Abstract
We have fabricated large-diameter, high-quality gallium nitride (GaN) substrates by the multipoint seed (MPS) technique in the Na-flux method. To obtain crack-free freestanding GaN crystals, in this study we employed laser-assisted separation (LAS) as a new technique to separate GaN from a sapphire substrate. In LAS, the GaN crystal around the GaN-sapphire interface is partially decomposed by irradiating a laser onto the seed substrate before growth. Since this technique reduces the contact area between the sapphire and GaN, separation occurs spontaneously during the cooling process after growth. We found an appropriate LAS processing pattern for separation and successfully obtained freestanding GaN crystal without cracks. By combining LAS with the MPS method, we succeeded in growing crack-free crystals even in film thicknesses in which cracks occur in conventional MPS substrates.
Performance of a New Dynamic TS Protocol with Intelligent Battery Management in a Full-Duplex Relay Network
Authors: Agrawal Kamal , Prakriya Shankar , Singh Keshav 
Published: November 2023

<p>In this paper, the performance of a two-hop cooperative network is analyzed assuming the use of a channel-aware dynamic time-switching (TS) energy harvesting (EH) protocol at the battery-assisted EH full-duplex relay node. In such networks, node-level energy considerations are important for efficient battery utilization but have not attracted research attention. Two battery management schemes are considered. In the first scheme, fixed battery energy (FBE) is added to the harvested energy. To further improve performance, a new dynamic battery energy (DBE) scheme is considered in which the amount of battery energy drawn is channel dependent. The performance of the network is analyzed with both FBE and DBE schemes for static and dynamic TS schemes assuming a practical nonlinear EH model. Expressions are also presented for the average battery energy consumption in each case. It is demonstrated that joint optimization of the average battery energy consumption and the TS parameter is important. It is also demonstrated that the proposed dynamic TS protocol provides substantial gains in throughput and average energy savings compared to the static TS protocol with both FBE and DBE. The derived insights can aid a system designer. Computer simulations validate the derived expressions.</p>

Published: November 2023

Abstract: Universities have been a space for theoretical formulations and practical experiments, together with social movements and peripheral communities, supporting popular demands and public policies. Faced with the crisis, the increase in unemployment, poverty, hunger and social inequalities, the research deals with the contributions of universities to the construction of prospects for development and social well-being, for a new cycle of national reconstruction in times of pandemics. Among the actions, the initiatives in Emancipatory and Solidarity Economies point to practices of cooperation and care, associated and self-managed work, technological and sustainable practices, little known in society. To contribute to the systematization and dissemination of these actions, as part of research by the Center SoU_Ciência/Unifesp, dedicated to the defense of science and public universities, the research has mapped university extensionist groups and actions in this subject, active in networks and collaborations with society and governments. Through a bibliographical review, selection of sources and interviews with relevant actors at the head of national articulations and in dialogue with public policies, the study seeks to base the creation of a Panel, with a Timeline of actions, Map of initiatives and university networks, thematic glossaries, and bibliometric studies on the subject.

VII JORNADA DE MEDICINA DO CENTRO UNIVERSITÁRIO APARÍCIO CARVALHO – FIMCA (26, 27 e 28 DE OUTUBRO DE 2022)
Authors: FIMCA Revista 
Published: November 2023

