A segmentation-based approach for detection of stiction in control valves

A method for detecting static friction (stiction) in control valves is proposed. The method is model-based and is inspired by ideas from the fields of change detection and multi-model mode estimation. Opposed to existing methods only limited process knowledge is needed and it is not required that the loop has oscillating behavior. The advantage of the method is illustrated in both numerical simulations and evaluations on real loop data.
A smart current modulation scheme for harmonic reduction in three-phase motor drive applications

Electric motor-driven systems consume considerable amount of the global electricity. Majority of three-phase motor drives are equipped with conventional diode rectifier and passive harmonic mitigation, being witnessed as the main source in generating input current harmonics. While many active harmonic mitigation methods have been developed over the years, the total cost and complexity has become the main obstacle in employing prior-art methods for motor drive systems. This paper presents a novel current modulation method based on the electronic inductor concept for three-phase ac-dc systems to reduce input current harmonics. The obtained results at simulation and experimental levels confirm the effectiveness of the proposed approach.
Classification of gastric carcinoma using the Goseki system provides prognostic information additional to TNM staging

Due to the high variability of the epidemiology, genetics, morphology, and biologic behavior of gastric carcinoma, many classification systems are in use, e.g., the World Health Organization (WHO) classification; tumor differentiation; the criteria of Ming, Mulligan, and Laurén; and the recently introduced Goseki classification. In the authors' opinion, the TNM staging is the most valuable classification system, with a prognostic value for survival.
Candidate Genes Associated With Malignant Pheochromocytomas by Genome-Wide Expression Profiling

Objective:To improve our understanding of the molecular mechanisms involved in malignant pheochromocytoma by examining differences in the gene expression profile between benign and malignant tumors. Background:The molecular events involved in the malignant transformation of pheochromocytoma are poorly understood. There are also no reliable and uniformly accepted histopathologic criteria to distinguish benign from malignant pheochromocytoma. Methods:We performed genome-wide expression profiling of 58 pheochromocytomas (29 benign and sporadic, 16 benign and hereditary, 13 malignant) with technical and biologic replication. Results:Unsupervised cluster analysis showed 3 main clusters of tumors that did not have complete concordance with the clinical and pathologic groupings of pheochromocytomas. Supervised cluster analysis showed almost completely separate clustering between benign and malignant tumors. The differentially expressed genes with known function belonged to 8 biologic process categories; signal transduction, transcription, protein transport, protein synthesis, smooth muscle contraction, ion transport, chemotaxis, and electron transport. Gene set enrichment analysis revealed significant correlation between the microarray profiles of malignant pheochromocytomas and several known molecular pathways associated with carcinogenesis and dedifferentiation. Ten differentially expressed genes had high diagnostic accuracy, and 5 of these genes (CFC1, FAM62B, HOMER1, LRRN3, TBX3, ADAMTS) in combination had an area under the receiver operating characteristic (ROC) curve of 0.96 for distinguishing benign versus malignant tumors. Conclusions:Differentially expressed genes between benign and malignant pheochromocytomas distinguish between these tumors with high diagnostic accuracy. Our findings provide new insight into the genes and molecular pathways that may be involved in malignant pheochromocytomas.
FACE RECOGNITION IN SECURITY APPLICATIONS

During last two decades, the field of biometric person recognition has undergone significant progress. Next-generation human-communication system interfaces will incorporate biometric person recognition, using face, iris, speech, video and other behavior signals to provide more user friendly, efficient and safer communication operation, as well as secure communication. Biometric person recognition in all systems, like communication systems or automatic driving systems, especially represent a challenge for researchers because of difficulties posed by involvement methods and identification parameters of person under recognition process. In this article, we present an overview person recognition technologies. We also present that the levels of accuracy required for person recognition can be achieved only by fusing multiple modalities. In the paper we discuss also about possible methods and techniques for major biometric parameters recognition
Research on Organization and Discovery of Grid Resources

This paper analyzes grid resources organization, elaborates on the fundamental principles of the ant colony algorithm, and proposes a grid resource discovery method based on the ant colony algorithm. We consider users request ontology as ants, take search resource as food, and food source is the node of search target. The process of ants to find food is similar to the process of discovery grid resources.
The diagnosis of depression in disorder.

