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.

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…

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…

What do y’all do with the Nintendo Switch when you get the Switch 2? Sell it? Put it in storage?
Switch 2 will presumably play most of the Switch 1 games but local multiplayer across generations will not work easily, I guess? Why would I keep it in any capacity?

Closed-form solutions for VIX derivatives in a Legendre empirical model
In this paper, we introduce a data-driven, single-parameter Markov diffusion model for the VIX. The volatility factor evolves in $(-1,1)$ with a uniform invariant distribution ensured by Legendre polynomials, mapped to the empirical distribution. We derive analytical series solutions for VIX futures and options using separation of variables to solve the Feynman-Kac PDE. Compared to the 3/2 model, our approach offers equal or superior accuracy and flexibility, providing an efficient, robust alte…
