The Structure of Aluminosilicate Glasses:  High-Resolution <sup>17</sup>O and <sup>27</sup>Al MAS and 3QMAS NMR Study (2000)

We investigate short-range order and local atomic configuration in charge-balanced aluminosilicate glasses as functions of composition, using 17O and 27Al MAS and triple-quantum magic angle spinning (3QMAS) NMR spectroscopy. Enhanced resolution in 17O and 27Al 3QMAS spectra, compared to MAS NMR, allows the quantification of the spectra and the extent of disorder using a semiempirical function relating 3QMAS efficiency to a quadrupolar coupling constant (Cq). The variations with the Si/Al ratio (R) in peak positions and widths in the isotropic dimension of 27Al 3QMAS NMR spectra in both Na- and Ca-aluminosilicate glasses can be ascribed to variations in the populations of Al sites with varying numbers of Al vs Si neighbors with composition. In the 17O 3QMAS spectra, variations of populations of three clearly resolved oxygen sites (Al−O−Al, Si−O−Al, and Si−O−Si) with R and cation field strength are consistent with the predictions given in our previous results from 29Si MAS NMR. The quadrupolar coupling product (Pq) of each oxygen site does not vary significantly with R, but it increases with cation field strength. On the other hand, isotropic chemical shifts ( ) increase with decreasing R and increasing cation field strength. These trends suggest that the configuration and framework connectivity in aluminosilicate glasses and melts are relatively constant with R but can be perturbed by high field strength cations with increased Al−O−Al and angular disorder, manifested by the increased variation of and the formation of non-bridging oxygen (NBO). The extent of disorder in aluminosilicate glasses is reflected in calculated configurational enthalpy, which increases with increasing cation field strength, consistent with the excess enthalpy of mixing data from calorimetry. The method and results given here provide improved prospects for the quantitative application of 3QMAS NMR and add to a more complete understanding of framework site connectivity in aluminosilicate glasses.

Open Reduction and Internal Fixation Compared with Circular Fixator Application for Bicondylar Tibial Plateau Fractures (2009)

Both techniques provide a satisfactory quality of fracture reduction. Because percutaneous reduction and application of a circular fixator results in a shorter hospital stay, a marginally faster return of function, and similar clinical outcomes and because the number and severity of complications is much higher with open reduction and internal fixation, we believe that circular external fixation is an attractive option for these difficult-to-treat fractures. Regardless of treatment method, patients with this injury have substantial residual limb-specific and general health deficits at two years of follow-up.

Spectral velocity analysis for the determination of ground‐wave velocities and their uncertainties in multi‐offset GPR data (2012)

ABSTRACT In many hydrological applications, ground‐wave velocity measurements are increasingly used to map and monitor shallow soil water content. In this study, we propose an automated spectral velocity analysis method to determine the direct ground‐wave (DGW) velocity from common midpoint (CMP) or multi‐offset ground‐penetrating radar (GPR) data. The method introduced in this paper is a variation of the well‐known spectral velocity analysis for seismic and GPR reflection events where velocity spectra are computed using different coherency measures along hyperbolas following the normal moveout model. Here, the unnormalized cross‐correlation is computed between waveforms across data gathers that are corrected with a linear moveout equation using a predefined range of velocities. Peaks in the resulting velocity spectra identify linear events in the GPR data gathers like DGW events and allow for estimating the corresponding velocities. In addition to obtaining a DGW velocity measurement, we propose a robust method to estimate the associated velocity uncertainties based on the width of the peak in the calculated velocity spectrum. Our proposed method is tested on synthetic data examples to evaluate the influence of subsurface velocity, surveying geometry and signal frequency on the accuracy of estimated ground‐wave velocities. In addition, we investigate the influence of such velocity uncertainties on subsequent soil water content estimates using an established petrophysical relationship. Furthermore, we apply our approach to analyse field data, which were collected across a test site in Canada to monitor a wide range of seasonal soil moisture variations. A comparison between our spectral velocity estimates and results derived from manually picked ground‐wave arrivals shows good agreement, which illustrates that our spectral velocity analysis is a feasible tool to analyse DGW arrivals in multi‐offset GPR data gathers in an objective and more automated manner.
Purification and Characterization of 17β-Hydroxysteroid Dehydrogenase from Cylindrocarpon radicicola1 (1988)

