Xuelian Zang, Zhuanghua Shi, Hermann J Müller, Markus Conci
Learning of spatial inter-item associations can speed up visual search in everyday life, an effect referred to as contextual cueing (Chun & Jiang, 1998). Whereas previous studies investigated contextual cueing primarily using 2D layouts, the current study examined how 3D depth influences contextual learning in visual search. In two experiments, the search items were presented evenly distributed across front and back planes in an initial training session. In the subsequent test session, the search items were either swapped between the front and back planes (Experiment 1) or between the left and right halves (Experiment 2) of the displays...

PURPOSE: Early mobilisation is advocated to improve recovery of intensive care unit (ICU) survivors. However, severe weakness in combination with tubes, lines and machinery are practical barriers for the implementation of ambulation with critically ill patients. The aim of this study was to explore the feasibility of Body Weight-Supported Treadmill Training (BWSTT) in critically ill patients in the ICU. METHODS: A custom build bedside Body Weight-Supported Treadmill was used and evaluated in medical and surgical patients in the ICU...

William Edward Gallie (1882-1959) was a Canadian general surgeon with special expertise in orthopedic surgery. His experience with surgical management of cervical spine subluxation led him to invent a method of cervical wiring of the atlas to the axis. His method of C1-2 wiring has since been modified, but it still remains one of the three most commonly taught wiring techniques in neurosurgical training programs. Gallie is also hailed for instituting the first surgical training program in Canada, a curriculum his pupils memorialized as the "Gallie course" in surgery...

In supervised learning, an inductive learning algorithm extracts general rules from observed training instances, then the rules are applied to test instances. We show that this splitting of training and application arises naturally, in the classical setting, from a simple independence requirement with a physical interpretation of being nonsignaling. Thus, two seemingly different definitions of inductive learning happen to coincide. This follows from the properties of classical information that break down in the quantum setup...

Boson sampling is a problem strongly believed to be intractable for classical computers, but can be naturally solved on a specialized photonic quantum simulator. Here, we implement the first time-bin-encoded boson sampling using a highly indistinguishable (∼94%) single-photon source based on a single quantum-dot-micropillar device. The protocol requires only one single-photon source, two detectors, and a loop-based interferometer for an arbitrary number of photons. The single-photon pulse train is time-bin encoded and deterministically injected into an electrically programmable multimode network...

REVIEW
Kylie Schibli, Kyle Wong, Nina Hedayati, Amedeo D'Angiulli
We review current findings associating socioeconomic status (SES), development of neurocognitive functions, and neurobiological pathways. A sizeable interdisciplinary literature was organized through a bifurcated developmental trajectory (BiDeT) framework, an account of the external and internal variables associated with low SES that may lead to difficulties with attention and learning, along with buffers that may protect against negative outcomes. A consistent neurocognitive finding is that low-SES children attend to information nonselectively, and engage in late filtering out of task-irrelevant information...

Peer support is increasingly provided as a component of mental health care, where people in recovery from mental health problems use their lived experiences to provide support to those experiencing similar difficulties. In the present study, we explored the evolution of peer support workers' (PSW) occupational identities. A qualitative study was undertaken alongside a pilot randomized, controlled trial of peer support for service users discharged from a mental hospital in London, UK. Two focus groups were conducted with eight PSW...

Indoor releases of organic chemicals encapsulated in solid materials are major contributors to human exposures and are directly related to the internal diffusion coefficient in solid materials. Existing correlations to estimate the diffusion coefficient are only valid for a limited number of chemical-material combinations. This paper develops and evaluates a quantitative property-property relationship (QPPR) to predict diffusion coefficients for a wide range of organic chemicals and materials. We first compiled a training dataset of 1103 measured diffusion coefficients for 158 chemicals in 32 consolidated material types...

Ten years after the approval of the Chilean bill that regulates scientific research in humans (Law Nº 20.120), and considering the current status of accreditation and training of many Research Ethics Committee (REC), it is necessary to analyze their performance. We analyzed the Chilean experience with REC aiming to propose a differential type of review, considering the risks to research participants. To improve the quality of the review and the efficiency of these committees, we propose to differentiate the revisions depending on the type of project, its methods and its risks...
