The imaging analysis of asynchronous bistatic SAR with parallel tracks

The imaging of bistatic SAR with asynchronous transceiver positions is studied in this paper. First of all, the geometry of the asynchronous transceiver model is constructed, and the approximation model of the echo from the bistatic SAR is obtained based on the analysis of the instantaneous transceiver distance. Asynchronous transceiver positions will lead to non-uniform SAR data. This paper first analyzes the method for transforming the asynchronous bistatic model into a monostatic variable motion model. Then with the non-uniform FFT, it resolves the non-uniform sampling problems induced by nonconstant velocities. The simulation experiments show that the bistatic SAR images have good quality, which verifies the validity of the method presented in this paper.
Beyond basic emotions: expressive virtual actors with social attitudes

The purpose of this work is to evaluate the contribution of audio-visual prosody to the perception of complex mental states of virtual actors. We propose that global audio-visual prosodic contours - i.e. melody, rhythm and head movements over the utterance - constitute discriminant features for both the generation and recognition of social attitudes. The hypothesis is tested on an acted corpus of social attitudes in virtual actors and evaluation is done using objective measures and perceptual tests.
FaceTag: Integrating Bottom-up and Top-down Classification

FaceTag is a working prototype of a semantic collaborative tagging tool conceived for bookmarking information architecture resources. It aims to show how the widespread homogeneous and flat keywords' space created by users while tagging can be effectively mixed with a richer faceted classification scheme to improve the “information scent” and “berrypicking” capabilities of the system. The additional semantic structure is aggregated both implicitly observing user behaviour and explicitly introducing a compelling user experience that facilitates the end-user creation of relationships between tags. To evaluate the real benefits introduced by this approach, preliminary user research on the initial prototype is outlined. Extensive evaluation and results will be discussed in a future paper.
Management of stage Ia 1 squamous cervical cancer and the importance of excision margins : a retrospective study of long-term outcome after 25 years of follow-up

RESULTS: We identified 111 women: 19 (17.1%) in group A; 29 (26.1%) in group B; and 63 (56.8%) in group C. Women in group A were older (median, 40 years vs 35 years; P1⁄4 .0001) with higher rate of endocervical margin involvement (89.5 vs 48.1%, P1⁄4 .007) than in group B. The women had been followed for a total of 960 womanyears with median follow-up of 398 weeks (quartiles: 258,612). Women with clear margins in the initial excision were more likely to
Improving trace cache effectiveness with branch promotion and trace packing

The increasing widths of superscalar processors are placing greater demands upon the fetch mechanism. The trace cache meets these demands by placing logically contiguous instructions in physically contiguous storage. As a result, the trace cache delivers instructions at a high rate by supplying multiple fetch blocks each cycle. In this paper we examine two techniques to improve the number of instructions delivered each cycle by the trace cache. The first technique, branch promotion, dynamically converts strongly biased branches into branches with static predictions. Because these promoted branches require no dynamic prediction, the branch predictor suffers less from the negative effects of interference. Branch promotion unlocks the potential of the second technique: trace packing. With trace packing, trace segments are packed with as many instructions as will fit, without regard to naturally occurring fetch block boundaries. With both techniques, the effective fetch rate of the trace cache jumps up 17% over a trace cache which implements neither on a machine where the execution engine has a very aggressive memory disambiguator; the performance of a machine using branch promotion and trace packing is on average 11% higher than a machine using neither technique.
A Comparison of Surgical Techniques Used in Dynamic Reanimation of the Paralyzed Face

