Incremental regression testing (2002)

The purpose of regression testing is to ensure that bug fixes and new functionality introduced in a new version of a software do not adversely affect the correct functionality inherited from the previous version. Efficient methods of selecting small subsets of regression test sets that can be used to ensure correct functionality are explored.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">></ETX>
Effects of sex and growth on plasma concentrations of growth hormone, insulin‐like growth factor‐I and insulin in fattening simmental cattle (1992)

Zusammenfassung Einfluß von Geschlecht und Gewicht auf die Plasmakonzentrationen von Wachstumshormon (GH), Insulin‐like growth factor I (IGF‐I) und Insulin bei Mastrindern der Rasse Deutsches Fleckvieh Bei wachsenden Bullen, Ochsen und Färsen (Deutsches Fleckvieh) wurden die Blutplasma‐Konzentrationen von Wachstumshormon (GH), Insulin‐like‐growth‐factor I (IGF‐I) und Insulin bestimmt. Der Versuch bestand aus drei Versuchsdurchgängen und begann bei einem durchschnittlichen Alter von 3 Monaten beziehungsweise einem Lebendgewicht von 110 kg. Das Mastendgewicht betrug 510 kg (Färsen) und 660 kg (Bullen, Ochsen). Während der Mast wurden in jedem Versuchsdurchgang jeweils drei Tiere bei Mastgewichten von 200 kg, 360 kg und 425 kg (Färsen) bzw. 200 kg, 360 kg, 510 kg und 585 kg (Bullen, Ochsen) geschlachtet. Die Blutproben wurden durch Punktion in 14‐tägigem Abstand gewonnen. Die GH‐, IGF‐I‐ und Insulin‐Konzentrationen waren durch das Geschlecht signifikant beeinflußt (p<0.05). Die höchsten GH‐und IGF‐I‐Konzentrationen waren bei den Bullen gefolgt von den Ochsen und Färsen festzustellen. Die GH‐Konzentrationen zeigten einen gewichtsabhängigen Abfall bei Ochsen und Färsen, während die GH‐Konzentrationen bei Bullen wahrscheinlich aufgrund von Streß nur tendenziell mit zunehmendem Gewicht abfielen. Mit zunehmendem Gewicht stiegen die IGF‐I‐und Insulin‐Konzentrationen an. Die Veränderungen des Blutplasmaspiegels der Hormone werden hinsichtlich der Geschlechts‐ und Wachstumseinflüsse diskutiert. Aufgrund der physiologischen Effekte der Hormone und ihrer Blutplasmakonzentrationen im Hinblick auf die Schlachtkörperzusammensetzung wird gefolgert, daß IGF‐I beziehungsweise die Somatotropin‐Achse in Beziehung zum Proteinansatz und dem Muskelfleischanteil am Schlachtkörper steht, während der Fettansatz und die Schlachtkörperverfettung eher durch die Insulin‐Konzentration wiedergegeben wird.
Prediction of the eigenvectors for spatial multiplexing MIMO systems in time-varying channels (2006)

In mobile communications, time varying channels make the available channel information out of date. Timely updating the channel state is an obvious solution to improve the system performance in a time varying channel. However, a better knowledge of the channel comes at the cost of a decrease in the system throughput. Thus, predicting the future channel conditions can improve not only the performance but also the throughput of many types of wireless systems. This is especially true for a wireless system where multiple antennas are applied at both link ends. In this paper we propose and evaluate the performance of a prediction scheme for multiple input multiple output (MIMO) systems that apply spatial multiplexing. We aim at predicting the future precoder/decoder directly without going through the prediction of the channel matrix. The results show that in a slowly time varying channel an increase in the system performance by a factor of two is possible.
Introduction (2006)

