description: SN 2017jgh is a type IIb supernova discovered by Pan-STARRS during the C16/C17 campaigns of the Kepler/K2 mission. Here we present the Kepler/K2 and ground based observations of SN 2017jgh, which captured the shock cooling of the progenitor shock breakout with an unprecedented cadence. This event presents a unique opportunity to investigate the progenitors of stripped envelope supernovae. By fitting analytical models to the SN 2017jgh lightcurve, we find that the progenitor of SN 2017jgh was likely a yellow supergiant with an envelope radius of $\sim50-290~R_{\odot}$, and an envelope mass of $\sim0-1.7~M_{\odot}$. SN 2017jgh likely had a shock velocity of $\sim7500-10300$ km s$^{-1}$. Additionally, we use the lightcurve of SN 2017jgh to investigate how early observations of the rise contribute to constraints on progenitor models. Fitting just the ground based observations, we find an envelope radius of $\sim50-330~R_{\odot}$, an envelope mass of $\sim0.3-1.7~M_{\odot}$ and a shock velocity of $\sim9,000-15,000$ km s$^{-1}$. Without the rise, the explosion time can not be well constrained which leads to a systematic offset in the velocity parameter and larger uncertainties in the mass and radius. Therefore, it is likely that progenitor property estimates through these models may have larger systematic uncertainties than previously calculated.

description: This paper is concerned with the numerical approximation of the isothermal Euler equations for charged particles subject to the Lorentz force. When the magnetic field is large, the so-called drift-fluid approximation is obtained. In this limit, the parallel motion relative to the magnetic field direction splits from perpendicular motion and is given implicitly by the constraint of zero total force along the magnetic field lines. In this paper, we provide a well-posed elliptic equation for the parallel velocity which in turn allows us to construct an Asymptotic-Preserving (AP) scheme for the Euler-Lorentz system. This scheme gives rise to both a consistent approximation of the Euler-Lorentz model when epsilon is finite and a consistent approximation of the drift limit when epsilon tends to 0. Above all, it does not require any constraint on the space and time steps related to the small value of epsilon. Numerical results are presented, which confirm the AP character of the scheme and its Asymptotic Stability.

description: Dark matter's existence is known thanks to its gravitational interaction with Standard Model particles, but it remains unknown whether this is the only force present between them. While many searches for such new interactions with dark matter focus on short-range, contact-like interactions, it is also possible that there exist weak, long-ranged forces between dark matter and the Standard Model. In this work, we present two types of constraints on such new interactions. First, we consider constraints arising from the fact that such a force would also induce long range interactions between Standard Model particles themselves, as well as between dark matter particles themselves. Combining the constraints on these individual forces generally sets the strongest constraints available on new Standard Model-dark matter interactions. Second, we consider the possibility of constraining new long-ranged interactions between dark matter and the Standard Model using the effects of dynamical friction in ultrafaint dwarf galaxies, especially Segue I. Such new interactions would accelerate the transfer of kinetic energy from stars to their surrounding dark matter, slowly reducing their orbits; the present-day stellar half-light radius of Segue I therefore allows us to exclude new forces which would have reduced stars' orbital radii below this scale by now.

description: We study the phases and phase transitions of a disordered one-dimensional quantum $q$-state clock Hamiltonian using large-scale Monte Carlo simulations. Making contact with earlier results, we confirm that the clean, translational invariant version of the model, for $q=6$, hosts an intermediate emergent quasi-long-range ordered (QLRO) phase between the symmetry-broken true long-range ordered (TLRO) phase and the disordered (paramagnetic) phase. With increasing disorder strength, the quasi-long-range ordered phase shrinks and finally vanishes at a multi-critical point, beyond which there is a direct transition from the TLRO phase to the paramagnetic phase. After establishing the phase diagram, we characterize the critical behaviors of the various quantum phase transitions in the model. We find that weak disorder is an irrelevant perturbation of the Berezinskii-Kosterlitz-Thouless transitions that separate the QLRO phase from the TLRO and paramagnetic phases. For stronger disorder, some of the critical exponents become disorder-dependent already before the system reaches the multicritical point. We also show that beyond the multicritical point, the direct transition from the TLRO phase to the paramagnetic phase is governed by an infinite-randomness critical point in line with strong-disorder renormalization group predictions. While our numerical results are for $q=6$, we expect the qualitative features of the behavior to hold for all $q>4$.

