I am honored to be here with you this afternoon, particularly because we are here in the memory of such an esteemed educator as Dr. Charles H. Thompson. I have been asked to speak to you about the challenges we face educating the children of our multicultural society. First, I will talk about some of the ways that schools place culturally diverse children at risk. Then, I will detail what I view as necessary to address the problem. I must, however, begin with a precautionary note: Even though we are talking today about culture, it is important to remember that children are individuals and cannot be made to fit into any preconceived mold of how they are "supposed" to act. The question is not necessarily how to create the perfect "culturally matched" learning situation for each ethnic group, but rather how to recognize when there is a problem for a particular child and how to seek its cause in the most broadly conceived fashion. Knowledge about culture is but one tool that educators may make use of when devising solutions for a school's difficulty in educating diverse children.


Wilms' tumor (nephroblastoma) is the most common renal tumor that occurs in children, accounting for 6% to 7% of all childhood tumors. However, it is extremely rare in adults, and the clinical course of adult Wilms' tumor is very aggressive. In addition, adult Wilms' tumor has a worse prognosis compared with Wilms' tumor that occurs in children. To date, there are no defined treatment protocols for adults. Here, we report the treatment course for recur- rence and lung metastasis of giant adult Wilms' tumor in a case of 33-year-old male, review the literatures for the treat- ment outcome and discuss the treatment course of this case retrospectively.


We discuss cooling efficiency for different-species Fermi-Bose mixtures in magnetic traps. A better heat capacity matching between the two atomic species is achieved by a proper choice of the Bose cooler and the magnetically trappable hyperfine states of the mixture. When a partial spatial overlap between the two species is also taken into account, the deepest Fermi degeneracy is obtained for an optimal value of the trapping frequency ratio. This can be achieved by assisting the magnetic trap with a deconfining light beam, as shown in the case of fermionic 6Li mixed with 23Na, 87Rb, and 133Cs, with optimal conditions found for the not yet explored 6Li-87Rb mixture.


Many years after online social networks exceeded our collective attention, social influence is still built on attention capital. Quality is not a prerequisite for viral spreading, yet large diffusion cascades remain the hallmark of a social influencer. Consequently, our exposure to low-quality content and questionable influence is expected to increase. Since the conception of influence maximization frameworks, multiple content performance metrics became available, albeit raising the complexity of influence analysis. In this paper, we examine and consolidate a diverse set of content engagement metrics. The correlations discovered lead us to propose a new, more holistic, one-dimensional engagement signal. We then show it is more predictable than any individual influence predictors previously investigated. Our proposed model achieves strong engagement ranking performance and is the first to explain half of the variance with features available early. We share the detailed numerical workflow to compute the new compound engagement signal. The model is immediately applicable to social media monitoring, influencer identification, campaign engagement forecasting, and curating user feeds.


Results of classical trajectory calculations on the adsorption of H atoms to amorphous solid water (ASW) ice, at a surface temperature Ts of 10 K are presented. The calculations were performed for incidence energies Ei ranging from 10 to 1000 K, at random incidence. The adsorption probability Ps can be fitted to a simple decay function: Ps = 1.0e −Ei(K )/300 . Our calculations predict similar adsorption probabilities for H atoms to crystalline and ASW ice, although the average binding energy Eb of the trapped H atoms calculated for ASW of 650 ± 10 K is higher than that found for crystalline ice of 400 ± 5 K. The binding energy distributions were fitted to Gaussian functions with full width half-maximum of 111 and 195 K for crystalline and amorphous ice surfaces, respectively. The variation of the H atom binding sites in the case of the ASW surface leads to broadening of the distribution of Eb compared to that of crystalline ice. We have also calculated the 'hot-diffusion' distance travelled by the impinging atom over the surface before being thermalized, which is found to be about 30 A long at Ei = 100 K and increases with Ei. The diffusion coefficient D of thermally trapped H atoms is calculated to be 1.09 ± 0.04 × 10 −5 cm 2 s −1 at T s = 10 K. The residence time τ of H atoms adsorbed on ASW is orders of magnitude longer than that of H atoms adsorbed on crystalline ice for the same ice Ts, suggesting that H2 formation on crystalline and non-porous ice is quite limited compared to that on porous ice. This is in good agreement with the results of experiments on H2 formation on porous and non-porous ASW surfaces. At low Ts, the long values of τ , the high values of D and the large hot distance travelled on the ASW surface before trapping the impinging H atom ensure that Langmuir‐Hinshelwood and hot-atom mechanisms for H2 formation will be effective. The data presented here will be important ingredients for models to describe the formation of H2 on interstellar ices and reactions of H atoms with other species at the ice surface.


The invention relates to a modular generation method for a multi-waveform radar signal, which belongs to the technical field of radar frequency synthesis and is applied to the design of a direct digital frequency synthesis (DDS)-based frequency synthesizer. A multi-waveform radar signal module consists of modular software, a field programmable gate array (FPGA) and DDS chips. The modular software comprises a man-machine interactive interface and a modular serial port timing module, wherein the man-machine interactive interface performs relevant operation and storage of control parameters and waveform data of the DDS chips and performs data communication with the FPGA; and the modular serial port timing module generates modular serial port control timing which is suitable for the DDS series chips and completes data acquisition and updating by computer communication. The FPGA is provided with a random-access memory (RAM), a universal asynchronous receiver/transmitter (UART) and a DDS control module, and realizes the functions of data communication with a computer and the storage of the control parameters and waveform data of the DDS chips and DDS chip control. The DDS chips output various signals set by the parameters under the control of the FPGA. The modular software developed by the method configures different DDS chips, so various radar signals of point frequency, linear frequency modulation, nonlinear frequency modulation and phase encoding can be generated, and the software supports on-line programming and the real-time updating of the control parameters and waveform data of the DDS chips.


Although Bohmian mechanics has attracted considerable interest as a causal interpretation of quantum mechanics, it also possesses intrinsic heuristic value, arising from calculational tools and physical insights that are unavailable in "standard" quantum mechanics. We illustrate by examining the behavior of Gaussian harmonic oscillator wave packets from the Bohmian perspective. By utilizing familiar classical concepts and techniques, we obtain a physically transparent picture of packet behavior. This example provides, at a level accessible to students, a concrete illustration of Bohmian mechanics as a heuristic device that can enhance both understanding and discovery.


Summary The computer revolution together with educational expansion has led to dramatic changes in the structure of the workforce and in the organisation of workplaces in the last four decades. These developments should have different impacts on the use of vocational and general skills. This study compares depreciation rates of general and specific training capital among West German workers between 1979 and 1999. In this time the personal computer entered the workplaces and the share of workers with a university degree doubled. Econometric estimates based on respondent's subjective ratings of the share of training skills applied to the current job indicate that depreciation rates of vocational skills increased significantly. In contrast, there is no evidence for positive depreciation rates among university graduates with general training capital at all. The role of measurement errors in respondent's ratings for the estimated depreciation rates is analysed with sensitivity tests. The findings lend some support to the view that there is obsolescence of vocational skills in times of rapid technological change and educational expansion.


Topological asymptotic expansions for quasilinear elliptic equations, such as the p-Laplace equation, have not been studied yet. Such questions arise from the need to apply topological asymptotic methods in shape optimization to nonlinear elasticity equations as in imaging to detect sets with codimensions $\geq 2$ (e.g. points in 2D or curves in 3D). In Part I our main contribution is to provide topological asymptotic expansions for a class of quasilinear elliptic equations, perturbed in non-empty subdomains. The topological gradient can be split into a classical linear term and a new term which accounts for the nonlinearity of the equation. Comparing with steps carried out to obtain such expansions for the Laplace equation, it turns out that for the p-Laplace equation, one key point lies in the ability to define the variation of the direct state at scale 1 in R^N. Accordingly we build dedicated weighted quotient Sobolev spaces, which semi-norms encompass both the L^p norm and the L^2 norm of the gradient in R^N. Then we consider an appropriate class of quasilinear elliptic equations, to ensure that the problem defining the direct state at scale 1 enjoys a combined p- and 2- ellipticity property. The asymptotic behavior of the solution of the nonlinear interface problem in R^N is then proven. An appropriate duality scheme is set up between direct and adjoint states at various stages of approximation. Part II deals with estimates and asymptotic expansions of condenser p-capacities and focuses on obstacles with empty interiors and with codimensions $\geq 2$. After preliminary results, we introduce equidistant condensers to study the case of segments. The anisotropy caused by a segment in the p-Laplace equation is such that the Polya-Szego rearrangement inequality for Dirichlet type integrals yields a trivial lower bound. Moreover, when p > N, one cannot build an admissible solution for the segment, however small its length may be, by extending the case of a punctual obstacle. We provide a lower bound to the N-dimensional condenser p-capacity of a segment, by means of the N-dimensional and of the (N −1)-dimensional condenser p-capacities of a point. The positivity cases follow for p-capacities of segments. Our method can be extended to obstacles of higher dimensions and with codimension $\geq 2$. Introducing elliptical condensers, we show that the topological gradient of the 2- capacity is not an appropriate tool to separate curves and obstacles with non-empty interior in 2D. One way out could be to consider different values of parameter p or to consider the second order of the topological expansion, i.e. the topological hessian.


