WEBVIZ: A Tool for World Wide Web Access Log Analysis

Various programs have emerged that provide statistical analysis of World-Wide Web (WWW) access logs. These programs typically detail the number of accesses for a file, the number of times a site has visited the database, and some programs even provide temporal analysis of requests1. However, these programs are not interactive nor do they provide visualizations of the local database. WebViz was developed with the intention of providing WWW database maintainers and designers with a graphical view of their local database and access patterns. That is, by incorporating the Web-Path paradigm into interactive software, users can see not only the documents (represented visually as nodes) in their database but also the hyperlinks travelled (represented visually as links) by users requesting documents from the database. WebViz further enables uses to selectively filter the access log (i.e. restrict the graphical view by specifying the desired domain names or DSN numbers, directory names, and start and stop times), control bindings to graph attributes (i.e. node size, border width and color as well as link width and color can be bound to frequency and recency information), play back the events in the access log (i.e. re-issue the logged sequence of requests), select a layout of nodes and links that best presents the database’s structure, and examine the graph at any instant in time. Clearly, WebViz is a useful WWW database utility given that it can provide the user with graphical information about document accesses and the paths taken by users through the database. Such analyses can facilitate structural and contextual changes resulting in a more efficient use of the document space. This paper details the implementation of WebViz and outlines possible future extensions.
Why Summaries of Research on Psychological Theories are Often Uninterpretable

Null hypothesis testing of correlational predictions from weak substantive theories in soft psychology is subject to the influence of ten obfuscating factors whose effects are usually (1) sizeable, (2) opposed, (3) variable, and (4) unknown. The net epistemic effect of these ten obfuscating influences is that the usual research literature review is well-nigh uninterpretable. Major changes in graduate education, conduct of research, and editorial policy are proposed.
The application of smooth particle hydrodynamics to the modelling of solid materials

This thesis explores the mesh-free computer modelling technique of Smooth Particle Hydrodynamics (SPH), and explores its usage in solid mechanics applications. A review of the context in which SPH can be used, the theory behind the governing equations and the adaptations carried out to enable elastic body problems to be simulated is presented. An algorithm is proposed to improve the ability for SPH to model contact between deformable surfaces. Non-linear behaviour is simulated via the introduction of plasticity, a statistical damage model and the introduction of friction between surfaces. It is shown how SPH can successfully model the buckling in slender rods and match predictions even under extreme deformations. The culmination of these techniques is used to simulate the mechanical properties of thermal barrier coatings (TBC). The simulated effect of increasing the size of gaps in the columnar structure of TBC is shown to reduce hardness. Higher coefficients of inter-column friction are suggested to be able to enhance the load bearing properties of the TBC system. The future research and improvements to the SPH technique are explored along with a discussion about the appropriate methodology of adapting SPH to meet a range of modelling requirements.
A novel algorithm on adaptive image compressed sensing with sparsity fitting

When the image is compressed adaptively with compressed sensing theory, the determination of sampling rate and sparsity threshold are highly subjective. In order to solve the problem, an accurately adaptive sampling algorithm with sparsity fitting is proposed in this paper. This algorithm determines the minimum sampling rate under certain sparsity to meet the PSNR requirements by iteration, and an optimal objective function of sampling rate choices is obtained by fitting sparsity and sampling rate data with the method of least squares. The adaptive sampling algorithm is simulated based on TVAL3. Experimental results show that the PSNR values of reconstructed images are higher than that with the same fixed sampling rate algorithm, and the PSNR increment of clear texture distinction images can reach at least 3.5dB. Compared to the roughly adaptive compression method, when the average sampling rate is lower, the reconstructed image obtains a higher PSNR value.
Developing Multi-Agent Systems with Dynamic Binding Mechanism

Agents in many complex applications are often dynamic, which means that their abilities, services and even design objectives can change at run-time. Though a great number of agent-oriented modeling languages and methodologies have been proposed, it is still a challenge to develop complex multi-agent systems with dynamic agents. In this paper, the technology requirements to analyze, design and implement dynamic agents are discussed. A dynamic binding mechanism to develop multi-agent systems is proposed based on caste that is the basic abstraction to specify agents' behaviors and elementary modular unit to design and implement multi-agent systems. In our approach, the dynamic behaviors of agents are realized as the change of castes that agents bind to by executing "join" and "quit" operations on agent's casteships at run-time. The mechanism also enables agents to change the status of its castes to be either active or inactive at run-time by executing operations "activate" and "deactivate". In order to specify and analyze the adaptive agents, a graphical notation of caste transition diagram is designed and an example is illustrated. The posed problems and future research about dynamic binding mechanism are also discussed at last.
Stable Principal Component Pursuit

