description: Using data from the all-sky Wide-Field Infrared Survey Explorer (WISE) satellite, we made a catalog of over 8000 Galactic HII regions and HII region candidates by searching for their characteristic mid-infrared (MIR) morphology. WISE has sufficient sensitivity to detect the MIR emission from HII regions located anywhere in the Galactic disk. We believe this is the most complete catalog yet of regions forming massive stars in the Milky Way. Of the ~8000 cataloged sources, ~1500 have measured radio recombination line (RRL) or H$α$ emission, and are thus known to be HII regions. This sample improves on previous efforts by resolving HII region complexes into multiple sources and by removing duplicate entries. There are ~2500 candidate HII regions in the catalog that are spatially coincident with radio continuum emission. Our group's previous RRL studies show that ~95% of such targets are HII regions. We find that ~500 of these candidates are also positionally associated with known HII region complexes, so the probability of their being bona fide HII regions is even higher. At the sensitivity limits of existing surveys, ~4000 catalog sources show no radio continuum emission. Using data from the literature, we find distances for ~1500 catalog sources, and molecular velocities for ~1500 HII region candidates.

description: Superlattices consist of two ferromagnets La0.7Sr0.3MnO3(LSMO)and SrRuO3(SRO) were grown in (110)-orientation on SrTiO3(STO) substrates. The x-ray diffraction and Raman spectra of these superlattices show the presence of in-plane compressive strain and orthorhombic structure of less than 4 u.c. thick LSMO spacer,respectively. Magnetic measurements reveal several features including reduced magnetization, enhanced coercivity, antiferromagnetic coupling, and switching from antiferromagnetic to ferromagnetic coupling with magnetic field orientations. These magnetic properties are explained by the observed orthorhombic structure of spacer LSMO in Raman scattering which occurs due to the modification in the stereochemistry of Mn at the interfaces of SRO and LSMO.

 The grammar and acquisition of Sanna (Cypriot Maronite Arabic) across generations Natalia Pavlou
 University of Cyprus, Cyprus Acquisition Team Abstract: The phenomenon of unbalanced bilingualism found in speakers with a heritage acquisition profile has led researchers to conduct theoretical, experimental, and applied studies to investigate populations that use a dominant language in their community along with a home language, referred to as a heritage language. A large body of existing work has concentrated on the ways in which heritage and baseline grammars differ or exhibit variation, as well as the role of the linguistic data available to a speaker in the acquisition of their L1, the parsing and encoding of that input and any factors that affect its representation (Polinsky & Scontras 2020; Montrul & Polinsky 2021; Polinsky 2018). In this work, I focus on Sanna (Cypriot Maronite Arabic), which is an endangered language found on the island of Cyprus. I will discuss its grammar and its contact with the dominant variety of Cypriot Greek, the different speaker groups within this community based on its acquisition as a heritage language, the variation in the competence in speakers of different proficiency and the sociolinguistic factors that describe the community. Based on experimental results, I show that speakers of the community show grammatical divergence from the target language structures, supporting the need for sophisticated heritage language research.
An analytical framework for assessing types of refugee accommodation from a public health perspective

description: Housing is considered an important social determinant of health. In the context of refugee migration, living in one’s own apartment is a key indicator of successful integration. The type of housing in which refugees are accommodated, however, varies widely. Empirically, measuring health-related attributes of accommodation is challenging. The (international) refugee camp context has been focused on from various fields of research, often drawing on particular theoretical concepts. In this article, these theoretical concepts – mainly based on the work of Hannah Arendt, Erving Goffman, Michel Foucault and Giorgio Agamben – form the basis for developing a broad analytical framework of refugee accommodation. Housing in the context of refugee accommodation must be understood from four dimensions, including the broader political context, the immediate surroundings of the accommodation and its’ physical and social boundaries, and the structures and processes inside the accommodation that may establish means of social control. As the conditions on each of these three dimensions can affect individuals differently, a fourth, individual dimension complements this analytical framework by a subjective evaluation of the overall living situation. The framework provides a multidimensional approach to assess the context of refugee accommodation which then can be used to systematically analyse health associations. The relevance the dimensions and contextual factors of this framework have on health is supported by empirical evidence as well as conceptual approaches.

