Fitting second-order acyclic Marked Markovian Arrival Processes
2013 43rd Annual IEEE/IFIP International Conference on Dependable Systems and Networks (DSN), 2013 Markovian Arrival Processes (MAPs) are a tractable class of point-processes useful to model correlated time series, such as those commonly found in network traces and system logs used in performance analysis and reliability evaluation. Marked MAPs (MMAPs) generalize MAPs by further allowing the modeling of multi-class traces, possibly with cross ...

Preference‐Based Representations for Collective Agency
Topics in Cognitive Science, EarlyView.Abstract Computational accounts of learning and decision‐making in cognitive systems, and models thereof, such as reinforcement learning, typically assume that the behavior of individual agents is determined by an externally designated reward signal such that the agent's goal is the maximization of its expected accumulated reward under the state ...

An innovative modelling proposal for the blood supply chain
Vox Sanguinis, EarlyView.Abstract Whole‐blood donation and apheresis are the only ways to obtain blood components for human use. Tools are being developed to improve the efficiency of blood donation systems by reducing waste, increasing donations and preventing shortages.

The Journal of Physiology, EarlyView.Abstract figure legend Catecholaminergic polymorphic ventricular tachycardia (CPVT) variants in N terminal (NTD) and central domain (CD) but not pore domain induce a pathological RyR2 conformational shift upon protein kinase A (PKA) phosphorylation, similar to that seen in heart failure (HF), calcium/calmodulin‐dependent protein kinase II (CaMKII ...

Stationary characteristics of unreliable queueing system with a batch Markovian arrival process
Informatika, 2019 Unreliable queuing systems are of considerable interest both in mathematical terms and for applications. Systems with stationary Poisson flows of customers and breakdowns and exponentially distributed service and repair times are mainly considered.

Mathematical Finance, Volume 36, Issue 3, Page 595-619, July 2026.ABSTRACT We introduce a dynamic and stochastic interbank model with an endogenous notion of distress contagion, arising from rational worries about future defaults and ensuing losses. This entails a mark‐to‐market valuation adjustment for interbank claims, leading to a forward‐backward approach to the equilibrium dynamics whereby future default ...

The Canadian Journal of Chemical Engineering, Volume 104, Issue 6, Page 3038-3051, June 2026.Abstract Identification of firefighting strategies (i.e., which endangered units to suppress or cool first) in chemical and process plants falls under the domain of multi‐objective decision‐making (MODM), where not only the safety and integrity of the affected process plant but also the safety of on‐site and off‐site vulnerable targets matter.

BiT‐MoFE: Unified illumination correction in capsule endoscopy
Journal of Intelligent Medicine, Volume 3, Issue 2, Page 125-139, June 2026.Abstract As a prevalent non‐invasive screening technique, Wireless Capsule Endoscopy is often hindered by poor image quality, including under‐/overexposure and low light condition. While illumination correction based on diffusion modeling or frequency‐domain decomposition has shown effectiveness, existing methods often (1) underexploit structural ...

On MAP Estimates and Source Conditions for Drift Identification in SDEs
Proceedings in Applied Mathematics and Mechanics, Volume 26, Issue 2, June 2026.ABSTRACT We consider the inverse problem of identifying the drift in an stochastic differential equation (SDE) from n$n$ observations of its solution at M+1$M+1$ distinct time points. We derive a corresponding maximum a posteriori (MAP) estimate, we prove differentiability properties as well as a so‐called tangential cone condition for the forward ...

Functional dynamics of water in New Delhi metallo‐β‐lactamase catalysis
Protein Science, Volume 35, Issue 6, June 2026.Abstract Water plays a critical role in the hydrolysis of antibiotics by New Delhi metallo‐β‐lactamases (NDMs). The reaction proceeds through a nucleophilic attack on the β‐lactam ring, followed by cleavage of the C–N bond and formation of an anionic nitrogen intermediate. This intermediate is then protonated by a water molecule diffusing from the bulk
