A stain for demonstrating Helicobacter pylori in gastric biopsies. (2001)

Helicobacter pylori continues to be a significant health care problem. It is associated with a variety of stomach disorders such as gastritis, gastric ulcer disease, gastric carcinoma and B-cell gastric lymphoma. One common method diagnosing an infection by this bacterium is microscopic examination of routine processed gastric or duodenal biopsies. With this type of specimen, it is necessary to demonstrate visually the presence of H. pylori using an appropriate staining technique. This paper presents a simple staining technique for demonstrating H. pylori in gastric biopsy specimens using carbol fuchsin staining against a contrasting background of light green.
The strategic impact of IT on the retail financial services industry (2002)

The paper is concerned with the strategic impact of information technology on the retail financial services industry. Today, in deregulated markets notably in Europe and especially the UK, traditionally separate industry sectors such as banking, insurance, housing finance and brokerage have become increasingly integrated since the late 1980's. In the USA and Japan regulation has prevented all these historically segregated sectors from integrating although the same patterns observable in Europe have attempted to emerge. In addition, around the world institutions such as retailers, brokerage houses and the like, not subject to the constraints of those officially licensed institutions such as banks and insurance companies, have been free to add financial services to their product portfolios subject to certain constraints. As a result it is these new entrants which have often pioneered the development of new ways of providing traditional services with lower levels of cost but offering superior consumer quality. These innovations have almost invariably been driven by information technology.
Evidence for a primary abnormality of thecal cell steroidogenesis in the polycystic ovary syndrome (1997)

These findings provide further evidence in favour of an intrinsic abnormality of thecal cell steroidogenesis in the polycystic ovary.
Presence of the Hemochromatosis S65C Mutation Leads to Failure of Amplification in a Multiplex C282Y/H63D PCR (2007)

Hemochromatosis is an autosomal recessive disorder of iron metabolism affecting 0.2%–0.5% of white populations. Approximately 90% of affected individuals are homozygous for the C282Y mutation, but the H63D and S65C mutations are also of interest.

Various molecular diagnostic methods for detection of these mutations have been described, including a multiplex PCR from Stott et al. (1) that simultaneously detects the C282Y and H63D mutations. In this method, PCR-mediated site-directed mutagenesis is used to create a Bbr PI restriction site in the wild-type C282Y and H63D products. To detect the C282Y mutation and the H63D mutation, respectively, 1 specific mismatch in the forward …
Development of Physical and Optical Methods for In-shell Brazil Nuts Sorting and Aflatoxin Reduction (2009)

Physical methods for mechanically in-shell Brazil nut sorting by color, size, density and inner deterioration weredeveloped to assess nut quality and reduce aflatoxin contamination. Nuts were able to be sorted by color utilizing thestandard shell chromaticity components L*, a* and b* at ranges of 31.51 to 48.64, 4.09 to 10.07 and 11.90 to 22.95,respectively. It produced a homogeneous color batch and segregated the off-standard ones (darkest, lightest and stained).By size sorting utilizing three oval sectioned trays with the following dimensions 40x25, 35x23 and 20x19.5 mm[length x width] and vibration, nuts were sorted into three sizes Groups: I, II and III for large, medium and small,respectively. Through density sorting the light nuts (shell/nut

Molecular genetics of APUDomas (1993)

It is tempting to speculate that genetic studies of the human APUDomas, particularly those of a hereditary nature, may ultimately provide valuable clues to the molecular basis of malignant transformation in cells of all types, uncover the mechanisms responsible for tumor progression, and perhaps decipher the signals important in the differentiation of normal neural crest-derived tissue. Generally, several strategies have been used in the genetic analysis of these tumors with success. These include (1) cytogenetic examination of recurring chromosomal abnormalities in hopes of pinpointing critical neighboring growth regulatory sequences important in tumor evolution, (2) identification of dominant acting oncogenes in tumor cells, (3) search for recessive inactivated suppressor genes that may regulate cell growth by analyzing tumors for loss of heterozygosity (LOH), and (4) genetic linkage studies of kindreds affected with familial APUDomas to identify and subsequently characterize the predisposition gene using a positional or functional cloning approach. The results of these strategies as they have been employed in the investigation of cutaneous malignant melanoma (CMM), the dysplastic nevus syndrome (DNS), and the multiple endocrine neoplasia (MEN) syndromes are summarized.
Latchup criteria in insulated gate p-n-p-n structures (1985)

