An Automatic Approach to Feature Extraction

The pervasive diffusion of social networks as common way to communicate and share information is becoming a valuable resource for analysts and decision makers. Reviews are used every day by common people or by companies who need to make decisions. It is evident that even the opinion monitoring is essential for listening to and taking advantage of the conversations of possible customers in a decision making process. Opinion Mining is a way to analyse opinions related to specific topics: products, services, tourist locations, etc. In this paper we propose an automatic approach to the extraction of feature terms, applying our experience in the semantic analysis of textual resources to Opinion Mining task and performing a contextualisation by means of semantic categorisation, and by a set of qualities associated to the sense expressed by adjectives and adverbs.
Organic Integrity Test (OIT) as an Empirical Guide in the Treatment of Schizophrenia

The study of a single case, though less conclusive, sometimes heralds methodological advance. Hopefully, other investigators will be able to replicate the findings on a large number of subjects. This report, based on the case history of Bob R. , describes in detail how the Organic Integrity Test (OIT) may be used as a daily therapeutic index in the treatment of schizophrenia.
Pallidal Stimulation for Dystonia

OBJECTIVE:High-frequency deep brain stimulation (DBS) of the globus pallidus internus (GPi) is a new and promising treatment option for severe dystonia. Yet only few studies have been published to date regarding this treatment. We present the results of DBS of the GPi in 17 patients with severe dystonia of different causes. METHODS:In our study, we included 10 patients with primary generalized dystonia, six patients with secondary generalized dystonia, and one patient with a severe dystonic cervical tremor. In all patients, DBS electrodes were implanted bilaterally within the GPi. Mean follow-up time was 36 months (range, 12–66 mo). Preoperative and postoperative evaluations (at least annually) were performed using the Burk-Fahn-Marsden scale. RESULTS:The best improvement was achieved in patients with DYT1-positive dystonia. Patients with DYT1-negative generalized dystonia showed inhomogeneous results. There was no significant change in patients with tardive dystonia. One case of Hallervorden-Spatz disease improved dramatically within the first 2 years. The improvement in the cervical dystonic tremor was disappointing, however. Three years after DBS implantation, we found a secondary worsening of symptoms in one patient with a DYT1-positive dystonia and in the patient with Hallervorden-Spatz disease. CONCLUSION:DBS of the GPi is a new and promising treatment option for dystonia. Secondary worsening may limit this therapy.
' s response to reviews Title : Barriers encountered during enrollment in an internet-mediated randomized controlled trial

Background Online technology is a promising resource for conducting clinical research. While the internet may improve a study’s reach, as well as the efficiency of data collection, it may also introduce a number of challenges for participants and investigators. The objective of this research was to determine the challenges that potential participants faced during the enrollment phase of a randomized controlled intervention trial of Stepping Up to Health, an internet-mediated walking program that utilized a multi-step online enrollment process. Methods We conducted a quantitative content analysis of 623 help tickets logged in a participant management database during the enrollment phase of a clinical trial investigating the effect of an automated internet-mediated walking intervention. Qualitative coding was performed by two trained coders, and 10% of the sample was coded by both coders to determine inter-coder reliability. Quantitative analyses included standard descriptive statistics on ticket characteristics and theme frequency, and a Poisson regression analysis identified characteristics of potential participants who reported more frequent problems during enrollment. Results In total, 880 potential participants visited the study website and 80% completed the enrollment screening. Of the potential participants who visited the study website, 38% had help tickets logged in the participant management database. The total number of help tickets associated with individual potential participants ranged from 0 to 7 (M=.71). Overall, 46% of help tickets were initiated by email and 54% were initiated by phone. The most common help ticket theme was issues related to the study process (48%). The next most prominent theme was discussion related

Transplantation of neural stem cells into explants of Rat inner ear

Damage and loss of hair cells in the inner ear is the most frequent cause of hearing loss and balance disorders. Mammalian hair cells do not regenerate in the conventional ways. To regenerate the hair cell in the mammalian inner ear we transplanted neural stem cells into explants of rat inner ear. The stem cells integrated successfully into the sensory epithelium of the vestibular organs, but not into the organ of Corti. This method is useful to investigate efficient ways to transplant stem cells into the inner ear.
Identification of approximately duplicate material records in ERP systems

