description: We present a complete set of multiparticle correlation observables for ultrarelativistic heavy-ion collisions. These include moments of the distribution of the anisotropic flow in a single harmonic, and also mixed moments, which contain the information on correlations between event planes of different harmonics. We explain how all these moments can be measured using just two symmetric subevents separated by a rapidity gap. This presents a multi-pronged probe of the physics of flow fluctuations. For instance, it allows to test the hypothesis that event-plane correlations are generated by non-linear hydrodynamic response. We illustrate the method with simulations of events in A MultiPhase Transport (AMPT) model.

description: Compliance with regulatory directives has been at the forefront of concern regarding federal contract spending. Private firms, federal agencies, and scholars allocate tremendous amounts of time, effort, and resources to produce efficient methods and strategies to combat the proliferation of compliance infractions, that often result in sanctions. The purpose of this research is to assess the performance of companies with C&E programs and those without C&E programs. A literature review of historical and current unclassified government data was collected from several public U. S. Government systems to determine the statistical relationship between Compliance and Ethic programs and non-Compliance and Ethic program penalties. The population under study consisted of 49 DoD contractors totaling an aggregate value of $212.4 billion obligated contracting dollars. A total of 364 fraud cases and $6.2 billion in fines were identified in this study. The study concluded that companies with Compliance and Ethics had a statistically significantly higher penalties and a penalty ratio than those without Compliance and Ethics. However, there were no differences in dollars obligated based on Compliance and Ethics programs. The implication of Compliance and Ethics programs decreasing fraud penalties in DoD contracting supports the need for effective regulatory oversight within organizations and future research on the compliance and ethics programs of firms contracting with the DoD. 
How to Make Accessible Marketing Content: A Comprehensive Guide Intended for Digital Marketers, Solopreneurs, and Professional Communicators That Centers the Experiences of Disabled Consumers

description: "Digital accessibility enables a wide range of users, including disabled users, to navigate, contribute to and engage with digital content. Without digital accessibility, a large portion of the population is unable to fully access the free marketplace of ideas we call the internet— specifically, disabled individuals who rely on the use of assistive technology (AT), such as a screen-readers, magnification software, and closed captions. If digital content is not properly coded to interact with assistive technology, those who rely on it become left out. 

 I set out to complete my thesis project on accessibility in communications and marketing because as a non-disabled professional communicator and creative leader, I knew it was an area where my team and I had only scratched the surface of all there is to learn, to the disadvantage of our disabled audience members.  My solution for this was to seek out the experiences of disabled consumers directly using survey data. With this data, I have created a guide in which those experiences, pain points, and insights can inform the creation of future communications and marketing content.  

I have explored the literature, frameworks, and guidance from disability activists, lawyers and authors, learning all that I can about the barriers that exist for disabled consumers, and the impact accessibility can have. At the heart of my research is a survey I designed for disabled consumers to complete, inviting them to tell me about their experiences with digital marketing and brands. This thesis project is a distillation of what I’ve learned from this research. "

description: Лук шалот (Allium ascalonicum L.) возделывается во многих странах мира. В России распространен повсеместно, но не имеет промышленного значения, выращивается на личных подсобных участках. Преобладает вегетативное размножение шалота. Для ускорения производства посадочного материала и повышения урожайности культуры необходимы новые сорта с комплексом хозяйственно-ценных признаков и разработка сортовой технологии возделывания лука-шалота. Лаборатории северного овощеводства ВНИИО - филиал ФГБНУ ФНЦО в Кировской области провели в 2018-2020 гг. исследования по разработке элементов технологии возделывания сорта шалота Братский. Установлено, что период вегетации не зависит от размера посадочных луковиц и схем их размещения. Гнездность, число листьев на растении, площадь листовой поверхности возрастали с увеличением фракционного состава и расстоянием между луковицами в ряду. Наибольшая урожайность в опытах достигнута при использовании в качестве семенного материала луковиц среднего размера в четырехстрочной схеме посадки 32+32+76 х15см - 39,3 т/га, что на 11,9 т/га больше контроля. Крупные луковицы массой 44,9 - 49,1 г формировались в двухстрочных схемах при посадке мелкой фракции луковиц диаметром 10-20 мм.

