Advanced Energy Materials, EarlyView.Counter‐halide engineering of fluorobenzylammonium surface passivators reveals bromide as the optimal partner for wide‐bandgap perovskites. FBz–Br effectively stabilizes halide‐vacancy‐related defects and undercoordinated Pb sites, suppresses non‐radiative recombination, and enhances surface hydrophobicity and thermal stability.

Advanced Energy Materials, EarlyView.Replacing toxic NiOx with phenyl‐substituted phosphonic‐acid carbazole monolayers (Ph‐5PACz) yields inverted perovskite solar cells that are efficient and recyclable. The nickel‐free interface reaches 25.3% efficiency and enables closed‐loop ITO recovery with near‐98% performance retention, while life‐cycle and techno‐economic analyses confirm lower ...

A Class of Simple Distribution-free Rank-based Unit Root Tests (Revision of DP 2010-72) [PDF]
We propose a class of distribution-free rank-based tests for the null hypothesis of a unit root. This class is indexed by the choice of a reference density g, which needs not coincide with the unknown actual innovation density f.

Delaying the Inevitable? U.S. Screwworm Closures and Feeder Cattle Market Dynamics
Applied Economic Perspectives and Policy, EarlyView.ABSTRACT Biosecurity trade restrictions are commonly framed as preventive measures, yet in many settings they function primarily as policies of delay: they impose immediate market costs while only postponing the arrival of biological risks. This paper evaluates that intertemporal tradeoff using the 2024–2025 US suspension of live cattle imports from ...

Optimality gaps in asymptotic dimensioning of many-server systems
, 2016 The Quality-and-Efficiency-Driven (QED) regime provides a basis for solving asymptotic dimensioning problems that trade off revenue, costs and service quality. We derive bounds for the optimality gaps that capture the differences between the true optimum

Asymptotically Optimal Smoothing with Arch Models [PDF]
Econometrica, 1996 Summary: Suppose an observed time series is generated by a stochastic volatility model -- i.e., there is an unobservable state variable controlling the volatility of the innovations in the series. As shown by the author [J. Econom. 52, No. 1/2, 61-90 (1992; Zbl 0761.62169)], and the author and \textit{D. P. Foster} [Econometrica 62, No.

Agribusiness, EarlyView.ABSTRACT Food systems have a significant impact on environmental sustainability, underscoring the need for innovative technologies to support more sustainable agricultural methods. However, the adoption of these technologies hinges on consumer acceptance, making the analysis of consumer perceptions essential.
