Wide bandgap engineering of (AlGa)2O3 films (2014)

Bandgap tunable (AlGa)2O3 films were deposited on sapphire substrates by pulsed laser deposition (PLD). The deposited films are of high transmittance as measured by spectrophotometer. The Al content in films is almost the same as that in targets. The measurement of bandgap energies by examining the onset of inelastic energy loss in core-level atomic spectra using X-ray photoelectron spectroscopy is proved to be valid for determining the bandgap of (AlGa)2O3 films as it is in good agreement with the bandgap values from transmittance spectra. The measured bandgap of (AlGa)2O3 films increases continuously with the Al content covering the whole Al content range from about 5 to 7 eV, indicating PLD is a promising growth technology for growing bandgap tunable (AlGa)2O3 films.
Selective adhesion of microorganisms to the ductular epithelium of the bovine mammary gland (1975)

Streptococcus agalactiae, Streptococcus faecalis, Staphylococcus aureus, Escherichia coli, and Corynebacterium bovis were examined for their ability to adhere to the ductular epithelial cells of the bovine udder. S. agalactiae and S. aureus adhered readily and in large numbers, whereas the other organisms adhered poorly or not at all. The organisms showing the ability to adhere are those which frequently cause mastitis. These data suggest that selective adherence to the ductular epithelium may be the first stage in the pathogenesis of streptococcal and staphylococcal mastitis.
Retroviral Elements and Their Hosts: Insertional Mutagenesis in the Mouse Germ Line (2006)

The inbred mouse is an invaluable model for human biology and disease. Nevertheless, when considering genetic mechanisms of variation and disease, it is important to appreciate the significant differences in the spectra of spontaneous mutations that distinguish these species. While insertions of transposable elements are responsible for only approximately 0.1% of de novo mutations in humans, the figure is 100-fold higher in the laboratory mouse. This striking difference is largely due to the ongoing activity of mouse endogenous retroviral elements. Here we briefly review mouse endogenous retroviruses (ERVs) and their influence on gene expression, analyze mechanisms of interaction between ERVs and the host cell, and summarize the variety of mutations caused by ERV insertions. The prevalence of mouse ERV activity indicates that the genome of the laboratory mouse is presently behind in the "arms race" against invasion.
SIGNAL ADJUSTMENT OF VIBROSEIS AND IMPULSIVE SOURCE DATA* (1987)

A bstract In certain areas continuous Vibroseis profiling is not possible due to varying terrain conditions. Impulsive sources can be used to maintain continuous coverage. While this technique keeps the coverage at the desired level, for the processing of the actual data there is the problem of using different sources resulting in different source wavelets. In addition, the effect of the free surface is different for these two energy sources. The approach to these problems consists of a minimum‐phase transformation of the two‐sided Vibroseis data by removal of the anticipation component of the autocorrelation of the filtered sweep and a minimum‐phase transformation of the impulsive source data by replacement of the recording filter operator with its minimum‐phase correspondent. Therefore, after this transformation, both datasets show causal wavelets and a conventional deconvolution (spike or predictive) may be used. After stacking, a zero‐phase transformation can be performed resulting in traces well suited for computing pseudo‐acoustic impedance logs or for application of complex seismic trace analysis. The solution is also applicable to pure Vibroseis data, thereby eliminating the need for a special Vibroseis deconvolution. The processing steps described above are demonstrated on synthetic and actual data. The transformation operators used are two‐sided recursive (TSR) shaping filters. After application of the above adjustment procedure, remaining signal distortions can be removed by modifying only the phase spectrum or both the amplitude and phase spectra. It can be shown that an arbitrary distortion defined in the frequency domain, i.e., a distortion of the amplitude and phase spectrum, is noticeable in the time section as a two‐sided signal.
Corticospinal Motor Neurons and Related Subcerebral Projection Neurons Undergo Early and Specific Neurodegeneration in hSOD1<sup>G93A</sup>Transgenic ALS Mice (2011)

