Internal ribosome entry sites (IRESs) are powerful model systems to understand how the translation machinery can be manipulated by structured RNAs and for exploring inherent features of ribosome function. The intergenic region (IGR) IRESs from the Dicistroviridae family of viruses are structured RNAs that bind directly to the ribosome and initiate translation by co-opting the translation elonga...

The INTEGRAL satellite, during its regular scanning observations of the Galactic plane, has discovered several new X-ray sources emitting above 20 keV. The nature of the great majority of them is still unknown. Here we report on the likely low energy counterpart, observed with ASCA in 1994 and 1997, of one of these sources, IGR J16195–4945. The ASCA source is faint (F2−10keV∼10 −11 erg cm s), h...

IGR J16320 − 4751 was re–discovered by IBIS/ISGRI on board INTEGRAL in early February 2003 during the observation of the black hole candidate 4U1630 − 47 (PI Tomsick). This source, already observed by ASCA and BeppoSAX, belongs to the class of heavily absorbed objects (N H > 10 23 cm −2) that populate some arms of the Galaxy. Soon after the rediscovery by IBIS/ISGRI, the source was observed by ...

The INTEGRAL observatory has been (re-)discovering new X-ray sources since the beginning of nominal operations in early 2003. These sources include X-ray binaries, Active Galactic Nuclei, cataclysmic variables, etc. Amongst the X-ray binaries, the true nature of many of these sources has remained largely elusive, though they seem to make up a population of highly absorbed high-mass X-ray binari...

Reputation is a valuable asset in online social lives and it has drawn increased attention. How to evaluate user reputation in online rating systems is especially significant due to the existence of spamming attacks. To address this issue, so far, a variety of methods have been proposed, including network-based methods, quality-based methods and group-based ranking method. In this paper, we pro...

Translation initiation of the second ORF of insect dicistrovirus RNA depends on an internal ribosomal entry site (IRES) in its intergenic region (IGR) and is exceptional in using a codon other than AUG and in not using the canonical initiator methionine tRNA. Studies in vitro suggest that pseudoknot I (PKI) immediately preceding the initiation codon occupies the ribosomal P site and that an elo...

Triatoma virus (TrV) belongs to a new family of RNA viruses known as Dicistroviridae. Nucleotide sequence comparisons between different dicistroviruses allowed two putative internal ribosomal entry sites (IRESs) in the TrV RNA to be defined: the 5'UTR IRES of 548 nt and the intergenic region (IGR) IRES of 172 nt. Using monocistronic and bicistronic RNAs, it was shown that the TrV genome contain...

ABSTRACT Since its launch, the INTErnational Gamma-Ray Astrophysics Laboratory (INTEGRAL) satellite has discovered hundreds of X-ray sources, many which lack proper classification. This mission also led to discovery new categories high mass binaries (HMXB). We use spectra X-Shooter instrument at Very Large Telescope (VLT) European Southern Observatory (ESO) better understand nature 3 accreting ...

A total of 1177 Sthenoteuthis oualaniensis were randomly collected from the northwest Indian Ocean February between May 2019 and 2020 by lighting falling-net vessels. The age, growth, population structure S. studied based on statolith microstructure. results showed that range mantle length (ML) was 123–562 mm for females 88–273 males, body weight (BW) 78–6268 g 82–518 males in 2020, respectivel...
