FEBS Open Bio, EarlyView.Despite frogs avoiding low temperatures, examination of four salamander species revealed that none avoided cold and all possessed cold tolerance. Functional analysis of TRPM8, a cold sensor, showed that all salamander TRPM8s had lost their cold sensitivity.

Annals of Clinical and Translational Neurology, EarlyView.ABSTRACT Background Emerging evidence suggests that low‐frequency neural oscillations are dynamically regulated by consciousness levels, with the recovery of low cortical activity potentially serving as a neurophysiological substrate for conscious emergence. Targeted enhancement of these low‐frequency rhythms in patients with disorders of consciousness

Advanced Engineering Materials, EarlyView.A flexure‐based variable stiffness structure is developed by integrating phase‐change modulation and adhesive interfacial locking of gallium. The design enables a wide stiffness variability, transitioning from soft, flexible behavior to rigid, load‐supporting performance.

Mode locking mechanism in Fourier-domain mode-locked optoelectronic oscillators
Optics ExpressFourier-domain mode-locked (FDML) optoelectronic oscillators (OEOs) are regarded as a promising candidate to generate linearly chirped microwave waveforms (LCMWs) with large time-bandwidth products. Nevertheless, up to date, the mode locking mechanism in FDML-OEOs is still not clear enough.

Noise characteristics of a polarization-duplex dual-comb fiber laser based on a single gain fiber
Results in Optics, 2023 We demonstrate gain-sharing polarization-duplex dual-comb laser. Here, a nonlinear amplifying loop mirror (NALM) with a single gain fiber is used to achieve simultaneous mode-locking for the generation of the two frequency combs with slightly different ...
