description: Space PV power needs, driven by LEO constellations and HAPS (High-Altitude Platform Station) are significantly increasing, deeply changing the game in terms of volume and cost requirements. Adaptation of terrestrial PV technology for space application appears then as a potential solution for these industrial and economical challenges. In terms of architecture, the terrestrial PV A uses a single frontsheet covering several strings of cells embedded in adhesive films and assembled in one single step using lamination. This approach is industrially mature, suppresses the risk of electrostatic discharges (triple points) and offers compatibility with several type of materials and solar cells technologies: qualified III-V [2], Commercial-Off-The-Shelf (COTS) Silicon, and emerging Perovskites. In addition, this approach offers room for increased specific power (W/m2), as illustrated in terrestrial PV where efficiency cells to module ratio beyond 90 % are reported. In terms of materials, the introduction of COTS components is highly expected provided that performance compromises can be found. In that sense, radiation and thermal cycling are key ageing tests in the selection process. Experimental results of electrons COTS Si cells irradiations (!Me V) and thermal cycles on laminated Si PVA coupons (140/+ 140 C) are presented. The experimental results of Si PV A thermal cycling will be analyzed with insights from thermo-mechanical simulations of the cells interconnects behavior. Careful design and selection of COTS Si PV A components allows to reach EOL AMO efficiencies for LEO in the 10-14% range, with a stable performance demonstrated over~ 2000 cycles so far; improvement paths will be discussed.
Artist's Statement and Poems

description: Laura Passin’s powerful artist’s statement offers signposts for our reading of her poetry in which clear-cut distinctions between health and illness dissolve and the speaker straddles the divides of Susan Sontag’s famous “kingdom of the sick and kingdom of the well” (3), as Passin locates herself “with one foot in both kingdoms, not certain in which one my center of gravity leans.” Her work is at once deeply subjective, personal and intimate, as well as political. It prompts us to reflect on the role of the poet as interpreter—of others unable to speak for themselves and of one’s own, at times fragile and utterly temporary, citizenship in Sontag’s kingdom of the well. In doing so, it raises pivotal questions of authority. (Tanja Reiffenrath and Gesine Wegner “Dis-eased: Critical Approaches to Disability and Illness in American Studies”)

description: Ionic liquids are the base for electrospray propulsion. We have selected seven liquids to characterize them using an externally wetted electrospray thruster. These are EMI-BF4, EMI-DCA, EMI-Im, EMI-SCN, EMI-EtOSO3 , EMI-Off and EMI-TFA. This research marks the first time that the latter four liquids are reported for externally wetted emitters. A complete thruster assembly has been tested with each of the propellants. Using time-of-flight mass spectrometry, the performance of these ionic liquids has been characterized, assessing thrust, specific impulse and thrust efficiency. EMI-BF4, EMI-DCA and EMI-SCN were found to operate in pure ionic regime while EMI-Im, EMI-EtOSO3, EMI-OTf and EMI-TFA operate in mixed regime.
Iranian Marital Traditions and Women's Rights in Australia: Unpacking the Tension Between Culture and Human Rights Law

Year: 2021
Subjects: Other law and legal studies not elsewhere classified

description: Australia is failing to protect the right of Australian women of Iranian descent to enter into marriage with free and full consent. Interviews with Iranian women living in Australia reveal the extent to which traditional and cultural pressures to marry arguably violate human rights law. This research aims investigates the relationship between human rights and the rules and traditions pertaining to Iranian marital customs. Using a qualitative methodology, this research examines how cultural and religious expectations surrounding marriage erode Iranian women’s right to consent in a free and full manner. In approaching this issue, this research will be concentrating on the views surrounding marriage, and in particular, how traditional Iranian marital customs and religious practices impact on contemporary understandings of marriage and ultimately intersect with international human rights norms, in particular, women’s rights.
First-principles study of multi-control graphene doping using light-switching molecules

description: The high carrier mobility in graphene promises its utility in electronics applications. Azobenzene is a widely studied organic molecule for switchable optoelectronic devices that can be synthesized with a wide variety of ligands and deposited on graphene. Using first-principles calculations, we investigate graphene doping by physisorbed azobenzene molecules with various electron-donating and -accepting ligands. We confirm previous experimental results that demonstrate greater p-doping of graphene for the trans compared to cis configuration when using a SO$_3$ electron-accepting ligand, however we find that NO$_2$ ligands maximize the p-doping difference between isomers. We also examine how these doping effects change when the graphene monolayer is supported on a silica substrate. We then extend these findings by examining the doping effects of an applied electrical bias and mechanical strain to the graphene, which lead to changes in doping for both the trans and cis isomers. These results demonstrate a new type of multi-control device combining light, electric field, and strain to change carrier concentration in graphene.

