description: Topological containment is an important substructure relation in graph theory. A graph G is said to topologically contain another pattern graph H if a graph isomorphic to H can be obtained from G by performing a series of deletions and contractions, where contractions are limited to edges with at least one endvertex of degree 2. It is also said that G contains a subdivision of H. Determining whether some input graph G topologically contains a particular fixed pattern graph is a widely examined problem with many applications. One of the most important is Kuratowski's well known theorem characterizing planarity, which tells us that a graph is non-planar if and only if it topologically contains at least one of the graphs K5 and K3,3. The problem of topological containment has been shown by Robertson and Seymour to be polynomial-time solvable for any fixed pattern graph H. However, practical characterizations and algorithms have only been developed for a few small pattern graphs, among these being the wheels with four and five spokes. This thesis looks at topological containment of wheels with six and seven spokes. The main results are two theorems: one that characterizes graphs with no subdivisions of W6, and one that gives a characterization (up to bounded size pieces) of graphs with no subdivisions of W7. These theorems form the basis for good characterizations and efficient algorithms for topological containment of W6 and W7. A result is also given strengthening the previous characterization of graphs with no W5-subdivisions. We find new types of separating sets such that dividing a graph G along such a separating set will not alter the existence or otherwise of a Wk-subdivision in G (where k = 6 or 7, depending on which of the main theorems forbids the separating set). Similarly, we find new local reductions such that performing such a reduction on G will not alter the existence or otherwise of a Wk-subdivision in G (where k = 6 or 7, again). These separating sets and reductions are used in the two main theorems. The length and difficulty of the proofs of these theorems increase greatly as the size of the pattern graph increases. Proving a result for the wheel with six spokes requires extensive case analysis on many small graphs, and even more analysis is needed for the wheel with seven spokes. A computer program was written to automate the generation and testing of some of the graphs that arise as cases in these proofs. The main algorithm used in this program may be useful in a more general context, for developing other characterizations relating to topological containment.

description: Protecting sensitive information is a growing concern around the globe. Securing critical data in all sectors, including the business, healthcare and military sectors, has become the first priority of sensitive information management. Failing to protect this asset results in high costs and, more importantly, can also result in lost customers and investor confidence and even threaten national security. Sensitive information systems consist of three major components: communication channel, user interface and sensitive information storage; the protection of these three components equates to the protection of sensitive information itself. Previous research in this area has been limited due to the employment of long-term shared keys and public keys. Currently, no complete security solution exists to help protect sensitive information in the three components. Issues such as dynamic sensitive information ownership, group authentication and authorization and privacy protection also create challenges for the protection of sensitive information systems. The research described in this thesis is based on dynamic key theory and group key theory to present a novel security architecture to enable sensitive information systems to overcome these challenges and meet the desired security goals for the three major components. The proposed security architecture consists of dynamic key management, user-oriented group key management, authentication and authorization management and sensitive information management, which guarantee the security of the three major components of sensitive information systems. Because of the lack of the assessment properties of information security models, a new sensitive information security model is also presented in this thesis to evaluate the effectiveness of security architecture. This model proves that the security architecture satisfies the security goals. It can also be used to assess other security architectures, and thus makes a valuable contribution to the field of sensitive information systems security. In summary, the proposed security architecture offers unique features necessary for the security of sensitive information systems. It also overcomes the limitations associated with existing security approaches and enables the complete protection of the three major components of sensitive information systems.

description: Street lit novels are reemerging in popularity. Their content is as controversial as it was in the late 1960s and early 1970s when Iceberg Slim and Donald Goines were writing their similar black experience novels. Despite their controversy, major publishers sign the authors and bookstores carry the titles. Public libraries also strive to provide popular books for their patrons. This research examines whether public libraries in the Triangle-area of North Carolina own bestselling street lit titles.

description: The surging popularity of graphic novels has brought sales of comics to a level not seen in many years, due partly to broadening distribution and audiences, but other forces could be contributing to the medium's popularity. A conservative backlash and fascination with fantasy entertainment are two possible influences. The Internet allows new fans to find information quickly, our globally connected world encourages readers to seek out the diverse viewpoints in graphic novels, and Japanese comics, or manga, attract teenagers and girls. Past information on comics publishing suggest the current popularity is part of a regular cycle. But the multitasking nature of our society and entertainment encourage information gathering over multiple channels, and our dependence on visual sources of information suggests that graphics-based literature will be more important in the future.

