ROLE OF MARINE FUNGI IN THE BIOCHEMISTRY OF THE OCEANS IV (1964)

Sguros, Peter L. (University of Miami, Miami, Fla.), and Jacqueline Simms. Role of marine fungi in the biochemistry of the oceans. IV. Growth responses to seawater inorganic macroconstituents. J. Bacteriol. 88:346-355. 1964.-The filamentous ascomycete Halosphaeria mediosetigera and the deuteromycete Culcitalna achraspora were gravimetrically characterized by growth curves in natural and artificial seawater media. Response to growth media employing these diluents was very similar, and stationary phases of both cultures showed autolysis. The organisms grew at all concentrations of seawater, but growth maxima were observed between 20 and 60%. Neither seawater was able to reduce the requirement for yeast extract. Glass-distilled water was slightly better than artificial seawater for the survival of homogenized, washed, resting mycelia over long periods at 4 C. Regardless of suspending medium, this treatment did not appreciably alter the regenerative vigor of inocula. Qualitative and quantitative variations of artificial seawater, without rigid exclusion of inorganic traces from experimental media, demonstrated separate growth requirements for Na, K, Mg, Ca, and SO(4). Only K and Ca appeared nontoxic at seawater concentrations, however. Some evidence of Na antagonism by Mg was obtained. Responses to test ions were best observed in the absence of seawater amounts of NaCl. Reactions of these generically distinct fungi to most experimental manipulations were markedly alike. Both fungi appeared to be appropriately labeled "marine," judging by criteria currently in general use.

A Study of Liquid Dispensing Head Using Fluidic Inertia (2002)

A nanoliter dispensing head based on a novel principle has been proposed. In this dispensing head, a piezo ceramics transducer moves a glass capillary holding liquid in the direction of dispensation. As a result of this movement, pressure waves are generated in the capillary, resulting in the dispensing of a small droplet from the nozzle. In order to understand the basic performance of this head, we have studied the effect of voltage waveform application to the piezo ceramics transducer on droplet formation. We have also studied the effect of sample liquid volume in the capillary on droplet formation and the effect of sample liquid viscosity on droplet properties. Under typical dispensing conditions, the volume of a drop was 1 nl and the coefficient of variation was 5%.
Zebrafish myelination: a transparent model for remyelination? (2008)

There is currently an unmet need for a therapy that promotes the regenerative process of remyelination in central nervous system diseases, notably multiple sclerosis (MS). A high-throughput model is, therefore, required to screen potential therapeutic drugs and to refine genomic and proteomic data from MS lesions. Here, we review the value of the zebrafish (Danio rerio) larva as a model of the developmental process of myelination, describing the powerful applications of zebrafish for genetic manipulation and genetic screens, as well as some of the exciting imaging capabilities of this model. Finally, we discuss how a model of zebrafish myelination can be used as a high-throughput screening model to predict the effect of compounds on remyelination. We conclude that zebrafish provide a highly versatile myelination model. As more complex transgenic zebrafish lines are developed, it might soon be possible to visualise myelination, or even remyelination, in real time. However, experimental outputs must be designed carefully for such visual and temporal techniques.
Online Monitoring of Corrosion under Cathodic Protection Conditions Utilizing Coupled Multielectrode Sensors (2004)

Abstract Real-time corrosion monitoring for carbon steel materials in simulated seawater under cathodic protection conditions was conducted, utilizing coupled multielectrode sensors. It was demonstrated that the coupled multielectrode sensor is an effective real-time tool for monitoring the effectiveness of cathodic protection and for measurement of the threshold value of the protection potential for specific equipment.
Dual Control of Phenyladanine Ammonia‐Lyase Production and Removal by Its Product Cinnamic Acid (1982)

l ‐Phenylalanine ammonia‐lyase (EC 4.3.1.9, which catalyses the first reaction in the biosynthesis of plant phenylpropanoid products, undergoes a transient increase in activity in excised sections of pea ( Pisum sativum ) epicotyl tissue. Exogenous supplies of pathway intermediates inhibit the initial development of phenylalanine ammonia‐lyase activity and, if added at the time of high enzyme levels, cause a rapid decay in enzyme activity. The inhibitory effect of exogenous cinnamic acid, the immediate product of the enzyme, is expressed very rapidly (lag < 1 h) with the initial rate of decay of enzyme activity and the final steady‐state level of enzyme activity being dependent on the concentration of cinnamic acid. The response has been studied by density labelling in vivo with 2 H from 2 H 2 O with analysis of the equilibrium distribution of enzyme activity in high‐resolution KBr density gradients. Cinnamic acid, at a concentration of 1 mM completely inhibits further incorporation of label and also markedly stimulates the removal of pre‐existing, unlabelled enzyme. Inhibition of de novo production and stimulation of removal occur at concentrations of cinnarnic acid as low as 10 μM. The initial increase in enzyme activity reflects an increase in the rate of de novo enzyme production against a low background rate of enz:yme removal. The subsequent decay in enzyme activity is a result of a decline in production of the enzyme concomitant with a marked increase in the rate of removal of enzyme activity. In the presence of α‐ aminooxy‐β‐phenylpropionic acid, which specifically inhibits phenylalanine ammonia‐lyase and hence endogenous generation of cinnamic cid, high rates of enzyme production and low rates of enzyme removal are maintained leading to high levels of zyme activity in the later stages of enzyme induction. These data indicate the operation of dual feedback modulation of phenylalanine ammonia‐lyase in vivo following endogenous production of cinnamic acid. Such dual control by a product over both production and removal of an enzyme may be of general importance in slowly growing plant cells for the rapid removal of biosynthetic enzymes no longer required by the cell.

