Highly prized is the truly productive crime prevention strategy, one that lightens the load on an overworked criminal justice system and, more importantly, reduces the number of victims. But to prevent crimes—especially in hot spots (high-crime areas)—police must determine where and when crimes are likely to occur. Drawing primarily on data collected in the United Kingdom, this Research in Acti...

Fumaroles (steam vents) are the most common, yet least understood, microbial habitat in terrestrial geothermal settings. Long believed too extreme for life, recent advances in sample collection and DNA extraction methods have found that fumarole deposits and subsurface waters harbor a considerable diversity of viable microbes. In this study, we applied culture-independent molecular methods to e...

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.
