Each of the world's largest retailers---Walmart, Carrefour, Tesco, and Metro---entered China after 1995. Their subsequent expansion in China may have influenced Chinese exports through two channels. First, they may have enhanced bilateral exports between the retailers' Chinese operations and destination countries also served by stores in the retailers' networks. Second, Chinese city-level expor...

Many crustaceans detect odors from distant sources using chemosensory sensilla (aesthetascs) on their antennules. The greater the flow of water through arrays of aesthetascs, the faster the access of odorant to receptors inside the aesthetascs. Stomatopods facilitate odorant access by flicking their antennules, thus increasing the relative velocity of the water reaching their aesthetascs. We us...

Protests take place for a variety of reasons. In this paper we focus on protests that have a well defined objective, that is in conflict with the objectives of the government. Hence the success or failure of a protest movement depends crucially on how the government responds. We assume that government types are private information so that governments have an interest in building a reputation to...

During this period, menarche represents the most important event in females. Age of menarche is different among populations and has been recognized as an useful marker of socio-economic status, as well as dietary and enviro...

Several methods to improve the parton-shower description of hard processes by an injection of matrix-element-based information have been presented over the years. In this article we study (re)weighting schemes for the first/hardest emission. One objective is to provide a consistent matching of the POWHEG next-to-leading order generator to the Pythia shower algorithms. Another is to correct the ...

Zusammenfassung Der Begriff „Biosensoren“ ist ein Sammelwort für tragbare Anwendungen, die biologische Funktionen erfassen. Die gängigsten Biosensoren sind Akzelerometer mit zunehmenden Anwendungsbereichen als Multi-Sensor-Anwendungen oder elektrodermale Sensoren. nehmen eine Bewegung bzw. Beschleunigung von Objekten im Raum wahr und Zuge der technischen Entwicklungen letzten Jahre werden sie h...

hirschsprung's disease, also known as congenital aganglionic megacolon, is a congenital disorder which develops due to an absence of neural ganglia in a segment of large bowel. most commonly, the rectum or rectosigmoid, and rarely other areas or the entire colon are involved. in this disease, all three neural plexi, i.e., the myenteric (auerbach's) plexus, the superficial submucosal (...

Hirschsprung's disease (HD) is a common congenital disease of colorectum. Although it was described more than one century ago, the effective treatment was established only half a century later. The initially treatment consisted of preoperative diverting colostomy, followed by definite pull-through and closure of colostomy on later date. A variety of procedures like Swenson, Duhamel, Rehbein and...
