(particle) is in the same direction or opposite direction as the motion of the wave. Mechanical longitudinal waves have been also referred to as compressional waves or compression waves. Plane pressure wave Examples of non-electromagnetic longitudinal waves include sound waves (alternation in pressure...
Fabrication of resonators whose eigenmodes are linear superpositions of transverse and longitudinal waves has important technological implications. Such modes could be directly pumped electrically through the Fröhlich interaction, providing way toward the realisation of phonon polariton-based mid-infrared emit...
A type of wave is referred to as a longitudinal wave in which particles oscillate or vibrate parallel to the direction in which the wave propagates. For example, ultrasonic waves, sound waves, tsunami waves, etc are some examples of longitudinal waves. The wave generated due to t...
In the center plot, the cohort effects are independent of age, and the longitudinal effects differ by an offset but the effect of aging is identical across cohorts, as seen by the parallel blue lines. In the right plot, the cohort effects depend on age, and in this case also the slope...
Although as a healthcare system we are increasingly starting to systematically assess people for frailty, further research also needs to be done to develop or assess effectiveness of interventions. “Reactive” CGAs have demonstrated an impact on institutionalisation rates, and “proactive” CGA may re...
waves was designed to be 15 months. (b) An example of a participant’s protocol who enrolled at 6.5 years. Measurement content is justified according to the age of each participant. As shown in Supplementary TableS1, the number of psychological behaviour measurements (related to questionnaires...
Clearly other noncardiac factors are also involved. Decreased arterial compliance and ventricular interactions will impair ventricular function (both systolic and diastolic) on exercise. Interestingly, the other derived measurements of global systolic function (end-systolic elastance, stroke work index, and...
It is well known that azobenzene-containing polymers (azopolymers) are sensitive to the polarization orientation of the illuminating radiation, with the resulting photoisomerization inducing material transfer at both the meso- and macroscale. As a result
How long does data collection continue to be classified as longitudinal? A reasonable answer is that longitudinal research normally requires a minimum of three waves of data (Ployhart & Ward, 2011). This can be in a concentrated time period as short as a single semester or spanning a number...
piezoelectric members superposed thereon, coupling elements by which the longitudinally vibratable tuning bars are coupled to each other, supporting elements projecting respectively from the input and output longitudinally vibratable tuning bars, and a holder to which the supporting elements are attached. ...