This book considers the ways in which memory was represented in novels during the 1940s. Memory could feature as a structural device, with, for example, the loss of a protagonist's memory causing narrative complications. Its workings were also, on occasion, discussed and analysed within the narrative. In fact, these two aspects of memory — its structural and thematic functions — are not cleanly separable from each other, and their interaction can assist us in understanding how memory was conceptualized during this period. In this introduction, I will describe some of the ideas about memory, and about the condition of the novel, which were current in the interwar years. I will also consider debates about what the role of the novel ought to be that appeared once the conflict had begun. Such debates, which mainly took place in the pages of literary journals, are important and interesting, but I will not be confining my discussion to the 'highbrow' or 'literary' end of the fiction spectrum. Critics including Nicola Humble have recently acknowledged that the divisions we now perceive between literary fiction, usually of a modernist kind, and popular fiction, usually closer to realism, were not as absolute in the interwar years as they might now appear. During the 1920s, for example, 'middlebrow novelists were quick to adopt many of the themes and stylistic developments of the avant-garde, making meaningful distinctions very hard to draw' (Humble 19).KeywordsInvoluntary MemoryOedipus ComplexLiterary FictionNarrative TechniquePopular FictionThese keywords were added by machine and not by the authors.

Elevated Serum Calcitriol Concentrations Do Not Fall in Response to Hyperphosphatemia in Familial Tumoral Calcinosis (1985)

Five affected members in two branches of a Druze Arab kindred presented with calcified deposits in or about the hips and knees, indicating the diagnosis of tumoral calcinosis. Serum vitamin D metabolite concentrations, immunoreactive parathyroid hormone, and the tubular reabsorption of phosphate were measured in three affected siblings, as well as in their parents and an unaffected sibling. Normocalcemia and hyperphosphatemia with an elevated tubular maximum for phosphate per glomerular filtration rate were found in the affected patients. Levels of serum immunoreactive parathyroid hormone were normal, and the calcitriol value (1,25-dihydroxyvitamin D) was normal or elevated in the three affected patients. A trial of a low-phosphorus diet and oral aluminum hydroxide gel did not lower serum phosphate levels or improve the calcified deposits. These findings suggest that serum calcitriol values do not decline in response to hyperphosphatemia in tumoral calcinosis and that hyperphosphatemia with elevated tubular reabsorption of phosphate is a constant feature of this disorder because the kidney fails to excrete the increased filtered load of phosphate.
A 5th order 14 mWatt active polyphase filter for Analog and Digital TV on Mobile applications (2006)

To be compatible with a low-IF and zero-IF output interfaces and analog and digital TV standards a reconfigurable active polyphase filter has been developed for a DVB-T/H/analog TV receiver (TV-tuner) for mobile (portable) applications. The filter with a bandwidth of 8 MHz acts as a band pass filter with a centre frequency of 5 MHz or as a low pass filter with a cut-off frequency of 4 MHz. The balanced integrator filter (active RC) is based on a 5th order elliptic (Cauer) filter and achieves a stop-band suppression of more than 60 dB and a image rejection of 50 dB.

Influence of amino acids of a carrier protein flanking an inserted T cell determinant on T cell stimulation (1994)

CD4+ helper T cells recognize antigen in association with MHC class II molecules. To investigate the role of the context of a minimal T cell epitope on presentation and recognition in association with MHC class II molecules, an epitope of the 65 kDa heat shock protein of Mycobacterium tuberculosis was inserted at four different sites in the outer membrane protein PhoE of Escherichia coli. Only some of the constructs could stimulate the epitope-specific T cell clone A2b in vitro. One non-stimulatory construct could be made stimulatory by denaturation, suggesting that the protein conformation prevents correct presentation of the epitope. Other non-stimulatory constructs did not become stimulatory with denaturation. One of these constructs could be made stimulatory by substitution of either one of the two amino acids directly preceding the minimal epitope in the recombinant protein. In synthetic peptides the presence of these upstream residues did not interfere with T cell recognition, suggesting that these residues influence processing of the recombinant protein. Flanking amino acids also influenced induction of a T cell response against the inserted epitope in vivo. These results demonstrate that insertion of minimal T cell epitopes in carrier proteins for the design of vaccines might fail because of the inhibiting effects of flanking residues.
Intergeneric protplast fusion between xylanase producing Bacillus subtilis LYT and Corynebacterium acetoacidphilum ATCC 21476 (1990)

