description: Open access has changed. At the beginning of the millennium, it was portrayed in a romanticizing way and was embedded in a conceptual ensemble of participation, democratization, digital commons and equality. Nowadays, open access seems to be exclusive: to the extent that commercial players have discovered it as a business model and article fees have become a defining feature of gold open access, open access has increasingly transformed into a distinguishing feature and an exclusive element. Scientists are beginning to make the choice of a university or research institution as an employer based on whether or not they can afford to cover the article fees for publications in high-impact but high-priced journals. Surprisingly, this transformation of open access is not the subject of any noteworthy discussion in specialist or journalistic publications, but instead the ideals of the digital commons of knowledge still prevail in these venues. Even so open access is increasingly becoming an instrument that creates exclusivity, exclusion, distinction and prestige. These functions, however, are obscured by symbolic gift giving strategies and presented as altruistically staged, so that in the discourse of the open access community and in media reporting on open access, the both euphemistic and largely obsolete prosocial story-telling of open access dominates. The paper also discusses the question of whether the concept of open access was not overstrained by the hopes placed in it.
title: Healthcare Screenings in the Occupational and Workplace Setting: Taking Control Over Blood Pressure
Creators: name: Horton, Darryl
Publisher: name: University of Nevada, Las Vegas

description: Undiagnosed hypertension continues to be a growing concern worldwide leading to cardiovascular disease and other chronic illnesses and can contribute to death. The prevalence of hypertension continues to increase even with guidelines on screening, hypertension education, disease prevention, disease maintenance, and management. The purpose of this project was to determine if the implementation of a workplace blood pressure screening program would improve hypertension knowledge and reduce the burden of hypertension within workplace. A descriptive, cross-sectional design using convenience sampling was conducted. Participants were screened by measuring blood pressures, and the Hypertension Evaluation of Lifestyle Management scale (HELM) was utilized to assess participants’ hypertension knowledge pre/post intervention. Home Blood Pressure Monitoring (HBPM) devices were utilized for two weeks, followed by a 30-day follow-up. Paired t-test of pre/post systolic blood pressure (SBP) and diastolic blood pressure (DBP) showed significant improvement in DBPs only. Lastly, the paired t-test of the HELM scale scores showed significant changes in hypertension knowledge post intervention. Findings from this Doctor of Nursing Practice Project resulted in a significant short-term improvement of DBP and increased hypertension knowledge. This project laid a foundation for future studies on the importance of screening practices, use of patient specific education (evidence-based), and the importance of the use of HBPM in hypertension screening.
Enumerative geometry of GIT quotients
Creators: name: Shafi, Mohammed Qaasim
Publisher: name: Imperial College London
Year: 2022

description: In this thesis we study the enumerative geometry of certain GIT quotients. Chapter 2 details work (joint with T. Coates and W. Lutz) on the comparison between genus-zero Gromov–Witten invariants of X and of a blow up of X. We do this by rewriting a blow up as a subvariety of a certain GIT quotient and extending the Abelian/non-Abelian correspondence, which compares genus-zero Gromov–Witten invariants of a GIT quotient by a non-abelian group with the corresponding quotient by the maximal torus. We also give a reformulation of the Abelian/non-Abelian correspondence in terms of Givental’s Lagrangian cones, which suggests a relationship in higher genus. In Chapter 3 we build a theory of logarithmic quasimaps for smooth projective toric varieties relative a simple normal crossings divisor in any genus. To do this we construct a proper Deligne–Mumford moduli stack compactifying the space of quasimaps from smooth marked curves of fixed degree and genus satisfying prescribed tangency conditions to the divisor at the markings. We give a sketch of the construction of the virtual fundamental class using the formalism of Behrend and Fantechi. We then look at how this theory interacts with the local-logarithmic correspondence.

