Engineering Lipid Nanoparticles for Precision RNA Delivery: Design Principles, Targeting Strategies, and Clinical Prospects

open access: yesCancer Nexus, Volume 2, Issue 2, April 2026.
ABSTRACT Lipid nanoparticles (LNPs) represent the most clinically advanced platform for RNA delivery and have enabled major breakthroughs in vaccines and gene therapies. However, their broader application is still limited by inefficient extrahepatic delivery, immunogenicity, and insufficient control over tissue‐ and cell‐specific targeting. This review

Hausdorff dimension of double‐base expansions and binary shifts with a hole

open access: yesBulletin of the London Mathematical Society, Volume 58, Issue 4, April 2026.
Abstract For two real bases q0,q1>1$q_0, q_1 > 1$, a binary sequence i1i2⋯∈{0,1}∞$i_1 i_2 \cdots \in \lbrace 0,1\rbrace ^\infty$ is the (q0,q1)$(q_0,q_1)$‐expansion of the number πq0,q1(i1i2⋯)=∑k=1∞ikqi1⋯qik.$$\begin{equation*} \pi _{q_0,q_1}(i_1 i_2 \cdots) = \sum _{k=1}^\infty \frac{i_k}{q_{i_1} \cdots q_{i_k}}.

Topological entropy of the induced maps of the inverse limits with bonding maps

open access: yes, 1995
We generalize a result of Bowen by showing that the topological entropy of the induced map of the inverse limit space with bonding maps is equal to the limit of the topological entropy of the original maps. As an application we prove that the topological

On the Measure of Maximal Entropy for Finite Horizon Sinai Billiard Maps

open access: yes, 2023
The Sinai billiard map $T$ on the two-torus, i.e., the periodic Lorentz gas, is a discontinuous map. Assuming finite horizon, we propose a definition $h_*$ for the topological entropy of $T$. We prove that $h_*$ is not smaller than the value given by the

Neural Mechanisms of Shooting Preparation Under High‐Risk and High‐Precision Tasks: A Multiscale EEG Study

open access: yesBrain and Behavior, Volume 16, Issue 3, March 2026.
This study investigated the neural mechanisms underlying the shooting preparation phase in 30 shooters across three task conditions, with concurrent collection of shooting performance metrics and self‐report measures. The findings revealed that during high‐pressure shooting tasks (Hostage‐Rescue and Long‐Range), shooters experienced significantly ...
