Pathological changes of skin will change the tissue's birefringence and structure, which can be measured by the polarization and spectral changes of the tissue's scattering light. Light-scattering spectropolarimetry is an effective tool to measure these features for quantitative pathology analysis. An epithelial tissue imaging spectropolarimeter is proposed to acquire the spectral, polarimetric...

Hutchinson-Gilford progeria syndrome is an extremely rare condition with features of premature and accelerated aging. The pattern of inheritance is unclear, although autosomal dominant mutations have been proposed. The disease presentation is usually in infancy and early childhood with a characteristic phenotype of short stature, abnormal skin and nail, beaked nose, loss of subcutaneous f...

the shear strength and shear energy per unit area, as well as the force and energy required for picking flowers, are important parameters in the design and development of harvesting mechanisms. in this study, shear strength and shear energy per unit area of saffron (crocus sativus l.) stems were determined at different bevel angles and shear velocities. the force and energy required for picking...

The term body-focused repetitive behaviors (BFRBs) refers to a group of recurrent, problematic, destructive behaviors directed toward the body, including hair-pulling, skin-picking, and nail-biting. Individuals with BFRBs report diminished control over the behavior and a range of physical and psychological sequelae. Recent research on psychological models for BRFBs has investigated the role of ...

Recently, the minimum number of reticulation events that is required to simultaneously embed a collection P of rooted binary phylogenetic trees into a so-called temporal network has been characterized in terms of cherry-picking sequences. Such a sequence is a particular ordering on the leaves of the trees in P. However, it is well-known that not all collections of phylogenetic trees have a cher...
