Proposal for a wireless sensor network visualization system using location estimation technology

In recent years, popularization of wireless sensor networks in various fields including smart houses and environment monitoring systems at factories has been expected. However, it is difficult to grasp the structure and connectivity of dynamically changing networks, because sensor networks are connected by radio waves with each other. For that reason, it will be useful if the location of sensor devices and the structure of wireless sensor networks can be confirmed by visual observation at the time of maintenance or troubleshooting. In this paper, we propose a visualization system for wireless sensor networks using a tablet and location estimation technology. In our proposed system, we make it possible to observe the wireless sensor networks by eyes, by displaying the virtual object representing sensor device link information and sensing data, on the screen of the tablet whose location is estimated. We confirmed that the virtual object is superimposedly displayed in the sensor device on the camera screen, by implementing to iPad a prototype of the algorithm to estimate the locational relationship between the tablet and sensor devices.
Durable remissions in a pivotal phase 2 study of brentuximab vedotin in relapsed or refractory Hodgkin lymphoma.

We present response and survival outcomes of a pivotal phase 2 trial of the antibody-drug conjugate brentuximab vedotin in patients with relapsed/refractory Hodgkin lymphoma following autologous stem cell transplant (N = 102) after a median observation period of approximately 3 years. Median overall survival and progression-free survival were estimated at 40.5 months and 9.3 months, respectively. Improved outcomes were observed in patients who achieved a complete remission (CR) on brentuximab vedotin, with estimated 3-year overall survival and progression-free survival rates of 73% (95% confidence interval [CI]: 57%, 88%) and 58% (95% CI: 41%, 76%), respectively, in this group (medians not reached). Of the 34 patients who obtained CR, 16 (47%) remain progression-free after a median of 53.3 months (range, 29.0 to 56.2 months) of observation; 12 patients remain progression-free without a consolidative allogeneic stem cell transplant. Younger age, good performance status, and lower disease burden at baseline were characteristic of patients who achieved a CR and were favorable prognostic factors for overall survival. These results suggest that a significant proportion of patients who respond to brentuximab vedotin can achieve prolonged disease control. The trial was registered at www.clinicaltrials. gov as #NCT00848926.
Asymptotic Analysis of SPTA-Based Algorithms for No-Wait Flow Shop Scheduling Problem with Release Dates

We address the scheduling problem for a no-wait flow shop to optimize total completion time with release dates. With the tool of asymptotic analysis, we prove that the objective values of two SPTA-based algorithms converge to the optimal value for sufficiently large-sized problems. To further enhance the performance of the SPTA-based algorithms, an improvement scheme based on local search is provided for moderate scale problems. New lower bound is presented for evaluating the asymptotic optimality of the algorithms. Numerical simulations demonstrate the effectiveness of the proposed algorithms.
A Study on Automated Relation Labelling in Ontology Learning

Ontology learning from texts has been proposed as a technology helping ontology designers in the modelling process. Within ontology learning, the discovery of non-taxonomic relations is understood as the problem least addressed. We propose a technique for extraction of lexical items that may give cue in assigning semantic labels to otherwise ‘anonymous’ non-taxonomic relations. The technique has been implemented as extension to the existing Text-to-Onto tool. Experiments have been carried out on a collection of texts describing tour destinations as well as on a semantically annotated general corpus. The paper also discusses evaluation aspects of relation labelling, among which the distinction of prior and posterior precision looks as most important.
Atlas-Guided Quantification of White Matter Signal Abnormalities on Term-Equivalent Age MRI in Very Preterm Infants: Findings Predict Language and Cognitive Development at Two Years of Age

The developmental significance of the frequently encountered white matter signal abnormality (WMSA) findings on MRI around term-equivalent age (TEA) in very preterm infants, remains in question. The use of conventional qualitative analysis methods is subjective, lacks sufficient reliability for producing accurate and reproducible WMSA diagnosis, and possibly contributes to suboptimal neurodevelopmental outcome prediction. The advantages of quantitative over qualitative diagnostic approaches have been widely acknowledged and demonstrated. The purpose of this study is to objectively and accurately quantify WMSA on TEA T2-weighted MRI in very preterm infants and to assess whether such quantifications predict 2-year language and cognitive developmental outcomes. To this end, we constructed a probabilistic brain atlas, exclusively for very preterm infants to embed tissue distributions (i.e. to encode shapes, locations and geometrical proportion of anatomical structures). Guided with this atlas, we then developed a fully automated method for WMSA detection and quantification using T2-weighted images. Computer simulations and experiments using in vivo very preterm data showed very high detection accuracy. WMSA volume, particularly in the centrum semiovale, on TEA MRI was a significant predictor of standardized language and cognitive scores at 2 years of age. Independent validation of our automated WMSA detection algorithm and school age follow-up are important next steps.
Deformation method for 3D identikit creation

