Scott Feyereisen, Joseph P Broschak, Beth Goodrick
We further our understanding of jurisdictional disputes between established professional groups through a 10-year longitudinal analysis of the differential adoption by U.S. states of policies expanding Certified Registered Nurse Anesthetists' (CRNAs) autonomy. In the United States, CRNAs are trained to deliver anesthetics to patients in the same way as physician anesthesiologists but have more restrictions in practice. Following a 2001 federal decision regarding Medicare reimbursement, states were permitted but not required to allow CRNAs to practice without physician supervision, potentially reducing health care costs...

Machine learning has emerged as an invaluable tool in many research areas. In the present work, we harness this power to predict highly accurate molecular infrared spectra with unprecedented computational efficiency. To account for vibrational anharmonic and dynamical effects - typically neglected by conventional quantum chemistry approaches - we base our machine learning strategy on ab initio molecular dynamics simulations. While these simulations are usually extremely time consuming even for small molecules, we overcome these limitations by leveraging the power of a variety of machine learning techniques, not only accelerating simulations by several orders of magnitude, but also greatly extending the size of systems that can be treated...

Tactual exploration of objects produce specific patterns in the human brain and hence objects can be recognized by analyzing brain signals during tactile exploration. The present work aims at analyzing EEG signals online for recognition of embossed texts by tactual exploration. EEG signals are acquired from the parietal region over the somatosensory cortex of blindfolded healthy subjects while they tactually explored embossed texts, including symbols, numbers, and alphabets. Classifiers based on the principle of supervised learning are trained on the extracted EEG feature space, comprising three features, namely, adaptive autoregressive parameters, Hurst exponents, and power spectral density, to recognize the respective texts...

BACKGROUND: Urinary incontinence (UI), one of the most prevalent health concerns confronting women aged over 60 years, affects up to 55% of older community-dwelling women-20-25% with severe symptoms. Clinical practice guidelines recommend individualized pelvic floor muscle training (PFMT) as a first-line treatment for stress or mixed UI in women, although lack of human and financial resources limits delivery of this first-line treatment. Preliminary data suggest that group-based treatments may provide the answer...

The ability to create power is an important variable for athletic success. No study to date has compared peak power output (PPO) fatigue across multiple sets and with different loads with the bench throw. This study aimed to begin the process of establishing empirical upper body power training guidelines for moderately strong athletes by determining how load (30%, 45%, 60% 1RM) affects PPO (Watts) dropoff during 3 sets of 10 repetitions of the bench throw. 10 resistance-trained male volunteers ((mean ± SD): age 20...

Distress is highly prevalent in cancer survivors, from the point of diagnosis through treatment and recovery, with rates higher than 45% reported worldwide. One approach for helping people cope with the inherent stress of cancer is through the use of mind-body therapies (MBTs) such as mediation, yoga, hypnosis, relaxation, and imagery, which harness the power of the mind to affect physical and psychological symptoms. One group of MBTs with a growing body of research evidence to support their efficacy focus on training in mindfulness meditation; these are collectively known as mindfulness-based interventions (MBIs)...

BACKGROUND: Tick populations and tick-borne infections have steadily increased since the mid-1990s posing an ever-increasing risk to public health. Yet, modelling tick dynamics remains challenging because of the lack of data and knowledge on this complex phenomenon. Here we present an approach to model and map tick dynamics using volunteered data. This approach is illustrated with 9 years of data collected by a group of trained volunteers who sampled active questing ticks (AQT) on a monthly basis and for 15 locations in the Netherlands...

BACKGROUND AND PURPOSE: A growing body of literature substantiates that Tai Chi is a form of exercise that may help older adults increase strength, improve balance, lower fall rates, and experience less fear of falling. Few studies, however, offer controlled experimental design and simultaneously investigate multiple factors known to contribute to fall risk. The purpose of this study was to compare performance on measures relating to fall risk (strength, balance, functional mobility, and fear of falling) in older community-dwelling adults who participated in a community-based Tai Chi program with a control group of their peers who had no Tai Chi training over the same time period...

BACKGROUND: In a typical electrophysiological experiment, especially one that includes studying animal behavior, the data collected normally contain spikes, local field potentials, behavioral responses and other associated data. In order to obtain informative results, the data must be analyzed simultaneously with the experimental settings. However, most open-source toolboxes currently available for data analysis were developed to handle only a portion of the data and did not take into account the sorting of experimental conditions...
