Scalable flexible chip-level parylene package for high lead count retinal prostheses

The authors presented an innovative technology for the fabrication of a biocompatible parylene-based high lead count retinal prosthesis in which a prefabricated stand-alone application-specific integrated circuit (ASIC) is placed directly into the fabrication process of the other system components. The package is fabricated in such a way that the ASIC-to-electrode interconnects are patterned using standard photolithography. The density of interconnects is fully scalable to the limits of lithography. This packaging scheme also enables the simultaneous integration and interconnection of discrete components such as chip capacitors with the rest of the system. Electrical test results verify the efficacy of this cost-effective and high-yield packaging scheme, and pave the way for a monolithic implantable parylene-based intraocular system.

The Form Factor Program: a Review and New Results - the Nested SU(N) Off-Shell Bethe Ansatz ?

The purpose of the "bootstrap program" for integrable quantum field theories in 1+1 dimensions is to construct explicitly a model in terms of its Wightman functions. In this article, this program is mainly illustrated in terms of the sinh-Gordon model and the SU(N) Gross-Neveu model. The nested off-shell Bethe ansatz for an SU(N) factorizing S-matrix is constructed. We review some previous results on sinh-Gordon form factors and the quantum operator field equation. The problem of how to sum over intermediate states is considered in the short distance limit of the two point Wightman function for the sinh-Gordon model.
Lightweight IPTV transport option for wireless broadband access

As intelligent content management reduces the latency between IPTV video serving office and mobile device, it becomes feasible to introduce a limited form of negative acknowledgments. Scalable video lends itself to selective acknowledgment, as does selection by video picture type. The defining characteristic of mobile video transport schemes is the response to handover. In this paper, it is demonstrated that the scalable selective negative acknowledgment transport scheme proposed decreases throughput but can retain acceptable video quality during vertical handover from an outdoors WiMAX system and an indoors IEEE 802.11 system.
Suboptimal solutions using integer approximation techniques for scheduling divisible loads on distributed bus networks

The problem of optimal divisible load distribution in distributed bus networks employing a heterogeneous cluster of processors is addressed. The objective is to minimize the total processing time of the entire load subject to the communication and computation delays. In the mathematical model we adopt, both the granularity of the load fractions and all the associated overheads (also referred to as start-up costs) in the process of communication and computation, are considered explicitly in the problem formulation. We introduce a directed flow graph model for representing the load distribution process. This representation is novel to this literature. With this model, we first derive a closed-form solution for an optimal processing time. We propose an integer approximation algorithm and derive ultimate performance bounds for the class of homogeneous networks. We then extend the problem to a special class of application problems in which the data partitioning is restricted to a finite number of partitions. For this case, we present a recursive procedure to obtain optimal processing time. We then present two different integer approximation algorithms-PIA and IIA that could generate integer load fractions and yield suboptimal solutions. The choice of these algorithms are also analyzed. All the results are extended to a class of homogeneous networks to obtain ultimate performance bounds. Several illustrative examples are provided for ease of explanation.
Phospholipid and cholesterol content of epididymal and ejaculated ram spermatozoa and seminal plasma in relation to cold shock.

The concentration of total phospholipid, phosphatidylcholine, phosphatidylethanolamine, and choline plasmalogen in spermatozoa from the caput epididymis of the ram was higher than in spermatozoa from the cauda. The phospholipid composition of spermatozoa from the latter region of the epididymis more closely resembled ejaculated spermatozoa.
Future changes in climate, ocean circulation, ecosystems, and biogeochemical cycling simulated for a business‐as‐usual CO2 emission scenario until year 4000 AD

A new model of global climate, ocean circulation, ecosystems, and biogeochemical cycling, including a fully coupled carbon cycle, is presented and evaluated. The model is consistent with multiple observational data sets from the past 50 years as well as with the observed warming of global surface air and sea temperatures during the last 150 years. It is applied to a simulation of the coming two millennia following a business‐as‐usual scenario of anthropogenic CO2 emissions (SRES A2 until year 2100 and subsequent linear decrease to zero until year 2300, corresponding to a total release of 5100 GtC). Atmospheric CO2 increases to a peak of more than 2000 ppmv near year 2300 (that is an airborne fraction of 72% of the emissions) followed by a gradual decline to ∼1700 ppmv at year 4000 (airborne fraction of 56%). Forty‐four percent of the additional atmospheric CO2 at year 4000 is due to positive carbon cycle–climate feedbacks. Global surface air warms by ∼10°C, sea ice melts back to 10% of its current area, and the circulation of the abyssal ocean collapses. Subsurface oxygen concentrations decrease, tripling the volume of suboxic water and quadrupling the global water column denitrification. We estimate 60 ppb increase in atmospheric N2O concentrations owing to doubling of its oceanic production, leading to a weak positive feedback and contributing about 0.24°C warming at year 4000. Global ocean primary production almost doubles by year 4000. Planktonic biomass increases at high latitudes and in the subtropics whereas it decreases at midlatitudes and in the tropics. In our model, which does not account for possible direct impacts of acidification on ocean biology, production of calcium carbonate in the surface ocean doubles, further increasing surface ocean and atmospheric pCO2. This represents a new positive feedback mechanism and leads to a strengthening of the positive interaction between climate change and the carbon cycle on a multicentennial to millennial timescale. Changes in ocean biology become important for the ocean carbon uptake after year 2600, and at year 4000 they account for 320 ppmv or 22% of the atmospheric CO2 increase since the preindustrial era.
Stroke surfaces: temporally coherent artistic animations from video

