Research and Design of Online Auction System Based on the Campus Network Using UML

As campus network and shopping online have grown up, the development of online auction system becomes integrity. The online auction system based on the campus network provides a trading platform for university students, and does not deal with the trading process. So the online auction system must increase its quality of service to attract students. In this paper, we present a scheme for the online auction system using the unified modeling language (UML) technique. We adopt the two steps to design the scheme, and the design scheme of the system is made up of use case diagrams, activity diagrams, class diagrams, sequence diagrams, deployment diagrams. In addition, the scheme can provide certain reference values for constructing the campus electronic commerce and realizing the digital campus.
Multilingualism and Multicompetence: A Conceptual View

The overall aim of this article is to argue that the functioning of every language system is basedon a potential multilingual competence. The empirical basis for this is now broad enough togain a comprehensive view on the overall competence of a multilingual individual. Moreover,increasingtheoreticalreﬂectionhasconferredanincreasinglyindependentproﬁleintheﬁeldof multilingualism research. In the main part of this article, a deﬁnition of multilingualism isproposed and related to the term “multicompetence. ” The proposed deﬁnition of multilin-gualism, emerging from sociolinguistically rooted studies, distinguishes not only the classicalsocial, institutional, and individual dimensions of observation but includes a new interactiondimensionaswell.Theterm“multicompetence”isthendiscussedinitshistoricaldevelopmentform on which psycholinguistics oriented studies. The European LINEE project tries to en-large the concept of multicompetence with the aim of making it suitable for a sociolinguisticembedding. This usage-based approach is presented and further claims for more conceptualreﬂections in the ﬁeld of multilingualism are made.THE TERM “MULTILINGUALISM” HAS estab-lished itself over the past two decades in linguis-tics. It is widely used and describes the variousforms of social, institutional, and individual waysthat we go about using more than one language.Included are not only varieties such as nationallanguages but also regional languages, minor-ity languages, migrant languages, sign languages,and, in the broadest sense, dialects. The area ofresearch is extensive and seems to be increasinglyexpanding; it is now time to clarify the deﬁnitionof multilingualism and multicompetence.This contribution has a conceptual vein; nev-ertheless, it is grounded on direct empiricalresearch, worked out mainly in the Europeanresearch network LINEE (Languages in a Net-work of European Excellence).
The transition from kindergarten to primary school, as experienced by teachers, parents and children in Hong Kong

This study investigates the transition from kindergarten to primary school through the experiences of the teachers, parents and children involved. Emphasis is given to the transitional activities participated in by the stakeholders and the effectiveness of these activities. These experiences of children's transition to school will inform further research into the design of effective transition programmes in the local context. The means of investigation in this study include questionnaires, semi‐structured interviews and observations. The results show that the teachers and parents generally believed that the children performed quite well academically, although the primary school teachers reported that they were average in discipline. The findings from both the questionnaires and the interviews show that most of the respondents agreed that strong connections between kindergarten, primary school and parents could facilitate a smoother transition to school. However, in reality, both kindergarten and primary school teachers showed ignorance of each other's teaching practices and curriculum.
Initial experiences with real-time elastography guided biopsies of the prostate.

PURPOSE Based on our first experiences with real-time elastography in the field of prostate diagnostics we evaluate its usefulness for biopsy guidance for prostate cancer detection. MATERIALS AND METHODS After imaging with conventional B-mode ultrasound in conjunction with real-time elastography 404 men underwent systematic sextant biopsy. RESULTS Overall prostate cancer was found in 151 of 404 cases (37.4%). In 127 of 151 cases (84.1%), prostate cancer was detected using real-time elastography as an additional diagnostic feature. CONCLUSIONS The results show that it is possible to detect prostate cancer with a high degree of sensitivity using real-time elastography in conjunction with conventional diagnostic methods for guided prostate biopsies.
Approximation Algorithms for Label Cover and The Log-Density Threshold

