FluidPaint: an interactive digital painting system using real wet brushes

This paper presents FluidPaint, a novel digital paint system using real wet brushes. A new interactive canvas, accurately registering brush footprints and paint strokes in high precision has been developed. It is based on the real-time imaging of brushes and other painting instruments as well as the real-time co-located rendering of the painting results. This new painting user interface enhances the user experience and the artist's expressiveness. User tests demonstrate the intuitive nature of FluidPaint, naturally integrating interface elements of traditional painting in a digital paint system.
Part-of-Speech Tagging and Chunking with Maximum Entropy Model

This paper describes our work on Part-ofspeech tagging (POS) and chunking for Indian Languages, for the SPSAL shared task contest. We use a Maximum Entropy (ME) based statistical model. The tagger makes use of morphological and contextual information of words. Since only a small labeled training set is provided (approximately 21,000 words for all three languages), a ME based approach does not yield very good results. In this work, we have used a morphological analyzer to improve the performance of the tagger. The tagger uses variety of features, which works effectively not only for Bengali, but also for other Indian Languages such as Hindi and Telugu. The chunker makes use of only language independent contextual information. The work primarily focuses on the development of a Bengali POS tagger and chunker. Further, we have transported the model for Hindi and Telugu to understand the relative performance of the statistical model. The tagger has the overall accuracy on development data of about 88% for Bengali, and about 83% and 68% for Hindi and Telugu respectively. The best accuracy achieved for chunking by our method on the development data are 84.45%, 79.88% and 65.92% for Bengali, Hindi and Telugu respectively on per word basis.
Are You Looking at Me? Eye Gaze and Person Perception

Previous research has highlighted the pivotal role played by gaze detection and interpretation in the development of social cognition. Extending work of this kind, the present research investigated the effects of eye gaze on basic aspects of the person-perception process, namely, person construal and the extraction of category-related knowledge from semantic memory. It was anticipated that gaze direction would moderate the efficiency of the mental operations through which these social-cognitive products are generated. Specifically, eye gaze was expected to influence both the speed with which targets could be categorized as men and women and the rate at which associated stereotypic material could be accessed from semantic memory. The results of two experiments supported these predictions: Targets with nondeviated (i.e., direct) eye gaze elicited facilitated categorical responses. The implications of these findings for recent treatments of person perception are considered.

Combining Multi-Domain Statistical Machine Translation Models using Automatic Classifiers

This paper presents a set of experiments on Domain Adaptation of Statistical Machine Translation systems. The experiments focus on Chinese-English and two domain-specific corpora. The paper presents a novel approach for combining multiple domain-trained translation models to achieve improved translation quality for both domain-specific as well as combined sets of sentences. We train a statistical classifier to classify sentences according to the appropriate domain and utilize the corresponding domain-specific MT models to translate them. Experimental results show that the method achieves a statistically significant absolute improvement of 1.58 BLEU (2.86% relative improvement) score over a translation model trained on combined data, and considerable improvements over a model using multiple decoding paths of the Moses decoder, for the combined domain test set. Furthermore, even for domain-specific test sets, our approach works almost as well as dedicated domain-specific models and perfect classification.
Binary Decision Tree Classification of Musical Sounds

This paper presents a novel method of classifying musical sounds. An earlier work has shown the ability of a subset of the timbre attributes of musical sounds to classify musical sounds correctly in instrument families. This work focuses on the interpretation of the timbre attributes. The question is: which timbre attributes are useful for the classification of the sounds? These attributes are found by creating binary trees, the split questions of which are based on timbre attributes of musical sounds, including envelope, spectral envelope and noise parameters. The timbre attributes are calculated, from the additive parameters, for a large collection of musical instruments, generally for the full pitch range of each instrument. Experiments with recorded sounds from a variety of instruments have shown that the binary decision tree created with average entropy generally separates the instruments in few levels. Most sounds from each instrument are collected in separate terminal nodes. The tree created with the timbre data can be used to classify new, unknown sounds, and help understand which timbre attributes are pertinent in the identification of musical sounds.
Colicin U, a novel colicin produced by Shigella boydii

