Characteristics of wavefront propagation in circuits causing human ventricular tachycardia (2002)

The conduction characteristics of human ventricular tachycardias (VT) have not been fully defined. The authors used a non-contact system to map 11 reentrant VT in 8 patients. Propagation velocities and 3-dimensional angles of turn were calculated from Cartesian co-ordinates. The complete diastolic pathway (DP) was mapped in 7 VT patients. DP wavefront velocity was 0.82/spl plusmn/0.49 m/s. Significant changes (>5 degrees/mm) in trajectory of propagation (TOP) occurred within 8 DP segments, in which propagation slowed to 0.41/spl plusmn/0.11 m/s compared with 0.91/spl plusmn/0.16 m/s preceding (p<0.05) and 1.07/spl plusmn/0.33 following (p<0.05) change in TOP. At entry turning points (TP) propagation velocity slowed from 1.3/spl plusmn/0.4 ms to 0.6/spl plusmn/0.26 ms (P<0.001), but did not change at exit TP on leaving the distal DP (0.72/spl plusmn/0.28 vs 0.8/spl plusmn/0.25 m/s, p=ns). In conclusion, slowing of propagation in human VT circuits occurs over regions of wavefront turning.
Migration record of Japanese sea bass Lateorabrax japonicus using ultrasonic biotelemetry (2003)

関西国際空港護岸域において採捕したスズキに超音波発信機を装着し,2001年8月に9個体,11月に11個体を放流した。護岸域に設置した受信機で行動を連続測定した結果,受信が記録され続ける個体と放流直後から記録されない個体が確認された。記録が続いた個体でも,1日以上記録の途切れる期間があり,受信範囲(約350m)を越える沖合へと移動したと考えられる。産卵期以前は小潮時に,産卵盛期は寒波・低気圧の到来時に多くの個体で記録が途切れた。スズキの沖合への移動はこれら生息環境の変化に対応していると推察された。
Proper Orthogonal Decomposition Analysis of a Turbulent Swirling Self-Excited Premixed Flame (2015)

Thermoacoustic oscillations constitute a serious threat to the integrity of combustion systems. The goal of the present work is to determine the effect of the equivalence ratio (φ), inlet flow velocity (U), and burner geometry on the characteristics of the self-excited oscillations and to reveal the dominant mechanisms. It also focuses on the data post-processing aiming at extracting information about the dynamics that are not captured through classical ensemble-averaging, and hence the Proper Orthogonal Decomposition technique is used. Experiments were conducted with a fully-premixed air/methane flame stabilized on a conical bluff body. Self-excited acoustic instabilities were induced by extending the length of the combustion chamber downstream of the bluff body. The flame was visualised using OH* chemiluminescence and OH PLIF at 5 kHz. Proper Orthogonal Decomposition (POD) and Fast Fourier Transform analysis were conducted on the imaging data. A strong effect of the chamber length was found, which primarily drove the generation of acoustic oscillation and flame-vortex interaction. Significant differences in the flame roll-up were found when either the burner geometry or the equivalence ratio was altered. Changes were detected in the frequency of oscillations, which showed a general trend to increase with φ and U and decrease with the length of the duct. Analysis of the POD modes allowed an estimate of the convection speed of the flame structures associated with the dominant frequency and it was found that this convection speed was about 1.5 U for most conditions studied.
Measurement of Spherical Aberration Utilizing an Alternating Phase Shift Mask (1998)

A spherical aberration function is measured utilizing an alternating phase shift mask (PSM). First, it is theoretically considered that with a highly coherent illumination, the focus of the alternating phase shift lines and spaces (L/S) pattern is equivalent to that of rays in a small annular area of the reference sphere when the aberration function is axially symmetric in the sphere. Then, the focus variation with the pattern pitch is obtained by a printing experiment that employs an alternating PSM. After a primitive mathematical operation, the aberration function is obtained from the experimentally observed focus variation. The aberration function is examined by investigating various anomalous phenomena observed in the printing with the various resolution enhancement techniques (RETs). The comparison between the experimentally observed phenomena and the predictions based on the calculated images with the measured aberration functions shows fair agreement. Consequently, the validity of this measurement method is confirmed.
Proposed experiment for the observation of surface plasmons in semiconductor superlattices (1987)

It is shown that for an increased charge density on the outermost layer, the semi-infinite semiconductor superlattice can sustain a surface plasmon even in the absence of a dielectric mismatch at the surface. An experiment is proposed to observe this as-yet-unobserved surface mode.
Symbiotic jobscheduling with priorities for a simultaneous multithreading processor (2002)

