The Study on the Nutritive Components and Water-Soluble Protein Extraction of Juglans mandshurica Maxim Kernel

This study compared the main compositions of the different areas walnuts. A large diversity was found in moisture, ash, total fat and crude protein content. We got four kinds of walnuts from different areas of northeast China (A: Suifenhe Heilongjiang B: Yichun Heilongjiang C: Mudanjiang Heilongjiang D: Baishan Jilin). The sample D has the most moisture compared the others, 6.563%. The ash and total fat contents of the sample C are more than others, respectively 2.96% and 56.42%. For the crude protein, the kind from sample A is the most, 34.349%. The experiment also studied the protein extraction of the degreased kernel by distilled water. During the extracting process, three main factors including ratio of solid to liquid, exacting time and temperature were studied by using single factor analysis method. According to orthogonal test results, when the solid-liquid ratio, time and temperature were respectively 1/45, 3.5h, 45°C, the material (WKCD) had the highest protein extraction ratio 57.62%.

Effect of the Gmaw and the Gmaw-P Welding Processes on Microstructure, Hardness, Tensile and Impact Strength of Aisi 1030 Steel Joints Fabricated by ASP316L Austenitic Stainless Steel Filler Metal

In this study, medium-carbon steel (AISI 1030) plates of 10 mm thickness, were welded by using the synergic controlled pulsed (GMAW-P) and manual gas metal arc (GMAW) welding techniques. Constant wire feed speed, voltage, welding speed and gas flow rates (3.2 m/min, 22.5 V, 4 mm/s, 16 1/min) and ASP316L austenitic stainless steel filler metal were used in these techniques. The interface appearances of the welded samples were examined by optical microscopy (OM), scanning electron microscopy (SEM), energy dispersive spectrometry (EDS) and X-Ray diffraction (X-RD). In order to determine mechanical properties of samples, the tensile, impact and microhardness tests were conducted. The GMAW-P joints of AISI 1030 steel couples showed superior tensile strength, less grain growth and narrower heat affected zone (HAZ) when compared with GMAW joints, and this was mainly due to lower heat input, fine fusion zone grain and higher fusion hardness.
Output feedback sliding mode control of time delay systems with bounded disturbances

This paper considers linear time delay systems with bounded disturbances that are not necessarily matched. A static output feedback sliding mode controller is designed. The existence problem is solved by determining a sliding surface that minimizes the ultimate bound of the reduced-order dynamics in the presence of time varying delay and unmatched disturbances. Linear matrix inequalities (LMIs) are derived to compute the sliding surface via a descriptor approach. A controller that guarantees ultimate boundedness of the full-order system and ensures that the sliding surface is reached in finite time is derived using LMIs. The method facilitates sliding mode controller design for systems with polytopic uncertainties, which may appear in all blocks of the system matrices. A time delay model with polytopic uncertainties from the literature illustrates the efficiency of the proposed method and the advantages of the sliding mode controller over the linear scheme.
Cognitive Diagnostic Analysis of Reading Comprehension Items: The Case of English Proficiency Assessment in Saudi Arabia

This paper deals with cognitive diagnostic analysis of the reading comprehension part of the Standardized Test of English Proficiency (STEP-RC) developed and administered by the National Center for Assessment in Saudi Arabia. The Least Squares Distance Model (LSDM) was used to obtain probabilities of correct performance on cognitive attributes of STEP-RC items across levels of the underlying ability measured by the test. Among other results, cutting scores on the scale for correct performance on targeted attributes are provided for the purposes of criterion-based diagnostic decisions. Aspects of the validity of the cognitive attributes are also examined in the LSDM framework. The methodology and procedures illustrated in this study can be applied in different areas of assessment and cognitive analysis.
Adrenomedullin, an Endogenous Peptide, Counteracts Cardiovascular Damage

Background—Adrenomedullin (AM), a potent vasodilator peptide, is produced by posttranslational splicing of pro-adrenomedullin together with proadrenomedullin N-terminal 20 peptide (PAMP), another hypotensive peptide. Although both AM and PAMP have the potential not only to decrease blood pressure but also to protect organs from damage, there is no direct evidence for their individual physiological roles in vivo. Methods and Results—Using knockout mice with the disruption of AM peptide alone, we investigated the organ-protective effect of AM. Although the AM−/− mutation in mice was embryonic lethal without any apparent phenotypic changes, AM+/− mice were viable and fertile; plasma and organ AM concentrations were almost half of those in AM+/+ mice. With the administration of angiotensin II (Ang II) on a high-salt diet for 12 days, marked perivascular fibrosis and intimal hyperplasia were found in coronary arteries of Ang II/salt–treated AM+/− mice, without the AM upregulation that was observed in Ang II/salt–treated AM+/+ mice. In AM+/− mice, Ang II/salt loading increased both urinary excretion of 8-hydroxydeoxyguanosine and isoprostane, markers of oxidative stress. Consistently, immunostaining of both p67phox and gp91phox, subunits of NAD(P)H oxidase and 3-nitrotyrosine, the metabolites of reactive oxygen species (ROS), and the generation of ROS measured by electron spin resonance spectroscopy apparently increased in the Ang II/salt–treated heart. These data suggested that the overproduction of oxidative stress might be involved in the cardiovascular changes induced by Ang II/salt loading. Conclusions—The evidence presented supports the hypothesis that endogenous AM possesses a protective action against cardiovascular damage, possibly through the inhibition of oxidative stress production.
Learning Simple Auctions

