PURPOSE To compare the MR findings of eight cases with clinical diagnosis of Hallervorden-Spatz disease (HSD) with the pathologic findings of two other cases of HSD. MATERIALS AND METHODS The eight imaged cases were studied with 0.5-T (seven cases) and/or 1.5-T (five cases) units. Six patients also had CT scans. The two other cases with proven HSD had detailed histologic evaluation. RESULTS...

In this paper we discuss the construction, features and intended uses of the TiGer DB. The TiGer DB is a dependency bank derived from the TiGer Treebank containing predicate-argument relations and several grammatical features which can be considered as semantically meaningful. It is produced semi-automatically by the conversion of the TiGer treebank into an LFG f-structure bank, which then in t...

AIMS Human-tiger conflict (HTC) is a serious public health issue in Sundarban Reserve Forest, India. HTC is a continued concern for the significant mortality and morbidity of both human and tiger population. This is the first comprehensive report on Sundarban tiger-human conflicts and its impact on widows whose husbands were killed by tigers. The study attempts to explore the situation analysis...

Although significantly more money is spent on the conservation of tigers than on any other threatened species, today only 3200 to 3600 tigers roam the forests of Asia, occupying only 7% of their historical range. Despite the global significance of and interest in tiger conservation, global approaches to plan tiger recovery are partly impeded by the lack of a consensus on the number of tiger sub...

The cryptanalysis of the cryptographic hash function Tiger has, until now, focussed on finding collisions. In this paper we describe a preimage attack on the compression function of Tiger-12, i.e., Tiger reduced to 12 rounds out of 24, with a complexity of 2 compression function evaluations. We show how this can be used to construct second preimages with complexity 2 and first preimages with co...

INTRODUCTION Transradial coronary angiography (TRC) can be performed with a one-catheter approach for the right and left coronary ostium (R/LCO). We investigated the performance of a special diagnostic catheter widely used for the one-catheter-approach, the Tiger (Tiger II, TerumoTM). METHODS In a dual center registry we analyzed 1412 TRC-procedures exclusively performed by experienced TRC-op...

Tiger is a cryptographic hash function with a 192-bit hash value which was proposed by Anderson and Biham in 1996. At FSE 2006, Kelsey and Lucks presented a collision attack on Tiger reduced to 16 (out of 24) rounds with complexity of about 2. Furthermore, they showed that a pseudo-near-collision can be found for a variant of Tiger with 20 rounds with complexity of about 2. In this article, we ...

Tiger is a cryptographic hash function with a 192-bit hash value. It was proposed by Anderson and Biham in 1996. Recently, weaknesses have been shown in round-reduced variants of the Tiger hash function. First, at FSE 2006, Kelsey and Lucks presented a collision attack on Tiger reduced to 16 and 17 (out of 24) rounds with a complexity of about 2 and a pseudo-near-collision for Tiger reduced to ...