The strain relaxation in In0.25Ga0.75As and In0.4Ga0.6As grown on GaAs substrates at low temperature has been studied before and after laterally oxidizing an underlying Al0.98Ga0.02As layer. The relaxation as a function of layer thickness has been measured by cross-sectional transmission electron microscopy and x-ray analysis. It is found that oxidation of the Al0.98Ga0.02As layer improves the relaxation of the strained InxGa1−xAs layer. Moreover, the interfacial misfit dislocations have been removed, and the threading dislocation density has decreased approximately by one order of magnitude after oxidation.

It gives me great pleasure to have the opportunity to join my colleagues John Bardeen and Leon Cooper in discussing with you the theory of superconductivity. Since the discovery of superconductivity by H. Kamerlingh Onnes in 1911, an enormous effort has been devoted by a spectrum of outstanding scientists to understanding this phenomenon. As in most developments in our branch of science, the accomplishments honored by this Nobel prize were made possible by a large number of developments preceding them. A general understanding of these developments is important as a backdrop for our own contribution.


Recent studies on sorghum [Sorghum bicolor (L) Moench] showed that episodes of high-temperature stress around anthesis could adversely affect grain yield via effects on pollen germination with varying responses among genotypes. The objectives of this study were to determine the reproductive development phase most sensitive to heat stress and to determine whether genotypic differences in high-temperature tolerance were associated with differences in either cardinal temperatures for pollen germination, the duration of the period of sensitivity to high temperatures, or the extent of the response to high temperature per se. To determine cardinal temperatures, pollen from six genotypes, differing in high-temperature tolerance, was incubated on a gradient plate at temperatures between 10 and 40°C. To identify the critical period of high temperature sensitivity, plants of two genotypes with contrasting high-temperature tolerance were grown under optimum (31 vs. 21°C) and high (38 vs. 21°C) day vs. night temperatures, with selected plants reciprocally transferred between the two temperatures for 5-d periods from just before flag leaf full expansion until 20 d thereafter. Pollen germination, seed set, and grain yield were most sensitive to high temperatures immediately around anthesis. Effects on seed mass were smaller and independent of seed set. Genotypes differed in the magnitude of the response to high temperatures, rather than in the duration of the critical period, and the adverse effect of high temperatures increased with duration of exposure during this critical period. These differences were not associated with cardinal temperatures for pollen germination. These results could assist in identifying selection targets for crop improvement programs.


ABSTRACT This paper addresses the consensus tracking problem for multi-agent linear systems subject to exogenous disturbances generated from heterogeneous exosystems. For the case that the disturbances are generated from linear heterogeneous exosystems, a linear disturbance observer and distributed control law are proposed, and sufficient condition for consensus tracking is established by combining the input-to-state stability and Lyapunov analysis methods. For the case when the disturbances are generated from non-linear heterogeneous exosystems, a non-linear disturbance observer is presented to estimate such disturbance by using the dynamic gain technique; then, a distributed control law is designed, and sufficient condition is also presented for achieving consensus tracking. Two simulation examples are provided to demonstrate the effectiveness of the proposed consensus protocols.


STRUCTURE AND MOBILITY THROUGH CAPILLARY ELECTROPHORESIS By John T. Williams December 2007 Dissertation Supervised by Dr. Mitchell E. Johnson No. of Pages in Text:140 Through the modification of capillary coating procedures electroosmotic flow was controlled without altering the buffer properties. Aqueous buffers of differing ionic strengths were utilized in order to develop a better understanding of the surface properties of nanocrystalline lattices known as quantum dots. Secondary determination of nanocrystal surface properties was determined through the use of a zetasizer. Non-aqueous buffers were utilized in order to determine the effect of the coating on aseparation of hydrophobic, biologically relevant fatty acids. A dynamic capillary surface coat was compared to a successive multiple ionic layer (SMIL) polymeric coat in reguards to resolution and stability. The SMIL coat was further modified to improve resolution in non-aqueous analysis of fatty acids.


Competition is a central part of the evolutionary process, and silicification is no exception: between biomineralized and non-biomineralized organisms, between siliceous and non-siliceous biomineralizing organisms, and between different silicifying groups. Here we discuss evolutionary competition at various scales, and how this has affected biogeochemical cycles of silicon, carbon, and other nutrients. Across geological time we examine how fossils, sediments, and isotopic geochemistry can provide evidence for the emergence and expansion of silica biomineralization in the ocean, and competition between silicifying organisms for silicic acid. Metagenomic data from marine environments can be used to illustrate evolutionary competition between groups of silicifying and non-silicifying marine organisms. Modern ecosystems also provide examples of arms races between silicifiers as predators and prey, and how silicification can be used to provide a competitive advantage for obtaining resources. Through studying the molecular biology of silicifying and non-silicifying species we can relate how they have responded to the competitive interactions that are observed, and how solutions have evolved through convergent evolutionary dynamics.


This paper studies the probability of being hit by unemployment and the amount of unemployment for those who are hit using a subsample of a 5% representative sample of the adult Danish population followed over the 1979-80 period. The probability of being hit and the amount of unemployment for those hit by unemployment are related to the degree of compensation offered by unemployment insurance to lagged unemployment experience and to a number of other background variables. Longitudinal data ideally contain a dating of transitions between labor market states i.e. unemployed employed and nonparticipation. From this dating of transitions it is straightforward to calculate durations of spells in different states. The data in this paper are of a more crude nature as the share of the year spent in unemployment is used called the degree of unemployment instead of the duration of unemployment spells. Technically the degree of unemployment is calculated on a weekly basis as the ratio between benefit hours and potential working hours. The annual degree of unemployment is simply calculated as the average weekly degree during the year. The preliminary results presented apply to a sample of 9275 cases of which 2735 were observations with a positive degree of unemployment. A strong positive history dependence was found both in the probit estimations for the probability of being hit by unemployment and in selectivity-corrected OLS regressions explaining the amount of unemployment for those who are hit. Rather few significant coefficients to the different background variables were found. Consequently much of the individual variation in the amount of unemployment for those who were hit were either explained by true history dependence or related to unmeasured individual factors. A positive effect was found from the benefit-wage ratio on the probability of being hit by unemployment for prime age and older workers. A negative or insignificant effect was found from the benefit-wage ratio on the amount of unemployment. This result came as a surprise in light of the predominantly positive effects reported in the literature. It is argued that this apparent contradiction may be resolved because the standard result applies to duration analyses in single spell samples while the results here apply to the amount of unemployment during a year. Thus policy recommendations based on results from single spell duration analyses should be viewed cautiously.


AIM
This 60-month prospective study aimed to evaluate tooth survival and healing rates after root canal treatment in patients taking bisphosphonates (BPs). Secondary outcomes were complications and clinical variables observed during and after the treatment.

METHODS
Root canal treatment was performed using manual K-file canal instrumentation, a carrier-based filling technique and epoxy resin-based sealer. Teeth without adequate root/crown integrity were restored by trained operators at the tissue level (TL group) to prevent occlusal/mechanical stress and to enable periapical lesion healing without the risk of root fracture. Other teeth were restored with normal occlusal contact (OC group). Healthy patients who had undergone one or more root canal treatments of the same type constituted the control group. The relationships of the following variables to survival and health status were examined (chi-squared test and multivariate analysis, p=0.05): age, gender, smoking habit, tooth location, treatment type, BPs treatment, BPs exposure, initial periapical index (PAI) and occlusal restoration. Survival curves were constructed using Kaplan-Meier analysis, with extraction serving as endpoint.

