Glimpses of my journey (2015)

I am an explorer. I work in a personal and private way, which enhances my own journey of exploration and discovery. My site-interactive ceramic sculptures intensify the bond of energy that exists between myself and nature, revitalizing me and reaffirming that which I know to be true or of value. I deliberately create startling or unsettling conditions that are intended to provide a glimpse into unexplored inner realms, challenging myself and viewers to engage in exploration. My work is not a finished product, but a continuing process. The process begins with my exploration of the surrounding mountains, with my search for sites with which I feel an inner connection. This exploration inspires the construction of site-interactive sculptures which I call Spirit Vessels: ceramic sculptures which function as containers for my spirit and as focal points for my thoughts and energy. I choose shapes, colors, textures and a scale which unify the vessels with their sites. I return often to the sites, frequently bringing back rocks to guide me in the treatment of each work’s surface. At times, I texture my work with these rocks by pounding or pressing them into the wet clay.
Upconversion Fluorescence Resonance Energy Transfer Biosensor with Aromatic Polymer Nanospheres as the Lable-Free Energy Acceptor (2012)

We report a new upconversion fluorescence resonance energy transfer (UC-FRET) biosensor using poly-m-phenylenediamine (PMPD) nanospheres as the energy acceptor in this paper. A single-stranded DNA (ssDNA) tagged with a sulfydryl group at the 5'-terminus was covalently linked to poly(ethylenimine) (PEI) functionalized upconversion phosphors (UCPs, the energy donor). Because of the π-rich electronic structure of PMPD, self-assembly of the donor and the acceptor was achieved through the π-π stacking interaction between ssDNA and PMPD. The fluorescence of the donor was quenched by the acceptor in a PMPD-concentration-dependent manner. A maximum quenching degree of 90% was acquired, which was among the highest levels of all previous reports. Upon the formation of double-stranded DNA (dsDNA) between the target DNA and the probe DNA, the energy acceptor was separated from the donor due to the weakened interaction between dsDNA and PMPD. The fluorescence of UCPs was accordingly restored, and a linear response was obtained with the target concentration ranging from 0.1 to 6.0 nM. The limit of detection was calculated as 0.036 nM, which was a highly competitive sensitivity. The sensor also showed high precision, pronounced specificity, and the applicability to complicated sample matrix (human serum). The UCPs-PMPD FRET sensing platform takes advantages of both the optical merits of the upconversion donors and the superquenching ability and good water-solubility of the aromatic polymer nanoparticles. This study will open the opportunity to develop a new class of UC-FRET biosensors.
A bioassay for derivatives of qinghaosu (artemisinin). (1992)

A sensitive bioassay was developed for measuring the serum antimalarial activity for qinghaosu (artemisinin) derivatives. This should assist in the formulation of optimum regimens for the treatment of P. falciparum malaria.
Megagauss Physics (1973)

Fields greater than 10 MG can be produced by explosive flux compression and fields up to 3 MG with capacitor banks. Measurement of fields up to 10 MG is reliable, but difficulties may be expected at higher fields. Megagauss fields have been applied successfully as high-pressure sources, in high-energy particle physics, and in solid-state investigations. Other uses remain to be exploited: plasma compression by megagauss fields has been relatively unsuccessful but shows promise; their use as particle accelerators has been studied only theoretically; and much work remains to be done, both experimentally and theoretically, in connection with applications of megagauss fields in solidstate physics. Note added in proof: Since this article was prepared, Grigor'ev et al. have carried out some experiments (48) in which they have compressed hydrogen up to a density of 1.95 grams per cubic centimeter with a calculated pressure of 8 x 10(6) atmospheres. They report five different pressure-density points and claim that their data can be explained by assuming that the transition to the metallic phase occurs at a pressure of 2.8 x 10(6) atmospheres, with a density change from 1.08 to 1.3 g/cm(3). Using the flux compression techniques described earlier in this article, Hawke et al. [see (30, 31)] have obtained a pressure-density point at 1.5 x 10(6) atmospheres and 1.0 g/cm(3), which is also not inconsistent with a predicted equation of state of metallic hydrogen (49). In view of the experimental uncertainties, none of the pressure-density data can yet be used conclusively to establish the transition's existence. Hawke and his co-workers are presently engaged in measurements of the electrical conductivity of the compressed hydrogen. Observation of a significant conductivity at the proposed transition pressure would be a more definitive test of a metallic transition. In addition, two lower pressure-density points have been obtained for deuterium by the Los Alamos group, by means of the flux compression methods described earlier in this article. One point agrees to within experimental error with a slight extrapolation of Stewart's data (50). The second point is at a pressure of 65+/- 3 x 10(3) atmospheres with a density of 0.71 +/- 0.10 g/cm(3). The data are tentative, and efforts are under way to obtain more data points at both higher and lower pressures.

