Published: February 2022

Abstract
Observational precursors of large solar flares provide a basis for future operational systems for forecasting. Here, we study the evolution of the normalized emergence (EM), shearing (SH), and total (T) magnetic helicity flux components for 14 flaring (with at least one X-class flare) and 14 nonflaring (<M5-class flares) active regions (ARs) using the Space-weather Helioseismic Magnetic Imager Active Region Patches vector magnetic field data. Each of the selected ARs contain a δ-type spot. The three helicity components of these ARs were analyzed using wavelet analysis. Localized peaks of the wavelet power spectrum (WPS) were identified and statistically investigated. We find that (i) the probability density function of the identified WPS peaks for all the EM/SH/T profiles can be fitted with a set of Gaussian functions centered at distinct periods between ∼3 and 20 hr. (ii) There is a noticeable difference in the distribution of periods found in the EM profiles between the flaring and nonflaring ARs, while no significant difference is found in the SH and T profiles. (iii) In flaring ARs, the distributions of the shorter EM/SH/T periods (<10 hr) split up into two groups after flares, while the longer periods (>10 hr) do not change. (iv) When the EM periodicity does not contain harmonics, the ARs do not host a large energetic flare. (v) Finally, significant power at long periods (∼20 hr) in the T and EM components may serve as a precursor for large energetic flares.

Abstract
As a transient X-ray binary, MAXI J1659-152 contains a black hole candidate as its compact star. MAXI J1659-152 was discovered on 2010 September 25 during its only known outburst. Previously published studies of this outburst indicate that MAXI J1659-152 may have an extreme retrograde spin, which, if confirmed, would provide an important clue as to the origin of black hole spin. In this paper, utilizing updated dynamical binary system parameters (i.e., the black hole mass, the orbital inclination, and the source distance) provided by Torres et al., we analyze 65 spectra of MAXI J1659-152 from RXTE/PCA, in order to assess the spin parameter. With a final selection of nine spectra matching our f
sc ≲ 25%, soft state criteria, we apply a relativistic thin disk spectroscopic model kerrbb2 over 3.0–45.0 keV. We find that inclination angle correlates inversely with spin, and, considering the possible values for inclination angle, we constrain spin to be −1 < a
* ≲ 0.44 at a 90% confidence interval via X-ray continuum fitting. We can only rule out an extreme prograde (positive) spin. We confirm that an extreme retrograde solution is possible and is not ruled out by considering accretion torques given the young age of the system.
Evolution of Highly Magnetic White Dwarfs by Field Decay and Cooling: Theory and Simulations
Authors: Bhattacharya Mukul , Hackett Alexander J. , Gupta Abhay , Tout Christopher A. , Mukhopadhyay Banibrata 
Published: February 2022

Abstract
We investigate the luminosity suppression and its effect on the mass–radius relation and cooling evolution of highly magnetized white dwarfs. Based on the effect of magnetic field relative to gravitational energy, we suitably modify our treatment of the radiative opacity, magnetostatic equilibrium, and degenerate core equation of state to obtain the structural properties of these stars. Although the Chandrasekhar mass limit is retained in the absence of magnetic field and irrespective of the luminosity, strong central fields of about 1014 G can yield super-Chandrasekhar white dwarfs with masses ∼2.0 M
⊙. Smaller white dwarfs tend to remain super-Chandrasekhar for sufficiently strong central fields even when their luminosity is significantly suppressed to 10−16
L
⊙. Nevertheless, owing to the cooling evolution and simultaneous field decay over 10 Gyr, the limiting masses of small magnetized white dwarfs can fall to 1.5 M
⊙ over time. However, the majority of these systems still remain practically hidden throughout their cooling evolution because of their high fields and correspondingly low luminosities. Utilizing the stellar evolution code stars, we obtain close agreement with the analytical mass limit estimates, which suggests that our analytical formalism is physically motivated. Our results argue that super-Chandrasekhar white dwarfs born as a result of strong-field effects may not remain so forever. This explains their apparent scarcity, in addition to making them hard to detect because of their suppressed luminosities.

