Feline immunodeficiency virus (FIV) was isolated from a wild-caught Tsushima cat (Felis bengalensis euptilura), an endangered Japanese nondomestic subspecies of leopard cat (F. bengalensis). Phylogenetic analysis of the env gene sequences indicated that the FIV from the Tsushima cat belonged to a cluster of subtype D FIVs from domestic cats. FIVs from both the Tsushima cat and the domestic cat ...
تقریب نقاط ثابت نگاشت های ناانبساطی و تعمیم های آن ها در چند ده? اخیر رشد و نمو چشمگیری یافته است و هم اکنون یکی از زمینه های پژوهشی فعال و داغ محسوب می شود. توسع? کلاس نگاشت ها و تعمیم فضاهای مورد بحث، دو مسأل? مهم در این شاخ? پژوهشی می باشند. هدف این پایان نامه در راستای مسأل? اول، تقریب نقاط ثابت نگاشت های (i) مجانباً ناانبساطی (ii) ناانبساطی چند مقداری (iii) ...
The problems of sphere theorems in Riemannian geometry have yielded the beautiful results and the fruitful techniques for the study of global geometry (cf. [22]). The main purpose of this paper is to study sphere theorems for CAT(1)-spaces: When are CAT(1)-spaces homeomorphic to the sphere? The notion of CAT(κ)-spaces is introduced by Gromov ([11]) based on Alexandrov’s original notion, i.e., s...
As phylogenetic datasets have increased in size, site-heterogeneous substitution models such as CAT-F81 and CAT-GTR have been advocated in favor of other models because they purportedly suppress long-branch attraction (LBA). These models are two of the most commonly used models in phylogenomics, and they have been applied to a variety of taxa, ranging from Drosophila to land plants. However, ma...
Cardiac calcified amorphous tumor (CAT) is a rare nonneoplastic cardiac mass composed of calcium deposits in a background of amorphous degenerating fibrin material. Recently, cardiac CAT has gained considerable attention. A MEDLINE search of studies published until April 2017 using the term “cardiac calcified amorphous tumor” resulted in 54 articles, 49 of which were reported in the last 10 yea...
Stepwise degradation of the invariant chain (Ii) is required for the binding of antigenic peptides to MHC class II molecules. Cathepsin (Cat) L in the murine thymus and Cat S in peripheral APCs have both been implicated in the last step of Ii degradation that gives rise to the class II-associated invariant chain peptides (CLIP). Cat V has been recently described as highly homologous to Cat L an...
This research presents, and clarifies the application of two permutation algorithms, based on chaotic map systems, applied to a file speech signals. They are Arnold cat map-based algorithm, Baker’s algorithm. Both algorithms implemented same signal sample. Then, both premier encrypted histograms documented plotted. The amplitude values with time signals original recorded plotted against decrypt...
Increasingly, cat (Felis catus) advocates are establishing feeding stations or cat colonies in public parks and often claim that the well-fed cats pose little threat to wildlife populations. This claim was tested on East Bay Regional Park District land east of San Francisco, California during 1995 and 1996. Rodents were livetrapped on 100-trap grids for 8 nights at 9 sites (5 in 1995) in a no c...
background: radial movement of the arterial wall is a well-known indicator of the mechanical properties of arteries in arterial disease examinations. in the present study, two different motion estimation methods, based on the block-matching and maximum-gradient algorithms, were examined to extract the radial displacement of the carotid artery wall. methods: each program was separately implement...
