Cetotheriidae are an iconic, nearly extinct family of baleen whales (Mysticeti) with a highly distinct cranial morphology. Their origins remain a mystery, with even the most archaic species showing a variety of characteristic features. Here, we describe a new species of archaic cetotheriid, Tiucetus rosae, from the Miocene of Peru. The new material represents the first mysticete from the poorly...

Zeugophora varians Crotch and the family Megalopodidae are newly recorded for New Brunswick, Canada. Twenty-eight species of Chrysomelidae are newly recorded for New Brunswick, including Acalymma gouldi Barber, Altica knabii Blatchley, Altica rosae Woods, Altica woodsi Isely, Bassareus mammifer (Newman), Chrysolina marginata (Linnaeus), Chrysomela laurentia Brown, Crepidodera violacea Melsheime...

Insect wings are great resources for studying morphological diversities in nature as well as in fossil records. Among them, variation in wing venation is one of the most characteristic features of insect species. Venation is therefore, undeniably a key factor of species-specific functional traits of the wings; however, the mechanism underlying wing vein formation among insects largely remains u...

New species of the rarely encountered megachilid genera Afroheriades Peters from South Africa, Afroheriades hyalinussp. n., and Noteriades Cockerell from Myanmar and Thailand, Noteriades jenniferaesp. n. and Noteriades spinosussp. n., are described and illustrated. The species are described to make their names available for forthcoming publications on phylogenetic studies of the family Megachil...

e One of the fundamental algorithmic problems in computer science involves selecting th -th smallest element in a collection of elements. We propose an algorithm design m k A n ethodology to solve the selection problem on meshes with multiple broadcasting. Our methodology leads to a selection algorithm that runs in O( ) time on a mesh n (log n ) 4 n 3/8 1/4 5/8 1/4 1/8 3/ (log n ) n /(log n ) a...

Mutants of Salmonella typhimurium that leaked periplasmic proteins were isolated. Four classes of mutants were identified by their increased sensitivity to dyes, detergents, or antibiotics. Conjugation studies indicated that representatives of two classes mapped in the proA-galE region of the Salmonella chromosome and two in the cysI-argE region. According to their bacteriophage sensitivity pat...

S part of a study of enzyme repression in the arginine system of Escherichia A coli, we have isolated a number of phenotypic revertants from various mutants blocked in acetylornithinase (VOGEL 1953; VOGEL and BONNER 1956), which is a biosynthetic enzyme of this system and is specified by gene argE, The mutants were derived from strain W, for which the enzymes of arginine synthesis are known and...