description: In automatic fruit inspection and classification in real time modelling and segmenting the blemish from images and image sequences is an imperative pre-curser to a number of high-level computational tasks in computer vision such as fruit segmentation, identification and classification. This thesis investigates modelling methods and contributes new algorithms in this area. The research investigates advanced computer vision algorithms for fruit inspection and classification in real time. A new system architecture using advanced computer vision algorithms is introduced. The new methods with improve parameters of the existing industrial fruit sorters has increased their inspection and classification performance and ability. In general the fruits are classified for size, shape and skin blemishes. On the computer vision side the related methods include shape, surface and texture reconstruction form multiple views. On the pattern recognition side the methods applied include variety of neural networks including radial-basis functions and support vector machines. The Support Vector Machine (SVM) is a new and a capable classification method can be seen as substitute training technique for Polynomial, Radial Basis Function and Multi-Layer Perceptions classifiers. Support vector learning machines achieved high simplification ability by minimizing a bound on the expected test error; this new method has incorporated all known attributes, parameters, colour models, features and transformation of this invariance by applying transformations to support the vectors is achieved and tested for real-time application to allow fruit classification. This research work was supported in collaboration with the Industry Partner, Colour Vision Systems (CVS) and was funded and supported by Australian Research Council's (ARC) Discovery Projects funding scheme (project LP0560847). All the fruit image data, company’s research facility was used and at our discretion to modify and calibrate and setup a test bed at the CVS company’s research centre. [Author edited abstract].

description: Noise is generally thought as detrimental for energy transport in coupled oscillator networks. However, it has been shown that for certain coherently evolving systems, the presence of noise can enhance, somehow unexpectedly, their transport efficiency; a phenomenon called environment-assisted quantum transport (ENAQT) or dephasing-assisted transport. Here, we report on the experimental observation of such effect in a network of coupled electrical oscillators. We demonstrate that by introducing stochastic fluctuations in one of the couplings of the network, a relative enhancement in the energy transport efficiency of $22.5 \pm 3.6\,\%$ can be observed.
The situated software architect

description: This thesis is an examination of the practice of software design amongst professional Australian software architects. It is based on a qualitative analysis of the data arising from transcripts of in-depth interviews with twenty-four software architects and two qualitative case studies of software-architectural design within large Australian organisations. The thesis argues that the practice of software design can only be understood in a holistic sense via a pluralist perspective, and that a constructivist philosophical approach is necessary to account for the practice of software design in a meaningful way. This argument discredits rationalism and by implication modernism as inappropriate philosophical bases for the universal observation, description and comprehension of the practice of software design. The motivation for pursuing this line of investigation is twofold. Firstly, the research seeks to explicate rich and descriptive accounts of the practice of software design in Australian business and industry contexts via an interpretivist research paradigm. Secondly, it attempts to explain the apparently a-rational behaviours of professional software architects in order to separate the practitioner from a sense of inadequacy or failure that follows from the universal imposition of rationalistic design methods and paradigms. The thesis pursues these goals by attempting to fit a situated model of design to the accounts of the participants. Structuring the research process and the rich narratives that emerge from the qualitative analysis is achieved using four philosophical perspectives—rationalism, pragmatism, criticalism and radicalism. The research delivers original findings on how practicing software architects negotiate requirements in the light of known solutions, how they are bound by perspective and paradigm, and the mechanics of their personal design processes. Through these descriptions of activity, the architect is revealed as an arranger of context and situation so as to constitute an environment in which to design tacitly. The thesis concludes that a situated perspective is necessary to understand the practice of software design.

This study was conducted to determine of behaviors of information professionals had changed since earlier studies were conducted by Joan C. Durrance and Patricia Dewdney and Catherine Sheldrick Ross. Twenty students in the School of Information and Library Science at the University of North Carolina at Chapel Hill were asked to visit a public library and document their reference interview experience, to determine if librarians had improved the percentage of helpful behaviors described in earlier studies. The results of this study were consistent with earlier studies of patron determination of reference "success."