Latchup in insulated-gate p-n-p-n structures may be due either to the well-known thyristor action or to a regenerative feedback originating from substrate bias in the MOS gate. Simple models are presented to interpret and to predict both latching modes. It is shown that these two latching modes may occur consecutively as the current level rises, and that the device may, therefore, exhibit three distinct regions of forward operation. Experiments on special test devices in which the p-base region can be accessed externally support the theory well.

Metabolic changes in free amino acids of bean leaves exposed to ozone. (1967)

Leaves of bean, tobacco, beet, corn, barley, or rye that are visibly damaged by ozone accumulate several common free amino acids. Shorter periods of ozonation, which do not cause visible damage to the leaves, produce more specific metabolic responses: ..gamma..-amino-n-butyric acid (GABA) and alanine increase, and glutamic acid decreases. To our knowledge this is the first report on changes in amino acid metabolism effected by ozone fumigation. The pattern of amino acid labeling and fixation of CO/sub 2/ by ozonated plants suggests a complex process of enhanced decarboxylation of glutamic acid, and inhibited photosynthesis and protein synthesis. These effects could result from the oxidation of essential sulfhydryl groups and increased membrane permeability. 12 references, 2 tables.
The Correction of Equinus Deformity in Cerebral Palsy (1958)

Orthopaedic procedures for the correction of equinus deformity are effective measures in the treatment of spastic cerebral palsy. The best operative procedure for the correction of fixed equinus deformity in our series was a sliding lengthening of the heel cord. Adequate postoperative management of these patients is essential in order to obtain a good result. Long-term support out of equinus position at night during the growing period, and an exercise regimen to develop balanced muscle function between agonist and antagonist are essential to an effective result. Whereas stabilization of the foot is an effective measure in correcting varus or valgus deformity and simplifying the control of the foot in older individuals, it should not be used as a procedure to correct severe equinus deformity.

Pumilio/fem-3 mRNA binding factor proteins are characterized by a sequence-specific RNA-binding domain. This unique single-stranded RNA recognition module, whose sequence specificity can be reprogrammed, has been fused with functional modules to engineer protein factors with various functions. We summarize the advances made with respect to developing RNA regulatory tools, as well as opportunities for the future.
Solar limb brightening in submillimeter wavelengths (1976)

Differential two-beam scans of the sun in submillimeter wavelengths (350 microns to 1 millimeter) indicate limb brightening approaching 1 percent when the cosine of the angle from the normal equals 0.60. The observations also show considerable chromospheric structure, both in active and quiet regions, but with less relative amplitude than at millimeter and centimeter wavelengths. The limited angular resolution of the observing system, together with photometric errors due to fluctuating atmospheric transparency, make the brightness profile of the extreme limb uncertain. The observed degree of limb brightening is considerably less than that consistent with spherically symmetric model atmospheres based on continuum brightness-temperature measurements. The suppression of limb brightening suggests the existence of irregular granular structure with both horizontal and vertical characteristic sizes of the order of 1500 km. High-resolution images in the wings of the K-line show granular structure of about this horizontal scale.
Two Test Specimens for Determining the Interfacial Fracture Toughness in Flip-Chip Assemblies (1998)

