With the rise of blockchain technology, data sharing between organizations is often established in a distributed blockchain ledger that is decentralized and tamperproof and has a low trust cost. However, traditional blockchain technology does not adequately support the on-chain storage of massive data, and all the on-chain stored data are completely open and transparent to participants; consequently, it is impossible to meet the user's needs for privacy protection. In this study, we designed a scalable data access control method for blockchains; this method extends the storage forms of the blockchain to support the chaining and sharing of large files, ensures that the traceable data in the chaining process cannot be tampered with, and introduces the attribute authority mechanism in peer nodes to improve the reliability and efficiency of attribute authorization. To verify the correctness and security of the method, we built a complete prototype system based on the Hyperledger Fabric license chain and performed rigorous evaluations on the indicators of physical resource consumption and performance using the Hyperledger Caliper evaluation model. The results showed that the proposed method achieved a good balance in terms of performance, safety, and resource consumption indicators.


Laser speckle contrast imaging (LSCI) is becoming an established method for full-field imaging of blood flow dynamics in animal models. Blood flow pulsation originated from heart beat affects blood flow measurement results of LSCI and it is considered as major physiology noise source for most biomedical applications. But in some biomedical applications, the details of the pulsation process might provide useful information for disease diagnostics. In this study, we investigated the ability as well as the limitation of LSCI in monitoring flow pulsation in phantom study. Both intralipid (2% - 5%) and human whole blood samples are used in phantom study. A syringe pump is controlled by a computer-programmable motor controller and liquid phantom is pushed through a 400 μm ID capillary tube by the pump at different pulsation patterns, varied in frequency (1-7 Hz), valley-to-peak ratio (10%-50%), acceleration/deceleration rate, etc. Speckle contrast images are acquired at 15-30 frames-per-seconds. Our results show: (1) it is very hard for LSCI to pick up signals from high frequency pulsation (5-7 Hz), which is close to the heart back frequency of rats. This might be caused by the nature of fluid dynamics of blood during pulsation. LSCI might not work well for animal models in detecting pulsation. (2) With low frequency pulsation (1 Hz, close to human normal pulsation rate), our experimental results shows from most pulsation patterns, LSCI could catch the fine details of the blood flow change in a cycle. LSCI might be used for studying human blood flow pulsation.


Abstract The brightness of the planet Jupiter is found to be related to mean annual and monthly relative sunspot numbers which are used to indicate the general level of solar activity. The evidence for the relationship is presented and is examined for possible meteorological implications.

Subject matter / theme. A research of the conflict impact on the economic security of the enterprise is presented. The conflict arisen in the enterprise can disengage the employees' activities which results in hindering the successful work and is reflected in all areas of the enterprise operation. For this reason, a favorable social and psychological atmosphere is essential.Purposes / objectives. The purpose of this article is the research of the conflict impact on the economic security of the enterprise.To achieve the purpose, it is necessary to meet the objectives:1.             To define the classification of conflicts in the enterprise depending on the conflict subject or the scope of its occurrence. To clarify the notion of contradiction.2.             To identify the internal threats to the financial and economic security of the enterprise, the emergence of which can be provoked by an unfavorable socio-psychological situation in the team, the growth of moral tension and the unsettled in proper time conflict in the team of the enterprise.3.             To suggest a conceptual scheme of the stages for forming an effective system of employee motivation at the enterprise.Methodology. The research uses economic security analysis with the use of conflictology theory; the economic and statistical methods of analysis, institutional approach and dialectical method of scientific cognition were applied at studying the role and impact of the conflict on the economic security of an enterprise.Results. There is no society with no contradictions, no conflicts, and there is no society with no certain level of security. Economic security is determined by the potential for conflict. With a low conflict level in the society and a higher security level, the external threats can be adequately neutralized by the system at other conditions being equal.The socio-economic conflict is a confrontation between the subjects of economic activity, their values and socio-economic interests.The notion of contradiction is broader in its content than the notion of an economic conflict. The economic conflict arises when people (as members of various social groups) realize the existing contradictions in their economic interests. The contradictions are objective and general; and the conflict is objective-subjective and specific.Conclusions / significance. Conflict in an enterprise is a specific kind of social conflict expressed in a clash of two or more opposing positions that concern both personal and business interests. Any conflict can be both creative and useful for the enterprise activity, as well as destructive and undesirable. Which consequences exactly will arise as a result of the conflict for the enterprise, mostly depends on the behavior style of the enterprise management in relation to the arisen conflict. Since the conflict affects all areas of activity, and conductors between the socio-psychological situation and the enterprise performance are employees of the enterprise, the presence of social tension in the work collective directly affects the economic security of the enterprise. In order to successfully resolve the conflict, any clash of interests should be considered as an opportunity for the emergence of new alternatives.

The serum proteins albumin and γ-globulin were precipitated by two polyhaptenic azobenzenearsonic acid dyes, at pH values in the region of or below the isoelectric points of the proteins. The occurrence of an optimum zone of precipitation suggests either a colloidal precipitation or the formation of a framework of dye and protein. The molecular ratios of dye to protein in the precipitate suggest increasing aggregation of the dye with lowering pH. The aggregation appears to be an acid constant effect. An estimate of the number of protein combining groups for one of the dyes is 22 for albumin, and 44 for γ-globulin. At pH values between 5.0 and 5.4, at which albumin is not precipitated, the precipitation of γ-globulin by the dyes is dramatically reduced by the presence of albumin. Apparently albumin forms soluble complexes with either the dye or γ-globulin or with both these substances.


Abstract: Popular media, communitarian writings, and recent management literature suggest that communities and organizations are rent by factional mischief: by individuals and groups who pursue their own selfish interests without regard for the common good. An emerging solution to this problem is "transformational" leadership, which seeks to refocus individuals' attention on higher visions and collective goals. The dangers of such a solution were identified by James Madison at the Constitutional Convention of 1787; and mechanisms to thwart it were designed into the framers' system of government. This article examines Madison's objections and the implications of his political theory for the leadership of modern organizations.


A novel charge pump with variable frequency modulation (VFM) is proposed in this paper. To provide base for its design and improvement, detailed models for VFM charge pump are derived. And it is successfully implemented for the charge pump to introduce a voltage controlled oscillator (VCO) to control the switching frequency, which results in its high efficiency and low ripple output both at high load and light load. The chip is designed and fabricated in TSMC 0.35um mixed signal process. The simulation and test results show that high efficiency (up to 75%) and very low ripple output ( around 10 mV) is realized as expected. Besides, the accuracy of the model's prediction is proved.


On March 15, 2013, the Little Traverse Bay Bands of Odawa Indians (LTBB) became the third tribal nation to recognize same sex unions. The LTBB statute, Waganakising Odawak Statute 2013-003, defines marriage as "the legal and voluntary union of two persons to the exclusion of all others." The Coquille Tribe, in 2009, and Suquamish Tribe, in 2011, both previously recognized same sex unions. Unlike the Coquille Tribe, located within Oregon, and the Suquamish Tribe, located within Washington, LTBB's tribal territory is located within Michigan, a state that does not currently recognize same sex marriages. Accordingly, some may question the authority of LTBB and similarly situated tribal nations to enact provisions, such as the Waganakising Odawak Statute 2013-003, that conflict with state policy. This article addresses issues surrounding the authority of tribal nations to enact provisions allowing for same-sex marriage or unions.

