Effect of Different Vineyard Treatments on the Phenolic Contents in Tannat (Vitis vinifera L.) Grapes and their Respective Wines

Phenolic composition of Tannat variety grapes grown in South of Uruguay and harvested during two consecutive years (1999 and 2000) was determined. The effect of the cluster thinning in setting and veraison, etephon applications, and pruning at 4 and 6 buds per rod on the phenolic composition of the grapes and their respective red wines was compared. During the harvest, which took place in the technological maturity, the phenolic maturity indices of grapes were estimated. Wines were analysed a month after the alcoholic fermentation, determining its colour and phenolic content. The different treatments had a different incidence on the total phenolic content, the total and extractable anthocyanins of the grapes, depending also on the year of harvest. There was no correspondence between the technological and phenolic maturity indices, which varied depending on the treatments and the years of harvest. The anthocyanic contents of the grapes and wines did not correlate significantly due to the diverse incidence of the environmental conditions and the harvest practices, the conditions of the maceration and the evolution of the polyphenols during the vinification.
Chalcogen(IV)−Chalcogen(II) Redox Cycles. 1. Halogenation of Organic Substrates with Dihaloselenium(IV) and -tellurium(IV) Derivatives. Dehalogenation of Vicinal Dibromides with Diaryl Tellurides

Dibromodiarylselenium(IV) species were efficient sources of positive bromine for bromolactonization of 4-pentenoic acid, bromocyclization of 4-penten-1-ol and 2-buten-1-ol, bromination of 1,3,5-trimethoxybenzene, and bromination of trans-stilbene and cyclohexene. These reactions were much slower than brominations with elemental bromine, and product distributions were brominating-agent dependent. Comparable reactions with the diphenylselenide−iodine complex were kinetically indistinguishable from reactions with elemental iodine. Diiododiaryltellurium(IV) species were efficient sources of positive iodine for iodolactonization of 4-pentenoic acid and for the iodocyclization of 4-penten-1-ol. The rates of iodolactonization decreased with increasing electron donation from substituents on the aryl groups. Dibromodiaryltellurium(IV) derivatives gave trace quantities of bromination products in reactions with olefinic substrates. However, diaryl tellurides gave debromination of erythro-1,2-dibromo-1,2-diphenyletha.
High‐Power III‐Nitride Emitters for Solid‐State Lighting

High-power, large-area InGaN/GaN quantum-well heterostructure light-emitting diodes based on an inverted, or flip-chip, configuration are described. These devices are mounted in specially designed high-power (1-5 W) packages and exhibit high extraction efficiency and low operating voltage. In the blue wavelength regime, output powers greater than 250 mW (1 x 1 mm 2 device) and 1 W (2 x 2 mm 2 device) are delivered at standard operating current densities (50 A/cm 2 ), corresponding to wall-plug efficiencies of 22%-23%. Employing phosphors for the generation of white light, these same devices achieve luminous efficiencies greater than 30 lm/W.
Structural dependence of three-phase-shift distributed feedback semiconductor laser diodes at threshold using the transfer matrix method

The three-phase-shift (3PS) distributed feedback (DFB) laser is known to have improved performance over the lambda /2 DFB laser because the spatial hole burning effect is suppressed. When optimizing the structural design of the SPS DFB laser, the threshold gain difference and the field distribution along the laser cavity have been selected as the design criteria. Using the transfer matrix method, it is found that the optimum phase-shift values and their positions are in trade-off when one attempts to optimize both the gain difference and field uniformity simultaneously.
A supramolecular superconductor θ-(DIETS)2[Au(CN)4]

A supramolecular conductor θ-(DIETS)2[Au(CN)4] [DIETS = diiodo(ethylenedithio)diselenadithiafulvalene] has been revealed to be a new superconductor with Tc = 8.6 K (onset, 10 kbar) under uniaxial strain parallel to the crystallographic c-axis.
A New Variable Diffusion Drying Model for the Second Falling Rate Period of Paddy Dried in a Rapid Bin Dryer

