A mathematical model for entropy generation in a Powell-Eyring nanofluid flow in a porous channel

Heliyon, 2019
The continuous generation of entropy leads to exergy destruction which reduces the performance of a physical system. Hence, entropy minimization becomes necessary.

Leakage Evaluation by Virtual Entropy Generation (VEG) Method

Entropy, 2017
Leakage through microscale or nanoscale cracks is usually hard to observe, difficult to control, and causes significant economic loss. In the present research, the leakage in a pipe was evaluated by the virtual entropy generation (VEG) method. In virtual

Entropy Rates of the Multidimensional Moran Processes and Generalizations

CoRR, 2014
The interrelationships of the fundamental biological processes natural selection, mutation, and stochastic drift are quantified by the entropy rate of Moran processes with mutation, measuring the long-run variation of a Markov process. The entropy rate is shown to behave intuitively with respect to evolutionary parameters such as monotonicity with ...

Entropy Generation during Head-On Interaction of Premixed Flames with Inert Walls within Turbulent Boundary Layers

Entropy, 2022
The statistical behaviours of different entropy generation mechanisms in the head-on interaction of turbulent premixed flames with a chemically inert wall within turbulent boundary layers have been analysed using Direct Numerical Simulation data.

Entropy generation approach for evaluating energy dissipation and temperature rise to predict the fatigue life behaviour in magnesium alloy

Journal of Materials Research and Technology, 2023
The objective of this present study is to use entropy generation to predict the fatigue life behaviour of magnesium alloy. As the energy dissipation rate directly correlates with material degradation and increases in temperature, the entropy generation ...

Long‐Term Outcomes of Patients With Relapsed/Refractory Neuroblastoma Treated on ANBL1221: A Report From the Children's Oncology Group

Pediatric Blood &Cancer, EarlyView.
ABSTRACT Results of COG ANBL1221 changed treatment paradigms for patients with relapsed/refractory neuroblastoma. Chemoimmunotherapy with irinotecan/temozolomide/dinutuximab is now used as both bridge therapy following suboptimal response to induction and as treatment in first relapse.

The Relationship Between Physical Activity and Left Ventricular Remodeling in Childhood Cancer Survivors Treated With Anthracyclines: A Cross‐Sectional Study

Pediatric Blood &Cancer, EarlyView.
ABSTRACT Introduction Anthracycline‐related cardiac remodeling precedes heart failure in childhood cancer survivors. The objectives of this study were to determine the relationships between patient‐specific factors, moderate‐to‐vigorous physical activity (MVPA), and cardiac remodeling.
