description: This paper presents improved techniques for identifying coherent generators and consequent power system reduction for use in power systems transient stability studies. The power system equivalent model can represent effectively the dynamic and steady state states of the original power system supplying loads represented by its static characteristics. The coherency identification procedure is valid for complex and large-scale power systems on PC environments, as it require low memory and run time. The proposed identification and reduction techniques is applied to 39 bus, 10 generator NPCC system and transient stability evaluation of the proposed technique show excellent agreement between the responses of the actual system and its equivalent. The principal aim of this work is to clarify and improve the principle of coherency based power system equivalents, also it facilities the practical application of electromechanical equivalent process.

description: We identified Brightest Cluster Members (BCM) on DSS images of 1083 Abell clusters, derived their individual and host cluster redshifts from literature and determined the BCM ellipticity. Half the BCMs move at a speed higher than 37 % of the cluster velocity dispersion sigma_{cl}, suggesting that most BCMs are part of substructures falling into the main cluster. Both, the BCM's velocity offset in units of sigma_{cl}, and BCM ellipticity, weakly decrease with cluster richness.

Dark matter stability and one-loop neutrino mass generation based on Peccei-Quinn symmetry

Year: 2017
Subjects: subject: High Energy Physics - Phenomenology (hep-ph)

description: We propose a model which is a simple extension of the KSVZ invisible axion model with an inert doublet scalar. Peccei-Quinn symmetry forbids tree-level neutrino mass generation and its remnant $Z_2$ symmetry guarantees dark matter stability. The neutrino masses are generated by one-loop effects as a result of the breaking of Peccei-Quinn symmetry through a nonrenormalizable interaction. Although the low energy effective model coincides with an original scotogenic model which contains right-handed neutrinos with large masses, it is free from the strong $CP$ problem.

description: Descaudatine A (1), an undescribed phenolic glycoside, along with a known analogue (2) and ten flavonoids (3-12), were isolated from the whole plant of Desmodium caudatum. Compounds 1 and 4 exhibited potent antioxidant activities with the IC50 of 58.59 μM and 31.31 μM, respectively, which were approached to that of the positive control Vitamin C (IC50 = 46.32 μM). Meanwhile, 12 showed moderate antioxidant activity with the IC50 of 173.9 μM. Besides, compounds 3 and 6 inhibited the proliferation of HeLa cells with IC50 values of 56.14 μM and 69.04 μM, respectively. Further studies indicated that 3 and 6 could dose-dependently induce PARP cleavage and might trigger caspase-3, 8, 9 activation to induce apoptosis. RXRα is an ideal anticancer target of nuclear receptor. The reporter gene assay of RXRα indicated that 3 and 6 could inhibited the 9-cis-RA induced RXRα transcription in a concentration-dependent manner.

description: We represent Polyakov loops and their correlators as spectral sums of eigenvalues and eigenmodes of the lattice Dirac operator. The deconfinement transition of pure gauge theory is characterized as a change in the response of moments of eigenvalues to varying the boundary conditions of the Dirac operator. We argue that the potential between static quarks is linked to spatial correlations of Dirac eigenvectors.

description: Identifying the most influential spreaders is one of outstanding problems in physics of complex systems. So far, many approaches have attempted to rank the influence of nodes but there is still the lack of accuracy to single out influential spreaders. Here, we directly tackle the problem of finding important spreaders by solving analytically the expected size of epidemic outbreaks when spreading originates from a single seed. We derive and validate a theory for calculating the size of epidemic outbreaks with a single seed using a message-passing approach. In addition, we find that the probability to occur epidemic outbreaks is highly dependent on the location of the seed but the size of epidemic outbreaks once it occurs is insensitive to the seed. We also show that our approach can be successfully adapted into weighted networks.