The contribution of this paper is a novel framework for synthesizing nonphotorealistic animations from real video sequences. We demonstrate that, through automated mid-level analysis of the video sequence as a spatiotemporal volume - a block of frames with time as the third dimension - we are able to generate animations in a wide variety of artistic styles, exhibiting a uniquely high degree of temporal coherence. In addition to rotoscoping, matting, and novel temporal effects unique to our method, we demonstrate the extension of static nonphotorealistic rendering (NPR) styles to video, including painterly, sketchy, and cartoon shading. We demonstrate how this novel coherent shading framework may be combined with our earlier motion emphasis work to produce a comprehensive "video paintbox" capable of rendering complete cartoon-styled animations from video clips.
On the onset of galactic winds in quiescent star forming galaxies

Context. The hierarchical model of galaxy formation, despite its many successes, still overpredicts the baryons fraction locked in galaxies as a condensed phase. The efficiency of supernovae feedback, proposed a long time ago as a possible solution for this so-called “overcooling” problem, is still under debate, mainly because modelling supernovae explosions within a turbulent interstellar medium, while capturing realistic large scale flows around the galaxy is a very demanding task. Aims. Our goal is to study the effect of supernovae feedback on a disc galaxy, taking into account the impact of infalling gas on both the star formation history and the corresponding outflow structure, the apparition of a supernovae-driven wind being highly sensitive to the halo mass, the galaxy spin and the star formation efficiency. Methods. We model our galaxies as cooling and collapsing NFW spheres. The dark matter component is modelled as a static external potential, while the baryon component is described by the Euler equations using the AMR code RAMSES. Metal-dependent cooling and supernovae-heating are also implemented using state-of-the-art recipes coming from cosmological simulations. We allow for three parameters to vary: the halo circular velocity, the spin parameter and the star formation efficiency. Results. We found that the ram pressure of infalling material is the key factor limiting the apparition of galactic winds. We obtain a very low feedback efficiency, with supernovae to wind energy conversion factor around one percent, so that only low circular velocity galaxies give rise to strong winds. For massive galaxies, we obtain a galactic fountain, for which we discuss the observational properties. Conclusions. We conclude that for quiescent isolated galaxies, galactic winds appear only in very low mass systems. Although this can quite efficiently enrich the IGM with metals, they do not carry away enough cold material to solve the overcooling problem.
Investigation of the elementary mechanisms controlling dislocation/twin boundary interactions in fcc metals and alloys : from conventional to advanced TEM characterization

The elementary mechanisms controlling the interactions between lattice gliding dislocations and twin boundaries were carefully analyzed using conventional and advanced transmission electron microscopy techniques in both bulk coarsegrained Fe-Mn-C TWIP steels with deformation twins and nanocrystalline Palladium thin films with nanoscale growth twins. The results reveal that the individual dislocation/TB reactions depend mainly on the stacking fault energy of the material as well as the nature of the incoming dislocations nucleated during the plastic deformation of the material. It is also demonstrated that such investigation requires dedicated and specific microscopic techniques depending on the microstructure and the intrinsic properties of the crystallographic defects of the materials.
Hormones and immunity in cancer: are thyroid hormones endocrine players in the microglia/glioma cross-talk?

