We consider a two polynomials analogue of the polynomial interpolation problem. Namely, we consider the Mixing Modular Operations (MMO) problem of recovering two polynomials f ∈ Zp[x] and g ∈ Zq[x] of known degree, where p and q are two (un)known positive integers, from the values of f(t) mod p+g(t) mod q at polynomially many points t ∈ Z. We show that if p and q are known, the MMO problem can be reduced to computing a close vector in a lattice with respect to the infinity norm. Using the Gaussian heuristic we also implemented in the SAGE system a polynomial-time algorithm. If p and q are kept secret, we do not know how to solve this problem. This problem is motivated by several potential cryptographic applications.


A study is made of the kinematical properties in four-momenta <1 space of scattering amplitudes involving two incoming and two outgoing massive particles with arbitrary spins. For reasons of simplicity in considering analytic properties, the M function, or Spinor Amplitude, formalism is employed, a choice that has no practical effect on the results. Complex covl}riance at points where the scattering functions are holomorphic is employed to find points where there are kinematical restrictions on them. The effect of discrete symmetries is then .~', accounted for. It is sho'wn that a decomposition into sums involving invariant amplitudes free of any kinematic~l singularities or zeroes and k:lnematical factors, or "standard covariants," is possible, provided the latter have certain precisely specified properties derived from the kinematical behavior of the Spinor Amplitudes. Our approach is contrasted to that using center-of-mass helicity amplitudes. Actual discussion of the methods by 'which standard covariants may be constructed is left for a. second paper.


By the early 1990s Willow Creek Community Church near Chicago, Illinois, was perhaps the most prominent church in the United States. It was the hot ecclesiastical news of the day. Articles about the church appeared in publications across a range of readerships: Woman's Day, US Catholic, the New York Times, Fortune, the Wall Street Journal, Time magazine, and Christianity Today. Sociologists of religion, too, were writing their dissertations on this rapidly growing church. Even the bulwark of serious scholarship on liturgical matters, the North American Academy of Liturgy, took a field trip to one of this congregation's services in the 1990s when the Academy had its annual meeting in Chicago. In addition, increasing numbers of church leadership teams took their own pilgrimages to Illinois to see, appropriate, and imitate in hope of replicating Willow Creek's success. What was it about Willow Creek that garnered the attention? It was the church's seeker services on Saturday and Sunday. In order to provide an accessible, enjoyable experience for its suburban target audience, which the church called "Unchurched Harry and Mary," Willow Creek had turned the church world upside down as it sought to remove every boring barrier that might have led these suburbanites to avoid other churches. The result was a thorough revisioning of Sunday morning. Relevant messages? Professional-grade popular music? Quality dramas? Outstanding hospitality (which reached even to thinking through the dynamics of parking)? Relaxed atmosphere? Attractive, business-style campus? Willow Creek had thought through all of these issues as it planned and led its multiple seeker services every weekend. This seeker-driven approach taught by Willow Creek offered a model for revolutionizing thousands of congregations. What was not nearly as prominent, capturing neither the headlines of the press nor the attention of the eager-to-imitate pilgrims who sojourned to Illinois, was that Willow Creek was undergoing its own liturgical migration. But this move was not happening on the weekends. It was in the congregation's midweek worship services. These midweek services were the ones planned and held for the active Christian believers in the congregation. (At the time, Willow Creek carefully avoided calling its weekend services for seekers "worship." They were for evangelism and outreach, not the worship of God. Its worship services—the "New Community" services—occurred mid-week.) Initially these midweek services were a bit of an afterthought since the driving vision for the congregation's start in the late 1970s was evangelistic outreach. These mid-week services were along the line of a Bible Study with a few contemporary songs topically selected and placed in a nice order. But that status changed after the summer of 1982 when the congregation's lead pastor, Bill Hybels, returned from a summer break having attended a small, charismatic Black church in


A theory of the formation and growth of the photographic latent image and of the development process in the crystal containing it is outlined. It is assumed that the latent image consists of a small region of the (silver halide) crystal in which the atomic arrangement is the ``tetrahedral'' B3 type (or another closely related arrangement), stabilized by the presence of one or more photoelectrons, with or without extra silver ions.


Whose values should count – those of patients or the general public – when adopting the quality-adjusted life year (QALY) framework for healthcare decision making is a long-standing debate. Specific disciplines, such as economics, are not wedded to a particular side of the debate, and arguments for and against the use of patient values have been discussed at length in the literature. In 2012, Sinclair proposed an approach, grounded within patient preference theory, which sought to avoid a perceived unfair discrimination against people with disabilities when using values from the general public. Key assumptions about general public values that beget this line of thinking were that 'disabled states always tally with lower quality of life', and the use of standardised instruments means that 'you are forced into a fixed view of disability as a lower value state' (Sinclair, 2012). Drawing on recent contributions to the health economics literature, we contend that such assumptions are not inherent to the incorporation of general public values for the estimation of QALYs. In practice, whether health states of people with disabilities are of 'lower value' is, to some extent, a reflection of the health state descriptions that members of the public are asked to value.

This article presents a hybrid microgrid configuration with a flying capacitor dual-output (FCDO) converter. The output ports of the FCDO converter can directly interface ac sources/loads operating at different amplitudes and frequencies without additional ac/dc/ac converter units. Compared to the conventional configuration, the hybrid microgrid with the FCDO converter operates at multilevel voltages, reduced power conversion stages, less power switch count, and fewer control loops. The article also presents a cascaded model predictive control (CMPC) algorithm for such configuration to control the variables, namely three-phase dual-output currents, ac/dc bus and FC voltages, and active/reactive power. The proposed CMPC sequentially executes multiple single-objective MPC units with adaptive dynamic reference (ADR) models to control the multivariable. The controller first obtains the optimum voltage vector for each output port by minimizing the output current errors, where the ADR model generates the appropriate references. Finally, the controller identifies the optimum state from the determined voltage vector pair by minimizing the FC voltage errors. Unlike conventional MPC, the CMPC algorithm reduces the computational burden of the controller and attains multivariable control without additional control loops and weighting factors. Furthermore, the converter's performance with the CMPC algorithm is validated experimentally on a low-power hybrid microgrid.


Due to climate change and rapid urbanization, contemporary cities face the dual challenges of providing sufficient stormwater management and adequate park services, which potentially conflict over limited space and resources. To solve these problems, cities are increasingly combining stormwater infrastructure with park space in ways that create new efficiencies. To date, most research has focused on the stormwater management performance aspect of these combinations and not the techniques employed to achieve the combined goals. To fill this gap, 23 sponge city parks in Shanghai were investigated to examine the combination of stormwater and park services. Our findings show that stormwater techniques were primarily combined with the park facilities of water areas, paved open spaces, and pathways. Additionally, we found that larger parks employed a wider range of techniques for managing stormwater runoff and supported broader sets of park activities, while those at smaller scales prioritized infiltration, detention, and purification measures, as well as concentrated on social and economic activities. This study is the first to explore SPC parks that integrate stormwater management and park services, thereby providing implications for SPC development in China and insights into the ways that the two properties can be combined in other cities.


This article argues that the pause in whole school Ofsted inspections until the end of 2020, and possibly into 2021, offers the opportunity to re-examine the nature of school inspection as an appreciative process with inevitable limitations that Ofsted has so far failed to recognize. This raises the possibility of replacing the current adversarial system with a more consensual one grounded in basic principles similar to, but developed from, the process of school inspection pre-Ofsted by Her Majesty's Inspectorate of Schools.


Institutions are naturally seen as the stable and relatively fixed backbone of the social world. While the structural role of institutions is usually discussed in social ontology, the temporal implications of this regulation are often overlooked. It is indeed tempting to take a present-centred approach to institutions. The latter clearly are instrumental in stabilizing and structuring the social coordination between a number of actors. But it is all too easy to focus only on their role in syn...


By conducting surveys on the stress experienced by the present - times faculty, and analyzing the faculty' s present situation along with the features and definition of books' therapeutic service, the article proposes that it should be indispensable to publicize books' therapeutic service among the faculty in tertiary institutions and probes the advantages of books' therapy and the specific measures of its therapeutic service.


