A conditional yeast mutant deficient in mRNA transport from nucleus to cytoplasm. (1992)

Transport of mRNA from nucleus to cytoplasm is critical for eukaryotic gene expression; however, the mechanism of export is unknown. Selection and screening procedures have therefore been used to obtain a family of temperature-sensitive conditional mutants of Saccharomyces cerevisiae that accumulate poly(A)+ RNA in the nucleus when incubated at 37 degrees C, as judged by in situ hybridization. In one such mRNA transport mutant, mtr1-1, RNA synthesis continues, the export of poly(A)+ RNA is inhibited, intranuclear poly(A)+ is remarkably stable, and protein synthesis gradually stops. Thus, there is no tight coupling between RNA synthesis and export. The export lesion is reversible. Although mRNA export is clearly not a default option, neither inhibition of protein synthesis, inhibition of mRNA splicing, nor inhibition of poly(A)-binding protein function blocks export of the average poly(A)+, as judged by in situ hybridization. Further analysis of the family of mtr mutants should help map the path of RNA transport.

of the fused fluoride, the fused fluoride temperature, the HF fiow rate, the metallurgical characteristics of the material being dissolved, and the presence of other metals. The low dissolution rate of 0.00i mil/hr observed for nickel suggests that it may be suitable as a material of construction for reaction vessels. (auth)
Craft Specialists at Moche: Organization, Affiliations, and Identities (2010)

Abstract This article examines the organization of specialized craft production at the urban site of Moche, known as the capital of the Southern Moche state. Recent excavations in workshop contexts revealed that the urban population of Moche was in part composed of ceramists, metallurgists, and lapidaries. These craft specialists played a significant role in the economic, political, and religious spheres of the Moche polity. Data obtained during excavations of workshops and domestic compounds are used to analyze the context, scale, and intensity of craft production, taking into account the nature of the goods produced and the identity of consumers. The discussion also considers the integration of craft specialists into the daily life and social structure at the site of Moche. Excavations showed that while urban craft specialists were not independent, they were not tightly controlled by a centralized ruling elite. They produced symbolic goods in various small to middle-scale workshops integrated into residential units, under the direct authority of urban leaders taking advantage of this particular organization of semi-attached craft production in various status-building strategies.
DNA Sequence Error Rates in Genbank Records Estimated using the Mouse Genome as a Reference (2004)

We estimate DNA sequence error rates in Genbank records containing protein-coding and non-coding DNA sequences by comparing sequences of the inbred mouse strain C57BL/6J, sequenced as part of the mouse genome project and independently by other laboratories. C57BL/6J was produced by more than 100 generations of brother-sister mating, and can be assumed to be virtually free of residual polymorphism and mutational variation, so differences between independent sequences can be attributed to error. The estimated single nucleotide error rate for coding DNA is 0.10% (SE 0.012%), which is substantially lower than previous estimates for error rates in Genbank accessions. The estimated single nucleotide error rate for intronic DNA sequences (0.22%; SE 0.051%) is significantly higher than the rate for coding DNA. Since error rates for the mouse genome sequence are very low, the vast majority of the errors we detected are likely to be in individual Genbank accessions. The frequency of insertion-deletion (indel) errors in non-coding DNA approaches that of single nucleotide errors in non-coding DNA, whereas indel errors are uncommon in coding sequences.
Sleep disorders in pregnancy (2003)

In conclusion, sleep disturbances are common during pregnancy though the full extent of this relation remains undefined. Large, multi-center, prospective studies are needed for better understanding.
A three-phase parallel active power filter operating with PCC voltage compensation using reactive power (2002)

The performance and dynamic characteristics of a three-phase parallel active power filter with point of common coupling (PCC) voltage compensation is presented and analyzed in this paper. The proposed scheme in this paper employs a PWM voltage-source inverter and has two operation modes. First, it operates as a conventional active filter with reactive power compensation while PCC voltage is in a certain range. Second, it operates as a voltage compensator while PCC voltage is out of a certain range. Finally, the validity of this scheme is investigated through analysis of simulation and experimental results for a prototype active power filter system rated at 10 kVA.
Differential effects of atenolol and enalapril on memory during treatment for essential hypertension. (1986)

