Empirical Green's Function Approach for Utilizing Millisecond Focal and Pupil Plane Telemetry in Exoplanet Imaging
Creators: name: Frazin, Richard A.
Publisher: name: arXiv
Year: 2016
Subjects: subject: Instrumentation and Methods for Astrophysics (astro-ph.IM)
subject: FOS: Physical sciences

description: Millisecond focal plane telemetry is now becoming practical due to a new generation of near-IR detector arrays with sub-electron noise that are capable of kHz readout rates. Combining these data with those simultaneously available from the wavefront sensing system allows the possibility of self-consistently determining the optical aberrations (the cause of quasi-static speckles) and the planetary image. This approach may be especially advantageous for finding planets within about 3 $λ/ D$ of the star where differential imaging is ineffective. As shown in a recent article by the author (J. Opt. Soc. Am. A., 33, 712, 2016), one must account for unknown aberrations in several non-conjugate planes of the optical system, which, in turn, requires ability to computational propagate the field between these planes. These computations are likely to be difficult to implement and expensive. Here, a far more convenient alternative based on empirical Green's functions is provided. It is shown that the empirical Green's function (EGF), which accounts for all multi-planar, non-common path aberrations, and results in a much more tractable and highly parallel computational problem. It is also shown that the EGF can be generalized to treat polarization, resulting in the empirical Green's tensor (EGT).

Publisher: name: National Academic Digital Repository of Ethiopia
Year: 2016

description: Studies have shown that good corporate governance (CG) have led to significant increases in economic value added of firms, higher productivity, and lower risk of systemic financial failures for countries. On top of this the purpose of this study is to analyze effects of corporate governance mechanisms on the performance of Ethiopian MFIs. From the total of 34 MFIs which are operating in the country, five MFIs have been selected for the study by way of a purposive sampling technique and six corporate governance variables (board size, educational qualification of boards, audit committee size, board gender diversity, business management experience of boards and industry specific experience of boards) have been used for the study. On the other hand, financial performance was measured using two variables (return on asset and return on equity). The study also used leverage, growth and capital adequacy ratio of MFIs as control variables. The effect of CG examined by using panel data from year 2005 to year 2014 gathered from the audited financial statements of five sample MFIs and the study used quantitative research approach. Secondary financial data were analyzed by using multiple linear regression models for two profitability measures (ROE and ROA).The empirical result shows board size, gender diversity and size of audit committee have negative and significant relationship with performance of MFIs while industry specific experience and educational qualification of the board have positive relationship; and the effect of business management experience of directors on performance is inconclusive. Based on the result of the study, it is recommended that board and audit committee sizes should be kept low. Gender diversity of the board should also be maintained and attention should be given for the capacity development of women.

description: Ensuring the trustworthiness and interpretability of machine learning models is critical to their deployment in real-world applications. Feature attribution methods have gained significant attention, which provide local explanations of model predictions by attributing importance to individual input features. This study examines the generalization of feature attributions across various deep learning architectures, such as convolutional neural networks (CNNs) and vision transformers. We aim to assess the feasibility of utilizing a feature attribution method as a future detector and examine how these features can be harmonized across multiple models employing distinct architectures but trained on the same data distribution. By exploring this harmonization, we aim to develop a more coherent and optimistic understanding of feature attributions, enhancing the consistency of local explanations across diverse deep-learning models. Our findings highlight the potential for harmonized feature attribution methods to improve interpretability and foster trust in machine learning applications, regardless of the underlying architecture.

description: Agile rf sources are a common requirement for control systems in quantum science and technology platforms. The direct digital synthesizer (DDS) often fills this role by allowing programmable control of the rf signals. Due to limitations of the DDS architecture, implementing an agile rf source requires rapid and precisely-timed programming of discrete updates that restrict the source's agility. Here, we describe a microcontroller-based interface that exploits the DDS's internal linear sweep accumulator to perform both sequential linear sweeps, and standard discrete updates, at the ~10$μ$s scale. This allows updates to the swept parameter as fast as every 8 ns with greatly reduced communication and memory overhead. We demonstrate the utility of this system by using it as the reference to an optical phase-locked-loop to implement rapid, adjustable laser frequency sweeps in a Rydberg Electromagnetically Induced Transparency spectroscopy measurement.

