Multi-strange baryon measurements at LHC energies, with the ALICE experiment
The status of the charged multi-strange baryon analysis (Xi-, anti-Xi+,
Omega-, anti-Omega+) at LHC energies is presented. This report is based on the
results obtained with ALICE (A Large Ion Collider Experiment), profiting from
the characteristic cascade-decay topology. A special attention is drawn to the
early pp data-taking period (2009-2010) and subsequently, on the uncorrected
pT-spectra extracted at mid-rapidity for centre of mass energies of 0.9 TeV and
7 TeV.Comment: 4 pages, 5 figures, Hot Quarks 2010 proceedings, La Londe Les Maures,

Os reflexos afetivos do acolhimento institucional e familiar de crianças e adolescentes
A presente monografia objetiva realizar uma análise dos reflexos jurĂdicos e afetivos do acolhimento institucional e familiar de crianças e adolescentes, observando a sociedade contemporânea e as diversas formas de famĂlias existentes na atualidade. O mĂ©todo utilizado no presente estudo Ă© o dedutivo, com referĂŞncias bibliográfica e documental. A pesquisa Ă© qualitativa. O iniciará pelos aspectos fĂsicos e emocionais das crianças e adolescentes, descrevendo noções gerais, conceituais e histĂłricas, passando pela sociedade contemporânea e famĂlia atual, descrevendo os aspectos relevantes sobre a doutrina da proteção integral, princĂpios e direitos relativos Ă criança e ao adolescente, atĂ© chegar ao acolhimento institucional e familiar de crianças e adolescentes analisando os reflexos afetivos. Nesse sentido, conclui-se que embora existam legislações e normativas pertinente à área infanto-juvenil capazes de proteger a criança e o adolescente de qualquer forma de violĂŞncia, ainda se fazem necessários as suas aplicações de forma mais eficaz. Importante mencionar, que a tudo isso, corroborasse a questĂŁo cultural em que os mesmos estĂŁo inseridos refletindo na sua histĂłria de vida
The Author at Work – Two Short Stories by Janet Frame
This paper deals with two short stories written by the New Zealand born writer Janet Frame both of which represent the figure of the author, grappling with her own failure. The author figure takes us behind the scenes of the writing process, into the workshop of her fiction, therefore transforming us readers into voyeurs, and possibly intruders into her very own home, that of fiction – a home within/behind the home
Research evidence to support primary school inspection post-COVID
This policy briefing is intended to inform
discussion on how Ofsted inspections might
best resume at an appropriate time, given
the extensive disruption COVID has brought
and continues to bring to English primary
schools. The briefing draws on findings from
a series of research projects based at the IOE,
UCL’s Faculty of Education and Society and
conducted between May 2020 and September
2021, using surveys, systematic literature
reviews and case study methods.
The research projects have highlighted just
how much schools’ experiences have varied.
They also show just how resourceful and
resilient schools and their communities have
been in navigating a way through the many
difficult dilemmas the pandemic has raised,
even when there have been no obvious
roadmaps to follow.
The research evidence we present and the
recommendations that follow are intended
to inform conversations in the field about
the best ways forward in education. They
build on the knowledge and experience that
primary schools have acquired from dealing
with the pandemic first hand
Physics of the Muon Spectrometer of the ALICE Experiment
The main goal of the Muon spectrometer of the ALICE experiment at LHC is the
measurement of heavy quark production in p+p, p+A and A+A collisions at LHC
energies, via the muonic channel. Physics motivations and expected performances
have been presented in this talk.Comment: 10 pages and 4 figures. Talk presented in the ICPAQGP Conference,

Sleep Stages Classification Using Spectral Based Statistical Moments as Features
In the pursuit of highly effective and efficient portable sleep classification systems, researchers have been testing a massive number of combinations of EEG features and classifiers. Â State of art sleep classification ensembles achieve accuracy in the order of 90%. Â However, there is presently no consensus regarding the best setof features for sleep staging with single channel EEG, leading researchers to modify feature selection according to the number of classification stages. This paper introduces a reduced set of frequency-domain features capable of yielding high classification accuracy (90.9%, 91.8%, 92.4%, 94.3% and 97.1%) for all 6- to 2-state sleep stages. Â The proposed system uses fast Fourier transform (FFT) to convert data from Pz-Oz EEG channel into the frequency domain. Afterwards, eight statistical features are extracted from specific frequency ranges and fed into a random forest classifier
Femtoscopic scales in central A+A collisions at RHIC and LHC energies in hydrokinetic model
A study of the energy behavior of the interferometry radii is carried out for
the RHIC and LHC energies within the hydrokinetic model (HKM). The hydrokinetic
predictions for the HBT radii at LHC energies are compared with the recent
results of the ALICE Collaboration. The role of non-equilibrium and
non-hydrodynamic stage of the matter evolution in formation of the femtoscopy
scales at the LHC energies is analyzed. For this aim we develop the hybrid
hydrokinetic model.Comment: Talk presented by Yuri Sinyukov at "Quark Matter - 2011", May 23-28

Mesoscale eddies influence the movements of mature female white sharks in the Gulf Stream and Sargasso Sea

The definitive version was published in Scientific Reports 8 (2018): 7363, doi:10.1038/s41598-018-25565-8.Satellite-tracking of mature white sharks (Carcharodon carcharias) has revealed open-ocean movements spanning months and covering tens of thousands of kilometers. But how are the energetic demands of these active apex predators met as they leave coastal areas with relatively high prey abundance to swim across the open ocean through waters often characterized as biological deserts? Here we investigate mesoscale oceanographic variability encountered by two white sharks as they moved through the Gulf Stream region and Sargasso Sea in the North Atlantic Ocean. In the vicinity of the Gulf Stream, the two mature female white sharks exhibited extensive use of the interiors of clockwise-rotating anticyclonic eddies, characterized by positive (warm) temperature anomalies. One tagged white shark was also equipped with an archival tag that indicated this individual made frequent dives to nearly 1,000 m in anticyclones, where it was presumably foraging on mesopelagic prey. We propose that warm temperature anomalies in anticyclones make prey more accessible and energetically profitable to adult white sharks in the Gulf Stream region by reducing the physiological costs of thermoregulation in cold water. The results presented here provide valuable new insight into open ocean habitat use by mature, female white sharks that may be applicable to other large pelagic predators.This work was supported by the WHOI Ocean Life Institute and awards from NASA and NSF
