description: We study the dynamics of gene activities in relatively small size biological networks (up to a few tens of nodes), e.g. the activities of cell-cycle proteins during the mitotic cell-cycle progression. Using the framework of deterministic discrete dynamical models, we characterize the dynamical modifications in response to structural perturbations in the network connectivities. In particular, we focus on how perturbations affect the set of fixed points and sizes of the basins of attraction. Our approach uses two analytical measures: the basin entropy $H$ and the perturbation size $Δ$, a quantity that reflects the distance between the set of fixed points of the perturbed network to that of the unperturbed network. Applying our approach to the yeast-cell cycle network introduced by Li \textit{et al.} provides a low dimensional and informative fingerprint of network behavior under large classes of perturbations. We identify interactions that are crucial for proper network function, and also pinpoints functionally redundant network connections. Selected perturbations exemplify the breadth of dynamical responses in this cell-cycle model.

description: We study the isotope effects arising from the coupling of correlated electrons with dispersionless phonons by considering the Hubbard-Holstein model at half-filling within the dynamical mean-field theory. In particular we calculate the isotope effects on the quasi-particle spectral weight $Z$, the renormalized phonon frequency, and the static charge and spin susceptibilities. In the weakly correlated regime $U/t \lesssim 1.5$, where $U$ is the Hubbard repulsion and $t$ is the bare electron half-bandwidth, the physical properties are qualitatively similar to those characterizing the Holstein model in the absence of Coulomb repulsion, where the bipolaronic binding takes place at large electron-phonon coupling, and it reflects in divergent isotope responses. On the contrary in the strongly correlated regime $U/t \gtrsim 1.5$, where the bipolaronic metal-insulator transition becomes of first order, the isotope effects are bounded, suggesting that the first order transition is likely driven by an electronic mechanism, rather then by a lattice instability. These results point out how the isotope responses are extremely sensitive to phase boundaries and they may be used to characterize the competition between the electron-phonon coupling and the Hubbard repulsion.

description: Epitaxial thin films of multiferroic perovskite BiMnO3 were synthesized on SrTiO3 substrates, and orbital ordering and magnetic properties of the thin films were investigated. The ordering of the Mn^{3+} e_g orbitals at a wave vector (1/4 1/4 1/4) was detected by Mn K-edge resonant x-ray scattering. This peculiar orbital order inherently contains magnetic frustration. While bulk BiMnO3 is known to exhibit simple ferromagnetism, the frustration enhanced by in-plane compressive strains in the films brings about cluster-glass-like properties.

description: Generalizability of machine-learning (ML) based turbulence closures to accurately predict unseen practical flows remains an important challenge. At the Reynolds-averaged Navier-Stokes (RANS) level, NN-based turbulence closure modeling is rendered difficult due to two important reasons: inherent complexity of the constitutive relation arising from flow-dependent non-linearity and bifurcations; and, inordinate difficulty in obtaining high-fidelity data covering the entire parameter space of interest. In this context, the objective of the work is to investigate the approximation capabilities of standard moderate-sized fully-connected NNs. We seek to systematically investigate the effects of: (i) intrinsic complexity of the solution manifold; (ii) sampling procedure (interpolation vs. extrapolation) and (iii) optimization procedure. To overcome the data acquisition challenges, three proxy-physics turbulence surrogates of different degrees of complexity (yet significantly simpler than turbulence physics) are employed to generate the parameter-to-solution maps. Even for this simple proxy-physics system, it is demonstrated that feed-forward NNs require more degrees of freedom than the original proxy-physics model to accurately approximate the true model even when trained with data over the entire parameter space (interpolation). Additionally, if deep fully-connected NNs are trained with data only from part of the parameter space (extrapolation), their approximation capability reduces considerably and it is not straightforward to find an optimal architecture. Overall, the findings provide a realistic perspective on the utility of ML turbulence closures for practical applications and identify areas for improvement.
Colonizing masculinity : the creation of a male British subjectivity in the oriental fiction of W. Somerset Maugham
Creators: name: Holden, Philip Joseph
Publisher: name: University of British Columbia
Year: 2009