Subjects: Interactive multimedia

description: This proposal examines the historical role of Western influence starting with Spanish, British and American colonization and its role in Nicaragua throughout the years of establishing itself as a country. This proposal goes through Nicaraguan history leading up to the Sandinista Revolution which forced my mother and aunt to leave the country and eventually make their way to the United States.   

This project focuses on these examples of forced migration that inevitably led to the story of my birth in the United States. Through the storytelling of those who experienced the journey, a mixture of archival materials and animation, a film will tell the story of the perils of making it to a new country. The style of the film will be journalistic with narration by me, guiding the viewer along through the history and journey. It will be a journey of self-discovery of my own understanding of the historical significance of the time period that led up to the eventual migration of my family. As well as learning the differences between my upbringing and theirs and why their views about the revolution have differed from mine in the past.

description: The presence of two light higgsinos nearly degenerate in mass is one of the important characteristics of suspersymmetric models meeting the naturalness criteria. Probing such higgsinos at the LHC is very challenging, in particular when the mass-splitting between them is less than 5 GeV. In this study, we analyze such a degenerate higgsino scenario by exploiting the high collinearity between the two muons which originate from the decay of the heavier higgsino into the lighter one and which are accompanied by a high-$p_T$ QCD jet. Using our method, we can achieve a statistical significance $\sim 2.9\,σ$ as well as a $S/B \sim 17\%$ with an integrated luminosity of 3000 fb$^{-1}$ at the 14 TeV LHC, for the pair production of higgsinos with masses 124 GeV and 120 GeV. A good sensitivity can be achieved even for a smaller mass-splitting when the higgsinos are lighter.

description: This study explored the cryptocurrency's user adoption through the mental models of non-users. The research consisted of three parts: 1) a brief online questionnaire, 2) one-on-one interviews, 3) the creation of a deliverable in the form of a mental model(s). The survey obtained 171 viable responses and explored the general public’s investment habits and opinions of cryptocurrency. The survey found that while current economic conditions are impacting people’s investment habits, non-users of cryptocurrency felt it was not secure, that they didn’t understand it enough, and that it was too volatile. Additionally, 11 interviews were conducted with people who self-identified as heavy investors but did not currently own cryptocurrency. Recurring themes included influencers, knowledge, timing, mainstream adoption, motivation, risk, contentment with the status quo, investment strategies, and volatility. The mental model created from these opinions could be used by UX designers at financial institutions and fin-tech companies who are interested in introducing more customers to cryptocurrency.

description: Individuals seeking healthcare in rural America experience a simplified model of treatment in comparison to their metropolitan counterparts. When met with various ailments, rural residents turn to their primary care physicians for answers whereas those in medically dense regions are offered specialty care. When it comes to caring for individuals with neurodevelopmental disorders, accessing services to help manage a disorder’s trajectory can pose a significant burden. Be it a child with autism needing behavior therapy or a child with a learning disorder needing accommodations at school, insufficient resources can have a direct impact on the affected individual’s quality of life. I will investigate this issue throughout rural parts of North Carolina, seeking to demand the matter be provided the sense of urgency and attentiveness the disorders require. I will compile an anthology comprising of three long-form journalism pieces to examine the issue from a multi-lens perspective. I will approach my research in the following steps: 1) I will seek to understand what receiving a diagnosis means for families who are a. currently undergoing the process or b. who have recently undergone the process; 2) I will spend time with a young adult who was either a) misdiagnosed or b) diagnosed later in life in an attempt to understand what life is like for an individual when the key intervention period is missed; and 3) I will seek to learn the role rural environments play in improving or amplifying the challenges affected individuals face.

