description: We show that the non-linear realisations of all the very extended algebras G^{+++}, except the B and C series which we do not consider, contain fields corresponding to all possible duality symmetries of the on-shell degrees of freedom of these theories. This result also holds for G_2^{+++} and we argue that the non-linear realisation of this algebra accounts precisely for the form fields present in the corresponding supersymmetric theory. We also find a simple necessary condition for the roots to belong to a G^{+++} algebra.

description: One of the main sources of error in multi-atlas segmentation propagation approaches comes from the use of atlas databases that are morphologically dissimilar to the target image. In this work, we exploit the segmentation errors associated with poor atlas selection to build a computer aided diagnosis (CAD) system for pathological classification in post-operative dextro-transposition of the great arteries (d-TGA). The proposed approach extracts a set of features, which describe the quality of a segmentation, and introduces them into a logical decision tree that provides the final diagnosis. We have validated our method on a set of 60 whole heart MR images containing healthy cases and two different forms of post-operative d-TGA. The reported overall CAD system accuracy was of 93.33%.

description: We calculate the rate of in-fall of stellar matter on an accretion disk during the collapse of a rapidly rotating massive star, and estimate the luminosity of the relativistic jet that results from accretion on to the central black hole. We find that the jet luminosity remains high for about 100 seconds, at a level comparable to the typical luminosity observed in gamma-ray bursts (GRBs). The luminosity then decreases rapidly with time for about 10^3 seconds, roughly as ~ t^-3; the duration depends on the size and rotation speed of the stellar core. The rapid decrease of the jet power explains the steeply declining X-ray flux observed at the end of most long duration GRBs. A X-ray plateau is also produced by continued fall-back of matter -- either from an extended stellar envelope or from material that failed to escape with the supernova ejecta. In a few GRBs, the X-ray light curve is observed to drop suddenly at the end of the plateau phase, while in others the decline is ~ t^-1 - t ^-2. These features arise naturally in the accretion model depending on the radius and mean specific angular momentum of the stellar envelope. The accretion model thus provides a coherent explanation for the diverse and puzzling features observed in the early X-ray light curves of GRBs. (Abridged)

description: Bayesian model selection enables comparison and ranking of conceptual subsurface models described by spatial prior models, according to the support provided by available geophysical data. Deep generative neural networks can efficiently encode such complex spatial priors, thereby, allowing for a strong model dimensionality reduction that comes at the price of enhanced non-linearity. In this setting, we explore a recent adaptive sequential Monte Carlo (ASMC) approach that builds on Annealed Importance Sampling (AIS); a method that provides both the posterior probability density function (PDF) and the evidence (a central quantity for Bayesian model selection) through a particle approximation. Both techniques are well suited to parallel computation and rely on importance sampling over a sequence of intermediate distributions, linking the prior and the posterior PDF. Each subsequent distribution is approximated by updating the particle weights and states, compared with the previous approximation, using a small pre-defined number of Markov chain Monte Carlo (MCMC) proposal steps. Compared with AIS, the ASMC method adaptively tunes the tempering between neighboring distributions and performs resampling of particles when the variance of the particle weights becomes too large. We evaluate ASMC using two different conceptual models and associated synthetic cross-hole ground penetrating radar (GPR) tomography data. For the most challenging test case, we find that the ASMC method is faster and more reliable in locating the posterior PDF than state-of-the-art adaptive MCMC. The evidence estimates are found to be robust with respect to the choice of ASMC algorithmic variables and much less sensitive to the model proposal type than MCMC.[...]

description: The four wavenumbers associated with planewave propagation in a Faraday chiral medium (FCM) with relatively huge magnetoelectric coupling give rise to enhanced possibilities for negative-phase-velocity propagation and therefore negative refraction. They can also give rise to the phenomenon of negative reflection. In particular, for a nondissipative example, we deduced that an incident plane wave with positive/negative phase velocity can result in a negatively reflected plane wave with negative/positive phase velocity, as well as a positively reflected plane wave with positive/negative phase velocity.

