Assessment of Electromagnetic Tracking Accuracy for Endoscopic Ultrasound

, 2016
Endoscopic ultrasound (EUS) is a minimally-invasive imaging technique that can be technically difficult to perform due to the small field of view and uncertainty in the endoscope position.

Spatiotemporal and quantitative analyses of phosphoinositides – fluorescent probe—and mass spectrometry‐based approaches

FEBS Letters, EarlyView.
Fluorescent probes allow dynamic visualization of phosphoinositides in living cells (left), whereas mass spectrometry provides high‐sensitivity, isomer‐resolved quantitation (right). Their synergistic use captures complementary aspects of lipid signaling. This review illustrates how these approaches reveal the spatiotemporal regulation and quantitative

Disease Severity Estimates-Effects of Rater Accuracy and Assessment Methods for Comparing Treatments

, 2015
Assessment of disease severity is required for several purposes in plant pathology; most often, the estimates are made visually. It is established that visual estimates can be inaccurate and unreliable.

Hyperosmotic stress induces PARP1‐mediated HPF1‐dependent mono(ADP‐ribosyl)ation

FEBS Letters, EarlyView.
Sorbitol‐induced hyperosmotic stress rapidly induces reversible mono(ADP‐ribosyl)ation (MARylation) on PARP1 without the signs of genotoxic signaling. We show that PARP1 autoMARylation is HPF1 dependent and forms hydroxylamine‐resistant O‐glycosidic linkages.

Dynamic Monitoring and Analysis of Land-Use and Land-Cover Change Using Landsat Multitemporal Data in the Zhoushan Archipelago, China

IEEE Access, 2020
Rapid urbanization, marked by massive land-use and land-cover change (LUCC) and explosive population growth, has a significant impact on human activities. To provide a comprehensive understanding of the characteristics of LUCC in the Zhoushan Archipelago,

An unexpected alternative viologen electron mediator site in tungsten‐containing formate dehydrogenase

FEBS Letters, EarlyView.
An unexpected alternative interaction site for ethyl viologen was identified in formate dehydrogenase 1 from Methylorubrum extorquens. Combined mutagenesis, kinetic analysis, and docking revealed that aromatic residues near an iron–sulfur cluster enable flavin mononucleotide‐independent electron transfer, offering a framework for engineering improved ...

BUILDING EXTRACTION FROM VERY HIGH-RESOLUTION SATELLITE IMAGES FOR MAP UPDATING IN EGYPT [PDF]

JES: Journal of Engineering Sciences, 2020
Robust building detection from satellite images has been a subject of interest for several decades. Very High Resolution (VHR) satellite images support the efficient extraction of manmade objects.

ASSESSMENT OF THE ACCURACY OF PHOTOPLAN

Herald of Polotsk State University. Series F. Civil engineering. Applied sciences, 2022
When using analog aerial cameras, photomaps were assembled from transformed images. If the elevation of the points of the terrain made it possible to obtain acceptable distortions for the relief, then they were transformed into one zone. Otherwise, the transformation was performed by zones, allowing displacements in each zone of no more than 0.4 mm. In

Assessment of the accuracy of measures in the 1829 southern double star catalogue of James Dunlop [PDF]

, 2022
In 1829 James Dunlop published the first southern double star catalogue of some 253 double stars. The accuracy of this catalogue has been determined by using Aladin to cross-match them with Gaia DR2 and estimate their positional (right ascension ...

Cell geometry and membrane protein crowding constrain Escherichia coli growth rate, overflow metabolism, respiration, and maintenance energy

FEBS Letters, EarlyView.
The physical dimensions and shape of bacterial cells define the surface area available to acquire nutrients and the volume available for synthesizing proteins and DNA. Here, we use computational systems biology to decode the importance of cell geometry as a major determinant of prokaryotic phenotype, including growth rate and metabolic efficiency. This
