A low-noise fully differential recycling folded cascode neural amplifier

This paper describes the design of an amplifier to be used as part of a neural recording system. The architecture of this amplifier was based on a fully differential folded cascode (FDFC) amplifier and adapted to a recycling architecture which reuses currents in order to achieve better performance. Furthermore, as we are designing a neural amplifier, a low input-referred noise is required due to the small amplitude of neural signals, as they could be as small as 1 μV. The recycling architecture was optimized for low-noise, and simulated in AMS 0.35 μm CMOS process. An input-referred noise of 1.16 μVrms was achieved while consuming 66.03 μW from a 3.3 V supply, which corresponds to NEF=2.58. The open-loop gain of the amplifier is 111.25 dB and the closed-loop gain is 42.10 dB with a bandwidth of 6.02 kHz.
Analysis of the Spreading Influence Variations for Online Social Users under Attacks

Identifying influential spreaders in online social networks (OSNs) has long been an important but difficult problem to be addressed. Distinguished from previous works that mainly focused on the stationary features of users' influence, we systematically study the variations of users' spreading capability given the fact that influential spreaders are more likely to be the targets of various cyber attacks in real OSNs. In order to rank users' spreading capability, we adopt the $k$-shell structure which assigns a coreness index, $k_s$ , to each user. We find that users' spreading capability can considerably change when attacks occur in specific structures of OSNs. Generally, if the OSN structure is assortative (i.e., large-degree nodes preferably connect to nodes with large degree), users' spreading capability is resilient to attacks. However, if the OSN structure is disassortative (i.e., large-degree nodes preferably connect to nodes with small degree), users' spreading capability decreases significantly under attacks. We further carried out a series of empirical studies in real OSN datasets to disclose the causation of the variations caused by attacks. The research presented in this paper benefit decision makers to protect the propagation in the case of product promotion or prevent the diffusion like rumor.

Assessment of Radiation and Heavy Metals Risk due to the Dietary Intake of Marine Fishes (Rastrelliger kanagurta) from the Straits of Malacca

The environment of the Straits of Malacca receives pollution as a result of various industrial and anthropogenic sources, making systematic studies crucial in determining the prevailing water quality. Present study concerns concentrations of natural radionuclides and heavy metals in marine fish (Rastrelliger kanagurta) collected from the Straits of Malacca, since aquatic stock form an important source of the daily diet of the surrouding populace. Assessment was made of the concentrations of key indicator radionuclides (226Ra, 232Th, 40K) and heavy metals (As, Mn, Fe, Cr, Ni, Zn, Cu, Co, Sr, Al, Hg and Pb) together with various radiation indices linked to the consumption of seafish. The annual effective dose for all detected radionuclides for all study locations has been found to be within UNSCEAR acceptable limits as has the associated life-time cancer risk. The overall contamination of the sampled fish from heavy metals was also found to be within limits of tolerance.
“Synchrony” as a way to choose an interacting partner

Robots are poised to fill a growing number of roles in todays society. In future, we could have robots expected to behave as companion in our home, offices etc. Moving to social robotics imply to address several issues related to human-robot interactions for instance, how the robot can develop an attentional mechanism and select an interacting agent among several interactants. We took our inspiration from neurobiological and psychological studies suggesting that synchrony is an essential parameter for social interaction. We assumed that synchrony detection could be used for intitiating human robot interaction. We present a neural network architecture able to focus the attention of the robot and to select an interacting partner on the basis of synchrony detection.
A Multi-Dimensional Examination of Marketing Journal Rankings by North American Academics

This paper extends the journal ranking debate by developing weighted multi-dimensional perceptual rankings based on respondents’ evaluation of a journals’ prestige, contribution to theory, contribution to practice and contribution to teaching. Spearman correlations indicate that journal rankings based on each of the evaluative criteria are statistically significantly correlated for all pairs of criteria, other than teaching and theory. The multi-dimensional evaluation is also statistically significantly correlated to all individual criteria, other than the teaching dimension. A cluster analysis of the journals using the four evaluative criteria identified that there are three groupings of journals: A, B and C. In most cases, A journals are evaluated as performing better than B journals on each of evaluative criteria other than for the contribution to teaching where there are no difference in perceptions between groups. B journals are viewed to perform better than C journals on prestige, contribution to practice and contribution to teaching, but not based on their prestige of weighed evaluation. This suggests that there are differences in how academics view each group of journals, although these differences do seem to vary based on the grouping being considered (i.e., A, B, or C).
Exact beta function and glueball spectrum in large-N Yang Mills theory

