— If strange quark matter (SQM) is the true ground state of hadronic matter, then conversion of neutron stars (NS) into quark stars (QS) could release some 10 erg. We describe a scenario of burning of a NS into a hot, differentially rotating QS. Emission of released non-baryonic energy through the QS surface is discussed. The rôle of magnetobuoyancy of SQM is mentioned. The outflow of γee lasti...

Background Phase-contrast MRI (PC-MRI) can be used to assess valvular heart diseases. It can also measure pulmonarysystemic flow ratio (Qp/Qs) and help identify intracardiac shunts. However, phase offsets in PC-MRI caused by main field inhomogeneity and eddy-current introduce baseline offset errors in flow quantification and hence Qp/Qs. This error can be corrected by surface-fitting [1] or usi...

Bacterial cells sense their population density and respond accordingly by producing various signal molecules to the surrounding environments thereby trigger a plethora of gene expression. This regulatory pathway is termed quorum sensing (QS). Plenty of bacterial virulence factors are controlled by QS or QS-mediated regulatory systems and QS signal molecules (QSSMs) play crucial roles in bacteri...

Color images can be treated as two-dimensional quaternion functions. For analysis of quaternion images, a joint space-wavenumber localized quaternion S transform (QS) is presented in this study for a simultaneous determination of the local color image spectra. The QS transform uses a two-dimensional Gaussian localizing window that scales with wavenumbers. Rotation invariance, invertibility and ...

The virulence and resistance of pathogenic microorganisms are promoted by quorum-sensing (QS) mediated traits biofilms. development antimicrobial agents which can reduce the incidence microbial disrupting establishment biofilms QS, constitute a suitable strategy to emergence strains that resistant antibiotics. In this study, 3-(1,3-dithian-2-ylidene) pentane-2,4-dione ( 1 ) ethyl-2-cyano-2-(1,3...

Quorum sensing (QS) is the interaction of bacteria cell-to-cell to regulate various bacterial functions, including virulence. It has been suggested that QS interruption an anti-infective strategy combat diseases in aquaculture. This research was conducted isolate potential probiotics as degrader from fish gut and investigate its efficiency reducing Aeromonas hydrophila pathogenicity by vitro vi...

Central neuropathic pain (CNP) is considered as a complicated sensory disturbance which many multiple sclerosis (MS) patients suffer from. Although monophasic experimental autoimmune encephalomyelitis (EAE) mouse model is a gold standard model in preclinical research of MS, severe movement deficit could confound pain behaviors evaluation over the disease course. In this study, complete Freund&r...

We consider some fundamental properties of QS-algebras and show that (1) the theory of QS-algebras is logically equivalent to the theory of Abelian groups, that is, each theorem of QS-algebras is provable in the theory of Abelian groups, and conversely, each theorem of Abelian groups is provable in the theory of QS-algebras; and (2) a G-part G(X) of a QSalgebra X is a normal subgroup generated ...

Background Cardiovascular magnetic resonance (CMR) flow quantification for determining the ratio of flow between the pulmonary and systemic circulation (Qp/Qs) is used to quantify cardiac shunts. However, both the accuracy and precision of Qp/Qs can be influenced by measurement errors in flow quantification. Post-processing methods for stationary tissue background correction have been proposed ...

In this paper we first introduce the Fock-Guichardet formalism for the quantum stochastic (QS) integration, then the four fundamental processes of the dynamics are introduced in the canonical basis as the operator-valued measures, on a space-time σ-field FX, of the QS integration. Then rigorous analysis of the QS integrals is carried out, and continuity of the QS derivative D is proved. Finally...