Objectives: To compare the outcomes of three surgical techniques used in the rehabilitation of the paralyzed face. Study Design: Retrospective study. Setting: University-based tertiary referral center. Patients: Between 1976 and 2000, rehabilitative facial nerve surgery was performed on 70 adult patients with varying underlying diseases. Intervention: Three methods of facial nerve rehabilitative surgery were performed: end-to-end anastomosis, cable nerve graft interposition, and classic faciohypoglossal transposition. Main Outcome Measures: The House-Brackmann grade was scored at 6, 12, 24, and 36 months by the two senior authors. A favorable outcome was defined as House-Brackmann Grade ≤ III. Other parameters recorded were repair technique, age, nerve rerouting, whether the repair was immediate or delayed, and the anatomic position of the nerve defect in relation to the geniculate ganglion. Results: Data were available on 66 patients (94%), of whom 13 had an end-to-end anastomosis, 25 a cable nerve graft interposition, and 28 a classic faciohypoglossal transposition. At 24 months, a House-Brackmann Grade ≤ III was achieved in 84.6% of those who underwent end-to-end anastomosis, 56.0% of those who underwent cable nerve graft interposition, and 25.0% of those who underwent classical faciohypoglossal transposition. End-to-end anastomosis and cable nerve graft interposition were superior to classic faciohypoglossal transposition (log-rank test, p = 0.0013). Twenty-five percent of all cases demonstrated improvement in House-Brackmann grade after 24 months. Increasing age at the time of repair was associated with a poorer outcome (p = 0.03 on logistic regression). Conclusion: End-to-end anastomosis confers the best facial function, followed by cable nerve graft interposition and then classic faciohypoglossal transposition. Contrary to some previous opinions, improvement in facial function can still occur 2 years after surgical repair, particularly with classic faciohypoglossal transposition.
Bayesian Based Comment Spam Defending Tool

Spam messes up user’s inbox, consumes network resources and spread worms and viruses. Spam is flooding of unsolicited, unwanted e mail. Spam in blogs is called blog spam or comment spam.It is done by posting comments or flooding spams to the services such as blogs, forums,news,email archives and guestbooks. Blog spams generally appears on guestbooks or comment pages where spammers fill a comment box with spam words. In addition to wasting user’s time with unwanted comments, spam also consumes a lot of bandwidth. In this paper, we propose a software tool to prevent such blog spams by using Bayesian Algorithm based technique. It is derived from Bayes’ Theorem. It gives an output which has a probability that any comment is spam, given that it has certain words in it. With using our past entries and a comment entry , this value is obtained and compared with a threshold value to find if it exceeds the threshold value or not. By using this cocept, we developed a software tool to block comment spam. The experimental results show that the Bayesian based tool is working well. This paper has the major findings and their significance of blog spam filter.
A partial flexibility model for vehicle following algorithm

Vehicle following system is a branch of ITS (Intelligent Transportation System). The tacking accuracy is a vital evaluation criterion of the vehicle following system. This paper proposes a partial flexibility model for the vehicle following algorithm to promote the accuracy. We suppose that the follower vehicle is connected to the leader vehicle with a virtual flexible bar with two rigid joints. As the leader vehicle turns from straight line status, the part of the virtual bar which is the closest to leader vehicle bends, while the other parts of the virtual bar are still straight. As a result, the virtual flexible bar fits the trajectory of the leader vehicle and the joint on the follower vehicle forces the follower to go along the trajectory. In this system, we just need to detect the positions of leader vehicle by the sensors which are mounted on the follower. At last, a series of simulations verify that the proposed model has improved the accuracy of vehicle following.
One micrometer resolution NMR microscopy.

We obtained a magnetic resonance image of 1 microm resolution and 75 microm(3) voxel volume for a phantom filled with hydrocarbon oil within an hour at 14.1 T. For this work, a specially designed probe with a high sensitivity RF coil and gradient coils generating over 1000 G/cm was built. The optimal pulse sequence was analyzed in consideration of the bandwidth, diffusion coefficients, and T(1) and T(2) relaxations of the medium. The system was applied to the in vivo imaging of a geranium leaf stem to get the images of 2 microm resolution and 200 microm(3) voxel volume.
Induction of noncatalytic TrkB neurotrophin receptors during axonal sprouting in the adult hippocampus

