Agrobacterium tumefaciens is a kind of Gram-negative soil bacterium, which harbors tumor inducing(Ti) or root inducing(Ri) plasmid. The T-DNA on the plasmid can enter plant cells and integrate into the host genome, and further endows plants new characteristics by stable inheritance. Thus, Agrobacterium tumefaciens, as a most efficient transformation vehicle, has been widely used in genetic engineering study for most dicotyledonous and part of monocotyledonous plants. Agrobacterium-mediated transformation technology has several advantages including simple process, low cost, less gene silence, and few copies of target genes. However, the transferring of target genes into plant genome by Agrobacterium is a complicated biological process, during which a lot of Agrobacterium proteins and plant proteins interact with each other for the mission of importation, transportation and integration of T-DNA. Associated host proteins play important roles almost in each step of the transformation of exogenous genes. For instance, AGPs, rhicadhesin binding protein, and vitronectin-like protein are involved in the Agrobacterium attachment to the surface of plant cells; GTPase and BTI proteins help T-DNA and Vir proteins enter plant cell; Actin, GIP, and VIP assist T-DNA transportation in plant protoplasm; VIP1, KAPa, PP2C, and Roc participate in the targeting and importing of T-DNA complex to plant cell nuclear, histones; VIP1 and VIP2 perform functions on the integration of T-DNA into plant genome. Due to the huge differences between plants in genomics, physiology and biochemistry, overexpression of some plant genes mentioned above do improve the transformation frequency in some plants mediated by Agrobacterium, while that doesn't work in other plants. It was indicated that VIP1, VIP2, AGP and H2A are closely associated with the Agrobacterium-mediated transformation efficiency of some model plants like Arabidopsis and rice. However, the functions of these proteins in some recalcitrant plants to Agrobacterium infection such as wheat and maize are still undetermined. Thus, some novel proteins or genes associated with T-DNA transformation need to be isolated and identified in different plants. Presently, there are two marked features in the Agrobacterium-mediated transformation of plants. One is that the transformation technology of Agrobacterium-mediated for model plant species such as tobacco, Arabidopsis and rice is almost reaching a perfect level, and another one is that the technique is still difficult to be applied in some economically important crops including wheat, maize and soybean. Therefore, it is necessary to further investigate the roles of plant proteins associated with the transformation network in more plants. In this article, the plant proteins related to Agrobacterium infection and T-DNA delivery reported to date are reviewed to provide some useful information for the improvement of Agrobacerium-mediated transformation efficiency for some recalcitrant plants to be transformed.


JK wall is a shear wall made of lightweight EPS mortar and reinforced with a 3-D galvanized steel mesh, called JK panel, and truss-like stiffeners, called JK stiffeners. Earlier studies have shown that low strength lightweight concrete has the potential to be used in structural elements. In this study, seismic contribution of the JK infill walls surrounded by steel frames is numerically investigated. Adopting a hybrid numerical model, behavior envelop of the wall is derived from the general purpose finite element software, Abaqus. Obtained backbone would be implemented in the professional analytical software, SAP2000, in which through calibrated hysteretic parameters, cyclic behavior of the JK infill can be simulated. Through comparison with earlier experimental results, it turned out that the proposed hybrid modeling can simulate monotonic and cyclic behavior of JK walls with good accuracy. JK infills have a panel-type configuration which their dominant failure mode would be ductile in flexure. Finally technical and economical advantages of the proposed JK infills are assessed for two representative multistory buildings. It is revealed that JK infills can reduce maximum inter-story drifts as well as residual drifts at the expense of minor increase in the developed base shear.

This article argues that ancient Chinese Philosophy-Aesthetics, as an important Other from the West, has made global contributions which are of major significance to the future theoretical building. Most Western scholars and some modern Chinese scholars so far have failed to pay attention to these critical achievements. This article intends to expound the global contributions of Chinese aesthetics in three ways. One is Laozi's interpretative mode of grandeur, another is Zhuangzi's notion of mutual generative aesthetics and the other Mencius's view of philosophical beauty.


Methanotrophs can oxidize methane to carbon dioxide through sequential reactions catalyzed by a series of enzymes including methane monooxygenase, methanol dehydrogenase, formaldehyde dehydrogenase, and formate dehydrogenase. Reducing carbon dioxide to methanol is an opposite reaction of methanol oxidation, which requires a considerable amount of energy. So far there are no known organisms whose normal biological role is reduction of carbon dioxide to methanol. In this communication, we report that bioconversion of carbon dioxide to methanol was successfully achieved using resting cells of methanotrophic bacteria of Methylosinus trichosporium IMV 3011 as biocatalysts. Extracellular methanol accumulation has been found in the carbon dioxide incubations. The conversion of carbon dioxide to methanol is energy-intensive and requires reducing equivalent to push the reaction along against energy laws. For long-term maintenance of methanol synthesis, methane was selected as a substrate for regeneration of reducing equivalent. By alternate reaction and regeneration, the results show that resting cell of M. trichosporium IMV 3011 can be used for many times to catalyze the reduction of carbon dioxide, in which the origin of the reducing equivalent is methane. It is possible to theoretically deduce that the overall reaction for methanol synthesis can be completed by biocatalysis using greenhouse gases (carbon dioxide and methane) as raw materials without adding hydrogen. This new route should be environmentally friendly and a selective process operating at room temperature and normal pressure. Also, it is theoretically possible that the overall reaction can produce methanol without adding to the greenhouse effect.

The magnesium alloy investment castings have greater potential for automobile and air-craft applications due to the higher strength to weight ratio of magnesium alloys and capability of the investment casting process to produce near net shape complex castings. The interfacial-mould metal reactions during investment casting of magnesium alloy inhibit successful production of quality castings. This paper presents the investigation done on the reactions at corners of AZ91 magnesium alloy cast part produced through investment casting. The stepped shape geometry of casting was selected to study the reactions at convex and concave corners of the cast part. The reacted surfaces were characterised using the SEM-EDX and XRD. The formation of oxides was observed on cast surface from characterisation. The temperature profile recorded at corners were helpful to understand the heat dissipation during the solidification of metal at corners. It was observed that the reactions occurred at the concave corner were more as compared to the convex corner of the cast part.


The influence of cracking on durability of concrete components with reinforcing bar is greater in the case of chloric ion corrosion and the durability of these components can be improved by means of active and effective control over their cracking.The rustiness amount and rate of the reinforcing steel with carbon fiber constraint were theoretically analyzed and explored for the case of longitudinal cracking of the protection layer on the concrete components and the propagation pattern of concrete component cracking was discussed,also.The model of elastic mechanics for the destruction of the protection layer due to expansive cracking was revised and a evaluation model of rustiness amount of reinforcing steel with carbon fiber constraint was set up for the case of expansive cracking of protection layer.The result verified that a reasonable way of carbon fiber reinforcement could effectively constrain the propagation of longitudinal crack in concrete components.

IN RESPONSE to a dramatically rising concern among federal policy makers concerning our national performance in delivering human services, Evaluation magazine dedicated a special issue ( 1974) to the frustrating problem of the shortfall in human services. American leaders Jimmy Carter, Amitai Etzioni, Henry Ford, II, Walter Heller, Elliot Richardson, James Tobin, Martha Gri~ths, among others deplored the disappointed hopes of millions of suffering people who were intended to be, but who were not, rescued by vast human service programs. Not always was or is cost the culprit. The resistances to the policies established, inefficient administrative systems, changing circumstances and time itself all played a part. But the conclusion of Lynn (1974) is compelling: &dquo;Our only realistic hope, as far as a strategy is concerned, lies in ... doing the hard work of researching, evaluating, experimenting, advocating, and negotiating, but doing it as well and as thoroughly as we can&dquo; (p. 43) (italics ours) . Social research can indeed serve as a combatant against policy failure, waste, and the consequent unmet needs. For the myriad shortfalls of social policy at local, national and international levels, social research has significant help to offer in rendering murky waters clearer to allow accurate analysis.

