High-Precision Geolocation of SAR Images via Multi-View Fusion Without Ground Control Points
Remote SensingSynthetic Aperture Radar (SAR) images generated via range-Doppler (RD) model-based geometric correction often suffer from non-negligible systematic geolocation errors due to cumulative impacts of platform positioning inaccuracies, payload time ...

A High-Precision Positioning Method Without Ground Control Points for Mosaic Aerial Survey Camera [PDF]
The International Archives of the Photogrammetry, Remote Sensing and Spatial Information SciencesMosaic aerial survey cameras facilitate large-format imaging by integrating multiple lenses and sensors. Nevertheless, the inherent complexity of their structural design gives rise to collimation axis eccentricity errors between the Position and ...

Protein pyrophosphorylation by inositol pyrophosphates — detection, function, and regulation
FEBS Letters, EarlyView.Protein pyrophosphorylation is an unusual signaling mechanism that was discovered two decades ago. It can be driven by inositol pyrophosphate messengers and influences various cellular processes. Herein, we summarize the research progress and challenges of this field, covering pathways found to be regulated by this posttranslational modification as ...

FEBS Letters, EarlyView.We reconstituted Synechocystis glycogen synthesis in vitro from purified enzymes and showed that two GlgA isoenzymes produce glycogen with different architectures: GlgA1 yields denser, highly branched glycogen, whereas GlgA2 synthesizes longer, less‐branched chains.

FEBS Letters, EarlyView.In this study, we found that human cervical‐derived adipocytes maintain intracellular iron level by regulating the expression of iron transport‐related proteins during adrenergic stimulation. Melanotransferrin is predicted to interact with transferrin receptor 1 based on in silico analysis.

Calpain small subunit homodimerization is robust and calcium‐independent
FEBS Letters, EarlyView.Calpains dimerize via penta‐EF‐hand (PEF) domains. Using single‐molecule force spectroscopy, we measured the strength and kinetics of PEF–PEF homodimer binding. The interaction is robust, shows a transient conformational step before dissociation, and remains largely insensitive to Ca2+.

Проблеми створення, випробування, застосування та експлуатації складних інформаційних систем, 2019 Every year, unmanned aircraft systems are increasingly used in both the civilian and military spheres. Stable communication with an unmanned aerial vehicle is provided by high-precision pointing of the antenna of the ground control point. In the automatic tracking mode of an unmanned aerial vehicle, the antenna guidance is carried out by the automatic ...