Many known optimal NP-hardness of approximation results are reductions from a problem called L abel -C over . The input is a bipartite graph G = (L, R, E) and each edge e = (x, y) ∈ E carries a projection πe that maps labels to x to labels to y. The objective is to find a labeling of the vertices that satisfies as many of the projections as possible. It is believed that the best approximation ratio efficiently achievable for L abel -C over is of the form N−c where N = nk, n is the number of vertices, k is the number of labels, and 0 Inspired by a framework originally developed for D ensest k-S ubgraph , we propose a "log density threshold" for the approximability of Label-Cover. Specifically, we suggest the possibility that the Label-Cover approximation problem undergoes a computational phase transition at the same threshold at which local algorithms for its random counterpart fail. This threshold is [EQUATION]. We then design, for any e > 0, a polynomial-time approximation algorithm for semi-random L abel -C over whose approximation ratio is [EQUATION]. In our semi-random model, the input graph is random (or even just expanding), and the projections on the edges are arbitrary. For worst-case L abel -C over we show a polynomial-time algorithm whose approximation ratio is roughly N−0.233. The previous best efficient approximation ratio was N−0.25. We present some evidence towards an N−c threshold by constructing integrality gaps for NΩ(1) rounds of the Sum-of-squares/Lasserre hierarchy of the natural relaxation of Label Cover. For general 2CSP the "log density threshold" is N−0.25, and we give a polynomial-time algorithm in the semi-random model whose approximation ratio is N−0.25+e for any e > 0.
Autoantibodies against the endothelial receptor of protein C are associated with acute myocardial infarction in young women

Summary. Background: Acute myocardial infarction (AMI) is rare among young women. The search for unknown risk factors is warranted. Endothelial protein C receptor (EPCR) is largely present at the endothelial surface of large arteries. No studies about association of anti‐EPCR autoantibodies (anti‐EPCR) with AMI are available. Methods: Plasma IgA, IgM and IgG anti‐EPCR levels were measured by enzyme‐linked immunosorbent assay in 165 women younger than 45 years who survived a first AMI and 165 healthy women, matched by age and geographical origin. Results: Using the 90th percentile of IgA anti‐EPCR in the control group, IgA anti‐EPCR were independently associated with AMI after adjustment for cardiovascular risk factors (OR 5.1; 95% CI 1.7–15.6; P = 0.004). The risk apparently conferred by IgA anti‐EPCR increased dose‐dependently (P for trend =0.0002). IgM anti‐EPCR were less consistently associated with AMI: a significant increase in the risk was found when women above the 90th percentile were compared with those in the lowest quartile (OR 3.6; 95% CI 1.2–11.5; P = 0.03). IgG anti‐EPCR were similar in patients and controls. A total of 145 patients underwent coronary arteriography. IgA or IgM anti‐EPCR were not different among patients with different degrees of atherosclerotic lesion (anova, P = 0.77 and 0.24, respectively). Conclusions: High levels of IgA and, to a lesser extent, IgM anti‐EPCR, are associated with AMI in young women.
Facebook's Privacy Trainwreck

Not all Facebook users appreciated the September 2006 launch of the `News Feeds' feature. Concerned about privacy implications, thousands of users vocalized their discontent through the site itself, forcing the company to implement privacy tools. This essay examines the privacy concerns voiced following these events. Because the data made easily visible were already accessible with effort, what disturbed people was primarily the sense of exposure and invasion. In essence, the `privacy trainwreck' that people experienced was the cost of social convergence.
New Methods for Metadata Extraction from Scientific Literature

