OBJECTIVES: A virtual-reality training program has been developed to help older pedestrians make safer street-crossing decisions in two-way traffic situations. The aim was to develop a small-scale affordable and transportable simulation device that allowed transferring effects to a full-scale device involving actual walking. METHODS: 20 younger adults and 40 older participants first participated in a pre-test phase to assess their street crossings using both full-scale and small-scale simulation devices...

Transcranial direct current stimulation (tDCS) is a promising tool for neurocognitive enhancement. Several studies have shown that just a single session of tDCS over the left dorsolateral pFC (lDLPFC) can improve the core cognitive function of working memory (WM) in healthy adults. Yet, recent studies combining multiple sessions of anodal tDCS over lDLPFC with verbal WM training did not observe additional benefits of tDCS in subsequent stimulation sessions nor transfer of benefits to novel WM tasks posttraining...

The purpose of this study is to evaluate transfer learning with deep convolutional neural networks for the classification of abdominal ultrasound images. Grayscale images from 185 consecutive clinical abdominal ultrasound studies were categorized into 11 categories based on the text annotation specified by the technologist for the image. Cropped images were rescaled to 256 × 256 resolution and randomized, with 4094 images from 136 studies constituting the training set, and 1423 images from 49 studies constituting the test set...

REVIEW
Thierry Paillard
This review addresses the possible structural and functional adaptations of the postural function to motor experience. Evidence suggests that postural performance and strategy evolve after training in inactive subjects. In trained subjects, postural adaptations could also occur, since elite athletes exhibit better postural performance than, and different postural strategy to sub-elite athletes. The postural adaptations induced are specific to the context in which the physical activity is practiced. They appear to be so specific that there would be no or only a very slight effect of transfer to non-experienced motor tasks (apart from in subjects presenting low initial levels of postural performance, such as aged subjects)...

BACKGROUND: Preventing urgent intubation and upgrade in level of care in patients with subclinical deterioration could be of great utility in hospitalized patients. Early detection should result in decreased mortality, duration of stay, and/or resource use. The goal of this study was to externally validate a previously developed, vital sign-based, intensive care unit, respiratory instability model on a separate population, intermediate care patients. METHODS: From May 2014 to May 2016, the model calculated relative risk of adverse events every 15 minutes (n = 373,271 observations) for 2,050 patients in a surgical intermediate care unit...

Zhengming Ding, Yun Fu
Metric learning has attracted increasing attention due to its critical role in image analysis and classification. Conventional metric learning always assumes the training and test data are sampled from the same or similar distribution. However, to build an effective distance metric, we need abundant supervised knowledge (i.e., side/label information), which is generally inaccessible in practice because of the expensive labeling cost. In this paper, we develop a Robust Transfer Metric Learning (RTML) framework to effectively assist the unlabeled target learning by transferring the knowledge from the well-labeled source domain...

Visual display solutions are a key element of computer-based system architectures intended for human-system interaction. Particularly in the training domain, an ill-matched visual display can render a system unusable or ineffectual, which may cause underutilization or a negative transfer of training. This article outlines a set of approaches and best practices used in research efforts focused on the design of novel military training systems.

TOPIC: Despite the substantial amount of money invested in staff training each year, many people trained fail to transfer what they learn to the workplace. We document a training initiative that was implemented to develop and maintain a competent workforce. PURPOSE: A work-based learning (WBL) model was used as a guide to teach the knowledge and skills necessary to effectively deliver psychiatric rehabilitation services. SOURCES USED: This training framework afforded practitioners an opportunity to acquire the critical knowledge and skills to improve the quality of life for individuals living with serious mental illnesses...

DongKyu Lee, Sohyun Han, HyungJoon Cho
A variable repetition-delay (TR) spin echo sequence with repeated refocusing pulses, i.e., a variable TR turbo-spin echo (TSE), provides an attractive means of acquiring an accurate T1 map information that is free from gradient echo based artifacts such as magnetic field inhomogeneities particularly for ultra-high field (at 7T and above) preclinical applications. However, the applicability of multi-slice TSE sequences is often limited by signal distortion from T2 relaxation due to echo-train acquisitions for short T2 tissues, inter-slice cross talks and magnetization transfer (MT) from repetitive slice-selective 180° pulse, and extended scan times with multiple TR excitations...

