Comparison of the effects of high tibial osteotomy with and without a tourniquet

Huiwen Wu, Fangyuan Wang, Shihao Deng, Shuai Liang et autres

BACKGROUND: Tourniquets are routinely employed to achieve hemostasis in modern limb surgeries. Nevertheless, the precise role and benefits of tourniquets in high tibial osteotomy (HTO) surgeries remain understudied. The aim of this study was to assess the application of tourniquets in high-tibial …

A Proof of unsecure in the polynomial time for the XOR of two random variables

Huiwen Wu, Chenglian Liu

Xoring (Exclusive-OR) two variables is a very simple way to build pseudorandom functions from pseudorandom permutations. The aim of this paper proves it may insecure for this type of form A⊕B when the two variables run XOR operation on specific environment. Because …

Learning with User-Level Local Differential Privacy

Puning Zhao, Li Shen, Rongfei Fan, Qingming Li et autres

User-level privacy is important in distributed systems. Previous research primarily focuses on the central model, while the local models have received much less attention. Under the central model, user-level DP is strictly stronger than the item-level one. However, under the local model, …

Enhancing Learning with Label Differential Privacy by Vector Approximation

Puning Zhao, Rongfei Fan, Huiwen Wu, Qingming Li et autres

Label differential privacy (DP) is a framework that protects the privacy of labels in training datasets, while the feature vectors are public. Existing approaches protect the privacy of labels by flipping them randomly, and then train a model to make the output …

Enhancing tube feeding method for neurosurgery: the application of improved PICC technique

Huiwen Wu, Yuru Qiu, Yucui Wang, Yihong Qiu

BACKGROUND AND PURPOSE: Peripherally inserted central catheter (PICC) used in neurosurgical patients requires changes in patients' head positions. However, such changes can worsen pressure on the brain tissue, lead to sudden acute brain herniation and respiratory arrest, resulting in a higher chance …
