Fast and optimal transport of atoms with non-harmonic traps [PDF]
Phys. Rev. A 92, 043410 (2015), 2015 We investigate the fast transport of an atom or a packet of atoms by different kinds of non-harmonic traps including power-law traps. The study is based on the reverse engineering method. Exact results are obtained and applied to design robust transport protocols.

Insights into transport mechanism from LeuT engineered to transport tryptophan [PDF]
The EMBO Journal, 2011 LeuT is a bacterial homologue of the neurotransmitter:sodium symporter (NSS) family and, being the only NSS member to have been structurally characterized by X-ray crystallography, is a model protein for studying transporter structure and mechanism. Transport activity in LeuT was hypothesized to require structural transitions between open-to-out and ...

Optimization of Assignment of Rapid Train Stops: Example of the JR Nambu Line
Journal of Advanced Mechanical Design, Systems, and Manufacturing, 2012 On many railway lines, not only local trains but also rapid trains are operated. Operating rapid trains can improve the convenience of the passengers, but that outcome strongly depends on the assignment of rapid train stops, the associated timetable, and

Stacking and interlayer electron transport in MoS2 [PDF]
Physical Review B 98, 115403 (2018), 2018 In this work, we investigate the effect of the stacking sequence in MoS2 multilayer systems on their electron transport properties, through first-principles simulations of structural and electron transport properties. We show that interlayer electron transport is highly sensitive to the stacking sequence of the multilayers, with specific sequences ...

'Resilience thinking' in transport planning [PDF]
, 2015 Resilience has been discussed in ecology for over forty years. While some aspects of resilience have received attention in transport planning, there is no unified definition of resilience in transportation. To define resilience in transportation, I trace