In such conditions, the collective of neuronal groups can reliably generate robust and flexible behavior, because it is known that at the critical point there is the largest abundance of metastable states to choose from. Here we review the motivation, arguments and recent results, as well as further implications of this view of the functioning brain.

description: The nature of Wireless Sensor Networks (WSN) and the widespread of using WSN introduce many security threats and attacks. An effective Intrusion Detection System (IDS) should be used to detect attacks. Detecting such an attack is challenging, especially the detection of Denial of Service (DoS) attacks. Machine learning classification techniques have been used as an approach for DoS detection. This paper conducted an experiment using Waikato Environment for Knowledge Analysis (WEKA)to evaluate the efficiency of five machine learning algorithms for detecting flooding, grayhole, blackhole, and scheduling at DoS attacks in WSNs. The evaluation is based on a dataset, called WSN-DS. The results showed that the random forest classifier outperforms the other classifiers with an accuracy of 99.72%.
From millennia to the millennium : an anthropological history of Bastar State
Creators: name: Huber, Walter Alexander
Publisher: name: University of British Columbia
Year: 2010

description: In this thesis I present an anthropological history of a remote and little-known area of India, the ex-Princely State of Bastar. While numerous ethnographic studies have been made of the predominantly tribal people of Bastar, there have been no attempts to contextualize properly the anthropology of what is now Bastar district. It is for this reason that an historical approach was chosen. This approach has led to the uncovering of a number of salient, anthropological problems: firstly, the identification of tribes in India, which process has engendered both definitional difficulties in the anthropology of India and less than felicitous behavioural consequences for those involved in the process itself; secondly, the nature of the political structure of Bastar State, leading to questions as to how it, and similar 'tribal' or 'Hindu-tribal' states of Middle India, came into being -- as well as an inquiry into the features which maintained Bastar's integrity; and lastly, a consideration, via a biographical account of the last king of Bastar, of the millenarian character of contemporary Bastar history and, in close relation, the problem of divine kingship. In response to the first problem I show that from an 'emic' perspective the term tribe is an incontestably valid and meaningful concept in understanding the majority of Bas-tar peoples. From an anthropologically objective point of view I take on the scholarly controversy of 'tribe' versus 'caste' in India in order to demonstrate that also on the level of disciplinary discussion the term 'tribe' has a meaningful place, at least in reference to Bastar. In regard to the second problem, i.e., of Bastar state formation, my description initially concentrates on the political aspects of the Hindu-tribal symbiosis, showing that the early Hindu (Kakatiya) monarchy of Bastar and the area's distinct tribal polity were nevertheless permutations of each other linked by weak central authority. This is followed by a cultural focus on Bastar divine kingship by which it is shown that the true integrity of the kingdom rested on a ritual plane. Extending the theme of divine kingship into modern times, the narrative of Bastar's last Maharaja details the confrontation of religious with secular power, and how the outcome of this confrontation led to a millenarian movement headed by a Hindu holy man believed to be the reincarnation of the last king. I conclude this thesis by drawing all these themes together, mainly in light of the writings of the doyen of Indian anthropology, Louis Dumont. With particular regard to his writings on Indian kingship and his theory of caste, I show the case of Bastar to be an important exception, and although not disproving Dumont's theories, I demonstrate the need for their modification. In the last analysis, the discussion in this thesis centres on divine kingship as a problem in the dualistic nature of power.

description: The frequencies of solar oscillations are known to change with solar activity. We use Principal Component Analysis to examine these changes with high precision. In addition to the well-documented changes in solar normal mode oscillations with activity as a function of frequency, which originate in the surface layers of the Sun, we find a small but statistically significant change in frequencies with an origin at and below the base of the convection zone. We find that at r=(0.712^{+0.0097}_{-0.0029})R_sun, the change in sound speed is δc^2 / c^2 = (7.23 +/- 2.08) x 10^{-5} between high and low activity. This change is very tightly correlated with solar activity. In addition, we use the splitting coefficients to examine the latitudinal structure of these changes. We find changes in sound speed correlated with surface activity for r >~ 0.9R_sun.