Simultaneous Multithreading machines benefit from jobscheduling software that monitors how well coscheduled jobs share CPU resources, and coschedules jobs that interact well to make more efficient use of those resources. As a result, informed coscheduling can yield significant performance gains over naive schedulers. However, prior work on coscheduling focused on equal-priority job mixes, which is an unrealistic assumption for modern operating systems.This paper demonstrates that a scheduler for an SMT machine can both satisfy process priorities and symbiotically schedule low and high priority threads to increase system throughput. Naive priority schedulers dedicate the machine to high priority jobs to meet priority goals, and as a result decrease opportunities for increased performance from multithreading and coscheduling. More informed schedulers, however, can dynamically monitor the progress and resource utilization of jobs on the machine, and dynamically adjust the degree of multithreading to improve performance while still meeting priority goals.Using detailed simulation of an SMT architecture, we introduce and evaluate a series of five software and hardware-assisted priority schedulers. Overall, our results indicate that coscheduling priority jobs can significantly increase system throughput by as much as 40%, and that (1) the benefit depends upon the relative priority of the coscheduled jobs, and (2) more sophisticated schedulers are more effective when the differences in priorities are greatest. We show that our priority schedulers can decrease average turnaround times for a random jobmix by as much as 33%.
Real-time threshold-voltage control scheme for low-power VLSI under fluctuation of a supply voltage (2006)

In the recent sub-90nm VLSI generation, a fluctuation exists in a supply voltage due to IR-drop and inductance effects. A supply voltage fluctuation in VLSI chips causes large variations in the logic delay time and power consumption. However, in conventional low-power VLSI architecture such as variable threshold voltage CMOS (VTCMOS), the threshold voltage of a transistor is fixed in advance at the system design level. As a result, VTCMOS can't compensate a supply voltage fluctuation. By employing an adaptive threshold voltage control (ATVC), minimization of power consumption under a time constraint is achieved even in the presence of a supply voltage fluctuation. Optimal granularity is discussed to minimize the total power consumption.

MIC and time-kill study of antipneumococcal activities of RPR 106972 (a new oral streptogramin), RP 59500 (quinupristin-dalfopristin), pyostacine (RP 7293), penicillin G, cefotaxime, erythromycin, and clarithromycin against 10 penicillin-susceptible and -resistant pneumococci (1996)

Broth MICs and time-kill studies were used to test the activity of RP 59500 (quinupristin-dalfopristin), RPR 106972, pyostacine (RP 7293), erythromycin, clarithromycin, and cefotaxime for four penicillin-susceptible (MICs of 0.008 to 0.03 microgram/ml), two penicillin-intermediate (MIC of 0.25 microgram/ml), and four penicillin-resistant (MIC of 2.0 to 4.0 micrograms/ml) strains of pneumococci: 6 of 10 strains were resistant to macrolides (MICs of > or = 0.5 microgram/ml). MICs of RP 59500 (0.5 to 1.0 microgram/ml), RPR 106972 (0.125 to 0.25 microgram/ml), and pyostacine (0.125 to 0.25 microgram/ml) did not alter with the strain's penicillin or macrolide susceptibility status. Three penicillin-susceptible strains and one penicillin-intermediate strain were susceptible to macrolides (MICs of < or = 0.25 microgram/ml); the macrolide MICs for the remaining strains were > or = 4.0 micrograms/ml. Cefotaxime MICs rose with those of penicillin G, but all strains were inhibited at MICs of < or = 2.0 micrograms/ml. RP 59500 was bactericidal for all strains after 24 h at 2 x MIC and yielded 90% killing of all strains at 6 h at 2 x MIC; at 8 x MIC, RP 59500 showed 90% killing of six strains within 10 min (approximately 0.2 h). In comparison, RPR 106972 was bactericidal for 9 of 10 strains at 2 x MIC after 24 h and yielded 90% killing of all strains at 2 x MIC after 6 h; 90% killing of six strains was found at 8 x MIC at 0.2 h. Results for pyostacine were similar to those of RPR 106972. Erythromycin and clarithromycin were bactericidal for three of four macrolide-susceptible strains after 24 h at 4 x MIC. Clarithromycin yielded 90% killing of three strains at 8 x MIC after 12 h. Cefotaxime was bactericidal for all strains after 24 h at 4 x MIC, yielding 90% killing of all strains after 6 h at 4 x MIC. All three streptogramins yielded rapid killing of penicillin- and erythromycin-susceptible and -resistant pneumococci and were the only compounds which killed significant numbers of strains at 0.2 h.
Experiences of Adults With Type 1 Diabetes Using Glucose Sensor–Based Mobile Technology for Glycemic Variability: Qualitative Study (2019)

