Etude de la variabilité des technologies PCM et OxRAM pour leur utilisation en tant que synapses dans les systèmes neuromorphiques

Le cerveau humain est compose d’un grand nombre de reseaux neuraux interconnectes, dont les neurones et les synapses en sont les briques constitutives. Caracterise par une faible consommation de puissance, de quelques Watts seulement, le cerveau humain est capable d’accomplir des tâches qui sont inaccessibles aux systemes de calcul actuels, bases sur une architecture de type Von Neumann. La conception de systemes neuromorphiques vise a realiser une nouvelle generation de systemes de calcul qui ne soit pas de type Von Neumann. L’utilisation de memoire non-volatile innovantes en tant que synapses artificielles, pour application aux systemes neuromorphiques, est donc etudiee dans cette these. Deux types de technologies de memoires sont examines : les memoires a changement de phase (Phase-Change Memory, PCM) et les memoires resistives a base d’oxyde (Oxide-based resistive Random Access Memory, OxRAM). L’utilisation des dispositifs PCM en tant que synapses de type binaire et probabiliste est etudiee pour l’extraction de motifs visuels complexes, en evaluant l’impact des conditions de programmation sur la consommation de puissance au niveau du systeme. Une nouvelle strategie de programmation, qui permet de reduire l’impact du probleme de la derive de la resistance des dispositifs PCM est ensuite proposee. Il est demontre qu’en utilisant des dispositifs de tailles reduites, il est possible de diminuer la consommation energetique du systeme. La variabilite des dispositifs OxRAM est ensuite evaluee experimentalement par caracterisation electrique, en utilisant des methodes statistiques, a la fois sur des dispositifs isoles et dans une matrice complete de memoire. Un modele qui permets de reproduire la variabilite depuis le niveau faiblement resistif jusqu’au niveau hautement resistif est ainsi developpe. Une architecture de reseau de neurones de type convolutionnel est ensuite proposee sur la base de ces travaux experimentaux. La tolerance du circuit neuromorphique a la variabilite des OxRAM est enfin demontree grâce a des tâches de reconnaissance de motifs visuels complexes, comme par exemple des caracteres manuscrits ou des panneaux de signalisations routieres.

A New Description of Arterial Function: The Compliance-Pressure Loop

Hypertension and atherosclerosis are associated with reduced arterial compliance, which is the principal component that reflects the dynamic behavior of the arterial system. Hence, change in arterial compliance has been used as a compass of arterial wall prop erties, as well as an effective parameter for assessing therapeutic treatment efficacy. The arterial compliance-blood pressure loop concept is introduced here for assessment of arterial function. Aortic pressure and flow were measured in experimental dogs during normal and acute hypertension. The compliance-pressure loops were constructed from pulsatile blood pressure waveforms and the corresponding compliances. The features of the loop are that, for any given heart beat, arterial compliance is seen to be maximal in early systole to facilitate ventricular ejection, compliance decreasing during the re mainder of systole owing to increased blood pressure and reduced aortic flow, compli ance in diastole increasing as pressure declines. The arteries are stiffer with reduced compliance in hypertension. Thus, the compliance-pressure loop can provide an effective characterization of the dynamic behavior of the arterial system in terms of pressure-flow relation and blood vessel properties.
Risk-Sensitive Control for the Multiclass Many-Server Queues in the Moderate Deviation Regime

A G/M/N queue is considered in the moderate deviation heavy traffic regime. The rate function for the customers-in-system process is obtained for the single class model. A risk-sensitive type control problem is considered for multiclass G/M/N model under the moderate deviation scaling and shown that the optimal control problem is related to a differential game problem.
A Taxonomy of Digital Service Design Techniques

