From Prototype to Production in Hypermedia Projects. (1991)

Many hypermedia projects exist as small-scale prototypes or so-called proof of concept demonstrations. But full-scale projects that are deployed and maintained In production are scarce, because problems can arise at various points In the project life cycle that cause the project to fail. Problems that arise when the project is started include the lack of realistic expectations and the difficulty of assembling a multidisciplinary project team. Problems that emerge during the design and development phases lnclude few published case studies or design guidelines, poor quality or availability of source information, Inappropriate and underpowered software technology, and uncertainty about Intellectual property Issues. Problems at the deployment and maintenance phases lnclude installed base constraints and Inadequate methods for maintaining the hypermedia system. Not all of these problems are specific to hypermedia projects, but they conspire with the novelty and immaturity of hypermedia to make hypermedia applications hard to design, develop, and deploy successfully.
How can we accelerate dissemination of knowledge and learning? (2017)

The Networked Improvement Learning and Support (NILS) platform is an online tool designed to accelerate the initiation and development of Networked Improvement Communities in a disciplined manner. Its main goal is to promote social, organizational learning through curation and synthesis and tacit to explicit knowledge conversion to facilitate knowledge construction and ownership by the communities regarding improvement practice in education. In this proposal we will discuss the NILS platform, a few use cases, and a plan of analytics development that advances knowledge dissemination and monitors the health status of networks.
Low-voltage operation of Si-based ferroelectric field effect transistors using organic ferroelectrics, poly(vinylidene fluoride–trifluoroethylene), as a gate dielectric (2016)

Abstract Si-based metal–ferroelectric–semiconductor (MFS) capacitors have been fabricated using poly(vinylidene fluoride–trifluoroethylene) [P(VDF–TrFE)] as a ferroelectric gate. The pinhole-free P(VDF–TrFE) thin films with high resistivity were able to be prepared by spin-coating directly onto hydrogen-terminated Si. The capacitance–voltage ( C – V ) characteristics of the ferroelectric gate field effect transistor (FeFET) using this MFS structure clearly show butterfly-shaped hysteresis originating from the ferroelectricity, indicating carrier modulation on the Si surface at gate voltages below 2 V. The drain current–gate voltage ( I D – V G ) characteristics also show counterclockwise hysteresis at gate voltages below 5 V. This is the first report on the low-voltage operation of a Si-based FeFET using P(VDF–TrFE) as a gate dielectric. This organic gate FeFET without any insulator layer at the ferroelectric/Si interface should be one of the promising devices for overcoming the critical issues of the FeFET, such as depolarization field and a decrease in the gate voltage.

Photoelectrochemical water splitting and hydrogen generation by a spontaneously formed InGaN nanowall network (2014)

We investigate photoelectrochemical water splitting by a spontaneously formed In-rich InGaN nanowall network, combining the material of choice with the advantages of surface texturing for light harvesting by light scattering. The current density for the InGaN-nanowalls-photoelectrode at zero voltage versus the Ag/AgCl reference electrode is 3.4 mA cm−2 with an incident-photon-to-current-conversion efficiency (IPCE) of 16% under 350 nm laser illumination with 0.075 W·cm−2 power density. In comparison, the current density for a planar InGaN-layer-photoelectrode is 2 mA cm−2 with IPCE of 9% at zero voltage versus the Ag/AgCl reference electrode. The H2 generation rates at zero externally applied voltage versus the Pt counter electrode per illuminated area are 2.8 and 1.61 μmol·h−1·cm−2 for the InGaN nanowalls and InGaN layer, respectively, revealing ∼57% enhancement for the nanowalls.

Polymorph Generation in Capillary Spaces:  The Preparation and Structural Analysis of a Metastable Polymorph of Nabumetone (2002)

Crystallization studies of nabumetone (4-(6-methoxy-2-naphthalenyl)-2-butanone) performed in capillary tubes yielded a metastable polymorph. The single-crystal X-ray structure of this high-energy form is presented and compared to the structure of the known low-energy form. The metastable form of nabumetone readily converts to the low-energy form in the solid state upon grinding or seeding with the low-energy polymorph. The instability of the metastable form is believed to be due to the presence of weaker C−H···O interactions when compared to the thermodynamically more stable form.
Optimal Crowdsourcing Contests (2012)

