Embedding almost-complex manifolds in almost-complex euclidean spaces [PDF]

, 2011
We show that any compact almost-complex manifold (M, J) of complex dimension m can be pseudo-holomorphically embedded in R6m equipped with a suitable almost-complex structure

Greedy routing and virtual coordinates for future networks [PDF]

, 2012
At the core of the Internet, routers are continuously struggling with ever-growing routing and forwarding tables. Although hardware advances do accommodate such a growth, we anticipate new requirements e.g.

Quantifying soil complexity using network models of soil porous structure [PDF]

Nonlinear Processes in Geophysics, 2013
This paper describes an investigation into the properties of spatially embedded complex networks representing the porous architecture of soil systems. We suggest an approach to quantify the complexity of soil pore structure based on the node-node link ...

Discrete embedding for attributed graphs

, 2022
Attributed graphs refer to graphs where both node links and node attributes are observable for analysis. Attributed graph embedding enables joint representation learning of node links and node attributes.

Weakly compact embedding of non-commutative symmetric spaces [PDF]

E-Journal of Analysis and Applied Mathematics
In this paper, we prove that the embeddings of certain well-known symmetric spaces are weakly compact. Our main results concern noncommutative Lorentz and Marcinkiewicz spaces on finite von Neumann algebras.

Task-Optimized Word Embeddings for Text Classification Representations

Frontiers in Applied Mathematics and Statistics, 2020
Word embeddings have introduced a compact and efficient way of representing text for further downstream natural language processing (NLP) tasks. Most word embedding algorithms are optimized at the word level.

Radial solutions of inhomogeneous fourth order elliptic equations and weighted Sobolev embeddings

Advances in Nonlinear Analysis, 2015
We deal with a class of inhomogeneous elliptic problems involving the biharmonic operator Δ2u + V(|x|)|u|q-2u = Q(|x|)f(u), u ∈ D02,2(ℝN), where Δ2 is the biharmonic operator and V, Q are singular continuous functions.

Sharpened Adams Inequality and Ground State Solutions to the Bi-Laplacian Equation in ℝ4

Advanced Nonlinear Studies, 2018
In this paper, we establish a sharp concentration-compactness principle associated with the singular Adams inequality on the second-order Sobolev spaces in ℝ4{\mathbb{R}^{4}}.

THz Characterization and Modeling of SiGe HBTs: Review (Invited)

IEEE Journal of the Electron Devices Society, 2020
This article presents a state-of-art review of on-wafer S-parameter characterization of THz silicon transistors for compact modelling purpose. After, a brief review of calibration/de-embedding techniques, the paper focuses on the on-wafer calibration ...
