MODELLING THE NORTHERN HUMBOLDT CURRENT ECOSYSTEM MODELADO DEL NORTE DEL ECOSISTEMA DE LA CORRIENTE DE HUMBOLDT

with the Regional Oceanic Modeling System (ROMS). The oceanic model simulated the climatological and interannual variation of temperature, salinity and currents (Penven et al. 2005). Fig. 1 shows a climatological simulation of sea surface temperature of Peru, emphasizing cold waters from coastal upwelling and warm waters from the north and offshore. This model will be used as boundary conditions for nested models of several bays along the Peruvian coast, in order to assess the ecotoxicological effects of anthropogenic pollutants. The biogeochemical processes are simulated using the outputs of the physical ROMS model, coupled to the Pelagic Interaction Scheme for Carbon and Ecosystem Studies (PISCES) biogeochemical model, which includes several components such as nutrients, phytoplankton, zooplankton, detritus, etc. (Aumont et al. 2003). I n t u r n , t h e o u t p u t s o f t h e biogeochemical model can be used to feed a biological Individual Based Model (IBM) such as ICHTHYOP (Previmer 2008, Brochier et al. 2008). These models can simulate the influence of El Nino event on reducing nutrient concentrations, primary production, and consequently, affecting early life stages of pelagic fishes.

Des Communs « à double révolution »

La question des Communs fait un retour remarque sur la scene intellectuelle et politique en remettant en cause tant notre rapport addictif a la propriete que nombre de constructions institutionnelles (l’Etat, le droit, le Marche) que nous croyons naivement acquises et universalisees. Pour en comprendre les enjeux, il faut tout d’abord en saisir l’originalite initiale et radicale par le detour anthropologique d’experiences outre-mer puis apprecier ses modes particuliers de confrontation contemporaine au marche generalise et capitaliste. Nous vivons ainsi une double revolution, comme redecouverte « copernicienne » de relations precapitalistes et comme rupture possible avec l’ordre proprietariste suggerant un dedoublement fonctionnel de la notion de Communs.
Combined analysis of time&frequency synchronization error for BiSAR

Signal model has great significance to time and phase synchronization research in a bistatic radar. In prevenient research, time synchronization and phase synchronization are investigated separately and their coupling relation has not been investigated. This paper introduces a bistatic radar signal model according to system's composition and operation procedure. From the radar operation principle, origin of time and phase synchronization in bistatic radar is revealed and their coupling relation is derived in theory.
Circadian Periodicity of Intestinal Na+/Glucose Cotransporter 1 mRNA Levels Is Transcriptionally Regulated*

Intestinal expression of the high affinity Na+/glucose cotransporter 1 (SGLT1), which absorbs dietary glucose and galactose, exhibits both circadian periodicity in its activity and induction by dietary carbohydrate. Because the daily variation in SGLT1 activity is established by the feeding schedule (whether ad libitum or imposed) and persists in the absence of food, this variation has been described as anticipatory. To delineate the mechanisms regulating SGLT1, its expression was examined in rats maintained in a 12-h photoperiod with free access to chow. SGLT1 mRNA levels varied significantly, with the maximum abundance occurring near the onset of dark and the minimum near the onset of light. The SGLT1 transcription rate was 7-fold higher in the morning (1000–1100 h) than in the afternoon (1600–1700 h). An element for hepatocyte nuclear factor 1 (HNF-1) was identified in the SGLT1 promoter that formed different complexes with small intestinal nuclear extracts, depending on the time when the source animal was killed. Serological tests indicated that HNF-1α was present in complexes throughout the day, while HNF-1β binding exhibited circadian periodicity. We propose that exchange of HNF-1 dimerization partners contributes to circadian changes in SGLT1 transcription. Because SGLT1 mRNA levels also varied in rhesus monkeys (offset by approximately one-half day from rats), a similar mechanism appears to be present in primates.

Identification of British English regional accents using fusion of i-vector and multi-accent phonotactic systems

The para-linguistic information in a speech signal includes clues to the geographical and social background of the speaker. This paper is concerned with recognition of the 14 regional accents of British English. For Accent Identiﬁcation (AID), acoustic methods exploit differences between the distributions of sounds, while phonotactic approaches exploit the sequences in which these sounds occur. We demonstrate these methods are good complements for each other and use their confusion matrices for further analysis. Our relatively simple i-vector and phonotactic fused system with recognition accuracy of 84.87% outperforms the i-vector fused results reported in literature, by 4.7%. Further analysis on distribution of British English accents has been carried out by analyzing the low dimensional representation of i-vector AID feature space.
Aprendizaje relacional de distintas modalidades estimulares. Implicación de la conducta verbal