description: The ruling in the case of Alston v. NCAA revolutionized the world of college athletics. Student athletes are now allowed to market and profit off of their Name, Image, and Likeness. The interim NIL policies have been in place for a little over 20 months, and now programs, teams, athletic departments, and universities are adjusting to the new normal. Student athletes have the opportunity to negotiate and partner with companies and brands; in some cases the results have been incredibly lucrative. Social media has played a significant role in today’s society for over a decade, and it is the optimal outlet and platform for many NIL deals. With NIL, college athletics has become a business in more ways than one. Student athletes must market themselves and appeal to what brands and companies are looking for in an ambassador. As student athletes work to develop and strengthen their own personal brand, their partnership will become more appealing to potential brands. This resource will serve as a guide for student athletes to learn how to develop a strong personal brand, as well as how to optimize resources available to them through the university to exponentially increase their earning potential through NIL.

description: Background: Vascular involvement of Behcet’s disease (BD) involves both arterial and venous vessels of all sizes [1]. Femoral (superficial, deep, and common) and popliteal veins are the most frequently affected veins. We have previously shown that femoral wall thickness is increased in BD patients and can be used as a diagnostic test [2]. However, many other sites including vena cava inferior/superior and pulmonary arteries may also be involved [3]. Despite the dominance of venous vessel involvement, there is limited data assessing the large veins in BD. In this study, we aimed to assess inferior vena cava wall thickness (IVC) by transthoracic echocardiography (TTE) in BD compared with healthy controls. Methods: Patients with BD (n=70) and age and sex-matched healthy controls (n=51) were included in this study. Assessment of inferior vena cava (IVC) wall thickness was performed by an experienced cardiologist blinded to cases. Measurement of IVC wall thickness was made at end-expiration and approximately 0.5 to 2.0 cm proximal to the ostium of the right atrium as demonstrated in Figure 1. Results: IVC wall thickness of patients with BD (0.29 mm (SD: 0.03) was significantly higher than healthy controls (0.26 mm (SD: 0.03) (p<001). Although IVC wall thickness was higher in patients with BD with vascular involvement (0.30 mm (SD:0.04) and history of pulmonary embolism (0.30 mm (SD:0.04)), the difference did not reach statistical significance. There was no difference between IVC wall thicknesses in patients who used immunosuppressive and anti-TNF treatments due to major organ involvement, compared to those who did not. Similarly, no difference is observed between IVC thicknesses among Behcet’s patients according to age, gender and activity status at the last visit. Although no correlation was found between IVC wall thicknesses, disease duration, and BDCAF scores at the last visit in BD group, there was a low-grade correlation between age and VCI wall thickness (r=0.31, p=0.09). Conclusions: Increased IVC wall thickness shows vasculitic involvement of large venous structures in BD and can be easily measured by TTE which is an easily accessible, noninvasive modality without radiation. The role of IVC wall thickness assessment for the diagnosis or management of BD requires further studies. Disclosures: None Figure 1.

description: We argue that the proton multiplicities measured in Roman pot detectors at an electron ion collider can be used to determine centrality classes in incoherent diffractive scattering. Incoherent diffraction probes the fluctuations in the interaction strengths of multi-parton Fock states in the nuclear wavefunctions. In particular, the saturation scale that characterizes this multi-parton dynamics is significantly larger in central events relative to minimum bias events. As an application, we study the centrality dependence of incoherent diffractive vector meson production. We identify an observable which is simultaneously very sensitive to centrality triggered parton fluctuations and insensitive to details of the model.

description: A new Bayesian method for the analysis of folded pulsar timing data is presented that allows for the simultaneous evaluation of evolution in the pulse profile in either frequency or time, along with the timing model and additional stochastic processes such as red spin noise, or dispersion measure variations. We model the pulse profiles using `shapelets' - a complete ortho-normal set of basis functions that allow us to recreate any physical profile shape. Any evolution in the profiles can then be described as either an arbitrary number of independent profiles, or using some functional form. We perform simulations to compare this approach with established methods for pulsar timing analysis, and to demonstrate model selection between different evolutionary scenarios using the Bayesian evidence. %s The simplicity of our method allows for many possible extensions, such as including models for correlated noise in the pulse profile, or broadening of the pulse profiles due to scattering. As such, while it is a marked departure from standard pulsar timing analysis methods, it has clear applications for both new and current datasets, such as those from the European Pulsar Timing Array (EPTA) and International Pulsar Timing Array (IPTA).

