Spatial and Temporal Evaluations of the Liquid Argon Purity in ProtoDUNE-SP
Liquid argon time projection chambers (LArTPCs) rely on highly pure argon to ensure that ionization electrons produced by charged particles reach readout arrays. ProtoDUNE Single-Phase (ProtoDUNE-SP) was an approximately 700-ton liquid argon detector intended to prototype the Deep Underground Neutrino Experiment (DUNE) Far Detector Horizontal Drift module. It contains two drift volumes bisected by the cathode plane assembly, which is biased to create an almost uniform electric field in both vol…

In a recent study, we tested pine wood chips and biochar – a form or charcoal made from heating rice husks in a limited oxygen chamber, a process known as pyrolysis – and found they could remove approximately 90% of tire wear …

One of the biggest microplastic pollution sources isn’t straws or grocery bags – it’s your tires
Rain storms wash those tire shards into streams and ultimately into lakes and oceans. That’s bad news for fish and other aquatic life.

A conjecture on the tensor ideal for an elementary p-group generated by the restriction of a Steinberg module
In previous work (Coulembier--Flake 2024), the authors conjectured that the tensor product of an arbitrary finite-dimensional modular representation of an elementary abelian $p$-group with the biggest non-projective restricted Steinberg $SL_2$-module is a restricted tilting module. We showed that the validity of the conjecture would have interesting implications in the theory of tensor categories in positive characteristic, in particular, with respect to the classification of incompressible sym…

NLO QCD effects on angular observables in $e^-p \to e^-(ν_e)Hj$ in presence of non-standard $HVV$ couplings
The single Higgs production in neutral-current (NC) and charged-current (CC) processes at an electron-proton ($ep$) collider is a useful channel to probe new physics effects in the Higgs coupling to vector boson ($HVV$). In this context, observables sensitive to non-standard couplings previously studied at leading order require improved theoretical precision through the inclusion of radiative corrections. In this work, we present a fully differential Higgs plus one jet production at next-to-lea…

pycnet-audio: A Python package to support bioacoustics data processing
Passive acoustic monitoring is an emerging approach in wildlife research that leverages recent improvements in purpose-made automated recording units (ARUs). The general approach is to deploy ARUs in the field to record on a programmed schedule for extended periods (weeks or months), after which the audio data are retrieved. These data must then be processed, typically either by measuring or analyzing characteristics of the audio itself (e.g. calculating acoustic indices), or by searching for s…

Fano schemes of sub-maximal elementary symmetric functions
Denote by $E_r$ the $r^{th}$ elementary symmetric polynomial in $\dim V$ variables for a vector space $V$ over an infinite field $\Bbbk$. We describe the rational points on the Fano scheme $F_{d-1}(Z(E_{\dim V-1}))$ of projective $(d-1)$-spaces contained in the zero locus of $E_{\dim V-1}$. Isolated points exist precisely for $\dim V=2d$, in which case they are in bijection with the $1\cdot 3\cdots (2d-1)$ pairings on a $2d$-element set. This, in particular, confirming a conjecture of Ambartsou…

I've never written a novel or any other intensely-plotted work of fiction, but anyone who has read or watched it played a lot of stories can probably also recognize that some authors just aren't good at endings. They're great at setting things in motion, at keeping the twists and turns coming, at the soap opera style of drama. But they just don't have the craft necessary to tie things together into a satisfying conclusion. I imagine it's much harder than the process of getting things going out keeping them moving, since you both have to wind down all the various threads you've spun up and balance satisfaction with believability.
I just finished Girl Gone Viral by Arvin Ahmadi, and it has a bad ending. The beginning is fine, the middle has plenty of drama to keep you wanting to see what happens, but the ending is murky, unsatisfying, and manages neither veracity nor satisfaction (even discounting the biggest next step that might reasonably have been left there to make room for a sequel).
Given the other issues with the book, from poor politics, to inauthentic characters, to a techno-optimism that feels as bitter in this moment as it is far from the mark in its predictions, I can't recommended it, despite having read through to the end.

Biquandle cocycle condition for invariants of immersed surface-links in the four-space

Biquandle cocycle condition for invariants of immersed surface-links in the four-space
We consider a biquandle-cohomological framework for invariants of oriented immersed surface-links in the four-space. After reviewing projections and Roseman moves for immersed surfaces, we prove that the move types (a,b,c,e,f,g,h) form a minimal generating set, showing in particular that the singular move (h) is independent of the embedded-case set (a,b,c,e,f,g). We extend biquandle colorings to broken surface diagrams with singular points and establish that coloring sets are in bijection for d…

Design of an all-facet illuminator for high NA EUV lithography exposure tool based on deep reinforcement learning
Using the illuminator for high numerical aperture (NA) extreme ultraviolet (EUV) exposure tool in EUV lithography can lead to support volume production of sub-2 nm logic nodes and leading-edge DRAM nodes. However, the typical design method of the illuminator has issues with the transmission owing to the limitation of optical structure that cannot further reduce process parameter k1, and uniformity due to the restriction of matching method that can only consider one factor affecting uniformity. …