description: We present initial work about attaining fitting formulas for the quick determination of the existence of S-type and P-type habitable zones in binary systems. Following previous work, we calculate the limits of the climatological habitable zone in binary systems (which sensitively depend on the system parameters) based on a joint constraint encompassing planetary orbital stability and a habitable region for a possible system planet. We also consider updated results on planetary climate models previously obtained by Kopparapu and collaborators. Fitting equations based on our work are presented for selected cases.

description: Spatial architecture is a high-performance architecture that uses control flow graphs and data flow graphs as the computational model and producer/consumer models as the execution models. However, existing spatial architectures suffer from control flow handling challenges. Upon categorizing their PE execution models, we find that they lack autonomous, peer-to-peer, and temporally loosely-coupled control flow handling capability. This leads to limited performance in intensive control programs. A spatial architecture, Marionette, is proposed, with an explicit-designed control flow plane. The Control Flow Plane enables autonomous, peer-to-peer and temporally loosely-coupled control flow handling. The Proactive PE Configuration ensures timely and computation-overlapped configuration to improve handling Branch Divergence. The Agile PE Assignment enhance the pipeline performance of Imperfect Loops. We develop full stack of Marionette (ISA, compiler, simulator, RTL) and demonstrate that in a variety of challenging intensive control programs, compared to state-of-the-art spatial architectures, Marionette outperforms Softbrain, TIA, REVEL, and RipTide by geomean 2.88x, 3.38x, 1.55x, and 2.66x.

Year: 2015

description: This study examines internal audit practice in Somali regional government public offices, population of the study were 101 internal audit staffs and 80 internal auditors were selected as sample size using simple random sampling. The study investigates key problems in internal audit practices regarding the organizational policy authorizing internal audit, auditee cooperation, independence and objectivity, proficiency and scope of work of internal audit, reporting follow-up and quality review, and planning of internal audit unit. The study adopts mixed method approach in order to achieve the research objectives and to answer research questions. Specifically, the techniques used in the study include survey with internal auditors, documentary analysis and in-depth interviews with financial control support process owners (internal audit department heads). With these research methods, the results of the study reveal that organizational policy authorizing internal audit and reporting follow up and are in line with the standards. But there is lack of auditee cooperation to the internal audit staffs, audit planning is not considered organizational risk profile, independence and objectivity of internal auditors are impaired and quality assurance is not carried out that leads ineffectiveness of internal audit. In the end, the study forwards that both Somali regional state government sector offices and internal audit staffs in the region to should work with the ISPPIA standards formulated by IIA's to mitigate challenges in the internal audit practice in the region.

description: We study the asymptotic bipartite entanglement entropy of the quantum trajectories of a free-fermionic system, when subject to a continuous nonlocal monitoring. The measurements are described by Gaussian-preserving two-point operators, whose strength decays as a power-law with exponent $α$. Different behaviors of the entanglement entropy with the system size emerge: for $α$ below a given threshold value a volume-law behavior sets in, while for larger $α$ we observe a transition from subvolume to area-law, whose exact location depends on the measurements rate and on the presence of a Hamiltonian dynamics. We also consider the expectation probability distribution of the measurement operators, and find that this distribution features a transition from a unimodal to a bimodal shape. We discuss the possible connections between this qualitative change of the distribution and the entanglement transition points.

