description: A Bayesian multi-planet Kepler periodogram has been developed for the analysis of precision radial velocity data (Gregory 2005b and 2007). The periodogram employs a parallel tempering Markov chain Monte Carlo algorithm. The HD 11964 data (Butler et al. 2006) has been re-analyzed using 1, 2, 3 and 4 planet models. Assuming that all the models are equally probable a priori, the three planet model is found to be >= 600 times more probable than the next most probable model which is a two planet model. The most probable model exhibits three periods of 38.02+0.06-0.05, 360+-4 and 1924+44-43 d, and eccentricities of 0.22+0.11-0.22, 0.63+0.34-0.17 and 0.05+0.03-0.05, respectively. Assuming the three signals (each one consistent with a Keplerian orbit) are caused by planets, the corresponding limits on planetary mass (M sin i) and semi-major axis are 0.090+0.15-0.14 M_J, 0.253+-0.009 au, 0.21+0.06-0.07 M_J, 1.13+-0.04 au, 0.77+-0.08 M_J, 3.46+-0.13 au, respectively. The small difference (1.3 sigma) between the 360 day period and one year suggests that it might be worth investigating the barycentric correction for the HD 11964 data.

description: When particulate suspensions are sheared, perturbations in the shear flows around the rigid particles increase the local energy dissipation, so that the viscosity of the suspension is effectively higher than that of the solvent. For bulk (three-dimensional) fluids, understanding this viscosity enhancement is a classic problem in hydrodynamics that originated over a century ago with Einstein's study of a dilute suspension of spherical particles. \cite{Einstein1} In this paper, we investigate the analogous problem of the effective viscosity of a suspension of disks embedded in a two-dimensional membrane or interface. Unlike the hydrodynamics of bulk fluids, low-Reynolds number membrane hydrodynamics is characterized by an inherent length scale generated by the coupling of the membrane to the bulk fluids that surround it. As a result, we find that the size of the particles in the suspension relative to this hydrodynamic length scale has a dramatic effect on the effective viscosity of the suspension. Our study also helps to elucidate the mathematical tools needed to solve the mixed boundary value problems that generically arise when considering the motion of rigid inclusions in fluid membranes.

description: Since 2011, Auburn University’s College of Education has led the Global Studies in Education: South Korea program, providing over 85 Alabama educators with direct exposure to Korean culture and educational practices. This 10-day experience helps educators build cultural understanding, which in turn strengthens their teaching practices and their ability to connect with students from different cultural and linguistic backgrounds. Evaluation results show that participants return with new insights and skills that improve how they engage with students and families from international backgrounds. Expanding these types of global learning opportunities is a valuable investment in preparing educators to meet the needs of today’s classrooms and prepare students for a globally connected future.
Rotation profiles of solar-like stars with magnetic fields

Subjects: subject: Astrophysics (astro-ph)

description: The aim of this work is to investigate rotation profile of solar-like stars with magnetic fields. A diffusion coefficient of magnetic angular momentum transport is deduced. Rotating stellar models with different mass are computed under the effect of the coefficient. Then rotation profiles are obtained from the theoretical stellar models. The total angular momentum of solar model with only hydrodynamic instabilities is about 13 times larger than that of the Sun at the age of the Sun, and this model can not reproduce quasi-solid rotation in the radiative region. However, not only can the solar model with magnetic fields reproduce an almost uniform rotation in the radiative region, but its total angular momentum is consistent with helioseismic result at the level of 3 $σ$ at the age of the Sun. The rotation of solar-like stars with magnetic fields is almost uniform in the radiative region. But there is an obvious transition region of angular velocity between the convective core and the radiative region of models with 1.2 - 1.5 $M_{\odot}$, where angular velocity has a sharp radial change, which is different from the rotation profile of the Sun and massive stars with magnetic fields. Moreover the changes of the angular velocity in the transition region increase with the increasing in the age and mass.

