Search for direct CP violation in singly Cabibbo-suppressed D^±→K^+K^-π^± decays [PDF]

open access: yes, 2013
We report on a search for direct CP violation in the singly Cabibbo-suppressed decay D^+→K^+K^-π^+ using a data sample of 476  fb^(-1) of e^+e^- annihilation data accumulated with the BABAR detector at the SLAC PEP-II electron-positron collider, running ...

Oriented paths in n-chromatic digraphs [PDF]

open access: yes, 2010
In this thesis, we try to treat the problem of oriented paths in n-chromatic digraphs. We first treat the case of antidirected paths in 5-chromatic digraphs, where we explain El-Sahili's theorem and provide an elementary and shorter proof of it.

Measurement of Single Muons at Forward Rapidity in p+p Collisions at sqrt(s) = 200 GeV and Implications for Charm Production [PDF]

open access: yes, 2006
Muon production at forward rapidity (1.5 < |\eta| < 1.8) has been measured by the PHENIX experiment over the transverse momentum range 1 < p_T \le 3 GeV/c in sqrt(s) = 200 GeV p+p collisions at the Relativistic Heavy Ion Collider.

EXPERIMENTAL STUDY AND CALCULATIONS OF THE NEAR CRITICAL BEHAVIOR OF A SYNTHETIC FLUID IN NITROGEN INJECTION Estudio experimental y cálculos del comportamiento cercanamente crítico de un fluido sintético en inyección de nitrógeno para mantenimiento de presión

open access: yesCT&F Ciencia, Tecnología & Futuro, 2005
In recent years, the use of nitrogen has increased as gas injection to recover oil fluids near the critical point. The behavior of hydrocarbon mixture phases in the critical region shows very interesting complex phenomena when facing a recovery project ...

Evolución térmica de la Cuenca de Sabinas NE de México, a partir del estudio de inclusiones fluidas en cuerpos estratoligados [PDF]

open access: yes, 2010
En la cuenca de Sabinas la Orogenia Larámide detonó el flujo de fluidos asociado a las zonas más profundas de la cuenca, iniciándose así la acumulación de yacimientos estratoligados en el Noreste de México, los cuales se acumularon preferencialmente en ...

PVTx Properties of Liquefied Natural Gas Mixtures Using Tao-Mason Equation of State

open access: yesJOURNAL OF CHEMICAL ENGINEERING OF JAPAN, 2011
In a previous paper, we extended the Tao and Mason equation of state (TM EOS) to refrigerant fluids using speed of sound data. Herein, we employ the TM EOS to predict volumetric properties of multi-component mixtures of liquefied natural gas (LNG). The second virial coefficient, B2(T), necessary for the mixture version of the TM EOS, in the absence of ...

PVTx measurements of mixed clathrate hydrates in batch conditions under different crystallization rates: Influence on equilibrium

open access: yesJournal of Chemical Thermodynamics, 2018
Notwithstanding the numerous studies about classical temperature and pressure equilibrium of mixed gas hydrates, few provide hydrate composition and volume at local and final equilibrium under batch conditions.

Faster Eigenvector Computation via Shift-and-Invert Preconditioning

open access: yes, 2016
We give faster algorithms and improved sample complexities for estimating the top eigenvector of a matrix $\Sigma$ -- i.e. computing a unit vector $x$ such that $x^T \Sigma x \ge (1-\epsilon)\lambda_1(\Sigma)$: Offline Eigenvector Estimation: Given an ...
