The Electrodeposition of Molybdenum Alloys (1949)

A new aqueous citrate plating bath for the electrodeposition of alloys of molybdenum with cobalt, iron, and nickel is described. This type of plating solution contains the sulfate of the codepositing metal citric acid, and sodium molybdate. Ammonium hydroxide is used for adjusting the pH of the solution. A bath temperature of about 25 C is preferred. Experimental results, obtained by using the Hull cell for qualitative information and regular plating procedures for quantitative data, show the effect of bath pH, concentration of sodium molybdate, and cathode current density on the performance of the plating baths. The highest percentage of molybdenum (about 50% and more) is obtained with iron as the codepositing metal, and the lowest is with nickel.
Bacterial topoisomerase I as a target for discovery of antibacterial compounds (2008)

Bacterial topoisomerase I is a potential target for discovery of new antibacterial compounds. Mutant topoisomerases identified by SOS induction screening demonstrated that accumulation of the DNA cleavage complex formed by type IA topoisomerases is bactericidal. Characterization of these mutants of Yersinia pestis and Escherichia coli topoisomerase I showed that DNA religation can be inhibited while maintaining DNA cleavage activity by decreasing the binding affinity of Mg(II) ions. This can be accomplished either by mutation of the TOPRIM motif involved directly in Mg(II) binding or by altering the charge distribution of the active site region. Besides being used to elucidate the key elements for the control of the cleavage-religation equilibrium, the SOS-inducing mutants of Y. pestis and E. coli topoisomerase I have also been utilized as models to study the cellular response following the accumulation of bacterial topoisomerase I cleavage complex. Bacterial topoisomerase I is required for preventing hypernegative supercoiling of DNA during transcription. It plays an important role in transcription of stress genes during bacterial stress response. Topoisomerase I targeting poisons may be particularly effective when the bacterial pathogen is responding to host defense, or in the presence of other antibiotics that induce the bacterial stress response.
Social support as a predictor of variability: An examination of the adjustment trajectories of recent widows. (2006)

The variability pattern of emotional well-being in recent widows across a 98-day period beginning in the first month post-loss has previously been modeled by dynamical systems and shown to be an oscillating process that damps across time. The goal of the present study was to examine how variables that comprise the social support network predict characteristics of these emotional shifts in 28 recent widows. In the present study, emotional support seeking led to a steeper overall trend, whereas perceived control for social support led to a shallower overall trend. When examining intraindividual variability, instrumental support seeking predicted a slower damping rate. Understanding the individual differences in the variability patterns of recent widows is a necessary step in identifying the etiology of adjustment to widowhood.

Breeding of a Shochu Yeast Isolated from Barley-Shochu Mash (1995)

The isolation of yeast strain suitable for barley-shochu making was carried out from Saccharomyces cerevisiae Kagoshima yeast (Ko). Among strains isolated from barley-shochu mash, the strain W-6 possessed high ethanol-tolerance as well as high proliferation potency in 8-10% ethanol/barley-koji medium. Furthermore, W-6 was more tolerant to citric acid than Ko. From the result of small-scale barley-shochu making, it was proved that ethanol concentration in the mash using the strain W-6 washigher than that using the strain Ko at the last stage of fermentation. When W-6 was used for barley-shochu making, ethanol productivity from barley increased to 4171/t. It was thus confirmed that W-6 possessed good characters to make it a suitable strain to be applied in brewing of barley-shochu.
Signal processing strategies in acoustic elastography (2002)

Elastography is a remote sensing technique for imaging the elastic properties of biological tissues. An essential feature is tissue deformation (strain) that is measured by cross correlating ultrasonic echo waveforms acquired before and after a weak static compression. To fully exploit the large object contrast available among body tissues, many dependent experimental parameters must be carefully adjusted. This paper outlines a strategy for selecting the applied stress field including boundary conditions, transducer frequency and bandwidth, and echo window length and overlap that minimize elastographic noise and maximize dynamic range for a given spatial resolution.

Design-for-test strategies for analogue and mixed-signal integrated circuits (2002)

Recent advances in technology are leading to increases in the complexity and applications of analogue and mixed-signal integrated circuits. This trend has been accompanied by an increase in the complexity of associated test specifications. Furthermore, the use of functional and specification based test programs for the analogue circuitry is being questioned due to high implementation costs, the difficulties associated with quantifying the effectiveness of the tests and in many cases difficulties in accessing embedded analogue macros. In addition quality levels expected by integrated circuit (IC) users are increasing, with typical targets currently being better than 40 ppm defect levels. New test solutions are therefore required for these circuit types. Design-for-Test (DfT) strategies are well established for digital circuits, whilst for analogue and mixed signal circuits, few techniques have been proposed and implementation of custom approaches is rare. This paper presents a summary of a number of possible approaches for improving test access by increasing both controllability and observability of internal functional blocks in analogue and mixed-signal ICs, evaluating both their effectiveness and their impact on circuit performance.
An automated multimodal face recognition system based on fusion of face and ear (2009)

