Tweet Sentiment Analyzer: Sentiment Score Estimation Method for Assessing the Value of Opinions in Tweets

Social networking applications are prominent among the internet user communities. Many social media websites are used for sharing the information instantly. Twitter is one of the vibrant social networking websites for sharing small textual information within a short span of time. It is essential to identify the type of information shared on these websites. Sentiment analysis involves the process of analyzing the opinion content present in the text. Millions of tweets are posted in a day about various topics. Twitter sentiment analysis mainly involves the process of identifying the polarity oriented terms mentioned in the tweet. Most of the twitter sentiment analysis works have concentrated on the sentiment polarity identification. Based on the literature, it is observed that, researchers still need to contribute in the area of sentiment score calculation of a tweet. Hence, in this work, sentiment score calculation is carried out with sentiment corpus oriented approach for calculating the score effectively. In addition, the grammatical type of the word used in a tweet, the relationship between the words are properly identified. The tweet tagger, corpus based sentiment score assignment have been distinctively used when compared to other previous works. The experimental results show that the sentimental score based tweet identification resulted in top tweets among the large collection of tweets.
Synovial Hemangioma of the Knee Management and Excellent Outcome 2 Years after Arthroscopic Synovectomy in a 25-year-old Male with a 20-year History

Introduction: Synovial hemangioma is a rare condition with <200 published case reports in world literature and is frequently misdiagnosed, leading to diagnostic delay of many years. This delay is even more significant if the patient comes from a rural background with a dearth of medical facilities in the area. This case had a lag of nearly 20 years from the time of onset of symptoms and the required management which is the maximum reported for any synovial hemangioma since most of them have been found and treated in adolescents. Case Report: We present a case of an atypical synovial hemangioma in a 25-year-old Indian male from a poor socioeconomic background with a delay of 20 years who had both recurrent knee effusions and long-standing knee pain but kept ignoring his symptoms. It was managed by arthroscopic synovectomy. The patient reported to us after 2 years after the surgery with a painless knee and full range of movement. Conclusion: Synovial hemangioma mostly affects the knee joint, showing recurrent bloody effusions without a history of trauma. If there are no intermittent effusions, the diagnosis will be even more difficult. In cases of non-specific symptoms and long-standing knee pain of many years, the diagnosis of a synovial hemangioma should also be considered. In this particular case, magnetic resonance imaging was used to evaluate the patient after the plain radiographs and showed characteristic lace-like or linear patterns. Diagnostic arthroscopy and surgical excision were done in the same sitting, and biopsy was sent to the histopathology laboratory which confirmed our diagnosis. Although this patient had the disease since 20 years and presented late, he had little degeneration of cartilage at the time of arthroscopy. The functional outcome at 2-year follow-up was excellent, and he had no disability, effusion and was pain free.
Practical Grammar-Based NLG from Examples

We present a technique that opens up grammar-based generation to a wider range of practical applications by dramatically reducing the development costs and linguistic expertise that are required. Our method infers the grammatical resources needed for generation from a set of declarative examples that link surface expressions directly to the application's available semantic representations. The same examples further serve to optimize a run-time search strategy that generates the best output that can be found within an application-specific time frame. Our method offers substantially lower development costs than hand-crafted grammars for application-specific NLG, while maintaining high output quality and diversity.
Global chondrocyte gene expression after a single anabolic loading period: Time evolution and re‐inducibility of mechano‐responses

Aim of this study was a genome‐wide identification of mechano‐regulated genes and candidate pathways in human chondrocytes subjected to a single anabolic loading episode and characterization of time evolution and re‐inducibility of the response. Osteochondral constructs consisting of a chondrocyte‐seeded collagen‐scaffold connected to β‐tricalcium‐phosphate were pre‐cultured for 35 days and subjected to dynamic compression (25% strain, 1 Hz, 9 × 10 min over 3 hr) before microarray‐profiling was performed. Proteoglycan synthesis was determined by 35S‐sulfate‐incorporation over 24 hr. Cell viability and hardness of constructs were unaltered by dynamic compression while proteoglycan synthesis was significantly stimulated (1.45‐fold, p = 0.016). Among 115 significantly regulated genes, 114 were up‐regulated, 48 of them ≥ twofold. AP‐1‐relevant transcription factors FOSB and FOS strongly increased in line with elevated ERK1/2‐phosphorylation and rising MAP3K4 expression. Expression of proteoglycan‐synthesizing enzymes CHSY1 and GALNT4 was load‐responsive as were factors associated with the MAPK‐, TGF‐β‐, calcium‐, retinoic‐acid‐, Wnt‐, and Notch‐signaling pathway which were significantly upregulated SOX9, and BMP6 levels rose significantly also after multiple loading episodes at daily intervals even at the 14th cycle with no indication for desensitation. Canonical pSmad2/3 and pSmad1/5/9‐signaling showed no consistent regulation. This study associates novel genes with mechanoregulation in chondrocytes, raising SOX9 protein levels with anabolic loading and suggests that more pathways than so far anticipated apparently work together in a complex network of stimulators and feedback‐regulators. Upregulation of mechanosensitive indicators extending differentially into the resting time provides crucial knowledge to maximize cartilage matrix deposition for the generation of high‐level cartilage replacement tissue.
Risk of invasive cervical cancer among women with, or at risk for, HIV infection

