The cost of Energy Storage System (ESS) for frequency regulation is difficult to calculate due to battery’s degradation when an ESS is in grid-connected operation. To solve this problem, the influence mechanism of actual operating conditions on the life degradation of Li-ion battery energy storage is analyzed. A control strategy of Li-ion ESS participating in grid frequency regulation is constr...

CONCLUSIONS A 'Positioner' preventing sleeping on the back can effectively reduce obstructive sleep apnea (OSA), but not always snoring for patients with long-term OSA. By preference, the device should be used for younger snorers without OSA as a training tool to avoid sleeping on the back. Instructions and support by a nurse are necessary for compliance. OBJECTIVES Snoring is a progressive c...

BACKGROUND AND PURPOSE In stroke patients, obstructive sleep apnea (OSA) is associated with poorer functional outcomes than in those without OSA. We hypothesized that treatment of OSA by continuous positive airway pressure (CPAP) in stroke patients would enhance motor, functional, and neurocognitive recovery. METHODS This was a randomized, open label, parallel group trial with blind assessmen...

INTRODUCTION The mortality of Parkinson's disease (PD) and its associated risk factors among clinically definite PD patients in China has been rarely investigated. Our study aimed to identify the mortality rates and predictors of death in PD patients in China. METHODS 157 consecutive, clinically definite PD patients from the urban area of Shanghai were recruited from a central hospital based ...

Background Three hours per week of vigorous physical activity is found to be associated with reduced odds of sleep-disordered breathing. Aim To investigate whether 12 weeks of high-intensity interval training (HIIT) reduced the apnoea-hypopnea index (AHI) in obese subjects with moderate-to-severe obstructive sleep apnoea. Methods In a prospective randomised controlled exercise study, 30 (bo...

OBJECTIVE Studies related to sleep disorders and polysomnography (PSG) among chronic daily headache patients are rare. We studied this and compared chronic migraine (CM) with chronic tension-type headache. METHODS Eighty-three patients were recruited. They were evaluated by semi-structured interview, headache, and sleep diaries along with Epworth Sleepiness Scale score and insomnia symptom sc...
