The unique topographic,climatic,and latitudinal heterogeneity of Mesoamerica is crucial to understanding the evolutionary emergence of one of the richest cultural and biological regions in the planet and its impact on food *** divided between two regions of large biodiversity-lowland tropical or coastal zones and temperate or subtropical highlands sculpted by parallel sierras and their central plateau-the Mexican territory harbors more than 2000 endemic monocotyledonous species,including several hundred grasses(Poaceae),particularly those belonging to the genus Zea,composed of maize(Zea mays ***)and its wild relatives,collectively referred as teosintes.

In the context of Semiosic Translation,two elements are essential for a translation to emerge:the body–brain–context interface(extended mind)and the sign systems making up a translation *** this paper,I explain how a renewed view of the body as a Bayesian-heuristic Semiotic Prior helps to understand in a more holistic manner the motivations and agentive character of translation,defined herein as a phenomenological grasp of the *** to the present proposal is the idea that bodily self-stabilization(homeostasis)and brain-driven correction(allostasis)provide translator-agents with maps of action upon the world that are semiotic in *** this occurs thanks to information weighing(Bayesian)and cue-driven(heuristic)types of inference whereby exteroceptive(exogenous)and interoceptive(inner-body)signals converge to create a sense of bodily awareness responsible for the construction of the symbolic persona(the translator-agent).

In this work,several ceria-zirconia based catalysts with very lo w(and equimolar) metal contents were prepared,characterised and tested for the CO oxidatio n reaction(under lean and stoichiometric conditions),trying to emulate those conditions found in a diesel oxidation catalyst(DOC) system from a diesel engine and those encountered under gasoline exhaust(λ=1).The metals chosen are Cu,Co,Ag and Pt(as a reliable benchmark).The results reveal enormous differences among reducibility and catalytic activity despite quite similar structural and textural properties of the catalysts,showing differences among dispersion(Ag-catalyst seems to present a low level of dispersion).This catalyst seems to be characterised,as well,by a strong electronic interaction between Ce and Ag centres which is suggested to yield an improved reducibility under H_(2)-TPR ***,the order in catalytic activity(Cu>Ag>Co≈Pt>>support) seems not to follow the order found in reducibility and the Cu-catalyst seems to be the most active independently on the reaction conditions,yielding nearly overlapped CO oxidation catalytic *** restingly,a stro ng correlation between the catalytic activity under the two conditions tested and the OSC values of the Ce_(0.8)Zr_(0.2)O_(2)-supported metal catalysts is ***,OSC parameter measured at 150℃ can be used as a relevant descriptor to evaluate the CO oxidation activity at low and medium conversions for the investigated catalysts,much better than the H_(2)-TPR measurements.

Relevance of liver fibrosis amongst diabetic patients with metabolic-dysfunction associated steatotic liver disease(MASLD)and knowledge gaps Insulin resistance is paramount in the crosstalk between intrahepatic and extrahepatic pathophysiological mechanisms leading to MASLD(1),hence gaining special relevance in patients diagnosed with type 2 diabetes(T2D).MASLD is the term that was recently endorsed by an international multidisciplinary consensus panel to replace non-alcoholic fatty liver disease[as non-alcoholic steatohepatitis(NASH)was replaced by metabolic dysfunction-associated steatohepatitis(MASH)](2).

The aim of this work is to predict,for the first time,the high temperature flow stress dependency with the grain size and the underlaid deformation mechanism using two machine learning models,random forest(RF)and artificial neural network(ANN).With that purpose,a ZK30 magnesium alloy was friction stir processed(FSP)using three different severe conditions to obtain fine grain microstructures(with average grain sizes between 2 and 3μm)prone to extensive superplastic *** three friction stir processed samples clearly deformed by grain boundary sliding(GBS)deformation mechanism at high *** maximum elongations to failure,well over 400% at high strain rate of 10^(-2)s^(-1),were reached at 400℃ in the material with coarsest grain size of 2.8μm,and at 300℃ for the finest grain size of 2μ***,the superplastic response decreased at 350℃ and 400℃ due to thermal instabilities and grain coarsening,which makes it difficult to assess the operative deformation mechanism at such *** work highlights that the machine learning models considered,especially the ANN model with higher accuracy in predicting flow stress values,allow determining adequately the superplastic creep behavior including other possible grain size scenarios.