Results suggest that Sugar Sleuth can be an effective educational tool to enhance both patient-clinician collaboration and diabetes self-management. Findings also highlight the importance of exploring psychosocial and socioeconomic factors that may advance the understanding of PWDs' individual differences when using glycemic technology and may promote the development of customized mobile tools to improve diabetes self-management.
The search for new pasture plants to achieve more sustainable production systems in southern Australia (2008)

Increasing the proportion of the landscape planted to deep-rooted perennial pasture species is recognised as one of several remedial actions required for the control of dryland salinity in southern Australia. The widespread use of perennials in farming systems is limited at present by the lack of well-adapted perennials that can be grown to reduce recharge in a landscape where drought, soil acidity, temporary waterlogging, infertile soils and unrestricted grazing prohibit the use of many species. The range of plants adapted to salinity also needs to be expanded to stabilise and ameliorate soils already degraded by rising watertables and to increase the profitability of grazing discharge regions within the landscape. This paper describes the steps involved in a national forage screening and breeding program initiated by the Cooperative Research Centre (CRC) for Plant-based Management of Dryland Salinity1, seeking to expand the range of perennial and or salt-tolerant forage plants that can be incorporated into farming systems of southern Australia. It describes the target environments, soil constraints, farming systems and the criteria being considered when assessing the potential of new plants, including assessment of the weed risk posed by introducing new species. This paper forms an introduction to a special issue which presents the outcomes of the pasture species field evaluation and plant breeding program conducted by the CRC.
In Response (2011)

Dr. Mazoit has raised excellent questions,1 and I am happy to address his concerns: Dr. Mazoit's description of the Langendorff preparation in multiple manuscripts is not plagiarism, because it is his description. If he has used exactly the same preparation in each study, then he should describe it using exactly the same words in each manuscript. If he changes the description in each manuscript, readers will wonder what change in methodology prompted the change in wording. Of course, if he is using someone else's description, that is also fine, but it must be properly referenced. If a Chinese scientist wishes to publish a paper in Chinese and subsequently in English, then the author must make an explicit disclosure of the prior publication and provide written permission from the copyright holder. This is explained in our Guide for Authors. If this is not done, then unfortunately the second publication represents a duplicate publication, and is also a copyright violation (at least under United States law). There are numerous examples of guidelines being published in multiple journals, including Anesthesia & Analgesia. This is not plagiarism or duplicate publication, as long as the guidelines state that they will appear in multiple publications. The title of the editorial, “You Will Be Caught,”2 was intended to inspire some anxiety, because it is true. Everyone uses “cut and paste,” and as a result everyone is at risk for plagiarism. It has nothing to do with native language. Powerful tools to detect plagiarism have been created, and they are readily available. If a reader or academic competitor detects plagiarism in a published manuscript, it can be a nightmare for the authors. If I detect it on submission, then I can help authors fix the problem before it gets published. That is the goal. Steven L.

Adaline Based Control of Solid State Voltage Regulator for Isolated Asynchronous Generators (2006)

This paper deals with the adaline based control of a solid state voltage regulator (SSVR) for isolated asynchronous generator (IAG). With indirect current control, proposed control scheme uses a fast adaptive linear element (adaline) based neural network reference current extractor, which extracts the real positive sequence current component without any phase shift. The estimation of the reference current through adaline utilizes LMS (Least Means Squire) algorithm to maintain online calculation of weights. A closed loop PI (Proportional-Integral) controller is used for regulating the DC bus of SSVR. The control scheme is verified for regulating the voltage of an isolated asynchronous generator in constant speed variable power application through simulation in MATLAB using Simulink and PSB (power system block) toolboxes.
Conversion of human and mouse fibroblasts into lung-like epithelial cells (2019)

Cell lineage conversion of fibroblasts to specialized cell types through transdifferentiation may provide a fast and alternative cell source for regenerative medicine. Here we show that transient transduction of fibroblasts with the four reprogramming factors (Oct4, Sox2, Klf4, and c-Myc) in addition to the early lung transcription factor Nkx2-1 (also known as Ttf1), followed by directed differentiation of the cells, can convert mouse embryonic and human adult dermal fibroblasts into induced lung-like epithelial cells (iLEC). These iLEC differentiate into multiple lung cell types in air liquid interface cultures, repopulate decellularized rat lung scaffolds, and form lung epithelia composed of Ciliated, Goblet, Basal, and Club cells after transplantation into immune-compromised mice. As proof-of-concept, differentiated human iLEC harboring the Cystic Fibrosis mutation dF508 demonstrated pharmacological rescue of CFTR function using the combination of lumacaftor and ivacaftor. Overall, this is a promising alternative approach for generation of patient-specific lung-like progenitors to study lung function, disease and future regeneration strategies.

