Role of transporters in the mechanism of paraquat resistance of horseweed (Conyza canadensis (L.) Cronq.) (2005)

In paraquat resistant biotype of C. canadensis inducible proteins are supposed to play a role in the mechanism of resistance. Here we studied the uptake and intracellular localization of Pq, the effect of selective inhibitors on the uptake and sequestration, and the Pq induced changes of gene expression in susceptible and resistant biotypes. In resistant plants Pq was found to reach the chloroplast in a short time, however, to the end of recovery period it was removed to vacuoles and stored for one month. Sequestration to vacuoles was inhibited by nitrate. Pq upregulated numerous genes in susceptible and resistant biotypes. Sequencing made the opportunity to identify 4 genes; the iron storage protein Ferritin2, a Myb transcription factor, CAT4 amino acid transporter and a xenobiotic transporter. Transporters expressed at higher levels in resistant plants as compared to susceptible ones. They are supposed to play important part in paraquat resistance.
Slow memory: weakening consistency to enhance concurrency in distributed shared memories (2002)

The use of weakly consistent memories in distributed shared memory systems to combat unacceptable network delay and to allow such systems to scale is proposed. Proposed memory correctness conditions are surveyed, and how they are related by a weakness hierarchy is demonstrated. Multiversion and messaging interpretations of memory are introduced as means of systematically exploring the space of possible memories. Slow memory is presented as a memory that allows the effects of writes to propagate slowly through the system, eliminating the need for costly consistency maintenance protocols that limit concurrency. Slow memory processes a valuable locality property and supports a reduction from traditional atomic memory. Thus slow memory is as expressive as atomic memory. This expressiveness is demonstrated by two exclusion algorithms and a solution to M.J. Fischer and A. Michael's (1982) dictionary problem on slow memory.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">&gt;</ETX>
Mast cell activation disease: a concise practical guide for diagnostic workup and therapeutic options (2011)

Mast cell activation disease comprises disorders characterized by accumulation of genetically altered mast cells and/or abnormal release of these cells' mediators, affecting functions in potentially every organ system, often without causing abnormalities in routine laboratory or radiologic testing. In most cases of mast cell activation disease, diagnosis is possible by relatively non-invasive investigation. Effective therapy often consists simply of antihistamines and mast cell membrane-stabilising compounds supplemented with medications targeted at specific symptoms and complications. Mast cell activation disease is now appreciated to likely be considerably prevalent and thus should be considered routinely in the differential diagnosis of patients with chronic multisystem polymorbidity or patients in whom a definitively diagnosed major illness does not well account for the entirety of the patient's presentation.
Physical Properties of Mixed Conductor Solid Oxide Fuel Cell Anodes of Doped CeO2 (1994)

Samples of doped with oxides such as and were prepared. Their conductivities and expansions on reduction were measured at 1000°C, and the thermal expansion coefficients in the range 50 to 1000°C were determined. The ionic and electronic conductivity were derived from curves of total conductivity vs. oxygen partial pressure. For both types of conductivity a dependence on dopant valency was observed. The electronic conductivity was independent of dopant radius in contrast to the ionic which was highly dependent. These measured physical properties are compared with the ideal requirements for solid oxide fuel cell anodes. Not all requirements are fulfilled. Measures to compensate for this are discussed.
Plane-wave ultrasound beamforming using a nonuniform fast fourier transform (2012)

Beamforming of plane-wave ultrasound echo signals in the Fourier domain provides fast and accurate image reconstruction. Conventional implementations perform a k-space interpolation from the uniform sampled grid to a nonuniform acoustic dispersion grid. In this paper, we demonstrate that this step can be replaced by a nonuniform Fourier transform. We study the performance of the nonuniform fast Fourier transform (NUFFT) in terms of signal-to-noise ratio and computational cost, and show that the NUFFT offers an advantage in the trade-off between speed and accuracy, compared with other frequency-domain beamforming strategies.
Blue Thermally Activated Delayed Fluorescence Polymers with Nonconjugated Backbone and Through-Space Charge Transfer Effect (2017)

