Gestione delle acque marine e Sanità Pubblica tra normative, criticità e prospettive.
2010
Il mare copre il nostro pianeta per circa il 71% della superficie terrestre e gioca un ruolo fondamentale nella vita dell’uomo. Le acque marine sono connesse con la Sanità Pubblica a vari livelli, infatti sia lo stato di salute e benessere individuale che di popolazione risulta influenzato dalle condizioni del mare e delle sue risorse in maniera positiva o negativa. Milioni di individui ogni anno in Italia, per attività balneare ricreativa, si concentrano per periodi relativamente ristretti in litorali più o meno estesi spesso ubicati in diretta continuità con le realtà urbane e metropolitane di fatto determinando un potenziale ambito di contatto tra le attività antropiche e lo smaltimento …
On Limits at Infinity of Weighted Sobolev Functions
2022
We study necessary and sufficient conditions for a Muckenhoupt weight $w \in L^1_{\mathrm{loc}}(\mathbb R^d)$ that yield almost sure existence of radial, and vertical, limits at infinity for Sobolev functions $u \in W^{1,p}_{\mathrm{loc}}(\mathbb R^d,w)$ with a $p$-integrable gradient $|\nabla u|\in L^p(\mathbb R^d,w)$. The question is shown to subtly depend on the sense in which the limit is taken. First, we fully characterize the existence of radial limits. Second, we give essentially sharp sufficient conditions for the existence of vertical limits. In the specific setting of product and radial weights, we give if and only if statements. These generalize and give new proofs for results of…
Two examples related to conical energies
2022
In a recent article we introduced and studied conical energies. We used them to prove three results: a characterization of rectifiable measures, a characterization of sets with big pieces of Lipschitz graphs, and a sufficient condition for boundedness of nice singular integral operators. In this note we give two examples related to sharpness of these results. One of them is due to Joyce and M\"{o}rters, the other is new and could be of independent interest as an example of a relatively ugly set containing big pieces of Lipschitz graphs.
Peak oxygen uptake cut-points to identify children at increased cardiometabolic risk - The PANIC Study.
2019
We aimed to develop cut -points for directly measured peak oxygen uptake (VO2peak ) to identify boys and girls at increased cardiometabolic risk using different scaling methods to control for body size and composition. Altogether 352 children (186 boys, 166 girls) aged 9 – 11 years were included in the analyses. We measured VO2peak directly during a maximal cycle ergometer exercise test and lean body mass (LM) by bioelectrical impedance. We computed a sex - and age -specific cardiometabolic risk score (CRS) by summing important cardiometabolic risk factors and defined increased cardiometabolic risk as >1 standard deviation above the mean of CRS. Receiver operating characteristics curves wer…
Dubái: estrategias para una posible transición urbana
2020
The article presents the work "Dubai Pop-Up. Architecture in a transient city", the result of an international design workshop (coordinated by T. Aglieri Rinella and R. Garcia Rubio) which brought the Dubai question to the center, bringing together a large number of teachers and students to think how to introduce new ways of thinking about the city. Thanks to the diversified and sometimes surprising hypotheses that the projects developed suggest, it is clear how open the degree of alternatives to that development model only oriented on the “monoculture of profit” that has guided urban choices in this city up to now can still be.
Long-term monitoring of the TeV emission from Mrk 421 with the ARGO-YBJ experiment
2011
ARGO-YBJ is an air shower detector array with a fully covered layer of resistive plate chambers. It is operated with a high duty cycle and a large field of view. It continuously monitors the northern sky at energies above 0.3 TeV. In this paper, we report a long-term monitoring of Mrk 421 over the period from 2007 November to 2010 February. This source was observed by the satellite-borne experiments Rossi X-ray Timing Explorer and Swift in the X-ray band. Mrk 421 was especially active in the first half of 2008. Many flares are observed in both X-ray and gamma-ray bands simultaneously. The gamma-ray flux observed by ARGO-YBJ has a clear correlation with the X-ray flux. No lag between the X-r…
A Critical Review of Alien Limb-Related Phenomena and Implications for Functional Magnetic Resonance Imaging Studies
2021
Consensus criteria on corticobasal degeneration (CBD) include alien limb (AL) phenomena. However, the gist of the behavioral features of AL is still “a matter of debate.” CBD-related AL has so far included the description of involuntary movements, frontal release phenomena (frontal AL), or asomatognosia (posterior or “real” AL). In this context, the most frequent symptoms are language and praxis deficits and cortical sensory misperception. However, asomatognosia requires, by definition, intact perception and cognition. Thus, to make a proper diagnosis of AL in the context of CBD, cognitive and language dysfunctions must be carefully verified and objectively assessed. We reviewed the current…
Individual differences in behavioral consistency are related to sequential access to resources and body condition in a producer-scrounger game
2014
Investigating the evolution of consistent between-individual behavioral differences necessitates to explain the emergence of within-individual consistency. Relying on a recent mathematical model, we here test the prediction that the emergence of differences in within-individual consistency is related to the sequential access to resources in a frequency-dependent foraging game. To this end we used flocks of zebra finches (Taeniopygia guttata) engaged in a producer-scrounger foraging game. Tactic investment (i.e., the proportion of hops with the head down) significantly predicted successful tactic use (i.e., the proportion of seeds produced). In support of predictions, we found that individua…
