External validation, update and development of prediction models for pre-eclampsia using an Individual Participant Data (IPD) meta-analysis: the International Prediction of Pregnancy Complication Network (IPPIC pre-eclampsia) protocol. [PDF]
, 2017 Background: Pre-eclampsia, a condition with raised blood pressure and proteinuria is associated with an increased risk of maternal and offspring mortality and morbidity. Early identification of mothers at risk is needed to target management.

Fundamental limits of quantum-secure covert optical sensing [PDF]
, 2017 We present a square root law for active sensing of phase $\theta$ of a single pixel using optical probes that pass through a single-mode lossy thermal-noise bosonic channel.

Valuing Natural Space and Landscape Fragmentation in Richmond, VA [PDF]
, 2016 Hedonic pricing methods and GIS (Geographic Information Systems) were used to evaluate relationships between sale price of single family homes and landscape fragmentation and natural land cover. Spatial regression analyses found that sale prices increase

Adaptation dynamics of the quasispecies model
, 2008 We study the adaptation dynamics of an initially maladapted population evolving via the elementary processes of mutation and selection. The evolution occurs on rugged fitness landscapes which are defined on the multi-dimensional genotypic space and have ...

Water Resources Research, Volume 62, Issue 2, February 2026.Abstract Affordable autonomous soil sensors and IoT technology enable real‐time soil moisture monitoring, which offers opportunities for real‐time model calibration and irrigation optimization. We introduce an irrigation decision support system SWIM2 (Sensor Wielded Inverse Modeling of a Soil Water Irrigation Model), a digital twin that integrates ...

Measuring von Neumann entanglement entropies without wave functions [PDF]
, 2019 We present a method to measure the von Neumann entanglement entropy of ground states of quantum many-body systems which does not require access to the system wave function.

IET Communications, Volume 20, Issue 1, January/December 2026.This paper introduces a novel AMR method named IUDR‐Net to address the challenge of poor recognition accuracy under low SNR conditions. The method first employs the improved U‐Lite network to suppress the impact of noise effectively and then adopts the ResNet18‐1D network to perform the AMR task efficiently.

Clustering in Additive Mixed Models with Approximate Dirichlet Process Mixtures using the EM Algorithm [PDF]
, 2013 We consider additive mixed models for longitudinal data with a nonlinear time trend. As random effects distribution an approximate Dirichlet process mixture is proposed that is based on the truncated version of the stick breaking presentation of the ...

Sig2text: A Vision‐Language Model for Non‐Cooperative Radar Signal Parsing
IET Radar, Sonar &Navigation, Volume 20, Issue 1, January/December 2026.We propose Sig2text, a symbolic radar signal recognition and parameter estimation framework that treats waveform analysis as a parsing task using a vision‐language model. By integrating time‐frequency representations with a context‐free grammar and transformer‐based architectures, Sig2text accurately identifies complex modulation types and estimates ...
