Background: Cochlear implant has been providing hearing rehabilitation to patients with severe hearing loss. However, not all patients achieve optimal results, and the goal of this study was to evaluate the factors that influence hearing outcomes in cochlear implantation. Methods: This was a retrospective analysis of the patients who underwent cochlear implantation in our institution between 2018 and 2021. Review of clinical files and complementary tests, and analysis of hearing outcomes and complications were performed. Results: Sixty-nine cochlear implants were placed in 64 patients, with an average age of 49.3 years. In initial evaluation post activation and 1 year after implantation, the average pure tone average (PTA) was 37 dB, with a vocal discrimination of 48.7% at 50 dB, and 28, 6 dB, with a discrimination of 73.8% at 50 dB, respectively. Patients with postlingual deafness had better hearing outcomes at 1 year post surgery, in both PTA (27.9 compared to 33 dB) and discrimination at 50 dB (76.5 compared to 56.1%). Only one case had a major complication. Conclusions: In conclusion, we found that increased implant use by the patient, postlingual deafness, and in-creased surgeon experience, were factors that improved hearing outcomes in patients undergoing cochlear implantation.

In nucleus-nucleus collisions, the Quark-Gluon Plasma behaves like a perfect fluid and the azimuthal anisotropy of the observed particle final-state distributions reflects its properties.This anisotropic flow, arising mainly from initial-state geometry and its fluctuations, highlights the collective behavior of the particles produced in the collision.It is well-described by hydrodynamics and explains the long-range near-side correlations, known as the "ridge", observed experimentally in AA collisions and, more recently, in small systems such as pp or pA collisions.The CMS experiment has studied this correlation in details by extracting the momenta of the Fourier decomposition of azimuthal particle-distribution in the final state (v n , n = 2 -4).The v n are extracted using di-hadron correlation and multi-particle cumulant methods in both pp and pPb collisions.In this talk, results from CMS on the ridge in small systems are shown and compared with those in PbPb collisions, demonstrating that the collective nature of the ridge is present also in small systems.The correlation between different Fourier coefficients is further investigated using a symmetric cumulant analysis and compared across colliding systems.The latest results on v n correlations in pp at 13 TeV and pPb at 8.16 TeV collisions are also discussed.All these results give us a better understanding of collective effects from small to large colliding systems and provide more insights on the nature of the ridge in pp and pPb collisions.

This white paper summarizes the activities of the Brazilian community concerning dark matter physics and highlights the importance of financial support to Brazilian groups that are deeply involved in experimental endeavours. The flagships of the Brazilian dark matter program are the Cherenkov Telescope Array, DARKSIDE, SBN and LHC experiments, but we emphasize that smaller experiments such as DAMIC and CONNIE constitute important probes to dark sectors as well and should receive special attention. Small experimental projects showing the potential to probe new regions of parameter space of dark matter models are encouraged. On the theoretical and phenomenological side, some groups are devoted to astrophysical aspects such as the dark matter density profile while others explore the signature of dark matter models at colliders, direct and indirect detection experiments. In summary, the Brazilian dark matter community that was born not long ago has grown tremendously in the past years and now plays an important role in the hunt for a dark matter particle.

espanolEn este trabajo se analiza la morfodinamica de las dunas, playa y area sumergida proxima de un sector de 4,7 km desde Poco da Cruz hasta Mira (S de Aveiro, Portugal). Durante el invierno maritimo 2016/2017 se ha realizado un programa de monitorizacion costera incluyendo: 25 campanas topograficas de perfiles en dunas y playa con DGPS, mediciones hidrodinamicas (altura de ola y corrientes) y 2 campanas batimetricas antes y despues del invierno. El clima maritimo se ha caracterizado con datos obtenidos del modelo numerico SIMAR. Se cuantificaron los balances sedimentarios, variaciones de linea de costa y cambios en la pendiente dunar, entre otros parametros morfologicos. Los resultados muestran las zonas erosionadas y de mayor vulnerabilidad asi como tasas de retroceso (hasta -45 m) y avance (hasta +40 m) durante el invierno. Este estudio contribuye ademas al conocimiento de las caracteristicas tridimensionales de la playa y a determinar la influencia de los bancos de arena sumergidos en el comportamiento del sistema emergido playa-duna. EnglishThis study analyses the morphodynamics of dunes, beach and submerged proximal area in a 4.7 km coastal sector from Poco da Cruz to Mira (S of Aveiro, Portugal). During the winter of 2016/2017 a coastal monitoring programme was carried out including: 25 topographic surveys of dune and beach profiles with DGPS, local hydrodynamic measurements (wave height and currents) and 2 bathymetric surveys before and after winter. The maritime wave climate has been characterized by data base of the numerical model SIMAR. Sedimentary budget, coastline displacements (in frontal dune toe) and changes in dune slope were quantified, among other morphological parameters. The results highlight some features as a mean rate of coastline retreat (up to -45 m) and coastline progradation (up to +40 m), as well as the identification of eroded or most vulnerable zones during winter. This study also contributes to the knowledge of the three-dimensional beach characteristics and to determine the influence of submerged sandbanks in the behaviour of emerged beach-dune system.

