Fabrication of superconducting delay line with GaAs Schottky diode (1999)

We improved the fabrication process of superconductor/semiconductor devices based on epitaxial liftoff (ELO) technology by using polyimide film in place of Apiezon wax. We investigated the process conditions and fabricated basic GaAs devices. We also succeeded in bonding a GaAs Metal-Semiconductor-Metal photodiode on YBCO micro-strip-line that is formed on an SrTiO/sub 3/ substrate. The basic characteristics of this photodiode are measured and the results have confirmed that the ELO process using polyimide film is feasible for fabricating superconductor/semiconductor functional devices.
Power Factor and Unbalance on a Polyphase System (1920)

In a single-phase or balanced polyphase circuit, the two factors which are contributory to power factors less than unity are wave distortion and phase displacement between current and voltage. In the paper the influence of wave shape is not considered, since in most large modern systems the wave form is nearly sinusoidal. The paper covers balanced and unbalanced polyphase systems without neutral current.
Vehicle Speed Estimation Using Acoustic Wave Patterns (2008)

We estimate a vehicle's speed, its wheelbase length, and tire track length by jointly estimating its acoustic wave pattern with a single passive acoustic sensor that records the vehicle's drive-by noise. The acoustic wave pattern is determined using the vehicle's speed, the Doppler shift factor, the sensor's distance to the vehicle's closest-point-of-approach, and three envelope shape (ES) components, which approximate the shape variations of the received signal's power envelope. We incorporate the parameters of the ES components along with estimates of the vehicle engine RPM, the number of cylinders, and the vehicle's initial bearing, loudness and speed to form a vehicle profile vector. This vector provides a <i xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">fingerprint</i> that can be used for vehicle identification and classification. We also provide possible reasons why some of the existing methods are unable to provide unbiased vehicle speed estimates using the same framework. The approach is illustrated using vehicle speed estimation and classification results obtained with field data.
An optimized ultrasound digital beamformer with dynamic focusing implemented on FPGA (2014)

We present a resource-optimized dynamic digital beamformer for an ultrasound system based on a field-programmable gate array (FPGA). A comprehensive 64-channel receive beamformer with full dynamic focusing is embedded in the Altera Arria V FPGA chip. To improve spatial and contrast resolution, full dynamic beamforming is implemented by a novel method with resource optimization. This was conceived using the implementation of the delay summation through a bulk (coarse) delay and fractional (fine) delay. The sampling frequency is 40 MHz and the beamformer includes a 240 MHz polyphase filter that enhances the temporal resolution of the system while relaxing the Analog-to-Digital converter (ADC) bandwidth requirement. The results indicate that our 64-channel dynamic beamformer architecture is amenable for a low power FPGA-based implementation in a portable ultrasound system.
Dose esclation in radioimmunotherapy based on projected whole body dose (1994)

A variety of approaches have been utilized in conducting phase I radioimmunotherapy dose-escalation trials. Escalation of dose has been based on graded increases in administered mCi; mCi/kg; or mCi/m2. It is also possible to escalate dose based on tracer-projected marrow, blood or whole body radiation dose. We describe our results in performing a dose-escalation trial in patients with non-Hodgkin lymphoma based on escalating administered whole-body radiation dose. The mCi dose administered was based on a patient-individualized tracer projected whole-body dose. 25 patients were entered on the study. RIT with 131 I anti-B-1 was administered to 19 patients. The administered dose was prescribed based on the projected whole body dose, determined from patient-individualized tracer studies performed prior to RIT. Whole body dose estimates were based on the assumption that the patient was an ellipsoid, with 131 antibody kinetics determined using a whole-body probe device acquiring daily conjugate views of 1 minute duration/view. Dose escalation levels proceeded with 10 cGy increments from 25 cGy whole-body and continues, now at 75 cGy. The correlation among potential methods of dose escalation and toxicity was assessed. Whole body radiation dose by probe was strongly correlated with the blood radiation dose determined from sequential blood samplingmore » during tracer studies (r=.87). Blood radiation dose was very weakly correlated with mCi dose (r=.4) and mCi/kg (r=.45). Whole body radiation dose appeared less well-correlated with injected dose in mCi (r=.6), or mCi/kg (r=.64). Toxicity has been infrequent in these patients, but appears related to increasing whole body dose. Non-invasive determination of whole-body radiation dose by gamma probe represents a non-invasive method of estimating blood radiation dose, and thus of estimating bone marrow radiation dose.« less
Bulbocavernosus Reflex: Its Validity as a Diagnostic Test of Neurogenic Impotence (1989)

