Comparison of Fast Roll‐to‐Roll Flexographic, Inkjet, Flatbed, and Rotary Screen Printing of Metal Back Electrodes for Polymer Solar Cells

The majority of polymer solar cells reported today employs technology that provide similar performance to ITO-based processing under high vacuum for one or more of the layers in the solar cell stack. Most notably the highly conducting metal back electrode is almost exclusively applied by evaporation of the pure metal. While it is not impossible to envisage mass production of polymer solar cells using vacuum processing it does present some drawbacks in terms of both processing speed, capital investment in processing equipment technical yield and direct process energy. From this point of view it is clear that vacuum processed electrodes should be avoided and electrodes should be printable using methods that provide a high degree of accuracy and high technical yield. When considering large area polymer solar cells (i.e., not laboratory devices) a few reports have employed printable back electrodes mostly by use of silver formulations but also carbon and copper has been discussed whereas copper is unlikely to yield the necessary cost reduction and resistance to oxidation. Most reports have employed flatbed or rotary screen printing whereas other methods are available and described later on. The important question to answer is which technique is most suited for manufacture of polymer solar cell modules in terms of technical yield, materials use and processing speed? Evidently the back electrode has to be of high conductivity, which implies the use of a thick electrode. Therefore thick film printing techniques such as the screen printing techniques have proven excellent while they do present disadvantages in speed due to significant drying requirements but also they do require significant amounts of material. In this paper we employ four different roll-to-roll (R2R) printing methods for printing silver back electrodes for polymer solar cell modules based on the IOne process which is a fully printable, indium-tin-oxide (ITO), and vacuum free
Chronic Supplementation of Curcumin Enhances the Efficacy of Antidepressants in Major Depressive Disorder: A Randomized, Double-Blind, Placebo-Controlled Pilot Study

Abstract Major depressive disorder is a devastating mental illness leading to a lifetime prevalence of higher than 16% on individuals. The treatment delay and inevitable adverse effects are major limitations of current depression interventions. Emerging evidence indicates that curcumin produced significant antidepressant properties in depression in both rodents and humans without adverse effects. Therefore, it is necessary to further clarify the antidepressant actions of curcumin and the underlying mechanism in depressed patients. A total of 108 male adults aged between 31 and 59 years were systematically recruited in Tianjin Anding Hospital. Subjects were administered the Chinese version of 17-item Hamilton Depression Rating Scale and Montgomery-Asberg Depression Rating Scale that measures different scores of depressive symptoms. The subjects were asked to take 2 capsules containing either 1000 mg of curcumin or placebo soybean powder daily for 6 weeks on the basis of their current antidepressant medications. The plasma levels of interleukin 1&bgr;, tumor necrosis factor &agr;, brain-derived neurotrophic factor, and salivary cortisol were measured by enzyme-linked immunosorbent assay before and after curcumin or placebo treatment during the 6-week procedure. Chronic supplementation with curcumin produced significant antidepressant behavioral response in depressed patients by reduction of 17-item Hamilton Depression Rating Scale and Montgomery-Asberg Depression Rating Scale scores. Furthermore, curcumin decreases inflammatory cytokines interleukin 1&bgr; and tumor necrosis factor &agr; level, increases plasma brain-derived neurotrophic factor levels, and decreases salivary cortisol concentrations compared with placebo group. These findings indicate the potential benefits of further implications of supplementary administration of curcumin to reverse the development of depression and enhance the outcome of antidepressants treatment in major depressive disorder.
Replication Initiation from a Novel Origin Identified in the Th2 Cytokine Cluster Locus Requires a Distant Conserved Noncoding Sequence1

Lineage commitment of Th cells is associated with the establishment of specific transcriptional programs of cytokines. However, how Th cell differentiation affects the program of DNA replication has not been addressed. To gain insight into interplays between differentiation-induced transcription regulation and initiation of DNA replication, we took advantage of an in vitro differentiation system of naive T cells, in which one can manipulate their differentiation into Th1 or Th2 cells. We searched for replication origins in the murine IL-4/IL-13 locus and compared their profiles in the two Th cell lineages which were derived in vitro from the same precursor T cells. We identified a replication origin (oriIL-13) downstream from exon 4 of IL-13 and showed that this origin functions in both Th2 and Th1 cells. A distant regulatory element called CNS-1 (conserved noncoding sequence 1) in the IL-4/IL-13 intergenic region coincides with a Th2-specific DNase I-hypersensitive site and is required for efficient, coordinated expression of Th2 cytokines. Replication initiation from oriIL-13 is significantly reduced in Th1 and Th2 cells derived from CNS-1-deficient mice. However, the replication timing of this locus is consistently early during S phase in both Th1 and Th2 cells under either the wild-type or CNS-1 deletion background. Thus, the conserved noncoding element in the intergenic region regulates replication initiation from a distant replication origin in a manner independent from its effect on lineage-specific transcription but not the replication timing of the segment surrounding this origin.
Synthesis of filled pauses based on a disfluent speech model

