Efficacy and safety of low‐dose atorvastatin plus ezetimibe for primary hypercholesterolemia: A randomized, double‐blind, multicenter phase 3 trial

open access: yesLipids, EarlyView.
Low‐dose atorvastatin combined with ezetimibe achieves superior LDL‐C reduction (44.8%) compared with equivalent or higher‐dose statin monotherapy in Korean patients, presenting a more effective and safer therapeutic strategy potentially applicable to broader Asian populations.

Polarization‐Independent Complex Bragg Grating Filters on Silicon Nitride

open access: yesLaser &Photonics Reviews, EarlyView.
This work demonstrates multi‐band polarization‐insensitive optical filters on the 400‐nm thick silicon nitride platform, complying with the LAN‐WDM standard. The filters are based on cladding‐modulated Bragg gratings with judiciously designed grating dimensions.

Flight investigation of XB-70 structural response to oscillatory aerodynamic shaker excitation and correlation with analytical results [PDF]

open access: yes
The low frequency symmetric structural response and damping characteristics of the XB-70 airplane were measured at four flight conditions: heavyweight at a Mach number of 0.87 at an altitude of 7620 meters (25,000 feet); lightweight at a Mach number of 0.

The density variance -- Mach number relation in supersonic, isothermal turbulence

open access: yes, 2010
We examine the relation between the density variance and the mean-square Mach number in supersonic, isothermal turbulence, assumed in several recent analytic models of the star formation process.

Photonic Energy‐Coherence Theorem and Experimental Validations

open access: yesLaser &Photonics Reviews, EarlyView.
A thermodynamic framework for quantum wave‐particle duality is presented, where each behaviors attribute is quantified through the extractable energy of a system. The energy capacity establishes a direct connection to both fringe visibility and path distinguishability. Active control of single‐photon states demonstrates distinct energetic contributions

A MHz−Level Swept Source by Time Stretching the Shot−Noise Limited Supercontinuum Based on a Mode−Locked Laser and the Application in Optical Coherence Tomography

open access: yesLaser &Photonics Reviews, EarlyView.
This work pioneers a 5.7 MHz all−fiber mode−locked laser−based broadband swept−source OCT system, achieving record−breaking performance: 11.4 µm axial resolution and 119 mm detection range. The system demonstrates exceptional coherence and stability, overcoming traditional trade−off between imaging speed and detection range.

Comparison of experimental and theoretical boundary-layer separation for inlets at incidence angle at low-speed conditions [PDF]

open access: yes
Comparisons between experimental and theoretical Mach number distributions and separation locations are presented for the internal surfaces of four different subsonic inlet geometries with exit diameters of 13.97 centimeters.
