Visual Interhemispheric and Striate-Extrastriate Cortical Connections in the Rabbit: A Multiple Tracer Study

Previous studies in rabbits identified an array of extrastriate cortical areas anatomically connected with V1 but did not describe their internal topography. To address this issue, we injected multiple anatomical tracers into different regions in V1 of the same animal and analyzed the topography of resulting extrastriate labeled fields with reference to the patterns of callosal connections and myeloarchitecture revealed in tangential sections of the flattened cortex. Our results extend previous studies and provide further evidence that rabbit extrastriate areas resemble the visual areas in rats and mice not only in their general location with respect to V1 but also in their internal topography. Moreover, extrastriate areas in the rabbit maintain a constant relationship with myeloarchitectonic borders and features of the callosal pattern. These findings highlight the rabbit as an alternative model to rats and mice for advancing our understanding of cortical visual processing in mammals, especially for projects benefiting from a larger brain.
Logical Foundations of RDF(S) with Datatypes

The Resource Description Framework (RDF) is a Semantic Web standard that provides a data language, simply called RDF, as well as a lightweight ontology language, called RDF Schema. We investigate embeddings of RDF in logic and show how standard logic programming and description logic technology can be used for reasoning with RDF. We subsequently consider extensions of RDF with datatype support, considering D entailment, defined in the RDF semantics specification, and D* entailment, a semantic weakening of D entailment, introduced by ter Horst. We use the embeddings and properties of the logics to establish novel upper bounds for the complexity of deciding entailment. We subsequently establish two novel lower bounds, establishing that RDFS entailment is PTime-complete and that simple-D entailment is coNP-hard, when considering arbitrary datatypes, both in the size of the entailing graph. The results indicate that RDFS may not be as lightweight as one may expect.
Managing Pipeline-Recon gurable FPGAs

While recon gurable computing promises to deliver incomparable performance, it is still a marginal technology due to the high cost of developing and upgrading applications. Hardware virtualization can be used to signi cantly reduce both these costs. In this paper we describe the bene ts of hardware virtualization, and show how it can be acheived using a combination of pipeline recon guration and run-time scheduling of both con guration streams and data streams. The result is PipeRench, an architecture that supports robust compilation and provides forward compatibility. Our preliminary performance analysis predicts that PipeRench will outperform commercial FPGAs and DSPs in both overall performance and in performance per mm.
Transcription and summarization of voicemail speech

This paper describes the development of a system to transcribe and summarize voicemail messages. The results of the research we present are two-fold. First, a hybrid connectionist approach to the Voicemail transcription task shows that competitive performance can be achieved using a context-independent system with fewer parameters than those based on mixtures of Gaussian likelihoods. Second, an effective and robust combination of statisti- cal with prior knowledge sources for term weighting is used to extract information from the decoder’s output in order to deliver summaries to the message recipients via a GSM Short Message Service (SMS) gateway.
Visual and Auditory Inputs into the Cuneate Nucleus

Sound clicks or light flashes modify somatic sensory activity in the cuneate nucleus of the cat. The techniques of gross potential recording in the cuneate nucleus or medial lemniscal tract, of single unit recording in the cuneate nucleus, and of excitability testing of cuneate terminals demonstrate this heterosensory interactionsensory interaction.
On the power of (even a little) centralization in distributed processing

We propose and analyze a multi-server model that captures a performance trade-off between centralized and distributed processing. In our model, a fraction p of an available resource is deployed in a centralized manner (e.g., to serve a most loaded station) while the remaining fraction 1-p is allocated to local servers that can only serve requests addressed specifically to their respective stations. Using a fluid model approach, we demonstrate a surprising phase transition in steady-state delay, as p changes: in the limit of a large number of stations, and when any amount of centralization is available (p>0), the average queue length in steady state scales as log 1/1-p 1/1-λ when the traffic intensity λ goes to 1. This is exponentially smaller than the usual M/M/1-queue delay scaling of 1/1-λ, obtained when all resources are fully allocated to local stations (p=0). This indicates a strong qualitative impact of even a small degree of centralization. We prove convergence to a fluid limit, and characterize both the transient and steady-state behavior of the finite system, in the limit as the number of stations N goes to infinity. We show that the queue-length process converges to a unique fluid trajectory (over any finite time interval, as N → ∞), and that this fluid trajectory converges to a unique invariant state vI, for which a simple closed-form expression is obtained. We also show that the steady-state distribution of the N-server system concentrates on vI as N goes to infinity.
The contemporary construction of nurse empowerment.

