Deeply-towed underwater vehicle systems : a verified analytical procedure for creating parameterized dynamic models (1989)

The dynamics of deeply-towed cable/vehicle systems are governed by nonlinear partial differential equations and as a result, trajectory control is generally difficult using the available techniques. This work examines the possibility of utilizing parametric dynamic models in differential equation form, to present a far more tractable controls problem. A learning-model method for generating accurate approximations of this type is used, and the identification process is unique in that an analytically-based model provides the primary data sets, allowing for a priori characterization of system responses without using any real data. The performances of the parametric forms are then verified through comparison of model output against actual sea data obtained during recent cruises in the Caribbean and Mediterranean Seas. The respective merits and limitations of several different model structures are discussed, with respect to both pure performance and identification efficiency.
Efficient OFDM transmission without cyclic prefix over frequency-selective channels (2002)

We introduce a computationally efficient OFDM transmission technique that does not require a cyclic prefix and thus provides high spectral efficiency. The intersymbol interference (ISI) due to time dispersion of the channel is combated by ISI cancellation. We show that the inversion of the channel matrix for interchannel interference (ICI) cancellation can be done by the "operator perturbation technique" (OPT) much more efficiently than by conventional equation solvers. We supplement the OPT by blind techniques and hence reduce the error floor to zero for frequency-selective channels. The expense for a 2 Mbit/s transmission is about 500 MFlops. The technique can also deal with time-varying channels in a straightforward way.
Wideband Reconfigurable Printed Dipole Antenna with Harmonic Trap (2006)

Reconfigurable antennas have received a great deal of attention for their applications in wireless communications in recent years. They can be used for changing the operation frequency [1]-[6] or changing the radiation pattern [7]-[9]. In [1] a reconfigurable microstrip antenna was designed by placing MEMS series switches at the radiating edge. The series switches connect extra sections of transmission line to the microstrip antenna, thereby lowering its resonant frequency. In [2] a micromachined membrane was used as the ground plane below the microstrip patch antenna to design a frequency-agile patch antenna. In [3] a square patch antenna with switchable slots was proposed for dual band circular polarization operation. A dual band dipole using series MEMS switches was presented in [4] and a dual band reconfigurable Yagi antenna in [5]. A single-fed resonant slot, loaded with a series of PIN diodes switches, was designed in [6]. In [7] it was shown that by using RF switches the radiation pattern of the Hilbert curve fractal antenna could be made adaptively reconfigurable and also resonance frequency of the antenna was tunable by using the switches. In [8] a beam-switched Rhombic antenna was proposed. In [9] a reconfigurable single turn square microstrip spiral antenna was presented which can be reconfigurable in radiation pattern and frequency.

Demonstration of anticoagulation patient self-testing feasibility at an Indian Health Service facility: A case series analysis (2013)

Although anticoagulation guidelines now emphasize patient self-management (PSM) only, optimal PST remains an integral process in PSM delivery. In the patients studied, the results of this analysis suggest that PST at the IHS facility provided a convenient, alternative method for management of chronic warfarin therapy for qualified patients. More than half of the patients demonstrated improvement in TTR. Although there is a learning curve immediately following PST initiation, the mean TTR for the entire PST period increased modestly when compared to the time period prior to PST.
Path sensitization in critical path problem (logic circuit design) (1993)

An important aspect of the critical path problem is deciding whether a path is sensitizable. Three new path sensitization criteria are proposed in a general framework. Other path sensitization criteria can be presented in the same framework, enabling them to be compared with each other. An approximate criterion is also proposed and used to develop an efficient critical path algorithm for combinational circuits.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">></ETX>
Characterization of a Glutamate Transporter Operon, <i>glnQHMP</i> , in <i>Streptococcus mutans</i> and Its Role in Acid Tolerance (2009)

Glutamate contributes to the acid tolerance response (ATR) of many Gram-negative and Gram-positive bacteria, but its role in the ATR of the oral bacterium Streptococcus mutans is unknown. This study describes the discovery and characterization of a glutamate transporter operon designated glnQHMP (Smu.1519 to Smu.1522) and investigates its potential role in acid tolerance. Deletion of glnQHMP resulted in a 95% reduction in transport of radiolabeled glutamate compared to the wild-type UA159 strain. The addition of glutamate to metabolizing UA159 cells resulted in an increased production of acidic end products, whereas the glnQHMP mutant produced less lactic acid than UA159, suggesting a link between glutamate metabolism and acid production and possible acid tolerance. To investigate this possibility, we conducted a microarray analysis with glutamate and under pH 5.5 and pH 7.5 conditions which showed that expression of the glnQHMP operon was downregulated by both glutamate and mild acid. We also measured the growth kinetics of UA159 and its glnQHMP-negative derivative at pH 5.5 and found that the mutant doubled at a much slower rate than the parent strain but survived at pH 3.5 significantly better than the wild type. Taken together, these findings support the involvement of the glutamate transporter operon glnQHMP in the acid tolerance response in S. mutans.
Novel Hardware Architecture for Implementing the Inner Loop of the SHA-2 Algorithms (2011)

