“Ideologia de gênero” como instrumento político nos jornais do Brasil e de Portugal

Resumo: O conceito sociológico ‘ideologia de gênero’ foi ressignificado a partir dos anos 1990 e virou instrumento político contra as narrativas feministas e LGBT+. A politização da expressão é um desafio para os estudos de gênero e diversidade sexual, pois gera barreiras em políticas, na agenda de investigação e na ação transnacional junto aos governos, à mídia e a outros agentes sociais. Nessa análise de conteúdo, comparamos o uso da expressão na cobertura dos jornais de maior circulação digital do Brasil (Folha de S. Paulo) e de Portugal (Expresso) entre 2000 e 2019. O que essas coberturas informam sobre o atual estágio da disputa discursiva em torno dessa expressão? Os resultados indicam a consolidação do termo no viés conservador, padrões semelhantes nos discursos e perfis de quem o utiliza, e apontam que as maiores reações políticas acontecem quando o termo está associado aos temas ‘eleições’ e ‘educação’.
Recent results from the Large Hadron Collider

We present an overview of the physics results obtained by experiments at the Large Hadron Collider (LHC) in 2009–2010, for an integrated luminosity of L ≈ 40 pb−1, collected mostly at a centre-of-mass energy of √s = 7 TeV. After an introduction to the physics environment at the LHC and the current performance of the accelerator and detectors, we will discuss quantum chromodynamics and B-physics analyses, W and Z production, the first results in the top sector, and searches for new physics, with particular emphasis on supersymmetry and Higgs studies. While most of the presented results are in remarkable agreement with Standard Model predictions, the excellent performance of the LHC machine and experiments, the prompt analysis of all data within just a few months after the end of data taking, and the high quality of the results obtained constitute an encouraging step towards unique measurements and exciting discoveries in the 2011–2012 period and beyond.
Permissionless Blockchain-Based Sybil-Resistant Self-Sovereign Identity Utilizing Attested Execution Secure Processors

The current circumstance that requires people more online has encouraged us to address digital identity preserving privacy. There is a momentum of research addressing Self-Sovereign Identity (SSI); many research approach blockchain technology as a foundation. SSI brings natural persons various benefits such as their owning controls; on the other side, digital identity systems in the real world require Sybil-resistance to comply with Anti-Money-Laundering (AML) and other needs. Our proposal in this paper is to build a secure SSI system by utilizing permissionless blockchain and Rafael Pass et al.'s contribution of the formal abstraction of Attested Execution Secure Processors (AESPs). Our proposal of the AESP-based SSI architecture and system protocols, ∏Gatt, demonstrates the powerfulness of hardware-assisted security and the formal abstraction of AESPs, fitting into building a proper SSI system that satisfies Sybil-resistance. Assuming AESPs and Gatt, the protocols may eliminate the online distributed committee assumed in other research such as CanDID; thus, ∏Gatt allows not to rely on multiparty computation (MPC), and it brings drastic flexibility and efficiency compared with the existing SSI systems.
High Frequency Electromagnetic Propagation/Scattering Codes

Abstract : The objective of our effort was to develop computational methods for constructing high-frequency asymptotic solutions in scattering on perfectly conducting objects. The emphasis of the first stage of our work was to describe high frequency phenomena in terms of numerically implemented evolution of wave-fronts associated with the propagating waves. The wave-front evolution algorithm is implemented for the leading high frequency mechanisms including: free-space propagation, reflection on smooth surfaces, wave-front splitting at the shadow boundary, generation and propagation of edge diffracted wave-fronts, and surface wave propagation. The second stage of our work was directed towards developing novel fast rigorous (direct or iterative) solution methods based on construction of economical parameterization of high frequency solutions in terms of basis functions defined on large supports. The wave-front evolution technique developed in the first stage provides a numerical prescription for the selection and determination the parameters of the postulated analytical representation of such basis functions. The numerical prescription together with numerical tools constructed during this effort will constitute an important element of the planned future, high frequency solution technique employing basis functions defined on large supports.
Stability of Ti in NaAlH4

There has been confusion which external reference should be used for predicting ground state Ti substitution enthalpies in NaAlH4: element gaseous atomic states or standard states. It is proposed instead to use all the relevant product phases for the Ti-enhanced sodium alanate system as internal reference states. The results are similar to when external reference element standard states are used: Ti doping is unstable in NaAlH4, and substitution on the Al sublattice is the least unfavorable. Substitution near the surface is more favorable than in the bulk, thus metastable Ti substitution may occur close to interfaces, grain boundaries, or defects.
PSECO-IM: An Approach for Incident Management to Support Governance in Proprietary Software Ecosystems