Within the past few decades we have witnessed digital revolution, which moved scholarly communication to electronic media and also resulted in a substantial increase in its volume. Nowadays keeping track with the latest scientific achievements poses a major challenge for the researchers. Scientific information overload is a severe problem that slows down scholarly communication and knowledge propagation across the academia. Modern research infrastructures facilitate studying scientific literature by providing intelligent search tools, proposing similar and related documents, visualizing citation and author networks, assessing the quality and impact of the articles, and so on. In order to provide such high quality services the system requires the access not only to the text content of stored documents, but also to their machine-readable metadata. Since in practice good quality metadata is not always available, there is a strong demand for a reliable automatic method of extracting machine-readable metadata directly from source documents. This research addresses these problems by proposing an automatic, accurate and flexible algorithm for extracting wide range of metadata directly from scientific articles in born-digital form. Extracted information includes basic document metadata, structured full text and bibliography section. Designed as a universal solution, proposed algorithm is able to handle a vast variety of publication layouts with high precision and thus is well-suited for analyzing heterogeneous document collections. This was achieved by employing supervised and unsupervised machine-learning algorithms trained on large, diverse datasets. The evaluation we conducted showed good performance of proposed metadata extraction algorithm. The comparison with other similar solutions also proved our algorithm performs better than competition for most metadata types.
Uncovering the evolution history of data lakes

Data accumulating in data lakes can become inaccessible in the long run when its semantics are not available. The heterogeneity of data formats and the sheer volumes of data collections prohibit cleaning and unifying the data manually. Thus, tools for automated data lake analysis are of great interest. In this paper, we target the particular problem of reconstructing the schema evolution history from data lakes. Knowing how the data is structured, and how this structure has evolved over time, enables programmatic access to the lake. By deriving a sequence of schema versions, rather than a single schema, we take into account structural changes over time. Moreover, we address the challenge of detecting inclusion dependencies. This is a prerequisite for mapping between succeeding schema versions, and in particular, detecting nontrivial changes such as a property having been moved or copied. We evaluate our approach for detecting inclusion dependencies using the MovieLens dataset, as well an adaption of a dataset containing botanical descriptions, to cover specific edge cases.
Using Guided Notes to Improve the Academic Achievement of Incarcerated Adolescents with Learning and Behavior Problems

This investigation examined the effects of guided notes on the academic performance of seven students with learning and behavior problems, who were in a medium-security juvenile detention center. The findings of this study indicate that using guided notes could be an effective strategy for improving the academic performance of incarcerated youths with learning and behavior problems. The results of this study replicate earlier studies in which guided notes were used during whole-class instruction (i.e., Courson, 1989; Lazarus 1991, 1993; Pados, 1989).
Inducible Resistance to Maize Streak Virus

Maize streak virus (MSV), which causes maize streak disease (MSD), is the major viral pathogenic constraint on maize production in Africa. Type member of the Mastrevirus genus in the family Geminiviridae, MSV has a 2.7 kb, single-stranded circular DNA genome encoding a coat protein, movement protein, and the two replication-associated proteins Rep and RepA. While we have previously developed MSV-resistant transgenic maize lines constitutively expressing “dominant negative mutant” versions of the MSV Rep, the only transgenes we could use were those that caused no developmental defects during the regeneration of plants in tissue culture. A better transgene expression system would be an inducible one, where resistance-conferring transgenes are expressed only in MSV-infected cells. However, most known inducible transgene expression systems are hampered by background or “leaky” expression in the absence of the inducer. Here we describe an adaptation of the recently developed INPACT system to express MSV-derived resistance genes in cell culture. Split gene cassette constructs (SGCs) were developed containing three different transgenes in combination with three different promoter sequences. In each SGC, the transgene was split such that it would be translatable only in the presence of an infecting MSV’s replication associated protein. We used a quantitative real-time PCR assay to show that one of these SGCs (pSPLITrepIII-Rb-Ubi) inducibly inhibits MSV replication as efficiently as does a constitutively expressed transgene that has previously proven effective in protecting transgenic maize from MSV. In addition, in our cell-culture based assay pSPLITrep III-Rb-Ubi inhibited replication of diverse MSV strains, and even, albeit to a lesser extent, of a different mastrevirus species. The application of this new technology to MSV resistance in maize could allow a better, more acceptable product.
α-Amylase Assay of Bacillus Subtilis KC 3 : Isolated from Euphorbia Hirta Rhizosphere

