description: Binaries in double-lined spectroscopic systems provide a homogeneous set of stars. Differences of parameters, such as age or initial conditions, which otherwise would have strong impact on the stellar evolution, can be neglected. The observed differences are determined by the difference in stellar mass between the two components. The mass ratio can be determined with much higher accuracy than the actual stellar mass. In this work, we aim to study the eccentric binary system KIC9163796, whose two components are very close in mass and both are low-luminosity red-giant stars from four years of Kepler space photometry and high-resolution spectroscopy with Hermes. Mass and radius of the primary were determined through asteroseismology to be 1.39+/-0.06 Mo and 5.35+/-0.09 Ro, resp. From spectral disentangling the mass ratio was found to be 1.015+/-0.005 and that the secondary is ~600K hotter than the primary. Evolutionary models place both components, in the early and advanced stage of the first dredge-up event on the red-giant branch. From theoretical models of the primary, we derived the internal rotational gradient. From a grid of models, the measured difference in lithium abundance is compared with theoretical predictions. The surface rotation of the primary is determined from the Kepler light curve and resembles the orbital period within 10 days. The radial rotational gradient between the surface and core is found to be 6.9+2.0/-1.0. The agreement between the surface rotation with the seismic result indicates that the full convective envelope is rotating quasi-rigidly. The models of the lithium abundance are compatible with a rigid rotation in the radiative zone during the main sequence. Because of the many constraints offered by oscillating stars in binary systems, such objects are important test beds of stellar evolution.

description: Generalized Additive Models (GAMs) offer a balance between performance and interpretability in machine learning. The interpretability aspect of GAMs is expressed through shape plots, representing the model's decision-making process. However, the visual properties of these plots, e.g. number of kinks (number of local maxima and minima), can impact their complexity and the cognitive load imposed on the viewer, compromising interpretability. Our study, including 57 participants, investigates the relationship between the visual properties of GAM shape plots and cognitive load they induce. We quantify various visual properties of shape plots and evaluate their alignment with participants' perceived cognitive load, based on 144 plots. Our results indicate that the number of kinks metric is the most effective, explaining 86.4% of the variance in users' ratings. We develop a simple model based on number of kinks that provides a practical tool for predicting cognitive load, enabling the assessment of one aspect of GAM interpretability without direct user involvement.

description: The role of U-wire generated quadrupole like magnetic field configuration on loading of cold $^{87}Rb$ atoms in a magneto-optical trap (MOT) on atom-chip has been investigated. It is shown by simulations that the quadrupole field profile and the center of the quadrupole field vary depending upon the U-wire current and bias field values. The result of simulations show that the resemblance of generated field configuration to the ideal quadrupole field critically depends on the values of current in U-wire and bias magnetic field. The observed number of trapped atoms in the MOT and its position has also been found to depend on the quadrupole field configuration. The number of trapped atoms in the MOT reaches maximum when the field configuration approaches close to an ideal quadrupole field. This study will help in optimising the number in the MOT before transfer of these cold atoms in the atom-chip wire trap.

description: In this paper I consider a repeated buyer-seller relationship wherein a seller has private information on his fixed cost parameter. Once a buyer pays for the good - but before its delivery - he may fear opportunistic behavior by the seller; the latter may prefer not to produce, in which case he pays a penalty and the trade is terminated. Depending on the magnitude of the penalty and the valuation of the future I identify three contractual regimes corresponding to the strength of legal system. The optimal stationary contract consists of two distinct parts. For the most efficient types of seller, the contract entails bunching with a fixed payment and a fixed output. For higher costs output is significantly reduced below the optimal static mechanism.
A Generalized Tensor Formulation for Hyperspectral Image Super-Resolution Under General Spatial Blurring

description: Hyperspectral super-resolution is commonly accomplished by the fusing of a hyperspectral imaging of low spatial resolution with a multispectral image of high spatial resolution, and many tensor-based approaches to this task have been recently proposed. Yet, it is assumed in such tensor-based methods that the spatial-blurring operation that creates the observed hyperspectral image from the desired super-resolved image is separable into independent horizontal and vertical blurring. Recent work has argued that such separable spatial degradation is ill-equipped to model the operation of real sensors which may exhibit, for example, anisotropic blurring. To accommodate this fact, a generalized tensor formulation based on a Kronecker decomposition is proposed to handle any general spatial-degradation matrix, including those that are not separable as previously assumed. Analysis of the generalized formulation reveals conditions under which exact recovery of the desired super-resolved image is guaranteed, and a practical algorithm for such recovery, driven by a blockwise-group-sparsity regularization, is proposed. Extensive experimental results demonstrate that the proposed generalized tensor approach outperforms not only traditional matrix-based techniques but also state-of-the-art tensor-based methods; the gains with respect to the latter are especially significant in cases of anisotropic spatial blurring.

