Play Something by The Beatles

In certain scenarios, voice access to a music library can be a desirable method of interaction. This position paper reports experiences from a number user studies conducted in the course of a project that explored enabling voice access to a music library in mobile usage scenarios. Many of the problems encountered in the studies are clearly attributable to core speech recognition engine performance. But there is also a broad range of additional challenges that must be addressed in the context of designing such a system in order to enable a positive user experience. Author Keywords
Fluorescence Microscopy: A Technique to Study and Evaluate Spacer Fluids for Wettability Inversion

It is very important that the rock and casing surfaces are rendered water-wet before cementing operations take place in oil and gas wells. Failure to efficiently displace syntheticbased mud (SBM) or oil-based mud (OBM) and to water-wet the casing and rock formation can result in poor cementing performance that can lead to casing failures, non-productive time, costly squeeze jobs, and communication between zones. Previously, evaluation methods such as bottle cleaning tests, rheology and relative conductivity of fluid inversion from brine-in-oil (W/O) to oil-in-water (O/W) were used to qualify cement spacer efficiency. These tests do not provide information at the microscopic level and can be misleading, which can greatly affect the cement bonding process. Microscopic techniques were used to evaluate the ability of a spacer fluid to change the surface wettability from oil-wet to water-wet during the displacement of non-aqueous fluids (NAF). Bright-field and fluorescence microscopy were used to study the mechanism of the phase inversion from brine-in-oil to oil-in-water. This work discusses the evaluation of spacer fluid in different NAF spacer ratios and the transition from oilcontinuous to water-continuous fluids using microscopy. These results increase the understanding of spacer effects on drilling fluid contamination and are in good correlation with rheology and bottle cleaning test evaluations.
valuation of the performance of cellular and serological iagnostic tests for the diagnosis of tuberculosis in an alpaca

Tuberculosis (TB) in llamas and alpacas has gained importance in recent years since they are imported into the European Union mainly for serving as pets and for production of natural fibre. The intradermal tuberculin test has been widely used for diagnosis of TB in these species showing lack of sensitivity (Se) although little information has been previously reported evaluating the effect on its performance of different PPD inoculation sites and time of readings. Moreover, different cost-effective serological assays have been developed in the recent years for TB diagnosis in camelids obtaining a variety of results and, for this reason, new assays still being developed. The main objectives of this study were: (1) to evaluate the performance of the intradermal tuberculin test using different inoculation sites (axillary, prescapular and cervical) and times of reading (72 and 120 h) and (2) to test a novel serological assay based on MPB83 antigen in a Mycobacterium bovis naturally infected alpaca herd in Spain. In regards to skin test, single intradermal tuberculin (SIT) test at the prescapular site and reading at 72 h showed the highest proportion of testpositive-culture positive animals among all culture positive animals (T+/C+), ranging from 53.8% (95% CI, 37.2–69.9) to 80% (95% CI, 44.4–97.5) using a more stringent interpretation than typically prescribed although, in general, low T+/C+ was achieved using both SIT and single comparative intradermal tuberculin (SCIT) tests alone. T+/C+ of the serological assay increased using samples collected 15–30 days after PPD injection [76.9% (95% CI, 60.7–88.9) – 100% (95% CI, 69.2–100)]. The best results of T+/C+ were obtained applying in parallel the most sensitive SIT test and serology using samples collected 15–30 days after PPD 5% CI, inoculation [90% (9 of serology in parallel wi infected animals. ∗ Corresponding author.

Modeling and formulation of a novel microoptoelectromechanical gyroscope

This paper proposed a novel design of microgyroscope based on MEMS structures and optic interferometric microdisplacement measurement technique. The gyroscope consists of microvibrator and interferometric readout. Using Coriolis force, the vibrator transfers the system rotation into a forced vibration; the induced vibration can be sensed by the interferometric microdisplacement measurement system. The optic measurement system has two mirrors which will reflect two rays into a detector. The comprehensive studies on the formulation and analysis of the proposed gyroscope have been undertaken; two key sensor equations have been derived in the first time in the world: (1) relation between rotation and phase shift of light Δϕ = (4πl0/λ) + (8π/λ)(xmaxQy/ωy)Ω(t) sin(ωdt), (2) relation between rotation and interferometric intensity of light I(t) ≅ (8π/λ)(xmaxQy/ωy)Ω(t) sin(ωdt) sin(4πl0/λ). The comparison of the proposed gyroscope and well-know Sagnac formulation has been investigated; it shown that the proposed model is much better than Sagnac ones. The new model has finally get rid of needing very long fiber in the case of Sagnac gyroscope. The innovative model gives a new hope to fabricate high accurate and cheaper gyroscope. To date, the proposed gyroscope is the most accurate gyroscope.
Technical Report TR-2010-019 A Variational Data Assimilation Procedure for the Incompressible Navier-Stokes Equations in

