Recently, higher-order topological insulators (HOTIs) have been introduced, and were shown to host topological corner states under the theoretical framework of Benalcazar-Bernevig-Hughes. Here we unveil some topological effects in HOTIs by studying the t
Incrementally learning new information from a non-stationary stream of data, referred to as ‘continual learning’, is a key feature of natural intelligence, but a challenging problem for deep neural networks. In recent years, numerous deep learning meth

The state-space$S$depends on the state size of the memory model. In the DSR, there are merely two state variables, thus the state can be formulated as$s = (D, S)$. The action space$\mathcal{A} = {\Delta t_1, \Delta t_2, \ldots, \Delta t_n }$cons...
The sub-structures are arranged in a hierarchy such that an embedded symbol can be perceived as relating to the local features. These features are, in turn perceived as relating to the local structure which then relates to the entire structure. In this way, isolated symbols can be located in...
I had the same math teacher for both 7th and 9th grade. He always wore a belt with the Jewish Chai symbol on the buckle. Why he felt the need to call so much attention to his religious convictions via a buckle above his crotch is beyond me, but because of that belt, I have never...

The symbol \(m\) denotes the ordinal number of the DMD pattern, \( m = 1,2,3 \ldots {\text{M}}\). CCD pixel collects the measured value \(Y_{x,y} (m)\) when DMD provides the \(m\) th pattern, i.e., DMD camera captures M images after M times exposure. Assuming that...
