Quantum Algorithm for Distribution-Free Junta Testing
2019
Inspired by a recent classical distribution-free junta tester by Chen, Liu, Serverdio, Sheng, and Xie (STOC’18), we construct a quantum tester for the same problem with complexity \(O(k/\varepsilon )\), which constitutes a quadratic improvement.
Complement proteins regulating macrophage polarisation on biomaterials
2019
[EN] One of the events occurring when a biomaterial is implanted in an host is the protein deposition onto its surface, which might regulate cell responses. When a biomaterial displays a compromised biocompatibility, distinct complement pathways can be activated to produce a foreign body reaction. In this article, we have designed different types of biomaterial surfaces to study the inflammation process. Here, we used different concentrations of (3-glycidoxypropyl)-trimethoxysilane (GPTMS), an organically-modified alkoxysilane as a precursor for the synthesis of various types of sol-gel materials functionalizing coatings for titanium implants to regulate biological responses. Our results sh…
Intralipotherapy, the State of the Art.
2016
Background: Reconstruction intralipotherapy is a term commonly used in the field of aesthetic medicine, above all in Europe, which defines a specific injection technique developed for the treatment of localized fat with substances that provoke the lysis of adipocytes by means of an injection directly into the adipose tissue with a long needle. The aim of this study is to define the technique in detail and everything that is associated with it, on the basis of years of multicenter experience by doctors who perform it. Materials and Methods: From January 2010 to December 2014, 3,080 European physicians were trained in intralipotherapy technique, and approximately 152,500 patients were treated…
Unravelling the GLY-PRO-GLU tripeptide induced reconstruction of the Au(110) surface at the molecular scale
2018
International audience; The adsorption of GLY-PRO-GLU tripeptide on Au(110) is investigated within the frame of all atom classical mechanics simulations and Density Functional Theory, focusing on the surface reconstruction. It is shown that the tripeptide adsorption reorganizes and restructures the Au(110) surface. A mechanism for the surface restructuration is proposed for both the neutral and zwitterionic form of the peptide at room temperature in Ultra High Vacuum. Diverse residues may be involved in the Au atoms displacement, and in particular glutamic acid, triggering a double proton transfer and the formation of a zwitter ionic state, is found to be responsible for the triggering of t…
Los edificios de la telefónica en Valencia (1926-1928)
2003
El artículo es un estudio del proceso de construcción y de la historia de los dos edificios para oficinas y central telefónica construidos en Valencia por la Compañía Telefónica Nacional de España entre 1926 y 1928. Tanto la sede central, situada en la plaza más importante de la ciudad, como la subcentral del distrito marítimo, ubicada en la popular barriada de El Grao de Valencia, constituyen por su tipología constructiva y su peculiaridad estética dos casos singulares en el panorama arquitectónico valenciano.

La tipología aeroportuaria en el patrimonio industrial: el caso del aeropuerto valenciano
2002
El objeto del presente artículo es esclarecer los comienzos históricos de la aviación valenciana y de las primeras instalaciones aeroportuarias que en nuestra ciudad tuvieron lugar realizando un recorrido hasta nuestros días. Antes de la definitiva instalación del aeropuerto en la municipalidad de Manises, se barajaron otras posibilidades que pretendemos dar a conocer y estudiar. Desde el aeródromo provisional en la Malvarrosa, el ambicioso proyecto de Francisco Mora en la Dehesa del Saler hasta el actual aeropuerto es interesante analizar las diferentes tipologías aeroportuarias y su adecuación a las necesidades de la siempre creciente aviación, configurando un tipo de edificio que plantea…
El monumento a la III Internacional de Vladimir Tatlin. Antecedentes iconográficos
1990
EL MONUMENTO A LA III INTERNACIONAL, OBRA MAESTRA DEL CONSTRUCTIVISMO RUSO, NO ES MAS QUE UNA UTOPIA, UNA MONTAÑA SIMBOLICA CON UNA DOBLE ESPIRAL, PARECIDA A VARIAS OBRAS DE LA ANTIGÜEDAD EN LAS QUE ESTA INSPIRADA. ADEMAS, EL MOVIMIENTO SE RELACIONA CON LA IDEA DE TIEMPO, VINCULADO A LOS MOVIMIENTOS CELESTES, COMO EN LAS TEORIAS ALQUIMICAS (A.B.C./ L.A.G.)
A Constructive Arboricity Approximation Scheme
2020
The arboricity \(\varGamma \) of a graph is the minimum number of forests its edge set can be partitioned into. Previous approximation schemes were nonconstructive, i.e., they approximate the arboricity as a value without computing a corresponding forest partition. This is because they operate on pseudoforest partitions or the dual problem of finding dense subgraphs.

Die neurotische Depression - Eine Krankheit ohne Diagnose oder eine Diagnose ohne Glossar?/ Neurotic depression – a disease without a diagnosis or a …
2003
With the transition from ICD-9 to ICD-10 the diagnosis of neurotic depression was omitted. Freyberger showed that this diagnosis in the ICD-10 was replaced mainly by the diagnoses of dysthymia, recurrent depression and depressive episode (with this ranking of frequency). A renowned German psychiatrist criticized this change as replacing an unsubstantiated dichotomic with an unsubstantiated dimensional model. The same was the case with the change from DSM-II to DSM-III: Torgersen criticized here that the heterogeneous diagnosis of neurotic depression was basically replaced by the similarly heterogeneous diagnosis of major depression. The underlying rationale behind the omission of the tradit…