Brain-derived neurotrophic factor (BDNF) and its signal transducing receptor, the TrkB tyrosine protein kinase, are expressed at high levels in the hippocampus of the adult brain, suggesting a role for BDNF mechanisms in neuronal plasticity. To test this hypothesis, we used defined lesions of perforant path and fimbria-fornix, two major hippocampal afferents, to remove synapses on dendrites of dentate gyrus granule cells and pyramidal cells of Ammon's horn and induce synaptic rearrangements. These combined lesions remove afferent connections from entorhinal cortex and septum and produce massive sprouting of axons of the commissural/associational pathways into the molecular layer of the hippocampal dentate gyrus. At days 1, 3, and 6, the lesions decreased BDNF mRNA expression ipsilaterally to approximately 50% of control, with complete recovery at 14 d. The lesions did not alter trkB mRNA levels in neuronal layers of the hippocampus; however, they resulted in a pronounced induction of trkB mRNA expression in hippocampal non- neuronal cells 6–14 d after lesioning. The induction corresponded in time and place to the synaptic reorganization in the lesioned hippocampus. The mRNA species newly induced by the lesions corresponded to those transcripts encoding the noncatalytic TrkB receptor isoform that lacks the cytoplasmic protein kinase domain. Expression of mRNAs coding for neurotrophin-3 and the TrkC tyrosine protein kinase were not altered by the lesions. The findings suggest that truncated noncatalytic TrkB molecules expressed on the surface of glial cells play an important role in plasticity of the adult brain, possibly regulating the concentration of bioactive neurotrophins or the responsiveness of neurotrophin receptors. Alternatively, they may play a role in presenting neurotrophin molecules to growing axons.
Enhancing data quality by cleaning inconsistent big RDF data

We address the problem of dealing with inconsistencies in fusion of big data sources using Resource Description Framework (RDF) and ontologies. We propose a scalable approach ensuring data quality for query answering over big RDF data in a distributed way on a Spark ecosystem. In so doing, the cleaning inconsistent big RDF data approach is built on the following steps (1) modeling consistency rules to detect the inconsistency triples even if it is implicitly hidden including inference and inconsistent rules (2) detecting inconsistency through rule evaluation based on Apache Spark framework to discover the minimally sub-set of inconsistent triples (3) cleaning the inconsistency through finding the best repair for consistent query answering.
CS 224 N Project : Automatic Comment Summarization

It is very common today for websites to allow readers to comment on articles posted on the Internet. These comment threads usually contain interesting opinions and give a good indication of the average reader’s sentiment. However, readers often post off-topic comments or post without reading all of the existing comments. This means that comments can be redundant or uninformative and that the sheer quantity of comments will quickly grow to an unmanageable size. To address these issues, we developed comment set summarization systems. A comment summarizer takes a comment set and automatically produces a summary that is both indicative of the discussion and brief. We experimented with the following summarization approaches:
DYSTROPHIA CORNEAE PARENCHYMATOSA CONGENITA A CLINICAL, MORPHOLOGICAL AND HISTOCHEMICAL EXAMINATION

Congenital opacities of the cornea have been known for a long time. Franceschetti and Babel (1945) tried to classify the different types and found that they could be divided into two main groups. Of these groups one comprises malformative types of corneal opacitites. The second one is of a degenerative type. This can be transmitted as recessive or dominant characteristics, but the clinical picture is the same. I t has a certain resemblance to other forms of heredo-familiar corneal dystrophies of which Groenouw’s types are those that are most frequently reported. These types, however, rarely begin before the age of 5 years and the clouding gradually increases in density and extent, while the congenital forms are usually more static and show only slight tendency to progress. They are characterized by the presence of diffuse or punctate opacities of the stroma of both corneas. The dominant form is very rare and only a few families are reported (Komoto 1909, Rutherfurd 1931, Fisher and Alcona 1936, Turpin and al. 1939). This family last mentioned is later followed up by Desvignes and Vigo ( 1955). Irregular dominance or sex-linked inheritance is discussed by FranCois (1961) in 5 members of 4 generations of a family suffering from congenital parenchymatous dystrophy of the cornea. The condition is often associated with cataract or constitutional stigmata. The recessive form, which is the commoner, is not accompanied by other ocular anomalies. A greater number of cases of the recessive form of inborn opacity of the cornea have been reported, but not all of them, when more closely studied, belonged to this parenchymatous form. The purpose of this paper is to give a supplement to the cases already reported of the dominant form. I t describes a family of 34 persons of 4 generations, of which 11 of the members had congenital corneal opacities. The condition was not associated with other abnormalities. In 2 of the members a keratoplasty was done, with following histological and histochemical examinations of the excised tissue. In the litterature I have found only one
Update on gene and stem cell therapy approaches for spinal muscular atrophy

