Synthesis of radar antenna patterns with linear beam scanning and amplitude signal processing

Весці Нацыянальнай акадэміі навук Беларусі: Серыя фізіка-тэхнічных навук, 2019
In radars with linear beam scanning the angular resolution is determined by the width of the antenna pattern. The traditional way to increase this resolution is to enlarge the size of the antenna aperture, which is limited by technical capabilities.

Subcritical switching dynamics and humidity effects in nanoscale studies of domain growth in ferroelectric thin films

, 2015
Ferroelectric domain switching in c-axis-oriented epitaxial Pb(Zr$_{0.2}$Ti$_{0.8}$)O$_3$ thin films was studied using biased scanning probe microscopy tips.

Transferrin receptor 1‐mediated iron uptake supports thermogenic activation in human cervical‐derived adipocytes

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.

Correlating the Evans index and bicaudate index with ventricle volume at the three kinds of scanning baselines

Brain Research Bulletin
Purpose: Evans' Index (EI) and Bicaudate Index (BCI), as two-dimensional linear indexes, are commonly used to evaluate ventricle size. This study is investigated the differences in linear measures at the three kinds of scanning baselines and their ...

Linear Robot as The Approach towards Individual Abdominal Ultrasound Scanning in Developing Countries?

International Journal of Advances in Telecommunications, Electrotechnics, Signals and Systems, 2015
In order to improve comfort in abdominal ultrasound scanning, reduce operator dependency and increase image resolution, a novel method for automatic ultrasound cervix scanning, especially for developing countries, has been developed.

Imaging spin flows in semiconductors subject to electric, magnetic, and strain fields

, 2004
Using scanning Kerr microscopy, we directly acquire two-dimensional images of spin-polarized electrons flowing laterally in bulk epilayers of n:GaAs.

Coherence scanning interferometry: linear theory of surface measurement [PDF]

Applied Optics, 2013
The characterization of imaging methods as three-dimensional (3D) linear filtering operations provides a useful way to compare the 3D performance of optical surface topography measuring instruments, such as coherence scanning interferometry, confocal and structured light microscopy.

Tau acetylation at K331 has limited impact on tau pathology in vivo

FEBS Letters, EarlyView.
We mapped tau post‐translational modifications in humanized MAPT knock‐in mice and in amyloid‐bearing double knock‐in mice. Acetylation within the repeat domain, particularly around K331, showed modest increases under amyloid pathology. To test functional relevance, we generated MAPTK331Q knock‐in mice.

The NOD3 software package: A graphical user interface-supported reduction package for single-dish radio continuum and polarisation observations

, 2017
The venerable NOD2 data reduction software package for single-dish radio continuum observations, developed for use at the 100-m Effelsberg radio telescope, has been successfully applied over many decades. Modern computing facilities call for a new design.