A graphene–semiconductor heterojunction is very attractive for realizing highly sensitive phototransistors due to the strong absorption of the semiconductor layer and the fast charge transport in the graphene. However, the photoresponse is usually limited to a narrow spectral range determined by the bandgap of the semiconductor. Here, an organic heterojunction (C60/pentacene) is incorporated on graphene to realize a broadband (405–1550 nm) phototransistor with a high gain of 5.2 × 105 and a response time down to 275 µs. The visible and near‐infrared parts of the photoresponsivity (9127 A W−1@650 nm and 1800 A W−1@808 nm) come from the absorption of the organic layer and the graphene, respectively. For the first time, a bi‐directional (positive and negative) photoresponse is demonstrated at different wavelengths, due to the opposite charge transfer direction of the photoexcited carriers enforced by the unique band alignment. Such tunability will enable new functionalities such as large‐scale real‐time optical image and infrared focal plane array detection in the future.


Obtaining local and global planarity is one of the prime criteria in dielectric and metal planarizations. Although Chemical Mechanical Planarization (CMP) helps us achieve this criterion in constant pattern density surfaces, the same is not true for variable pattern density surfaces this results in formation of global step heights across the die. This paper provides a pressure open loop control algorithms for obtaining planarity across a die containing variations in pattern densities. Based on the variation of pattern density and surface heights across the die, the surfaces are separated into zones and the pressure is varied spatially and/or temporally to obtain uniform surface heights, with enhanced step height uniformity. One of the algorithms looks ahead and recalculates/modifies the pressure values by identifying the step heights that could be formed after a specified time step. The final surface predictions have improved uniformity on the upper surface as well as on the step heights across the entire die. The simulation would help us track the polishing process for each time step and guide us with the optimized pressure values that can be applied in order to an uniform final surface evolution.


The conventional approach to exciting high phase velocity waves in plasmas is to employ a laser pulse moving in the direction of the desired particle acceleration. Photon downshifting then causes momentum transfer to the plasma and wave excitation. Novel approaches to plasma wake excitation, colliding-beam accelerator (CBA), which involve photon exchange between the long and short counter-propagating laser beams, are described. Depending on the frequency detuning Δω between beams and duration τL of the short pulse, there are two approaches to CBA. First approach assumes (τL≈2/ωp). Photons exchanged between the beams deposit their recoil momentum in the plasma driving the plasma wake. Frequency detuning between the beams determines the direction of the photon exchange, thereby controlling the phase of the plasma wake. This phase control can be used for reversing the slippage of the accelerated particles with respect to the wake. A variation on the same theme, super-beatwave accelerator, is also described. ...


We consider problematic features of SFAS 123 (R) and then present a new approach to the accounting for Employee Stock Options (ESO) that addresses prominent criticisms of both grant date accounting (inaccurate estimates) and exercise date accounting (delayed recognition). The accounting for our Verified Fair Value (VFV) approach begins with a model-derived recognition of an ESO obligation, which is presumed to be the best available estimate of the present value of the Realized Intrinsic Value (RIV). Distinctive features of the VFV approach include disaggregation of the ESO expense into accruals and fair-value changes and a truing-up mechanism which could provide useful feedback about the accuracy of ESO model valuations. The recognition of subsequent changes in the intrinsic and time values of the option converge on a value that is exactly equal to the issuer's cash cost for the option. Information provided under the VFV approach would align with the requirements to reconcile comprehensive income and cash flows presently contemplated by the IASB and FASB in their Discussion Paper for the Financial Statement Presentation Project. Verified Fair Value is accurate and reliable, transparent, readily verified, easily auditable, practical and promotes consistency and transparency. Introduction and Motivation The requirement in the 2004 revision to SFAS 123 (FASB 2004, Share-Based Payment) and the issue of IFRS 2 (IASB 2004, Share-Based Payment) that mandated fair value measurement and subsequent expensing of Employee Stock Options (ESO) led to accounting changes both illusory and real. This paper addresses the illusion of fair value (FV) reporting in these standards, and their foundation of measurements that insulate a one-time estimate from the kinds of corrections and adjustments that affect most other accounts,1 income smoothing, and potentially understated ESO obligations. We question the straight-line model of employee service cost behavior and the absence of interest expense for arrangements that are constructively deferred compensation. We argue for a Verified Fair Value (VFV) accounting approach that includes a combination of grant-date liability recognition, report-date measurement of changes in that liability, and a wholly accurate exercise date cost reporting. Notwithstanding the apparent resolution of the contentious discussion of ESO accounting that followed the issue of SFAS 123 (R), we believe that there are several factors that make our examination timely and worth consideration. These include: 1) OBS Financing The potential impact of ESO settlement costs on the corporate cash balance may be just as sudden and unwelcome as adverse developments in exposures created by such contracts as a pension liability, credit default swap or a loan guarantee. The global credit crisis that began in 2007 underscores the potentially catastrophic impact of underestimated liabilities. Botosan and Plumlee (200 1 ) provide evidence that, relative to voluntary FV reporting under SFAS 123, many firms had under-reported the expense. In the absence of a final truing up of the actual costs, the potential for under-reporting of actual true cost should concern statement users and standards setters. 2) Convergence and IFRS Adoption The "more likely than not" standard in FTN 48 (FASB 2006) may present global standard setters with the need to rethink accounting treatments currently guided by the "probably / reasonably possible / remote" language in SFAS 5 (FASB 1975). "More likely than not" judgments that ESO will in many cases result in an outflow of corporate cash and no material increase in shareholders' equity2 will present opportunities to rethink the nature of ESO arrangements and the accounting needed to achieve more representationally faithful treatment. 3) Improvements to Current Practice Disclosure and reconciliation requirements under VFV could provide useful feedback on the accuracy of ESO valuation models, an aspect of current practice for which there is relatively little empirical evidence. …


Extracting information from a polarimetric radar representation usually consists in decomposing it with target decomposition algorithms. This first step can be seen as a geometric analysis of the polarimetric information: the identification of physical radar scattering mechanisms. The problem is that average physical parameters are estimated. As a consequence, these parameters might not describe correctly any of the land cover types that can be mixed together into the radar resolution cell. Therefore, using the polarimetric parameters for land cover classification is challenging. The novelty of the method is to propose a thematic analysis of the polarimetric information preceding the geometric one. The objective is to assess if splitting off polarimetric information on a land cover type basis before applying usual target decomposition algorithms can produce more consistent radar scattering mechanisms when land cover classes are mixed inside the radar resolution cell. A cooperative fusion framework in which very high-resolution optical images are used to unmix physical radar scattering mechanisms is proposed. For bare soil and forests, we point out that a linear unmixing model applied to the covariance matrix is able to split off polarimetric information on a land cover type basis. The assessment of the unmixed radar matrices is carried out with polarimetric radar images from the Radarsat-2 satellite. It was found that despite speckle, the reconstructed radar information after the unmixing process is statistically relevant with the observations. The question whether the unmixed radar images contain relevant thematic information is more challenging, but results tend to validate this property. This method could be used to have a better estimation of vegetation biomass in the context of open forested areas.


Hundreds of artists have illustrated the Quixote (1605) following their own understanding and views of the text, at times pushed by the needs and desires of an editor or institution, but all trying to capture and replicate in the few instances afforded by their creations the genius of Cervantes, in their particular time and place, and for their intended public. The illustrators have been compelled to create images capable of representing complex narrative meanings, settings, and characterization as visual readings. Their designs and engravings attempt to make visible the imaginary reality conceived by the author in his text; in this manner they are both a useful critical guide and an effective graphic reference to see what we are told, to confirm the reality of the words. And at their best, they graphically illuminate and elucidate the text for the reader as visual annotations. Although some selective illustrations are occasionally included in critical and bibliographical studies, the complete iconographic record has remained inaccessible until now. Since 2003 the Cervantes Project, in collaboration with the TEES Center for the Studies of Digital Libraries at Texas A&M University, and with the support of the Cushing Memorial Library, the Cervantes Chair at the Universidad de Castilla-La Mancha, and the National Endowment of the Humanities, started to digitize, annotate and make available online in the form of a fully documented and accessible hypertextual digital archive the tens of thousands representations and visual readings constituted by the illustrations of the Quixote. At present the Textual Iconography of the Quixote archive includes over 50,000 digital images from over 850 editions. Our current research involves how best to reimagine and interpret the rich visual, textual and documentary information contained in the archive. We present here the taxonomic organization of the archive and our approach to integrate through metadata words and images in order to create new forms of reading and learning.


