Acompanhamento clínico de crianças com distúrbios respiratórios do sono

INTRODUCTION:the evolution of snoring and OSAS in children is not well established since few studies of patients without surgical treatment have been published.OBJECTIVE:to evaluate the evolution of sleep disordered breathing in children who had not been submitted to upper airway surgery.METHOD:twenty-six children with snoring who had not undergone upper airway surgery were evaluated prospectively. Patients were evaluated by full physical examination and nocturnal polysomnography, after which they were divided into 2 groups: apnea (16 children) and snoring (10 children). After 6 months following the initial evaluation, patients were submitted to a new nocturnal polysomnography, and all data were compared to those of the first examination.RESULTS:the groups did not show any differences regarding age, weight, height and airway physical examination. After 6 months of follow-up, the apnea index did not change, but the respiratory disturbance index increased in the snoring group and the number of hypopneas decreased in the group apnea.CONCLUSION:there was an increase in the percentage of N1 sleep stage and the respiratory disturbance index in the patients with primary snore. The AHI did not show significant alteration in both groups, but the number of hypopneas decreased in patients with SAOS.INTRODUÇÃO:a evolução do ronco e da síndrome da apneia/hipoapneia obstrutiva do sono (SAOS) na infância ainda não está bem estabelecida e poucos estudos desses pacientes sem o tratamento cirúrgico foram publicados.OBJETIVO:avaliar a evolução da apneia e do ronco primário em crianças que não foram submetidas a cirurgia das vias aéreas superiores.MÉTODOS:foram avaliadas prospectivamente 26 crianças com ronco que não haviam sido submetidas a tratamento cirúrgico. Todas foram submetidas a exame físico, nasofibroscopia e polissonografia, a partir dos quais foram divididos em dois grupos: SAOS (16 crianças) e ronco (10 crianças). Após 6 meses da avaliação inicial, os exames foram repetidos, e os dados encontrados foram comparados.RESULTADOS:os grupos não apresentaram diferença entre si comparando idade, peso, altura e exame físico. Quando comparamos os resultados das duas polissonografias, houve um aumento da porcentagem do estágio do sono N1 no grupo ronco. O índice de apneia/hipoapnéeia (IAH) não apresentou alteração em ambos os grupos, o índice de distúrbios respiratórios (IDR) aumentou no grupo ronco, e o número de hipopneias diminuiu no grupo SAOS.CONCLUSÃO:houve aumento da porcentagem do estágio 1 do sono não-REM e do IDR nos pacientes com ronco primário; o IAH não apresentou alteração significante; o número de hipoapneias diminuiu nos pacientes com SAOS.Universidade Federal de São Paulo (UNIFESP) Department of Otorhinolaryngology and Head and Neck SurgeryUniversidade Federal de São Paulo (UNIFESP)Instituto do SonoUniversidade Federal de São Paulo (UNIFESP) Department of PsychobiologyUNIFESP, Department of Otorhinolaryngology and Head and Neck SurgeryUNIFESP, Department of PsychobiologySciEL
Constraints on two-neutron separation energy in the Borromean C-22 nucleus

The recently extracted matter radius of carbon isotope C-22 allows us to estimate the mean-square distance of a halo neutron with respect to the center-of-mass of this nucleus. By considering this information, we suggest an energy region for an experimental investigation of the unbound C-21 virtual state. Our analysis, in a renormalized zero-ranged three-body model, also indicates that the two-neutron separation energy in C-22 is expected to be found below similar to 0.4 MeV, where the C-22 is approximated by a Borromean configuration with a pointlike C-20 and two s-wave halo neutrons. A virtual-state energy of C-21 close to zero, would make the C-22, within Borromean nuclei configurations, the most promising candidate to present an excited bound Efimov state or a continuum three-body resonance.

