Isotopy classes for 3-periodic net embeddings

Entangled embedded periodic nets and crystal frameworks are defined, along with their dimension type, homogeneity type, adjacency depth and periodic isotopy type. Periodic isotopy classifications are obtained for various families of embedded nets with small quotient graphs. The 25 periodic isotopy classes of depth-1 embedded nets with a single-vertex quotient graph are enumerated. Additionally, a classification is given of embeddings of n-fold copies of pcu with all connected components in a parallel orientation and n vertices in a repeat unit, as well as demonstrations of their maximal symmetry periodic isotopes. The methodology of linear graph knots on the flat 3-torus [0,1)3 is introduced. These graph knots, with linear edges, are spatial embeddings of the labelled quotient graphs of an embedded net which are associated with its periodicity bases.

Approximate Two-Sphere One-Cylinder Inequality in Parabolic Periodic Homogenization. (arXiv:2005.00989v2 [math.AP] UPDATED)

In this paper, for a family of second-order parabolic equation with rapidly oscillating and time-dependent periodic coefficients, we are interested in an approximate two-sphere one-cylinder inequality for these solutions in parabolic periodic homogenization, which implies an approximate quantitative propagation of smallness. The proof relies on the asymptotic behavior of fundamental solutions and the Lagrange interpolation technique.

Algorithmic Averaging for Studying Periodic Orbits of Planar Differential Systems. (arXiv:2005.03487v1 [cs.SC])

One of the main open problems in the qualitative theory of real planar differential systems is the study of limit cycles. In this article, we present an algorithmic approach for detecting how many limit cycles can bifurcate from the periodic orbits of a given polynomial differential center when it is perturbed inside a class of polynomial differential systems via the averaging method. We propose four symbolic algorithms to implement the averaging method. The first algorithm is based on the change of polar coordinates that allows one to transform a considered differential system to the normal form of averaging. The second algorithm is used to derive the solutions of certain differential systems associated to the unperturbed term of the normal of averaging. The third algorithm exploits the partial Bell polynomials and allows one to compute the integral formula of the averaged functions at any order. The last algorithm is based on the aforementioned algorithms and determines the exact expressions of the averaged functions for the considered differential systems. The implementation of our algorithms is discussed and evaluated using several examples. The experimental results have extended the existing relevant results for certain classes of differential systems.

METHOD TO IDENTIFY AN APPROACH FOR ACHIEVING MAMMALIAN FERTILIZATION AND TIME PERIOD FOR INSEMINATION

The diagnosis of male infertility is based predominantly on the results of standard semen analysis for concentration, total motility, progressive motility, volume, pH, viscosity and/or morphology. When sperm enter the female reproductive tract, they must undergo a series of physiological changes, known as capacitation, in order to fertilize an egg. This process involves plasma membrane changes that occur in response to stimuli within the female tract. These changes include removal of sterols and redistribution of the ganglioside GM1. Semen analysis identifies only half the cases of male infertility due to standard semen analysis providing little information on sperm functional competence. Previous data demonstrated that localization of the ganglioside, GM1, identifies sub-populations of sperm capable of undergoing the functional maturation process known as capacitation and tracks strongly with fertility.