ABSTRACT The quality of master data is crucial for the accurate functioning of the various modules of an enterprise resource planning (ERP) system. This study addresses specific data problems arising from the generation of approximately duplicate material records in ERP databases. Such problems are mainly due to the firm’s lack of unique and global identifiers for the material records, and to the arbitrary assignment of alternative names for the same material by various users. Traditional duplicate detection methods are ineffective in identifying such approximately duplicate material records because these methods typically rely on string comparisons of each field. To address this problem, a machine learning-based framework is developed to recognise semantic similarity between strings and to further identify and reunify approximately duplicate material records – a process referred to as de-duplication in this article. First, the keywords of the material records are extracted to form vectors of discriminating words. Second, a machine learning method using a probabilistic neural network is applied to determine the semantic similarity between these material records. The approach was evaluated using data from a real case study. The test results indicate that the proposed method outperforms traditional algorithms in identifying approximately duplicate material records.
Ultra precise position estimation of servomotor using analog quadrature encoders

This paper describes the ultra precise position estimation of a servomotor using a sinusoidal encoder based on Arcsine Interpolation Method for the cost reduction of circuit design. The amplitude and offset errors of the sinusoidal encoder output signals, from encoder itself and analog signal processing procedures, are effectively compensated and on-line tuned by utilizing a low cost programmable differential amplifier without any special expensive equipments. To theoretically evaluate the practical resolution of this system, the relationship between the amplitude of ADC input signal errors and the anticipated resolution is also dealt with. The performance of the proposed method is verified by comparing it with speed control characteristics of the servomotor driving system using a digital incremental 50,000ppr encoder in the experiments.
Conscious Access to Suppressed Threatening Information Is Modulated by Working Memory

Previous research has demonstrated that emotional information processing can be modulated by what is being held in working memory (WM). Here, we showed that such content-based WM effects can occur even when the emotional information is suppressed from conscious awareness. Using the delayed-match-to-sample paradigm in conjunction with continuous flash suppression, we found that suppressed threatening (fearful and angry) faces emerged from suppression faster when they matched the emotional valence of WM contents than when they did not. This effect cannot be explained by perceptual priming, as it disappeared when the faces were only passively viewed and not held in WM. Crucially, such an effect is highly specific to threatening faces but not to happy or neutral faces. Our findings together suggest that WM can modulate nonconscious emotion processing, which highlights the functional association between nonconsciously triggered emotional processes and conscious emotion representation.
Biological Control Products for Aflatoxin Prevention in Italy: Commercial Field Evaluation of Atoxigenic Aspergillus flavus Active Ingredients

Since 2003, non-compliant aflatoxin concentrations have been detected in maize produced in Italy. The most successful worldwide experiments in aflatoxin prevention resulted from distribution of atoxigenic strains of Aspergillus flavus to displace aflatoxin-producers during crop development. The displacement results in lower aflatoxin concentrations in harvested grain. The current study evaluated in field performances of two atoxigenic strains of A. flavus endemic to Italy in artificially inoculated maize ears and in naturally contaminated maize. Co-inoculation of atoxigenic strains with aflatoxin producers resulted in highly significant reductions in aflatoxin concentrations (>90%) in both years only with atoxigenic strain A2085. The average percent reduction in aflatoxin B1 concentration in naturally contaminated maize fields was 92.3%, without significant differences in fumonisins between treated and control maize. The vegetative compatibility group of A2085 was the most frequently recovered A. flavus in both treated and control plots (average 61.9% and 53.5% of the A. flavus, respectively). A2085 was therefore selected as an active ingredient for biocontrol products and deposited under provisions of the Budapest Treaty in the Belgian Co-Ordinated Collections of Micro-Organisms (BCCM/MUCL) collection (accession MUCL54911). Further work on development of A2085 as a tool for preventing aflatoxin contamination in maize produced in Italy is ongoing with the commercial product named AF-X1™.
WHAT IS THE MEANING OF THRESHOLD IN LASER INJURY EXPERIMENTS? IMPLICATIONS FOR HUMAN EXPOSURE LIMITS

The derivations of human exposure limits for laser radiation rely heavily upon experimental ocular injury studies. The limits are derived by committees of ophthalmic experts through a review of all available threshold data and an understanding of mechanisms of laser/tissue interaction. A major point of discussion in this derivation process relates to the level of uncertainty of the threshold of injury. An indication of the level of uncertainty relates to the slope of the transformed dose-response curve, or the “probit plot” of the data. The most cited point on the probit plot is the exposure that represents a 50% probability of injury: the ED-50. This value is frequently referred to as the “threshold,” even though some experimental damage points exist below this “threshold. ” An analysis of any number of example data sets reveals that the slope in most experiments cannot be explained by biological variation alone. The optical, thermophysical, and biological factors influencing the probit plot are critically analyzed to provide guidance for deriving exposure limits. By theoretically modeling an experiment, small errors in focus are shown to produce a substantial change in the ED-50 and the slope of the probit plot.
Forecast strategy using an adaptive fuzzy classification algorithm for load

Forecast is applied in many fields. The determination of system signals, states or parameters of technical and not technical processes allows the solution of higher level tasks, for instance the optimization of complex systems or the generation of decisions. Basic methods of prediction are signal models, analytical, symbolic, cognitive models and state-space models [1], [2], [3], [4], [5]. The problem definition and the process character influence essentially the choice of the model type. The current state of forecast methods is demonstrated in figure 1.
Measurement of the horny layer turnover after staining with dansyl chloride: description of a new method.

