Approaching Carnot efficiency at maximum power in linear response regime
, 2019 We construct an example of heat engine whose efficiency at maximum power breaks down the previously derived bounds in the linear response regime. Such example takes a classical harmonic oscillator as the working substance undergoing a finite-time Otto ...

Can tropical cyclones exist near the Equator?
Quarterly Journal of the Royal Meteorological Society, EarlyView.Schematic showing how a developed TC responds to reduced Coriolis parameter (f). Zero‐f lowers inertial stability and increases agradient force, enhancing radial inflow at lower levels. Stronger inflow deepens the inflow layer and promotes convergence, intensifying convection and downdrafts in outer rainbands.

Carnot Model and Theoretical Efficiency of Large-Temperature-Difference of Absorption Cycle
Zhileng xuebao, 2005 The Carnot analysis method was proposed for the simplification of the thermodynamic analysis of the absorption cycle,by the comparison of the absorption cycle and the compression cycle.The system with two evaporators and two absorbers that is suitable ...

Small Structures, EarlyView.To enhance phosphate removal during peritoneal dialysis, a new dialysate formulation with designed surfactant‐coated iron oxide nanoparticles has been shown to be very effective through experiments in laboratory‐scale dialysis setups. Several transport mechanisms, including electrodiffusion and the Gibbs–Donnan effect, have been evidenced, providing ...

Comment on: "Sadi Carnot on Carnot's theorem"
, 2003 Carnot established in 1824 that the efficiency $\eta_{C}$ of reversible engines operating between a hot bath at absolute temperature $T_{hot}$ and a cold bath at temperature $T_{cold}$ is equal to $1-T_{cold}/T_{hot}$.

Efficiency at maximum power: An analytically solvable model for stochastic heat engines
, 2007 We study a class of cyclic Brownian heat engines in the framework of finite-time thermodynamics. For infinitely long cycle times, the engine works at the Carnot efficiency limit producing, however, zero power. For the efficiency at maximum power, we find

Allergy, EarlyView.ABSTRACT Background Allergic rhinitis (AR) impacts quality of life, work and school productivity. Over the last years, an important body of evidence resulting from mHealth data has led to a better understanding of AR. Such advances have motivated an EAACI‐endorsed update of the Allergic Rhinitis and its Impact on Asthma (ARIA) guidelines (ARIA 2024 ...
