Journal of High Energy PhysicsWe construct new half-BPS line defects in 3d N = 2 $$ \mathcal{N}=2 $$ supersymmetric quiver gauge theories whose Higgs branches are complete flag manifolds X = Fl(n). Upon circle compactification, the bulk theory flows to a non-linear sigma model (NLSM)

The special Schubert calculus is real
, 1998 We show that the Schubert calculus of enumerative geometry is real, for special Schubert conditions. That is, for any such enumerative problem, there exist real conditions for which all the a priori complex solutions are real.Comment: 5 ...

A retrospective on the 2025 Atlantic hurricane season
Weather, EarlyView.The 2025 Atlantic hurricane season was intermittent, with extended quiet periods separated by three clusters of activity. The broad‐scale conditions were often unfavourable for cyclogenesis and common drivers of activity such as La Niña were weak, but well above‐average sea temperatures still supported intense storms.

Marine Anoxia and Ocean Acidification During the End‐Permian Extinction
Geophysical Monograph Series, Page 325-340., 2021 Exploring the links between Large Igneous Provinces and dramatic environmental impact
An emerging consensus suggests that Large Igneous Provinces (LIPs) and Silicic LIPs (SLIPs) are a significant driver of dramatic global environmental and biological changes, including mass extinctions.

Journal of Algebra and Its ApplicationsIn this paper, we initiate the study of constant-dimension subspace codes restricted to Schubert varieties, which we call Schubert subspace codes. These codes have a very natural geometric description, as objects that we name intersecting sets with respect to a fixed subspace.

Phenology of migrating game birds in Italy based on citizen science data
Wildlife Biology, EarlyView.Studying the timing of the seasonal movements of migratory birds, known as migration phenology, is crucial for managing and conserving migratory bird populations. This is particularly important for migratory game bird populations in Europe because, according to the EU, migratory birds should not be hunted during their breeding season or during return ...

Caution Ahead: Numerical Reasoning and Look‐Ahead Bias in AI Models
Journal of Accounting Research, EarlyView.ABSTRACT Recent work within accounting and finance has highlighted that modern AI systems exhibit superhuman performance on a variety of foundational activities within these fields. However, the literature often does not provide economic rationale for why AI models seem to outperform, largely because these models are a black box.

Farmers' Beliefs About Climate Action: Evidence From an Information Experiment
Journal of Agricultural Economics, EarlyView.ABSTRACT Farmers' adoption of climate change mitigation practices is crucial for reducing greenhouse gas (GHG) emissions from food production. One major source of these emissions is chemical fertilizer application. Introducing clover into grassland can mitigate emissions by reducing the need for chemical fertilizers.
