Sparse Gradient Based Structured Matrix Decomposition for Salient Object Detection
IEEE Access, 2018 In the salient object detection, the given image can be decomposed into background regions (low-rank part) and salient regions (sparse part). In this paper, we present a novel sparse gradient-based structured matrix decomposition model for salient object

A tale of two airfoils: resolvent-based modelling of an oscillator vs. an amplifier from an experimental mean [PDF]
, 2019 The flows around a NACA 0018 airfoil at a Reynolds number of 10250 and angles of attack of alpha = 0 (A0) and alpha = 10 (A10) are modelled using resolvent analysis and limited experimental measurements obtained from particle image velocimetry.

Dynamic Substructuring of Damped Structures Using Singular Value Decomposition [PDF]
Journal of Applied Mechanics, 1997 This paper deals with the theoretical aspects concerning linear elastodynamic of damped continuum medium in the frequency domain. Eigenvalue analysis and frequency response function are studied. The methods discussed here use a dynamic substructuring approach.

A constructive arbitrary-degree Kronecker product decomposition of tensors [PDF]
, 2016 We propose the tensor Kronecker product singular value decomposition~(TKPSVD) that decomposes a real $k$-way tensor $\mathcal{A}$ into a linear combination of tensor Kronecker products with an arbitrary number of $d$ factors $\mathcal{A} = \sum_{j=1}^R ...

The newfound relationship between extrachromosomal DNAs and excised signal circles
FEBS Letters, EarlyView.Extrachromosomal DNAs (ecDNAs) contribute to the progression of many human cancers. In addition, circular DNA by‐products of V(D)J recombination, excised signal circles (ESCs), have roles in cancer progression but have largely been overlooked. In this Review, we explore the roles of ecDNAs and ESCs in cancer development, and highlight why these ...

µ−Values for Matrices Corresponding to Symmetries in Control Systems
International Journal of Analysis and Applications, 2018 In this article we consider numerical approximation of structured singular values ($\mu-$values). The lower bounds for $\mu-$values are approximated by using ordinary differential equations based technique.

Structural biology of ferritin nanocages
FEBS Letters, EarlyView.Ferritin is a conserved iron‐storage protein that sequesters iron as a ferric mineral core within a nanocage, protecting cells from oxidative damage and maintaining iron homeostasis. This review discusses ferritin biology, structure, and function, and highlights recent cryo‐EM studies revealing mechanisms of ferritinophagy, cellular iron uptake, and ...

Initial Layer Analysis for a Linkage Density in Cell Adhesion Mechanisms★
ESAIM: Proceedings and Surveys, 2018 In this paper we present a non local age structured equation involved in cell motility modeling [5, 9, 11]. It describes the evolution of a density of linkages of a point submitted to adhesion.

The Structured Singular Value for Linear Input/Output Operators [PDF]
SIAM Journal on Control and Optimization, 1996 The authors employ their lifting method [\textit{H. Bercovici}, \textit{C. Foias}, \textit{P. P. Khargonekar} and \textit{A. Tannenbaum}, J. Math. Anal. Appl. 187, 617-627 (1994; Zbl 0808.93018)] to study the structured singular value applied to input/output operators of control systems. Let \(A\) be a linear operator on a Hilbert space \({\mathcal E}\)

LDAcoop: Integrating non‐linear population dynamics into the analysis of clonogenic growth in vitro
Molecular Oncology, EarlyView.Limiting dilution assays (LDAs) quantify clonogenic growth by seeding serial dilutions of cells and scoring wells for colony formation. The fraction of negative wells is plotted against cells seeded and analyzed using the non‐linear modeling of LDAcoop.
