— This paper addresses the image representation problem in visual sensor networks. We propose a new image representation method for visual sensor networks based on compressive sensing (CS). CS is a new sampling method for sparse signals, which is able to compress the input data in the sampling process. Combining both signal sampling and data compression, CS is more capable of image representation for reducing the computation complexity in image/video encoder in visual sensor networks where computation resource is extremely limited. Since CS is more efficient for sparse signals, in our scheme, the input image is firstly decomposed into two components, i.e., dense and sparse components; then the dense component is encoded by the traditional approach (JPEG or JPEG 2000) while the sparse component is encoded by a CS technique. In order to improve the rate distortion performance, we leverage the strong correlation between dense and sparse components by using a piecewise autoregressive model to construct a prediction of the sparse component from the corresponding dense component. Given the measurements and the prediction of the sparse component as initial guess, we use projection onto convex set (POCS) to reconstruct the sparse component. Our method considerably reduces the number of random measurements needed for CS reconstruction and the decoding computational complexity, compared to the existing CS methods. In addition, our experimental results show that our method may achieves up to 2dB gain in PSNR over the existing CS based schemes, for the same number of measurements.
Automatic Classification of musical mood by content-based analysis

La musica en formato digital forma parte de nuestras vidas. Automatizar la organizacion de estos datos es un gran desafio. En esta tesis, nos centramos en la clasificacion automatica de musica a partir de la deteccion de la emocion que comunica. Para conseguirlo, proponemos modelos usando informaciones extraidas de la senal de audio mediante tecnicas de procesamiento de senales, aprendizaje automatico y recuperacion de informacion. Primero, estudiamos como los miembros de una red social utilizan etiquetas y palabras clave para describir la musica y las emociones que evoca. Con una tecnica para reducir la complejidad dimensional de este problema, encontramos un modelo para representar los estados de animo. Luego, proponemos un metodo de clasificacion automatica de emociones y detallamos los resultados para distintos tipos de clasificadores. Analizamos las contribuciones de descriptores de audio y como sus valores estan relacionados con los estados de animo, intentando encontrar explicaciones desde un punto de vista psicologico y/o musicologico. Proponemos tambien una version multimodal de nuestro algoritmo, usando las letras de canciones con un nuevo metodo de clasificacion basado en las palabras claves para distinguir categorias de emociones. Finalmente, despues de estudiar la relacion entre el estado de animo y el genero musical, presentamos un metodo usando la clasificacion automatica por genero. Mostramos que clasificadores basados en el genero obtienen mejores resultados que otros metodos estandar. A modo de recapitulacion conceptual y algoritmica, proponemos una tecnica de extraccion de reglas para entender como los algoritmos de aprendizaje automatico predicen la emocion evocada por la musica. Nuestros algoritmos han sido evaluados con datos de usuarios y en concursos de evaluacion internacionales.
A history of data-flow languages

Data-flow refers both to a language-level paradigm of computation and to a family of processor architectures based on this paradigm. This article elaborates data-flow language issues and the evolution of data-flow languages. In considering limits to the expressive power of these languages, underlying architectural issues are discussed. Although the article attempts to present a complete history of data-flow languages, it concentrates on those languages that specifically belong to this class and have been implemented for a data-flow machine. In many cases, the distinctions between issues of language semantics and machine architecture are unclear. Usually we have found that this reflects the evolution of data-flow, and the close association between language and architecture development. In some sections of the article, it may appear that there is an imbalance in the amount of detail presented when compared with other sections. This imbalance is proportional to the publications and the amount of information readily available for the topics. <<ETX>>
The Effect of the Application of a Strategy for Reading Comprehension in a Virtual Environment

The purpose of this research was to determine the effect of the application of an Integrating Instructional Strategy for Reading Comprehension (EIICL), implemented in a virtual context and designed to develop comprehension text skills on social sciences and administration of second semester students of Public Accounting and Administration Bachelor's Degree, in a Higher Education Institution. The research was conducted with a correlational design, applied to an experimental group and a control group, with before and after measurements of applying the EIICL. The results confirm that, there are significative differences between the students that made the text reading in a virtual environment with the application of EIICL, from the students that made the reading without the application of such strategy.
Characterization of the Gene Encoding the β-Lactamase of the Psychrophilic Marine Bacterium Moritella marina Strain MP-1

The β-lactamase gene (mbla) of the psychrophilic marine bacterium Moritella marina strain MP-1 was identified in a previously isolated genomic DNA fragment and it was expressed in Escherichia coli cells. The mbla gene encoded a protein consisting of 287 amino acid residues. Its predicted amino acid sequence showed approximately 50% identity with that of a number of class A β-lactamases, especially with that of CARB/PSE type of β-lactamases (carbenicillinases). E. coli transformed with the plasmid containing mbla grew on an amplicillin-containing plate at 37°C but not at 42°C, suggesting that the β-lactamase of this bacterium is heat-labile.

