Markov‐Associated Quadratic Stochastic Families and the Susceptible‐Infected‐Recovered (SIR) Model
Mathematical Methods in the Applied Sciences, EarlyView.ABSTRACT We introduce a Markov‐associated construction for quadratic stochastic families generated by a symmetric cubic stochastic matrix and a finite‐state homogeneous Markov semigroup. The constructed family is not assumed to be a classical quadratic stochastic process of type (A)$$ (A) $$ or type (B)$$ (B) $$; rather, it is a Markov‐associated ...

Magnetic Resonance in Medicine, EarlyView.ABSTRACT Purpose The alternating unbalanced SSFP (AUSFIDE) pulse sequence, which consists of multi‐echo trains of SSFP‐FID and SSFP‐ECHO modules, enables rapid estimation of R2 and R2′, but is prone to errors from temporal drift of the main magnetic field (B0) and k‐space trajectory mismatch.

International Journal of Mechanical System Dynamics, EarlyView.ABSTRACT The design of control systems for high‐agility mechanical systems operating in extreme environments is a significant challenge in nonlinear dynamics. This paper addresses the complex dynamic control problem of a hypersonic interceptor, modeled as a multi‐input multi‐output (MIMO) mechanical system characterized by strong aerodynamic cross ...

On the Complexity of the Paper Selection Problem for the Italian Research Quality Evaluation (VQR)
Networks, EarlyView.ABSTRACT This work addresses the paper selection problem that each Italian university and department faced in the context of the research quality evaluation (VQR) of the Italian university system for the period 2020–2024. Given the set of researchers of a university and their associated papers, the problem consists of selecting a fixed number of ...

Fault‐Tolerant Mutual‐Visibility: Complexity and Solutions for Grid‐Like Networks
Networks, EarlyView.ABSTRACT Networks are often modeled using graphs, and within this setting we introduce the notion of k$$ k $$‐fault‐tolerant mutual visibility. Informally, a set of vertices X⊆V(G)$$ X\subseteq V(G) $$ in a graph G$$ G $$ is a k$$ k $$‐fault‐tolerant mutual‐visibility set (k$$ k $$‐ftmv set) if any two non‐adjacent vertices in X$$ X $$ are connected by

Quarterly Journal of the Royal Meteorological Society, EarlyView.Assimilation of AMSU‐A all‐sky observations can be increased up to fivefold if spatial observation‐error correlations are accounted for properly. New correlation estimates derived using data from ECMWF and the UK Met Office reveal that correlation length‐scales are between 75 and 150 km for AMSU‐A channels peaking in the troposphere. This is attributed
