Psychiatric symptoms associated with hypothyroidism are well recognised. The common mental manifestations are slowness and difficulty in apprehension, thought and action; psychomotor retardation with indecision and listlessness suggestive of a depressive syndrome.' ,2 What is perhaps less well recognised is that patients with hypothyroidism may also present with marked irritability, paranoid id...

This paper focuses on the slowness of diffusion of electronic commerce (EC), particularly in the business-to-consumer side. The theme is approached by analysing emerging Web-services in the travel services industry. We report on a field study of Web-sites of 294 travel agencies, tour operators and transportation services companies. By surveying and evaluating the current services we hope to she...

Hash algorithms generate a fixed-size output from a variable-size input. Typical algorithms will process every byte of the input to generate their output, which, on a very large input, can be time consuming. The hashes’ potential slowness, coupled with recently reported attacks on the MD5 and SHA-1 hash algorithms, prompted a look at hashing from a different perspective. By generating several “...

arkinson’s disease (PD) is one of the most common neurodegenerative diseases characterized by tremor, stiffness and slowness of motion due to dopamine (DA) depletion following dramatic loss of dopaminergic neurons in Substantia nigra. Unfortunately, this debilitating disease has no curative treatment. Neuroprotective agents might be useful via postponing the initiation of neurodegenerative proc...

Relevance Models are well known retrieval models and capable of producing competitive results. However, because they use query expansion they can be very slow. We address this slowness by incorporating two variants of locality sensitive hashing (LSH) into the query expansion process. Results on two document collections suggest that we can obtain large reductions in the amount of work, with a sm...
