On fixed points of pseudo-Anosov maps

We give a formula to estimate the number of fixed points of a pseudo-Anosov homeomorphism of a surface. When the homeomorphism satisfies a mild property called strong irreducibility , the log of the number of fixed points is coarsely equal to the Teichmüller translation length. W...

The Neutral Hydrogen Gas Content of Star-forming and Quiescent S0 Galaxies

Abstract Lenticular (or S0) galaxies that remain actively star-forming (SFS0s) are a unique transition population among galaxies. We investigated the HI (21cm) neutral hydrogen content of a sample of lenticular galaxies identified from within the Mapping Nearby Galaxies at Apache...

Islamic China: An Asian History

Islamic China: An Asian History is an extraordinary book that aims to render China’s Muslims “ordinary.” It’s a book about books and those who compose them, print them, carry them over steep mounta...

When Threat Affirms: Expanding Self-Affirmation Theory Through the Asian-White Multiracial Experience

While existing literature on self-affirmation has advanced our understanding of its protective function when self-integrity is threatened, relatively little attention has been given to the nature and role of the threat itself. To address this gap, the present collaborative autoet...

Creating NewAccess Points for Strategic SynthaseEngineering: Ethane Thioester Analogs as Truncated Coenzyme A BuildingBlocks Unlock Expanded Acyl Carrier Protein Loading Capabilities

Abstract Strategic engineering of natural product biosynthetic pathways through the incorporation of alternative, tunable carbon-based building blocks represents a promising approach for accessing medicinally relevant molecules. However, efforts toward this goal have been hindere...

Learning Along the Way: Novice Teachers’ Reflections on Developing Critical Race Praxis in Urban Schools

This qualitative study investigates how former teacher candidates, trained in critical race inquiry as undergraduates, conceptualize and enact race consciousness and racial literacy in their early years of in-service teaching. Grounded in Critical Race Praxis and Racial Literacy,...
