The effect of atmospheric absorption of sunlight on the runaway greenhouse point

The longwave emission of planetary atmospheres that contain a condensable absorbing gas in the infrared (i.e., longwave), which is in equilibrium with its liquid phase at the surface, may exhibit an upper bound. Here we analyze the effect of the atmospheric absorption of sunlight on this radiation limit. We assume that the atmospheric absorption of infrared radiation is independent of wavelength except within the spectral width of the atmospheric window, where it is zero. The temperature profile in radiative equilibrium is obtained analytically as a function of the longwave optical thickness. For illustrative purposes, numerical values for the infrared atmospheric absorption (i.e., greenhouse effect) and the liquid vapor equilibrium curve of the condensable absorbing gas refer to water. Values for the atmospheric absorption of sunlight (i.e., antigreenhouse effect) take a wide range since our aim is to provide a qualitative view of their effects. We find that atmospheres with a transparent region in the infrared spectrum do not present an absolute upper bound on the infrared emission. This result may be also found in atmospheres opaque at all infrared wavelengths if the fraction of absorbed sunlight in the atmosphere increases with the longwave opacity

Iniciativa emprenedora i immigració: característiques diferenciadores i factors d'èxit

 L’emprenedoria és una de les àrees de recerca que han tingut un major creixement en les dècades recents. En aquest camp, l’anàlisi del comportament dels emprenedors immigrants ha estat reconeguda com un dels temes amb un important increment d’estudis relacionats. En aquests moments, el fenomen de la immigració és un dels processos socials més importants i amb una major repercussió en el continent europeu, i el fet que hi hagi més iniciatives emprenedores liderades per immigrants que per nadius fa que l’anàlisi i l’exploració d’aquest tema tinguin un atractiu especial. Malgrat tot, i encara que en els darrers anys el nombre d’estudis que pretenen donar una explicació a aquest fenomen ha incrementat, la majoria dels estudis l’han analitzat des d’un punt de vista qualitatiu i centrant-se en situacions regionals específiques i grups concrets, sense que se n’hagin pogut extreure conclusions generals sobre el comportament emprenedor immigrant. De manera que uns dels aspectes clau que un estudi en profunditat requereix són ressaltar aquells factors que contribueixen a distingir el comportament emprenedor immigrant del nadiu, així com aquells factors que podrien motivar l’èxit o el fracàs d’aquest tipus d’iniciatives i com aquests factors condicionarien la resta del teixit empresarial. En aquest context, el principal objectiu d’aquest projecte consisteix en l’anàlisi de les característiques distintives del procés emprenedor dels immigrants. Es pretén abordar aquest objectiu desenvolupant diferents metodologies i combinant diferents fonts d’informació que permetin captar la situació i assolir una comprensió més rica del fenomen estudiat. Els principals resultats obtinguts ens han portat a entendre aspectes que afavoreixen l’emprenedoria immigrant, tals com una menor aversió al risc i un major control percebut. A més, s’han posat de manifest algunes barreres legals amb les que s’han d’enfrontar els emprenedors immigrants a Catalunya.

General practitioners can evaluate the material, social and health dimensions of patient social status

OBJECTIVE: To identify which physician and patient characteristics are associated with physicians' estimation of their patient social status.DESIGN: Cross-sectional ulticentric survey. SETTING: Fourty-seven primary care private offices in Western Switzerland. PARTICIPANTS: Random sample of 2030 patients ≥ 16, who encountered a general practitioner (GP) between September 2010 and February 2011. MAIN MEASURES: PRIMARY OUTCOME: patient social status perceived by GPs, using the MacArthur Scale of Subjective Social Status, ranging from the bottom (0) to the top (10) of the social scale.Secondary outcome: Difference between GP's evaluation and patient's own evaluation of their social status. Potential patient correlates: material and social deprivation using the DiPCare-Q, health status using the EQ-5D, sources of income, and level of education. GP characteristics: opinion regarding patients' deprivation and its influence on health and care. RESULTS: To evaluate patient social status, GPs considered the material, social, and health aspects of deprivation, along with education level, and amount and type of income. GPs declaring a frequent reflexive consideration of their own prejudice towards deprived patients, gave a higher estimation of patients' social status (+1.0, p = 0.002). Choosing a less costly treatment for deprived patients was associated with a lower estimation (-0.7, p = 0.002). GP's evaluation of patient social status was 0.5 point higher than the patient's own estimate (p<0.0001). CONCLUSIONS: GPs can perceive the various dimensions of patient social status, although heterogeneously, according partly to their own characteristics. Compared to patients' own evaluation, GPs overestimate patient social status.

Le point sur le traitement de l'hépatite C chronique [An update on the management of chronic hepatitis C]

Treatment of chronic hepatitis C with pegylated interferon-a and ribavirin is now adapted individually based on the virological response on treatment. This approach should improve the tolerability while maintaining or even improving in some patients the efficacy of antiviral therapy. Several new antiviral drugs are currently being evaluated in advanced clinical trials, with very promising results. These new drugs should greatly broaden treatment options for chronic hepatitis C in the near future.

Auditory-visual multisensory interactions in humans: timing, topography, directionality, and sources.

Current models of brain organization include multisensory interactions at early processing stages and within low-level, including primary, cortices. Embracing this model with regard to auditory-visual (AV) interactions in humans remains problematic. Controversy surrounds the application of an additive model to the analysis of event-related potentials (ERPs), and conventional ERP analysis methods have yielded discordant latencies of effects and permitted limited neurophysiologic interpretability. While hemodynamic imaging and transcranial magnetic stimulation studies provide general support for the above model, the precise timing, superadditive/subadditive directionality, topographic stability, and sources remain unresolved. We recorded ERPs in humans to attended, but task-irrelevant stimuli that did not require an overt motor response, thereby circumventing paradigmatic caveats. We applied novel ERP signal analysis methods to provide details concerning the likely bases of AV interactions. First, nonlinear interactions occur at 60-95 ms after stimulus and are the consequence of topographic, rather than pure strength, modulations in the ERP. AV stimuli engage distinct configurations of intracranial generators, rather than simply modulating the amplitude of unisensory responses. Second, source estimations (and statistical analyses thereof) identified primary visual, primary auditory, and posterior superior temporal regions as mediating these effects. Finally, scalar values of current densities in all of these regions exhibited functionally coupled, subadditive nonlinear effects, a pattern increasingly consistent with the mounting evidence in nonhuman primates. In these ways, we demonstrate how neurophysiologic bases of multisensory interactions can be noninvasively identified in humans, allowing for a synthesis across imaging methods on the one hand and species on the other.

Bilinear models for spatio-temporal point distribution analysis: application to extrapolation of left ventricular, biventricular and whole heart cardiac dynamics

In this work we describe the usage of bilinear statistical models as a means of factoring the shape variability into two components attributed to inter-subject variation and to the intrinsic dynamics of the human heart. We show that it is feasible to reconstruct the shape of the heart at discrete points in the cardiac cycle. Provided we are given a small number of shape instances representing the same heart atdifferent points in the same cycle, we can use the bilinearmodel to establish this. Using a temporal and a spatial alignment step in the preprocessing of the shapes, around half of the reconstruction errors were on the order of the axial image resolution of 2 mm, and over 90% was within 3.5 mm. From this, weconclude that the dynamics were indeed separated from theinter-subject variability in our dataset.
