Relación multifactorial involucrada en los procesos de crecimiento, facial. “Enfocada al lenguaje del Servosistema de Alexandre Petrovic”: Revisión de la literatura.

 The knowledge of being able to determine skeletal maturation and missing growth potential is an essential element when planning orthodontic treatment. The study of craniofacial growth and development is a complex and essential process for the diagnosis and resolution of malocclusions. Craniofacial growth and development occurs by the process of growth and ossification of the hyaline cartilage, thus promoting the theory of the servosystem, which is a system with feedback, of constant renewal, which generates a new response. From this point of view, Petrovic considers involving orthopedic appliances, where he explained that the mandibular condyle can respond to mechanical stimuli causing stress at the level of anatomical structures due to orthodontic forces through the interaction of blood circulation and cells white cells that as a result form bone remodeling, which could be inhibitory or synergistic. The objective of this review is to summarize recent concepts on craniofacial growth, focused on the theory of Alexandre Petrovic and his collaborators, with the development of general scientific knowledge and inspire the creation of a new, more integrated multidisciplinary approach based on the person, through bases of MEDLINE, EMBASE, Pubmed, and Google Scholar data, which were evaluated, and synthesized, to be part of the next literature review.   El conocimiento de poder determinar la maduración esquelética y el potencial de crecimiento faltante, es un elemento esencial a la hora de la planificación en el tratamiento ortodóncico. El estudio del crecimiento y desarrollo craneofacial resulta un proceso complejo e indispensable para el diagnóstico y resolución de maloclusiones. El crecimiento y desarrollo craneofacial sucede por el proceso de crecimiento y osificación del cartílago hialino, fomentando así la teoría del servosistema, el mismo que es un sistema con retroalimentación, de renovación constante, lo que genera una nueva respuesta. Desde este punto de vista, Petrovic considera involucrar la aparatología ortopédica, donde explicó que el cóndilo mandibular puede contestar a estímulos mecánicos ocasionando estrés a nivel de las estructuras anatómicas debido a las fuerzas ortodónticas por medio de la interactuación de la circulación de la sangre y células blancas que como resultado forman la remodelación ósea, lo que podría ser inhibitorio o sinérgico. El objetivo de esta revisión es resumir conceptos recientes sobre el crecimiento craneofacial, enfocados a la teoría de Alexandre Petrovic y sus colaboradores, con el desarrollo del conocimiento científico general e inspirar a crear un nuevo enfoque multidisciplinario más integrado basado en la persona, mediante bases de datos MEDLINE, EMBASE, Pubmed, y Google Académico, las cuales fueron evaluadas, y sintetizadas, para ser parte de la siguiente revisión de la literatura.   

Caninos impactados. Uma revisão da literatura moderna

La impactación de un órgano dentario es uno de los motivos estadísticamente más comunes en la práctica diaria y su resolución ortodóncica sigue siendo un reto para el Especialista, donde un canino ocupan el segundo lugar de los dientes impactados más frecuentes con una incidencia que oscila entre el 0,8% y el 5.9%, con una relación de 3:1 para la impactación palatina y vestibular y con una frecuencia 2 veces mayor en mujeres que en hombres. Se realizo una búsqueda en diversas bases de datos digitales como: Pubmed, SciencieDirect, Google Scholar, Scopus, Lilacs, Cochrane Library, Web of Science, Epistemonikos, Sage, ProQuest, y se restringió a artículos publicados desde el año 2018 hasta el 2023 sin límite de idiomas. Se aplicó la lista de verificación PRISMA, con la cual se obtuvieron y revisaron 30 artículos aptos para esta revisión. Finalmente, la literatura disponible revela que un diagnóstico preciso, una localización cuidadosa del canino impactado, una elección correcta del abordaje quirúrgico, una fijación estable y confiable del accesorio de ortodoncia, la dirección y magnitud correcta de la fuerza aplicada y un manejo conservador de los tejidos blandos conducen directamente al éxito del tratamiento.The impaction of a dental organ is one of the most statistically common reasons in daily practice and its orthodontic resolution continues to be a challenge for the Specialist, where a canine is in second place among the most frequently impacted teeth with an incidence that ranges between 0.8% and 2.1%, with a ratio of 3:1 for palatal and vestibular impaction and with a frequency 2 times higher in women than in men. A search was carried out in various digital databases such as: Pubmed, SciencieDirect, Google Scholar, Scopus, Lilacs, Cochrane Library, Web of Science, Epistemonikos, Sage, ProQuest, and was restricted to articles published from 2018 to 2023 without language limit. The PRISMA checklist was applied, with which 30 articles suitable for this review were obtained and reviewed. Finally, the available literature reveals that an accurate diagnosis, careful localization of the impacted canine, correct choice of surgical approach, stable and reliable fixation of the orthodontic accessory, correct direction and magnitude of the applied force and conservative management of soft tissues lead directly to treatment successA impactação de um órgão dentário é uma das razões mais comuns estatisticamente na prática diária e sua resolução ortodôntica continua sendo um desafio para o especialista, sendo o canino o segundo dente impactado mais comum, com uma incidência que varia de 0,8% a 5,9%, com uma proporção de 3:1 para impactação palatina e vestibular e com uma frequência 2 vezes maior em mulheres do que em homens.

