An extension of command shaping methods for controlling residual vibration using frequency sampling (2003)

The authors present an extension to the impulse shaping technique for commanding machines to move with reduced residual vibration. The extension, called frequency sampling, is a method for generating constraints that are used to obtain shaping sequences which minimize residual vibration in systems such as robots whose resonant frequencies change during motion. The authors present a review of impulse shaping methods, a development of the proposed extension, and a comparison of results of tests conducted on a simple model of the Space Shuttle robot arm. Frequency shaping provides a method for minimizing the impulse sequence duration required to give the desired insensitivity.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">></ETX>
Transient Dynamic Analysis of the Drillstring Under Jarring Operations by the FEM (1987)

Summary A drilling or a fishing jar is used in the bottomhole assembly (BHA) of a drillstring to free the string should it become stuck during the drilling operation. Because many expensive sensors are now incorporated in downhole tools, it is necessary to predict the damaging effect of jarring on these downhole sensors accurately. In addition, BHA's are becoming increasingly complex and are difficult to analyze by closed-form methods. For such reasons, the finite-element method (FEM) was used in this study to predict the dynamic response of a drillstring to jarring.
Micromechanical understanding of the cell-wall structure (2004)

For improving properties of pulp fibres, a better understanding of the relationships between its macroscopic mechanical properties, fibre ultrastructure, and properties of the wood polymers is important. This paper discusses such relations between elastic properties of fibres, their matrix structure and the wood polymer elastic constants. It is argued that an orientation of all of the wood polymers in the direction of the cellulose microfibrils is most likely. The elastic longitudinal modulus of cellulose is well described by the value of 134 GPa dominating the longitudinal fibre properties. In the transverse direction the amorphous polymers play a more important role.

History of Global Partners in Education (2011)

In the USA less than 4% of university students participate in Study Abroad programs (IIE Report). In most other parts of the world, the percentage is even smaller. There are many reasons for this with financial difficulty being the major factor. There are other contributing factors, such as fear of foreign settings, lack of knowledge in the foreign language, not accustomed to the local foods, fear of the risk of terrorism and infectious diseases, etc. However, while less than 4 % students can go abroad, 100% live in this same global world. All of us need to know about other cultures and understand the people from other cultures. While it is not possible to learn about all cultures, it is possible to acquire some basic knowledge about other countries. The knowledge of some different cultures will help us realize that all people do not think alike, do not have the same perspective, do not share the same values, and do not hold the same priorities. Thus when we are interacting with people from other cultures, we must try to interpret what happens in their part of the world using their lenses, and not our own. Global Partners in Education (GPE) is an organization that provides a global network of partner institutions to provide a cost effective and self-sustainable solution for students to interact with their peers around the world and to learn cultures from each other. This article is a short review of the background, the motivation, the process, and the success of GPE.
Performance of Hadoop Application on Hybrid Cloud (2015)

Hadoop is an open-source software framework for distributed computing that is widely used to develop large-scale data processing applications, such as big data applications. Hadoop application programs are normally run on in-house or cloud computing platforms. Recently, a hybrid cloud composed of in-house and remote cloud computing platforms has been found to be capable of sustaining a certain level of application performance. In this paper, we discuss the performance of a Hadoop application program running on such hybrid clouds. We will begin by presenting the performance model used to estimate the execution time of a Hadoop application program running on a hybrid cloud. Then, we will show the results of experiments conducted on hybrid cloud test beds. These experimental results revealed that the performance levels of the Hadoop application programs running on the hybrid cloud were application type dependent, and that performance improvements could be expected by using a remote cloud computing platform in conjunction with in-house computing platforms for certain types of applications. Furthermore, the results showed that our performance model captured the performance trend of the application programs on the hybrid cloud. However, room for improvement still exists in the performance model, particularly for the shuffle phase.
Molecular Characterization of the Multidrug Resistant Escherichia coli ST131 Clone (2015)

Escherichia coli ST131 is a recently emerged and globally disseminated multidrug resistant clone associated with urinary tract and bloodstream infections in both community and clinical settings. The most common group of ST131 strains are defined by resistance to fluoroquinolones and possession of the type 1 fimbriae fimH30 allele. Here we provide an update on our recent work describing the globally epidemiology of ST131. We review the phylogeny of ST131 based on whole genome sequence data and highlight the important role of recombination in the evolution of this clonal lineage. We also summarize our findings on the virulence of the ST131 reference strain EC958, and highlight the use of transposon directed insertion-site sequencing to define genes associated with serum resistance and essential features of its large antibiotic resistance plasmid pEC958.
Extracellular production of proteins by microorganisms. I. Screening for protein-producing bacteria. (1976)

Screening of protein-producing bacteria was conducted to systematically study the ubiquitous nature of the extracellular production of proteins and their excretion mechanisms. A very simple and efficient test revealed that about 15% of bacteria tested (total 1200 strains) accumulated some protein under the cultural conditions employed. Among protein-excretors, five strains produced a large amount of protein in the liquid shake culture. Many good protein producers including five excellent ones were found to be gram-positive rod and probably belong to Bacillus species. An acid-insoluble product by one of the hyperprotein producers was identified as a protein mixture. Good producer was not found among the known 15 species of bacteria. The implication of these findings is discussed.
Structural quality and the growth mode in epitaxial ZnSe/GaAs(100) (1993)

We have investigated the effect of the initial growth mode on the structural quality and dislocation configuration in epitaxial ZnSe/GaAs(100). We find that a three-dimensional initial growth mode strongly degrades the crystal quality and results in a high density of threading dislocations and short misfit dislocation segments. On the other hand a two-dimensional growth mode, achieved by a Zn exposure treatment of GaAs surfaces, results in few threading dislocations and long misfit dislocations. These differences are explained by postulation of new dislocation generation sites created by island coalescence.