Measurement of proviral genes in uninfected and avian myeloblastosis virus-infected cells by hybridization with 3H-labeled complementary DNA probe excess (1977)

Viral RNA (vRNA) from avian myeloblastosis virus or DNA from virus-infected and uninfected cells was hybridized with [3H]DNA complementary to viral RNA ([3H]cDNA) under conditions of [3H]cDNA excess. When [3H]cDNA was used to drive the hybridization reaction with vRNA, a rate constant of 33.2 liters/mol-s was obtained. The same rate constant was obtained when vRNA excess was used as the driver. The specific activities of the [3H]DNA probe, estimated from kinetic measurements of the hybridization reaction and from the amount of [3H]cDNA in hybrid form at equilibrium, were 9.1 and 8.6 cpm/pg, respectively. DNA isolated from uninfected cells contained five or six copies of proviral DNA per cell genome. DNA isolated from erythrocytes infected with avian myeloblastosis virus had an additional five or six viral genes added to the cell genome, and the virus-infected target cell (myeloblasts) contained about 15 additional copies of proviral DNA per cell. The use of excess [3H]cDNA probe is an easy and accurate method to quantify the frequency of proviral DNA sequences in cell DNA and to measure a small amount (40 to 200 pg) of vRNA. Probe excess hybridization offers a number of advantages over other procedures and these are discussed.

Risk of dysplasia and adenocarcinoma following restorative proctocolectomy for ulcerative colitis (2006)

Based on these data a surveillance programme should begin at 10 years from the onset of disease. Patients with dysplasia or carcinoma in the original specimen, those with type C ileal mucosal changes and patients with sclerosing cholangitis should be selected for surveillance. This will involve multiple biopsies of the ileal reservoir and the anorectal mucosa below the ileo-anal anastomosis.
Wavelet methods in statistics: Some recent developments and their applications (2007)

The development of wavelet theory has in recent years spawned applications in signal processing, in fast algorithms for integral transforms, and in image and function representation methods. This last application has stimulated interest in wavelet applications to statistics and to the analysis of experimental data, with many successes in the efficient analysis, processing, and compression of noisy signals and images. This is a selective review article that attempts to synthesize some recent work on ``nonlinear'' wavelet methods in nonparametric curve estimation and their role on a variety of applications. After a short introduction to wavelet theory, we discuss in detail several wavelet shrinkage and wavelet thresholding estimators, scattered in the literature and developed, under more or less standard settings, for density estimation from i.i.d. observations or to denoise data modeled as observations of a signal with additive noise. Most of these methods are fitted into the general concept of regularization with appropriately chosen penalty functions. A narrow range of applications in major areas of statistics is also discussed such as partial linear regression models and functional index models. The usefulness of all these methods are illustrated by means of simulations and practical examples.
The high burn-up structure in nuclear fuel (2010)

During its operating life in the core of a nuclear reactor nuclear fuel is subjected to significant restructuring processes determined by neutron irradiation directly through nuclear reactions and indirectly through the thermo-mechanical conditions established as a consequence of such reactions. In today's light water reactors, starting after ∼4 years of operation the cylindrical UO2 fuel pellet undergoes a transformation that affects its outermost radial region. The discovery of a newly forming structure necessitated the answering of important questions concerning the safety of extended fuel operation and still today poses the fascinating scientific challenge of fully understanding the microstructural mechanisms responsible for its formation.
Growth of g‐C<sub>3</sub>N<sub>4</sub> Layer on Commercial TiO<sub>2</sub> for Enhanced Visible Light Photocatalytic Activity (2014)