Most explanations for Taiwan's trade surpluses have focused on the country's competitive advantages, in particular, on the role of Taiwan's nominal exchange rate policy in limiting the appreciation of the New Taiwan (NT) dollar. However, other factors that may be traced to Taiwan's exchange rate policy have received less attention, and may also have contributed to the country's remarkable trade surpluses. As discussed below, low inflation appears to have been an important contributor to Taiwan's competitiveness in the 1980s. Furthermore, Taiwan's trade surpluses in the 1980s reflect an increase in Taiwan's domestic saving and a sharp decline in investment as a proportion of GNP.


By saving rather than spending their freed-up dollars and by avoiding lifestyle creep, investors at this life stage can make significant headway.

The emergence of various forms of manipulation and exploitation has resulted in rampant trafficking in persons, in which children are also trafficked. Basically, children as the next generation of the nation have a role in ensuring the continuity of the nation. Therefore, children need to get ample opportunities to grow and develop. This study was conducted with the aim of describing how legal protection of children as victims of trafficking in persons. The research method used in this study is normative legal research which is studied using a statutory approach (statute approach). The results of this study show that children are very vulnerable to becoming victims of child trafficking for the purpose of exploitation. The law relating to child trafficking has been in force and has binding legal force, but its enforcement has not been sufficient to provide a deterrent effect for perpetrators. In this case, children as victims should get legal protection which includes protection of their dignity, dignity, and fulfillment of their rights. However, in the criminal justice system, victims are often given less attention, in reality Indonesian law only focuses on punishing perpetrators and overrides the rights and protection of victims.

The issue of tax evasion has always presented a challenge to policymakers in governments all over the world. A developing country's economic stability is almost entirely reliant on taxes and aid from other nations. Effective tax collection and capable tax administration are necessary to generate a sufficient amount of tax revenue. It would be possible to lessen the negative effects brought on by a decrease in tax revenue if governments in both developing and developed nations could better understand the factors that contribute to tax evasion and find effective ways to combat those factors. Numerous economic factors that affect tax evasion behavior have been mentioned in prior literature. However, research on the impact of tax evasion behavior in the Libyan context is lacking. Given this context, the current study, which empirically investigates the effect of education level, tax rate, and penalty rate on tax evasion behavior among self-employed taxpayers in Libya, will likely aid in shedding lighter on the causes of tax evasion. The data is gathered quantitatively by using a questionnaire. This study made use of the SPSS statistical package for social sciences. A framework for the proposed relationship between tax amnesty, educational attainment, tax and penalty rates, and tax evasion among self-employed taxpayers is what this study aims to achieve. The current study adds to the body of theoretical knowledge by highlighting the influences on the relationship between economic factors and tax evasion in Libya.

Keywords: Education level, Tax rate, Penalty rate, Tax evasion, Libya context.


A partial cDNA clone of the vitellogenin gene from the cockroach Blattella germanica has been isolated from a cDNA expression library using an anti-vitellin-vitellogenin antiserum probe. The analysis of cDNA inserts gave a sequence of 2,645 nucleotides corresponding to the 3' region. The deduced amino acid sequence is 825 residues long and is similar to the homologous portion of the vitellogenin of other insect species, especially that of the mosquito Aedes aegypti. RNA hybridization studies indicated that the vitellogenin gene expression is limited to the fat body of adult females. The pattern of expression during the first vitellogenic cycle was approximately parallel to that of vitellogenin production by the fat body previously described. The availability of a cDNA probe for the B. germanica vitellogenin gene represents a useful tool to study the molecular action of hormones affecting vitellogenin synthesis in this species.


A correlation between the orientation of [TCNE]•- (TCNE = tetracyanoethylene) bound to a [MnIII(por)]+ (por = substituted meso-tetraphenylporphyrin) and the magnitude of magnetic coupling for a series of previously prepared [Mn(por)][TCNE]·2PhMe linear-chain molecule-based ferrimagnets has been identified. The tetraphenylporphyrin (H2TPP), tetrakis(4-chlorophenyl)porphyrin (H2TClPP), tetrakis(4-methoxyphenyl)porphyrin (H2TOMePP), tetrakis(2-fluorophenyl)porphyrin (H2TFPP), and tetrakis(3,5-di-tert-butyl-4-hydroxyphenyl)porphyrin (H2TP'P) ligands have all been utilized. Previous structural determinations as the ditoluene solvates indicate that the Mn−N distance varies ∼2.6%, while the Mn−(N−C)TCNE bond angle varies by as much as 25.2% from the mean values over this series of compounds. Hence the overlap between the [TCNE]•- π* SOMO and the MnIII SOMO d orbitals plays a significant role in controlling the magnetic properties. From molecular orbital overlap considerations, as determined from semiempirical IN...


Ab initio calculations on monoprotonated BFH2 indicate that the B−H protonated 1a is 9.7 kcal/mol more stable than the F-protonated 1b. Thus the bonded electron pair of the B−H bond is a better donor than the nonbonded fluorine electron pair in BFH2.

However, the concentration of all metals was in the parts per billion (ug/l) range and well below international standards. Heavy metals in Tehran's drinking water therefore, do not pose a significant acute health hazard. 19 references, 2 tables.


In its various forms, acceleration continues to be an evidence-based and widely used service provided to gifted students but remains controversial and unsupported in legislation in most states. Case studies, current legislation, interviews with state directors of gifted education programs, and a deep dive into the 2018–2019 State of the States in Gifted Education revealed vast differences in state policies and approaches to providing gifted services especially when it comes to acceleration. Of the 44 state responses regarding content-based acceleration, nine indicated it is required, 12 said it is not, and 23 deemed it a local decision. When coupled with professional learning, subject acceleration triumphs as an effective method supporting student growth and talent development. With careful planning, the perceived barriers to subject acceleration can be overcome.

OBJECTIVE
To investigate the longitudinal associations of serum inflammatory markers and adipokines with joint symptoms and structures in participants with knee osteoarthritis (OA).

METHODS
Two hundred participants (46.5% female, mean age 63.1 years, mean BMI 29.5 kg/m2) from Tasmania part of the VIDEO (Vitamin D Effect on OA) study were randomly selected in the current study. Serum levels of 19 biomarkers, scores of Western Ontario and McMaster Universities Index (WOMAC), and magnetic resonance imaging-assessed knee structures were evaluated at baseline and month 24. The patterns of biomarkers were derived from principal component analysis and their association with knee symptoms and structures were examined using adjusted generalized estimating equations.

RESULTS
Five components explained 78% of the total variance. Interleukin (IL)-1β, -2, -4, -6, -8, -17A, -17F, -21, -22 and -23 loaded the highest on the first component, which was associated with increased bone marrow lesions (BMLs) and WOMAC dysfunction score. IL-10, -12 and granulocyte-macrophage colony-stimulating factor loaded on the second component, which was associated with increased cartilage volume, and decreased effusion-synovitis and WOMAC scores. Leptin, adipsin and C-reactive protein loaded on the third component, which was positively associated with WOMAC scores. Resistin loaded on the fourth component, which was associated with increased BMLs and cartilage defects. Apelin-36 and adiponectin loaded on the fifth component, which was associated with increased BMLs.

CONCLUSION
Various inflammatory and metabolic components were associated differently with joint symptoms and structural changes in knee OA, suggesting a complex inflammatory and metabolic inter-relationship in the pathogenesis of knee OA.


The problem of creating a global marketing strategy in today's companies need to address the global problems of the world economy.