As unidades de emergência consistem na parte central da execução do sistema de saúde. Assim, nota-se que esses serviços são essenciais no acolhimento ao paciente, o qual pode estar em um quadro grave e necessitar de atendimentos especializados. É válido abordar que, no Brasil, 90% das emergências são de casos clínicos e somente 10% estão relacionadas com traumas.
Em decorrência disso, verifica-se que a promoção de estudos a respeito do perfil das emergências clínicas, bem como a realização de eventos sobre os avanços terapêuticos e tecnológicos que viabilizem o acesso aos serviços de emergência hospitalar tornam-se primordiais ao manejo adequado. Dessa maneira, as principais áreas envolvidas nesses serviços incluem a Cardiologia, a Pediatria, a Ginecologia e Obstetrícia, a Neurologia, a Infectologia e a Nefrologia.
Nesse sentido, surgiu a proposta de se realizar um evento para todos os acadêmicos de medicina da FIMCA e região, visando explorar os fatores que envolvem o funcionamento de um serviço de emergência. Dessa forma, foram abordadas nos mais diversos campos para ampla divulgação de conhecimento, diversas especialidades, como: Neurologia, Nefrologia, Endocrinologia, Infectologia, Pediatria, Cardiologia. A VII Jornada de Medicina do Centro Universitário Aparício Carvalho foi realizada entre os dias 26 a 28 de outubro de 2022, com a participação de profissionais do campo em questão, os quais puderam debater com os alunos e apresentar as novidades da comunidade científica e também um pouco de suas vivências nesse campo da medicina.
O evento aconteceu dentro da instituição de ensino Centro Universitário Aparício Carvalho, organizado pela própria instituição, docentes e discentes presentes nela, resultando na elevação do engajamento do corpo docente, aumentando a participação do corpo discente com apresentações de trabalhos e outras atividades que enriqueceram a experiência da jornada. Ademais promoveu maior possibilidade de conhecimento entre os participantes com a interação dos profissionais especialistas com a plateia, evidenciando um excelente evento científico para que os alunos e futuros médicos se atualizassem sobre o tema emergências clínicas.
A Jornada acadêmica se fez exemplar para que os alunos pudessem começar a ter contato com eventos de nível superior e também com a escrita de conteúdos científicos. Além das palestras, minicursos e diversas oportunidades de enriquecimento do saber, a jornada também pôde contar com a divulgação de resumos científicos pelos alunos, que tiveram a oportunidade de apresentá-los e iniciar uma vivência no meio das publicações acadêmicas.
As publicações possibilitaram que os alunos tivessem uma nova visão sobre determinado tema do seu interesse relacionado à vasta área das ciências médicas, identificando novas oportunidades e discutindo outras formas para solucionar possíveis problemas, ampliando assim o senso crítico dos discentes.

Background. Earlier, on the translational model of alcoholic cardiomyopathy (ACMP) developed by us in outbred white rats, which reproduces the main clinical diagnostic signs of this disease, it was shown that in rats of both sexes under conditions of constant 24/7 alcoholization for 24 weeks, AСMP is formed.This study purpose is a comparative assessment of the features of the ACM formation in male and female rats depending on the level of ethanol consumption in model experiments simulating "domestic drunkenness" with periodic alcoholization 24/2 for 24 weeks.Materials and methods. Experiments were performed on outbred white rats randomized into 4 groups: group 1 — control male rats (n=18), group 2 — control female rats (n = 18), group 3 — alcoholized male rats (n = 39) and group 4 — alcoholized female rats (n = 19). Control animals received a normal diet and free access to water. Animals of the 3rd and 4th groups weekly, for 24 weeks, from Friday 22.00 to Monday 8.00, received a 10 % ethanol solution as the only source of liquid with unlimited access to standard food, and the usual diet on the remaining days.Results. In animals of both sexes, after 24 weeks from the consumption start of the ethanol solution, ACM is formed, as evidenced by an increase in the end-systolic and end-diastolic sizes of the left ventricle of the heart (p = 0.0001) and a decrease in its ejection fraction (p = 0.0001), while the degree of pathological myocardial remodeling is more pronounced in females. According to cluster analysis, by the consumption of ethanol (CET), animals of both sexes are divided into 3 subgroups: low, medium and high CET, however, in males, the subgroup with an average CET prevails — 56 %, and in females with a high CET — 47 % (p = 0.0286), the low CET subgroup is minimal (16 %). At the same time, if in males in all subgroups, starting from the 8th week of alcoholization, CET dynamically decreases, then how in females in subgroups with medium and high CET, starting from the 16th week, it increases. It was found that the degree of left ventricular remodeling in females with high and moderate CET was almost 2 times higher than in males (p < 0.05).Conclusion. In model experiments imitating “domestic drunkenness”, it was shown that in females the intensity of the left ventricle heart remodeling is signiﬁcantly higher than in males, which, apparently, is determined by the identiﬁed gender-dependent multidirectional trends in the formation of alcoholic behavior characterized by dynamic growth. consumption of ethanol in female rats as the duration of alcoholization increases.