description: For many plasma physics problems, three-dimensional and kinetic effects are very important. However, such simulations are very computationally intensive. Fortunately, there is a class of problems for which there is nearly azimuthal symmetry and the dominant three-dimensional physics is captured by the inclusion of only a few azimuthal harmonics. Recently, it was proposed [A. Lifschitz et al., J. Comp. Phys. 228 (5) (2009) 1803-1814] to model one such problem, laser wakefield acceleration, by expanding the fields and currents in azimuthal harmonics and truncating the expansion after only the first harmonic. The complex amplitudes of the fundamental and first harmonic for the fields were solved on an r-z grid and a procedure for calculating the complex current amplitudes for each particle based on its motion in Cartesian geometry was presented using a Marder's correction to maintain the validity of Gauss's law. In this paper, we describe an implementation of this algorithm into OSIRIS using a rigorous charge conserving current deposition method to maintain the validity of Gauss's law. We show that this algorithm is a hybrid method which uses a particles-in-cell description in r-z and a gridless description in $ϕ$. We include the ability to keep an arbitrary number of harmonics and higher order particle shapes. Examples, for laser wakefield acceleration, plasma wakefield acceleration, and beam loading are also presented and directions for future work are discussed.

description: Electrospray thrusters rely on a high voltage gain power converter for extracting and accelerating the ions producing thrust. Enhancement of the converter\'s efficiency in space applications is essential since it avoids oversizing the power generation or storage system and it mitigates issues related to the power losses heat dissipation. The paper presents the DCM Forward-Flyback converter integrated with two fifth-order Cockcroft-Walton voltage multipliers for generating positive and negative high-voltage rail for electrospray thrusters. This topology has a reduced component count, is small in size, and is lightweight. Switching losses are minimized by implementing a valley-switching strategy to achieve ZVS. The theoretical analysis is validated with simulation and experimental results.

description: The questions of who has the right and authority to write about disability—and what this writing could look like—echo in the works which poet and disability scholar Kenny Fries contributes to this thematic issue. His artist’s statement poignantly reminds us of the cultural cliché “where I am the only visibly disabled writer and if I don’t bring up the subject nobody else will.” His poems challenge us to move beyond the surface level and enter the very “microcosms” Fries discerned in Japanese Gardens. Purposefully, we included a wide array of poems, some specifically and explicitly about disability, others soliciting us to “excavate” and interrogate images and metaphors at work in both the representation and experience of disability.

Revolution and Cure: Molyneux’s Problem, Denis Diderot’s Letter on the Blind, and Royall Tyler’s The Algerine Captive
Creators: name: Sydlik, Andrew
Publisher: name: Current Objectives of Postgraduate American Studies
Year: 2018

description: This essay traces the influence of Enlightenment philosophy, specifically Denis Diderot’s Letter on the Blind, on Royall Tyler’s American novel The Algerine Captive. Focusing on the largely overlooked role of disability in the novel, I argue that The Algerine Captive reflects a medical and moral model of disability that draws on Diderot’s representation of blindness as a biological defect and a moral lack. Tyler explores American anxieties over whether the new nation would survive the political divisions pervading the country following the Revolutionary War. While sympathy was touted as a means of unity by both political leaders and authors, Diderot’s Letter and Tyler’s The Algerine Captive reflect the view of blindness as a disruption to sympathy. I interrogate this framework to show how it promotes the necessity of medical and moral intervention to enable both sight and sympathy. According to the novel, sympathy, like sight, can only be achieved through proper training, by learning to “see” others, and the supposed equality and freedoms of America, correctly.

description: The black hole final state proposal implements manifest unitarity in the process of black hole formation and evaporation in quantum gravity, by postulating a unique final state boundary condition at the singularity. We argue that this proposal can be embedded in the gauge/gravity context by invoking a path integral formalism inspired by the Schwinger-Keldysh like thermo-field double construction in the dual field theory. This allows us to realize the gravitational quantum channels for information retrieval to specific deformations of the field theory path integrals and opens up new connections between geometry and information theory.