An NAD+-linked 17 beta-hydroxysteroid dehydrogenase was purified to homogeneity from a fungus, Cylindrocarpon radicicola ATCC 11011 by ion exchange, gel filtration, and hydrophobic chromatographies. The purified preparation of the dehydrogenase showed an apparent molecular weight of 58,600 by gel filtration and polyacrylamide gel electrophoresis. SDS-gel electrophoresis gave Mr = 26,000 for the identical subunits of the protein. The amino-terminal residue of the enzyme protein was determined to be glycine. The enzyme catalyzed the oxidation of 17 beta-hydroxysteroids to the ketosteroids with the reduction of NAD+, which was a specific hydrogen acceptor, and also catalyzed the reduction of 17-ketosteroids with the consumption of NADH. The optimum pH of the dehydrogenase reaction was 10 and that of the reductase reaction was 7.0. The enzyme had a high specific activity for the oxidation of testosterone (Vmax = 85 mumol/min/mg; Km for the steroid = 9.5 microM; Km for NAD+ = 198 microM at pH 10.0) and for the reduction of androstenedione (Vmax = 1.8 mumol/min/mg; Km for the steroid = 24 microM; Km for NADH = 6.8 microM at pH 7.0). In the purified enzyme preparation, no activity of 3 alpha-hydroxysteroid dehydrogenase, 3 beta-hydroxysteroid dehydrogenase, delta 5-3-ketosteroid-4,5-isomerase, or steroid ring A-delta-dehydrogenase was detected. Among several steroids tested, only 17 beta-hydroxysteroids such as testosterone, estradiol-17 beta, and 11 beta-hydroxytestosterone, were oxidized, indicating that the enzyme has a high specificity for the substrate steroid. The stereospecificity of hydrogen transfer by the enzyme in dehydrogenation was examined with [17 alpha-3H]testosterone.
Yield Differences between Research Plots and Managed Forests (1977)

Abstract Differences between timber yields on small research plots and on managed forests are due mainly to differences in definition of forested area, in scale and quality control of management treatments, and in uniformity of the stands. In large areas where management has not yet made stands uniform, research results may serve only as general guides to potential growth. The manager who is practicing some degree of intensive forestry can often find research data on which to base accurate estimates of growth and yield. To apply the information, he must exclude unproductive areas from estimates of his acreage, monitor stands for damage, and supervise treatments efficiently. There is, however, no single magic number that adjust for differences in growth between research plots and larger managed forests.
A new WDM random access control protocol in LAN (2002)

The lightwave network is introduced to exploit the huge optical bandwidth with concurrency among multiple-user transmissions in the network architectures and protocols. Receiver collision is a common problem in a single-hop WDM network with random access control protocols. This paper proposes an RRC protocol (reduced receiver collision) with waiting-queue and channel-usage table. It has been shown from analysis and simulation that the RRC protocol has a much lower delay and a higher throughput than the ISA (improved slotted ALOHA) protocol. Therefore, it is a good medium access control protocol for use in LAN.
Distributed and Decentralized Voltage Control of Smart Distribution Networks: Models, Methods, and Future Research (2017)

The future grid is evolving into a smart distribution network that integrates multiple distributed energy resources ensuring at the same time reliable operation and increased power quality. In recent years, many research papers have addressed the voltage violation problems that arise from the high penetration of distributed generation. In view of the transition to active network management and the increase in the quantity of collected data, distributed control schemes have been proposed that use pervasive communications to deal with the complexity of smart grid. This paper reviews the recent publications on distributed and decentralized voltage control of smart distribution networks, summarizes their control models, and classifies the solution methodologies. Moreover, it comments on issues that should be addressed in the future and the perspectives of industry applications.
Generation of multiple antagonistic domains along the proximodistal axis during <i>Drosophila</i> leg development (1998)