description: We present radial velocities and chemical abundances for red giant branch stars in the Galactic bulge globular clusters NGC 6342 and NGC 6366. The velocities and abundances are based on measurements of high resolution (R > 20,000) spectra obtained with the MMT-Hectochelle and WIYN-Hydra spectrographs. We find that NGC 6342 has a heliocentric radial velocity of +112.5 km/s (sigma = 8.6 km/s), NGC 6366 has a heliocentric radial velocity of -122.3 km/s (sigma = 1.5 km/s), and that both clusters have nearly identical metallicities ([Fe/H] ~ -0.55). NGC 6366 shows evidence of a moderately extended O-Na anti-correlation, but more data are needed for NGC 6342 to determine if this cluster also exhibits the typical O-Na relation likely found in all other Galactic globular clusters. The two clusters are distinguished from similar metallicity field stars as having larger [Na/Fe] spreads and enhanced [La/Fe] ratios, but we find that NGC 6342 and NGC 6366 display alpha and Fe-peak element abundance patterns that are typical of other metal-rich ([Fe/H] > -1) inner Galaxy clusters. However, the median [La/Fe] abundance may vary from cluster-to-cluster.

Thereby, the Lorentz violation encoded into the constraint that defines the NANM is physically unobservable. As result, the Goldstone bosons in the NANM arising from the spontaneous symmetry breaking can be identified as the standard gauge fields.

Publisher: name: National Academic Digital Repository of Ethiopia
Year: 2016

description: This paper presents an empirical study of selection criteria employed by multiple bank users. The study chose to sample a specific consumer segment in Addis Ababa, namely business person and employees. The purpose of this study is to examine the significance of bank selection criteria on multiple bank users and how customers rank the factors based on their importance level to patronize multiple banks and banking services. Both quantitative and qualitative methodology, incorporating 193 respondents is employed in the analysis. A non- probability convenience sampling was used due to the unavailability of sampling frame of bank customers' or infinite population and data was factor analyzed to reduce the number of total variables in to manageable way. Findings show that Branch location and Availability of ATM are influential and significantly more important in prompting choice of multiple banks. This finding indicates that bank customers' place great emphasis on the attribute of saving time and many customers place great emphasis on their banks offering locational convenience. Proximity and Service provision are also significantly more important in prompting multiple banks. Therefore; such factors should be considered seriously by the commercial banks in designing their marketing strategies by expanding their branches and ATM availability with convenient location and providing good customers services to customers. Banks also have to work on the above areas to understand the needs of the client and have to implement strategies to satisfy the needs in order to retain their existing clients and attract new clients. It is interesting to know that influential marketing campaign is significantly less that customers did not choose the second or above banks depending on influential marketing campaign rather they select based on other criteria. The implications of the findings were discussed and opportunities for future research were provided. Keywords: Multiple banks selection criteria, multiple bank users, banking services, business person and employees

Reproducibility of density functional approximations: how new functionals should be reported

Year: 2023

description: Density functional theory is the workhorse of chemistry and materials science, and novel density functional approximations (DFAs) are published every year. To become available in program packages, the novel DFAs need to be (re)implemented. However, according to our experience as developers of Libxc [Lehtola et al, SoftwareX 7, 1 (2018)], a constant problem in this task is verification, due to the lack of reliable reference data. As we discuss in this work, this lack has lead to several non-equivalent implementations of functionals such as BP86, PW91, PBE, and B3LYP across various program packages, yielding different total energies. Through careful verification, we have also found many issues with incorrect functional forms in recent DFAs. The goal of this work is to ensure the reproducibility of DFAs: DFAs must be verifiable in order to prevent reappearances of the abovementioned errors and incompatibilities. A common framework for verification and testing is therefore needed. We suggest several ways in which reference energies can be produced with free and open source software, either with non-self-consistent calculations with tabulated atomic densities or via self-consistent calculations with various program packages. The employed numerical parameters -- especially, the quadrature grid -- need to be converged to guarantee a $\lesssim0.1μE_{h}$ precision in the total energy, which is nowadays routinely achievable in fully numerical calculations. Moreover, as such sub-$μE_{h}$ level agreement can only be achieved when fully equivalent implementations of the DFA are used, also the source code of the reference implementation should be made available in any publication describing a new DFA.

