How gas-dynamic flare models powered by Petschek reconnection differ from those with ad hoc energy sources

description: Aspects of solar flare dynamics, such as chromospheric evaporation and flare light-curves, have long been studied using one-dimensional models of plasma dynamics inside a static flare loop, subjected to some energy input. While extremely successful at explaining the observed characteristics of flares, all such models so far have specified energy input ad hoc, rather than deriving it self-consistently. There is broad consensus that flares are powered by magnetic energy released through reconnection. Recent work has generalized Petschek's basic reconnection scenario, topological change followed by field line retraction and shock heating, to permit its inclusion into a one-dimensional flare loop model. Here we compare the gas dynamics driven by retraction and shocking to those from more conventional static loop models energized by ad hoc source terms. We find significant differences during the first minute, when retraction leads to larger kinetic energies and produces higher densities at the loop top, while ad hoc heating tends to rarify the loop top. The loop-top density concentration is related to the slow magnetosonic shock, characteristic of Petschek's model, but persists beyond the retraction phase occurring in the outflow jet. This offers an explanation for observed loop-top sources of X-ray and EUV emission, with advantages over that provided by ad hoc heating scenarios. The cooling phases of the two models are, however, notably similar to one another, suggesting observations at that stage will yield little information on the nature of energy input.

description: While libraries employ marketing in various forms, the challenge is keeping up with the rapidly changing discourse concerning marketing that exists outside of the library and information science (LIS) field.  This research examines an innovative approach to marketing undertaken by the North Carolina Biotechnology Center Library. The case study specifically investigates the implementation of narrative marketing and appreciative inquiry within the framework of previously established best practices for library marketing. This research demonstrates how implementing narrative marketing enables libraries to conduct evidence based librarianship, and documents the entire process used by the North Carolina Biotech Library to create a narrative marketing plan, from its initial development to its implementation. This process included an internal assessment of the library's service offerings, as well as a survey of the library's users. The data gathered enabled the library staff to justify which services to emphasize in the library's narrative campaign.

description: We study the phenomenological implications of the recent neutrino data for class B of two texture zeros and two vanishing cofactors for Majorana neutrinos in the flavor basis. We find that classes $B_{1}$($B_2$) of two texture zeros and classes $B_5$($B_6$) of two vanishing cofactors have similar predictions for neutrino oscillation parameters for the same mass hierarchy. Similar predictions for classes $B_3$($B_4$) of two texture zeros and classes $B_3$($B_4$) of two vanishing cofactors are expected. However, a preference for a shift in the quadrant of the Dirac-type CP violating phase($δ$) in contrast to the earlier analysis has been predicted for a relatively large value of the reactor neutrino mixing angle($θ_{13}$) for class B of two texture zeros and two vanishing cofactors for an inverted mass spectrum. No such shift in the quadrant of $δ$ has been found for the normal mass spectrum.

The Transformation of the UN Convention on Contracts for the International Sale of Goods (CISG) into the UK Legal Order: Two Legislative Models
Creators: name: Georgiado, Katerina
Publisher: name: University of Derby
Year: 2014

description: A number of common law countries such as Canada, New Zealand and the United States have already successfully implemented the CISG. Furthermore, leading civil law countries such as Germany and the Scandinavian countries have also implemented the UN Convention there is reason to believe that if applied by the UK, it will prove beneficial. From a political perspective, the United Kingdom reflects a negative image as being a reluctant participant in international trade law initiatives. UK law does not have a special body of rules applicable to international sales; it has a body of common rules which are not devised for international transactions. This thesis suggests that the CISG may be transformed in the UK legal order through two legislative models: 1. À la carte Model The CISG is an ‘à la carte’ Convention; provisions may be selected from the CISG in the same way we choose a meal from a restaurant’s menu. This is the à la carte model. In other words, the UK when creating the Act transforming the CISG in the UK legal order may amend the UN Convention 1980 in order to adjust it to the UK legal system. In that sense, the UK may declare at the time of ratification, according to Article 92 of the CISG, to either omit part II or III of the Convention. This model comprises of three sub-models and if implemented will be an ‘add on’ to the Sale of Goods Act 1979. 2. Parallel Model In legislative terms, the CISG could exist parallel to the Sales of Goods Act 1979, parties wishing to enter into an international transaction may conclude a contract either on CISG terms or under the Sales of Goods Act 1979. In this model a CISG Act will be required. This model will satisfy both the traders who wish to employ modern law especially designed for international contracts and those who are rather conservative and prefer to employ the old and familiar Sales of Goods Act 1979.

