Visualizing Repertory Grid Data for Formative Assessment

Repertory grid tools systematically collect data that consists of a topic, its elements, constructs and element ratings. Gaining meaningful insights from repertory grids data is a challenge because data analysis is timeconsuming and a significant mental effort is needed. Visualizations aim at facilitating data analysis through a visual and interactive approach, which allows users to understand their data, reflect, and make better decisions. This paper presents an interactive visualization tool for teachers and students. The tool visualizes repertory grid data using two dashboards, where teachers and students can investigate constructs and rating elements of students at the individual or group level. Visualizing the repertory grid data is an initial attempt towards teaching analytics. Future work will focus on evaluating the tool in a real setting with teachers and students, and collecting suggestions for improvement.
Structural Integrity Assessment of Thin‐Walled Structures

As part of the concept of damage tolerant design, methods for the analytical and numerical simulation of ductile crack extension in thin‐walled structures are presented and discussed. They comprise the application of an analytical flaw assessment procedure as well as finite element analyses based on the crack tip opening displacement (CTOD), δ5, and finite element simulations of crack extension based on the crack tip opening angle (CTOA), a cohesive zone model and a ductile damage model. All these methods are or will become part of the GKSS Structural Integrity Assessment Method (SIAM), which also provides test procedures for the experimental determination of the required material parameters.
Visualization of magnetic dipolar interaction based on scanning transmission X-ray microscopy

Using scanning transmission X-ray microscopy (STXM), in this report we visualized the magnetic dipolar interactions in nanocrystalline Nd-Fe-B magnets and imaged their magnetization distributions at various applied fields. We calculated the magnetic dipolar interaction by analyzing the interaction between the magnetization at each point and those at the other points on the STXM image.
Applying Little-JIL to describe Process-Agent knowledge and support project planning in SoftPM

SoftPM is a toolkit that supports a process-based approach to software project management. It relies upon a software process modeling method based upon the idea of an Organization-Entity to define standard processes and model project processes. The Process-Agent is the core of this modeling method and is a well-defined unit whose role is to encapsulate an Organization-Entity's knowledge, skill etc. The Process-Agent's infrastructure comprises descriptive knowledge, process knowledge and an experience library. The process knowledge is represented by process steps, whose execution determines the behaviors of the Process-Agent. This causes Process-Agent knowledge to be precisely described and well organized. In this paper, Little-JIL, a well-known process modeling language, is used to define a Process-Agent's process knowledge. Benefits for process element knowledge representation arising from Little-JIL's simplicity, semantic richness, expressiveness, formal and precise yet graphical syntax etc., are described. The article also demonstrates how this knowledge can be useful in supporting project planning activities, such as time estimation. Copyright © 2007 John Wiley & Sons, Ltd.
Effect of opsonophagocytosis mediated by specific antibodies on the co-amoxiclav serum bactericidal activity against Streptococcus pneumoniae after administration of a single oral dose of pharmacokinetically enhanced 2000/125 mg co-amoxiclav to healthy volunteers.