Mesh adaptation on the sphere using optimal transport and the numerical solution of a Monge-Ampère type equation

An equation of Monge-Ampère type has, for the first time, been solved numerically on the surface of the sphere in order to generate optimally transported (OT) meshes, equidistributed with respect to a monitor function. Optimal transport generates meshes that keep the same connectivity as the original mesh, making them suitable for r-adaptive simulations, in which the equations of motion can be solved in a moving frame of reference in order to avoid mapping the solution between old and new meshes and to avoid load balancing problems on parallel computers. The semi-implicit solution of the Monge-Ampère type equation involves a new linearisation of the Hessian term, and exponential maps are used to map from old to new meshes on the sphere. The determinant of the Hessian is evaluated as the change in volume between old and new mesh cells, rather than using numerical approximations to the gradients. OT meshes are generated to compare with centroidal Voronoi tessellations on the sphere and are found to have advantages and disadvantages; OT equidistribution is more accurate, the number of iterations to convergence is independent of the mesh size, face skewness is reduced and the connectivity does not change. However anisotropy is higher and the OT meshes are non-orthogonal. It is shown that optimal transport on the sphere leads to meshes that do not tangle. However, tangling can be introduced by numerical errors in calculating the gradient of the mesh potential. Methods for alleviating this problem are explored. Finally, OT meshes are generated using observed precipitation as a monitor function, in order to demonstrate the potential power of the technique
Capture cross section measurements of 186,187,188-Os at n TOF: the resolved resonance region

The neutron capture cross sections of 186,187,188Os have been measured at the CERN neutron time-of-flight\ud
facility, n TOF, in the neutron energy range from 1 eV up to 1MeV. In this contribution, we report the results of the\ud
analysis of the resolved resonance region (RRR). Resonance parameters have been extracted from a full R-matrix\ud
fit of the capture yields with the SAMMY code. A statistical analysis has been performed and the related average\ud
resonance parameters are derived. This information is crucial for a complete understanding and modeling in terms of\ud
the Hauser-Feshbach statistical model of the capture and inelastic reaction channels, required for the evaluation of the\ud
stellar reaction rates of these isotopes. Maxwellian average cross sections for the range of temperatures relevant\ud
for s-process nucleosynthesis have been derived from the combined information of the experimental data in the\ud
resolved and unresolved resonance regions. A brief account of the implications of this analysis in the estimation of the\ud
s-process component of the 187Os abundance and the related impact on the estimates of the time-duration of\ud
the galactic nucleosynthesis through the Re/Os clock is given.Postprint (published version
Reaction-diffusion finite element model of lateral line primordium migration to explore cell leadership

Collective cell migration plays a fundamental role in many biological phenomena such as immune response, embryogenesis and tumorigenesis. In the present work, we propose a reaction–diffusion finite element model of the lateral line primordium migration in zebrafish. The population is modelled as a continuum with embedded discrete motile cells, which are assumed to be viscoelastic and able to undergo large deformations. The Wnt/ß-catenin–FGF and cxcr4b–cxcr7b signalling pathways inside the cohort regulating the migration are described through coupled reaction–diffusion equations. The coupling between mechanics and the molecular scenario occurs in two ways. Firstly, the intensity of the protrusion–contraction movement of the cells depends on the cxcr4b concentration. Secondly, the intra-synchronization between the active deformations and the adhesion forces inside each cell is triggered by the cxcr4b–cxcr7b polarity. This influences the inter-synchronization between the cells and results in two main modes of migration: uncoordinated and coordinated. The main objectives of the work were (i) to validate our assumptions with respect to the experimental observations and (ii) to decipher the mechanical conditions leading to efficient migration of the primordium. To achieve the second goal, we will specifically focus on the role of the leader cells and their position inside the population
New nurses burnout and workplace wellbeing:The influence of authentic leadership and psychological capital

The detrimental effects of burnout on nurses’ health and wellbeing are well documented and positive leadership has been shown to be an important organizational resource for discouraging the development of burnout. Intrapersonal resources also play a protective role against workplace stressors. This study investigated the influence of authentic leadership, an organizational resource, and psychological capital, an intrapersonal resource, on new graduate burnout, occupational satisfaction, and workplace mental health over the first year of employment (n = 205). Results supported the protective role of organizational and intrapersonal resources against burnout, job dissatisfaction, and mental health. © 2014 The Authors. Published by Elsevier GmbH.