description: The interest in tellurium nanostructures is on the rise due to their outstanding physical properties including high carrier mobility, anisotropic charge conduction, photoconductivity, thermoelectricity, and piezoelectricity. Applications in related technologies require tailoring the synthesis of tellurium from its preferred vertical growth toward the lateral growth. Here, the synthesis of pillar-like and pennette-like structures of tellurium through a powder vapor deposition technique has been discussed. It has been shown that exploiting salt additives such as NaCl in vapor deposition technique can enhance tellurium pillar dimensionality toward large planar grains. Further, we report on the synthesis of hexagonal ultrathin tellurium nanoflakes, namely tellurene, from few-layer to monolayer thickness by optimizing the growth kinetics without the usage of any additives. In addition, we explore the surface quality and physical properties of as-grown two-dimensional (2D) tellurium, using a variety of characterization techniques, including Raman spectroscopy, scanning electron microscopy, atomic force microscopy, and Kelvin probe force microscopy. This study provides a pivotal scheme for enabling scalable 2D tellurium integration in numerous potential applications for electronics and optoelectronic devices.

description: We study the gravitational scattering of ultrarelativistic neutrinos off a rotating supermassive black hole (BH) surrounded by a thick magnetized accretion disk. Neutrinos interact electroweakly with background matter and with the magnetic field in the disk since neutrinos are supposed to possess nonzero magnetic moments. The interaction with external fields results in neutrino spin oscillations. We find that the toroidal magnetic field, inherent in the magnetized Polish doughnut, does not cause a significant spin-flip for any reasonable strengths of the toroidal component. The reduction of the observed neutrino flux, owing to neutrino spin oscillations, is predicted. A poloidal component of the magnetic field gives the main contribution to the modification of the observed flux. The neutrino interaction with matter, rotating with relativistic velocities, also changes the flux of neutrinos. We briefly discuss the idea of the neutrino tomography of magnetic field distributions in accretion disks near BHs.

description: This paper aimed to contribute to the existing literature pertaining to the relationship between alcohol and criminal offenses by analyzing a 2016 dataset of state and federal inmates from the Bureau of Justice Statistics. Our analysis examined variables related to alcohol consumption at the time of the offense, criminal offenses, in-prison support (via alcohol treatment and counseling), and various inmate demographics. We addressed two research questions that asked whether alcohol consumption at the time of the offense was related to various offenses and whether inmates who were incarcerated for alcohol-related offenses that are getting help in prison were doing so voluntarily or because they were mandated to. Chi square tests found that, between inmates who did consume alcohol at the time of the offense and inmates who did not consume alcohol at the time of the offense, race and education level were not important demographic variables, but age was. With respect to our first research question, logistic regression analysis identified the offenses of homicide, sex crime, robbery, assault, burglary, drug possession, and other public order offenses as significant predictors of alcohol consumption at the time of the offense. With respect to our second research question, logistic regression analysis found that inmates who are receiving counseling as part of their sentence is a significant predictor of inmates who consumed alcohol at the time of their offense that are getting help in prison, indicating that inmates are receiving support but that this support is not voluntary on their part.
Hierarchical Skeleton Meta-Prototype Contrastive Learning with Hard Skeleton Mining for Unsupervised Person Re-Identification

description: With rapid advancements in depth sensors and deep learning, skeleton-based person re-identification (re-ID) models have recently achieved remarkable progress with many advantages. Most existing solutions learn single-level skeleton features from body joints with the assumption of equal skeleton importance, while they typically lack the ability to exploit more informative skeleton features from various levels such as limb level with more global body patterns. The label dependency of these methods also limits their flexibility in learning more general skeleton representations. This paper proposes a generic unsupervised Hierarchical skeleton Meta-Prototype Contrastive learning (Hi-MPC) approach with Hard Skeleton Mining (HSM) for person re-ID with unlabeled 3D skeletons. Firstly, we construct hierarchical representations of skeletons to model coarse-to-fine body and motion features from the levels of body joints, components, and limbs. Then a hierarchical meta-prototype contrastive learning model is proposed to cluster and contrast the most typical skeleton features ("prototypes") from different-level skeletons. By converting original prototypes into meta-prototypes with multiple homogeneous transformations, we induce the model to learn the inherent consistency of prototypes to capture more effective skeleton features for person re-ID. Furthermore, we devise a hard skeleton mining mechanism to adaptively infer the informative importance of each skeleton, so as to focus on harder skeletons to learn more discriminative skeleton representations. Extensive evaluations on five datasets demonstrate that our approach outperforms a wide variety of state-of-the-art skeleton-based methods. We further show the general applicability of our method to cross-view person re-ID and RGB-based scenarios with estimated skeletons.