This thesis presents an automated system for the detection and recognition of humans using a multimodal approach. Face recognition is a biometric method which has in recent years become more relevant and needed. With heavy research, it is achieving respectable recognition rates and is becoming more mature as a technology. It is even being deployed in certain situations such as with passports and credit cards. Our multimodal biometric system uses both a person's face and ear to improve the recognition rate of individuals. By combining these two biometric systems we are able to achieve significantly improved recognition rates, as compared to using a unimodal biometric system. The system is totally automated, with a trained detection system for face and one for ear. We look at recognition rates for both face and ear, and then at combined recognition rates, and see that we have significant performance gains from the multimodal approach. We also discuss many existing methods of combining biometric input and the recognition rates that each achieves. Experimental results indicate that a multimodal biometric system has higher recognition rates than unimodal systems. This type of automated biometric recognition system can easily be used in installations requiring person identification such as person recognition in mugshots. It can also be used by security agencies and intelligence agencies requiring robust person identification systems.
Development of cold-formed steel moment-resisting frames using optimum beams in seismic applications (2018)

Cold-Formed steel (CFS) elements are increasingly being used as the main load-carrying members in modern construction, including in seismic regions. The main deficiency of CFS elements is their susceptibility to premature buckling due to their limited thickness, which results in less seismic energy dissipation and lower ductility compared to their conventional hot-rolled counterparts. However, the seismic characteristics of CFS elements can be increased by using more efficient cross-sectional shapes. This paper aims to improve the seismic performance and post-buckling behaviour of CFS lipped channel sections by optimising their geometry to achieve maximum energy dissipation capacity under cyclic loads. A novel optimisation framework is presented, using the Particle Swarm Optimisation (PSO) method, linked to detailed non-linear finite element models in ABAQUS. The relative dimensions of the cross-section and the inclination of the lip stiffeners are considered as the main design variables. All Eurocode 3 plate slenderness limit values and limits on the relative dimensions of the cross-sectional components, as well as a range of practical and manufacturing limitations, are considered as design constraints in the optimisation problem. It is shown that the proposed optimisation method can significantly increase the energy dissipation capacity of the CFS sections. Subsequently, the assessment of CFS beams connections is conducted by simulations of cyclically loaded moment resisting connections using an experimentally validated model. Finally, the efficiency of the optimised sections is investigated at the structural level by conducting non-linear cyclic analyses on a CFS moment resisting portal frame with CFS back-to-back lipped channel sections for the columns and the beam. The results indicate that using the optimised CFS sections can considerably improve the seismic performance of the CFS frames, leading to higher energy dissipation capacity and lower global damage under strong earthquakes.
Fibroblast growth factor 23 is associated with the presence of coronary artery disease and the number of stenotic vessels (2015)

Fibroblast growth factor 23 (FGF23) has been reported to be involved in cardiovascular disease. The aim of this study was to investigate the association between FGF23 and the presence of coronary artery disease (CAD), as well as the number of stenotic vessels. A total of 254 eligible participants (167 men and 87 postmenopausal women) were enrolled in this study. Coronary angiography was used for diagnosis of CAD. Serum intact FGF23 levels were determined by a two-sided sandwich enzyme-linked immunosorbent assay. The median serum FGF23 levels of the entire study population were 39.9 (33.1-47.5) pg/mL. Serum FGF23 levels were higher in subjects with one-vessel disease than those without CAD (P < 0.05), which further increased significantly in the subjects with multi-vessel disease (P < 0.05). Serum FGF23 levels increased with cumulative number of stenotic vessels (P for trend < 0.001). Multiple stepwise regression analysis revealed estimated glomerular filtration rate (standardized β = -0.298; P < 0.001) and body mass index (standardized β = 0.132; P = 0.049) were independent factors correlated with FGF23. Multivariate logistic regression analysis showed that FGF23 was positively and independently associated with the presence of CAD (odds ratio = 1.058, 95% confidence interval = 1.025-1.092; P = 0.001). Additionally, FGF23 was also correlated with multi-vessel disease significantly (odds ratio = 1.034, 95% confidence interval = 1.007-1.062; P = 0.013). In conclusion, serum FGF23 levels exhibit positive and independent association with the presence of CAD and increase with the cumulative number of stenotic vessels.
Short Circuit Current of Induction Generators (2007)

This paper addresses the effect of distributed generators, specifically squirrel cage induction generators, on 3-ϕ bolted short-circuit fault currents to make sure that they do not interfere with the interruption capability of circuit breakers. Results of a laboratory experiment, and simulation results for 16 different induction machines, including their feeder and transformer connections to the substation, are presented for a short-circuit at the substation site. An equation was developed for the upper boundary envelope of the current peaks contributed by the induction generators, and was used for successful comparison with simulation results.
Uncoupling protein-1 deficiency promotes brown adipose tissue inflammation and ER stress (2018)