The interplay between social and environmental plasticity in the rapid adaptation of a Hawaiian field cricket (Teleogryllus oceanicus)

description: The role of phenotypic plasticity in genetic adaptation has been at the centre of a decades long debate. Recent research has revealed that the potential for plasticity-led adaptation is highly conditional, dependant on the intrinsic characteristics of a plastic response and the selection pressures acting on it. However, the fact that the potential for plasticity-led adaptation is susceptible to multiple environmental conditions, given that phenotypes are expressed in an interdependent ecological and social context, has been inadvertently neglected. In this thesis, I investigate the intricate relationship between social and environmental plasticity in the rapid adaptation of the Hawaiian Field Cricket (Teleogryllus oceanicus). Ancestrally reliant on acoustic signals for sexual advertising, selection from an acoustically orienting parasitoid fly (Ormia ochracea) has led to the emergence of a silent male morph (induced by the flatwing mutation). Adaptive behavioural adjustments in the new morph, coupled with permissive female choice, are thought to have accommodated the absence of an important sexual signal. Flatwing males show higher propensity to engage in phonotactic behaviour and socially-plastic locomotory activity, facilitating encounters with conspecifics. Here, I investigate how different components of the abiotic and social environments interact to shape the expression of traits that promote flatwing evolution at the behavioural and genetic level. Through dietary and social environment manipulation, Chapter 2 revealed that direct and indirect, genetic and environmental effects influenced female mating behaviour and male courtship. In Chapter 3, I identified the genetic substrate involved in socially-plastic adaptations in flatwing males. Chapter 4 showed that the outcome of social interactions between females was dependent on multiple social environment components, and Chapter 5 revealed that previously observed female preferences dissipate in a group context. These findings underscore the importance of considering multiple sources of plasticity and their interactions to fully grasp the evolutionary consequences of phenotypic plasticity.

description: This paper presents a new technique for constructing an electromechanical equivalent of large-scale power systems for use in transient stability studies. A large-scale power system is divided into a study system, an external system, and a remote system. Moreover the external system is subdivided into a set of coherency-based external areas (EA). The power system equivalent model can represent effectively the dynamic and steady state states of the original power system. The proposed reduction technique is applied to 77-bus, 19-generator system and transient stability evaluation using the proposed technique show excellent agreement between the responses of the actual system and its equivalent.
Finite Temperature Schwinger Model with Chirality Breaking Boundary Conditions

description: The $N_f$-flavour Schwinger Model on a finite space $0\leq x^1\leq L$ and subject to bag-type boundary-conditions at $x^1=0$ und $x^1=L$ is solved at finite temperature $T=1/β$. The boundary conditions depend on a real parameter $θ$ and break the axial flavour symmetry. We argue that this approach is more appropriate to study the broken phases than introducing small quark masses, since all calculations can be performed analytically. In the imaginary time formalism we determine the thermal correlators for the fermion-fields and the determinant of the Dirac-operator in arbitrary background gauge-fields. We show that the boundary conditions induce a CP-odd $θ$-term in the effective action. The chiral condensate, and in particular its T- and L- dependence, is calculated for $N_f$ fermions. It is seen to depend on the order in which the two lengths $β=1/T$ and $L$ are sent to infinity.

description: We use various samples of compact groups (CGs) to examine the types of association CGs have with rich and poor clusters of galaxies at low (z~0.04) and intermediate (z~0.1) redshifts. We find that ~10-20 % of CGs are associated with rich clusters and a much larger fraction with poorer clusters or loose groups. Considering the incompleteness of catalogs of poorer systems at intermediate redshift, our result is consistent with all CGs at intermediate redshift being associated with larger-scale systems. The richness of the clusters associated with CGs significantly increases from z~0.04 to z~0.1, while their Bautz-Morgan type changes from early to late type for the same range in z. Neither trend is compatible with a selection effect in the cluster catalogs used. We find earlier morphological types of galaxies to be more frequent in CGs associated with larger-scale structures, compared to those in CGs not associated to such structures. We consider this as new evidence that CGs are part of the large-scale structure formation process and that they may play an important role in the evolution of galaxies in these structures.