Warp drives have been used in popular fiction to describe vehicles that can travel at velocities beyond the speed of light. The science behind such devices is well established and can be used to determine how such devices might operate and can provide an estimate of when, if ever, such devices could be constructed. The Theory of General Relativity forms the basis for the concept of warp drives and can be used to proceed in a formal manner from the Schwarzschild solution for black holes, to Kip Thorne's concept for wormholes and on to Alcubierre's recent solution that is a fully functional warp drive. The physical and technical aspects associated with Alcubierre's warp drive solution are presented, and it is shown that the energy requirements are well beyond current technology.


Like reading a book, stories told orally or acted out auditory invite subjective co-construction of narrative events through imagination. While an interesting characteristic, audio-based, fictive storytelling is not well explored in HCI. Eavesdropper is a prototype system for Mixed Reality Audionarrative, the stage being a miniature house and the actors residing in a spatialized, virtual, audio world. This work accounts for development and evaluation of some contextually unconventional, properties of one current iteration of the system, aimed at facilitating an exploratory mindset: sections of the narrative unfolding in parallel, controlled by parameters the user is only partially aware of. Through qualitative evaluation with users, I report on how these properties affected the way a story world was experienced, explored and interpreted. The findings, coupled with reflections on the design choices made, are then synthesized to a set of design sensitivities meant to inform and spur discussion and further inquiry into similar systems exploring audio as the primary mean for conveying narrative.


Unlike several boom-and-bust fisheries of the last century, the recreational saltwater bass (Paralabrax spp.) fishery in southern California has endured oceanographic regime cycles and nearly a century of increasing anthropogenic impacts. We examined regulatory changes and several fishery-dependent and fishery-independent time series to determine historical influences on the fishery and causes of dramatic catch declines in recent years. Our results reveal a complex relationship between bass abundance and harvest rules, fishery recruitment, giant kelp (Macrocystis pyrifera), ocean regimes, and fishing. Recent trends in larval abundance and lengths of harvested fish suggest recruitment failure occurred during the last oceanographic regime shift coincident with a peak in exploitation rates. We believe this contributed to poor fishery recruitment, associated declines in catch-per-unit-effort, and a depressed population since the mid-2000s. Although long-standing regulations and periods of optimal environmental conditions appear to have sustained the fishery, we recommend an adaptive management approach to mitigate the effects of fishing pressure during unfavorable ocean conditions.


Few Brazilian cauliflower cultivars have shown to be adapted to tropical winter conditions. In addition, studies to obtain hybrids adapted to our winter conditions, from breeding lines originating from tropical regions, are scarce. The objective of this work was to estimate the combining ability of cauliflower breeding lines. The experiment comprised 38 genotypes, 36 hybrids from a partial diallel cross obtained by crosses between two groups of cauliflower lines: Group I (3 parents) and Group II (12 parents) and 2 commercial controls. We evaluated plant cycle, resistance to diseases, average curd mass, curd color, hollow stalk incidence, and overall evaluation. Additive genetic effects were more important than non-additive effects in the expression of these traits. No single parental line showed simultaneously the most favorable GCA values for all traits. The most promising hybrids were the combinations BR1 x TE6, BR1 x TE8, BR1 x TE12, BR2 x TE11, BR3 x TE6 and BR3 x TE7. The results of the choice of hybrids made by the method of independent culling levels reflect what it could be predicted by estimating GCA for cycle and average mass of the curd, reaffirming the importance of additive effects in the expression of these traits.


Magnesium in methanol is an effective reagent for the chemoselective reduction of peroxides, including ozonides. Mg/MeOH is significantly more reactive than Me(2)S or PPh(3) and somewhat more reactive than Zn/HOAc.


The Trans-European Transport Network (TEN-T) is one of the most important transport policies in the EU since 1990s'. Its aim is to connect and benefit all the member states in light of the common European interest. TEN-T is expected to contribute to the general 'territorial cohesion' objective of the EU, benefiting largely from the Cohesion Fund in practice. However, territorial cohesion is a rather vague and complex concept and its definition is still in debate. This fact poses a challenge to measure territorial cohesion and even greater one to evaluate the impacts of TEN-T, on territorial cohesion. In order to meet the EU's requirement in policy consistency and justify TEN-T's contribution to territorial cohesion to various stakeholders, analysing the relationship between TEN-T and territorial cohesion is highly relevant. . Therefore, the general goal of this study is to develop a method for measuring and evaluating territorial cohesion effects of a sub-network of the TEN-T, i.e. the trans-European rail network for passenger transport. This method tries to answer a main question: What effects can the trans-European rail network for passenger transport have on territorial cohesion at the EU scale? Integrating different perspectives about territorial cohesion from literature and policy documents and observations from participation in related workshops, this study analyzes territorial cohesion as a desire for regional balanced development in multiple-dimensions. Lacking-behind regions are meant to benefit more than non-lacking-behind regions from TEN-T to enhance territorial cohesion. According to previous studies, territorial cohesion is supposed to contain three dimensions: territorial efficiency, territorial quality and territorial identity. Concreting the three dimensions, the nine most relevant core issues have been identified: 1) Infrastructure endowment, 2) External accessibility, 3) Network efficiency for territorial efficiency; 4) Fair accessibility, 5) Environmental risk, 6) Sustainable transport for territorial quality; 7) Local identification, 8) Land and landscape, 9) Knowledge and innovation for territorial identity. The three dimensions and nine issues have become the criteria and sub-criteria in the method. The issues have been further developed into a set of corresponding indicators with data definitions. The method is operationalized through three phases to allow judging the territorial cohesion effects from transEuropean rail network. Phase evaluates basic territorial indicators on moments in time. Phase evaluates territorial impact through analysing change in the basic territorial indicators between two time points. Both phases generate figures and maps to analyze and visualize influence of trans-European rail network on individual regions. Phase analyses territorial impact results in terms of individual issues from Phase for different regional groups and comprehensively evaluates territorial cohesion effects at the EU scale. This study tests the developed method with available datasets for year 1996 and 2008 on 255 NUTS2 regions covering most territories in the EU. Although, due to data limitation, only eight of the nine issues have been implemented, this test has still proved that territorial cohesion effects from TEN-T at the EU scale can be measured, evaluated and judged through the shown method. Results from the test show that the trans-European rail network for passenger transport has general explicit but complex effects on territorial cohesion. At the general EU scale, territorial cohesion is either promoted or hampered in various extents in terms of different dimensions. This conclusion suggests more careful TEN-T policy to avoid serious conflicts between TEN-T development and the EU's territorial cohesion objective in some territorial issues. Largely limited by data and time, the proposed method certainly needs improvement from multiple aspects. Further study is suggested in 1) more discussion about indicators including relevant assumptions, thresholds, norms and classification; 2) deeper analyse in reasons resulting certain territorial impacts with sufficient consideration in local context; 3) development of packaged toolbox for easy method operation; 4) sensitivity analysis and noise analysis to increase method reliability and stability 5) operationalization of the method at regional scale


Results obtained with the g matrix are compared in detail with variational calculatins, by restricting both procedures to an oscillator basis consisting of the same maximum number of oscillator quanta. Three-body correlations are included in the g-matrix calculation by extending the basis of the hole states to include additional oscillator functions. The resulting formalism is similar to the Bethe-Faddeev equations, but the correlated wave function is presented in a way to make comparison with variational wave functions obvious. This comparison suggests a choice of potential in the particle states that yield a very small three-body correlation energy in /sup 3/H. Applications include the Sussex interaction and a singular short-range repulsion.


A standardized, accurate, and easy system is needed to describe Jerusalem artichoke (Helianthus tuberosus L.) plant development. Therefore, this study was designed to define stages of development descriptions for Jerusalem artichoke. Field experiments were conducted during early rainy season and the post rainy season of 2011 and 2012. Data were collected and uniform growth stage descriptions, based on visually observable events, were developed for the vegetative (V), reproductive (R) and tuberization (T) stages. The V stage was determined by counting the number of developed nodes on the main axis of the Jerusalem artichoke, beginning with emergence of the sprout seedling and ending with the initial visual appearance of the inflorescence. The proposed R stages include R1 (Floral bud formation), R2 (beginning bloom), R3 (flowering), R4 (beginning of anthesis), R5 (seed set) and R6 (seed maturity). The T stage include T1 (stolonization), T2 (tuber initiation), T3 (tuber formation), T4 (tuber bulking), T5 (skin set) and T6 (tuber maturity). The V, R and T stages can be measured separately and concurrently and apply to populations or single plants. The present study revealed that reproductive and tuberization development occurred more rapidly in the post-rainy season than in the early-rainy season. The proposed standard descriptions of Jerusalem artichoke development will help research and extension personnel better communicate results and recommendations related to this crop.


