The Effect Of Direct Yaw Moment On Human Controlled Vehicle Systems (2010)

Advances in computing technology have had a profound impact on the design and development of modern vehicle systems. These advances have provided the basis for virtual design and testing in simulated environments, as well as the development of active control systems capable of providing improved vehicle safety, efficiency, and performance. Continued developments in hybrid powertrains and on-board computing will provide for greater amounts of control, through the integration of larger numbers of actuators and more complex control schemes. The intention of this research is to investigate the effects of advanced vehicle dynamics controls on the human operated vehicle system. Hybrid electric vehicle systems incorporating multiple electric drive motors are capable of actively distributing drive and braking torque to the individual wheels of the vehicle. The modulation of these torques can be used to optimize or alter the dynamic response of the vehicle, through the application of a direct yaw moment. A control structure capable of determining and dynamically allocating appropriate control signals for over-actuated vehicle systems is proposed. A dynamic simulation of a virtual prototype BMW 330i is utilized to evaluate the effects of active drive torque vectoring on vehicle response. The effects of the proposed system on the human operator are also evaluated, through the use of driver model in-the-loop simulations. The results presented indicate the promising potential of direct yaw moment control in modulating the response of human operated vehicle systems. The interactions between the human driver model and control systems were shown to be favourable. The scientific contributions and implications of the research are detailed, including application of closed-loop simulation to engineering education. Conclusions on the efficacy of developed models, methodologies and systems are given. Finally, recommendations on potential improvements and future research regarding vehicle modelling and motion control are provided.
R‐spondin1 synergizes with Wnt3A in inducing osteoblast differentiation and osteoprotegerin expression (2008)

R-spondins are a new group of Wnt/beta-catenin signaling agonists, however, the role of these proteins in bone remains unclear. We reported herein that R-sponin1 (Rspo1) acted synergistically with Wnt3A to activate Wnt/beta-catenin signaling in the uncommitted mesenchymal C2C12 cells. Furthermore, we found that Rspo1 at concentrations as low as 10 ng/ml synergized strongly with Wnt3A to induce C2C12 osteoblastic differentiation and osteoprotegerin expression. These events were blocked by Wnt/beta-catenin signaling antagonist Dickkopf-1. Finally, we demonstrated that Rspo1 synergized with Wnt3A to induce primary mouse osteoblast differentiation. Together, these findings suggest that Rpos1 may play an important role in bone remodeling.
“Marketing” retail service quality with respect to supermarket in Mysore city (2012)

Retail stores belong to service industry, which offer a hybrid of goods and service, thus retail product management not only have the common characters of goods quality but also have the special characters of services quality. This research analyzes the Service Quality of the Organized Retail Store that contributes to the customer satisfaction in Mysore city. The research was carried out at MORE (future groups) supermarket; Mysore The objective of the study was to determine the effect of service quality on customer satisfaction. Retail Service quality can be measured by taking five dimensions such as Physical aspect, Reliability, Personal Interaction, trustworthiness and Policy aspects. The data was collected through the structure questionnaire by using Likert scale and SPSS was used to analyses the data. The result revealed that all the dimensions have a significant effect on customer satisfaction.
Isolation of Escherichia coli from piglets in South Korea with diarrhea and characteristics of the virulence genes. (2010)

Escherichia coli was isolated from the feces of 122 piglets with diarrhea on 55 farms in Korea. The virulence genes of each isolate were characterized by polymerase chain reaction (PCR). Of the 562 isolates, 191 carried 1 or more of the virulence genes tested for in this study. Of the 191 isolates, 114 (60%) carried 1 or more of the genes for enterotoxigenic E. coli (ETEC) fimbriae F4, F5, F6, F18, and F41 and ETEC toxins LT, STa, and STb, 57 (30%) carried 1 or more of the genes for the Shiga-toxin-producing E. coli (STEC) toxins Stx1, Stx2, and Stx2e, and 21% and 37% carried the gene for enteropathogenic E. coli intimin and for enteroaggregative E. coli toxin, respectively. Collectively, our results indicate that other pathotypes of E. coli as well as ETEC can be strongly associated with diarrhea in piglets. In addition, detection of the genes for Stx1 and Stx2 indicates that pigs are reservoirs of human pathogenic STEC.
Inhibition by ricin of protein synthesis <i>in vitro</i>. Ribosomes as the target of the toxin (1973)