description: A semiconductor quantum dot can generate highly coherent and indistinguishable single photons. However, intrinsic semiconductor dephasing mechanisms can reduce the visibility of two-photon interference. For an electron in a quantum dot, a fundamental dephasing process is the hyperfine interaction with the nuclear spin bath. Here we directly probe the consequence of the fluctuating nuclear spins on the elastic and inelastic scattered photon spectra from a resident electron in a single dot. We find the nuclear spin fluctuations lead to detuned Raman scattered photons which are distinguishable from both the elastic and incoherent components of the resonance fluorescence. This significantly reduces two-photon interference visibility. However, we demonstrate successful screening of the nuclear spin noise which enables the generation of coherent single photons that exhibit high visibility two-photon interference.

description: We give improved hitting sets for two special cases of Read-once Oblivious Arithmetic Branching Programs (ROABP). First is the case of an ROABP with known order of the variables. The best previously known hitting set for this case had size $(nw)^{O(\log n)}$ where $n$ is the number of variables and $w$ is the width of the ROABP. Even for a constant-width ROABP, nothing better than a quasi-polynomial bound was known. We improve the hitting-set size for the known-order case to $n^{O(\log w)}$. In particular, this gives the first polynomial-size hitting set for constant-width ROABP (known-order). However, our hitting set only works when the characteristic of the field is zero or large enough. To construct the hitting set, we use the concept of the rank of the partial derivative matrix. Unlike previous approaches which build up from mapping variables to monomials, we map variables to polynomials directly. The second case we consider is that of polynomials computable by width-$w$ ROABPs in any order of the variables. The best previously known hitting set for this case had size $d^{O(\log w)}(nw)^{O(\log \log w)}$, where $d$ is the individual degree. We improve the hitting-set size to $(ndw)^{O(\log \log w)}$.

Phase Separation Induced by Symmetric Monocycle Optical Pulse in Extended Hubbard Models

description: Many-electron dynamics induced by a symmetric monocycle electric-field pulse of large amplitude is theoretically investigated in one- and two-dimensional half-filled extended Hubbard models on regular lattices (i.e., without dimerization) using the exact diagonalization method for small systems and the Hartree-Fock approximation for large systems. The formation of a negative-temperature state and the change from repulsive interactions to effective attractive interactions are shown to be realized for a wide region of the field amplitude and the excitation energy. For a nonnegligible intersite repulsive interaction, the numerical results are consistent with the fact that the phase separation between charge-rich and charge-poor regions is caused by the corresponding effective attraction.

description: Exploration of real-time summarization (RTS) methodologies and applications to esports events on Twitter. The goal of this study is to evaluate the effectiveness of real-time summarization techniques at esports event detection, highlight summarization, and timeline generation.  A two-step system of event-prediction and summarization is proposed. First, using Twitter as the data source, events in an esports game are predicted through machine-learning and classification to determine event occurrences. Four major classification features and five standard classification models (Naive Bayes, Logistic Regression, Decision Trees, K-Nearest Neighbors, Support Vector Machines) are evaluated to identify an optimal event-detection model. Second, natural-language text processing functions such as term-frequency and TF.IDF are evaluated for effective event summarization and to confirm successful event-detection. The CART (classification and regression tree) model is selected as the most optimal model for event-detection, predicting in-game esports events with 70% accuracy. This study demonstrates the application of Twitter as a data source in detecting real-time esports events.

description: The Alpha Magnetic Spectrometer (AMS) is a precision particle physics detector operating at an altitude of 410 km aboard the International Space Station. The AMS silicon tracker, together with the permanent magnet, measures the rigidity (momentum/charge) of cosmic rays in the range from 0.5 GV to several TV. In order to have accurate rigidity measurements, the positions of more than 2000 tracker modules have to be determined at the micron level by an alignment procedure. The tracker was first aligned using the 400 GeV/c proton test beam at CERN and then re-aligned using cosmic-ray events after being launched into space. A unique method to align the permanent magnetic spectrometer for a space experiment is presented. The developed underlying mathematical algorithm is discussed in detail.

