Special Cases of the Parking Functions Conjecture and Upper-Triangular Matrices [PDF]
Discrete Mathematics & Theoretical Computer Science, 2011 We examine the $q=1$ and $t=0$ special cases of the parking functions conjecture. The parking functions conjecture states that the Hilbert series for the space of diagonal harmonics is equal to the bivariate generating function of $area$ and $dinv$ over ...

Quantum criticality in many-body parafermion chains
SciPost Physics Core, 2021 We construct local generalizations of 3-state Potts models with exotic critical points. We analytically show that these are described by non-diagonal modular invariant partition functions of products of $Z_3$ parafermion or $u(1)_6$ conformal field ...

On the main diagonal of sheffer functions
Discrete Mathematics, 1978 AbstractNecessary and sufficient conditions for a one variable function to be the main diagonal of a Sheffer function are given and estimates are obtained for the number of Sheffer functions.

Diagonally Non-Computable Functions and Bi-Immunity [PDF]
The Journal of Symbolic Logic, 2013 AbstractWe prove that every diagonally noncomputable function computes a set A which is bi-immune, meaning that neither A nor its complement has an infinite computably enumerable subset.

Fuzzy Adaptive Control of Uncertain MIMO Chaotic Systems with Unknown Control Direction
Complexity, 2021 This paper presents an adaptive controller for MIMO chaotic systems with system uncertainties and unknown control direction. In the controller design, the matrix decomposition theory is used, and we decompose the control gain matrix into a positive ...

Efficient quantum circuits for diagonal unitaries without ancillas
New Journal of Physics, 2014 The accurate evaluation of diagonal unitary operators is often the most resource-intensive element of quantum algorithms such as real-space quantum simulation and Grover search.

Des espaces habités pas comme les autres
, 2020 À la campagne comme en ville, il est possible de penser autrement l’urbanisation. L’architecte-urbaniste Bernard Menguy en témoigne. Économes en foncier et riches en biodiversité, les opérations conçues en Ille-et-Vilaine réussissent à conjuguer charme ...

Pediatric Blood &Cancer, EarlyView.ABSTRACT Background Children with sickle cell anemia (SCA) in low‐income settings are at risk of severe malnutrition, but optimal nutritional management has not been established. We evaluated an intensified ready‐to‐use therapeutic food (RUTF) regimen in children with persistent severe malnutrition after initial treatment and assessed whether early ...
