description: Nonlinear processes with individual quanta beyond bilinear interactions are essential for quantum technology with bosonic systems. Diverse coherent splitting and merging of quanta in them already manifest in the estimation of their nonlinear coupling from observed statistics. We derive non-trivial, but optimal strategies for sensing the basic and experimentally available trilinear interactions using non-classical particle-like Fock states as a probe and feasible measurement strategies. Remarkably, the optimal probing of nonlinear coupling reaches estimation errors scaled down with $N^{-1/3}$ for overall $N$ of quanta in specific but available high-quality Fock states in all interacting modes. It can reveal unexplored aspects of nonlinear dynamics relevant to using such nonlinear processes in bosonic experiments with trapped ions and superconducting circuits and opens further developments of quantum technology with them.

description: This study aimed to address the knowledge gaps on adaptive capacity of rural farming households to slow-onset hazards such as seawater intrusion. It defined household‐level variables that can potentially explain adaptive capacity by using a principal component analysis and a regression model. In addition, it aimed to develop a measure-based index (MAI) to account for adaptation processes. The developed measure-based adaptation index addressed a number of shortcomings in previous studies and captured the variation in adaptation measures that rice farmers implement. The results indicated that adaptation takes place at different levels based on the propensity to adapt, the variety and diversity of adoption of various measures, the feasibility of the various measures, and the varying conditions of seawater intrusion. The research established a model of adaptation for seawater intrusion largely influenced by the rice farmers' economic capacity, which is crucial in optimizing the adaptation measures employed.

description: Density functional calculations within the weighted density approximation (WDA) are presented for YH$_3$ and LaH$_3$. We investigate some commonly used pair-distribution functions G. These calculations show that within a consistent density functional framework a substantial insulating gap can be obtained while at the same time retaining structural properties in accord with experimental data. Our WDA band structures agree with those of $GW$ approximation very well, but the calculated band gaps are still 1.0-2.0 eV smaller than experimental findings.

Improving efficiency and accuracy of administrative data linkage: can methods from other disciplines help?
Creators: name: Kakia Chatsiou
Publisher: name: Zenodo
Year: 2015

description: One of the great challenges of enabling access to linked de-identified administrative data is the accuracy and quick delivery of pre-processing and linkage of such large datasets. While quite a lot of work needs to be done in cleaning these datasets and getting them ready to be linked with other datasets, only some of the records are successfully linked using automated methods (by i.e. using deterministic or probabilistic methods) while most are linked by indexing professionals. Clerical data linkage while more accurate is more resource intensive and time consuming and adds to the preparation time needed for the researchers to access the data they need for their research. This paper will provide an overview of current methods for preparing and linking administrative records as used by the Administrative Data Research Network, a UK-wide partnership between universities, government departments and agencies, national statistics authorities, funders and the wider research community. We will present information on quality, accuracy and performance and discuss how methods from other disciplines such as Natural Language Processing, have been dealing with similar challenges when working with similar goals in mind, such as when trying to disambiguate named entities in large corpora/datasets.

description: Securing an understanding of public attitudes to the use and linking of administrative data has been the cornerstone to setting up the new Administrative Data Research Network. The Network is a UK-wide partnership between universities, government bodies, national statistics authorities and the wider research community www.adrn.ac.uk . Accessing and linking administrative data can bring benefits to society but people worry that data sharing is a risk to their privacy and security. Central to our work is the need to communicate with a broad church e.g. the general public, government bodies, academia, the third sector and our own Network. This is borne out of a need to be transparent, inclusive and trusted. One of our challenges to reduce the public's data trust deficit is to balance the communications messages so as not to increase fear by increasing awareness. This is an exercise in risk management, as without widespread communications targeted at all levels of society the benefits may not be realised. The Network's role is to both secure the public's trust and provide a service to researchers that is secure, lawful and ethical, run by experts in the field who ensure privacy is protected.

description: The dense-matter equation of state (EOS) under neutron-star conditions is investigated. We focus on the qualitative behavior of the speed of sound and its average. We characterize and compare the theoretical criteria for identifying nearly conformal matter. We find that the consistency of these criteria in determining the onset of conformal matter is dictated by the combined state-of-the-art theoretical and astrophysical constraints.