Accumulating evidence indicates that the endocrine and immune systems engage in complex cross-talks in which a prominent role is played by thyroid hormones (THs). The increase of resident vs. monocyte recruited macrophages was shown to be an important effector of the TH 3,3′,5′-Triiodo-L-thyronine (T3)-induced protection against inflammation and a key role of T3 in inhibiting the differentiation of peripheral monocytes into macrophages was observed. Herein, we report on the role of T3 as a modulator of microglia, the specialized macrophages of the central nervous system (CNS). Mounting evidence supports a role of microglia and macrophages in the growth and invasion of malignant glioma. In this respect, we unveil the putative involvement of T3 in the microglia/glioma cell communication. Since THs are known to cross the blood-brain barrier, we suggest that T3 not only exerts a direct modulation of brain cancer cell itself but also indirectly promotes glioma growth through a modulation of microglia. Our observations expand available information on the role of TH system in glioma and its microenvironment and highlight the endocrine modulation of microglia as an important target for future therapeutic development of glioma treatments.
An observer based distributed controller for formation flying of satellites

In this paper, a novel nonlinear observer and controller framework is suggested for achieving formation control of a cluster of satellites. Exploiting the skew symmetry in the satellite dynamics, a novel nonlinear observer which has roots in the super-twist sliding mode observer is proposed. Estimation of the entire states and unknown bounded disturbances (and also faulty, corrupted leader control signals) in finite time is demonstrated using an elegant Lyapunov analysis. The proposed distributed controller is based on the state estimates and the relative position output information which depends on the underlying communication topology. The novelty in the synthesis of the controller is mainly in the treatment of the underlying graph topology, the interaction amongst the satellites in terms of relative sensing, and the synthesis of the controller gains using a simple polytopic representation that depends on the graph Laplacian eigenvalues. A simulation example is provided to demonstrate the efficacy of the proposed approach.
THE FOUNDATION OF ENTREPRENEURIAL INTENTION

Individual intentions influence human behaviors and, as a consequence, organizational outcomes. Therefore, the ability to understand and to predict intentions becomes a central issue in the managerial literature. In this contribution we study the formulation of entrepreneurial intentions. Drawing on a widely used intentional paradigm, the theory of planned behavior (Ajzen, 1991), we model the influence of individual characteristics and contextual variables on the intention formation process. Relying on a sample of 200 entrepreneurs, founders of 133 new-technology-based firms, we test a theoretical model of the micro-foundation of entrepreneurial intention. Our results show that entrepreneurial intention is influenced by psychological characteristics, by individual skills and by environmental influences. Managerial implications related to the creation of the conditions fostering entrepreneurial intentions within companies are discussed.
Exploiting inherent regularity in control of multilegged robot locomotion by evolving neural fields

The control of multilegged robots is challenging because of the large number of sensors and actuators involved. However, the regularity inherent to gait control can be taken into account to design controllers for multilegged robots. In this paper, we show that NEATfields, a method designed for the evolution of large neural networks, can exploit this regularity to evolve significantly better gaits than those evolved by the standard NEAT method. We also show how evolved networks can control a robot with a ball-like morphology to move on a rough terrain. The success in evolving large neural networks suggests that the NEATfields method is a promising tool for studying complex behaviors in robotics and artificial life.
Dipole models for the EEG and MEG

The current dipole is a widely used source model in forward and inverse electroencephalography and magnetoencephalography applications. Analytic solutions to the governing field equations have been developed for several approximations of the human head using ideal dipoles as the source model. Numeric approaches such as the finite-element and finite-difference methods have become popular because they allow the use of anatomically realistic head models and the increased computational power that they require has become readily available. Although numeric methods can represent more realistic domains, the sources in such models are an approximation of the ideal dipole. In this paper, we examine several methods for representing dipole sources in finite-element models and compare the resulting surface potentials and external magnetic field with those obtained from analytic solutions using ideal dipoles.
Myasthenia Gravis Susceptible to Experimental Autoimmune Receptor Deficiency Are Less g Mice with IFN-van

IFN- g can either adversely or beneﬁcially affect certain experimental autoimmune diseases. To study the role of IFN- g in the autoantibody-mediated experimental autoimmune myasthenia gravis (EAMG), an animal model of myasthenia gravis in humans, IFN- g R-deﬁcient (IFN- g R 2 / 2 ) mutant C57BL/6 mice and congenic wild-type mice were immunized with Torpedo acetylcholine receptor (AChR) plus CFA. IFN- g R 2 / 2 mice exhibited signiﬁcantly lower incidence and severity of muscle weakness, lower anti-AChR IgG Ab levels, and lower Ab afﬁnity to AChR compared with wild-type mice. Passive transfer of serum from IFN- g R 2 / 2 mice induced less muscular weakness compared with serum from wild-type mice. In contrast, numbers of lymph node cells secreting IFN- g and of those expressing IFN- g mRNA were strongly augmented in the IFN- g R 2 / 2 mice, reﬂecting a failure of negative feedback circuits. Cytokine studies by in situ hybridization revealed lower levels of lymphoid cells expressing AChR-reactive IL-1 b and TNF- a mRNA in AChR 1 CFA-immunized IFN- g R 2 / 2 mice compared with wild-type mice. No differences were found for AChR-reactive cells expressing IL-4, IL-10, or TGF- b mRNA. These results indicate that IFN- g promotes systemic humoral responses in EAMG by up-regulating the production and the afﬁnity of anti-AChR autoantibodies, thereby contributing to susceptibility to EAMG in C57BL/6-type mice. The Journal of Immunology, 1999, 162: 3775–3781.
Patterns of Single Mothers' Work and Welfare Use

