description: We present spatially resolved stellar and/or ionized gas kinematic properties for a sample of 103 interacting galaxies, tracing all merger stages: close companions, pairs with morphological signatures of interaction, and coalesced merger remnants. We compare our sample with 80 non-interacting galaxies. We measure for the stellar and the ionized gas components the major (projected) kinematic position angles (PA$_{\mathrm{kin}}$, approaching and receding) directly from the velocity fields with no assumptions on the internal motions. This method allow us to derive the deviations of the kinematic PAs from a straight line ($δ$PA$_{\mathrm{kin}}$). Around half of the interacting objects show morpho-kinematic PA misalignments that cannot be found in the control sample. Those misalignments are present mostly in galaxies with morphological signatures of interaction. Alignment between the kinematic sides for both samples is similar, with most of the galaxies displaying small misalignments. Radial deviations of the kinematic PA from a straight line in the stellar component measured by $δ$PA$_{\mathrm{kin}}$ are large for both samples. However, for a large fraction of interacting galaxies the ionized gas $δ$PA$_{\mathrm{kin}}$ is larger than typical values derived from isolated galaxies (48%), making this parameter a good indicator to trace the impact of interaction and mergers in the internal motions of galaxies. By comparing the stellar and ionized gas kinematic PA, we find that 42% (28/66) of the interacting galaxies have misalignments larger than 16 degrees, compared to 10% from the control sample. Our results show the impact of interactions in the internal structure of galaxies as well as the wide variety of their velocity distributions. This study also provides a local Universe benchmark for kinematic studies in merging galaxies at high redshift.

description: In a panel discussion on the impact of cooperating in networks to achieve impact and to enable change, Roeland Ordelman, CTO of CLARIAH, reflects on network collaboration in CLARIAH. The session took place during the World Library and Information Congress IFLA2023, on Tuesday 22nd of August 2023, hosted by the National Committee of the Netherlands. Several participants presented examples of how they form, facilitate and strengthen networks in their respective fields in order to battle the complex societal challenges. The goal of the session was to show that it is possible to cooperate in this way, but that it requires fundamental different ways of working, organising and sharing responsibility. It requires fundamental new leadership.
The Existing and Escalating Public Health Threat of Antibiotic Resistance

Year: 2014

description: Antibiotics have been hailed as one of the greatest public health achievements of the 20th century, and are a stalwart component of modern medicine. The discovery of penicillin by Alexander Fleming in 1929 initiated a period of prolific research and development, in which bacterial infections that had previously cut short the lives of scores of infants and adults, were halted in their tracks by the power of these new miracle drugs. Antibiotics have been credited with saving millions of lives, but the once nearly invincible power of this miracle drug is in jeopardy, as a multitude of contributing factors have weakened their efficacy to treat many infections. To stem the established and intensifying threat of antibiotic resistance, leadership is required from public health entities and the sustained commitment and actions of numerous and varied stakeholders.

description: Il cambiamento climatico sta avendo un enorme impatto sul settore vitivinicolo. Il riscaldamento globale, in combinazione con la variazione dell’andamento pluviometrico e con l’incremento della frequenza degli eventi meteorologici estremi, sta influenzando in modo significativo la fisiologia delle piante di vite (fenologia, maturazione dell’uva, ecc.) esponendole sempre più a stress di tipo biotico ed abiotico. Questa condizione rappresenta una sfida per i viticoltori che sono chiamati sempre più spesso a prendere decisioni complesse per adattare le tecnica di gestione del vigneto e raggiungere gli obiettivi enologici prestabiliti. Questo spesso si traduce in un indesiderato incremento dell’impiego di concimi e pesticidi, nella perdita di produzione ed in una variazione della composizione dell’uva alla raccolta con un impatto negativo sulla sostenibilità del vigneto. VITIGEOSS è un progetto finanziato dall’Unione Europea nell’ambito del programma di ricerca ed innovazione Horizon2020 che ha come obiettivo lo sviluppo di soluzioni innovative di gestione del vigneto in grado di ottimizzare, tramite Sistemi di Supporto alla Decisione (DSS), la sostenibilità dell’azienda vitivinicola. Il progetto ha sviluppato strumenti, disponibili in un’unica piattaforma, che sfruttano l’impiego dei programmi satellitari GEOSS e Copernicus e di sensori di prossimità. La piattaforma VITIGEOSS, che è stata calibrata e validata in tre siti sperimentali (Italia Portogallo, Spagna), include i seguenti cinque servizi: (i) “Weather and climate forecast”, (ii) “Phenological monitoring and prediction/forecasting”, (iii) “Crop status”, (iv) “Disease management”, (v) “Business and sustainability”.