Propagation Properties of Sunspots Umbral Oscillations in Horizontal and Vertical Directions
Authors: Wu Wei , Su Jiang-tao , Chen Jie , Zhu Xiao-shuai , Sych Robert 
Published: November 2023

Abstract
We present a study on investigating the propagation characteristics of umbral oscillations in sunspots. In sunspot 1 (located in NOAA AR 12127) with four umbrae, the analysis shows that the oscillations in different umbrae are correlated. The weak correlation (<20%) is attributed to the propagation of umbral oscillations across the umbral boundary to its adjacent umbra in the horizontal direction. We speculate that oscillations in two of the umbrae have a common origin in the sub-photosphere, resulting in a stronger correlation (>30%). Additionally, utilizing the TiO (photosphere), Hα (chromosphere) images provided by BBSO/GST, and the 304 Å (upper chromosphere and lower transition region), 171 Å (upper transition region), 193 Å (corona), and 211 Å (active region corona) images acquired by the Atmospheric Imaging Assembly on board the Solar Dynamics Observatory (SDO), we analyze the vertical propagation of oscillations in the sunspot umbra. Multi-channel observation shows that the umbral oscillations observed in the lower atmosphere of sunspot 1 cannot be detected in the upper atmosphere. However, in sunspot 2 (located in NOAA AR 12132), oscillations in the lower atmosphere can propagate to the upper atmosphere. Using photospheric magnetic field data provided by the Helioseismic and Magnetic Imager on board SDO, potential field extrapolation of the magnetic field for the two sunspots shows that open magnetic field structures allow sunspot oscillations to propagate to higher heights, while closed magnetic field structures do not.
Reconstruction of a Scale-dependent Gravitational Phase Transition
Authors: Farhang Marzieh , Khosravi Nima 
Published: November 2023

Abstract
In this work we extend our earlier phenomenological model for a gravitational phase transition and its generalization to early times by letting the modifications in the linearly perturbed Einstein equations be scale dependent. These modifications are characterized as deviations of the parameters μ(z, k) and γ(z, k) from their values in general relativity (GR). The scale-dependent amplitudes of modified μ(z, k) and γ(z, k) and the parameters defining the phase transition, along with the standard cosmological parameters, are measured by various data combinations. Out of the perturbation parameters, we construct gravity eigenmodes that represent patterns of perturbations best detectable by data. We detect no significant deviation from GR in these parameters. However, the larger parameter space produced due to the new degrees of freedom allows for the reconciliation of various data sets that are in tension in ΛCDM. In particular, we find H
0 = 71.9 ± 9.2 from anisotropies of the cosmic microwave background as measured by Planck (and various measurements of the baryonic acoustic oscillations, in agreement with local Hubble measurements). We also find that the σ
8 tension between the measurements of the Dark Energy Survey and Planck is reduced to less than 1σ.

Abstract
We present James Webb Space Telescope (JWST) Near Infrared Spectrograph (NIRSpec) integral field spectroscopy of the nearby luminous infrared galaxy NGC 7469. We take advantage of the high spatial/spectral resolution and wavelength coverage of JWST/NIRSpec to study the 3.3 μm neutral polycyclic aromatic hydrocarbon (PAH) grain emission on ∼200 pc scales. A clear change in the average grain properties between the star-forming ring and the central AGN is found. Regions in the vicinity of the AGN, with [Ne iii]/[Ne ii] > 0.25, tend to have larger grain sizes and lower aliphatic-to-aromatic (3.4/3.3) ratios, indicating that smaller grains are preferentially removed by photodestruction in the vicinity of the AGN. PAH emission at the nucleus is weak and shows a low 11.3/3.3 PAH ratio. We find an overall suppression of the total PAH emission relative to the ionized gas in the central 1 kpc region of the AGN in NGC 7469 compared to what has been observed with Spitzer on 3 kpc scales. However, the fractional 3.3 μm–to–total PAH power is enhanced in the starburst ring, possibly due to a variety of physical effects on subkiloparsec scales, including recurrent fluorescence of small grains or multiple photon absorption by large grains. Finally, the IFU data show that while the 3.3 μm PAH-derived star formation rate (SFR) in the ring is 27% higher than that inferred from the [Ne ii] and [Ne iii] emission lines, the integrated SFR derived from the 3.3 μm feature would be underestimated by a factor of 2 due to the deficit of PAHs around the AGN, as might occur if a composite system like NGC 7469 were to be observed at high redshift.
Production of 44Ti and Iron-group Nuclei in the Ejecta of 3D Neutrino-driven Supernovae
Authors: Sieverding Andre , Kresse Daniel , Janka Hans-Thomas 
Published: November 2023