We present a general framework for proving polynomial sample complexity bounds for the problem of learning from samples the best auction in a class of "simple" auctions. Our framework captures all of the most prominent examples of "simple" auctions, including anonymous and non-anonymous item and bundle pricings, with either a single or multiple buyers. The technique we propose is to break the analysis of auctions into two natural pieces. First, one shows that the set of allocation rules have large amounts of structure; second, fixing an allocation on a sample, one shows that the set of auctions agreeing with this allocation on that sample have revenue functions with low dimensionality. Our results effectively imply that whenever it's possible to compute a near-optimal simple auction with a known prior, it is also possible to compute such an auction with an unknown prior (given a polynomial number of samples).
Optimization of Direct Power Control in Doubly-Fed Induction Machine (DFIM) using PSO Algorithm

Doubly-fed induction generators (DFIG) are widely used in wind power plants due to several advantages such as partial rating converter, the ability of decoupled active and reactive power control, etc. This paper discusses modeling and control of doubly-fed induction generator using direct power control method. Direct power control method is based on active and reactive power control that can be controlled independently. This method has better dynamic rather than other methods. In this paper the model of doubly-fed induction machine has been expressed with some relations. We have used an intelligent optimization method named PSO for optimization of control parameters at the PI controller used in this control system. PSO methods avoid the shortcoming of premature convergence and can obtain a solution with better computation efficiency. Simulation results based on this method has been compared with the results based on trial and error method. Evaluation and comparison between these methods shows that when using PSO method, the stator active and reactive power ripple can be reduced than the trial and error method. Improvement in the harmonics of the input and output currents of the machine would be one of the other results of using this method.
Regional wave travel and reflections along the human aorta: a study with six simultaneous micromanometric pressures.

The human aorta and its terminal branches were investigated in normal subjects during elective cardiac catheterization to evaluate regional wave travel and arterial wave reflections. A specially designed catheter with six micromanometers equally spaced at 10 cm intervals was positioned with the tip sensor in the distal external iliac artery and the proximal sensor in the aortic arch. Simultaneous pressures were obtained and analyzed for foot-to-foot wave velocity, and Fourier analysis was used to derive apparent phase velocity. These quantities were assessed during control (n = 9), during Valsalva (n = 8) and Müller (n = 4) maneuvers, and during femoral artery occlusion by bilateral manual compression (n = 8). During control, regional cross-sectional areas, determined from aortography, and regional foot-to-foot pulse wave velocities were used to calculate the local reflection coefficient in the proximal descending aorta (gamma = 0.05), at the junction of the renal arteries (gamma = 0.43), and at the terminal aortic bifurcation (gamma = 0.13). To test the hypothesis that significant reflections originate in the aorta, at the level of the renal arteries, aortograms were used to design a latex tube model with geometric properties similar to the descending aorta. Velocities and reflection characteristics in the model and in vivo were compared. Inspection of thoracic aortic pressures under control conditions revealed a reflected wave originating from the region of the aorta at the level of the renal arterial branches while abdominal pressures exhibited reflection from a site peripheral to the terminal aortic bifurcation. In the low frequency range, apparent phase velocity was found to be higher proximal to the renal arteries as compared with at the distal sites. In addition, the minimum value occurred at a higher frequency in the lower thoracic aorta than at more distal sites. The effects of reflection on apparent wave velocity in the tube model were consistent with data obtained in vivo. The Valsalva maneuver diminished the reflection from the aortic region of the renal arteries, thus allowing the distal reflected wave to become more evident on the thoracic pressure waveforms. Bilateral femoral artery occlusion usually enhanced the distal reflection and the Müller maneuver usually resulted in small increases in reflections. In conclusion, the geometric and elastic nonuniformity of the aorta results in two major sites of arterial wave reflection that influence the aortic pressure waveforms in man.

