The inversion of lidar returns from homogeneous atmospheres has been done customarily through the well-known slope method. The logarithmic operation over the range-corrected and system-normalized received signal used in this method introduces a bias in the statistics of the noise-affected processed signal that can severely distort the estimates of the atmospheric attenuation and backscatter coe...

Viruses are known to tolerate wide ranges of pH and salt conditions and to withstand internal pressures as high as 100 atmospheres . In this paper we investigate the mechanical properties of viral capsids, calling explicit attention to the inhomogeneity of the shells that is inherent to their discrete and polyhedral nature. We calculate the distribution of stress in these capsids and analyze th...

one grotesque catfish specimen was collected in zhangjiang river (upper reach of a secondary tributary of hongshuihe river) in libo county, guizhou province, china. this specimen bears surprising character of four dorsal fins, which have not appeared in any other silurid fishes. but other morphological characters, such as two pairs of barbels, lower jaw projecting beyond upper jaw, the first do...

arguing that human rights treaties by their nature are different from other international agreements, this article deals mainly with such questions as succession of states in respect of human rights treaties and reservations to such instruments.  in contrast to other treaties, which are generally “inter-states exchange of interests”, human rights documents are protective instruments according t...

Considering its richness, Greek and Roman art remains distinctly under-utilized in medical-historical studies of the period. It poses, of course, substantial methodological problems, as Grmek and Gourevitch outline in the introductory sections of their welcome overview of the pathological side of this subject. There is a realist strand in ancient art (particularly marked in the Roman era, with ...
