In Situ Processing of Ferroelectric Materials from Lead Waste Streams by Injection of Gas Phase Titanium Precursors: Laser Induced Fluorescence and X-ray Diffraction Measurements (1998)

Several industrial process exhaust gas streams contain enriched toxic metal species such as lead and cadmium. Gas phase sorbent precursor techniques have been developed to effectively capture these toxic metal species. This methodology is further extended to not only capture the toxic metal species, but produce useful materials. Injection of gas phase titanium precursors to reactively capture the lead species is proposed for the processing of ferroelectric lead titanate materials in enriched lead exhaust streams. Conditions to produce lead titanate in high temperature systems are established. Diagnostic techniques such as X-ray diffraction and laser induced fluorescence spectroscopy are used to determine optimal conditions to not only capture the lead species but also produce perovskite structured lead titanate. Such approaches can be extended to real combustor exhaust streams with high toxic metal concentrations such as lead smelters for effective environmental control and production of novel materials.
Design of new front-end electronics for animal PET (2003)

Highly pixilated detector modules for animal PET such as LSO-APD module require power-efficient, highly integrated and reliable front-end electronics. A new waveform sampling front-end chip for animal PET has been developed. The front-end electronics consist of a preamplifier, a variable gain amplifier (VGA) and a fast ADC per channel. The preamplifier picks up detector signals while the ADC samples the output signals of the preamplifier and converts them into digital waveforms. The VGA adjusts the signal amplitude to the maximum input range of the ADC. Digitizing the whole waveform on-chip would provide large flexibility for signal processing, e.g. the energy and time information can be extracted by either a simple linear interpolator or a more complex statistics estimator. The preamplifier, VGA and 6 bit 100 MSPS folding ADC have been designed using Rohm 0.35 /spl mu/m CMOS ASIC technology. Full custom ASIC technique allows us to integrate analog and digital circuits into one chip. The preamplifier occupies 180/spl times/100 /spl mu/m/sup 2/ and has a rise time of 22 ns while the VGA occupies 180/spl times/90 /spl mu/m/sup 2/ and have a variable gain from 3.6 to 25. The ADC occupies 0.24 mm/sup 2/ (excluding digital circuit), dissipates 1 W for 8 channels with a 3.3 V power supply and has a DNL of 0.7 LSB and INL of 1.4 LSB.

Effect of avalanche photodiode and thermal noises on the performance of binary phase‐shift keying‐subcarrier‐intensity modulation/free‐space optical systems over turbulence channels (2013)

In this study, the authors theoretically study the performance of direct‐detection free‐space optical communication systems using binary phase‐shift keying subcarrier‐intensity modulation and avalanche photodiode (APD). The system bit‐error rate and channel capacity are theoretically derived in cases of log‐normal and gamma‐gamma channel models for weak‐to‐moderate and moderate‐to‐strong atmospheric turbulence conditions, respectively. The authors quantitatively discuss the optimal values of the APD average gain, required transmitted optical power, and operating bit‐rate considering various turbulence conditions, APD shot noise and thermal noise. It is seen that, although the impact of turbulence is severe, a proper selection of APD average gain could significantly improve the system performance in both cases of turbulence channels. The optimal value of APD average gain remains almost the same for different levels of turbulence; nevertheless it varies significantly in accordance to the change of receiver noise temperature.
Urelumab alone or in combination with rituximab in patients with relapsed or refractory B‐cell lymphoma (2020)

