IEEE Access, 2018 How do cellists' postural movements influence timbre quality during instrumental performance? If this question seems complex at a first glance partly due to specific motor synergies for each musician, some principles of postural organization are believed

, 2015 The volume of air that goes in and out of a musical instrument's sound hole is related to the sound hole's contribution to the volume of the sound. Helmholtz's result for the simplest case of steady flow through an elliptical hole is reviewed. Measurements on multiple holes in sound box geometries and scales relevant to real musical instruments ...

Advanced Functional Materials, EarlyView.Epitaxial piezoelectric α‐quartz/Si BioNEMS sensors, made using soft chemistry, effectively detect the Chikungunya virus. They have a mass sensitivity of 205 pg Hz−1 in liquid and can detect the virus at a limit of 9 ng mL−1. This development enables high‐frequency mass devices for point‐of‐care testing in healthcare and other electronic applications ...

Frontiers in Immunology, 2014 THE SILENCE OF HEALTH “Health is life lived in the silence of the organs” wrote the French surgeon Rene Leriche in 1936, a concept later adopted and further developed by the physician and philosopher Georges Canguilhem (1). Albeit certainly resonant with the experience of health defined as the state of well being perceived by an individual, this ...

Kidney Stone Dissolution By Tetherless, Enzyme‐Loaded, Soft Magnetic Miniature Robots
Advanced Healthcare Materials, EarlyView.Wireless magnetic robots are developed for kidney stone dissolution. The robots navigate through a urinary tract model from bladder and ureter to renal pelvis with the help of external magnetic fields. The filaments are loaded with urease enzyme which catalyzes urea to carbon dioxide and ammonia, thereby increasing pH to basic regime and supporting ...

Osong Public Health and Research Perspectives, 2014 Can you remember your old schooldays? For some reason, we remember the old good days as being especially beautiful. All the shrubs on campus were in blossom and the trees were green. The grass was dotted with dandelions. Everyone was happy and carefree, for the vacation was just about to begin. With that to look forward to, no-one was worried about the

Advanced Healthcare Materials, EarlyView.The covalent binding of dexamethasone to the surface of polyimide represents the electrically inert part of implantable intraneural devices. This ensures a sustained release of the drug for 9 weeks. In vitro and in vivo tests confirm the reduction of the foreign body reactions and the improved biocompatibility of dexamethasone functionalized polyimide.

Timbre differences of an individual voice in solo and in choral singing
Archives of Acoustics, 2015 The object of the study was to analyze differences between solo and choral production of the same singer. Six female and six male chorus singers sang the same musical material solo, in vocal groups, and as a choir.