Hybrids between a strain of Bacillus subtilis isolated in our laboratory and having the ability to degrade xylan and other complex polysaccharides and Corynebacterium acetoacidophilum, a lysine producer, were prepared by protoplast fusion. Based on distinctive parental biochemical characteristics the fusants were grouped into 9 categories, viz. BC1 through BC9. Three of the hybrids, BC5, BC7a and BC7b, were tested for their ability to produce xylanase and lysine. Both BC7a and BC7b produced xylanase but BC5 did not, however all of them produced lysine albeit to different degrees. These results demonstrate that intergeneric gene transfer takes place through protoplast fusion between these 2 important genera of bacteria and some of the fusants inherit the useful traits of both the parents.
Aberration propeerties of diffractive triplets (1996)

Grading and staging of hepatic fibrosis, and its relationship with noninvasive diagnostic parameters (2003)

There is close correlation between liver fibrosis and inflammatory activity. The grading and staging of liver fibrosis are related to serum markers, Doppler ultrasonography, CT and/or MR imaging. The combination of the above mentioned noninvasive parameters are quite sensitive and specific in the diagnosis of hepatic fibrosis.
Follicle-Stimulating Hormone Induction of Ovarian Insulin-Like Growth Factor-Binding Protein-3 Transcription Requires a TATA Box-Binding Protein and the Protein Kinase A and Phosphatidylinositol-3 Kinase Pathways (2005)

The current study was done to elucidate the mechanism of the FSH stimulation of IGF-binding protein 3 (IGFBP-3) expression and map the FSH response element on the pig IGFBP-3 promoter. Forskolin induced IGFBP-3 reporter activity in transiently transfected granulosa cells. The protein kinase A (PKA) inhibitor [N-[2-(p-bromocinnamyl)amino)ethyl]-5-isoquinolinesulfonamide, 2HCl] (and cotransfection with a PKA inhibitor expression vector), the phosphatidylinositol-3 kinase inhibitor [2-(4-morpholinyl)-8-phenyl-4H-1-benzopyran-4-one], and the ERK inhibitor [1,4-diamino-2,3-dicyano-1,4-bis(2-aminophenylthio)butadiene], all blocked FSH stimulation. Use of serial deletion constructs and site-directed mutagenesis show that a TATA box-binding protein site is required for FSH stimulation and that a specific protein 1 (Sp1) site is required for basal transcription. Gel shift assays of nuclear protein with a -61/-25 probe detected four protein-DNA complexes, with bands I and II having significantly higher intensities in FSH-treated cells than in controls. Mutation of the Sp1 site prevented formation of bands I and II whereas mutation of the TATA box-binding protein site prevented formation of band IV. Use of specific antibodies showed that Sp1 participates in formation of band I, Sp3 band II, and p300 in both I and II. Band III was nonspecifically competed out. We conclude that FSH stimulation of IGFBP-3 transcription is mediated by cAMP via the PKA pathway and requires the P1-3 kinase and likely the MAPK pathways.

Chiral Detection in High-Performance Liquid Chromatography by Vibrational Circular Dichroism (1994)

