Voguing: Examples of performance through art, gender and identity
Creators: name: Birardi Mazzone, Gabriella
name: Peressini, Gioele
Publisher: name: Mantichora. Italian Journal of Performance Studies
Year: 2020

description: This paper is the result of a thirty hour seminar on Performance Studies, taught by Dr. Carmela Cutugno at the University of Bologna, as part of a Master course in Theories and Cultures of Representation held by Professor Marco De Marinis. The idea for the chosen topic, as well as part of the readings were suggested during the seminar by Dr. Cutugno, who assisted us for the entire process of thinking and writing about this issues. The seminar was conceived and realized as a performance studies analysis workshop and the final paper was presented, performed and danced as the result of the course. This essay is a synopsis of that work, focused on Voguing, firstly as artistic and cultural performance, and then upon the differences between the U.S.A. context and the Italian context, which were both supported by the dichotomy between artistic performance and “gender performativity”. The first part of this essay starts from this point to analyze the process of transformation, and differentiation of the voguing culture, paying particular attention to the Italian performative scene. In the second part a further analysis is carried out, taking into account all the topics connected to the ideas of identity and gender.

High-Energy Neutrino Signatures of Newborn Pulsars In the Local Universe
Creators: name: Fang, Ke
Publisher: name: arXiv
Year: 2014
Subjects: subject: High Energy Astrophysical Phenomena (astro-ph.HE)
subject: FOS: Physical sciences

description: Charged particles can be accelerated to higher than PeV energies in the electro-magnetic wind of a fast-spinning newborn pulsar to produce high-energy neutrinos, through hadronuclear interactions in the supernova remnant. Here we explore the detectability and observational signatures of these high-energy neutrinos. We show that their spectral index varies approximately from 1.5 to 2, depending on the relevant pulsar properties and observation time. We also apply the scenario to existing young pulsars in the local universe and find the corresponding neutrino flux well below current detection limits. Finally, we estimate the birth rate of fast-spinning pulsars in the local Universe that can be observed by the IceCube observatory to be 0.07 per year, with an upper limit of 0.29 per year.

Libraries--Special collections--Zines

description: Institutional collection of zines is a relatively new endeavor, with the ramifications of doing so still being considered. This analysis of the zine collection at the UNC-Chapel Hill Sloane Art Library will look at the composition of the roughly 350-item collection through a number of lenses. First, what are the subjects and themes of zines in the collection, and what are the thematic strengths of the collection? Second, with what frequency are the zines used, and what are the commonalities across those most frequently used? Third, what are the ethical ramifications of institutions collecting zines in terms of whether these collections promote or restrict access?
Da Laas Gaal al John Lennon Wall: Homo sapiens tra tecnologie e nuove dimensioni rituali
Creators: name: Nucera, Sebastiano
Publisher: name: Mantichora. Italian Journal of Performance Studies
Year: 2020

description: The aim of this essay is to demonstrate how, starting from a continuous reconfiguration of ecological patterns, Homo sapiens has performed a transaction of the architectures that allow him to relate to his own conspecifics and to constantly changing contexts. This transaction, which has been realised in particular by the refinement of his artefacts and by a new understanding of these, creates, in fact, new ontological levels that are destined, in turn, to following transformations. More precisely, the interaction between individual and environment has produced, throughout the evolutionary history of Homo sapiens, a “creative bond” that has remodelled the very concept of living in (and reacting in) the world. The creative evolution that accompanies the history of the modern man is one of the most powerful and versatile types of “grammar”, which paves the way for new task-scapes, redefines boundaries and ways of interaction between “body” and “environment” but, above all, makes the creation of increasingly more user-friendly communicative niches possible today, creating symbolic flows that are increasingly less infused in biological matrices. In other words, the interactional loop between individual and environment creates the cognitive equivalent (Clarck, 2004) of Dawkins’ Extended Phenotype (1982) that, along with a spatial constraint of the physical world, provokes an expansion in the relationship among agents, culture and social networks at the same time.

