We present broad-band (2 keV to 2 MeV) x-ray spectra of GRO J1655–40, a luminous X-ray transient and occasional source of relativistic radio jets, obtained with the Rossi X-Ray Timing Explorer (RXTE) and the Oriented Scintillation Spectrometer Experiment (OSSE). In one observation, the luminosity is found to be 18% of the Eddington limit, which is one of the highest luminosities ever observed f...

Carbon dioxide (CO2) adsorption on decorated graphene (GR) sheets with transition metals (TMs) including iron, nickel and zinc was investigated for removing this hazardous gas from the environment. TM-doped GR results in higher activity toward detecting than pristine nanosheets. TM embedding restrains hydrogen evolution C sites, leaving more available sites a CO2 decrease. The Langmuir model ON...

La investigación se llevó a cabo en un huerto citrícola de naranja Citrus sinensis L. Var temprana Marrs. Utilizando diseño bloques completos al azar con cuatro tratamientos y repeticiones, análisis estadístico Tukey 0.5 %, comparación medias. Los fueron (T1) el complejo hormonal Biozyme TF utilizando 25 ml como recomendación del producto 20 L agua, (T2) utilizó fertilizante zinc (25 ml) (T3) g...

Previously we claimed that Black Hole X-ray Novae (BHXN) in quiescence are much less luminous than equivalent Neutron Star X-ray Novae (NSXN). This claim was based on the quiescent detection of a single short period BHXN (A0620–00, Porb=7.8 hrs) and two longer period BHXN (GRO J1655–40, Porb=62.9 hrs; V404 Cyg, Porb=155.3 hrs), along with sensitive upper limits. We announce the detection of two...

In eukaryotes, the ability of DNA-binding proteins to act as transcriptional repressors often requires that they recruit accessory proteins, known as corepressors, which provide the activity responsible for silencing transcription. Several of these factors have been identified, including the Groucho (Gro) and Atrophin (Atro) proteins in Drosophila. Here we demonstrate strong genetic interaction...

A full length cDNA clone of the platelet-derived growth factor-inducible KC gene has been isolated, sequenced, and expressed in COS cells. Both sequence analysis and expression studies indicate that KC encodes a secretory protein. Sequence analysis shows that, furthermore, the protein encoded by KC belongs to a growing superfamily of inducible proteins with a common ancestral linkage to the pla...

The repetitive X-ray bursts from the accretion-powered pulsar GRO J1744228 show similarities to the type II X-ray bursts from the Rapid Burster. Several authors (notably, Lewin et al.) have suggested that the bursts from GRO J1744228 are type II bursts (which arise from the sudden release of gravitational potential energy). In this paper, we present another similarity between these sources. Ros...

Ambient particulate matter (PM) is known to induce inflammation in the respiratory tract of exposed subjects. The aim of the present study was to detect, in bronchial epithelial cells, candidate inflammatory genes exhibiting transcriptional modifications following urban PM2.5 exposure. Paris urban PM2.5 sampled either at a curbside or a background station in winter and in summer was tested in c...

Global run-on sequencing (GRO-seq) is a recent addition to the series of high-throughput sequencing methods that enables new insights into transcriptional dynamics within a cell. However, GRO-sequencing presents new algorithmic challenges, as existing analysis platforms for ChIP-seq and RNA-seq do not address the unique problem of identifying transcriptional units de novo from short reads locat...

Gentle Remediation Options (GRO) are remediation measures involving plants, fungi, bacteria, and soil amendments that can be applied to manage risks at contaminated sites. Several studies decision-support tools promote the wider range of benefits provided by GRO, but there is still skepticism regarding GRO implementation. Key issues need better communicated various risk mitigation mechanisms, r...