Intra-urban industrial linkages and rail terminal location
Creators: name: Torchinsky, Raymon L.
Publisher: name: University of British Columbia
Year: 2010

description: It has been suggested that declining urban freight transport costs have lessened the importance of industrial linkage as a factor in intra-urban industrial location, resulting in the suburbanization of industrial activity. Inner city industrial areas have been characterized as 'zones in transition', implying that such areas do not constitute efficient use of land in the context of modern urban spatial organization. This thesis examines the industrial linkages associated with Vancouver's inner city rail terminal, located on the north shore of False Creek, in order to test the hypothesis that the firms remaining in the vicinity of the terminal form a viable industrial complex focused on the terminal operation. Data gathered in 1975 for a comprehensive survey of Vancouver trucking operations is adapted and analyzed to determine terminal-related linkage patterns. A comparison with the linkages associated with Vancouver's other, rail/truck general freight terminal shows the similarity of the two terminals' impact on the distribution of local industries. In both cases transport costs are an important factor in explaining linkage patterns. The persistence of industrial activity in the inner city can thus be attributed to the continuing influence of transport-related factors, supporting the hypothesis that an inner, city location is not necessarily transitional or inefficient, for industrial firms. However, nonterminal linkages of inner city firms do not diminish with distance; the viability of this complex will be adversely affected by the proposed relocation of the False-Creek terminal to a suburban site.

description: Motivated by recent discovery of yttrium-based high-temperature ternary superconducting hydrides (e.g., CaYH$_{12}$, LaYH$_{12}$, and ScYH$_{6}$), we have employed evolutionary algorithm and first-principles calculations to comprehensively examine the structural stability and superconductivity of the YMgH$_{x}$ system at high pressure. The hydrogen content $x$ and the pressure are both important factors in the stability of these candidate structures. We find that the stability of hydrogen-rich materials frequently necessitates higher pressure. For instance, the pressures to stabilize $P4/mmm$-YMgH$_{8}$ and $Cmmm$-YMgH$_{12}$ are both more than 250 GPa. Hydrogen-less materials, such as $I4_{1}/amd$-YMgH$_{2}$ and $P6_{3}/mmc$-YMgH$_{3}$, can be stable at pressures as low as 100 GPa. In addition, we find a metastable structure for YMgH$_{6}$ with the same space group as the $P4/mmm$-YMgH$_{8}$. A metastable sodalite-like face-centered cubic (FCC) structure is also found in YMgH$_{12}$. These four clathrate structures of $P4/mmm$-YMgH$_{6}$, $P4/mmm$-YMgH$_{8}$, $Cmmm$-YMgH$_{12}$, and $Fd\bar{3}m$-YMgH$_{12}$ is made up of H14, H18, H24, and H24 cages, respectively, in which the H-H pair exhibits weak covalent bonding. According to phonon calculations, $P4/mmm$-YMgH$_{6}$ and $P4/mmm$-YMgH$_{8}$ require a pressure of 300 GPa to maintain dynamic stability, however $Cmmm$-YMgH$_{12}$ and $Fd\bar{3}m$-YMgH$_{12}$ can maintain dynamic stability at pressures of 200 GPa and 250 GPa, respectively. Electron-phonon coupling calculations indicate that they might be potential high-temperature superconductors, with superconductivity intimately linked to the H cage structure. The sodalite structure $Fd\bar{3}m$-YMgH$_{12}$ has a $T_\mathrm{c}$ value of 190 K and a strong electron-phonon coupling constant of 2.18.

Abstract: P53 (encoding the p53 protein) is one of the most frequently mutated genes in all human cancer diseases. Common missense mutations of p53 abolish its tumor-suppressing function (gain-of-function, GOF) and lead to the development of GOF cancer.

Materials and Methods: The study focused on samples of squamous cell carcinoma (SCC), adenocarcinoma (ADC) of the lungs, and adjacent healthy tissues obtained from postoperative material of cancer patients. Methods included polymerase chain reaction (PCR) of p53 and HRAS gene fragments, as well as complementary DNA (c-DNA) copies of p53, p21Waf1, MDM2, and mutation analysis using EcoR1 and Pst1 endonucleases based on restriction site presence.

Results: The presence of mutations was analyzed after amplification of p53 and HRAS gene fragments, as well as p53, p21Waf1, and MDM2 mRNA in cancerous and adjacent tissues in 100 samples of tumor and normal adjacent tissues. Half of the SCC and ADC lung samples did not contain expression products of p53 or p21Waf1 genes. Mutations were detected in 100% and 85% of SCC samples in 12 and 61 codons of the HRAS gene, and in 75% and 50% of ADC samples, respectively. Conclusion. Mutations found in the majority of SCC and ADC samples allow diagnosing the disease, predicting its severity, and assessing the effectiveness of targeted therapy through such tests.

description: Antiferromagnetic materials with strong spin-phonon coupling have the potential for spintronic applications. Here, we report the structural, magnetic, and vibrational properties of 12R-BaTi0.4Mn0.6O3. Temperature-dependent magnetization data show the presence of weak antiferromagnetic interactions. Correlation between magnetic and vibrational properties are probed by using temperature-dependent Raman spectroscopic measurements. Two of the Raman active phonons show deviation from anharmonic behaviour at low temperatures which can be attributed to spin-phonon coupling. The strength of coupling is estimated using mean-field approximation and is found to be 1.1 and 1.2 cm-1 for phonons at 530 and 717 cm-1, respectively.