Profiling of Proteins Regulated by Venlafaxine during Neural Differentiation of Human Cells

Objective Antidepressants are known to positively influence several factors in patients with depressive disorders, resulting in increased neurogenesis and subsequent relief of depressive disorders. To study the effects of venlafaxine during neural differentiation at the cellular level, we looked at its effect on protein expression and regulation mechanisms during neural differentiation. Methods After exposing NCCIT cell-derived EBs to venlafaxine during differentiation (1 day and 7 days), changes in protein expression were analyzed by 2-DE and MALDI-TOF MS analysis. Gene levels of proteins regulated by venlafaxine were analyzed by real-time RT-PCR. Results Treatment with venlafaxine decreased expression of prolyl 4-hydroxylase (P4HB), ubiquitin-conjugating enzyme E2K (HIP2) and plastin 3 (T-plastin), and up-regulated expression of growth factor beta-3 (TGF-β3), dihydropyrimidinase-like 3 (DPYSL3), and pyruvate kinase (PKM) after differentiation for 1 and 7 days. In cells exposed to venlafaxine, the mRNA expression patterns of HIP2 and PKM, which function as negative and positive regulators of differentiation and neuronal survival, respectively, were consistent with the observed changes in protein expression. Conclusion Our findings may contribute to improve understanding of molecular mechanism of venlafaxine.
3D reconstruction of articulated objects from uncalibrated images

The goal of computing realistic 3-D models from image sequences is still a challenging problem. In recent years the demand for realistic reconstruction and modeling of objects and human bodies is increasing both for animation and medical applications. In this paper a system for the reconstruction of 3-D models of articulated objects, like human bodies, from uncalibrated images is presented. The scene is seen from different viewpoints and no pre-set knowledge is considered. To extract precise 3-D information from imagery, a calibration procedure must be performed. Therefore, first a camera calibration with Direct Linear Transformation (DLT) is done assuming few control points on the subject. The initial approximations of the interior and exterior orientation computed with DLT are then improved in a general photogrammetric bundle adjustment with self-calibration. Additionally a stereo matching process based on least squares matching extracts a dense set of image correspondences from the sequence. Finally a 3-D point cloud is computed by forward intersection using the calibration data and the matched points. The resulting 3-D model of human body is presented.
Outcome of penicillin-nonsusceptible Streptococcus pneumoniae meningitis: a nested case-control study

Background. There are few data comparing the clinical features, management and outcome of penicillin-nonsusceptible Streptococcus pneumoniae (PNSP) meningitis patients with penicillin-susceptible S. pneumoniae (PSSP) meningitis patients. Methods. We performed a retrospective, nested case-control study comparing cases with PNSP meningitis with controls with PSSP meningitis obtained from the Immunization Monitoring Program, Active (IMPACT) cross-Canada surveillance study of invasive S. pneumoniae infections. Results. There were 30 PNSP meningitis cases (10.1% of total) and 45 PSSP meningitis controls from 6 centers obtained from 297 meningitis cases in the IMPACT database from 1991 through 1999. Vancomycin was used for empiric therapy in no cases and controls in 1991 to 1993 and in all cases in 1999. A third generation cephalosporin was used in 93.3% of confirmed PNSP cases, and 70.0% also received vancomycin and/or rifampin. Penicillin was used in 66.7% of confirmed PSSP cases. PNSP cases were more likely than PSSP controls to have a second lumbar puncture (odds ratio, 4.1;P = 0.01). PNSP cases were treated with intravenous antibiotics for an average of 15.6 days compared with 12.3 days for controls (P = 0.04). Among PNSP cases, those patients who did not receive empiric vancomycin were treated with intravenous antibiotics for an average of 18.5 days compared with 12.0 days for those who did receive empiric vancomycin (P = 0.04). The overall mortality was 5.3%, and 36.6% of survivors had ≥1 neurologic sequelae, including 19.7% with hearing loss. In multivariate statistical models, PNSP was not a risk factor for intensive care unit admission or neurologic sequelae. Conclusions. Management of suspected bacterial meningitis and confirmed S. pneumoniae meningitis in Canadian children changed in the past decade. Treatment of PNSP meningitis is significantly different from that for PSSP meningitis. These changes have occurred in response to the emergence of PNSP in Canada. Neurologic sequelae remain common after S. pneumoniae meningitis, but there are no differences between PNSP cases and PSSP cases.