description: Robotic agents trained using reinforcement learning have the problem of taking unreliable actions in an out-of-distribution (OOD) state. Agents can easily become OOD in real-world environments because it is almost impossible for them to visit and learn the entire state space during training. Unfortunately, unreliable actions do not ensure that agents perform their original tasks successfully. Therefore, agents should be able to recognize whether they are in OOD states and learn how to return to the learned state distribution rather than continue to take unreliable actions. In this study, we propose a novel method for retraining agents to recover from OOD situations in a self-supervised manner when they fall into OOD states. Our in-depth experimental results demonstrate that our method substantially improves the agent's ability to recover from OOD situations in terms of sample efficiency and restoration of the performance for the original tasks. Moreover, we show that our method can retrain the agent to recover from OOD situations even when in-distribution states are difficult to visit through exploration.

description: We study experimentally and theoretically the dynamics of apparent dark soliton stripes in an elongated Bose-Einstein condensate. We show that for the trapping strengths corresponding to our experimental setup, the transverse confinement along one of the tight directions is not strong enough to arrest the formation of solitonic vortices or vortex rings. These solitonic vortices and vortex rings, when integrated along the transverse direction, appear as dark soliton stripes along the longitudinal direction thereby hiding their true character. The latter significantly modifies the interaction dynamics during collision events and can lead to apparent examples of inelasticity and what may appear experimentally even as a merger of two dark soliton stripes. We explain this feature by means of the interaction of two solitonic vortices leading to a sling shot event with one of the solitonic vortices being ejected at a relatively large speed. Furthermore we observe expanding collision bubbles which consist of repeated inelastic collisions of a dark soliton stripe pair with an {\it increasing} time interval between collisions.

title: “Who Says Lowriders Are Only For Men?”: Lowriders In Las Vegas, Nevada
Creators: name: Herrera, Alejandra
Publisher: name: University of Nevada, Las Vegas
Year: 2022

description: Since its creation, Las Vegas, Nevada, has been associated with casinos, nightlife, drinking, and neon lights. Las Vegas is not associated with Lowriders. Historically, lowrider vehicles are associated with crime, gangs, and male drivers. When lowriding comes to mind, Lowriders are associated with major cities in California, Texas, New Mexico, Arizona, and Colorado. Lowriders are not usually visualized as having female participants or as being present in Las Vegas. This thesis highlights members of the Lowrider community (especially Christal Leyva, Ivelys Franco, and Juanita Salazar) through the use of oral interviews and personal correspondence. The Lowriders interviewed for this thesis are a local, Las Vegas Lowriders. Women in the lowriding scene provide critical contributions to the local lowriding community through their advocacy of uplifting other women and their autonomy as women. Seldomly are Lowrider women mentioned in the Lowrider scholarship. Thus, the roles of Leyva, Franco, and Salazar should not be disregarded because they provide insight into a gap within Lowrider scholarship by the Lowriders being women who reside in Las Vegas, Nevada.

description: The increasing availability of computers to ordinary users in the last few decades has led to an exponential increase in the use of Corpus Linguistics (CL) methodologies. The people exploring this data come from a variety of backgrounds and, in many cases, are not proficient corpus linguists. Despite the ongoing development of new tools, there is still an immense gap between what CL can offer and what is currently being done by researchers. This study has two outcomes. It (a) identifies the gap between potential and actual uses of CL methods and tools, and (b) enhances the usability of CL software and complement statistical application through the use of data visualization and user-friendly interfaces. The first outcome is achieved through (i) an investigation of how CL methods are reported in academic publications; (ii) a systematic observation of users of CL software as they engage in the routine tasks; and (iii) a review of four well-established pieces of software used for corpus exploration. Based on the findings, two new statistical tools for CL studies with high usability were developed and implemented on to an existing system, CQPweb. The Advanced Dispersion tool allows users to graphically explore how queries are distributed in a corpus, which makes it easier for users to understand the concept of dispersion. The tool also provides accurate dispersion measures. The Parlink Tool was designed having as its primary target audience beginners with interest in translations studies and second language education. The tool’s primary function is to make it easier for users to see possible translations for corpus queries in the parallel concordances, without the need to use external resources, such as translation memories.

