O tratamento cirúrgico da catarata desempenha um papel crucial na restauração da visão, sendo uma intervenção primordial para remover o cristalino opacificado. É fundamental explorar as diversas técnicas cirúrgicas modernas disponíveis para o tratamento da catarata, destacando suas vantagens e resultados. Ao examinar as diferentes abordagens cirúrgicas, busca-se oferecer uma visão abrangente das opções disponíveis aos oftalmologistas, considerando aspectos como segurança, eficácia visual e recuperação pós-operatória.
A escolha da técnica cirúrgica no tratamento da catarata é uma decisão importante, influenciada por fatores como a gravidade da opacificação do cristalino, a saúde ocular geral do paciente e suas preferências individuais. Nesse contexto, técnicas como facoemulsificação e cirurgia extracapsular serão avaliadas, destacando suas indicações específicas e comparando os resultados visuais e funcionais. Compreender as nuances de cada técnica é essencial para otimizar os resultados cirúrgicos e proporcionar uma melhor qualidade de vida aos pacientes afetados por essa condição oftalmológica.
Além disso, a avaliação dos resultados associados à cirurgia de catarata, incluindo aspectos como acuidade visual pós-operatória, taxa de complicações e satisfação do paciente, é crucial para avaliar a eficácia dos procedimentos e orientar as decisões clínicas. Uma análise crítica desses resultados permitirá uma compreensão mais aprofundada das implicações de cada abordagem cirúrgica, contribuindo para uma prática oftalmológica baseada em evidências e centrada no paciente.
Em última análise, este artigo busca consolidar informações atualizadas sobre as técnicas cirúrgicas modernas no tratamento da catarata, apresentando uma revisão crítica da literatura disponível. Ao fazer isso, visa-se promover o avanço contínuo da prática cirúrgica oftalmológica, melhorando os resultados visuais e funcionais e aprimorando a qualidade de vida dos pacientes submetidos à intervenção cirúrgica para catarata.

Com a busca por um sorriso mais estético, o clareamento dental é um dos procedimentos estético mais procurados nos consultórios odontológicos. Quando bem indicado, a eficácia e a segurança da técnica na maioria dos casos trazem grande satisfação ao paciente. Um efeito adverso muito comum a esse tratamento é a sensibilidade dental, que pode se agravar e chegar a alterações pulpares. O uso desses produtos sem orientação profissional pode causar danos irreversíveis às estruturas dentárias, levando a complicações como necrose pulpar e até mesmo perda dentária. O objetivo desse estudo foi relatar o caso clínico, dos elementos 21 e 22, necrosados, com imagens radiográficas de lesões perirradiculares. A paciente relatou que em busca de clarear mais seus dentes, passou realizar o procedimento de clareamento dental caseiro de forma indiscriminada. Traçado o plano de tratamento, o tratamento endodôntico foi realizado nos dois dentes em múltiplas sessões, com colocação de medicação intracanal a base de hidróxido de cálcio e, após o fim da sintomatologia, os dentes foram obturados com cones de guta-percha e cimento a base de óxido de zinco e eugenol. Concluiu-se que, o tratamento endodôntico reverteu o quadro sintomatológico, restabelecendo a função e a saúde dos elementos.

rot = 1.086 ± 0.003 days) and is not an integer harmonic nor alias of the orbital period, supporting the planetary nature of the observed periodicity. HS Psc b joins a small population of young, close-in giant planet candidates with robust age and mass constraints and demonstrates that giant planets can either migrate to their close-in orbital separations by 130 Myr or form in situ. Given its membership in a young moving group, HS Psc represents an excellent target for follow-up observations to characterize this young hot Jupiter further, refine its orbital properties, and search for additional planets in the system.
Detection of Contact Binary Candidates Observed By TESS Using the Autoencoder Neural Network
Authors: Ding Xu , Song ZhiMing , Wang ChuanJun , Ji KaiFan 
Published: April 2024

Abstract
A contact binary may be the progenitor of a red nova that eventually produces a merger event and have a cut-off period of around 0.2 days. Therefore, a large number of contact binaries is needed to search for the progenitor of red novae and to study the characteristics of short-period contact binaries. In this paper, we employ the Phoebe program to generate a large number of light curves based on the fundamental parameters of contact binaries. Using these light curves as samples, an autoencoder model is trained, which can reconstruct the light curves of contact binaries very well. When the error between the output light curve from the model and the input light curve is large, it may be due to other types of variable stars. The goodness of fit (R
2) between the output light curve from the model and the input light curve is calculated. Based on the thresholds for global goodness of fit (R
2), period, range magnitude, and local goodness of fit (R
2), a total of 1322 target candidates were obtained.
A Linear Model for Inertial Modes in a Differentially Rotating Sun

