description: Aims: We investigate the X-ray spectral and timing properties of the high mass X-ray binary EXO 2030+375 observed during its June-September 2006 giant (type II) outburst. Methods: The data analyzed in this work are from partly simultaneous observations with INTEGRAL Swift. The pulse period P and its temporal derivative P_dot are measured. X-ray pulse profiles in different energy ranges and time intervals are constructed. Pulse averaged X-ray spectra for different time intervals are studied. Results: We report a strong spin-up of the source during the outburst, comparable to that observed in 1985 during the previous giant outburst when the source was discovered. The value of P_dot is found to be linearly related to the X-ray luminosity of the source during the outburst. For the first time the hard X-ray (>25 keV) characteristics of the source during a type II outburst are studied. The X-ray pulse profiles apparently change with luminosity. The X-ray spectral continuum in the 3--120 keV energy range is modeled with an absorbed power law with an exponential cutoff around E ~26 keV. An iron emission line at ~6-7 keV is observed. The spectrum reveals some features between 10 and 20 keV which can be modeled either by a broad emission line at ~13-15 keV (a ``bump'') or by two absorption lines at ~10 and ~20 keV.

Subjects: Uncategorized

description: Pediatric hematopoietic stem cell transplantation (HSCT) has a reported high mortality rate of up to 40% during the first year, prolonged hospitalizations, and uncertainty related to the prognosis of outcomes. These challenges cause families to suffer significant psychological effects surrounding pediatric HSCT. The purpose of this study was 1) to explore how families are best supported through the acute phase of HSCT when the child is hospitalized, from the perspectives of the parents and the pediatric nurses caring for these children, and 2) to explore the challenges that parents face during their child’s HSCT hospitalization and how parents cope and adapt to this experience. A qualitative descriptive design was used with the guidance of an adapted Resiliency Model of Family Stress, Adjustment, and Adaptation conceptual framework. Parents from six families (n=10) and pediatric oncology nurses (n=15) were recruited to participate in semi-structured interviews about family support, stressors, coping, and adaptation, during the pediatric HSCT experience. The conceptual framework guided the interviews, analytic methods, and summation process. Community resources most commonly included religion, disease specific foundations, and schools, with social support encompassing support groups, and social media. Grandparents were the most common extended family support mentioned, and nurses provided the most support within the healthcare team. Parents were perceived more stressed managing family obligations, seeing the sick child, lacking in information, and experiencing transplant-related complications. Although some parents remained hopeful and positive, others described avoidance behaviors to cope. The family working as a team was the most prominent adaptation strategy, in which parents established new routines and role change to manage their child’s illness. Support groups and support from individuals experiencing the same illness were seen as most beneficial, and family presence during the hospitalization was perceived as crucial for support of the child. Continued positivity helps families adjust to the stressors of pediatric HSCT. However, parents should be assessed for family support structures and increased stressors prior to the HSCT, and those lacking coping and adaptation skills will require more psychosocial interventions during the children’s hospitalization for HSCT.

Self-Explanation Use in Nurse Practitioner Student Diagnostic Reasoning

Subjects: Uncategorized

description: There is a major gap in educational best-practices regarding how to scholastically foster diagnostic accuracy among Nurse Practitioner (NP) students. This research establishes foundational information that will lead to evidenced-based educational interventions and curricular changes leveraging the technique of self-explanation in order to increase NP diagnostic accuracy. Self-explanation is defined as generating explanations for oneself while problem-solving, in attempts to make sense of new information. Because different types of self-explanations enhance learning to varying degrees, identifying high quality ways of self-explaining present among successful NP student diagnosticians is a critical step in advancing diagnostic reasoning education. In this mixed methods content analysis study, NP students were asked to solve written case studies while self-explaining out loud. Self-explanations were analyzed both qualitatively and quantitatively. The initial research question of this study was: How do NP students self-explain during diagnostic reasoning? Using iterative, qualitative analysis techniques, 17 categories of NP student diagnostician self-explanation emerged. Inference self-explanations include both clinical and biological foci. Non-inference self-explanations monitor students’ understanding of clinical data, and reflect shallow information processing. Two research aims sought to quantitatively explore qualitative findings. Aim one was to compare differences between student expertise levels in terms of diagnostic accuracy scores and self-explanation scores. Expert students self-explain in qualitatively different ways than novice students, utilizing more biological and clinical inference self-explanations and less non-inferences statements. Groups did not significantly differ in terms of diagnostic accuracy (p<0.1636). Aim two was to explore relationships among ways of self-explaining and diagnostic accuracy levels. Clinical inferences were not significantly associated with levels of diagnostic accuracy (p<0.39). Biological inference scores were, however, significantly associated with diagnostic accuracy scores, r(35)=0.49 (p<0.002). Collectively, these findings provide a solid framework for NP educators to support diagnostic accuracy among students via self-explanation. Prompted self-explanation interventions and curriculum changes integrating disease state courses and human sciences will encourage students to self-explain clinical features in terms of underlying biology. Cultivating the momentum created by this research will, ultimately, mitigate a major issue in today’s healthcare system through promotion of accurate diagnoses and patient well-being.

