A compatibility criterion for optimal control and information aggregation in hierarchical network systems

open access: yesAsian Journal of Control, EarlyView.
Abstract Large swarms often adopt a hierarchical network structure that incorporates information aggregation. Although this approach offers significant advantages in terms of communication efficiency and computational complexity, it can also lead to degradation due to information constraints.

Risk‐aware safe reinforcement learning for control of stochastic linear systems

open access: yesAsian Journal of Control, EarlyView.
Abstract This paper presents a risk‐aware safe reinforcement learning (RL) control design for stochastic discrete‐time linear systems. Rather than using a safety certifier to myopically intervene with the RL controller, a risk‐informed safe controller is also learned besides the RL controller, and the RL and safe controllers are combined together ...

Generalized Kantorovich type Szász-Mirakjan operators based on q-integers

open access: yesFilomat
In this paper, we introduce a new type Kantorovich variant of Sz?sz-Mirakjan operators based on q-integers. We study convergence properties by using Korovkin?s theorem and estimate the rate of convergence by using modulus of continuity. We examine local and weighted approximation properties in terms of modulus of continuity. We obtain a direct estimate

A Guide to Bayesian Optimization in Bioprocess Engineering

open access: yesBiotechnology and Bioengineering, EarlyView.
ABSTRACT Bayesian optimization has become widely popular across various experimental sciences due to its favorable attributes: it can handle noisy data, perform well with relatively small data sets, and provide adaptive suggestions for sequential experimentation.

Necessary and sufficient conditions for oscillation of the solutions of even order differential equations

open access: yesJournal of Numerical Analysis and Approximation Theory, 2012
In this paper, we establish several necessary and sufficient conditions for oscillation of the solutions of the following even order differential equation\[x^{(n)}(t) + q(t)x^\gamma (t) = 0, \quad \mbox{$n$ is even},\]where \( q(t) \in C([t_0 ,\infty ),{\

Hybrid mean value involving some two-term exponential sums and fourth Gauss sums

open access: yesElectronic Research Archive
Let $ q\ge3 $ be a positive integer. For any integers $ m $, $ n $, $ k $, $ h $, the two-term exponential sums $ C(m, n, k, h; q) $ is defined as $ C(m, n, k, h;q) = \sum\limits_{a = 1}^{q}e\left(\frac{ma^k+na^h}{q}\right) $, where $ k > h\ge 2 $.

Sustainability‐Linked Trade Credit and Inventory Strategies in Supply Chains: An Integrated Modeling Approach

open access: yesBusiness Strategy and the Environment, EarlyView.
ABSTRACT Despite the growing research on sustainability, exactly how sustainability and trade credits are linked in the supply chain (SC) is still unclear. Therefore, this study aims to bridge this gap by examining how both supplier and retailer sustainability‐linked strategies and investment decisions influence trade credit terms, inventory decisions,

Fractal Anatomy of Human Organs: A Narrative Review of Structure, Function, and Clinical Perspectives

open access: yesClinical Anatomy, EarlyView.
ABSTRACT Fractal geometry describes complex, self‐similar patterns that repeat across spatial scales and is increasingly recognized as relevant in anatomical research. Indeed, the fractal organization is consistently observed in respiratory, cardiovascular, gastrointestinal, nervous, renal, hepatic, and dermatological systems.
