[1] High-alumina (HA) mare basalts are a unique group of the lunar sample collection. Sample geochemistry indicates that these basalts are derived from sources composed of late-stage cumulates from the Lunar Magma Ocean (LMO). Their aluminous nature suggests their sources contained significant plagioclase, which has implications regarding the efficiency of plagioclase separation from earlier fo...

Locations and compositions of mare ponds in South pole-Aitken (SPA) basin are correlated to the structure of the SPA impact basin. The coverage of mare emplacements indicates that, inside the inner ring, the floor is relatively filled with mare deposits, whereas, in the regions of just inside the middle and outer rings, some mare extrusions exist. The lack of Hi-Ti basalt in mare ponds could re...

Mapping rearrangement (MaRe) for the hybrid ARQ (HARQ) based on the parallel concatenated trellis coded modulation (PCTCM) is analyzed. We demonstrate that the performance of the PCTCM receiver is intrinsically limited by the MaRe design and we propose a new mapping scheme to fit the structure of PCTCM transceivers. Depending on the HARQ scenarios, the proposed scheme offers gains between 0.1 a...

Successful initiation and continuation of lactation in the postpartum mare depends on normal hormonal activity and a lack of any inhibitory influences on the mare. Impediments to adequate lactation include underlying systemic disease of the mare, pathology of the mammary gland, malnutrition, and diminished neonatal vigor reducing normal suckling activity.

Ancient lunar volcanic deposits, known as cryptomaria, have been detected by remote telescopic and orbital measurements since the 1970s. Cryptomaria are most easily identified by the presence of darkhalo impact craters and are associated with a mare basalt mineralogy, which is indicated by two pyroxene spectral absorption features near 1 μm and 2 μm in the visible to near-infrared (VNIR) wavele...

The Maf family of proteins are a subgroup of basic region-leucine zipper (bZIP) transcription factors, which recognize a long palindromic DNA sequence [TGCTGAC(G)TCAGCA] known as the Maf recognition element (MARE). Interestingly, the functional target enhancer sequences present in the alphaA-crystallin gene contain a well-conserved half-site of MARE rather than the entire palindromic sequence. ...

Introduction: Many questions regarding the petrogenesis of mare basalts remain unresolved. Trace element and isotope geochemists tend to view the range of mare basalt compositional groups as independent primary magmas and develop mantle melting models to explain the compositional diversity [e.g. 1, 2, 3]. On the other hand, petrologists view the mare basalt suites as non-primary and suggest tha...

Radar images at 70 cm wavelength show 4–5 dB variations in backscatter strength within regions of relatively uniform spectral reflectance properties in central and northern Mare Serenitatis, delineating features suggesting lava flow margins, channels, and superposition relationships. These backscatter differences are much less pronounced at 12.6 cmwavelength, consistent with a large component o...

[1] We use polarimetric radar observations to study the distribution, depth, and embedded rock abundance of nearside lunar pyroclastic deposits. Radar images were obtained for Mare Vaporum and the southern half of Mare Serenitatis; the imaged areas contain the large Rima Bode, Mare Vaporum, Sulpicius Gallus, and Taurus-Littrow pyroclastic deposits. Potential pyroclastic deposits at Rima Hyginus...

Newly obtained near-infrared reflectance spectra for features on or near the Aristarchus Plateau demonstrate he diversity of compositions in the region. t!ighland units are of three probable compositions: a feldspar and elinopyroxene assemblage; a probable clinopyroxene, olivine, and possibly feldspar assemblage; and an assemblage composed of olivine or olivine and feldspar. The feldspar-elinop...
