p–n‐Junction‐Based Flexible Dye‐Sensitized Solar Cells
Authors: Heng Liping , Wang Xinyi , Yang Nailiang , Zhai Jin , Wan Meixiang , Jiang Lei
Published: December 2009

In this paper, a new type of flexible working electrode, TiO2/CuI/Cu, is reported, in which the p–n junction of TiO2–CuI is introduced into dye‐sensitized solar cells (DSSCs) for the first time. The devices give a high conversion efficiency of up to 4.73% under 1 sun illumination. The excellent performance is ascribed to the existence of the p–n junction, which forms a single directional pathway for electron transport which benefits the charge separation, and improves the efficiency of the flexible solar cells as a result.
From artifacts to aggregations: Modeling scientific life cycles on the semantic Web
Authors: Pepe Alberto , Mayernik Matthew , Borgman Christine L. , Van de Sompel Herbert
Published: December 2009

In the process of scientific research, many information objects are generated, all of which may remain valuable indefinitely. However, artifacts such as instrument data and associated calibration information may have little value in isolation; their meaning is derived from their relationships to each other. Individual artifacts are best represented as components of a life cycle that is specific to a scientific research domain or project. Current cataloging practices do not describe objects at a sufficient level of granularity nor do they offer the globally persistent identifiers necessary to discover and manage scholarly products with World Wide Web standards. The Open Archives Initiative's Object Reuse and Exchange data model (OAI‐ORE) meets these requirements. We demonstrate a conceptual implementation of OAI‐ORE to represent the scientific life cycles of embedded networked sensor applications in seismology and environmental sciences. By establishing relationships between publications, data, and contextual research information, we illustrate how to obtain a richer and more realistic view of scientific practices. That view can facilitate new forms of scientific research and learning. Our analysis is framed by studies of scientific practices in a large, multidisciplinary, multi‐university science and engineering research center, the Center for Embedded Networked Sensing.
Analysis of participation in an online photo‐sharing community: A multidimensional perspective
Authors: Nov Oded , Naaman Mor , Ye Chen
Published: December 2009

In recent years we have witnessed a significant growth of social‐computing communities—online services in which users share information in various forms. As content contributions from participants are critical to the viability of these communities, it is important to understand what drives users to participate and share information with others in such settings. We extend previous literature on user contribution by studying the factors that are associated with various forms of participation in a large online photo‐sharing community. Using survey and system data, we examine four different forms of participation and consider the differences between these forms. We build on theories of motivation to examine the relationship between users' participation and their motivations with respect to their tenure in the community. Amongst our findings, we identify individual motivations (both extrinsic and intrinsic) that underpin user participation, and their effects on different forms of information sharing; we show that tenure in the community does affect participation, but that this effect depends on the type of participation activity. Finally, we demonstrate that tenure in the community has a weak moderating effect on a number of motivations with regard to their effect on participation. Directions for future research, as well as implications for theory and practice, are discussed.

Plasma Polarization in High Gravity Astrophysical Objects
Authors: Iosilevskiy I.
Published: December 2009

Macroscopic plasma polarization, which is created by gravitation and other mass‐acting (inertial) forces in massive astrophysical objects (MAO) is under discussion. Non‐ideality effect due to strong Coulomb interaction of charged particles is introduced into consideration as a new source of such polarization. Simplified situation of totally equilibrium isothermal star without relativistic effects and influence of magnetic field is considered. The study is based on variational approach combined with “local density approximation”. It leads to two local forms of thermodynamic equilibrium conditions: constancy for generalized (electro)chemical potentials and/or conditions of equilibrium for the forces acting on each charged specie. New “non‐ideality potential” and “non‐ideality force” appear naturally in this consideration. Hypothetical sequences of gravitational, inertial and non‐ideality polarization on thermo‐ and hydrodynamics of MAO are under discussion (© 2009 WILEY‐VCH Verlag GmbH & Co. KGaA, Weinheim)
Anomalous and Fickian Diffusion in Two‐Dimensional Dusty Plasmas
Authors: Ott T. , Bonitz M.
Published: December 2009

We provide an overview on diffusion in frictionless two‐dimensional Yukawa liquids as a model for dusty plasmas. Results are obtained for the combined influence of temperature and screening length on the character of diffusion, i.e., on the value of the diffusion exponent at long times (© 2009 WILEY‐VCH Verlag GmbH & Co.

Social function in multiple X and Y chromosome disorders: XXY, XYY, XXYY, XXXY
Authors: Visootsak Jeannie , Graham John M.
Published: December 2009

Klinefelter syndrome (47,XXY) was initially described in the context of its endocrinologic and physical features; however, subsequent studies have revealed specific impairments in verbal skills and social functioning. Males with sex chromosomal aneuploidies are known to have variability in their developmental profile with the majority presenting with expressive language deficits. As a consequence of language delays, they have an increased likelihood of language‐based learning disabilities and social‐emotional problems that may persist through adulthood. Studies on males with 47,XXY have revealed unique behavioral and social profiles with possible vulnerability to autistic traits. The prevalence of males with more than one extra sex chromosome (e.g., 48,XXYY and 48,XXXY) and an additional Y (e.g., 47,XYY) is less common, but it is important to understand their social functioning as it provides insight into treatment implications. © 2009 Wiley‐Liss, Inc.

