Results about Proximal and Semi-proximal Spaces
Proximal spaces were defined by J. Bell as those topological spaces $X$ with a compatible uniformity ${\mathfrak U}$ on which Player I has a winning strategy in the so-called proximal on $(X,{\mathfrak U})$. Nyikos defined the class of semi-proximal spaces where Player II has no winning strategy on …

Association of Proximal Femoral Geometry with Osteoporotic Proximal Femur Fracture in Elderly Koreans
… studies demonstrated a relationship between proximal femoral geometry and the risk of hip fracture, but there is relatively little information about the association of these measurements with hip fracture in Korean. Our study assessed the relationship between femur geometry and hip fracture …

Pyrocarbon proximal interphalangeal joint arthroplasty
Arthritis of the proximal interphalangeal joint of the hand can be debilitating disease resulting in pain and stiffness. Treatment is initially conservative but with diseasse progression surgical treatment often becomes necessary. Arthroplasty is one of the surgical options available.

Acidification in the Rat Proximal Jejunum
Acidification of solutions by rat proximal jejunum was investigated in everted sacs, segments and in perfused in vivo loops. Acidification which declines down the jejunum, increased with increasing mucosal glucose concentration, reaching a maximal value. Derived Michaelis-Menten data gave an …

Preferential proximal policy optimization in reinforcement learning
The Proximal Policy Optimization (PPO), a policy gradient method, excels in reinforcement learning with its ”surrogate” objective function and stochastic gradient ascent. However, PPO does not fully consider the significance of frequently encountered states in policy/value updates. To address this, …

Equine proximal phalanx bone properties during growth
… models were constructed of the left forelimb proximal phalanx (P1) bone and used to simulate the loading during quiet standing. Changes in mineral density and bone area fraction in the distal, diaphysis, and proximal regions were evaluated. The diaphysis of the P1 maintained constant strain …

Opportunistic, collaborative and synchronized, proximal device ecology
… an on-device software framework for coordinating proximal consumer electronic devices in order to create a synchronized, opportunistic and collaborative device ecology. The CoSync device ecology combines multiple stand-alone devices and controls them opportunistically as if they were one …

Stress response genes in the human proximal tubules
… was to determine if the immortalized HK-2 human proximal tubule cell line could provide a model system to study the stress response of the proximal tubule cell. Heat stress, elevated temperature at 42.5°C for 1 hr, caused a marked increase only in hsp 70 mRNA and protein, but not that of hsp …

Proximal Causes of Dispersal in Yellow-Bellied Marmots.
The relative importance of adult-yearling interaction, and individual behavioral phenotypes, on dispersal of yearling yellow-bellied marmots was investigated. Two marmot colonies near Gothic, Colorado were studied; one was treated as an experimental colony from which all adults were removed, the …

Ογκολογικές προθέσεις εγγύς μηριαίου - Proximal femur tumor prosthesis
Οι κακοήθεις νεοπλασίες αποτελούν τη δεύτερη κυριότερη αιτία θνησιμότητας παγκοσμίως, με προβλεπόμενη αύξηση της θνησιμότητας τα επόμενα έτη. Το εγγύς τμήμα του μηριαίου οστού αποτελεί συχνή περιοχή ανάπτυξης πρωτοπαθών οστικών σαρκωμάτων, όπου τα σαρκώματα Ewing, τα χονδροσαρκώματα και τα …

RGB and NIR Image Registration for Proximal Multiband Imaging
… are especially pronounced in close-to-ground proximal sensing platforms where the RGB and NIR sensors are separated by a baseline distance. This thesis addresses these challenges by first identifying a set of similarity metrics capable of quantifying spatial misalignment in RGB/NIR image …

Studies of immunoglobulin receptors and human proximal tubular cells
… the glomerulus, may act on Ig receptors in human proximal tubular epithelial cells (PTEC) and may play a direct pathophysiological role in the development of interstitial fibrosis. Specifically, that filtered IgA may bind to the Fcα/μR in IgAN. The activation of Ig receptors may stimulate tubular …

Physical and genetic mapping on mouse proximal chromosome 18
… has been constructed spanning 9 cM on mouse proximal chromosome 18. The contig consists of 49 YAC clones that cover roughly 15% of the chromosome. The map was assembled based on the presence or absence of 38 DNA microsatellites, from proximal DI8Mit109 through distal D18Mit68. The physical …

Characterization of Apoptotic Cells in Equine Proximal Suspensory Desmitis
… in various disciplines. For this study, the proximal portion of the suspensory ligament was collected from 6 horses without suspensory ligament injury (16 ligaments) and 4 horses with degeneration of the suspensory ligament (11 ligaments). Specimens were collected immediately after euthanasia …

Estudio del pliegue ungueal proximal mediante capilaroscopía en individuos prediabéticos
… caso, el lugra preferido es el pliegue ungueal proximal donde se aprecia gran parte del recorrido capilar cutáneo en forma de asa u horquilla. Basándose en los resultados obtenidos mediante la misma técnica en pacientes con enfermedad diabética ya establecida, en el presente trabajo se intenta …

Exclusion from gender counter-stereotypic activities: Proximal and distal effects
<p>The current work explored whether an incidence of exclusion is experienced differently depending on the activity from which one is excluded. Specifically, we investigated whether exclusion from gender stereotypic vs. counter-stereotypic activities affects both how threatening the experience is …

Cyclically-Forced Hyperpycnites of the Ancient Colorado River Proximal Prodelta
… River flow and formation of a fluvial-dominated proximal prodelta. This study contributes to the recently established record of fine-grained hyperpycnites in the ancient rock record and to previous work substantiating the theory that ancient prodeltaic mudrocks may have been primarily deposited …