Investigations of Hydrogen Implanted GaP Single Crystals by Means of Particle Induced γ-Spectroseopy, Infrared Spectroscopy, and Rutherford Backscattering Channelling Technique (1985)

The incorporation of hydrogen into GaP single crystals bombarded with 0.3 and 1.0 MeV protons it investigated in the fluence range to 1018 cm−2. The combination of infrared spectroscopy and trarticle induced γ-spectroscopy with the Rutherford backscattering channelling technique enables to study hydrogen incorporation, hydrogen trapping, and lattice damage and to determine the satio of the chemically bonded to the total incorporated amount of hydrogen dependent on the defect profile. The use of the ion beam etching technique allows the investigation of depth profiles within larger depth regions. Die Einlagerung von Wasserstoff in mit 0,3- und 1,0 MeV-Protonen beschossenen GaP-Einkristallen wird im Dosisbereich bis 1018 cm−2 untersucht. Durch die Kombination von Infrarotspek-troskopie und teilcheninduzierter γ-Spektroskopie mit der Rutherford-Rückstreu-Kanalisierungs-technik gelingt es, Aussagen zu treffen über die Wasserstoffeinlagerung, die Wasserstoffanlagerung, die Strahlenschadigung und das Verhältnis von chemisch gebunden zu ungebunden enthaltenem Wasserstoff. Der Einsatz der Schrägschlifftechnik gestattet die Aufnahme von Wasserstoffkonzentrationsprofilen bis in größere Tiefenbereiche.

Travel Ontology for Recommendation System based on Semantic Web (2006)

This paper presents the Travel Ontology to retrieve information from Recommendation System based on Semantic Web. The Metadata is made by preference profile and transaction profile. Information Repository is consisting of Travel Information and Ontology. The Travel Ontology is made by OWL, rule based on Description Logic. The top class is Travel as the domain to build the Travel Ontology. And Accommodation, Activity, Food and Transportation are selected as the upper class. The subclass of the Activities consists of LeisureSports and TourismCulture. At last, the result of Recommendation following scenario using OWL-QL is shown. We propose the Travel Recommendation System in Semantic Web using Ontology. As you know, we can easily insert attributes to Ontology. Besides we can inference from rules and properties in ontology.
Atrial fibrillation signatures on intracardiac electrograms identified by deep learning (2022)

Deep learning of intracardiac EGMs can identify AF or AT via signatures of rate, regularity in timing or shape, and specific EGM shapes. Future work should examine if these signatures differ between different clinical subpopulations with AF.
<title>Iterative Method Applied To Image Reconstruction And To Computer-Generated Holograms</title> (1979)

This paper discusses an iterative computer method that can be used to solve a number of problems in optics. This method can be applied to two types of problems: (1) synthesis of a Fourier transform pair having desirable properties in both domains, and (2) reconstruction of an object when only partial information is available in any one domain. Illustrating the first type of problem, the method is applied to spectrum shaping for computer-generated holograms to reduce quantization noise. A problem of the second type is the reconstruction of astronomical objects from stellar speckle interferometer data. The solution of the latter problem will allow a great increase in resolution over what is ordinarily obtainable through a large telescope limited by atmospheric turbulence. Experimental results are shown. Other applications are mentioned briefly.
Corrections to "Avoiding packaging mismatch with flexible packaging" (2001)

To integrate a software component into a system, it must interact properly with the system’s other components. Unfortunately, the decisions about how a component is to interact with other components are typically committed long before the moment of integration and are difficult to change. This paper introduces the Flexible Packaging method, which allows a component developer to defer some decisions about component interaction until system integration time. The method divides the component’s source into two pieces: the ware, which encapsulates the component’s functionality; and the packager, which encapsulates the details of interaction. Both the ware and the packager are independently reusable. A ware, as a reusable part, allows a given piece of functionality to be employed in systems in different architectural styles. A packager, as a reusable part, encapsulates conformance to a component standard, like an ActiveX control or an odbc database accessor. Because the packager’s source code is often formulaic, a tool is provided to generate the packager’s source from a highlevel description of the intended interaction, a description written in the architectural description language UniCon. The method and tools are evaluated with two case studies, an image viewer and a database updater.
Framework for MPLS-based control of optical SDH/SONET networks (2001)