We discuss quiver gauge models with matter fields based on Dynkin diagrams of Lie superalgebra structures. We focus on A(1,0) case and we find first that it can be related to intersecting complex cycles with genus $g$. Using toric geometry, A(1,0) quivers are analyzed in some details and it is shown that A(1,0) can be used to incorporate fundamental fields to a product of two unitary factor groups. We expect that this approach can be applied to other kinds of Lie superalgebras;


Impaired renal function is associated with worse clinical outcomes in patients with LV systolic dysfunction (LVSD) and heart failure. Renin–angiotensin–aldosterone system (RAAS) inhibitors provide clinical benefit in these settings and often worsen renal function. It is not clear whether worsening renal function (WRF) in patients exposed to these agents predicts a worse prognosis or merely reflects the pharmacological action of the drug on the kidney.


Since the recession of 2008, there has been an increased scrutiny of higher education, with little research done on how this affects high school students' college search process. This study seeks to understand how college perceptions are formed and how they affect the college decision process of high school students in Sioux Falls, South Dakota. In order to gain a holistic perspective of this process, this study utilized a mixed method approach of analyzing public data, conducting interviews with community members and students, conducting a focus group with high school guidance counselors, and administering a survey to high school students. This study found that students in this area form their perceptions of college in three distinct phases and that these phases affect a student's college priorities. Special attention was given to how academics, cost and location contributed to a student's overall college decision. These findings can be used to assist faculty and staff at higher education institutions in creating effective messaging and programming that relate to this group of students.


I met Jurgen Habermas thirty years ago at around the time when he completed his Between Facts and Norms. In that book, Habermas defended a provocative thesis — the view that "in the age of a completely secularized politics, the rule of law cannot be had without radical democracy."1 I believe this view to be essentially correct and, with hindsight, would like to explore some of its key intellectual motivations that explain why this view remains relevant and provocative in contemporary discourse — but also add a challenge.


Given the widespread adverse outcomes of stress – exacerbated by the current pandemic – wearable sensing provides unique opportunities for automated stress tracking to inform well-being interventions. However, its success in the wild and at scale depends on the robustness and validity of automated stress inference, which is limited in current systems. In this work, we enumerate the properties of robustness and validity necessary for achieving viable automated stress inference using wearable sensors, and we underscore present challenges to constructing and evaluating these systems. Using these criteria as guiding principles, we present automated stress inference results from a large (N=606) in situ longitudinal wearable and contextual sensing study of information workers. Using a multimodal approach encompassing a wearable sensor, relative location tracking, smartphone usage, and environmental sensing, we trained regression models to predict daily self-reported perceived stress in a participant-independent fashion. Our models significantly outperformed baseline variants with shuffled stress scores and were consistent with small-to-moderate effects. Our findings highlight the performance disparity between robust and valid approaches to automated perceived stress inference and current approaches and suggest that further performance gains might require additional sensing modalities and enhanced contextual awareness than existing approaches.

We analyze the financing of an expansion project, as well as the pre-expansion capital structure decision. Using too much equity (debt) in the expansion financing results in under (over)-investment relative to the first-best (total firm value maximizing) policy. We identify the expansion financing packages that ensure first-best as well as second-best (optimal, or equity value maximizing) policies, and show that they are in general quite different. The optimal expansion financing package generally implies a significantly larger debt component than the first-best. With optimal expansion financing, the model's implications are consistent with empirical regularities such as (i) existing debt has a negative effect, while the debt component of expansion financing has a positive effect, on investment; (ii) the debt component of expansion financing is generally a decreasing function of the existing debt level, except for highly-levered firms; and (iii) the debt component of expansion financing is decreasing in growth opportunities. The ex-ante (pre-expansion) leverage ratio is also identified for both cases - first-best and second-best expansion financing. In the latter case, the model's implications are again consistent with empirical regularities: (i) growth opportunities have a negative effect on both book and market optimal leverage ratios; and (ii) optimal leverage ratio is negatively related to earnings or profitability. Overall, the available empirical evidence suggests that expansion decisions are usually second-best, i.e., made to maximize equity value rather than total firm value.


For example, the organic acid derived from an aromatic carboxylic acid-producing plants, such as terephthalic acid-containing waste water by treating the stream 12 to recover the alkali, and water for recycling to the manufacturing process.

Objective:To investigate the cytotoxic effects of PAP on leukemic cells in vitro.Methods:Six blood samples were collected from six patients who had been diagnosed as acute leukemia clinically. PAP were added into the culture system after culture began. The concentration of PAP in the culture system were 0.05g/L. We kept this concentration of PAP in the culture system for 24 hours in short term PAP administration experiment where leukemic cells would be counted in the 7th day. This concentration of PAP in the culture system were kept for 5 days in long term PAP administration experiment which would be stoped in the 7th, 10th, and 14th day respectively. These two experiments were designed controlly to measure the total cell counts, trypan-blue-exclusion rate, and trypan-blue-exclusion inhibition rate. The statistical comparisons between two groups were conducted through matched t tests. Results:PAP was of significant cytotoxic effects on leukemic cells in both PAP administration experiments. The influence of the prolongation of PAP administration period in the cytotoxicity of PAP towards leukemic cells was indefinite in the circumstance of 7-day culture. Trypan-blue-exclusion inhibition rates of leukemic cells were elevated significantly from 32.40%~69.50% to 94.10%~98.90% when culture period was prolonged from 7 days to 14 days, ie, the cytotoxicity of PAP towards leukemic cells was increased significantly. Regardless of refractory case or primarily resistant case, the cytotoxicity of PAP towards leukemic cells from these cases was not interfered. At the 14th day of culture the morphology of leukemic cells changed obviously in experiment group, but did not in control group. Some adherent cells grew in control group, but did not in experiment group. Conclusion:PAP is of significant cytotoxic effects on various leukemic cells and might become a broad spectrum anti-leukemic medicine.


10.1586/ERV.12.142 Scientists at Arizona State University (AZ, USA) have recently designed a universal platform for the delivery of potent DNA vaccines. The researchers have utilized re-engineered Salmonella bacteria to enhance delivery to host cells. The new experimental vaccine, described in the journal Proceedings of the National Academy of Sciences, which falls into a category termed 'recombinant attenuated Salmonella vaccines' (RASVs), has demonstrated complete influenza protection in mice and is hoped to be applicable to any infectious pathogen. The new orally administered vaccine has potential to be applied to the rapid manufacture of effective vaccines at a fraction of the cost of traditional methods and without risk to either those vaccinated or the public. Vaccine design is inhibited by the desire to generate a robust immune response but not at the expense of safety; as such, a compromise often needs to be made. The new research has worked to avoid this compromise by combining safety and effectiveness in techniques using Salmonella as a cargo vessel for disease antigens capable of provoking an intense, system-wide immune response and conferring effective immunity. Roy Curtiss (Arizona State University), an author of the study, explains further: "Here, we were able to deliver a vaccine whose DNA sequence induces the immunized individual to make the protective glycoprotein the way you would during a viral infection." Efforts to utilize bacteria for delivery of DNA vaccines date back to 1995; however, the breakthrough has only just been achieved despite the Arizona State University team working to achieve this over the past 5 years. The researchers at Arizona State University used recombinant Salmonella typhimurium strains that were attenuated yet capable of synthesizing protective antigens to develop the biological containment system. The S. typhimurium strains were designed to contain regulated delayed attenuation and programmed self-destructing features to efficiently colonize host tissues and allow release of the bacterial cell contents after lysis. The researchers modified the bacterium to also include a safety feature so that the strain can only survive on a nonnaturally occurring form of sugar supplied to them as part of the vaccine. "This crucial safety feature ensures that Salmonella are unable to persist as living organisms to survive if excreted into the environment," says Wei Kong (Arizona State University), another author on the study.


