TM, electromagnetic scattering from a perfectly conducting wedge with a cylindrical tip is formulated using a mode-matching technique. The eigenmode expansion is then written in a convenient form, where the total field is expressed as a superposition of a wedge-diffraction term based on the uniform theory of diffraction, a geometrical optics term, and a Correction Field term due to the presence of the cylindrical tip. The obtained diffraction coefficient can be easily incorporated into existing ray-tracing, high-frequency codes for the prediction of scattered fields from electrically large structures. The underlined formulation and obtained expressions are verified by comparing numerical results with the finite element method.


Recent reports have shown that the Nonylphenol (NP), a well-known toxic environmental chemical has adverse effects on sperm in different species. Therefore, the current study was aimed to determine the deleterious effect of NP on frozen-thawed bull sperm. Sperm were exposed to different concentrations of NP (1, 10, 100, 250 and 500 μg NP/mL) dissolved either in DMSO or Ethanol and incubated for 4 h at 37oC. Sperm parameters were assessed at 0, 1st, 2nd, 3rd, and 4th h of incubation. Both percent motility and mitochondrial membrane potential (MMP) of sperm have decreased significantly (P<0.05) at dose level of ≥ 250 μg NP/mL. Acrosome reaction was induced (P<0.05) even at minimal dose concentrations of 1μg NP/mL (P<0.05). However, the percentage of acrosome reacted sperm increased (P<0.05) with increase in dose level. In conclusion, NP impairs the sperm characteristics by adversely affecting motion kinetics, mitochondrial membrane potential and inducing premature acrosome reaction in bovine.


During the recent small-pox epidemic in Western Pennsylvania, and particularly in Pittsburgh, which through the effective administration of the Department of Health was quickly circumscribed and subdued, the Physicians of our vicinity had an unusual opportunity to observe large numbers of vaccinations. It has been estimated that in Pittsburgh about one-third of the population was vaccinated. The ordinary vaccination with cow-pox creates little interest in the mind of the practicing physician, and the results are not carefully observed. There is one phase of this topic, however, which is very interesting, and while mention of it is made in the recesses of the English literature, I think that it is not presuming too much to say that it is not generally recognized, and that its explanation is almost unknown. A patient is vaccinated and after a slight redness or perhaps a small raised papule lasting one to three days the entire


It has been established that the graft of cryopreserved dermal fibroblast is able to improve wound healing. Transplantation of mesenchymal stem cells has the ability to undergo site-specific differentiation and participates in wound healing process. The wound healing process requires angiogenesis and the formation of a vascular network throughout the newly formed tissue. In this study we examined the effect of xeno- transplantation of fresh human mesenchymal stem cells and dermal fibroblasts on the angiogenesis. Human mesenchymal stem cells and human fibroblasts were isolated from bone marrow and dermis of the same patients and were grown in culture respectively. We have developed a porous polyethylene disc as an experimental model system for angiogenesis. Single block of polyethylene was cut into discs which were 5mm in diameter and 3mm in thickness. Four discs were soaked in a solution containing 4×cells and 1 ml thrombin. After porous polyethylene discs were loaded with the cell-thrombin composite, they then were coated with fibrinogen. After the discs were cleaned from surrounding fibrin, they were implanted in the back of Sprague-Dawley rats. In group I, the discs were filled with fibrin alone without cells. In group II and III, the discs were loaded with fibroblasts and mesenchymal stem cells respectively. Eight rats and 16 discs per group(total 48 discs) were used in this study. After creating 6 pockets in the back of a rat, 6 discs(2 discs per group) were implanted. At three different time intervals from 1 to 3 weeks, the implanted discs were harvested and processed for histological study. A longitudinal section was cut with a thickness of 6 micrometers in the very middle of a disc. Histological study was carried out to examine the formation of microvessels in the implants. Microvascular density was measured by counting the number of microvessels in the very middle of a biopsy specimen under 100 magnification field. Only fibrinoid materials and inflammatory cells were detected in most of specimens in the first week under 100 magnification field of the very middle. There was no significant differences in microvascular density among the three groups. In the second week, extracellular matrices including microvessels were detected in all the 3 groups. The microvascular density of group III(17.75/ 100 magnification field) was significantly higher than that of group II(10.50/100 magnification field) and group I (10.25/100 magnification field). The third week specimens showed that most of the pores of the implants contained extracellular matrices. Significantly greater differences were seen in the microvascular density. The microvascular densities averaged 52.88, 26.12, and 17.50 per 100 magnification field for group III, II, and I respectively. The results indicate that transplantation of mesenchymal stem cells and dermal fibroblasts can significantly improve the angiogenesis in the wound healing process and mesenchymal stem cells are superior to dermal fibroblasts.


The issue of tax reform in European countries is examined here by Luigi Bernardi. The paper describes the main features of revenue trends and tax reforms in the Nineties. It notes that tax convergence has so far been rather limited and that persisting divergences in tax systems prevent the efficient working of the single market, as the movement of goods, people and capital is still subject to tax interference. The paper concisely surveys the literature concerning the effects of taxation on growth concluding that high tax wedges on labour and high tax rates for corporations may contribute to the European declining growth rate and increasing unemployment. Bernardi argues that tax cuts on labour and corporate capital should be large and well targeted. Given the budgetary constraints set by the Stability and Growth Pact and the difficulty of cutting spending, the main feasible policy option is that of shifting part of the tax burden to consumption, rents and environmental externalities. The author also argues that reforms should pay greater attention to equity issues both in vertical and horizontal perspectives. The tax system should contribute to ensure equal opportunities and should support human capital formation.


We sketch an SU(5) bulk model in 4+1‐dimensions that plausibly produces an effective 3+1‐dimensional standard model dynamically‐localized on a domain wall.


Due to diverse applications in the fabrication of high efficiency perovskite solar cells, organic-inorganic hybrid perovskite have been extensively studied in recent years. In this reported work, thin films of methyl ammonium lead iodide (MAPI) were deposited on the ITO substrate using one-step spin coating method and then annealed at different temperatures from 600C to 900 C at a step rate of 100C. X-ray diffraction (XRD), energy-dispersive X-ray spectroscopy (EDX), Field emission scanning electron microscope (FE-SEM), UV–visible spectroscopy and IV characterization have been employed to characterize the samples. SEM characterization revealed the needle like morphology of MAPI in all films and the surface coverage of substrate. At higher temperatures needle like morphologies completely covered the substrate surface. EDX measurement analyzed the atomic concentration in the grown sample. The XRD patterns of all films revealed the formation of tetragonal phase and no peaks were observed related to doping or impurity phases. The optical properties of all films have been analyzed by absorbance measurement. The increase in the annealing temperature a slight increase in the absorbance study has been observed.  I-V performance of the films greatly depends on the film morphology, which in turn in contingent on the deposition method. In the present work, the annealing temperature which is essential to convert the deposition solution into the MAPI had been change over a range from 600C-800C. It is found that the conversion needs appropriately high temperature to confirm the evaporation of solvent and the crystallization of the MAPI. As well the upshot of the annealing temperature on the film formation morphology and configuration is examined and correlated with the I-V performance.


We consider a model for substrate-depletion oscillations in genetic systems, based on a stochastic differential equation with a slowly evolving external signal. We show the existence of critical transitions in the system. We apply two methods to numerically test the synthetic time series generated by the system for early indicators of critical transitions: a detrended fluctuation analysis method, and a novel method based on topological data analysis (persistence diagrams).


Background Thirty-four percent (265/781) of Multiple Myeloma (MM) clinical trial participants at one cancer center are African Americans (AA). AAs make up only 4.5% of clinical trial participants nationwide, even though MM is the most common hematological malignancy in AAs. Many challenges prevent AAs from enrolling in trials, including mistrust in providers. This study examines if such barriers exist at a high-enrollment cancer center and if not, how they were overcome.