Moral Machine Learning: Teaching a Course at the Intersection of Applied Statistics and Moral Philosophy

Publisher: name: Taylor & Francis

description:
Statistical applications are increasingly inducing ethical considerations, which are often not able to be resolved via statistics alone. In this paper, we present a proposed course that combines applied statistics and moral philosophy. The instructional methods included are designed with implementation at a large research institution in mind but are fully intended to be transferable to any setting adopting such an interdisciplinary course into its curriculum. The aforementioned methods will foreground case-studies as tangible examples in a recurrent workflow involving identification of a dilemma, statistical analysis, philosophical defense, and application to the particular case study. Formative and summative assessment mechanisms will be presented alongside future directions and potential pitfalls of such a course. Motivating the proposed course is a desire to fill the comparative void in moral reasoning for statistics and data science curricula.
Does The Addition of a Duration Improve the L_iso - E_peak Relation For Gamma-Ray Bursts?

Subjects: subject: Astrophysics (astro-ph)

description: Firmani et al. proposed a new Gamma Ray Burst (GRB) luminosity relation that showed a significant improvement over the L_iso-E_peak relation. The new proposed relation simply modifies the E_peak value by multiplying it by a power of T_0.45, where T_0.45 is a particular measure of the GRB duration. We begin by reproducing the results of Firmani for his 19 bursts. We then test the Firmani relation for the same 19 bursts except that we use independently measured values for L_iso, T_0.45, and E_peak, and we find that the relation deteriorates substantially. We further test the relation by using 60 GRBs with measured spectroscopic redshifts, and find a relation that has a comparable scatter as the original L_iso-E_peak relation. That is, a much larger sample of bursts does not reproduce the small scatter as reported by Firmani et al. Finally, we investigate whether the Firmani relation is improved by the use of any of 32 measures of duration in place of T_0.45. The quality of each alternative duration measure is evaluated with the root mean square of the scatter between the observed and fitted logarithmic Liso values. Although we find some durations yield slightly better results than T_0.45, the differences between the duration measures are minimal. We find that the addition of a duration does not add any significant improvement to the L_iso-E_peak relation. We also present a simple and direct derivation of the Firmani relation from both the L_iso-E_peak and Amati relations. In all we conclude that the Firmani relation neither has an independent existence nor does it provide any significant improvement on previously known relations that are simpler.

description: The 3D city metaphor in software visualization is a well-explored rendering method. Numerous tools use their custom variation to visualize offline-analyzed data. Heat map overlays are one of these variants. They introduce a separate information layer in addition to the software city's own semantics. Results show that their usage facilitates program comprehension. In this paper, we present our heat map approach for the city metaphor visualization based on live trace analysis. In comparison to previous approaches, our implementation uses live dynamic analysis of a software system's runtime behavior. At any time, users can toggle the heat map feature and choose which runtime-dependent metric the heat map should visualize. Our approach continuously and automatically renders both software cities and heat maps. It does not require a manual or semi-automatic generation of heat maps and seamlessly blends into the overall software visualization. We implemented this approach in our web-based tool ExplorViz, such that the heat map overlay is also available in our augmented reality environment. ExplorViz is developed as open source software and is continuously published via Docker images. A live demo of ExplorViz is publicly available.

