Clinic (office) blood pressure (BP) measurement has a well-established role in medical practice and is the standard on which most of the literature is based. However, clinic BP has several important limitations, including the potential for inadequate or misleading estimates of a patient’s true BP status and suboptimal prediction of cardiovascular risk. Particularly relevant is the concern that ...

Fatty acid composition of old and new roots was determined for soybeans (Glycine max [L.] Merr. cv Ransom) at root-zone temperatures of 14, 18, and 22 degrees C during a 26-day period. New roots had a greater concentration of polyunsaturated fatty acids than old roots. The ratio of polyunsaturated to saturated fatty acid concentration in new roots exposed to 14 and 18 degrees C peaked at 16 day...

This paper presents a theoretical model which discusses the value of and need for the use of outcome rather than process evaluations of programs for the elderly. The theoretical framework is based on the highly successful philosophical model of statistical quality control used in industry, which assumes the best way to improve quality is to look at the outcomes. Most accreditation associations,...

the goal of this laboratory study is to investigate the effect of pore shapes on seismic wave velocities in carbonate rocks under reservoir conditions. in this research, 41 core plugs of carbonate rocks from oil fields of the southwest of iran were prepared. the compressional and shear wave velocities were measured in both dry and brine saturated samples under several pressures especially reser...

Based on the Tao and Kong (TK) model fractal of soil–water characteristic curve, a simplified relationship between saturated permeability coefficient air-entry value is established in this study: ks = k0ψa−2. It shown that soil determined by its maximum pore size. In order to facilitate mutual prediction saturation value, based data five types UNSODA database, comprehensive proportionality cons...

Geochemical reactions may alter the permeability of leakage pathways in caprocks, which serve a critical role in confining CO2 in geologic carbon sequestration. A caprock specimen from a carbonate formation in the Michigan sedimentary Basin was fractured and studied in a high-pressure core flow experiment. Inflowing brine was saturated with CO2 at 40°C and 10 MPa, resulting in an initial pH of ...

Abstract Transformers have become a standard neural network architecture for many NLP problems, motivating theoretical analysis of their power in terms formal languages. Recent work has shown that transformers with hard attention are quite limited (Hahn, 2020), as they can be simulated by constant-depth AND/OR circuits (Hao et al., 2022). However, is strong assumption, which may complicate the ...

A 2D numerical simulation of the drainage process in a stratified vertical porous channel is performed for different gas flow rates. The porous matrix consists of two cylindrical homogeneous layers of packed sand with different permeability, initially saturated with a wetting phase. The porosity and the permeability of each layer are assumed to be constant. Since the injected gas is provided th...

Gap junctions serve many important roles in various tissues, but their abundance and diversity in neurons is only beginning to be understood. The tracer Neurobiotin has revealed many different networks interconnected by gap junctions in retina. We compared the relative permeabilities of five different retinal gap junctions by measuring their permeabilities to a series of structurally related tr...