Urinary bladder function in conscious rat pups: a developmental study (2012)

Cystometric studies of bladder function in anesthetized neonatal rats have suggested specific changes in urodynamic parameters that coincide with the development of a mature bladder-to-bladder micturition reflex. Here, we used a conscious cystometry model that avoids the potentially confounding effects of anesthesia to characterize voiding patterns and urodynamic parameters during early postnatal development in healthy rat pups. Cystometry was performed on postnatal day (P)0, 3, 7, 14, and 21 rats with continuous intravesical instillation of NaCl via a bladder catheter. Micturition cycles were analyzed with respect to voiding pattern, nonvoiding contractions, infused volume, and basal, filling, threshold, and micturition pressures. Reproducible micturition patterns were obtained from all age groups. The time from stimulation to contraction was significantly longer (P ≤ 0.001) in ≤1-wk-old rats (∼10 s) than that in older rats (∼3 s). An interrupted voiding pattern was observed in ≤10-day-old subgroups. Micturition pressure progressively increased with age (from 21.77 ± 1.92 cmH(2)O at P0 to 35.47 ± 1.28 cmH(2)O at P21, P ≤ 0.001), as did bladder capacity. Nonvoiding contractions were prominent in the P3 age group (amplitude: 4.6 ± 1.3 cmH(2)O, frequency: ∼4.0 events/100 s). At P7, the pattern of spontaneous contractions became altered, acquiring a volume-related character that persisted in a less prominent manner through P21. Bladder compliance increased with age, i.e., maturation. In conclusion, conscious cystometry in rat pups resulted in reproducible micturition cycles that yielded consistent data. Our results revealed immature voiding and prolonged micturition contractions during the first 10 neonatal days and provide evidence for age-related changes in urodynamic parameters.

Boltzmannn Weighted Selection Improves Performance of Genetic Algorithms (1991)

Modifiable Boltzmann selective pressure is investigated as a tool to control variability in optimizations using genetic algorithms. An implementation of variable selective pressure, modeled after the use of temperature as a parameter in simulated annealing approaches, is described. The convergence behavior of optimization runs is illustrated as a function of selective pressure; the method is compared to a genetic algorithm lacking this control feature and is shown to exhibit superior convergence properties on a small set of test problems. An analysis is presented that compares the selective pressure of this algorithm to a standard selection procedure.
Chemical changes in sea water off Plymouth during 1958 (1960)

Analyses of sea water collected during 1958 at the International Hydrographic Station E1 (lat. 50° 02′ N., long. 4° 22′ W.) are given here in the same form as in earlier reports (Armstrong, 1954, 1955, 1957, 1958; Armstrong & Butler, 1959). The methods of collection and analysis remain the same. Salinities were determined by the Government Chemist, Department of Scientific and Industrial Research. We wish again to thank Lt.-Cdr. C. A. Hoodless, D.S.C., and the crew of R.V. ‘Sarsia’, and Capt. W. J. Creese and the crew of R.V. ‘Sula’ for help at sea.
Study of the human body radar signature variability based on computer models (2010)

This paper investigates the variability of the human body radar signature, for both stationary targets (where we are interested in the radar cross section) and moving targets (where we are interested in the Doppler response). The approach in this paper introduces both mesh distortions and variable walking patterns, in order to predict changes in the radar signature induced by morphological changes in the human meshes. The study is based entirely on computer simulations. We start with a basic human mesh and use the Maya software package to articulate or distort the model. Realistic human motion animation is obtained by using spatial coordinates from real motion capture data. The radar signature is obtained by running a Finite Difference Time Domain-based electromagnetic solver. Results are presented as radar cross section for stationary targets or Doppler spectrograms for moving targets.
[Production of fibronectin and PGE2 by cultured human alveolar macrophages]. (1989)

Production of fibronectin (Fn) and prostaglandin E2 (PGE2) by human alveolar macrophages (AM) which were obtained by bronchoalveolar lavage was studied in vitro. AM obtained from patients with idiopathic interstitial pneumonia (IIP) produced much more Fn than those from normal volunteers but produced less amounts of PGE2. We also tested the effect of lipopolysaccharide (LPS), phorbol 12-myristate 13-acetate (PMA), zymosan and albumin-anti albumin complex (alb-anti alb) on production of Fn and PGE2 from AM. LPS, PMA and zymosan suppressed Fn production but stimulated PGE2 production by AM from patients with IIP but indomethacin reversed the suppressive effect of LPS, PMA and zymosan on Fn production. On the contrary, alb-anti alb stimulated Fn production by AM. Furthermore, exogenous PGE2 suppressed Fn production by AM from patients with IIP in a dose-dependent manner. These data suggest that Fn production by AM may be changed by different stimuli or different states of disease, and there is close relationship between the production of Fn and PGE2 by AM.
