I, an atheist, would defend these Christians from persecution.
The MAGA regime, ostensibly Christian nationalists, are the persecutors.

ICE Goes After Church Leaders and Christians Fleeing Persecution
On Tuesday, Iranian asylum-seekers were detained in Los Angeles, adding to the count of church members taken despite lawful status.

I rarely leave my neighborhood these days, so when the opportunity came last weekend to visit a town about 80 km from my home, I took a little detour to visit and take photos of the town’s only national historical marker.

Tänk er ett samtal där du ställer en fråga, får ett svar och sen lägger personen på. Har den missförstått frågan måste du starta ett nytt samtal, men den som svarar denna gång vet inte varför du fick det svar du fick förra gången och svarar helt sonika någonting annat... och lägger på.
Låter det frustrerande?
Det är det!
Öppnar mitt tredje 'samtal' med denna text - är jag för hård?

Legendrian doubles, twist spuns, and clusters

Legendrian doubles, twist spuns, and clusters
Let $λ$ be a Legendrian link in standard contact $\mathbb{R}^3$, such that $L_1$, $L_2$ are two exact fillings of $λ$ and $φ$ is a Legendrian loop of $λ$. We study fillability and isotopy characterizations of Legendrian surfaces in standard contact $\mathbb{R}^5$ built from the above data by doubling or twist spinning; denoting them $Λ(L_1,L_2)$ or $Σ_φ(λ)$ respectively. In the case of doubles $Λ(L_1,L_2)$, if the sheaf moduli $\mathcal{M}_1(λ)$ admits a cluster structure, we introduc…

The Persistence of Nonlinear Gravitational Wave Memory
Nonlinear gravitational wave memory is a surprise of theoretical physics. Whereas it is understood that a gravitational wave induces oscillatory squeezing and stretching motion in a collection of freely-falling test masses, it is unexpected that the wave leaves a residual displacement of the test masses. This displacement is the tribute in memoriam to the passing wave. The memory originates in a nonlinear feature of gravitation. Whilst merging black holes are a significant source of gravitation…

Pretty sure my mom gets that “flying-an-airplane-without-a-manual” feeling whenever she walks in and catches sight of my anarchist flag waving next to the rainbow, trans, and neurodiversity pride flags.

Online Adaptation for Flying Quadrotors in Tight Formations
The task of flying in tight formations is challenging for teams of quadrotors because the complex aerodynamic wake interactions can destabilize individual team members as well as the team. Furthermore, these aerodynamic effects are highly nonlinear and fast-paced, making them difficult to model and predict. To overcome these challenges, we present L1 KNODE-DW MPC, an adaptive, mixed expert learning based control framework that allows individual quadrotors to accurately track trajectories while …

Spike layered solutions for elliptic systems on Riemannian Manifolds
In this article, we study the following Hamiltonian system: \begin{equation*} \begin{cases} \begin{aligned} &-\varepsilon^{2}Δ_{g} u +u = |v|^{q-1}v, &-\varepsilon^{2}Δ_{g} v +v = |u|^{p-1}u && \text{ in } \mathcal{M}, & \quad u,v >0 && \text{ in } \mathcal{M}, \end{aligned} \end{cases} \end{equation*} where $\mathcal{M}$ is a smooth, compact and connected Riemannian manifold of dimension $N\geq 3$ without boundary. The exponents $p,q>1$ are assumed to lie be…
