Lamb Birth Weight is Affected by Culture System Utilized during in Vitro Pre-Elongation Development of Ovine Embryos (1995)

It has previously been reported that ovine embryos cultured in Synthetic Oviduct Fluid medium supplemented with 20% human serum (SOF+HS) develop into lambs with a high birth weight. We have investigated this phenomenon by culturing ovine zygotes in SOF+HS or a serum-free version of Synthetic Oviduct Fluid with BSA and amino acids (SOFaaBSA) in place of serum. Zygotes were either obtained from superovulated and naturally mated ewes or produced in vitro. Embryos were subsequently transferred to synchronized recipient ewes (n = 63). An additional group of ewes (n = 16) served as flock fertility and lambing controls. Development of zygotes to stages suitable for transfer (i.e., good to excellent compact morulae or blastocysts) was not affected by medium (SOFaaBSA = 53 +/- 5% vs. SOF+HS = 59 +/- 5%) but was affected by source (in vivo-derived = 74 +/- 5% vs. in vitro-derived = 35 +/- 5%, p < 0.001). Embryos incubated in SOF+HS were morphologically different from those incubated in SOFaaBSA, having abundant lipid droplets. Pregnancy rate (65%) and embryo survival (48%) of recipients determined by ultrasonography on approximately Day 60 of pregnancy did not differ between medium treatments or source of embryo. Mean weight of lambs from embryos cultured in SOF+HS (4.2 +/- 0.2 kg) was significantly heavier than that of controls (3.4 +/- 0.2 kg, p < 0.01) or of lambs from embryos cultured in SOFaaBSA (3.5 +/- 0.2 kg, p < 0.05). Furthermore, mean gestation length was longer in recipients receiving embryos incubated in SOF+HS (147 +/- 1 days) than in SOFaaBSA (145 +/- 1 day, p < 0.05). Reasons for this birth weight and gestation length difference are unclear, but our data suggest that different culture conditions can produce embryos with differing morphology, apparent chemical composition, and rate of development, resulting in lambs with differing gestation length and birth weight.
Synthesis and Characterization of a Family of Systematically Varied Tris(2-pyridyl)methoxymethane Ligands:  Copper(I) and Copper(II) Complexes (1998)

An efficient modular protocol for synthesizing a series of facial-capping tris-pyridyl ligands, based on the tris(2-pyridyl)methoxymethane backbone, has been developed which allows for systematic variations of the steric demands at the periphery of the ligand. The coordination chemistry of one such family of ligands that positions 0-->3 methoxy groups at the periphery with Cu(I) and Cu(II) is presented. The ligands are tris(2-pyridyl)methoxymethane (L(0)()), bis(2-pyridyl)(2-(6-methoxy)pyridyl)methoxymethane (L(1)()), bis(2-(6-methoxy)pyridyl)(2-pyridyl)methoxymethane (L(2)()), and tris(2-(6-methoxy)pyridyl)methoxymethane (L(3)()). The ligand exchange behavior and, to a lesser extent, the structures of the these complexes vary dramatically given the small perturbation of introducing methoxy substituents. Two distinct coordination modes are observed for the Cu(I) complexes, both in solution and the solid state. One is a pseudo-tetrahedral coordination comprised of the facial-capping, tris-pyridyl ligand and a monodentate ligand such as CH(3)CN, CO, or PPh(3). The other structural type is also a pseudo-tetrahedral Cu(I) monomer formed by two tris-pyridyl ligands coordinated in a bidentate manner with preferable binding by the nonmethoxy pyridyl subunits. With the exception of the most sterically hindered ligand, L(3)(), which only displays monoligation to Cu(I), all ligands form both types of Cu(I) complexes, and the formation is controlled by stoichiometry. Both competitive ligand binding experiments and ligand substitution with CO(g) show that the [(L(0)())(2)Cu](+) and [(L(1)())(2)Cu](+) complexes have nearly equivalent stability in aprotic solvent, and greater stability than the [(L(2)())(2)Cu](+) complex due to inclusion of bulky methoxypyridines into the Cu(I) coordination sphere. The Cu(II) complexes of the ligand series generate "bis-tris", [(L(0)()(-->)(3)())(2)Cu](2+), complexes, with the Cu(II) ligated in a tetragonally distorted octahedral coordination environment. The degree of bulk at the ligand periphery dictates the Cu(II)-ligand bond lengths both in solution and the solid state. In these complexes, the bulky pyridyl ring prefers to bind in the axial position. For the most sterically encumbered ligand, L(3)(), the bisligated Cu(II) complex is moisture sensitive, reacting to give a monoligated, tris-aqua species, [L(3)()Cu(H(2)O)(3)](2+).
Detection of sialomucin complex (MUC4) in human ocular surface epithelium and tear fluid. (2000)

