A conditional tree based novel algorithm for high utility itemset mining

In recent years, the problem of high utility pattern mining become one of the most important research area in data mining. The problem is challenging, due to non applicability of anti-monotone property. The existing high utility mining algorithm generates large number of candidate itemsets, which takes much time to find utility value of all candidate itemsets, especially for dense datasets. In this paper, a novel conditional high utility tree (CHUT) is proposed to compress transactional databases in two stages to reduce search space and a new algorithm called HU-Mine is proposed to mine complete set of high utility item sets. The proposed algorithm needs only two database scans in contrasts to many scans of existing algorithm. The results of the proposed work are compared with existing benchmark algorithm.
A study of resonance tongues near a Chenciner bifurcation using MatcontM

MatcontM is a matlab toolbox for numerical analysis of bifurcations of fixed points and periodic orbits of maps. It computes codim 1 bifurcation curves and supports the computation of normal coefficients including branch switching from codim 2 points to secondary curves. Recently, the initialization and computation of connecting orbits was improved. Moreover, a graphical user interface was added enabling interactive control of all these computations. To further support these computations it allows to compute orbits of the map and its iterates and to represent them in 2D, 3D and numeric windows. We demonstrate the use of the toolbox in a study of Arnol'd tongues near a degenerate Neimark-Sacker (Chenciner) bifurcation. Here we illustrate the recent theory of [Baesens&Mackay,2007] how resonance tongues interact with a quasi-periodic saddle-node bifurcation of invariant curves in maps. Using normal form coefficients we find evidence for one of their cases, but not the other. Actually, we find another unfolding, i.e. a third possibility. We also find a structure that resembles a quasi-periodic cusp bifurcation of invariant curves.
1 Plan-based models of dialogue

This paper reviews plan-based models of dialogue. The original model is thoroughly presented. Important developments of the original model are also presented. Finally, benefits and drawbacks of plan-based approaches to dialogue modelling are discussed. Introduction Plan-based dialogue models have since long earned their place in works intended to present computational linguistics in general and dialogue systems in particular (Allen, 1995; Jurafsky and Martin, 2000; McTear, 2002). Plan-based models of dialogue have accomplished to offer a generalization where dialogue can be treated as a special case of rational non-communicative behaviour (Cohen, 1996). This paper intends to review plan-based models from when they first appeared and onward. The starting point is taken to be the seminal work of Cohen, Perrault, and Allen (Cohen and Perrault, 1979; Perrault and Allen, 1980; Allen and Perrault, 1980). Plan-based Models of Dialogue Plan-based models of dialogue can be claimed to originate from three classic papers: Cohen and Perrault (1979), Perrault and Allen (1980), and Allen and Perrault (1980). Perhaps, the easiest way to introduce this class of models is to start with an intuitive description of what happens when an agent A asks another agent B a question, to which the latter then responds. The presentation is taken from Allen and Perrault (1980). A has a goal to acquire certain information. This causes him to create a plan that involves asking B a question. B will hopefully possess the sought information. A then executes the plan, and thereby asks B the question. B will now receive the question and attempt to infer A’s plan. In the plan there might be goals that A cannot achieve without assistance. B can accept some of these obstacles as his own goals and create a plan to achieve them. B will then execute his plan and thereby respond to A’s question.
Thread scheduling for out-of-core applications with memory server on multicomputers

Out-of-core applications perform poorly in paged virtual memory (VM) systems because demand paging involves slow disk I/O accesses. Much research has been done on reducing the I/O overhead in such applications by either reducing the number of I/Os or lowering the cost of each I/O operation. In this paper, we investigate a method that combines ﬁne-grained threading with a memory server model to improve the performance of out-of-core applications on multicomput-ers. The memory server model decreases the average cost of I/O operations by paging to remote memory, while the ﬁne-grained thread scheduling reduces the number of I/O accesses by improving the data locality of applications. We have evaluated this method on an Intel Paragon with 7 applications. Our results show that the memory server system performs better than the VM disk paging by a factor of 5 for sequential applications and a factor of 1.5 to 2.2 for parallel applications. The ﬁne-grained threading alone improves the VM disk paging performance by a factor of 10 and 1.2 to 3 respectively for sequential and parallel applications. Overall, the combination of these two techniques outperforms the VM disk paging by more than a factor of 12 for sequential applications and a factor of 3 to 6 for parallel applications.
MANAGERIAL APPLICATIONS OF FRAMING EFFECTS AND MENTAL ACCOUNTING IN NETWORK PARTICIPATION