RESULTS
In total, 65 patients with 109 root canal treated teeth who were taking BPs were included. At 60 months, data from 57 patients (52F, 5M; median-age 65.7±8.6years) who had undergone 96 root canal treatments were analysed (drop-out rate=16.9%). The survival rate was 85% and the success rate was 76%. The control group consisted of 46 patients (21F, 25M; median-age 60.3±7.2years) who had undergone 102 root canal treatments. The survival rate was 88%, with 12 teeth lost during follow-up. The success rate was 73%. In the BPs group, 55 teeth were restored normally (OC group) and 41 teeth were restored at the tissue level (TL group). No difference in the success or survival rate was observed between the BP and control groups (p>0.05). Univariate Kaplan-Meier analysis revealed that only tooth type significantly affected survival status in the BP group. The analysis revealed the clinical relevance of smoking, tooth location and initial PAI on patients' health status (p<0.05).

CONCLUSION
Root canal treatments and post-endodontic restoration with tissue level filling procedures represent a safe approach for severely-damaged teeth in patients receiving bisphosphonates having comparable results to occlusal contact and control group.


gress.P Perhaps the time has come when colonoscopy should be recommended for average-risk individuals at 50 years of age. We now have options to enable screening to be tailored for each individual, which should increase compliance. As compliance is the key to success of any screening program, individual case-finding, rather than population screening, should be the first step. Bell and colleagues remind us how common colorectal cancer is in Australia. We now have techniques to prevent it, and programs involving these should be offered to the community. We need a public education program about diet, as well as a commitment to early diagnosis and prevention and accurate Australian data about the cost-benefit ratio of different screening strategies. If there is little cost-benefit difference between strategies, doctors can at least help patients choose the program that suits them best. The next decade will determine whether or not such measures make a real difference, but only if we decide to implement them.


The regulation of a K+ current activating during oscillatory electrical activity (IK,slow) in an insulin‐releasing β‐cell was studied by applying the perforated patch whole‐cell technique to intact mouse pancreatic islets. The resting whole‐cell conductance in the presence of 10 mm glucose amounted to 1.3 nS, which rose by 50 % during a series of 26 simulated action potentials. Application of the KATP‐channel blocker tolbutamide produced uninterrupted action potential firing and reduced IK,slow by ≈50 %. Increasing glucose from 15 to 30 mm, which likewise converted oscillatory electrical activity into continuous action potential firing, reduced IK,slow by ≈30 % whilst not affecting the resting conductance. Action potential firing may culminate in opening of KATP channels by activation of ATP‐dependent Ca2+ pumping as suggested by the observation that the sarco‐endoplasmic reticulum Ca2+‐ATPase (SERCA) inhibitor thapsigargin (4 μm) inhibited IK,slow by 25 % and abolished bursting electrical activity. We conclude that oscillatory glucose‐induced electrical activity in the β‐cell involves the opening of KATP‐channel activity and that these channels, in addition to constituting the glucose‐regulated K+ conductance, also play a role in the graded response to supra‐threshold glucose concentrations.


Background The healthcare sector was one of the few sectors of the US economy that created new positions in spite of the recent economic downturn. Economic contractions are associated with worsening morbidity and mortality, declining private health insurance coverage, and budgetary pressure on public health programs. This study examines the causes of healthcare employment growth and workforce composition in the US and evaluates the labor market's impact on healthcare spending and health outcomes. Data and Methods Data are collected for fifty states and the District of Columbia from 1999-2009. Labor market and healthcare workforce data are obtained from the Bureau of Labor Statistics. Mortality and health status data are collected from the Center for Disease Control and Prevention's Vital Statistics program and the Behavioral Risk Factor Surveillance System. Healthcare spending data are derived from the Centers for


Based on the application of fuzzy algorithm and neural networks in pattern recognition, the basic theory and application of them in nondestructive testing were analyzed. The experiment of pipeline defect recognition was designed, appropriate parameters were determined, while two methods were applied to effect recognition. According to the comparison and conclusion of experimental result, the validity of two methods was provided which would be a theoretical basis of selection and application with recognition methods.


Abstract A scheme to account for the phytochrome responses of dark grown and green plants is presented. In contrast to some other models (e.g. Smith, 1970; Schafer, 1975) it is proposed that both Pfr and the photoconversions of phytochrome are effectors of phytochrome action and interact to promote the observed responses. Under conditions where Ptot is not strongly wavelength dependent (e.g. with short pulses of light and in plants grown for prolonged periods in the light), responses will be predominantly related to Pfr concentration. Where Ptot is the major wavelength dependent variable (e.g. in the 'high irradiance reaction' of etiolated seedlings) it is proposed that the photoconversion process itself predominates in controlling the ultimate response. Some responses predicted by the scheme are compared with relevant published data.


Abstract This article proposes a systematic analysis of water management and allocation on the scale of a river basin, considering climate impacts and stakeholder networks in the Dongjiang River basin in South China. Specific approaches are integrated to explore various subtopics. Findings indicate a slight increase of precipitation in the basin and strong fluctuations in this century due to climate extremes, which may lead to seasonal or quality-related water shortages. It is highlighted that alternative options for holistic water management are needed in the basin, and participatory water allocation mechanisms and establishment of a basin-wide management framework could be helpful.


The onset threshold of neoclassical tearing modes with finite ion orbit width is studied. The evolution of neoclassical tearing modes including the effect of ion orbit is derived analytically. When ion orbit width is comparable to island width, the effect of ion orbit is significant. It would increase the island width needed to flatten pressure in the island, and reduce the amplitude of ion perturbed bootstrap current. It is found that ion orbit effect tends to increase the onset threshold βθonset for a given seed island. It also would increase the lowest threshold βθ,min and the corresponding marginal island width. It has important implications for the onset of neoclassical tearing modes with comparable ion orbit width and island width in International Thermonuclear Experimental Reactor.


Coping with the stress induced by ESRD patient noncompliance is a time consuming, nonproductive, demoralizing undertaking that is unavoidable. An orderly, non‐confrontational approach encompassing measures to protect mentally incompetent and unaware patients as well as those too sick to comprehend and consent to therapy (dialysis) is provided. Individual practitioners should utilize all available resources including patient relatives and friends, collaborating psychiatrists, and institutional risk‐management officers to assist in devising the best resolution to what may escalate into an onslaught against the renal care team. No single solution is applicable to the myriad variables that may impinge on a specific patient's seemingly apathetic or hateful behavior underlying noncompliance.


The study explores visitor experience while visiting a mountain attraction in the Alpine region of Tirol, Austria, through participant observations, informal conversations, and photography. A grounded theory approach was adopted to uncover the meaning of visitors' overall experience and deduct a possible theory that may contribute to a better understanding of visitor experiences at mountain attractions. The data collected from 600 subjects at the attraction's four stopovers concluded that the visiting experience was a process that involved a blend of events composed of material and human elements. Guest experiences were also practiced on a passive–active continuum, where some of the experiential consumption activities were focused beyond the mountain itself, primarily viewing the landscape and photography. The study affirms the importance of participant observation as a methodological tool to study visitors at a tourist attraction, discusses implications for management, and offers recommendations for enhancing the overall guest experience.


From 1987 to 1994, Zhou Long composed in a manner he declared 'Buddhist'. A work that exemplifies this period—and its aesthetic preoccupations—is the quintet Dhyana. This article investigates that work in close technical detail, exploring how key concepts inherent in the term 'dhyana' are reflected in the music. Most centrally, 'dhyana' implies the oneness of concentration of thought and expansion of consciousness—and concentration and expansion prove to be primary opposites in Zhou Long's compositional technique. Buddhism (especially Chan Buddhism) asserts the inseparability of these opposites. So does the great Tang Dynasty poet Du Fu, in whom Zhou Long has had an abiding interest. And so does Aesthetic Realism, the philosophy of the arts founded by Eli Siegel, which serves as the methodological framework for this article. Central to Aesthetic Realism is Siegel's statement: 'In reality opposites are one, art shows this'.


ABSTRACT The aim of this article is to re-evaluate J. G. Ballard's first novel, The Wind from Nowhere, from the perspective of Timothy Morton's theory of the hyperobject. According to Morton, hyperobjects are entities that, like climate change, challenge the human ability to conceptualise and represent them. Ballard's novel depicts a world overwhelmed by a steadily strengthening wind that itself resembles the footprint of a hyperobject. However, Ballard's strategy for representing the impact of the hyperobject risks turning the novel into a conventional example of disaster-oriented fiction. Confronted by a phenomenon of such apocalyptic severity, his characters have few options. Nonetheless, Ballard's approach problematises Morton's prediction of a future in which humankind cares for the hyperobject, whilst anticipating the emergence of a new form of 'weird' realism perhaps better able to render life in the time of hyperobjects.