ABSTRACT In this work, three-dimensional (3D) printing system based on fused deposition modeling (FDM) is used for the fabrication of conductive polymer nanocomposites. This technology consists in the additive multilayer deposition of polymeric nanocomposite based on poly(lactic acid) (PLA) and graphene by means of a in house made low-cost commercial bench-top 3D printer. Further, 3D printed PLA/graphene nanocomposites containing 10 wt% graphene in PLA matrix were characterized for their mechanical, electrical and electromagnetic induction shielding properties of the nanocomposite. Furthermore X-ray computed micro-tomography analyses showed that printed samples have good dimensional accuracy and are significantly closer to the predefined design and the results of scanning electron microscopy (SEM) printed samples showed a uniform dispersion of graphene in PLA matrix The proposed material has uniquely advantageous when implemented in 3D printed structures, because incorporation of multifunctional graphene has been shown to substantially improve the properties of the resulting nanocomposite.

This system is making a great contribution to the traffic safety and smoothness by using its advanced signal control technology.


Owing to the fact that the reliability of line regression analysis method of statistical analysis is not high, the fuzzy linear regression method is put forward, but there is a default in the classical fuzzy linear progression analysis, that is, its value will become more and more fuzzy with the extension of the independent variables. This paper reveals the default based on the fuzzy structured element, and overcomes this default through using the fuzzy function to fit the data, here we have fuzzy structured element describe the fuzzy function. Theory proves that it is a kind of effective fuzzy regression analysis method, and gains good effect by example.


In spray dryer flue gas desulfurization, lime slurry is injected into a spray dryer where it contacts with the hot flue gas and desulfurization occurs. This process is complex owing to the heat and mass transfer which must take place. One of the most important fundamental steps in the scrubbing process is the rate at which lime dissolves from the solid particle in the slurry drop and becomes available for reaction with the absorbed sulfur dioxide. This dissolution rate to a large extent controls the degree of reactivity and is the rate controlling step for this process. However, studies on this dissolution rate have been very few and its magnitude under a variety of operating conditions is not well known. This research has as its objective, the study and understanding of the lime dissolution rate. This understanding should lead to a better method of predicting and optimizing spray dryer performance for flue gas desulfurization.

In this study, an alternative approach was applied for the characterization of the subsurface geological conditions to estimate the hydrological parameters in the absence of subsurface soil data. The study revealed that the hydrological parameters, estimated from the Transient Electromagnetic (TEM) and Electrical Resistivity Tomography (ERT), were significantly correlated with in situ data. Overall estimated infiltration rate (below 20 inches/h) predicted fine-grained soil was also associated with in situ data. A high correlation among the bulk electrical resistivity, porosity, and the resistivity of the pore fluid thereby confirmed the relevance of Archie's law used in this study. Furthermore, results showed that both TEM and ERT are vital tools for hydrological parameter estimation.

Field-theoretical methods have been shown to be useful in constructing simple effective theories for two-dimensional (2D) systems. These effective theories are usually studied by perturbing around a mean-field approximation, so the question whether such an approximation is meaningful arises immediately. We here study 2D interacting electrons in a half-filled Landau level mapped onto interacting hard-core bosons in a magnetic field. We argue that an interacting hard-core boson system in a uniform external field such that there is one flux quantum per particle (unit filling) exhibits an integer quantum Hall effect. As a consequence, the mean-field approximation for mapping electrons at half-filling to a boson system at integer filling fails.


The dynamic of a micro-grid consisting of an engine generator and sixteen fuel cells was clarified by the transfer function model using actual data from power generators. The micro-grid was composed of a 3kW engine generator and 1kW fuel cells, and the dynamic characteristics of the grid were analyzed using the energy demand model in February of a cold region. Consequently, the settling time (Time taken to converge on ±5% of the limit of an output target) of a micro-grid is 15 seconds from 10 seconds. The control parameter of a fuel cell system is significantly influenced by the settling time and overshooting of a micro-grid. Since any excess and deficiency in electric power can respectively be covered if two or more fuel cells are connected with a grid, the instant electric power demand load peak can be distributed. Compared with the number of fuel cells required when installing independently, the number of installations can be reduced for a micro-grid system.

We consider the Graham–Knuth–Patashnik recurrence, namely T (n, k) = (αn+ βk + γ)T (n− 1, k) + (α′n+ β′k + γ′)T (n− 1, k − 1) (1.1) for n > 1, with initial condition T (0, k) = δk0. For each choice of the parameters μ = (α, β, γ, α′, β′, γ′), we obtain a unique solution T (n, k) = T (n, k;μ), forming a triangular array T (μ) = ( T (n, k;μ) ) 06k6n . Given a triangular array T = ( T (n, k) ) 06k6n , we define its row-generating polynomials


The increasing demand on high bit rate and reliable wireless and wire line system has junction rectifier to several new rising modulation techniques. one among the techniques are going to be Orthogonal Frequency Division Multiplexing (OFDM), that offers reliable high bit rate wireless system with cheap complexness. the first reasons OFDM is most popular in most high information measure potency transmission systems ar as a result of it effectively resist Inter Symbol Interference (ISI) and is powerful towards multipath weakening. Orthogonal Frequency Division Multiplexing (OFDM) could be a digital transmission methodology developed to satisfy the increasing demand for higher knowledge rates in communications which might be utilized in each wired and wireless environments. This thesis describes the problem of the height to Average Power magnitude relation (PAPR) in OFDM that could be a major downside, and presents new and variations to existing algorithms to cut back it.


Dimpled steel products are produced from the combination of an innovative dimpling process and a traditional forming process such as cold-roll forming or press-braking. The wider use of cold-formed dimpled steel members has promoted considerable interest in the local instability and strength of these members. Of particular interest is their buckling behaviour and ultimate strength capacity. However, the dimpling process produces cold-formed sections with a complex 'dimpled' surface topography and the 'dimpled' material is non-uniformly work hardened through the entire thickness. Owing to these complex issues, there are no existing methods to calculate the buckling strength of the dimpled products and validate against physical measurements. This paper presents a Finite Element analysis of the compressive behaviour of cold-formed dimpled steel columns. True stress-strain data obtained from physical tests were incorporated into nonlinear simulations of dimpled steel columns. The simulation results were compared with compression test results on dimpled channel and lipped channel columns and good agreements in both buckling and ultimate strength were obtained. It is demonstrated that the Finite Element analysis can therefore be used to analyse and design cold-formed dimpled steel columns.


The Personal Sphere Model, a projective instrument developed to elicit a representation of the object-relation world of an individual and previously used with clinical populations, was administered to 310 college students. Norms were developed and component factors extracted. Seven major factors—productivity, number of family, number of ideas, number of things, number of interruptions in relationships, size of objects, and number of bonds—accounted for 86% of the variance. Criterion validity was established as the representation of interruptions was significantly correlated with scores on the Beck Depression Scale and the Rotter Internal-External Locus of Control Scale.


This study examines the similarities between the current crisis and other systemic crises from the past. The purpose of our research is to discover whether previously used crisis management policies can constitute a referential in choosing the most effective policies for the management of the current crisis. This study highlights important similarities between the current crisis and those that occurred in the past in Norway (1991) and Japan (1997), using a cluster analysis in order to obtain homogeneous groups of crises.. Also, through a qualitative analysis of crisis management policies, the study stresses the need to learn from past lessons.

We studied the composition of terrestrial amphibian, reptile, and small mammal assemblages in five types of forested habitats in Prince William Forest Park (PWFP) in northern Virginia ranging from hydric to xeric moisture regimes. We used drift fences and pitfall traps to capture 1,099 individuals representing seven species of anurans, seven salamanders, three lizards, four snakes, four shrews, and four rodents. The wetter floodplain and mesic sites supported significantly higher numbers of amphibians than the three drier sites (mixed, oak, pine). Numbers of Plestiodon fasciatus, the only reptile captured in abundance, were not significantly different among all five sites. Number of captures of three species of mammalian insectivores documented at all five sites did not differ significantly. No rodent species was abundant on these sites, although more Peromyscus leucopus were captured than other species; it occurred most often in the mesic site. The pine (xeric) site had the fewest species and the lowest number of individuals of all the vertebrate groups. The regenerated forest in PWFP should allow long-term persistence of the herpetofauna and small mammals characteristic of this region.


