Let G be a connected reductive algebraic group over an algebraically closed field k. Let Z be the algebraic variety consisting of all triples (P, P , UP ′gUP ) where P, P ′ run through some fixed conjugacy classes of parabolics in G and g is an element of G that conjugates P to a parabolic in a fixed ”good” relative position y with P ′ (here UP , UP ′ are the unipotent radicals of P, P ). The v...

The rst measurement of the quasi-free p+n!p+n+ reaction cross section has been made at the CELSIUS storage ring using a deuterium internal cluster jet target. The energy dependence of the cross section is extracted using a xed incident proton energy of T p = 1350 MeV and exploiting the Fermi momentum of the struck neutron. The data cover a range of centre-of-mass excess energies from 16 MeV to ...

In this appendix, we first describe the mathematical derivation of the marginal likelihood of model Mh: P (G|Mh) (Section 2). Then we show four equivalent formulas for solving P (G|Mh) (Section 3). After that, we show how to obtain the marginal likelihood of model Ml from the solution to the marginal likelihood of model Mh (Section 4). Finally, we show that the overall computational complexity ...

Background: The increase in the prevalence of cesarean section (C-section) in recent decades has become a public health problem worldwide. Studies of cesarean section in order to identify the causes and form policies and interventions to reduce the incidence of this health problem are necessary. This study was conducted with the aim to investigate the causes of C-sections performed at Niknafs a...

PHENIX measures leptons at mid and forward rapidities and extracts leptons resulting from semi-leptonic decays of heavy quarks. We present PHENIX results related to heavy quark production, specifically the invariant cross section of the non-photonic single electrons produced at midrapidity in p+p and d+Au collisions at √ sNN = 200 GeV . The measured cross section for p+p collisions is compared ...

Recently a species in the genus Talaromyces, a uniseriate species of Aspergillus section Nigri and an isolate each of two widespread species, Penicillium rubens and P. commune, were reported to produce ochratoxin A. This claim was based on insufficient biological and chemical data. We propose a list of criteria that need to be met before an unexpected mycotoxin producer is reported. There have ...
