Semi-Automatic Extension of Large-Scale Linguistic Knowledge Bases

Linguistic resources are essential for the success of many AI tasks. Building a new lexical resource from scratch or combining heterogeneous resources is not only complex and time-consuming, but can also lead to knowledge inconsistency and redundancy. In this paper, we present a novel method for the large-scale semantic enrichment of a computational linguistic resource. To this end, with the aid of a controlled vocabulary, we identified a set of representative concepts, i.e. a restricted, but meaningful number of concepts from WordNet, such that each of them can replace any of its descendants in the

A Semiparametric Bayesian Approach to Wiener System Identification

We consider a semiparametric, i.e. a mixed parametric/nonparametric, model of a Wiener system. We use a state-space model for the linear dynamical system and a nonparametric Gaussian process (GP) model for the static nonlinearity. The GP model is a flexible model that can describe different types of nonlinearities while avoiding making strong assumptions such as monotonicity. We derive an inferential method based on recent advances in Monte Carlo statistical methods, known as Particle Markov Chain Monte Carlo (PMCMC). The idea underlying PMCMC is to use a particle filter (PF) to generate a sample state trajectory in a Markov chain Monte Carlo sampler. We use a recently proposed PMCMC sampler, denoted particle Gibbs with backward simulation, which has been shown to be efficient even when we use very few particles in the PF. The resulting method is used in a simulation study to identify two different Wiener systems with non-invertible nonlinearities.
Binding of the Priming Nucleotide in the Initiation of Transcription by T7 RNA Polymerase*

Unlike DNA polymerases, an RNA polymerase must initiate transcription de novo, that is binding of the initiating (+1) nucleoside triphosphate must be achieved without benefit of the cooperative binding energetics of an associated primer. Since a single Watson-Crick base pair is not stable in solution, RNA polymerases might be expected to provide additional stabilizing interactions to facilitate binding and positioning of the initiating (priming) nucleoside triphosphate at position +1. Consistent with base-specific stabilizing interactions, of the 17 T7 RNA polymerase promoters in the phage genome, 15 begin with guanine. In this work, we demonstrate that the purine N-7 is important in the utilization of the initial substrate GTP. The fact that on a template encoding AG as the first two bases in the transcript (as in the remaining two of the T7 genome) transcription starts predominantly (but not exclusively) at the G at position +2 additionally implicates the purine O-6 as an important recognition element in the major groove. Finally, results suggest that these interactions serve primarily to positionthe initiating base in the active site. It is proposed that T7 RNA polymerase interacts directly with the Hoogsteen side of the initial priming GTP (most likely via an interaction with an arginine side chain in the protein) to provide the extra stability required at this unique step in transcription.
Physical Activity and Risk of Recurrence and Mortality in Breast Cancer Survivors: Findings from the LACE Study

Introduction: Identifying modifiable factors that reduce the risk of recurrence and improve survival in breast cancer survivors is a pressing concern. The purpose of this study was to examine the association of physical activity following diagnosis and treatment with the risk of breast cancer recurrence and mortality and all-cause mortality in women with early-stage breast cancer. Materials and Methods: The sample consisted of 1,970 women from the Life After Cancer Epidemiology study, a prospective investigation of behavioral risk factors and health outcomes. Self-reported frequency and duration of work-related, household and caregiving, recreational, and transportation-related activities during the six months prior to enrollment were assessed. Outcomes were ascertained from electronic or paper medical charts. Hazard ratios and 95% confidence intervals were estimated from delayed entry Cox proportional hazards models. Results: Although age-adjusted results suggested that higher levels of physical activity were associated with reduced risk of recurrence and breast cancer mortality (P for trend = 0.05 and 0.07, respectively for highest versus lowest level of hours per week of moderate physical activity), these associations were attenuated after adjustment for prognostic factors and other confounding variables (P for trend = 0.36 and 0.26). In contrast, a statistically significant protective association between physical activity and all-cause mortality remained in multivariable analyses (hazard ratio, 0.66; 95% confidence interval, 0.42-1.03; P for trend = 0.04). Conclusions: These findings do not support a protective effect of physical activity on breast cancer recurrence or mortality but do suggest that regular physical activity is beneficial for breast cancer survivors in terms of total mortality.

