Long-term outcomes of coils embolization for superior hypophyseal artery aneurysms

open access: yesFrontiers 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 ...

New hash function based on C-MD structure and chaotic neural network

open access: yes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 ...

Preimage Attacks on Reduced Tiger and SHA-2 [PDF]

open access: yes, 2009
This paper shows new preimage attacks on reduced Tiger and SHA-2. Indesteege and Preneel presented a preimage attack on Tiger reduced to 13 rounds (out of 24) with a complexity of 2128.5. Our new preimage attack finds a one-block preimage of Tiger reduced to 16 rounds with a complexity of 2161. The proposed attack is based on meet-in-the-middle attacks.

A new hash family obtained by modifying the SHA-2 family [PDF]

open access: yesProceedings of the 4th International Symposium on Information, Computer, and Communications Security, 2009
In this work, we study several properties of the SHA-2 design which have been utilized in recent collision attacks against reduced round SHA-2. Small modifications to the SHA-2 design are suggested to thwart these attacks. The modified round function provides the same resistance to linearization attacks as the original SHA-2 round function, but ...

Application of multicomponent seismic in tight reservoir prediction of the first member of Jurassic Shaximiao Formation, Sichuan Basin, China

open access: yesJournal of Natural Gas Geoscience
As the most powerful tool for tight gas prediction and exploration in the second member of the Shaximiao Formation (Sha 2 Member) in the Sichuan Basin, the technique of bright spot fails to deliver satisfactory results in the Sha 1 Member. To address the
