description: We demonstrate that electronic transport through single molecules or molecular ensembles, commonly based on gold (Au) electrodes, can be extended to superconducting electrodes by combining gold with molybdenum-rhenium (MoRe). This combination induces proximity-effect superconductivity in the gold to temperatures of at least 4.6 Kelvin and magnetic fields of 6 Tesla, improving on previously reported aluminum based superconducting nanojunctions. As a proof of concept, we show three-terminal superconductive transport measurements through an individual Fe$_4$ single-molecule magnet.

Concussion-Related Knowledge, Attitudes, Norms, and Expectations among Students at a Large Public University

description: Many factors influence student-athletes’ decision to disclose concussion symptoms. Understanding concussion-related culture that can affect disclosure behavior, specifically at the university level, is novel. This study investigated factors at a large, public university associated with concussion knowledge, attitudes, and norms among stakeholders and determined factors that influence these stakeholders’ expectations of student-athletes and fans regarding concussion.Faculty (n=22), staff (n=107), and students (n=130) completed an online questionnaire. We aimed to target all three groups. Due to low response across faculty and staff, we focused our primary results on students. There were significant associations between students’ concussion history, attitudes, and perceived norms and student-athlete expectations. These findings suggest general concussion notions were similar, but that some demographics affected expectations of student-athletes. These data may be used to inform concussion safety initiatives among students. Future studies should describe the factors which influence the university concussion culture, which could create safer environments for disclosure.

description: We study a system of $N\gg 1$ degrees of freedom coupled via a smooth homogeneous Gaussian vector field with both gradient and divergence-free components. In the absence of coupling, the system is exponentially relaxing to an equilibrium with rate $μ$. We show that, while increasing the ratio of the coupling strength to the relaxation rate, the system experiences an abrupt transition from a topologically trivial phase portrait with a single equilibrium into a topologically non-trivial regime characterised by an exponential number of equilibria, the vast majority of which are expected to be unstable. It is suggested that this picture provides a global view on the nature of the May-Wigner instability transition originally discovered by local linear stability analysis.

The Price Effects of Codeshare Products Under the United-Continental Airline Merger
Creators: name: Balasubramanian, Vinayak
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 2014

description: The existence of operational inefficiency in the U.S. airline industry, combined with rising costs and financial problems, has long prompted airlines to find ways to consolidate through mergers, and to cooperate through codeshare agreements and alliances. While the price and competition effects of mergers and codeshare agreements are well documented by existing research, there is comparatively little literature over a merger’s impact on the codeshare products between the merging firms, and on markets abundant in codeshare passengers. This paper seeks to fill this research gap by analyzing price data for 75 million passengers from four consecutive quarters before and four consecutive quarters after the United-Continental Airline merger. The results show a statistically significant price increase in former codeshare products in markets, and a statistically significant price decrease for codeshare products in highly concentrated markets. The data also shows a statistically significant price increase for non-concentrated markets that are abundant in codeshare passengers, and a statistically significant price decrease highly concentrated markets that are abundant in codeshare passengers. These findings indicate that antitrust authorities should pay more attention to markets that aren’t concentrated when making future merger decisions, particularly as the number of passengers taking advantage of codeshare tickets continues to increase.

Drawing from recent findings, I expect sexism as well as nudity to have negative effects on recipients' attitude towards the ad and the brand. Furthermore I expect a specific rank order (see hypotheses) and an interaction of nudity and sexism. Using different and more standardized stimuli (e.g., only one product category, holding product fit and brand familiarity constant) I want to conceptually replicate prior findings, whilst measuring attitude towards the ad and the brand more reliably.

