Virtual reconstruction of cultural heritage artifacts

Museums and other cultural heritage custodians are interested in digitizing their collections, not only for the sake of preserving cultural heritage, but also to make the information content accessible and affordable to researchers and the general public. Once an objects digital model is created it can be digitally reconstructed to its original uneroded or unbroken shape or realistically visualized using different historical materials. Some artifacts are so fragile that they cannot leave the carefully controlled light, humidity, and temperature of their storage facilities, thus they are already inaccessible to the public, and the viable alternative is their exhibition in the form of an augmented reality scene. We present a sophisticated measurement and processing setup, which we have developed, to enable the construction of physically correct virtual models. This setup is illustrated on the reconstruction of one of the best known Celtic artifact from the European Iron Age period to its original uncorrupted form.
Event Reporting on Continuous Monitoring Wireless Sensor Networks

Wireless Sensor Networks (WSNs) can be typically used to achieve Continuous Monitoring (CM) or Event-Detection inside the supervised area. In CM applications each sensor node transmits periodically its sensed data to the sink node while in Event-Detection Driven (EDD) applications, once an event occurs, it is reported to the sink node by the sensors within the event area. Applications using both continuous monitoring and event driven reporting can also be considered. In this paper, we investigate such hybrid WSNs. Specifically, we propose to reduce the energy consumption by grouping the nodes that sense an event into a separate cluster. By doing so, as it is shown in this paper, the efficiency of the data compression scheme is indeed improved. This event-aware clustering scheme is compared to the case where the event data is transmitted through already established clusters. Finally, the case where sensor nodes only transmit information whenever they sense relevant data is introduced in order to achieve further energy savings.
A novel method reveals that solvent water favors polyproline II over β‐strand conformation in peptides and unfolded proteins: conditional hydrophobic accessible surface area (CHASA)

In aqueous solution, the ensemble of conformations sampled by peptides and unfolded proteins is largely determined by their interaction with water. It has been a long‐standing goal to capture these solute‐water energetics accurately and efficiently in calculations. Historically, accessible surface area (ASA) has been used to estimate these energies, but this method breaks down when applied to amphipathic peptides and proteins. Here we introduce a novel method in which hydrophobic ASA is determined after first positioning water oxygens in hydrogen‐bonded orientations proximate to all accessible peptide/protein backbone N and O atoms. This conditional hydrophobic accessible surface area is termed CHASA. The CHASA method was validated by predicting the polyproline‐II (PII) and β‐strand conformational preferences of non‐proline residues in the coil library (i.e., non‐α‐helix, non‐β‐strand, non‐β‐turn library derived from X‐ray elucidated structures). Further, the method successfully rationalizes the previously unexplained solvation energies in polyalanyl peptides and compares favorably with published experimentally determined PII residue propensities.
Allele and Genotype Frequencies of Cytochrome P450 2B6 Gene in a Mongolian Population

CYP2B6 plays an important role in metabolizing various drugs in common clinical use. Increasing interest in CYP2B6 genetic polymorphism was stimulated by revelations of a specific CYP2B6 genotype significantly affecting the metabolism of efavirenz, an anti-HIV type-1 agent. The present study determined the CYP2B6 haplotype in 100 healthy unrelated Mongolian volunteers by analyzing the genotypes of nine single nucleotide polymorphism (SNP) positions (−82T>C, 64C>T, 499C>T, 516G>T, 777C>A, 785A>G, 983T>C, 1375A>G, and 1459C>T) in the CYP2B6 gene. The CYP2B6 *1 allele was the most frequent in the Mongolian population tested at 64.5%, higher than the equivalent frequency in African-Americans and Ghanaians. The second most frequent allele was CYP2B6 *6 (21.0%), although this allele was less frequent than that in Ghanaians. Only one CYP2B6 *5 allele was identified in our Mongolian subjects (0.5%), although it is the third most frequent allele in white and African-American populations. These CYP2B6 genotypes revealed seven slow efavirenz metabolizers in 100 Mongolians, which is significantly fewer than the same group among Ghanaians. Overall, the Mongolian CYP2B6 allele distribution was comparable with that in Japanese, Koreans, and Han Chinese. This is the first report of CYP2B6 genotype frequency in a Mongolian population, and it could provide clinically useful information on drug metabolism in this population group.
The Changing Relevance of the TLB

