Electromagnetic properties of heavy mesons in heavy quark limit [PDF]
Phys.Lett.B516:65-71,2001, 2001 The electromagnetic (EM) form fators of the pseudoscalar and vector mesons are calculated in the light-front framework. We extract these form factors from the relevant matrix elements directly, instead of choosing the Breit frame. The results show that the charge radius of the meson are related to both the first and second longitudinal momentum square ...

Fatores de risco para histerectomia em mulheres brasileiras [PDF]
Cadernos de Saúde Pública, 2003 Realizou-se um estudo de caso-controle exploratório para investigar fatores de risco para histerectomia entre usuárias do setor público de saúde em Recife, Pernambuco, Brasil. Os 373 casos são mulheres com idade entre 30 e 54 anos, submetidas à histerectomia eletiva por condição pélvica benigna.

Hygienisation, Gentrification, and Urban Displacement in Brazil
Antipode, Volume 52, Issue 1, Page 124-144, January 2020., 2020 Abstract This article engages recent debates over gentrification and urban displacement in the global South. While researchers increasingly suggest that gentrification is becoming widespread in “Southern” cities, others argue that such analyses overlook important differences in empirical context and privilege EuroAmerican theoretical frameworks.

Predição de Incidência de Lesão por Pressão em Pacientes de UTI usando Aprendizado de Máquina [PDF]
arXiv, 2021 Pressure ulcers have high prevalence in ICU patients but are preventable if identified in initial stages. In practice, the Braden scale is used to classify high-risk patients. This paper investigates the use of machine learning in electronic health records data for this task, by using data available in MIMIC-III v1.4. Two main contributions are made: a

New AdS$_3$/CFT$_2$ pairs in massive IIA with $(0,4)$ and $(4,4)$ supersymmetries [PDF]
, 2022 We construct a new class of $\text{AdS}_3\times $S$^3\times $M$_4$ solutions of massive Type IIA supergravity with $(0,4)$ supersymmetries and SU(3) structure. We study in detail two subclasses of these solutions. The first subclass is when M$_4=$S$^2\times \Sigma_2$, with $\Sigma_2$ a 2d Riemann surface, and the geometry is foliated over the $\Sigma_2$

Line defects as brane boxes in Gaiotto-Maldacena geometries [PDF]
, 2022 We construct a new family of $\text{AdS}_2\times S^2\times S^2$ solutions to Type IIA supergravity with 4 supercharges acting with non-Abelian T-duality on the recent class constructed in arXiv:2107.12277. We focus on a particular solution in this class asymptoting locally to an $\text{AdS}_5$ Gaiotto-Maldacena geometry. This solution allows for a line

DNA damage in children and adolescents with cardiovascular disease risk factors [PDF]
, 2012 The risk of developing cardiovascular disease (CVD) is related to lifestyle (e.g. diet, physical activity and smoking) as well as to genetic factors.

Detection of a strong ~2.5 Hz modulation in the Newly Discovered Millisecond Pulsar MAXI J1816-195 [PDF]
, 2023 MAXI J181-195 is a newly discovered accreting millisecond X-ray pulsar that went outburst in June 2022. Through timing analysis with NICER and NuSTAR observations, we find a transient modulation at ~2.5 Hz during the decay period of MAXI J1816-195.

CÂNCER GÁSTRICO: FATORES DE RISCO
Revista Ibero-Americana de Humanidades, Ciências e EducaçãoO câncer gástrico, apesar de sua incidência ter diminuído em várias partes do mundo, continua a ser uma das principais causas de morte por câncer, especialmente em países onde a doença ainda é prevalente.
