Physician Communication in the Operating Room: Expanding Application of Face Negotiation Theory to the Health Communication Context
Venue: Health communication
Year: 2012

Communication variables that are associated with face negotiation theory were examined in a sample of operating room physicians. A survey was administered to anesthesiologists and surgeons at a teaching hospital in the southwestern United States to measure three variables commonly associated with face negotiation theory: conflict management style, face concern, and self construal. The survey instrument that was administered to physicians includes items that measured these three variables in previous face negotiation research with slight modification of item wording for relevance in the medical setting. The physician data were analyzed using confirmatory factor analysis, Pearson's correlations, and t tests. Results of this initial investigation showed that variables associated with face negotiation theory were evident in the sample physician population. In addition, the correlations were similar among variables in the medical sample as those found in previous face negotiation research. Finally, t tests suggest variance between anesthesiologists and surgeons on specific communication variables. These findings suggest three implications that warrant further investigation with expanded sample size: (1) An intercultural communication theory and instrument can be utilized for health communication research; (2) as applied in a medical context, face negotiation theory can be expanded beyond traditional intercultural communication boundaries; and (3) theoretically based communication structures applied in a medical context could help explain physician miscommunication in the operating room to assist future design of communication training programs for operating room physicians.

Credit Card Fraud Detection Using Autoencoder Neural Network
Venue: ArXiv
Year: 2019

Imbalanced data classification problem has always been a popular topic in the field of machine learning research. In order to balance the samples between majority and minority class. Oversampling algorithm is used to synthesize new minority class samples, but it could bring in noise. Pointing to the noise problems, this paper proposed a denoising autoencoder neural network (DAE) algorithm which can not only oversample minority class sample through misclassification cost, but it can denoise and classify the sampled dataset. Through experiments, compared with the denoising autoencoder neural network (DAE) with oversampling process and traditional fully connected neural networks, the results showed the proposed algorithm improves the classification accuracy of minority class of imbalanced datasets.
DeepTRANS: A Deep Learning System for Public Bus Travel Time Estimation using Traffic Forecasting
Venue: Proc. VLDB Endow.
Year: 2020

In the public transportation domain, accurate estimation of travel times helps to manage rider expectations as well as to provide a powerful tool for transportation agencies to coordinate the public transport vehicles. Although many statistical and machine learning methods have been proposed to estimate travel times, none of the methods consider utilizing predicted traffic information. Forecasting how congestion is going to evolve is critical for accurate travel time estimations. In this paper, we present DeepTRANS, which incorporates traffic forecasting information to our prior Deep Learning based Bus Estimated Time of Arrival (ETA) model, increasing its accuracy by 21% in estimating bus travel time.

Retratos da violencia obstetrica: uma analise sobre a ofensa aos direitos fundamentais no sistema unico de saude
Year: 2018

Este artigo apresenta o problema da violencia obstetrica sob uma perspectiva juridica, norteando se nos atos que violam a integridade fisica e psiquica da mulher e os seus direitos fundamentais. Caracterizando um abuso de genero enraizado na sociedade. A consequencia deste entendimento e que a mulher, na condicao de parturiente, se torna vitima desse tipo de violencia e que diante da inexistencia de uma lei especifica com mecanismos de responsabilizacao, so resta para essas mulheres se valerem de outros meios que possam garantir seus direitos, o que evidencia a morosidade e relativo descompromisso e atraso das autoridades legais brasileiras e seus codigos diante da situacao da assistencia ao parto e nascimento. Os atos violentadores de direito sao reconhecidos independentemente da escolha de parto que a mulher faz. A violencia obstetrica tem como maior problema a naturalizacao dos atos atentatorios, o que muitas vezes impede que ate mesmo a propria vitima se identifique como violentada. O movimento pela humanizacao do parto tem como pontos principais: a) o protagonismo da mulher; b) o apoio a liberdade de escolha e a individualidade da parturiente; c) o uso de procedimentos com respaldo cientifico, com o intuito de reestabelecer o protagonismo da parturiente no momento do parto, garantindo lhe autonomia sobre o proprio corpo, a liberdade e a dignidade da pessoa humana. Os atos violentadores aos direitos fundamentais das parturientes sao constantemente realizados no Sistema Unico de Saude, embora a humanizacao do parto ja tenha uma representacao significativa, ainda sao muitos os casos que violam principios fundamentais. A ideia central e defender os direitos inerentes a todas as mulheres, nao so no trabalho de parto, mas tambem durante o pre e o pos parto.
Detection of vertical muons with the HAWC water Cherenkov detectors and its application to gamma/hadron discrimination
Year: 2017