Microbial α -amylases with extensive commercial applications in various sectors occupy a quarter of the world enzyme market. Studies were carried out with a bacterial strain producing extracellular α-amylase isolated from rhizospheric soil of Euphorbia hirta. The isolate was gram positive motile rod with terminal spore. It exhibited >98% similarity with the reference strains in the GenBank. The phylogenetic tree constructed on the basis of 16S rRNA gene sequences revealed that it clustered with the closest members of Bacillus subtilis and identified as Bacillus subtilis KC3. Furthermore, the effect of incubation period, temperature, pH and different carbon and nitrogen sources of the medium was optimized. The maximum enzyme production was found after 48h (22.92 U/ml) at 40°C and pH 7. The optimal temperature and pH for enzyme activity were 50°C and 6.5 respectively. Barley starch (27.27 U/ml) was observed to be the best inducer followed by corn starch (24.30 U/ml) and maltose (19.10 U/ml). The addition of glucose to the culture medium greatly reduced the synthesis of α-amylase (5.45 U/ml) which demonstrates that a classical glucose effect is operative in this organism. These properties of Bacillus subtilis KC3, suggest that this is a promising isolate which merits further investigations for potential application in various biotechnological processes.
Algebraic D-modules and Representation Theory of Semisimple Lie Groups

This expository paper represents an introduction to some aspects of the current research in representation theory of semisimple Lie groups. In particular, we discuss the theory of “localization” of modules over the enveloping algebra of a semisimple Lie algebra due to Alexander Beilinson and Joseph Bernstein [1], [2], and the work of Henryk Hecht, Wilfried Schmid, Joseph A. Wolf and the author on the localization of Harish-Chandra modules [7], [8], [13], [17], [18]. These results can be viewed as a vast generalization of the classical theorem of Armand Borel and Andre Weil on geometric realization of irreducible finite-dimensional representations of compact semisimple
Retinal oxygen tension and the electroretinogram during arterial occlusion in the cat.

PURPOSE Retinal oxygen tension (PO2), photoreceptor oxygen consumption (QO2), the local electroretinogram (LERG), and the vitreally recorded electroretinogram (ERG) were evaluated during retinal artery occlusion in the cat. The feasibility of supplying the retina with oxygen during occlusion by ventilation with 100% O2 was evaluated. METHODS Double-barreled oxygen microelectrodes were used to measure intraretinal PO2 and LERGs in anesthetized cats before, during, and after occlusion of a single retinal artery. Outer retinal (photoreceptor) QO2 was determined from retinal PO2 profiles. RESULTS During air breathing, occlusion obliterated the LERG b-wave and reduced the vitreal ERG by the amount expected from the area supplied by the occluded vessel. The PO2 in the entire inner retina was zero, and photoreceptor QO2 was decreased by approximately 25%. Inspiration of 100% O2 restored the b-wave amplitude to approximately 50% of normal and increased the amount of O2 reaching the inner retina. Hyperoxia could not guarantee nonzero PO2 across the entire retina in either darkness or light, but it elevated the average PO2 in the innermost 25% of the retina to more than 20 mm Hg. The b-wave amplitude must have been affected by some factor in addition to local hypoxia, because the amplitude was not correlated with inner retinal PO2 during occlusion, and a normal PO2 did not result in a normal LERG. Effects of 2 to 2.5 hours of occlusion were reversible if 100% O2 inspiration was maintained during most of the occlusion. CONCLUSIONS Ventilation with 100% O2 during occlusion increased the PO2 across most of the retina and partially restored the LERG b-wave, but the tissue near the vitreous was still sometimes anoxic. The illumination status seemed to make little difference. Inspiration of elevated O2 might be beneficial in treating retinal vascular occlusive disease, although it alone cannot completely maintain retinal function.
3-D imaging of general configuration spaceborne bistatic SAR based on compressive sensing

