Developmental Cognitive Neuroscience Delayed Development of Proactive Response Preparation in Adolescents: Erp and Emg Evidence

The transition from late adolescence to young adulthood is often overlooked in the cognitive neuroscience literature. However this is an important developmental period as even older adolescents have not yet reached adult level ability on many cognitive tasks. Adolescents (16–17-year olds) and young adults (23–30-year olds) were tested on a cued task switching paradigm specifically designed to isolate response preparation from response execution. A combined ERP and eletromyographic (EMG) investigation revealed that adolescents have attenuated contingent negative variation (CNV) activity during response preparation followed by larger P3b amplitude and EMG activity in the incorrect response hand during response execution. This is consistent with deficient response preparation and a reactive control strategy. Conversely young adults engaged increased response preparation followed by attenuated P3b activity and early EMG activity in the correct response hand during response execution which indicates a proactive control strategy. Through real time tracking of response-related processing we provide direct evidence of a developmental dissociation between reactive and proactive control. We assert that adoption of a proactive control strategy by adolescents is an important step in the transition to adulthood.
A generalization of the magnitude squared coherence spectrum for more than two signals: definition, properties and estimation

The coherence spectrum is a well-known measure of the linear statistical relationship between two time series. In this paper, we extend this concept to several processes and define the generalized magnitude squared coherence (GMSC) spectrum as a function of the largest eigenvalue of a matrix containing all the pairwise complex coherence spectra. The GMSC is bounded between zero and one, and attains its maximum when all the processes are perfectly correlated at a given frequency. Furthermore, three different GMSC spectrum estimators, extending those previously proposed for the MSC of two processes, are presented. Specifically, we compare the Welch method, the minimum variance distortionless response (MVDR) estimator and a new estimator based on canonical correlation analysis (CCA).
HPF Directives and Runtime Support for theParallelization of Molecular Dynamics Problems

Codes simulating large particle systems present a high degree of spatial data locality and a signiicant amount of independent computations. However, neither state-of-the-art automatic parallelizers nor HPF compilers with standard data distribution directives are able to exploit eeciently such properties. Nowadays, most of the production applications in this area have been manually parallelized. The process of manual parallelization usually involves drastic rewriting of the original sequential code. This work presents a parallelization strategy that offers: high eeciency similar to that of manual paral-lelization; original program structure is preserved in resulting parallel code; global data structures are decomposed in smaller local structures with the same organization ; initial data decomposition and further communications are handled by calls to an existing runtime support. The simplicity of the resulting code makes the technique very suitable for semi-automatic paralleliza-tion. At last, we analyze an intermediate approach in this direction: the introduction of HPF extensions to provide the compiler with information enough to guess the role of each data structure in particle codes.
Short time series microarray data analysis and biological annotation

Significant gene list is the result of microarray data analysis should be explained for the purpose of biological functions. The aim of this study is to extract the biologically related gene clusters over the short time series microarray gene data by applying unsupervised methods and automatically perform biological annotation of those clusters. In the first step of the study, short time series microarray expression data is clustered according to similar expression profiles. After that, several biological data sources are integrated to get information related with the genes in one of those clusters and new sub-clusters are created by using this unified information. As a last step, biological annotation of gene sub-clusters is performed by using information related with those sub-clusters.
Dysphoria and the prediction and experience of emotion

Depression and dysphoria have been characterised by dampened positive emotional experiences. However, it remains unclear whether dysphoria is also characterised by dampened expectancies about positive emotional experiences. In the present study, participants with (dysphoric group; n=36) and without (non-dysphoric group; n=36) dysphoria reported on their expected and actual emotional responses to winning and losing money in a computer task. Results showed the dysphoric group predicted and experienced less happiness and contentment after winning money than the non-dysphoric group. Results also showed the dysphoric group predicted and experienced as much negative emotion after losing money as the non-dysphoric group. Moreover, the dysphoric group predicted they would experience more happiness after winning money than they actually did, whereas the non-dysphoric group experienced as much happiness as they had predicted. Results suggest that disturbances in positive emotional responding are characteristic of people experiencing dysphoria.
Positive feedbacks of fire, climate, and vegetation and the conversion of tropical savanna

