Use the correct equation from the Physics Equations Sheet. [2 marks] Energy = J 7 SPECIMEN MATERIAL Turn over 0 3 An electrical circuit is shown in Figure 3. Figure 3 0 3 . 1 The current in the circuit is direct current. What is meant by direct current? [1 mark] Tick...
This chapter is in the style and spirit of a review paper. We point out a number of application of Lie-point symmetries to the study of differential equations arising in different branches of Physics. Obviously, some of the sections of the previous chapter could very well belong here, and ...

A single Incident Report may be completed for multiple students per exam subject per administration (regular or late testing) as long as all of the required information is provided. Include all exam booklets with extra sheets of paper in an Incident Report return envelope (see page 60 of the ...
We emphasize that the intent of this paper is to accurately classify perturbations that destroy or protect the boundary states, where we use the SSH model as one of the examples to illustrate the suitability of the SubSy concept towards this goal. The scenario in which BKLs are involved is ...
In this paper, we focus specifically on equality-type constraints with the objective of minimizing the sum of squared residuals (SSR), and thus it is possible to use the well-known method of Lagrange multipliers. The Karush-Kuhn-Tucker (KKT) stationarity condition yields a system of equations ...
where all the states are collapsed along a straight line. Differently, the CGME approach better captures the StS distribution by modeling the dynamics of multiple clusters of states (27 in Fig.2, namely the CGME27 model). In this work, only the coarse-grained master equations approach will ...
Authors must declare the use of generative AI in scientific writing upon submission of the paper. The following guidance refers only to the writing process, and not to the use of AI tools to analyse and draw insights from data as part of the research process: Generative AI and AI-assisted ...
Despite great progress in simulating multiphysics problems using the numerical discretization of partial differential equations (PDEs), one still cannot seamlessly incorporate noisy data into existing algorithms, mesh generation remains complex, and high-dimensional problems governed by parameterized PDEs cannot...
