On co-authorship for author disambiguation
No full textAuthor name disambiguation deals with clustering the same-name authors into different individuals. To attack the problem, many studies have employed a variety of disambiguation features such as coauthors, titles of papers/publications, topics of articles, emails/affiliations, etc. Among these, co-authorship is the most easily accessible and influential, since inter-person acquaintances represented by co-authorship could discriminate the identities of authors more clearly than other features. This study attempts to explore the net effects of co-authorship on author clustering in bibliographic data. First, to handle the shortage of explicit coauthors listed in known citations, a web-assisted technique of acquiring implicit coauthors of the target author to be disambiguated is proposed. Then, a coauthor disambiguation hypothesis that the identity of an author can be determined by his/her coauthors is examined and confirmed through a variety of author disambiguation experiments.

Rebound Attack on Reduced-Round Versions of JH
Full text linkJH, designed by Wu, is one of the 14 second-round candidates in the NIST Hash Competition. This paper presents the first analysis results of JH by using rebound attack. We first investigate a variant of the JH hash function family for d = 4 and describe how the attack works. Then, we apply the attack for d = 8, which is the version submitted to the competition. As a result, we obtain a semi-free-start collision for 16 rounds (out of 35.5) of JH for all hash sizes with 2179.24compression function calls. We then extend our attack to 19 (and 22) rounds and present a 1008-bit (and 896-bit) semi-free-start near-collision on the JH compression function with 2156.77(2156.56) compression function calls, 2152.28memory access and 2143.70-bytes of memory. © 2010 Springer-Verlag.status: Publishe
Dynamic control of coherent pulses via Fano-type interference in asymmetric double quantum wells RID F-2382-2011
No full textWe study the temporal and spatial dynamics of two light pulses, a probe and a switch, propagating through an asymmetric double quantum well where tunneling-induced quantum interference may be observed. When such an interference takes place, in the absence of the switch, the quantum well is transparent to the probe which propagates over sufficiently long distances at very small group velocities. In the presence of a relatively strong switch, however, the probe pulse is absorbed due to the quenching of tunneling-induced quantum interference. The probe may be made to vanish even when switch and probe are somewhat delayed with respect to one another. Conversely, our asymmetric double quantum well may be rendered either opaque or transparent to the switch pulse. Such a probe-switch "reciprocity" can be used to devise a versatile all-optical quantum interference-based solid-state switch for optical communication devices
Ultrafast all optical switching via tunable fano interference RID F-2382-2011
No full textTunneling induced quantum interference experienced by an incident probe in asymmetric double quantum wells can easily be modulated by means of an external control light beam. This phenomenon, which is here examined within the dressed-state picture, can be exploited to devise a novel all-optical ultrafast switch. For a suitably designed semiconductor heterostructure, the switch is found to exhibit frequency bandwidths of the order of 0.1 THz and response and recovery times of about 1 ps
Decay of stationary light pulses in ultracold atoms
No full textWe develop a general scheme for studying the optical response of ultracold atoms driven into a regime of standing-wave electromagnetically induced transparency. We rely on full numerical solutions of the Maxwell-Liouville equations without invoking secular and adiabatic approximations and arbitrary initial state assumptions. These approximations and assumptions can conceal, e.g., significant loss and diffusion responsible for the decay of stationary light pulses in cold atomic samples. The complex decay dynamics of a stationary light pulse is here analyzed in terms of higher-order spin and optical coherences that arise from nonlinear interactions of the stationary light pulse with the two counterpropagating components of a standing-wave driving field. Specific results for stationary light pulses in cold (87)Rb atoms have been discussed for temperature regimes where the residual Doppler broadening is negligible
