The viscoelastic Kelvin-Voigt model is considered within the context of quasi-static deformations and generalized with respect to a nonlinear constitutive response within the framework of limiting small strain. We consider a solid possessing a crack subject to stress-free faces. The corresponding class of problems for strain-limiting nonlinear viscoelastic bodies with cracks is considered within a generalized formulation stated as variational equations and inequalities. Its generalized solution, relying on the space of bounded measures, is proved rigorously with the help of an elliptic regularization and a fixed-point argument.

In the United States, the COVID-19 Pandemic caused many autistic adults to be fearful and worried about their health. There is a lot of research that says that when autistic adults experience health distress it can worsen their mental health. We do not know, however, what might explain how experiencing health distress negatively affects mental health.

This study aimed to explore contextual elements of the cancer experience that are consistently distressing and/or psychologically traumatic, as well as explore perceptions of Accelerated Resolution Therapy® (ART®) and its influence on the cancer experience. Using a qualitative descriptive design, semi-structured interviews were completed by 12 participants following the completion of ART. Interview data were analyzed using content analysis to identify major themes and patterns.

Recently, exposure to sounds with ultrasound (US) components has been shown to modulate brain activity. However, the effects of US on emotional states remain poorly understood. We previously demonstrated that the olfactory bulbectomized (OBX) rat depression model is suitable for examining the effects of audible sounds on emotionality.

This study aims to explore the mechanism behind the influence of stress on gas adsorption by coal during deep mining and improve the accuracy of gas disaster prevention and control. To achieve this aim, thermodynamic analysis was conducted on the process of gas adsorption by loaded coal, and modified thermodynamic model proposed by previous scholars. It is found that stress plays an important role in gas adsorption by coal.

Decades of research hold that empathy is a multifaceted construct. A related challenge in empathy research is to describe how each subcomponent of empathy uniquely contributes to social outcomes. Here, we examined distinct mechanisms through which different components of empathy-Empathic Concern, Perspective Taking, and Personal Distress-may relate to prosociality.