Search for long-lived neutral particles decaying to quark-antiquark pairs in proton-proton collisions at sqrt(s) = 8 TeV

Year: 2014
Subjects: subject: High Energy Physics - Experiment (hep-ex)

description: A search is performed for long-lived massive neutral particles decaying to quark-antiquark pairs. The experimental signature is a distinctive topology of a pair of jets, originating at a secondary vertex. Events were collected with the CMS detector at the CERN LHC in proton-proton collisions at a centre-of-mass energy of 8 TeV. The data analyzed correspond to an integrated luminosity of 18.5 inverse femtobarns. No significant excess is observed above standard model expectations. Upper limits at 95% confidence level are set on the production cross section of a heavy neutral scalar particle, H, in the mass range of 200 to 1000 GeV, decaying promptly into a pair of long-lived neutral X particles in the mass range of 50 to 350 GeV, each in turn decaying into a quark-antiquark pair. For X with mean proper decay lengths of 0.4 to 200 cm, the upper limits are typically 0.5-200 fb. The results are also interpreted in the context of an R-parity-violating supersymmetric model with long-lived neutralinos decaying into a quark-antiquark pair and a muon. For pair production of squarks that promptly decay to neutralinos with mean proper decay lengths of 2-40 cm, the upper limits on the cross section are typically 0.5-3 fb. The above limits are the most stringent on these channels to date.

description: We report about recent researches of the long-lived meteor trails at the mesopause region and artificial increasing of the red airglow in the thermosphere due to the spacecraft engine activation. Observing with all-sky cameras show that the events appear as a spot or ring of the enhanced glow with diameter of hundreds of kilometers and have a lifetime from several minutes till tens of minutes. The phenomena appear at different height levels and have a different origin, whereas the dynamic in temporal and spatial domain as observed on the ground are similar. The data obtained can conclude that both phenomena have the same nature -influence of meteor matter or satellite engine products on the chemical reactions in the upper atmosphere. Statistics and stereoscopy of the events can give us the possibility to separate and control the moments of the satellite engine operations and perform the additional investigations of the mesopause region.

description: Within the Dirac model for the electronic excitations of graphene, we calculate the full polarization tensor with finite mass and chemical potential. It has, besides the (00)-component, a second form factor, which must be accounted for. We obtain explicit formulas for both form factors and for the reflection coefficients. Using these, we discuss the regions in the momentum-frequency plane where plasmons may exist and give numeric solutions for the plasmon dispersion relations. It turns out that plasmons exist for both, TE and TM polarizations over the whole range of the ratio of mass to chemical potential, except for zero chemical potential, where only a TE plasmon exists.

description: Resources and supportive services are available at the University of North Carolina at Chapel Hill (UNC) for those who have experienced sexual assault or sexual violence. However, students need to know about the available resources before they can benefit from them. This study investigates the extent to which students are aware of and familiar with the resources currently available. This was achieved through an online survey of the general student body including both undergraduate and graduate/professional students. More specifically, students were asked about their awareness of and knowledge about 13 resources in the Chapel Hill community. Students are most familiar with Campus Health, UNC Police, and Counseling and Psychological Services (CAPS) but there is a wide disparity in the level of familiarity with other resources. The findings of this research illustrate current student awareness of resources which the university can use to inform future community education strategies regarding sexual violence resources to fill gaps in community knowledge.