Short-period X-ray oscillations in super-soft novae and persistent super-soft sources

Context. Transient short-period (<100 s) oscillations have been found in the X-ray light curves of three novae during their super-soft source (SSS) phase and in one persistent SSS.\ud
\ud
Aims. We pursue an observational approach to determine possible driving mechanisms and relations to fundamental system parameters such as the white dwarf mass.\ud
\ud
Methods. We performed a systematic search for short-period oscillations in all available XMM-Newton and Chandra X-ray light curves of persistent SSS and novae during their SSS phase. To study time evolution, we divided each light curve into short time-segments and computed power spectra. We then constructed a dynamic power spectrum from which we identified transient periodic signals even when only present for a short time. We base our confidence levels on simulations of false-alarm probability for the chosen oversampling rate of 16, corrected for multiple testing based on the number of time segments. From all time segments of each system, we computed fractions of time when periodic signals were detected.\ud
\ud
Results. In addition to the previously known systems with short-period oscillations, RS Oph (35 s), KT Eri (35 s), V339 Del (54 s), and Cal 83 (67 s), we found one additional system, LMC 2009a (33 s), and also confirm the 35 s period from Chandra data of KT Eri. The oscillation amplitudes are of about <15% of the respective count rates and vary without any clear dependence on the X-ray count rate. The fractions of the time when the respective periods were detected at 2σ significance (duty cycle) are 11.3%, 38.8%, 16.9%, 49.2%, and 18.7% for LMC 2009a, RS Oph, KT Eri, V339 Del, and Cal 83, respectively. The respective highest duty cycles found in a single observation are 38.1%, 74.5%, 61.4%, 67.8%, and 61.8%.\ud
\ud
Conclusions. Since fast rotation periods of the white dwarfs as origin of these transient oscillations are speculative, we concentrate on pulsation mechanisms. We present initial considerations predicting the oscillation period to scale linearly with the white dwarf radius (and thus mass), weakly with the pressure at the base, and luminosity. Estimates of the size of the white dwarf could be useful for determining whether these systems are more massive than typical white dwarfs, and thus whether they are growing from accretion over time. Signs of such mass growth may have implications for whether some of these systems are attractive as Type Ia supernova progenitors.Peer-reviewedPublisher Versio
Reconstruction of ice-sheet changes in the Antarctic Peninsula since the Last Glacial Maximum.

This paper compiles and reviews marine and terrestrial data constraining the dimensions and configuration of the Antarctic Peninsula Ice Sheet (APIS) from the Last Glacial Maximum (LGM) through deglaciation to the present day. These data are used to reconstruct grounding-line retreat in 5 ka time-steps from 25 ka BP to present. Glacial landforms and subglacial tills on the eastern and western Antarctic Peninsula (AP) shelf indicate that the APIS was grounded to the outer shelf/shelf edge at the LGM and contained a series of fast-flowing ice streams that drained along cross-shelf bathymetric troughs. The ice sheet was grounded at the shelf edge until ∼20 cal ka BP. Chronological control on retreat is provided by radiocarbon dates on glacimarine sediments from the shelf troughs and on lacustrine and terrestrial organic remains, as well as cosmogenic nuclide dates on erratics and ice moulded bedrock. Retreat in the east was underway by about 18 cal ka BP. The earliest dates on recession in the west are from Bransfield Basin where recession was underway by 17.5 cal ka BP. Ice streams were active during deglaciation at least until the ice sheet had pulled back to the mid-shelf. The timing of initial retreat decreased progressively southwards along the western AP shelf; the large ice stream in Marguerite Trough may have remained grounded at the shelf edge until about 14 cal ka BP, although terrestrial cosmogenic nuclide ages indicate that thinning had commenced by 18 ka BP. Between 15 and 10 cal ka BP the APIS underwent significant recession along the western AP margin, although retreat between individual troughs was asynchronous. Ice in Marguerite Trough may have still been grounded on the mid-shelf at 10 cal ka BP. In the Larsen-A region the transition from grounded to floating ice was established by 10.7–10.6 cal ka BP. The APIS had retreated towards its present configuration in the western AP by the mid-Holocene but on the eastern peninsula may have approached its present configuration several thousand years earlier, by the start of the Holocene. Mid to late-Holocene retreat was diachronous with stillstands, re-advances and changes in ice-shelf configuration being recorded in most places. Subglacial topography exerted a major control on grounding-line retreat with grounding-zone wedges, and thus by inference slow-downs or stillstands in the retreat of the grounding line, occurring in some cases on reverse bed slopes
Measurements of four-lepton production in $pp$ collisions at $\sqrt{s}=$
  8 TeV with the ATLAS detector