Dear Editor, As pointed out by Pajoumand et al. [1], intoxication with benzodiazepines in general has a low mortality and we agree that every recommendation on benzodiazepine treatment strategies and patient management in intoxicated patients should be given with caution. With regard to the population included in our meta-analysis [2], we disagree that only patients with a pure (single-drug) intoxication were eligible to be compared with the placebo group. Multidrug intoxications of benzodiazepines combined with ethanol, anxiolytics (including barbiturates), opioids and tricyclic antidepressants are common in the emergency rooms and might be more common than single-drug intoxications (illustrated by the higher frequency observed also in our study). Thus, by including this group of patients in our meta-analysis, the study resembles 'real-life' situations. Hospitalization period, need of intubation, and/or intensive care admission as well as long-term adverse events and total costs are indeed relevant parameters to be included in future studies. Unfortunately, all studies included in our meta-analysis had only short observation time before unblinding of treatment. This is probably because flumazenil (initially) was considered a pure antidote without intrinsic effects (including adverse effects), and by some investigators, it was perceived unethical to withhold flumazenil treatment. In more than half (9 of 13) of the studies included in our meta-analysis [2], the blinded treatment period was followed by a second phase with the possibility of open-label treatment with flumazenil to both the primary flumazenil-treated group and the placebo group. Therefore, evaluation of hospitalization period, need of intubation, and/or intensive care admission as well as long-term adverse events and total hospitalization costs was not possible in the present meta-analysis [2]. The study by Barnett et al. [3] from 1999 investigated the cost-effectiveness of flumazenil administration to patients presenting with suspected acute drug overdose. Forty-one patients (19 flumazenil, 22 placebo) were included in the study, which concluded that 'the empirical use of flumazenil in patients with intentional drug overdose is not cost-effective. Future studies in this area should be directed to identifying those patients who would most benefit from specific drug antagonist treatment, as this information may improve the cost-effectiveness of such therapy'. To the authors' knowledge, such studies have not been reported. Thus, we still believe that every case with flumazenil (co-)intoxication must be considered at individual basis with a careful evaluation of benefits and harms, including the knowledge of (the risk of) contraindications for and the risk of adverse reactions associated with flumazenil administration. As concluded in our meta-analysis, a large, randomized, placebo-controlled trial with a sufficient observation time to observe later-occurring adverse events is welcomed.


In a rare public action, the human rights committees of the National Academy of Sciences and the Institute of Medicine have called on Somalia to free 13 scientists, engineers, and physicians who have been "unjustly imprisoned for more than five years" for alleged anti-government statements or acts. The committees also have urged the president of Somalia, Mohamed Siad Barre, to end what they call frequent torture and mistreatment of hundreds of political prisoners, including the 13 cases. These pleas are made in a 97-page report just given to the Somali ambassador to the U.S. by a four-member delegation that visited Somalia's capital, Mogadishu, last October. Members were Francisco J. Ayala, professor of biological sciences, University of California, Irvine; Carol Corillon, director of the NAS and IOM human rights committees; M. Alfred Haynes, former president and dean, Charles R. Drew Postgraduate Medical School, Los Angeles; and Nobel Laureate Lawrence R. Klein, professor of economics and finance, ...


Advanced High-strength steels (AHSS) has widely application in automotive due to their high tensile strength and remarkable ductility. These good mechanical performances are strongly influenced by the processing and final microstructure. This paper performed Deformation Dilatometer and finite element simulation to study the effect of hot rolling parameters such as strain, cooling rate, and holding time at constant temperature on the microstructure formation of Nb-V low carbon microalloyed steel grade. It found that increasing deformation degree increased the volume fraction of ferrite, both of deformation dilatometer and finite element simulation give a similar trend of effects of hot rolling parameters on evolution of volume fraction of ferrite. These results give an insight for industrial application.

As the chemical industry seeks more sustainable processes, many researchers believe that using plants as an alternative source of chemicals could help curb carbon dioxide emissions and reduce the world's dependence on oil and gas. To become economically viable, the biorefineries producing these renewable chemicals will need to squeeze as much value as possible from plants. But plant matter can be frustratingly intractable, with components, like lignin, that are difficult to convert into useful molecules. Researchers in Belgium have now developed an integrated series of chemical processes that can break down lignin and turn 78% of the mass of birch wood into chemical products including phenol, propylene, and ethanol (Science 2020, DOI: 10.1126/science.aau1567). The team, led by Bert F. Sels at KU Leuven, has demonstrated the method at lab scale, and its calculations suggest that a full-scale biorefinery would have a much lower carbon footprint than fossil-based production systems while

ABSTRACT Impact of European Cohesion Policy on regional growth: does local economic structure matter? Regional Studies. A growing body of literature has analysed the effect of European Cohesion Policy on regional gross domestic product (GDP) growth. The paper contributes to this literature by discussing Structural Funds and assigning an explicit role to the choice of strategy and the economic structure of regions. In particular, adopting a regression discontinuity design with heterogeneous treatment and using data on NUTS-3 regions makes it possible to identify the causal impact of Structural Funds on regional growth according to the size of the service sector, a sector that accounts for a large share of total Structural Funds expenditure. The paper shows that the larger the sector, the greater the amount of financial resources directed to services and the slower is growth. The interpretation pertaining to policy implications is that higher growth rates can be obtained by promoting the service sector at its early stages, i.e., when it is comparatively small and its potential for productivity growth is higher.


This work describes the experimental characterization of a commercial sodium–nickel chloride battery and the investigation on a state-of-the-art model that represents the battery behavior. This battery technology is considered very promising but it has not fully been exploited yet. Besides improvements on the technological side, accurate models of the battery should be found to allow the realization of Battery Management Systems with advanced functions. This achievement may extend the battery exploitation to its best. The paper describes the experimental set-up and the model parameter identification process, and discusses the identified parameters and the model validation tests. The comparison between model simulations and experiments shows that the model is rather accurate for low-current rates, but it loses accuracy and it is not able to reproduce with fidelity the battery behavior at low states of charge or at high current rates. Further research efforts and refinements of the model are necessary to make available a sodium–nickel chloride battery model accurate in any operating condition.


In order to improve the detonation performance of the explosive network on the basis of achieving high safety and reliable detonation, 3,4-dinitrofurazanyl oxyfurazan (DNTF) was used as the main explosive, glycidyl azide polymer(GAP) was used as the binder, and other auxiliary agents were added to the basic charge formula. Then, polytetrafluoroethylene (PTFE) and aluminum (Al) were introduced to further enhance the output power of the charge formula. The influence of two introduction methods of PTFE and Al was evaluated: directly mechanically mixing method and activation method by metal ball milling. A variety of tests such as particle size, morphology, detonation performance in groove were carried out to study the difference between mixed Al/PTFE and milling activated Al/PTFE. The experiment showed that particle size becomes smaller and Al/PTFE were well compounded. Moreover, results showed that the charge formula with milling activated Al/PTFE possessed good propagation reliability in micro linear groove and stronger external expansion capability. These properties were vital for the charge formula to be applied to the complex explosive circuits used for micro shaped charge warhead.

Language is an important carrier and also an important part of the culture.Foreign language communicative ability is closely related with the social and cultural factors and under the influence and constraints of them.Traditionally,teaching Chinese as a second language just focuses on teaching Chinese language knowledge to foreign students.We emphasizes making grammatical sentences while ignoring the communicative skills of foreign students.When overseas students communicate with others using Chinese,the ways of thinking and cultural differences may lead to misunderstanding or communication failure,which requires teachers to have a considerable understanding of the cultural connation of our Chinese language and take the initiative to teach students to make sure that they can use the language correctly in a variety of different situations.This particle begins with the relationship between the traditional culture and national language and finds out the cultural factors from the infiltration of characters,idioms and classical poetry to Chinese teaching,in order to promote the reform and deepining of Chinese teaching.

