Not Here, Go There: Analyzing Redirection Patterns on the Web
URI redirections are integral to web management, supporting structural changes, SEO optimization, and security. However, their complexities affect usability, SEO performance, and digital preservation. This study analyzed 11 million unique redirecting URIs, following redirections up to 10 hops per URI, to uncover patterns and implications of redirection practices. Our findings revealed that 50% of the URIs terminated successfully, while 50% resulted in errors, including 0.06% exceeding 10 hops. …

Discovery of magnon self-interaction in a strongly driven antiferromagnet
Nonlinear dynamics govern a wide array of natural phenomena and are essential for understanding nonequilibrium behaviors in condensed matter systems. In magnetically ordered materials, magnons - the quanta of spin waves - exhibit intrinsic nonlinearities that are of great interest in fundamental research and practical applications. Despite progress in the nonlinear control of magnon modes in antiferromagnetic materials, the transition from perturbative to non-perturbative regimes of magnon cohe…

Calamus 25 The prairie-grass dividing
Whitman's celebration of simple men, of men from "inland America", of those who are unimpressed by Presidents and Governors. It's a romantic sentiment but in 2025 also feels a little naïve or condescending.
But as always I'm here for the gay stuff. Which starts explicitly enough
[I] Demand the most copious and close companionship of men
Well OK then! Me too. Maybe you could read that in a non-sexual way but then Whitman gets lusty
[I demand] Those with a never-quell'd audacity—those with sweet and lusty flesh, clear of taint, choice and chary of its love-power
My goodness, is that hot! At least to start, it's a shame he tames it seeking out men "chary of love-power". At least he recognizes their love power! I'll take the taint, thank you.

Controlling Effective Hamiltonians: Broadband Pulsed Dynamic Nuclear Polarization by Constrained Random Walk and Non-linear Optimization
We present constrained random walk (cRW) and figure of merit (FOM) based non-linear optimization procedures for systematic design and fundamental understanding of magnetic resonance experiments dressing bilinear and linear effective Hamiltonians to provide broadband polarization transfer. cRW can be used directly for fast random experiment design, or in combination with non-linear optimization or optimal control, leveraging the optimization of a FOM function for efficient control of linear and …

[In der sehr feinen Frankfurter Ausstellung über Japanese Women Photographers las ich keine Kurzbio einer Fotografin, in der nicht ein Weg ins Ausland zwecks (Teil-)Studiums vorkam. Es würde mich interessieren, ob das bei ihren männlichen Kollegen auch so ist. Meine Wahrnehmung ist, dass man als künstlerisch-wissenschaftliche Interessen verfolgende Japanerin im 20. Jh. praktisch ins Ausland musste, weil Barrieren in Japan zu hoch und Möglichkeiten zu wenige.]

Calamus 32 What think you...
A funny gotcha of a poem: Whitman starts by suggesting he is going to write about battleships, or cities, or "splendors". But then he switches gears:
two simple men I saw to-day ... parting the parting of dear friends
And then goes into fully romantic
The one to remain hung on the other's neck, and passionately kissed him,
While the one to depart, tightly prest the one to remain in his arms.
Hot, right? A passionate kiss, a tight embrace, never wanting to let go.
Again I am astonished that a poem this gay would be published in 1860. Or that generations of bloodless scholars would sputter and say "they were just pals".

Dynamic guessing for Hamiltonian Monte Carlo with embedded numerical root-finding

Dynamic guessing for Hamiltonian Monte Carlo with embedded numerical root-finding
Modern implementations of Hamiltonian Monte Carlo and related MCMC algorithms support sampling of probability functions that embed numerical root-finding algorithms, thereby allowing fitting of statistical models involving analytically intractable algebraic constraints. However the application of these models in practice is limited by the computational cost of computing large numbers of numerical solutions. We identify a key limitation of previous approaches to HMC with embedded root-finding, w…

Calamus 28 When I peruse the conquered fame of heroes
My surface reading is this is a celebration of the common man, perhaps soldiers, over the more famous generals and presidents. But this commentary encourages me to dig deeper.
First, to highlight the gay text...
the brotherhood of lovers ... Through youth, and through middle and old age, how unfaltering, how affectionate and faithful they were
Very homoromantic language! Male lovers who stay together through their whole lives, affectionate.
The last fillip here is Whitman's own stance: "pensive... filled with the bitterest envy". Whitman admires these lovers and envies them. That's a striking feeling to disclose!

Terahertz field-induced metastable magnetization near criticality in FePS3

Terahertz field-induced metastable magnetization near criticality in FePS3
Controlling the functional properties of quantum materials with light has emerged as a frontier of condensed-matter physics, leading to the discovery of various light-induced phases of matter, such as superconductivity, ferroelectricity, magnetism and charge density waves. However, in most cases, the photoinduced phases return to equilibrium on ultrafast timescales after the light is turned off, limiting their practical applications. Here we use intense terahertz pulses to induce a metastable m…

Calamus 31 What ship, puzzled at sea
Just when I'm beginning to think I have some facility reading Whitman I meet a head-scratcher like this. Taken literally this is a poem about Whitman offering to guide a boat at sea, or to offer military troops to a besieged city.
But presumably it's a metaphor. Whitman offering to guide and help those in need. It's a little strange?
Hard-pressed for a gay reading here but I'll focus on this:
Here, sailor! Here, ship! take aboard the most perfect pilot.
Here Whitman is offering himself to a sailor, naming himself the most perfect pilot. I could imagine that being a metaphor of sexual mentorship. But honestly that's a stretch.
