Local-Structure Adaptive Sparse Subspace Learning: An Iterative Approach to Unsupervised Feature Selection

Subspace learning is becoming more and more popular thanks to its capabilities of good interpretation. However, existing approaches do not adapt both local structure and self reconstruction very well. We propose local-structure adaptive sparse subspace learning (ASSL) model for unsupervised feature selection. In this paper, we formulate the feature selection process as a subspace learning problem and incorporate a regularization term to preserve the local structure of the data. Furthermore, we develop a greedy algorithm to establish the basic model and an iterative strategy based on an accelerated block coordinate descent is used to solve the local-structure ASSL problem. We also provide the global convergence analysis of the proposed ASSL algorithm. Extensive experiments are conducted on real-world datasets to show the superiority of the proposed approach over several state-of-the-art unsupervised feature selection approaches.
Masters Internship Report Extraction of information in large graphs; Automatic search for synonyms

I used the Online Plain Text English Dictionary (OPT 2000) which is based on the "Project Gutenberg Etext of Webster’s Unabridged Dictionary" which is in turn based on the 1913 US Webster’s Unabridged Dictionary. It consists in 27 HTML les (one for each letter of the alphabet, and one for several additions). The problem was to parse these les in order to build the graph of the dictionary: there is a vertex for every word and an arc from vertex i to vertex j if j appears in the denition of i. I encountered several problems in this operation: Some words dened in the Webster’s dictionary were in fact multi-words (e.g. All Saints’, Surinam toad). I decided not to include them into the graph, since there is no simple way, when you see two words side-byside, to decide whether they should be interpreted as single words or as a multi-word.
High speed packet forwarding compiled from protocol independent data plane specifications

P4 is a high level language for programming network switches that allows for great flexibility in the description of packet structure and processing, independent of the specifics of the underlying hardware. In this demo, we present our prototype P4 compiler in which the hardware independent and hardware specific functionalities are separated. We have identified the requisites of the latter, which form the interface of our target specific Hardware Abstraction Library (HAL); the compiler turns P4 code into a target independent core program that is linked to this library and invokes its operations. The two stage separation improves portability: to support a new architecture, only the hardware dependent library has to be implemented. In the demo, we demonstrate the flexibility of our compiler with a HAL for Intel DPDK, and show the packet processing and forwarding performance of compiled switches in different scenarios.
Knowledge Base for Database Design

1. INTRODUCTION This paper describes the database design knowledge of a computer-assisted database design tool, called the Intelligent Database Design Kit (IDDK): useil to develop database sy&ms. The IDDK knowledge base 1s stored in the form of a database dictionary based on an extended entity-relationship-ataibute model. The database dictionary is central to the knowledge engineering approach of the IDDK implementation strategy. The knowledge-based dictionary is a repository of meta-data (atomic facts, concepts. definitions, inference rules, heuristics) for a database system development. IDDK tools are developed using, to a large extent, semantic models and artificial intelligence techniques. The paper introduces computer-assisted extensions to Chen's entity-relationship model, in particular, recursive, subset, generic, and nested relationship concepts. An architecture and framework for intelligent database design is presented. The database design knowledge is divided into a declarative part (containing a description of entities, relationships and attributes) and a procedural part (defining design operations). While driving the IDDK tools, the knowledge base maintains basic consistency checks. In fact, the same methodology that supports the database design activities is used to implement the knowledge base. The IDDK interface to the knowledge base editor is based on a standard Macintosh interface extended with database design-oriented pallette icons and graphical editing tools. Retrospectively, database design has relied ujton human experience and judgement rather than mechanistic algcnithmS. The design task is usually performed by vltperts who obtain information about the users' needs through interviewing, examining existing documentation, and other traditional means. To this extent, the current approach suffers from two weaknesses: (1) it requires the use of a scarce resource-the expert database designer, and (2) the designer's knowledge of the application is necessarily second-band and some of its intricacies ,are likely to be overlooked. In our research, we respond to these problems by providing: (1) an expert system based set of tools, (2) a large lmowledge base ;IS a repository for information about the application and design activities. The Intelligent Database. Design Kit (IDDK) is a knowledge engineering project which integrates database technology. software engineering, and knowledge-based techniques. A key concept in this research is the use of a semantically extended conceptual model (entity-relationship (Chcn, 1976)) as the underlying formalism of the database design knowledge base, which in turn drives the IDDK tools. The paper extends the fonhcoming ANSI and IS0 standards for Information Resource Dictionary System IRDS (Dolk and Kirsch II, 1987; Goldfine, 1985). The extension is threefold: …
CONCEPTUALIZING DANCE LITERACY: A CRITICAL THEORETICAL PERSPECTIVE ON DANCE IN SCHOOL