Abstract
The radioactive isotopes 44Ti and 56Ni are important products of explosive nucleosynthesis, which play a key role in supernova (SN) diagnostics and have been detected in several nearby young SN remnants. However, most SN models based on nonrotating single stars predict yields of 44Ti that are much lower than the values inferred from observations. We present, for the first time, the nucleosynthesis yields from a self-consistent three-dimensional SN simulation of a ∼19 M
⊙ progenitor star that reaches an explosion energy comparable to that of SN 1987A and that covers the evolution of the neutrino-driven explosion until more than 7 s after core bounce. We find a significant enhancement of the Ti/Fe yield compared to recent spherically symmetric (1D) models and demonstrate that the long-time evolution is crucial to understanding the efficient production of 44Ti due to the nonmonotonic temperature and density history of the ejected material. Additionally, we identify characteristic signatures of the nucleosynthesis in proton-rich ejecta, in particular high yields of 45Sc and 64Zn.
Tilted Dark Halos Are Common and Long-lived, and Can Warp Galactic Disks
Authors: Han Jiwon Jesse , Semenov Vadim , Conroy Charlie , Hernquist Lars 
Published: November 2023

Abstract
In the Lambda cold dark matter paradigm, the dark halo governs the gravitational potential within which a galaxy can form and evolve. In this Letter we show that the present-day inner (r < 50 kpc) dark halo can be significantly misaligned with the stellar disk. To this end, we use the TNG50 run from the cosmological magnetohydrodynamic IllustrisTNG simulation suite. Such “tilted” dark halos can arise from a variety of processes including major mergers, massive flybys, or interactions with satellite companions. Furthermore, we show that tilted dark halos (1) are well traced by tilted stellar halos, (2) can maintain their tilt for >5 Gyr in isolated evolution, and (3) can generate warps in the outer disks that are stable over many Gyr. A tilted dark halo holds clues to important events in the formation history of a galaxy, and could help explain the abundance of warped disks in galaxy observations, including the Milky Way.
Dwindling Surface Cooling of a Rotating Jovian Planet Leads to a Convection Zone That Grows to a Finite Depth
Authors: Hindman Bradley W. , Fuentes J. R. 
Published: November 2023

Abstract
Recent measurements of Jupiter's gravitational field (by Juno) and seismology of Saturn's rings (by Cassini) strongly suggest that both planets have a stably stratified core that still possesses a primordial gradient in the concentration of heavy elements. The existence of such a “diffusely” stratified core has been a surprise as it was long expected that the Jovian planets should be fully convective and hence fully mixed. A vigorous zone of convection, driven by surface cooling, forms at the surface and deepens through entrainment of fluid from underneath. In fact, it was believed that this convection zone should grow so rapidly that the entire planet would be consumed in less than a million years. Here we suggest that two processes, acting in concert, present a solution to this puzzle. All of the giant planets are rapidly rotating and have a cooling rate that declines with time. Both of these effects reduce the rate of fluid entrainment into the convection zone. Through the use of an analytic prescription of entrainment in giant planets, we demonstrate that these two effects, rotation and dwindling surface cooling, result in a convection zone that initially grows but eventually stalls. The depth to which the convective interface asymptotes depends on the rotation rate and on the stratification of the stable interior. Conversely, in a nonrotating planet, or in a planet that maintains a higher level of cooling than current models suggest, the convection zone deepens forever, eventually spanning the entire planet.