We demonstrate novel molecular design for thermally activated delayed fluorescence (TADF) polymers based on a nonconjugated polyethylene backbone with through-space charge transfer effect between pendant electron donor (D) and acceptor (A) units. Different from conventional conjugated D-A polymers with through-bond charge transfer effect, the nonconjugated architecture avoids direct conjugation between D and A units, enabling blue emission. Meanwhile, spatial π-π interaction between the physically separated D and A units results in both small singlet-triplet energy splitting (0.019 eV) and high photoluminescence quantum yield (up to 60% in film state). The resulting polymer with 5 mol % acceptor unit gives efficient blue electroluminescence with Commission Internationale de l'Eclairage coordinates of (0.176, 0.269), together with a high external quantum efficiency of 12.1% and low efficiency roll-off of 4.9% (at 1000 cd m<sup>-2</sup>), which represents the first example of blue TADF nonconjugated polymer.
Hyper-NF: synthesizing chains of virtualized network functions (2016)

Middleboxes are essential to the functioning of today's internet. They are for instance used to secure networks, to enhance performances (e.g., throughput, scalability or end-user latency) or to monitor traffic. Although middleboxes are usually deployed through expensive dedicated hardware, the past 15 years has seen the emergence of a new paradigm: network function virtualisation (NFV). In the NFV context, middleboxes are implemented in software on commodity hardware, thus reducing costs and increasing flexibility. Some of the most recent work even boast performances that are equals to those of hardware middleboxes (e.g., line-rate throughput). However, none of the frameworks that we could find were suited to implement chains of virtualised middleboxes. Indeed, it is often the case that a packet must cross numerous middleboxes when traversing the internet. In order for an NFV deployment to scale out and reduce the network overhead, one would wish to be able to deploy all these middleboxes on the same physical machine. We provide an evaluation of a state-of-the-art NFV framework that shows that the throughput of a chain of 8 middleboxes running on the same server can be as much as 5 times smaller than the throughput of a single middlebox. We then introduce Hyper-NF, a new NFV framework specifically designed for implementing chains of virtualised middleboxes. Hyper-NF eliminates redundant packet and I/O operations. Given a chain of middleboxes, it uses graph search and set theory to generate a single equivalent middlebox that only uses one read and one write operation per packet. Experimentation with middlebox deployments inspired from real-world use cases shows that Hyper-NF achieve constant throughput and latency despite the increasing number of chained middleboxes. Thus, it achieves considerably better performances than traditional deployments. On a chain of 8 virtualised middleboxes, Hyper-NF has a 5 times higher throughput, a 10 times lower latency and uses 8.5 times less CPU cycles per packet.
Systemic and intrathecal pharmacologic treatment (2015)

The urinary symptoms of patients with neurogenic bladder usually result from either failure to store urine at low pressure with or without urinary incontinence, or failure to void by complete bladder emptying. They represent the two extremes of a complex functional mechanism relying on an intact neuroanatomic axis. Patients with more profound disturbances may require pharmacologic treatment to reinforce other forms of management, such as clean intermittent catheterization (CIC). Antimuscarinic drugs alone or in combination with CIC are currently the mainstay of conservative treatment of neurogenic bladders. Acetylcholine is a major neurotransmitter involved in detrusor contractions. There are five muscarinic receptor subtypes, each encoded by a different gene. All muscarinic receptor subtype mRNAs have been detected in the human bladder, including the urothelium, interstitial cells, nerve fibers, and detrusor layers. Structural differences divide urologic agents into tertiary and quaternary amines. They also differ in molecular size, charge, and lipophilicity.
Chronic Hypoventilation Syndrome: Treatment with Non-invasive Mechanical Ventilation (1991)

Chronic hypoventilation syndrome can be caused by many disease states, although it is more commonly seen in neuromuscular disorders. Assessment of hypoventilation includes measurement of carbon dioxide level, respiratory muscle strength, pulmonary function testing, and any other system involved, such as cardiac dysfunction or sleep abnormalities. Often, chronic hypoventilation is initially diagnosed during an episode of acute respiratory failure. The use of noninvasive ventilation with positive pressure, negative pressure, or gravitational devices can be an effective treatment option for some patients, thus obviating the need for a tracheostomy. Noninvasive ventilatory equipment such as the nasal or oral masks, mouthpieces, bi-level positive airway pressure, chest cuirasses, ponchos, or the iron lung, and the rocking bed or pneumobelt can each ventilate a certain type of patient adequately. Each has specific indications, advantages, and disadvantages and must be individualized to the patient's needs.
Input current ripple reduction and high efficiency for PEM fuel cell power conditioning system (2017)

