    Authors: Lutolf, Matthias P.; Blau, Helen M.;

    Stem cells are characterized by their dual ability to self- renew and differentiate, yielding essentially unlimited numbers of progeny that can replenish tissues with either high turnover such as blood and skin or contribute to the regeneration of organs with less frequent remodeling such as muscle. In contrast to their embryonic counterparts, adult stem cells can only preserve their unique functions if they are in intimate contact with an instructive microenvironment, termed niche. Stem cells integrate a complex array of niche signals that regulate their fate, keeping them in a relatively quiescent state during homeostasis, or controlling their numbers via symmetric or asymmetric divisions in response to the regenerative demands of a tissue. This chapter provides an overview of the current state of knowledge of structural and functional hallmarks of mammalian stem cell niches and offers a perspective on how bioengineering principles could be used to deconstruct the niche and providing novel insights into the role of its specific components in the regulation of stem cell fate. Such “artificial niches” constitute powerful tools for elucidating stem cell regulatory mechanisms that should fuel the development of novel therapeutic strategies for tissue regeneration.

  • A cross-disciplinary academic team at Emporia State University is currently in the process of developing and utilizing a mobile-based augmented reality application in the context of library information search. Specifically, the team is researching the use of mobile applications that can generate multi-sensory information retrieval relative to archives and special collections. Using this application, student and faculty researchers can physically point their mobile devices at an archival object that has been specifically marked with a photo-generated “tag” and, using specially designed software, access videos, photos, music, text, and other data that is germane to the object. This allows the archivist to preserve the object behind protective glass or other physical barriers, while allowing the information seeker to learn more about the object using embedded multimedia. This minimizes the potential for damage while providing extra dimensions of information. Of the many virtualizations currently under development are videos related to a rare novel and music compositions relative to rare sheet music – both currently housed within Special Collections at Emporia State University.

    In this paper, we propose a multi-view learning method using Magnetic Resonance Imaging (MRI) data for Alzheimer’s Disease (AD) diagnosis. Specifically, we extract both Region-Of-Interest (ROI) features and Histograms of Oriented Gradient (HOG) features from each MRI image, and then propose mapping HOG features onto the space of ROI features to make them comparable and to impose high intra-class similarity with low inter-class similarity. Finally, both mapped HOG features and original ROI features are input to the support vector machine for AD diagnosis. The purpose of mapping HOG features onto the space of ROI features is to provide complementary information so that features from different views can not only be comparable (i.e., homogeneous) but also be interpretable. For example, ROI features are robust to noise, but lack of reflecting small or subtle changes, while HOG features are diverse but less robust to noise. The proposed multi-view learning method is designed to learn the transformation between two spaces and to separate the classes under the supervision of class labels. The experimental results on the MRI images from the Alzheimer’s Disease Neuroimaging Initiative (ADNI) dataset show that the proposed multi-view method helps enhance disease status identification performance, outperforming both baseline methods and state-of-the-art methods.

    Surface analysis of thin film ITO heat mirror coatings on glass was performed using SAM, ESCA, and TEM. Reactive evaporation of In-5wt%Sn was used to produce ITO films which had excellent infrared reflectivity and visible transmissivity. Oxide films 300–900A thick were produced by evaporation of In-5wt%Sn in a controlled oxygen atmosphere on substrates between 25–300°C. Some evidence of Sn surface segregation was noted, and an increase in film continuity with an increase in oxygen pressure was found.

