Trees and Matchings

open access: yes, 1999
In this article, Temperley's bijection between spanning trees of the square grid on the one hand, and perfect matchings (also known as dimer coverings) of the square grid on the other, is extended to the setting of general planar directed (and undirected)

Adsorption and Separation by Flexible MOFs

open access: yesAdvanced Materials, EarlyView.
Flexible metal–organic frameworks (MOFs) present significant potential for gas storage and separation due to their structural dynamic. This review explores the rationale behind the flexible MOFs' enhanced working capacity and separation factors. It also addresses key challenges, including phase transition kinetics, crystal robustness, cycling, shaping,

Van Der Waals Hybrid Integration of 2D Semimetals for Broadband Photodetection

open access: yesAdvanced Materials, EarlyView.
Advanced broadband photodetector technologies are essential for military and civilian applications. 2D semimetals, with their gapless band structures, high mobility, and topological protection, offer great promise for broadband PDs. This study reviews the latest advancements in broadband PDs utilizing heterostructures that combine 2D semimetals with ...

First-order logic with metric betweenness – the case of non-definability of some graph classes

open access: yesAKCE International Journal of Graphs and Combinatorics
The metric betweenness of a connected graph and arbitrary graphs is FO definable. Moreover, several interesting classes of graphs with strong distance properties are shown to be FO definable using metric betweenness.

Distance perfectness of graphs

open access: yesDiscussiones Mathematicae Graph Theory, 1999
The author introduces a new generalization of perfect graphs. It turns out that the analogue of the weak perfect graph theorem is not true for this generalization. A subset \(Q\) of the vertex set \(V\) of a graph \(G\) is a \(k\)-distance clique in \(G\) if \(d_G(x,y)\leq k\) for any \(x,y\in Q\) and \(\langle Q\rangle_G\), the subgraph of \(G ...

Plaque‐Targeted Delivery of Fluoride‐Free MXene Nanozyme for Alleviating Atherosclerosis via Sonocatalytic Therapy

open access: yesAdvanced Materials, EarlyView.
This work has developed a dual enzyme‐mimicking and ultrasound‐responsive Nb2C‐Pt@HA‐PEG nanozyme. ROS‐eliminating and anti­inflammatory capability of Nb2C‐Pt@HA‐PEG under US irradiation are demonstrated on macrophages and endothelial cells in vitro. Nb2C‐Pt@HA‐PEG‐mediated sonocatalytic therapy exerts an outstanding anti‐atherosclerosis efficacy by ...

MUTE‐Seq: An Ultrasensitive Method for Detecting Low‐Frequency Mutations in cfDNA With Engineered Advanced‐Fidelity FnCas9

open access: yesAdvanced Materials, EarlyView.
An advanced‐fidelity CRISPR nuclease, FnCas9‐AF2, is rationally engineered to discriminate single‐base mismatches with unprecedented level precision. Integrated into the MUTE‐Seq workflow, FnCas9‐AF2 depletes wild‐type cell‐free DNA, thereby exposing rare tumor‐derived mutant DNA (a molecular “needle in a haystack”).

Core Index of Perfect Matching Polytope for a 2-Connected Cubic Graph

open access: yesDiscussiones Mathematicae Graph Theory, 2018
For a 2-connected cubic graph G, the perfect matching polytope P(G) of G contains a special point xc=(13,13,…,13)$x^c = \left( {{1 \over 3},{1 \over 3}, \ldots ,{1 \over 3}} \right)$ . The core index ϕ(P(G)) of the polytope P(G) is the minimum number of

PiP‐Plex: A Particle‐in‐Particle System for Multiplexed Quantification of Proteins Secreted by Single Cells

open access: yesAdvanced Materials, EarlyView.
Detecting proteins secreted by a single cell while retaining its viability remains challenging. A particles‐in‐particle (PiPs) system made by co‐encapsulating barcoded microparticles (BMPs) with a single cell inside an alginate hydrogel particle is introduced.
