Make It Possible: Multilingual Sentiment Analysis without Much Prior Knowledge

Sentiment analysis is a hard problem, while multilingual sentiment analysis is even harder due to the different expression styles in different languages. Although many methods for multilingual sentiment analysis have been developed in the open literature, most of them suffer from two major problems. The first is their excessive dependence on external tools or resources (e.g., Machine translation systems or bilingual dictionaries), which may not be readily obtained, especially for minority languages, The second is conflictive sentiments, i.e., The sentiment polarity of some parts of a text is inconsistent with its overall sentiment polarity. It is observed that in a product or service review there usually exist a few sentences which play a more important role in determining its sentiment polarity, as compared to others. Therefore, differentiating key sentences from trivial ones may be helpful to improve sentiment analysis. Inspired by this observation in this paper we propose a novel framework to estimate the sentiment polarity of reviews by virtue of opinion lexica and key sentences automatically extracted from unlabelled data. This framework cannot only overcome the problem of excessive dependence on external resources, but also is able to capture the overall sentiment polarity of reviews. Experimental results on realistic review datasets demonstrate that the proposed framework is effective and competitive with the representative baselines.
Optically active erbium-doped waveguides fabricated using a single-sol-gel-deposition technique

We present the results of optical-characterization experiments conducted on optically active erbium-doped waveguides. Using selected characterization results presented in this paper and a simple analysis, the device operation is evaluated. Each of the core and the cladding layers were individually fabricated using a single sol-gel deposition. These are, to the best of our knowledge, the first optically active waveguides to be fabricated in such a way. Characterization results include gain, fluorescence-lifetime, waveguide-loss, polarization-dependent-loss (PDL), and erbium-absorption measurements. Relative gains of over 1 dB/spl middot/cm/sup -1/ were measured. Fluorescence lifetimes of the /sup 4/I/sub 13/2/ /spl rarr/ /sup 4/I/sub 15/2/ transition as high as 5.6 ms were observed. Waveguide losses as low as 0.13 dB/spl middot/cm/sup -1/ were measured.
Design and analysis of metastable-hardened and soft-error tolerant high-performance, low-power flip-flops

In this paper, detailed analysis is given on the design of metastable-hardened and soft-error tolerant flip-flops while maintaining the basic characteristics of low-power and high-performance. We also propose two new flip-flop designs: pre-discharge soft-error tolerant flip-flop (PDFF-SE) and sense-amplifier transmission-gate soft-error tolerant flip-flop (SATG-SE). Following our main design approach, both PDFF-SE and SATG-SE use a cross-coupled inverter on the critical path in the master-stage to achieve good metastability while generating differential signals to facilitate the usage of the Quatro cell in the slave-stage to protect against soft-errors. PDFF-SE is designed to achieve very high performance with good metastability while SATG-SE is a low-power design also with good metastability. We also introduce two new design metrics, namely the metastability-delay-product (MDP) and the metastability-power-delay-product (MPDP), to analyze the design tradeoffs between metastability, power, and performance. Simulation results in 65nm CMOS technology have shown that both proposed designs achieve significant reduction in MDP and MPDP when compared to other flip-flop architectures analyzed in this work. Monte Carlo simulation results also show that these flip-flops are very robust and reliable against process variations and mismatches.
Recurrent stroke predictors differ in medically treated patients with pathogenic vs other PFOs