description: This study intended to determine how the elimination of gallows variants from the transcription set change the results of statistical queries on the Voynich manuscript. It was hypothesized that the gallows variants in the Voynich manuscript alphabet are null characters, and that removing them would not have a statistically relevant impact on correlational power curves. Voynich-based text samples were created that manipulated and removed gallows variants in different ways. These were analyzed and compared to the original text, looking for similarity and divergence. The actual analysis was a straightforward application of Spearman's rank correlation coefficient to nine separate data samples, along with the source text and two natural language control files written in vulgate Latin and Arabic, respectively. The study demonstrated that the removal of gallows variants effected the statistical measures in ways inconsistent with null characters.

description: Singlet-paired coupled cluster doubles (CCD0) is a simplification of CCD that relinquishes a fraction of dynamic correlation in order to be able to describe static correlation. Combinations of CCD0 with density functionals that recover specifically the dynamic correlation missing in the former have also been developed recently. Here, we assess the accuracy of CCD0 and CCD0+DFT (and variants of these using Brueckner orbitals) as compared to well-established quantum chemical methods for describing ground-state properties of singlet actinide molecules. The $f^0$ actinyl series (UO$_2^{2+}$, NpO$_2^{2+}$, PuO$_2^{2+}$), the isoelectronic NUN, and Thorium (ThO, ThO$^{2+}$) and Nobelium (NoO, NoO$_2$) oxides are studied.

description: In recent years, the federal government has mandated that data produced using federal funds be made available to the public. This, and the recent surge in the amount of data produced and the size of datasets, have made the pressure to share data ever the more urgent. Data can be shared using open access repositories, which can be institutional or domain-specific. In the social sciences in particular, data sharing is unique because of the various sources and types of data produced. This paper examined the usage patterns of the datasets in one social science repository based on production date. It found that the average number of download statistics for each year was remarkably consistent, but the data were extremely skewed. Further analyses could look at usage patterns based on topic/keyword, non-use of datasets, or time of usage of particular datasets.

description: The understanding and interpretation of complex 3D environments is a key challenge of autonomous driving. Lidar sensors and their recorded point clouds are particularly interesting for this challenge since they provide accurate 3D information about the environment. This work presents a multimodal approach based on deep learning for panoptic segmentation of 3D point clouds. It builds upon and combines the three key aspects multi view architecture, temporal feature fusion, and deep sensor fusion.

description: The purpose of this study was to gain an understanding of how fictional female detectives have been portrayed between 1960 and the present in American series novels. Three novels were chosen to represent each of the decades between 1960 and 2006. Each of the fifteen novels was the debut novel in a series. A content analysis was performed based on a list of frequently occurring characteristics. The frequency of these characteristics was charted in order to determine trends that developed during the time period represented. Findings indicate that after the proliferation of the professional detective character in the 1980s and 1990s, the 2000s represent a return to a depiction of amateur detectives in addition to increasing autonomy in the primary occupations of these sleuths.

The ultimate tactics of self-referential systems

Subjects: subject: History and Philosophy of Physics (physics.hist-ph)
subject: FOS: Physical sciences

description: Mathematics is usually regarded as a kind of language. The essential behavior of physical phenomena can be expressed by mathematical laws, providing descriptions and predictions. In the present essay I argue that, although mathematics can be seen, in a first approach, as a language, it goes beyond this concept. I conjecture that mathematics presents two extreme features, denoted here by {\sl irreducibility} and {\sl insaturation}, representing delimiters for self-referentiality. These features are then related to physical laws by realizing that nature is a self-referential system obeying bounds similar to those respected by mathematics. Self-referential systems can only be autonomous entities by a kind of metabolism that provides and sustains such an autonomy. A rational mind, able of consciousness, is a manifestation of the self-referentiality of the Universe. Hence mathematics is here proposed to go beyond language by actually representing the most fundamental existence condition for self-referentiality. This idea is synthesized in the form of a principle, namely, that {\sl mathematics is the ultimate tactics of self-referential systems to mimic themselves}. That is, well beyond an effective language to express the physical world, mathematics uncovers a deep manifestation of the autonomous nature of the Universe, wherein the human brain is but an instance.