Gamma-ray emitting supernova remnants as the origin of Galactic cosmic rays?

description: The origin of cosmic rays is one of the long-standing mysteries in physics and astrophysics. Simple arguments suggest that a scenario of supernova remnants (SNRs) in the Milky Way as the dominant sources for the cosmic ray population below the knee could work: in a generic calculation, it can be shown that these objects can provide the energy budget necessary to explain the observed flux of cosmic rays. However, this argument is based on the assumption that all sources behave in the same way, i.e.\ they all have the same energy budget, spectral behavior and maximum energy. In this paper, we investigate if a realistic population of SNRs is capable of producing the cosmic ray flux as it is observed below the knee. We use 21 SNRs that are well-studied from radio wavelengths up to gamma-ray energies. It could be shown previously (Mandelartz & Becker Tjus 2015) that the high-energy bump in the energy spectrum of these 21 sources can be dominated by hadronic emission. Here, gamma-rays are produced via $π^{0}-$decays from cosmic ray interactions in molecular clouds near the supernova remnant, which serves as the cosmic ray accelerator. The cosmic ray spectra show a large variety in their energy budget, spectral behavior and maximum energy. These sources are assumed to be representative for the total class of SNRs, where we assume that about 100 - 200 cosmic ray emitting SNRs should be present today. Finally, we use these source spectra to simulate the cosmic ray transport from individual SNRs in the Galaxy with the GALPROP code for cosmic ray propagation. We find that the cosmic ray budget can be matched well for a diffusion coefficient that is close to $D\propto E^{0.3}$. A stronger dependence on the energy, e.g. $E^{0.5}$, would lead to a spectrum at Earth that is too steep when compared to what is detected and the energy budget cannot be matched, in particular toward high energies.

Synthesis of elemental phosphorus and arsenic nanostructures
Creators: name: Winchester, Richard
Publisher: name: Imperial College London
Year: 2023

description: The experimental work described in this thesis concerns the synthesis of elemental nanorods consisting of phosphorus and arsenic. Growth of such nanostructures was achieved via the vapour-liquid-solid (VLS) mechanism in which a liquid metal catalyst nanoparticle acts as a medium for crystallisation from a vapour phase feedstock. The size of the metal droplet restricts lateral dimensions of the growing solid to the nanoscale. The aim of this research was to synthesise phosphorus and arsenic nanorods in a controllable manner and to characterise the resulting product. Methods are described for producing two distinct forms of phosphorus nanorods using a simple, ampoule-based technique. Relatively high aspect ratio phosphorus nanorods, which have a polycrystalline structure, were produced via VLS growth from a nanoscale bismuth catalyst formed in-situ on the silicon substrate surface. Faceted, single crystal phosphorus nanorods were produced without a catalyst via anisotropic crystallisation from the vapour. Control of the dimension of these products was obtained by modifying the synthesis temperature. The synthesis of 400-1700 nm diameter arsenic rods, via VLS growth from a lead catalyst, is described using a similar ampoule based technique. Investigations into the mechanism of formation of the active lead catalyst particles during ampoule synthesis are also presented. Experiments using pre-formed gold nanoparticles as a catalyst source show that arsenic rods with nanoscale dimensions can also be produced in good yield. The design, assembly and preliminary experiments with a custom built chemical vapour deposition (CVD) apparatus are also described. This apparatus represents a potentially more versatile approach to nanorod synthesis than the ampoule-based syntheses described elsewhere in this thesis. Preliminary experiments are presented which investigate the formation of phosphorus nanorods from bismuth and lead catalysts.

description: This paper presents a post hoc analysis of a deep learning-based full-disk solar flare prediction model. We used hourly full-disk line-of-sight magnetogram images and selected binary prediction mode to predict the occurrence of $\geq$M1.0-class flares within 24 hours. We leveraged custom data augmentation and sample weighting to counter the inherent class-imbalance problem and used true skill statistic and Heidke skill score as evaluation metrics. Recent advancements in gradient-based attention methods allow us to interpret models by sending gradient signals to assign the burden of the decision on the input features. We interpret our model using three post hoc attention methods: (i) Guided Gradient-weighted Class Activation Mapping, (ii) Deep Shapley Additive Explanations, and (iii) Integrated Gradients. Our analysis shows that full-disk predictions of solar flares align with characteristics related to the active regions. The key findings of this study are: (1) We demonstrate that our full disk model can tangibly locate and predict near-limb solar flares, which is a critical feature for operational flare forecasting, (2) Our candidate model achieves an average TSS=0.51$\pm$0.05 and HSS=0.38$\pm$0.08, and (3) Our evaluation suggests that these models can learn conspicuous features corresponding to active regions from full-disk magnetograms.