description: Star-forming galaxies (SFGs) emit non-thermal radiation from radio to gamma-rays. We aim to investigate the main mechanisms of global CR transport and cooling in SFGs. The way they contribute in shaping the relations between non-thermal luminosities and SFR could shed light onto their nature. We develop a model to compute the CR populations of SFGs, taking into account their production, transport, and cooling. The model is parameterised only through global galaxy properties, and describes the non-thermal emission in both radio and gamma-rays. We focus on the role of diffusive and advective transport by galactic winds, either driven by turbulent or thermal instabilities. We compare model predictions to observations, for which we compile a homogeneous set of luminosities in these radio bands, and update those available in gamma-rays. Our model reproduces reasonably well the observed relations between the gamma-ray or 1.4 GHz radio luminosities and the SFR, assuming a single power-law scaling of the magnetic field with the latter with index beta=0.3, and winds blowing either at Alfvenic speeds or typical starburst wind velocities. Escape of CR is negligible for > 30 Mo/yr. A constant ionisation fraction of the interstellar medium fails to reproduce the 150 MHz radio luminosity throughout the whole SFR range. Our results reinforce the idea that galaxies with high SFR are CR calorimeters, and that the main mechanism driving proton escape is diffusion, whereas electron escape also proceeds via wind advection. They also suggest that these winds should be CR or thermally-driven at low and intermediate SFR, respectively. Our results globally support that magnetohydrodynamic turbulence is responsible for the dependence of the magnetic field strength on the SFR and that the ionisation fraction is strongly disfavoured to be constant throughout the whole SFR range.

description: We investigate the behaviour of (p,q) string networks, focusing on two aspects: (1) modelling more realistic (p,q) string networks than the Z_N networks used so far and (2) investigating the effect of long-range interactions on the evolution of the network. We model the network with no long-range interactions using two sets of fields, complex scalars coupled to gauge fields, with a potential chosen such that the two types of strings will form bound states. This way we can model junctions of 3 strings with different tension; in Z_N models used so far in simulations all the strings have identical tensions. In order to introduce long-range interactions we also study a network in which one of the scalars forms global strings. We observe that in the absence of long-range interactions the formation of bound states has a significant influence on the evolution of the network. When long-range interactions are turned on the bound states are short-lived and have a minimal effect on the network evolution.

description: Nanophotonics is an important branch of modern optics dealing with light-matter interaction at the nanoscale. Nanoparticles can exhibit enhanced light absorption under illumination by light, and they become nanoscale sources of heat that can be precisely controlled and manipulated. For metal nanoparticles, such effects have been studied in the framework of $\textit{thermoplasmonics}$ which, similar to plasmonics itself, has a number of limitations. Recently emerged $\textit{all-dielectric resonant nanophotonics}$ is associated with optically-induced electric and magnetic Mie resonances, and this field is developing very rapidly in the last decade. As a result, thermoplasmonics is being replaced by $\textit{all-dielectric thermonanophotonics}$ with many important applications such as photothermal cancer therapy, drug and gene delivery, nanochemistry, and photothermal imaging. This review paper aims to introduce this new field of non-plasmonic nanophotonics and discuss associated thermally-induced processes at the nanoscale.

Saisei Itchi : the identity of religion and government in the early Meiji years 1867-1872
Creators: name: Brown, William Nimmo
Publisher: name: University of British Columbia
Year: 2010

description: This thesis is a study of the interaction of religion and government in the first five years of the Meiji Restoration (1868-1872). It deals with the ideological premises as well as the political application of Shinto as an organ of government. The paper discusses the elevation to national prominence of Shinto in the form of Restoration or Revival Shinto (Fukko Shintō) and traces both the theological antecedents as well as the ancient institutional origins of the religio-political theory of state espoused by the Restoration Shinto movement. This theory found political expression in the early Meiji years through the government's re-introduction and promotion of the religious policy of saisei itchi, the identity or unity of religion and government. This thesis has three main objectives: first, to examine the Shinto administrative mechanisms in the central government and thereby define saisei itchi as both an administrative structure and a religio-political ideology; second, to investigate the practical application of, saisei itchi as a religious policy by looking at the legislation effected by Shinto administrative bodies; and third, to define the position and role of the saisei itchi construct within the context of the general pre-war alliance of Shinto and the Japanese state which is categorized under the blanket term State Shinto (Kokka Shintō). This thesis concludes that the implementation of saisei itchi was a consistent goal of the early Meiji government between 1868 and 1872. The promotion of the Restoration Shinto ideology expressed through the saisei itchi ideal provided an ideological framework which aided in the consolidation of Shinto as a religious structure and in the acceptance of the new Imperial government. The paper argues further that saisei itchi was to a significant degree religious in intent, so much so that it can be viewed as being a distinct entity within the general context of State Shinto with which it is usually fused or confused. That is, in the work of several modern historians, saisei itchi has either been treated as an integral component of State Shinto or mistaken for State Shinto itself. By highlighting saisei itchi as the major facet in the early Meiji state's involvement with Shinto, this thesis hopes to provide some insight into this oft neglected aspect of early Meiji government.

