Morphological study of cationic polymer–anionic surfactant complex precipitated in solution during the dilution process (2010)

We investigated the phase diagrams and the morphology of the complexes that were formed by cationic polymers, cationic cellulose (CC) and cationic dextran (CD), and by anionic surfactant-based sodium poly(oxyethylene) lauryl ether sulfate (LES). The anionic charge of the LES-based surfactants was changed by adding an amphoteric surfactant, lauryl amidopropyl betaine acetate (LPB), or a nonionic surfactant, polyoxyethylene stearyl ether (C18EO25). We discuss the relationship between the complex aggregation process and the morphology of the precipitated complexes. The morphologies of CC complex aggregates, which precipitated during the dilution process in a model shampoo solution, changed from membranous forms to mesh-like forms by decreasing the charges of both the CC and the surfactant. Their touch on hair in the rinsing process changed from sticky to smooth and velvety, corresponding to their rheological properties. In contrast, CD complex aggregates had a membranous form and a smooth touch independently of the charges on the polymer and surfactant. These results suggested that the control of the charges of both the polymer and surfactant and the choice of polymer structure are important for excellent conditioning effects upon rinsing with shampoo.
Islet Cell Antibody–Positive Versus –Negative Phenotypic Type 2 Diabetes in Youth (2009)

OBJECTIVE Using the clamp technique, youths with a clinical diagnosis of type 2 diabetes (CDx-type 2 diabetes) and positive pancreatic autoantibodies (Ab(+)) were shown to have severe impairment in insulin secretion and less insulin resistance than their peers with negative antibodies (Ab(-)). In this study, we investigated whether oral glucose tolerance test (OGTT)-derived indexes of insulin secretion and sensitivity could distinguish between these two groups. RESEARCH DESIGN AND METHODS A total of 25 Ab(-), 11 Ab(+) CDx-type 2 diabetic, and 21 obese control youths had an OGTT. Fasting and OGTT-derived indexes of insulin sensitivity (including the Matsuda index, homeostasis model assessment [HOMA] of insulin resistance, quantitative insulin sensitivity check index, and glucose-to-insulin ratio) and insulin secretion (HOMA of insulin secretion and 30-min insulogenic and C-peptide indexes) were used. Glucagon and glucagon-like peptide (GLP)-1 responses were assessed. RESULTS Fasting C-peptide and C-peptide-to-glucose ratio, and C-peptide area under the curve (AUC) were significantly lower in the Ab(+) CDx-type 2 diabetic patients. Other OGTT-derived surrogate indexes of insulin sensitivity and secretion were not different between the Ab(+) versus Ab(-) patients. GLP-1 during the OGTT was highest in the Ab(+) youths compared with the other two groups, but this difference disappeared after adjusting for BMI. Ab(+) and Ab(-) CDx-type 2 diabetes had relative hyperglucagonemia compared with control subjects. CONCLUSIONS The clinical measures of fasting and OGTT-derived surrogate indexes of insulin sensitivity and secretion, except for fasting C-peptide and C-peptide AUC, are less sensitive tools to distinguish metabolic/pathopysiological differences, detected by the clamp, between Ab(+) and Ab(-) CDx-type 2 diabetic youths. This underscores the importance of using more sensitive methods and the importance of determining antibody status in obese youths with CDx-type 2 diabetes.

On the numerical inversion of the Laplace transform and similar Fredholm integral equations of the first kind (1978)

Analytic expressions are derived for the eigenfunctions and eigenvalues of the Laplace transform and similar dilationally invariant integral equations of the first kind. Some generalised concepts of information theory are introduced to show how the use of these eigenfunctions enables the maximum possible amount of information to be obtained when solving the inverse problem numerically. These concepts also explain how the amount of information available depends on the level of noise in the calculation and on the structure of the particular integral kernel. Some numerical examples which illustrate these points are presented.
3D data codec and transmission over the internet (2007)

In this paper, a compression method of encoding/decoding 3D mesh based on octree is proposed. Vertices of the 3D mesh are reclassified according to the octree rule. We analyse all the nodes of the octree statistically to identify the type of nodes which accounts for the max proportion and encode them with fewer bits. According to the transmission sequence of geometric information, we rearrange topology and attribute information and encode them. Progressive strategies adopted by the single model and the scene are different in order to maximize the use of network bandwidth and computational performance of local machines. This method has high compression rate, is adapt to network transmission with short response time at the client and can control the level of detail of the model decoding.
Role of cdk2 in the sequential phosphorylation/activation of C/EBPβ during adipocyte differentiation (2007)