Amyotrophic lateral sclerosis (ALS) is characterized by predominant vulnerability and central degeneration of both corticospinal/corticobulbar motor neurons (CSMN; "upper motor neurons") in cerebral cortex, and spinal/bulbar motor neurons (SMN; "lower motor neurons") in spinal cord and brainstem. Increasing evidence indicates broader cerebral cortex pathology in cognitive, sensory, and association systems in select cases. It remains unclear whether widely accepted transgenic ALS models, in particular hSOD1(G93A) mice, undergo degeneration of CSMN and molecularly/developmentally closely related populations of nonmotor projection neurons [e.g., other subcerebral projection neurons (SCPN)], and whether potential CSMN/SCPN degeneration is specific and early. This relative lack of knowledge regarding upper motor neuron pathology in these ALS model mice has hindered both molecular-pathophysiologic understanding of ALS and their use toward potential CSMN therapeutic approaches. Here, using a combination of anatomic, cellular, transgenic labeling, and newly available neuronal subtype-specific molecular analyses, we identify that CSMN and related nonmotor SCPN specifically and progressively degenerate in hSOD1(G93A) mice. Degeneration starts quite early and presymptomatically, by postnatal day 30. Other neocortical layers, cortical interneurons, and other projection neuron populations, even within layer V, are not similarly affected. Nonneuronal pathology in neocortex (activated astroglia and microglia) is consistent with findings in human ALS cortex and in affected mouse and human spinal cord. These results indicate previously unknown neuron type-specific vulnerability of CSMN/sensory and association SCPN, and identify that characteristic dual CSMN and SMN degeneration is conserved in hSOD1(G93A) mice. These results provide a foundation for detailed investigation of CSMN/SCPN vulnerability and toward potential CSMN therapeutics in ALS.
Local Simvastatin Effects on Mandibular Bone Growth and Inflammation (2005)

Reducing the simvastatin dose from 2.2 to 0.5 mg reduced inflammation to a more clinically acceptable level without sacrificing bone-growth potential, but COX-associated inflammation appears to be necessary for in vivo bone growth.
Metal Oxides for Dye‐Sensitized Solar Cells (2009)

The incessant demand for energy forces us to seek it from sustainable resources; and concerns on environment demands that resources should be clean as well. Metal oxide semiconductors, which are stable and environment friendly materials, are used in photovoltaics either as photoelectrode in dye solar cells (DSCs) or to build metal oxide p – n junctions. Progress made in utilization of metal oxides for photoelectrode in DSC is reviewed in this article. Basic operational principle and factors that control the photoconversion efficiency of DSC are briefly outlined. The d ‐block binary metal oxides viz. TiO 2 , ZnO, and Nb 2 O 5 are the best candidates as photoelectrode due to the dissimilarity in orbitals constituting their conduction band and valence band. This dissimilarity decreases the probability of charge recombination and enhances the carrier lifetime in these materials. Ternary metal oxide such as Zn 2 SnO 4 could also be a promising material for photovoltaic application. Various morphologies such as nanoparticles, nanowires, nanotubes, and nanofibers have been explored to enhance the energy conversion efficiency of DSCs. The TiO 2 served as a model system to study the properties and factors that control the photoconversion efficiency of DSCs; therefore, such discussion is limited to TiO 2 in this article. The electron transport occurs through nanocrystalline TiO 2 through trapping and detrapping events; however, exact nature of these trap states are not thoroughly quantified. Research efforts are required not only to quantify the trap states in mesoporous metal oxides but new mesoporous architectures also to increase the conversion efficiency of metal oxide‐based photovoltaics.
The antibacterial mode of action of allitridi for its potential use as a therapeutic agent against<i>Helicobacter  pylori</i> infection (2009)