Although invasive cervical cancer (ICC) has been included among the AIDS‐defining conditions since 1993, it remains controversial whether HIV infection increases the risk of developing such neoplasm. In this study, ICC risk was longitudinally investigated among 1,340 HIV‐positive intravenous drug user (IDU), 811 HIV‐negative IDU, and 801 HIV‐positive heterosexual women. These women, aged 15–49 years, were followed up at the Italian HIV Seroconverter Study, at the San Patrignano Community (Rimini, North Italy), and in South‐eastern France (the DMI‐2 study). The number of observed cases of ICC was compared with the expected one, based on ICC incidence rates among women of the same age in the general population of Italy or France, and standardized incidence ratios (SIR) were computed; 9,070 person‐years of observation were accumulated among HIV‐positive women and 2,310 among HIV‐negative ones. Ten cases of ICC were diagnosed among HIV‐positive women (SIR = 12.8): ICC risk was apparently higher among HIV‐positive IDU (SIR = 16.7) than among heterosexual women (SIR = 6.7). No cases of ICC were diagnosed among HIV‐negative IDU women admitted to the San Patrignano Community (0.15 cases were expected). Our findings confirm previous suggestions showing an increased risk of ICC among HIV‐infected women and have important implications at the individual and public health levels. Int. J.

Constrained Efficient Global Optimization of Expensive Black-box Functions

We study the problem of constrained efficient global optimization, where both the objective and constraints are expensive black-box functions that can be learned with Gaussian processes. We propose CONFIG (CONstrained efFIcient Global Optimization), a simple and effective algorithm to solve it. Under certain regularity assumptions, we show that our algorithm enjoys the same cumulative regret bound as that in the unconstrained case and similar cumulative constraint violation upper bounds. For commonly used Matern and Squared Exponential kernels, our bounds are sublinear and allow us to derive a convergence rate to the optimal solution of the original constrained problem. In addition, our method naturally provides a scheme to declare infeasibility when the original black-box optimization problem is infeasible. Numerical experiments on sampled instances from the Gaussian process, artificial numerical problems, and a black-box building controller tuning problem all demonstrate the competitive performance of our algorithm. Compared to the other state-of-the-art methods, our algorithm significantly improves the theoretical guarantees, while achieving competitive empirical performance.
U.S. Department of Veterans Affairs Enterprise Reference Terminology Strategic Overview

The Veterans Health Affairs (VHA) branch of the Department of Veterans Affairs has undertaken an Enterprise Reference Terminology (ERT). VHA, arguably the largest integrated healthcare provider in the United States, has completely computerized virtually all clinical transactions, including physician orders and documentation. The VA is now integrating its clinical records across hundreds of sites of care by means of a Health Data Repository (HDR) project. ERT has been designed to provide a terminology development environment, terminology services, and maintenance services for the clinical and business content in HDR and other VHA applications. Drug, laboratory observations, and clinical document title files have been developed, and the ERT will encompass all HDR domains by 2008. Commercial tools are used to host the VHA's ERT terminology development and server environments. We will select and adopt both open-source and licensable terminology systems to provide ERT content, as well as reuse existing VA-specific terminology content.
Enhanced neuromorphic visual processing by segmented neuron for intelligent vehicle

The neuromorphic visual processing framework mimicking the biological vision system offers an alternative process into applying computer vision in everyday environment. With the growing interest for an effective approach for making detection of vulnerable road users for the purpose of safety enhancement, the proposed neuromorphic visual processing was tested on vulnerable road users such as cyclists on the road. The effectiveness of proposed neuromorphic networks of visual processing is evaluated for the vulnerable road user detection technology via maintaining the successful detection rate of over 95% without complex denoising network. The segmented neuron mixed with the rectifier enhanced the performance via extending the detection range by 33 % as well as saving the denoising process. The post enhancement with deep networks becomes flexible that further applications could be sought from incorporating neuromorphic visual processing. The early implementation demonstrated the advantages of fast and robust neuromorphic vision with either the mobile embedded systems of GPU or FPGA hardware processing, or the portable computer based emulator.
Multivariate Polynomials, Duality, and Structured Matrices