Cryptographic algorithms are used to enable security services that are the core of modern communication systems. In particular, Hash functions algorithms are widely used to provide services of data integrity and authentication. These algorithms are based on performing a number of complex operations on the input data, thus it is important to count with novel designs that can be efficiently mapped to hardware architectures. Hash functions perform internal operations in an iterative fashion, which open the possibility of exploring several implementation strategies. In the paper, two different schemes to improve the performance of the hardware implementation of the SHA-2 family of algorithms are proposed. The main focus of the proposed schemes is to reduce the critical path by reordering the operations required at each iteration of the algorithm. Implementation results on an FPGA device show an improvement on the performance on the SHA-256 algorithm when compared against similar previously proposed approaches.
The chimeric antibody chLpMab-7 targeting human podoplanin suppresses pulmonary metastasis via ADCC and CDC rather than via its neutralizing activity (2015)

Podoplanin (PDPN/Aggrus/T1α) binds to C-type lectin-like receptor-2 (CLEC-2) and induces platelet aggregation. PDPN is associated with malignant progression, tumor metastasis, and poor prognosis in several types of cancer. Although many anti-human PDPN (hPDPN) monoclonal antibodies (mAbs), such as D2-40 and NZ-1, have been established, these epitopes are limited to the platelet aggregation-stimulating (PLAG) domain (amino acids 29-54) of hPDPN. Recently, we developed a novel mouse anti-hPDPN mAb, LpMab-7, which is more sensitive than D2-40 and NZ-1, using the Cancer-specific mAb (CasMab) method. The epitope of LpMab-7 was shown to be entirely different from that of NZ-1, a neutralizing mAb against the PLAG domain according to an inhibition assay and lectin microarray analysis. In the present study, we produced a mouse-human chimeric anti-hPDPN mAb, chLpMab-7. ChLpMab-7 showed high antibody-dependent cellular cytotoxicity (ADCC) and complement-dependent cytotoxicity (CDC). Furthermore, chLpMab-7 inhibited the growth of hPDPN-expressing tumors in vivo. Although chLpMab-7 recognizes a non-PLAG domain of hPDPN, it suppressed the hematogenous metastasis of hPDPN-expressing tumors. These results indicated that chLpMab-7 suppressed tumor development and hematogenous metastasis in a neutralization-independent manner. In conclusion, hPDPN shows promise as a target in the development of a novel antibody-based therapy.
Resonance fluorescence from an atom in a squeezed vacuum (1987)

The fluorescent spectrum for a two-level atom which is damped by a squeezed vacuum shows striking differences from the spectrum for ordinary resonance fluorescence. For strong coherent driving fields the Mollow triplet depends on the relative phase of the driving field and the squeezed vacuum field. The central peak may have either subnatural linewidth or supernatural linewidth depending on this phase. The mean atomic polarization also shows a phase sensitivity.
Investigation of the Two-dimensional Performance of Supersonic Impulse Turbine Blade Cascades : 2nd Report, Flow and Losses in Blade Passage and Some Design Criteria (1984)

The efficiency of supersonic blade cascades for an impulse turbine designed by the conventional methods is not so high as expected because of the boundary layer separation. In this investigation, for improvement of the efficiency of the supersonic blade cascade, some important problems, such as accurate prediction of the starting Mach number and prevention of the boundary layer separation, are discussed based on the measurements and analysis of the flow in the blade passages designed by the free vortex flow method, which is one of the conventional methods. As the result, some design criteria are proposed.
Allosteric Binding of K+ to Crown Ether Macrocycles Appended to a Lanthanum Double Decker System (2001)