An identikit is a model of a head created for a purpose of identification. Nowadays, the police use mostly 2D portrait identification, which is simple but has limited possibilities. Therefore, 3D head models have started to be used as identikits. In this paper, we propose small improvements of Free-Form Shape Deformation (FFSD) for 3D identikits creation, which allow modeling new shapes and keeping important details. With these improvements the FFSD method is able to create various and realistic deformations of a human head model which are necessary to make and identikit is a bit quicker. The improved method has been implemented and used in software prepared for the police.
Stellar populations in the centres of brightest cluster galaxies

This paper is part of a series devoted to the study of the stellar populations in brightest cluster galaxies (BCGs), aimed at setting constraints on the formation and evolution of these objects. We have obtained high signal-to-noise ratio, long-slit spectra of 49 BCGs in the nearby Universe. Here, we derive Single Stellar Population (SSP)-equivalent ages, metallicities and α-abundance ratios in the centres of the galaxies using the Lick/IDS system of absorption line indices. We systematically compare the indices and derived parameters for the BCGs with those of large samples of ordinary elliptical galaxies in the same mass range. We find no significant differences between the index– velocity dispersion relations of the BCG data and those of normal ellipticals, but we do find subtle differences between the derived SSP-parameters. The BCGs show, on average, higher metallicity ([Z/H]) and α-abundance ([E/Fe]) values. We analyse possible correlations between the derived parameters and the internal properties of the galaxies (velocity dispersion, rotation, luminosity) and those of the host clusters (density, mass, distance from BCG to X-ray peak, presence of cooling flows), with the aim of dissentangling if the BCG properties are more influenced by their internal or host cluster properties. The SSP-parameters show very little dependence on the mass or luminosity of the galaxies, or the mass or density of the host clusters. Of this sample, 26 per cent show luminosity-weighted ages younger than 6 Gyr, probably a consequence of recent – if small – episodes of star formation. In agreement with previous studies, the BCGs with intermediate ages tend to be found in cooling-flow clusters with large X-ray excess.
Exemplar-based sparse representation of timbre and prosody for voice conversion

Voice conversion (VC) aims to make one speaker (source) to sound like spoken by another speaker (target) without changing the language content. Most of the state-of-the-art voice conversion systems focus only on timbre conversion. However, the speaker identity is characterized by the source-related cues such as fundamental frequency and energy as well. In this work, we propose an exemplarbased sparse representation of timbre and prosody for voice conversion that does not necessitate separately timbre conversion and prosody conversions. The experiment results show that, in addition to the conversion of spectral features, the proper conversion of prosody features will improve the quality and speaker identity of the converted speech.
Cardiac patterning and morphogenesis in zebrafish

Development of the embryonic vertebrate heart requires the precise coordination of pattern formation and cell movement. Taking advantage of the availability of zebrafish mutations that disrupt cardiogenesis, several groups have identified key regulators of specific aspects of cardiac patterning and morphogenesis. Several genes, including gata5, fgf8, bmp2b, one‐eyed pinhead, and hand2, have been shown to be relevant to the patterning events that regulate myocardial differentiation. Studies of mutants with morphogenetic defects have indicated at least six genes that are essential for cardiac fusion and heart tube assembly, including casanova, bonnie and clyde, gata5, one‐eyed pinhead, hand2, miles apart, and heart and soul. Furthermore, analysis of the jekyll gene has indicated its important role during the morphogenesis of the atrioventricular valve. Altogether, these data provide a substantial foundation for future investigations of cardiac patterning, cardiac morphogenesis, and the relationship between these processes. © 2001 Wiley‐Liss, Inc.

Variant anatomy of the cystic artery in adult Kenyans

Knowledge of the variant vascular anatomy of the subhepatic region is important for hepatobiliary surgeons in limiting operative complications due to unexpected bleeding. The pattern of arterial blood supply of 102 gallbladders was studied by gross dissection. The cystic artery originated from the right hepatic artery in 92.2% of cases. The rest were aberrant and originated from the proper hepatic artery. Accessory arteries were observed to originate from proper hepatic artery (n = 5), left hepatic artery (n = 2), and right hepatic artery (n = 1). Most of the arteries approached the gallbladder in relation to the common hepatic duct (anterior 45.1%, posterior, 46.1%). The other vessels passed anterior to common bile duct (2.9%), posterior to common bile duct (3.9%), or were given off in Calot's triangle. Cystic arteries in this data set show wide variations in terms of relationship to the duct systems. In about one tenth of patients, an accessory cystic artery may need to be ligated or clipped during cholecystectomy. Clin. Anat. 20:943–945, 2007. © 2007 Wiley‐Liss, Inc.
MacrophagesCytomegalovirus in Monocyte-Derived Immediate-Early Promoter of Human Bcl-3-Regulated Transcription from Major

