Domain Independent Model for Product Attribute Extraction from User Reviews using Wikipedia

The world of E-commerce is expanding, posing a large arena of products, their descriptions, customer and professional reviews that are pertinent to them. Most of the product attribute extraction techniques in literature work on structured descriptions using several text analysis tools. However, attributes in these descriptions are limited compared to those in customer reviews of a product, where users discuss deeper and more specific attributes. In this paper, we propose a novel supervised domain independent model for product attribute extraction from user reviews. The user generated content contains unstructured and semi-structured text where conventional language grammar dependent tools like parts-of-speech taggers, named entity recognizers, parsers do not perform at expected levels. We used Wikipedia and Web to identify product attributes from customer reviews and achieved F1score of 0.73.
Image reconstruction based on combination of modified CoSaMP and orthogonal wavelets

Compressive sensing is a signal processing technique for efficiently acquiring and reconstructing the signals by finding solutions to underdetermined linear systems. Non-linear optimization algorithms are used to solve underdetermined linear system. Greedy algorithms are widely used due to their low complexity than that of non-linear optimization algorithms. The problem with the Greedy algorithms is that some algorithms reduces reconstruction time but quality of reconstruction is affected while some require more reconstruction time with high quality of reconstruction. This is serious issue for the large size images. In this paper we have worked on CoSaMP algorithm and by modifying it we have reduced reconstruction time to reconstruct the sparse image with high quality of reconstruction which solves the above mention problem. Experimentation is performed on Modified CoSaMP using orthogonal filters like db4, Haar and coif3 for different size of the images and results in terms of PSNR (peak signal to noise ratio), SSIM (Structural similarity index measurement) and runtime have been calculated and compared with OMP, ROMP, OLS and CoSaMP.
Pseudoelastic mesh–moving using a general scenario of the selective mesh stiffening

The selective mesh stiffening in this study changes the stiffness of the element based on both the element area and shape. It includes the stiffening in the previous studies as a specific case, and leads to a general scenario in the pseudoelastic mesh–moving. This scenario gives better mesh quality in the mesh-moving of a rectangular domain with a structure consisting of a square and a fin undergoes large rotations. This is because the shear deformation of the element is adaptively considered.
Synthesis and Characterization of Polyvinylpyrrolidone(PVP) Nanofibrous Thin Films

In the present work we have synthesised PVP composite nanofiber by using the electrospinning technique. The development, and morphology of the readied nanofibers were analysed by SEM. Arrangement of ultra-fine consistent smooth fibers with diameter across in the scope of 64-116 nm and length up to a few microns was seen in the case of PVP composite nanofibers. Experimental investigation was performed by electrospinning of PVP considering 6grams dissolved in 40ml Di-MethylFormamide(DMF). The process parameters considered were voltage of 20kV, flow rate 0.5ml/hr, needle dimension 21 gauge and tip-to-collector distance 100 mm. It was found that concentration of polymer is a critical factor in controlling the beads formation and fiber diameters although applied voltage and Spinneret to-collector distance also influenced the fiber diameter.
Albumin-Coated Bioactive Suture for Cell Transplantation

Cell therapy holds the promise for a novel modality in the surgical toolkit; however, delivery of cells into damaged soft tissues constitutes a challenge. The authors hypothesized that growing stem cells on the surface of absorbable sutures in vitro and then implanting them via stitching would be a suitable delivery route for cell therapy. Fibronectin, poly-L-lysine, and albumin coatings were used to increase attachment of human and rat bone-marrow-derived mesenchymal stem cells (BMSC) to polyfilament absorbable sutures in vitro. Fluorescence microscopy was performed to localize the cells on the suture. After 48 hours of incubation, the albumin-coated sutures had the highest cell number, and after 168 hours cell number reached confluency. In the in vivo experiments, a 10-mm incision was made on the triceps surae muscle of male Wistar rats and rat BMSC coated sutures were placed into the muscle. Two days after the implantation, cells were seen on the surface of the sutures as well as in the surrounding muscle tissue. Long-term results at 5 weeks showed that transplanted cells survived and the sutures were partly absorbed. In conclusion, coating absorbable sutures with proteins, especially serum albumin, improves attachment and proliferation of cells, and only 48 hours in culture is enough to cover the sutures sufficiently. Using these stitches in vivo resulted in short-term and long-term survival of cells. As a result, albumin-coated suture can be a vehicle for stem cell therapy in soft tissues such as muscle, tendon, or peripheral nerves.
Kernel Least-Squares Models Using Updates of the Pseudoinverse

