The anomalous threshold, confinement, and an essential singularity in the heavy-light form factor [PDF]

open access: yes, 1997
The analytic behavior of the heavy-light meson form factor is investigated using several relativistic examples including unconfined, weakly confined, and strongly confined mesons. It is observed that confinement erases the anomalous threshold singularity

Assessing Photovoltaic Recycling Capacities and Policy Gaps in the European Union

open access: yesAdvanced Energy and Sustainability Research, EarlyView.
This study maps photovoltaic recycling capacity in the EU and key global regions, highlighting gaps between growing waste volumes and available infrastructure. It combines survey insights and policy analysis to identify recycling bottlenecks and offers recommendations to boost circularity in the solar sector.

Preprint Pointers From a Long COVID Scoping Review: Considerations for Source Selection and Searching

open access: yesJournal of the Canadian Health Libraries Association
This paper describes the search approach for preprints for a post–COVID-19 condition (i.e., long COVID) scoping review, including source selection, search strategy development, challenges, and insights throughout a project life cycle. With the growth of

Cell Segmentation Beyond 2D—A Review of the State‐of‐the‐Art

open access: yesAdvanced Intelligent Discovery, EarlyView.
Cell segmentation underpins many biological image analysis tasks, yet most deep learning methods remain limited to 2D despite the inherently 3D nature of cellular processes. This review surveys segmentation approaches beyond 2D, comparing 2.5D and fully 3D methods, analyzing 31 models and 32 volumetric datasets, and introducing a unified reference ...

Using an expert survey and user feedback to construct PRECHECK: A checklist to evaluate preprints on COVID-19 and beyond [version 3; peer review: 1 approved, 2 approved with reservations, 1 not approved]

open access: yesF1000Research
Background The quality of COVID-19 preprints should be considered with great care, as their contents can influence public policy. Surprisingly little has been done to calibrate the public’s evaluation of preprints and their contents. The PRECHECK project

Universal behaviour of the SU(2) running coupling constant in the continuum limit

open access: yes, 1994
We present data from the ALPHA Collaboration about lattice calculation of SU(2) pure--gauge running coupling constant, obtained with two different definitions of the coupling itself, which show universality of the continuum limit and clarify the ...

Large Language Model‐Based Chatbots in Higher Education

open access: yesAdvanced Intelligent Systems, Volume 7, Issue 3, March 2025.
The use of large language models (LLMs) in higher education can facilitate personalized learning experiences, advance asynchronized learning, and support instructors, students, and researchers across diverse fields. The development of regulations and guidelines that address ethical and legal issues is essential to ensure safe and responsible adaptation

Threshold amplitudes in field theories and integrable systems

open access: yes, 1995
We discuss the threshold tree amplitudes in diverse nonintegrable quantum field theories in the framework of integrability. The amplitudes are related to some Baker functions defined on the auxiliary spectral curves and the nullification phenomena are ...

Partially or fully (“silently”) withdrawn or retracted Center for Open Science preprints

open access: yesCentral Asian Journal of Medical Hypotheses and Ethics
In academia, one of the publishing models available to authors are preprints, which are non-peer-reviewed documents that typically serve as a prelude to submissions to peer-reviewed journals.

Global Range Estimates for Maximal Oscillatory Integrals with Radial Testfunctions [PDF]

open access: yes, 2011
We consider the maximal function of oscillatory integrals and prove a global estimate for radial test functions which is almost sharp with respect to the Sobolev regularity.Comment: Preprints in Mathematical Sciences 2011:1 ISSN 1403-9338, LUNFMA-5068 ...
