Noncontact detection of human vital signs based on miniaturized Doppler radar systems (DRSs) can be widely used in healthcare and biomedical applications. Although significant progresses have been achieved, a reliable wireless the presence large-scale random body movements remains technical challenge. In this paper, comprehensive use high-dynamic-range architecture linearized phase demodulation algorithms, we further introduce matched filters to retrieve respiration heartbeat spectra...
To address the thermal-expansion coefficient mismatch between metal vapor chambers and semiconductor materials, multilayer laser processing was employed to fabricate a ceramic-based stepped microgroove wick (SMW) for ceramic chamber. The depth of SMW ranged from 200 500 μm, surface grooves characterized by micro/nano melt. boiling heat transfer performance under atmospheric pressure investigated, revealing maximum critical flux (CHF) increase in 64% compared with smooth plate. enhanced is...
A large-scale, high-gain, high-efficiency, optically transparent grid array antenna operating at millimeter-wave frequencies is proposed in this letter. The employed to mitigate the feeding network loss caused by lossy conductor, which composed of a series rectangular loops directly connected its neighbors rather than through network. adopts dual ports and achieves synthetic gain anti-phase feeding. By loading patches on radiators outer region, radiation impedance characteristics are...
Unbalanced radial force is one of the most urgent issues for internal gear pumps (IGPs) working at high pressures. A numerical model prediction unbalanced essential structural design pumps, facing challenges engagement description, dynamic mesh method, and so on. In this work, a three-dimensional computational fluid dynamics an IGP with pressure was established based on 2.5-dimensional cavitation engagements included. The flow behavior hydraulic high-pressure were studied, experiments pump...
Background Uneven distribution of health resources is higher in Tibet than other regions. The development core professional capability for general practitioners (GPs) the main goal continuing medical education (CME) training programs. Aim This study aimed to explore needs CME GPs and provide advice policy, practice, curriculums. Methods We conducted a cross-sectional online survey among Autonomous Region, China. designed an questionnaire including demographic section, contents, formats about...
In the past years, significant progresses have been achieved in signpost-based indoor navigation and positioning systems. this paper, inspired by recent bionic researches on long-distance animal geomagnetic navigation, we propose an autonomous local system, based artificially established magnetic gradient for in-grid or desktop applications. Without using any magnetic-field strength information, proposed can be accomplished matching a spatial angle included direction of vector field defined...
Chronic insomnia is a common yet often overlooked issue in primary health care. This study investigated the knowledge, attitude, and practices of chronic management among general practitioners (GPs).
