DIFNet: SAR RFI suppression based on domain invariant features
Synthetic aperture radar is a high-resolution two-dimensional imaging radar, however, during the imaging process, SAR is susceptible to intentional and unintentional interference, with radio frequency interference (RFI) being the most common type, leading to a severe degradation in image quality. Although inpainting networks have achieved excellent results, their generalization is unclear, and whether they still work effectively in cross-sensor experiments needs further verification. Through ti…

Numerical simulation of the Gross-Pitaevskii equation via vortex tracking
This paper deals with the numerical simulation of the Gross-Pitaevskii (GP) equation, for which a well-known feature is the appearance of quantized vortices with core size of the order of a small parameter $\varepsilon$. Without a magnetic field and with suitable initial conditions, these vortices interact, in the singular limit $\varepsilon\to0$, through an explicit Hamiltonian dynamics. Using this analytical framework, we develop and analyze a numerical strategy based on the reduced-order Ham…

I once had a conversation with a professor of process philosophy about how we can be open to the prospect that there's only one Act, and that everything is that Act a certain way. And, given that adverbs can modify verbs and other adverbs, everything can be appreciated as an expression of that Act ... lovingly.
My toddler daughter was sitting on my knee during the conversation, and she summed up our philosophical musings this way:
"Hunky-dory is how everything is make.&q…

I figured out how responsive images work. Yay! (I know kung-fu)
- Prescriptive (let the browser figure it out) use `img`, `srcset`, and `sizes`
- Descriptive (do what I say) use the `picture` tag.
Descriptive is more verbose but predictable, whereas prescriptive is “Browser take the wheel!”
Thanks to @… for the docs link.

Was diese kleine Splitter-Blockadepartei aus Deutschland anrichtet, ist schon beeindruckend. Permanent neue Meldungen, welche zukunftsfähigen Ideen sie wieder blockiert hat. Egal ob Menschenrechte oder ein bewohnbarer Planet: Blockieren als Grundsatz!
Und die anderen beiden Parteien unserer Koalition schauen Tag für Tag zu, während sich ihr kleinster Koalitions"partner" immer weiter ins politische Abseits schießt.

The Prime Geodesic Theorem and Bounds for Character Sums
We establish the prime geodesic theorem for the modular surface with exponent $\frac{113}{164}+\varepsilon$, improving upon the long-standing exponent $\frac{25}{36}+\varepsilon$ of Soundararajan-Young (2013). Our argument goes through a well-trodden trail via the automorphic machinery, and refines the methods of Iwaniec (1984) and Cai (2002) to a maximum extent. Furthermore, we apply Burgess bounds for character sums in short intervals, combined with hybrid Weyl-strength subconvex bounds for q…

Khintchine-type double recurrence in abelian groups
We prove a Khintchine-type recurrence theorem for pairs of endomorphisms of a countable discrete abelian group. As a special case of the main result, if $Γ$ is a countable discrete abelian group, $φ, ψ\in End(Γ)$, and $ψ- φ$ is an injective endomorphism with finite index image, then for any ergodic measure-preserving $Γ$-system $\left( X, \mathcal{X}, μ, (T_g)_{g \in Γ} \right)$, any measurable set $A \in \mathcal{X}$, and any $\varepsilon > 0$, the set of $g \in Γ$ for which $$μ\lef…