description: Class imbalance problem has been a challenging research problem in the fields of machine learning and data mining as most real life datasets are imbalanced. Several existing machine learning algorithms try to maximize the accuracy classification by correctly identifying majority class samples while ignoring the minority class. However, the concept of the minority class instances usually represents a higher interest than the majority class. Recently, several cost sensitive methods, ensemble models and sampling techniques have been used in literature in order to classify imbalance datasets. In this paper, we propose MEBoost, a new boosting algorithm for imbalanced datasets. MEBoost mixes two different weak learners with boosting to improve the performance on imbalanced datasets. MEBoost is an alternative to the existing techniques such as SMOTEBoost, RUSBoost, Adaboost, etc. The performance of MEBoost has been evaluated on 12 benchmark imbalanced datasets with state of the art ensemble methods like SMOTEBoost, RUSBoost, Easy Ensemble, EUSBoost, DataBoost. Experimental results show significant improvement over the other methods and it can be concluded that MEBoost is an effective and promising algorithm to deal with imbalance datasets.

description: A search for $T$ and $Y$ vector-like quarks produced in proton-proton collisions at a centre-of-mass energy of $13\,\text{TeV}$ and decaying into $Wb$ in the fully hadronic final state is presented. The search uses 139 fb$^{-1}$ of data collected by the ATLAS detector at the LHC from 2015 to 2018. The final state is characterised by a hadronically decaying $W$ boson with large Lorentz boost and a $b$-tagged jet, which are used to reconstruct the invariant mass of the vector-like quark candidate. The main background is QCD multijet production, which is estimated using a data-driven method. Upon finding no significant excess in data, mass limits at 95% confidence level are obtained as a function of the global coupling parameter, $κ$. The observed lower limits on the masses of $Y$ quarks with $κ= 0.5$ and $κ= 0.7$ are 2.0 TeV and 2.4 TeV, respectively. For $T$ quarks, the observed mass limits are 1.4 TeV for $κ= 0.5$ and 1.9 TeV for $κ= 0.7$.

description: In this paper, we implemented a set of title generation methods using training set of 21190 news stories and evaluated them on an independent test corpus of 1006 broadcast news documents, comparing the results over manual transcription to the results over automatically recognized speech. We use both F1 and the average number of correct title words in the correct order as metric. Overall, the results show that title generation for speech recognized news documents is possible at a level approaching the accuracy of titles generated for perfect text transcriptions.
An Exploration into Women’s Choice and Premarital Experiences of Arranged Marriages within a South Asian Community in Britain: An Interpretative Phenomenological Analysis

description: Arranged marriages are a common traditional practice within the South Asian community in Britain (Hemmings & Khalifa, 2013). There is ambiguity surrounding arranged marriage practices as the Home Office (2000) found practices vary from greatly coercive to completely consensual (Hemmings et al., 2013; Marcus, Begum, Alsabahi & Curtis, 2017). This is problematic as there is a lack of research which focuses on the psychological implications of arranged marriages, considering there is a varying degree of consent and pressure experienced. Therefore, this study explored the meaning of South Asian women’s lived premarital experiences of their arranged marriages, with particular attention to their experience of choice. Seven South Asian women in Britain were interviewed using semi-structured interviews. Transcripts were analysed using Interpretative Phenomenological Analysis, which captured the complexities and inter-subjective experiences within their cultural context (Smith, 1996). Four themes were identified: cultural and religious belief systems as influencers, the ripple of pressure, decision-making: negotiation of agency and choice, and self and identity. The themes highlight that women are confined within religious and cultural boundaries that guide their decisions. For South Asian women, permission is fundamental and being given a choice, is perceived as an indirect permission for women to exercise agency, to express their own needs and pursue behaviours in line with their identity. For these women, there were varying degrees of choice given to them at each stage of the process. Importantly, the experience of choice was meaningful for women, as this gave an opportunity for self expression and others caring about their wellbeing. Also, women experienced subtle pressure from their parents and the community, to ensure they uphold cultural duties. The premarital distress often led some women to subjugate their needs, and to accept and conform to alleviate psychological and emotional distress. Although some women exercised personal agency and pushed gender boundaries, many felt objectified due to the lack of involvement within the process, which challenged their sense of identity. This research informs clinical practice which is to provide South Asian women a safe therapeutic space to understand their own needs, tensions and feelings which may help women to feel connected to their experiences. Fundamentally, women voiced their need for more rights and involvement within the arrangement process, as their family’s needs were often prioritised. This research also proposes more community work for individuals to be aware of their basic human rights and to understand the subjective element of individual’s experiences in arranged marriages. Limitations and future areas for research are explored and discussed.
The Redistributive Potential of Section 7 of the Canadian Charter: Incorporating Socio-economic Context in Criminal Law and in the Adjudication of Rights