Carbon nanotubes (CNTs) are a versatile fundamental building block for classical small scale electronics and quantum electronics, and for the investigation of novel quantum states. However, the ideal properties of CNTs are usually masked by electrical potential fluctuations induced by the substrate. In this context, realization of disorder-free and clean CNT devices with outstanding quality is crucial for the fundamental studies of various interesting phenomena, such as Fabry-Perot interference, Klein tunneling, tunable quantum dots (QDs), spin-orbit interactions, valley spin-blockade, and the formation of Luttinger liquids, Wigner crystals, and Wigner molecules in one-dimensional (1D) systems.

In this PhD project, we introduce a new production scheme, where we combine the two-dimensional (2D) hexagonal boron nitride (hBN) with quasi-1D CNTs. This new approach aims to improve the device quality significantly, and eventually allow us to explore the electronic transport properties of CNTs in extended 1D geometries. In particular, we investigate hBN as clean substrates for CNT QDs, insulators for top finger gates, tunnel barriers to CNTs, and to fully encapsulate the CNTs. Our results are very promising first steps in the fabrication of substrate-bound very clean CNT devices. This allows us to explore many advantageous properties of CNTs in more versatile structures than possible in two-terminal devices with "ultra-clean" suspended CNTs.

This thesis is structured as follows. In Chapter 2, we introduce the theoretical background of the studied material systems, namely, the CNTs and hBN, with a focus on the basics of the CNT QDs. We discuss the superconductivity phenomena that may occur when a CNT is brought into contact with superconductors. Chapter 3 describes the fabrication details of hBN-CNT heterostructures and demonstrates the low-temperature measurement set-up. The main results of this thesis are presented in Chapters 4-7. We investigate the scanning electron microscopy (SEM) imaging contrast for locating CNTs on hBN flakes in Chapter 4. We discuss the low-temperature characteristics of CNT QDs fabricated on hBN flakes and of the dual-gated CNT QD devices with hBN top-gate dielectrics. We demonstrate that very good electrical device quality and stability can be achieved simply by introducing hBN flakes into the system. In Chapter 5, we focus on the CNT devices with atomically thin hBN tunnel barriers. We first characterize a CNT parallel double-QD, where we study the avoided crossings observed in its finite bias spectroscopy. In the second part of Chapter 5, we turn to the discussion on challenges of integrating atomically thin hBN into a CNT device. In Chapter 6, hBN encapsulated CNTs with zero-dimensional (0D) normal metal side contacts are investigated, while devices with 0D superconducting side contacts are characterized in Chapter 7. We demonstrate that low contact resistance with high-yield can be realized with 0D side contacts. This system allows us to study induced superconductivity in hBN encapsulated CNTs, where different transport regimes are identified. In an intermediate coupling regime, we observe Coulomb blockade, quasiparticle transport, resonant Andreev tunneling, and Andreev bound states, while in a strong coupling regime, multiple Andreev reflections and the magnetic field dependence of the critical current are discussed. Chapter 8 summarizes the experimental results and provides an outlook.


Summary I. It was hypothesized that male Ss will project more on situations pertaining to the lives of men than on situations pertaining to the lives of women and that female Ss will project more on situations pertaining to the lives of women than on situations pertaining to the lives of men. II. It was further hypothesized that male Ss and female Ss will not differ with regard to the amount of projection elicited by male and female pictorial figures. Transcendence Indices were used as measures of the amount of projection. Ss were 30 male college students and their wives. Hypothesis I was confirmed for men only. Hypothesis II was confirmed for men and for women.


T. Kohonen has described an algorithm for fitting a k-dimensional grid of points to a set of points taken from a k-manifold in ~n, for k<~n. The algorithm is inspired by a neural model and bears some of the marks of its ancestry. In this paper we show that if the process converges, it converges to a locally 1-1 mapping of the grid onto the manifold. Hitherto this result has only been proved for the case where k= 1. The analytic process of parametrising manifolds is well known to Mathematicians and Physicists, [1] and is becoming increasingly familiar to Engineers concerned with, for example, robot manip-ulator trajectories [2]. The numerical equivalent does not appear to have been much studied, except in special cases. Suppose we have a finite set of points in En and we wish to fit a manifold to them. There are two special cases of note, the first is the case of fitting a 1-manifold, a curve, to a set of points in R 2. We may be concerned with choosing a curve that passes through all the points, as is commonly done with low order splines, or we may suppose there is some random variation and we wish to satisfy some goodness of fit criterion such as least squares, together with some simplicity criterion such as a bound on the degree of a polynomial. The second special case is where we have a set of points in R n and we wish to find the hyperplane of dimension k which contains most of the variation of the data. The well-known Karhunen-Lo~ve expansion accomplishes this last [3], and there are algorithms for the one-dimensional curve-fitting case, and also for the two-dimensional case. In all cases, the manifold is constrained globally by all the data points. The problem of finding the 'best fit manifold', and assessing the goodness of fit, is then a generali-sation (to the non-linear and to higher dimensions) of a standard problem. It is reasonable to want to (a) smooth data, (b) interpolate data and (c) reduce the effective dimension of data, without the constraints on dimension on the one hand or linearity on the other. It is necessary to tackle this problem locally, unlike the case of least squares best fitting of graphs of functions, since the global topology is unknown. We cannot therefore expect to emerge with one function, but must finish with …


Successful implementation of active noise control (ANC) systems is dependent on their practicality. ANC systems that attenuate environmental noise through open windows of urban accommodation should ideally avoid the use of error microphones for the ease of implementation and maintenance. To remove the error microphones, control filters can be fixed by formulating a steady-state equation for various incidences of noise. The trade-off of such a fixed-filter approach, however, is the degradation in noise attenuation performance when the incident noise deviates from the incidence angles used to formulate the fixed filter. Using a multichannel control formulation of tonal disturbances, a fixed-filter formulation is compared with the exact least squares solution in a 2D window finite element method (FEM) simulation. Preliminary results have showed that the full-rank fixed-filter approach can theoretically yield the same attenuation as the exact least-squares method in cases of single incidence and multiple noise incidences, with some exceptions.


The purpose of this study is to correlate chemical compositions and metallographic observations from archaeological artefacts discovered at Virginian Native American sites dated between the 16th and 18th centuries AD and expand the dataset available for this type of material. The compositional analyses were carried out using LA ICP-MS andEPMA, and visual observations were conducted using SEM-EDS and optical microscopy. The presence, absence and types of inclusions in the metal are correlated to the nature of the copper-based metal (native copper, European smelted copper and brass) as defined by chemical composition. In addition, the techniques used to shape the objects have been deduced from metallographic observations and variations in the processes according to the type of the metal have been identified, suggesting that Native American peoples adapted their techniques to the new materials imported by the Europeans.


One of the priorities of the state policy in the field of transport infrastructure development is the modernization of the Russian seaport infrastructure, the creation of modern competitive transport hubs and other architectural objects with a complex functional and planning structure. This article is devoted to the study of functional and technological solutions of modern sea passenger terminals and the requirements to these solutions taking into account the interests of consumers, including people with limited mobility. The functional diagram of the passenger building of the seaport and types of pre-trip passenger training operations are given. It is shown that the efficient decisions of optimizing functional , technological, architectural and planning solutions of seaport passenger terminals is possible with the use of modern IT and technologies for passenger handling. From the perspective of system approach the tasks of functional and technological solutions' optimization are aimed at achieving the high quality of architectural environment and are the mathematical programming tasks.