Objective: My purpose is to critically evaluate psychiatry's current approach to the diagnosis of depression.Methods: I have closely examined trends in diagnosing depression, especially since DSM-III, and have considered alternative options.Results/Conclusions: Psychiatric taxonomy is currently based on invalid nosological premises that have worked as a straitjacket for conceptual progress and related biological and psychopharmacological research. A fresh approach that replaces nosological analysis with the concepts of functionalisation and verticalisation is essential.
Learning Styles measurement: a cause for concern

Not one of the inventories that have been found have a current good reputation in the prime source for the evaluation of psychometric devices – The Mental Measurement Yearbook. Most have very poor reporting of reliability. There is little information on item characteristics including the definition of the basic measurement space that they cover. At best there is information on construct validity with very little on outcome or predictive validity.
Integrating Soft Robotics with the Robot Operating System: A Hybrid Pick and Place Arm

Soft robotic systems present a variety of new opportunities for solving complex problems. The use of soft robotic grippers, for example, can simplify the complexity in tasks such as the grasping of irregular and delicate objects. Adoption of soft robotics by the Informatics community and industry, however, has been slow and this is, in-part, due to the amount of hardware and software that must be developed from scratch for each use of soft system components. In this paper we detail the design, fabrication and validation of an open-source framework that we designed to lower the barrier to entry for integrating soft robotic subsystems. This framework is built on ROS (the Robot Operating System) and we use it to demonstrate a modular, soft-hard hybrid system which is capable of completing pick and place tasks. By lowering this barrier to entry through our open sourced hardware and software we hope that system designers and Informatics researchers will find it easy to integrate soft components into their existing ROS-enabled robotic systems.
Use of Immunohistochemistry in Diagnosis of Breast Epithelial Lesions

In recent years, the use of immunohistochemistry (IHC) in breast pathology has increased tremendously. It is not because the new genre of breast pathologists are less well trained than their “experienced” counterparts; it is mainly because of the demands of more accurate and precise diagnoses, identification of new entities and availability of novel antibodies. The main purpose of this review is to discuss the use of best available antibodies in diagnoses of breast epithelial lesions. The following items are discussed: assessment of invasion, IHC in papillary lesions, identification of breast tumor subtypes, IHC in proliferative breast lesions, assessment of lymphatic space invasion, diagnosis of metaplastic breast carcinoma, IHC in Paget disease, use of cytokeratins in sentinel lymph node assessment, and diagnosis of breast carcinoma at metastatic sites. Because the main focus of this review is on diagnosis, receptor studies on breast carcinoma are briefly discussed and only a few general comments are made.
Modeling the effect of high dead-space syringes on the human immunodeficiency virus (HIV) epidemic among injecting drug users.

AIMS To illustrate the impact of different proportions of injecting drug users (IDUs) sharing high dead-space syringes (HDSS) or low dead-space syringes (LDSS) on the probability of human immunodeficiency virus (HIV) transmission; and thus the impact on injection-related HIV prevalence and incidence. DESIGN A stochastic mathematical model was used to evaluate the impact of HDSS use in high- and low-risk IDU populations. Model parameters were obtained from peer-reviewed publications. Analytical solutions of a simplified deterministic model were obtained to explain the effect of HDSS on HIV endemic states. FINDINGS Simulation analysis shows that the HIV epidemic could be sustained even when a small percentage of sharing (10%) involved HDSS. The effect is much stronger in high-risk compared with low-risk populations. Steady state HIV prevalence increases with the proportion of HDSS, and for high- and low-risk populations reaches around 80% and 20%, respectively. For low-risk populations, the use of LDSS could result in the virtual elimination of HIV. These results are dependent upon an evidence-supported assumption of a significant difference in HIV transmission risk associated with HDSS versus LDSS. CONCLUSIONS Our models suggest that injection-related HIV epidemics may not occur when most (e.g. 95% or more) IDUs use LDSS. While these results are based on indirect risk measures and a number of simplifying assumptions, the effect of blood retained in high dead-space syringes on HIV prevalence seems to be very strong, even using relatively conservative assumptions. The findings have potential implications for needle exchange programs and the types of syringes produced and distributed world-wide.
A Concrete Chinese NLP Pipeline

Natural language processing research increasingly relies on the output of a variety of syntactic and semantic analytics. Yet integrating output from multiple analytics into a single framework can be time consuming and slow research progress. We present a CONCRETE Chinese NLP Pipeline: an NLP stack built using a series of open source systems integrated based on the CONCRETE data schema. Our pipeline includes data ingest, word segmentation, part of speech tagging, parsing, named entity recognition, relation extraction and cross document coreference resolution. Additionally, we integrate a tool for visualizing these annotations as well as allowing for the manual annotation of new data. We release our pipeline to the research community to facilitate work on Chinese language tasks that require rich linguistic annotations.
Complex event types for agent-based simulation

