when emerging technologies such as search engine marketing (sem) face tasks that require human level intelligence, it is inevitable to use the knowledge repositories to endow the machine with the breadth of knowledge available to humans. keyword suggestion for search engine advertising is an important problem for sponsored search and sem that requires a goldmine repository of knowledge. a recen...

Stream cipher Hiji-Bij-Bij (HBB) was proposed by Sarkar at Indocrypt’03. This cipher uses cellular automata (CA). The algorithm has two modes: a basic mode (B) and a self-synchronizing mode (SS). This article presents the first attack on B mode of HBB using 128 bit secret key. This is a known-pliantext guess-then-determine attack. The main step in the attack guesses 512 bits of unknown out of t...

This paper considers a class of detection/localization problems in which the detector ooers multiple operating modes. The modes diier in their detection performance and geographical coverage: \focused" modes ooer higher detection performance but less coverage area than \broad search" modes. It is assumed that a signal source is to be detected and localized using a sequence of tests, each possib...

We present a search for b/EC double beta decay of Te performed with the CUORICINO experiment, an array of TeO2 cryogenic bolometers. After collecting 0.0573 kg . y of Te, we see no evidence of a signal and therefore set the following limits on the half-life: T1 m =2 > 1:9 . 10 y at 90% C.L. for the 0m mode and T 1=2 > 7:6 . 10 y at 90% C.L. for the 2m mode. These results improve the existing li...

SUMMARY With the wide application of next-generation sequencing (NGS) techniques, fast tools for protein similarity search that scale well to large query datasets and large databases are highly desirable. In a previous work, we developed RAPSearch, an algorithm that achieved a ~20-90-fold speedup relative to BLAST while still achieving similar levels of sensitivity for short protein fragments d...
