Triiodothyronine (T3) Modulation of Gonadotropin Secretion in the Female Rat (1978)

The effect of T3 upon gonadotropin secretion was examined in ovariectomized (Ovarx), Ovarx thyro-parathyroidectomized (Ovarx-TxPx), or proestrus rats. T3 (50 microgram/-100 gBW), administered late diestrus-2, abolished the LH surge during the critical period of proestrus in 7 out of 9 rats; the rise in sera FSH was not inhibited, although a distinct peak was absent. Administration of 5 or 50 microgram T3/100gBW 2.5h before the critical period resulted in either a suppression or an alteration of the timing of LH release. In the 5 microgram T3/100gBW treated animals the sera FSH peak was delayed in timing, whereas in the 50 microgram T3/100gBW treated rats sera FSH demonstrated two separate peaks during the critical period. Treatment with various dosages of T3 of Ovarx-TxPx rats resulted in significant suppressions (p less than 0.05) of sera LH and FSH. Despite depressed concentrations of sera LH and FSH in T3-treated rats pituitary sensitivity to a challenge of 3LHRH was enhanced. Hence, the pituitary was not the site of T3 inhibition of gonadotropin secretion. Additionally, T3 did not modify pituitary LH content or hypothalamic LH3 releasing activity (LHRH). Since T3 did not inhibit gonadotropin secretion at the pituitary level, a neural site of T3 action is suggested.
Several new classes of measures of fuzziness (2002)

The authors introduce two new general classes of measures of fuzziness, called the additive and multiplicative classes. Usually three axioms are required for fuzziness measures. The classes not only satisfy these three basic axioms, but also two other desirable axioms. The multiplicative class is based on nonnegative, monotone increasing concave functions. The additive class requires only nonnegative concave functions. Constructing a measure of fuzziness under each of these classes is simple, as the required functional form does not have restrictions. It is demonstrated that several existing measures of fuzziness are special cases of these new classes.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">&gt;</ETX>

DNA frayed wires: Differential polymerization of d(AnGm) oligonucleotides (1999)

Oligodeoxyribonucleotides with terminal runs of contiguous guanines, d(AnGm), spontaneously associate into high molecular weight complexes that resolve on polyacrylamide gels as a regular ladder pattern of bands with low mobility. The aggregates, which we call frayed wires, arise from the interaction between the guanine residues of the oligonucleotides; the adenine tracts are single stranded and can take part in Watson–Crick interactions. Oligonucleotides, with different arm-to-stem ratios and total length, readily associate in the presence of Mg2+ to form aggregates consisting of an integer number of strands. The type of the observed aggregates is determined by the length of the guanine run. Oligonucleotides with six guanines form four- and eight-stranded complexes; there is no further polymerization. An increase in the number of guanine residues to 10 and 15 leads to polymerization resulting in a ladder pattern of up to 9 bands and an intense signal at the top of the gel. The relative population of any given species in a frayed wire sample is governed by the guanine stem length and is not affected to any substantial extent by arms up to 40 bases long. The type and concentration of the cation in the solution affect the degree of aggregation, with Na+ and K+ promoting the formation of complexes comprised of 2–4 strands and Mg2+ being the most effective in facilitating polymerization. The electrophoretic behavior of frayed wires was analyzed in the framework of the Ogston theory. The free mobility of frayed wires in the solution is close to the values reported for single-stranded DNA, indicating the equivalence of the charge density of the two conformations. The retardation coefficients for frayed wires arising from a single kind of parent strand increase with the introduction of each additional strand. There is no correlation between the retardation coefficient and the type of parent strand; rather, the magnitude of the retardation coefficient is determined by the total molecular weight of the complex. The values of the retardation coefficients are consistently higher than those for double-stranded DNA and they display much stronger dependence on the total molecular weight. Presumably, the distinct structural and dynamic characteristics of the two conformations account for their different electrophoretic behavior. © 1999 John Wiley & Sons, Inc. Biopoly 49: 287–295, 1999

<title>Document understanding using layout styles of title page images</title> (1992)

An important problem in the application of compound document architectures is the input of data from raster images. One technique is to use visual, syntactic cues found in the layout of the raster document to infer its logical structure or semantics. Another is to use context derived from characters recognized within a given block of raster data. Both character- and image- based information are considered here. A well-constrained environment is defined for use in developing rules that can be applied to basic book title page understanding. This paper identifies the attributes of title page layout objects which aid in mapping them into the fields of a simple bibliographic format. Using as input the raster images of the title page and the verso of the title page along with the ASCII output of a generic character recognition engine from these same images, a system of rules is defined for generating a marked-up text wherein key bibliographic fields may be identified.