Urelumab, a fully human, non-ligand binding, CD137 agonist IgG4 monoclonal antibody, enhances T-cell and natural killer-cell antitumor activity in preclinical models, and may enhance cytotoxic activity of rituximab. Here we report results in patients with relapsed or refractory diffuse large B-cell lymphoma (DLBCL), follicular lymphoma (FL), and other B-cell lymphomas, in phase 1 studies evaluating urelumab alone (NCT01471210) or combined with rituximab (NCT01775631). Sixty patients received urelumab (0.3 mg/kg IV Q3W, 8 mg IV Q3W, or 8 mg IV Q6W); 46 received urelumab (0.1 mg/kg, 0.3 mg/kg, or 8 mg IV Q3W) plus rituximab 375 mg/m<sup>2</sup> IV QW. The maximum tolerated dose (MTD) of urelumab was determined to be 0.1 mg/kg or 8 mg Q3W after a single event of potential drug-induced liver injury occurred with urelumab 0.3 mg/kg. Treatment-related AEs were reported in 52% (urelumab: grade 3/4, 15%) and 72% (urelumab + rituximab: grade 3/4, 28%); three led to discontinuation (grade 3 increased AST, grade 4 acute hepatitis [urelumab]; one death from sepsis syndrome [urelumab plus rituximab]). Objective response rates/disease control rates were 6%/19% (DLBCL, n = 31), 12%/35% (FL, n = 17), and 17%/42% (other B-cell lymphomas, n = 12) with urelumab and 10%/24% (DLBCL, n = 29) and 35%/71% (FL, n = 17) with urelumab plus rituximab. Durable remissions in heavily pretreated patients were achieved; however, many were observed at doses exceeding the MTD. These data show that urelumab alone or in combination with rituximab demonstrated manageable safety in B-cell lymphoma, but the combination did not enhance clinical activity relative to rituximab alone or other current standard of care.

Supercontinuum generation in an As2Se3-based chalcogenide PCF using four-wave mixing and soliton self-frequency shift (2009)

We theoretically find a bandwidth of 4 μm can be generated using four-wave mixing and soliton self-frequency shift in an As2Se3-based chalcogenide PCF with an air-hole-diameter-to-pitch ratio of 0.4 and a pitch of 3 μm.
Photodynamic Therapy of Tumors Can Lead to Development of Systemic Antigen-Specific Immune Response (2010)

Understanding the role of antigen-expression in PDT immune response may allow application of PDT in metastatic as well as localized disease. To the best of our knowledge, this is the first time that PDT has been shown to lead to systemic, antigen- specific anti-tumor immunity.
Investigation of modal processing for low frequency acoustic communications in shallow water (2008)

Acoustic receptions at a vertical line array collected during the SW06 experiment were processed to show the feasibility of broadband mode decomposition as a preprocessing method to shorten time-spread and concentrate received signal energy in a small number of independent channels. The vertical array spanned the water column from 12 m depth to the bottom. PSK m-sequence modulated signals with different carrier frequencies were transmitted from a distance of 19.2 km. Signals were processed for both the case of ordinary internal waves activity and the case with abnormally strong internal wave solitons. The measured sound velocity and known bottom properties were accounted for. Mode filtering was based on a broadband pseudo-inverse processing of the received VLA signals. The broadband mode filtering decomposed the received signal into a number of independent signals with a reduced time-spread. The constellation of signals from the output of mode filters showed that a simple demodulator can achieve a high quality reception. Even during strong internal waves activity the acoustic energy was concentrated in a small number of the first acoustical modes. The receiver estimated the mode-time intensity distribution and used the strongest modes for demodulation. High quality reception is demonstrated with the data.
Rociverine Citrate: A New Spasmolytic Agent, Potentially Useful in the Treatment of, Urinary Bladder Hyperreflexia (1986)

Rociverine citrate was evaluated for its ability to affect the motility of rat urinary bladder, in vitro and in vivo, in comparison with flavoxate hydrochloride. Rociverine counteracted both methacholine- and high K+-induced tonic contractions of bladder strips. In anaesthetized rats, intravenous rociverine inhibited dose-dependently frequency and amplitude of the distension-induced rhythmic contractions (DIRCs) of urinary bladder and counteracted the topical high K+-induced pressure increase in the same organ. Orally administered rociverine produced a dose-related reversal of the reserpine-induced detrusor hyperreflexia in anaesthetized rats. In each of these experimental models rociverine was more effective than flavoxate. These results point to the usefulness of rociverine in the treatment of urinary bladder motility disorders.