description: Hot subdwarf stars (sdO/Bs) are the stripped cores of red giants located at the bluest extension of the horizontal branch. They constitute the dominant population of UV-bright stars in old stellar environments and are most likely formed by binary interactions. We perform the first systematic, spectroscopic analysis of a sample of those stars in the Galactic halo based on data from SDSS. In the course of this project we discovered 177 close binary candidates. A significant fraction of the sdB binaries turned out to have close substellar companions, which shows that brown dwarfs and planets can significantly influence late stellar evolution. Close hot subdwarf binaries with massive white dwarf companions on the other hand are good candidates for the progenitors of type Ia supernovae. We discovered a hypervelocity star, which not only turned out to be the fastest unbound star known in our Galaxy, but also the surviving companion of such a supernova explosion.

Modeling solar coronal bright point oscillations with multiple nanoflare heated loops

description: Intensity oscillations of coronal bright points (BPs) have been studied for past several years. It has been known for a while that these BPs are closed magnetic loop like structures. However, initiation of such intensity oscillations is still an enigma. There have been many suggestions to explain these oscillations, but modeling of such BPs have not been explored so far. Using a multithreaded nanoflare heated loop model we study the behavior of such BPs in this work. We compute typical loop lengths of BPs using potential field line extrapolation of available data (Chandrashekhar et al. 2013), and set this as the length of our simulated loops. We produce intensity like observables through forward modeling and analyze the intensity time series using wavelet analysis, as was done by previous observers. The result reveals similar intensity oscillation periods reported in past observations. It is suggested these oscillations are actually shock wave propagations along the loop. We also show that if one considers different background subtractions, one can extract adiabatic standing modes from the intensity time series data as well, both from the observed and simulated data.

description: This paper examines the history of professional guidelines for school library media specialists. The most recent guidelines strongly advocate that the school library media specialist function as both teacher and curriculum developer. These roles necessitate that school library media specialists collaborate extensively with classroom-based teachers. The websites of sixty-three ALA (American Library Association) and NCATE (National Council for Accreditation of Teacher Education)-accredited graduate programs of library science/school library media were examined to see if collaboration was listed as a course objective within any of the required courses for certification as a school library media specialist. Course syllabi were also examined for specific methods of teaching collaboration skills. While most of the reviewed programs list collaboration as a course objective in at least one required course, the degree of emphasis placed on developing collaboration skills varies considerably within surveyed programs.

description: The potential bias on the part of librarians with a secondary subject degree is explored as it appears in the library catalog through collection development. The number of books in a given library in a specific subject area is compared to determine if any bias exists in librarians with a Ph. D. A slight bias is detected as there often is a greater percentage of books in the subject area chosen by the librarian with the Ph. D. but it is concluded that further study is needed.

description: This paper presents a dual receding horizon output feedback controller for a general non linear stochastic system with imperfect information. The novelty of this controller is that stabilization is treated, inside the optimization problem, as a negative drift constraint on the control that is taken from the theory of stability of Markov chains. The dual effect is then created by maximizing information over the stabilizing controls which makes the global algorithm easier to tune than our previous algorithm. We use a particle filter for state estimation to handle nonlinearities and multimodality. The performance of this method is demonstrated on the challenging problem of terrain aided navigation.
Rotationally Symmetric Tilings with Convex Pentagons and Hexagons

description: In contrast to many known results concerning periodic tilings of the Euclidean plane with pentagons, here tilings with rotational symmetry are investigated. A certain class of convex pentagons is introduced. It can be shown that for any given symmetry type $\mathbf{C}_{n}$ or $\mathbf{D}_{n}$ there exists a monohedral tiling generated by a pentagon from this class. For $n>1$ each of these tilings is also a spiral tiling with $n$ arms. As a byproduct it follows that the same holds for convex hexagons.

description: The notion of the holomorph of a generalized Bol loop (GBL) is characterized afresh. The holomorph of a right inverse property loop (RIPL) is shown to be a GBL if and only if the loop is a GBL and some bijections of the loop are right (middle) regular. The holomorph of a RIPL is shown to be a GBL if and only if the loop is a GBL and some elements of the loop are right (middle) nuclear. Necessary and sufficient condition for the holomorph of a RIPL to be a Bol loop are deduced. Some algebraic properties and commutative diagrams are established for a RIPL whose holomorph is a GBL.

