Study on metabolism of N-Butyl Benzyl Phthalate (BBP) and Dibutyl Phthalate (DBP) in Ctenopharyngodon idellus by GC and LC-MS/MS (2012)

To deeply study the toxic effect and mechanism of Dibutyl Phthalate (DBP) and Butyl Benzyl Phthalate (BBP) in fish, their in vivo and in vitro metabolism was investigated in this study. At first, a gas chromatography method was developed for simultaneous determination of DBP and BBP in blood serum, hepato-pancreas homogenate, intestine homogenate and hepatocyte medium. Then the main metabolites of the two PAEs chemicals were identified in Ctenopharyngodon idellus tissues by HPLC-MS/MS. And the results showed that DBP and BBP were metabolized quickly in blood serum, intestinal tract and hepato-pancreas homogenate, especially in the serum and the main metabolites were monobutyl phthalate (mBP) and monobenzyl phthalate (mBzP). However, they were not metabolized significantly in hepatocyte medium and the main metabolites in urine were the corresponding mono-phthalates and their conjugates of glucuronic acid. These studies indicated that DBP and BBP were hydrolyzed into mono-esters in some tissues in varying degrees, which were metabolized into corresponding conjugates combined with glucuronic acid later, and that will contribute to the elimination of PAEs from C. idellus. The blood and intestine were the first metabolized location of PAEs chemicals absorbed through fish’s gill and intestine.

Analogue simulation of the nonlinear transfer characteristics: a novel approach (1978)

A practical technique for the analogue simulation of the arbitrary nonlinear monotonic and nonmonotonic transfer characteristic is presented in this paper. Using operational amplifier and function generator with the monotonic transfer characteristic, any nonmonotonic function with the arbitrary slope is generated.
Identification of the lesion in the stimulatory GTP‐binding protein of the uncoupled S49 lymphoma (1987)

The stimulatory GTP-binding protein (Gs) of the uncoupled mutant of S49 lymphoma cells is deficient in its ability to transduce hormonal signals from ligand-bound beta-adrenergic receptors to the catalytic component of adenylate cyclase. In order to define the genetic defect in the Gs of uncoupled S49 cells, a complementary DNA clone encoding the alpha-subunit of Gs was analyzed and the deduced primary structure of the defective subunit compared to that of the wild-type subunit. A single nucleotide transversion was found that coded for a proline rather than an arginine at residue 389. The results indicate a domain of the alpha-subunit of Gs that specifically interacts with hormone receptors.
Biologically Inspired Networking (2006)

Biological systems are typically better at adapting to new situations than computers because their design emphasizes robustness and sustainability even though the proximal response may not be the optimal one. In an information network such as the Internet, data are broken up into packets before being transmitted, and each packet can take a different path across the nodes of the network. How might a method for data transmission over multiple paths be redesigned whereby the network can itself adapt to an unpredictable and fluctuating environment?
Fuzzy Edge Detection in Biometric Systems (2007)

This paper proposes a fuzzy logic based edge detector for feature extraction in biometric systems such as face and palm print recognition. Edge detection is carried out by means of global (histogram of gray levels) and local (pixels within in a window) information. The local information is fuzzified by employing a modified Gaussian membership function. Using the contrast intensification operator, the image is enhanced to the required level of visual quality by entropy optimization of fuzzification parameters. Furthermore, the local edge detection operator is applied on the enhanced image using parameters obtained from entropy optimization. Finally, a simple threshold is applied to produce the skeleton image. Results demonstrate that this edge detector is well suited for feature extraction in biometric image systems.

Enhancing security of stored biometric data (2014)

A biometric system is weak to a different type of attacks targeted at undermining the reliability of the verification process. These attacks are either imposter or irrevocability. Imposter means information stored in database, can be abused to construction of artificial biometric and replace it for fake authentication and irrevocability means once compromised, biometric not be updated, reissued or destroyed. In this paper we present a general architecture with the help of Digital Signature that guarantees privacy protection of biometric data. We specifically focus on secure a biometric data at the time of authentication and storage.
The high voltage/high power FET (HiVP) (2003)

A new device configuration is presented: the High-Voltage/High-Power device (HiVP). This original configuration can dramatically improve the power and decrease the complexity of designing power amplifiers, leading to low cost and higher power. The HiVP uses a new concept, never achieved before, to simultaneously bias a semiconductor device at high voltage while maintaining an optimum output matching impedance close to 50 Ohms. The concept could be applied to many device technologies such as the GaAs MESFET, HEMT, and the Si MOSFET, to combine the power of several devices to achieve higher power output over broader bandwidth.
Child of the Long Take: Alfonso Cuaron's Film Aesthetics in the Shadow of Globalization (2009)

