An Online Semi-Definite Programming with a Generalized Log-Determinant Regularizer and Its Applications

open access: yesMathematics, 2022
We consider a variant of the online semi-definite programming problem (OSDP). Specifically, in our problem, the setting of the decision space is a set of positive semi-definite matrices constrained by two norms in parallel: the L∞ norm to the diagonal ...

The symmetric N-matrix completion problem

open access: yesLinear Algebra and its Applications, 2005
A real \(n\times n\) matrix is called an \(N\)-matrix if all its principal minors are negative. Consider a partial symmetric matrix \(A\) where some entries are unspecified. The problem under consideration is whether it is possible to determine these unspecified entries in such a way that the resulting fully specified symmetric matrix is an \(N ...

The nonnegative Q−matrix completion problem

open access: yesJournal of Algebra Combinatorics Discrete Structures and Applications, 2017
Summary: In this paper, the nonnegative \(Q\)-matrix completion problem is studied. A real \(n\times n\) matrix is a \(Q\)-matrix if for \(k\in \{1,\dots, n\}\), the sum of all \(k \times k\) principal minors is positive. A digraph \(D\) is said to have nonnegative \(Q\)-completion if every partial nonnegative \(Q\)-matrix specifying \(D\) can be ...

Correntropy Based Matrix Completion

open access: yesEntropy, 2018
This paper studies the matrix completion problems when the entries are contaminated by non-Gaussian noise or outliers. The proposed approach employs a nonconvex loss function induced by the maximum correntropy criterion.

Recurrent cancer‐associated ERBB4 mutations are transforming and confer resistance to targeted therapies

open access: yesMolecular Oncology, EarlyView.
We show that the majority of the 18 analyzed recurrent cancer‐associated ERBB4 mutations are transforming. The most potent mutations are activating, co‐operate with other ERBB receptors, and are sensitive to pan‐ERBB inhibitors. Activating ERBB4 mutations also promote therapy resistance in EGFR‐mutant lung cancer.

The nonnegative P_0-matrix completion problem

open access: yesThe Electronic Journal of Linear Algebra, 2003
Let \({\mathcal N}= \{1,2,\dots,n\}\) and \(Q\) be a subset of \({\mathcal N}\times{\mathcal N}\). The digraph of \(Q\) is the digraph having vertex set \({\mathcal N}\) and as arcs, the ordered pairs \((i,j)\in Q\) where \(i\neq j\). Assume that \((i,i)\in Q\) for all \(i\in{\mathcal N}\).

Rethinking plastic waste: innovations in enzymatic breakdown of oil‐based polyesters and bioplastics

open access: yesFEBS Open Bio, EarlyView.
Plastic pollution remains a critical environmental challenge, and current mechanical and chemical recycling methods are insufficient to achieve a fully circular economy. This review highlights recent breakthroughs in the enzymatic depolymerization of both oil‐derived polyesters and bioplastics, including high‐throughput protein engineering, de novo ...