A little over a decade ago, Goto and van de Geijn wrote about the importance of the treatment of the translation lookaside buffer (TLB) on the performance of matrix multiplication. Crucially, they did not say how important, nor did they provide results that would allow the reader to make his own judgement. In this paper, we revisit their work and look at the effect on the performance of their algorithm when built with different assumed data TLB sizes. Results on three different processors, one relatively modern, two contemporary with Goto and van de Geijn's writings, are examined and compared within a real-world context. Our findings show that, although important when aiming for a place in the TOP500 list, these features have little practical effect, at least on the architectures we have chosen. We conclude, then, that the importance of the various factors, which must be taken into account when tuning matrix multiplication (GEMM, the heart of the High Performance LINPACK benchmark, and hence of the TOP500 table), differ dramatically relative to one another on different processors.
Decomposing Three Fundamental Matrices for Initializing 3-D Reconstruction from Three Views

This paper focuses on initializing 3-D reconstruction from scratch without any prior scene information. Traditionally, this has been done from two-view matching, which is prone to the degeneracy called “imaginary focal lengths. ” We overcome this difficulty by using three images, but we do not require three-view matching; all we need is three fundamental matrices separately computed from pair-wise image matching. We exploit the redundancy of the three fundamental matrices to optimize the camera parameters and the 3-D structure. The main theme of this paper is to give an analytical procedure for computing the positions and orientations of the three cameras and their internal parameters from three fundamental matrices. The emphasis is on resolving the ambiguity of the solution resulting from the sign indeterminacy of the fundamental matrices. We do numerical simulation to show that imaginary focal lengths are less likely for our three view methods, resulting in higher accuracy than the conventional two-view method. We also test the degeneracy tolerance capability of our method by using endoscopic intestine tract images, for which the camera configuration is almost always nearly degenerate. We demonstrate that our method allows us to obtain more detailed intestine structures than two-view reconstruction and observe how our three-view reconstruction is refined by bundle adjustment. Our method is expected to broaden medical applications of endoscopic images.
Hearing and music in unilateral spatial neglect neuro-rehabilitation

Unilateral spatial neglect (USN) is an attention deficit in the contralesional side of space which occurs after a cerebral stroke, mainly located in the right hemisphere. USN patients are disabled in all daily activities. USN is an important negative prognostic factor of functional recovery and of socio-professional reinsertion. Thus, patient rehabilitation is a major challenge. As this deficit has been described in many sensory modalities (including hearing), many sensory and poly-sensory rehabilitation methods have been proposed to USN patients. They are mainly based on visual, tactile modalities and on motor abilities. However, these methods appear to be quite task-specific and difficult to transfer to functional activities. Very few studies have focused on the hearing modality and even fewer studies have been conducted in music as a way of improving spatial attention. Therefore, more research on such retraining needs is neccessary in order to make reliable conclusions on its efficiency in long-term rehabilitation. Nevertheless, some evidence suggests that music could be a promising tool to enhance spatial attention and to rehabilitate USN patients. In fact, music is a material closely linked to space, involving common anatomical and functional networks. The present paper aims firstly at briefly reviewing the different procedures of sensory retraining proposed in USN, including auditory retraining, and their limits. Secondly, it aims to present the recent scientific evidence that makes music a good candidate for USN patients’ neuro-rehabilitation.
Concept location using formal concept analysis and information retrieval

The article addresses the problem of concept location in source code by proposing an approach that combines Formal Concept Analysis and Information Retrieval. In the proposed approach, Latent Semantic Indexing, an advanced Information Retrieval approach, is used to map textual descriptions of software features or bug reports to relevant parts of the source code, presented as a ranked list of source code elements. Given the ranked list, the approach selects the most relevant attributes from the best ranked documents, clusters the results, and presents them as a concept lattice, generated using Formal Concept Analysis. The approach is evaluated through a large case study on concept location in the source code on six open-source systems, using several hundred features and bugs. The empirical study focuses on the analysis of various configurations of the generated concept lattices and the results indicate that our approach is effective in organizing different concepts and their relationships present in the subset of the search results. In consequence, the proposed concept location method has been shown to outperform a standalone Information Retrieval based concept location technique by reducing the number of irrelevant search results across all the systems and lattice configurations evaluated, potentially reducing the programmers' effort during software maintenance tasks involving concept location.
Understanding the Cultural and Social Impacts on Requirements Engineering Processes Identifying Some Problems Challenging Virtual Team Interaction with Clients

There has been growing interest in virtual teams, and more specifically in virtual software development. Requirements engineering, which is a crucial phase in software development provides another dimension when software development occurs in a virtual domain. While formal software development methods are the obvious first choice for project managers to ensure a virtual software development team remains on track, the social and cultural aspects of requirements engineering cannot be ignored. These social aspects are especially important across different cultures, and have been shown to affect the success of an information system. The discussion in this paper is centred around the requirements engineering processes of a virtual team in a Thai Software House. This paper proposes a framework indicating that project managers need to encourage a balance between formal methods and social aspects in requirements engineering for virtual team members Jo Hanisch, Theerasak Thanasankit, Brian Corbitt
Frequency-shaped sliding mode control for flying height of pickup head in near-field optical disk drives

