Asymptotic mean value formulas for parabolic nonlinear equations

2021

In this paper we characterize viscosity solutions to nonlinear parabolic equations (including parabolic Monge–Ampère equations) by asymptotic mean value formulas. Our asymptotic mean value formulas can be interpreted from a probabilistic point of view in terms of dynamic programming principles for certain two-player, zero-sum games. peerReviewed

Suite of Statistical Models Forecasting Latvian GDP

2014

Abstract We develop a suite of statistical models to forecast Latvian GDP. We employ various univariate and multivariate econometric techniques to obtain short-term GDP projections and to assess the performance of the models. We also comprise the information contained in components of GDP and obtain short-term GDP projections from disaggregated perspective. We run out-of-sample forecasting procedures to evaluate GDP projections and to assess forecasting accuracy of all individual statistical models. We conclude that factor and bridge models are among the best individually performing models in the suite. Forecasting accuracy obtained using disaggregated models of factor and bridge models is …

Common Stocks. Urban peripheries, social innovation and urban regeneration

2020

The peripheries have been considered over the years as a crucial policy challenge that has oriented policies and strategies at different levels of government. On the other hand, measures that stimulate local contexts to develop specific policies have assumed an extremely episodic and unpredictable character in which the public debate on urban regeneration has remained largely dominated by that of extraordinary and emergency intervention on the peripheries. The paper analyses the case study of transformation of the Cantieri Culturali alla Zisa in Palermo with the new Cre.Zi Plus platform transforming a neglected and abandoned building in a peripheral area by delivering services to the commun…

Dynamiques de développement et inégalités régionales en Chine

2009

Le rapide développement économique de la Chine a généré des inégalités socio-spatiales croissantes, qui se marquent par un décalage croissant entre provinces littorales et intérieures, et entre villes et campagnes. À partir de l’examen des données statistiques officielles chinoises, on peut clairement repérer une aggravation des déséquilibres internes de la Chine, qui sont des facteurs potentiels de déstabilisation sociale, en particulier dans le cas des paysans venus tenter leur chance dans les grandes aires urbaines littorales, ou chassés de leurs terres par l’expansion périmétropolitaine. Cela entraîne aujourd’hui une politique différenciée d’aménagement du territoire chinois visant à co…

Estimating the safety performance function for urban unsignalized four-legged one-way intersections in Palermo, Italy

2014

Abstract Starting from consideration that urban intersections are sites with promise for safety and operational improvements, the paper describes the steps taken to develop a crash predictive model for estimating the safety performance of urban unsignalized intersections located in Palermo, Italy. The focus is on unsignalized four-legged one-way intersections widespread in Italian downtowns. The sample considered in the study consist of 92 intersections in Palermo, Italy. For the study were collected crashes occurred in the sites during the years 2006-2012, geometric design and functional characteristics and traffic flow. Results showed that data were overdispersed and NB1 distributed. In o…

Molluscan antimicrobial peptides, a review from activity-based evidences to computer-assisted sequences

2011

Antimicrobial peptides (AMPs) represent the most universal immune effectors. Molluscs constitute the second largest animal phylum, after Arthropods, in term of number of species. Only a negligible number has been investigated regarding AMPs. The choice of the species to be studied relied on their economical importance and availability. First studies on molluscan AMPs dated from 1996 and were based on biological activities of biochemical-purified fractions. Such approach released all the original structures we know, with biological activity sometimes different from one isoform to another. Then, molecular biology techniques were applied to molluscan AMPs starting in 1999. Complete screening o…

Rifampicin is not an inhibitor of tyrosinase

2022

Rifampicin has been previously described as an inhibitor of tyrosinase (Chai et al., Int. J. Biol. Macromol. 102 (2017) 425–430). However, rifampicin contains a p-diphenol group and compounds with such a moiety have been shown before to reduce tyrosinase-generated o-quinones. Rifampicin also shows strong absorption in a region completely overlapping with the visible absorption band of dopachrome, the oxidation product of L-tyrosine and L-dopa, whose concentration is measured spectrophotometrically in the standard enzymatic assay to monitor the activity of tyrosinase. We have demonstrated that rifampicin is also rapidly oxidized by o-quinones generated from catechols by tyrosinase or by trea…

Genetic profile and immunohistochemical study of clear cell renal carcinoma: Pathological-anatomical correlation and prognosis.

2021

Abstract Introduction Renal cell carcinoma (RCC) accounts for 2–3% of all tumors being the most frequent solid lesion in the kidney. Objective To determine what genetic alterations and immunohistochemical (IHC) of clear cell renal carcinoma (ccRCC) are associated with prognosis and tumor aggressiveness. Patients and Methods Experimental analytical study with 57 patients who underwent radical and partial nephrectomy between 2005 and 2011, all with diagnosis of ccRCC and minimum post-operative follow-up of 36 months. The pathological study included IHC determination of biomarkers associated (CAIX, CAM 5.2, CD10, c-erbB-2, EGFR, HIF-1a, Ki67, MDM2, PAX-2 y 8, p53, survivin and VEGFR 1 and 2). …

Net currents obtained from zero-average potentials in single amphoteric nanopores

2013

We have studied experimentally and theoretically the rectifying properties of a single asymmetric nanopore functionalized with amphoteric lysine groups and characterized the net current obtained with zero-average time dependent potentials. The pH-controlled rectification phenomena may be relevant to bio-electrochemistry, pH sensing and regulation, and energy conversion. (C) 2013 Elsevier B.V. All rights reserved.