1. Ricin (a toxic protein from the seeds of Ricinus communis) is a powerful inhibitor of the poly(U)-directed incorporation of phenylalanine into polypeptides catalysed by isolated rat liver ribosomes and elongation factors 1 and 2 (EF 1 and EF 2). The inhibition can be largely overcome by increasing the concentration of ribosomes. 2. The toxin does not affect the binding of phenylalanyl-tRNA to ribosomes catalysed by EF 1, nor does it inhibit the puromycin reaction used as a test for peptide-bond formation catalysed by ribosomes. 3. Ricin inhibits the ribosome-linked GTP hydrolysis catalysed by EF 2. 4. Ribosomes treated with ricin and washed through sucrose gradients containing 0.6m-NH(4)Cl are functionally inactive in those assay systems that are sensitive to the presence of added toxin. 5. It is suggested that ricin brings about an irreversible modification of ribosomes which impairs their ability to interact with EF 2. Since ricin inhibits at a molar concentration much lower than that of ribosomes it probably acts catalytically. No added cofactor is necessary for the inhibitory action of the toxin.
Identification of the hydrophobic glycoproteins of Caenorhabditis elegans (2005)

Hydrophobic proteins such as integral membrane proteins are difficult to separate, and therefore to study, at a proteomics level. However, the Asn-linked (N-linked) carbohydrates (N-glycans) contained in membrane glycoproteins are important in differentiation, embryogenesis, inflammation, cancer and metastasis, and other vital cellular processes. Thus, the identification of these proteins and their sites of glycosylation in a well-characterized model organism is the first step toward understanding the mechanisms by which N-glycans and their associated proteins function in vivo. In this report, a proteomics method recently developed by our group was applied to identify 117 hydrophobic N-glycosylated proteins of Caenorhabditis elegans extracts by analysis of 195 glycopeptides containing 199 Asn-linked oligosaccharides. Most of the proteins identified are involved in cell adhesion, metabolism, or the transport of small molecules. In addition, there are 18 proteins for which no function is known or predictable by sequence homologies and two proteins which were previously predicted to exist only on the basis of genomic sequences in the C. elegans database. Because N-glycosylation is initiated in the lumen of the endoplasmic reticulum (ER), our data can be used to reassess the previously predicted subcellular localizations of these proteins. As well, the identification of N-glycosylation sites helps establish the membrane topology of the associated glycoproteins. Caenorhabditis elegans strains are presently available with mutations in 17 of the genes we have identified. The powerful genetic tools available for C. elegans can be used to make other strains with mutations in genes encoding N-glycosylated proteins and thereby determine N-glycan function.
Evaluation of Pressure Bed Sensor for Automatic SAHS Screening (2014)

We evaluate the performance of an unobtrusive sleep monitoring system in the detection of the sleep apnea- hypopnea syndrome (SAHS). The proposed system is a pressure bed sensor (PBS) that incorporates multiple pressure sensors into a bed mattress to measure several physiological signals of the sleeping subject: respiration; heart rate; and body movements. An automatic algorithm is developed to calculate a respiratory event index (REI). The recordings of 24 patients with suspected sleep problems are analyzed, and the results are compared with the gold standard methods; first with manual scoring of polysomnography to calculate the apnea-hypopnea index (AHI), and second with automatic detection of REI from the respiratory inductive plethysmography belts. The correlation coefficient between AHI and REI from PBS is up to 0.93. Evaluating the ability of PBS in the diagnosis of pathologic (AHI ≥ 5) and nonpathologic (AHI <; 5) subjects, we obtained a sensitivity, specificity, and accuracy of 100%, 92%, and 96%, respectively. To diagnose three levels of SAHS, mild, moderate, and severe, the Cohen's kappa value is 0.76. These findings support that PBS recording could provide a simple and unobtrusive method for detection of SAHS in home monitoring.
A dipole antenna coupled electromagnetically to a two-wire transmission line (1959)

