Accommodation recommendation system from user reviews based on feature-based weighted non-negative matrix factorization method

Nowadays, online information dominates people decision making, especially in a daily life basis, as well as traveling. Many websites provide accommodation information and reviews. Hence, this information overload makes choosing the right accommodation difficult and time-consuming for users. We propose ACRoSS, a system that collects data from websites and chooses representative reviews by feature-based weighted non-negative matrix factorization method regarding predetermined topics. The benefit of this project is to help users to choose an accommodation easily. The system can classify the topic with the precision of 61%. The percentages of users that have high satisfaction in representative reviews are 55.48%.
Sex-steroid derived compounds induce sex-specific effects on autonomic nervous system function in humans.

The physiological and psychological effects of 2 human sex-steroid derived compounds, 4.16-androstadien-3-one (AND) and l,3,5(10),16-estratetraen-3-ol(EST) were measured in 24 subjects who participated in a within-subjects, double-blind experiment. A dissociation was evident in the physiological effects of AND, in that it increased physiological arousal in women but decreased it in men. EST did not significantly affect physiological arousal in women or men. Neither compound significantly affected mood. AND is an androgen derivative that is the most prevalent androstene in human male sweat, male axillary hair, and on the male axillary skin surface. The authors argue that AND's opposite effects on physiology in men and women further implicate this compound in chemical communication between humans.
Adaptive Skin Color Classifier for Face Outline Models

Skin color is an important feature of faces. Applications that try to fit a face outline model to the real face contour can benefit from robust classification of skin and nonskin regions within the face. But this is a hard challenge, because skin color can look quite differently due to camera settings, illumination, shadows, people’s ethnic groups etc. In this work we present a parametric skin color classifier and its adaptation to the skin color conditions within an image or image sequence. To initialize the classificatory we apply a face detector to identify a subset of pixels, which are with high probability from the skin area. This approach can distinguish skin color from very similar colors like lip color or eye brow color. Its high speed and high accuracy makes it appropriate for real time applications such as face tracking and mimic recognition.
Axisymmetric and Triaxial MOND Density-Potential Pairs

We present a simple method, based on the deformation of spherically symmetric potentials, to construct explicit axisymmetric and triaxial MOND density-potential pairs. General guidelines to the choice of suitable deformations, so that the resulting density distribution is nowhere negative, are presented. This flexible method offers for the first time the possibility of studying the MOND gravitational field for sufficiently general and realistic density distributions without resorting to sophisticated numerical codes. The technique is illustrated by constructing the MOND density-potential pair for a triaxial galaxy model that, in the absence of deformation, reduces to the Hernquist sphere. Such analytical solutions are also relevant for testing and validating numerical codes. Here we present a new numerical potential solver designed to solve the MOND field equation for arbitrary density distributions: the code is tested with excellent results against the analytic MOND triaxial Hernquist model and the MOND razor-thin Kuzmin disk, and a simple application is finally presented.
A principled approach to nondeferred reference-counting garbage collection

Nondeferred reference-counting (RC) garbage collection is among the oldest memory-management methods. Despite offering unique advantages, little attention has been paid on how to correctly implement it for modern programming languages. This paper revisits this collection method and describes how to implement it for a modern object-oriented language in an optimizing compiler. The main contribution is a general algorithm that realizes one form of nondeferred RC collection for an object-oriented language having features such as exceptions, interior pointers, and object pinning. The algorithm abstracts the pertinent characteristics of instructions using concepts from data-flow analysis, such as def/use information, so that instructions are handled in a uniform manner, instead of in an ad hoc or special-case way. The abstracted information is used to systematically compute what increments and decrements to do, even in the presence of subtle conditions such as exceptional control flow. These techniques enabled us to compile a large suite of programs to use nondeferred RC collection. The paper also discusses the modifications that were necessary in the compiler for supporting the inserted RC operations, and reports measurements from a reference implementation.
Late-Onset Sacsinopathy Diagnosed by Exome Sequencing and Comparative Genomic Hybridization