Abstract Alfonso Cuaron's 2006 film, Children of Men, not only suggests that the economic pressures on contemporary Hollywood directors differ little from those in the studio era, it also suggests that film style in the age of globalization is not as homogenized as many fear. The long take is the most prominent feature in Children of Men, including many which are digitally contrived. Lofty reasons by the filmmakers are given for these long takes, but there are more pedestrian reasons behind this. Other examples past and present suggest that often the long take serves the needs of both filmmakers and their producers, at least for awhile. Cuaron himself paid his dues over the years with more generic films, and is now making a bold auteurist declaration with these long takes. The question remains whether the economics of Hollywood will allow him to continue.
Mapping clinically useful terminology to a controlled medical vocabulary. (1994)

We have mapped clinically used diagnostic terms from a legacy ambulatory care system to the separate controlled vocabulary of our central clinical information system. The methodology combines elements of lexical and morphologic text matching techniques, followed by manual physician review. Results of the automated matching algorithm before and after partial manual review are presented. The results of this effort will permit the migration of coded clinical data from one system to another. Output from the system after the term review process will be fed back to the target vocabulary via automated and semi-automated means to improve its clinical utility.
Development of triple insulated wire (2002)

We completed a three insulation-layered winding wire for a switching transformer, which is fabricated by extrusion and equipped with a withstand voltage even greater than those of conventional enameled wires. Also, its insulation layer is of half the thickness which conventional extrusion techniques build up. This wire product can meet the requirements for "reinforced insulation" under current safety standards, and does not require interlayer insulation tape or a barrier which are indispensible in conventional transformers. As a consequence, switching transformers can be drastically miniaturised and improved in efficiency. Meanwhile, its insulation layer, without being stripped, accepts soldering which produces almost the same work efficiency as soldering workability of enameled wires used for similar transformers. This paper deals with soldering workability and best fit soldering equipment.
[SEM study of morphologyc and incidence of accessory canals in the furcation region of permanent molars]. (2001)

In the light of these findings, the authors advise disinfecting and filling the dental pulp cavity during root treatment and, in the event of severe periodontal disease, evaluating the vitality of dental elements before surgery, thus ensuring a correct therapeutic approach by not overlooking the possibility of combined lesions.
Study of contactless inductive charging platform with core array structure for portable products (2011)

In this research, contactless power transmission technique is applied in the charging of lithium battery for portable electronic products and the concept of common charging platform is proposed. The charging platform is comprised of several pot type cores with array structure, allowing circuit to be charged within a permitted region of displacement on the charging platform. However, a larger air gap exists in contactless structure compared to other contact structures, i.e. poor power transmission efficiency. In order to overcome the weakness, phase-locked loop (PLL) is applied to enable the operation frequency of circuit to be maintained above primary resonant frequency and microprocessor is utilized to improve the transmission efficiency when charging platform is standby. In addition, printed-circuit-board (PCB) is utilized on the secondary to reduce the thickness of the secondary circuit, forming PCB coil. Experimental results show that the transmission efficiency between contactless inductive structures is 55% under the condition of charging current 200 mA and air gap 2.5 mm.
FolkRank: A Ranking Algorithm for Folksonomies (2006)

In social bookmark tools users are setting up lightweight conceptual structures called folksonomies. Currently, the information retrieval support is limited. We present a formal model and a new search algorithm for folksonomies, called FolkRank, that exploits the structure of the folksonomy. The proposed algorithm is also applied to find communities within the folksonomy and is used to structure search results. All findings are demonstrated on a large scale dataset. A long version of this paper has been published at the European Semantic Web Conference 2006 [3].
The pseudoexhaustive test of sequential circuits (1992)

The concept of a pseudoexhaustive test for sequential circuits is introduced in a way similar to that which is used for combinational networks. Using partial scan all cycles in the data flow of a sequential circuit are removed, such that a compact combinational model can be constructed. Pseudoexhaustive test sequences for the original circuit are constructed from a pseudoexhaustive test set for this model. To make this concept feasible for arbitrary circuits a technique for circuit segmentation is presented which provides special segmentation cells as well as the corresponding algorithms for the automatic placement of the cells. Example circuits show that the test strategy requires less additional silicon area than a complete scan path. Thus the advantages of a partial scan path are combined with the well-known benefits of a pseudoexhaustive test, such as high fault coverage and simplified test generation.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">></ETX>
Protein-Protein Interactions in Assembly of Lipoic Acid on the 2-Oxoacid Dehydrogenases of Aerobic Metabolism (2011)