description: This paper re-investigates a lexical acquisition system initially developed for French.We show that, interestingly, the architecture of the system reproduces and implements the main components of Optimality Theory. However, we formulate the hypothesis that some of its limitations are mainly due to a poor representation of the constraints used. Finally, we show how a better representation of the constraints used would yield better results.

description: The total variation (TV) regularization method is an effective method for image deblurring in preserving edges. However, the TV based solutions usually have some staircase effects. In this paper, in order to alleviate the staircase effect, we propose a new model for restoring blurred images with impulse noise. The model consists of an $\ell_1$-fidelity term and a TV with overlapping group sparsity (OGS) regularization term. Moreover, we impose a box constraint to the proposed model for getting more accurate solutions. An efficient and effective algorithm is proposed to solve the model under the framework of the alternating direction method of multipliers (ADMM). We use an inner loop which is nested inside the majorization minimization (MM) iteration for the subproblem of the proposed method. Compared with other methods, numerical results illustrate that the proposed method, can significantly improve the restoration quality, both in avoiding staircase effects and in terms of peak signal-to-noise ratio (PSNR) and relative error (ReE).

description: We present a new complete set of states for a class of open quantum systems, to be used in expansion of the Green's function and the time-evolution operator. A remarkable feature of the complete set is that it observes time-reversal symmetry in the sense that it contains decaying states (resonant states) and growing states (anti-resonant states) parallelly. We can thereby pinpoint the occurrence of the breaking of time-reversal symmetry at the choice of whether we solve Schroedinger equation as an initial-condition problem or a terminal-condition problem. Another feature of the complete set is that in the subspace of the central scattering area of the system, it consists of contributions of all states with point spectra but does not contain any background integrals. In computing the time evolution, we can clearly see contribution of which point spectrum produces which time dependence. In the whole infinite state space, the complete set does contain an integral but it is over unperturbed eigenstates of the environmental area of the system and hence can be calculated analytically. We demonstrate the usefulness of the complete set by computing explicitly the survival probability and the escaping probability as well as the dynamics of wave packets. The origin of each term of matrix elements is clear in our formulation, particularly the exponential decays due to the resonance poles.

description: We present a detailed and self-contained analytical derivation of the evolution of sub-horizon cosmological perturbations before decoupling, based on previous work by S. Weinberg. These solutions are valid in the minimal LCDM scenario, to first order in perturbation theory, in the tight-coupling limit and neglecting neutrino shear stress. We compare them to exact numerical solutions computed by a Boltzmann code, and we find the two to be in very good agreement. The analytic solutions show explicitly that CDM and the baryon-photon fluid effectively behave as separate self-gravitating fluids until the epoch of baryon drag. This in turn leads to the surprising conclusion that the CMB is much less sensitive to the clustering properties of minimally coupled Dark Matter models than what would be naively expected.

description: Digital documentation of large interiors of historical buildings is an exhausting task since most of the areas of interest are beyond typical human reach. We advocate the use of autonomous teams of multi-rotor Unmanned Aerial Vehicles (UAVs) to speed up the documentation process by several orders of magnitude while allowing for a repeatable, accurate, and condition-independent solution capable of precise collision-free operation at great heights. The proposed multi-robot approach allows for performing tasks requiring dynamic scene illumination in large-scale real-world scenarios, a process previously applicable only in small-scale laboratory-like conditions. Extensive experimental analyses range from single-UAV imaging to specialized lighting techniques requiring accurate coordination of multiple UAVs. The system's robustness is demonstrated in more than two hundred autonomous flights in fifteen historical monuments requiring superior safety while lacking access to external localization. This unique experimental campaign, cooperated with restorers and conservators, brought numerous lessons transferable to other safety-critical robotic missions in documentation and inspection tasks.