“Sing[ing] of the Middle Way:” Michael McClure’s Venture for a New Mode of Thought Between Science and Mysticism
Creators: name: Benz, Stefan

Year: 2018
Subjects: Michael McClure; Poetry; Epistemology; Moiré Effect; Natural Science; Mysticism

description: This article examines the epistemological concerns of Michael McClure’s poem “Double Moire for Francis Crick” (2010). Beyond showcasing McClure’s persistent interest in the natural sciences as well as in the Chinese and Japanese mystical traditions, this poem lyrically appropriates the physical phenomenon of the moiré effect and thereby exemplifies how a cooperation between these different modes of thought is profitable and necessary to reform established ways of knowledge production. Via a close reading of the poem’s borrowings from paleontology, microbiology, evolutionary biology, and its appropriations of Taoism and Zen Buddhism, this article discusses the dimensions and scope of McClure’s epistemological endeavor. Significantly, “Double Moire for Francis Crick” does not synthesize the two presented perspectives into one but overlays these to create a third combined structure which is ‘between’ the original structures of natural science and mysticism, allowing for a combination and alignment of insight produced in either mode of thought.

description: Extended Reality (XR) technology is transforming the way to interact with the surrounding world, and the aviation industry is no exception. In airport control towers, XR can be exploited to overlay all the auxiliary information needed with the real-world data supporting the controllers during their operations without forcing them to continuously scan data on head-down displays and switch between the primary head-up out-of-the-tower visual field and the auxiliary head-down equipment, with a benefit in terms of workload and situational awareness, and lowering the risk of not detecting unpredictable situations. With the same aim of improved situational awareness, synthetic Safety Nets can be integrated with the out-ofthe-tower view to guide the controller\'s attention toward alerting situations. An operational concept for attention guidance through the usage of Extended Reality Safety Nets based on visual and auditory cues in airport control towers is developed for the simulated scenario of Bologna Airport in Italy. To assess whether and how the air traffic controllers\' Human Performances benefit from the introduction of XR Safety Nets, a human-in-the-loop technical test involving experienced air traffic controllers is executed. The outcome of the simulation test proves how the proposed solution effectively reduces both the time the controllers need to notice and react to a safety event and the number of switches between the head-up and head-down positions. Moreover, the controllers report a positive impact on the potential for human error, a benefit for situational awareness, and enhanced team situational awareness.

description: The relative abundances of carbon and oxygen have long been recognized as fundamental diagnostics of stellar chemical evolution. Now, the growing number of exoplanet observations enable estimation of these elements in exoplanetary atmospheres. In hot Jupiters, the C/O ratio affects the partitioning of carbon in the major observable molecules, making these elements diagnostic of temperature structure and composition. Here we present measurements of carbon and oxygen abundances in 16 stars that host transiting hot Jupiter exoplanets, and compare our C/O ratios to those measured in larger samples of host stars, as well as those estimated for the corresponding exoplanet atmospheres. With standard stellar abundance analysis we derive stellar parameters as well as [C/H] and [O/H] from multiple abundance indicators, including synthesis fitting of the [O I] 6300 Å line and NLTE corrections for the O I triplet. Our results, in agreement with recent suggestions, indicate that previously-measured exoplanet host star C/O ratios may have been overestimated. The mean transiting exoplanet host star C/O ratio from this sample is 0.54 (C/O$_{solar}$=0.54), versus previously-measured C/O$_{host~star}$ means of $\sim$0.65-0.75. We also observe the increase in C/O with [Fe/H] expected for all stars based on Galactic chemical evolution; a linear fit to our results falls slightly below that of other exoplanet host stars studies but has a similar slope. Though the C/O ratios of even the most-observed exoplanets are still uncertain, the more precise abundance analysis possible right now for their host stars can help constrain these planets' formation environments and current compositions.