    Authors: H.J. Saz;

    Antibiotic inhibitors of macromolecular synthesis generally have been without chemo-therapeutic effect in helminth diseases, since not only reproduction must be inhibited, but also the adult stage itself must be removed from the host. Many anthelmintics seem to act by altering motility. This is accomplished by affecting either neuromuscular transmission or metabolic energy generation. All parasitic helminths, and most of the parasitic protozoa, differ from their hosts metabolically in that they are not capable of oxidizing substrates completely to CO2 and H2O. All of them examined accumulate other end products, indicating the lack of, or a limited, terminal respiration. This applies to aerobic as well as to “micro-aerophillic” or “anaerobic” helminths, and is independent of the environment within the host. For example, Schistosoma mansoni and Brugia pahangi are both homolactate fermenters in spite of their aerobic environment in the host. Litomosoides carinii, on the other hand, is highly oxygen dependent for survival, but appears to use this oxygen for the single step oxidative decarboxylation of pyruvate to form acetate. Ascaris lumbricoides var. suum has served as a model system for many other helminths, invertebrates, deep diving fish and mammals which accumulate succinate or products derived from succinate during their life cycles. It is now well established that succinate is formed via a pathway involving CO2 fixation into phosphoenolpyruvate followed by a mitochondrial dismutation reaction involving an oxidation to pyruvate and a reduction to succinate. The fumarate reductase reaction is coupled to an anaerobic electron transport associated generation of ATP. Some anthelmintic agents act by uncoupling this phosphorylation, while others appear to inhibit fumarate reductase and still others inhibit the uptake of substrates or affect the breakdown of glycogen. Recent studies will be described pertaining to additional possible sites of ATP generation in the Ascaris mitochondria. These include: (1) the anaerobic oxidative decarboxylation of pyruvate to acetyl CoA; (2) reduction of the C5 unsaturated 2-methylcrotonate (tiglate) by NADH to form a major fermentation product of Ascaris metabolism, 2-methylbutyrate; and (3) a substrate level phosphorylation associated with the decarboxylation of succinate to propionate according to the following reactions:

    Authors: Dan M. Somers;

    From its very beginning, the National Advisory Committee for Aeronautics (NACA) recognized the importance of airfoils as a cornerstone of aeronautical research and development. In its first Annual Report to the Congress of the United States, the NACA called for “the evolution of more efficient wing sections of practical form, embodying suitable dimensions for an economical structure, with moderate travel of the center of pressure and still affording a large range of angle of attack combined with efficient action” (Ref. 1). By 1920, the Committee had published a compendium of experimental results from various sources (Ref. 2). Shortly thereafter, the development of airfoils by the NACA was initiated at the Langley Memorial Aeronautical Laboratory (Ref. 3). The first series of airfoils, designated “M sections” for Max M. Munk, was tested in the Langley Variable-Density Tunnel (Ref. 4). This series was significant because it represented a systematic approach to airfoil development as opposed to earlier, random, cut-and-try approaches. This empirical approach, which involved modifying the geometry of an existing airfoil, culminated in the development of the four- and five-digit-series airfoils in the mid 1930’s (Refs. 5–7).

    It has long been generally accepted that 244Pu fission xenon is absent in lunar fines, while carbonaceous chondrites contain the so-called xenon-HL, which is a strange fission-like xenon component, whose isotopic composition is different from that of the 244Pu fission xenon. Re-examination of a vast amount of existing xenon isotope data reveals, however, that lunar fines and carbonaceous chondrites both contain appreciable amounts of 244Pu fission xenon and they began to retain their xenon almost 5.1 billion years ago, when the 244Pu to 238U ratio in the solar system was roughly 1 to 2 (atom/atom). In the present paper, re-examination of the experimental data is extended to the lead/lead and potassium/argon dating methods.