Abstract There has been much interest on achieving educational and research goals by the use of mobile robot platforms. However these platforms are not usually composed by industrial of the shelf solutions. This paper presents the kind of industrial sensors that can be used in an autonomous mobile robot. The vehicle is supposed to follow a track, make choices on its way respecting visual indications of traffic lights, navigate inside a tunnel and park inside a given area. The original part about this AGV is the implementation by use of available industrial equipment rather than the common PC and/or PICs combination.


Role engineering is a both necessary and critical topic in the development of Role Based Access Control system, which seems to be the most proficient access control approach nowadays. Even if the maturity of the RBAC model has been already achieved, the role engineering process is not a standardized approach. The paper aims to illustrate an enhanced process model for role engineering. The model is focused on the intuitive discovering of the roles and their assignment with permissions, using a test-driven approach.


Abstract A second rotation forest sand (Mt Burr sand) was separated by a combination of dry sieving and winnowing into different particle sizes rich in either soil or organic matter. These fractions were analysed for % loss on ignition, % organic carbon, total organic nitrogen and mineral nitrogen. Mineralization of soil organic nitrogen and nitrification of ammonium sulphate added to these fractions were studied. Amongst the heavier fractions obtained by sieving, the <125 μm fraction (the finest) contained the highest concentration of organic and exchangeable nitrogen and was the most active in nitrogen transformations. Amongst the lighter fractions obtained by winnowing, the 125 to 500 μm fraction had the highest organic nitrogen content but mineralization of nitrogen was greatest in the 500 to 2000 μm. Nitrification of native and applied ammonium nitrogen was similar in both the 125 to 500 μm and 500 go 2000 μm organic matter fractions.


Law Number 5 of 1960 concerning Basic Regulations on Agrarian Principles (UUPA) is widely praisedas the great work of the Indonesian nation which is revolutionary and responsive, combining good elements between individualism and communalism. However, the unachieved objectives of the UUPA is hard to deny and the majority of the defense of its failure tends to be normative and ideological. This paper aims to bring the study of the UUPA to a more empirical direction by using theories of public policy implementation, as introduced by Grindle (1980) about content variables and policy contexts, and the theory of critical implementation researchers who use a bottom-up perspective and highlight the actions of implementing bureaucrats. The research used qualitative methods through the study of literature and focused on executive policy, bureaucrats' actions and the context that surrounds them. The study found that the executive policy with the issuance of Presidential Regulation of the Republic of Indonesia Number 86 of 2018 was precisely not in line with several provisions of the UUPA. The presidential regulation has a paradox, wants to accommodate many variables but is confused about the main purpose of agrarian reform. As a relatively top-down policy, the implementation of the UUPA requires the existence of a dominant actor. However, the actions of implementing bureaucrats have long reduced the purpose of the law to merely being an act of legalization of accounting transactions for land that are running according to market mechanisms. Now, the increasing number of Indonesians living in urban areas makes the issue of land more complex, related to land use change and various challenges of sustainable development.


This paper covers wire bonding and molding process development for 50 /spl mu/m fine pitch wire bond plastic ball grid array packages (PBGA). Since a large percentage of the total bonding area was damaged during probe testing, the adhesive strength of the ball bond was reduced. Bond lift issues have been observed after destructive wire pull test. A comparative study of different probe mark size using 0.9 mil wire diameter was presented and analysis on bonded units concludes that the critical damage threshold was around 20% of bonded area. A possible solution with irregular elliptical ball bonding was proposed to improve the adhesive strength of ball bonds. On the other hand, reduced wire diameter has decreased the bending strength of bonded wires significantly, and thus causing serious wire sweep after transfer molding. Experiments were conducted to evaluate wire length with 0.9 mil diameter gold wire. The results show that the wire threshold length is about 4.1 mm. A novel solution was applied using a non-sweep method. The wire length could be extended to 5.0 mm within 1.0% wire sweep. Reliability tests conducted showed that all the units passed 1000 temperature cycles (-55/spl deg/C/spl sim/125/spl deg/C) with JEDEC moisture preconditioning at level 2a (60/spl deg/C/60% relative humidity for 120 hours) and 3 times reflow (peak temperature at 220-225/spl deg/C). It is believed that this solution can efficiently overcome the risk of wire shorting and improve the yield of ultra fine pitch wire bonds in high volume production.


AbstractIt used to be thought that addition of carbon to Fe–Cu compacts inhibited compact growth by reducing solubility of copper in iron, but this effect is in fact slight. The theory that formation of Fe–Cu–C ternary liquid phase promoted shrinkage by liquid phase sintering has also been discounted. It has more recently been shown that carbon additions reduce growth by preventing boundary penetration of iron by copper. The present study verifies the importance of the proportion of high and low dihedral angles which the copper phase forms with γ-iron: carbon inhibits compact growth by causing these angles to increase.

5, 3', 4'-Trihydroxy-6, 7-dimethoxyflavone and 5, 4'-dihydroxy-6, 7, 3'-trimethoxyflavone were synthesized and identified with cirsiliol and cirsilineol obtained from Cirsium lineare SCH. BIP.


Discusses the preliminary simulation results concerning the coverage of realistic bridging faults, according to an experimental fault classification of node shorts between logic nodes. There is evidence to support that, prior to simulation, difficult to detect faults can be identified, according to their topological characteristics. This may allow the definition of manageable subsets of bridging faults, whose avoidance by layout reconfiguration may be rewarding.<<ETX>>


and fragment figures may be due to breakagefusion-bridge cycles rather than an inversion. This is suggested by the U-shaped fragments and the second division bridge and fragments. The present technique does not allow detailed examination of pachytene figures which may or may not reveal inversion loops necessary for positive identification of an inversion. Fragmentation exists in two clearly defined forms. The extreme form of fragmentation results in complete meiotic failure. The less extreme fragmentation of one or two fragments per pollen mother cell apparently does not disrupt meiosis but produces pollen with chromosome deficiencies. It is possible of course that some of these fragments arise from bridge and fragment figures in which the bridge has broken, but are far too numerous for this to be considered the only cause. The circle and catenated ring configuration indicates that two of the seven clones showing metaphase I figures are heterozygous for a reciprocal translocation. One metacentric and one submetacentric tetrad are involved in the translocation. It is interesting to note that the chromosomal aberrations of two types of fragmentation and bridge and fragment figures as reported here in P. peltatum are strikingly similar to those found in Paeonia californica and brownii as recently reported by Walters (1956, 1958). There are certain limitations in the data presented in this paper. The critical anaphase and telophase stages do not occur in sufficient numbers for an accurate indication of aberration frequency. A detailed study of the aberrations, especially in the earlier meiotic stages is also necessary for more accurate data. A more detailed description of the chromosomal aberrations of Podophyllum peltatum will be presented in future papers.


The network routing problem is an important problem to consider behaviors of multiple transportations on a traffic network. This study focuses on the optimal routing problem whose objective is the cooperative and optimal assignment of flows to paths on the network routing. In the optimal routing problem, the amount of flow passing through each path is designated as the decision variable. Therefore, it is difficult to obtain the optimal solution of the optimal routing problem in large-scale networks with a vast number of paths in a realistic time. In many cases, flows pass through a few part of the paths only and no flow passes through other paths in the optimal solution of the optimal routing problem in large-scale networks. If some of paths which are zero-flow paths in the optimal solution can be removed from the decision variables in advance, the efficiency of the optimal routing search is expected to be improved. This study proposes a new solution search method to improve the efficiency of the optimal routing search by removing redundant paths which can be detected in advance by considering a condition with respect to the optimal solution. The effectiveness of the proposed method is confirmed through numerical experiments.