The four-lepton ($4\ell$, $\ell = e, \mu$) production cross section is
measured in the mass range from 80 to 1000 GeV using 20.3 fb$^{-1}$ of data in
$pp$ collisions at $\sqrt{s}=8$ TeV collected with the ATLAS detector at the
LHC. The $4\ell$ events are produced in the decays of resonant $Z$ and Higgs
bosons and the non-resonant $ZZ$ continuum originating from $q\bar q$, $gg$,
and $qg$ initial states. A total of 476 signal candidate events are observed
with a background expectation of $26.2 \pm 3.6$ events, enabling the
measurement of the integrated cross section and the differential cross section
as a function of the invariant mass and transverse momentum of the four-lepton
system.
  In the mass range above $180$ GeV, assuming the theoretical constraint on the
$q\bar q$ production cross section calculated with perturbative NNLO QCD and
NLO electroweak corrections, the signal strength of the gluon-fusion component
relative to its leading-order prediction is determined to be $\mu_{gg}=2.4 \pm
1.0 (stat.) \pm 0.5 (syst.)\pm 0.8 (theory)$.Comment: 20 pages plus author list + cover pages (37 pages total), 5 figures,

Fusion rules for the logarithmic $N=1$ superconformal minimal models II:
  including the Ramond sector

The Virasoro logarithmic minimal models were intensively studied by several
groups over the last ten years with much attention paid to the fusion rules and
the structures of the indecomposable representations that fusion generates. The
analogous study of the fusion rules of the $N=1$ superconformal logarithmic
minimal models was initiated in arXiv:1504.03155 as a continuum counterpart to
the lattice explorations of arXiv:1312.6763. These works restricted fusion
considerations to Neveu-Schwarz representations. Here, this is extended to
include the Ramond sector. Technical advances that make this possible include a
fermionic Verlinde formula applicable to logarithmic conformal field theories
and a twisted version of the fusion algorithm of Nahm and Gaberdiel-Kausch. The
results include the first construction and detailed analysis of logarithmic
structures in the Ramond sector.Comment: 42 pages, 7 figures; v2 fixed minor typos and added a little more

Measurement of the double-differential high-mass Drell-Yan cross section
  in pp collisions at $\sqrt{s}$ = 8 TeV with the ATLAS detector

This paper presents a measurement of the double-differential cross section
for the Drell-Yan $Z/\gamma^{*} \rightarrow \ell^{+} \ell^{-}$ and
photon-induced $\gamma\gamma \rightarrow \ell^{+} \ell^{-}$ processes where
$\ell$ is an electron or muon. The measurement is performed for invariant
masses of the lepton pairs, $m_{\ell\ell}$, between 116 GeV and 1500 GeV, using
a sample of 20.3 fb$^{-1}$ of pp collisions data at centre-of-mass energy of
$\sqrt{s}$ = 8 TeV collected by the ATLAS detector at the LHC in 2012. The data
are presented double differentially in invariant mass and absolute dilepton
rapidity as well as in invariant mass and absolute pseudorapidity separation of
the lepton pair. The single-differential cross section as a function of
$m_{\ell\ell}$ is also reported. The electron and muon channel measurements are
combined and a total experimental precision of better than 1% is achieved at
low $m_{\ell\ell}$. A comparison to next-to-next-to-leading order perturbative
QCD predictions using several recent parton distribution functions and
including next-to-leading order electroweak effects indicates the potential of
the data to constrain parton distribution functions. In particular, a large
impact of the data on the photon PDF is demonstrated.Comment: 43 pages plus author list + cover pages (61 pages total), 13 figures,