We study the design and approximation of optimal crowdsourcing contests. Crowdsourcing contests can be modeled as all-pay auctions because entrants must exert effort up-front to enter. Unlike all-pay auctions where a usual design objective would be to maximize revenue, in crowdsourcing contests, the principal only benefits from the submission with the highest quality. We give a theory for optimal crowdsourcing contests that mirrors the theory of optimal auction design: the optimal crowdsourcing contest is a virtual valuation optimizer (the virtual valuation function depends on the distribution of contestant skills and the number of contestants). We also compare crowdsourcing contests with more conventional means of procurement. In this comparison, crowdsourcing contests are relatively disadvantaged because the effort of losing contestants is wasted. Nonetheless, we show that crowdsourcing contests are 2-approximations to conventional methods for a large family of “regular” distributions, and 4-approximations, otherwise.
THE RESPONSE OF BREWING YEASTS TO ACID WASHING (1989)

Brewing yeasts are inherently resistant to acid washing treatments but, under some conditions this resistance is diminished. Sixteen yeast strains, including both ale and lager strains, have been successfully washed using phosphoric acid (pH 2.1) and, in some cases, sulphuric acid (pH 2.0) or acidified 0.75% w/v ammonium persulphate (pH 2.8). Cell viability, fermentation performance and flocculation/fining behaviour were unaffected. However, changes could be observed in the yeast resulting from the washing treatment. These included alterations of the cell surface, as shown by scanning electron microscopy and leakage of adenosine triphosphate from the cells during the wash. Acid washing is successful provided that, i) food grade acid is used, ii) the acid is chilled before use, iii) the yeast and acid are well mixed, iv) the temperature of the yeast does not exceed 5°C during washing and, v) the yeast is pitched immediately after washing. ‘Unhealthy’ yeast (yeast which has been stored for long periods, heavily contaminated yeast, or yeast from slow fermentations) may respond poorly to acid washing and a shorter washing time, or higher wash pH value should be employed.
La reserva para inversiones en Canarias (1995)

It can be concluded that the eventual beneficial effects on menstrual or menopausal discomfort connected with Cimicifuga and Melbrosia self-medication cannot be explained as a traditional oestrogenic effect as measured in biological experiments.
Conformity of valuable spikes by ombroscopic imaging (2010)

This paper describes a methodology for thin spikes characterization. Nowadays, its evaluation is performed by visual control. We propose a method to measure these spikes at a micrometric scale by using ombroscopic image processing. A spike needs to be mainly conic and its tip must be ogival. The first aspect is evaluated by comparing the spike with an ideal cone based on spike's contour. To find lines supported by contours, we use the Radon transform. However, due to irregular contour, we develop an improvement of this transform based on morphological operators. This way, real segments are found and a correct estimation of an ideal cone can be done. The second aspect is controlled by measuring the radius of the tip which gives both sharpness and regularity of the tip. As the following of the curvature is problematic, we use a morphological skeleton on the contour to obtain a structure similar to a Y. The intersection of these three branches leads to a correct estimation of the circular gauge. An additional filling criterion validates the result. This study is successful as the production is correctly classified and precise measures were obtained both in terms of global characteristics and sharpness.
Neuroimaging studies of cognitive remediation in schizophrenia: A systematic and critical review (2017)

Neuroimaging studies of cognitive remediation in patients with schizophrenia suggest a positive effect on brain functioning in terms of the functional reorganisation of neural networks.
Investigation of BS antenna location for future indoor wireless mm-wave communication systems (2004)

This paper examines the performance of the indoor wireless communications systems in the millimeter wave band and investigates the data transmission rate in terms of base station (BS) antenna locations by using the ray-tracing technique. In order to validate the model, continuous wave (cw) experimental measurements are conducted and have successfully fitted the simulation data. The undertaken scenarios are: ceiling mounted base antenna (CeMBA). carrier mounted base antenna (CoMBA), and wall-mounted base antenna (WMBA). Obstructed Line-Of-Sight is also considered. The data analysis of the simulation demonstrates that the WMBA is the best scenario since its channel exhibits the lowest RMS delay spread.
Astroglial CD38 regulates social memory and synapse formation through SPARCL1 in the medial prefrontal cortex (2021)

