Variable Shift Schedule Control for Integrated Starter Generator Equipped Hybrid Vehicles (2001)

<div class="htmlview paragraph">In this study, conducted during 42V product development by Visteon, a Variable Shift Schedule<span class="xref"><sup>1</sup></span> (VSS) control strategy was designed and tested on a vehicle equipped with an Integrated Starter Generator (ISG) and a step ratio automatic transmission. The strategy incorporates two ratio change points (a high point and a low point) for a given vehicle speed and driver demand torque (measured by throttle position). By evaluating battery state of charge (SOC) and torque boost available from the electric drive system, the strategy can interpolate the earliest point for a change in ratio. It can also choose to “lock” the torque converter elements within the automatic transmission (AT) while continuing to provide consistent vehicle performance. The result is the ability to operate the internal combustion (IC) engine in a range of greater efficiency during the up-shift sequence. In addition the automatic transmission is able to remain in higher ratio ranges for extended durations. This effectively creates a vehicle that operates at levels of greater fuel efficiency and lower emissions. Computer Aided Engineering (CAE) modeling experiments are carried out to prove the validity of the proposed transmission control strategy and support the claims.</div>
Methylated Trivalent Arsenic Species Are Genotoxic (2001)

The reactivities of methyloxoarsine (MAs(III)) and iododimethylarsine (DMAs(III)), two methylated trivalent arsenicals, toward supercoiled phiX174 RFI DNA were assessed using a DNA nicking assay. The induction of DNA damage by these compounds in vitro in human peripheral lymphocytes was assessed using a single-cell gel (SCG, "comet") assay. Both methylated trivalent arsenicals were able to nick and/or completely degrade phiX174 DNA in vitro in 2 h incubations at 37 degrees C (pH 7.4) depending on concentration. MAs(III) was effective at nicking phiX174 DNA at 30 mM; however, at 150 microM DMAs(III), nicking could be observed. Exposure of phiX174 DNA to sodium arsenite (iAs(III); from 1 nM up to 300 mM), sodium arsenate (from 1 microM to 1 M), and the pentavalent arsenicals, monomethylarsonic acid (from 1 microM to 3 M) and dimethylarsinic acid (from 0.1 to 300 mM), did not nick or degrade phiX174 DNA under these conditions. In the SCG assay in human lymphocytes, methylated trivalent arsenicals were much more potent than any other arsenicals that were tested. On the basis of the slopes of the concentration-response curve for the tail moment in the SCG assay, MAs(III) and DMAs(III) were 77 and 386 times more potent than iAs(III), respectively. Because methylated trivalent arsenicals were the only arsenic compounds that were observed to damage naked DNA and required no exogenously added enzymatic or chemical activation systems, they are considered here to be direct-acting forms of arsenic that are genotoxic, though they are not, necessarily, the only genotoxic species of arsenic that could exist.
Normative Social Influence is Underdetected (2008)

The present research investigated the persuasive impact and detectability of normative social influence. The first study surveyed 810 Californians about energy conservation and found that descriptive normative beliefs were more predictive of behavior than were other relevant beliefs, even though respondents rated such norms as least important in their conservation decisions. Study 2, a field experiment, showed that normative social influence produced the greatest change in behavior compared to information highlighting other reasons to conserve, even though respondents rated the normative information as least motivating. Results show that normative messages can be a powerful lever of persuasion but that their influence is underdetected.
Telomere Length Is a Determinant of Emphysema Susceptibility (2011)

Our data indicate that short telomeres lower the threshold of cigarette smoke-induced damage, and implicate telomere length as a genetic susceptibility factor in emphysema, potentially contributing to its age-related onset in humans.
Improving the energy product of hard magnetic materials (2002)