Abstract A benzocrown-appended lanthanum(III) porphyrin double decker has been synthesized which is capable of binding simple K+ in a cooperative, allosteric fashion to form a 1 : 4 complex. Analysis of this system by means of the Hill equation gave an overall binding constant (Kb) of 1.0 × 1014 (mol dm−3)−4 and a Hill coefficient of 4.0. This same system, however, binds Na+ in a conventional, linear fashion. These results indicate that the novel allosteric binding occurs as the result of 1 : 2 sandwich complexes between K+ and appended crown ether moieties of the two joined porphyrins. The suitability of lanthanum(III) over cerium(IV) for preparing this highly crowded double decker porphyrin is also noted.
Fractionation by Ultracentrifugation of Gram Negative Cytoplasmic and Membrane Proteins (2014)

Protein fractionation is a useful separation process which divides membrane proteins (including those located in the outer and inner membrane) and cytoplasmic proteins into discrete fractions. Fractionation of proteins can simplify analysis of the numbers of proteins present, and therefore make easier to characterize any environmentally or mutation induced changes in expression profiles, or changes in protein strucutre resulting from post-translational modification. This protocol is derived from Haigh et al. (2013) and it is specific to Gram negative bacteria.
Mechanics Modeling of Blade/Disk Contacts (2005)

A predictive procedure capable of calculating dovetail surface contact loads in gas turbine engines is developed. The procedure determines contact normal and tangential loads, for a complete mission involving radial blade and thermal loads. Once Finite Element calculations to determine empirical constants for a specific blade/disk geometry are completed, the predictive procedure handles complicated load histories in near real-time for both single and double tang dovetails. The resulting load histories can be combined with Singular Integral Equations to calculate edge-of-contact stresses. The resulting contact stresses have been used to successfully predict fretting fatigue lives under controlled laboratory conditions.
Intermittent Androgen Suppression for Rising PSA Level After Radiotherapy (2013)

Androgen deprivation with medical castration has been the mainstay treatment for metastatic prostate cancer. However, there are several drawbacks to prolonged androgen deprivation, including development of tolerance (loss of androgen dependence) and adverse effects on the quality of life. In mice tumor models of androgen dependence, castration followed by re-exposure to androgens before tumor progression preserved androgen dependence. The possible value of this treatment strategy has been studied in human prostate cancer. Several phases 2 and 3 clinical studies suggest that intermittent androgen deprivation can delay hormone resistance and provide a quality-of-life benefit. This noninferiority randomized trial compared overall survival of prostate cancer patients with use of intermittent and continuous androgen deprivation. Enrolled patients had prostatic adenocarcinoma but no metastatic disease and a rising prostate-specific antigen (PSA) level greater than 3 ng/mL after primary or salvage radiotherapy for localized prostate cancer more than 12 months before enrollment. Intermittent androgen-deprivation therapy consisted of 8-month treatment cycles, with nontreatment periods based on the PSA level. The primary study end point was overall survival. Secondary end points included time to castration-resistant disease, quality of life, and duration of nontreatment intervals. Participants were randomly assigned to intermittent therapy (n = 690) or continuous therapy (n = 696). The median follow-up was 6.9 years. No significant between-group differences in adverse events were found. With intermittent therapy, there was full testosterone recovery in 35% of patients and recovery to the trial-entry threshold in 79%. Intermittent therapy was associated with improvements in physical function and other quality-of-life measurements for hot flashes, urinary problems, fatigue, libido, and erectile function. A total of 524 patients died: 268 in the intermittent-therapy group and 256 in the continuous-therapy group. There was no difference between groups in median overall survival: 8.8 years in the intermittent-therapy group and 9.1 years in the continuous-therapy group; the hazard ratio for death was 1.02, with a 95% confidence interval of 0.86 to 1.21. With respect to the disease-specific survival, the estimated 7-year cumulative disease-related death rates were 18% in the intermittent group and 15% in the continuous group (P = 0.24). These findings show that, for overall survival, intermittent androgen deprivation is not noninferior to continuous therapy. Improvements in some quality-of-life factors are observed with intermittent therapy.
Anderson localization of matter waves (2009)

The transport of quantum particles in non ideal material media is strongly affected by scattering from impurities of the medium. Even for a weak disorder, semi-classical theories, such as those based on the Boltzmann equation for matter-waves scattering from the impurities, often fail to describe transport properties and full quantum approaches are necessary. The properties of the quantum systems are of fundamental interest as they show intriguing and non-intuitive phenomena that are not yet fully understood. Understanding quantum transport in amorphous solids is one of the main issues in this context, related to electric and thermal conductivities.
Biodegradable Mitral Annuloplasty for Congenital Ischemic Mitral Regurgitation (2009)

