U.S. health officials have changed their advice to international travelers about measles,
saying that Americans should be vaccinated against the virus
-- no matter where they’re going.
U.S. residents are recommended to get measles-mumps-rubella shots, anyway.
But the Centers for Disease Control and Prevention previously emphasized the importance of vaccination for travelers going to countries with outbreaks.

All international travelers should get measles vaccinations, CDC says
U.S. health officials have changed their advice to international travelers about measles, saying Americans should be vaccinated against the disease no matter where they travel in the world. U.S. residents are recommended to get measles-mumps-rubella shots, anyway. But the Centers for Disease Control and Prevention previously emphasized the importance of vaccination for travelers going to countries with outbreaks. Last week, the CDC updated its guidance to call for vaccinations for travelers goi…

Complete universal scaling of first-order phase transitions in the two-dimensional Ising model
Phase transitions, as one of the most intriguing phenomena in nature, are divided into first-order phase transitions (FOPTs) and continuous ones in current classification. While the latter shows striking phenomena of scaling and universality, the former has recently also been demonstrated to exhibit scaling and universal behavior within a mesoscopic, coarse-grained Landau-Ginzburg theory. Here we apply this theory to a microscopic model -- the paradigmatic Ising model, which undergoes FOPTs bet…

An elementary proof of a criterion for subfunctors of Ext to be closed
Let $\mathcal{A}$ be an abelian category and let $F$ be a subbifunctor of the additive bifunctor $\text{Ext}_{\mathcal{A}}^{1}(-,-)\colon \mathcal{A}^{\text{op}}\times \mathcal{A}\to \mathsf{Ab}$. Buan proved in [4] that $F$ is closed if, and only if, $F$ has the $3\times 3$-lemma property, a certain diagrammatic property satisfied by the class of $F$-exact sequences. The proof of this result relies on the theory of exact categories and on the Freyd--Mitchell embedding theorem, a very well-know…

BDPFL: Backdoor Defense for Personalized Federated Learning via Explainable Distillation
Federated learning is a distributed learning paradigm that facilitates the collaborative training of a global model across multiple clients while preserving the privacy of local datasets. To address inherent challenges related to data heterogeneity and satisfy personalized needs, a new direction within FL, known as personalized Federated Learning (pFL), has gradually evolved. Extensive attention has been directed toward developing novel frameworks and methods to enhance the performance of pFL. …

Development of Hardware-in-Loop Framework for Satellite Communication Self-Healing Networks
The use of Low Earth Orbit (LEO) satellites in the next generation (Next-G) communication systems has been gaining traction over the last few years due to their potential for providing global connectivity with low latency. Since they are the closest to the earth they come with their own set of disadvantages including high vulnerability to jamming and interference. To address these issues, this paper introduces a resilient, self-healing network designed to optimize signal quality under dynamic i…

Persistence of charge ordering instability to Coulomb engineering in the excitonic insulator candidate TiSe$_2$
TiSe$_2$ has long been considered one of the best candidate materials to host the elusive excitonic insulator (EI) phase. However, a finite coupling to the lattice can generically be expected, while a lack of "smoking-gun" signatures for the importance of the electron-hole interaction in driving the phase transition has rendered it challenging to distinguish the EI from the conventional charge-density-wave (CDW) phase. Here, we demonstrate a new approach, exploiting the susceptibility of excito…
