The possible associations between the microquasars LS 5039 and LS I +61 303 and the EGRET sources 3EG J1824−1514 and 3EG J0241+6103 suggest that microquasars could also be sources of high-energy γ-rays. In this work, we present a detailed numerical inverse Compton (IC) model, based on a microquasar scenario, that reproduces the high-energy γ-ray spectra and variability observed by EGRET for the...
The possible association between the microquasar LS 5039 and the EGRET source 3EG J1824−1514 suggests that microquasars could also be sources of high-energy γ-rays. In this paper, we explore, with a detailed numerical model, if this system can produce the emission detected by EGRET (>100 MeV) through inverse Compton (IC) scattering. Our numerical approach considers a population of relativistic ...
En el trabajo se repasan los recientes hallazgos de nuevas ediciones, o ejemplares no documentados, la Tragicomedia Calisto y Melibea. También da a conocer un curioso testimonio manipulado, conservado en Biblioteca estatal Ulm, que transmite, junto dos primeros folios Valencia (Juan Jofré, 1514), una edición desconocida hasta fecha incorpora éxplicit rimado con particular con-trahechura «Sevill...
We have discovered a Narrow-Line Seyfert 1 (NLS1) galaxy and identified it with an ultrasoft X-ray source (RX 215319-1514) detected with ROSAT . We present its X-ray and optical spectral characteristics. Its redshift is found to be 0.0778±0.0002. Its optical spectrum shows fairly strong Fe II emission lines, and its X-ray spectrum has an extremely steep power-law index of Γ ≥4, making it an ext...
Thrombin is clearly a key trigger of thrombosis, the proximal cause of most morbidity and mortality in atherosclerotic cardiovascular disease. Might thrombin also contribute to longer-term, structural changes in the arterial wall that promote narrowing and clotting? A study in this issue of the JCI argues that it can. Aihara et al. report that haploinsufficiency of heparin cofactor II, a glycos...
We study the proximity coherence in a mesoscopic normal-metal film in contact with a superconductor. Accounting for a repulsive interaction between the electrons in the normal metal, we find an enhanced local density of states close to the normal-metal–superconductor interface. The sharp peak in the density is pinned to the Fermi energy and leads to spontaneous paramagnetic interface currents. ...
This paper updates our 2003 study on the effect of intellectual disability (ID) on mortality in persons with no significant physical disability. As previously, we used the California Department of Developmental Services database to compute mortality rates by age, sex, and severity of ID. There were 64,207 subjects age 5 and older, who contributed 386,000 person-years of follow-up and 1514 death...
We consider the approximate minimization of a given polynomial on the standard simplex, obtained by taking the minimum value over all rational grid points with given denominator r ∈ N. It was shown in [De Klerk, E., Laurent, M., Sun, Z.: An error analysis for polynomial optimization over the simplex based on the multivariate hypergeometric distribution. SIAM J. Optim. 25(3) 1498–1514 (2015)] th...
