Thermal properties of K3Li2−x Nb5+x O15±δ crystals
Physics of the Solid State, 2003The unit-cell parameters of the nonlinear crystal K3Li2−xNb5+xO15±δ were measured with x-ray diffraction in the temperature region 80–300 K. The room-temperature parameters of the crystal of this composition are a=12.599±0.001 and c=4.018±0.001 A.

Right frontotemporal activation by tonal memory in dyslexia, an O15 PET study
Biological Psychiatry, 1994A prior study documented the failure of dyslexic men to activate left temporoparietal cortex during phonologic processing. Because of reports of an anomalous right planum temporale in developmental dyslexia, the functional implications of which are unknown, this study examined the ability of dyslexics to activate right temporal cortex.

O15-3 Reality and aetiology: target parameters in occupational epidemiology
Oral Session 15 – Statistical Methods, 2016The determination of appropriate standards for workplace exposure requires accurate estimation of the health effects. This will sometimes require adjustment for the Healthy Worker Survivor Effect (HWSE) using g-methods, which can adjust for the time-varying confounding on the causal pathway that characterises this bias.

Optical fiber feeder for microcellular mobile communication systems (H-O15)
IEEE Journal on Selected Areas in Communications, 1993The authors investigate the feasibility of using an optical fiber feeder for microcellular mobile communication systems. The optical feeder enables compact and low-cost base stations, easy radio channel control, and flexible mobile communication systems.

O15 Transcriptomic profiling reveals regulators of dermal fibroblast state switching
British Journal of DermatologyAbstract Introduction and aims Fibroblasts, the major cell population in connective tissue, are the guardians of the extracellular matrix homeostasis. In adult tissue they exist in a quiescent state that can persist for years, but upon tissue injury, they become rapidly activated and re-enter the cell
