The ventral scales of Dinodon rufozonatum were investigated to understand the outstanding tribological adaptability in various environments. coefficient friction (COF) was measured and changed with contact conditions. It discovered that COF under water-lubrication conditions (WLC) larger than dry (DC). More interestingly, increased first then decreased as substrate roughness reduced. abrasion m...

OBJECTIVE This study evaluated the efficacy of a spiritually integrated treatment (SIT) for subclinical anxiety in the Jewish community. METHOD One hundred and twenty-five self-reported religious Jewish individuals with elevated levels of stress and worry received SIT (n=36), progressive muscle relaxation (PMR, n=42), or a waitlist control condition (WLC, n=47). SIT and PMR participants acces...

Force-extension curves (FECs), which quantify the response of a variety of biomolecules subject to mechanical force (f), are often quantitatively fit using worm-like chain (WLC) or freely jointed chain (FJC) models. These models predict that the chain extension, x, normalized by the contour length increases linearly at small f and at high forces scale as x ~ (1 - f(-α)), where α = 0.5 for WLC a...

The wormlike-chain (WLC) model is widely used to describe the energetics of DNA bending. Motivated by recent experiments, alternative, so-called subelastic chain models were proposed that predict a lower elastic energy of highly bent DNA conformations. Until now, no unambiguous verification of these models has been obtained because probing the elasticity of DNA on short length scales remains ch...

Employed workers often have family responsibilities such as childcare or homemaking. This dual burden may increase work-related health problems, particularly if there are conflicts between work and family responsibilities. This study assessed whether difficulty in work-life balance is associated with musculoskeletal disorders (MSD) among Korean employees. Data from the population-based Korean W...

Compared the effects of 2 psychotherapies based on divergent conceptualizations of depression in later life. Seventy-five older adults diagnosed with major depressive disorder were assigned randomly to problem-solving therapy (PST), reminiscence therapy (RT), or a waiting-list control (WLC) condition. Participants in PST and RT were provided with 12 weekly sessions of group treatment. Dependent...
