The renewable refractory material can be homogenized in batches, and the main-composition index fluctuation range of the homogenized renewable refractory material is reduced from original 10% to 4%.


Recent researches indicate that traditional plant may act as a wound healing agent, one of them is Karamunting leaves. The aim of this research is to find out the effect of 70% ethanol extract ointment of karamunting leaves on re-epithelialization of incision wound healing on wistar ratrs skin. This research was an experimental research with post-test only control group design. The research subjects were twenty male wistar rats in which further divided to five groups; positive control group (sanoskinr ointment), negative control group (placebo ointment), experimental group 1 (2,5% karamunting leaves ointment), experimental group 2 (5% karamunting leaves ointment) and experimental group 3 (10% karamunting leaves ointment). All groups underwent 2 cm long incision at the back with 0,2 cm depth, parallel with os.vertebrae, within 5 cm from the ear.On the tenth day, wound tissue were taken from all groups sample and processed into histological blood smears stained with HaE to check the thickness and the width of the slit skin epithelium observed with 10x objective lens magnification. The 70% ethanol extract ointment of leaves Karamunting decreased slit thickness epithelium (pl0,05) and minimized slit width epithelium (pl0.05) compared to negative control. 70% ethanol extract ointment of leaves Karamunting increased wound re-epithelialization of incision wound on wistar ratrs skin with an effective concentration of 5%.n


Yu Ping Feng San (YPFS) is a classical TCM formulation which has been traditionally used for treatment of immune system related diseases such as chronic bronchitis, allergic rhinitis and asthma. The formula is a mixture of Radix Saposhnikoviae (Fangfeng), Radix Astragali (Huangqi), and Rhizoma Atractylodis macrocephalae (Baizhu). TLCand LC-DAD-ESI-MS/MS methods have been developed for the analysis of the metabolic profiles of the single herbs and of the formula. Decoctions and ASE extracts were analyzed in order to trace components of the individual herbs in YPFS. Nine constituents of Radix Saposhnikoviae, ten constituents of Radix Astragali and five constituents of Rhizoma Atractylodis macrocephalae have been assigned in the chemical profiles of the formula, which now allow the standardisation of YPFS. The pharmacological testing showed that all extracts significantly inhibited expression of TNF, IFN, and IL-1 in U937 cells, while the inhibition of IL-4 was consistently low. Compared to conventional


This paper aimed to perform a preliminary study on real-time regulation of filling speed by considering multiparameter synergistic coupling effect in fused deposition modeling. Bivariate experiments and sampling printing tests on designed samples, under different parameter combinations which are made up by filling speed, layer thickness, nozzle temperature and corner angle, were carried out to build and validate a real-time regulation model of filling speed by employing error analysis and multivariate nonlinear regression method. Results showed that the equivalent dimensional deviation values and area deviation values of Sample A, Sample B, Sample C by using real-time regulation algorithm of filling speed are lower than or close to the concentrated averages by using the optimal constant filling speed, with the maximum of 0.32 mm and 0.46 mm2. Actual and theoretical build time of Sample D at real-time regulated filling speed are less than those at 20 mm/s ("low speed"), and close to those at 45 mm/s ("medium speed") or 70 mm/s ("high speed"), which indicates that the method of real-time dynamic adjusting filling speed can not only improve printing accuracy, but also give a full consideration to printing efficiency at the same time.

One may draw a considerable satisfaction at the rate and quality of growth, as well as development of psychiatry in our country, yet there are areas where a little special attention may mean a timely step in the right direction but more important at the right time. We believe that one such area relates to the problems of adolescence. We are aware that adolescence is phase of human development characterized by the onset of puberty and accompanied by adolescent turmoil. Inspite of this awareness and having ourselves experienced the phenomenon, it is quite surprising that persons in later life often fail to comprehend the particular problems often posed by adolescents. The reason for this may not be difficult to understand because of (i) suddenness of the onset of adolescence produces a sudden change in a child who is usually well adapted to his environment at the end of "latency period", (ii) degree of change (both quantitatively and qualitatively) and instability in behaviour, and (iii) conflict with societal norms and figures of authority. As a consequence there is a tendency to view disruptions of adolescence as deviations from the norm. Undoubtedly controversy exists with regard to the incidence and significance of disturbances in adolescence and thus a need to delineate problems of adolescence in normative and psychiatric terms. Though it is quite difficult to describe adolescence and adolescent turmoil in terms of normality—simply due to the extreme variability of picture—a closer look would reveal that underneath this variable picture a relatively unvarying picture is discernable. This is constituted by forces which are a strange and perplexing (both to an adolescent and to an adult) conglomerate of various, and quite often contradictory, emotions, actions and behaviours. An adolescent is in a twilight zone of childhood clinging and adult grouping, a period of transition characterized by impulsiveness, impatience, acting out, and a mixture of diverse, opposite and extreme feelings. Confusions, instabilities, and uncertainties prevail. Sense of identity is put to test. Emotions fluctuate between love and hate, sadness and excitement, and infatuation and disenchantment. There is a tendency to experiment with sexual and aggressive impulses, and a desire to change and refusal to change. The sense of belonging which was previously related to the family is now sought beyond the family in social ties that require different criteria for membership, acceptance and identity. It should be apparent that as long as these forces, …


[1] The jumps in seismic velocity and density near 410- and 660-km depths have been postulated to mark phase changes in a locally, chemically homogeneous mantle. Seismic estimates of upper mantle discontinuity thickness and lateral variability have varied, posing difficulties for assessing models with chemical and phase transition layering. Observations of underside high-frequency (∼1 Hz) P wave reflections from the 410- and 660-km discontinuity that precede the P′P′ phase provide unique constraints on the physical properties of these dynamically critical features. We have collected high-quality recordings of P′P′ and its precursors from three sources: the California Seismic Network, the Large Aperture Seismic Array in Montana, and the Global Seismic Network. The array and regional network data have great sensitivity to weak P′P′ precursors, whereas the global network recordings have good geographical distribution of bounce points. The only consistently observed reflections originate from depths near 410 km and 660 km. The reflector observed near 520-km depth with longer period waves, which has been interpreted as the olivine β–γ phase transition, is too small in impedance contrast or too thick to reflect 1-Hz P waves. Data from all three networks indicate that the 1-Hz P waves from the "660" are bigger than those from the "410." Although large variability in P′P′ and its precursors' amplitudes prevents strong conclusions, we show that the P′P′ precursor amplitudes, travel time dispersion, and frequency content are consistent with a sharp (≤2 km) 660 and a more diffuse 410, consistent with mineral physics predictions.


Histological images of the cutaneous tumour, abdominal mass and lymph node were similar. The neoplasia consisted of large, lymphoid cells with moderate to abundant cytoplasm and large, irregular, sometimes lobulated nuclei with prominent nucleoli. In the skin, neoplastic cells eroded and infiltrated the epidermis. The lymph node showed a characteristic subcapsular and sinusoidal pattern of infiltration by neoplastic cells. Despite chemotherapy the patient passed away 5 months after the initial cytological diagnosis of lymphoma. That patients receiving immunosuppressive therapy after transplantation have an increased incidence of neoplastic diseases, especially non-Hodgkin's lymphomas, is a well-known fact. Most post-transplant lymphoproliferative disorders (PTLDs) are of B-cell derivation and have a strong association with EBV. They have a predilection for extranodal sites, a varied morphological appearance, frequent absence of evidence of monoclonality and a variable prognosis. T-cell PTLDs are uncommon. Several reports describe their clinical and pathological characteristics. Few cytological descriptions on PTLDs are available. As expected from histopathology, these study groups highlight the variability of the cytologic image. A spectrum of disorders ranging from polymorphic atypical lymphoid proliferations to more monomorphic large lymphoid cell neoplasms can be seen. T-cell PTLDs have been recently, reviewed. As opposed to their B-cell counterparts, T-cell PTLDs are rarely associated with EBV, and most are monoclonal. Due to prognostic and therapeutic considerations, it is important to differentiate between conventional lymphomas and B-cell and T-cell PTLDs.


