Efficiency at maximum power of low dissipation Carnot engines [PDF]

, 2010
We study the efficiency at maximum power, $\eta^*$, of engines performing finite-time Carnot cycles between a hot and a cold reservoir at temperatures $T_h$ and $T_c$, respectively.

Validation of International Classification of Diseases (ICD) code‐based case definitions of immune checkpoint inhibitor associated inflammatory arthritis from administrative health data

Arthritis &Rheumatology, Accepted Article.
Background Immune checkpoint inhibitors (ICIs) for cancer can lead to immune‐related adverse events, including ICI‐associated inflammatory arthritis (ICI‐IA). There are no validated International Classification of Diseases (ICD) code–based case definitions for ICI‐IA.

Cryomagma ascent on Europa [PDF]

, 2019
Europa's surface exhibits morphological features which, associated with a low crater density, might be interpreted to have formed as a result of recent cryovolcanic activity. In particular, the morphology of smooth deposits covering parts of the surface,

Virtual reality‐based reminiscence therapy for older adults to improve psychological well‐being and cognition: A systematic review

Journal of Clinical Nursing, EarlyView.
Abstract Background Virtual reality‐reminiscence therapy (VR‐RT) has increasingly been applied to older adults to improve psychological well‐being and cognition. Objective This review aims to identify (1) the design characteristics of conducting a VR‐RT and (2) the effects of VR‐RT on the user experience, cognitive outcomes and psychological well‐being.

Entropy generation for MHD pulsating stratified liquid flow between two permeable beds

Nonlinear Analysis
In natural systems such as lakes, reservoirs, and the upper ocean layers, temperature-induced stratified fluid flows are frequently observed. Numerous studies have explored key aspects of these flows, including stability, mixing, and thermal transport ...