Sparse nonlinear classification and regression models in reproducing kernel Hilbert spaces (RKHSs) are considered. The use of Mercer kernels and the square loss function gives rise to an overdetermined linear least-squares problem in the corresponding RKHS. When we apply a greedy forward selection scheme, the least-squares problem may be solved by an order-recursive update of the pseudoinverse in each iteration step. The computational time is linear with respect to the number of the selected training samples.
Magnetic Actuation of Multifunctional Nanorobotic Platforms to Induce Cancer Cell Death

Single‐bath potentiostatic‐pulsed electrodeposition enables the synthesis of bicomponent (i.e., gold and nickel–nickel oxide) multi‐segmented magnetic nanowires that, with extraordinarily low cytotoxicity, are ideal three‐functional medical nanoplatforms because they can transport two types of functional molecules and be magnetically actuated for both controlled targeting and inducing cancer cell death. Alternated segments of Au and Ni–Ni oxide are selected to confer a magnetic character to the nanowires, prevent their dissolution in the cellular medium, and permit selective bio‐functionalization with thiol and porphyrin test molecules. The bi‐functionalized nanowires internalized in HeLa cancer cells, similar to other organelles, move inside the living cells. Applying the rotating magnetic fields cause them vibrate and increase their motion, although high viscosity and the presence of the cytoskeleton and other protein matrices preclude their rotation inside cells. Since no magneto‐mechanical destruction of the HeLa cells occurs on their membranes, organelles, or cytoskeletons programmed cancer cell death is likely induced by the vibration and translation of the nanowires, not by mechanical destruction.
Applications of Machine Learni g to Information Access

The recent explosion of on-line information has given rise to a number of query-based search engines (e.g., Alta Vista) and manually constructed topic hierarchies (e.g., Yuhoo! ). But with the current rate of growth in the amount of available information, query results grow incomprehensibly large and manual classification in topic hierarchies creates an immense information bottleneck. Therefore, these tools are rapidly becoming inadequate for addressing users’ information needs. We address these problems with a system for topical information space navigation that combines the querybased and taxonomic systems. Our system is built within a unifying probabilistic framework, thereby harnessing the expressive power of this representation while also providing understandable semantics. We are developing a system to automatically create dynamic hierarchical document categorizations based on the full-text of networked articles. Employing clustering technologies, such as AutoClass (Cheeseman et al. 19SS), we can organize document collections at a more “topical” level. This is similar in flavor to the Scatter/Gather system (Cutting et al. 1992), but allows for a variety of disparate, networked information sources to be dynamically accessed. Moreover, this approach is then extended to automatically organize collections of documents into a topic hierarchy, thereby providing a greater contextual organization to the document collection. A prototype of this system has already been implemented as part of the Stanford Digital Libraries testbed (Sahami, Yusufali, & Baldonado 1997). improvement is derived from the fact that these simpler decisions at each level of the hierarchy can be made by considering only the presence (or absence) of a small number of features (words) in the document. The selection of relevant words uses a novel information theoretic algorithm we have developed for feature selection (Koller & Sahami 1996). Moreover, the utilization of feature selection to reduce the input space enables us to employ more expressive classification models. To this end, we have developed an efficient method for inducing Bayesian classifiers which do not assume conditional independence of inputs (Sahami 1996), since such an independence assumption can be unrealistic for modelling words in text documents. The integration of the hierarchical clustering and classification methods will allow large amounts of information to be organized and presented to a user in a comprehensible way, one which is tailored to his or her own particular needs. By alleviating the information bottleneck, we hope to provide users with a solution to the problems of the information access on the Internet.
Using Ensemble Learning and Association Rules to Help Car Buyers Make Informed Choices

Cars are an essential part of our everyday life. Nowadays we have a wide plethora of cars produced by a number of companies in all segments. The buyer has to consider a lot of factors while buying a car which makes the whole process a lot more difficult. So in this paper we have developed a method of ensemble learning to aid people in making the decision. Bagging, boosting and voting ensemble learning have been used to improve the precision rate i.e. accuracy of classification. Also we have performed class association rules to see if it performs better than collaborative filtering for suggesting item to the user.
Optimizing Time and Power Allocation for Four-Node Wireless Broadcasting Channel with Relay

In this paper, we investigate the optimal power and time allocation for a wireless relay network, called BCFR (Broadcasting Channel with Fixed Relay), where the relay node is limited by the half-duplex operation. Introducing a relay in two-node broadcasting channel for a node which has a link of bad quality or requires higher transmission rate enlarges the rate region with well-designed power and time allocation. Also, BCFR is a common component of many relay networks,in which either orthogonal or non- orthogonal transmission can be adopted at the information source node. In particular, for the non-orthogonal transmission, the layered transmission with superposition coding is applied at the source node. By deriving the optimal power and time-fraction allocation at each node of BCFR, we show that the non-orthogonal structure enhances the capacity region and achieves higher log-sum capacity than the orthogonal transmission.
The strength of traditional and self-pierced riveted joints