description: Background: This study aims to shed light on the number and type of incidental findings detected on positron emission tomography (PET)/CT in a cohort of patients with large vessel vasculitis (LVV). Methods: The scan reports from PET/CT studies along with the medical charts of a cohort of patients with LVV from a clinic in Edmonton, Alberta, Canada were retrospectively reviewed on Connect Care and Netcare. Incidental findings from PET/CT, along with follow up studies and their diagnosis were documented and analysed. Results: The disease activity of 40 patients, with an average age of 65.8 years, was investigated using PET/CT. A total of 59 incidental findings were found in 28 (70%) patients. Of these findings, 45.8% were in the abdomen and pelvis. The most common incidental finding was lymphadenopathy (11.9%). Subsequent investigations of 7 patients confirmed pathological aetiology in 3 patients and benign findings in 4 patients. Conclusions: Overall, out of the 40 patients studied with PET/CT, 7 (17.5%) had follow up investigations. Most of the incidental findings were insignificant, but a total of 3 (7.5%) patients needed further management for their incidental findings, this included metastatic adenocarcinoma, pheochromocytoma, and cerebral infarct. With the increased usage of PET/CT in the assessment of patients with LVV and older age, incidental findings may become a significant result. Further studies are needed to determine the significance of the relationship between these incidental findings and LVV. Disclosures: None

description: Adami et al. (2010) have detected several cluster candidates at z>0.5 as part of a systematic search for clusters in the Canada France Hawaii Telescope Legacy Survey, based on photometric redshifts. We focus here on two of them, located in the D3 field: D3-6 and D3-43. We have obtained spectroscopy with Gemini/GMOS and measured redshifts for 23 and 14 galaxies in the two structures. These redshifts were combined with those available in the literature. A dynamical and a weak lensing analysis were also performed, together with the study of X-ray Chandra archive data. Cluster D3-6 is found to be a single structure of 8 spectroscopically confirmed members at an average redshift z=0.607, with a velocity dispersion of 423 km/s. It appears to be a relatively low mass cluster. D3-43-S3 has 46 spectroscopically confirmed members at an average redshift z=0.739. It can be decomposed into two main substructures, having a velocity dispersion of about 600 and 350 km/s. An explanation to the fact that D3-43-S3 is detected through weak lensing (only marginally, at the ~3sigma level) but not in X-rays could be that the two substructures are just beginning to merge more or less along the line of sight. We also show that D3-6 and D3-43-S3 have similar global galaxy luminosity functions, stellar mass functions, and star formation rate (SFR) distributions. The only differences are that D3-6 exhibits a lack of faint early type galaxies, a deficit of extremely high stellar mass galaxies compared to D3-43-S3, and an excess of very high SFR galaxies. This study shows the power of techniques based on photometric redshifts to detect low to moderately massive structures, even at z~0.75.

Human-computer interaction

description: The internet has become an integral part of people’s lives. However, any digital activity results in energy consumption and greenhouse gas emissions, which are the prime drivers of global warming and climate change. The environmental cost calls for the practice of sustainable web design or green human-computer interaction. While there is substantial research on ways to reduce the energy consumption of the back-end information systems, such as data centers, few studies focus on the front-end information systems, such as web design.

description: In light of recent proposals to realize a topological superconductor on the surface of strong topological insulators, we study impurity and vortex scattering in two dimensional topological superconductivity. We develop a theory of quasiparticle interference in a model of the surface of a three dimensional strong topological insulator with a pairing term added. We consider a variety of different scatterers, including magnetic and nonmagnetic impurity as well as a local pairing order parameter suppression associated with the presence of a vortex core. Similar to the case of a surface of a three dimensional topological insulator without pairing, our results for non-magnetic impurity can be explained by the absence of back scattering, as expected for a Dirac cone structure. In the superconducting case, doping away from the Dirac point leads to a doubling of the contours of constant energy. This is in contrast to the unpaired case where the chemical potential simply adds to the bias voltage and shifts the energy. This doubling of contours results in multiplying the number of possible scattering processes in each energy. Interestingly, we find that some processes are dominant in the impurity case while others are dominant in the vortex case. Moreover, the two types of processes lead to a different dependence on the chemical potential.

