An efficient method for evaluating polynomial and rational function approximations (2008)

In this paper we extend the domain of applicability of the E-method [7, 8], as a hardware-oriented method for evaluating elementary functions using polynomial and rational function approximations. The polynomials and rational functions are computed by solving a system of linear equations using digit-serial iterations on simple and highly regular hardware. For convergence, these systems must be diagonally dominant. The E-method offers an efficient way for the fixed-point evaluation of polynomials and rational functions if their coefficients conform to the diagonal dominance condition. Until now, there was no systematic approach to obtain good approximations to f over an interval [a, b] by rational functions satisfying the constraints required by the E-method. In this paper, we present such an approach which is based on linear programming and lattice basis reduction. We also discuss a design and performance characteristics of a corresponding implementation.

Acute Respiratory Distress Syndrome in Blunt Trauma: Identification of Independent Risk Factors (2002)

Acute respiratory distress syndrome (ARDS) is a major contributor to morbidity and mortality in trauma patients. Although many injuries and conditions are believed to be associated with ARDS independent risk factors in trauma patients and their relative importance in development of the syndrome are undefined. The aim of this project is to identify independent risk factors for the development of ARDS in blunt trauma patients and to examine the contributions of each factor to ARDS development. Patients with ARDS were identified from the registry of a Level I trauma center over a 4.5-year period. Records were reviewed for demographics, injury characteristics, transfusion requirements, and hospital course. Variables examined included age >65 years, Injury Severity Score (ISS) >25, hypotension on admission (systolic blood pressure <90), significant metabolic acidosis (base deficit <-5.0), severe brain injury as shown by a Glasgow Coma Scale score (GCS) <8 on admission, 24-hour transfusion requirement >10 units packed red blood cells, pulmonary contusion (PC), femur fracture, and major infection (pneumonia, empyema, or intra-abdominal abscess). Both univariate and stepwise logistic regression were used to identify independent risk factors, and receiver operating characteristic curve (ROC) analysis was used to determine the relative contribution of each risk factor. A total of 4397 patients having sustained blunt trauma were admitted to the intensive care unit and survived >24 hours between October 1995 and May 2000. Of these patients 200 (4.5%) developed ARDS. All studied variables were significantly associated with ARDS in univariate analyses. Stepwise logistic regression, however, demonstrated age >65 years, ISS >25, hypotension on admission, 24-hour transfusion requirement >10 units, and pulmonary contusion as independent risk factors, whereas admission metabolic acidosis, femur fracture, infection, and severe brain injury were not. Using a model based on the logistic regression equation derived yields better than 80 per cent discrimination in ARDS patients. The risk factors providing the greatest contribution to ARDS development were ISS >25 (ROC area 0.72) and PC (ROC area 0.68) followed by large transfusion requirement (ROC area 0.56), admission hypotension (ROC area 0.57), and age >65 (ROC area 0.54). Independent risk factors for ARDS in blunt trauma include ISS >25, PC, age >65 years, hypotension on admission, and 24-hour transfusion requirement >10 units but not admission metabolic acidosis, femur fracture, infection, or severe brain injury. Assessment of these variables allows accurate estimate of risk in the majority of cases, and the most potent contributors to the predictive value of the model are ISS >25 and PC. Improvement in understanding of which patients are actually at risk may allow for advances in treatment as well as prevention in the future.
Production and characterization of monoclonal antibodies against aflatoxin M1 (1984)

By using an indirect enzyme-linked immunosorbent assay, four monoclonal antibodies were selected after fusion of mouse P3-NS1-Ag4-1 myeloma cells with spleen cells isolated from BALB/c mice that had been immunized with aflatoxin M1 (AFM1) conjugated to bovine serum albumin. Two of these antibodies were found to be specific for AFM1 and were designated AMW-1 and AMW-4. The specificities of AMW-1, which had higher affinity to AFM1, were determined by a competitive direct enzyme-linked immunosorbent assay with peroxidase-AFM1 as the marker. The relative cross-reactivity of each toxin (relative to AFM1) with AMW-1, as determined by the amount of aflatoxin necessary to cause 50% inhibition of enzyme activity, was 12, greater than 40, 12, and greater than 40 for B1, B2, G1, and G2, respectively.

