The deployment density and computational power of small base stations (BSs) are expected to increase significantly in the next generation mobile communication networks. These BSs form the mobile edge network, which is a pervasive and distributed infrastructure that can empower a variety of edge/fog computing applications. This paper proposes a novel edge-computing application called explicit caching, which stores selective contents at BSs and exposes such contents to local users for interactive browsing and download...

Keratoconus is an idiopathic, non-inflammatory and degenerative corneal disease characterised by a loss of the organisation in the corneal collagen fibrils. As a result, keratoconic corneas present a localised thinning and conical protrusion with irregular astigmatism and high myopia that worsen visual acuity. Intracorneal ring segments (ICRSs) are used in clinic to regularise the corneal surface and to prevent the disease from progressing. Unfortunately, the post-surgical effect of the ICRS is not explicitly accounted beforehand...

Gender-based discrimination and bias are widespread in professional settings, including academic medicine. Overt manifestations such as sexual harassment have long been identified but attention is only more recently turning towards subtler forms of bias, including inequity in promotion and compensation. Barriers to progress vary across institutions and include lack of awareness, inadequate training, poor informational transparency, and challenging power dynamics. We propose five solutions that the academic medical community can adopt to not only name, but also address, gender-based bias as the proverbial elephant in the room: definitively identify the systemic nature of the problem, prompt those with influence and power to advance a culture of equity, broadly incorporate evidence-based explicit anti-sexist training, increase transparency of information related to professional development and compensation, and use robust research methods to study the drivers and potential solutions of gender inequity within academic medicine...

Purpose: Primary lacrimal canaliculitis (PLC) is a unique disorder which often gets misdiagnosed by the general as well as speciality-trained ophthalmologists. Elderly patients with history of chronic or recurrent epiphora with discharge, often get mislead towards chronic dacryocystitis. The aim of our report is to discuss the misleading diseases in our PLC patients and to revisit this hidden disease. Methods: The patients of PLC who were previously misdiagnosed were studied...

It is undisputed that presenting a rhythmic stimulus leads to a measurable brain response that follows the rhythmic structure of this stimulus. What is still debated, however, is the question whether this brain response exclusively reflects a regular repetition of evoked responses, or whether it also includes entrained oscillatory activity. Here we systematically present evidence in favor of an involvement of entrained neural oscillations in the processing of rhythmic input while critically pointing out which questions still need to be addressed before this evidence could be considered conclusive...

Introduction: Over-distension of urinary bladder in a high spinal cord injury patient is a triggering factor for autonomic dysreflexia. Removing triggering factors is vital to prevent autonomic dysreflexia. Case presentation: A 36-year-old tetraplegic patient, who was managed by intermittent catheterizations performed by caregivers, developed recurrent autonomic dysreflexia during a week due to: 1) carers not performing intermittent catheterizations every night; 2) infrequent catheterizations during the day, leading to distension of urinary bladder...

This article provides a brief historical perspective on the integration of physiology into the concept of the pace of life of birds, evaluates the fit of immune function into this framework, and asks what it will take to fruitfully understand immune functioning of birds in pace of life studies in the future. In the late 1970s, physiology started to seriously enter avian life history ecology, with energy as the main currency of interest, inspired by David Lack's work in the preceding decades emphasizing how food availability explained life history variation...

Industrial methanol production involves a multi component feed containing methanol, water and trace levels of ethanol being refined to produce AA grade methanol at high product recovery. Due to practical constraints, the bottoms discharge of the column is primarily water with only trace of methanol impurities. As a result of these constraints, ethanol, which is a non-key middle boiling component gets "trapped" near the side draw of the column forming an ethanol bulge, which in turn results in non-linear, inverse, time and state varying behaviour of the side draw ethanol composition...

BACKGROUND: Depression is the largest contributor to disease burden globally. The evidence favouring physical activity as a treatment for mild-to-moderate depression is extensive and relatively uncontested. It is unclear, however, how to increase an uptake of physical activity amongst individuals experiencing mild-to-moderate depression. This leaves professionals with no guidance on how to help people experiencing mild-to-moderate depression to take up physical activity. The purpose of this study was to scope the evidence on interventions to increase the uptake of physical activity amongst individuals experiencing mild-to-moderate depression, and to develop a model of the mechanisms by which they are hypothesised to work...