Two test specimens are developed to measure interfacial fracture toughness in flip-chip assemblies. The specimens consist of three layers: silicon chip, underfill, and circuit board. Two symmetric edge cracks are embedded along the interface, either between the chip and the underfill or between the underfill and the circuit board. The specimens are subjected to four-point-bend loading and critical loads are obtained. Analytical solutions for energy release rate have been derived for these two specimens and used to obtain the toughness from the measured critical loads. These specimens have been used to evaluate material combinations of chip passivation, underfill and solder mask for desired interfacial strength.
Analysis of the occurrence of promoter-sites in DNA (1986)

We show that the occurrence and homology score (1) of promoter-sites in DNA depends upon the base composition of the DNA. We used simple probability theory to calculate the mean homology score expected for all promoter-sites that had a specific match in the canonical hexamers. By using the square root of this mean score as a measure of significance, we objectively classify all promoter-sites which are reported. We tested the theoretical approach in two ways. First, we used the program (PROMSEARCH) to analyze approximately 150,000 base pairs of random sequence DNA with different base compositions and we found excellent agreement with the theoretical predictions. Our second test was the analysis of a number of sequences drawn from the GENBANK DNA sequence database. We have analyzed 20 bacterial and bacteriophage sequences, which consisted of at least one operon, for promoter-sites. We found no absolute preference for promoter-sites within noncoding regions. We show the results of analyzing the phages lambda, T7 and fd, and the E. coli lac operon. The major known promoters in these sequences were all found correctly. We discuss the question of the location of a number of minor promoter-sites and show how PROMSEARCH can be used to help identify the correct location of the promoter. This approach can be applied to the search for any DNA site and should allow greater objectivity when comparing DNA sequences for meaningful subsequences.
Multi-GeV Electron Beams from Capillary-Discharge-Guided Subpetawatt Laser Pulses in the Self-Trapping Regime (2014)

Multi-GeV electron beams with energy up to 4.2 GeV, 6% rms energy spread, 6 pC charge, and 0.3 mrad rms divergence have been produced from a 9-cm-long capillary discharge waveguide with a plasma density of ≈7×10¹⁷ cm⁻³, powered by laser pulses with peak power up to 0.3 PW. Preformed plasma waveguides allow the use of lower laser power compared to unguided plasma structures to achieve the same electron beam energy. A detailed comparison between experiment and simulation indicates the sensitivity in this regime of the guiding and acceleration in the plasma structure to input intensity, density, and near-field laser mode profile.

ATD-specific network management functions and TMN architecture (1992)

The paper deals with the ATM (asynchronous transfer mode) - specific functions of source policing and connection acceptance control and their relationship to network management. The aspects of ATM-specific network management are based on the results achieved by the RACE project R1022, ‘Technology for ATD’. It is shown how these functions can be implemented according to the TMN (telecommunications management network) architecture suggested by the RACE project GUIDELINE (R1003). The interaction between these functions and other network management functions is discussed and the interaction of these functions with the management layers is presented in a way which is not dependent on the specific algorithms used for source policing and connection acceptance control.
Face Aging with Identity-Preserved Conditional Generative Adversarial Networks (2018)

Face aging is of great importance for cross-age recognition and entertainment related applications. However, the lack of labeled faces of the same person across a long age range makes it challenging. Because of different aging speed of different persons, our face aging approach aims at synthesizing a face whose target age lies in some given age group instead of synthesizing a face with a certain age. By grouping faces with target age together, the objective of face aging is equivalent to transferring aging patterns of faces within the target age group to the face whose aged face is to be synthesized. Meanwhile, the synthesized face should have the same identity with the input face. Thus we propose an Identity-Preserved Conditional Generative Adversarial Networks (IPCGANs) framework, in which a Conditional Generative Adversarial Networks module functions as generating a face that looks realistic and is with the target age, an identity-preserved module preserves the identity information and an age classifier forces the generated face with the target age. Both qualitative and quantitative experiments show that our method can generate more realistic faces in terms of image quality, person identity and age consistency with human observations.

