An effective approach to solving complex problems is to decompose them and integrate dedicated solvers for those subproblems. We introduce a hybrid decomposition that incorporates: (1) a quantum annealer that samples from the configuration space of a relaxed problem to obtain strong candidate solutions, and (2) a classical processor that maintains a global search tree and enforces constraints o...

Abstract. Previously, Bennet and Feynman asked if Heisenberg’s uncertainty principle puts a limitation on a quantum computer (Quantum Mechanical Computers, Richard P. Feynman, Foundations of Physics, Vol. 16, No. 6, p597-531, 1986). Feynman’s answer was negative. In this paper, we will revisit the same question for the discrete time Fourier transform uncertainty principle. We will show that the...

We tackle the crucial challenge of fusing different modalities features for multimodal sentiment analysis. Mainly based on neural networks, existing approaches largely model interactions in an implicit and hard-to-understand manner. address this limitation with inspirations from quantum theory, which contains principled methods modeling complicated correlations. In our quantum-inspired framewor...

In this paper, we investigate variation of the wavelength, intensity and polarization of the self-assembled InAs/GaAs quantum dots emission by microphotoluminescence spectroscopy at the liquid helium temperature. The microcavity wafer sample is grown by molecular beam epitaxy (MBE) and chemically etched into the micropillar structure (with elliptical cross section - long and short axis 2µm×1.5µ...

OBJECTIVES The current Recommended Dietary Allowance (RDA) for protein is based on short-term nitrogen balance studies in young adults and may underestimate the amount needed to optimally preserve physical function in older adults. We examined the association between protein intake and the onset of mobility limitation over 6 years of follow-up in older adults in the Health ABC study. DESIGN P...

For people with disabilities the Web holds great chances for transforming former barriers to information access, communication and participation at work and in social life. The research question underlying the described project is: What potentials do the Web and the latest Internet-technologies offer to students with extensive mobility limitations in terms of staying in touch with other people ...

Recent evidence suggests that music-based movement (MbM) therapy may be a promising intervention to improve gait and gait-related activities in Parkinson's disease (PD) patients, because it naturally combines cognitive movement strategies, cueing techniques, balance exercises and physical activity while focussing on the enjoyment of moving on music instead of the current mobility limitations of...

The electronic transport in an infinite arrays of driven quantum wells coupled to a quantum ring is studied via a single-band tunneling tight-biding Hamiltonian by perturbing and numerical simulations approaches. In the perturbing approach, an analytical relationship in terms of the coupling constants between nearest-neighbors in quantum wire coupled to a ring based on the quantum dynamical alg...

  Because the key issue in quantum information and quantum computing is entanglement, the investigation of the effects of environment, as a source of quantum dissipation, and interaction between environment and system on entanglement and quantum phase transition is important. In this paper, we consider two-qubit system in the anisotropic Heisenberg XXZ model with the Dzyaloshinskii-moriya inter...