    Eudicots are an important and well-supported monophyletic group of angiosperms. The clade includes almost all dicotyledons; the only groups excluded are eumagnoliids and those dicots at the ANITA grade plus Chloranthaceae and Ceratophyllum . Eudicots are therefore broadly equivalent to all dicot lineages except the Magnoliidae sensu Takhtajan (1980) (Chapter 7). The term eudicotyledons, or eudicots, was introduced to recognise the monophyletic status of this major group (Doyle and Hotton, 1991), and has been widely accepted in subsequent works. Earlier studies referred to eudicots as non-magnoliid dicots (Walker and Doyle, 1975; Crane, 1989) or tricolpates (Donoghue and Doyle, 1989b; Judd and Olmstead, 2004). The term tricolpates refers to the tricolpate aperture configuration, which is characteristic of the pollen of many early-diverging eudicots. While many eudicots have pollen with other aperture configurations, almost all are based on the triaperturate ground plan (Doyle and Hotton, 1991). Eudicots are extremely diverse, and exhibit an almost bewildering breadth of morphological and ecological variation. The group contains about three-quarters of all extant angiosperm species (Magallon et al ., 1999). The fossil record of eudicots is extensive and informative about their evolutionary history. In this chapter we provide a brief outline of eudicot classification and the early fossil record of the group. We then focus on those lineages that diverged at an early stage from the line that gave rise to the bulk of eudicot species. We emphasise particularly the Cretaceous fossil record, and those taxa that can be recognised based on fossil flowers or other reproductive organs.

    Authors: Lutolf, Matthias P.; Blau, Helen M.;

    Stem cells are characterized by their dual ability to self- renew and differentiate, yielding essentially unlimited numbers of progeny that can replenish tissues with either high turnover such as blood and skin or contribute to the regeneration of organs with less frequent remodeling such as muscle. In contrast to their embryonic counterparts, adult stem cells can only preserve their unique functions if they are in intimate contact with an instructive microenvironment, termed niche. Stem cells integrate a complex array of niche signals that regulate their fate, keeping them in a relatively quiescent state during homeostasis, or controlling their numbers via symmetric or asymmetric divisions in response to the regenerative demands of a tissue. This chapter provides an overview of the current state of knowledge of structural and functional hallmarks of mammalian stem cell niches and offers a perspective on how bioengineering principles could be used to deconstruct the niche and providing novel insights into the role of its specific components in the regulation of stem cell fate. Such “artificial niches” constitute powerful tools for elucidating stem cell regulatory mechanisms that should fuel the development of novel therapeutic strategies for tissue regeneration.

  • A cross-disciplinary academic team at Emporia State University is currently in the process of developing and utilizing a mobile-based augmented reality application in the context of library information search. Specifically, the team is researching the use of mobile applications that can generate multi-sensory information retrieval relative to archives and special collections. Using this application, student and faculty researchers can physically point their mobile devices at an archival object that has been specifically marked with a photo-generated “tag” and, using specially designed software, access videos, photos, music, text, and other data that is germane to the object. This allows the archivist to preserve the object behind protective glass or other physical barriers, while allowing the information seeker to learn more about the object using embedded multimedia. This minimizes the potential for damage while providing extra dimensions of information. Of the many virtualizations currently under development are videos related to a rare novel and music compositions relative to rare sheet music – both currently housed within Special Collections at Emporia State University.

    In this paper, we propose a multi-view learning method using Magnetic Resonance Imaging (MRI) data for Alzheimer’s Disease (AD) diagnosis. Specifically, we extract both Region-Of-Interest (ROI) features and Histograms of Oriented Gradient (HOG) features from each MRI image, and then propose mapping HOG features onto the space of ROI features to make them comparable and to impose high intra-class similarity with low inter-class similarity. Finally, both mapped HOG features and original ROI features are input to the support vector machine for AD diagnosis. The purpose of mapping HOG features onto the space of ROI features is to provide complementary information so that features from different views can not only be comparable (i.e., homogeneous) but also be interpretable. For example, ROI features are robust to noise, but lack of reflecting small or subtle changes, while HOG features are diverse but less robust to noise. The proposed multi-view learning method is designed to learn the transformation between two spaces and to separate the classes under the supervision of class labels. The experimental results on the MRI images from the Alzheimer’s Disease Neuroimaging Initiative (ADNI) dataset show that the proposed multi-view method helps enhance disease status identification performance, outperforming both baseline methods and state-of-the-art methods.
