Shoaling Internal Solitary Waves and the Formation of Boluses

引用

Open Journal of Fluid Dynamics 2024年第2期14卷 65-82页

作者： Hooman Enayati brian t. Helenbrook Department of Mechanical Engineering Lafayette College Easton PA USA Department of Mechanical & Aerospace Engineering Clarkson University Potsdam NY USA

An internal solitary wave of elevation in a two-layer density stratified system of an incompressible, viscous and homogeneous fluid was studied. the run-up of a wave of elevation encountering different slopes was investigated numerically based on solving the continuity, Navier-Stokes and convective-diffusion equations within the Boussinesq approximation. the commercial software COMSOL Multiphysics was used to conduct the numerical simulations. For gradual shoals, a bolus formed that transported dense fluid up the shoal. the bolus disappeared when it reached its maximum height on the slope due to the draining of the dense fluid. Various shoal angles were simulated to detect the critical angle above which a bolus does not form. An angle of 30 or less resulted in the formation of a bolus. In addition, the simulations demonstrated that the size of the bolus induced by shallower slopes was larger and that the vertical height traveled by the bolus was insensitive to the slope of the shoal.

A comparison of genetic risk score with family history for estimating prostate cancer risk

引用

Asian Journal of Andrology 2016年第4期18卷 515-519页

作者： brian t Helfand Division of Urology NorthShore University HealthSystem University of Chicago Pritzker School of Medicine 2650 Ridge Avenue Evanston IL 60201 USA.

Prostate cancer （PCa） testing is recommended by most authoritative groups for high-risk men including those with a family history of the disease. However, family history information is often limited by patient knowledge and clinician intake, and thus, many men are incorrectly assigned to different risk groups. Alternate methods to assess PCa risk are required. In this review, we discuss how genetic variants, referred to as PCa-risk single-nucleotide polymorphisms, can be used to calculate a genetic risk score （GRS）. GRS assigns a relatively unique value to all men based on the number of PCa-risk SNPs that an individual carries. this GRS value can provide a more precise estimate of a man＇s PCa risk. this is particularly relevant in situations when an individual is unaware of his family history. In addition, GRS has utility and can provide a more precise estimate of risk even among men with a positive family history. It can even distinguish risk among relatives with the same degree of family relationships. taken together, this review serves to provide support for the clinical utility of GRS as an independent test to provide supplemental information to family history. As such, GRS can serve as a platform to help guide-shared decision-making processes regarding the timing and frequency of PCa testing and biopsies.