Abstract Abstract: The molecular diagnosis of adult-onset autosomal recessive cerebellar ataxias remains challenging because of genetic heterogeneity. However, recently developed molecular genetic techniques will potentially revolutionize the diagnostic approach. Here we set out to define the genetic basis of the ataxia in two brothers with no molecular diagnosis. Clinical evaluation was followed by whole-exome second-generation sequencing and comparative genomic hybridization to determine the diagnosis. Whole-exome sequencing identified a hemizygous novel spastic ataxia of Charlevoix-Saguenay (SACS) stop-codon mutation in both brothers (c.13048G→T, p.E4350*) that was present in the mother, but not the father. Comparative genomic hybridization revealed a 0.7-Mb deletion on chromosome 13q12.12 in both brothers, which included SACS and was heterozygous in the asymptomatic father. The milder phenotype, caused by a whole-gene deletion and a stop-codon mutation in SACS, indicates a loss-of-function mechanism in late-onset autosomal recessive spastic ataxia of Charlevoix-Saguenay (ARSACS), and illustrates the importance of chromosomal rearrangements in the investigation of adult-onset ataxia.
Estimation of Offshore Wind Resources in Coastal Waters off Shirahama Using ENVISAT ASAR Images

Offshore wind resource maps for the coastal waters off Shirahama, Japan were made based on 104 images of the Advanced Synthetic Aperture Radar (ASAR) onboard the ENVISAT satellite. Wind speed fields were derived from the SAR images with the geophysical model function CMOD5.N. Mean wind speed and energy density were estimated using the Weibull distribution function. These accuracies were examined in comparison with in situ measurements from the Shirahama offshore platform and the Southwest Wakayama buoy (SW-buoy). Firstly, it was found that the SAR-derived 10 m-height wind speed had a bias of 0.52 m/s and a RMSE of 2.33 m/s at Shirahama. Secondly, it was found that the mean wind speeds estimated from SAR images and the Weibull distribution function were overestimated at both sites. The ratio between SAR-derived and in situ measured mean wind speeds at Shirahama is 1.07, and this value was used for a long-term bias correction in the SAR-derived wind speed. Finally, mean wind speed and wind energy density maps at 80 m height were made based on the corrected SAR-derived 10 m-height wind speeds and the ratio U80/U10 calculated from the mesoscale meteorological model WRF.
A National Patient-Centered E-Health Solution - The Experience from Down Under To-Date with the Personally Controlled Electronic Health Record (PCEHR)

Given the current pressures on healthcare delivery to be cost effective yet provide high quality, healthcare systems are turning to ICT (information communication technology) to help resolve this conundrum. Such e-health solutions range from being on one-side patient controlled to the other end of the spectrum being provider controlled. However, most agree that these solutions should be patient-centric. Australia has opted for a unique solution in an attempt to have the best of both worlds; i.e, some level of patient control and some level of provider control. This system is known as the PCEHR (personally controlled electronic health record). The following serves to investigate this system and if it is patient centric. In particular, how well patient focus, patient activity and patient empowerment are supported and/or enabled.
COSMIC: mining complete cancer genomes in the Catalogue of Somatic Mutations in Cancer

COSMIC (http://www.sanger.ac.uk/cosmic) curates comprehensive information on somatic mutations in human cancer. Release v48 (July 2010) describes over 136 000 coding mutations in almost 542 000 tumour samples; of the 18 490 genes documented, 4803 (26%) have one or more mutations. Full scientific literature curations are available on 83 major cancer genes and 49 fusion gene pairs (19 new cancer genes and 30 new fusion pairs this year) and this number is continually increasing. Key amongst these is TP53, now available through a collaboration with the IARC p53 database. In addition to data from the Cancer Genome Project (CGP) at the Sanger Institute, UK, and The Cancer Genome Atlas project (TCGA), large systematic screens are also now curated. Major website upgrades now make these data much more mineable, with many new selection filters and graphics. A Biomart is now available allowing more automated data mining and integration with other biological databases. Annotation of genomic features has become a significant focus; COSMIC has begun curating full-genome resequencing experiments, developing new web pages, export formats and graphics styles. With all genomic information recently updated to GRCh37, COSMIC integrates many diverse types of mutation information and is making much closer links with Ensembl and other data resources.
Characterization of Caspase Processing and Activation in HL-60 Cell Cytosol Under Cell-free Conditions

