实验大鼠胃Kappa-阿片受体与死亡时间的相关性

目的研究实验大鼠餐后死亡不同时间段的胃主细胞Kappa-阿片受体(KOR)的表达变化。探讨其变化、表达规律与死亡时间(PMI)的相关性。方法实验雄性大鼠,随机分为对照组和实验组,进食后断颈处死后于不同时间提取组织检材,对组织进行免疫组织化学染色,采用图像分析软件测定阳性面积、积分光密度、平均光密度、平均灰度等参数,用SPSS统计软件对各参数与死亡时间的关系进行相关性分析。结果死后9d内的胃主细胞上Kappa-阿片受体随着死亡时间(PMI)的延长,其积分光密度和阳性面积与死亡时间(PMI)存在一定的相关回归关系。结论实验大鼠死后胃主细胞上Kappa-阿片受体的变化规律与死亡时间有相关性。     

Passive forensics in image and video using noise features: A review

Due to present of enormous free image and video editing software on the Internet, tampering of digital images and videos have become very easy. Validating the integrity of images or videos and detecting any attempt of forgery without use of active forensic technique such as Digital Signature or Digital Watermark is a big challenge to researchers. Passive forensic techniques, unlike active techniques, do not need any preembeded information about the image or video. The proposed paper presents a comprehensive review of the recent developments in the field of digital image and video forensic using noise features. The previously existing methods of image and video forensics proved the importance of noises and encourage us for the study and perform extensive research in this field. Moreover, in this paper, forensic task cover mainly source identification and forgery detection in the image and video using noise features. Thus, various source identification and forgery detection methods using noise features are reviewed and compared in this paper for image and video. The overall objective of this paper is to give researchers a broad perspective on various aspects of image and video forensics using noise features. Conclusion part of this paper discusses about the importance of noise features and the challenges encountered by different image and video forensic method using noise features.     

中国古代法律传播方式的演变

法律传播是特殊的法律活动,作为社会现象古已有之,它与法律同生长同发展。本文运用人类学、考古学、历史学、社会学、文字学、民族学,以及法学的研究成果,综合考察上古以迄三代之社会形态、语言文字和法律形式的发展历程,厘清中国古代法律传播方式的演变脉络,即经历了由“口耳相传”、到“图象显示”、到“形于文字”的三个阶段。     

The Legality of the Image

Intimate links exist between political power, law and images. Theology, philosophy and law have always developed elaborate rules about visuality. The iconophilic and iconoclastic traditions complemented one another and combined to construct subjectivity and to reconcile humanity with finitude. In modernity, law replaced religion and philosophy conceptualised legality through the aesthetic category of the sublime. The law understands the importance of the governance of images for the maintenance of the social bond and helps organise a regime of permitted images and forbidden idols which amounts to a complex legal administration of aesthetics and a related aesthetic organisation of law.

Explosion Scene Forensic Image Interpretation

Image interpretation is an important aspect in the field of forensic science; however, it is seldom reported how to use these techniques in explosion scene forensic investigations. On 12 August 2015, a series of explosions killed 165 people and injured hundreds more at a container storage station at the Port of Tianjin. In this study, we applied image interpretation methods to determine the seat of the explosion by analyzing low‐quality video clips of the event. The interpretation fits well with recently published standard operating procedures, including the hypothesis, evaluation, inference, and confirmation. Image processing was adopted to enhance the images while the explosion scene was reconstructed with the same images. Some important features were extracted and utilized to distinguish whether the flashes were caused by reflection or a real blast. We reveal the real explosion location, which guides the overall investigation. The results indicate that image interpretation is a powerful tool for forensic investigators to analyze low‐quality images in complicated explosions or fire accidents.     

From fragile to smart consumers: Shifting paradigm for the digital era

The use of digital technologies, functioning thanks to data processing, has been conquering many sectors of the world economy and it is possible that, in the near future, only a few markets will still be excluded from this industrial revolution. Therefore, even if one chose unreasonably to disregard the many innovations that the digital economy has brought about, its development seems quite inexorable, although it is true that this new stage in human progress raises some concerns. In particular, many worry about the millions of passive and powerless digital consumers who, facing a few huge and influential companies without any education or awareness, could succumb and find themselves poorer, victimized, and manipulated. The paper proposes to react to this state of affairs without further fueling the fear of the digital revolution and without the thought that regulation can be used only as a shield to protect fragile digital consumers. Rather, by taking inspiration from some regulatory actions undertaken by the European Union, the paper bears in mind that regulation can be used as a sword in the hands of consumers to finally assign them a lead role in digital markets. New rules to empower consumers and to make them take autonomous and independent decisions as to the management of their personal data as well as to the merits of digital firms can be envisaged. After all, one of the cultural roots of Western societies is that every individual should be enabled to be faber ipsius fortunae.     

If i Go There Will Be Trouble,If i Stay There Will Be Double: Revenge Porn,Domestic Violence,and Family Offenses

New York State's current lack of legislation criminalizing the threat of revenge porn allows repetitive, invasive, and embarrassing attacks on the morality and sexuality of victims. This can have a severe impact on survivors of domestic violence who are prevented from leaving dangerous situations by threats of dissemination. Victims of revenge porn and domestic violence often face isolation, threats of violence, and thoughts of suicide. This Note proposes that threats of revenge porn become family offenses under the New York Family Court Act § 812.
