Several analytical models of fully-adaptive routing have recently been proposed for wormhole-routed k-ary ncubes under the uniform traffic pattern. However, there has been hardly any model reported yet that deals with other important non-uniform traffic patterns, such as hot spots. As a result, most studies have resorted to simulation when evaluating the performance merits of adaptive routing. ...

We calculate the first vertex correction δΛ k to the bare vertex Λ • in the nearly antiferromagnetic spin fluctuation Fermi liquid theory of the cuprate superconductor YBa 2 Cu 3 O 7. It is calculated for k on the Fermi surface, and Q = (± π a , ± π a). We find that the dimensionless ratio |δΛ k |/Λ • , which parametrizes the vertex correction, is not small. It is a maximum for k = k h , where ...

Telecommunication switches implement overload controls to maintain call throughput and delay at acceptable levels during periods of high load. Existing work has mostly focused on controls under sustained overload–they do not meet the demands of modern telecommunication systems where the increased number of services and mobile subscribers often creates fast changing hot spots. We introduce new a...

The primary concern of this contribution is that accreting millisecond pulsars (AMXPs) show a much larger amount of information than is commonly believed. The three questions to be addressed are: 1. Is the apparent spin torque observed in AMXPs real ? 2. Why do we see correlations and anti-correlations between fractional amplitudes and timing residuals in some AMXPs ? 3. Why the timing residual...

Recent interest in the automatic processing of meetings is motivated by a desire to summarize, browse, and retrieve important information from lengthy archives of spoken data. One of the most useful capabilities such a technology could provide is a way for users to locate “hot spots” or regions in which participants are highly involved in the discussion (e.g. heated arguments, points of excitem...

We study a two-period duopoly game with capacity accumulation under demand uncertainty, production and time-to-build constraints. These considerations are relevant in network industries such as electricity markets and hot spot markets.We characterize and compare open-loop, Markov perfect and closed-loop Nash equilibrium investments.

Hot spots are energetically important residues at protein interfaces and they are not randomly distributed across the interface but rather clustered. These clustered hot spots form hot regions. Hot regions are important for the stability of protein complexes, as well as providing specificity to binding sites. We propose a database called HotRegion, which provides the hot region information of t...

The steroid and xenobiotic-responsive human pregnane X receptor (PXR) binds a broad range of structurally diverse compounds. The structures of the apo and ligand-bound forms of PXR are very similar, in contrast to most promiscuous proteins that generally adapt their shape to different ligands. We investigated the structural origins of PXR's recognition promiscuity using computational solvent ma...

We present low-resolution spectrophotometric optical observations of the eclipsing nova-like cataclysmic variable SW Sex, the prototype of the SW Sex stars. We observed the system when it was in an unusual low state. The spectrum is characterized by the presence of strong Heii and Civ emission lines as well as the normal single peaked Balmer emission lines. The radial temperature profile of the...

A new methodology called “sensor-based knowledge discovery”, which utilizes wearable sensors and statistical analysis, is proposed and evaluated. This methodology facilitates identifying new knowledge that can improve business outcome. It utilizes wearable sensors to unobtrusively capture people’s location, motion, and social interaction with others. The captured data is converted into multidim...
