Alternative Vaccination Routes against Paratuberculosis Modulate Local Immune Response and Interference with Tuberculosis Diagnosis in Laboratory Animal Models

open access: yesVeterinary Sciences, 2020
Paratuberculosis (PTB) is an enteric granulomatous disease caused by Mycobacterium avium subsp. paratuberculosis (MAP) that mainly affects ruminants. Current vaccines have shown to be cost−effective control reagents, although they are restricted ...

Distinguishing between statistical and systematic errors in quantum process tomography

open access: yesNew Journal of Physics, 2019
It is generally assumed that every process in quantum physics can be described mathematically by a completely positive map. However, experimentally reconstructed processes are not necessarily completely positive due to statistical or systematic errors ...

Quantized Markov Chain Couplings that Prepare Qsamples [PDF]

open access: yesQuantum
We present a novel approach to quantizing Markov chains. The approach is based on the Markov chain coupling method, which is frequently used to prove fast mixing. Given a particular coupling, e.g., a grand coupling, we construct a completely positive and

Completely contractive maps between C*-algebras

open access: yesInternational Journal of Mathematics and Mathematical Sciences, 2002
We give a simple proof that any completely contractive map between C*-algebras is the top right hand corner of a two completely positive unital matrix operator. Some well-known results are deduced.

A novel hyperchaotic system with fast and slow attractors

open access: yesAIP Advances, 2022
A novel hyperchaotic system with only one equilibrium point is proposed by introducing an additional state feedback. The dynamic behaviors of this system are investigated by means of the Lyapunov exponent, Poincaré map, and bifurcation diagrams, i.e ...

Causality and the complete positivity of classical polarization maps [PDF]

open access: yesOptics Letters, 2011
Mueller and Jones matrices have been thoroughly studied as mathematical tools to describe the manipulation of the polarization state of classical light. In particular, the most general physical transformation on the polarization state has been represented as an ensemble of Jones matrices, as ∑iV(i)ΦV(i)(†).

Application of Remote Sensing and GIS Techniques for the Analysis of Lake Water Fluctuations: A Case Study of Ugii Lake, Mongolia [PDF]

open access: yesNature Environment and Pollution Technology, 2021
Ugii Lake is a freshwater lake located in the steppe region of Mongolia and is an important breeding and staging area for a wide variety of waterfowl. Remote sensing and geographic information system techniques were used to estimate fluctuations in the ...

Characterization of the order relation on the set of completely n-positive linear maps between C*-algebras [PDF]

open access: yesSurveys in Mathematics and its Applications, 2007
In this paper we characterize the order relation on the set of all nondegenerate completely n-positive linear maps between C*-algebras in terms of a self-dual Hilbert module induced by each completely n-positive linear map.

Entanglement-breaking superchannels [PDF]

open access: yesQuantum, 2020
In this paper we initiate the study of entanglement-breaking (EB) superchannels. These are processes that always yield separable maps when acting on one side of a bipartite completely positive (CP) map.

European Standard Clinical Practice Guideline and EXPeRT Recommendations for the Diagnosis and Management of Gastroenteropancreatic Neuroendocrine Neoplasms in Children and Adolescents

open access: yesPediatric Blood &Cancer, EarlyView.
ABSTRACT Pediatric gastroenteropancreatic neuroendocrine neoplasms (GEP‐NENs) are extremely rare and clinically heterogeneous. Management has largely been extrapolated from adult practice. This European Standard Clinical Practice Guideline (ESCP), developed by the EXPeRT network in collaboration with adult NEN experts, provides (adult) evidence ...
