description: H-wave is an open-source software package for performing the Hartree--Fock approximation (HFA) and random phase approximation (RPA) for a wide range of Hamiltonians of interacting fermionic systems. In HFA calculations, H-wave examines the stability of several symmetry-broken phases, such as anti-ferromagnetic and charge-ordered phases, in the given Hamiltonians at zero and finite temperatures. Furthermore, H-wave calculates the dynamical susceptibilities using RPA to examine the instability toward the symmetry-broken phases. By preparing a simple input file for specifying the Hamiltonians, users can perform HFA and RPA for standard Hamiltonians in condensed matter physics, such as the Hubbard model and its extensions. Additionally, users can use a Wannier90-like format to specify fermionic Hamiltonians. A Wannier90 format is implemented in RESPACK to derive ab initio Hamiltonians for solids. HFA and RPA for the ab initio Hamiltonians can be easily performed using H-wave. In this paper, we first explain the basis of HFA and RPA, and the basic usage of H-wave, including download and installation. Thereafter, the input file formats implemented in H-wave, including the Wannier90-like format for specifying the interacting fermionic Hamiltonians, are discussed. Finally, we present several examples of H-wave such as zero-temperature HFA calculations for the extended Hubbard model on a square lattice, finite-temperature HFA calculations for the Hubbard model on a cubic lattice, and RPA in the extended Hubbard model on a square lattice.

description: Die evangelisch-theologische Fakultät der Martin-Luther-Universität Halle-Wittenberg veranstaltet jeweils zu Beginn des Wintersemesters eine «Theologische Woche»: Ein gemeinsames Thema wird von verschiedenen Seiten in Vorträgen, Seminarveranstaltungen und Podiumsdiskussionen beleuchtet. Die Theologische Woche richtet sich hicht nur an Theologiestudierende, sondern auch an Interessierte aus der Stadt und den Kirchgemeinden. «Utopieverlust und Reich-Gottes-Erwartung» war das Thema der Theologischen Woche 1994. Ina Praetorius hielt am 17. Oktober den hier wiedergegebenen Eröffnungsvortrag. Die Autorin beharrt auf ihrer feministischen Utopie: Das Ausgeschlossensein der Frauen aus der androzentrischen Ordnung gewährt zugleich einen immensen Freiraum. Hier lassen sich Umwertungsprozesse einleiten und realpolitische Forderungen begründen. Für den Mann beginnt die Utopie dort, wo er die Ordnung durchschaut, die angeblich in seinem eigenen Interesse funktioniert, derweil sie sein Leben ärmer, ja armselig macht.

description: Endometriosis is an inflammatory condition that is associated with progesterone resistance and cell proliferation, resulting in pain, infertility and pregnancy loss. We previously demonstrated phosphorylation of STAT3 in eutopic endometrium of infertile women with this disorder leading to over-expression of the oncogene BCL6 and stabilization of hypoxia-induced factor 1 alpha (HIF-1α). Here we report coordinated activation of KRAS and over-expression of Sirtuin 1 (SIRT1), a histone deacetylase and gene silencer, in the eutopic endometrium from women with endometriosis throughout the menstrual cycle. The mice with conditional activation of KRAS in the PGR positive cells reveal an increase of SIRT1 expression in the endometrium compared to control mice. The expression of progesterone receptor target genes including the Indian Hedgehog pathway genes are significantly down-regulated in the mutant mice. SIRT1 co-localizes with BCL6 in the nuclei of affected individuals and both proteins bind to and suppress the promoter of GLI1, a critical mediator of progesterone action in the Indian Hedgehog pathway, by ChIP analysis. In eutopic endometrium, GLI1 expression is reduced in women with endometriosis. Together, these data suggest that KRAS, SIRT1 and BCL6 are coordinately over-expressed in eutopic endometrium of women with endometriosis and likely participate in the pathogenesis of endometriosis.