A Comparison of Heavy-Duty Diesel Truck Engine Smoke Opacities at High Altitude and at Sea Level (1991)

<div class="htmlview paragraph">A study was conducted by the California Air Resources Board to investigate the effects that altitude has on in-use heavy-duty diesel truck smoke opacities. The understanding of these effects may allow for the establishment of a high altitude opacity standard for diesel trucks operating at or above altitudes of 5800 feet. During a three-week study, 170 heavy-duty diesel trucks were tested at an altitude of 5,820 feet using a test procedure consisting of rolling acceleration and snap idle tests. Eighty-four (84) of these trucks were recaptured and retested at an altitude of 125 feet. Results from a regression analysis indicates that, on average, truck smoke opacities increased by 23 opacity points when tested at altitudes near 6000 feet. Possible high altitude cutpoints and failure rates are also discussed.</div>

Sequential Ni-Catalyzed Borylation and Cross-Coupling of Aryl Halides via in Situ Prepared Neopentylglycolborane (2008)

A procedure for NiCl(2)(dppp)-catalyzed pinacolborylation and neopentylglycolborylation that utilizes in situ prepared inexpensive pinacolborane and neopentylglycolborane is reported. The scope of this reaction was demonstrated with a variety of aryl bromides and iodides. The resulting aryl neopentylglycolboronic esters undergo a NiCl(2)(dppe)-catalyzed cross-coupling with aryl halides, resulting in an extremely efficient and cost-effective method for the synthesis of functional biaryls, dendritic building blocks, and other complex architectures.
Optimization of Disc Parameters Producing More Suitable Size Range of Green Pellets (2012)

Pellet ization is an agglomeration technique, beneficial with finer iron ores over other agglomeration processes. For Co rex and Blast furnace feed, a certain size range of pellets is required for attaining the operating bed permeability along with other fu rnace parameters for s mooth operation. The size distribution of pellets main ly depends on the nature of raw materials, balling equip ment, disc inclination, disc rotating speed, rim height, size o f the feed, feed rate, amount of mo isture added, nozzle co mbination and position, residence time in disc pellet izer etc. The present work is aimed at to optimize the operating parameters imp roving the disc pelletizer efficiency which can enable to choose more suitable green pellets size range (8-12) so as to improve the plant productivity and minimizing the oversize and undersized green pellets. Experiments were conducted with varying disc inclination, disc rotation, nozzle co mbination or position and feed rate keeping other parameters constant to produce the desired size range (8-12 mm) pellets. The properties viz, green co mp ressive strength (GCS), drop strength, moisture content, loss on ignition (LOI) of green pellet were tested and recorded. The experimental observation shows that finer the particle size, more the compactness and thereby, higher the green compressive strength and drop strength of pellets. The disc inclination of 430 is the optimu m value at wh ich maximu m efficiency of balling disc was observed. At higher feed rate, the disc rp m needs to be increased to nullify the effect of decreased required size range. At JSW Steel Ltd., upon implementation at pellet plant the benefits are as under. i)Production of indurated pellet increased by 95 t/day (i.e., ~ 0.9%). ii)Recirculat ion load of under/over size pellets reduced from 20.06 to 11.55 %. iii)Unfired pellets reduced fro m 8.47 to 5.90 %.
Design Flow for High Switching Frequency and Large-Bandwidth Analog DC/DC Step-Down Converters for a Polar Transmitter (2011)

System-on-chip requirements for energy management push both technology and design of voltage regulators to their limits. Integration constraints are added to high performance needs in terms of power efficiency and dynamic performance of the power converters. Switch-mode power supplies (SMPSs) are intended to supplant linear voltage regulators. This paper details a methodology to deal with different tradeoffs introduced by various specifications and constraints of embedded SMPSs. The design methodology is applied to the standard analog step-down SMPS architecture operating at very high switching frequency, and verified experimentally. The results are measured on test chips fabricated in standard 0.25-m BiCMOS technology, operating between 10 and 200 MHz, respectively, with a power efficiency up to 80% and a small-signal bandwidth of 1.2 and 15 MHz, respectively.
Electrochemistry and Electrogenerated Chemiluminescence of Quinoxaline Derivatives (2008)

