Charging plan casts a shadow on Japan's light beam

Rainforest metropolis casts 1,000-km defaunation shadow.

Tropical rainforest regions are urbanizing rapidly, yet the role of emerging metropolises in driving wildlife overharvesting in forests and inland waters is unknown. We present evidence of a large defaunation shadow around a rainforest metropolis. Using interviews with 392 rural fishers, we show that fishing has severely depleted a large-bodied keystone fish species, tambaqui (Colossoma macropo...

Structure Casts Light on mtDNA Replication

In this issue, Lee et al. (2009) present a crystal structure of the human mitochondrial DNA polymerase (POLgamma). The structure of this heterotrimeric enzyme lays a foundation for understanding how POLgamma mutations cause human mitochondrial disease and why some antiviral nucleoside analogs cause cellular toxicity.

A Novel Charging Plan for PEVs Aggregator Based on Combined Market and Network Driven Approach

With the large-scale production of plug-in electric vehicles (PEVs), a new entity, the PEV fleet aggregator manages charging and discharging processes of the vehicles. The main objective of an individual aggregator in interaction with electricity markets is maximizing its profit. In this paper, the performance of this aggregator in day-ahead and real-time electricity markets, considering (a) cu...

If a Tree Casts a Shadow Is It Telling the Time?

Physical processes are computations only when we use them to externalize thought. Computation is the performance of one or more fixed processes within a contingent environment. We reformulate the Church-Turing thesis so that it applies to programs rather than to computability. When suitably formulated agent-based computing in an open, multi-scalar environment represents the current consensus vi...
