Time, the final frontier

Molecular Oncology, EarlyView.
This article advocates integrating temporal dynamics into cancer research. Rather than relying on static snapshots, researchers should increasingly consider adopting dynamic methods—such as live imaging, temporal omics, and liquid biopsies—to track how tumors evolve over time.

The -annihilating-ideal hypergraph of commutative ring

AKCE International Journal of Graphs and Combinatorics, 2019
The concept of the annihilating-ideal graph of a commutative ring was introduced by Behboodi et. al in 2011. In this paper, we extend this concept to the hypergraph for which we define an algebraic structure called -annihilating-ideal of a commutative ...

An SPQR-Tree-Like Embedding Representation for Level Planarity [PDF]

arXiv, 2020
An SPQR-tree is a data structure that efficiently represents all planar embeddings of a biconnected planar graph. It is a key tool in a number of constrained planarity testing algorithms, which seek a planar embedding of a graph subject to some given set of constraints.

Planar Prior Assisted PatchMatch Multi-View Stereo [PDF]

AAAI Conference on Artificial Intelligence, 2019
The completeness of 3D models is still a challenging problem in multi-view stereo (MVS) due to the unreliable photometric consistency in low-textured areas.

HDAC4 regulates apoptosis in Acan‐CreERT2;HDAC4d/d mice with osteoarthritis by downregulating ATF4

FEBS Open Bio, EarlyView.
Using the AcanCreERT2;HDAC4fl/fl genetic mouse model, we further investigated the role of histone deacetylase 4 (HDAC4) in chondrocyte apoptosis. We found that knocking down HDAC4 may be associated with chondrocyte apoptosis by upregulating the activating transcription factor 4 (ATF4)/CAAT/enhancer binding protein homologous (CHOP) signaling pathway ...

Kernels in planar digraphs

Journal of Computer and System Sciences, 2005
AbstractA set S of vertices in a digraph D=(V,A) is a kernel if S is independent and every vertex in V-S has an out-neighbor in S. We show that there exist O(n219.1k+n4)-time and O(k36+219.1kk9+n2)-time algorithms for checking whether a planar digraph D of order n has a kernel with at most k vertices.

The Continuum Between Hexagonal Planar and Trigonal Planar Geometries

Angewandte Chemie, 2022
New heterometallic hydride complexes that involve the addition of {Mg–H} and {Zn–H} bonds to group 10 transition metals (Pd, Pt) are reported. The side-on coordination of a single {Mg–H} to Pd forms a well-defined σ-complex. In contrast, addition of three {Mg–H} or {Zn–H} bonds to Pd or Pt results in the formation of planar complexes with subtly ...

Identification of inhibitors of the Salmonella FraB deglycase, a drug target

FEBS Open Bio, EarlyView.
A high‐throughput screen was used to identify inhibitors of Salmonella FraB, a drug target. Characterization of top hits (identified after an additional counter screen) revealed that some triazolidines, thiadiazolidines, and triazolothiadiazoles are mixed‐type inhibitors of FraB.

Maximum Upward Planar Subgraphs of Embedded Planar Digraphs [PDF]

Computational Geometry, 2008
AbstractLet G be an embedded planar digraph. A maximum upward planar subgraph of G is an embedding preserving subgraph that is upward planar and, among those, has the maximum number of edges. This paper presents an extensive study on the problem of computing maximum upward planar subgraphs of embedded planar digraphs: Complexity results, algorithms ...
