Space Jam‐Ming: Generating Interstitial Space Using Fragmented Granular GelMA to Investigate Novel Paradigms of Cancer Metastasis

open access: yesAdvanced Science, EarlyView.
Microgels enable independent control of stiffness and interstitial space, overcoming limitations of conventional 3D hydrogels. Using fragmented gelatin methacryloyl microgels, we show that stiffness does not restrict non‐metastatic breast cancer growth, contrary to bulk hydrogels, and reveal the role of adherent‐to‐suspension transition in cancer ...

Accuracy assessment and improvement of SRTM, ASTER, FABDEM, and MERIT DEMs by polynomial and optimization algorithm: A case study (Khuzestan Province, Iran)

open access: yesOpen Geosciences, 2023
Satellite digital elevation models (DEMs) are used for decision-making in various fields. Therefore, evaluating and improving vertical accuracy of DEM can increase the quality of end products.

Modelling the spatial distribution of DEM Error [PDF]

open access: yes, 2005
Assessment of a DEM’s quality is usually undertaken by deriving a measure of DEM accuracy – how close the DEM’s elevation values are to the true elevation.

Leveraging Big Multitemporal Multisource Satellite Data and Artificial Intelligence for the Detection of Complex and Invisible Features: The Case of Extensive Irrigation Mapping

open access: yesArchaeological Prospection, EarlyView.
ABSTRACT The detection of buried or obscured archaeological features remains a central challenge in landscape archaeology, particularly in the irrigated floodplains of Mesopotamia where levees and canals formed the basis of complex agrarian systems. This study presents a deep learning–based approach for the large‐scale, automated detection of ancient ...

On Copernicus DEM–DTM and ICESat for Height and Biomass Retrieval of Tropical Forests

open access: yesIEEE Journal of Selected Topics in Applied Earth Observations and Remote Sensing
The Copernicus digital elevation model (DEM)–digital terrain model (DTM) difference was shown by Soja et al. (Soja et al., 2025) to be linearly correlated with above-ground biomass (AGB) for 11 test sites with a resolution of about 30 m for the ...

Transcriptomic Profiling in Skeletal Muscle Identifies Associations With Knee Osteoarthritis: The Study of Muscle, Mobility and Aging

open access: yesArthritis &Rheumatology, EarlyView.
Objective The association between skeletal muscle gene expression and knee osteoarthritis (OA) was examined among older adult participants of the Study of Muscle, Mobility and Aging (SOMMA). Methods Inclusion criteria included knee radiographs and bulk RNA sequencing in vastus lateralis muscle, resulting in 523 participants (56% female).

A Novel Framework for Validation of DSM Data Quality Based on Hyperspectral Topographic Correction

open access: yesRemote Sensing
Digital Surface Model (DSM) products play an indispensable role in mapping production and geospatial applications. Their importance in hyperspectral topographic correction is particularly critical, as they determine key terrain parameters such as slope ...

The Fast, the Steady and the Tenacious: Funding Pathways for Circular Start‐Ups

open access: yesBusiness Strategy and the Environment, EarlyView.
ABSTRACT Circular start‐ups (CSUs) are critical for unlocking the circular economy, yet they face persistent barriers in accessing finance. Despite growing interest from policymakers and financing institutions, little empirical evidence explains how these ventures pursue and secure funding.