Metropolis such as Tehran might be treated as an example of the cities on their ways to be modernized being faced with emerging problems and issues. With respect to the efficiency of the civil sophisticated experts' ideas for resolving the civic difficulties, an intelligent database named “Idea Bank” has been implemented in Tehran municipality since 2009. The aim of this paper is showing some solutions for enhancing the efficiency and effectiveness of the idea bank system based on framing effects (FE). Based on extensive review of FE, broad ranges of general case of FE are identified. Then, through field studies and using questionnaire tools, the degree of the applicability of each particular FE lows is determined. The research procedure finally led to the identification of applicable FE in enhancing the performance of idea bank network. The results show the application of sunk cost, bundle/unbundle framing of outcomes and Penny-a-day strategy can effect on generating ideas in the idea bank. Also Pseudo certainty effect could reduce idea bank's awards expenses even the amount of reduction illustrated quantitatively. This work contributes to a more innovative view at framing effects and its psychological effects on effectiveness of expert's decision making in the idea bank. The results of this study could be applied similarly in enhancing the productivity of suggestion systems in organizations or even in contributing of experts in social networks. The paper should be of value to researchers of FE in general, and to implementers of FE theory programs in social networks.

Internal kinematics of spiral galaxies in distant rich galaxy clusters

We present our project on galaxy evolution in the environment of distant rich clusters aiming at disentangling the importance of specific interaction and galaxy transformation processes from the hierarchical evolution of field galaxies. Spatially resolved MOS spectra were gained with VLT/FORS to analyze the internal kinematics of disk galaxies. First results are shown for the clusters MS 1008.1–1224 ($z=0.30$), Cl 0303+1706 ($z=0.42$), and Cl 0413–6559 ($z=0.51$). Out of 35 late-type cluster members, 13 galaxies exhibit a rotation curve of the universal form rising in the inner region and passing over into a flat part. The other members have peculiar kinematics. The 13 cluster galaxies for which a maximum rotation velocity could be derived are distributed in the Tully-Fisher diagram very similarly to field galaxies from the FORS Deep Field with corresponding redshifts. The same is true for seven non-cluster galaxies observed in the cluster fields. The TF-cluster spirals do not show any significant luminosity evolution as might be expected from certain phenomena specific to clusters. Contrary to that, the disturbed kinematics of the non–TF cluster spirals indicate ongoing or recent interaction processes.To search for other articles by the author(s) go to: http://adsabs.harvard. edu/abstract_service. html
Implementation of Network Application Layer Parser for Multiple TCP/IP Flows in Reconfigurable Devices

This paper presents an implementation of a high-performance network application layer parser in FPGAs. At the core of the architecture resides a pattern matcher and a parser. The pattern matcher scans for patterns in high-speed streaming TCP data streams. The parser core augments each pattern found with semantic information determined from the patterns location within the data stream. The packet payload parser can provide a higher level of understanding of a data stream for many network applications. Such applications include high performance XML parsers, content-based/aware routers, and others. Additionally, a TCP processor allows stateful packet payload parsing of up to 8 million simultaneous TCP flows. The payload parser has been implemented in a Xilinx Virtex E 2000 FPGA on the Field-Programmable Port Extender platform. The parsing module runs at 200 MHz and parse raw data at 6.4 Gbps. The payload parser, integrated with the TCP processor, runs at 100 MHz for a throughput of 3.2 Gbps
Authenticating Aggregate Range Queries over Dynamic Multidimensional Dataset

We are interested in the integrity of the query results from an outsourced database service provider. Alice passes a set D of d-dimensional points, together with some authentication tag T, to an untrusted service provider Bob. Later, Alice issues some query over D to Bob, and Bob should produce a query result and a proof based on D and T. Alice wants to verify the integrity of the query result with the help of the proof, using only the private key. In this paper, we consider aggregate query conditional on multidimensional range selection. In its basic form, a query asks for the total number of data points within a d-dimensional range. We are concerned about the number of communication bits required and the size of the tag T. Xu and Chang [1] proposed a new method to authenticate aggregate count query conditional on d-dimensional range selection over static dataset, with O(d logN) communication bits, where N is the number of points in the dataset D. We extend their method to suport other types of queires, including summing, finding of the minimum/maximum/median and usual (non-aggregate) range selection, with similar complexity. Furthermore, dynamic operations, like insertion and deletion, over the outsourced dataset are also supported.
The Meaning of Play for Adults from a Reversal Theory Perspective