In the pure large-N Yang-Mills theory there is a quasi-BPS sector that is exactly solvable at large N. It follows an exact beta function and the glueball spectrum in this sector. The main technical tool is a new holomorphic loop equation for quasi-BPS Wilson loops, that occurs as a non-supersymmetric analogue of Dijkgraaf-Vafa holomorphic loop equation for the glueball superpotential of n=1 SUSY gauge theories. The new holomorphic loop equation is localized, i.e. reduced to a critical equation, by a deformation of the loop that is a vanishing boundary in homology, somehow in analogy with Witten's cohomological localization by a coboundary deformation in SUSY gauge theories.
[Impact of hydrogen sulfide donor on experimental pulmonary hypertension induced by high pulmonary flow and endogenous carbon monoxide/heme oxygenase pathway].

OBJECTIVE To explore the possible impact of hydrogen sulfide donor-NaHS (sodium hydrosulfide) on experimental pulmonary artery structural remodeling induced by high pulmonary flow and endogenous carbon monoxide/heme oxygenase pathway. METHODS Thirty-two male SD rats were randomly divided into shunt group (n=8), shunt+NaHS group (n=8), sham group (n=8) and sham+NaHS group (n=8). Rats in shunt group and shunt+NaHS group were subjected to an abdominal aorta-inferior vena cava shunt to create an animal model of high pulmonary flow. In the sham group and sham+NaHS group, rats experienced the same experimental processes except the shunting procedure. After 11 weeks of operation, systolic pulmonary artery pressure (SPAP) was detected using a right cardiac catheterization procedure. The percentage of muscularized artery (MA), partly muscularized artery (PMA) and non-muscularized artery (NMA) was calculated. Relative medial thickness (RMT) and relative medial area (RMA) of MA were observed under optical-microscope, respectively. The ultra-structure of pulmonary arteries was observed under electro-microscope. Lung tissue carbon monoxide (CO) was measured. Western-blot was used to analyze lung tissue heme oxygenase (HO-1) protein expression. RESULTS After 11 weeks of shunt, compared with sham group, SPAP in shunt group increased by 48.6%. The percentages of MA and PMA increased by 74.2% and 90.9%, but the percentage of NMA decreased 32.2%, respectively, in rats of shunt group as compared with that of sham group. In contrast to those in sham group, RMT and RMA in median MA and small MA of rats in shunt group increased by 83.6%, 86.9%, and 74.4%, 39.9%, respectively. Ultra-structural changes in rats of shunt group showed that endothelial cells were swollen and denatured, inner elastic membrane became irregular, and smooth muscle cells became synthetic phenotype. The sham and shunt groups did not differ significantly in CO and HO-1 protein expression of lung tissues. In contrast to that of shunt group, SPAP in rats of shunt+NaHS group decreased by 19.8%. The percentages of MA and PMA decreased by 14.4% and 12.2%, but the percentage of NMA increased 13.9%, respectively, in rats of shunt+NaHS group as compared with that of shunt group. In contrast to those of shunt group, RMT and RMA in median MA and small MA in rats of shunt+NaHS group decreased by 16.2%, 14.3%, and 26.9%, 14.3%, respectively. For rats in shunt+NaHS group ultra-structural changes showed that flat endothelial cells, inner elastic membrane became regular, and smooth muscle cells were contractile phenotype. The content of CO increased by 25.5% and the HO-1 protein expression increased by 114.3% in shunt+NaHS group as compared with those of shunt group. CONCLUSION NaHS might prevent pulmonary hypertension and pulmonary artery structural remodeling induced by high pulmonary flow, and its mechanism might be associated with the changes in endogenous CO/HO pathway.
Interventions to Improve Antipsychotic Medication Adherence: Review of Recent Literature

Antipsychotic nonadherence is an important barrier to the successful treatment of schizophrenia and can lead to clinical and economic burdens. Interventions capable of significantly improving medication adherence in patients with schizophrenia would be beneficial in maximizing treatment outcomes with antipsychotics. This article reviews recent literature reporting interventions designed to improve antipsychotic adherence in patients with schizophrenia. We searched the Medline, Healthstar, and PsycInfo electronic databases for articles published since 1980 on interventions to improve medication adherence in schizophrenia. Twenty-one studies met our selection criteria. In this review, educational, behavioral, affective, or a combination of these approaches to improve adherence were exammed. A total of 23 interventions were tested, as 2 studies investigated more than 1 intervention. While study design and adherence measures varied across the trials reviewed, medication adherence was noted to moderately improve with 15 of the 23 interventions tested. Interventions of a purely educational nature were the least successful at improving antipsychotic adherence. The greatest improvement in adherence was seen with interventions employing combinations of educational, behavioral, and affective strategies with which improvements in adherence were noted in 8 out of 12 studies, with additional secondary gains such as: reduced relapse, decreased hospitalization, decreased psychopathology, improved social function, gains in medication knowledge, and improved insight into the need for treatment. Longer interventions and an alliance with therapists also appeared important for successful outcomes. The continuing development and study of successful interventions to improve medication adherence are necessary to maximize the usefulness of pharmacologic treatment of schizophrenia.
Infinity Algebras, Cohomology and Cyclic Cohomology, and Infinitesimal Deformations

