A tailored telephone and email based exercise intervention induced reductions in various measures of body composition in physically inactive adults: …
2018
Obesity prevalence has increased the past decades and has become a serious public health problem. The aim of this six-month assessor-blinded, parallel-group randomized controlled trial was to assess the effect of a tailored telephone and email-based exercise intervention on various measures of body composition in a sample of apparently healthy and physically inactive adults. A total of 111 volunteering adults (40–55 yr) in Southern Norway were randomly assigned to an intervention group (IG; n = 39) or a no-information control group (CG; n = 50), by random allocation numbering. The IG received feedback on their health-related physical fitness, information on guidelines and recommendations fo…
Los migrantes irregulares en el Mediterráneo: El caso italiano y sus contradicciones
2019
Benché il discorso pubblico continui a richiamare una emergenza immigrazione, lo studio muove dai dati della consistenza reale del fenomeno, fortemente decrescenti nell’ultimo anno e mezzo. Si avverte poi l’esigenza di rivisitare la rilevanza penalistica del migrante irregolare, per superare la sua considerazione come mero oggetto del relativo trafficking, e si propone di mantenere invece un aggancio alla sua condizione di persona, che svolge il ruolo di soggetto necessario del favoreggiamento all’immigrazione clandestina, ancorché diverso dall’autore del relativo fatto di reato. Ciò consente di inquadrare meglio anche i relativi diritti nella delicata fase dell’accoglienza, e di passare po…
(p,2)-equations resonant at any variational eigenvalue
2018
We consider nonlinear elliptic Dirichlet problems driven by the sum of a p-Laplacian and a Laplacian (a (p,2) -equation). The reaction term at ±∞ is resonant with respect to any variational eigenvalue of the p-Laplacian. We prove two multiplicity theorems for such equations.
Estudio comparado entre el impacto de la política migratoria estadounidense sobre la Frontera Norte de México y la política migratoria española sobre…
2020
A través de este trabajo, se pretende mostrar los resultados de la investigación sobre el terreno llevada a cabo en la ciudad fronteriza de Tijuana y algunos puntos clave de la frontera norte de México con Estados Unidos ubicados en la región de Baja California y California, para compararlos con los obtenidos en el estudio realizado en las ciudades autónomas de Ceuta y Melilla, además de otras localidades cercanas a la frontera sur de España con Marruecos. Su finalidad es establecer hasta qué punto el control de fronteras ha condicionado el patrón de desplazamientos de migrantes irregulares hacia estos países, y cuáles han sido sus consecuencias en las regiones fronterizas. Así, en primer l…
Abnormalities in alpha-dystroglycan expression in MDC1C and LGMD2I muscular dystrophies
2004
We recently identified mutations in the fukutin related protein (FKRP) gene in patients with congenital muscular dystrophy type 1C (MDC1C) and limb girdle muscular dystrophy type 2I (LGMD2I). The sarcolemma of these patients typically displays an immunocytochemical reduction of alpha-dystroglycan. In this report we extend these observations and report a clear correlation between the residual expression of alpha-dystroglycan and the phenotype. Three broad categories were identified. Patients at the severe end of the clinical spectrum (MDC1C) were compound heterozygote between a null allele and a missense mutation or carried two missense mutations and displayed a profound depletion of alpha-d…
Solutions with sign information for nonlinear Robin problems with no growth restriction on reaction
2019
We consider a parametric nonlinear Robin problem driven by a nonhomogeneous differential operator. The reaction is a Carathéodory function which is only locally defined (that is, the hypotheses concern only its behaviour near zero). The conditions on the reaction are minimal. Using variational tools together with truncation, perturbation and comparison techniques and critical groups, we show that for all small values of the parameter λ > 0, the problem has at least three nontrivial smooth solutions, two of constant sign and the third nodal.
Encoding specificity instead of online integration of real-world spatial regularities for objects in working memory
2022
Most objects show high degrees of spatial regularity (e.g. beach umbrellas appear above, not under, beach chairs). The spatial regularities of real-world objects benefit visual working memory (VWM), but the mechanisms behind this spatial regularity effect remain unclear. The "encoding specificity" hypothesis suggests that spatial regularity will enhance the visual encoding process but will not facilitate the integration of information online during VWM maintenance. The "perception-alike" hypothesis suggests that spatial regularity will function in both visual encoding and online integration during VWM maintenance. We investigated whether VWM integrates sequentially presented real-world obje…
Extremal Irregular Digraphs
2018
A digraph is called irregular if its distinct vertices have distinct degree pairs. An irregular digraph is called minimal (maximal) if the removal of any arc (addition of any new arc) results in a non-irregular digraph. It is easily seen that the minimum sizes among irregular n-vertex whether digraphs or oriented graphs are the same and are asymptotic to (√2/3) n3/2; maximum sizes, however, are asymptotic to n2 and n2/2, respectively. Let s stand for the sum of initial positive integers, s = 1, 3, 6, . . . . An oriented graph Hs and a digraph Fs, both large (in terms of the size), minimal irregular, and on any such s vertices, s ≥ 21, are constructed in [Large minimal irregular digraphs, Op…
Gradient and Lipschitz Estimates for Tug-of-War Type Games
2021
We define a random step size tug-of-war game and show that the gradient of a value function exists almost everywhere. We also prove that the gradients of value functions are uniformly bounded and converge weakly to the gradient of the corresponding $p$-harmonic function. Moreover, we establish an improved Lipschitz estimate when boundary values are close to a plane. Such estimates are known to play a key role in the higher regularity theory of partial differential equations. The proofs are based on cancellation and coupling methods as well as an improved version of the cylinder walk argument. peerReviewed
On the local and global regularity of tug-of-war games
2018
This thesis studies local and global regularity properties of a stochastic two-player zero-sum game called tug-of-war. In particular, we study value functions of the game locally as well as globally, that is, close to the boundaries of the game domains. Furthermore, we formulate a continuous time stochastic differential game and discuss, among other things, the equicontinuity of the families of value functions. The main motivation is to understand the properties of the games on their own right. As applications, we obtain an existence and a regularity result for a nonlinear elliptic p-Laplace type partial differential equation and a characterization of the solution to a parabolic p-Laplace typ…
