From chaos to order: the life history of Hannaea inaequidentata (Lagerstedt) Genkal and Kharitonov (Bacillariophyta), from initial cells to vegetative cells

This study presents observations on three species of Hannaea and documents and illustrates the life history of H. inaequidentata. We have divided the life history of H. inaequidentata into the following four series of successive stages: auxospore, initial cell, pre-normal vegetative cell, and normal vegetative cell. The initial cell has a cylinder-like and a frequently twisted outline, a longitudinal perizonium wholly covering the valve surface, and a disc-shaped incunabular scale, but lacks any transverse perizonium bands. The pre-normal vegetative cell cannot form ribbon-like colonies, has a wide variety of irregular outlines and is composed of two cell types: one with its epivalve composed of either the initial epivalve or the initial hypovalve, its hypovalve being newly formed, the other with both its epivalve and hypovalve newly formed. The normal vegetative cell has a regular outline and exhibits a significant length reduction so that the largest valve is at least four times longer than the smallest. From initial cell to normal vegetative cell, the developmental sequence goes from ‘chaos to order’ as happens in many phenomena in the universe. The lack of transverse perizonium bands may be the cause of the initial ‘chaos’ process during its developing period from the initial cell to the normal vegetative cell. The development of frustule/valve shape, central area, sternum, virga, vimine, rimoportula and ocellulimbus etc. during the life circle is summarised. In the genus Hannaea, some taxa lack the strongly buttressed central area as in H. inaequidentata, which also has almost parallel valve margins.

<p>Sexual activity is a natural-spiritual activity, that means sexual activity is present on earth because of the will of the Creator. Although sexual activity is present because of the will of the Creator, but its activity is determined as yajña or sacrifice, therefore the age of a person may also engage in sexual activity. When, where can someone do it? In addition, the quantity of sexual activity is determined to achieve the quality of sexual activity as yajña or sacred offerings to the Creator.<br />Along with the chaos process as part of the process of destruction of the universe as a recycling of the universe as described in Yuga’s theory; the quality of sexual activity is also increasingly chaotic. In recent years, sexual activity has become a platform for gourmand festivals or an exhibition of genitals or genital tournaments as can be seen on youtube electronic media. Men and women compete with sex forces, this reality will give birth to more and more giant humans, and humans will experience destruction. Therefore the generation of melinial as a digital generation must save itself from the process of destruction from the reality of the negative effects of increasingly chaotic sexual activity.</p>

Rademacher Chaos Complexities for Learning the Kernel Problem

We develop a novel generalization bound for learning the kernel problem. First, we show that the generalization analysis of the kernel learning problem reduces to investigation of the suprema of the Rademacher chaos process of order 2 over candidate kernels, which we refer to as Rademacher chaos complexity. Next, we show how to estimate the empirical Rademacher chaos complexity by well-established metric entropy integrals and pseudo-dimension of the set of candidate kernels. Our new methodology mainly depends on the principal theory of U-processes and entropy integrals. Finally, we establish satisfactory excess generalization bounds and misclassification error rates for learning gaussian kernels and general radial basis kernels.