The HAWC observatory reconstructs atmospheric showers induced by very high energy primary cosmic or gamma rays. Cosmic rays with hadronic nature are several orders of magnitude more frequent than primary gammas and therefore it is necessary to perform the best gamma hadron discrimination for each event to be able to survey the gamma ray sky. Single vertical muons cause very characteristic signals in the 300 HAWC detectors. Particularly, those events that produce signals in the four PMTs of a tank corresponding to muons traversing the tank in the central region. In such cases exist the correlation that the largest signal is also the earliest to arrive, this due to the geometry of the Cherenkov light emission and the fact that relativistic muons travel faster than the light in the medium. This pattern is different from that of electrons, positrons and low energy gammas showering in the first meter of the tank water, which is typical of electromagnetic showers. In this work, we explored whether in air showers it is possible to identify muon signals and whether this can help in the gamma/hadron discrimination of the recorded events.
L'imaginaire post pastorien dans la recherche sur le microbiote intestinal humain
Year: 2017

Alors que la mortalite infectieuse imposait a l'humanite un ineluctable destin epidemique, la revolution scientifique et sociale du XIXe siecle a donne lieu a une veritable revanche sur les micro organismes. Neanmoins, la victoire de la politique d'eradication du monde microbien qui en a decoule est relative non seulement les maladies infectieuses persistent, mais les micro organismes sont parvenus a resister aux traitements destines a les neutraliser. Pire encore, les mesures appliquees pour en venir a bout semblent avoir mis en peril le developpement d'autres micro organismes pourtant necessaires, voire indispensables, a notre bonne sante. Ce constat d'echec tend a etre confirme par les travaux scientifiques recents. Ils demontrent en effet que nous abritons dans notre corps, et surtout dans notre ventre, des millions de microorganismes (le microbiote intestinal) jouant un role crucial dans la digestion et la metabolisation des aliments, le fonctionnement du systeme nerveux central et les fonctions immunitaires. Ce memoire etudie, en mobilisant le cadre theorique des imaginaires sociaux, l'impact de ces decouvertes sur notre imaginaire social du rapport entre l'humain et les micro organismes. En menant des analyses documentaire et bibliometrique, nous montrons dans un premier temps que le domaine de recherche sur le microbiote intestinal est un domaine en voie d'autonomisation, prenant une place de plus en plus importante au sein de la communaute scientifique internationale. Dans un second temps, en analysant le contenu des publications relayant les decouvertes liees au microbiote intestinal, nous mettons en avant l'emergence de deux grands systemes de l'imaginaire social du rapport entre l'humain et les micro organismes les imaginaires pastorien et post pastorien. L'imaginaire pastorien se caracterise par l'ambition de controler, de gerer et d'eradiquer tout micro organisme juge dangereux ou potentiellement dangereux. L'imaginaire post pastorien envisage quant a lui les micro organismes comme de potentiels allies, et appelle a composer avec eux et non contre eux. Une nouvelle vision du monde semble en marche, animee par une volonte de preserver notre ecosysteme en pronant des relations symbiotiques. ______________________________________________________________________________ MOTS CLES DE L'AUTEUR micro organismes humain microbiote intestinal imaginaires sociaux imaginaire pastorien imaginaire post pastorien Science, Technologie et Societe (STS)
Constrained Frequencies: The Wire and the Limits of Listening
Year: 2010

use of music and whose music it uses, from critic Jeff Chang's liner notes for the show's first soundtrack in 2008 to the numerous print and radio interviews with Leyh.2 And the show's music certainly merits this interest: The Wire featured an estimated six hundred separate pieces of music dur ing its five season run.3 Further fueling interest in the show's musical practices was the real life feedback loop that occurred between The Wire and local Baltimore musi cians. While the show prided itself on its attention to the specificities of the local, The Wire rarely included any Baltimore hip hop or house music in any of its scenes during its earliest seasons. Despite this slighting, local musicians and producers eagerly expressed their appreciation for The Wire through their music, culminating in the local release of a series of mixtapes titled Hamsterdam (2005) a nod to the show's third season ex periment in "legal drug trafficking zones." Upon hearing these mixtapes, the show's writers attempted to make amends by both incorporating the work of local musicians into its final two seasons and releasing a second official soundtrack titled Beyond Hamsterdam: Baltimore Traces on "The Wire" (2008) to publicize the Baltimore urban music scene, which, despite some high profile wrangling amongst the pop music literati about its au thenticity and the ethics of its ever eminent, if perpetually delayed, cross over, had never broken through to the mainstream.4 The eventual use of Baltimore based music on the show and its soundtracks, according to Leyh, provided "one more way 'The Wire' [could] give back to Balti "5 more.
An information System for Food Safety Monitoring in Supply Chains based on HACCP, Blockchain and Internet of Things
Year: 2018