In a digital world, service designers need to apply design techniques to meet increasing user expectations. While there are many design techniques out there, the current taxonomies of design techniques provide little guidance for designers when it comes to selecting appropriate design techniques during the design process. Hence, a well-structured taxonomy is needed. This research-in-process seeks to apply a taxonomy development method to classify design techniques and to identify important dimensions in order to provide an overview of digital service design techniques. Our preliminary results present a taxonomy with five dimensions, each of which includes mutually exclusive and collectively exhaustive characteristics. In future research, we plan to evaluate the usefulness of our taxonomy and compare our taxonomy with those that are currently available. Furthermore, we expect to look into the potential interrelations among the dimensions and build a model that explains and predicts the appropriate techniques for a given situation.
Optimization design of grading ring and electrical field analysis of 800 kV UHVDC Wall wall bushing

This paper has analyzed the reason for the flashover of a typical 800 kV converting transformer bushing. The finite element method is applied to calculate the electric field and potential distribution along HV bushing as well as optimize the design of grading rings for the 800 kV UHVDC bushing. The three-dimensional (3D) model of 800kV bushing with valve hall configuration is established using ANSYS software. According to the calculation of electric field and potential distribution along the bushing without any grading ring, the joint of flange and shed and sheath has higher field intensity, and the electric field is rather unevenly distributed. Afterwards, this paper presents a method of adding a grading ring to the flange side in order to reduce the field intensity around the surface of shed & sheath. This method also optimizes the location and the configuration parameters of the grading ring, with an aim to limit the maximal electric field intensity around the metal fitting and the grading ring and obtain the optimal design of grading ring. Finally, it is verified by the 3D model that the maximal field intensity around the surface of flange, shed and sheath, and the grading ring is controlled within acceptable range, and the optimized design can be applied to the ±800 kV UHVDC power station project to reduce the occurrence probability of flashover of UHVDC bushing.
R&D intensity and financial performance

This study examines impacts of research and development (R&D) expenditure on the financial performance of Japanese manufacturing industries. For the purpose, we apply a discriminant analysis (DA) to group classification between non-default and default firms. The DA estimates a discriminant function using probit and logit models. The financial performance of a firm is evaluated by the estimated discriminant function. The relationship between the financial performance and R&D intensity is investigated using the function, as well. The results identify that R&D expenditure makes a positive impact on the financial performance of Japanese machinery industry, but it yields a negative impact on Japanese electrical equipment industry.
Visual responses of neurones in the second visual area of flying foxes (Pteropus poliocephalus) after lesions of striate cortex

1 The first (V1) and second (V2) cortical visual areas exist in all mammals. However, the functional relationship between these areas varies between species. While in monkeys the responses of V2 cells depend on inputs from V1, in all non‐primates studied so far V2 cells largely retain responsiveness to photic stimuli after destruction of V1. 2 We studied the visual responsiveness of neurones in V2 of flying foxes after total or partial lesions of the primary visual cortex (V1). The main finding was that visual responses can be evoked in the region of V2 corresponding, in visuotopic co‐ordinates, to the lesioned portion of V1 (‘lesion projection zone’; LPZ). 3 The visuotopic organization of V2 was not altered by V1 lesions. 4 The proportion of neurones with strong visual responses was significantly lower within the LPZs (31.5 %) than outside these zones, or in non‐lesioned control hemispheres (> 70 %). LPZ cells showed weak direction and orientation bias, and responded consistently only at low spatial and temporal frequencies. 5 The data demonstrate that the functional relationship between V1 and V2 of flying foxes resembles that observed in non‐primate mammals. This observation contrasts with the ‘primate‐like’ characteristics of the flying fox visual system reported by previous studies.
Heparin-Mimicking Sulfonic Acid Polymers as Multitarget Inhibitors of Human Immunodeficiency Virus Type 1 Tat and gp120 Proteins

