Dynamic Voltage and Frequency Scaling Architecture for Units Integration within a GALS NoC (2008)

In complex embedded applications, optimization and adaptation at run time of both dynamic and leakage power have become an issue at SoC coarse grain. For power reduction, voltage and frequency scaling techniques have been applied successfully to CPUs but never with a generic approach for all IPs within a SoC. Network-on-Chip architecture combined with a Globally Asynchronous Locally Synchronous paradigm is a natural enabler for easy IP unit integration. GALS NoC provides scalable communications and a clear split between timing domains. We propose in this paper a complete Dynamic Voltage and Frequency Scaling architecture for IP units integration within a GALS NOC. The proposed DVFS architecture is based on the association of Local clock generator and VDD-Hopping between two given voltages. No fine control software is required during any voltage and frequency re-programming. As a result, minimal latency cost is observed. The power efficiency of the proposed system has been evaluated close to 95%.
Channel capacity of Middleton's class A interference channel (2009)

Middleton&apos;s class A interference model has properties that make it possible to represent a wide class of interference signals. By choice of model parameters, interference signals ranging from pure Gaussian distributed to pure impulsive interference can be modelled. These properties make the model very useful for a large variety of applications. However, an expression for the channel capacity of the class A interference channel has not yet been published. The channel capacity of this model is derived, and numerical examples are given for some useful sets of model parameters.
Atomic rearrangement of a sputtered MoS2 film from amorphous to a 2D layered structure by electron beam irradiation (2017)

We synthesised a crystalline MoS<sub>2</sub> film from as-sputtered amorphous film by applying an electron beam irradiation (EBI) process. A collimated electron beam (60 mm dia.) with an energy of 1 kV was irradiated for only 1 min to achieve crystallisation without an additional heating process. After the EBI process, we observed a two-dimensional layered structure of MoS<sub>2</sub> about 4 nm thick and with a hexagonal atomic arrangement on the surface. A stoichiometric MoS<sub>2</sub> film was confirmed to grow well on SiO<sub>2</sub>/Si substrates and include partial oxidation of Mo. In our experimental configuration, EBI on an atomically thin MoS<sub>2</sub> layer stimulated the transformation from a thermodynamically unstable amorphous structure to a stable crystalline nature with a nanometer grain size. We employed a Monte Carlo simulation to calculate the penetration depth of electrons into the MoS<sub>2</sub> film and investigated the atomic rearrangement of the amorphous MoS<sub>2</sub> structure.
Enhanced metal exsolution at the non-polar (001) surfaces of multi-faceted epitaxial thin films (2022)

Abstract Metal exsolution is a dynamic process driven under a reducing atmosphere and at elevated temperatures that results in the self-assembly of nanoparticles at the surface of complex perovskite catalysts. The nanoparticle characteristics of metal exsolution catalysts can be subject to considerable inhomogeneity, and the anisotropic surface properties of ceramic oxides have been identified to have a major influence on the exsolution behavior. We systematically reveal the orientation-dependent anisotropy of the exsolution behavior of Ni in SrTi 0.9 Nb 0.05 Ni 0.05 O 3−δ using multi-faceted epitaxial thin films that represent a material system with properties in between functional ceramics and single-crystalline perovskite thin film model systems. Using an approach of combined orientation mapping and surface imaging we study the exsolution behavior with particular focus on the initial exsolution response, i.e. after short annealing times. We find orientation-specific variations in the surface morphology of the thin film facets. In the as-prepared state, surface reconstructions cause the formation of patterned surface structures for all thin film facets apart from (001) surfaces, which exhibit a plain surface morphology as well as an enhanced exsolution response. Surface reconstructions and their inherent energy landscape may hence cause an additional energy barrier for the exsolution reaction that results in orientation-dependent differences in the exsolution kinetics.

Epoxy‐based networks combining chemical and supramolecular hydrogen‐bonding crosslinks (2010)

Abstract We combine the supramolecular chemistry of heterocyclic ureas with the chemistry of epoxides to synthesize new crosslinked materials incorporating both chemical and supramolecular hydrogen‐bonded links. A two‐step facile and solvent‐free procedure is used to obtain chemically and thermally stable networks from widely available ingredients: epoxy resins and fatty acids. The density of both chemical and physical crosslinks is controlled by the stoichiometry of the reactants and the use of a proper catalyst to limit side reactions. Depending on the stoichiometry, a wide range of thermomechanical properties can be attained. The method can be used to produce elastomeric objects of complex shapes. © 2010 Wiley Periodicals, Inc.