Nonlinear rheology of dense colloidal systems with short-ranged attraction: A mode-coupling theory analysis

Year: 2014

description: The nonlinear rheology of glass-forming colloidal suspensions with short-ranged attractions is discussed within the integration-through transients framework combined with the mode-coupling theory of the glass transition (ITT-MCT). Calculations are based on the square-well system (SWS), as a model for colloid-polymer mixtures. The high-density regime featuring reentrant melting of the glass upon increasing the attraction strength, and the crossover from repulsive glasses formed at weak attraction to attractive glasses formed at strong attraction, are discussed. Flow curves are found in qualitative agreement with experimental data, featuring a strong increase in the yield stress, and, for suitable interaction parameters, the crossover between two yield stresses. The yield strain, defined as the position of the stress overshoot under startup flow, is found to be proportional to the attraction range for strong attraction. At weak and intermediate attraction strength, the combined effects of hard-core caging and attraction-driven bonding result in a richer dependence on the parameters. The first normal-stress difference exhibits a weaker dependence on short-ranged attractions as the shear stress, since the latter is more sensitive the short-wavelength features of the static structure.

description: We report analysis of transit spectroscopy of the extrasolar planets WASP-12 b, WASP-17 b, and WASP-19 b using the Wide Field Camera 3 on the HST. We analyze the data for a single transit for each planet using a strategy similar in certain aspects to the techniques used by Berta et al. (2012), but we extend their methodology to allow us to correct for channel- or wavelength-dependent instrumental effects by utilizing the band-integrated time series and measurements of the drift of the spectrum on the detector over time. We achieve almost photon-limited results for individual spectral bins, but the uncertainties in the transit depth for the the band-integrated data are exacerbated by the uneven sampling of the light curve imposed by the orbital phasing of HST's observations. Our final transit spectra for all three objects are consistent with the presence of a broad absorption feature at 1.4 microns potentially due to water. However, the amplitude of the absorption is less than that expected based on previous observations with Spitzer, possibly due to hazes absorbing in the NIR or non-solar compositions. The degeneracy of models with different compositions and temperature structures combined with the low amplitude of any features in the data preclude our ability to place unambiguous constraints on the atmospheric composition without additional observations with WFC3 to improve the S/N and/or a comprehensive multi-wavelength analysis.

description: Sustainable software ecosystems are difficult to build, and require concerted effort, community norms and collaborations. In science it is especially important to establish communities in which faculty, staff, students and open-source professionals work together and treat software as a first-class product of scientific investigation-just as mathematics is treated in the physical sciences. Kitware has a rich history of establishing collaborative projects in the science, engineering and medical research fields, and continues to work on improving that model as new technologies and approaches become available. This approach closely follows and is enhanced by the movement towards practicing open, reproducible research in the sciences where data, source code, methodology and approach are all available so that complex experiments can be independently reproduced and verified.

description: We show that thermal creep is at the origin of the recently discovered Leidenfrost ratchet, where liquid droplets float on a vapor layer along a heated sawtooth surface and accelerate to velocities of up to 40 cm=s. As the active element, the asymmetric temperature profile at each ratchet summit rectifies the vapor flow in the boundary layer. This mechanism works at low Reynolds number and provides a novel tool for controlling gas flow at nanostructured surfaces.

title: Improving Nurse Leaders’ Knowledge and Confidence in Transformational Leadership Skills in the Online Environment
Creators: name: Haight, Tanya
Publisher: name: University of Nevada, Las Vegas
Year: 2022

description: Leadership is critical to the success of most organizations, and the achievement of an organization's goals is largely dependent on the leaders' ability to engage, motivate, and influence their teams—often referred to as Transformational Leadership. This is especially true for healthcare organizations wherein the morbidity and mortality of patients may be affected by the quality of leadership. At the start of the COVID-19 pandemic, in-person meetings transitioned to the online format without nurse leaders' formal training. Leaders cited this lack of orientation as impeding their ability to sustain an online-virtual transformational leadership presence with their teams. They reported varying degrees of competence in virtual leadership, which are likely to persist without formal training and education. Research shows that leadership practices must adapt to the virtual environment for effective leadership and sustainable performance. However, little research focused on competency-based education teaching nurse leaders to be knowledgeable and confident transformational leaders in the online environment. The purpose of this Doctor of Nursing Practice (DNP) project was to develop, implement, and evaluate online modules to improve nurse leader knowledge and confidence of AONL leadership competencies, including communication and relationship management, in the online environment and within the context of transformational leadership. The target population was formal nurse leaders—directors, managers, and assistant nurse managers. After the education intervention, study findings revealed a significant increase in nurse leaders' knowledge and confidence in online, transformational leadership competency.
title: Psychometric Properties of the Eating Disorder Examination Questionnaire: Factor Analysis and Measurement Invariance by the Intersection of Race and Gender
Creators: name: Habashy, Jessica
Publisher: name: University of Nevada, Las Vegas
Year: 2022