We combine general circulation modeling (GCM), remote sensing, and field results to identify a positive feedback loop in which clearing of tropical savannas results in warmer and drier climate, accelerated fire frequencies, and further tree cover loss. The GCM simulations indicate that ongoing clearing of tropical savannas increases temperatures and wind speeds and decreases precipitation and relative humidity, substantially increasing fire frequency. Using NOAA‐12 satellite images and meteorological data, we estimate that complete savanna clearing will increase fire frequency by 42%. Combining these data with long‐term fire studies, we demonstrate that this fire‐mediated feedback may already be contributing to declining tree densities in the world's savannas and will become increasingly important as vegetation change continues in the coming century.
Employing Laplacian-Gaussian densities for speech enhancement

A new efficient speech enhancement algorithm (SEA) is developed. Noisy speech is first decorrelated and then the clean speech components are estimated from the decorrelated noisy speech samples. The distributions of clean speech and noise are assumed to be Laplacian and Gaussian, respectively. The clean speech components are estimated either by maximum likelihood (ML) or minimum-mean-square-error (MMSE) estimators. These estimators require some statistical parameters that are adaptively extracted by the ML approach during the active speech or silence intervals, respectively. A voice activity detector (VAD) is employed to detect whether the speech is active or not. The simulation results show that this SEA performs as well as a recent high efficiency SEA that employs the Wiener filter. The complexity of this algorithm is very low compared with existing SEAs.
Magic and Bimagic Labeling for Disconnected Graphs

An edge magic total labeling of a graph ( , ) G V E with p vertices and q edges is a bijection f from the set of vertices and edges to 1,2,. , p q  such that for every edge uv in E, ( ) ( ) ( ) f u f uv f v   is a constant k. If t here exist two constants 1 k and 2 k such that the above sum is either 1 k or 2 k , it is said to be an edge bimagic total labeling. A total edge magic (edge bimagic) graph is called a super edge magic (super edge bimagic) if ( ( )) {1,2,. , } f V G p  . A total edge magic (edge bimagic) graph is called a superior edge magic (superior edge bimagic) if ( ( )) {1,2,. , q} f E G  . In this paper we give magic and bimagic labelings for some class of disconnected graphs AMS Subject Classification: 05C78 Keywordgraph, labeling, magic labeling, bimagic labeling, function.
Semi-supervised clustering with soft labels

This paper devises a semi-supervised learning algorithm to cluster text documents. The proposed algorithm clusters multi-dimensional documents using the k-means algorithm. It initially reduces the dimensionality of the text so that the clustering algorithm can perform well in the low dimensional feature space. It also removes the irrelevant, redundant and noisy features from the corpus which may otherwise mislead the underlying algorithm. The proposed method employs pLSA algorithm to generate soft labels from these reduced feature subset and these labels along with the class labels guide the k-means algorithm. Experiments were conducted on Reuters-21,578 dataset and the results obtained showed that the proposed method outperforms many previous clustering algorithms without supervision.
Per-request Contracts for Web Services Transactions

To allow providers to keep their autonomy and ensure the overall system can run satisfactorily, it is common practice in the Web Services environment for providers to reduce the strength of some of the traditionallyrequired ACID properties when offering transactional support. However, current standards require providers to offer a constant level of transactional support for each operation they provide. We describe a method that allows service providers to dynamically decide on the level of transactional support to offer for each client request. This allows the provider to base the level of transactional support offered on the current state of the system and internal logic, resulting in potential benefits for both service providers and consumers.
A selective caching scheme based on request history in content-centric networks

Content-Centric Networks (CCNs) promise to deliver content in a better way than today's Internet. In CCNs, efficient content delivery services can be achieved by using cache storage on routers. However, an effective caching scheme in CCNs is never established, because the communication method in CCNs differs from that in traditional networks. Therefore, we propose a selective caching scheme which only caches content likely to be used next. Furthermore, we show its effectiveness through simulations.
On Profiling Mobility and Predicting Locations of Campus-Wide Wireless Network Users

In this paper, we analyze a year long wireless network users’ mobility trace data collected on ETH Zurich campus. Unlike earlier work in [9], [21], [35], we profile the movement pattern of wireless users and predict their locations. More specifically, we show that each network user regularly visits a list of places, such as a building (also referred to as “hubs”) with some probability. The daily list of hubs, along with their corresponding visit probabilities, are referred to as a mobility profile. We also show that over a period of time (e.g., a week), a user may repeatedly follow a mixture of mobility profiles with certain probabilities associated with each of the profiles. Our analysis of the mobility trace data not only validate the existence of our so-called sociological orbits [13], but also demonstrate the advantages of exploiting it in performing hub-level location predictions. Moreover, such profile based location predictions are found not only to be more precise than a common statistical approach based on observed hub visitation frequencies, but also shown to incur a much lower overhead. We further illustrate the benefit of profiling users’ mobility by discussing relevant work and suggesting applications in different types of wireless networks, including mobile ad hoc networks.
Beyond Well-designed SPARQL

