We just had so much fun at home reading the most recent and some older german"#Jugendwort des Jahres" (words of the youth) - sorry, article in german:

Dealogic: 51 US tech IPOs raised $16.8B in 2025, driven by AI and crypto, above the past three-year average but far below 2021's 127 IPOs raising $74.4B (Valida Pau/The Information)

AI and Crypto Companies Dominated IPO Winners in 2025
The drought in initial public offerings ended this year, led by big winners in AI and crypto, but gains were rare for companies outside those industries. Bankers expect those trends to hold in 2026. Booms in AI and crypto delivered two of the biggest winners of the year: data center developer ...

Weekend #Plankton Factoid 🦠🦐
Since 2011, millions of tons of a brown algae called Sargassum has washed onto beaches in the Caribbean. The rotting seaweed releases toxic hydrogen sulfide, smelling of rotten eggs, impacting tourism and shore access. It was initially thought Saharan iron dust was the cause, but new #science

Modified Loss of Momentum Gradient Descent: Fine-Grained Analysis
We analyze gradient descent with Polyak heavy-ball momentum (HB) whose fixed momentum parameter $β\in (0, 1)$ provides exponential decay of memory. Building on Kovachki and Stuart (2021), we prove that on an exponentially attractive invariant manifold the algorithm is exactly plain gradient descent with a modified loss, provided that the step size $h$ is small enough. Although the modified loss does not admit a closed-form expression, we describe it with arbitrary precision and prove global (f…

Impact of Pulsar SAX J1748.9-2021 Observations on $f(\mathcal{Q}, \mathbb{T})$ Gravity
The main objective of this study is to investigate the viability and stability of a pulsar filled with anisotropic matter in $f(\mathcal{Q}, \mathbb{T})$ gravity, where $\mathcal{Q}$ represents non-metricity and $\mathbb{T}$ is the trace of the energy-momentum tensor. In this context, we employ non-singular solution and a particular model of this gravity. We use junction conditions to evaluate unknown constants in the metric coefficients. Observations from the pulsar SAX J1748.9-2021 star are e…

Moment-SOS hierarchies for arrow-type polynomial matrix inequalities with applications to structural optimization
The Arrow Decomposition (AD) technique, initially introduced in [Mathematical Programming 190(1-2) (2021), pp 105-134], demonstrated superior scalability over the classical chordal decomposition in the context of Linear Matrix Inequalities (LMIs) if the matrix in question satisfied suitable assumptions. The primary objective of this paper is to extend the AD method to address Polynomial Optimization Problems (POPs) involving large-scale Polynomial Matrix Inequalities (PMIs), with the solution f…

Emergent Hierarchy in Localized States of Organic Quantum Chains
Organic Quantum Chains (OQCs) represent a newly synthesized class of carbon-based nanostructures whose quasi-one-dimensional nature gives rise to unconventional electronic and transport phenomena. Here we investigate the electronic and transport properties of recently synthesized OQCs [Nature Communications, 12, 5895 (2021)]. Structural stability was first assessed through molecular dynamics relaxation combined with density functional theory (DFT). The optimized coordinates are then used in a t…

A note on Wang's conjecture for harmonic functions with nonlinear boundary condition
We obtain some Liouville type theorems for positive harmonic functions on compact Riemannian manifolds with nonnegative Ricci curvature and strictly convex boundary and partially verifies Wang's conjecture (J. Geom. Anal. 31 (2021)). For the specific manifold $\mathbb{B}^n$, we present a new proof of this conjecture, which has been resolved by Gu-Li (Math. Ann. 391 (2025)). Our proof is based on a general principle of applying the P-function method to such uniqueness results. As a further app…

Good Morning #Canada
I've been a bachelor since Thursday as my wife is in Toronto helping my daughter with her latest chemo session. She's back late Monday when life, for me, returns to normal. According to #StatsCan, being married at our age (late 60s) is the most prevalent relationship. But Canadians in younger age brackets are more likely these days to be living common-law and getting married later in life, if at all. Canada has one of the highest rates of common-law relationships worldwide and the highest in the G7. Between 1981 and 2021, common-law couples increased 447% while the number of married couples grew by only 26%. Common-law unions are most prevalent in Nunavut (52%), Quebec (43%), and the Northwest Territories (36%). It's no surprise that more than half of Canadians believe that marriage is not necessary, and even less surprising that this opinion is stronger with young men versus young women.