description: Knowledge Distillation is a commonly used Deep Neural Network (DNN) compression method, which often maintains overall generalization performance. However, we show that even for balanced image classification datasets, such as CIFAR-100, Tiny ImageNet and ImageNet, as many as 41% of the classes are statistically significantly affected by distillation when comparing class-wise accuracy (i.e. class bias) between a teacher/distilled student or distilled student/non-distilled student model. Changes in class bias are not necessarily an undesirable outcome when considered outside of the context of a model's usage. Using two common fairness metrics, Demographic Parity Difference (DPD) and Equalized Odds Difference (EOD) on models trained with the CelebA, Trifeature, and HateXplain datasets, our results suggest that increasing the distillation temperature improves the distilled student model's fairness, and the distilled student fairness can even surpass the fairness of the teacher model at high temperatures. Additionally, we examine individual fairness, ensuring similar instances receive similar predictions. Our results confirm that higher temperatures also improve the distilled student model's individual fairness. This study highlights the uneven effects of distillation on certain classes and its potentially significant role in fairness, emphasizing that caution is warranted when using distilled models for sensitive application domains.

There exists many interesting cases where we obtain proper matter collineations.

description: In this work, we investigate the MOdified Gravity (MOG) theory for dynamics of the universe and compare the results with the $Λ$CDM cosmology. We study the background cosmological properties of the MOG model and structure formation at the linear perturbation level. We compare the two models with the currently available cosmological data by using statistical Bayesian analyses. After obtaining updated constraints on the free parameters, we use some methods of model selection to assist in choosing the more consistent model such as the reduced chi-squared ($χ^2_{\rm red}$) and a number of the basic information criteria such as the Akaike Information Criterion (AIC), the Bayes factor or Bayesian Information Criterion (BIC), and Deviance Information Criterion (DIC). MOG model appears to be consistent with the $Λ$CDM model by the results of $χ^2_{\rm red}$ and DIC for an overall statistical analysis using the background data and the linear growth of structure formation.

description: Binaries with a Wolf-Rayet star and a compact object (WR-COs), either a black hole (BH) or a neutron star (NS), have been proposed as possible progenitors for the binary compact object mergers (BCOs) observed with the gravitational wave (GW) detectors. In this work, we use the open-source population synthesis code SEVN to investigate the role of WR-COs as BCO progenitors. We consider an initial population of $5 \times 10^6$ binaries and we evolve it across 96 combinations of metallicities, common envelope efficiencies, core-collapse supernova models and natal kick distributions. We find that WR-COs are the progenitors of most BCOs, especially at high and intermediate metallicity. At $Z=0.02,\,{}0.014,$ and $0.0014$, more than $\gtrsim 99 \%$ of all the BCOs in our simulations evolved as WR-COs. At $Z = 0.00014$, inefficient binary-stripping lowers the fraction of BCOs with WR-CO progenitors to $\approx 83-95 \%$. Despite their key role in BCO production, only $\approx 5-30 \%$ of WR-COs end their life as BCOs. We find that Cyg X-3, the only WR-CO candidate observed in the Milky Way, is a promising BCO progenitor, especially if it hosts a BH. In our simulations, about $\approx 70-100 \%$ of the Cyg X-3 - like systems in the WR-BH configuration (BH mass $ \leq 10 \rm ~ M_\odot$) are BCO progenitors, in agreement with the literature. Future observations of WR-COs similar to Cyg X-3 may be the Rosetta stone to interpret the formation of BCOs.

title: Augmenting the Site Analysis Phase of the Design Process Using Virtual Reality and Drones
Creators: name: Blauer, Brandon
Publisher: name: Utah State University
Year: 2021

description: Virtual reality (VR) is a tool that has been utilized by designers for decades now. In most cases, VR has been utilized in the latter part of the design process. More specifically, VR has been used most commonly towards the design review phase of the design process where people are often looking for a final design suggestion. With regards to the design review phase, there have been many reports discussing the effectiveness of VR. However, there has been little to no research regarding the use of VR in the site analysis phase of the design process.
This thesis develops a methodology for generating a three-dimensional (3-D) terrain model using drones and photogrammetry software, then importing the 3-D terrain model to an immersive virtual reality program, along with GIS data and other online resources, to conduct a large-scale site analysis using VR.
This thesis uses the site Powder Mountain, Utah to explore ways of integrating VR into the site analysis phase design process. Powder Mountain includes 10,000 acres of rough terrain and steep slopes. The analysis focus was prioritized by existing program elements generated by Summit Powder Mountain.
The results of this study suggest that this methodology can enhance the site analysis process by increasing the connectivity of designers to existing site conditions, allowing designers to frequently reference site conditions as they proceed to later phases of the design process. VR also provides designers with a means to express their site analysis in a manner that is spatially connected to the site, rather than via abstracted 2-dimensional models and representations.