A simple non-radioactive technique is described. The corneal layers were stained with 5% dansyl chloride ointment during 24-48 h of occlusion. The number of newly formed corneal layers were counted on sections from punch biopsies obtained at various intervals after the staining. The rate of formation is given as layers formed per 24 hours. The technique makes it possible to detect an increase in the turnover rate when it is more than 15-32% above normal. The biological material can also be utilized for comparative studies utilizing biochemical and histological methods. The average rate of formation was 1.15+-0.09 (S.E.M.) layers per 24 hours in a group of 10 subjects.
Prevalence of Alzheimer's disease and other dementias in an elderly urban population

We studied the prevalence of different types of dementia in an elderly population in Stockholm, Sweden, in relation to age, sex, and education. The study confirmed Alzheimer's disease (AD) as the most frequent type of dementia and the positive association of dementias with age, even in the most advanced ages. In contrast to previously reported data, we found the same proportion of AD and vascular dementia in the different age strata, and no sex differences regarding the prevalence of different dementia types. Finally, less educated people had a higher prevalence of all dementias, due essentially to a higher prevalence of alcoholic dementia and unspecified type of dementia. The prevalence of AD was similar across different levels of education.
Coexistent Primary Open-Angle Glaucoma and Cataract: Interim Analysis of a Trabecular Micro-Bypass Stent and Concurrent Cataract Surgery

Purpose To evaluate the safety and efficacy of the iStent Trabecular Micro-bypass Stent in patients undergoing concurrent cataract and glaucoma surgery. Methods Prospective, 24-month, uncontrolled, multicenter, multicountry evaluation of 58 patients with uncontrolled primary open-angle glaucoma (including pseudoexfoliation and pigmentary) and cataract. Patients underwent clear cornea phacoemulsification followed by ab interno gonioscopically guided implantation of the iStent. Of the 48 per protocol population, 42 patients completed 12 months of the 24-month study, and their data are included in this interim analysis. Results At baseline, mean (±SD) intraocular pressure (IOP) was 21.7±3.98 mmHg. At 12 months, mean IOP was reduced to 17.4±2.99 mmHg, a mean IOP reduction of 4.4±4.54 mmHg (p<0.001, 18.3%). At baseline, patients were taking a mean 1.6±0.8 medications. By 12 months, the mean number of medications was reduced to 0.4±0.62 (p<0.001). Half the patients achieved an IOP ≤18 mmHg and were able to discontinue hypotensive medication by the 12-month visit. The most commonly reported device-related adverse events were the appearance of stent lumen obstruction (7 eyes) and stent malposition (6 eyes). None of the adverse events were deemed serious. Conclusions In patients undergoing concurrent cataract and glaucoma surgery, the iStent was safe and efficacious for the reduction of IOP and medication therapy.
Microbial Community and Population Dynamics Analysis of Anaerobic Fermentation of Vegetable Waste under Different pH

The advantage bacterium group of acidogenic and methanogenic processes by PCR-denaturing gradient gel electrophoresis (DGGE) under different pH values(4.1~4.3 and 5.9~6.1) was studied . 16S rDNA of bacteria and methanogenic archaea amplified with two universal primers (341F-GC /109F-GC and 518R). PCR amplicons were separated by denaturing gradient gel electrophoresis (DGGE) using the DGGE Decode system. Parts of the separated DNA were sequenced after purification from DGGE gel. The sequences of several 16S rDNA DGGE fragments were determined and some possible bacteria were confirmed in comparison in GeneBank (NCBI). The results showed that the acidogenic phase of fruits and vegetables during the fermentation process display different type: ethanol-type and butyrate-type fermentation and the predominant bacterium act differently. The predominant organism groups of methanogenic processes within the reactor performed differently, too. These results indicated that the change in the product formation was mainly caused by the change of the dominant microbial populations under different pH conditions.
Does Board Experience Matter? Evidence from Foreign Direct Investment