description: In this paper we deal with production situations where a cap or limit to the amount of greenhouse gas emissions permitted is imposed. Fixing a tax for each ton of pollutant emitted is also considered. We use bankruptcy rules to define cooperative games with externalities associated with these situations and analyze the existence of coalitionally stable allocations of the emission permits. We prove that the constrained equal awards ( CEA ) rule provides stable allocations and as a direct mechanism, it is incentive compatible. These two facts have interesting managerial implications to control pollution emissions.
Wilson-t'Hooft Loops in Finite-Temperature Non-commutative Dipole Field Theory from Dual Supergravity

Year: 2007
Subjects: subject: High Energy Physics - Theory (hep-th)

description: We first study the temporal Wilson loop in the finite-temperature non-commutative dipole field theory from the string/gauge correspondence. The associated dual supergravity background is constructed from the near-horizon geometry of near-extremal D-branes, after applying T-duality and smeared twist. We investigate the string configuration therein and find that while the temperature produces a maximum distance $L_{max}$ in the interquark distance the dipole in there could produce a minimum distance $L_{min}$. The quark boundary pair therefore could be found only if their distance is between $L_{min}$ and $L_{max}$. We also show that, beyond a critical temperature the quark pair becomes totally free due to screening by thermal bath. We next study the spatial Wilson loop and find the confining nature in the zero temperature 3D and 4D non-supersymmetry dipole gauge theory. The string tension of the linear confinement potential is obtained and found to be a decreasing function of the dipole field. We also investigate the associated t'Hooft loop and determine the corresponding monopole anti-monopole potential. The conventional screening of magnetic charge which indicates the confinement of the electric charge is replaced by a strong repulsive however. Finally, we show that the dual string which is rotating along the dipole deformed $S^5$ will behave as a static one without dipole field, which has no minimum distance and has larger energy than a static one with dipole field. We discuss the phase transition between these string solutions.

description: In this paper, we examine the evolution of a specific mathematical problem, i.e. the nine-point conic, a generalisation of the nine-point circle due to Steiner. We will follow this evolution from Steiner to the Neapolitan school (Trudi and Battaglini) and finally to the contribution of Beltrami that closed this journey, at least from a mathematical point of view (scholars of elementary geometry, in fact, will continue to resume the problem from the second half of the 19th to the beginning of the 20th century). We believe that such evolution may indicate the steady development of the mathematical methods from Euclidean metric to projective, and finally, with Beltrami, with the use of quadratic transformations. In this sense, the work of Beltrami appears similar to the recent (after the anticipations of Magnus and Steiner) results of Schiaparelli and Cremona. Moreover, Beltrami's methods are closely related to the study of birational transformations, which in the same period were becoming one of the main topics of algebraic geometry. Finally, our work emphasises the role played by the ninepoint conic problem in the studies of young Beltrami who, under Cremona's guidance, was then developing his mathematical skills. To this end, we make considerable use of the unedited correspondence Beltrami-Cremona, preserved in the Istituto Mazziniano, Genoa.
Determinants of audit quality: evidence from China

description: This thesis consists of three separate research projects on auditing issues, including auditor switch, audit fees, and audit quality. 
The first study exploits the unique setting of China’s audit price deregulation in 2014 to examine the effect of audit firm characteristics on audit switches. I find a significant increase in audit firm-client realignments after the audit price deregulation policy was implemented. I also find that the increase in realignment is mainly driven by audit firms achieving economies of scale (EOS), suggesting that the efficient cost structure of audit firms provides an important advantage when competing for new clients. These main results are robust to alternative definitions of EOS. Additional analysis shows that, compared to non-EOS audit firms, EOS audit firms are more likely to offer audit fee discounts without compromising the audit quality. I also find that the EOS effect is more pronounced for auditors in highly homogenous industries. Overall, the results of this study provide important insights to policymakers and regulators not only in China but also in other countries when revisiting or developing new audit services policies. 
The second study examines whether the impact of a client firm’s environmental penalty on the cost of audit services differs between female and male auditors in China. I find that the audit fee increase is more pronounced for female auditors than male auditors when a firm incurs an environmental penalty. I also observe that the results are more pronounced for penalized firms that: (i) do not disclose any corporate social responsibility related deficiencies (ii) do not report any internal control weaknesses, (iii) are located in high legal indexed Chinese regions, and (iv) are in less polluting industries. I show that female auditors consider a client’s environmental penalty as an indicator of potential risks. Taken together, these findings confirm the importance of the “gender effect” on a client firm’s audit fees as a consequence of environmental misconduct. 
The third study exploits the unique setting of the 2018 US-China trade war to examine the impact of tariff absorption on audit fee cuts and audit quality for both US and Chinese firms. Following the US tariff increases, I find a significant decrease in profitability for both affected Chinese and US firms, indicating that the increased tariff costs are shared by firms at both ends of the US-China supply chain. Furthermore, I find that the decline in profitability results in a cut in audit fees which in turn has a significantly negative impact on audit quality for Chinese firms but not for US firms. Together, the findings suggest that “tariff absorption” could have a significant influence on firms’ audit fees and audit quality, conditional on the different legal regimes.

