Effects of Various Split Developmental Photophases and Constant Light During 24 Hour Period on Adult Morphology in \u3ci\u3eEuschistus Tristigmus Tristigmus\u3c/i\u3e (Hemiptera: Pentatomidae)

Rearing immatures of Euschistus tristigmus tristigmus in a range of split photophases during each 24 h period and in constant light showed that the adult dimorphic response in shoulder shape and number of midventral spots could be produced; individuals reared in photoperiods in which each scotopnase was at least 2 h in length developed into the tristigmus (short-day) form

Effects of Continuous and Split Developmental Photophases During Each 24 Hour Period on Adult Color and Pubescence in \u3ci\u3eThyanta Calceata\u3c/i\u3e (Hemiptera: Pentatomidae)

Rearing immatures of Thyanta calceata in SL: 16D, SL:4D:8L:4D, and 16L:8D photo- periods showed that the length of each photophase, rather than an accumulation of shorter photophases, during each 24 h period wa, the determining factor in producing adult di- morphism in color and pubescence

Artificial neural network prediction of weld distortion rectification using a travelling induction coil

An experimental investigation has been carried out to determine the applicability of an induction heating process with a travelling induction coil for the rectification of angular welding distortion. The results obtained from experimentation have been used to create artificial neural network models with the ability to predict the welding induced distortion and the distortion rectification achieved using a travelling induction coil. The experimental results have shown the ability to reduce the angular distortion for 8 mm and 10 mm thick DH36 steel plate and effectively eliminate the distortion on 6 mm thick plate. Results for 6 mm plate also show the existence of a critical induction coil travel speed at which maximum corrective bending occurs. Artificial neural networks have demonstrated the ability to predict the final distortion of the plate after both welding and induction heating. The models have also been used as a tool to determine the optimum speed to minimise the resulting distortion of steel plate after being subjected to both welding and induction heating processes

Eastern Range Extension of \u3ci\u3eLeptoglossus Occidentalis\u3c/i\u3e With a Key to Leptoglossus Species of America North of Mexico (Heteroptera: Coreidae)

Leptoglossus occidentalis is reported for the first time from Illinois and Michigan, and confirmed for Indiana. A key to the species of Leptoglossus occurring in America north of Mexico is presented

River Flowing from the Sunrise: An Environmental History of the Lower San Juan

The authors recount twelve millennia of history along the lower San Juan River, much of it the story of mostly unsuccessful human attempts to make a living from the river\u27s arid and fickle environment. From the Anasazi to government dam builders, from Navajo to Mormon herders and farmers, from scientific explorers to busted miners, the San Juan has attracted more attention and fueled more hopes than such a remote, unpromising, and muddy stream would seem to merit.https://digitalcommons.usu.edu/usupress_pubs/1127/thumbnail.jp

Multirelational Organization of Large-scale Social Networks in an Online World

The capacity to collect fingerprints of individuals in online media has revolutionized the way researchers explore human society. Social systems can be seen as a non-linear superposition of a multitude of complex social networks, where nodes represent individuals and links capture a variety of different social relations. Much emphasis has been put on the network topology of social interactions, however, the multi-dimensional nature of these interactions has largely been ignored in empirical studies, mostly because of lack of data. Here, for the first time, we analyze a complete, multi-relational, large social network of a society consisting of the 300,000 odd players of a massive multiplayer online game. We extract networks of six different types of one-to-one interactions between the players. Three of them carry a positive connotation (friendship, communication, trade), three a negative (enmity, armed aggression, punishment). We first analyze these types of networks as separate entities and find that negative interactions differ from positive interactions by their lower reciprocity, weaker clustering and fatter-tail degree distribution. We then proceed to explore how the inter-dependence of different network types determines the organization of the social system. In particular we study correlations and overlap between different types of links and demonstrate the tendency of individuals to play different roles in different networks. As a demonstration of the power of the approach we present the first empirical large-scale verification of the long-standing structural balance theory, by focusing on the specific multiplex network of friendship and enmity relations.Comment: 7 pages, 5 figures, accepted for publication in PNA

Exome sequencing identifies nonsegregating nonsense ATM and PALB2 variants in familial pancreatic cancer.

We sequenced 11 germline exomes from five families with familial pancreatic cancer (FPC). One proband had a germline nonsense variant in ATM with somatic loss of the variant allele. Another proband had a nonsense variant in PALB2 with somatic loss of the variant allele. Both variants were absent in a relative with FPC. These findings question the causal mechanisms of ATM and PALB2 in these families and highlight challenges in identifying the causes of familial cancer syndromes using exome sequencing