description: We consider entropy solutions to the initial value problem associated with scalar nonlinear hyperbolic conservation laws posed on the two-dimensional sphere. We propose a finite volume scheme which relies on a web-like mesh made of segments of longitude and latitude lines. The structure of the mesh allows for a discrete version of a natural geometric compatibility condition, which arose earlier in the well-posedness theory established by Ben-Artzi and LeFloch. We study here several classes of flux vectors which define the conservation law under consideration. They are based on prescribing a suitable vector field in the Euclidean three-dimensional space and then suitably projecting it on the sphere's tangent plane; even when the flux vector in the ambient space is constant, the corresponding flux vector is a non-trivial vector field on the sphere. In particular, we construct here "equatorial periodic solutions", analogous to one-dimensional periodic solutions to one-dimensional conservation laws, as well as a wide variety of stationary (steady state) solutions. We also construct "confined solutions", which are time-dependent solutions supported in an arbitrarily specified subdomain of the sphere. Finally, representative numerical examples and test-cases are presented.

description: We present the results of SiO millimeter-line observations of a sample of known SiO maser sources covering a wide dust-temperature range. A cold part of the sample was selected from the SiO maser sources found in our recent SiO maser survey of cold dusty objects. The aim of the present research is to investigate the causes of the correlation between infrared colors and SiO maser intensity ratios among different transition lines. In particular, the correlation between infrared colors and SiO maser intensity ratio among the J=1-0 v=1, 2, and 3 lines are mainly concerned in this paper. We observed in total 75 SiO maser sources with the Nobeyama 45m telescope quasi-simultaneously in the SiO J=1-0 v=0, 1, 2, 3, 4 and J=2-1 v=1, 2 lines. We also observed the sample in the 29SiO J=1-0 v=0 and J=2-1 v=0, and 30SiO J=1-0 v=0 lines, and the H2O 6(1,6)-5(2,3) line. As reported in previous papers, we confirmed that the intensity ratios of the SiO J=1-0 v=2 to v=1 lines clearly correlate with infrared colors. In addition, we found possible correlation between infrared colors and the intensity ratios of the SiO J=1-0 v=3 to v=1&2 lines. Two overlap lines of H2O (i.e., 11(6,6) nu_2=1 -> 12(7,5) nu_2=0 and 5(0,5) nu_2=2 -> 6(3,4) nu_2=1) might explain these correlation if these overlap lines become stronger with increase of infrared colors, although the phenomena also might be explained by more fundamental ways if we take into account the variation of opacity from object to object.

description: Materials which possess coupling between different degrees of freedom such as charge, spin, orbital and lattice are of tremendous interest due to their potential for device applications. It has been recently realized that some of manganite perovskite oxides show structural and ferroelectric instabilities which may be tuned by imposing internal or external strain. Among manganite perovskites, AMnO3 (A = Ca, Sr and Ba) are reported to be good candidates to show spin-phonon coupling driven multiferroicity. Here, we have probed the correlation between vibrational and magnetic properties in the 9R-type hexagonal Ba0.9Sr0.1MnO3 (BSM10). Nine Raman active modes are observed which are characteristic phonon modes for 9R phase. The frequency ({omega}) of an Eg (344 cm-1) mode which is related to Mn vibrations shows anomaly with temperature (T) manifested as a change in slope of {omega} vs T at 260 K. The temperature-dependent magnetization of BSM10 suggests a possible antiferromagnetic ordering at ~ 260 K. We, therefore, attribute the phonon anomaly to spin-phonon coupling arising due to the magnetic ordering.

description: It has been recently shown that Nambu-Goto action can be re-expressed in terms of Cayley's hyperdeterminant with the manifest SL(2,R) X SL(2,R) X SL(2,R) symmetry. In the present paper, we show that the same feature is shared by Green-Schwarz sigma-model for N=2 superstring whose target space-time is D=2+2. When its zweibein field is eliminated from the action, it contains the Nambu-Goto action which is nothing but the square root of Cayley's hyperdeterminant of the pull-back in superspace \sqrt{\hyperdet(Π_{i \a\Dot\a})} manifestly invariant under SL(2,R) X SL(2,R) X SL(2,R). The target space-time D=2+2 can accommodate self-dual supersymmetric Yang-Mills theory. Our action has also fermionic kappa-symmetry, satisfying the criterion for its light-cone equivalence to Neveu-Schwarz-Ramond formulation for N=2 superstring.

description: Lubrication expressions for the friction coefficients of a spherical particle moving in a fluid between and along two parallel solid walls are explicitly evaluated in the low-Reynolds-number regime. They are used to determine lubrication expression for the particle free motion under an ambient Poiseuille flow. The range of validity and the accuracy of the lubrication approximation is determined by comparing with the corresponding results of the accurate multipole procedure. The results are applicable for thin, wide and long microchannels, or quasi-two-dimensional systems.

