El Llibre dels ocells de caça, o Flors de les receptes medicinals per a ocells de caça

Resum: Edició d’un dels textos de falconeria medievals conservats en català, interessant per l’extensió i per la qualitat de la redacció, amb un vocabulari ric, variat i especialitzat. Està format per la unió de dos tractats diferents i apareix recollit en un extens volum miscel·lani copiat en el segle XV en el qual es recullen, també, altres tractats, de cosmètica femenina, de cuina, etc. Tot i que les fonts del Llibre dels ocells de caça, o Flors de les receptes medicinals per a ocells de caça semblen molt abundants, anotem ací l’edició amb la que permet un acarament més evident per la proximitat entre el text llatí i el català, ja que n’és la font directa; es tracta del De falconibus de sant Albert el Gran o sant Albert Magne, del qual hi ha una versió parcial entre els folis 122v a 138v del manuscrit. Paraules clau: edició, tractats de falconeria, edat mitjana, Albert el Gran. Abstract: This work focuses in the edition of a medieval falconry text written in Catalan. This is an interesting text because of its length and the quality of its language, with a rich, varied, and specialized vocabulary. It joins two different treatises, copied into a larger 15th-century miscellaneous manuscript, in which other treatises are also collected, such as one on women’s cosmetics, another on cooking, etc. Although the sources of the Llibre dels ocells de caça, o Flors de les receptes medicinals per a ocells de caça seem very abundant, we annotate the edition with the source allowing a more direct comparison because of the proximity between the Latin and Catalan text; namely, the De falconibus by St. Albert the Great, of which there is a partial version in folios 122v to 138v of the manuscript. Key words: text edition, treatise, falconry, Middle Ages, Albert the Great.

Identifying Fraudulent Behaviors in Healthcare Claims Using Random Forest Classifier With SMOTEchnique

Detecting fraudulent and abusive cases in healthcare is one of the most challenging problems for data mining studies. Existing studies have a lack of real data for analysis and focus on a very partial version of the problem by covering only a specific actor, healthcare service, or disease. In this article, the proposed strategy identifies fraudulent behaviors in Medicare claims data using several predictors as model inputs. The methodology involves preprocessing and model development phases. At the initial phase, the feature mining is done by estimating their feature importance score. The labeling of instances by using the classification rules to the whole dataset. Thus, a transformed dataset is obtained by the model. In the development phase, the RF with SMOTE is applied against the training and testing data. Specifically, SMOTE adapted to balance data and sorts misclassified instances and finds the interesting instances. The results of the proposed model improvises the classifier performance RF with SMOTE when contrast with RF method.

Équivalence motivique des groupes algébriques semisimples

We prove that the standard motives of a semisimple algebraic group$G$with coefficients in a field of order$p$are determined by the upper motives of the group $G$. As a consequence of this result, we obtain a partial version of the motivic rigidity conjecture of special linear groups. The result is then used to construct the higher indexes which characterize the motivic equivalence of semisimple algebraic groups. The criteria of motivic equivalence derived from the expressions of these indexes produce a dictionary between motives, algebraic structures and the birational geometry of twisted flag varieties. This correspondence is then described for special linear groups and orthogonal groups (the criteria associated with other groups being obtained in De Clercq and Garibaldi [Tits$p$-indexes of semisimple algebraic groups, J. Lond. Math. Soc. (2)95(2017) 567–585]). The proofs rely on the Levi-type motivic decompositions of isotropic twisted flag varieties due to Chernousov, Gille and Merkurjev, and on the notion of pondered field extensions.