description: The Eating Disorder Examination Questionnaire (EDE-Q) was originally validated in non-Hispanic White women and over the past two decades has become widely used as an eating pathology screening measure in college students. However, the original factor structure has generally failed to replicate across most studies, particularly among culturally diverse samples. The current study examined the factor structure and measurement invariance of the EDE-Q in a large sample of gender and racially/ethnically diverse college students. Participants included a racially and ethnically diverse sample of men and women from two universities. I first conducted exploratory factory analysis (EFA) to examine the factor structure of the EDE-Q, followed by confirmatory factor analysis (CFA) to verify the factor structure in order to establish the configural model. Next, I explored measurement invariance with the configural model by gender and race/ethnicity. CFA supported a three-factor, 10-item measure reflecting dietary restraint, preoccupation and eating concern, and shape/weight overvaluation. This measure achieved strict invariance by gender and race/ethnicity. Women, relative to men, reported higher scores for shape/weight overvaluation and preoccupation and eating concern. Significant differences among racial and ethnic groups were found among shape/weight overvaluation in which Hispanic individuals endorsed the highest scores. The three-factor, 10-item measure is a brief, valid, and reliable measure of eating disorder psychopathology for US college students. Routine screening of eating disorders among college campuses using this modified measure may promote early identification of eating disorders among young adults.

description: The classifications of Fermi-LAT unassociated sources are studied using multiple machine learning (ML) methods. The update data from 4FGL-DR3 are divided into high Galactic latitude (HGL, Galactic latitude $|b|>10^\circ$) and low Galactic latitude (LGL, $|b|\le10^\circ$) regions. In the HGL region, a voting ensemble of four binary ML classifiers achieves a 91$\%$ balanced accuracy. In the LGL region, an additional Bayesian-Gaussian (BG) model with three parameters is introduced to eliminate abnormal soft spectrum AGNs from the training set and ML-identified AGN candidates, a voting ensemble of four ternary ML algorithms reach an 81$\%$ balanced accuracy. And then, a catalog of Fermi-LAT all-sky unassociated sources is constructed. Our classification results show that (i) there are 1037 AGN candidates and 88 pulsar candidates with a balanced accuracy of $0.918 \pm 0.029$ in HGL region, which are consistent with those given in previous all-sky ML approaches; and (ii) there are 290 AGN-like candidates, 135 pulsar-like candidates, and 742 other-like candidates with a balanced accuracy of $0.815 \pm 0.027$ in the LGL region, which are different from those in previous all-sky ML approaches. Additionally, different training sets and class weights were tested for their impact on classifier accuracy and predicted results. The findings suggest that while different training approaches can yield similar model accuracy, the predicted numbers across different categories can vary significantly. Thus, reliable evaluation of the predicted results is deemed crucial in the ML approach for Fermi-LAT unassociated sources.

description: We demonstrate the existence of one and two-dimensional bright solitons in the Bose-Einstein condensate with repulsive dipole-dipole interactions induced by a combination of dc and ac polarizing fields, oriented perpendicular to the plane in which the BEC is trapped, assuming that the strength of the fields grows in the radial ($r$) direction faster than $r^{3}$. Stable tightly confined 1D and 2D fundamental solitons, twisted solitons in 1D, and solitary vortices in 2D are found in a numerical form. The fundamental solitons remain robust under the action of an expulsive potential, which is induced by the interaction of the dipoles with the polarizing field. The confinement and scaling properties of the soliton families are explained analytically. The Thomas-Fermi approximation is elaborated for fundamental solitons. The mobility of the fundamental solitons is limited to the central area. Stable 1D even and odd solitons are also found in the setting with a double-well modulation function, along with a regime of Josephson oscillations.

