where{W}_{{{\rm{T}}}\sim {\nu }^{-\alpha }is the energy density of the excited (slow) propagating mode. The exponent\alphadictates the formation of the cusp in Eq. (1) and its value is controlled by the incident wave via wavefront shaping techniques37,38,39,40. Here, we propo...
In such cases, the increased amplification at higher frequencies introduces distortion from undesired frequencies which may be either harmonics of the desired signal or signals caused by amplitude modulation of the echo by irregularities of the terrain as the airplane flies therealong. It is consequentl...
As the FSK rate increases, the input power goes to zero for the without DAM case as the crystal does not build up to full resonance at either frequency. The impedance slightly increases for the DAM case versus increasing FSK rate, and the input average power slightly decreases. However, the...
The stability of textural properties, which are evaluated as viscosity, firmness, amplitude sweep, adhesiveness, gumminess, springiness, and cohesiveness among others, is the main indicator of yogurt rheological properties (Guven et al., 2005). Texture stability is influenced by TS, contents of fat...
What happens to the amplitude of the signal detected by Q? A decreases steadily B increases and decreases regularly C increases steadily D remains constant 24 The siren of a moving police car emits a sound wave with a frequency of 440 Hz. A stationary observer hears sound of frequency 494 ...
Leaf phosphorous concentration decreases more (PI = -1.8; Poorter et al. 2019) than the leaf nitrogen concentration, and hence the N/P ratio of the leaves increases with increasing DLI (Fig. 5e, PI = 1.3), be it with a low consistency. This mirrors the effect of [CO2], ...
It is worth reviewing that the main constituents of living organisms, especially proteins, are just six elements: (i) oxygen; the strongest oxidizing agent; (ii) hydrogen; the strongest reducing agent; and (iii) the four elements that have the largest amplitude in redox numbers: carbon (−...
(e)shows the Nyquist plot obtained at the frequency range from 100 kHz to 0.1 Hz with different amplitude of single sin wave (0.005, 0.01, 0.015, and 0.02 V RMS value). The calculated internal resistance (Rs) for MoS2-3D graphene hybrid is 18.66 ohm. The corresponding ...
The presence of the thermal safety system has no measurable effect on the key features of the data, such as chest movement amplitude and signal-to-noise ratio (SNR) (Supplementary Fig. 20). Figure 5a shows the action of the thermal safety system that follows shorting of the actual battery ...