OBJECTIVES To measure the effect of opsonophagocytosis mediated by complement activated by specific antibodies on the co-amoxiclav serum bactericidal activity against Streptococcus pneumoniae strains with reduced susceptibility to beta-lactams (amoxicillin MICs of 2, 4, 8 and 16 mg/L). METHODS An open Phase I study measuring ex vivo bactericidal activity after anti-pneumococcal vaccination and an oral dose of 2000/125 mg sustained-release co-amoxiclav was carried out. The ex vivo bactericidal activity was investigated through killing curves over 3 h [assuring polymorphonuclear neutrophil (PMN) viability] with serum samples collected 1.5 h and 5 h after dosing. Global killing was measured as the area under the killing curve (AUKC; log cfu x h/mL). The AUKC of the control growth curve of S. pneumoniae in Hanks' balanced salt solution (AUKC(K)) was used as control. The effect of the presence of complement and/or PMN was evaluated by the difference in the AUKC(K) and the different AUKCs obtained in the presence of inactivated serum (AUKC(IS)), active serum (AUKC(S)), inactivated serum plus PMN (AUKC(IS+PMN)) and active serum plus PMN (AUKC(S+PMN)). RESULTS Significant differences were found in all cases between the bactericidal activity of active serum+PMN (AUKC(K) - AUKC(S+PMN)) and that of inactivated serum (AUKC(K) - AUKC(IS)) with therapeutic indexes ranging from 0.56 to 3.04. At 1.5 h after dosing, a significantly higher bactericidal activity of co-amoxiclav was obtained when opsonophagocytosis occurred (samples with active serum and PMN) than when not occurring (killing curves with inactivated serum and without PMN), for all amoxicillin non-susceptible strains. CONCLUSIONS The results of this ex vivo study suggest that the collaboration of co-amoxiclav and complement-mediated opsonophagocytosis activated by specific antibodies may lay new approaches to overcome in vivo amoxicillin non-susceptibility.
Allosteric Regulation of Mammalian Pantothenate Kinase*

Pantothenate kinase is the master regulator of CoA biosynthesis and is feedback-inhibited by acetyl-CoA. Comparison of the human PANK3·acetyl-CoA complex to the structures of PANK3 in four catalytically relevant complexes, 5′-adenylyl-β,γ-imidodiphosphate (AMPPNP)·Mg2+, AMPPNP·Mg2+·pantothenate, ADP·Mg2+·phosphopantothenate, and AMP phosphoramidate (AMPPN)·Mg2+, revealed a large conformational change in the dimeric enzyme. The amino-terminal nucleotide binding domain rotates to close the active site, and this allows the P-loop to engage ATP and facilitates required substrate/product interactions at the active site. Biochemical analyses showed that the transition between the inactive and active conformations, as assessed by the binding of either ATP·Mg2+ or acyl-CoA to PANK3, is highly cooperative indicating that both protomers move in concert. PANK3(G19V) cannot bind ATP, and biochemical analyses of an engineered PANK3/PANK3(G19V) heterodimer confirmed that the two active sites are functionally coupled. The communication between the two protomers is mediated by an α-helix that interacts with the ATP-binding site at its amino terminus and with the substrate/inhibitor-binding site of the opposite protomer at its carboxyl terminus. The two α-helices within the dimer together with the bound ligands create a ring that stabilizes the assembly in either the active closed conformation or the inactive open conformation. Thus, both active sites of the dimeric mammalian pantothenate kinases coordinately switch between the on and off states in response to intracellular concentrations of ATP and its key negative regulators, acetyl(acyl)-CoA.
Sentiment analysis of the correlation between regular tweets and retweets

In this paper, we study the influence from the sentiment of regular tweets on retweeting. We propose a method to calculate the sentiment score for each tweet and each Twitter user. This method enables us to place the tweets and retweets into the same time period to explore the sentiment factor. We adopt the correlation coefficient between the sentiment scores of regular tweets and those of retweets to measure the influence. We categorize the Twitter users in three different ways to investigate three factors, which are the number of followers, betweenness centrality and the types of accounts. Community detection and machine learning are integrated into our approach. We find that the difference for correlation coefficients exists between different levels of the number of followers, and different types of users. Our method sheds a light on better predicting the dynamics of tweets diffusion by including the sentiment factor into the prediction model.
PROCESSING OF ASAR/AP MODE DATA FOR SHIP DETECTION

Ship detection is always a vital section of the marine application of spaceborne synthetic aperture radar (SAR), especially after the launch of ENVISAT in 2002. ASAR’s Alternating Polarization (AP) mode can simultaneously provide two well geo-registered images in different polarization pairs, namely VV/HH, HH/HV, and VV/VH. This dual polarization function can probably help to enhance the ship detection efficiency by SAR images. In this paper, we aimed to find a solution to the fusion schemes of AP data. Because of the property and formats differences between AP Single-Look Complex (APS) and Precision (APP), processors of APS and APP for ship detection were investigated individually. Preliminary results of the proposed processing strategy reveal it can not only largely reduce speckle effects and sea clutters, but can also guarantee the ship detection performance.
Controlled prospective study on the mental health of women following pregnancy loss.