Security Governance for Enterprise VoIP Communication (2008)

Voice is, besides email, the major personal communication technology for businesses. As it is often used for sensitive conversations, an appropriate security level is of great relevance. Historically, security measures have either been targeted to prevent fraud, thereby securing the operatorpsilas business model, or to provide military-class end-to-end encryption. Neither approach targets the security objectives of enterprises using private and public voice communication for sensitive business exchanges. A graded approach to VoIP security for enterprise communication allows for a step-wise introduction of security features required for voice communication of different security levels similar to common data protection classes.
Viruses from extreme thermal environments (2001)

Viruses of extreme thermophiles are of great interest because they serve as model systems for understanding the biochemistry and molecular biology required for life at high temperatures. In this work, we report the discovery, isolation, and preliminary characterization of viruses and virus-like particles from extreme thermal acidic environments (70-92 degrees C, pH 1.0-4.5) found in Yellowstone National Park. Six unique particle morphologies were found in Sulfolobus enrichment cultures. Three of the particle morphologies are similar to viruses previously isolated from Sulfolobus species from Iceland and/or Japan. Sequence analysis of their viral genomes suggests that they are related to the Icelandic and Japanese isolates. In addition, three virus particle morphologies that had not been previously observed from thermal environments were found. These viruses appear to be completely novel in nature.
Alternative method for identifying reconstituted cells (1980)

Enucleation techniques combining mild centrifugation in the presence of cytochalasin B permit cells to be separated into nuclear fragments (karyoplasts) and cytoplasmic fragments (cytoplasts). These fragments, though stable for a short time, will ultimately degenerate by the procedures described in this report. One can, however, fuse cytoplasts to karyoplasts by using polyethylene glycol and obtain viable reconstituted cells whose properties may be useful for understanding some aspects of the nuclear-cytoplasmic interactions associated with tumorigenicity and steroidogenesis. However, the presence of cybrids, hybrids, and parental whole cell contaminants along with the reconstituted cell population make it necessary to have genetic markers that reside in both the nucleus and cytoplasm in order to preferentially identify reconstituted cells derived from a karyoplast fused to a cytoplast. By utilizing the Y-1 cell line, which is tumorigenic and responds to corticotropin by secreting steroids, and the AMT-BU-A1 (AMT) cell line, which is nontumorigenic and does not respond to corticotropin but has a nuclear marker, BrdUrd(r), and a cytoplasmic marker, CAP(r), we have reconstituted cells containing Y-1 karyoplasts and AMT cytoplasts. In this report we extend our previous techniques by describing an identification procedure that allowed us to isolate cells reconstituted from AMT karyoplasts fused to Y-1 cytoplasts. The results of these experiments support the concept that with these cell lines the nucleus (karyoplast) is ultimately sufficient to control the phenotypic expression or suppression of tumorigenicity and steroidogenesis.
Adaptive control of propofol-induced hypnosis in anesthesia using a minimally parameterized Wiener model (2012)

Many of the physical parameters influencing scores on the CKCUEST and the YBT-UQ are different. Common parameters influence the CKCUEST and ULRT scores, yet more parameters influence the CKCUEST score. We suggest the combined use of the CKCUEST and the YBT-UQ in overhead athletes.

Transglutaminase‐mediated methods for site‐selective modification of human growth hormone (2010)

Two methods for the site-selective modification of native human growth hormone (hGH) using microbial transglutaminase were developed. In the first method, 1,3-bisaminoxypropane was attached to hGH, providing a direct incorporation of reactive aminoxy groups for further modification. The reaction was shown to be selective for Gln(141), with minor modification at Gln(40). In the second method, modified glutamine substrates were developed for attachment to Lys(145) in hGH. A series of glutamine-substrates were screened, and it was shown that microbial transglutaminase was selective towards substitutions on the glutamine core structure. Products from both methods could be transformed to site selectively mono-PEGylated hGH-derivatives in good isolated yield.
Enhanced performance of microbolometer using coupled feed horn antenna (2001)