Enhancing Magnetic Dipole Emission by a Nano-Doughnut-Shaped Silicon Disk (2017)

High-index dielectric nanostructures support inherently strong magnetic dipole (MD) resonances at optical frequencies with minimal dissipative absorptions. They are promising candidates for MD radiation enhancement. Previous investigations, however, show that the maximum magnetic field enhancement is confined inside the nanostructure and therefore inaccessible to nearby MD emitters, limiting the achievable emission enhancement. In this paper, we design a nano-doughnut-shaped silicon disk, i.e., a disk with an open hole through its center. This way, the maximum magnetic field intensity is exposed and can be leveraged to fully enhance MD radiations. On the basis of numerical calculations, a record high enhancement factor of the radiative decay rate up to 350 has been achieved with minimal nonradiative losses. We further demonstrate the importance of spectral and spatial overlap of the MD emitter with the MD resonance in the silicon nanodisk in order to maximize the MD radiations. Our study opens new possibilities for MD emission enhancement and paves the road toward novel magnetic light–matter interactions.

Rinse additives for defect suppression in 193-nm and 248-nm lithogrophy (2004)

Satellite spot defects are a class of defects widely observed in photoresist processing in 248 nm and 193 nm lithography. These defects become more and more significant as the feature sizes shrink and can potentially become “killer” defects, leading to bridging between lines and/or blocking vias. Traditional potential solutions (i.e., optimization of development rinse step) have yielded improvements in the past but did not eliminate the problem. The use of water-soluble topcoat layers was shown to eliminate these defects but it imposes limitations on throughput and cost and it is incompatible with 157 nm lithography and 193 nm immersion schemes. In this work, we report the use of aqueous surfactant solutions for the suppression of defects in 248 nm and 193 nm lithography, with emphasis on satellite spot defects. Suppression of total defects by up to ~99% and practically complete elimination of satellite spot defects were achieved by use of aqueous surfactant solutions for various resists. A handful of materials that can be incorporated into rinse solution for the successful elimination of blob defects in a variety of resists were identified. It was determined that the two most important factors that enable successful defect elimination are the surfactant concentration and the extent of surfactant adsorption to specific resist systems.

Abstract Compaction in the formation surrounding a well borehole can occur after fluid or gas production if the surrounding rock matrix is unable to support the increased burden from overlaying sediments.
Fabrication of Superhydrophobic Surface from a Supramolecular Organosilane with Quadruple Hydrogen Bonding (2004)

A supramolecular organosilane, 2-(3-(triethoxysilyl)propylaminocarbonylamino)-6-methyl-4[1H]pyrimidinone comprising quadruple hydrogen bonds has been synthesized in one step from commercially available starting materials. The synthesized supramolecular organosilane can be stabilized and phase-separated by dimerization via the linear array of quadruple hydrogen bonds in solution. This property of the supramolecular organosilane has been exploited to fabricate structuring materials having a superhydrophobic surface property. We have successfully generated the interconnected granular structure with adequate roughness for superhydrophobicity via sol-gel process.

SYNTHESIS OF DIALKYL (PYRROLIDIN-2-YL)-PHOSPHONATES BY MERCURIC ACETATE PROMOTED CYCLIZATION OF α-AMINOALKENYLPHOSPHONATES. REGIO AND STEREOCHEMICAL ASPECTS (1994)

Abstract A new series of dialkyl(pyrrolidin-2-yl)phosphonates was synthesized by regiospecific intramolecular aminomercuration of α-amino alkenylphosphonates followed by sodium borohydride reduction. The formation of dialkyl (2,5-dialkyl pyrrolidin-2-yl) and dialkyl (5-alkyl pyrrolidin-2-yl)phosphonates was stereoselective and the stereochemistry of diastereomers was assigned using X-ray analysis and 1H, 13C and 31P-NMR data. EPR evidence for the production of free radicals during the borohydride reduction of the intermediate organomercurials was achieved by spin-trapping experiments.