SAMMANDRAG Under 2000-talet har anvandningen av begreppet danslitteracitet (dance literacy) okat och forskare argumenterar att fokus pa att utveckla elevers danslitteracitet kan belysa kroppsligt larande i skolan. Daremot anvands begreppet ofta utan definition och det verkar inte finnas nagon entydighet i vad danslitteracitet innebar for kroppsligt larande i skolsammanhang. Med utgangspunkt i tidigare forskningslitteratur syftar denna artikel till att utreda begreppet danslitteracitet, samt att genom en kritisk teoretisk lins diskutera danslitteracitet i en skolkontext. Diskussionen praglas av ett emancipatoriskt perspektiv pa danslitteracitet och resulterar i en foreslagen Modell for danslitteracitet i skolan i en undervisningskontext utan dans som skolamne. Modellen bestar av tre dimensioner: dans som konstform och uttrycksform, dans kombinerat med andra uttrycksformer, samt larande genom dans i olika amnen. I artikeln konstateras att undervisning med fokus pa danslitteracitet kan erbjuda elever mojligheter till kroppsligt larande i och genom dans, samtidigt som dansens varde i sig sjalv betonas och vardesatts.

A phylogenetic analysis of the British flora sheds light on the evolutionary and ecological factors driving plant invasions

Darwin's naturalization hypothesis predicts that invasive species should perform better in their novel range in the absence of close relatives in the native flora due to reduced competition. Evidence from recent taxonomic and phylogenetic-based studies, however, is equivocal. We test Darwin's naturalization hypothesis at two different spatial scales using a fossil-dated molecular phylogenetic tree of the British native and alien flora (ca. 1600 species) and extensive, fine-scale survey data from the 1998 Countryside Survey. At both landscape and local scales, invasive species were neither significantly more nor less related to the native flora than their non-invasive alien counterparts. Species invasiveness was instead correlated with higher nitrogen and moisture preference, but not other life history traits such as life-form and height. We argue that invasive species spread in Britain is hence more likely determined by changes in land use and other anthropogenic factors, rather than evolutionary history. Synthesis. The transition from non-invasive to invasive is not related to phylogenetic distinctiveness to the native community, but instead to their environmental preferences. Therefore, combating biological invasions in the Britain and other industrialized countries need entirely different strategies than in more natural environments.
Aspects of natural cold tolerance in ectothermic animals

Polar, alpine and temperate ectothermic (coldblooded) animals encounter temperatures below the melting point of their body fluids either diurnally or seasonally. These animals have developed a number of biochemical and physiological adaptations to survive the low temperatures. The problems posed to the animals during cold periods include changes in membrane and protein structure due to phase changes in these molecules, changes in electrolyte concentrations and other solutes in the body fluids as well as changes in metabolism. Coldtolerant ectothermic animals can be divided into two groups depending which of two 'strategies' they employ to survive the low temperatures: freeze-tolerant animals which survive ice formation in the tissues and freeze-avoiding animals which tolerate the low temperatures but not crystallization of the body fluids. The adaptations are mainly directed towards the control or avoidance of ice formation and include the synthesis of low mol. wt cryoprotectants, icenucleating agents and antifreeze proteins. However, some of the adaptations such as the synthesis of low mol. wt cryoprotectants are also more specific in their mechanism, e.g. direct stabilizing interaction with membranes and proteins. The mechanisms employed by such animals may offer ideas and information on alternative approaches which might be usefully employed in the cryopreservation of cells and tissues frequently required in assisted reproductive technology.
The Research of Ear Identification Based On Improved Algorithm of Moment Invariant

In this paper, the processing of ear identification is introduced in brief, and after making an improvement of moment invariants algorithm, six feature vectors are distilled by the method of high-order moment invariants. By using two kinds of algorithm respectively, ear image is processed to identification. In ear identification, we can learn that the high-order moment invariants in the improved algorithm have the feature of invariance in translation, rotation and scale change. Finally, with the application of a BP artificial neutral network to identify 60 ear images, we get a good experiment result of 91.8% accuracy.
Characterizing Communities of Practice in Emerging Science and Technology Fields

Emerging fields in science and technology are of great interest to innovation researchers, but such fields are often difficult to identify and characterize. This paper outlines a system for identifying a key element of emerging fields: their community of practice, consisting of active scientists and researchers. The system does not simply count these human actors and the interactions between them. Rather, guided by actant network theory, it also examines other non-human actors with which they interact, such as organizations, publications and terminologies. Using quantitative indicators inspired by actant network theory, and derived from features extracted from the full text and metadata of scientific publications and patents, the system attempts to identify communities of practice associated with emerging fields in science and technology. This paper outlines details of these features and indicators, describes how these indicators are combined using Bayesian models, and reports the results of applying these indicators to document sets associated with emerging scientific and technological fields. The results reported in this paper show that system outputs generally agree with subject matter expert judgments with respect to determining the existence of communities of practice, and appear to offer interesting insights into the development of emerging fields.
NeuroCGRA: A CGRA with support for neural networks