description: Ischemic heart disease (IHD) is the leading cause of mortality worldwide and can be complicated by myocardial infarction (MI), leading to cardiac failure. Inorganic nitrite and nitrate, which release nitric oxide (NO), can protect the heart against myocardial injury. This animal systematic review and meta-analysis aims to assess whether the administration of nitrite/nitrate decreases myocardial infarct size. We systematically searched PubMed, Scopus, and Web of Science databases until October 2023; 15 eligible animal studies (35 study arms for in-vivo and 10 for in-vitro studies) published between 1989 and 2023 were included. In-vivo studies were conducted on rats, mice, cats, and dogs, and in-vitro studies on rats and mice with an overall exposure of 0.03 to 12713 mg/kg to nitrate/nitrite administrated before, after, or during ischemia mainly by intravenous single bolus or by oral over 270 days. All in-vitro studies used nitrite/nitrate before ischemia, with the concentration ranging between 0.34 to 201 μM. MI was induced by occlusion of the left anterior diagonal or left circumflex arteries in in-vitro studies and by isoproterenol in in-vivo studies. Infarct size was measured by direct staining of the sliced heart sections. In in-vivo studies, nitrite (overall effect size (ES)=-17.0 %, 95 % confidence interval (CI)=-21.3, -12.8, P<0.001) and nitrate (overall ES= -9.6 %, 95 % CI=-15.7, -3.4, P=0.002) reduced myocardial infarct size. In in-vitro studies, nitrite (overall ES=-15.8 %, 95 % CI=-25.5, -6.2, P=0.001) reduced the infarct size. Sensitivity analysis showed that the overall effect of nitrite on myocardial infarct size was unaffected by doses or health conditions in in-vivo and in-vitro studies. In conclusion, our meta-analysis showed that nitrite/nitrate administration can effectively reduce myocardial infarct size. However, these results should be approached with caution because of the limitations of animal studies and the existing high heterogeneity.

Galaxy Bulge Formation: Interplay with Dark Matter Halo and Central Supermassive Black Hole

description: We present a simple scenario where the formation of galactic bulges was regulated by the dark halo gravity and regulated the growth of the central supermassive black hole. Assuming the angular momentum is low, we suggest that bulges form in a runaway collapse due to the "gravothermal" instability once the central gas density or pressure exceeds certain threshold (Xu & Zhao 2007). We emphasize that the threshold is nearly universal, set by the background NFW dark matter gravity $g_{DM} \sim 1.2 \times 10^{-8}{\rm cm} {\rm sec}^{-2}$ in the central cusps of halos. Unlike known thresholds for gradual formation of galaxy disks, we show that the universal "halo-regulated" star formation threshold for spheroids matches the very high star formation rate and star formation efficiency shown in high-redshift observations of central starburst regions. The starburst feedback also builds up a pressure shortly after the collapse. This large pressure could both act outward to halt further infall of gas from larger scale, and act inward to counter the Compton-thick wind launched from the central black hole in an Eddington accretion. Assuming the feedback balancing inward and outward forces, our scenario naturally gives rise to the black hole-bulge relationships observed in the local universe.