Sialomucin complex was originally identified in rat mammary adenocarcinoma cells and has recently been shown to be produced by the ocular surface epithelia of rats. Furthermore, it has been identified as the rat homologue of human MUC4 mucin. The present studies show that it is expressed in the stratified epithelium covering the surface of the human eye and is present in human tear fluid. Expression of a carbohydrate-dependent epitope on the mucin subunit (ASGP-1) of sialomucin complex occurs in a differentiation-dependent fashion. Sialomucin complex joins MUC1 as another membrane mucin produced by the human ocular surface epithelia but is also found in the tear fluid, presumably in a soluble form, as found on the rat ocular surface.
Pitch-by-Pitch Extraction from Single View Baseball Video Sequences (2007)

This paper presents a novel method for reducing a baseball video segment from one batter to next batter into a more compact pitch-by-pitch video by pitching ball trajectory detection. The pitch-by-pitch video shows the complete pitching and batting process and largely reduces the source video data, making pitching analysis of broadcast baseball sequences an easier task. The proposed method has been tested for several long sequences, and promising results are reported.
A Review on Kombucha Tea—Microbiology, Composition, Fermentation, Beneficial Effects, Toxicity, and Tea Fungus (2014)

Fermentation of sugared tea with a symbiotic culture of acetic acid bacteria and yeast (tea fungus) yields kombucha tea which is consumed worldwide for its refreshing and beneficial properties on human health. Important progress has been made in the past decade concerning research findings on kombucha tea and reports claiming that drinking kombucha can prevent various types of cancer and cardiovascular diseases, promote liver functions, and stimulate the immune system. Considering the widespread reports on kombucha, we recognized the need to review and update the research conducted in relation to kombucha tea, its products and tea fungus. Existing reports have suggested that the protective effects of kombucha tea are as good as those of black tea, however, more studies on kombucha tea and its composition are needed before final conclusions can be made.

Distortion of a reduced equilibrium density matrix: Influence on quantum emulation (2016)

We study a system coupled to external degrees of freedom, called bath, where we assume that the total system consisting of system and bath is in equilibrium. An expansion in the coupling between system and bath leads to a general form of the reduced density matrix of the system as a function of the bath self energy. The coupling to the bath results in a renormalization of the energies of the system and in a change of the eigenbasis. This theory is applicable to quantum emulators in thermal equilibrium. Undesired external degrees of freedom can affect their reliability. We study the influence of bosonic degrees of freedom on the state of a six qubit system.
ZnCdSe/ZnCdMgSe quantum wells on InP substrates for visible emitters (1996)

We have grown ZnCdSe/ZnCdMgSe quantum well (QW) structures nearly lattice matched to InP substrates. Emission energies from 2.307 to 2.960 eV were measured by low-temperature photoluminescence at 10 K for samples with QW thicknesses between 5 and 80 Å. By using exactly lattice-matched QWs, the lower limit of the energy range can be lowered to about 2.2 eV (at 10 K). We propose that these structures could be used in entirely lattice-matched semiconductor lasers operating at room temperature in the blue, green, and yellow regions. Because of the absence of strain, these materials are expected to be less prone to degradation than the current blue-green lasers grown on GaAs.

Halogeno-complexes of cobalt(I) and nickel(I) with 1,1,1-tris(diphenylphosphinomethyl)ethane (1972)

The terdentate ligand 1,1,1-tris(diphenylphosphinomethyl)ethane (I) forms cobalt- and nickel-(I) complexes of general formula MLX (X = Cl, Br, or I). Spectral and magnetic data on the compounds are presented. They are non-electrolytes, are all isomorphous (X-rays) with the analogous Cu1 complexes, and probably have a pseudotetrahedral structure.
A feedback-based multimedia synchronization technique for distributed systems (1994)

