral replication with HAART, Th17 cells in GALT are not completely restored. IL-7 is essential for the survival and proliferation of T cells, but its signaling through its receptor IL-7R&agr; (CD127), is impaired in CD8+ T cells and thymocytes during HIV infection. We set out to determine if decreased CD127 expression or impaired CD127 signaling may be the cause of Th17 impairment in HAART-controlled HIV infection. Design: Healthy and HIV+ donors on HAART were selected for this study of Th17 cell function in HIV. Methods: Peripheral CD4+ T cells and Th17 cells were isolated using magnetic beads, then stimulated with IL-7. CD127 expression and the phosphorylation of signaling molecules was determined using flow cytometry. Proliferation was determined with a CFSE dilution assay. Results: CD127 was not decreased on Th17 cells from HAART-controlled HIV+ individuals, in fact, the percentage of Th17 cells that express CD127 was increased in treated HIV+ individuals. Furthermore, Th17 cells from HAART-controlled individuals, have normal IL-7-induced STAT5 and Bcl-2 responses, but vastly decreased proliferative responses. Conclusion: This reduced IL-7 responsiveness may explain the lack of Th17 cell recovery and ongoing systemic immune activation that persists despite well treated HIV infection.
Entwurf miniaturisierter Antennengruppen

Abstract The present thesis is concerned with the design of compact antenna arrays. The terms "compact" and "miniaturised" are used interchangeably for antenna arrays where the element separation is smaller than the conventional lambda/2 distance. Ultimately, the goal is to make more efficient use of the frequency spectrum by improving the diversity capabilities of the antenna arrays used. Theoretical and practical limits of antenna array miniaturisation are discussed. The physical phenomenon of superdirectivity is examined, which accounts for the strong coupling seen between closely spaced antenna elements. An analysis of the physical limits based on spherical harmonics reveals that six orthogonal polarisation modes exist even in the case of electrically very small arrays. Properly exploiting these degrees of freedom can therefore lead to an improved performance of compact antenna array designs. It is found that an antenna array is optimally described in terms of its overall eigenmode efficiencies. Eigenmodes can be interpreted as an orthogonal basis for radiation. Practical examples demonstrate that eigenmode matching as well as the eigenmode quality factors are suitable measures for the successful optimisation of compact antenna arrays. The major contribution of this work is the development of a new design method for decoupling and matching networks. Decoupling and matching networks counteract gain reductions caused by reflections due to eigenmode mismatch. The new method takes advantage of all degrees of freedom available for network design. Furthermore, effects of network losses are taken into account during the design procedure. For the first time it is demonstrated how a set of desired port beam patterns can be orthogonalised and subsequently realised as part of a decoupling and matching network. Methods for reducing network complexity and optimising network element tolerances are introduced, which make practical implementations feasible. Diversity gain improvements due to the decoupling and matching network are shown to reach between two and three decibels. Another question addressed in this work deals with the advantages and disadvantages associated with different network realisations. Theoretically, the specific set of orthogonal beam patterns is shown to be of secondary concern. More important is minimisation of ohmic losses as well as parasitic energies stored within the network.
Diversity of rhizosphere bacteria associated with different soybean cultivars in two soil conditions

Abstract Aiming at learning the effects of soil conditions and cultivar on the bacterial diversity in the rhizosphere of soybean (Glycine max(L.) Merr. ), bacterial communities associated with four soybean cultivars grown in two soils were revealed by terminal-restriction fragment length polymorphism (T-RFLP) combined with sequencing analysis of a 16S rDNA clone library. Lower bacteria diversity was found in soil A which has higher salinity and nutrient contents, while the highest bacterial diversity was found in the rhizosphere of cv. Jidou 12 in both soils. These results revealed that both the soil conditions and soybean cultivar affected the community composition of rhizosphere bacteria, but the effect of soil conditions was greater than that of soybean cultivar as demonstrated by the principal component analysis. It also revealed that the abundant rhizosphere bacteria may also the main symbiotic or non-symbiotic nodule endophytes.
Online Public Shaming on Twitter: Detection, Analysis, and Mitigation

Public shaming in online social networks and related online public forums like Twitter has been increasing in recent years. These events are known to have a devastating impact on the victim’s social, political, and financial life. Notwithstanding its known ill effects, little has been done in popular online social media to remedy this, often by the excuse of large volume and diversity of such comments and, therefore, unfeasible number of human moderators required to achieve the task. In this paper, we automate the task of public shaming detection in Twitter from the perspective of victims and explore primarily two aspects, namely, events and shamers. Shaming tweets are categorized into six types: abusive, comparison, passing judgment, religious/ethnic, sarcasm/joke, and whataboutery, and each tweet is classified into one of these types or as nonshaming. It is observed that out of all the participating users who post comments in a particular shaming event, majority of them are likely to shame the victim. Interestingly, it is also the shamers whose follower counts increase faster than that of the nonshamers in Twitter. Finally, based on categorization and classification of shaming tweets, a web application called BlockShame has been designed and deployed for on-the-fly muting/blocking of shamers attacking a victim on the Twitter.

