PBW-degenerated Demazure modules and Schubert varieties for triangular elements [PDF]

open access: yes, 2016
We study certain faces of the normal polytope introduced by Feigin, Littelmann and the author whose lattice points parametrize a monomial basis of the PBW-degenerated of simple modules for sln+1.

Beyond Fourier [PDF]

open access: yesJournal of Magnetic Resonance, 2017
Non-Fourier methods of spectrum analysis are gaining traction in NMR spectroscopy, driven by their utility for processing nonuniformly sampled data. These methods afford new opportunities for optimizing experiment time, resolution, and sensitivity of multidimensional NMR experiments, but they also pose significant challenges not encountered with the ...

Investigating the Stationarity Properties of Oil Consumption: an Empirical Analysis for OECD Countries

open access: yesİktisat Politikası Araştırmaları Dergisi, 2022
In a changing and developing world, production activities are dependent on energy resources. A significant part of the energy needed in the world is obtained from fossil fuels.

Degree cones and monomial bases of Lie algebras and quantum groups [PDF]

open access: yes, 2016
We provide $\mathbb{N}$-filtrations on the negative part $U_q(\mathfrak{n}^-)$ of the quantum group associated to a finite-dimensional simple Lie algebra $\mathfrak{g}$, such that the associated graded algebra is a skew-polynomial algebra on $\mathfrak{n}

A reduction principle for Fourier coefficients of automorphic forms [PDF]

open access: yes, 2020
In this paper we analyze a general class of Fourier coefficients of automorphic forms on reductive adelic groups $\mathbf{G}(\mathbb{A}_\mathbb{K})$ and their covers.

Digital Fourier optics [PDF]

open access: yesApplied Optics, 1996
Analog Fourier optical processing systems can perform important classes of signal processing operations in parallel, but suffer from limited accuracy. Digital-optical equivalents of such systems could be built that share many features of the analog systems while allowing greater accuracy.

Application of Shape Analyses to Recording Structures of Marine Organisms for Stock Discrimination and Taxonomic Purposes

open access: yesFrontiers in Marine Science, 2021
Morphometric analysis of biogenic recording structures within marine organisms has applications in stock assessment, taxonomics, and ecomorphological studies, with shape variation markedly influenced by both genetics and the surrounding environment ...

Improvement of broadband seismic station installations at the Observatoire de Grenoble (OSUG) seismic network [PDF]

open access: yesAdvances in Geosciences, 2013
We describe in this paper different improvements that were brought to the installation of seismic broadband stations deployed by the Observatoire de Grenoble (OSUG) in the northern French Alps.

Schur Positivity and Kirillov-Reshetikhin Modules [PDF]

open access: yes, 2014
In this note, inspired by the proof of the Kirillov-Reshetikhin conjecture, we consider tensor products of Kirillov-Reshetikhin modules of a fixed node and various level.