Few studies have captured the variation in single mothers' work and welfare experiences and the implications for children. Using data from the Panel Study of Income Dynamics and the Child Development Study, this study examines patterns of wages, work hours, and time spent on welfare in relation to children's well-being (N = 820). Six patterns emerged and were related to differences in children's outcomes, with lower well-being among children whose mothers had left welfare for work or who stayed on welfare. Findings differed by children's age and gender among some groups. Considering how these patterns relate to children may help in the design and implementation of programs or services.
Rivermead Behavioural Memory Test

La Cour, P. & Gallagher, K. (1990). Presentation and evaluation of Rivermead Behavioural Memory Test. Nordisk Psykologi, 42, 130–141. The article presents an evaluation of the Rivermead Behavioural Memory Test, a test battery for illuminating impaired memory function. The RBMT has recently been published in Danish together with a short review of its background and contents. Results from 10 examinations where both RBMT and a traditional test battery were applied lead to a discussion regarding the tests merits and shortcomings. The test battery has shown to be of benefit where everyday memory functions are estimated.
Emotional and Adrenal Reactions to Stress in Bronchial Asthma

&NA; Urinary epinephrine (E), norepinephrine (NE) and vanylmandelic acid (VMA), plasma cortisol and free fatty acids (FFA), respiratory and cardiovascular indices, and subjectively reported emotion were measured on successive days under conditions of stress and relaxation in 6 healthy males and 6 matched young males with perennial, mild‐to‐moderate bronchial asthma in remission. They had taken no medication for at least a week and no steroids for 6 months. Asthmatics, as compared to control Ss, had significantly lower urinary E values, during both stress and control periods. Initial levels of NE and VMA excretion in urine were normal; NE levels responded to stress as expected, but did not discriminate between groups. Plasma cortisol did not differ between groups in this small sample. These findings argue against a global sympathetic nervous system or adrenal cortical defect, and are consistent with the hypothesis of a specific hypothalamicadrenal medullary defect in bronchial asthma. Respiratory indices (unlike heart rate and blood pressure) differentiated between the groups: asthmatics had lower airway conductance and respiratory rate and an opposite direction of change in these indices under stress. Psychologically, asthmatic Ss exhibited a marked field independence and, although as emotionally aroused by stressors as were controls, gave evidence of inhibition of aggressive impulses.
Learning a Coupled Linearized Method in Online Setting

Based on the alternating direction method of multipliers, in this paper, we propose, analyze, and test a coupled linearized method, which aims to minimize an unconstrained problem consisting of a loss term and a regularization term in an online setting. To solve this problem, we first transform it into an equivalent constrained minimization problem with a separable structure. Then, we split the corresponding augmented Lagrangian function and minimize the resulting subproblems distributedly with one variable by fixing another one. This method is easy to execute without calculating matrix inversion by implementing three linearized operations per iteration, and at each iteration, we can obtain a closed-form solution. In particular, our update rule contains the well-known soft-thresholding operator as a special case. Moreover, upper bound on the regret of the proposed method is analyzed. Under some mild conditions, it can achieve <inline-formula> <tex-math notation="LaTeX">$O(1/\sqrt {T})$ </tex-math></inline-formula> convergence rate for convex learning problems and <inline-formula> <tex-math notation="LaTeX">$O(({\rm {log}} {T})/ {T})$ </tex-math></inline-formula> for strongly convex learning. Numerical experiments and comparisons with several state-of-the-art methods are reported, which demonstrate the efficiency and effectiveness of our approach.
An Enhanced Reservation-Based MAC Protocol for IEEE 802.15.4 Networks

The IEEE 802.15. 4 Medium Access Control (MAC) protocol is an enabling standard for wireless sensor networks. In order to support applications requiring dedicated bandwidth or bounded delay, it provides a reservation-based scheme named Guaranteed Time Slot (GTS). However, the GTS scheme presents some drawbacks, such as inefficient bandwidth utilization and support to a maximum of only seven devices. This paper presents eLPRT (enhanced Low Power Real Time), a new reservation-based MAC protocol that introduces several performance enhancing features in comparison to the GTS scheme. This MAC protocol builds on top of LPRT (Low Power Real Time) and includes various mechanisms designed to increase data transmission reliability against channel errors, improve bandwidth utilization and increase the number of supported devices. A motion capture system based on inertial and magnetic sensors has been used to validate the protocol. The effectiveness of the performance enhancements introduced by each of the new features is demonstrated through the provision of both simulation and experimental results.