A randomized single-blind study was designed to compare the performance on memory tests requiring recall of information relevant to everyday life of two groups of hypertensive patients. One group of 13 patients were taking a beta-adrenoceptor blocker (atenolol) and the other group of 12 patients received the angiotensin-converting enzyme inhibitor (enalapril). The results suggested that when compared with placebo the group of patients treated with enalapril showed no changes in memory function, whilst there was a mild, but consistent deficit in the group taking atenolol.
Adaptive Channel Equalizer for Wireless Access in Vehicular Environments (2007)

Dedicated short range communication (DSRC) is the key component in intelligent transportation systems (ITS). The goal of this technology is to help driver and passengers getting multimedia services via wireless communication equipment during the movement of vehicle, so as to improve the traffic safety and enhance the transportation efficiency. The paper is focus on the DSRC baseband technical analysis and the application development. Based on the WLAN 802.11a architecture, we develop a new adaptive channel estimation algorithm that uses two kinds of feedback tracking and pilot aid to enhance wireless access ability in vehicular environments.
Circularly symmetric watermark embedding in 2-D DFT domain (2001)

In this paper, a method for digital image watermarking is described that is resistant to geometric transformations. A private key, which allows a very large number of watermarks, determines the watermark, which is embedded on a ring in the DFT domain. The watermark possesses circular symmetry. Correlation is used for watermark detection. The original image is not required in detection. The proposed method is resistant to JPEG compression, filtering, noise addition, scaling, translation, cropping, rotation, printing and rescanning. Experimental results prove the robustness of this method against the aforementioned attacks.
Enzymology of tirapazamine metabolism: a review. (1998)

The enzymology of triapazamine (TPZ, SR 4233, WIN 59075, 3-amino-1,2,4-benzotriazene 1,4-dioxide, Tirazone) has been extensively studied in rodents and to a lesser extent in human systems. While it is clear that the initial reductive step in TPZ activation is enzyme-mediated, there is limited consensus in the published literature as to the relative contributions of the cellular reductases involved. Moreover, not only is the importance of subcellular localization for these putative activating reductase(s) far from clear, but their activity profiles in vivo are poorly defined. The same might also be said of the potential detoxifying enzymes. This review will attempt to establish what common ground exists regarding the enzymology of TPZ metabolism, and will relate the available evidence to the enzyme profiles found in human cell lines in vitro, as well as in xenograft models and human solid tumours.
Extraction and Quantitative HPLC Analysis of Coumarin in Hydroalcoholic Extracts of Mikania glomerata Spreng: ("guaco") Leaves (2001)

Methods for preparation of hydroalcoholic extracts of "guaco" (Mikania glomerata Spreng.) leaves were compared: maceration, maceration under sonication, infusion and supercritical fluid extraction. Evaluation of these methods showed that maceration under sonication had the best results, when considering the ratio extraction yield/extraction time. A high performance liquid chromatography (HPLC) procedure for the determination of coumarin in these hydroalcoholic extracts of "guaco" leaves is described. The HPLC method is shown to be sensitive and reproducible.
Probabilistic Relational Database Applications for Biomedical Informatics (2008)

In the information age, information is usually communicated and exchanged with heterogeneous databases in a distributed internetworking environment. When multiple heterogeneous databases show different values for the same data item, its actual value is not known with certainty. Probabilistic relational databases have extended from the relational database model by incorporating probability measures to capture the data uncertainty associated with data items. In this paper, we apply the probabilistic relational database techniques to the area of biomedical informatics. We address the issue of database interoperability by using a data warehousing approach to resolve mismatched domains and to integrate information from different data sources. We then develop query processing strategies to effectively evaluate and answer queries from the consolidated database.
Application of experimental design techniques to optimize a competitive ELISA (1996)

This paper describes the application of experimental design techniques to optimize a sensitive ELISA for a hapten molecule with a calibration range of 0-1000 pg/ml. Ten factors that were expected to affect the assay performance were initially screened, followed by factorial experiments to delineate the effects of the critical factors identified at the screening stage. Assay performance was evaluated using a unique rating system based on standard curve reproducibility, assay detection limits and the use of desirability functions. This rating system allowed multiple responses to be evaluated simultaneously. It was found that the substrate incubation time and enzyme label lot played an important role, while dilutions of the enzyme label and the anti-hapten antibody showed significant interaction. These observations were in good agreement with optimal assay conditions based on historical data collected over a period of two to three years. Application of experimental design techniques enabled us to confirm the significance of the factors affecting the assay within a three month period, with a minimum number of experiments. In addition, information on interaction between factors were determined.