We study the worst-case error of multivariate integration in weighted Korobov classes of periodic functions of d coordinates. This class is defined in terms of weights ?j which moderate the behavior of functions with respect to successive coordinates. We study two classes of quadrature rules. They are quasi-Monte Carlo rules which use n function values and in which all quadrature weights are 1/n and rules for which all quadrature weights are non-negative. Tractability for these two classes of quadrature rules means that the minimal number of function values needed to guarantee error ? in the worst-case setting is bounded by a polynomial in d and ??1. Strong tractability means that the bound does not depend on d and depends polynomially on ??1. We prove that strong tractability holds iff ?∞j=1?j 0 there exist lattice rules that satisfy an error bound independent of d and of order n??/2+?. This is almost the best possible result, since the order n??/2 cannot be improved upon even for d=1. A corresponding result is deduced for weighted non-periodic Sobolev spaces: if ?∞j=1?1/2j 0 there exist shifted lattice rules that satisfy an error bound independent of d and of order n?1+?. We also check how the randomized error of the (classical) Monte Carlo algorithm depends on d for weighted Korobov classes. It turns out that Monte Carlo is strongly tractable iff ?∞j=1log?j<∞ and tractable iff limsupd?∞?dj=1log?j/logd<∞. Hence, in particular, for ?j=1 we have the usual Korobov space in which integration is intractable for the two classes of quadrature rules in the worst-case setting, whereas Monte Carlo is strongly tractable in the randomized setting.

SUMMARY Four grass species, three hybrids and three mixtures were grown in field swards near Aberystwyth. All swards were amply supplied with nutrients and were cut at 5-week intervals during the year of sowing (1989) and during the following 4 years. The order of the grasses in rate of establishment was: Westerwolds ryegrass > Italian ryegrass (Lolium multiflorum) > Italian ryegrass × perennial ryegrass, Italian ryegrass × meadow fescue, perennial ryegrass (Lolium perenne) > perennial ryegrass × meadow fescue, meadow fescue (Festuca pratensis) > tall fescue (Festuca arundinacea). During the sowing year as a whole, Italian ryegrass was the highest yielding grass, followed by Westerwolds ryegrass. During the remaining period (1990–93), as a whole, the highest yields were obtained from perennial ryegrass sown alone or in a mixture with tall fescue. Tall fescue sown alone was one of the lowest yielding grasses in the year of sowing, but developed to be the highest yielding in 1992 and 1993. Westerwolds ryegrass persisted least well, although some plants did survive until 1992. Italian ryegrass persisted better than Westerwolds and Italian ryegrass × meadow fescue persisted better than Italian ryegrass. Hybrid ryegrass and perennial ryegrass × meadow fescue persisted satisfactorily but with fewer tillers/m2 than perennial ryegrass or tall fescue. The yield of tall fescue in March was as high as that of Italian ryegrass in 1990 and 1991 and higher than that of any of the other grasses in 1992 and 1993; the tiller density of tall fescue was particularly high in March. The yield of mixtures (Italian ryegrass with perennial ryegrass, Italian ryegrass with tall fescue and perennial ryegrass with tall fescue) was, on average, 2·5% more than the mean of the component species when sown alone. When grown with ryegrass, tall fescue was not prominent initially but its proportion in the sward gradually increased.

S-parameters of electrical networks are often extracted using an electromagnetic (EM) simulator, and imported directly or after conversion to rational function models into a transient circuit simulator. However, there are several issues related to frequency-defined models that might prevent successful transient simulation. In this work, the requirements for S-parameter and rational function models in the frequency domain leading to successful transient simulations are studied in detail. Application examples of corrupted transient simulation results due to failure to meet these requirements are presented. This work also presents a quality assurance methodology to ensure that S-parameter and rational function models satisfy such necessary requirements. In particular, a new method is proposed to check the DC values of S-parameters obtained from EM simulation.


DC, RF and noise parameters of GaAs pHEMTs with 100 nm gate length and widths (μm) of 2×10, 2×15, 2×25, 2×50, 2×75, 4×50 were investigated with the focus on test structure with gate width of 2 × 50 µm. Using a Maury Microwaves ATS system in the 8–50 (K, K<inf>a</inf>), 50–75 (V) and 75–110 GHz (W) frequency band, the noise parameters were measured and calculated employing the Y-Factor method. The sources of measurement uncertainties are discussed. Very good repeatability the measured minimum noise figure (NF<inf>min</inf>) over gate-source bias (V<inf>GS</inf>) and scattered but very repeatable data over frequency were observed. Measured s-and noise parameters are analyzed with the Angelov compact model and also with small-signal model.


In the modern age the amount of digital information generated is extraordinary. Every interaction with the Internet and with social networks, every credit card transaction, every bank withdrawal, and every magazine subscription is recorded digitally and linked to specific users. This chapter discusses specific examples of technology affecting individual privacy that have developed in recent years or have become more sophisticated. The examples described are: identity cards, biometrics, communications, surveillance (video surveillance, closed circuit television (CCTV), unmanned aerial systems (UAS), internet surveillance, workplace surveillance, international surveillance, global positioning system (GPS) technology and radio frequency Identification (RFID) technology), and social networks. A combination of state regulation, as well as legal protections for the individual against both governmental and private parties, must be devised in order to keep up with the technology that makes possible unfettered invasions of privacy. Keywords:biometrics; communications; global positioning system (GPS); identity cards; individual privacy; radio frequency identification (RFID); social networks; unmanned aerial systems (UAS)


Today network security, uptime and performance of network are important and serious issue in computer network. Anomaly is deviation from normal behavior which is factor that affects on network security. So Anomaly Extraction which detects and extracts anomalous flow from network is requirement of network operator. Anomaly extraction refers to automatically finding in a large set of flows observed during an anomalous time interval, the flows associated with the anomalous event(s). It is important for root cause analysis, network forensics, and attack mitigation and anomaly modeling. We use meta data provided by several histogram based detectors to identify suspicious flows, and then apply association rule mining to find and summarize anomalous flows. Using Histogram based detector to identify anomalies and then applying Association rule mining, anomalies will be extracted. Apriori and FP Growth algorithm will be used to generate the set of rule applied on metadata. Using traffic data from a network this technique effectively finds the flow associated with the anomalous event(s). it triggers a very small number of false positives, which exhibit specific patterns and can be sorted out by an administrator this anomaly extraction method significantly reduces the work hours needed for analyzing alarms, making anomaly detection systems more practical.

Meteorological parameters, as the important basis for improving building energy efficiency, will show apparent changes under climate change conditions. In this study, outdoor design temperature and humidity for air‐conditioning system in 12 cities, representing major climatic zones of China, were analysed to determine the impacts of temperature and humidity on the design load of air‐conditioning system. The results showed that outdoor design temperature largely increased during the last few decades and relative humidity apparently decreased except for two cities belonging to the severe cold and hot summer and cold winter climate zones. The increase in temperature and decrease in humidity have made obvious changes in the design load of air‐conditioning system. The design loads for cooling increased 1.8%–10% in these selected cities during 1991–2017 compared with 1961–1990. By contrast, the design loads for dehumidification decreased 0.8%–7% in 1991–2017 relative to 1961–1990. When the cooling and dehumidification were considered together, the design loads changed from −1.5% to 4.1% in the two periods, depending on cities or climate zones. These results demonstrated that, under the condition of climate change, the combined changes of humidity and temperature rather than temperature alone should be fully considered to determine the design capacity of air‐conditioning system, especially for temperature and humidity independent control (THIC) air‐conditioning system, to save energy and improve indoor comfort.