This study investigated the relationship between body dissatisfaction, eating disorder symptoms, and attentional bias to images of male bodies using a compound visual search task. Sixty-three male participants searched for a horizontal or vertical target line among tilted lines. A separate male body image was presented within proximity to each line. Overall, search times were faster when the target line was paired with a muscular or obese body and distractor lines were paired with bodies of average muscularity and body fat (congruent trials) than on neutral trials, in which only average muscularity and body fat images were shown. Attentional bias for muscular bodies was correlated with muscle dissatisfaction, eating restraint, and shape concern, and attentional bias for obese bodies was correlated with eating restraint. For incongruent trials, in which a single muscular or obese body was paired with a distractor line, search times were indistinguishable from neutral trials. Unexpectedly, we found a negative association between search times and both body fat dissatisfaction and eating disorder symptoms in conditions where obese bodies were paired with distracting stimuli. This result implicates a potential role for attentional filtering and/or avoidance of obese bodies in predicting body fat dissatisfaction and eating disorder symptomology.


SECTION 1 defines measures and sigma-fields. SECTION 2 defines measurable functions. SECTION 3 defines the integral with respect to a measure as a linear functional on a cone of measurable functions. The definition sidesteps the details of the construction of integrals from measures. SECTION *4 constructs integrals of nonnegative measurable functions with respect to a countably additive measure. SECTION 5 establishes the Dominated Convergence theorem, the Swiss Army knife of measure theoretic probability. SECTION 6 collects together a number of simple facts related to sets of measure zero. SECTION *7 presents a few facts about spaces of functions with integrable pth powers, with emphasis on the case p=2, which defines a Hilbert space. SECTION 8 defines uniform integrability, a condition slightly weaker than domination. Convergence in L1 is characterized as convergence in probability plus uniform integrability. SECTION 9 defines the image measure, which includes the concept of the distribution of a random variable as a special case. SECTION 10 explains how generating class arguments, for classes of sets, make measure theory easy. SECTION *11 extends generating class arguments to classes of functions.


ABSTRACT In Western modern book publishing, there existed "folk" books also known as chapbooks that were intended for grass-root readers. In the Ukrainian tradition, they were called lubok books. Ukrainians had no opportunity to study their national history at school in the Russian Empire, therefore, alternative channels of social communication, in particular, books were gaining importance. The article deals with the repertoire of lubok books that depicted events of the history of Ukraine. The repertoire has been analyzed by time, place and language of printing, as well as by thematic directions.


The effect of hydrostatic pressure on the quantum confined transition in CdSe/ZnSe single quantum wells grown by molecular beam epitaxy has been studied by low‐temperature photoluminescence measurements. Samples with layer thicknesses of CdSe from 1 to 4 monolayers were used. Strong excitonic emissions associated with the lowest Γ‐Γ interband transitions were observed in these highly strained quantum well samples. The pressure coefficients of the interband transitions are found to depend on well thickness with the numerical value decreasing as the well width increases. Pronounced sublinear pressure dependence of the excitonic emissions was observed in the samples with 3 and 4 monolayer CdSe wells, indicating the degradation of the samples due to strain relaxation. Our results suggest that the critical thickness for the CdSe layer pseudomorphically grown on ZnSe is less than 4 monolayers.


The resistance often early, ten medium late and ten late flowering ryegrass populations to two rates of dalapon (2.8 and 5.6 kg ha-1 acid equivalent) was measured in a box experiment. There was no difference in the mean effect of dalapon on the maturity groups at the time of greatest yield reduction, but the recovery of the late flowering population was, on average, better than that of the medium late group. There was a range of reaction to herbicide within all three maturity groups and, in general, the high yielding populations without dalapon were the most resistant, but there were exceptions. Assessment at 2.8 kg ha-1 acid equivalent gave a similar ranking order to that using twice the amount of dalapon. The results of the current box experiment with seedlings were consistent with those obtained in the field at another location (Faulkner, 1974) for the eleven cultivars common to both trials. The resistance of a permanent pasture population was much lower than that of some cuttivars.


A 59 year-old man without past medical history was referred with biochemical features of cholestasis (aspartate aminotransferase (AST) 117 U/L, alanine aminotransferase (ALT) 83 U/L, gamma-glutamyl transferase (GGT) 1307 U/L, alkaline phosphatase (AP) 1803 U/L, total bilirubin 0,7 mg/dL), a strongly positive antimitochondrial M2 antibody (AMA-M2) titer (88 U), weight loss and abdominal pain since several months. He did not take any medications, nor there was a history of alcohol abuse or sexual risk behavior. Upon presentation, clinical examination showed a rather cachectic patient (body mass index 19 kg/m²), without further abnormalities. As primary biliary cholangitis (PBC) was suspected, treatment with ursodeoxycholic acid had been initiated but did not improve the cholestasis nor the pain. Additional investigations didn't reveal any other irregularities, except for a mildly dilated aortic sinus root of 42 mm. The histopathological findings of a liver biopsy are shown below (Figure 1). This showed granulomas with cholangitis and increased presence of neutrophils, which raised suspicion for an infectious cause.


The present work was done in a private nursery under plastic conditions houses in Belbeis District, Sharkia Governorate (Egypt) during 2015 and 2016 seasons to study the effect of four mineral nitrogen, biofertilizer treatments and three culture media on seed germination (%), vegetative growth characters, fresh and dry weights, growth analyses and chemical composition of tomato transplants at 60 days from seed sowing. The obtained results showed that, the treatments of mineral nitrogen and biofertilizer, the culture media and their interactions recorded a significant effect in both seasons of study on most studied characters, but this effect was varied from treatment to another and from season to another.


According to the existing legislation the modern Russian Prosecutors Office executes two main activities. They are prosecutors supervision and criminal prosecution. The other functions mentioned in Part 2 Art. 1 of The Prosecutors Act are considered as derivative ones. For instance, the prosecutors coordination activity concerning delinquency control and trial case hearing participation can be supposed as separate prosecutors functions as long as they are implemented in the frames of prosecutors supervision and criminal prosecution. Thus all other prosecutors activities are executed in the frames of these two main functions. That is why the modern Russian Prosecutors Office is considered to belong to its own special type. It is called mixed because it has the features of the Prosecutors Office, which is obliged to execute only criminal prosecution; at the same time it has the features of the Prosecutors Office of the control type. The modern prosecutors supervision is an independent legal phenomenon, which differs from other forms of public monitoring. Today it is the only public control activity supposing the legal evaluation of the conduct of the maximum number of public agents. No doubt, as a kind of control activity it has some similar features with monitoring, but its purposes, destination, principles of organization and execution and forms of activity do not allow defining it as an ordinary form of public monitoring. Theoretically the Prosecutors Supervision category has two aspects. First of all, it is a separate form of prosecutors activity. Then, it is a complex of legal relations originated from this activity. Taking into account a low level of todays legal regulation using the definition of Prosecutors Supervision as a separate form of activity is more correct. The legal modification of the normative comprehension of zakonnost (lawfulness) led to a wider usage of the notion public interest. The main difference is in more intensive intervention in supervised agents conduct than it happened during traditional prosecutors monitoring. Ultimately this intervention is ensured by a trial application. Thus, step-by-step prosecutors monitoring during supervising has been getting the trial hearing form. Traditionally, prosecutors supervision is considered as a kind of informal way of legal application, which consists of several prosecutors procedures based on quasi-administrative and quasi-remedial methods of case solving. On the whole, the modern prosecutors supervision preserves this character. At the same time the enlargement of remedial content in its activity makes it operate with judicial methods of case solving more often. Thereupon, the arrangement of modern prosecutors supervising gradually stands closer to trial case hearing as a classic form of legal application. In that way this activity truly can be considered not as supervision itself, but as prosecutors process existing in different forms and consisting of several procedures.