description: The availability of data on digital traces is growing to unprecedented sizes, but inferring actionable knowledge from large-scale data is far from being trivial. This is especially important for computational finance, where digital traces of human behavior offer a great potential to drive trading strategies. We contribute to this by providing a consistent approach that integrates various datasources in the design of algorithmic traders. This allows us to derive insights into the principles behind the profitability of our trading strategies. We illustrate our approach through the analysis of Bitcoin, a cryptocurrency known for its large price fluctuations. In our analysis, we include economic signals of volume and price of exchange for USD, adoption of the Bitcoin technology, and transaction volume of Bitcoin. We add social signals related to information search, word of mouth volume, emotional valence, and opinion polarization as expressed in tweets related to Bitcoin for more than 3 years. Our analysis reveals that increases in opinion polarization and exchange volume precede rising Bitcoin prices, and that emotional valence precedes opinion polarization and rising exchange volumes. We apply these insights to design algorithmic trading strategies for Bitcoin, reaching very high profits in less than a year. We verify this high profitability with robust statistical methods that take into account risk and trading costs, confirming the long-standing hypothesis that trading based social media sentiment has the potential to yield positive returns on investment.

description: Research Question: In response to calls for additional research on brand governance in sports, we examine brand governance practices in the novel and under researched context of the World Rugby Sevens Series. In doing so, we expand the discourse on rugby in the 21st century and provide fresh insights regarding the brand governance practices in an international recurring sporting event. Research methods: Our qualitative case study design utilizes in-depth interviews with eight rugby senior executives representing seven rugby unions. Using the constant comparison technique and reflexive thematic analysis, we identify nine key themes to illustrate brand governance as it relates to the World Rugby Sevens Series. Results and findings: The first three themes, which serve as a prelude to a deeper discussion of brand management practices depict World Rugby Sevens Series as a distinct, rebellious-responsible, co-created sportainment brand. Fostering close and beneficial exchanges with brand partners, developing strong collaborative ties with host cities and venues, commitment to athlete performance through care and support, adoption of strategic corporate social responsibility to enhance the brand, championing brand co-creation, and activating social media use are the brand governance practices on which the World Rugby Sevens Series is built. Implications: We provide a fine-grained exposition of branding from the brand owner’s perspective. For the World Rugby Sevens Series, brand governance requires the ability to collaborate with and serve the needs of key stakeholders including global partners, local sponsors, rugby unions, host cities and venues, athletes, and fans.

description: We propose simultaneous confidence bands of the hyperbolic-type for the contrasts between several nonlinear (curvilinear) regression curves. The critical value of a confidence band is determined from the distribution of the maximum of a chi-square random process defined on the domain of explanatory variables. We use the volume-of-tube method to derive an upper tail probability formula of the maximum of a chi-square random process, which is asymptotically exact and sufficiently accurate in commonly used tail regions. Moreover, we prove that the formula obtained is equivalent to the expectation of the Euler-Poincare characteristic of the excursion set of the chi-square random process, and hence conservative. This result is therefore a generalization of Naiman's inequality for Gaussian random processes. As an illustrative example, growth curves of consomic mice are analyzed.

description: The National Freshwater Ecosystem Priority Area (NFEPA) Project highlights that priority rivers need to be conserved in South Africa to secure the sustainability of freshwater resources. This research aims to interrelate stakeholder views to promote collaborative stakeholder protection of the Crocodile and Sabie Rivers. By exploring stakeholder views of the NFEPA project, relevant stakeholder platforms and stakeholder roles and relationships relating to river protection, this research enhances understanding of the implementation of national water policy at local level. It is proposed that over time, an adaptive local governance system will promote collaborative stakeholder protection of the Crocodile and Sabie Rivers.

description: We perform two-pion Hanbury Brown-Twiss (HBT) interferometry for the partially coherent pion-emitting sources in relativistic heavy-ion collisions, using a multi-phase transport (AMPT) model. A longitudinal coherent emission length, as well as a transverse coherent emission length, are introduced to the pion generation coordinates in calculating the HBT correlation functions of the partially coherent sources. We compare the model results with and without coherent emission conditions with experimental data in Au-Au collisions at center-of-mass energy $\sqrt{s_{NN}}=$200 GeV, and in Pb-Pb collisions at center-of-mass energy $\sqrt{s_{NN}}=$2.76 TeV, and find that the HBT results of the partially coherent sources are closer to the experimental data than those of chaotic sources.

A meaty problem: how people think about the morality of meat
Creators: name: LUCY ANN MARY MAYNE
Publisher: name: Monash University

Subjects: subject: Philosophy
subject: FOS: Philosophy, ethics and religion

description: This thesis explores moral psychology, moral motivation, and the role of social norms in explaining why people tend to be confident their meat eating is morally justified despite relying on internally inconsistent arguments, and why people tend not to be motivated to stop eating meat even if they become intellectually convinced they should. Analysing the moral psychology of meat eating reveals a lack of motivation to stop eating meat is not just a failure of reason, affect, or motivation. Rather, it is at least partially a product of both empirical and normative expectations about the people with whom one interacts.

