Inverse modelling of European N₂O emissions: assimilating observations from different networks [PDF]

, 2010
We describe the setup and first results of an inverse modelling system for atmospheric N2O, based on a four-dimensional variational (4DVAR) technique and the atmospheric transport zoom model TM5. We focus in this study on the European domain, utilizing a

A class of singular Ro-matrices and extensions to semidefinite linear complementarity problems [PDF]

Yugoslav Journal of Operations Research, 2013
For ARnxn and qRn, the linear complementarity problem LCP(A, q) is to determine if there is xRn such that x ≥ 0; y = Ax + q ≥ 0 and xT y = 0. Such an x is called a solution of LCP(A,q).

Inverse scattering and the Geroch group [PDF]

Journal of High Energy Physics, 2013
We study the integrability of gravity-matter systems in D=2 spatial dimensions with matter related to a symmetric space G/K using the well-known linear systems of Belinski-Zakharov (BZ) and Breitenlohner-Maison (BM). The linear system of BM makes the group structure of the Geroch group manifest and we analyse the relation of this group structure to the

Gait Event Prediction Using Surface Electromyography in Parkinsonian Patients

Bioengineering, 2023
Gait disturbances are common manifestations of Parkinson’s disease (PD), with unmet therapeutic needs. Inertial measurement units (IMUs) are capable of monitoring gait, but they lack neurophysiological information that may be crucial for studying gait ...

M-matrix and inverse M-matrix extensions

Special Matrices, 2020
A class of matrices that simultaneously generalizes the M-matrices and the inverse M-matrices is brought forward and its properties are reviewed. It is interesting to see how this class bridges the properties of the matrices it generalizes and provides a

The group inverse of circulant matrices depending on four parameters

Special Matrices, 2021
Explicit expressions for the coefficients of the group inverse of a circulant matrix depending on four complex parameters are analytically derived. The computation of the entries of the group inverse are now reduced to the evaluation of a polynomial ...

Resistance Distance and Kirchhoff Index of $Q$ -Double Join Graphs

IEEE Access, 2019
Let Q(G) be the graph derived from G by inserting a new vertex into every edge of G and by connecting edges of these new vertices that are on adjacent edges of G, and Q-double join of G, G1 and G2 denoted by GQ v{G1, G2}, is the graph derived from Q(G ...

Unification of sparse Bayesian learning algorithms for electromagnetic brain imaging with the majorization minimization framework

NeuroImage, 2021
Methods for electro- or magnetoencephalography (EEG/MEG) based brain source imaging (BSI) using sparse Bayesian learning (SBL) have been demonstrated to achieve excellent performance in situations with low numbers of distinct active sources, such as ...

Automorphisms of the affine Cremona group [PDF]

, 2013
We show that every automorphism of the group Gn := Aut(An) of polynomial automorphisms of complex affine n-space An = Cn is inner up to field automorphisms when restricted to the subgroup TGn of tame automorphisms.