Abstract The objectives of this article is to propose a new drying model for the second falling rate period known as the variable diffusion controlled period that follows after the first falling rate period and to propose a new method to determine the second critical moisture content that separates these two periods. Experimental work on paddy drying at minimum fluidization velocity was carried out in a rapid bin dryer. The effects of operating temperatures (60–120°C) and bed depths (2–6 cm) on the paddy drying characteristics were investigated. It was found that the normalized drying rate of paddy was proportional to the normalized moisture content in the first falling rate period but in the second falling rate period, the normalized drying rate of the material varies exponentially with the normalized moisture content. The different relationship between the normalized drying rate and the normalized moisture content in the first and second falling rate periods indicate that two different mechanism of moisture transport are at work. The new exponential model of the second falling rate period and the linear model of the first falling rate period were found to fit the experimental data very well. Derivation from variable diffusion equation shows that the linear model is the result of constant diffusion coefficient whereas the new exponential model is the result of linear diffusion coefficient. This also implies that the first falling rate period is a constant diffusion controlled period and the second falling rate period is a variable diffusion controlled period. In addition, drying kinetics data of a drying process that fits the exponential model over a very slow drying period will show that the drying process is under the effect of a linear diffusion coefficient. It was also found that the proposed new method to determine the second critical moisture content that distinguishes between the first and second falling rate periods by using a sudden change in the value of the drying rate gradient to a much lower value at that point is more rigorous and yet simpler than the method of determining the specific location of the receding drying boundary since it is based on the behavior of the actual drying kinetic data.
EFFECT OF HUMIC SUBSTANCES ON NITROGEN UPTAKE AND ASSIMILATION IN TWO SPECIES OF PINUS

The effects of a humic fraction, with a high molecular weight (Hsp) extracted from a soil with a Fagus sylvatica vegetal cover were compared on ammonium (NH+ 4) and nitrate (NO− 3) uptake in two different coniferous species (Pinus pinaster and Pinus laricio). The activity of malate dehydrogenase (MDH; EC 1.1.1.37), glutamate dehydrogenase (GDH; EC 1.4.1.3) and phosphoenolpyruvate carboxylase (PEPC; EC 4.1.1.31) key enzymes involved in nitrogen metabolism were tested. The data obtained indicate that the humic fractions, at all concentrations, increased ammonium uptake by both species, while nitrate uptake was unaffected. In P. laricio seedlings this fraction increased only leaf malate dehydrogenase activity, while in P. pinaster seedlings an increase of glutamate dehydrogenase in leaves, and of phosphoenolpyruvate carboxylase activity in both roots and leaves was observed. These results show that humic substances stimulate only ammonium uptake and differently influence ammonium assimilation in the two species of Pinus. This diverse behavior might be related to the different environmental conditions where these two species live.
Fabrications of optically functional thin films for electric and magnetic field sensors by pulsed laser deposition

We describe the pulsed-laser deposition and characteristics of bismuth silicon oxide (BSO, Bi12SiO20) thin films and Ce-doped yttrium iron garnet (Ce:YIG, CexY3-xFe5O12) thin films for the electric and magnetic field sensor application. It was found that BSO films deposited on yttria-stabilized zirconia substrates heated at 400 degree(s)C or higher in an oxygen ambient gas were crystallized and the (310) plane was perpendicular to the substrate normal. The highly (310) oriented crystallized films were also deposited even on SiO2 glass substrates. On the other hand, crystallized Ce:YIG films were obtained by the deposition in an Ar ambient gas, and not in an oxygen ambient gas, indicating the importance of the control of the charge state of Ce ions. The magneto-optic data of Ce:YIG films are also reported.
The Life of a Trailing Spouse

In 1981, I published a paper in the first issue of the Journal of Neuroscience with my postdoctoral mentor, Alan Pearlman. It reported a quantitative analysis of the receptive field properties of neurons in reeler mouse visual cortex and the surprising conclusion that although the neuronal somas were strikingly malpositioned, their receptive fields were unchanged. This suggested that in mouse cortex at least, neuronal circuits have very robust systems in place to ensure the proper formation of connections. This had the unintended consequence of transforming me from an electrophysiologist into a cellular and molecular neuroscientist who studied cell adhesion molecules and the molecular mechanisms they use to regulate axon growth. It took me a surprisingly long time to appreciate that your science is driven by the people around you and by the technologies that are locally available. As a professional puzzler, I like all different kinds of puzzles, but the most fun puzzles involve playing with other puzzlers. This is my story of learning how to find like-minded puzzlers to solve riddles about axon growth and regeneration.
A Conversational Agent Framework with Multi-modal Personality Expression