PURPOSE (a) To describe how nursing's construction of the concept of empowerment has selectively shaped the manner in which this concept has been applied to nursing professional practice and (b) to explicate clearly the breadth of the concept by highlighting the complex interactions that shape nurse empowerment. DESIGN AND METHODS This integrative literature review analyzes academic literature published between 1960 and 2010 in the fields of nursing, management, and women's studies utilizing an evolutionary concept analysis method to explore the concept of nurse empowerment. FINDINGS While the literature suggests that empowerment is an emergent product of interactions among individual, organizational, and sociocultural factors, nursing has adopted a construction of empowerment that focuses primarily on organizational antecedents. This construction has enabled nursing to operationalize the concept in order to address a number of pressing challenges. Yet, this construction only limitedly addresses the individual and sociocultural factors that impact nurses' empowerment. CONCLUSIONS In order to promote professional practice through the mobilization of power, scholarship must further investigate the complex interactions producing empowerment. CLINICAL RELEVANCE For nurses to practice as professionals, they must be empowered to take action and respond to challenges using professional skill and knowledge. Unless nurses feel empowered to act, they will rely too heavily on rigid bureaucratic structures rather than their own professional power to guide practice.
Intergenerational Assistance to Adult Children

This study considers how the number of sisters and brothers affects the flow of aid from older parents to adult children. Using data from the 2004 Middletown Kinship Survey (N = 338), the authors find that the aid adults receive from their parents varies by the gender composition of the sibship. Adults with more sisters tend to receive less assistance from their older parents. This holds true across a range of helping behaviors, including financial, gifts, transportation, housework and yard work, and technology. The pattern does not hold for brothers. Possible explanations include resource dilution (daughters drawing more on parents’ resources, leaving fewer resources to go around) or cooperative networks created among sisters (thus rendering aid from parents less necessary).
Attention to health cues on product packages

The objectives of the study were (a) to examine which information and design elements on dairy product packages operate as cues in consumer evaluations of product healthfulness, and (b) to measure the degree to which consumers voluntarily attend to these elements during product choice. Visual attention was measured by means of eye-tracking. Task (free viewing, product healthfulness evaluation, and purchase likelihood evaluation) and product (five different yoghurt products) were varied in a mixed within-between subjects design. The free viewing condition served as a baseline against which increases or decreases in attention during product healthfulness evaluation and purchase likelihood evaluation were assessed. The analysis revealed that the only element operating as a health cue during product healthfulness evaluation was the nutrition label. The information cues used during purchase likelihood evaluation were the name of the product category and the nutrition label. Taken together, the results suggest that the only information element that consumers consistently utilize as a health cue is the nutrition label and that only a limited amount of attention is devoted to read nutrition labels during purchase likelihood evaluations. The study also revealed that the probability that a consumer will read the nutrition label during the purchase decision process is associated with gender, body mass index and health motivation.
FOXP3+ Regulatory T Cells Affect the Development and Progression of Hepatocarcinogenesis

