Statistical Physics of the Spatial Prisoner's Dilemma with Memory-Aware Agents

description: We introduce an analytical model to study the evolution towards equilibrium in spatial games, with `memory-aware' agents, i.e., agents that accumulate their payoff over time. In particular, we focus our attention on the spatial Prisoner's Dilemma, as it constitutes an emblematic example of a game whose Nash equilibrium is defection. Previous investigations showed that, under opportune conditions, it is possible to reach, in the evolutionary Prisoner's Dilemma, an equilibrium of cooperation. Notably, it seems that mechanisms like motion may lead a population to become cooperative. In the proposed model, we map agents to particles of a gas so that, on varying the system temperature, they randomly move. In doing so, we are able to identify a relation between the temperature and the final equilibrium of the population, explaining how it is possible to break the classical Nash equilibrium in the spatial Prisoner's Dilemma when considering agents able to increase their payoff over time. Moreover, we introduce a formalism to study order-disorder phase transitions in these dynamics. As result, we highlight that the proposed model allows to explain analytically how a population, whose interactions are based on the Prisoner's Dilemma, can reach an equilibrium far from the expected one; opening also the way to define a direct link between evolutionary game theory and statistical physics.

description: This study discusses the results of a heuristic evaluation of 80 public library websites in the state of North Carolina. Each public library website (PLW) was evaluated using a usability heuristic questionnaire, with questions covering criteria taken from human-computer interaction literature. Development of this questionnaire allowed a broad evaluation of 80 North Carolina PLWs to be conducted. The purpose of the study is to understand the extent to which PLWs in North Carolina meet basic usability heuristics. Developing a method of evaluation that can cover many PLWs of a specific locale allows librarians to use shared governance in future opportunities for investigation and improvement of websites in North Carolina public libraries. Results show that North Carolina PLWs meet some usability heuristics but not others, and that most North Carolina PLWs are more usable than they are unusable.
Odd zeta motive and linear forms in odd zeta values

description: We study a family of mixed Tate motives over $\mathbb{Z}$ whose periods are linear forms in the zeta values $ζ(n)$. They naturally include the Beukers-Rhin-Viola integrals for $ζ(2)$ and the Ball-Rivoal linear forms in odd zeta values. We give a general integral formula for the coefficients of the linear forms and a geometric interpretation of the vanishing of the coefficients of a given parity. The main underlying result is a geometric construction of a minimal ind-object in the category of mixed Tate motives over $\mathbb{Z}$ which contains all the non-trivial extensions between simple objects. In a joint appendix with Don Zagier, we prove the compatibility between the structure of the motives considered here and the representations of their periods as sums of series.

description: This paper will argue that American legal education and research is defined by three  paradigms, using the definition of a paradigm as "a set of concepts, patterns, or  assumptions to which those in a particular professional community are committed and  which forms the basis of further research."  The first paradigm is defined by the casebook, or Socratic teaching method created by  Harvard Law Dean Christopher Langdell, The second paradigm is defined by the West  digest system, created by John D. West in the late nineteenth century, and the third by  computer assisted legal research, or CALR, which has supplanted the West Digest system  as the main form of legal research in the last twenty years. The paper will further argue  that while the West Digest system influenced the development of the American legal  system in the twentieth century, so too will CALR influence the development of the law  library.

description: This case study compares the mission, role, and services of two academic libraries in an increasing digital environment as typified by the Bodleian Library and the University of North Carolina at Chapel Hill Library. The investigation shows how these factors define two different bases of knowledge: The Center of Knowledge where digital access supports the scholarly mission but is not mandatory and The Center of Information where digital access is a core part of the scholarly mission. This study began with the May, 2003 seminar at the Bodleian Library of Oxford University, Oxford, England, sponsored by the School of Information and Library Science at the University of North Carolina at Chapel Hill. A survey was also used to ascertain the similarities and differences between the Bodleian Library and the UNC Library. Ten employees from each library participated in the survey and were employed in the areas of Senior Administration, Head of a Collection, Archivist or Preservation, Information Technology, Digital Access Development, Website Design, and Fundamental Development Director at the time of this study.