description: Let the compact torus $T^{n-1}$ act on a smooth compact manifold $X^{2n}$ effectively with nonempty finite set of fixed points. We pose the question: what can be said about the orbit space $X^{2n}/T^{n-1}$ if the action is cohomologically equivariantly formal (which essentially means that $H^{odd}(X^{2n};\mathbb{Z})=0$). It happens that homology of the orbit space can be arbitrary in degrees $3$ and higher. For any finite simplicial complex $L$ we construct an equivariantly formal manifold $X^{2n}$ such that $X^{2n}/T^{n-1}$ is homotopy equivalent to $Σ^3L$. The constructed manifold $X^{2n}$ is the total space of the projective line bundle over the permutohedral variety hence the action on $X^{2n}$ is Hamiltonian and cohomologically equivariantly formal. We introduce the notion of the action in $j$-general position and prove that, for any simplicial complex $M$, there exists an equivariantly formal action of complexity one in $j$-general position such that its orbit space is homotopy equivalent to $Σ^{j+2}M$.

description: Canonical quantization of spherically symmetric space-times is carried out, using real-valued densitized triads and extrinsic curvature components, with specific factor ordering choices ensuring in an anomaly free quantum constraint algebra. Comparison with previous work [1] reveals that the resulting physical Hilbert space has the same form, although the basic canonical variables are different in the two approaches. As an extension, holonomy modifications from Loop Quantum Gravity are shown to deform the Dirac space-time algebra, while going beyond `effective' calculations.

description: One of the major resource requirements of computers - ranging from biological cells to human brains to high-performance (engineered) computers - is the energy used to run them. Those costs of performing a computation have long been a focus of research in physics, going back to the early work of Landauer. One of the most prominent aspects of computers is that they are inherently nonequilibrium systems. However, the early research was done when nonequilibrium statistical physics was in its infancy, which meant the work was formulated in terms of equilibrium statistical physics. Since then there have been major breakthroughs in nonequilibrium statistical physics, which are allowing us to investigate the myriad aspects of the relationship between statistical physics and computation, extending well beyond the issue of how much work is required to erase a bit. In this paper I review some of this recent work on the `stochastic thermodynamics of computation'. After reviewing the salient parts of information theory, computer science theory, and stochastic thermodynamics, I summarize what has been learned about the entropic costs of performing a broad range of computations, extending from bit erasure to loop-free circuits to logically reversible circuits to information ratchets to Turing machines. These results reveal new, challenging engineering problems for how to design computers to have minimal thermodynamic costs. They also allow us to start to combine computer science theory and stochastic thermodynamics at a foundational level, thereby expanding both.

description: This is the transcript of a video-interview I realized with Rebecca Schneider, Professor of Theatre and Performance Studies at Brown University, in May 2012. In this conversation Professor Schneider talks about her work as a Performance Studies scholar and the specific focus of her research interests. By thinking critically about certain aspects of this discipline, above all in relation to Theatre Studies, she underlines the dialogue between performativity and theatricality, as well as the importance of a certain kind of historiography in Performance Studies research methodology. Moving from the ontology of Performance Studies to the ontology of performance, she finally focuses on the idea that performance does not disappear, as she explains in her most recent book, “Performing Remains”.

Anderson localization and the quantum phase diagram of three dimensional disordered Dirac semimetals

description: We study the quantum phase diagram of a three dimensional non-interacting Dirac semimetal in the presence of either quenched axial or scalar potential disorder, by calculating the average and the typical density of states as well as the inverse participation ratio using numerically exact methods. We show that as a function of the disorder strength a half-filled (i.e. undoped) Dirac semimetal displays three distinct ground states, namely an incompressible semimetal, a compressible diffusive metal, and a localized Anderson insulator, in stark contrast to a conventional dirty metal that only supports the latter two phases. We establish the existence of two distinct quantum critical points, which respectively govern the semimetal-metal and the metal-insulator quantum phase transitions and also reveal their underlying multifractal nature. Away from half-filling the (doped) system behaves as a diffusive metal that can undergo Anderson localization only, which is shown by determining the mobility edge and the phase diagram in terms of energy and disorder.

