description: Matrices are essential data representations for many large-scale problems in data analytics; for example, in text analysis under the bag-of-words model, a large corpus of documents are often represented as a matrix. Many data analytic tasks rely on obtaining a summary (a.k.a sketch) of the data matrix. Using this summary in place of the original data matrix saves on space usage and run-time of machine learning algorithms. Therefore, sketching a matrix is often a necessary first step in data reduction, and sometimes has direct relationships to core techniques including PCA, LDA, and clustering. In this dissertation, we study the problem of matrix sketching over data streams. We first describe a deterministic matrix sketching algorithm called FrequentDirections. The algorithm is presented an arbitrary input matrix A∈ Rn&× d one row at a time. It performs O(dl) operations per row and maintains a sketch matrix B ∈ Rl× d such that for any k< l, ||ATA - BTB \|| 2 < ||A - Ak||F2 / (l-k) and ||A - πBk(A)||F2 ≤ (1 + k/l-k)||A-Ak||F2 . Here, Ak stands for the minimizer of ||A - Ak||F over all rank k matrices (similarly Bk), and πBk (A) is the rank k matrix resulting from projecting A on the row span of Bk. We show both of these bounds are the best possible for the space allowed, the sketch is mergeable, and hence trivially parallelizable. We propose several variants of FrequentDirections that improve its error-size tradeoff, and nearly matches the simple heuristic Iterative SVD method in practice. We then describe SparseFrequentDirections for sketching sparse matrices. It resembles the original algorithm in many ways including having the same optimal asymptotic guarantees with respect to the space-accuracy tradeoff in the streaming setting, but unlike FrequentDirections which runs in O(ndl) time, SparseFrequentDirections runs in Õ(nnz(A)l + nl2) time. We then extend our methods to distributed streaming model, where there are m distributed sites each observing a distinct stream of data, and which has a communication channel with a coordinator. The goal is to track an ε-approximation (for ε ∈ (0,1)) to the norm of the matrix along any direction. We present novel algorithms to address this problem. All our methods satisfy an additive error bound that for any unit vector x, | ||A x||2 - ||B x ||2 | ≤ |ε ||A||F2 holds.

description: We consider the following question: How many edge-disjoint plane spanning trees are contained in a complete geometric graph $GK_n$ on any set $S$ of $n$ points in general position in the plane? We show that this number is in $Ω(\sqrt{n})$. Further, we consider variants of this problem by bounding the diameter and the degree of the trees (in particular considering spanning paths).

Objective Cognitive Functioning in Self-Reported Habitual Short Sleepers Not Reporting Daytime Dysfunction: Examination of Impulsivity via Delay Discounting
Creators: name: Curtis, Brian J.
Publisher: name: University of Utah
Year: 2019
Subjects: Clinical psychology

description: In this study, our objectives were to 1) Examine performance on an objective measure of reward-related cognitive impulsivity (delay discounting) among self-reported habitual short sleepers not reporting daytime dysfunction in comparison to those reporting dysfunction and conventional sleepers; 2) Inform the debate regarding what type and duration of short sleep meaningfully influences cognitive impulsivity; 3) Compare the predictive utility of sleep duration and perceived daytime dysfunction to other factors previously shown to influence cognitive impulsivity via delay discounting performance (age, income, education, and fluid intelligence). We analyzed data from 1,190 adults from the Human Connectome Project database. Participants were grouped on whether they reported habitual short (≤ 6 hours) vs. conventional (7 to 9 hours) sleep duration and whether they perceived daytime dysfunction using the Pittsburgh Sleep Quality Index. Results indicated that short sleepers not reporting dysfunction evidenced increased delay discounting compared to conventional sleepers, but were not significantly different from short sleepers reporting dysfunction. Regardless of perceived dysfunction, all short sleepers exhibited increased delay discounting compared to all conventional sleepers. Of the variables examined, self-reported sleep duration was the strongest predictor of delay discounting behavior between groups and across all 1,190 participants. We conclude that individuals who report habitual short sleep are likely to exhibit increased reward-related cognitive impulsivity regardless of whether they perceive sleep-related daytime impairment. Therefore, there is reason to suspect that these individuals exhibit more daytime dysfunction, in the form of reward-related cognitive impulsivity, than they may assume. Current findings suggest that assessment of sleep duration over the prior month has meaningful predictive utility for human reward-related impulsivity.