To achieve stable flying height of a pickup head in near-field optical disk drives, this study investigates a discrete sliding mode control with a frequency-shaped sliding surface. A compensator is introduced in a sliding mode using a frequency-shaped performance index with linear quadratic optimal and sliding mode control. As an actuator, a piezoelectric bender is used in this study to complement an air bearing at the head/disk interface. Experiments are carried out to demonstrate that the proposed controller performs better in flying height control than an optimal sliding mode controller. Accordingly, the controller can achieve stable flying height control in the presence of certain frequency vibration of optical disks.
Coping with Positive and Negative Symptoms of Schizophrenia

Objective: Although coping with positive symptoms of schizophrenia has been studied widely, few studies have examined coping with negative symptoms. This study compares the appraisal of stressfulness and coping patterns in response to positive and negative symptoms experienced by clients with schizophrenia attending a community mental health center. Methods: Clients were interviewed to assess symptom severity, appraisal of symptom stressfulness, and coping strategies used for selected symptoms rated as severe and reported as stressful. Open-ended responses from clients regarding coping strategies were coded according to an a priori coding scheme. Results: Clients reported negative symptoms as less stressful, and they used fewer coping strategies in response than they did for positive symptoms. Clients used some types of coping more than others: behavioral more than cognitive, nonsocial more than social, emotion-focused more than problem-focused, and avoidant more than nonavoidant. Conclusions: Clients more often report positive symptoms as stressful compared with negative symptoms, though negative symptoms are still reported as stressful to a certain degree, indicating a need to improve our ability to help clients cope with negative symptoms. Clients are less likely to use coping strategies to counteract negative symptoms compared with positive symptoms. Implications are discussed for developing interventions tailored to promoting awareness of and ways of coping with negative symptoms.
Is health-related quality of life the same for elderly polish migrants, Turkish migrants and German natives? Testing the reliability and construct validity of the Sf-36 health survey in a cross-cultural comparison

Abstract Objective: The Sf-36 is the most widely used instrument to measure health-related quality of life (HRQoL) with the most convincing evidence of both internal consistency and test–retest reliability. In addition, it is appropriate for use among elderly and minority groups like migrants. The aim of this study is to investigate and compare the reliability and the factorial structure of the Sf-36 in a sample of elderly migrants and natives. The hypothesis is that the construct (the HRQoL consisting of eight dimensions correlated with two components) is the same for elderly Turkish migrants, Polish migrants and German natives. This means that the Sf-36 model shows good psychometric properties and model invariance for the three groups investigated in this study. Methods: The Sf-36 v.2 was forward and backward translated to Turkish and Polish. In this cross-sectional study, interviews were conducted with a sample of elderly migrants from Turkey (n = 100), from Poland (n = 103) and a sample of elderly German natives (n = 101). All data were entered and analysed using SPSS version 21 and AMOS Graphics. Cronbach’s α was used to analyse the reliability of the Sf-36. Multi-group confirmatory factor analysis (MGCFA) and structural equation modelling (SEM) were used for the Sf-36 model invariance testing. Results: The reliability of the Sf-36 was good to excellent for all Sf-36 dimensions (α > 0.7) except for General Health (0.55) in the Polish group. Multi-group confirmatory factor analysis (MGCFA) showed non-invariance between the three groups (CMIN: 180.172, df: 51, CMIN/df: 3.533, p < 0.001, CFI: 0.895, RMSEA: 0.092 for the unconstrained model). Model modifications resulted in a good model fit for the Polish group. However, an applicable common Sf-36 model for the three groups was not attained. Conclusion: This study doesn’t support the idea that the factorial structure of the Sf-36 with two components and eight dimensions is the same across three ethnically and culturally diverse groups of elderly subjects. Therefore, comparing subscale scores of the Sf-36 between different ethnic groups may be problematic.
Is there a crisis in school science education in the UK?

This paper reviews the extent to which contemporary concerns over the recruitment, training and retention of scientists have persisted among science education policy‐makers. Drawing upon key government reports that have been commissioned in order to review the position of science education and training over the last 90 years, we consider the historical context of contemporary “moral panics” about the position of science education in schools. Three themes emerge: the nature and purpose of the school science curriculum, the recruitment of science undergraduates, and the teaching of science in schools. The review suggests that many of the concerns which pre‐occupy us today, such as the perceived “quality” of the science teaching workforce, are the very same that existed when science was first introduced as a school subject. This raises issues about the role of policy in influencing educational change more generally but also questions whether there ever was a “golden age” for science education in the UK.
A Fuzzy Adaptive Hybrid Particle Swarm Optimization Algorithm to Solve Non-Convex Economic Dispatch Problem