Firstly,this paper introduces the current mode of project management in the world.Then it analyses their advantages and disadvantages of different aspects.It also suggests that the investor of a construction project should contract with socialized and specialized project management companies to manage the project.


Supply chain is an advanced management mode in enterprise management,which can achieve double win on every knots in supply chain.As the supplier is the headstream of the whole supply chain,it is supplier selection that determines the advantage of improvement in enterprise competition.The paper discusses and investigates the method in selecting supplier in the qualitative and quantitative terms,analyzes advantages and disadvantages of various kinds of methods and how to choose the suitable one,thus favorable for choosing the supplier for enterprises.


A high prevalence of sleep disorders has been reported in patients affected by type III mucopolysaccharidosis (Sanfilippo syndrome). These disorders include an extremely irregular sleep pattern, with several sleep episodes of inconsistent duration which are irregularly distributed over the 24 hr; at its onset, the condition might appear as a disorder of initiating or maintaining sleep [1]. For that reason, rather than conventional hypnotic therapies aimed at circadian resynchronization such as behavioural treatment, light therapy or melatonin administration has been suggested. A recent study by Fraser et al. [2] surveyed clinicians with particular expertise in the management of individuals with mucopolysaccharidosis and they reported that melatonin would be the medication most likely to be of benefit [2]. Whether circadian melatonin production is affected in these patients has not been tested. In the present study, we compared the circadian urinary excretion of 6-sulfatoxymelatonin (6S-Mel) in children diagnosed with Sanfilippo syndrome with that of controls. Sanfilippo syndrome patients (n 1⁄4 12; eight female and four male) and healthy volunteers (n 1⁄4 9; five female and four male) were between 6 and 14 yr of age. Urine samples were collected at the times indicated in Fig. 1 over a 24-hr period and frozen at )30 C until used for 6S-Mel and creatinine determinations. Final results are expressed as nanogram 6S-Mel per microgram creatinine. 6S-Mel was determined by enzyme-linked immunosorbent assay (Immuno Biological Laboratories, Hamburg, Germany). Blood samples were also obtained at 09:00 hr to isolate peripheral blood mononuclear cells (PBMCs) which were used for expression of N-acetyltransferase (NAT) and hydroxyindole-O-methyltransferase (HIOMT) mRNA studies. mRNA isolation from PBMCs, single-stranded cDNA synthesis, and polymerase chain reaction amplifications were performed as described previously [3, 4]. As shown in Fig. 1, there is a significant difference in the circadian excretion of urinary 6S-Mel in Sanfilippo syndrome patients when compared with controls. Sanfilippo syndrome patients exhibited lower concentrations of urin-


Undoped and Cu doped SnO2 thin films were fabricated by sol‐gel method. The influence of annealing temperature, Cu doping and the addition of polyethyleneglycol (PEG)/glycerine on the film crystallinity, morphology and electrical properties were investigated. It is shown that annealing temperature can affect the film crystallization by controlling the crystallinity of the film and adhesion between the substrate and the films. Besides, both the Cu doping and PEG/glycerine addition can reduce the cracks quantity on the film. Cu doping can form Cu: SnO2 solid solution which depress the onset of cracks. PEG/glycerine can increase the viscosity of solution which reduces the film drying speed, and thus provides more time for grain recombination and stress release. The conductivity of both the Cu: SnO2 film and films added with PEG/glycerine improved comparing with pure SnO2 film, which can be explained by the formation of oxygen vacancies induced by the Cu substitutional doping and the reduced amounts of cracks due to the additive of PEG/glycerine, respectively. This work may provide some useful information to optimize the SnO2 gas‐sensing devices.


ANALYSIS: The concept of focusing on bottlenecks -pressure points where a process is held up by incapacity or inefficiency has been applied in business, logistics and economics. It is consistent with formal orthodox economic models and is also being applied to development policy. 'Binding constraint' is standard economics parlance, but a group of distinguished economists at Harvard University advances the use of what they call a 'diagnostics approach' to identifying the bottlenecks to economic growth on a case-by-case basis. Perhaps the most instructive aspect of this approach is what it is not: it is not a laundry list of problems and desires. Targeting limited resources -financial or administrative -at key problems is the rationale for the diagnostics approach.

For the past years, Catholic people have been getting along well with the rest people of the country. Based on the viewpoint of "living for better life and better religion", they actively participated in emulation movements. They carried out a lot of practical and effective activities, according to the idea of "traveling together with the nation and devoting life to happiness of the people" among Catholic communities in Vietnam. The paper outlines some contributions of Catholic people in the socio-cultural area such as:  social charity activities (including contributions in healthcare, education and others), cultural life building and social evil prevention, which have been conducted in our country for the past time. Recognizable achievements in the socio-cultural area show that Catholic people in Vietnam have contributed a significant part into building, defending and developing the country. At the same time, it is a clear evidence to illustrate the roles and responsibilities of Catholic people in conducting the "God-fearing and patriotic Catholic" movement and following the Common letter of Vietnamese Bishop Committee that advises Catholic people "to have a strong attachment to the nation and country... and to live evangelically inside the nation".


Lupus nephritis (LN) is the most common severe manifestation of systemic lupus erythematosus (SLE), occurring in up to 40% of patients (pts) with SLE over their disease course, and resulting in 10–20% of pts progressing to end-stage kidney disease.1-3 The BLISS-LN (GSK Study BEL114054; NCT01639339) study demonstrated that the addition of intravenous (IV) belimumab (BEL) to standard therapy (ST) in pts with active LN significantly improved renal responses over 2 years compared with ST alone.4 Here we present additional safety and efficacy data from the 6-month open-label (OL) extension phase of BLISS-LN.

 In this OL phase, eligible completers of the Phase 3 BLISS-LN study (those who received BEL or placebo [PBO] through Week 100 and completed Week 104 assessments) received BEL 10 mg/kg IV plus ST every 28 days for 24 weeks. Endpoints at OL Week 28 included: safety; Primary Efficacy Renal Response (PERR; defined as urine protein:creatinine ratio [uPCR] ≤0.7; eGFR no more than 20% below OL baseline value or ≥60 ml/min/1.73m2; no rescue therapy); Complete Renal Response (CRR; defined as uPCR <0.5; eGFR no more than 10% below OL baseline value or ≥90 ml/min/1.73m2; no rescue therapy); uPCR; eGFR; the proportion of pts with Systemic Lupus Erythematosus Disease Activity Index (SLEDAI) score <4; Systemic Lupus International Collaborating Clinics/American College of Rheumatology Damage Index (SDI); and corticosteroid use. Analyses were based on observed data and summarised relative to the OL baseline (last available value measured prior to dosing on or before the date of the first OL treatment dose).

 Of 257 pts (57.4 % of pts in BLISS-LN double-blind [DB] study) screened and enrolled, 255 pts were treated (safety population: 123 pts switched from PBO to BEL; 132 pts remained on BEL). In total, 254 pts were included in the efficacy analyses (PBO to BEL: 122 pts; BEL to BEL: 132 pts). Mean (standard deviation) age was 35.9 (10.3) years.
 In total, 3.5% of pts withdrew from the OL phase, mainly due to adverse events (AE; 2.0%). Overall, 168/255 (65.9%) pts experienced ≥1 AE (76/123 [61.8%] PBO to BEL pts; 92/132 [69.7%] BEL to BEL pts); 49/255 (19.2%) pts had ≥1 treatment-related AE (25/123 [20.3%] PBO to BEL pts; 24/132 [18.2% ] BEL to BEL pts); 15/255 (5.9%) pts had ≥1 serious AE (5/123 [4.1%] PBO to BEL pts; 10/132 [7.6%] BEL to BEL pts); and 1 death was reported in the PBO to BEL group.
 The proportion of patients achieving PERR and CRR increased from OL baseline to OL Week 28 in both groups (Table). The median (interquartile range [IQR]) for uPCR and eGFR were maintained from OL baseline through to OL Week 28 (Table).
 The proportion of SLEDAI score <4 responders in BEL to BEL group tended to increase from OL baseline to OL Week 28, and decrease in the PBO to BEL group (Table). SDI worsening (change >0) was experienced by 7 (2.9%) pts (4 [3.3%] PBO to BEL; 3 [2.5%] BEL to BEL) compared with OL baseline.
 There was no appreciable change in the number of patients receiving average daily prednisone-equivalent doses of ≤5 mg or ≤7.5 mg from OL baseline to OL Week 28 (Table).