Petitioning 'John Company': Women and the English East India Company, 1600-1635.
Creators: name: ERIN GAYE SMITH
Publisher: name: Monash University
Year: 2018
Subjects: History

description: This thesis examines how ordinary women, wives, widows, mistresses, sisters and nieces, negotiated the political and economic bureaucracy of the English East India Company in the first three decades of the seventeenth century. It focuses on hundreds of previously neglected petitions presented to the Court of Committees, the organisation's governing body, by women, between 1600 and 1635. By analysing these documents, the nature of these women's requests and how the Company responded, this thesis sheds new light on an organisation that has been viewed almost exclusively in terms of its male employees.

description: The Adam Smith Institute is a British think tank that is known for its aggressive advocacy of neoliberalism and links to Margaret Thatcher. Existing studies have concluded that the ASI’s influence was part of a larger collective that challenged the wisdom of the post-war consensus. This thesis seeks to examine an overlooked aspect of the ASI – its strategies. It will argue that in mapping the evolution of the ASI’s strategies over the past forty years, new conclusions can be drawn about its individual contribution to British political life, namely, its importation of a new think tank model from the US.

description: This thesis explores the Islamic State, known as ISIS, with the aim of determining whether ISIS ascribes to the existing waves and frameworks of terrorism, or whether its pursuit of statehood and governance constitutes an evolving or uniquely new wave. The work of David Rapoport is consulted to examine the established first four waves of terrorism and their relation to ISIS. The fifth wave framework proposed by Jeffrey Kaplan is also explored in terms of its application to ISIS. The Islamic State’s ideology of jihad, or jihadology, as well as its campaign of nation-building, testify to the evolution and transformation of this organisation from pre-existing theories and waves of terrorism to justifying a new wave on its own.

description: Social media is increasingly an essential part of community building. This thesis seeks to understand how the online world mediates marginalized community identity. The examples examined are the respective communities around the Twitter hashtag movements #NotYourAsianSidekick, #CancelColbert, and #SolidarityIsForWhiteWomen. A key focus is the maintenance and patrolling of community boundaries in online spaces. However, this carries its own dangers, such as when community members are excluded because they do not fit a community’s ideals. By comparing and contrasting the events surrounding the aforementioned hashtag movements, I hope to elucidate what coming together as a community in an online space entails.

description: Adults who experience an acquired brain injury often experience disorders of consciousness, physical difficulties, and maladaptive behaviours. Multimodal sensory therapy may benefit brain injured patients, however the extent this therapy can facilitate rehabilitation is not well understood. This systematic review aimed to synthesize multimodal sensory therapy research for adults affected by acquired brain injury. PRISMA guidelines were followed and searches for work published up until July 2021 were undertaken in 5 databases, finding 1054 articles. 43 articles were included in the study. Results describe 29 studies related to coma following an acquired brain injury and 14 to no coma studies (mostly stroke). Multimodal sensory therapy was mostly used as a coma arousal technique following traumatic brain injury, finding positive effects. Multimodal sensory therapy was less applied in stroke, no coma rehabilitation, where most studies found improvement in somatosensory sensation and motor control in an affected limb. In several no coma studies, effects were maintained after several months. The most common senses stimulated in coma studies were audio (N = 30), tactile (N = 28), visual (N = 26), olfactory (N = 22), and gustatory (N = 17), while the most common senses stimulated in stroke, no coma studies were proprioception (N = 7), tactile (N = 8), and stereognosis (N = 4). Multimodal sensory therapy can be beneficial for patients, especially those in a minimally conscious state or attempting physical rehabilitation following stroke. Negative findings are infrequent in the current literature base. Multimodal sensory therapy appears to be a low-risk intervention with positive outcomes.