The properties of a dipole antenna coupled electromagnetically to a two-wire transmission line are studied experimentally. It is found that the coupling of the antenna to the transmission line can be maximized by a proper choice of 1) the angular position of the antenna with respect to the transmission line, 2) the length of the antenna, and 3) the separation of the antenna from the transmission line. The effect of the spacing between the wires of the transmission line on the optimum parameters is investigated. It is found that the optimum angular position of the antenna is not noticeably altered if, instead of a single antenna, an array of properly located antennas is used as the load. The advantage of an antenna array built on this coupling principle is discussed.
Acetyl CoA Carboxylase: Isolation and Characterization of Native Biotin Carboxyl Carrier Protein (1971)

A large form of biotin carboxyl carrier protein (BCCP(L)) has been isolated from extracts of Escherichia coli. It has a minimal molecular weight of 20,000, according to its behavior on sodium dodecylsulfate-polyacrylamide gel electrophoresis, and contains approximately 1 mol of biotin per 22,000 g of protein. BCCP(L) exhibits K(m) values, in the biotin carboxylase and transcarboxylase half-reactions of acetyl CoA carboxylase, of 2 x 10(-7) M and 4 x 10(-7) M, respectively; these values are 50-100 times lower than those obtained with smaller forms of BCCP previously isolated. Electrophoresis of crude extracts of E. coli indicates that the major biotin-containing protein migrates at the same rate as BCCP(L), which suggests that BCCP(L) is the native form of BCCP in E. coli.
The adaptation of bhk cells to a non-ammoniagenic glutamate-based culture medium (1999)

Although glutamine is a major carbon source for mammalian cells in culture, its chemical decomposition or cellular metabolism leads to an undesirable excess of ammonia. This limits the shelf-life of glutamine-supplemented media and may reduce the cell yield under certain conditions. We have attempted to develop a less ammoniagenic medium for the growth of BHK-21 cells by a mole-to-mole substitution of glutamine by glutamate. This results in a medium that is thermally stable but unable to support an equivalent growth yield. However, supplementation of the glutamate-based medium with asparagine (3 mM) and a minimal level of glutamine (0.5 mM) restored the original growth capacity of the cultures. Substitution of the low level of glutamine with the glutamine dipeptides, ala-gln (1 mM), or gly-gln (3 mM) resulted in an equivalent cell yield and in a thermally stable medium. The ammonia accumulation in cultures with glutamate-based medium was reduced significantly (>60%). Factors mediating growth and adaptation in medium substituted with glutamate were also investigated. The maximum growth capacity of the BHK-21 cells in glutamate-based medium (without glutamine) was achieved after a period of adaptation of 5 culture passages from growth in glutamine-based cultures. Adaptation was not influenced by increases in glutamate uptake which was constitutively high in BHK cells. Adaptation was associated with changes in the activities of enzymes involved in glutamate or glutamine metabolism. The activities of glutamine synthetase (GS) and alanine aminotransferase (ALT) increased significantly and the activity of phosphate-activated glutaminase (PAG) decreased significantly. The activity of glutamate dehydrogenase (GDH) showed no significant change after adaptation to glutamate. These changes resulted in an altered metabolic profile which included a reduced ammonia production but an increased alanine production. Alanine production is suspected of being an alternative route for removal of excess nitrogen.

