Autonomous UAV 3D Reconstruction using Prediction-Based Next Best View [PDF]

open access: yesISPRS Annals of the Photogrammetry, Remote Sensing and Spatial Information Sciences
High-quality 3D reconstruction of infrastructure using UAVs is essential for inspection, monitoring, and digital twin applications. Traditional flight planning methods rely on predefined paths and often struggle with complex geometries, leading to ...

Earth Observation

open access: yes, 2012
Today, space technology is used as an excellent instrument for Earth observation applications. Data is collected using satellites and other available platforms for remote sensing. Remote sensing data collection detects a wide range of electromagnetic energy which is emitting, transmitting, or reflecting from the Earth's surface.

Citizen Science for Observing and Understanding the Earth [PDF]

open access: yes, 2018
Citizen Science, or the participation of non-professional scientists in\ud a scientific project, has a long history—in many ways, the modern scientific\ud revolution is thanks to the effort of citizen scientists. Like science itself, citizen\ud science is influenced by technological and societal advances, such as the rapid\ud increase in levels of ...

Epigenetic reprogramming of lineage switching in cancer

open access: yesFEBS Letters, EarlyView.
Cancer cells rarely commit to a single identity. Epigenetic mechanisms and tumor microenvironment cues push epithelial cells toward flexible, hybrid states that can shift into mesenchymal, neuroendocrine, or stem‐like fates, driving metastasis, drug resistance, and tumor heterogeneity. Targeting the epigenetic regulators behind these transitions, using

On the foundations of Earth foundation models

open access: yesCommunications Earth & Environment
Foundation models have enormous potential in advancing Earth sciences. However, current approaches may not be optimal, as they focus only on a few basic features of a desirable Earth foundation model.

The microbiome in human skin aging

open access: yesFEBS Letters, EarlyView.
Age‐related skin changes encompass the well‐known visible phenotypic alterations, together with microbiome dysbiosis and a series of molecular aging hallmarks. These hallmarks characterize not only a fully stablished aged phenotype but also the skin aging process itself.

Earth tides, earthquake occurrence and earth deformation

open access: yes, 2010
An analysis of Earth deformation, earthquakes and tides has been undertakenusing Earth tide and interferometric SAR data from ESA satellites. The abilityof Earth tides to trigger earthquakes has been investigated by measuring thestatistical relationship ...

Autophagy and mitophagy in pancreatic β‐cell homeostasis and their involvement in diabetes pathophysiology

open access: yesFEBS Letters, EarlyView.
This review focuses on the role of autophagy and mitophagy in maintaining pancreatic β‐cell function and homeostasis. We discuss how genetic defects affecting these pathways contribute to the development of type 1, type 2, monogenic, and gestational diabetes. We further explore their potential as therapeutic targets. Created in BioRender.

Earth Observation from Elliptical Orbits with Very Low Altitude Perigee [PDF]

open access: yes, 2003
Small Earth Observation satellites can obtain higher resolution with smaller payloads when operating at very low altitude. The life limiting effect of residual atmospheric drag can be reduced flying elliptical, low-altitude perigee orbits, with perigee ...

Ligand‐dependent transcriptional heterogeneity in cell cycle gene expression delays G1/S entry

open access: yesFEBS Letters, EarlyView.
EGF and HRG induce distinct G1/S progression programs in ErbB2‐amplified BT474 breast cancer cells. Despite activating the potent ErbB2–ErbB3 heterodimer, HRG does not accelerate cell‐cycle entry. Instead, EGF promotes earlier restriction‐point passage via ERK–FOS signaling, whereas HRG activates the AKT–MYC axis, driving transcriptional heterogeneity ...