Prefabricated utility tunnels have drawn much attention in relation to rapid urban development. On this, how to maintain the integrity of an underground lifeline, which is subjected to unexpected fault displacement action, is a concern either from the design or the construction aspect. By applying the commercial software program ABAQUS, this paper presents a systematic numerical simulation of a prefabricated utility tunnel affected by a reverse fault. The critical parameters investigated in this study include fault displacement, burial depth, utility tunnel-soil friction coefficient, and the angle of the utility tunnel crossing the fault plane. Results of the numerical modeling revealed that: (1) both the overall structural deformation and the spliced joints deformation of the prefabricated utility tunnel increase with increasing fault displacement, which greatly reduces the waterproofing ability of the utility tunnel joints; (2) the opening displacement of the joints on the roof of the utility tunnel near the fault plane is positively correlated with burial depth, but the variation is slight; (3) the variations in utility tunnel-soil friction coefficient have little effect on the overall structural deformation and the spliced joints deformation; (4) the opening displacement of the spliced joints of the utility tunnel basically gradually increases with an increase in the crossing angle near the fault plane, which is different than when it is away from the fault plane. The main outcomes obtained from this study can provide reference for the construction of prefabricated utility tunnel in fault active area.

ABSTRACT Incubation is a costly phase of avian reproduction, as parents must invest in heat transfer to eggs and nest construction in order to maintain egg temperature within suitable thermal limits; however, costs may differ based on an individual's ability to invest in reproduction. To investigate how environmental conditions, specifically food quality experienced during development and reproduction, influence tactics of resource allocation and costs during incubation, captive Zebra Finches (Taeniopygia guttata castanotis) were raised on either a high- or low-quality diet, paired with a bird of the same diet history, and randomly assigned to breed under the same diet they had been reared on or on the opposite diet. Data were collected on nest attendance, nest quality, nest temperature, and clutch performance (clutch size, egg weight, and number of hatchlings). Greater nest attendance and higher nest-quality scores predicted low temperature fluctuation. Three structural nest components also contributed to temperature maintenance. Temperature fluctuation was the only measure to predict whether or not one or more eggs hatched ("clutch fate"); thus, multiple factors interact to contribute to the outcome of a clutch. Allocation to clutch size and egg mass was influenced only by breeding diet, while nest quality was influenced only by natal diet. In contrast, nest attendance and nest temperature varied with both natal and breeding diets. Nest attendance patterns of birds that experienced a consistently high-quality food environment suggest they faced relatively lower reproductive costs and less sexual conflict than other treatments. Nest temperature patterns of birds raised in a high-quality food environment but bred on a low one suggest they faced higher reproductive costs and more sexual conflict. Thus, a good start in early life may be advantageous if conditions remain favorable, but could lead to higher sexual conflict and reproductive costs if food conditions deteriorate in adulthood.


Aimed at the limitations of clustering of the traditional calculation of similarity based on distance,a method of point-set clus-tering based on topology geometry-figure is proposed.Some kinds of objects with the geometric characteristics wishing to be needed are extracted from the discrete point-sets.The experiment shows that the method can detect effectively the curve points of small curvature,to some extent,it overcomes the limitation of the method based distance.It can be applied in the areas of engineering drawings recognition,computer vision,remote sensing recognition and so on.


In this paper, vector optimization problems with arbitrary domination sets are studied. Scalarization results for efficient and weakly efficient elements of these problems are proved, where especially Gerstewitz functionals and order unit norms are used. A surrogate for the weakly efficient point set is investigated, which is of special interest for domination sets with an empty algebraic interior. The study includes the consideration of perturbed problems. In general, we admit any linear space as image space of the vector optimization problem and do not assume convexity of the feasible point set or of the domination set. Nevertheless, several statements refer to the case that the domination set is an ordering cone. The results can be applied to determine optimal elements which are defined by relations, especially in decision making. Furthermore, they constitute a base for the systematic investigation of many scalarizing problems in multiobjective optimization. This is illustrated for the Hurwicz Rule in decision making under uncertainty.


The stability of a reservoir bank depends on the balance of forces,motive and resistive,associated with the most critical mechanism of failure.Many mechanisms are possible and the likelihood of failure occurring by any particular one depends on the geometry and structure of the bank,the engineering properties and vegetation of the bank material,the hydraulics of flow in the adjacent channel and climatic conditions.Bank geometry is the postulate,and it includes bank angle,bank height and bank profile.In this paper,Shibao town Zhongxian Country of Three Gorges section was taken for example,and then analysis the impact of reservoir bank geometry on the stability via BSTEM model.This will be help to study the risk of soil erosion of reservoir bank,and have a guiding role in prevention and control measures.


A finitely generated group [Formula: see text] acting on a tree with infinite cyclic edge and vertex stabilizers is called a generalized Baumslag–Solitar group (GBS group). We prove that a one-knot group [Formula: see text] is a GBS group if and only if [Formula: see text] is a torus knot group, and describe all n-knot GBS groups for [Formula: see text].


Objective: Diabetes, dyslipidemia and hypertension are increasing in prevalence worldwide and they are among the most cardiovascular factors. The aim of this work was to know the cardiovascular complications found in hypertensive patients with diabetes and dyslipidemia followed in nephrology consultation. Design and method: We conducted a descriptive retrospective study over a period of two years (January2020- January2022) including hypertensive patients aged over 18 years followed in nephrology consultation. Cardiovascular risk was estimated by calculating the Framingham score. The stage of chronic kidney disease (CKD) was defined according to the KDIGO 2012 classification. Results: Our study included 73 patients followed in our nephrology consultation for hypertension associated or not with nephropathy. The mean age was 69.62+/-9.59 [30-96] with a sex ratio M/F = 1.35. Diabetic patients were 44(60.27%) and dyslipidemic patients were 25 (34.24%). Diabetes associated with dyslipidemia were found in 21 patients (28.76%). Among the diabetic patients, hypertension was diagnosed before diabetes in 24 patients (54.54%) and it was considered as diabetic macro angiopathy in 20 patients (45.45%). Diabetic nephropathy was found in 32 patients (72.72%) and diabetic retinopathy in 20 patients (45.45%). The average Framingham score was (22.94%) and (21.52%) in diabetic and dyslipidemic patients respectively. Obesity was found in 15 patients of our population (20.54%), of which, 12 patients were diabetic (80%) and 7 patients were dyslipidemic (46.66%). Coronary artery disease was found in 14 patients in our population (19.17%) of whom 8 were diabetic (57.14%) and 3 were dyslipidemic (21.42%). Heart failure was found in 8 patients, 6 of whom were diabetic (75%) and 3 of whom were dyslipidemic (37.5%). Six patients in our population had a stroke (8.21%), 5 of whom were diabetic (83.33%) and 2 were dyslipidemic (33.33%). Regarding the renal impact, we noted the presence of chronic kidney disease stage 3 or more in 55 patients (75.34%) among which 19 patients had dyslipidemia (34.54%). Conclusions: We noted a multitude of cardiovascular events in patients with diabetes and/or dyslipidemia associated with hypertension. Early identification and management of these risk factors are necessary to prevent cardiovascular complications.


The satirical representation of the scholastic world is a recurring motif in Maurizio Cattelan's artistic production, since the beginning of his career, in the first part of the Nineties: from the point of view of the undisciplined and lazy student (with whom the artist identifies himself) the educational system is shown as a coercive and punishing entity which burdens individuals with compulsory, monotonous and senseless exercises (such as writing). Many different factors contribute to this negative portrait of schooling: the biographical experience of Cattelan himself as an unhappy pupil; the stereotypes about lazy students and their attitude towards educational institutions; an interest in schooling as a metaphor to describe the relationship between the artist and the art world. This analysis of Cattelan's most representative works inspired to the scholastic world aims to show how his self-description as a bad student can be read as a proposal of a new understanding of the artist's role within the art system.