ABSTRACT Human immunodeficiency virus (HIV) Tat and gp120 intriguingly share the feature of being basic peptides that, once released by HIV+ cells, bind to polyanionic heparan sulfate proteoglycans (HSPGs) on target uninfected cells, contributing to the onset of AIDS-associated pathologies. To identify multitarget anti-HIV prodrugs, we investigated the gp120 and Tat antagonist potentials of a series of polyanionic synthetic sulfonic acid polymers (SSAPs). Surface plasmon resonance revealed that SSAPs inhibit with a competitive mechanism of action the binding of Tat and gp120 to surface-immobilized heparin, an experimental condition that resembles binding to cellular HSPGs. Accordingly, SSAPs inhibited HSPG-dependent cell internalization and the transactivating activity of Tat. Little is known about the binding of free gp120 to target cells. Here, we identified two classes of gp120 receptors expressed on endothelial cells, one of which was consistent with an HSPG-binding, low-affinity/high-capacity receptor that is inhibited by free heparin. SSAPs inhibited the binding of free gp120 to endothelial cells, as well as its capacity to induce apoptosis in the same cells. In all the assays, poly(4-styrenesulfonic acid) (PSS) proved to be the most potent antagonist of Tat and gp120. Accordingly, PSS bound both proteins with high affinity. In conclusion, SSAPs represent an interesting class of compounds that bind both gp120 and Tat and inhibit their HSPG-dependent cell surface binding and pathological effects. As these activities contribute to both AIDS progression and associated pathologies, SSAPs can be considered prototypic molecules for the development of multitarget drugs for the treatment of HIV infection and AIDS-associated pathologies.
Optimized tools for multicolor stochastic labeling reveal diverse stereotyped cell arrangements in the fly visual system

Significance Nervous systems contain vast numbers of neurons with diverse shapes and complex spatial relationships. We describe new genetic tools for the efficient visualization by light microscopy of individual neurons and their relative positions in Drosophila. The application of these methods to the visual system revealed an unexpected diversity of cell-type–specific arrangements of neuronal processes within a single brain region. This wide range of stereotyped cell arrangements provides distinct circuit elements for processing visual information and implies the existence of a surprisingly large number of genetic programs that produce these arrangements during development. We describe the development and application of methods for high-throughput neuroanatomy in Drosophila using light microscopy. These tools enable efficient multicolor stochastic labeling of neurons at both low and high densities. Expression of multiple membrane-targeted and distinct epitope-tagged proteins is controlled both by a transcriptional driver and by stochastic, recombinase-mediated excision of transcription-terminating cassettes. This MultiColor FlpOut (MCFO) approach can be used to reveal cell shapes and relative cell positions and to track the progeny of precursor cells through development. Using two different recombinases, the number of cells labeled and the number of color combinations observed in those cells can be controlled separately. We demonstrate the utility of MCFO in a detailed study of diversity and variability of Distal medulla (Dm) neurons, multicolumnar local interneurons in the adult visual system. Similar to many brain regions, the medulla has a repetitive columnar structure that supports parallel information processing together with orthogonal layers of cell processes that enable communication between columns. We find that, within a medulla layer, processes of the cells of a given Dm neuron type form distinct patterns that reflect both the morphology of individual cells and the relative positions of their arbors. These stereotyped cell arrangements differ between cell types and can even differ for the processes of the same cell type in different medulla layers. This unexpected diversity of coverage patterns provides multiple independent ways of integrating visual information across the retinotopic columns and implies the existence of multiple developmental mechanisms that generate these distinct patterns.
Study on siting and sizing of battery-switch station

According to strong proponent of energy conservation and emission reduction, the development of new energy vehicles has been upgraded to the national strategic level in "Twelfth Five-Year Plan" period, and it becomes the main theme of Chinese automobile industry. And the planning of electric vehicle battery-switch station (BBS) has a great impact on the popularisation of electric vehicle and the security of power system. For reasonably planning of the location and sizing of the BBS, an optimization planning cost model and a new demand model of battery-switch station are proposed. This demand model is based on analysis of customers' characteristics. And in the optimization cost model, the objective function includes such variables as network loss cost, building cost and running cost of a particular battery-switch station, electrovalence and so on. Its constraints include the acceptable load power of the power system, the demand of electric vehicles, and the limitation of service territory of the BBS and so on. Finally, a practical example is carried out to demonstrate the performance of the demand model and the planning method.
Successful long‐term erythrocytapheresis therapy in a patient with symptomatic sickle‐cell disease using an arterio‐venous fistula