SPARQL is the standard query language for RDF data. The distinctive feature of SPARQL is the OPTIONAL operator, which allows for partial answers when complete answers are not available due to lack of information. However, optional matching is computationally expensive - query answering is PSPACE-complete. The well-designed fragment of SPARQL achieves much better computational properties by restricting the use of optional matching - query answering becomes coNP-complete. However, well-designed SPARQL captures far from all real-life queries - in fact, only about half of the queries over DBpedia that use OPTIONAL are well-designed. In the present paper, we study queries outside of well-designed SPARQL. We introduce the class of weakly well-designed queries that subsumes well-designed queries and includes most common meaningful non-well-designed queries: our analysis shows that the new fragment captures about 99% of DBpedia queries with OPTIONAL. At the same time, query answering for weakly well-designed SPARQL remains coNP-complete, and our fragment is in a certain sense maximal for this complexity. We show that the fragment's expressive power is strictly in-between well-designed and full SPARQL. Finally, we provide an intuitive normal form for weakly well-designed queries and study the complexity of containment and equivalence.
Stories of family caregivers of people with dementia in Greece: Implications for counselling

Abstract A substantial body of literature has identified high rates of burden, psychological morbidity, social isolation, health and financial difficulties among dementia caregivers. The present qualitative study adopted an Interpretive Phenomenological Analysis approach in order to explore the lived experiences of dementia family caregivers within the Greek sociocultural context. The sample was purposive and consisted of 10 women dementia family caregivers from Athens and Thessaloniki. Individual in-depth interviews were conducted and analysed according to IPA. The participants’ personal accounts included themes related to ethical/existential and cultural aspects of family caregiving; changes in family relationships; impact of the caregiving experiences; sources of support and help seeking; positive and meaningful aspects of the care experience. The research findings are discussed in the context of Gilligan’s moral psychological theory, and cultural dimensions of family caregivers. Implications for counselling interventions aiming at supporting caregivers are presented.

Web based annotations Taking the web from an information publishing platform to an interactive learning environment

A retractable in-row tiller device is adapted for mounting on a movable vehicle and for tilling the ground around and between objects in a row. An outrigger arm with a rotary tiller mounted on its distal end is retracted inwardly and extended outwardly by a trapeze-type control arm which amplifies the velocity and magnitude of reciprocal motion produced by a hydraulic ram to move around and avoid objects encountered in the row. Both manually and automatically operable controls are included respectively to allow an operator to retract and extend the tiller out of and into the row as desired and to cause the tiller to be retracted and extended out of and into the row automatically upon encountering an object in the row. Manual control is also provided for the operator to override the automatic retraction control. A lift mechanism for lifting the tiller out of the ground and a rotary drive for rotating the tiller are interrelated such that the vertical lift force is variable in relation to the force required to rotate the tiller. The ratio between the lifting force and the rotary drive is adjustably variable to effect automatic depth control for ground penetration.
NGF and APP Interplay: Focus on YENPTY Motif of Amyloid Precursor Protein and Y682 Residue

NGF and APP Interplay: Focus on YENPTY Motif of Amyloid Precursor Protein and Y682 Residue Cholinergic deficits originated from NGF metabolism disruption, represent one of the early changes in Alzheimer’s disease, where abnormal deposition of β-amyloid peptide (Aβ) and phosphorylated Tau define the neuropathological hallmarks of the disorder. A failure in NGF maturation can promote pro-apoptotic pathway activation, through p75 receptor; while lack of NGF signalling can generate an atypical TrkA receptor phosphorylation resulting in neuronal cell death and Aβ toxicity. These evidences suggest a complex interaction between TrkA, p75, and Aβ, whose exact cellular mechanisms remain still elusive. Here, we provide a general overview on the current knowledge on NGF and APP interplay, focusing on the events that mediate NGF signalling impairment, and, mostly, on the role of APP Tyrosine 682 phosphorylation whose absence in APPY682G mice impairs APP/TrkA interaction and leads to cholinergicneurodegeneration.
A Service Oriented SLA Management Framework for Grid Environments