This study contributes to the growing literatures on the importance of board expertise to their provision of counsel for management. By demonstrating that when announcing overseas investments, how a firm alleviates its liabilities of foreignness by board members possessing relevant experiences, the present work addresses the long-standing issue of what renders board the most effective. Drawing on expertise literature, we exam the efficacy of both director specific and heterogeneous experience, assessed by foreign market entry mode and targeted host country. The empirical results yield support for favorable impacts of both types of director experience. This finding corroborates the transition of board’s role from “passively” ratifying executive proposals, as predicted by agency theory, to “actively” instructing executives, as argued by resource dependence theory. The resource provision function of a board is further supported by greater benefits of director experience in situations of limited firm resources, assessed by executives’ associated experience. Finally, we find that directors who have operated independently from the CEO but without relevant experience cannot have significant influence on investment outcome. Our research result contributes to corporate governance research predominated by agency theory for the past decades, which presumes director independence as the foremost prerequisite for board effectiveness.
Estimating Tote Drop Height & Impact Acceleration from a Transportation Recorder

Healthcare products are often shipped from a distribution center to a retail store in plastic totes. Previous research on plastic tote distribution at the Healthcare Packaging Consortium has suggested that the use of bubble wrap and air pillows at tote bottom and top, respectively, reduces impact. In addition to the use of bubble wrap and air pillows, monitoring tote handling would also have the potential to reduce distribution damages. A transportation recorder was used to aid this study. Equations were developed from the drop test data to estimate drop height and impact acceleration at tote bottom from impact acceleration obtained from the recorder.
A revision of cercocarpus

The original collection of the genus Cercocarpus was made near the City of Mexico by Humboldt and Bonpland and was described and illustrated carefully by Kunth (1823). He assigned it to the section Sanguisorbeae Juss. of the family Rosaceae on the basis of the tubular persistent calyx, the absence of petals, the single one-celled ovary and the fruit an achene. The type species is C. fothergiUoides H. B. K. Moci~o and Sess$ also collected this plant early and named it Bertolonia guieroides; this name was published first in the Prodromus (De Candolle 1825) as a synonym of C. fothergilloides H. B. K. In the summer of 1820, Dr. Edwin P. James joined Long's First Expedition to the Rocky Mountains and collected a Cercoearpus which was described by Dr. John Torrey (1828) and assigned by him to C. fothergilloides H. B. K. Dr. C. S. Rafinesque (1832) recognized it as being a new species and named it C. montanus. Thomas Nuttall (ex Hook. & Am. 1838) collected the same plant "on the Platte River" and named it C. parvi[olius, the name by which this particular entity was known until Dr. P. A. Rydberg (1913) recognized the name C. montanus as valid. Other early collections were made by Douglas in about 1831 and by Nuttall in about 1835, both in California, of the entity variously known as C. betuloides Nutt. , C. betulaefolius Nutt. , and C. parvifolius Nutt. var. glaber S. Wars. A number of new species and varieties were collected from Mexico and the western United States, but a careful revision of the genus as a whole was not attempted until Dr. Camillo Karl Schneider (1905a, 1905b) studied it from material borrowed from the Missouri Botanical Garden. The most thoroughgoing revision has been that of Dr. P. A. Rydberg (1913). Since several of the supposed species he described have been considered by later authors as not worthy of specific rank, it has seemed worthwhile to investigate the genus on the basis of the extensive new collections now available. The genus was placed in the subtribe Cercocarpeae of the tribe Dryadeae (Torr. & Gray 1840). Later the subtribe was raised to the status of a tribe and Adenostoma, Coleogyne, Purshia, and Chamaebatia were included under it with Cereocarpus (Focke in Engler & Prantl 1888). Later the tribe Cercocarpeae was narrowed to contain only Cercocarpus (Rydberg 1913). In general the members of the genus Cercocarpus are montane xerophytes. Their habitat, together with their extremely hard wood, has earned for them the name "mountain mahogany," which was applied first by the Mormon pioneers of Utah to C. ledifolius, according to the label on a specimen collected by Col. Fremont (in 1854, NY). The long silky tails of their fruits have caused them to be called "plume-trees. " Most of them are shrubs, but many are trees; however, after fires even the tree-like forms often become shrubby.
The slab heating furnace temperature presetting model and optimization

In order to solve the problem that the mathematics model's computation speed of the furnace is slow in operation and the temperature difference between the calculated temperature distribution and the real furnace temperature distribution is quite different, the presetting point model in the furnace control system is improved in this paper. The mathematics model of furnace temperature is consisted of mathematical model of billet heat transfer and presetting temperature of furnace. The furnace temperature is optimized to save the energy consumption of the furnace by genetic algorithm. A new method for calculating the fitness function is introduced. The constraint of the temperature difference between the preheating zone and the heating zone is added in the constraint condition. The simulation results show that the optimized furnace temperature can meet the requirements of slab rolling and the actual furnace temperature distribution. Meanwhile, the optimized furnace temperature is lower than the furnace temperature before optimization, which achieves the goal of energy conservation.