description: Large-scale force generation is essential for biological functions such as cell motility, embryonic development, and muscle contraction. In these processes, forces generated at the molecular level by motor proteins are transmitted by disordered fiber networks, resulting in large-scale active stresses. While these fiber networks are well characterized macroscopically, this stress generation by microscopic active units is not well understood. Here we theoretically study force transmission in these networks, and find that local active forces are rectified towards isotropic contraction and strongly amplified as fibers collectively buckle in the vicinity of the active units. This stress amplification is reinforced by the networks' disordered nature, but saturates for high densities of active units. Our predictions are quantitatively consistent with experiments on reconstituted tissues and actomyosin networks, and shed light on the role of the network microstructure in shaping active stresses in cells and tissue.

Health Promoting Employment Interventions for Unemployed Men in the United States:  A Scoping Review of the Literature
Creators: name: Smith, William H.
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 2015

description: While the economy and unemployment rates in the United States have improved since The Great
Recession, there are still millions of individuals searching for employment and untold others that
have removed themselves from the job search until opportunities return or new opportunities are
established. Men’s health disparities are tied to the social determinants of health, many of which
are inextricably linked with employment status. A scoping review of the existing quantitative
and qualitative literature was conducted to determine the breadth of research focusing on
employment interventions for unemployed men in the U.S. that have also included a measure of
health or health-related behavior. Studies meeting inclusion criteria were reviewed and entered
into tables for narrative analysis in accordance with a methodological framework proposed by
Arksey & O’Malley (2005). Results show that existing research has been restricted to pilot
studies addressing single health conditions or health behaviors and fail to address chronic health
and co-morbid conditions. Recommendations for future research are provided and limitations of
the current review are presented.

description: Ezetimibe (EZM) is a selective inhibitor of the sterol transporter Niemann-Pick C1-Like 1 in the small intestine used as an adjunctive therapy to lower cholesterol levels in cases of hyperlipidemia. The goal of this work was to summarize the main physical-chemical, pharmacological and pharmacokinetic characteristics of EZM, as well as to describe the main analytical methodologies for the quantification of the drug. Methods described in the United States Pharmacopeia for EZM raw material and tablets were also presented. The drug has a large number of process-related impurities and degradation products and needs strict quality control of its impurities. Specific chiral methods for the evaluation of its chiral impurities are also a need for EZM. The main advantages and disadvantages of the compiled analytical methods were presented, as well as the limits of detection and quantitation. The fastest and most efficient methods were highlighted. Most methods for analyzing EZM used C8 or C18 stationary phases in gradient mode with binary mobile phases containing acetonitrile and an acidic buffer solution with ultraviolet detection. For analysis of EZM in biological matrices, liquid chromatography-tandem mass spectrometry is generally employed using electron spray ionization in negative ionization mode using multiple reaction monitoring. Different methods in the literature evaluate a large number of impurities for EZM, however new stability-indicating high-performance liquid chromatography methods for the drug are still needed.

description: We present a new Machine Learning-based multivariate analysis method for the selection of time-correlated hits in the tagging system and devices used to detect particles in the final state at the bremsstrahlung-based tagged photon facilities. This method can be applied instead of the widely used sampling and subtraction of the time-uncorrelated background, in particular at experiments aiming for high precision, where the subtraction of the time-uncorrelated background leads to increased uncertainties. Moreover, the identification of events with Machine Learning algorithms allows to preserve the information about correlations of kinematic variables in the final state, which can be advantageous for further phenomenological analyses of the experimental results.