Theoretical models of stars in the mass range of ..beta.. Cephei stars have been computed with Carson's new radiative opacities from the zero-age main sequence up to the stage of core helium ignition. The new models lying off the zero-age main sequence possess cooler effective temperatures than do models based on earlier opacities, and cross the observed ..beta.. Cephei strip in the H-R diagram only once. This intersection occurs during the main phase of core hydrogen burning. Nonadiabatic pulsational properties of the models during this phase of evolution have been derived in the linear approximation. The pulsation constants and period ratios for both radial (l=0) and nonradial (l=2) modes turn out to be systematically (though not largely) different from those possessed by models based on earlier opacities. Cases of two modes with close periods are pointed out that may possibly account for the ''beat'' phenomenon observed in many ..beta.. Cephei stars. The observed phase lag of 90degree between the light and radial-velocity curves is predicted correctly along the intersection strip for many of the modes. But all the modes that have been tested for actual instability, viz., those with 0< or =l< or =5 and 0.02< or =Q (day)


The paper discusses the structure of "V他个X"from three flat surfaces,analyses the difference between "V他个X"and the structure of typical double-objects sentence;there are two reasons for predicate words being direct object: one is the verb which can take predicate words offer possibility for predicate words being object,the other is "个"makes "X"became nominalization,and takes it into double-objects structure;"他"is the phenomenon of grammaticalization;the whole structure expresses future tense,and can enhance tone。


A novel process for fabrication of torsional micro-mirrors with large dimensions (300 X 240 micrometers and 150 X 120 micrometers ) is presented. The mirrors consist of a sputtered aluminum film on a layer of supporting oxide mounted on fully suspended single crystal silicon grids. The grids have an aspect ratio of 7:1 in order to provide a stiff backbone and to ensure flatness of the mirror surface. The mirrors thus do not bend due to the internal stresses. A new idea of actuation of torsional structures is also presented in this paper. Vertical near-comb type actuators were fabricated to drive the torsional structures.

We sought to understand parent stress related to mobilization by identifying parent, child, and therapy related factors and how parent mobilization …


This research is motivated by the fact that the level of literacy and inclusion of Islamic finance is still low in Indonesian society in general. Meanwhile, studies on Islamic finance literacy and inclusion among universities are still rare. Therefore, this study aims to reveal the level of literacy and inclusion of Islamic finance at the Banjarmasin State Polytechnic. The research method is quantitative-descriptive by using survey as a way of collecting data. The results showed that the level of Islamic finance literacy among Poliban employees was relatively good, while the inclusion rate was still low.


The article considers the prospects of using the innovation proposed by the authors to improve the level of safety and comfort of the school educational environment. The relevance of the study is due to the law "On Education in the Russian Federation," aimed at further humanization of the educational process. The characteristics of the author's project - "rooms of temporary solitude," which are designed as locked from the inside single cabins with a chair and a pull-out table, where any student can retire during the break. It is noted that these rooms should not be confused with the so-called "sensory rooms" (or "relaxation rooms"), which perform more functions and do not require the presence of only one person. In the practical part, the results of a written survey of students in grades 7-9 are analyzed, allowing to see the needs of students in solitude between the lessons and their attitude to the proposed innovation. It is shown that "temporary privacy rooms" in Russian schools is supported by more than half of the test participants - 53.3 %. The share of respondents seeking or at least inclined to visit such booths is 46.4 %. The reasons why students want to make a change alone are given.

The Climate Leaf Analysis Multivariate Program (CLAMP) is an established methodology for physiognomic analysis of dicot leaf floras. This paper uses a meta-analysis of four studies that provide CLAMP data on 245 floras from Asia, Africa, and North and South America to demonstrate the application of a new analytical methodology for the exploration of the relationship between leaf morphology and environment. This methodology involves the application of a generalized "pairs" plot or scatter plot matrix (SPLOM), a form of graphical analysis for multivariate data. It is compared with the results from regression, hierarchical cluster analysis, principle components analysis, and canonical correspondence analysis. Analysis of the available data using pairs plots reveals extensive multiple covariation among explanatory leaf physiognomic variables and identifies sources of systematic error that eigenvector ordination methods tend to conceal. Pairs plots provide a supplementary method for analyzing complex multivariate data on leaf physiognomy and contribute to biological understanding of leaf–environment interactions. Because pairs plots allow more flexible investigation of multivariate data than existing eigenvector and regression-based approaches, they may prove useful not only for analyzing CLAMP data, but also in exploring multiple covariation in other complex paleontological data sets.


A Reggeon field theory is proposed using as an input two exchange-degenerate mesonlike trajectories, each of them corresponding to a pair of conjugate poles. A Pomeron and a lower-lying Reggeon are generated by spontaneous symmetry breaking. Both the input and output trajectories have a $\sqrt{t}$ dependence and are complex for $tl0$, reflecting the conventional treatment of Regge-pole-cut collisions. The gauge symmetry of the model is briefly discussed, and the model is compared with earlier work.


Since the capillary structures in the internal wall of heat pipe dominate the heat transfer performance, the research of surface heat functional structure is being gradually extended to the fields of metastructure and microstructure. This paper proposes a combined ploughing-extrusion method with a multi-tooth tool to form the micro-groove structures in the internal surface of copper pipe. Experiments indicate that the combined ploughing-extrusion process can create rougher surface than the single ploughing-extrusion process, and some phoenix-feather-like structures appear. The capillary force comparative experiment indicates that the heat pipe manufactured by the combined method can absorb 0.2ml more liquid than the one made by single process, supposing there is 90ml liquid in the container. The heat transfer testing experiment also indicates this heat pipe can transfer more heat when the inclination angle is small, but with the increase of inclination angle, this superiority becomes not so evident due to the increased reflow resistance. The combined process that comprises more than two processes makes metal yield and generates cracks in the internal wall.Copyright © 2007 by ASME

A survey of Meloidogyne in La Vera (Spain) was carried out during October 1995 and 1997. Isozyme electrophoresis (A-EST, MDH, CAT, GPI, DIA, GOT and SOD) was performed for each nematode isolate, each of which was cultured from an egg mass. In 1995 seven isolates of M. incognita, two of M. javanica and 75 of M. arenaria were found, while in 1997 one isolate of M. javanica and 72 of M. arenaria were found. Taxonomic relationships were established among 151 isolates using enzyme phenotypes by means of Multiple Correspondence and UPGM analysis. Twenty-six Multilocus Enzyme Electrophoresis (MLEE) phenotype variants were detected in ten significant taxonomic units: M. arenaria (seven units), M. incognita (two) and M. javanica (one). A total of 13 loci were identified and allelic frequencies for MLEE phenotype variants were estimated. Genetic distances among them suggested that M. arenaria is a poly- or paraphyletic group formed by at least two or three monophyletic lines of different origins. The evolutionary and epidemiological implications are discussed.


as Hsu Te-li, Hsieh Chueh-tsai and Lin Piao are summarily covered in a few hundred words each—too briefly to reveal much about them. Such "big-wigs" as Mao Tse-tung, Chou En-lai, Chu Te, Jen Pi-shih and Liu Shao-ch'i are mentioned only obliquely or inferentially—but these had received attention in Inside Red China, to which Red Dust is the belated supplement. It is not clear what the stories of minor characters—drama directors, boy actors, army doctors—contribute to informed knowledge of the Chinese Communist government. Robert C. North's introductory essay, "Communisrs of the Chinese Revolution," is a sound historical analysis of the revolution in China down to 1950, unhappily brief. He also compiled, as an appendix, thumbnail biographies of 27 of the most important political personalities in contemporary China, identifying them with official positions held as recently as 1950. These two additions contribute notably to the usefulness of the volume.