 BEL was well tolerated as an add-on to ST, with no new safety signals. Efficacy among pts with LN randomised to BEL during the DB phase was maintained during the OL phase.

Pronounce the pledge of talak has a very important position in the divorce petition filed by a husband against his wife in the Religious Court. When a husband does not make a pledge of divorce for reasons of reconciliation with his wife then it is very good for their marital relationship. But when a husband does not pronounce the pledge of talak for reasons of slowing down and stalling the time for divorce does not occur so the pledge of divorce slips and his marital bond remains intact. This phenomenon is the cause of legal uncertainty and there is no sense of justice for the wife. The purpose of this research is to (1) know and analyze the arrangement of the cancellation of pronunciation of ikrar talak in the religious court (2) to know and analyze how the legal effect on the cancellation of pledge of pledge of talak in religious court with normative juridical method. The results of this study indicate that (1) the arrangement of cancellation of pronouncement of pledge of talak in religious court has been regulated in Article 131 Compilation of Islamic Law but not set in detail administrative sanction given to husband when husband did not pledge for reasons of stalling the time of divorce and (2) the legal consequences of the cancellation of the pledge of the vow of talak in religious court may result in legal uncertainty and injustice for the wife due to the absence of a divorce so that the household ties remain intact and there is no sanction for the husband. The benefits of this research are to contribute in the form of empirical thoughts and findings, especially regarding the practice of pledge of talak in religious courts.


In this paper we introduce a family of numerical approximations for the stochastic differential equations (SDEs) with no globally Lipschitz coefficients. We show that for a given Lyapunov function V : R → [1,∞) we can construct a suitably tamed Euler scheme that has so called V-stability property of the original SDEs. V-stability condition plays a crucial role in numerous stability and integrability results for SDEs developed by Khasminski [6]. These results can be recovered by tamedEuler scheme.


The effects of moisture adsorption and desorption in residential buildings is studied in detail. Energy-conserving and conventional residences are examined, and building loads are disaggregrated into their thermal moisture and source components. The report covers significant new analytical and experimental work. A detailed building-moisture-analysis technique is developed to be incorporated into the NBS building analysis program TARP. The model is validated against field and laboratory data with good results.


In classical optimization problems under discrete choice models, the decision maker can control at most one attribute for each choice. Usually, this attribute is the price of a product. However, price is not the only attribute that can impact both the product's market share and profit margin. This paper studies a generalization of these problems, which allows multiple attributes to be controlled for each choice of product. Past research showed that we can solve the classical optimization problems efficiently, using methods like the market share reformulation. However, these methods do not apply to the generalized problems. We showed that such problems are still tractable, and can be solved efficiently as conic programs. This argument applies to optimization problems under multinomial logit models, and applies to problems under nested logit models when certain assumptions hold. These generalized problems are very common in retail and transportation industries. This paper allows practitioners to solve such problems directly using commercial solvers.


This paper evaluates parental leave policies across six Anglophone countries (Australia, Canada, Ireland, New Zealand, the UK and the USA) to assess system fit with a liberal welfare regime classification. The focus is on comparison within welfare regime classification (rather than between regimes), enabling complexity and variation to be explored. The comparative policy analysis uses national government and international Organization for Economic Cooperation and Development data sources with case studies of policy change between 2004 and 2014 in Australia and the UK. Evidence suggests that contrary to market-oriented, liberal welfare regime predictions, there has been an expanding role of the state in developing parental leave policies, extending their duration and increasing the payment level. With the exception of the USA, parental leave provision, predominately maternal in focus, is embedded in the state policies of contemporary liberal welfare countries.


Photodynamic therapy is extremely effective in the treatment of actinic keratosis, and in many ways, is surpassing other currently used treatment modalities; however, more studies need to be conducted in order to maximize PDT's therapeutic effects and increase patient tolerance, while minimizing adverse events, an expert says.


Finned-tube heat exchangers are common and vital components in many energy systems. One primary application affecting a large fraction of any nation is peak electrical power usage for residential air conditioning systems in which the finned-tube heat exchangers are used. Due to very high demand for electric power, quick-starting of turbines or internal combustion units are used to meet peak demand. But with CO 2 , NOX, and particulate emissions being directly tied to energy production and use, there was a need for efficiency improvements in the heat exchanger. Because of the complex nature of the flow and the number of possible heat exchanger designs the flue gas side performance has not been addressed in a comprehensive manner. For typical applications of this type of heat exchangers, the flue gas side resistance is generally the controlling total thermal resistance. In recognition of the need for continual efficiency improvement, which is characterized by a trade-off between heat transfer and pressure drop, this study has been taken up.


As the emerging economies and major developing members of WTO, the bilateral trade of China and Brazil has grown robustly over the past few years, although with the conflicts on trade frictions and anti-dumping issues. The foreign direct investment from China to Brazil has also increased rapidly under the effect of kinds of factors. The aims of this paper are to examine the causal relationship between China's outflow foreign direct investment (OFDI) and trade (imports and exports) to Brazil, and to find out whether exports from China are complements or substitute to the FDI in Brazil. The results indicate the growth of China's imports of primary products and exports of manufactured products cause the growth on OFDI to Brazil significantly, while the OFDI to Brazil shows no significant causes on China-Brazil bilateral trade values.

The poor dispersion of carbon based nanomaterials without strong acid pretreatment in aqueous solution is a fundamental problem, limiting its applications in biology-related fields. A good dispersion of multi-walled carbon nanotubes (MWCNTs) in water was realized by 50 wt.% phytic acid (PA) solution. As an application case, the PA–MWCNTs dispersion in aqueous solution was used for the immobilization of horseradish peroxidase (HRP) and its direct electrochemistry was realized. The constructed biosensor has a sound limit of detection, wide linear range, and high affinity for hydrogen peroxide (H2O2) as well as being free from interference of co-existing electro-active species.


Using aniline and benzaldehyde as raw materials, p,p-diaminotriphenylmethane(DTM) was synthesized. Co-condensation type poly(amic acid) was prepared by using p,p-diaminotriphenylmethane as the co-diamine monomer and pyromellitic dianhydride(PMDA) as the the dianhydride monomer. And then the nonlinear optical polyimide(NLOPI) attached with azobenzene chromophore side-chain was synthesized by diazo coupling reaction of 4-nitrobenzenediazonium tetrafluoroborate to poly(amic acid) in 1-methyl-2-pyrrolidone(NMP) and imidization reaction at 250 ℃. The designed chemical structure of production can be proved in the infrared spectrum and ultraviolet-visible absorption spectrum. The NLOPI exhibits UV-Vis absorption of the azobenzene chromophore at the wavelength of about 330 nm and 490 nm. The third-order nonlinear optical property of NLOPI was studied by degenerate four-wave mixing(DFWM). Third-order nonlinear susceptibility of NLOPI is 3 28×10 -10 esu(4 58×10 -18 m 2/W). It is indicated that NLOPI has strong optical information storage through DFWM. Forward pumping light(I_f) and detecting light(I_p) are prime writing light, however backward pumping light(I_b) is principal reading light. It is proved that optical information storage can be caused by photo-induced trans-cis isomerization of azobenzene.


