description: Considering the large deviations of activity and current in the Asymmetric Simple Exclusion Process (ASEP), we show that there exists a non-trivial correspondence between the joint scaled cumulant generating functions of activity and current of two ASEPs with different parameters. This mapping is obtained by applying a similarity transform on the deformed Markov matrix of the source model in order to obtain the deformed Markov matrix of the target model. We first derive this correspondence for periodic boundary conditions, and show in the diffusive scaling limit (corresponding to the Weakly Asymmetric Simple Exclusion Processes, or WASEP) how the mapping is expressed in the language of Macroscopic Fluctuation Theory (MFT). As an interesting specific case, we map the large deviations of current in the ASEP to the large deviations of activity in the SSEP, thereby uncovering a regime of Kardar-Parisi-Zhang in the distribution of activity in the SSEP. At large activity, particle configurations exhibit hyperuniformity [Jack et al., PRL 114 060601 (2015)]. Using results from quantum spin chain theory, we characterize the hyperuniform regime by evaluating the small wavenumber asymptotic behavior of the structure factor at half-filling. Conversely, we formulate from the MFT results a conjecture for a correlation function in spin chains at any fixed total magnetization (in the thermodynamic limit). In addition, we generalize the mapping to the case of two open ASEPs with boundary reservoirs, and we apply it in the WASEP limit in the MFT formalism. This mapping also allows us to find a symmetry-breaking dynamical phase transition (DPT) in the WASEP conditioned by activity, from the prior knowledge of a DPT in the WASEP conditioned by the current.

description: The district heating (DH) system of Greece, mainly supported from lignite fired stations, is facing lately significant challenges. Stricter emission limits, decreased efficiency due to old age and increased costs are major challenges of the lignite sector and are expected to result in the decommissioning of several lignite-fired units in the coming years. As a result, managers of DH networks are currently investigating alternative scenarios for the substitution of thermal power that it is expected to be lost, through the integration of Renewable Energy Sources (RES) into the system. In this paper, the DH systems of Kozani and Ptolemaida are examined regarding possible introduction of RES. The first study examines district heating of Kozani and alternative future options for covering a part of city’s thermal load whereas the second study refers to a biomass CHP plant (ORC technology, 1MWe, 5MWth) to be powered from a biomass mixture (wood chips and straw).

description: A new model for viscoelastic phase separation is proposed, based on a systematically derived conservative two-fluid model. Dissipative effects are included by phenomenological viscoelastic terms. By construction, the model is consistent with the second law of thermodynamics, and we study well-posedness of the model, i.e., existence of weak solutions, a weak-strong uniqueness principle, and stability with respect to perturbations, which are proven by means of relative energy estimates. A good qualitative agreement with mesoscopic simulations is observed in numerical tests.

Paving the Way for Heat. Local Government Policies for Developing Bioenergy
Creators: name: Rygg, Bente Johnsen

Year: 2015

description: Local governments play dual roles in developing renewable energy projects. They are the targets of many goals concerning energy and climate, set by national and international actors, and they are important actors in energy planning, regulation setting, and the development of infrastructure and residential areas. In this paper, I study how local governments’ technology policies affect the actual outcome of project development based on experiences from 14 local governments. Technology policies are studied from the perspective of Sørensen’s [1] four areas of concern: direct support of innovation, infrastructure, regulation (protection and standards) and public engagement. I find that local governments use policy instruments within all four areas, and that the way local governments involves in the process of bioenergy development are surprisingly similar despite differences in location and size of both the local government and the project.

description: Background: Mean-field methods based on an energy density functional (EDF) are powerful tools used to describe many properties of nuclei in the entirety of the nuclear chart. The accuracy required on energies for nuclear physics and astrophysics applications is of the order of 500 keV and much effort is undertaken to build EDFs that meet this requirement. Purpose: The mean-field calculations have to be accurate enough in order to preserve the accuracy of the EDF. We study this numerical accuracy in detail for a specific numerical choice of representation for the mean-field equations that can accommodate any kind of symmetry breaking. Method: The method that we use is a particular implementation of 3-dimensional mesh calculations. Its numerical accuracy is governed by three main factors: the size of the box in which the nucleus is confined, the way numerical derivatives are calculated and the distance between the points on the mesh. Results: We have examined the dependence of the results on these three factors for spherical doubly-magic nuclei, neutron-rich $^{34}$Ne, the fission barrier of $^{240}$Pu and isotopic chains around Z = 50. Conclusions: Mesh calculations offer the user extensive control over the numerical accuracy of the solution scheme. By making appropriate choices for the numerical scheme the achievable accuracy is well below the model uncertainties of mean-field methods.