Consistently exhibited personalities are crucial elements of realistic, engaging, and behavior-rich conversational virtual agents. Both nonverbal and verbal cues help convey these agents’ unseen psychological states, contributing to our effective communication with them. We introduce a comprehensive framework to design conversational agents that express personality through non-verbal behaviors like body movement and facial expressions, as well as verbal behaviors like dialogue selection and voice transformation. We use the OCEAN personality model, which defines personality as a combination of five orthogonal factors of openness, conscientiousness, extraversion, agreeableness, and neuroticism. The framework combines existing personality expression methods with novel ones such as new algorithms to convey Laban Shape and Effort qualities. We perform Amazon Mechanical Turk studies to analyze how different communication modalities influence our perception of virtual agent personalities and compare their individual and combined effects on each personality dimension. The results indicate that our personality-based modifications are perceived as natural, and each additional modality improves perception accuracy, with the best performance achieved when all the modalities are present. We also report some correlations for the perception of conscientiousness with neuroticism and openness with extraversion.
Neuro-Fuzzy Modeling for the Prediction of Below-Bubble-Point Viscosity

Abstract Accurate prediction of reservoir fluid is one of the important factors that needs to be determined due to it usefulness in fluid characterizations, material balance calculations, and general management of reserves. Below-bubble-point viscosity is one of the important variables that has been determined either experimentally or empirically. This work focuses on the use of neuro-fuzzy techniques to develop a below-bubble-point viscosity model using 1,693 data obtained from different oil fields in the Niger Delta, Nigeria. The data set was randomly divided into three parts with 56.3% used for training, 18.7% for validation, and 25% for testing. The accuracy of the developed model in this study was compared with some published correlations. The statistical analysis results show that the developed model outperformed existing published correlations.
Line shifts in crystal powder diffractometers

The linear relations of the neutron and X-ray optics in crystal powder diffractometers are extended with second-order terms. An expression for the angular deviation from the Bragg-peak position is derived which reduces to that of Wilson [Mathematical Theory of X-ray Powder Diffractometers (1963). Amsterdam: Philips Technical Library] for the case of characteristic X-rays in parafocusing geometry. A technique of computing second-order aberration effects is described. Line-shift formulae are given for conventional and curved-crystal diffractometers.
Monitoring of plasma processes by OES

There is often a lack of an online process monitoring to record production data and assure the quality of industrial plasma processes. By using optical emission spectroscopy (OES) this problem can easily be solved in many cases. The method does not influence the process itself, is very robust and inexpensive. OES was tested for various applications using microwave induced plasma processes to treat and coat plastic parts. It can be used to monitor the quality of oxygen plasma processes, e.g. for activating plastic parts. Another possible application is the online quality assurance of processes to produce glass‐like films by microwave induced plasma polymerization using HMDSO and oxygen as process gases. Correlations between the chemical composition, surface energy as well as roughness of the produced films and the emission of specific chemical species in the plasma could be shown.
An in situ carbon-grafted alkaline iron electrode for iron-based accumulators

An in situ carbon-grafted alkaline iron electrode prepared from the active material obtained by decomposing the α-FeC2O4·2H2O–polyvinyl alcohol (PVA) composite at 600 °C in a vacuum is reported. The active material comprises a mixture of α-Fe and Fe3O4 with the former as the prominent component. A specific discharge capacity in excess of 400 mA h g−1 at a current density of 100 mA g−1 is obtained with a faradaic efficiency of 80% for the iron electrode made from carbon-grafted active material (CGAM). The enhanced performance of the alkaline iron electrode is attributed to the increased amount of metallic iron in the active material and its concomitant in situ carbon grafting.
Optical computerized tomography of the E-H transition in inductively coupled plasmas in Ar and Ar-CF4 mixtures

