Complete Intersection Fibers in F-Theory [PDF]

open access: yes, 2015
Global F-theory compactifications whose fibers are realized as complete intersections form a richer set of models than just hypersurfaces. The detailed study of the physics associated with such geometries depends crucially on being able to put the ...

Measuring scientific classroom discourse: The DiISC Version 2.0's validity and use in observing secondary science lessons

open access: yesSchool Science and Mathematics, EarlyView.
Abstract To continue to support long‐term, ongoing science curriculum and instruction reform efforts in the United States, there is a significant need to be able to reliably measure teachers’ discourse‐rich, inquiry‐based instruction. In this external validation study, we present the Discourse in Inquiry Science Classrooms Version 2.0 (DiISC 2.0) as a ...

$B\to \phi \pi$ and $B^0 \to \phi\phi$ in the Standard Model and new bounds on R parity violation

open access: yes, 2002
We study the pure penguin decays $B \to \phi\pi$ and $B^0 \to \phi\phi$. Using QCD factorization, we find ${\cal B}(B^\pm \to\phi\pi^{\pm} )=2.0^{+0.3}_{-0.1}\times 10^{-8}$. For the pure penguin annihilation process $B^0 \to \phi\phi$, analyzed here for

Can the EU Move ‘Beyond GDP’?

open access: yesJCMS: Journal of Common Market Studies, Volume 64, Issue 2, Page 491-510, March 2026.
Abstract Since 2007, the European Union has devoted significant time and energy to the production and dissemination of new statistics designed to monitor social and environmental trends of various types. These initiatives have often been presented as part of a broader ‘beyond GDP agenda’, which challenges the centrality of economic growth, as measured ...

Gluon production on two centers and the effective action approach

open access: yes, 2011
Application of the effective action formalism is studied for processes in which the reggeons may split. It is shown that the gluon production on two centers is described by the contribution of the Reggeon-to-two-Reggeons-plus-Particle vertex supplemented

Jacobian Nullwerte, Periods and Symmetric Equations for Hyperelliptic Curves [PDF]

open access: yes, 2006
We propose a solution to the hyperelliptic Schottky problem, based on the use of Jacobian Nullwerte and symmetric models for hyperelliptic curves.

Peptide Sequencing With Single Acid Resolution Using a Sub‐Nanometer Diameter Pore

open access: yesAdvanced Functional Materials, Volume 36, Issue 15, 19 February 2026.
To sequence a single molecule of Aβ1−42–sodium dodecyl sulfate (SDS), the aggregate is forced through a sub‐nanopore 0.4 nm in diameter spanning a 4.0 nm thick membrane. The figure is a visual molecular dynamics (VMD) snapshot depicting the translocation of Aβ1−42–SDS through the pore; only the peptide, the SDS, the Na+ (yellow/green) and Cl− (cyan ...

Curvularia infection presenting as recurrent conjunctival erosion overlying a scleral-fixated intraocular lens suture

open access: yesAmerican Journal of Ophthalmology Case Reports, 2022
Purpose: To describe a case of an indolent, chronic Curvularia infection after a ruptured globe injury from an intraocular metallic foreign body in a 38-year old male. Following globe repair and vitrectomy, the patient underwent a sutured scleral-fixated
