Modular Calabi-Yau fourfolds and connections to M-theory fluxes

Journal of High Energy Physics
In this work, we study the local zeta functions of Calabi-Yau fourfolds. This is done by developing arithmetic deformation techniques to compute the factor of the zeta function that is attributed to the horizontal four-form cohomology.

Making Sense of the Bioeconomy: A Critical Analysis of EU Policy Narratives and Responses

Environmental Policy and Governance, EarlyView.
ABSTRACT The bioeconomy has become an increasingly popular concept in European Union (EU) policy, promising sustainable growth, job creation, and reduced environmental impacts. Yet its meaning remains contested, ambiguous, and politically charged. This study critically examines how EU bioeconomy policy narratives prior to 2025 construct this concept ...

Two‐Way Learning Through Evaluation: The Story of an Innovative Australian Aboriginal‐Led Initiative Strengthening Good Governance at the Cultural Interface

New Directions for Evaluation, EarlyView.
ABSTRACT In this article we share our story of using a developmental evaluation approach over seven years to facilitate two‐way learning between Yapa (Warlpiri language for Indigenous people from the Australian Western Desert region) and Kardiya (Warlpiri language for non‐Indigenous people).

Nodes and the Hodge conjecture [PDF]

Journal of Algebraic Geometry, 2004
The Hodge conjecture is shown to be equivalent to a question about the homology of very ample divisors with ordinary double point singularities. The infinitesimal version of the result is also discussed.

Investigating the Current Status, Influence Factors, and Challenges for Blended Teaching Readiness of Pre‐Service Teachers in China's Teacher Preparation Programs

Future in Educational Research, EarlyView.
ABSTRACT Blended teaching has become the new normal in modern education. Enhancing pre‐service teachers' readiness for blended teaching is crucial for adapting to the digital transformation of education and advancing instructional reform. However, pre‐service teachers' readiness for blended teaching has rarely been explored.

A cone conjecture for log Calabi-Yau surfaces

Forum of Mathematics, Sigma
We consider log Calabi-Yau surfaces $(Y, D)$ with singular boundary. In each deformation type, there is a distinguished surface $(Y_e,D_e)$ such that the mixed Hodge structure on $H_2(Y \setminus D)$ is split.

A counterexample to the Hodge conjecture for Kaehler varieties

, 2002
LatexSummary: The Hodge conjecture asks whether rational Hodge classes on a smooth projective manifolds are generated by the classes of algebraic subsets, or equivalently by Chern classes of coherent sheaves.

Clinicogenomic Features and Outcomes of Adenoid Cystic Carcinoma With Central Nervous System Metastases: A Single‐Institution Cohort Study

Head &Neck, EarlyView.
ABSTRACT Background Adenoid cystic carcinoma (ACC) is a rare malignancy with a propensity for perineural invasion and hematogenous spread. Central nervous system (CNS) involvement is uncommon, and detailed clinical and genomic data on this aspect of the disease remain limited.

On the Hodge Conjecture

This paper defines the volume of a solid as the cumulative sum of infinitesimal volume elements expanding or contracting diagonally from the origin, treating volume not as a static entity but as a dynamic manifold. Using spherical coordinates, the integration of the volume with respect to the diagonal length is performed, transforming the differential ...

A tropical approach to a generalized Hodge conjecture for positive currents [PDF]

, 2017
In 1982, Demailly showed that the Hodge conjecture follows from the statement that all positive closed currents with rational cohomology class can be approximated by positive linear combinations of integration currents.
