Widening use of dexamethasone implant for the treatment of macular edema
2017
Vincenza Bonfiglio, Michele Reibaldi, Matteo Fallico, Andrea Russo, Alessandra Pizzo, Stefano Fichera, Carlo Rapisarda, Iacopo Macchi, Teresio Avitabile, Antonio Longo Department of Ophthalmology, University of Catania, Catania, Italy Abstract: Sustained-release intravitreal 0.7 mg dexamethasone (DEX) implant is approved in Europe for the treatment of macular edema related to diabetic retinopathy, branch retinal vein occlusion, central retinal vein occlusion, and non-infectious uveitis. The implant is formulated in a biodegradable copolymer to release the active ingredient within the vitreous chamber for up to 6 months after an intravitreal injection, allowing a prolonged interval of effica…
Inverse Kinematics for a 7 DOF Robotic Arm Using the Redundancy Circle and ANFIS Models
2014
In this paper we have presented a method to solve the inverse kinematics problem of a redundant robotic arm with seven degrees of freedom and a human like workspace based on mathematical equations, ANFIS implementation and Simulink models. For better visualization of the kinematics simulation a CAD model that mimics the real robotic arm was created into SolidWorks® and then the CAD parts were converted into SimMechanics model.

The inverse kinematics solutions of a 7 DOF robotic arm using Fuzzy Logic
2012
This paper focuses on modeling resolving and simulations of the inverse kinematics of an anthropomorphic redundant robotic structure with seven degrees of freedom and a workspace similar to human arm. Also the kinematical model and the kinematics equations of the robotic arm are presented. A method of resolving the redundancy of seven degrees of freedom robotic arm is presented using Fuzzy Logic toolbox from MATLAB®.
Executive functions in kindergarten children at risk for developmental coordination disorder
2018
Executive functioning (EF) is a key cognitive process for development. Little is known about EF in Kindergarten children at risk for developmental coordination disorder (DCD), despite this age being one of the most critical and intensive period of motor and cognitive development. In our investigation we compared EF in kindergarten children at risk for DCD with Typically Developing (TD) children. Participants were 36 Italian children, 18 at risk for DCD (9 boys and 9 girls) who had a mean age of 4.6 years and 18 TD (9 boys and 9 girls) who had a mean age of 4.6. Executive functions were measured by tasks targeting cold executive functioning (working memory, fluency, inhibitory control) and t…
Migración residencial y urbanismo expansivo en el mediterráneo español
2015
Este artículo investiga la migración internacional de jubilados noreuropeos hacia España y su influencia en el desarrollo del urbanismo expansivo en nuestro país. Los temas clave que en este artículo se analizan son la expansión del urbanismo expansivo durante la burbuja inmobiliaria española, la cantidad y distribución de los jubilados noreuropeos residentes en España, y la relación entre la llegada de dichos migrantes residenciales y la difusión del urbanismo expansivo. Este artículo explica los motivos de esta migración residencial, que están principalmente relacionados con el clima y el estilo de vida mediterráneos. También describe los beneficios y los inconvenientes de dicha migración…
El uso de GPS para el análisis del comportamiento espacio-temporal de los turistas. Pre-test en el Valle de Boí
2015
Este artículo es un análisis exploratorio sobre el uso de los GPS para estudiar el comportamiento de los visitantes en un espacio abierto. El Valle de Boí es un escenario turístico que ofrece diversos recursos de primer orden, por lo que el estudio de los recorridos de los visitantes permite analizar la respuesta a estímulos muy diferentes. Los resultados demuestran que el recurso del GPS en espacios abiertos permite ampliar la información sobre el uso social del espacio turístico y abre las puertas a nuevas formas de análisis. This article is an exploratory analysis of the use of GPS for the study of visitors’ behaviour in an open space. The Boi Valley is an open space that offers importan…
Do you know what you are reading for? Exploring the effects of a task model enhancement on fifth graders' purposeful reading
2021
International audience; Background: Drawing on theories of purposeful reading, this study explored task conditions that support fifth graders' selective reading of documents in order to answer questions. More specifically, we investigated whether promoting students' elaboration of their task model increases task performance. Methods: Participants had to answer series of questions by searching documents for the relevant information. Half the participants received a task model prompt, and half received a control prompt. Participants' eye movements were recorded during text search, in order to investigate more precisely the effect of an enhanced task model. Results: Participants provided more …
On the Almost Everywhere Convergence of Multiple Fourier-Haar Series
2019
The paper deals with the question of convergence of multiple Fourier-Haar series with partial sums taken over homothetic copies of a given convex bounded set $$W\subset\mathbb{R}_+^n$$ containing the intersection of some neighborhood of the origin with $$\mathbb{R}_+^n$$ . It is proved that for this type sets W with symmetric structure it is guaranteed almost everywhere convergence of Fourier-Haar series of any function from the class L(ln+L)n−1.
Controlled polyhedral sweeping processes: existence, stability, and optimality conditions
2021
This paper is mainly devoted to the study of controlled sweeping processes with polyhedral moving sets in Hilbert spaces. Based on a detailed analysis of truncated Hausdorff distances between moving polyhedra, we derive new existence and uniqueness theorems for sweeping trajectories corresponding to various classes of control functions acting in moving sets. Then we establish quantitative stability results, which provide efficient estimates on the sweeping trajectory dependence on controls and initial values. Our final topic, accomplished in finite-dimensional state spaces, is deriving new necessary optimality and suboptimality conditions for sweeping control systems with endpoint constrain…