description: This thesis discusses the oriental fiction of W. Somerset Maugham in the light of current theoretical models introduced by postcolonial and gender studies. Immensely popular from their time of publication to the present, Maugham's novels and short stories set in Asia and the South Pacific exhibit a consummate recycling of colonialist tropes. Through their manipulation of racial, gender, and geographical binarisms, Maugham's texts produce a fantasy of a seemingly stable British male subjectivity based upon emotional and somatic continence, rationality, and specularity. The status of the British male subject is tested and confirmed by his activity in the colonies. Maugham's situation of writing as a homosexual man, however, results in affiliations which cut across the binary oppositions which structure Maugham's texts, destabilising the integrity of the subject they strive so assiduously to create. Commencing with Maugham's novel The Moon and Sixpence, and his short story collection The Trembling of a Leaf, both of which are set in the South Pacific, the thesis moves to a discussion of Maugham's Chinese travelogue, On a Chinese Screen, and his Hong Kong novel, The Painted Veil. Further chapters explore the Malayan short stories, and Maugham's novel set in the then Dutch East Indies, The Narrow Corner. A final chapter discusses Maugham's novel of India, The Razor's Edge. Unlike many of his contemporaries, Maugham does not even attempt a liberal critique of British Imperialism. Writing and narration are, for him, processes closely identified with codes of imperial manliness. Maugham's putatively objective narrators, and the public "Maugham persona" which the writer carefully cultivated, display a strong investment in the British male subjectivity outlined above. Yet Maugham's texts also endlessly discover writing as a play of signification, of decoration, of qualities that he explicitly associates in other texts with homosexuality. If Maugham's texts do not critique the formation of colonial subjects they do, to a critical reader, make the rhetoric necessary to create such subjects peculiarly visible.
Using globular clusters to test gravity in the weak acceleration regime: NGC 7099

description: A test of Newton's law of gravity in the low acceleration regime using globular clusters is presented. New results for the core collapsed globular cluster NGC 7099 are given. The run of the gravitational potential as a function of distance is probed studying the velocity dispersion profile of the cluster, as derived from a set of 125 radial velocities with accuracy better than 1 km/s. The velocity dispersion profile is traced up to ~18 pc from the cluster center. The dispersion is found to be maximal at the center, then decrease until 10+-2 pc from the center, well inside the cluster tidal radius of 42 pc. After that the dispersion remains constant with average value 2.2+-0.3 km/s. Assuming for NGC 7099 a total V mag of M(V)=-7.43 mags and mass-to-light ratio M/L=1, the acceleration at 10 pc from the center is 1.1e-8 cm/s/s. Thus, the flattening of the velocity dispersion profile occurs for a value of the internal acceleration of gravity fully consistent with a_0=1.2e-8 cm/s/s observed in galaxies. This new result for NGC 7099 brings to 4 the clusters with velocity dispersion profile probing acceleration below a_0. All four have been found to have a flat dispersion profile at large radii where the acceleration is below a_0, mimicking qualitatively and quantitatively elliptical galaxies. Whether this indicates a failure of Newtonian dynamics in the low acceleration limit or some more conventional dynamical effect (e.g., tidal heating) is still unclear. However, the similarities emerging between very different globular clusters, as well as between globular clusters and elliptical galaxies seem to favor the first of these two possibilities.

M-dwarfs

description: Superflares (flares with energy 10^33 erg or greater) provide the dominant source of biologically-relevant UV radiation to rocky planets in M-dwarf habitable zones, altering planetary atmospheres and conditions for prebiotic chemistry and surface life. However, the temperature and therefore UV emission of these rare events is not well constrained. Dozens of M-dwarf superflares were observed simultaneously by Evryscope and TESS as part of the EvryFlare Survey, comprising the first-ever statistical sample of M-dwarf superflares with optical temperatures measured at 2 minute cadence. I present newly-discovered scaling laws between superflare temperatures, energies, and heating environments. Because the blackbody extends well into the UV, I estimate UV-B and UV-C fluxes from the optical by fitting blackbody temperatures to the multi-wavelength flare observations. While flares are often assumed to emit at 9000 K, my survey finds nearly half of M-dwarf superflares emit at temperatures above 14,000 K. The largest and hottest flare in the sample reached 42,000 K. If these colors truly represent the continuum, they suggest that predictions of the UV emission from the optical using a canonical 9000 K blackbody are under-estimating the true emission by up to an order of magnitude. My survey finds rocky planets orbiting in the habitable zones of <200 Myr M-dwarfs receive top-of-atmosphere UV-C fluxes up to 1000 W m^-2, significantly impacting planetary atmospheres.

