In testing the equality of several variances, it has been shown that the probabilities given by standard tests, derived on the assumption that the samples are drawn from a normal parent population, are subject to large errors when the normality assumption is not satisfied. Therefore a modified form of the F test for testing equality of two variances, when the means are knoim has been developed....

Permanent bilateral occlusion of the common carotid arteries (2VO) in the rat has been established as a valid experimental model to investigate the effects of chronic cerebral hypoperfusion on cognitive function and neurodegenerative processes. Our aim was to compare the cognitive and morphological outcomes following the standard 2VO procedure, in which there is concomitant artery ligation, wit...

A novel inclusion complexes nanofibrous membrane fluorescent sensor was prepared for recognizing F- via electrospinning and host–guest interaction. The host α-cyclodextrin on the surface of electrospun nanofiber is assembled into guest azobenzene molecule which modified with probe, formation complex fixed without external force, to prepare a controllable composite detection. exhibited favourabl...

Ischemic diseases represent a challenging worldwide health burden. The current study investigated the therapeutic potential of genetically modified human placenta‑derived mesenchymal stem cells (hPDMSCs) with basic fibroblast growth factor (FGF2) and platelet‑derived growth factor‑BB (PDGF‑BB) genes in hindlimb ischemia. Mesenchymal stem cells obtained from human term placenta were transfected ...

During World War I there was much lamentation over the "defects of the draft," and the word "shocking" was in frequent use with reference to the condition of a large proportion of men of military age. When, more recently, it became necessary again for society to interpose a shield of human lives between itself and disaster, its cerebral cells once more became agitated over the report that its y...

In this paper, we give new sparse interpolation algorithms for black box polynomial f whose coefficients are from a finite set. In the univariate case, we recover f from one evaluation of f(β) for a sufficiently large number β. In the multivariate case, we introduce the modified Kronecker substitution to reduce the interpolation of a multivariate polynomial to the univariate case. Both algorith...

We explore a new horizon of modified gravity from the viewpoint of the particle physics. As a concrete example, we take the F (R) gravity to raise a question: can a scalar particle (“scalaron”) derived from the F (R) gravity be a dark matter candidate? We place the limit on the form of function F (R) from the constraint on the scalaron as a dark matter. The role of the screening mechanism and c...

Two new species of Fibuloides are described from eastern Thailand: F. tratensis Jaikla and Pinkaew, n.sp., and F. bulla Jaikla and Pinkaew, n.sp. Males of F. tratensis have modified labial palpi with specialized scales that have not been reported for other Tortricidae. Descriptions and illustrations of adults and genitalia are provided for the two new species collected from Trat Agroforestry Re...

We shall investigate the properties of a congruence of geodesics in the framework of Palatini f(R) theories. We shall evaluate the modified geodesic deviation equation and the Raychaudhuri’s equation and show that f(R) Palatini theories do not necessarily lead to attractive forces. Also we shall study energy condition for f(R) Palatini gravity via a perturbative analysis of the Raychaudhuri’s e...
