Numerical and Experimental Study of Mixing Characteristics in a Spiral Micromixer

open access: yesAsia-Pacific Journal of Chemical Engineering, EarlyView.
ABSTRACT Significant enhancement of mixing performance can be achieved by Dean vortices in spiral channels. In order to deeply explore the mixing mechanisms and variation laws in spiral micromixers, this work designed a spiral micromixer and adopted a combined method of experiments and numerical simulations to analyze the mixing performance and ...

Signature of Einstein-Cartan theory

open access: yesPhysics Letters B
We study the effects of torsion as predicted by the Einstein-Cartan theory in the test-particle non-relativist approximation. We derive the corresponding 2-spinor Hamiltonian.

On the robustness of least-squares Monte Carlo (LSM) for pricing American derivatives [PDF]

open access: yes
This paper analyses the robustness of Least-Squares Monte Carlo, a technique recently proposed by Longstaff and Schwartz (2001) for pricing American options. This method is based on least-squares regressions in which the explanatory variables are certain

An ontological morphological phylogenetic framework for living and extinct ray‐finned fishes (Actinopterygii)

open access: yesThe Anatomical Record, EarlyView.
Abstract The ray‐finned fishes include one out of every two species of living vertebrates on Earth and have an abundant fossil record stretching 380 million years into the past. The division of systematic knowledge of ray‐finned fishes between paleontologists working on extinct animals and neontologists studying extant species has obscured the ...

The persistence of chronic opioid use in patients with inflammatory bowel disease—A nationwide cohort study

open access: yesBritish Journal of Clinical Pharmacology, EarlyView.
Aims Pain is common in patients with Crohn's disease (CD) and ulcerative colitis (UC), and a substantial proportion develop chronic opioid use (COU). We examined the persistence of COU over time and identified factors predicting persistent use. Methods This nationwide Danish cohort study included patients with an initial period of COU (definition: ≥3 ...

Trust first, concerns second: An international vignette study of older adults' preferences towards deprescribing statins

open access: yesBritish Journal of Clinical Pharmacology, EarlyView.
Abstract This study investigated the attitudes and beliefs of older adults towards deprescribing statins in Australia, the United Kingdom and the United States, using an online, vignette‐based study. Presented with a hypothetical scenario in which a general practitioner advised stopping simvastatin, participants rated their level of agreement and ...

A Meta‐Analysis and Simplified Nomenclature for Diagonal Coronary Artery and Ramus Intermedius Across Adult and Pediatric Hearts

open access: yesClinical Anatomy, EarlyView.
ABSTRACT Anatomical descriptions of left‐sided oblique coronary branches remain inconsistent, hindering imaging interpretation and surgical planning. To quantify the prevalence, branching patterns and morphometry of the ramus intermedius (RI) and diagonal branches, and propose a unified nomenclature.
