ICON 2019—International Scientific Tendinopathy Symposium Consensus: There are nine core health- related domains for tendinopathy (CORE DOMAINS): Delphi study of healthcare professionals and patients
(2019-11-04)
Background: The absence of any agreed-upon tendon health-related domains hampers advances in clinical tendinopathy research. This void means that researchers report a very wide range of outcome measures in consistently. ...
Hybrid Precoding for Multiuser Millimeter Wave Massive MIMO Systems : A Deep Learning Approach
(2019-11-04)
In multi-user millimeter wave (mmWave) multiple-input-multiple-output (MIMO) systems, hybrid precoding is a crucial task to lower the complexity and cost while achieving a sufficient sum-rate. Previous works on hybrid ...
Cognitive deficits in problematic internet use : meta-analysis of 40 studies
(2019-11-01)
BACKGROUND: Excessive use of the internet is increasingly recognised as a global public health concern. Individual studies have reported cognitive impairment in problematic internet use (PIU), but have suffered from various ...
The clinical challenges of synthetic cathinones
(2019-11-01)
Within the new psychoactive substances (NPS) scenario, several hundreds of different molecules, mostly including synthetic cannabinoids and cathinones, have so far been identified. The aims of the paper were to: (a) identify ...
