This article presents a high-level overview of the IEEE 802.22 standard for cognitive wireless regional area networks (WRANs) that is under development in 802 LAN/MAN Standards Committee.
Nursing students exhibit a higher incidence of mental disorders. Studies have identified psychological stress contributes to elevated depression symptoms through reappraisal cognitive in nursing students. However, there is little research exploring the knowledge regarding role ruminative thinking mediating associations between and symptoms. Guiding by non-hemostatic model control theory, study aims investigate chained mediation ruminate among undergraduates. A total 1,220 undergraduates were...
One of the key challenges emerging cognitive radio-based IEEE 802.22 wireless regional area networks (WRANs) is to address two apparently conflicting requirements: ensuring QoS satisfaction for WRAN services while providing reliable spectrum sensing guaranteeing licensed user protection. To perform sensing, in basic operation mode on a single frequency band (non-hopping mode), one must allocate quiet times, that is, periodically interrupt data transmission could impair WRAN. This critical...
Abstract Background Mental health problems are critical and common in medical staff working Intensive Care Units (ICU) even at the late stage of COVID-19, particularly for nurses. There is little research to explore inner relationships between syndromes, such as depression burnout. Network analysis (NA) was a novel approach quantified correlations mental variables from perspective mathematics. This study investigate interactions burnout symptoms through NA among ICU Method A cross-sectional...
Objective We evaluated a variety of non-invasive physiological technologies and series test approaches for examination aviator performances under conditions mental workload in order to provide standard real-time psychological pilot fatigue assessments. Methods Twenty-one male aviators were selected simulated flight hypobaric cabin with artificial altitude 2400 meter above sea level. The lasted 1.5 h, was repeated two times an intervening 0.5 h rest period outside the cabin. Subjective...
The purpose of this study is to compare the efficacy mind-body practices (MBPs) and multiple psychological methods, identify optimal method for relieving work-related stress among healthcare workers (HCWs) by network meta-analysis (NMA).
Although avoiding harmful interference to licensed incumbents is the prime concern of system design for emerging IEEE 802.22 standard, another key challenge cognitive radio based systems how dynamically share scarce spectrum among collocated network cells so that performance degradation, due mutual co-channel interference, effectively mitigated. This paper describes a distributed, cooperative, and real-time sharing protocol called On-Demand Spectrum Contention (ODSC) employs interactive MAC...
A prolonged period of vigilance task will lead to decrement and a drop in cognitive efficiency. Although transcranial direct current stimulation (tDCS) can be used improve performance following decrement, the findings this area study are inconsistent. This aims identify neuroelectrophysiological behavioral effects tDCS over left dorsolateral prefrontal cortex (DLPFC) on executive under continuous monotonous condition. We recruited 29 participants who randomly received 30 min active or sham...
The present study explored the neural mechanism underlying effect of moderate and transient hypoxic exposure on mental rotation two-dimensional letters in both normal mirror versions. Event-related potential data behavioral were acquired task discrimination between mirrored versions separately conditions normoxia (simulated sea level) hypoxia 5000 meter altitude). results revealed no significant difference response time error rate. However, obvious differences these two ERP found. First,...
Key points Rapid alterations of gravitational stress during high‐performance aircraft push–pull manoeuvres induce dramatic shifts in volume and pressure within the circulation system, which may result loss consciousness due to rapid significant reduction cerebral perfusion. There are still no specific effective countermeasures so far. We found that lower body negative (LBNP), applied prior −Gz released at subsequent transition +Gz, could effectively counteract haemodynamic induced by a...
Objective. Pilots are commonly exposed to some sources of emotional and cognitive stressors, especially for flight cadets, which have an important influence on safety. The present study aimed the relationship between trait factors, state, mental workload simulated performance (SFP) under acute psychological stress situation. Methods. Fifty-five undergraduates were included in study. Wong Law intelligence scale (WLEIS), state-trait anxiety inventory (STAI), rating questionnaire (SRQ) National...
There is a paucity of research that has explored "False Alarm" mechanisms. In order to remedy this deficiency in knowledge, the present study used event-related potential (ERP) technology reveal mechanisms underlying False Alarm response fear stimuli.This selected snakes as experimental materials and "oddball paradigm" was simulate conditions Alarm. The mechanism revealed by comparing cognitive processing similarities differences between real toy snakes.Event-related findings demonstrated...
Coronavirus disease-2019 (COVID-19) has caused continuous effects on the global public, especially for susceptible and vulnerable populations like pregnant women. COVID-19-related studies publications have shown blowout development, making it challenging to identify development trends hot areas by using traditional review methods such massive data. Aimed perform a bibliometric analysis explore status hotspots of COVID-19 in obstetrics. An online search was conducted Web Science Core...
Frequency Assignment is an important approach to mitigate multi-cell interference in cellular systems. In this paper, we consider frequency hopping as one possible assignment approach. particular focus our attention on cognitive radio systems of the very promising future access technologies, taking IEEE 802.22 example. While optimal for such a system conceptually straightforward well computationally complex, demonstrate that usage distributed methods leads significant loss efficiency....
OBJECTIVES: This study investigated the effectiveness and identified cutoff values of computer-based Farnsworth-Munsell 100-Hue (CFM-100) test for screening color vision deficiencies in pre-employment examination civil aviators China.METHODS: Firstly, subjects were stratified into normal, weakness, blindness with Ishihara pseudoisochromatic plate (IPPT) by two ophthalmologists. Then they randomly completed CFM-100 (FM-100) tests. Total error scores (TES) time taken FM-100 analyzed...
