Effects of asymmetry on the dynamic stability of aircraft [PDF]

open access: yes
The oblique wing concept for transonic aircraft was proposed to reduce drag. The dynamic stability of the aircraft was investigated by analytically determining the stability derivatives at angles of skew ranging from 0 and 45 deg and using these ...

Feasibility and Safety of the ETcath200 Robotic PCI System for Complex Coronary Lesions: A Prospective Single‐Center Study

open access: yesCatheterization and Cardiovascular Interventions, EarlyView.
ABSTRACT Background International robotic‐assisted PCI platforms such as CorPath 200 and CorPath GRX have demonstrated procedural safety and efficacy but are limited by the absence of real‐time tactile feedback and cumbersome device exchange. The ETcath200, the first domestically developed robotic PCI system in China, introduces guidewire force‐sensing

Rolling Factors Deformations and Extensions of Canonical Curves

open access: yes, 2000
A tetragonal canonical curve is the complete intersection of two divisors on a scroll. The equations can be written in `rolling factors' format. For such homogeneous ideals we give methods to compute infinitesimal deformations.

Asynchronous LGBTQ+ Affirming Counseling Training With Early Career Counselors: A Mixed Methods Program Evaluation

open access: yesCounselor Education and Supervision, EarlyView.
ABSTRACT A growing body of research shows that training in LGBTQ+ affirming counseling (LGBTQ+ AC) positively impacts counselors’ perceived knowledge and skills in providing mental health services to LGBTQ+ communities. Existing program evaluations of LGBTQ+ AC, however, have primarily used synchronous delivery formats and cultural competency models ...

Roller bearing geometry design [PDF]

open access: yes
A theory of kinematic stabilization of rolling cylinders is extended and applied to the design of cylindrical roller bearings. The kinematic stabilization mechanism puts a reverse skew into the rolling elements by changing the roller taper.

In Vivo Cytoskeletal AMPA Receptor Transport Imaging in C. elegans

open access: yesCytoskeleton, EarlyView.
ABSTRACT Long‐distance intracellular transport of ionotropic glutamate receptors (iGluRs) is essential for proper excitatory synaptic function underlying learning and memory. Many neuropsychiatric and neurodegenerative conditions have abnormal iGluR transport and trafficking, leading to an intense interest in the mechanisms and factors regulating these

Nonlinear robust controller design for multi-robot systems with unknown payloads [PDF]

open access: yes
This work is concerned with the control problem of a multi-robot system handling a payload with unknown mass properties. Force constraints at the grasp points are considered.

Empowering teachers and fostering pupil climate action in Welsh primary schools

open access: yesThe Curriculum Journal, EarlyView.
Abstract The Curriculum for Wales intends to help students understand and address climate change, but relies on teachers' knowledge and implementation thereof. This article focuses on “The Lifecycle of My Clothes”, a unit of work (UoW) developed by academics and practitioners. The UoW aimed to increase students' awareness of the environmental impact of

Kinematic stability of roller pairs in free rolling contact [PDF]

open access: yes
A set of generalized stability equations was developed for roller pairs in free rolling contact. A symmetric, dual contact model was used. Four possible external contact profiles that possess continuous contacting surfaces were studied. It was found that

Dynamics of bubble absorption over porous membranes in an immersed medium

open access: yesDroplet, EarlyView.
The dynamics of a bubble interacting with a flat, porous superhydrophobic membrane underwater has been illustrated. Abstract Porous superhydrophobic (SHP) membranes are gaining considerable attention due to their excellent underwater absorption and drag reduction properties. They exploit the Cassie‒Baxter state of wetting to remove the bubble in a fast
