By following the Wittgensteinian view that the sense of an ethical term such as ＂nature＂（xing ＇~） should be understood through an examination of its function in its actual philosophical context, this article takes a look at the notion ofxing in the Mencius from an alternative perspective. Proceeding from this perspective, it re-examines the view that xing in the Mencius should be understood in biological terms. A discussion of xing in relation to the ＂Why be moral？＂ question follows. I then offer an alternative interpretation of Mencius＇ ethics by focusing on the meaning of the ethical particulars. Contrary to common perception, I argue that Mencius＇ theory of human nature （renxing）k ＇~） need not occupy a central place in his moral philosophy; the ultimate foundation of Mencius＇ moral philosophy lies in the meaning or sense of morality. through participating in concrete, ethical thinking and by paying attention to the ethical particulars, human beings develop their grasp of moral and ethical meaning.

SPEAR3 is a third-generation synchrotron light source storage ring, about 234 meters in *** meet the beam stability requirement, our goal is to ultimately achieve an orbit variation（relative to the photon beam lines） of less than 10% of the beam size, which is about 1 micron in the vertical plane. Hydrostatic leveling system（HLS） measurements show that the height of the SPEAR3 tunnel floor can vary by tens of microns daily without thermal insulation improvements. We present an analysis of the HLS data that shows that adding thermal insulation to the concrete walls of the storage ring tunnel dramatically decreased diurnal tunnel floor motion.

Hybridization plays a significant role in biological evolution. However, it is not clear whether ecological contingency differentially influences likelihood of hybridization, particularly at ecological margins where parental species may exhibit reduced fitnesses. Moreover, it is unknown whether future ecosystem change will increase the prevalence of hybridization. Ficus heterostyla and F. squamosa are closely related species co-distributed from southern thailand to southwest China where hybridization, yielding viable seeds, has been documented. As a robust test of ecological factors driving hybridization, we investigated spatial hybridization signatures based on nuclear microsatellites from extensive population sampling across a widespread contact range. Both species showed high population differentiation and strong patterns of isolation by distance. Admixture estimates exposed asymmetric interspecific gene *** of hybridization increase significantly towards higher latitude zones, peaking at the northern climatic margins. Geographic variation in reproductive phenology combined with ecologically challenging marginal habitats may promote this phenomenon. Our work is a first systematic evaluation of such patterns in a comprehensive, latitudinally-based clinal context, and indicates that tendency to hybridize appears strongly influenced by environmental conditions. Moreover, that future climate change scenarios will likely alter and possibly augment cases of hybridization at ecosystem scales.

We present resolved Giant Metrewave Radio telescope H I observations of the high gas-phase metallicity dwarf galaxy WISEA J230615.06+143927.9(z = 0.005)(hereafter J2306) and investigate whether it could be a tidal Dwarf Galaxy(tDG) candidate. tDGs are observed to have higher metallicities than normal dwarfs. J2306 has an unusual combination of a blue g-r color of 0.23 mag, irregular optical morphology and high-metallicity(12 +log(O/H) = 8.68 ± 0.14), making it an interesting galaxy to study in more detail. We find J2306 to be an H I rich galaxy with a large extended, unperturbed rotating H I disk. Using our H I data we estimated its dynamical mass and found the galaxy to be dark matter(DM) dominated within its H I radius. the quantity of DM, inferred from its dynamical mass, appears to rule out J2306 as an evolved tDG. A wide area environment search reveals J2306 to be isolated from any larger galaxies which could have been the source of its high gas metallicity. Additionally, the H I morphology and kinematics of the galaxy show no indication of a recent merger to explain the *** detailed optical spectroscopic observations of J2306 might provide an answer to how a seemingly ordinary irregular dwarf galaxy achieved such a high level of metal enrichment.
