A Holistic Platform Approach for Developing Robust Pulmonary mRNA Delivery: Integrating Novel Phenolic Acid‐Derived Ionizable Lipids and Device Engineering

Advanced Functional Materials, EarlyView.
An integrated pulmonary mRNA delivery platform combining novel biodegradable syringic acid‐derived ionizable lipids, design‐of‐experiments formulation optimization, and vibrating‐mesh nebulizer engineering enabled stable aerosolization and efficient lung delivery.

Vertex Degree Weighted Path Indices

Acta Chimica Slovenica, 2016
Vertex degree weighted path indices P(N)(a, b, ...), for example P(1)(a, b), P(2)(a, b, c), P(3)(a, b, c, d), and P(4)(a, b, c, d, e), are good topological indices for some of the physicochemical properties of octanes with |R|(max) up to 0.999. Mutually optimized combinations of them are even better, R (P(1)..P(4)) is in the worst tested case > 0.9 ...

In Situ Magnetic Ordering and Microfabrication of Liquid Crystal Networks with Discretized Alignment

Advanced Functional Materials, EarlyView.
Miniaturizing liquid crystal network actuators typically demands costly laser writing or digital light processing. A low‐cost photolithography platform couples rotating photomasks with a Halbach magnetic array to discretize in‐plane molecular alignment down to 50 µm, producing programmable, light‐responsive grippers, checkerboards, and origami‐inspired

Limit distributions of the number of vertices with given degree in a conditional configuration graph

Transactions of the Karelian Research Centre of the Russian Academy of Sciences, 2016
We consider configuration graphs with N vertices. The degrees of the vertices are independent identically distributed random variables according to power-law distribution. Node degrees form semiedges that are numbered in an arbitrary order.

Limits to the Hall Effect and Other Nonreciprocal Effects in Three‐Dimensional Metamaterials

Advanced Materials, EarlyView.
Comprehensive and fundamental bounds on nonreciprocal effects in three‐dimensional metamaterials are derived. They reveal that the effective Hall mobility cannot exceed the largest constituent mobility, that, under certain conditions, the Verdet constant cannot be enhanced, and that, for constituents with Hall coefficients of the same sign, the largest

On the chromatic number of graphs with some restriction of vertex degrees

Учёные записки Казанского университета: Серия Физико-математические науки, 2020
Graphs, for which the degree of a certain vertex is equal to (d + 1) and the degrees of all other vertices are at most d , d ≥ 3 , were considered. Properties were obtained to color vertices of these graphs in d colors.

Weak In‐Plane Ferromagnetism and Electronic Nematicity in the Distorted Triple‐Q Magnetic Phase of Co1/3TaS2

Advanced Materials, EarlyView.
Co1/3TaS2${\rm Co}_{1/3}{\rm TaS}_{2}$ hosts a triple‐Q noncoplanar antiferromagnetic state with coexisting Z3${\rm Z}_3$ electronic nematicity. We report rotational hysteresis observed in both magnetoresistance and magnetic torque, revealing strongly pinned in‐plane weak ferromagnetic moments in the triple‐Q phase and the magnetism‐driven nature of ...

A Note on the Minimum Wiener Polarity Index of Trees with a Given Number of Vertices and Segments or Branching Vertices

Discrete Dynamics in Nature and Society, 2021
The Wiener polarity index of a graph G, usually denoted by WpG, is defined as the number of unordered pairs of those vertices of G that are at distance 3. A vertex of a tree with degree at least 3 is called a branching vertex.

A Thickness-Invariant Origami Robot With Integrated Actuation and Multimodal Locomotion. [PDF]

Adv Sci (Weinh)
A thickness‐invariant variation on the Yoshimura origami pattern is used as the basis of a robot, allowing power, actuation, and control systems to be embedded within the thickened panels of the pattern. The robot uses multiple kinematic branches to achieve distinct modes of locomotion, such as walking, running, galloping, and turning. ABSTRACT Origami