description: Das vorliegende Working Paper skizziert die Auswirkungen der Corona-Pandemie auf ein partizipatives Forschungsprojekt mit Geflüchteten, das an drei Standorten (Berlin, Hannover und München) in Deutschland durchgeführt wird. Das Projekt EMPOW startete im November 2019 – wenige Monate vor Beginn der ersten Pandemie-Welle. Durch die Pandemie und die damit verbundenen Public-Health-Maßnahmen wurde das Forschungsprojekt erheblich behindert. Der Aufbau von Projektstrukturen wurde erschwert und die Kommunikation empfindlich gestört, was sowohl die gemeinsame Formulierung von Projektzielen als auch die Entwicklung von Forschungsbeziehungen und Vertrauen zwischen den Partner:innen beeinträchtigte. Besonders schwerwiegend waren die sozialen, gesundheitlichen und ökonomischen Folgen der Pandemie für Community-Partner:innen, die in Sammelunterkünften untergebracht waren. Zur genaueren Dokumentation dieser Auswirkungen wurden Fokusgruppen mit Projektbeteiligten durchgeführt und Feldnotizen angefertigt. Insgesamt zeigt die Analyse neben substanziellen Hemmnissen und Problemen, welche die Durchführung des Projekts über zwei Jahre teilweise fast unmöglich machten, auch Flexibilität, Kreativität und Commitment in der forschenden Zusammenarbeit, durch die das Projekt trotz widriger Umstände dennoch realisiert werden konnte.
Phosphorylation of lipin 1 beta phosphatidate phosphatase by casein kinase II
Creators: name: Hennessy, Meagan L.
Publisher: name: No Publisher Supplied
Year: 2018

description: Lipin is a phosphatidate phosphatase enzyme that catalyzes the penultimate step in triacylglycerol synthesis, the conversion of phosphatidic acid to diacylglycerol. By controlling this step, lipin regulates both triacylglycerol and phospholipid synthesis, and it also acts as a transcriptional regulator. It is known that phosphorylation controls the subcellular localization of lipin, and its activity as both a phosphatidate phosphatase and a transcriptional regulator. Multiple phosphorylation sites within lipin have been identified, but the identity of the protein kinases involved is largely unknown. In this work, we sought to identify and characterize kinases that play a role in lipin’s regulation.     Using bioinformatics, we found that lipin 1 beta has a high probability of being phosphorylated by casein kinase II. Using purified lipin 1 beta, we showed that casein kinase II catalyzed the incorporation of the gamma-phosphate of [gamma-32P]ATP into the protein. We then focused on the serine-rich domain of lipin 1 beta, which in lipin 1 beta has been shown to be important in subcellular localization through interaction with 14-3-3 protein. We generated a 22-residue peptide that included 7 putative serine/threonine phosphorylation sites, and found that this peptide was phosphorylated by casein kinase II. Phosphorylation analysis of the peptide with alanine substitutions for the putative sites indicated that Ser-285 and Ser-287 were the targets of the kinase. In full-length lipin 1 beta, the S285A mutation caused a greater degree of phosphorylation, whereas the extent of phosphorylation of the S285A/S287A mutant was about the same as that of the control wild type protein. In phosphopeptide mapping analysis, two phosphopeptides present in the wild type protein were absent in both mutant proteins, but one phosphopeptide present in the mutants was absent in the wild type protein. These observations indicate that the phosphorylation by casein kinase II is complex. This work increases our understanding of the posttranslational modification of lipin 1 beta by phosphorylation.

