description: Leveraged and inverse exchange-traded funds seek daily returns equal to fixed multiples of indexes’ returns, but the ensuing rebalancing costs create a tension between a high correlation with the index and a low average deviation from the leveraged index’ performance. With proportional trading costs, we find that the optimal replication policy is robust to the index’ dynamics and obtain a sufficient statistic for index replication performance, the implied spread, which is insensitive to risk-premia and enables comparisons of funds tracking different factors of an index. Overall, the impact of trading costs on replication performance is comparable to or higher than the effect of management fees
title: A Systems Theory-Based Framework for Environmental Scanning in Complex System Governance
Creators: name: Baugh, Dale E.
Publisher: name: Old Dominion University Libraries
Year: 2022

description: he purpose of this research was to develop a Systems Theory-based framework for Environmental Scanning (ES) in Complex System Governance (CSG) using an inductive research design. Complexity and uncertainty are normal for external environments in which today’s systems (organizations) exist. These environmental characteristics provide impetus for researchers to focus on organizational planning for disruptive external forces that could threaten system stability and future system existence. The ES function supports the requisite governance metasystemic functions to be enabled, executed, and evolved sufficiently well to promote continuous system viability. In this research the functioning of ES was examined from a diverse literature-based perspective. The literature acknowledges the importance of the ES function, but its consistent development and its impact on system viability in a turbulent environment is not well developed from a Systems Theory-based perspective. This gap in knowledge was addressed in this research.

This research examined metasystemic functions performed by ES across a broad literature base encompassing Systems Theory, CSG, Managerial Cybernetics, and ES from several fields of study. This research focused on the lack of explicit use of Systems Theory in ES functionality in metasystemic governance. This research presents a theoretical construct for the expansion of the functionality of ES in CSG that supports enhanced system viability.

A rigorous research approach employing a constructivist Grounded Theory Method (GTM) was used to analyze the qualified research literature with a focus on Systems Theory to both consolidate and expand the known functionality of ES in CSG. This research provided a theoretical seventeen-function Systems Theory-based framework for ES in CSG. The overarching theory from this framework is that ES functions support complex system viability through regulation of internal and external variety that is induced by external changes. The literature-based identification of the ES functions demonstrates that ES operates in newly identified mechanisms, beyond the original identification provided by Keating & Katina (2016). A case study was undertaken to demonstrate face validation of the applicability of the emerging Systems Theory-based functions of ES in CSG in an applied setting where possible utility was developed.

Topics for future research in ES functionality were identified.

description: Topological crystalline insulators (TCIs) are insulating materials whose topological property relies on generic crystalline symmetries. Based on first-principles calculations, we study a three-dimensional (3D) crystal constructed by stacking two-dimensional TCI layers. Depending on the inter-layer interaction, the layered crystal can realize diverse 3D topological phases characterized by two mirror Chern numbers (MCNs) ($μ_1,μ_2$) defined on inequivalent mirror-invariant planes in the Brillouin zone. As an example, we demonstrate that new TCI phases can be realized in layered materials such as a PbSe (001) monolayer/h-BN heterostructure and can be tuned by mechanical strain. Our results shed light on the role of the MCNs on inequivalent mirror-symmetric planes in reciprocal space and open new possibilities for finding new topological materials.

description: Modern commercial aircraft can experience significant solar loading during turnaround when the aircraft is stationary on the tarmac. With the increased usage of composite materials, a change in the aircraft thermal environment results due to the substantial difference in metal and composite thermal properties. In this paper, an experimental study is undertaken to compare the thermal environment established in a CFRP and aluminium wingbox compartment due to solar loading for levels of 81 W/m2 , 396 W/m2 , 700 W/m2 and two further cases with a constant wing skin temperature of 100 ◦C. It was found that conduction through the vertical front and rear spars established a complex but stable flow environment comprising of four counter-rotating circulations which interact strongly with the spar walls, a criterion using scale analysis was also established to determine whether the induced flow would persist. Nusselt number measurements were carried out for each circulation and compared to existing correlations from the literature for differentially heated and top wall heated cavities. The measurements provide aircraft thermal designers with representative values for the heat transfer coefficient which can be used in the thermal modeling of aircraft wing structures.

description: We propose rotation inferred from the polar decomposition of the flow gradient as a diagnostic for elliptic (or vortex-type) invariant regions in non-autonomous dynamical systems. We consider here two- and three-dimensional systems, in which polar rotation can be characterized by a single angle. For this polar rotation angle (PRA), we derive explicit formulas using the singular values and vectors of the flow gradient. We find that closed level sets of the PRA reveal elliptic islands in great detail, and singular level sets of the PRA uncover centers of such islands. Both features turn out to be objective (frame-invariant) for two-dimensional systems. We illustrate the diagnostic power of PRA for elliptic structures on several examples.