Purpose: Tumor-infiltrating lymphocytes represent the host immune response to cancer. CD4+CD25+FOXP3+ regulatory T cells (Tregs) suppress the immune reaction. The aim of the present study was to investigate the clinicopathologic significance and roles of Tregs and CD8+ T cells during hepatocarcinogenesis. Experimental Design: We examined the infiltration of FOXP3+ Tregs and CD8+ T cells in the tumor stroma and nontumorous liver parenchyma using 323 hepatic nodules including precursor lesions, early hepatocellular carcinoma (HCC), and advanced HCC, along with 39 intrahepatic cholangiocarcinomas and 59 metastatic liver adenocarcinomas. We did immunohistochemical comparative studies. Results: The prevalence of Tregs was significantly higher in HCC than in the nontumorous liver (P < 0.001). The patient group with a high prevalence of Tregs infiltrating HCC showed a significantly lower survival rate (P = 0.007). Multivariate analysis revealed that the prevalence of Tregs infiltrating HCC was an independent prognostic factor. The prevalence of Tregs increased in a stepwise manner (P < 0.001) and that of CD8+ T cells decreased during the progression of hepatocarcinogenesis (P < 0.001). Regardless of the presence of hepatitis virus infection or histopathologic evidence of hepatitis, the prevalence of Tregs was significantly increased in nontumorous liver bearing primary hepatic tumors. Conclusions: Tregs play a role in controlling the immune response to HCC during the progression of hepatocarcinogenesis. It has been suggested that primary hepatic cancers develop in liver that is immunosuppressed by a marked infiltration of Tregs. A high prevalence of Tregs infiltrating HCC is thought to be an unfavorable prognostic indicator.
Protein Phosphatase 2A and Its Methylation Modulating Enzymes LCMT-1 and PME-1 Are Dysregulated in Tauopathies of Progressive Supranuclear Palsy and Alzheimer Disease

Hyperphosphorylated tau aggregates are characteristic of tauopathies including progressive supranuclear palsy (PSP) and Alzheimer disease (AD), but factors contributing to pathologic tau phosphorylation are not well understood. Here, we studied the regulation of the major tau phosphatase, the heterotrimeric AB55αC protein phosphatase 2 A (PP2A), in PSP and AD. The assembly and activity of this PP2A isoform are regulated by reversible carboxyl methylation of its catalytic C subunit, while the B subunit confers substrate specificity. We sought to address whether the decreases in PP2A methylation and its methylating enzyme, leucine carboxyl methyltransferase (LCMT-1), which are reported in AD, relate to tau pathology or to concomitant amyloid pathology by comparing them in the relatively pure tauopathy PSP. Immunohistochemical analysis of frontal cortices showed that methyl-PP2A is reduced while demethyl-PP2A is increased, with no changes in total PP2A or B55α subunit, resulting in a reduction in the methyl/demethyl PP2A ratio of 63% in PSP and 75% in AD compared to controls. Similarly, Western blot analyses showed a decrease of methyl-PP2A and an increase of demethyl-PP2A with a concomitant reduction in the methyl/demethyl PP2A ratio in both PSP (74%) and AD (76%) brains. This was associated with a decrease in LCMT-1 and an increase in the demethylating enzyme, protein phosphatase methylesterase (PME-1), in both diseases. These findings suggest that PP2A dysregulation in tauopathies may contribute to the accumulation of hyperphosphorylated tau and to neurodegeneration.
Utterance verification using an optimized k-nearest neighbour classifier

Utterance veriﬁcation can be seen as a conventional pattern classiﬁcation problem in which a feature vector is obtained for each hypothesized word in order to classify it as either correct or incorrect. In this paper, we study the application to this problem of an optimized version of the (cid:0) -Nearest Neighbour decision rule which also incorporates an adequate feature selection technique. Experiments are reported showing that it gives comparatively good results.
Simultaneous single-pulse observations of radio pulsars II. Orthogonal polarization modes in PSR B1133+16

In this letter, we present a study of orthogonal polarization modes in the radio emission of PSR B1133+16, conducted within the frame of simultaneous, multi-frequency, single-pulse observations. Simultaneously observing at two frequencies (1.41 GHz and 4.85 GHz) provides the means to study the bandwidth of polarization features such as the polarization position angle. We find two main results. First, that there is a high degree of correlation between the polarization modes at the two frequencies. Secondly, the modes occur more equally and the fractional linear polarization decreases towards higher frequencies. We discuss this frequency evolution and propose propagation effects in the pulsar magnetosphere as its origin.
“Is This What Motherhood is All About?”