description: The cost of medication errors is burdensome to patients, institutions, and frontline providers. Nurses are accountable for and vulnerable to institutional safe medication practices and make this responsibility their highest priority; yet, contextual factors relevant to nurses' work encompassing medication administration are not well understood. The aim of this ethnographic study was to identify and describe nurses' work in the context of medication administration, errors, and organizational safety. Using nonparticipant observation (92 hours) and 37 unstructured interviews with nurses, administrators, and pharmacist in a mid-sized hospital in the United States, I found the nature of nurses' work characterized by: 1) chasing a standard of care, 2) prioritizing practice , and 3) renegotiating routines. These characteristics were inextricably linked to organizational structures, the medication management system, competing obligations, and shifting of priorities. Data were divided into two articles: 1) Nurses' Work in the Context of Medication Administration: Untenable Expectations provides a thick description of everyday experiences on the unit, medication administration, and the potential for errors. From these data, I present an emerging theoretical model. 2) The Paradox of Safety in Medication Management is a microanalysis of the medication use process with a specific focus on patterns of medication errors in the hospital, and the role of the pharmacists as a "stop-gap" between the physicians and patients in the recognition and interception of medication errors. These results enhance our understanding of why present efforts targeting the reduction of medication errors may be ineffective.

Databasing on Demand

description: This presentation gives an overview about the motivation for manuscript databases. To build manuscript databases we used the database management tool Heurist which was specifically developed for the Humanities. Heurist allows you to design, populate, explore, and publish data without the need to be a programmer. To insert a large dataset in the database automatically, we developed the databasing on demand (DBoD) approach. The DBoD approach is illustrated in this presentation.

The more databases you have, the more likely you are to find additional data that enriches the existing local information. For this, we need federated searches and a federated database system (FDBS). A FDBS is created by merging databases. Before we implemented a FDBS, we developed a simulation environment to test the communication architecture of the FDBS. But how? You will find the answer at the end of this presentation.

The Sgr B2 X-ray Echo of the Galactic Center Supernova Explosion that Produced Sgr A East

description: The possible impact Sgr A East is having on the Galactic center has fueled speculation concerning its age and the energetics of the supernova explosion that produced it. We have carried out the first in-depth analysis of the remnant's evolution and its various interactions: with the stellar winds flowing out from the inner ~2 pc, with the supermassive black hole, Sgr A*, and with the 50 km/s molecular cloud behind and to the East of the nucleus. We have found that a rather "standard" supernova explosion with energy ~1.5e51 ergs is sufficient to create the remnant we see today, and that the latter is probably only ~1,700 years old. The X-ray Ridge between ~9" and 15" to the NE of Sgr A* appears to be the product of the current interaction between the remaining supernova ejecta and the outflowing winds. Perhaps surprisingly, we have also found that the passage of the remnant across the black hole would have enhanced the accretion rate onto the central object by less than a factor 2. Such a small increase cannot explain the current Fe fluorescence observed from the molecular cloud Sgr B2; this fluorescence would have required an increase in Sgr A*'s luminosity by 6 orders of magnitude several hundred years ago. Instead, we have uncovered what appears to be a more plausible scenario for this transient irradiation--the interaction between the expanding remnant and the 50 km/s molecular cloud. The first impact would have occurred about 1,200 years after the explosion, producing a 2-200 keV luminosity of ~1e39 ergs/s. During the intervening 300-400 years, the dissipation of kinetic energy subsided considerably, leading to the much lower luminosity (~1e36 ergs/s at 2-10 keV) we see today.

description: Recent observations have shown that coronal shocks driven by coronal mass ejections can develop and accelerate particles within several solar radii in large solar energetic particle (SEP) events. Motivated by this, we present an SEP acceleration study including the process that a fast shock propagates through a streamer-like magnetic field with both closed and open field lines in the low corona region. The acceleration of protons is modeled by numerically solving the Parker transport equation with spatial diffusion both along and across the magnetic field. We show that particles can be sufficiently accelerated to up to several hundred MeV within 2-3 solar radii. When the shock propagates through a streamer-like magnetic field, particles are more efficiently accelerated compared to the case with a simple radial magnetic field, mainly due to perpendicular shock geometry and the natural trapping effect of closed magnetic fields. Our results suggest that the coronal magnetic field configuration is an important factor for producing large SEP events. We further show that the coronal magnetic field configuration strongly influences the distribution of energetic particles, leading to different locations of source regions along the shock front where most of high energy particles are concentrated. This work may have strong implications to SEP observations. The upcoming Parker Solar Probe will provide in situ observations for the distribution of energetic particles in the coronal shock region, and test the results of the study.