Measurement of the bulbocavernosus reflex is used widely to diagnose underlying neurogenic disorders in erectile dysfunction. A prolonged bulbocavernosus reflex latency (that is more than 45 msec.) or the absence of a reflex response of the bulbocavernosus muscles during electrical stimulation of the glans penis is considered a sign of neurological disease. Since only a few experimental studies have been performed in man related to the neurophysiological mechanism of erection, and since the results of these studies were contradictory the diagnostic validity of bulbocavernosus reflex measurement was reassessed. We determine whether men with abnormal bulbocavernosus reflex latencies have concomitant organic erectile dysfunction as confirmed by nocturnal plethysmographic and rigidity recordings. The bulbocavernosus reflex was recorded in 90 subjects and 19 had abnormal bulbocavernosus reflex latencies. Of these 19 subjects 8 had normal nocturnal erections, thus, confirming a diagnosis of psychogenic impotence. These results cast some doubts on the validity of bulbocavernosus reflex measurement for the diagnosis of organic erectile dysfunction due to a neurological disease.
The role of the ‘gearbox’ in the transcription of essential genes (1991)

Regulation of transcription occurs at different levels, one being in the presence of sequences specifically recognized by different forms of RNA polymerase, i.e. the promoters. Three different kinds of promoter are defined according, among other things, to their dependence on the growth rate of the cell: the 'house-keeper' promoter of many metabolic genes, the stringent promoter found at several rRNA and ribosomal protein genes, and the 'gearbox' at genes whose products are required at higher relative amounts at lower growth rates. The identified gearbox promoters of Escherichia coli share specific homologies in the -10, -35 and upstream regions. Although there may be different types of gearbox promoters, the -10 sequence of one of these promoters has been found to be essential for functioning as a gearbox. This suggests the existence of specific sigma factors for its transcription. RpoS (KatF) is a likely candidate for being one of these sigma factors. Computer simulation allows us to predict that such sigma factors should, in turn, be expressed following a gearbox mode, which would then imply the existence of self-regulated loops contributing to the expression of some genes of bacterial division.

A model for predicting flow regime transitions in horizontal and near horizontal gas‐liquid flow (1976)

Abstract Models are presented for determining flow regime transitions in two‐phase gas‐liquid flow. The mechanisms for transition are based on physical concepts and are fully predictive in that no flow regime transitions are used in their development. A generalized flow regime map based on this theory is presented.
The treadmill (1992)

A simple real-time garbage collection algorithm is presented which does not copy, thereby avoiding some of the problems caused by the asynchronous motion of objects. This in-place "treadmill" garbage collection scheme has approximately the same complexity as other non-moving garbage collectors, thus making it usable in a high-level language implementation where some pointers cannot be traced. The treadmill is currently being used in a Lisp system built in Ada.

Inactivation of Airborne Viruses by Ultraviolet Irradiation (1964)

Aerosolized viruses were passed through a high-intensity ultraviolet (UV) cell. This cell consisted of a long cylindrical aluminum tube [diameter, 7 in. (17.7 cm); length, 36 in. (91.4 cm)] with a highly reflective inner surface and a longitudinally extending helical baffle system which directed airborne particles in close proximity to a centrally located UV lamp. After having been passed through the UV cell, viral aerosols were collected with an Andersen sampler, and viral concentrations were determined by plaque assay methods on tissue cultures. Inactivation rates of greater than 99.9% were obtained for Coxsackie, influenza, Sindbis, and vaccinia viruses, and slightly less for adenovirus (96.8%), when the aerosols passed through the UV cell at 100 ft(3)/min. At aerosol flow rates of 200 ft(3)/min, inactivation rates were slightly lower; 91.3 for adenovirus, 97.5 and 96.7 for Coxsackie and Sindbis, respectively, and greater than 99.9% for influenza and vaccinia viruses.
Point cathodes for use in virtual source electron optics (1985)

SUMMARY A comparison is made for three point cathodes which are used in an electron gun forming a virtual rather than real source. The three cathodes operate in the field emission (FE), thermal‐field (TF) and Schottky emission (SE) regimes. A low angular intensity is chosen for this comparison, typical of an SEM as contrasted to an electron‐beam lithography system application. Energy spread, virtual source size and current fluctuations are compared.
Effect of Complexing Sodium Bentonite with Soybean Meal or Urea in Vitro Ruminal Ammonia Release and Nitrogen Utilization in Ruminants (1978)