Perfect Anomalous Reflection with a Binary Huygens' Metasurface

Publisher: name: arXiv
Year: 2017
Subjects: subject: Applied Physics (physics.app-ph)

description: In this paper we propose a new metasurface that is able to reflect a known incoming electromagnetic wave into an arbitrary direction, with perfect power efficiency. This seemingly simple task, which we hereafter call perfect anomalous reflection, is actually highly non-trivial due to the differing wave impedances and complex interference between the incident and reflected waves. Heretofore, proposed metasurfaces which achieve perfect anomalous reflection require complicated, deeply subwavelength and/or multilayer element structures which allow them to couple to and from leaky and/or evanescent waves. In contrast, we demonstrate that using a Binary Huygens' Metasurface (BHM) --- a passive and lossless metasurface with only two cells per period --- perfect anomalous reflection can be achieved over a wide angular and frequency range. Through simulations and experiments at 24 GHz, we show that a properly designed BHM can anomalously reflect an incident electromagnetic wave from $θ_i = 50^\circ$ to $θ_r = -22.5^\circ$, with perfect power efficiency to within experimental precision.

description: For compact U(1) lattice gauge theory (LGT) we have performed a finite size scaling analysis on $N_τ N_s^3$ lattices for $N_τ$ fixed by extrapolating spatial volumes of size $N_s\le 18$ to $N_s\to\infty$. Within the numerical accuracy of the thus obtained fits we find for $N_τ=4$, 5 and~6 second order critical exponents, which exhibit no obvious $N_τ$ dependence. The exponents are consistent with 3d Gaussian values, but not with either first order transitions or the universality class of the 3d XY model. As the 3d Gaussian fixed point is known to be unstable, the scenario of a yet unidentified non-trivial fixed point close to the 3d Gaussian emerges as one of the possible explanations.

description: This paper presents an improved technique for constructing a dynamic equivalent of a power system load consists of induction motors and static loads interconnected by a network. The aggregate model can represent effectively the dynamic and steady state effects of the original load. The technique takes into consideration the effect of the network on the aggregate model, also there is no constraints placed on the loading of the induction motors in the system. The technique is universal and can be applied to any industrial plants with high concentration of induction motor loads, also all the parameters of the equivalent dynamic loads can be determined systematically and there is either no need of any measurements or applying any parameter estimation methods. The technique is validated by comparing the response of the original system and its aggregate as the power system is subjected to various types of faults.

description: We report results of a nine-year monitoring effort on the unusual classical Be with a robotic ground-based (APT) B,V-filtered telescope as well as simultaneous observations in 2004 November with this instrument and the RXTE (X-ray) telescope. Our observations disclosed no correlated optical response to the rapid X-ray flares in this star, nor did the star show any sustained flux changes during the course of either of the two monitored nights in either wavelength regime. Our optical light curves reveal that gamma Cas undergoes \~3%-amplitude cycles with lengths of 60--90 days. Over the nine days we monitored the star with the RXTE, the X-ray flux varied in phase with its optical cycle and with an amplitude predicted from correlated optical/X-ray data from an earlier paper. The amplitudes of the V magnitude cycles are 30--40% larger than the B amplitudes, suggesting the seat of the cycles is circumstellar. The cycle lengths constantly change and can damp or grow on timescales as short as 13 days. We have also discovered a coherent period of 1.21581 +/-0.00002 days in all our data, which is consistent only with rotation. The full amplitude of this variation is 0.0060 in both filters. The derived waveform, somewhat surprisingly, is almost sawtooth in shape. This variation probably originates on the star's surface. This circumstance hints at the existence of a strong magnetic field with a complex topology and an associated heterogeneous surface composition.