A novel chiral detector for high-performance liquid chromatography has been developed. This detector is based on the measurement of circular dichroism of chiral effluents in the infrared region, i.e., vibrational circular dichroism (VCD). In this instrument, a solid-state spectral tunable (from 2.4 to 3.5 microns) F-center laser was used as the light source. The linearly polarized laser beam was converted into left circularly polarized light (LCPL) and right circularly polarized light (RCPL) at 42 kHz by means of a photoelastic modulator. The intensity of the LCPL and RCPL transmitted through the sample was measured by a liquid nitrogen cooled indium antimonide detector. Double modulation was employed to reduce the noise associated with the laser beam. Specifically, the linearly polarized laser beam, prior to being converted to CPL, was modulated at 85 Hz by a mechanical chopper. Demodulation and amplification were accomplished with the use of two lock-in amplifiers. In its present configuration, the instrument can be used to measure the VCD of O-H groups. Its sensitivity is so high that it was able, for the first time, to detect chirally (with limits of detection of micrograms) (R)- and (S)-2,2,2-trifluoro-1-(9- anthryl)ethanol and (R)- and (S)-benzoin when these compounds were chromatographically separated from the corresponding racemic mixtures by a Chiralcel-OD column. The main advantage of this chiral detector is, however, its universality; i.e., it can be used to virtually detect any chiral compounds which has O-H group (e.g, aliphatic alcohols such as 2-octanol).
Self-assembled dithiocarbamate–copper(ii) macrocycles for electrochemical anion recognition (2001)

A novel family of redox-active dinuclear copper(II)-based macrocycles self-assembled from dithiocarbamate ligands has been synthesised; a naphthyl-spaced complex exhibits selective electrochemical recognition of perrhenate and dihydrogenphosphate anions.
Classifying muscle states with ultrasonic single element transducer data using machine learning strategies (2019)

Being able to distinguish non-invasively between different muscle states is crucial for rehabilitation and sports athletes alike. The analysis of muscle activities is often performed using optical systems, kinetic approaches or surface electromyography. However, these methods can only obtain information from the body surface. In this work, raw ultrasound radio frequency data is used for muscle state classifications as this method provides information from deeper muscle layers. A setup to classify muscle contractions with artificial neural networks and traditional time series analysis algorithms is presented. Experiments with the pulser-receiver Olympus 5800PR and Panametrics transducers were performed to obtain A-scans from the calves of healthy volunteers. Dimensionality reduction techniques, such as (Kernel-) Principal Component Analysis and t-Distributed Stochastic Neighbor Embedding were applied, which provide information about the distribution of A-scans belonging to relaxed and contracted muscle states. A comparison of different ML methods is presented with average F1 scores of up to 89 % after appropriate post-processing for muscle contraction classifications and average F1 scores of up to 76 % for muscle fatigue state classifications. We conclude that low-cost ultrasound measurements can be used for reliable muscle activity tracking. More data is expected to result in even more robust future solutions.
Metabolic Flux Responses to Pyruvate Kinase Knockout in <i>Escherichia coli</i> (2002)

The intracellular carbon flux distribution in wild-type and pyruvate kinase-deficient Escherichia coli was estimated using biosynthetically directed fractional 13C labeling experiments with [U-13C6]glucose in glucose- or ammonia-limited chemostats, two-dimensional nuclear magnetic resonance (NMR) spectroscopy of cellular amino acids, and a comprehensive isotopomer model. The general response to disruption of both pyruvate kinase isoenzymes in E. coli was a local flux rerouting via the combined reactions of phosphoenolpyruvate (PEP) carboxylase and malic enzyme. Responses in the pentose phosphate pathway and the tricarboxylic acid cycle were strongly dependent on the environmental conditions. In addition, high futile cycling activity via the gluconeogenic PEP carboxykinase was identified at a low dilution rate in glucose-limited chemostat culture of pyruvate kinase-deficient E. coli, with a turnover that is comparable to the specific glucose uptake rate. Furthermore, flux analysis in mutant cultures indicates that glucose uptake in E. coli is not catalyzed exclusively by the phosphotransferase system in glucose-limited cultures at a low dilution rate. Reliability of the flux estimates thus obtained was verified by statistical error analysis and by comparison to intracellular carbon flux ratios that were independently calculated from the same NMR data by metabolic flux ratio analysis.
Improvement of Emulsifying and Antibacterial Properties of Salmine by the Maillard Reaction with Dextran (1999)