description: There is a new generation of emoticons, called emojis, that is increasingly being used in mobile communications and social media. In the past two years, over ten billion emojis were used on Twitter. Emojis are Unicode graphic symbols, used as a shorthand to express concepts and ideas. In contrast to the small number of well-known emoticons that carry clear emotional contents, there are hundreds of emojis. But what are their emotional contents? We provide the first emoji sentiment lexicon, called the Emoji Sentiment Ranking, and draw a sentiment map of the 751 most frequently used emojis. The sentiment of the emojis is computed from the sentiment of the tweets in which they occur. We engaged 83 human annotators to label over 1.6 million tweets in 13 European languages by the sentiment polarity (negative, neutral, or positive). About 4% of the annotated tweets contain emojis. The sentiment analysis of the emojis allows us to draw several interesting conclusions. It turns out that most of the emojis are positive, especially the most popular ones. The sentiment distribution of the tweets with and without emojis is significantly different. The inter-annotator agreement on the tweets with emojis is higher. Emojis tend to occur at the end of the tweets, and their sentiment polarity increases with the distance. We observe no significant differences in the emoji rankings between the 13 languages and the Emoji Sentiment Ranking. Consequently, we propose our Emoji Sentiment Ranking as a European language-independent resource for automated sentiment analysis. Finally, the paper provides a formalization of sentiment and a novel visualization in the form of a sentiment bar.

description: Cosmological fluids are commonly assumed to be distributed in a spatially homogeneous way, while their internal properties are described by a perfect fluid. As such, they influence the Hubble-expansion through their respective densities and equation of state parameters. The subject of this paper is an investigation of the fluid-mechanical properties of a dark energy fluid, which is characterised by its sound speed and its viscosity apart from its equation of state. In particular, we compute the predicted spectra for the integrated Sachs-Wolfe effect for our generalised fluid, and compare them with the corresponding predictions for weak gravitational lensing and galaxy clustering, which had been computed in previous work. We perform statistical forecasts and show that the integrated Sachs-Wolfe signal obtained by cross correlating Euclid galaxies with Planck temperatures, when joined to galaxy clustering and weak lensing observations, yields a percent sensitivity on the dark energy sound speed and viscosity. We prove that the iSW effect provides strong degeneracy breaking for low sound speeds and large differences between the sound speed and viscosity parameters.

description: A search for double-beta decays of 136Xe to excited states of 136Ba has been performed with the first phase data set of the KamLAND-Zen experiment. The 0+1, 2+1 and 2+2 transitions of 0ν\{beta}\{beta} decay were evaluated in an exposure of 89.5kg-yr of 136Xe, while the same transitions of 2ν\{beta}\{beta} decay were evaluated in an exposure of 61.8kg-yr. No excess over background was found for all decay modes. The lower half-life limits of the 2+1 state transitions of 0ν\{beta}\{beta} and 2ν\{beta}\{beta} decay were improved to T(0ν, 0+ \rightarrow 2+) > 2.6\times10^25 yr and T(2ν, 0+ \rightarrow 2+) > 4.6\times10^23 yr (90% C.L.), respectively. We report on the first experimental lower half-life limits for the transitions to the 0+1 state of 136Xe for 0ν\{beta}\{beta} and 2ν\{beta}\{beta} decay. They are T (0ν, 0+ \rightarrow 0+) > 2.4\times10^25 yr and T(2ν, 0+ \rightarrow 0+) > 8.3\times10^23 yr (90% C.L.). The transitions to the 2+2 states are also evaluated for the first time to be T(0ν, 0+ \rightarrow 2+) > 2.6\times10^25 yr and T(2ν, 0+ \rightarrow 2+) > 9.0\times10^23 yr (90% C.L.). These results are compared to recent theoretical predictions.

description: This letter proposes the use of saddle point approximation (SPA) to evaluate the outage probability of wireless cellular networks. Unlike traditional numerical integration-based approaches, the SPA approach relies on cumulant generating functions (CGFs) and eliminates the need for explicit numerical integration. The approach is generic and can be applied to a wide variety of distributions, given that their CGFs exist. We illustrate the usefulness of SPA on channel fading distributions such as Nakagami-$m$, Nakagami-$q$ (Hoyt), and Rician distributions. Numerical results validate the accuracy of the proposed SPA approach.