Abstract Social behavior is essential for the health, survival and reproduction of animals, yet the role of astrocytes in social behavior is largely unknown. CD38 is critical for social behaviors by regulating oxytocin release from hypothalamic neurons. On the other hand, CD38 is most abundantly expressed in astrocytes especially in the postnatal cortex, and is important for astroglial development. Here, we demonstrate that astroglial CD38 plays a pivotal role in the social behavior. Selective deletion of CD38 in postnatal astrocytes, but not in adult astrocytes, specifically impaired social memory without any other behavioral abnormalities. Morphological analysis revealed reductions in spine numbers, mature spines and excitatory synapse numbers in the pyramidal neurons of the medial prefrontal cortex (mPFC) due to deletion of astroglial CD38 in the postnatal brain. Astrocyte-conditioned medium (ACM) of CD38 KO astrocytes reduced synaptogenesis of cortical neurons by reducing extracellular SPARCL1, a synaptogenic protein. Finally, the release of SPARCL1 from astrocytes is regulated by CD38/cADPR/calcium signaling. Our data indicate that astroglial CD38 developmentally regulates social memory and neural circuit formation in the developing brain by promoting synaptogenesis through SPARCL1.
Photocharge-Discharge Behaviors of Hybrid WO[sub 3]∕TiO[sub 2] Film Electrodes (2007)

Photoelectrochemical energy conversion and electron storage were investigated on hybrid film electrodes. Photoexcitation of was observed to undergo charge accumulation, i.e., double injection of electrons and protons into to form tungsten bronze by the oxidation of oxalic acid or methanol to form . It was clearly indicated that hybrid involving highly dispersed (an amorphous-like phase) exhibits more effective reversibility for photocharge-discharge processes than a hybrid involving a bulk polycrystalline . The energy band structure and phase changes of into tungsten bronze ( and ) by photocharge or electrocharge of the hybrid have also been characterized.
Selective IgA Deficiency in Charcot-Marie-Topth Disease (1979)

A selective IgA deficiency was found in five of 15 random patients with Charcot-Marie-Tooth disease. Immunologic studies of 32 members of the five families showed low IgA in 17 of the members, associated with elevated IgM in 20, without other significant immune abnormalities. The immunoglobulin pattern and the variability of symptoms in this familial peripheral neuropathy suggest that a thymic or gut-associated immune deficiency or both, may be causally related to the disease process.
Electron Beam - Directed Vapor Deposition of Low Cost Thermal Barrier Coatings (2000)

Abstract : The objective of this research is the development of improved performance, more affordable thermal barrier coatings via electron beam - directed vapor deposition (EB-DVD), a high efficiency vapor deposition technology developed and patented by the principle investigator and graduate student in University of Virginia's Intelligent Processing of Materials laboratory. During the research effort, experiments and modeling efforts were directed at development of coating structures with ultralow thermal conductivities. Yttria-stabilized zirconia layers with zig-zag morphologies and fine pore microstructures were produced with measured thermal conductivities of 0.8 W/mK. These coatings are of significant interest to industry engaged in production of naval aircraft and marine turbine engine applications, and specimens have been produced for their evaluation.
Mitochondrial Lysates Induce Inflammation and Alzheimer's Disease-Relevant Changes in Microglial and Neuronal Cells (2015)

Neuroinflammation occurs in Alzheimer's disease (AD). While AD genetic studies implicate inflammation-relevant genes and fibrillar amyloid-β protein promotes inflammation, our understanding of AD neuroinflammation nevertheless remains incomplete. In this study we hypothesized damage-associated molecular pattern (DAMP) molecules arising from mitochondria, intracellular organelles that resemble bacteria, could contribute to AD neuroinflammation. To preliminarily test this possibility, we exposed neuronal and microglial cell lines to enriched mitochondrial lysates. BV2 microglial cells treated with mitochondrial lysates showed decreased TREM2 mRNA, increased TNFα mRNA, increased MMP-8 mRNA, increased IL-8 mRNA, redistribution of NFκB to the nucleus, and increased p38 MAPK phosphorylation. SH-SY5Y neuronal cells treated with mitochondrial lysates showed increased TNFα mRNA, increased NFκB protein, decreased IκBα protein, increased AβPP mRNA, and increased AβPP protein. Enriched mitochondrial lysates from SH-SY5Y cells lacking detectable mitochondrial DNA (ρ0 cells) failed to induce any of these changes, while mtDNA obtained directly from mitochondria (but not PCR-amplified mtDNA) increased BV2 cell TNFα mRNA. These results indicate at least one mitochondrial-derived DAMP molecule, mtDNA, can induce inflammatory changes in microglial and neuronal cell lines. Our data are consistent with the hypothesis that a mitochondrial-derived DAMP molecule or molecules could contribute to AD neuroinflammation.
Electrolyzed Oxidizing Water for Cleaning-In-Place of Milking Systems on Dairy Farms - Performance Evaluation and Assessment (2012)

