Ikaros extended mission and advanced solar power sail mission (2012)

This paper presents IKAROS extended missions. IKAROS entered its extended operation phase at the beginning of 2011. In the extended operation, the spin rate was decreased to observe the deformation of the sail under low centrifugal force environment. On Oct. 18, 2011, IKAROS transferred to the reverse spin to enhance the knowledge about the effect of stiffness of membrane against the solar radiation pressure. We investigated the change of the attitude motion by the reverse spin mission. At the end of 2011, IKAROS moved to hibernation mode because the Sun angle was increased. We searched for IKAROS considering the attitude and orbital motion during hibernation. On Sep. 6, 2012, we succeedcd in tracking IKAROS which came out of hibernation. A solar power sail can be a hybrid propulsion system with a solar sail by activating the ultra-high specific impulse ion engines with the power generated by thin film solar cells. This paper also introduces an advanced solar power sail mission toward Jupiter and Trojan asteroids via hybrid electric photon propulsion.
Limits on echo return loss enhancement on a voice coded speech signal (2003)

Acoustic echo cancellation is a desirable feature for small cellular handsets that have significant acoustic coupling from speaker to microphone. Current echo cancellation techniques prefer an echo canceller to be placed at the wireless handset. Since echo cancellation requires much processing power it is beneficial to move the echo canceller to the base station, where power consumption will not be a constraint. This paper examines the feasibility of performing linear echo cancellation on a signal coming from a mobile at the base station. The mobile signal at the base station contains speech coding which may degrade the effectiveness of echo cancellation. The performance of linear echo cancellation on mobile echo encoded and decoded by low bit rate speech coders operating at 4 kbits/sec to 13 kbits/sec, including GSM full rate, G.723a, G.729, and AMR speech coders, was investigated. The best echo return loss enhancement achieved depends on the bit rate of the coder, and is usually less than 10 dB for the low bit rate operating range examined.
Hierarchical biphilic micro/nanostructures for a new generation phase-change heat sink with 1800 W/cm2 CHF limit (2017)

The physics of membrane-based microchannel boiling process is explained. Through a set of fundamental studies conducted on several membrane-based heat sinks designed with different configurations incorporating surface micro- and nanostructures, the nature of critical heat flux (CHF) limit and its active control is explained. It is commonly known that the occurrence of CHF is accompanied by the formation of significant vapor adjacent to the heated surface such that liquid cannot rewet the surface. In the new approach, flow is constrained within a hydrophilic microstructure by a superhydrophobic vapor-permeable nanofibrous membrane. A bubble bounded between the two structures is pulled away from the hydrophilic heated structure and discharged from the flow, thus leading to rewetting of the heat transfer surface. Hierarchical micro- and nanostructures designed on the heat transfer surface allow to substantially increase the surface wettability. The maximum heat flux removed is approximately 1800 W/cm <sup xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">2</sup> with water used as the test fluid. Only vapor exits the heat sink. Hence, the heat sink exit vapor quality is 100%.
The Stabilizing Effect of a Magnetic Field on the Plasma Production of a Vacuum-Discharge Rotating Plasma Gun (1994)

A coaxial plasma gun which generates a rapidly rotating plasma in a magnetic field has been developed to improve the plasma centrifuge. It is demonstrated that a magnetic field stronger than a critical value is essential to stabilize the high-current vacuum discharge of the plasma gun and to make the plasma production and acceleration reproducible. For example, the critical field is 250G for the discharge current of 13kA and the anode-cathode spacing of 7.5mm. A model is presented in which the critical field is assumed to be determined from the trapping of ionizing electrons in the annular anode-cathode gap. A qualitative agreement is achieved between the model and experiment.
Transparent Thin Film Solid-State Lithium Ion Batteries (2018)