The structure of natural and experimentally deformed fault gouges
Creators: name: Page, A.
Publisher: name: Imperial College London
Year: 2023

description: This thesis reports the findings of multi-approach studies on major upper crustal fault gouge zones In the Internal Zone of the Betlc Cordilleras, southern Spain, and experimental work designed to attempt to simulate the features observed In natural fault zones. In the Betlc Zone’s Alpujarrlde Complex four phases of deformation were recognised. Major third phase brittle extenslonal faults cross-cut and thin second phase thrusts (Adra J Murtas) emplaced on more ductile shears zones. Gouge kinematic Indicators Indicate hanglngwall slip on the extenslonal faults to the northwest, equal to the emplacement direction of the thrusts. Cumulative slip on the gouge zones Is estimated to have been 4.6-5.5km. Intra-fault material In the extensional faults Is phy I I I te-der I ved gouge, comminuted largely by fracture-accommodated grain boundary sliding. Shearing of phyIloslIIcate dominated gouge develops mesostructures which have competing work hardening and work softening effects. Work hardening effects Include:(a) the antithetic rotation (continuous deformation) of shear planes (discontinuous deformation) particles and host rock slivers to generate fabrics antl-clockwise of the fault zone boundaries In dextral shear and, (b) the deactivation of shears. Work softening Is achieved by the propagation of new shear surfaces, shear linkage and shear reactivation. The phyllfte gouges show deform- utlon spreading rather than progressive localisation, which may arise from work hardening during gouge flow. Displacement shifting away from work hardened zones leads to the strain modIfloat Ion of mechanically softer protogouges and/or failure and slip at the gouge-host rock Interface. Structures on the Interface resemble those on recent selsmlcally active faults. Gouge particle comminution resulted In bulk and single mineral particle size distributions (psd's) which vary from coarse skews via scale Invariance to fine skews. Two dimensional fractal dimensions calculated for scale Invariant psd's (D=2.3+/-0.02 for all particles, and D=2.33+/-0.34 for quartz particles only: 2mm-0.001mm range) cannot derive by uniform or non-uniform length reduction models. For the scale Invariant distributions no upper limit was found, but lower limit deviation occurred at 20mlcrons. Effects Including enhanced cracking along grain boundaries, or from quartz-mica compliance differences under load, the dispersion of trail-derived particles, or Impingement suppression may explain lower limit deviation. Comparison of experimentally deformed quartz and quartz-kaolInlte synthetic gouges showed that the effect of adding kaolInlte Is to reduce the quartz comminution rate. Increase the range of s+rains across which transient particle size scale Invariance persists, and to enhance work hardening. In mica rich gouges, the hardening rate Increases as particle size decreases, and c°incldes with the maximum rate of mica comminution, the most homogenous deformation In shear 2°nes, and the maximum proportion of back-rotated particles.
Evaluating the Knowledge of Prehospital Care for Pediatric and Obstetric Patients Among Emergency Medical Services Personnel in North Carolina
Creators: name: Hunold, Thomas
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 2016

description: Emergency Medical Services (EMS) personnel rarely encounter pediatrics and obstetrics cases;
therefore, increased training in these areas is required to ensure that EMS personnel are prepared to
implement rarely used skills in emergency situations. A knowledge test was used to determine each
participating provider's level of knowledge over the areas of pediatrics and obstetrics. This paper aims
to describe the change in knowledge test scores over an approximately six-month time period as part of a
larger five year study that will utilize educational interventions to hopefully increase provider knowledge
of pediatric and obstetric care. Nine North Carolina EMS systems were recruited to participate in this
study. A knowledge test was developed, verified, and administered to the nine EMS systems over two
different time frames. The mean change in test score between the first and second test was calculated to
be -0.44 percent with a standard deviation of 7.06 percent. A t-test revealed that the change in knowledge
test score was not significantly different than zero. This indicates that the providers level of knowledge
with respect to pediatrics and obstetrics care did not change over time. Due to low participation rates,
the demographics of the providers who participated in both tests were compared to those who only
participated the first test. These analyses revealed that there were demographic differences, and that
there were differences between the test scores of those who participated in the first and second knowledge
tests. Due to these differences, caution should be used when generalizing the results back to the original
sample. However, because of the lack of association between provider demographics and change in
knowledge test score, the results were generalized back to the sample as a whole. Assuming that the
demographics of providers do not change over time, later changes in knowledge test score are likely the
result of educational interventions. There are several possible limitations of this study including: low
participation rates in the second knowledge test; the inability to consider all possible covariates, such
as participation in outside training courses or the frequency with which a provider works, and the fact
that communication was with the EMS System Administrators, not the providers themselves.