Nucleotide-Mediated Allostery and Receptor Binding by The Mitochondrial Fission Dynamin

description: The morphology and function of mitochondria, the energy producing organelles of the eukaryotic cell, determine the fate of diverse cellular processes such as metabolic demand, embryonic development, and cell death. The cell uses a dedicated protein based machinery to divide mitochondria for distribution to daughter cells and to ensure faithful distribution of the mitochondrial genome. As a consequence, the impact of this division machinery applies to all processes that are influenced by the mitochondrial network. In mammals, this machinery is composed of the soluble protein Dynamin-Related Protein 1 and its membrane protein receptors Mitochondrial Dynamics 49kDa/51kDa (MiD49/51) and Mitochondrial Fission Factor (Mff). Drp1 forms assemblies that encircle the mitochondria. In addition, it binds and hydrolyzes the nucleotide guanosine triphosphate (GTP) which is thought to provide the necessary energy for mitochondrial membrane fission. Although the importance of these proteins to the mitochondrial fission process is established, the mechanisms by which the receptor proteins recruit and mediate Drp1 activity are unknown. In this dissertation, I present functional and structural analyses of the interaction between Drp1 and its receptor proteins. In Chapter 3, I was a part of a study that showed that each single receptor can recruit Drp1 to the membrane of the mitochondria and cause mitochondrial fission. In Chapter 4, I extended this finding and used cryogenic electron microscopy (cryo-EM) to determine structures of Drp1 bound to MiD49. These structures help us visualize Drp1 conformations in the recruited state on the mitochondrion and establish the role of nucleotide binding and hydrolysis on Drp1 activity. Specifically, we find that Drp1 assumes an extended conformational state upon nucleotide binding. This state enables Drp1 to bind to MiD49 and polymerize into filaments that are structurally suited to encircle mitochondrial tubules. Furthermore, the addition of GTP to this structure induces receptor dissociation and conversion to a ringlike state that is suited to constrict mitochondria. The dimensions of this ring-like state correspond to the Drp1 mediated constrictions observed in human cell cultures. Taken together, this work helps us understand the functional context for multiple receptors in mitochondrial fission and enables us to visualize the conformational dynamics of Drp1 required for its engagement with receptor proteins.

description: We present the first evidence of the decay B- --> tau- nu_tau-bar using 414 fb^-1 of data collected at the Upsilon(4S) resonance with the Belle detector at the KEKB asymmetric-energy e+e- collider. Events are tagged by fully reconstructing one of the B mesons in hadronic modes. We detect the signal with a significance of 4.2 standard deviations including systematics, and measure the branching fraction to be Br(B- --> tau- nu_tau-bar) = (1.06 +0.34-0.28(stat) +0.22-0.25(syst))*10^-4. We also report results based on 1.86 fb^-1 data collected by the Belle detector at the Upsilon(5S) resonance. Several exclusive Bs decays Bs --> Ds^{(*)+} pi- (rho-) and Bs --> J/psi phi(eta) are studied. The Bs meson production is found to proceed predominantly through the creation of Bs^* Bsbar^* pairs. Upper limits on Bs --> K+K-, Bs --> phi gamma, Bs --> gamma gamma and Bs --> Ds^{(*)+} Ds^{(*)-} decays are also reported.

