GATOR-V: Accelerating the RISC-V Confidential Computing Ecosystem With a Production-Grade TEE

IEEE Access
Trusted Execution Environments (TEEs) have become essential for securing sensitive computations across modern computing platforms. While the open RISC-V architecture offered promising opportunities for security innovation, the ecosystem had lacked a ...

RISC-V3: A RISC-V Compatible CPU With a Data Path Based on Redundant Number Systems

IEEE Access, 2021
Redundant number systems (RNS) are a well-known technique to speed up arithmetic circuits. However, in a complete CPU, arithmetic circuits using RNS were only included on subcircuit level e.g. inside the Arithmetic Logic Unit (ALU) for realization of the

Reverse Intersystem Crossing and Exciton Harvesting: A Pathway to Low Threshold in Multi‐Resonant TADF Electrically Pumped Organic Semiconductor Lasers

Advanced Optical Materials, EarlyView.
Electrically pumped organic lasing thresholds are lowered by mitigating triplet accumulation through a tailored host‐guest system. Integrating the multi‐resonant TADF emitter DABNA‐2 into a triplet‐scavenging BSBCz host suppresses singlet‐triplet annihilation.

From SW Timing Analysis and Safety Logging to HW Implementation: A Possible Solution with an Integrated and Low-Power Logger Approach

Journal of Low Power Electronics and Applications, 2023
In this manuscript, we propose a configurable hardware device in order to build a coherent data log unit. We address the need for analyzing mixed-criticality systems, thus guaranteeing the best performances without introducing additional sources of ...

Visible‐Light Photoprogrammable Transistors Enabled by an All‐Organic Triplet‐Sensitized Diarylethene Channel Layer

Advanced Optical Materials, EarlyView.
All‐organic channel‐layer OFETs are shown to enable visible‐light photoprogramming via triplet‐sensitized diarylethene switching. Preferential localization of the photoswitch and organic sensitizer in intercrystalline amorphous domains preserves polymer crystalline packing while ensuring short‐range Dexter‐type triplet–triplet energy transfer and solid‐

A Novel Function of Nonadecanoic Acid in Regulating Glucose Homeostasis

Advanced Science, EarlyView.
This study identifies the odd‐chain fatty acid C19:0 as an endogenous ligand of GPR120 that promotes glucose homeostasis via Gαq signaling. In obesity, elevated palmitic acid suppresses endogenous C19:0 production through a miRNA–PPARα–HACL1 pathway, offering a promising direction for understanding the role of OCFAs in human health.

Neuid: A Novel Neuron‐Enriched LncRNA that Connects Epigenetic Gene Silencing to Alzheimer's Disease

Advanced Science, EarlyView.
ABSTRACT The increasing evidence that non‐coding RNAs can become deregulated during pathogenesis is dramatically expanding the space for drug discovery beyond the protein‐coding genome. Long noncoding RNAs (lncRNAs) are emerging as key regulators of cellular function, yet most remain uncharacterized.

A buffer overflow detection and defense method based on RISC-V instruction set extension

Cybersecurity, 2023
Buffer overflow poses a serious threat to the memory security of modern operating systems. It overwrites the contents of other memory areas by breaking through the buffer capacity limit, destroys the system execution environment, and provides ...

Non‐Targeting shRNA‐Encoded Plasmid DNA Enhances Protective Immunity Through RIDD‐RIG‐I Signaling Pathway in the Zika Virus Animal Model

Advanced Science, EarlyView.
We present a novel DNA vaccine platform featuring intrinsic, non‐targeting dsRNA that significantly enhances immune responses by activating the regulated IRE1‐dependent decay‐RIG‐I signaling pathway. This research elucidates a previously uncharacterized mechanism for dsRNA‐mediated innate immune activation.
