Isolated electrons and muons in events with missing transverse momentum at HERA

A search for events with a high-energy isolated electron or muon and missing transverse momentum has been performed at the electron-proton collider HERA using an integrated luminosity of 13.6 pb(-1) in e(-) p scattering and 104.7 pb(-1) in e(+) p scattering. Within the Standard Model such events are expected to be mainly due to W boson production with subsequent leptonic decay. In e(-) p interacti

ZOOPLANKTON FEEDING ECOLOGY - GRAZING DURING ENCLOSURE STUDIES OF PHYTOPLANKTON BLOOMS FROM THE WEST-COAST OF SWEDEN

The effects of grazing on natural phytoplankton populations was examined during enclosure studies on the effects of nutrients, zooplankton, and ctenophores on phytoplankton bloom dynamics on the west coast of Sweden in May, 1990. Grazers included the copepods Acartia clausi Giesbrecht, Centropages hamatus Lilljeborg, and Oithona similis Claus, and the marine cladoceran Podon polyphemoides Leuckart

Influence of gamma radiation on potato starch gelatinization studied by differential scanning calorimetry

The paper presents a study of the influence of the conditions applied during differential scanning calorimetry (DSC) Measurements (concentration and heating rate) oil the possible detection of the differences between gelatinization occuring in both non-irradiated and irradiated potato starch with a dose of 20kGy. Differences in gelatinization of irradiated and non-irradiated potato starch during D

Pollen donor identity affects timing of stigma receptivity in Collinsia heterophylla (Plantaginaceae): a sexual conflict during pollen competition?

Theory predicts that, during pollen competition, selection may favor a pollen trait that increases donor competitive ability at the expense of the female reproductive function. One such pollen trait could be manipulation of the onset of stigma receptivity. We evaluated the potential occurrence of this kind of sexual conflict by testing female control of the timing of stigma receptivity in the self

Area-efficient configurable high-throughput signal detector supporting multiple MIMO modes

Abstract in UndeterminedThis paper presents a low-complexity, highthroughput,and configurable multiple-input multiple-output(MIMO) signal detector design solution targeting the emergingLong-Term-Evolution-Advanced (LTE-A) downlink. The detectorsupports signal detection of multiple MIMO modes, whichare spatial-multiplexing (SM), spatial-diversity (SD), and spacedivision-multiple-access (SDMA). Area

Platelet transcriptional profile and protein expression in patients with systemic lupus erythematosus: up-regulation of the type I interferon system is strongly associated with vascular disease.

Patients with systemic lupus erythematosus (SLE) have a markedly increased risk to develop cardiovascular disease, and traditional cardiovascular risk factors fail to account for this increased risk. We used microarray to probe the platelet transcriptome in individuals with SLE and healthy controls, and the gene and protein expression of a subset of differentially expressed genes was further inves

Visions and open challenges for a knowledge-based culturomics

The concept of culturomics was born out of the availability of massive amounts of textual data and the interest to make sense of cultural and language phenomena over time. Thus far however, culturomics has only made use of, and shown the great potential of, statistical methods. In this paper, we present a vision for a knowledge-based culturomics that complements traditional culturomics. We discuss

Efficacy of mobile telephone contact for follow-up in injecting heroin users.

Background: Prospective follow-up of heroin users is known to be difficult due to their unstable lifestyle, and high follow-up rates have usually demanded major tracking efforts. In Sweden, mobile telephones are commonly used by heavy drug users for drug trading. Objectives: This methodology study aims to examine the efficacy of mobile telephone contact for prospective follow-up interviews with in

Deglutition after near-fatal choking episode: radiologic evaluation

Acute airway obstruction during oral intake is a relatively common event that may be fetal if not relieved immediately. Deglutition was studied in 75 individuals who had experienced a near-fatal choking episode (NFCE) or sudden inability to breathe during food intake that was promptly relieved by means of a Heimlich maneuver, suctioning, or intubation. Videofluoroscopy supplemented by static imagi

Effects of vaginally delivered estrogens

INTRODUCTION: Atrophic condition in the vagina and lower parts of the urethral tract are common in elderly women. From population based surveys it has been estimated that 40% or more of women over 60 complain of insufficient control of micturation. In addition, lower urinary tract infections are common in this age group and recurrent cystitis is a scourge for many women (1, 2). Vaginal problems su

Some known elementwise methods of PAA calibration are considered, without use of phase meas-urement apparatus. Features of these methods are described for the case of multi-channel phased array antennas (several hundreds or thousands of channels). Calibration algorithm is suggested for this case, it consists of antenna channels grouping, in-group channel calibration and, finally, mutual calibratio
