Anna Fitzpatrick, Keith Davids, Joseph A Stone
Manipulating task constraints by scaling key features like space and equipment is considered an effective method for enhancing performance development and refining movement patterns in sport. Despite this, it is currently unclear whether scaled manipulation of task constraints would impact emergent movement behaviours in young children, affording learners opportunities to develop relevant skills. Here, we sought to investigate how scaling task constraints during 8 weeks of mini tennis training shaped backhand stroke development...

The University at Buffalo's neuroendovascular fellowship is one of the longest running fellowship programs in North America. The burgeoning neurointerventional workforce and the rapid growth in the neurointerventional space on the heels of groundbreaking clinical trials prompted us to assess the fellowship's academic impact and its graduates' perceptions and productivity. An anonymized web-based survey was sent to all former neuroendovascular fellows with specific questions pertaining to current practice, research and funding, and perceptions about the fellowship's impact on their skills, competitiveness, and compensation...

BACKGROUND: Recognition of the difficult airway is a critical element of emergency practice. Mallampati score and body mass index (BMI) are not always predictive and they may be unavailable in critically ill patients. Ultrasonography provides high-resolution images that are rapidly obtainable, mobile, and non-invasive. Studies have shown correlation of ultrasound measurements with difficult laryngoscopy; however, none have been performed in the Emergency Department (ED) using a consistent scanning protocol...

To evaluate the variability of multiphase flow properties of porous media at the pore scale, it is necessary to acquire a number of representative samples of the void-solid structure. While modern x-ray computer tomography has made it possible to extract three-dimensional images of the pore space, assessment of the variability in the inherent material properties is often experimentally not feasible. We present a method to reconstruct the solid-void structure of porous media by applying a generative neural network that allows an implicit description of the probability distribution represented by three-dimensional image data sets...

This article presents a new data-driven model design for rendering force responses from elastic tool deformation. The new design incorporates a six-dimensional input describing the initial position of the contact, as well as the state of the tool deformation. The input-output relationship of the model was represented by a radial basis functions network, which was optimized based on training data collected from real tool-surface contact. Since the input space of the model is represented in the local coordinate system of a tool, the model is independent of recording and rendering devices and can be easily deployed to an existing simulator...

This article analyzes the origin of the primary arguments that underpin the qualitative approach, covering the birthplace of comprehensive and dialectical thought in Germany, its expansion into other countries such as France and the United States, and its spread into Latin America. The historical journey of the text starts with the development of modern science, examining the first empirical works in the Chicago School and the subsequent period of ostracism of qualitative research. The text also evidences a revival of comprehensive theoretical and empirical perspectives from the 1960s onwards, accompanying the cultural movement that came to question the great theoretical narratives and give rise to reflections on subjectivity...

Authors have proposed a concept of guidelines for applying the ambulatory complex cardiovascular rehabilitation (ACCVR) into the clinical practice in Slovakia. As a background they have used an actual cardiovascular mortality and morbidity data from home country and abroad as well. They emphasize the non-optimal situation in this aspect which may not be solved by the increasing supporting the invasive revascularization methods and by the intensifying pharmacotherapy only, because the favourable effects of these procedures is timely missing if it is not accompanied by the therapeutic lifestyle changes...

We present a computer program designed to visualize and interact with three-dimensional models of the main anatomical structures of the female pelvis. They are reconstructed from serial sections of corpse, from the Visible Human project of the Medical Library of the United States and from serial sections of high-resolution magnetic resonance. It is possible to represent these three-dimensional structures in any spatial orientation, together with sectional images of corpse and magnetic resonance imaging, in the three planes of space (axial, coronal and sagittal) that facilitates the anatomical understanding and the identification of the set of visceral structures of this body region...

A new solution to the problem of galvanometric laser scanning (GLS) system calibration is presented. Under the machine learning framework, we build a single-hidden layer feedforward neural network (SLFN)to represent the GLS system, which takes the digital control signal at the drives of the GLS system as input and the space vector of the corresponding outgoing laser beam as output. The training data set is obtained with the aid of a moving mechanism and a binocular stereo system. The parameters of the SLFN are efficiently solved in a closed form by using extreme learning machine (ELM)...

BACKGROUND: Compared to 1.5 T, 3 T magnetic resonance imaging (MRI) increases signal-to-noise ratio leading to improved image quality. However, its clinical relevance in clinically isolated syndrome suggestive of multiple sclerosis remains uncertain. OBJECTIVES: The purpose of this study was to investigate how 3 T MRI affects the agreement between raters on lesion detection and diagnosis. METHODS: We selected 30 patients and 10 healthy controls from our ongoing prospective multicentre cohort...

The purpose of the study was to assess the changes in physical fitness performance in young professional soccer players during several training seasons in a Spanish elite reserve team. Physical test values (i.e. vertical jump test, straight line sprint test, and discontinuous and progressive submaximal running test) of 97 young professional soccer players that belonged for at least two consecutive seasons to the reserve team of a Spanish professional team from 1996 to 2013 were analyzed. A distinction was made between the soccer players that were promoted to the Spanish 1/2 Divisions (n = 38) (PFL) and those that were not (n = 59) (non-PFL) (until the end of the 2016/2017 season)...

The idea of "learning in a protected environment" is frequently used within the framework of postgradual education in anaesthesiology. However it remains unclear and its exact meaning lies in the eye of the beholder. This paper aims to highlight the definition of the term "protected environment" and its relevance in anaesthesiology. This includes teaching and learning strategies like competence based training and simulation based training in all its variations. We conclude with an attempt to classify the wide variety of Simulators and teaching methods in use including their individual problems transferred into real life situations...

BACKGROUND/AIM: Within the United Kingdom (UK), physiotherapy preregistration training is provided at both undergraduate and postgraduate level at 17 higher education institutions (HEIs). Some course teams approach this by teaching preregistration BSc and MSc students simultaneously to meet the same learning outcomes. This is often termed "parallel learning" and it is not known how students perceive this mode of learning. The aim of the study was to explore the perceived benefits and challenges to parallel learning of preregistration BSc and MSc physiotherapy students...

Reinforcement learning has been widely used in explaining animal behavior. In reinforcement learning, the agent learns the value of the states in the task, collectively constituting the task state space, and uses the knowledge to choose actions and acquire desired outcomes. It has been proposed that the orbitofrontal cortex (OFC) encodes the task state space during reinforcement learning. However, it is not well understood how the OFC acquires and stores task state information. Here, we propose a neural network model based on reservoir computing...

Mohsen Sharifi, Dan Buzatu, Stephen Harris, Jon Wilkes
BACKGROUND: Blockage of some ion channels and in particular, the hERG (human Ether-a'-go-go-Related Gene) cardiac potassium channel delays cardiac repolarization and can induce arrhythmia. In some cases it leads to a potentially life-threatening arrhythmia known as Torsade de Pointes (TdP). Therefore recognizing drugs with TdP risk is essential. Candidate drugs that are determined not to cause cardiac ion channel blockage are more likely to pass successfully through clinical phases II and III trials (and preclinical work) and not be withdrawn even later from the marketplace due to cardiotoxic effects...