Magnetic Plotter (2017)

This paper presents a method for designing tactile macrotextures with magnetic rubber sheets. In the method, named "Magnetic Plotter", a desktop digital plotting machine combined with a tiny neodymium magnet writes fine magnetic patterns on the surface of the magnetic rubber sheets. This method enables users to design magnetic fields freely with inexpensive commercially available materials as if they are drawing pictures. Moreover, when the magnetic sheets are rubbed together, unique haptic stimuli are displayed on the fingers. The haptic stimuli can be changed by the magnetic patterns designed on the rubber sheets. We developed a prototype of the Magnetic Plotter and investigated the range of the generated haptic stimuli and the texture design possibilities.
Impact of Tire Compliance Behavior to Vehicle Longitudinal Dynamics and Control (2007)

Empirical tire models, generally obtained through lab tests, are commonly used in vehicle dynamics and control analysis. Most of the empirical tire models describe the linear (or nonlinear) static tire behavior and overlook the tire compliance with one exception: the relaxation length tire (RLT) model inserts first order tire dynamics. However, the RLT model creates an undamped oscillation when describing the low-speed tire dynamics. This paper presents an improved longitudinal tire model that describes the tire compliance without exhibiting the undamped vibrations. By incorporating this improved tire model into a vehicle longitudinal model, the dominant flexible modes of the vehicle can be easily captured. The predictions from the improved vehicle model show that the often-ignored tire compliance can impact longitudinal ride comfort and vehicle control designs. Experiments were conducted on a passenger car as an example and the experimental data verified the model predictions.

El crecimiento exponencial del trafico de datos es uno de los mayores desafios que enfrentan actualmente los sistemas de comunicaciones, debiendo los mismos ser capaces de soportar velocidades de procesamiento de datos cada vez mas altas. En particular, el consumo de potencia se ha transformado en uno de los parametros de diseno mas criticos, generando la necesidad de investigar el uso de nuevas arquitecturas y algoritmos para el procesamiento digital de la informacion. Por otro lado, el analisis y evaluacion de nuevas tecnicas de procesamiento presenta dificultades dadas las altas velocidades a las que deben operar, resultando frecuentemente ineficiente el uso de la simulacion basada en software como metodo. En este contexto, el uso de electronica programable ofrece una oportunidad a bajo costo donde no solo se evaluan nuevas tecnicas de diseno de alta velocidad sino tambien se valida su implementacion en desarrollos tecnologicos.

Cytosolic proline is required for basal freezing tolerance in Arabidopsis (2021)

The amino acid proline accumulates in many plant species under abiotic stress conditions, and various protective functions have been proposed. During cold stress, however, proline content in Arabidopsis thaliana does not correlate with freezing tolerance. Freezing sensitivity of a starchless plastidic phosphoglucomutase mutant (pgm) indicated that localization of proline in the cytosol might stabilize the plasma membrane during freeze-thaw events. Here, we show that re-allocation of proline from cytosol to vacuole was similar in the pyrroline-5-carboxylate synthase 2-1 (p5cs2-1) mutant and the pgm mutant and caused similar reduction of basal freezing tolerance. In contrast, the starch excess 1-1 mutant (sex1-1) had even lower freezing tolerance than pgm but did not affect sub-cellular localization of proline. Freezing sensitivity of sex1-1 mutants affected primarily the photosynthetic electron transport and was enhanced in a sex1-1::p5cs2-1 double mutant. These findings indicate that several independent factors determine basal freezing tolerance. In a pgm::p5cs2-1 double mutant, freezing sensitivity and proline allocation to the vacuole were the same as in the parental lines, indicating that the lack of cytosolic proline was the common cause of reduced basal freezing tolerance in both mutants. We conclude that cytosolic proline is an important factor in freezing tolerance of non-acclimated plants.
Intra‐volume, centralised array concept for improved public‐safety communications (2013)

The author report on the testing and measurements of an intra‐volume centralised array concept suitable for public‐safety communications in buildings. The centralised array concept refers to the use of several small communication devices that are arbitrarily placed in an area and hence create a real‐time communication network. The overall concept is to use randomly located (or arbitrarily placed) wireless devices in a coordinated manner in order to increase the radio‐frequency signal level otherwise at unreachable locations. In a typical ad‐hoc network, the transmission range of any communication link in that path is limited. We seek to extend the radio‐frequency coverage within the array volume by using two or more nodes as elements of a phased array. The measurement results presented here, collected in real‐world environments, along with simulations based on real‐world data demonstrate that the centralised array technique can provide useful gain, up to 10 dB with only four elements. Both the measurements and simulations also indicate a typical gain of 2 to 6 dB, using only two elements. Analysis of the phase indicates a phase alignment of ±45° achieves within 1 dB of the maximum gain.