In the present paper we present a new approach to the synthesis of filled pauses. The problem is tackled from the point of view of disfluent speech synthesis. Based on the synthetic disfluent speech model, we analyse the features that describe filled pauses and propose a model to predict them. The model was implemented and perceptually evaluated with successful results.
The interaction of Lamb waves with defects

The interaction of individual Lamb waves with a variety of defects simulated by notches is investigated using finite-element analysis, and the results are checked experimentally. Excellent agreement is obtained. It is shown that a 2-D Fourier transform method may be used to quantify Lamb wave interactions with defects. The sensitivity of individual Lamb waves to particular notches is dependent on the frequency-thickness product, the mode type and order, and the geometry of the notch. The sensitivity of the Lamb modes a/sub 1/, alpha /sub 0/, and s/sub 0/ to simulated defects in different frequency-thickness regions is predicted as a function of the defect depth to plate thickness ratio and the results indicate that Lamb waves may be used to find notches when the wavelength to notch depth ratio is on the order of 40. Transmission ratios of Lamb waves across defects are highly frequency dependent. <<ETX>>
Symbol Recognition and Artificial Emotion for Making an Autonomoius Robot Attend the AAAI Conference

LABORIUS is a young research laboratory interested in designing autonomous systems that can assist human in real life tasks. To do so, robots require some sort of “social intelligence”, giving them the ability to interact with various types of agents (humans, animals, robots and other physical agents). Our team of robots is made of six Pioneer 2 robots, three indoor and three outdoor models, with each robot equipped with 16 sonars, a compass, a gripper, a camera with a frame grabber and a Fast Track Vision System, a RF Ethernet-modem connection and a Pentium 233 MHz PC-104 onboard computer. The programming environment used is Ayllu (Werger 2000), a tool for development of behavior-based control systems for intelligent mobile robots.
An attempt to synthesize mnnb2s4 and the structural characterization of mnnb3s6

In spite of several attempts at synthesizing MnNb2S4, a II− −III2−VI4 semiconducting material with potentially interesting magnetic properties, MnNb3S6, a closely related compound was always prepared as the majority phase. The material was characterized using X-ray Powder Diffraction data. The refinement of the structure of this material carried out by the Rietveld Method produced results consistent with a previously reported study. The unsuccessful attempts of producing MnNb2S4 raise doubts about the existence of this compound.
Join and Semijoin Algorithms for a Multiprocessor Database Machine

This paper presents and analyzes algorithms for computing joins and semijoins of relations in a multiprocessor database machine. First, a model of the multiprocessor architecture is described, incorporating parameters defining I/O, CPU, and message transmission times that permit calculation of the execution times of these algorithms. Then, three join algorithms are presented and compared. It is shown that, for a given configuration, each algorithm has an application domain defined by the characteristics of the operand and result relations. Since a semijoin operator is useful for decreasing I/O and transmission times in a multiprocessor system, we present and compare two equi-semijoin algorithms and one non-equi-semijoin algorithm. The execution times of these algorithms are generally linearly proportional to the size of the operand and result relations, and inversely proportional to the number of processors. We then compare a method which consists of joining two relations to a method whereby one joins their semijoins. Finally, it is shown that the latter method, using semijoins, is generally better. The various algorithms presented are implemented in the SABRE database system; an evaluation model selects the best algorithm for performing a join according to the results presented here. A first version of the SABRE system is currently operational at INRIA.
Collective rotation of molecules driven by the angular momentum of light in a nematic film.

It is experimentally demonstrated that a circularly polarized laser beam normally incident on a homeotropically aligned nematic film can induce a collective precession of the molecules in the film if the laser intensity is above the threshold for the Freedericksz transition. The effect is shown to result from a transfer of angular momentum from the laser beam to the medium.
SVM-Prot: web-based support vector machine software for functional classification of a protein from its primary sequence

Prediction of protein function is of significance in studying biological processes. One approach for function prediction is to classify a protein into functional family. Support vector machine (SVM) is a useful method for such classification, which may involve proteins with diverse sequence distribution. We have developed a web-based software, SVMProt, for SVM classification of a protein into functional family from its primary sequence. SVMProt classification system is trained from representative proteins of a number of functional families and seed proteins of Pfam curated protein families. It currently covers 54 functional families and additional families will be added in the near future. The computed accuracy for protein family classification is found to be in the range of 69.1-99.6%. SVMProt shows a certain degree of capability for the classification of distantly related proteins and homologous proteins of different function and thus may be used as a protein function prediction tool that complements sequence alignment methods. SVMProt can be accessed at http://jing.cz3. nus.edu. sg/cgi-bin/svmprot.cgi.
Skeletal muscle repair by adult human mesenchymal stem cells from synovial membrane