Sulfation of chondroitin sulfate proteoglycans is necessary for proper Indian hedgehog signaling in the developing growth plate (2009)

In contrast to the functional role of heparan sulfate proteoglycans (HSPGs), the importance of chondroitin sulfate proteoglycans (CSPGs) in modulating signaling pathways involving hedgehog proteins, wingless-related proteins and fibroblast growth factors remains unclear. To elucidate the importance of sulfated CSPGs in signaling paradigms required for endochondral bone formation, the brachymorphic (bm) mouse was used as a model for undersulfated CSPGs. The bm mouse exhibits a postnatal chondrodysplasia caused by a mutation in the phosphoadenosine phosphosulfate (PAPS) synthetase (Papss2) gene, leading to reduced levels of PAPS and undersulfated proteoglycans. Biochemical analysis of the glycosaminoglycan (GAG) content in bm cartilage via sulfate labeling and fluorophore-assisted carbohydrate electrophoresis revealed preferential undersulfation of chondroitin chains (CS) and normal sulfation of heparan sulfate chains. In situ hybridization and immunohistochemical analysis of bm limb growth plates showed diminished Indian hedgehog (Ihh) signaling and abnormal Ihh protein distribution in the extracellular matrix. Consistent with the decrease in hedgehog signaling, BrdU incorporation exhibited a significant reduction in chondrocyte proliferation. Direct measurements of Ihh binding to defined GAG chains demonstrated that Ihh interacts with CS, particularly chondroitin-4-sulfate. Furthermore, co-immunoprecipitation experiments showed that Ihh binds to the major cartilage CSPG aggrecan via its CS chains. Overall, this study demonstrates an important function for CSPGs in modulating Ihh signaling in the developing growth plate, and highlights the importance of carbohydrate sulfation in regulating growth factor signaling.
Visual search using artificial intelligence (2019)

With the development of mobile device, the process of image usage is trending more and more popular. People use their phone for taking photo to save the treasury memories. With the rising of Socio-culture which people share their photos into the social media for daily basis. Photos are become more and more informative to the owner of photo in terms of the content ,location and time that photo was taken. Therefore, the idea of a photo gallery system is purposed. The focus of the photo gallery system is to remove the duplicated images and generate the image information. The project assigned was Visual Search Using deep learning. Specifically, this project aims to explore possible applications using deep learning techniques to build up a system combine with image cluster and image captioning application. This project will focus on finding the best model for image captioning and image clustering. Image processing and natural language processing will be used for both applications. A performance analysis will be followed with the result from several models to select the best model for both of applications. The performance metrices for each application will based on the popular benchmark’s metrics.

Immunization against Pseudomonas in Infection after Thermal Injury (1974)

Three hundred twenty-two patients with injuries involving burns over 20% of their total body surface areas have been actively immunized with a polyvalent vaccine against Pseudomonas aeruginosa at the University of Cincinnati Burn and Trauma Unit and the Cincinnati Shriners Burns Institute during the five-year period preceding April 1973. Of a similar group of 75 consecutive unvaccinated controls treated between March 1967 and April 1968, 14.7% died from pseudomonas infection, and 18.7% died from pseudomonas bacteremia. With an increase in dose and in duration of vaccination, the incidence of pseudomonas bacteremia declined to 6%. Of 96 patients who were immunized with the maximal dose, 3.1% died, but none of the last 186 vaccinated pateints, for whom hyperimmune γ-globulin to Pseudomonas was used as adjunctive treatment of pseudomonas bacteremia, has died. These clinical observations have been accompanied by a variety of immunologic studies, which confirmed that immunization with the polyvalent vaccine induced production of an immune IgG antibody. Invasive infection with P. aeruginosa is accompanied or preceded by a variety of immunologic deficiencies that can be compensated for by the administration of immune IgG antibody. Predominant among these deficiencies are abnormalites of the alternate pathway of complement and of the antibacterial function of neutrophils. Our results strongly suggest that patients with major thermal injuries should be actively vaccinated against Pseudomonas, and that hyperimmune γ-globulin to Pseudomonas is an effective adjunctive measure for the treatment of life-threatening infections caused by P. aeruginosa.
Radiometric assay of bacterial growth: analysis of factors determining system performance and optimization of assay technique. (1987)