The objective of this study is to compare the strength of riveted joints fabricated by traditional riveting (with pre-drilled holes) and self-piercing riveting (SPR) for different types of joints. Riveted joints were produced using steel and aluminum alloy rivets and two types of sheet material: 235JR steel sheet and EN AW 6060 aluminum alloy sheet with the following dimensions: length l = 100 ± 1 mm, width b = 50 ± 1 mm and thickness g = 2 mm. For all tested types of riveted joints (pre-drilled and SPR), 5 sets of joints were fabricated, each set containing 6 samples. The sets of joints differed with respect to the number of rivets (1, 2, 3, 4 and 6 rivets), joint type (single-, threeand four-riveted joints) and lap length. For all tested joints, the highest load capacity was obtained for self-pierced riveted joints, while the lowest – for pre-drilled joints with aluminum alloy rivets. In addition, it was found that the shear strength of self-pierced riveted joints is higher than that of aluminum and steel blind rivets.
Efficiency Measurement of Housing Sector ; Using DEA Model

Production economics is a fundamental concept in economic theory and housing production is no exception. The present research provides a critical review of the housing industry efficiency in Iran. Data Envelopment Analysis (DEA) is used to evaluate housing industry performance in different states based on the relevant data collected from Statistical Centres of Iran during 2006-2009. The research found that only 37 percent of the states operate technically efficient and the average efficiency score obtained by all the states is 0.94. Most of the technically efficient states had the opportunity to employ illegally migrated workers of neighbouring countries in building construction activities using the advantages of lower level of payments and less commitment to the worker's insurance regulations in the country. Providing subsidy assistance to the disadvantaged states and stimulating legal employment of building workers will supplement government to improve efficiencies in the sector and finding a solution to the current housing problem.
MicL, a new σE-dependent sRNA, combats envelope stress by repressing synthesis of Lpp, the major outer membrane lipoprotein

In enteric bacteria, the transcription factor σE maintains membrane homeostasis by inducing the synthesis of membrane repair proteins as well as two small regulatory RNAs (sRNAs) that down-regulate membrane porin synthesis. Here, Storz and colleagues identify a third σE-dependent sRNA, MicL, transcribed from the cutC gene coding sequence. MicL represses the outer membrane lipoprotein Lpp and is responsible for the copper sensitivity phenotype previously associated with cutC loss. This discovery is critical to understanding the networks that control outer membrane homeostasis in response to stress.
A generic dynamic programming Matlab function

This paper introduces a generic dynamic programming function for Matlab. This function solves discretetime optimal-control problems using Bellman's dynamic programming algorithm. The function is implemented such that the user only needs to provide the objective function and the model equations. The function includes several options for solving optimal-control problems. The model equations can include several state variables and input variables. Furthermore, the model equations can be time-variant and include time-variant state and input constraints. The syntax of the function is explained using two examples. The first is the well-known Lotka-Volterra fishery problem and the second is a parallel hybrid-electric vehicle optimization problem.
A 12-month follow-up of hypopigmentation after laser hair removal

Abstract Introduction: Laser hair removal is becoming an increasingly popular alternative to traditional methods such as shaving, waxing, among other methods. Semiconductor diode lasers are considered the most efficient light sources available and are especially well suited for clinical applications including hair reduction. The effectiveness of laser hair reduction depends on many variables, including the skin type of the patient. Material and Methods: A patient with Fitzpatrick Skin Type IV was submitted to laser hair removal of the arms with a high-power diode laser system with long pulses with a wavelength of 800 nm, a fluence of 40 J/cm2 and a pulse width of 20 ms. A 12-month follow-up assessment was performed and included photography and questionnaire. Results: Hypopigmentation was observed after a single laser hair removal section. After 6 months with the area totally covered, a gradual suntan with a sun screen lotion with an SPF of 15 was prescribed by the dermatologist. After 12 months of the initial treatment, a complete recovery of the hypopigmentation was achieved. Conclusion: Although a safe procedure, lasers for hair removal may be associated with adverse side effects including undesired pigment alterations. Before starting a laser hair removal treatment, patients seeking the eradication of hair should be informed that temporary, and possibly permanent, pigmentary changes may occur.
The Impact of the Introduction of the U.K. Minimum Wage on the Employment Probabilities of Low-Wage Workers