Fast and Simple Algorithms for Recognizing Chordal Comparability Graphs and Interval Graphs

In this paper, we present a linear-time algorithm for substitution decomposition on chordal graphs. Based on this result, we develop a linear-time algorithm for transitive orientation on chordal comparability graphs, which reduces the complexity of chordal comparability recognition from O(n2) to O(n+m). We also devise a simple linear-time algorithm for interval graph recognition where no complicated data structure is involved.
Histopathological analysis of the respiratory organs of Channa striata subjected to air exposure

Effects of air exposure on the respiratory organs of Channa striata possessing bimodal respiration for exploitation of water (via gills and skin) as well as air (through air - breathing organs - suprabranchial chamber, ABOs) have been investigated. On air exposure the fish survived for 8 h. Following air exposure the fine, thin-walled blood capillaries (BLCs) at the surface of the ABO swelled and bulged out due to congestion when the blood came very close to air in the lumen. In the initial periods, mucous cells (MCs) of all three respiratory organs showed periodic fluctuations in their density and staining properties and stain for sulphated moieties known to hold an additional quantity of water. The sub-epithelial connective tissues of the ABO and skin also contained a large quantity of sulphated mucopolysaccharides. Subsequently, severe wear and tear and sloughing leading to haemorrhage took place from the skin. The outer cellular layers of the epidermis sloughed off. The density of sacciform-granulated cells (SGCs) increased and stained strongly with PAS technique (almost negative in controls). Air exposure also caused extensive damage in the gills. In the initial periods the BLCs showed severe congestion, causing extensive bulging and protrusion onto the surface. Later, the epithelial linings of gill filaments (PL) as well as respiratory lamellae (SL) were detached and lifted up. Subsequently, the neighbouring SL fused, causing decreased surface area, thereby reducing the efficiency of gills. The ladder-like arrangements of the pillar cells - blood capillaries (PLCs-BLCs) also collapsed. PAS-positive materials appeared within these PLCs. Subsequently, the BLCs dilated and showed congestion. The RBCs of gills also showed PAS staining. A thin layer of sulphated slime often covered the respiratory epithelia. Prior to death of the fish, the cells of the gills degenerated extensively. Thus, air exposure also prevented normal branchial respiration and the fish died due to anoxia and other physiological disorders.

Configuration-level hardware/software partitioning for real-time embedded systems

We present an approach to hardware/software partitioning for real-time embedded systems. The abstraction level we have adopted is referred to as the configuration level, where hardware is modeled as resources with no detailed functionality and software is modeled as tasks utilizing the resources. Through configuration-level analysis, cost and performance tradeoffs can be studied early in the design process and a large design space can be explored. Feasibility factor is introduced to measure the possibility of a real-time system being feasible, and is used as both a constraint and an attribute during the optimization process. Optimal partitioning is achieved through the use of an existing computer-aided design tool. <<ETX>>
Factors affecting the adoption of faculty-developed academic software: A study of five iCampus projects

Instruction in higher education must adapt more rapidly to: changes in workforce needs, global issues, advances in disciplines, and resource constraints. The pace of such improvement depends on the speed with which new ideas and materials are adopted across institutions. In 1999 Microsoft pledged $25 million and staff support for iCampus, a seven-year MIT project to develop pioneering uses of educational technology. The TLT Group studied five iCampus projects in order to identify factors affecting institutionalization and widespread dissemination. Among the factors impeding adoption: lack of rewards and support for faculty to adopt innovations; faculty isolation; and a lack of attention to adoption issues among projects selected for funding. The study made recommendations for universities, foundations, government agencies and corporations: 1) continue making education more authentic, active, collaborative, and feedback-rich; 2) create demand to adopt ideas and materials from other sources by encouraging all faculty members to improve and document learning in their programs, year after year; 3) nurture coalitions for instructional improvement, across and within institutions; 4) create more effective higher education - corporate alliances; and 5) improve institutional services to support faculty in educational design, software development, assessment methods, formative evaluation, and/or in sharing ideas with others who teach comparable courses.
Physical conditions in quasi-stellar object absorbers from fine-structure absorption lines

We calculate theoretical population ratios of the ground fine-structure levels of some atoms/ions which typically exhibit ultraviolet (UV) lines in the spectra of quasi-stellar objects (QSO) absorbers redward the Lya forest: C°, C + , O 0 , Si + and Fe + . The most reliable atomic data available are employed and a variety of excitation mechanisms are considered: collisions with several particles in the medium, direct excitation by photons from the cosmic microwave background radiation (CMBR) and fluorescence induced by a UV field present. The theoretical population ratios are compared with the corresponding column density ratios of C I and CII lines observed in damped Lya (DLA) and Lyman Limit (LL) systems, collected in the recent literature, to infer their physical conditions. The volumetric density of neutral hydrogen in DLA systems is constrained to be lower than tens of cm - 3 (or a few cm - 3 in the best cases), and upper limits to the UV radiation field intensities to be about two orders of magnitude bigger than the radiation field of the Galaxy (one order of magnitude in the best cases). Their characteristic sizes are higher than a few pc (tens of pc in the best cases) and lower limits for their total masses vary from 10° to 10 5 solar masses. For the only LL system in our sample, the electronic density is constrained to be n e < 0.15 cm - 3 . We suggest that the fine-structure lines may be used to discriminate between the current accepted picture of the UV extragalactic background as the source of ionization in these systems and a local origin for the ionizing radiation as supported by some authors. We also investigate the validity of the temperature-redshift relation of the CMBR predicted by the standard model and study the case for alternative models.
Behavioural facial animation using motion graphs and mind maps