A quantitative technique for the measurement of 14CO2 released from a bacterial culture was evaluated. The technique uses liquid scintillation counting to record 14CO2 accumulation on a fluor-impregnated filter paper within a double-chambered scintillation vial that also houses the bacterial growth medium. We have successfully identified and corrected the major causes for a variably low detection efficiency, and also established the optimum mixture of reagents for the detection system. Incorporation of Triton X-100 into the scintillation fluid used for the detector reduced the variability between identical assays in a single batch from 50% to 5%, and, in conjunction with an increase in the scintillator concentration, raised the counting efficiency from 30% to 70-88%. The response of the improved detector is linear over a wide range of count-rates. Another significant modification was the interchange of growth and detector chambers. Overall, a 40-fold increase in count-rate during the exponential phase of bacterial growth was obtained by improving 14CO2 detection efficiency, increasing the rate of 14CO2 transfer from liquid to gas phases and enlarging the growth supporting capacity of the detector system. The minimum detection time for bacterial growth was shortened and the exponential phase of bacterial proliferation was lengthened by at least 2 hr. High counting efficiency, precision, and linearity make the improved detector a sensitive and reliable tool for radiometry of bacterial growth and metabolism.
On attempts at solvolytic generation of aryl cations (1976)

The solvolysis of phenyl triflate (3), phenyl nonaflate (4), o-methylphenyl nonaflate (5), o-cyclopropylphenyl nonaflate (6), o-methoxyphenyl triflate (7), 2,6-dimethoxyphenyl triflate (S), 2,6-diisopropylphenyl triflate (9), 33- dimethoxyphenyl triflate (lo), 3,5-dicyclopropylphenyl triflate (11), 3,5-di(2-methylcyclopropyl)phenyl triflate (12), 2,4,6-tricyclopropylphenyltr iflate (13), and 2,4,6-triisopropylphenytlr iflate (14) were examined in great detail under a wide variety of conditions. In highly polar nonnucleophilic solvents no reaction was observed and the unreacted triflates were recovered quantitatively. In the presence of nucleophiles or nucleophilic solvents the sole products observed were the corresponding phenols. Careful labeling and product studies showed that these phenols arose by nucleophilic attack on sulfur and S-0 bond cleavage. We have not been able to find any evidence for aryl cation intermediates.
A patient with primary biliary cirrhosis and ulcerative colitis with progression to primary sclerosing cholangitis and colorectal cancer: A case report (2013)

Introduction: Ulcerative colitis (UC) is a chronic inflammatory disease of the colon characterized by intermittent exacerbations and remissions. It can be associated with primary biliary cirrhosis (PBC) or primary sclerosing cholangitis (PSC) and complicated with colorectal cancer (CRC). We describe a complicated case of associaton of PBC and chronic UC, eventually progressed to PSC and CRC. Case report: A 41­year­old female was diagnosed as PBC based on liver biopsy 10 years ago, and then UC was diagnosed too. Now symptoms of jaundice and abdominal pain aggravated. At last PSC and CRC were conformed. Conclusion: Prolonged Inflammatory bowel disease (IBD) accompanied with PSC in a patient has high risk of CRC. More exploration is needed to gain insight into relationship between IBD, PBD, PSC and CRC.
Sound Pressure Measurement Equipment for the Range 50 Cycles to 250 kc (1948)

This paper describes a newly developed acoustic instrument that is now commerically available for making absolute sound pressure measurements over the frequency range 50 cycles to 250 kc. The microphone standard is only 18″ diameter, and is therefore completely free of diffraction errors throughout the entire audible spectrum to beyond 20 kc. In order to maintain constant phase shift between the generated voltage and the actuating pressure, the vibrating system is stiffness controlled to beyond 250 kc, thus insuring accurate reproduction of pressure wave transients having extremely steep wave fronts. The tiny size of the microphone and its very high acoustic impedance will permit free field measurements throughout the entire audible range without diffraction errors, as well as making easily possible many special acoustic measurements extending well into the ultrasonic region, heretofore very difficult to make. One such application now in progress is the analysis of the sound spectrum from jet engines up to frequencies of 250 kc. A preamplifier and power supply unit makes the equipment readily portable.
Energy-scaling characteristics of solitons in strongly dispersion-managed fibers (1996)

We present an empirical scaling law that models the increased energy required for launching a soliton into an optical system with sections of both normal and anomalous dispersion fiber. It is shown that the inclusion of periodic attenuation and amplification can be handled as separate problems, provided that the interval between optical amplifiers is substantially different from the period of the dispersion map. These concepts are illustrated by reference to an example system comprising dispersion-shifted fiber combined with anomalous standard fiber.

Generation of second harmonic radiation from sub-stoichiometric silicon nitride thin films (2013)

Enhancing second-order optical processes in Si-compatible materials is important for the demonstration of innovative functionalities and nonlinear optical devices integrated on a chip. Here, we demonstrate significantly enhanced Second-Harmonic Generation (SHG) by silicon-rich silicon nitride materials over a broad spectral range, and show a maximum conversion efficiency of 4.5 × 10−6 for sub-stoichiometric samples with 46 at. % silicon. The SHG process in silicon nitride thin films is systematically investigated over a range of material stoichiometry and thermal annealing conditions. These findings can enable the engineering of innovative Si-based devices for nonlinear signal processing and sensing applications on a Si platform.