Eradication of Helicobacter pylori with traditional therapy often fails in clinical treatment. As a result, a novel efficacious therapeutic agent is strongly needed. Allitridi, a proprietary garlic derivative, has been successfully used to treat both systemic fungal and bacterial infections in China. Our previous study has shown a dose-dependent inhibitory effect of allitridi on H. pylori growth. However, the antibacterial mode of action of allitridi is still unclear. Proteomic analysis was used to study the global protein alterations induced by allitridi. A total of 21 protein spots were identified to be differentially expressed. Our results indicated that the bacteriostatic mechanism of allitridi in H. pylori can be attributed to its multitarget inhibitory effects in energy metabolism and biosynthesis including amino acid biosynthesis, protein synthesis, mRNA synthesis and fatty acid biosynthesis. Allitridi can also disturb the expression of antioxidant proteins and decrease the production of virulence factors. Western blot analysis showed that allitridi at subinhibitory concentrations can potently suppress the production of CagA and VacA. Our investigations on the antibacterial mode of action of allitridi provide an insight into the potential use of allitridi as a therapeutic agent against H. pylori infection.
Introduction to radar cross-section measurements (1965)

This paper is intended to serve both as an introduction to radar cross-section measurements and as an introduction to the several measurement papers that follow in this issue. We discuss the contribution that experimental work makes to theoretical studies. The history of cross-section measurements is reviewed. Some terms are defined, and the major measurement problems are discussed. It is pointed out that the various range geometries and measurement techniques in use today were based on the approach used to solve the basic measurement problems. Some details are given of the more popular present-day measurement systems, i.e., CW, pulsed, FM-CW, Doppler, and the standing-wave ratio method.

Structural and Cell-associated Proteins of Lassa Virus (1983)

Lassa virus was purified from culture fluids of infected CV-1 monkey kidney cells and its structural proteins analysed by polyacrylamide gel electrophoresis. Stained gels showed a typical arenavirus profile, with a prominent protein of molecular weight 60000, corresponding to the nucleocapsid protein N, and two faint broad bands with molecular weights of 45000 and 38000, the envelope glycoproteins G1 and G2. G1 and G2 were shown to be glycosylated by their ability to bind concanavalin A to nitrocellulose transfers of the separated proteins ('Western blots'). N and G2 bound antibody from guinea-pig or human convalescent sera but G1 was inactive, presumably as a result of denaturation. This technique also revealed other apparently virus-specific minor bands with molecular weights of 76000 and 68000. When Western blots of proteins of infected cells which had been lysed in SDS were probed with anti-Lassa virus serum or stained for glycoproteins, four virus-specific bands were apparent: the N, G1 and G2 proteins seen in purified virus, and a glycoprotein of molecular weight 72000 which probably corresponds to the envelope protein precursor (GPC) seen in other arenavirus systems. Immunoprecipitates from infected CV-1 cells labelled with [35S]methionine contained three major virus-specific proteins: the nucleocapsid protein N and proteins of 36000 and 24000 molecular weight (designated fN1 and fN2). Similar immunoprecipitates from Vero cells contained fN1 and fN2 and only very low levels of N. The polypeptides fN1 and fN2 are most probably fragments of N, since Western blots probed with anti-Lassa virus serum showed that lysis of cells in non-ionic detergent rather than SDS results in the appearance of fN2 with concomitant reduction or disappearance of N. These fragments do not exist in the intact cell, but are found as a consequence of rather specific proteolysis upon disruption under non-denaturing conditions. The proteolytic activity responsible was refractory to inhibition by phenylmethylsulphonyl fluoride, aprotinin, pepstatin A or sodium bisulphite, and was more active in Vero than in CV-1 cells.
Image Editing with Intelligent Paint (2002)

Intelligent Paint provides a new tool for interactively selecting image objects or regions of interest, while simultaneously applying filters or effects directly to the selection(s). By coupling adaptive cost-ordered region growing with the high-level visual expertise of the user to indicate which objects are of interest, we are able to accurately select and edit complex, non-homogeneous objects in only a few seconds using simple mouse input gestures. Prior to selection, the image is oversegmented using a watershed (tobogganing) algorithm. Watershed catchment basins are assembled into an hierarchical image partition by grouping basins using the student’s t-distribution. Grouped basins, referred to as TRAPs (Tobogganed Region Accumulation Plateaus), reasonably capture sub-object detail. Object selection is accomplished by user-steered, adaptive, cost-ordered collection of TRAPs. Tinting or application of filters during object selection provides immediate visual feedback as to what is being selected as well as the suitability of the chosen digital effect. Intelligent Paint selection compares favorably with popular commercial tools in terms of efficiency, accuracy and reproducibility with the added benefit of on-the-fly filtering, while raising the granularity of image editing from the pixel to the object-level. Novel tools for object-centered image editing such as Intelligent Eraser and Intelligent Clone tools are also possible with this technique.
A simplified and efficient method for treating varicose veins. (1979)