description: This issue has taken shape within the context of a global pandemic, and despite these challenges it has provided a welcome space to continue our common intellectual work. Our authors hail from around the globe and have each experienced different aspects of this volatility in different ways at different times. The issue features a special collection entitled Trial by Fire. These essays probe and question the underlying assumptions embedded within the initiatory rites of immersive fieldwork, and the personal consequences and costs that fieldworkers sometimes bear. This issue also contains two articles on the complex ethics of collaboration, an interview with the authors of a graphic ethnography, as well as an extract of this work. Taken together, the contributions to this third issue of Commoning Ethnography continue to address the journal’s core provocations. They explore the way in which ethnography exceeds the boundaries of the Academy and connects scholarly knowledge to other intellectual and artistic modes of knowing and doing. And they probe the complex ethics and politics of ethnographic knowledge production in innovated ways.
Modal Analysis Using Sparse and Co-prime Arrays

description: Let a measurement consist of a linear combination of damped complex exponential modes, plus noise. The problem is to estimate the parameters of these modes, as in line spectrum estimation, vibration analysis, speech processing, system identification, and direction of arrival estimation. Our results differ from standard results of modal analysis to the extent that we consider sparse and co-prime samplings in space, or equivalently sparse and co-prime samplings in time. Our main result is a characterization of the orthogonal subspace. This is the subspace that is orthogonal to the signal subspace spanned by the columns of the generalized Vandermonde matrix of modes in sparse or co-prime arrays. This characterization is derived in a form that allows us to adapt modern methods of linear prediction and approximate least squares, such as iterative quadratic maximum likelihood (IQML), for estimating mode parameters. Several numerical examples are presented to demonstrate the validity of the proposed modal estimation methods, and to compare the fidelity of modal estimation with sparse and co-prime arrays, versus SNR. Our calculations of Cramér-Rao bounds allow us to analyze the loss in performance sustained by sparse and co-prime arrays that are compressions of uniform linear arrays.

description: The density in the core of neutron stars can reach values of about 5 to 10 times nuclear matter saturation density. It is, therefore, a natural assumption that hadrons may have dissolved into quarks under such conditions, forming a hybrid star. This star will have an outer region of hadronic matter and a core of quark matter or even a mixed state of hadrons and quarks. In order to investigate such phases, we discuss different model approaches that can be used in the study of compact stars as well as being applicable to a wider range of temperatures and densities. One major model ingredient, the role of quark interactions in the stability of massive hybrid stars is discussed. In this context, possible conflicts with lattice QCD simulations are investigated.

The making of an intrinsic property: “Symmetry heuristics” in early particle physics

description: Mathematical invariances, usually referred to as “symmetries”, are today often regarded as providing a privileged heuristic guideline for understanding natural phenomena, especially those of micro-physics. The rise of symmetries in particle physics has often been portrayed by physicists and philosophers as the “application” of mathematical invariances to the ordering of particle phenomena, but no historical studies exist on whether and how mathematical invariances actually played a heuristic role in shaping microphysics. Moreover, speaking of an “application” of invariances conflates the formation of concepts of new intrinsic degrees of freedom of elementary particles with the formulation of models containing invariances with respect to those degrees of freedom. I shall present here a case study from early particle physics (ca. 1930–1954) focussed on the formation of one of the earliest concepts of a new degree of freedom, baryon number, and on the emergence of the invariance today associated to it. The results of the analysis show how concept formation and “application” of mathematical invariances were distinct components of a complex historical constellation in which, beside symmetries, two further elements were essential: the idea of physically conserved quantities and that of selection rules. I shall refer to the collection of different heuristic strategies involving selection rules, invariances and conserved quantities as the “SIC-triangle” and show how different authors made use of them to interpret the wealth of new experimental data. It was only a posteriori that the successes of this hybrid “symmetry heuristics” came to be attributed exclusively to mathematical invariances and group theory, forgetting the role of selection rules and of the notion of physically conserved quantity in the emergence of new degrees of freedom and new invariances. The results of the present investigation clearly indicate that opinions on the role of symmetries in fundamental physics need to be critically reviewed in the spirit of integrated history and philosophy of science.

description: This piece began as a series of conversations with colleagues about the joys and frustrations I experienced in my endeavours to practice commoning in a new course, ‘Anthropology for Liberation.’ In it, I reflect on my efforts to place pedagogical practices of commoning and decolonising anthropology – critically examining and making space for different ways of learning, knowing, and being – at the centre of our classroom agenda. I go on to discuss how working to untangle the knot of colonialism with my students has been simultaneously the most challenging and the most rewarding aspect of teaching this course. I also examine some of the tensions involved in creating an educational common that encourages dialogue and critique yet sits within a university system built on inherently unequal power relations between lecturer and student. Finally, I reflect on some of the reasons why I was not entirely successful in creating an anthropological community that commons.