We first review the basic properties of the well known classes of Toeplitz, Hankel, Vandermonde, and other related structured matrices and reexamine their correlation to operations with univariate polynomials. Then we define some natural extensions of such classes of matrices based on their correlation to multivariate polynomials. We describe the correlation in terms of the associated operators of multiplication in the polynomial ring and its dual space, which allows us to generalize these structures to the multivariate case. Multivariate Toeplitz, Hankel, and Vandermonde matrices, Bezoutians, algebraic residues, and relations between them are studied. Finally, we show some applications of this study to rootfinding problems for a system of multivariate polynomial equations, where the dual space, algebraic residues, Bezoutians, and other structured matrices play an important role. The developed techniques enable us to obtain a better insight into the major problems of multivariate polynomial computations and to improve substantially the known techniques of the study of these problems. In particular, we simplify and/or generalize the known reduction of the multivariate polynomial systems to the matrix eigenproblem, the derivation of the Bezout and Bernshtein bounds on the number of the roots, and the construction of multiplication tables. From the algorithmic and computational complexity point, we yield acceleration by one order of magnitude of the known methods for some fundamental problems of solving multivariate polynomial systems of equations.
Definition of Compartment Based Radical Surgery in Uterine Cancer—Part I: Therapeutic Pelvic and Periaortic Lymphadenectomy by Michael Höckel Translated to Robotic Surgery

Objective. To define compartment based therapeutic pelvic and periaortic lymphadenectomy in cervical and endometrial cancer. Compartment based oncologic surgery appears to be favorable for patients in terms of radicality as well as complication rates, and the same appears to be true for robotic surgery. We describe a method of robotically assisted compartment based lymphadenectomy step by step in uterine cancer and demonstrate feasibility data from 35 patients. Methods. Patients with the diagnosis of endometrial (n = 16) or cervical (n = 19) cancer were included. Patients were treated by rTMMR (robotic total mesometrial resection) or rPMMR (robotic peritoneal mesometrial resection) and pelvic or pelvic/periaortic rtLNE (robotic therapeutic lymphadenectomy) with cervical cancer FIGO IB-IIA or endometrial cancer FIGO I-III. Results. No transition to open surgery was necessary. Complication rates were 13% for endometrial cancer and 21% for cervical cancer. Within follow-up time median (22/20) month we noted 1 recurrence of cervical cancer and 2 endometrial cancer recurrences. Conclusions. We conclude that compartment based rtLNE is a feasible and safe technique for the treatment of uterine cancers and is favorable in aspects of radicality and complication rates. It should be analyzed in multicenter studies with extended followup on the basis of the described technique.
Vowel spaces in Plains Cree

This paper presents a pilot study of the acoustic correlates of the Plains Cree vowel system. Naturalistic recordings of speakers of mid-20th-century Plains Cree, including one monolingual speaker, provide an empirical test for the general expectations from phonological descriptions. The results demonstrate that, while the hypothesized short/long vowel pairs do indeed have a strong durational contrast, the majority of vowel pairs are also distinguished by their formants. In all cases, the long vowel occupies a more extreme position in the vowel space. Plains Cree thus appears to show both a quantity and a quality contrast in its vowel pairs. The individual speaker data are then normalized to test whether there is intra-speaker variation in these results, with the results showing variation in the relation between vowels in all three parts of the vowel space.
Main-Memory Management to support Orthogonal Persistence for Java

The main-memory management of an object cache that provides an orthogonally persistent platform for Java is described. Features of the architecture include: two levels of bu ering between the disk and virtual machine, a consistent representation of transient and active objects, an e cient residency checking algorithm in the presence of multiple threads of execution, and well developed object-cache management technology. We present some of the challenges of providing persistence for the Java virtual machine, which may be typical of any attempt at an industrial-strength orthogonally persistent programming system. Some of these might have been avoided by sacri cing persistence independence, but that is far too valuable to sacri ce. We report on some detailed investigations of pinning and cache replacement techniques applicable in this context. The information available for eviction-victim selection is inevitably limited by imprecise information about the state of the machine and the cost of collection. The question is raised whether we can do better than random eviction with real rather than synthetic loads given these limits.