Novel visible light photocatalytic graphitic carbon nitride/TiO 2 (g‐C 3 N 4 /TiO 2 ) composite samples were synthesized by heating mixtures of melamine and commercial TiO 2 (TO) at different weight ratios. The samples were characterized by X‐ray diffraction (XRD), X‐ray photoelectron spectroscopy (XPS), transmission electron microscopy (TEM), photoluminescence spectroscopy (PL), Fourier transform infrared spectroscopy (FTIR), and UV‐visible diffused reflectance spectroscopy (UV‐vis DRS). Characterization confirms formation of nanocomposites of g‐C 3 N 4 /TiO 2 . At the optimized precursor weight ratio (), the samples exhibited highest adsorption capacity and visible light photocatalytic activity, measured by degradation of methylene blue (MB). Under visible light irradiation, the excited electrons on the surface of g‐C 3 N 4 transfer easily to the conduction band (CB) of TiO 2 via the well‐built heterojunction. The g‐C 3 N 4 /TiO 2 nanocomposites exhibit enhanced visible light catalytic activity due to increased visible light adsorption and effective separation of photogenerated electron‐hole pairs. These g‐C 3 N 4 /TiO 2 nanocomposites could find broad applicability in environmental protection due to their excellent visible light photocatalytic property and facile, cost‐effective preparation process.
Analog Computers for Coordinate Transformation (1952)

Problems in multicomponent analysis frequently require repetitive solutions of a set of simultaneous equations in which the coefficient terms do not change. In these cases it is advantageous to obtain a general solution from which the specific solutions may be obtained readily with simple instruments. An instrument is described which will solve a three-equation set as rapidly as an operator can set the values on the input dials and will simultaneously present the three answers with an accuracy of better than 0.2 percent of maximum value. A method is presented for calculating the accuracy of computation for use in the design of instruments of this type.
[Therapy of Campylobacter pylori infection]. (1988)

A simple and efficient therapy eradicating C. pylori with high reliability from gastroduodenal mucosae is presently unknown. In regard to such a "puristic" approach, antibiotics given as monotherapy are presently as ineffective as bismuth salts, which may temporarily reduce the bacterial density, but yield a low complete bacterial eradication rate of not more than 10% to 30% of all patients. Pilot studies are being performed in many centers to identify more efficacious drugs or combinations. Alternative modalities, such as manipulation of mucus, active vaccination, or clearing of bacterial sources in the environment, presently represent nothing but hypothetical models. Bismuth salts might play an important future role in a more "pragmatic" approach, which investigates any potential clinical benefit derived from a mere suppression of bacterial growth, possibly resulting in a temporary restoration of the mucosal integrity. However, this approach will probably fail to modify the long-term natural history of C. pylori-associated chronic gastritis and its sequelae.
Automatic Mineral Map Generation Procedure From Imaging Spectrometer Data (2005)

An airborne imaging spectrometer collected data for 128 wave length channels covering from near to short wavelength infrared across a 320 m swath, to help obtain a mineral map of an area based on reflectance spectral signatures of the area. Minerals have distinctive crystal structures and chemical contents which can be identified by their light absorption characteristics, and an optimized automatic mineral map generation procedure for imaging spectrometer data was developed. The procedure generates two types of mineral maps, a mineral distribution map showing spatial layout of various minerals and a mineral composition map showing the percentage composition of a selected mineral.
A simple broad-band device de-embedding method using an automatic network analyzer with time-domain option (1989)

A simple method for de-embedding S parameters of devices in microstrip is presented. The use of only one transmission line and two nonideal shorts or opens of different lengths as calibration standards allows the determination of the unknown S parameters of the connectors and the complex propagation coefficient of the lines.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">></ETX>
Over de houdbaarheid van snijbloemen (1957)