Transparent electrochemical energy storage devices have attracted extensive attention for the power supply of next-generation transparent electronics. In this paper, semitransparent thin film batteries (TFBs) with a grid-structured design have been fabricated on glass substrates using specific photolithography and etching processes to achieve LiCoO<sub>2</sub>/LiPON/Si structures below human eye resolution. UV-vis transmittances up to 60% have been measured for the obtained TFBs. A discharge capacity as high as 0.15 mAh has been recorded upon galvanostatic cycling at the C/2 rate within 4.2-3 V voltage range for the highest transmittances. The capacity variation trend exhibits an initial phase of a gradual decrease with an average capacity loss of 0.15% per cycle and thereafter a second phase with almost stable capacity. Particular attention has been given to the effects of architecture parameters on the TFB optical and electrochemical properties. To the best of our knowledge, this work is the first demonstration of transparent, all inorganic, thin film lithium ion batteries. While reported studies are limited to battery structures involving liquid or polymer materials, our devices will contribute to improve form factor freedom, extend operating ranges, enhance long-term stability, and will be relevant to the integration into various optoelectronic devices.
Synthesis of long-chain coumarines and 2H-chromenes. Spectral and monolayer properties (1979)

Several coumarines and 2H-chromenes containing one or two long-chain substituents were synthesized and their spectroscopic properties (uv, nmr) were investigated. All compounds were studied at the air–water interface. Five of them give a monolayer which is characterized by the pressure–area isotherm. An interpretation of the isotherms is discussed in relation to the molecular structure.

Pasty Polymers in Cancer Drug Therapy (2010)

Abstract Injectable polymeric systems suitable for the localized delivery of anticancer agents are reviewed. These polymeric systems include: drug‐loaded low melting temperature polymers that are injected at the melting temperature of the polymer, usually below 50 °C, that solidify at body temperature to form an in situ device; polymer solutions in buffer or in N‐methyl pyrrolidone, ethanol, or acetate esters which, upon injection in tissue,are absorbed into the tissue and cause precipitation of the polymer at the injection site; in situ crosslinking of polymer solutions to form a polymeric implant; and thermoresponsive polymer solutions that are soluble at room temperature and solidify at body temperature. However, these systems are hydrophilic and suffer from burst release of drug within a few hours post injection. Hydrophobic injectable, pasty, fat‐based polymers that gel when injected in tissue have been used for the extended release of paclitaxel, cisplatin, and other agents. This polymer releases the drug in a controlled manner with no burst release. These systems have a potential use as drug carriers for regional or systemic drug delivery.
Method Using Bilinear Transformation for Measurement of Impedance Parameters of a Multielement Two-Terminal Network (2008)

This paper presents a method for the identification of the impedance parameters of objects, which can be modeled by two-terminal networks. The method uses the properties of bilinear transformation, which allows presentation of object impedance as a function of each parameter of the equivalent circuit of the object. Inverse bilinear transformation allows the determination of the value of each parameter on the basis of impedance measurement at a single frequency. The measurement frequency is selected for each identified element (on the basis of the minimal relative sensitivity of the identified element to changes of other elements), so the number of measurement frequencies is equal to the number of elements to be identified. This makes it possible to shorten the identification time when compared with the traditional identification method based on the impedance spectrum fitting method (complex nonlinear least squares). When the object model and the order of component values are known, the developed method fully assures conditions that allow an implementation in low-cost portable diagnostic instruments.
Evaluation of route diversity performances in millimeter-wave BFWA mesh networks by correlated multivariate gamma distributions (2004)

Broadband fixed wireless access (BFWA) systems have been considered as a promising approach for high-speed access networks. BFWA networks operating at millimeter-wave bands are appropriate for high-density deployment of a high capacity wireless access infrastructure, while there is inherent degradation of radio links due to rain attenuation, especially in tropical or subtropical regions. The authors have proposed a new system architecture of mesh wireless networks (Kishi, Y. et al., Proc. IEEE WCON2001, p.17-20, 2001) whose advantages include route diversity. This paper evaluates the diversity effect under the assumption that the rain attenuation of radio links can be approximated by gamma distributions. By using correlated multivariate gamma distributions, the diversity effect is quantitatively confirmed.
Algebraic lattice constellations: bounds on performance (2005)