OBJECTIVE This study investigated the hypothesis that following a pregnancy loss, women have more mental health complaints than women who give birth to a living baby. METHOD Mental health was assessed for 2,140 women during their first trimester of pregnancy through use of the Dutch version of the SCL-90. A total of 227 women who had lost their babies and 213 women who gave birth to a living baby were followed over a period of 18 months, during which their mental health was reassessed four times. RESULTS When mental health complaints at the beginning of pregnancy and reproductive loss history were taken into account, data analysis revealed that up to 6 months after their pregnancy loss, women showed greater depression, anxiety, and somatization than women who gave birth to living babies. Over time the mental health of women who had experienced a loss was found to improve and at 1 year was comparable to that of women who gave birth to living babies and to that of women in general. CONCLUSIONS The majority of women are able to recover from pregnancy loss without psychiatric treatment in about 1 year. A pregnancy loss is nevertheless a stressful life event that can give rise to a marked deterioration in a woman's mental health, particularly in the first 6 months following loss.
Spectral Analysis Driven Sparse Matching of 3D Shapes

In this work we present an approach for matching three-dimensional mesh objects related by isometric transfor- mations and scaling. We propose to utilize the Scale invariant Scale-DoG detector and Local Depth SIFT mesh descriptor, to derive a statistical voting-based scheme to robustly estimate the scale ratio between the registered meshes. This paves the way to formulating a novel non-rigid mesh registration scheme, by matching sets of sparse salient feature points using spectral graph matching. The resulting approach is shown to compare favorably with previous state-of-the-art approaches in registering meshes related by partial alignment, while being a few orders of magnitude faster.
GROUPWARE TOOLKITS FOR SYNCHRONOUS WORK

Groupware toolkits let developers build applications for synchronous and distributed computer-based conferencing. This chapter describes four components that we believe toolkits must provide. A run-time architecture automatically manages the creation, interconnection, and communications of both centralized and distributed processes that comprise conference sessions. A set of groupware programming abstractions allows developers to control the behaviour of distributed processes, to take action on state changes, and to share relevant data. Groupware widgets let interface features of value to conference participants be added easily to groupware applications. Session managers let people create and manage their meetings and are built by developers to accommodate the group's working style. We illustrate the many ways these components can be designed by drawing on our own experiences with GroupKit, and by reviewing approaches taken by other toolkit developers.
ENERGY EFFICIENCY OPTIMIZATION OF MECHANICAL NUMERICAL CONTROL MACHINING PARAMETERS

In order to improve the energy efficiency of mechanical numerical control (NC) maching parameters, the main factors that affect the selection of process parameters are put forward first. Then, the energy efficiency optimization method of NC machining parameters is analyzed in detail. In addition, optimization test conditions of numerical control machining based on Taguchi method and multi-objective optimization model of NC machining parameters based on energy efficiency and time are discussed in detail. Moreover, the model is solved on the basis of particle swarm optimization. Finally, the energy efficiency optimization results of NC parameters are analyzed from three aspects. The results show that the proposed optimization method has a certain validity and feasibility and can provide a certain theoretical support for improving the energy efficiency of computer numerical control (CNC) machine tools.
Evaluation of Amino Acid and Energy Utilization in Feedstuff for Swine and Poultry Diets