We develop a general low-energy multiple-scattering partial-wave theory for gapless topological insulator (TI) surfaces in the presence of magnetic impurities. As applications, we discuss the differential cross section (CS) $d\Lambda/d\varphi$, the total CS $\Lambda_{tot}$, the Hall component of resistivity $\Omega$, and inverse momentum relaxation time $\Gamma_{M}$ for single- and two-centered magnetic scattering. We show that differing from the nonmagnetic impurity scattering, $s\mathtt{-}$wave approximation is not advisable and convergent in the present case. The symmetry of CS is reduced and the backscattering occurs and becomes stronger with increasing the effective magnetic moment $M$ of single magnetic impurity. We show a non-zero perpendicular resistivity component $\Omega$, which may be useful for tuning the Hall voltage of the sample. Consistent with the analysis of $d\Lambda /d\varphi$, by comparing $\Gamma_{M}$ with $\Lambda_{tot}$, we can determine different weights of backscattering and forward scattering. Similar to CS, $\Omega$ and $\Gamma_{M}$ also exhibit oscillating behavior for multiple magnetic scattering centers due to interference effect.


We address the problem of learning over multiple inter-dependent temporal sequences where dependencies are modeled by a graph. We propose a model that is able to simultaneously fill in missing values and predict future ones. This approach is based on representation learning techniques, where temporal data are represented in a latent vector space. Information completion (missing values) and prediction are then performed on this latent representation. In particular, the model allows us to perform both tasks using a unique formalism, whereas most often they are addressed separately using different methods. The model has been tested for a concrete application: cartraffic forecasting where each time series characterizes a particular road and where the graph structure corresponds to the road map of the city.

A process for the extraction of alumina from aluminum-containing silicates is disclosed. The process comprises acid leaching of the raw material, iron extraction, precipitation of the aluminum fraction as the aluminum chloride hexahydrate, removal of sodium chloride and calcination to alumina. The process can be made continuous with substantial regeneration and recycling of process components.


Device-to-device (D2D) communications are envisioned as a critical technology to support future ubiquitous mobile communications applications. However, the requirements of high mobility and low latency seriously constrain the performance improvement of D2D communications. In this letter, we investigate a deep reinforcement learning (DRL) based scheme of power and resource allocation for maximizing the throughput of D2D users (DUEs) and cellular users (CUEs). Based on DRL theory, D2D pairs are defined as distributed multiple agents, which aim to adaptively select the transmission power and resources to ease the co-channel interference without any prior information. Furthermore, a priority sampling based dueling double deep Q-network (PS-D3QN) distributed algorithm is proposed to help agents to learn the predominant features. Simulation results show that the proposed algorithm has higher throughput than the existing DRL algorithms with a strict delay constraint. Particularly, the probability that the agent selects high power decreases with the increase of remaining transmission time, which proves the agents effectively learn and dynamically sense the impacts of the delay constraint.


[Extract] The purpose of this paper is to explore ethical research practice in the field of child and adolescent mental health and in doing so contribute to the overall development of the research capacity of mental health practitioners and researchers (Gould, 2010). Social work practice is changing; research is now an integral part of practice. The need for practitioners to be able to engage in research is becoming more important both for clients, organisations and communities. We should assume that research and practice are not mutually exclusive and that as practitioners, committed to social justice and human rights, we are also social researchers who embrace these same commitments. This paper explores the link between socially just practice, research and ethics; and highlights the political nature of not only knowledge creation but also the relationship between researcher and researched. The paper concludes that our commitment to our clients and their communities is strengthened not only by an evidence base but also ethical research practice that embodies and manifests the principles of human rights and social justice.


We study flexural vibrations of a thin rectangular cross section cantilever beam submerged in a quiescent viscous fluid. The cantilever is subject to base excitation and undergoes oscillations whose amplitude is comparable with its width. The structure is modeled as an Euler-Bernoulli beam and the fluid-structure interaction is captured through a nonlinear complex-valued hydrodynamic function which accounts for added mass and fluid damping. Results from a parametric 2D computational fluid dynamics analysis of an oscillating rigid lamina, representative of a generic beam cross section, are used to establish the dependence of the hydrodynamic function on the governing flow parameters. It is found that, as the frequency and amplitude of the vibration increase, vortex shedding and convection phenomena are enhanced, thus promoting nonlinear hydrodynamic damping. We derive a computationally efficient reduced order modal model for beam oscillations incorporating the non-linear hydrodynamic function and we validate theoretical results against experiments on underwater vibrations flexible beams.Copyright © 2012 by ASME


Preservatives in water-based cosmetics are essential yet greatly criticised. Although there are a variety of preservatives on the market, manufacturers tend to stick to a small trusted variety to provide robust protection from microbial contamination with the promise of low levels of potential side effects.


This paper describes how the author came to learn, through nine months of participant observation, how high steel ironworkers feel and act towards the dangers of their work. Ironworkers define much of their work situation as dangerous, and have developed, out of interactions about this common problem, collectively shared perspectives for enhancing control over the work situation. These processes of control include testing and assessing other workers, communicating these evaluations to others, and establishing worker reputations. Similar processes of control are applied to bosses, contractors, and others whose actions impinge on worker autonomy and self-interest. These processes of control are very analogous to those describing other dangerous occupations. The perception of danger by workers in quite different occupations leads them to develop similar mechanisms of control over their work fellows and environment.


In this paper, we present the analysis of long‐term (since 1989) hydrochemical data from two small (ca 1 km2) catchments in Central Scotland. Both catchments have experienced marked reductions in acid deposition. Time‐series analysis of stream water alkalinity, although systematically changing as a result of recovery from acidification, was used to conceptualize how the composition and contribution of different hydrological sources responded over the study period. Nonlinear curve fitting methods allowed the temporal changes in concentration–discharge relationships to be sufficiently well described to assess the impact of reduced acid deposition on storm flow and baseflow hydrochemistry. A Bayesian compositional analysis was applied to facilitate chemically based hydrograph separation. This allowed temporal variation over longer time periods in catchment‐scale hydrological source contributions (specifically groundwater) to be estimated. Although these showed no systematic trend, they did differ between the two catchments, most likely as a result of small, but significant differences in the riparian soil cover. Understanding such changes to high and low flows over time is of paramount importance as such flow extremes have the most relevance to applied problems, particularly those related to environmental change.

Dermatology Life Quality Index (DLQI) is the most common health‐related quality of life measure in dermatology that is widely used in treatment guidelines for psoriasis. Eight of the 10 questions of the DLQI offer a 'not relevant' response (NRR) option that is scored as the item had no impact on patients' life at all.


The tensile fatigue tests as well as tensile constant elongation-rate (CER) tests for GFRP/metal conical shaped joint, GFRP/metal adhesive joint, and GFRP/metal bolted joint are carried out under various loading rates and temperatures. The tensile fatigue strength as well as the CER strength for these three kinds of GFRP/metal joints depends clearly on time and temperature. The same time-temperature superposition principle for the deformation of matrix resin holds for the CER and fatigue strengths of the corresponding GFRP/metal joint. Therefore, the master curves of fatigue strength for those GFRP/metal joints can be obtained. It was clarified from these master curves that the dependence of time to failure, temperature and number of cycles to failure on fatigue failure load of each GFRP/metal joint shows very characteristic behavior, respectively, and that these dependences on the fatigue failure load of composite structures synthetically evaluated using temperature.

Multithreading is very effective at tolerating the latency of remote memory accesses in distributed memory parallel computers, but does nothing to reduce the number or cost of those memory accesses. Compiler techniques and runtime approaches, such as caching remote memory accesses and prefetching, are often used to reduce the number of remote memory accesses. Another approach to reduce the number of remote memory access messages is thread migration, which exploits spatial locality by making the entire memory space of any processing element (PE) local. Nomadic Threads are compiler-generated fine-grain threads that migrate between PEs to access data. The runtime system that implements the Nomadic Threads architecture has several attractive features, including support for migrating significant amounts of work, the ability to mix caching and migratory remote memory accesses, and low scheduling complexity. Our straightforward implementation shows that migration may be easily added to many multithreading runtime systems. We also present some unique behavior characteristics of migratory programs to help determine when migration is appropriate or not.