description: Beyond testing the current cosmological paradigm, cluster number counts can also be utilized to investigate the discrepancies currently affecting current cosmological measurements. In particular, cosmological studies based on cosmic shear and other large-scale structure probes routinely find a value of the amplitude of the fluctuations in the universe S8 smaller than the one inferred from the primary cosmic microwave background. In this work, we investigate this tension by measuring structure evolution across cosmic time as probed by the number counts of the massive halos with the first SRG/eROSITA All-Sky Survey cluster catalog in the Western Galactic Hemisphere complemented with the overlapping Dark Energy Survey Year-3, KiloDegree Survey, and Hyper Suprime-Cam data for weak lensing mass calibration, by implementing two different parameterizations and a model-agnostic method. In the first model, we measure the cosmic linear growth index as γ = 1.19 \pm 0.21, in tension with the standard value of γ = 0.55, but in good statistical agreement with other large-scale structures probes. The second model is a phenomenological scenario in which we rescale the linear matter power spectrum at low redshift to investigate a potential reduction of structure formation, providing similar results. Finally, in a third strategy, we consider a standard ΛCDM cosmology, but we separate the cluster catalog into five redshift bins, measuring the cosmological parameters in each and inferring the evolution of the structure formation, finding hints of a reduction. Interestingly, the S8 value inferred from eRASS1 cluster number counts, when we add a degree of freedom to the matter power spectrum, recovers the value inferred by cosmic shear studies.

description: This paper is devoted to the evaluation of the energy-momentum density components for the Friedmann models. For this purpose, we have used M$ø$ller's pseudotensor prescription in General Relativity and a certain energy-momentum density developed from his teleparallel formulation. It is shown that the energy density of the closed Friedmann universe vanishes on the spherical shell at the radius $ρ=2\sqrt{3}$. This coincides with the earlier results available in the literature. We also discuss the energy of the flat and open models. A comparison shows a partial consistency between the M$ø$ller's pseudotensor for General Relativity and teleparallel theory. Further, it is shown that the results are independent of the free dimensionless coupling constant of the teleparallel gravity.

description: We describe the conjugation of the reddening sequence according to the formula of $c$-vectors with respect to changing the initial seed. As applications, we extend the Rotation Lemma, the Target before Source Theorem, and the mutation invariant property of the existence of reddening sequences to totally sign-skew-symmetric cluster algebras. Furthermore, this also leads to the construction of conjugation difference which characterizes the number of red mutations a maximal green sequence should admit in any matrix pattern with the initial seed changed via mutations.
title: The Sea Calls: A Selkie's Liminal Existence
Creators: name: Avery, Frances
Publisher: name: Utah State University
Year: 2021

description: Traditionally, the selkies (or seal people) of Scottish-Irish lore exist between spaces: the land and the sea, human and animal, childbearing and childless. Their existence at sea is voluntary but their existence on land is forced. Once the selkie has left behind its sealskin and both the literal and metaphorical sealskin has been stolen, the selkie becomes subject to human will. The lenses of body, reclamation, violation, and abuse prove that the reason why selkies have faded from popularity is because the lessons are too mature for a young audience. A feminist and queer reading and interpretation of this traditional tale not only demonstrates the sexual and domestic subjugation that marginalized characters in folklore endure, but also explores the non-belonging that occurs when existing in the liminal.
Photometric Oscillations of Low Luminosity Red Giant Stars

Publisher: name: arXiv

Subjects: subject: Astrophysics (astro-ph)

description: I present details of the variations of several hundred red giant stars on time scales of a few hours to a few days from Hubble Space Telescope (HST) observations of a low-extinction galactic bulge sample from an intensive seven day campaign. Variations in the red giants are shown to be a strong function of position within the color-magnitude diagram (CMD) in accord with general expectations from theory. Amplitudes are greater for stars with larger radii, whether this results from higher luminosity at the same effective temperature or lower temperature at a fixed apparent magnitude. Likewise, characteristic time scales for the variations increase to the upper right in a CMD as does the ratio of amplitudes measured at 606 nm compared to 814 nm. Characteristic variation time scales are well matched by low-order radial pulsation modes. The effective sample discussed here extends from about two magnitudes above the bulge turnoff at which red giant radii are ~7 R/R_{\odot} at 5,000 K with typical amplitudes of ~0.5 mmag to ~40 R/R_{\odot} at 4,000 K with amplitudes of ~3.5 mmag. Variability characteristics are quite similar at any given position in the CMD, and at levels in the CMD where oscillations are easily detected nearly all red giants show such. If these variations represent oscillations with sufficient lifetimes to derive accurate mode frequencies more extensive observations, e.g. as should soon be provided by the Kepler Mission}, would provide a rich asteroseismic return.

