Published: November 2023

O fibroma de celulas gigantes é um lesão relativamente rara, e que clinicamente é semelhante a outras hiperplasias que se apresentam na cavidade oral. Geralmente, apresenta-se como nódulo séssil ou pendiculado, de crescimento lento e assintomático com a superficie nódular de 0,5 a 1 cm de diametro. A pesquisa contou com a participação de um paciente do sexo masculino, com 71 anos, melanoderma, tabagista e etilista. Na história médica pregressa o paciente relatou que não possui comorbidades e doenças sistêmicas diagnosticadas, mas possui o hábito parafuncional de mordiscar a região da lesão a aproximadamente onze anos. A importância do diagnóstico além de avaliar as características clínicas e histopatológicas da lesão, também foi analisado tais características como a distribuição etária, predileção de gênero, localização e etiologia da lesão. Este trabalho tem por objetivo relatar o caso de um fibroma de células gigantes em um paciente do sexo masculino com idade avançada, com a remoção excisional da lesão, que se encontra localizada próximo a comissura do lábio inferior esquerdo, e envio da amostra para realização do exame anatomopatológico.
Giant cell fibroma is a relatively rare lesion, which is clinically similar to other hyperplasias that occur in the oral cavity. It usually presents as a slow-growing, asymptomatic sessile or pedunculate nodule with a nodular surface of 0.5 to 1 cm in diameter. The research included the participation of a male patient, 71 years old, who was a smoker and an alcoholic. In the previous medical history, the patient reported that he does not have comorbidities and systemic diseases diagnosed but has had the parafunctional habit of nibbling the region of the lesion for approximately eleven years. The importance of diagnosis in addition to evaluating the clinical and histopathological characteristics of the lesion, was also analyzed such characteristics as age distribution, gender predilection, location, and etiology of the lesion. The objective of this study is to report the case of a giant cell fibroma in an elderly male patient, with an excisional removal of the lesion located near the commissure of the left lower lip and sending the sample for an anatomopathological examination.
The Advantages of Global Photometric Models in Fitting Transit Variations
Authors: Judkovsky Yair , Ofir Aviv , Aharonson Oded 
Published: November 2023

Abstract
Estimation of planetary orbital and physical parameters from light-curve data relies heavily on the accurate interpretation of Transit Timing Variation (TTV) measurements. In this letter, we review the process of TTV measurement and compare two fitting paradigms—one that relies on making transit-by-transit timing estimates and then fitting a TTV model to the observed timings, and one that relies on fitting a global flux model to the entire light-curve data set simultaneously. The latter method is achieved either by solving for the underlying planetary motion (often referred to as “photodynamics”), or by using an approximate or empirical shape of the TTV signal. We show that, across a large range of the transit S/N regime, the probability distribution function of the mid-transit time significantly deviates from a Gaussian, even if the flux errors do distribute normally. Treating the timing uncertainties as if they are distributed normally leads, in such a case, to a wrong interpretation of the TTV measurements. We illustrate these points using numerical experiments and conclude that a fitting process that relies on a global flux fitting, rather than the derived TTVs, should be preferred.
Bound Debris Expulsion from Neutron Star Merger Remnants

Published: November 2023

Abstract
Many studies have found that neutron star mergers leave a fraction of the stars’ mass in bound orbits surrounding the resulting massive neutron star or black hole. This mass is a site of r-process nucleosynthesis and can generate a wind that contributes to a kilonova. However, comparatively little is known about the dynamics determining its mass or initial structure. Here we begin to investigate these questions, starting with the origin of the disk mass. Using tracer particle as well as discretized fluid data from numerical simulations, we identify where in the neutron stars the debris came from, the paths it takes in order to escape from the neutron stars’ interiors, and the times and locations at which its orbital properties diverge from those of neighboring fluid elements that end up remaining in the merged neutron star.
Spectro-polarimetric Properties of Sunquake Sources in X1.5 Flare and Evidence for Electron and Proton Beam Impacts
Authors: Kosovichev Alexander G. , Sadykov Viacheslav M. , Stefan John T. 
Published: November 2023