Symmetry Breaking in Nanostructure Development of Carbogenic Molecular Sieves:  Effects of Morphological Pattern Formation on Oxygen and Nitrogen Transport (1996)

A comprehensive study has been undertaken to establish the primary factors that control transport of oxygen and nitrogen in polymer-derived carbogenic molecular sieves (CMS). Characterization of the nanostructure of CMS derived from poly(furfuryl alcohol) (PFA) indicates that significant physical and chemical reorganization occurs as a function of synthesis temperature. Spectroscopic measurements show a drastic decrease in oxygen and hydrogen functionality with increasing pyrolysis temperature. Structural reorganization and elimination of these heteroatoms lead to a measurable increase in the unpaired electron density in these materials. High-resolution transmission electron microscopy and powder neutron diffraction are used to probe the corresponding changes in the physical structural features in the CMS. These indicate that as the pyrolysis temperature is increased, the structure of the CMS transforms from one that is disordered and therefore highly symmetric to one that is more ordered on a length scale of 15 Å and hence less symmetric. This structural transformation process, one of symmetry breaking and pattern formation, is often observed in other nonlinear dissipative systems, but not in solids. Symmetry breaking provides the driving force for these high-temperature reorganizations, but unlike most dissipative systems, these less-symmetric structures remain frozen in place when energy is no longer applied. The impact of these nanostructural reorganizations on the molecular sieving character of the CMS is studied in terms of the physical separation of oxygen and nitrogen. These results show that the effective diffusivities of oxygen and nitrogen in the CMS vary by more than an order of magnitude across the range of synthesis temperatures studied. Although the electronic nature of the CMS leads to higher equilibrium capacity for oxygen, it is the physical nanostructure which governs the separation of these two molecules. It is concluded that the primary separation mechanism is steric and configurational in nature, a conclusion in good agreement with the general features of the kinetic hypothesis conjectured by earlier workers.
Portable Magnetic/Frequency Domain Electromagnetic Induction Sensor System Development (2008)

Abstract An unexploded ordnance (UXO) survey instrument that simultaneously collects total field magnetic data and frequency domain electromagnetic (FDEM) induction data was developed and tested for the detection and characterization of buried UXO. The system is comprised of an FDEM sensor operating at 9.8 kHz and a cesium vapor magnetometer. The system was initially tested in dynamic survey (detection) and static cued survey (characterization) modes at the Naval Research Laboratory Blossom Point UXO test facility in Maryland. During these tests, electromagnetic (EM) induced bias in the magnetic data was mitigated by physically offsetting the magnetometer from the EM transmitter coils. In the dynamic survey, the aggregate performance exceeded the detection rates for the individual component sensor technologies. The cued analysis tests showed that target features can be determined by using model-based analyses, and the location estimate errors provided by these analyses were consistently better than the dynamic survey results.
SNECMA Experience With Cost-Effective DS Airfoil Technology Applied Using CM 186 LC® Alloy (1998)

From a cost point of view SNECMA has found DS columnar grain manufacturing technology to be highly attractive compared to single crystal. CM 186 LC alloy exhibits enhanced mechanical and environmental properties and temperature capability compared to MAR M 200 Hf alloy; these properties are close to first-generation single crystal alloys up to 982°C (1800°F). The alloy is shown to be amenable to various coating and brazing high-temperature processes. The longer term creeprupture/phase stability data base on the alloy has now been extended out to 8300 hours at 1038°C (1900°F). Castings for engine test have been produced using CM 186 LC alloy.
Single Chain Antibodies as Estrogen Receptor Repressors in Breast Cancer (2000)