description: We study generic two-dimensional dilaton gravity with a Maxwell field and prove its triviality for constant dilaton boundary conditions, despite of the appearance of a Virasoro algebra with non-zero central charge. We do this by calculating the canonical boundary charges, which turn out to be trivial, and by calculating the quantum gravity partition function, which turns out to be unity. We show that none of the following modifications changes our conclusions: looser boundary conditions, non-linear interactions of the Maxwell field with the dilaton, inclusion of higher spin fields, inclusion of generic gauge fields. Finally, we consider specifically the charged Jackiw--Teitelboim model, whose holographic study was pioneered by Hartman and Strominger, and show that it is non-trivial for certain linear dilaton boundary conditions. We calculate the entropy from the Euclidean path integral, using Wald's method and exploiting the chiral Cardy formula. The macroscopic and microscopic results for entropy agree with each other.

description: In heavy-fermion superconductor Ce$_{1-x}$Yb$_x$CoIn$_5$ system, Yb doping was reported to cause a possible change from nodal $d$-wave superconductivity to a fully gapped $d$-wave molecular superfluid of composite pairs near $x \approx$ 0.07 (nominal value $x_{nom}$ = 0.2). Here we present systematic thermal conductivity measurements on Ce$_{1-x}$Yb$_x$CoIn$_5$ ($x$ = 0.013, 0.084, and 0.163) single crystals. The observed finite residual linear term $κ_0/T$ is insensitive to Yb doping, verifying the universal heat conduction of nodal $d$-wave superconducting gap in Ce$_{1-x}$Yb$_x$CoIn$_5$. Similar universal heat conduction is also observed in CeCo(In$_{1-y}$Cd$_y$)$_5$ system. These results reveal robust nodal $d$-wave gap in CeCoIn$_5$ upon Yb or Cd doping.

description: This paper designs hybrid analog-digital channel estimation and beamforming techniques for multiuser massive multiple input multiple output (MIMO) systems with limited number of radio frequency (RF) chains. For these systems, first we design novel minimum mean square error (MMSE) hybrid analog-digital channel estimator by considering both perfect and imperfect channel covariance matrix knowledge cases. Then, we utilize the estimated channels to enable beamforming for data transmission. When the channel covariance matrices of all user equipments (UEs) are known perfectly, we show that there is a tradeoff between the training duration and throughput. Specifically, we exploit that the optimal training duration that maximizes the throughput depends on the covariance matrices of all UEs, number of RF chains and channel coherence time ($T_c$). We also show that the training time optimization problem can be formulated as a concave maximization problem {for some system parameter settings} where its global optimal solution is obtained efficiently using existing tools. In particular, when the base station equipped with $64$ antennas and $1$ RF chain is serving one single antenna UE, $T_c=128$ symbol periods ($T_s$) and signal to noise ratio of $10$dB, we have found that the optimal training durations are $4T_s$ and $20T_s$ for highly correlated and uncorrelated Rayleigh fading channel coefficients, respectively. The analytical expressions are validated by performing numerical and extensive Monte Carlo simulations.

