Asymptotic Mean-Value Formulas for Solutions of General Second-Order Elliptic Equations
2022
Abstract We obtain asymptotic mean-value formulas for solutions of second-order elliptic equations. Our approach is very flexible and allows us to consider several families of operators obtained as an infimum, a supremum, or a combination of both infimum and supremum, of linear operators. The families of equations that we consider include well-known operators such as Pucci, Issacs, and k-Hessian operators.
Mezenhimālo stromas šūnu osteoģenēzes raksturojums uz amorfā kalcija fosfāta biomateriāla
2021
Mezenhimālās stromas šūnas ir plaši pētīts šūnu veids to potenciālo ārstniecisko efektu dēļ, no kuriem populārākie ir imūnmodulācija un audu reģenerācija. Bakalaura darbs bija fokusēts uz mezenhimālo stromas šūnu pielietojumu kaulaudu reģenerācijā un to biosaderību ar amorfo kalcija fosfātu, kas organismā atrodams kaula veidošanās sākumstadijā. Darba mērķis bija raksturot uz amorfā kalcija fosfāta biomateriāla audzētu mezenhimālo stromas šūnu osteoģenēzes potenciālu. Osteoģenēzes raksturošanai izmantoja osteokalcīna imūnfluorescento iezīmēšanu, savukārt, biosaderību analizēja ar kolorimetrisko CKK-8 analīzi. Rezultāti uzrādīja, ka mezenhimālas stromas šūnas ir spējīgas augt uz biomateriāla,…
Aspetti radiologici nell'osteonecrosi dei mascellari da bifosfonati e proposta di una classificazione radiologica in funzione dell'evoluzione clinica.

CAPITOLO I. OSTEONECROSI DELLE OSSA MASCELLARI (ONJ) FARMACO-RELATA
2020
Si definisce osteonecrosi delle ossa mascellari associata a bisfo- sfonati e/o altri farmaci una “reazione avversa farmaco-correlata, caratterizzata dalla progressiva distruzione e necrosi dell’osso mandibolare e/o mascellare di soggetti esposti al trattamento con farmaci per cui sia accertato un aumentato rischio di malat- tia, in assenza di un pregresso trattamento radiante”. In Tabella. 1.1 sono riportati i relativi criteri di inclusione, di esclusione e di dubbio.
LA GESTIONE ODONTOIATRICA DEL PAZIENTE CHE ASSUMERÀ O ASSUME FARMACI ONJ-RELATI
2020
L’osteonecrosi delle ossa mascellari (ONJ) farmaco-relata è stata de- finita nel capitolo I come “una reazione avversa farmaco-correlata, caratterizzata dalla progressiva distruzione e necrosi dell’osso man- dibolare e/o mascellare di soggetti esposti al trattamento con farmaci per cui sia accertato un aumentato rischio di malattia, in assenza di un pregresso trattamento radiante”1. Tale definizione sottolinea la consapevolezza di uno stato di allerta e di vigilanza sui fattori di ri- schio associati alla patologia, con la possibile progressiva inclusione di nuove popolazioni di soggetti potenzialmente a rischio, e in linea con la continua evoluzione delle conoscenze scientifiche in materia…
TRATTAMENTO DELLA OSTEONECROSI DELLE OSSA MASCELLARI FARMACO-RELATA (ONJ)
2020
Il trattamento di ONJ è, dalla sua comparsa in letteratura, argomen- to molto dibattuto, prima, come osteonecrosi delle ossa mascellari (BRONJ) associata a bisfosfonati (BP), recentemente un’ulteriore complessità si è aggiunta con l’identificazione di numerose molecole di nuova generazione, diverse dai BP, in grado di favorire lo sviluppo di ONJ (definite nel presente testo “non-BRONJ”); queste molecole, nei pazienti oncologici per lesioni scheletriche, sono prescritte più o meno in associazione o in sequenza con i BP stessi (e.g. denosu- mab, inibitori delle tirosin-kinasi, anticorpi monoclonali anti-VEGF, inibitori di mTOR)1–3.

Merging Features from Green's Functions and Time Dependent Density Functional Theory: A Route to the Description of Correlated Materials out of Equil…
2016
We propose a description of nonequilibrium systems via a simple protocol that combines exchange-correlation potentials from density functional theory with self-energies of many-body perturbation theory. The approach, aimed to avoid double counting of interactions, is tested against exact results in Hubbard-type systems, with respect to interaction strength, perturbation speed and inhomogeneity, and system dimensionality and size. In many regimes, we find significant improvement over adiabatic time dependent density functional theory or second Born nonequilibrium Green's function approximations. We briefly discuss the reasons for the residual discrepancies, and directions for future work.
The strong coupling constant: State of the art and the decade ahead
2022
This document provides a comprehensive summary of the state-of-the-art, challenges, and prospects in the experimental and theoretical study of the strong coupling $\alpha_s$. The current status of the seven methods presently used to determine $\alpha_s$ based on: (i) lattice QCD, (ii) hadronic $\tau$ decays, (iii) deep-inelastic scattering and parton distribution functions fits, (iv) electroweak boson decays, hadronic final-states in (v) e+e-, (vi) e-p, and (vii) p-p collisions, and (viii) quarkonia decays and masses, are reviewed. Novel $\alpha_s$ determinations are discussed, as well as the averaging method used to obtain the PDG world-average value at the reference Z boson mass scale, $\…
Investigations of Anisotropic Flow Using Multiparticle Azimuthal Correlations in pp, p-Pb, Xe-Xe, and Pb-Pb Collisions at the LHC
2019
Measurements of anisotropic flow coefficients ($v_n$) and their cross-correlations using two- and multi-particle cumulant methods are reported in collisions of pp at $\sqrt{s} = 13$ TeV, p-Pb at $\sqrt{s_{_{\rm NN}}} = 5.02$ TeV, Xe-Xe at $\sqrt{s_{_{\rm NN}}} = 5.44$ TeV, and Pb-Pb at $\sqrt{s_{_{\rm NN}}} = 5.02$ TeV recorded with the ALICE detector. The multiplicity dependence of $v_n$ is studied in a very wide range from 20 to 3000 particles produced in the mid-rapidity region $|��|<0.8$ for the transverse momentum range $0.2 < p_{\rm T} < 3.0$ GeV/$c$. An ordering of the coefficients $v_2 > v_3 > v_4$ is found in pp and p-Pb collisions, similar to that seen in large coll…
