Building a 2.5D Digital Elevation Model from 2D Imagery [PDF]

open access: yes
When projecting imagery into a georeferenced coordinate frame, one needs to have some model of the geographical region that is being projected to. This model can sometimes be a simple geometrical curve, such as an ellipse or even a plane.

Lung Microphysiological System Validates Novel Cell Therapy for Acute Respiratory Distress Syndrome

open access: yesAdvanced Biology, EarlyView.
This study aims to evaluate the efficacy of primed mesenchymal stem cells (pMSCs) as an alternative treatment for Acute Respiratory Distress Syndrome (ARDS), based on a novel lung microphysiological system (MPS) to test the efficacy of pMSCs over the standard treatment, Dexamethasone.

Infrared Neural Stimulation Elicits Distinct Molecular Pathways in Astrocytes Based on Laser Pulse Parameters

open access: yesAdvanced Biology, EarlyView.
Infrared (IR) light evokes distinct calcium and water transport responses in astrocytes, depending on stimulation duration and protocol. This study uses widefield imaging and pharmacology to reveal differential engagement of astroglial signaling pathways.

Application of digital terrain data to quantify and reduce the topographic effect on LANDSAT data [PDF]

open access: yes
Integration of LANDSAT multispectral scanner (MSS) data with 30 m U.S. Geological Survey (USGS) digital terrain data was undertaken to quantify and reduce the topographic effect on imagery of a forested mountain ridge test site in central Pennsylvania ...

Osteogenic Effects of Ion Released from Biodegradable Metallic Magnesium and Calcium Coating

open access: yesAdvanced Biology, EarlyView.
This study explores how magnesium–calcium coatings on titanium promote osteogenesis by releasing ions and elevating pH during degradation. Using osteoblast‐like cells, the research demonstrates that both ion release and pH changes contribute to cell proliferation, differentiation, and mineralization, offering new insights into the design of bioactive ...

Scale factor and digital elevation analysis for hydrological studies [PDF]

open access: yes, 2007
The digital elevation model (DEM) is usually used to express a topographic surface in three dimensions and to imitate essential natural geography. The DEM is a model of the elevation surface, which is subject to errors.

Machine Learning Applied to High Entropy Alloys under Irradiation

open access: yesAdvanced Engineering Materials, EarlyView.
Designing alloys for extreme environments demands fast, trustworthy prediction. This review charts how machine learning—especially machine‐learned interatomic potentials and predictive models based on experiment‐informed datasets—captures the complexity of high‐entropy alloys in extreme environments, predicts phase formation, mechanical properties, and

A daily, 1 km resolution data set of downscaled Greenland ice sheet surface mass balance (1958–2015) [PDF]

open access: yes, 2017
This study presents a data set of daily, 1 km resolution Greenland ice sheet (GrIS) surface mass balance (SMB) covering the period 1958–2015. Applying corrections for elevation, bare ice albedo and accumulation bias, the high-resolution product is ...
