Thus, both decryption algorithms correctly recover M (b) Suppose there is an adversary A with advantage at least in the real-or-random game. Then we can construct the following algorithm B which solves the BDDH problem: * On input (P,Q,R, S, γ), send (P,Q,R) to A, where Q is interpreted as QA and R is interpreted as QB. * When A send the challenge plaintext M , respond with (S,Mγ) as the challe...

In a general setting, the transfinite interpolation problem requires constructing a single function´Üµ that takes on the prescribed values and/or derivatives on some collection of point sets. The sets of points may contain isolated points, bounded or unbounded curves, as well as surfaces and regions of arbitrary topology. All such closed semi-analytic sets may be represented implicitly by real ...

with input u(t) ∈ Rm, state x(t) ∈ RN and output y(t) ∈ Rp. Without loss of generality, we can assume that the system is controllable and observable since otherwise we can always find a smaller dimensional model that is controllable and observable, and that has exactly the same transfer function. In addition to this, we will assume that the system is stable, i.e. the generalized eigenvalues of ...

d p l p p s ê e f s d m es auteurs ont courageusement mené une étude originale ans sa thématique et ses objectifs [1]. Ils ont souhaité onnaître les modalités de prise en charge des patients orteurs de sondes vésicales à demeure par leur médecin énéraliste (donc en situation non institutionnalisée) et prooser des recommandations d’aide à la pratique permettant ’améliorer la qualité des soins et...

where α = max(|D(ui)|, |D(uj)|)+ ; is a small positive number. For notational simplicity, we denoteD(xi) = D(ui)xi, V (xi, xj) = V (ui, uj)xixj , V̂ (xi, xj) = V̂ (ui, uj)xixj , andR(xi, xj) = R(ui, uj)xixj . Lemma 1. If X∗ is the global optimum of E(X),R(xi, xj) < To,∀ xi ∼ xj , xi, xj ∈ X∗. Proof. If there exists a pair xi ∼ xj , xi, xj ∈ X∗ such thatR(xi, xj) ≥ To, then E(X∗) > 0 = E(0) (5) wh...

A quantization scheme for the phenomenological Maxwell theory of the full electromagnetic field in an inhomogeneous three-dimensional, dispersive and absorbing dielectric medium is developed. The classical Maxwell equations with spatially varying and Kramers–Kronig consistent permittivity are regarded as operator-valued field equations, introducing additional currentand charge-density operator ...

We use F. Ferrari’s methods relating matrix models to Calabi-Yau spaces in order to explain much of Intriligator and Wecht’s ADE classification of N = 1 superconformal theories which arise as RG fixed points of N = 1 SQCD theories with adjoints. We find that ADE superpotentials in the Intriligator–Wecht classification exactly match matrix model superpotentials obtained from Calabi-Yaus with cor...