description: This article contrasts two series of arguments put forward by litigators for including social and economic context in the adjudication of rights protected by section 7 of the Canadian Charter of Rights and Freedoms, in order to assess the impact of 25 years of Charter litigation on the rights of the poor in the wake of the Re BC Motor Vehicle Act. The ﬁrst series of arguments focuses on the inclusion of poverty and social disadvantage in the deﬁnition of principles of fundamental justice relevant to the determination of criminal responsibility and insentencing. The second series of arguments articulates a broader conception of the right to life, liberty and security of the person. In light of the mitigated results obtained for the poor in both cases, this article discusses whether the problem lies in the constitutional nature of Charter litigation itself or in the ideological nature of social and economic arguments. Cet article met en opposition deux séries d’arguments présentés par des avocats en vue d’intégrer le contexte social et économique à l’adjudication de droits protégés par l’article 7 de la Charte canadienne des droits et libertés et ce, en vue d’évaluer l’incidence des 25 années de litiges relatifs à la Charte à propos des droits des pauvres dans la foulée de l’arrêt Renvoi sur la Motor Vehicle Act (C-B). La première série d’arguments met l’accent sur l’inclusion de la pauvreté et la condition sociale défavorable à la déﬁnition des principes de justice fondamentale pertinents aux ﬁ ns de déterminer la responsabilité pénale et la peine subséquente à imposer. Dans la seconde série d’arguments, on formule une conception élargie du droit à la vie, à la liberté et à la sécurité de la personne. À la lumière des résultats mitigés obtenus en faveur de la pauvreté dans les deux cas, cet article s’interroge à savoir si le problème réside dans la nature constitutionnelle des litiges portant sur la Charte ou dans la nature idéologique des arguments sociaux et économiques.

description: Spoken document retrieval is defined as information retrieval from transcribed spoken audio, and the basic approach is described. Research experiments demonstrate that information retrieval from transcribed speech can be done almost as effectively as from corresponding correct text. The retrieval performance is relatively immune to moderate amounts of speech recognition errors in the transcripts. Retrieval strategies using query expansion are valuable in mitigating effects of speech recognition errors. These can be supplemented by exploiting information that may be available from large parallel text corpora through automatic document and query augmentation. There is ongoing research in combining multilingual retrieval with spoken document retrieval and video retrieval, which requires spoken document retrieval together with video or image analysis. Some examples of successful applications of spoken document technology in practice are presented.

description: We show that nonsingular black holes realized in nonlinear electrodynamics are always prone to Laplacian instability around the center because of a negative squared sound speed in the angular direction. This is the case for both electric and magnetic BHs, where the instability of one of the vector-field perturbations leads to enhancing a dynamical gravitational perturbation in the even-parity sector. Thus, the background regular metric is no longer maintained in a steady state. Our results suggest that the construction of stable, nonsingular black holes with regular centers, if they exist, requires theories beyond nonlinear electrodynamics.