description: This paper presents a self-contained system for the robust utilization of aerial robots in the autonomous exploration of cave environments to help human explorers, first responders, and speleologists. The proposed system is generally applicable to an arbitrary exploration task within an unknown and unstructured subterranean environment and interconnects crucial robotic subsystems to provide full autonomy of the robots. Such subsystems primarily include mapping, path and trajectory planning, localization, control, and decision making. Due to the diversity, complexity, and structural uncertainty of natural cave environments, the proposed system allows for the possible use of any arbitrary exploration strategy for a single robot, as well as for a cooperating team. A multi-robot cooperation strategy that maximizes the limited flight time of each aerial robot is proposed for exploration and search & rescue scenarios where the homing of all deployed robots back to an initial location is not required The entire system is validated in a comprehensive experimental analysis comprising of hours of flight time in a real-world cave environment, as well as by hundreds of hours within a state-of-the-art virtual testbed that was developed for the DARPA Subterranean Challenge robotic competition. Among others, experimental results include multiple real-world exploration flights traveling over 470 meters on a single battery in a demanding unknown cave environment.

description: There is great interest in hybrid organic-inorganic materials such as metal-organic frameworks (MOFs). The compounds [C(NH$_{2}$)$_{3}$]M(HCOO)$_{3}$, where M=Cu$^{2+}$ or Cr$^{2+}$ are Jahn-Teller (JT) active ions, are MOF with perovskite topology which crystallizes in polar space group Pna2$_{1}$. In inorganic compounds, octahedral tilting and Jahn-Teller structural distortions are usually non-polar distortions. However, in this MOF cooperative interactions between the antiferro-distortive distortions of the framework and the C(NH2)$_{3}$ organic cation via hydrogen bonding breaks the inversion symmetry and induces a ferroelectric polarization.[Angew. Chem. Int. Ed. 50, 5847, 2011] Our ab-initio study supports the picture of an orbital-order-induced ferroelectricity, a rare example of dipolar ordering caused by electronic degrees of freedom. The switching of polarization direction implies the reversal of the weak ferromagnetic component. The microscopic mechanism in this JT-based MOF with ABX$_{3}$ perovskite structure displays a Hybrid Improper Ferroelectric (HIF) state, arising from a trilinear coupling between different structural deformations that comprise tilting, rotations and Jahn-Teller distortions of both the BX$_{3}$ framework and the organic cation at the A sites. Since these distortion modes in perovskite-inorganic compounds usually freeze-in at elevated temperatures, the trilinear coupling in MOF compounds may provide an interesting route towards high-temperature multiferroicity. These results offer an important starting point for tailoring multiferroic properties in this emerging class of materials for various technological applications. In particular, the high tunability of the ferroelectric polarization by means of the modification of the organic A cation has been recently shown[J. Am. Chem. Soc. 135 18126 (2013)]

description: Random Forest (RF) is a powerful ensemble method for classification and regression tasks. It consists of decision trees set. Although, a single tree is well interpretable for human, the ensemble of trees is a black-box model. The popular technique to look inside the RF model is to visualize a RF proximity matrix obtained on data samples with Multidimensional Scaling (MDS) method. Herein, we present a novel method based on Self-Organising Maps (SOM) for revealing intrinsic relationships in data that lay inside the RF used for classification tasks. We propose an algorithm to learn the SOM with the proximity matrix obtained from the RF. The visualization of RF proximity matrix with MDS and SOM is compared. What is more, the SOM learned with the RF proximity matrix has better classification accuracy in comparison to SOM learned with Euclidean distance. Presented approach enables better understanding of the RF and additionally improves accuracy of the SOM.

description: This letter presents a self-contained system for robust deployment of autonomous aerial vehicles in environments without access to global navigation systems and with limited lighting conditions. The proposed system, application-tailored for documentation in dark areas of large historical monuments, uses a unique and reliable aerial platform with a multi-modal lightweight sensory setup to acquire data in human-restricted areas with adverse lighting conditions, especially in areas that are high above the ground. The introduced localization method relies on an easy-to-obtain 3-D point cloud of a historical building, while it copes with a lack of visible light by fusing active laser-based sensors. The approach does not rely on any external localization, or on a preset motion-capture system. This enables fast deployment in the interiors of investigated structures while being computationally undemanding enough to process data online, onboard an MAV equipped with ordinary processing resources. The reliability of the system is analyzed, is quantitatively evaluated on a set of aerial trajectories performed inside a real-world church, and is deployed onto the aerial platform in the position control feedback loop to demonstrate the reliability of the system in the safety-critical application of historical monuments documentation.