Ring reactions of the cornea have been given a new nomenclature based upon their mechanism of formation. The term immune corneal ring includes all types and distinguishes ring reactions from the general term, "anaphylactic" keratitis. The systemic immune ring, arising slowly from serum antibody ami cells at the limbus, is distinguished from the local immune ring, which rapidly develops at the "target site" of injection. The former type develops from a single corneal injection, whereas the latter is dependent upon at least one reinjection of antigen and appears to begin independently of systemic immunity. A local tissue antibody of as yet undetermined origin is postulated to stimulate the formation of local immune rings. The origin of the cellular component of local rings is still undecided. Systemic immune rings which are another manifestation of the Wessely phenomenon and which normally develop about 2 weeks after sensitization tuill usually develop within 6 or 7 days in animals previously sensitized systemically; the accelerated reaction can occur as early as 1 day after challenge. Reactions that develop in 1 or 2 days after intracorneal challenge can occur in the absence of demonstrable corneal vascularization. A delayed hypersensitivity component is postulated to account for the tissue damage observed in some of the corneas. The importance of the breed of rabbit used in this type of study is emphasized.


Equations that describe the behaviour of a queue in a storing system of a solid stochastic queueing net are constructed. The correctness of the proposed model is demonstrated. An approach allowing to calculate directly generating functions of phase characteristics of the system is offered. The construction of systems of differential equations for the probabilities of states is traditional in the problems of queueing systems (QS). In this case the object of research is not the process describing the behaviour of a system but the probability characteristics of this process. This paper gives another approach based upon the construction of stochastic differential equations, that describe the phase variable itself. This allows us to use a powerful mathematical technique. In addition, equations for generating functions, for example, are obtained as natural consequences of well-known theorems of the theory of stochastic differential equations. In some cases they can be solved. Stochastic networks of QS are chosen as the model object [1]. Consider a stochastic queueing net comprising storing systems (SS) of infinite capacity and mobile systems (MS) of capacity n. We assume that a flow of passengers, described by Poisson's process μ(ί) with intensity λ, enters every SS. The flow of MS, entering SS, can also be described by Poisson's process v(t) with intensity λ. The processes μ(ί) and v(t) are independent. We assume that loading and unloading of MS in SS happens instantly. 1. THE FIRST SS First, let us consider the behaviour of a queue in the first SS. Let K,(t) be the length of the queue of passengers in SSi, at the moment of time t, t\ is the moment of arrival of Μ Si inASi. Then άκ(ί) = άμ(ί) min(/c(*), n) di>(<) + Xdt φ min(Ac(<), n) dt, /c(0) = χ . ( ) Here μ(ί) and v(i) are centered Poisson's processes. It can be easily seen that the coefficients of the equation (1) are linearly bounded and satisfy Lipshitz' conditions, so that there exists a unique right-continuous solution without discontinuities of the second kind (see [2], p.429).

Machine learning techniques enable systems to learn Important representations from input Image data. Convolutional neural networks (CNNs) are a specific implementation of machine learning techniques and are able to create expressive representations from the input image. Hence CNNs are well suited for image processing operations such as classification, clustering, and object detection, etc. The creation of a new effectual deep CNN model involves an extensive training phase. This requires very large datasets, huge computation environments, and longer execution time. Several established deep CNNs are readily available. These networks are pre-trained on massive databases of images. VGG, ResNet, and InceptionResNetVZ are the leading pre-trained CNN models currently being used in numerous image-processing studies. Possibly we can transfer knowledge learned from such models in order to address challenges in different domains. This can be achieved by repurposing a deep CNN model as a feature generator to produce effective features for content based information retrieval applications. This research work proposes a technique for recognizing fish using deep convolutional neural networks such as ResNet-50, InceptionResNetVZ, and VGG16 that have been pre-trained using transfer learning.


It is necessary and possible that dialogue, communication and understanding between different cultures are realized by cultural exchange in the course of creating the pluralist system of world culture. However, in the course of cultural exchange, we should pay much attention to psychological, theoretical and ethical issues on dialogue, communication and understanding between different cultures. Psychological issue means that both sides of dialogue should have good faith to carry on cultural exchange with acceptable discourse of both sides when there are differences in the course of the exchange. It will deal with issues of psychological conflict and eliminate confident deficit in cultural exchange. Theoretical issue means that we should do research on "what" and "why" of thinking style under different historical and cultural conditions in cultural exchange. It will deal with conflict issues of generally acknowledged truth and eliminate understanding deficit. Ethical issue means that there is a bottom line of moral will freedom and ethics in cultural exchange in order to maintain the diversity of global culture and the existence of different cultures. It can deal with conflict of communication ways in the exchange and eliminate confident deficit as well. In the meantime, media play a very important part in the course of paying much attention to communications of psychology,theory and ethics in cultural exchange.


This study was conducted in order to present more information and evidence to authorities to make them capable of making better decisions. Survey was done in batch conditions on wastewater of Binalood paint industries using different amount of wood ash as adsorbent and in variable pH from acidic to alkaline and different contact times. Cadmium measurement in samples was done with atomic absorption equipment and test methods were adapted from standard methods for the examination of water and wastewater. This investigation showed that wood ash has high effectiveness in cadmium removal and this effectiveness raises with the increase of the amount of adsorbent substance to 100 g L-1 wastewater, where adsorption rate reaches 97-98% in acidic, neutral and alkaline pH. Data concerning adsorption isotherms indicates that, adsorption process follows Freundlich model. Concerning the results of this research and other investigations, the use of fly ash and wood ash is recommended as a low cost and available material to remove cadmium from municipal and industrial wastewater.


ABSTRACT By growth, in size and complexity (i.e., changing from more probable to less probable states), plants and animals appear to defy the second law of thermodynamics. The usual explanation describes the input of nutrient and sunlight energy into open thermodynamic systems. However, energy input alone does not address the ability to organize and create complex structures or explain life cycles — in particular, growth, regulation and dying in the presence of adequate nutrients. Understanding the roles of macromolecules such as DNA, with their apparent information-processing capability, affords opportunity to understand biological order.


This study intends to investigate qualitatively the impressions and interpretations of students of licentiateship in Physical Education about the required internships that they experienced during the course. By reading the reports produced in these activities, we aim to gather the contributions they have provided to these students. In this sense, we ascertain the possible contributions of internship experiences gained by the students of Licentiateship in Physical Education at USP, developed in the disciplines Teaching Methodology of Physical Education I and II of School of Education of USP. As a method of scientific research, we chose the content analysis, based on recommendations of Lankshear and Knobel (1998), applied in the reports prepared by undergraduates. The results reveal that internship, even when it does not offer an idealized learning situation to the intern, which would be equivalent to a school where everything worked with teachers that are fully committed to work Physical Education seriously, serves as an important motivator reflection and critical analysis to the future teacher.