We have demonstrated previously that adult human synovial membrane-derived mesenchymal stem cells (hSM-MSCs) have myogenic potential in vitro (De Bari, C., F. Dell'Accio, P. Tylzanowski, and F.P. Luyten. 2001. Arthritis Rheum. 44:1928–1942). In the present study, we have characterized their myogenic differentiation in a nude mouse model of skeletal muscle regeneration and provide proof of principle of their potential use for muscle repair in the mdx mouse model of Duchenne muscular dystrophy. When implanted into regenerating nude mouse muscle, hSM-MSCs contributed to myofibers and to long term persisting functional satellite cells. No nuclear fusion hybrids were observed between donor human cells and host mouse muscle cells. Myogenic differentiation proceeded through a molecular cascade resembling embryonic muscle development. Differentiation was sensitive to environmental cues, since hSM-MSCs injected into the bloodstream engrafted in several tissues, but acquired the muscle phenotype only within skeletal muscle. When administered into dystrophic muscles of immunosuppressed mdx mice, hSM-MSCs restored sarcolemmal expression of dystrophin, reduced central nucleation, and rescued the expression of mouse mechano growth factor.
Disparity from Stereo-segment Silhouettes of Weakly-textured Images

We propose a novel robust stereo algorithm for weakly-textured scenes. Unique correspondences existing between the silhouettes of corresponding image segments allow assigning accurate disparities to segment boundary points. This information as well as stereo from the weak texture inside segments, which is extracted using a regionconstrained window-based matching algorithm, are fused and disparities are interpolated inside segments while considering potentially occluded areas derived from the depthordering of segments. The algorithm is applied to a set of weakly-textured images and it is demonstrated that stereo from segment silhouettes often provides sufficient information to reconstruct disparities in weakly- and non-textured image areas. The algorithm is applied to several real stereo images and its performance is evaluated quantitatively using images from the 2006 Middlebury dataset.
Opportunistic predation by small fishes on epibiota of jetty pilings in urban waterways

Epibiota were sampled on nine small jetties in the tidal, urban canals of south-east Queensland, Australia, to determine if the small fishes that are associated with these jetties prey on the epibiota on the pilings of the jetties and whether these fishes depend on the epibiota as a source of food. Epibiota was dominated by barnacles, filamentous and foliose algae and ranged in thickness from 4 to 11 mm. The two species of fishes that associated most closely with jetty pilings, Pandaka lidwilli (Gobiidae) and Monodactylus argenteus (Monodactylidae), were sampled twice during the day and twice during the night for analysis of stomach contents. During the day, the diet of P. lidwilli was dominated by amphipods (c. 70%, by mass of organic content), with copepods, bivalves and bryozoans each contributing <10%. At night, amphipods contributed less (c. 45%) and copepods more (c. 35%). The diet of M. argenteus was dominated by filamentous algae (55%) and amphipods (20%) during the day and filamentous algae (70%) and barnacle cirri (23%) at night. Epibiota, therefore, made a substantial contribution to the diet of the fishes but were not the sole source of food for either species. As jetties were the only structures that supported epibiota in the area, fishes probably sourced their epibiota from the pilings of the jetties. Whether fishes depended on the epibiota was, therefore, tested using a manipulative before-after-control-impact (BACI) study. Three jetties were assigned randomly to each of three treatments: (1) epibiota removed from pilings, (2) epibiota cut and damaged (a procedural control) and (3) epibiota left undisturbed. Abundances of P. lidwilli and M. argenteus around jetty pilings remained similar across all treatments from before to after the removal of epibiota. These results indicate that although fishes consumed epibiota on the jetties, they did not depend on the epibiota of the jetties for food. © 2008 The Fisheries Society of the British Isles.
Screening of human LPHN3 for variants with a potential impact on ADHD susceptibility

Attention deficit hyperactivity disorder (ADHD) is the most common behavioral disorder in childhood, and often has effects detectable into adulthood. Advances in genetic linkage and association analysis have begun to elucidate some of the genetic factors underlying this complex disorder. Recently, we identified LPHN3, a novel ADHD susceptibility gene harbored in 4q, and showed that a LPHN3 common haplotype confers susceptibility to ADHD and predicts effectiveness of stimulant medication. Here we present the mutational analysis of the entire coding region of LPHN3 in a cohort of 139 ADHD subjects and 52 controls from across the USA. We identified 21 variants, of which 14 have been reported and 7 are novel. These include 5 missense, 8 synonymous, and 8 intronic changes. Interestingly, neither susceptibility nor protective haplotype alleles are associated with obviously significant coding region changes, or canonical splice site alterations, suggesting that non‐coding variations determining the quantity and/or quality of LPHN3 isoforms are the likely contributors to this common behavioral disorder. © 2010 Wiley‐Liss, Inc.
Elegantly Colored Paths and Cycles in Edge Colored Random Graphs