description: We develop a semi-analytic method for assessing the impact of the large-scale IGM temperature fluctuations expected following He${\rm\,{\scriptstyle II}}$ reionization on three-dimensional clustering measurements of the Ly$α$ forest. Our methodology builds upon the existing large volume, mock Ly$α$ forest survey simulations presented by Greig et al. by including a prescription for a spatially inhomogeneous ionizing background, temperature fluctuations induced by patchy He${\rm\,{\scriptstyle II}}$ photoheating and the clustering of quasars. This approach enables us to achieve a dynamic range within our semi-analytic model substantially larger than currently feasible with computationally expensive, fully numerical simulations. The results agree well with existing numerical simulations, with large-scale temperature fluctuations introducing a scale-dependent increase in the spherically averaged 3D Ly$α$ forest power spectrum of up to 20-30 per cent at wavenumbers $k\sim0.02$ Mpc$^{-1}$. Although these large-scale thermal fluctuations will not substantially impact upon the recovery of the baryon acoustic oscillation scale from existing and forthcoming dark energy spectroscopic surveys, any complete forward modelling of the broad-band term in the Ly$α$ correlation function will none the less require their inclusion.

description: Background: Iliofemoral artery disease, which is commonly observed in severe atherosclerosis, may also be present in Takayasu’s arteritis (TAK). In this study we aimed to evaluate the characteristics of TAK patients with or without iliofemoral artery involvement in PET/CT. Methods: Patients fulfilling ACR 1990 classification criteria for TAK and underwent PET-CT imaging were evaluated retrospectively. Demographic and clinical data were collected from patients’ charts. Traditional cardiovascular risk factors: diabetes, hypertension, hyperlipidaemia, smoking history and body mass index (BMI) were recorded. PET Vascular Activity Score (PETVAS) was used to assess the quantitative PET activity. Results: Seventy-one PET/CT scans of 52 (F/M: 42/10) patients with TAK were investigated. Mean age was 42.8±14.2 years and mean disease duration 5.6 ±5.3 years. The aortic arch (75%) was the most commonly involved artery. Iliofemoral arteries were involved in 9 (13%) patients. Patients with iliofemoral involvement were older (52.5±17.4 vs 39.9±12.4 years, p=0.036), had lower glucocorticoid (GC) dose (0 (0-7.5) vs 2.5 mg/day (0-80), p=0.049), higher CRP (36.1±28.1 vs 19.7±25.0 mg/L, p=0.041) and higher PETVAS (11.4±9.7 vs 4.2±3.9, p=0.018). Male gender (50% vs 14%, p=0.016) and current smokers (78% vs 35%, p=0.016) were also more present in the iliofemoral involvement group. Conclusions: Involvement of iliofemoral arteries in PET/CT in TAK patients are associated with atherosclerotic risk factors more frequently. Therefore, anti-atherosclerotic approaches should be implemented more vigorously during the follow-up of TAK patients with lower extremity involvement. Disclosures: None Table 1.

Impact of anisotropic stress of free-streaming particles on gravitational waves induced by cosmological density perturbations

description: Gravitational waves (GWs) are inevitably induced at second-order in cosmological perturbations through non-linear couplings with first order scalar perturbations, whose existence is well established by recent cosmological observations. So far, the evolution and the spectrum of the secondary induced GWs have been derived by taking into account the sources of GWs only from the product of first order scalar perturbations. Here we newly investigate the effects of purely second-order anisotropic stresses of photons and neutrinos on the evolution of GWs, which have been omitted in the literature. We present a full treatment of the Einstein-Boltzmann system to calculate the spectrum of GWs with anisotropic stress based on the formalism of the cosmological perturbation theory. We find that photon anisotropic stress amplifies the amplitude of GWs by about $150 %$ whereas neutrino anisotropic stress suppress that of GWs by about $30 %$ on small scales $k\gtrsim 1.0 h{\rm Mpc}^{-1}$ compared to the case without anisotropic stress. The second order anisotropic stress does not affect GWs with wavenumbers $k\lesssim 1.0 h{\rm Mpc}^{-1}$. The result is in marked contrast with the case at linear order, where the effect of anisotropic stress is damping in amplitude of GWs.

