Effects of the Launch Speed on Hydrodynamic Force of the Underwater Vehicle Vertical Launch with the Gas Curtain

The vertical launch of the gas curtain is a new underwater launch technology. The gravity effect of the launch speed on hydrodynamic characteristics of the underwater vehicle vertical launching by using the gas curtain has been studied by adopting the multiphase VOF model and the standardturbulence model. The relationship between the launch speed and the shape of the underwater vehicle has been achieved by using the numerical simulation. The relationships between the launch speed and the hydrodynamic characteristics of the underwater vehicle vertically launching from the tube, navigating in water and exiting water have been investigated by using numerical simulation. The hydrodynamic characteristics of underwater vehicle vertical launching by using the gas curtain method are small. The effects of the launch speed on the hydrodynamic characteristics of the underwater vehicle vertical launching in the gas curtain are small.
Simulations of the Atomic Beam Transport in an Atomic Beam Source under the Influence of Spin-Selective Sextupole Magnets

Polarized internal gas targets are important tools in spin-physics experiments at par- ticle accelerators. For many experiments it is imperative to get the highest possible target density. Research in recent decades, however, led only to marginal increase of the intensity of atomic beam sources (ABS), which constitute the main factor in in- creasing the target density. The main problem, hindering further improvement, is the complexity of the processes in the ABS, which prevents a complete description of all ef- fects. A particularly big challenge is the description of the change in ﬂow regime from laminar to molecular during the formation of the atomic beam by the nozzle. Now, with ever increasing computer power, it becomes possible to simulate all the processes in a complete ABS and to use algorithms to optimize the device. The present thesis summarizes the important effects in polarized internal gas targets and describes the implementation of a new computer program, which was interfaced with an optimization algorithm. The program is based on OpenFOAM 1.7. 1 and uses the Direct Simulation Monte Carlo (DSMC) method to simulate the gas ﬂow. Besides a generic interface for magnetic ﬁelds which act on the magnetic moments of the atoms, many important effects like recombination and spin-exchange collisions are included in the program. Furthermore, a generic framework for optimization is implemented. It can be used to optimize very different problems with different optimization algo- rithms. Currently, Adaptive Simulated Annealing (ASA) is implemented together with the capability to handle the optimization of an ABS. All parts of the program were tested and results are provided. Although the execution time of a simulation run is still very long, the new program might become a valuable tool for simulating and op- timizing polarized internal gas targets. This will lead to better statistics in experiments and will enable certain new experiments.
Consumers’ Preference and Willingness-To-Pay for Different Varieties of Pepper in Osun State, Nigeria

The study was conducted to assess consumers’ preference and willingness to pay for different pepper varieties in Osun State, Nigeria. The study used the major pepper types – Capsicum chinenses (Rodo), C. annum (Tatase), C. frutescens (Sombo) and C. pubescens (Bawa), being sold in the markets in Osun State, Nigeria. A multistage sampling technique was used to collect data from 100 respondents. The primary data collected were analysed using descriptive and inferential statistics. The study showed that consumers mostly preferred and were willing to pay more for C. chinenses (Rodo) than any other types of pepper. Household size, primary occupation, total household income, availability and meal-making ability of pepper were the factors that influenced consumers’ preference for the different varieties of pepper while the willingness to pay for pepper varieties by consumers was influenced by affordability, availability, taste and thickness. The study recommends that since availability and affordability influenced preference and willingness to pay for pepper varieties, policies should be aimed at increasing farmers’ production as this will ensure that pepper is readily available and affordable for consumers.
Reversible phosphorylation of cyclin T1 promotes assembly and stability of P-TEFb

The positive transcription elongation factor b (P-TEFb) is a critical coactivator for transcription of most cellular and viral genes, including those of HIV. While P-TEFb is regulated by 7SK snRNA in proliferating cells, P-TEFb is absent due to diminished levels of CycT1 in quiescent and terminally differentiated cells, which has remained unexplored. In these cells, we found that CycT1 not bound to CDK9 is rapidly degraded. Moreover, productive CycT1:CDK9 interactions are increased by PKC-mediated phosphorylation of CycT1 in human cells. Conversely, dephosphorylation of CycT1 by PP1 reverses this process. Thus, PKC inhibitors or removal of PKC by chronic activation results in P-TEFb disassembly and CycT1 degradation. This finding not only recapitulates P-TEFb depletion in resting CD4+ T cells but also in anergic T cells. Importantly, our studies reveal mechanisms of P-TEFb inactivation underlying T cell quiescence, anergy, and exhaustion as well as proviral latency and terminally differentiated cells.
Polycaprolactone and polycaprolactone triol blends to obtain a stable liquid nanotechnological formulation: synthesis, characterization and in vitro – in vivo taste masking evaluation

