Abnormal, excessive stresses acting on articular joint surfaces are speculated to be one of the causes for joint degeneration. However, articular surface stresses have not been studied systematically, since it is technically difficult to measure in vivo contact areas and pressures in dynamic situations. Therefore, we implemented a numerical model of articular surface contact using accurate surf...

The joint probability distribution of exciton energies and transition dipole moments determines a variety of optical observables in disordered exciton systems. We demonstrate numerically that this distribution obeys a one-parameter scaling, originating from the fact that both the energy and the dipole moment are determined by the number of coherently bound molecules. A universal underlying dist...

Ankylosing spondylitis (AS) is a chronic systemic inflammatory disorder. It primarily affects the axial skeleton through involvement of the peripheral joint scan occurs. Temporomandibular joint (TMJ) involvement in AS varies from 4% to 35%. Here, we present a case of a 35-year-old male, follow-up of AS from last 8 years on nonsteroidal anti-inflammatory drugs, presented with fresh complaints of...

Osteoarthritis (OA) is the most pervasive joint disorder impacting over millions of people each year. OA normally affects larger weight-bearing joints, with knees being prevalent. It anticipated to affect 67 million by 2030.

The focus of this study is using data glove to practice Joint attention skill in virtual reality environment for people with pervasive developmental disorder (PDD). The virtual reality environment provides a safe environment for PDD people. Especially, when they made errors during practice in virtual reality environment, there is no suffering or dangerous consequences to deal with. Joint attent...

Recent work has identified the transition from adolescence to young adulthood as a period with distinct characteristics that is important for understanding of human development. Self-esteem plays a critical role in this developmental process. We use self-esteem data measured at mean ages 13, 16 and 22, and anxiety disorder diagnosis at mean age of 33 to examine the impact of development of self...