The present studies compared caspase activation under cell-free conditions in vitro and in etoposide-treated HL-60 leukemia cells in situ. Immunoblotting revealed that incubation of HL-60 cytosol at 30 °C in the presence of cytochrome c and ATP (or dATP) resulted in activation of procaspases-3, -6, and -7 but not -2 and -8. Although similar selectivity was observed in intact cells, affinity labeling revealed that the active caspase species generated in vitroand in situ differed in charge and abundance. ATP and dATP levels in intact HL-60 cells were higher than required for caspase activation in vitro and did not change before caspase activation in situ. Replacement of ATP with the poorly hydrolyzable analogs 5′-adenylyl methylenediphosphate, 5′-adenylyl imidodiphosphate, or 5′-adenylyl-O-(3-thiotriphos-phate) slowed caspase activation in vitro, suggesting that ATP hydrolysis is required. Caspase activation in vitro was insensitive to phosphatase and kinase inhibitors (okadaic acid, staurosporine, and genistein) but was inhibited by Zn2+, aurintricarboxylic acid, and various protease inhibitors, including 3,4-dichloroisocoumarin,N α-p-tosyl-l-phenylalanine chloromethyl ketone,N α-p-tosyl-l-lysine chloromethyl ketone, andN-(N α-benzyloxycarbonylphenylalanyl)alanine fluoromethyl ketone, each of which inhibited recombinant caspases-3, -6, -7, and -9. Experiments with anti-neoepitope antiserum confirmed that these agents inhibited caspase-9 activation. Collectively, these results suggest that caspase-9 activation requires nucleotide hydrolysis and is inhibited by agents previously thought to affect apoptosis by other means.
The Liberation of Fractalkine in the Dorsal Horn Requires Microglial Cathepsin S

Understanding of the sequence and nature of the events that govern neuron–microglia communication is critical for the discovery of new mechanisms and targets for chronic pain treatment. The neuronal chemokine fractalkine (FKN) and its microglial receptor CX3CR1 may mediate such a function in the dorsal horn of the spinal cord after cleavage of the extracellular domain of this transmembrane chemokine by a protease. Here we report that in neuropathic rat dorsal horn, with dorsal root-attached preparations, soluble FKN (sFKN) contents are increased in the superfusates collected after noxious-like electrical stimulation of ipsilateral primary afferent fibers. The increase of sFKN is prevented by morpholinurea-leucine-homophenylalanine-vinyl sulfone-phenyl (LHVS), an irreversible inhibitor of cathepsin S (CatS) whose proteolytic activity is also increased in the superfusates. The source of CatS activity is microglial cells activated by the peripheral nerve injury and secreting the enzyme, as a result of primary afferent fiber stimulation. Indeed, the acute activation of dorsal horn microglia by lipopolysaccharide results in increased CatS activity in the superfusates, followed by increased sFKN contents. Consistent with these observations ex vivo, the levels of both sFKN and CatS activity in CSF samples increased significantly after peripheral nerve injury, associated with spinal microglial activation. Finally, because we found that both FKN immunoreactivity and mRNA are confined to dorsal horn neurons, we suggest that under neuropathic conditions, noxious stimulation of primary afferent fibers induces release of CatS from microglia, which liberates FKN from dorsal horn neurons, thereby contributing to the amplification and maintenance of chronic pain.
A Chandra Study of Particle Acceleration in the Multiple Hot Spots of Nearby Radio Galaxies

We present Chandra observations of a small sample of nearby classical double radio galaxies that have more than one radio hot spot in at least one of their lobes. The X-ray emission from the hot spots of these comparatively low-power objects is expected to be synchrotron in origin, and therefore to provide information about the locations of high-energy particle acceleration. In some models of the relationship between the jet and hot spot, the hot spots that are not the current jet termination points should be detached from the energy supply from the active nucleus, and therefore not capable of accelerating particles to high energies. We find that in fact some secondary hot spots are X-ray sources, and thus probably locations for high-energy particle acceleration after the initial jet termination shock. In detail, however, we show that the spatial structures seen in X-rays are not consistent with naive expectations from a simple shock model: the current locations of the acceleration of the highest energy observable particles in powerful radio galaxies need not be coincident with the peaks of radio or even optical emission.
Bridging the Gap between Flexibility and Rigidity: Unifying Relationships with a Hybrid Link Architecture

Current knowledge systems lack an effective architecture to bridge the well-acknowledged gap between flexibility and rigidity users’ preference of flexible expression and machine’s need for rigorous representation. This paper focuses on finding an adequate set of relationship types (or link types) and map flexible expressions from users to link types in propositional knowledge systems, in which knowledge elements are stored as “concept-relationship-concept” triplets. We call our approach “hybrid link architecture”. This architecture has two levels of presentations, an open link name layer and a closed link type layer. Between these two layers is a matching mechanism based on a psycholinguistic thesaurus to map names to types. The link types are derived by synthesizing literature of knowledge organization, semantic network, and educational taxonomies. A two-stage evaluation is conducted based on 39,706 triplets. The evaluation shows that the matching mechanism is accurate and the proposed link types are mutually exclusive and cover most link names in our dataset.
WYSIWYE: An Algebra for Expressing Spatial and Textual Rules for Visual Information Extraction