0196-6553/$36.00 Copyright 2014 by the Associa http://dx.doi.org/10.1016/j.ajic.2014.04.012 Background: The emergenceof the avian influenzaA (H7N9) inChinaduring 2013 illustrates the importance of health care professionals as a mediating channel between health agencies and the public. Our study examined health care professionals' risk perceptions considering their unique position as representing the health care systemandyet also beingpart of the public, hence a risk group. Recent studieshave examined the role of health professionals' personal risk perceptions and attitudes regarding compliance of the general public with vaccination. Our study examined how risk perception affects their risk analysis. Methods: We employed an online survey of Israeli health care professionals and the general public in Israel (N 1⁄4 240). Results: When risk perception is relatively low, health care professionals tend to base their attitudes toward vaccines on analytical knowledge (Rc 1⁄4 0.315; P < .05), whereas in situations with high risk perception, the results did not indicate any significant difference between Israeli health professionals and the Israeli general public, hence both groups base their attitudes more on emotions and personal experience than on analytical knowledge. Conclusions: Public health organizations must consider the fact that health professionals are a group that cannot be automatically treated as an extension of the organization. When the risk is tangible and relevant, health care workers behave and act like everybody else. Our study contributes to understanding health care professionals' perceptions about vaccines and the thinking processes underlying such perceptions.

For Hyperloop passenger systems, we are discussing the problem of ensuring the tightness of a passenger capsule due to ultra-low pressure in the tube of the system. Based on the example of a particular system, we calculate the estimated time for the expiration of air from the capsule in an emergency situation. As a result, we are discussing several ways to improve the level of passenger safety associated with the leakage problem.


Reducing a liter of orange juice to a few grams of concentrated powder is what lossy compression is about. The taste of the restored beverage is similar to the taste of orange juice but has often lost some subtlety. We are more interested in sounds and images, but we face the same trade-off between quality and compression. Major applications are data storage and transmission through channels with a limited bandwidth. A transform coder decomposes a signal in an orthogonal basis and quantizes the decomposition coefficients. The distortion of the restored signal is minimized by optimizing the quantization, the basis and the bit allocation. The basic information theory necessary for understanding quantization properties is introduced. Distortion rate theory is first studied at high bit rates, in a Bayes framework, where signals are realizations of a random vector whose probability distribution is known a priori. This applies to audio coding, where signals are often modeled with Gaussian processes. High signal compression factors are obtained in sparse representations, where few non-zero coefficients are kept. Most of the bits are devoted to code the geometry of these non-zero coefficients, and the distortion is dominated by the resulting non-linear approximation term. Wavelet image transform codes illustrate these properties. JPEG and JPEG-2000 image compression standards are described. Speech Speech coding is used for telephony, where it may be of limited quality but good in-telligibility, and for higher quality teleconferencing. Telephone speech is limited to the frequency band 200-3400 Hz and is sampled at 8 kHz. A Pulse Code Modulation (PCM) that quantizes each sample on 8 bits produces a code with 64 kb/s (64 10 3 bits per second). This can be considerably reduced by removing some of the speech redundancy. The production of speech signals is well understood. Model based analysis-synthesis codes give intelligible speech at 2 kb/s. This is widely used for defense telecommunications [315, 460]. Digital cellular telephony uses 8 kb/s or less to reproduce more natural voices. Linear Predictive Codes (LPC) restore speech signals by filtering white noise or a pulse train with linear filters whose parameters are estimated and coded. For higher bit rates, the quality of LPC speech production is enhanced by exciting the linear filters with waveforms chosen from a larger family. These Code-Excited Linear Prediction (CELP) codes provide nearly perfect telephone quality at 16 kb/s. Audio Audio signals include speech but also music and all types of sounds. …


We investigate the effect of non-local synaptic enhancement within the framework of networks of formal neurons. Enhancement of nearby synapses on a common axon without simultaneous post- and presynaptic stimulation is modelled by a generalized Hebbian rule. The imprinted patterns of activity are no longer attractors of the network dynamics, but are processed instead. The network acts as a low band-pass filter for spatially uncorrelated patterns and can discriminate spatially correlated patterns, according to their degree and range of correlation. While the network is processing information, it still maintains some of the error-correcting properties of attractor neural networks.


OF THESIS EVALUATING THE EXPERIENCES OF FCS COOPERATIVE EXTENSION AGENTS USE OF POLICY, SYSTEMS AND ENVIRONMENTAL STRATEGIES TO REDUCE OBESITY IN RURAL COUNTIES High rates of obesity are seen across the country with rural areas disproportionately affected. Based on the socio-ecological model, policy, system, and environmental approaches targeted at the population level have the potential to create more sustainable health behavior change than individual level approaches. Historically, the Cooperative Extension Service (CES) has provided direct education related to healthy eating and active living in response to high obesity rates. Utilizing the resources and infrastructure of the CES, the Centers for Disease Control challenged CESs across the country to implement PSE strategies in counties with obesity rates greater than 40% through the CDC 1416 High Obesity Project. This qualitative study examined the experiences of Family and Consumer Science (FCS) Cooperative Extension Agents in conducting PSE strategies in addition to their direct education roles within their rural counties in an effort to reduce the high prevalence of obesity. Semi-structured, in-depth interviews with ten FCS Extension agents from Kentucky and Tennessee were conducted upon completion of the project and were analyzed thematically. These FCS agents encountered several barriers while implementing PSE strategies including inadequate training and poor communication regarding responsibilities and available resources. In addition, FCS agents found PSE work to be overwhelming and time consuming. Agents felt that support from project staff and their community partners allowed them to be successful. Findings from this study will be used to better prepare FCS agents in other rural counties across the country to conduct PSE work in an effort to reduce obesity prevalence in their communities.


A high-temperature and high-pressure nuclear magnetic resonance (NMR) probe has been developed to investigate chemical reactions in supercritical water up to 50 MPa and 500 °C. The NMR probe is of a continuous flow type with a high-pressure sample tube made of hot-pressed Si3N4 and a specially designed heat-resistant high-pressure seal. A mixing method was utilized to quickly realize the supercritical condition. The NMR probe can be used for in situ investigation of rapid reactions with several hundreds of ms half lives in continuously flowing supercritical water as well as slow equilibria under a stopped-flow condition.A high-temperature and high-pressure nuclear magnetic resonance (NMR) probe has been developed to investigate chemical reactions in supercritical water up to 50 MPa and 500 °C.

This paper aims at iterative learning control (ILC) design and analysis for a class of linear distributed parameter systems (DPSs) that may be hyperbolic, parabolic, or elliptic, and include many important physical processes such as diffusion, vibration, heat conduction and wave propagation as special cases. Owing to the linear characteristic of systems, the system equations are first cast into a matrix form in the Laplace transform domain. Then, through determination of a fundamental matrix, the system transfer function is precisely evaluated in a closed form. The derived transfer function clearly demonstrates the input-output relationship of system, and thus facilitates the consequent ILC design and convergence analysis in the frequency domain. The proposed control design scheme is able to deal with parametric and non-parametric uncertainties and makes full use of the process repetition, while avoids any simplification or discretization for the 3D dynamics of distributed parameter systems in the time, space, and iteration domains. In the end, an illustrative example is presented to demonstrate the efficacy of the proposed ILC scheme.

There are frequent reports of the illegal dumping of hazardous waste streams occurring across South Africa. There is also a general shortage of disposal facilities for hazardous waste and many existing facilities are not fully compliant. This status quo will now change with a new hazardous treatment and disposal facility at Vlakfontein, Gauteng.


This article attempts to explain the variation in Japanese official development assistance in eighteen Latin American countries for the period 1979 to 1993. The findings suggest that recipient need and some Japanese economic interests have influenced disbursements in the region. The study does not provide support for theories that claim that U.S. strategic and economic interests are important determinants of Japanese ODA decisions.