Band based power control (BBPC) for MC-CDMA radio interface

This paper highlights limitations of the ECPC (each carrier power control) concept (S.P.V. Jarot and M. Nakagawa, Proc. IEEE Int. Symp. on Computers and Comms., pp. 331-337, 1999) - originally proposed for OFDM-DS-CDMA - when extended to MC-CDMA (multi-carrier code division multiple access) systems. First, its impractical signaling overhead of 80%; secondly its inability to be used as an uplink power control mechanism. Then we propose BBPC (hand based power control) as a practical alternative to ECPC for MC-CDMA systems. Unlike ECPC that controls power on each carrier basis, BBPC assigns the same power level to a band of carriers (lying within coherence bandwidth of channel). It has been shown that with a nominal performance loss, BBPC reduces the signaling overheads to 2.5% and by employing the control index estimator after de-spreading, it can be used as an uplink power control mechanism for MC-CDMA. We have used SIR (signal to interference ratio) as a power control index, BER and standard deviation of power control error as performance metrics.
Build your own clarithmetic II: Soundness

Clarithmetics are number theories based on computability logic (see this http URL ). Formulas of these theories represent interactive computational problems, and their "truth" is understood as existence of an algorithmic solution. Various complexity constraints on such solutions induce various versions of clarithmetic. The present paper introduces a parameterized/schematic version CLA11(P1,P2,P3,P4). By tuning the three parameters P1,P2,P3 in an essentially mechanical manner, one automatically obtains sound and complete theories with respect to a wide range of target tricomplexity classes, i.e. combinations of time (set by P3), space (set by P2) and so called amplitude (set by P1) complexities. Sound in the sense that every theorem T of the system represents an interactive number-theoretic computational problem with a solution from the given tricomplexity class and, furthermore, such a solution can be automatically extracted from a proof of T. And complete in the sense that every interactive number-theoretic problem with a solution from the given tricomplexity class is represented by some theorem of the system. Furthermore, through tuning the 4th parameter P4, at the cost of sacrificing recursive axiomatizability but not simplicity or elegance, the above extensional completeness can be strengthened to intensional completeness, according to which every formula representing a problem with a solution from the given tricomplexity class is a theorem of the system. This article is published in two parts. The previous Part I has introduced the system and proved its completeness, while the present Part II is devoted to proving soundness.
Effect of the misorientation of the 4H-SiC substrate on the open volume defects in GaN grown by metal-organic chemical vapor deposition

Positron annihilation spectroscopy has been used to study GaN grown by metal-organic chemical vapor deposition on misoriented 4H-SiC substrates. Two kinds of vacancy defects are observed: Ga vacancies and larger vacancy clusters in all the studied layers. In addition to vacancies, positrons annihilate at shallow traps that are likely to be dislocations. The results show that the vacancy concentration increases and the shallow positron trap concentration decreases with the increasing substrate misorientation.
Improvement in holographically formed polymer-dispersed liquid crystal performance through acrylated monomer functionality studies

We investigate the effect of monomer blends on the performance of holographically-formed polymer dispersed liquid crystals (H-PDLCs). Difunctional, trifunctional, and hexafunctional urethane acrylate resins are mixed in different ratios to yield monomers characterized by an effective functionality. Reflection H-PDLCs are formed using the different blends. Reflection efficiency and voltage response are measured. Monomer blends prepared with trifunctional/hexafunctional constituents are formed to yield H-PDLCs with higher reflection efficiency than their difunctional/hexafunctional counterparts, but require higher voltages to switch. Scanning electron microscope investigations are also undertaken.
In Vivo Systematic Analysis of Candida albicans Zn2-Cys6 Transcription Factors Mutants for Mice Organ Colonization

The incidence of fungal infections in immuno-compromised patients increased considerably over the last 30 years. New treatments are therefore needed against pathogenic fungi. With Candida albicans as a model, study of host-fungal pathogen interactions might reveal new sources of therapies. Transcription factors (TF) are of interest since they integrate signals from the host environment and participate in an adapted microbial response. TFs of the Zn2-Cys6 class are specific to fungi and are important regulators of fungal metabolism. This work analyzed the importance of the C. albicans Zn2-Cys6 TF for mice kidney colonization. For this purpose, 77 Zn2-Cys6 TF mutants were screened in a systemic mice model of infection by pools of 10 mutants. We developed a simple barcoding strategy to specifically detect each mutant DNA from mice kidney by quantitative PCR. Among the 77 TF mutant strains tested, eight showed a decreased colonization including mutants for orf19.3405, orf19.255, orf19.5133, RGT1, UGA3, orf19.6182, SEF1 and orf19.2646, and four an increased colonization including mutants for orf19.4166, ZFU2, orf19.1685 and UPC2 as compared to the isogenic wild type strain. Our approach was validated by comparable results obtained with the same animal model using a single mutant and the revertant for an ORF (orf19.2646) with still unknown functions. In an attempt to identify putative involvement of such TFs in already known C. albicans virulence mechanisms, we determined their in vitro susceptibility to pH, heat and oxidative stresses, as well as ability to produce hyphae and invade agar. A poor correlation was found between in vitro and in vivo assays, thus suggesting that TFs needed for mice kidney colonization may involve still unknown mechanisms. This large-scale analysis of mice organ colonization by C. albicans can now be extended to other mutant libraries since our in vivo screening strategy can be adapted to any preexisting mutants.
Flashlight Scene Detection for MPEG Videos