A route toward enhancing the energy product $(\mathrm{BH}{)}_{\mathrm{max}}$ of permanent magnetic materials, at room temperature, based on ferromagnetic-(FM-) antiferromagnetic (AFM) exchange interactions has been developed. The exchange coupling, which is induced by ball milling hard magnetic ${\mathrm{SmCo}}_{5}$ with AFM NiO powders, results in an enhancement of coercivity ${H}_{C}$ and squareness ratio ${M}_{R}{/M}_{S}$ (remnant-saturation magnetizations), which depends on the FM:AFM ratio and the processing conditions. However, the presence of the AFM in the composite results also in a competing effect, i.e., reduction of the overall saturation magnetization, which decreases $(\mathrm{BH}{)}_{\mathrm{max}}.$ Nevertheless, it has been found that after an optimization of the FM:AFM ratio and the milling conditions it is possible to achieve an improvement of $(\mathrm{BH}{)}_{\mathrm{max}}.$

Electrically driven high-Q quantum dot-micropillar cavities (2008)

We report on electrically pumped high-Q quantum dot-micropillar cavities with quality factors of up to 16.000. A special current injection scheme using a ring-shaped upper contact is presented which ensures an efficient light out-coupling through the uncapped upper surface of the micropillar. The devices feature excellent single-quantum dot cavity quantum electrodynamic effects with a Purcell enhancement of about 10 for a micropillar with a diameter of 2.5μm.
Antitumor Activity of Gold(I), Silver(I) and Copper(I) ComplexesContaining Chiral Tertiary Phosphines (1998)

The in vitro cytotoxicities of a number of gold(I), silver(I) and copper(I) complexes containing chiral tertiary phosphine ligands have been examined against the mouse tumour cell lines P815 mastocytoma, B16 melanoma [gold(I) and silver(I) compounds] and P388 leukaemia [gold(I) complexes only] with many of the complexes having IC(50) values comparable to that of the reference compounds cis-diamminedichloroplatinum(ll), cisplatin, and bis[1,2-bis(diphenylphosphino) ethane]gold(I) iodide. The chiral tertiary phosphine ligands used in this study include (R)-(2-aminophenyl)methylphenylphosphine; (R,R)-, (S,S)- and (R(*),R(*))-1,2-phenylenebis(methylphenylphosphine); and (R,R)-, (S,S)- and (R(*),R(*))-bis{(2-diphenylphosphinoethyl)phenylphosphino}ethane. The in vitro cytotoxicities of gold(I) and silver(I) complexes containing the optically active forms of the tetra(tertiary phosphine) have also been examined against the human ovarian carcinoma cell lines 41M and CH1, and the cisplatin resistant 41McisR, CH1cisR and SKOV-3 tumour models. IC(50) values in the range 0.01 - 0.04 muM were determined for the most active compounds, silver(I) complexes of the tetra(tertiary phosphine). Furthermore, the chirality of the ligand appeared to have little effect on the overall activity of the complexes: similar IC(50) data were obtained for complexes of a particular metal ion with each of the stereoisomeric forms of a specific ligand.
Modeling the roles of oxygen vacancies in thin film ferroelectric memory (2002)

The role of oxygen vacancies in thin ferroelectric film is modeled and the corresponding ferroelectric properties are numerically simulated using Ising Model. The octahedral cage of a perovskite cell is distorted in the presence of oxygen vacancy. Thus the originally symmetric potential for the titanium ion is now asymmetric due to the distortion. In the Monte Carlo simulation, the Hamiltonian of the dipole system is modified by this distorted potential. The latter also affects the probability of the flipping a dipole as well as the coupling between the neighboring dipoles. These oxygen vacancies are modeled to be randomly distributed at the electrode/film interfaces. Experimental results in frequency response, amplitude dependence, fatigue and distorted hysteresis loops are numerically reproduced.