Organizations that produce software cooperatively and competitively to satisfy customer needs give more attention in relationships among several actors (e.g., providers, developers, and IT managers) to build the value creation network called Software Ecosystem (SECO). As a type of SECO, proprietary SECO concerns data concentrated on a platform with contributions protected by intellectual property. The technological platform that supports the business initiatives is developed using different technologies with dozens of integration points, promoting a network of dependencies and architectural complexities. Some studies show that systems downtime (incidents) causes major image and financial upheavals for organizations. To mitigate the risks of incidents, the IT management team should implement strategies based on governance mechanisms to sustain the platform. Our work aims to develop and evaluate a process-based approach (PSECO-IM) for incident management to support the IT management team in the governance of a technology platform architecture in a proprietary SECO. We also addressed some of the identified challenges of quality in proprietary SECO, such as standardized software processes, knowledge management, and governance strategies. As a final result, we got positive feedback on the relevance of the tool in improving governance strategies related to incident management by the organization’s practitioners. We argue that this work is appropriate for the Software Quality area since it covers studies on three pillars: people, process, and technology, such as tacit knowledge, low-quality software, governance, incident management, and proprietary SECO.

Contributions of Early‐ and Middle‐Winter Perturbations at Higher Altitudes to Late‐Winter Anomalously Strong Arctic Polar Vortex in the Lower Stratosphere

Based on the Modern‐Era Retrospective analysis for Research Applications Version 2 reanalysis, an upper stratosphere/lower mesosphere (USLM) disturbance in early January and a sudden stratospheric warming (SSW) in early February are both coincidentally captured preceding the anomalously strong polar vortex during the late boreal winters of 2010/2011 and 2019/2020. Our analysis indicates that planetary wave breaking during the USLM disturbance and SSW decelerates the westerly polar night jet (PNJ) in the upper stratosphere, which leads to a continuous downward and poleward propagation of the PNJ during the early and middle winter. As the peak height of the PNJ descends, the region with negative vertical wind shear and negative waveguides also extends downward and reaches an altitude of ∼40 km during the late winter, which significantly limits the upward propagation of planetary waves, inducing a stable polar vortex in the lower stratosphere. In addition, the transformed Eulerian mean diagnostic results based on the specified dynamics simulation of the Whole Atmosphere Community Climate Model eXtended version confirm that the planetary wave‐induced downwelling is the main cause of the stratospheric warming during the two perturbations. More importantly, the simulation results indicate that the strength of the two upper stratospheric perturbations is appropriate to maintain the reflective configuration during the late winter, which suggests that such a specific sequence of perturbations during the early and middle winter, namely a USLM disturbance followed by a minor SSW, is favorable for the development of a late‐winter unusually strong Arctic polar vortex in the lower stratosphere.
Nonlinear Perron-Frobenius Theory

In the past several decades the classical Perron–Frobenius theory for nonnegative matrices has been extended to obtain remarkably precise and beautiful results for classes of nonlinear maps. This nonlinear Perron–Frobenius theory has found significant uses in computer science, mathematical biology, game theory and the study of dynamical systems. This is the first comprehensive and unified introduction to nonlinear Perron–Frobenius theory suitable for graduate students and researchers entering the field for the first time. It acquaints the reader with recent developments and provides a guide to challenging open problems. To enhance accessibility, the focus is on finite dimensional nonlinear Perron–Frobenius theory, but pointers are provided to infinite dimensional results. Prerequisites are little more than basic real analysis and topology.
The distribution of the galaxies

This topical volume examines one of the leading problems in astronomy today – how galaxies cluster in our Universe. Many observational surveys and theoretical projects are currently underway to understand the distribution of galaxies. This is the first book to describe gravitational theory, computer simulations, and observations related to galaxy distribution functions (a general method for measuring the clustering and velocities of galaxies). It embeds distribution functions in a broader astronomical context, including other exciting contemporary topics such as correlation functions, fractals, bound clusters, topology, percolation, and minimal spanning trees. Key results are derived and the necessary gravitational physics provided to ensure the book is self-contained. And throughout the book, theory, computer simulation, and observation are carefully interwoven and critically compared. The book also shows how future observations can test the theoretical models for the evolution of galaxy clustering at earlier times in our Universe. This clear and authoritative volume iswritten at a level suitable for graduate students and will be of key interest to astronomers, cosmologists, physicists, and applied statisticians.
The Multistage 20-m Shuttle Run Test for Predicting VO2Peak in 6–9-Year-Old Children: A Comparison with VO2Peak Predictive Equations