description: This work aims to study the radiative corrections in a vector model with spontaneous Lorentz symmetry violation, known in the literature as the bumblebee model. We consider such a model with self-interaction quadratic smooth potential responsible for spontaneous Lorentz symmetry breaking. The spectrum of this model displays a transversal nonmassive mode, identified as Nambu-Goldstone, and a massive longitudinal mode. Besides the Lorentz symmetry, this model also exhibits gauge symmetry violation. To restore the gauge symmetry, we introduce the Stueckelberg field and calculate the two-point function by employing the principal-value (PV) prescription. The result is nontransversal, leading to a massive excited mode.

description: To establish the proportion of patients with retinitis pigmentosa (RP) meeting the Australian fitness to drive (FTD) visual standards. A prospective consecutive case series of patients with a clinical or genetic diagnosis of RP. Data on age at symptom onset, current driving status, inheritance pattern, better eye visual acuity (BEVA), binocular Esterman visual field (BEVF) parameters, genotype and ability to meet the driving standards based on BEVA and BEVF were collected. Outcome measures included the proportion of RP patients overall meeting the standards and clinical predictors for passing. A sub-analysis was performed on those RP patients who reported to drive. Change in BEVA and BEVF parameters across age in specific genotype groups was assessed. Overall, 228 patients with RP had a BEVF assessment. Only 39% (89/228) met the driving standards. Younger age at the time of testing was the only significant predictor (p < 0.01) for passing. Of the 55% of RP patients who reported to drive, 52% (65/125) met the standards, decreasing to 14% in the 56- to 65-year-old age group. RP patients harbouring mutations in HK1 or RHO genes may have slower rates of decline in their VF parameters. Nearly 40% of RP patients met the driving standards. However, almost 50% of RP drivers were unaware of their failure to meet the current standards. BEVF testing is essential in the assessment of RP patients who are still driving. Phenotype and genotype predictors for passing the standards warrant further investigation.

description: In the field of medical imaging, 3D deep learning models play a crucial role in building powerful predictive models of disease progression. However, the size of these models presents significant challenges, both in terms of computational resources and data requirements. Moreover, achieving high-quality pretraining of 3D models proves to be even more challenging. To address these issues, hybrid 2.5D approaches provide an effective solution for utilizing 3D volumetric data efficiently using 2D models. Combining 2D and 3D techniques offers a promising avenue for optimizing performance while minimizing memory requirements. In this paper, we explore 2.5D architectures based on a combination of convolutional neural networks (CNNs), long short-term memory (LSTM), and Transformers. In addition, leveraging the benefits of recent non-contrastive pretraining approaches in 2D, we enhanced the performance and data efficiency of 2.5D techniques even further. We demonstrate the effectiveness of architectures and associated pretraining on a task of predicting progression to wet age-related macular degeneration (AMD) within a six-month period on two large longitudinal OCT datasets.

description: An Electron-Ion Collider (EIC) with center-of-mass energies sqrt(s_{eN}) ~ 20-100 GeV and luminosity L ~ 10^{34} cm^{-2} s^{-1} would offer new opportunities to study heavy quark production in high-energy electron or photon scattering on protons and nuclei. We report about an R&D project exploring the feasibility of direct measurements of nuclear gluon densities at large x (gluonic EMC effect, antishadowing) using open charm production at EIC. We describe the charm production rates and angle-momentum distributions at large x and discuss methods of charm reconstruction using next-generation detector capabilities (pi/K identification, vertex reconstruction). The results can be used also for other physics applications of heavy quark production at EIC (fragmentation functions, jets, heavy quark propagation in nuclei).

