The Sequence of the Human Genome

A 2.91-billion base pair (bp) consensus sequence of the euchromatic portion of the human genome was generated by the whole-genome shotgun sequencing method. The 14.8-billion bp ...

The Genome Sequence of the Malaria Mosquito <i>Anopheles gambiae</i>

Anopheles gambiae is the principal vector of malaria, a disease that afflicts more than 500 million people and causes more than 1 million deaths each year. Tenfold shotgun seque...

Diffusion in disordered media

Abstract Diffusion in disordered systems does not follow the classical laws which describe transport in ordered crystalline media, and this leads to many anomalous physical prop...

On the Surface Chemical Aspects of Very High Energy Density, Rechargeable Li–Sulfur Batteries

Li(metal)–sulfur (Li–S) systems are among the rechargeable batteries of the highest possible energy density due to the high capacity of both electrodes. The surface chemistry de...

Scale-Free Networks Are Ultrasmall

We study the diameter, or the mean distance between sites, in a scale-free network, having N sites and degree distribution p(k) proportional, variant k(-lambda), i.e., the proba...

Design of electrolyte solutions for Li and Li-ion batteries: a review

Physical Chemical Principles of Photovoltaic Conversion with Nanoparticulate, Mesoporous Dye-Sensitized Solar Cells

We review the status of the understanding of dye-sensitized solar cells (DSSC), emphasizing clear physical models with predictive power, and discuss them in terms of the chemica...

A local search approximation algorithm for k-means clustering

In k-means clustering we are given a set of n data points in d-dimensional space ℜd and an integer k, and the problem is to determine a set of k points in ℜd, called centers, to...

Crumpled Globule Model of the Three-Dimensional Structure of DNA

We argue that in order to maintain the biological function of DNA confined inside the cell nucleus, its spatial structure has to be unknotted, of the so-called "crumpled globule...