La derivacion de relaciones constituye uno de los temas mas importantes en los ultimos anos dentro del Analisis Experimental del Comportamiento, y se refiere a la aparicion de relaciones entre estimulos sin necesidad de un entrenamiento directo (Sidman y T ailby, 1982; Sidman, 1994). Una de las principales lineas de investigacion dentro de este tema es aquella que ha analizado la influencia de la conducta verbal sobre las relaciones derivadas en sujetos que ya tienen un repertorio verbal y de derivacion, aspecto que resulta polemico y sobre el que no existe consenso a nivel conceptual ni metodologico. Por tanto, el objetivo fundamental de esta tesis es el de aportar nuevas evidencias sobre la formacion y seguimiento de reglas verbales en el aprendizaje y derivacion de relaciones arbitrarias en sujetos adultos, y tralar de determinar de manera detallada el efecto que tipos de reglas particulares pueden tener a la hora de facilitar o dificultar esta derivacion. Para ello se llevo a cabo una serie de tres estudios. El primer estudio estaba dedicado a desarrollar una tarea experimental controlada que permitiera demostrar el fenomeno de la derivacion empleando estimulos olfativos y visuales, y constaba de dos experimentos. Durante el Experimento 1, se replico y extendio un estudio previo para demostrar esta derivacion (Annett y Leslie, 1995) mientras que durante el Experimento 2 se realizo una modificacion de la tarea desarrollada para resolver algunas amenazas potenciales a la validez. El segundo estudio tenia como objetivos aplicar la metodologia del analisis de protocolos para obtener informes verbales concurrentes a la tarea (Ericsson y Simon, 1980, 1986) e implementar los controles del metodo del silent dog para demostrar que esos informes se corresponden funcional mente con el comportamiento verbal de los sujetos durante esa tarea (Hayes, 1986). Para ello, a lo largo del Experimento 3 se compararon las eje
Cooperative multiuser modulation classification in multipath channels via expectation-maximization

With the advent of cognitive radio (CR) and dynamic spectrum access techniques, where multiple signals may coexist within the same frequency band, multiuser modulation classification problem becomes a vital issue, which has not been sufficiently investigated. In this paper, we consider a cooperative multiuser modulation classification problem, in the presence of unknown multipath channels. A likelihood-based (LB) classifier using the expectation-maximization (EM) algorithm is proposed, which enables to find the maximum likelihood estimates (MLEs) iteratively. Numerical results show that the proposed algorithm achieves significant improvement on the classification performance with a small number of samples when compared to the conventional methods, which demonstrates its reliability and efficiency of identifying modulations of multiple users under the multipath scenarios.
Analytic proof systems for classical and modal logics of restricted quantification

This thesis is a study of the relationship between proof systems for propositional logic and for logics of restricted quantification incorporating restriction theories. Such logics are suitable for the study of special purpose reasoning as part of a larger system, an important research topic in automated reasoning. Also, modal and sorted logics can be expressed in this way. Thus, results on restricted quantification apply to a wide range of useful logics. D'Agostino's "expansion systems" are used to generalise results to apply to a variety of tableau-like propositional proof systems. A certain class of propositional expansion systems is defined, and extended for restricted quantification in two different ways. The less general, but more useful, extension is proved sound and complete provided that the restriction theory can be expressed as a set of definite Horn clauses. In the definite clauses case, the result is used to present a generalisation of Wallen's matrix characterisations of validity for modal logics. The use of restricted quantification enables more logics to be covered than Wallen did, and the use of expansion systems allows analogues of matrices to be defined for proof systems other than tableaux. To derive the results on matrices, the calculi for restricted quantification are made weaker, and so can be unsound for some restriction theories. However, much greater order independence of rule applications is obtained, and the weakening is sound if one of two new conditions introduced here hold, namely "alphabetical monotonicity" or "non-vacuity". Alphabetical monotonicity or non-vacuity are shown to hold for a range of interesting restriction theories associated with order sorted logics and some modal logics. I also show that if non-vacuity holds, then instantiation in restricted quantification can be completely separated from propositional reasoning. The major problem left open by this thesis is whether analogues of the previous matrix characterisations can be produced based on the proof systems introduced for nondefinite clause restriction theories.
Leucine does not affect mechanistic target of rapamycin complex 1 assembly but is required for maximal ribosomal protein s6 kinase 1 activity in human skeletal muscle following resistance exercise

