Oxygen vacancies in perovskite oxides are of great interest both from fundamental viewpoint due to their effect on electronic and magnetic properties of oxides – and from applications viewpoint due to their importance for solid oxide fuel cells. In the latter case, understanding the dynamic behavior of vacancies is crucial. Oxygen vacancy (Vo) ordering can substantially affect local structure a...

In this letter, a pilot structure and an efficient algorithm for downlink synchronization and cell searching in OFDM-based cellular systems are proposed. The pilots, randomly allocated in the frequency domain, allow us to minimize inter-cell interference (ICI) as well as to increase cell searching capability, estimation range of integer carrier frequency offset (CFO), and estimation accuracy of...

Droplet solitons are coherently precessing solitary waves that have been recently realized in thin ferromagnets with perpendicular anisotropy. In the strongly nonlinear regime, droplets can be well approximated by a slowly precessing, circular domain wall with a hyperbolic tangent form. Utilizing this representation, this work develops a general droplet modulation theory and applies it to study...

Although both LaAlO3 (LAO) and SrTiO3 (STO) are insulators, at the interface of LAO/STO [001] stacking structures, formation of two-dimensional electronic gas with high mobility was reported [1]. Associated with this, a problem concerning divergence of electrostatic potential was also pointed out [2]. We performed first-principles calculations on LAO/STO [001] stacking thin films and investigat...

PARIS (Personal Archiving and Retrieving Image System) is an experiment personal photograph library, which includes more than 80,000 of consumer photographs accumulated within a duration of approximately five years, metadata based on our proposed MPEG-7 annotation architecture, Dozen Dimensional Digital Content (DDDC), and a relational database structure. The DDDC architecture is specially desi...

INtrODUctION As companies begin to develop competence in managing internal knowledge and applying it towards achieving organizational goals, they are setting their sights on new sources of knowledge that are not necessarily found within the boundaries of the firm. Customer knowledge management comprises the processes that are concerned with the identification, acquisition, and utilization of kn...

Article history: Received 11 December 2015 Received in revised form 4 May 2016 Accepted 11 May 2016 Available online 24 May 2016 Epitaxial LiCoO2 (LCO) thin films of different orientations were fabricated by pulsed laser deposition (PLD) in order to model single-crystal behavior of intercalation cathodes during electrochemical reactions. This paper demonstrates that (1) epitaxial growth of LCO ...