This thesis presents a novel formal modelling language, complex event types (CETs), to describe behaviours in agent-based simulations. CETs are able to describe behaviours at any computationally represented level of abstraction. Behaviours can be specified both in terms of the state transition rules of the agent-based model that generate them and in terms of the state transition structures themselves. Based on CETs, novel computational statistical methods are introduced which allow statistical dependencies between behaviours at different levels to be established. Different dependencies formalise different probabilistic causal relations and Complex Systems constructs such as ‘emergence’ and ‘autopoiesis’. Explicit links are also made between the different types of CET inter-dependency and the theoretical assumptions they represent. With the novel computational statistical methods, three categories of model can be validated and discovered: (i) inter-level models, which define probabilistic dependencies between behaviours at different levels; (ii) multi-level models, which define the set of simulations for which an inter-level model holds; (iii) inferred predictive models, which define latent relationships between behaviours at different levels. The CET modelling language and computational statistical methods are then applied to a novel agent-based model of Colonic Cancer to demonstrate their applicability to Complex Systems sciences such as Systems Biology. This proof of principle model provides a framework for further development of a detailed integrative model of the system, which can progressively incorporate biological data from different levels and scales as these become available.
GROUP AND INDIVIDUAL TREATMENT OF COMPULSIVE HOARDING: A PILOT STUDY

Treatment of compulsive hoarding has rarely been described in the literature, apart from standard treatments for obsessive compulsive disorder of which hoarding is thought to be a subset. This paper presents preliminary findings from seven patients treated with cognitive and behavioral interventions derived from Frost and Hartl's (1996) theoretical model of hoarding. Six clients attended 15 group treatment sessions over 20 weeks plus individual home treatment sessions and one client received 20 weekly-sessions of individual treatment only. After 20 weeks, treatment resulted in noticeable improvement in several hoarding symptoms for five of the seven patients, especially reduction in excessive acquisition of possessions, although problems with clutter persisted. Three of four clients who continued in treatment for approximately 1 year showed substantial further improvement, although none felt entirely recovered. Findings are discussed in light of the model of hoarding and possible modifications to treatment to enhance motivation and benefits.
Feasibility and outcome of dialogical exposure therapy for posttraumatic stress disorder: A pilot study with 25 outpatients

Abstract Objective: The research on psychotherapy for posttraumatic stress disorder (PTSD) stems predominantly from a cognitive-behavioral orientation while other approaches are underrepresented. We evaluated dialogical exposure in trauma therapy (DET), a treatment for PTSD combining cognitive-behavioral elements with an interpersonal, gestalt-based framework. Methods: In this uncontrolled pilot trial, 25 PTSD patients were treated with DET in an outpatient setting and 21 completed therapy. Results: There was a significant reduction in self-rated PTSD symptoms from pre- to posttreatment. Effect sizes were large in the completer sample and moderate to large in the intent-to-treat sample. General psychopathology also decreased significantly. The dropout rate was rather low at 16%. Conclusion: These results show that further research on DET as a treatment for PTSD is warranted.
Dataflow Programming with Intel Concurrent Collections Instructor :

The Concurrent Collections (CnC) model was developed to address the need for making parallel programming accessible to domain experts or non-professional programmers. One approach that has historically addressed this problem is the creation of domain specific languages (DSLs), such as Matlab, R, SQL, and Google’s MapReduce framework that hide the details of parallelism when programming for a specific application domain. In contrast, CnC is a model for adding parallelism to a sequential language using primitives that should be accessible to people who are not Computer Science majors.
Prevalence of the Y165C, G382D and 1395delGGA germline mutations of the MYH gene in Italian patients with adenomatous polyposis coli and colorectal adenomas

Biallelic germline mutations in the base excision repair gene MYH have been reported in patients with multiple colorectal adenomas and cancer and in sporadic FAP patients not showing a detectable APC germline mutation. In this study, the prevalence of the common Y165C and G382D germline variants of the MYH gene was examined in 70 FAP/AAPC patients with no detectable APC mutation and a family history compatible with recessive inheritance. In addition, 141 normal‐population adenoma patients (mean number of adenomas, 2.8; range, 1–9) and 52 clean colon controls were studied. The entire coding region of the MYH gene was analyzed in Y165C or G382D heterozygous patients. Since the same second mutational event (a 3 bp deletion in exon 14, 1395delGGA) was detected in 3 patients, the prevalence of this variant was also examined in all groups. In all, 14 of 70 patients in the FAP/AAPC group (20%; 95% CI = 11.7–31.6%) had biallelic germline MYH variants and 3 were heterozygotes (4.3%). None of the 141 normal‐population adenoma patients carried biallelic germline MYH variants (95% CI = 0.06–4.1%) and 3 were heterozygotes (2.1%). In the control group, no MYH variants were detected. These results indicated that MYH‐associated polyposis (MAP) is present in about 20% of Italian FAP/AAPC patients, in whom no germline APC mutation is detectable and showing a family history compatible with recessive inheritance, and in a small fraction of patients with colorectal adenomas in the general population. In addition, our data suggest that mutation 1395delGGA is a subpolymorphic MYH mutational event in some Caucasian populations. © 2004 Wiley‐Liss, Inc.
Opening spaces of academic culture: doors of perception; heaven and hell