description: When the journal launched last year, it was not a culmination, but rather a start: of generative conversations, of relationships with a readership interested in the intrinsic political potential of commoning with/in ethnographic practice. In this volume, we tune in to and amplify questions about ethnographic practice as a form of knowledge production. In particular, we engage with the question put forward in the first volume: “What does combining the idea of commoning with the practice of ethnography allow us to think about or to do that we might not otherwise?” (Elinoff and Trundle 2018: 1). Building on that, here we ask: what if ethnography is a source of commoning differently? This question of commoning differently, also taken up by the articles in this volume, encourages us to engage with emerging scholarship and a politics of uncommoning.

History

description: The reign of King Stephen, a tumultuous time in English history, was a formative period for the bishops of England, as they strove to carve out a role for themselves. This thesis explores how the bishops in the dioceses of York, Hereford, and London asserted their authority during this period. In particular, this thesis argues that during Stephen’s reign, bishops were evolving into a distinct class, needing to negotiate with several competing groups in society, not only the Crown, to exercise their influence.

description: Little cigars (LCs) are regulated differently than cigarettes, allowing them to be potentially targeted at youth/young adults. We exposed human bronchial epithelial cultures (HBECs) to air or whole tobacco smoke from cigarettes vs. LCs. Chronic smoke exposure increased the number of dead cells, lactate dehydrogenase release, and interleukin-8 (IL-8) secretion and decreased apical cilia, cystic fibrosis transmembrane conductance regulator (CFTR) protein levels, and transepithelial resistance. These adverse effects were significantly greater in LC-exposed HBECs than cigarette exposed cultures. LC-exposure also elicited unique gene expression changes and altered the proteomic profiles of airway apical secretions compared to cigarette-exposed HBECs. Gas chromatography-mass spectrometry (GC-MS) analysis indicated that LCs produced more chemicals than cigarettes, suggesting that the increased chemical load of LCs may be the cause of the greater toxicity. This is the first study of the biological effects of LCs on pulmonary epithelia and our observations strongly suggest that LCs pose a more severe danger to human health than cigarettes.

description: White matter microstructure, essential for efficient and coordinated transmission of neural communications, undergoes pronounced development during the first years of life, while deviations to this neurodevelopmental trajectory likely result in alterations of brain connectivity relevant to behavior. Hence, systematic evaluation of white matter microstructure in the normative brain is critical for a neuroscientific approach to both typical and atypical early behavioral development. However, few studies have examined the infant brain in detail, particularly in infants under 3 months of age. Here, we utilize quantitative techniques of diffusion tensor imaging and neurite orientation dispersion and density imaging to investigate neonatal white matter microstructure in 104 infants. An optimized multiple b-value diffusion protocol was developed to allow for successful acquisition during non-sedated sleep. Associations between white matter microstructure measures and gestation corrected age, regional asymmetries, infant sex, as well as newborn growth measures were assessed. Results highlight changes of white matter microstructure during the earliest periods of development and demonstrate differential timing of developing regions and regional asymmetries. Our results contribute to a growing body of research investigating the neurobiological changes associated with neurodevelopment and suggest that characteristics of white matter microstructure are already underway in the weeks immediately following birth.
A Computational Study of a Data Assimilation Algorithm for the Two-dimensional Navier--Stokes Equations

description: We study the numerical performance of a continuous data assimilation (downscaling) algorithm, based on ideas from feedback control theory, in the context of the two-dimensional incompressible Navier--Stokes equations. Our model problem is to recover an unknown reference solution, asymptotically in time, by using continuous-in-time coarse-mesh nodal-point observational measurements of the velocity field of this reference solution (subsampling), as might be measured by an array of weather vane anemometers. Our calculations show that the required nodal observation density is remarkably less that what is suggested by the analytical study; and is in fact comparable to the {\it number of numerically determining Fourier modes}, which was reported in an earlier computational study by the authors. Thus, this method is computationally efficient and performs far better than the analytical estimates suggest.