A microwave frequency comb (MFC) with hundreds of measurable harmonics is superimposed on the DC tunneling current in a scanning tunneling microscope by focusing a mode-locked ultrafast laser on the tunneling junction. Two methods for carrier profiling of semiconductors by hyperspectral measurements with the MFC are considered. The first method, analogous to scanning capacitance microscopy (SCM), would require high-precision measurements because resonant detection, required in SCM, is not practical with the MFC. The second method, analogous to scanning spreading resistance microscopy (SSRM), is more sensitive to the carrier concentration and shows promise for achieving sub-nm resolution which is needed by the semiconductor industry with sub-10 nm lithography.


DESCRIPTION: The general model of Thurstone's law of comparative judgment leads to the construction of a unidimensional scale by use of variability-type data collection procedures, e.g., paired comparisons [ 4]. The model is particularly appropriate when the user does not have a physical continuum available but still wants to develop an interval scale from data that originally represent order-type comparisons. A program has been developed from a special case of Thurstone 's law, Case V [ 1] . Thurs tone's Case V procedure permits the user to develop interval scales from the frequency of choices of one stimulus over another and thus to give a quantitative value to differences among scale values. Thurstone's law relies on subjective "confusions" regarding a subject's judgment of which member of a pair of stimuli, e.g. brands, possesses more of some designated characteristic. The proportion of times one stimulus is judged better than another is assumed to be related functionally to how far separated the modes of the two discriminal processes are, the dispersion of the discriminal processes, and their correlations. By assuming that (a) the discriminal dispersions are equal and (b) the correlation between the discriminal processes of the same set of judgments is zero, Thurstone was able to scale "qualitative" attributes from observed proportions of the cases in which each member of a stimulus pair was chosen as having subjectively more


The authors describe an optical fiber control signal transmission system in which multiples frequency signals are used as an 8b control signal for a CPU control system consisting of Z80 data processors, motion control devices, and position sensors. Four control terminals are connected to the control center. Motion control devices are connected to the data processor installed in each control terminal. Frequencies at 100 kHz, 200 kHz, 300 kHz, and 400 kHz are used as series signals to specify the current operating states of the motion control devices, and the frequencies at 500 kHz, 600 kHz, 700 kHz, and 800 kHz are used as parallel signals to specify the four control terminals. The initial step in implementing the transmission system, including the function of the control bus and the configuration of the transmission system for the 8b parallel control signals, is discussed.<<ETX>>


MeV-GeV dark matter (DM) is theoretically well motivated but remarkably unexplored. This proposal presents the MeV-GeV DM discovery potential for a $\sim$1 m$^3$ segmented CsI(Tl) scintillator detector placed downstream of the Hall A beam-dump at Jefferson Lab, receiving up to 10$^{22}$ electrons-on-target (EOT) in 285 days. This experiment (Beam-Dump eXperiment or BDX) would be sensitive to elastic DM-electron and to inelastic DM scattering at the level of 10 counts per year, reaching the limit of the neutrino irreducible background. The distinct signature of a DM interaction will be an electromagnetic shower of few hundreds of MeV, together with a reduced activity in the surrounding active veto counters. A detailed description of the DM particle $\chi$ production in the dump and subsequent interaction in the detector has been performed by means of Monte Carlo simulations. Different approaches have been used to evaluate the expected backgrounds: the cosmogenic background has been extrapolated from the results obtained with a prototype detector running at INFN-LNS (Italy), while the beam-related background has been evaluated by GEANT4 Monte Carlo simulations. The proposed experiment will be sensitive to large regions of DM parameter space, exceeding the discovery potential of existing and planned experiments in the MeV-GeV DM mass range by up to two orders of magnitude.

. The albatross optimized flight maneuver – known as Dynamic Soaring (DS) – is nothing but a wonder of physics, biology, and engineering. In an ideal DS cycle, this fascinating bird can travel in the desired flight direction, for free, by harvesting energy from the wind, and hence, it achieves a neutral energy cycle. This phenomenon has triggered a momentous interest among aeronautical, control and robotic engineering communities; if DS is mimicked, we have arrived at a new class of Unmanned Aerial Vehicles (UAVs) which are very energy-efficient during part (or the full) duration of their flight. However, the DS problem is highly nonlinear, under-actuated, and dependent on the wind profiles. This has resulted in decades of DS control literature that, while making progress in addressing the control problem, seem not to be aligned well with the nature of the DS phenomenon itself. The control works associated with DS in the literature rely heavily on constrained optimal control algorithms, control designs that require a mathematical expression of the objective function, and predefined wind profile models. Clearly, a functioning controller for DS that allows meaningful bio-mimicry of the albatross, needs to be autonomous, real-time, stable, and capable of tolerating the absence of the expression of the objective function (similar to what the bird does). The qualifications of such controller are the very same characteristics of Extremum Seeking Control (ESC) systems. In this paper, we show that ESC systems existing in control literature for decades are a natural characterization of the DS problem. We provide the DS problem setup, design, stability, and simulation results of the introduced ESC systems. The results, supported by comparison with optimal control solvers, emphasize that the DS phenomenon is a natural expression of ESC systems in nature and that DS can be performed autonomously and in real-time with stability guarantees.


Objective To investigate the diagnosis and treatment of blunt pancreatic injury.Methods The clinical data of 16 patients with blunt pancreatic injury from 1983 to 2008 were analyzed retrospectively.Results 4 patients were treated nonoperatively.In 12 cases of operation patients,4 patients received operation of simple repair,drainage and distal pancreatectomy,6 patients administrated proximal pancreatic closure and distal pancreaticojejunostomy(Roux-en-Y),2 patients administrated Cogbill's technique and pancreatic-duodenum ectomy.14 patients were cured,2 patients died from traumatic shock,multipal organ injury and multiple organ failure.3 patients with fistula were cured by sufficient drainage.Conclusion Most of blunt pancreatic injury cases are without specific clinical manifestation,which causes lower confirming ratio and more misdiagnosis before operation.CT scan is the most useful imaging technique for detecting parenchymal lesions in a relatively early phase.ERCP is theoretically the ideal method.The most accurate one is explorative laparotomy.Different surgical procedure should be adopted according to the position and severity of pancreatic injury.

(111)-oriented metallic overlayers of Cu, Au, Pd, and Pt with thicknesses up to 3 atomic layers (AL) on Fe(110) or Co(0001) show evidence for d-like quantum-well (QW) states in spin-resolved photoemission spectroscopy. The noble-metal d-like QW states are not spin polarized and are well below the Fermi level. In contrast, the d-like QW states of Pd and Pt approach the Fermi level for about 3 AL, but are spin polarized only for the first AL. Thus both types of QW states do not mediate the antiferromagnetic interlayer exchange coupling in corresponding (111)-oriented magnetic multilayers.

Peace was a much sought-after value in the twentieth century, not only among Mennonites, but in the world at large. Among Mennonites, peace has been a core biblical value from Anabaptist beginnings in the sixteenth century. It remains part of the Mennonite landscape, part of the background scenery if not always in the foreground. Peace tends to become a foreground issue when there is some upset. The twentieth century was a century of much upset, and so peace sprung to the foreground through much of the century, but for different reasons as I shall note.

A theoretical and experimental investigation of the time delay characteristics of fiber Bragg grating-based Sagnac loops (FBGSLs) is presented. Analytic expressions for the phase and time delay of the FBGSL have been derived and excellent agreement is found between their predictions and experimental results for configurations incorporating uniform-period and chirped-period gratings. For symmetrical grating structures, it is found that the FBGSL time delay response is similar to that of the incorporated grating; with asymmetrical gratings, the FBGSL response is quite different. It is shown that wavelength-division-multiplexing filters exhibiting near-zero dispersion characteristics can be implemented using FBGSLs.