In this work, we show the preliminary results on the 137Cs dating of the tidal flood sediments in the barrier-island system of Aveiro (Portugal). The ”7Cs activity enable us to establish four isochrones which limit the last four decades, through the correlation of historical data of137Cs atmospheric concentration. The sediment acumulation rates on the intertidal flat is calculated to be 0.6 cm yr1

This proposal concerns the participation of the Brazilian High-Energy Physics community in the next-generation collider experiments. As the LHC at CERN is getting ready for its third data-taking period, Run 3, with increased centre-of-mass energy at the nominal 14 TeV and upgraded detectors, the global High-Energy Physics community is converging towards the materialisation of new powerful colliders which could explore the characteristics of the Higgs boson and advance the search of physics beyond the Standard Model. This means that in the next couple of years the technical proposals for the experiments that will run in such colliders will be submitted for review, collaborations will be formed and large scale funding will be requested at different stages across the globe. Our aim is to organise a common effort from the Brazilian HEP community of optimised resources and time, in order to produce a higher impact contribution to our chosen experiment and more broadly in the field of High-Energy Physics.

In ultrarelativistic heavy-ion collisions, a very strong (on the order of 1016 T) and transient (lifetime on the order of 10−1 fm/c) electromagnetic (EM) field is expected to be generated inside the medium formed in the collision. This EM field, generated by the collision participants and spectators, is predicted to produce a difference in the νn harmonics for positive-and negative-charged particles, with the magnetic field mainly responsible for a splitting in rapidity-odd directed flow (ν1), and the Coulomb electric field leading to a charge-dependent splitting in the ν2 and average pT values of emitted particles. Due to the large mass, charm quarks are expected to be created very early in the collision, and thus have more chance of interacting with this strong EM field than light flavor hadrons. In this contribution, measurements of D0 (u‾c) and D‾0 uc‾) mesons flow harmonics (ν2 and ν3) are presented as functions of rapidity (y), transverse momentum, and collision centrality for PbPb collisions at 5.02 TeV, using the large data samples collected by the CMS experiment during the LHC Run 2. The wide rapidity coverage (|y| < 2) of these new charm mesons measurements allow for a better understanding of the 3-dimensional evolution of the medium formed in heavy-ion collisions.

The Mira channel, located in the inner domain of the Aveiro barrier-island complex, is subdivided in three sections: head, intermediate and mouth, according to their morphological and sedimentary features. Their study shows the zonation of the associated intertidal flat in five zones: sand flat, lower mud flat, mixed flat, upper mud flat and marsh, related to different tidal levels.

Facies analysis of the Upper Jurassic sequence, exposed along Cabo Mondego sea cliffs, suggest that their deposition occured under nearshore environments. These environments were controlled by tides and in sorne cases by storms. Five unites have been defined, wich correspond to three distinct sedimentary environments: shallow platform, bay and delta plain.

Three litoestratigraphic unites have been identified in the Sao Martinho do Porto sea cliffs, which correspond with three deltaic cycles. The paleocurrents analysis show that for the first two cycles, the sediments come from the Berlengas Massif situated in the SW; while the third come from the NE, controlled by the diapiric relief of the Caldas da Rainha

espanolSe describe un cuerpo sedimentario en el Mioceno de la Fosa de Ciudad Rodrigo (Espana). El litosoma ha sido interpretado como el deposito en un arco de meandro de un sistema fluvial de gravas, cuyo desarrollo ha estado condicionado por :eit~p·aleorelieve del borde este de la Fosa. El litosoma se ha dividido en cinco unidades sedimentarias que han sido relacionadas con los subambientes de «scour-pool», «point-barn bajo, canales de «chute», banco de acrecion y «overbank». Las facies que comprenden el arco de meandro se articulan en una secuencia compleja, cuya caracteristica principal es la ausencia de un trazado «fining-upward» bien definido. El arco de meandro esta compuesto por dos «point-bars» adyacentes que muestran diferente seccion a causa de un cambio en la direccion de desplazamiento del canal. EnglishA description is offered of a sedimentary body from the Miocene situated in the Ciudad Rodrigo Basin (Spain). The lithosome is interpreted as a coarse-grained meander loop whose development has been conditioned by the paleorelief of the eastern border of the basin. Five sedimentary units are established; these are related to the subenvironments of scour-pool, low point-bar, chute channels, accretionary bank and overbank deposition. The facies·comprising the meander loop are articulated in a complex sequence whose most salient characteristic is the absence of a well-defined fining upward trend. The meander loop is composed of two adjointing point-bars exhibiting different sections as the result of a change in the direction of the displacement of the channel
