Fluorophobic Effect Enables Selective Detection of PFAS in Water with Electrolyte‐Gated Organic Transistors

Advanced Functional Materials, EarlyView.
PerFluoroAlkyl Substances (PFAS) are responsible of major and persistent environmental pollution worldwide. This work demonstrates an ultra‐sensitive sensor for PFAS based on an organic transistor whose gate is functionalized with a binary self‐assembled monolayer containing a perfluorinated molecule.

Does military spending affect inequality in South Africa? A revisit

Cogent Economics & Finance
Previous investigations on the military spending-inequality nexus (in South Africa) were underpinned by the assumption that military spending and inequality behaves in symmetric fashion and employed linear autoregressive distributed lag (ARDL) model in ...

Non‐Hermitian Topological Lattice Photonics: An Analytic Perspective

Advanced Photonics Research, EarlyView.
This review establishes exact analytical solutions for non‐Hermitian Hatano–Nelson, Su–Schrieffer–Heeger, and generalized Rice–Mele models. We demonstrate non‐Hermitian skin effects via point‐gap topology, hybrid skin‐topological edge states in 2D lattices, and spin‐polarized boundary modes governed by dual bulk‐boundary correspondence.

Experimental Test of the Three‐Setting Clauser–Horne–Shimony–Holt Inequality with Nonmaximally Orbital Angular Momentum Entangled States

Advanced Photonics Research, EarlyView.
Herein, the maximum violation of the three‐setting Clauser–Horne–Shimony–Holt (CHSH) inequality using nonmaximally entangled photons with orbital angular momentum is demonstrated. By mapping the optimization problem to maximizing a triangle's perimeter inscribed in an ellipse, the experiment validates the geometric approach and highlights the ...

Robust Exponential Converge Controller Design for a Unified Chaotic System with Structured Uncertainties via LMI

Discrete Dynamics in Nature and Society, 2010
This paper focuses on the chaos control problem of the unified chaotic systems with structured uncertainties. Applying Schur-complement and some matrix manipulation techniques, the controlled uncertain unified chaotic system is then transformed into the ...

Consistency of a linear system of inequalities [PDF]

Journal of Optimization Theory and Applications, 1986
We show that a consistency check of a linear system of inequalities Ax\(\leq b\) reduces to check whether Qb\(\geq 0\) for a certain matrix Q. It is a direct consequence of the Farkas-Minkowski theorem. Thus, when one has to check consistency for different values of b, one need not run a numerical algorithm for each b.

Role of the Setae in an Ectoparasitic Seal Louse in Reducing Surface Drag: Numerical Modeling Approach

Advanced Theory and Simulations, EarlyView.
The seal louse Echinophthirius horridus has uniquely shaped setae that may reduce drag during its host's dives. Using numerical simulations, this study demonstrates that their natural inclination promotes vortex formation, minimizing friction and energy loss. These findings provide insights into biological surface adaptations and may inspire the design

On dissipation inequalities and linear viscoelasticity [PDF]

Quarterly of Applied Mathematics, 1965
Abstract : The purpose of this paper is to derive restrictions which must be placed on the relaxation integral law of linear viscoelasticity theory in order that it satisfy certain 'thermodynamic' requirements.

Generation of High‐Brilliance Polarized γ‐Rays Via Vacuum Dichroism‐Assisted Vacuum Birefringence

Advanced Science, EarlyView.
A novel method is proposed for generating such γ‐photon beams via the vacuum‐dichroism‐assisted quantum vacuum birefringence effect, only utilizing well‐established unpolarized electron beams and solving the critical problem of demanding polarized ones.

Bioprinted Organoids: An Innovative Engine in Biomedicine

Advanced Science, EarlyView.
Bioprinted organoids refer to either the printing of stem cells into tissue shape and subsequent differentiate into organoids, or assembling induced organoids as bioinks to replicate native organ. It enables the creation of miniaturized organs with complex architectures and physiological functions, potentially enhancing reproducibility, throughput, and