In order to improve the emulsifying and antibacterial properties of salmine (a protamine from salmon sperm), its conjugates with dextran (molecular weight 60, 000-90, 000) were prepared through the Maillard reaction above glass transition temperature (Tg). Development of brown color and formation of salmine-dextran conjugates were concomitantly accelerated at heating temperatures above Tg+30°C. The emulsifying activity of the conjugates became 4-5 times as high as that of salmine during the early stage of the Maillard reaction at 180-190°C, but decreased drastically at the advanced stage. The antibacterial activity of salmine was also increased by the conjugation with dextran. Even antibacterial activity against some species of Gram-negative bacteria was attained as a result of the conjugation. Potential use of salmine-dextran conjugates as bifunctional food additives is discussed.

Synthesis, Characterization, and Application of Two Al(OR<sup>F</sup>)<sub>3</sub> Lewis Superacids (2012)

We report herein the synthesis and full characterization of the donor-free Lewis superacids Al(OR(F))(3) with OR(F) = OC(CF(3))(3) (1) and OC(C(5)F(10))C(6)F(5) (2), the stabilization of 1 as adducts with the very weak Lewis bases PhF, 1,2-F(2)C(6)H(4), and SO(2), as well as the internal C-F activation pathway of 1 leading to Al(2)(F)(OR(F))(5) (4) and trimeric [FAl(OR(F))(2)](3) (5, OR(F) = OC(CF(3))(3)). Insights have been gained from NMR studies, single-crystal structure determinations, and DFT calculations. The usefulness of these Lewis acids for halide abstractions has been demonstrated by reactions with trityl chloride (NMR; crystal structures). The trityl salts allow the introduction of new, heteroleptic weakly coordinating [Cl-Al(OR(F))(3)](-) anions, for example, by hydride or alkyl abstraction reactions.
Wireless power transfer technology using magnetic field resonance (2013)

This paper describes the basic principles of wireless power transfer technology based on magnetic field resonance. In addition, we introduce applications including the LED TV, OLEV, and HH-RM CCC Charger. In order to demonstrate the advantages of the coil structure with the ferrimagnetic material and metallic shielding, magnetic field distributions and the electrical performance of three different coil structures were investigated via 3D electromagnetic (EM) field solver and SPICE simulation. In addition, EMF and electromagnetic field radiation were measured and analyzed.
Androgen regulation of micro‐RNAs in prostate cancer (2010)

Only a few miRNAs were found to be androgen-regulated in both cell lines and xenografts models. Of those, the expression of miR-141 was upregulated in cancer. The ectopic overexpression of miR-141 increased growth of LNCaP cell suggesting it may contribute to the progression of PC.
Selective Tribocharging of Particles for Separation (1993)

Selective tribocharging is a suitable way for separating mineral constituents from heterogeneous mixtures using an electrostatic field. Though contact charging mechanisms have been studied intensively, understanding is far from clear and complete, due to the variability of material properties and to the influence of ambient conditions, which are often difficult to control. After outlining the scientific fundamentals of contact electrification, the paper illustrates and discusses some significant cases of selective charging of minerals under different experimental conditions, pointing out the effect of operational variables. Separators of practical interest are briefly described, the performance of which is assessed on the basis of beneficiation results obtained for a variety of ores and coal both on a laboratory and industrial scale.

High Gain Soft-Switching Bidirectional DC–DC Converter for Eco-Friendly Vehicles (2013)

This paper proposes a nonisolated soft-switching bidirectional dc-dc converter suitable for high step-up and step-down applications. The proposed converter can achieve zero voltage switching turn on of all switches and zero-current-switching turn off of some switches in continuous conduction mode in both forward and reverse modes. An optimized switching strategy is presented to minimize switch current rating and achieve soft switching in wider range. An intermediate switching pattern is introduced to carry out seamless mode change. Experimental results from a 5-kW prototype are provided to validate the proposed concept.