SowiDataNet - Bringing social and economic research data together
Creators: name: Linne, Monika
Publisher: name: Zenodo
Year: 2015

description: Flexible data distribution and the reuse of research data are becoming increasingly relevant in the social sciences. Therefore, GESIS in collaboration with the Social Science Centre Berlin, the German Institute for Economic Research, and the German National Library of Economics started the development of SowiDataNet. The overarching - and so far in Germany unique - objective is the construction of an infrastructure for decentralized research data from the social and economic sciences in Germany. At present, the holding of research data in Germany is heavily fragmented, which precludes a user-friendly, centralized and therefore quick data retrieval. Due to this major hurdle, data reuse by other scholars underlies extremely high levels of complexity and effort, or in the worst - but not very uncommon - case is simply impossible. This dissatisfying situation is aimed to be resolved by SowiDataNet, which will integrate decentralized research data together within one repository-network. The core of this network will be a web-based, independent infrastructure that allows for low-threshold self-archiving, standardized documentation and distribution of research data. SowiDataNet is community driven. It focusses on the specific needs of social and economic scientists, in order to prosper the ideal of data sharing and long-term data archiving.

description: The scale of low energy c-cbar and b-bbar cross sections on light hadrons is of great importance to searches for the quark gluon plasma using the heavy-quarkonium suppression signature. Unfortunately, little is known about these near-threshold cross sections at present, and recent theoretical estimates span many orders of magnitude. Here we use experimental data on the four observed closed-flavor heavy quarkonium hadronic decays psi' -> pi pi J/psi, Upsilon' -> pi pi Upsilon, Upsilon'' -> pi pi Upsilon and Upsilon'' -> pi pi Upsilon', combined with simple models of the transition amplitudes, to estimate the pion scattering cross sections of c-cbar and b-bbar mesons near threshold. Specifically we consider the closed-flavor reactions pi J/psi -> pi psi', pi Upsilon -> pi Upsilon', pi Upsilon -> pi Upsilon'' and pi Upsilon' -> pi Upsilon'' and their time-reversed analogues. Our results may be useful in constraining theoretical models of the strong interactions of heavy quarkonia, and can be systematically improved through future detailed studies of dipion decays, notably psi' -> pi pi J/psi and Upsilon'' -> pi pi Upsilon.

description: Introduction: This review aims to assess the available technologies, advances, and trends from technological readiness level 4 to level 8 for cancer immunologic therapeutics using the association of OX40 and CPG-ODN, usually known as cancer vaccine. Areas covered: Patent documents and clinic studies referring to the use of CpG-ODN and of OX40 association for cancer therapeutics. Patent data were obtained within the worldwide basis of the European Patent Office (EPO). The 138 patents of 36 patent families found were analyzed focusing on word distribution of technology developers and potential markets, legal status, annual evolution of first priority, technological domains, applicants and co-applicants and detailed analysis of each technology. Two clinical studies are in progress. Expert opinion: Traditional methods in post cancer diagnosis are being replaced by immunological association therapies. It is expected that the development of cancer vaccines will expand the scope of cancer-specific immunotherapy, especially if associated with alternative systems for expression and delivery with future potential. It is expected that genetic and controlled and/or specific nano delivery are improved. Furthermore, these new developments will likely address the problem of long-term treatments, reducing cancer mortality and reducing patient numbers worldwide.