description: Chest X-ray (CXR) is a low-cost medical imaging technique. It is a common procedure for the identification of many respiratory diseases compared to MRI, CT, and PET scans. This paper presents the use of generative adversarial networks (GAN) to perform the task of lung segmentation on a given CXR. GANs are popular to generate realistic data by learning the mapping from one domain to another. In our work, the generator of the GAN is trained to generate a segmented mask of a given input CXR. The discriminator distinguishes between a ground truth and the generated mask, and updates the generator through the adversarial loss measure. The objective is to generate masks for the input CXR, which are as realistic as possible compared to the ground truth masks. The model is trained and evaluated using four different discriminators referred to as D1, D2, D3, and D4, respectively. Experimental results on three different CXR datasets reveal that the proposed model is able to achieve a dice-score of 0.9740, and IOU score of 0.943, which are better than other reported state-of-the art results.

description: In spacetimes of any dimensionality, the massless particle states that can be created and destroyed by a field in a given representation of the Lorentz group are severely constrained by the condition that the invariant Abelian subgroup of the little group must leave these states invariant. A number of examples are given of the massless one-particle states that can be described by various tensor and spinor-tensor fields, and a speculation is offered for the general case.

Cool Stars on the main sequence

description: Hydrodynamical simulations are very efficient tools to study the internal structure of stars but the wide range of time and length scales that characterize it makes it difficult to model. To cope this difficulty a common practice when modelling stellar convection is to artificially increase luminosity and thermal diffusivity by several order of magnitude. The reasons for using this artefact is for numerical stability and/or for achieving thermal relaxation We perform fully compressible 2D simulations of solar-like models using the numerical time-implicit code MUSIC. This work focuses on the impact such a practice could have on physical process like convective penetration and internal gravity waves. To do so we compare solar-like models with different enhancement factors for the luminosity and thermal diffusivity.

description: The principle of self-organization has acquired a fundamental significance in the newly emerging field of computational philosophy. Self-organizing systems have been described in various domains in science and philosophy including physics, neuroscience, biology and medicine, ecology, and sociology. While system architecture and their general purpose may depend on domain specific concepts and definitions, there are at least seven key properties of self-organization clearly identified in brain systems: modular connectivity, unsupervised learning, adaptive ability, functional resiliency, functional plasticity, from-local-to-global functional organization and dynamic system growth. These are defined here in the light of insight from neurobiology, cognitive neuroscience and Adaptive Resonance Theory (ART), and physics to show that self-organization achieves stability and functional plasticity while minimizing structural system complexity. A specific example informed by empirical research is discussed to illustrate how modularity, adaptive learning, and dynamic network growth enable stable yet plastic somatosensory representation for human grip force control. Implications for the design of strong artificial intelligence in robotics are brought forward.

Precise measurements of muon angular distributions in zenith angle interval from 60 to 90 degrees have been performed. In total, more than 20 million muons are selected. Dependences of the absolute integral muon intensity on zenith angle for several threshold energies ranging from 1.7 GeV to 7.2 GeV are derived. Results for this region of zenith angles and threshold energies have been obtained for the first time. The dependence of integral intensity on zenith angle and threshold energy is well fitted by a simple analytical formula.

description: The speed-up provided by quantum algorithms with respect to their classical counterparts is at the origin of scientific interest in quantum computation. However, the fundamental reasons for such a speed-up are not yet completely understood and deserve further attention. In this context, the classical simulation of quantum algorithms is a useful tool that can help us in gaining insight. Starting from the study of general conditions for classical simulation, we highlight several important differences between two non-equivalent classes of quantum algorithms. We investigate their performance under realistic conditions by quantitatively studying their resilience with respect to static noise. This latter refers to errors affecting the inital preparation of the register used to run an algorithm. We also compare the evolution of the entanglement involved in the different computational processes.