Five in vitro rumen ammonia release experiments were conducted with combinations of nitrogen (N) sources and sodium bentonite (NaB). The first experiment demonstrated that complexes of NaB with either casein or soybean meal (SBM) resulted in reduced ammonia release. Urea (U) treated with NaB exhibited reduced ammonia release at 4 hr, but not at 24 hr of incubation. Further experiments showed that as the ratio of protein to NaB widened ammonia release increased. A SBM:NaB mixture that had been wetted and dried was more effective in reducing ammonia release than simply dry mixing the ingredients. Varying the pH of the water used in mixing SBM with NaB had little effect on ammonia release. A 3 × 2 factorial N balance trial was conducted (3 N sources, with and without NaB) to determine the N utilization of lambs fed high roughage diets supplemented with SBM, SBM + NaB, U, U + NaB, SBM + U and SBM + U + NaB. SBM treated with NaB with or without U resulted in nonsignificant increases in N retention. NaB significantly reduced ruminal ammonia concentration at 2 and 4 hr, but not at 1 hr postfeeding. A performance trial with individually-fed lambs tested the supplemental N sources of SBM, U, SBM + U, SBM + NaB (3:1 ratio) SBM + NaB (3:1 ratio) + U and SBM + NaB (1.5:1 ratio) + U. The SBM-supplemented lambs gained more and were more efficient than those supplemented with U. The SBM + U-fed lambs were intermediate between those fed SBM or U treatments. SBM treatments complexed with NaB, whether alone or in combination with urea, gained as rapidly and were as efficient as the SBM control. Steers supplemented with SBM + NaB + U gained more (P<05) than those fed SBM + U in a 112-day growing trial. These data show that complexing protein with NaB has a positive effect on N utilization in ruminants.
A Comparison of Silicon Wafer Etching by  KOH  and Acid Solutions (1989)

etching was investigated as a means of removing damage in place of acid etching. It was found to have advantages over acid etching for both the wafer user and the producer. For the wafer user, offered better device yield, flatter wafers, better back‐side geometry, and the avoidance of metal plating. For the wafer producer, offered a safer, lower cost, more compact and environmentally conservative process, better temperature control, and a more uniform and consistent appearance. Detailed etch rates were established.
Weapons of mass destruction: virulence factors of the global killer Enterotoxigenic<i>Escherichia coli</i> (2006)

Enterotoxigenic Escherichia coli (ETEC) is the most common cause of food and water-borne E. coli-mediated human diarrhoea worldwide. The incidence in developing countries is estimated at 650 million cases per year, resulting in 800 000 deaths, primarily in children under the age of five. ETEC is also the most common cause of diarrhoea among travellers, including the military, from industrialized nations to less developed countries. In addition, ETEC is a major pathogen of animals, being responsible for scours in cattle and neonatal and postweaning diarrhoea in pigs and resulting in significant financial losses. Studies on the pathogenesis of ETEC infections have concentrated on the plasmid-encoded heat-stable and heat-labile enterotoxins and on the plasmid-encoded antigenically variable colonization factors. Relatively little work has been carried out on chromosomally encoded virulence factors. Here, we review the known virulence factors of ETEC and highlight the future for combating this major disease.
Paramagnetic and Electric Quadrupole Hyperfine Interactions of Ferric Ions in Ice and FeCl3·6H2O (1968)

Mössbauer resonance in 57Fe has been used to study the species Fe(H2O)5Cl2+ and Fe(H2O)63+ in frozen aqueous solutions of ferric chloride and ferric nitrate. The spectral lines display pronounced broadening as the temperature is lowered, as a result of paramagnetic relaxation effects. In dilute samples at 4.2°K, resolved paramagnetic hyperfine structure was observed for both species and permitted identification of the lowest crystal-field states of the ferric ion. The effective magnetic fields originating from the | ± 52〉 Kramers doublets were determined as 553 kG in Fe(H2O)5Cl2+ and 588 kG in Fe(H2O)63+. The latter ion showed no evidence of an electric quadrupole interaction, whereas the former exhibited a significant quadrupole splitting due to the coordinated Cl− ligand. The apparent electronic relaxation in the pentaquo–chloro complex was found to be substantially faster than that in the hexaquo complex, which may be indicative of a smaller zero-field splitting in the former case or an unbalanced spin pairing in the Cl ion. Results are presented for crystalline FeCl3·6H2O, in which the ion Fe(H2O)4Cl2+ exists as a structural unit. These spectra exhibit unusual line shapes and temperature variations which can be qualitatively understood by considering the effects of paramagnetic relaxation on the hyperfine interactions. The study of FeCl3·6H2O and its frozen solutions also demonstrates that common features as well as differences between the ion complex in solution and in the salt crystal may be inferred from a comparison of the Mössbauer spectra.
[Characteristics of the ambulatory care of patients with complicated forms of dust-induced bronchitis]. (1993)