Nationwide, a surge in students who are under-prepared for collegiate mathematics has left institutions struggling to meet the needs of these learners. Many schools have moved to online or hybrid instructional models for developmental mathematics. These models work very well for many students, but not at all for others. At Clemson University, all STEM majors who are not yet calculus ready take precalculus under a self-paced hybrid course model that includes an asynchronous online component using ALEKS R © (Assessment and LEarning in Knowledge Spaces) and a face-to-face component with targeted direct instruction in small groups. The ALEKS R © software allows students to master objectives at their own pace following an individualized learning path. One lens for understanding why some students struggle in hybrid courses is to observe how a student approaches a task. The Kolbe ATM Index measures an individual's conation, his/her method of operation when given the flexibility to choose how to approach a task. In the hybrid precalculus course at Clemson University, each student works independently on the selfpaced component and can be assumed to follow his/her natural instincts for task completion. The objective of this study is to use a third-party assessment of conation to predict at the start of the semester which students will struggle in the hybrid model course and, ultimately, to offer recommendations on how to help these students complete such courses. This study focuses on the correlation between Kolbe ATM results and student performance in hybrid precalculus to determine if certain conative categories are particularly well-suited or poorly-suited to this course model. We report preliminary data from a Fall 2016 pilot study and discuss next steps to predict which students are "at risk" on the basis of Kolbe ATM results. Course Structure of Precalculus Calculus is a common prerequisite for introductory courses in science, technology, engineering, and mathematics (STEM) disciplines. Students who are not yet ready to take calculus must take precalculus in order to start the path towards a degree in a STEM discipline. The precalculus course at Clemson University is a pass/fail hybrid course in which students have a face-to-face component as well as an online self-paced component using ALEKS R © (Assessment and LEarning in Knowledge Spaces). Self-paced component: ALEKS R © ALEKS R © is an online assessment and learning system that individualizes learning paths using a proprietary web of conditional probabilities for topic acquisition1. ALEKS R © includes content information, practice problems, and integrated learning resources1. Each student takes an Initial Knowledge Check (IKC) in order for ALEKS R © to determine what the student already knows and where to start the student's individual path. ALEKS R © can be configured in many ways to meet an institution's specific instructional design needs. At Clemson University the course content, ranging from adding fractions to conic sections, is segmented into 12 sequential objectives. There are no fixed due dates for objective completion; students move to the next objective when they have reached a minimum mastery level (80%-95% depending on the objective). The course is graded pass/fail and students must complete all 12 objectives and pass an exit exam in order to pass the course. Students are given a timeline of target dates for objective completion. The intention is to provide students with a gauge of their progress in the course: ahead, on schedule, or behind schedule (Figure 1). Figure 1: Weekly timeline with targets for completion of objectives Conation and Kolbe A Although student success in first-year courses has been studied extensively through many lenses2,3,4, there have been few studies focusing specifically on hybrid models. In a two-institution study, Clayton et al. found that high motivation correlated with student preference for hybrid-model courses5. Manuelito determined that self-regulated behaviors correlated with student success in hybrid science courses6. There is therefore some evidence that both behavior and motivation are factors in student success in hybrid courses. We focus more narrowly on conation, which is closely linked to both motivation and behavior. Following on the work of Huitt and Tallon7,8, we consider three aspects of the mind: cognition, affection, and conation. Conation is exhibited when an individual applies cognition (learned information) and affection (motivation/value) to strive at a task utilizing instinctive actions9,10. Put another way, conation is an individual's self-determined behavior9,10. In this study, we utilized a commercially available tool, Kolbe ATM, to measure individuals' conation. Developed by Kathy Kolbe, the Kolbe ATM assessment has been used most often in business settings for professional development involving teamwork9,11,12. Validation studies have shown no indication of gender, racial, or ethnic bias, and have established test-retest reliability11,12. The Kolbe A is a 36 question survey that provides four numerical scores, each representing an Action Mode R © (Fact Finder, Follow Through, Quick Start, and Implentator)9,11. Based on the combination of scores, Kolbe ATM determines the dominant mode(s) of operation for an individual. Kolbe Corporation has identified 17 distinct action combinations, or Natural Advantages , describing how individuals navigate through a problem or process in the absence of external restrictions11. Each Natural Advantage is given an archetypal descriptor such as Researcher, System Analyst, Pioneer, or Entrepreneur. These are not job titles, but rather terms intended to evoke a mental image of the traits embodied within the category. We hypothesize that natural work patterns strongly affect an individual's performance in selfpaced courses because external limitations such as time restrictions or number of attempts are not in effect. Since the hybrid course is self-paced, we expect that students' natural tendencies to action will surface in their work patterns over the course of the semester. Our pilot study poses the specific research question: Does Kolbe A TM Natural Advantage TM category predict work pattern and course performance in the self-paced component of a hybrid precalculus course?


Comparison of surgical approaches to bezoar-induced acute mechanical intestinal obstruction Purpose: To evaluate the patients who were operated on for acute mechanical intestinal obstruction secondary to intestinal bezoars. Materials and Methods: Eighteen patients who were operated on due to intestinal bezoars, were investigated according to their age, gender, preoperative diagnosis, type of operation, operation time and postoperative complications. Results: Ten of the 18 patients underwent segmental resection of the small intestine, while bezoar extraction and enterotomy was per - formed in eight patients. No difference was detected among inves - tigated parameters between the two groups. Conclusion: Despite a variety of surgical, pharmacological, and endoscopic treatment modalities have been defined for intestinal bezoars, the standard model of treatment is still controversial


In India, oral squamous cell carcinoma accounts for 90%–95% of oral malignancies. The WHO classifies spindle cell carcinoma (SpCC) under malignant epithelial tumors of squamous cell carcinoma (SCC) and is a rare entity accounting for only 1% of SCCs. It is an aggressive biphasic neoplasm exhibiting high mortality rate owing to increased metastasis and recurrence which signifies the need for recognition and treatment of this perplexed tumor. We present a case of maxillary SpCC where histopathological evaluation alone was indecisive, requiring immunohistochemistry for confirmation of the diagnosis.


Database Programming II is one of the subject taught in STIKOM SURABAYA to achieve international certification. This subject concerns on Procedural Language/Structure Query Language (PL/SQL). In which it is one part of Oracle's international certification. Question types in Database Programming II is similar to the question type for Oracle's certification, however, its exam implementation is quite different between both. Although Database Programming II exam has been conducted online on the laboratory, it is still found some weaknesses of its system. Referring to the experiments that have been done, it can be concluded that the new system could accommodate some questions in form of image or table which can overcome the weaknesses. The new system could be apply as certification exam simulation for student of STIKOM SURABAYA which supports them in preparing them to join Oracle certification, especially PL/SQL. Indeed, this system also could help the Database Programming II lecturer in evaluating Database Programming II effectively.

Glioblastoma (GBM) is the most common and lethal primary intracranial tumor. The recent standard-of-care treatment consisting of surgery, followed by radiotherapy and temozolomide, just prolongs the median survival period of GBM patients to 14.6 months. What impedes the survival is due to the extensive heterogeneity among GBM patients at both the cellular and the molecular levels. In our study, we focused on the precision medicine strategy targeting NOTCH signaling. According to recent Phase I/II clinical trial results, only a few GBM patients showed satisfactory response to GSIs. However, little is known regarding how to distinguish GSI-responsive patients. Here, we illustrated that it required (1) high NOTCH activity, (2) wild-type p53 and elevated P53 activity, (3) increased MAPK activity, and (4) decreased PI3K/AKT activity for GBM to respond to GSIs. In our study, we tested a series of patient-derived primary glioma stem cells (GSCs) to two GSIs (RO4929097 and BMS-708163). GSI-sensitive lines were identified and GSI compounds impaired cell viability and sphere formation ability in these cell lines. GSIs also induced cell death of the sensitive GSCs. To find out the signature of the GSI-sensitive GSCs, we did enrichment and correlation analyses against RNA sequencing, RPPA, and methylation data of the GSI-sensitive and resistant GBM lines. We found that GSI-sensitive GSCs harbored significantly elevated Notch activity (high NOTCH1 and NICD1 expression, and low Notch1 methylation). Interestingly, GSI-responsive cells also possessed increased P53 activity (increased expression of P53 targets-P21, BAX and TIGAR), high wild-type p53 frequencies, increased MAPK activity (elevated p-Erk1/2-Thr202/Tyr204 expression), and decreased PI3K/AKT activity (high PTEN expression and low p-AKT-Thr308, RAPTOR, p-4E-BP1-Ser65 expression) (P Citation Format: Chen Zhang, Martinez-Ledesma Juan, Jie Ding, Feng Gao, Shaofang Wu, Xiaolong Li, Erik Philip Sulman, Dimpy Koul, WK Alfred Yung.

Celebrity endorsements, an advertising strategy, is used in a variety of industries today, counting fashion, cosmetics, sports, food, and a myriad of others. With the popularity of social media platforms and the increased penetration of viewership of digital cable television, it is indeed a growing mascot for brands today. In an age where people spend substantially long hours on social media and around technology, there's no dilemma for the fact that celebrities and influencers have a constant effect on a consumer's decision-making. From solely depending upon the products' characteristics as the key point of selling to making use of an influencer's brand value in the dynamic market, today it is most importantly about how a company is using its resources to educate consumers about the assistance, quality, and value of their offering that in turn, helps the consumers to make their buying decisions smoothly.

Abstract. Supriyomo, Soviana S, Novianto D, Musyaffa MF, Tan S, Hadi UK. 2022. Morphological characteristic of malaria vector Anopheles aconitus (Family: Culicidae) revealed by advanced light and scanning electron microscope. Biodiversitas 23: 3546-3552. Anopheles aconitus (An. aconitus) is one of the primary vectors for malaria in several areas in Indonesia, especially in Java Island. Scanning electron microscope (SEM) is a powerful tool that can differentiate Anopheles spp. Morphology that is difficult to identify by using a light microscope only. The adult of An. aconitus used in this study have been reared in the laboratory. This research is conducted to better understand the Anopheles aconitus' external morphology, such as the head, proboscis, wings, thorax and legs, using advanced light and SEM. Results from an advanced light microscope showed that An. aconitus has palpus with the same length as proboscis with one narrow basal end and two broad distal ends; meanwhile, the apical half of proboscis is pale. Anopheles aconitus has wings with four pale spots on the costa side. Legs are uniformly dark with only very narrow, rather faint pale bands at the joining of segments. Using SEM, we found several types of sensilla trichodea: short-sharp tipped, short-blunt tipped, and long-shaped tipped in antenna, apical proboscis, maxillary palps, abdomen, and legs. Antenna is also covered with microtrichia and sensilla. This research is important for basic necessity in fully understanding and determining of mosquito bionomic due to the development of effective and efficient mosquito vector control strategies.