We present a new behavioural animation method that combines motion graphs for synthesis of animation and mind maps as behaviour controllers for the choice of motions, significantly reducing the cost of animating secondary characters. Motion graphs are created for each facial region from the analysis of a motion database, while synthesis occurs by minimizing the path distance that connects automatically chosen nodes. A Mind map is a hierarchical graph built on top of the motion graphs, where the user visually chooses how a stimulus affects the character's mood, which in turn will trigger motion synthesis. Different personality traits add more emotional complexity to the chosen reactions. Combining behaviour simulation and procedural animation leads to more emphatic and autonomous characters that react differently in each interaction, shifting the task of animating a character to one of defining its behaviour.
Ensuring an independent future for young people with special educational needs and disabilities (SEND): a critical examination of the impact of education, health and care plans in England

ABSTRACT This article examines the implications of the new education, health and care (EHC) planning process for career professionals in England. The new process comes in the wake of a succession of legislation relating to young people with special educational needs and disabilities (SEND) in England. There is much to recommend the new process as it represents a shift to a more holistic and person-centred approach. However, there are four main criticisms which can be made of the new process: (1) the policy has an excessive focus on paid work as an outcome which is unrealistic (for some young people); (2) the resourcing in local authorities is too limited to successfully operationalise the policy; (3) there is a lack of clarity about the professional base delivering EHC planning (especially in relation to the career elements); and (4) the policy is too narrowly targeted. While the new legislation offers some major opportunities, realising these will be difficult. In this paper, questions are raised about the resources required to deliver these services; the responsibilities relevant to such services; and the role and scope of these services in supporting the transitions of vulnerable young people into learning and work in an environment where universal careers provision has been substantially diminished.
Automatic City Region Analysis for Urban Routing

There are different functional regions in cities such as tourist attractions, shopping centers, workplaces and residential places. The human mobility patterns for different functional regions are different, e.g., people usually go to work during daytime on weekdays, and visit shopping centers after work. In this paper, we analyse urban human mobility patterns and infer the functions of the regions in three cities. The analysis is based on three large taxi GPS datasets in Rome, San Francisco and Beijing containing 21 million, 11 million and 17 million GPS points respectively. We categorized the city regions into four kinds of places, work-places, entertainment places, residential places and other places. First, we provide a new quad-tree region division method based on the taxi visits. Second, we use the association rule to infer the functional regions in these three cities according to temporal human mobility patterns. Third, we show that these identified functional regions can help us delivering data in network applications, such as urban Delay Tolerant Networks (DTNs), more efficiently. The new functional-regions-based DTNs algorithm achieves up to 183% improvement in terms of delivery ratio.
Fair QoS resource management and non-linear prediction of 3D rendering applications

Resource management in a grid has to able to guarantee commercial or industrial applications a personalized quality of service (QoS). To implement, however, an efficient resource allocation scheme, prediction of task workload is required. In this paper, we present an efficient algorithm for predicting the workload of 3D rendering tasks based on constructive neural network architecture. We also consider the QoS scheduling problem whose target is to determine when and on which resource a given job should be executed. We propose an algorithm for QoS scheduling, which allocates the resources in a fair way, and we compare it to other scheduling schemes such as the earliest deadline first and the first come first serve policies.
HER2-Specific T Cells Target Primary Glioblastoma Stem Cells and Induce Regression of Autologous Experimental Tumors