Objective: To examine predictors of stroke recurrence in patients with a high vs a low likelihood of having an incidental patent foramen ovale (PFO) as defined by the Risk of Paradoxical Embolism (RoPE) score. Methods: Patients in the RoPE database with cryptogenic stroke (CS) and PFO were classified as having a probable PFO-related stroke (RoPE score of >6, n = 647) and others (RoPE score of ≤6 points, n = 677). We tested 15 clinical, 5 radiologic, and 3 echocardiographic variables for associations with stroke recurrence using Cox survival models with component database as a stratification factor. An interaction with RoPE score was checked for the variables that were significant. Results: Follow-up was available for 92%, 79%, and 57% at 1, 2, and 3 years. Overall, a higher recurrence risk was associated with an index TIA. For all other predictors, effects were significantly different in the 2 RoPE score categories. For the low RoPE score group, but not the high RoPE score group, older age and antiplatelet (vs warfarin) treatment predicted recurrence. Conversely, echocardiographic features (septal hypermobility and a small shunt) and a prior (clinical) stroke/TIA were significant predictors in the high but not low RoPE score group. Conclusion: Predictors of recurrence differ when PFO relatedness is classified by the RoPE score, suggesting that patients with CS and PFO form a heterogeneous group with different stroke mechanisms. Echocardiographic features were only associated with recurrence in the high RoPE score group.
Association of simvastatin and hyperlipidemia with periodontal status and bone metabolism markers.

BACKGROUND The objective of this study is to determine whether simvastatin consumption and hyperlipidemia are associated with a worse periodontal condition and specific bone activity biomarkers. METHODS This cross-sectional and analytic study includes 73 patients divided into three groups: 1) simvastatin-treated patients with hyperlipidemia (n = 29); 2) patients with hyperlipidemia treated by diet alone (n = 28); and 3) normolipidemic patients (controls, n = 16). The periodontal clinical variables of all participants were gathered, a blood sample was drawn from each to determine the lipid profile (total cholesterol, triglycerides, low-density lipoprotein, and high-density lipoprotein), serum levels of acute-phase reactants (C-reactive protein), erythrocyte sedimentation rate, and bone metabolism markers (osteoprotegerin [OPG], osteocalcin, procollagen type I N-terminal propeptide, and C-terminal telopeptide of type I collagen). RESULTS The mean ESR was higher in the diet-treated patients with hyperlipidemia than in the normolipidemic controls (P = 0.04). Serum OPG concentrations were significantly higher in the simvastatin-treated patients with hyperlipidemia than in the diet-treated patients with hyperlipidemia (P = 0.05). Multivariable linear regression analysis adjusted for age, sex, tobacco, and alcohol revealed that, compared with the normolipidemic patients, the simvastatin-treated patients with hyperlipidemia showed a mean reduction of 0.8 mm (95% confidence interval = -1.5 to 0.0, P = 0.05) in clinical attachment loss. CONCLUSIONS Within the limits of this study, the findings suggest that the intake of simvastatin is associated with increasing serum OPG concentrations, and this could have a protective effect against bone breakdown and periodontal attachment loss. The baseline systemic inflammatory state of patients with hyperlipidemia is indicated by their increased erythrocyte sedimentation rate.
Improved Implementation for Finding Text Similarities in Large Sets of Data - Notebook for PAN at CLEF 2011

In this article we describe a new algorithm method for the detection of plagiarism. The method removes numerous limitations of our older method, which has been used as part of a complex information system for the detection of plagiarism. The method has been tested using multiple corpora mainly in Slovak language. With the PAN-09 and PAN-10 corpora it was of great advantage that we could compare our results with the results of other methods. The very good initial results gave us motivation to implement multiple algorithm and parameter improvements.
Rehabilitation Complexity Scale: Italian translation and transcultural validation

Abstract Purpose: The aim of the present study was translation, cultural adaption and validation of the extended version 12 of the Rehabilitation Complexity Scale (RCS-E) in a sample of patients with stroke and total hip replacement. Method: The cross-cultural validation required RCS-E forward–backward translation, revision by an expert committee and its application in an Intensive Rehabilitation setting through a retrospective collection of data from clinical records. The evaluation of the psychometric properties was carried out by analyzing the correlations between RCS-E score and other measures (Functional Independence Measure, Braden, Morse, Cumulative Illness Rating Scale) and the assessment of reliability in terms of reproducibility (inter-observer agreement) and repeatability (intra-observer agreement). Results: The backward and forward processes of translation of the scale did not create problems of interpretation of terms. Some adaptation was required for the items nursing (N), medical care (M) and therapeutic intensity (TI) due to differences on the national health system structure. The Italian version of the scale proved to be valid, reliable with high reproducibility and repeatability. Conclusions: The Italian version RCS-E has been successfully validated, showing good psychometric properties, which partly reproduce the results obtained for the original version. However, some assumption was made for some items thus preventing possible comparison with other countries. Implications for Rehabilitation Admittance at an Intensive Rehabilitation care setting in Italy requires to evaluate the complexity of rehabilitation needs. The Rehabilitation Complexity Scale (RCS-E) has proved to be reliable for assessing clinical complexity and consequently for planning rehabilitation needs. The Italian version of RCS-E has been successfully validated, showing good psychometric properties, which reproduce the results obtained for the original version. The items included in the therapy intensity subscale do not fit the Italian health system rules for intensity of rehabilitation care and needs adaptation.
CALCIUM AND MAGNESIUM IN DRINKING WATER AND RISK OF DEATH FROM PROSTATE CANCER