description: In-Context Learning (ICL), which formulates target tasks as prompt completion conditioned on in-context demonstrations, has become the prevailing utilization of LLMs. In this paper, we first disclose an actual predicament for this typical usage that it can not scale up with training data due to context length restriction. Besides, existing works have shown that ICL also suffers from various biases and requires delicate calibration treatment. To address both challenges, we advocate a simple and effective solution, $k$NN Prompting, which first queries LLM with training data for distributed representations, then predicts test instances by simply referring to nearest neighbors. We conduct comprehensive experiments to demonstrate its two-fold superiority: 1) Calibration-Free: $k$NN Prompting does not directly align LLM output distribution with task-specific label space, instead leverages such distribution to align test and training instances. It significantly outperforms state-of-the-art calibration-based methods under comparable few-shot scenario. 2) Beyond-Context: $k$NN Prompting can further scale up effectively with as many training data as are available, continually bringing substantial improvements. The scaling trend holds across 10 orders of magnitude ranging from 2 shots to 1024 shots as well as different LLMs scales ranging from 0.8B to 30B. It successfully bridges data scaling into model scaling, and brings new potentials for the gradient-free paradigm of LLM deployment. Code is publicly available.

Generalizing Permissive-Upgrade in Dynamic Information Flow Analysis

description: Preventing implicit information flows by dynamic program analysis requires coarse approximations that result in false positives, because a dynamic monitor sees only the executed trace of the program. One widely deployed method is the no-sensitive-upgrade check, which terminates a program whenever a variable's taint is upgraded (made more sensitive) due to a control dependence on tainted data. Although sound, this method is restrictive, e.g., it terminates the program even if the upgraded variable is never used subsequently. To counter this, Austin and Flanagan introduced the permissive-upgrade check, which allows a variable upgrade due to control dependence, but marks the variable "partially-leaked". The program is stopped later if it tries to use the partially-leaked variable. Permissive-upgrade handles the dead-variable assignment problem and remains sound. However, Austin and Flanagan develop permissive-upgrade only for a two-point (low-high) security lattice and indicate a generalization to pointwise products of such lattices. In this paper, we develop a non-trivial and non-obvious generalization of permissive-upgrade to arbitrary lattices. The key difficulty lies in finding a suitable notion of partial leaks that is both sound and permissive and in developing a suitable definition of memory equivalence that allows an inductive proof of soundness.

description: High quality Rb0.8Fe1.6+xSe2 single crystals are grown by a one step melting growth method. Superconductivity has been observed in all samples with x more than 0.05 and the maximum critical temperature Tc~32 K has been obtained in samples with x from 0.1 to 0.2 from electronic resistivity measurement. A superconducting dome in the electronic phase diagram of Tc as a function of Fe content has been observed for the first time in this AxFeySe2 (A=K,Rb) superconducting system. Two coexisting phases with structural modulation vectors of q1=1/5 [3a*+b*] and q2=1/2[a*+b*] have been observed in all superconducting samples by TEM observations. Moreover, phase separation in the superconducting crystals, which can be recognized as micro-stripes in the ab plane, are found to be highly dependent on the Fe content.

Collection development in public libraries

description: The purpose of this study is to analyze collection development policies in public libraries in North Carolina in order to illuminate the current status of these policies in the state. Methods included a documentation review and content analysis of the collection development policies of public libraries in North Carolina. The policies were checked against a list of aspects recommended in the literature. Results indicate that the current state of the policies reflects the complaint from policy opponents that these types of policies are often not written well enough to be maintained and useful in practice by librarians. There is not an existing standard with minimum guidelines in place for constructing these policies.
Starobinsky-Type Inflation from $α'$-Corrections

