Le SIDA : la carte animée comme rhétorique cartographique appliquée (1990)

Malgré la diffusion d’informations, l’expansion rapide de l’épidémie de SIDA demeure un fait ignoré de la plupart, aux Etats-Unis. Afin de trouver des «signaux», qui rendent la menace de cette épidémie mortelle moins «distante», une équipe de recherche interuniversitaire a produit des séquences de cartes animées pour des campagnes télévisuelles d’intervention éducative. Le travail réalisé sur ces images animées a conduit les chercheurs à s’interroger sur les problèmes de la «visualisation scientifique».
Cyclic Voltammetric Study of the Oxidation of Catechols in the Presence of Cyanide Ion (2004)

Abstract Electrochemical oxidation of catechols has been studied in the presence of cyanide ion as nucleophile in aqueous solution, by means of cyclic voltammetry and controlled‐potential coulometry. The results indicate that the participation of catechols in the Michael reaction with cyanide ion to form the corresponding o ‐dihydroxybenzonitrile. Based on an EC mechanism, the homogeneous rate constants were estimated by comparing the experimental cyclic voltammetric responses with the digital simulated results.
Noninvasive detection of intracranial vascular lesions using an electronic stethoscope (1984)

Using an electronic stethoscope, the authors have attempted noninvasive detection of intracranial aneurysms, arteriovenous malformations (AVM's), and carotid cavernous fistulas in 45 patients. A microphone of older design and a newly designed horn-coupled probe microphone were used to record the sound signals emanating from the cranium. A trigger pulse recorded by another microphone placed over the carotid area or the precordium was used to time the intracranial signals. The sound signals were converted to electrical signals, amplified, filtered, and analyzed using fast Fourier transformation to give plots of amplitude versus frequency of the signals. A spike at a certain frequency or a bruit over a band of frequencies was considered a positive finding. The records of 18 of the patients were not satisfactory for analysis, mainly due to external noise interference. Eight of 11 aneurysm patients with satisfactory recordings emitted resonant spikes, turbulent bruits, or combinations of the two. The other three records were negative. Four patients with AVM's and two with carotid cavernous fistulas exhibited broad-band bruits representing turbulent flow. Neither spikes nor bruits were demonstrable in three patients with brain tumors or in seven patients without intracranial vascular lesions. Experimental vein pouch aneurysms were also induced in two dogs. Recordings from these animals revealed resonant spikes. The limitations and scope of electronic stethoscope audiometry are discussed.

The design of DEETM: A framework for dynamic energy efficiency and temperature management (2001)

While technology is delivering increasingly sophisticated and powerful chip designs, it is also imposing alarmingly high energy requirements on the chips. One way to address this problem is to manage the energy dynamically. Unfortunately, current dynamic schemes for energy management are relatively limited. In addition, they manage energy either for energy efficiency or for temperature control, but not for both simultaneously.
Perceptual embedded image coding using wavelet transforms (2002)

We present a modified version of an embedded wavelet coding scheme, first suggested by Shapiro (see IEEE Transactions on Signal Processing, vol.41, no. 12, p.3445-3462, 1993), that improves the performance of the original algorithm in a visual subjective distortion sense. We preserve the features of the original Shapiro's embedded coder. It is possible to choose a fixed target bit rate, as the information needed to represent an image coded at some rate always contains the needed information for the same image coded at lower rates. Therefore, the decoder can cease decoding the bit stream at any point, simulating an image coded at a lower rate corresponding to the truncated bit stream. We also introduce some perceptive improvements by adopting different (more regular) filters with respect to the original QMF pyramid filters proposed by Simoncelli, Hingorani et al. (1987) and used by Shapiro. These filters are synthesized using a "wavelet approach" instead of a "subband approach", and this leads to a better control on their regularity properties, jointly with better perceptual performance.

