High Precision Refraction Measurements By Solar Imaging During Occultation: Results From Sofie
(Optical Society of America, 2009-09-01)A new method for measuring atmospheric refraction angles is presented, with in-orbit measurements demonstrating a precision of +/-0.02 arcsec (+/-0.1 mu rad). Key advantages of the method are the following: (1) Simultaneous ... -
High quality factor silica microspheres functionalized with self-assembled nanomaterials
(Optical Society of America, 2013-09-01)With extremely low material absorption and exceptional surface smoothness, silica-based optical resonators can achieve extremely high cavity quality (Q) factors. However, the intrinsic material limitations of silica (e. ... -
High quality Ge thin film grown by ultrahigh vacuum chemical vapor deposition on GaAs substrate
(AIP Publishing, 2011-04-01)High-quality epitaxial Ge films were grown on GaAs substrates by ultrahigh vacuum chemical vapor deposition. High crystallinity and smooth surface were observed for these films by x-ray diffraction, transmission electron ... -
High-fat or ethinyl-oestradiol intake during pregnancy increases mammary cancer risk in several generations of offspring
(Nature Publishing Group, 2012-01-01)Environmental factors can influence one's susceptibility to cancer, but it is not clear whether such an influence extends beyond the directly exposed generations. Here, feeding pregnant rats with a high-fat diet or a hormone ... -
High-frequency irreversible electroporation (H-FIRE) for non-thermal ablation without muscle contraction
(2011-11-21)Background Therapeutic irreversible electroporation (IRE) is an emerging technology for the non-thermal ablation of tumors. The technique involves delivering a series of unipolar electric pulses to permanently destabilize ... -
High-frequency irreversible electroporation is an effective tumor ablation strategy that induces immunologic cell death and promotes systemic anti-tumor immunity
(2019-06)Background: Despite promising treatments for breast cancer, mortality rates remain high and treatments for metastatic disease are limited. High-frequency irreversible electroporation (H-FIRE) is a novel tumor ablation ... -
High-performance biocomputing for simulating the spread of contagion over large contact networks