description: The ‘we’ narrator has been witnessing an apparent upswing in 21st-century U.S. fiction. Yet, still only a comparably small number of context-focused analyses have discussed this narrative voice so far. Further, inquiries into analyses of the ‘we’ narrator’s cultural and political implications have been repeatedly limited by an underlying association of narratives in the first-person plural with discursive acts of protest and resistance. Integrating text-centered and contextual approaches to the ‘we’ narrative voice, I draw on two examples, Joshua Ferris’s Then We Came to the End and TaraShea Nesbit’s The Wives of Los Alamos, to propose that, in a contemporary U.S. context, this narrative voice is intertwined with both, the representation of counter-voices to dominant discourses and the allegorical reaffirmation of fundamental American myths pertinent to U.S. society and culture.

description: Electrospray propulsion is gaining popularity due to its high efficiency at low power, the use of inert liquid propellants, and near-instantaneous operations. Externally wetted electrosprays, in particular, can operate in different emission regimes, which yields different performance points. Real-time dynamic switching between these regimes could enable variable-performance maneuvers, leading to propellant and duration savings. This study focuses on the optimization of variable-performance electrospray maneuvers for small satellites in LEO. The methodology employs a genetic algorithm to select the set point depending on a maneuvering efficiency term, aimed at minimizing multiple objectives. A numerical example demonstrates the benefits of this approach, presenting practical considerations regarding operations.

Water retention of rigid soils from a two-factor model for clay
Creators: name: Chertkov, V. Y.
Publisher: name: arXiv
Year: 2014
Subjects: subject: Geophysics (physics.geo-ph)
subject: FOS: Physical sciences

description: Water retention is one of the key soil characteristics. Available models of soil water retention relate to the curve-fitting type. The objective of this work is to suggest a physical model of water retention (drying branch) for soils with a rigid matrix. "Physical" means the prediction based on the a priori measured or estimated soil parameters with a clear physical meaning. We rely on the two-factor model of clay that takes into account the factors of capillarity and shrinkage. The key points of the model to be proposed are some weak pseudo shrinkage that the rigid soils demonstrate according to their experimental water retention curves, and some specific properties of the rigid grain matrix. The three input parameters for prediction of soil water retention with the rigid grain matrix include inter-grain porosity, as well as maximum and minimum grain sizes. The comparison between measured and predicted sand water retention curves for four different sands is promising.

description: With a world-class graphite project in Tanzania (East Africa), The Pula Group, LLC is committed to a greener future. The high-quality graphite mineralization includes jumbo flakes developed to a depth of 60 meters, a key driver ensuring the project economics are strong. The Pula graphite deposits are extensions of the Nachu graphite deposits. PGP is taking a modular approach to mining and processing graphite, an innovative and efficient approach to optimize the success of the project during the ramp-up phase. This adaptive approach to mining helps mitigate economic risk and the "too big to fail" attitude that has sunk many large-scale mining projects. The PGP model provides a clear way to reignite the capacity for junior mining companies to activate the sector with minimal risk and maximum benefit to communities. Along with the high caliber of its Tanzanian graphite opportunity, The Pula Group, a U.S.-based company, is setting high ethical standards in the mining sector. The Group's subsidiary for developing the project is Pula Graphite Partners (PGP), a 50-50 joint venture with local strategic partners. Even during the exploration phase, PGP already has a superior track record of philanthropy.

description: Hot astrophysical plasma is ubiquitous in the Universe, from comets in our Solar system to the largest scale structures -- the cosmic web filaments. These hot plasmas, with the temperature of a few millions of degrees, are often observed in the X-ray wavelength range. Spectroscopic diagnostics enable us to probe physical properties like temperature, density, abundance, microscopic turbulence, the line of sight velocity, etc. High resolving power is essential to overcome the confusion caused by unresolved spectral features. Thanks to the grating spectrometers aboard XMM-Newton and Chandra, our knowledge of the hot and energetic Universe are advanced. Meanwhile, high-quality spectra from current and future generations of X-ray spectrometers also challenge plasma models that are widely used in the community. More complete and accurate atomic data are required to improve plasma models. Suitable management of the ever-growing atomic data is also important. This thesis starts with the updates of radiative recombination data in the spectral analysis package SPEX, where various plasma models built on the atomic database are available. The updated plasma models are then used to better understand the physics of circumnuclear media in NGC 5548 and NGC 3783, as well as the nitrogen enrichment in the intracluster media.
“Here They Come to Save the Day” – The New Sincerity in 1990s American Superhero Comics

