When searching for information, people often seek help from others. However, while people can benefit from communicating with others, they can usually satisfy their information needs, to some degree, without help. Because establishing explicit collaborations is often seen as onerous, there are many missed opportunities where shared experiences could save time and effort. In this work, we propos...

The use of similarities has been one of the main approaches to resolve the ambiguities of coordinate structures. In this paper, we present an alternative method for coordination disambiguation, which does not use similarities. Our hypothesis is that coordinate structures are supported by surrounding dependency relations, and that such dependency relations rather yield similarity between conjunc...

Let A be a basis for N0 of some order. By an essentiality of A one means a subset P such that A\P is no longer a basis (of any order) and such that P is minimal among all subsets of A with this property. In a recent paper, Deschamps and Farhi asked whether every basis of N0 possesses some such subset. We construct, for every integer h ≥ 2, a basis of order h with no essentialities.

The absolute privacy of the secret-keys associated with cryptographic algorithms has been the corner-stone of modern cryptography. Still, in practice, keys do get compromised at times for a variety or reasons. A particularly disturbing loss of secrecy is as a result of side channel attacks. These attacks exploit the fact that every cryptographic algorithm is ultimately implemented on a physical...

Data mining is an appropriate way to discover information and hidden patterns in large amounts of data, where the hidden patterns cannot be easily discovered in normal ways. One of the most interesting applications of data mining is the discovery of diseases and disease patterns through investigating patients' records. Early diagnosis of diabetes can reduce the effects of this devastating disea...
