description: The Galactic centre is a bright gamma-ray source with the GeV-TeV band spectrum composed of two distinct components in the 1-10 GeV and 1-10 TeV energy ranges. The nature of these two components is not clearly understood. We investigate the gamma-ray properties of the Galactic centre to clarify the origin of the observed emission. We report imaging, spectral, and timing analysis of data from 74 months of observations of the Galactic centre by FERMI/LAT gamma-ray telescope complemented by sub-MeV data from approximately ten years of INTEGRAL/PICsIT observations. We find that the Galactic centre is spatially consistent with the point source in the GeV band. The tightest 3 sigma upper limit on its radius is 0.13 degree in the 10-300 GeV energy band. The spectrum of the source in the 100 MeV energy range does not have a characteristic turnover that would point to the pion decay origin of the signal. Instead, the source spectrum is consistent with a model of inverse Compton scattering by high-energy electrons. In this a model, the GeV bump in the spectrum originates from an episode of injection of high-energy particles, which happened ~300 years ago. This injection episode coincides with the known activity episode of the Galactic centre region, previously identified using X-ray observations. The hadronic model of source activity could be still compatible with the data if bremsstrahlung emission from high-energy electrons was present in addition to pion decay emission.

description: Active Simultaneous Localization and Mapping (SLAM) is the problem of planning and controlling the motion of a robot to build the most accurate and complete model of the surrounding environment. Since the first foundational work in active perception appeared, more than three decades ago, this field has received increasing attention across different scientific communities. This has brought about many different approaches and formulations, and makes a review of the current trends necessary and extremely valuable for both new and experienced researchers. In this work, we survey the state-of-the-art in active SLAM and take an in-depth look at the open challenges that still require attention to meet the needs of modern applications. After providing a historical perspective, we present a unified problem formulation and review the well-established modular solution scheme, which decouples the problem into three stages that identify, select, and execute potential navigation actions. We then analyze alternative approaches, including belief-space planning and deep reinforcement learning techniques, and review related work on multi-robot coordination. The manuscript concludes with a discussion of new research directions, addressing reproducible research, active spatial perception, and practical applications, among other topics.

description: Study Objectives: Inter-scorer variability in scoring polysomnograms is a well-known problem. Most of the existing automated sleep scoring systems are trained using labels annotated by a single scorer, whose subjective evaluation is transferred to the model. When annotations from two or more scorers are available, the scoring models are usually trained on the scorer consensus. The averaged scorer's subjectivity is transferred into the model, losing information about the internal variability among different scorers. In this study, we aim to insert the multiple-knowledge of the different physicians into the training procedure. The goal is to optimize a model training, exploiting the full information that can be extracted from the consensus of a group of scorers. Methods: We train two lightweight deep learning based models on three different multi-scored databases. We exploit the label smoothing technique together with a soft-consensus (LSSC) distribution to insert the multiple-knowledge in the training procedure of the model. We introduce the averaged cosine similarity metric (ACS) to quantify the similarity between the hypnodensity-graph generated by the models with-LSSC and the hypnodensity-graph generated by the scorer consensus. Results: The performance of the models improves on all the databases when we train the models with our LSSC. We found an increase in ACS (up to 6.4%) between the hypnodensity-graph generated by the models trained with-LSSC and the hypnodensity-graph generated by the consensus. Conclusion: Our approach definitely enables a model to better adapt to the consensus of the group of scorers. Future work will focus on further investigations on different scoring architectures and hopefully large-scale-heterogeneous multi-scored datasets.