Lysosomal calcium homeostasis defects, not proton pump defects, cause endo-lysosomal dysfunction in PSEN-deficient cells (2012)

Presenilin (PSEN) deficiency is accompanied by accumulation of endosomes and autophagosomes, likely caused by impaired endo-lysosomal fusion. Recently, Lee et al. (2010. Cell. doi: http://dx.doi.org/10.1016/j.cell.2010.05.008) attributed this phenomenon to PSEN1 enabling the transport of mature V0a1 subunits of the vacuolar ATPase (V-ATPase) to lysosomes. In their view, PSEN1 mediates the N-glycosylation of V0a1 in the endoplasmic reticulum (ER); consequently, PSEN deficiency prevents V0a1 glycosylation, compromising the delivery of unglycosylated V0a1 to lysosomes, ultimately impairing V-ATPase function and lysosomal acidification. We show here that N-glycosylation is not a prerequisite for proper targeting and function of this V-ATPase subunit both in vitro and in vivo in Drosophila melanogaster. We conclude that endo-lysosomal dysfunction in PSEN(-/-) cells is not a consequence of failed N-glycosylation of V0a1, or compromised lysosomal acidification. Instead, lysosomal calcium storage/release is significantly altered in PSEN(-/-) cells and neurons, thus providing an alternative hypothesis that accounts for the impaired lysosomal fusion capacity and accumulation of endomembranes that accompanies PSEN deficiency.
Securing Robot-assisted Minimally Invasive Surgery through Perception Complementarities (2020)

Laparoscopic surgery presents practical benefits over traditional open surgery, including reduced risk of infection, discomfort and recovery time for patients. Introducing robot systems into surgical tasks provides additional enhancements, including improved precision, remote operation, and an intelligent software layer capable of filtering aberrant motion and scaling surgical maneuvers. However, the software interface in telesurgery also lends itself to potential adversarial cyber attacks. Such attacks can negatively effect both surgeon motion commands and sensory information relayed to the operator. To combat cyber attacks on the latter, one method to enhance surgeon feedback through multiple sensory pathways is to incorporate reliable, complementary forms of information across different sensory modes. Built-in partial redundancies or inferences between perceptual channels, or perception complementarities, can be used both to detect and recover from compromised operator feedback. In surgery, haptic sensations are extremely useful for surgeons to prevent undue and unwanted tissue damage from excessive tool-tissue force. Direct force sensing is not yet deployable due to sterilization requirements of the operating room. Instead, combinations of other sensing methods may be relied upon, such as noncontact model-based force estimation. This paper presents the design of a surgical simulator software that can be used for vision-based non-contact force sensing to inform the perception complementarity of vision and force feedback for telesurgery. A brief user study is conducted to verify the efficacy of graphical force feedback from vision-based force estimation, and suggests that vision may effectively complement direct force sensing.
Parity violation in neutron resonances in115In (2000)

Parity nonconservation (PNC) was studied in p-wave resonances in indium by measuring the helicity dependence of the neutron total cross section in the neutron energy range 6.0--316 eV with the time-of-flight method at LANSCE. A total of 36 p-wave neutron resonances were studied in ${}^{115}\mathrm{In},$ and statistically significant asymmetries were observed for nine cases. An analysis treating the PNC matrix elements as random variables yields a weak matrix element of ${M=(0.67}_{\ensuremath{-}0.12}^{+0.16}) \mathrm{meV}$ and a weak spreading width of ${\ensuremath{\Gamma}}_{w}{=(1.30}_{\ensuremath{-}0.43}^{+0.76})\ifmmode\times\else\texttimes\fi{}{10}^{\ensuremath{-}7} \mathrm{eV}.$