Linear, high-speed, high-power strained quantum-well LEDs (1992)

InGaAs/AlGaAs edge-emitting LEDs are shown to be efficient (4% quantum efficiency), linear over four decades of current, and capable of operating in a analog or digital mode at modulation bandwidths exceeding 500 MHz. The spectral width of these LEDs is on the order of 700 AA at the 3-dB intensity points. The device is suited for high-speed backplane and short-distance local area network applications, where fiber dispersion is inconsequential. It appears to be a competitive optical power source for a variety of advanced applications, with speed and power outputs approaching those of laser diodes, but without the complication of a threshold current and associated active stabilization circuitry.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">></ETX>
Vulcanization: Conventional and Dynamic (1995)

Abstract Conventional vulcanization, has a history of over 150 years, during which there have been increasing needs for technology to permit more and more rapid processing before the vulcanization of a rubber article in its final shape. But, at the same time, one desired increased rates of crosslinking after the part was in its final shape, e.g. , in a mold. These two objectives are opposed to one another. For fast processing, we would like to increase temperatures to reduce the resistance to flow; but we do not want vulcanization to occur before processing flow is complete. On the other hand, after a rubber article is in its final shape or form, we would like for vulcanization to occur as rapidly as possible. The reasons for these objectives, are to increase capital utilization and to reduce the cost of money. The use of the premature vulcanization inhibitor, CTP, can give improved processing safety without loss of vulcanization throughput. In the case of thermoplastic elastomers prepared by dynamic vulcanization, all of the vulcanization is done rapidly during mixing, before the rubber compound flows into its final shape, e.g. , during rapid thermoplastic injection molding (in seconds, not minutes). The dynamic vulcanization process does add cost to the material; however, this is more than offset by the gains in capital utilization. I would be remiss if I did not mention some potential disadvantages associated with the thermoplastic elastomers. One of these is that, at temperatures above the temperatures of flow, there is a great reduction in the usefulness of the properties (the materials can melt). A related disadvantage is that resistance to permanent set at high temperatures may be inadequate. However, the elevated-temperature set resistance of thermoplastic elastomers prepared by dynamic vulcanization is generally better than that of those prepared by other means. Both kinds of vulcanization are important and may continue to be so for another 150, or so, years.
Synthesis and Polymerization of Substituted Ammonium Sulfonate Monomers for Advanced Materials Applications (2011)

Sulfonated polymers have found use as ion-exchange membranes for use in fuel cells, water purification, electroactive devices, and inorganic materials templating and synthesis. Improving the materials for these applications and opening up new applications requires the ability to synthesis targeted or more complex sulfonated polymers, which includes tailoring the chemistry (copolymerization across a wider range of solubility) and/or polymer architecture (block, graft, nanoparticle). This article will summarize the recent work using sulfonated monomers with substituted ammonium counterions as a versatile route for enabling this goal. Two main benefits of these monomers are as follows. First, they are useful for preparing amphiphilic copolymers, which is a challenge using traditional acidic or alkali salt forms of sulfonated monomers. Second, sulfonated polymers with substituted ammonium counterions are useful polymers for obtaining unique material properties, such as organo-gelation of low polarity solvents or obtaining ionic liquid polymers for the fabrication of solid polymer electrolytes.

Cloning and sequence analysis of a human type A/B hnRNP protein (1991)

A cDNA encoding a 284 residue long type A/B hnRNP protein has been cloned. This protein, previously referred to as type C [(1987) J. Biol. Chem. 262, 17126-17137], is an RNA unwinding protein from HeLa 40S hnRNP with a high affinity for G- followed by U-rich sequences. The N-terminal part of the protein contains two consensus RNA binding domains present in a number of other RNA binding proteins. The C-terminal part is glycine-rich and contains a potential ATP/GTP binding loop. The distribution of charged amino acids is highly uneven and there are multiple potential phosphorylation sites.
Trans fatty acids promote the growth of some Lactobacillus strains (2006)

