Integration of Cholesterol Oxidase‐Based Biosensors on a Smart Contact Lens for Wireless Cholesterol Monitoring from Tears

Advanced Intelligent Systems, EarlyView.
The combination of a parity‐time symmetry wireless technology with a cholesterol sensor integrated into a smart contact lens enables high‐sensitivity cholesterol sensing at low concentration. Cholesterol plays a critical role in physiological functions, but elevated levels increase the risk of cardiovascular disease.

Tunable Endo/Exo Selectivity in Direct Catalytic Asymmetric 1,3‐Dipolar Cycloadditions with Polyfunctional Lewis Acid / Azolium‐Aryloxide Catalysts

Angewandte Chemie International Edition, Accepted Article.
Catalytic asymmetric 1,3‐dipolar cycloadditions (1,3‐DCA) using iminoesters as ylide precursors offer a powerful approach to accessing stereochemically complex, biologically relevant pyrrolidines. While previous studies have already achieved impressive stereoselectivities, catalytic productivity remains a challenge, with turnover numbers (TON ...

On the number of Hamiltonian cycles in tournaments

Discrete Mathematics, 1980
AbstractThe main results assert that the minimum number of Hamiltonian bypasses in a strong tournament of order n and the minimum number of Hamiltonian cycles in a 2-connected tournament of order n increase exponentially with n. Furthermore, the number of Hamiltonian cycles in a tournament increases at least exponentially with the minimum outdegree of ...

Quantum Anomalies in Condensed Matter

Advanced Physics Research, EarlyView.
Quantum materials provide a fertile ground in which to test and realize quantum anomalies predicted by quantum field theory. Quantum anomalies need to be canceled globally, however, quantum states with a quantum anomaly can exist at the boundary of topological materials.

In‐Situ EPR Study of the Effect of SO2 Poisoning and Regeneration of Cu‐CHA Catalysts

ChemCatChem, EarlyView.
In‐situ electron paramagnetic resonance highlights and quantifies the changes in the redox properties of copper chabazite catalysts for the SCR reaction after poisoning with SO2 and after regeneration at high temperature. Abstract A series of copper (Cu) exchanged chabazite zeolite with different Cu content were investigated to elucidate the effect of ...

Bifurcation of Limit Cycles by Perturbing a Piecewise Linear Hamiltonian System

Abstract and Applied Analysis, 2013
This paper concerns limit cycle bifurcations by perturbing a piecewise linear Hamiltonian system. We first obtain all phase portraits of the unperturbed system having at least one family of periodic orbits.

Enumeration of Hamiltonian cycles on a thick grid cylinder - part I: Non-contractible Hamiltonian cycles

Applicable Analysis and Discrete Mathematics, 2019
In a recent paper, we have studied the enumeration of Hamiltonian cycles (abbreviated HCs) on the grid cylinder graph Pm+1 x Cn, where m grows while n is fixed. In this sequel, we study a much harder problem of enumerating HCs on the same graph only this time letting n grow while m is fixed.

Engineering Tunable Dual‐Dependent Emission in Co‐Doped Cs7Cd3Br13 Perovskites

Carbon Energy, EarlyView.
Pb2+ and Sb3+ ions preferentially occupy octahedral sites, with Pb2+ achieving 93.7% PLQY and excellent X‐ray scintillation. Differing optical sensitivities of [PbBr6]4− and [SbBr6]3− enable versatile optical anticounterfeiting and encryption strategies.

The Hamiltonian and Hypohamiltonian of Generalized Petersen Graph (GP_(n,9))

Jambura Journal of Mathematics
The study of Hamiltonian and Hypohamiltonian properties in the generalized Petersen graph GP_{n,k} is interesting due to the unique structure and characteristics of these graphs. The method employed in this study involves searching for Hamiltonian cycles

Relaxing amid Three: Slow Magnetization Relaxation in Three‐Coordinate Chromium(II) N‐Heterocyclic Carbene Complexes

Chemistry – A European Journal, EarlyView.
Some members of a family of three‐coordinate S = 2 CrII complexes bearing NHC and amido donors display field‐induced slow magnetization relaxation. Magnetostructural correlations are drawn within this family, and comparisons are made with literature CrII SIMs. Abstract Three‐coordinate, paramagnetic CrII complexes of type [Cr(amido)nBnm(NHC)], NHC = N,