The Evaporative Function of Cockroach Hygroreceptors (2013)

Insect hygroreceptors associate as antagonistic pairs of a moist cell and a dry cell together with a cold cell in small cuticular sensilla on the antennae. The mechanisms by which the atmospheric humidity stimulates the hygroreceptive cells remain elusive. Three models for humidity transduction have been proposed in which hygroreceptors operate either as mechanical hygrometers, evaporation detectors or psychrometers. Mechanical hygrometers are assumed to respond to the relative humidity, evaporation detectors to the saturation deficit and psychrometers to the temperature depression (the difference between wet-bulb and dry-bulb temperatures). The models refer to different ways of expressing humidity. This also means, however, that at different temperatures these different types of hygroreceptors indicate very different humidity conditions. The present study tested the adequacy of the three models on the cockroach's moist and dry cells by determining whether the specific predictions about the temperature-dependence of the humidity responses are indeed observed. While in previous studies stimulation consisted of rapid step-like humidity changes, here we changed humidity slowly and continuously up and down in a sinusoidal fashion. The low rates of change made it possible to measure instantaneous humidity values based on UV-absorption and to assign these values to the hygroreceptive sensillum. The moist cell fitted neither the mechanical hygrometer nor the evaporation detector model: the temperature dependence of its humidity responses could not be attributed to relative humidity or to saturation deficit, respectively. The psychrometer model, however, was verified by the close relationships of the moist cell's response with the wet-bulb temperature and the dry cell's response with the dry-bulb temperature. Thus, the hygroreceptors respond to evaporation and the resulting cooling due to the wetness or dryness of the air. The drier the ambient air (absolutely) and the higher the temperature, the greater the evaporative temperature depression and the power to desiccate.
InGaZnO metal‐base transistor with high current gain (2014)

The fabrication of metal‐base transistors (MBTs) based on InGaZnO at room temperature is reported for the first time. With a suitable oxygen doping to the sputtering‐deposited InGaZnO film and an HfSiO interlayer, improved diode performances with enhanced Schottky barrier heights of 0.70 and 0.66 eV are obtained for the base/collector (Ti/InGaZnO) and base/emitter (Au/HfSiO/InGaZnO) junctions, respectively. InGaZnO MBT using a Ti(10 nm)/Au(10 m)/HfSiO(5 nm) dual metal base shows a high common‐emitter current gain ( β ) 840–310 at V CE = 2 V and I B ranging from 1 to 10 nA.
Structures for amyloid fibrils (2005)

Alzheimer's disease and Creutzfeldt-Jakob disease are the best-known examples of a group of diseases known as the amyloidoses. They are characterized by the extracellular deposition of toxic, insoluble amyloid fibrils. Knowledge of the structure of these fibrils is essential for understanding the process of pathology of the amyloidoses and for the rational design of drugs to inhibit or reverse amyloid formation. Structural models have been built using information from a wide variety of techniques, including X-ray diffraction, electron microscopy, solid state NMR and EPR. Recent advances have been made in understanding the architecture of the amyloid fibril. Here, we describe and compare postulated structural models for the mature amyloid fibril and discuss how the ordered structure of amyloid contributes to its stability.
Synthesis, Characterization and Surface Active Properties of Imidazolinium Surfactant Derived from Oleic Acid and Diethylenetriamine (2008)

Abstract This paper describes an efficient method for the synthesis of long chain alkylamido imidazolines by the reaction of diethylenetriamine and oleic acid under non-solvent microwave irradiation using calcium oxide as support and their comparison with conventional thermal condensation process. Synthesized imidazolines were then quaternized by using dimethylsulfate as a quaternizing agent and isopropanol as a solvent, to produce cationic imidazolinium salts which were evaluated for yield and cationic content. The instrumental techniques, viz. FT-IR and 1 H-NMR verified the formation of imidazolines and its subsequent quaternization. The surface active and performance properties of cationic imidazolines in terms of c.m.c., surface tension, dispersability, emulsion stability, softening, rewettability and detergency were also reported.
