The highly pathogenic avian influenza (H5N2) outbreak in the Midwestern United States (US) in 2015 was historic due to the number of birds and poultry operations impacted and the corresponding economic loss to the poultry industry and was the largest animal health emergency in US history. The U.S. Geological Survey (USGS), with the assistance of several state and federal agencies, aided the response to the outbreak by developing a study to determine the extent of virus transport in the environment. The study goals were to: develop the appropriate sampling methods and protocols for measuring avian influenza virus (AIV) in groundwater, provide the first baseline data on AIV and outbreak- and poultry-related contaminant occurrence and movement into groundwater, and document climatological factors that may have affected both survival and transport of AIV to groundwater during the months of the 2015 outbreak...

A method using rough set feature selection and extreme learning machine (ELM) whose learning strategy and hidden node parameters are optimized by self-adaptive differential evolution (SaDE) algorithm for classification of breast masses is investigated. A pathologically proven database of 140 breast ultrasound images, including 80 benign and 60 malignant, is used for this study. A fast nonlocal means algorithm is applied for speckle noise removal, and multiresolution analysis of undecimated discrete wavelet transform is used for accurate segmentation of breast lesions...

Energy prediction of machine tools can deliver many advantages to a manufacturing enterprise, ranging from energy-efficient process planning to machine tool monitoring. Physics-based, energy prediction models have been proposed in the past to understand the energy usage pattern of a machine tool. However, uncertainties in both the machine and the operating environment make it difficult to predict the energy consumption of the target machine reliably. Taking advantage of the opportunity to collect extensive, contextual, energy-consumption data, we discuss a data-driven approach to develop an energy prediction model of a machine tool in this paper...

OBJECTIVE: Observing experts constitutes an important and common learning experience for surgical residents before operating under direct guidance. However, studies suggest that exclusively observing experts may induce suboptimal motor learning, and watching errors from non-experts performing simple motor tasks may generate better performance. We investigated whether observational learning is transferrable to arthroscopy learning using virtual reality (VR) simulation. SETTING/DESIGN: In our surgical simulation laboratory, we compared students learning basic skills on a VR arthroscopy simulator after watching an expert video demonstration of VR arthroscopy tasks or a non-expert video demonstration of the same tasks to a Control group without video demonstration...

BACKGROUND AND PURPOSE: Motor rehabilitation following stroke is a demanding challenge in search for new strategies to improve outcome. Rehabilitation through action observation has been reported beneficial for older adults recovering from stroke. Early sleep session following motor learning enhanced the performance of the acquired motor skills. The purpose of this study was to examine whether an early sleep session following action observation has benefit over action observation alone in the rehabilitation of older adults after stroke...

Clinical electroencephalographic (EEG) data varies significantly depending on a number of operational conditions (e.g., the type and placement of electrodes, the type of electrical grounding used). This investigation explores the statistical differences present in two different referential montages: Linked Ear (LE) and Averaged Reference (AR). Each of these accounts for approximately 45% of the data in the TUH EEG Corpus. In this study, we explore the impact this variability has on machine learning performance...

AIM: The aim of our study was to describe and assess a new method of mesh fixation using clips in Laparoscopic Ventral Mesh Rectopexy (VMR). This technique avoids knots while suturing in pelvis and saves time. METHOD: A systematic search of the literature (PUBMED, EMBASE) was done to find out alternate ways to fix the mesh over the anterior surface of rectum. This technique has not been used before. We performed five operations using this technique. Indication for surgery was full thickness rectal prolapse in all of them...

Understanding the meaning of abstract mathematical symbols is a cornerstone of arithmetic learning in children. Studies have long focused on the role of spatial intuitions in the processing of numerals. However, it has been argued that such intuitions may also underlie symbols that convey fundamental arithmetic concepts, such as arithmetic operators. In the present cross-sectional study, we used fMRI to investigate how and when associations between arithmetic operators and brain regions processing spatial information emerge in children from 3(rd) to 10(th) grade...

BACKGROUND: Surgeon at primary total hip arthroplasty sometimes cannot achieve sufficient cementless acetabular press-fit fixation and must resort to other fixation methods. Despite a predominant use of cementless cups, this issue is not fully clarified, therefore we performed a large retrospective study to: 1) identify risk factors related to patient or implant or surgeon for unsuccessful intraoperative press-fit, 2) check for correlation between surgeons' volume of operated cases and the press-fit success rate...

PURPOSE: We set out to evaluate how residents in pediatric surgery learn and how they teach. We hypnotized that European residents learn as much from their peers and teach as much as their fellows worldwide, but that they receive comparably less educational training. METHODS: An online questionnaire was distributed to the participants of the combined annual meeting for German, Swiss and Austrian residents in pediatric surgery. Participants were asked whom they learn from in different workplace environments (ward, operating room, emergency department), how, when and why they adopt the role of teacher and how they were prepared for this role...

INTRODUCTION: We sought to apply the principles of human factors research to robotic-assisted radical prostatectomy to understand where training and integration challenges lead to suboptimal and inefficient care. MATERIALS AND METHODS: Thirty-four robotic-assisted radical prostatectomy and bilateral pelvic lymph node dissections over a 20 week period were observed for flow disruptions (FD) - deviations from optimal care that can compromise safety or efficiency. Other variables - physician experience, trainee involvement, robot model (S versus Si), age, body mass index (BMI), and American Society of Anesthesiologists (ASA) physical status - were used to stratify the data and understand the effect of context...

BACKGROUND: Minimally invasive inguinal hernia repair (IHR) in general and particularly in obese patients has not been widely adopted, potentially due to the perceived technical challenges and the well-documented learning curve associated with laparoscopic repair. Outcomes in robotic-assisted IHR in obese (BMI ≥ 30 kg/m(2)) patients have not been described and warrant study. METHODS: Seven surgeons conducted a multicenter retrospective chart review of their early robotic-assisted IHR (RHR) cases and compared them with their open IHR (OHR) cases...
