On Cryptographic Assumptions and Challenges

We deal with computational assumptions needed in order to design secure cryptographic schemes. We suggest a classi£cation of such assumptions based on the complexity of falsifying them (in case they happen not to be true) by creating a challenge (competition) to their validity. As an outcome of this classi£cation we propose several open problems regarding cryptographic tasks that currently do n...

Challenges in pig artificial insemination.

Semen extended in a liquid state, together with conventional artificial insemination (AI), is the sole sperm technology used by the pig industry. Sperm technologies known for many years, such as cryopreservation, and others developed during recent years, such as sperm sexing, have not yet been integrated into commercial use. Moreover, there has recently been an explosion of new technologies, su...

Ectopic calcification around joints of paralysed limbs in hemiplegia, diffuse brain damage, and other neurological diseases.

Mechanical deformity associated, with neurological disease is commonly encountered in the form of contractures, or pre-existing arthritis. Less common is the occurrence of ectopic calcification around the joints of a paralysed limb. Two forms of this are presented in a series of twenty patients. Para-articular calcification with the appearance of myositis ossificans around large joints of the a...