We have investigated the existence of any possible pair breaking mechanism in Cu 0.5 Tl 0.5 Ba 2 Ca 2 Cu 0.35 Zn 2.65 O 10− δ superconductor by carrying out post-annealing experiments in nitrogen, oxygen and air atmospheres. This material is grown in tetragonal structure with  a and c -axes lengths 3.879 A and 14.581 A; the c -axis length is found to decrease with the increased concentration of Zn in the final compound. The substitution of Zn at CuO 2 planar sites in formula unit Cu 0.5 Tl 0.5 Ba 2 Ca 2 Cu 3− y Zn y O 10− δ has given superconductivity for all the Zn doping concentration of y = 0.75, 1.5, 2.25, 2.5, 2.65. The zero resistivity critical temperature [ T c ( R = 0)], the quantity of diamagnetism and critical current [ I c ( H = 0)] are found to increase with increased Zn doping. In Zn doped samples, post-annealing in air has given a maximum increase in superconducting properties, which showed that final material is optimally doped with carriers in ZnO 2 planes. Since the superconducting properties are marginally suppressed in Zn doped samples by post annealing in O 2 and N 2 atmospheres, it has lead to a definite conclusion that pair breaking mechanism, suggested in previous studies, are absent altogether in our Cu 0.5 Tl 0.5 Ba 2 Ca 2 Cu 0.35 Zn 2.65 O 10− δ superconductor. The synthesis of Cu 0.5 Tl 0.5 Ba 2 Ca 2 Zn 3 O 10− δ superconductor by this method is extremely reproducible.


29 Interactions of indigenous peoples with the surrounding non-indigenous society are often the 30 main sources of social and environmental changes in indigenous lands. In the case of the 31 Suruí in Brazilian Amazonia's "arc of deforestation," these influences are leading to 32 deforestation and logging that threaten both the forest and the sustainability of the group's 33 productive systems. The Suruí tribal leadership has initiated a proposal for an economic 34 alternative based on Reducing Emissions from Deforestation and Degradation (REDD). This 35 has become a key case in global discussions on indigenous participation in REDD. The 36 realism of the baseline scenario that serves as a reference for determining the amount of 37 deforestation and emissions avoided by the proposed project is critical to assuring the reality 38 of the carbon benefits claimed. Here we examine the SIMSURUI model, its input parameters 39 and the implications of the Suruí Forest Carbon Project for indigenous participation in 40 climate mitigation efforts. 41 42

A scheme is proposed for the reconstruction of two-mode entangled states in cavity QED and ion traps. For a two-mode field we show that the Wigner function can be obtained by measuring the probability of a two-level atom being in ground states after resonant interaction with two classical fields and dispersive interaction with the two-mode cavity field displaced by resonant sources. For the two-dimensional motion of a trapped ion the Wigner function is obtained by measuring the probability of the ion in its ground electronic state after displacing the ion motion and then resonantly exciting the ion.

This article sets out to explore what it is to live in the postmodern age as an 'individual', that is,as someone with a distinct sense of self. Consideration is given both to the possibility that individualstoday, in the context of globalisation, may not have such a distinct sense of personal 'identity', andalso to what it is to have an identity. These questions are explored in relation to the so-calledpostmodern subject – or the subject in the age of globalisation, the age of hypercommunication,or of 'informatization' – which one may assume to be constituted very differently from the 'modern'subject of the 19th-century, or even more radically differently from premodern subjects. One couldsay that what Hardt and Negri regard as distinctive for postmodernity – informatisation, madepossible by advanced communications technology – is inseparable from the 'identity' of postmodernindividuals. Moreover, Derrida's insistence that the communications technology characteristic ofan era embodies a change in subjectivity (and hence, in identity), points to a significant clueregarding the identity of postmodern subjects. The aim of the present article is therefore to explorewhat all of these divergent considerations mean with regard to the issue of identity in thecontemporary world – whether one has reason to believe that identity has evaporated in the fluxof postmodern life, or if some of the theoretical perspectives invoked here enable one to affirmthe continued legitimacy of talking about identity today

The purpose of this thesis was to investigate the possibility of manufacturing filament for the Minifactory 3D printer in the Arcada plastics lab and if so how to do it and what materials could be used for filament. The main objective for the thesis was to achieve acceptable filament for the 3D printer. This Thesis is about the process of designing and manufacturing an extrusion die for the Arcada plastics lab. The thesis covers a broad range of manufacturing processes and design aspects during the different stages of manufacturing. The focus of the manufacturing processes lies on milling and drilling. Topics that the thesis tackles are design issues of extrusion dies and overcoming issues with compatibility with extruder mounts with limited tools. Manufacturing and designing of the extrusion die was done at Arcada. Arcada provided all the tools and raw materials required the part to be manufactured. Design software used in the thesis was Solidedge and Mastercam. The Solidedge software was used to achieve preliminary designs while Mastercam was used to finalize and generate toolpaths for the Haas Milling machine. The die was manufactured by CNC machining on the Haas milling machine located at Arcada plastics lab. Some other machines like a manually operated drill and a sawing arm were also used when machining the part. The die worked as designed and was able to produce filament with the correct dimensions for the 3D printer.


Information systems have become increasingly used by most organizations, their impact on society, the economy and the daily life of each of us is undeniably perceptible but on condition to manage them effectively to enjoy their benefits. To manage it effectively, requires that each company select a standard framework from multiple IT best practice managementthat are designed by experts, this choice is a problem for a long time in front the businesses. To solve this problem we will make a comparison between different frameworks ITIL, COBIT and CMMI, and we will propose a system facilitating the choice of the most suitable framework that responded to the need of a particular companies, the implementation and evaluation of the system has shown that it is very useful for them. Keywords—Information system, ITIL, COBIT, CMMI.


Standard Model has always come out with flying colours in all the experiments performed to date. Still, there are ample reasons to believe that it . is just an effective theory, valid upto a certain energy scale (which may be anything between the Planck scale and a few hundred GeV), beyond which signals of new physics should be observable. The following reasons may be cited for such a belief, the ordering is not according to importance, which is in some sense a subjective one.


writings of these great masters. These observations and doctrines are, to be sure, new fashioned a little, and modernised in the View of the Nervous Temperament; still, however, it is but an old song to a new tune.

This article studies the ability of security-level contracts to substitute for poor country-level investor protections. Using a cross-country sample of restrictive covenants, we find that bond contacts are more likely to include covenants when creditor protection laws are weak. Further, the use of restrictive covenants in weak creditor protection countries is associated with a lower cost of debt. We also find that strong country-level shareholder rights are not necessarily harmful to bondholders. Overall, the findings suggest that issuers and investors can create international contracts that overcome some of the deficiencies of country-level investor protections and facilitate access to external finance.

A precise ocean bottom map is often desired for ocean surveying. To meet the demand, the multi-beam echo sounder (MBES) has been developed and commonly used. An MBES usually forms multiple receiving beams across-track first, then determines the bottom echo time for each beam, and finally calculates depth from echo time and direction. In this paper, a sequential filtering approach, exploiting ping to ping data correlation, is proposed, which is capable of realizing fast and accurate estimation and tracking of the seafloor depth. By the employment of this method, when the measurement Signal-Noise-Ratio (SNR) is below 35dB, the root mean square error (RMSE) of depth estimation is much lower than the conventional approach, and nearly reaches the posterior Cramer-Rao lower bound. The results demonstrate that the sequential filtering approach, applied to MBES measurements, could be a promising technique for seafloor topography estimation and tracking.


The chemotherapy dose‐intensity in two adapted German BFM paediatric protocols (BFM 90 and NHL 86) was compared in contemporaneously treated adults <50 years with Burkitt lymphoma and B‐cell lymphoma unclassifiable, with features intermediate between diffuse large B‐cell lymphoma and Burkitt lymphoma (collectively referred to as BL). In BFM 90, primary prophylaxis with Granulocyte‐colony‐stimulating factor was used, postinduction treatment was started at granulocytes ≥0.5 × 109/L (≥1.0 × 109/L in NHL 86) with a higher mean methotrexate dose (2.9 g/m2/cycle, n = 23; 1.6 g/m2/cycle in NHL 86, n = 22, P < 0.001). Intervals between consecutive treatment‐cycles were shorter in BFM 90 (P < 0.001) with no additional toxicity. However, the two‐year failure‐free survival with BFM 90 (82%) was similar to that achieved with NHL 86 (72%, P = 0.33). We conclude that BFM 90 enables safe intensification of therapy in young adults with BL compared to NHL 86, but registry‐based studies are required to further evaluate the antineoplastic effects and cost‐effectiveness of the two therapeutic approaches.