description: This study sets out to contribute to the understanding of current practices in the preservation and repurposing of academic monographs at university presses. With the movement of scholarly communication to online access finding strong footholds in journals and reference publishing, the academic monograph, the mainstay of university presses, has still yet to be fully exploited. This study proposes a survey of the Association of American University Presses (AAUP) member presses to determine the state of digital monographs, including their preservation and repurposing, and to examine the number of initiatives for presenting academic monographs online, and to gauge how presses are adjusting to the challenges of these new publishing paradigms. Through the use of a literature review and the survey responses, an analysis of the current state will be discussed and recommendations will be made for new publishing models.
Rapidity regulators in the semi-inclusive deep inelastic scattering and Drell-Yan processes

description: We study the semi-inclusive limit of the deep inelastic scattering and Drell-Yan (DY) processes in soft collinear effective theory. In this regime so-called threshold logarithms must be resummed to render perturbation theory well behaved. Part of this resummation occurs via the Dokshitzer, Gribov, Lipatov, Altarelli, Parisi (DGLAP) equation, which at threshold contains a large logarithm that calls into question the convergence of the anomalous dimension. We demonstrate here that the problematic logarithm is related to rapidity divergences, and by introducing a rapidity regulator can be tamed. We show that resumming the rapidity logarithms allows us to reproduce the standard DGLAP running at threshold as long as a set of potentially large non-perturbative logarithms are absorbed into the definition of the parton distribution function (PDF). These terms could, in turn, explain the steep fall-off of the PDF in the endpoint. We then go on to show that the resummation of rapidity divergences does not change the standard threshold resummation in DY, nor do our results depend on the rapidity regulator we choose to use.

description: We consider the genesis and dynamics of interfacial instability in gas-liquid flows, using as a model the two-dimensional channel flow of a thin falling film sheared by counter-current gas. The methodology is linear stability theory (Orr-Sommerfeld analysis) together with direct numerical simulation of the two-phase flow in the case of nonlinear disturbances. We investigate the influence of three main flow parameters (density contrast between liquid and gas, film thickness, pressure drop applied to drive the gas stream) on the interfacial dynamics. Energy budget analyses based on the Orr-Sommerfeld theory reveal various coexisting unstable modes (interfacial, shear, internal) in the case of high density contrasts, which results in mode coalescence and mode competition, but only one dynamically relevant unstable internal mode for low density contrast. The same linear stability approach provides a quantitative prediction for the onset of (partial) liquid flow reversal in terms of the gas and liquid flow rates. A study of absolute and convective instability for low density contrast shows that the system is absolutely unstable for all but two narrow regions of the investigated parameter space. Direct numerical simulations of the same system (low density contrast) show that linear theory holds up remarkably well upon the onset of large-amplitude waves as well as the existence of weakly nonlinear waves. In comparison, for high density contrasts corresponding more closely to an air-water-type system, although the linear stability theory is successful at determining the most-dominant features in the interfacial wave dynamics at early-to-intermediate times, the short waves selected by the linear theory undergo secondary instability and the wave train is no longer regular but rather exhibits chaotic dynamics and eventually, wave overturning.

description: Mit der fortschreitenden Weiterentwicklung von Software und der zunehmenden Nutzung des Internets bieten sich den Schülern und Studenten heute immer mehr Möglichkeiten, sich für ihre Hausaufgaben und Hausübungen zu organisieren. Im Internet existieren jetzt schon ganze Seiten, auf denen sich zum Beispiel die Übersetzungen zu lateinischen Übungstexten aus den Lehrbüchern finden lassen. Selbst wenn die Verlage der betroffenen Bücher die Schließung dieser Seiten erreichen können, dauert es nicht lange und der Inhalt findet sich an anderer Stelle wieder. Zudem werden die Lösungen ganzer Übungsblätter digitalisiert und ins Internet gestellt bzw. per Email verschickt. Die Gefahr besteht, dass Schüler und Studenten in solchen Fällen ihre Aufgaben gar nicht mehr selber machen, sondern allerhöchstens noch abschreiben. Die im eigentlichen Sinne geforderte eigene Leistung wird damit auf ein Minimum reduziert. Auch in der Mathematik wird ein solches Verhalten umso wahrscheinlicher, je mehr Textverarbeitungsprogramme mathematische Zeichensätze zur Verfügung stellen. Allerdings existiert mit OKUSON2 schon ein Programm, das in der Lage ist, individuelle Übungsblätter zu erstellen und auch einen Großteil der Lösungen zu kontrollieren. Die Anzahl von Studenten ist jedoch relativ groß, sodass viel Zeit benötigt wird, um eine solche Menge von Aufgaben manuell zu erzeugen, bis die Übungsblätter als weitestgehend individualisiert gelten können. Meine Aufgabe war es deshalb, ein Programm zu entwickeln, das Aufgaben mit ganzzahligen Lösungen zu einem bestimmten Thema generiert. Dieses Programm sollte mit OKUSON kompatibel sein, um damit die gewünschte Individualisierung zu erreichen. Bevor man sich jedoch an das Schreiben eines solchen Programms macht, das einfach irgendwelche Aufgaben und die Lösungen dazu ausgibt, sollte man sich Gedanken machen, wie solche Aufgaben überhaupt benutzt werden kön-nen und sie benutzt werden sollen. Dazu ist natürlich die Wahl des Bereiches, aus dem die Aufgaben stammen sollen, unerlässlich. In dieser Arbeit werde ich den Bereich der ähnlichen Matrizen behandeln. An dieser Stelle kommt dann auch der zweite Teil der Aufgabenstellung ins Spiel. Die Lösungen der Aufgaben sollen ganzzahlig sein. Diese Einschränkung ist insbesondere dadurch motiviert, dass es sich mit ganzen Zahlen wesentlich leichter rechnen lässt und Angaben in den Lösungsfeldern für OKU-SON so eindeutig werden oder man vor Schwierigkeiten in der Hinsicht steht, wie man eine Wurzel in ein Textfeld eingibt, ohne dass die Eingabe gegebenenfalls komplizierter als die Lösung der zugehörigen Aufgabe wird.

