Patients with Parkinson's disease have symptom of walking disorders which can be alleviated by surgery. By evaluating gait kinematics, the effect of medical treatment can be quantitatively assessed. In this paper, a method using image markers based on rigid body was introduced to set markers on anatomy key points of human lower limbs, which efficiently(More)
LBlock is a 32-round lightweight block cipher with 64-bit block size and 80-bit key. This paper identifies 16-round related-key impossible differentials of LBlock, which are better than the 15-round related-key impossible differentials used in the previous attack. Based on these 16-round related-key impossible differentials, we can attack 23 rounds of(More)
In this paper, we reveal a fundamental property of block ciphers: There can exist linear approximations such that their biases ε are deterministically invariant under key difference. This behaviour is highly unlikely to occur in idealized ciphers but persists, for instance, in 5-round AES. Interestingly, the property of key difference invariant bias is(More)
In the present study, we explored the association of serum angiopoietin-like protein 2 (ANGPTL2) levels with insulin sensitivity and serum epinephrine levels in metabolically healthy but obese (MHO) subjects. We also investigated the effects of epinephrine on ANGPTL2 expression in adipocytes in vitro. We examined the metabolic characteristics and serum(More)
Group decision-making (GD) is a fuzzy problem with high complexity and difficult to be handled. Usually the rule-based Group decision-making Support System (GDSS) is used to solve GD problem. But the definition of fuzzy rules and membership functions in GDSS are generally affected by subjective decision. So the rationality of GDSS is difficult to be judged.(More)
