Analysis of Influencing Factors of Boundary Layer Transition During Ascent Phase of Hypersonic Vehicle

open access: yes气体物理
The transition of the boundary layer is an important issue that must be considered in the design of hypersonic vehicles. During the ascent phase of the vehicle, both the Mach number and the flight altitude increase simultaneously and affect the location ...

Heterogenous Mental Health Impacts of a Forced Relocation: The Red Zone in Christchurch (New Zealand)

open access: yesHealth Economics, EarlyView.
ABSTRACT People are sometimes forced to move, and it is plausible that such relocation involves significant psychological costs. The challenge in identifying the mental health consequences of moving is that most moves are (at least partly) voluntary so that the sample of movers is self‐selected. We focus on a natural experiment, the government‐mandated

Low Mach number limit of compressible nematic liquid crystal flows with well-prepared initial data in a 3D bounded domain

open access: yesElectronic Journal of Differential Equations, 2019
In this article, we consider the low Mach number limit of the compressible nematic liquid crystal flows in a 3D bounded domain. We establish the uniform estimates with respect to the Mach number for the strong solutions with large initial data in a ...

Global MHD Simulations of Accretion Disks in Cataclysmic Variables (CVs): II The Relative Importance of MRI and Spiral Shocks

open access: yes, 2017
We perform global three-dimensional MHD simulations of unstratified accretion disks in cataclysmic variables (CVs). By including mass inflow via an accretion stream, we are able to evolve the disk to a steady state. We investigate the relative importance

Cost‐effectiveness of a randomized controlled trial comparing low‐dose aspirin to placebo for the prevention of recurrent preterm birth

open access: yesInternational Journal of Gynecology &Obstetrics, Volume 169, Issue 1, Page 399-407, April 2025.
Abstract To assess the cost‐effectiveness of low‐dose aspirin compared to placebo for the prevention of recurrent preterm birth from a healthcare perspective. This was a cost‐effectiveness analysis alongside a multicenter, randomized, double‐blinded, placebo‐controlled trial.

Probing polarization response of monolayer cell cultures with entangled photon pairs

open access: yesJournal of Biophotonics, EarlyView.
Innovative optical detection using polarization and quantum techniques is presented for biological sample analysis. This method utilizes non‐classical light, specifically entangled photon pairs, for enhanced sensitivity in low‐photon‐flux environments.

Comparison of jet Mach number decay data with a correlation and jet spreading contours for a large variety of nozzles [PDF]

open access: yes
Small-scale circular, noncircular, single- and multi-element nozzles with flow areas as large as 122 sq cm were tested with cold airflow at exit Mach numbers from 0.28 to 1.15.

Unstained Blood Smear Analysis: A Review of Rule‐Based, Machine Learning, and Deep Learning Techniques

open access: yesJournal of Biophotonics, EarlyView.
Bright‐field images of unstained smears. (1) Sparse erythrocytes allow straightforward intensity‐ or phase‐based segmentation. (2) Overlapping cells blur boundaries, causing over‐ or under‐segmentation and lowering rule‐based accuracy, thus motivating overlap‐aware algorithms for reliable downstream feature extraction and classification. ABSTRACT Blood