In the paper, we improved the performance of the microbolometer using coupled feed horn antenna. The response time of the device was improved by reducing thermal time constant as the area of the absorption layer was reduced. We designed the shape of an absorption layer as circular structure in order to reduce the coupling loss between the antenna and the bolometer. A supporting leg for thermal isolation also has circular structure and its length increased up to 82micrometers , it reduced the thermal conductance to 4.65x 10<SUP>-8</SUP>[W/K]. The directivity of the designed antenna has 20.8dB. So the detectivity of the bolometer was improved to 2.37x 10<SUP>-9</SUP> [cm ROOT(Hz)/W] as the noise characteristics of the bolometer was enhanced by coupling feed horn antenna. The fabrication of the bolometer are carried out by a surface micromachining method that uses a polyimide as a sacrificial layer. The absorption layer material of the bolometer is VO<SUB>x</SUB> and its TCR value has above 2%/K. The 3-D feed horn antenna structure can be constructed by using a PMER negative photoresist. The antenna and the bolometer can be bonded by Au-Au flip chip bonding method.
Tailoring quaternized starch as a non‐viral carrier for gene delivery applications (2014)

ABSTRACT Non‐viral gene delivery systems have become increasingly desirable in both basic research and clinical settings as they overcome some of the problems associated with viral vectors. Presently, non‐viral carriers used for gene transfer consist mostly of liposomal formulations and cationic polymers. Starch, which is a biodegradable, biocompatible, non‐toxic, and water soluble polysaccharide, was evaluated for its potential as a non‐viral gene delivery carrier, after modifying it to cationic starch (Q‐starch) by means of quaternization. Q‐starch synthesis was assessed by means of nuclear magnetic resonance, Fourier transform infrared spectroscopy, elemental analysis, and Kjeldahl method, demonstrating that all the chemical reactions occurred. The Q‐starch potential to condense pDNA was evaluated by gel electrophoresis, dynamic light scattering, atomic force microscopy, and zeta potential, validating the formation of nano‐sized, positively charged spherical complexes. Transfection efficiency experiments reveal that there are two barriers for efficient transfection: endosomal escape and complex de‐complexation, while the latter appears to be the rate‐limiting step. We propose that further improvement in transfection efficiency can be achieved by augmenting carrier lysosomotropic ability, as well as its ability to disconnect from the pDNA.

A primary-switched line-side converter using zero-voltage switching (2001)

A new primary-switched AC/DC power converter and its modulation are presented. It employs a single- or three-phase transformer, with a matrix converter (primary) and a conventional two-level converter (secondary). This allows galvanic isolation at medium-frequency zero-voltage primary commutation and five line-side voltage levels. Two distinct modulation methods are explained in detail, and it is shown how a combination of these allows optimal operation in terms of efficiency and voltage harmonics. Measured waveforms on a 30-kW prototype confirm the expected performance.

This paper describes the alignment system for Helios, an eight-beam, CO2 laser which is now being used in studies involving compression and heating of deuterium-tritium filled glass spheres, 200 to 300 microns in diameter. These studies are directed towards determining the feasibility of laser-initiated fusion for commercial power generation. The laser system reached design-point output of 10 kilojoules at power in excess of 20 terawatts in June 1978.
Flux-Weakening Control of IPM Motors With Significant Effect of Magnetic Saturation and Stator Resistance (2008)

In this paper, we propose a systematic optimization approach to flux-weakening control of interior permanent-magnet (IPM) motors, which operate in magnetic saturation. The current commands are chosen to be optimal so as to minimize power loss not only in the constant-torque region but also in the constant-power region. Our approach aims at the same objective as the previously known flux-weakening control. Furthermore, the motor torque of an IPM motor in magnetic saturation can be made exactly linear with respect to the torque command. Thereby, our systematic approach can provide not only maximal power efficiency but also torque linearity. In doing so, we consider a more general situation than that considered in prior literature. Specifically speaking, the physical constraints in stator currents and voltages, and the effect of stator resistance are all taken into full account. As a result, the optimization problem becomes very complicated. Nonetheless, we have successfully found the approximate optimal solution, which can be readily implemented on a usual high-speed microprocessor. The practical effectiveness of the proposed control method is also demonstrated through various simulation and experimental results.