The effect of a visual learning toolkit on quality of life and health outcomes for heart failure patients
Creators: name: Gut, Justina
Publisher: name: No Publisher Supplied
Year: 2023

description: Background and Purpose of Project: Heart failure affects over 6 million people in the United States with a predominantly older population of diagnosed patients. Acute exacerbations of heart failure are often attributed to improper self-management education leading to circulatory overload and a decreased quality of life. This project aimed to provide a simplified, visual aid toolkit to address the gap in self-care education for heart failure patients. The goal of the project was to improve health outcomes and overall heart failure-related quality of life utilizing the toolkit. Methodology: The Minnesota Living with Heart Failure Questionnaire, along with weight, shortness of breath, and peripheral edema were assessed pre- and post-intervention. Participants used the Heart Failure Self-Care Toolkit for 6 weeks to guide them in their daily heart failure self-management practices. Results: 5 out of 5 participants completed the 6-week study. The results showed that mean scores on the Minnesota Living with Heart Failure Questionnaire decreased from pre- to post-intervention, but the change was not statistically significant (p = 0.809). There were no significant differences in weight (p = 0.676), measuring weight using a scale (p = 0.444), shortness of breath (p = 0.490), or peripheral edema (p = 1.000) before and after the intervention. Only 20% of the sample reported using the toolkit most days of the week. Implications for Practice: Findings suggest that further research is necessary to evaluate the usefulness of a visual aid toolkit in improving clinical symptoms and overall heart failure-related quality of life for heart failure patients.

Policy Alternatives to the '1000 Ft Rule' Governing Syringe Exchange Programs to Prevent HIV/AIDS Among Injection Drug Users in Washington, DC
Creators: name: Wright, Zenovia
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 2011

description: Syringe exchange is an HIV prevention intervention based on the principles of harm reduction. It is intended to prevent the spread of HIV/AIDs and other blood-borne infectious diseases amongst injection drug users (IDUs) and their sexual partners. Syringe exchange programs (SEPs) accomplish these goals by allowing IDUs to exchange used injection equipment for sterile materials. As a result of their focus on prevention in large communities, SEPs meet the definition of a classic public health intervention. Despite this, SEPs are generally met with controversy and funding limitations—often at the federal and state levels. In Washington, DC, SEPs operate under the “1000ft rule”, which makes it illegal for any person to distribute needles and/or syringes for the injection of any illegal drug in any area within 1000 feet of any school (Brady Fedynyshyn, 2009). The goal of this paper is to review the 1000ft rule and provide alternatives to it while alleviating some of the controversy surrounding SEPs. The research methodology employed included a systematic review of journals, qualitative interviews, and information available on the World Wide Web. On the basis of the information obtained in this review, recommendations for policy change in D.C. include: development of a formal stakeholder coalition and educating members on the issue; removal of the 1000ft rule from the D.C. code; maximizing access to sterile injection materials; and packaging SEPs with other services such as opiod substitution therapy, antiretroviral drugs, or talk therapy, to make the intervention more palatable to opponents. This paper presents several areas that should be considered for further research including more in depth strategies for repealing the 1000ft rule, inclusion of more expert ideas for alternatives, and exploration of what has been successful in other jurisdictions facing similar challenges with implementation and garnering support of SEPs. All community based organizations (CBOs) providing syringe exchange services should be solicited for their input. Evaluation of the effectiveness of SEPs at reducing HIV incidence amongst D.C.‟s population of IDUs must be conducted and the data must be shared with the greater community as soon as possible.

HEROIC: 3D General Relativistic Radiative Postprocessor with Comptonization for Black Hole Accretion Discs

description: We describe HEROIC, an upgraded version of the relativistic radiative post-processor code HERO described in a previous paper, but which now Includes Comptonization. HEROIC models Comptonization via the Kompaneets equation, using a quadratic approximation for the source function in the short characteristics radiation solver. It employs a simple form of accelerated lambda iteration to handle regions of high scattering opacity. In addition to solving for the radiation field, HEROIC also solves for the gas temperature by applying the condition of radiative equilibrium. We present benchmarks and tests of the Comptonization module in HEROIC with simple 1D and 3D scattering problems. We also test the ability of the code to handle various relativistic effects using model atmospheres and accretion flows in a black hole space-time. We present two applications of HEROIC to general relativistic MHD simulations of accretion discs. One application is to a thin accretion disc around a black hole. We find that the gas below the photosphere in the multi-dimensional HEROIC solution is nearly isothermal, quite different from previous solutions based on 1D plane parallel atmospheres. The second application is to a geometrically thick radiation-dominated accretion disc accreting at 11 times the Eddington rate. The multi-dimensional HEROIC solution shows that, for observers who are on axis and look down the polar funnel, the isotropic equivalent luminosity could be more than ten times the Eddington limit, even though the spectrum might still look thermal and show no signs of relativistic beaming.