Including data into numerical simulations has always been an issue of paramount relevance in the prediction of fluid geophysics phenomena, especially in weather forecast and oceanography, since a long time. Due to advanced and efficient techniques in biomedical imaging we can now collect a huge amount of measurements also for the cardiovascular system. Our goal is to use these in general noisy and sparse data to get an accurate approximation of the blood flow in vessels in order to predict physical quantities of medical relevance. The combination of measurements and governing principles is known in literature as Data Assimilation (DA). In this work we propose a DA technique for including noisy measurements of the velocity field into the simulation of the Navier-Stokes Equations (NSE) driven by hemodynamics applications. Specifically, the technique we present is formulated as an inverse problem where we use a Discretizethen-Optimize approach to minimize the misfit between the recovered velocity field and the data, subject to the state equations, i.e. the incompressible NSE. The discretization is carried out by means of the Finite Element method. The DA procedure for this nonlinear problem is a combination of two approaches: the Newton method for the NSE, a common iterative procedure for the treatment of the nonlinear advection term, and the DA procedure we designed and tested for linear problems, specifically for the Oseen problem. In this paper we discuss in detail conditions on the location of velocity measurements that guarantee the well-posedness of the minimization process for the Oseen problem. Numerical results, with both noise-free and noisy data (either known by analytical solution or generated synthetically solving a forward problem), are presented to certify the theoretical analysis. Moreover, we consider the presence of the noise on 2D non-trivial geometries and its impact on non-primitive variables of medical interest such as the wall shear stress.
Cognitive Risk Factors of Social Anxiety

This study aimed to examine a model of cognitive risk factors, which were Fear of Negative Evaluation, Intolerance of Uncertainty and Shame in predicting social anxiety. Furthermore, this study also aimed to investigate any possible interactions among those factors in predicting social anxiety. Of 112 participants, nearly one half of whom were university students, completed a series of online questionnaires. Hierarchical regression via SPSS version 21.0 to examine the relative contribution of IU and interaction analyses using PROCESS macro for SPSS to investigate any possible interactions were performed. IU and FNE each consistently predicted social anxiety whilst shame unexpectedly did not. An interaction between IU and FNE was detected. These findings extend our understanding of the critical role of FNE and IU in predicting social anxiety and interestingly, FNE and IU strengthen each other in predicting social.
Can Health Status and Self-Esteem Predict Gratitude in Adult Females?

Gratitude is often considered a sub-sector of positive psychology. The aim of this study was to examine whether health status and self-esteem could predict gratitude scores in a sample of women. A non-clinical female sample (N = 200) completed self-reported measures online. A hierarchical multiple regression analysis was used to examine whether health status and self-esteem could significantly predict gratitude scores. Findings revealed that health status did not significantly predict gratitude scores in the sample of women in the current study. However, self-esteem was found to statistically predict gratitude scores, suggesting that women with low self-esteem levels were more likely to have lower gratitude scores, which is supported by previous research. The implications of this finding may benefit treatment programs, to increase self-esteem levels in individuals to achieve higher gratitude levels, resulting in various benefits for overall health and well-being.
Analysis of Well-Tests in Balcova-Narlidere Geothermal Field, Turkey

