Experimental setups using two-arm and o 60 four-arm prolate-spheroidal IRAs are used to obtain better focusing for a prolate-spheroidal IRA and these results are compared with analytical results in [1] for comparison. This paper presents a summary of the experimental setup and the dimensions of these experiments are based on [1, 2]. These setups were motivated by a biological application [3]. T...

Alternative expressions for calculating the prolate spheroidal radial functions of the first kind R^] (c, £) and their first derivatives with respect to £ are shown to provide accurate values, even for low values of I — m where the traditional expressions provide increasingly inaccurate results as the size parameter c increases to large values. These expressions also converge in fewer terms tha...

Reported here are both STM images and spatially resolved tunneling spectra of four different polyoxometalate (POM) structural class members: Keggin structure, H(3)[PW(12)O(40)] (spherical); Finke-Droege (FD) structure, Na(16)[Cu(4)(H(2)O)(2)(P(2)W(15)O(56))(2)] (prolate spheroidal); Wells-Dawson (WD) structure, H(7)[P(2)Mo(17)VO(62)] (prolate spheroidal); and Pope-Jeannin-Preyssler (PJP) struct...

Spheroidal and fritted particles of three size classes from closein fallout samples collected from Small Boy were separated by hand. Analysis of spheroidal and fritted groups fror the > lU00-u and the 35O-7OO-U size classes showed that spheroidal particles had higher specific activities than the fritted particles; however this difference was less pronounced for the smaller size groups. Contrary...

In this paper, we jointly consider the inhomogeneity and spatial dimension in large scale wireless networks. We study the effects of topology on the throughput capacity. This problem is inherently difficult since it is complex to handle the interference caused by simultaneous transmission. To solve this problem, we, according to the inhomogeneity of topology, divide the transmission into intra-...

From the photometric results presented in this communication it appears that contrary to some earlier indications the open spirals, with their supergiant stars and superficial structure of spiral arms, are not appreciably larger than spheroidal galaxies, which seem to be devoid of highly luminous stars and free of distributional irregularities. It follows that if in the course of time spiral ar...

Galaxies exhibit a sequence of various morphological types, i.e., the Hubble sequence, and they are basically composed of spheroidal components (elliptical galaxies and bulges in spiral galaxies) and disks. It is known that spheroidal components are found only in relatively massive galaxies with M = 10M⊙, and all stellar populations in them are very old, but there is no clear explanation for th...

The newly formed generative cell of the pollen grain of the African blood lily is spheroidal after its detachment from the pollen wall. Plastids are almost always excluded from the generative cell, while dictyosomes, mitochondria, ribosomes, endoplasmic reticulum, and microtubules are present throughout development of the cell. During the time that the generative cell is spheroidal, microtubule...

Pollen morphology and the degree of pollen variability within nine species and two varieties of Oxalis species from Buenos Aires Province (Argentina) were studied using light microscopy (LM), scanning electron microscopy (SEM) and transmission electron microscopy (TEM). Oxalis pollen grain is generally 3-colpate and the shape is prolate spheroidal, oblate spheroidal or spheroidal. The exine is ...
