Attaining Carnot efficiency with quantum and nanoscale heat engines
npj Quantum Information, 2021 A heat engine operating in the one-shot finite-size regime, where systems composed of a small number of quantum particles interact with hot and cold baths and are restricted to one-shot measurements, delivers fluctuating work.

Dispersion‐Less Dissipative Soliton Fiber Laser
Laser &Photonics Reviews, EarlyView.A dispersion‐less fiber laser architecture generates high‐energy, pedestal‐free picosecond pulses without resorting to conventional pulse stretching. This energy‐managed laser achieves remarkable flexibility in pulse parameters, delivering up to 0.54 μJ$\mathrm{\mu}\mathrm{J}$ pulses with minimal spectral distortion using standard telecom components ...

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 ...

The performance analysis of reversed Carnot cycle and reversed p-V cycle
Scientia Sinica Technologica, 2018 A reversed thermodynamic cycle is a cycle which consumes mechnical work and moves heat energy from a source with lower temperature to a source with higher temperature, and the coefficient of performance (COP) is generally applied to describe its ...