An A-infinity algebra is given by a codifferential on the tensor coalgebra of a (graded) vector space. An associative algebra is a special case of an A-infinity algebra, determined by a quadratic codifferential. The notions of Hochschild and cyclic cohomology generalize from associative to A-infinity algebras, and classify the infinitesimal deformations of the algebra, and those deformations preserving an invariant inner product, respectively. Similarly, an L-infinity algebra is given by a codifferential on the exterior coalgebra of a vector space, with Lie algebras being special cases given by quadratic codifferentials. There are natural definitions of cohomology and cyclic cohomology, generalizing the usual Lie algebra cohomology and cyclic cohomology, which classify deformations of the algebra and those which preserve an invariant inner product. This article explores the definitions of these infinity algebras, their cohomology and cyclic cohomology, and the relation to their infinitesimal deformations.
Pitx2c and Nkx2-5 Are Required for the Formation and Identity of the Pulmonary Myocardium

The pulmonary vein is sleeved by myocardium, which is a major source of atrial fibrillation and is involved in congenital sinus venosus defects. Little is known about the cellular origin and mechanism of formation of the pulmonary myocardium. We observed a biphasic process of pulmonary myocardium formation in mice. Firstly, a myocardial cell population forms de novo at the connection of the pulmonary vein and the atrium. Genetic labeling revealed that atrial cells do not contribute to this population, indicating it forms by differentiation of pulmonary mesenchymal cells. Secondly, these pulmonary myocardial cells initiate a phase of rapid proliferation and form the pulmonary myocardial sleeve. Pitx2c-deficient mice do not develop a pulmonary myocardial sleeve because they fail to form the initial pulmonary myocardial cells. Genetic-labeling analyses demonstrated that whereas the systemic venous return derives from Nkx2-5–negative precursors, the pulmonary myocardium derives from Nkx2-5–expressing precursors, indicating a distinct origin of the 2 venous systems. Nkx2-5 and its target gap-junction gene Cx40 are expressed in the atria and in the pulmonary myocardium but not in the systemic venous return, which expresses the essential pacemaker channel Hcn4. When Nkx2-5 protein level was lowered in a hypomorphic model, the pulmonary myocardium switched to a Cx40-negative, Hcn4-positive phenotype resembling that of the systemic venous return. In conclusion, our data suggest a cellular mechanism for pulmonary myocardium formation and highlight the key roles played by Pitx2c and Nkx2-5 in its formation and identity.
Is there a general structure for grammars?

Summary form only given. Linguists have proposed dozens of formalisms for grammars and now vision is weighing in with its versions based on its needs. Ulf Grenander has proposed general pattern theory, and has used grammar-like graphical parses of "thoughts" in the style of AI. One wants a natural, simple formalism treating all these cases. I want to pose this as a central problem in modeling intelligence. Pattern theory started in the 70's with the ideas of Ulf Grenander and his school at Brown. The aim is to analyze from a statistical point of view the patterns in all "signals" generated by the world, whether they be images, sounds, written text, DNA or protein strings, spike trains in neurons, time series of prices or weather, etc. Pattern theory proposes that the types of patterns-and the hidden variables needed to describe these patterns - found in one class of signals will often be found in the others and that their characteristic variability will be similar. The underlying idea is to find classes of stochastic models which can capture all the patterns that we see in nature, so that random samples from these models have the same "look and feel" as the samples from the world itself. Then the detection of patterns in noisy and ambiguous samples can be achieved by the use of Bayes' rule, a method that can be described as "analysis by synthesis".
Retos y riesgos del uso de Internet por parte de los menores. ¿Cómo empoderarlos?