Investigating the interface of the investment model and adult attachment theory

We examined whether the extent to which individuals accord importance to components of the investment model varies by attachment. In Study 1, rewards and costs in a hypothetical relationship were experimentally manipulated, and participants (single and dating undergraduates) reported perceptions of rewards, costs, and satisfaction. In Study 2, investments and alternative quality were manipulated, and participants reported perceptions of investments, alternatives, satisfaction, and commitment. Study 1 revealed that relative to others, individuals high in both anxiety and avoidance (i.e., fearful) accord less weight to rewards when determining satisfaction. Study 2 revealed that relative to others, individuals low in anxiety and high in avoidance (i.e., dismissing) accord more weight to investments and alternatives, and less weight to satisfaction when determining commitment.

Developmental changes in the localization of activated C‐JUN N‐terminal kinase (JNK/SAPK) in the chick spinal cord

To examine the role of c‐Jun N‐terminal kinase (JNK/SAPK) in the developing nervous system of vertebrates, the localization of an active form of JNK, phosphorylated JNK (p‐JNK), was studied in the lumbosacral spinal cord of the chick embryo. We also examined the localization of phosphorylated neurofilaments (NFs, potential targets of p‐JNK) and cyclin‐dependent kinase 5 (Cdk5), which is known to phosphorylate cytoskeletal proteins, including NFs, and compared their expression with that of p‐JNK. Additionally, the localization of phosphorylated forms of c‐Jun and ATF‐2 was compared with that of p‐JNK. On embryonic day 3 (E3), the expression of p‐JNK was observed in regions containing early‐projecting axons. Axons in these regions also expressed phosphorylated NFs. Subsequently, on E5 and E8, the expression of both p‐JNK and phosphorylated NFs increased concomitantly in the axonal tracts in the spinal white matter. Thus, white matter expressed both p‐JNK and phosphorylated NFs, whereas there was only weak expression of Cdk5. By E13, the spinal cord expression pattern of p‐JNK and phosphorylated NFs had changed compared to earlier ages. Although phosphorylated NFs were still expressed in the white matter, the expression of p‐JNK was decreased in axons in the white matter, whereas strong p‐JNK expression appeared in cell nuclei in the gray matter. In summary, the present study revealed that the localization of p‐JNK in the spinal cord changes dramatically from axons to cell nuclei during development, suggesting multiple roles of p‐JNK, depending on the developmental age.

Towards a Low Power Virtual Machine forWireless Sensor Network Motes

Virtual machines (VMs) have been proposed as an efficient programming model for wireless sensor network (WSN) devices. However, the processing overhead required for VM execution has a significant impact on the power consumption and battery lifetime of these devices. This paper analyses the sources of power consumption in the Mate VM for WSNs. The paper proposes a generalised processor architecture allowing for hardware acceleration of VM execution. The paper proposes a number of hardware accelerators for Mate VM execution and assesses their effectiveness
The Perturbation Bound for the Spectral Radius of a Nonnegative Tensor

We study the perturbation bound for the spectral radius of an mth-order n-dimensional nonnegative tensor . The main contribution of this paper is to show that when is perturbed to a nonnegative tensor by , the absolute difference between the spectral radii of and is bounded by the largest magnitude of the ratio of the ith component of and the ith component , where is an eigenvector associated with the largest eigenvalue of in magnitude and its entries are positive. We further derive the bound in terms of the entries of only when is not known in advance. Based on the perturbation analysis, we make use of the NQZ algorithm to estimate the spectral radius of a nonnegative tensor in general. On the other hand, we study the backward error matrix and obtain its smallest error bound for its perturbed largest eigenvalue and associated eigenvector of an irreducible nonnegative tensor. Based on the backward error analysis, we can estimate the stability of computation of the largest eigenvalue of an irreducible nonnegative tensor by the NQZ algorithm. Numerical examples are presented to illustrate the theoretical results of our perturbation analysis.