Does a cryptic pocket exist within the E. faecalis SAM-III riboswitch?
Creators: name: Story, Jarett
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 2021

description: Riboswitches are a broad class of RNA cis regulatory elements that enable controlled regulation of both mRNA transcription and translation. In E. faecalis, the SAM-III riboswitch responds to concentrations of S-adenosyl methionine (SAM) in order to regulate translation of the metK gene product, SAM synthetase. Following structural identification of a cryptic pocket in this structure, a fluorescent RNA assay detected binding of L-homocysteine and several structural analogs to this riboswitch. The binding responses of these ligands indicate they bind in a pocket distinct from the known SAM binding pocket. If further research can identify specific binding interactions that occur in the cryptic pocket, then the SAM-III riboswitch of E. faecalis will be the first example of a riboswitch capable of dual allosteric regulation at two distinct sites.

description: We present a method that can simultaneously locate positions of overlapped multi-emitters at the theoretical-limit precision. We derive a set of simple equations whose solution gives the maximum likelihood estimator of multi-emitter positions. We compare the performance of our simultaneous localization analysis with the conventional single-molecule analysis for simulated images and show that our method can improve the time-resolution of superresolution microscopy an order of magnitude. In particular, we derive the information-theoretical bound on time resolution of localization-based superresolution microscopy and demonstrate that the bound can be closely attained by our analysis.

description: The final assembly of terrestrial planets occurs via massive collisions, which can launch copious clouds of dust that are warmed by the star and glow in the infrared. We report the real-time detection of a debris-producing impact in the terrestrial planet zone around a 35-million year-old solar analog star. We observed a substantial brightening of the debris disk at 3-5 μm, followed by a decay over a year, with quasi-periodic modulations of the disk flux. The behavior is consistent with the occurrence of a violent impact that produced vapor out of which a thick cloud of silicate spherules condensed that were ground into dust by collisions. These results demonstrate how the time domain can become a new dimension for the study of terrestrial planet formation.

description: El presente capítulo muestra cómo la psicología crítica exige cierta sensibilidad ante el aspecto estructural de la violencia para poder cuestionar la forma en que tal aspecto se ve disimulado, soslayado y psicologizado en la investigación psicológica dominante. Lo que aquí se pone de manifiesto, en otras palabras, es que la autocrítica de la psicología implica necesariamente una crítica de la estructura cultural, económica, social y política en la que se genera la violencia y en la que se inserta la misma disciplina psicológica. Esto habrá de ilustrarse a través del caso particular de México, en donde la psicología de la violencia, intentando explicar expresiones individuales de la espiral violenta que se vive en el país, tiende a ocultar sistemáticamente diversas formas de violencia estructural como la desigualdad, la discriminación y la explotación, el racismo y la miseria.

Natural Variability in clv2 Phenotypes
Creators: name: VanDerMolen, Kylie
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 2021

description: Plants develop continually throughout their lifetime from central regions of growth, called meristems, that contain dividing cells that will either differentiate to form organs or remain undifferentiated in what is called the stem cell niche. Maintenance of this stem cell niche by signaling molecules is necessary for proper development, as this niche allows for new organs to be made over the course of the plant’s life. The CLAVATA2 (CLV2) leucine-rich repeat receptor-like protein inhibits stem cell proliferation in the shoot meristem. Mutations in clv2 lead to an overproduction of stem cells, resulting in increased organ number. Additionally, clv2 mutants in the Arabidopsis thaliana Columbia (Col-0) ecotype have a secondary phenotype with disruption in production of flowers, but this effect is not seen in the Landsberg-erecta (Ler-0) ecotype. The cause of this phenotypic variation is unknown. Here, we analyze the genetic basis of this phenotypic discrepancy using mapping-by-sequencing supplemented with fine marker mapping to identify regions of the genome linked to CLV2-mediated ¬flower development. We determined the nature of this genetic relationship to be a semi-dominant, multigenic interaction and identified a 150 Kb region of chromosome 5 that is linked to the clv2 terminating flower phenotype seen in Col-0. To further investigate this phenotype, we used CRISPR-Cas9 in 17 additional genetically and geographically diverse Arabidopsis ecotypes to mutate clv2. Comparing clv2 phenotypes across ecotypes could reveal how flower development is linked with adaptations in local environments. This genetic link provides insight into how floral signaling is robustly maintained across geographically divergent environments, and has potential implications with regards to crop production in Earth’s changing climate.

