Approximate fourier domain expression for bloch-siegert shift
(John Wiley and Sons Inc., 2015)Purpose: In this study, a newsimple Fourier domain-based analytical expression for the Bloch-Siegert (BS) shift-based B1 mapping method is proposed to obtain |B1+| more accurately while using short BS pulse durations and ... -

Charged bosons in a quasi-one-dimensional system
(American Physical Society, 2000)The ground-state properties of a system of charged bosons in a quasi-one-dimensional model with a neutralizing background are investigated within the hypernetted-chain approximation. Strong correlation effects drive the ... -
Circuit partitioning using mean field annealing
(Elsevier, 1995)Mean field annealing (MFA) algorithm, proposed for solving combinatorial optimization problems, combines the characteristics of neural networks and simulated annealing. Previous works on MFA resulted with successful mapping ... -
Context and theorizing in the global south: challenges and opportunities for an international dialogue
(ANPAD - Associacao Nacional de Pos-Graduacao e Pesquisa em Administracao, 2019)Brazilian researchers have been encouraged to internationalize their research, expanding their insertions into high impact international journals. This task in turn demands thinking outside the commonly used Eurocentric ... -
Density profile of a Bose-Einstein condensate inside a pancake-shaped trap: Observational consequences of the dimensional cross-over in the scattering properties
(Elsevier Science B.V., 2002)It is theoretically well known that two-dimensionality of the scattering events in a Bose-Einstein condensate introduces a logarithmic dependence on density in the coupling constant entering a mean-field theory of the ... -
Dynamic correlation effects on the plasmon dispersion in a two-dimensional electron gas
(The American Physical Society, 2003)The charge-density oscillations (plasmons) of a low-density two-dimensional uniform electron gas are studied within the framework of finite temperature and frequency dependent (dynamic) version of Singwi, Tosi, Land, and ... -
Guiding, bending, and splitting of electromagnetic waves in highly confined photonic crystal waveguides
(American Physical Society, 2001)We have experimentally demonstrated the guiding, bending, and splitting of electromagnetic (EM) waves in highly confined waveguides built around three-dimensional layer-by-layer photonic crystals by removing a single rod. ... -
Intravascular extended sensitivity (IVES) MRI antennas
(John Wiley & Sons, Inc, 2003)The design and application of an intravascular extended sensitivity (IVES) MRI antenna is described. The device is a loopless antenna design that incorporates both an insulating, dielectric coating and a winding of the ... -

Negative refraction and superlens behavior in a two-dimensional photonic crystal
(American Physical Society, 2005)We experimentally and theoretically studied a left-handed structure based on a photonic crystal (PC) with a negative refractive index. The structure consists of triangular array of rectangular dielectric bars with dielectric ... -
Rydberg aggregates
(Institute of Physics Publishing, 2018)We review Rydberg aggregates, assemblies of a few Rydberg atoms exhibiting energy transport through collective eigenstates, considering isolated atoms or assemblies embedded within clouds of cold ground-state atoms. We ... -
A sketch of a system of theory and practice
(Sage Publications Ltd, 2015)Most political theorists are committed to one particular view about the relation between theory and practice. It is argued in this article that there are in fact four possible ways of relating theory and practice, which ... -
Spin correlations in electron liquids: Analytical results for the local-field correction in two and three dimensions
(Springer, 1998)We study the spin correlations in two- and three-dimensional electron liquids within the sum-rule version of the self-consistent field approach of Singwi, Tosi, Land, and Sjölander. Analytic expressions for the spin-antisymmetric ... -
Spin-dependent analysis of two-dimensional electron liquids
(The American Physical Society, 2002)Two-dimensional electron liquid (2D EL) at full Fermi degeneracy is revisited, giving special attention to the spin-polarization effects. First, we extend the recently proposed classical-map hypernetted-chain (CHNC) technique ... -
SPT-function and its properties
(Bilkent University, 2014)In this thesis, we survey some properties of the spt-function. We start with providing some background information for q-series and the partition function p(n). Then we define the spt-function and study its generating ... -
A systematic theory of tradition
(Brill Academic Publishers, 2016)We still lack a systematic or complete theory of tradition. By referring to the works of many major figures of the last century - Arendt, Boyer, Eisenstadt, Eliot, Gadamer, Goody, Hobsbawm, Kermode, Leavis, MacIntyre, ... -
Taming the boojum: Being theoretical about peculiarities of learning
(Psychonomic Society, Inc., 2022)The case of the “biological constraints” movement in mid-20th-century psychology provides a reminder of the weight of psychology’s reliance on theory and theory-driven methods. By 1980, a critical mass of demonstrations ... -
Three arguments relevant to the history and theory of monarchy
(Taylor & Francis, 2021-04-15)This article states a claim about the fundamental nature of monarchy as something which in antiquity and medievality straddled the immanent and transcendent worlds but which is only half understood in a modernity where the ...
