Switching 50km/h speed limits to 30km/h would protect cyclists while barely affecting commutes, research finds
One expert says a cyclist hit by a car travelling 50km/h has about a one-in-10 chance of surviving, while at 30km/h it is a nine-in-10 chance

Embedding finitely generated free-by-cyclic groups in {finitely generated free}-by-cyclic groups
We refine Feighn--Handel's results on subgroups of mapping tori of free groups to the special case of free-by-cyclic groups. We use these refinements to show that any finitely generated free-by-cyclic group embeds in a {finitely generated free}-by-cyclic group. When the free-by-cyclic group is hyperbolic, it embeds in a hyperbolic {finitely generated free}-by-cyclic group as a quasi-convex subgroup. Combined with a result of Hagen--Wise, this implies that all hyperbolic free-by-cyclic groups ar…

"Every morning, a spider rebuilt its web on my car mirror, only for the wind to destroy it again. Watching that tiny creature taught me something about toxic cycles, misplaced resilience, and the quiet courage it takes to stop rebuilding in the wrong place."
"True resilience isn't about stubbornly withstanding the storm; it's about having the wisdom to find a new foundation."
This piece of writing hits like a gut punch.

What a Spider Taught Me About Resilience and Letting Go
Every morning, a spider rebuilt its web on my car mirror, only for the wind to destroy it again. Watching that tiny creature taught me something about toxic cycles, misplaced resilience, and the quiet courage it takes to stop rebuilding in the wrong place.

From Autoencoders to CycleGAN: Robust Unpaired Face Manipulation via Adversarial Learning
Human face synthesis and manipulation are increasingly important in entertainment and AI, with a growing demand for highly realistic, identity-preserving images even when only unpaired, unaligned datasets are available. We study unpaired face manipulation via adversarial learning, moving from autoencoder baselines to a robust, guided CycleGAN framework. While autoencoders capture coarse identity, they often miss fine details. Our approach integrates spectral normalization for stable training, i…

Either too little or too much: Report finds world's water cycles are getting more erratic
The water cycle has become increasingly erratic and extreme, swinging between deluge and drought, according to a new report from the World Meteorological Organization (WMO). It highlights the cascading impacts of too much or too little water on economies and society.

An elementary derivation of 3-cycles for a quadratic map
We present an elementary derivation of the period-three cycles for the real quadratic map $x\mapsto x^2+c$, a fundamental model in one-dimensional discrete dynamics. Using symmetric polynomials, we obtain a complete algebraic characterization of 3-cycles and determine explicit conditions for their existence and stability, without reliance on computer algebra. Through conjugacy with the logistic map, we recover the classical threshold values of the logistic parameter corresponding to the emergen…

Algebraic cycles of some Fano varieties with Hodge structure of level one
We study Chow groups and étale motivic cohomology groups of smooth complete intersections with Hodge structures of level one, classified by Deligne and Rapoport, with particular attention to fivefolds. We extend these results to an étale motivic context and recover an analogous finite-dimensionality in the sense of Kimura. We further analyse algebraic cycles on other smooth Fano manifolds with Hodge structures of level one and, as an application, we prove the integral Hodge conjecture for smo…

Cyclic and alternating $U$-statistics
We define cyclic $U$-statistics as a variant of $U$-statistics based on variables $X_1,\dots,X_n$ that are assumed to be cyclically ordered. We also define alternating $U$-statistics where in the definition terms are summed with alternating sings (in three different ways). Only $U$-statistics of order 2 are considered. The definitions are inspired by special cases studied by Chebikin (2008) and Even-Zohar (2017) for random permutations. We show limit theorems similar to well-known results for…