This paper presents a framework for model validation and calibration, while employing ERP systems' data and expert knowledge of Group Model Building sessions' participants. This framework was applied in the project for a staffing company, and I will use mini case studies from it to illustrate my approach. In order to build this model various sources of knowledge were used: statistical data, market reports, knowledge of company representatives obtained through interviews and group model building sessions, and system data stored in various IT systems. Combining those sources of information it is possible not only to get more knowledge about the system, but also validate and calibrate it. Based on this project experience and related literature some practical recommendations were developed and their applications demonstrated. Introduction Nowadays enterprises are overloaded with data, which is collected and stored in databases. More and more information is available for decision support. However, data analysis is not only time-consuming and demanding to computational resources, but also sometimes it is difficult to define which data is worth to collect and analyze, and which methods are applicable for particular analytical purposes. Since the arrays of data stored in Enterprise Resource Planning (ERP) systems are huge, people get lost in it and have problem to recall not only the figures, but also trends: is this value increasing or decreasing. While synthesizing data with expert knowledge, it can make more sense and consequently can lead to a better understanding of the system. Group model building has emerged as a methodology for not only gathering data from people, but also capturing their interpretations of the causality present in the system (Vennix, 1995). Moreover, group model building allows for overcoming the human's tendency of seeing pieces of the system instead of whole. There are several reasons for that. One of them is that "many people are not trained in systems thinking. Another is the limited information processing capacity of the human mind" (Vennix, 1995, p. 41).


The relations among language acculturation, biculturality, and psychological adjustment were studied in a sample of 54 young mainland Puerto Rican mothers. Participants were interviewed in the language of their choice concerning their level of symptomatology (i.e., depression, anxiety, somatization, hostility, interpersonal sensitivity), language acculturation, monocultural involvement (assessed by separate adherence to American and Puerto Rican cultural values), and dual cultural involvement (assessed by a combination of cultural values). Results indicated that biculturality significantly predicted adjustment above and beyond monocultural involvement. In addition, although biculturality and bilingualism were both significantly related to psychological adjustment, linguistic balance showed a stronger association with adjustment than biculturality. Findings are discussed in light of the family, cultural, and developmental context in which young mainland Puerto Rican mothers are embedded.


Both Enterococcus faecalis and Escherichia coli can undergo abrupt temperature transitions in nature. E. coli changes the composition of its phospholipid acyl chains in response to shifts growth temperature. This is mediated by a naturally temperature sensitive enzyme, FabF (3-ketoacyl-acyl carrier protein synthase II), that elongates the 16 carbon unsaturated acyl chain palmitoleate to the 18 carbon unsaturated acyl chain, cis-vaccenate. FabF is more active at low temperatures resulting in increased incorporation of cis-vaccenoyl acyl chains into the membrane phospholipids. This response to temperature is an intrinsic property of FabF and does not require increased synthesis of the enzyme. We report that the FabF of the very divergent bacterium, E. faecalis, has properties very similar to E. coli FabF and is responsible for changing E. faecalis membrane phospholipid acyl chain composition in response to temperature. Moreover, expression E. faecalis FabF in an E. coli ∆fabF strain restores temperature regulation to the E. coli strain. This article is protected by copyright. All rights reserved.

ST A R PA PE R Endometrial effects of tibolone in elderly, osteoporotic women Ettinger B, Kenemans P, Johnson SR, Mol-Arts M, Van Os S, Seifert W, Verweij PJ, Cummings SR Obstet Gynecol 2008;112:653–9 Objective. To investigate endometrial effects of tibolone administered to postmenopausal women for three years. Methods. A total of 3500 postmenopausal women aged 60–85 years with a uterus and with osteoporosis were randomly given 1.25 mg tibolone orally daily, or placebo. Endometrial thickness in all women was measured, and 635 women with vaginal bleeding or endometrial thickness more than 4 mm had biopsies. Results. In the first year endometrial thickness increased by 1 mm in the tibolone group, with no further increases during the next two years. Biopsies showed endometrial hyperplasia in ,1%. In 15% of women with an endometrial polyp, the tibolone patients were more than twice as likely to show hyperplasia within the polyp. A slight increase in grade 1 endometrioid adenocarcinoma was found among women receiving tibolone. Vaginal bleeding was 11% in the tibolone group and 3% in the placebo group. Conclusion. Tibolone treatment during three years minimally increased endometrial thickness, hyperplastic polyps, endometrial carcinoma and vaginal bleeding.


Forty-three isolates of P. halstedii races 300, 310, 330, 700, 710, 730 affecting sunflower in Krasnodar region were studied by means of 22 RAPD-loci. Primer P38 did not produce amplification in the studied isolates. The other primers produced a total of 92 fragments with an average frequency of 4.4 fragments per primer. Eight primers (L14, Y11, P28, P46, P5, OPM08, OPM20, OPJ15) were not polymorphic among the studied isolates. Thirteen primers (OPB07, OPB17,OPC08, OPC15, OPD 11, OPD 18, OPE 03, OPD 20, OPF09 OPG02 OPG05, OPG06, and OPJ13) allowed the identification of race 300 from the other races, based on the presence of amplified DNA fractions lacking in other races, or the absence of fractions typical for races 310, 330, 700, 710, 730. The resemblance measured between races 330, 700, 710 and 730, counted by means of Jacquard coefficient, was near 1.00. The resemblance between race 300 and the others was 0.29. Accordingly, the genetic distance (Dxy) between race 300 and the others was 0.71. These data suggested that local races 310, 330, 700, 710 and 730 in Krasnodar region could not originate from race 300. One primer (OPG06) showed intraracial polymorphism on the presence-absence of a fragment with a length of 1125 bp in all races, except 700 and 710. Monomorphic condition (invariable presence of the 1125 bp fragment) of locus OPG06 in race 710 isolates from five remote districts of Krasnodar region pointed to its stability. The monomorphic condition of this locus (invariable absence of the 1125 bp fragment) in race 330 isolates from Kanevskoy district and polymorphic condition in one isolate from Viselkovskiy district are discussed.


A Hamiltonization procedure valid for both singular and nonsingular mechanics is proposed. A comparison with Dirac's theory (for singular systems) is developed.


IL‐12 initiates the development of cell‐mediated immunity by promoting the differentiation of naive T cells into the Th1 phenotype, and is essential in the development of a Th1 immune response to the intracellular protozoan parasite, Leishmania major. The present study investigated whether IL‐12 is also required for the maintenance and effector function of an established Th1 immune response in L. major ‐infected mice. While neutralization of IL‐12 com promised the ability of a leishmanial antigen‐reactive Th1 cell clone to produce IFN‐γ in vitro, lymphnode cells taken from 2‐week L. major ‐infected mice were able to secrete IFN‐γ in an IL‐12‐independent manner. However, when a short‐term T cell line was established in vitro from lymph node cells, the production of IFN‐γ again became IL‐12 dependent. These results suggest that other factors may compensate for IL‐12 in vivo in promoting IFN‐γ production during L. major infection. To directly assess if IL‐12 was required in vivo for resistance to L. major, we studied the effect of IL‐12 neutralization on both a primary and secondary L. major infection in C3H mice. L. major infection in C3H mice is characterized by the development of a small lesion that heals by 8 weeks, and these animals are resistant to reinfection. As previously reported, administration of anti‐IL‐12 monoclonal antibody (mAb) during a primary infection led to severe disease. However, mice that had healed from a primary infection with L. major and were treated with anti‐IL‐12 mAb were as resistant as control animals. These findings suggest that once Th1 cells have developed, their effector function in vivo is independent of IL‐12, and that this independence is not due to an intrinsic property of the T cell, but to the microenvironment created by the infection.


The key problem of the network and information security is protect the computer system and network effectively. An open virtual experiment platform of the network attack and defence, which simulates network enviroment, is builded by virtue of Honeypot and Honeynet. The entire network is virtually contained on a single, physical, system.


