Theoretical issues in the conservation of contemporary art

CeROArt : Conservation, Exposition, Restauration d'Objets d'Art
The passage of time is inexorable and will have an inevitable repercussion on current works of art. In the case of contemporary art, many of the values included in artworks are linked to the pristine appearance and the conscious and specific use of a ...

Ruin Analysis of a Discrete-Time Dependent Sparre Andersen Model with External Financial Activities and Randomized Dividends

Risks, 2016
We consider a discrete-time dependent Sparre Andersen risk model which incorporates multiple threshold levels characterizing an insurer’s minimal capital requirement, dividend paying situations, and external financial activities.

Tuning the Dielectric Properties of Individual Clay Nanosheets by Interlayer Composition: Toward Nano‐Electret Materials

Advanced Functional Materials, EarlyView.
The dielectric properties of clays are studied on the level of individual monolayers and functional double stacks. The material breakdown characteristics and charge storage performance are analyzed. For illustration, a defined charge pattern representing a cuneiform character is produced, written into a microscopic clay tile, referencing the origins of

Ruin Probability in Compound Poisson Process with Investment

Journal of Applied Mathematics, 2012
We consider that the surplus of an insurer follows compound Poisson process and the insurer would invest its surplus in risky assets, whose prices satisfy the Black-Scholes model. In the risk process, we decompose the ruin probability into the sum of two

Composites of Shellac and Silver Nanowires as Flexible, Biobased, and Corrosion‐Resistant Transparent Conductive Electrodes

Advanced Functional Materials, EarlyView.
Shellac, a centuries‐old natural resin, is reimagined as a green material for flexible electronics. When combined with silver nanowires, shellac films deliver transparency, conductivity, and stability against humidity. These results position shellac as a sustainable alternative to synthetic polymers for transparent conductors in next‐generation ...

Mechanical Properties of Architected Polymer Lattice Materials: A Comparative Study of Additive Manufacturing and CAD Using FEM and µ‐CT

Advanced Functional Materials, EarlyView.
This study examines how pore shape and manufacturing‐induced deviations affect the mechanical properties of 3D‐printed lattice materials with constant porosity. Combining µ‐CT analysis, FEM, and compression testing, the authors show that structural imperfections reduce stiffness and strength, while bulk material inhomogeneities probably enhance ...

Ruining Image and the Image as Ruin: William Kentridge’s Trionfi e Lamenti in Rome

Babel: Littératures Plurielles
The essay examines South African visual artist William Kentridge’s monumental erase graffiti frieze Trionfi e Lamenti in Rome (2016), focusing on the artwork’s palimpsestic reworking of a visual archive of Rome and Roman triumphal iconography.

Calculating multivariate ruin probabilities via Gaver–Stehfest inversion technique. [PDF]

Multivariate characteristics of risk processes are of high interest to academic actuaries. In such models, the probability of ruin is obtained not only by considering initial reserves u but also the severity of ruin y and the surplus before ruin x.

Spleen‐Targeting Biomimetic Hybrid Nanocarriers for Systemic Immune Reprogramming in Colitis: RBC Membrane Vesicle‐Fused Lipid Nanoparticles

Advanced Functional Materials, EarlyView.
A spleen‐targeting hybrid nanoplatform (RBCMV‐LNP‐RP) harnessing erythrophagocytosis mimics senescent red blood cell clearance to achieve spleen‐specific delivery of rapamycin. This biomimetic system enables selective accumulation in splenic macrophages, orchestrating systemic immune reprogramming and promoting mucosal healing in an inflammatory bowel ...

Spectres de l’avenir. Sur un patrimoine en disparition dans les représentations de ruines anciennes et modernes

Babel: Littératures Plurielles
This paper attempts to explore the question of heritage in contemporary photography of ruins and to identify possible convergences between this and the painting of ruins in the Age of Enlightenment.