Estrogen&lt;dependent growth and metastasis of breast cancers Is mediated through the estrogen receptor (ER). The objective of these studies is to produce identify and demonstrate the utility of single chain antibodies (scFv) that interfere with ER action. These scFv are derived from the DNA binding domain (DBD) of the ER such that binding of a scFv to the ER DBD would prevent the interaction of the ER with estrogen response elements in the promoter of estrogen responsive genes. The estrogen dependent transcription of such genes results in the proliferation of breast cancer cells. To date several low affinity scFv have been developed. However difficulties in obtaining bacterial expression and correct folding of the scFV have been encountered. Optimizing the expression of scFv is now primarily a bacteriological problem as opposed to providing direct train in breast cancer research. I have therefore also begun to study the promoter of 1-9: an estrogen inducible inhibitor of granzyme B mediated apoptosis. Studying this gene will provide further insight into how breast cancer cells evade immune attack. I have found that the promoter of this gene contains a unique estrogen responsive unit that is capable of binding ER in both gel shift assays and DNAse I footprinting.
Effect of Transmitter Position on the Torque Generation of a Magnetic Resonance Based Motoring system (2019)

Strongly coupled magnetic resonance is most often used to transfer electrical power from a transmitter to a resonant receiver coil to supply devices over an air gap. In this work, the induced current in two receiver coils (stator and rotor) is used to generate torque on the rotor coil. The effect of the transmitter position relative to the stator and rotor receiver coils on the torque generation is studied in detail, both in simulation and experimentally. Results show a 36% to 37% gain in peak torque when properly varying the stator orientation for a given transmitter distance.

Multi-joule energy extraction in diode-pumped Tm:YLF (2022)

We present the first demonstration of a multi-joule diode-pumped Tm:YLF amplifier. The compact demonstrator setup, consisting of a Tm:YLF-based oscillator producing ~20mJ, 20ns pulses at 1880nm wavelength that seeds a diode pumped four-pass Tm:YLF power amplifier, generated pulse energies up to 3.9J with a maximum net gain exceeding 200. No saturation effects were observed within this amplifier, as the output pulse energies increased exponentially with the input pump power. When the amplifier was seeded with the free-running oscillator, with pulse durations still significantly shorter than the 15ms radiative lifetime of Tm:YLF, energies of up to 38J were achieved. To the best of our knowledge, this represents over a 100-fold improvement in the highest reported pulse energy from a Tm:YLF amplifier, and nearly an order of magnitude higher energy than any laser operating near 2μm. These results show that Tm:YLF, when operated in an efficient high repetition rate extraction regime and combined with a high-capacity heat removal technique, has the potential to enable a new class of efficient, high peak and average power laser systems to meet the demands of next generation scientific and industrial applications.
Electron-beam analysis of polymerizedKC60 (1996)

We have conducted high-resolution transmission electron microscopy (HRTEM) and electron-energy-loss spectroscopy (EELS) studies on polymerized ${\mathrm{KC}}_{60}$. The chainlike structure proposed for the polymerized material is confirmed. Lattice constants extracted from the HRTEM images are consistent with those determined earlier by x-ray diffraction. The fine structure in the EELS spectrum of ${\mathrm{KC}}_{60}$ shows the ${\mathit{sp}}^{2}$ nature of the carbon bonds along with features which distinguish the bonding in this alkali fulleride from that of other fullerenes. Both the HRTEM and EELS studies show that polymerized ${\mathrm{KC}}_{60}$ is exceedingly resilient against damage induced by a 200-keV electron beam, in sharp contrast to the behavior of pristine ${\mathrm{C}}_{60}$. \textcopyright{} 1996 The American Physical Society.

