The cytological composition of the proliferative zones in the fetal monkey occipital lobe was examined at the light and electron microscopic levels by immunoperoxidase localization of glial fibrillary acid protein (GFA), a protein that is present in astrocytes and radial glial cells but not neurons. During the peak of neurogenesis at embryonic day 80, two distinct classes of proliferative cells...
در این مطالعه تلاش میشود با استفاده از مدل ارزیابی عملکرد آنالیز عامل خاکستری (GFA) به عوامل عمده مؤثر بر عملکرد شرکتها دست یافت و با تخصیص امتیاز شرکتها را رتبهبندی نمود. GFA ترکیبی از تئوری خاکستری و تحلیل عاملی است که قابلیت ارزیابی عملکرد بنگاههای تجاری را دارد، همچنین بهدلیل اینکه صنعت فلزات اساسی ایران صنعتی در حال رشد تلقی میشود این مطالعه مدل GFA را با شرکتهای فعال در صنعت فلزات...
To clarify the relationship between glass-forming ability (GFA) and local atomic structure of Pd-based metallic glasses, structures an amorphous Pd40Cu40P20 (PCP) were investigated using same methods as for Pd40Ni40P20 (PNP) glass, i.e., by a combination anomalous X-ray scattering, neutron diffraction, reverse Monte Carlo modeling. From comparison results PNP with excellent GFA PCP worse GFA, i...
Mexylaminotriazine derivatives form molecular glasses with outstanding glass-forming ability (GFA), high resistance to crystallization (glass kinetic stability, GS), and a glass transition temperature (Tg) above room temperature that can be conveniently modulated by selection of the headgroup and ancillary groups. A common feature of all these compounds is their secondary amino linkers, suggest...
BACKGROUND The majority of studies investigating the neural mechanisms underlying treatment-induced recovery in aphasia have focused on the cortical regions associated with language processing. However, the integrity of the white matter connecting these regions may also be crucial to understanding treatment mechanisms. OBJECTIVE This study investigated the integrity of the arcuate fasciculus ...
In this paper, a new deep learning network named as graph-based point tracker (GPT) is proposed for 3D object tracking in clouds. GPT not based on Siamese applied to template and search area, but it the transfer of target clue from area. end-to-end trainable. has two modules: graph feature augmentation (GFA) improved (ITC) module. The key idea GFA exploit one-to-many relationship between area p...
In this note first by considering the notion of general fuzzy automata (for simplicity GFA), we define the notions of direct product, restricted direct product and join of two GFA. Also, we introduce some operations on (Fuzzy) sets and then prove some related theorems. Finally we construct the general fuzzy recognizers and recognizable sets and give the notion of (trim) reversal of a given GFA....
The glass-forming ability (GFA) of alloys with a high-solvent content such as soft magnetic Fe-based and Al-based alloys is usually limited due to strong formation of the solvent-based solid solution phase. Herein, we report that the GFA of soft magnetic Fe-based alloys (with >70 at.% Fe to ensure large saturation magnetization) could be dramatically improved by doping with only 0.3 at.% Cu whi...
The glass-forming ability (GFA) and thermal stability of (Zr65Al7:5Cu27:5)100 xTix (x 1⁄4 0 15; in at%) alloys have been investigated. It was revealed that a certain amount of Ti addition could improve the GFA of Zr65Al7:5Cu27:5 alloy effectively. The best bulk metallic glass (BMG) forming composition was found at (Zr65Al7:5Cu27:5)93Ti7. Bulk glassy samples with diameter of 7mm were made by mea...
Glass is a freezing phase of a deeply supercooled liquid. Despite its simple definition, the origin of glass forming ability (GFA) is still ambiguous, even for binary Cu-Zr alloys. Here, we directly study the stability of the supercooled Cu-Zr liquids where we find that Cu64Zr36 at a supercooled temperature shows deeper undercoolability and longer persistence than other neighbouring composition...