We have applied optical emission spectroscopy together with computerized tomography (CT) to study the transition between E and H modes in inductively coupled plasma. Measurements were performed in pure Ar and in CF4(5%)/Ar mixture in the pressure range between 5 and 300 mTorr. It was found that the radial and azimuthal CT images of the E (capacitively coupled) mode are quite different from those of the H (inductively coupled) mode. The E mode structures show clearly the presence of capacitive coupling, while the structure of the H mode corresponds to that of the predicted induced fields. The differences diminish at low pressures due to the non-local transport of electrons. The contributions of direct and stepwise excitation are separated by using two different energy levels, 2p1 and 2p9, of Ar. In addition, the measurements obtained in electronegative gas mixture with large losses of electrons of moderate and small energy show more clearly the kinetics of excitation in the two modes and the regions where high-energy electrons are produced.
Electrochemical Stability of Desmopressin Acetate during Iontophoresis.

The electrochemical stability of desmopressin acetate (DDAVP) was investigated. After a direct current of 1 mA was passed through two electrodes chosen from platinum, silver and silver chloride, the decomposition of DDAVP was observed. The degradation products of DDAVP yielded with a Pt(anode) and AgCl(cathode) pair were similar to those observed in an anodic donor after in vivo iontophoresis. Although the Ag(anode)/Pt(cathode) degradation pattern of DDAVP was similar to that of an in vivo cathodic donor HPLC chromatogram, it was different from that of the anodic donor. In the anodic system, the stability of DDAVP was independent of the pH, and decreased with increasing concentration of NaCl.
Optical characterization of porous silicon by synchrotron radiation reflectance spectra analyses

The electronic structure of porous Si(PS) has been characterized by optical reflectance spectra analyses. The reflectance spectra of PS were measured in the photon energy range of 2–27 eV using a synchrotron radiation source. The reflectance at the low energy region was calibrated by the corresponding absolute value which was separately determined from spectroscopic ellipsometry. The spectral response of optical constants were calculated by the Kramers–Kronig analysis. Our results indicate that PS retains some of the characteristic optical features of crystalline Si, and that a blue shift in the absorption edge occurs in PS.
Performance Evaluation of Transport Protocols and Roadmap to a High-Performance Transport Design for Immersive Applications

Immersive technologies such as virtual reality (VR), augmented reality (AR), and holograms will change users’ digital experience. These immersive technologies have a multitude of applications, including telesurgeries, teleconferencing, Internet shopping, computer games, etc. Holographic-type communication (HTC) is a type of augmented reality media that provides an immersive experience to Internet users. However, HTC has different characteristics and network requirements, and the existing network architecture and transport protocols may not be able to cope with the stringent network requirements of HTC. Therefore, in this paper, we provide an in-depth and critical study of the transport protocols for HTC. We also discuss the characteristics and the network requirements for HTC. Based on the performance evaluation of the existing transport protocols, we propose a roadmap to design new high-performance transport protocols for immersive applications.
Investigation of the Spin Hamiltonian Parameters of a Tetragonal VO2+ Center in (NH4)2SbCl5

The spin Hamiltonian parameters g‖ and g⊥ and the hyperfine structure constants A‖ and A⊥ of a tetragonal VO2+ center in (NH4)2SbCl5 are investigated, using the perturbation formulas for a 3d1 ion in tetragonally compressed octahedra. In these formulas, the contributions to the spin Hamiltonian parameters from the s- and p-orbitals as well as the spin-orbit coupling coefficient of the Cl− ligand are taken into account, based on the cluster approach. According to these studies, compression of the ligand octahedra results from the strong axial crystal-fields due to the short V4+-O2− bond in the [VOCl4]2− cluster. The obtained spin Hamiltonian parameters agree well with the experimental data and need fewer adjustable parameters than the previous studies. The covalency of the studied system is also discussed.
Imprinting of polymer at low temperature and pressure

