STUDY OBJECTIVES Sleep deprivation has a profound effect on cardiovascular regulation through the autonomic nervous system. This study examined the effect of 24-hour total sleep deprivation on muscle sympathetic nerve activity (MSNA), which is a direct measurement of the postganglionic sympathetic efferent innervating the vascular bed in the skeletal muscle and other circulatory structures. D...

Immune system functioning and maintenance entails costs which may limit investment into other processes such as reproduction. Yet, the proximate mechanisms and 'currencies' mediating the costs of immune responses remain elusive. In vertebrates, up-regulation of the innate immune system is associated with rapid phagocytic production of pro-oxidant molecules (so-called 'oxidative burst' responses...

In the process of coal mine production, rock burst accidents near faults occur frequently. order to further reveal induced mechanism fault slip burst, a numerical simulation method for dynamic calculation under influence mining is proposed, and law response characteristics stope are studied. The study shows that with working face getting closer fault, activity number high-energy microseismic ev...

The paper addresses hydrodynamic performance of a slender swimmer furnished with a flexible small-aspect-ratio soft-rayed caudal fin. The recoil of the fin is found by solving the coupled hydro-elastic problem, in which the structure of the fin is modeled by a cantilever of variable cross section and the hydrodynamic forces acting on it are modeled using the elongated body theory. It is shown t...

Paepalantine (9,10-dihydroxy-5,7-dimethoxy-1H-naphto(2,3c)pyran-1-one), a natural isocoumarin isolated from the capitula of Paepalanthus bromelioides (Eriocaulaceae), was assessed for its effect on the respiratory burst (zymosan-stimulated luminol-enhanced chemiluminescence and PMA-stimulated lucigenin-enhanced chemiluminescence) of polymorphonuclear neutrophils in vitro. Special attention was ...

We find that dim gamma-ray bursts (GRBs) are softer than bright GRBs, as indicated on average by data from the Burst and Transient Source Experiment (BATSE) on board the Compton Gamma Ray Observatory. We show that this correlation is statistically significant with respect to variations due to random differences between GRBs. This effect is discernable using a variety of methods and data sets, i...

The authors report on the use of a burst-mode ultrashort pulsed laser source with an emitting wavelength 1030 nm to micro-machining plane areas glass different pulse durations, burst energies, and number sub-pulses per intra-burst rates 65 MHz 2.5 GHz. In investigated parameter range, maximum specific removal are obtained $$11.2\,\upmu \text{m}^{3}/\upmu \text{J}$$ for bursts $$27.0\,\upmu GHz ...