Upon induction of differentiation, growth-arrested (G(1) phase) 3T3-L1 preadipocytes express CCAAT/enhancer binding protein-beta (C/EBPbeta), initiating a transcriptional cascade. C/EBPbeta immediately undergoes a priming phosphorylation (on Thr(188)) by MAPK/ERK. However, the acquisition of DNA binding and transactivation capacity of C/EBPbeta is delayed until further phosphorylation (on Ser(184) or Thr(179)) by GSK3beta occurs. Phosphorylation by glycogen synthase kinase-3beta (GSK3beta) induces S phase entry and thereby mitotic clonal expansion (MCE), a requirement for terminal differentiation. Because MAPK activity is down-regulated before S phase is completed, we sought to identify the kinase that maintains C/EBPbeta in the primed phosphorylated state throughout S phase and MCE. We show here that cdk2/cyclinA, whose expression is activated at the onset of S phase, functions in this capacity. Ex vivo and in vitro experiments show that cdk2/cyclinA catalyzes this delayed priming phosphorylation. Mass spectrometric analysis revealed that cdk2/cyclinA phosphorylates C/EBPbeta on Thr(188) and is required for phosphorylation (on Ser(184) or Thr(179)) of C/EBPbeta by GSK3beta and maintenance of DNA binding activity. Suppression of cdk2 activity by RNA interference or pharmacologic inhibitor disrupts subsequent events in the differentiation program. Thus, MAPK and cdk2/cyclinA act sequentially to maintain Thr(188) of C/EBPbeta in the primed phosphorylated state during MCE and thereby progression of terminal differentiation.
Tuning the Electronic Structure of Titanium Oxide Support to Enhance the Electrochemical Activity of Platinum Nanoparticles (2013)

Two times higher activity and three times higher stability in methanol oxidation reaction, a 0.12 V negative shift of the CO oxidation peak potential, and a 0.07 V positive shift of the oxygen reaction potential compared to Pt nanoparticles on pristine TiO2 support were achieved by tuning the electronic structure of the titanium oxide support of Pt nanoparticle catalysts. This was accomplished by adding oxygen vacancies or doping with fluorine. Experimental trends are interpreted in the context of an electronic structure model, showing an improvement in electrochemical activity when the Fermi level of the support material in Pt/TiOx systems is close to the Pt Fermi level and the redox potential of the reaction. The present approach provides guidance for the selection of the support material of Pt/TiOx systems and may be applied to other metal-oxide support materials, thus having direct implications in the design and optimization of fuel cell catalyst supports.
Human Resource Strategy (1980)

Corporate managers have an increasing need for data on career paths, compensation, and staffing in corporation planning functions in order to better manage their own operations. At the same time, current and potential members of corporate planning staffs need similar information to better guide their careers and activities. This survey was conducted to meet an important part of the needs of both management and staff.

Isolation and Identification of a Novel Mitochondrial Metalloprotease (PreP) That Degrades Targeting Presequences in Plants (2002)

Most of the nuclear encoded mitochondrial precursor proteins contain an N-terminal extension called the presequence that carries targeting information and that is cleaved off after import into mitochondria. The presequences are amphiphilic, positively charged, membrane-interacting peptides with a propensity to form alpha-helices. Here we have investigated the proteolysis of the presequences that have been cleaved off inside mitochondria. A presequence derived from the overexpressed F(1)beta subunit of the ATP synthase and specific synthetic fluorescent peptides (Pep Tag Protease assay) have been shown to undergo rapid degradation catalyzed by a matrix located protease. We have developed a three-step chromatographic procedure including affinity and anion exchange chromatography for isolation of the protease from potato tuber mitochondria. Two-dimensional gel electrophoresis of the isolated proteolytically active fraction followed by electrospray ionization-mass spectrometry/mass spectrometry and data base searches allowed identification of the presequence peptide-degrading protease in Arabidopsis thaliana data base as a novel mitochondrial metalloendoprotease with a molecular mass of 105 kDa. The identified metalloprotease contains an inverted zinc-binding motif and belongs to the pitrilysin family.
Fabrication of graphene by pulsed laser annealing from a graphene oxide thin film (2012)

A laser-based thin-film processing scheme for printing and annealing of graphene oxide is reported. This method is able to print and simultaneously reduce the graphene oxide to graphene. The resulting graphene thin film is with good transmittance and its resistance is dramatically reduced from 200 MΩ to 80 KΩ.
Growth of Argentine Mesquite Inoculated with Vesicular-Arbuscular Mycorrhizal Fungi (1994)

Argentine mesquite (Prosopis alba) seedlings were inoculated with the vesicular-arbuscular mycorrhizal (VAM) fungi, Glomus intraradices , container-grown for five months, and transplanted into a simulated landscape in Tempe, Arizona. After transplanting, mesquite trees were either drip irrigated at regular intervals or nonirrigated for one year. Six months after transplanting, VAM fungal colonization was observed only in the roots of inoculated mesquite but by 12 months, roots of both inoculated and noninoculated mesquite were colonized by VAM fungi. Higher levels of VAM fungal colonization occurred in roots of irrigated mesquite. While irrigation promoted mesquite shoot growth, VAM inoculation inhibited shoot growth of nonirrigated trees. Trunk caliper was greater for irrigated trees than for nonirrigated trees and was not affected by VAM infection. VAM fungi promoted the growth of thinner roots for irrigated trees and thicker roots for nonirrigated trees after six months. At the conclusion of the study, root growth was enhanced by drip irrigation and was not affected by previous VAM fungal inoculation.