Having established that cut flowers last longer by adding such solutions as sugars, bactericides or acids to the vase water, their mechanism of action was investigated.Bacteria and fungi had a direct plugging effect, but also acted indirectly on the water conduction of the flower stalk by secreting toxins. A third kind of plugging occurred independent of micro-organisms as a reaction to wounding and intrusion of air. This plugging could be limited by reducing 02 concentration, lowering the pH and by adding Ca(N0 3 ) 2 .The addition of sugar prevented disintegration of cells through lack of respiratory substrate. In times of higher respiratory activity of the flower parts, the optimum sugar concentration needed in the water increased.Attempts to decrease respiratory activity of the flower by adding respiratory inhibitors failed. Only in Matthiola could the respiratory activity be decreased by gibberellic acid; at the same time the flowers lasted longer.Boron had a favourable effect in Convallaria, Dianthus, Lathyrus and Syringa. Its addition decreased the optimum sugar concentration. In Dianthus it acted on the distribution of dry matter within the flower during development.The possibilities were discussed of practical application of chemicals to make cut flowers last longer.
Genetic Analysis of Diversity within a Chinese Local Sugarcane Germplasm Based on Start Codon Targeted Polymorphism (2014)

In-depth information on sugarcane germplasm is the basis for its conservation and utilization. Data on sugarcane molecular markers are limited for the Chinese sugarcane germplasm collections. In the present study, 20 start codon targeted (SCoT) marker primers were designed to assess the genetic diversity among 107 sugarcane accessions within a local sugarcane germplasm collection. These primers amplified 176 DNA fragments, of which 163 were polymorphic (92.85%). Polymorphic information content (PIC) values ranged from 0.783 to 0.907 with a mean of 0.861. Unweighted pair group method of arithmetic averages (UPGMA) cluster analysis of the SCoT marker data divided the 107 sugarcane accessions into six clusters at 0.674 genetic similarity coefficient level. Relatively abundant genetic diversity was observed among ROC22, ROC16, and ROC10, which occupied about 80% of the total sugarcane acreage in China, indicating their potential breeding value on Mainland China. Principal component analysis (PCA) partitioned the 107 sugarcane accessions into two major groups, the Domestic Group and the Foreign Introduction Group. Each group was further divided based on institutions, where the sugarcane accessions were originally developed. The knowledge of genetic diversity among the local sugarcane germplasm provided foundation data for managing sugarcane germplasm, including construction of a core collection and regional variety distribution and subrogation.
Oxidative Targets in the Stratum corneum (2001)

As the outermost layer of skin, the stratum corneum (SC) is continuously exposed to an oxidative environment, including air pollutants, ultraviolet radiation, chemical oxidants, and aerobic microorganisms. Human SC reveals characteristic antioxidant and protein oxidation gradients with increasing antioxidant depletion and protein oxidation towards the outer layers. SC antioxidants, lipids, and proteins are oxidatively modified upon treatments with ultraviolet A/ultraviolet B, ozone, and benzoyl peroxide. alpha-Tocopherol represents the predominating SC antioxidant with respect to its concentration and its unique susceptibility to the various oxidative challenges tested. In sites rich in sebaceous glands, alpha-tocopherol is physiologically delivered to the surface via secretion of sebum. Oxidative damage in the human SC represents an early pathophysiological event preceding barrier disruption and inflammation in environmentally challenged skin. Furthermore, oxidative gradients in SC proteins may have implications for the process of desquamation in human skin.
Atomic Hydrogen as a Reducing Agent (1965)

Atomic hydrogen is a powerful chemical reducing agent. It may be used to perform reductions at lower temperatures than those achieved in molecular hydrogen, and since it is electrically neutral it is not subject to shielding effects. Because of the contradictory results reported in the literature, an investigation was undertaken to determine optimum ways to produce and transfer atomic species. It is concluded that electrodeless discharge is the most reliable way of production, and that, although Teflon and phosphoric acid coated glass have very low catalytic activities toward recombination, Pyrex and quartz are satisfactory container materials. Reduction temperatures in both molecular and atomic hydrogen were established for a variety of oxides, and the latter were found to be substantially lower. Finally, the advantages and limitations of atomic hydrogen as a reducing agent are considered.