description: The Hamiltonian Mean-Field model has been investigated, since its introduction about a decade ago, to study the equilibrium and dynamical properties of long-range interacting systems. Here we study the long-time behavior of long-lived, out-of-equilibrium, quasi-stationary dynamical states, whose lifetime diverges in the thermodynamic limit. The nature of these states has been the object of a lively debate, in the recent past. We introduce a new numerical tool, based on the fluctuations of the phase of the instantaneous magnetization of the system. Using this tool, we study the quasi-stationary states that arise when the system is started from different classes of initial conditions, showing that the new observable can be exploited to compute the lifetime of these states. We also show that quasi-stationary states are present not only below, but also above the critical temperature of the second order magnetic phase transition of the model. We find that at supercritical temperatures the lifetime is much larger than at subcritical temperatures.

description: Clusters of galaxies are the most impressive gravitationally-bound systems in the Universe and its abundance (the cluster mass function) is one important statistics to probe the matter density parameter ($Ω_m$) and the amplitude of density fluctuations ($σ_8$). The cluster mass function is usually described in terms of the Press-Schecther (PS) formalism where the primordial density fluctuations are assumed to be a Gaussian random field. In previous works we have proposed a non-Gaussian analytical extension of the PS approach with basis on the $q$-power law distribution (PL) of the non-extensive kinetic theory. In this paper, by applying the PL distribution to fit the observational mass function data from X-ray highest flux-limited sample (HIFLUGCS) we find a strong degeneracy among the cosmic parameters, $σ_8$, $Ω_m$, and the $q$ parameter from the PL distribution. A joint analysis involving recent observations from baryon acoustic oscillation (BAO) peak and Cosmic Microwave Background (CMB) shift parameter is carried out in order to break these degeneracy and better constrain the physically relevant parameters. The present results suggest that the next generation of cluster surveys will be able to probe the quantities of cosmological interest ($σ_8, Ω_m$) and the underlying cluster physics quantified by the $q$-parameter.

description: We quantify the extent to which future experiments will test the existence of neutrinoless double-beta decay mediated by light neutrinos with inverted-ordered masses. While it remains difficult to compare measurements performed with different isotopes, we find that future searches will fully test the inverted ordering scenario, as a global, multi-isotope endeavor. They will also test other possible mechanisms driving the decay, including a large uncharted region of the allowed parameter space assuming that neutrino masses follow the normal ordering.

description: Coupled states of semiconductor quantum well (QW) excitons and photons in a two dimensional (2D) periodic lattice of microcavities are analyzed theoretically, revealing allowed bands and forbidden gaps in the energy spectrum of exciton polaritons. Photonic crystal exciton polaritons have spatially uniform excitonic constituent set by flat QWs, but exhibit periodic Bloch oscillations in the plane of QWs due to their photonic component. The envelope functions of photonic crystal exciton polaritons can be tailored via effective potential of a photonic crystal heterostructure, by using quasi-periodic lattices of microcavities. Confined envelope function states of lower and upper polaritons and the Bose-Einstein condensation of lower polaritons are analyzed here in a photonic crystal heterostructure trap with harmonic oscillator potential. This concept is numerically illustrated on example of CdTe/CdMgTe microcavities.