Suggesting a Reliable Method of Calculating Charge Collection Efficiency in Charge-transfer Measurement for Brush Discharges
Creators: name: Basu, Nirmalya
Publisher: name: Open Science Framework
Year: 2022

description: Induced charge errors lead to underestimation of transferred charge in brush discharges when the measurement is done using fast-response unshielded probes. The discrepancy observed between the values of charge-collection efficiency for different charge-transfer thresholds obtained theoretically by Walmsley [2] and those obtained experimentally by Chowdhury et al [3] necessitates figuring out ways to improve the mathematical model used by Walmsley. A close perusal of the said work by Walmsley [2] has pointed out an error therein– in the use of the equation reff = KD. I propose here a way to get rid of this error, and in doing so, I propose a method of calculating the charge-collection efficiency in charge-transfer measurement for brush discharges more reliable than that used by Walmsley [2].

description: Art seeks to understand, represent, and express life. By its nature, art is an act of collaboration, a result of ensemble. Theater as a facet of art, both creates community and is created by community. A community, or an ensemble in theatrical terms, is a group of individuals collaborating to create a piece larger than themselves. In the process of creating no less than the trees and the stars;, the creative team was encouraged to explore themselves within the piece, their relationship to the audience, and acknowledge the relationship of the audience to itself. The creation process of no less than the trees and the stars; was devised, its concept relying heavily on previously conducted interviews which were used as an inspiration for creative movement and relational exploration among the cast and creative team. Through the interdependence of ensemble and theater, the process of no less than the trees and the stars; sought to foster an environment in which individuals could express themselves and their opinions, be vulnerable with each other, belong to a team, and explore their mental and physical relation to space, time, and the people around them both on stage and throughout the rehearsal process.
Angier, The Last Frontier: Representation and Gentrification in the Alternative Food Movement

Year: 2017

description: The Angier Avenue Neighborhood Farm is located in predominantly Black East Durham, yet, Black residents that live in the neighborhood rarely participate in activities at the site. East Durham is also on the brink of major socioeconomic shifts; public and private developers are reinvesting in the neighborhood, planning the constructions of breweries and pizza shops that attract White middle class culture. This poses key problems for the sustainability of the Angier Avenue Neighborhood Farm and its ability to fulfill the present food and gardening needs of the community. The Angier Avenue Neighborhood Farm is a unique space to question certain patterns that exist in the alternative food movement. Why is there a lack of participation among Black people in the alternative food movement? What are the assumptions that explain why Black people are resistant to agricultural work? Why do urban farms and community gardens tend to be White spaces? What is the role of urban farms and community gardens in accelerating the process of gentrification? Based on 7 months of participant observation, interviews, and food systems research, I theorize the relationship between urban farming and gentrification. I argue that equitable and representative community food projects must actively incorporate the cultures and histories of Black East Durham residents if they are to truly function as a sustainable source of fresh, culturally relevant, affordable food.

description: Simile detection is a valuable task for many natural language processing (NLP)-based applications, particularly in the field of literature. However, existing research on simile detection often relies on corpora that are limited in size and do not adequately represent the full range of simile forms. To address this issue, we propose a simile data augmentation method based on \textbf{W}ord replacement And Sentence completion using the GPT-2 language model. Our iterative process called I-WAS, is designed to improve the quality of the augmented sentences. To better evaluate the performance of our method in real-world applications, we have compiled a corpus containing a more diverse set of simile forms for experimentation. Our experimental results demonstrate the effectiveness of our proposed data augmentation method for simile detection.