Introduction: Globally, secondhand smoke (SHS) is responsible for 600,000 deaths in 2011, 75% of these affecting women and children. SHS is responsible for causing harm to the cardiovascular and respiratory systems. The only effective way to protect people from SHS is to provide a 100% smoke-free environment. In Malaysia, Melaka is the first state that has implemented a 100% smoke-free city since 15 th June 2011. This article examines the impact of awareness, perception, attitude and behavior of smoking among people in Melaka following the Smoke-Free Melaka city (SFMC) policy and association of the awareness of the policy with perception of the social desirability of smoking and attitude towards smoking among adults. Methodology: A total of 1,039 adult survey from face- to-face interview was carried out in June 2012 within six zones in Melaka. Respondents were recruited using systematic intercept sampling. They were asked if they have noticed advertisements on SFMC and their perception about the social desirability of smoking. Changes of behavior of smokers were recorded. Descriptive analysis, univariate and multiple logistic regressions were applied by using SPSS version 18. Odd ratio and 95% CI were computed for each corresponding variable. Results: More than 70% of the respondents have noticed the Melaka Smoke-Free advertisements, namely, on posters/signage (92.5%), digital billboards (77.0%), newspaper/magazines (72.8%) and inside shop/store windows (73.8%). Multivariate analysis revealed that noticing the advertisements had significantly influenced discussion with family and friends (OR=1.21; 95%1.12, 1.31, p<0.000) and implementation smoke-free homes and vehicles (OR= 1.09; 95% CI 1.01, 1.18, p<0.022 and OR=1.19; 95% CI 1.09, 1.30, p<0.001 respectively). In addition, significant association was found between discussion with family/friends and implementation of smoke free vehicles (OR=1.51; 95% 1.09-2.09, P=0.014). Following the implementation of the policy, most smokers said that they would not smoke in the presence of the children (83%), non-smoking family members (76.7%), older non-smoking person (78.2%) and policy officers (86.6%). Conclusion: The implementation of the SFMC project has resulted in positive impact on perception, attitude and behavior of smoking on people who live or visiting the Melaka city. This project has shown the potential to reduce exposure to secondhand smoke in both workplaces and home.


Objective: To observe the effects of chronic hypoxia and/or systemic administration of recombinant murine interleukin-1 beta(rmIL-1β) on the expression of tyrosine hydroxylase(TH) in the rat carotid body(CB).Methods: Adult male Sprague-Dawley rats were divided into 8 groups: chronic intermittent hypobaric oxygen stimulation for 0,1,2 and 3 w groups,and chronic intermittent hypobaric oxygen exposure for 0,1,2,and 3 w paired with rmIL-1β injection groups.Immunohistochemistry and Western blotting techniques were employed to observe expressions of TH in the CB of all rats.Results: The expression of TH in the CB of the rats exposed to hypoxia for 1 w,2 w or 3 w were up-regulated compared with that in group exposed to hypoxia for 0 w.Compared with normal rat,rmIL-1β can up-regulate the expression of TH in the CB.The expression of TH in the CB of the rats exposed to hypoxia for 1 w or 2 w plus rmIL-1β injection were up-regulated compared with that in groups only exposed to hypoxia for 1 w or 2 w.Conclusion: Both chronic hypoxia stimulation and rmIL-1β can up-regulate the expression of TH in the CB.The expression of TH in the CB of the rats exposed to hypoxia plus rmIL-1β injection were up-regulated compared with that in group only exposed to hypoxia.The result shows that either chronic hypoxia or proinflammatory cytokine IL-1β stimulation can promote the synthesis of catecholamines in the carotid body,and IL-1β can further promote the synthesis of catecholamines in the carotid body when the rats were exposed to chronic hypoxia.Proinflammatory cytokine might play a regulative role in the function of the carotid body sensing chronic hypoxia.

Hand detection is an essential step to support many tasks including HCI applications. However, detecting various hands robustly under conditions of cluttered backgrounds, motion blur or changing light is still a challenging problem. Recently, object detection methods using CNN models have significantly improved the accuracy of hand detection yet at a high computational expense. In this paper, we propose a light CNN network, which uses a modified MobileNet as the feature extractor in company with the SSD framework to achieve a robust and fast detection of hand location and orientation. The network generates a set of feature maps of various resolutions to detect hands of different sizes. In order to improve the robustness, we also employ a top-down feature fusion architecture that integrates context information across levels of features. For an accurate estimation of hand orientation by CNN, we manage to estimate two orthogonal vectors' projections along the horizontal and vertical axes then recover the size and orientation of a bounding box exactly enclosing the hand. Evaluated on the challenging Oxford hand dataset, our method reaches 83.2% average precision (AP) at 139 FPS on a Nvidia Titan X, outperforming the previous methods both in accuracy and efficiency.


This paper describes the development of a 25-DOF hand forward kinematic model based on optical motion capture data. In the proposed model, an evolutionary strategy method (ESM)-based optimization algorithm is proposed to determine hand link lengths based on measured surface marker motions in vivo. The Denavit-Hartenberg (D-H) method was employed to predict fingertip positions given hand postures. To evaluate the proposed model, an experiment was conducted in which a 3D motion analysis system was employed to measure the 3D positions of spherical retro-reflective markers placed at the hand surface landmarks during grasping a ball with a diameter of 50 ㎜. The predicted fingertip positions by the model were compared with those measured by a motion capture system. Compared with the SANTOSTM hand model, the proposed model had a smaller grand mean value of fingertip position prediction error (5.8 ㎜ for SANTOS and 2.7 ㎜ for the proposed model). The proposed model can be applied to computer-aided ergonomic design of hand-held devices.

Like other delphacids, Tarophagus colocasiae has a characteristic movable spur extending from the tibia, or fourth leg segment. Adults can be either capable of flight or have incompletely developed wings, leading to two separate morphological forms (Figure 1). Originally native to Southeast Asia, Indonesia, and islands in the Pacific Ocean, Tarophagus colocasiae was first discovered in the continental United States at a garden center in Winter Haven, FL in 2015 (Halbert and Bartlett 2015). No other species from its genus is currently found in the continental United States.

xB elements have been described as lymphoid-specific transcriptional activators. Here we show that xB elements are able to stimulate expression from test promoters more than 100-fold in T47D and 3T3 non-lymphoid cells. We also demonstrate that nuclear proteins from T47D cells form two prominent complexes with HIV xB sites. Since the complexes formed in nuclear extracts from T47D and PHA/PMA stimulated Jurkat cells comigrate in polyacrylamide gels, we suggest that the respective binding protein in T47D cells is either NF-xB or a closely related family member. In addition we provide evidence that NFl and xB elements can act synergistically to further increase transcriptional activity. INTRODUCTION Protein binding to the sequence GGGACTTTCC in the immunoglobulin x-chain gene enhancer (1) and the HIV-LTR (2) has been detected in mature B-cells (3) and phorbol ester activated T cells (2) and was correlated with transcriptional stimulation (1, 2). Therefore this sequence and its cognate binding factor(s) (NF-xB or related proteins) are important to the transcriptional activation of x-chain genes and the HIV-LTR in their respective target cells. In support of this, a restriction fragment (4) and oligonucleotides (5, 6) containing the xB sequence activate expression from heterologous promoters only in lymphoid cells. However, the functional presence of the sequence GGGACTTTCC in enhancers of other viral (7-9) and cellular genes (10, 11) and the presence of NF-xB like DNA-binding activity in activated fibroblasts (12) as well as in other non-activated non-lymphoid cells (13-17) suggests that this regulatory element and its cognate binding factors may be used more broadly in transcriptional regulatory circuits. Despite data from in vivo (1, 2, 4-7, 18, 19) and in vitro (8, 9, 13, 15, 20, 21) studies there is no consensus to which extent xB elements alone are capable of activating gene expression in non-lymphoid cells. Since these studies employed a number of different xB sites, enhancers and promoters, it seems possible that distinct transcription elements adjacent to xB sites within a given construct may contribute qualitatively and quantitatively to its activity. For example, the very potent enhancer of the HCMV IEI gene, which is active in numerous cell types, contains several xB sites embedded in binding sites for several nuclear proteins, including transcription factor NF1 (8, 9). To better understand the potential role of xB elements in non-lymphoid cells we studied the transcriptional activities of xB sites from the HIV-LTR in the context of the promoter of the mouse whey acidic protein (WAP) gene (22). This gene is expressed in vivo only in functional mammary cells (23, 24) and contains an array of protein binding sites including some for NFl-like transcription 8197 Volume 17 Number 2