description: We study the long-term evolution of ejecta formed in a binary neutron star (BNS) merger that results in a long-lived remnant NS by performing a hydrodynamics simulation with the outflow data of a numerical relativity simulation as the initial condition. At the homologously expanding phase, the total ejecta mass reaches $\approx0.1\,M_\odot$ with an average velocity of $\approx0.1\,c$ and lanthanide fraction of $\approx 0.005$. We further perform the radiative transfer simulation employing the obtained ejecta profile. We find that, contrary to a naive expectation from the large ejecta mass and low lanthanide fraction, the optical emission is not as bright as that in GW170817/AT2017gfo, while the infrared emission can be brighter. This light curve property is attributed to preferential diffusion of photons toward the equatorial direction due to the prolate ejecta morphology, large opacity contribution of Zr, Y, and lanthanides, and low specific heating rate of the ejecta. Our results suggest that these light curve features could be used as an indicator for the presence of a long-lived remnant NS. We also found that the bright optical emission broadly consistent with GW170817/AT2017gfo is realized for the case that the high-velocity ejecta components in the polar region are suppressed. These results suggest that the remnant in GW170817/AT2017gfo is unlikely to be a long-lived NS, but might have collapsed to a black hole within ${\cal O}(0.1)$ s.

Designing electricity generation portfolios using the mean-variance approach
Creators: name: Cunha, Jorge
name: Ferreira, Paula Varandas
Publisher: name: International Journal of Sustainable Energy Planning and Management
Year: 2015

description: The use of the mean-variance approach (MVA) is well demonstrated in the financial literature for the optimal design of financial assets portfolios. The electricity sector portfolios are also guided by similar objectives, namely maximizing return and minimizing risk. As such, this paper proposes two possible MVA for the design of optimal renewable electricity production portfolios. The first approach is directed to portfolio output maximization and the second one is directed to portfolio cost optimization. The models implementation was achieved from data obtained for each quarter of an hour for a time period close to four years for the Portuguese electricity system. A set of renewable energy sources (RES) portfolios was obtained, mixing three RES technologies, namely hydro power, wind power and photovoltaic. This allowed to recognize the seasonality of the resources demonstrating that hydro power output is positively correlated with wind and that photovoltaic is negatively correlated with both hydro and wind. The results showed that for both models the less risky solutions are characterised by a mix of RES technologies, taking advantage of the diversification benefits. As for the highest return solutions, as expected those were the ones with higher risk but the portfolio composition largely depends on the assumed costs of each technology.

description: In the field of visual ego-motion estimation for Micro Air Vehicles (MAVs), fast maneuvers stay challenging mainly because of the big visual disparity and motion blur. In the pursuit of higher robustness, we study convolutional neural networks (CNNs) that predict the relative pose between subsequent images from a fast-moving monocular camera facing a planar scene. Aided by the Inertial Measurement Unit (IMU), we mainly focus on translational motion. The networks we study have similar small model sizes (around 1.35MB) and high inference speeds (around 10 milliseconds on a mobile GPU). Images for training and testing have realistic motion blur. Departing from a network framework that iteratively warps the first image to match the second with cascaded network blocks, we study different network architectures and training strategies. Simulated datasets and a self-collected MAV flight dataset are used for evaluation. The proposed setup shows better accuracy over existing networks and traditional feature-point-based methods during fast maneuvers. Moreover, self-supervised learning outperforms supervised learning.