Spitzer IRAC Photometry of K Giants Used as Spectro-Photometric Standards for IRS

description: We used Spitzer's IRAC at 3.6 and 4.5 um to observe 36 K giants which were spectro-photometric standard stars for Spitzer's IRS. To compare the data from IRAC and the IRS, we generate synthetic photometry from ISO/SWS-based spectral templates to bridge the gap between the end of the spectra and the photometric bands. We applied two methods for selecting templates, both of which confirmed a match of ~1% between the observed and synthetic photometry at 3.6 um. Choosing the templates based on the optical-NIR photometry and effective temperature of the star produced a match of <1% at 4.5 um, with small but noticeable discrepancies in the 8 um SiO absorption band for some stars. Choosing the templates to match the 8 um band in the IRS data required somewhat higher temperatures and showed a weak temperature dependence for the 4.5 um photometric ratios. Thus, we were unable to simultaneously fit both the SiO absorption band at 8 um and the IRAC photometry at 4.5 um with the templates. The discrepancy at 4.5 um was small, less than 2%, but this result points to the continued challenge of using K giants as spectro-photometric standards.

description: The signatures of CNONa-bearing molecules in the atmospheres of red giant stars can be used to identify and characterize multiple stellar populations in globular clusters. Abundance studies over the last two decades have revealed Na-O, Mg-Al, and other anticorrelations among globular cluster red giant stars that are commonly interpreted as evidence of two or more episodes of star formation. Meanwhile, photometric studies have shown that CNONa abundance variations in cluster red giants can be detected using blue and NUV filters because various strong molecular absorption bands (OH, CN, NH, CH) are found blueward of ~4000 Å. We present the photometric detection of multiple RGB sequences in 14 Milky Way bulge globular clusters, which demonstrates the efficacy of ground-based de-reddened optical SDSS ugriz photometry, and in particular the (u-g)-(g-i) (Cugi) pseudo-color index, to separate giant stars with varying atmospheric light element abundances, even when the clusters are heavily obscured. We find that the spread in Cugi colors of the red giant stars correlates with their CNONa atmospheric abundances, and that the derived stellar population fraction of each cluster is correlated with the cluster absolute visual magnitude, in agreement with recent HST photometric studies of halo globular clusters.

description: For rare events described in terms of Markov processes, truly unbiased estimation of the rare event probability generally requires the avoidance of numerical approximations of the Markov process. Recent work in the exact and $\varepsilon$-strong simulation of diffusions, which can be used to almost surely constrain sample paths to a given tolerance, suggests one way to do this. We specify how such algorithms can be combined with the classical multilevel splitting method for rare event simulation. This provides unbiased estimations of the probability in question. We discuss the practical feasibility of the algorithm with reference to existing $\varepsilon$-strong methods and provide proof-of-concept numerical examples.

‘I’ve been nowhere and done nothing’. The characterization of Daisy Mason in the British drama Downton Abbey
Creators: name: Lazzeretti, Cecilia

Subjects: characterization; television series; Downton Abbey; corpus linguistics; identity; language

description: The article aims at investigating the characterization of Daisy Mason in the British television drama Downton Abbey and is based on a corpus of transcripts of episodes in Series One, Two and Three. The relevant background of the study is represented by Culpeper’s (2001) and Bednarek’s studies on characterization in drama and fictional television (Bednarek 2010, 2011a, 2011b, 2011c, 2012). Drawing upon a combined methodology, in line with the Corpus Assisted Discourse Studies tradition (Partington, Duguid and Taylor 2013), the analysis puts in relation the most relevant aspects of the personality of Daisy – the character traits obtained by applying Culpeper’s (2001) framework on textual cues – with typical features of her speech revealed by corpus linguistics methodologies. Corpus evidence shows a relevant presence of negatives in Daisy’s speech: I don’t know is the most frequent three-word cluster around the pronoun I. Her sentences are shorter than the average of other characters and are often self-interrupted. Moreover, she asks a question every fourth sentence, while the average of other characters is one every fifth. Results point to a frustrated character, a silent rebellious who has difficulties in expressing her thoughts and does not accept to play a minor role in the story.