description: After the success of postmodern superhero comics that deconstructed heroism in post-Vietnam, post-Watergate USA, mid-1990s comics experienced a resurgence in unabashedly heroic narratives. This coincided with David Foster Wallace’s call for post-irony and the emergence of New Sincerity, a post-postmodern trend that aims to break with cynicism. I will argue that these superhero comics are inherently nostalgic, drawing on tropes, storylines, and characters from the Silver Age comics of the 1950s and 60s. Discussing this dispute between postmodern cynicism and New Sincerity, a lens through which the current political and cultural landscape can be analyzed and dissected, will shed light on the origin and nature of two opposing narrative trends that have been increasingly shaping American culture, society, and politics.

description: This article examines the politics of mainstream videogames in the contemporary political moment in the United States. To illustrate the political agency of videogames, the paper first considers the entanglements of videogames and gamer culture in the anti-progressive backlash that has accompanied Donald Trump’s presidential campaign and presidency by looking at the GamerGate harassment campaign. The article then provides a critical reading of Ubisoft’s Far Cry 5 (2018), which demonstrates how the videogame (re)produces reactionary ideologies. Far Cry 5 repeatedly employs tropes and narratives steeped in American colonialism, expresses a yearning for the past and its way of life, and works through a logic of taking back the country under the feeling of having one’s home taken away by strangers. As it thus evokes a sense of ‘making America great again,’ Far Cry 5 exemplifies the political resonance of videogames in the ongoing phenomenon of Trumpism in the United States.

A study of the location and size of the actuators is performed as well, analyzing the impact on the performance of the controller in achieving and maintaining the desired attitude. The performance is evaluated in terms of power, propellant consumption and pointing error, showing how the robust controller can reject external disturbances and deal with model uncertainties.

description: Invertebrates are important for restoration processes as they are key drivers of many landscape-scale ecosystem functions; including pollination, nutrient cycling and soil formation. However, invertebrates are often overlooked in restoration monitoring be-cause they are highly diverse, poorly described, and time-consuming to survey, and require increasingly scarce taxonomic expertise to enable identification. DNA meta-barcoding is a relatively new tool for rapid survey that is able to address some of these concerns, and provide information about the taxa with which invertebrates are inter-acting via food webs and habitat. Here, we evaluate how invertebrate communities may be used to determine ecosystem trajectories during restoration. We collected ground- dwelling and airborne invertebrates across chronosequences of mine-site restoration in three ecologically disparate locations in Western Australia and identi-fied invertebrate and plant communities using DNA metabarcoding. Ground-dwelling invertebrates showed the clearest restoration signals, with communities becoming more similar to reference communities over time. These patterns were weaker in airborne invertebrates, which have higher dispersal abilities and therefore less local fidelity to environmental conditions. Although we detected directional changes in community composition indicative of invertebrate recovery, patterns observed were inconsistent between study locations. The inclusion of plant assays allowed identifica-tion of plant species, as well as potential food sources and habitat. We demonstrate that DNA metabarcoding of invertebrate communities can be used to evaluate res-toration trajectories. Testing and incorporating new monitoring techniques such as DNA metabarcoding is critical to improving restoration outcomes.
Memory, Identity and Political Communities – The Discursive Construction of the Transatlantic Alliance
Creators: name: Sporys, Sarah
Publisher: name: Current Objectives of Postgraduate American Studies

Subjects: Memory; U.S.; Europe; Transatlantic Relations; Discourse; Community; Transatlantic Memory Community

description: The transatlantic community has, from its inception, been described as a community of like-minded nations that is held together not only by interests but also by shared values. These are based on a common identity – of what Karl W. Deutsch has called a “we-feeling” (36). Memory is a binding factor for both national and international communities because it contributes to their self-understanding in the present and is indispensable for imagining a common future. Given this assumption, this paper uses theories of memory as an analytical tool for studying the transatlantic partnership. More specifically, this paper will introduce the term and concept of a “transatlantic memory community” which is developed from Maurice Halbwachs’s concept of collective memory. It is based on the idea that the members of the Atlantic Community have developed a shared understanding of the past due to their membership in this political and ideational community. The analysis of the historical framing of the Bosnian conflict in Germany, France and the United States (U.S.) will serve as an example of the development of mnemonical commonplaces in the Atlantic Alliance.