description: Sulfide mineral oxidation in mine waste materials is one of the principal contributors to poor quality drainage. The oxidation process is generally limited by the diffusion of O₂ into the pore space of waste piles and rock fragments. In this study, a non-destructive method that couples laboratory measurements and modelling techniques is developed to measure the diffusive properties of common sulfide-mineral-bearing waste rock fragments. X-ray imaging is used to acquire time-series images of iodide tracer diffusion through the oxidized rim and into the unaltered core of the rock fragments. The distribution of diffusion coefficients is determined by fitting results from two-dimensional numerical diffusion simulations to the measured spatial distribution of iodide tracer. In addition, one dimensional experiments were conducted to determine pore diffusion coefficients normal and parallel to waste rock foliation/bedding planes in the oxidized and unaltered domains. The average pore-diffusion coefficient (Dₚ) values measured parallel to foliation in the unaltered core and normal to foliation in the oxidized rim of quartz-sericite schist are 3.30 × 10⁻¹⁰ ± 5.00 × 10⁻¹¹ m²/s and 8.27 × 10⁻¹¹ ± 1.46 × 10⁻¹¹ m²/s, respectively; 2.29 × 10⁻¹⁰ ± 3.07 × 10⁻¹¹ m²/s and 1.89 × 10⁻¹⁰ ± 8.82 × 10⁻¹¹ m²/s parallel to foliation in the unaltered core and oxidized rim of quartz-biotite schist, respectively; 2.34 × 10⁻¹¹ ± 3.70 × 10⁻¹² m²/s and 4.79 × 10⁻¹¹ ± 1.89 × 10⁻¹¹ m²/s in the unaltered core and oxidized rim of felsic meta-volcanic rock, respectively; and 6.75 × 10⁻¹¹ ± 5.00 × 10⁻¹² m²/s and 3.82 × 10⁻¹¹ ± 3.72 × 10⁻¹² m²/s parallel to foliation in the unaltered core and normal to foliation in the oxidized rim of quartz-muscovite schist, respectively. The Dₚ values for solutes such as O₂ and SO₄ are calculated using the known relationship between free-water diffusion coefficients for iodide and the solutes of interest. Coupled with inter-particle diffusion coefficient estimates, these data will aid in the development of numerical models that estimate oxidation rates and duration of hazardous leachate drainage from mine waste materials.

description: The interstellar magnetic field (ISMF) near the heliosphere is a basic part of the solar neighborhood that can only be studied using polarized starlight. Results of an ongoing survey of polarized starlight are analyzed with the goal of linking the interstellar magnetic field that shapes the heliosphere to the nearby field in interstellar space. New results for the direction of the nearby ISMF, based on a merit function that utilizes polarization position angles, identify several magnetic components. The dominant interstellar field, B_pol, is aligned with the direction L,B= 36.2,49.0 (+/-16.0) degrees and is within 8 degrees of the IBEX Ribbon ISMF direction. Stars tracing B_pol have the same mean distance as stars that do not trace B_pol, but show weaker polarizations consistent with lower column densities of polarizing grains. The variations in the polarization position angle directions indicate a low level of magnetic turbulence. B_pol is found after excluding polarizations that trace a separate magnetic structure that apparently is due to interstellar dust deflected around the heliosphere. Local interstellar cloud velocities relative to the LSR increase with the angles between the LSR velocities and ISMF, indicating that the kinematics of local interstellar material is ordered by the ISMF. Polarization and color excess data are consistent with an extension of Loop I to the solar vicinity. Polarizations are consistent with previous findings of more efficient grain alignment in low column density sightlines. Optical polarization and color excess data indicate the presence of nearby interstellar dust in the BICEP2 field. Color excess E(B-V) indicates an optical extinction of A_V about 0.59 mag in the BICEP2 field, while the polarization data indicate that A_V is larger than 0.09 mag. The IBEX Ribbon ISMF extends to the boundaries of the BICEP2 region.