Stripping the saphenous vein and manual excision of varicose veins has been the popular operative treatment for many years. During this 2- to 4-hour procedure, the patient must be rotated from the supine to the prone position in order to excise the collateral veins. These maneuvers are time-consuming and result in contamination, dozens of unsightly scars, and incomplete destruction of many of the small tortuous varicosities. In 705 patients we have substituted limited excision when possible and high-frequency cautery methods to destroy the venous tributaries. Cauterization, accomplished by introducing a probe subcutaneously through a 2 mm skin incision which requires no sutures for closure, affords excellent treatment for the troublesome smaller tortuous veins. The recurrence rate depends on the primary cause of the varicosities and is roughly the same in both types of operative procedures. The advantages of the latter procedure are shorter operating and anesthesia times, minimal infection rate, substantially less hospital time and cost, and essentially no cosmetic defects.
Traction Drive CVT Technologies for Aircraft Equipment (2007)

In 1996, research activities on traction drive CVT technologies was commenced in order to apply them to aircraft equipment. Extensive efforts have been conducted to overcome various technical barriers such as weight and severe environmental conditions with employing high speed traction drive technology, a split power mechanism and a sensorless control method using “Observer”. Using these technologies, a all new concept IDG called “T-IDG®” has been developed.
Radiative energy and momentum transfer for various spherical shapes: A single sphere, a bubble, a spherical shell, and a coated sphere (2015)

We use fluctuational electrodynamics to determine spectral emissivity and van der Waals contribution to surface energy for various spherical shapes, such as a sphere, a bubble, a spherical shell, and a coated sphere, in a homogeneous and isotropic medium. The dyadic Green's function formalism of radiative energy and fluctuation-induced van der Waals stress for different spherical configurations has been developed. We show (1) emission spectra of micro- and nano-sized single and coated spheres display several emissivity sharp peaks as the size of object reduces and (2) surface energy becomes size dependent due to van der Waals phenomena when size of object is reduced to a nanoscopic length scale.
Chemical investigation of Indian plants. Part VII (1973)

Large-Scale Coarse-to-Fine Object Retrieval Ontology and Deep Local Multitask Learning (2019)

Object retrieval plays an increasingly important role in video surveillance, digital marketing, e-commerce, etc. It is facing challenges such as large-scale datasets, imbalanced data, viewpoint, cluster background, and fine-grained details (attributes). This paper has proposed a model to integrate object ontology, a local multitask deep neural network (local MDNN), and an imbalanced data solver to take advantages and overcome the shortcomings of deep learning network models to improve the performance of the large-scale object retrieval system from the coarse-grained level (categories) to the fine-grained level (attributes). Our proposed coarse-to-fine object retrieval (CFOR) system can be robust and resistant to the challenges listed above. To the best of our knowledge, the new main point of our CFOR system is the power of mutual support of object ontology, a local MDNN, and an imbalanced data solver in a unified system. Object ontology supports the exploitation of the inner-group correlations to improve the system performance in category classification, attribute classification, and conducting training flow and retrieval flow to save computational costs in the training stage and retrieval stage on large-scale datasets, respectively. A local MDNN supports linking object ontology to the raw data, and an imbalanced data solver based on Matthews' correlation coefficient (MCC) addresses that the imbalance of data has contributed effectively to increasing the quality of object ontology realization without adjusting network architecture and data augmentation. In order to evaluate the performance of the CFOR system, we experimented on the DeepFashion dataset. This paper has shown that our local MDNN framework based on the pretrained NASNet architecture has achieved better performance (14.2% higher in recall rate) compared to single-task learning (STL) in the attribute learning task; it has also shown that our model with an imbalanced data solver has achieved better performance (5.14% higher in recall rate for fewer data attributes) compared to models that do not take this into account. Moreover, MAP@30 hovers 0.815 in retrieval on an average of 35 imbalanced fashion attributes.
Congenital Bronchial Hypoplasia in Calves (1966)

