In this study, an innovative adaptive sliding mode fault-tolerant control approach is developed for an over-actuated vertical takeoff and landing (VTOL) fixed-wing unmanned aerial vehicle (UAV) with the capability to suppress overestimation of adaptive parameters. This method is designed to effectively address model uncertainties and actuator faults witho ...

Background: Common consequences of a stroke include impaired motor and cognitive function, with both being linked to increased falls and frailty. Intra-individual variability (IIV) of cognitive performance, which refers to the within-person trial-to-trial variation in reaction time during cognitive tasks, may be a useful predictor for falls in older adult ...

Cost-effectiveness guidelines recommend including productivity losses in economic evaluations conducted from a societal perspective. However, work productivity loss estimates, including absenteeism and presenteeism, are lacking for a general working population. This limits the ability of researchers and decision makers to comprehensively evaluate the incr ...

Decision-making among prey often involves balancing fitness-related activities, such as foraging and mating, with the need to avoid predation. These trade-offs may be influenced by sex, especially among sexually dimorphic species where males and females face different selection pressures. Consistent with the 'Distracted Male Hypothesis', male Trin ...

Socioecological models of health view romantic relationships as micro-social systems in which spouses influence one another's health-related thoughts, feelings, and behaviors. Although prior work suggests spousal interdependence in eating behaviors, the degree of interdependence may vary as a ...

The fabrication of conductive polymer composites (CPCs) using polydimethylsiloxane (PDMS) and poly(3,4-ethylene dioxythiophene): poly(4-styrene-sulfonate) (PEDOT: PSS) as a matrix with multi-walled carbon nanotubes (MWCNTs) and silver nanoparticles (AgNPs) as fillers was investigated to determine their potential for use in applications such as electromagn ...

Characterizing and manipulating cellular behavior requires a mechanistic understanding of the causal interactions between cellular components. We present an approach to detect causal interactions between genes without the need to perturb the physiological state of cells. This approach exploits naturally occurring cell-to-cell variability which is experime ...

Background: Stroke is a leading cause of death and disability, with proprioceptive impairments affecting up to 64% of survivors. These impairments hinder sensorimotor recovery, significantly impacting poststroke quality of life. Proprioception depends on an integrated brain network but remains underexplored due to limitations in clinical assessments, hind ...

In this paper, a new control approach is proposed for the synchronization and stabilization of a class of chaotic systems with unknown dynamics and input nonlinearities. Type-3 fuzzy logic systems (T3-FLSs) are developed to adaptively model the dynamics of both master and slave systems in real time. The input is affected by sector-bounded hysteresis and q ...

The apolipoprotein E4 (APOE4) allele is the strongest genetic risk factor for Alzheimer's disease (AD) and is linked to poorer cerebrovascular health. Cerebrovascular reactivity (CVR), an indicator of vascular reserve, and cerebral pulsatility (CP), a marker of vascular stiffness, are sensitive biomarkers of early vascular dysfunction associated with ...