description: Over height vehicle collisions with bridges are a common occurrence throughout the world. Accidental over height collisions can cause damage to a bridge superstructure and the full extent of the structural consequences from these collisions is not yet understood. This study examines the applicability of acoustic emission and nonlinear ultrasonic testing to assess structural damage on steel girders induced by over height vehicle impact. A numerical study was conducted in Ansys Explicit Dynamics that simulated an over height truck collision on a full-scale steel girder. Parametric variables of stiffness constraints, impact velocity, and impact mass were analyzed. The resulting contact force, damaged girder shapes, and plastic deformation was studied. Experimental studies on A572 Gr. 50 steel coupons were evaluated with acoustic emission and nonlinear ultrasonic testing. These studies provided data on the quantity of plastic deformation that could be detected using NLUT and AE characteristics from impact. Tensile testing was completed on ten steel coupons to specified elongations. Prior to tensile testing, the coupon samples were stress relieved in a furnace and developed an oxide layer. AE testing was performed in-situ on samples with and without the oxide layer. Distinct changes in acoustic emission energy were correlated to elastic and plastic deformation. Oxide layer breakage characteristics were analyzed using PCA clustering. NLUT and Rockwell B hardness testing was performed before and after tensile testing. Higher harmonics were observed during the nonlinear ultrasonic testing and acoustic nonlinearity parameters were found to increase with increasing plastic deformation. The third harmonic acoustic nonlinearity parameter was especially responsive to plastic deformation. Metallography on the samples was performed and an analysis of the increasing grain elongation with strain was conducted. To study acoustic emission response to impact, an impact test was completed on a steel beam using an impulse hammer and acoustic emission in-situ. A correlation between AE characteristics from impact and structural response was discussed. Plastic strain on the girder from the numerical simulations was found to be above a detectable threshold determined from the NLUT experimental results. Critical areas for inspection of the girder were identified from the numerical model.

description: We present a microlensing analysis of updated light curves in three filters, $g$--band, $r$--band, and $H$--band, for the gravitationally lensed quasars Q0957+561 and SBS0909+532. Both systems display prominent microlensing features which we analyze using our Bayesian Monte Carlo technique to constrain the quasar continuum emission region sizes in each band. We report sizes as half-light radii scaled to a 60 degree inclination angle. For Q0957+561 we measure $\log{(r_{1/2}/\text{cm})} = 16.54^{+0.33}_{-0.33}$, $16.66^{+0.37}_{-0.62}$, and $17.37^{+0.49}_{-0.40}$ in $g$--, $r$--, and $H$--band respectively. For SBS0909+532 we measure $\log{(r_{1/2}/\text{cm})} = 15.83^{+0.33}_{-0.33}$, $16.21^{+0.37}_{-0.62}$, and $17.90^{+0.61}_{-0.63}$ in $g$--, $r$--, and $H$--band respectively. With size measurements in three bands spanning the quasar rest frame ultraviolet to optical, we can place constraints on the scaling of accretion disk size with wavelength, $r\proptoλ^{1/β}$. In a joint analysis of both systems we find a slope shallower than that predicted by thin disk theory, $β= 0.35^{+0.16}_{-0.08}$, consistent with other constraints from multi-epoch microlensing studies.

Universality classes of matrix models in 4-έ dimensions
Creators: name: Jaimungal, Sebastian
Publisher: name: University of British Columbia
Year: 2009

description: The role that matrix models, in (4-έ) dimensions, play in quantum critical phenomena is explored. We begin with a traceless Hermitean scalar matrix model and add operators that couple to fermions, and gauge fields. Through each stage of generalization the universality class of the resulting theory is explored. We also argue that chiral symmetry breaking in (2 + 1) dimensional Q C D can be identified with Neel ordering in two dimensional quantum antiferromagents. When operators that drive the phase transition are added to these theories, we postulate that the resulting quantum critical behavior lies in the universality class of gauged Yukawa matrix models. As a consequence of the phase structure of this matrix model, the chiral transition is typically of first order with computable critical exponents.

We show that the inverse metric is additively separable after multiplication by a simple function. This allows us to separate the Hamilton-Jacobi equation, showing that geodesic motion is integrable on this background. The separation of the Hamilton-Jacobi equation is intimately linked to the existence of an irreducible Killing tensor, which provides an extra constant of motion. We also demonstrate that the Klein-Gordon equation for this background is separable.

