Transverse momentum as a measure of color topologies

Several distinct color flow topologies are possible in multiparton configurations. A method is proposed to find the correct topology, based on a minimization of the total transverse momentum of produced particles. This method is studied for three-jet [Formula presented] and four-jet [Formula presented] events. It is shown how the basic picture is smeared, especially by parton-shower activity. The

Angelic humans, glorious flesh : Jerome's reception of Origen's teachings on the resurrection body

One of the most important theological questions in the first Origenist controversy was that of the resurrection of the dead. Jerome accused both Origen and contemporary “Origenists” of speaking only of the resurrection of the body, and not of the flesh, and he claimed that an idea of resurrection without the flesh could not guarantee the identity between the body living on earth and the resurrecte

MEK1/2 inhibitor U0126, but not nimodipine, reduces upregulation of cerebrovascular contractile receptors after subarachnoid haemorrhage in rats

Vascular pathophysiological changes after haemorrhagic stroke, such as phenotypic modulation of the cerebral arteries and cerebral vasospasms, are associated with delayed cerebral ischemia (DCI) and poor outcome. The only currently approved drug treatment shown to reduce the risk of DCI and improve neurologic outcome after aneurysmal subarachnoid haemorrhage (SAH) is nimodipine, a dihydropyridine

Cyclohexane-Based Phosphinite Iridium Pincer Complexes : Synthesis, Characterization, Carbene Formation, and Catalytic Activity in Dehydrogenation Reactions

Metalation of two cyclohexane-based phosphinite pincer ligands, cis-POCyPO (4) and trans-POCyPO (5) (POCyPO = {1,3-bis-[(di-tert-butylphosphinito]cyclohexane}−), is reported. In line with previously published results (Dalton Trans. 2009, 8626, DOI: 10.1039/B910798C), ligand 4 undergoes aromatization to give benzene-based complex (POCOP)IrHCl (3) at high temperatures in the presence of [Ir(COD)Cl]2

Cyclometalation reactions on rhodium(I). Evidence for a chelate effect and competing C-H and C-O oxidative additions

The ligand Ph2PC6H4(CH2N(Me)CO(Et)) reacts with (bis(diphenylphosphino)butane) (2,5-norbornadiene)rhodium tetrafluoroborate (2a) and (bis(diphenylphosphino)ethane)(2,5-norbornadiene) rhodium tetrafluoroborate (2b) at room temperature in the presence of hydrogen to displace the norbornadiene and give the chelate complexes 3a,b, in which the phosphorus and the oxygen atoms are coordinated to give an

Mao’s Homeworld(s) : A Comment on the Use of Propaganda Posters in Post-War China

Within cognitive science, narratives are regarded as crucial and fundamental cognitive instruments or tools. As Roger Schank suggests, the identity of (sub-)cultures is to a considerable extent based upon the sharing of narrative structures (Schank. 1995. Tell me a story: Narrative and intelligence. Evanston, IL: Northwestern University Press.). According to Schank, culturally shared stories, as d

Quality of life and tax legislation as an instrument for cultural policy goals, taking private patronage as an example

Historically, private initiative has always been of great significance for the arts. In most Europe-an countries the government took over from the private initiative after World War II. However, private initiative never completely disappeared, this is also true in the second half of the 20th century in which government subsidies were the dominant factor in the funding of the arts and cultural heri

Parvovirus B19 infection in pregnancy and subsequent morbidity and mortality in offspring

BACKGROUND: Because parvovirus B19 infection in pregnancy has been associated with infant morbidity and mortality in case reports and after intrauterine transfusion, we tested the population-based association using serum and hospital data of high quality.METHODS: We established a cohort of 113 228 children born to women tested for parvovirus B19 infection during pregnancy in a major diagnostic lab

The benefit of molecular characterization during a measles upsurge in Denmark

Molecular characterization of measles virus was part of the epidemiological investigation of 27 measles cases reported in Denmark in 2006. RT-PCR detected measles virus RNA from various types of clinical specimens in 24 cases. Virus genotypes were determined by sequencing the nucleocapsid (N) gene. Four different genotypes, B3, D4, D5 and D9 were identified including two variants of the D4 genotyp

Violations of Dashen's theorem

The electromagnetic contribution to the K+-K0 mass difference is calculated in the 1 Nc approach including the SU(3) breaking contributions due to a non-zero strange quark mass. The short-distance contribution can be unambiguously determined in terms of the known parameters of the next-to-leading order chiral Lagrangian. The long distance part is estimated using the 1 Nc approach by Bardeen et al.

Age, vulnerability and disability

This chapter is one of two theoretical pieces in this international collection. The aim is to challenge the traditional perception of who is a vulnerable person by discussing the concept from the vulnerability theory standpoint that basically accepts vulnerability as a universal state of being. It discusses the risk that the distribution of public services ends up being based on age absent conside

Chlorinated persistent organic pollutants and type 2 diabetes - A population-based study with pre- and post- diagnostic plasma samples

Background: Persistent organic pollutants (POPs) have been associated with type 2 diabetes (T2D), but causality is uncertain. Objective: Within longitudinal population-based data from northern Sweden, we assessed how POPs associated with T2D prospectively and cross-sectionally, and further investigated factors related to individual changes in POP concentrations. Methods: For 129 case-controls pair