description: This paper presents a new technique for enhancement oftransient stability analysis of large-scale power systems through integrated electromechanical equivalent and dynamic load aggregation. Various degrees of power system reduction models are compared through transient stability simulations to evaluate the confidence level in the proposed technique. The proposed power system reduced model can represent effectively the dynamic and steady state states ofthe original power system with dynamic loads represented by induction motor third-order model. The proposed integrated reduction technique is applied to 39-bus, 10 generator NPCC system that feeds, at bus 38, a dynamic load subsystem consists of 5-induction motors interconnected by a network. Transient stability evaluation of the proposed integrated reduction technique shows excellent agreement between the responses of the original system and its proposed reduced model.

description: We study cosmological perturbations in mimetic gravity in the presence of classified higher derivative terms which can make the mimetic perturbations stable. We show that the quadratic higher derivative terms which are independent of curvature and the cubic higher derivative terms which come from curvature corrections are sufficient to remove instabilities in mimetic perturbations. The advantage of working with the classified higher derivative terms is that we can control both the background and the perturbation equations allowing us to construct the higher derivative extension of mimetic dark matter and the mimetic nonsingular bouncing scenarios. The latter can be thought as a new higher derivative effective action for the loop quantum cosmology scenario in which the equations of motion coincide with those suggested by loop quantum cosmology. We investigate a possible connection between the mimetic cosmology and the Randall-Sundrum cosmology.

description: It is proposed that asymptotically nonfree gauge theories are consistently interpreted as theories of composite gauge bosons. It is argued that when hidden local symmetry is introduced, masslessness and coupling universality of dynamically generated gauge boson are ensured. To illustrate these ideas we take a four dimensional Grassmannian sigma model as an example and show that the model should be regarded as a cut-off theory and there is a critical coupling at which the hidden local symmetry is restored. Propagator and vertex functions of the gauge field are calculated explicitly and existence of the massless pole is shown. The beta function determined from the $ Z $ factor of the dynamically generated gauge boson coincides with that of an asymptotic nonfree elementary gauge theory. Using these theoretical machinery we construct a model in which asymptotic free and nonfree gauge bosons coexist and their running couplings are related by the reciprocally proportional relation.

High barriers for tunnelling among different twist sectors are overcome through parallel tempering. Monopole condensation is used to study the deconfinement transition and the properties of the confined phase. Ergodicity in summing over all twist sectors allows an unbiased measure of the 't Hooft vortices free energy. Its behaviour in the SO(3) confined phase hints at differences from what conjectured for semi-integer discretizations.

description: Dysregulation of the intestinal barrier has been associated with chronic inflammatory immune diseases, including food allergy, inflammatory bowel disease (IBD), and autoimmune disease. As an autoimmune disease, rheumatoid arthritis (RA) has been shown impaired intestinal barrier function before the clinical onset of arthritis. Whether or not intestinal epithelial barrier function is a primary etiologic factor in the predisposition to disease development remains largely unknown. However, clinical and experimental evidence supports a role for intestinal epithelial barrier dysfunction in disease pathogenesis. For instance, epithelial barrier dysfunction could create hypoxic micro-environments, mainly regulated by hypoxia-inducible transcription factors (HIFs). Studies have shown that HIFs trigger the expression of genes, such as mucins (e.g., Muc-3), intestinal trefoil factor (TTF3), and P-glycoprotein (P-GP, Mdr-1 gene product), allowing intestinal epithelial cells to function as an effective barrier. Understanding how these processes impact barriers remains largely unclear, particularly in rheumatoid arthritis (RA). Here, we investigated the roles of intestinal HIF1α and HIF2α during the development of RA. We also demonstrated that disruption of intestinal HIF1α and HIF2α leads to different phenotypes in the collagen-induced arthritis murine model. Loss of intestinal HIF1α results in severe arthritis in the murine CIA model, and exacerbation of arthritis correlates with an increase of intestinal IgA+ B cells, Th1, Th17 cells. Conversely, disruption of intestinal HIF2α alleviates arthritis. HIF2α was able to regulate epithelial barrier integrity by selectively controlling tight junction Claudin 15. HIF2α deficient arthritic mice displayed less inflammation in the small intestine, thereby decreasing the systemic immune cells activation, such as Th1, Th17, Treg cells, and Dendritic cells. The administration of HIF2α inhibitor act as a treatment approach against RA. Collectively, these studies reveal HIF1α and HIF2α’s critical role in maintaining barriers and highlight the HIF2α/Claudin 15 axis as a potential therapeutic target for RA.