description: We present sub-milliarcsecond resolution total intensity and linear polarization VLBI images of 3C273, using concurrent 43 and 86 GHz data taken with the Very Long Baseline Array in May 2002. The structure seen in the innermost jet suggest that we have fortuitously caught the jet in the act of changing direction. The polarization images confirm that the core is unpolarized (fractional polarization m < 1 %) at 86 GHz, but also show well ordered magnetic fields (m ~ 15 %) in the inner jet, at a projected distance of 2.3 pc from the core. In this strongly polarized region, the rotation measure changes across the jet by 4.2 x 10^{4} rad m^{-2} over an angular width of about 0.3 milliarcseconds. If the lack of polarization in the core is also attributed to a Faraday screen, then a rotation measure dispersion > 5.2 x 10^{4} rad m^{-2} must be present in or in front of that region. These are among the highest rotation measures reported so far in the nucleus of any active galaxy or quasar, and must occur outside (but probably close to) the radio emitting region. The transverse rotation measure gradient is in the same sense as that observed by Asada et al and by Zavala and Taylor at greater core distances. The magnitude of the transverse gradient decreases rapidly with distance down the jet, and appears to be variable.

Novel Strategies Towards Targeting the Long-Term HIV-1 Latent Reservoir
Creators: name: Novis, Camille Leite
Publisher: name: University of Utah

description: Thirty years after the isolation of HIV, despite significant advances in the understanding of the mechanisms of viral pathogenesis, a cure remains out of sight. Despite the effectiveness of combination antiretroviral therapy (ART) at preventing virus replication, a stable, transcriptionally silent viral reservoir within resting memory CD4+ T cells persists and hampers HIV elimination. The current thinking in the field is that a combination of a hypothetical drug that reactivates latent viruses, with current antiretroviral therapy, will be an effective approach toward viral eradication. Several vaccination regimens and pathogen infections have been shown to correlate with a transient increase in the levels of plasma RNA in HIV-1 infected patients even in the presence of ART. Hence, it is tempting to speculate that exposure to microbial products either by vaccination or infection may trigger reactivation of latent viruses. Pathogen infections are primarily sensed through pattern recognition receptors. Toll-like receptors, the most well investigated pattern recognition receptors, are important sentinels of innate host defense. These sensors recognize structural patterns from pathogens and induce an immune response through downstream signaling cascades that, among others, culminate in the activation of NF-kappaB and other transcription factors. Since the viral promoter contains two tandem NF-kappaB binding sites, it is possible to iv speculate that toll-like receptor signaling toward reactivation of latent HIV has recently gained impetus. In this dissertation, I review the emerging body of literature on the correlation between NF-kappaB signaling, as triggered by tolllike receptor engagement, and the reactivation of latent HIV-1. Second, I present our findings that Pam3CSK4, a toll-like receptor-1/2 agonist, can reactivate latent HIV in primary CD4+ T cells in vitro and in cells from aviremic patients. Finally, I described the ability of dynasore, a dynamin inhibitor, to activate latent HIV-1 provirus alone or in synergy with Pam3CSK4, and with well-known latencyreversing agents, such as SAHA, bryostatin-1 and JQ-1. HIV latency is a complex phenomenon controlled by different molecular mechanisms. Although several latency-reversing agents have been described in the literature, the efficacy of these agents to eliminate the transcriptionally silent reservoir in past clinical trials has been limited. Toll-like receptor signaling represents a novel tool in our armamentarium against latent HIV, and therefore deserves further exploration. Throughout the body of this work, I define two novel approaches that could provide us with new therapeutic interventions towards the eradication of the latent reservoir and a cure for HIV/AIDS.

description: We compute the holographic stress tensor and the logarithmic energy-momentum tensor of Einstein-Weyl gravity at the critical point. This computation is carried out performing a holographic expansion in a bulk action supplemented by the Gauss-Bonnet term with a fixed coupling. The renormalization scheme defined by the addition of this topological term has the remarkable feature that all Einstein modes are identically cancelled both from the action and its variation. Thus, what remains comes from a nonvanishing Bach tensor, which accounts for non-Einstein modes associated to logarithmic terms which appear in the expansion of the metric. In particular, we compute the holographic $1$-point functions for a generic boundary geometric source.

