On approximating functions of the singular values in a stream [PDF]
Proceedings of the forty-eighth annual ACM symposium on Theory of Computing, 2016 For any real number $p > 0$, we nearly completely characterize the space complexity of estimating $\|A\|_p^p = \sum_{i=1}^n σ_i^p$ for $n \times n$ matrices $A$ in which each row and each column has $O(1)$ non-zero entries and whose entries are presented one at a time in a data stream model. Here the $σ_i$ are the singular values of $A$, and when $p

A generalization of the randomized singular value decomposition
CoRR, 2021 The randomized singular value decomposition (SVD) is a popular and effective algorithm for computing a near-best rank $k$ approximation of a matrix $A$ using matrix-vector products with standard Gaussian vectors. Here, we generalize the randomized SVD to multivariate Gaussian vectors, allowing one to incorporate prior knowledge of $A$ into the ...

Robust normalization and guaranteed cost control for a class of uncertain singular Markovian jump systems via hybrid impulsive control [PDF]
, 2013 This paper investigates the problem of robust normalization and guaranteed cost control for a class of uncertain singular Markovian jump systems. The uncertainties exhibit in both system matrices and transition rate matrix of the Markovian chain.

Improved singular value inclusion sets for rectangular tensors
Journal of Inequalities and ApplicationsIn this paper, improved singular value inclusion sets for rectangular tensors are given, which are tighter than those in (Zhao and Li in Linear Multilinear Algebra 66(7):1333–1350, 2018).

Artificial molecular machines and motors—Design and control of nanoscale motion
FEBS Letters, EarlyView.Molecules are constantly moving because of thermal fluctuations, but random motion alone cannot be exploited to perform directional tasks. Artificial molecular machines use chemical, electrical, or light energy to bias this motion. Molecular shuttles, rotary motors, and supramolecular pumps illustrate how nanoscale movement can be controlled and ...

FEBS Letters, EarlyView.Heterodimeric amino acid transporters consist of SLC7 and SLC3 family proteins arranged in a conserved structural organization. They regulate nutrient transport across cell membranes, supporting essential cellular functions. These transporters also contribute to xenobiotic/drug uptake and distribution.

Perturbation of Higher-Order Singular Values [PDF]
SIAM Journal on Applied Algebra and Geometry, 2017 Summary: The higher-order singular values for a tensor of order \(d\) are defined as the singular values of the \(d\) different matricizations associated with the multilinear rank. When \(d \geq 3\), the singular values are generally different for different matricizations but not completely independent.
