Logging is a simple yet surprisingly versatile and powerful implementation technique. Since its invention and popularization as a recovery technique for transactional databases [3], it has been used for a variety of other purposes such as updating meta-data in file systems [4], exploiting write-once media [2, 12], maintaining authentication audit trails [10], and increasing the write bandwidth ...

V enous thrombosis is a fairly common disorder that manifests mainly as deep vein thrombosis of the leg or pulmonary embolism. It affects 1 in 1000 individuals annually and has a substantial mortality rate. 1 Its causes are both genetic (prothrombotic abnormalities sometimes referred to as a group as thrombophilia) and acquired. 2 Among the latter are cancer, female hormone use, and all forms o...

We present coding methods for protecting against tampering of write-once optical disks which turns them into a secure digital medium for applications where critical information must be stored in a way that prevents or allows detection of an attempt at falsiication. Our method involves adding a small amount of redundancy to a modulated sector of data. This extra redundancy is not used for normal...

The rapid prosperity and future prospects of this colony are to me, not understanding these subjects, very puzzling. The two main exports are wool and whale oil, and to both of these productions there is a limit. Pasture everywhere is so thin that settlers have already pushed far into the interior: moreover the country further inland becomes extremely poor. Agriculture, on account of the drough...

The thesis is an exploration of the relations between know-how, abilities, and ordinary knowledge of facts. It is shown that there is a distinctively practical sort of know-how and a corresponding interpretation of 'S knows how to 0', and that this special sort of know-how, while possessing representational content, is not simply ordinary knowledge-that. The view rests on a novel distinction be...

OBJECTIVES To analyse the total number of newspaper articles citing the four leading general medical journals and to describe national citation patterns. DESIGN Quantitative content analysis. SETTING/SAMPLE Full text of 22 general newspapers in 14 countries over the period 2008-2015, collected from LexisNexis. The 14 countries have been categorised into four regions: the USA, the UK, Wester...

The ability to monitor computer file systems for unauthorized changes is a powerful administrative tool. Ideally this task could be performed remotely under the direction of the administrator to allow on-demand checking, and use of tailorable reporting and exception policies targeted to adjustable groups of network elements. This paper introduces M-FICA, a Mobile File Integrity and Consistency ...

We describe how the compliance requirements for data retention from recent laws such as the US Sarbanes Oxley Act may be supported by a tamper-evident secure storage system based on probe storage with a patterned magnetic medium. This medium supports normal read/write operations by out-of-plane magnetisation of individual dots. We report on an experiment to show that in principle the medium als...

High capacity disks, especially optical ones, are commercially available. These disks are ideal for archiving large text data bases. In this work, we examine efficient searching techniques for such applications. We propose a unifying framework, which reveals the similarities between signature files and an inverted file using a hash table. Then, we design methods that combine the ease of inserti...