Published: April 2024

Abstract
Inertial wave modes in the Sun are of interest owing to their potential to reveal new insight into the solar interior. These predominantly retrograde-propagating modes in the solar subsurface appear to deviate from the thin-shell Rossby–Haurwitz model at high azimuthal orders. We present new measurements of sectoral inertial modes at m > 15 where the modes appear to become progressively less retrograde compared to the canonical Rossby–Haurwitz dispersion relation in a corotating frame. We use a spectral eigenvalue solver to compute the spectrum of solar inertial modes in the presence of differential rotation. Focussing specifically on equatorial Rossby modes, we find that the numerically obtained mode frequencies lie along distinct ridges, one of which lies strikingly close to the observed mode frequencies in the Sun. We also find that the n = 0 ridge is deflected strongly in the retrograde direction. This suggests that the solar measurements may not correspond to the fundamental n = 0 Rossby–Haurwitz solutions as was initially suspected, but to those for a higher n. The numerically obtained eigenfunctions also appear to sit deep within the convection zone—unlike those for the n = 0 modes—which differs substantially from solar measurements and complicates inference.
Formation of Limb-brightened Radio Jets by Angle-dependent Energy Extraction from Rapidly Rotating Black Holes

Published: April 2024

Abstract
Using general relativistic magnetohydrodynamic simulations, it has been suggested that the rotational energy of a rapidly rotating black hole (BH) is preferentially extracted along the magnetic field lines threading the event horizon in the middle and lower latitudes. Applying this angle-dependent Poynting flux to the jet downstream, we demonstrate that the jets exhibit limb-brightened structures at various viewing angles, as observed from Mrk 501, M87, and Cyg A between 5° and 75°, and that the limb brightening is enhanced when the jet is collimated strongly. It is also found that the jet width perpendicular to the propagation direction shrinks at the projected distance of the altitude where the jet collimates from a conical shape (near the BH) to a parabolic one (in the jet). Comparing with Very Long Baseline Interferometry observations, we show that this collimation takes place within the deprojected altitude of 100 Schwarzschild radii from the BH in the case of the M87 jet.
Trapped Water on Silicates in the Laboratory and in Astrophysical Environments
Authors: Potapov Alexey , Jäger Cornelia , Mutschke Harald , Henning Thomas 
Published: April 2024

Abstract
The existence of strongly bound water molecules on silicate surfaces, above the desorption temperature of water ice, was first predicted by computational studies and has recently been demonstrated by laboratory experiments. Such trapped water may be present in various astrophysical environments and there is now evidence for its presence in the diffuse interstellar medium (ISM) and in extraterrestrial particles. We present here new results of a laboratory study of the phenomenon of trapping (strong bonding) of water molecules by silicates. We show that the efficiency of the trapping is strongly dependent on the properties and composition of the surface. Our results point out that the presence of trapped water should be due to the hydrophilic properties of the silicate surface and that the nature of the trapping is physical (physisorption rather than chemisorption). We demonstrate that water can be trapped on silicates up to temperatures of about 470 K, which speaks for the presence of wet silicate grains in the terrestrial planet formation zone in planet-forming disks. Studying the thermal and UV stability of trapped water, we conclude that the detection of trapped water in the diffuse ISM speaks for its efficient continuous formation. We discuss our results as relevant to fundamental scientific questions, such as the oxygen depletion problem, the origin of water on Earth, and the formation of rocky planets.
Insights into Neutron Star Equation of State by Machine Learning
Authors: Guo Ling-Jun , Xiong Jia-Ying , Ma Yao , Ma Yong-Liang 
Published: April 2024

Abstract
Due to its powerful capability and high efficiency in big data analysis, machine learning has been applied in various fields. We construct a neural network platform to constrain the behaviors of the equation of state of nuclear matter with respect to the properties of nuclear matter at saturation density and the properties of neutron stars. It is found that the neural network is able to give reasonable predictions of parameter space and provide new hints into the constraints of hadron interactions. As a specific example, we take the relativistic mean field approximation in a widely accepted Walecka-type model to illustrate the feasibility and efficiency of the platform. The results show that the neural network can indeed estimate the parameters of the model at a certain precision such that both the properties of nuclear matter around saturation density and global properties of neutron stars can be saturated. The optimization of the present modularly designed neural network and extension to other effective models is straightforward.