Multimedia applications incorporate the use of more than one type of media, i.e., voice, video, data, text and image. With the advances in high-speed communication, the ability to transmit multimedia is becoming widely available. One of the means of transport for multimedia in distributed networks is Broadband Integrated Services Digital Network (B-ISDN). B-ISDN supports the transport of large volumes of data with a low error rate. It also handles the burstiness of multimedia traffic by providing dynamic bandwidth allocation. When multimedia is requested for transport in a distributed network, different Quality of Service (QOS) may be required for each type of media. For example, video can withstand more errors than voice. In order to provide, the most efficient form of transfer, different QOS media are sent using different channels. By using different channels for transport, jitter can impose skews on the temporal relations between the media. Jitter is caused by errors and buffering delays. Since B-ISDN uses Asynchronous Transfer Mode (ATM) as its transfer mode, the jitter that is incurred can be assumed to be bounded if traffic management principles such as admission control and resource reservation are employed.
Another network that can assume bounded buffering is the 16 Mbps token-ring LAN when the LAN Server (LS) Ultimedia$\sp{TM}$ software is applied over the OS/2 LAN Server$\sp{TM}$ (using OS/2$\sp{TM}$). LS Ultimedia$\sp{TM}$ reserves critical resources such as disk, server processor, and network resources for multimedia use. In addition, it also enforces admission control(1).
Since jitter is bounded on the networks chosen, buffers can be used to realign the temporal relations in the media. This dissertation presents a solution to this problem by proposing a Feedback-based Multimedia Synchronization Technique (FMST) to correct and compensate for the jitter that is incurred when media are received over high speed communication channels and played back in real time. FMST has been implemented at the session layer for the playback of the streams. A personal computer was used to perform their synchronized playback from a 16 Mbps token-ring and from a simulated B-ISDN network.
Stability of RNA Hairpins Closed by Wobble Base Pairs (1998)

Thermodynamic parameters are reported for hairpin formation in 1 M NaCl by RNA sequences of the type GGXANmAYCC, where XY is the wobble base pair, GU or UG, and the underlined loop sequences are three to eight nucleotides. A nearest-neighbor analysis indicates the free energy of loop formation is dependent upon loop size and closing base pair. Hairpin loops closed by UG base pairs are on average 1.3 kcal/mol less stable than hairpins closed by GU base pairs. The hairpin loops closed by UG have approximately the same stability as hairpin loops closed by AU/UA base pairs, while the loops closed by GU are approximately 0.7 kcal/mol more stable than hairpins loops closed by GC/CG base pairs. These results, combined with the model previously developed [Serra et al. (1997) Biochemistry 36, 4844] to predict the stability for hairpin loops closed by Watson-Crick base pairs, allow for the following model to predict the stability of hairpin loops: delta G degree 37L(n) = delta G degree 37iL(n) + delta G degree 37mm + 0.6 (if closed by AU, UA, or UB) - 0.7 (if closed by GU) - 0.7 (if first mismatch is GA or UU except for loops closed by GU). Here, delta G degree 37iL(n) is the free energy increment for initiating a loop of n nucleotides with a CG or GC pair, and delta G degree 37mm is the free energy for the interaction of the first mismatch with the closing base pair. For hairpin loops of n = 4-9, delta G037iL(n) is 4.9, 5.0, 5.0, 5.0, 4.9, and 5.5 kcal/mol, respectively. For hairpin loops of n = 3, delta G degree 37L(3) = +4.8 + 0.6 (if closed by AU, UA, or UG) kcal/mol. Thermodynamic parameters for hairpin formation in 1 M NaCl for 13 naturally occurring RNA hairpin sequences closed by wobble base pairs are reported. The model provides good agreement for both TM and delta G degree 37 for most hairpins studied. Thermodynamic values for five terminal mismatches adjacent to wobble base pairs are also reported.

Write Once, Run Anywhere A Survey of Mobile Runtime Environments (2008)

The hype surrounding Web 2.0 and technologies such as AJAX shows: The future of distributed application development lies in Rich Internet Applications (RIAs), which are based on highly distributed components and characterized by the intensive use of communication networks, complex interaction patterns and advanced GUI capabilities. As service providers begin to tap into the mobile market by extending the reach of their established e-commerce systems to mobile devices, a core challenge is the choice of a runtime environment and middleware that adapts well to the existing architecture, yet is a safe investment for the years to come. This paper surveys the current state and the future of runtime environments suitable for developing RIAs for mobile clients.
Interaction of the Vanadyl(IV) Cation with L-Ascorbic Acid and Related Systems (1998)