We have developed a method to pattern polymeric materials, including nonthermoplastic polymers and biomaterials, at low temperature and low pressure. In this method, plasticizers are added to increase the chain mobility of the polymers, resulting in lower imprinting temperature and/or pressure. Three established imprinting and transfer techniques were chosen to demonstrate this method: conventional nanoimprint lithography (NIL), microcontact printing (μCP), and soft ink-pad (SIP). These three techniques were used to pattern poly(3,4-ethylenedioxythiophene) (PEDOT) and chitosan. PEDOT and chitosan were chosen because both of them are nonthermoplastic polymer and therefore cannot be easily patterned using conventional NIL. Imprinting of PEDOT and chitosan films from the poly(dimethylsiloxane) mold was achieved at a low pressure of 10kPa and 25°C by controlled addition of glycerol as a plasticizer using conventional NIL; well-defined arrays of 2μm wide, 185nm high PEDOT dots have also been demonstrated by μC.
Single Modality-Based Event Detection Framework for Complex Videos

Event detection of rare and complex events in large video datasets or in unconstrained user-uploaded videos on internet is a challenging task. The presence of irregular camera movement, viewpoint changes, illumination variations and significant changes in the background make extremely difficult to capture underlying motion in videos. In addition, extraction of features using different modalities (single streams) may offer computational complexities and cause abstraction of confusing and irrelevant spatial and semantic features. To address this problem, we present a single stream (RGB only) based on feature of spatial and semantic features extracted by modified 3D Residual Convulsion Network. We combine the spatial and semantic features based on this assumption that difference between both types of features can discover the accurate and relevant features. Moreover, introduction of temporal encoding builds the relationship in consecutive video frames to explore discriminative long-term motion patterns. We conduct extensive experiments on prominent publically available datasets. The obtained results demonstrate the great power of our proposed model and improved accuracy compared with existing state-of-the-art methods.
UV-Curable, High-Shear Pressure-Sensitive Adhesives Derived from Acrylated Epoxidized Soybean Oil

Several oleo-based pressure-sensitive adhesives (PSA) were studied as substitutes for current petroleum-based PSAs; however, PSAs derived from plant oils present challenges, such as relatively low biobased contents (20–90%) and complex processes (i.e., purifying, emulsifying, and drying steps). This paper demonstrates the possibility of transparent PSAs from neat acrylated epoxidized soybean oil (AESO) via fast and simple UV free-radical polymerization with 97–100% biobased contents. In this study, we controlled the degree of free radical polymerization by modulating the amount of UV irradiation to obtain a balanced cohesion and adhesion strength for PSA applications. This AESO PSA tape on a polyester film carrier had better peel and significantly higher shear strength on glass surfaces compared with a commercial reusable tape (Post-it®, 3M, St. Paul, MN, USA). The adhesion of the AESO PSA corresponded to its dynamic rheological properties. In addition, the adhesion/cohesion behavior of the PSAs was characterized using the Johnson-Kendall-Roberts (JKR) technique.
Impact of Flue Gas Recirculation on the Efficiency of Hot-water Boilers

The topicality of the work is related to the fact that the combustion processes of various fuels, such as heat production, produce emissions that are harmful to the environment. The combustion of fossil fuels produces nitrogen oxides, which are about 10 times more dangerous than carbon monoxides. There are different methods to reduce nitrogen oxides emissions and one of effective methods is flue gas recirculation. Despite efficiency, flue gas recirculation has an impact on the efficiency of the boiler. The efficiency coefficient for the hot-water boiler was calculated with and without flue gas recirculation. The calculation with flue gas recirculation leads to a slight reduction in the efficiency factor, herewith flue gas recirculation reduced emissions of nitrogen oxides by 44,5%.
Effect of Vietnamese Text Retrieval System based on Topic Modeling

Text retrieval is an important field when the data is growing day by day. So the big problem in a text retrieval field is the large of features number. Researchers always find the ways that can reduce features in texts. In this paper, we proposed a Vietnamese text retrieval method based on text classification and topic modeling. The experimental with 220 documents shown that, our method is really effective, higher accuracy and can reduce the complexity of computing and easy to build an application system for Vietnamese text.
