description: Deep matrix factorizations (deep MFs) are recent unsupervised data mining techniques inspired by constrained low-rank approximations. They aim to extract complex hierarchies of features within high-dimensional datasets. Most of the loss functions proposed in the literature to evaluate the quality of deep MF models and the underlying optimization frameworks are not consistent because different losses are used at different layers. In this paper, we introduce two meaningful loss functions for deep MF and present a generic framework to solve the corresponding optimization problems. We illustrate the effectiveness of this approach through the integration of various constraints and regularizations, such as sparsity, nonnegativity and minimum-volume. The models are successfully applied on both synthetic and real data, namely for hyperspectral unmixing and extraction of facial features.

description: We present spectroscopic and photometric observations for the Type Ibn supernova (SN) dubbed PSN J07285387+3349106. Using data provided by amateur astronomers, we monitored the photometric rise of the SN to maximum light, occurred on 2015 February 18.8 UT (JD(max,V) = 2457072.0 +- 0.8). PSN J07285387+3349106 exploded in the inner region of an infrared luminous galaxy, and is the most reddened SN Ibn discovered so far. We apply multiple methods to derive the total reddening to the SN, and determine a total colour excess E(B-V)(tot) = 0.99 +- 0.48 mag. Accounting for the reddening correction, which is affected by a large uncertainty, we estimate a peak absolute magnitude of M(V) = -20.30 +- 1.50. The spectra are dominated by continuum emission at early phases, and He I lines with narrow P-Cygni profiles are detected. We also identify weak Fe III and N II features. All these lines show an absorption component which is blue-shifted by about 900-1000 km/s. The spectra also show relatively broad He I line wings with low contrast, which extend to above 3000 km/s. From about 2 weeks past maximum, broad lines of O I, Mg II and the Ca II near-infrared triplet are identified. The composition and the expansion velocity of the circumstellar material, and the presence of He I and alpha-elements in the SN ejecta indicate that PSN J07285387+3349106 was produced by the core-collapse of a stripped-envelope star. We suggest that the precursor was WNE-type Wolf-Rayet star in its dense, He-rich circumstellar cocoon.

description: We study $SU(2)$ gauge theories coupled to $(A_1,D_N)$ theories with or without a fundamental hypermultiplet. For even $N$, a formula for the contribution of $(A_1,D_N)$ to the Nekrasov partition function was recently obtained by us with Y.~Sugawara and T.~Uetoko. In this paper, we generalize it to the case of odd $N$ in the classical limit, under the condition that the relevant couplings and vacuum expectation values of Coulomb branch operators of $(A_1,D_N)$ are all turned off. We apply our formula to the $(A_2,A_5)$ theory to find that its prepotential is related to that of the $SU(2)$ gauge theory with four fundamental flavors by a simple change of variables.

The importance of employee motivation, engagement, and empowerment in healthcare: Case study on the Lehigh Valley Super Utilizer Partnership
Creators: name: de la Cruz, Yuriko
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 2015

description: Research conducted to examine the role of employee motivation, engagement, and empowerment on the overall success of organizations demonstrates how critical it is for managers and leaders to implement strategies to improve employee motivation, engagement, and empowerment. This is especially true in healthcare where these efforts have an impact on internal (staff) and external customers (patients and the community). However, many organizations experience significant challenges with employee motivation, engagement, and empowerment which result in high levels of staff turnover, staff absenteeism, low levels of staff morale, and high costs related to filling vacancies while experiencing lower levels of productivity. Left unaddressed, these issues worsen over time and affect patient safety and health outcomes. This is especially important for healthcare providers that work with highly vulnerable populations, such as the Lehigh Valley Super Utilizer Partnership (LVSUP) in Allentown, PA, which works with patients that have multiple, chronic health conditions and have super utilization of healthcare services. The purpose of this paper is to provide an overview of employee motivation, engagement, and empowerment and its implication in healthcare, and to use LVSUP as a case study to describe strategies used by LVSUP to address their challenges with these important issues. The paper discusses the implications of the strategies used by LVSUP within the context of healthcare coordination as well as the general field of public health. Because of the strategies used by LVSUP to address their challenges, it resulted in improved team cohesiveness and greater participation from LVSUP staff and partners during the decision-making process, when providing feedback on improving patient care coordination, and when offering recommendations to improve internal work processes. What this research and the LVSUP case study have shown is that managers and leaders must implement strategies to create an empowered workforce along with a positive workplace environment that allows staff to be highly motivated, engaged, and innovative. As a result, teams of empowered staff will be able to achieve desired results and overcome complex challenges within the dynamic landscape of public health and healthcare systems.