description: Many animals produce coordinated signals, but few are more striking than the elaborate male–female vocal duets produced by some tropical songbirds. Yet, little is known about the factors driving the extreme levels of vocal coordination between mated pairs in these taxa. We examined evolutionary patterns of duet coordination and their potential evolutionary drivers in Neotropical wrens (Troglodytidae), a songbird family well known for highly coordinated duets. Across 23 wren species, we show that the degree of coordination and precision with which pairs combine their songs into duets varies by species. This includes some species that alternate their song phrases with exceptional coordination to produce rapidly alternating duets that are highly consistent across renditions. These highly coordinated, consistent duets evolved independently in multiple wren species. Duet coordination and consistency are greatest in species with especially long breeding seasons, but neither duet coordination nor consistency are correlated with clutch size, conspecific abundance or vegetation density. These results suggest that tightly coordinated duets play an important role in mediating breeding behaviour, possibly by signalling commitment or coalition of the pair to mates and other conspecifics.

description: The origin of rapid neutron capture (r-process) nuclei remains one of the longest standing mysteries in nuclear astrophysics. Core collapse supernovae (SNe) and neutron star binary mergers are likely r-process sites, but little evidence yet exists for their in situ formation in such environments. Motivated by the advent of sensitive new or planned X-ray telescopes such as the Nuclear Spectroscopic Telescope Array (NuSTAR) and the Large Observatory for X-ray Timing (LOFT), we revisit the prospects for the detection of X-ray decay lines from r-process nuclei in young or nearby supernova remnants. For all remnants planned to be observed by NuSTAR (and several others), we conclude that r-process nuclei are detectable only if the remnant possesses a large overabundance O > 1e3 relative to the average yield per SN. Prospects are better for the next Galactic SN (assumed age of 3 years and distance of 10 kpc), for which an average r-process yield is detectable via the 10.7(9.2) keV line complexes of Os194 by LOFT at 6 sigma (5 sigma) confidence; the 27.3 keV line complex of Sb125 is detectable by NuSTAR at 2 sigma for O > 2. We also consider X-rays lines from the remnants of Galactic magnetars, motivated by the much higher r-process yields of the magneto-rotationally driven SNe predicted to birth magnetars. The ~ 3.6-3.9 keV lines of Sn126 are potentially detectable in the remnants of the magnetars 1E1547.0-5408 and 1E2259+586 by LOFT for an assumed r-process yield predicted by recent simulations. The (non-)detection of these lines can thus probe whether magnetars are indeed born with millisecond periods. Finally, we consider a blind survey of the Galactic plane with LOFT for r-process lines from the most recent binary neutron star merger remnant, concluding that a detection is unlikely without additional information on the merger location.

title: Changes in Cognitive Networks as a Result of Sport-Related Concussion
Creators: name: Goodwin, Grace
Publisher: name: University of Nevada, Las Vegas
Year: 2022

description: Given the high prevalence of concussion in sports, assessment of cognition has become a standard part of athletics, and results are used to inform return to play decisions. Neurocognitive measures (e.g., ImPACT) generate cognitive composite scores from individual subtests, and these scores are compared at baseline and post-concussion. Declines in scores provide evidence for concussive injury, and athletes undergo repeated assessments until their scores and symptoms improve. Recent research suggests that changes in the associations between test scores may provide important information about cognitive recovery. A network framework may help identify post-concussive cognitive changes that may not be apparent when composite scores are compared. The present study examined composite-level comparisons and network-level comparisons to see whether network models could better characterize SRC recovery. Athletes were administered ImPACT at preseason and post-SRC (acute assessment = 72 hours of injury, recovery assessment = within two weeks post-injury). Repeated measures ANOVA was conducted to examine differences in composite scores over time. Cognitive networks were estimated for the baseline, acute, and recovery assessment time points. Centrality indices were calculated to determine relative importance of each cognitive variable in each network. Network comparison tests were conducted to examine differences in network structure, connectedness, and centrality over time. Repeated measures ANOVA results revealed an initial decline in composite scores acutely post-SRC followed by improvement in scores at recovery. Network analysis results indicated significantly increased network connectivity in both the acute and recovery networks compared to the baseline network. Additionally, network structure changed significantly from baseline to recovery. Visual memory and processing speed nodes were highly central and influential within each network. Network comparisons also revealed changes in centrality over time. Specifically, visual memory nodes became more central and influential over time, and impulsivity nodes became more central from acute to recovery. While composite scores suggested cognitive recovery, cognitive network comparisons revealed lingering network disruption at the recovery time point. Increased connectivity may reflect increased effort to complete cognitive tasks, while changes in network structure suggest that compensatory strategies may be used to achieve task demands. Given that visual memory and impulsivity played an increasingly central role in networks over time, it may be helpful to target these processes during treatment. Future research should examine whether certain pre-injury characteristics (e.g., neurodevelopmental history) moderate longitudinal changes in cognitive networks.

