Implementation of owner distinction function for therapeutic pet robots
Authors: Nambo Hidetaka , Kimura Haruhiko , Hirose Sadaki 
Published: June 2009

AbstractRapid progress in robotics has led to the widespread use of robots in many fields. A typical case is pet robots, based on animal pets such as dogs or cats. Animal pets are also known to have a therapeutic effect, and efforts to apply pet robots in animal‐assisted therapy have begun. We have investigated a method of owner recognition for pet robots, emphasizing their therapeutic effects. This paper proposes a real‐time owner recognition method intended for implementation in pet robots. Specifically, it provides a real‐time matching algorithm and a forgetting mechanism. In real‐time matching, matching and data acquisition are performed simultaneously. The forgetting mechanism deletes owner features in the pet robot's database. It has the advantages of reducing matching costs or database size and allowing adjustment to a change of owner. The effectiveness and practicality of the method are evaluated experimentally. © 2009 Wiley Periodicals, Inc.

A control method for inverter used for distributed power supply under voltage sag condition
Authors: Hatano Nobuhiko , Taniguchi Yuji , Kouchi Katsuhiko 
Published: June 2009

AbstractInverters which are used for distributed power supply, such as solar cell or fuel cell system, tend to stop easily as a result of voltage sag. In the present electric power system, there is little problem due to this characteristic of inverter. But if the number of those inverters connected to the power system increases, the quality of system voltage and frequency may deteriorate by stop of the inverters. In addition, regarding the fuel cell system, its output power cannot be controlled quickly, and the whole system may stop by a rise of inside temperature. Copyright © 2004 Wiley Periodicals, Inc.For these problems, we tried to realize high continuous operation ability of inverters used for distributed power supply under voltage sag condition. This paper shows a control method of inverter for the over‐current caused by sudden change or unbalance of the system voltage and examination results with three‐phase 200 V–4 kW class inverter system. © 2009 Wiley Periodicals, Inc.

The politics of high‐level nuclear waste management in Sweden: confined research versus research in the wild
Authors: Anshelm Jonas , Galis Vasilis 
Published: June 2009

AbstractIn 2010, the Swedish nuclear energy industry is expected to announce a proposal for the final storage of high‐level nuclear waste in bedrock. The underground storage concept is attracting increasing interest from other countries in Europe. Because of the nature of Swedish political culture, the development of the actual method for final disposal is commonly perceived as resting on consensus and democratic cooperation. However, this paper argues that the aforementioned disposal method instead represents the outcome of intense conflict between the nuclear energy industry and the anti‐nuclear movement. Accordingly, any investigation of the technical and political solutions to controversial environmental problems should involve the study of lay people and social movements. The present study does so, employing theoretical notions from science and technology studies that allow the analysis to conceptualize actions and strategies (enactments) of the nuclear energy industry (confined research) and the anti‐nuclear movement (research in the wild).

Published: June 2009

AbstractColonization with helminthic parasites induces mucosal regulatory cytokines, like IL‐10 or TGF‐β, that are important in suppressing colitis. Helminths induce mucosal T cell IL‐10 secretion and regulate lamina propria mononuclear cell (LPMC) Th1 cytokine generation in an IL‐10‐dependent manner in WT mice. Helminths also stimulate mucosal TGF‐β release. As TGF‐β exerts major regulatory effects on T lymphocytes, we investigated the role of T lymphocyte TGF‐β signaling in helminthic modulation of intestinal immunity. T cell TGF‐β signaling is interrupted in TGF‐β receptor II dominant negative (TGF‐βRII DN) mice by T‐cell‐specific over‐expression of a TGF‐βRII DN. We studied LPMC responses in WT and TGF‐βRII DN mice that were uninfected or colonized with the nematode, Heligmosomoides polygyrus. Our results indicate an essential role of T cell TGF‐β signaling in limiting mucosal Th1 and Th2 responses. Furthermore, we demonstrate that helminthic induction of intestinal T cell IL‐10 secretion requires intact T cell TGF‐β‐signaling pathway. Helminths fail to curtail robust, dysregulated intestinal Th1 cytokine production and chronic colitis in TGF‐βRII DN mice. Thus, T cell TGF‐β signaling is essential for helminthic stimulation of mucosal IL‐10 production, helminthic modulation of intestinal IFN‐γ generation and H. polygyrus‐mediated suppression of chronic colitis.