Introduction: Spinal muscular atrophy (SMA) is the leading genetic cause of pediatric death to which at present there is no effective therapeutic. The genetic defect is well characterized as a mutation in exon 7 of the survival of motor neuron (SMN) gene. The current gene therapy approach focuses on two main methodologies, the replacement of SMN1 or augmentation of SMN2 readthrough. The most promising of the current work focuses on the delivery of SMN via AAV9 vectors via intravenous delivery. Areas covered: In the review the authors examine the current research in the field of stem cell and gene therapy approaches for SMA. Also focusing on delivery methods, timing of administration and general caveats that must be considered with translational work for SMA. Expert opinion: Gene therapy currently offers the most promising avenue of research for a successful therapeutic for SMA. There are many important practical and ethical considerations which must be carefully considered when dealing with clinical trial in infants such as the invasiveness of the surgery, the correct patient cohort and the potential risks.
ONTS: “Optima” News Translation System

We propose a real-time machine translation system that allows users to select a news category and to translate the related live news articles from Arabic, Czech, Danish, Farsi, French, German, Italian, Polish, Portuguese, Spanish and Turkish into English. The Moses-based system was optimised for the news domain and differs from other available systems in four ways: (1) News items are automatically categorised on the source side, before translation; (2) Named entity translation is optimised by recognising and extracting them on the source side and by re-inserting their translation in the target language, making use of a separate entity repository; (3) News titles are translated with a separate translation system which is optimised for the specific style of news titles; (4) The system was optimised for speed in order to cope with the large volume of daily news articles.
DELLA Proteins and Their Interacting RING Finger Proteins Repress Gibberellin Responses by Binding to the Promoters of a Subset of Gibberellin-Responsive Genes in Arabidopsis[C][W]

This work shows that DELLA proteins physically interact with a member of the BOTRYTIS SUSCEPTIBLE1 INTERACTOR (BOI) protein family and bind to GA-regulated gene promoters to repress GA-induced responses like seed germination, juvenile-to-adult phase transition, and flowering. DELLA proteins, consisting of GA INSENSITIVE, REPRESSOR OF GA1-3, RGA-LIKE1 (RGL1), RGL2, and RGL3, are central repressors of gibberellin (GA) responses, but their molecular functions are not fully understood. We isolated four DELLA-interacting RING domain proteins, previously designated as BOTRYTIS SUSCEPTIBLE1 INTERACTOR (BOI), BOI-RELATED GENE1 (BRG1), BRG2, and BRG3 (collectively referred to as BOIs). Single mutants of each BOI gene failed to significantly alter GA responses, but the boi quadruple mutant (boiQ) showed a higher seed germination frequency in the presence of paclobutrazol, precocious juvenile-to-adult phase transition, and early flowering, all of which are consistent with enhanced GA signaling. By contrast, BOI overexpression lines displayed phenotypes consistent with reduced GA signaling. Analysis of a gai-1 boiQ pentuple mutant further indicated that the GAI protein requires BOIs to inhibit a subset of GA responses. At the molecular level, BOIs did not significantly alter the stability of a DELLA protein. Instead, BOI and DELLA proteins are targeted to the promoters of a subset of GA-responsive genes and repress their expression. Taken together, our results indicate that the DELLA and BOI proteins inhibit GA responses by interacting with each other, binding to the same promoters of GA-responsive genes, and repressing these genes.
Procedural capacitor placement in differential charge-scaling converters by nonlinearity analysis

