Study on stress relaxation characteristics of FGH95 powder superalloy treated by laser shock peening

Materials Research Express, 2022
Aiming at the phenomenon that the residual stress induced by Laser Shock Peening (LSP) will relax and redistribute under various loads, temperature, cyclic load, and the dual treatment of temperature and cyclic load on the residual stress relaxation of ...

Stress relaxation in diblock copolymers [PDF]

, 2008
We study stress relaxation in a strongly segregated lamellar mesophase of diblock copolymers. We consider the extreme limit in which chains are highly stretched and with their junction points confined to narrow interfaces. A lamella can be divided into "stress blobs" at some distance $z$ from the interface, with well defined local modulus $G(z,ω)$ at ...

Physiological effects of heart rate variability biofeedback during laboratory induced congnitive stress [PDF]

, 2012
Includes bibliographical references.Heart rate variability (HRV) biofeedback is effective in reducing stress as well as managing chronic disease. It facilitates easy manipulation of HRV, and, therefore, potentially provides a valuable intervention for ...

Mutant p53R273H disrupts PDPK1 homodimerization and contributes to PDPK1 activation

Molecular Oncology, EarlyView.
How mutant p53R273H drives AKT signaling is unclear. We show that p53R273H, but not wild‐type, directly binds PDPK1 via a mutation‐dependent conformational change. This interaction disrupts inhibitory PDPK1 homodimerization and enhances AKT phosphorylation.

The impact of leukocyte‐associated RNA retention on platelet RNA‐based cancer detection

Molecular Oncology, EarlyView.
Platelets carry RNA signals that may help detect cancer, but platelet samples can also retain RNA from white blood cells. We found that this retained white blood cell signal did not significantly affect machine learning cancer classification, suggesting that the cancer‐related RNA signal in platelets is largely independent of leukocyte‐associated RNA ...

Observations of stress relaxation before earthquakes [PDF]

, 2004
Theory and observations suggest that seismic shear wave splitting, caused by fluid-saturated stress-aligned microcracks, directly monitors low-level deformation before fracturing, faulting and earthquakes occur.

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 ...

Study on stress relaxation and acoustic emission of fractured rocks with different fissure inclinations

Case Studies in Construction Materials
In deep underground engineering, the rheological properties of fractured rock are prominent. This paper investigates the stress relaxation characteristics and damage development in rocks with different fracture inclinations. Uniaxial step-by-step loading

Beta1 subunits enable fentanyl‐induced BK channel activation and opioid regulation of cerebral artery diameter

FEBS Open Bio, EarlyView.
During the current opioid crisis, the majority of overdose deaths are attributed to ultra‐potent synthetic opioids, such as fentanyl. While fentanyl exerts its action via opioid receptors, we propose that potassium channels in the brain blood vessels may also sense fentanyl.
