A study of helicopter stability and control including blade dynamics [PDF]
A linearized model of rotorcraft dynamics has been developed through the use of symbolic automatic equation generating techniques. The dynamic model has been formulated in a unique way such that it can be used to analyze a variety of rotor/body coupling ...

Acoustically swept rotor [PDF]
, 1979 Impulsive noise reduction is provided in a rotor blade by acoustically sweeping the chord line from root to tip so that the acoustic radiation resulting from the summation of potential singularities used to model the flow about the blade tend to cancel ...

Periodontology 2000, EarlyView.Abstract The aim of this comprehensive review was to evaluate comparative studies on horizontal and fixed‐angle centrifugation methods for preparing platelet‐rich fibrin (PRF). Furthermore, additional studies utilizing horizontal PRF (H‐PRF) were systematically investigated.

One day of environment‐induced heat stress causes injury to the murine kidney
Experimental Physiology, EarlyView.Abstract Environment‐induced heat stress (EIHS) results from sustained body temperature elevation owing to prolonged exposure to heat and humidity. We hypothesized that EIHS would cause kidney injury and cellular dysfunction. To test this hypothesis, female C57 mice were exposed to EIHS (n = 14; 37.6°C, 42.0% relative humidity) or thermoneutral (TN ...

Downregulation of microRNA‐494 drives mitochondrial biogenesis and function in trained muscle
Experimental Physiology, EarlyView.Abstract MicroRNAs (miRNAs) are key regulators of cellular processes, including mitochondrial function and energy metabolism. This study explores the regulation of miR‐494 in skeletal muscle and circulation, investigating its response to exercise training and an acute exercise bout, its association with metabolic disorders, and the effects of ...

The Journal of Physiology, EarlyView.Abstract figure legend In silico trials were conducted in 654 virtual patients with atrial fibrillation (AF) to assess the cardioversion efficacy of three pharmacological treatments: single SK and K2P channel block and combined SK+K2P channel inhibition. Left: representative virtual AF patient with the atria inside the torso.

The Journal of Physiology, EarlyView.Abstract figure legend We used an intersectional approach with recombinase‐expressing mice and adeno‐associated virus to map and modulate distinct nociceptive afferents in the vagal ganglia. TRPV1+P2X2+ neurons resided in the nodose ganglion (N), innervated the lungs (many projected into the alveoli) but not the trachea, and projected to the nucleus ...
