Lattice-Based Blind Signatures: Short, Efficient, and Round-Optimal
We propose a 2-round blind signature protocol based on the random oracle heuristic and the hardness of standard lattice problems (Ring/Module-SIS/LWE and NTRU) with a signature size of 22 KB. The protocol is round-optimal and has a transcript size that can ...
New York2023Liquid metal infiltration of silicon based alloys into porous carbonaceous materials. Part I: Modelling of channel filling and reaction phase formation
Ludger Weber, Alberto Ortona, Manoj Kondibhau Naikade
A relation for an adequate pore fraction needed to obtain residual Si and C free composites via reactive Si-X alloy infiltration is presented. The volume ratio of SiC and carbonaceous phase, the composition of the infiltrating liquid and the apparent densi ...
ELSEVIER SCI LTD2022The cohomology of semi-simple Lie groups, viewed from infinity
We prove that the real cohomology of semi-simple Lie groups admits boundary values, which are measurable cocycles on the Furstenberg boundary. This generalises known invariants such as the Maslov index on Shilov boundaries, the Euler class on projective sp ...
2022On rationally connected varieties over C1 fields of characteristic 0
We use birational geometry to show that the existence of rational points on proper rationally connected varieties over fields of characteristic 0 is a consequence of the existence of rational points on terminal Fano varieties. We discuss several consequenc ...
MATHEMATICAL SCIENCE PUBL2022On the projectivity of some moduli spaces of varieties
Quentin Arthur Frantisek Posva
This thesis is constituted of one article and three preprints that I wrote during my PhD thesis. Their common theme is the moduli theory of algebraic varieties. In the first article I study the Chow--Mumford line bundle for families of uniformly K-stable F ...
EPFL2022Positivity Of The Cm Line Bundle For K-Stable Log Fanos
We prove the bigness of the Chow-Mumford line bundle associated to a Q-Gorenstein family of log Fano varieties of maximal variation with uniformly K-stable general geometric fibers. This result generalizes a theorem of Codogni and Patakfalvi to the logarit ...
2022Algebra and geometry of link homology Lecture notes from the IHES 2021 Summer School
These notes cover the lectures of the first named author at 2021 IHES Summer School on "Enumerative Geometry, Physics and Representation Theory" with additional details and references. They cover the definition of Khovanov-Rozansky triply graded homology, ...
WILEY2022Latent Mechanisms of Polarization Switching from In Situ Electron Microscopy Observations
Vasiliki Tileli, Reinis Ignatans
In situ scanning transmission electron microscopy enables observation of the domain dynamics in ferroelectric materials as a function of externally applied bias and temperature. The resultant data sets contain a wealth of information on polarization switch ...
WILEY-V C H VERLAG GMBH2022Anchorage of shear reinforcement in beams and slabs
Aurelio Muttoni, Qianhui Yu, Miguel Fernández Ruiz, Frédéric Monney
Anchorage of shear reinforcement, such as links or stirrups, can be performed by providing hooks, bends or heads at their ends, by welding transverse reinforcement or by closing open stirrups with pins. Hooks and bends, also used to enhance the anchorage o ...
ELSEVIER SCI LTD2022Integrated Model for Comprehensive Digital Education Platforms
Denis Gillet, Maria Jesus Rodriguez Triana, Isabelle Barbara Marie-Hélène Cardia, Juan Carlos Farah, Kim Lan Phan Hoang
The trend towards generalized blended and active learning approaches in engineering education is redefining the requirements and the deployment schemes for digital education platforms. This paper presents a quadriptych techno- pedagogical model highlightin ...