A novel colicin, designated colicin U, was found in two Shigella boydii strains of serovars 1 and 8. Colicin U was active against bacterial strains of the genera Escherichia and Shigella. Plasmid pColU (7.3 kb) of the colicinogenic strain S. boydii M592 (serovar 8) was sequenced, and three colicin genes were identified. The colicin U activity gene, cua, encodes a protein of 619 amino acids (Mr, 66,289); the immunity gene, cui, encodes a protein of 174 amino acids (Mr, 20,688); and the lytic protein gene, cul, encodes a polypeptide of 45 amino acids (Mr, 4,672). Colicin U displays sequence similarities to various colicins. The N-terminal sequence of 130 amino acids has 54% identity to the N-terminal sequence of bacteriocin 28b produced by Serratia marcescens. Furthermore, the N-terminal 36 amino acids have striking sequence identity (83%) to colicin A. Although the C-terminal pore-forming sequence of colicin U shows the highest degree of identity (73%) to the pore-forming C-terminal sequence of colicin B, the immunity protein, which interacts with the same region, displays a higher degree of sequence similarity to the immunity protein of colicin A (45%) than to the immunity protein of colicin B (30.5%). Immunity specificity is probably conferred by a short sequence from residues 571 to residue 599 of colicin U; this sequence is not similar to that of colicin B. We showed that binding of colicin U to sensitive cells is mediated by the OmpA protein, the OmpF porin, and core lipopolysaccharide. Uptake of colicin U was dependent on the TolA, -B, -Q, and -R proteins. pColU is homologous to plasmid pSB41 (4.1 kb) except for the colicin genes on pColU. pSB41 and pColU coexist in S. boydii strains and can be cotransformed into Escherichia coli, and both plasmids are homologous to pColE1.
The Impact of the Code of Conduct on the Academic and Non-academic Staff of a University in the Eastern Cape Province, South Africa

Abstract The code of conduct/ethics is acknowledged as an essential tool in curbing the high rate of corruption in most countries worldwide. Hence, the main purpose of this study is to investigate the impact of the code of conduct on the academic and non-academic staff at a university in the Eastern Cape Province. The study adopts a descriptive survey research design and simple random sampling techniques were used to select 45 (forty-five) respondents. The findings showed that forty-five percent of the academic and non-academic staffs of the university are aware of the use of code of conduct. Since the academic and nonacademic staff are aware of the use of code of conduct, proper discipline should be employed on an employee depending on the rules and regulations stipulated in the code of conduct. In conclusion, the institution can make use of the ‘whistleblowing’ mechanisms in reporting unethical activities, which leaves the employees protected and unknown.

Linear Voltage Stabilization System for Stop & Start vehicles

This article presents a new Linear Voltage Stabilization System (LVSS) specially meant for μ-hybrid vehicles using the “Stop & Start” function. The LVSS stabilize the battery voltage mainly during the start-up of the Internal Combustion Engine (ICE) limiting the load current using parallels MOSFETs working in linear mode [1]. The mains advantages are its small volume, avoid of EMC perturbations and specially its low price allowing Stop & Start vehicles to be more accessible to the market. The concept is validated testing the prototype in a real car.
A Simple Alternative Derivation of the Expectation Correction Algorithm

The switching linear dynamical system (SLDS) is a popular model in time-series analysis. However, the complexity of inferring the state of the latent variables scales exponentially with the length of the time-series, resulting in many approximation strategies in the literature. We focus on the recently devised expectation correction (EC) approximation which can be considered a form of Gaussian sum smoother. The algorithm has excellent numerical performance compared to a wide range of competing techniques, exploiting more fully the available information than, for example, generalised pseudo Bayes. We show that EC can be seen as an extension to the SLDS of the Rauch, Tung, Striebel inference algorithm for the linear dynamical system. This yields a simpler derivation of the EC algorithm and facilitates comparison with existing, similar approaches.
Ambient air pollution in China poses a multifaceted health threat to outdoor physical activity

