Published in 2018 at "Quantum Information Processing"

DOI: 10.1007/s11128-018-2063-y

Abstract: Reference-frame-independent quantum key distribution (RFI-QKD) can generate secure keys even when the reference frames drift slowly. Here, we propose to realize RFI-QKD with the single-photon-added coherent source (SPACS). Simulation results show that compared with the… read more here.

Published in 2017 at "International Journal of Fuzzy Systems"

DOI: 10.1007/s40815-017-0361-7

Abstract: Multi-level association rule mining techniques that are developed for mining data at multiple-level taxonomy usually rely on minimum support and minimum confidence threshold for extracting frequent items at various levels. But the usage of above… read more here.

Published in 2020 at "Advances in colloid and interface science"

DOI: 10.1016/j.cis.2020.102212

Abstract: In this paper first a generally valid model is derived from the two fundamental equations of Gibbs for temperature and composition dependences of all types of interfacial energies. This general model is applied here to… read more here.

Published in 2021 at "Optik"

DOI: 10.1016/j.ijleo.2021.167672

Abstract: Abstract Collective phenomena in the Tavis–Cummings model has been widely studied, focusing on the phase transition features. On many occasions, it has been used variational approaches that consider separated radiation-matter systems. This paper examines the… read more here.

Published in 2019 at "Journal of experimental child psychology"

DOI: 10.1016/j.jecp.2019.104707

Abstract: This long-term follow-up of an early childhood training study (Growing Memories) to promote elaborative reminiscing tested continued effects on mother-child reminiscing and on adolescents' narrative coherence. Of the original 115 families, 100 participated when their… read more here.

Published in 2019 at "Materialia"

DOI: 10.1016/j.mtla.2019.100225

Abstract: Abstract Pinning effect of second-phase particles has been demonstrated as an extremely effective way to impede grain boundary (GB) migration to increase strength or thermal stability, particularly for nano-scale materials. Previous studies on the particle… read more here.

Published in 2017 at "Optics Communications"

DOI: 10.1016/j.optcom.2017.01.022

Abstract: Abstract Generalized few-mode-fiber (FMF) transmission uses N coherent receivers for mode detection, where N scales with the number of fiber modes. Multiple coherent receivers increase the cost of optical network units (ONUs) in access networks,… read more here.