Purpose: Glioblastoma multiforme (GBM) is the most aggressive human primary brain tumor and is currently incurable. Immunotherapies have the potential to target GBM stem cells, which are resistant to conventional therapies. Human epidermal growth factor receptor 2 (HER2) is a validated immunotherapy target, and we determined if HER2-specific T cells can be generated from GBM patients that will target autologous HER2-positive GBMs and their CD133-positive stem cell compartment. Experimental Design: HER2-specific T cells from 10 consecutive GBM patients were generated by transduction with a retroviral vector encoding a HER2-specific chimeric antigen receptor. The effector function of HER2-specific T cells against autologous GBM cells, including CD133-positive stem cells, was evaluated in vitro and in an orthotopic murine xenograft model. Results: Stimulation of HER2-specific T cells with HER2-positive autologous GBM cells resulted in T-cell proliferation and secretion of IFN-γ and interleukin-2 in a HER2-dependent manner. Patients' HER2-specific T cells killed CD133-positive and CD133-negative cells derived from primary HER2-positive GBMs, whereas HER2-negative tumor cells were not killed. Injection of HER2-specific T cells induced sustained regression of autologous GBM xenografts established in the brain of severe combined immunodeficient mice. Conclusions: Gene transfer allows the reliable generation of HER2-specific T cells from GBM patients, which have potent antitumor activity against autologous HER2-positive tumors including their putative stem cells. Hence, the adoptive transfer of HER2-redirected T cells may be a promising immunotherapeutic approach for GBM. Clin Cancer Res; 16(2); 474–85
Se p 20 03 Quiver Mechanics for Deconstructed Matrix String

In this paper we propose a quiver model of matrix quantum mechanics with 8 supercharges which, on a Higgs branch, deconstructs the worldsheet of Matrix String Theory. This discrete model evades the fermion doubling problem and, in the continuum limit, enhances the number of supersymmetries to sixteen. Our model is motivated by orbifolding the Matrix Model, and the deconstruction ansatz exhibits a duality between target space compactification and worldsheet deconstruction.
$Q$-Band Spatially Combined Power Amplifier Arrays in 45-nm CMOS SOI

This paper reports 45-GHz power amplifier (PA) arrays implemented in 45-nm CMOS silicon-on-insulator, coupled to antenna arrays to enable free-space power combining. A single CMOS chip (2.5 × 4.5 mm2) containing eight-unit PAs was developed and its output was fed to a 2 × 2 array of differentially fed patch antennas on a printed circuit board. This array provided an equivalent isotropic radiated power (EIRP) of 40 dBm at 45 GHz with 28 dBm of total RF power generated by the chip. A larger array, composed of four CMOS chips and feeding a 2 × 8 array of antennas, was shown to deliver an EIRP of 50 dBm at 45 GHz, while generating a total RF power of 33 dBm together with an antenna array gain of 17 dB. The dc power consumptions for the 2 × 2 and the 2 × 8 arrays were 4.9 and 18 W, respectively, with estimated peak power-added efficiencies of 13.5% and 10.7%.
Migraine and Antiphospholipid Antibodies: No Association Found in Migraine-Discordant Monozygotic Twins

Migraine headache (with and without aura) is common in the general population and is known to be influenced by genetic factors with heritability estimates between 34-57±. Antiphospholipid syndrome (APS) is a hypercoagulable state characterized by clinical features including venous and arterial thromboses, pregnancy loss and migraine, and by association with antiphospholipid antibodies (aPL). Numerous small studies have investigated whether aPL are associated with migraine in the general population—-with contradictory results. In this study, the question was addressed by studying the prevalence of aPL in members of monozygotic (MZ) twin pairs differing in their migraine status. Such twins provide a unique natural experiment, matched as they are for age, sex and genetic factors, and allow the role of environmental factors, such as aPL, to be determined. Despite 95± power to detect a difference of 0.59 IgG units per litre in anticardiolipin antibody IgG titres, no difference in prevalence of aPL could be detected in migraine-discordant MZ twins.
Adding modal operators to the action language A

Proceedings of the International Workshop on Non-Monotonic Reasoning (NMR-04) in Whistler, BC, 2004. The action language A is a simple high-level language for describing transition systems. In this paper, we extend the action language A by allowing a unary modal operator in the underlying propositional logic. The extended language requires very little new machinery, and it is suitable for describing transitions between Kripke structures. We consider some formal restrictions on action descriptions that preserve natural classes of Kripke structures, and we prove that the modal epistemic extension of A naturally subsumes related approaches to reasoning about knowledge. We conclude with some plans for future work. Introduction The action language A is a simple high-level language for reasoning about the effects of actions (Gelfond & Lifschitz 1993). The basic language is suitable only for simple action domains, but it has been extended several times to address a wide range of problems (Baral & Gelfond 1997; Baral, Gelfond, & Provetti 1997). In this paper, we suggest that it is possible to increase the representational power of A without changing the action language itself. Instead, we look at extending the underlying propositional logic by adding modal operators. We consider the expressive power of the modal extension, and compare the framework with related work on epistemic extensions of A.