description: The epoch in which galactic discs settle and secular evolution takes place is a major benchmark to test models of galaxy formation and evolution. Yet, this epoch is still largely unknown. Once discs settle and become self-gravitating enough, stellar bars are able to form and act on the evolution of the host galaxy; therefore, determining the ages of bars can shed light on the epoch of disc settling, and on the onset of secular evolution. Nevertheless, until now, timing when bars in nearby galaxies have formed has proven challenging. In this talk, I will present a new methodology for obtaining the bar age together with the first results. In particular, we use integral field spectroscopic (IFS) data from the TIMER survey to disentangle the light of the central region of galaxies and derive independent star formation histories. Since the bar gravitational torques bring gas inwards, it builds nuclear structures that can be used to time when the bar itself formed. I will present the first results of this methodology for the TIMER sample, including the old bar hosted by NGC1433, with an estimated age of 7.5 Gyrs. Additionally, I will present preliminary results showing that bars can be young and recently formed, discs can still be settling in the Local Universe, and how these galaxies compared to the Milky Way. This methodology is applicable to high-resolution IFS data of barred galaxies with bar-built nuclear structures. Thus, in the future we will be able to determine the bar age for a large sample of galaxies, shedding light on the epoch of disc settling and bar formation as a function of stellar mass and other galactic properties.

description: Normalizing the recent LHCb measurement of $Λ_b \to Λ_c τ\barν$ to the standard model (SM) prediction for the $Λ_b \to Λ_c μ\barν$ rate, instead of a LEP measurement, provides a more consistent comparison with the SM prediction for the lepton flavor universality ratio $R(Λ_c)$. This modestly increases $R(Λ_c)$ compared to the quoted LHCb result, such that it no longer hints at a suppression compared to the SM, which would be hard to accommodate in new physics scenarios that enhance $R(D^{(*)})$. We point out that the fraction of excited states in inclusive semileptonic $Λ_b$ decay may be significantly greater than the corresponding fraction in $B$ decays. Possible implications are speculated upon.

The Role of Primary Care in Early Childhood Developmental Screening
Creators: name: Beed, Margaret
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 2009

description: Most children experience routine well child visits to health care practitioners, primarily pediatricians, family practitioners, and advanced nurse practitioners. There is a relatively standardized agenda for well child visits. In addition to immunizations and screening for disease, these visits have a stated purpose of monitoring growth and development. It would seem that following a child’s development would be a priority. Any delays or issues related to abnormal development should be identified early. Parents need to either be reassured that all is proceeding normally, or efficiently directed towards resources devoted to diagnosis and treatment. Nevertheless, most children with developmental problems are not identified until school entry. Monitoring development is not as straightforward as monitoring height, weight, BMI and head circumference as a person matures. Many pediatricians use an informal process of observation and parental reporting to follow development. Although pediatricians may feel that their current processes of early identification are sufficient, more formal screening is needed at defined ages. A number of reliable and valid screening instruments, each with their own strengths and weaknesses, are available. Research has determined that screening tools, as used in clinical practice, are sufficiently sensitive to be useful when applied to populations. A variety of pilot efforts have shown that population screening is feasible, and that increases above baseline screening rates are possible. Early intervention has been shown to reduce the negative and expensive outcomes related to pregnancy, occupational success and incarceration. Although obstacles and objections to screening exist, the prevalence, ability to screen, and need for early intervention make a strong argument for developmental screening to be among a health system’s priorities. Even in an era of limited resources, a program of improving the health care system’s ability to screen, diagnose and treat developmental problems represents a use of resources that is a good value for society.