Abstract
The first significant sunquake event of Solar Cycle 25 was observed during the X1.5 flare of 2022 May 10, by the Helioseismic and Magnetic Imager (HMI) on board the Solar Dynamics Observatory. We perform a detailed spectro-polarimetric analysis of the sunquake photospheric sources, using the Stokes profiles of the Fe i 6173 Å line, reconstructed from the HMI linear and circular polarized filtergrams. The results show fast variations of the continuum emission with rapid growth and slower decay lasting 3–4 minutes, coinciding in time with the hard X-ray impulses observed by the Konus instrument on board the Wind spacecraft. The variations in the line core appeared slightly ahead of the variations in the line wings, showing that the heating started in the higher atmospheric layers and propagated downward. The most significant feature of the line profile variations is the transient emission in the line core in three of the four sources, indicating intense, impulsive heating in the lower chromosphere and photosphere. In addition, the observed variations of the Stokes profiles reflect transient and permanent changes in the magnetic field strength and geometry in the sunquake sources. Comparison with the radiative hydrodynamics models shows that the physical processes in the impulsive flare phase are substantially more complex than those predicted by proton and electron beam flare models currently presented in the literature.
Using a Quench Level Approximation to Estimate the Effect of Metallicity on the Abundances of N-bearing Species in H2-dominated Atmospheres
Authors: Soni Vikas , Acharyya Kinsuk 
Published: November 2023

Abstract
Variations in atmospheric elemental nitrogen can considerably affect the abundance of major nitrogen-bearing species such as NH3 and HCN. Also, due to vertical mixing and photochemistry, their abundance deviates from thermochemical equilibrium. The goal of this study is to understand the effect of atmospheric metallicity on the composition of NH3, N2, and HCN over a large parameter space in the presence of vertical mixing, which when combined with the work on CHO-bearing species in Soni & Acharyya can provide a comprehensive understanding of the effect of atmospheric metallicity. We used quenching approximations and a full chemical kinetics model for the calculations, and a comparison between these two methods was made. To generate thermal profiles, the petitRADTRANS code was used. Chemical timescales of NH3 and N2 are found to be complex functions of metallicity, while HCN is inversely proportional. Using quenched abundances of NH3 and CO, the quenched abundance of HCN can be constrained since it remains in equilibrium with NH3, CO, and H2O. Quenched NH3 increases with increasing K

equi; the parameter space moves toward a lower equilibrium temperature, and the abundance of HCN increases with metallicity. Finally, we used a data set of quenched abundances to provide a list of potential candidates in which the observation of HCN is possible.
A Simple Method for Predicting N
H Variability in Active Galactic Nuclei

Published: November 2023

Abstract
The unified model of active galactic nuclei (AGNs) includes a geometrically thick obscuring medium to explain the differences between type I and type II AGNs as an effect of inclination angle. This medium is often referred to as the torus and is thought to be “clumpy” as the line-of-sight column density, N
H, has been observed to vary in time for many sources. We present a method which uses a variation in the hardness ratio to predict whether an AGN has experienced N
H variability across different observations. We define two sets of hard and soft bands that are chosen to be sensitive to the energies most affected by changes in N
H. We calculate hardness ratios for Chandra and XMM-Newton observations of a sample of 12 sources with multiple observations, and compare the predictions of this method to the N
H values obtained from spectral fitting with physically motivated torus models (borus02, MYTorus, and UXCLUMPY). We also provide a calibrated correction factor that allows comparison between Chandra and XMM-Newton observations which is otherwise not possible due to differences in the instrument response functions. The sensitivity of this method can be easily adjusted. As we decrease the sensitivity, we find that the false positive rate becomes small while the true positive rate remains above 0.5. We also test the method on simulated data and show that it remains reliable for observations with as few as 100 counts. Therefore, we conclude that the method proposed in this work is effective in preselecting sources for variability studies.

Abstract
During the outbursts of black hole X-ray binaries (BHXRBs), their accretion flows transition through several states. The source luminosity rises in the hard state, dominated by nonthermal emission, before transitioning to the blackbody-dominated soft state. As the luminosity decreases, the source transitions back into the hard state and fades to quiescence. This picture does not always hold, as ≈40% of the outbursts never leave the hard state. Identifying the physics that govern state transitions remains one of the outstanding open questions in black hole astrophysics. In this paper we present an analysis of archival RXTE data of multiple outbursts of GX 339−4. We compare the properties of the X-ray variability and time-averaged energy spectrum and demonstrate that the variability (quantified by the power spectral hue) systematically evolves ≈10–40 days ahead of the canonical state transition (quantified by a change in spectral hardness); no such evolution is found in hard-state-only outbursts. This indicates that the X-ray variability can be used to predict if and when the hard-to-soft state transition will occur. Finally, we find a similar behavior in 10 outbursts of four additional BHXRBs with more sparse observational coverage. Based on these findings, we suggest that state transitions in BHXRBs might be driven by a change in the turbulence in the outer regions of the disk, leading to a dramatic change in variability. This change is only seen in the spectrum days to weeks later, as the fluctuations propagate inwards toward the corona.