Subjects: Doula care

description: The purpose of this paper is to identify priority counties for North Carolina to introduce community-based doula care programs based on current maternal health outcomes and social determinants of health. Rural counties were expected to be the top priority areas to introduce doula care programs. To determine priority areas, we created a scoring system and used linear least squares regression models and beta weights to determine how many points to assign each proposed component of the scoring system. Once the scoring system was created, we scored each county based on how well they performed for each maternal health or social determinant of health indicator. The findings indicated that rural counties would benefit the most from expansion of doula care services.

description: In the Galaxy, extremely large mass-ratio inspirals(X-MRIs) composed of brown dwarfs and the massive black hole at the Galactic Center are expected to be promising gravitational wave sources for space-borne detectors. In this work, we simulate the gravitational wave signals from twenty X-MRI systems by an axisymmetric Konoplya-Rezzolla-Zhidenko metric with varied parameters. We find that the mass, spin, and deviation parameters of the Kerr black hole could be determined accurately ( $\sim 10^{-5} - 10^{-6}$ ) with only one X-MRI event with a high signal-to-noise ratio. The measurement of the above parameters could be improved with more X-MRI observations.

Assessing the potential for retrofitting a North Durham strip mall: An effort to increase safety and sustainability in the Bull City
Creators: name: Heffernan, Ellen
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 2022

description: This undergraduate thesis evaluates the potential for retrofitting in one Durham strip mall parcel, Riverview Shopping Center. Using Jan Gehl's approach to public space and Emily Talen's framework for selecting viable retrofitting candidates, this project builds on existing research about sprawl and retrofitting. This thesis begins by summarizing existing literature on the history of suburbs, the threats sprawl poses to the environment and human health, and techniques that have been used to successfully retrofit suburban areas. This thesis provides photographic evidence of design flaws at Riverview Shopping Center that prevent the growth of public life and non-vehicular transportation. Data was also collected to create several pedestrian activity maps to explore the scope of public life at the shopping center.

description: We investigate neutron star solutions in scalar-tensor theories of gravity with first-order derivative self-interactions in the action and in the matter coupling. We assess the robustness of the kinetic screening mechanism present in these theories against general conformal couplings to matter. The latter include ones leading to the classical Damour-Esposito-Farèse scalarization, as well as ones depending on the kinetic term of the scalar field. We find that kinetic screening always prevails over scalarization, and that kinetic couplings with matter enhance the suppression of scalar gradients inside the star even more, without relying on the non-linear regime. Fine tuning the kinetic coupling with the derivative self-interactions in the action allows one to partially cancel the latter, resulting in a weakening of kinetic screening inside the star. This effect represents a novel way to break screening mechanisms inside matter sources, and provides new signatures that might be testable with astrophysical observations.

The powder diffraction study of a crushed crystal fragment does not reveal any structural change down to 4 K. The muSR measurements performed at 20 mK on a mosaic of single crystals with an external magnetic field applied along a three-fold axis are consistent with published a.c. magnetic-susceptibility measurements at 16 mK. While an inflection point could be present around an internal field intensity slightly above 0.3 T, the data barely support the presence of a magnetization plateau.

WHEN “BEST” IS NOT ENOUGH: The Underrepresentation of Latinx Students in Gifted Education Programs in “Best Practice” North Carolina Public School Districts
Creators: name: Melanie Godinez-Cedillo
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 2022

description: This thesis evaluates the underlying reasons behind the vast underrepresentation of Latinx students in gifted education programs in North Carolina’s public schools.  Specifically, this thesis analyzes Montgomery County and Johnston County, which are both deemed “best practice” by the North Carolina Department of Public Instruction but showcase different rates of Latinx representation within their gifted programs. Using a mixed-methods approach, this thesis explores how the current initiatives outlined in the gifted education plans of each local education agency (LEA) impact the representation of Latinx students found within each LEA. The findings in this thesis demonstrate the complex nuances, both in and outside the traditional classroom, that generate disparities in student representation with gifted education. The findings of this research discuss the identifies gaps in intended policy outlined in each district’s gifted education plans, questioning how the North Carolina Department of Public Instruction deems best practice counties, debates the meaning of “equitable” representation in gifted education programs, and comments on the results of the implementation (or lack of) of these initiatives. Given that the current literature on gifted Latinx students in North Carolina is limited, this thesis serves as a first look at the various factors that drive inequity and suppress the identification of talented Latinx students in the state. Ultimately, this research underscores the need to better understand the unique needs of Latinx students including but not limited to 1) language barriers 2) the impact of socioeconomic status 3) Latinx family involvement 4) merit of current implemented initiatives and 5) the shortcomings of current equity-based initiatives.