description: The strong non-linear increase in Cu interconnect line resistance with a decrease in linewidth presents a significant obstacle to their continued downscaling. In this letter we use first principles density functional theory based electronic structure of Cu interconnects to find the lower limits of their line resistance for metal linewidths corresponding to future technology nodes. We find that even in the absence of scattering due to grain boundaries, edge roughness or interfaces, quantum confinement causes a severe reduction in current carrying capacity of Cu. We discuss the causes of transport orientation dependent anisotropy of quantum confinement in Cu. We also find that when the simplest scattering mechanism in the grain boundary scattering dominated limit is added to otherwise coherent electronic transmission in monocrystalline nanowires, the lower limits of line resistance are significantly higher than projected roadmap requirements in the International Technology Roadmap for Semiconductors.

description: We present a generalisation of the all-Mach solver of Fuster & Popinet (2018) to account for heat diffusion between two different compressible phases. By solving a two-way coupled system of equations for pressure and temperature, the current code is shown to increase the robustness and accuracy of the solver with respect to classical explicit discretization schemes. Different test cases are proposed to validate the implementation of the thermal effects: an Epstein-Plesset like problem for temperature is shown to compare well with a spectral method solution. The code also reproduces free small amplitude oscillations of a spherical bubble where analytical solutions capturing the transition between isothermal and adiabatic regimes are available. We show results of a single sonoluminescent bubble (SBSL) in standing waves, where the result of the DNS is compared with that of other methods in the literature. Moreover, the Rayleigh collapse problem is studied in order to evaluate the importance of thermal effects on the peak pressures reached during the collapse of spherical bubbles. Finally, the collapse of a bubble near a rigid boundary is studied reporting the change of heat flux as a function of the stand-off distance.

description: The SDO mission has been collecting solar data for the past 13 years, producing a large dataset measured in the order of tens of petabytes. Such an immense dataset now contains information beyond that of an entire solar cycle, making it extremely valuable to the heliophysics community, and can be used for critical tasks such as space weather analysis and forecasting. However, getting access to all of this data can be challenging. In an attempt to overcome the challenges associated with the management of this incredible amount of data, we successfully created a scientific computing platform, which we are now open-sourcing. There are several reasons why access to SDO data is difficult, but they may stem from a lack of existing data infrastructure to allow researchers easy access to the dataset. As part of the 2023 FDL-X Helio challenge, we have developed a data pipeline to ingest and transform this data into a readily available, and complete data product. Using Google Cloud Platform (GCP), we host the entire 13 years of AIA and HMI data with a 6 and 12-minute cadence respectively, in 512x512 resolution. We also calibrate the AIA data up to level 1.5 and the HMI images presented as (x, y, z) components of the magnetic field. Furthermore, the data has been curated so that the solar disk appears the same size in each image, making the data machine-learning ready. We will present both our data infrastructure and the data product “SDOMLv2”, as well as discuss how we egressed the 13 years of data efficiently from its storage in JSOC. We will also discuss how our approach is generalizable and may be adopted in other scientific domains.

Subjects: subject: Materials Science (cond-mat.mtrl-sci)

description: A thermodynamically consistent multiphase phase-field approach for stress and temperature-induced martensitic phase transformation at the nanoscale and under large strains is developed. A total of N independent order parameters are considered for materials with N variants, where one of the order parameters describes A <-> M transformations and the remaining N-1 independent order parameters describe the transformations between the variants. A non-contradictory gradient energy is used within the free energy of the system to account for the energies of the interfaces. In addition, a non-contradictory kinetic relationships for the rate of the order parameters versus thermodynamic driving forces is suggested. As a result, a system of consistent coupled Ginzburg-Landau equations for the order parameters are derived. The crystallographic solution for twins within twins is presented for the cubic to tetragonal transformations. A 3D complex twins within twins microstructure is simulated using the developed phase-field approach and a large-strain-based nonlinear finite element method. A comparative study between the crystallographic solution and the simulation result is presented.

description: Consider analytic generic unfoldings of the three dimensional conservative Hopf-Zero singularity. Under open conditions on the parameters determining the singularity, the unfolding possesses two saddle-foci when the unfolding parameter is small enough. One of them has one dimensional stable manifold and two dimensional unstable manifold whereas the other one has one dimensional unstable manifold and two dimensional stable manifold. Baldomá, Castejón and Seara [BCS13] gave an asymptotic formula for the distance between the one dimensional invariant manifolds in a suitable transverse section. This distance is exponentially small with respect to the perturbative parameter, and it depends on what is usually called a Stokes constant. The non-vanishing of this constant implies that the distance between the invariant manifolds at the section is not zero. However, up to now there do not exist analytic techniques to check that condition. In this paper we provide a method for obtaining accurate rigorous computer assisted bounds for the Stokes constant. We apply it to two concrete unfoldings of the Hopf-Zero singularity, obtaining a computer assisted proof that the constant is non-zero.