The presence of resonance frequency offsets often causes artifacts in images acquired with true fast imaging with steady‐state precession (true‐FISP). One source of resonance offsets is a suboptimal setting of the synthesizer frequency. The goal of this work was to demonstrate that shifting the synthesizer frequency could minimize the off‐resonance related image artifacts in true‐FISP. A simple scouting method was developed to estimate the optimal synthesizer frequency for the volume of interest (VOI). To improve fat suppression, a similar scouting method was also developed to determine the optimal frequency offset for the fat saturation pulse. Coronary artery imaging was performed in healthy subjects using a 3D true‐FISP sequence to validate the effectiveness of the frequency corrections. Substantial reduction in image artifacts and improvement in fat suppression were observed by using the water and fat frequencies estimated by the scouting scans. Frequency shifting is a useful and practical method for improving coronary artery imaging using true‐FISP. Magn Reson Med 49:803–809, 2003. © 2003 Wiley‐Liss, Inc.


Ultra-fine SAC305 solder is widely used as lead-free interconnection in advanced packaging because of its advantages such as good joint strength, thermo-mechanical fatigue behavior and creep resistance. Stencil printing remains the technology of choice for assembling because of its ease of process control, flexibility of usage, wider process window, and economic usage. Advanced package involves integration of different components, copper (Cu) pillar, flip-chip devices, and chips in one package to achieve multiple functions in one system. The need to accommodate ever increasing demands for reduced footprints requires constant inventions of flip chips with Cu pillar diameter of $\mathbf{55}\boldsymbol{\mu} \mathbf{m}$ and smaller. Many mobile communications consist of 6 or more flip chips in a single package. Conventional flip-chip attach uses flux and Cu pillar solder cap for interconnect formation, it is a challenge to print solder paste of fine geometries below $\mathbf{70}\boldsymbol{\mu} \mathbf{m}$. Heraeus's solder paste makes use of ultra-fine spherical shaped solder powder (T7 particles size) to create strong metal coalescence for bonding during reflow process of Cu pillars onto substrates. Reduction in flip-chip Cu pillar diameter to $\mathbf{55}\boldsymbol{\mu} \mathbf{m}$ requires further reduction in stencil opening to $\mathbf{55}\boldsymbol{\mu} \mathbf{m}$, thus limiting the usage of T7 paste. Present study reports stencil printing application of new version of T7 solder paste with reformulated flux system. The application evaluations using $\mathbf{55}\boldsymbol{\mu} \mathbf{m}$ stencil opening (SO) revealed good results by successfully printing $\mathbf{35}\boldsymbol{\mu} \mathbf{m}$ line spacing (LS) without defects such as bridging, missing & inconsistent dots. It also achieved average paste release volume of ~30% up to 12hours of continues printing.


Conservation research has a main role to play during the decision-making process of restoration – how an object should look, what should be removed, what should be clearly exposed, and how to connect history and conservation with the aesthetic effects expected by the owner. In many situations we do not have enough historic material to fully establish this. In this article we would like to describe the process and steps taken during microchemistry research to identify the original technology used in the painting and gilding layers of a terracotta sculpture, dated to the late nineteenth century.


Objective: To clarify the treatment results of three-dimensional (3D) image-guided brachytherapy (IGBT) for cancer of the cervix uteri in Hong Kong. Methods: Between January 2014 and June 2016, 52 patients underwent computed tomography (CT)-based 3D IGBT, in which three patients had interstitial needles inserted. Contouring was done with dose volume parameters recorded, as recommended by the GEC-ESTRO guidelines. Recorded parameters included HRCTV D90 mean dose (dose delivered to 90% of the high-risk clinical target volume), HRCTV V100 (percentage of HRCTV receiving 100% of the prescribed dose), and D2cc (minimum dose in the most exposed 2 cm 3 volume) of rectum, sigmoid colon, and bladder. One-way analysis of variance with Bonferroni's multiple comparison post-hoc tests for normally distributed data or Dunn's multiple comparisons test were used to assess any statistically significant differences. Results: The HRCTV D90 mean doses in 2014, 2015, and 2016 were 75.1 Gy, 77.8 Gy and 82.1 Gy, respectively. The corresponding HRCTV V100 values were 88.7%, 91.6%, and 94.4%, respectively. The HRCTV D90 value in 2016 was found to be significantly higher than that in 2014. The D2cc value of sigmoid colon in 2016 was significantly lower than that in 2014 or 2015. The D2cc value of bladder in 2016 was significantly higher than that in 2015 but still within acceptable limits. None of the patients developed grade 3 to 4 acute radiation toxicities. There was one patient with persistent disease in the cervix after radiotherapy, three patients with distant failure, and one patient with both local and distant failure. Conclusion: The CT-based 3D IGBT treatment for cancer of the cervix uteri with interstitial needle insertion is feasible in the local setting. There is potential to give higher dosages to the HRCTV by the 3D IGBT technique, while the doses to organs at risk can still be limited to acceptable levels.


With the development of modern science and technology and the wide application of new technologies in the field of education, the reading environment and reading style of primary and secondary school students have changed. "Internet +" reading has aroused people's extensive attention, and the reading effect and its influencing factors in the new environment are worth exploring. This study aims to explore the influencing factors of the "Internet +" reading effect of primary and secondary school students. This study used a linear regression method to answer four hypotheses. The results show that reading interest is significantly positively correlated with the reading performance of primary and secondary school students. In addition, reading habits, reading motivation, reading self-efficacy and reading effects were significantly positively correlated. Through the discussion of the influencing factors of the "Internet +" reading effect of primary and middle school students, it provides a useful reference for the reading education in primary and secondary schools under the new situation in the future.


The notion of the univariate divided differences is generalized to the multivariate case. This generalization is based on a pointwise evaluation of a certain multivariate function. Several properties of the defined multivariate divided difference functional are derived, and a link with the multivariate simplex splines is established. This gives a new generalization of the so-called truncated power function, which is different from the one given in [Multivariate Approximation Theory, Birkhauser Basel, Switzerland, 1979, pp. 69–82] and [SIAM J. Numer. Anal., 17 (1980), pp. 179–191].

Methods CT findings in 31 cases with traumatic atelectasis of complete clinical data were retrospectively analyzed. Results Of 31 cases,acute traumatic atelectasis was found in 12 cases (n=12), and delayed Atelectasis was found in 19 cases (n=19). Conclusion there were a lot of reasons which led to traumatic Atelectasis. In addition to bronchioles obstruction,it was related to contusion of lung,laceration of lung, delayed hemothorax,pneumothorax or together with pleural effusion.CT is the effective examination for traumatic atelectasis and for guiding the clinical management.


One of the major problems in the modern fishery industry is the bycatch of non-target species and undersized fish. To reduce the damage on species, populations and ecosystems caused by bycatch, research and development of alternative gear during the last decade has focused on size and species selectiveness. Since the end of the 1990s, the increasing grey seal population within the Baltic Sea has lead to growing problems within the small scale fishery for cod. It is thereby of interest to develop seal proof gears with the ability to prevent seals from reaching the catch. A gear that could be of interest in the cod fishery in the future is baited pots. Pots have potential as seal proof gear and are known to have high size and species selectiveness. The purpose of this study is to evaluate pots within the Baltic cod fishery. A bait selection test will be conducted using herring, squid, shrimp and empty pots. Discard rate and soaktime is analysed and a comparison with gillnets is conducted. The results showed herring as the most efficient bait in comparison to squid and non-baited pots. When herring was compared to shrimp no difference was found between the two baits. Discard rate was 47.2 % within the study, which may be reduced by implementation of a selection panel in the pot. To get the best fishing results, three sets of links containing eight pots each should be used and each set should be collected from catch every third day. Even though pots in the study showed less catchability then gillnets, the gear still is in its very earliest stages and has a bright future ahead of it, based on several beneficial characteristics as high selectiveness towards the target species, keeping its catch alive inside the gear and ability to fish during hard weather conditions.