This article focuses on transition to first-time motherhood and explores the experiences of a group of women as they anticipate, give birth, and engage in early mothering. It illuminates how these women draw on, weave together, and challenge dominant strands of discourse that circumscribe their journeys into motherhood. Using qualitative longitudinal data, prenatal and postnatal episodes of transition are explored. The analysis and juxtaposing of these data reveal the different ways women anticipate and gradually make sense of becoming mothers. While there is a disjuncture between expectations and experiences for these new mothers, this article draws attention to the different ways women discursively position themselves through transition. It reveals how birth experiences can act as a discursive turning point and underscores the obduracy of some strands of dominant discourse. These findings contribute to a subtler and more nuanced understanding of the dynamic interplay between personal experience and gendered discourses.
Dietary Fat Content and Fiber Type Modulate Hind Gut Microbial Community and Metabolic Markers in the Pig

Obesity leads to changes in the gut microbial community which contribute to the metabolic dysregulation in obesity. Dietary fat and fiber affect the caloric density of foods. The impact of dietary fat content and fiber type on the microbial community in the hind gut is unknown. Effect of dietary fat level and fiber type on hindgut microbiota and volatile fatty acid (VFA) profiles was investigated. Expression of metabolic marker genes in the gut, adipose tissue and liver was determined. A 2×2 experiment was conducted in pigs fed at two dietary fat levels (5% or 17.5% swine grease) and two fiber types (4% inulin, fermentable fructo-oligosaccharide or 4% solka floc, non-fermentable cellulose). High fat diets (HFD) resulted in a higher (P<0.05) total body weight gain, feed efficiency and back fat accumulation than the low fat diet. Feeding of inulin, but not solka floc, attenuated (P<0.05) the HFD-induced higher body weight gain and fat mass accumulation. Inulin feeding tended to lead to higher total VFA production in the cecum and resulted in a higher (P<0.05) expression of acyl coA oxidase (ACO), a marker of peroxisomal β-oxidation. Inulin feeding also resulted in lower expression of sterol regulatory element binding protein 1c (SREBP-1c), a marker of lipid anabolism. Bacteria community structure characterized by DGGE analysis of PCR amplified 16S rRNA gene fragments showed that inulin feeding resulted in greater bacterial population richness than solka floc feeding. Cluster analysis of pairwise Dice similarity comparisons of the DGGE profiles showed grouping by fiber type but not the level of dietary fat. Canonical correspondence analysis (CCA) of PCR- DGGE profiles showed that inulin feeding negatively correlated with back fat thickness. This study suggests a strong interplay between dietary fat level and fiber type in determining susceptibility to obesity.
Lively Questions for Demographers about Death at Older Ages

This is an expanded version of comments on the future of the demography of aging at an invited session of the 2008 annual meeting of the Population Association of America. In an introduction, John Haaga offers reasons for a revival of interest in population aging, including greater realization of plasticity in aging trajectories at both individual and societal levels. Linda Martin proposes that population scientists working in aging emulate those studying fertility and family planning in previous decades, learning from interventions (in this case, aimed at increasing retirement savings and reducing disability at older ages). Changes in family structure will increasingly affect new cohorts of the elderly, and Linda Waite speculates on the ways in which changes in the economy, medicine, and the legal environment could affect the social context for aging. Research on mortality at older ages is "alive and well" asserts James Vaupel, who sets out six large questions on mortality trends and differentials over time and across species. Lastly, Wolfgang Lutz expands the scope of projections, showing the considerable uncertainty about the timing and pace of population aging in the developing world and the effects on future elderly of the increases in educational attainment in much of the world during the second half of the twentieth century.

Preoperative prognostic factors for pN2 non-small cell lung cancer.