description: The four pieces in this section are innovative collaborations at various levels, ranging from anthropologists collaborating with communities to collaborative presentations as a way to subvert hierarchies and Euro-centric modes of being with/in academia. These papers engage with the relationship between collaboration and commoning, some explicitly and others implicitly, as ways to shape knowledge production and practice for a much more egalitarian ethnographic engagement within and beyond the academy. In this Special Section of Volume 2 of Commoning Ethnography, we share four papers that engage with the changing nature of ethnographic collaboration on multiple levels.
Transformative making and narrative : a visual exploration of objects and place through the archive
Creators: name: Stubbs, Sarah
Publisher: name: University Of Tasmania
Year: 2023

description: This practice-based research project focuses on memory, materiality and place as told through the archive, connecting with past lives and practices to contemplate and speak to our construction of self and place in the present. It has grown out of a body of work produced between 2016-2021 with a consistent focus on how the archive can be interpreted, reframed and contextualised poetically through the jewellery/art object to make sense of my own experiences of loss and displacement.The previously exhibited work is in response to three distinct collections: the Markree collection held at the Tasmanian Museum and Art Gallery, Hobart; a butterfly collection donated by Professor Peter Tyler to the Queen Victoria Museum and Art Gallery, Launceston; and my own private archive, consisting of a disparate group of objects/debris collected from a beach near my current home in Tasmania.The exegesis draws upon the theoretical writings of Gaston Bachelard, particularly The Poetics of Space and Jeff Malpas’, Place and Experience: A Philosophical Topography; and the literary writings of Virginia Woolf (To the Lighthouse); Orhan Pamuk (The Museum of Innocence); Kate Grenville (The Secret River) and Edmund de Waal (The Hare with Amber Eyes, Letters to Camondo) who collectively explore the interstices between fact and fiction.To contextualise my studio research, I have looked to key art installations in which there is an intersection between the autobiographical and the archive, focusing on Susan Hiller’s From the Freud Museum, Ilya Kabakov’s The Garbage Man (The Man who Never Threw anything Away) and Edmund de Waal’s Lettres à Camondo. While the strategies used by these artists differ, their work reflects a common concern for the archive, narrative and reimagining the past in ways that allow for new readings.All three of my above-mentioned exhibitions have presented guides and pathways to transformative making which comes from the study of narrative, objects, place and the archive which is central to my ongoing research. In my examination submission, this work is revisited and extended to further expand my research into how we use objects of the past to cast light on our own situation in the present.This research offers new ways of thinking about objects/jewellery through the crafting of an archive practice which engages memoir and making as an act to speak to, and of, the stories of others.

description: Reinforcement learning (RL) has shown great potential for solving complex tasks in a variety of domains. However, applying RL to safety-critical systems in the real-world is not easy as many algorithms are sample-inefficient and maximising the standard RL objective comes with no guarantees on worst-case performance. In this paper we propose approximate model-based shielding (AMBS), a principled look-ahead shielding algorithm for verifying the performance of learned RL policies w.r.t. a set of given safety constraints. Our algorithm differs from other shielding approaches in that it does not require prior knowledge of the safety-relevant dynamics of the system. We provide a strong theoretical justification for AMBS and demonstrate superior performance to other safety-aware approaches on a set of Atari games with state-dependent safety-labels.

description: In this paper we determine new upper bounds for the maximal density of translative packings of superballs in three dimensions (unit balls for the $l^p_3$-norm) and of Platonic and Archimedean solids having tetrahedral symmetry. Thereby, we improve Zong's recent upper bound for the maximal density of translative packings of regular tetrahedra from $0.3840\ldots$ to $0.3745\ldots$, getting closer to the best known lower bound of $0.3673\ldots$ We apply the linear programming bound of Cohn and Elkies which originally was designed for the classical problem of densest packings of round spheres. The proofs of our new upper bounds are computational and rigorous. Our main technical contribution is the use of invariant theory of pseudo-reflection groups in polynomial optimization.

description: Quantum vacuum fluctuations impose strict limits on precision displacement measurements, those of interferometric gravitational-wave detectors among them. Introducing squeezed states into an interferometer's readout port can improve the sensitivity of the instrument, leading to richer astrophysical observations. However, optomechanical interactions dictate that the vacuum's squeezed quadrature must rotate by 90 degrees around 50Hz. Here we use a 2-m-long, high-finesse optical resonator to produce frequency-dependent rotation around 1.2kHz. This demonstration of audio-band frequency-dependent squeezing uses technology and methods that are scalable to the required rotation frequency, heralding application of the technique in future gravitational-wave detectors.
