The human brain processes a wide variety of inputs and does so either consciously or subconsciously. According to the Global Workspace theory, conscious processing involves broadcasting of information to several regions of the brain and subconscious processing involves more localized processing. This theoretical paper aims to expand on some of the aspects of the Global Workspace theory: how the...

Extending axons are guided in part by diffusible chemoattractants that lure them to their targets and by diffusible chemorepellents that keep them away from nontarget regions. Floor plate cells at the ventral midline of the neural tube express a diffusible chemoattractant, netrin-1, that attracts a group of ventrally directed axons. Here we report that floor plate cells also have a long-range r...

Rob Albritton’s Let Them Eat Junk: How Capitalism Creates Hunger and Obesity (2009), published by Arbeiter Ring Press in Canada, and Pluto Press in the UK, offers a welcome and urgently needed analysis of “how the profit fixation of capital has led us deeply into a dangerously unsustainable system of food provision, a system that totally fails when it comes to distributive justice and to human ...

atopic dermatitis (ad) is one of the most common infantile diseases. immunological dysfunctions in ad patients may predispose them to infections. the aim of this study was to evaluate the relationship between infantile ad and urinary tract infection (uti). in this cross sectional study, we enrolled 57 patients with ad aged 1 to 24 months that referred to dermatology clinic, and 57 healthy contr...

Context. Investigation of transneptunian objects, including Pluto and its satellites, by stellar occultations. Aims. Derive precise, astrometric predictions for stellar occultations by Pluto and its satellites Charon, Hydra and Nix for 2008–2015. Construct an astrometric star catalog in the UCAC2 system covering Plutos sky path. Methods. We have carried out in 2007 an observational program at t...

Walnut Street, Suite 400, Boulder, CO 80302 [email protected], Earth Sciences Department, University of California; Santa Cruz, CA 95064. Introduction: The Pluto-Charon system shares key commonalities with the Earth-Moon system, e.g., its large satellite-to-planet mass ratio, high system angular momentum and a potentially reduced satellite density relative to that of the planet. In both ca...

Observations of the 1.4- to 2.4-micrometer spectrum of Pluto reveal absorptions of carbon monoxide and nitrogen ices and confirm the presence of solid methane. Frozen nitrogen is more abundant than the other two ices by a factor of about 50; gaseous nitrogen must therefore be the major atmospheric constituent. The absence of carbon dioxide absorptions is one of several differences between the s...

The PLuTo scheduling algorithm is a well-known algorithm for automatic scheduling in the polyhedral compilation model. It seeks linearly independent affine partition mappings for each statement of a Static Control Program (SCoP), such that total communication is minimized. In this paper we show that this algorithm can be sensitive to the layout of the global constraint matrix thus resulting to ...