description: Livestreaming has rapidly become a popular online pastime, with real-time interaction between streamer and viewer being a key motivating feature. However, viewers have traditionally had limited opportunity to directly influence the streamed content; even when such interactions are possible, it has been reliant on text-based chat. We investigate the potential of spatial interaction on the livestreamed video content as a form of direct, real-time input for livestreamed applications. We developed VIBES, a flexible digital system that registers viewers' mouse interactions on the streamed video, i.e., clicks or movements, and transmits it directly into the streamed application. We used VIBES as a technology probe; first designing possible demonstrative interactions and using these interactions to explore streamers' perception of viewer influence and possible challenges and opportunities. We then deployed applications built using VIBES in two livestreams to explore its effects on audience engagement and investigate their relationships with the stream, the streamer, and fellow audience members. The use of spatial interactions enhances engagement and participation and opens up new avenues for both streamer-viewer and viewer-viewer participation. We contextualize our findings around a broader understanding of motivations and engagement in livestreaming, and we propose design guidelines and extensions for future research.

title: Women’s Use of the Gym Space: How Physical Activity Spaces Communicate Inclusion and Exclusion to Women
Creators: name: Glaze, Rachel
Publisher: name: University of Nevada, Las Vegas

description: Women are less likely than men to participate in recommended levels of physical activity. As gyms are built around exercise, this research sought to understand if women’s gym participation is limited, due to the space communicating messages of exclusion. Semi-structured interviews with seven women participants led to the discovery of three themes surrounding women’s experiences in the gym setting: Comfort and confidence in the space stem from self-perceived levels of attractiveness, women treat the space as communal to better understand how to navigate it, and organizational spaces can communicate messages of class and socioeconomic differences. Recommendations for future research included minimizing feelings of intimidation and polarization in recreational spaces, particularly in terms of gender and class.
title: Decreasing Central Line-Associated Bloodstream Infections in the Critical Care Unit
Creators: name: Foxworth, Kimberly

description: Central line-associated bloodstream infections (CLABSI) are a rising problem in the critical care setting in the United States. According to Flogren et al. (2007), "an estimated 248,000 bloodstream infections occur in hospitals across the United States each year, and a significant amount of these infections are associated with the use of a central venous catheter" (p.160). The Center for Disease Control and Prevention (CDC) defines a CLABSI as "recovery of a pathogen from blood culture (a single blood culture for organisms not commonly present on the skin and two or more blood cultures for organisms commonly present on the skin) in a patient who had a central line at the time of infection or within the 48 hours before the development of infection" ("Vital Signs: Central Line-Associated Blood Stream Infections—United States, 2001, 2008, and 2009," 2011, p. 447). After forty-eight hours, the development of a CLABSI most often points to infection attributed to central line placement or maintenance. The U.S. Department of Health and Human Services noted CLABSIs as a significant concern and, in 2009, set a national goal for a 50% reduction in CLABSIs by 2013 (Wise et al., 2013). Since then, however, hospital systems across the United States have been challenged with meeting this goal. This project aims to improve the efficacy of the CLABSI bundle currently used in the critical care setting by implementing nursing interventions supported by evidence-based practice that will help prevent the incidence of CLABSI in the acute care patient population.
title: Queens of Discourse: An Observation of Black Insta-Comediennes
Creators: name: Foreman, Naoka
Publisher: name: University of Nevada, Las Vegas
Year: 2022