Subjects: subject: 111504 Pharmaceutical Sciences
subject: FOS: Clinical medicine

description: Drug candidates with low aqueous solubility and low permeability are increasingly common in modern drug discovery programs. These properties, however, are problematic for the oral administration of these drugs as the intestinal absorption and uptake in blood will be hampered. Dissolving these drugs in lipid-based formulations (LBFs) can overcome the solubility barrier and polymers may be added to increase drug absorption. Little is known about the driving forces of absorption from these LBFs in the presence of polymers. This thesis describes the development of in vitro, in vivo, and computational models to understand this process.
Archives and Outreach Methods: How Far Have We Really Come; A Comparative Case Study.

description: Outreach is one of the main ways archives encourage access to their communities, for what is the point of keeping that history if no one can use it or benefit from it. Archival outreach deserves more scholarly attention because while many have described its current weaknesses, the field is still seeking solutions. Some institutions try to be innovative in their outreach, going above and beyond to make themselves available to the public. Unfortunately, these types of institutions seem to be the exception rather than the norm. This begs the question, why is there such disparity between institutions when we know that access and outreach are core functions of archives? Looking at three US southern universities, this comparative case study attempts to find the differences between these institutions and their methods of outreach.
Multi-particle systems in $κ$-Poincaré inspired by 2+1D gravity

description: Inspired by a Chern-Simons description of 2+1D gravity coupled to point particles we propose a new Lagrangian of a multiparticle system living in $κ$-Minkowski/$κ$-Poincaré spacetime. We derive the dynamics of interacting particles with $κ$-momentum space, alternative to the one proposed in the "principle of relative locality" literature. The model that we obtain takes into account of the nonlocal topological interactions between the particles, so that the effective multi-particle action is not a sum of their free actions. In this construction the locality of particle processes is naturally implemented, even for distant observers. In particular a particle process is characterized by a local deformed energy-momentum conservation law. The spacetime transformations are generated by total charges/generators for the composite particle system, and leave unaffected the locality of individual particle processes.

Analyzing the real-world impacts of the use of Community Gardens and Urban Agriculture

Community gardens

description: Climate change-related issues of flooding, global warming, and growing food insecurity are exacerbating the current Food Desert crisis and obesity epidemic in the United States. According to data from the CDC and USDA, 58 of the 258 Texas Counties are considered Food Deserts. Many Texans do not have a vehicle or live within a mile of a supermarket, leaving them without access to healthy, affordable food. This creates an endless cycle of obesity, preventable illness, nutritional deficiencies, and food insecurity. Society has begun to adapt to these circumstances by using Urban Agriculture, Community Gardens, and Schoolyard Gardens to increase food security in cities and for lower-income populations. This is also helpful in providing nutrition education for children and adults who otherwise do not have access. The use of these gardens is relatively new on the timeline of human existence, and little research exists to identify just how effective these gardens have been in aiding humanity. Currently, there is little information about health benefits, social benefits, and environmental benefits from these green spaces as a whole. This paper will serve as a comprehensive report on the real-world impacts of these green spaces. The research will outline how effective these projects are in increasing the supply of nutrient-rich, minimally processed foods in low-income areas and looking at heat maps and food desert maps. The report will also examine whether or not these gardens are effective in reducing obesity rates and creating a sense of community. Are Community Gardens living up to what they promise?

description: The emerging paradigm of abundant-data computing requires real-time analytics on enormous quantities of data collected by a mushrooming network of sensors. Todays computing technology, however, cannot scale to satisfy such big data applications with the required throughput and energy efficiency. The next technology frontier will be monolithically integrated chips with three dimensionally interleaved memory and logic for unprecedented data bandwidth with reduced energy consumption. In this work, we exploit the atomically thin nature of the graphene edge to assemble a resistive memory stacked in a vertical three dimensional structure. We report some of the lowest power and energy consumption among the emerging non-volatile memories due to an extremely thin electrode with unique properties, low programming voltages, and low current. Circuit analysis of the architecture using experimentally measured device properties show higher storage potential for graphene devices compared that of metal based devices.

