Multitemporal Unmixing of Medium-Spatial-Resolution Satellite Images: A Case Study Using MERIS Images for Land-Cover Mapping

2011

Data from current medium-spatial-resolution imaging spectroradiometers are used for land-cover mapping and land-cover change detection at regional to global scales. However, few landscapes are homogeneous at these scales, and this creates the so-called mixed-pixel problem. In this context, this study explores the use of the linear spectral mixture model to extract subpixel land-cover composition from medium-spatial-resolution data. In particular, a time series of MEdium Resolution Imaging Spectrometer (MERIS) full-resolution (FR; pixel size of 300 m) images acquired over The Netherlands is used to illustrate this study. The Netherlands was selected because of the following: 1) the fragmenta…

Extracellular membrane vesicles can mediate intercellular transfer of molecules

2012

Many eukaryotic cell types, including neural cells, release into the extracellular environment vesicles of different sizes and composition. Neurons and astrocytes shed extracellular vesicles which contain FGF2 and VEGF and could be involved in interaction with endothelial cells, to form the blood-brain barrier. Also brain tumor cells, such as glioblastomas, release vesicles in the extracellular space. Microvesicles (MVs) shed from G26/24 oligodendro¬glioma cells were previously reported to contain FAS-L and to cause a reproducible, dose-dependent, inhibitory effect on neurite outgrowth, and neuronal apoptosis, when added to primary cultures of rat cortical neurons. More recently, they were …

Jēkabpils pilsētas apbūves attīstība 1919.-1940.g.

2018

Bakalaura darba mērķis ir izpētīt Jēkabpils pilsētas apbūves attīstību laika posmā no 1919. gada līdz 1940.gadam. Jēkabpils pilsētas apbūve laikā no 1919. līdz 1940. gadam turpināja attīstīties tipiski Latvijas mazpilsētām pilsētām, saglabājot savu raksturu un īpatnības, ievērojot Latvijas Republikas būvniecības noteikumus, pieejamos finansu līdzekļus un celtniecības materiālus. Par Jēkabpils pilsētu ir veikti novadpētnieciski pētījumi, kas ietver arī pilsētas apbūves attīstību, taču tie galvenokārt ir apkopojoša rakstura un sniedz tikai informatīvu ieskatu galvenajās apbūves norisēs, tāpēc darbs būtu noderīgs attiecīgā reģiona novadpētniecības attīstībā. Pētījuma rezultātā tika izveidota J…

Astrometry and photometry of digitized plates of Baldone Schmidt telescope

2021

Abstract During the 40-year photographic period of astronomical observations, the Baldone Astrophysical Observatory has accumulated more than 22,000 direct and 2,500 spectral images. In 2018, the digitization of direct astrophoto images with a resolution of 1200 dpi was completed. A processing methodology for obtaining the equatorial coordinates and photometric characteristics of the objects recorded in digitized astronegatives using the LINUX/MIDAS/ROMAFOT environment has been developed at the Main Astronomical Observatory of the National Academy of Sciences of Ukraine. Program package with success already works in seven observatories. A description of the operation of this program complex…

Cajal–Retzius and Subplate Cells

2013

The laminar and columnar organization of the mature cerebral cortex is determined by a variety of early developmental processes. Two distinct populations of early generated preplate neurons play key roles in corticogenesis. Cajal–Retzius neurons, located in the marginal zone (later layer I), control the formation of neocortical layers by releasing the extracellular matrix protein reelin, which serves as a guiding signal for migrating neurons. Subplate neurons in the lower neocortical layer play an active role in transient synaptic circuits and influence early cortical plasticity and the maturation of the columnar architecture. Both neuronal cell populations serve as transient synaptic targe…

Chicken genome analysis reveals novel genes encoding biotin-binding proteins related to avidin family

2005

Background A chicken egg contains several biotin-binding proteins (BBPs), whose complete DNA and amino acid sequences are not known. In order to identify and characterise these genes and proteins we studied chicken cDNAs and genes available in the NCBI database and chicken genome database using the reported N-terminal amino acid sequences of chicken egg-yolk BBPs as search strings. Results Two separate hits showing significant homology for these N-terminal sequences were discovered. For one of these hits, the chromosomal location in the immediate proximity of the avidin gene family was found. Both of these hits encode proteins having high sequence similarity with avidin suggesting that chic…