ABSTRACT Academic culture is a distinct and unique field, and perhaps may best be conceptualised as a space. Although access to university has traditionally been restricted, recent efforts on a number of fronts have attempted to ‘open’ the space of the academy. In particular, enabling programmes such as Preparatory Programs and Foundation Courses aim to provide both access and enabling experiences to students who have found the doors of the university closed to them. The research reported here combined a Bourdieuian framework with a phenomenological methodology to explore the lived experience of students who were most of the way through such a programme at a Go8 Australian university. Thirteen students were interviewed and the data were analysed for experiences of enculturation and positive transformation, as well as alienation and negative transformation. The results showed that while in general the students are able to adopt the habitus of academic culture this was a painful and difficult process, and not entirely successful in all cases. This, combined with the inherent limitations of much research of this kind, gives us reason to pause in the overarching story of social mobility that usually surrounds these types of programmes.
What Typically Developing Children’s Parents Say When They Read Books About Disabilities

The purpose of this study was to examine (a) how parents and their kindergarten-age children talk about disabilities when they read books that include characters with disabilities and (b) the relationship between the frequency of mother/child comments about disabilities and children’s attitudes toward peers with disabilities, as measured by the Acceptance Scale for Kindergarten–Revised (ASK-R). Thirteen mothers and their children audiotaped their conversations when they read books that included characters with disabilities. Seventy conversations were analyzed and 12 themes were identified. The themes that appeared most frequently in the mother–child conversations about disabilities included differences in abilities and similarities between the child and the book characters with disabilities. Although the relationship between the number of words spoken by the parent–child dyads and children’s attitudes toward peers with disabilities was not statistically significant, group differences between the number of words spoken and the content of the disability-related conversations were observed.

Investigating validity from teachers' perspectives through their engagement in large-scale assessment: The Emergent Literacy Baseline Assessment project

This paper argues for an expanded conception of test validity, in which teachers, as end-users of tests, contribute a distinctive perspective on validity, referred to as inferential validity. It also offers a methodology that could be adopted in order to subject this dimension of validity to scrutiny. An investigation conducted into the meanings constructed by teachers of a literacy test, the Emergent Literacy Baseline Assessment (ELBA), is reported to illustrate the methodology. In the first section of the paper, current conceptions of validity are discussed. It is argued that the validation process for tests should include the clarification and justification of the interpretations and uses of observed scores. This argument is illustrated from the methodology for investigating the validity of the ELBA. Self-assessment questionnaires and focus-group interviews provided data on teachers' views about the validity of the ELBA. Arguments in favour of investigating the validity of large-scale tests by taking into account teachers' perspectives are provided.
Evaluation of indicators of cobalamin deficiency defined as cobalamin-induced reduction in increased serum methylmalonic acid.

BACKGROUND Early detection of cobalamin deficiency is clinically important, and there is evidence that such deficiency occurs more frequently than previously anticipated. However, serum cobalamin and other commonly used tests have limited ability to diagnose a deficiency state. METHODS We investigated the ability of hematological variables, serum cobalamin, plasma total homocysteine (tHcy), serum and erythrocyte folate, gastroscopy, age, and gender to predict cobalamin deficiency. Patients (n = 196; age range, 17-87 years) who had been referred from general practice for determination of serum cobalamin were studied. Cobalamin deficiency was defined as serum methylmalonic acid (MMA) >0.26 micromol/L with at least 50% reduction after cobalamin supplementation. ROC and logistic regression analyses were used. RESULTS Serum cobalamin and tHcy were the best predictors, with areas under the ROC curve (SE) of 0. 810 (0.034) and 0.768 (0.037), respectively, but age, intrinsic factor antibodies, and gastroscopy gave additional information. CONCLUSIONS When cobalamin deficiency is suspected in general practice, serum cobalamin should be the first diagnostic test, and the result should be interpreted in relation to the age of the patient. When a definite diagnosis cannot be reached, MMA and tHcy determination will provide additional discriminative information, but MMA, being more specific, is preferable for assessment of cobalamin status.