Formation of X-ray emitting stationary shocks in magnetized protostellar
  jets

X-ray observations of protostellar jets show evidence of strong shocks
heating the plasma up to temperatures of a few million degrees. In some cases,
the shocked features appear to be stationary. They are interpreted as shock
diamonds. We aim at investigating the physics that guides the formation of
X-ray emitting stationary shocks in protostellar jets, the role of the magnetic
field in determining the location, stability, and detectability in X-rays of
these shocks, and the physical properties of the shocked plasma. We performed a
set of 2.5-dimensional magnetohydrodynamic numerical simulations modelling
supersonic jets ramming into a magnetized medium and explored different
configurations of the magnetic field. The model takes into account the most
relevant physical effects, namely thermal conduction and radiative losses. We
compared the model results with observations, via the emission measure and the
X-ray luminosity synthesized from the simulations. Our model explains the
formation of X-ray emitting stationary shocks in a natural way. The magnetic
field collimates the plasma at the base of the jet and forms there a magnetic
nozzle. After an initial transient, the nozzle leads to the formation of a
shock diamond at its exit which is stationary over the time covered by the
simulations (~ 40 - 60 yr; comparable with time scales of the observations).
The shock generates a point-like X-ray source located close to the base of the
jet with luminosity comparable with that inferred from X-ray observations of
protostellar jets. For the range of parameters explored, the evolution of the
post-shock plasma is dominated by the radiative cooling, whereas the thermal
conduction slightly affects the structure of the shock.Comment: Accepted for publication in Astronomy and Astrophysic
Bacillus licheniformis Anti-TRAP can assemble into two types of dodecameric particles with the same symmetry but inverted orientation of trimers.

Comparative StudyAnti-TRAP (AT) protein regulates expression of tryptophan biosynthetic genes by binding to the trp RNA-binding attenuation protein (TRAP) and preventing its interaction with RNA. Bacillus subtilis AT forms trimers that can either interact with TRAP or can further assemble into dodecameric particles. To determine which oligomeric forms are preserved in AT proteins of other Bacilli we studied Bacillus licheniformis AT which shares 66% sequence identity with the B. subtilis protein. We show that in solution B. licheniformis AT forms stable trimers. In crystals, depending on pH, such trimers assemble into two different types of dodecameric particles, both having 23 point group symmetry. The dodecamer formed at pH 6.0 has the same conformation as previously observed for B. subtilis AT. This dodecamer contains a large internal chamber with the volume of approximately 700 A(3), which is lined by the side chains of twelve valine residues. The presence of the hydrophobic chamber hints at the possibility that the dodecamer formation could be induced by binding of a ligand. Interestingly, in the dodecamer formed at pH 8.0 all trimers are turned inside out relatively to the form observed at pH 6.0.National Institute for Health Research (NIHR)Wellcome Trus
Quantitative trait loci (QTLs) analysis of palm oil fatty acid composition in an interspecific pseudo-backcross from #Elaeis oleifera# (H.B.K.) Cortés and oil palm (#Elaeis guineensis# Jacq.)

We chose an Elaeis interspecific pseudo-backcross of first generation (E. oleifera × E. guineensis) × E. guineensis to identify quantitative trait loci (QTLs) for fatty acid composition of palm oil. A dense microsatellite linkage map of 362 loci spanned 1.485 cM, representing the 16 pairs of homologous chromosomes in the Elaeis genus from which we traced segregating alleles from both E. oleifera and E. guineensis grandparents. The relative linear orders of mapped loci suggested the probable absence of chromosome rearrangements between the E. oleifera and E. guineensis genomes. A total of 19 QTL associated to the palm oil fatty acid composition were evidenced. The QTL positions and the species origin as well as the estimated effects of the QTL marker alleles were in coherence with the knowledge of the oil biosynthesis pathway in plants and with the individual phenotypic correlations between the traits. The mapping of chosen Elaeis key genes related to oleic acid C18:1, using intra-gene SNPs, supported several QTLs underlying notably FATA and SAD enzymes. The high number of hyper-variable SSR loci of known relative linear orders and the QTL information make these resources valuable for . (Résumé d'auteur