We examined how the stimulatory effect of leucine on the mechanistic target of rapamycin complex 1 (mTORC1) pathway is affected by the presence of the remaining essential amino acids (EAAs). Nine male subjects performed resistance exercise on 4 occasions and were randomly supplied EAAs with leucine, EAAs without leucine (EAA‐Leu), leucine alone, or flavored water (placebo; control). Muscle biopsies were taken from the vastus lateralis before and 60 and 90 min after exercise. Biopsies were analyzed for protein phosphorylation, kinase activity, protein‐protein interactions, amino acid concentrations, and tracer incorporation. Leucine alone stimulated ribosomal protein s6 kinase 1 (S6K1) phosphorylation ∼280% more than placebo and EAA‐Leu after exercise. Moreover, this response was enhanced by 60‐75% after intake of EAAs compared with that of leucine alone (P < 0.05). Kinase activity of S6K1 reflected that of S6K1 phosphorylation; 60 min after exercise, the activity was elevated 3.3‐ and 4.2‐fold with intake of leucine alone and with EAAs, respectively (P < 0.05). The interaction between mammalian target of rapamycin and regulatory‐associated protein of mammalian target of rapamycin was unaltered in response to both resistance exercise and amino acid provision. Leucine alone stimulates mTORC1 signaling, although this response is enhanced by other EAAs and does not appear to be caused by alterations in mTORC1 assembly. —Apró, W. , Moberg, M. , Hamilton, D.

[Autofluorescence imaging of the macula].

Visualization of the retinal pigment epithelium (RPE) in vivo has proven difficult for various reasons, including the optical properties of the eye and the small size of the cellular elements, forming a single layer between the neurosensory retina and Bruch's membrane. With the advent of scanning laser ophthalmoscopy it is now possible to image topographic distribution and intensity fundus autofluorescence derived from accumulations of lipofuscin granules in RPE cells. Excessive lipofuscin storage in the RPE cytoplasm occurs not only in association with age but also with many hereditary and degenerative retinal diseases including age-related macular degeneration, Stargardt disease, Best disease, and pattern dystrophies. Lipofuscin in the RPE derives mainly from incomplete degradation of phagocytosed distal segments of photoreceptor outer segments, and is composed of various biomolecules including lipids, protein, and retinoids. Some of its constituents have recently been shown to possess toxic properties in vitro and may play a pathophysiological role in diseases such as age-related macular degeneration.Visualizing lipofuscin in vivo may help to better understand the significance of these metabolic alterations in the pathogenesis of retinal disorders. In addition,fundus autofluorescence imaging can be useful in the preclinical diagnosis of hereditary retinal disease. Dynamic alterations of intrinsic RPE fluorescence change may be applicable for monitoring effects at the level of the RPE of novel therapeutic modalities. Furthermore, identification of high-risk characteristics in patients with age-related macular degeneration with this technique may be helpful for indicating and adjusting future therapies.
PathoSpotter: um sistema para classificação de glomerulopatias a partir de imagens histológicas renais

A realizacao do diagnostico preciso a partir de imagens histologicas requer medicos patologistas com vasta experiencia pratica, pois as caracteristicas dessas imagens conduzem a uma analise subjetiva que muitas vezes dificultam a exatidao do diagnostico. Sistemas que auxiliam a obtencao de melhores diagnosticos podem minimizar duvidas e melhorar a qualidade dos diagnosticos, influenciando no aumento da eficacia dos tratamentos medicos. Este trabalho descreve a pesquisa e o desenvolvimento do PathoSpotter, um sistema computacional para auxilio na identificacao de patologias a partir de imagens histologicas. O PathoSpotter se propoe a reduzir a carencia de trabalhos de apoio ao diagnostico histopatologico das doencas renais, ja que muito tem sido feito na area de neoplasias, mas ha pouco material publicado em relacao a Patologia Digital aplicada a nefrologia ou hepatologia. Nosso objetivo neste trabalho foi aplicar o PathoSpotter na classificacao das glomerulopatias proliferativas, que e uma familia de doencas primarias que afetam os rins. O trabalho se baseou em um conjunto de dados composto por 811 imagens histologicas de glomerulos, e foram utilizadas tecnicas classicas de processamento de imagens e histopatologia digital. O PathoSpotter apresentou um desempenho de 88,4% de acuracia, resultado similar ao de outros trabalhos de Patologia Digital que podem ser encontrados na literatura especializada.
A class of multistage conference switching networks for group communication

Many emerging network applications, such as teleconferencing and information services, require group communication, in which messages from one or more sender(s) are delivered to a large number of receivers. We consider efficient network support for a key type of group communication, conferencing. A conference refers to a group of members in a network who communicate with each other within the group. In our recent work (Yang, 2001), we proposed a design for a conference network which can support multiple disjoint conferences. The major component of the network is an enhanced multistage switching network which interconnects switch modules with fan-in and fan-out capability. The multistage network used is modified from an indirect binary cube network by relaying all internal outputs at each stage through multiplexers to the outputs of the network. Each conference is realized in an indirect binary cube-like subnetwork depending on its location. A natural question here is: Can we directly adopt a class of multistage networks such as a baseline, an omega, or an indirect binary cube network to obtain a conference network with more regular network structure, simpler self-routing algorithm and less hardware cost? This paper aims to answer this question. The key issue in designing a conference network is to determine the multiplicity of routing conflicts, which is the maximum number of conflict parties competing a single interstage link when multiple disjoint conferences simultaneously present in the network.
Behavior Prediction InThe-Wild

