We generalize the elegant bijective proof of the Chung Feller theorem from the paper of Young-Ming Chen [The Chung-Feller theorem revisited, Disc. Math. 308 (2008), 1328–1329].

The Shapley Concentration is the richest supercluster of clusters in the nearby universe and its core is a remarkable complex formed by the ACO clusters A3558, A3562 and A3556, and by the two minor groups SC 1327-312 and SC 1329-314. This structure has been studied in various wavelength bands, revealing that it is probably dynamically very active. In this paper we present 174 new galaxy redshif...

mals, and they have various physiological roles. D-Aspartate is present in the central nervous system and various neuroendocrine cells, which include a subset of satellite and basket cells in the cerebellum, adrenal chromaffin cells, pituitary gland cells, Leydig cells and pinealocytes. D-Aspartate is believed to modulate neuroendocrine functions in either an intercellular or intracellular mann...

A survey of 1329 relatives of 139 patients with coeliac disease demonstrated an overall increase of cancer deaths particularly in women, but this did not quite reach 5 percent significance in men. Evidence is insufficient to determine whether this was due to the occurrence of cancer in relatives with undetected coeliac disease or to the operation of independent factors.
