On the principle of limiting amplitude
and the Sommerfeld radiation conditions at infinity. A denotes the Laplacian in E and o* is a real number. In the case when &(#)=0 and the real valued function £(#) is once continuously differentiable and its support is compact, this principle has been proved by O. A. Ladyzenskaja [1] . Here the rate of approach to steady state is like e~, e>0 as £-^oo.

The amplitudes of nonlinear oscillations
The authors consider the nonlinear second-order differential equation \[ y''(t)+p(t)f(y(t))=0, ~t\geq t_0, \] where \(p\) is continuous and positive, and \(f\) is continuous with \[ uf(u)>0\text{ for } u\neq 0 \] and \[ \int_0^{\pm\infty}f(u)\,du=\infty.

The share of technical thermoplastics is expected to grow further in the e‐mobility segment. In this study, a detailed temperature‐based tribological characterization of technical thermoplastics is performed. The tribological properties are discussed in terms of the dynamic mechanical properties of polymers at different ambient temperatures. A proof of

Amplitude death in coupled chaotic oscillators
Amplitude death can occur in chaotic dynamical systems with time-delay coupling, similar to the case of coupled limit cycles. The coupling leads to stabilization of fixed points of the subsystems.

ON THE PROPAGATION OF ION ACOUSTIC SOLITARY WAVES OF SMALL AMPLITUDE.
: It is shown that under certain approximations the basic system of equations governing the propagation of ion acoustic waves can be reduced to the Kortweg-deVries equation. (Author)

Periodic submicron features are fabricated on 304 stainless steel using single and double femtosecond laser pulses. By adjusting polarization, fluence, and inter‐pulse delay, 1D and 2D nanostructures are formed. Enhanced hydrophobicity and dense surface‐enhanced Raman spectroscopy hotspots enable analyte detection down to 10−10 M with good ...

Face amplitude of spinfoam quantum gravity
The structure of the boundary Hilbert-space and the condition that amplitudes behave appropriately under compositions determine the face amplitude of a spinfoam theory. In quantum gravity the face amplitude turns out to be simpler than originally thought.

I. On the results of an examination of the orientation of a number of Greek temples, with a view to connect these angles with the amplitudes of certain stars at the time these temples were founded, and an endeavour to derive therefrom the dates of their foundation by consideration of the changes produced upon the right ascension and declination of the stars arising from the precession of the equinoxes [PDF]

Primary phases and a fatigue crack are studied in a forged blank of an aluminum alloy using synchrotron and laboratory X‐ray computed tomography. To image the crack, the fatigue test is interrupted, and a static tensile load is applied to open the crack.