description: Credit estimation and bankruptcy prediction methods have been utilizing Altman's $z$ score method for the last several years. It is reported in many studies that $z$ score is sensitive to changes in accounting figures. Researches have proposed different variations to conventional $z$ score that can improve the prediction accuracy. In this paper we develop a new multivariate non-linear model for computing the $z$ score. In addition we develop a new credit risk index by fitting a Pearson type-III distribution to the transformed financial ratios. The results from our study have shown that the new $z$ score can predict the bankruptcy with an accuracy of $98.6\%$ as compared to $93.5\%$ by the Altman's $z$ score. Also, the discriminate analysis revealed that the new transformed financial ratios could predict the bankruptcy probability with an accuracy of $93.0\%$ as compared to $87.4\%$ using the weights of Altman's $z$ score.

В связи с нехваткой собственных трудовых ресурсов многие государства (в том числе и Россия) разрабатывают максимально эффективные механизмы привлечения, отбора и учета иностранных мигрантов, которые могли бы поспособствовать экономическому и демографическому развитию страны. В данной статье представлен анализ концепций государственной миграционной политики РФ на периоды 2012-2025 и 2019-2025 гг. Приводится сравнительная характеристика этих концепций, а также озвучиваются потенциальные проблемы миграционного развития РФ в ближайшем будущем.One of the most important conditions for the effective economic development is its sufficient supply of human capital. Due to the lack of their own labor resources, many states (including Russia) are developing the most effective mechanisms for attracting, selecting and registering foreign migrants, which could contribute to the economic and demographic development of the country. This article presents an analysis of the concepts of the state migration policy of the Russian Federation for the periods 2012-2025 and 2019-2025. A comparative description of these concepts is given, as well as potential problems of the migration development of the Russian Federation in the near future are voiced.

description: Once main-sequence (MS) solar-like stars transitioned from the saturated to the unsaturated regime in magnetic activity, their evolution was perceived as monotonic, with rotation rate and activity gradually decaying. However, Kepler revolutionized this perspective, showing that the unsaturated regime splits into different regimes. One transition, causing a stalling in the MS spin down, is attributed to core-envelope coupling and the consequent angular momentum transfer between a fast core and a slow envelope. In this work, we find evidence of this transition in the magnetic activity of the full Kepler MS sample and NGC 6811. We investigate the magnetic activity evolution in the Kepler MS sample by computing activity sequences according to the relative rotation. We find the sequences clustering at two distinct regions: 1) at high activity levels coinciding with stars near the transition above, where a behavior inversion is observed; and 2) at low activity levels corresponding to slow rotators close to the detection limit potentially facing a weakening of the magnetic braking. Focusing on NGC 6811, we find evidence for enhanced magnetic activity, that remains for significant timescales, in stars that have already transitioned. These results support the recent proposition that the strong shear encountered during the core-envelope coupling phase can cause enhanced activity. This study will help shed light on the interplay between rotation, magnetic activity, and their evolution.

description: The contextual subspace variational quantum eigensolver (CS-VQE) is a hybrid quantum-classical algorithm that approximates the ground-state energy of a given qubit Hamiltonian. It achieves this by separating the Hamiltonian into contextual and noncontextual parts. The ground-state energy is approximated by classically solving the noncontextual problem, followed by solving the contextual problem using VQE, constrained by the noncontextual solution. In general, computation of the contextual correction needs fewer qubits and measurements compared with solving the full Hamiltonian via traditional VQE. We simulate CS-VQE on different tapered molecular Hamiltonians and apply the unitary partitioning measurement reduction strategy to further reduce the number of measurements required to obtain the contextual correction. Our results indicate that CS-VQE combined with measurement reduction is a promising approach to allow feasible eigenvalue computations on noisy intermediate-scale quantum devices. We also provide a modification to the CS-VQE algorithm; the CS-VQE algorithm previously could cause an exponential increase in Hamiltonian terms, but with this modification now at worst will scale quadratically.