Play is important to adults’ mental creativity and happiness (Marano, 1999), and stress reduction (Apter, 2009a; Baptiste, 1995). Yet play may be considered as trivial behavior that is not appropriate for the adult population. The purpose of the study was to examine how adults describe the concept of play and to determine whether this description reflects their dominant metamotivational state. According to reversal theory, these states are the frames of mind that characterize an individual’s motivation at any given point in time (Apter, 1982). An individual tends to be in a more playful (paratelic) state or serious-minded (telic) state depending upon the circumstances at any particular moment. One hundred fifty-six adults between 40 and 65 years of age (Mage = 51.8) participated in the study. Data collection was accomplished entirely online through the Paratelic Dominance Scale and the submission of written narratives describing the meaning of a memorable episode of play in participants’ own words. A new instrument developed for this study intended to quantify the words used to describe play found no correlation between an individual’s dominant motivational state and the words that they use to describe play (r = -.024, p = .85) . However, several themes emerged from the written narratives including play as: fun, relaxation, being in the moment, along with goal-oriented play. These themes supported previous research findings (Csikszentmihalyi, 1975; Jackson, 1995; Stebbins, 2007; Yarnal et al., 2008) The current study demonstrated that examining the words people use to describe play is not enough to understand the meaning that play has for them. Understanding one’s tendency to be paratelic or telic is useful in the sense that the value of play is revealed to the individual, but it is equally important to understand that this view depends on the situation at the time of its occurrence. While a relationship was not found, it did provide valuable insight into how play was viewed by the adults who participated in the study. Understanding the complexity with which adults view play may help practitioners in the field with the provision of programs and services for this age group.
Genetic Evidence Supports the Multiethnic Character of Teopancazco, a Neighborhood Center of Teotihuacan, Mexico (AD 200-600)

Multiethnicity in Teopancazco, Teotihuacan, is supported by foreign individuals found in the neighborhood center as well as by the diversity observed in funerary rituals at the site. Studies of both stable and strontium isotopes as well as paleodietary analysis, suggest that the population of Teopancazco was composed by three population groups: people from Teotihuacan, people from nearby sites (Tlaxcala-Hidalgo-Puebla), and people from afar, including the coastal plains. In an attempt to understand the genetic dynamics in Teopancazco we conducted an ancient DNA (aDNA) analysis based on mtDNA. Our results show that the level of genetic diversity is consistent with the multiethnicity phenomenon at the neighborhood center. Levels of genetic diversity at different time periods of Teopancazco’s history show that multiethnicity was evident since the beginning and lasted until the collapse of the neighborhood center. However, a PCA and a Neighbor-Joining tree suggested the presence of a genetically differentiated group (buried at the Transitional phase) compared to the population from the initial phase (Tlamimilolpa) as well as the population from the final phase (Xolalpan) of the history of Teopancazco. Genetic studies showed no differences in genetic diversity between males and females in the adult population of Teopancazco, this data along with ample archaeological evidence, suggest a neolocal post-marital pattern of residence in Teopancazco. Nevertheless, genetic analyses on the infant population showed that the males are significantly more heterogeneous than the females suggesting a possible differential role in cultural practices by sex in the infant sector. Regarding interpopulation analysis, we found similar indices of genetic diversity between Teopancazco and heterogeneous native groups, which support the multiethnic character of Teopancazco. Finally, our data showed a close genetic relationship between Teopancazco and populations from the “Teotihuacan corridor” and from Oaxaca and the Maya region, in agreement with previous archaeological evidence.
Automated Design Optimization for Hypersonic

An automated design methodology incorporating industry-standard Navier-Stokes codes and a gradient-based optimizer has been developed. This system is used to redesign the well-known NASA P2 and P8 hypersonic inlets. First, the Navier-Stokes simulations of the original P2 and P8 inlet designs are validated using numerical convergence studies and comparison with wind-tunnel experimental data for the original inlets published by NASA in the early 1970s. Second, the P2 and P8 inlets are redesigned with the objective of canceling the cowl shock (and, in the case of the P8 inlet, the additional cowl-generated compression) at the centerbody by appropriate contouring of the centerbody boundary. The original inlets were intended to achieve these same objectives, but detailed experimental measurements indicated that a substantial re-ected shock system was present. We have obtained several diierent redesigns which achieve approximate cancellation of the cowl shock and additional cowl-generated compression. The choice of the objective function, which is used to drive the optimization, has a signiicant impact on the nal design. Several diierent formulations for the objective function have been employed, and improvements of 60% to 90% in the objective function have been achieved. This automated design system represents one of the rst successful combinations of numerical optimization methods with Reynolds-averaged Navier-Stokes uid dynamics simulation for high speed inlets, and demonstrates a new area in which High Performance Computing may have considerable impact on problems of military and industrial signiicance.
Abnormal Temporal Coupling of Tactile Perception and Motor Action in Parkinson’s Disease

