Berry Phase of a Resonant State

We derive closed analytical expressions for the complex Berry phase of an open quantum system in a state which is a superposition of resonant states and evolves irreversibly due to the spontaneous decay of the metastable states. The codimension of an accidental degeneracy of resonances and the geometry of the energy hypersurfaces close to a crossing of resonances differ significantly from those of bound states. We discuss some of the consequences of these differences for the geometric phase factors, such as: Instead of a diabolical point singularity there is a continuous closed line of singularities formally equivalent to a continuous distribution of `magnetic' charge on a diabolical circle; different classes of topologically inequivalent non-trivial closed paths in parameter space, the topological invariant associated to the sum of the geometric phases, dilations of the wave function due to the imaginary part of the Berry phase and others.Comment: 28 pages Latex, three uuencoded postcript figure

MobilityMirror: Bias-Adjusted Transportation Datasets

We describe customized synthetic datasets for publishing mobility data. Private companies are providing new transportation modalities, and their data is of high value for integrative transportation research, policy enforcement, and public accountability. However, these companies are disincentivized from sharing data not only to protect the privacy of individuals (drivers and/or passengers), but also to protect their own competitive advantage. Moreover, demographic biases arising from how the services are delivered may be amplified if released data is used in other contexts. We describe a model and algorithm for releasing origin-destination histograms that removes selected biases in the data using causality-based methods. We compute the origin-destination histogram of the original dataset then adjust the counts to remove undesirable causal relationships that can lead to discrimination or violate contractual obligations with data owners. We evaluate the utility of the algorithm on real data from a dockless bike share program in Seattle and taxi data in New York, and show that these adjusted transportation datasets can retain utility while removing bias in the underlying data.Comment: Presented at BIDU 2018 workshop and published in Springer Communications in Computer and Information Science vol 92

Dynamic behavior analysis via structured rank minimization

Human behavior and affect is inherently a dynamic phenomenon involving temporal evolution of patterns manifested through a multiplicity of non-verbal behavioral cues including facial expressions, body postures and gestures, and vocal outbursts. A natural assumption for human behavior modeling is that a continuous-time characterization of behavior is the output of a linear time-invariant system when behavioral cues act as the input (e.g., continuous rather than discrete annotations of dimensional affect). Here we study the learning of such dynamical system under real-world conditions, namely in the presence of noisy behavioral cues descriptors and possibly unreliable annotations by employing structured rank minimization. To this end, a novel structured rank minimization method and its scalable variant are proposed. The generalizability of the proposed framework is demonstrated by conducting experiments on 3 distinct dynamic behavior analysis tasks, namely (i) conflict intensity prediction, (ii) prediction of valence and arousal, and (iii) tracklet matching. The attained results outperform those achieved by other state-of-the-art methods for these tasks and, hence, evidence the robustness and effectiveness of the proposed approach

I know people who can and who cannot: A measure of the perception of economic inequality in everyday life

Versión preprintThis paper describes the development of the Perceived Economic Inequality in Everyday Life (PEIEL) scale. It is written and validated in Spanish. We first carried out an exploratory study, using a sample of 205 participants (52.2% men and 47.8% women; age: M = 24.69, SD = 8.95). We then conducted a confirmatory study with a sample size of 215 individuals (43.7% men and 56.3% women; age: M = 23.83, SD = 6.46). Results showed that the PEIEL scale is a valid and reliable unidimensional instrument. This scale negatively predicted tolerance of economic inequality over and above perceived inequality measured by wage gap estimates. In addition, perceived economic inequality in everyday life was negatively associated with tolerance of inequality, particularly in individuals with right-wing political ideology.Universidad de Costa Rica/[OAICE-006-2017]/UCR/Costa RicaUCR::Sedes Regionales::Sede de Occident

The analysis of wood harvesting restrictions in conservation areas and old-growth forests of the Arkhangelsk oblast

An earlier analysis published in 2007 as Working Papers of the Finnish Forest Research Institute 56Analysis of the current state and wood harvesting restrictions in officially existing and planned conservation areas as well as unofficial intact forest landscapes of the Arkhangelsk oblast is provided in this report. Intact forest landscapes are suggested by NGOs and these forests do not have wood harvesting restrictions according to the Russian legislation. However, environmentally responsible forest industry companies have voluntarily agreed not to procure wood from these forests.In the beginning April 2008, Arkhangelsk oblast has 106 official conservation areas with a total area of 6.5 million ha. However, several reserves, such as the large reserve Frants-Iosif Land located in Baretsevo sea islands, are out of forest fund of Arkhangelsk oblast. The total area of the forest-related conservation areas is 2.2 million ha (7.6% of the total forest fund of Arkhangelsk oblast). All types of fellings are prohibited in 11 official conservation areas (0.6 million ha or 2.1% of the forest fund of Arkhangelsk oblast). Final fellings (or clearcut) are prohibited in 51 official conservation areas (1.6 million ha or 5.4% of the forest fund of Arkhangelsk oblast). The rest of the conservation areas (28600 ha or 0.1% of the forest fund of Arkhangelsk oblast) have no restrictions for wood harvesting, but clearcut is forbidden according to current Forest Code. Two officially planned conservation areas (5.3 million ha) have been clearly recognized; however only the Onezhskoye Pomorye national park (180400 ha or 0.6% of the forest fund of Arkhangelsk oblast) is located within forest fund of the region and has restrictions for wood harvesting. NGOs have suggested 11 separate areas of intact forest landscapes (approximately 9.5 million ha or 32.4% of the forest fund of Arkhangelsk oblast). The major areas of intact forest landscapes are located in Leshukonsky, Mezensky, Severodvinsky, Onezhsky, Karpogorsky, Krasnoborsky, Pinezhsky, Priozerny, Sursky, Vyisky and Bereznikovsky leskhozes. Locations of conservation areas and intact forest landscapes are shown in the whole Arkhangelsk oblast, at forest district ( leskhoz ) and at forest block ( kvartal ) levels in this report
