Two recent studies show that a neural globin tunes oxygen responses in the nematode Caenorhabditis elegans. Analysis of wild C. elegans strains suggests that the commonly used Bristol strain may have adapted to life in the laboratory.

Studies of elemental abundances in stars belonging to the thin and the thick disk of our Galaxy are reviewed. Edvardsson et al. (1993) found strong evidence of [α/Fe] variations among F and G main sequence stars with the same [Fe/H] and interpreted these differences as due to radial gradients in the star formation rate in the Galactic disk. Several recent studies suggest, however, that the diff...

We introduce and study the behavior of a tethered membrane of non-zero thickness embedded in three dimensions subject to an effective self-attraction induced by hydrophobicity arising from the tendency to minimize the area exposed to a solvent. The phase behavior and the nature of the folded conformations are found to be quite distinct in the small and large solvent size regimes. We demonstrate...

I briefly review the growing evidence that thick stellar disks surround most edgeon disk galaxies. Recent studies show that these extragalactic thick disks have old ages, low metallicities, long scale lengths, and moderately flattened axial ratios, much like the thick disk of the Milky Way. However, the properties of thick disks change systematically with the mass of the galaxy. The thick disks...

We have performed an abundance analysis for Fand Gdwarfs of the Galactic thick disk component. A sample of 176 nearby (d ≤ 150 pc) thick disk candidate stars was chosen from the Hipparcos catalogue and subjected to a high-resolution spectroscopic analysis. Using accurate radial velocities combined with Hipparcos astrometry, kinematics (U, V, and W ) and Galactic orbital parameters were computed...

The origins, cross-disciplinary evolution, and definition of “thick description” are reviewed. Despite its frequent use in the qualitative literature, the concept of “thick description” is often confusing to researchers at all levels. The roots of this confusion are explored and examples of “thick description” are provided. The article closes with guidelines for presenting “thick description” i...

We examined 5d thick brane worlds constructed by a real scalar field. The solutions are obtained in terms of a simple form of smooth warp factor. For the case of dS brane, we found a disease of the solutions. For example, it is impossible to construct thick-brane worlds with our simple smoothing. This result is independent of supersymmetry or other symmetries. [email protected] yahiro@s...

We distinguish between two categories of belief — thin belief and thick belief — and provide evidence that they approximate genuinely distinct categories within folk psychology. We use the distinction to make informative predictions about how laypeople view the relationship between knowledge and belief. More specifcally, we show that if the distinction is genuine, then we can make sense of othe...

A sensor node is generally small in physical size (typically a few cm or smaller) and consist of a sensor, a transceiver, and supporting electronics. They are connected as a wireless network and are sometimes isolated and embedded in structures, which are not easily accessible. The lifespan of the sensor node is critically dependent upon the power source it contains. Instead of using a limited ...

We relate the dynamic semantics (games, dealing with interactions) and the static semantics (dealing with results of interactions) of linear logic with polarities, in the spirit of Timeless Games [1]. The polarized game semantics is full and faithfull for polarized proof-nets [2]. We detail the correspondence between cut free proof-nets and innocent strategies, in a framework related to abstrac...