While outdoor physical activity has been shown to promote health and well-being,1 ,2 exercising in environments with high levels of air pollution can increase the risk of health problems ranging from asthma attacks to heart or lung pathologies.3 ,4 The interaction of these two phenomena is of specific significance in China, where outdoor physical activity has been a traditional practice but where rapid industrialisation has led to major degradation of the environment. This situation raises the spectre of an emergent major public health crisis in the most populous country in the world. There is clear and compelling evidence that regular physical activity produces substantial physical and mental health benefits, including improved health-related quality of life and decreased risk of premature morbidity and mortality.1 ,5 ,6 However, it is important to note that in contrast to the commodification of exercise in many western industrialised nations, where exercise for health is often carried out in indoor facilities such as fitness centres, the physical and mental health benefits of physical activity can be achieved outdoors in settings such as community green spaces, parks and trails.1 ,2 Therefore, public health policies designed to encourage participation in physical activity should focus on outdoor settings for promoting public health and improving overall quality of life,5–8 because outdoors settings can accommodate a much larger scale population involvement at substantially lower costs than can physical activity in indoor facilities. In China, cultural norms, history and public policy have presaged this logistical reality, with a significant portion of the population, especially in the older demographic, exercising daily in outdoor settings such as parks, village squares and along streets, through leisure walking, jogging, dancing, bicycling or Tai Ji Quan.9–11 Studies in China have shown a positive association between traditional …
Contributions of the two accessory subunits, RNASEH2B and RNASEH2C, to the activity and properties of the human RNase H2 complex

Eukaryotic RNase H2 is a heterotrimeric enzyme. Here, we show that the biochemical composition and stoichiometry of the human RNase H2 complex is consistent with the properties previously deduced from genetic studies. The catalytic subunit of eukaryotic RNase H2, RNASEH2A, is well conserved and similar to the monomeric prokaryotic RNase HII. In contrast, the RNASEH2B and RNASEH2C subunits from human and Saccharomyces cerevisiae share very little homology, although they both form soluble B/C complexes that may serve as a nucleation site for the addition of RNASEH2A to form an active RNase H2, or for interactions with other proteins to support different functions. The RNASEH2B subunit has a PIP-box and confers PCNA binding to human RNase H2. Unlike Escherichia coli RNase HII, eukaryotic RNase H2 acts processively and hydrolyzes a variety of RNA/DNA hybrids with similar efficiencies, suggesting multiple cellular substrates. Moreover, of five analyzed mutations in human RNASEH2B and RNASEH2C linked to Aicardi-Goutières Syndrome (AGS), only one, R69W in the RNASEH2C protein, exhibits a significant reduction in specific activity, revealing a role for the C subunit in enzymatic activity. Near-normal activity of four AGS-related mutant enzymes was unexpected in light of their predicted impairment causing the AGS phenotype.
Torsion in coinvariants of certain Cantor minimal Z2-systems

Let G be a finite abelian group. We will consider a skew product extension of a product of two Cantor minimal Z-systems associated with a G-valued cocycle. When G is non-cyclic and the cocycle is non-degenerate, it will be shown that the skew product system has torsion in its coinvariants.
Secure emergency medical architecture on the cloud using wireless sensor networks for emergency detection

Recently introduced, Attribute-based encryption (ABE) is a promising cryptographic method proposed by Sahai and Waters. This technique provides means for designing scalable and fine-grained access control. In ABE, data are encrypted with an access structure which is the logical expression of the access policy (eg: the data can be accessed by physician in cardiology division or by nurses). The cyphertext (encrypted data) can be decrypted by any user if his secret key has attributes that satisfy the access policy. The power of ABE is that we do not need to rely on the storage server for avoiding unauthorized data access since the access policy is embedded in the cyphertext itself. This makes ABE good solution to provide a fine-grained access control for medical applications, where data is outsourced on untrusted servers like the case of the Cloud. However, for emergency management, integrating ABE creates particular challenges for providing temporary access victims medical data when this is needed. In this paper we present our architecture for secure emergency management in healthcare area. We address the challenge of ABE integrating for providing temporary access victims medical data in emergency situation. In addition, we use wireless sensor network (WSN) technology to provide early emergency detection.
Investigating the effects of propofol-induced tonic inhibition on rhythmic neural activity in a hippocampal interneuron network