This article historicizes ethno-religious and political conflicts in West Africa with Mali as a case in point. It looks at how foreign and donors' conditioned aid can pose a threat to the peaceful existence and survival of West African States. In fact, Mali has since its independence been beset by an extraordinary heavy burden of conflicts. It is either suffering from rebellions or political instability. Added to this, are the current religious problems which are undermining its territorial unity as a result of rising questions and distrust between northern and southern communities. This paper analyzes the reasons for the central authorities' opposition to the northern population, namely the Tuareg and Arabs, on the one hand, and the State to the military, on the other hand. It also brings to light the politically, religiously, and militarily roles of external stakeholder such as the neighboring and Gulf countries, France and the international community as it examines the causes and impacts of the political social and religious fragmentations using a historical perspective and provide for endogenous and exogenous solutions.


that Prosecutor is a coward in battle. Lanni argues that since every Athenian knew that there was a decent chance that he would have to defend himself (or prosecute others) in court sometime about something, every Athenian had an incentive to behave publically in a manner that was consistent with contemporary social norms: if he did not, it could be held against him in court. Third, Lanni demonstrates (chapter 5) that jury trials provided opportunities for Athenian citizens to publicize their current view of the normative underpinnings of old laws. Euphiletus, for example, famously argued (Lysias 1) that he justifiably killed Eratosthenes because he caught Eratosthenes in the act of committing adultery with his wife. And there was, in fact, an old law that permitted this type of homicide. But the nature of Euphiletus' arguments demonstrates that many Athenians, and thus the jurors in this case, might no longer be comfortable with it: they would perhaps prefer men to engage in nonlethal forms of self-help in such situations. We do not know what the trial's verdict was. But Lanni argues that whatever it was, it would have compelled men to think twice before they killed an adulterer, despite the fact that it would be formally legal for them to do so. And thus the behavior of individuals would be changed without changing the law. There is much to admire about this book. Lanni does a very good job analyzing the tremendous power of the law courts to enforce social norms, not just statutes: the arguments are cogent, honestly presented, and deeply engaged with a vast amount of scholarship, both on ancient Athens and modern law. This reviewer was particularly intrigued, however, with Lanni's discussion of the expressive effect of law. If we want to understand the nature of the rule of law, we must appreciate (inter alia) the fact that laws can affect behavior without being enforced.1 I thus strongly believe that scholars should follow Lanni's lead and further explore the operation of that seemingly paradoxical dynamic in ancient Athens.


A substrate is transferred to a processing container, and a film formation raw material containing cobalt amidinate and a reducing agent containing a carbonic acid in a vapor phase are introduced into the processing container, thereby a Co film is formed on the substrate.


The objective of this work is to establish an online Library of Computational Benchmark Problems designed and solved by multibody dynamics researchers. This library will serve as a comprehensive reference for current and future generations of researchers and students. By sharing our computational experience, we will be aptly equipped to determine the most appropriate approach (model, formulation method, numerical procedure, software implementation, etc.) for a given problem. By including a wide variety of problems, from the didactic planar slider-crank mechanism to complex biomechanical models, our hope is that the library will become a useful resource for all members of our global research community, facilitating collaboration and cross-pollination of ideas. A prototype library has been designed with a comprehensive classification scheme that allows users to quickly identify benchmark problems related to their area of specialization. The capability to upload new simulation results for existing problems, propose new benchmarks, and search the database have been incorporated. The prototype is available at http://real.uwaterloo.ca/benchmarks/. Our hope is that the library will become a tool that supports the research of multibody dynamicists worldwide, helping to advance the state-of-the-art in our ever-growing field.


Relaxation in glass-forming liquids as measured by dielectric, by light- and by neutron-scattering experiments can be described with the aid of the conformon model. Conformons behave like bosons which display a photon statistics. Conformons are excited and can also be annihilated. They show a universal reduced energy density distribution, revealing their thermodynamic roots. Each relaxation mode is assumed to be directly connected with a distinct conformon. The coupling is described by an empirical power law. The actual relaxation time distribution is then obtained by scaling each relaxation mode with the same kinetic factor. The relaxation behavior of liquids is therefore self-similar, characterized by individual factors such as the relaxation power, the coupling parameter and the temperature of pressure dependence of the kinetic factor ("shift factor").

In this paper we present DYNAMIC, an open-source C++ library implementing dynamic compressed data structures for string manipulation. Our framework includes useful tools such as searchable partial sums, succinct/gap-encoded bitvectors, and entropy/run-length compressed strings and FM-indexes. We prove close-to-optimal theoretical bounds for the resources used by our structures, and show that our theoretical predictions are empirically tightly verified in practice. To conclude, we turn our attention to applications. We compare the performance of four recently-published compression algorithms implemented using DYNAMIC with those of state-of-the-art tools performing the same task. Our experiments show that algorithms making use of dynamic compressed data structures can be up to three orders of magnitude more space-efficient (albeit slower) than classical ones performing the same tasks.


Thin solid aluminum film thermal flow into submicron-sized periodic grooves fabricated on a silicon oxide substrate has been studied in situ by transmission electron microscopy (TEM). Preparation of an aluminum film on the substrate was carried out using an evaporator installed in the specimen chamber of a TEM. The aluminum film was then gradually heated in situ in the microscope. At temperatures around 878 K, the polycrystalline aluminum film on the surface of the substrate started to flow into the grooves, and eventually the grooves were filled with polycrystalline aluminum. At 933 K, the aluminum in the grooves melted. It was confirmed that thin-film thermal flow into the grooves took place in the solid state. It is suggested that a creep deformation of the film driven by surface tension is responsible for this flow.


The behavior of unidirectional (UD) and woven fabric (WF) laminates has been studied under low velocity impact using a 3D transient finite element code. The failure evaluation of the laminates used a failure function based on Tsai Hill criterion. The studies were carried out for both simply supported and clamped boundary conditions with plate geometry 150 x 150 x 8 mm. Incident impact velocity of 5 m/s and impactor mass of 50 gm were considered. It was observed that the failure function is lower for WF laminates than for UD laminates indicating that WF laminates are more resistant to impact damage.

The search for quality education within the context of the emerging global village has resulted in education systems across the world sharing many characteristics. Characteristics include an economic rationale for transforming education, an emphasis on standards, the need for valid and reliable indicators of performance as well as issues relating to accountability (Smith and Ngoma-Maema, 2003). Monitoring of and feedback on learner performance provide important information to politicians and the public alike, and in the 1990s, monitoring of education systems became a major policy issue (Husén and Tuijnman, 1994). Here monitoring refers to the procedures for the collection of information about various aspects of the education system at national, regional and local levels (Husén and Tuijnman, 1994), with the main purpose of monitoring performance being to support learning or make judgements on achievement. South Africa faces many challenges related to its quality of education whilst recovering from the apartheid past (Howie, 2008). In an attempt to contribute to the improvement of education nationally, the Centre for Evaluation and Assessment (CEA) at the University of Pretoria, in collaboration with the Curriculum, Evaluation and Management Centre (CEM), at the University of Durham in the UK, embarked on a research project in 2003. The National Research Foundation (NRF), a national funding body in South Africa, funded this project in order to investigate and develop appropriate monitoring systems via, at primary level, the South African Monitoring system for Primary schools project (SAMP); and for the secondary school component, the South African Secondary School Information System (SASSIS) (see Scherman, 2007 for more details). The aim of the monitoring systems was to provide information about the quality of education that learners receive, and more specifically the extent of academic gains made by intervening at the proper time and effectively in learner development. Additional funding was obtained by the South Africa Netherlands research Program on Alternatives in Common Wealth-01-p.qxd 23/8/12 12:38 Page 100