Lipoic acid is a covalently attached cofactor essential for the activity of 2-oxoacid dehydrogenases and the glycine cleavage system. In the absence of lipoic acid modification, the dehydrogenases are inactive, and aerobic metabolism is blocked. In Escherichia coli, two pathways for the attachment of lipoic acid exist, a de novo biosynthetic pathway dependent on the activities of the LipB and LipA proteins and a lipoic acid scavenging pathway catalyzed by the LplA protein. LipB is responsible for octanoylation of the E2 components of 2-oxoacid dehydrogenases to provide the substrates of LipA, an S-adenosyl-L-methionine radical enzyme that inserts two sulfur atoms into the octanoyl moiety to give the active lipoylated dehydrogenase complexes. We report that the intact pyruvate and 2-oxoglutarate dehydrogenase complexes specifically copurify with both LipB and LipA. Proteomic, genetic, and dehydrogenase activity data indicate that all of the 2-oxoacid dehydrogenase components are present. In contrast, LplA, the lipoate protein ligase enzyme of lipoate salvage, shows no interaction with the 2-oxoacid dehydrogenases. The interaction is specific to the dehydrogenases in that the third lipoic acid-requiring enzyme of Escherichia coli, the glycine cleavage system H protein, does not copurify with either LipA or LipB. Studies of LipB interaction with engineered variants of the E2 subunit of 2-oxoglutarate dehydrogenase indicate that binding sites for LipB reside both in the lipoyl domain and catalytic core sequences. We also report that LipB forms a very tight, albeit noncovalent, complex with acyl carrier protein. These results indicate that lipoic acid is not only assembled on the dehydrogenase lipoyl domains but that the enzymes that catalyze the assembly are also present "on site."
Agile Business Objects Management Application for Electronic Records Archive Transfer Process (2009)

In order to continue to fulfill its mission in the information technology age, the National Archives and Records Administration (NARA) has made the decision to develop the Electronic Records Archives (ERA) system. One of the goals is to provide to the archivists a modernized system with automatic workflow that can streamline the digital archive business process. For an archival system, Ingest is one of the core components. As part of the ingest process, this component would allow the record Producer to negotiate submission agreement before transferring digital materials into the system. Within the framework of a service-oriented architecture with business process management, the ERA system uses XML to represent business objects and metadata. In this paper, we will show how the synergetic combination of XForms and Genericode makes the system agile and responsive to business user requirements. Furthermore, the approach fits well with ERA's design principle to use international and industry standards, and facilitates the integration of XML business objects and the electronic records metadata. We believe that the standard-based approach of XForms+Genericode exposed in this paper can be generalized to develop any e-Forms system with a set of control values and vocabularies.
Digital filtering of EMG-signals. (1989)

Even under field conditions the registration of EMG-signals is often interfered with artifacts. For quantitative signal processing it is necessary to eliminate artifacts and noise from the EMG raw data. We show a simple and efficient way with the help of a recursive digital first order Butterworth filter. This filter-type has a great slope steepness and requires minimal calculations. The algorithm is derived and easily programmable.
Theoretical Study of C–H Bond Cleavage via Concerted Proton-Coupled Electron Transfer in Fluorenyl-Benzoates (2018)

Developing new strategies to activate and cleave C-H bonds is important for a broad range of applications. Recently a new approach for C-H bond activation using multi-site concerted proton-coupled electron transfer (PCET) involving intermolecular electron transfer to an oxidant coupled to intramolecular proton transfer was reported. For a series of oxidants reacting with 2-(9 H-fluoren-9-yl)benzoate, experimental studies revealed an atypical Brønsted α, defined as the slope of the logarithm of the PCET rate constant versus the logarithm of the equilibrium constant or the scaled driving force. Herein this reaction is modeled with a vibronically nonadiabatic PCET theory. Hydrogen tunneling, thermal sampling of the proton donor-acceptor mode, solute and solvent reorganization, and contributions from excited vibronic states are found to play important roles. The calculations qualitatively reproduce the experimental observation of a Brønsted α significantly less than 0.5 and explain this shallow slope in terms of exoergic processes between pairs of electron-proton vibronic states. These fundamental mechanistic insights may guide the design of more effective strategies for C-H bond activation and cleavage.
Effect of Macroconidial Suspension Volume and Concentration on Expression of Resistance to<i>Fusarium graminearum</i>in Maize. (1995)