description: Rydberg dressing is a powerful tool for entanglement generation in long-lived atomic states. While already employed effectively in several demonstrations, a key challenge for this technique is the collective loss triggered by blackbody-radiation-driven transitions to contaminant Rydberg states of opposite parity. We demonstrate the rapid removal of such contaminants using autoionization (AI) transitions found in alkaline-earth-like atoms. The AI is shown to be compatible with coherent operation of an array of optical clock qubits. By incorporating AI pulses into a stroboscopic Rydberg dressing (SRD) sequence, we enhance lifetimes by an order of magnitude for system sizes of up to 144 atoms, while maintaining an order of magnitude larger duty cycle than previously achieved. To highlight the utility of our approach, we use the AI-enhanced SRD protocol to improve the degree of spin-squeezing achieved during early-time dressing dynamics. These results bring Rydberg dressing lifetimes closer to fundamental limits, opening the door to previously infeasible dressing proposals.

description: The Gaia mission is a magnitude-limited whole-sky survey that collects an impressive quantity of astrometric, spectro-photometric and spectroscopic data. Among all the on-board instruments, the Radial Velocity Spectrometer (RVS) produces millions of spectra up to a magnitude of G$_{RVS} \sim 16$. For the brightest RVS targets, stellar atmospheric parameters and individual chemical abundances are automatically estimated by the Generalized Stellar Parametriser - spectroscopy group (GSP-Spec). These data will be published with the third Gaia Data Release. Some major ingredients of the determination of these stellar parameters include the atomic and molecular line lists that are adopted to compute reference synthetic spectra, on which the parametrisation methods rely. We aim to build such a specific line list optimised for the analysis of RVS late-type star spectra. Starting from the Gaia-ESO line lists, we first compared the observed and synthetic spectra of six well-known reference late-type stars in the wavelength range covered by the RVS instrument. We then improved the quality of the atomic data for the transitions presenting the largest mismatches. The new line list is found to produce very high-quality synthetic spectra for the tested reference stars and has thus been adopted within GSP-Spec.

b anti-b Higgs production at the LHC: Yukawa corrections and the leading Landau singularity

Year: 2008
Subjects: subject: High Energy Physics - Phenomenology (hep-ph)

description: At tree-level Higgs production in association with a b-quark pair proceeds through the small Yukawa bottom coupling in the Standard Model. Even in the limit where this coupling vanishes, electroweak one-loop effects, through the top-Higgs Yukawa coupling in particular, can still trigger this reaction. This contribution is small for Higgs masses around 120GeV but it quickly picks up for higher Higgs masses especially because the one-loop amplitude develops a leading Landau singularity and new thresholds open up. These effects can be viewed as the production of a pair of top quarks which rescatter to give rise to Higgs production through WW fusion. We study the leading Landau singularity in detail. Since this singularity is not integrable when the one-loop amplitude is squared, we regulate the cross section by taking into account the width of the internal top and W particles. This requires that we extend the usual box one-loop function to the case of imaginary masses. We show how this can be implemented analytically in our case. We study in some detail the cross section at the LHC as a function of the Higgs mass and show how some distributions can be drastically affected compared to the tree-level result.

description: We have studied the wave properties of the cold and isothermal plasma in the vicinity of the Schwarzschild black hole event horizon. The Fourier analyzed perturbed 3+1 GRMHD equations are taken on the basis of which the complex dispersion relations are obtained for non-rotating, rotating non-magnetized and rotating magnetized backgrounds. The propagation and attenuation vectors along with the refractive index are obtained (shown in graphs) to study the dispersive properties of the medium near the event horizon. The results show that no information can be obtained from the Schwarzschild magnetosphere. Further, the pressure ceases the existence of normal dispersion of waves.

