The importin‐alpha superfamily engages in ethylene signaling by shuttling ETHYLENE INSENSITIVE 2 from the endoplasmic reticulum to the nucleus

The FEBS Journal, EarlyView.
The plant hormone ethylene regulates plant growth, ripening, senescence, and stress responses. The hormonal signal transmission, from receptors at the ER membrane to the transcriptional regulators in the nucleus, is still not completely understood.

Bipartite Tracking Consensus Control of Nonlinear High-Order Multi-Agent Systems Subject to Exogenous Disturbances

IEEE Access, 2019
This study concentrates on the bipartite tracking consensus for nonlinear high-order multi-agent systems(MASs) subject to exogenous disturbances over a signed directed graph. First, under the condition of nonlinear dynamics, two new control protocols are

Beyond Deception: What Else Do Flower Wasps (Hymenoptera: Thynnidae: Thynninae) Do in Flowers Worldwide?

Journal of Applied Entomology, EarlyView.
ABSTRACT Wasps, although less recognised as good pollinators, also feed on nectar and pollinate flowers. Specialised pollination systems, such as orchids that mimic the pheromones of female wasps to attract males, are complex and specific. This interaction occurs with some Thyninnae wasps that also visit flowers to obtain nectar and perform other ...

Computing the permanental polynomial of 4k-intercyclic bipartite graphs

The American Journal of Combinatorics
Let \(G\) be a bipartite graph with adjacency matrix \(A(G)\). The characteristic polynomial \(\phi(G,x)=\det(xI-A(G))\) and the permanental polynomial \(\pi(G,x) = \operatorname{per}(xI-A(G))\) are both graph invariants used to distinguish graphs.

Automated path‐planning strategy for robotic inspection of underground utilities based on building information model

Computer-Aided Civil and Infrastructure Engineering, EarlyView.
Abstract This paper proposes a fully automated end‐to‐end inspection‐path‐planning strategy for underground utilities, such as pipelines, based on building information modeling (BIM). An automatic extraction method is developed to process utility information from BIM models, using a registration step that pairs each pipeline with its corresponding ...

Quasi-Irreducibility of Nonnegative Biquadratic Tensors

Mathematics
While the adjacency tensor of a bipartite 2-graph is a nonnegative biquadratic tensor, it is inherently reducible. To address this limitation, we introduce the concept of quasi-irreducibility in this paper.

哈林图的偶匹配可扩性(Bipartite matching-extendability of Halin graphs)

Zhejiang Daxue xuebao. Lixue ban, 2009
Let G be a connected graph containing a perfect matching. G is said to be bipartite matching extendable if every matching M of G whose induced subgraph is a bipartite matching extends to a perfect matching of G. The main result is as follows: Halin graph