description: Working in the Large Volume Scenario (LVS) of IIB Calabi-Yau flux compactifications, we construct inflationary models from recently computed higher derivative $(α')^3$-corrections. Inflation is driven by a Kaehler modulus whose potential arises from the aforementioned corrections, while we use the inclusion of string loop effects just to ensure the existence of a graceful exit when necessary. The effective inflaton potential takes a Starobinsky-type form $V=V_0(1-e^{-νϕ})^2$, where we obtain one set-up with $ν=-1/\sqrt{3}$ and one with $ν=2/\sqrt{3}$ corresponding to inflation occurring for increasing or decreasing $ϕ$ respectively. The inflationary observables are thus in perfect agreement with PLANCK, while the two scenarios remain observationally distinguishable via slightly varying predictions for the tensor-to-scalar ratio $r$. Both set-ups yield $r\simeq (2\ldots 7)\,\times 10^{-3}$. They hence realise inflation with moderately large fields $\left(Δϕ\sim 6\thinspace M_{Pl}\right)$ without saturating the Lyth bound. Control over higher corrections relies in part on tuning underlying microscopic parameters, and in part on intrinsic suppressions. The intrinsic part of control arises as a leftover from an approximate effective shift symmetry at parametrically large volume.

Exploring the Image of the Librarian through Themes of Identity and Self

description: This paper will explore themes of identity and self as a means of creating a unified identity or multiple information identities for librarians. This paper is being written in response to historical and current literature surrounding the image of the librarian, particularly negative stereotypes.  By examining library literature and themes of image, identity, and self, librarians will begin to create identities that will allow them to be recognized by the public as information specialists, educators, and authoritative guides to paths of inquiry. Where yesterday's image of librarians came to be silent stereotypes and shadowy misconceptions, today's librarians are dissatisfied voices too caught up in the language of dissatisfaction to go beyond this stereotype. Tomorrow's librarians must be free to move ahead into roles they have defined for themselves. Exploring principles of the learning process by Jerome Bruner, Lev Vygotsky, and Frank Smith will enable librarians to identify and address patron learning needs in more active ways. By becoming more mindful of the desire for a coherent narrative, as well as by allowing for individual cognitive styles, the librarian will enrich and heighten the patron's learning experience.

description: Band gap engineering in SrTiO${}_{3}$ and related titanate perovskites has long been explored due to the intriguing properties of the materials for photocatalysis and photovoltaic applications. A popular approach in the materials chemistry community is to substitutionally dope aliovalent transition metal ions onto the B site in the lattice to alter the valence band. However, in such a scheme there is limited control over the dopant valence, and compensating defects often form. Here we demonstrate a novel technique to controllably synthesize Fe$^{2+}$- and Fe$^{3+}$-doped SrTiO${}_{3}$ thin films without formation of compensating defects by co-doping with La$^{3+}$ ions on the A site. We stabilize Fe$^{2+}$-doped films by doping with two La ions for every Fe dopant, and find that the Fe ions exhibit a low-spin electronic configuration, producing optical transitions in the near infrared regime and degenerate doping. The novel electronic states observed here offer a new avenue for band gap engineering in perovskites for photocatalytic and photovoltaic applications.

description: The information seeking behavior and skills of the private investigator are typical of many other information professionals, but the high risk information (HRI) they deal with, and the particular skills needed to work with and find this particular type of information, especially in regards to today's information privacy concerns, make this group an ideal subject for study. For this study, four private investigative agencies were observed and/or interviewed in North Carolina and Georgia. The purpose of this research is twofold: 1) to discover what information seeking strategies are used by private investigators, and 2) to understand which barriers affect their search process. Results indicate that private investigators rely heavily on fee-based databases to save time during an investigation and save the client money. They must also be excellent communicators, as a large portion of their time is spent on the phone and conducting investigative interviews. Results also show that unlike with other information professional groups, deception plays a larger role in the work of the private investigator.

description: This paper is devoted to the study of metric subregularity and strong subregularity of any positive order $q$ for set-valued mappings in finite and infinite dimensions. While these notions have been studied and applied earlier for $q=1$ and---to a much lesser extent---for $q\in(0,1)$, no results are available for the case $q>1$. We derive characterizations of these notions for subgradient mappings, develop their sensitivity analysis under small perturbations, and provide applications to the convergence rate of Newton-type methods for solving generalized equations.