Abstract The use of polymeric blends is a potential strategy to obtain novel nanotechnological formulations aiming at drug delivery systems. Saquinavir, an antiretroviral drug, was chosen as a model drug for the development of new stable liquid formulations with unpleasant taste masking properties. Three formulations containing different polymeric ratios (1:3, 1:1 and 3:1) were prepared and properly characterized by particle size distribution, zeta potential, pH, drug content and encapsulation efficiency measurements. The stability was verified by monitoring the zeta potential, particle size distribution, polydispersity index and drug content by 90 days. The light backscattering analysis was used to early identify possible phenomena of instability in the formulations. The in vitro drug release and saquinavir cytotoxicity were evaluated. The in vitro and in vivo taste masking properties were studied using an electronic tongue and a human sensory panel. All formulations presented nanometric sizes around 200 nm and encapsulation efficiency above 99%. The parameters evaluated for stability remained constant throughout 90 days. The in vitro tests showed a controlled drug release and absence of toxic effects on human T lymphocytes. The electronic tongue experiment showed taste differences for all formulations in comparison to drug solutions, with a more pronounced difference for the formulation with higher polycaprolactone content (3:1). This formulation was chosen for in vivo sensory panel evaluation which results corroborated the electronic tongue experiments. In conclusion, the polymer blend nanoformulation developed herein showed the promising application to incorporate drugs aiming at pharmaceutical taste-masking properties.

3D FDTD method for arbitrary anisotropic materials

A generalized 3D finite‐difference time‐domain (FDTD) method for the modeling of electromagnetic wave interaction with a full anisotropic media is presented. The proposed formulation is applied to three configurations: a microstrip patch antenna with anisotropic substrates, weakly magnetic ferrite absorbers with punctured holes, and a waveguide loaded with heterogeneous anisotropic magnetic materials. Computed results show that anisotropic material can have great effects on system properties and can add another degree of design freedom. © 2006 Wiley Periodicals, Inc.

Genetic risk scores and dementia risk across different ethnic groups in UK Biobank

Background Genetic Risk Scores (GRS) for predicting dementia risk have mostly been used in people of European ancestry with limited testing in other ancestry groups. Methods We conducted a logistic regression with all-cause dementia as the outcome and z-standardised GRS as the exposure across diverse ethnic groups. Findings There was variation in frequency of APOE alleles across ethnic groups. Per standard deviation (SD) increase in z-GRS including APOE, the odds ratio (OR) for dementia was 1.73 (95%CI 1.69–1.77). Z-GRS excluding APOE also increased dementia risk (OR 1.21 per SD increase, 95% CI 1.18–1.24) and there was no evidence that ethnicity modified this association. Prediction of secondary outcomes was less robust in those not of European ancestry when APOE was excluded from the GRS. Interpretation z-GRS derived from studies in people of European ancestry can be used to quantify genetic risk in people from more diverse ancestry groups. Urgent work is needed to include people from diverse ancestries in future genetic risk studies to make this field more inclusive.
STRUCTURAL FLEXIBILITY OF THE SHUTTLE REMOTE MANIPULATOR SYSTEM MECHANICAL ARM

The dynamics of the 15m long remote manipulator sys tem which is the major element of the payload deployment and retrieval system of the orbiter of the NASA Space Transportation System are, by virtue of the large range of payload masses to be manoeuvred throughout the o perating envelope, significantly affected by the flexibility of the structural components. The paper addresses the finite-element analyses and computer simulations which were carried out by the Canadian design team to a scertain both that arm and orbiter induced manoeuvring loads were maintained below design limits, and that adequate level of stability and controllability were achieved throughout the dynamic operating envelope of the system in the presence of structural flexibility influences.
Discrete Fourier transform-based parametric modal identification from ambient data of the power system frequency

This study proposes a discrete Fourier transform (DFT)-based parametric identification method by using a difference sequence between two sets of frequency data. An autocorrelation function of the frequency difference sequence can be represented as a linear combination of exponentially decaying sinusoidal functions, whose natural frequencies and damping ratios are equal to those of interarea modes. These modal parameters are calculated from the Laplace transform coefficients of the autocorrelation function. The coefficients are estimated by curve-fitting the DFT values of the autocorrelation function. The proposed method is compared with the modified extended Yule Walker method through simulations on signal-to-noise ratio. Finally, the feasibility of the proposed method is shown by identifying real power systems from frequency data of the frequency monitoring network system.
Evaluation of a Spelling Intervention Program for Third Graders at Risk for Learning Disabilities

Abstract The development of spelling skill is an intricate process for children with or at risk of Specific Learning Disabilities and requires targeted interventions. This problem exacerbates in the Greek orthographic system owning to its high complexity. The current study presents a novel spelling intervention program for Greek 3rd graders at risk of Specific Learning Disabilities, which was founded upon the principles of Direct Instruction and encompassed evidence-based practices. The effectiveness of the proposed 16-h intervention program was investigated via its implementation in Greek resource rooms by the corresponding teachers. The children were randomly assigned into the intervention (n = 39) and the comparison group (n = 34). Standardized tests were used for children’s assessment during pretests, post-tests I, and post-tests II. Importantly, the results obtained via ANOVA demonstrated that the children of the intervention group showed a statistically significant improvement in spelling contrary to the comparison group. Additionally, the impact of the intervention program on children’s decoding and fluency skills was examined, yielding enhanced, yet, no statistically significant outcomes. The educational implications of the related findings are also discussed. Overall, the proposed study provides tangible evidence that spelling can be taught effectively to SLD children.
Observations of Nutrient Supply by Mesoscale Eddy Stirring and Small‐Scale Turbulence in the Oligotrophic North Atlantic