description: In certain unconventional superconductors with sizable electronic correlations, the availability of closely competing pairing channels leads to characteristic soft collective fluctuations of the order parameters, which leave fingerprints in many observables and allow to scrutinize the phase competition. Superconducting layered materials, where electron-electron interactions are enhanced with decreasing thickness, are promising candidates to display these correlation effects. In this work, we report the existence of a soft collective mode in single-layer NbSe$_2$, observed as a characteristic resonance excitation in high resolution tunneling spectra. This resonance is observed along with higher harmonics, its frequency $Ω/2Δ$ is anticorrelated with the local superconducting gap $Δ$, and its amplitude gradually vanishes by increasing the temperature and upon applying a magnetic field up to the critical values (T$_C$ and H$_{C2}$), which sets an unambiguous link to the superconducting state. Aided by a microscopic model that captures the main experimental observations, we interpret this resonance as a collective Leggett mode that represents the fluctuation towards a proximate f-wave triplet state, due to subleading attraction in the triplet channel. Our findings demonstrate the fundamental role of correlations in superconducting 2D transition metal dichalcogenides, opening a path towards unconventional superconductivity in simple, scalable and transferable 2D superconductors.

description: We consider the van der Waals interaction between a pair of polymers with quenched heterogeneous sequences of local polarizabilities along their backbones, and study the effective pairwise interaction energy for both stiff polymers and flexible Gaussian coils. In particular, we focus on the cases where the pair of polarizability sequences are (i)~distinct and (ii)~identical. We find that the pairwise interaction energies of distinct and identical Gaussian coils are both isotropic and exhibit the same decay behavior for separations larger than the gyration radius, in contradistinction to the orientationally anisotropic interaction energies of distinct and identical stiff polymers. For both Gaussian coils and stiff polymers, the attractive interaction between identical polymers is enhanced if the polarizability sequence is more heterogeneous.

Caring for the Caring: Organizational Policies to Support Providers Working with Trauma Survivors
Creators: name: Holden, William David
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 2017

description: Caregivers working with trauma survivors frequently struggle with compassion fatigue. Employers, supervisors, and others often encourage compassion-fatigued caregivers to cultivate resilience through the practice of self-care, but organizations may structure or influence the work of caregivers in ways that reduce or intensify compassion fatigue. In this paper “compassion fatigue” refers to the range of negative responses that caregivers may have when working with trauma survivors, comprising both the emotional exhaustion of burnout and the personality changes of vicarious traumatization. In contrast “resilience” refers here to the range of positive responses that caregivers may have when working with trauma survivors, comprising a return to previous levels of positive functioning, adapting to stressful work, post-traumatic growth, and perhaps personality transformation. This paper reviews the literature describing factors contributing to compassion fatigue and recommends particular policies based on current research to reduce compassion fatigue. Ideal policies should attend closely to caregivers’ emotional responses to their clients and work environment. Examples of such policies include the expectation of ongoing clinical supervision, customary practice of evidence-based self-care techniques during the course of the working day, and generous provision of mental health services for caregivers. Organizations committed to providing mental health services should enact all of these recommended policies as far as possible; other caregiving organizations that provide services to trauma survivors, such as public health and general healthcare, should enact as many of these policies as are relevant and possible for their settings.
Molecular Diagnosis of Mycobacterium bovis Infection

description: Tuberculosis due to Mycobacterium bovis infection presents a significant public and animal health burden, in particular in economically less developed countries. Distinguishing M. bovis from other mycobacteria, and distinguishing among M. bovis strains, are important for M. bovis control and eradication, and for optimizing treatment plans for patients. Conventional diagnostic methods, such as tuberculin skin tests and microscopic examination of blood smears, are rapid and inexpensive, but generally do not allow differentiation among mycobacteria or mycobacterial strains. A variety of methods have been developed that allow detailed genetic characterization of mycobacteria. These methods are useful for epidemiologic investigation of outbreaks, identifying potential means and patterns of transmission, identifying relationships among infections in various human and animal populations, and investigating the role of wildlife reservoirs in maintenance and spread of infection. These methods can also be used to identify risk factors for transmission, to assess the effectiveness of tuberculosis control and eradication programs, and to assess quality control in laboratory testing. Limitations of these methods include higher costs, and requirements for more specialized equipment, reagents, and expertise than are needed for conventional diagnostic methods. Identifying the most appropriate method or combination of methods to use can be difficult. Factors to consider in selecting a molecular diagnostic approach include the purpose of the investigation, and the structure and molecular characteristics of the M. bovis population under investigation. Use of inappropriate methods can yield misleading results and lead to significant waste of resources.

