Evidence points to heightened physiological arousal in response to acute stress exposure as both a prospective indicator and a core characteristic of posttraumatic stress disorder (PTSD). Because females may be at higher risk for PTSD development, it is important to evaluate sex differences in acute stress reactions. This study characterized sex differences in cardiovascular and subjective stre...

Expressive speech synthesis has received increased attention in recent times. Stress (or pitch accent) is the perceptual prominence within words or utterances, which contributes to the expressivity of speech. This paper summarizes our contribution to Mandarin expressive speech synthesis. A novel hierarchical stress modeling and generation method for Mandarin is proposed and further integrated i...

Introduction: Introduction: Few studies have investigated the distribution of stress around implants. In this study the distribution of stress in bones around implants was investigated in five overdenture (OD) treatment designs including OD-1, OD-2, OD-3, OD-4 and OD-5. Materials and methods: The Catia modeling software was used in order to simulate the tooth/implant model and bone. First, the ...

PURPOSE Patellofemoral (PF) pain is common among athletes and may be caused by increased subchondral bone stress as a result of increased stress in the cartilage of the femur or patella. This article presents a modeling pipeline to estimate in vivo cartilage stress in the PF joint. METHODS The modeling pipeline uses the finite element method to calculate stresses and strains in the PF joint c...

Objectives: The current study was designed to explain the causal relationship between irrational beliefs and the marital satisfaction based on the mediating role of the conflict resolution behavior and the marital stress. Methods: The research had a descriptive-correlational design and the statistical population of the study consisted of all married men and women living in Tehran in 1398, fro...

in this research, a new mathematical modeling on strength changes due to reservoir elastic stresses across the preexisting fault plane is introduced. the method has been applied to the dalpari fault, which is one of the potential seismic sources in the vicinity of the karkheh reservoir. in this method the distribution of total stress across the fault cannot be determined because the initial str...

In order to reduce the stress caused to patients by conventional methods of modeling using computed tomography (CT) or magnetic resonance imaging (MRI), an optical modeling process has been developed for extraoral defects and body areas. The selected body part is digitized using optical 3-coordinate measuring technology, providing an extensive data record. This is adapted for further use by equ...

Coupling flow and deformation is of interest when modeling settling due to pumping water or oil, compaction due to construction, or, in other fields, modeling soft tissue, bones, or man-made porous materials. The modeling usually combines the Conservation of Mass equations for all phases, Darcy’s law for flow, the Terzaghi’s principal of effective stress, and a stress-strain relation. Here we d...

Friction stir welding (FSW) is a new method that the joining is carried out by friction between two metals and heat creation. The stress concentration phenomena in welded joint cause the stress increasing in welded zone. In this research, modeling and analysis of similar junction of IN718 and Mar-M247 and non-similar junction of IN718-Mar-M247 superalloys were performed by ANSYS Software and fi...