Published: February 2022

Background and Objectives: Myeloproliferative neoplasms (MPNs) are Philadelphia negative disorders involving polycythemia vera (PV), essential thrombocythemia (ET), primary myelofibrosis (PMF). Although JAK2 mutation is almost involved, other several mutations are linked to MPNs risk and prognosis. TNFAIP3 genetic mutations are related to several cancers and autoimmune diseases. Our study aimed to demonstrate the effects of rs2230926_T/G & rs5029939_C/G SNVs of TNFAIP3 gene on the risk and prognosis of JAK2 V617F positive MPNs.
Methods: Matched 2 groups in age, sex and race were enrolled in our research; 80 MPNs cases group and 130 normal healthy controls group with follow up of MPNs cases for 3 years. Taqman assay probes involved in real time polymerase chain reaction (PCR) were utilized for variants analysis.
Results: The rs2230926 & rs5029939 SNVs were in modest linkage disequilibrium (LD) in MPNs cases. The observed frequencies of G allele and its genotypes of both variants were more prevalent in MPNs patients than normal controls. The bleeding symptoms and the presence of splenomegaly were more existent in the heterozygous genotype and the combined G involved genotypes respectively. The overall survival (OS) was lower in G containing genotypes of both variants but the progression free survival (PFS) was affected only in rs5029939 SNV.
Conclusion: Our study revealed the association of G containing genotypes of both rs2230926 & rs5029939 SNVs to the increased MPNs incidence as well to poor clinical course and prognosis of JAK2 V617F positive MPNs disorders in Egyptian ethnic.
La lutte contre la précarité alimentaire
Authors: Sèze Benjamin 
Published: February 2022

En décembre 2020, le Cocolupa, installé par le ministre des Solidarités et de la Santé, celui de l’Agriculture et de l’Alimentation et celle du Logement, s’est fixé un objectif ambitieux : transformer le modèle français de lutte contre la précarité alimentaire. Et pour cause, depuis le début de la pandémie de Covid-19, au printemps 2020, le nombre de personnes recourant à l’aide alimentaire a explosé, et les images de jeunes faisant la queue pour recevoir quelques boîtes de conserve et des paquets de pâtes ont choqué l’opinion publique.
Pascal, philosophe chrétien ?
Authors: Devillairs Laurence 
Published: February 2022

Nous fêterons prochainement l’anniversaire de la naissance de Blaise Pascal. Mais savons-nous exactement qui est cet auteur du Grand Siècle ? un chrétien ? un janséniste ? un moraliste ? un pourfendeur sombre et désespérant de la vanité et de la comédie humaines ? Si nous tentions de lire autrement les Pensées de Pascal pour y découvrir une philosophie ni tragique ni secondaire, ni convenue ni soumise, mais profondément originale et inclassable. Pascal n’appartient à aucune école, ni à aucune chapelle.
Les inégalités d’accès aux ressources par les réseaux personnels chez les patients atteints de cancer
Authors: Barthe Jean-François , Defossez Adrien 
Published: February 2022

La littérature scientifique a montré que certaines catégories de patients parvenaient moins que d’autres à accéder aux ressources produites par le système de soins, comme l’information de santé par exemple. Nous nous sommes demandé dans quelle mesure l’aide apportée par l’entourage relationnel au cours de la maladie n’est pas soumise elle aussi à de fortes disparités selon les patients. À partir d’une enquête en cours ayant permis l’analyse de 18 parcours de patients atteints de cancer, nous montrons que l’accès aux ressources par les réseaux personnels est très inégal : certains malades vont pouvoir compter sur un entourage leur procurant des ressources nombreuses et variées, quand d’autres vont se retrouver totalement démunis de ce point de vue. Les caractéristiques des réseaux personnels des malades sont décrites ainsi que les types de ressources fournis par l’entourage. L’entourage relationnel, loin de permettre une réduction des inégalités d’accès aux ressources entre patients, participerait au contraire à leur production.
La dimension spatiale de l’innovation dans les régions périphériques nordiques
Authors: Dubois Alexandre 
Published: February 2022