Seasonal Changes in Water Quality and Primary Productivity in Doe Valley Lake

description: Abstract:
Primary productivity and water quality were studied in Doe Valley Lake, a 147-hectare impoundment on Doe Run, a spring-fed stream in Meade County, Kentucky, from 13 June 1969 to 31 July 1972. Doe Valley Lake is monomictic during most winter seasons, but it is dimictic during more severe winters because of its morphometry and location on the borderline climatic region for dimictic lakes (37° N latitude). Oxygen depletion in the hypolimnion is severe, and anaerobic conditions usually prevail by late June. A hypolimnetic areal deficit of 0.038 mg/cm2/day was calculated. Supersaturation of oxygen in the epilimnion was common, and metalimnetic maxima exceeded 150 percent saturation in spring and early summer.
Primary productivity ranged from 44 to 1,192 mgC/m2/day and annual rates at Stations I and III were 277 and 255 gC/m2/yr, respectively. Productivity fluctuated considerably at Station I as a result of turbidity, but average daily rates and chlorophyll levels were higher than at Station III. Periodic flooding drastically lowered productivity and phytoplankton standing crops. Negative or low correlations were found between productivity and turbidity, pH, alkalinity, nitrates, and phosphates. The relationship between productivity and standing crop of phytoplankton varied throughout the year but positive correlations were observed on an annual basis. Chlorophyll a levels correlated fairly well with net phytoplankton. Except during summer, nannoplankton contributed more than 50 percent of the total carbon assimilation.
The inflowing stream, Doe Run, contributes valuable quantities of nutrients including carbon, nitrogen, phosphorus, and sulfur that enhance the productivity of the lake. Degradation of allochthonous leaf materials introduces significant amounts of carbohydrates, proteins, and lipids into the lake ecosystem, but inflow patterns characteristic of a spring-fed stream greatly influence the fate and availability of these nutrients.

Laboratory Simulation of Rainfall Erosivity for Gully Formation Study

description: Abstract:
The objective of this study was to develop a rainfall simulator, which imparts to the laboratory rainfall the more important characteristics of natural rainfall such as intensity, drop spectrum, kinetic energy, and momentum at impact, for using in soil erosion research with better results. In developing this simulator the better features of the basic types of earlier simulators, drip and nozzle, have been incorporated into this single design. The simulator developed in this study consists of a number of individual box modules placed in a rectangular pattern to form a single unit. Each module has a grid of capillary holes with cone shaped exits drilled through the bottom plate. The modules were mounted so that their bottom plates form the ceiling of a pressurized room. This provides a hydrostatic pressure differential between the bottom plate and the water surface in each module, such that water will not leak through the holes during the nonoperating state. When pressure pulses are applied to the water surface in each module, water drops are ejected with an initial velocity so that a terminal velocity corresponding to a natural rain drop can be attained without requiring excessive height of fall. The test results indicated that this simulator provides good · simulation of the natural rainfall erosivity.

description: 600V/20A 4H-SiC Schottky barrier diodes (SBD) were fabricated to investigate the effect of key processing steps, especially before and after a formation of Schottky contact, on the electrical performances of SBD and on a long-term reliability. The results show that 4H-SiC SBDs, subjected to a hydrogen-ambient annealing at 470oC for 10min and sacrificial treatment right after ion activation, exhibited low forward voltage drop (VF) at a rated current of 20A, higher blocking voltage of 800V, and very short reverse recovery time of 17.5ns. Despite a harsh reverse bias condition and temperature, a long-term reliability test shows that changes in forward voltage drop and reverse leakage current (IR) were 0.7% and 8.9% and that blocking voltage was enhanced. This is attributed to a stabilized interface between passivation layer and SiC that is caused by aging.