description: We are interested in nonlinear hyperbolic systems in nonconservative form arising in fluid dynamics, and, for solutions containing shock waves, we investigate the convergence of finite difference schemes applied to such systems. According to Dal Maso, LeFloch, and Murat's theory, a shock wave theory for a given nonconservative system requires prescribing a priori a family of paths in the phase space. In the present paper, we consider schemes that are formally consistent with a given family of paths, and we investigate their limiting behavior as the mesh is refined. We generalize to systems a property established earlier by Hou and LeFloch for scalar conservation laws, and we prove that nonconservative schemes generate, at the level of the limiting hyperbolic system, a "convergence error" source-term which, provided the total variation of the approximations remains uniformly bounded, is a locally bounded measure. We discuss the role of the equivalent equation associated with a difference scheme; here, the distinction between scalar equations and systems appears most clearly since, for systems, the equivalent equation of a scheme that is formally path-consistent depends upon the prescribed family of paths. The core of this paper is devoted to investigate numerically the approximation of several models arising in fluid dynamics. For systems having nonconservative products associated with linearly degenerate characteristic fields, the convergence error vanishes. For some other models, this measure is evaluated very accurately, especially by plotting the shock curves associated with each scheme under consideration.

description: We assessed whether estimation of follicular growth, rather than actual measurement of follicular size on the day of hCG trigger, affected pregnancy rates in intrauterine insemination (IUI) cycles. Patient and cycle characteristics were extracted from an existing database. Comparisons were made between the pregnant (defined as a positive beta hCG) and non-pregnant groups for the following variables: patient’s age, number of previous IUI cycles, type of ovarian stimulation, endometrial thickness, number of follicles measuring 14 mm and above, pre and post wash sperm parameters, cycle day when IUI was done and number of days between last ultrasound scan and ovulation trigger. A total of 7302 cycles were included in the final analysis. In 4055 cycles (55.5%) the hCG trigger was on the day of the last ultrasound, in 2285 cycles (31.3%) the hCG trigger was 1 day after the last ultrasound, in 850 (11.6%) it was 2 days after the last ultrasound and in 112 (1.5%) it was 3 or more days after the last ultrasound. Sperm parameters, younger maternal age, and the number of follicles above 14 mm were all associated with pregnancy. No association was found between positive pregnancy test rates and the time from last ultrasound to hCG trigger. Planning IUI based on the estimation of follicular growth 1–4 days before trigger, does not affect pregnancy rates.

In the transitions, the classical broad H$α$ emission fades away since 2013, and disappears in our 2021 spectrum, although the absence of broad H$β$ can be traced back to at least 2016. A follow-up observation in X-rays by the {\it Swift}/XRT reveals that (1) the X-ray emission level gradually decreases since 2005; and (2) the X-ray spectrum is soft in the optical "turn-off" state and hard in the "turn-on" state. We argue that the disappearance of the classical broad H$α$ emission can be likely explained by the disk-wind broad-line-region model, in which the CL phenomenon is sensitive to luminosity in individual AGNs.

description: While multiple testing procedures have been the focus of much statistical research, an important facet of the problem is how to deal with possible confounding. Procedures have been developed by authors in genetics and statistics. In this chapter, we relate these proposals. We propose two new multiple testing approaches within this framework. The first combines sensitivity analysis methods with false discovery rate estimation procedures. The second involves construction of shrinkage estimators that utilize the mixture model for multiple testing. The procedures are illustrated with applications to a gene expression profiling experiment in prostate cancer.

description: The present study aimed to explore whether lesbian women’s preferences for a sperm donor or a long-term mate show a pattern similar to those of heterosexual women. Three hundred and eighty-three donor insemination patients, of whom 278 were heterosexual and 105 were lesbian, completed a questionnaire comprising a series of 35 traits and rated the importance of each trait in a sperm donor and again in a long term mate. Results showed that traits relating to socioeconomic status, genetic background and general health, physical appearance, and personality were rated by lesbian women as more important in a long-term mate than in a sperm donor. It was further found that both heterosexual and lesbian women attached higher importance to the socioeconomic status, personality and physical appearance of the long-term mate than of the sperm donor; heterosexual women attached similar importance to the genes and health of a long-term mate and a sperm donor, while lesbian women attached greater importance to the genetic background and general health of the sperm donor than those of a long-term mate. The implications and interpretations of the findings are discussed in light of Trivers’ parental investment theory.