In this work, analyses of two injection/falloff and two pressure drawdown tests in the Balcova-Narlidere geothermal field, Turkey, are presented. The pressure data are analyzed by using modern well-test analysis techniques, such as pressure derivative to identify flow regimes exhibited by the data and regression analysis to estimate formation parameters. The pressure tests conducted, in general, show that the tested wells produce from a “reservoir” with a complex network of system consisting of communicating and noncommunicating fractures/faults. For example, the pressure-derivative behavior of the wells BD2, BD-5 and BD-7 resembles the behavior of a well located near a high-conductivity communicating fault zone, while the pressure-derivative behavior of the BD-6 well indicates that the well is located near a sealing (non-communicating) fault zone. The estimated values of flow capacities (kh) from the analyses of well-test pressure data for these four wells changed from 3 to 121 darcy-m.
A configurable SRAM with constant-negative-level write buffer for low-voltage operation with 0.149µm2 cell in 32nm high-k metal-gate CMOS

This paper presents a configurable SRAM for low-voltage operation with constant-negative-level write buffer (CNL-WB) and level programmable wordline driver for single supply (LPWD-SS) operation. CNL-WB is suitable for compilable SRAMs and it improves write margin by featuring an automatic BL-level adjustment for configuration range of four to 512 cells/BL using a replica-BL technique. LPWD-SS optimizes the tradeoff between disturb and write margin of a memory cell, allowing a 60% shorter WL rise time than that of the conventional design [1] at 0.7V. A test-chip is fabricated in a 32nm high-k metal-gate CMOS technology with a 0. 149µm2 6T-SRAM cell. Measurement results demonstrate a cell-failure rate improvement of two orders of magnitude for an array-configuration range of 64 to 256 rows by 64 to 256 columns.

Response of summer rainfall over China to spring snow anomalies over Siberia in the NCEP CFSv2 reforecast

Predictions of the snow water equivalent (SWE) over Siberia in spring (March–April–May) and its relationship with summer (June–July–August) precipitation over China are investigated using the reforecast (1983–2010) from the National Centers for Environmental Prediction (NCEP) Climate Forecast System version 2 (CFSv2). The CFSv2 for 1 month lead (LM0) predicts the leading pattern of Eurasian SWE in spring well, characterized by homogeneous variations over most of Eurasia centred on Siberia. Overall, the CFSv2 for LM0 exhibits a reasonable level of prediction skill for variations of Siberian spring SWE, but the initial SWE in the CFSv2 shows a dominant effect on the reforecasted Siberian SWE climatology. Using the initial condition in April, the CFSv2 can predict the SWE over Siberia in May and the corresponding summer rainfall pattern over China. Positive SWE in May in the CFSv2 is associated with negative summer rainfall anomalies in South and North China and part of Northeast China, and with positive anomalies between the Yangtze River and the Huaihe River and over Inner Mongolia and parts of the north of the Tibetan Plateau and southeastern Tibetan Plateau. The result is consistent with observed features.
Fungal diversity and specificity in Cephalanthera damasonium and C. longifolia (Orchidaceae) mycorrhizas

Orchids depend on mycorrhizal fungi for their nutrition, at least in the early stages of their growth and development, and in many cases throughout the life. In spite of the increasing number of studies describing fungal diversity in orchids, there is still more to be learnt about the identity of fungal partners and specificity in orchid mycorrhizal associations. We investigated the fungal communities associated with the roots of Cephalanthera damasonium (Mill.) Druce and C. longifolia (L.) Fritsch adult plants, using morphological methods and fungal internal transcribed spacer‐DNA polymerase chain reaction amplification, cloning, and sequencing. A range of fungi belonging to Basidiomycota and Ascomycota was uncovered in the roots of the two investigated orchid species, showing a low degree of mycorrhizal specificity. At least 11 fungal taxa, including Cenococcum geophilum Fr. , Ceratobasidium sp. , Exophiala salmonis J. W. Carmich. , Hymenogastraceae, and Sebacinaceae colonized C. damasonium roots, while approximately 9 fungal types, such as Bjerkandera adusta (Willd.) P. Karst. , Phlebia acerina Peck, Sebacinaceae, Tetracladium sp. , and Tomentella sp. associated with C. longifolia. Phylogenetic and statistical analyses indicated significant differences in the fungal communities associated with the two studied Cephalanthera species, as well as distinct mycorrhizal partners associated with each orchid plant. Our results strongly suggest that both C. damasonium and C. longifolia are generalist in their mycorrhizal associations.