Prehospital Spinal Immobilization and the Backboard Quality Assessment Study
Creators: name: Peery, C. Andrew
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 2003

description: Prehospital spinal immobilization for patients with suspected spinal injury has been the universal standard of practice in the United States since the early 1970's. Recent debate has focused on the lack of strong evidence indicating improved patient outcomes as a result of this practice. This article reviews the literature regarding prehospital spinal immobilization to examine the origins of this practice, the evidence that supports it, the evidence against it, and the difficulties faced by researchers who work in the field. This article also presents the results to date of the Backboard Quality Assessment Study (BQAS), a prospective observational study to evaluate strap tightness and tape adhesion in immobilized patients arriving by ambulance at an academic medical center. To date, an evaluation of 17 subjects has found that 7 subjects ( 41%) had at least one unattached strap or piece of tape that should have attached their head to the board, while 14 subjects (82%) were found to have greater than 2 em of slack between their body and at least one strap. Among those with any straps looser than 2 em, the average number ofloose straps was 3.2 out of 4. This study suggests that many patients may not be as well immobilized as they could be given existing technology.

By employing a combination of the density function theory and quantum Monte Carlo simulation, we demonstrate such semiconductors using Mn-doped BaZn2As2, which has a band gap of 0.2 eV. In addition, we found a new non-toxic DMS Mn-doped BaZn2Sb2, of which the Curie temperature Tc is predicted to be higher than that of Mn-doped BaZn2As2, the Tc of which was up to 230 K in the recent experiment.

Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 2005

description: A cross-sectional study was conducted among 223 registered nurses in St. Thomas and St. Croix Virgin Islands to gather information about how nurses perceived occupational risks and hazards in their workplace environment. Occupational hazards are categorized as biological (e,g., HIV), chemical (e.g., antiseptics), enviromechanical (e.g. , lifting), physical (e.g., noise.), and psychosocial (e.g. , inadequate staff). Nurses cited the following major reasons they were at risk for occupational illnesses and injuries: • Unable to always predict unexpected exposures • The attitude that hazardous occupational exposures are an inevitable part of a nurse's practice • Apathy, complacency, or don't care attitude • Lack of convenience and/or time to take protective measures • Nurses lack of knowledge and understanding of their workplace hazards or/do not believe that workplace hazards really exist Factors such as shiftwork, age, and type of work were important contributors to injuries sustained. Clearly there is a need for in-service training with the staff and the induction of a trained occupational health nurse to assist with the mitigation/elimination of illnesses and injuries among nurses.

description: Stochastic neural networks such as Restricted Boltzmann Machines (RBMs) have been successfully used in applications ranging from speech recognition to image classification. Inference and learning in these algorithms use a Markov Chain Monte Carlo procedure called Gibbs sampling, where a logistic function forms the kernel of this sampler. On the other side of the spectrum, neuromorphic systems have shown great promise for low-power and parallelized cognitive computing, but lack well-suited applications and automation procedures. In this work, we propose a systematic method for bridging the RBM algorithm and digital neuromorphic systems, with a generative pattern completion task as proof of concept. For this, we first propose a method of producing the Gibbs sampler using bio-inspired digital noisy integrate-and-fire neurons. Next, we describe the process of mapping generative RBMs trained offline onto the IBM TrueNorth neurosynaptic processor -- a low-power digital neuromorphic VLSI substrate. Mapping these algorithms onto neuromorphic hardware presents unique challenges in network connectivity and weight and bias quantization, which, in turn, require architectural and design strategies for the physical realization. Generative performance metrics are analyzed to validate the neuromorphic requirements and to best select the neuron parameters for the model. Lastly, we describe a design automation procedure which achieves optimal resource usage, accounting for the novel hardware adaptations. This work represents the first implementation of generative RBM inference on a neuromorphic VLSI substrate.

