    Abstract:

    The use of Gigapan imagery in an archaeological context allows for quick, very high resolution recording of excavation surfaces, artifacts and surrounding areas. At the Paleolithic site of Abri Castanet (France), we have, since 2008, used a Gigapan imager mounted horizontally to record lateral variation across our active excavation surface. Using GIS software and topographic data from our onsite Total Station, we can then minimize distortion, plot the image relative to artifact and feature lo…

    Abstract:

    This paper considers what can be accomplished using a mobile robot that has limited sensing. For navigation and mapping, the robot has only one sensor, which tracks the directions of depth discontinuities. There are no coordinates, and the robot is given a motion primitive that allows it to move toward discontinuities. The robot is incapable of performing localization or measuring any distances or angles. Nevertheless, when dropped into an unknown planar environment, the robot builds a data s…

    Abstract:

    This article describes a digital library framework and toolkit called MyLibrary. At its heart, MyLibrary is designed to create relationships between information resources and people. To this end, MyLibrary is made up of essentially four parts: (1) information resources, (2) patrons, (3) librarians, and (4) a set of locally defined, institution-specific facet/term combinations interconnecting the first three. On another level, MyLibrary is a set of object-oriented Perl modules intended to read…

    Abstract:

    This article describes the design and implementation of two digital library collections and services using a number of “light-weight” protocols and open source tools. These protocols and tools include OAI-PMH (Open Archives Initiative-Protocol for Metadata Harvesting), SRU (Search/Retrieve via URL), Perl, MyLibrary, Swish-e, Plucene, ASPELL, and WordNet. More specifically, we describe how these protocols and tools are employed in the Ockham Alerting service and MyLibrary@Ockham. The…

    Abstract:

    By reverse engineering Google queries and by tracing back the referrer values found in Apache log files, the use of images made available from infomotions.com is examined. Ethical and economic questions questions are then asked. While all the images from the site are “freely” available under the GNU Public License, they are not always used in the intended manner. This raises interesting questions regarding the time spent making the images available, the expense of the hardware and network con…

    Abstract:

    The “Origin of Modern Humans”, the “Great Leap Forward”, the “Human Revolution" –are but a few of the terms used to describe the Upper Paleolithic Period in Europe (45,000-11,000 BP). There, and in and contiguous parts of western Asia, the Upper Paleolithic Period preserves the first consistent evidence for several distinctively human behaviors (i.e., behaviors that appear to have evolved uniquely among Homo sapiens). These behaviors include systematic production of personal ornaments,…

    Abstract:

    Despite a body of literature focusing on the functionality of modern and stylistically distinct projectile points, comparatively little attention has been paid to quantifying the functionality of the early stages of projectile use. Previous work identified a simple ballistics measure, the Tip Cross-Sectional Area, as a way of determining if a given class of stone points could have served as effective projectile armatures. Here we use this in combination with an alternate measure, the Tip Cros…

    Abstract:

    This paper proposes that complex projectile weaponry was a key strategic innovation driving Late Pleistocene human dispersal into western Eurasia after 50 Ka. It argues that complex projectile weapons of the kind used by ethnographic hunter-gatherers, such as the bow and arrow, and spearthrower and dart, enabled Homo sapiens to overcome obstacles that constrained previous human dispersal from Africa to temperate western Eurasia. In the East Mediterranean Levant, the only permanent land bridge…

    Abstract:

    A web-based survey of book conservation treatment practices in research libraries was conducted in 2007. Survey results were summarized in a 2010 report that documented standard practice, moderate-use, and low-use book conservation treatments for special collections and general collections in research libraries in the United States. Similarities and differences between special and general collections practices were highlighted. In an effort to better understand the differences in practices ob…

    The field of research library conservation has emerged as a distinct discipline and undergone major refinements over the past fifty years: professional organizations and training programs have been established, new treatment techniques have been developed and promoted, and, increasingly, special and general collections practitioners have collaborated on treatment solutions. Despite such dramatic growth and definition within the field, there has been no comprehensive assessment of the book tre…

    Abstract:

    Copying pencils present a significant hazard to conservators. Their markings are easily mistaken for those of standard graphite pencils, and they generally contain a dye that is water and alcohol soluble. To those unacquainted with copying pencils, their discovery might come as an unwelcome surprise during a routine wet treatment wherein copying pencil markings were mistaken for standard graphite. In order to familiarize conservators with this deceptive medium, this article describes the comp…

    What follows is an example of such hybrid, computationally assisted scholarship.