Execution of SPE code in an Opteron-Cell/B.E. hybrid system

It is a great research interest to integrate the Cell/B.E. processor into an AMD Opteron system. The result is a system benefiting from the advantages of both processors: the high computational power of the Cell/B.E. and the high I/O throughput of the Opteron. The task of this diploma thesis is to accomplish, that Cell-SPU code initially residing on the Opteron could be executed on the Cell under the GNU/Linux operating system. However, the SPUFS (Synergistic Processing Unit File System), provided from STI (Sony, Toshiba, IBM), does exactly the same thing on the Cell. The Cell is a combination of a PowerPC core and Synergistic Processing elements (SPE). The main work is to analyze the SPUFS and migrate it to the Opteron System. The result of the migration is a project called RSPUFS (Remote Synergistic Processing Unit File System), which provides nearly the same interface as SPUFS on the Cell side. The differences are caused by the TCP/IP link between Opteron and Cell, where no Remote Direct Memory Access (RDMA) is available. So it is not possible to write synchronously to the local store of the SPEs. The synchronization occurs implicitly before executing the Cell-SPU code. But not only semantics have changed: to access the XDR memory RSPUFS extends SPUFS with a special XDR interface, where the application can map the XDR into the local address space. The application must be aware of synchronization with an explicit call of the provided ”xdr sync” routine. Another difference is, that RSPUFS does not support the gang principle of SPUFS, which is necessary to set the affinity between the SPEs. This thesis deals not only with the operating system part, but also with a library called ”libspe”. Libspe provides a wrapper around the SPUFS system calls. It is essential to port this library to the Opteron, because most of the Cell applications use it. Libspe is not only a wrapper, it saves a lot of work for the developer as well, like loading the Cell-SPU code or managing the context and system calls initiated by the SPE. Thus it has to be ported, too. The result of the work is, that an application can link against the modified libspe on the Opteron gaining direct access to the Synergistic Processor Elements.
Evolving fixed-parameter tractable algorithms

One effective means of computing NP-hard problems is provided by fixed-parameter tractable (fpt-) algorithms. An fpt-algorithm is an algorithm whose running time is polynomial in the input size and superpolynomial only as a function of an input parameter. Provided that the parameter is small enough, an fpt-algorithm runs fast even for large inputs. In this paper, we report on an investigation of the evolvability of fpt-algorithms via Genetic Programming (GP). The problem used in this investigation is the NP-hard 2D-Euclidean Traveling Salesman Problem (TSP), which is known to be fpt if the number of points not on the convex hull is taken as the parameter. The algorithm evolved in our GP study turns out to have clear characteristics of an fpt-algorithm. The results suggest GP can be utilized for generating fpt-algorithms for NP-hard problems in general, as well as for discovering input parameters that could be used to develop fpt-algorithms.
Regional ventilation characteristics during non-invasive respiratory support in preterm infants

Objectives To determine the regional ventilation characteristics during non-invasive ventilation (NIV) in stable preterm infants. The secondary aim was to explore the relationship between indicators of ventilation homogeneity and other clinical measures of respiratory status. Design Prospective observational study. Setting Two tertiary neonatal intensive care units. Patients Forty stable preterm infants born <30 weeks of gestation receiving either continuous positive airway pressure (n=32) or high-flow nasal cannulae (n=8) at least 24 hours after extubation at time of study. Interventions Continuous electrical impedance tomography imaging of regional ventilation during 60 min of quiet breathing on clinician-determined non-invasive settings. Main outcome measures Gravity-dependent and right–left centre of ventilation (CoV), percentage of whole lung tidal volume (VT) by lung region and percentage of lung unventilated were determined for 120 artefact-free breaths/infant (4770 breaths included). Oxygen saturation, heart and respiratory rates were also measured. Results Ventilation was greater in the right lung (mean 69.1 (SD 14.9)%) total VT and the gravity-non-dependent (ND) lung; ideal–actual CoV 1.4 (4.5)%. The central third of the lung received the most VT, followed by the non-dependent and dependent regions (p<0.0001 repeated-measure analysis of variance). Ventilation inhomogeneity was associated with worse peripheral capillary oxygen saturation (SpO2)/fraction of inspired oxygen (FiO2) (p=0.031, r2 0.12; linear regression). In those infants that later developed bronchopulmonary dysplasia (n=25), SpO2/FiO2 was worse and non-dependent ventilation inhomogeneity was greater than in those that did not (both p<0.05, t-test Welch correction). Conclusions There is high breath-by-breath variability in regional ventilation patterns during NIV in preterm infants. Ventilation favoured the ND lung, with ventilation inhomogeneity associated with worse oxygenation.
Effects of pyriproxyfen on ovarian development and fecundity of Rhagoletis pomonella flies

Three‐day old female apple maggot flies, Rhagoletis pomonella (Walsh), were topically exposed to different doses (0.1, 1, 10, and 100 μg per fly) of a juvenile hormone mimic, pyriproxyfen, in the laboratory. Pyriproxyfen had little lethal effect on females except at the extremely high dose of 100 μg. It also had no significant effect on egg viability of treated females. A non‐lethal dose of 1 μg per fly did, however, enhance significantly the fecundity (egg production) as well as the ovarian development (number of eggs in ovaries and length of egg folicles) of treated flies. We conclude that pyriproxyfen could be a useful aid in exploring endocrine regulation of feeding and reproductive physiology behavior in R. pomonella, about which current knowledge is scant.