An accurate feed formulation is essential for optimizing feed efficiency and minimizing feed cost for swine and poultry production. Because energy and amino acid (AA) account for the major cost of swine and poultry diets, a precise determination of the availability of energy and AA in feedstuffs is essential for accurate diet formulations. Therefore, the methodology for determining the availability of energy and AA should be carefully selected. The total collection and index methods are 2 major procedures for estimating the availability of energy and AA in feedstuffs for swine and poultry diets. The total collection method is based on the laborious production of quantitative records of feed intake and output, whereas the index method can avoid the laborious work, but greatly relies on accurate chemical analysis of index compound. The direct method, in which the test feedstuff in a diet is the sole source of the component of interest, is widely used to determine the digestibility of nutritional components in feedstuffs. In some cases, however, it may be necessary to formulate a basal diet and a test diet in which a portion of the basal diet is replaced by the feed ingredient to be tested because of poor palatability and low level of the interested component in the test ingredients. For the digestibility of AA, due to the confounding effect on AA composition of protein in feces by microorganisms in the hind gut, ileal digestibility rather than fecal digestibility has been preferred as the reliable method for estimating AA digestibility. Depending on the contribution of ileal endogenous AA losses in the ileal digestibility calculation, ileal digestibility estimates can be expressed as apparent, standardized, and true ileal digestibility, and are usually determined using the ileal cannulation method for pigs and the slaughter method for poultry. Among these digestibility estimates, the standardized ileal AA digestibility that corrects apparent ileal digestibility for basal endogenous AA losses, provides appropriate information for the formulation of swine and poultry diets. The total quantity of energy in feedstuffs can be partitioned into different components including gross energy (GE), digestible energy (DE), metabolizable energy (ME), and net energy based on the consideration of sequential energy losses during digestion and metabolism from GE in feeds. For swine, the total collection method is suggested for determining DE and ME in feedstuffs whereas for poultry the classical ME assay and the precision-fed method are applicable. Further investigation for the utilization of ME may be conducted by measuring either heat production or energy retention using indirect calorimetry or comparative slaughter method, respectively. This review provides information on the methodology used to determine accurate estimates of AA and energy availability for formulating swine and poultry diets.
Gas and stellar dynamics in NGC 1068: probing the galactic gravitational potential

We present SAURON integral field spectrography of the central 1.5 kpc of the nearby Seyfert 2 galaxy NGC 1068, encompassing the well-known near-infrared (NIR) inner bar observed in the K band. We have successively disentangled the respective contributions of the ionized gas and stars, thus deriving their two-dimensional distribution and kinematics. The [O III] and H beta emission lines exhibit a very different spatial distribution and kinematics, the latter following inner spiral arms with clumps associated with star formation. Strong inward streaming motions are observed in both the H beta and [O III] kinematics. The stellar kinematics also exhibit clear signatures of a non-axisymmetric tumbling potential, with a twist in both the velocity and Gauss-Hermite h(3) fields. We re-examined the long-slit data of Shapiro, Gerssen & van der Marel using a pPXF: a strong decoupling of the Gauss-Hermite term h(3) is revealed, and the central decrease of Gauss-Hermite term h(4) hinted in the SAURON data is confirmed. These data also suggest that NGC 1068 is a good candidate for a so-called sigma drop. We confirm the possible presence of two separate pattern speeds applying the Tremaine-Weinberg method to the Fabry-Perot H alpha map. We also examine the stellar kinematics of bars formed in N-body + smoothed particle hydrodynamics (SPH) simulations built from axisymmetric initial conditions approximating the luminosity distribution of NGC 1068. The resulting velocity, dispersion and higher order Gauss-Hermite moments successfully reproduce a number of properties observed in the two-dimensional kinematics of NGC 1068 and the long-slit data, showing that the kinematic signature of the NIR bar is imprinted in the stellar kinematics. The remaining differences between the models and the observed properties are likely mostly due to the exclusion of star formation and the lack of the primary large-scale oval/bar in the simulations. These models nevertheless suggest that the inner bar could drive a significant amount of gas down to a scale of similar to 300 pc. This would be consistent with the interpretation of the sigma drop in NGC 1068 being the result of central gas accretion followed by an episode of star formation.
In vivo observing x-ray attenuation of intratumor injection of indocyanine green