Approximate Computing for Biometric Security Systems: A Case Study on Iris Scanning (2018)

Exploiting the error resilience of emerging data-rich applications, approximate computing promotes the introduction of small amount of inaccuracy into computing systems to achieve significant reduction in computing resources such as power, design area, runtime or energy. Successful applications for approximate computing have been demonstrated in the areas of machine learning, image processing and computer vision. In this paper we make the case for a new direction for approximate computing in the field of biometric security with a comprehensive case study of iris scanning. We devise an end-to-end flow from an input camera to the final iris encoding that produces sufficiently accurate final results despite relying on intermediate approximate computational steps. Unlike previous methods which evaluated approximate computing techniques on individual algorithms, our flow consists of a complex SW/HW pipeline of four major algorithms that eventually compute the iris encoding from input live camera feeds. In our flow, we identify overall eight approximation knobs at both the algorithmic and hardware levels to trade-off accuracy with runtime. To identify the optimal values for these knobs, we devise a novel design space exploration technique based on reinforcement learning with a recurrent neural network agent. Finally, we fully implement and test our proposed methodologies using both benchmark dataset images and live images from a camera using an FPGA-based SoC. We show that we are able to reduce the runtime of the system by 48 χ on top of an already HW accelerated design, while meeting industry-standard accuracy requirements for iris scanning systems.

Detection and Hemodynamic Significance of Cardiac Pacemaker–Induced Phrenic Nerve Stimulation (2010)

The authors investigated acoustic cardiography, the digital analysis of electrocardiogram (ECG) and heart sounds, to detect phrenic nerve stimulation (PNS) and assess its hemodynamic significance. They studied 42 patients and induced 46 instances of PNS induced through cardiac pacing at various locations in the heart. These 46 instances of PNS were either independently documented using fluoroscopy or were symptomatic. The authors collected acoustic cardiography data including the electromechanical activation time (interval from Q onset to the first heart sound [S1]) as a percentage of the RR interval (%EMAT) to assess systolic function. Acoustic cardiography provided evidence of PNS when it occurred. They also found significant %EMAT prolongation when right ventricular pacing was associated with PNS (Delta%EMAT=2.7, P=.012), but none beyond the normal range with right ventricular pacing in the absence of PNS. Documented PNS occurred in 33 episodes (60%) in patients with noticeable symptoms. Stimulation amplitudes could be found that generated asymptomatic PNS for all of the five participants explicitly tested for it. PNS can be asymptomatic. PNS due to right ventricular pacing is associated with impaired left ventricular systolic function. Acoustic cardiography is an effective method of detecting and assessing the hemodynamic significance of pacemaker-related PNS.
Precise Control of Ferrite Phase Shifters (1959)

Hysteresis and thermal drifts can prevent accurate calibration of ferrite phase shifters. To provide a precise setting of phase in response to a control signal a servo system has been developed. This system utilizes a control frequency to determine uniquely the phase shift in a ferrite element. The desired phase shift is then a function only of control frequency and line length. Performance data are given for various operating conditions of the control system.
Enhancement of miscibility between hemicellulose and lignin by addition of their copolymer, the lignin‐carbohydrate complex (1994)

Abstract The miscibility between hemicellulose and lignin from beech wood was investigated from observation of their glass transition temperature, along with the effect of addition of their copolymer, the lignin‐carbohydrate complex (LCC). The binary and ternary blend systems of hemicellulose, lignin and LCC change from immiscible to miscible by increasing the temperature. This behavior shows that this blend system has an upper critical solution temperature (UCST). The binodal temperature decreases with increasing amount of LCC added. This behavior was analyzed by the temperature and composition dependence of the Flory polymer‐polymer interaction parameter (χ 12 ). The value of χ 12 estimated from the phase diagrams indicates that χ 12 decreases with an increase in both the lignin content and the temperature.
A new SLM OFDM scheme with low complexity for PAPR reduction (2005)

The authors introduce a new selected mapping (SLM) orthogonal frequency division multiplexing (OFDM) scheme with low computational complexity. The proposed SLM scheme transforms an input symbol sequence into a set of OFDM signals by multiplying the phase sequences to the signal after a certain intermediate stage of inverse fast Fourier transform (IFFT). Then, the OFDM signal with the lowest peak-to-average power ratio (PAPR) is selected for transmission. The new SLM OFDM scheme reduces the computational complexity, while it shows almost the same performance of PAPR reduction as that of the conventional SLM OFDM scheme.

