PROPOSAL OF LIFE CYCLE DESIGN SUPPORT METHOD USING DISPOSAL CAUSE ANALYSIS MATRIX (2003)

This paper proposes a decision support method for determining life cycle scenarios in environmentally conscious product design. Here, decision of life cycle scenarios includes decision of objectives of design modification and selection of appropriate life cycle options, such as upgrading, remanufacturing, maintenance, and reuse. Since main objectives of this research include offering a simple and convenient tool to designers, quality function deployment is employed. The basic idea of this methodology is to analyze main disposal causes of a product by using “disposal cause analysis matrix,” which is proposed here, and to modify design of the product so as to reduce analyzed disposal causes. This will results in extension of product life and long-term usage of components. The method consists of four steps; namely, analysis of disposal causes of a product, selection of life cycle options and components to be replaced and reused, modularization of the product, and determination of life cycle scenarios. This paper also illustrates result of a case study using a cellular phone in order to show how the proposed method supports the decision process of life cycle scenarios.
Novel Pre Distortion for Mach-Zendher Modulator Based on Symmetric Imbalance (2017)

A new approach for MZM predistortion is proposed. The method replaces the push-pull configuration with an imbalance which compensates overall impairments and can be applied for improving manufacturing variances regardless of distortion mechanism.
A test sequence generation method for communication protocols using the SAT algorithm (2003)

Abstract The specification for a communication protocol is generally represented by a finite‐state machine, and the operation of the machine is represented by transitions among states. The device implementing such specification is called the implementation under test (IUT). It is important for the IUT that its operation should be verified for all state transitions on the finite‐state machine given in the specification. This test is called the conformance testing. In such testing it is important to generate efficiently a route containing all state transitions from the initial state. This problem is called the test sequence generation problem. This paper considers the test sequence generation problem for a communication protocol and proposes an application of an algorithm for satisfiability problem (SAT) that can flexibly handle various constraints, such as the order constraint and the time constraint among multiple constraints. The proposed method is applied to the dynamic host configuration protocol (DHCP) and its effectiveness is demonstrated. © 2003 Wiley Periodicals, Inc.

Holographic Doppler Imaging of Rotating Objects (1975)

The Doppler frequency shift of coherent light reflected from rotating objects is used to obtain one-dimensional resolution much greater than the classical limit for aperture limited imaging systems. The Doppler information is processed by using the temporal and spatial filtering properties of modulated-referencewave holograms. The holographic reconstruction is a superresolved image. Resolution improvements greater than 200 times the classical limit were obtained at good signal-to-noise ratios.
GC headspace analysis of intermediates in the sol-gel synthesis of magnesium silicates (1992)

The first stage reactions associated with the sol-gel synthesis of amorphous precursors for magnesium silicates such as forsterite and enstatite were examined. Gas chromatographic (GC) analysis of the headspace of a mixture of Mg(OMe)2 and Si(OEt)4 in methanol revealed that transesterification had occurred to form Si(OMe)4, as the major product, and Si(OMe)3(OEt); a Mg:Si molar ratio as low as 0.03 in a 0.2M solution would cause this exchange within 3.5 h. Mg(OMe)2 induced catalytic alkoxide exchange in the mixed alcohol alkoxide solutions of TMOS in ethanol and TBOS in methanol as well. A minimum of 0.0012 mol Mg(OMe)2 per mol TEOS was needed to form the exchange series of TEOS, Si(OMe)(OEt)3, Si(OMe)2(OEt)2, Si(OMe)3(OEt), and TMOS within 1.5 h. The exchange was an equilibrium reaction that depended on solvent composition, and favored methoxy substitution. Other compounds found to catalyze the transesterification of the TEOS in methanol were NaOMe, LiOMe, Ca(OMe)2, HCl, and NH4OH; the alkoxides were the most effective.
Automatic breath phase detection using only tracheal sounds (2010)

