DACN: Dual-Attention Convolutional Network for Hyperspectral Image Super-Resolution
2D convolutional neural networks (CNNs) have attracted significant attention for hyperspectral image super-resolution tasks. However, a key limitation is their reliance on local neighborhoods, which leads to a lack of global contextual understanding. Moreover, band correlation and data scarcity continue to limit their performance. To mitigate these issues, we introduce DACN, a dual-attention convolutional network for hyperspectral image super-resolution. Specifically, the model first employs au…

Quick tip for those with young kids who want them to learn how to use a watch with an analogue (dial) style interface.
While the likes of Flik Flak make nice kids watches, they are a little on the pricy side.
Potentially better IMHO however are these kids field/pilot style watches from AliExpress. They cost basically nothing [<$5🇺🇸] and the hour hand points to an inner ring of numbered hours, while the minute hand points to an outer ring of numbered minutes. So simple!

Some thoughts from my self-reflection today. Maybe this helps someone.
I had to deal with a bunch of broken things today. Normally that greatly bothers me, but these were things I broke, and I broke them long ago. I have a lot of anger due to the circumstances around why I was never able to fix them. But that's not helpful. I could spend my hours in rage, or I could keep in mind that I can't undo the reasons for my anger. I can work towards fixing them, or documenting the…

What Monads Can and Cannot Do with a Few Extra Pages
The delay monad provides a way to introduce general recursion in type theory. To write programs that use a wide range of computational effects directly in type theory, we need to combine the delay monad with the monads of these effects. Here we present a first systematic study of such combinations. We study both the coinductive delay monad and its guarded recursive cousin, giving concrete examples of combining these with well-known computational effects. We also provide general theorems stati…

Delay Update in determinant quantum Monte Carlo
Determinant quantum Monte Carlo (DQMC) is a widely used unbiased numerical method for simulating strongly correlated electron systems. However, the update process in DQMC is often a bottleneck for its efficiency. To address this issue, we propose a generalized delay update scheme that can handle both onsite and extended interactions. Our delay update scheme can be implemented in both zero-temperature and finite-temperature versions of DQMC. We apply the delay update scheme to various strongly c…

Constraints on the progenitor models of fast radio bursts from population synthesis with the first CHIME/FRB catalog
Fast radio bursts (FRBs) are enigmatic extragalactic radio transients with unknown origins. We performed comprehensive Monte Carlo simulations based on the first CHIME/FRB catalog to test whether the FRB population tracks the cosmic star formation history directly or requires a delay. By fully considering CHIME's complex selection effects and beam response, we find that the hypothesis that the FRB population tracks the SFH is not ruled out by the current data, although a small delay is preferre…

Degree functions of graded families of ideals
We express multiplicities and degree functions of graded families of $\mathfrak{m}_R$-primary ideals in an excellent normal local ring $(R,\mathfrak{m}_R)$ as limits of intersection products. Moreover, in dimension 2, we show more refined results for divisorial filtrations. Finally, also in dimension 2, we give an example of a non-Noetherian divisorial filtration $\{I_n\}_{n\geqslant 0}$ of $\mathfrak{m}_R$-primary ideals such that the union of all the sets of Rees valuations of all the $I_n$ i…

Optical lever for broadband detection of fluid interface fluctuations
We exploit the optical lever principle to detect minute fluctuations of a liquid-air interface. Waves propagating on the interface deflect a specularly reflected laser beam, inducing angular deviations captured by a dual-element photodiode. We realise this principle in a compact set-up including a temperature-controlled fluid sample. Deflection angle fluctuations span five orders of magnitude in frequency, enabling detection of both low-frequency eigenmodes and high-frequency capillary waves dr…