With the rapid growth of China's economy, people's living standard has been increased continuously, which changed the consuming habit of consumers, and more and more attention is paid to food safety and quality. However, in recent years, a series of serious food safety incidents occurred, such as "Sudan red" "clenbuterol" "Sanlu toxic milk powder" and "trench oi" It is worth noting that not only in China, but even in Europe these kinds of scandals have broken out during the past 20 years, including Escherichia coliin hamburgers, Salmonella in eggs, poultry and pork, Listeria in pates and cheeses, and the "horse meat scandal" in 2013. These food safety problems not only harm people's health, but also undermine their trust in food markets. The main purpose of this cumulative dissertation is trying to guarantee the food quality and safety from a supply chain management perspective, and the key issue is building a decentralized information system which is not dependent on the trust of a central authority or organization for the whole food supply chain. By using the internet of things and blockchain technologies, this new decentralized information system could become a disruptive innovation which could provide an information platform for all supply chain members (including government departments and third party regulators) based on openness, transparency, neutrality, reliability and security. We want to establish a food supply chain traceability system for real time food tracing, build a safety control system for food supply chain by integrating it with general supply chain risk management methods, and significantly improve the performance of the food logistics company. All of these will ultimately enhance the safety assurance of a food supply chain.
Adsorption and desorption of ammonium by maple wood biochar as a function of oxidation and pH.
Venue: Chemosphere
Year: 2015

The objective of this work was to investigate the retention mechanisms of ammonium in aqueous solution by using progressively oxidized maple wood biochar at different pH values. Hydrogen peroxide was used to oxidize the biochar to pH values ranging from 8.1 to 3.7, with one set being adjusted to a pH of 7 afterwards. Oxidizing the biochars at their lowered pH did not increase their ability to adsorb ammonium. However, neutralizing the oxygen containing surface functional groups on oxidized biochar to pH 7 increased ammonia adsorption two to three fold for biochars originally at pH 3.7 6, but did not change adsorption of biochars oxidized to pH 7 and above. The adsorption characteristics of ammonium are well described by the Freundlich equation. Adsorption was not fully reversible in water, and less than 27% ammonium was desorbed in water in two consecutive steps than previously adsorbed, for biochars with a pH below 7, irrespective of oxidation. Recovery using an extraction with 2M KCl increased from 34% to 99% of ammonium undesorbed by both preceding water extractions with increasing oxidation, largely irrespective of pH adjustment. Unrecovered ammonium in all extractions and residual biochar was negligible at high oxidation, but increased to 39% of initially adsorbed amounts at high pH, likely due to low amounts adsorbed and possible ammonia volatilization losses.
CLINICAL PRACTICE. Polycystic Ovary Syndrome.
Venue: The New England journal of medicine
Year: 2016

A 22 year old woman reports having hirsutism and irregular menses. She describes unpredictable and infrequent menses (five or six per year) since menarche at 11 years of age. Dark, coarse facial hair began to develop at 13 years of age. The symptoms worsened after she gained weight in college. The physical examination includes a body mass index (BMI; the weight in kilograms divided by the square of the height in meters) of 29, blood pressure of 135/85 mm Hg, and moderate hirsutism without virilization. Laboratory tests reveal a total testosterone level of 65 ng per deciliter (2.3 nmol per liter) (assay reference range, 14 to 53 ng per deciliter [0.5 to 1.8 nmol per liter] calculated free testosterone level of 15.3 pg per milliliter (53.1 pmol per liter) (assay reference range, 0.6 to 6.8 pg per milliliter [2.1 to 23.6 pmol per liter] and glycated hemoglobin level of 5.7% (normal value, =5.6% How should this case be evaluated and managed?
Misbehavior, Suspensions, and Security Measures in High School: Racial/Ethnic and Gender Differences
Year: 2013