Determination of the Diffusing Species and Diffusion Mechanism during CoSi , NiSi , and PtSi Formation by Using Radioactive Silicon as a Tracer (1989)

Information about the diffusing species and the mechanisms of diffusion during second‐phase formation of ,, and was obtained by using radioactive 31Si as a tracer. The position of the radioactive silicon tracer was determined after silicide formation by using sputter depth profiling and radioactivity measurement, the amount of silicide removed during sputtering being determined by Rutherford backscattering spectrometry of alpha particles. The metal was found to diffuse during growth, while Si appeared to be the dominant diffusing species for and formation. Radioactive silicon used as a tracer can also give information regarding the diffusion mechanisms occurring during silicide formation if silicon is the diffusing species. It was concluded that transformation of predominantly takes place by silicon grain boundary diffusion, whereas formation from apparently occurs by a combination of silicon grain boundary and silicon vacancy diffusion.
Experimental researches in electricity (1851)

Abstract The following is the order in which the several divisions of the subject treated of in this section of the author’s researches in electricity succeed one another:—1. Apparatus required. 2. Action of magnets on heavy glass. 3. Action of magnets on other substances acting magnetically on light. 4. Action of magnets on the metals generally. 5. Action of magnets on the magnetic metals and their compounds. 6. Action of magnets on air and gases. 7. General considerations. In giving an account of the contents of this paper, any attempt to follow the track of the author in the precise order in which he relates the consecutive steps of his progress in this new path of discovery, would fail of accomplishing its object; for, by adhering to such a course, it would scarcely be possible to comprise within the requisite limits of an abstract the substance of a memoir extending, as the present one does, to so great a length, and of which so large a portion is occupied with minute and circumstantial details of experiments; or to succeed in conveying any clear and distinct idea of the extraordinary law of nature brought to light by the author, and of the important conclusions which he has deduced.
Foveated Retinal Optimization for See-Through Near-Eye Multi-Layer Displays (2017)

In order to implement 3-D displays with focus cues, several technologies, including multi-layer displays, have been introduced and studied. In multi-layer displays, a volumetric 3-D scene is represented by 2-D layer images via optimization process. Although this methodology has been thoroughly explored and discussed in optical aspect, the optimization method has not been fully analyzed. In this paper, we deal with pupil movement that may prevent efficient synthesis of layer images. We propose a novel optimization method called foveated retinal optimization, which considers the foveated visual acuity of human. Exploiting the characteristic of human vision, our method has tolerance for pupil movement without gaze tracking while maintaining image definition and accurate focus cues. We demonstrate and verify our method in terms of contrast, visual metric, and experimental results. In experiment, we implement a see-through near-eye display that consists of two display modules, a light guide, and a holographic lens. The holographic lens enables us to design a more compact prototype as performing the roles of an image combiner and floating lens, simultaneously. Our system achieves <inline-formula xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink"> <tex-math notation="LaTeX">$38^\circ \times 19^\circ $ </tex-math></inline-formula> field of view, continuous focus cues, low aberration, small form factor, and clear see-through property.
Low voltage current-mode digitally controlled VGA based on digitally programmble current conveyors (2008)

A novel current-mode CMOS digitally controlled variable gain amplifier (VGA) is presented in this paper. The proposed VGA is based on new plusmn0.75 V digitally programmable second-generation current conveyors (DPCCII) with digital current gain control. The input stage of the DPCCII is realized using two complementary MOS differential pairs connected in parallel to ensure rail-to-rail operation. The output stage consists of a class-AB push-pull circuit, which guarantees high current driving capability. The digital control of the DPCCII, based on transistor arrays and MOS switches, provides variable current gain using an n-bits code-word. All proposed circuits are simulated using PSPICE with CMOS TSMC 0.25 mum technology.
Fabrication of large dimension aluminum air-bridges for superconducting quantum circuits (2013)