Aim: The aim of this study was to describe the histological characteristics of altered human lingual frenulum. Materials and Methods: Between March and July, 2011, 50 children between 6 months and 4 years of age were assessed by a Speech Language Pathologist in a Public Health Care Service in Brotas - Sao Paulo, Brazil. The lingual frenulum evaluation protocol proposed by Marchesan (2010, 2012) was administered to the 50 children - 26 male and 24 female. Of the 50, 8 children had lingual frenulum alterations. The 8 children with lingual frenulum alteration underwent lingual frenectomy. The materials for analyses were taken from 7-micrometer-thick tissues sections. Staining was employed using haematoxylin paired with eosin (H&E), Masson's trichrome and picrosirius red. Results: The assessment of the lingual frenulum indicated that 8 children had lingual frenulum alteration. Surgery was performed and the material collected was submitted to analyses. The histological analyses demonstrated that the lingual frenulum of children with ankyloglossia or with short frenulum had bundles of striated skeletal muscle fibers, high frequency of type I collagen in the deep layers and compact bundles of elastic fibers positioned near the epithelial lining. Bundles of muscle fibers were not observed in anterior frenulum and short frenulum with anterior fixation. Type I collagen and bundles of elastic fibers sparse and far from the epithelial lining were observed in those types of frenulum. Conclusion: The analysis of the histological sections demonstrated the characteristics of altered human lingual frenulum.


in conjunction with materials on the web, with one additional chapter and a most useful 45-page bibliography to accompany the published volume. Although French transatlantic migration (including that to Canada) was considerably less than that of the British, Spanish, and Portuguese, Boucher points to "the relative economic success" (p. 8) of the French Caribbean colonies, particularly in the first two decades of settlement, and also notes that exports and imports from these islands greatly exceeded those of French Canada. Militarily, the French were successful vis-à-vis the British and Spanish through most of the century. In many ways, the French pattern of settlement resembled that of the British, with the early decades of settlement being predominantly of white labor, often indentured labor; with the primary crop being tobacco for export, and only later the plantation production of indigo, cotton, and ginger and, most importantly, sugar based on slave labor; and with much of the settlement based on relatively short-lived companies. Boucher argues that it is probable that slave and free living conditions in the islands (and Cayenne) were better in the French than in the British West Indies and were probably better in the seventeenth than in the eighteenth century, and that white living conditions were possibly more favorable in the Caribbean than in France. In regard to patterns of institutions and behavior in the colonies, he argues that "colonists made conscious cultural selections from a 'European menu,' but simplified rather than replicated old ways" (p. 143). Boucher has presented much detail about the process of settlement of the French Indies, and their development over time, paralleling somewhat the discussion of the French in the Americas between 1670 and 1730 by James Pritchard in his In Search of Empire (Cambridge: Cambridge University Press, 2004). France and the American Tropics to 1700 is an interesting and informative work and will be influential in discussions of France, the French Overseas Empire, and the expansion of slavery into the Americas.


Construction project is indeed a complex system, where many participants are involved and interact with each other. Risk interdependence brought up by interactions between participants is often ignored, which may lead to inaccurate risk assessment and inefficient risk management. This paper deals with the risk interdependence from a complex system's perspective. We first explained how the risk interdependence arises through the interaction between participants, to draw forth the idea of establishing an agent-based model to manage risks in construction project system. Then a framework using colored Petri nets (CPNs) to establish an agent-based model for construction project system was introduced. Its application to manage risks was also briefly illustrated. Further research is about to realize the CPNs models for the construction project system and put it into application. It is believed that studying the risk interdependence will be helpful to more accurate project risk assessment and better risk management.

We report a comprehensive theoretical investigation of ballistic quantum transport in monolayer black phosphorus (ML-BP) field-effect transistors (FETs). Our calculation is from tight binding atomistic model based on the nonequilibrium Green's function formalism. Several important device properties, including the drain current, ON-OFF ratio, transfer characteristic, short channel effects, intrinsic delay, and power delay product are determined against the channel length, transport direction, bias, and gate voltages. The atomistic simulation provides microscopic understanding of the device physics. Due to the anisotropic band structure of ML-BP, an orientation-dependent transport characteristic manifests itself in the major transistor properties. Comparing device performance in the zigzag and armchair direction (AD), we predict that transport along the AD has higher ON-state current and faster switching speed due to the lighter carrier effective mass. Comparing with ML MoS2 FET, ML-BP FET produces higher current density and faster switching speed, but costs more switching energy. Double gated ML-BP FETs show promising device characteristics that fulfill the international technology roadmap for semiconductors requirements in the 10-year horizon.


Abstract  We report the case of a female patient with bilateral metachronous adrenocortical cancer who survived long‐term after adrenalectomy. In 1991, the patient underwent left adrenalectomy to remove a huge adrenal mass (10 × 9 cm) displaying no hormonal abnormality. Histological diagnosis was adrenocortical cancer. A right adrenal mass (7 × 6 cm) was found 4 years after left adrenalectomy. Right adrenalectomy was performed, and histological diagnosis was again adrenocortical cancer. The patient remains alive with no evidence of disease 8 years after last surgery.


Adaptive optics allows imaging of individual photoreceptors in vivo and viewing of arbitrary stimuli nearly free of optical blur. Combining these abilities has created new opportunities to study the retinal and neural limits on vision.


The carbon nanotube (CNT) is a representative nano-material discovered in 1991 at NEC. With its unique structure, high strength, high electric conductivity and high thermal conductivity, CNT is expected to be applied widely together with its variant the carbon nanohom (CNH) in electronic devices such as transistors and fuel cells as well as in the environmental and biotechnological fields. This paper introduces the characteristics and features of CNT and CNH and describes some of their application fields.


To clarify the host-virus relationship in polyoma virus infection, virus from a single culture pool was inoculated intravenously into AKR and cm mice and Fl hybrids within 24 hours after birth. Half the mice were thymectomized 2 weeks later. A high sensitivity of AKR mice to polyoma virus infection was shown in terms of the cumulative mortality, and of the incidence and mean latent period of parotid tumor growth in animals that survived more than 60 days. Thymectomy delayed significantly the death of infected mice in the AKR strain, but not in the C3H strain. The incidence and latency of parotid tumors were not affected by thymectomy in these strains of mice. High sensitivity to polyoma virus, the ameliorating effect of thymectomy, and predisposition for leukemia were observed in Fl hybrids whose mothers were AKR mice, but not in those whose mothers were C3H mice. It is concluded that there is a close correlation between the predisposition of AKR mice for leukemia and their sensitivity to polyoma virus infection, and that the thymus gland is partly, if not entirely, responsible for the high sensitivity. The incidence of leukemia was not significantly affected by the presence of polyoma virus infection.-J Nat Cancer Inst 30: 225-239,1963.


Conflicts over the status of Sharia Islamic law have dominated constitutional politics and ethno-religious relations in the Nigerian federation for decades. The adoption of stringent Sharia codes by 12 Muslim majority states in northern Nigeria, beginning with Zamfara in 1999, was particularly contentious, provoking broad concerns about the viability and survival of Nigeria's innovatively structured multi-ethnic federal system. But Sharia implementation and extension in Nigeria have followed a largely benign trajectory. The Nigerian federation's judicious combination of centrist and autonomy mechanisms has been remarkably effective in managing religious conflict and cauterising potentially disintegrative centrifugal challenges to national stability.

In this paper, we proposed a computer-aided diagnosis system based on SVM and Adaboost classification methods to achieve liver cirrhosis grading automatically. We first built two sample sets, one of which was directly obtained from the original abdominal CT images, and the other was processed through a series of preprocessing steps, including liver region segmentation, region of interest extraction and normalization. Then we labeled each patient's CT image according to their clinical diagnosis data based on Child-Pugh Score. Finally, we designed classifiers and probability statistics model to achieve liver cirrhosis grading. The feature of this paper is that the random selected local area image data set is used as the feature vector set, and the corresponding weight and probability model are introduced to carry out the statistical prediction. The classification results were evaluated with sensitivity, specificity and accuracy. The experimental results indicate the feasibility of the system with an accuracy rate over 98%. Through further training and learning, the system can assist doctors in the diagnosis of liver cirrhosis.


The toxicological response of the honey bee, Apis mellifera L., to DDT and other selected insecticides was studied, using the topical application technique. Results of these studies indicate the following: (1) Bees caged individually after treatment with DDT required a greater amount of toxicant to achieve the same response than when caged in groups of 15. (2) DDT was more toxic to workers, queens, and drones held at a post-treatment temperature of 70°F than at 80°F. (3) Tests conducted with bees caged individually at 70°F after treatment were more reproducible than those conducted at 80°F. (4) Under the conditions tested, 2- and 8-day-old bees were more susceptible to DDT than those 4 or 6 days old. (5) Under the conditions tested, insecticides applied to the dorsum of the abdomen gave essentially the same response as when applied to the dorsum of the thorax. (6) A toxaphene-DDT (2:1) mixture exhibited synergistic action at 80°F. (7) All colonies tested, including colonies started from gravid queens from the California colonies reported as DDT resistant (Atkins and Anderson 1962, J. Econ. Entomol. 56, 442–4) gave similar responses to DDT. (8) Resistance to DDT was not increased by 2 generations of selection.


