TriCheck: Memory Model Verification at the Trisection of Software, Hardware, and ISA

, 2017
Memory consistency models (MCMs) which govern inter-module interactions in a shared memory system, are a significant, yet often under-appreciated, aspect of system design.

A RISC-V Processor Designed For Security [PDF]

Advanced Computing and Communications, 2019
A microprocessor is as secure as its weakest module. Depending on the application, the weakest module may be present in the hardware, micro-architecture, or a vulnerability in the software. For instance in a web-server, the biggest threats occur due to software vulnerabilities and due to information leakage in shared micro-architecture components.

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

Evolutionary interplay between viruses and R‐loops

FEBS Letters, EarlyView.
Viruses interact with specialized nucleic acid structures called R‐loops to influence host transcription, epigenetic states, latency, and immune evasion. This Perspective examines the roles of R‐loops in viral replication, integration, and silencing, and how viruses co‐opt or avoid these structures.

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 ...

Glycosylation Gene Signatures as Prognostic Biomarkers in Glioblastoma

Annals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Objective Glioblastoma (GBM) is an aggressive brain tumor characterized by significant heterogeneity. This study investigates the role of glycosylation‐related genes in GBM subtyping, prognosis, and response to therapy. Methods We analyzed mRNA expression data and clinical information from The Cancer Genome Atlas (TCGA) and Gene Expression ...

Implementation and integration of Keccak accelerator on RISC-V for CRYSTALS-Kyber

ACM International Conference on Computing Frontiers, 2023
One of the key metrics used for defying the security of the Internet of Things (IoT) is data integrity, which mostly relies on the use of cryptographic hash functions. In the last years, the National Institute of Standards and Technology (NIST) announced

Understanding Contributors of Resilience in Youth With Childhood‐Onset Systemic Lupus Erythematosus Through a Socioecological Lens: A Mixed‐Methods Study

Arthritis Care &Research, EarlyView.
Objective This study aimed to identify themes contributing to resilience in childhood‐onset systemic lupus erythematosus (cSLE), distinguish between profiles of resilience, and examine how they relate to underlying themes and patient characteristics. Methods We conducted a mixed‐methods study of 21 patients with cSLE aged 11 to 19 years at a Canadian ...

Carbon Nanotube 3D Integrated Circuits: From Design to Applications

Advanced Functional Materials, EarlyView.
As Moore's law approaches its physical limits, carbon nanotube (CNT) 3D integrated circuits (ICs) emerge as a promising alternative due to the miniaturization, high mobility, and low power consumption. CNT 3D ICs in optoelectronics, memory, and monolithic ICs are reviewed while addressing challenges in fabrication, design, and integration.