    Abstract:

    Human settlement is guided by a suite of economic and social decisions. Hunter-gatherer populations are not restricted by extensive ownership and often focus settlement on important resources. Analysis of settlement patterns left by these groups reveals key information about subsistence and sociality. Patterning among modern groups is extremely varied and represents a dynamic and adaptable land-use strategy. The antiquity of this adaptability is unknown, but comparisons with the patterns left…

    Abstract:

    Computational reproducibility depends on being able to isolate necessary and sufficient computational artifacts and preserve them for later re-execution. Both isolation and preservation of artifacts can be challenging due to the complexity of existing software and systems and the resulting implicit dependencies, resource distribution, and shifting compatibility of systems as time progresses—all conspiring to break the reproducibility of an application. Sandboxing is a technique that has bee…

    Review of the book Using the Mathematics Literature, edited by Kristine K. Fowler, New York, Marcel Dekker, 2004. 389 pp., US $165, ISBN 0-8247-5035-7.

    The book’s major drawback is its price—42 cents per page vs. 19 cents for Tucker and Anderson. However, it is still an important addition to your library’s collection, a relevant resource for undergraduate and graduate student advisors, and perhaps a gift for the new librarian who will be working with your department.

    Faculty/librarian collaboration is vital for librarians to remain integral to the academy. We now have an opportunity to change how we perceive ourselves and how we are perceived by faculty and administrators. There are viable solutions for expanding the role of the librarian in ways that could lead to better faculty partnerships. First, librarians must be grounded in a shared purpose and professional identity and establish a contextual framework for our own professional ‘boundaries.’ We cann…

    How many monographs acquired in a particular year circulate in that year? What percentage have their first circulation each successive year? Does the pattern differ for different broad subject areas, i.e., humanities, the sciences, and the social sciences? This article tests the assumption that the first-circulation pattern differs by subject. We conclude that the pattern does not differ. The finding is important for decisions about off-site storage, assessing collection development, maintain…

    Abstract:

    The genome assembly of southern house mosquito Cx. quinquefasciatus is represented by a high number of supercontigs with no order or orientation on the chromosomes. Although cytogenetic maps for the polytene chromosomes of this mosquito have been developed, their utilization for the genome mapping remains difficult because of the low number of high-quality spreads in chromosome preparations. Therefore, a simple and robust mitotic-chromosome-based approach for the genome mapping of Cx. quinque…

    Dengue virus is primarily transmitted by Aedes aegypti mosquitoes. Control of the vector mosquito is the major practice to prevent dengue. However, it is not well known how the virus can infect some mosquito strains but fail to do so with other refractory strains. To address that question, we conducted whole genome microarray based gene expression studies between susceptible and refractory strains of A. aegypti to identify gene expression patterns following challenge with dengue virus. Our an…

    Background: The slowest reaction in the first CNO cycle is 14N(p,γ ) 15O, therefore its rate determines the overall energy production efficiency of the entire cycle. The cross section presents several strong resonance contributions, especially for the ground-state transition. Some of the properties of the corresponding levels in the 15O compound nucleus remain uncertain, which affects the uncertainty in extrapolating the capture cross section to the low energy range of astrophysical interest….

We introduce a method for automatically adjusting network size by pruning out hidden units through L∞,1 and L2,1 regularization. We apply this method to language mo…

The application of the term diaspora to people of Irish descent living outside Ireland is, after all, of relatively recent date and replaces a term that has been quite resonant in the Irish vocabular…

    Path tracking is the fundamental computational tool in homotopy continuation and is therefore key in most algorithms in the emerging field of numerical algebraic geometry.

