We study invertible states of 1D bosonic quantum lattice systems. show that every state is in a trivial phase: after tensoring with some unentangled ancillas, it can be disentangled by fuzzy analog finite-depth circuit. If an has symmetries, may impossible to disentangle way preserves the even adding unentagled ancillas. case finite unitary symmetry G, only obstruction index valued degree-2 cohomology G. two G-invariant are same phase if and their indices coincide.
Although many effective-medium theories have been proposed for studying metamaterials, most of them do not work well multilayer metamaterials with small interlayer distances. Based on rigorous mode-expansion analyses a model system consisting multiple layers subwavelength gratings, we identify that the failures conventional are caused by neglecting strong near-field couplings in homogenizing such systems. These understandings motive us to propose an alternative homogenization approach...
A commonly observed problem of the state-of-the-art natural language technologies, such as Amazon Alexa and Apple Siri, is that their services do not extend to most developing countries' citizens due barriers. Such populations suffer lack available resources in languages build NLP products. This paper presents AllWOZ, a multilingual multi-domain task-oriented customer service dialog dataset covering eight languages: English, Mandarin, Korean, Vietnamese, Hindi, French, Portuguese, Thai....
Abstract Polyurethane elastomers (PUEs) serve a vital role in our daily life and various industrial applications, but their flammability has been proven to be significant drawback. In this work, we have successfully fabricated two modified gallic acids (GAP GAN) by simple esterification, both of which are effective flame retardants cross‐linkers for PUEs. According thermogravimetric analysis (TGA) limiting oxygen index (LOI) tests, the introduction GAP GAN conspicuously improves char yield...
Abstract We study translationally invariant Pauli stabilizer codes with qudits of arbitrary, not necessarily uniform, dimensions. Using homological methods, we define a series invariants called charge modules. describe their properties and physical meaning. The most complete results are obtained for whose modules have Krull dimension zero. This condition is interpreted as mobility excitations. show that it always satisfied translation 2D unique ground state in infinite volume, which was...
Engage is a new form of mobile application that connects students studying English with teachers in real-time via their smartphones. Students receive target language through preparation dialogues, and then apply it to role-play teacher. The conceptualization development follows the user-centred design approach; product was built multiple iterations: first iteration, were invited try out paper mock-up; second tried prototype; external test, fully functional released App Store between October...

We present a coupled mode theory (CMT) to design terahertz flexible band-pass filter. Based on this theory, we designed three filters with passband 0.74-0.89, 0.72-0.91 and 0.72-0.95THz. The transmission in the is all above 80%. This method can be easily extended other frequency regime.
Photovoltaic thermoelectric (PV-TE) is a hot way to expand the range of photoelectric conversion spectra and improve efficiency solar power generation.

We show that Hall conductance and its non-abelian higher-dimensional analogs are obstructions to promoting a symmetry of state gauge symmetry. To do this, we define local Lie algebra over Grothendieck site as pre-cosheaf algebras with additional properties propose should be described by such an object. infinitesimal symmetries gapped quantum spin system form semilinear sets use it construct topological invariants the state.

In recent years, transmissive metasurfaces have provided an effective platform for beam deflection. But the multi-layer meta-atoms used previously are too thick. this paper, we found that certain types of can cover a range phase, therefore suitable application electromagnetic wavefront regulation.