title: Oppressed Men: Depictions of Male Troubles and A Critique of Hegemonic Masculinity in West African Women’s Writing (1970-2017)

description: ‘Oppressed Men: Depictions of Male Troubles and A Critique of Hegemonic Masculinity in West African Women’s Writing (1970-2017)’ analyses fictional depictions of hegemonic masculinity in Anglophone and Francophone postcolonial literature written by Sub-Saharan female writers, namely, Flora Nwapa’s Idu, Buchi Emecheta’s The Joys of Motherhood, Mariama Bậ’s Scarlet Song, Ama Ata Aidoo’s Changes: A Love Story, Ayobami Adebayo’s Stay With Me. My study explores the ways in which constructions of masculinities in the novels engage with Sub-Saharan ideals of patriarchy, traditions, and foreign forces, such as colonialism and modernity across time. I investigate male characters’ possibility of maintaining a balance between traditional West African roles as husbands and fathers and new alternative modes of masculinity. I also examine depictions of convergent and divergent forms of hegemonic masculinity in each context from the pre-colonial to the contemporary period as well as their detrimental effects on male characters and on marginalised/subordinated masculinities, thus, offering an alternative perception of hegemonic masculinity. Drawing on masculinity studies and postcolonial theory, this thesis identifies the complexity and constancy of Sub-Saharan ideals of hegemonic masculinity across time. I argue that hegemonic masculinity is presented as a problematic position as manifested through the psychological and emotional afflictions of the male characters under study, such as anxiety, bewilderment, and humiliation. Hegemonic masculinity is shown to be persistently and inextricably related to pre-colonial patriarchy and traditions; whereas it firmly resists change brought by colonialism and its aftermath. While highlighting recurrent and emerging tensions in Sub-Saharan masculinity, my project recognizes the similarities and dissimilarities in the textual as well as the contextual constructions of masculinities across the novels. Hence, my research contributes and expands postcolonial studies as well as the existing scholarship on masculinity in the selected narratives. By analysing depictions of hegemonic masculinity, my project extends debates about African women’s portrayal of men, seeking the possibility to push beyond a study of masculinism. With this aim in my mind, I hope to encourage a better, more nuanced engagement with hegemonic masculinity in African literature and women’s writing, in particular.

description: The plasma thermodynamics in the solar upper atmosphere, particularly in the corona, are dominated by the magnetic field, which controls the flow and dissipation of energy. The relative lack of knowledge of the coronal vector magnetic field is a major handicap for progress in coronal physics. This makes the development of measurement methods of coronal magnetic fields a high priority in solar physics. The Hanle effect in the UV and IR spectral lines is a largely unexplored diagnostic. We use magnetohydrodynamic (MHD) simulations to study the magnitude of the signal to be expected for typical coronal magnetic fields for selected spectral lines in the UV and IR wavelength ranges, namely the H I Ly-$α$ and the He I 10830 Å lines. We show that the selected lines are useful for reliable diagnosis of coronal magnetic fields. The results show that the combination of polarization measurements of spectral lines with different sensitivities to the Hanle effect may be most appropriate for deducing coronal magnetic properties from future observations.

description: We review recent trends on inflationary dynamics in the context of viable modified gravity theories. After providing a general overview of the inflationary paradigm emphasizing on what problems of hot Big Bang theory inflation solves, and a somewhat introductory presentation of single field inflationary theories with minimal and non-minimal couplings, we review how inflation can be realized in terms of several string motivated models of inflation, which involve Gauss-Bonnet couplings of the scalar field, higher order derivatives of the scalar field, and some subclasses of viable Horndeski theories. We also present and analyze inflation in the context of Chern-Simons theories of gravity, including various subcases and generalizations of string corrected modified gravities which also contain Chern-Simons correction terms, with the scalar field being identified with the invisible axion, which is the most viable to date dark matter candidate. We also provide a detailed account of vacuum $f(R)$ gravity inflation, and also inflation in $f(R,ϕ)$ and kinetic-corrected $f(R,ϕ)$ theories of gravity. In the end of the review we discuss the technique for calculating the overall effect of modified gravity on the waveform of the standard general relativistic gravitational wave form.