A new flashlight scene detection approach is presented. It focuses on two techniques: a new flashlight model based on the spatial-temporal characteristics of intensity value for the DC sequence, and a local threshold selection scheme using the sliding window. The advantages of this approach are its good performance for multi-frame and gradual flashlight scene cases, and local threshold selection. Experimental results show that the proposed algorithm is fast, robust and high accuracy
Paramyxovirus Glycoprotein Incorporation, Assembly and Budding: A Three Way Dance for Infectious Particle Production

Paramyxoviruses are a family of negative sense RNA viruses whose members cause serious diseases in humans, such as measles virus, mumps virus and respiratory syncytial virus; and in animals, such as Newcastle disease virus and rinderpest virus. Paramyxovirus particles form by assembly of the viral matrix protein, the ribonucleoprotein complex and the surface glycoproteins at the plasma membrane of infected cells and subsequent viral budding. Two major glycoproteins expressed on the viral envelope, the attachment protein and the fusion protein, promote attachment of the virus to host cells and subsequent virus-cell membrane fusion. Incorporation of the surface glycoproteins into infectious progeny particles requires coordinated interplay between the three viral structural components, driven primarily by the matrix protein. In this review, we discuss recent progress in understanding the contributions of the matrix protein and glycoproteins in driving paramyxovirus assembly and budding while focusing on the viral protein interactions underlying this process and the intracellular trafficking pathways for targeting viral components to assembly sites. Differences in the mechanisms of particle production among the different family members will be highlighted throughout.
A case study of LEGO Mindstorms'#8482; suitability for artificial intelligence and robotics courses at the college level

This paper examines LEGO Mindstorms'#8482; suitability as a hardware platform for integrating robotics into an Artificial Intelligence course organized around the agent paradigm popularized by Russell and Norvig. This evaluation discusses how kits and projects based on Mindstorms supported students' exploration of the issues behind the design of agents from three classes in Russell and Norvig's intelligent agent taxonomy. The paper's investigation also examines several popularly-perceived limitations of the Mindstorms package for college-level robotics projects and shows that most of these "limitations" are not serious impediments to Mindstorms' use, while certain other of these "limitations" do indeed present challenges to the platform's use.
Quetiapine Versus Placebo in Combination With Lithium or Divalproex for the Treatment of Bipolar Mania

Abstract: Quetiapine (QTP) combined with lithium (Li) or divalproex (DVP) for the treatment of mania was evaluated in 2 double-blind, placebo-controlled studies. Patients were randomized to 3 or 6 weeks of treatment with QTP plus Li/DVP or placebo (PBO) plus Li/DVP. Quetiapine was dosed up to 800 mg/d; Li was dosed to achieve serum concentrations of 0.7-1.0 mEq/L and DVP to 50-100 μg/mL. A total of 402 patients were randomized: 197 to QTP + Li/DVP and 205 to PBO + Li/DVP. The mean quetiapine dose in responders was 492 (±204) mg/d. Improvement in the Young Mania Rating Scale (YMRS) at day 21 in the QTP + Li/DVP group (−15.29) was statistically superior to the PBO + Li/DVP group (−12.19) (P < 0.05). A statistically significant difference in favor of quetiapine was observed within the first week (P < 0.05). Significantly more QTP + Li/DVP patients achieved a response (≥50% decrease in the YMRS) at day 21 (QTP + Li/DVP, 55.7%; PBO + Li/DVP, 41.6%;P < 0.01). Improvements in Clinical Global Impression-Bipolar Severity of Illness scores by day 21 were also significantly greater in QTP + Li/DVP-treated patients (−1.59) versus PBO + Li/DVP (−1.19) (P < 0.01). Common adverse events (≥5% and twice that in the PBO + Li/DVP group) in the QTP + Li/DVP group were somnolence, dry mouth, and asthenia. Quetiapine combined with Li/DVP was not associated with extrapyramidal symptoms (including akathisia) or emergent depression. More QTP + Li/DVP-treated patients completed the trial, and there was no difference in discontinuation rates due to adverse events between the two groups. Quetiapine, in combination with lithium or divalproex, is well tolerated and has superior efficacy to lithium or divalproex alone in the treatment of bipolar mania.