A search for H line emission, reported to have been detected toward the young star HD 141569A and possibly originating in a clump of planet-forming gas orbiting the star, has yielded negative results. Observations made at the United Kingdom Infrared Telescope and the Subaru Telescope during 2001-2005 covered 11 major transitions of H from 3.42 to 3.99 μm. No H emission lines were detected; one marginal detection at 3.9855 μm in 2002 June was not confirmed in later spectra. The upper limits to the line strengths were significantly lower than the previously reported detections. Supplemental slit-scanning spectroscopy using adaptive optics was performed within 0.″38 of HD 141569A to search for extended emission from H, but no emission was detected. We compare our upper limit to the luminosity in H from HD 141569A with that possible from a gas giant protoplanet and also from a jovian mass exoplanet in close orbit about its central star.


We maintain a one of a kind, large-scale and high resolution (both spatially and temporally) traffic sensor dataset collected from the entire Los Angeles County road network. Traffic sensors (installed under the road pavement) are used to measure real-time traffic flows through road segments. In this paper, we exploit this dataset to rigorously verify two popular instinctive understandings about traffic flows on road segments: 1) each road segment has a typical traffic flow (known by local travelers) and one can often categorize road segments based on the similarity of their traffic flows, and 2) the road segments within each category not only have similar traffic flows but also are similar in their other characteristics (such as locality, connectivity). Toward this end, we developed a hypothesis analysis framework based on a variety of clustering and correlation evaluation techniques and leveraged this framework to respectively show the following. First, the set of road segments can indeed be partitioned into a set of distinct subpartitions with similar traffic flows, and there is a limited number of signature traffic patterns/labels each of which can accurately represent all traffic flows of a subpartition of the road segments. Second, all segments within each subpartition (represented by one signature) are also highly similar in three other characteristics, namely, direction, connectivity and locality. Our experiments verify our observations with high confidence.

The bullwhip effect (BWE) and stochastic demand coexist in supply chain operation management, which leads to a lower performance. In recent years, with the development of blockchain, cloud computing, big data, and other digital technologies (DTs), many enterprises hope to use them to weaken the BWE and improve profits. This paper focuses on improving the application level of DTs in the supply chain through coordination for enhancing the performance. We consider a supply chain with one-supplier-one-retailer and coordinate it with the cost-sharing contract and revenue-cost-sharing contract (the improved contract). We find out that the retailer and supplier did not always have the willingness to use DTs to alleviate the BWE. Even if they have the intention to use DTs, their ideal application level is not the same. After coordination, both the application level of DTs and the performance of the supply chain are improved, and we find that the improved contract has a better coordination effect. Finally, we validate our model by numerical simulation.


Poetry is unique in language expression.Different linguistic,cultural and historic factors have resulted in great difficulties in poetry translation.Generally,a good target text(TT) is faithful to the source one(ST) in content.Nevertheless,a proper target text always takes rhythm and image of source text into consideration.Taking Shakespeare's famous Sonnet 18 as the example,this paper aimed to analyze the feature of E-C poetry translation from the perspective of rhythm and image.


In this paper we present 0-1 integer linear programming models for problems of loading rectangular boxes into containers, trucks or railway cars, considering the practical constraints of stability and load bearing strength of the cargo. The models can also be applied to three-dimensional problems of loading rectangular boxes on pallets, in which the boxes do not need to be arranged in horizontal layers on the pallet. We are not aware of other studies in the literature that present mathematical formulations to these problems considering these constraints explicitly. Computational experiments with the proposed models were performed with the software GAMS/CPLEX and randomly generated instances. The results showed that the models are consistent and they properly represent the situations treated, although this approach (in its current version) is limited to optimally solve only problems of moderate size. However, the models can be useful to motivate future research exploring decomposition methods, relaxations, heuristics, among others, to solve these problems.


The Upland Holistic Development Project (www.uhdp.org), the Thailand affiliate of Plant with Purpose (http://www.plantwithpurpose.org/), has been exploring alternative cooking fuels. Biogas and gasifier stoves hold promise, but UHDP staff members have observed that many of their focus communities are not ready to adopt these specific approaches, partially due to the cost of materials and equipment.

In order to display stochastic video information stably,an external generator for generating video synchronous signals is presented in the paper.Using TMS320F206 as a controller of USB interface chip PDIUSBD12,high data acquisition can be controlled synchronically.From the acquired stochastic video data,PC transfers parameters of synchronous signal to DSP duly through USB interface and DSP processes frequency division coefficients by fuzzy control.As a result,the DSP can generate video synchronous signals with precision 7ps to control the acquisition and display stochastic video signals stably.Successful acquisition and display of stochastic video signals with line-period 15.625kHz and field-frequency 50Hz and the video leaky signals of computer display with line-period 48.656kHz and field-frequency 60Hz respectively demonstrate that this plan is feasible.


A great many festivals are mentioned in the Bible. For the Jews there are seven major festivals, such as the Passover, Pentecost, the Sukkoth (the Feast of Tabernacles) and so forth. For Christians there are Christmas, Good Friday, Easter and Thanksgiving. The Bible does not mention the Mid-Autumn Festival, but there are topics in it related to this festival. The Mid-Autumn Festival is a traditional Chinese festival, the time for reunions of entire families, and when people invariably gaze at the moon and consume moon cakes. I will start with the moon and discuss the Mid-Autumn Festival from the perspective of the Bible.

Bilateral adrenal neuroblastoma (BANB) is a very rare entity. It is more common in young children and has certain clinical features. Patients with BANB have a more favorable prognosis than patients with unilateral adrenal neuroblastoma (NB). The article presents an analysis of 29 cases of BANB in children who underwent treatment at the Dmitry Rogachev National Medical Research Center of Pediatric Hematology, Oncology, and Immunology. This study is supported by the Independent Ethics Committee and approved by the Academic Council of the Dmitry Rogachev National Medical Research Center of Pediatric Hematology, Oncology, and Immunology. The analysis was performed for the period from April 2012 to December 2018. Bilateral adrenal involvement was diagnosed on the basis of analysis/assessment of the results of all relevant imaging and instrumental tests. Additionally, we performed a retrospective analysis of the findings of computed tomography, magnetic resonance imagining, and scintigraphy with 123I-metaiodobenzylguanidine (123I-MIBG). In view of 123I-MIBG scintigraphy sensitivity threshold, and in order to confirm the diagnosis, imaging findings were reviewed by an experienced radiologist. The patients received therapy in accordance with the risk-adapted NB-2004 protocol. Here, we analyzed the details of clinical presentation of the disease, age at the time of diagnosis, time from the disease onset to diagnosis, the presence or absence of life-threatening symptoms (LTS) and adrenal insufficiency, the aspects of patient management (including special aspects of surgical treatment), and treatment results. The median age at the time of diagnosis was 1.9 months. The patients were divided into 3 groups: children with localized BANB; children with true stage 4 disease; children with stage 4S disease. Most patients had metastatic NB, whereby stage 4S cases prevailed (55%, n = 16). Given the low sensitivity of MIBG scintigraphy for the detection of small tumours (less than 2 cm), one should use a comprehensive approach to the assessment of the results of imaging and instrumental tests in patients with BANB in order to confirm bilateral involvement. At diagnosis, about half of the patients with BANB (48%) had clinical symptoms associated with the presence of a retroperitoneal tumour mass and massive hepatomegaly because of liver metastases. Thirty-four percent of patients developed LTS. One of the typical features of BANB was the frequent development of adrenal insufficiency (in 41% of cases) caused by bilateral adrenal involvement, and this should be taken into account when performing diagnostic investigations and providing treatment to patients. Since bilateral radical resection is associated with the inevitable development of adrenal insufficiency, surgical treatment should be determined on an individual basis. Bilateral adrenalectomy is not generally recommended and can be undertaken after an interdisciplinary discussion in case of unfavourable course of the disease (e.g. in case of recurrence). Even if patients with BANB develop certain complications or events (progression) their prognosis is still good. The three- and five-year event-free survival rates in patients with BANB were 86 ± 6.4%. The three- and five-year overall survival rates were 100%. The analysis of patients with BANB showed that they have a more favourable course of the disease, and this may serve as grounds for assigning such patients into a special group. In view of the degree of tumour extension, the specifics of staging, and frequent development of adrenal insufficiency, standard check-ups should be complemented by endocrine monitoring, and surgical approaches should be chosen on an individual basis.