Automatically classifying emails into activities

Email-based activity management systems promise to give users better tools for managing increasing volumes of email, by organizing email according to a user's activities. Current activity management systems do not automatically classify incoming messages by the activity to which they belong, instead relying on simple heuristics (such as message threads), or asking the user to manually classify incoming messages as belonging to an activity. This paper presents several algorithms for automatically recognizing emails as part of an ongoing activity. Our baseline methods are the use of message reply-to threads to determine activity membership and a naïve Bayes classifier. Our SimSubset and SimOverlap algorithms compare the people involved in an activity against the recipients of each incoming message. Our SimContent algorithm uses IRR (a variant of latent semantic indexing) to classify emails into activities using similarity based on message contents. An empirical evaluation shows that each of these methods provide a significant improvement to the baseline methods. In addition, we show that a combined approach that votes the predictions of the individual methods performs better than each individual method alone.
Nonlinear Model Predictive Control With Neural Network Optimization for Autonomous Autorotation of Small Unmanned Helicopters

This paper presents a solution to the autonomous vertical autorotation problem of unmanned helicopters using a novel nonlinear model predictive controller (NMPC) enhanced by a recurrent neural network (RNN) that handles the nonlinear optimization. The controller utilizes an internal, nonlinear autorotation model and is capable of handling input and output constraints that directly map to quality, efficiency and safety requirements. The RNN is employed to achieve real-time operation because it is capable of improving convergence performance, especially when hardware that supports task parallelization is available. This is of major importance when dealing with small unmanned helicopters with limited onboard computational power, where high update rates are required to successfully perform the autorotation maneuver. The proposed NMPC/RNN combination signifies the first use of a nonlinear model for online autorotation trajectory optimization, thus allowing for easier adaptation to other helicopter types without the need for retraining as in the case of machine learning techniques used by the state-of-the-art. An additional novelty of this research concerns the use of an objective function designed to eliminate the risk of fatalities to people on the ground. This is in contrast to previous works where the goal was to save the aircraft and is achieved by appropriately lowering the kinetic energy of the helicopter during the last phase of its descent. The paper discusses in detail the general design of the NMPC/RNN, before going into the specifics regarding the derivation, implementation and integration of the autonomous autorotation controller itself. The performance of the latter is validated using extensive simulation results.
Roles of cytosol and cytoplasmic particles in nuclear envelope assembly and sperm pronuclear formation in cell-free preparations from amphibian eggs

A cell-free cytoplasmic preparation from activated Rana pipiens eggs could induce in demembranated Xenopus laevis sperm nuclei morphological changes similar to those seen during pronuclear formation in intact eggs. The condensed sperm chromatin underwent an initial rapid, but limited, dispersion. A nuclear envelope formed around the dispersed chromatin and the nuclei enlarged. The subcellular distribution of the components required for these changes was examined by separating the preparations into soluble (cytosol) and particulate fractions by centrifugation at 150,000 g for 2 h. Sperm chromatin was incubated with the cytosol or with the particulate material after it had been resuspended in either the cytosol, heat-treated (60 or 100 degrees C) cytosol or buffer. We found that the limited dispersion of chromatin occurred in each of these ooplasmic fractions, but not in the buffer alone. Nuclear envelope assembly required the presence of both untreated cytosol and particulate material. Ultrastructural examination of the sperm chromatin during incubation in the preparations showed that membrane vesicles of approximately 200 nm in diameter, found in the particulate fraction, flattened and fused together to contribute the membranous components of the nuclear envelope. The enlargement of the sperm nuclei occurred only after the nuclear envelope formed. The pronuclei formed in the cell-free preparations were able to incorporate [3H]dTTP into DNA. This incorporation was inhibited by aphidicolin, suggesting that the DNA synthesis by the pronuclei was dependent on DNA polymerase-alpha. When sperm chromatin was incubated greater than 3 h, the chromatin of the pronuclei often recondensed to form structures resembling mitotic chromosomes within the nuclear envelope. Therefore, it appeared that these ooplasmic preparations could induce, in vitro, nuclear changes resembling those seen during the first cell cycle in the zygote.
Integrating software process models and design rationales

We describe an approach which allows us to acquire, represent and manage fine-grained causal dependencies between products. These dependencies are basically derived automatically from a software process model. By representing causal dependencies and their rationales, the traceability of the software development processes is improved. Our dependency-based system is able to support users in reacting to changes. Thereby, the costs of software development can be reduced. Based on the theoretical work, the CoMo-Kit System was implemented consisting of a modeling component and a process engine. The use of the system is illustrated.
