The cosmology in the Hubble expansion era of the Horava-Witten M-theory compactified on a Calabi-Yau threefold is studied in the reduction to five-dimensions where the effects of the Calabi-Yau man-ifold are summarized by the volume modulus, and all perturbative potentials are included. Matter on the branes are treated as first order perturbations of the static vacuum solution, and all equation...

The objective of this study was to determine the role of the kallikrein-kinin system in healthy humans after intravenous administration of either Escherichia coli endotoxin or saline. We studied a total of 18 healthy nonsmoking volunteers, 23 to 38 years old, in an open-label study at the Critical Care Medicine Department, Clinical Center, National Institutes of Health (Bethesda, MD) in which s...

In the study of bi-Hamiltonian systems (both classical and quantum) one starts with a given dynamics and looks for all alternative Hamiltonian descriptions it admits. In this paper we start with two compatible Hermitian structures (the quantum analog of two compatible classical Poisson brackets) and look for all the dynamical systems which turn out to be bi-Hamiltonian with respect to them.

We give a one-parameter family of exact solutions to four-dimensional higher-spin gauge theory invariant under a deformed higher-spin extension of SO(3, 1) and parameterized by a zeroform invariant. All higher-spin gauge fields vanish, while the metric interpolates between two asymptotically AdS4 regions via a dS3-foliated domainwall and two Robertson-Walker-like H3foliated spacetimes – one in ...

Scientists are constantly searching for phytochemical compounds with anti-cancer activity. In this study, activity of plant extract NPB001-05 from Piper betle was tested on human chronic myelogenous leukemia (CML) xenograft models. NPB001-05 was active when dosed orally (500 mg/kg) once or twice a day in xenograft tumor models. NPB001-05 showed activity to T315I tumor xenograft, where imatinib ...

We introduce the neural network approach to global fits of parton distribution functions. First we review previous work on unbiased parametrizations of deep-inelastic structure functions with faithful estimation of their uncertainties, and then we summarize the current status of neural network parton distribution fits.

Given an acyclic representation α of the fundamental group of a compact oriented odddimensional manifold, which is close enough to an acyclic unitary representation, we define a refinement Tα of the Ray-Singer torsion associated to α, which can be viewed as the analytic counterpart of the refined combinatorial torsion introduced by Turaev. Tα is equal to the graded determinant of the odd signat...
