(AIP Publishing, 2021-03-14)This Perspective reviews the fundamental physics of space–charge interactions that are important in various media: vacuum gap, air gap, liquids, and solids including quantum materials. It outlines the critical and recent developments since a previous ... -
(Informa UK Limited, 2017-09-14)The evidence for connections between subjective well-being and spatial factors remains inconclusive, especially with respect to the immediate living environment. To fill this gap, this paper explores the relationship between individual-level subjective ...
-
(MDPI AG, 2016-06-03)Particulate matter mass concentrations and size fractions of PM1, PM2.5, PM4, PM10, and PM15 measured in transversal horizontal profile of two dust storms in southwestern Iceland are presented. Images from a camera network were used to estimate the ...
-
(MDPI AG, 2020-04-16)We propose an unmixing framework for enhancing endmember fraction maps using a combination of spectral and visible images. The new method, data fusion through spatial information-aided learning (DFuSIAL), is based on a learning process for the fusion ...
-
(MDPI AG, 2019-08-14)In this article, a novel approach for land cover change detection (LCCD) using very high resolution (VHR) remote sensing images based on spatial-spectral feature fusion and multi-scale segmentation voting decision is proposed. Unlike other traditional ...
-
(MDPI AG, 2018-11-27)This article summarized the spatiotemporal pattern of land use/land cover (LU/LC) and urban heat island (UHI) dynamics in the Metropolitan city of Tehran between 1988 and 2018. The study showed dynamics of each LU/LC class and their role in influencing ...
-
(Wiley, 2019-06)Ecosystem engineers can have diverse and conflicting effects on their ecosystems, and the balance between these effects can depend on the physical environment. This context dependence means that environmental variation can produce large differences in ...
-
(University of Iceland, School of Engineering and Natural Sciences, Faculty of Physical Sciences, 2019-08)The purpose of this thesis is to develop spatio-temporal statistical models for glaciology, using the Bayesian hierarchical framework. Specifically, the process level is modeled as a time series of computer simulator outputs (i.e., from a numerical ...
-
(University of Iceland, School of Humanities, Faculty of Icelandic and Comparative Cultural Studies, 2021)The thesis examines what I term spectral memories in Icelandic culture and focuses on the interplay between memory, identity and the haunted imagination in contemporary literary texts and visual works of art. I employ the term “spectral” to define ...
-
(Informa UK Limited, 2018-01)Managing transmission and storage of hyperspectral (HS) images can be extremely difficult. Thus, the dimensionality reduction of HS data becomes necessary. Among several dimensionality reduction techniques, transform-based have found to be effective ...
-
(Multidisciplinary Digital Publishing Institute, 2016)This paper introduces a new supervised classification method for hyperspectral images that combines spectral and spatial information. A support vector machine (SVM) classifier, integrated with a subspace projection method to address the problems of ...
-
(IEEE, 2014)Hyperspectral remote sensing technology allows one to acquire a sequence of possibly hundreds of contiguous spectral images from ultraviolet to infrared. Conventional spectral classifiers treat hyperspectral images as a list of spectral measurements ...
-
(International Research and Cooperation Association for Bio & Socio-Sciences Advancement (IRCA-BSSA), 2018-08-31)Abstract Interaction of riociguat with human serum albumin (HSA) is extremely important in understanding the drug's disposition and efficiency. In the current study, the binding of riociguat to HSA was explored using spectroscopic methods and molecular ...
-
(Oxford University Press (OUP), 2018-07-25)STUDY QUESTION: Does chemotherapy exposure (with or without alkylating agents) or primary diagnosis affect spermatogonial quantity in human prepubertal testicular tissue? SUMMARY ANSWER: Spermatogonial quantity is significantly reduced in testes of ...
-
(American Chemical Society (ACS), 2018-11-12)We report stable orthogonally polarized domains in high-density polariton solitons propagating in a semiconductor microcavity wire. This effect arises from spin-dependent polariton–polariton interactions and pump-induced imbalance of polariton spin ...
-
(Springer Nature, 2016-11-14)Recent experimental data demonstrate emerging magnetic order in platinum atomically thin nanowires. Furthermore, an unusual form of magnetic anisotropy – colossal magnetic anisotropy (CMA) – was earlier predicted to exist in atomically thin platinum ...
-
(American Physical Society (APS), 2016-02-09)We demonstrate that a spin-dependent Seebeck effect can be detected in quantum wells with zinc-blend structure with equal Rashba-Dresselhaus spin-orbit couplings. This theory is based on the establishment of an itinerant antiferromagnetic state, a low ...

(Springer Nature, 2016-12-07)Horses have been valued for their diversity of coat colour since prehistoric times; this is especially the case since their domestication in the Caspian steppe in ~3,500 BC. Although we can assume that human preferences were not constant, we have only ...
-
(American Physical Society (APS), 2019-04-26)The two-dimensional Heisenberg exchange model with out-of-plane anisotropy and a Dzyaloshinskii-Moriya interaction is employed to investigate the lifetime and stability of antiferromagnetic (AFM) skyrmion as a function of temperature and external ...
