Space View Starting on OCK 12581, the normal MGS mapping orientation was rotated 16 degrees as a fuel saving measure. As a result, TES could no longer use the -90 pointing angle for the space view used for calibration because a portion of Mars could find its way into the field of view (FOV). With this spacecraft orientation change, the space view was switched to a +74 pointing angle, which woul...

Transposable elements (TEs) are DNA elements found in the genomes of various organisms. TEs have been highly conserved during evolution, suggesting that they confer advantageous effects to their hosts. However, due to their ability to transpose into virtually any locus, TEs have the ability to generate deleterious mutations in the host genome. In response, a variety of different mechanisms have...

Transposable elements (transposons or TEs), which are capable of transferring segments of DNA (or of being transferred) from one site to another within a genome, are abundant in eukaryotic genomes. The highly repetitive, largely noncoding sequence that is prevalent in eukaryotic genomes consists largely of TEs. TEs make up nearly half of the human genome (Lander et al., 2001) and an estimated 5...

Transcranial electrical stimulation (tES), including transcranial direct and alternating current stimulation (tDCS, tACS) are non-invasive brain stimulation techniques increasingly used for modulation of central nervous system excitability in humans. Here we address methodological issues required for tES application. This review covers technical aspects of tES, as well as applications like expl...

The lower bank of the superior temporal sulcus (TEs), part of the inferior temporal cortex, contains neurons selective for disparity-defined three-dimensional (3-D) shape. The large majority of these TEs neurons respond to the spatial variation of disparity, i.e., are higher-order disparity selective. To determine whether curved boundaries or curved surfaces by themselves are sufficient to elic...

OBJECTIVE There is evidence to suggest that low concentrations of testosterone are associated with an increased risk of cardiovascular disease in men. The aim of this study was to evaluate the relationship between serum testosterone concentration and carotid atherosclerosis as well as major cardiovascular risk factors in men with type 2 diabetes. RESEARCH DESIGN AND METHODS Serum free and tot...

Approximately 45% of the human genome is comprised of transposable elements (TEs). Results from the Human Genome Project have emphasized the biological importance of TEs. Many studies have revealed that TEs are not simply "junk" DNA, but rather, they play various roles in processes, including genome evolution, gene expression regulation, genetic instability, and cancer disposition. The effects ...

We use the Tropospheric Emission Spectrometer (TES) aboard the NASA Aura satellite to determine the concentrations of the trace gases ammonia (NH3) and formic acid (HCOOH) within boreal biomass burning plumes, and present the first detection of peroxy acetyl nitrate (PAN) and ethylene (C2H4) by TES. We focus on two fresh Canadian plumes observed by TES in the summer of 2008 as part of the Arcti...

In flowering plants, male meiosis occurs in the microsporocyte to produce four microspores, each of which develops into a pollen grain. Here we describe four mutant alleles of TETRASPORE (TES), a gene essential for microsporocyte cytokinesis in Arabidopsis thaliana. Following failure of male meiotic cytokinesis in tes mutants, all four microspore nuclei remain within the same cytoplasm, with so...

Although numerous studies have been performed using transcranial electrical stimulation (tES), our understanding of tES-induced effects on neural activity remains limited, especially regarding the effects on neural networks. The use of an approach, such as electroencephalography (EEG) in combination with tES, could allow for a more detailed understanding of the neural mechanisms involved in the...
