Stochastic Modelling of Daily Precipitation in Semi‐Arid Regions Using Markov Chains and Parametric Distributions

open access: yesInternational Journal of Climatology, EarlyView.
This study applies stochastic rainfall models combining Markov Chains with gamma and mixed exponential distributions to a semi‐arid climate in Northeast Brazil. Model structures were evaluated using Bayesian Information Criterion (BIC), with maximum likelihood (MLM) for parameter estimation and cumulative distribution functions (CDFs) for validation ...

Optimal control of infinite-dimensional piecewise deterministic Markov processes and application to the control of neuronal dynamics via Optogenetics

open access: yesNetworks and Heterogeneous Media, 2017
In this paper we define an infinite-dimensional controlled piecewise deterministic Markov process (PDMP) and we study an optimal control problem with finite time horizon and unbounded cost.

Last‐minute coordination: Adapting to demand to support last‐mile operations

open access: yesJournal of Operations Management, Volume 71, Issue 2, Page 176-194, March 2025.
Abstract In the highly competitive e‐commerce industry, customer‐facing warehouses are crucial as the “order penetration points” for e‐commerce last‐mile operations. This research examines how warehouses use last‐minute coordination, an unstructured mechanism, to ensure sufficient inventory at the order penetration points. Previous research has focused

Intuition–Driven Prospection and Uncertainty Misalignment: Sources of Entrepreneurial Agency Problems in Ventures

open access: yesStrategic Change, EarlyView.
ABSTRACT Start‐up CEOs are usually more aligned with the interests of the venture board compared to CEOs in legacy firms, and therefore it is usual to conclude that the traditional agency problem is lower in ventures. In this article, it is argued that this is only half of the story, and that the agency problem is reversed in early ventures such that ...

Efficacy of Lebrikizumab in Patients With Severe Atopic Dermatitis Who Would be Eligible for Treatment Based on the South Korean Reimbursement Criteria

open access: yesJEADV Clinical Practice, EarlyView.
ABSTRACT Background Lebrikizumab is approved to treat patients with moderate‐to‐severe atopic dermatitis (AD). Objectives This study evaluated the 16‐week efficacy outcomes of lebrikizumab in adults and adolescents with severe AD in ADvocate trials who would be eligible for treatment based on South Korean reimbursement‐like criteria. Methods This was a

Ship Scheduling Algorithm Based on Markov-Modulated Fluid Priority Queues

open access: yesAlgorithms
As a key node in port logistics systems, ship anchorage is often faced with congestion caused by ship flow fluctuations, multi-priority scheduling imbalances and the poor adaptability of scheduling models to complex environments.

Desertification Risk: Bibliometric Analysis and Future Research Directions

open access: yesLand Degradation &Development, EarlyView.
ABSTRACT Desertification, driven by climatic and anthropogenic factors, is one of the most pressing global environmental challenges, causing significant economic, ecological, and social consequences. A bibliometric analysis was performed to identify research trends and gaps in the desertification risk topic.

Optimal Inspection and Maintenance Policy: Integrating a Continuous-Time Markov Chain into a Homing Problem

open access: yesMachines
The state of a machine is modeled as a controlled continuous-time Markov chain. Moreover, the machine is being serviced at random times. The aim is to maximize the time until the machine must be repaired, while taking the maintenance costs into account ...