Prediction of Wax Deposition Risk of Malaysian Crude from Viscosity-Temperature Correlation for Dead Crude

Malaysian oil production occurs offshore and extreme environment, its cold temperature could make wax deposition problems almost inevitable as most of the oilfields approaching their matured stage of production. Wax deposition had demonstrated a critical concern in the quest to increase oil recovery from producing reservoirs. The unwanted effect of wax deposition could cause reduced productivity, complete plugging of pipeline, minimum profitability and other hazardous risks; while its mitigation operations and production losses are expensive and economically unjustified. This study employed Standing correlation model for the viscosity-temperature relationship of dead crude to predict wax crystallization point. The predicted wax appearance points were in good agreement with the experimental values of the Malaysian dead crude oils, with average absolute deviation (AAD %) of 11.71%. However, the Standing model varied significantly with the measured viscosity data. The main goal of this work was to predict wax deposition threat or related problems in Malaysian
Quantitative Determination of Phytate and Inorganic Phosphorus for Maize Breeding

Phytate is the dominant storage form of phosphorus (P) in mature cereal and oil grains. Phosphorus bound in phytate is nutritionally unavailable to monogastric animals and thus contributes to water pollution because it is excreted in the waste. Also, phytate can chelate certain minerals and exacerbate human mineral deficiencies. Our primary objective was to develop a rapid and inexpensive method of measuring phytate and inorganic P (P i ) concentrations in maize (Zea mays L.). The procedure reported herein was derived from previously published assays and used to screen 50 inbred lines to determine its potential in a selection program. Grain yield, protein, oil, methionine, lysine, tryptophan, and kernel weight were also measured. Field repeatability values for phytate and P i (0.78 and 0.91, respectively) suggest that our protocol can be used to make heritable measurements on both traits. Phytate measurements taken with the procedure reported herein matched closely those obtained through ion exchange. The combination of adequate precision and simplicity make this method ideal for breeders interested in improving P i and phytate levels simultaneously. The positive phytate:protein correlation reported commonly was also detected in this study. A relationship between phytate and kernel weight indicates that selection for low phytate may result in larger kernels.
Comparison of the performance of local, gradient-corrected, and hybrid density functional models in predicting infrared intensities

Density functional theory has been used to calculate infrared (IR) intensities for a series of molecules (HF, CO, H2O, HCN, CO2, C2H2, H2CO, NH3, C2H4, CH2F2, CH2Cl2, and CH2Br2) in an effort to evaluate relative performance of different functionals. The methods employed in this study comprise most of the popular local, gradient-corrected, and hybrid functionals, namely, S-VWN, S-PL, B-LYP, B-P86, B-PW91, B3-LYP, B3-P86, and B3-PW91. Calculations were carried out using various qualities of split valence basis sets augmented with diffuse and polarization functions, both to determine basis set dependence and to evaluate the limit performance. Computed intensities were compared with results from conventional correlated ab initio methods (MP2 and QCISD). Hybrid functionals give results in closest agreement with QCISD over the other methods surveyed. Local and gradient-corrected methods performed remarkably alike, both are comparable to MP2, and outperform Hartree–Fock. Hartree–Fock intensities can be dramatic.

The effect of vacuum annealing on graphene

The effect of vacuum annealing on the properties of graphene is investigated by using Raman spectroscopy and electrical measurement. Heavy hole doping on graphene with concentration as high as 1.5 × 1013 cm−2 is observed after vacuum annealing and exposed to an air ambient. This doping is due to the H2O and O2 adsorption on graphene, and graphene is believed to be more active to molecular adsorption after annealing. Such observation calls for special attention in the process of fabricating graphene-based electronic devices and gas sensors. On the other hand, because the quality of graphene remains high after the doping process, this would be an efficient and controllable method to introduce heavy doping in graphene, which would greatly help on its application in future electronic devices.

Cellulose nanomaterials: size and surface influence on the thermal and rheological behavior

Cellulose nanocrystals (CNC) and nanofibrils (CNF) were obtained by acid hydrolyzis and mechanical treatment, respectively, of cellulosic fibers from paper. Additionally, surface modification was performed for CNC by neutralization (NaOH) and oxidation (TEMPO). The thermal stability, surface properties and rheological behavior of these nanomaterials were compared. A clear difference in CNC surface was found upon neutralization and oxidation treatments, leading to distinct thermal behaviors. Optical and rheological properties were found to be predominantly by the particles size, being strongly affected by inertial effects.