Simple Summary Cardiorespiratory fitness is one of the main components of physical fitness. For children, a simple test that can be used to assess cardiorespiratory fitness is the multistage 20-m shuttle run test (20mSRT). Research has often used a portable gas analyzer to measure cardiorespiratory fitness in clinical and scientific settings; however, this may not be practical due to the high cost of the device. Moreover, the use of such a device with children is almost impracticable in school environments. Thus, to avoid using such a device, one possibility is to use equations for predicting peak oxygen consumption, which is recognized as one of the best indicators of aerobic fitness. In the present study, 22 equations were used to determine which predictive equations had greater agreement with VO2peak values measured by direct oximetry through performance of the 20mSRT. Furthermore, we verified if wearing and carrying a portable gas analyzer constrained the children’s performances. To accomplish these aims, 67 boys and 63 girls were included in the analysis. Our results showed that only six predictive equations correctly predicted the peak oxygen consumption. In addition, for girls, higher values of maximal speed, total laps, and total time were found when a portable gas analyzer was used. This information is helpful to strength and conditioning professionals and to schoolteachers if portable gas analyzers are unavailable or if the environment is not suitable for such assessments. Abstract This study aimed (i) to verify if using and carrying a portable gas analyzer (PGA) constrained the performance of school children on the multistage 20-m shuttle run test (20mSRT), (ii) to verify which peak oxygen consumption (VO2peak) predictive equations have greater agreement with VO2peak values measured by direct oximetry using the 20mSRT. The study participants were 130 children ((67 boys (age 7.76 ± 0.97 years) and 63 girls (age 7.59 ± 0.91 years)), who performed two randomized trials of the 20mSRT with and without a PGA. Twenty-two predictive equations predicted the VO2peak values through the performance of the test with and without a PGA. Without a PGA, lower values of maximal speed (MS), total laps (TL), and total time (TT) were found for girls than for boys with a PGA. Only six equations were considered to correctly predict VO2peak. In general, higher MS, TL, and TT values were found with the use of a PGA. The predicted VO2peak values from the 20mSRT varied significantly among the published predictive equations. Therefore, we suggest that the six equations that presented satisfactory accuracy could be practically used to examine cardiorespiratory fitness in schools and in research with large populations when direct measurement of VO2peak is not feasible.
Preparation and Optimization of Ibrutinib-Loaded Nanoliposomes Using Response Surface Methodology

The main aim of this study was to optimize the formulation and process variables for the preparation of ibrutinib nanoliposomes and to evaluate the stability of nanoliposomes. The influence of four formulations and process parameters, namely, the phosphatidylcholine-to-cholesterol ratio (A), conc. of ibrutinib (B), sonication time (C), and stirring time (D) on the drug encapsulation efficiency (Y1) and particle size (Y2) of ibrutinib nanoliposomes were investigated by using response surface methodology. Reverse-phase evaporation was used to prepare ibrutinib nanoliposomes. Twenty-nine trial experiments were performed as per the design and the response parameters were noted. Multiple linear regression analysis was used to assess each response parameter. The effect of each factor on the response parameters was depicted using perturbation, response surface, and contour plots. A numerical optimization technique was used to estimate the optimum process parameters to obtain the desired responses. Ibrutinib nanoliposomes prepared under optimal conditions were evaluated for stability at a different temperature, pH, and sonication time. It is evident from the results that the phosphatidylcholine-to-cholesterol ratio (A) was the major factor influencing the encapsulation efficiency. All the factors were found to have noteworthy influences on particle size. A statistical evaluation provided the information about the individual and interactive effects of independent factors on the response parameters in order to obtain optimum experimental conditions that lead to preparing nanoliposomes with improved characteristics. The optimum level of the independent variables was phosphatidylcholine:cholesterol (6.76:1), ibrutinib concentration (2 mg/mL), sonication time (15.13 min), and stirring time (45 min). At optimal conditions, Y1 and Y2 were found to be 90.76 ± 1.56% and 208.24 ± 3.16 nm, respectively. The ibrutinib nanoliposomes were found to be stable both in simulated gastric and intestinal fluids at 37 °C for 6 h. At elevated conditions of temperature and pH, the prepared nanoliposomes were found to be unstable. Sonication for shorter periods resulted in decreased particle size, whereas longer periods can be helpful for ultrasound-assisted drug delivery. The closeness between the obtained results and predicted results indicates the reliability of the optimization technique for the preparation of ibrutinib nanoliposomes.
Predicting Personalized Head Movement From Short Video and Speech Signal