Here, p-type Cu2O and n-type ZnO were used as positive and negative electrodes of the electric double-layer capacitor structure. When the gate voltage was applied between two electrodes, the holes and electrons were accumulated on the surface of Cu2O and ZnO, respectively. The thermopower was measured by applying thermal gradient along the accumulated layer on the electrodes. We demonstrate here that the accumulated layers are worked as a p-n pair of the thermoelectric device.

description: Within the last two decades, coronaviruses have generated devastating effects on humans being. Especially in 2020, the appearance of new coronaviruses, COVID-19, makes researchers aware of the importance of forecasting and predicting the COIVD-19 spreading patterns. This research utilizes four different time series models - Naïve model, ARIMA model, Horizon-Specific Model without Difference, and Horizon-Specific Model with Difference – to predict the case and death rate with a horizon time of 1 day, 3 days, and 5 days ahead for 173 different countries. We identify the best model for each country based on the minimization of out-of-sample root mean squared error (RMSE). The results show that when forecasting the case rate, ARIMA models are the best fit for around 54% of countries with a horizon time of 1 day ahead, while the horizon-specific models without difference are the most appropriate for about 50% and 49% of countries with a horizon time of 3 days and 5 days ahead, respectively. When forecasting the death rate, the ARIMA models significantly outperform the others and are suitable for 59%, 39%, and 40% of countries with a horizon of 1 day, 3 days, and 5 days ahead, respectively.
Collegiate Barriers to Success in First-Generation and LatinX College Students

description: First-generation and LatinX representation in higher education has been increasing since the early 2000's, however, these students face a number of financial, social, academic, and health related barriers to collegiate success unique to their demographic. The dominant literature suggests that first-generation and latinx students are at higher risk for imposter syndrome, debt aversion, and mental health stigma. My ANOVA and T-test models found that first-generation college students were more likely to experience mental health stigma, imposter syndrome, and debt aversion while latinx students were more likely to experience mental health stigma and debt aversion. Contrary to intuition, income was not the driving factor for debt aversion or imposter syndrome, implying both are culturally rather than financially motivated.

description: The paper provides insights into the mental health consequences of the coronavirus disease 2019 (COVID-19) pandemic from the Central, Eastern, Nordic, Southern, and Western subregions of Europe, represented by five member countries of the European Society for Traumatic Stress Studies (ESTSS). On the basis of the existing national research and experiences in these countries, we propose five lessons learned. (1) There is no evidence of a mental health pandemic so far in the countries in focus. No increase in severe mental disorders but some increase in the symptoms of common mental health disorders are observable. More high-quality longitudinal studies are needed to understand the mental health burden of the pandemic. (2) The pandemic affects countries (including the mental health situation) differently, depending on the level of the exposure, management policies, pre-pandemic structural characteristics, and healthcare resources. (3) The pandemic affects people differently: the exposure severity to pandemic-related stressors differs between individuals, as well as individual resources to cope with these stressors. There are winners and losers as well as identifiable at-risk groups that need particular attention. (4) Besides the negative consequences, the pandemic has had a positive impact. The rapidly applied innovations within the system of healthcare responses provide a window of opportunity for positive changes in mental healthcare policies, strategies, and practices. The increased focus on mental health during the pandemic may contribute to the prioritization of mental health issues at policy-making and organizational levels and may reduce stigma. (5) A stress- and trauma-informed response to COVID-19 is required. The European community of psychotraumatologists under the leadership of ESTSS plays an important role in promoting stress- and trauma-informed healthcare and policies of pandemic management. Based on the lessons learned, we propose a stepped-care public mental health model for the prevention of adverse mental health outcomes during pandemics. Population mental health is affected differently in the COVID-19 pandemic: there are winners and losers, as well as identifiable at-risk groups that need particular attention.A stress- and trauma-informed public mental health stepped-care model can address pandemic-related mental health burden in a systematic way.

description: Although the (varying power)-law modified gravity toy model has the attractive feature of unifying the early and late-time expansions of the Universe, thanks to the peculiar dependence of the scalar field's potential on the scalar curvature, the model still suffers from the fine-tuning problem when used to explain the actually observed Hubble parameter. Indeed, a more correct estimate of the mass of the scalar field needed to comply with actual observations gives an unnaturally small value. On the other hand, for a massless scalar field the potential would have no minimum and hence the field would always remain massless. What solves these issues are the radiative corrections that modify the field's effective potential. These corrections raise the field's effective mass rendering the model free from fine-tuning, immune against positive fifth-force tests, and better suited to tackle the dark matter sector.

description: Some cells have to take decision based on the quality of surroundings ligands, almost irrespective of their quantity, a problem we name "absolute discrimination". An example of absolute discrimination is recognition of not-self by immune T Cells. We show how the problem of absolute discrimination can be solved by a process called "adaptive sorting". We review several implementations of adaptive sorting, as well as its generic properties such as antagonism. We show how kinetic proofreading with negative feedback implements an approximate version of adaptive sorting in the immune context. Finally, we revisit the decision problem at the cell population level, showing how phenotypic variability and feedbacks between population and single cells are crucial for proper decision.