While automatic distinction between the two breath phases (inspiration/expiration) can be done easily using lung sounds' intensity, it is challenging to do the same using only tracheal breath sounds. The current acoustic flow estimation methods use tracheal breath sounds to estimate the amount of flow and the onset of breath but also use lung sounds for respiratory phase identification. It would be advantageous to have an automatic and accurate method to identify breath phases from the tracheal signal. One may argue that given the alternation of respiratory phases, breath phase identification from tracheal sounds would be an easy task if one knows the first phase. However, during breathing, an event such as apnea, swallowing, or coughing may change the alternating nature of breath phases. In this study we have investigated several parameters derived from the phase duration, the shape of the sound envelope within each phase, and the sound's intensity in each phase, to develop a reliable method to differentiate between the two respiratory phases using only tracheal breath sounds. We used data from 6 healthy individuals, without any history of pulmonary diseases at 4 different flow levels (shallow, tidal, medium and very high). The most prominent features were found to be those derived from the duration, area and shape of the sound envelope in each phase. With a voting equation using the three most prominent features, our proposed method has shown an accuracy of 93.1% with sensitivity of 93.4% and specificity of 92.8% for breath phase identification without the need for assuming breath phase alteration.
New iridium and rhodium chiral di-N-heterocyclic carbene (NHC) complexes and their application in enantioselective catalysis (2009)

New iridium and rhodium complexes prepared from C2-symmetric trans-9,10-dihydro-9,10-ethanoanthracene-11,12-bis(1-R)-benzimidazolidine-2-ylidene ligands (R=Me, iPr, and diPh) have been synthesized and characterized. Their catalytic activities have been tested in enantioselective hydrogenation and hydroformylation reactions. The ee's for the reactions are low. Evidence indicates that even chelating di-N-heterocyclic carbene ligands are susceptible to reductive elimination.
High-resolution adaptive optics scanning laser ophthalmoscope with dual-deformable mirrors for large aberration correction (2007)

Scanning laser ophthalmoscopes with adaptive optics (AOSLO) have been shown previously to provide a noninvasive, cellular-scale view of the living human retina. However, the clinical utility of these systems has been limited by the available deformable mirror technology. In this paper, we demonstrate that the use of dual deformable mirrors can effectively compensate large aberrations in the human retina, making the AOSLO system a viable, non-invasive, high-resolution imaging tool for clinical diagnostics. We used a bimorph deformable mirror to correct low-order aberrations with relatively large amplitudes. The bimorph mirror is manufactured by Aoptix, Inc. with 37 elements and 18 &mgr;m stroke in a 10 mm aperture. We used a MEMS deformable mirror to correct high-order aberrations with lower amplitudes. The MEMS mirror is manufactured by Boston Micromachine, Inc with 144 elements and 1.5 &mgr;m stroke in a 3 mm aperture. We have achieved near diffraction-limited retina images using the dual deformable mirrors to correct large aberrations up to ±3D of defocus and ±3D of cylindrical aberrations with test subjects. This increases the range of spectacle corrections by the AO systems by a factor of 10, which is crucial for use in the clinical environment. This ability for large phase compensation can eliminate accurate refractive error fitting for the patients, which greatly improves the system ease of use and efficiency in the clinical environment.
Establishment of Vero cell RNA polymerase I-driven reverse genetics for Influenza A virus and its application for pandemic (H1N1) 2009 influenza virus vaccine production (2013)

The constant threat of newly emerging influenza viruses with pandemic potential requires the need for prompt vaccine production. Here, we utilized the Vero cell polymerase I (PolI) promoter, rather than the commonly used human PolI promoter, in an established reverse-genetics system to rescue viable influenza viruses in Vero cells, an approved cell line for human vaccine production. The Vero PolI promoter was more efficient in Vero cells and demonstrated enhanced transcription levels and virus rescue rates commensurate with that of the human RNA PolI promoter in 293T cells. These results appeared to be associated with more efficient generation of A(H1N1)pdm09- and H5N1-derived vaccine seed viruses in Vero cells, whilst the rescue rates in 293T cells were comparable. Our study provides an alternative means for improving vaccine preparation by using a novel reverse-genetics system for generating influenza A viruses.
Highly luminescent phosphine oxide-containing bipolar alkynylgold(<scp>iii</scp>) complexes for solution-processable organic light-emitting devices with small efficiency roll-offs (2018)

