Molding the wavefront of acoustic waves into the desired shape is of paramount significance in acoustics, which however are usually constrained by the acoustical response of naturally available materials. The emergence of acoustic metamaterials built by

Homework Statement The Attempt at a Solution Do note I switched up the i, j and k vectors. I am getting half the answer correct. -7.2 is correct according to the answer key but my other solution -3.24 is clearly wrong. Does anyone know what I did wrong? I tried to be neat as......
These so-called “standard candles” include type 1a supernovae – which are basically exploded white-dwarf stars that have a certain critical mass. Now, let’s fast-forward to 2013. By analysing maps of the Cosmic Microwave Background from the Planck mission, astronomers were able to ...
area A area 1A 2 S R The area of the cross-section of the wire changes from A at R to 1 A at S. 2 There is a constant current in the wire. Charge Q passes R in time t. What is the charge passing point S in the same time t ? A 1 Q B Q C Q 2 D 2 Q 2 34 Four...
more matter than we can observe. Scientists since the 1960s and ’70s have been trying to figure out what this mysterious substance is, using ever-more complicated technology. However, a growing number of physicists suspect that the answer may be that there is no such thing asdark matterat ...
(1a) and a reverse (ab). These interactive illustrated cards (1) are variable in shape and size, but share essential characteristics, namely, having at least one of their faces suitable for supporting various graphics. In this example, the obverse (1a) is the support of a graphic ...

In this study, we develop physics-informed neural networks (PINNs) to solve an isothermal fixed-bed (IFB) model for catalytic CO2 methanation. The PINN includes a feed-forward artificial neural network (FF-ANN) and physics-informed constraints, such as g
(Fig.1a)5,7. As an alternative to this deterministic bottom-up construction, the top-down design presented here relies on the capability to harness large, complex, intermodal mode mixersUjof dimensionn\(({U}_{j}\in {{{\mathcal{U}}}({{{\bf{n}}}))\)and reconfigurable phase plane...