Published: June 2009

AbstractA new zymography method for simultaneous detection of two different enzymatic activities (lipolytic and proteolytic) using a single SDS‐containing or native‐conformation gel and a mixed‐substrate (glycerol tributyrate and fibrin) (MS)1 gel was developed. After routine electrophoresis, SDS in the gel was removed by treatment with Triton X‐100. Gel proteins were electrotransferred to the MS gel. To visualize lipolytic activity, the MS gel was incubated at 37°C (for 6 or 24 h) until clear bands against an opaque background were observed. To detect proteolytic activity, the same MS gel was stained with Coomassie brilliant blue. Using this method, we show that six lipolytic enzymes from Staphylococcus pasteuri NJ‐1 and four proteolytic enzymes from two Bacillus strains, B. licheniformis DJ‐2 and B. licheniformis NJ‐5, isolated from soil, can be simultaneously detected.
An alternate approach for modelling of transient vaporous cavitation
Authors: Sumam K. S. , Thampi S. G. , Sajikumar N. 
Published: June 2009

AbstractSimulation of cavitating flow has been a thrust area of research for long period due to its practical and economic importance. The major hurdle in developing a numerical model for such flows is the difficulty in representing the quick phase changes, in general, and the alternate change of flow from single phase to two phase and back, in particular. In this case, instability due to sharp variation of flow characteristics also restricts the development of numerical models. The present study demonstrates the use of a relatively simple formulation for the analysis of flow characteristics in a quasi‐rigid pipeline under abrupt phase changes due to cavitation. A popular scheme—MacCormack scheme—was used for developing a numerical solution for this problem. It uses the conservative form of the governing equations, viz. conservation of mass and momentum, the transport equation and the constitutive relationship. The model can handle variable properties of the water–vapour mixture, which is highly compressible. A newly introduced pressure under‐relaxation method overcomes the numerical instability due to sharp variation of flow characteristics during phase change. The model could predict the instant of occurrence of vapour pressure, duration of persistence of vapour pressure and the rise of pressure due to vapour collapse to satisfactory levels with published data and experimental results.

A conformal decomposition finite element method for modeling stationary fluid interface problems
Authors: Noble David R. , Newren Elijah P. , Lechman Jeremy B. 
Published: June 2009

AbstractA method is developed for modeling fluid transport in domains that do not conform to the finite element mesh. One or more level set functions are used to describe the fluid domain. A background, non‐conformal mesh is decomposed into elements that conform to the level set interfaces. Enrichment takes place by adding nodes that lie on the interfaces. Unlike other enriched finite element methods, the proposed technique requires no changes to the underlying element assembly, element interpolation, or element quadrature. The complexity is entirely contained within the element decomposition routines. It is argued that the accuracy of the method is no less than that for eXtended Finite Element Methods (XFEM) with Heaviside enrichment. The accuracy is demonstrated using multiple numerical tests. In all cases, optimal rates of convergence are obtained for both volume and surface quantities. Jacobi
preconditioning is shown to remove the ill‐conditioning that may result from the nearly degenerate conformal elements. Copyright © 2009 John Wiley & Sons, Ltd.
Ultrasonographic hepatic steatosis increases prediction of mortality risk from elevated serum gamma-glutamyl transpeptidase levels # †