The efficacy of follow-up was evaluated in 83 patients facing complicated dust bronchitis of 2 and 3 grades. An active follow-up group was treated by immunopotentiators in clinic every 3-4 months so as to prevent recurrences, while the passive follow-up group received the stationary treatment only once a year. Observations within 3 years showed a great efficiency of the active follow-up combined with the antirecurrence treatment given 3-4 times a year. Immune status was stressed to improve in connection with the clinical relief.
Robust source signature deconvolution and the estimation of primaries by sparse inversion (2011)

The past few years had seen some concentrated interest on a particular wavefield‐inversion approach to the popular SRME multiple removal technique called Estimation of Primaries by Sparse Inversion (EPSI). EPSI promises greatly improved tolerance to noise, missing data, edge effect, and other physical phenomenon generally not described by the SRME relation (van Groenestijn and Verschuur, 2009a,b). It is based on the premise that it is possible to stably invert for both the primary impulse response and the source signature despite beforehand having no (or very limited) explicit knowledge of latter. The key to successful applications of EPSI, as shown in very recent works (Savels et al., 2010), is a robust way to reconstruct very sparse primary impulse response events as part of the inversion process. Based on the various successful demonstrations in literature, there is a very strong sense that EPSI will also play an important role in future developments of source signature deconvolution and the general recovering of wavefield spectrum.
Classification of Cardiotocogram Data using Neural Network based Machine Learning Technique (2012)

Cardiotocography (CTG) is a simultaneous recording of fetal heart rate (FHR) and uterine contractions (UC). It is one of the most common diagnostic techniques to evaluate maternal and fetal well-being during pregnancy and before delivery. By observing the Cardiotocography trace patterns doctors can understand the state of the fetus. There are several signal processing and computer programming based techniques for interpreting a typical Cardiotocography data. Even few decades after the introduction of cardiotocography into clinical practice, the predictive capacity of the these methods remains controversial and still inaccurate. In this paper, we implement a model based CTG data classification system using a supervised artificial neural network(ANN) which can classify the CTG data based on its training data. According to the arrived results, the performance of the supervised machine learning based classification approach provided significant performance. We used Precision, Recall, F-Score and Rand Index as the metric to evaluate the performance. It was found that, the ANN based classifier was capable of identifying Normal, Suspicious and Pathologic condition, from the nature of CTG data with very good accuracy.

Isolation and characterization of a Chinese hamster ovary (CHO) mutant defective in the second step of glycosylphosphatidylinositol biosynthesis (1996)

Mutant cell lines defective in the biosynthesis of glycosylphosphatidylinositol (GPI) described to date were isolated by selecting cells which no longer expressed one or more endogenous GPI-anchored proteins on their surface. In this study, a new mutant in this pathway was isolated from ethylmethane-sulphonate-mutagenized Chinese hamster ovary cells stably transfected with human placental alkaline phosphatase (PLAP) as a marker of GPI-anchored proteins. A three-step protocol was employed. In the first step, cells with decreased surface expression of PLAP were selected by four rounds of complement-mediated lysis with an anti-(alkaline phosphatase) antibody. The surviving cells were cloned by limiting dilution and those with low levels of total alkaline phosphatase activity were selected in the second step. Finally, the ability of each clone to synthesize the first three intermediates in GPI biosynthesis in vitro was assessed to determine which cells with low alkaline phosphatase activity harboured a defect in one of these reactions. Of 230 potential mutants, one was defective in the second step of GPI biosynthesis. Microsomes from this mutant, designated G9PLAP.85, were completely unable to deacetylate either endogenous GlcNAc-phosphatidylinositol (PI) synthesized from UDP[6-3H]GlcNAc or exogenous GlcNAc-PI added directly to the membranes. Complementation analysis with the Thy-1-deficient murine lymphoma cells demonstrated that G9PLAP.85 has a molecular defect distinct from these previously described mutants. Therefore, these results suggest that mutants in GPI biosynthesis could be selected from almost any cell line expressing a GPI-anchored marker protein.