Five Lactobacillus strains (2 L. gasseri, 2 L. plantarum and 1 L. reuteri) were cultured in modified MRS medium containing fatty acids (FAs) instead of Tween 80 for 24 h at 37 degrees C, to learn the effect of saturated and unsaturated FAs on the Lactobacillus growth. Free FAs included palmitic (16:0), palmitoleic (c9-16:1), stearic (18:0), oleic (c9-18:1), elaidic (t9-18:1), cis-vaccenic (c11-18:1), vaccenic (t11-18:1), linoleic (c9, c12-18:2), conjugated linoleic (c9, t11- and t10, c12-18:2), alpha-linolenic (c9, c12, c15-18:3), alpha-eleostearic (c9, t11, t13-18:3), eicosapentaenoic (20:5), and docosahexaenoic (22:6) acids. Among free FAs, oleic acid stimulated the growth of all Lactobacillus strains, whereas palmitoleic acid had almost no affect on the Lactobacillus growth. Saturated FAs such as stearic and palmitic acids inhibited or did not affect the Lactobacillus growth. Polyunsaturated FAs such as alpha-linolenic, eicosapentaenoic and docosahexaenoic acids strongly inhibited the Lactobacillus growth at 7.6 x 10(-4) m. Octadecenoic acids such as oleic, elaidic, cis-vaccenic and vaccenic acids remarkably promoted the growth of L. gasseri, regardless of the different double bond positions and configurations. When oleic or cis-vaccenic acid was incubated with L. gasseri, the FAs was transformed to cyclopropane FAs (methyleneoctadecanoic acids) after incorporation into the cells. On the other hand, trans FAs such as elaidic and vaccenic acids incorporated into the cells were not converted to another FAs. Conjugated linoleic and alpha-eleostearic acids having a trans double bond promoted the Lactobacillus growth. The growth of L. gasseri was also stimulated by trans-rich free FAs from hydrogenated canola and fish oils. These results showed that octadecenoic acid and trans FAs had strong promotion activities for the Lactobacillus growth due to their incorporation into membrane lipids.

Loss minimization in scalar-controlled induction motor drives (IMD) with search controllers (SC) is investigated. The problems arising when the input power is used as the controlled variable are described. It is proved that better results are achieved if the stator current is used as the controlled variable.
Static and dynamic evanescent wave light scattering studies of diblock copolymers adsorbed at the air/water interface (1993)

We report the results of static and dynamic evanescent wave light scattering studies of a monolayer of a diblock copolymer, polystyrene-b-polymethylmethacrylate (PS-b-PMMA) with weight averaged molecular weights (Mw) of 880 000:290 000 supported at the air/water interface. Our studies probe the interfacial structural and dynamic properties of the monolayer on a length scale which is a fraction of the wavelength of light. The static light scattering studies were carried out as a function of polymer surface coverage and temperature; we also report some preliminary data for the dependence of the static structure function on the relative molecular weights of the PS and PMMA blocks. The complementary dynamic light scattering studies were carried out only as a function of surface coverage. Our data suggest that, upon spreading in the air/water interface, PS-b-PMMA (880:290 K) copolymers form thin disklike aggregates containing about 240 molecules. These data are consistent with a model in which each such aggregate is a ‘‘furry disk’’ with a dense core consisting of a layer of collapsed PS blocks atop a thin layer of extended PMMA blocks on the water surface and a brushlike boundary of extended PMMA blocks. The data show that the furry disks diffuse freely when the surface coverage is small, but when the surface coverage is large, they are immobile. Our data also suggest that the furry disks can aggregate to form even larger ‘‘islands’’ of disks with an extension greater than 20 μm. The static structure function of the assembly of furry disks is well described, over a wide range of surface coverage, by the structure factor of a two-dimensional hard disk fluid modulated by a two-dimensional hard disk form factor.
Color enhancement of TV picture using RGB sensor (1996)

An object color can be seen differently under different ambient illumination, but the human visual system has color constancy with which the object color can be perceived constantly. When TV is watched under a certain outer illumination, the color on the CPT is somewhat distorted due to the emitting spectrum of outer illumination. In this paper, we suggest both intensity decision and illumination decision functions to consider the influence of illumination. Based on these functions, the color enhancement algorithm in a TV using an RGB sensor is also proposed. The TV of the proposed algorithm has better visual quality for the view point of the human visual system and reproduces enhanced color compared to conventional TV.
