Modular equations for hyperelliptic curves

Mathematics of Computation, 2004
We dene modular equations describing the ‘-torsion subgroups of the Jacobian of a hyperelliptic curve. Over a nite base eld, we prove factorization properties that extend the well-known results used in Atkin’s improvement of Schoof’s genus 1 point ...

Subglacial landscape formation and sediment discharge: relating basal conditions to bedform dimensions and properties at Rutford Ice Stream, West Antarctica

Boreas, EarlyView.
Basal conditions that facilitate fast ice flow are still poorly understood and their parameterization in ice‐flow models results in high uncertainties in ice‐flow and consequent sea‐level rise projections. Direct observations of basal conditions beneath modern ice streams are limited due to the inaccessibility of the bed.

Cord blood levels of insulin‐like growth factor‐1 and insulin‐like growth factor binding protein‐3 correlate with perinatal brain development in fetal congenital heart disease

Ultrasound in Obstetrics &Gynecology, Volume 66, Issue 2, Page 200-209, August 2025.
Abstract Objectives Neonates with critical congenital heart disease (CCHD) are at risk for adverse early brain development and long‐term neurodevelopmental sequelae. Insulin‐like growth factor‐1 (IGF‐1) and insulin‐like growth factor binding protein‐3 (IGFBP‐3) are essential contributors to brain growth and maturation.

Algebraic Curves and Cryptography

, 2010
It is by now a well-known paradigm that public-key cryptosystems can be built using finite Abelian groups and that algebraic geometry provides a supply of such groups through Abelian varieties over finite fields.

“Which Projections Do I Use?” Strategies for Climate Model Ensemble Subset Selection Based on Regional Stakeholder Needs

Geophysical Research Letters, Volume 52, Issue 13, 16 July 2025.
Abstract Climate model (or earth system model) projections are increasingly used for climate adaptation planning and impact assessments. As part of this process, many end‐users evaluate a subset of downscaled climate projections without being aware of the implications of downscaling methodology for statistics or event outcomes.

Emulation With Uncertainty Quantification of Regional Sea‐Level Change Caused by the Antarctic Ice Sheet

Journal of Geophysical Research: Machine Learning and Computation, Volume 2, Issue 2, June 2025.
Abstract Projecting regional sea‐level change under various climate‐change scenarios typically involves running forward simulations of the Earth's gravitational, rotational and deformational (GRD) response to ice‐mass change, which requires substantial computational cost if applied to probabilistic frameworks requiring thousands to millions of samples.

Is Hot Drought a Risk in the US Mid‐Atlantic? A Potomac Basin Case Study

JAWRA Journal of the American Water Resources Association, Volume 61, Issue 3, June 2025.
ABSTRACT Interannual variability of streamflow will increase under a future climate, but at the regional scale, there is uncertainty regarding changes in drought severity, and in particular, changes in extreme hydrological drought that could necessitate new water supply infrastructure.

Elliptical Silicon Nanowire Covered by the SEI in a 2D Chemo‐Mechanical Simulation

Batteries &Supercaps, Volume 8, Issue 5, May 2025.
Silicon anodes are a promising next‐generation anode material, for which consideration of the chemo‐mechanical interaction is crucial. This publication investigates an elliptical silicon nanowire with surrounded SEI comparing a soft and stiff SEI scenario.

Historical frequency of plants in nursery catalogues predicts likelihood of naturalization in ornamental species

Ecological Applications, Volume 35, Issue 3, April 2025.
Abstract Ornamental horticulture is the major pathway of non‐native plant species introductions worldwide. Historic nursery catalogues capture a long‐term view of introduction effort arising from garden plantings and are a powerful resource for understanding why some introduced ornamental species subsequently jump the garden fence. Analyses of historic

Lake chlorophyll responses to drought are related to lake type, connectivity, and ecological context across the conterminous United States

Limnology and Oceanography, Volume 70, Issue 4, Page 941-958, April 2025.
Abstract Local and regional‐scaled studies point to the important role of lake type (natural lakes vs. reservoirs), surface water connectivity, and ecological context (multi‐scaled natural settings and human factors) in mediating lake responses to disturbances like drought.