Four different simple, accurate and precise UV-spectrophotometric methods have been developed for the estimation of palbociclib (PB) in bulk and in-house capsule dosage form by zero order (Method I), zero order AUC (Method II), 'first order derivative UV-spectrophotometric (Method III), and first order AUC (Method IV) methods. The drug was dissolved in methanol (AR-Grade) and further dilution was made in double distilled water. Zero order was performed at λ max 220.00 nm of PB (Method I) and AUC was calculated between 215.40 nm - 228.20 nm wavelength (Method II). In Method-III zero-order spectra were derivatized into first-order and amplitude measured at 231.00 nm and the AUC was recorded between 224.00 nm - 240.60 nm (Method IV). PB followed linearity in the concentration range of 4.08-20.40 µg/mL with correlation coefficient (r2 )> 0.99 for PB.


We give explicit formulas for the first few coefficients of the Alekseev-Torossian associator and a second Drinfeld associator. This is done by analyzing the free and transitive action of the Grothendieck-Teichm\"uller group and its Lie algebra $\mathfrak{grt}_1$ on the set of Drinfeld associators. As a result we obtain that, up to a conjecture on multiple zeta values, both associators are not rational.


Sandstones and dolomites of the Permian upper part of the Minnelusa Formation are treated here as four-component systems consisting of fluid-filled pore space, quartz, dolomite, and anhydrite. Response equations of sonic, neutron, and density logs, plus the identity that the whole equals the sum of its parts, form a system of four simultaneous equations. With four equations and four unknowns, the composition of upper Minnelusa facies is defined by the three-log suite and can be calculated by solving a 4 x 4 matrix. Such calculations of facies composition help in establishing subsurface correlations and yield information on the diagenesis and physical character of upper Minnelusa sandstones and dolomites. Applications of composition calculations are illustrated by examples drawn from the area of the West Mellott field (T/sub 52/N, R68W), where the upper Minnelusa is at depths of about 7000 ft (2100 m).


The United States has long been described as a nation of immigrants, but it is also a nation of religions in which Muslims and Methodists, Buddhists and Baptists live and work side by side. This book explores that nation of religions, focusing on how four recently arrived religious communities - Muslims, Buddhists, Hindus, and Sikhs - are shaping and, in turn, being shaped by American values. For a generation, scholars have been documenting how the landmark legislation that loosened immigration restrictions in 1965 catalyzed the development of the United States as "a nation of Buddhists, Confucianists, and Taoists, as well as Christians," as Supreme Court Justice, Tom Clark put it. The contributors to this volume take U.S. religious diversity not as a proposition to be proved but as the truism it has become. Essays address not whether the United States is a Christian or a multireligious nation - clearly, it is both - but how religious diversity is changing the public values, rites, and institutions of the nation and how those values, rites, and institutions are affecting religions that are centuries old yet relatively new in America. This conversation makes an important contribution to the intensifying public debate about the appropriate role of religion in American politics and society.

The study developed and validated an instrument for measuring secondary school students' academic locus of control. Three research questions guided the development of the Secondary School Students' Academic Locus of Control Scale (SSSALCS). The sample size used for the study was two hundred and eighty (280) secondary students comprised (133 boys and 147 girls) distributed in the 10 sampled school in Nsukka Education Zone, Enugu State. In the development of the SSSALCS, 65 items were, first, written after which the items were subjected to face validation by experts in educational measurement and evaluation. After the face validation, 5 items were dropped while the remaining 60 items were subjected to construct validation using SPSS version 25. Thirty-three (33) factorial pure items that were loaded into four (4) factors emerged. The four (4) factors were: (i) Personal Internal Locus of Control with 10 items, General internal Locus of Control with 8 items, (iii) Personal External Locus of Control with 9 items, and General External Locus of Control with 6 items. The reliability estimates of the 4-factors ranges from 0.79 to 0.91. A 4-factor correlation model was specified with the loaded items on each factor and was subjected to confirmatory factor analysis using lavaan package. The result indicated a harmony between the model and the data (CFI=0.97, TLI=0.94, SMSEA=0.06, and SRMR=0.05). It was recommended, among others, that the instrument should be used to measure secondary school students' academic locus of control .

In truss structural optimization the most frequently optimized factor of a structure is its weight. The minimization of weight contributes not only to savings in material, but also in other aspects of the structure such as number of elements used, number of welds needed, outer surface area, etc. This research aims to show the difference in optimal solutions for four different topological cases of a typical trapezoidal roof truss looking at their effects on overall outer surface area. The truss layouts are optimized for sizing, and a combination of sizing and shape with a minimal weight objective function. In order to ensure the most practically applicable solutions the example optimized in this paper uses dynamic constraints for buckling, stress constraints, and nodal displacement constraints. The overall outer surface area for all cases is compared, as surface protection accounts for a substantial part of the total cost of roof truss construction. Optimal solutions show a lack of correlation between weight and surface area, which is discussed in the conclusion. ARTICLE HISTORY Received: 13.05.2020. Accepted: 02.06.2020.

In this work, we utilize the framework of compressed sensing (CS) for distributed device detection and resource allocation in large-scale machine-to-machine (M2M) communication networks. The devices deployed in the network are partitioned into clusters according to some pre-defined criteria. Moreover, the devices in each cluster are assigned a unique signature of a particular design that can be used to indicate their active status to the network. The proposed scheme in this work mainly consists of two essential steps: (i) The base station (BS) detects the active clusters and the number of active devices in each cluster using a novel block sketching algorithm, and then assigns a certain amount of resources accordingly. (ii) Each active device detects its ranking among all the active devices in its cluster using an enhanced greedy algorithm and accesses the corresponding resource for transmission based on the ranking. By exploiting the correlation in the device behaviors and the sparsity in the activation pattern of the M2M devices, the device detection problem is thus tackled as a CS support recovery procedure for a particular binary block-sparse signal $x\in\mathbb{B}^N$ -- with block sparsity $K_B$ and in-block sparsity $K_I$ over block size $d$. Theoretical analysis shows that the activation pattern of the M2M devices can be reliably reconstructed within an acquisition time of $\mathcal{O}(\max\{K_B\log N, K_BK_I\log d\})$, which achieves a better scaling and less computational complexity of $\mathcal{O}(N(K_I^2+\log N))$ compared with standard CS algorithms. Moreover, extensive simulations confirm the robustness of the proposed scheme in the detection process, especially in terms of higher detection probability and reduced access delay when compared with conventional schemes like LTE random access (RA) procedure and classic cluster-based access approaches.


Metallic ferromagnets with strongly interacting electrons often exhibit remarkable electronic phases such as ferromagnetic superconductivity, complex spin textures, and nontrivial topology. In this report, we discuss the synthesis of a layered magnetic metal NiTa 4 Se 8 (or Ni 1 / 4 TaSe 2 ) with a Curie temperature of 58 Kelvin. Magnetization data and ab initio calculations indicate that the nickel atoms host uniaxial ferromagnetic order of about 0.7 µ B per atom, while an even smaller moment is generated in the itinerant tantalum conduction electrons. Strong correlations are evident in flat bands near the Fermi level, a high heat capacity coefficient, and a high Kadowaki-Woods ratio. When the system is diluted of magnetic ions, the samples become superconducting below about 2 Kelvin. Remarkably, electron and hole Fermi surfaces are associated with opposite spin polariza-tion. We discuss the implications of this feature on the superconductivity that emerges near itinerant ferromagnetism in this material, including the possibility of spin-polarized superconductivity.


The mobile Virtual Private Network (MVPN) of Internet Engineering Task Force (IETF) is not designed to support NEwork MObility (NEMO) and is not suitable for real-time applications. Therefore, an architecture and protocol which supports VPN in NEMO are needed. In this paper, we proposed the cost-reduced secure mobility management scheme (CR-SeMMS) which is designed for real-time applications in conjunction with VPN and also which is based on the session initiation protocol (SIP). Our scheme is to support MVPN in NEMO, so that the session is well maintained while the entire network is moved. Further, in order to reduce the authentication delay time which considers as a delaying factor in hands-off operations, the signaling time which occurs to maintain the session is shortened through proposing the hands-off scheme adopting an authentication method based on HMAC based One Time Password (HOTP). Finally, our simulation results show the improvement of the average hands-off performance time between our proposed scheme and the existing schemes.