title: Corporate Venture Capital and Its Effects on Company Valuation - An Analysis of the Additions of CVC Arms
Creators: name: Lyman, Joshua
Publisher: name: Utah State University
Year: 2021

description: This paper examines the stock price reaction to the addition of corporate venture capital arms to publicly traded companies. Referencing venture capital resources, corporate press release announcements of the addition of CVC arms were hand collected. I calculate the cumulative abnormal returns (CARs) surrounding press release announcement dates and find immediate stock market reactions, positively increasing stock prices compared to the overall market. I further perform placebo event studies at random dates and with direct competitors using the same announcement dates and find no significant results. These findings suggest that corporate venture capital increases company valuation and that financial markets positively value corporate venture capital arms.

description: Recent advances in diffusion models have opened new avenues for research into embodied AI agents and robotics. Despite significant achievements in complex robotic locomotion and skills, mobile manipulation-a capability that requires the coordination of navigation and manipulation-remains a challenge for generative AI techniques. This is primarily due to the high-dimensional action space, extended motion trajectories, and interactions with the surrounding environment. In this paper, we introduce M2Diffuser, a diffusion-based, scene-conditioned generative model that directly generates coordinated and efficient whole-body motion trajectories for mobile manipulation based on robot-centric 3D scans. M2Diffuser first learns trajectory-level distributions from mobile manipulation trajectories provided by an expert planner. Crucially, it incorporates an optimization module that can flexibly accommodate physical constraints and task objectives, modeled as cost and energy functions, during the inference process. This enables the reduction of physical violations and execution errors at each denoising step in a fully differentiable manner. Through benchmarking on three types of mobile manipulation tasks across over 20 scenes, we demonstrate that M2Diffuser outperforms state-of-the-art neural planners and successfully transfers the generated trajectories to a real-world robot. Our evaluations underscore the potential of generative AI to enhance the generalization of traditional planning and learning-based robotic methods, while also highlighting the critical role of enforcing physical constraints for safe and robust execution.
title: Performance and Contributions of the Green Industry to Utah's Economy

description: Landscaping and nursery enterprises, commonly known as green industry enterprises, can be found everywhere in Utah, and are necessary to create both aesthetic appeal and human well-being in the built environment. In order to understand the impact that events such as economic shocks or policy changes may have on the green industry, the baseline performance and contribution of the industry must be specified for comparison following these shocks. This study provides a summary and evaluation of the current performance of the green industry in Utah, and estimates the industry’s contributions to Utah’s economy in terms of transactions between industries, employee compensation, and government tax revenue using economic multipliers from the IMPLAN (IMpact analysis for PLANning) model for Utah. While the green industry contributed less than 1% of overall employment and taxable sales in Utah in 2018, the follow-on economic impacts contributed by green industry activity are important to consider. More than 12 thousand green industry jobs distributed throughout the state stimulated an additional 6,679 jobs in the wider economy through business-to-business purchasing and employee spending.

description: We consider the problem of detecting, isolating and classifying elephant calls in continuously recorded audio. Such automatic call characterisation can assist conservation efforts and inform environmental management strategies. In contrast to previous work in which call detection was performed at a segment level, we perform call detection at a frame level which implicitly also allows call endpointing, the isolation of a call in a longer recording. For experimentation, we employ two annotated datasets, one containing Asian and the other African elephant vocalisations. We evaluate several shallow and deep classifier models, and show that the current best performance can be improved by using an audio spectrogram transformer (AST), a neural architecture which has not been used for this purpose before, and which we have configured in a novel sequence-to-sequence manner. We also show that using transfer learning by pre-training leads to further improvements both in terms of computational complexity and performance. Finally, we consider sub-call classification using an accepted taxonomy of call types, a task which has not previously been considered. We show that also in this case the transformer architectures provide the best performance. Our best classifiers achieve an average precision (AP) of 0.962 for framewise binary call classification, and an area under the receiver operating characteristic (AUC) of 0.957 and 0.979 for call classification with 5 classes and sub-call classification with 7 classes respectively. All of these represent either new benchmarks (sub-call classifications) or improvements on previously best systems. We conclude that a fully-automated elephant call detection and subcall classification system is within reach. Such a system would provide valuable information on the behaviour and state of elephant herds for the purposes of conservation and management.