Gene, brain, and behavior relationships in fragile X syndrome: Evidence from neuroimaging studies
Authors: Lightbody Amy A. , Reiss Allan L.
Published: December 2009

Fragile X syndrome (FraX) remains the most common inherited cause of intellectual disability and provides a valuable model for studying gene‐brain‐behavior relationships. Over the past 15 years, structural and functional magnetic resonance imaging studies have emerged with the goal of better understanding the neural pathways contributing to the cognitive and behavioral outcomes seen in individuals with FraX. Specifically, structural MRI studies have established and begun to refine the specific topography of neuroanatomical variation associated with FraX. In addition, functional neuroimaging studies have begun to elucidate the neural underpinnings of many of the unique characteristics of FraX including difficulties with eye gaze, executive functioning, and behavioral inhibition. This review highlights studies with a focus on the relevant gene‐brain‐behavior connections observed in FraX. The relationship of brain regions and activation patterns to FMRP are discussed as well as the clinical cognitive and behavioral correlates of these neuroimaging findings. © 2009 Wiley‐Liss, Inc.

Cognitive profile of Turner syndrome
Authors: Hong David , Scaletta Kent Jamie , Kesler Shelli
Published: December 2009

Turner syndrome (TS) is a relatively common neurogenetic disorder characterized by complete or partial monosomy‐X in a phenotypic female. TS is associated with a cognitive profile that typically includes intact intellectual function and verbal abilities with relative weaknesses in visual–spatial, executive, and social cognitive domains. In this report, we review previous and current research related to the cognitive profile of TS. We also discuss how cognitive impairments in this syndrome may reflect integrative rather than modular deficits. For example, the less commonly reported areas of verbal difficulty in TS and certain visual–spatial deficits seem significantly influenced by impairments in executive function and spatially loaded stimuli. We provide a summary of cognitive testing measures used in the assessment of visual–spatial and executive skills, which includes test domain descriptions as well as a comprehensive examination of social cognitive function in TS. This review concludes with a discussion of ecological interpretations regarding the meaning of cognitive deficits in TS at the individual level. © 2009 Wiley‐Liss, Inc.

Structural and functional neuroimaging in Klinefelter (47,XXY) syndrome: A review of the literature and preliminary results from a functional magnetic resonance imaging study of language
Authors: Steinman Kyle , Ross Judith , Lai Song , Reiss Allan , Hoeft Fumiko
Published: December 2009

Klinefelter (47,XXY) syndrome (KS), the most common form of sex‐chromosomal aneuploidy, is characterized by physical, endocrinologic, and reproductive abnormalities. Individuals with KS also exhibit a cognitive/behavioral phenotype characterized by language and language‐based learning disabilities and executive and attentional dysfunction in the setting of normal general intelligence. The underlying neurobiologic mechanisms are just now beginning to be elucidated through structural and functional neuroimaging. Here, we review the literature of structural and functional neural findings in KS identified by neuroimaging and present preliminary results from a functional magnetic resonance imaging study examining brain activity during a verb generation task in KS. © 2009 Wiley‐Liss, Inc.

Effects of sex chromosome aneuploidies on brain development: Evidence from neuroimaging studies
Authors: Lenroot Rhoshel K. , Lee Nancy Raitano , Giedd Jay N.
Published: December 2009

Variation in the number of sex chromosomes is a relatively common genetic condition, affecting as many as 1/400 individuals. The sex chromosome aneuploidies (SCAs) are associated with characteristic behavioral and cognitive phenotypes, although the degree to which specific individuals are affected can fall within a wide range. Understanding the effects of different dosages of sex chromosome genes on brain development may help to understand the basis for functional differences in affected individuals. It may also be informative regarding how sex chromosomes contribute to typical sexual differentiation. Studies of 47,XXY males make up the bulk of the current literature of neuroimaging studies in individuals with supernumerary sex chromosomes, with a few small studies or case reports of the other SCAs. Findings in 47,XXY males typically include decreased gray and white matter volumes, with most pronounced effects in the frontal and temporal lobes. Functional studies have shown evidence of decreased lateralization. Although the hypogonadism typically found in 47,XXY males may contribute to the decreased brain volume, the observation that 47,XXX females also show decreased brain volume in the presence of normal pubertal maturation suggests a possible direct dosage effect of X chromosome genes. Additional X chromosomes, such as in 49,XXXXY males, are associated with more markedly decreased brain volume and increased incidence of white matter hyperintensities. The limited data regarding effects of having two Y chromosomes (47,XYY) do not find significant differences in brain volume, although there are some reports of increased head size.

Turner syndrome: Neuroimaging findings: Structural and functional
Authors: Mullaney Ronan , Murphy Declan
Published: December 2009

Neuroimaging studies of Turner syndrome can advance our understanding of the X chromosome in brain development, and the modulatory influence of endocrine factors. There is increasing evidence from neuroimaging studies that TX individuals have significant differences in the anatomy, function, and metabolism of a number of brain regions; including the parietal lobe; cerebellum, amygdala, hippocampus; and basal ganglia; and perhaps differences in “connectivity” between frontal and parieto‐occipital regions. Finally, there is preliminary evidence that genomic imprinting, sex hormones and growth hormone have significant modulatory effects on brain maturation in TS. © 2009 Wiley‐Liss, Inc.
