New design tools for lightweight aerospace structures

open access: yes, 2004
This paper presents two new design tools for lightweight aerospace structures. The first tool is the Tailored Fibre Placement (TFP) design tool TACO. It is used to optimize the fibre orientations of structures made of Carbon Fibre Reinforcement Plastics (

Nondestructive measurements of stoichiometry in undoped semi-insulating gallium arsenide by x-ray bond method

open access: yes, 1996
The influences of microdefects and dislocations on the lattice parameters of undoped semi-insulating GaAs single crystals were analyzed, and a novel nondestructive method for measuring stoichiometry in undoped semi-insulating GaAs was established in this

Effects of IGFBP4 deficiency on human preadipocyte proliferation and differentiation through the IGF1R/AKT pathway

open access: yesFEBS Open Bio, EarlyView.
IGFBP4 knockdown (KD) impairs preadipocyte proliferation and is associated with IGF1R protein downregulation and attenuated AKT phosphorylation. The mechanisms by which IGFBP4 KD influences the IGF1R/AKT signaling pathway involve newly synthesized proteins and lysosomal degradation pathways. Created in BioRender.

Analyze the multi-wire magnetic field of HGMS by semi-analytical method

open access: yesResults in Physics, 2018
In this paper, a semi-analytical method (SAM) to analyze the magnetic field distribution in High-Gradient Magnetic Separation (HGMS) was promoted, constituting a combination of conform mapping (includes Schwarz-Christoffel (S-C) mapping) and finite ...

Visualization of High Frequency Current Distribution By Semi-analytical Method

open access: yes, 2008
To visualize the electromagnetic fields, we have previously proposed a semi-analytical method, which has made it possible to simulate the complex electromagnetic field distributions not obtain by the conventional numerical schemes, such as finite ...

Pathways and pitfalls: a qualitative study of student experiences in biomedical science education

open access: yesFEBS Open Bio, EarlyView.
Biomedical science students from underrepresented backgrounds face barriers including financial strain, disrupted laboratory access and cultural exclusion. Peer networks provide vital support when institutional systems are difficult to navigate. To create inclusive learning environments and achieve academic success, educators should blend active, hands‐

Value of MRI Outcomes for Preventive and Early‐Stage Trials in Spinocerebellar Ataxias 1 and 3

open access: yesAnnals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Objective To examine the value of MRI outcomes as endpoints for preventive and early‐stage trials of two polyglutamine spinocerebellar ataxias (SCAs). Methods A cohort of 100 participants (23 SCA1, 63 SCA3, median Scale for the Assessment and Rating of Ataxia (SARA) score = 5, 42% preataxic, and 14 gene‐negative controls) was scanned at 3T up ...

Study on the Time Domain Semi Analytical Method for Horizontal Vibration of Pile in Saturated Clay

open access: yesApplied Sciences
Under the framework of Biot porous media theory, a fractional order Kelvin model is used to describe the rheological effects of soil skeletons, and a coupled vibration model of saturated clay and a pile foundation is constructed. The Laplace transform is