The cleanliness of on-farm milking systems directly affects the raw milk quality. A four-step procedure is the generally accepted method for cleaning-in-place (CIP) milking systems: (1) lukewarm water rinse, (2) alkaline cleaning, (3) acid rinse, and (4) sanitizer circulation. Electrolyzed oxidizing (EO) water is a novel technology in which acidic EO water and alkaline EO water are generated separately by electrolyzing diluted salt solution within an electrified chamber with a membrane to partition the alkaline and acidic EO waters. As these solutions fit perfectly with the basic requirements for CIP of milking systems, it was proposed that EO water can be used as a cleaning and sanitizing agent for CIP of milking systems. Previous studies in our lab showed that the utilization of EO water for CIP provided equal or better results than conventional cleaning on a pilot-scale milking system. The current project is undertaken to evaluate, assess, and validate this technology at a commercial dairy farm compared with conventional method of CIP. Results show that EO water CIP performance is as good as or better than conventional CIP for most of the sampling locations and system components. This indicates that EO water can be adapted as an alternative CIP method for dairy farms.
Fednets (2012)

A personal network (PN) is a network of a user’s personal devices and services, cooperating with each other independently of their geographical location to provide ubiquitous services to the user. PNs can be the producers and consumers of the services, content and resources. They can also export the subsets of their personal resources and services to other PNs. In such cases, PNs may form a group-oriented secure network called a Federation of Personal Networks (Fednet). A Fednet is a temporal, ad-hoc opportunity or purpose driven network of PNs, in which PNs collaborate with each other to share resources and services in a peer-to-peer manner. A Fednet is a pervasive and ubiquitous computing technology that enables the users to enjoy cooperation and promises exciting opportunities for different applications in various fields, such as education, healthcare, entertainment, business and emergency.In this chapter, the authors discuss PN technology expanding on the concept of Fednet. They provide example scenarios for Fednets, showing their potential impact to the quality of life of their users. Furthermore, they present the architecture and lifecycle of a Fednet. They explain the interactions of the main architectural components during its lifecycle and present a framework for the secure access control and management for a Fednet. The framework provides a controlled collaboration of PNs, where each PN controls the access to its resources and services. Finally, the authors provide a brief overview of some of the existing resource sharing group-oriented networks related to Fednets.

0088 Effect of different hydraulic squeeze chute and cattle breed on behavior of steer during restraining in feedyard facilities (2016)

The objective of this study was to investigate the relationship between hydraulic squeeze chute brand, breed of steers, and their behavior during processing in feedyard facilities. Two brands of hydraulic squeeze chute (A and B) and three breeds of cattle (Angus, Hereford and Continental cross) were compared. The assessments were made in 11 feedyards, totaling 1083 steers, using the BQA Feedyard Assessment (FA) guidelines for cattle handling in commercial feedlots. Each steer was observed once during and after the vaccination processing. Six feedyards had hydraulic squeeze chute (HSC) brand A (A) and eight feedyards had HSC brand B (B). The behavior variables of interest were vocalization, miscaught (MH), exit gait (run, trot or walk) and exit behavior (jump, stumble and fall). An effect of HSC brand on vocalization (P < 0.0001), exit gait (P < 0.0001) and exit behavior (P < 0.0001) was observed, but no effect on MH (P = 0.52) was observed. There was an effect of breed on vocalization (P < 0.0001), exit gait (P < 0.001) and exit behavior (P < 0.0001). The results for vocalization, run, trot, and jump were 25.8, 53.9, 40.4, and 14.4% for HSC A and 63.7, 42.5, 48.7, and 37.6% for HSC B, respectively. The results for vocalization, run, trot and jump were 15.1, 44.4, 47.5, and 29.4% for Angus; 2.7, 66.7, 28.8, and 17.8% for Hereford; and 22.2, 40.8, 50.7, and 31.8% for Continental cross, respectively. Brand of hydraulic squeeze chute and breed of cattle can influence the behavior of steers during and after restraining in feedyard facilities.
Load balancing from a Unix shell (2003)

A local area network of workstations often has a number of idle workstations that could be used to lower the load of active workstations. Widely used operating systems, such as Unix, often have the capability of remotely executing a program, but no automatic load balancing facilities. The authors report on a low-cost solution to workstation load redistribution by allowing the shell to select an alternate host for command execution.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">&gt;</ETX>