description: It has been shown that the diversity of the aromatic emission features can be rationalized into different classes of objects, in which differences between circumstellar and interstellar matter are emphasised. We probe the links between the mid-IR emitters observed in planetary nebulae (PNe) and their counterparts in the interstellar medium in order to probe a scenario in which the latter have been formed in the circumstellar environment of evolved stars. The mid-IR (6-14 um) emission spectra of PNe and compact HII regions were analysed on the basis of previous work on photodissociation regions (PDRs). Galactic, Large Magellanic Cloud (LMC), and Small Magellanic Cloud (SMC) objects were considered in our sample.We show that the mid-IR emission of PNe can be decomposed as the sum of six components. Some components made of polycyclic aromatic hydrocarbon (PAH) and very small grain (VSG) populations are similar to those observed in PDRs. Others are fitted in an evolutionary scenario involving the destruction of the aliphatic component observed in the post-AGB stage, as well as strong processing of PAHs in the extreme conditions of PNe that leads to a population of very large ionized PAHs. This species called PAH^x are proposed as the carriers of a characteristic band at 7.90 um. This band can be used as part of diagnostics that identify PNe in nearby galaxies and is also observed in galactic compact HII regions. These results support the formation of the aromatic very small dust particles in the envelopes of evolved stars, in the Milky Way, as well as in the LMC and SMC, and their subsequent survival in the interstellar medium.

CO₂ excretion and acid-base regulation in the rainbow trout, Salmo gairdneri
Creators: name: Haswell, Monty Stephen
Publisher: name: University of British Columbia
Year: 2010

description: The role of carbonic anhydrase in carbon dioxide excretion and acid-base regulation in the rainbow trout, Salmo gairdneri has been investigated. While a significant amount of carbonic anhydrase was found in the blood of the trout, calculations based on red cell hemolysates suggest that the probable circulating levels of carbonic anhydrase activity in blood may not be sufficient to account for the observed carbon dioxide excretion. An analysis of carbonic anhydrase activity in whole blood from the trout revealed that intact fish erythrocytes, unlike mammalian erythrocytes totally fail to facilitate the dehydration of extracellular bicarbonate. The possible mechanism of this phenomenon has been examined; however the salient point was that fish red blood cells do not appear capable and therefore by implication apparently not necessary for the excretion of carbon dioxide at the gills of trout. The observed excretion of carbon dioxide in the trout was found to be accounted for by the gills and their compliment of carbonic anhydrase. This finding was based on the following observations. (1) Depletion of circulating blood carbonic anhydrase levels during severe anemia was without effect on carbon dioxide excretion rates or blood acid-base status. (2) Introduction of the carbonic anhydrase inhibitor, diamox into anemic fish produced a severe acid-base disturbance associated with a fall in observed carbon dioxide excretion. (3) Isolated perfused gill preparations excrete carbon dioxide at rates comparable to those observed in vivo from free swimming fish. (4) Carbon dioxide excretion in isolated gill preparations is abolished by diamox. The excretion of carbon dioxide in fish occurs via the movement of plasma bicarbonate into the branchial epithelium, where it is subsequently dehydrated into molecular carbon dioxide and excreted. A model is proposed and supportive evidence presented to account for the coupling of ionic exchange occurring across the gill with carbon dioxide excretion. The proposed model distinguishes between control of plasma hydrogen ion activity and regulation of plasma total carbon dioxide concentration per se. The functional significance of this pattern of carbon dioxide excretion for aquatic animals is discussed along with the implications for air breathing fish.

title: From Governess to Wife: How Women on the Fringe of Society Upset and Restore Victorian Homes
Creators: name: Torgersen, Elsa C.
Publisher: name: Utah State University
Year: 2021

description: In middle-class Victorian homes, wives were responsible for the care of the home, the raising of children, and the maintenance and upward mobility of her family’s social standing. She was the heart of the home and her purity and commitment to the home would not only affect her family, but also society. Yet the women who were qualified according to societal standards were a small group, carefully chosen to maintain the standards of society. In the novels Bleak House and Jane Eyre, the authors push back against strict societal expectations. They ask the audience to consider if women should be qualified for this role based on their actions, not their social status. Utilizing the role of the governess, they support the importance of the angel in the home while subverting the belief that only women of a certain social standing are qualified to repair homes.

description: Use of robotic infrastructures can significantly increase with remote access. This would open up the possibility to use costly equipment without the need to buy them, or to simply access those assets remotely when actual travel is not possible or recommended - for example in pandemic times. In this paper we present an analysis of several networking techniques which allow remote robotics operations, alongside with experimental results with distance ranging from hundreds of meters up to thousands of kilometers.