Histone Modifications at the Blastocyst Axin1Fu Locus Mark the Heritability of In Vitro Culture-Induced Epigenetic Alterations in Mice1

For epigenetic phenotypes to be passed on from one generation to the next, it is required that epigenetic marks between generations are not cleared during the two stages of epigenetic reprogramming: mammalian gametogenesis and preimplantation development. The molecular nature of the chromatin marks involved in these events is unknown. Using the epigenetically inherited allele Axin1Fu (the result of a retrotransposon insertion upstream of the Axin1 gene) we sought to establish the heritable mark during early embryonic development that determines transgenerational epigenetic inheritance and to examine a possible shift in the expression of this epiallele in future progeny induced by in vitro culture (IVC). To identify the heritable mark we analyzed 1) the level of DNA methylation shown by the Axin1Fu allele in sperm and embryos at blastocysts stage and 2) the histone marks (H3K4 me2, H3K9 me3, H3K9 ac, and H4K20 me3) present at the blastocyst stage at the specific Axin1Fu locus. According to our data, histone H3K4 me2 and H3K9 ac mark the differences between the Axin1Fu penetrant and the silent locus during the first period of demethylation of the preimplantation development. Moreover, suboptimal IVC (reported to produce epigenetic alterations in embryos) and the histone deacetylase inhibitor trichostatin A affect the postnatal expression of this epigenetically sensitive allele through histone modifications during early development. This finding indicates that altered histone modifications during preimplantation can drive altered gene expression later on in development.

Injection drug use and the hepatitis C virus: Considerations for a targeted treatment approach-The case study of Canada

Infection with the hepatitis C virus (HCV) is a major public health burden in Canada and globally. The literature shows that injection drug use is currently the primary transmission route for HCV, and that a majority of injection drug users (IDUs) are currently infected with HCV in Canada. This article first reviews the burden of HCV within IDU populations and the transmission risks and the treatment implications speicifc to IDUs. Traditionally, IDUs have been excluded from HCV treatment unless abstaining from illicit drug use. However, recent research suggests that categorical exclusion is not medically necessary. A series of key questions about the feasibility of offering HCV treatment to IDUs in the specific Canadian context are considered, including concerns related to the motivation of treatment for IDUs, treatment delivery, treatment side effects, HCV reinfection, and the social environment. The article concludes that treatment of HCV-infected illicit drug users is both feasible and may be necessary to reduce transmission and adverse outcomes in this high-risk population.
Regulation of hypothalamic magnocellular neuropeptides and their mRNAs in the Brattleboro rat: coordinate responses to further osmotic challenge

A paradigm was developed for the chronic osmotic stimulation of homozygous diabetes insipidus rats of the Brattleboro strain, a strain that fails to synthesize vasopressin. This study examines the adaptation of 2 sets of coexisting peptide hormone magnocellular neurons in the hypothalamoneurohypophyseal system (HNS) of Long Evans (LE), Brattleboro heterozygote (HZ), and Brattleboro homozygote (DI) rats: (1) the arginine8-vasopressin (AVP)/dynorphin (DYN) neurons, and (2) the oxytocin (OT)/cholecystokinin (CCK8) neurons of the paraventricular and supraoptic nuclei, which project to the posterior pituitary. The regimen of chronic intermittent salt-loading (CISL) involved the replacement of 2% saline for normal drinking water for 18 hr/d. This protocol effectively increased plasma levels of AVP and OT in LE and HZ rats, oxytocin in DI rats, and maintained the posterior pituitary in a state depleted of AVP, OT, CCK, and peptides derived from pro-dynorphin: DYN A 1–17, DYN A 1–8, and DYN B 1–13. The ratio of pituitary DYN A 1–17 to DYN A 1–8 content in DI rats or in LE, HZ, and DI rats following 6 d of CISL suggests a preferential release of DYN A 1–17 during periods of chronic secretory activity. In response to chronic secretory activity, mRNAs for AVP, OT, DYN, and CCK increased 1.5–2-fold in all 3 AVP rat strains, with mRNAs for coexisting peptide hormones displaying parallel increases. Mutant AVP mRNA in the DI rat was expressed at very low levels and DYN mRNA in very high levels, with each of these mRNAs continuing to be regulated by CISL in a normal manner. These results suggest a regulatory relationship between AVP and OT neurons, in which vasopressin neurons are feedback-regulated by AVP, most likely via plasma osmolarity, and that oxytocin neurons are modulated by peptides derived from pro-dynorphin.
