Self‐Similar Blowup for the Cubic Schrödinger Equation

open access: yesCommunications on Pure and Applied Mathematics, Volume 79, Issue 8, Page 1831-1918, August 2026.
ABSTRACT We give a rigorous proof for the existence of a finite‐energy, self‐similar solution to the focusing cubic Schrödinger equation in three spatial dimensions. The proof is computer‐assisted and relies on a fixed point argument that shows the existence of a solution in the vicinity of a numerically constructed approximation.

Validation of ShakeMaps Created From Global Navigation Satellite System (GNSS) Velocities

open access: yesEarthquake Spectra, Volume 42, Issue 3, August 2026.
Ground velocity observations generated through a time difference of Global Navigation Satellite Systems (GNSS) phase observables and orbits have been shown to be comparable to seismic recordings without clipping during intense ground motions. Computing GNSS velocities is also computationally scalable and increases the density of ground motion ...

Knocking Off the Street: The Subversive Writings of Hong Kong's Grassroots Kings

open access: yesCity &Society, Volume 38, Issue 2, August 2026.

Moving beyond celebratory collective memory narratives and easy analogies to graffiti, it frames their works as subversive urban practices that rework ...

Powerful representation of the poor? German welfare associations' narrative advocacy during COVID‐19

open access: yesPolicy Studies Journal, Volume 54, Issue 3, August 2026.
Abstract The COVID‐19 pandemic sparked unprecedented experimentation in the German social assistance system, leading to changes previously considered impracticable by policymakers. This included a sanctions moratorium, easier access to benefits, and temporary cash transfers, all of which were advocated by welfare associations—key organized interests ...

Who Holds the Power? Gendered Experiences of Involuntary Singlehood in the Age of Online Dating*

open access: yesSociological Inquiry, Volume 96, Issue 3, August 2026.
Although singlehood is a desired lifestyle for an increasing number of heterosexual women and men, many are involuntarily single, struggling to find a partner. Meanwhile, popular debates about dating are sharply polarized along gendered lines. While “incels” see themselves as victims on a dating market ruled by women, relatively mainstreamed feminist ...
