A modified Flash-EEPROM device is presented. This device operates as a non-volatile programmable pass transistor. Program and erase, operations are performed on a Flash-EEPROM cell coupled to a ...pass-transistor. Written and erased states of the flash cell correspond to the open and close states of the pass-transistor respectively. The Flash-programmable pass transistor (FPT) was developed for multi-context programmable-logic, and it was realized in a technology for embedded Flash-EEPROM NOR memory. No additional process steps are required. This novel device has the same program and erasing behavior as the standard Flash-EEPROM cell, measurements are reported for a 0.18 /spl mu/m technology implementation.
The hadronic final states observed with the ALEPH detector at LEP in e+e- annihilation are analysed using 730 pb-1 of data collected between 91 and 209 GeV in the framework of QCD. In particular ...event-shape variables and inclusive charged particle spectra are measured. The energy evolution of quantities derived from these measurements is compared to analytic QCD predictions. The mean charged particle multiplicity, the charged particle momentum spectrum and its peak position are compared to predictions of the modified-leading-logarithmic approximation. The strong coupling constant alpha_s is determined from a fit of the QCD prediction to distributions of six event-shape variables at eight centre-of-mass energies. A study of non-perturbative power law corrections is presented
A charge-pump architecture is presented with an improved power efficiency and a high voltage output compared to the known Dickson and Favrat architectures due to partial reuse of the charge stored on ...the capacitors. An 8-stage charge pump fabricated in a 0.13 μm CMOS process has a 1.2V supply and a 100MHz clock. The measured performance indicates that the efficiency can be 25% higher than a Favrat cell. The efficiency increases with the number of stages, reaching 60% with 10 stages.

An analog CAM based on analog flash technology has been developed for pattern recognition applications. The chip uses analog flash technology for data storage, programmable on-chip references and ...offset compensation and is capable of performing 55GCPS at 195 mW. It has an overall system-level precision of 6 b on a real-world environment.
Beta-endorphin appears to be involved in the hormonal response to suckling in some animals. The peripheral secretory patterns of beta-endorphin, prolactin and cortisol were investigated in serial ...venous blood samples taken during suckling from eight healthy women who were breast-feeding on the third or fourth day of the puerperium. Plasma levels of prolactin and beta-endorphin increased significantly during suckling reaching a peak after 20 min, levels of cortisol remained unaffected. It is suggested that the increased beta-endorphin derives from an extra-hypophyseal source.
This paper describes a digital signal processor based on a multi-context, dynamically reconfigurable datapath, suitable for inclusion as an IP-block in complex SoC design projects. The IP was ...realized in CMOS 090 nm technology. The most relevant features offered by the proposed architecture with respect to state of the art are zero overhead for switching between successive configurations, relevant area and energy computational density on computational kernels (average of 2 GOPS/mm 2 , 0.2GOPS/mW) and relatively small area occupation (18 mm 2 ), making it suitable for acceleration or upgrade of multi-core heterogeneous embedded platforms. The processor is delivered with a software tool chain providing the application developer algorithmic analysis and design space exploration based on ANSI C, with no utilization of hardware-related constructs or description languages
Coronary artery disease, CAD, is associated with both narrowing of the epicardial coronary arteries and microvascular disease, thereby limiting coronary flow and myocardial perfusion. CAD accounts ...for almost 2 million deaths within the European Union on an annual basis. In this paper, we review the physiological and pathophysiological processes underlying clinical decision making in coronary disease as well as the models for interpretation of the underlying physiological mechanisms. Presently, clinical decision making is based on non-invasive magnetic resonance imaging, MRI, of myocardial perfusion and invasive coronary hemodynamic measurements of coronary pressure and Doppler flow velocity signals obtained during catheterization. Within the euHeart project, several innovations have been developed and applied to improve diagnosis-based understanding of the underlying biophysical processes. Specifically, MRI perfusion data interpretation has been advanced by the gradientogram, a novel graphical representation of the spatiotemporal myocardial perfusion gradient. For hemodynamic data, functional indices of coronary stenosis severity that do not depend on maximal vasodilation are proposed and the Valsalva maneuver for indicating the extravascular resistance component of the coronary circulation has been introduced. Complementary to these advances, model innovation has been directed to the porous elastic model coupled to a one-dimensional model of the epicardial arteries. The importance of model development is related to the integration of information from different modalities, which in isolation often result in conflicting treatment recommendations.
The effects of suckling on plasma somatostatin, insulin and gastrin values were evaluated in eight nursing women on the 3rd to 4th day postpartum. Plasma prolactin levels were also determined. ...Prolactin levels increased in response to suckling, as expected. Insulin levels also rose, whereas somatostatin and gastrin concentrations did not change after suckling. It is possible that the suckling-induced hyperinsulinemia blunts the somatostatin response to suckling in humans.