We report the electrochemistry, spectroscopy, and electrogenerated chemiluminescence (ECL) of donor−acceptor compounds containing a quinoxaline derivative as the central core coupled with fluorene (CFPQ, CFPP, and MFPQ) and triphenylamine moieties (MAPQ). Cyclic voltammetry of all four derivatives show reversible reduction waves (assigned to the formation of the radical anion) localized in the quinoxaline moiety (the acceptor group), whereas oxidation waves show behavior that depends upon the nature of the donor group. With a pair of strong donor groups, triphenylamine, (MAPQ), exhibits a two electron oxidation wave due to the two noninteracting donor moieties. The fluorene derivatives (CFPQ, CFPP, and MFPQ) show less reversible oxidation waves at scan rates of 100 mV/s, but CFPP and CFPQ become reversible at higher scan rates. In their absorbance and emission spectra, all of the compounds, except MFPQ, exhibit large Stokes shifts, which are related to the rearrangement of the excited-state and also to solvent effects. ECL was observed for MAPQ, CFPQ, and CFPP in MeCN/benzene solutions that generally agree with the photoluminescence spectra, suggesting that the energy of annihilation is sufficient to form singlet excited states (the S-route). The ECL of MAPQ was strong enough to be seen with the naked eye. MFPQ did not produce ECL, probably because of the instability of the radical cation.
COLD IN-PLACE RECYCLING WITH EXPANDED ASPHALT MIX (CIREAM) (2014)

Cold in-place recycling with expanded asphalt mix (CIREAM) has become an accepted road rehabilitation technique in Ontario and other parts of the world given its advantages over regular cold in-place recycling (CIR) and other methods.Although CIREAM offers early strength advantages and extended paving periods among other benefits, late season CIREAM can be burdened by distresses such as ravelling, potholing and other moisture-induced damage.Limited information on the behaviour and failure mechanisms of CIREAM has also hindered its utilization in spite of the numerous benefits.This research investigated effects of additives on the foam properties of roofing asphalt flux (RAF) binder in order to evaluate the suitability of the binder for CIREAM.The study also investigated how mixture variables and test protocols affect performance properties that relate to early strength and moisture resistance of CIREAM versus CIR.Indirect tensile strength testing with moisture conditioning was used to assess the effects of asphalt cement type (80, 300 pen grades and polymer modified asphalt), conditioning time, and additives such as Portland cement, foam stabilizers, polymers and fibers.Uniaxial cyclic compression with partial confinement was used to assess effect of additives on deformation resistance of recycled mixes.Although a siloxane-based stabilizer significantly improved the stability of RAF foam, the binder may not be suitable for CIREAM due to its limited expansion.The optimum binder content was found to be around 2 percent, which is significantly higher than the minimum 1 percent currently used in Ontario.Both Portland cement and the siloxane additive exerted significant positive effects on strength behaviour and moisture resistance of the recycled mixes.In regular CIR mixes, 2 percent binder content gave desirable early strength and strain performance compared to 1 percent.
Helical-mode magnetostatic resonances in small ferrite particles and singular metamaterials (2010)

Small ferrite-disk particles with magnetostatic (magneto-dipole) oscillations are characterized by the topological-phase states-the vortex states. In a recently published paper (Kamenetskii et al 2010 Phys. Rev. A 81 053823), it was shown that such magnetic vortices act as traps, providing purely subwavelength confinement of electromagnetic fields. The symmetry properties of magnetostatic-vortex ferrite disks allow one to propose new-type subwavelength microwave structures. In this paper it is demonstrated that the unique topological properties of the fields in a ferrite disk are intimately related to the symmetry breaking effects of magnetostatic oscillations. This analysis is based on postulates about a physical meaning of the magnetostatic-potential function ψ(r, t) as a complex scalar wavefunction, which presumes a long-range phase coherence in magnetic dipole-dipole interactions. The proper solutions are found based on an analysis of magnetostatic-wave propagation in a helical coordinate system. It is shown that while a composition of two helical waves may acquire a geometrical phase over-running of 2π during a period, every separate helical wave has a dynamical phase over-running of π and so behaves as a double-valued function. This results in the appearance of helical-mode magnetostatic resonances in quasi-2D ferrite disks. The solutions give magnetostatic-wave power-flow-density vortices with cores at the disk center and azimuthally running waves of magnetization. The near fields of magnetostatic-vortex ferrite-disk particles are characterized by space-time symmetry violation. For incident electromagnetic waves, such particles, with sizes much less than the free-space electromagnetic wavelength, appear as local singular regions. From the properties of a composition of magnetostatic-vortex ferrite-disk particles, one may propose novel metamaterials-singular metamaterials.
