Probing Electrocatalyst Design for Product Selectivity in CO2 Reduction

Advanced Science, EarlyView.
Selective CO2 electroreduction is controlled by catalyst structure, dynamic surface reconstruction, adsorbate interactions, and reaction microenvironment. This review summarizes Cu‐ and non‐Cu‐based catalysts, single‐atom and molecular systems, degradation pathways, and operando/computational strategies for steering CO2RR toward hydrocarbons ...

Cryptanalysis of PMACx, PMAC2x, and SIVx

IACR Transactions on Symmetric Cryptology, 2017
At CT-RSA 2017, List and Nandi proposed two variable input length pseudorandom functions (VI-PRFs) called PMACx and PMAC2x, and a deterministic authenticated encryption scheme called SIVx.

Spook: Sponge-Based Leakage-Resistant Authenticated Encryption with a Masked Tweakable Block Cipher

IACR Transactions on Symmetric Cryptology, 2020
This paper defines Spook: a sponge-based authenticated encryption with associated data algorithm. It is primarily designed to provide security against side-channel attacks at a low energy cost. For this purpose, Spook is mixing a leakageresistant mode of

Spatiotemporal Multi‐Omic Mapping Reveals Liver‐Muscle Metabolic Crosstalk in Cancer Cachexia

Advanced Science, EarlyView.
The interactive CCAtlas platform delineates cross‐species, spatiotemporal, and sex‐specific molecular dynamics and metabolic rewiring across organs during cancer cachexia. Hepatic Gamt downregulation curtails hepatic creatine synthesis to trigger systemic creatine insufficiency and consequent skeletal muscle atrophy in LLC tumour‐bearing mice ...

Local Search and the Evolution of World Models

Topics in Cognitive Science, EarlyView., 2023
Abstract An open question regarding how people develop their models of the world is how new candidates are generated for consideration out of infinitely many possibilities. We discuss the role that evolutionary mechanisms play in this process. Specifically, we argue that when it comes to developing a global world model, innovation is necessarily ...

Toward Practical Zn‐Ion Batteries Through Separator/Electrolyte Co‐Design

Advanced Science, EarlyView.
A hybrid organic–aqueous electrolyte enables thin commercial polypropylene separators to replace bulky glass‐fiber separators in practical Zn‐ion batteries. This electrolyte/separator co‐design improves wettability, promotes uniform Zn plating/stripping, and suppresses hydrogen evolution, resulting in 4360 h of symmetric‐cell cycling and stable Zn//NVO

ESTATE: A Lightweight and Low Energy Authenticated Encryption Mode

IACR Transactions on Symmetric Cryptology, 2020
NIST has recently initiated a standardization project for efficient lightweight authenticated encryption schemes. SUNDAE, a candidate in this project, achieves optimal state size which results in low circuit overhead on top of the underlying block cipher.

MMM: Authenticated Encryption with Minimum Secret State for Masking

Transactions on Cryptographic Hardware and Embedded Systems, 2023
We propose a new authenticated encryption (AE) mode MMM that achieves the minimum memory size with masking. Minimizing the secret state is the crucial challenge in the low-memory AE suitable for masking.