The possible association between the increased risk of prostate cancer and the levels of calcium and magnesium in drinking water from municipal supplies was investigated in a matched cancer case-control study in Taiwan. All eligible prostate-cancer deaths (682 cases) of Taiwan residents from 1987 through 1993 were compared with deaths from other causes (682 controls). The levels of calcium and magnesium in the drinking water of these residents were also determined. Data on calcium and magnesium levels in drinking water throughout Taiwan were obtained from the Taiwan Water Supply Corporation (TWSC). The control group consisted of people who died from other causes, and the controls were pair-matched to the cases by year of birth and death. The adjusted odds ratios for prostate cancer death for those with higher magnesium levels in their drinking water, as compared to the lowest tertile, were 0.73 (95% CI = 0.51? 1.03) and 0.64 (95% CI = 0.43? 0.96), respectively. The adjusted odd ratios for the relationship between calcium levels in drinking water and prostate cancer were not statistically significant. The results of the present study show that there may be a significant protective effect of magnesium intake from drinking water and other dietary sources against the risk of prostate cancer development.
A Framework for Improved Automated Test and Costwise Life-Cycle Support

Migration of the Department of Defense (DoD) toward net-centric warfare makes information transfer and sharing available to various application users. The concepts of net-centric warfare applied to autonomic logistics and streamlined maintenance implies increased operational effectiveness with lower life-cycle costs and reduced manning. A unified diagnostic framework that defines standards for data representation and services for reusability of support data across all levels of maintenance enhances this technology. It would also eliminates an environment that manifests as a continued expanding of dedicated test equipment, incomprehensible and unusable data, and ever increasing manpower and training requirements. This paper presents use cases and example applications that demonstrate a realization of greater interoperability and weapon/repair system effectiveness through automated data processing and knowledge sharing enabled by standardized data streams and information services. The maintenance process begins with available onboard data sources, followed by repair processes through all maintenance levels, and lessons learned from life-cycle tracking to affect positive change in emerging and evolving systems. The emerging framework for automated test systems is examined as a vehicle to sustain and advance future support systems.
POSTER: AdHoneyDroid -- Capture Malicious Android Advertisements

In this paper we explore the problem of collecting malicious smartphone advertisements. Most smartphone app contains advertisements and also suffers from vulnerable advertisement libraries. Malicious advertisements exploit the ad library vulnerability and attack victim smartphones. Similar to the traditional honeypots, we need an effective way to capture malicious ads. In this paper, we provide our approach named AdHoneyDroid. We build a crawler to gather apps on the android marketplaces and manually collect ad libraries and their vulnerabilities. Then AdHoneyDroid executes the apps and detects malicious advertisements. In our approach, we adopt the idea of API sandbox and TaintDroid to detect the attack event. We store the malicious advertisements in a database for future analysis. Malicious ads can help security analysts have a better understanding of current mobile attacks and also disclose the attack payloads.
Class 3 semaphorins negatively regulate dermal lymphatic network formation