To solve the issues of the open-loop control accuracy in a proton exchange membrane (PEM) fuel cell power conditioning system (PCS) with active clamp push-pull DC/DC converter for input current ripple reduction, a novel closed-loop digital-controlled method is proposed. The proposed PEM fuel cell PCS consists of a high-efficiency high-step-up current-fed resonant push-pull DC/DC converter and a half-bridge inverter. A fully digital-controlled strategy in the active-clamped circuit is employed to reduce the voltage spike and low frequency current ripple (LFCR) on the power switches for improving the lifespan of PEM fuel cell and raising the system reliability. By using the closed-loop current ripple reduction control, the LFCR is further reduced. A 300 W prototype is implemented and tested. Experimental results show that the minimum efficiency at full load is about 94.8% and the ripple current is less than 1.2% of the rated input current.
An unsupervised approach for recurrent tv program structuring (2011)

This paper addresses the problem of unsupervised TV program structuring. Program structuring allows to improve browsing and interaction with TV programs. Our work addresses the structuring of recurrent TV programs like entertainment programs, shows, magazines... It relies on the automatic detection of separators in programs using a repeated sequence detection method that is applied over a set of episodes of the same TV program. Separators are short sequences that are inserted between different parts of a program and that are repeated between and/or within the episodes of the same program. The effectiveness of the approach has been evaluated over 54 episodes of daily TV programs.

Selective weakening and post-tensioning for retrofit of non-ductile R.C. exterior beam-column joints (2010)

A counter-intuitive “selective weakening” (SW) seismic retrofit strategy for non-ductile RC frame is presented. By focusing on increasing the global displacement and ductility capacity, simple retrofit interventions such as selective weakening of the beams and external post-tensioning of the beam-column joints could change the local inelastic mechanism and result in improved global lateral and energy dissipation capacities. After an overview of the SW retrofit concept, this paper presents the experimental and numerical investigations of SW retrofit techniques for non-ductile RC exterior joints. The experimental results of nine 2/3-scaled exterior joint subassemblies– as-built and SW retrofitted tests are briefly presented. Parameters considered in the tests included the presence of column lap-splice, slab and transverse beams, level of post-tensioning forces and location of beam weakening. Numerical investigation using 3D micro-plane concrete model within smeared fracture mechanics finite-element modelling is demonstrated for SW retrofitted joints. Lastly, a preliminary design procedure is outlined for the design of SW retrofit for exterior beam-column joints. With its economical, non-invasive and low-technology intensity approach, SW retrofit has potential for a wide implementation.
Rheology and Transport in Porous Media of New Water Shutoff/Conformance Control Microgels (2005)

Abstract The performances of new microgels specifically designed for water shutoff and conformance control were extensively investigated at laboratory scale. These microgels are preformed, stable, fully water soluble, size controlled with a narrow size distribution, and non-toxic. They reduce water permeability by forming adsorbed layers soft enough to be very easily collapsed by oil-water capillary pressure, so that oil permeability is not significantly affected. Since the manufacturing process of these new microgels make possible to vary chemical composition, size and crosslink density, they can be designed as desired to meet the requirements of a given field application. The laboratory results reported in this paper concerns mainly three microgel samples having significantly different crosslink densities. We describe the relevant laboratory methods used to determine main microgel characteristics. The microgels have remarkable mechanical, chemical and thermal stability. Their behavior in porous media have been investigated extensively, showing that: 1) their propagation distance is only limited by the volume injected, 2) their injectivity is facilitated by a shear-thinning behavior and 3) water permeability reduction can be achieved as desired by controlling the thickness of adsorbed layer. Thus, this new microgels, now available at industrial scale, look as very promising tools, not only for water shutoff but also for conformance control in heterogeneous reservoirs.
Development of a Nitride Dispersion Strengthened (NDS) Metallic Alloy for High-Temperature Recuperators (1985)

