New hash function based on C-MD structure and chaotic neural network
网络与信息安全学报, 2023 In recent years, widely used hash algorithms such as MD5 and SHA-1 have been found to have varying degrees of security risks.The iterative structure of the SHA-2 algorithm is similar to that of SHA-1, making it vulnerable to attacks as well.Meanwhile ...

Long-term outcomes of coils embolization for superior hypophyseal artery aneurysms
Frontiers in Neurology, 2023 ObjectiveSuperior hypophyseal artery (SHA) aneurysms are intradural, and their rupture can result in subarachnoid hemorrhage. Considering the related surgical difficulty and anatomical restrictions, endovascular treatment (EVT) is considered the most ...

Effects of Stephania hainanensis alkaloids on MSU-induced acute gouty arthritis in mice
BMC Complementary Medicine and Therapies, 2021 Background Gout is initiated by the precipitation of monosodium urate (MSU) crystals within the joints and soft tissues, and it can eventually cause acute or chronic arthritis.

Rosita++: Automatic Higher-Order Leakage Elimination from Cryptographic Code [PDF]
, 2021 Side-channel attacks are a major threat to the security of cryptographic implementations, particularly for small devices that are under the physical control of the adversary. While several strategies for protecting against side-channel attacks exist, these often fail in practice due to unintended interactions between values deep within the CPU.

Secure Hash Algorithm-2 formed on DNA
Journal of the Egyptian Mathematical Society, 2019 We present a new version of the Secure Hash Algorithm-2 (SHA-2) formed on artificial sequences of deoxyribonucleic acid (DNA). This article is the first attempt to present the implementation of SHA-2 using DNA data processing.

Finding Collisions against 4-Round SHA-3-384 in Practical Time
IACR Transactions on Symmetric Cryptology, 2022 The Keccak sponge function family, designed by Bertoni et al. in 2007, was selected by the U.S. National Institute of Standards and Technology (NIST) in 2012 as the next generation of Secure Hash Algorithm (SHA-3).

Brain and Behavior, Volume 12, Issue 12, December 2022., 2022 Abstract Objective Patients with spontaneous subarachnoid hemorrhage (SAH) may develop refractory arterial cerebral vasospasm (CVS), which is the leading cause of death in SAH patients. This study explored the clinical diagnostic value of serum miR‐195‐5p levels in CVS after SAH (SAH + CVS) and its relationship with the prognosis of SAH + CVS.

Dynamic Friction Model for the Investigation of Stick‐Slip Oscillations
Chemical Engineering &Technology, Volume 46, Issue 1, Page 29-36, January 2023., 2023 An efficient dynamic friction model based on the Stribeck curve is presented, which allows to investigate the influencing parameters on the stick‐slip effect through finite element simulations. The simulation of a tribometer test proofs that the model correlates well with the tribometer test results.