Evidence for chemical bond formation between surface treated carbon fibres and high temperature thermoplastics (1994)

Abstract The interaction between surface‐treated carbon fibres and high temperature thermoplastics (polyethersulfone and polycarbonate) was studied by measuring the interlaminar shear strength of unidirectionally reinforced composites with a fibre volume content of 60%. The ILSS‐values were correlated with the surface concentration of the acidic functional groups of the carbon fibres, as analysed by temperature programmed desorption and contact angle measurements using basic aqueous solutions (pH ≥ 12). Linear relationships were found with both the amount of carbon dioxide desorbed by decomposition of carboxylic surface groups and the work of adhesion calculated from the measured contact angles. This result could be interpreted as a consequence of acid–base interactions with the basic polymers. However, strongly acidic carboxylic groups are decomposed during processing of the composites. Therefore, the high ILSS‐values can only be explained by chemical bonds being formed with the functional groups of the polymers during decomposition of the carboxylic surface groups. © 1994 John Wiley & Sons, Inc.
FUEL CONSUMPTION AND EMISSION TESTING OF AN ENGINE OIL ADDITIVE CONTAINING PTFE COLLOIDS (1981)

Comparative fuel consumption tests have been carried out on an engine using a straight grade SAE 30 engine oil and the same engine oil with 40 gms/l of a ptfe colloid added to it. On a typical city driving schedule, fuel consumption decreased by an average of about 6.4 per cent and on a highway driving cycle by about 3.5 per cent. Steady state tests in the idling to 2000 rpm range showed results consistent with the city schedule. Emission measurements showed no change due to the additive. Sufficient results were taken on the city schedule to show a strong statistical significance for the improved fuel economy. (Author/TRRL)
A Genomic Screening Approach to the Structure‐Guided Identification of Drug Candidates from Natural Sources (2007)

The potential of actinomycetes to produce natural products has been exploited for decades. Recent genomic sequence analyses have revealed a previously unrecognized biosynthetic potential and diversity. In order to rationally exploit this potential, we have developed a sequence-guided genetic screening strategy. In this "genome mining" approach, genes that encode tailoring enzymes from natural product biosyntheses pathways serve as indicator genes for the identification of strains that have the genetic potential to produce natural products of interest. We chose halogenases, which are known to be involved in the synthesis of halometabolites as representative examples. From PCR screening of 550 randomly selected actinomycetes strains, we identified 103 novel putative halogenase genes. A phylogenetic analysis of the corresponding putative halogenases, and the determination of their sequential context with mass spectrometric analysis of cultures filtrates revealed a distinct correlation between the sequence and secondary metabolite class of the halometabolite. The described screening strategy allows rapid access to novel natural products with predetermined structural properties.
Architectural proteins, transcription, and the three‐dimensional organization of the genome (2015)

Architectural proteins mediate interactions between distant sequences in the genome. Two well-characterized functions of architectural protein interactions include the tethering of enhancers to promoters and bringing together Polycomb-containing sites to facilitate silencing. The nature of which sequences interact genome-wide appears to be determined by the orientation of the architectural protein binding sites as well as the number and identity of architectural proteins present. Ultimately, long range chromatin interactions result in the formation of loops within the chromatin fiber. In this review, we discuss data suggesting that architectural proteins mediate long range chromatin interactions that both facilitate and hinder neighboring interactions, compartmentalizing the genome into regions of highly interacting chromatin domains.
How to wring a table dry: entropy compression of relations and querying of compressed relations (2006)

We present a method to compress relations close to their entropy while still allowing efficient queries. Column values are encoded into variable length codes to exploit skew in their frequencies. The codes in each tuple are concatenated and the resulting tuplecodes are sorted and delta-coded to exploit the lack of ordering in a relation. Correlation is exploited either by co-coding correlated columns, or by using a sort order that leverages the correlation. We prove that this method leads to near-optimal compression (within 4.3 bits/tuple of entropy), and in practice, we obtain up to a 40 fold compression ratio on vertical partitions tuned for TPC-H queries.We also describe initial investigations into efficient querying over compressed data. We present a novel Huffman coding scheme, called segregated coding, that allows range and equality predicates on compressed data, without accessing the full dictionary. We also exploit the delta coding to speed up scans, by reusing computations performed on nearly identical records. Initial results from a prototype suggest that with these optimizations, we can efficiently scan, tokenize and apply predicates on compressed relations.
Injection Molding of 17-4 PH Stainless Steel (1984)

