Optimal Gain Selection for the Arbitrary‐Order Homogeneous Differentiator

International Journal of Robust and Nonlinear Control, EarlyView.
ABSTRACT Differentiation of noisy signals is a relevant and challenging task. Widespread approaches are the linear high‐gain observer acting as a differentiator and Levant's robust exact differentiator with a discontinuous right‐hand side. We consider the family of arbitrary‐order homogeneous differentiators, which includes these special cases.

Validation of Neural Network Controllers for Uncertain Systems Using the Keep‐Close Approach: Robustness Analysis and Safety Verification

International Journal of Robust and Nonlinear Control, EarlyView.
ABSTRACT The safety verification of neural network (NN) controllers operating in uncertain environments characterized by unmodeled dynamics, nonlinearities, and time delays remains a fundamental challenge in robust control analysis. This article introduces a novel method, termed Keep‐Close, for analyzing the performance and robustness of uncertain ...

Effect of Metal–Metal Distance on the Performance of Dual‐Atom Catalysts for the Oxygen Reduction Reaction: A Density Functional Theory and Micro‐kinetics Study

Small, EarlyView.
Density functional theory calculations and microkinetic modeling were carried out on 108 dual‐atom catalysts with varied metalmetal distances ranging from 2.2 to 3.5 Å. The results reveal that moderate spacing of around 3.0 Å promotes bridging oxygen adsorption and dissociative reduction pathways, weakens the hydroxylhydroperoxyl scaling relationship ...

Polymer Electrolyte–Cathode Surface Bonding Suppresses Oxygen Evolution and Cation Mixing in Ni‐Rich Layered Oxides for Lithium Batteries

Small, EarlyView.
Structural stability of NMC is enhanced by introducing strong Ni–Opolymer bonds, such as those in carbonate‐based (PTMC) electrolytes. Strong hybridization between surface Ni and polymer oxygen facilitates oxidation of undercoordinated Ni2+, thereby mitigating Li/Ni mixing and O2 evolution at deep delithiation states.

Competitive SELEX Strategy for High‐Affinity Aptamer Isolation and Enhanced Biosensing

Small, EarlyView.
A novel competitive SELEX strategy was developed to isolate high‐affinity aptamers by using a lower‐affinity competitor during the selection process. This approach enabled the identification of an aptamer with exceptional binding affinity, significantly improving target detection sensitivity.

Bi[IrBi6I12], Ag3[IrBi6I12], and BixCu3–3x[IrBi6I12]: Rock‐Salt Superstructures Based on Heavy‐Atom Clusters

Zeitschrift für anorganische und allgemeine Chemie, EarlyView.
New iridium‐containing bismuth subiodides based on cuboctahedral [IrBi6I12]3− clusters adopt chain‐like or rock‐salt‐related structure variants depending on the counter‐cations. Ag3[IrBi6I12] combines silver mobility at room temperature with long‐range ordering at low temperature, while DFT calculations reveal semiconducting behavior.

Correlative X‐ray imaging and fluorescence microscopy in hydrated environments

Journal of Synchrotron Radiation, EarlyView.
We present a combined imaging platform that integrates beamline‐compatible fluorescence microscopy with scanning small‐angle X‐ray scattering to enable sequential multimodal investigations of hydrated cells under near‐native conditions. We apply our method to ordered cytoskeletal structures in different cell types and demonstrate the direct correlation

What Does a Mixed‐Frequency Multivariate Beveridge‐Nelson Decomposition Tell us about the Australian Output Gap?*

Economic Record, EarlyView.
Economic indicators inform the assessment of economic slack for central banks, yet traditional output gap estimates are often limited by the substantial reporting lags of quarterly GDP. This paper extends a mixed‐frequency Bayesian vector autoregressive (MF‐BVAR) framework to the Australian economy by applying a multivariate Beveridge–Nelson (BN ...

The informal prisoner justice system: Classification, identification, and punishment of sex offenders behind bars

Criminology, EarlyView.
Abstract Drawing on 576 interviews with incarcerated men and 131 correctional staff across five Western Canadian prisons, we reconceptualize the prison code as subcultural law, documenting the “informal prisoner justice system” as its enforcement arm. Although scholars have treated the code primarily as cultural values prescribing loyalty, silence, and

Criminal history's expiration date: Evidence of prediction decay

Criminology, EarlyView.
Abstract Criminal history is a well‐established predictor of future offending, yet recidivism risk declines with time. Research has struggled to reconcile this tension as criminal history is often treated as a static indicator of risk, while desistance is commonly inferred rather than directly modeled.
