New ion trap for atomic frequency standard applications [PDF]
A novel linear ion trap that permits storage of a large number of ions with reduced susceptibility to the second-order Doppler effect caused by the radio frequency (RF) confining fields has been designed and built.

Compact Terahertz Dual‐Comb Spectroscopy with All‐Digitally Generated Adaptive Clock
Advanced Physics Research, EarlyView.This work demonstrates a compact terahertz dual‐comb spectrometer using an all‐digital adaptive clock generated on an FPGA. This system achieves high precision across 1.6 THz, resolves over 24 000 comb lines with kHz resolution, and offers enhanced stability and a simplified architecture compared to analog‐based methods.

Rotational Doppler Effect of Vector Beams
PhotonicsThe optical rotational Doppler effect occurs when vortex beams are scattered by rotating objects and demonstrate the Doppler frequency shifts in scattered beams, which are associated with the optical angular momentum of vortex beams and the relative ...

Adipocytes in Aortic Stenosis: Association With Clinical and Morphological Indices
Clinical Anatomy, EarlyView.ABSTRACT Recently, great attention has been given to understanding the new pathogenetic mechanisms underlying aortic stenosis (AS). The study aims to understand the role of mature adipocytes in AS and their association with histologic, clinical, and echocardiographic data, an area previously overlooked in AS research.