description: Future transportation and a system-wide adoption of electric mobility highly depend on the capacity and ubiquity of the charging infrastructure. To assure a level of electricity supply that is sufficient to meet the recharge demand, we need realistic demand estimates taking socio-economic conditions into account. To address this need, we developed an agent-based modelling framework that determines the spatiotemporal distribution of electric vehicle charging demand considering commuting behaviour and accompanying charging needs of individuals, and reports the results in a detailed as well as aggregated manner. The framework is implemented as open-source software that can be used to simulate various scenarios in a scalable manner starting from the city level up to the country level.

description: Multiple-input multiple-output (MIMO) systems with a large number of basestation antennas, often called massive MIMO, have received much attention in academia and industry as a means to improve the spectral efficiency, energy efficiency, and processing complexity of next generation cellular system. Mobile communication industry has initiated a feasibility study of massive MIMO systems to meet the increasing demand of future wireless systems. Field trials of the proof-of-concept systems have demonstrated the potential gain of the Full-Dimension MIMO (FD-MIMO), an official name for the MIMO enhancement in 3rd generation partnership project (3GPP). 3GPP initiated standardization activity for the seamless integration of this technology into current 4G LTE systems. In this article, we provide an overview of the FD-MIMO system, with emphasis on the discussion and debate conducted on the standardization process of Release 13. We present key features for FD-MIMO systems, a summary of the major issues for the standardization and practical system design, and performance evaluations for typical FD-MIMO scenarios.

description: The Drug Addiction Treatment Act allows physicians to prescribe buprenorphine-naloxone in the office, but the effectiveness of providing this medication is not fully established, particularly for primary care-relevant outcomes. In this retrospective chart review of 82 patients receiving buprenorphine-naloxone in a University of North Carolina-affiliated primary care clinic between April 6th, 2011 and February 1st, 2017, data regarding comorbidity screening, comorbidity treatment rates, and emergency department utilization were collected. Comparing patients retained at one year to those lost to follow-up, screening, diagnosis, and treatment rates were evaluated for six USPSTF-recommended comorbidities. Overall screening quality was established by identifying proportions of patients receiving ≥80% of eligible services. Trends in PHQ-9 scores and emergency department visits before and after one year of treatment were analyzed. Overall, 72% of patients were retained at one year. Screening rates for comorbidities—both singular and composite—were high in both groups with non-significant differences. About 17% of patients from the retained group and 13% of the group lost to follow-up received a new comorbidity diagnosis with high treatment rates for HIV and hypertension in both groups. PHQ-9 scores decreased by one point on average (p=0.287). Emergency department visits were also lower at one year (median difference =1 visit, p<0.001) with no differences observed in those lost to follow-up (p=0.78). One-year retention on office-based buprenorphine-naloxone appears beneficial to patients in regards to comorbidity screening and management and decreased emergency department use. Office-based opioid treatment is a unique opportunity to provide comprehensive care to a set of high-risk patients and, therefore, outcomes relevant to dispensing such care should be utilized in future research.

description: Does social categorization influence moral assessments? Subjects responded to vignettes in which actors with gendered names or gendered traits were the victim or perpetrator of wrongdoing. Men and stereotype-incongruent women were ascribed greater responsibility (blame, punishment) for wrongdoing, while “traditional” women were ascribed greater considerability (concern, protection) as victims.

description: Matrix factorization (MS) is a collaborative filtering (CF) based approach, which is widely used for recommendation systems (RS). In this research work, we deal with the content recommendation problem for users in a content management system (CMS) based on users' feedback data. The CMS is applied for publishing and pushing curated content to the employees of a company or an organization. Here, we have used the user's feedback data and content data to solve the content recommendation problem. We prepare individual user profiles and then generate recommendation results based on different categories, including Direct Interaction, Social Share, and Reading Statistics, of user's feedback data. Subsequently, we analyze the effect of the different categories on the recommendation results. The results have shown that different categories of feedback data have different impacts on recommendation accuracy. The best performance achieves if we include all types of data for the recommendation task. We also incorporate content similarity as a regularization term into an MF model for designing a hybrid model. Experimental results have shown that the proposed hybrid model demonstrates better performance compared with the traditional MF-based models.
Optimal quantum control via genetic algorithms for quantum state engineering in driven-resonator mediated networks