Audio-driven talking face video generation has attracted much attention recently. However, few existing works pay attention to machine learning of talking head movement, especially based on the phonetic study. Observing that real-world talking faces often accompany natural head movement, in this paper, we model the relation between speech signal and talking head movement, which is a typical one-to-many mapping problem. To solve this problem, we propose a novel two-step mapping strategy: (1) in the first step, we train an encoder that predicts a head motion behavior pattern (modeled as a feature vector) from the head motion sequence of a short video of 10–15 seconds, and (2) in the second step, we train a decoder that predict a unique head motion sequence from both the motion behavior pattern and the auditory features of an arbitrary speech signal. Based on the proposed mapping strategy, we build a deep neural network model that takes a speech signal of a source person and a short video of a target person as input, and outputs a synthesized high-fidelity talking face video with personalized head pose. Extensive experiments and a user study show that our method can generate high-quality personalized head movement in synthesized talking face videos, and meanwhile, has comparable facial animation quality (e.g., lip synchronization and expression) with the state-of-the-art methods.
To Investigate the Refractive Index of Blood Plasma Suspended in Various Tonicity Solutions

This paper reports the data of the RI of plasma of normal blood, which is measured using Abbes' refractometer. The experimental values are compared to normal blood serum erythrocytes with Blood of Plasma suspended in various tonicity solutions between and 1.336 to 1.343, whereas the normal blood plasma refractive index is 1.351. As a result, the refractive index the worth of erythrocytes washed with different tonicity solutions are slightly lower than those of normal blood. If this optical parameter is standardized, it has the potential to be used as a tool in the medical field.
High Quality Pt–Pt Metal Bonding for High Temperature Packaging

Platinum is an ideal material for high-temperature resistant device packaging due to its higher melting point and good electrical properties. In this paper, the thermocompression bonding of Pt–Pt metal electrodes was successfully realized through process exploration, and the package interconnection that meets the requirements was formed. A square bump with a side length of 160 µm and a sealing ring with a width of 80 µm were fabricated by magnetron sputtering. Different pressure parameters were selected for chip-level bonding; the bonding temperature was 350 °C for about 20 min. Analysis of the interface under a scanning electron microscope found that the metal Cr diffused into Pt. It was found that two chips sputtered with 300 nm metal Pt can achieve shear resistance up to 30 MPa by flip-chip bonding at 350 °C and 100 MPa temperature and pressure, respectively. The leakage rate of the sample is less than 2 × 10–3 Pa·cm3/s, the bonding interface is relatively smooth, and the hot-pressed metal bonding of Pt electrodes with good quality is realized. By comparing the failure rates at different temperatures and pressures, the process parameters for Pt–Pt bonding with higher success rates were obtained. We hope to provide new ideas and methods for the packaging of high-temperature resistant devices.
Neutron Star Crust and Molecular Dynamics Simulation

In this book chapter we review plasma crystals in the laboratory, in the interior of white dwarf stars, and in the crust of neutron stars. We describe a molecular dynamics formalism and show results for many neutron star crust properties including phase separation upon freezing, diffusion, breaking strain, shear viscosity and dynamics response of nuclear pasta. We end with a summary and discuss open questions and challenges for the future.
A study of unknown X-ray sources

We analyze the X-ray spectra and light curves of five unknown X-ray sources found in the observations obtained by the XMM-Newton satellite. For two objects we have found X-ray flares. Three other objects have X-ray spectra similar to those of enigmatic 𝛾 Cas analogs and may be new candidates for such stars. All the considered sources are faintly visible in the DSS optical images. We suggest that all the studied objects can be either very distant stars or transient sources. Multifaceted
A Fast Monocular Visual–Inertial Odometry Using Point and Line Features

Most SLAM systems using point feature reduce the pose accuracy or crash due to the small number of point features are extracted under the light-dark mutation environment or low texture area. In order to improve the robustness and pose accuracy of the SLAM, a fast monocular visual–inertial odometry using point and line features is proposed in this paper. Firstly, the point and line features of the image are extracted for feature matching, and the IMU measurement data is extracted as the initialization state estimation information of the sliding window. The following IMU measurements are pre-integrated to constrain the successive IMU body states during optimization. Secondly, the proposed VIO uses geometric constraints to delete point-line matching outliers, and point-line feature endpoints are projected into a normalized plane for triangulation to build re-projection residuals. Finally, after obtaining the initial estimation of this system and the IMU body state predicted by IMU measurement, the sliding window optimization method is used to get the precise position of camera. The experiments are evaluated on public datasets (EuRoc MAV dataset and PennCOSYVIO dataset). The pose accuracy of this algorithm is more accurate than VINS-mono, and the speed is faster than PL-VIO.