Abstract : The objective of this program was to demonstrate the feasibility of using nitride dispersion strengthened (NDS) stainless steel in fabricating a recuperator for advanced gas turbine engines. Test results showed an alloy-- designated NDS 300--to have tensile properties comparable to those of Inconel 625 at temperatures up to 1650 F, and at higher temperatures the properties of the NDS alloy exceeded those of the Inconel 625. However, creep test results showed a three-fold improvement in strength of NDS 300 over Inconel 625 at temperatures above 1500 F. The NDS material demonstrated adequate formability and joinability by brazing with a filler metal of nominal composition Ni-19Cr- 10Si (J8100). The same filler metal proved to be a good coating for high- temperature oxidation resistance. Tests on specimens prepared to a typical plate-fin recuperator configuration confirmed the strength of the brazing alloy and demonstrated the marked superiority of the NDS material over Inconel 625. Keywords: Heat exchanger; Recuperator; Nitriding.

Indium Oxide/Carbon Nanotube/Reduced Graphene Oxide Ternary Nanocomposite with Enhanced Electrochemical Supercapacitance (2018)

Abstract Electrochemical supercapacitance performance of a ternary nanocomposite composed of mesoporous indium oxide (In2O3) nanocube crystals (size ∼50 nm) embedded in carbon nanotubes (CNT) and reduced graphene oxide (RGO) prepared by hydrothermal method is reported. A glassy carbon electrode modified with the In2O3/CNT/RGO nanocomposite material exhibited excellent electrochemical performance with a large specific capacitance of 1273 F g−1 at 5 mV s−1 and 948 F g−1 at 1 A g−1. The composite electrode showed excellent cyclic stability without any capacity loss after 5000 charge/discharge cycles. Furthermore, ∼75% capacitance retention was observed at high scan rate of 200 mV s−1. These results indicate that the novel mesoporous In2O3 cubes composited with π-electron rich conductive nanocarbons CNT and RGO would be useful as electrode material for advanced supercapacitors.
Self-Consistent Enhanced S/D Tunneling Implementation in a 2D MS-EMC Nanodevice Simulator (2021)

The implementation of a source to drain tunneling in ultrascaled devices using MS-EMC has traditionally led to overestimated current levels in the subthreshold regime. In order to correct this issue and enhance the capabilities of this type of simulator, we discuss in this paper two alternative and self-consistent solutions focusing on different parts of the simulation flow. The first solution reformulates the tunneling probability computation by modulating the WKB approximation in a suitable way. The second corresponds to a change in the current calculation technique based on the utilization of the Landauer formalism. The results from both solutions are compared and contrasted to NEGF results from NESS. We conclude that the current computation modification constitutes the most suitable and advisable strategy to improve the MS-EMC tool.
Numerical simulation of large deformation polycrystalline plasticity (2000)

A finite element model based on crystal plasticity has been developed to simulate the stress-strain response of sheet metal specimens in uniaxial tension. Each material point in the sheet is considered to be a polycrystalline aggregate of FCC grains. The Taylor theory of crystal plasticity is assumed. The numerical analysis incorporates parallel computing features enabling simulations of realistic models with large number of grains. Simulations have been carried out for the AA3004-H19 aluminium alloy and the results are compared with experimental data. (author)

Superior Short Circuit Performance of 1.2kV SiC JBSFETs Compared to 1.2kV SiC MOSFETs (2019)

The high-temperature switching performance of a 1.2kV SiC JBSFET is compared with a 1.2kV SiC MOSFET using a clamped inductive load switching circuit representing typical H-bridge inverters. The switching losses of the SiC MOSFET are also evaluated with a SiC JBS Diode connected antiparallel to it. Measurements are made with different high-side and low-side device options across a range of case temperatures. The JBSFET is observed to display a reduction in peak turn-on current – up to 18.9% at 150°C and a significantly lesser turn-on switching loss – up to 46.6% at 150°C, compared to the SiC MOSFET.
Simultaneous optimization of the cavity heat load and trip rates in linacs using a genetic algorithm (2014)

In this paper, a genetic algorithm-based optimization is used to simultaneously minimize two competing objectives guiding the operation of the Jefferson Lab's Continuous Electron Beam Accelerator Facility linacs: cavity heat load and radio frequency cavity trip rates. The results represent a significant improvement to the standard linac energy management tool and thereby could lead to a more efficient Continuous Electron Beam Accelerator Facility configuration. This study also serves as a proof of principle of how a genetic algorithm can be used for optimizing other linac-based machines.