description: The Aurora Subglacial Basin (ASB) in East Antarctica contains at least 3.5 meters of eustatic sea level potential in ice grounded below sea level, primarily draining through Totten Glacier into the Sabrina Coast. Totten’s coastal grounded ice has been thinning faster than any other glacier system in East Antarctica since the beginning of the satellite altimetry record and its grounding line has been retreating since at least 1996. Recent work has shown that a vast subglacial hydrological system underlies the Totten Glacier Catchment, likely providing important controls on ice dynamics. Ice-flow acceleration is directly linked to the distribution of subglacial hydrology; for example, a channelized or otherwise centralized hydrological system streamlines water loss without increasing basal lubrication, while distributed systems can increase lubrication and therefore ice flow. To predict the future behavior of this sensitive area, we must improve our understanding of the characteristics of the subglacial flow. Recent work applying the Glacier Drainage System (GlaDS) model applied to the ASB revealed a varied hydrological system beneath the Totten Glacier Catchment with channelization occurring within 200 km of the Totten grounding line. While the model provides a compelling picture of the glacier, the ice-penetrating radar survey coverage available at the time was not optimized for testing for the presence or absence of water in the modeled locations. Using newly-acquired aerogeophysical data, we provide a systematic comparison of inferred basal character and the modeled hydrological setting to test for a transition from a distributed to concentrated water system upstream of Totten’s grounding line. With these new data, we provide an updated picture of the subglacial system beneath Totten Glacier.
Searches for heavy long-lived charged particles with the ATLAS detector in proton-proton collisions at $\sqrt{s}$ = 8 TeV

description: Searches for heavy long-lived charged particles are performed using a data sample of 19.8 fb$^{-1}$ from proton-proton collisions at a centre-of-mass energy of $\sqrt{s}$ = 8 TeV collected by the ATLAS detector at the Large Hadron Collider. No excess is observed above the estimated background and limits are placed on the mass of long-lived particles in various supersymmetric models. Long-lived tau sleptons in models with gauge-mediated symmetry breaking are excluded up to masses between 440 and 385 GeV for $\tanβ$ between 10 and 50, with a 290 GeV limit in the case where only direct tau slepton production is considered. In the context of simplified LeptoSUSY models, where sleptons are stable and have a mass of 300 GeV, squark and gluino masses are excluded up to a mass of 1500 and 1360 GeV, respectively. Directly produced charginos, in simplified models where they are nearly degenerate to the lightest neutralino, are excluded up to a mass of 620 GeV. $R$-hadrons, composites containing a gluino, bottom squark or top squark, are excluded up to a mass of 1270, 845 and 900 GeV, respectively, using the full detector; and up to a mass of 1260, 835 and 870 GeV using an approach disregarding information from the muon spectrometer.

Authors

description: This study aims to identify and describe creative writer information-seeking behavior and creative writer information-seeking behavior for visual studies materials, using methodology adapted from visual artist information-seeking research. Data were gathered through semi-structured interviews with a purposive sample of six creative writers: three poets and three fiction writers. Conversations were coded for information motivations, sources, formats, access concerns, and applications; search behaviors; and forms of visual studies engagement. This study contributes to our understanding of the information-seeking behavior of creative writers from an information science perspective, a topic that as of 2022 continues to be under explored within information science. Additionally, this research supports examination of visual studies material audiences, access, discoverability, and organization; opportunities for and approaches to art library outreach; and interdisciplinary subject collaborations in the library.

description: In this paper, we first investigate an abstract subdifferential for which (using Ekeland's variational principle) we can prove an analog of the Brøndsted-Rockafellar property. We introduce the "$r_L$-density" of a subset of the product of a Banach space with its dual. A closed $r_L$-dense monotone set is maximally monotone, but we will also consider the case of nonmonotone closed $r_L$-dense sets. As a special case of our results, we can prove Rockafellar's result that the subdifferential of a proper convex lower semicontinuous function is maximally monotone.
