Effect of Pre-tensioning Force on Behavior of Buckling Restrained Brace (BRB) Supported by Double Pre-tensioning System [PDF]

, 2023
The study explores the feasibility of a new all-steel buckling restrained brace (BRB) with the double pre-tensioning system as an alternative to conventional concentrically braced frames by using finite element method (ABAQUS program), And to verify ...

Modeling the operational state of suspended roofs with large spans and unique load-bearing elements [PDF]

E3S Web of Conferences
The stress-strain state of hanging systems and support contours in the stages of pre-tensioning of cables, as well as in the processes of construction and operation of unique structures, has been studied.

Adenosine triphosphate as a modulator of protein interactions and stability

FEBS Open Bio, EarlyView.
ATP is best known as the cell's energy currency, but it also shapes how proteins fold, interact, aggregate and form biomolecular condensates. This review explains the emerging physical principles behind these effects, including weak binding to charged protein regions, magnesium‐dependent behaviour and concentration‐dependent control of protein ...

GelMA‐based 3D spheroids recapitulate transcriptomic and functional hallmarks of myeloid sarcoma

FEBS Open Bio, EarlyView.
GelMA 5% hydrogels support the formation of myeloid leukemia spheroids that recapitulate MS‐specific features, including G1 arrest, apoptosis, and ECM‐driven transcriptomic reprogramming. The 3D model mimicked soft‐tissue‐like stiffness and oxygen conditions, and transcriptomic convergence with primary MS samples confirmed its utility as a preclinical ...

Experimental study on internal monitoring structure of a new prestressed anchor cable

Yantu gongcheng xuebao, 2020
On account of their difficult internal stress monitoring, a new type of internal stress monitoring structure for pre-stressed anchor cables is developed and then tested by the destructive tension tests and the repeated tension tests under multi-levelload.

On-Site Manufacturing Method for Pre-Tension U-Type Pre-Stressed Concrete Girders and Analytical Performance Verification of Anchoring Blocks Used for Applying Tension Force

Applied Sciences, 2022
Development of U-type pre-stressed girders has been attempted to increase the length of I-type girders in South Korea. However, a length of 30 m or less is common because the self-weight, according to the post-tension method, is large. In this study, the

Natural Frequencies of Levodopa‐Induced Dyskinesia in Parkinson's Disease

Annals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Objectives Abnormal involuntary movements, known as dyskinesias, are common complications of levodopa treatment in patients with Parkinson's disease and can significantly impair quality of life. The underlying pathophysiology remains unclear, and current therapeutic options are limited.

Architecture‐Driven Sensor Stability in Weft‐Knitted Engineering Textiles

Advanced Engineering Materials, EarlyView.
Textile‐integrated sensor architectures are systematically compared to evaluate their electromechanical behavior under combined mechanical and environmental loading. Pocket‐based integration exhibits stable and reproducible signals, whereas tunnel‐based routing shows higher sensitivity accompanied by increased variability.