description: Disasters can have long-lasting impacts on mental health. Intrusive memories have been found to be common and persistent in the aftermath of earthquakes. To explore, using diaries, intrusive memories’ presence, content, characteristics, and relationship with probable post-traumatic stress disorder (PTSD) in a small rural community exposed to mass destruction and loss of life. Survivors of the 2016–2017 Central Italy earthquakes (N = 104) were first interviewed to investigate the presence of intrusive memories of the disaster. Those that reported intrusive memories were subsequently asked to complete a 7-day paper-and-pen diary tracking their spontaneous memories of the earthquake events. Twenty months after the earthquakes, 49% (n = 51) of the sample reported having experienced intrusive memories post-earthquake and 38% (n = 39) reported at least one intrusive memory in their diaries. Memories were rated as being distressing, vivid, and experienced as a mixture of images and thoughts. The content of intrusive memories generally focused on sensations and experiences during the earthquake. Other common categories of content were the material environment and physical objects as well as human loss & death. Several memories had a social focus. A minority of memories contained more positive content as well as content from before and after the earthquake. Some participants (28%) experienced repeated intrusive memories of the same content. Memories of participants with and without probable PTSD did not significantly differ on characteristics or content. Intrusive memories can be common, distressing, and persistent occurrences following disasters, even in survivors not suffering from probable PTSD. Intrusive memories were common, distressing, and vivid more than 1-year post-disaster.They captured peri-earthquake sensations, material destruction, death, and social interactions.No difference in content or characteristics was found between participants with and without probable PTSD.

description: The tropical West Pacific hosts the warmest part of the surface ocean and has a considerable impact on the global climate system. Reconstructions of past temperature in this region can elucidate climate connections between the tropics and poles and the sensitivity of tropical temperature to greenhouse forcing. However, existing data are equivocal and reliable information from terrestrial archives is particularly sparse. Here we constrain the magnitude and timing of land temperature change in the tropical West Pacific across the last deglaciation using an exceptionally precise paleothermometer applied to a well-dated stalagmite from Northern Borneo. We show that the cave temperature increased by 4.4 ± 0.3 °C (2 SEM) from the Last Glacial Maximum to the Holocene, amounting to 3.6 ± 0.3 °C (2 SEM) when correcting for sea-level induced cave altitude change. The warming closely follows atmospheric CO2 and Southern Hemisphere warming. This contrasts with hydroclimate, as reflected by drip water δ18O, which responds to Northern Hemisphere cooling events in the form of prominent drying, while temperature was rising. Our results thus show a close response of tropical temperature to greenhouse forcing, independent of shifts in the tropical circulation patterns.

description: We present results from multiwavelength observations of the galaxy NGC5005. We use new neutral hydrogen (HI) observations from the Very Large Array to examine the neutral gas morphology and kinematics. We find an HI disk with a well-behaved flat rotation curve in the radial range 20\arcsec-140\arcsec. Ionized gas observations from the SparsePak integral field unit on the WIYN 3.5m telescope provide kinematics for the central 70\arcsec. We use both the SparsePak and HI velocity fields to derive a rotation curve for NGC5005. Deep 3.6μm observations from the Spitzer Space Telescope probe the faint extended stellar population of NGC5005. The images reveal a large stellar disk with a high surface brightness component that transitions to a low surface brightness component at a radius nearly 1.6 times farther than the extent of the gas disk detected in HI. The 3.6μm image is also decomposed into bulge and disk components to account for the stellar light distribution. Optical broadband B and R and narrowband Hα from the WIYN 0.9m telescope complement the 3.6μm data by providing information about the dominant stellar population and current star formation activity. The neutral and ionized gas rotation curve is used along with the stellar bulge and disk light profiles to decompose the mass distributions in NGC5005 and determine a dark matter halo model. The maximum stellar disk contribution to the total rotation curve is only about 70\%, suggesting that dark matter makes a significant contribution to the dynamics at all radii.

description: The covariance matrix of a $p$-dimensional random variable is a fundamental quantity in data analysis. Given $n$ i.i.d. observations, it is typically estimated by the sample covariance matrix, at a computational cost of $O(np^{2})$ operations. When $n,p$ are large, this computation may be prohibitively slow. Moreover, in several contemporary applications, the population matrix is approximately sparse, and only its few large entries are of interest. This raises the following question, at the focus of our work: Assuming approximate sparsity of the covariance matrix, can its large entries be detected much faster, say in sub-quadratic time, without explicitly computing all its $p^{2}$ entries? In this paper, we present and theoretically analyze two randomized algorithms that detect the large entries of an approximately sparse sample covariance matrix using only $O(np\text{ poly log } p)$ operations. Furthermore, assuming sparsity of the population matrix, we derive sufficient conditions on the underlying random variable and on the number of samples $n$, for the sample covariance matrix to satisfy our approximate sparsity requirements. Finally, we illustrate the performance of our algorithms via several simulations.