description: This paper develops a novel iterative framework for subspace clustering in a learned discriminative feature domain. This framework consists of two modules of fuzzy sparse subspace clustering and discriminative transformation learning. In the first module, fuzzy latent labels containing discriminative information and latent representations capturing the subspace structure will be simultaneously evaluated in a feature domain. Then the linear transforming operator with respect to the feature domain will be successively updated in the second module with the advantages of more discrimination, subspace structure preservation and robustness to outliers. These two modules will be alternatively carried out and both theoretical analysis and empirical evaluations will demonstrate its effectiveness and superiorities. In particular, experimental results on three benchmark databases for subspace clustering clearly illustrate that the proposed framework can achieve significant improvements than other state-of-the-art approaches in terms of clustering accuracy.

description: We present the first detailed simulation of the interaction between the supernova explosion that produced Sgr A East and the wind-swept inner ~ 2-pc region at the Galactic center. The passage of the supernova ejecta through this medium produces an X-ray ridge ~ 9'' to 15'' to the NE of the supermassive black hole Sagittarius A* (Sgr A*). We show that the morphology and X-ray intensity of this feature match very well with recently obtained Chandra images, and we infer a supernova remnant age of less than 2,000 years. This young age--a factor 3--4 lower than previous estimates--arises from our inclusion of stellar wind effects in the initial (pre-explosion) conditions in the medium. The supernova does not clear out the central ~ 0.2-pc region around Sgr~A* and does not significantly alter the accretion rate onto the central black hole upon passage through the Galactic center.

description: In this paper, a novel Full Reference method is proposed for image quality assessment, using the combination of two separate metrics to measure the perceptually distinct impact of detail losses and of spurious details. To this purpose, the gradient of the impaired image is locally decomposed as a predicted version of the original gradient, plus a gradient residual. It is assumed that the detail attenuation identifies the detail loss, whereas the gradient residuals describe the spurious details. It turns out that the perceptual impact of detail losses is roughly linear with the loss of the positional Fisher information, while the perceptual impact of the spurious details is roughly proportional to a logarithmic measure of the signal to residual ratio. The affine combination of these two metrics forms a new index strongly correlated with the empirical Differential Mean Opinion Score (DMOS) for a significant class of image impairments, as verified for three independent popular databases. The method allowed alignment and merging of DMOS data coming from these different databases to a common DMOS scale by affine transformations. Unexpectedly, the DMOS scale setting is possible by the analysis of a single image affected by additive noise.

description: Taming quantum dynamical processes is the key to novel applications of quantum physics, e.g. in quantum information science. The control of light-matter interactions at the single-atom and single-photon level can be achieved in cavity quantum electrodynamics, in particular in the regime of strong coupling where atom and cavity form a single entity. In the optical domain, this requires permanent trapping and cooling of an atom in a micro-cavity. We have now realized three-dimensional cavity cooling and trapping for an orthogonal arrangement of cooling laser, trap laser and cavity vacuum. This leads to average single-atom trapping times exceeding 15 seconds, unprecedented for a strongly coupled atom under permanent observation.

description: From e+e- collision data acquired with the CLEO-c detector at CESR, we search for the non-DDbar decays psi(3770) -> gamma chi_cJ, with chi_cJ reconstructed in four exclusive decays modes containing charged pions and kaons. We report the first observation of such decays for J=0 with a branching ratio of (0.73+-0.07+-0.06)%. The rates for different J are consistent with the expectations assuming psi(3770) is predominantly a 1^3D_1 state of charmonium, but only if relativistic corrections are applied.

description: Software startups face with multiple technical and business challenges, which could make the startup journey longer, or even become a failure. Little is known about entrepreneurial decision making as a direct force to startup development outcome. In this study, we attempted to apply a behaviour theory of entrepreneurial firms to understand the root-cause of some software startup s challenges. Six common challenges related to prototyping and product development in twenty software startups were identified. We found the behaviour theory as a useful theoretical lens to explain the technical challenges. Software startups search for local optimal solutions, emphasise on short-run feedback rather than long-run strategies, which results in vague prototype planning, paradox of demonstration and evolving throw-away prototypes. The finding implies that effectual entrepreneurial processes might require a more suitable product development approach than the current state-of-practice.

