Simulating a Quantum Switch With Concurrent Demands

Concurrency and Computation: Practice and Experience, Volume 37, Issue 27-28, 25 December 2025.
ABSTRACT Quantum networks rely on entanglement distribution to enable secure communication and distributed quantum computation. Most analytical models address idealized, single‐flow scenarios and overlook the impact of concurrent entanglement requests, limiting their applicability to realistic network conditions.

Stability of Queueing Systems with Impatience, Balking and Non-Persistence of Customers

Mathematics
The operation of many queueing systems is adequately described by the structured multidimensional continuous-time Markov chains. The most well-studied classes of such chains are level-independent Quasi-Birth-and-Death processes, GI/M/1 type and M/G/1 ...

From rights to runtime: Privacy engineering for agentic AI

AI Magazine, Volume 46, Issue 4, Winter 2025.
Abstract Agentic AI shifts stacks from request‐response to plan‐execute. Systems no longer just answer; they act—planning tasks, calling tools, keeping memory, and changing external state. That shift moves privacy from policy docs into the runtime.

Offline Learning for Acknowledgment Optimization in Massive LoRaWAN Networks

Internet Technology Letters, Volume 8, Issue 6, November/December 2025.
ABSTRACT LoRaWAN faces critical limitations in large‐scale deployments due to spectrum contention, duty‐cycle restrictions, and energy constraints. These challenges impact the reliability and responsiveness of bidirectional communication particularly when conventional acknowledgment mechanisms are used.

Heterogeneous Finite-Source Retrial Queues [PDF]

Journal of Mathematical Sciences, 2004
The paper considers a system with \(K\) different sources of primary calls, each consisting of a single request. When source \(i\) is free at time \(t\) (i.e., is not being served and not waiting for serving), it may generate a primary call during interval \((t,t + dt)\) with probability \(\lambda _i dt + o(dt)\).

Clinical validation of a real‐time machine learning‐based system for the detection of acute myeloid leukemia by flow cytometry

Cytometry Part B: Clinical Cytometry, Volume 108, Issue 5, Page 392-403, September 2025.
Abstract Machine‐learning (ML) models in flow cytometry have the potential to reduce error rates, increase reproducibility, and boost the efficiency of clinical labs. While numerous ML models for flow cytometry data have been proposed, few studies have described the clinical deployment of such models.

Markovian Retrial Queues with Two Way Communication

, 2012
In this paper, we first consider single server retrial queues with two way communication. Ingoing calls arrive at the server according to a Poisson process. Service times of these calls follow an exponential distribution. If the server is idle, it starts

Supporting Smart Manufacturing in the Space Industry: A Case Study

Engineering Reports, Volume 7, Issue 1, January 2025.
ABSTRACT In the era of Industry 4.0, the New Space Economy, often called Space 4.0, has taken center stage in the satellite industry. The advent of mega‐constellations, which entails mass satellite production, necessitates state‐of‐the‐art manufacturing methods.