<div class="htmlview paragraph">17-4 PH stainless steel has been successfully formed by powder metallurgy (P/M) injection molding. Injection molding is a relatively new P/M technique. In this process, metal powder is mixed with a plastic binder, and the part shape is injection molded as in plastics fabrication practice. The binder is extracted, and the part is sintered to 95-96% of full density.</div> <div class="htmlview paragraph">Sintering atmospheres and temperature profiles for optimized material properties were developed. Material mechanical properties were evaluated by tensile, impact, and fatigue tests. Five prototype fin bases for a missile were fabricated. The effect of Hot Isostatic Pressing was determined. The mechanical properties compare favorably to those of investment cast or wrought 17-4 PH steel.</div>
Articular cartilage matrix and structure: a minireview. (1991)

The ability of articular cartilage to undergo reversible deformation is dependent upon the organization of specific macromolecules within the extracellular matrix. This abundant matrix is elaborated by a small number of chondrocytes which maintain homeostasis via a synchronized balance between anabolism and catabolism. Type II collagen together with smaller amounts of other collagens form the fibrous network of the tissue in which are "entrapped" the aggregating proteoglycans in an underhydrated form. Small amounts of nonaggregating dermatan sulfate containing proteoglycans and matrix proteins are also present in the matrix but their function is less well understood.
Integration of remote sensing, meteorological and physiographic data for the delimitation of agrometeorological homogeneous zones (2002)

The regionalization of agrometeorological parameters such as the air temperature, for a given region is limited by the meteorological network system. The Quebec meteorological network does not adequately satisfy the needs of the agro-food industry of the province. The number of stations is insufficient and some stations need to be resited to meet the needs of farmers. Interpolation of data collected at each station has always been used. Results thus obtained are not representative of real meteorological conditions. The authors have to recommend an other approach to increase the spatial resolution of the actual agrometeorological network. The integration of physiographical, agricultural and satellite data has allowed the identification of homogeneous agrometeorological zones. Each zone can have a better optimization and spatialization of agrometeorological data measured by the network. The regionalization of the air temperature at the stations in each zone is then possible.
Phototactic Responses to Ultraviolet and White Light in Various Species of Collembola, Including the Eyeless Species,<i>Folsomia candida</i> (2007)

Previous observations have indicated homology in the cellular components between Collembolan eyes and the compound eyes of insects. However, behavioral or physiological studies indicating similarities in function are lacking. Collembolan eyes were examined from three species in the Family Isotomidae using scanning electron microscopy. Collembolan eyes are arranged dorsally and laterally on each side of the head in two species, Proisotoma minuta with eight eyes on each side of the head and Folsomia similis with one eye on each side of the head. In both of these species the eyes were located just posterior to the postantennal organ. In Folsomia candida, no external eye structures were detected. These three species were assayed for a series of behavioral preferences using ultraviolet (UV), white light and dark, and temperature conditions. The tests demonstrated that over 76% of all three species, including the eyeless F. Candida, chose white over UV light, over 69% preferred dark over UV, and over 77% favored dark over white light. The results demonstrated that all three species detect both UV and white light and avoid it, preferring cool, dark habitats. From the results of this study, it is hypothesized that F. candida may, in fact, be only "lensless" and may be able to detect light by having internal, non-ocular photoreceptors. Further histological studies are needed to investigate this possibility.
Barrier Properties of Coated and Laminated Polyolefin Films for Food Packaging (2010)