The PAs were produced by the Facilitators and Monitors of the 20 SHERPA MAPs established at the beginning of the project. This first batch of PAs is accessible on a dedicated page on the SHERPA website. In September 2023, this second batch of 20 PAs was produced based on the experience and knowledge gathered during the second phase of running 41 SHERPA MAPs. The PAs were produced by the Facilitators and Monitors of the 20 SHERPA MAPs that were established during the second phase of SHERPA in addition to the 21 MAPs established in the first phase. The Facilitators and Monitors have outlined their learnings and recommendations on the process of setting up the MAPs, engaging actors and running activities in a sciencesociety-policy interface

Readers' advisory services

description: Readers’ advisory services have long been a foundational part of public libraries. This paper seeks to investigate how libraries offer these services online and whether or not their prevalence correlates with various other library characteristics. The study employs manifest content analysis and statistics to illuminate the associations between online readers’ advisory services being offered through public library websites and additional library data scraped from national surveys. Because the scope of the study is limited to North Carolina systems, its findings are not exhaustive enough to be applied to public library trends as a whole. However, the data explored holds the significance needed to begin a wider conversation about the evolving relationship between public libraries and online readers’ advisory.

Lineage

description: An important distinction of the Black American lineage is that it consists of those descended from people enslaved under US chattel slavery. This lineage is distinct from other African diasporic peoples whose histories do not include enslavement within the United States. Black Americans have a distinct culture, experience, and worldview that is unique to them. They experience racism and white supremacy that is linked to government policies from slavery to the modern day. Several presidential administrations have directly addressed the plight of Black Americans through published literature. However, the policies put forth in these documents do not delineate the Black American lineage from other disadvantaged groups, ultimately limiting the efficiency of their stated goals to positively impact Black Americans.
Ladder operators for solvable potentials connected with exceptional orthogonal polynomials

subject: FOS: Physical sciences

description: Exceptional orthogonal polynomials constitute the main part of the bound-state wavefunctions of some solvable quantum potentials, which are rational extensions of well-known shape-invariant ones. The former potentials are most easily built from the latter by using higher-order supersymmetric quantum mechanics (SUSYQM) or Darboux method. They may in general belong to three different types (or a mixture of them): types I and II, which are strictly isospectral, and type III, for which k extra bound states are created below the starting potential spectrum. A well-known SUSYQM method enables one to construct ladder operators for the extended potentials by combining the supercharges with the ladder operators of the starting potential. The resulting ladder operators close a polynomial Heisenberg algebra (PHA) with the corresponding Hamiltonian. In the special case of type III extended potentials, for this PHA the k extra bound states form k singlets isolated from the higher excited states. Some alternative constructions of ladder operators are reviewed. Among them, there is one that combines the state-adding and state-deleting approaches to type III extended potentials (or so-called Darboux-Crum and Krein-Adler transformations) and mixes the k extra bound states with the higher excited states. This novel approach can be used for building integrals of motion for two-dimensional superintegrable systems constructed from rationally-extended potentials.

description: We demonstrate the role of proximity effect in the thermal hysteresis of superconducting constrictions. From the analysis of successive thermal instabilities in the transport characteristics of micron-size superconducting quantum interference devices with a well-controlled geometry, we obtain a complete picture of the different thermal regimes. These determine whether the junctions are hysteretic or not. Below the superconductor critical temperature, the critical current switches from a classical weak-link behavior to one driven by the proximity effect. The associated small amplitude of the critical current makes it robust with respect to the heat generation by phase-slips, leading to a non-hysteretic behavior.