The suite of protocols that defines multiprotocol label switching is in the process of enhancement to generalize its applicability to the control of optical networks. One area of prime consideration is to use these generalized MPLS protocols in upgrading the control plane of optical transport networks. This article describes those extensions to MPLS directed toward controlling SDH/SONET networks. SDH/SONET networks are ideal candidates for this process since they possess a rich multiplex structure, and a variety of protection/restoration options are well defined and widely deployed. We discuss the extensions to MPLS routing protocols to disseminate information needed for transport path computation and network operations and the extensions to MPLS label distribution protocols needed for provisioning of transport circuits.
The Effect of Urea on Tobacco Mosaic Virus: Polarity of Disassembly (1982)

SUMMARY Urea acts to disassemble tobacco mosaic virus (TMV) predominantly from the 5'-end of the virus RNA. Extensively uncoated particles exhibit some degree of bi-directional uncoating as judged by a reduced ability to bind [3H]histidine. The translational activities of the RNA fragments which remained encapsidated in the urea-resistant fraction of TMV rods were investigated.
Functional Analysis of the RING-Type Ubiquitin Ligase Family of Arabidopsi<i>s</i>    (2005)

Approximately 5% of the Arabidopsis (Arabidopsis thaliana) proteome is predicted to be involved in the ubiquitination/26S proteasome pathway. The majority of these predicted proteins have identity to conserved domains found in E3 ligases, of which there are multiple types. The RING-type E3 is characterized by the presence of a cysteine-rich domain that coordinates two zinc atoms. Database searches followed by extensive manual curation identified 469 predicted Arabidopsis RING domain-containing proteins. In addition to the two canonical RING types (C3H2C3 or C3HC4), additional types of modified RING domains, named RING-v, RING-D, RING-S/T, RING-G, and RING-C2, were identified. The modified RINGs differ in either the spacing between metal ligands or have substitutions at one or more of the metal ligand positions. The majority of the canonical and modified RING domain-containing proteins analyzed were active in in vitro ubiquitination assays, catalyzing polyubiquitination with the E2 AtUBC8. To help identity regions of the proteins that may interact with substrates, domain analyses of the amino acids outside the RING domain classified RING proteins into 30 different groups. Several characterized protein-protein interaction domains were identified, as well as additional conserved domains not described previously. The two largest classes of RING proteins contain either no identifiable domain or a transmembrane domain. The presence of such a large and diverse number of RING domain-containing proteins that function as ubiquitin E3 ligases suggests that target-specific proteolysis by these E3 ligases is a complex and important part of cellular regulation in Arabidopsis.

To assess fission-fragment damage as flux-pinning centers, sintered compacts of ${\mathrm{YBa}}_{2}$${\mathrm{Cu}}_{3}$${\mathrm{O}}_{7}$ were prepared with uranium additions of 150 and 380 atomic ppm and exposed to thermal neutron fluences of 4.3\ifmmode\times\else\texttimes\fi{}${10}^{17}$, 1.2\ifmmode\times\else\texttimes\fi{}${10}^{18}$, and 4.0\ifmmode\times\else\texttimes\fi{}${10}^{18}$/${\mathrm{cm}}^{2}$. Magnetic hysteresis measurements were made as functions of temperature at fields up to 2.5 T. The hysteresis at 1 T for the sample containing 150 ppm uranium increased upon an irradiation of 1.2\ifmmode\times\else\texttimes\fi{}${10}^{18}$/${\mathrm{cm}}^{2}$ by 3.7 times at 4.5 K, 20 times at 63 K, and 8.3 times at 77 K. Much smaller increases in magnetic hysteresis were observed in undoped samples exposed to thermal neutrons. Critical-current densities were calculated from the hysteresis observed at 1 T using the critical-state model, assuming the currents to be restricted to the grains (\ensuremath{\approxeq}5 \ensuremath{\mu}m radius). For the 150 ppm, 1.2\ifmmode\times\else\texttimes\fi{}${10}^{18}$/${\mathrm{cm}}^{2}$ sample, the 1-T intragranular critical-current densities obtained are 1.5\ifmmode\times\else\texttimes\fi{}${10}^{7}$, 1.0\ifmmode\times\else\texttimes\fi{}${10}^{6}$, and 1.4\ifmmode\times\else\texttimes\fi{}${10}^{5}$ A/${\mathrm{cm}}^{2}$ at temperatures of 4.5, 63, and 77 K, respectively. The critical temperatures by an ac susceptibility technique showed that the 4\ifmmode\times\else\texttimes\fi{}${10}^{18}$/${\mathrm{cm}}^{2}$ irradiation lowered the onset critical temperatures only slightly, from 91 to 90 K and from 91.5 to 89 K for the 150 and 380 ppm samples, respectively.
Experimental Study of Sound-Wave Phase Fluctuations Caused by Turbulent Wakes (1970)

Ultrasonic waves were sent through the wakes of circular cylinders of certain simple profiles and of plates in air flow. By application of multichannel pulse-height analysis, probability density distributions of the sound-wave phase fluctuations (“phase spectra”) were measured. One gets Gaussian distributions in cases of purely turbulent flow and characteristically shaped curves (most often with two maxima), if, additionally, the wake flow contains discrete vortices. The computer-aided evaluation of the phase spectra allows, simultaneously, determination of the magnitude of the turbulent motion in direction of the sound-wave propagation and the circulation of the vortices and, furthermore, leads to information about the general structure of the flow.
