A new smooth failure criterion for concrete inspired by Lubliner's condition

open access: yesStructural Concrete, EarlyView.
Abstract A new failure criterion with 10 parameters is proposed, based on Lubliner's idea of joining two Drucker–Prager cones. The novelty lies in the way of introducing deviatoric shape variation: through two Podgórski's functions. This feature allows for improving plane stress cross‐section's compatibility with experimental data.

Incremental upper bound modeling of concrete failures in timber‐concrete notched connections

open access: yesStructural Concrete, EarlyView.
Abstract This paper introduces a novel theoretical framework for developing incremental upper bound solutions, which is applied to predict the response of two local concrete failures in timber‐concrete composite (TCC) decks with notched connections. The new approach enables a prediction of the capacity at the onset of failure as well as the entire post‐

Innovative development and structural behavior of hollow columns using inflatable molds

open access: yesStructural Concrete, EarlyView.
Abstract This study introduces a novel approach for constructing hollow columns using precast (PC) methods enhanced by inflatable air tubes as internal molds. The proposed method addresses practical challenges in conventional hollow column construction, such as limited constructability, high production cost, and interference between internal molds and ...

Resistance exercise breaks during prolonged sitting augment the blood flow response to a subsequent oral glucose load in sedentary adults

open access: yesExperimental Physiology, EarlyView.
Abstract Sitting‐induced impairments in postprandial blood flow are an important link between sedentary behaviour and cardiometabolic disease risk. The objective of this work was to examine the effects of resistance exercise breaks (REB) performed every 30 min during an otherwise sedentary 3‐h period on the vasodilatory response to a subsequent oral ...

Study on the Strength Characteristics of Ion-Adsorbed Rare Earth Ore Under Chemical Leaching and the Duncan–Chang Model Parameters

open access: yesMetals
Ionic rare earths are extracted from primary sources by the in situ chemical leaching method, where the type and concentration of leaching agents significantly affect the mechanical properties and microstructure of the ore body.

Energetic microdomains and the vascular control of neuronal and muscle excitability: Toward a unified model

open access: yesThe Journal of Physiology, EarlyView.
Abstract figure legend The capillary–mitochondria–ion channel (CMIC) axis scales structural resources to match functional workload. (Left) In settings of restricted energetic capacity (e.g. cortical neurons), sparse capillary networks and modest mitochondrial pools set a lower energetic ceiling, sufficient to support phasic, low‐workload excitability.

Experimental study on bearing mechanical characteristics of “hyperbolic”coal samples

open access: yesMeitan kexue jishu
After the underground coal gasification is completed, a hyperbolic shaped coal pillar is formed between the two cavities to support the overlying rock and ensure the safety and stability of the gasification area.

Physiological mechanisms underlying enhanced performance with blood flow restriction training: neuromuscular, vascular and metabolic adaptations

open access: yesThe Journal of Physiology, EarlyView.
Abstract figure legend We investigated how 6 weeks of dynamic knee‐extensor interval training with blood flow restriction (BFR‐leg) and without (CTRL‐leg) impacts performance and its mechanisms using non‐invasive methods. Specifically, we used gold‐standard methods to assess neuromuscular function, vascular function using Doppler ultrasound, and near ...

Illness Perceptions in Psychiatric Disorders: Assessing Differences and Associations With Symptom Severity

open access: yesEuropean Eating Disorders Review, Volume 34, Issue 2, Page 398-410, March 2026.
ABSTRACT Objectives This study investigated the influence of illness perceptions (IPs) on clinical severity across Major Depressive Disorder (MDD), Anorexia Nervosa (AN), Generalised Anxiety Disorder (GAD), Social Anxiety Disorder (SAD), and Panic Disorder (PD), and compared the IPs across these conditions.
