Love the new #Mastodon 4.4 pinned post pagination... though I think I would like it to auto advance. even if slow.

Mastodon 4.4 is out now,
and it brings changes for profiles and lists and also lays the groundwork for quote posts.
With #profiles, you can feature specific hashtags so that people can see all the posts you’ve tagged with those hashtags.
Mastodon is also making a change to how #pinned posts work: you can…

Pinned distances and density theorems in $\mathbb R^d$

Pinned distances and density theorems in $\mathbb R^d$
We study a pinned variant of Bourgain's theorem, concerning the occurrence of affine copies of $k$-point patterns in $\mathbb{R}^d$. Focusing on the case $k=2$, which corresponds to pinned distances, we show that the classical conclusion does not extend to the pinned setting: there exist sets of positive upper density in $\mathbb{R}^d$, $d \geq 2$, such that no single pinned point determines all sufficiently large distances. However, we establish a weaker quantitative result: for every point $x…

New Molecular Dynamics Methods for Simulating Neutron Star Crusts with Superfluid Vortices
Superfluid vortices in neutron star crusts are thought to be pinned to the lattice of nuclei in the crust. The unpinning of superfluid vortices in spin glitches therefore motivates us to study the vortex-crust interaction explicitly with molecular dynamics. In this work, we present a new molecular dynamics methods to characterize the response of the crust to a rigid vortex. When vortex pinning forces and nearest neighbor Coulomb forces are comparable, we observe a qualitatively new phenomena of…

Toxic Thailand rivers pinned on Myanmar mines
A sprawling new mine is gouged into the lush rolling hills of northeast Myanmar, where civil war has weakened the government's already feeble writ, and pollution levels are rising downstream in Thailand.

Macroscopic entanglement between localized domain walls inside a cavity
We present a scheme for generating stable and tunable entanglement between two localized Bloch domain walls in nanomagnetic strips kept inside a chiral optical cavity. The entanglement is mediated by the effective optomechanical interaction between the cavity photons and the two macroscopic, collective modes of the pinned domain walls. By controlling the pinning potential and optical driving frequency, the robust, steady-state entanglement between the two macroscopic domain walls can survive be…

Periodically Driven anharmonic chain: Convergent Power Series and Numerics
We investigate the long time behavior of a pinned chain of $2N+1$ oscillators, indexed by $x \in\{-N,\ldots, N\}$. The system is subjected to an external driving force on the particle at $x=0$, of period $θ=2π/ω$, and to frictional damping $γ>0$ at both endpoints $x=-N$ and $N$. The oscillators interact with a pinned and nearest neighbor harmonic plus anharmonic potentials of the form $\frac{ω_0^2 q_x^2}{2}+\frac12 (q_{x}-q_{x-1})^2 +ν\left[V(q_x)+U(q_x-q_{x-1}) \right]$, with $…

I have an admission to make.
I made a Facebook account. 😭😬
Before you draw and quarter me, please understand this is out of pure desperation/necessity. lol.
Our town only buys/sells things on Marketplace. I don’t want to keep bugging my spouse every time I need to sell something (which isn't very often thankfully) or want to look for some random used thing.
The final straw was having to sell our son's car now that he has moved away.
My punishment: even though I pinned a post on my FB profile saying I am only using it for Marketplace and won't be accepting any Friend requests and that everyone should definitely check out the Free and Open web at socialbc.ca… now I am getting friend requests and feel slightly guilty.
I don't want to confirm them, obviously, but also don't want to delete them because that seems rude.
God I hate how FB has monopolized this stuff!
On the bright side, someone is coming to buy the car today!

Stability of flat-core pinned p-elasticae
We classify the stability of flat-core $p$-elasticae in $\mathbf{R}^d$ subject to the pinned boundary condition. Together with previous work, this completes the classification of stable pinned $p$-elasticae in $\mathbf{R}^d$ for all $p\in(1,\infty)$ and $d\geq2$.

Youtube comment handling is so annoying.
HRCC talked about Field Day, including some mention of CW. So I mentioned my Morse Walker Field Day simulator work, and Josh pinned my comment.
I have now twice posted followup comments mentioning QRZ and my call sign, hoping that people can find the simulator from my QRZ page, without posting a link, and Youtube keeps silently deleting the comments. Argh.
I have no idea what it is triggering on.

First critical field in the pinned three dimensional Ginzburg-Landau model of superconductivity
We study extreme type-II superconductors described by the three dimensional magnetic Ginzburg-Landau functional incorporating a pinning term $a_\varepsilon(x)$, which we assume to be a bounded measurable function satisfying $b\leq a_\varepsilon(x)\leq 1$ for some constant $b>0$. A hallmark of such materials is the formation of vortex filaments, which emerge when the applied magnetic field exceeds the first critical field $H_{c_1}$. In this work, we provide a lower bound for this critical field …

Dynamics of low-mass black hole seeds in the BRAHMA simulations using subgrid-dynamical friction: Impact on merger-driven black hole growth in the high redshift Universe
We analyze the dynamics of low-mass black hole (BH) seeds in the high-redshift ($z\gtrsim5$) Universe using a suite of $[4.5~\mathrm{Mpc}]^3$ and $[9~\mathrm{Mpc}]^3$ BRAHMA cosmological hydrodynamic simulations. The simulations form seeds with mass $M_{\mathrm{seed}}=2.2\times10^3~M_{\odot}$ in halos that exceed critical thresholds of dense & metal-poor gas mass ($5-150~M_{\mathrm{seed}}$) and the halo mass ($1000-10000~M_{\mathrm{seed}}$). While the initial BRAHMA boxes pinned the BHs to the …

Light-induced localized vortices in multicomponent Bose-Einstein condensates
We study continuous interaction of a trapped two-component Bose-Einstein condensate with light fields in a $Λ$-type configuration. Using light beams with orbital angular momentum, we theoretically show how to create a stable, pinned vortex configuration, where the rotating component is confined to the region surrounded by the second, non-rotating component. The atoms constituting this vortex can be localized in volumes much smaller than the volume occupied by the second component. The position…

Anomalous Critical Behavior of Driven Disordered Systems Beyond the Overdamped Limit
We investigate the role of relaxation mechanisms in the driven response of elastic disordered interfaces in finite dimensions, focusing on the interplay between dimensionality and interaction range. Through extensive numerical simulations, we identify two distinct dynamical regimes. In two-dimensional systems with long-range interactions, we observe a regime of coexistence between pinned and flowing states. In contrast, for one-dimensional interfaces with long-range elasticity, as well as for s…

Hey, I’m Erik. I’m an anarchist with an embarrassingly massive crush on Rudolf Rocker’s syndicalist take. I’m also bisexual, autistic, and genderfluid because why not add some extra flavor?