In this work, we give a bound on performance of any full-diversity lattice constellation constructed from algebraic number fields. We show that most of the already available constructions are almost optimal in the sense that any further improvement of the minimum product distance would lead to a negligible coding gain. Furthermore, we discuss constructions, minimum product distance, and bounds for full-diversity complex rotated Z[i]/sup n/-lattices for any dimension n, which avoid the need of component interleaving.
Digital PSK to BiO-L demodulator for 2 sup nx(bit rate) carrier (1979)

A phase shift key (PSK) to BiO-L demodulator which uses standard digital integrated circuits is discussed. The demodulator produces NRZ-L, bit clock, and BiO-L outputs from digital PSK input signals for which the carrier is a 2 to the Nth multiple of the bit rate. Various bit and carrier rates which are accommodated by changing various component values within the demodulator are described. The use of the unit for sinusoidal inputs as well as digital inputs is discussed.

Synthesis and analysis of novel polymers with potential for providing both high permselectivity and permeability in gas separation applications (1989)

During the first eight months of project support under our renewal proposal, we have achieved the following important experimental, analytical and publication objectives consistent with our project goal to develop advanced materials for gas separation membrane applications. Synthesized and characterized additional polycarbonate materials beyond those specified in our original proposal to test ideas developed in the course of the work with the originally proposed polycarbonate materials. Completed synthesis and characterization of the originally-proposed polysulfones in our renewal proposal. Also synthesized and begun characterization of additional polysulfone materials beyond those proposed in the renewal proposal to test ideas developed in the course of the work with the originally proposed materials. Began work to synthesize the systematic family of polyesters described in our renewal proposal. Three new papers have appeared in print and we have prepared 4 new manuscripts and given 5 presentations at technical meetings. This brings the total to 11 publications produced under our three-and-a-half years of DOE support.
Pulsed, tunable, single-frequency OP-GaAs OPO for the standoff detection of hazardous chemicals in the longwave infrared (2015)

We present our results on the first nanosecond single-frequency optical parametric oscillator (OPO) emitting in the longwave infrared. It is based on orientation-patterned GaAs (OP-GaAs), and can be pumped by a pulsed singlefrequency Tm:YAP microlaser thanks to its low oscillation threshold of 10 &mu;J. Stable single-longitudinal mode emission of the OPO is obtained owing to Vernier spectral filtering provided by its nested cavity OPO (NesCOPO) scheme. Crystal temperature tuning covers the 10.3-10.9 &mu;m range with a single quasi-phase-matching period of 72.6 &mu;m. Shortrange standoff detection of ammonia vapor around 10.4 &mu;m is performed with this source. We believe that this achievement paves the way to differential absorption lidars in the LWIR with increased robustness and reduced footprint.
Correlation between absolute configuration of benzylic chiral centre and sign of spontaneous polarization of chiral dopants for ferroelectric liquid crystals (1991)

The absolute configuration of a polar-group-substituted benzylic chiral carbon of a chiral dopant for ferroelectric liquid crystals is found to be predictable by the sign of spontaneous polarization of the ferroelectric liquidcrystalline mixtures containing the chiral dopant.
Regulation of podosomes by intracellular pH in avian osteoclasts. (1989)

The effects of changes in intracellular pH (pH1) on the organization of the clear zone of isolated avian osteoclasts in culture were studied. The distribution of podosomes, the close contact areas that mediate the adhesion of osteoclasts to the substrate, was investigated by decoration of microfilaments with fluorescent phalloidin. Intracellular acidification by butyric acid induces significant increase of podosome formation at the level of the clear zone compared to controls. Conversely, alkalinization by HCO3- reduces the percentage of osteoclasts with podosomes. A role of pH1 on the adhesion of the osteoclasts to the substrate is hypothesized.

Demonstration of the heterozygous state for I-cell disease and pseudo-Hurler polydystrophy by assay of N-acetylglucosaminylphosphotransferase in white blood cells and fibroblasts. (1982)

The biochemical abnormalities of I-cell disease (mucolipidosis II) and pseudo-Hurler polydystrophy (mucolipidosis III) can be explained by a deficiency of the enzyme UDP-N-acetylglucosamine:lysosomal enzyme N-acetylglucosamine-1-phosphotransferase. We demonstrate here that obligate heterozygotes for these autosomal recessive diseases have intermediate levels of this enzymatic activity in homogenates of peripheral blood white cells and in extracts from cultured fibroblasts. This finding provides further evidence that the enzyme deficiency is the primary genetic defect in these diseases. In addition, the previous observation that obligate heterozygotes for mucolipidosis III have elevations of total serum beta-hexosaminidase outside the range of normal was confirmed. In studies of three pedigrees of patients with mucolipidosis III, these techniques were used to score individuals at risk for the carrier state.

