Controllability and Observability Conditions for Impulsive DAEs on Time Scales
Asian Journal of Control, EarlyView.ABSTRACT This paper establishes criteria for controllability and observability in a class of linear time‐invariant impulsive differential‐algebraic equations (DAEs) defined on a time scale. Controllability is defined as the ability to transfer the system state from any initial condition to any desired state within a finite time interval using an ...

Real‐time biosensing of Parkinson's disease biomarkers via NIR‐activated upconversion nanoparticles
BMEMat, EarlyView.Schematic illustration of the luminescence resonance energy transfer‐driven core‐shell‐shell UCNPs (cssUCNPs@Fluo4) nanoprobe for simultaneous monitoring of Ca²⁺‐temperature dynamics in Parkinson's disease models. Abstract Parkinson's disease (PD) is a progressive neurodegenerative disorder with incompletely understood pathophysiology, necessitating ...

On the Diophantine equation $\sum _{j=1}^kjF_j^p=F_n^q$
, 2018 summary:Let $F_n$ denote the $n^{th}$ term of the Fibonacci sequence. In this paper, we investigate the Diophantine equation $F_1^p+2F_2^p+\cdots +kF_{k}^p=F_{n}^q$ in the positive integers $k$ and $n$, where $p$ and $q$ are given positive integers.

Business Strategy and the Environment, EarlyView.ABSTRACT This study demonstrates how a profitable, lean, and environmentally responsible e‐waste reverse logistics system can be designed using integrated Operations Research (OR) techniques. Addressing the growing urgency of responsible consumption (UN SDG 12) and the projected rise of the e‐waste sector to USD 137.60 billion by 2029, the research ...

The unit group of some fields of the form $\mathbb {Q}(\sqrt {2}, \sqrt {p}, \sqrt {q}, \sqrt {-l})$
summary:Let $p$ and $q$ be two different prime integers such that $p\equiv q\equiv 3\pmod 8$ with $(p/q)=1$, and $l$ a positive odd square-free integer relatively prime to $p$ and $q$.

Navigating the Dichotomy of Uncertainty in Green Innovation and Digital Supply Chains
Business Strategy and the Environment, EarlyView.ABSTRACT Amid growing environmental pressures and rapid technological disruption, understanding how digitalization reshapes corporate sustainability strategies has become increasingly vital. Supply chain digitalization (SCD) plays a pivotal role in enhancing firms' adaptive capacity, operational transparency, and innovation efficiency.

Block diagonalization of (p, q)-tridiagonal matrices
In this article, we study the block diagonalization of (p,q)\left(p,q)-tridiagonal matrices and derive closed-form expressions for the number and structure of diagonal blocks as functions of the parameters pp, qq, and nn. This reduction enables efficient

The Canadian Journal of Chemical Engineering, EarlyView.Abstract Hybrid models (HMs) combine fundamental model (FM) equations with empirical components. These models can lead to improved predictions because they reduce process/model mismatch and can account for phenomena that are not considered in the FM equations.