General bistatic synthetic aperture radar SAR (BiSAR) has unequal velocities or/and nonparallel tracks, which is more challenging to process than monostatic and translational invariant configuration. Bistatic SAR has many advantages in three dimensional tomography than classical monostatic, such as no layover and regularly distribution baseline. However, processing bistatic SAR data has a lot of difficulties. Several monostatic algorithms have been modified to solve the problem of general case, but their performance still need improvement. In this paper, three-dimensional BiSAR signal model is derived, and a novel 3-D imaging of general spaceborne Bistatic SAR based on Compressive Sensing is presented, called NCS-CSM (Nonlinear Chirp Scaling-Compressive Sensing Method). The three dimensional tomography experiments validate the effectiveness and accuracy of NCS-CSM.
Hematoma Growth in Oral Anticoagulant Related Intracerebral Hemorrhage

Background and Purpose— Limited data suggest that intracerebral hemorrhage related to oral anticoagulant therapy (OAT ICH) is associated with more hemorrhage expansion and a worse prognosis than spontaneous ICH (SICH). Methods— We examined patients enrolled in the placebo arm of the CHANT study, a prospective randomized trial of a putative neuroprotectant in patients with ICH. All patients had neuroimaging within 6 hours of symptom onset and at 72 hours. Initial ICH volume and hemorrhage expansion were determined by a central reader. Multivariable logistic regression was used to determine factors associated with ICH expansion and mortality at 90 days. Results— Of 303 patients included, 21 (6.9%) had OAT ICH. Baseline median ICH volume was greater in patients with OAT ICH compared to SICH (30.6 versus 14.4 mL, P=0.03). Hemorrhage expansion (defined as >33% increase in ICH volume) occurred in 56% of patients with OAT ICH compared to 26% of SICH (P=0.006). Mortality was substantially higher in OAT ICH (62% versus 17%, P<0.001). In multivariable analysis, time to neuroimaging and oral anticoagulant use were independently associated with hemorrhage expansion, and age, gender, and oral anticoagulant use were independently associated with mortality. Conclusions— These findings confirm that OAT ICH is associated with more hemorrhage expansion and greater mortality than SICH.
Habituation and dishabituation to speech and office noise

The authors examined whether background noise can be habituated to in the laboratory by using memory for prose tasks in 3 experiments. Experiment 1 showed that background speech can be habituated to after 20 min exposure and that meaning and repetition had no effect on the degree of habituation seen. Experiment 2 showed that office noise without speech can also be habituated to. Finally, Experiment 3 showed that a 5-min period of quiet, but not a change in voice, was sufficient to partially restore the disruptive effects of the background noise previously habituated to. These results are interpreted in light of current theories regarding the effects of background noise and habituation; practical implications for office planning are discussed.

Why don't offenders complete treatment? Prisoners’ reasons for non-completion of a cognitive skills programme

Abstract In an evaluation of the Enhanced Thinking Skills (ETS; Cann et al., 2003) programme, reconviction at 1 year was higher for treatment non-completers (i.e. those allocated to treatment who started but did not complete) than for untreated prisoners (i.e. those not allocated to treatment). It may be that non-completion increases risk of reconviction for some offenders, hence efforts should be made to reduce non-completion rates. In designing retention strategies, the views of offenders are important. This study, conducted with adult male prisoners, elicited information from ETS non-completers (n=18) about what interfered with programme completion. For comparison, views on ETS of completers (n=6) were taken. The main themes were: (1) non-completers were motivated to stop offending and motivated for treatment; (2) compared with completers, non-completers saw ETS as less relevant and less well-timed in relation to their current concerns; (3) some non-completers found ETS too demanding, while others found ETS too slow and patronizing; and (4) working in a group was an area of dissatisfaction for non-completers. Limitations are the small sample size, varying reasons for non-completion, and gathering of offenders’ views retrospectively. In future, treatment engagement should be studied prospectively, examining different categories of non-completers, and using larger samples.