Traditionally, network Service Providers specify Service Level Agreements SLAs to guarantee service availability and performance to their customers. However, these SLAs are rather static and span a single provider domain. Thus, they are not applicable to a multi-domain environment. In this paper, the authors present a framework for automatic creation and management of SLAs in a multi-domain environment. The framework is based on Service Oriented Computing SOC and contains a collection of web service calls and modules that allow for the automatic creation, configuration, and delivery of an end-to-end SLA, created from the merging of the per-domain SLAs. This paper also presents a monitoring procedure to monitor the QoS guarantees stipulated in the SLA. The SLA establishment and monitoring procedures are tested through a Grid application scenario targeted to perform remote control and monitoring of instrument elements distributed across the Grid.
periostin Null Mice Exhibit Dwarfism, Incisor Enamel Defects, and an Early-Onset Periodontal Disease-Like Phenotype

ABSTRACT Periostin was originally identified as an osteoblast-specific factor and is highly expressed in the embryonic periosteum, cardiac valves, placenta, and periodontal ligament as well as in many adult cancerous tissues. To investigate its role during development, we generated mice that lack the periostin gene and replaced the translation start site and first exon with a lacZ reporter gene. Surprisingly, although periostin is widely expressed in many developing organs, periostin-deficient (peri lacZ ) embryos are grossly normal. Postnatally, however, ∼14% of the nulls die before weaning and all of the remaining peri lacZ nulls are severely growth retarded. Skeletal analysis revealed that trabecular bone in adult homozygous skeletons was sparse, but overall bone growth was unaffected. Furthermore, by 3 months, the nulls develop an early-onset periodontal disease-like phenotype. Unexpectedly, these mice also show a severe incisor enamel defect, although there is no apparent change in ameloblast differentiation. Significantly, placing the peri lacZ nulls on a soft diet that alleviated mechanical strain on the periodontal ligament resulted in a partial rescue of both the enamel and periodontal disease-like phenotypes. Combined, these data suggest that a healthy periodontal ligament is required for normal amelogenesis and that periostin is critically required for maintenance of the integrity of the periodontal ligament in response to mechanical stresses.
The syllable boundary in generative phonology

In Natural Generative Phonology (NGP), the only phonological rules are those which describe alternations that take place in environments that can be specified in purely phonetic terms. As indicated by Hooper, these “‘phonetic terms’ refer to phonological features (that have intrinsic phonetic content) and phonological boundaries (that have a necessary and consistent phonetic manifestation)” (1976:14). Any rule which changes phonological features in an environment described in morphosyntactic or lexical terms is not phonological but morphophonemic. Since by definition a phonological rule cannot contain non-phonetic information, this entails, among other things, the exclusion of any boundary that is not determined by phonetic means. In other words, the syllable ($) and the pause (| |) are the only boundaries which can appear in a phonological rule in NGP. The word boundary (# and ##) and the morpheme boundary (+), which are determined by syntactic and semantic means, can only appear in a morphophonemic rule.
Annexin-1 and Peptide Derivatives Are Released by Apoptotic Cells and Stimulate Phagocytosis of Apoptotic Neutrophils by Macrophages1

The resolution of inflammation is a dynamically regulated process that may be subverted in many pathological conditions. Macrophage (Mφ) phagocytic clearance of apoptotic leukocytes plays an important role in the resolution of inflammation as this process prevents the exposure of tissues at the inflammatory site to the noxious contents of lytic cells. It is increasingly appreciated that endogenously produced mediators, such as lipoxins, act as potent regulators (nanomolar range) of the phagocytic clearance of apoptotic cells. In this study, we have investigated the intriguing possibility that apoptotic cells release signals that promote their clearance by phagocytes. We report that conditioned medium from apoptotic human polymorphonuclear neutrophils (PMN), Jurkat T lymphocytes, and human mesangial cells promote phagocytosis of apoptotic PMN by Mφ and THP-1 cells differentiated to a Mφ-like phenotype. This prophagocytic activity appears to be dose dependent, sensitive to the caspase inhibitor zVAD-fmk, and is associated with actin rearrangement and release of TGF-β1, but not IL-8. The prophagocytic effect can be blocked by the formyl peptide receptor antagonist Boc2, suggesting that the prophagocytic factor(s) may interact with the lipoxin A4 receptor, FPRL-1. Using nanoelectrospray liquid chromatography mass spectrometry and immunodepletion and immunoneutralization studies, we have ascertained that annexin-1 and peptide derivatives are putative prophagocytic factors released by apoptotic cells that promote phagocytosis of apoptotic PMN by M[phi] and differentiated THP-1 cells. These data highlight the role of annexin-1 and peptide derivatives in promoting the resolution of inflammation and expand on the therapeutic anti-inflammatory potential of annexin-1.