The process of creating an in-house interface for converting Blaise output into DDI metadata

Publisher: name: Zenodo
Year: 2019

description: ELIPSS (Longitudinal Internet Studies for Social Sciences) is a longitudinal probabilistic French panel. To release the 70 produced datasets, we had to deal with numerous issues, in a environment with limited resources and an important fragmentation of the tools: Blaise for the surveys, DDI-C for the documentation, SPSS for producing the datasets and SAS for the weights of the respondents. Also, heterogeneous survey programming and documentation practices had to be taken into account. Our primary goal was to favorise the reuse of data and metadata. To handle the challenges of this project, it was necessary to imagine and implement new processes and tools that are adapted to the context and have the smallest impact on the existing environment to increase the quality and the efficiency of the data management. The solution we found was to create an interface, a liaison between all the tools for fluidizing the production and dissemination cycle of the datasets. The solution we conceived is based on the output and the input files of the software linked between them by a tool developed with R. This presentation underlines the building process of this solution. We also give feedback on how it performed during 5 years in our environment.

description: Gold nanorods grafted with short chain polymers are assembled into controlled open structures using polymer-induced depletion interactions and structurally characterized using small angle x-ray scattering. When the nanorod diameter is smaller than the radius of gyration of the depletant polymer, the depletion interaction depends solely on the correlation length of the polymer solution and not directly on the polymer molecular weight. As the polymer concentration increases, the stronger depletion interactions increasingly compress the grafted chains and push the gold nanorods closer together. By contrast, other structural characteristics such as the number of nearest neighbors and fractal dimension exhibit a non-monotonic dependence on polymer concentration. These parameters are maximal at intermediate concentrations, which are attributed to a crossover from reaction-limited to diffusion-limited aggregation. The control over structural properties of anisotropic nanoscale building blocks demonstrated here will be beneficial to designing and producing materials \emph{in situ} with specific direction-dependent nanoscale properties and provides a crucial route for advances in additive manufacturing.

description: Machine Translation of minority languages presents unique challenges, including the paucity of bilingual training data and the unavailability of linguistically-trained speakers. This paper focuses on a machine learning approach to transfer-based MT, where data in the form of translations and lexical alignments are elicited from bilingual speakers, and a seeded version-space learning algorithm formulates and refines transfer rules. A rule-generalization lattice is defined based on LFG-style f-structures, permitting generalization operators in the search for the most general rules consistent with the elicited data. The paper presents these methods and illustrates examples.

L’EXPÉRIENCE DES PARENTS IMMIGRANTS AYANT UN ENFANT ATTEINT DU TROUBLE DU COMPORTEMENT ALIMENTAIRE

description: L’objectif de ce mémoire est de présenter l’expérience des parents immigrants ayant un enfant atteint du trouble du comportement alimentaire. Il expose l’influence du trouble du comportement alimentaire des enfants sur le quotidien des parents immigrants et la fratrie. Pour mener à bien cette recherche, nous avons posé la question de recherche suivante: Quelle est l’expérience des parents immigrants ayant un enfant atteint de troubles du comportement alimentaire? Pour répondre à cette question, l’approche transculturelle a été choisie comme cadre théorique, ce qui a permis d’orienter nos recherches vers la culture, qui est un élément important pour les personnes immigrantes. De ce fait, nous avons réalisé des entrevues semi-dirigées auprès de trois parents d’origine africaine vivant tous dans la région d'Ottawa et ayant chacun une fille atteinte d’anorexie mentale. Au cours de cette recherche, nous avons pu atteindre nos trois objectifs de recherche qui étaient : documenter l’expérience des parents immigrants qui ont un enfant atteint du trouble du comportement alimentaire; décrire les moyens mis en œuvre par les parents immigrants pour composer avec la maladie de leur enfant à toutes les étapes du processus de soin allant du diagnostic de la maladie à la guérison, s’il y a lieu ; explorer le style d’accompagnement et de soutien offert aux parents immigrants par les services de santé ainsi que la relation entretenue avec ces derniers. Les résultats obtenus nous ont permis de mettre en lumière la perception du trouble du comportement alimentaire au sein de la communauté immigrante, l’influence du trouble alimentaire sur la dynamique familiale, l’aide reçue des proches pendant le processus de guérison des enfants et l’avis des parents immigrants sur la prise en charge de leurs enfants par l’équipe de professionnels de la santé. Par ailleurs, nous avons constaté que les parents immigrants rencontrent des difficultés à reconnaître les signes caractéristiques de troubles du comportement alimentaire chez leurs enfants. Cette méconnaissance peut retarder la prise en charge des enfants malades par les professionnels de la santé et aggraver leur état de santé. Aussi, les parents immigrants reçoivent peu d’aide des membres de leur réseau social et font plutôt l’objet de nombreuses critiques dues à l’incompréhension du trouble alimentaire souvent présente dans la communauté immigrante.  Ainsi, nous pensons qu’il est nécessaire de faire de la sensibilisation sur la santé mentale en général et les troubles alimentaires en particulier dans les communautés immigrantes. De plus, nous invitons les professionnels de la santé à acquérir des compétences en intervention interculturelles afin de mieux répondre aux besoins des familles immigrantes.   Mots-clés : Trouble du comportement alimentaire, parents immigrants, anorexie, approche transculturelle, santé mentale, culture