description: An important and perhaps critical clue to the mechanism driving the explosion of massive stars as supernovae is provided by the accumulating evidence for asymmetry in the explosion. Indirect evidence comes from high pulsar velocities, associations of supernovae with long-soft gamma-ray bursts, and asymmetries in late-time emission-line profiles. Spectropolarimetry provides a direct probe of young supernova geometry, with higher polarization generally indicating a greater departure from spherical symmetry. Large polarizations have been measured for 'stripped-envelope' (that is, type Ic) supernovae, which confirms their non-spherical morphology; but the explosions of massive stars with intact hydrogen envelopes (type II-P supernovae) have shown only weak polarizations at the early times observed. Here we report multi-epoch spectropolarimetry of a classic type II-P supernova that reveals the abrupt appearance of significant polarization when the inner core is first exposed in the thinning ejecta (~90 days after explosion). We infer a departure from spherical symmetry of at least 30 per cent for the inner ejecta. Combined with earlier results, this suggests that a strongly non-spherical explosion may be a generic feature of core-collapse supernovae of all types, where the asphericity in type II-P supernovae is cloaked at early times by the massive, opaque, hydrogen envelope.

description: Recently, there has been growing interest in employing condensed matter systems such as quantum spin or harmonic chains as quantum channels for short distance communication. Many properties of such chains are determined by the spectral gap between their ground and excited states. In particular this gap vanishes at critical points of quantum phase transitions. In this article we study the relation between the transfer speed and quality of such a system and the size of its spectral gap. We find that the transfer is almost perfect but slow for large spectral gaps and fast but rather inefficient for small gaps.

description: It is imperative that any proposal of new physics possesses a Higgs-like boson with 125 GeV of mass and couplings with the standard particles that recover the branching ratios and signal strengths as measured by CMS and ATLAS. We address this issue within the supersymmetric version of the minimal 3-3-1 model. For this we develop the Higgs potential with focus on the lightest Higgs provided by the model. Our proposal is to verify if it recovers the properties of the standard Higgs. With respect to its mass, we calculate it up to one loop level by taking into account all contributions provided by the model. In regard to its couplings, we restrict our investigation to couplings of the Higgs-like boson with the standard particles, only. We then calculate the dominant branching ratios and the respective signal strengths and confront our results with the recent measurements of CMS and ATLAS. As distinctive aspects, we remark that our Higgs-like boson intermediates flavor changing neutral processes and then argue that its signature is the decay $t \rightarrow h+c$. We calculate its branching ratio and compare it with current bounds. We also show that the potential is stable for the region of parameter space employed in our calculations.

description: This paper presents a developed formulation for selection of optimal number and locations of sectionalizing device in medium tension radial distribution system taking into consideration outage, maintenance and investment costs. The problem falls into the class of " discrete variable optimization problem with single minimum ". A solution is proposed to determine (i) the number of sectionalizing switches and (ii) the locations of these switches. The proposed solution methodology offers a general solution for optimal number and location of sectionalizing device problem including the reliability, investment, and maintenance costs. The research illustrates that feeder sectionalization automation plays a key role in the reliability of radial distribution systems.
Fractional Hopfions in the Faddeev-Skyrme model with a symmetry breaking potential

