Right ventricular (RV) maximal power (PWR(mx)) is dependent on preload. The objective of this study was to test our hypothesis that the PWR(mx) versus end-diastolic volume (EDV) relationship, analogous to the load-independent stroke work (SW) versus EDV relationship (preload-recruitable SW, PRSW), is linear, with the PWR x-axis intercept (V(0PWR)) corresponding to the PRSW intercept (V(0SW)). I...

This study compares the proliferation resistance of DUPIC (Direct Use of Spent PWR Fuel in CANDU) fuel cycle with other fuel cycle cases. The other fuel cycles considered in this study are PWR of once-through mode (PWR-OT), PWR of reprocessing mode (PWR-MOX), in which spent PWR fuel is reprocessed and recovered plutonium is used for making MOX (Mixed Oxide), CANDU with once-through mode (CANDU-...

Cardiac power (PWR) is the continuous product of flow and pressure in the proximal aorta. Our aim was to validate the PWR integral as a marker of left ventricular energy transfer to the aorta, by comparing it to stroke work (SW) under multiple different loading and contractility conditions in subjects without obstructions in the left ventricular outflow tract. Six pigs were under general anesth...

Crash-only component has PWR switch: stop=crash clean shutdown loss of power kernel panic cure transient failure Only one way to go down only one way to come up: start = recover Each component must has a PWR switch uniform behavior Crash-only system = assembly of crash-only components; system PWR switch implemented in terms of components' switches PWR switch is external, does not invoke compone...

Background: Studies have established placental weight ratio (PWR) as a relevant marker of fetal uteroplacental function which reflects whether the fetal and placental growth is proportionate. It decreases across gestation as the placental growth slows and fetal growth accelerates. Preeclampsia and preterm birth are both risk factors of small for gestational age (SGA) off springs with the smalle...

Ramanujacharyulu’s (1964) Power-Weakness Ratio (PWR) measures impact by recursively multiplying the citation matrix by itself until convergence is reached in both the cited and citing dimensions; the quotient of these values is defined as PWR, whereby “cited” is considered as power and “citing” as weakness. Analytically, PWR is an attractive candidate for measuring journal impact because of its...

The placental weight ratio (PWR) is a health indicator that reflects the balance between fetal and placental growth. The PWR is defined as the placental weight divided by the birth weight, and it changes across gestation. Its ranges are not well established. We aimed to establish PWR distributions by gestational age and to investigate whether the PWR distributions vary by fetal growth adequacy,...

Ambient temperature affects plant growth and even minor changes can substantially impact crop yields. The underlying mechanisms of temperature perception and response are just beginning to emerge. Chromatin remodeling, via the eviction of the histone variant H2A.Z containing nucleosomes, is a critical component of thermal response in plants. However, the role of histone modifications remains un...

Histone acetylation is a major epigenetic control mechanism that is tightly linked to the promotion of gene expression. Histone acetylation levels are balanced through the opposing activities of histone acetyltransferases (HATs) and histone deacetylases (HDACs). Arabidopsis HDAC genes (AtHDACs) compose a large gene family, and distinct phenotypes among AtHDAC mutants reflect the functional spec...

A plasmon waveguide resonance (PWR) sensor is designed, fabricated, and tested for self-referenced biosensing. The PWR sensor is able to support two different polarizations, TM and TE. The TM polarization has a large sensitivity to variations in the background refractive index while the TE polarization is more sensitive to the surface properties. The ability of the PWR sensor to simultaneously ...
