Nicotinamide suppresses cytosolic DNA-Driven immunity independent of NAD+ via epigenetic modulation

Dysregulation of cytosolic DNA-triggered IFN-I signaling is a key driver of autoimmune and autoinflammatory pathogenesis. Precise metabolic orchestration of cytokine signaling is critical for immune homeostasis, but the role of endogenous metabolites in fine-tuning IFN-I transcri...

Uniform Bounds for Digit-Appending Fibonacci Walks

Building on the work of Miller et al. [Fibonacci Quarterly, 2022], we show that it is impossible to "walk to infinity" along the Fibonacci sequence in any integer base $b\geq 2$ when at most $N$ digits are appended per step. Our proof method is base-independent, yielding the boun...

Exponential measurement error mitigation in quantum sampling

Abstract Measurement errors limit the fidelity of sampling-based quantum tasks, yet extending error mitigation to sampling remains challenging. Here, we introduce a simple and scalable repetition-based scheme that mitigates measurement errors directly at the sampling level. By en...

EquivSage: LLM-assisted Detection of EVM-Inequivalent Code Smells in Multi-chain Reuse Contracts

With the increasing development of Solidity contracts on Ethereum , more developers are reusing them on other compatible blockchains. However, developers may overlook the differences between the designs of the blockchain system, such as the Gas Mechanism and Consensus Protocol ,...

A Fully‐Connected Chip‐Integrated Reconfigurable Mode‐Pairing Quantum Key Distribution Network

ABSTRACT Quantum key distribution (QKD) provides an information‐theoretic security framework for building QKD networks (QNs). However, existing QN architectures face critical challenges: trusted‐node‐based designs inherently expose relay nodes to physical compromise, while entang...