description: In this work we extend, review and jointly discuss earlier experiments conducted by us in hyperaged geological glasses, either in Dominican amber (20 million years old) or in Spanish amber from El Soplao (110 million years old). After characterization of their thermodynamic and elastic properties (using Differential Scanning Calorimetry around the glass-transition temperature, and measuring mass density and sound velocity), their specific heat was measured at low and very low temperatures. By directly comparing pristine amber samples (i.e. highly stabilized polymer glasses after aging for millions of years) to the same samples after being totally or partially rejuvenated, we have found that the two most prominent universal anomalous low-temperature properties of glasses, namely the tunnelling two-level systems and the so-called boson peak, persist essentially unchanged in both types of hyperaged geological glasses. Therefore, non-Debye low-energy excitations of glasses appear to be robust, intrinsic properties of non-crystalline solids which do not vanish by accessing to very deep states in the potential energy landscape.

description: As Arctic sea ice extent decreases with increasing greenhouse gases, there is a growing interest in whether there could be a bifurcation associated with its loss, and whether there is significant hysteresis associated with that bifurcation. A challenge in answering this question is that the bifurcation behavior of certain Arctic energy balance models have been shown to be sensitive to how ice-albedo feedback is parameterized. We analyze an Arctic energy balance model in the limit as a smoothing parameter associated with ice-albedo feedback tends to zero, which introduces a discontinuity boundary to the dynamical systems model. Our analysis provides a case study where we use the system in this limit to guide the investigation of bifurcation behavior of the original albedo-smoothed system. In this case study, we demonstrate that certain qualitative bifurcation behaviors of the albedo-smoothed system can have counterparts in the limit with no albedo smoothing. We use this perspective to systematically explore the parameter space of the model. For example, we uncover parameter sets for which the largest transition, with increasing greenhouse gases, is from a perennially ice-covered Arctic to a seasonally ice-free state, an unusual bifurcation scenario that persists even when albedo-smoothing is reintroduced. This analysis provides an alternative perspective on how parameters of the model affect bifurcation behavior. We expect our approach, which exploits the width of repelling sliding intervals for understanding the hysteresis loops, would carry over to other positive feedback systems with a similar natural piecewise-smooth limit, and when the feedback strength is likewise modulated with seasons or other periodic forcing.

description: Lyrics generation is a well-known application in natural language generation research, with several previous studies focusing on generating accurate lyrics using precise control such as keywords, rhymes, etc. However, lyrics imitation, which involves writing new lyrics by imitating the style and content of the source lyrics, remains a challenging task due to the lack of a parallel corpus. In this paper, we introduce \textbf{\textit{Sudowoodo}}, a Chinese lyrics imitation system that can generate new lyrics based on the text of source lyrics. To address the issue of lacking a parallel training corpus for lyrics imitation, we propose a novel framework to construct a parallel corpus based on a keyword-based lyrics model from source lyrics. Then the pairs \textit{(new lyrics, source lyrics)} are used to train the lyrics imitation model. During the inference process, we utilize a post-processing module to filter and rank the generated lyrics, selecting the highest-quality ones. We incorporated audio information and aligned the lyrics with the audio to form the songs as a bonus. The human evaluation results show that our framework can perform better lyric imitation. Meanwhile, the \textit{Sudowoodo} system and demo video of the system is available at \href{https://Sudowoodo.apps-hp.danlu.netease.com/}{Sudowoodo} and \href{https://youtu.be/u5BBT_j1L5M}{https://youtu.be/u5BBT\_j1L5M}.