description: A record of one researcher's wanderings through Walker Percy's private library in the Rare Book Collection in Wilson Library at the University of North Carolina at Chapel Hill, this study provides an account of the character and extent of Percy's collection as well as a survey of selected examples of marginalia that his books contain. Opting for an impressionistic approach that relies on selective browsing in those portions of the library that Percy seems to have read with particular attentiveness, it does not aspire to offer an exhaustive catalog of the library's contents or perform a meticulous literary analysis that establishes sure connections between the books Percy read and those he wrote. Rather, the essay attempts to describe the broad contours of Percy's collection and capture the flavor and basic characteristics of his annotations in a relatively small sample. It also discusses some of the vexing perplexities involved in working with the library of a deceased writer and the ambiguous rewards of studying marginalia, a fragmentary, incomplete genre of writing that often withholds as much as it discloses.

description: N-body simulations suggest that the substructures that survive inside dark matter haloes follow universal distributions in mass and radial number density. We demonstrate that a simple analytical model can explain these subhalo distributions as resulting from tidal stripping which increasingly reduces the mass of subhaloes with decreasing halo-centric distance. As a starting point, the spatial distribution of subhaloes of any given infall mass is shown to be largely indistinguishable from the overall mass distribution of the host halo. Using a physically motivated statistical description of the amount of mass stripped from individual subhaloes, the model fully describes the joint distribution of subhaloes in final mass, infall mass and radius. As a result, it can be used to predict several derived distributions involving combinations of these quantities including, but not limited to, the universal subhalo mass function, the subhalo spatial distribution, the gravitational lensing profile, the dark matter annihilation radiation profile and boost factor. This model clarifies a common confusion when comparing the spatial distributions of galaxies and subhaloes, the so called "anti-bias", as a simple selection effect. We provide a Python code SubGen for populating haloes with subhaloes at http://icc.dur.ac.uk/data/

description: With the emerging prominence of digital humanities scholarship, academic libraries are taking steps to reevaluate approaches to research services. This study explores the nature of digital humanities research within the academic library setting, emphasizing special collections. The role of academic libraries is in flux with respect to the larger digital research environment. Academic institutions have varying definitions of digital humanities and offer a wide range of services for patrons working in the field, often necessitating an ad hoc support model.This study describes a questionnaire survey of academic special collections libraries nation-wide, and four semi-structured interviews with librarians in two public universities in North Carolina. Surveys and interviews were conducted to determine the types of research support requested by patrons related to digital humanities, and the various ways in which academic libraries accommodate those requests.

Chat Reference and Chat Speak

description: The goals of this paper are first, to gauge the amount of chat speak (abbreviations, lack of punctuation or capitalization, etc.) and informal language used in Chat Reference interviews; second, to explore any problems or potential problems of chat speak and informal language; and third, to speculate on possible solutions to these problems. Instant Messaging is a communication form that developed its own style, including abbreviations and emoticons. Since Chat Reference is an adaptation of Instant Messaging, the chances of patrons and librarians using chat shorthand are high. This shorthand may hinder the effectiveness of Chat Reference. Transcripts from the University of Chapel Hill's Davis Library (which includes librarians from Duke and North Carolina State University), along with those published in articles, will be used to explore for problems in communication. Instances of chat speak and informal language will be counted and analyzed for evident misunderstandings or other potential problems.
Unmasking the Masked Universe: the 2M++ catalogue through Bayesian eyes
Creators: name: Lavaux, Guilhem