Cet article se propose d’explorer la dimension spatiale des problématiques contemporaines du développement régional dans les zones périphériques nordiques. Historiquement, le développement de ces régions s’est fait sur la base de l’exploitation des abondantes ressources naturelles disponibles, telles que les minerais (fer, cuivre…) ou le bois. Dans une première partie, l’article propose d’introduire un cadrage conceptuel permettant de mieux appréhender la complexité des systèmes de relations entretenues par les acteurs de ces régions. Dans une deuxième partie, l’exemple d’une PME d’une localité minière du Nord de la Suède est utilisé afin d’illustrer comment ce cadrage permet de comprendre les dimensions relationnelle et spatiale de ces processus. Enfin, dans la dernière partie, l’article propose de discuter les récents exemples venus de l’implémentation de la stratégie de la « spécialisation intelligente » permettant d’exposer les défis du développement territorial, notamment en ce qui concerne l’équilibre à trouver entre la gouvernance des ressources naturelles et l’inclusion de ces régions dans l’économie de la connaissance, au travers de la gouvernance territoriale.
La ville suédoise : le triomphe de l’oikos ?
Authors: Filler André 
Published: February 2022

Le présent article se propose de dégager des lignes d’évolution de la ville suédoise. Il interroge le particularisme du développement du tissu urbain suédois par rapport au contexte général d’urbanisme européen et scandinave. Après avoir souligné le rôle ambigu de l’agglomération suédoise, juridiquement et administrativement floue, spatialement poreuse par rapport aux zones non urbanisées de la commune, unité administrative en vigueur, sera identifiée la problématique : l’équilibre entre l’esthétique et le social dans la conception urbaine du royaume. Résultat d’urbanisme moderne ou post-moderne, illustration matérielle du modèle social-démocrate ou lieu de tensions et de fonctions atomisées, l’aménagement du territoire urbain en Suède est expliqué en convoquant la notion aristotélicienne d’oikos comme une transposition de la métaphore de « foyer », broyant de ce fait la frontière entre « dedans » et « dehors ».
La naturbanité, une utopie réalisée par le Parc national urbain de Stockholm ?
Authors: Girault Camille 
Published: February 2022

Au prisme du Parc national urbain de Stockholm, un renversement des logiques de protection est ici envisagé comme figure de l’utopie : l’urbain n’est pas appréhendé comme une menace vis-à-vis de la nature, l’urbanité est au contraire considérée comme l’objet même de la protection. En se revendiquant comme la première ville du monde à avoir établi un tel « Parc national urbain », Stockholm nourrit l’image d’une cité idéale par l’établissement d’un espace urbain innovant. Ce dernier participe à l’identité urbaine et contribue à la production d’un rapport nordique au monde où des valeurs a priori contradictoires sont condensées en un même lieu. L’imbrication forte entre l’urbanité et la naturalité qui en résulte invite ainsi à proposer et à discuter la notion de naturbanité comme le fondement et l’expression d’une utopie réalisée dans la métropole suédoise.

Published: February 2022

Introduction:
This study aimed to evaluate if single nucleotide polymorphisms (SNPs) in runt-related transcription factor 2 (RUNX2) and bone morphogenetic protein 2 (BMP2) are associated with different craniofacial patterns. Furthermore, we also investigated if RUNX2 and BMP2 expression in the maxilla and mandible are differently expressed according to facial phenotypes and influenced by the SNPs in their encoding genes. Orthognathic patients were included.

Materials and Methods:
Lateral cephalometric radiographs were used to classify facial phenotypes based on Steiner's ANB and Ricketts’ NBa-PtGn angles. Bone samples from 21 patients collected during orthognathic surgery were used for the gene expression assays. DNA from 129 patients was used for genotyping the SNPs rs59983488 and rs1200425 in RUNX2 and rs235768 and rs1005464 in BMP2. The established alpha was 5%.