Summary The use of long‐term automated erythrocytapheresis via an arterio‐venous fistula for the prevention of recurrent ischaemic stroke in a child with sickle‐cell disease (SCD) has not been described previously. We report the successful use of this technique in a 13‐year‐old boy. A procedure was performed every 36 ± 6 days, transfusing six units of donor packed red blood cells (RBCs) and discarding 1318 ± 174 mL of exchanged erythrocytes (Hct 60%). After transfusion of 85 units over 17 months, there is no evidence for iron‐overload, red cell alloimmunization, transfusion‐transmitted infections, or other complications. Until now, no cerebrovascular ischaemia has been observed.
IoT infrastructure to increase access to non-ADA buildings

As IT technology develops rapidly, society is changing to where all things are connected together beyond the computing and mobile era. As a result, the global smart building market is steadily growing. However, these IoT technologies are somewhat currently limited to newer buildings, and it is a reality that they pay mainly through service companies. In order to popularize IoT technology, it should be convenient to use and aocesable to the general public, especially those with physical or mental challenges, who can gain advantage through newer technologies. In this paper, we propose a method to integrate IoT technology into buildings using simple, inexpensive and accessible devices and open source software to create technology for adapting non-ADA compliant buildings and structures. Based on technology such as the Raspberry Pi, Amazon Web Services and the OpenCV Python Library can be used to control various actions in the building. The desire is this method will inspire IoT development to be used in a variety of ways that create greater accessibility in physical, economic and technological dimensions. All of the technology developed in this work is controlled by mobile, wearable components that can be customized depending on the specific physical challenge of the user.
Identifying and Analyzing the Prevalent Regions of a Co-Location Pattern Using Polygons Clustering Approach

Given a co-location pattern consisting of spatial features, the prevalent region mining process identifies local areas in which these features are co-located with a high probability. Many approaches have been proposed for co-location mining due to its key role in public safety, social-economic development and environmental management. However, traditionally, most of the solutions focus on itemsets mining and results outputting in a textual format, which fail to adequately treat all the spatial nature of the underlying entities and processes. In this paper, we propose a new co-location analysis approach to find the prevalent regions of a pattern. The approach combines kernel density estimation and polygons clustering techniques to specifically consider the correlation, heterogeneity and contextual information existing within complex spatial interactions. A kernel density estimation surface is created for each feature and subsequently the generated multiple surfaces are combined into a final surface with cell attribute representing the pattern prevalence measure value. Polygons consisting of cells are then extracted according to the predefined threshold. Through adding appended environmental data to the polygons, an outcome of similar groups is achieved using polygons clustering approach. The effectiveness of our approach is evaluated using Points-of-Interest datasets in Shenzhen, China.

Cooperative differential game for model energy-bandwidth efficiency tradeoff in the Internet of Things

Internet of Things (IoT) refers to an infrastructure which enables the forms of communication and collaboration between people and things, and between things themselves. In order to improve its performance, we present a tradeoff between bandwidth and energy consumption in the IoT in this paper. A service providing model is built to find the relationship between bandwidth and energy consumption using a cooperative differential game model. The game solution is gotten in the condition of grand coalition, feedback Nash equilibrium and intermediate coalitions and an allocation policy is obtain by Shapley theory. The results are shown as follows. Firstly, the performance of IoT decreases with the increasing of bandwidth cost or with the decreasing of energy cost; secondly, all the nodes in the IoT composing a grand coalition can save bandwidth and energy consumption; thirdly, when the factors of bandwidth cost and energy cost are equal, the obtained number of provided services is an optimised value which is the trade-off between energy and bandwidth consumption.