description: This paper traces the growth of digital preservation and access programs, and the institutional structures created to preserve them, in the Cornell University Library system. The paper is a case study, tracing the transition from a series of individual projects to an institutional approach that has made Cornell a leader in the field. This approach provides for both the preservation of collections already created and for the establishment of standards to assist in the development of further work in this field. The staff of the Cornell University Library system has made use of the opportunities presented by digital and network technology to augment the library's traditional role of preserving and providing access to scholarly materials. They have forged cooperative relationships among various segments of the university, as well as corporate and governmental partners. Finally, they have taken a proactive approach to the establishment of best practices for digitization programs.

description: Small ball inequalities have been extensively studied in the setting of Gaussian processes and associated Banach or Hilbert spaces. In this paper, we focus on studying small ball probabilities for sums or differences of independent, identically distributed random elements taking values in very general sets. Depending on the setting--abelian or nonabelian groups, or vector spaces, or Banach spaces--we provide a collection of inequalities relating different small ball probabilities that are sharp in many cases of interest. We prove these distribution-free probabilistic inequalities by showing that underlying them are inequalities of extremal combinatorial nature, related among other things to classical packing problems such as the kissing number problem. Applications are given to moment inequalities.

Using the next-to-leading order renormalization group equations, we address the questions of vacuum stability and the hierarchy problem in the context of the mentioned Two-Higgs-Doublet models.

description: We study the pairwise quantum discord (QD) for a symmetric multi-qubit system in different types of noisy channels, such as phase-flip, amplitude damping, phase-damping, and depolarizing channels. Using the QD and geometric measure of quantum discord (GMQD) to quantify quantum correlations, some analytical or numerical results are presented. The results show that, the dynamics of the pairwise QD is related to the number of spin particles $N$ as well as initial parameter $θ$ of the one-axis twisting collective state. With the number of spin particles $N$ increasing, the amount of the pairwise QD increases. However, when the amount of the pairwise QD arrives at a stable maximal value, the pairwise QD is independence of the number of spin particles $N$ increasing. The behavior of the pairwise QD is symmetrical during a period $0\leq θ\leq 2π$. Moreover, we compare the pairwise QD dynamics with the GMQD for a symmetric multi-qubit system in different types of noisy channels.

description: This paper discusses the inherent problems facing librarians who deal with legal reference situations. These problems include (1) the potential for malpractice lawsuits, is there a precedent, and how feasible is a malpractice suit. (2) The lack of definition for the term unauthorized practice of law, why it remains undefined, and how it affects provision of reference service. (3) Debate over the assistance librarians may give and who determines where that level lays. (4) Discussion not only of the lack of library policy but what a policy should try to address and how to approach the problem. These items are all important for both institutions and individual librarians to keep in mind as the occurrence of legal reference inquiries at any reference desk, not just a law library, is rising.

description: This research reports on the findings of a study of archival processing in medical center archives, health sciences collections, and history of medicine collections. This exploratory study examined how archivists in these settings process collections and, in so doing, how they balance the potentially conflicting needs of protecting privacy and providing timely access. Four practicing archivists were interviewed, the interviews were transcribed, and data were coded inductively. Participants addressed how they identified sensitive information scattered throughout collections, the impact this sensitive information had on processing decisions, how they communicated access restrictions, and ways in which they managed access. The findings suggest that sensitive information is best protected when it becomes a shared commitment and a shared responsibility between all groups involved.

A standard table-browsing environment is provided in the form of Java applet which can be opened in any web browser such as Netscape, or Internet Explore with Java 1.2 plug-in installed.  Some manipulation functions to tables are supported for various level of objects in table (table, sub-table, column, row, cell).  A hierarchical Java tree provides the table of content (TOC) of available tables.  Three tier architecture is used in jTBX system design.  Remote database tier provides raw data from distributed sites.  Web server tier generates the response in the standard XML format to the requests from the client side tier (table browser).  Metadata for tables are integrated into the XML files (or streams) before being used by client Java applet.  Multiple threads are generated for a large table transporting.

description: Proper classification of specimens is vital for electronic repositories that maintain information about biological subjects. Using multiple taxonomic authorities' concepts to classify specimens and identify flora information creates ambiguities during the handling of the records. The University of North Carolina Herbarium Flora of the Southeast website faces the same challenges as it is providing its users flora distribution information from multiple data sources. This paper presents the research and development work conducted to re-design the Flora of the Southeast website and its databases to allow for the use of multiple taxon authorities with their versioning with minimal ambiguity. The results support a design that recommends the databases to be built upon standards-based schemas and to be utilizing both the VegBank XML and TDWG's Taxonomic Concept Transfer Schema as guidelines.

