Fine scale infectious disease modeling using satellite-derived data.

Innovative tools for modeling infectious agents are essential for better understanding disease spread given the inherent complexity of changing and interacting ecological, environmental, and demographic factors. We leveraged fine-scale satellite data on urban areas to build a road-connected geospatial network upon which to model disease spread. This model was tested by simulating the spread of the 2009 pandemic influenza in Rwanda and also used to determine the effects of vaccination regimens on outbreak spread and impact.

MorphoLex-FR: A derivational morphological database for 38,840 French words.

Studies on morphological processing in French, as in other languages, have shown disparate results. We argue that a critical and long-overlooked factor that could underlie these diverging results is the methodological differences in the calculation of morphological variables across studies. To address the need for a common morphological database, we present MorphoLex-FR, a sizeable and freely available database with 12 variables for prefixes, roots, and suffixes for the 38,840 words of the French Lexicon Project.

MorphoLex: A derivational morphological database for 70,000 English words.

Most of the new words a reader will find are morphologically complex. Also, theoretical models of language processing propose that morphology plays an important role in visual word processing. Nevertheless, studies on the subject show contradicting results that are difficult to reconcile.

The biological half-time of radioactive Cs in poikilothermic and homeothermic animals.

Literature data for the half-time of Cs in one-, two-, and three-compartment models have been collated and regressed to yield general descriptions of clearance for homeotherms (warm-blooded animals) and poikilotherms (cold-blooded animals) of different sizes. Cesium half-times increase with body weight and are longer in poikilotherms than in homeotherms. These trends and the values of the associated regression coefficients imply that Cs clearance is a function of metabolic rate.