description: After years of development, FPGAs are finally making an appearance on multi-tenant cloud servers. Heterogeneous FPGA-CPU microarchitectures require reassessment of common assumptions about isolation and security boundaries, as they introduce new attack vectors and vulnerabilities. In this work, we analyze the memory and cache subsystem and study Rowhammer and cache attacks enabled by two proposed heterogeneous FPGA-CPU platforms from Intel: the Arria 10 GX with an integrated FPGA-CPU platform, and the Arria 10 GX PAC expansion card which connects the FPGA to the CPU via the PCIe interface. We demonstrate JackHammer, a novel, efficient, and stealthy Rowhammer from the FPGA to the host’s main memory. Our results indicate that a malicious FPGA can perform twice as fast as a typical Rowhammer from the CPU on the same system and causes around four times as many bit flips as the CPU attack. We demonstrate the efficacy of JackHammer from the FPGA through a realistic fault attack on the WolfSSL RSA signing implementation that reliably causes a fault after an average of fifty-eight RSA signatures, 25% faster than a CPU Rowhammer. In some scenarios our JackHammer attack produces faulty signatures more than three times more often and almost three times faster than a conventional CPU Rowhammer. Finally, we systematically analyze new cache attacks in these environments following demonstration of a cache covert channel across FPGA and CPU.

description: The forces applied to the prosthesis during human activity produce dynamic stresses varying in time and
may causing stress shielding in prosthesis-bone system. Therefore, it is important to reduce stress
shielding effect. This study aimed to investigates, using finite element analysis, how a PEEK and carbon/
PEEK composite coating materials on a titanium alloy hip implant stem could reduce stress shielding
effect corresponding to different human activities: standing up, normal walking and climbing stairs
under dynamic loadings to find out which of all these models have a better performance. A 3D finite
element model of femur, hip implants, coating layers with composite (carbon/PEEK) and polymeric
(PEEK) coating materials were constructed for finite element analysis. A time-dependent cycling load
was applied on the prosthesis head. The maximum increase in load transfer to the bone was 207% for
the prosthesis coated with carbon/PEEK configuration I (fibers orientated with 0, +45, -45, and 90
degrees) in average compared to uncoated one. Numerical result showed that the carbon/PEEK
composite material (configuration I) seems to be a good solution to distribute the applied load and
transfer it to the bone, thus to reduce stress shielding problems and to prolong lifetime of the prosthesisbone system. It will prevent aseptic loosening and enhance the stability of the system

This study examines the innerworkings of five rare archival repositories as they consider and understand this concept of context and the impact it has within each organization. All archives hold unique records, but this study addresses those with more highly specialized materials. Comparisons are made amongst the interviewed repositories, as well as with archival and information science practices overall. The results display a range of impact in how context influences the archivists and repositories overall, but the rare nature of the records is a driving force in curating and interacting with the repositories’ internal environment and external community.

description: Following a new quantum cosmological model proposed by Dvali and Gomez, we quantitatively investigate possible modifications to the Hubble parameter and following corrections to the cosmic microwave background spectrum. In this model, scalar and tensor perturbations are generated by the quantum depletion of the background inflaton and graviton condensate respectively. We show how the inflaton mass affects the power spectra and the tensor-to-scalar ratio. Masses approaching the Planck scale would lead to strong deviations, while standard spectra are recovered for an inflaton mass much smaller than the Planck mass.

description: The Common Agricultural Policy (CAP) is the first policy framework intervening in rural areas, pursuing various objectives and related specific objectives accordingly (Pagnon et al., 2023). A more strategic approach to the implementation of CAP specific objectives is unfolded into pluriannual national plans, which are overseeing by a performance framework bound by target value and indicators to be reach (EC, 2021). When designing their CAP strategic plans (CSPs), Member States have been formelly asked by the European Commission (EC) to observe extra requirements regarding ambitions and strategies related to the EU Green Deal (EUGD) objectives and targets, i.e. through the Farm-to-Fork strategy and the biodiversity strategy (COM, 2020). In parallel to the process of CSPs design undertaken by Member States, a new strategy for rural areas has been issued by the EC: 'A long-term vision for rural areas (LTVRA): towards stronger, connected, prosperous and resilient rural areas by 2040' (EC, 2021).

