Obstructive sleep apnea syndrome (OSAS) is characterized with recurrent collapse of upper airway during sleep and results in chronic intermittent hypoxia, which leads to activations of transcriptional factors and critical signaling pathways. HIF-1 is a central component of transcriptional factors involved in hypoxia-induced transcription of specific genes. Our oligo-microarray study showed both...

The reconnection of a trefoil vortex knot is examined numerically to determine how its helicity and two of its vorticity norms behave. During an initial phase, the helicity is remarkably preserved, as reported in recent experiments (Scheeler et al. 2014a). In addition, the enstrophy (Z) has self-similar growth where all √ νZ(t) converge at a viscosity-independent time tx. This effect requires t...

Phaseonium is a three-level Λ quantum system, in which a coherent microwave and an optical control (pump) beams can be used to actively modulate the dielectric response. Here we propose a new metamaterial structure comprising of a periodic array of triangular phaseonium metamolecules arranged as a trefoil. We present a computational study of the spatial distribution of magnetic and electric fie...

This note shows that if two elements of equal trace (e.g., conjugate elements) generate an arithmetic two-bridge knot or link group, then the elements are parabolic. This includes the figure-eight knot and Whitehead link groups. Similarly, if two conjugate elements generate the trefoil knot group, then the elements are peripheral.

Two infinite sequences of minimal surfaces in space are constructed using symmetry analysis. In particular, explicit formulas are obtained for the selfintersecting minimal surface that fills the trefoil knot. UDC 514.763.85, 517.972.6 Introduction. In this paper we consider the Euler–Lagrange minimal surface equation

The COVID-19 pandemic forced changes in the educational response, which involved intensive use of Information and Communication Technology (ICT) skills, among other interventions. circumstances required both families teachers to make an extra effort adapt a reality that was expected last for long time. These had special impact on students with Specific Needs Educational Support (SNES) Special (...