description: M-type stars are the most common stars in the universe. They are ideal hosts for the search of exoplanets in the habitable zone (HZ), as their small size and low temperature make the HZ much closer in than their solar twins. Harboring very deep convective layers, they also usually exhibit very intense magnetic fields. Understanding their environment, in particular their coronal and wind properties, is thus very important, as they might be very different from what is observed in the solar system. The mass loss rate of M-type stars is poorly known observationally, and recent attempts to estimate it for some of them (TRAPPIST-1, Proxima Cen) can vary by an order of magnitude. In this work, we revisit the stellar wind properties of M-dwarfs in the light of the latest estimates of $\dot{M}$ through Lyman-$α$ absorption at the astropause and slingshot prominences. We outline a modeling strategy to estimate the mass loss rate, radiative loss and wind speed, with uncertainties, based on an Alfvén wave driven stellar wind model. We find that it is very likely that several TRAPPIST-1 planets lie within the Alfvén surface, which imply that these planets experience star-planet magnetic interactions (SPMI). We also find that SPMI between Proxima Cen b and its host star could be the reason of recently observed radio emissions.

description: We describe the general structure of the well known S255IR high mass star forming region, as revealed by our recent ALMA observations. The data indicate a physical relation of the major clumps SMA1 and SMA2. The driving source of the extended high velocity well collimated bipolar outflow is not the most pronounced disk-like SMA1 clump harboring a 20 M$_\odot$ young star (S255 NIRS3), as it was assumed earlier. Apparently it is the less evolved SMA2 clump, which drives the outflow and contains a compact rotating structure (probably a disk). At the same time the SMA1 clump drives another outflow, with a larger opening angle. The molecular line data do not show an outflow from the SMA3 clump (NIRS1), which was suggested by IR studies of this region.

description: Given an image (or video clip, or audio song), how do we automatically assign keywords to it? The general problem is to find correlations across the media in a collection of multimedia objects like video clips, with colors, and/or motion, and/or audio, and/or text scripts. We propose a novel, graph-based approach, "MMG", to discover such cross-modal correlations.Our "MMG" method requires no tuning, no clustering, no user-determined constants; it can be applied to any multimedia collection, as long as we have a similarity function for each medium; and it scales linearly with the database size. We report auto-captioning experiments on the "standard" Corel image database of 680 MB, where it outperforms domain specific, fine-tuned methods by up to 10 percentage points in captioning accuracy (50% relative improvement).

description: We perform a matching of the two loop-chiral perturbation theory representation of the scalar Kpi form factor to a dispersive one. Knowing the value of F_K/F_pi and f_+(0) in the Standard Model (SM) allows to determine two O(p^6) LECs, the slope of the scalar form factor and the deviation of the Callan-Treiman theorem. Going beyond the SM and assuming the knowledge of the slope of the scalar form factor from experiment, the matching allows us to determine the ratio of F_K/F_pi, f_+(0), a certain combination of non-standard couplings, the deviation of the Callan-Treiman theorem and the two O(p^6) LECs.