In this article, the effects of the choice of predictor method on the performance of a tracker is analyzed, and details for…

    Abstract:

    Numerical algebraic geometry is the area devoted to the solution and manipulation of polynomial systems by numerical methods, which are mainly based on continuation. Due to the extreme intrinsic parallelism of continuation, polynomial systems may be successfully dealt with that are much larger than is possible with other methods. Singular solutions require special numerical methods called endgames, and the endgames currently used do not take advantage of parallelism. This article gives an ove…

    Dedicated to our collaborator, mentor, and friend, Andrew Sommese, by Bates, Hauenstein, and Wampler on the occasion of his sixtieth birthday.

    When numerically tracking implicitly-defined paths, such as is required for homotopy continuation methods, efficiency and reliability are enhanced by using adaptive stepsize and adaptive multiprecision methods. Both efficiency and reliability can be further improved by adapting precision and stepsize simultaneously. This paper presents a strategy fo…

    Abstract:

    Whereas union leaders in nineteenth-century America often used the phrase “a living wage” to describe appropriate compensation for skilled workers, today that phrase is typically linked to unskilled labor. I argue that the erosion of ties between skilled workers and the living wage occurred in several stages between 1900 and 1930. Having traditionally avoided quantifying the “living wage,” unions were forced to do so within arbitration hearings, especially as these proliferated during and aft…

Revealing these ruptures produces a more accurate history of both the development of neoclassical price index theory and its reception. Furthermore, we can recognize how transformations in this theory have made cost-of-living in…

Economists conducting expenditure surveys faced one fundamental concern: their success hinged upon the cooperation of interviewees (typically housewives) and the reliability of their testimony. Investigators recognized that both dependencies posed serious problems, and they struggled to devise effective solutions. I argue that over the course of the twentieth cent…

    Abstract:

    Prior to the 1960s most American economists rejected hedonic techniques as a solution to the problem of quality change in price indexes. I argue that behind that judgment lay a deeper conceptual divide over how best to define and assess product quality: through expert testing or through market price differentials. Most American economists working on price indexes at the time had ties to the U.S. consumer movement, which emphasized consumer ignorance and promoted expert analysis as the only re…

    Abstract:

    This essay explores the history of the 1935-1936 Study of Consumer Purchases, an extraordinary national survey of family incomes and expenditures undertaken by the federal government during the New Deal. Created and administered primarily left-leaning economists, the project was an order of magnitude larger and more complex than any previous expenditure survey and was intended to aid and justify state-led economic planning. Yet it failed to be an effective help to New Deal reformers, proving …

    Editor’s Summary: Scholarly research is at the forefront of innovation, especially with a breadth of new technologies that can enhance the research process. However, in a race for scholars to produce more and more new findings, documentation practices and reproduction of results may be neglected. Lack of validation through reproduction can lead to a general distrust of scholarly research and experiments, but a more generous approach to information sharing could be the answer to this issue…

    Developing normative indicators to measure governments’ consent to, compliance with, and promotion of international laws prohibiting genocide, war crimes, crimes against humanity, and other norms constituting the International Criminal Court (ICC) demonstrates that it is possible to calibrate variation in state conduct over time and to compare one state to another. The indicators make compliance more visible and amenable, both to encouragement by nongovernmental organizations and states, and …

    Abstract:

    From 1910 - 1940, the practice of business and the practice of economics came to inform one another in novel ways, a reconfiguration that included the emergence of econometrics. The core locus for this intersection came from the rise of commercial forecasting—whether analyses of future demand, price and cost fluctuations, or financial markets—based on the analysis of statistical data. Forecasting united a suite of specific interactions with the practice of economics: business support for the …

    Abstract:

    “Practice” has become a ubiquitous term in the history of science, and yet historians have not always reflected on its philosophical import and especially on its potential connections with ethics. In this essay, we draw on the work of the virtue ethicist Alasdair MacIntyre to develop a theory of “communal practices” and explore how such an approach can inform the history of science, including allegations about the corruption of science by wealth or power; consideration of scientific ethics or…

    Hesburgh Libraries of Notre Dame established an off-site storage facility in 2015, with only one year to transfer 450,000 items. This necessitated the implementation of an inventory management system (IMS) to track the location of and efficiently retrieve individual items. After conducting an environmental scan of other institutions, the library decided to develop an open source IMS and to contract a developer for the purposes of implementing a working prototype. Working with a contractor req…