Codes of Best Practices and Decision-Making on Fair Use Questions in Academic Libraries
Creators: name: Pinault, Emma
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 2013
Subjects: Fair use (Copyright)
Library copyright policies
Academic libraries--Law & legislation

description: This study describes the results of an email survey sent to 79 academic librarians at institutions of a similar level of research activity, designed to examine attitudes toward fair use and awareness of the Association of Research Libraries' recently published Code of Best Practices in Fair Use for Academic and Research Libraries. Results showed that slightly more than half of respondents had read the Code. Those who had read it were likely to agree that it was relevant and useful to their library's mission, but they did not report relying on fair use in copyright-related decision making at a higher rate than those who had not.

Reference Service--Academic library

description: This study assesses the current environment of electronic database services at the University of North Carolina-Chapel Hill. User patterns, reactions to the new service, "Subject Listings of Selected Electronic Indexes and Databases," level of satisfaction with electronic databases and training/instruction program issues are presented based on a survey of selected UNC users. The results reveal that users are moderately satisfied with the current electronic services. Several interesting facts were found through this research. More than 70% of the survey respondents would like to have an instruction/training program. Online screen help is the most desired type of training indicated by those surveyed. Still, a majority of users (43%) are seeking the help of reference librarians. In addition, finding the appropriate database is mentioned by users as the biggest issue in the area of research.  Finally, the findings of this study emphasize and challenge the role of the reference librarians as an information manager as well as an educator.
A linear-scaling source-sink algorithm for simulating time-resolved quantum transport and superconductivity

Subjects: subject: Superconductivity (cond-mat.supr-con)

subject: FOS: Physical sciences

description: We report on a "source-sink" algorithm which allows one to calculate time-resolved physical quantities from a general nanoelectronic quantum system (described by an arbitrary time-dependent quadratic Hamiltonian) connected to infinite electrodes. Although mathematically equivalent to the non equilibrium Green's function formalism, the approach is based on the scattering wave functions of the system. It amounts to solving a set of generalized Schrödinger equations which include an additional "source" term (coming from the time dependent perturbation) and an absorbing "sink" term (the electrodes). The algorithm execution time scales linearly with both system size and simulation time allowing one to simulate large systems (currently around $10^6$ degrees of freedom) and/or large times (currently around $10^5$ times the smallest time scale of the system). As an application we calculate the current-voltage characteristics of a Josephson junction for both short and long junctions, and recover the multiple Andreev reflexion (MAR) physics. We also discuss two intrinsically time-dependent situations: the relaxation time of a Josephson junction after a quench of the voltage bias, and the propagation of voltage pulses through a Josephson junction. In the case of a ballistic, long Josephson junction, we predict that a fast voltage pulse creates an oscillatory current whose frequency is controlled by the Thouless energy of the normal part. A similar effect is found for short junctions, a voltage pulse produces an oscillating current which, in the absence of electromagnetic environment, does not relax.

description: This paper discusses the major results and conclusions derived from the open-ended questions analysis, which was part of a 28 questions survey (25 close-ended questions, 3 open-ended questions) on academic scientist's information seeking behavior (ISB) and information use (IU) conducted at the University of North Carolina-Chapel Hill (UNC-CH) during the Spring of 2005. The university's academic scientists were asked to provide written responses expressing their perceptions about UNC-CH library and information services. The three open-ended questions were: (1) what are the positive aspects of service, (2) what are the shortcomings, and (3) what is one wish for future services (Hemminger, 2007). Nine-hundred sixty-nine (969) participants completed the survey. The participant comments were used to create a coding/classification schema of library services. Interactive Comment in Schema (ICIS), an interactive, web-based visualization tool, was created for displaying, analyzing, and sharing participant feedback among the university's librarians.