This paper presents a new approach to capacitor placement in differential charge-scaling data converters. Good capacitor matching is crucial for charge-scaling converter resolution. Differential circuits are preferred to single-ended architectures due to improved immunity to noise and variations. The proposed method is based on the analysis of converter static nonlinearity equations. The impact of capacitor variations on converter linearity is minimized by exploiting spatial correlation between devices. Mathematical analysis is completed for two differential analog-to-digital converters. A procedure to obtain a capacitor placement is presented for each circuit. The architectures are compared with respect to linearity and capacitor placement area.
Simple method for localisation of multiple tag-free targets using UWB sensor network

In this article we propose a low complexity algorithm for detection and localization of multiple targets using UWB sensor networks. We assume that the targets being tracked do not have any devices or tags attached. They are localized using scattered electromagnetic waves. Our envisaged sensor network consists of sensor nodes that can autonomously detect and localize the closest target. Those partial location estimates are mapped into images of an inspected area that are smoothed in time. This data fusion method does not require any data association or multi-hypothesis tests that are usually prerequisite in localization of multiple targets. This yields a significantly lower computational complexity compared to other algorithms. We demonstrate the performance of our algorithm by an experimental measurement using 6 sensor nodes.
Significance of Software Metrics in ERP Projects

Software engineering metrics are units of measurement that are used to characterize the software engineering products and processes. Enterprise resource planning (ERP) is a generic term for integrated systems. ERP projects are a subclass of software projects often accompanied by large-scale organizational changes. One of the major reasons found in the literature for the failure of ERP projects is the poor management of software processes. In this paper, we propose a software metrics plan (SMP) containing different software metrics to manage software processes during ERP implementation. Two hypotheses have been formulated and tested using statistical techniques to validate the SMP. The statistical analysis of the collected data from an ERP project supports the two hypotheses, leading to the conclusion that the software metrics are momentous in ERP projects
Learning to Drive using Inverse Reinforcement Learning and Deep Q-Networks

We propose an inverse reinforcement learning (IRL) approach using Deep Q-Networks to extract the rewards in problems with large state spaces. We evaluate the performance of this approach in a simulation-based autonomous driving scenario. Our results resemble the intuitive relation between the reward function and readings of distance sensors mounted at different poses on the car. We also show that, after a few learning rounds, our simulated agent generates collision-free motions and performs human-like lane change behaviour.
Reasoning about knowledge and probability

We provide a model for reasoning about knowledge and probability together. We allow explicit mention of probabilities in formulas, so that our language has formulas that essentially say "according to agent i, formula φ holds with probability at least α. " The language is powerful enough to allow reasoning about higher-order probabilities, as well as allowing explicit comparisons of the probabilities an agent places on distinct events. We present a general framework for interpreting such formulas, and consider various properties that might hold of the interrelationship between agents' subjective probability spaces at different states. We provide a complete axiomatization for reasoning about knowledge and probability, prove a small model property, and obtain decision procedures. We then consider the effects of adding common knowledge and a probabilistic variant of common knowledge to the language.
Home HVAC energy management and optimization with model predictive control

The general energy demand of the residential sector and the ensuing option for fossil fuels produce adverse results by both CO2, greenhouse gases (GHG) and extra air pollutant emissions. As domestic energy demand consists mostly of energy necessities for space and water heating alongside the energy dedicated for appliances, distinct strategies that target to foment a practical consumption of energy have to be reinforced at all levels of human activity. In this paper the aim is to make a comparison between proportional-integral-derivative (PID), thermostat (ON/OFF) control and Model Predictive Control (MPC) models of a domestic heating, ventilation and air conditioning (HVAC) system controlling the temperature of a room. The model of the household with local solar microgeneration is implicit to be located in a Portuguese city. The house of the case study is at the mercy to the local solar temperature, irradiance and 5 Time-of-Use (ToU) electricity rates applied on a complete week of August, 2016. The second purpose of this study is to assess which is the best electricity ToU rate option provided by the local electricity retailer for the residential sector.