Published: April 2024

Abstract
Seven rotational and fine-structure transitions of the deuterated molecular ion SD+ in the X
3Σ− ground electronic state have been measured in the 271–863 GHz region in the laboratory. This ion has been produced by direct-current glow discharge using a mixture of D2S and argon in a free space cell in a temperature range of −140°C to −160°C. The rotational, centrifugal distortion, spin–spin interaction, and hyperfine constants have been determined; the standard deviation of the residuals in the fitting is 109 kHz. The set of obtained spectroscopic parameters provides a list of accurate submillimeter rest frequencies of SD+ for astronomical detection. We have investigated lines of SD+ toward the quasar PKS 1830-211 using the Atacama Large Millimeter/submillimeter Array archive, as the z = 0.89 molecular absorber exists in front of this quasar. A data set covering the 297 GHz region includes the N

Published: April 2024

Abstract
Based on high-resolution measurements from the Magnetospheric Multiscale mission from 2015 May to 2018 June, we statistically investigate the properties of small-scale field-aligned currents (SFACs) in the magnetopause boundary layer. A total of 2235 SFACs are successfully identified. The durations of SFACs mainly fall between 0.2 and 0.3 s. Over 90% of SFACs have a width of less than 1 ion inertia length and are primarily distributed from 5 to 25 electron inertia lengths, implying that the SFACs belong to the kinetic-scale current layer. The main carriers of SFACs are electrons, and over 70% of SFACs exhibit net energy dissipation (i.e.,
J
·
E
′ > 0) with the majority of energy dissipation taking place in the parallel direction. SFACs are widely distributed spatially, and the occurrence rate of SFACs is higher in the boundary layer closer to the magnetosphere. Additionally, less than half of the total SFACs are identified in well-known structures, including the magnetic reconnection region, flux transfer event, Kelvin–Helmholtz vortex, and exhaust region, and 54% of the SFACs are in the “others” unknown structures. These results improve our comprehension of the current system at the magnetopause and the roles of SFACs in the coupling between the solar wind and magnetosphere.

La raison depuis Freud et le réel de la guerre
Authors: Laurent Éric 
Published: April 2024

Le titre de l’article de mon contradicteur condense deux titres de Kant. Au long de son texte il reproche d’accorder trop de crédit aux vaticinations de Cioran, demande des preuves académiques, s’autorise de Hannah Arendt. Je lui réponds que Kant c’est très bien, à condition d’y ajouter Sade. Et que seul cet ajout permet de définir la raison après Freud. Il pense aussi que Lacan parle de « pouvoir capitaliste » au sens marxiste du terme. C’est une erreur. Il y a peu de marxisme dans l’emploi de Lacan de ce terme. Enfin, je prends une distance avec les idéaux pacifistes qu’il pose comme un impératif kantien. Aux projets de paix perpétuelle, je préfère les équilibres calculés et précaires, inspirés par sentiment du réel de la guerre et l’angoisse devant ses conséquences.
Les mobilisations de parents d’élèves séquano-dyonisiens en faveur de l’égalité territoriale
Authors: Roux Félicie 
Published: April 2024

En abordant de façon systématique la dimension spatiale des pratiques protestataires sous différents aspects – conditions sociales d’émergence, revendications, répertoire d’actions –, cet article montre comment l’espace, dans ses composantes matérielle et symbolique, constitue un ressort de politisation important. Dans un premier temps, l’article examine les effets du contexte résidentiel sur la formation de collectifs socialement différenciés dans deux micro-espaces de la ville en prêtant attention aux trajectoires individuelles tout autant qu’aux interactions et pratiques dans l’espace de vie des mères (et pères) mobilisé·es. Or, si ces groupes ont des intérêts sociaux fortement contrastés, ils convergent pourtant autour d’un mot d’ordre militant, l’égalité territoriale. Dans un deuxième temps, l’article interroge ainsi les modalités d’appropriation de ce mot d’ordre en examinant les résonances discursives entre discours militants et catégories de l’action publique, et les formes de circulation et d’appropriation de ces catégories dans l’espace local. Enfin, la fédération et l’alliance de ces collectifs au niveau départemental, revendiquant « l’égalité 93 », conduisent à des tensions ou distances entre groupes sociaux localisés. Ainsi, si les catégorisations spatiales du monde social permettent la politisation et l’accès de groupes dominés à l’espace public et politique, elles contribuent aussi à construire la légitimité et l’autorité des groupes dominants dans l’espace local.
Prognostic Significance of Lymph Node Ratio in Predicting the Outcome of Oral Squamous Cell Carcinoma – A Retrospective Study
Authors: Sansgiri Tanvy Subir , Saluja Harish , Shah Seemit , Dadhich Anuj , Singh Deepak 
Published: April 2024