description: Recently, a holographic argument was used to relate the saturation exponent, $γ_{BFKL}$, of four-dimensional Yang-Mills theory in the Regge limit to the Choptuik critical scaling exponent, $γ_{5d}$, in 5-dimensional black hole formation via scalar field collapse \cite{alvarez-gaume}. Remarkably, the numerical value of the former agreed quite well with previous calculations of the latter. We present new results of an improved calculation of $γ_{5d}$ with substantially decreased numerical error. Our current result is $γ_{5d} = 0.4131 \pm 0.0001$, which is close to, but not in strict agreement with, the value of $γ_{BFKL}=0.409552$ quoted in \cite{alvarez-gaume}.

description: Scene segmentation of a video, a book or TV series allows to organize them into Logical Story Units and is an essential step for representing, extracting and understanding their narrative structures. We propose an automatic scene segmentation method for TV series based on the grouping of adjacent shots and relying on a combination of multimodal neural features: visual features and textual features, further augmented with the temporal information which may improve the clustering of adjacent shots. Reported experiments compare early and late fusion of the features, video frames subsampling and various shot clustering algorithms. The proposed method achieved good recall, precision and F-measure when tested on several seasons of two popular TV series.

description: A central goal of condensed-matter physics is to understand how the diverse electronic and optical properties of crystalline materials emerge from the wavelike motion of electrons through periodically arranged atoms. However, more than 90 years after Bloch derived the functional forms of electronic waves in crystals [1] (now known as Bloch wavefunctions), rapid scattering processes have so far prevented their direct experimental reconstruction. In high-order sideband generation [2-9], electrons and holes generated in semiconductors by a near-infrared laser are accelerated to a high kinetic energy by a strong terahertz field, and recollide to emit near-infrared sidebands before they are scattered. Here we reconstruct the Bloch wavefunctions of two types of hole in gallium arsenide at wavelengths much longer than the spacing between atoms by experimentally measuring sideband polarizations and introducing an elegant theory that ties those polarizations to quantum interference between different recollision pathways. These Bloch wavefunctions are compactly visualized on the surface of a sphere. High-order sideband generation can, in principle, be observed from any direct-gap semiconductor or insulator. We thus expect that the method introduced here can be used to reconstruct low-energy Bloch wavefunctions in many of these materials, enabling important insights into the origin and engineering of the electronic and optical properties of condensed matter.

description: We give a simple order-theoretic construction of a Cartesian closed category of sequential functions. It is based on bistable biorders, which are sets with a partial order -- the extensional order -- and a bistable coherence, which captures equivalence of program behaviour, up to permutation of top (error) and bottom (divergence). We show that monotone and bistable functions (which are required to preserve bistably bounded meets and joins) are strongly sequential, and use this fact to prove universality results for the bistable biorder semantics of the simply-typed lambda-calculus (with atomic constants), and an extension with arithmetic and recursion. We also construct a bistable model of SPCF, a higher-order functional programming language with non-local control. We use our universality result for the lambda-calculus to show that the semantics of SPCF is fully abstract. We then establish a direct correspondence between bistable functions and sequential algorithms by showing that sequential data structures give rise to bistable biorders, and that each bistable function between such biorders is computed by a sequential algorithm.

Ensemble multiple sequence alignment via advising

Publisher: name: F1000Research
Year: 2015

description: The multiple sequence alignments computed by an aligner for different settings of its parameters, as well as the alignments computed by different aligners using their default settings, can differ markedly. Parameter advising is the task of choosing a parameter setting for an aligner that maximizes the accuracy of the resulting alignment. We extend parameter advising to aligner advising, which chooses among a set of aligners to maximize accuracy. In the context of aligner advising, default advising selects from a set of aligners that are using their default settings, while general advising chooses both the aligner and its parameter setting.

In this paper, we apply aligner advising for the first time, to obtain a true ensemble aligner. Through experiments on benchmark protein sequence alignments, we show that parameter advising for a fixed aligner gives a significant boost in accuracy over simply using its default setting, for all of the most accurate aligners currently used in practice. Furthermore, for ensemble alignment, default aligner advising gives a further boost in accuracy over parameter advising for any single aligner, and general aligner advising improves beyond default advising. Our new ensemble aligner that results from general aligner advising, when evaluated on standard suites of protein alignment benchmarks, and selecting from a set of 4 or more choices, is 4 percent more accurate than the best single default aligner. This is the first successful demonstration of how to construct from a collection of aligners, a new, more powerful aligner.