After the reform, the planned economy was replaced with the market economy in China and a lot of various non-governmental organizations (NGOs) including the association(社團), the private non-enterprise units and the foundations were constructed. Therefore, the Chinese Communist Party (CCP) and government has formed the administration system for the NGOs through the institutionalization and legislation. In the early reform years, the NGOs' administration system maintained the pre-reform socialist ways. However, after 1988, there have been the gradual institutionalization and legislation of the NGOs' administration system together with the formation of the NGOs' unific registration management system under control of the State Council and the Ministry of Civil Affairs. It might be seen as the retreat of the party and the strengthening of the State Council and the Ministry of Civil Affairs. But it was just the reassignment of the responsibility between the CCP and the State Council and not the change of the party being in charge of the society. The State Council and the Ministry of Civil Affairs are in charge of the administrative management of the NGO, but the principle and policy for the NGO administration is been determined by the CCP and the leadership of the CCP has unchanged. The CCP recognize the inevitableness of the NGO's growth and realize it as the bridge between the party and the mass. But at the same time the CCP suspect them as the soil of the anti-China and anti-communist party which may conspire with the hostile force of the external (west) to threaten the legitimacy of the CCP. So, the CCP and the Chinese government take strict control and restriction on the NGOs by ways of formatting the administrative control system on the one hand, and constructing party branches in the NGOs on the other hand. But according to the 2009 official statistics, the CCP branches have been constructed just a half in the local NGOs. More severe, the party and state have no means to manage the presumably more than 3million grass root NGOs. This shows the adaptation and limit of the party-state to the changing Chinese society.

This article aims to analyse the Twitter posts which contain the hashtag #casamentoreal, referring to the wedding between the American actress Meghan Markle and the British prince Harry, member of the most popular royal family in the world. The main goal is to understand, through the corpus, cultural aspects and power relations, which are revealed in the Twitter comments, proposing a qualitative interpretation of the data, by the Cultural Studies perspective. Therefore, we have opted to apply a quanti-qualitative method of analysis of semantic nets based on the collection of digital contents, which allow the investigation of terms most frequently related to the discourses that compose the corpus. As a result, we identify as central axes of the analysed content: race and ethnicity; gender, globalization and cultural hybridism, revealing perspectives that reinforce the hegemonic pattern, as well as a critic discourse that questions power structures socially consolidated. Keywords: Royal wedding. Social networks. Semantic analysis. Culture.


Abstract The aim of this study was to analyze the morphological parameters (viscosity, viscous elasticity and the rate of volatile component loss) of salicylic and boric acid-containing magisterial formulae (ointments). Moreover, the effects of these parameters on the diffusion rate of a therapeutic agent (salicylic acid) to an in vitro external compartment were analyzed. Finally, the applicatory properties of the ointments prepared by way of a conventional technique (in a mortar) and with the aid of an unguator, were compared. The rheological parameters of the analyzed ointments suggest that the preparations made with an aid of an unguator, irrespective of the physicochemical characteristics of their vehicles, are characterized by higher values of diffusion coefficient (D). In addition, conventionally-prepared formulae containing salicylic were shown to be characterized by better viscous elasticity. Surprisingly, irrespective of the preparation technique, the ointments based on an absorptive vehicle (containing lanolin) were characterized by similar viscous elasticity. The rate of volatile (water) component loss from ointments containing a 3% solution of boric acid suggests that such formulae lose no more than 2.3% of their mass when exposed at 37℃. Therefore, the viscosity of such ointments applied onto a patient's skin should remain relatively stable.


Fresh leaves of different maturities from lower, middle and upper parts of the stalks of Yunyan 85, a variety of fluecured tobacco were determined superoxide dismutase (SOD), peroxidase (POD), catalase (CAT) activities, relative permeability of cell membrane (RP) and malonaldehyde (MDA) content. Then, those leaves were subjected to fluecuring trial and chemical composition analysis. The optimal appearance of lower and middle leaves for priming was greenish or light yellow in color, with the main veins completely white, 1/2 to 2/3 lateral veins turning white, a lot of tomenta falling off, and the rims and tips of leaves beginning to wither. Meanwhile, the optimal appearance of upper leaves for priming was yellow in color, with the main veins completely white, 2/3 to all of the lateral veins turning white, most of tomenta falling off, and the rims and tips of leaves having withered. when the leaves at different parts of the stalks were primed according to the normal appearance of maturity mentioned above, their SOD, POD and CAT activities decreased rapidly. This resulted in the accumulation of the active oxygen, which in turn increased the lipid peroxidation of the plasma membrane and promoted the accumulation of MDA, and caused the increase of the RP of the plasma membrane. Which was favorable for leaves curing and quality improvement, such as the increasing of superior leaves and proper ratios of chemical compositions.


This paper reveals a novel handheld device to measure the peak nasal expiratory flow rate of the two nasal cavities individually and simultaneously. Significantly, when using this device, the patient needs to inhale from the mouth and exhale from the nose, as a usual breath, and importantly there is no need to take extra effort to exhale. The key detection mechanism used is the anemometer technique and the measurement is done by using an optical wheel encoder and an ATmega328p microcontroller. The device is capable of measuring the exhaled airflow rate with an accuracy of ± 1 LPM. It also allows measuring the number of breaths per minute together with the respective temperature and the relative humidity of the exhaled airflow of the two nasal cavities separately. Two DHT22 sensor modules are used to measure relative humidity and temperature with an accuracy of ±1 %RH and ±0.5℃ respectively. This can be used by a Rhinologist as an initial diagnosing tool for several diseases, as the device allows them to get an idea about the patient's exhaling behavior of the nasal airflow instantly. The device would be beneficial in the sports sector as a physical fitness indicator by means of the breathing style.

This study was conducted to investigate on food component characteristics of seafood cooking drips (skipjack tuna cooking drip, octopus cooking drip and oyster cooking drip) as a source of functional seasoning. Heavy metal contents of seafood cooking drips were below food safety level. Among seafood cooking drips concentrated to 5 folds, the crude protein content was the highest (18.1%) in skipjack tuna cooking drip (SCD). The free amino acid content and taste value were higher in SCD than in other seafood cooking drips, and the major free amino acids were glutamic acid and aspartic acid. Total amino acid content of SCD was 16.2 g/100 mL and the major amino acids were glutamic acid (11.9%), proline (9.2%), glycine (9.1%) and histidine (11.5%). SCD in comparison with other seafood cooking drips showed the highest angiotensin I converting enzyme (ACE) inhibitory activity at IC?? of 14.1 ㎎/mL. These results suggested that SCD could be used as a source of functional seasoning.

This study shows the forms of questions making by 3 and 5 years old children. Purposive sampling was used to determine the objects of the study.. The forms were found through descriptive qualitative approach by implementing three methods, observation, interview, and note taking techniques to collect the data. To analyze the data, the researchers used data reduction, categorization, and conclusion. The researchers confirmed that there were four kinds of questions-making processes employed by Preschoolers. They were sign form, single word form, double word form or phrase, and clause or sentence.  It can be concluded that the differences between those two ages were in term of the frequency of using the forms. The 3 years old child used single and double word forms frequently, while the 5 years old child used double word form or phrase and clause frequently.


