A Random Oracle for All of Us [PDF]
, 2022 We introduce the notion of a universal random oracle. Analogously to a classical random oracle it idealizes hash functions as random functions. However, as opposed to a classical random oracle which is created freshly and independently for each adversary,

American Journal of Agricultural Economics, EarlyView.Abstract Preferential trade agreements (PTAs) contain various non‐tariff provisions, yet identifying their trade effects remains challenging because these commitments are high‐dimensional and strongly correlated within agreements. We estimated a theory‐consistent structural gravity model with domestic flows for 26 agricultural subsectors over 1988–2017

A Short Linearly Homomorphic Proxy Signature Scheme
IEEE Access, 2018 Linearly homomorphic signature schemes allow the performance of linear computations on authenticated data. They are important primitives for many applications, such as electronic voting, smart grids, electronic health records, and so on.

EcoEnergy, EarlyView.An overview of grain boundary engineering in the field of electrocatalysis. ABSTRACT Key electrocatalytic reactions such as HER, OER, ORR, CO2RR, and NRR offer promising routes for storing renewable energy as chemical fuels. However, their widespread application is constrained due to the lack of highly active and stable catalysts. Grain boundaries (GBs)

Epilepsia, EarlyView.Abstract Objective We aimed to determine the risk of subsequent seizure or epilepsy diagnosis after acute symptomatic seizures (ASyS) in critically ill children, evaluate whether antiseizure medication (ASM) use is associated with subsequent seizure/epilepsy diagnosis, and develop a simple Seizure/Epilepsy Risk Score to predict subsequent seizure ...

Revocable Certificateless Public Key Encryption With Outsourced Semi-Trusted Cloud Revocation Agent
IEEE Access, 2020 Certificateless public key cryptography (CL-PKC) not only eliminates the need for certificates in traditional certificate-based PKC but also solves the inherent key escrow problem in identity-based PKC.

On the Oracle Properties of Bayesian Random Forest for Sparse High-Dimensional Gaussian Regression
Mathematics, 2023 Random forest (RF) is a widely used data prediction and variable selection technique. However, the variable selection aspect of RF can become unreliable when there are more irrelevant variables than relevant ones.

Climate Risks and the Risk Premia of AI Stocks: Some Forecasting Experiments
Journal of Forecasting, EarlyView.ABSTRACT This study examines whether physical and transition climate‐risk measures predict the risk premia of AI‐related stocks, and whether incorporating these risks improves forecast performance relative to benchmark models. The findings suggest that global transition climate shocks lower the premia of AI stocks, while US climate policy increases ...