We first consider the following problem. We are given a fixed perfect matching $M$ of $[n]$ and we add random edges one at a time until there is a Hamilton cycle containing $M$. We show that w.h. p. the hitting time for this event is the same as that for the first time there are no isolated vertices in the graph induced by the random edges. We then use this result for the following problem. We generate random edges and randomly color them black or white. A path/cycle is said to \emph{zebraic} if the colors alternate along the path. We show that w.h. p. the hitting time for a zebraic Hamilton cycle coincides with every vertex meeting at least one edge of each color. We then consider some related problems and extend to multiple colors. We also briefly consider directed versions.
THE NEW SOFTWARE PACKAGE FOR DYNAMIC HIERARCHICAL CLUSTERING FOR CIRCLES TYPES OF SHAPES

In data mining, efforts have focused on finding methods for efficient and effective cluster analysis in large databases. Active themes of research focus on the scalability of clustering methods, the effectiveness of methods for clustering complex shapes and types of data, high-dimensional clustering techniques, and methods for clustering mixed numerical and categorical data in large databases. One of the most accuracy approach based on dynamic modeling of cluster similarity is called Chameleon. In this paper we present a modified hierarchical clustering algorithm that used the main idea of Chameleon and the effectiveness of suggested approach will be demonstrated by the experimental results.
Electromechanical properties of high- coupling (1-ξ)Pb(Zn1/3Nb2/3)O3-(ξ)PbTiO3 single crystals for sound projectors

Isothermal weak field frequency sweeps were conducted over the temperature range 30 to 140°C on multidomain, oriented, and poled (1-x)Pb(Zn1/3Nb2/3)O3-xPbTiO3 (PZN-PT) single crystals with x = 0.045, 0.06, 0.07, and 0.08 near the ferroelectric rhombohedral (FR)-ferroelectric tetragonal (FT) morphotropic phase boundary (MPB). The temperature dependencies of the small-signal 33-mode electromechanical properties were derived from the isothermal frequency sweeps. Morphotropic compositions with x = 0.06 and 0.07 PT were found to exhibit the largest electromechanical coupling and piezoelectric coefficient, with k33 > 0.90 and d33 ~2300 pC/N, and the lowest short-circuit Young's modulus of ~9 GPa. Reversible zero-field elastic instability attributable to a FR-FO transition was observed under isothermal compression-decompression of a 0.94PZN-0.06PT single crystal. The application of a dc bias field enhanced the FR stability under compression. The large-signal, dc biased, 33-mode electromechanical response was measured under mechanical compressions similar to those used in sound projectors. The remarkable small-signal electromechanical properties are in a good agreement with the large-signal response. The crystal response to thermal, electrical, and mechanical variable is discussed in terms of high-coupling single crystal models.
The magic passport

Once upon a time there was a criminal; he was reading his e-mail when a banner caught his attention: low cost flights for the destination of his dreams! He had already started to book the trip when suddenly realized that, being wanted by the police, he could not use his passport without being arrested. What to do? He could not miss that opportunity, so he called a good friend and they started to think for a possible solution. Do you want to know if they succeeded? Read the rest of the paper and find it out.
Stair recognition with laser range scanning by limb mechanism robot “ASTERISK“

A stair recognition with laser range scanning for continuous stair climbing by limb mechanism “ASTERISK” is proposed. In this research, laser range scanning is divided into rough scan for fast scanning, and precise scan for range scanning. We use 2D laser range finder attached with motor for 3D laser range scanning. As a result of the experiment, the robot could recognize a stair position and posture even it is located at the physical limitation of laser range finder which is 4 m and detect the actual stair up to 6 out of 10 steps which the height is about 5 times of “ASTERISK” normal posture standing height.
C-ME: A 3D Community-Based, Real-Time Collaboration Tool for Scientific Research and Training

The need for effective collaboration tools is growing as multidisciplinary proteome-wide projects and distributed research teams become more common. The resulting data is often quite disparate, stored in separate locations, and not contextually related. Collaborative Molecular Modeling Environment (C-ME) is an interactive community-based collaboration system that allows researchers to organize information, visualize data on a two-dimensional (2-D) or three-dimensional (3-D) basis, and share and manage that information with collaborators in real time. C-ME stores the information in industry-standard databases that are immediately accessible by appropriate permission within the computer network directory service or anonymously across the internet through the C-ME application or through a web browser. The system addresses two important aspects of collaboration: context and information management. C-ME allows a researcher to use a 3-D atomic structure model or a 2-D image as a contextual basis on which to attach and share annotations to specific atoms or molecules or to specific regions of a 2-D image. These annotations provide additional information about the atomic structure or image data that can then be evaluated, amended or added to by other project members.