On the Evolution of an Industrial Software Engineering Graduate Program (2009)

Abstract- Software is the key enabling factor for many industrial giants in product development and the ability to deliver reliable software intensive systems in a cost-efficient manner is becoming the differentiating factor for their future competitiveness. This underlines the importance of an industrially relevant software engineering program and realization of the above fact has lead us to conceptualize a novel graduate program in this domain. The program originated from a set of mutually beneficial motivating factors, which were realized during close collaborations between industry and academia in a global setting. In this paper 1 we present the stakeholder perspectives as well as our experiences during the development and running of such a program.
Single Ribosomal Protein Mutations in Antibiotic-Resistant Bacteria Analyzed by Mass Spectrometry (2001)

Mutations in several ribosomal proteins are known to be related to antibiotic resistance. For several strains of Escherichia coli, the mutated protein is known but the amino acid actually altered has not been documented. Characterization of these determinants for antibiotic resistance in proteins will further the understanding of the precise mechanism of the antibiotic action as well as provide markers for resistance. Mass spectrometry can be used as a valuable tool to rapidly locate and characterize mutant proteins by using a small amount of material. We have used electrospray and matrix-assisted laser desorption ionization-time of flight (MALDI-TOF) mass spectrometry to map out all 56 ribosomal proteins in E. coli based on intact molecular masses. We used this fingerprinting approach to locate variants of ribosomal proteins displaying a change in mass. In particular we have studied proteins responsible for streptomycin, erythromycin, and spectinomycin resistance in three strains of E. coli, and then we characterized each mutation responsible for resistance by analyzing tryptic peptides of these proteins by using MALDI-TOF and nanoelectrospray tandem mass spectrometry. The results provided markers for antibiotic resistance and demonstrated that mass spectrometry can be used to rapidly investigate changes in individual proteins from a complex with picomole amounts of protein.

The Effect of Stress on the Redistribution of Implanted Impurities in GaAs (1983)

The stress introduced by the difference in thermal expansion coefficients between an encapsulant and a substrate was found to affect the redistribution of implanted impurities during annealing. Compressive stress introduced by an film on enhanced the diffusion of implanted Si, Se, and S. Diffusion constants of Si and Se increased exponentially with the increase in the film thickness in a thickness region less than 0.1 μm. The diffusion mechanism was discussed and it was concluded that the change in the jump frequency of diffusing atoms was dominant in determining the effect of stress in the damaged implantation layer. Excess of carriers was also observed in Se‐ and S‐implanted samples, while deficit in carriers was observed in Si‐implanted samples when the samples were subsequently annealed with an film.
A Robust Incubator to Improve Access to Microbiological Culture in Low Resource Environments (2018)

To help address the limitations of operating conventional microbiological culture incubators in low resource environments, a new incubator design was developed and tested to meet the requirements of operation in laboratories without reliable power (power outages up to 12 contiguous hours) or climate control (ambient indoor temperatures from 5 °C to 45 °C). The device is designed to enable adherence to incubation temperatures recommended for growth detection, identification, and drug susceptibility testing (DST) of human pathogenic bacteria. During power outages, stable temperatures are maintained in the device's internal sample compartment by employing phase change material (PCM) as a bi-directional thermal battery to maintain incubation temperature. Five prototypes were tested in a laboratory setting using environmental test chambers and programmable power supplies, and three were field tested in the Lao PDR in situations of intended use. The prototypes successfully held their temperature to within ±1 °C in both laboratory environmental chamber testing as well as during the field test. The results indicate that the device will maintain stable culture temperatures across periods of intermittent power supply, while enabling normal workflow of this could greatly increase the availability of microbiological culture for diagnosis and antimicrobial resistance (AMR) monitoring.
