SPARTA v2.2.2: graph structural operators and null models for characterizing spatial tissue architecture in spatial omics (code, node tables and results)

SPARTA poses two graph structural operators on one spatial graph: a source–sink minimum cut for migrating immune cells and a screened diffusion–absorption field for a molecular-sized in silico probe, with calibrated surrogate tests, patient-level inference and structural null models. Release v2.2.2 accompanies the manu...

Diffusion Models and the Koopman Operator for Spacecraft Trajectory Optimization

Drug Permeation Dataset Across Diverse Chemical Space Using PermeaPad and High-Throughput Plate Reader Assays

Abstract Purpose High-throughput permeation assays are essential tools in drug discovery for identifying small molecules with favorable permeability, yet quantifying their transport kinetics across biomimetic membranes often relies on resource-intensive chromatographic methods. Here, we propose a simplified calibration...

Steady-state bifurcation analysis of a herbivore-vegetation reaction–diffusion model with memory effect

Spatial memory is a crucial cognitive ability that affects animals’ perception and judgment, and it has garnered widespread attention. However, its underlying mechanisms have not been fully understood. This paper constructs a herbivore-vegetation model with spatial memory effect, in which the memory effects are describ...

Synthetic Spacecraft Telemetry Dataset with Physics-Constrained Validation

This dataset contains synthetically generated spacecraft telemetry for Low Earth Orbit (LEO) missions using a physics-constrained tabular diffusion framework. The dataset includes spacecraft telemetry parameters generated under different space-weather conditions, including Quiet, Moderate, and Storm scenarios. The tele...

Ferroelectric polymer mediated bipolar memristive switching in reduced graphene oxide nanocomposite device

Two-terminal energy-efficient resistive random-access memory (RRAM) devices are key enablers for modern electronic technologies. Graphene based materials have drawn promising attention recently in scientific community due to its phenomenal attributes in electronic memory devices. In this study, graphene oxide (GO) and...

Efficient latent-vision enabled generative data augmented pipeline for medical image analysis with hybrid deep learning approach

Medical image analysis is an important process involved in diagnosing diseases, but a lack of data, class imbalance, and poor interpretability of deep learning models hamper it. In this study, these problems are overcome by proposing a hybrid generative data-augmented method for the classification of breast cancer and...

A Mass-Conserving Spatiotemporal Graph ODE Model for Multi-Step Streamflow Forecasting in a Sparsely Gauged Semi-Arid Basin

Semi-arid loess basins in the middle Yellow River have rapid runoff responses, short hydrological memory, and sparse gauging networks, so pooled metrics across all stations can conceal forecast failures in low-flow tributaries and during dry periods. This study proposes DaSTGODE, a data-augmented spatiotemporal graph o...