To develop a new class of stellarators that exhibit improved confinement compared to conventional stellarators. This approach generally makes use of a designed symmetry of the magnetic field strength along a particular coordinate axis in the toroidal geometry of the stellarator, and is referred to as quasi-symmetry.

An air quality control was developed and tested in four single family passive house dwellings to control the building ventilation system via VOC sensors and a special adaptation algorithm to handle variable contaminant loads and sensor drift. Results show good operation of the air quality control for the ventilation system detecting changing contaminants within a few minutes and changing the air flow rate in the building immediately. The 43 VOC sensors used during the monitoring had more than 1.2 million working hours in total without any electrical failure but with a loss of sensitivity for the calibration gas CO. The air quality control could manage that loss of sensitivity and worked well till the end of the field test. A comparison between VOC and CO2 sensors in one building resulted in a more detailed information about emission rate in the room with the VOC sensor, allowing to get a better reaction of the ventilation system.


In this paper, we present the findings of a comparison study using predictive 'detailed simulation models for three different network protocol access methods: Carrier Sense Muttiple Access with Collision Detection (ANSIIIEEE 802.3 STD), Token-Passing Bus Access (ANSI/IEEE 802.4 STD) and Token-Ring Access (ANSIIIEEE 802.5 STD). Discussions of network performance, the implications of the resutts of the comparison study, and the insight gained from this project for improving real-time simulation networking are presented. INTRODUCTION A local area network (LAN) is a geographically confined communication system that uses a shared transmission medium. Various choices usually exist for the main ingredients of LAN (Le., transmission medium, topology, access protocols, etc.), with each exhibiting advantages and providing benefits that depend on the objectives of the LAN. The ability to model, analyze and evaluate the impact of these choices on network performance is essential to ensuring maxiDJum utilization of the LAN. One of the pioneering LAN's for ~. connecting computers was a bus-based .. ETHERNET developed by Xerox Corp. in the early 1970's. The contention access method used by each node in ETHERNET is based on a pre-emptive protocol of first listening for network activity and then broadcasting the message onto the network. If a collision with another message ocqurs, each sender (node) backs-off from transmitting their message for a random period of time and then attempts the transmission again. This access technique is known as Car:rier Sense Multiple Access with Collision Detection (CSMNCD) [1, 2]. Standards for CSMNCD protocols such as ETHERNET are known as IEEE 802.3 standards approved by the American National Standards Institute (ANSI). The networking of real-time, interactive simulation training systems departs from the traditional use of a computer network whose function is to provide sharing of computing resources among muttiple users (nodes) on the network. When used to interconnect real-time training simulators, the network is used almost exclusively for communication of process state information between the simulators engaged in the training exercise. There are many inherent limitations to using a network in this application. For example, as the number of simulators on the


In this research we propose the application of a multi-criteria decision analysis to make documented and transparent decisions about software measures' selection. The Pareto's dominance method was utilized to narrow down the initial measures' list. The multi-attribute value theory was applied for ranking the final set of measures. As a result there was eliminated about 40% of the initial measures and the final measures' list was ranked.


Chemically fueled emulsions are solutions with droplets made of phase-separated molecules that are activated and deactivated by a chemical reaction cycle. These emulsions play a crucial role in biology as a class of membrane-less organelles. Moreover, theoretical studies show that droplets in these emulsions can evolve to the same size or spontaneously self-divide when fuel is abundant. All of these exciting properties, i.e., emergence, decay, collective behavior, and self-division, are pivotal to the functioning of life. However, these theoretical predictions lack experimental systems to test them quantitively. Here, we describe the synthesis of synthetic emulsions formed by a fuel-driven chemical cycle, and we find a surprising new behavior, i.e., the dynamics of droplet growth is regulated by the kinetics of the fuel-driven reaction cycle. Consequently, the average volume of these droplets grows orders of magnitude faster compared to Ostwald ripening. Combining experiments and theory, we elucidate the underlying mechanism, which could help better understand how cells regulate the growth of membrane-less organelles.

Eleven compounds were isolated from the hot water extract of aerial parts of Schnabelia tetradonta by normal and reversed silica gel column chromatography.Their structures were identified as β-sitosterol(1),4-acetylaminoethyl-phenyl 6-O-methylcoumaroyl-β-D-glucopyranosyl(1→2)[β-D-glucopyranosyl(1→3)]-α-L-rhamno-pyranoside(2),4-acetylaminoethylphenyl 6-O-p-methylcoumaroyl-β-D-glucopyranosyl(1→2)[β-D-glucopyranosyl(1→3)]-4-O-acetyl-α-L-rhamnopyranoside(3),6-C-β-L-arabinopyranosyl-8-C-α-L-arabinopyranosylapigenin(4),6,8-di-C-α-L-arabinopyranosyl-apigenin(5),acetylmartynoside B(6),isomartynoside(7),alyssonoside(8),leucosceptoside B(9),forsythoside B(10) and butanedioic acid(11),respectively,on the basis of spectral methods.


Despite the introduction of Highly Active Antiretroviral Therapy (HAART), opportunistic skin diseases continue to be prevalent and persistent in human immunodeficiency virus-infected individuals. Patients in this study were already receiving antiretroviral therapy for more than 2 years presented clinically with skin malaise previously treated unsuccessfully with conventional antifungal and chemotherapeutic agents. An exit pool system where patients consented to be involved in the study was applied.

Robotic systems offer an attractive solution for a large spectrum of real-world applications that are hosted in dangerous or inaccessible areas for humans. In such applications, one of the fundamental tasks is to detect and mark particular features (e.g., pollution areas) in order to develop a proper response. In this paper, we focus on the specific problem of environmental edge detection using a swarm of homogeneous robots that can sense and act distributively using a large number of individuals. In our study, we consider both static and dynamic 2D environments, in which the spatial distribution of the feature(s) may change over time. We verify our results using a set of physics-based simulations.


