Coherently displaced oscillator quantum states of a single trapped atom [PDF]
Quantum Sci. Technol. 4, 024010 (2019), 2018 Coherently displaced harmonic oscillator number states of a harmonically bound ion can be coupled to two internal states of the ion by a laser-induced motional sideband interaction. The internal states can subsequently be read out in a projective measurement via state-dependent fluorescence, with near-unit fidelity.

Mapping the energy surface of PbTiO3 in multidimensional electric-displacement space [PDF]
Phys. Rev. B 84, 115107 (2011), 2011 In recent years, methods have been developed that allow first-principles electronic-structure calculations to be carried out under conditions of fixed electric field. For some purposes, however, it is more convenient to work at fixed electric displacement field.

Coexistence of polar displacements and conduction in doped ferroelectrics: an ab initio comparative study [PDF]
Physical Review Materials, 3(5), 054405 (2019), 2019 Polar metals are rare because free carriers in metals screen electrostatic potential and eliminate internal dipoles. Degenerate doped ferroelectrics may create an approximate polar metallic phase. We use first-principles calculations to investigate $n$-doped LiNbO$_3$-type oxides (LiNbO$_3$ as the prototype) and compare to widely studied perovskite ...

Minimum Displacement Motion Planning for Movable Obstacles [PDF]
arXiv, 2022 This paper presents a minimum displacement motion planning problem wherein obstacles are displaced by a minimum amount to find a feasible path. We define a metric for robot-obstacle intersection that measures the extent of the intersection and use this to penalize robot-obstacle overlaps.

Internally Displaced Persons (IDPs) [PDF]
, 2021 Internally Displaced Persons (‘IDPs’) are described by the United Nations Guiding Principles on Internal Displacement as persons or groups of persons who have been forced or obliged to flee or to leave their homes or places of habitual residence, in particular as a result of or in order to avoid the effects of armed conflict, situations of generalized ...

Expression and Localization of aquaporin‐1 in Temporomandibular Joint Disc with Internal Derangement [PDF]
, 2012 Background: Internal derangement is the most frequent arthropathy affecting the temporomandibular joint, where its commonest form is anterior disc displacement with or without reduction.

International Journal of Adaptive Control and Signal Processing, EarlyView., 2023 Summary In this contribution, we propose a detailed study of interpolation‐based data‐driven methods that are of relevance in the model reduction and also in the systems and control communities. The data are given by samples of the transfer function of the underlying (unknown) model, that is, we analyze frequency‐response data.

Displacement field estimation from OCT images utilizing speckle information with applications in quantitative elastography [PDF]
, 2020 In this paper, we consider the problem of estimating the internal displacement field of an object which is being subjected to a deformation, from Optical Coherence Tomography (OCT) images before and after compression. For the estimation of the internal displacement field we propose a novel algorithm, which utilizes particular speckle information to ...

Groningen Journal of International Law, 2017 It is well known that Colombia is the country with the highest number of internally displaced people (IDP) in the world. Almost 7.5 million people have been forced to leave their homes for reasons related to the internal armed conflict, which lasted for ...