ABSTRACT The development of a patterned lymphatic vascular network is essential for proper lymphatic functions during organ development and homeostasis. Here we report that class 3 semaphorins (SEMA3s), SEMA3F and SEMA3G negatively regulate lymphatic endothelial cell (LEC) growth and sprouting to control dermal lymphatic network formation. Neuropilin2 (NRP2) functions as a receptor for SEMA3F and SEMA3G, as well as vascular endothelial growth factor C (VEGFC). In culture, Both SEMA3F and SEMA3G inhibit VEGFC-mediated sprouting and proliferation of human dermal LECs. In the developing mouse skin, Sema3f is expressed in the epidermis and Sema3g expression is restricted to arteries, whereas their receptor Nrp2 is preferentially expressed by lymphatic vessels. Both Sema3f;Sema3g double mutants and Nrp2 mutants exhibit increased LEC growth in the skin. In contrast, Sema3f;Sema3g double mutants display increased lymphatic branching, while Nrp2 mutants exhibit reduced lymphatic branching. A targeted mutation in PlexinA1 or PlexinA2, signal transducers forming a receptor complex with NRP2 for SEMA3s, exhibits an increase in LEC growth and lymphatic branching as observed in Sema3f;Sema3g double mutants. Our results provide the first evidence that SEMA3F and SEMA3G function as a negative regulator for dermal lymphangiogenesis in vivo. The reciprocal phenotype in lymphatic branching between Sema3f;Sema3g double mutants and Nrp2 mutants suggest a complex NRP2 function that regulates LEC behavior both positively and negatively, through a binding with VEGFC or SEMA3s.
A privacy-preserving e-participation framework allowing citizen opinion analysis

In e-democracy, e-participation represents a key component, as it is the way to adapt government decisions to the real expectations of citizens. The availability of information-communication technologies represents the basis for the implementation of concrete plans of citizens' participation to the government of the community. However, there is a non trivial trade-off to manage, between security and privacy needs and opinion analysis opportunities. Indeed, whereas we have to guarantee that the action of citizens is kept anonymous, relating opinions to information about people allows the government management to coherently orient the executive action. In this paper, we present a solution of the above trade-off, by proposing a framework relying on existing social networks and working through cryptographic protocols able to ensure citizens' anonymity yet enabling opinion analysis. A careful security analysis and the addressing of the main implementation issues make the proposal ready to a secure and feasible adoption in real-life contexts.
An evaluation of Georgia's agriculture in the classroom program

This study sought to determine the effectiveness of GeorgiaGs Agriculture in the Classroom Program. The study was conducted using an experimental posttest only control group design. Sixteen classes of second grade students and twelve classes of fourth grade students participated in the study. A total of 598 subjects were included. An instrument consisting of multiple choice exams was designed for each grade level. The length and difficulty level of the instrument were set by experts in the field of elementary education. The instruments were piloted tested and adjusted accordingly. The curriculum was taught to the treatment group during a six weeks period. At the completion, both the control and treatment group were given the exams. Results indicated that the program was effective in teaching agricultural concepts whether the groups were in rural or city settings, or when grouped by ability or randomly distributed. No significant differences were found between scores of second graders whose teachers were raised on a farm and those whose teachers were not. Significant differences occurred between control and experimental groups when all the teachers had little or no agriculture experience. In recent years, agricultural educators have stressed the need for a populace who are better informed about agriculture. According to the National Research Council (1988), approximately two percent of the nation's population live on a farm. This contrasts with 30% in 1920 and 15% in 1950. Most of today's elementary school children are at least two generations away from first hand knowledge of agriculture (Farm Bureau Federation, 1983). A Texas study of the needs teachers have for implementing programs of agricultural literacy revealed that almost all of the fourth grade teachers surveyed had an inaccurate perception of agriculture (Terry, Herring, & Larke, 1990). Studies in Kansas (Horn & Vining, 1986) and Virginia (Oliver, 1985) indicated a lack of basic knowledge about agriculture among elementary school students. A conclusion of the National Research Council's study of agricultural education in the United States (1988) was: "Most Americans know very little about agriculture, its social and economic significance in the United States, and particularly, its link to human environmental quality. "(p.9) The study recommended that "All students should receive at least some systematic instruction about agriculture beginning in kindergarten and first grade and continuing through twelfth grade" (p.10).
Population Density and Phenology of Tetranychus urticae (Acari: Tetranychidae) in Hop is Linked to the Timing of Sulfur Applications