In this paper we present a method to take into account, at the symbolic level, that an intruder actively attacking a protocol execution may use these collision algorithms in reasonable time during the attack. Our decision procedure relies on the reduction of constraint solving for an intruder exploiting the collision properties of hush functions to constraint solving for an intruder operating on words.
Utilizing Business Process Re-Engineering for Optimization Of A Third Party Logistics Company
Creators: name: Ajitesh Das

Subjects: Uncategorized

description: Purpose: Third Party logistics(3PLs) have become a critical component in the supply chains. Thus; for a 3PL to function in a dynamic and competitive environment, it needs to have business processes that cater to such an environment. As per the theory of business process reengineering, any process is a viable candidate for reengineering. This master’s thesis is aimed at identifying the business processes that need reengineering for Blue-Grace logistics a third party logistics firm located in Chicago. Design/Methodologies/Approach: To carry out any form of reengineering, it is imperative to first find out the present state of the business processes in a facility. To achieve this, a swim lane process map has been utilized. This is the very first step towards identifying the various processes and the people involved with it. The next step is to find what are the processes that are ‘most’ broken. To achieve this, a survey was administered to the workers to get their opinions on what they think needs immediate attention. Having identified a potential process, the next step is to get metrics used by the firm to measure their processes or the data collection phase. These metrics can then be used to recreate a dynamic model of the process. In this case, two models were developed at two stages. The first case utilized the principles of process mining to recreate the process from a strategic level. Thereafter, a discrete event simulation was used to further drill down to an operational level. Additionally, a task analysis was used to examine how the current environment seemed to affect the productivity levels of employees. Findings: After application of the above-mentioned methodology, the process that required the most attention was the process of booking carriers for loads. The need for approving loads by a carrier manager was found to be necessary for change. Carrier representatives needed more autonomy when it came to approving loads. A mechanism was then created based upon data of the firm to help them achieve this. Additionally, the survey revealed that the inhouse I.T. system was found to lag often. Employees reported of disturbance due to their immediate vicinity and the absence of ergonomically friendly furniture to affect their productivity at work. The efficacy of the solutions proposed were quantified by using a cost-benefit calculator related to human productivity measurement, developed at Washington State University.

description: We show that the trigonometric solitons of the KP hierarchy enjoy a differential-difference bispectral property, which becomes transparent when translated on two suitable spaces of pairs of matrices satisfying certain rank one conditions. The result can be seen as a non-self-dual illustration of Wilson's fundamental idea [Invent. Math. 133 (1998), 1-41] for understanding the (self-dual) bispectral property of the rational solutions of the KP hierarchy. It also gives a bispectral interpretation of a (dynamical) duality between the hyperbolic Calogero-Moser system and the rational Ruijsenaars-Schneider system, which was first observed by Ruijsenaars [Comm. Math. Phys. 115 (1988), 127-165].

description: Embodied human communication encompasses both verbal (speech) and non-verbal information (e.g., gesture and head movements). Recent advances in machine learning have substantially improved the technologies for generating synthetic versions of both of these types of data: On the speech side, text-to-speech systems are now able to generate highly convincing, spontaneous-sounding speech using unscripted speech audio as the source material. On the motion side, probabilistic motion-generation methods can now synthesise vivid and lifelike speech-driven 3D gesticulation. In this paper, we put these two state-of-the-art technologies together in a coherent fashion for the first time. Concretely, we demonstrate a proof-of-concept system trained on a single-speaker audio and motion-capture dataset, that is able to generate both speech and full-body gestures together from text input. In contrast to previous approaches for joint speech-and-gesture generation, we generate full-body gestures from speech synthesis trained on recordings of spontaneous speech from the same person as the motion-capture data. We illustrate our results by visualising gesture spaces and text-speech-gesture alignments, and through a demonstration video at https://simonalexanderson.github.io/IVA2020 .

Structure formation on the brane: A mimicry

description: We show how braneworld cosmology with bulk matter can explain structure formation. In this scenario, the nonlocal corrections to the Friedmann equations supply a Weyl fluid that can dominate over matter at late times due to the energy exchange between the brane and the bulk. We demonstrate that the presence of the Weyl fluid radically changes the perturbation equations, which can take care of the fluctuations required to account for the large amount of inhomogeneities observed in the local universe. Further, we show how this Weyl fluid can mimic dark matter. We also investigate the bulk geometry responsible for the scenario.