The main aspects of financial planning in the enterprise are investigated in the work. The negative and positive factor impact on the financial success and development of enterprises is discussed. The tools that provide improvement of financial indicators of the enterprise and increase of the general level of their development, including sources of formation of financial resources of the enterprise are defined. The sequence of control over the implementation and regulation of the financial plan of the enterprise is proposed. The main tasks of financial planning are as follows: resource balancing of the cycle of production assets on the basis of self-sufficiency and liquidity of debt obligations, resource provision of social measures; rational allocation of capital; prerequisites for financial stability, solvency and creditworthiness determination of the most rational directions of enterprise development that will provide the greatest profit in the planning period; efficient use of financial resources. Factors of influencing the financial planning of enterprises are: technical and economic; organizational and managerial, political and legal and socio-psychological (social). The source of formation of financial resources of the enterprise for the purposes of financial planning is the investment policy, which determines the mechanisms of investment. Investment mechanisms include: own funds mobilization mechanism; the mechanism of mobilization of borrowed funds and the mechanism of mobilization of borrowed funds. The sequence of control over the implementation and regulation of the financial plan of the enterprise includes: formation of the financial plan (operating budgets) of the enterprise; execution of the financial plan; assessment of the risks of influence on the financial stability and development of the enterprise by groups; conducting an analysis of the implementation of the previous financial plan in accordance with the standards for the balance of indicators of the financial activity of the enterprise; choice of technologies and tools to control the implementation of the plan; detection of the result; Regulatory measures to eliminate "Strategic mistakes". Thus, the financial planning of the enterprise is an extremely important component of successful financial management.


Corrugated web beams made of cold-formed steel components represent an economical solution for structures, offering high flexural capacity and deformation rigidity. For conventional corrugated web beams, made of thick plates for the flanges and thin sinusoidal steel sheets for the web, the elements can be joined by standard bolted end-plate connections. In the case of corrugated web beams made of thin-walled cold-formed steel components only, additional plates are required to accommodate the shape and position of the profiles. A large experimental program was carried out on corrugated web beams made of cold-formed steel elements. One of the objectives was to determine the capacity of these beams and the influence of several parameters on the response of the beam, but also very important were the end connections of these beams. The recordings obtained from the tests were used to validate a numerical model. Based on the validation of the numerical model, finite element analyses were performed to study four solutions for end connections to facilitate assembly, optimise the number of bolts, and increase the capacity and rigidity. Although the connection can be improved for assembling reasons with the presented solutions, the overall capacity is limited by the components subjected to compression that lose their stability. Doi: 10.28991/CEJ-2023-09-04-01 Full Text: PDF


A new energy-recovery sustaining driver for an AC plasma display panel (PDP) is proposed. Since it has only one auxiliary switch compared with the four of the prior circuit, its size and cost can be greatly reduced. Moreover, it features the fast transition time of the panel polarity, fully charged and discharged PDP and soft switching of all power switches.


Plant growth and development are coordinalely controlled by several internal factors and environmental signals. To sense these environmental signals, the higher plants have evolved a complex signaling network, which may also cross talk with each other. Plants can respond to the signals as individual cells and as whole organisms. Various receptors including phytochromes, G-proteins coupled receptors (GPCR), kinase and hormone receptors play important role in signal transduction but very few have been characterized in plant system. The heterotrimeric G-proteins mediate the coupling of signal transduction from activated GPCR to appropriate downstream effectors and thereby play an important role in signaling. In this review we have focused on some of the recent work on G-proteins and two of the effectors, PLC and PLD, which have been shown to interact with Gα subunit and also discussed their role in abiotic stress tolerance.


In this paper, we present a compact model for semiconductor charge and quantum capacitance in III-V channel FETs. With III-V being viewed as the most promising candidate for future technology node, a compact model is needed for their circuit simulation. The model presented in this paper addresses this need and is completely explicit and computationally efficient which makes it highly suitable for SPICE implementation. The proposed model is verified against the numerical solution of coupled Schrödinger-Poisson equation for FinFET with various channel thickness and effective mass.


I offer an ethnographic analysis of two "theory" classes in an elite American literary studies program. First, I examine the classroom's bureaucratic form, as it is structured by power, time and space, and made visible in syllabi and attempted pedagogical reforms. I then turn to pedagogical practice, examining the forms of knowledge and power implicit in classroom discourse. I show that ideological stances toward theory vary according to individual status in the theoretical field. I consider the epistemic fetishism of the "text" within classroom knowledge‐making practices. Finally, I draw out some implications of my analysis for reflexive academic research, with particular attention to Bourdieu's reflexive social science.


Major changes have been taking place in social care throughout the UK, resulting in new and complex responsibilities for an estimated third of a million of social services staff. Drawing on extensive survey material, this book explores the work histories of social services staff, describes their current jobs and examines their work experiences.


Analytical calculations based on a Landau Level (LL) picture are reported for an interface (with a finite-width Quantum Well (QW)) and for a fully three-dimensional charged quantum electronic system in an external magnetic field. They lead to a sequence of previously unnoticed singular features in global magnetization and magnetic susceptibility that lead to nontrivial corrections to the standard de Haas - van Alphen periods. Additional features due to Zeeman splitting are also reported (such as new energy minima that originate from the interplay of QW, Zeeman and LL Physics) that are possibly useful for the design of quantum devices. A corresponding calculation in a Composite Fermion picture leads to new predictions on magnetic response properties of a fully-interacting electron liquid in a finite-width interface.


Virtual strategic games are more and more often used teaching tool, their use lets to follow the current trends in didactic study. However, games are still an innovative tool which indicates the necessity of discussion on possibilities of their implementation in entrepreneurial education. Virtual strategic games seem to be available for exploration also as a research tool which explores a kind of an experiment or quasi-experiment to conduct research on entrepreneurship. In economic science, the possibility to use the experiment as research tool is very limited as it should be used on real companies or economies. Meanwhile, strategic games being a form of running a business in a virtual environment, not in real one, seem to give research advantages connected with the possibilities of observing the behaviour and its effects of business activities without the risk and costs of experiments born by a real company. The aim of the paper is to assess the possibilities of using the strategic games in entrepreneurial educa- tion and experimental research in entrepreneurship. Theoretical discussion is supported by the results conducted during the virtual strategic games. To assess the research potential of games, the example of entrepreneurial orientation was explored and the results of survey and experiment on the same sample of students were compared.

In view of limited information, an attempt has been made to work out the distribution pattern of arsenic (As) between root and shoot of high and low grain-As accumulating rice cultivars (HAC and LAC, respectively). For this purpose, a solution culture experiment was conducted at ICAR-Indian Agricultural Research Institute, New Delhi during kharif 2018-19 with two doses of As (@ 0 and 100 µg/L) and four rice cultivars comprising one HAC (IR-36) and three LACs (Khitish, Satabdi and Badshabhog). Results indicated that the biomass yields were not affected either by As or by cultivars. The highest root As content was recorded with Khitish (4.64 mg/kg), whereas, IR-36 showed the lowest value (2.00 mg/kg) but shoot As content did not vary with cultivars. Cultivars followed almost similar trends for As uptake. The highest translocation coefficient of As from root to shoot ranged from 0.52 (IR-36) to 0.31 (Khitish). It is clear from the study that LACs are more efficient in storing As in root, even though they uptake higher amount of As at the initial phase of growth, whereas, As is mobilized from root to above ground parts more efficiently in case of HACs. Thus, partitioning of As between root and shoot appears to be an important characteristic of rice (Oryza sativa L.) cultivars responsible for differential accumulation of As.