ABSTRACT The twospotted spider mite, Tetranychus urticae Koch, is a worldwide pest of numerous agronomic and horticultural plants. Sulfur fungicides are known to induce outbreaks of this pest on several crops, although mechanisms associated with sulfur-induced mite outbreaks are largely unknown. Studies were conducted during 2007–2009 in Oregon and Washington hop yards to evaluate the effect of timing of sulfur applications on T. urticae and key predators. In both regions, applications of sulfur made relatively late in the growing season (mid-June to mid-July) were associated with the greatest exacerbation of spider mite outbreaks, particularly in the upper canopy of the crop. The severity of mite outbreaks was closely associated with sulfur applications made during a relatively narrow time period coincident with the early exponential phase of spider mite increase and rapid host growth. A nonlinear model relating mean cumulative mite days during the time of sulfur sprays to the percent increase in total cumulative mite days (standardized to a nontreated plot) explained 58% of the variability observed in increased spider mite severity related to sulfur spray timing. Spatial patterns of spider mites in the Oregon plots indicated similar dispersal of motile stages of spider mites among leaves treated with sulfur versus nontreated leaves; however, in two of three years, eggs were less aggregated on leaves of sulfur-treated plants, pointing to enhanced dispersal. Apart from one experiment in Washington, relatively few predatory mites were observed during the course of these studies, and sulfur-induced mite outbreaks generally occurred irrespective of predatory mite abundance. Collectively, these studies indicate sulfur induces mite outbreaks through direct or indirect effects on T. urticae, mostly independent of predatory mite abundance or toxicity to these predators. Avoidance of exacerbation of spider mite outbreaks by sulfur sprays was achieved by carefully timing applications to periods of low spider mite abundance and slower host development, which is generally early to mid-spring for hop.
Is neurogenesis reparative after status epilepticus?

Neurogenesis persists in the hippocampal dentate gyrus of mammals, including human and nonhuman primates, throughout life (Altman and Das, 1965; Cameron et al., 1993; Kuhn et al., 1996; Eriksson et al., 1998; Gould et al., 1999; Kornack and Rakic, 2001). Neural stemlike cells reside in the subgranular zone (SGZ) at the border of the hilus and DGC layer (Seri et al., 2001; Filippov et al., 2003), where they generate neuroblasts that migrate into the layer and differentiate into granule neurons (Cameron et al., 1993; Kuhn et al., 1996). Adult-born dentate granule cells (DGCs) send axonal projections to appropriate targets (Stanfield and Trice, 1988; Markakis and Gage, 1999; van Praag et al., 2002) and acquire electrophysiological characteristics of mature DGCs (van Praag et al., 2002; Wadiche et al., 2005; Ge et al., 2006). Although the precise function is unknown, evidence implicates DGC neurogenesis in certain forms of hippocampus-dependent learning and memory (reviewed in Doetsch and Hen [2005]).
Diversity encouraged learning of unsupervised LSTM ensemble for neural activity video prediction

Being able to predict the neural signal in the near future from the current and previous observations has the potential to enable real-time responsive brain stimulation to suppress seizures. We have investigated how to use an auto-encoder model consisting of LSTM cells for such prediction. Recog- nizing that there exist multiple activity pattern clusters, we have further explored to train an ensemble of LSTM mod- els so that each model can specialize in modeling certain neural activities, without explicitly clustering the training data. We train the ensemble using an ensemble-awareness loss, which jointly solves the model assignment problem and the error minimization problem. During training, for each training sequence, only the model that has the lowest recon- struction and prediction error is updated. Intrinsically such a loss function enables each LTSM model to be adapted to a subset of the training sequences that share similar dynamic behavior. We demonstrate this can be trained in an end- to-end manner and achieve significant accuracy in neural activity prediction.
