Ordinary and calibrated differential operators, connections and application to curvilinear webs Open
Abelian relations of a curvilinear web are the solutions of the partial differential equation defined by a certain differential operator that we prove to be always "ordinary" and "calibrated". Thus we begin by explaning why the space of so…

Ordinary and calibrated differential operators Application to curvilinear webs Open
We study the space of the solutions $s$ of any system of partial differential equations $ D(j^ks)=0 $ defined by a linear and homogeneous differential operator $ D:J^kE\to F $ of any order $k\geq 1$, which is ``ordinary" (i.e. which is gen…

Controlled Nanopore Sizes in Supraparticle Supports for Enhanced Propane Dehydrogenation with GaPt SCALMS Catalysts Open
The efficient immobilization of GaPt liquid metal alloy droplets onto tailored supports improves catalytic performance by preventing coalescence and subsequent loss of active surface area. Herein, we use tailored supraparticle (SP) support…

A substructural logic for quantum measurements Open
This paper presents a substructural logic of sequents with very restricted exchange and weakening rules. It is sound with respect to sequences of measurements of a quantic system. A sound and complete semantics is provided. The semantic st…

Etude des (n+1)-tissus de courbes en dimension n Open
For $(n+1)$-webs by curves in an ambiant $n$-dimensional manifold, we first define a generalization of the well known Blaschke curvature of the dimension two, which vanishes iff the web has the maximum possible rank which is one. But, cont…

Technical Development and Economic Evaluation of the Integration of Thermal Energy Storage in Steam Power Plants Open
Grid-compliant integration of renewable energies will in future require considerable increases in flexibility in the operation of conventional power plants. The integration of thermal energy storage systems (TES) into the power plant proce…

Le rang des tissus de Nakai Open
According to Alain Hénaut, a planar 4-web is called Nakai's web if the cross-ratio of the tangents to the four foliations at each point is constant and if it has no hexagonal 3-subweb. We prove that Nakai's webs have rank 0 or 1. We give e…

Non-associative and projective linear logics Open
A non-commutative, non-associative weakening of Girard's linear logic is developed for multiplicative and additive connectives. Additional assumptions capture the logic of quantic measurements.

Representing choice functions by a total hyper-order Open
Choice functions over a set $X$ that satisfy the Outcast, a.k.a. Aizerman, property are exactly those that attach to any set its maximal subset relative to some total order of ${2}^{X}$.

Local optima, local equilibria and bounded complementarity in discrete exchange economies Open
In a discrete exchange economy an allocation is a local optimum if no transfer of a single item can improve the social welfare. In an economy in which all agents' valuations are $a$-submodular, i.e., exhibit complementarity bounded by $a$,…
