Back in 1964, microbiologist Tom Brock received a grant from the National Science Foundation to study how life works at high temperatures,
a question that took him to Yellowstone’s hot springs in search of extremophiles.
There, he and his student discovered a bacteria they called Thermus aquaticus,
which had enzymes that could work at incredibly high temperatures.
Two decades later, this discovery paved the way for the development of a technique called polymerase ch…

What It Would Mean To Lose The National Science Foundation
In a companion piece to our previous article on the NIH, we discuss the importance of the National Science Foundation (NSF) and how the agency is currently being affected by political interference.

Models for cyclic infinity operads
We construct model structures on cyclic dendroidal sets and cyclic dendroidal spaces for cyclic quasi-operads and complete cyclic dendroidal Segal spaces, respectively. We show these models are Quillen equivalent to the model structure for simplicial cyclic operads. This answers in the affirmative a question of the second author and Drummond-Cole concerning model structures for cyclic $\infty$-operads. We infer similar statements for planar cyclic $\infty$-operads, providing the model-categoric…

Spherically Symmetric Potentials in Quadratic $f(R)$ Gravity
We study the gravitational potential arising from static, spherically symmetric sources in a modified gravity theory described by a quadratic $f(R)$ model. The linearized field equations lead to a fourth-order differential equation, whose solution includes Newtonian and Yukawa-like terms. Imposing regularity at the origin and asymptotic flatness fixes all integration constants, making the potential fully determined by the mass distribution. We analyze classical profiles such as Plummer, Hernqui…

On polynomial inequalities for cone-volumes of polytopes
Motivated by the discrete logarithmic Minkowski problem we study for a given matrix $U\in\mathbb{R}^{n\times m}$ its cone-volume set $C_{\tt cv}(U)$ consisting of all the cone-volume vectors of polytopes $P(U,b)=\{ x\in\mathbb{R}^n : U^\intercal x\leq b\}$, $b\in\mathbb{R}^n_{\geq 0}$. We will show that $C_{\tt cv}(U)$ is a path-connected semialgebraic set which extends former results in the planar case or for particular polytopes. Moreover, we define a subspace concentration polytope $P_{\tt s…

Just a little PSA to any trail bikers in the UK who find the https://stegra.io app interesting...
Many of the byways that they are highlighting on the map are actually illegal to ride - they are closed with a TRO. It seems Stegra didn’t take this into account at all 🤦‍♀️

Inverse method for determining general molecular weight distribution from polymer rheology
Determination of polymer molecular weight distribution (MWD) from rheological measurements is desirable due to the ease and low cost of rheometry compared to other methods such as gel permeation chromatography. However, relating MWD to rheology requires the inversion of rheological models, for which there is no analytic solution. Prior approaches assume a functional form for the MWD (such as a lognormal or generalized exponential distribution), minimizing the error with respect to the functiona…