In this paper, we study the problem of recovering a low-rank matrix (the principal components) from a high-dimensional data matrix despite both small entry-wise noise and gross sparse errors. Recently, it has been shown that a convex program, named Principal Component Pursuit (PCP), can recover the low-rank matrix when the data matrix is corrupted by gross sparse errors. We further prove that the solution to a related convex program (a relaxed PCP) gives an estimate of the low-rank matrix that is simultaneously stable to small entry-wise noise and robust to gross sparse errors. More precisely, our result shows that the proposed convex program recovers the low-rank matrix even though a positive fraction of its entries are arbitrarily corrupted, with an error bound proportional to the noise level. We present simulation results to support our result and demonstrate that the new convex program accurately recovers the principal components (the low-rank matrix) under quite broad conditions. To our knowledge, this is the first result that shows the classical Principal Component Analysis (PCA), optimal for small i.i. d. noise, can be made robust to gross sparse errors; or the first that shows the newly proposed PCP can be made stable to small entry-wise perturbations.
The RGG box motif of the herpes simplex virus ICP27 protein mediates an RNA-binding activity and determines in vivo methylation

ICP27 is an essential herpes simplex virus type 1 nuclear regulatory protein that is required for efficient viral gene expression. Although the mechanism by which ICP27 regulates genes is unknown, a variety of evidence suggests that it functions posttranscriptionally, and recent studies indicate that it is an RNA-binding protein. Previously, we noted that a short arginine- and glycine-rich sequence in ICP27 (residues 138 to 152) is similar to an RGG box motif, a putative RNA-binding determinant found in a number of cellular proteins (W. Mears, V. Lam, and S. Rice, J. Virol. 69:935-947, 1995). In the present study, we have further investigated ICP27's association with RNA and examined the role of the RGG box in RNA binding. We find that ICP27 binds efficiently to RNA homopolymers composed of poly(G) and weakly to poly(U) RNA homopolymers. Poly(G) binding activity maps to the N-terminal 189 residues of ICP27 and requires the RGG box sequence. Using a northwestern blotting assay, we demonstrate that the RGG box alone (residues 140 to 152) can mediate RNA binding when attached to a heterologous protein. As many cellular RGG box proteins are methylated on arginine residues, we also investigated the in vivo methylation status of ICP27. Our results demonstrate that ICP27 is methylated in herpes simplex virus-infected cells. Methylation is dependent on the presence of the RGG box, suggesting that one or more arginine residues in the RGG box sequence are modified. These data demonstrate that ICP27 displays the characteristics of an RGG box-type RNA-binding protein.
PaRSEC: Exploiting Heterogeneity to Enhance Scalability

New high-performance computing system designs with steeply escalating processor and core counts, burgeoning heterogeneity and accelerators, and increasingly unpredictable memory access times call for one or more dramatically new programming paradigms. These new approaches must react and adapt quickly to unexpected contentions and delays, and they must provide the execution environment with sufficient intelligence and flexibility to rearrange the execution to improve resource utilization. The authors present an approach based on task parallelism that reveals the application's parallelism by expressing its algorithm as a task flow. This strategy allows the algorithm to be decoupled from the data distribution and the underlying hardware, since the algorithm is entirely expressed as flows of data. This kind of layering provides a clear separation of concerns among architecture, algorithm, and data distribution. Developers benefit from this separation because they can focus solely on the algorithmic level without the constraints involved with programming for current and future hardware trends.
Whole-Body Imaging Modalities in Oncology

This article outlines the expanding approaches to whole-body imaging in oncology focusing on whole-body MRI and comparing it to emerging applications of whole-body CT, scintigraphy, and above all PET CT imaging. Whole-body MRI is widely available, non-ionizing and rapidly acquired, and inexpensive relative to PET CT. While it has many advantages, WBMRI is non-specific and, when compared to PET CT, is less sensitive. This article expands each of these issues comparing individual modalities as they refer to specific cancers.
A Comparative Study of 2 Manual-based Self-Help Interventions, Acceptance and Commitment Therapy and Applied Relaxation, for Persons With Chronic Pain