What do Students Say? The Palliative Care and End of Life Care Curriculum at one U.S. Medical School
Creators: name: Johnson, Opemipo O.
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 2009

description: Background: Several researchers have highlighted the insufficiencies of the United States medical system in meeting the physical and psychological needs of dying patients. In order to address this concern, increased emphasis is being placed on enhancing exposure and improving competency in palliative and end-of-life care among undergraduate and graduate medical education. The objective of this project is to evaluate the efficacy of Duke University School of Medicine’s curricula on palliative care education by measuring the level of confidence pertaining to symptom management, communication and end-of-life-care among first, second and fourth year medical students. Methods: A one-page survey was distributed to first, second and fourth year medical students. The survey inquired about the student’s level of confidence with palliative-care symptom management, communication, and end of life care and their perceived quality of the training received. Students were asked to rate their level of confidence about each question on a range of 1 to 5, with 1 indicating a poor level of confidence and 5 indicating an excellent level of confidence. The means and SD for each question in all the classes were calculated. For each question, Ordinary Least Squares were used in estimating an omnibus 2 degree of freedom test to determine if significant differences existed amongst the three classes. Results: A total of 200 medical students responded to the survey. 33 first year medical students, 83 second year students and 84 fourth year students completed the survey. First year students reported lowest level of confidence about all three classes. Second and 4th year medical students report higher confidence with symptom management compared to communication and end-of-life care. The overall perceived quality of the palliative care and end-of-life curriculum ranged from poor to fair among all three classes. About half of the survey respondents desired additional palliative care training in the current curriculum. Conclusion: Although 2nd and 4th year medical students report moderate level of confidence with palliative care related topics, a substantial number of students desired more training in communication and care for dying patients.

description: In this paper, we solve the eigenvalues and eigenvectors problem with Bohr collective Hamil- tonian for triaxial nuclei. The ? beta part of the collective potential is taken to be equal to Hulth?en potential while the gamma part is defined by a new generalized potential obtained from a ring shaped one. Analytical expressions for spectra and wave functions are derived by means of a recent version of the asymptotic iteration method and the usual approximations. The calculated energies and B(E2) transition rates are compared with experimental data and the available theoretical results in the literature.

description: Uplink-downlink decoupling in which users can be associated to different base stations in the uplink and downlink of heterogeneous small cell networks (SCNs) has attracted significant attention recently. However, most existing works focus on simple association mechanisms in LTE SCNs that operate only in the licensed band. In contrast, in this paper, the problem of resource allocation with uplink-downlink decoupling is studied for an SCN that incorporates LTE in the unlicensed band (LTE-U). Here, the users can access both licensed and unlicensed bands while being associated to different base stations. This problem is formulated as a noncooperative game that incorporates user association, spectrum allocation, and load balancing. To solve this problem, a distributed algorithm based on the machine learning framework of echo state networks is proposed using which the small base stations autonomously choose their optimal bands allocation strategies while having only limited information on the network's and users' states. It is shown that the proposed algorithm converges to a stationary mixed-strategy distribution which constitutes a mixed strategy Nash equilibrium for the studied game. Simulation results show that the proposed approach yields significant gains, in terms of the sum-rate of the 50th percentile of users, that reach up to 60% and 78%, respectively, compared to Q-learning and Q-learning without decoupling. The results also show that ESN significantly provides a considerable reduction of information exchange for the wireless network.

description: We use near ultraviolet and optical photometry to investigate the dust properties in the nearby starburst galaxy M82. By combining imaging from the Swift/UVOT instrument and optical data from the Sloan Digital Sky Survey, we derive the extinction curve parameterized by the standard Rv factor, and the strength of the NUV 2175 A feature - quantified by a parameter B -- out to projected galactocentric distances of 4 kpc. Our analysis is robust against possible degeneracies from the properties of the underlying stellar populations. Both B and Rv correlate with galactocentric distance, revealing a systematic trend of the dust properties. Our results confirm previous findings that dust in M82 is better fit by a Milky Way standard extinction curve (Hutton et al.), in contrast to a Calzetti law. We find a strong correlation between Rv and B, towards a stronger NUV bump in regions with higher Rv, possibly reflecting a distribution with larger dust grain sizes. The data we use were taken before SN2014J, and therefore can be used to probe the properties of the interstellar medium before the event. Our Rv values around the position of the supernova are significantly higher than recent measurements post-SN2014J (Rv~1.4). This result is consistent with a significant change in the dust properties after the supernova event, either from disruption of large grains or from the contribution by an intrinsic circumstellar component. Intrinsic variations among supernovae not accounted for could also give rise to this mismatch.

