Shape-Wilf-equivalences for vincular patterns
Advances in Applied Mathematics, 2013 We extend the notion of shape-Wilf-equivalence to vincular patterns (also known as "generalized patterns" or "dashed patterns"). First we introduce a stronger equivalence on patterns which we call filling-shape-Wilf-equivalence. When vincular patterns $ $ and $ $ are filling-shape-Wilf-equivalent, we prove that the direct sum $ \oplus $ is filling ...

The stepwise rise of angiosperm‐dominated terrestrial ecosystems
Biological Reviews, Volume 100, Issue 5, Page 2131-2149, October 2025.ABSTRACT Angiosperms are the most diverse and abundant plant taxon today and dominate the majority of Earth's terrestrial ecosystems. They underwent rapid divergence and biogeographic expansion from the early to the middle Cretaceous. Yet, transformative ecosystem change brought about by the increased ecological dominance of angiosperms unfolded ...

Building the walls of international trade after war: Can dispute resolution mechanisms (DRMs) help?
Economic Inquiry, Volume 63, Issue 4, Page 1147-1169, October 2025.Abstract This paper explores how international trade recovers after war, emphasizing the role of dispute resolution mechanisms (DRMs). Wars typically prolong negative trade impacts due to heightened tensions, but DRMs—such as General Agreement on Tariffs and Trade/World Trade Organization and diplomatic exchanges—can reduce these tensions, lower policy

Journal of Biogeography, Volume 52, Issue 9, September 2025.ABSTRACT Savannas and rainforests co‐occur as mosaics across large areas of the tropics. These mosaics are dynamic, with savanna and rainforest switching in relatively short time scales, largely through the effects of fire. Most research to date addresses such biome switching through the lens of vegetation, with little attention given to faunal ...

Ecology and Evolution, Volume 15, Issue 7, July 2025.This research involved the sequencing and analysis of chloroplast genomes from nine species across four genera of the Solanaceae family, specifically two species of Archiphysalis, five species of Physaliastrum, and the taxa Tuberowithania pengiana and Tubocapsicum anomalum.

Fertility, Strong Fertility, and Postorder Wilf Equivalence
, 2019 We introduce "fertility Wilf equivalence," "strong fertility Wilf equivalence," and "postorder Wilf equivalence," three variants of Wilf equivalence for permutation classes that formalize some phenomena that have appeared in the study of West's stack-sorting map. We introduce "sliding operators" and show that they induce useful bijections among sets of

Lead or Follow? Participation Decisions in Collective Development Initiatives
Economics &Politics, Volume 37, Issue 2, Page 811-825, July 2025.ABSTRACT When and how do donors cooperate? While a growing literature emphasizes the importance of donor coordination for aid effectiveness, little is known about when and why donors join forces to advance common causes. We leverage the proliferation of special‐purpose trust funds at multilateral organizations to cast light on this issue. We argue that

European Journal of Neuroscience, Volume 62, Issue 1, July 2025.This study examined auditory novelty processing during dexmedetomidine anesthesia and during daytime sleep. Intracranial recordings were obtained in neurosurgical epilepsy patients. In both conditions, loss of consciousness was associated with confinement of local (short‐term) novelty responses to the auditory cortex and was preceded by cessation of ...