ObjectiveThe aim of this study was to compare 2 self-help-based interventions; a coping-oriented approach, applied relaxation (AR) and an acceptance-oriented approach, acceptance and commitment therapy (ACT), for persons with chronic pain. MethodThis study is a randomized control trial (N=90) with a mixed between-within participants design with repeated measures. Interventions in both conditions comprised an initial face-to-face session, a 7-week manual-based self-help intervention including weekly therapist telephone support and a concluding face-to-face session. Outcome measures included satisfaction with life, depression, anxiety, acceptance of chronic pain, level of function, and pain intensity. Effects were measured at preintervention and postintervention and at 6 and 12 months after the end of intervention. ResultsThe results show that the ACT condition increased their level of acceptance significantly compared with the AR condition. There was also a marginally significant interaction effect regarding satisfaction with life in which the ACT condition had improved in comparison to the AR condition. Further, the ACT condition reported a higher level of function and decreased pain intensity compared with the AR condition. Both conditions improved significantly regarding depression and anxiety. ConclusionsA manual-based self-help intervention with weekly therapist support in an ACT format adds value to the treatment repertoire for persons suffering with chronic pain.
THE ROLE OF DIETARY ENZYMES IN IMPROVING AMINO ACID DIGESTIBILITY

The optimum amino acid balance for broilers varies with ambient temperature. In particular, the optimum dietary arginine:lysine ratio increases at heat-stress temperatures, probably reflecting a reduced uptake of arginine from the digestive tract. Feed enzymes have generally improved amino acid digestibility but a standardised digestibility procedure is required before digestible amino acids will become the basis of dietary formulation.
Using Color for Object Recognition

Object Recognition is an important task in many Computer Vision problems. The problem is usually defined as classifying new images given a set of training images. One of the most challenging problems is Category-level Object Recognition which has got attention in the past decade. In this project the work on Fine-grained Category Object Recognition is presented. Despite General Object Recognition, images in this problem have a lot in common. But they still have differences that we can use for the classification. In this research, we use color feature for classification in many different ways. We are going to try to use color features which has not given much attention by the computer vision community to see if we can use it to improve the classification of 200 bird species (CUB200)[7]. The goal is to improve the performance of existing papers [5] [4] and also find more general way to use color in other similar problems.
Identification and Characterization of Novel Genes Expressed Preferentially in the Corpora Allata or Corpora Cardiaca During the Juvenile Hormone Synthetic Period in the Silkworm, Bombyx mori

Juvenile hormone (JH) plays important roles in insect development and physiology. JH titer is tightly regulated to coordinately adjust systemic physiology and development. Although control of JH titer is explained by the expression of JH biosynthetic enzymes in the corpora allata (CA), molecular mechanisms that regulate the expression of these genes remain elusive. In the present study, to identify novel regulators of JH biosynthetic genes, we conducted a gene expression screen using the CA and corpora cardiaca (CC) of the silkworm, Bombyx mori, in the JH synthesis period. We identified seven candidate genes and characterized their properties through extensive expression analyses. Of these candidates, we found that a novel gene, which encodes type II phosphatidylinositol 3,4-bisphosphate [PI(3,4)P2] 4-phosphatase, shows highly correlated expression with JH titer. In addition, expression of this gene was strongly upregulated by starvation, when JH biosynthetic enzyme genes are concurrently upregulated. These results, for the first time, imply possible involvement of phosphoinositol signal in regulation of JH biosynthesis, providing novel insights into molecular mechanisms of nutrition-dependent regulation of JH biosynthesis.
Anodic Bonding of Silicon-Pyrex and Silicon-Soda Lime Glass at Room Temperature

Silicon wafer bonding opens possibilities in creating MEMS devices and anodic bonding is found to be the most relevant wafer bonding technique process in constructing and packaging MEMS. This paper reports on the bond strength comparison between silicon and different glass based materials via anodic bonding. Two types of glass based surface used pyrex and soda lime glass. Bonding temperature is set at room temperature while a high direct current voltage of 15kV. Experiments were carried out using an in-house designed anodic bonder and the bond strength were measured using a bond strength tester. The anodic approach process was done in two sets which are before and after the cleaning process for each sample. Results show that all samples showed higher bond strength after the cleaning process. Silicon-soda lime glass have higher bonding strength of 1950 Pa compared to silicon-pyrex bonding which only gives 1850 Pa of bond strength.
Recycling of the Asialoglycoprotein Receptor in Isolated Rat Hepatocytes