Scalable Task-Based Algorithm for Multiplication of Block-Rank-Sparse Matrices

description: A task-based formulation of Scalable Universal Matrix Multiplication Algorithm (SUMMA), a popular algorithm for matrix multiplication (MM), is applied to the multiplication of hierarchy-free, rank-structured matrices that appear in the domain of quantum chemistry (QC). The novel features of our formulation are: (1) concurrent scheduling of multiple SUMMA iterations, and (2) fine-grained task-based composition. These features make it tolerant of the load imbalance due to the irregular matrix structure and eliminate all artifactual sources of global synchronization.Scalability of iterative computation of square-root inverse of block-rank-sparse QC matrices is demonstrated; for full-rank (dense) matrices the performance of our SUMMA formulation usually exceeds that of the state-of-the-art dense MM implementations (ScaLAPACK and Cyclops Tensor Framework).

A Literature Review of Stigma and Barriers to Mental Health Care in the U. S. Military
Creators: name: Garland, Eugene
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 2017

description: After 15 years of war and global conflict the need for psychological health care in the U. S. military has risen exponentially. At military medical treatment facilities, the increased demand for psychological health care has outstripped the mental health resources available, thus creating barriers that hamper the delivery of the effective, timely, and appropriate levels of care provided (Glasmeier, Schultheis, Sassi, Chuvala, Bell, Fay, & Fradino, 2016). Despite the increase in demand for mental health services, Sharp et al. estimated 60% of service members in need of mental health care do not seek care in the military; not because of the availability of services, but primarily because of the stigma associated with mental health care. As a result, stigma is perhaps is the biggest factor that deters service members from initiating mental health care (Sharp et al., 2015). In military culture, seeking care for mental health issues is seen as weakness with perceived negative career consequences. Service members quickly develop negative beliefs regarding mental health care and as a consequence, those with psychological distress choose not to pursue mental health treatment because of the stigma and perceptions associated with seeking care. The military’s pervasive belief in “toughing out” psychological distress and not seeking care for mental health issues results in inadequate mental health treatment of service members arguably creating a serious emerging public health issue. It has been well established in the literature that stigma associated with mental health care in the military is a predominant barrier to care. Additionally, a common theme that percolates to the surface is that military leadership and organizational climate are predominant contributors to the stigma barrier associated with service members choosing not to seek mental health care. Leaders tend to judge service members who seek mental health care as broken and often express opinions that the military mission comes before wellness. A more complicated barrier in seeking mental healthcare is the potential negative career consequences on service members. Certain psychological disorders and medical treatment for those conditions can have legitimate repercussions for employment that relate to the ability to accomplish specific missions. Further, some service members perceive that seeking any type of care for general counseling, mental health, or behavioral issues will have similar negative career consequences if leadership becomes aware of their treatment. There is fear that it seeking care will reflect poorly on their performance reports and career (Miggantz, n. d.).

Uplink Downlink Rate Balancing and throughput scaling in FDD Massive MIMO Systems

description: In this work we extend the concept of uplink-downlink rate balancing to frequency division duplex (FDD) massive MIMO systems. We consider a base station with large number antennas serving many single antenna users. We first show that any unused capacity in the uplink can be traded off for higher throughput in the downlink in a system that uses either dirty paper (DP) coding or linear zero-forcing (ZF) precoding. We then also study the scaling of the system throughput with the number of antennas in cases of linear Beamforming (BF) Precoding, ZF Precoding, and DP coding. We show that the downlink throughput is proportional to the logarithm of the number of antennas. While, this logarithmic scaling is lower than the linear scaling of the rate in the uplink, it can still bring significant throughput gains. For example, we demonstrate through analysis and simulation that increasing the number of antennas from 4 to 128 will increase the throughput by more than a factor of 5. We also show that a logarithmic scaling of downlink throughput as a function of the number of receive antennas can be achieved even when the number of transmit antennas only increases logarithmically with the number of receive antennas.
