In this paper, we model the reflectance of the lunar regolith by a new method combining Monte Carlo ray tracing and Hapke's model. The existing modeling methods exploit either a radiative transfer model or a geometric optical model. However, the measured data from an Interference Imaging spectrometer (IIM) on an orbiter were affected not only by the composition of minerals but also by the envir...
Introduction: With NASA’s return to the Moon, the determination of safe landing sites for future robotic and human missions is crucial, and rock abundance will be important criteria for landing site selection. Thermal inertias derived from remote sensing in the thermal infrared is a powerful technique for assessing rock abundance for the purpose of landing site selection on Mars [1,2]. Rocks a ...
The Visible Infrared Imager Radiometer Suite (VIIRS) is one of five instruments on-board the Suomi National Polarorbiting Partnership (NPP) satellite that launched from Vandenberg Air Force Base, Calif., on Oct. 28, 2011. VIIRS has been scheduled to view the Moon approximately monthly with a spacecraft roll maneuver after its NADIR door open on November 21, 2011. To reduce the uncertainty of th...
Based on a data sample of an integrated luminosity of 57.4 fb at the Υ(4S) resonance taken with the BABAR detector using the SLAC PEP-II asymmetric-energy B-Factory, hadronic decays of B meson with the final states D and three pions are studied. The study is performed by fully reconstructing the exclusive decays of B → Da1(1260) and the non-resonant modes B → D ρπ and B → Dπππ. The current stat...

The optical properties of lunar softs are different than those of rocks from which they are derived. As a consequence of lunar space weathering, soils are darker and exhibit a distinctive red-sloped continuum and weaker mineral absorption bands. The accumulation of dark glass-welded aggregates (agglutinates) has been thought to account for these optical effects of space weathering on lunar soil...
[1] The Moon Mineralogy Mapper (M), a high‐resolution, high‐precision imaging spectrometer, flew on board India’s Chandrayaan‐1 Mission from October 2008 through August 2009. This paper describes some of the spatial sampling aspects of the instrument, the planned mission, and the mission as flown. We also outline the content and context of the resulting Level 1B spatial products that form part ...
The United Kingdom was among the first countries to introduce a salt reduction program in 2003 reduce cardiovascular disease (CVD) incidence risk. Despite its initial success, has stalled recently and is yet achieve national international targets. We used age- sex-stratified intake of 19 64 years old participants National Diet Nutrition Surveys 2000 2018 multistate life table model assess effec...
Introduction: The presence of garnet in the lunar mantle has been debated from many years (e.g., [1-3]). Data from the Apollo seismic network were unable to unambiguously resolve a garnet signature in the lower mantle. For example, higher seismic velocities in the lunar mantle (>500 km) could be indicative of an increased proportion of Mg-rich olivine [2,4], or be due to the presence of garnet ...
Behaviours of several animal species have been linked to lunar periodicity. Evidence for such links in humans is weak; however, recently, shorter sleep duration was reported around full moon in two small samples of adults. As restrictions in sleep duration have been shown to adversely affect glucose regulation and physical activity to improve glucose regulation, one could speculate that cardiom...