Purified orally bioavailable female sex hormones isolated from pregnant mare urine or synthetically derived from plant materials and primarily conjugated as sulfate esters. Estrogen binds to and activates specific nuclear receptors, which, in turn, bind to estrogen response elements (EREs) in target genes, resulting in histone acetylation, alteration of chromatin conformation, and initiation of transcription.

Baijiahai-Wucaiwan area in eastern Junggar basin is characterized by multi-source and multi-stage hydrocarbon accumulations.This paper analyzes the essential conditions for forming dynamic system of hydrocarbon accumulation in this studied area in terms of the geologic structural setting.Through comprehen-sive analyses of geothermal field,pressure field,fluid potential and fluid chemical property,it discusses the relations among these factors and generation and expulsion of hydrocarbon,hydrocarbon migration and accumu-lation as well as time-space geologic process for reestablishing hydrocarbon accumulation.Based on study of the static and dynamic factors,a program for classification of the fluid dynamic system of hydrocarbon accu-mulation in Baijiahai-Wucaiwan area is proposed,that is,the system can be divided into an allogenic open system in Baijiahai salient and a self-source and semi-enclosed system in Wucaiwan sag,Such a classification offers new thoughts for further exploration in this area.In Baijiahai salient it is dominated by searching for multi-orientation oil/gas-filled or secondary reservoirs,while in Wucaiwan sag by finding self-source and self-reserved pools.


In this study, analysis on the oxidation behavior was conducted by a series of high-temperature oxidation tests at both 800 o C, 900 o C and 1000 in the air with sintered STS 316L. The weight gain of each oxidized specimen was measured, the oxidized surface morphologies and composition of oxidation layer were analyzed with Scanning Electron Microscope-Energy Dispersive x-ray Spectroscopy (SEM-EDS), finally, the phase change and composition of the oxidized specimen were shown by X-Ray Diffraction (XRD). As a result, the weight gain increased sharply at 1000 o C when oxidation test was conducted for 210 hours. Also, a plentiful of pores were observed in the surface oxidation lay-ers at 900 o C for 210 hours. In addition, the following conclusions on oxidation behavior of sintered STS 316L can be obtained: Cr 2 O 3 can be formed on pores by influxing oxygen through open-pores, (Fe 0.6 Cr 0.4 ) 2 O 3 can be generated on the inner oxidation layer, and Fe 2 O 3 was on the outer oxidation layer. Also, NiFe 2 O 4 could be precipitated if the oxidation time was kept longer.

The utility model discloses a recycling device for waste heat from a fabric forming machine. The recycling device for the waste heat from the fabric forming machine comprises a drying oven and an air outlet pipe which is communicated with the drying oven. The recycling device for the waste heat from the fabric forming machine also comprises a heat exchange tank, an air return fan, an air return pipe and a secondary air outlet pipe. A radiator is arranged in the heat exchange tank; both ends of the radiator are respectively communicated with the air outlet pipe and the secondary air outlet pipe; the air return fan and the air return pipe are located on the same side face of the heat exchange tank and are respectively communicated with the heat exchange tank; the air return pipe is also communicated with the drying oven; and insulating layers are respectively coated outside the heat exchange tank, the air outlet pipe and the air return pipe. According to the recycling device for the waste heat from the fabric forming machine, heat exchange is performed between high-temperature waste gas generated in the drying oven and dry cold air blown into the heat exchange tank through the air return fan through the radiator in the heat exchange tank; the high-temperature waste gas enters the secondary air outlet pipe for follow-up treatment after the heat of the high-temperature waste gas is emitted; the dry cold air enters the air return pipe under the action of air pressure after obtaining enough heat in the heat exchange tank, and enters the interior of the drying oven along the air return pipe.


By deploying computing, storage, and bandwidth resources at the user side, vehicular edge computing (VEC) provides low-delay services for vehicle users. However, due to the limited resources of edge servers, how to efficiently meet the Quality-of-Service (QoS) requirements of multiple tasks and save the total energy consumption in a dynamic environment is an important issue in VEC. In this article, we first propose an energy consumption and QoS-aware co-offloading model. Unlike most previous studies, our goal is to minimize the total energy consumption while guaranteeing the QoS constraints of tasks, thus avoiding the overallocation of resources and high energy consumption caused by the one-sided pursuit of delay minimization. Then, without the requirements for domain experts, we propose Bayesian optimization-based computation offloading (BOCO) method to find the optimal offloading decision. To the best of our knowledge, this work is the first to apply Bayesian optimization to computation offloading in VEC. Furthermore, we conduct a series of experiments and comparisons with other offloading methods to analyze the effectiveness and performance of the proposed algorithm. Experimental results verify that our proposed BOCO outperforms counterparts.


VACLAV MUSIL, MAREK SADILEK, ROBERT CEP, SARKA MALOTOVA VSB Technical University of Ostrava, Faculty of Mechanical Engineering, Ostrava, Czech Republic DOI: 10.17973/MMSJ.2018_06_201763 e-mail: firstname.lastname@example.com Unconventional machining methods, or also progressive machining methods, such as laser cutting, waterjet cutting, ultrasound machining, etc. are undergoing a very rapid development. Laser cutting machines often evaluate even 80 parameters in real time. Their advantage is the significantly higher productivity. Many values are defined by the machine manufacturer and can not be changed for a given laser. For custom laser cutting there are 2 essential parameters, adjustable depending on the process gas employed. The aim of this article is to find the setting that will reduce the consumption of process media while maintaining or improving the quality of the machined surface.


The problem of the automation of transport systems investigations is considered.

This approach is illustrated in terms of development of automatic system of investigations of railway rolling stock.


To study the relationship between the burning rate and the characteristic value of combustion wave,the combustion wave structure of double-base propellant with low burning rate and low flame temperature were obtained by using the technology of imbedded minimized thermal couples into propellant,and the experimental data were calculated and the characteristic value of combustion wave,the surface temperature,the dark zone thickness,the temperature grades of condensed phase and gas phase fizz zone,were obtained.Burning rate of propellants without catalysts increases with the surface temperature increasing,and the surface temperature of propellants with catalysts is higher than that of propellants without catalysts.Flame temperature enhances with increase in pressure,and there is not necessary relationship between flame temperature and burning rate.Results show:the relationship between the burning rate of the said double-base propellant with low burning rate and low flame temperature and the characteristic value of combustion wave is rather complex,and there are linear and non-linear relationships when combustion performance changes.The reason is that combustion wave structure is changed with catalysts.


The use of unlicensed frequency bands has gathered much interest recently to meet the bandwidth requirements of beyond 5G networks. However, the frequency overlap between radio technologies such as LTE-U, Wi-Fi, and ZigBee can cause severe interference and hamper communication reliability. This inter-technology interference is particularly unfavorable for IoT devices operating on the ZigBee network that shares the same unlicensed band with Wi-Fi capable of transmitting at 10–100 times higher power. Our real-time experiments study this transmission power asymmetry and examine the interference patterns between IEEE 802.11 Wi-Fi and IEEE 802.15.4 ZigBee networks at bit-level granularity; the simulations were performed on the Zolertia Z1 platform. This paper evaluates the system performance under different settings and the scalability of a real-world ZigBee network. We observed that Wi-Fi activity can trigger a nearby ZigBee device to back off for a certain time and starve under certain conditions. We also demonstrate that most of the link disconnectivity and packet loss are mainly due to channel access failure rather than errors in data transmission. The observations illustrated in this work would help researchers to propose efficient solutions for heterogeneous IoT networks and design modern data communication protocols for ZigBee devices that are likely to operate in an environment that coexists with dense Wi-Fi deployment.


The writer considers the subfamily Perlinae to include the Perlidae which have the male subanal lobes little modified (not produced into sharp hooks), which have the tenth tergite cleft and the posterior angles of the cleft thickened and produced into forward-pointing processes or "genital hooks," and which have three normal ocelli (Ricker, 1943). A systematic review of the subfamily is badly needed, but since the species are mostly Old World ones, it will probably be done by a student having good access to such material. However, the Old World species currently included in Perla , having rather large, simple genital hooks, seem sufficiently different from all American species that the latter should not be included in the type genus. Another fairly distinct group is Neophasganophora Lestage ( Phasganophora Klapalek), which has a single species in America. There is a considerable number of species, including the five discussed in this paper, in which the genital hooks have a large callus or shield ("Schwiele") on the inner side. Whether all such species should be included in one genus is debatable; if so, the genus would include most or all of the species ascribed by Klapalek (1923) to Paragnetina, Tylopyge, Togoperla and Banksiella . Whether or not one inclusive genus of this extent should be recognized, the five American species seem to be best contained in a single genus. The genital hooks of all are rather short, not cleft at the tip, and have the callus well developed. They all have a median backward-pointing lobe on the male eighth tergite, though this is quite small in kansensis . In the female, all five species have the subgenital plate slightly to moderately produced, and bearing a small median notch or excavation. Variety appears in the presence or absence of a posterior extension of the male fifth tergite, excavated or bifid at the tip: this is present in media, immarginata and fumosa , but absent in kansensis and fattigi . The type species of Paragnetina also has such a process. At a subgeneric level a separation of the species lacking it from those which have it would probably be useful, but the matter should be left for a comprehensive revision of the group. Currently our five species are involved in an annoying confusion of specific and generic nomenclature.