description: We construct new solutions of the Faddeev-Skyrme model with a symmetry breaking potential admitting $S^1$ vacuum. It includes, as a limiting case, the usual $SO(3)$ symmetry breaking mass term, another limit corresponds to the potential $m^2 ϕ_1^2$, which gives a mass to the corresponding component of the scalar field. However we find that the spacial distribution of the energy density of these solutions has more complicated structure, than in the case of the usual Hopfions, typically it represents two separate linked tubes with different thicknesses and positions. In order to classify these configurations we define a counterpart of the usual position curve, which represents a collection of loops $\mathcal{C}_1, \mathcal{C}_{-1}$ corresponding to the preimages of the points $\vec ϕ= (\pm 1 \mp μ, 0,0)$, respectively. Then the Hopf invariant can be defined as $Q= {\rm link} (\mathcal{C}_1,\mathcal{C}_{-1})$. In this model, in the sectors of degrees $Q=5,6,7$ we found solutions of new type, for which one or both of these tubes represent trefoil knots. Further, some of these solutions possess different types of curves $\mathcal{C}_1$ and $\mathcal{C}_{-1}$.

description: We calculate the pi+ K+ scattering length in fully-dynamical lattice QCD with domain-wall valence quarks on MILC lattices with rooted staggered sea-quarks at a lattice spacing of b=0.125 fm, lattice spatial size of L =2.5 fm and at pion masses of m_pi=290, 350, 490 and 600 MeV. The lattice data, analyzed at next-to-leading order in chiral perturbation theory, allows an extraction of the full pi K scattering amplitude at threshold. Extrapolating to the physical point gives m_pi a_3/2 = -0.0574 (+- 0.0016)(+0.0024 -0.0058) and m_pi a_1/2 = 0.1725 (+- 0.0017)(+0.0023 -0.0156) for the I=3/2 and I=1/2 scattering lengths, respectively, where the first error is statistical and the second error is an estimate of the systematic due to truncation of the chiral expansion.

description: We study the nonrelativistic limit of the quantum theory of a real scalar field with quartic self-interaction. The two body scattering amplitude is written in such way as to separate the contributions of high and low energy intermediary states. From this result and the two loop computation of the self energy correction, we determine an effective nonrelativistic action.

description: Artificial Intelligence is a central topic in the computer science curriculum. From the year 2011 a project-based learning methodology based on computer games has been designed and implemented into the intelligence artificial course at the University of the Bio-Bio. The project aims to develop software-controlled agents (bots) which are programmed by using heuristic algorithms seen during the course. This methodology allows us to obtain good learning results, however several challenges have been founded during its implementation. In this paper we show how linguistic descriptions of data can help to provide students and teachers with technical and personalized feedback about the learned algorithms. Algorithm behavior profile and a new Turing test for computer games bots based on linguistic modelling of complex phenomena are also proposed in order to deal with such challenges. In order to show and explore the possibilities of this new technology, a web platform has been designed and implemented by one of authors and its incorporation in the process of assessment allows us to improve the teaching learning process.

description: We investigate the spin Hall magnetoresistance in thin film bilayer heterostructures of the heavy metal Pt and the antiferromagnetic insulator NiO. While rotating an external magnetic field in the easy plane of NiO, we record the longitudinal and the transverse resistivity of the Pt layer and observe an amplitude modulation consistent with the spin Hall magnetoresistance. In comparison to Pt on collinear ferrimagnets, the modulation is phase shifted by 90° and its amplitude strongly increases with the magnitude of the magnetic field. We explain the observed magnetic field-dependence of the spin Hall magnetoresistance in a comprehensive model taking into account magnetic field induced modifications of the domain structure in antiferromagnets. With this generic model we are further able to estimate the strength of the magnetoelastic coupling in antiferromagnets. Our detailed study shows that the spin Hall magnetoresistance is a versatile tool to investigate the magnetic spin structure as well as magnetoelastic effects, even in antiferromagnetic multidomain materials.