This lecture first presents an outline of research work by which many troublesome problems in the design and construction of large tankers were solved, and secondly introduces the largest tanker ever built in Japan, the Nissho Maru, of 130 000 deadweight tonnage.With regard to design of such tankers, two points, that is,(1)reduction in length of ship (L), and(2)increase in depth (D),should be taken into account from the standpoint of weight saving and of easy fabrication.Researches into structural problems of tank parts and into the dynamic pressure of cargo oil tank, due to ship motions, are described briefly, and show that the maximum impulsive pressure in model tests may be up to 5 times the static fluid pressure and may be observed at the tank top when the natural period of fluid in the tank is resonant with the oscillation period of the ship.Special care should be taken in the detailed design of longitudinals, struts and so on, otherwise cracks will initiate easily at the point of stress concentratio...


Modern museums were born because of the spatial composition program, exhibition techniques, and the diversification of architectural styles. Frank Gehry is an architect pursuing extreme forms and thinks modern box-shaped architecture is bland and lacks feeling/passion/love. This paper aims to examine the characteristics and meaning of the museums designed by Gehry, Gehry's unique architectural view, and the elements of his museum designs. As a methodology, the classification of modern museums in Newhouse's "Towards a New Museum "and trends in modern museum architecture are classified into six categories in Montaner's book "Museums for the 21st Century," which are used as a framework for comparative analysis to point out the characteristics of the Gary Museum and derive the location and meaning in modern museum architecture. The result shows that his architectural tendencies of fragmentation and duality are applied to the Gary Museum, revealing complex characteristics in terms of composition by contrasting combinations of formality and irregularity in materials and forms. The intricate design of the Gary Museum reveals its strong presence by creating a sculptural museum that encourages a four-dimensional experience both inside and outside. It was statistically proven that the above characteristics of the Gary Museum represent an aspect of the modern museum that is becoming a popular entertainment medium. A relaxed and comfortable exhibition environment was promoted by weakening the excessive rigidity in the exhibition space through the changeable ceiling treatment. Gary's museums were born between radical experimentalism and a pragmatic professional temperament.


The dominant paradigm in statistical inference relies on a structure of i.i.d. data from a hypothetical infinite population. Despite its success, this framework is inflexible under complex data structures, even in those cases where it is clear what the infinite population represents. In this paper, we explore an alternative framework whereby the basis of inference is only an invariance assumption on the model errors, such as exchangeability or sign symmetry. As a general method to address this problem of invariant inference, we propose a randomization-based procedure. We prove general conditions for asymptotic validity of this procedure, and illustrate in many data structures, including clustered errors in one-way and two-way layouts. We find that invariant inference via residual randomization has three appealing properties: (1) It is valid under weak and interpretable conditions, allowing for problems with heavy-tailed data, finite clustering, and even some high-dimensional settings. (2) It is robust in finite samples as it does not rely on the regularity conditions needed for classical asymptotics. (3) It addresses the problem of inference in a unified way that adapts to the data structure. Classical procedures like OLS or bootstrap, on the other hand, presuppose the i.i.d. structure, and need to be modified whenever the actual problem structure is different. This mismatch in the classical framework has led to a multitude of robust error techniques and bootstrap variants, which frequently confounds applied research. We corroborate these findings with extensive empirical evaluations. Residual randomization performs favorably against many alternatives, including robust error methods, bootstrap variants, and hierarchical models.


An effect is described in which colour matches established under spatially uniform conditions are disturbed by the introduction of spatial modulation in one half of the adaptation field, even though the mean illumination level and spectral composition of the spatially non-uniform adaptation field was the same as that of the uniform adaptation field. The effect was studied for a range of monochromatic test and adaptation wavelengths, and its variation with adapting intensity and frequency of spatial modulation is examined. The origin of the effect is discussed.


PurposeThis study investigates business model innovation in small- and medium-sized manufacturing enterprises (SMEs) and its impact on firm growth.Design/methodology/approachThe study was based on analyzing data collected through a questionnaire survey. Structural equation modeling was applied to test the hypotheses.FindingsBusiness model innovation has a positive effect on SME growth in the manufacturing sectors. Moreover, growth is also achieved through the indirect effect of business model innovation on customer trust and commitment.Practical implicationsManagers will benefit from understanding how business model innovation can help their companies to overcome resource constraints and achieve sustained growth. When manufacturing SMEs engage in modular or structural changes to their business model, they may find it worthwhile to focus on maintaining a relationship of trust and commitment with their customers.Originality/valueThis study highlights business model innovation as a unique and important, yet underexplored, factor in manufacturing SME growth. The findings also untangle the complex processes of customer relationship management by which business model innovation improves manufacturing competitive advantage for SMEs.


Welding steel armor reduces the armor materials protection capability. Several industrial and military welding standards exist for welding armor materials with the primary focus on joint strength rather than ballistic integrity.The Heat Affected Zone (HAZ) created by the welding process introduces vulnerabilities in the protection system. The process and designs that we have demonstrated include mitigation features that eliminate the ballistic degradation and provide uniform protection across all armor materials.In this study we used finite element simulation of the welding process to perform trade studies evaluating welded joint designs, and to show how the designs could be altered to both optimize armor performance and reduce welding heat input. A beneficial effect of reduced heat input was the corresponding reduction in welding-induced residual stresses, an overall reduction in assembly distortion in the assembly, and improvement of the armor performance.The simulated welding process included the creation of the heat affected zone and the development of residual stresses in the structure. ABAQUS finite element software was used for the simulation with the aid of an extensive material property database created over the wide range of welding temperatures.The finite element simulation predictions were validated and verified with excellent results by metallography and micro-hardness measurements. Live-fire ballistic tests were used as the final proof of measurable design improvements. Finite element welding simulation was shown to be an effective tool for improving upon standard welded armor designs, and above all in improving human safety.


Falling accidents, including slipping, tripping and falling, are the primary reason of injury related to death not only for elderly, but for young people or worker happening at workplace also. If falling accident can be early detected in pre-fall or critical fall phase, called pre-impact fall detection, it will be very useful such as conducting airbag inflation. Furthermore, various detection methods, with an uncomplicated threshold detection method, do maximizing the true positive prediction values but the lead-time, time before subject impacts to the floor, will likely increases the chance of false alarms. Consequently the researcher found that the using of adaptive threshold may reduce false alarms. In this paper, the dynamic threshold method, automatically adjustable threshold for pre-impact fall detection in wearable device, has been proposed and experimented. For our evaluation, 192 instances of several kinds of activity of daily living and falling, were captured. All activities were performed by 6 different young healthy volunteers, 4 males and 2 females, aged between 19 and 21. The several experiments were conducted for performance evaluation including sensitivity, specificity and accuracy measurements. The results of proposed method can detect the pre-impact fall from normal activities of daily living with 99.48% sensitivity, 95.31% specificity and 97.40% accuracy with 365.12 msec of lead time. The results confirm that our proposed method with automatically adjustable threshold based on motion history, is suitable for using in pre-impact fall detection system than fixed threshold based method.


Shale gas exploration in China is still in its infancy. It is proven that shale gas occurs in most of Chinese basins by geologically comparing the hydrocarbon generation with those in the eastern U. S. These basins would be the key target for shale gas exploration. The mid-eastern region, the southern region, the northwestern region, and the Qinghai-Tibet region present broad prospect for shale gas exploration. The southern region in particular has stable thick hydrocarbon-rich shale formations. Shale gas, with a typical"self-generation and self-accumulation" feature, is resistant to damage, despite of the strong late tectonism. Direct evidence of shale gas development in Sichuan Basin has been found, e.g., Weiyuan. Shale gas exploration should start in the area of high organic matter abundance and high degree of thermal evolution, preferably accompanied by the development of natural cracks.


Tapping-mode atomic force microscopy is used to image the conducting network of polyaniline inside organic blends. The greater stiffness of the conducting polymer phase with respect to the matrix leads to good resolution phase contrast imaging. Cross-section images provide a unique insight in the distribution of the conductive phase within the matrix.