Augmented base loci and restricted volumes on normal varieties, II: The case of real divisors
Creators: name: Lopez, Angelo Felice
Publisher: name: arXiv

Subjects: subject: Algebraic Geometry (math.AG)
subject: FOS: Mathematics

description: Let $X$ be a normal projective variety defined over an algebraically closed field and let $Z$ be a subvariety. Let $D$ be an $\mathbb R$-Cartier $\mathbb R$-divisor on $X$. Given an expression $(\ast) \ D \sim_{\mathbb R} t_1 H_1 + \ldots + t_s H_s$ with $t_i \in \mathbb R$ and $H_i$ very ample, we define the $(\ast)$-restricted volume of $D$ to $Z$ and we show that it coincides with the usual restricted volume when $Z \not\subseteq \mathbf{B}_+(D)$. Then, using some recent results of Birkar (arXiv:1312.0239), we generalize to $\mathbb R$-divisors the two main results of arXiv:1305.4284 by Boucksom, Cacciola and the author: The first, proved for smooth complex projective varieties by Ein, Lazarsfeld, Mustaţă, Nakamaye and Popa, is the characterization of $\mathbf{B}_+(D)$ as the union of subvarieties on which the $(\ast)$-restricted volume vanishes; the second is that $X - \mathbf{B}_+(D)$ is the largest open subset on which the Kodaira map defined by large and divisible $(\ast)$-multiples of $D$ is an isomorphism.

description: This paper presents a novel design methodology for optimal transmission policies at a smart sensor to remotely estimate the state of a stable linear stochastic dynamical system. The sensor makes measurements of the process and forms estimates of the state using a local Kalman filter. The sensor transmits quantized information over a packet dropping link to the remote receiver. The receiver sends packet receipt acknowledgments back to the sensor via an erroneous feedback communication channel which is itself packet dropping. The key novelty of this formulation is that the smart sensor decides, at each discrete time instant, whether to transmit a quantized version of either its local state estimate or its local innovation. The objective is to design optimal transmission policies in order to minimize a long term average cost function as a convex combination of the receiver's expected estimation error covariance and the energy needed to transmit the packets. The optimal transmission policy is obtained by the use of dynamic programming techniques. Using the concept of submodularity, the optimality of a threshold policy in the case of scalar systems with perfect packet receipt acknowledgments is proved. Suboptimal solutions and their structural results are also discussed. Numerical results are presented illustrating the performance of the optimal and suboptimal transmission policies.

description: The surge in small satellite constellations is spurred by the recent cost reductions in launching capabilities. This has facilitated the development of affordable constellations in Low Earth Orbit (LEO). Commercial space components are revolutionizing LEO systems, with a particular focus on electric propulsion. Deployment strategies and space mobility are also gaining significant attention. To ensure a successful constellation deployment, careful consideration should be given to factors such as launcher selection. A proposed concurrent engineering methodology utilizes optimization techniques to identify optimal combinations of launchers, propulsion systems, and deployment strategies. The methodology is demonstrated through a constellation deployment scenario, showcasing its effectiveness.

description: Biomass has become one of the important commercial material to produce value added products. We have developed a lab-scale batch microwave system to convert biomass into fuel. The quantity and quality of product was analyzed and the parameters affecting them were studied. We have also modeled and simulated both conventional and microwave heating process to observe the heating characteristic and product quantity. Importantly, we have managed to solve the problem of temperature measurement under microwave heating by avoiding the direct contact of temperature sensor with microwave irradiation. Challenges related to microwave processing of solid waste materials are presented.

description: We explore the possibility to generate new parity symmetry in the quantum Rabi model after a bias is introduced. In contrast to a mathematical treatment in a previous publication [J. Phys. A 46, 265302 (2013)], we consider a physically realistic method by involving an additional spin into the quantum Rabi model to couple with the original spin by an Ising interaction. The rule can be found that the parity symmetry is broken by introducing a bias and then restored by adding new degrees of freedom. Experimental feasibility of realizing the models under discussion is investigated.