Internal Variations in Empirical Oxygen Abundances for Giant HII Regions in the Galaxy NGC 2403

description: This paper presents a spectroscopic investigation of 11 HII regions in the nearby galaxy NGC 2403. The HII regions are observed with a long-slit spectrograph mounted on the 2.16 m telescope at XingLong station of National Astronomical Observatories of China. For each of the HII regions, spectra are extracted at different nebular radii along the slit-coverage. Oxygen abundances are empirically estimated from the strong-line indices R23, N2O2, O3N2, and N2 for each spectrophotometric unit, with both observation- and model-based calibrations adopted into the derivation. Radial profiles of these diversely estimated abundances are drawn for each nebula. In the results, the oxygen abundances separately estimated with the prescriptions on the basis of observations and models, albeit from the same spectral index, systematically deviate from each other; at the same time, the spectral indices R23 and N2O2 are distributed with flat profiles, whereas N2 and O3N2 exhibit apparent gradients with the nebular radius. Because our study naturally samples various ionization levels which inherently decline at larger radii within individual HII regions, the radial distributions indicate not only the robustness of R23 and N2O2 against ionization variations but also the sensitivity of N2 and O3N2 to the ionization parameter. The results in this paper provide observational corroboration of the theoretical prediction about the deviation in the empirical abundance diagnostics. Our future work is planned to investigate metal-poor HII regions with measurable T_e, in an attempt to recalibrate the strong-line indices and consequently disclose the cause of the discrepancies between the empirical oxygen abundances.

description: Aggressive prefetching is an effective technique for reducing the execution times of disk-bound applications; that is, applications that manipulate data too large or too infrequently used to be found in file or disk caches. While automatic prefetching approaches based on static analysis or historical access patterns are effective for some workloads, they are not as effective as manually-driven (programmer-inserted) prefetching for applications with irregular or input-dependent access patterns. In this paper, we propose to exploit whatever processor cycles are left idle while an application is stalled on I/O by using these cycles to dynamically analyze the application and predict its future I/O accesses. Our approach is to speculatively pre-execute the application's code in order to discover and issue hints for its future read accesses. Coupled with an aggressive hint-driven prefetching system, this automatic approach could be applied to arbitrary applications, and should be particularly effective for those with irregular and, up to a point, input-dependent access patterns. We have designed and implemented a binary modification tool, called "SpecHint", that transforms Digital UNIX application binaries to perform speculative execution and issue hints. TIP [Patterson95], an informed prefetching and caching manager, takes advantage of these application-generated hints to better use the file cache and I/O resources. We evaluate our design and implementation with three real-world, disk-bound applications from the TIP benchmark suite. While our techniques are currently unsophisticated, they perform surprisingly well. Without any manual modifications, we achieve 29%, 69% and 70% reductions in execution time when the data files are striped over four disks, improving performance by the same amount as manually-hinted prefetching for two of our three applications. We examine the performance of our design in a variety of configurations, explaining the circumstances under which it falls short of that achieved when applications were manually modified to issue hints. Through simulation, we also estimate how the performance of our design will be affected by the widening gap between processor and disk speeds.

description: Cu$_2$IrO$_3$ has attracted recent interest due to its proximity to the Kitaev quantum spin liquid state and the complex structural response observed at high pressures. We use x-ray spectroscopy and scattering as well as electrical transport techniques to unveil the electronic structure of Cu$_2$IrO$_3$ at ambient and high pressures. Despite featuring a $\mathrm{Ir^{4+}}$ $J_{\rm{eff}}=1/2$ state at ambient pressure, Ir $L_{3}$ edge resonant inelastic x-ray scattering reveals broadened electronic excitations that point to the importance of Ir $5d$-Cu $3d$ interaction. High pressure first drives an Ir-Ir dimer state with collapsed $\langle \mathbf{L} \cdot \mathbf{S} \rangle$ and $\langle L_z \rangle/\langle S_z \rangle$, signaling the formation of $5d$ molecular orbitals. A novel $\mathrm{Cu \to Ir}$ charge transfer is observed at the onset of phase 5 above 30 GPa at low temperatures, leading to an approximate $\mathrm{Ir^{3+}}$ and $\mathrm{Cu^{1.5+}}$ valence, with persistent insulating electrical transport seemingly driven by charge segregation of Cu 1+/2+ ions into distinct sites. Concomitant x-ray spectroscopy and scattering measurements through different thermodynamic paths demonstrate a strong electron-lattice coupling, with $J_{\rm{eff}}=1/2$ and $\mathrm{Ir^{3+}}$/$\mathrm{Cu^{1.5+}}$ electronic states occurring only in phases 1 and 5, respectively. Remarkably, the charge-transferred state can only be reached if Cu$_2$IrO$_3$ is pressurized at low temperature, suggesting that phonons play an important role in the stability of this phase. These results point to the choice of thermodynamic path across interplanar collapse transition as a key route to access novel states in intercalated iridates.