Year: 2015

description: A tailored approach is ideal for teaching users to work with research data, which varies by project and discipline depending on methodology, data sources and intended outcomes. In this presentation and paper three case studies will be put forth, each with different approaches to research data: primary collection, digital data reuse and mined textual data. In each example, researchers are not only working to implement a functional methodology, but also to engage students in practices that equip them with tools and skills to advance their own research trajectory. Further, these examples are from researchers in distinctly different disciplines: an architect working on climate change in Midwest river basins, a historian reconstructing the creation of our government and a professor of social work collecting wood fuel data for villages in India. The Data and GIS Services team at Washington University has partnered with each project presented to support analyses, visualization, management, preservation and sharing of research data. Methods, challenges and opportunities will be discussed.
A nested hybridizable discontinuous Galerkin method for computing second-harmonic generation in three-dimensional metallic nanostructures

description: In this paper, we develop a nested hybridizable discontinuous Galerkin (HDG) method to numerically solve the Maxwell's equations coupled with the hydrodynamic model for the conduction-band electrons in metals. By means of a static condensation to eliminate the degrees of freedom of the approximate solution defined in the elements, the HDG method yields a linear system in terms of the degrees of freedom of the approximate trace defined on the element boundaries. Furthermore, we propose to reorder these degrees of freedom so that the linear system accommodates a second static condensation to eliminate a large portion of the degrees of freedom of the approximate trace, thereby yielding a much smaller linear system. For the particular metallic structures considered in this paper, the resulting linear system obtained by means of nested static condensations is a block tridiagonal system, which can be solved efficiently. We apply the nested HDG method to compute the second harmonic generation (SHG) on a triangular coaxial periodic nanogap structure. This nonlinear optics phenomenon features rapid field variations and extreme boundary-layer structures that span multiple length scales. Numerical results show that the ability to identify structures which exhibit resonances at $ω$ and $2ω$ is paramount to excite the second harmonic response.

description: Let $h$ be a complete metric of Gaussian curvature $K_0$ on a punctured Riemann surface of genus $g \geq 1$ (or the sphere with at least three punctures). Given a smooth negative function $K$ with $K=K_0$ in neighbourhoods of the punctures we prove that there exists a metric conformal to $h$ which attains this function as its Gaussian curvature for the punctured Riemann surface. We do so by minimizing an appropriate functional using elementary analysis.

description: We argue a smallness of gauge couplings in abelian quiver gauge theories, taking the anomaly cancellation condition into account. In theories of our interest there exist chiral fermions leading to chiral gauge anomalies, and an anomaly-free gauge coupling tends to be small, and hence can give a non-trivial condition of the weak gravity conjecture. As concrete examples, we consider $U(1)^{k}$ gauge theories with a discrete symmetry associated with cyclic permutations between the gauge groups, and identify anomaly-free $U(1)$ gauge symmetries and the corresponding gauge couplings. Owing to this discrete symmetry, we can systematically study the models and we find that the models would be examples of the weak coupling conjecture. It is conjectured that a certain class of chiral gauge theories with too many $U(1)$ symmetries may be in the swampland. We also numerically study constraints on the couplings from the scalar weak gravity conjecture in a concrete model. These constraints may have a phenomenological implication to model building of a chiral hidden sector as well as the visible sector.

description: The aryl hydrocarbon receptor is a ligand dependent transcription factor which functions as an environmental sensor. Originally discovered as the sensor for man made pollutants such as 2,3,7,8-Tetrachlorodibenzo-p-dioxin (TCDD) it has recently gained prominence as an important mediator for environmental triggers via the diet or microbiota which influences many physiological functions in different cell types and tissues across the body. Notably AHR activity contributes to prevent excessive inflammation following tissue damage in barrier organs such as skin, lung or gut which has received wide attention in the past decade. In this review we will focus on emerging common AHR functions across cell types and tissues and discuss ongoing issues that confound the understanding of AHR physiology. Furthermore, we will discuss the need for deeper molecular understanding of the functional activity of AHR in different contexts with respect to development of potential therapeutic applications.