The Fermi statistical model of particle production [1,2, 3, 4] has been used extensivelyin the field ofrelativisticheavyion collisions [5]. Particleabundanciesand spectraboth at Super Proton Synchrotron (SPS) [6, 7, 8, 9, 10,11, 12] and Relativistic Heavy Ion Collider (RHIC) [13,14, 15, 16, 17, 18] energieshavebeen analyzedin this way.The quality of fits to experimental results was such thatit became possible to discuss hadronization conditionsquantitatively, but the conclusions of the groups differ.For example the values of temperature range from as lowas 110 MeV [9, 14, 15, 16] to 140 MeV [10, 13] to as highas 160, 170, and 180 MeV [6, 8, 11, 15, 17, 18] at bothSPS and RHIC energies.These differences are on a closer inspection not verysurprising, since the (tacit) assumptions made abouthadronization mechanisms differ. However, this meansthat before we can say that the freeze-out temperaturehas been determined, we must understand precisely theorigins of these differences, and proceed to ascertainwhich model is applicable. We shall suggest experimentalobservables which will be particularly sensitive to the dif-ferences between the hadronization scenarios, in the hopethat further experimental study will allow to understandthe statistical hadronization mechanism.We begin with an overview of the differences betweenhadronization scenarios and their relation to the physi-cal assumptions used. Every model discussed here hasbeen extensively studied before, and has gained accep-tance of some part of the heavy ion community. Thetheoretical principles that we invoke are well understood,and the methods we use can be found scattered in liter-ature. We shall concentrate here on an analysis of reso-nancesproducedin aheavyioncollision. Direct detectionof hadronic short-lived resonances has become possiblethrough invariant mass reconstruction [19, 20, 21, 22].Resonances have already been proposed as candidatesfor differentiating between freeze-out models [23]. Res-onances are a sensitive probe of the freeze-out tempera-ture, since the ratio of yields of particles with the samequark composition is insensitive to both fugacities andphase space occupancies, and mass differences are greaterthan the hadronization temperature considered.Here we shall develop this reasoning one step further:If particles were to be emitted from a static thermalsource, and feed down corrections were performed, theratio of resonance to daughter particle would be indepen-dent of m


Phosphorene possesses a unique combination of physical and chemical properties, including tunable direct bandgap, anisotropic electronic and optical properties. However, application of phosphorene is hampered by its fast degradation under ambient conditions. It is believed that H2O and O2 play key roles in the instability of phosphorene, but their exact contributions have not yet been completely understood in experiment. Herein, a technique of probing the mechanism of phosphorene oxidation through the evolvement of its photoluminescence spectra in a liquid suspension is introduced. With the addition of H2O2, the photoluminescence intensity of the suspension surprisingly increases, indicating a passivation effect due to the formation of phosphorene oxide, which is also verified by Raman spectroscopy. In contrast, direct addition of H2O leads to irreversible and rapid degradation as shown by the quenching of photoluminescence. Furthermore, monolayer phosphorene suspension photoluminescence at 2.17 eV is obtained by completely eliminating effects from contaminations, substrate strain, dielectric substrate, and oxidation of samples. Solvent protection in combination with the optical probing method provides an effective approach in investigating the chemistry of active materials like phosphorene. Phosphorene has great potential in the range of sensing applications including high‐resolution H2O2 and humidity sensors.


Adult studies show a link between sleep deprivation & increased CV factors, plus higher obesity & diabetes risk. Does the same hold true for teens?


The nature of axion cosmology is usually said to depend on whether the Peccei–Quinn (PQ) symmetry breaks before or after inflation. The PQ symmetry itself is believed to be an accident, so there is not necessarily a symmetry during inflation at all. We explore these issues in some simple models, which provide examples of symmetry breaking before and after inflation, or in which there is no symmetry during inflation and no phase transition at all. One effect of these observations is to relax the constraints from isocurvature fluctuations due to the axion during inflation. We also observe new possibilities for evading the constraints due to cosmic strings and domain walls, but they seem less generic.


We present full three-dimensional numerical calculations of single vortex states in rotating dipolar condensates. We consider a Bose-Einstein condensate of $^{52}\text{C}\text{r}$ atoms with dipole-dipole and $s$-wave contact interactions confined in an axially symmetric harmonic trap. We obtain the vortex states by numerically solving the Gross-Pitaevskii equation in the rotating frame with no further approximations. We investigate the properties of a single vortex and calculate the critical angular velocity for different values of the $s$-wave scattering length. We show that, whereas the standard variational approach breaks down in the limit of pure dipolar interactions, exact solutions of the Gross-Pitaevskii equation can be obtained for values of the $s$-wave scattering length down to zero. The energy barrier for the nucleation of a vortex is calculated as a function of the vortex displacement from the rotation axis for different values of the angular velocity of the rotating trap.


DNA cleavage by a series of nonheme iron complexes supported by pentadentate carboxamido ligands, dpaqR (R = OMe, H, Cl, and NO2), was evaluated in the presence of a reducing agent under air and in the presence of hydrogen peroxide. Cleavage efficiency clearly increased as redox potential became more positive. These results provide an opportunity for the designing of Bleomycin mimics with higher activity.


THE TITLE of this paper may sound somehow paradoxical. The world and the war which Thucydides describes are commanded by force and by violence. The Athenian empire is founded on fear and gathers only hatred. The hardness of war develops, among the people, ambition and greed, which flourish in civil strife: 6 7rbXEJos . . . lLatos ML doKaXos. It would seem, therefore, that fairness and kindness have no place there. Yet, I have shown elsewhere' that there are, in Tlhucydides' work, some hints showing a regret that Athens' power should not rest on good-will, or eunoia. And what should she have done in order to inspire such goodwill? The first answer that comes to mind is that she should have acted according to justice; and this is indeed suggested.2 Justice is what can be opposed to force and violence. In Athens' case it meant respecting the cities' autonomy. And this is just what they wanted. But justice is not always easy to define, in time of war or civil strife, nor is it always easy to follow, when passion and power invite to very different actions. It may therefore require the help of some general disposition or virtue which would support moderation-such as the mild and tranquil virtues, which are usually appreciated between friends, or within a family, and which are the ornaments of peace. Among them are 'R76brqls, rLELKELa, and rpa67r7s. And it is a fact that, when we look a little more closely at Thucydides' work, a regret of these virtues can be as clearly detected as the regret of eunoia. Where and how it shows may be worth considering, and it occurred to me that such a theme, where gentleness and firm lucidity were for once reconciled, was particularly apt to be dedicated to the scholar whom we honour on this occasion. First of all, it is remarkable enough to see that even the old Homeric adjective ipios is not unknown to Thucydides. Epios, in Greek, is generally used to describe the kind manners a father displays towards his children; more than his behaviour, it qualifies his tone and general gentleness. Neither Isocrates nor Polybius uses the word any more. But Thucydides uses it, in three different passages. Or, to be quite accurate, he uses it in the comparative; and the fact is not devoid of meaning: for, in that harsh world, there is no place for real gentleness; but one may long, at least, for


Abstract In this article, a fixed-frequency phase-shift-controlled full-bridge series-parallel (or LCC-type) resonant converter that uses a capacitive output filter is proposed. Steady-state analysis of this converter is performed by using a complex AC circuit analysis approach. Based on the analysis, a simple design procedure is given and exemplified with a design example of a 200- to 220-V DC input, 300-W, 100-V output converter. The relationship between the design parameters, switch stresses, and converter size is illustrated. Both computer simulation and experimental results on a lab prototype converter are presented to verify the performance of the designed converter for varying input voltage and load conditions. It is shown that this converter requires a narrow variation in pulse width for a wide variation in the load, while the peak current through the switches decreases with the load current. One typical application of this converter is for use as a second stage for AC-to-DC converters.