— Economic dispatch (ED) plays an important role in power system operation. ED problem is a non-smooth and non-convex problem when valve-point effects, multi-fuel effects and prohibited operating zones (POZs) have been considered. The main objective of economic dispatch is to minimize the total fuel cost while all operating constraints are satisfied. By involving these three constraints the classical PSO faces premature convergence, performance and the diversity loss in optimization process as well as appropriate tuning of its parameters. To handle the problem of premature convergence this paper presents an efficient hybrid evolutionary approach for solving the economic dispatch problem called FAPSO. The algorithm is tested on two typical systems consisting of 6 and 15 thermal units whose incremental fuel cost functions take into account the prohibited operating zones.
Spontaneous emission extraction and Purcell enhancement from thin-film 2-D photonic crystals

Electromagnetic band structure can produce either an enhancement or a suppression of spontaneous emission from two-dimensional (2-D) photonic crystal thin films. We believe that such effects might be important for light emitting diodes. Our experiments were based on thin-film InGaAs-InP 2-D photonic crystals at ambient temperature, but the concepts would apply equally to InGaN thin films, for example. We show that the magnitude of Purcell enhancement factor, F/sub p//spl sim/2, for spatially extended band modes, is similar to that for a tiny mode in a three dimensional (3-D) nanocavity. Nonetheless, light extraction enhancement that arises from Zone folding or Bragg scattering of the photonic bands is probably the more important effect, and an external quantum efficiency >50% is possible. Angle resolved photoluminescence from inside the photonic crystal gives a direct spectral readout of the internal 2-D photonic band dispersion. The tradeoffs for employing various photonic crystal structures in high efficiency light-emitting diodes are analyzed.
Essential Research Findings in Counseling and Psychotherapy

I recently had the opportunity to read Cooper’s book, Essential Research Findings in Counseling and Psychotherapy. The book is written for those professionals who work in thefield of counseling and psychotherapy and is not necessarily limited to socialworkers. Cooper offers a literary work that challenges the long-held conception that the success of psychotherapy is the primary result of the therapist’s theoretical orientation. The book begins by addressing the importance of sound research and critical evaluation in an effort to demonstrate a shift from evidence-based practice to practice-based evidence. The author then undertakes to use research and a variety of research methods to instruct readers on how to critically evaluate, for themselves, statistics that seek to show that one model of psychotherapy has better outcomes at the end of therapy than other models. The reader is encouraged to consider what ultimately is important in terms of the outcomes of the therapy. Is it the overall change in baseline dysfunction that is important or is it something else? The author argues that the research supports variables that are inherent to the therapeutic relationship, over themethodologies for helping our clients, and that the various psychotherapies available are merely a small part of the overall change process. Cooper also offers a discussion and critical analysis of the effects of the therapist’s personality characteristics and style on the change processes. Additionally, the reader is invited to question whether the therapy models themselves cause the greatest change in clients; or is change related to more subtle components found in the manner in which the therapists use the various models in their work and in how they relate to clients. In the end, Cooper suggests that therapists need to stay informed about the research and how this research is applied to the models we use with our clients. He offers practical suggestions for therapists to remain as informed as possible. This book is well written and offers an important alternative perspective in the ongoing debate on efficacy of counseling models. As well, because it offers a practical explanation about how touse research to informpractice, it is an important contribution in support of newsocialwork clinicianswhofind themselves lostwhen trying to ascertain their own individual style and evaluate their own effectiveness. Cooper does not offer an explicit promotion of anti-oppressive practices per se, however; the information he offers in terms of what is important in the therapeutic relationship is a reflection of the very values social workers hold when working with people.
Early-onset sexually harmful behaviour in childhood: a marker for life-course persistent antisocial behaviour?

While traditionally adolescent sexually harmful behaviour (SHB) has been considered beyond the domain of general delinquency, many adolescents showing SHB also show a pattern of non-sexual offending. It was hypothesised that an early onset of SHB would probably reflect the presence of developmental risk factors associated with a generic and persistent antisocial trajectory. A retrospective file review of cases referred to a national SHB service was conducted. Cases were categorised as early onset (n = 100), with SHB evident prior to the age of 10, or late onset (n = 137), with SHB first evident after the age of 10. The early onset group were found to have higher rates of maltreatment, poor temperament, aggression, hyperactivity, educational difficulties, and mental health problems. They also displayed greater continuity of non-sexual antisocial behaviour across childhood and adolescent periods, and scored significantly higher on a standard psychopathy measure. We propose that an early onset of SHB may act as a clinical marker for a group of children at risk of a general delinquency trajectory. These children require early and multifaceted interventions beyond those addressing sexual behaviour problems alone.
