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

The Markovian arrival process: A statistical model for daily precipitation amounts

, 2013
The Markovian arrival process (MAP) is a stochastic process that allows for modeling dependent and non-exponentially distributed observations. Due to its versatility, it has been widely applied in different contexts, from reliability to teletraffic.

Transient and stationary characteristics of a packet buffer modelled as an MAP/SM/1/b system

International Journal of Applied Mathematics and Computer Science, 2014
A packet buffer limited to a fixed number of packets (regardless of their lengths) is considered. The buffer is described as a finite FIFO queuing system fed by a Markovian Arrival Process (MAP) with service times forming a Semi-Markov (SM) process (MAP ...

Optimizing Cardiac Inpatient Flow and Resource Allocation in Low‐Resource Settings Using Queuing Theory: Insights From a Tertiary Hospital in Bangladesh

Public Health Challenges, Volume 5, Issue 2, June 2026.
This study applies queuing theory models (M/M/c/c and M/M/c/K) to optimize inpatient flow and resource allocation in the cardiology department of Sylhet MAG Osmani Medical College Hospital, Bangladesh. Using data from 6,277 patients in 2023, it identifies bottlenecks in CCU and PCCU, highlights bed shortages and overcrowding, and proposes reallocating ...

Analysis of a Semi-Open Queuing Network with a State Dependent Marked Markovian Arrival Process, Customers Retrials and Impatience

Mathematics, 2019
We consider a queuing network with single-server nodes and heterogeneous customers. The number of customers, which can obtain service simultaneously, is restricted.

Efficient Implementations of the EM-Algorithm for Transient Markovian Arrival Processes [PDF]

, 2016
There are real life applications (e.g., requests of http sessions in web browsing) with a finite number of events and correlated inter-arrival times. Terminating point processes can be used to model such behavior. Transient Markov arrival processes (TMAPs) are computationally appealing terminating point processes which are terminating versions of ...

Excitonic Theory of the Ultrafast Optical Response of 2D‐Quantum‐Confined Semiconductors at Elevated Densities

Advanced Quantum Technologies, Volume 9, Issue 6, June 2026.
In this work, an excitonic many‐body theory for the ultrafast optical response at elevated excitation densities for Wannier–Mott excitons is developed and applied to two distinct materials (GaAs quantum well and MoSe2 monolayer) as proponents of two different Coulomb‐interaction regimes.

Performance Analysis of the Sleep Mode in WiMAX 2 Networks with Multimedia Application

Journal of Applied Mathematics, 2014
We consider the sleep mode with multimedia application in WiMAX 2 networks, where the real-time traffic includes the real-time and the best-effort traffic mixed.

No safe refuge? Contrasting effects of hunting on rainforest mammal persistence and (re)colonisation

Journal of Applied Ecology, Volume 63, Issue 6, June 2026.
Our results imply that hunting not only targets areas used as refuges by wildlife, but also reduces recolonisation potential and may therefore alter source–sink dynamics. We recommend spatially targeted community‐led actions to limit hunting where wildlife still persists through the creation of no‐hunting areas to ensure the long‐term persistence of ...