    Confusion and frustration are two of the emotions often felt by undergraduates when they are expected to do library research. They do no know where to start, and are unable to select appropriate terms or sources to search. Furthermore, instructors overestimate the literature research skills of their students. In CHEM 23201, a required one semester course, we introduced a research strategy worksheet as a way to guide students on things to consider when searching the literature. We assumed that…

    Industrial software systems are often systems of systems (SoS) whose full behavior only emerges at runtime. The systems and their interactions thus need to be continuously monitored and checked during operation to determine compliance with requirements. Many requirements monitoring approaches have been proposed. However, only few of these come with tools that present and visualize monitoring results and details on requirements violations to end users such as industrial engineers. In this tool…

Data released in December 2016 showed that census tract 6 in South Bend had the highest rates of EBLL in the state of Indiana. Because lead exposure can produce significant cognitive and physiological damage even at very low levels of exposure, immediate action was required. Understanding what the epidemiologic profile of lead in SJC was among the first steps taken to address this issue. The St. Joseph Coun…

    Hamilton equations are such that the relation, between the coordinates and momenta at time t and at time t 0, is a contact transformation. Methods of integration of Hamilton equations, which do preserve the contact transformation property are given here. These methods are of first and second order. They are given, for the equation x= f(x,t), then for the case of one degree of freedom, then for the general case. Some of the formulae are implicit.

    The suppression of halide ion exchange between CsPbBr3 and CsPbI3 nanocrystals achieved through capping with PbSO4–oleate has enabled us to deposit different perovskite nanocrystals as aligned arrays on the electrode surfaces without intermixing of species. The electrophoretic deposition of PbSO4–oleate-capped CsPbX3 (X = Cl, Br, I) nanocrystals suspended in hexane solution on mesoscopic TiO2 films allows the design of controlled architecture with single or multiple layers of perovskite films…

    Membrane type 1 matrix metalloproteinase (MT1-MMP, MMP-14) is a transmembrane collagenase highly expressed in metastatic ovarian cancer and correlates with poor survival. Accumulating evidence shows that the cytoplasmic tail of MT1-MMP is subjected to phosphorylation, and this post-translational modification regulates enzymatic activity at the cell surface. To investigate the potential role of MT1-MMP cytoplasmic residue Thr567 phosphorylation in regulation of metastasis-associated behaviors,…

    During epithelial ovarian cancer (EOC) progression, intraperitoneally disseminating tumor cells and multicellular aggregates (MCAs) present in ascites fluid adhere to the peritoneum and induce retraction of the peritoneal mesothelial monolayer prior to invasion of the collagen-rich submesothelial matrix and proliferation into macro-metastases. Clinical studies have shown heterogeneity among EOC metastatic units with respect to cadherin expression profiles and invasive behavior; however, the i…

    Galvanic replacement reactions are widely used in the synthesis of bimetallic nanoshells. Essential to these syntheses is the design of template materials with electrochemical potentials that are low enough to facilitate the replacement of a wide variety of metals. While Cu is an attractive template from this standpoint, it has only rarely been used due to its propensity for oxidation and the associated difficulties in achieving chemically stable colloids. Here, a synthetic scheme is demonstr…

    One intriguing aspect of mixed halide lead perovskites (e.g., CH3NH3PbBrxI3–x) is halide ion segregation when subjected to visible illumination, but this aspect gives rise to the concerns regarding the influence of halide ion movement on the long–term stability and applications. Here, the impact of light illumination on mixed halide hybrid perovskite films was investigated by exposing such films to continuous wavelength laser (25 mW/cm2). It turns out that under illumination the segregated io…

    Combustion synthesis (CS) is a specific approach for fabrication of a variety of advanced materials through use of self-sustaining chemical reactions. Controlling over the microstructure of the material is a key factor in defining the maturity of a technology. In this work, we demonstrate that under specific conditions, morphology and microstructure of the initial reaction media do not change during the CS process. Thus, one may control the microstructure of CS materials by preparing the desi…

The catalysts were characterized by SEM/TEM and BET, XRD, XPS, TGA/DSC, and CO chemisorption. Catalysts prepared by impregnation of Ni(NO3)2·6H2O onto fumed SiO2,…

Here, we report the formation of thin film magnetic TI Bi2MnSe4 with stoichiometric composition…
