The coordination of the various processes involved in language production is a subject of keen debate in writing research. Some authors hold that writing processes can be flexibly coordinated according to task demands, whereas others claim that process coordination is entirely inflexible. For instance, orthographic planning has been shown to ...

Penetration of water molecules into the protein interior under high hydrostatic pressure conditions, leading to protein structural transition, is a well-known phenomenon. The counteracting effect of a naturally occurring osmolyte, trimethylamine-N-oxide (TMAO), against pressure-induced protein denaturation is also well-established. But, what is largely unknown is the mechanism by which TMAO ...

Center of Pressure (CoP) time series exhibit non-stationarity. Most CoP analyses assume a stationary signal, which could lead to measurement inaccuracy. Despite this, few researchers have reported the incidence of CoP non-stationarity or employed procedures to mitigate non-stationarity prior to time-series analysis. Differencing is a pre-processing technique that reduces non-stationarity, ...

Evidence suggests that chlorthalidone has therapeutic advantages over hydrochlorothiazide, perhaps because of a longer antihypertensive effect. Although guidelines such as the Seventh Report of the Joint National Committee on Prevention, Detection, Evaluation, and Treatment of High Blood Pressure treat diuretics as a class, some experts believe chlorthalidone is the diuretic ...
