Goodness-of-fit testing for the stationary density of a size-structured PDE
We consider two division models for structured cell populations, where cells can grow, age and divide. These models have been introduced in the literature under the denomination of `mitosis' and `adder' models. In the recent years, there has been an increasing interest in Biology to understand whether the cells divide equally or not, as this can be related to important mechanisms in cellular aging or recovery. We are therefore interested in testing the null hypothesis $H_0$ where the division o…

Calamus 17 Of him I love day and night
A disturbing poem about death, the death of a lover, the death of a city, the death of the poet. And Whitman's own dismissal of death, or at least of memorializing it.
Reading this as someone who grew up in the 80s, I can only read this in reflection on the AIDS crisis. Of my own community's deaths.
And I found that every place was a burial-place,
The houses full of life were equally full of death
The poem doesn't offer any solace in this reading. It is just a marker of death and being exposed to so much death that we are inured to it.

Homological Invariants of Left and Right Serial Path Algebras
We investigate the relationship between the delooping level (dell) and the finitistic dimension of left and right serial path algebras. These 2-syzygy finite algebras have finite delooping level, and it can be calculated with an easy and finite algorithm. When the algebra is right serial, its right finitistic dimension is equal to its left delooping level. When the algebra is left serial, the above equality only holds under certain conditions. We provide examples to demonstrate this and include…

Sonnet 111 - CXI
O! for my sake do you with Fortune chide,
The guilty goddess of my harmful deeds,
That did not better for my life provide
Than public means which public manners breeds.
Thence comes it that my name receives a brand,
And almost thence my nature is subdued
To what it works in, like the dyer's hand:
Pity me, then, and wish I were renewed;
Whilst, like a willing patient, I will drink
Potions of eisell 'gainst my…

Modelling Adjectival Modification Effects on Semantic Plausibility
While the task of assessing the plausibility of events such as ''news is relevant'' has been addressed by a growing body of work, less attention has been paid to capturing changes in plausibility as triggered by event modification. Understanding changes in plausibility is relevant for tasks such as dialogue generation, commonsense reasoning, and hallucination detection as it allows to correctly model, for example, ''gentle sarcasm'' as a sign of closeness rather than unkindness among friends [9…

PSA: 🥵 Idk who needs to hear this, but in a heatwave for the love of science use air conditioning. If you don’t have air conditioning, get a portable unit as soon as possible.
The climate is going to get hotter and heat can very easily kill you or a loved one or a pet; or cause permanent disability.
Heat is a lot more dangerous than cold temperatures; even if you’re “young and healthy”.
The climate is already fucked and has long reached a tipping point as far as humans go—our only bet is large-scale CO2 extraction.
Sacrificing your health “to save energy*” for an imaginary fight that we have already lost is stupid. It’s also one of those “individual responsibility” mindfucks—the culprits for pollution are industry maximizing profits and governments that are not acting.
Anyway, stay cool.
*note that AC uses overall a lot less energy than heating does

🌐 GÉANT sets a new benchmark for long-haul optical networking: 3,403 km of terrestrial transmission at 400G without transponders or regeneration!
This field trial, conducted in June on the GÉANT live production network using Cisco / Acacia 400G ULH QSFP-DD coherent pluggable optics, demonstrates the capabilities of new technologies to bridge extended distances without the need of traditional stand-alone DWDM transponders.

If you're not against the Trump administration and its full-blown destruction of science and democracy.. Then you are for it. So sad to see that this is apparently the path chosen by #DartmouthCollege, so easily contributing to the "divide and conquer" Trump strategy.

Tracers of the ionization fraction in dense and translucent molecular gas: II. Using mm observations to constrain ionization fraction across Orion B
The ionization fraction ($f_\mathrm{e}=n_\mathrm{e}/n_\mathrm{H}$) is a crucial parameter of interstellar gas, yet estimating it requires deep knowledge of molecular gas chemistry and observations of specific lines, such as those from isotopologs like HCO$^+$ and N$_2$H$^+$, which are detectable only in dense cores. Previous challenges in constraining $f_\mathrm{e}$ over large areas stemmed from the limitations of observational tracers and chemical models. Recent models have identified molecula…