description: We employ a machine learning-enabled approach to quantum state engineering based on evolutionary algorithms. In particular, we focus on superconducting platforms and consider a network of qubits -- encoded in the states of artificial atoms with no direct coupling -- interacting via a common single-mode driven microwave resonator. The qubit-resonator couplings are assumed to be in the resonant regime and tunable in time. A genetic algorithm is used in order to find the functional time-dependence of the couplings that optimise the fidelity between the evolved state and a variety of targets, including three-qubit GHZ and Dicke states and four-qubit graph states. We observe high quantum fidelities (above 0.96 in the worst case setting of a system of effective dimension 96) and resilience to noise, despite the algorithm being trained in the ideal noise-free setting. These results show that the genetic algorithms represent an effective approach to control quantum systems of large dimensions.

description: In the present article a new class of exact solutions of Einstein's field equations for charged anisotropic distribution is obtained on the background of pseudo-spheroidal spacetime characterized by the metric potential $g_{rr}=\frac{1+K\frac{r^2}{R^2}}{1+\frac{r^2}{R^2}}$, where $K$ and $R$ are geometric parameters of the spacetime. The radial pressure $p_r$ and electric field intensity $E$ are taken in the form $8πp_r = \frac{K-1}{R^2}\frac{\left(1-\frac{r^2}{R^2} \right)}{\left(1+K\frac{r^2}{R^2} \right)^2}$ and $E^2 = \frac{α(K-1)\frac{r^2}{R^2}}{R^2\left(1+K\frac{r^2}{R^2} \right)^2}$. The bounds of geometric parameter $K$ and the parameter $α$ appearing in the expression of $E^2$ are obtained by imposing the requirements for a physically acceptable model. It is found that the model is in good agreement with the observational data of number of compact stars like 4U 1820-30, PSR J1903+327, 4U 1608-52, Vela X-1, PSR J1614-2230, Cen X-3 given by Gangopadhyay {\em{et al}} [Gangopadhyay T., Ray S., Li X-D., Dey J. and Dey M., {\it Mon. Not. R. Astron. Soc.} {\bf431} (2013) 3216]. When $α= 0$, the model reduces to the uncharged anisotropic distribution given by Ratanpal {\em et al.} [Ratanpal B. S., Thomas V. O. and Pandya D. M., arXiv:1506.08512 [gr-qc](2015)]

description: After decades of research, recent laser-driven inertial fusion experiments have demonstrated rapid progress toward achieving thermonuclear ignition using capsule designs with cryogenic fuel layers. The ignition physics for these layered capsules involves a complex interplay between the dynamically forming hot spot and the dense surrounding fuel. Using analytic theory and numerical simulations, we demonstrate that the mass ablation rate into the hot spot depends sensitively upon the temperature of the dense fuel, resulting in ablative inflows up to ~4x faster than previous estimates. This produces an enthalpy flux into the hot spot that plays a critical role in controlling the hot spot temperature, the ignition threshold, and the subsequent burn propagation. The net influence of mass ablation on the ignition threshold is regulated by a dimensionless parameter that depends upon the temperature of the dense fuel. As a consequence, the ignition threshold is sensitive to any mechanism that heats the dense fuel, such as neutrons or radiation emitted from the hot spot. These predictions are confirmed using radiation hydrodynamic simulations for a series of capsules near ignition conditions. This analysis may have relevance for understanding the variable performance of recent experiments and for guiding new capsule designs toward higher fusion yields.

description: Transient noise glitches in gravitational-wave detector data limit the sensitivity of searches and contaminate detected signals. In this Paper, we show how glitches can be simulated using generative adversarial networks. We produce hundreds of synthetic images for the 22 most common types of glitches seen in the LIGO, KAGRA, and Virgo detectors. The artificial glitches can be used to improve the performance of searches and parameter-estimation algorithms. We perform a neural network classification to show that our artificial glitches are an excellent match for real glitches, with an average classification accuracy across all 22 glitch types of 99.0%.