Published: June 2009

Abstract
The aim of the present study was to investigate the association of serum gamma-glutamyltransferase (GGT) levels with all-cause mortality and to assess the impact of ultrasonographic findings of hepatic hyperechogenicity in that association. We used data from 4,160 subjects (2,044 men and 2,116 women) recruited for the population-based Study of Health in Pomerania (SHIP) without baseline hepatitis B and C infections or liver cirrhosis. GGT was divided into age- and sex-dependent quintiles to calculate overall and sex-specific crude incidence mortality rates. Hepatic steatosis was defined by elevated GGT levels (>80%) and the presence of hyperechogenic liver ultrasound. We used multiple-adjusted Cox proportional hazards regression models, first, to assess the direct effect of GGT on all-cause mortality, second, to stratify according to the ultrasonographic finding, and third, to investigate potential mediating effects of cardiometabolic risk factors. During 29,810 person-years (7.3 years, median) of follow-up, 307 individuals (7.5%) died, resulting in a death rate of 0.86 deaths per 1000 person-years. Elevated GGT levels were associated with increased risk of mortality in men (hazard ratio [HR] 1.49; 95% confidence interval [CI], 1.08–2.05), but not in women (HR 1.30; 95% CI, 0.80–2.12). This association was even stronger in men with hepatic steatosis (HR 1.98; 95% CI, 1.21–3.27). Cause-specific mortality analysis by cardiovascular disease deaths confirmed the sex-specific association. Adjustment for cardiometabolic risk factors did not affect the estimates. Conclusion: In the case of increased GGT levels, liver ultrasound should be performed, not only for diagnosis, but also for further risk stratification. (Hepatology 2009.)

Published: June 2009

AbstractApc‐deficient Min mice feature low expression of lipoprotein lipase (LPL), high concentration of serum triglyceride (TG), fatty change of the liver and large numbers of intestinal polyps. We have reported that induction of LPL expression reduces serum lipid, especially TG, improves fatty change of the liver and inhibits intestinal polyp formation in the mice. In this study, fatty change/lipid accumulation in intestinal mucosa and polyps in Min mice were analyzed by Oil‐red O staining and electron microscopy. A number of large lipid droplets were found in the epithelia of the upper part of polyps. On the other hand, small lipid droplets were only slightly observed at the tip of the villi in non‐tumoros parts of the small intestine of Min mice and in the villi of wild‐type mice. Moreover, low‐density lipoprotein receptor (LDLR) was overexpressed in the area where lipid droplets were observed. The expression levels of LDLR mRNA in the intestinal polyps of Min mice were ∼3 times higher compared to those in the non‐tumoros parts. Remarkable expression of cyclooxygenase‐2 was mainly distributed in stromal cells and some in epithelial cells. It is speculated that lipid accumulation in the intestinal polyps may play an important role in intestinal polyp formation in Apc‐deficient mice. © 2009 UICC

AbstractStarting from an experimental model that accounts for the 2 most important adverse processes to successful therapy of Ewing's sarcoma (EWS), chemoresistance and the presence of metastasis at the time of diagnosis, we defined a molecular signature of potential prognostic value. Functional annotation of differentially regulated genes revealed 3 major networks related to cell cycle, cell‐to‐cell interactions and cellular development. The prognostic impact of 8 genes, representative of these 3 networks, was validated in 56 EWS patients. High mRNA expression levels of HINT1, IFITM2, LGALS3BP, STOML2 and c‐MYC were associated with reduced risk to death and lower risk to develop metastasis. At multivariate analysis, LGALS3BP, a matricellular protein with a role in tumor progression and metastasis, was the most important predictor of event‐free survival and overall survival. The association between LGALS3BP and prognosis was confirmed at protein level, when expression of the molecule was determined in tumor tissues but not in serum, indicating a role for the protein at local tumor microenvironment. Engineered enhancement of LGALS3BP expression in EWS cells resulted in inhibition of anchorage independent cell growth and reduction of cell migration and metastasis. Silencing of LGALS3BP expression reverted cell behavior with respect to in vitro parameters, thus providing further functional validation of genetic data obtained in clinical samples. Thus, we propose LGALS3BP as a novel reliable indicator of prognosis, and we offer genetic signatures to the scientific communities for cross‐validation and meta‐analysis, which are indispensable tools for a rare tumor such as EWS.
Macroporous photocrosslinked elastomer scaffolds containing microposity: Preparation and in vitro degradation properties
Authors: Ilagan Bernadette G. , Amsden Brian G. 
Published: June 2009