Publisher: name: arXiv
Year: 2015
Subjects: subject: Cosmology and Nongalactic Astrophysics (astro-ph.CO)
subject: FOS: Physical sciences

description: This work describes a full Bayesian analysis of the Nearby Universe as traced by galaxies of the 2M++ survey. The analysis is run in two sequential steps. The first step self-consistently derives the luminosity dependent galaxy biases, the power-spectrum of matter fluctuations and matter density fields within a Gaussian statistic approximation. The second step makes a detailed analysis of the three dimensional Large Scale Structures, assuming a fixed bias model and a fixed cosmology. This second step allows for the reconstruction of both the final density field and the initial conditions at z=1000 assuming a fixed bias model. From these, we derive fields that self-consistently extrapolate the observed large scale structures. We give two examples of these extrapolation and their utility for the detection of structures: the visibility of the Sloan Great Wall, and the detection and characterization of the Local Void using DIVA, a Lagrangian based technique to classify structures.

description: We exactly compute the partition function for $U(2)_k\times U(2)_{-k}$ ABJM theory on $\mathbb S^3$ deformed by mass $m$ and Fayet-Iliopoulos parameter $ζ$. For $k=1,2$, the partition function has an infinite number of Lee-Yang zeros. For general $k$, in the decompactification limit the theory exhibits a quantum (first-order) phase transition at $m=2ζ$.

Upper and Lower Bounds on Optimal Success Probability of Quantum State Discrimination with and without Inconclusive Results
Creators: name: Nakahira, Kenji
name: Usuda, Tsuyoshi Sasaki
name: Kato, Kentaro
Publisher: name: arXiv
Year: 2016
Subjects: subject: Quantum Physics (quant-ph)
subject: FOS: Physical sciences

description: We propose upper and lower bounds on the maximum success probability for discriminating given quantum states. The proposed upper bound is obtained from a suboptimal solution to the dual problem of the corresponding optimal state discrimination problem. We also give a necessary and sufficient condition for the upper bound to achieve the maximum success probability; the proposed lower bound can be obtained from this condition. It is derived that a slightly modified version of the proposed upper bound is tighter than that proposed by Qiu et al. [Phys. Rev. A 81, 042329 (2010)]. Moreover, we propose upper and lower bounds on the maximum success probability with a fixed rate of inconclusive results. The performance of the proposed bounds are evaluated through numerical experiments.

Evaluation

description: In 1998, the United States Congress amended Section 508 of the Rehabilitation Act to require federal agencies to make electronic and information technology accessible. The first accessibility guidelines from the World Wide Web Consortium's Web Accessibility Initiative, Web Content Accessibility Guidelines 1.0, were published in 1999. This study tests the usable accessibility of cultural institution web sites. Four cultural institution web sites were selected, two that were WCAG 1.0 compliant and that were not, were selected for evaluation. A combination of qualitative and quantitative analysis was conducted. Significant differences were found in the perceived usability of the guideline-compliant web sites; significance was found for one of three tasks. Overall, the guideline-compliant sites received higher usability ratings, but the task completion rates did not support a claim of greater usability.

description: This study presents the results of a survey that assessed academic reference librarians' familiarity with, attitudes toward, and use of open access sources. The electronic survey was distributed using mailing lists and completed by 460 respondents. Respondents were generally familiar with open access sources, including open access journals, institutional repositories, and self-archived materials on the web. Respondents' attitudes toward open access varied, but most agreed that open access resources are high quality and that open access would benefit authors' careers. In helping researchers find open access information, more respondents had used open access journals than institutional repositories or self-archived materials. Compared to the number of respondents who had provided information to researchers about using open access resources, fewer had provided authors with information about publishing in open access resources.

Liquid jet rebound upon impact on a soft gel

description: A liquid jet can stably bounce off a sufficiently soft gel, by following the contour of the dimple created upon impact. This new phenomenon is insensitive to the wetting properties of the gels and was observed for different liquids over a wide range of surface tensions, $γ$ = 24--72 mN/m. In contrast, other jet rebound phenomena are typically sensitive to $γ$: jet rebounds off a hard solid (e.g. superhydrophobic surface) or another liquid are possible only for high and low $γ$ liquids, respectively. This is because an air layer must be stabilized between the two interfaces. For a soft gel, no air layer is necessary and jet rebound remains stable even when there is direct liquid-gel contact.