This paper uses longitudinal data from three contrasting data sets (matched Labor Force Surveys, the British Household Panel Survey, and matched New Earnings Surveys) to estimate the impact of the introduction of the U.K. minimum wage (in April 1999) on the probability of subsequent employment among those whose wages would have needed to be raised to comply with the minimum. A difference-in-differences estimator is used, based on position in the wage distribution. No significant adverse employment effects are found for any of the four demographic groups considered (adult and youth, men and women) or in any of the three data sets used. (JEL: J38, J23)
Clinical and economic evaluation of a Case Management Service for patients with back pain

AIM To evaluate the clinical-effectiveness and resource use associated with Case Management Services in a UK private sector DESIGN: An observational cohort study based on prospective data collection of patient reported outcome measures and data collection from an existing administrative health database. SETTING A United Kingdom (UK) private healthcare provider PARTICIPANTS: Consecutive referrals into the Case Management Service over a three-month period. INTERVENTIONS Participants were managed within the Case Management Service in accordance with usual pathways. MAIN OUTCOME MEASURES Outcome measures included EQ-5D-5L and PSFS. Measurements were taken at baseline, and repeated at the point at which the client's case was closed. The CARE measure examined patient reported experience. Cost Consequence analysis was completed using existing data for the same period of time in two separate years: 2014, two years after CMS implementation, and 2011, prior Case Management Service development RESULTS: There was a statistically significant improvement in quality of life (EQ-5D-5L p < 0.0001; EQ-VAS p < 0.001) and functional ability (p < 0.001) following the Physiotherapy Case Management. The CARE measure showed high levels of patient satisfaction with 96% of clients rating their individual case manager as good to excellent. The cost consequences analysis showed a cost reduction in therapy resource utilisation by £252 842 (from £10 772 875 to £10 520 034). CONCLUSIONS The Case Management Service showed the provision to be providing significant improvement in quality of life and functional outcomes within efficient use of resources, and service users are highly satisfied with their experience.
IgG4-Related Disease: Dataset of 235 Consecutive Patients

AbstractImmunoglobulin G4-related disease (IgG4-RD) is a recently discovered systemic condition, in which various organ manifestations are linked by a similar histological appearance. Our knowledge of this condition is still fragmented, as most studies have examined only a few dozen patients or focused on a particular organ manifestation. This study was conducted to learn the demography and patient characteristics of IgG4-RD using a large cohort. A total of 235 consecutive patients with IgG4-RD, diagnosed in 8 general hospitals in the same medical district, were identified by searching the institutions’ radiology database. Inclusion criteria were histology-proven IgG4-RD according to the Pathology Consensus Statement and/or definitive type 1 autoimmune pancreatitis meeting the International Consensus Diagnostic Criteria. Clinical notes and images of selected patients were retrospectively reviewed. All patients were adults (M/F = 4/1). The median age was 67 years (range 35–86). Nine tenths were diagnosed in their 50s to 70s. Among 486 manifestations identified in total, the most common was pancreatitis diagnosed in 142 patients (60%), followed by sialadenitis (34%), tubulointerstitial nephritis (23%), dacryoadenitis (23%), and periaortitis (20%). The majority of patients (95%) had at least 1 of the 5 most common manifestations. Male and female patients differed in their organ manifestations (periaortitis more common in males and sialodacryoadenitis more common in females). Serum IgG4 (normal ⩽135 mg/dL) was elevated to >135 mg/dL in 208 patients (88%) and >270 mg/dL in 167 (71%). The IgG4 value was significantly higher in patients with multiorgan involvement than in those with a single manifestation (median 629 mg/dL vs 299 mg/dL, P < 0.01). Of 218 patients, for whom both IgG4 and IgG values were available, the IgG4/IgG ratio was raised to >10% in 194 (89%). Corticosteroids were effective, but the relapse rate was estimated to be 24% in the study period (median 37 months). During the follow-up, 15 malignant diseases were diagnosed in 13 patients (6%). This figure is similar to the incidence (12.9 cancers) expected from the Japanese nationwide study for cancer epidemiology (standardized incidence ratio 1.16). In conclusion, this reliable dataset could improve the characterization of IgG4-RD, particularly its unique demography and the frequency of each organ manifestation.
An object-oriented approach to federated databases

Work on object-oriented database and programming technology has resulted in a number of important and powerful concepts and mechanisms, not only essential for modeling and implementing next generation database systems, but also useful for designing and constructing a network of distributed, autonomous databases (e.g. a federated database architecture). By applying the concept of 'object' to database level, many of the associated mechanisms can be adopted and extended naturally, so as to accommodate the desired sharing and exchange of information among databases. The authors describe such an 'object-oriented' approach towards federating a collection of decentralized, heterogeneous databases, and examines several issues that must be addressed within such an environment. <<ETX>>
