As the fault‐based attacks are becoming a more pertinent threat in today's era of edge computing/internet‐of‐things,there is a need to streamline the existing tools for better accuracy and ease of use,so that we can gauge the attacker's power and a proper countermeasure can be devised in the long *** this regard,we propose a machine learning(ML)assisted tool that can be used in the context of a differential fault *** particular,finding the exact fault location by analysing the output difference(typically the XOR of the nonfaulty and the faulty ciphertexts)is somewhat *** the literature survey,we notice that the Pearson's correlation coefficient dominantly is used for this purpose,and has almost become the defacto *** this method can yield good accuracy for certain cases,we argue that an MLbased method is more powerful in all the situations we experiment *** sub-stantiate our claim by showing the relative performances(we choose the commonly used multilayer perceptron as our ML tool)with two variants of Grain‐128a(a stream cipher,and a stream cipher with authentication),the lightweight stream cipher LIZARD and the lightweight block cipher SIMON‐32(where the faults are injected at the fifth last rounds).Our results demonstrate that a common ML tool can outperform the correlation with the same training/testing *** believe that our work extends the state‐of‐the‐art by showing how traditional cryptographic methods can be replaced by a more powerful ML tool.

AIM： To compare the efficacy of pentoxifylline and prednisolone in the treatment of severe alcoholic hepatitis, and to evaluate the role of different liver function scores in predicting prognosis.METHODS： Sixty-eight patients with severe alcoholic hepatitis （Maddrey score ≥ 32） received pentoxifylline （n = 34, group Ⅰ） or prednisolone （n = 34, group Ⅱ） for 28 d in a randomized double-blind controlled study, and subsequently in an open study （with a tapering dose of prednisolone） for a total of 3 mo, and were followed up over a period of 12 mo.RESULTS： Twelve patients in group Ⅱ died at the end of 3 mo in contrast to five patients in group Ⅰ. The probability of dying at the end of 3 mo was higher in group Ⅱ as compared to group Ⅰ （35.29% vs 14.71%, P = 0.04; log rank test）. Six patients in group I developed hepatorenal syndrome as compared to none in group Ⅰ. Pentoxifylline was associated with a significantly lower model for end-stage liver disease （MELD） score at the end of 28 d of therapy （15.53± 3.63 vs 17.78± 4.56, P=0.04）. Higher baseline Maddrey score was associated with increased mortality.CONCLUSION： Reduced mortality, improved risk-benefit profile and renoprotective effects of pentoxifylline compared with prednisolone suggest that pentoxifylline is superior to prednisolone for treatment of severe alcoholic hepatitis.

Background: D-Limonene, a monoterpene from citrus fruit has been found to have chemopreventive and chemotherapeutic activities in various types of cancers. In this study, we evaluated the in vivo effect of D-Limonene on a K562-induced model of chronic myeloid leukemia(CML) in C57 BL/6 ***: The tail vein injection model of K562 cells in immunocompromised C57 BL/6 mice was developed and evaluated for characteristics of the disease. The mice were treated with D-Limonene and evaluated for haematological parameters. We also evaluated the effect of D-Limonene on angiogenesis using the chick chorioallantoic membrane(CAM) ***: In a complete blood count, a significant dose-dependent reduction in white blood cell, neutrophil and lymphocyte counts, but an elevation in red blood cell count and haemoglobin content was observed with D-Limonene treatment compared to the disease control or untreated group. In the CAM assay, D-Limonene produced a significant dose-dependent reduction in number of blood vessels in treatment groups compared to the vehicle-treated ***: These studies suggest promising anti-leukemic and anti-angiogenic effects of D-Limonene in the treatment of CML.

Livesport的新办公室建在以前的楼层上,一个将体育与现代技术融为一体的空间。设计灵感来自于训练中的艰苦努力,准备过程中的自我提升。健身房空间由方块地毯表示,无缝天花板上分布规则的聚光灯网格。三个主要元素进一步增强空间,分别是地板线条、运动器材和电子笔,它们是从设计元素中抽象出来的,线条划分办公室不同区域,运动器材增强使用体验,电子笔则是导航系统,帮助新来的运动员快速融入团队与比赛。

多巴胺(DA)激动剂和拮抗剂对脑中儿茶酚胺和DA 代谢的研究报道很多。而对肾上腺中儿酚胺浓度,特别是对DA 浓度影响的报道甚少。据推测肾上腺中DA 浓度能反映去甲肾上腺素(NA)和肾上腺素(A)的更新情况。且多巴胺激动剂和拮抗剂用于治疗神经学科方面的疾病日益增多,故作者研究其激动剂溴隐亭和拮抗剂氟哌啶醇对这方面的影响。实验用150—200g 雄性大鼠,每组四只。溴隐亭和氟哌啶醇的剂量安排是:

目的研究旨在应用心脏MR(CMR)成像评估急性ST段抬高性心肌梗死(STEMI)后心肌存活力与并发的可逆性收缩功能障碍之间的关系。方法 34例急性STEMI病人,接受经皮冠状动脉介入治疗(PPCI)1～7d后行CMR检查,并于1年后随访。以T2加权成像评估缺血风险区(AAR),对比剂延迟强化评估心肌坏死。通过磁化互补空间调制(CSPAMM)量化心肌收缩力。结果 PPCI术后短期内,心肌存活力指数低(<25%)或中等(26%～50%)的心肌缺血段的欧拉圆周(Ecc)收缩力[分别为(-9.1±0.6)%,P=0.033和(-11.8±1.3)%,P=0.003]比那些心肌存活指数高(51%～100%)的缺血段的收缩力[(-14.4±1.3)%]差。1年后随访的缺血心肌的平均收缩力较首次提高[(-16.2±0.5)%∶(-10.1±0.5)%,P<0.0001]。尽管存活力差的节段1年后仍有大部分功能受损,但其心肌收缩力仍有所改善[分别为(-9.1±0.6)%和(-15.3±0.6)%,P=0.033]。结论 PPCI术后,即使存活力低于25%,仍可观察到收缩力峰值的部分恢复。对比剂延迟强化(LGE)并不等同于不可逆的心肌损伤,血管重建后1周内的心肌存活力评估可能低估心功能恢复潜力。要点①MRI可以衡量心脏病发作后心肌受损程度。②最初表现为坏死的心肌有时可以部分恢复。③梗死边缘的强化可随时间的推移而消散。④应用MRI评估预防性心脏治疗时要注意其局限性。