description: The assessment of sewer pipe systems is a highly important, but at the same time cumbersome and error-prone task. We introduce an innovative system based on single-shot structured light modules that facilitates the detection and classification of spatial defects like jutting intrusions, spallings, or misaligned joints. This system creates highly accurate 3D measurements with sub-millimeter resolution of pipe surfaces and fuses them into a holistic 3D model. The benefit of such a holistic 3D model is twofold: on the one hand, it facilitates the accurate manual sewer pipe assessment, on the other, it simplifies the detection of defects in downstream automatic systems as it endows the input with highly accurate depth information. In this work, we provide an extensive overview of the system and give valuable insights into our design choices.

description: Biometrics authentication is an effective method for automatically recognizing individuals. The authentication consists of an enrollment phase and an identification or verification phase. In the stages of enrollment known (training) samples after the pre-processing stage are used for suitable feature extraction to generate the template database. In the verification stage, the test sample is similarly pre processed and subjected to feature extraction modules, and then it is matched with the training feature templates to decide whether it is a genuine or not. This paper presents use of a region of interest (ROI) for palm print technology. First some of the existing methods for palm print identification have been introduced. Then focus has been given on extraction of a suitable smaller region from the acquired palm print to improve the identification method accuracy. Several existing work in the topic of region extraction have been examined. Subsequently, a simple and original method has then proposed for locating the ROI that can be effectively used for palm print analysis. The ROI extracted using this new technique is suitable for different types of processing as it creates a rectangular or square area around the center of activity represented by the lines, wrinkles and ridges of the palm print. The effectiveness of the ROI approach has been tested by integrating it with a texture based identification / authentication system proposed earlier. The improvement has been shown by comparing the identification accuracy rate before and after the ROI pre-processing.

Motivierende Gesprächsführung – Die Fachkräfte der Sozialen Arbeit in ihrer Tätigkeit mit Menschen mit einer Kokainabhängigkeit
Creators: name: Tresch, Jacqueline
Publisher: name: Zenodo
Year: 2022

description: Mit dieser Bachelorarbeit beantwortet die Autorin Jacqueline Tresch die Frage, inwiefern die Fachkräfte der Sozialen Arbeit in ihrer Tätigkeit Menschen mit einer Kokainabhängigkeit begleiten und beraten können. Dabei befasst sie sich mit dem Konzept der motivierenden Gesprächsführung in der spezialisierten Suchthilfe in der Schweiz bei Kokainabhängigkeit. Es wird aufgezeigt, dass das Konzept der motivierenden Gesprächsführung sich vor allem als Ergänzung, Kombination oder vorangestelltes Behandlungselement mit anderen in der Schweizer Suchthilfe erfolgreich angewendeten Methoden eignet, wie beispielsweise dem personenzentrierten, systemischen und dem lösungsorientierten Ansatz. Insgesamt zeigt sich die motivierende Gesprächsführung als eine vielseitige Behandlung, die Verhaltensänderungen in einer Vielzahl von Formaten unterstützen kann. Dabei wurden insbesondere auch internationale Studien berücksichtigt, deren Ergebnisse nach Auffassung der Verfasserin zum grossen Teil auch auf die spezialisierte Suchthilfe in der Schweiz anwendbar sind. Allerdings fehlen in der Schweiz weitgehend repräsentative Daten zur Behandlung von Kokainabhängigen aus der Praxis, um eine solche These untermauern zu können. Diese müsste durch weitere empirische Forschung validiert werden, welche den Rahmen dieser Bachelorarbeit sprengen würde. Ausserdem wurden weitere Vorschläge erarbeitet, wo noch zukünftig im Bereich der motivierenden Gesprächsführung geforscht werden könnte.