description: A critical step in topology optimization (TO) is finding sensitivities. Manual derivation and implementation of the sensitivities can be quite laborious and error-prone, especially for non-trivial objectives, constraints and material models. An alternate approach is to utilize automatic differentiation (AD). While AD has been around for decades, and has also been applied in TO, wider adoption has largely been absent. In this educational paper, we aim to reintroduce AD for TO, and make it easily accessible through illustrative codes. In particular, we employ JAX, a high-performance Python library for automatically computing sensitivities from a user defined TO problem. The resulting framework, referred to here as AuTO, is illustrated through several examples in compliance minimization, compliant mechanism design and microstructural design.

description: Glioblastoma (GBM) is a highly morbid and lethal disease with poor prognosis. Their emergent properties such as cellular heterogeneity, therapy resistance, and self-renewal are largely attributed to the interactions between a subset of their population known as glioblastoma-derived stem cells (GSCs) and their microenvironment. Identifying causal patterns in the developmental trajectories between GSCs and the mature, well-differentiated GBM phenotypes remains a challenging problem in oncology. The paper presents a blueprint of complex systems approaches to infer attractor dynamics from the single-cell gene expression datasets of pediatric GBM and adult GSCs. These algorithms include Waddington landscape reconstruction, Generative Adversarial Networks, and fractal dimension analysis. Here I show, a Rossler-like strange attractor with a fractal dimension of roughly 1.7 emerged in the GAN-reconstructed patterns of all twelve patients. The findings suggest a strange attractor may be driving the complex dynamics and adaptive behaviors of GBM in signaling state-space.

description: Big Data analytics supported by AI algorithms can support skills localization and retrieval in the context of a labor market intelligence problem. We formulate and solve this problem through specific DataOps models, blending data sources from administrative and technical partners in several countries into cooperation, creating shared knowledge to support policy and decision-making. We then focus on the critical task of skills extraction from resumes and vacancies featuring state-of-the-art machine learning models. We showcase preliminary results with applied machine learning on real data from the employment agencies of the Netherlands and the Flemish region in Belgium. The final goal is to match these skills to standard ontologies of skills, jobs and occupations.

description: We determine some basic properties of stars that produce spectacular gamma-ray bursts at the end of their life. We assume that accretion of the outer portion of the stellar core by a central black hole fuels the prompt emission, and that fall-back and accretion of the stellar envelope later produces the plateau in the X-ray light curve seen in some bursts. Using X-ray data for three bursts we estimate the radius of the stellar core to be ~ 1-3 x 10^10 cm, and that of the stellar envelope to be ~ 1-2 x 10^11 cm. The density profile in the envelope is fairly shallow, with ρ~ r^-2. The rotation speeds of the core and envelope are ~ 0.05 and ~ 0.2 of the local Keplerian speed, respectively.

description: Noiseless optical components are critical for applications ranging from metrology to quantum communication. Here we characterize several commercial telecom C-band fiber components for parasitic noise using a tunable laser. We observe the spectral signature of trace concentrations of erbium in all devices from the underlying optical crystals including YVO4, LiNbO3, TeO2 and AMTIR glass. Due to the long erbium lifetime, these signals are challenging to mitigate at the single photon level in the telecom range, and suggests the need for higher purity optical crystals.

description: This is the fifth paper in a series aimed at studying the chromospheres of active binary systems using several optical spectroscopic indicators to obtain or improve orbital solution and fundamental stellar parameters. We present here the study of FF UMa (2RE J0933+624), a recently discovered, X-ray/EUV selected, active binary with strong H_alpha emission. The objectives of this work are, to find orbital solutions and define stellar parameters from precise radial velocities and carry out an extensive study of the optical indicators of chromospheric activity. We obtained high resolution echelle spectroscopic observations during five observing runs from 1998 to 2004. We found radial velocities by cross correlation with radial velocity standard stars to achieve the best orbital solution. We also measured rotational velocity by cross-correlation techniques and have studied the kinematic by galactic space- velocity components (U, V, W) and Eggen criteria. Finally, we have determined the chromospheric contribution in optical spectroscopic indicators, from Ca II H & K to Ca II IRT lines, using the spectral subtraction technique. We have found that this system presents an orbital period variation, higher than previously detected in other RS CVn systems. We determined an improved orbital solution, finding a circular orbit with a period of 3.274 days. We derived the stellar parameters, confirming the subgiant nature of the primary component and obtained rotational velocities (vsini), of 33.57 km/s and 32.38 km/s for the primary and secondary components respectively. From our kinematic study, we can deduce its membership to the Castor moving group. Finally, the activity study has given us a better understanding of the possible mechanisms that produce the orbital period variation.