description: This study observed the ways Black females on Instagram perform sociopolitical humor online to push back against the dominant culture in this digital age – maintaining the Black comedy tradition. It explores and illuminates the strategies of resistance exhibited by Instagram comediennes through a textual analysis informed by minor discourse, intersectionality, and critical feminist theories. Each comic’s personae were investigated and their content on Instagram was randomly selected and coded then grouped into themes. Black insta-comediennes shared Black feminist thought, modified beliefs about Black females or conventionality, and negotiated with the industrial demands of show business to earn subjectivity on Instagram and their actions revealed how the platform is uniquely adjacent to mainstream media. This gave Black women room to forward Black women's epistemology in cyberspace to ultimately subvert negative stereotypes of Black women and give voice to the modern Black female experience – with millions of views.
Measurement-induced generation of spatial entanglement in a two-dimensional quantum walk with single-qubit coin

description: One of the proposals for the exploitation of two-dimensional quantum walks has been the efficient generation of entanglement. Unfortunately, the technological effort required for the experimental realization of standard two-dimensional quantum walks is significantly demanding. In this respect, an alternative scheme with less challenging conditions has been recently studied, particularly in terms of spatial-entanglement generation [C. Di Franco, M. Mc Gettrick, and Th. Busch, Phys. Rev. Lett. 106, 080502 (2011)]. Here, we extend the investigation to a scenario where a measurement is performed on the coin degree of freedom after the evolution, allowing a further comparison with the standard two-dimensional Grover walk.

title: Family Functioning in Youth with Bipolar Disorder
Creators: name: Fobian, Kayla
Publisher: name: University of Nevada, Las Vegas
Year: 2022

description: Family functioning encompasses a family’s ability to maintain an environment that supports and benefits each member of the family. Among families of youth with a bipolar disorder (BD), family functioning is impaired compared to healthy controls. However, few studies have examined family functioning across psychopathology in youth. Additionally, few studies have examined which symptoms (depressive, manic, or externalizing) are most strongly associated with family functioning. Therefore, the purpose of this manuscript is to benchmark impairments in family functioning in youth with BD compared to youth with other psychiatric disorders and to examine the differential influence of depressive, manic, and comorbid externalizing behavior symptoms on family functioning in youth with BD. Youth with BD had more impaired family functioning compared to youth with behavior disorders and youth with non-mood, non-behavior disorders, but not youth with unipolar depression. Specifically, depressive and externalizing symptoms were most strongly associated with declines in both caregiver-reported and clinician-reported family functioning. (Hypo)manic symptoms were mostly unassociated with changes in family functioning. Depressive and externalizing symptoms appear to be driving declines in family functioning among youth with BD, making these symptoms critical targets for treatment of BD in youth.
Slow-mode rarefaction and compression fronts in the Hermean magnetosphere: From MESSENGER insights to future BepiColombo observations

description: Context. Standing slow-mode rarefaction and compression front structures may appear in the Mercury magnetosheath under particular solar wind conditions. Aims. The aim of the study is to identify the wind conditions required for the formation of slow-mode structures (SMS) in the Mercury magnetosphere by comparing MESSENGER magnetometer data and magnetohydrodynamics simulations. Methods. We used the magnetohydrodynamics code PLUTO in spherical coordinates to reproduce the interaction of the solar wind with the Mercury magnetosphere. First, the optimal wind conditions for the SMS formation were identified with respect to the orientation of the interplanetary magnetic field (IMF) and dynamic pressure. Next, the magnetic field calculated in the simulations along the MESSENGER trajectory was compared to MESSENGER magnetometer data to identify tracers of the satellite encounter with the SMS. Results. Optimal wind conditions for the formation of SMS require that the IMF is oriented in the northward or radial directions. The MESSENGER orbit on 8th September 2011 takes place during wind conditions that are close to the optimal configuration for SMS formation near the north pole, leading to the possible intersection of the satellite trajectory with the SMS. MESSENGER magnetometer data show a rather strong decrease in the magnetic field module after the satellite crossed nearby the compression front that is observed in the simulation, providing indirect evidence of the SMS.