The Arithmetic Cube II (AC II) is a digital signal processing system, designed to compute the discrete Fourier transform and cyclic convolutions. The architecture is the first which implements the so-called small-n algorithms. It is capable of computing a 1008 point complex-in, complex-out DFT in 3.5 ms., a rate equivalent to commercial systems running at much higher clock frequencies.
University-build systems such as the AC II, although currently rare, demonstrate that it is possible for universities to build complete systems, from custom chips to user-level software. This situation will result in numerous advances in computing as application specific systems are designed and built to solve old problems in new ways. Although the AC II's primary purpose was as a proof of concept design of a small-n algorithms architecture, the goal of demonstrating a complete system seems greater in comparison.
One of the key design problems which faced the author was where and how to transpose the two-dimensional matrices which are the AC II's data. It turned out that the best place for performing the transposition operation was within the memory sub-system. The design work on the memory sub-system of the AC II led the author naturally to searching for transposition and rotation architectures for other architectures. Transposition can become significantly more difficult for more general dataflows. This thesis shows that the problem of matrix transposition can be solved AT$\sp2$ optimally by a VLSI architecture which is completely systolic and has very simple control requirements.
This thesis also shows that the transposer architecture may be extended to handle the rotation of multi-dimensional cubes (matrices). This is a critical sub-operation in multi-dimensional signal processing problems. The resulting VLSI architecture is also AT$\sp2$ optimal for cube rotations. Both architectures are completely programmable as to the length of dimension of the input. In addition, the rotator is programmable as to the number of dimensions. The additional routing network required by the rotator may be mapped directly onto the routing network of the transposer; only additional control logic is required.


The conduction of electrons through narrow channels formed on the surface of liquid helium is analyzed by numerical simulations. It is shown that, when electrons are strongly coupled, we have nonlinear and even negative dependence of conductance on the width of the constriction which is controlled by the gate voltage (© 2011 WILEY‐VCH Verlag GmbH & Co.

In this paper, a remote monitoring system enabled with the smart internet of things (IoT) station for ambient assisted living (AAL) and smart environments is introduced. IoT station that is based on Waspmote platform to work as an intelligent device for capturing the data and transfers through 3rd Generation (3G) cellular module to the cloud by avoiding redundancy. The complete architecture of the developed ubiquitous monitoring system for AAL is elaborated with the process flow. The video camera sensor board with a presence sensor is connected to the Waspmote to take a snapshot or a video clip when there is any movement in the surrounding. The IoT station with the sensor board have a capability to detect and take picture even in a dark environment. The Waspmote generate message as soon as the motion sensor is triggered and send the image to the storage server using file transfer protocol (FTP) or the file transfer protocol secure (FTPs) over cellular communication. The recent related work is reviewed and discussed to show the advantages of the proposed design. Furthermore, the real testbed experiment presents the efficiency of the cellular IoT based monitoring system.

The fine structure and size of bainitic ferritic subplates in bainitic steels were investigated and analyzed with high resolution electronic microscope.The results show that crystal structures between beinitic ferritic subplates of casted air cooling and forged air cooling are determined.There is obvious orientation relationship of the twins between bainitic ferritic subplates.The twin subplate widths of upper bainitic ferrite are 2-30nm and the minimal twin subplate widths of upper bainatic ferrite are accurately determined as between 2-5nm.The interface between twin subplates is not parallel,but it is consisted of ledges from terraces with twin planes(11 2).


For managing spectrum effectively in cognitive radio system, a channel allocation mechanism based on repeated multi-bid auction is proposed, which uses three different channel allocation rules:max throughput rule, utility fairness rule and time fairness rule. Finally, the performance of the allocation mechanism is verified by simulation results, and the simulation results show that the mechanism for max throughput rule can maximize the total throughput of the CR system, the utility fairness rule-based mechanism ensure proportional utility fairness, while the mechanism for time fairness rule can increase the fairness of transmission, reduce the average transmission time and balance the delay of packages.


An array of random variables, indexed by a multidimensional parameter set, is said to be dissociated if the random variables are independent whenever their indexing sets are disjoint. The idea of dissociated random variables, which arises rather naturally in data analysis, was first studied by McGinley and Sibson(7). They proved a Strong Law of Large Numbers for dissociated random variables when their fourth moments are uniformly bounded. Silver man (8) extended the analysis of dissociated random variables by proving a Central Limit Theorem when the variables also satisfy certain symmetry relations. It is the aim of this paper to show that a Strong Law of Large Numbers (under more natural moment conditions), a Central Limit Theorem and in variance principle are consequences of the symmetry relations imposed by Silverman rather than the independence structure. To prove these results, reversed martingale techniques are employed and thus it is shown, in passing, how the well known Central Limit Theorem for U-statistics can be derived from the corresponding theorem for reversed martingales (as was conjectured by Loynes(6)).


In order to discuss a series of issues surrounding financial development and economic growth, it makes it more meaningful to discuss regional financial development and economic growth. This article aims to study the empirical study of the relationship between financial development and economic growth based on intelligent algorithms based on wireless network communication. In this article, a two-side positioning model is established, and the optimal solution is found for the feasible region through the particle swarm optimization algorithm. After two anchor nodes are realized, the position of the unknown node can be calculated. In addition, this article uses the Shadowing model to calculate the distance between wireless network nodes. This model is composed of path loss and occlusion factors, which can fully consider the impact of environmental factors on the signal. Experimental research data show that the improved algorithm has a positioning coverage close to 100% when the anchor node density is 30%. The improved algorithm in this article speeds up the convergence speed than positioning algorithm 1 and reduces the time by about 35%. Although the running time of the algorithm in this article is longer than that of positioning algorithm 2, the overall positioning accuracy is higher than that of the positioning algorithm, which is about 20% higher.


In this article, I, as a subaltern, offer a reverse gaze on White security plans to rescue the world from the tide of violent extremism. Violent extremism has been identified as a global security threat by the United Nations, which announced a Plan of Action to combat the threat in 2016. Education has been considered a valuable tool for preventing violent extremism. In 2017, UNESCO published a policy guide explaining how education can be used to prevent violent extremism. This article offers a critique of the UNESCO policy guide, using the construct of White ignorance as explained by Charles Mills and Jennifer Mueller's Theory of Racial Ignorance. This critique, coming from a location (Pakistan) where education has been under intense White scrutiny since 9/11, owing to its alleged link with violent ideologies, provides an inverse perspective on the problem of violent extremism. Using Mills's concept of the epistemology of ignorance, I argue that international security policies view security as maintenance of White hegemony and refuse to listen to the people labelled as a security problem by White epistemic authorities. I contend that it is the White security policy that needs to be educated to prevent violence and maintain durable security.


Purpose To review our experience with the management of fragmented and retained pigtail percutaneous nephrostomy (PCN) tubes and to explore the reasons for the fragmentation. Materials and Methods We retrospectively reviewed our institute database from January 2006 to December 2011 for patients who had undergone retrieval of fragmented PCN tubes. We assessed the preoperative factors, operative technique, and post-operative outcomes. Results A total of seven patients (4 males and 3 females) had been diagnosed with fragmented PCN tubes. The mean age of the patients was 41.5 years. Of the seven patients, five required antegrade instrumentation by way of a percutaneous tract to remove the foreign body, mostly along with stone retrieval. One patient underwent ureterorenoscopy and pneumolithotripsy for a ureteric stone along with ureteroscopic removal of the PCN fragment. Another patient underwent nephrectomy of the kidney containing the PCN fragment because it had become nonfunctioning. All patients were free of stones and symptoms on follow-up. Conclusions A prolonged waiting period for definitive surgery, urinary infection, and associated stone disease are significant factors causing fragmentation of PCN tubes. Proper insertion techniques, regular timed changes of the PCN tube, appropriate care of the PCN tube, and early surgery for underlying stone disease are required to avoid this complication. Patients with retained PCN tubes can be managed effectively with antegrade or retrograde endoscopic techniques while definitive management of the primary pathology is carried out, without any additional morbidity.


