A Two‐Stage Questionnaire and Actigraphy Screening for iRBD in a Multicenter Retrospective Cohort

open access: yesAnnals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Objective Isolated rapid‐eye‐movement sleep behavior disorder is a prodromal marker of synucleinopathies. However, most cases remain undiagnosed due to the insufficient predictive value of questionnaires and limited access to confirmatory video‐polysomnography. We assessed a two‐stage screening strategy combining a brief questionnaire on rapid‐

Prevalence of Systemic Lupus Erythematosus in Australia, 2010–2022: A Population‐Based Study Using Linked National Administrative Health Data

open access: yesArthritis Care &Research, EarlyView.
Objective Systemic lupus erythematosus (SLE) is a heterogenous inflammatory condition with widely varying global prevalence estimates. The frequency of SLE in the general population of Australia has been reported to be notably lower than contemporary estimates in countries such as the United States or United Kingdom, at 19 to 39 per 100,000 as opposed ...

Formal and Informal Social Care in People With Rheumatic and Musculoskeletal Diseases: A Cross‐Sectional Multicenter Survey

open access: yesArthritis Care &Research, EarlyView.
Objective Rheumatic and musculoskeletal diseases (RMDs) are leading causes of physical disability, necessitating support with activities of daily living. This study describes social care received by patients with RMDs in two disparate regions of England: Salford (urban) and Norfolk (rural).

Application of antenna selection technology in eight-beam STBC-BF transmit scheme

open access: yesDianxin kexue, 2017
An antenna selection scheme of space-time block coding combined with eight-beamforming (STBC-BF) in massive MIMO system was proposed.Transmit symbols were coded by space-time block coder,then the coded symbols were weighted by antenna array form eight ...

Single-Carrier Space-Time Trellis and Space-Time Block Coding for Dispersive Rayleigh Fading Channels

open access: yes, 2002
In this contribution we propose a novel Space-Time Coding (STC) scheme for transmissions over dispersive Rayleigh fading channels, which invokes a Joint-Detection assisted Minimum Mean Square Error based Decision Feedback Equalizer (JD-MMSE-DFE)for ...

Neighborhood Socioeconomic Status and Short‐Term Functional Outcomes in Systemic Lupus Erythematosus

open access: yesArthritis Care &Research, EarlyView.
Objective Individuals with systemic lupus erythematosus (SLE) can accumulate functional status (FS) impairment. We evaluated the association between neighborhood socioeconomic disadvantage, as measured by the Area Deprivation Index (ADI), and FS in a national SLE sample.

Characterization of Defect Distribution in an Additively Manufactured AlSi10Mg as a Function of Processing Parameters and Correlations with Extreme Value Statistics

open access: yesAdvanced Engineering Materials, EarlyView.
Predicting extreme defects in additive manufacturing remains a key challenge limiting its structural reliability. This study proposes a statistical framework that integrates Extreme Value Theory with advanced process indicators to explore defect–process relationships and improve the estimation of critical defect sizes. The approach provides a basis for

A STBC-BF Transmit Scheme in Massive MIMO System

open access: yesDianxin kexue, 2015
A STBC-BF transmit scheme in massive MIMO system was proposed.Firstly,the signal was space-time block coded,then passed into the eigen-beamformers,respectively.At the receiver,the space-time decoding was performed on two orthogonal beams.The diversity ...

Near-Instantaneously Adaptive Cooperative Schemes based on Space-Time Block Codes and V-BLAST

open access: yes, 2007
In this paper we propose two adaptive schemes for improving the achievable throughput of cooperative diversity aided wireless networks. These schemes are capable of accommodating the channel signal-to-noise ratio (SNR) variation of wireless systems by ...