description: We address the existence and stability of localized modes in the two-dimensional (2D) linear Schroedinger lattice with two symmetric nonlinear sites embedded into it, and a generalization for moderately localized nonlinearity featuring two distinct symmetric maxima. The latter setting admits a much greater variety of localized modes. Symmetric, antisymmetric, and asymmetric discrete solitons are found, and a subcritical bifurcation, accounting for the spontaneous symmetry breaking (SSB) of the symmetric modes and transition to asymmetric ones, is identified. Existence and stability of more complex 2D solutions in the form of discrete symmetric and asymmetric vortices are also discussed.

description: We report a pilot study with a wide-field laser Doppler detection scheme used to perform laser Doppler anemometry and imaging of particle seeded microflow. The optical field carrying the local scatterers (particles) dynamic state, as a consequence of momentum transfer at each scattering event, is analyzed in the temporal frequencies domain. The setup is based on heterodyne digital holography, which is used to map the scattered field in the object plane at a tunable frequency with a multipixel detector. We show that wide-field heterodyne laser Doppler imaging can be used for quantitative microflow diagnosis; in the presented study, maps of the first-order moment of the Doppler frequency shift are used as a quantitative and directional estimator of the Doppler signature of particles velocity.

description: Deep neural networks can learn powerful prior probability models for images, as evidenced by the high-quality generations obtained with recent score-based diffusion methods. But the means by which these networks capture complex global statistical structure, apparently without suffering from the curse of dimensionality, remain a mystery. To study this, we incorporate diffusion methods into a multi-scale decomposition, reducing dimensionality by assuming a stationary local Markov model for wavelet coefficients conditioned on coarser-scale coefficients. We instantiate this model using convolutional neural networks (CNNs) with local receptive fields, which enforce both the stationarity and Markov properties. Global structures are captured using a CNN with receptive fields covering the entire (but small) low-pass image. We test this model on a dataset of face images, which are highly non-stationary and contain large-scale geometric structures. Remarkably, denoising, super-resolution, and image synthesis results all demonstrate that these structures can be captured with significantly smaller conditioning neighborhoods than required by a Markov model implemented in the pixel domain. Our results show that score estimation for large complex images can be reduced to low-dimensional Markov conditional models across scales, alleviating the curse of dimensionality.

Asymptotic Linear Spectral Statistics for Spiked Hermitian Random Matrix Models

description: Using the Coulomb Fluid method, this paper derives central limit theorems (CLTs) for linear spectral statistics of three "spiked" Hermitian random matrix ensembles. These include Johnstone's spiked model (i.e., central Wishart with spiked correlation), non-central Wishart with rank-one non-centrality, and a related class of non-central $F$ matrices. For a generic linear statistic, we derive simple and explicit CLT expressions as the matrix dimensions grow large. For all three ensembles under consideration, we find that the primary effect of the spike is to introduce an $O(1)$ correction term to the asymptotic mean of the linear spectral statistic, which we characterize with simple formulas. The utility of our proposed framework is demonstrated through application to three different linear statistics problems: the classical likelihood ratio test for a population covariance, the capacity analysis of multi-antenna wireless communication systems with a line-of-sight transmission path, and a classical multiple sample significance testing problem.

description: This paper serves to explain the conceptual performance in archery that affected by psychological relatedness factor. Coaches, teammates and athlete play important role in every sport. Distinguishing and understanding each factor of psychological relatedness is important in determining the athlete’s performance. The inter-relatedness between coach and athlete is vital in bringing out the best performance of athletes. Despites of having advance tools and equipment in archery, however, archer’s performance still can be fluctuated, this may be due to the intangible factor which requires more study in the context.Thus this research served the theoretical explanation that may affect the athlete’s performance. Suggestion and direction of future research is discussed in this paper.