We have examined the rate of dissociation of internalized 1a61-asialo-orosomucoid-receptor complexes in freshly isolated rat hepatocytes. Cell suspensions were washed with ethylene glycol bis(@-aminoethyl ether)N,N,N',N'-tetraacetic acid at 0 "C to remove surfacebound ligand and then assessed for the retention of radioactive glycoprotein in the presence of digitonin, which permeabilized the cells and released the internal soluble contents. In cells which initially contained only surface-bound ligand, about 50% of the internalized ligand dissociated from receptor very rapidly (t% d 2.5 min, k a 0.28 rnin"), at 37 "C, whereas the other 50% dissociated more slowly with apparent first order kinetics (tlh = 50 min, k = 0.014 min-'). This equal distribution of internalized ligand into two compartments, from which dissociation occurred with very different kinetics, did not depend on the extent of surface receptor occupancy and also occurred under non-steady state conditions of continuous exposure to ligand. Ligand entering both the rapid and slow dissociation compartments was eventually degraded with apparent first order kinetics (k = 0.0047 rnin"), suggesting that the intracellular routing of ligand to lysosomes after dissociation from either compartment was via the same pathway. The fast and slow dissociation of receptor-ligand complexes were also distinguished by different temperature sensitivities; the slow dissociation process ceased below 18 "C, whereas the fast dissociation process still proceeded. The equal partition of internalized complexes into the two kinetic compartments did not change as a function of temperature but did change as cells continued to endocytose asialo-orosomucoid at 37 "C. As the internal receptor pool approached a steady state level of occupancy, there was an increase in the average time for receptor recycling and an increase in the fraction of incoming receptor-ligand complexes which dissociated rapidly (-75%). In addition, under steady state conditions, the rate of the slow dissociation process increased (k = 0.026 min-l, tH = 27 min).
Possibilities and limitations of A2MX4 and AMX3 crystal growth

Materials with non-linear properties such as thermal hysteresis of birefringence, electrooptic, thermooptic, piezooptic and thermochromic phenomena are very interesting both from scientific and practical points of view. They can be applied to photonic technology as optical memories, optical modulators, temperature and stress sensors. The examples of such materials are A2MX4 and AMX3 crystals (where A organic cation, M transition metal, X halogens). Possibilities and limitation of the A2MX4 and AMX3 crystals growth from water and organic solution have been discussed in order to determine the optimal parameters of the growth.
Single image super resolution based on content-aware constraint and intensity-order constraint

This paper presents a novel single image super resolution (SR) based on a content-aware consstraint and an intensity-order constraint. The proposed method, generates an SR image by minimizing an energy that consists of a data term, the content-aware constraint and the intensity-order constraint. The content-aware constraint can preserve texture patterns while reducing noise in a smooth region, while the intensity-order constraint can reduce ringing artifacts by penalizing the inconsistency of the intensity-magnitude relation. Experimental results show that the proposed method outperforms existing reconstruction-based SR methods in terms of PSNR and SSIM.
Small cell neuroendocrine (Oat cell) carcinoma of the breast

A 52‐year‐old woman with small cell neuroendocrine (oat cell) carcinoma of the breast is described. Identical neoplasms have been reported in a variety of extrapulmonary sites, but this is the first description of a primary mammary tumor of this type. The patient had axillary and hepatic metastases at the time of diagnosis, and the clinical course suggests that this tumor behaves in an aggressive fashion, analogous to other small cell neuroendocrine carcinomas. The relationship of small cell neuroendocrine carcinoma of the breast to mammary “carcinoid tumor” or argyrophilic carcinoma is discussed. Cancer 52:121‐125, 1983.

BATCH-FABRICATED MEMS MAGNETIC VIBRATIONAL ENERGY HARVESTERS

This paper reports the fabrication and characterization of fully-integrated, fully-batch-microfabricated electromagnetic vibrational energy harvesters. The 4 – 15 mm structures utilize embedded NdFeB powder micromagnet technology, and represent some of the smallest magnetic energy harvesters demonstrated to date. Of three different designs, the best performing demonstrated 13.2 μVrms at the device resonance of 530 Hz and 1 g (9.8 m/s) excitation. This corresponds to a predicted maximum output power of 23 pW and a normalized power density of 1.6 ×10 W/cm·g. While the power from these prototype devices is limited, ongoing design and fabrication improvements aim to increase their performance.
Survey of Command Execution Systems for NASA Spacecraft and Robots

NASA spacecraft and robots operate at long distances from Earth Command sequences generated manually, or by automated planners on Earth, must eventually be executed autonomously onboard the spacecraft or robot. Software systems that execute commands onboard are known variously as execution systems, virtual machines, or sequence engines. Every robotic system requires some sort of execution system, but the level of autonomy and type of control they are designed for varies greatly. This paper presents a survey of execution systems with a focus on systems relevant to NASA missions.
