microscopy as “field based test” was compared with is900 blood pcr for the diagnosis and estimationof prevalence of mycobacterium avium subspecies paratuberculosis (map) in domestic livestock withclinical johne’s disease (jd). of 252 animals screened, 39.3 and 13.1% were positive by faecal microscopyand blood pcr, respectively. proportional agreement between “microscopy” and blood pcr was subst...
INTRODUCTION The relationships between systemic hemodynamics and renal blood flow and renal microcirculation are poorly known in sepsis. Norepinephrine (NE) infusion may add another level of complexity. METHODS Ventilated and anesthetized rats were submitted to various mean arterial pressure (MAP) steps by blood removal, in presence and absence of sepsis and/or NE. Renal blood flow (RBF) and ...
This paper presents a new air traffic complexity metric based on linear dynamical systems, of which the goal is to quantify intrinsic set aircraft trajectories. Previous works have demonstrated that structure and organization are essential factors in perception an situation. Usually, they were not able explicitly address trajectory pattern organization. The metric, by identifying properties tra...
Quantum process tomography is a procedure by which an unknown quantum operation can be fully experimentally characterized. We reinterpret Choi’s proof of the fact that any completely positive linear map has a Kraus representation [Lin. Alg. and App., 10, 1975] as a method for quantum process tomography. Furthermore, the analysis for obtaining the Kraus operators are particularly simple in this ...
We prove that the stationarity and the ergodicity of a quantum source {ρ[1,m]}m=1 are preserved by any trace-preserving completely positive linear map of the tensor product form E⊗m, where a copy of E acts locally on each spin lattice site. We also establish ergodicity criteria for so called classically-correlated quantum sources.