Order and organization in lodgepole pine forests of West-Central British Columbia
Creators: name: Brulisauer, Alfred Robert
Publisher: name: University of British Columbia
Year: 2009

description: Trends of temporal development were documented for lodgepole pine-dominated forest communities recovering after fire disturbance in the interior of British Columbia. Order and organization within these communities, considered to be key indicators of the recovery process, were quantified by means of equal frequency ellipses in multivariate space and angular comparisons between eigenvectors. Estimates of ecological order were also based on more traditional methods such as Shannon diversity and spatial heterogeneity. Observed trends were evaluated in light of recent attempts to interpret development in the living world as resulting from energetic dynamics in non-equilibrium systems. Of particular interest were phenomenological similarities between successional and organismic development as predicted from an interpretation of succession as a developmental process. In addition, implications of the results to questions of diversity and stability and their mutual relationship in ecological systems were also explored. Similarities were evaluated between successional and organismic development according to four phenomenological rules (Weber et al. 1989, Salthe 1991) . Succession in the investigated communities appeared to follow similar trends as found in organismic development in terms of energetic efficiency, structural complexity, speed and course of development and system stability. The undivided data (xeric and mesic stands combined) suggested a steady decrease in diversity up to a penultimate phase with a subsequent increase as climax was approached. Eccentricity of the equal frequency ellipses, interpreted to be an indicator of redundant system configurations, followed a similar pattern, thereby behaving in agreement with expectations from Prigogine’s minimum dissipation principle predicting a system to sacrifice multiple pathways in exchange for higher energetic efficiency. Order, quantified based on species data, was found to remain relatively stable during succession. Organizational dynamics were most pronounced at the onset of succession and slowed down with increasing stand age. Stability and resilience were found to be lower on sites of poor environmental conditions than on mesic sites. No relationship, however, of stability or resilience with diversity could be established as levels of diversity in both mesic and xeric sites were similar. Lower redundancy on xeric sites was interpreted as an indicator for lower stability, leading to higher sensitivity to environmental fluctuations during the process of recovery. It was found that processes in successional and organismic development were reasonably similar except for sites in unproductive locations. This was interpreted to be a result of the lower degree of integration of such sites. Thus, the investigated communities appeared to exhibit patterns similar to organismic development if autogenic processes were able to proceed relatively undisturbed.

description: The identification of solar coronal holes (CHs) observed in Extreme Ultraviolet (EUV) intensity images of the Sun is key in improving our understanding of their association with solar magnetic fields and heliophysics. In particular, CHs at the poles of the Sun are a notorious source of fast solar wind and thus warrant further study, most notably in the context of space-weather forecasting. This has consequently led to the development of various segmentation methods for their identification, including supervised machine learning. We introduce the SEARCH project to combine EUV data from the three vantage points (e.g., STEREO-A, STEREO-B, and SoHO) during the 2010-2014 epoch to produce synchronic maps and apply unsupervised learning methods including clustering and convolutional neural networks for the segmentation of CHs. SEARCH segmentation maps provide a venue to explore the relationship between CH pole areas, geomagnetic activity, and the magnetic activity cycle (dynamo process) of the Sun and Sun-like stars. Finally, in addition to CHs, the unsupervised learning methods we tested identified features consistent with active regions.

Variational Principle for Stochastic Mechanics Based on Information Measures
Creators: name: Yang, Jianhao M.
Publisher: name: arXiv
Year: 2021
Subjects: subject: Quantum Physics (quant-ph)
subject: FOS: Physical sciences

description: Stochastic mechanics is regarded as a physical theory to explain quantum mechanics with classical terms such that some of the quantum mechanics paradoxes can be avoided. Here we propose a new variational principle to uncover more insights on stochastic mechanics. According to this principle, information measures, such as relative entropy and Fisher information, are imposed as constraints on top of the least action principle. This principle not only recovers Nelson's theory and consequently, the Schrödinger equation, but also clears an unresolved issue in stochastic mechanics on why multiple Lagrangians can be used in the variational method and yield the same theory. The concept of forward and backward paths provides an intuitive physical picture for stochastic mechanics. Each path configuration is considered as a degree of freedom and has its own law of dynamics. Thus, the variation principle proposed here can be a new tool to derive more advanced stochastic theory by including additional degrees of freedom in the theory. The structure of Lagrangian developed here shows that some terms in the Lagrangian are originated from information constraints. This suggests a Lagrangian may need to include both physical and informational terms in order to have a complete description of the dynamics of a physical system.