The visual layout of a webpage can provide valuable clues for certain types of Information Extraction (IE) tasks. In traditional rule based IE frameworks, these layout cues are mapped to rules that operate on the HTML source of the webpages. In contrast, we have developed a framework in which the rules can be specified directly at the layout level. This has many advantages, since the higher level of abstraction leads to simpler extraction rules that are largely independent of the source code of the page, and, therefore, more robust. It can also enable specification of new types of rules that are not otherwise possible. To the best of our knowledge, there is no general framework that allows declarative specification of information extraction rules based on spatial layout. Our framework is complementary to traditional text based rules framework and allows a seamless combination of spatial layout based rules with traditional text based rules. We describe the algebra that enables such a system and its efficient implementation using standard relational and text indexing features of a relational database. We demonstrate the simplicity and efficiency of this system for a task involving the extraction of software system requirements from software product pages.

Exploring the parahippocampal cortex response to high and low spatial frequency spaces

The posterior parahippocampal cortex (PHC) supports a range of cognitive functions, in particular scene processing. However, it has recently been suggested that PHC engagement during functional MRI simply reflects the representation of three-dimensional local space. If so, PHC should respond to space in the absence of scenes, geometric layout, objects or contextual associations. It has also been reported that PHC activation may be influenced by low-level visual properties of stimuli such as spatial frequency. Here, we tested whether PHC was responsive to the mere sense of space in highly simplified stimuli, and whether this was affected by their spatial frequency distribution. Participants were scanned using functional MRI while viewing depictions of simple three-dimensional space, and matched control stimuli that did not depict a space. Half the stimuli were low-pass filtered to ascertain the impact of spatial frequency. We observed a significant interaction between space and spatial frequency in bilateral PHC. Specifically, stimuli depicting space (more than nonspatial stimuli) engaged the right PHC when they featured high spatial frequencies. In contrast, the interaction in the left PHC did not show a preferential response to space. We conclude that a simple depiction of three-dimensional space that is devoid of objects, scene layouts or contextual associations is sufficient to robustly engage the right PHC, at least when high spatial frequencies are present. We suggest that coding for the presence of space may be a core function of PHC, and could explain its engagement in a range of tasks, including scene processing, where space is always present.
Eliciting Emotions in Design of Games - a Theory Driven Approach

As technology becomes more powerful, computer software and game designers have ever-expanding tools available to create immersive, emotional experiences. Until recently, designing emotional experiences was achieved by veteran designers relying on insights from film theory and intuitions developed through years of practice. We propose another approach: leveraging scientific knowledge of emotions to guide the design process. The approach can serve as a resource for fledgling designers trying to break into the field, but will hopefully provide a few new insights for veterans as well. In addition, it may interest emotion researchers and psychologists looking to expand their stimulus repertoire. As a necessary underpinning for the design process, we will discuss several theoretical psychological models of emotions. Classical theories largely treat emotions as basic, universal states that are invariantly evoked by specific stimuli. While intuitive and popular, these theories are not well supported by current evidence. In contrast, a psychological constructionist theory, called the Conceptual Act Theory [6] proposes that emotions are constructed when conceptual knowledge is applied to ever changing affective experiences. The CAT proposes that emotional states can exhibit strong variation across instances and individuals due to differences in situational factors, learning histories and cultural backgrounds. This theory better fits available data, and also provides a framework for modeling emotional changes that vary by situation, person, and culture. The CAT also fits better with the game design process, since it treats users holistically as individuals. During the course of a game, similar to real life, emotions emerge from evaluations of situations and can therefore not be deterministically dictated by a single stimulus. Using the CAT framework, we developed a process to create affective digital game scenarios. Our goal is to give game designers, a scientific framework to better guide the design process.

Generalized Dynamic Semi�?Parametric Factor Models for High�?Dimensional Non�?Stationary Time Series

High‐dimensional non‐stationary time series, which reveal both complex trends and stochastic behaviour, occur in many scientific fields, e.g. macroeconomics, finance, neuroeconomics, etc. To model these, we propose a generalized dynamic semi‐parametric factor model with a two‐step estimation procedure. After choosing smoothed functional principal components as space functions (factor loadings), we extract various temporal trends by employing variable selection techniques for the time basis (common factors). Then, we establish this estimator's non‐asymptotic statistical properties under the dependent scenario (β‐mixing and m‐dependent) with the weakly cross‐correlated error term. At the second step, we obtain a detrended low‐dimensional stochastic process that exhibits the dynamics of the original high‐dimensional (stochastic) objects and we further justify statistical inference based on this. We present an analysis of temperature dynamics in China, which is crucial for pricing weather derivatives, in order to illustrate the performance of our method. We also present a simulation study designed to mimic it.