Stabilizability and asymptotic stabilizability of switching systems is characterized in terms of the existence of controlled invariant sets and domains of attraction. Then the classical Kalman decomposition for linear dynamical system is extended to switching systems. This shows that the core issue for solving the stabilizability problem for switching systems is the stability of an autonomous (i.e. without continuous input) switching subsystem. keywords: Switching systems, stabilizability, Kalman decomposition


Many community colleges are considering changes in their traditional semester calendars. In California, the most common question facing colleges is whether to switch from the traditional (in California) 18-week semester to a 16-week one. Unfortunately, little information is available regarding how a calendar change affects students. This paper details the results of a student and faculty survey conducted at a small community college in central California on the compressed calendar and related issues. Survey results are discussed and the two survey instruments are included as appendices. Future research in this area is discussed as well. Introduction Many community colleges are considering amendments to their traditional semester calendars. This is particularly true in California, where unique funding rules for colleges provide an incentive to change. The most common change is for colleges to switch from an 18-week semester to a 16-week one, increasing the number of minutes students spend in class each week so that the same amount of time (or more) is spent on instruction in fewer weeks. Various names are used for revised calendars such as "alternative" schedules or "compressed calendars". There are also many options being considered in various community colleges, such as offering halfsemester length courses. Through the remainder of this paper, I will use "compressed calendar" to refer to the conversion from 18 to 16-week semesters. There are many issues that must be considered when making such a change. Among these are: • Semester start and end dates • Class start and end times 1 Presented at the Research and Planning Group (RP Group) of the California Community Colleges 40 annual conference, May 1-3, 2002. The author would like to thank Ron Glahn and the entire Porterville College Compressed Calendar Committee for their contributions to this paper. 2 Michael Carley is the Director of Institutional Research at Porterville College. He can be contacted at Porterville College, 100 E. College Ave. Porterville, CA 93257. Email: firstname.lastname@example.com; Phone: 559-791-2275. 3 A detailed analysis of the funding issue is beyond the scope of this paper. In brief, many colleges have learned that by shortening the length of the semester from 18 weeks to 16 weeks and lengthening the amount of class time per week, the state funding formula will provide them with additional Full-Time Equivalent Students (FTES) without increasing the number of students taught or adding courses. Funding in the state is based on FTES, so this increase means additional funding for the college.


Tailored to address the lack of communications systems between bus and bus stops, this paper explores the use of IEEE 802.11p, a form of Dedicated Short Range Communication (DSRC), for communication in a Bus Rapid Transit (BRT) system using MATLAB through modification of an existing application Vehicle Ad-Hoc Network (VANET) Toolbox. Adding a bus mobility model and a bus entity, a Bus-Following model (BFM) is employed within a single lane setup following the BRT system. Multiple test simulations were conducted, varying in number of buses, bus stops, and information messages. Graphical representations of the communications as well as the generated information messages show that the system works according to the intended design. The simulator was also tested to the scale of a major Philippine road using the latest available passenger inflow and outflow data. The results show that communications between bus and bus stops were within acceptable parameters for latency and Packet Delivery Ratio while also showing that a bus to bus stop ratio of 2:1 was not sufficient to handle the passenger flow of EDSA during the 7AM rush hour. Overall, a verified simulator within the open-source VANET Toolbox is presented.


Charting Nicholas Remisoff's artistic legacy during his California period, this essay explores his contributions to the cultural landscape of the state and emphasizes his work on live stage productions in San Francisco and Los Angeles in the early 1930s and 1940s. Delineating the critical reception of Remisoff's work in opera, ballet and theatre in these cities, this essay also highlights the artist's interactions and key collaborations with other Russian and European emigre artists and reflects on the nature of Remisoff's particular affinity with Southern California.


As an important topic in research, Inner-vehicle communication (IVC) network gets more and more attention. But a lot of research ignored the effect of the relative speed between the vehicles of the communication performance in bidirectional traffic streams when they set multichannel traffic flow scenes. In order to solve the problem we studied the changes of each performance on different relative speed of the traffic streams. The simulations were conducted in network simulator 2(NS2), simulation of urban mobility(SUMO) and MOVE platform, we changed the velocity and acceleration of the vehicles in different lands and study the throughput, average end to end delay and hops. The simulation results showed that the relative speed of the bidirectional traffic streams affect performance of the IVC network actually. The research can help to configuration related parameters and set scenes in right way, so that to improve the reliability and efficiency and security of IVC network.

In addition to primary constituents such as proteins, fats and carbohydrates, cacao produces a variety of chemicals that often influence the consumer. Cacao is most well-known for its methylxanthine alkaloids, theobromine and caffeine. These compounds interfere with adenosine receptors, thus having noticeable effects on mood and alertness. Cocoa flavanols are associated not only with their antioxidant potential, but also their ability to lower blood pressure and improve mental processes. Possible synergistic and antagonistic effects among these main phytochemicals and others, such as amines and endocannabinoids, are also discussed.


The design emphasis of indoor environment usually lies in the unity of aesthetics and practicability, and the scientific selection of architectural decoration materials is the basis to create a superior indoor environment. In recent years, with the addition of new technology, new materials and design concept has been constantly updated, in the interior environment design reasonable collocation, choose decorative materials, make the best use of material, become an important factor to ensure the quality of interior decoration. Therefore, this paper studies the application of several new architectural decoration materials in indoor environment. 1. Overview of New Decorative Materials In recent years, urban and rural construction industry is gradually expanding in scale, facing the new situation and the situation of various design technology related to architectural design has also achieved a certain degree of improvement and optimization. In the process of specific architectural decoration design, the new material has its unique advantages of environmental protection, which is more suitable for the current field of architectural decoration. Compared with the traditional materials, the new building decoration materials have the advantages and characteristics of energy saving and environmental protection, and also help the whole building decoration project to save consumption cost. More designers have gradually embraced and embraced today's new materials as technology has evolved, and have begun to try to apply them to interior design. Therefore, the designers should make clear the development advantages and basic characteristics of the new materials, and choose the decorative materials that meet the design requirements based on the actual design situation. Nowadays, the new decorative materials used in the field of architectural decoration in China mainly include environmental protection materials, artificial crystal and glass materials. To improve and optimize architectural decoration design, the most important thing is to do a good job of material screening, choose new decorative materials as support, save cost and improve efficiency. And the new materials also have the advantages of technology diversification and the characteristics of green environmental protection, in line with the basic requirements of environmental protection and energy-saving architectural design. In addition, designers need to choose appropriate new decorative materials according to local conditions to optimize the design results [1]. Figure 1 Architectural decoration 2020 7th International Conference on Civil Engineering, Materials and Chemistry (ICCEMC 2020) Copyright © (2020) Francis Academic Press, UK DOI: 10.25236/iccemc.2020.025 115 Comparing the traditional decorative materials with the new materials, it can be found that the new materials have the characteristics of green and environmental protection. The performance of the new material is more durable, and its performance will not be reduced after a long time. In recent years, in the current stage of architectural decoration more applied to 3R new materials, this type of materials have the characteristics of repeatable, recyclable, renewable, and will not bring harm to the human body, very consistent with the harmless building purpose. And this type of material also has the green environment, close to the natural characteristics of the times, the rational use of such materials to design a healthier and more comfortable new indoor environment, which is very consistent with the basic needs of urban and rural people nowadays. With the development of economy and technology, the construction industry is expanding its coverage in urban and rural areas. In the new situation, more residents will choose new decorative materials which are more environmentally friendly, and architects and manufacturers will be more inclined to use green materials to some extent. Under the influence of today's green environmental design concept and design objectives, the new materials without pollution, pollution and radiation will be more favored by the majority of owners, continue to promote, and will gradually build up the people's livelihood project. Therefore, in the design of indoor environment, it is necessary to actively apply and popularize the characteristics of green environmental protection of new materials on the basis of conforming to the design purpose of the new period. Figure 2 Interior design 2. Types of New Materials In recent years, many new materials have achieved good results in the field of architectural decoration, among which the most typical new types of materials are as follows: first, synthetic ecological wood. This new type of material contains resin, wood fiber, polymer material and other specific components, so this type of material has a better visual effect, the overall performance of the stable material structure and heavy wood sense. Compared with the traditional building wood, this new type of wood has better waterproof, heat insulation, anticorrosion, heat insulation and other comprehensive properties, at the same time, it also has the key performance of fire protection [2]. In the concrete construction, the buckle type steel keel can be arranged inside the ecological wood. In recent years, many commercial buildings, recreational places and landscape design in the interior environment will be inclined to choose eco-wood. Second, when decorating the wall will choose art paint. Many designers in the design of interior wall materials will use art paint to decorate the entire wall, which is very conducive to the indoor environmental style fully displayed, and in line with the environmental protection, green design purpose. Art paint from Europe, with good dustproof and waterproof performance, not only will not cause harm to the human body, due to its various texture features, to a certain extent, but also conducive to increase the texture of the wall and luster, eliminate wall radiation. It can be seen that the defects of the poor gloss in the wall design in the past can be effectively compensated and perfected by the new architectural decoration materials. There are two types of art paint, real stone paint and diatom mud, which are used in interior environment design.[3]. Third, GRG new type materials. New GRG materials are used in interior design and typically represent a gypsum board made of fiberglass. Compared with this new type of decorative material, traditional plasterboard lacks some comprehensive performance, and adding