We report our experimental results of in vivo observing x-ray attenuation of intra-tumor injection of indocyanine green (ICG). An eight- to nine-week-old male BALB/c mouse weighting between 15 and 20 g is used in the experiments, which has been implanted with myeloma cell line (SP2/0) two week before. The system used to monitor the intratumor diffusion of ICG is a digital x-ray imaging system. It works at 33kVp, 0.3mAs, 4 seconds and 1.5×magnification. The objective of this research is to study the x-ray attenuation at different area, which represented by gray-scale value. Compare to the ROI in the tissue without ICG and ROI of black background in the image, there is an obvious change before and after injecting ICG in the tumor, which is the area ICG can diffuse to. It shows the feasibility of using digital x-ray imaging system to dynamically, effectively and noninterventionly monitor the diffusion of the ICG.
THE INTERPRETATION OF PTYCHOGRAPHICAL RECONSTRUCTIONS FROM SPHALERITE STRUCTURES

Ptychography is an electron diffraction technique in which Bragg reflections are interfered coherently in order to measure the phases of diffraction orders directly. Two simple reconstruction methods exist, which require different degrees of coherence in the illuminating electron beam. Simulations on InP <110> for two electron accelerating voltages suggest that the asymmetric ‘dumbbells’ can be reconstructed for small thicknesses, but that the reconstruction methods break down at thicknesses around 10 nm. At larger thicknesses one reconstruction method yields images which show the phosphorus atom. The phase object approximation is shown to break down at thicknesses of about 3.3 nm.
Suppression of VFTO and VFTC in GIS using Ferrite Rings

In Gas Insulated Substations (GIS) a large number of restrikes occur across the switching contacts when disconnector switch or circuit breaker is operated. Each strike leads to generation of a Very Fast Transient Overvoltage (VFTO), having rise-times in the range of a few ns and is followed by high frequency oscillations. Such overvoltages can cause malfunctioning of protection and control circuits and also initiates faults and influence on other components. Suppression of VFTO is very important in GIS. In this paper the computer simulations were done on 245 kV GIS for switching configuration and the suppressing of VFTO by ferrite ring is put forward. The same procedure is applied on 420 kV, 550kV and 800kV GIS and results are compared and analysed.
Computer simulations of protein folding by targeted molecular dynamics

We have performed 128 folding and 45 unfolding molecular dynamics runs of chymotrypsin inhibitor 2 (CI2) with an implicit solvation model for a total simulation time of 0.4 microseconds. Folding requires that the three‐dimensional structure of the native state is known. It was simulated at 300 K by supplementing the force field with a harmonic restraint which acts on the root‐mean‐square deviation and allows to decrease the distance to the target conformation. High temperature and/or the harmonic restraint were used to induce unfolding. Of the 62 folding simulations started from random conformations, 31 reached the native structure, while the success rate was 83% for the 66 trajectories which began from conformations unfolded by high‐temperature dynamics. A funnel‐like energy landscape is observed for unfolding at 475 K, while the unfolding runs at 300 K and 375 K as well as most of the folding trajectories have an almost flat energy landscape for conformations with less than about 50% of native contacts formed. The sequence of events, i.e., secondary and tertiary structure formation, is similar in all folding and unfolding simulations, despite the diversity of the pathways. Previous unfolding simulations of CI2 performed with different force fields showed a similar sequence of events. These results suggest that the topology of the native state plays an important role in the folding process. Proteins 2000;39:252–260. © 2000 Wiley‐Liss, Inc.
The Association Rule Mining System for Acquiring Knowledge of DBpedia from Wikipedia Categories

Wikipedia categories are a useful source of knowledge that is usually expressed in a noun-phrase that contains information about concepts of entities or relations among entities. In DBpedia KBs, they categorize their entities into Wikipedia categories using RDF triples. The RDF triples represent only categories of entities, but not concepts of entities or relations among entities despite the fact that expression of Wikipedia categories contain a wealth of those types of information. In this regard, We propose a method that extracts RDF triples encoding concepts of entities or relations among entities from RDF triples encoding Wikipedia categories of each DBpedia entities using association rule mining techniques that mainly utilize lexical patterns in category expression and a hierarchy of categories. Our extensive experiments show that our approach can mine association rules with more high quality than those of state-of-the-art approaches in this problem.