1.1. Background: Spine pain is widespread due to degenerative disc disease and facet arthropathy. Most patients improve with supportive conservative care measures, including non-steroidal anti-inflammatories, physical therapy, short episodes of rest, and activity modification. Medical and interventional pain management is reserved for those patients who do not improve within 4 to 6 weeks of standard spine care managed within the primary care setting, after which patients are typically referred to a specialist. Genetic conditions are rarely considered early in the differential diagnosis and may be easily missed in non-responsive patients. 1.2. Methods: We briefly de-scribe two illustrative cases of patients with a history of chronic musculoskeletal and spinal pain, whose delayed diagnosis led to improper utilization of medical resources until they were diagnosed correctly and targeted personalized care for their painful syndromes could be instituted.


The invention relates to an automatic communication management. In particular it relates to an automated closing communication in circumstances of establishment of untimely communication, especially from mobile devices.

Based on the basic generation model for the independent component analysis(ICA) and the fixed-point FastICA algorithm using negentropy,three observed signals containing maternal electrocardiogram(MECG) and fetal electrocardiogram(FECG) components obtained from abdomen of a pregnant woman are successfully separated by using the FastICA algorithm with progressive orthogonalization,and the FECG is extracted.By invoking the wavelet de-noising program in Matlab,the extracted FECG is decomposed to 8 levels with db2 wavelet to obtain the default soft threshold for de-noising.The results show that the FastICA algorithm with progressive orthogonalization performed fast convergence.The three source components were extracted with only seven,three,and two iterations,respectively.The noise in the extracted FECG can be eliminated using wavelet de-noising.

Anomaly detection is a concept widely applied to numerous domains. Several techniques of anomaly detection have been developed over the years, in practice as well as research. The application of this concept has extended to diverse areas, from network intrusion detection to novelty detection in robot behavior. In the business world, the application of these techniques to fraud detection is of a special interest, driven by the great losses companies endure because of such fraudulent activities. This paper describes classification-based and clustering-based anomaly detection techniques and their applications, more specifically the application to the problem of certain fraudulent activities. As an illustration, the paper applies K-Means, a clustering-based algorithm, to a refund transactions dataset from a telecommunication company, with the intent of identifying fraudulent refunds.

With the rapid development of social economic and the growing power demand, it brings the phenomenon that the capacity of power network is expanding gradually and the load feature has changed very much. The peak-valley difference is becoming larger and larger with an annual increasing trend and the problem of peak load shifting has been increasingly apparent. It can solve the problem by charging during valley period and discharging during peak period using of the storage technology of flow battery (FB). It helps to make the peak load shift to the valley, so that it can improve the load feature. Based the application of peak load shifting, this paper presents a methodology to optimal the capacity of flow battery, it builds the optimization model to determine the sizing capacity of flow battery while the objective function of this model is to maximize the benefits the power system. It's based on the example network's load feature and the security of the system network and charge-discharge characteristics of flow battery as its constraints. While the capacity of flow battery has been determined, an operating strategy of flow battery to dispatch power has been presented. The result is significant to demonstrate that the application of FB to implement the peak load shifting has great advantages.


In The Moment of Complexity: Emerging Network CultureMa~k c. Taylor writes, The contrast between grids and networks clarifies the transition from the Cold War system to network culture. The Cold War system was designed to maintain stability by simplifying complex relations and situations in terms ofa grid with clear and precise oppositions. [...] This is a world in which walls seem to provide security. Walls and grids, however, offer no protection from spreading webs; as webs grow, walls collapse and everything begins to change. [...] Whereas walls divide and seclude in an effort to impose order and control, webs link and relate, entangling everyone in multiple, mutating, and mutually defining connections in which nobody is really in control. As connections proliferate, change accelerates, bringing everything to the edge ofchaos. This is the moment of complexity. (23) We are firmly entrenched in this momentofcomplexity. Taylormarks the transition ofthe ColdWar/grid system to networkculture as beginning in 1989, which is six years after the emergence of computers in public school classrooms (1983) and five years after the fifth e (computers) made its debut at Conference on College Composition and Communica tion (eCCC) in New York(1984). In this paper I argue that the emergence ofcomputers in the classroomexacerbated the already prevalent issue of racial and class inequity in education.'

It is attached inextricably to the world offood, shelter, and human equality. [...] To elucidate the violence ofliteracy is to understand the


The study described here investigated the effectiveness of relaxation training and systematic desensitization when used as stress reduction techniques with professional and paraprofessional persons working with severely behaviorally disordered adolescents. The 14 professionals and paraprofessionals in the sample were randomly assigned to an experimental or control group. The experimental group was instructed in relaxation training and systematic desensitization, while the control group participated in restraint training and other aggression management activities. There appeared to be a significant reduction in stress among those in the experimental group.

Hot pepper is widely used as seasoning on Asian countries. Especially, South Korea has various kinds of hot pepper food product such as various Kim-chis, hot pepper pastes, soups, and other dishes. Those contain sliced or powdered hot pepper to enhance hotness in dishes. As Korean food getting popular in world wide, the content of hotness needs to be measured and controlled. Capsaicinoids is a chemical material which contributes to hotness of pepper. Quantitative analyze method on capsaicinoids needs extraction, separation, and HPLC (high performance liquid chromatography) analysis. It is time consuming, expensive, and expert needed method which is not appropriate to apply during online food process. Therefore, to analyze in easy and fast way, near-infrared analysis on capsaicinoids from hot red pepper was conducted. 14 kinds and 10 of each kind of red hot pepper, totally 140 samples were powdered and sieved into 500um particle. Those of half were mixed with seeds and the other was not. Reflectance (892~1695nm) spectrum of those powder were acquired with specially made probe holder. Capsaicinoids' concentration was analyzed conventional method. Data preprocessing such as baseline correction and 1st derivative were conducted before PCR (principal component regression) and PLSR (partial least square regression) analysis and cross validated. Determination coefficient of validation showed 0.9702 and 0.9029; SECV as 23.65 and 43.05 respectively to PCR and PLSR.

This project presents preliminary results of a pilot project in which an American native speaker of English interacted live with English- language classes in Taiwan via Internet teleconferencing. Initial student reaction was positive. Quantitative and qualitative evaluation indicated an increase in motivation, ability, and confidence as a result of the interactions. Students cited several elements of the instructional design in explaining their increased proficiency: the sessions' emphasis on subjects interesting and pertinent to young adults, including American culture and traditions; spontaneous and authentic interaction with a native speaker; and the implementation of techniques to lessen anxiety. While preliminary, the positive results suggest a new avenue for foreign language instruction around the world that makes use of student-centered, active learning.

The presence of microorganisms have been shown to increase by over 40% the mass transfer rates from small oxygen bubbles at low Reynolds number flow. This increase was found to be due only to the microbe cells as inert particles disrupting the quasi‐static liquid surface film surrounding the gas bubble and thus decreasing the gas‐liquid interfacial resistance. The observed increase in oxygen mass transfer rates was not dependent on cell viability, no effect was noted due to cell‐liquid interfacial resistance, nor was the phenomenon due to altering the physical properties of the liquid during cell propagation. These results were obtained in a unique plexiglass apparatus designed for observing under a microscope a small (0.4 mm dia.) stationary oxygen bubble collapsing into a flowing fluid. The oxygen bubble was injected by a small hypodermic needle and the fluid was suspensions of the yeast Candida intermedia, the bacterium Pseudomonas ovalis, 0.3μ alumina, as well as base points of cell free broth and pure water. Several well‐known chemical inhibitors of oxidative phosphorylation were used to limit cell oxygen uptake. Calculations of oxygen mass transfer rates were compared with the semi‐empirical model of Frössling, the circulating sphere model of Levich, and the rigid sphere concentration boundary layer model of Fried‐lander, the latter two showing strong Reynolds number dependence that may be due to radial fluid motion.
