Almost flat angles in surface superconductivity
Type-II superconductivity is known to persist close to the sample surface in presence of a strong magnetic field. As a consequence, the ground state energy in the Ginzburg–Landau theory is approximated by an effective one-dimensional model. As shown by Correggi and Giacomelli (2021 Calc. Var. Partial Differential Equations in press), the presence of corners on the surface affects the energy of the sample with a non-trivial contribution. In (Correggi and Giacomelli 2021 Calc. Var. Partial Differential Equations in press), the two-dimensional model problem providing the corner energy is implicitly identified and, although no explicit dependence of the energy on the corner opening angle is derived, a conjecture about its form is proposed. We study here such a conjecture and confirm it, at least to leading order, for corners with almost flat opening angle

On the Ginzburg–Landau energy of corners
It is a well known fact that the geometry of a superconducting sample influences the distribution of the surface superconductivity for strong applied magnetic fields. For instance, the presence of corners induces geometric terms described through effective models in sector-like regions. We study the connection between two effective models for the offset of superconductivity and for surface superconductivity introduced in Bonnaillie-Noël and Fournais (2007 Rev. Math. Phys. 19 607-37) and Correggi and Giacomelli (2021 Calc. Var. PDE 60 236), respectively. We prove that the transition between the two models is continuous with respect to the magnetic field strength, and, as a byproduct, we deduce the existence of a minimizer at the threshold for both effective problems. Furthermore, as a consequence, we disprove a conjecture stated in Correggi and Giacomelli (2021 Calc. Var. PDE 60 236) concerning the dependence of the corner energy on the angle close to the threshold

Implant survival after sinus elevation with Straumann(®) BoneCeramic in clinical practice: ad-interim results of a prospective study at a 15-month follow-up.
Abstract: Objectives
Elevation of the sinus floor with Straumann (R) BoneCeramic gave promising results in some recent clinical studies. However, no study has evaluated the long-term survival of implants after this surgical procedure. We are conducting a prospective, observational study to evaluate the long-term implant survival after this surgical procedure in clinical practice. We present here an ad-interim report of this study, including only patients with >= 12-month follow-up after implant placement.
Methods
This prospective cohort study will last until a follow-up of 5 years will be achieved in at least 50 patients. Inclusion criteria are: age >= 18 years; presence of a maxillary partial unilateral or bilateral edentulism involving the premolar/molar areas; elective rehabilitation with oral implants; and physical capability to tolerate conventional surgical and restorative procedures. Patients are treated according to the two-stage technique and the preparation is filled with Straumann (R) BoneCeramic. Implant survival is evaluated every 3 months for the first 2 years, and then every 6 months up to 5 years.
Results
Fifteen patients are considered in this ad-interim analysis. Mean follow-up was 14.9 +/- 3.1 (range: 6-18 months). In total, three implants failed, in one single patient, 6 months after insertion. The cumulative implant survival rate was 92.5% (95% confidence interval: 83.0-100%).
Conclusions
This ad-interim analysis suggests that the elevation of the sinus floor with Straumann (R) BoneCeramic may be an effective clinical option over > 1-year follow-up. A longer term follow-up will allow a deeper characterization of these preliminary findings

L'arte di 'fare memoria' due casi marchigiani: Anselmo Bucci e Mario Giacomelli
Il saggio prende in esame il rapporto del pittore Anselmo Bucci e del fotografo Mario Giacomelli con le rispettive realtà ambientali d'origine. L'obiettivo è di mettere in luce, pur nella differenza temporale (Bucci appartiene alla prima, Giacomelli alla seconda metà del secolo XX), il carattere 'marchigiano' delle rispettive opere come collegamento a una idea del 'vero' che si giova di fondamentali arricchimenti presi dalla cultura contemporanea più innovativa e cosmopolita