El objetivo de este articulo es reflexionar criticamente, a partir de una seleccion de ultimos informes, investigaciones, publicaciones y otras fuentes, sobre las orientaciones de como «empoderar» a los y las menores frente a los riesgos on-line actuales. Entre los diferentes riesgos quisieramos destacar los que mas violencia emocional producen; las situaciones de «grooming» o ciberacoso, cada vez mas visibles y urgentes de prevenir conjuntamente. El uso de Internet y la facilidad de visibilizar cualquier informacion o situacion ha permitido romper el tabu social respecto a estos riesgos. Datos como el que el 44% de menores en Espana se habia sentido acosado sexualmente en Internet en alguna ocasion en el 2002, o el que el 20% de ninos en Estados Unidos sufria ciberacoso, segun una encuesta realizada a 4.400 estudiantes en el 2010, nos indican la gravedad de la problematica. Por ello, tal y como se recoge en el Curriculum MIL de la UNESCO para profesores (Media and Information Literacy), es necesario trabajar el uso responsable de Internet por parte de los y las menores, para empoderarlos evitando que puedan convertirse en futuras victimas o acosadores. A partir de los riesgos reales que pueden padecer, asi como las respuestas cientificas y sociales que se han dado al respecto, elaboraremos una serie de recomendaciones a tener en cuenta en el diseno de actividades educativas enfocadas a la capacitacion critica de los y las menores en cuanto su uso de Internet.
The Strategic Impact of Inter-organizational Information Systems – A Dynamic Capabilities Analysis

This research applies the dynamic capability perspective to examine the strategic impact of inter-organizational information systems (IOIS). In applying this perspective we argue that the value of IOIS resides in effective IOIS implementation and utilization in pursuit of superior organizational performance. This research identifies and empirically tests the impacts of information technology competence, business process reengineering, inter-organizational collaboration, and inter-organizational knowledge synergy on organizational performances. The quantitative analysis shows that information technology competence and business process reengineering are important antecedents driving the inter-organizational collaboration and knowledge synergy. Furthermore, business process reengineering, inter-organizational collaboration, and inter-organizational knowledge synergy influence organizational performance positively.
Schulklima und politische Sozialisation. Hat das perzipierte soziale Klima einen nachhaltigen Einfluss auf die Entwicklung von politischem Interesse und Toleranz

Auf der Grundlage langsschnittlicher Daten der LifE-Studie mit einer Spanne von rund 20 Jahren (1981 bis 2002) werden mogliche Einflusse des von Schulerinnen und Schulern wahrgenommenen sozialen Schulklimas auf die Entwicklung von politischem Interesse und von Toleranz gegenuber Auslandern als Indikatoren politischer Sozialisation untersucht. Bezogen auf die Entwicklung toleranter Haltungen zeigten sich auch unter Kontrolle relevanter Hintergrundvariablen signifikante Wirkungen kurz- und langfristiger Art. Deren geringe Effektstarken und die nicht statistisch absicherbaren Effekte auf das Politikinteresse relativieren allerdings uberhohte Erwartungen hinsichtlich der Bedeutung schulklimatischer Einflusse fur Prozesse der politischen Sozialisation. (DIPF/Orig.) Drawing on longitudinal data of the German LifE-Study spanning more than two decades (1981 to 2002) this analysis investigates the effects of student-perceived school climate on interest in politics and acceptance of minorities as indicators of political socialization. With respect to acceptance of minorities short- and long-term effects were significant. However, the small effect sizes and the non-effects on the interest in politics do not support overly optimistic expectations regarding the importance of the school climate for the political socialization process.

Wireless Power Transfer in Massive MIMO-Aided HetNets With User Association

This paper explores the potential of wireless power transfer (WPT) in massive multiple-input multiple-output (MIMO)-aided heterogeneous networks (HetNets), where massive MIMO is applied in the macrocells, and users aim to harvest as much energy as possible and reduce the uplink path loss for enhancing their information transfer. By addressing the impact of massive MIMO on the user association, we compare and analyze user association schemes: 1) downlink received signal power (DRSP)-based approach for maximizing the harvested energy and 2) uplink received signal power (URSP)-based approach for minimizing the uplink path loss. We adopt the linear maximal-ratio transmission beamforming for massive MIMO power transfer to recharge users. By deriving new statistical properties, we obtain the exact and asymptotic expressions for the average harvested energy. Then, we derive the average uplink achievable rate under the harvested energy constraint. Numerical results demonstrate that the use of massive MIMO antennas can improve both the users' harvested energy and uplink achievable rate in the HetNets; however, it has negligible effect on the ambient RF energy harvesting. Serving more users in the massive MIMO macrocells will deteriorate the uplink information transfer because of less harvested energy and more uplink interference. Moreover, although DRSP-based user association harvests more energy to provide larger uplink transmit power than the URSP-based one in the massive MIMO HetNets, URSP-based user association could achieve better performance in the uplink information transmission.
