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

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

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

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

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

This chapter discusses different coals compared with respect to the extent of sulfur removal and jarosite formation when processed with A. brierleyi. All coals are of low-sulfur type with a sulfur content ranging from 0.6 % through 1.8 %. The efficiency of the microbial processing of coal depends on three factors––namely, the rate of sulfur removal, the extent of sulfur removal, and the formation

Syndactyly is usually corrected surgically during the first years of life. The trilobed flap, a surgical method that does not require skin grafting, was developed in the 1990s and the short-term results were comparable with previously reported techniques. Here we report on long-term outcomes, focusing on how children perceive their hand function and quality of life when they grow up. A total of 19

Circadian rhythms are ubiquitous in biological systems and regulate metabolic processes throughout the body. Misalliance of these circadian rhythms and the systems they regulate has a profound impact on hormone levels and increases risk of developing metabolic diseases. Melatonin, a hormone secreted by the pineal gland, is one of the major signaling molecules used by the master circadian oscillato

For a long time, reactive oxygen species (ROS) produced by the phagocyte NADPH oxidase (NOX2) complex have been considered harmful mediators of inflammation owing to their highly reactive nature. However, there are an increasing number of findings suggesting that ROS produced by the NOX2 complex are anti-inflammatory and prevent autoimmune responses, thus challenging existing dogma. ROS might not

Unilateral injection of the catecholamine neurotoxin 6-hydroxydopamine into the axons or terminals of the nigrostriatal pathway is commonly used to model Parkinson's disease in experimental animals. Although the terminal lesion paradigm is considered to induce a more progressive lesion when compared to the axonal lesion, few studies have directly compared the early time-course for lesion developme

1. During operative aorto-femoral vascular reconstructions on sixteen patients, the sympathetic chain was stimulated electrically between the L2 and L4 ganglia while blood flow was monitored by laser doppler flowmeters from the skin on the sole of the foot and the ankle and by an electromagnetic flowmeter from the deep femoral artery. Epidural anaesthesia to at least the T6 level was used which ex

ydrophobically modified polymers (HM-P) typically behave as thickeners in a wide range of systems. The thickening effect in an aqueous solution of this kind of polymer depends on intermolecular hydrophobic associations and also on chain entanglements if the polymer concentration is significantly above the overlap concentration. In the present investigation a rather short end-capped polymer has bee

Birdsong is one of the main models in sexual selection studies. Most investigations focused on oscines in which male song and female preference learning occur. Yet, some non-oscines are well suited for such studies as well. In Columbidae song learning does not occur. However, like in oscines, song is involved in inter- and intra-sexual interactions. Surprisingly, experimental evidence of female so

This study forms part of a larger European programme investigating the transition from home care to long-term care (LTC) facility in people with dementia (PwD) at the margins of LTC. The aim of this study was to explore the factors associated with depressive symptomatology in PwD in different settings.

The present study was designed to evaluate yoga's impact on blood pressure (BP) and quality of life (QOL) and on stress, depression and anxiety in patients with hypertension in a primary care setting. We conducted a multi-centre randomized controlled trial with follow-up after 12-week intervention completion. Adult primary care patients diagnosed with hypertension were randomly allocated to yoga o
