PYTHIA 6.4 physics and manual

The Pythia program can be used to generate high-energy-physics 'events', i.e. sets of outgoing particles produced in the interactions between two incoming particles. The objective is to provide as accurate as possible a representation of event properties in a wide range of reactions, within and beyond the Standard Model, with emphasis on those where strong interactions play a role, directly or ind

Thoracic epidural anesthesia and epidural hematoma.

This report involves a 74-year-old-male who developed a thoracic epidural hematoma with paraparesis on the second postoperative day in conjunction with thoracic epidural anesthesia established before surgery for acute abdominal aortic dissection. The finding indicates that laminectomy can be performed successfully as late as three days after diagnosis of the hematoma, with a complete restitution o

Compact difference methods applied to initial-boundary value problems for mixed systems.

An initial-boundary value problem to a system of nonlinear partial differential equations, which consists of a hyperbolic and a parabolic part, is taken into consideration, The problem is discretised by a compact finite difference method. An approximation of the numerical solution is constructed, at which the difference scheme is linearised. Nonlinear convergence is proved using the stability of t

Influence of pressurized ventilation on performance of an emergent macrophyte (Phragmites australis)

1 Pressurized ventilation, which increases gas exchange between aerial and submerged plant parts, has been found in various emergent macrophyte species. We investigated the potential for this mechanism to affect growth, morphology and biomass allocation in Phragmites australis in glasshouse experiments. 2 Inhibition of pressurized ventilation by perforation of stems above the water surface resulte

Social mating systems and extrapair fertilizations in passerine birds

Two alternative hypotheses have been proposed to explain how social and genetic mating systems are interrelated in birds. According to the first (male trade-off) hypothesis, social polygyny should increase extrapair fertilizations because when males concentrate on attracting additional social mates, they cannot effectively protect females with whom the); have already paired from being sexually ass

Bose-Einstein-condensed atoms in toroidal traps

We consider Bose-Einstein-condensed atoms confined in a toroidal trap. Under conditions of one-dimensional behavior, the density distribution of the atoms may be exponentially localized or delocalized, even for very small variations in the trapping potential along the torus. For similar reasons, small irregularities of the trap may also have a very pronounced effect on the density of the cloud. Th

Gels of hydrophobically modified hydroxyethyl cellulose cross-linked by amylose: Competition by added surfactants

Previous work has shown that amylose (AM) can cross-link hydrophobically modified polymers by inclusion complexation, whereby thermoreversible cold-setting gels are formed. This work investigates, mainly by rheology, the competition effect of seven different anionic, cationic, and nonionic surfactants when mixed at room temperature into preformed gels of AM and hydrophobically modified hydroxyethy

MAGIC-HAND: A bottle and jar opening machine for people with severe disabilities

This paper describes the development of a prototype product named MAGIC-HAND that has been developed to open bottles, jars and packages that require a twisting action. Its intended users are people with severe disabilities, who are not capable of using the current range of package opening tools. MAGIC-HAND is a kitchen accessory device that fits into standard kitchen furniture. The machine uses no

The From The Heart study: a global survey of patient understanding of cholesterol management and cardiovascular risk, and physician-patient communication

Objectives: Cardiovascular disease (CVD) is the leading cause of mortality worldwide. A high level of low-density lipoprotein cholesterol (LDL-C) is a major CVD risk factor. Guidelines recommend effective cholesterol management and set LDL-C goals, yet deficiencies exist in physician implementation of these recommendations and in patient uptake of the advice. However, little is known of patient pe

Chiral perturbation theory beyond one loop

The existing Chiral Perturbation Theory (ChPT) calculations at order p6 are reviewed. The principles of ChPT and how they are used are introduced. The main part is a review of the two- and three-flavour full two-loop calculations and their comparison with experiment. We restrict the discussion to the mesonic purely strong and semileptonic sector. The review concludes by mentioning the existing res

An expansive multiplier property for operator-valued Bergman inner functions

We show that operator-valued Bergman inner functions have the so-called expansive multiplier property generalizing a well-known result of Hedenmalm in the scalar case. This analysis leads to norm bounds for input output maps for a related class of discrete time linear systems. The proof uses properties of the biharmonic Green function.

Changes in optical properties of human whole blood in vitro due to slow heating

Optical properties of human whole blood were investigated in vitro at 633 nm using a double integrating sphere set-up, The blood flow was maintained at a constant rate through a flow cell while continuously heating the blood at 0.2-1.1 degrees C/min from approximately 25 to 55 degrees C in a heat exchanger, A small, but rather abrupt decrease in the scattering asymmetry factor (g-factor) of 1.7 +/

Global reprogramming of dendritic cells in response to a concerted action of inflammatory mediators

Maturation of dendritic cells (DC) serves a deterministic role in the link between innate and adaptive immunity, constituting a checkpoint with regard to whether responses from the lymphocyte compartment shall be raised and what class of response is needed to protect the host against invading pathogens. Since DC have not been shown to possess mechanisms such as gene recombination or somatic mutati

Neuropeptide Y potentiates noradrenaline-induced contraction through the neuropeptide Y Y1 receptor

To elucidate which neuropeptide Y receptor subtype is responsible for the neuropeptide Y-induced potentiation of the noradrenaline-evoked contraction in human omental arteries we used antisense oligodeoxynucleotide (Antisense), the new selective neuropeptide Y Y1 receptor antagonist, BIBP3226 {(R)-N2-(diphenylacetyl)-N-[(4-hydroxyphenyl) methyl]-D-arginine-amide} and the reverse transcriptase-poly

Changes in the incidence of fracture of the upper end of the humerus during a 30-year period. A study of 2125 fractures

The incidence of fracture of the upper end of the humerus by age group and sex was studied for a 32-year period from 1950 to 1982. The following numbers of humeral fractures occurred: 1950-1954, 411 fractures; 1961-1964, 552 fractures; 1971-1973, 639 fractures; and 1981-1982, 523 fractures. There was a progressive increase in the age-related incidence in older persons, especially in women. There w

Androgens and the immunocompetence handicap hypothesis: Unraveling direct and indirect pathways of immunosuppression in song sparrows

The immunocompetence handicap hypothesis proposes that testosterone (T)-dependent sexual signals are honest indicators of male health or genetic quality because only high-quality males are able to withstand the obligate effects of T-induced immunosuppression. In birds, the basic assumption that T suppresses immune function is equivocal, and the physiological mechanisms underlying T-induced immunos

Discrimination of prostate cancer from benign disease by plasma measurement of intact, free prostate-specific antigen lacking an internal cleavage site at Lys145-Lys146

BACKGROUND: The proportion of free prostate-specific antigen (PSA) is higher in the sera of patients with benign prostatic hyperplasia compared with patients with prostate cancer (PCa). We developed an immunoassay that measures intact, free PSA forms (fPSA-I), but does not detect free PSA that has been internally cleaved at Lys145-Lys146 (fPSA-N), and investigated whether this form could discrimin
