Microscopic arrays of oligonucleotides or cDNA containing up to several hundred thousand different sequences are starting to influence methodologies and paths to discovery in genomics. Gene polymorphisms and mutations can be found and gene expression measured with unprecedented speed and parallelism. The principles of this modern technology and some of the problems awaiting further study are di...

This paper examines a few of the numerous factors that may have led to increased youth turnout in the 2008 Election. First, theories of voter behavior and turnout are related to courting the youth vote. Several variables that are perceived to affect youth turnout such as party polarization, perceived candidate difference, voter registration, effective campaigning and mobilization, and use of th...

Grain refinement can make conventional metals several times stronger, but this comes at dramatic loss of ductility. Here we report a heterogeneous lamella structure in Ti produced by asymmetric rolling and partial recrystallization that can produce an unprecedented property combination: as strong as ultrafine-grained metal and at the same time as ductile as conventional coarse-grained metal. It...

The Energy Recovery LINAC (ERL) being developed at Cornell should be an excellent source for Inelastic X-ray Scattering (IXS) because it will permit long undulators to operate at high efficiency generating unprecedented spectral flux (photons/second/meV) and brilliance. We discuss several advantages of the ERL for IXS experimentation. q 2005 Elsevier Ltd. All rights reserved.

An intermolecular ring expansion reaction of an aryl epoxide with several dienes, acrylates, enynes or styrenes under iron catalysis, generated tetrahydrofuran derivatives in a highly chemo- and regioselective fashion. The process could be used in an unprecedented way for the one step synthesis of racemic calyxolane A and calyxolane B with acceptable diastereoselectivity.

The X-ray luminous RS CVn binary system HR 1099 has been observed on several occasions in the early phases of Chandra and XMM-Newton. A very hot (up to 40 MK) dominant coronal plasma has been identified from the high-resolution spectroscopic data; cooler plasma is seen down to about 3 MK. We recently obtained 100 ksec in Chandra's Guest Observer Program to study the corona of HR 1099 with the H...

The current enthusiam to measure fluctuations in the CMB power spectrum at angular scales between 0.1 and 1 is largely motivated by the expectation that CMB determinations of cosmological parameters will be of unprecedented precision. In such circumstances it is important to estimate what we can already say about the cosmological parameters. In two recent papers (Lineweaver et al. 1997a & 1997b...

We describe a new training methodology for generative adversarial networks. The key idea is to grow both the generator and discriminator progressively: starting from a low resolution, we add new layers that model increasingly fine details as training progresses. This both speeds the training up and greatly stabilizes it, allowing us to produce images of unprecedented quality, e.g., CELEBA image...