description: Experiments searching for weak interacting massive particles with noble gases such as liquid argon require very low detection thresholds for nuclear recoils. A determination of the scintillation efficiency is crucial to quantify the response of the detector at low energy. We report the results obtained with a small liquid argon cell using a monoenergetic neutron beam produced by a deuterium-deuterium fusion source. The light yield relative to electrons was measured for six argon recoil energies between 11 and 120 keV at zero electric drift field.

description: The census of heavy elements (metals) produced by all stars through cosmic times up to present-day is limited to ~50%; of these only half are still found within their parent galaxy. The majority of metals is expelled from galaxies into the circumgalactic (or even more distant, intergalactic) space by powerful galactic winds, leaving unpleasant uncertainty on the amount, thermal properties and distribution of these key chemical species. These dispersed metals unavoidably absorb soft X-ray photons from distant sources. We show that their integrated contribution can be detected in the form of increasing X-ray absorption with distance, for all kinds of high-energy cosmic sources. Based on extensive cosmological simulations, we assess that $\sim$ 10\% of all cosmic metals reside in the intergalactic medium. Most of the X-ray absorption arises instead from a few discrete structures along the line of sight. These extended structures, possibly pin-pointing galaxy groups, contain million degree, metal-enriched gas, 100-1,000 times denser than the cosmic mean. An additional ~10% of cosmic metals could reside in this phase.

description: В настоящее время на рынок постоянно внедряют новые технологии, программы и другие инновации. Именно поэтому инвестирование в стартапы является актуальным способом наращивания капитала. В данной работе были рассмотрены все положительные и отрицательные стороны инвестирования в стартапы, а также современное положение и развитие инвестирования в данную сферу в России. В стране данный сектор инвестирования недостаточно развит, что подтверждает преимущественная доля государства в структуре инвесторов. В результате исследования были предложены мероприятия, нацеленные на привлечение дополнительных средств, принадлежащим частным и иностранным инвесторам.Currently, new technologies, programs and other innovations are constantly being introduced to the market. That is why investing in startups is an actual way to build capital. In this paper, we examined all the positive and negative aspects of investing in startups, as well as the current situation and development of investing in this area in Russia. In the country, this investment sector is underdeveloped, which confirms the predominant share of the state in the structure of investors. As a result of the study, measures aimed at attracting additional funds belonging to private and foreign investors were proposed.

description: Purpose: Research into epileptic networks has recently allowed deeper insights into the epileptic process. Here we investigated the importance of individual network nodes for seizure dynamics. Methods: We analysed intracranial electroencephalographic recordings of 86 focal seizures with different anatomical onset locations. With time-resolved correlation analyses, we derived a sequence of weighted epileptic networks spanning the pre-ictal, ictal, and post-ictal period, and each recording site represents a network node. We assessed node importance with commonly used centrality indices that take into account different network properties. Results: A high variability of temporal evolution of node importance was observed, both intra- and interindividually. Nevertheless, nodes near and far off the seizure onset zone (SOZ) were rated as most important for seizure dynamics more often (65% of cases) than nodes from within the SOZ (35% of cases). Conclusion: Our findings underline the high relevance of brain outside of the SOZ but within the large-scale epileptic network for seizure dynamics. Knowledge about these network constituents may elucidate targets for individualised therapeutic interventions that aim at preventing seizure generation and spread.

description: We introduce the Symplectic Grassmann codes as projective codes defined by symplectic Grassmannians, in analogy with the orthogonal Grassmann codes introduced in [4]. Note that the Lagrangian-Grassmannian codes are a special class of Symplectic Grassmann codes. We describe the weight enumerator of the Lagrangian--Grassmannian codes of rank $2$ and $3$ and we determine the minimum distance of the line Symplectic Grassmann codes.