Monocytes/macrophages are key cells in the pathogenesis of human CMV (HCMV) infection, but the in vitro rate of viral production in primary human monocyte-derived macrophages (MDM) is considerably lower than in ﬁbroblasts. Considering that the NF- (cid:1) B signaling pathway is potentially involved in the replication strategy of HCMV through efﬁcient transactivation of the major immediate-early promoter (MIEP), efﬁcient viral replication, and late gene expression, we investigated the composition of the NF- (cid:1) B complex in HCMV-infected MDMs and ﬁbroblasts. Preliminary studies showed that HCMV could grow in primary MDM culture but that the viral titer in culture supernatants was lower than that observed in the supernatants of more permissive MRC5 ﬁbroblasts. EMSA and microwell colorimetric NF- (cid:1) B assay demonstrated that HCMV infection of MDMs increased p52 binding activity without activating the canonical p50/p65 complex. Moreover, Bcl-3 was up-regulated and was demonstrated to associate with p52, indicating p52/Bcl-3 complexes as the major component of the NF- (cid:1) B complex in MDMs. Luciferase assays in promonocytic U937 cells transfected with an MIEP-luciferase reporter construct demonstrated MIEP activation in response to p52 and Bcl-3 overexpression. Chromatin immunoprecipitation assay demonstrated that p52 and Bcl-3 bind the MIEP in acutely HCMV-infected MDMs. In contrast, HCMV infection of MRC5 ﬁbroblasts resulted in activation of p50/p65 heterodimers. Thus, activation of p52/Bcl-3 complexes in MDMs and p50/p65 heterodimers in ﬁbroblasts in response to HCMV infection might explain the low-level
Lysophosphatidylcholine for Efficient Intestinal Lipid Absorption And Lipoprotein Secretion in Caco-2 Cells

Phosphatidylcholine (PC) and its hydrolysates are considered to stimulate intestinal lipid absorption, however, their exact effects on lipoproteins and apolipoprotein (apo) metabolism remain ambiguous. This study aimed to further differentiate the effects of them using fully differentiated enterocyte-like Caco-2 cells. Lipid micelles (oleic acid 0.6, cholesterol 0.05, monooleylglycerol 0.2, taurocholate 2 in mmol/l) with or without choline, PC, and lysoPC (0.2 mmol/l each) were applied apically to Caco-2 cells. 3H-oleic acid and 14C-cholesterol were added to the micelles when necessary. Secreted lipoproteins were analyzed by a HPLC method. LysoPC had the most potent promoting effect on lipid uptake, and lipoprotein and apolipoprotein B-48 secretion among the molecules tested. LysoPC doubled the output of cholesterol and triglyceride as the lipoprotein component, but PC did not. On the other hand, PC only increased the secretion of apoA-IV in the presence of lipid micelles. These findings confirm that the alteration of PC by PLA2 hydrolysis is intrinsically involved in the intestinal lipid absorption process and suggest that PC and its hydrolysis are coordinately associated with not only lipid absorption efficiency but also lipoprotein output and metabolism.
When can embryos learn? A test of the timing of learning in embryonic amphibians

Abstract Learning is crucial to the survival of organisms across their life span, including during embryonic development. We set out to determine when learning becomes possible in amphibian development by exposing spotted salamander (Ambystoma maculatum) embryos to chemical stimuli from a predator (Ambystoma opacum), nonpredator (Lithobates clamitans), or control at developmental stages 16–21 or 36–38 (Harrison 1969). Once exposures were completed and embryos hatched, we recorded the number of movements and time spent moving of individuals in both groups and all treatments. There was no significant difference in number of movements or time spent moving among any of the treatments. The groups that were exposed to predator stimuli and a blank control at stages 36–38 were also tested to determine whether there was a difference in refuge preference or difference in survivorship when exposed to a predator (marbled salamander). There was no difference in survival or refuge preference between individuals; however, all individuals preferred vegetated over open areas regardless of treatment type. We discuss hypotheses for the absence of embryonic learning in this species and suggest it may be the result of the intensity of the predator–prey interaction between the predator, large marbled salamander larvae, and the prey, spotted salamander larvae.
Preliminary Investigation of the Relationship between Weather Data and Hand-Foot-Mouth Disease Cases in Sarawak

This paper investigates the relationship between climate changes and the outbreak of Hand-Foot-Mouth Disease (HFMD) in Sarawak. This work is motivated by the statements made by some researchers that there may be a possibility that the outbreak of the HFMD could have a relationship with the weather. Two quantitative variables which consist of weather data and HFMD cases data are crucial for this research. The weather data comprises of the total amount of rainfall and the mean surface air temperature for the year 2000 until 2008. The evaluation of the variables’ relationship is done by using estimated weather data using spline interpolation during the outbreak of HFMD in Sarawak from year 2000 until 2008. The results obtained indicate that there exists correlation between the climate changes and the outbreak of HFMD cases in Sarawak.
A Study on Influencing Factors for the Output Signal-to-Noise Ratio of FFT Processor and Its Utilization