Today, Coarse Grained Reconfigurable Architectures (CGRAs) are becoming an increasingly popular implementation platform. In real world applications, the CGRAs are required to simultaneously host processing (e.g. Audio/video acquisition) and estimation (e.g. audio/video/image recognition) tasks. For estimation problems, neural networks, promise a higher efficiency than conventional processing. However, most of the existing CGRAs provide no support for neural networks. To realize realize both neural networks and conventional processing on the same platform, this paper presents NeuroCGRA. NeuroCGRA allows the processing elements and the network to dynamically morph into either conventional CGRA or a neural network, depending on the hosted application. We have chosen the DRRA as a vehicle to study the feasibility and overheads of our approach. Synthesis results reveal that the proposed enhancements incur negligible overheads (4.4% area and 9.1% power) compared to the original DRRA cell.
Was comparability overstated for political advantage? (An international comparison of AAS 25: Financial reporting by superannuation plans): WORKING PAPER No. 1998-002

Accounting for superannuation plans remains topical because relevant accountants still have to contend with two conflicting reporting frameworks and because criticism of Australia’s system for regulating its superannuation is continuing. As one device for increasing pressure for the acceptance of AAS 25, the accountancy profession claimed that it is consistent with international accounting standard IAS 26 and is based on best practice. Given that the introduction of AAS 25 was very controversial, there existed an incentive to overstate those claims. This paper reports on a test of the assertion that AAS 25 is consistent with IAS 26, and a test of the assertion that AAS 25 is based on international best practice. Given that the UK and USA are the major influences on Australian accounting practice, the assertions were tested by comparing AAS 25 with IAS 26, FAS 35, and SORP 1, on that basis of 12 criteria. It was found that in a high proportion of instances, significant differences existed. Thus it was concluded that AAS 25 is not consistent with its international, USA or UK counterparts. Accordingly it appears that the claim of consistency may have been overstated for political advantage.
Cryptic Determinant of α4β7 Binding in the V2 Loop of HIV-1 gp120

The peptide segment of the second variable loop of HIV-1 spanning positions 166–181 harbors two functionally important sites. The first, spanning positions 179–181, engages the human α4β7 integrin receptor which is involved in T-cell gut-homing and may play a role in human immunodeficiency virus (HIV)-host cell interactions. The second, at positions 166–178, is a major target of anti-V2 antibodies elicited by the ALVAC/AIDSVAX vaccine used in the RV144 clinical trial. Notably, these two sites are directly adjacent, but do not overlap. Here, we report the identity of a second determinant of α4β7 binding located at positions 170–172 of the V2 loop. This segment – tripeptide QRV170–172– is located within the second site, yet functionally affects the first site. The absence of this segment abrogates α4β7 binding in peptides bearing the same sequence from position 173–185 as the V2 loops of the RV144 vaccines. However, peptides exhibiting V2 loop sequences from heterologous HIV-1 strains that include this QRV170–172 motif bind the α4β7 receptor on cells. Therefore, the peptide segment at positions 166–178 of the V2 loop of HIV-1 viruses appears to harbor a cryptic determinant of α4β7 binding. Prior studies show that the anti-V2 antibody response elicited by the RV144 vaccine, along with immune pressure inferred from a sieve analysis, is directed to this same region of the V2 loop. Accordingly, the anti-V2 antibodies that apparently reduced the risk of infection in the RV144 trial may have functioned by blocking α4β7-mediated HIV-host cell interactions via this cryptic determinant.
On the similarity of tones of the organ stop vox humana to human vowels

In mechanical speech synthesis from the 18th up to the 20th century, reed pipes were mainly used for the generation of the voice and the organ stop vox humana was central in this process. This has been described in different historical documents which report that the vox humana in some organs sounded like human vowels. In this study, tones of four different voces humanae were recorded to investigate their similarity to human vowels. The acoustical and perceptual analysis revealed that some, though not all, tones show a high similarity to selected vowels.
A Survey on Methods and Systems for Graph Compression

We present an informal survey (meant to accompany another paper) on graph compression methods. We focus on lossless methods, briefly list available pproaches, and compare them where possible or give some indicators on their compression ratios. We also mention some relevant results from the field of lossy compression and algorithms specialized for the use on large graphs. --- Note: The comparison is by no means complete. This document is a first draft and will be updated and extended.
Characterizing particle resuspension from mattresses: chamber study.