description: In recent decades, a great variety of researches and applications concerning Bell nonlocality have been developed with the advent of quantum information science. Providing that Bell nonlocality can be revealed by the violation of a family of Bell inequalities, finding maximal Bell violation (MBV) for unknown quantum states becomes an important and inevitable task during Bell experiments. In this paper we introduce a self-guide method to find MBVs for unknown states using a stochastic gradient ascent algorithm (SGA), by parameterizing the corresponding Bell operators. For all the investigated systems (2-qubit, 3-qubit and 2-qutrit), this method can ascertain the MBV accurately within 100 iterations. Moreover, SGA exhibits significant superiority in efficiency, robustness and versatility compared to other possible methods.

description: Precise optical neural stimulation is an essential element in the use of optogenetics to elicit predictable neural action potentials within the brain, but accessing specific neocortical layers, light scattering, columniation, and ease of tissue damage pose unique challenges to the device engineer. This dissertation presents the design, simulation, microfabrication, and characterization of the Utah Optrode Array (UOA) for precise neural tissue targeting through three main objectives: 1. Maskless wafer-level microfabrication of optical penetrating neural arrays out of soda- lime glass: Utah Optrode Array. 2. Utah Optrode Array customization using stereotactic brain atlases and 3D CAD modeling for optogenetic neocortical interrogation in small rodents and nonhuman primates. 3. Single optrode characterization of the UOA for neocortical illumination. Maskless microfabrication techniques were used to create 169 individual 9 × 9 arrays 3.85 mm × 3.85 mm with 1.1 mm long optrodes from a single two inch glass wafer. The 9 × 9 UOA was too large for precise targeting of the upper layers of the cortex in smaller animals such as mice, so an array customization method was developed using Solidworks and off-the-shelf brain atlases to create 8 × 6 arrays 3.45 mm × 2.45 mm with 400 μm long optrodes. Stereotactic atlases were imported into Solidworks, splined, and lofted together to create a single 3D CAD model of a specific region of interest in the brain. Chronic and acute brain trauma showed excellent results for the 8 × 6 arrays in C57BL/6 wild-type mice (Mus musculus) and macaque monkey (Macaca fascicularis). Simulation, characterization, and radiometric testing of a single optrode of the 9 × 9 array was necessary to prove the ability to transmit light directly to specific tissue. Zemax optical design software was used to predict the light transmission capabilities, and then these results were compared to actual bench-top results. Insertion loss was both predicted and measured to be 3.7 dB. Power budgeting showed 9% of the light was lost at the interfaces of the UOA's backplane and tip in air, and 48% was lost through back-scattering, leaving 43% transmitting through the optrode with no measurable taper loss. Scanning electron microscopy showed small amounts of devitrification of the glass, and atomic force microscopy showed average surface roughness to be 13.5 nm and a root mean square roughness of 20.6 nm. The output beam was profiled in fluorescein dye with a total divergence angle of 63◦ with a cross over distance to adjacent beams at 255 μm.
Extremely Luminous Water Vapor Emission from a Type 2 Quasar at Redshift z = 0.66

description: A search for water masers in 47 Sloan Digital Sky Survey Type 2 quasars using the Green Bank Telescope has yielded a detection at a redshift of z = 0.660. This maser is more than an order of magnitude higher in redshift than any previously known and, with a total isotropic luminosity of 23,000 L_sun, also the most powerful. The presence and detectability of water masers in quasars at z ~ 0.3-0.8 may provide a better understanding of quasar molecular tori and disks, as well as fundamental quasar and galaxy properties such as black hole masses. Water masers at cosmologically interesting distances may also eventually provide, via direct distance determinations, a new cosmological observable for testing the reality and properties of dark energy, currently inferred primarily through Type 1a supernova measurements.

description: Software firms participate in an ecosystem as a part of their innovation strategy to extend value creation beyond the firms boundary. Participation in an open and independent environment also implies the competition among firms with similar business models and targeted markets. Hence, firms need to consider potential opportunities and challenges upfront. This study explores how software firms interact with others in OSS ecosystems from a coopetition perspective. We performed a quantitative and qualitative analysis of three OSS projects. Finding shows that software firms emphasize the co-creation of common value and partly react to the potential competitiveness on OSS ecosystems. Six themes about coopetition were identified, including spanning gatekeepers, securing communication, open-core sourcing and filtering shared code. Our work contributes to software engineering research with a rich description of coopetition in OSS ecosystems. Moreover, we also come up with several implications for software firms in pursing a harmony participation in OSS ecosystems.