Proper grounding between different ground planes in coplanar superconducting qubit circuits is important to avoid spurious resonances which increase decoherence. Here, the authors present a possible solution to suppress such undesired modes using superconducting aluminum air-bridges which have been fabricated on top of aluminum coplanar waveguide transmission lines. 3D electromagnetic simulations were done to guide the design of the air-bridges such that the input reflection (S11) of the bridges was kept at a minimum level. A fabrication method based on optical lithography techniques was developed and it resulted in air-bridges with a height of approximately 10 μm and lengths of up to 500 μm. The method can be generalized to arbitrary length air-bridge with heights even exceeding 15 μm.
The importance of ammonia in proteinaceous attractants for fruit flies (Family: Tephritidae) (1981)

The responses of the Queensland fruit fly to food-based lures were studied, with particular emphasis on the importance of ammonia as an attractant or repellent. Certain solutions of ammonium bicarbonate were found to be highly effective attractants for the Queensland fruit fly, provided they were tested in traps in which the retention of the flies did not depend on their contacting the bait solution. The attractancies of such solutions were found to be strongly dependent on concentration and pH, and mean attractancies more than five times that of the commercial protein hydrolysate used as a standard were obtained. Highest attractancies were associated with ammonia evolution rates in the region 5-25 ¦l ammonia (s.t.p.) h-1 100 ml-1 of solution; rates above 400 ¦1 ammonia (s.t.p.) h-1 100 ml-1 appeared to be repellent. The addition of a mixture of amino acids to the ammonium bicarbonate solutions under these trap conditions had no significant effect on their attractancy; but the addition of the standard protein hydrolysate to a 0.001 M solution of ammonium bicarbonate, with pH adjusted to 8.5, produced an outstandingly effective lure, with a mean attractancy almost nine times as great as the standard hydrolysate alone at its normal pH of 4.8. Subsequent experiments showed that simply raising the pH of the standard protein hydrolysate to 8.5 caused a similar high attractancy, which could be due in part to the marked rise in ammonia production from endogenous sources. Protein hydrolysate solutions showed pronounced increases in both ammonia production and fruit fly attractancy when microorganisms were allowed to flourish. No such increases occurred when the microorganisms were inhibited with a preservative. Evidence is also presented which indicates that carbon dioxide is mildly repellent to the Queensland fruit fly.
Wake Measurements of a Multi-MW Wind Turbine with Coherent Long-Range Pulsed Doppler Wind Lidar (2010)

Abstract Long-range Doppler wind light detection and ranging (lidar) measurements at a wind turbine were carried out for the first time. The turbine was of the type Areva M5000 and is located at a site near the coastline in Bremerhaven, in the northern part of Germany. This wind turbine is the prototype for the German offshore test site “alpha ventus” and has a rated power of 5 MW. Information about the ambient wind field before and after this multimegawatt wind turbine was obtained. In this paper the measurement technique is discussed and the results of measurements in the diurnal layer and in the stable nocturnal boundary layer are shown. The main focus of this work is to determine the reduction of the wind speed at certain distances downstream from the rotor.

The performance of the star-pattern identification algorithm is verified through the use of software simulation.
Network Coding Method Using Heuristic Algorithms for Wireless Ad Hoc Networks (2010)

This paper first proves that the optimizing problems concerning network coding are NP-complete,and then puts forward a network coding method called COMP,using heuristic algorithms.This network coding method adopts the basic ideas of the set packing heuristic algorithm and the set cover heuristic algorithm with the aim of digging up as many network coding opportunities as many as possible.The results of the simulation carried out by the NS-2 simulator show that in scenarios where there are a large number of nodes,a small maximum transmission range,and a large number of sessions,this network coding method effectively alleviates the impact of session concurrency,improves the performance of the existing broadcast algorithm,and its performance improvement is greater than that of the existing network coding method.
The idea of proof (1985)

Any mathematical proof depends on valid arguments, and so a discussion of proof must consider logical relations between statements.