When elasticity affects drop coalescence

description: The breakup and coalescence of drops are elementary topological transitions in interfacial flows. The breakup of a drop changes dramatically when polymers are added to the fluid. With the strong elongation of the polymers during the process, long threads connecting the two droplets appear prior to their eventual pinch-off. Here, we demonstrate how elasticity affects drop coalescence, the complement of the much studied drop pinch-off. We reveal the emergence of an elastic singularity, characterised by a diverging interface curvature at the point of coalescence. Intriguingly, while the polymers dictate the \emph{spatial} features of coalescence, they hardly affect the \emph{temporal} evolution of the bridge. These results are explained using a novel viscoelastic similarity analysis and are relevant for drops created in biofluids, coating sprays and inkjet printing.

TeV scale model for neutrino masses, dark matter and leptogenesis

description: We present a TeV scale model for leptogenesis where the origin of neutrino masses are independent of the scale of leptogenesis. As a result, the model could be extended to explain {\it dark matter, neutrino masses and leptogenesis at the TeV scale}. The most attractive feature of this model is that it predicts a few hundred GeV triplet Higgs scalar that can be tested at LHC or ILC.

description: Congenital uterine anomalies have been proven to be associated with impaired reproductive performance. The 2013 ESHRE-ESGE classification of female genital tract malformations defines T shaped and infantalis uterus as dysmorphic uterus. Our aim was to examine whether the reproductive performance of patients with primary congenital dysmorphic uterus can be improved using hysteroscopic metroplasty. A retrospective cohort study of 35 patients suffering from 1 year of failed attempts to conceive, recurrent early pregnancy losses, or repeated implantation failures of in vitro fertilization cycles who were diagnosed with a dysmorphic uterus in both a diagnostic hysteroscopy procedure and three-dimensional transvaginal ultrasound (3D-TVS). All patients had undergone an operative hysteroscopic procedure for uterine anomaly repair and their reproductive performance is described before and after the procedure, so that the women acted as their own control. Within 3 years of the procedure, a total of 25 patients (71.4%) reported that they had achieved a pregnancy. A total of 15% of patients only conceived for the first time after the procedure, 15 patients (42.9%) conceived within 6 months and 18 (51.4%) within 1 year. A total of 12 of the 25 pregnant patients (48%) gave birth to a live newborn. We conclude that in non-DES exposed patients with impaired reproductive performance and congenital dysmorphic uterus, hysteroscopic metroplasty for uterine repair could serve as a treatment option for recurrent implantation failure, and may lead to improved reproductive performance and obstetric outcome.

Seiberg--Witten maps for $\boldsymbol{SO(1,3)}$ gauge invariance and deformations of gravity

Subjects: subject: High Energy Physics - Theory (hep-th)

description: A family of diffeomorphism-invariant Seiberg--Witten deformations of gravity is constructed. In a first step Seiberg--Witten maps for an SO(1,3) gauge symmetry are obtained for constant deformation parameters. This includes maps for the vierbein, the spin connection and the Einstein--Hilbert Lagrangian. In a second step the vierbein postulate is imposed in normal coordinates and the deformation parameters are identified with the components $θ^{μν}(x)$ of a covariantly constant bivector. This procedure gives for the classical action a power series in the bivector components which by construction is diffeomorphism-invariant. Explicit contributions up to second order are obtained. For completeness a cosmological constant term is included in the analysis. Covariant constancy of $ θ^{μν}(x) $, together with the field equations, imply that, up to second order, only four-dimensional metrics which are direct sums of two two-dimensional metrics are admissible, the two-dimensional curvatures being expressed in terms of $θ^{μν}$. These four-dimensional metrics can be viewed as a family of deformed emergent gravities.

description: We present a detailed analytical theory for the plasmonic nanoring configuration first proposed in [A. Alu, A. Salandrino, N. Engheta, Opt. Expr. 14, 1557 (2006)], which is shown to provide negative magnetic permeability and negative index of refraction at infrared and optical frequencies. We show analytically how the nanoring configuration may provide superior performance when compared to some other solutions for optical negative index materials, offering a more 'pure' magnetic response at these high frequencies, which is necessary for lowering the effects of radiation losses and absorption. Sensitivity to losses and the bandwidth of operation of this magnetic inclusion are also investigated in details and compared with other available setups.