Abstract The interaction of VO 2+ with L-ascorbic acid and dehydroascorbic acid was investigated by electronic spectroscopy in solution at different pH values. In the case of ascorbic acid, two different solid complexes containing one or two monodeprotonated ascorbate ligands could be isolated and characterized. With dehydroascorbic acid, interaction begins at pH = 4 but at higher pH values the ligand is hydrolysed irreversibly, generating 2,3-diketogulonic acid. A solid complex containing this ligand could be precipitated at pH = 7. Its spectroscopic behavior confirms the interaction of the cation with an enolised form of the acid.
The maize duplicate genes <i>narrow sheath1</i> and <i>narrow sheath2</i> encode a conserved homeobox gene function in a lateral domain of shoot apical meristems (2004)

The narrow sheath (ns) phenotype of maize is a duplicate factor trait conferred by mutations at the unlinked loci ns1 and ns2. Recessive mutations at each locus together confer the phenotypic deletion of a lateral compartment in maize leaves and leaf homologs. Previous analyses revealed that the mediolateral axis of maize leaves is comprised of at least two distinct compartments, and suggest a model whereby NS function is required to recruit leaf founder cells from a lateral compartment of maize meristems. Genomic clones of two maize homeodomain-encoding genes were isolated by homology to the WUSCHEL-related gene PRESSED FLOWER (PRS). PRS is required for lateral sepal development in Arabidopsis, although no leaf phenotype is reported. Co-segregation of the ns phenotype with multiple mutant alleles of two maize PRS homologs confirms their allelism to ns1 and ns2. Analyses of NS protein accumulation verify that the ns-R mutations are null alleles. ns transcripts are detected in two lateral foci within maize meristems, and in the margins of lateral organ primordia. Whereas ns1 and ns2 transcripts accumulate to equivalent levels in shoot meristems of vegetative seedlings, ns2 transcripts predominate in female inflorescences. Previously undiscovered phenotypes in the pressed flower mutant support a model whereby the morphology of eudicot leaves and monocot grass leaves has evolved via the differential elaboration of upper versus lower leaf zones. A model implicating an evolutionarily conserved NS/PRS function during recruitment of organ founder cells from a lateral domain of plant meristems is discussed.

Video Flow Classification : Feature Based Classification Using the Tree-based Approach (2016)

This dissertation describes a study which aims to classify video flows from Internet network traffic. In this study, classification is done based on the characteristics of the flow, which includes features such as payload sizes and inter-arrival time. The purpose of this is to give an alternative to classifying flows based on the contents of their payload packets. Because of an increase of encrypted flows within Internet network traffic, this is a necessity. Data with known class is fed to a machine learning classifier such that a model can be created. This model can then be used for classification of new unknown data. For this study, two different classifiers are used, namely decision trees and random forest. Several tests are completed to attain the best possible models. The results of this dissertation shows that classification based on characteristics is possible and the random forest classifier in particular achieves good accuracies. However, the accuracy of classification of encrypted flows was not able to be tested within this project.
Detection of Anti-Hepatitis C Virus Effects of Interferon and Ribavirin by a Sensitive Replicon System (2005)

Although combination therapy with interferon and ribavirin has improved the treatment for chronic hepatitis C virus (HCV) infection, the detailed anti-HCV effect of ribavirin in clinical concentrations remains uncertain. To detect the anti-HCV effect of ribavirin in lower concentrations, a sensitive and accurate assay system was developed using the reporter replicon system with an HCV genotype 2a subgenomic replicon (clone JFH-1) that exhibits robust replication in various cell lines. This reporter replicon was generated by introducing the luciferase reporter gene (instead of the neomycin resistance gene) into the subgenomic JFH-1 replicon. To assess the replication of this reporter replicon, luciferase activity was measured serially up to day 3 after transient transfection of Huh7 cells. The luciferase activity increased exponentially over the time course of the experiment. After adjustment for transfection efficiency and transfected cell viability, the impacts of interferon and ribavirin were determined. The administration of interferon and ribavirin resulted in dose-dependent suppression of replicon RNA replications. The 50% inhibitory concentration of interferon and ribavirin was 1.80 IU/ml and 3.70 microg/ml, respectively. In clinical concentrations, replications were reduced to 0.09% and 53.74% by interferon (100 IU/ml) and ribavirin (3 microg/ml), respectively. Combination use of ribavirin and interferon enhanced the anti-HCV effect of interferon by 1.46- to 1.62-fold. In conclusion, we developed an accurate and sensitive replicon system, and the antivirus effect of interferon and ribavirin was easily detected within their clinical concentrations by this replicon system. This system will provide a powerful tool for screening new antiviral compounds against HCV.
