Using anisotropic diffusion for efficient extraction of sensor noise in camera identification

Each digital camera has an intrinsic fingerprint that is unique to each camera. This device fingerprint can be extracted from an image and can be compared with a reference device fingerprint to determine the device origin. The complexity of the filters proposed to accomplish this is increasing. In this note, we use a relatively simple algorithm to extract the sensor noise from images. It has the advantages of being easy to implement and parallelize, and working faster than the wavelet filter that is common for this application. In addition, we compare the performance with a simple median filter and assess whether a previously proposed fingerprint enhancement technique improves results. Experiments are performed on approximately 7500 images originating from 69 cameras, and the results are compared with this often used wavelet filter. Despite the simplicity of the proposed method, the performance exceeds the common wavelet filter and reduces the time needed for the extraction.     

商标侵权的判断标准:相似性与混淆可能性之关系

2013年商标法的重大修改之一是对商标侵权判断标准的修改。然而,规定商标侵权判断标准的商标法第57条第2项中的相似性与混淆可能性概念及两者之间的关系均是不清楚的。混淆可能性吸收相似性、混淆可能性内化于相似性以及以相似性为基础、以混淆可能性为限定条件成为世界各国或地区商标侵权判断标准的三种代表性立法例。从法理上看,商标的通信本质决定了混淆性商标使用会影响商标功能的发挥,商标法立法目的决定了混淆可能性是商标侵权判断的基本标准,商标权的基本权能决定了混淆可能性主要适用于商标和商品有一者不相同但近似或者类似的商标使用情形,维持公平竞争和自由竞争平衡的商标保护基本政策决定了混淆的程度是混淆可能性,相似性本身的重要性与历史传统的影响决定了相似性可以是商标侵权判断标准的重要内容。从我国商标侵权判断标准引入混淆可能性的基本动因来看,商标法第57条第2项所确立的商标侵权判断标准可以解释为以相似性为基础和前提、以混淆可能性为限定条件,而传统上内含于商标近似、类似商品、类似服务、商品与服务类似等概念的混淆可能性应该从这些概念中剥离。     

论身份混同背景下我国外资并购中国家安全审查程序的完善

我国现有的外资并购中的国家安全审查程序主要是站在资本输入大国的立场设计的,没有考虑到我国既是"引进来战略"下的资本输入大国,又是"走出去战略"下的资本输出大国的混同身份。已有的审查程序在启动审查、申报前磋商、重新启动审查等方面不完善,减缓协议、申报撤回、监督机制、权利救济机制等制度缺失。借鉴国外成熟的经验,考虑身份混同对审查程序的新要求,我国应完善关于启动审查、申报前磋商、重新启动审查的规定,增加减缓协议制度、申报撤回制度、监督机制、权利救济机制。     

How Language Can Influence Political Marketing Strategy and a Candidate's Image: Effect of Presidential Candidates' Language Intensity and Experience on College Students' Ratings of Source Credibility

The present study examines the effects of language intensity on presidential candidates' credibility. We manipulated language intensity levels and experience levels for hypothetical candidates for president of the United States. Manipulation checks confirmed the effectiveness of the experimental conditions. The dimensions of source credibility, character, and authoritativeness were confirmed using confirmatory factor analysis. Analysis of variance indicated that candidates using low-intensity language received higher scores on character than did candidates using high-intensity language. Experienced candidates received higher scores on authoritativeness than did inexperienced candidates. Implications for political marketing of candidates are discussed.     

Moral Teaching and Ethical Expression of Mrs.Warren's Profession

Mrs.Warren' Profession mainly tells how the relationship between Mrs.Warren and her daughter Vivie goes worse and even breaks up in the context of capitalism exploitation and oppression. Along with the ethical line of unaccomplished kinship, this article is to deconstruct its ethical knots of the ethical choice, ethical identity, and ethical confusion through presenting the ethical environment so as to explore its deep-hidden ethical root of unaccomplished good family relation ship.     

The Effect of Time on Bone Fluorescence: Implications for Using Alternate Light Sources to Search for Skeletal Remains

Bones fluoresce when exposed to certain wavelengths of shortwave light, and this property can be useful in locating and sorting skeletal remains in forensic contexts. The proteins in bone collagen are largely responsible for its fluorescent properties, but these proteins degrade and denature over time. This study examined the fluorescence of bones from four temporal groups (recent, semi‐recent, ancient, and historic) ranging from 0 to 1064 years before present. Specimens were photographed under 490 nm wavelength light, and fluorescence was quantified by converting intensity to a gray scale value based on the RGB color model using ImageJ^® software. Significant (p < 0.05) differences were found in mean fluorescence between all four temporal groups, and a 0.324 coefficient of correlation indicates a significant (inverse) relationship between fluorescence and time. Bone fluorescence decreases with time, but some fluorescence is retained even in older samples. Fluorescence can therefore be reliably used in many modern skeletal remains searches.     

现代化视角下的大学生之公民教育——对党的十七大报告的解读

胡锦涛总书记在党的十七大报告中提出:加强公民意识教育,树立社会主义民主法治、自由平等、公平正义理念。这既为加强公民教育指明了方向,也界定了公民教育的内涵。大学生公民教育是公民教育的重要一环。大学生公民教育的价值寓于人性、市场经济、人民主权、法治国家以及社会自治的必然要求中。大学生公民教育的内容包括公民道德的养成与公民价值观的塑造、公民知识的传播与公民参与技能的训练这两大方面。当前,应以《思想道德修养与法律基础》为蓝本践行大学生公民教育,造就现代公民。

A City‐wide Investigation of the Isotopic Distribution and Source of Tap Waters for Forensic Human Geolocation Ground‐truthing

Human geolocation is prefaced on the accuracy of the geographic precision of mapped isotopic values for drinking water. As most people live in cities, it becomes important to understand city water supplies and how the isotopic values uniquely reflect that city. This study investigated the isotopic distribution of δ²H and δ¹⁸O from sourced tap waters that were collected from across the Metro Vancouver (MV) area (n = 135). The results revealed that the isotopic values reflect their water sources with a range of 5.3‰ for δ¹⁸O_tap and 29.3‰ for δ²H_tap for MV. The results indicate that individual cities need higher resolution studies to determine their tap water isotopic ranges, and a good understanding of the water supply network itself for human geolocation work. With an extended high‐resolution understanding of each city, human tissue may be compared with more certainty for geolocation.     

Identification of Mobile Phone and Analysis of Original Version of Videos through a Delay Time Analysis of Sound Signals from Mobile Phone Videos

This study designs a method of identifying the camera model used to take videos that are distributed through mobile phones and determines the original version of the mobile phone video for use as legal evidence. For this analysis, an experiment was conducted to find the unique characteristics of each mobile phone. The videos recorded by mobile phones were analyzed to establish the delay time of sound signals, and the differences between the delay times of sound signals for different mobile phones were traced by classifying their characteristics. Furthermore, the sound input signals for mobile phone videos used as legal evidence were analyzed to ascertain whether they have the unique characteristics of the original version. The objective of this study was to find a method for validating the use of mobile phone videos as legal evidence using mobile phones through differences in the delay times of sound input signals.