Sustaining biological export over the open ocean requires a physical supply of nutrients to the mixed layer and thermocline. The relative importance of diapycnal mixing, diapycnal advection, and isopycnal stirring by mesoscale eddies in providing this nutrient supply is explored using a field campaign in oligotrophic waters in the subtropical North Atlantic, consisting of transects over and off the mid‐Atlantic ridge. Eddy stirring rates are estimated from the excess temperature variance dissipation relative to the turbulent kinetic energy dissipation, and using eddy statistics from satellite observations combined with 9‐month‐long mooring data. The vertical nutrient fluxes by diapycnal mixing, diapycnal advection, and isopycnal mesoscale eddy stirring are assessed using nitrate measurements from observations or a climatology. Diapycnal mixing and advection provide a nutrient supply within the euphotic zone, but a loss of nutrients within the upper thermocline. Eddy stirring augments, and is comparable to, the diapycnal transfer of nutrients within the summertime upper thermocline, while also acting to replenish nutrients within the deeper parts of the thermocline. The eddy supply of nitrate is relatively small in the center of the subtropical gyre, reaching up to 0.06 mol N m−2yr−1, but is likely to be enhanced on the flanks of the gyre due to larger isopycnal slopes and lateral nitrate gradients. The nutrient supply to the euphotic zone is achieved via a multistage mechanism: a diapycnal transfer of nutrients by small‐scale turbulence to the euphotic zone, and an isopycnal stirring of nutrients by mesoscale eddies replenishing nutrients in the upper thermocline.

A miniature Q-band low noise amplifier (LNA) using 0.13-/spl mu/m standard mixed signal/radio frequency complementary metal-oxide-semiconductor (CMOS) technology is presented in this letter. This three-stage common source thin-film microstrip LNA achieves a peak gain of 20dB at 43GHz with a compact chip size of 0.525mm/sup 2/. The 3-dB frequency bandwidth ranges from 34 to 44GHz and the minimum noise figure is 6.3dB at 41GHz. The LNA outperforms all the reported commercial standard CMOS Q-band LNAs, with the highest gain, highest output IP3, and smallest chip size.
Scattering characteristics of targets at different wavelengths based on Kirchhoff scalar approximation theory

Bi-directional reflection distribution function (BRDF) is a common method to study the laser scattering characteristics of targets, and it is an important parameter for the theoretical demonstration of laser active detection, target recognition and classification. Scholars at home and abroad have proposed many mature BRDF models to describe the scattering characteristics of different targets. However, almost all of these models do not take into account the effect of incident wavelength on scattering characteristics. In addition, limited by the frequency modulation range of the laser, the existing BRDF measurement devices cannot obtain the BRDF data of the target at any wavelength, which restricts the application of the existing BRDF model. In view of this limitation, a method is proposed to calculate the unknown wavelength BRDF data using the BRDF measurement data of known wavelengths. Firstly, based on the Kirchhoff approximation theory, the spatial distribution of the scattered light field of the metal aluminum target at any wavelength was simulated and analyzed. Secondly, the error of the theoretical simulation model was analyzed through the experimental data. Finally, the BRDF data at any wavelength were calculated using the simulation data and the experimental data with known wavelengths. The final results showed that at the 1064nm wavelength, the RMSE value of the calculated data obtained by this method is 0.3553, which is 0.2233 smaller than the RMSE value of the simulation data.This method is effective in calculating the BRDF of metal aluminum targets at different wavelengths.
Packaging compatible microtransformers on a silicon substrate

Surface micromachining techniques have been utilized to realize microtransformers on a silicon substrate for integration with a multi-chip package, allowing compact integration with chips, complementary metal-oxide-semiconductor (CMOS) circuits, sensors, and other components. Two different microtransformers comprised of two-layer vertically stacked spiral-type copper conductor lines and permalloy magnetic cores have been designed, fabricated, and characterized. Low temperature processes have been chosen for fabricating these microtransformers. The fabricated microtransformers have been tested and compared for finding out better geometries for integrated microtransformers. Electroplated thick permalloy cores and copper coils have been utilized for obtaining better performance characteristics in the intermediate frequency range. The fabricated microtransformers have a turn ratio of 1, coupling coefficient of 0.85, DC resistance of 3.3 /spl Omega/, and gain characteristics of -5 dB, respectively. They are suitable for integrated power converter applications, since these devices have also high current carrying capability (up to 2 A steady DC current).
Aggregation technique for networks with power law traffic and application to accelerated simulation

The authors present an accelerated simulation technique for packetised networks, and examine the accuracy and speedup obtained when it is used in studies of power law traffic, including cases where the sojourn times have been truncated to imitate real network operation. The aggregation concept has also been applied to an end-to-end path, where both the number of end-to-end nodes and the number of traffic sources at a node are aggregated. It is shown that very accurate results are obtained in combination with significant simulation acceleration.
