A Transcriptionally Distinct Intermediate Activation State Precedes Langerhans Cell Migration From the Epidermis

open access: yesAdvanced Science, EarlyView.
A transcriptionally distinct intermediate Langerhans cell state is identified between steady and migratory populations during skin injury. Integrated single‐cell transcriptomics, flow cytometry, and intravital imaging reveal state‐specific markers and implicate complement signaling, particularly C3, in regulating Langerhans cell accumulation near ...

Biallelic PAX6 Variants in an Adult With Severe Microphthalmia and Preserved Intellectual Function

open access: yesAmerican Journal of Medical Genetics Part A, EarlyView.
ABSTRACT PAX6 encodes a dosage‐sensitive transcription factor that is essential for eye development. Heterozygous PAX6 disease is well characterized, but biallelic disease is extremely rare and has been associated with anophthalmia, severe brain malformations, and perinatal lethality.

Validation of Sentinel-1A SAR Coastal Wind Speeds Against Scanning LiDAR

open access: yesRemote Sensing, 2017
High-accuracy wind data for coastal regions is needed today, e.g., for the assessment of wind resources. Synthetic Aperture Radar (SAR) is the only satellite borne sensor that has enough resolution to resolve wind speeds closer than 10 km to shore but the Geophysical Model Functions (GMF) used for SAR wind retrieval are not fully validated here. Ground

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 ...

Sentinel-1 observation frequency significantly increases burnt area detectability in tropical SE Asia

open access: yes, 2020
Frequent cloud cover in the tropics significantly affects the observation of the surface by satellites. This has enormous implications for current approaches that estimate greenhouse gas (GHG) emissions from fires or map fire scars.