Propofol is an anaesthetic agent commonly used in surgical operations for the induction and maintenance of general anaesthesia. Propofol-induced sedation is achieved by positively modulating GABAergic inhibitory activity, as the drug binds on GABA A receptors enhancing their activation [1]. GABA A receptors are ubiquitous in the brain [2], and can be present both within synap-tic clefts, as well as on extrasynaptic locations along the dendrites where they mediate tonic in-hibitory currents. Synaptic GABAergic interactions between sparsely connected interneurons are thought to play an important role in the generation and maintenance of rhythmic neural activity, in particular in the γ-band (20 − 80) Hz [3]. This oscillatory frequency range is often recorded in functionally-coupled brain regions for cooperation during memory tasks. One such example is cortico-hippocampal synchronisation during long-term memory consolidation [4]. This work studies the effect of propofol-induced tonic inhibition on the oscillations elicited in a network of hippocampal Hodgkin-Huxley GABA interneurons [3]. The action of propofol on extrasynaptic GABAergic receptors was modelled by varying the conductance g of a tonic current in the form Iton = g(V − Eton ) as described in [5]. To measure the synchronisation of the neural activity in the network we used the coherence metric K defined in [3], where a value of 1 indicates global synchrony across all neurons. In the absence of tonic inhibition g = 0nS, the network synchronises its activity with K = 0.4 at an oscillatory frequency of ∼ 43 Hz. Increasing doses of propofol reduce the overall network activity and slow down its oscillations until a critical value of g = 14nS at which the synchronisation increases abruptly reaching a plateau at K = 0.8, and the mean firing rate increases. These results point towards a possible mechanism for the emergence of paradoxical excitation under general anaesthesia.
Transistor-level test calculation for CMOS circuits

The paper presents a test calculation principle which serves for producing tests of transistor-level faults in CMOS digital circuits. The considered fault model includes stuck-at-0/1 logic faults on the connecting control lines, as well as switch faults in the transistors. Both single and multiple faults are included. The transistor faults manifest themselves in stuck open (open circuit) and stuck short (short circuit) behavior. In this paper only combinational logic circuits are taken into consideration. The calculation principle is comparatively simple. It is based only on successive line-value justification, and it yields an opportunity to be realized by an efficient computer program.
3.1 the Activator-substrate Model

non-transparent layers. Consequently, there is no evolutionary pressure giving a preference to specific patterns. The diversity of the patterns, which may differ in details even between shells of the same species, suggests a morphogenetic mechanism general enough to encompass large specimen-to-specimen and species-to-species variations. We assume that it is of the reaction-diffusion type [11, 16, 33]. Pigment deposition is under the control of a substance, called the activator, which stimulates its own production through a positive feedback mechanism, or autocatalysis. In order for a pattern to be formed, a mechanism is also needed for suppressing the production of the activator in the neighborhood of the autocatalytic centers. This prevents the activator from spreading over the entire substrate. Thus, the pattern is formed as a result of the antagonistic interaction between short-range activation and long-range inhibition. Harrison [13] points out that reaction-diffusion is not a single model, but the cornerstone of a whole spectrum of models, differing in the number and characteristics of the reacting substances. This observation remains true for the models of pigmentation patterns in shells. We do not capture all possible patterns in a single system of equations , but modify it according to the specific pattern. Generally, we group our models into two basic categories distinguished by Gierer and Meinhardt [11]: activator-substrate, and activator-inhibitor. The inhibitory effect may result from the depletion of the substrate required to produce the activator. A possible interaction is described by the following equations: @a @t = s a 2 1 + a 2 + 0 ? a + Da @ 2 a @x 2 @s @t = ? s a 2 1 + a 2 + 0 ? s + Ds @ 2 s @x 2 (8) The activator, with the concentration a, diffuses along the x-axis at the rate Da and decays at the rate. Similarly, the substrate, with the concentration s, diffuses at the rate Ds and decays at the rate. The substrate is produced at a constant rate. Production of the activator is an autocatalytic process, proportional to a 2 for small activator concentrations. This process can take place only in the presence of the substrate, and decreases its amount. Parameter is the coefficient of proportionality. The autocatalysis can saturate at high activator concentrations, at the level controlled by the parameter. Parameter 0 represents a small base production of the activator, needed to initiate the autocatalytic process. Figure …