homothorax (hth) is a Drosophila member of the Meis family of homeobox genes. hth function is required for the nuclear localization of the Hox cofactor Extradenticle (EXD). We show here that there is also a post-transcriptional control of HTH by exd: exd activity is required for the apparent stability of the HTH protein. In leg imaginal discs, hth expression is limited to the domain of exd function and this domain is complementary to the domain in which the Wingless (WG) and Decapentaplegic (DPP) signals are active. We demonstrate that WG and DPP act together through their targets Distal-less (Dll) and dachshund (dac) to restrict hth expression, and therefore EXD's nuclear localization, to the most proximal regions of the leg disc. Furthermore, there is a reciprocal repression exerted by HTH on these and other DPP and WG downstream targets that restricts their expression to non-hth-expressing cells. Thus, there exists in the leg disc a set of mutually antagonistic interactions between proximal cells, which we define as those that express hth, and distal cells, or those that do not express hth. In addition, we show that dac negatively regulates Dll. We suggest that these antagonistic relationships help to convert the WG and DPP activity gradients into discreet domains of gene expression along the proximodistal axis.

Power dissipation in capacitively coupled rf discharges (1990)

The power dissipation in capacitively coupled rf discharges (Ar, 400 Pa) has been studied by impedance measurements in the 10–50 MHz frequency range. The article focuses on electrodeless discharge configurations in which the field-supplying electrodes are separated from the discharge volume by a dielectric wall, but the study of a classical electroded rf discharge is also included for comparison. The power share between bulk plasma and sheath regions is determined quantitatively using an equivalent circuit model which reflects the discharge structure. It depends strongly on both rf discharge current and frequency. For the electrodeless discharge configurations and equally for the electroded one, the fraction of power dissipated in the sheaths generally increases with increasing current and decreasing frequency. The sheath thickness derived from the impedance measurements decreases with frequency. It is nearly independent of the current for the electrodeless discharge configurations, but decreases with increasing current for the discharge configuration with internal metallic electrodes. A model for the power dissipation in the sheath is based on the current-voltage characteristics of a space-charge-limited ion current. It allows the calculation of the dissipated power Ps for operator set discharge conditions such as rf current, frequency, electrode area, and gas pressure, and predicts that Ps should vary with current I and frequency ω as (I/ω)5/2. The model is in good agreement with the experimental data. The contribution to the power dissipation from further processes besides the ion current in the sheath is also examined.
Optimal control of complex irrigation systems via decomposition-coordination and the use of augmented Lagrangian (2002)

In this paper, we consider the optimal control problem for complex irrigation systems, using a receding horizon. The idea of decomposition is introduced for the goal of both reducing the computational complexity, to comply with the system topology and the monitoring architecture. A decomposition-coordination algorithm based on the use of both an augmented Lagrangian and the duplication of variables is developed which is suitable for the optimal control of complex irrigation systems, composed of water retention systems, water supply/distribution systems using canals and pipe networks. In some conventional decomposition-coordination approaches, such as the price decomposition-coordination algorithm, the coupling constraints between subsystems or the associated Lagrange multipliers are used as coordination variables. In our case, some physical variables, such as water flow rates, are duplicated in each subsystem, where they appear. Some compatibility constraints are then introduced and their associated Lagrange multipliers are used as coordination variables. In this paper, we present the application of this approach to to the Canal de la Bourne irrigation network, which irrigates the agricultural plain of Valence (south-east of France).
Combinatorial cell–3D biomaterials cytocompatibility screening for tissue engineering using bioinspired superhydrophobic substrates (2012)

We report on the development of a new array-based screening flat platform with the potential to be used as a high-throughput device based on biomimetic polymeric substrates for combinatorial cell/3D biomaterials screening assays in the context of tissue engineering. Polystyrene was used to produce superhydrophobic surfaces based on the so-called lotus effect. Arrays of hydrophilic regions could be patterned in such surfaces using UV/ozone radiation, generating devices onto which combinatorial hydrogel spots were deposited. The biological performance of encapsulated cells in hydrogels could be tested in an in vitro 3D environment assuming that each site was isolated from the others due to the high contrast of wettability between the patterned spots and the superhydrophobic surroundings. Three different polymers-chitosan, collagen and hyaluronic acid-were combined with alginate in different proportions in order to obtain combinatorial binary alginate-based polymeric arrays. The effect of the addition of gelatin to the binary structures was also tested. The gels were chemically analyzed by FTIR microscopic mapping. Cell culture results varied according to the hydrogel composition and encapsulated cell types (L929 fibroblast cells and MC3T3-E1 pre-osteoblast cells). Cell viability and number could be assessed by conventional methods, such as MTS reduction test and dsDNA quantification. Non-destructive image analysis was performed using cytoskeleton and nuclei staining agents and the results were consistent with the ones obtained by conventional sample-destructive techniques. Briefly, L929 cells showed higher number and viability for higher alginate-content and collagen-containing hydrogels, while MC3T3-E1 showed higher cell viability and cell number in lower alginate-content and chitosan containing hydrogels. The addition of gelatin did not influence significantly cell metabolic activity or cell number in any of the encapsulated cell types.
Particle Size Analysis of Dilute Environmental Colloids by Flow Field-Flow Fractionation Using an Opposed Flow Sample Concentration Technique (1998)