Plane‐of‐sky simulations of interplanetary shock waves (2003)

We present simulated plane‐of‐sky maps of the shock waves in interplanetary space from several representative solar events by using the Hakamada‐Akasofu‐Fry solar wind model (HAFv.2). This kinematic model uses a three‐dimensional approach to construct plane‐of‐sky maps of interplanetary shock waves initiated by solar flares and CMEs. The simulated plane‐of‐sky maps are in a form that can be directly compared with assimilated optical observations of shock waves from Earth‐orbiting and interplanetary satellites. Combining these simulations with observations would provide a new tool for monitoring the propagation of interplanetary shocks in interplanetary space and for predicting the arrival of shock waves at Earth.
Competition for peptides and amino acids among periodontal bacteria (1995)

We recently studied the utilization of glutathione (L-gamma-glutamyl-L-cysteinylglycine), L-cysteinylglycine and L-cysteine by anaerobic bacteria. The rate of hydrogen sulfide formation from these compounds was determined and it was concluded that Peptostreptococcus micros and Fusobacterium nucleatum subsp. nucleatum had an active transport of small peptides. In the present study it is shown that methyl mercaptan formation from L-methionine and L-methionyl-containing peptides can also be used to study peptide utilization. There were differences among the periodontal bacteria P. micros, F. nucleatum subsp. nucleatum, and Porphyromonas gingivalis in their capacity to use L-cysteine and L-methionine and peptides containing these amino acids. The peptides were used more efficiently by P. micros and F. nucleatum subsp. nucleatum than by P. gingivalis. All three species used the peptides more efficiently than the free amino acids. The efficiency in utilizing various amino acids and peptides may be among the key determinants of the periodontal microbial ecology.
The most widespread phage in animals: Genomics and taxonomic classification of Phage WO (2021)

Abstract Wolbachia are the most common obligate, intracellular bacteria in animals. They exist worldwide in arthropod and nematode hosts in which they commonly act as reproductive parasites or mutualists, respectively. Bacteriophage WO, the largest of Wolbachia ’s mobile elements, includes reproductive parasitism genes, serves as a hotspot for genetic divergence and genomic rearrangement of the bacterial chromosome, and uniquely encodes a Eukaryotic Association Module with eukaryotic-like genes and an ensemble of putative host interaction genes. Despite WO’s relevance to genome evolution, selfish genetics, and symbiotic applications, relatively little is known about its origin, host range, diversification, and taxonomic classification. Here we analyze the most comprehensive set of 150 Wolbachia and phage WO assemblies to provide a framework for discretely organizing and naming integrated phage WO genomes. We demonstrate that WO is principally in arthropod Wolbachia with relatives in diverse endosymbionts and metagenomes, organized into four variants related by gene synteny, often oriented opposite the origin of replication in the Wolbachia chromosome, and the large serine recombinase is an ideal typing tool to assign taxonomic classification of the four variants. We identify a novel, putative lytic cassette and WO’s association with a conserved eleven gene island, termed Undecim Cluster, that is enriched with virulence-like genes. Finally, we evaluate WO-like Islands in the Wolbachia genome and discuss a new model in which Octomom, a notable WO-like Island, arose from a split with WO. Together, these findings establish the first comprehensive Linnaean taxonomic classification of endosymbiont phages that includes distinguishable genera of phage WO, a family of non- Wolbachia phages from aquatic environments, and an order that captures the collective relatedness of these viruses.
Life cycle management as a business strategy for sustainability (2003)

Abstract Today's business climate demands signifcant shzfts in how organizations deliver products and services to customers. Firms in many industrial sectors are effectively using management systems and life cycle assessments to understand and improve their operations, products, and services. But, a more comprehensive approach is needed to significantly reduce the pressure on natural systems, and to successfully respond to the increased complexity of business decision‐making in the 21st centuly. This paper discusses life cycle management as an effective business strategy that can continually respond to these unique new challenges.
When Several Bayesians Agree That There Will Be No Reasoning to a Foregone Conclusion (1999)

When can a Bayesian investigator select an hypothesis H and design an experiment (or a sequence of experiments) to make certain that, given the experimental outcome(s), the posterior probability of H will be lower than its prior probability? We report an elementary result which establishes sufficient conditions under which this reasoning to a foregone conclusion cannot occur. Through an example, we discuss how this result extends to the perspective of an onlooker who agrees with the investigator about the statistical model for the data but who holds a different prior probability for the statistical parameters of that model. We consider, specifically, one-sided and two-sided statistical hypotheses involving i.i.d. Normal data with conjugate priors. In a concluding section, using an “improper” prior, we illustrate how the preceding results depend upon the assumption that probability is countably additive.
