Modulation techniques for data superposition on amplitude-modulated signals [PDF]
, 1983 Double-sideband amplitude-modulation is widely used because of its simplicity in transmission and reception, but in a number of applications the inclusion of a data channel has become an additional requirement.

Time-delay-induced amplitude death in chaotic map lattices and its avoiding control
, 2007 The present Letter deals with amplitude death in chaotic map lattices coupled with a diffusive delay connection. It is shown that if a fixed point of the individual map satisfies an odd-number property, then amplitude death never occurs at the fixed ...

Enhanced Strength and Corrosion Resistance of Ti‐13Nb‐12Ta‐10Zr‐4Sn Alloy by Aging Treatment
Advanced Engineering Materials, EarlyView.This work systematically investigates the effect of aging treatment on mechanical properties and corrosion behavior of vacuum arc‐melted Ti‐13Nb‐12Ta‐10Zr‐4Sn alloy. Owing to the increased α″ martensite, strength and corrosion resistance were significantly enhanced by aging treatment.

Why variable amplitude loading? A key for lightweight-structural durability design
, 2022 7380The technical importance of variable amplitude (spectrum) loading is not only given by obtaining much longer fatigue lives compared with those determined under constant amplitude loading with the maximum value of the spectrum.

DDF amplitudes are lightcone amplitudes and the naturalness of Mandelstam maps
The European Physical Journal CAbstract We show that on-shell DDF amplitudes are on-shell lightcone amplitudes and that Mandelstam maps emerge naturally with a precise normalization, and are intrinsic to the DDF states. Off-shell DDF and Mandelstam amplitudes à la Kaku–Kikkawa differ.

Advanced Engineering Materials, EarlyView.Scandium (Sc)‐doped AlCoCrFeMo HEA coatings are fabricated via flame spraying with 0.1, 0.3, and 0.5 wt% Sc additions. Among these, the HEA‐Sc0.3 coating exhibits the highest corrosion resistance, indicated by a more positive corrosion potential and lower current density.

The modulation of alpha-wave amplitude in human EEG by the intention to act with a motor response
, 2009 The most conspicuous signal in the human EEG is the so-called alpha wave, oscillations in the frequency range of 8 to 12 Hz. Visual stimulation of the retina suppresses the amplitude of alpha waves (Berger effect), and increased attention can reduce them.

Advanced Engineering Materials, EarlyView.This study shows that superalloys used in aircraft engine disks become much more prone to deformation at high temperatures if they have been strained during manufacturing. This effect increases with the level of prior strain but eventually reaches a limit.