description: We have studied low-frequency (45 - 410 MHz) type III solar radio bursts observed using the e-CALLISTO spectrometer located at Gauribidanur radio observatory, India during 2013 - 2017. After inspecting the 1531 type III bursts we found that 426 bursts were associated with flares, while the other bursts might have triggered by small scale features / weak energy events present in the solar corona. In this study, we have carried out a statistical analysis of various observational parameters like start time, lower and upper-frequency cut-offs of type III bursts and their association with flares, variation of such parameters with flare parameters such as location, class, onset and peak timings. From this study, we found that most of the high-frequency bursts (whose upper-frequency cut-off $> 350$ MHz) are originated from the western longitudes. We interpret that it could be due to the fact that Parker spirals from these longitudes are directed towards the earth and high-frequency bursts are more directive. Further, we report that number of bursts that reach earth from western longitudes are higher than eastern longitudes.

description: We present the application of a novel method of time-series analysis, the Hilbert-Huang Transform, to the search for gravitational waves. This algorithm is adaptive and does not impose a basis set on the data, and thus the time-frequency decomposition it provides is not limited by time-frequency uncertainty spreading. Because of its high time-frequency resolution it has important applications to both signal detection and instrumental characterization. Applications to the data analysis of the ground and space based gravitational wave detectors, LIGO and LISA, are described.
The Relationship between Domain-Specific Identity and Moral Conviction
Creators: name: Keeran, Lindsay
Publisher: name: University of Illinois at Chicago
Year: 2020
Subjects: Uncategorized

description: The current research investigated identity as a possible motivator of moral conviction by directly comparing how much people reported that their attitudes were reflections of personal identity versus social identity (i.e. “domain-specific identity”) predicted the degree to which they also reported that these attitudes were moral convictions. Across two studies, domain-specific personal identity uniquely predicted moral conviction, but domain-specific social identity did not. This result held across different issues and after controlling for a variety of covariates. The results also did not vary as a function of individualistic versus collectivistic mindset (Study 2). Findings are discussed in terms of their relevance for explaining certain aspects of moral conviction (given a relationship with domain-specific personal identity), as well as implications for moralization processes and buffering threats to the self.
The study of leading twist light cone wave functions of J/Psi meson

Publisher: name: arXiv
Year: 2007
Subjects: subject: High Energy Physics - Phenomenology (hep-ph)
subject: FOS: Physical sciences

description: This paper is devoted to the study of leading twist light cone wave functions of J/Psi meson. The moments of these wave functions have been calculated within three approaches: potential models, nonrelativistic QCD and QCD sum rules. Using the results obtained within these approaches the models for the light cone wave functions of leading twist have been proposed. Similarly to the wave function of eta_c meson the leading twist light cone wave functions of J/Psi meson have very interesting properties at scales greater than m_c: improvement of the accuracy of the model, appearance of relativistic tail and violation of nonrelativistic QCD velocity scaling rules. The last two properties are the properties of true leading twist light cone wave functions of J/Psi meson.

description: The formation of hot stars out of the cold interstellar medium lies at the heart of astrophysical research. Understanding the importance of magnetic fields during star formation remains a major challenge. With the advent of the Atacama Large Millimeter Array, the potential to study magnetic fields by polarization observations has tremendously progressed. However, the major question remains how much magnetic fields shape the star formation process or whether gravity is largely dominating. Here, we show that for the high-mass star-forming region G327.3 the magnetic field morphology appears to be dominantly shaped by the gravitational contraction of the central massive gas core where the star formation proceeds. We find that in the outer parts of the region, the magnetic field is directed toward the gravitational center of the region. Filamentary structures feeding the central core exhibit U-shaped magnetic field morphologies directed toward the gravitational center as well, again showing the gravitational drag toward the center. The inner part then shows rotational signatures, potentially associated with an embedded disk, and there the magnetic field morphology appears to be rotationally dominated. Hence, our results demonstrate that for this region gravity and rotation are dominating the dynamics and shaping the magnetic field morphology.

description: In this article we combine the projective Landweber method, recently proposed by the authors, with Kaczmarz's method for solving systems of non-linear ill-posed equations. The underlying assumption used in this work is the tangential cone condition. We show that the proposed iteration is a convergent regularization method. Numerical tests are presented for a non-linear inverse problem related to the Dirichlet-to-Neumann map, indicating a superior performance of the proposed method when compared with other well established iterations. Our preliminary investigation indicates that the resulting iteration is a promising alternative for computing stable solutions of large scale systems of nonlinear ill-posed equations.
