Contraction analysis of time-varying DAE systems via auxiliary ODE systems [PDF]
This paper studies the contraction property of time-varying differential-algebraic equation (DAE) systems by embedding them to higher-dimension ordinary differential equation (ODE) systems. The first result pertains to the equivalence of the contraction of a DAE system and the uniform global exponential stability (UGES) of its variational DAE system ...

First integrals of ordinary linear differential systems [PDF]
The spectral method for building first integrals of ordinary linear differential systems is elaborated. Using this method, we obtain bases of first integrals for linear differential systems with constant coefficients, for linear nonautonomous differential systems integrable in closed form (algebraic reducible systems, triangular systems, the Lappo ...

UNVEILING THE SECRET CHEMISTRY OF STREET ART BY A MULTI‐TECHNIQUE APPROACH
In recent years, graffiti and street art have gained recognition as legitimate art forms, deserving of the same care and attention as traditional art. As a result, conservators and restorers are now working to develop standardized guidelines for the cleaning, conservation, and restoration of these vibrant works.

Adverse drug reactions (ADRs) are a common cause of morbidity and mortality in hospitalized patients. Identification of ADRs in clinical practice, surveillance and research is essential to prevent further harm. The aim of this study was to assess the likelihood of drugs contributing to clinically important inpatient adverse events, in order to provide ...

Among patients with new‐onset or worsening heart failure (HF) undergoing optimization of HF medical therapy, dose up‐titration of angiotensin‐converting enzyme inhibitor/angiotensin receptor blocker (ACEi/ARB) therapy was associated with lower likelihood of left atrial adverse remodelling (LAAR).

Complex Systems + Systems Engineering = Complex Systems Engineeri [PDF]
One may define a complex system as a system in which phenomena emerge as a consequence of multiscale interaction among the system's components and their environments. The field of Complex Systems is the study of such systems--usually naturally occurring, either bio-logical or social.

Aims To assess adherence to guideline recommendations among a large network of Italian cardiology sites in the management of acute and chronic heart failure (HF) and to evaluate if an ad‐hoc educational intervention can improve their performance on several pharmacological and non‐pharmacological indicators.

Systems of quotients of Lie triple systems [PDF]
In this paper, we introduce the notion of system of quotients of Lie triple systems and investigate some properties which can be lifted from a Lie triple system to its systems of quotients. We relate the notion of Lie triple system of Martindale-like quotients with respect to a filter of ideals and the notion of system of quotients, and prove that the ...

Abstract A 31‐year‐old male presented with unexplainable symptoms of heart failure including recurrent fatigue and orthopnoea after total arch replacement for type A aortic dissection 2 months ago. Computed tomography angiography detected a severe intra‐luminal stenosis, and we successfully implanted a balloon‐expandable stent to dilate the stenosis ...