This study investigated the effects of using different mixing fluid samples, potable water, fermented locust beans and sewage, on the strength properties of a self-healing concrete. The physicochemical characteristics of the mixing fluid samples were determined before investigating their effects on the strength development of the resulting concrete samples. The strength parameters investigated comprised of the compressive strength, split tensile strength and flexural strength. It was found that for each of the concrete samples cured for 3, 7, 14, 21 and 28 days, the samples produced with fermented locust beans had the highest compressive, split tensile and flexural strength values, followed by those produced with sewage, while the concrete made with potable water had the least strengths for the Grade 20 concrete samples produced. The activities of the bacteria in the mixing water samples containing fermented locus beans and  sewage, aside having the potential to seal cracks that develop within the concrete, also increased the strength properties of the resulting concrete.


We show that in reflexive Banach spaces there are two classes of closed cones (consumption sets) i.e. cones whose any budget set is bounded and cones whose any budget set is unbounded. We prove that in the first category of these cones the demand correspondence of any upper semicontinuous preference relation exists and we show also that this property characterizes the reflexive spaces. Moreover we prove that in this class of cones, the demand correspondence of any convex, continuous preference relation is upper hemicontinuous. To prove these results we use some tools from the theory of Banach spaces. JEL Classification numbers: D500, D510.

Aggregation-induced emission (AIE) compounds, dye2 and dye3, with a rotatable N–N single bond and aza-crown-ether, have been synthesized. The fluorescence intensities of both dyes are very weak in THF, while become extraordinarily strong in a mixture of H2O–THF (v/v 95%). They are increased by 88.9 and 70.7 times, respectively, indicating enhanced blue-green fluorescence emissions. The λem of these two compounds in different states has been well studied. Besides this, dye1 and dye2 were characterized by single crystal X-ray structural determination. The results show that molecular interactions are formed in the particles, which considerably restrict the intramolecular vibration and rotation.

amplify the question at issue and to review the arguments pertaining to it for the Bulletin. As I see it, the question at issue may be formulated as follows : Does the principle of tax capitalization allow certain persons to enjoy tax exemption to the relative disadvantage of other persons in the tax community? What is meant by tax capitalization? This may be made clear by an example. If a parcel of land is expected to bear $400 in rent for a long number of years, and if four per cent is the rate of income earned in land investments, the price of this parcel of land will be $10,000. The price is the capitalized value of the expected income. If, now, a yearly tax of $100 should be levied on this land, the net rent would thereby be decreased to $300, and this income at four per cent would be worth only $7,500; or, putting it differently, the tax of $100 per year capitalized at four per cent amounts to a present worth of $2,500, and this being deducted from the $10,000 value leaves a value of $7,500. Thus the tax is capitalized and deducted from value ; or, briefly, it is capitalized. If now the land be sold, the new buyer pays the $100 tax yearly, but as he continues to receive $400 rent he enjoys a net rent of $300, which is all that he paid for. Hence, the tax does not burden him. He is exempt from this tax through tax capitalization. This principle holds true on any good whose value is determined immediately by the capitalization of the expected income, but it does not apply " to virtually every form of durable property," as Professor Adams says; * for, regardless of durability, if the good may be duplicated and if the market calls for additional


Cumulative stress energy in active seismic regions caused by tectonic forces creates various earthquake precursors. This energy transformation may result in enhanced transient thermal infrared (TIR) emission, which can be detected through satellites equipped with thermal sensors like MODIS (Terra/Aqua) and AVHRR (NOAA). Satellite time-series data, coupled with ground based observations, where available, can enable scientists to survey pre-earthquake signals in the areas of strong tectonic activity. This paper presents observations made using time series MODIS and NOAA-AVHRR satellite data for derived multi-parameters including land surface temperature (LST), outgoing long-wave radiation (OLR), and mean air temperature (AT) for the moderate, 5.9 magnitude earthquake, which took place on the 27th of October, 2004, inthe seismic region of Vrancea, in Romania. Anomalous thermal infrared signals, reflected by a rise of several degrees celsius (°C) in LSTs, and higher OLR values were seen several days before the earthquake. AT values in the epicentral area also increased almost two days prior to the earthquake and intensified three days after the main shock. Increases in LSTs and OLR disappeared three days after the main shock. The survey and joint analysis of geospatial and in-situ geophysical information on land surface temperatures and outgoing long-wave radiation provides new insights into the field of seismic hazard assessment in Vrancea, a significant area of tectonic activity in Romania and Europe.

Manufacturing firms are getting more global and forming global supply chain networks to pursue lower production costs and emerging markets including Asia. The global supply chain network consists of domestic as well as international suppliers, factories and markets. Then, the supply chain network applies customs duties when parts and products are transported across overseas borders. Additionally, several treaties of customs duty such as Free Trade Agreement (FTA) and Trans-Pacific Partnership (TPP) are unavoidable for designing the global supply chain network.On the other hand, current fluctuations of oil and energies price cannot be ignored for the global supply chain network. This study analyzes influences by fluctuating the material prices on the global supply chain network with the customs duty and TPP. Firstly, the global supply chain network with customs duty and TPP is modeled. Next, the model is formulated with integer programming. Finally, sensitivity analysis is conducted in order to investigate the effect on the global supply chain network by fluctuations of material prices.

as mecânicas. Os testes estatísticos aplicados aos resultados permitiram concluir que os produtos obtidos por "ausforging" apresentaram a melhor combinação de resistência mecânica e superficial dos produtos forjados, sem a forjamento. Abstract Hot forging of microalloyed steels, also known as high strength low alloy steels (HSLA), has a wide application for manufacturing automotive components. The purpose of this study was to evaluate the microstructure and the mechanical strength and toughness of the 27MnSiVS6 microalloyed steel, when formed by ausforging, to analyze the process performance and the quality of products. Ausforging was compared to both hot and warm forging processes. As a result, considering the tensile, fatigue (under rotating bending) and the fracture toughness tests, the best mechanical properties were shown by the ausforged products. Statistical analyses revealed that products obtained by ausforging presented the best combination of strength and surface quality, without increasing the forging load.