Inflammation and endoplasmic reticulum (ER) stress are hallmarks of metabolic syndrome. While these metabolic derangements have been well-investigated in white adipose tissue, their existence and etiology in brown adipose tissue (BAT) are poorly understood. Here, we aimed to investigate ER homeostasis and the inflammatory status and of BAT lacking uncoupling protein-1 (UCP1), a protein required for BAT thermogenesis. H&E staining illustrated lipid accumulation and crown-like structures surrounding adipocytes in BAT of UCP1-/- mice housed at room temperature compared to control mice. Further, immunohistological evaluation of F4/80 and gene expression studies demonstrated BAT macrophage infiltration and robust elevation of pro-inflammatory markers in UCP1-/- BAT. ER stress was also present in BAT of UCP1-/- mice, as evidenced by elevated gene expression and post-translational modifications of unfolded protein response components. After four weeks of thermoneutral housing, UCP1-/- mice did not exhibit elevated BAT inflammation and ER stress gene expression compared to WT mice, but depot expansion persisted. Collectively, we demonstrate that the effects of UCP1 deficiency in BAT are not restricted to mitochondrial uncoupling. We conclude that brown adipose tissue of UCP1-/- mice exhibits pro-inflammatory immune cell infiltration and perturbations in ER homeostasis and that this phenotype is driven by cold exposure rather than lipid accumulation.
Histopathological atlas of renal diseases: Minimal Change disease and focal glomerulosclerosis (2005)

Minimal Change disease and focal segmental glomerulosclerosis are both clinically characterized by presence of Nephrotic Syndrome. The term Minimal Change disease describes a pathology appearance on light microscopy in which there are no definitive changes from normal glomeruli, although the degree of change that is considered significant remains the subject of some controversy. The focal segmental glomerulosclerosis is morphologically characterized by a segmental solidification of the glomerular tuft, due to collapse of the capillary wall, affecting only some glomeruli (focal). It remains unresolved whether Minimal Change disease and focal segmental glomerulosclerosis are different diseases or whether they represent a spectrum of presentation of the same disease process.
Identification of a Gatekeeper Residue That Prevents Dehydrogenases from Acting as Oxidases (2008)

The oxygen reactivity of flavoproteins is poorly understood. Here we show that a single Ala to Gly substitution in l-galactono-gamma-lactone dehydrogenase (GALDH) turns the enzyme into a catalytically competent oxidase. GALDH is an aldonolactone oxidoreductase with a vanillyl-alcohol oxidase (VAO) fold. We found that nearly all oxidases in the VAO family contain either a Gly or a Pro at a structurally conserved position near the C4a locus of the isoalloxazine moiety of the flavin, whereas dehydrogenases prefer another residue at this position. Mutation of the corresponding residue in GALDH (Ala-113 --> Gly) resulted in a striking 400-fold increase in oxygen reactivity, whereas the cytochrome c reductase activity is retained. The activity of the A113G variant shows a linear dependence on oxygen concentration (k(ox) = 3.5 x 10(5) m(-1) s(-1)), similar to most other flavoprotein oxidases. The Ala-113 --> Gly replacement does not change the reduction potential of the flavin but creates space for molecular oxygen to react with the reduced flavin. In the wild-type enzyme, Ala-113 acts as a gatekeeper, preventing oxygen from accessing the isoalloxazine nucleus. The presence of such an oxygen access gate seems to be a key factor for the prevention of oxidase activity within the VAO family and is absent in members that act as oxidases.
Acute aflatoxicosis in feeder pigs, resulting from improper storage of corn (1989)

Aflatoxicosis was diagnosed in 600 feeder pigs, of which 400 died, 150 were destroyed, and 50 were marketed. The pigs were exposed to 2,500 to 3,500 micrograms of aflatoxins/kg of feed. Drought-stressed damaged corn infected with Aspergillus flavus was stored under ambient conditions in a glass-lined silo, and this storage environment provided conditions that favored rapid fungal growth and mycotoxin production.

Cost of treatment of congenital dislocation of the hip (1991)

Early treatment for congenital dislocation of the hip is usually simple and inexpensive. However, if the disease is not detected by 6 months of age, treatment is often complicated and expensive. We evaluated the potential cost-saving of screening, by examining the costs in 36 late cases born in 1980 and found an average cost of pounds 6,674 per case for treatment to this date. This amount could justifiably be spent on each case detected in an effective screening programme.

<title>Generalized Mie theory of light scattering by annular anisotropic layer: anisotropy effects</title> (2001)

We describe the method to extend the generalized Mie approach to the case of light scattering by uniformly anisotropic spherical particles by relating the wave packet representation and expansions for electromagnetic field over spherical harmonics. As a result, we define quasi-spherical modes in anisotropic medium. For radially anisotropic layer we determine the region of validity of Rayleigh-Gans approximation by comparing approximate values of the scattering cross-section with the results computed from the exact solution. We study the relative error for the scattering cross section as a function of the particle size, the anisotropy parameter and the layer thickness.
High Plasma Phospholipid Transfer Protein Levels as a Risk Factor for Coronary Artery Disease (2003)

These findings indicate that PLTP activity is positively and independently related to CAD and suggest that (1) prospective studies to evaluate this relationship are warranted and (2) PLTP should be considered a therapeutic target.