The effects of volume and concentration of macroconidial suspensions applied to maize silks on resistance to Fusarium graminearum infection were investigated on three maize hybrids (Pride K127, Pioneer 3953, and Dekalb DK-415). Plants were inoculated in the field by injecting a spore suspension into the silk channel of individual ears. Disease severity and deoxynivalenol (DON) concentration in grain were determined at harvest. In three experiments, plants were inoculated with 1) six conidial suspension volumes ranging from 0,5 to 10 ml in 1991 and 1992; 2) seven spore concentrations ranging from 0 to 2 × 10 6 spores per milliliter in 1990, 1991, and 1992; and 3) three spore concentrations (2 × 10 5 , 5 × 10 5 , and 2 × 10 6 spores per milliliter) inoculated at six silk ages (1, 3, 5, 7, 12, and 18 days after silk emergence) in 1991 and 1992. On average, Pride K127 was most resistant, followed by Pioneer 3953 and Dekalb DK-415. Disease severity, and in most cases DON, increased with increased conidial suspension volume and concentration, with greater effects in susceptible hybrids. Disease severity decreased with silk age over all spore concentrations. When screening for resistance to infection via the silk, 2 ml of a 5 × 10 5 spores per milliliter suspension injected into the silk channel at approximately 6 days after silk emergence should give adequate differentiation of genotypes
ADVANCED RECEIVERS FOR HIGH DATA RATE MO- BILE COMMUNICATIONS (2006)

Improving the spectral efficiency is a key issue in the future wireless communication systems since the spectrum is a scarce resource. Both the number of users as well the demanded data rates are increasing all the time. Furthermore, in mobile communications the wireless link is required to be reliable even when the mobile is in a fast moving vehicle. Using Multiple-Input Multiple-Output (MIMO) antennas is a well known technique to provide higher spectral efficiency as well as better link reliability. Additionally, higher order modulation methods can be used to provide higher data rates. In order to benefit from these enhancements in practise, sophisticated signal processing methods as well as accurate estimates of time-varying wireless channel parameters are needed.\n\nThis thesis addresses the problem of designing multi-antenna receivers in high data rate systems. The case of multiple transmit antennas is also considered. System specific features of High Speed Downlink Packet Access (HSDPA) which is part of 3rd generation (3G) Wideband Code Division Multiple Access (WCDMA) evolution are exploited in channel estimation methods and in MIMO receiver design. Additionally, complexity reduction methods for Minimum Mean Square Error (MMSE) equalization are addressed.\n\nBlind channel estimation methods are spectrally efficient, since no extra resources are needed for pilot signals. However, in mobile communications accurate estimates are needed also in fast fading channels. Consequently, semi-blind channel estimation methods where the receiver combines blind and pilot based channel estimation are an appealing alternative. In this thesis blind and semi-blind channel estimation methods based on knowledge of multiple spreading codes are derived. A novel semi-blind combining scheme for code multiplexed pilot signal and blind estimation is proposed.\n\nAnother important factor in receiver design criteria is the structure of interference in the received signals. Interference mitigation techniques in MIMO systems have been shown to be potential methods for providing improved performance. A chip level inter-antenna interference cancellation method has been developed in this thesis for HSDPA. Furthermore, this multi-stage ordered interference canceler is combined with the semi-blind channel estimation scheme to enhance the system performance further.
Estimating Historical Functional Linear Models with a Nested Group Bridge Approach (2018)

We study a scalar-on-function historical linear regression model which assumes that the functional predictor does not influence the response when the time passes a certain cutoff point. We approach this problem from the perspective of locally sparse modeling, where a function is locally sparse if it is zero on a substantial portion of its defining domain. In the historical linear model, the slope function is exactly a locally sparse function that is zero beyond the cutoff time. A locally sparse estimate then gives rise to an estimate of the cutoff time. We propose a nested group bridge penalty that is able to specifically shrink the tail of a function. Combined with the B-spline basis expansion and penalized least squares, the nested group bridge approach can identify the cutoff time and produce a smooth estimate of the slope function simultaneously. The proposed locally sparse estimator is shown to be consistent, while its numerical performance is illustrated by simulation studies. The proposed method is demonstrated with an application of determining the effect of the past engine acceleration on the current particulate matter emission.
Effects of copper and zinc ions on the germicidal properties of two popular pharmaceutical antiseptic agents cetylpyridinium chloride and povidone-iodine† (1998)

The effects of copper and zinc ions on the rate of killing of Gram-negative bacterium Pseudomonas aeruginosa, Gram-positive bacterium Staphylococcus aureus and fungal yeast Candida albicans by antiseptic agents cetylpyridinium chloride and povidone-iodine (Betadine) were investigated. In the 48 test cases copper and zinc ions clearly potentiated the antiseptic agents in 28 (58.3%) cases and exhibited an improved (not clear potentiation) activity in 15 (31.3%) cases. In five (10.4%) cases there was no change in the antiseptics' antimicrobial activity. In general zinc potentiated the antiseptic agents more than copper. If an 'improved activity' was the only criterion for this study, then a more rapid antimicrobial effect was observed in 43 out of the 48 test cases, i.e., 90%.
