Sus integrantes se embarcan en la lectura de importantes textos literarios pertenecientes tanto a la tradición nacional y la propia lengua como a tradiciones de otros países y de otros idiomas. Esas lecturas, que son compartidas, van enriqueciendo la vida gracias a las originales historias, al dominio lingüístico y a la complejidad de las visiones puestas en juego en cada obra. Es así como todos los integrantes van madurando sus particulares concepciones del mundo y van aprendiendo a educar su íntima búsqueda de la belleza. Búsqueda que va fortaleciéndose a medida que cada tallerista va encontrándose a sí mismo a través de esos juegos de espejos que son los libros. Suele suceder, entonces, que la propia voz comience a tomar forma y que demande expresarse por unos cauces que les sean originarios. Es cuando surgen las obras, las florescencias, las creaciones que ayudan a forjar para uno mismo un lugar habitable en el mundo. Esta antología es precisamente la primera muestra pública de las voces emergentes de los miembros del Taller Literario Mariano Lebrón Saviñón, uno de los órganos culturales de la Universidad APEC. La componen textos llenos de vida y pasión, de una mirada maravillada a esta existencia convulsa, que puede a veces ser turbulenta, pero que siempre es hermosa. Son textos para olvidarse de sí y perderse en la inquietante lumbre que ofrecen
The Cockroach Genus Calolampra of Australia With Descriptions of New Species (Blaberidae)
Spasmolytic Effects Of Kauranoid And Ester Of Linear Alkaloid From The Aerial Part Of Croton Borarium (Euphorbiaceae) Endemic In South Part Of Madagascar
The aerial part of the plant known under the vernacular name Somorombohitse (Malagasy name) and scientifically named Croton Borarium (Euphorbiaceae) endemic in the South part of Madagascar, is used by the local communities to treat asthma and hypertension. The biologic test result riddling of the isolated trachea of guinea pig stimulated by the acetylcholine in 210-2M showed antiasthmatic activity with the CE50= 0.85±0.001µg/ml (n=6). Effet concentration of carbachol from 10-9M to 10-3M have been realized in absence and in presence of the hydro-ethanolic extract of Cr. Borarium to 0.1mg/ml, verapamil to 10µM and atropine to 10nM. The relaxing activity of hydro-ethanolic extract from 0.1 to 3 mg/ml has been executed on the isolated aorta and jejunum of rabbit stimulated with the KCl to 50nM. White the using of the extract technic by partitioned liquid-liquid to permitted localizing the active fraction (Hex/DCM: 3/1) with CI50= 0.275±0.003µg/ml (n=6).The bioassay-guided fractionation of the active fraction using repeated silica gel column chromatography resulted in the isolation of two pure compounds active as evidenced by analytical TLC and HPLC analysis. The elucidation of pharmacologic mechanism of these active principles has showed that, to first and active principle bring into play the calcic movement through the cellular membrane of vascular and polished muscle and the second is the by way of NO intermediate. Their chemical structures of two pure compounds were determined by 1D and 2D NMR spectroscopy and spectroscopy High-resolution MS.

XAI & I: Self-explanatory AI facilitating mutual understanding between AI and human experts
Traditionally, explainable artificial intelligence seeks to provide explanation and interpretability of high-performing black-box models such as deep neural networks. Interpretation of such models remains difficult, because of their high complexity. An alternative method is to instead force a deep-neural network to use human-intelligible features as the basis for its decisions. We tested this approach using the natural category domain of rock types. We compared the performance of a black-box implementation of transfer-learning using Resnet50 to that of a network first trained to predict expert-identified features and then forced to use these features to categorise rock images. The performance of this feature-constrained network was virtually identical to that of the unconstrained network. Further, a partially constrained network forced to condense down to a small number of features that was not trained with expert features did not result in these abstracted features being intelligible; nevertheless, an affine transformation of these features could be found that aligned well with expert-intelligible features. These findings show that making an AI intrinsically intelligible need not be at the cost of performance
Novos registros de Phoetalia pallida (Brunner, 1865) para o Brasil e considerações sobre a variação cromática da espécie (Blattaria, Blaberidae, Blaberinae)
Cockroaches Probably Cleaned Up after Dinosaurs
Dinosaurs undoubtedly produced huge quantities of excrements. But who cleaned up after them? Dung beetles and flies with rapid development were rare during most of the Mesozoic. Candidates for these duties are extinct cockroaches (Blattulidae), whose temporal range is associated with herbivorous dinosaurs. An opportunity to test this hypothesis arises from coprolites to some extent extruded from an immature cockroach preserved in the amber of Lebanon, studied using synchrotron X-ray microtomography. 1.06% of their volume is filled by particles of wood with smooth edges, in which size distribution directly supports their external pre-digestion. Because fungal pre-processing can be excluded based on the presence of large particles (combined with small total amount of wood) and absence of damages on wood, the likely source of wood are herbivore feces. Smaller particles were broken down biochemically in the cockroach hind gut, which indicates that the recent lignin-decomposing termite and cockroach endosymbionts might have been transferred to the cockroach gut upon feeding on dinosaur feces
