Events containing an isolated prompt photon with high transverse energy, together with a balancing jet, have been observed for the first time in photoproduction at HERA. The data were taken with the ZEUS detector, in a γp centre of mass energy range 120–250 GeV. The fraction of the incoming photon energy participating in the production of the prompt photon and the jet, xγ , shows a strong peak ...

Mobile devices become smaller and more powerful with each generation distributed. Because of the tiny enclosures the interaction with such devices offers limited input capabilities. In contrast there are hardly any mobile phones purchasable that do not have a built-in camera. We developed a concept of an intuitive interaction technique using optical inertial tracking on mobile phones. The key o...

Dijet cross sections are presented using photoproduction data obtained with the ZEUS detector during 1994. These measurements represent an extension of previous results, as the higher statistics allow cross sections to be measured at higher jet transverse energy (E T ). Jets are identified in the hadronic final state using three different algorithms, and the cross sections compared to complete ...

The praying mantis genus Liturgusa Saussure, 1869 occurs only in Central and South America and represents the most diverse genus of Neotropical Liturgusini (Ehrmann 2002). The genus includes bark dwelling species, which live entirely on the trunks and branches of trees and run extremely fast. All species included within the genus Liturgusa are comprehensively revised with a distribution stretch...

We present measurements of the structure function F2 in e +p scattering at HERA in the range 3.5 GeV < Q2 < 5000 GeV. A new reconstruction method has allowed a significant improvement in the resolution of the kinematic variables and an extension of the kinematic region covered by the experiment. At Q2 < 35 GeV the range in x now spans 6.3 ·10−5 < x < 0.08 providing overlap with measurements fro...

A global event shape analysis of the multihadronic final states observed in neutral current deep inelastic scattering events with a large rapidity gap with respect to the proton direction is presented. The analysis is performed in the range 5 ≤ Q ≤ 185 GeV and 160 ≤ W ≤ 250 GeV, where Q is the virtuality of the photon andW is the virtual-photon proton centre of mass energy. Particular emphasis ...

The central aim of synthetic biology is to create and exploit biological processes that do not occur naturally. In many cases this will involve one or more steps in genetic engineering to create an organism that so far has not been found in nature. In contrast, systems biology aims to describe biological processes in their entirety, be it the complete genome of an organism, community or ecosyst...

Childhood Cancer Survivors' Workplace Experiences by Larry Ross Martinez Recent advances in the treatment of childhood cancer have resulted in more and healthier working survivors than ever before. However, the current organizational literature has not investigated concerns that this group of employees may have. This research is the first of its kind to assess the workplace experiences of child...

background: rahbdoid tumor of kidney (rtk) is a childhood rare neoplasm, previously thought as a sarcoma variant of wilms’ tumor, but now is recognized as a distinct pathologic entity. method : we report a pathologically proved case of rtk, associated with brain mass in a 4.5-month-old girl that has referred for gross hematuria. shortly after initiating chemotherapy, because of retractile vomit...