A novel retrovirally induced embryonic lethal mutation in the mouse: assessment of the developmental fate of embryonic stem cells homozygous for the 413.d proviral integration (1991)

A genetic screen of transgenic mouse strains, carrying multiple copies of an MPSV neo retroviral vector, has led to the identification of a recessive embryonic lethal mutation, termed 413.d. This mutation is associated with a single proviral insertion and when homozygous, results in the failure of the early postimplantation embryo at the gastrulation stage of development. Embryonic stem cell lines (ES cells) were derived from 413.d intercross embryos. Genotyping, with respect to the 413.d integration site, identified wild-type, heterozygous and homozygous ES cell lines. The differentiation abilities and developmental potential of the ES cell lines were assessed using a number of in vitro and in vivo assays. Results indicate that the ES cell lines, regardless of genotype, are pluripotent and can give rise to tissue and cell types derived from all three germ layers. Furthermore, analysis of midgestation conceptuses (10.5 p.c.) and adult chimeras generated by injecting mutant ES cells into host blastocysts, provides strong evidence that the mutant cells can contribute to all extraembryonic tissues and somatic tissues, as well as to functional germ cells. These results indicate that the homozygous mutant cells can be effectively 'rescued' by the presence of wild-type cells in a carrier embryo.

What Valuation Models Do Analysts Use? (2004)

This paper adopts a structured positive approach to explaining the valuation practices of financial analysts by studying the valuation methodologies contained in 104 analysts' reports from international investment banks for 26 large U.K.-listed companies drawn from the beverages, electronics, and pharmaceuticals sectors. We provide a descriptive analysis of the use of alternative valuation models focusing on the value-relevant attributes that analysts seek to forecast and the methodologies analysts use to convert the forecasts into estimates of firm value. We postulate and test a number of hypotheses relating to how the valuation practices of analysts vary systematically across industrial sectors. We find that: (1) the use of valuation by comparatives is higher in the beverages sector than in electronics or pharmaceuticals; (2) analysts typically choose either a PE model or an explicit multiperiod DCF valuation model as their dominant valuation model; (3) none of the analysts use the price to cash flow as their dominant valuation model; and (4) contrary to our expectations, some analysts who construct explicit multiperiod valuation models still adopt a comparative valuation model as their preferred model. We believe the study's findings are important for increasing our understanding of the valuation practices of financial analysts. The study also provides a basis for further research that tests a richer and more det ailed set of hypotheses.
LEARNING TO SEE (2006)

This is a true story reported several years ago in The New Yorker magazine about a man named Virgil. Virgil had been blind since he was a tiny child. He was diagnosed with retinitis pigmentosa, a hereditary disease that destroys the retina of the eye. He also developed thick cataracts, but since his retina was damaged, the doctors never bothered to remove the cataracts. For the next forty years Virgil was almost totally blind.
Fabrication of BiOBrxI1−x photocatalysts with tunable visible light catalytic activity by modulating band structures (2016)

A series of BiOBrxI(1-x) solid solutions were explored as novel visible light-sensitive photocatalysts. These BiOBrxI(1-x) solid-solution photocatalysts grew into two-dimensional nanoplates with exposed (001) facets and possessed continuously modulated band gaps from 2.87 to 1.89 eV by decreasing the Br/I ratio. The photocatalytic activities of these samples were measured, and the samples exhibited visible light-driven activities for the degradation of Rhodamine B (RhB). In particular, BiOBr0.8I0.2 exhibited the highest activity for the degradation of RhB. This result could be attributed to the balance between the effective light absorption and adequate redox potential. Additionally, investigations into the photocatalytic mechanism showed that the photodegradation of RhB over BiOBr0.8I0.2 solid-solution photocatalysts involved direct holes oxidation, in which the reaction that dominated during photocatalysis was determined by the potential of the valence band. Furthermore, a high stability in the photocatalytic activity of BiOBr0.8I0.2 was demonstrated by the cycling photocatalytic experiment and long-term irradiation, which might offer opportunities for its practical application as a catalyst.
Photophysical and Photochemical Studies of Polycyclic Aromatic Hydrocarbons in Solutions containing Tetrachloromethane. I. Fluorescence Quenching of Anthracene by Tetrachloromethane and its Complexes with Benzene, p-Xylene and Mesitylene (1986)

Distributed model of blood-bone exchange (1986)

An understanding of bone physiology obtained from a knowledge of fluid spaces and their associated barriers may lead to better management of bone pathologies. Such information can be obtained by mathematically modelling the results of multiple tracer outflow dilution techniques, which in our case were performed on the canine tibia. Hence, a computer model was developed to describe the exchange processes of tracers between blood and bone. Capillary permeability, bone binding and the vascular, interstitial fluid and bone volumes of distribution were used as parameters in the equations describing the system, which also used published morphometric bone data. Parameter estimates were then derived by the use of optimization procedures.