Publish/subscribe (pub/sub) is a popular communication paradigm in the design of large-scale distributed systems. A fundamental challenge in deploying pub/sub systems on a data center or a cloud infrastructure is efficient and cost-effective resource allocation that would allow delivery of notifications to all subscribers. In this paper, we provide answers to the following three fundamental questions: Given a pub/sub workload, (1) what is the minimum amount of resources needed to satisfy all the subscribers, (2) what is a cost-effective way to allocate resources for the given workload, and (3) what is the cost of hosting it on a public Infrastructure-as-a-Service (IaaS) provider like Amazon EC2. To answer these questions, we formulate a problem coined Minimum Cost Subscriber Satisfaction (MCSS). We prove MCSS to be NP-hard and provide an efficient heuristic solution based on a combination of optimizations. We evaluate the solution experimentally using real traces from Spotify and Twitter along with a pricing model from Amazon. We show the impact of each optimization using a naive solution as the baseline. Using a variety of practical scenarios for each dataset, we also show that our solution scales well for millions of subscribers and runs fast.


A study on the use of Salvia hispanica as green corrosion inhibitor for 1018 carbon steel in 0.5 M H2SO4 has been carried by using gravimetric and electrochemical techniques. Techniques include weight loss, potentiodynamic polarization curves, electro-chemical impedance and noise measurements. All different techniques showed that Salvia hispanica acts as good inhibitor, with its efficiency increasing with the concentration. This is due to the physical adsorption of Salvia hispanica following a Langmuir type of adsorption forming a passive film. Additionally, electrochemical noise results indicated a reduction in the pitting corrosion susceptibility when Salvia hispanica was added to the solution.


A series of CuII and ZnII complexes with new ligands having either one or two substituted phenolates appended to the 1,4,7-triazacyclononane frame were prepared and characterized by optical absorption, EPR, NMR, and/or resonance Raman spectroscopy, cyclic voltammetry, and, in eight cases, X-ray crystallography. Features of the active site geometries of the CuII−tyrosinate forms of galactose and glyoxal oxidases (GAO and GLO) were modeled by these complexes, including the binding of a redox-active phenolate and an exogenous ligand (Cl-, CH3CO2-, or CH3CN) in a cis-equatorial position of a square pyramidal metal ion. The role of the unique ortho S−C covalent bond between a cysteine (C228) and the equatorial tyrosinate (Y272) in the proteins was probed through an examination of the optical absorption and electrochemical properties of sets of similar complexes comprised of phenolate ligands with differing ortho substituents, including thioether groups. The o-alkylthio unit influences the PhO- → CuII LMCT tran...


The multidimensional statistical analysis of outcomes of the full-time first year students of Physics &Technics Institute of Tomsk Polytechnic University who studied Higher mathematics course is carried out. We review a system of 4 indicators: EC outcomes of introductory mathematical test, CERT1 outcomes of currently studied «Mathematics 1.1» test realized in the middle of a semester, CERT 2 outcomes of currently studied «Mathematics 1.1» test realized at the end of the semester, EX outcome of classical exam made. Correlation analysis revealed a highly significant positive correlation linkage between CERT and EX marks. Furthermore we applied a factor analysis for our initial data. It shows that there are two indicators F1 the resulting advancement factor on «Mathematics 1.1» {as a sum of CERT 1+CERT 2+EX} and F2 the factor of entering control. In such a way constructed 2D factor space {F1, F2} the method of K-averages makes us possess to find a high-quality 4-clusters model who unite 10 student groups in four clusters. Within the limits of analysis of variance the homogeneous groups of clusters are selected for each factor. These results of clustering outcomes of an estimation of knowledge levels can be considered in the course of higher education training for the estimation of quality of student knowledge taught.


Abstract The twin effect of thermal conductivity and electroconductivity on the flow of fluid in an inclined porous channel was carried out. A combination of Laplace transform and undetermined coefficients method were used to determine the solution of the governing equations of motion and energy. Analysis of the solution using graphs showed that decrease in temperature was observed as a result of increase in radiation, prandtl number, thermal conductivity and free stream frequency while an increase in temperature brings about a corresponding increase in heat generation term. For decrease in velocity profile of the fluid, increase in magnetic field, angle of inclination and electroconductivity are the causes while increase in buoyancy force, Reynolds' number, porosity and stream frequency, increases the velocity profile of the fluid.


Synthesis of the fluorinated diblock copolymer nanoparticles of poly(dodecafluoroheptyl methacrylate)-b-poly(methyl methacrylate) (PDFMA-b-PMMA) by RAFT dispersion polymerization is performed in supercritical carbon dioxide. Fluorinated macro-RAFT agents were first prepared via RAFT solution polymerization and characterized by NMR and GPC. The RAFT-terminated poly(dodecafluoroheptyl methacrylate) (PDFMA) homopolymers actually act as in situ stabilizer for the subsequent synthesis of the PDFMA-b-PMMA block copolymer nanoparticles by RAFT dispersion polymerization while exhibiting good control on the well defined spherical particles formation. SEM images show that the average size of these synthesized diblock copolymer nanoparticles was 425 nm with a narrow size distribution (1.13), which are close to the literature data for conventional MMA dispersion polymerization with a fluorinated CO2-philic stabilizer in ScCO2.


In recent years, noble gas plasmas in magnetic fields have been investigated. Experimental results for the Hall coefficient have been made available. We compare these with results calculated using linear response theory in the Zubarev formalism. In this work, we investigate the possibility of using Hall voltage measurements to determine the electron concentration of partially ionized plasmas. (© 2007 WILEY‐VCH Verlag GmbH & Co.

In the process of monitoring the performance of nuclear power plant systems with the objective of fault identification and diagnosis, uncertainty is introduced. This uncertainty must be accounted for in rule-based systems, which are used for this purpose. In this context, uncertainty consists of two parts: randomness, meaning the uncertainty of occurrence of an object, and fuzziness, expressing the imprecision of the meaning of the object. For instance, for an engineering device, let us consider the proposition: E will increase {approximately}20% with a probability of 90%. The variable E could be any performance parameter of interest. The uncertainty in this statement has two components: one related to randomness, which is expressed by a probability of 90%, and another component due to fuzziness, which is expressed by {approximately}20%. From fuzzy set theory, the meaning of {approximately}20% can be precisely defined by a possibility distribution {sub {pi}X}, which may be induced by physical constraints, or it may be epistemic in nature, in which case it is induced by a collection of propositions. From probability theory, the construction of a probability density function based on frequency distributions from experimental and sensor data and observations can precisely define the meaning of the words amore » probability of 90%. Discussed is a methodology for inferencing and decision making under uncertainty for use in rule-based systems, where the knowledge about the modeled system is both probabilistic and possibilistic, and apply it to the monitoring and diagnosis of the performance of a nuclear reactor's residual heat removal (RHR) system.« less

Support for Internet host mobility is increasingly important with the proliferation of wireless and mobile commu- nication devices. Stream Control Transmission Protocol (SCTP) is a plausible choice in the Internet with its unique features like multi-homing and Dynamic Address Reconfiguration extension. We have proposed Cellular SCTP (cSCTP), which is an SCTP- based transport layer mobility solution that aims better handoff performance. In this paper, our focus is the handoff management functionality of cSCTP. We propose an approach to implementing duplicated data transfers during the handoffs to improve the performance. We also present preliminary simulation results using the QualNet network simulator. I. INTRODUCTION The need for "host mobility support" in the Internet is increasing with the proliferation of wireless and mobile com- munication devices. Network layer solutions (such as Mobile IP) are common to support host mobility in the Internet. Network layer solutions however have their own drawbacks, such as the need of support from the network (Home/Foreign Agents), triangular routing, long handoff latency, etc. More- over, network layer solutions hide the mobility from the transport protocols, where the flow and congestion control