Monolithic integration of solid state thermionic coolers with semiconductor lasers (2002)

Many types of semiconductor lasers such as vertical cavity surface emitting lasers (VCSELs) or distributed feedback (DFB) lasers can generate large heat power densities on the order of kW/cm/sup 2/ over areas as small as 100 /spl mu/m/sup 2/. It is desirable in many applications to control the operating temperature in order to tune the operating characteristics such as emission wavelength or to enhance the performance such as increasing the output power. Conventionally, thermoelectric (TE) coolers are used to manage temperature, however since they are not easily integrated with semiconductor devices, the packaging can be costly. Moreover, the TE device usually determines the reliability and lifetime of a packaged laser module. An alternative to traditional TE coolers is heterostructure integrated thermionic coolers. These thin film coolers use the selective emission of hot electrons over a heterostructure barrier layer from emitter to collector resulting in an evaporative cooling of the electron gas beyond what is possible with the Peltier effect. Thermionic coolers fabricated in the InGaAsP material system have demonstrated cooling on the order of several degrees over one-to-two micron thick barriers and cooling power densities of over 100 W/cm/sub 2/. This cooling power density is approximately an order of magnitude greater than what is possible with TE coolers. The InGaAsP material system is important for long wavelength semiconductor lasers used in long haul and other high-speed optical communication systems. By using the same material system for the laser and cooler growth, monolithic integration is possible.
Microbiological and enzymatic activity of bovine whole milk treated by pulsed electric fields (2017)

Pulsed electric field ( PEF )‐treated milk (25.7 kV/cm for 34 μs after preheating to 55 °C and holding for 24 s) was microbiologically stable for 21 days at 4 °C, and similar to thermally treated milk (63 °C for 30 min or 73 °C for 15 s). Alkaline phosphatase inactivation was comparable after PEF (preheating followed by PEF ) and both thermal treatments. PEF treatment initially reduced xanthine oxidase (30%) and plasmin (7%) activities, but after 21 days of refrigerated storage these activities were similar to the initial untreated milk. During refrigerated storage of PEF (preheating followed by PEF ) and thermally treated milk, lipolytic activity increased and pH levels decreased.
Electrophoresis in Microfluidic Systems (2007)

Many chemical and biochemical analysis methods involve performing a sequence of processes that can be broadly classified in terms of sample preparation, reactions, and product analysis. Since the reaction products often contain mixtures of multiple chemical species, subsequent analytical steps must be capable of separating and identifying the individual components. Electrophoresis, which relies on inducing detectable differences in migration behavior between charged species under the influence of an applied electric field, has proven to be a highly versatile analytical technique owing to a favorable combination of characteristics including relatively simple hardware design and compatibility with a wide range of analytes including biological macromolecules (e.g., DNA, proteins). More recently, there has been considerable interest in adapting electrophoresis technology to miniaturized microfluidic formats with the aim of producing portable low-cost versions of conventional benchtop-scale instrumentation. Ultimately, it is envisioned that these efforts will enable electrophoresis to become an integral component of self-contained “lab-on-a-chip” devices capable of putting the power to perform a variety of sophisticated chemical, biological, and biomedical assays directly in the hands of those who need the information most.
Postcard: Minimizing Costs on Inter-Datacenter Traffic with Store-and-Forward (2012)