The literature on anomalies of the lung in domestic animals was reviewed. Three cases of congenitally anomalous lungs in calves were described. Two were cases of accessory lungs, and one was a case of hypoplasia of the bronchi affecting both normally situated lungs of a calf. Hypoplastic bronchi were also present in the two cases of accessory lungs. The pathogenesis of these anomalies was discussed in the light of what is known of the embryology of the porcine lung. The basic defect was considered in all three cases to be hypoplasia of the bronchi, which can occur either in conjunction with acessory lungs or otherwise.
LOADING AND ELUTION CHARACTERISTICS OF SOME NATURAL AND SYNTHETIC ZEOLITES (1962)

The cation exchange characteristics of several commercially available zeolites were evaluated, Equilibrium loading characteristics and exchange capacities were determined experimentally in the binary systems cesium-lithium, cesium-- sodium, cesium--potassium, cesium-Tubidium, cesium -- hydrogen, cesium-- ammonium, strontium-- magnesium, strontium-- calcium, strontium-- barium, and strontium-- hydrogen for several zeolites. Exchangeable cation fractions in the equilibrium solutions were varied from 0.2 to 0.00001, while the total normality of the system constituents was held constant. Results were plotted as equivalent fraction of the traced cation on the zeolite at equilibrium vs. the fraction of traced cation remaining in the equilibrium solution. If an influent composition is known, and falls in the system listed above, zeolite column loading may be read directly in univalent-univalent or divalent-divalent systems. However, in the strontium-sodium or strontium-- hydrogen systems, a k value must be used because squared terms appear in the equilibrium expression as follows: 2 Na- zeolite plus or minus Sr-solution in equilibrium 2 Nasolution + Sr-zeolite, or k = (Sr-zeolite)(Na-solution)/ (Na-zeolite)2(Sr-solution). The k for a given cation is a function of zeolite loading with that cation. Several column 50% loading capacities were determined to randomly test the validity of the above curves to predict column capacities, Several columns loaded with known amounts of cesium and strontium radioisotopes were heated to 800 deg C for 24 hours to simulate a zeolite packaging dehydration cycle. Losses of cesium and strontium activity during the 24-hr period were determined. Elution of the remaining activity on the columns was accomplished with various eluting agents including dilute HNO/sub 3/, NH/sub 4/NO/sub 3/, CaCl/sub 2/ and La(NO/su b 3/)/sub 3/, and elution curves were calculated.

ON THE NATURE OF <i>CIS</i>-ACTING REGULATORY PROTEINS AND GENETIC ORGANIZATION IN BACTERIOPHAGE: THE EXAMPLE OF GENE <i>Q</i> OF BACTERIOPHAGE Λ (1976)

We note the existence of a "partially cis-acting" regulatory protein of bacteriophage lambda: the product of the phage Q gene. We suggest that there may be a complete spectrum from "all cis" to "all trans" for such regulatory proteins. This behavior might arise because a DNA-binding protein either acts at a nearby (cis) site soon after synthesis or becomes "lost" for its trans activity on another genome through nonspecific interactions with DNA. Our proposed explanation provides one evolutionary basis for the linkage of genes for regulatory proteins and the sites at which such proteins act; it also suggests a possible rationale for the "metabolic instability" of certain regulatory proteins.
Cholesterol: Vitamin C Controls Its Transformation to Bile Acids (1973)

Cholesterol accumulates in the blood serum and in the liver of guinea pigs with chronic latent vitamin C deficiency. The reason for this is the decreased rate of transformation of cholesterol to bile acids in the liver of animals deficient in vitamin C. A significant direct correlation exists between the vitamin C concentration in the liver and the rate of cholesterol transformation to bile acids.