description: The purpose of this study is twofold: To recover and add to existing research concerning books printed, published, and sold by widows performed by former Wilson Library catalogers and to uncover potential reasons why this research was eliminated or effaced in the OPAC system. Through enumerative bibliography and comparative analysis this master’s paper seeks to document and demonstrate the ways in which prioritization of information effects scholarship related to Print Culture, Labor History, Women’s Studies, and Book History. In addition to advocating for the critical examination of contemporary cataloging practices with regards to women’s labor, this bibliography will seek to make plain the kinship of Library History and Book History.
A stochastic evolutionary model for capturing human dynamics

description: The recent interest in human dynamics has led researchers to investigate the stochastic processes that explain human behaviour in various contexts. Here we propose a generative model to capture the dynamics of survival analysis, traditionally employed in clinical trials and reliability analysis in engineering. We derive a general solution for the model in the form of a product, and then a continuous approximation to the solution via the renewal equation describing age-structured population dynamics. This enables us to model a wide range of survival distributions, according to the choice of the mortality distribution. We provide empirical evidence for the validity of the model from a longitudinal data set of popular search engine queries over 114 months, showing that the survival function of these queries is closely matched by the solution for our model with power-law mortality.

description: For a prescribed porosity, the coupled magma/mantle flow equations can be formulated as a two-field system of equations with velocity and pressure as unknowns. Previous work has shown that while optimal preconditioners for the two-field formulation can be obtained, the construction of preconditioners that are uniform with respect to model parameters is difficult. This limits the applicability of two-field preconditioners in certain regimes of practical interest. We address this issue by reformulating the governing equations as a three-field problem, which removes a term that was problematic in the two-field formulation in favour of an additional equation for a pressure-like field. For the three-field problem, we develop and analyse new preconditioners and we show numerically that they are optimal in terms of problem size and less sensitive to model parameters, compared to the two-field preconditioner. This extends the applicability of optimal preconditioners for coupled mantle/magma dynamics into parameter regimes of physical interest.

Data journals: Where data sharing policy meets practice
Creators: name: Dilles, Zoe
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 2023

description: Data journals incorporate elements of traditional scholarly communications practices—reviewing for quality and rigor through editorial and peer-review—and the data sharing / open data movement—prioritizing broad dissemination through repositories, sometimes with curation or technical checks. Their goals for dataset review and sharing are recorded in journal-based data policies and operationalized through workflows. In this qualitative, small cohort semi-structured interview study of eight different journals that review and publish research data, we explored (1) journal data policy requirements, (2) data review standards, and (3) implementation of standardized data evaluation workflows. Differences among the journals can be understood by considering editors' approaches to balancing the interests of varied stakeholders. Assessing data quality for reusability is primarily conditional on fitness for use which points to an important distinction between disciplinary and discipline-agnostic data journals.

description: This proposal addresses the social determinants of health for Lesbian, Gay, Bisexual, Transgender, and Queer (LGBTQ+) adults in Durham County, highlighting the importance of social support for their well-being. LGBTQ+ individuals experience higher rates of loneliness, leading to health disparities. An intergenerational community program is proposed to address these challenges by fostering relationships between younger and older LGBTQ+ adults through art and cultural events. This program will reduce isolation, promote social connectedness, and improve emotional and physical health. Collaboration with the Durham County Public Health Department, LGBTQ Center of Durham, and other LGBTQ+ affirming organizations will allow for support and resources. Focus groups, status reports, and evaluation surveys will ensure community engagement and program effectiveness. Establishing a dedicated task force addressing loneliness will demonstrate Durham County's commitment to LGBTQ+ well-being. The initiative seeks to enhance social connectedness and health outcomes for LGBTQ+ adults through community engagement and data-driven improvements.
