A range of risk factors lead to opioid use and substance-related problems (SRP) including childhood maltreatment, elevated impulsivity, and psychopathology. These constructs are highly interrelated such that childhood maltreatment is associated with elevated impulsivity and trauma-related psychopathology such as posttraumatic stress disorder (PTSD), and impulsivity-particularly urgency-and PTSD...

The roles of shame and attribution style in developing posttraumatic stress disorder (PTSD) were examined among 172 Japanese university women with negative sexual experiences (NSEs) using a structural equation model. ‘‘Shame’’ directly predicted PTSD, whereas ‘‘Internal Attribution’’ and ‘‘External Attribution’’ did not. The effect of Internal Attribution on PTSD was mediated by Shame. In a sim...

OBJECTIVE The high degree of heterogeneity in the development of depression under stress is unaccounted for in traditional statistical modeling. We employ growth mixture modeling to identify classes of individuals at highest risk of depression under stress. METHOD Medical internship was used as a prospective stress model. Interns from US residency programs completed demographic, psychological...

This paper presents the results of numerical modeling using the finite element method of three implants. Geometric models of individual parts of the analyzed system (implant, abutment and screw) and the standard models of the bone and the crown were built in the Ideas NX environment. On the basis of real geometric models the fully three-dimensional numerical models were built. The calculations ...

Study on the seismic behavior of piled rafts and pile groups while the same amount of construction material and excavation is used in their construction, are the main objective of this research. The process where the raft interaction with soil can affect the seismic response and stress distribution is also discussed in the current study. By means, ABAQUS software was applied for the finite elem...

Originally formulated to understand the recurrence of depressive disorders, the stress generation hypothesis has recently been applied in research on anxiety and externalizing disorders. Results from these investigations, in combination with findings of extensive comorbidity between depression and other mental disorders, suggest the need for an expansion of stress generation models to include t...

introduction: attachment of blood and tissue cells to the extracellular matrix (ecm) is done with the help of specific joints, which are made between cells’ receptors and matrixes’ ligands. this interaction is vital for many biological activities such as cell migration, cancer development, and wound healing. the purpose of this study is to model a 3-dimensional cell by abaqus commercial softwar...

COMPUTATIONALMODELING of mechanical behavior during solidification is becoming more important. Thermal and microstructural simulations alone are insufficient to predict the quality of the final product that is desired by the casting industry. Accurate calculation of displacements, strains, and stresses during the casting process is needed to predict residual stress and distortion and defects su...

Negatively twisted DNA is essential to many biological functions. Due to torsional stress, duplex DNA can have local, sequence-dependent structural defects. In this work, a thermodynamic model of DNA was built to qualitatively predict the local sequence-dependent mechanical instabilities under torsional stress. The results were compared to both simulation of a coarse-grained model and experimen...

[1] We discuss the impact of uncertainties in computed coseismic stress perturbations on the seismicity rate changes forecasted through a rateand state-dependent frictional model. We aim to understand how the variability of Coulomb stress changes affects the correlation between predicted and observed changes in the rate of earthquake production. We use the aftershock activity following the 1992...