An anomalous origin of the left coronary artery from the pulmonary artery (ALCAPA) is associated with ischemic mitral regurgitation through a combination of papillary muscle ischemia or permanent fibrosis, left ventricular free wall ischemic dyskinesis and left ventricular dilatation. We report the successful management of a 27-month-old girl with ALCAPA and severe mitral regurgitation using a biodegradable mitral annuloplasty ring. It could represent a novel tool for mitral valve repair in ALCAPA-associated ischemic mitral regurgitation.
Artificial Intelligence Based Estimation of Water Saturation Using Electrical Measurements Data in a Carbonate Reservoir (2015)

Abstract Good estimation of water saturation is necessary for successful estimation of reservoir properties as it minimizes the error in initial oil-in-place calculations. Electrical measurements on core plugs have been used to predict water saturation by analyzing the parameters of Archie's equation. Presently, several methods such as conventional, CAPE (1, m, n), CAPE (a, m, n) and 3D methods have been used to analyze the parameters. However, the accuracy of these methods has become inadequate for optimal estimations. Recent successful applications of Artificial Intelligence (AI) techniques in petroleum engineering have confirmed the capability of AI to handle such non-linear and complex industrial problems. Interestingly, the new paradigm of employing AI for water saturation estimation has not been sufficiently addressed in the petroleum engineering technology application literature. This study focuses on the use of the predictive capabilities of Artificial Neural Networks and the Fuzzy Inference Engine. 378 data samples obtained from the laboratory measurements of electrical properties of 41 core plugs taken from Carbonate reservoir rocks in the Middle East were used for the implementation of the proposed techniques. Using the popular stratified data sampling method, 70% of the data points were used to train the AI models while the remaining 30% were used for validation and testing. The comparative results showed that the AI models performed better with higher accuracy and lower errors than those obtained with the current methods. Based on this result, we conclude that Fuzzy Logic exhibits a robust predictive capability for the estimation of water saturation from electrical measurements by providing a good match with the core values and giving better error distribution than the other AI and current methods.
Three-dimensional terahertz interferometric imaging system for concealed object detection (2010)

The paper presents a three-dimensional imaging system for concealed object detection. The system uses interferometric imaging at terahertz frequencies. A three-dimensional spiral antenna array is used as the detection array. The data is collected at one array location at a time using an element that moves along the 3-D array line in order to prevent blockage. The data is processed using an accelerated computation hardware that matches the speed of the array element movement, and produces the image in real time. The system is simulated to show its advantage over the 2-D imaging system. An experiment is set to prove the concept.
Evaluation of efficacy and biocompatibility of a novel semisynthetic collagen matrix as a dural onlay graft in a large animal model (2011)

Semisythetic collagen matrices are an attractive alternative in duraplasty due to their easy handling, lower surgical time, and high biocompatibility.
Antagonistic and synergistic peptide analogs of the tridecapeptide mating pheromone of Saccharomyces cerevisiae (1992)

Biologically inactive, truncated analogues of the Saccharomyces cerevisiae alpha-mating factor (WHWLQLKPGQPMY) either antagonized or synergized the activity of the native pheromone. An amino-terminal truncated pheromone [WLQLKPGQP(Nle)Y] had no activity by itself, but the analogue acted as an antagonist by competing with binding and activity of the mating factor. In contrast, a carboxyl-terminal truncated pheromone [WHWLQLKPGQP] was not active by itself nor did the peptide compete with alpha-factor for binding to the alpha-factor receptor, but it acted as a synergist by causing a marked increase in the activity of alpha-factor. The observation that residues near the amino terminus may be involved in signal transduction whereas those near the carboxyl terminus influence binding allows us to separate binding and signal transduction in the yeast pheromone response pathway. If found for other hormone-receptor systems, synergists may have potential as therapeutic compounds.
Experimental Verification and Comparison of MAFC Method and D-Q Method for Selective Harmonic Detection (2006)

This paper reviews two popular harmonic detection methods for power electronics applications. One is a d-q method, which dominates the three-phase active filter and STATCOM applications and the other one is a multiple adaptive feed forward cancellation (MAFC) method. The latter one is also called an adaptive neuron method, neural network method or Adaline method. The novelty of this paper is that it presents experimental results, which is rare in the literature. This paper first gives an introduction of MAFC method from adaptive control point of view. Then realtime (RT) implementation of two methods is introduced and realtime hardware in the loop tests (HIL) are fully performed to compare these two methods. Finally, experimental results using these two methods on a diode rectifier front end motor drive and a thyristor rectifier dc drive are presented. Both steady state and dynamic performances of these two methods are compared. The comparison results give guidance for using these two methods for power electronics applications like active filter or STATCOM