Author(s) Finn, Jeremy D; Servoss, Timothy  This study used merged data from three national surveys to address questions about security measures in American high schools, suspension rates, and student misbehavior. First, the study identified the characteristics of schools that implemented the most extreme security measures and those with the highest levels of discipline. Second, the study used data on individual students to examine misbehavior and race and gender disparities in suspensions not attributable to misbehavior. The main findings were: (1) In school suspensions serve a 'gateway' function with regard to out of school suspensions. They may provide a time and place to address behavior problems before they escalate or disproportionate out of school suspensions before they occur; (2) Out of school suspensions were more frequent among schools in higher crime neighborhoods. Thus students suspended may be relegated to an environment not conducive to positive educational or social outcomes; (3) African American students and Hispanic/Latino students were suspended at higher rates than were non Hispanic whites, differences in most cases not attributable to different levels of misbehavior; (4) Overall, males were more likely to be suspended than were females, an effect above and beyond that explained by differences in behavior. There was little or no difference in the suspension rates of black males and females, however; (5) High degrees of school security were associated with increased suspension rates and increased black white disparities in total suspensions. At the same time, most black students were enrolled in schools with high degrees of security; (6) Black males were suspended at higher and higher rates as school size increased.All of these have implications for school policy and practice. These are discussed in the paper together with limitations of the investigation.
Silver nanoparticles synthesized by Nigrospora oryzae showed antifungal activity
Venue: Saudi journal of biological sciences
Year: 2021

In this investigation, an alternate green route based on myco synthesised silver nanoparticles (Ag NPs) was evaluated to control plant disease to reduce the usage of synthetic chemicals. Here, we described biologically synthesised Ag NPs using the corn grain contaminant, Nigrospora oryzae, and were well characterised by UV visible spectrophotometer, X ray powder diffraction (XRD) transmission electron microscopy (TEM) Energy Dispersive Spectroscopy (EDS) and particle size analyzer. The pathogenic behaviour of the Fusarium spp. were checked on Giza 86 and Giza 90 cultivars under greenhouse conditions. F. moniliforme and F. oxysporum exhibited high pathogenecity against Giza 90 and Giza 86 cultivars respectively. The antifungal activity of biosynthesised Ag NPs was evaluated against eight species of Fusaria causing damping off of cotton seedlings. In vitro treatments with different concentrations of Ag NPs were achieved on Czapek Dox agar and Potato dextrose agar plates. Fungal growth was drastically retarded from 25 to 200 ppm of Ag NPs interaction. The antifungal activity of Ag NPs against the Fusarium spp. was clearly proven.
Stability analysis of pitch regulated, variable speed wind turbines in closed loop operation using a linear eigenvalue approach
Year: 2008

A multi body aeroelastic design code based on the implementation of the combined aeroelastic beam element is extended to cover closed loop operation conditions of wind turbines. The equations of a controller for variable generator speed and pitch controlled operation in high wind speeds are combined with the aeroelastic equations of motion for the complete wind turbine, in order to provide a compound aeroservoelastic system of equations. The control equations comprise linear differential equations for the pitch and generator torque actuators, the control feedback elements (proportional integral control) and the various filters acting on the feedback signals. In its non linear form, the dynamic equations are integrated in time to provide the reference state, while upon linearization of the system and transformation in the non rotating frame, the linear stability equations are derived. Stability results for a multi MW wind turbine show that the coupling of the controller dynamics with the aeroelastic dynamics of the machine is important and must be taken into account in view of defining the controller parameters.
Video stitching with spatial temporal content preserving warping
Venue: 2015 IEEE Conference on Computer Vision and Pattern Recognition Workshops (CVPRW)
Year: 2015

We propose a novel algorithm for stitching multiple synchronized video streams into a single panoramic video with spatial temporal content preserving warping. Compared to image stitching, video stitching faces several new challenges including temporal coherence, dominate foreground objects moving across views, and camera jittering. To overcome these issues, the proposed algorithm draws upon ideas from recent local warping methods in image stitching and video stabilization. For video frame alignment, we propose spatial temporal local warping, which locally aligns frames from different videos while maintaining the temporal consistency. For aligned video frame composition, we find stitching seams with 3D graphcut on overlapped spatial temporal volumes, where the 3D graph is weighted with object and motion saliency to reduce stitching artifacts. Experimental results show the advantages of the proposed algorithm over several state of the art alternatives, especially in challenging conditions.
