Microrobotic Catheterization of the Ophthalmic Artery for Targeted Treatment of Retinoblastoma

Advanced Intelligent Systems, EarlyView.
A microrobotic platform is presented that allows teleoperated and autonomous navigation of flow‐driven magnetic microcatheters, MagFlow, into the ophthalmic artery for superselective intra‐arterial infusion of chemotherapy to treat retinoblastoma. Extensive benchtop validations with patient‐derived biomimetic phantoms under optical and fluoroscopic ...

Queueing network model of a call center with customer retrials and impatient customers [PDF]

Известия Саратовского университета. Новая серия: Математика. Механика. Информатика
The subject of mathematical study and modelling in this paper is an inbound call center that receives calls initiated by customers. A closed exponential queueing network with customer retrials and impatient customers is used as a stochastic model of call

Using non‐linear slide decks to administer individualized problem‐based learning assessments within pharmacology education

British Journal of Clinical Pharmacology, EarlyView.
Aim Problem‐based learning (PBL) is an established approach in medical, nursing, pharmacy and veterinary medicine education. This study describes the implementation and aims to evaluate the use of non‐linear slide decks as a method to deliver PBL as individualized student assessments within pharmacology education. This approach, originally developed in

Framework for Analysis of Queueing Systems with Correlated Arrival Processes and Simultaneous Service of a Restricted Number of Customers in Scenarios with an Infinite Buffer and Retrials

Algorithms
In this paper, we create a framework for the uniform algorithmic analysis of queueing systems with the Markov arrival process and the simultaneous service of a restricted number of customers, described by a multidimensional Markov chain.

Traffic Flow Data Collection Methods During Wildfire Evacuation

Fire and Materials, EarlyView.
ABSTRACT With climate change and urbanisation increasing wildfire risk in the wildland–urban interface (WUI), enhancing community evacuation preparedness is crucial. This study evaluates different data collection methods for measuring traffic flows during a community wildfire evacuation drill in Roxborough Park, Colorado, in June 2024.

Performance analysis of a cellular mobile network with retrials and guard channels using waiting and first passage time measures

, 2009
Most studies of modern cellular mobile networks concern performance measures directly computable from the stationary state probabilities such as the blocking probability and the mean traffic rates of the various kinds of calls. In this paper, we consider

Overshooting of Hypoplastic Models With Intergranular Strain: Manifestation, Implications and Remedy

International Journal for Numerical and Analytical Methods in Geomechanics, EarlyView.
ABSTRACT Intergranular strain extensions of hypoplasticity (IGS, ISA, GIS) are widely used to model small‐strain and cyclic soil behaviour. However, recent studies and our own simulations reveal that these models can exhibit stress overshooting not only under repeated small loading cycles but also during monotonic loading.

Relational structure of illegal wildlife hunting in China: A nationwide hunter–prey network analysis

People and Nature, EarlyView.
Abstract Illegal wildlife hunting continues to pose a major biodiversity threat in China, yet there remains no systemic relational understanding of the way in which perpetrators are linked to key taxa. To address this, here we provide a novel framework for understanding and addressing the systemic roots of wildlife crime.