description: In this paper, the authors establish the two-weight boundedness of the local fractional maximal operators and local fractional integrals on Gaussian measure spaces associated with the local weights. More precisely, the authors first obtain the two-weight weak-type estimate for the local-$a$ fractional maximal operators of order $α$ from $L^{p}(v)$ to $L^{q,\infty}(u)$ with $1\leq p\leq q<\infty$ under a condition of $(u,v)\in \bigcup_{b'>a} A_{p,q,α}^{b'}$, and then obtain the two-weight weak-type estimate for the local fractional integrals. In addition, the authors obtain the two-weight strong-type boundedness of the local fractional maximal operators under a condition of $(u,v)\in\mathscr{M}_{p,q,α}^{6a+9\sqrt{d}a^2}$ and the two-weight strong-type boundedness of the local fractional integrals. These estimates are established by the radialization method and dyadic approach.

Association between Time of First Publication and Future Publication Success in Research-Intensive Medical Academicians: A CrossSectional Study
Creators: name: Riggs, Kevin R.
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 2009

description: Background/Aims: Publication during medical school and residency has been associated with higher rates of publication and more citations of one's published research. However, it is unclear whether that association is seen and persists late into the careers of research intensive academicians. The purpose of this paper is to investigate this latter supposition. Methods: The authors examined the CVs of corresponding authors of articles from NEJM and JAMA from 2008. Publication records of the authors were extracted from their CVs, and citation records for each author were obtained from the Web of Science. Analysis of covariance regression models were used to examine the association between first publication during medical school, within 5 years of medical school, or beyond 5 years of medical school graduation, and future publication and citation success. Results: On adjusted analysis, those researchers who had their first publication before medical school graduation had a greater number of mean publications after medical school and during 2006-2007 (163.6 and 28.4) than those who had their first publication during the first 5 years after medical school graduation (110.7 and 18.8) or more than 5 years after graduation (59.0 and 13.1 ). Similarly, those who had their first publication before medical school graduation had a greater number of mean citations to their published work since graduation and on publications from 2006-2007 (4634 and 333) than those who had their first publication during the first 5 years after medical school graduation (2936 and 183) or more than 5 years after graduation (1512 and 143). Conclusions: Early publishing is associated with higher rates of publications and more citations of published research, and this association is maintained well into a researcher's career.

description: We study a class of gravitational lensing systems consisting of an inclined ring/belt, with and without an added point mass at the centre. We show that a common feature of such systems are so-called "pseudo-caustics", across which the magnification of a point source changes discontinuously and yet remains finite. Such a magnification change can be associated with either a change in image multiplicity or a sudden change in the size of a lensed image. The existence of pseudo-caustics and the complex interplay between them and the formal caustics (which correspond to points of infinite magnification) can lead to interesting consequences, such as truncated or open caustics and a non-conservation of total image parity. The origin of the pseudo-caustics is found to be the non-differentiability of the solutions to the lens equation across the ring/belt boundaries, with the pseudo-caustics corresponding to ring/belt boundaries mapped into the source plane. We provide a few illustrative examples to understand the pseudo-caustic features, and in a separate paper consider a specific astronomical application of our results to study microlensing by extrasolar asteroid belts.

description: Defects in solid state materials provide an ideal, robust platform for quantum sensing. To deliver maximum sensitivity, a large ensemble of non-interacting defects hosting coherent quantum states are required. Control of such an ensemble is challenging due to the spatial variation in both the defect energy levels and in any control field across a macroscopic sample. In this work we experimentally demonstrate that we can overcome these challenges using Floquet theory and optimal control optimization methods to efficiently and coherently control a large defect ensemble, suitable for sensing. We apply our methods experimentally to a spin ensemble of up to 4 $\times$ 10$^9$ nitrogen vacancy (NV) centers in diamond. By considering the physics of the system and explicitly including the hyperfine interaction in the optimization, we design shaped microwave control pulses that can outperform conventional ($π$-) pulses when applied to sensing of temperature or magnetic field, with a potential sensitivity improvement between 11 and 78\%. Through dynamical modelling of the behaviour of the ensemble, we shed light on the physical behaviour of the ensemble system and propose new routes for further improvement.

