An O(n log n) Algorithm for finding Dissimilar Strings (2007)

Sarmad Abbasi, Anirvan Sengupta

Let \Sigma be a finite alphabet and x 2 \Sigma n . A string y 2 \Sigma m is said to be k-dissimilar to x, if no k length substring of x is equal to any k length substring of y. We present an O(n log...

Geometry and topology of parameter space: investigating measures of robustness in regulatory networks

Markov random field models of multicasting in tree networks (2002)

Ramanan, Kavita, Sengupta, Anirvan, Ziedins, Ilze, Mitra, Partha

In this paper, we analyse a model of a regular tree loss network that supports two types of calls: unicast calls that require unit capacity on a single link, and multicast calls that require unit...

From Coupled Pendulums to Quantum Search (2001)

Grover, Lov K., Sengupta, Anirvan

Quantum search is a quantum mechanical technique for searching N possibilities in only sqrt(N) steps. This paper gives a fresh perspective on the algorithm in terms of a resonance phenomenon which is...

Discussion of a spin-cluster model for the low temperature phase of NaV_2O_5 (2000)

Trebst, Simon, Sengupta, Anirvan

We discuss magnetic excitations of a spin-cluster model which has been suggested to describe the low temperature phase of alpha'-NaV_2O_5. This model fulfills all symmetry criteria proposed by recent...

Engineering aspects of enzymatic signal transduction: photoreceptors in the retina (2000)

Peter B. Detwiler, Sharad Ramanathan, Anirvan Sengupta, Boris I. Shraiman

ABSTRACT Identifying the basic module of enzymatic amplification as an irreversible cycle of messenger activation/ deactivation by a “push-pull ” pair of opposing enzymes, we analyze it in terms...

Overscreened multi-channel SU(N) Kondo model : large-N solution and Conformal Field Theory (1997)

Parcollet, Olivier, Georges, Antoine, Kotliar, Gabriel, Sengupta, Anirvan

The multichannel Kondo model with SU(N) spin symmetry and SU(K) channel symmetry is considered. The impurity spin is chosen to transform as an antisymmetric representation of SU(N), corresponding to...

Kondo Quartet (1997)

Georges, Antoine, Sengupta, Anirvan

This article describes some recently obtained results on the low-energy properties of the "Kondo quartet" model of two spin-1/2 impurities interacting with two channels (flavours) of conduction...

An O(n log n) Algorithm for finding Dissimilar Strings (1996)

Sarmad Abbasi, Anirvan Sengupta

Introduction Let \Sigma be a finite alphabet and x 2 \Sigma n . A string y 2 \Sigma m is said to be k- dissimilar to x, if no length k substring of x is equal to any k length substring of y; that is,...

The role of chromosomal instability in tumor initiation

Nowak, Martin A., Komarova, Natalia L., Sengupta, Anirvan, Jallepalli, Prasad V., Shih, Ie-Ming, Vogelstein, Bert, ...

Chromosomal instability (CIN) is a defining characteristic of most human cancers. Mutation of CIN genes increases the probability that whole chromosomes or large fractions of chromosomes are gained...

Analysis of Escherichia coli Global Gene Expression Profiles in Response to Overexpression and Deletion of CspC and CspE

Phadtare, Sangita, Tadigotla, Vasisht, Shin, Weon-Hye, Sengupta, Anirvan, Severinov, Konstantin

The Escherichia coli cold shock protein CspA family consists of nine proteins (CspA to CspI), of which two, CspE and CspC, are constitutively produced at 37°C and are involved in regulation of...