Abstract

Introduction:
The lymph node status is a very important prognostic factor in head-and-neck cancer. The presence of metastatic lymph nodes will reduce the overall survival by 50%. Lymph node ratio (LNR) is defined as the ratio of the number of positive lymph nodes to the total number of lymph nodes dissected. The aim of the study was to investigate the prognostic value of LNR in oral squamous cell carcinoma (OSCC).

Materials and Methods:
Medical records of pathologically confirmed OSCC patients who reported with loco-regional recurrence from January 2017 to January 2022 were analysed. LNR and disease-free survival (DFS) were calculated for each patient. The endpoint of the study was disease-free survival. Spearman’s correlation was used to establish a correlation between DFS and LNR.

Results:
A total of 33 patients were included in the study. DFS was calculated for all the patients. LNR was calculated in patients with pathological N+ neck. There was a negative significant moderate correlation between LNR and DFS (Spearman’s rho = −0.593, P < 0.001). A higher LNR value of more than 0.01 was associated with a shorter DFS period. T4 tumour stage had significantly higher LNR. A positive significant moderate correlation was found between LNR and tumour stage (Spearman’s rho = 0.703, P = 0.01). As the T stage increased, the LNR ratio also increased. In the present study, tumour subsite tongue was associated with significantly higher LNR (P = 0.001).

Discussion:
LNR can be considered an independent prognostic parameter for DFS in OSCC patients with cervical lymph node metastasis.
Maternal and perinatal health indicators from 2019 to 2022: Data from the POGS Nationwide Statistics System

Published: April 2024

OBJECTIVES:
The objectives of this study were to present maternal and perinatal health indicators for the years 2019–2022.

METHODOLOGY:
This is a cross-sectional review that analyzed data on maternal and perinatal health indicators, generated from submissions of POGS-accredited hospitals (training and service) from January 2019 to December 2022. The data were compared to the national data obtained from official public documents published by the Philippine Statistics Authority in 2022 and 2023.

RESULTS:
The number of member hospitals has steadily increased over the years, and compliance rates have been consistently over 85%. The total number of registered cases and live births declined in 2020 and 2021, but has increased to prepandemic levels in 2022. The primary cesarean section (CS) rates remained above 20%, with the highest rate noted in 2021 (25.5%). The top three-most common indications for primary CS were dysfunctional labor, fetal distress, and malpresentation. Stillbirth, perinatal, and maternal mortality rates showed an increase from 2019 to 2022, with peak rates registered for the year 2021. The top five causes of maternal death are: medical complications, hemorrhage, hypertension, infection, and others (unspecified). The case fatality rate among pregnant patients with confirmed COVID-19 infection was 1.18%.

CONCLUSION:
From 2019 to 2021, there was a decline in the number of registered cases and live births, and an increase in the primary CS rates, maternal mortality ratio, perinatal death rates, and stillbirth rates. This may be explained by the prevailing social, health, and economic impact of the COVID-19 pandemic during these years.

In this work, we establish the optimal regularity for solutions to the fully nonlinear thin obstacle problem. In particular, we show the existence of an optimal exponent

\alpha_{F}

such that

u

is

C^{1,\alpha_F}

on either side of the obstacle. In order to do that, we prove the uniqueness of blow-ups at regular points, as well as an expansion for the solution there. Finally, we also prove that if the operator is rotationally invariant, then

\alpha_{F} \ge \frac{1}{2}

and the solution is always

Pozitivno razumevanje svobode v Cankarjevih <i>Hlapcih</i>
Authors: Šuler Galos Jasmina 
Published: April 2024

Cankar’s drama The Serfs (Hlapci) was written during the cultural struggle waged at the turn of the 19th and 20th centuries and contains otherwise rarely stated political theses that have had a profound influence on the formation of Slovenian collective memory. The key world of Slovenian culture, as conveyed through the Cankar's drama, serves to express the dynamic processes of modernization and points to the unformed liberal and socialist discourse at the time. This is why the work functions in Slovenian culture as a call to action, even to active resistance.
