Determination of the Critical Stress Associated with Dynamic Phase Transformation in Steels by Means of Free Energy Method

open access: yesMetals, 2018
The double differentiation method overestimates the critical stress associated with the initiation of dynamic transformation (DT) because significant amounts of the dynamic phase must be present in order for its effect on the work hardening rate to be ...

Comparison of a short versus long-course antibiotic therapy for ventilator-associated pneumonia: a systematic review and meta-analysis of randomized controlled trialsResearch in context

open access: yesEClinicalMedicine, 2023
Summary: Background: For ventilator-associated pneumonia (VAP), the safety of short-course versus long-course antibiotic therapy is still debated, especially regarding documented VAP due to non-fermenting Gram-negative bacilli (NF-GNB).

Exploring the relationship between appraisals of stressful encounters and the associated emotions in a work setting [PDF]

open access: yes, 2012
Exploring work stress using a transactional perspective requires researchers to consider not just the role of appraisal of a stressful encounter but also the relationship of this appraisal with emotions.

Seismic attenuation and stress on the San Andreas Fault at Parkfield: are we critical yet?

open access: yesFrontiers in Earth Science
The Parkfield transitional segment of the San Andreas Fault (SAF) is characterized by the production of frequent quasi-periodical M6 events that break the very same asperity.

Critical stress profile for incipient sediment motion on muddy shoals

open access: yesShui kexue jinzhan, 2012
The vertical profile of critical shear stress is determined using both experimental data and in-situ measurements.A tuning fork densimeter is employed to measure the vertical density distributions of mud on the Lianyungang muddy shoals in Jiangsu ...

Comparative Evaluation of Hemodiafiltration, Hemoperfusion, and Standard Hemodialysis on Efficacy, Inflammatory Control, Dialysis Adequacy, and Safety in End‐Stage Renal Disease: A Prospective Observational Study

open access: yesTherapeutic Apheresis and Dialysis, EarlyView.
ABSTRACT Background Chronic micro‐inflammation in patients with end‐stage renal disease (ESRD) is a significant driver of cardiovascular complications and diminished quality of life. While standard hemodialysis (SHD) effectively manages small‐molecule clearance, its ability to remove medium‐to‐large uremic toxins—the primary catalysts of systemic ...

Critical Difference and Biological Variation in Biomarkers of Oxidative Stress and Nutritional Status in Athletes

open access: yes, 2016
The longitudinal monitoring of oxidative stress (OS) in athletes may enable the identification of fatigued states and underperformance. The application of OS biomarker monitoring programs in sport are hindered by reliability and repeatability of in-the ...

Differential recruitment of brain circuits during fear extinction in non-stressed compared to stress resilient animals

open access: yesScientific Reports
Dysfunctional fear responses in post-traumatic stress disorder (PTSD) may be partly explained by an inability to effectively extinguish fear responses elicited by trauma-related cues.

Stress evolution of fault-and-thrust belts in 2D numerical mechanical models

open access: yesFrontiers in Earth Science
We employed numerical models to examine the dynamics of fold-and-thrust belts (FTBs), particularly focusing on the spatial and temporal interplay between stress variations and fault development.