Evidence shows altered somatosensory temporal discrimination threshold (STDT) in Parkinson’s disease in comparison to normal subjects. In healthy subjects, movement execution modulates STDT values through mechanisms of sensory gating. We investigated whether STDT modulation during movement execution in patients with Parkinson’s disease differs from that in healthy subjects. In 24 patients with Parkinson’s disease and 20 healthy subjects, we tested STDT at baseline and during index finger abductions (at movement onset “0”, 100, and 200 ms thereafter). We also recorded kinematic features of index finger abductions. Fifteen out of the 24 patients were also tested ON medication. In healthy subjects, STDT increased significantly at 0, 100, and 200 ms after movement onset, whereas in patients with Parkinson’s disease in OFF therapy, it increased significantly at 0 and 100 ms but returned to baseline values at 200 ms. When patients were tested ON therapy, STDT during index finger abductions increased significantly, with a time course similar to that of healthy subjects. Differently from healthy subjects, in patients with Parkinson’s disease, the mean velocity of the finger abductions decreased according to the time lapse between movement onset and the delivery of the paired electrical stimuli for testing somatosensory temporal discrimination. In conclusion, patients with Parkinson’s disease show abnormalities in the temporal coupling between tactile information and motor outflow. Our study provides first evidence that altered temporal processing of sensory information play a role in the pathophysiology of motor symptoms in Parkinson’s disease.
Phase pattern switching in star-coupled Wien-bridge oscillators driven by pulse train

Oscillators star-coupled by one resistor exhibit phase-shift synchronization and many different steady states exist according to their initial states. Therefore, we have suggested that these systems can be use as structural elements of neural networks and large scale memories. In such cases, to obtain appropriate phase patterns, controlling the phase patterns is an important problem. In this study, we propose Wien-bridge oscillators star-coupled by one resistor driven by a periodic pulse train. In this system, the phase pattern switching is caused by stimulation of the pulse. From the results, we suggest that pulse stimulation is one way to control the phase patterns in coupled oscillator systems.
Allocating images and selecting image collections for distributed visual search

To improve query throughput, distributed image retrieval has been widely used to address the large scale visual search. In textual retrieval, the state-of-the-art approaches attempt to partition a textual database into multiple collections offline and allocate each collection to a server node. For each incoming query, just a few relevant collections are selected to search without seriously sacrificing retrieval accuracy, which enables sever nodes to process multiple queries concurrently. Unlike text retrieval, distributed visual search poses challenges in optimally allocating images and selecting image collections, due to the lack of semantic meanings in Bag of Words (BoW) based representation. In this paper, we propose a novel Semantics Related Distributed Visual Search (SRDVS) model. We employ Latent Dirichlet Allocation (LDA) [2] to discover the latent concepts as an intermediate semantic representation over a large scale image database. We aim to learn an optimal image allocation for each server node and accurately perform collection selection for each query. Experimental results over a million scale image database have demonstrated encouraging performance over state-of-the-art approaches. On average 6% collections are selected, which however yields promising retrieval performance comparable to the exhaustive search over the whole database.
Using Combined Lexical Resources to Identify Hashtag Types

This paper seeks to identify sentiment and non-sentiment bearing hashtags by com- bining existing lexical resources. By using a lexicon-based approach, we achieve 86.3% and 94.5% precision in identifying sentiment and non-sentiment hashtags, respectively. Moreover, results obtained from both of our classification models demonstrate that using combined lexical, emotion and word resources is more effective than using a single resource in identifying the two types of hashtags.
Neuronal Nitric Oxide Synthase Signaling in the Heart Is Regulated by the Sarcolemmal Calcium Pump 4b

Background— Neuronal nitric oxide synthase (nNOS) has recently been shown to be a major regulator of cardiac contractility. In a cellular system, we have previously shown that nNOS is regulated by the isoform 4b of plasma membrane calcium/calmodulin-dependent ATPase (PMCA4b) through direct interaction mediated by a PDZ domain (PSD 95, Drosophilia Discs large protein and Zona occludens-1) on nNOS and a cognate ligand on PMCA4b. It remains unknown, however, whether this interaction has physiological relevance in the heart in vivo. Methods and Results— We generated 2 strains of transgenic mice overexpressing either human PMCA4b or PMCA ct120 in the heart. PMCA ct120 is a highly active mutant form of the pump that does not interact with or modulate nNOS function. Calcium was extruded normally from PMCA4b-overexpressing cardiomyocytes, but in vivo, overexpression of PMCA4b reduced the &bgr;-adrenergic contractile response. This attenuated response was not observed in ct120 transgenic mice. Treatment with a specific nNOS inhibitor (N&ohgr;-propyl-l-arginine) reduced the &bgr;-adrenergic response in wild-type and ct120 transgenic mice to levels comparable to those of PMCA4b transgenic animals. No differences in lusitropic response were observed in either transgenic strain compared with wild-type littermates. Conclusions— These data demonstrate the physiological relevance of the interaction between PMCA4b and nNOS and suggests its signaling role in the heart.