description: It has recently been discovered that some, if not all, classical novae emit GeV gamma-rays during outburst. Despite using an unreliable method to determine its distance, previous work showed that nova V1324 Sco was the most gamma-ray luminous of all gamma-ray-detected novae. We present here a different, more robust, method to determine the reddening and distance to V1324 Sco using high-resolution optical spectroscopy. Using two independent methods we derived a reddening of E(B-V) = 1.16 +/- 0.12 and a distance rD > 6.5 kpc. This distance is >40% greater than previously estimated, meaning that V1324 Sco has an even higher gamma-ray luminosity than previously calculated. We also use periodic modulations in the brightness, interpreted as the orbital period, in conjunction with pre-outburst photometric limits to show that a main-sequence companion is strongly favored.

Free computer software

description: This paper examines whether the library community should support the development of open source software, software whose incensing allows its source code, the part of a computer program that is readable by human, to be redistributed and/or modified without restriction or charge. Included is an investigation into the present state of library-specific open source software and a discussion on the ideological and practical strengths and weaknesses of open source software in general. In addition, this paper explores the similarities between the "hacker culture" of the programming world and the traditional "gift culture" of the library community. Problems implementing open source software solutions are discussed, as are the strengths and weaknesses of library-specific open source software. In the final analysis, the support of open source software is seen as a positive step for the library community as it builds on the community's strengths while minimizing its weaknesses.

description: This study describes a questionnaire survey of and interviews with students of the UNC-CH School of Public Health Department of Maternal and Child Health. The survey and interviews were conducted to evaluate the design of an interactive study guide offered as part of a World Wide Web-based college course. The results of the study identified a discrepancy in the perceived success of the design of the study guide between students who used the guide for the college course and those who used the guide as a supplemental educational resource only. Based on the results, the investigator suggests a number of recommendations to improve the experience of all students using the study guide.

description: This paper presents state estimation and stochastic optimal control gathered in one global optimization problem generating dual effect i.e. the control can improve the future estimation. As the optimal policy is impossible to compute, a sub-optimal policy that preserves this coupling is constructed thanks to the Fisher Information Matrix (FIM) and a Particle Filter. This method has been applied to the localization and guidance of a drone over a known terrain with height measurements only. The results show that the new method improves the estimation accuracy compared to nominal trajectories.

Immigrants--Undocumented
Immigrants

description: This paper presents a study of common themes in young adult (YA) and middle grades novels published between 2006 and 2015 that feature young, undocumented immigrant protagonists who live in the United States.  The themes found in the novels include the realistic yet sometimes sanitized portrayal of the violent experiences of undocumented immigrants, the protagonists' perilous journeys to the United States, their silence over their status as undocumented immigrants, their refusal to be victims which corresponds with a demonstration of agency, their desire for and assistance in getting an education, and their development or display of a hybrid identity.  Overall, the novels have happy endings even in situations in which the protagonists do not obtain United States citizenship.  Although the prevalence of happy endings may not be entirely true-to-life, reading the novels may be a starting point for exploring issues relevant to undocumented immigration.
Prediction of the morphological evolution of a splashing drop using an encoder-decoder

description: The impact of a drop on a solid surface is an important phenomenon that has various implications and applications. However, the multiphase nature of this phenomenon causes complications in the prediction of its morphological evolution, especially when the drop splashes. While most machine-learning-based drop-impact studies have centred around physical parameters, this study used a computer-vision strategy by training an encoder-decoder to predict the drop morphologies using image data. Herein, we show that this trained encoder-decoder is able to successfully generate videos that show the morphologies of splashing and non-splashing drops. Remarkably, in each frame of these generated videos, the spreading diameter of the drop was found to be in good agreement with that of the actual videos. Moreover, there was also a high accuracy in splashing/non-splashing prediction. These findings demonstrate the ability of the trained encoder-decoder to generate videos that can accurately represent the drop morphologies. This approach provides a faster and cheaper alternative to experimental and numerical studies.