In sports motion analysis, observation is a prerequisite for understanding the quality of motions. This paper introduces a novel approach to detect and segment sports motions using a wearable sensor for supporting systematic observation. The main goal is, for convenient analysis, to automatically provide motion data, which are temporally classified according to the phase definition. For explicit segmentation, a motion model is defined as a sequence of sub-motions with boundary states. A sequence classifier based on deep neural networks is designed to detect sports motions from continuous sensor inputs...

Nowadays, Physical Web together with the increase in the use of mobile devices, Global Positioning System (GPS), and Social Networking Sites (SNS) have caused users to share enriched information on the Web such as their tourist experiences. Therefore, an area that has been significantly improved by using the contextual information provided by these technologies is tourism. In this way, the main goals of this work are to propose and develop an algorithm focused on the recommendation of Smart Point of Interaction (Smart POI) for a specific user according to his/her preferences and the Smart POIs' context...

Objectives: Sickle cell disease (SCD) predominately affects Black Americans. This is the first study of its kind to describe the racial bias experiences of youth with SCD and their reactions to these experiences. Methods: Participants were 20 youth with SCD (ages 13-21 years) who were asked to describe any racial bias events they experienced, as recorded on the Perception of Racism in Children and Youth measure (PRaCY). Interviews were recorded, transcribed, and analyzed by two independent raters using a conventional content analysis approach...

Amyloid-β (Aβ) protein aggregates through a complex pathway to progress from monomers to soluble oligomers and ultimately insoluble fibrils. Due to the dynamic nature of aggregation, it has proven exceedingly difficult to determine the precise interactions that lead to the formation of transient oligomers. Here, a statistical thermodynamic model has been developed to elucidate these interactions. Aβ1-42 was simulated using fully-atomistic replica exchange molecular dynamics. We use an ensemble of approximately 5×105 configurations taken from simulation as input in a self-consistent field theory that explicitly accounts for the size, shape and charge distribution of both the amino acids comprising Aβ and all molecular species present in solution...

BACKGROUND: In the last decade, the number of patients continuously deeply sedated until death increased up to fourfold. The reasons for this increase remain unclear. OBJECTIVE: To identify socio-demographic and clinical characteristics of sedated patients, and concurrent possibly life-shortening medical end-of-life decisions. DESIGN: Cross-sectional death certificate study in German-speaking Switzerland in 2001 and 2013. PARTICIPANTS: Non-sudden and expected deaths (2001: N = 2281, 2013: N = 2256) based on a random sample of death certificates and followed by an anonymous survey on end-of-life practices among attending physicians...

Background: Evaluation of community and public engagement in research is important to deepen understanding of how engagement works and to enhance its effectiveness. Theories of change have been recommended for evaluating community engagement, for their ability to make explicit intended outcomes and understandings of how engagement activities contribute to these outcomes. However, there are few documented examples of using theories of change for evaluation of engagement. This article reports experience of using theories of change to develop a framework for evaluating community engagement in research at a clinical research organisation in Malawi...

Several studies have identified blood transcriptomic signatures that can distinguish active from latent Tuberculosis (TB). The purpose of this study was to assess how well these existing gene profiles classify TB disease in a South Indian population. RNA sequencing was performed on whole blood PAXgene samples collected from 28 TB patients and 16 latently TB infected (LTBI) subjects enrolled as part of an ongoing household contact study. Differential gene expression and clustering analyses were performed and compared with explicit predictive testing of TB and LTBI individuals based on established gene signatures...

Animal abuse adversely affects animal health and welfare and has been associated with interpersonal violence in studies of individuals. However, if that association also depends on sociocultural contexts and can be detected on a geographic scale, a wider source of data can be used to identify risk areas to support the surveillance of both types of violence. In this study, we evaluated the association between interpersonal violence notifications, animal abuse notifications and an index of social vulnerability in São Paulo City, on a geographic scale, using Bayesian spatial models...

BACKGROUND: South Sudan has one of the worst health and maternal health situations in the world. Across South Sudan, while maternal health services at the primary care level are not well developed, even where they exist, many women do not use them. Developing location specific understanding of what hinders women from using services is key to developing and implementing locally appropriate public health interventions. METHODS: A qualitative study was conducted to gain insight into what hinders women from using maternal health services...

Existing regulations seek to protect the public from exposure to polychlorinated biphenyls (PCBs) in food, water, and soil. Exposure to PCBs in ambient air has recently been given explicit consideration in the human health risk assessments that form the basis of risk management decisions at contaminated sites. The objective of this paper is to examine how ambient air exposure to PCBs is regulated and monitored at five contaminated sites in the United States. We reviewed online accessible materials (including Environmental Protection Agency-site specific websites, data repositories, and other agency websites)...