description: We report the early discovery of the optical afterglow of gamma-ray burst (GRB) 140801A in the 137 deg$^2$ 3-$σ$ error-box of the Fermi Gamma-ray Burst Monitor (GBM). MASTER is the only observatory that automatically react to all Fermi alerts. GRB 140801A is one of the few GRBs whose optical counterpart was discovered solely from its GBM localization. The optical afterglow of GRB 140801A was found by MASTER Global Robotic Net 53 sec after receiving the alert, making it the fastest optical detection of a GRB from a GBM error-box. Spectroscopy obtained with the 10.4-m Gran Telescopio Canarias and the 6-m BTA of SAO RAS reveals a redshift of $z=1.32$. We performed optical and near-infrared photometry of GRB 140801A using different telescopes with apertures ranging from 0.4-m to 10.4-m. GRB 140801A is a typical burst in many ways. The rest-frame bolometric isotropic energy release and peak energy of the burst is $E_\mathrm{iso} = 5.54_{-0.24}^{+0.26} \times 10^{52}$ erg and $E_\mathrm{p, rest}\simeq280$ keV, respectively, which is consistent with the Amati relation. The absence of a jet break in the optical light curve provides a lower limit on the half-opening angle of the jet $θ=6.1$ deg. The observed $E_\mathrm{peak}$ is consistent with the limit derived from the Ghirlanda relation. The joint Fermi GBM and Konus-Wind analysis shows that GRB 140801A could belong to the class of intermediate duration. The rapid detection of the optical counterpart of GRB 140801A is especially important regarding the upcoming experiments with large coordinate error-box areas.

Home is for the Making: Rethinking Home in a Participatory Action Based Workshop
Creators: name: Coury, Katherine
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 2017

description: Home for those who live outside the normative notion of a private space may have
complicated realities, may be endowed with a traumatic experience such as loss or abuse. It may
be fragmented by displacement or the incorporation of the public. This paper argues that for
advocates trying to close gaps in health and wellness for marginalized groups like people living
with mental illness, it is essential to consider critiques of the very idea of home which policy
extends.
However, I also argue that this critique is incomplete if it stops with the experience of
exclusion. Part of this exclusion is inherent in the dynamics which license researchers and
providers to generate or synthesize knowledge and demote the patient’s and researched’s
participation in the process. A more complete critique must offer access to knowledge formation
surrounding the understanding of home to people living with mental illness. It will both collect
and amplify their voices surrounding the lived experience of home but also facilitate a self
reflexive group process of reimagining “home” as a flexible space that embraces differences
which may undermine dominant constructions of this space.

description: The coupling of electrons to spin excitations and the generation of magnons is essential for spin mixing in the ultrafast magnetization dynamics of 3d ferromagnets. Although magnon energies are generally much larger than phonon energies, until now their electronic band renormalization effect in 3d ferromagnets suggests a significantly weaker quasiparticle interaction. Using spin- and angle-resolved photoemission, we show an extraordinarily strong renormalization leading to two-branch splitting of an iron surface resonance at ∼200 meV. Its strong magnetic linear dichroism unveils the magnetic nature and momentum dependence of the energy renormalization. By determining the frequency- and momentum-dependent self-energy due to generic electron–boson interaction to compute the resultant electron spectral function, we suggest that the surface-state splitting can be described by strong coupling to an optical spin wave in an iron thin film.

description: Shor's factoring algorithm is one of the most anticipated applications of quantum computing. However, the limited capabilities of today's quantum computers only permit a study of Shor's algorithm for very small numbers. Here we show how large GPU-based supercomputers can be used to assess the performance of Shor's algorithm for numbers that are out of reach for current and near-term quantum hardware. First, we study Shor's original factoring algorithm. While theoretical bounds suggest success probabilities of only 3-4 %, we find average success probabilities above 50 %, due to a high frequency of "lucky" cases, defined as successful factorizations despite unmet sufficient conditions. Second, we investigate a powerful post-processing procedure, by which the success probability can be brought arbitrarily close to one, with only a single run of Shor's quantum algorithm. Finally, we study the effectiveness of this post-processing procedure in the presence of typical errors in quantum processing hardware. We find that the quantum factoring algorithm exhibits a particular form of universality and resilience against the different types of errors. The largest semiprime that we have factored by executing Shor's algorithm on a GPU-based supercomputer, without exploiting prior knowledge of the solution, is 549755813701 = 712321 * 771781. We put forward the challenge of factoring, without oversimplification, a non-trivial semiprime larger than this number on any quantum computing device.
