The human body consists of many different soft biological tissues that exhibit diverse microstructures and functions and experience diverse loading conditions. Yet, under many conditions, the mechanical behaviour of these tissues can be described well with similar nonlinearly elastic or inelastic constitutive relations, both in health and some diseases. Such constitutive relations are essential for performing nonlinear stress analyses, which in turn are critical for understanding physiology, pathophysiology and even clinical interventions, including surgery.

Neuroticism predicts behaviors symptomatic of behavior dysregulation. One idea is that Neuroticism encompasses deficits in executive functioning; despite this link being empirically substantiated, it remains poorly understood. If Neuroticism is associated with executive functioning deficits due to it activating impulsivity in response to negative emotion, and if Negative Urgency (NU) is the specific aspect of emotional impulsivity that amplifies impulsivity in response to negative emotion, then Neuroticism's link to executive functioning deficits should be enhanced in individuals higher in NU.

A Narrative Persuasion Approach to Promoting COVID-19- Related Policy Support.

J Health Commun

January 2025

School of Criminal Justice, Forensic Science, and Security, University of Southern Mississippi, Hattiesburg, Mississippi, USA.

Communication scholars warn against focusing on individual behaviors when discussing health issues, arguing that doing so can reduce affect and policy support. Although COVID-19 outcomes are linked to structural barriers to treatment, policy interventions appear to improve outcomes for vulnerable groups. Thus, strategic messages must promote public understanding of social determinants and policy support related to COVID-19.

Understanding factors influencing the spatio-temporal patterns of apex predators is prerequisite for their conservation. We studied space use and diel activity of tigers () in response to prey availability and anthropogenic activities with trail cameras in Nepal during December 2022-March 2023. We used hierarchical occupancy models to evaluate how prey availability (space use of prey species) and anthropogenic activities (number of humans and livestock) contributed to the tigers' space use, while accounting for landscape effects on their detection probability.

Environmental conditions influence the maternal deposition of hormones into eggs, which is hypothesized to adaptively modify developmental outcomes in offspring. However, most ecosystems harbour environmental contaminants capable of disrupting endocrine signaling, and maternal exposure to these compounds has the potential to further alter offspring traits. Studies rarely examine maternally derived hormones and contaminants along with offspring phenotypes, and we know little about their interrelationships and potential interactions.

Population variability across geographical ranges: perspectives and challenges.

Proc Biol Sci

January 2025

Department of Biological Sciences, University of South Carolina, Columbia, SC 29208, USA.

Populations fluctuate over time and across geographical space, and understanding how different factors contribute to population variability is a central goal in population ecology. There is a particular interest in identifying trends of population variability within geographical ranges as population densities of species can fluctuate substantially across geographical space. A common assumption is that populations vary more near species geographical range edges because of unsuitable environments and higher vulnerability to environmental variability in these areas.

The signals that mediate mate choice can be complex, comprising multiple components, and understanding how complex signals evolve under sexual selection has been the focus of much study. However, open questions still remain about the role of the female's sensory and perceptual processes in shaping the evolution of complex signals. Male green swordtails have an elongated caudal fin that comprises colour, length and a black melanic margin; females prefer males with larger bodies, longer swords and complete black sword margins.

Social learning preserves both useful and useless theories by canalizing learners' exploration.

Proc Biol Sci

January 2025

Human Behaviour and Cultural Evolution Group, Centre for Ecology and Conservation, University of Exeter, Penryn TR10 9FE, UK.

In many domains, learning from others is crucial for leveraging cumulative cultural knowledge, which encapsulates the efforts of successive generations of innovators. However, anecdotal and experimental evidence suggests that reliance on social information can reduce the exploration of the problem space. Here, we experimentally investigate the extent to which cultural transmission fosters the persistence of arbitrary solutions in a context where participants are incentivized to improve a physical system across multiple trials.