In this paper, the problem of audio-visual behavior prediction in-the-wild is addressed. In this context, both audiovisual descriptors of behavioral cues (features) and continuoustime real-valued characterizations of behavior (annotations) are (possibly) corrupted by non-Gaussian noise of large magnitude. The modeling assumption behind the proposed framework is that naturalistic affect and behavior captured in audiovisual episodes are smoothly-varying dynamic phenomena and thus the hidden temporal dynamics can be modeled as a generative auto-regressive process. Consequently, continuoustime real-valued characterizations of behavior (annotations) are postulated to be outputs of a low-complexity (i.e., loworder) time-invariant Linear Dynamical System (LDS) when descriptors of behavioral cues (features) act as inputs. To learn the parameters of the LDS, a recently proposed spectral method that relies on Hankel-rank minimization is adopted. Experimental evaluation on a challenging database recorded in the wild demonstrate the effectiveness of the proposed approach in behavior prediction.
P 4 P : Proactive Provider Participation for P 2 P ∗

As peer-to-peer (P2P) emerges as a new paradigm for scalable network application design, it is also posing significant new challe nges to achieving efficient and fair utilization of network resources. In p articular, without the ability to explicitly communicate with network prov iders, P2P applications may consume too much bandwidth than the network p rovider can afford, trigering network provider reaction. Furthermore , P2P applications depend mainly on inefficient network inference and networkoblivious peering, leading to potential inefficiencies for both P2P applic ations and network providers. In this paper, we propose a simple, light-weight architecture called P4P to allow more effective cooperative traffic control betw en applications and network providers. We conduct not only extensive simula tions but also real-life experiments with three major ISPs to demonstrate the effectiveness and feasibility of P4P.
High pretreatment serum concentration of basic fibroblast growth factor is a predictor of poor prognosis in small cell lung cancer.

Basic fibroblast growth factor (bFGF) is a secreted multifunctional cytokine and a potent stimulator of angiogenesis. We measured bFGF concentrations from serum samples taken from 103 patients with small cell lung cancer at the time of diagnosis. Serum concentration of bFGF (S-bFGF) ranged from undetectable to 54 pg/ml (median, 6 pg/ml). S-bFGF was not associated with age, sex, performance status, or stage. A high pretreatment S-bFGF was associated with poor overall survival. The 1- and 2-year survival rates of the patients within the highest quartile of S-bFGF (>or=17 pg/ml) were only 26% and 11%, respectively, in contrast to the 49% and 20% 1- and 2-year survival rates of those patients with S-bFGF < 17 pg/ml (P = 0.013). The 1- and 2-year survival rates of the patients with extensive-stage disease were 33% and 10%, respectively (P = 0.0091). Interestingly, S-bFGF provided additional prognostic information to the stage because the 1- and 2-year survival rates of patients with extensive-stage disease and a high S-bFGF (>or=17 pg/ml) were as low as 16% and 5%, respectively (P = 0.0026). Similarly, in the multivariate model of survival analysis, patients with both extensive-stage disease and a high S-bFGF (>or=17 pg/ml) were found to have a particularly poor prognosis (relative risk of death, 2.1; 95% confidence interval, 1.2-3.6; P = 0.0057). We conclude that a high S-bFGF at diagnosis is associated with poor outcome in small cell lung cancer, possibly reflecting active angiogenesis and rapid tumor growth, and may complement prognostic information obtained by staging.
The linear fitting Kalman filter for nonlinear tracking

Dynamic estimation in various synthetic aperture radar (SAR) applications often involves nonlinear models. The first-order Taylor approximation is usually used to linearize the nonlinear functions to perform estimation efficiently. However, the error generated by the first-order Taylor approximation cannot be negligible when dynamic systems are high nonlinearity or with large input errors. This paper proposes a linearization method by minimizing the difference between the nonlinear function and its linear approximation, and yields a better linear fitting function. A Kalman filter based on this principle is suggested. Simulation tests are conducted among the proposed linear fitting Kalman filter (LFKF), the extended Kalman filter (EKF) and the unscented Kalman filter (UKF). The results show that the LFKF obviously outperforms the EKF which uses the first-order Taylor approximation, and the LFKF can achieve similar estimation accuracy of the UKF with less computational cost.
