We applied three-dimensional X-ray microtomography to image a capillary drainage process (0–1,000 kPa) in cm-scale heterogeneous laminated sandstone containing three distinct regions with different pore sizes study the pressure. used differential imaging distinguish solid, macropore, and five levels of subresolution phases associated each region. The brine saturation distribution was computed b...

Abstract Aiming to investigate the upper critical dimension, d u , of KPZ class, in Saberi A. EPL 103 (2013) 10005, some growth models were numerically analyzed using Cayley trees (CTs) as substrates, a way access their behavior infinite-dimensional limit, and unexpected results reported: logarithmic roughness scaling, differing for EW (indicating that even at nonlinearity...

`gym-saturation` is an OpenAI Gym environment for reinforcement learning (RL) agents capable of proving theorems. Currently, only theorems written in a formal language the Thousands Problems Theorem Provers (TPTP) library clausal normal form (CNF) are supported. implements 'given clause' algorithm (similar to one used Vampire and E Prover). Being Python, was inspired by PyRes. In contrast monol...

a periodic increase in blood pressure (bp) occurs during apneic episodes in patients with obstructive sleep apnea (osa). several factors including hypoxemia and an increase in heart rate (hr) were reported to be responsible for this increased bp. to examine the contribution of these two factors in increasing bp, 35 healthy male subjects (mean age±sd= 23.64±3.80) were studied in three experiment...

Background: Coronavirus disease 2019 (COVID-19) can demonstrate different clinical spectra. Objectives: The current study aimed to analyze the and laboratory risk factors of severe course in patients with COVID-19. Materials Methods: Consecutive a diagnosis COVID-19 pneumonia were included present study. demographic characteristics, comorbid diseases, symptoms, chest computed tomography (CT) fi...

Quantitatively assessing seismic attenuation caused by fluid pressure diffusion (FPD) in partially saturated rocks is challenging because of its sensitivity to the spatial distribution. To address this challenge we performed depressurization experiments induce exsolution carbon dioxide from water a Berea sandstone sample. In first set used medical X-ray computed tomography (CT) characterize At ...

Aim: Computed Tomography (CT) findings, clinical and laboratory data are very important in the diagnosis treatment process of Coronavirus Disease 2019 (COVID-19). In this study, relationship between these findings was investigated. Material method: 93 patients with positive Reverse-Transcriptase Polymerase Chain Reaction (RT-PCR) test for SARS-CoV-2 were included study. CT tests, World Health O...

Abstract In recent years, nuclear magnetic resonance (NMR) logging has become increasingly prevalent in the characterization of rock properties such as porosity, permeability, saturation, and pore size distribution. However, interpreting accurately from NMR data is challenging for some reservoirs. particular, impact salinity, viscosity, saturation on measurements not always clear, which can lea...

nasopharyngeal angiofibroma is a relatively uncommon vascular tumor affecting adolescent males and it characteristically originates in the posterior lateral wall of the nasopharynx. primary extra-nasopharyngeal angiofibroma is very rare. here, i present a case of angiofibroma of the parapharyngeal space in a 53-year-old woman with ct and sonographic findings.
