Inverse Tone Mapping Based upon Retina Response
2014
International audience; The development of high dynamic range (HDR) display arouses the research of inverse tone mapping methods, which expand dynamic range of the low dynamic range (LDR) image to match that of HDR monitor. This paper proposed a novel physiological approach, which could avoid artifacts occurred in most existing algorithms. Inspired by the property of the human visual system (HVS), this dynamic range expansion scheme performs with a low computational complexity and a limited number of parameters and obtains high-quality HDR results. Comparisons with three recent algorithms in the literature also show that the proposed method reveals more important image details and produces …
Etude dynamique et structurale de biomolécules par microscopie à force atomique HS-AFM : application à une petite protéine de choc thermique sHsp
2012
The atomic force microscopy (AFM) gives access to the topography of organic and inorganic samplesat the atomic scale. The latest innovations offer the possiblity to understand the sample nano-mechanicalproperties (elasticity, adhesion...). Its feature set allows overcoming the demands of nanotechnology,both in the fields of physics, chemistry and biology.However, understanding biological processes require faster acquisitions for the atomic forcemicroscopy, less than a second per frame. As conventional equipment does not offer the possibility toovercome the constraint of time for dynamical studies, a prototype of high-speed atomic forcemicroscope (HS-AFM) was developed in partnership with Pr…
Teoria malarstwa abstrakcyjnego a Platońska koncepcja sztuki
2016
Tezą artykułu jest twierdzenie, że w założeniach teoretycznych malarstwa abstrakcyjnego odnajdujemy Platońską koncepcję sztuki. Jest to interesująca zbieżność, tym bardziej że jest ona niezależna, nie wynika z inspiracji abstrakcjonistów filozofią Platona, czy odwoływania się do jego koncepcji sztuki. Także Platon nie zakładał rozwoju takiego kierunku w sztuce, a mimo to u podstaw teoretycznych malarstwa abstrakcyjnego odnajdujemy te same prawdziwościowe, poznawcze założenia co w Platońskiej koncepcji sztuki. Określają one zarówno jej istotę, jak i funkcję oraz wartość. Stanowią także wyraz negatywnego stosunku Platona do malarstwa naśladowczego.
Aavesärkyä kertomuksen rakenteissa : kerronnalliset ja sukupuoliset rajanylitykset Taneli Viljasen teoksessa "Kaikki tilat ovat täynnä aaveita"
2020
Taneli Viljasen romaani kutsuu tarkastelemaan itseään tekstitilana, jossa äänet kaikuvat. Teos hyödyntää tekstuaalisia strategioita, jotka tekevät ääniä yksilöivän paikantamisen ja kokemuksellisuuteen perustuvat tulkinnat lähes mahdottomiksi. Kertomuksen kehyksiin sekä aikaan, tilaan ja kausaalisuuteen liittyvät antimimeettiset ratkaisut toimivat siinä myös queeristi, rikkoen oletuksia sukupuolen luonnollisuudesta, pysyvyydestä ja helposta tulkittavuudesta. peerReviewed
Emerging Therapies For Raising Hdl-C And Augmenting Hdl Particle Functionality
2013
High-density lipoprotein particles are highly complex polymolecular aggregates capable of performing a remarkable range of atheroprotective functions. Considerable research is being performed throughout the world to develop novel pharmacologic approaches to: (1) promote apoprotein A-I and HDL particle biosynthesis; (2) augment capacity for reverse cholesterol transport so as to reduce risk for the development and progression of atherosclerotic disease; and (3) modulate the functionality of HDL particles in order to increase their capacity to antagonize oxidation, inflammation, thrombosis, endothelial dysfunction, insulin resistance, and other processes that participate in arterial wall inju…

Study of [2-(2’-pyridyl)imidazole] complexes to confirm two main characteristic thermoanalytical behaviors of transition metal complexes based on imi…
2016
Abstract Imidazole derivative ligands are recognized as useful models for biomimetic complexes. Among the inorganic–organic hybrid complexes, those with derivatives of imidazole heterocyclic N-donor ligands are interesting for their framework. In previous studies of complexes with imidazole derivative ligands, our group reported two main thermally induced decomposition behaviors supporting two different systematic decomposition trends. In this work, one of these characteristic decomposition mechanisms was again found. The final goal of these serial studies is the possibility to provide, by the experimental evidences, a prediction model of thermal stability and decomposition typical behavior…
Application of CEC procedures for the analysis of synthetic peptides: characterization of linear immunogenic peptides that mimic a HIV-1 gp120 epitope
2002
In this study, we describe the application of a new analytical procedure based on capillary electrochromatographic(CEC) techniques for the characterization of different basic and acidic peptides using isocratic eluent conditions containing acetonitrile and ammonium acetate buffers of different molarities between pH 3.8 and 5.2. In particular,10 immunogenic peptide analogs with isoelectric points ranging from 3.7 to 10.1 were investigated; nine of these peptides, 1-9, were truncated analogs of the parent peptide, 10, which is a peptidomimetic related to a HIV-1 gp120 epitope. Several of these peptides have the propensity to form alpha-helical secondary structures in solution. Electrochromato…
A Step into the Future: Applications of Nanoparticle Enzyme Mimics.
2018
We describe elementary concepts, up-to-date developments, and perspectives of the emerging field of nanoparticle enzyme mimics (so-called "nanozymes") at the interface of chemistry, biology, materials, and nanotechnology. The design and synthesis of functional enzyme mimics is a long-standing goal of biomimetic chemistry. Metal complexes, polymers and engineered biomolecules capturing the structure of natural enzymes or their active centers have been made to achieve high rates and enhanced selectivities. Still, the design of new "artificial enzymes" that are not related to proteins but with capacity of production and stability at industrial level, remains a goal. Inorganic nanoparticles bea…
