Distribuição e notas de história natural do lagarto peruano Proctoporus laudahnae (Squamata: Gymnophthalmidae)

Desde su descripción, poco se conoce a cerca de la lagartija Proctoporus laudahnae. Basados en seis individuos colectados recientemente en la localidad Achupampa, en las laderas orientales andinas del centro de Perú, presentamos aquí información novedosa sobre su distribución geográfica, coloración en vida, variación en la escamación e historia naturalDesde sua descrição, há poucas informações sobre o lagarto Proctoporus laudahnae. Com base em seis indivíduos coletados recentemente na localidade de Achupampa, nas encostas andinas orientais do centro do Perú, apresentamos aqui informações inéditas sobre sua distribuição geográfica, coloração em vida, variação na escamação e história naturalLittle has been learned about the lizard Proctoporus laudahnae since its description. Based on six specimens collected recently from Achupampa, on the eastern Andean slopes of central Peru, we present data about its geographic distribution, coloration in life, pholidosis variation, and natural histor

Spin effects in strong-field laser-electron interactions

The electron spin degree of freedom can play a significant role in relativistic scattering processes involving intense laser fields. In this contribution we discuss the influence of the electron spin on (i) Kapitza-Dirac scattering in an x-ray laser field of high intensity, (ii) photo-induced electron-positron pair production in a strong laser wave and (iii) multiphoton electron-positron pair production on an atomic nucleus. We show that in all cases under consideration the electron spin can have a characteristic impact on the process properties and their total probabilities. To this end, spin-resolved calculations based on the Dirac equation in the presence of an intense laser field are performed. The predictions from Dirac theory are also compared with the corresponding results from the Klein-Gordon equation.Comment: 9 pages, 6 figure

Datasets for transcriptomics, q-proteomics and phenotype microarrays of polyphosphate metabolism mutants from Escherichia coli

Indexación: Scopus.Author acknowledges Fondecyt Grants 1120209, 1121170 and Anillo ACT-1107Here, we provide the dataset associated with our research article on the polyphosphate metabolism entitled, “Multi-level evaluation of Escherichia coli polyphosphate related mutants using global transcriptomic, proteomic and phenomic analyses”. By integrating different omics levels (transcriptome, proteome and phenome), we were able to study Escherichia coli polyphosphate mutant strains (Δppk1, Δppx, and Δppk1-ppx). We have compiled here all datasets from DNA microarrys, q-proteomic (Isotope-Coded Protein Labeling, ICPL) and phenomic (Phenotype microarray) raw data we have obtained in all polyP metabolism mutants.http://www.sciencedirect.com/science/article/pii/S2352340917300860?via%3Dihu