UNLABELLED People spend approximately one-third of their lives sleeping, where they can be exposed to a myriad of particle-bound biological agents and chemical pollutants that originate within mattresses and bedding, including allergens, fungal spores, bacteria, and particle-phase semi-volatile organic compounds. Full-scale particle resuspension experiments were conducted in an environmental chamber, where volunteers performed a prescribed movement routine on an artificially seeded mattress. Human movements in bed, such as rolling from the prone to supine position, were found to resuspend settled particles, leading to elevations in airborne particle concentrations. Resuspension rates were estimated for the size fractions of 1-2 μm, 2-3 μm, 3-5 μm, 5-10 μm, and 10-20 μm, and were in the range of 10(-3) to 10(1) h(-1). Particle size had the most significant impact on the resuspension rate, whereas dust loading, volunteer body mass, and ventilation rate had a much smaller impact. Resuspension increased with the intensity of a movement, as characterized by surface vibrations, and decreased with repeated movement routines. Inhalation exposure was characterized with the intake fraction metric. Intake fractions increased as the particle size and ventilation rate decreased and ranged from 10(2) to 10(4) inhaled particles per million resuspended, demonstrating that a significant fraction of released particles can be inhaled by sleeping occupants. PRACTICAL IMPLICATIONS Full-scale chamber experiments with human volunteers demonstrate that body movements in bed can resuspend settled particles from mattresses, leading to elevated airborne particle concentrations in both the breathing zone and bulk air of the chamber. Numerous variables influence resuspension, including particle size and intensity of a specific body movement. The results suggest that human-induced resuspension in the sleep microenvironment may play an important role in contributing to our inhalation exposure to mattress dust pollutants.
Key Processes in the Socialization of Student Teachers: Limitations and Consequences of Oversocialized Conceptions of Teacher Socialization.

ABSTRACT . Two differing viewpOinta on the sociallization of student teachers are presented in this review of the literature on ther.subcect. The functionalist view places the Student teacher in a passive role, shaped by childhood experiences, and influenced by peers, pupils, cooperating teacherst'supervisors, and the structure of the school environment. The.opposing view of socilization regards : 'the student teacher as an individual adiustinq to,the school society withott deeP internal changes in beliefs or attitudes. The implications of these opposing philosophies are discussed with questions on the value of the student teaching experience and their implidations for teacher education. A3D1
Comparison of enhancement- and depletion-mode triple stacked power amplifiers in 0.5 µm AlGaAs/GaAs PHEMT technology

This paper describes triple stacked power amplifiers using 0.5 µm enhancement- and depletion-mode (E/D-mode) AlGaAs/GaAs pseudomorphic high electron-mobility transistors (PHEMTs). Based on the optimum capacitance at the gate termination of common-gate (CG) transistor, the output 1-dB compression points (P1dB) of the E- and D-mode triple stacked power amplifiers are 22.1 and 19.3 dBm, respectively. The third-order output intercept point (OIP3) of the E- and D-mode stacked power amplifiers are higher than 32 and 25 dBm, respectively. The E-mode stacked power amplifier demonstrates better output power and linearity as compared with the D-mode stacked power amplifier due to the device characteristics. Moreover, the comparison between the E- and the D-mode tacked power amplifiers is also presented.
Comparative Experiments to Evaluate the Use of Syllables for the Improvement of Automatic Recognition of Dysarthric Speech

In this paper, we propose to use syllables as the acoustic units representing speech signals in an automatic speech recognition (ASR) system in order to improve the performance of the automatic recognition of dysarthric speech. The motivation behind using syllables comes from studies of human perception which demonstrate the central role of the syllable played in human perception and generation of speech. To test our proposed approach, a syllable-based speaker-independent HMM-based ASR system was designed using Hidden Markov Model Toolkit (HTK). A series of experiments on dysarthric speech has been carried out using a subset of NEMOURS database. The obtained results show that the relative improvement in the recognition rate using syllables were found to be 8.18% and 15.48% compared to the recognition rates obtained using monophones and triphones, respectively.
High precision time and frequency counter for mobile applications

This paper presents the design, architecture, operation, and test results of a high precision time interval and frequency counter made as a small, portable instrument with USB interface. Thanks to the use of advanced time interpolators integrated in a CMOS chip, the precision (standard deviation) below 35 ps was obtained at measured time interval from 0 to 200 ms. The frequency can be measured up to 3.5 GHz. Due to the very short dead time of the counter the maximum measurement rate of 5 million measurements per second is achieved. The dedicated control software creates a user-friendly and versatile graphic interface in Windows environment. Reprogrammable CMOS technology used in the counter allows easy customizing of the instrument to match many specific applications.