Under the preview of quality, the word Quality means the best quality performance for customer's utmost satisfaction within a competitive price structure. Textile Testing & Quality Control (TTQC) is very important work or process in each department of export oriented industry. The study of the quality of terry towel fabrics will reveal new approaches. The terry-structured fabrics, used in bathroom, pool, sea, sauna and Turkish bath, hold an important place in people's personal lives as end-products. The methods of quality testing of the terry-woven fabric structure are discussed in this study. In the process of sample production, the towels were made on a loom and standard finishing techniques were applied. The comfort parameters of the gray and finished fabrics such as airpermeability, velocity of water absorption, and vapor permeability were measured under standard laboratory conditions and the obtained data were evaluated statistically. INTRODUCTION The testing of quality of textile products is an expensive business. A laboratory has to be set up and furnished with a range of test equipment not just when results are required. Moreover all these costs are non productive and therefore add to the final cost of the product. Therefore it is important that testing is not undertaken without adding some benefit to the final product. There are a number of points in the production cycle where quality testing may be carried out to improve the product or to prevent sub-standard merchandise progressing further in the cycle. Reasons for Textile Testing  Checking Raw Materials  Monitoring Production  Assessing the Final Product  Investigation of Faulty Material Checking Raw Materials The production cycle as far as quality testing is concerned starts with the delivery of raw material. If the material is incorrect or sub-standard then it is impossible to produce the required quality of final product. These processes are very often carried out in separate establishments; therefore what is considered to be a raw material depends on the stage in processing at which the testing takes place. It can be either the raw fibre for a spinner, the yarn for a weaver or the finished fabric for a garment maker. The incoming material is checked for the required properties so that unsuitable material can be rejected or appropriate adjustments made to the production conditions. The standards that the raw material has to meet must be set at a realistic level. If the standards are set too high then material will be rejected that is good enough for the end use, and if they are set too low then large amounts of inferior material will go forward into production. International Journal on Textile Engineering and Processes, ISSN: 23953578, Vol 1, Issue 1, Jan2015 49 Monitoring Production Production monitoring, which involves testing samples taken from the production line, is known as quality control. Its aim is to maintain, within known tolerances, certain specified properties of the product at the level at which they have been set. A quality product for these purposes is defined as one whose properties meets or exceeds the set specifications. Besides the need to carry out the tests correctly, successful monitoring of production also requires thecareful design of appropriate sampling procedures and the use of statistical analysis to make sense of the results. Assessing the Final Product In this process the bulk production is examined before delivery to the customer to see if it meets the specifications. By its nature this takes place after the material has been produced. It is therefore too late to alter the production conditions. In some cases selected samples are tested and in other cases all the material is checked and steps taken to rectify faults. For instance some qualities of fabric are inspected for faulty places which are then mended by skilled operatives; this is a normal part of the process and the material would be dispatched as first quality. Investigation of Faulty Material If faulty material is discovered either at final inspection or through a customer complaint it is important that the cause is isolated. This enables steps to be taken to eliminate faulty production in future and so provide a better quality product. Investigations of faults can also involve the determination of which party is responsible for faulty material in the case of a dispute between a supplier and a user, especially where processes such as finishing have been undertaken by outside companies. Work of this nature is often contracted out to independent laboratories that are then able to give an unbiased opinion. Product Development and Research In the textile industry technology is changing all the time, bringing modified materials or different methods of production. Before any modified product reaches the market place it is necessary to test the material to check that the properties have been improved or have not been degraded by faster production methods. In this way an improved product or a lower-cost product with the same properties can be provided for the customer. A large organisation will often have a separate department to carry out research and development; otherwise it is part of the normal duties of the testing department. Basic Parameters of Quality Terry Towel  Weight & GSM: Weight and GSM should be same as required by customer. Every manufacturer has some template or software (ERPs) where towel manufacturers calculate everything likes pile's height, density of picks and ends to meet requirement. This database or any software has been developed through some basic calculation.  Softness/ Hand feel: It depends on properties of the yarn used in pile, finishing chemicals and too some extent on pile orientation. International Journal on Textile Engineering and Processes, ISSN: 23953578, Vol 1, Issue 1, Jan2015 50  Pile Orientation: Totally depends on process line.  Lint: Lint is basically protruding fibers present in a finished towel. It is measured by weight of accumulated fiber collected from washing machine and tumble drying machine during testing.  Absorbency: Terry towel should be highly water absorbent.  Dimensional Stability: How a towel is behaving after washing is fall under dimensional stability properties. Dimensional stability is measured by the residual shrinkage % in a finished towel.  Other Parameters are strength, color fastness etc. METHODS The conditioning and testing of textiles instances where such conditioning is specified in a test method. Because prior exposure of textiles to high or low humidity (65 +/2 %.) may affect the equilibrium moisture pick-up, a procedure also is given for preconditioning the material when specified. The equipment to be used in the conditioning and testing of textiles shall include conditioning room or chamber, preconditioning cabinet, room, or suitable container, balance, and multiple shelf conditioning rack. The conditioning room or chamber shall consist of equipment for maintaining the standard atmosphere for testing textiles throughout the room or chamber within the tolerances given and including facilities for circulating air over all surfaces of the exposed sample or specimen and equipment for recording the temperature and relative humidity of the air in the conditioning room or chamber. Samples or specimens requiring preconditioning shall be brought to relatively low moisture content in a specified atmosphere. Samples or specimens requiring conditioning shall be brought to moisture equilibrium for testing in the standard atmosphere for testing textiles, or when required. Water Absorption Test: This is most important test carried out for terry towel. Main use of terry towel is to absorb the water after bathing. So to check the water absorbency is necessary. This test method determines the ability of a terry fabric to rapidly absorb and retain liquid water from surfaces such as human skin. The sample to be tested is mounted on an embroidery ring with just sufficient tension for removing the wrinkles in the fabric. It is placed below burette with the tip of the burette not more than 2.5cm above the fabric. The fabric is placed horizontally. The burette is filled with distilled water up to the zero mark. A drop of water is then allowed to fall on the fabric and the same time a stop watch is started. The drop is viewed at a low angle and as soon as the light from the drop vanishes, the stop watch is stoppedand the time in seconds is noted. The test is repeated in other portions of the same towel ten times and average is calculated. The time so calculated is recorded as the absorbency of fabric. Dimensional Stability Test: To determine dimensional change of the towel comparing the distances between length and width direction benchmarks before and after when subjected to an International Journal on Textile Engineering and Processes, ISSN: 23953578, Vol 1, Issue 1, Jan2015 51 appropriate combination of specified washing & drying procedure.ECE (European Colorfastness Establishment) detergent (without BOA), sodium per borate tetra hydrate used.Lay the towel to relax for 4 hours on a bench in ambient conditions so that it is smooth & tension free. Select the correct programmed for the wash required depending on the type of machine being used, set temperature, water levels. Dissolve the powder with a small quantity of warm water in a beaker and start the machine. Tumble dryer used to dry the towel. Fastness Properties of Terry Towel: Fastness there is resistance of dyeing and prints to external influences, is having importance for the practical use of any dyestuff. Fastness property tests are consequently very extensive and widely standardized. Technical committee 38, subcommittee of the International Standards organisation (ISO) has to date defined 45 different methods. The purpose for which for which a dyed material is to be used must always be born in mind when dyestuffs are selected. The evaluati


In many real-world applications such as airliner, railway, and satellite systems, operation of missions often involves multiple tasks or phases that must be accomplished in sequence. During each phase, some equipments may play different roles and subject to different environmental conditions. Thus, the system configuration, success criteria, and component behavior may change from phase to phase. This kind of systems are commonly termed as the phased-mission systems (PMS) . A typical example of PMS is the monitoring system in the satellite-launching mission which involves the launching, separation, and orbiting phases. Some equipments, such as the ground-station radars, may suffer from increasing stresses in the separation phase and becomes idle in other phases. Because of the dependence problem, the reliability of PMS is not the product of reliabilities of individual phases. Hence, the reliability analysis of PMS is more complex than that of the single-phase systems. Over the past four decades, substantial progress has been made in the reliability analysis of PMS [3]. Basically, existing methodologies can be categorized into the simulation and the analytical methods. The main advantage of the simulation methods [6, 19, 25] is their wide applicability to a variety of scenarios, while the strength of the analytical approaches lies in the accuracy of algorithm results. The analytical approaches can be further classified into the state-based, the combinatorial, and the modular methods. Typical state-based methods, such as the Markovian models [1, 4, 28, 31], are commonly used to analyze the PMS with repairable components. A commonly known challenge facing the state-based methods is the state explosion problem when the number of components becomes large. On the other hand, the binary decision diagrams (BDD) based methods [2, 15, 16, 18, 22, 27, 29, 30] (belong to combinatorial methods) are efficient for the PMS with many components. However, BDD based methods can suffer a similar explosion problem (node or path explosion) when the number of phases becomes large. This problem is known as the BDD explosion in the PMS analysis. The modular methods [13, 14, 21, 24, 25], which integrate the state-space and the combinatorial methods, are efficient in analyzing the PMS with a multitude of repairable components.

The following article discusses modern Iranian foreign relations in the Middle East and North Africa from the rise of the Safavid dynasty up to the fall of the Pahlavi dynasty. It looks at the interplay of nationalist and ultra-nationalist variables. The nationalist factors include the beliefs system of the policymakers, interests related to political survival, the political economy, the geopolitics of modern Persia and also the geographical realm. The transnational variables consist of the global order, symmetrical and asymmetrical interdependence, and the regional systemic status. These major components are vital in modern Persia's relationships with the regional and extra-regional players in the Middle East. Unlike the Iranian negative or conflictual dialectics, the Iranian positive or cooperative dialectics is the major consequence of the agent–structure's interactions in this region.

To identify the four typical faults of dry-type transformer winding insulations, looseness, deformation and eccentricity, this study establishes the electric magnetic force multi-physical field simulation model of a dry-type transformer winding under the four typical faults with COMSOL software, based on the vibration mechanism of an SCB10-1000/10 dry-type transformer. Through the multi-physical field coupling calculation, the comparative relationship between the vibration acceleration of the winding under the four kinds of faults and the normal working state is obtained. The results show that the amplitude growth rate of the fundamental frequency or harmonic frequency of the acceleration signal under four kinds of faults is different from that under normal conditions. Therefore, the threshold value of the fundamental frequency or harmonic increment of the acceleration signal is introduced to describe the growth rate of the acceleration signal relative to normal conditions. Finally, four typical faults are identified with different threshold ranges of acceleration increment under faults, laying a foundation for the fault diagnosis of transformer winding vibrations.