Maintenance of cellular homeostasis during drug‐induced oxidative stress (OS) resides in transcriptional activation or induction of antioxidant genes that are Nrf2 dependent. Nrf2 is sensitive to reactive oxygen species which drive potentiation reactions. We examined Nrf2 expression and its possible links to OS and OS‐sensitive pro‐ and antiapoptotic genes during EtOH‐potentiated DCLF‐induced hepato‐ and nephrotoxicity. Female ICR mice were fed EtOH containing drinking water (3 to 6% for 4 wks with normal chow) followed by DCLF (150 mg/kg, po) on day 28. Mice were sacrificed 24 hrs later. Blood was collected for serum chemistry, and the liver and kidneys for tissue biochemistry and western blot analysis. Data indicated that EtOH exposure increased DCLF‐induced nephrotoxicity in the absence of significant hepatotoxicity. Gene expression analysis revealed increased expression of Nrf2 in EtOH, DCLF and EtOH+DCLF exposed organs consistent with proportionate increases in serum ALT, BUN, DNA fragmentation and OS. Histopathology disclosed increased incidence of apoptosis and necrosis consistent with changes in expression of bad/bax/bid coupled with decreased expression of bcl‐xL in EtOH+DCLF exposure. Induction of CYP450 isozymes has been considered the key to EtOH‐potentied xenobiotic‐mediated organ toxicity, there may be other mechanisms at the genetic level that can influence potentiation reactions.


Overlapped-speech is known to degrade performance in automatic speech systems. In this study, a sub-band speech analysis technique is proposed to detect overlapped-speech segments in single-channel multi-speaker scenarios (i.e., co-channel speech). Sub-band signals are obtained by decomposing the input speech using a gammatone filterbank. Filterbank outputs are then used to modulate the frequency argument of a sinusoidal carrier. We show that the spectra of these frequency-modulated signals, namely Gammatone Sub-band Frequency Modulation (GSFM) features, are more disperse in overlapped-speech segments compared to single-speaker regions. We quantify the dispersion rate to obtain a measure for the amount of overlapped speech in a given speech segment. Overlap detection experiments are conducted using the speech separation challenge corpus and GSFM features are compared to commonly used overlap detection features. Detection errors are reduced by a relative 50% across different signal-to-interference values ranging from 0 to 9 dB.


The low-profile shield volcano, Alba Patera, is located at the northern end of the Tharsis rise. Its general characteristics have been described by various workers (1,2,3). The very shallow profile and very wide extent of its volcanic products have led some to suggest it represents a style of volcanism peculiar to Mars (4). Crater dating suggests Alba reached its peak of activity around 1850m.y. ago (5), with a range of ages for its Volcanic units between 2300 and 400m.y. ( 6 ) , using the chronology of Soderblom ( 7 ) . While there is much uncertainty regarding calibration of crater ages for Mars, it is clear from transection/superposition relationships, that Alba is one of the older of Tharsis' major central volcanoes. The oldest volcanic units emerge from under the more recent lavas at substantial distances from the current summit which is situated close to the comple:: summit calderas (8). These ancient flows have the appearance of composite, sheetstyle and often lobate flows which are seen only on almost flat ground at distances in excess of 450km from the summit. These impinge onto the older units of Tempe and Mareotis Fossae and Ceraunius Fossae on the east and southeast and may be partly covered by aeolian materials. Long flow scarps formed by these lavas are detectable on both the east and west of the volcano. The source vents are not seen and it is presumed that these are by nature flood lavas extruded from fissures during the early stages of activity in the region and before centralised volcanicity became established. The main shield is built from a plethora of sheet flows, tubeand channel-fed flows, often of great length (i.e. lOOkrn -320km), while the youngest flows are shorter, narrow flows, often with levees (9). The youngest flows can be traced right up to the walls of the nested summit calderas and evidently were erupted from the summit region. These flows bury older a d areally more substantial flows which may have originated at the summit, but whose source vents/fissures are obscured by the later volcanic units. Nearly all of these flows post-date the arcuate graben which form a ring-fracture zone, focussed on the summit, and with a diameter of about 550km; however, on the western side of the volcano, some tube-fed flows may be seen to be younger than short sections of some faults. The calderas themselves are composite; the younger is complete but the older is not, the products associated with vents focussed on the younger caldera having covered much of its eastern half. The presence of these large complex structures bears witness to a prolonged phase of summit tumescence and deflation, the cyclic process being produced by magma build up beneath the summit region, presumably in fairly shallow storage chambers, to give inflation, followed by withdrawal of magma during eruption, and concomitant summit deflation. On Earth, the dimensions of caldera structures is normally closely related to the size of the underlying magma chamber (10) which has led wood (11) to

The data of micro-climate in two typical wetlands,namely Aershan and Dalinor wetlands in the Autonomous Region of Inner Mongolia was analyzed and compared with the climate data nearby meteorological stations.The conclusions were as follows: 1) The cold-humid effect in both wetland was remarkable;2) The rainfall precipitation was mainly affected by regional climate(namely macro-climate) instead of micro-climate;3) The cold-humid effect in the Aershan wetland located in the humid area was more obvious than that in of the Dalinor wetland located in the semi-arid area;4) The micro-climate effect had tremendous impacts on the community structure and species distribution.The quantity of mesophyte and hygrophyte in the Aershan wetland were larger than that in Dalinor wetland.Whereas,the diversity index,evenness index and richness index in the Aershan wetland were distinctly lower than that in the Dalinor wetland.


We examine firm capital structure when heterogeneous agents optimally hold different claims, and control of the firm may change hands. When agents cannot commit to firm value maximization, controlling agents have the incentive to alter firm policy to maximize their preferred portfolio at the expense of other claim-holders. We consider settings that can include partial control rights to minority share-holders and/or debt-holders. In general equilibrium, the distortions relative to complete contracting are large even with small disagreement. However, it need not be the case that the distortions amplify the business cycle nor that stronger protection of debt holders mitigates the problem.

High precision isotopic measurements of Sn in two commercially available high purity materials and a previously analysed cassiterite from Straits Settlement, Malaysia, are presented as a basis for a new measurement procedure using the Micromass IsoProbe MC-ICP-MS. The results show that under optimised instrumental conditions two laboratory calibration standard solutions (Johnson–Matthey Puratronic Grade 1 Sn metal foil and Specpure ICP/DCP Sn solution) are isotopically identical and an external reproducibility of 0.000017 2 s.d. at 150 ppb Sn concentration (122Sn/116Sn 0.318597, n
= 14) can be achieved. An isotopic fractionation of +0.13‰/u (1.3 epsilon units) relative to these in-house standards has been verified for the cassiterite, which indicates a natural isotopic fractionation of approximately 2.8 times greater than the long-term reproducibility of the current optimised measurement procedure.

These technologies allow for more precise application of agricultural and livestock management inputs such as fertilizer, seeds


Arulmigu Kamatchi Amman Devasthanam in Penang is the sole Vishwakarma community temple in Malaysia, and it marks an entry into the world of Pathars; the traditional
Tamil goldsmiths, a sub-ethnic group within the local Indian diaspora. The conception
of this temple as "devasthanam" or "place of God", by the Pathars, implores this study
to explore this community temple as a place. This study frames the temple and the lived
experience a person has in it as a unit of analysis. The primary data comes from ethnographic study that involves participant observation and spatial study. The secondary data
is drawn from document and photo reviews alongside the writings of pioneering Indian art
historians. The findings of this study are chronicled as a narrative account to reveal this
temple as a dimension of the local Pathar community's lifeworld and to understand how
it develops into a locus that gathers human experience, insideness and identity formation
through the conception of Hindu temple as a synergy of form, meaning and use. The
findings of this study not only record this temple as a space of specific cultural continuity,
but highlights the need to recognize the diversity and differences within Indian diaspora