description: Background: Adenovirus is associated with respiratory tract infections in children worldwide. However, there is insufficient data about adenovirus infections in Egyptian children and the genotypes present in this infection. Objective: The aim of the present study was to investigate the prevalence of adenovirus and its genotypes in respiratory tract infection in children by real time PCR. Methods: The study was a cross- sectional study that included 100 children complaining of respiratory tract infections signs and symptoms. Laboratory investigation for adenovirus included real time polymerase chain reaction and genotypes detection by multiplex polymerase chain reaction (PCR)). Results: Adenovirus was detected by PCR for fiber gene in 11% with genotype 3 in 6 samples (54.5%) and genotype 7 in 5 samples (45.5%) positive samples for adenovirus by Multiplex PCR. The main presenting symptoms and signs in children with adenovirus detected by PCR were cough, fever, wheezing and croups (90.9%, 81.1%, 63.6%, and 63.6% respectively). The diagnosis in children with adenovirus was pneumonia in 72.7% and bronchitis in 27.7%. There were statistically insignificant differences in demographic, clinical and hematological parameters between children with adenovirus and children negative to adenovirus by PCR. Conclusion: The clinical characteristics of respiratory infections with adenovirus vary upon the age of the patients and the immune status. Therefore, there is a requirement for extensive study of adenovirus in respiratory infections in children with different ages and immune status.

description: The renormalization group relations for the higher-order hadronic vacuum polarization function perturbative expansion coefficients are studied. The folded recurrent and unfolded explicit forms of such relations are obtained. The explicit expression for the coefficients, which incorporate the contributions of the $π^{2}$-terms in the perturbative expansion of the R-ratio of electron-positron annihilation into hadrons, is derived at an arbitrary loop level. The obtained results can be employed as an independent crosscheck of the higher-order perturbative calculations of the hadronic vacuum polarization function and in the studies of the renormalization scale setting in the relevant physical observables.

Q-Step at The University of Manchester is working across politics, sociology, criminology and linguistics degree programmes to 'make numbers normal' in the classroom. In this session I will report on progress in the first 18months, presenting what happened with our 19 summer placement students when we placed them in think-tanks, polling organisations, research consultancies, city councils, the UK Data Service and market research organisations. Each student produced a poster demonstrating their experience; we celebrated these findings in an event entitled 'Stepping Out'. Moreover they produced briefing papers, blog posts, news articles, public presentations, a book chapter and in one case an evidence-based report for MPs. Some returned to their third year and chose to undertake a dissertation involving data analysis. They exceeded our, the employers, and their own expectations, setting the blueprint for 2015, when we will double the number of students, and increase the number of organisations we will place them with. This presentation tells our students', and employers' stories. from our 2014 pilot year, demonstrating how data skills acquired in the classroom travel into the workplace.

description: As galaxies evolve over time, the orbits of their constituent stars are expected to change in size and shape, moving stars away from their birth radius. Radial gas flows are also expected. Spiral arms and bars in galaxies are predicted to help drive this radial relocation, which may be possible to trace observationally via a flattening of metallicity gradients. We use data from the Mapping Nearby Galaxies at Apache Point Observatory (MaNGA) survey, part of the fourth phase of the Sloan Digital Sky Surveys (SDSS-IV), to look for correlations of the steepness of gas-phase metallicity gradients with various galaxy morphological features (e.g. presence and pitch angle of spiral arms, presence of a large scale bar, bulge size). We select from MaNGA a sample of star forming galaxies for which gas phase metallicity trends can be measured, and use morphologies from Galaxy Zoo. We observe that at fixed galaxy mass (1) the presence of spiral structure correlates with steeper gas phase metallicity gradients; (2) spiral galaxies with larger bulges have both higher gas-phase metallicities and shallower gradients; (3) there is no observable difference with azimuthally averaged radial gradients between barred and unbarred spirals and (4) there is no observable difference in gradient between tight and loosely wound spirals, but looser wound spirals have lower average gas-phase metallicity values at fixed mass. We discuss the possible implications of these observational results.

