Intravitreal triamcinolone, bevacizumab and pegaptanib for occult choroidal neovascularization.

PURPOSE: To evaluate best-corrected visual acuity (BCVA) and foveal thickness (FT) changes in occult subfoveal choroidal neovascularization (CNV) from age-related macular degeneration (AMD) after intravitreal bevacizumab (IVB, 1.25 mg/0.05 ml), pegaptanib (IVP, 0.3 mg/0.09 ml) and triamcinolone acetonide (IVTA, 4 mg/0.1 ml) injected on an as needed basis. METHODS:   Retrospective, interventional, comparative study. BCVA (Early Treatment Diabetic Retinopathy Study LogMAR) and FT by optical coherence tomography (OCT) were evaluated during 12 months from first treatment. Patients were retreated if signs of neovascular activity were still present on angiography or OCT. RESULTS: Forty-eight eyes received IVB, 43 eyes received IVP, 52 eyes received IVTA. BCVA and FT at baseline were 1.22 ± 0.49 LogMAR and 410.2 ± 41.83 μm in the IVB group, 1.25 ± 0.43 LogMAR and 452.3 ± 44.83 μm in the IVP group and 1.31 ± 0.4 LogMAR and 456.6 ± 48.27 μm in the IVTA group. BCVA and FT improved in the three groups during follow-up. A significantly greater improvement of BCVA was present at month-3, month-6 and at month-12 in the IVB and IVP groups (p = 0.01). Improvement of FT was greater in the IVTA group at month-3 (p = 0.02), while it was greater in the anti-Vascular Endothelial Growth Factor (VEGF) groups at month-6 and month-12 (p = 0.01). A postoperative increase of intraocular pressure was detected in 9/52 (17.3%) eyes treated with IVTA, and in two cases it was resistant to topical therapy. CONCLUSION:   Intravitreal injection of anti-VEGF drugs administered on an as needed basis for AMD-related occult CNVs provided functional and anatomic improvement during 12 months of follow-up

Study of low-energy nuclear recoils in liquid argon with the ReD experiment

Liquid Argon (LAr) Time Projection Chambers (TPC) operating in double-phase can detect the nuclear recoils (NR) possibly caused by the elastic scattering of WIMP dark matter particles via light signals from both scintillation and ionization processes. In the scenario of a low-mass WIMP (< 2 GeV/c2), the energy range for the NRs would be below 20 keV, thus making it crucial to characterize the ionization response in LAr TPCs as the lone available detection channel at such low energy. The Recoil Directionality (ReD) project, within the Global Argon Dark Matter Collaboration, aims to measure the ionization yield of a LAr TPC in the recoil energy range of 2-5 keV. The measurement was performed in winter 2023 at the INFN Sezione of Catania and the analysis is ongoing

How Cantillon and Hume Propose the Same Theory of First-Round Effects

Richard Cantillon and David Hume both propose the theory of monetary non-neutrality, whereby the money supply changes through the money balances of specific individuals. Such an uneven distribution of monetary change then spreads throughout the economy step by step and changes relative prices. While a number of authors note that Hume and Cantillon both present the same theory, they do so without seeking confirmation from the original texts. I fill this gap in the literature by identifying the main constituent parts of the theory in the contributions of both Cantillon and Hume

Directionality for nuclear recoils in a LAr TPC

In the direct searches for Weakly Interacting Massive Particles (WIMPs) as Dark Matter candidates, the sensitivity of the detector to the incom- ing particle direction could provide a smoking gun signature for an interesting event. The SCENE collaboration firstly suggested the possible directional de- pendence of a dual-phase argon Time Projection Chamber through the columnar recombination effect. The Recoil Directionality project (ReD) within the Global Argon Dark Matter Collaboration aims to characterize the light and charge re- sponse of a liquid Argon dual-phase TPC to neutron-induced nuclear recoils to probe for the hint by SCENE. In this work, the directional sensitivity of the de- tector in the energy range of interest for WIMPs (20-100 keV) is investigated with a data-driven analysis involving a Machine Learning algorithm

LA CONSERVAZIONE PREVENTIVA E PROGRAMMATA. VENTI ANNI DOPO IL CODICE DEI BENI CULTURALI Bressanone (BZ), 2 - 5 luglio 2024

The research aims to delineate the role and centrality of the Registrar within the network of a cultural institution, thus contributing to its professional and social recognition, and introducing a new approach to investigating cultural professionals. Despite their crucial role in Heritage management and preservation, the Registrar lacks adequate acknowledgment and appreciation. This study adopts an interdisciplinary approach, integrating qualitative and quantitative codification of data to clarify the Registrar’s role and responsibilities in Italy and to re-establish the connection between the labor market and the national educational system. Through collaboration with national and international academic and professional institutions, as well as the analysis of skills and educational paths, the goal is to provide a comprehensive overview of the Registrar’s position in Italian cultural institutions

Апріорні оцінки похибки наближення для гіллястих ланцюгових дробових розвинень гіпергеометричних функцій Горна $H_4$ та їх відношень

The paper considers the extension of analytic functions by a special family of functions — branched continued fractions. The truncation error bounds for branched continue fraction expansions of the Horn's hypergeometric functions $H_4$and their ratios with certain conditions on real parameters are established. In this case, a new domain of analytical continuation of these functions is also established using the PF method (based on the so-called property of fork for approximants of a branched continued fraction).У статті розглядається розвинення аналітичних функцій спеціальною сім'єю функцій — гіллястих ланцюгових дробів. Встановлено оцінки похибки наближення для гіллястих ланцюгових дробових розвинень гіпергеометричних функцій Горна$$$H_4$$$ та їх відношень за певних умов на дійсні параметри. У цьому випадку також встановлено нову область аналітичного продовження цих функцій за допомогою PF методу (на основі так званої властивості вилки для апроксимантів гіллястого ланцюгового дробу)
