In the European context, new legislation to avoid mineral contamination and ban on antibiotics as growth promoters has led definition of objectives in respect nitrogen supply. The present study summarizes state nutrition rabbits reviews role protein amino acids rabbit health value sources based true ileal digestibility (TID) for future recommendations. main microbial are ammonia, urea (endogenous dietary). surplus flow caecum increases mortality rates during fattening by favouring potential...
GRBs generate an afterglow emission that can be detected from radio to X-rays during days, or even weeks after the initial explosion. The peak of this crosses mm/submm range first hours making their study in crucial for constraining models. Observations have been limited until now due low sensitivity observatories range. We present observations 10 GRB afterglows obtained APEX and SMA, as well detection a with ALMA, put them into context all published spectral will covered by ALMA. catalogue...
Context. GRB afterglow spectra are sensitive probes of interstellar matter along the line-of-sight in their host galaxies, as well intervening galaxies. The rapid fading GRBs makes it very difficult to obtain sufficient resolution and S/N allow for these kinds studies.
The possible existence of a continuum encompassing the diversity explosive stellar deaths,ranging from ordinary SNe to relativistic hypernovae associated with long duration GRBs, is under intense debate. In this context, SN2008D XT080109 could represent paradigmatic case, since it might exemplify potential borderline event. main aim infer geometric information through evolution its linear optical polarization. We also report polarization SN2007uy, and discuss properties host ISM towards XT....
Aims.We have performed optical polarimetric observations of the SN 2006aj associated to X-ray flash (XRF) February 18, 2006, XRF 060218 that provide information on its expansion geometry.
Context.The prompt emission of gamma-ray bursts is mostly thought to be produced in internal shocks relativistic shells emitted by the progenitor at different times, whereas late multi-band afterglow interpreted as synchrotron electrons swept up fireball expanding through surrounding interstellar medium. The short timescale variability observed flares superimposed on X-ray/optical several bursts, recently made possible Swift, has been evidence for prolonged activity inner engine shocks. Yet,...
We present the extensive follow-up campaign on afterglow of GRB 110715A at 17 different wavelengths, from X-ray to radio bands, starting 81 seconds after burst and extending up 74 days later. performed for first time a observation with ALMA observatory. find that is very bright optical wavelengths. use near infrared spectroscopy provide further information about progenitor's environment its host galaxy. The spectrum shows weak absorption features redshift z = 0.8225, which reveal galaxy low...
The European Space Agency's Soil Moisture and Ocean Salinity (SMOS) mission is perturbed by Radio Frequency Interference (RFI) that jeopardizes part of its scientific retrieval in certain areas the world. Areas affected RFI experience data loss or underestimation soil moisture ocean salinity values. Close to 10th anniversary SMOS launch, this paper provides an overview activities during these years, evolution scenario worldwide lessons learned. main challenges faced detection geo-location...
No-Reference video quality assessment has become a trending and challenging hot topic in estimating perceived audiovisual content. In this paper, we present proposal to considerably reduce the computational cost of processing without losing accuracy QoE estimation. Tests have been performed using Video-MOS SaaS solution, hybrid NR-VQA solution based on perceptible distortions machine learning approach. After exploring spatial temporal redundancy sequence, final approach combines metric...

Our aim is to facilitate monitoring patient information, benefiting both caregivers healthcare professionals. Methods As part PROCare4Life platform sensorial ecosystem, a web application six engaging cognitive games focusing developing training stimulating brain activity are developed. A set metrics calculated by feed machine learning...
The evolution of telecommunication networks unlocks new possibilities for multimedia services, including enriched and personalized experiences. However, ensuring high Quality Service Experience requires intelligent solutions at the edge. This study investigates real-time detection race bib numbers using YOLOv8, a state-of-the-art object framework, within context 5G/6G edge computing. We train (BDBD SVHN datasets) analyze various YOLOv8 models (nano to extreme) across two diverse racing...
The issue of Radio Frequency Interference (RFI) is a widespread problem in most microwave Earth observation missions, and passive instruments are particularly sensitive to RFI. This the case for SMOS, Soil Moisture Ocean Salinity, satellite European Space Agency, which operates 1400–1427 MHz band, where all emissions prohibited. Notwithstanding this regulatory framework, SMOS has been affected by RFI around world since beginning operations 2010. In first years operations, manual detection...
The European Space Agency's Soil Moisture and Ocean Salinity (SMOS) mission operates in the 1400-1427 MHz frequency band, which is allocated to EESS (passive) service ITU Radio-Regulations. measurements of SMOS radiometer are perturbed by radio interference (RFI) that jeopardize part its scientific retrieval certain areas World.The strategies initiated Agency mitigate impact RFI includes detection, monitoring, reporting cases. Due large number sources detected, their temporal variability,...

Abstract Universal access on equal terms to audiovisual content is a key point for the full inclusion of people with disabilities in activities daily life. As real challenge current Information Society, it has been detected but not achieved an efficient way, due fact that solutions are mainly based traditional television standard and other automated high-cost solutions. The arrival new technologies within hybrid environment together application different artificial intelligence techniques...
Background: In the last decade, numerous methods have been proposed to define and detect outliers, particularly in complex environments like networks, where anomalies significantly deviate from normal patterns. Although defining a clear standard is challenging, anomaly detection systems become essential for network administrators efficiently identify resolve irregularities. Methods: This study develops evaluates machine learning-based system detection, focusing on point within traffic. It...
The SMOS (Soil Moisture and Ocean Salinity) satellite was launched on 2 November 2009, it is the ESA second Earth Explorer Opportunity mission. After almost 10 years of successful Operations, status mission excellent. However, observations are significantly affected by RF interference (RFI) in several world areas.Since first observations, its radiometer passive band 1400-1427 MHz detected RFI sources. Any emission this prohibited ITU Radio-Regulations (RR No.5340) [1]. To successfully...
CN006 is the name given by European Space Agency (ESA) in their reports on radio frequency interference (RFI) to an instance of RFI L-band spectral window at 1.413 GHz protected for passive use only. The source located east Chinese city Hangzhou area with radar installations. Its effect was initially indistinguishable from that many such sources observed ESA's SMOS and NASA's Soil Moisture Active Passive (SMAP) radiometers over China. However, July 2020, level radiation increased...
People with various degrees of disabilities (e.g., visually or hearing impaired) often find it difficult to access mainstream products and services thus they are excluded from enjoying audio-visual on an equal basis as people without disabilities. These feel marginalized in today's digital society unable reach their maximum potential personally, professionally socially. EasyTV aims address these issues by providing numerous that not only ease the multimedia services, but also enhance...