description: A sample of 2,185 Ghanaian households from the GLSS6 was examined using a latent class model of structural heterogeneity in a linear regression framework to assess their fish consumption patterns. The results suggest that Ghanaian households fall into two consumption categories, namely “traditional” and “non-traditional” households, though there is some overlap between the two household groups. Demand for fish is price inelastic in traditional households and approximately unitary elastic in non-traditional households. In traditional households, fish is complementary to poultry but a substitute for red meat. Among non-traditional consumers, fish is complementary to poultry but a substitute for red meat and pork. While price is a major concern for traditional consumers, taste, diversity, health and nutrition are more important to non-traditional consumers. Traditional consumers are in the forest region while the non-traditional consumers are in the Savannah areas.

description: We report the first results from an X-ray polarimeter with a micropattern gas proportional counter using an amorphous silicon active matrix readout. With 100% polarized X-rays at 4.5 keV, we obtain a modulation factor of 0.33 +/- 0.03, confirming previous reports of the high polarization sensitivity of a finely segmented pixel proportional counter. The detector described here has a geometry suitable for the focal plane of an astronomical X-ray telescope. Amorphous silicon readout technology will enable additional extensions and improvements.

description: We show that a subspace $S$ of the space of real analytical functions on a manifold that satisfies certain regularity properties is contained in the set of solutions of a linear elliptic differential equation. The regularity properties are that $S$ is closed in $L^2(M)$ and that if a sequence of functions $f_n$ in $S$ converges in $L^2(M)$, then so do the partial derivatives of the functions $f_n$.

description: Symbolic execution is a powerful technique for bug finding and program testing. It is successful in finding bugs in real-world code. The core reasoning techniques use constraint solving, path exploration, and search, which are also the same techniques used in solving combinatorial problems, e.g., finite-domain constraint satisfaction problems (CSPs). We propose CSP instances as more challenging benchmarks to evaluate the effectiveness of the core techniques in symbolic execution. We transform CSP benchmarks into C programs suitable for testing the reasoning capabilities of symbolic execution tools. From a single CSP P, we transform P depending on transformation choice into different C programs. Preliminary testing with the KLEE, Tracer-X, and LLBMC tools show substantial runtime differences from transformation and solver choice. Our C benchmarks are effective in showing the limitations of existing symbolic execution tools. The motivation for this work is we believe that benchmarks of this form can spur the development and engineering of improved core reasoning in symbolic execution engines.
Hadron production in heavy ion collisions: Fragmentation and recombination from a dense parton phase

description: We discuss hadron production in heavy ion collisions at RHIC. We argue that hadrons at transverse momenta P_T < 5 GeV are formed by recombination of partons from the dense parton phase created in central collisions at RHIC. We provide a theoretical description of the recombination process for P_T > 2 GeV. Below P_T = 2 GeV our results smoothly match a purely statistical description. At high transverse momentum hadron production is well described in the language of perturbative QCD by the fragmentation of partons. We give numerical results for a variety of hadron spectra, ratios and nuclear suppression factors. We also discuss the anisotropic flow v_2 and give results based on a flow in the parton phase. Our results are consistent with the existence of a parton phase at RHIC hadronizing at a temperature of 175 MeV and a radial flow velocity of 0.55c.

FUSE Measurements of Rydberg Bands of Interstellar CO between 925 and 1150 A

description: We report the detection of 11 Rydberg bands of CO in FUSE spectra of the sight line toward HD203374A. Eight of these electronic bands are seen in the interstellar medium for the first time. Our simultaneous fit of five non-Rydberg A-X bands together with the strongest Rydberg band of CO, C-X (0-0), yields a 4-component cloud structure toward the stellar target. With this model we synthesize the other Rydberg bands in order to derive their oscillator strengths. We find that the strength of some bands was underestimated in previously published results from laboratory measurements. The implication is important for theoretical calculations of the abundance of interstellar CO, because its dissociation and self shielding depend on oscillator strengths for these bands.

