High Bandwidth GaN-Based Micro-LEDs for Multi-Gb/s Visible Light Communications

Abstract: Gallium-nitride (GaN)-based light-emitting diodes (LEDs) are highly efficient sources for general purpose illumination. Visible light communications (VLC) uses these sources to supplement existing wireless communications by offering a large, licence-free region of optical spectrum. Here, we report on progress in the development of micro-scale GaN LEDs (micro-LEDs), optimized for VLC. These blue-emitting micro-LEDs are shown to have very high electrical-to-optical modulation bandwidths, exceeding 800 MHz. The data transmission capabilities of the micro-LEDs are illustrated by demonstrations using ON–OFF-keying, pulse-amplitude modulation, and orthogonal frequency division multiplexing modulation schemes to transmit data over free space at the rates of 1.7, 3.4, and 5 Gb/s, respectively.

Impact of Dietary Fiber Consumption on Insulin Resistance and the Prevention of Type 2 Diabetes.

Abstract: Large prospective cohort studies consistently show associations of a high dietary fiber intake (>25 g/d in women and >38 g/d in men) with a 20-30% reduced risk of developing type 2 diabetes (T2D), after correction for confounders. It is less well recognized that these effects appear to be mainly driven by high intakes of whole grains and insoluble cereal fibers, which typically are nonviscous and do not relevantly influence postprandial glucose responses [i.e., glycemic index (GI)] or are strongly fermented by the gut microbiota in the colon. In contrast, a dietary focus on soluble, viscous, gel-forming, more readily fermentable fiber intakes derived from fruit and certain vegetables yields mixed results and generally does not appear to reduce T2D risk. Although disentangling types of fiber-rich foods and separating these from possible effects related to the GI is an obvious challenge, the common conclusion that key metabolic effects of high-fiber intake are explained by mechanisms that should mainly apply to the soluble, viscous type can be challenged. More recently, studies in humans and animal models focused on gaining mechanistic insights into why especially high-cereal-fiber (HCF) diets appear to improve insulin resistance (IR) and diabetes risk. Although effects of HCF diets on weight loss are only moderate and comparable to other types of dietary fibers, possible novel mechanisms have emerged, which include the prevention of the absorption of dietary protein and modulation of the amino acid metabolic signature. Here we provide an update of our previous review from 2008, with a focus on mechanistic insights of how HCF diets may improve IR and the risk of developing T2D.

An exploration of the psychological factors affecting remote e‐worker's job effectiveness, well‐being and work‐life balance

Abstract: Purpose: The purpose of this paper is to explore the impact of remote e-working on the key research areas of work-life balance, job effectiveness and well-being. The study provides a set of generalisable themes drawn from the key research areas, including building trust, management style and the quality of work and non-working life. Design/methodology/approach: The paper is an exploratory study into the psychological factors affecting remote e-workers using qualitative thematic analysis of eleven in-depth interviews with e-workers, across five organisations and three sectors. All participants worked remotely using technology independent of time and location for several years and considered themselves to be experts. Findings: The paper provides insights into the diverse factors affecting remote e-workers and produces ten emerging themes. Differentiating factors between e-workers included access to technology, ability to work flexibly and individual competencies. Adverse impacts were found on well-being, due to over-working and a lack of time for recuperation. Trust and management style were found to be key influences on e-worker effectiveness. Research limitations/implications: Because of the exploratory nature of the research and approach the research requires further testing for generalisability. The emerging themes could be used to develop a wide-scale survey of e-workers, whereby the themes would be further validated. Practical implications: Practical working examples are provided by the e-workers and those who also manage e-workers based on the ten emerging themes. Originality/value: This paper identifies a number of generalisable themes that can be used to inform the psychological factors affecting remote e-worker effectiveness.