Accurate classification of human aquatic activities using radar has a variety of potential applications such as rescue operations and border patrols. Nevertheless, the classification of activities on water using radar has not been extensively studied, unlike the case on dry ground, due to its unique challenge. Namely, not only is the radar cross section of a human on water small, but the micro-Doppler signatures are much noisier due to water drops and waves. In this paper, we first investigate whether discriminative signatures could be obtained for activities on water through a simulation study...

We investigated transfer of the skills developed by competitive Scrabble players. Previous studies reported superior performance for Scrabble experts on the lexical decision task (LDT), suggesting near transfer of Scrabble skills. Here we investigated the potential for far transfer to a symbol decision task (SDT); in particular, transfer of enhanced long-term working memory for vertically presented stimuli. Our behavioral results showed no evidence for far transfer. Despite years of intensive practice, Scrabble experts were no faster and no more accurate than controls in the SDT...

BACKGROUND: Critical illness myopathy (CIM) and polyneuropathy (CIP) are a common complication of critical illness. Both cause intensive-care-unit-acquired (ICU-acquired) muscle weakness (ICUAW) which increases morbidity and delays rehabilitation and recovery of activities of daily living such as walking ability. Focused physical rehabilitation of people with ICUAW is, therefore, of great importance at both an individual and a societal level. A recent systematic Cochrane review found no randomised controlled trials (RCT), and thus no supporting evidence, for physical rehabilitation interventions for people with defined CIP and CIM to improve activities of daily living...

PRIMARY OBJECTIVE: Repetition-lag memory training was developed to increase individuals' use of recollection as opposed to familiarity in recognition memory. The goals of this study were to examine the feasibility of repetition-lag training in patients with chronic stroke and to explore whether the training might show suggestions of transfer to non-trained tasks. RESEARCH DESIGN: Quasi-experimental. METHODS AND PROCEDURES: Patients (n = 17) took part in six repetition-lag training sessions and their gains on the training and non-trained tasks were compared to those of age-matched healthy controls (n = 30)...

Accidental administration of non-epidural drugs into the epidural or subarachnoid spaces may be associated with unexpected pain, morbidity, adverse effects, increased level of care, prolonged hospital stay, and mortality. We describe a 12-month-old admitted for secondary-stage hypospadias reconstruction. General anesthesia was induced with sevofiurane and a peripheral catheter was placed. Instead of ropivacaine, rocuronium (80 mg; 6.3 mg/kg) was injected into the epidural space by the caudal route. Surgery was uneventful and was completed 160 minutes after rocuronium was given...

The only curative approach in pancreatic ductal adenocarcinoma (PDAC) is resection, which is possible only in 15 - 30 % of patients. Local tumor spread or distant metastases are contraindications for resection in the majority of patients. Surgical-oncological quality with short- and long-term results are varying tremendously, so that "expertise/quality" are associated to hospital- or surgeon's volume and/or center formation. The treatment results also depend, to a great extent, on the medical diagnostic quality...

Visual perceptual grouping, the process of forming global percepts from discrete elements, is experience-dependent. Here we show that the learning time course in an animal model of artificial vision is predicted primarily from the density of visual elements. Three naïve adult non-human primates were tasked with recognizing the letters of the Roman alphabet presented at variable size and visualized through patterns of discrete visual elements, specifically, simulated phosphenes mimicking a thalamic visual prosthesis...

The cerebellum has been shown to be important for skill learning, including the learning of motor sequences. We investigated whether cerebellar transcranial direct current stimulation (tDCS) would enhance learning of fine motor sequences. Because the ability to generalize or transfer to novel task variations or circumstances is a crucial goal of real world training, we also examined the effect of tDCS on performance of novel sequences after training. In Study 1, participants received either anodal, cathodal or sham stimulation while simultaneously practising three eight-element key press sequences in a non-repeating, interleaved order...