AbstractThe engineering of soft tissue would benefit from the development of effective biodegradable scaffolds capable of dynamic, elastic loading. For this purpose, highly porous, elastomeric scaffolds containing microporous struts were prepared using a dual porogen approach and a photocrosslinkable elastomer. The combination of paraffin microbeads distributed through a water‐in‐[star‐poly(lactide‐co‐ϵ‐caprolactone) triacrylate dissolved in ethyl acetate] emulsion followed by photocrosslinking generated a macroporous foam scaffold of average porosities between 90% to 93%, with an average pore diameter of 104 ± 31 μm with struts containing micropores of 3.1 ± 2 μm average diameter. The mechanical properties of the scaffolds were readily manipulatable by altering the molecular weight of the star‐poly(lactide‐co‐ϵ‐caprolactone) triacrylate prepolymer used. The elastomer scaffolds degraded at the same rate as nonporous polymer samples of the same molecular weight, and exhibited similar changes in mass loss, mechanical properties, and sol fraction during in vitro degradation as found with the nonporous scaffolds. The modulus and stress at break of the scaffolds decreased continuously during degradation while the strain at break remained constant. These scaffolds show potential for use in the engineering of soft tissues. © 2009 Wiley Periodicals, Inc. J Biomed Mater Res, 2010
Pancreato‐enteric anastomosis: The duct evagination technique

Published: June 2009

AbstractPancreatic anastomotic failure remains the most frequent and potentially life‐threatening complication following Pancreatoduodenectomy. Numerous modifications in the technique of the pancreatoenteric anastomosis have been reported. We suggest a simple modification which involves “evaginating” the cut end of the pancreatic duct. This technique helps avoid a compromise of the pancreatic ductal patency, and by achieving a wide pancreatic ductal opening can facilitate a safer pancreato‐enteric anastomosis. In addition, by possibly decreasing the likelihood of post‐operative pancreatic ductal stenosis, it has the potential to reduce post‐Pancreatoduodenectomy pancreatic exocrine insufficiency. The modification acts as an adjunct to an already established technique yielding good results. J. Surg. Oncol. 2009;100:277–278. © 2009 Wiley‐Liss, Inc.

Measurement results show that when the supply voltage Vdd is biased at 1.2 V, the free‐running oscillation frequency of the ILFD is tunable from 1.19 GHz to 1.0 GHz, and at the incident power of 0 dBm, the operation locking range is about 0.65 GHz, from the incident frequency 3.03–3.68 GHz. The core power consumption is 2.05 mW at Vdd = 1.2 V. © 2009 Wiley Periodicals, Inc.

A simple low‐loss broadband 1–14 GHz microstrip‐to‐slotline transition
Authors: Wang Nai‐Biao , Jiao Yong‐Chang , Zhang Li , Song Yue , Zhang Fu‐Shun 
Published: June 2009

AbstractThe improved version of a broadband microstrip‐to‐slotline transition is presented. The transition consists of a microstrip radial stub, a slot radial stub, and a multisection matching transformer. An extremely large angle slot radial stub is introduced into the design to reduce radiation loss and maximize the field converting around the microstrip‐slotline tee junction. From experimental results, the improved transition has greater bandwidth and lower loss than the earlier designs. With the return loss of better than 15 dB, the 1‐ and 3‐dB back‐to‐back insertion loss bandwidth can cover from 1.04 to 5.13 GHz (1 : 4.9) and from 1.02 to 13.90 GHz (1:13.6), respectively. The proposed planar transition has the advantages of compact size, wide bandwidth, simple structure, and straightforward design procedure. © 2009 Wiley Periodicals, Inc.

Published: June 2009

AbstractA compact shorted rectangular‐ring slot antenna fed by a coplanar waveguide is presented for circular polarization operations. This proposed antenna has only 40 mm square size in the applications of WLAN 2.4 GHz band. It seems the most compact size while referenced to other shorted ring slot antennas in recent articles. The reduced size is over 30% will save much cost and antenna can apply to portable devices. Simulated and measured data are matched in the reflection coefficient, axial ratio (AR), radiation patterns, and gain. Its measured center frequency and impedance bandwidth are 2.38 GHz and 15.1%, respectively. Also, the frequency of minimum axial‐ratio and axial‐ratio bandwidth are 2.43 GHz and 4.1%, respectively. From the bandwidths of view, both impedance and AR bandwidths can cover the 2.4 GHz band's applications. The radiation patterns are broadside radiations. Forward radiation belongs to right hand circular polarization and backward one is left hand circular polarization, respectively. Also, antenna gain is about 3 dBic in the operating band of WLAN 2.4 GHz band. The antenna performances and compact size of the proposed antenna are easy to be applied in the consumer products. © 2009 Wiley Periodicals, Inc.
