The objective of the present paper is to study 4-dimensional weakly Ricci symmetric spacetimes $(WRS)_4$ with non-zero constant scalar. We prove that such a satisfying $F(R)$-gravity field equations represents perfect fluid vanishing vorticity. Some energy conditions are studied under current setting constrain functional form $F(R)$. examine couple popular toy models in $F(R)$-gravity, $F(R)=e^...

In this paper we characterize weakly Ricci-symmetric spacetimes (WRS)n endowed with the Gray?s Decomposition. We provide, several interesting results of in addition discuss some based on Generalized Robertson Walker (GRW) spacetimes. Moreover, study which satisfy f (R, T)-gravity equation.

Purpose: To calculate the real-ear insertion gain (REIG) according to types of hearing aids, we evaluated preferred REIGs Korean hearing-impaired listeners and psychoacoustic differences between open-canal fitting (OF) closed-canal (CF).Methods: The subjects with sensorineural loss were divided into OF group (4 monaural fittings, 15 binaural fittings 34 ears), CF (8 13 ears). There no statistic...

This paper describes the Distributed Collaboration and Interaction (DCI) environment, which supports interaction among humans and automated software systems. The DCI approach uses intermediate liaison agents associated with each human to provide an interfacing layer between the human and the automation. We have applied a DCI prototype to help human engineers interact with automated control soft...

Abstract Bay–shelf exchange is critical to coastal systems because it promotes self-purification or pollution dilution of the systems. In this study, effects wave–current interactions on bay–shelf are explored in a micromesotidal system—Daya Bay southern China. Waves can enlarge shear-induced seaward transport and reduce residual-current-induced landward transport, which benefits exchange; howe...

This dataset provides a shapefile containing approximately 3500 polygons with the location, extent, size, and year of clearcut harvest events occurring between 1984 and 2015 in forested areas of the northern Colorado, Landsat WRS-2 scene Path 034, Row 032. Harvest events were modeled and mapped using a 32 year time series of Landsat imagery, the LandTrendr algorithm, and ancillary datasets. The...

There is a high prevalence of job burnout in physicians, impacting both the professional and personal levels. This study aimed to investigate whether physicians with show specific pathological traits facets their personalities compared healthy controls, according dimensional personality models ICD-11 DSM-5. The role perceived stress, anxiety, depression were exploratively investigated regarding...

To understand the spatio-temporal changes in water resources carrying capacity (WRCC) of Pearl River Delta (PRD), 19 indicators were selected from three subsystems (water resources, socio-economic, and eco-environment), entropy weight-TOPSIS model was employed to analyze WRCC each cities PRD 2015 2020. As result shows, subsystem (WRS) had largest weight evaluation system, followed by socio-econ...