PURPOSE The prognosis of non-small cell lung cancer (NSCLC) with pathologic mediastinal lymph node involvement (pN2) is poor in general. The majority of previously reported prognostic factors of pN2 disease are not available preoperatively. When we perform preoperative induction chemotherapy, we should undertake therapeutic planning according to preoperative factors. METHODS We focused on preoperative clinicopathologic factors, and investigated the prognosis in 78 patients with pN2 NSCLC who received complete resection. RESULTS Age, gender, histologic subtype, tumor location, smoking status and cT status were not related to patients' survival. On the other hand patients with cN0 disease and normal serum carcinoembryonic antigen (CEA) level had a significant favorable survival (p = 0.038 and p = 0.019, respectively). In addition, comorbidity had a significant survival impact (p = 0.031). Despite there being no independent prognostic factors by multivariate analysis, the patients without all of cN1-2 disease, elevated serum CEA level and comorbidity had a significant favorable prognosis (p = 0.008). CONCLUSION Among the preoperative factors examined, pN2 patients with all cN0 disease, normal serum CEA level and no comorbidities might have a favorable prognosis. Combined use of these might be a useful prognostic determinant, and even in the presence of pN2 disease, patients without these unfavorable 3 factors might have a favorable prognosis when treated with surgery alone.
The disease-resistance gene Pto and the fenthion-sensitivity gene Fen encode closely related functional protein kinases

Resistance to bacterial speck in tomato is governed by a gene-for-gene interaction in which a single resistance locus (Pto) in the plant responds to the expression of a specific avirulence gene (avrPto) in the pathogen. Disease susceptibility results if either Pto or avrPto are lacking from the corresponding organisms. Leaves of tomato cultivars that contain the Pto locus also exhibit a hypersensitive-like response upon exposure to an organophosphorous insecticide, fenthion. Recently, the Pto gene was isolated by a map-based cloning approach and was shown to be a member of a clustered multigene family with similarity to various protein-serine/threonine kinases. Another member of this family, termed Fen, was found to confer sensitivity to fenthion. The Pto protein shares 80% identity (87% similarity) with Fen. Here, Pto and Fen are shown to be functional protein kinases that probably participate in the same signal transduction pathway. '
Augmented Mixture Models for Lexical Disambiguation

This paper investigates several augmented mixture models that are competitive alternatives to standard Bayesian models and prove to be very suitable to word sense disambiguation and related classification tasks. We present a new classification correction technique that successfully addresses the problem of under-estimation of infrequent classes in the training data. We show that the mixture models are boosting-friendly and that both Adaboost and our original correction technique can improve the results of the raw model significantly, achieving state-of-the-art performance on several standard test sets in four languages. With substantially different output to Naive Bayes and other statistical methods, the investigated models are also shown to be effective participants in classifier combination.
Interpreters, arbiters or outsiders: The role of the Min kao Han in Xinjiang society 1

Abstract This paper attempts to identify the variables that define the political and social boundaries within Xinjiang's multi-ethnic society. Traditionally, ethnicity has been the point from which scholars examine political and social loyalties in Xinjiang. It is proposed here that, while ethnicity is a crucial component in defining the divisions in Xinjiang society, it is also important to consider the role of language. This latter trait cuts across ethnic lines and is responsible for creating important subgroups within established communities. The paper will demonstrate that while the Uighur Min kao Han are ethnically Uighur, they culturally and linguistically have taken on many ethnic Chinese characteristics. They are favoured for admission into Chinese society and receive political and employment advantages over their co-ethnics who remain linguistically/culturally Uighur. However, these advantages do not always materialize and the social costs are high. The Min kao Han are generally excluded from the Uighur community, while simultaneously enduring discrimination from the Han. It is argued here that the history of the Min kao Han, as well as the trends in Chinese politics and society affecting this group's future development, are key to understanding what their current role is and will be in the future. It is clear that the psychological condition of the Min kao Han is largely the result of their isolated position in Xinjiang society, and of their experience as children in Han classrooms. It will be shown that there is potential for this group to lead the Uighur population into conflict with the Han, but also, and more importantly, for them to help facilitate reconciliation.