The food packaging industry demands polymer films possessing a defined barrier against permeation of gases, moisture and flavor. The objective of this study was to assess the differences between the barrier properties of coated and un-coated polyolefine films. Eight types of packaging films are prepared by standard industrial procedure by cast film extrusion processing with chill rollers: biaxially oriented polypropylene (BOPP), BOPP coated by acrylic copolymer, metallized BOPP by aluminum, and low-density polyethylene (LDPE). The influence of lamination and metallization on the gas molecules (CO2, O2 and N2) was determined by Lyssy's method. The moisture transparency was assessed according to the gravimetric method. The substantial differences between the barrier properties of the coated and un-coated films were estimated. It was estimated that the lamination process improves the oxygen barrier but not necessarily the moisture barrier, due to the different mechanisms for oxygen and moisture permeability. The obtained barrier properties data were considered from a practical point of view. It was concluded that films based on metallized BOPP has excellent barrier properties and can be used to over wrap food products.
Adaptive mean shift for target- tracking in FLIR imagery (2009)

In this paper, we present a novel adaptive mean-shift tracker for tracking moving targets in the FLIR imagery, captured from an airborne moving platform. First, each target's position is manually marked at the first frame to initialize the adaptive mean-shift based tracker. For each target, multiple different features are extracted from both the targets and background during tracking, and an on-line feature ranking method is deployed to adaptively select the most discriminative feature for the mean-shift iteration. In addition, to compensate the motion of the moving platform, a block matching method is applied to compute the motion vector, which will be used in the RANSAC algorithm to estimate the affine model for global motion. We test our method on the AMCOM FLIR data set, the results indicate that our Adaptive mean-shift tracker can track each target accurately and robustly.
An elevated serum level of transforming growth factor-beta 1 (TGF-beta 1) significantly correlated with lymph node metastasis and poor prognosis in patients with gastric carcinoma. (2001)

The serum level of TGF-beta 1 might be useful for predicting recurrence patterns and prognosis in patients with gastric carcinoma.
Compact Broadband Microstrip Antennas (2002)

Chapter 3 discusses compact broadband microstrip antenna designs. Design techniques for achieving broadband operation with a reduced antenna size are described. Related techniques include the use of a shorted patch with a thick air substrate, stacked shorted patches, chip-resistor loading, chip-resistor and chip-capacitor loading, and slot loading in the radiating patch or ground plane.
Morphological and Macromolecular Characterization of Hypocrea schweinitzii and Its Trichoderma Anamorph (1994)

Morphological, cultural, and isozyme analyses were used to determine variation in the Trichoderma anamorph of Hypocrea schweinitzii, a presumably unequivocal species of Trichoderma, and to assess whether the anamorph of H. schweinitzii can be assigned to T. longibrachiatum, T. reesei or T. pseudokoningii. The results of these studies indicate that H. schweinitzii comprises at least three distinct and taxonomically separable holomorph taxa that coincide with the geographical origin of the collections. The name H. schweinitzii can be applied to Northern Hemisphere and H. jecorina to tropical American collections; while taxonomically distinct, no name was given to a Chinese collection. The holomorphs of H. schweinitzii, H. jecorina, and the Chinese collection showed little intraspecific variation in morphology of the teleomorph or anamorph, or in cultural and isozyme characters. They exhibited no more variation than was noted in the ex type cultures of the named Trichoderma species. None of the named Trichoderma species coincided with any of the Hypocrea species studied. It is concluded that Trichoderma species in general can be narrowly defined but that morphology alone might not suffice to allow the identification of species. The synonymy of T. reesei under T. longibrachiatum is not supported by morphological and cultural observations and by isozyme data and it is therefore not accepted.
Interaction of glipizide and indoprofen. (1981)

The possible kinetic and dynamic interactions of indoprofen and glipizide were investigated in 6 healthy volunteers, taking indoprofen 200 mg t.i.d. for 7 days and a single dose of glipizide 5 mg before and during indoprofen medication. Series of blood samples were obtained for measurements of indoprofen, glipizide and glucose concentrations in blood. In addition urine concentrations of indoprofen were determined. The concentrations of indoprofen and glipizide were examined by HPLC and that of glucose enzymatically. Results suggest that indoprofen may reduce glipizide concentrations in plasma, but this does not seem to influence the blood glucose response to glipizide.
