There is, I think, something ethereal about i —the square root of minus one. I remember first hearing about it at school. It seemed an odd beast at that time—an intruder hovering on the edge of reality.

Usually familiarity dulls this sense of the bizarre, but in the case of i it was the reverse: over the years the sense of its surreal nature intensified. It seemed that it was impossible to write mathematics that described the real world in …

I and i

抗原变异可使得多种致病微生物易于逃避宿主免疫应答。表达在感染红细胞表面的恶性疟原虫红细胞表面蛋白1（PfPMP1）与感染红细胞、内皮细胞、树突状细胞以及胎盘的单个或多个受体作用，在黏附及免疫逃避中起关键的作用。每个单倍体基因组var基因家族编码约60种成员，通过启动转录不同的var基因变异体为抗原变异提供了分子基础。

Resolving the molecular details of proteome variation in the different tissues and organs of the human body will greatly increase our knowledge of human biology and disease. Here, we present a map of the human tissue proteome based on an integrated omics approach that involves quantitative transcriptomics at the tissue and organ level, combined with tissue microarray-based immunohistochemistry, to achieve spatial localization of proteins down to the single-cell level. Our tissue-based analysis detected more than 90% of the putative protein-coding genes. We used this approach to explore the human secretome, the membrane proteome, the druggable proteome, the cancer proteome, and the metabolic functions in 32 different tissues and organs. All the data are integrated in an interactive Web-based database that allows exploration of individual proteins, as well as navigation of global expression patterns, in all major tissues and organs in the human body.

Cryptosystem designers frequently assume that secrets will be manipulated in closed, reliable computing environments. Unfortunately, actual computers and microchips leak information about the operations they process. This paper examines specific methods for analyzing power consumption measurements to find secret keys from tamper resistant devices. We also discuss approaches for building cryptosystems that can operate securely in existing hardware that leaks information.

Differential Power Analysis

A construction method for point divisible designs

The Generic Authentication Architecture (GAA) is a standardised extension to the mobile telephony security infrastructures that supports the provision of security services to network applications. We have proposed a generalised version of GAA which enables almost any pre-existing infrastructure to be used as the basis for the provision of generic security services, and have examined a GAA instantiation supported by Trusted Computing. In this paper we study another instantiation of GAA, this time building on the widely deployed EMV security infrastructure. This enables the existing EMV infrastructure to be used as the basis of a general-purpose authenticated key establishment service in a simple and uniform way, and also provides an opportunity for EMV-aware third parties to provide novel security services. We also discuss possible applications and issues of privacy and trust.

Building General-Purpose Security Services on EMV Payment Cards

The first part of this paper is devoted to explaining what key escrow is and why it exists, and attempts to put it into a historical context. The subsequent focus is primarily on key escrow schemes which will work in an international environment. The possibility of using conventional key distribution techniques to provide key escrow services in an international context is first considered, and the associated problems are explored. The 'Royal Holloway' (RH) key escrow scheme is then described in a way which is intended to clarify and motivate its design, and the properties of this scheme and some related schemes are considered.

Certain undesirable features are identified in the ‘Structural proven signer ordering’ multisignature scheme of Kotzanikolaou, Burmester and Chrissikopoulos. This scheme is a modification of a previous multisignature scheme due to Mitomi and Miyaji.
