This paper considers the (n,k)-Bernoulli–Laplace urn model in case when there are two urns containing n balls each, with different colors of (red and white). In our setting, total number red white is same. Our focus on large-time behavior corresponding Markov chain tracking a given assuming that selections k at each step obeys α≤k∕n≤β, where α,β constants satisfying 0<α<β<1 2. Under this assumption, cutoff variation distance established window provided. The results solve an open problem...

As more integrated cardiothoracic (CT) surgical residency programs are developed, there is increased interest in factors influencing specialty selection during undergraduate medical education. This study aimed to nationally assess interests and perceptions of CT surgery from students pursuing such interests.

Transcatheter aortic valve replacement (TAVR) has become the dominant form of in United States. During Coronavirus disease 2019 (COVID-19) pandemic, access to elective surgical care was decreased, particularly for TAVR patients. In this study, we examine impact each COVID-19 "wave," on our patient's procedures and their associated outcomes. Methods: After institutional review board approval, conducted a retrospective prospectively maintained database own center's assess time pre-COVID-19...

Abstract Purpose: Publicly available health information is increasingly important for patients and their families. While the average US citizen reads at an 8 th -grade level, electronic educational materials families are often advanced. We assessed quality readability of publicly resources regarding hypoplastic left heart syndrome (HLHS). Methods: queried four search engines “hypoplastic syndrome”, “HLHS”, ventricle”. The top 30 websites from searches on Google, Yahoo!, Bing, Dogpile were...

Probabilistic zero forcing is a graph coloring process in which blue vertices "infect" (color blue) white with probability proportional to the number of neighboring vertices. We introduce reversion probabilistic (RPZF), shares same infection dynamics but also allows for revert being each round. establish tool which, given graph's RPZF Markov transition matrix, calculates that turns all or as well time at this expected occur. For specific families we produce threshold become entirely next...

ABSTRACT Background Evolving trends in organ procurement and technological innovation prompted an investigation into recent trends, indications, outcomes following combined heart–lung transplantation (HLTx). Methods The United Network for Organ Sharing database was queried all adult (≥18 years) HLTx performed between July 1, 2013 June 30, 2023. Patients with previous transplants were excluded. primary endpoint the effect of donor, recipient, characteristics on 1‐ 5‐year survival. Secondary...

Abstract Context Osteopathic medical schools have traditionally placed a heavy emphasis on the field of primary care. While graduating osteopathic students continue to pursue family medicine, internal and pediatrics at higher rates than their allopathic counterparts, it is unknown whether feel that surgical rotations are held similar standards. Objectives The purpose this study was assess student opinions quality clerkships determine if good or poor experiences influenced decision pursuing...

BACKGROUND: Application costs are known for other competitive specialties, but not Integrated Thoracic Surgery Residency (I6).We seek to quantify I6 application costs, assess the value of away rotations and geographic connections, identify characteristics matched applicants. METHODS: We retrospectively reviewed Texas Seeking Transparency in survey-based database applicants (2019-2022).Away rotation analyses excluded 2021 cycle (n=30) due COVID-19 pandemic.RESULTS: Eighty applicant responses...

Placement of foreign bodies within the urethra has intrigued urologists for years. We present case a 30-year-old man who had self-inserted 6 kidney beans into his sexual pleasure. Conservative attempts at removal with bedside interventions were unsuccessful. The patient required operative intervention cystoscopy and urethral body retrieval. No additional trauma was appreciated all extracted. Management patients can be attempted extraction, however proximal or challenging objects may require...

CONTEXT The emergence of COVID-19/SARS-CoV2 (COVID-19) was an outbreak that began in December 2019 and rose to pandemic levels 2020. One the largest problems with COVID-19 is typical delay testing diagnosis can lead additional transmission disease. Under consultation a board-certified radiologist, study team evaluated common radiological findings on computed tomography (CT) compared efficacy chest radiographs (i.e., x-rays) CT diagnosing COVID-19. METHODS In 2020, authors completed...

This paper considers the $(n,k)$-Bernoulli--Laplace model in case when there are two urns, total number of red and white balls is same, selections $k$ at each step on same asymptotic order as $n$ urn. Our main focus large-time behavior corresponding Markov chain tracking a given Under reasonable assumptions ratio $k/n$ $n\rightarrow \infty$, cutoff variation distance established. A window also provided. These results, particular, partially resolve an open problem posed by Eskenazis Nestoridi.

The power domination problem seeks to determine the minimum number of phasor measurement units (PMUs) needed monitor an electric network. We introduce random sensor failure before process occurs and call this fragile process. For a given graph, PMU placement, probability $q$, we study expected observed vertices at termination This value is polynomial in which relate fault-tolerant PMU-defect-robust domination. also that entire graph becomes give results for some families.