description: Magnetic properties of rocks show a wide range of geoscience applications and they are rapid and non-destructive to measure. Magnetic susceptibility is one of the most common magnetic parameters that allows to distinguish between different rock types and to understand geological processes that are related to Fe-mineralogy. The physical basis for the discrimination is the nature of magnetic minerals, their distribution, and grain size. Thus, magnetic methods show great potential for reservoir rock characterization, fabric determination, ore deposits, environmental issues, and even pore fabric studies. We particularly encourage contributions dealing with reservoir characterization applying magnetic methods from all areas of geology including method developments and applications of magnetic methods in all kinds of geological reservoir characterization.
Genetically Modified Salmon Controversies in the United States: Does the Current Regulatory Paradigm Address all the Issues?

description: If approved by the Food and Drug Administration (FDA), the genetically modified salmon will be the first genetically engineered animal available for human consumption in the United States. The country relies on the Food and Drug Administration and other federal and state agencies to develop policies that consider unbiased evidence and expert policy development in the evaluation of food products. I propose that the current information available regarding the acceptance of genetically modified salmon as a human food is not yet adequate for approval, as evidenced by the number of related public health issues that still remain unresolved. A thorough review of the literature with a focus on the United States was conducted and various perspectives were analyzed. Sources included books, websites, journal publications, news sources, government documents and publications, legal perspectives and information from biotechnology (biotech) companies. Findings revealed that genetically modified food remains a controversial topic for public health, and includes environmental, health, and ethical issues. There is still much debate about the regulation and safety of these foods in general, and escalating concern with the possibility of the genetically engineered salmon being approved for entry into the food chain without data on the long term impacts on human health and the animal population. Improved processes regarding the regulatory and safety review of genetically modified foods are necessary to safeguard the public and environment. The FDA is mandated to protect public safety, and FDA policies must put the safety of the public before the wishes of biotech companies, until the assurance of long term safety can be GM Salmon Controversies in the US 3 improved. Therefore, improved regulation, including labeling of foods with genetically modified content, can protect consumers while allowing them to make informed personal choices.

description: Device-to-device (D2D) communication has seen as a major technology to overcome the imminent wireless capacity crunch and to enable new application services. In this paper, we propose a social-aware approach for optimizing D2D communication by exploiting two layers: the social network and the physical wireless layers. First we formulate the physical layer D2D network according to users' encounter histories. Subsequently, we propose an approach, based on the so-called Indian Buffet Process, so as to model the distribution of contents in users' online social networks. Given the social relations collected by the Evolved Node B (eNB), we jointly optimize the traffic offloading process in D2D communication. In addition, we give the Chernoff bound and approximated cumulative distribution function (CDF) of the offloaded traffic. In the simulation, we proved the effectiveness of the bound and CDF. The numerical results based on real traces show that the proposed approach offload the traffic of eNB's successfully.

description: We propose that extrasolar asteroid belts can be detected through their gravitational microlensing signatures. Asteroid belt + star lens systems create so-called "pseudo-caustics", regions in the source plane where the magnification exhibits a finite but discontinuous jump. These features allow such systems to generate distinctive signatures in the microlensing light curves for a wide range of belt configurations, with source trajectories as far as tenths of the Einstein ring radius from the centre of the lens. Sample light curves for a range of asteroid belt parameters are presented. In the near future, space-based microlensing surveys like WFIRST, which will have the power to detect percent-level changes in microlensing light curves even with sub-minute exposure times, may be able to discover extrasolar asteroid belts with masses of the order of an earth mass.

description: With the urgent need to quickly reduce CO2 emissions, deep geothermal energy can provide an indispensable contribution in the future energy mix. To encourage future projects, it is essential to significantly decrease the exploration risks of geothermal projects. This reduction should encourage investments, increase the probability of success and decrease surface impact to communities. Ranging from direct exploration risks to surface implications for communities, this session is directed to uncertainty quantification and risk reduction e.g. geological modelling, novel exploration as well as reservoir testing and monitoring techniques. Armed with this knowledge, better decisions can be made for project developments, like selection of drilling targets, reservoir operations or mitigations efforts. We invite contributions on geological, geophysical and reservoir engineering aspects of uncertainty quantification and risk reduction within Geothermal energy.