Results:
A statistically significant difference was observed in the relative BMP2 expression in the mandible between Class I and III participants (P = 0.042). Homozygous GG (rs59983488) had higher RUNX2 expression (P = 0.036) in the mandible. In maxilla, GG (rs1200425) had a higher BMP2 expression (P = 0.038).

Discussion:
In conclusion, BMP2 is expressed differently in the mandible of Class I and Class III participants. Genetic polymorphisms in RUNX2 and BMP2 are associated with their relative gene expression.

Authors: Candido Isabella Romão , da Silva Carolina Silvano Vilarinho , Santos Garcia Eduardo dos , da Silva André Luís Fernandes , Fernandes Poleti Thais Maria Freire , Gialain Ivan Onone , Borba Alexandre Meireles 
Published: February 2022

Rationale:
Ameloblastoma often requires complex facial treatments such as resection and reconstruction, which can be aided using three-dimensional resources towards improved surgical planning, reduction of surgical time, and customization.

Patient Concerns:
A 51-year-old patient, concerned about submandibular volumetric increase discovered performing imaging exams to install dental implants.

Diagnosis and Treatment:
Diagnosed with ameloblastoma, he underwent uneventful partial mandibular resection and placement of prebent mandibular reconstruction plate. Four months later, following a motorcycle accident, a deflection of the plate and mandibular fracture was observed. Using the initial prototyping, a new reconstruction plate was customized and surgically placed to reduce the mandibular fracture, with adequate titanium plate adaptation to the remaining bone and maintenance of aesthetic mandibular contour.

Outcomes and Take-away Lessons:
The current digital dentistry resources, such as computed tomography and intraoral scan, can be recovered and used as a backup of recorded anatomy anytime in future, providing a long-lasting facial digital biobank.
¿Es momento de adoptar el DAPSA para la evaluación de la Artritis Psoriásica?
Authors: Soriano Enrique R. 
Published: February 2022

La mejor forma de evaluar la respuesta al tratamiento en artritis psoriásica no está aún definida. Importantes esfuerzos están siendo realizados por grupos como GRAPPA (Group for Research and Assessment of Psoriasis and Psoriatic Arthritis) y OMERACT (Outcome Measures in Rheumatology), para validar instrumentos para la medición de la actividad de esta enfermedad y para encontrar algún instrumento que evalúe la misma en forma global. Encontrar un solo instrumento que sea capaz de evaluar la enfermedad en sus principales y distintos dominios de compromiso (piel, articulaciones, compromiso axial, uñas, entesitis y dactilitis), es difícil, por la desconexión que muchas veces existe entre la actividad de los mismos.

A ETIOLOGIA SOCIOECONÔMICA DA CÁRIE DENTAL E A PROMOÇÃO DA SAÚDE BUCAL EM CRIANÇAS E ADOLESCENTES - ÊNFASE À CIDADE DE BELÉM – PA
Authors: Silva Eliane Paiva da 
Published: February 2022

O Brasil caracteriza-se como o país com maior quantidade de cirurgiões-dentistas no mundo, no entanto, as disparidades sócio-econômicas geram uma grande discrepância na distribuição dos serviços odontológicos, o que representa um dos fatores para alto índice CPOD na região Norte. Crianças e adolescentes representam grupos de risco para o desenvolvimento da cárie dental, especialmente em regiões onde há menos atendimento odontológico, e mesmo pouca demanda de atendimento por parte da população, muitas vezes devido à falta da educação em saúde bucal, para compreender a importância da visita à consultórios odontológicos periodicamente. A educação em saúde bucal, também consta como um método de prevenção primária contra a cárie dental, portanto deve ser promovida a população, em especial para crianças e adolescentes que vivem em áreas de difícil acesso à serviços odontológico. Nesse sentido, o objetiva-se neste paper o estudo de fatores socioeconômicos como etiologia da cárie dental, bem como ações de promoção bucal como prevenção e mitigação da cárie dental, com ênfase a região de Belém - PA no Brasil.