Effect of pH-induced conformational changes of UreI transporter from Helicobacter pylori

description: Helicobacter pylori is an important factor in the development of gastroduodenal disease such as acute/chronic gastritis, duodenal ulcer and gastric cancer. The failed attempt of current eradication therapies and the increase of resistant strains makes urgent the search of new pharmacological agents. The relevance of protein – protein interactions in different biological pathways makes them an attractive therapeutic target. We have performed molecular dynamics simulations at distinct pH conditions (pH 2.0, 6.1 and 7.4) of the UreI transporter. We had observed that most of the changes concentrate in the periplasmic regions. Moreover, new interactions appear in the contact residues of the interface between subunits of the UreI complex upon pH changes, relating them with the observable changes in the periplasmic loops. Steered molecular dynamics simulations of two subunit of the UreI complex at pH 2.0 and 6.1 shows differences in the uncoupling pathway, in relation to the needed force to disrupt its interactions. Finally, the changes in the interface given the simulated pH affects in some manner the prediction of the docked position of different small organic molecules.
An Introduction to Network Analysis for Television Studies: Visual Models and Practical Applications

description: With the advent of open-source digital tools, abstract models have been consistently adopted in humanistic research and they have proven to be useful for many purposes: for predictive and descriptive analysis using quantitative or qualitative models, for database management, as in the case of relational models, and for modeling cultural dynamics (Gabor 2008). Among others, television scholars embraced such a trend in cultural analytics and digital humanities, by notably adopting modeling practices for assessing viewers behaviors (Wonneberger 2009) or for measuring qualitative variations in narrative ecosystems (Pescatore, Rocchi 2018). Drawing upon this digital turn, the following paper aims to discuss the advantages, challenges and limits of adopting visual models for the analysis of large corpora in television studies. Examples of data visualization will be notably shown here, in application to a sample database of anthology TV series extracted through the Wikidata Query Service. A visual model available on the platform RAWGraph will be proposed as a means to identify flows of production and distribution, by looking at the country of origin and at the industrial players involved in the formation of such a network. More than on actual modeling, we will therefore focus on model usage for academic research.

description: The subject of this thesis is the implementation of functional testing in a software library. More specifically, the purpose of this paper is the use of the model-based testing technique for the production of tests for the library Apache Commons Email. An abstract model of the system is created in Java and acts as an adaptor between the test program and the library we aimed to test. This technique helps to automatically generate many tests and allows their simultaneous application on the software under test. With different checks and targeted verification methods to the address fields, the method managed to reveal errors and omissions in this library.

description: One possible explanation for the substantial organismal differences between humans and chimpanzees is that there have been changes in gene regulation. Given what is known about transcription factor binding sites, this motivates the following probability question: given a 1000 nucleotide region in our genome, how long does it take for a specified six to nine letter word to appear in that region in some individual? Stone and Wray [Mol. Biol. Evol. 18 (2001) 1764--1770] computed 5,950 years as the answer for six letter words. Here, we will show that for words of length 6, the average waiting time is 100,000 years, while for words of length 8, the waiting time has mean 375,000 years when there is a 7 out of 8 letter match in the population consensus sequence (an event of probability roughly 5/16) and has mean 650 million years when there is not. Fortunately, in biological reality, the match to the target word does not have to be perfect for binding to occur. If we model this by saying that a 7 out of 8 letter match is good enough, the mean reduces to about 60,000 years.

description: This study is part of the BinaMIcS project which aims to understand the interaction between binarity and magnetism in different type of stars. Here, we present FK Aqr (GJ 867 A) – a double-line spectroscopic binary system consisting of two dM1-dwarfs with similar masses (0.55 Msun and 0.45 Msun for the primary and secondary, respectively). We were able to reconstruct the first maps of the surface magnetic field topologies of both components by employing the Zeeman Doppler imaging method. The data were obtained with ESPaDOnS spectropolarimeter at CFHT. Clear Stokes V signatures are detected from all observations of both components. The longitudinal magnetic field of the secondary is two times stronger than the primary’s one. The reconstructed maps show that both M-dwarfs have dipolar structures of their large-scale magnetic fields. This is in agreement with previous studies showing that M-dwarf stars, even in close binary pairs, can generate surface magnetic fields displaying a strong axisymmetric dipole component. We also note that the components of FK Aqr are among the most massive M-dwarfs known to generate this type of magnetic field. Orbital parameters of the system are refined employing the PHOEBE software based on the measurements of the radial velocities of both components from the mean Stokes I profiles.
