An evolutionary Haar-Rado type theorem

2021

AbstractIn this paper, we study variational solutions to parabolic equations of the type $$\partial _t u - \mathrm {div}_x (D_\xi f(Du)) + D_ug(x,u) = 0$$ ∂ t u - div x ( D ξ f ( D u ) ) + D u g ( x , u ) = 0 , where u attains time-independent boundary values $$u_0$$ u 0 on the parabolic boundary and f, g fulfill convexity assumptions. We establish a Haar-Rado type theorem: If the boundary values $$u_0$$ u 0 admit a modulus of continuity $$\omega $$ ω and the estimate $$|u(x,t)-u_0(\gamma )| \le \omega (|x-\gamma |)$$ | u ( x , t ) - u 0 ( γ ) | ≤ ω ( | x - γ | ) holds, then u admits the same modulus of continuity in the spatial variable.

Asymptotic Lipschitz regularity for tug-of-war games with varying probabilities

2018

We prove an asymptotic Lipschitz estimate for value functions of tug-of-war games with varying probabilities defined in $\Omega\subset \mathbb R^n$. The method of the proof is based on a game-theoretic idea to estimate the value of a related game defined in $\Omega\times \Omega$ via couplings.

On the regularity of very weak solutions for linear elliptic equations in divergence form

2020

AbstractIn this paper we consider a linear elliptic equation in divergence form $$\begin{aligned} \sum _{i,j}D_j(a_{ij}(x)D_i u )=0 \quad \hbox {in } \Omega . \end{aligned}$$ ∑ i , j D j ( a ij ( x ) D i u ) = 0 in Ω . Assuming the coefficients $$a_{ij}$$ a ij in $$W^{1,n}(\Omega )$$ W 1 , n ( Ω ) with a modulus of continuity satisfying a certain Dini-type continuity condition, we prove that any very weak solution $$u\in L^{n'}_\mathrm{loc}(\Omega )$$ u ∈ L loc n ′ ( Ω ) of (0.1) is actually a weak solution in $$W^{1,2}_\mathrm{loc}(\Omega )$$ W loc 1 , 2 ( Ω ) .

Partial Data Problems and Unique Continuation in Scalar and Vector Field Tomography

2022

AbstractWe prove that if P(D) is some constant coefficient partial differential operator and f is a scalar field such that P(D)f vanishes in a given open set, then the integrals of f over all lines intersecting that open set determine the scalar field uniquely everywhere. This is done by proving a unique continuation property of fractional Laplacians which implies uniqueness for the partial data problem. We also apply our results to partial data problems of vector fields.

Exergaming usage : hedonic and utilitarian aspects

2017

There is a growing demand for information systems (IS) that could advance desirable health behaviours among people. While digital gaming has generally been perceived to increase individuals’ sedentary time, gaming can also act as a medium to promote health, for example, by increasing individuals’ levels of physical activity. Exergaming, a form of digital gaming that combines games with physical activity, has been mentioned as potential means of influencing physical activity levels. Previous research on exergaming has been dominated by a very device-centric perspective, focusing more on its technological and physical aspects, than a more user-centric perspective that focuses on the users and…

Influencia de la instrumentación con lima única en la calidad de la obturación del sistema de conductos radiculares mediante la técnica de condensaci…

2015

1.- Introducción: el principal objetivo en la terapia endodóncica es simplificar los procedimientos con completa seguridad y eficacia. Como alternativa a los sistemas rotatorios multilima, se crearon los sistemas de lima única de rotación alternante, con el fin de reducir la fatiga cíclica para disminuir el riesgo de fractura de los instrumentos, la deformidad del conducto radicular, rapidez y simplicidad en la conformación. Posteriormente, aparecieron sistemas de lima única de rotación continua que también aumentaron la rapidez y la simplicidad. Con la finalidad de analizar la capacidad de conformar los conductos radiculares de estos sistemas endodóncicos se realizó este estudio. 2.- Objet…

Environmental Enrichment During Adolescence Mitigates Cognitive Deficits and Alcohol Vulnerability due to Continuous and Intermittent Perinatal Alcoh…

2020

Perinatal alcohol exposure affects ontogenic neurodevelopment, causing physical and functional long-term abnormalities with limited treatment options. This study investigated long-term consequences of continuous and intermittent maternal alcohol drinking on behavioral readouts of cognitive function and alcohol vulnerability in the offspring. The effects of environmental enrichment (EE) during adolescence were also evaluated. Female rats underwent continuous alcohol drinking (CAD)—or intermittent alcohol drinking paradigm (IAD), along pregestation, gestation, and lactation periods—equivalent to the whole gestational period in humans. Male offspring were reared in standard conditions or EE un…