Measurement of the double-differential inclusive jet cross section in proton-proton collisions at s\sqrt{s} = 5.02 TeV

International audienceThe inclusive jet cross section is measured as a function of jet transverse momentum $p_\mathrm{T}$ and rapidity $y$. The measurement is performed using proton-proton collision data at $\sqrt{s}$ = 5.02 TeV, recorded by the CMS experiment at the LHC, corresponding to an integrated luminosity of 27.4 pb$^{-1}$. The jets are reconstructed with the anti-$k_\mathrm{T}$ algorithm using a distance parameter of $R$ = 0.4, within the rapidity interval $\lvert y\rvert$$\lt$ 2, and across the kinematic range 0.06 $\lt$$p_\mathrm{T}$$\lt$ 1 TeV. The jet cross section is unfolded from detector to particle level using the determined jet response and resolution. The results are compared to predictions of perturbative quantum chromodynamics, calculated at both next-to-leading order and next-to-next-to-leading order. The predictions are corrected for nonperturbative effects, and presented for a variety of parton distribution functions and choices of the renormalization/factorization scales and the strong coupling $\alpha_\mathrm{S}$

Observation of the rare decay of the η\eta meson to four muons

A search for the rare $\eta$$\to$$\mu^+\mu^-\mu^+\mu^-$ double-Dalitz decay is performed using a sample of proton-proton collisions, collected by the CMS experiment at the CERN LHC with high-rate muon triggers in 2017-2018 and corresponding to an integrated luminosity of 101 fb$^{-1}$. A signal having a statistical significance well in excess of 5 standard deviations is observed. Using the \emm decay as normalization, the branching fraction $\mathcal{B}($η$\to \mu^+\mu^-\mu^+\mu^-)$ = ( 5.0 $\pm$ 0.8 (stat) $\pm$ 0.7 (syst) $\pm$ 0.7 $\mathcal{B}_{2\mu}$ ) $\times$ 10$^{-9}$ is measured, where the last term is the uncertainty in the normalization channel branching fraction. This is the first measurement of this branching fraction and is found to be in agreement with theoretical predictions

Search for new physics in multijet events with at least one photon and large missing transverse momentum in proton-proton collisions at 13 TeV

A search for new physics in final states consisting of at least one photon, multiple jets, and large missing transverse momentum is presented, using proton-proton collision events at a center-of-mass energy of 13 TeV. The data correspond to an integrated luminosity of 137 fb$^{-1}$, recorded by the CMS experiment at the CERN LHC from 2016 to 2018. The events are divided into mutually exclusive bins characterized by the missing transverse momentum, the number of jets, the number of b-tagged jets, and jets consistent with the presence of hadronically decaying W, Z, or Higgs bosons. The observed data are found to be consistent with the prediction from standard model processes. The results are interpreted in the context of simplified models of pair production of supersymmetric particles via strong and electroweak interactions. Depending on the details of the signal models, gluinos and squarks of masses up to 2.35 and 1.43 TeV, respectively, and electroweakinos of masses up to 1.23 TeV are excluded at 95% confidence level

Luminosity determination using Z boson production at the CMS experiment

International audienceThe measurement of Z boson production is presented as a method to determine the integrated luminosity of CMS data sets. The analysis uses proton-proton collision data, recorded by the CMS experiment at the CERN LHC in 2017 at a center-of-mass energy of 13 TeV. Events with Z bosons decaying into a pair of muons are selected. The total number of Z bosons produced in a fiducial volume is determined, together with the identification efficiencies and correlations from the same dataset, in small intervals of 2 pb$^{-1}$ of integrated luminosity, thus facilitating the efficiency and rate measurement as a function of time and instantaneous luminosity. Using the ratio of the efficiency-corrected numbers of Z bosons, the precisely measured integrated luminosity of one data set is used to determine the luminosity of another. For the first time, a full quantitative uncertainty analysis of the use of Z bosons for the integrated luminosity measurement is performed. The uncertainty in the extrapolation between two data sets, recorded in 2017 at low and high instantaneous luminosity, is less than 0.5%. We show that the Z boson rate measurement constitutes a precise method, complementary to traditional methods, with the potential to improve the measurement of the integrated luminosity