It is typical for cloud providers to operate a number of geographically distributed data centers, where inter-data center traffic constitutes a large portion of a cloud provider's traffic demand over the Internet. Though such inter-data center traffic incurs substantial operational costs that are charged by ISPs, it varies significantly across different overlay links, raising the opportunity to optimize both routing and scheduling of inter-data center traffic to minimize costs. As data is being transmitted multiple sources to their respective destinations, an intermediate data center is also able to store data and forward them at a later time, so that peak traffic demand can be reduced. The cost minimization problem with such store-and-forward is challenging to solve in the general case, due to a large number of variables that determine how data can be sent from a source to a destination, and when should they be "paused" (stored) at an intermediate node, subject to a required maximum transfer time. In this paper, we present Postcard, an online optimization problem carefully formulated to minimize operational costs on inter-data center traffic with store-and-forward at intermediate nodes. To solve the optimization problem with an acceptable number of variables in Postcard, we have simplified the general problem by restricting data transmission to a time-slotted model, such that the problem can be modelled on a time-expanded graph. With extensive simulations, we compare results from solving Postcard to those from solving a flow-based problem without store-and-forward, and present the advantages and drawbacks of store-and-forward when it comes to minimizing costs on inter-data center traffic.
Multi-device Key Management Using Visual Side Channels in Pervasive Computing Environments (2011)

In the modern connected world, pervasive computing has become reality. Thanks to the ubiquity of mobile computing devices and emerging cloud-based services, the users permanently stay connected to their data. This introduces a slew of new security challenges, including the problem of multi-device key management and single-sign-on architectures. One solution to this problem is the utilization of secure side-channels for authentication, including the visual channel as vicinity proof. However, existing approaches often assume confidentiality of the visual channel, or provide only insufficient means of mitigating a man-in-the-middle attack. In this work, we introduce QR-Auth, a two-step, 2D barcode based authentication scheme for mobile devices which aims specifically at key management and key sharing across devices in a pervasive environment. It requires minimal user interaction and therefore provides better usability than most existing schemes, without compromising its security. We show how our approach fits in existing authorization delegation and one-time-password generation schemes, and that it is resilient to man-in-the-middle attacks.
A new physiological concept on cerebellum. (1990)

A general functional model of the cerebellum is proposed based on recent anatomical physiological findings. A cerebellar microcomplex composed of a cortical microzone and a small cell group in a cerebellar or vestibular nucleus acts as an adaptive controller based on the synaptic plasticity of the long-term depression type in Purkinje cells, which is effected by control error signals of climbing fibers. Microcomplexes will be inserted in reflex arcs, command systems of voluntary motor control, and probably even cortical systems performing certain mental activities, providing adaptive-learning capabilities to these systems.
Cell death during sepsis: integration of disintegration in the inflammatory response to overwhelming infection (2009)

Sepsis is a major health problem and a leading cause of death worldwide. In recent years, a crescendo of attention has been directed to the mechanisms of cell death that develop during this disease, since these are viewed as important contributors to the proinflammatory and anti-inflammatory responses associated with poor outcome. Here we discuss mechanisms of cell death evident severe bacterial infection and sepsis including necrosis, apoptosis, pyroptosis, and extracellular trap-associated neutrophil death, with a particular emphasis on lymphocyte apoptosis and its contribution to the immunosuppressed phenotype of late sepsis. Individual bacterial pathogens express virulence factors that modulate cell death pathways and influence the sepsis phenotype. A greater knowledge of cell death pathways in sepsis informs the potential for future therapies designed to ameliorate immune dysfunction in this syndrome.
A variation-aware adaptive voltage scaling technique based on in-situ delay monitoring (2011)

In this paper, we present an adaptive voltage scaling (AVS) scheme to tune the supply voltage of digital circuits according to variations. Compared to worst-case designs, which produce fixed and excessively large safety margins, a considerable amount of energy can be saved by this approach. The AVS technique is based on in-situ delay monitoring, i.e. observing the timing in critical paths. For this task, we propose a Pre-Error flip-flop, that is capable of detecting late data transitions - so-called pre-errors. We provide an in-depth analysis, that is based on a Markov model, to describe the closed loop voltage regulation. We simulated the power saving potential compared to the worst-case design and obtained a reduction of 13.5% in active energy for a negligible error rate of 1E-15. Moreover, we illustrate the opportunity to further reduce the power consumption when tolerating higher error rates. This way, our approach can gain the optimal power saving for a given allowed failure probability.
