Dispersion points and rational curves [PDF]
Proceedings of the American Mathematical Society, 2020 We construct two connected plane sets which can be embedded into rational curves. The first is a biconnected set with a dispersion point. It answers a question of Joachim Grispolakis. The second is indecomposable. Both examples are completely metrizable.

Crystals, 2018 Existing studies on elastic waves in periodically laminated piezoelectric structures mainly concerned the passive band properties, since the electrical boundaries in the considered structures cannot vary.

Ab-initio calculation of phonon dispersion curves: accelerating q point convergence [PDF]
, 2007 We present a scheme for the improved description of the long-range interatomic force constants in a more accurate way than the procedure which is commonly used within plane-wave based density-functional perturbation-theory calculations.

NUMERICAL MODELING OF MODULATING INSTABILITY OF FAST MAGNETO ACOUSTIC WAVES IN MAGNETIC FLUX
Современная наука и инновации, 2022 We study a modulation instability of axi-symmetric fast magnetosonic waves trapped by a cylindrical magnetic flux tube. The plasma motion is described by the ideal magnetohydrodynamic equations in so-called cold plasma approximation where the gas ...

Dynamical properties of Au from tight-binding molecular-dynamics simulations
, 2001 We studied the dynamical properties of Au using our previously developed tight-binding method. Phonon-dispersion and density-of-states curves at T=0 K were determined by computing the dynamical-matrix using a supercell approach. In addition, we performed

Mode Bifurcation and Fold Points of Complex Dispersion Curves for the Metamaterial Goubau Line
, 2009 In this paper the complex dispersion curves of the four lowest-order transverse magnetic modes of a dielectric Goubau line ($\epsilon>0, \mu>0$) are compared with those of a dispersive metamaterial Goubau line.

Photometric Properties of Long-period Variables in the Large Magellanic Cloud [PDF]
, 2002 Approximately four thousand light curves of red variable stars in the LMC were selected from the 2.3-years duration MOA database by a period analysis using the Phase Dispersion Minimization method.

CURVES OF THERMODYNAMIC STATES IN SOME FLUIDS WITH DISPERSION
TASK Quarterly, 2017 Variations in the thermodynamic state of a dispersive medium, caused by sound, are studied. A bubbly liquid and a Maxwell fluid are considered as examples. Curves in the plane of thermodynamic states are plotted.

Control of dispersion in photonic crystal waveguides using group symmetry theory
, 2012 We demonstrate dispersion tailoring by coupling the even and the odd modes in a line-defect photonic crystal waveguide. Coupling is determined ab-initio using group theory analysis, rather than by trial and error optimisation of the design parameters.

Pediatric Blood &Cancer, EarlyView.ABSTRACT Pediatric gastroenteropancreatic neuroendocrine neoplasms (GEP‐NENs) are extremely rare and clinically heterogeneous. Management has largely been extrapolated from adult practice. This European Standard Clinical Practice Guideline (ESCP), developed by the EXPeRT network in collaboration with adult NEN experts, provides (adult) evidence ...