Quantum creep and variable range hopping of one-dimensional interacting electrons

description: The variable range hopping results for noninteracting electrons of Mott and Shklovskii are generalized to 1D disordered charge density waves and Luttinger liquids using an instanton approach. Following a recent paper by Nattermann, Giamarchi and Le Doussal [Phys. Rev. Lett. {\bf 91}, 56603 (2003)] we calculate the quantum creep of charges at zero temperature and the linear conductivity at finite temperatures for these systems. The hopping conductivity for the short range interacting electrons acquires the same form as for noninteracting particles if the one-particle density of states is replaced by the compressibility. In the present paper we extend the calculation to dissipative systems and give a discussion of the physics after the particles materialize behind the tunneling barrier. It turns out that dissipation is crucial for tunneling to happen. Contrary to pure systems the new metastable state does not propagate through the system but is restricted to a region of the size of the tunneling region. This corresponds to the hopping of an integer number of charges over a finite distance. A global current results only if tunneling events fill the whole sample. We argue that rare events of extra low tunneling probability are not relevant for realistic systems of finite length. Finally we show that an additional Coulomb interaction only leads to small logarithmic corrections.

Training for de-identifying human subjects data for sharing: a viable library service
Creators: name: Fearon, David
name: Darragh, Jennifer
Publisher: name: Zenodo
Year: 2015

description: Since 2011, Johns Hopkins Data Management Services (DMS) has provided consulting and training on managing, sharing and preserving research data, and operates the JHU Data Archive. Last year, DMS consultant Dave Fearon collaborated with Jen Darragh, JHU's Data Services and Sociology Librarian, providing training on removing identifiers from human subjects data for sharing and archiving. Both presenters attended ICPSR's 3-day summer program on Assessing and Mitigating Disclosure Risk, drawing upon course materials and additional resources to develop a one-hour session. The training emphasizes how researchers can make disclosure assessment, de-identification and sharing through repositories a viable option through techniques applied at each stage of the research cycle, in order to better meet expanding funder expectations and improving dataset impact. JHU's IRB offices vetted the content, and expressed appreciation for training on areas of disclosure assessment that they do not support extensively. A broad audience across JHU in social science, education, medicine and public health divisions spurred some customization of content and flexible blending of introductory and advanced material. We have been expanding online resources on de-identification software and exploring in-depth consulting on de-identification projects. We will discuss the training's topics and context within library and institutional research support services.

description: To get insight into the electronic properties of PrFe4P12 skutterudite, band electronic structure calculations, Total and Projected Density of States, Crystal Orbital Overlap Population and Mulliken Population Analysis were performed. The energy bands yield a semi metallic behavior with a direct gap (at gamma) of 0.02 eV. Total and Projected Density of States provided information of the contribution from each orbital of each atom to the total Density of States. Moreover, the bonding strength between some atoms within the unit cell was obtained. Mulliken Population analysis suggests ionic behavior for this compound.
How decoherence affects the security of BB84 quantum key distribution protocol

description: We present how the mechanisms of quantum Darwinism allow for the leakage of information in the standard BB84 quantum key distribution protocol, a paradigmatic prepare and measure quantum cryptography scenario.
 We work within the decoherence theory framework and employ the model of measurements provided by quantum Darwinism. We investigate how much of the information about the results crucial for the cryptographic key to be kept secret is leaked during the quantum measurement process and subsequently how much of that information might be later obtained by an eavesdropper using a type of a so-called Van Eck side-channel wiretapping.
 We also show how the security can be affected by different ways of organizing the surrounding environment into layers, e.g. rooms or other divisions affecting the spread of quantum information in the environment and its interaction, paving a venue to potential enhancements, and insight into proper engineering of shieldings for cryptographical devices.
