Sex ratio alterations related to environmental factors occur in several mammals, but no mechanism has been identified to explain the adjustment. Intrauterine position (IUP) may provide the context in which such alterations occur. Previous studies on house mice and gerbils reveal that the position of a fetus in the uterus in relation to the sex of its neighbors influences its later anatomy, phys...

This paper examines the surface-related capacitance C/S of carbons with average micropore widths between 0.73 and 1.80 nm, using 1-2M H2SO4, 6M KOH and 1M (C2H5)4NBF4 in acetonitrile as electrolytes. Following corrections for pseudocapacitance effects for the aqueous electrolytes and the use of an average surface area suggested by independent techniques, different from the BET area, it appears ...

PcG proteins mediate heritable transcriptional silencing by generating and recognizing covalent histone modifications. One conserved PcG complex, PRC2, is composed of several proteins including the histone methyltransferase (HMTase) Ezh2, the WD-repeat protein Eed, and the Zn-finger protein Suz12. Ezh2 methylates histone H3 on lysine 27 (H3K27), which serves as an epigenetic mark mediating sile...

This paper proposes a stereo vision-based algorithm for objects’ depth estimation suggested for guiding visually impaired people. The proposed algorithm is a first step towards a complete system designed for warning visually impaired persons to avoid in front obstacles at a reasonable distance (1m-2m). First, the left and right images are captured by a stereo vision camera. After preprocessing ...