The influencing factors on the output signal-to-noise ratio (SNR) of FFT processor are studied and a novel method to select the optimal word length for FFT processors is proposed. Taking fixed-point FFT as example, the expressions of showing the influence of input SNR, word-length, and FFT size on the output SNR have been given. Based on the relationship between the SNR of input sequence and the one of output sequence, the minimal word-length selection criterion for FFT processors is derived. The expressions are confirmed by experiment results and the word-length selection criterion is of great importance in designing FFT processors
Recreating Personalization Features of the Youngster Mobile Service Platform with the Dip Toolkit

The Dynamic Information Presentation (DIP) Toolkit provides a range of different personalization techniques that can be assembled in a flexible but straightforward way to create on-line personalized services. This is aimed at producing Webbased presentations. The Youngster Mobile Service Platform (MSP) was developed to combine personalization with context -awareness and provides a range of personalized services to young people who are users of next generation mobile communications devices. An exercise has just been completed in which the personalization features of the Youngster MSP have been recreated using the DIP Toolkit. This exercise provides useful insight into the way in which more conventional Web-based personalization services can be extended to other areas such as mobile communications.
Wage Gradients in an Enlarged EU

In this paper we estimate a sectoral real wage equation for three regional blocs of the enlarged EU that we defined as North (wealthiest EU), South (Greece, Portugal and Spain) and East (acceding Central and Eastern European countries). The estimation results show that real wages react differently in each of the blocs to the impact of market size, location and factor endowments across a range of industrial sectors which differ by their degrees of economies of scale and skill-intensities in the presence of transport costs.
Complete Orthogonal Decomposition for Weighted Least Squares

Consider a full-rank weighted least-squares problem in which the weight matrix is highly ill-conditioned. Because of the ill-conditioning, standard methods for solving least-squares problems, QR factorization and the nullspace method for example, break down. G. W. Stewart established a norm bound for such a system of equations, indicating that it may be possible to find an algorithm that gives an accurate solution. S. A. Vavasis proposed a new definition of stability that is based on this result. He also proposed the NSH algorithm for solving this least-squares problem and showed that it satisfies the new definition of stability. This paper describes a complete orthogonal decomposition algorithm to solve this problem and shows that it is also stable. This new algorithm is simpler and more efficient than the NSH method.
Chronic Rhinosinusitis in Children

Rhinosinusitis is a very common disease worldwide and specifically in the US population. It is a common disease in children but may be underdiagnosed. Several reasons may account to the disease being missed in children. The symptoms in children are limited and can be very similar to the common cold or allergic symptoms. Cough and nasal discharge may be the only symptoms present in children. A high index of suspicion is necessary to make the diagnosis of rhinosinusitis in these children. The majority of those children are treated medically. Only a few number will require surgical intervention when medical treatment fails. Complications of rhinosinusitis, even though rare, can carry a high morbidity and mortality rate.
Clinical, Cosmetic and Investigational Dentistry Dovepress Open Access to Scientific and Medical Research Open Access Full Text Article Dovepress Current Practicality of Nanotechnology in Dentistry. Part 1: Focus on Nanocomposite Restoratives and Biomimetics

First described in 1959 by physicist Richard P Feynman, who saw it as an unavoidable development in the progress of science, nanotechnology has been part of mainstream scientific theory with potential medical and dental applications since the early 1990s. Nanoparticles, nanospheres, nanorods, nanotubes, nanofibers, dendrimers and other nanostructures have been studied for various applications to biologic tissues and systems. While many layers of nano-technologic capability have been envisioned for oral health in the last decade (eg, oral hygiene maintenance, local anesthesia, even whole-tooth replacement), few of these applications have been developed. Part 1 of a three-part series reviews the current clinical utility of nanotech-nology's most tangible contribution to dentistry to date: the restoration of tooth structure with nanocomposites. Characterized by filler-particle sizes of 100 nm, these materials can offer esthetic and strength advantages over conventional microfilled and hybrid resin-based composite (RBC) systems, primarily in terms of smoothness, polishability and precision of shade characterization , plus flexural strength and microhardness similar to those of the better-performing posterior RBCs. Available comparative data for nanocomposites and organically-modified ceramic (Ormocer ®) restoratives are also reviewed. Finally, plausible " next-phase " trends in current nanorestorative research are judiciously examined, including 1) calcium-, phosphate-, and fluoride-ion-releasing nanocomposites for anticaries applications and 2) restorative systems based on biomimetic emulation of the nanomolecular assembly processes inherent in dental enamel formation using nanorods, nanospheres, and recombinant amelogenins.