An on-line concentration method has been developed for the analysis of dilute suspensions of macromolecules and particles by flow field-flow fractionation (FFF). This method, termed opposed flow sample concentration (OFSC), uses two opposing flowstreams to focus sample into a narrow band near the inlet of the flow FFF channel. Large sample volumes (up to 1 L) have been successfully loaded, concentrated, and separated in a 1 mL volume flow FFF channel. Concentration factors as high as 10(5) have been achieved. The effectiveness of OFSC flow FFF was demonstrated using mixtures of monodispersed standards such as proteins and polystyrene latex beads. Retention times, peak areas, and resolution are comparable for a 10 mL and a typical 10 microL injection volume. The applicability of the method to environmental studies was demonstrated by a separation of river water colloids.

Histamine H<sub>3</sub>receptor antagonists in relation to epilepsy and neurodegeneration: a systemic consideration of recent progress and perspectives (2012)

The central histaminergic actions are mediated by H(1) , H(2) , H(3) and H(4) receptors. The histamine H(3) receptor regulates the release of histamine and a number of other neurotransmitters and thereby plays a role in cognitive and homeostatic processes. Elevated histamine levels suppress seizure activities and appear to confer neuroprotection. The H(3) receptors have a number of enigmatic features like constitutive activity, interspecies variation, distinct ligand binding affinities and differential distribution of prototypic splice variants in the CNS. Furthermore, this Gi/Go-protein-coupled receptor modulates several intracellular signalling pathways whose involvement in epilepsy and neurotoxicity are yet to be ascertained and hence represent an attractive target in the search for new anti-epileptogenic drugs. So far, H(3) receptor antagonists/inverse agonists have garnered a great deal of interest in view of their promising therapeutic properties in various CNS disorders including epilepsy and related neurotoxicity. However, a number of experiments have yielded opposing effects. This article reviews recent works that have provided evidence for diverse mechanisms of antiepileptic and neuroprotective effects that were observed in various experimental models both in vitro and in vivo. The likely reasons for the apparent disparities arising from the literature are also discussed with the aim of establishing a more reliable basis for the future use of H(3) receptor antagonists, thus improving their utility in epilepsy and associated neurotoxicity.
Subwavelength metal-optic semiconductor nanopatch lasers (2010)

We report on near infrared semiconductor nanopatch lasers with subwavelength-scale physical dimensions (0.019 cubic wavelengths) and effective mode volumes (0.0017 cubic wavelengths). We observe lasing in the two most fundamental optical modes which resemble oscillating electrical and magnetic dipoles. The ultra-small laser volume is achieved with the presence of nanoscale metal patches which suppress electromagnetic radiation into free-space and convert a leaky cavity into a highly-confined subwavelength optical resonator. Such ultra-small lasers with metallodielectric cavities will enable broad applications in data storage, biological sensing, and on-chip optical communication.
A Method to Identify Potential Ambiguous Malay Words Through Ambiguity Attributes Mapping: An Exploratory Study (2014)

We describe here a methodology to identify a list of ambiguous Malay words that are commonly being used in Malay documentations such as Requirement Specification. We compiled several relevant and appropriate requirement quality attributes and sentence rules from previous literatures and adopt it to come out with a set of ambiguity attributes that most suit Malay words. The extracted Malay ambiguous words (potential) are then being mapped onto the constructed ambiguity attributes to confirm their vagueness. The list is then verified by Malay linguist experts. This paper aims to identify a list of potential ambiguous words in Malay as an attempt to assist writers to avoid using the vague words while documenting Malay Requirement Specification as well as to any other related Malay documentation. The result of this study is a list of 120 potential ambiguous Malay words that could act as guidelines in writing Malay sentences.