We report the synthesis of alkynylgold(iii) complexes with an electron-transporting phosphine oxide moiety in the tridentate ligand and hole-transporting triarylamine moieties as auxiliary ligands to generate a new class of phosphine oxide-containing bipolar gold(iii) complexes for the first time. Such gold(iii) complexes feature high photoluminescence quantum yields of over 70% in 1,3-bis(<i>N</i>-carbazolyl)benzene thin films with relatively short excited-state lifetimes of less than 3.9 μs at a 20 wt% dopant concentration. Highly efficient solution-processable organic light-emitting devices have been prepared with superior current efficiencies of up to 51.6 cd A<sup>-1</sup> and external quantum efficiencies of up to 15.3%. Notably, triplet-triplet annihilation has been significantly reduced, as exemplified by a very small efficiency roll-off of ∼1% at a practical brightness of 500 cd m<sup>-2</sup>.
Freeze-Drying Monitoring Using a New Process Analytical Technology: Toward a “Zero Defect” Process (2013)

This article presents a new process analytical technology to monitor a vial freeze-drying process taking into account the batch nonuniformity. It is based on a soft sensor, using a mathematical model of the process, and on the temperature measurement obtained using a new wireless device. It allows estimating the residual ice content in the monitored vials until the end of the primary drying stage and the values of the heat (and mass transfer) coefficients. Experiments carried out with aqueous solutions containing various excipients (sucrose, mannitol, polyvinylpyrrolidone) or with a pharmaceutical formulations show the effectiveness of the proposed system.
NCN Trianionic Pincer Ligand Precursors: Synthesis of Bimetallic, Chelating Diamide, and Pincer Group IV Complexes (2010)

This report details the synthesis of new NCN trianionic pincer ligand precursors and metalation reactions to form group (IV) complexes. N,N'-[1,3-phenylenebis(methylene)]bis-2,6-diisopropylaniline [2,6-(i)PrNCN]H(3) (8) was converted to the N,N'-substituted Si(IV), Sn(IV), Mg(II), and Zn(II) derivatives. [2,6-(i)PrNCHN](SiMe(3))(2) (9-Si) and [2,6-(i)PrNCHN](SnMe(3))(2) (9-Sn) form by first treating 8 with MeLi followed by Me(3)MCl, where M = Si or Sn. Single crystal X-ray experiments indicate 8, 9-Si, and 9-Sn have similar structural features in the solid state. [2,6-(i)PrNCHN](mu-MgCl.THF)(2) (12) forms by treating 8 with MeMgCl, and its solid state structure revealed a bis-mu-MgCl bridging unit. The (1)H NMR spectrum of 12 reveals a dynamic process occurs in solution. A variable temperature (1)H NMR experiment failed to quench the dynamic process. {[2,6-(i)PrNCHN]Zn}(2) (13) forms upon treating {[2,6-(i)PrNCHN]Li(2)}(2) (10) with anhydrous ZnCl(2) and is a dimer in the solid state. Again, dynamic (1)H NMR behavior is observed, and a mechanism is provided to explain the apparent low symmetry of 13 in solution. Extension of the aliphatic arm of the NCN ligand provides the new N(C)C(C)N pincer ligand precursors N,N'-(2,2'-(1,3-phenylene)bis(ethane-2,1-diyl))bis(3,5-bis(trifluoromethyl)aniline) [3,5-CF(3)N(C)C(C)N]H(3) (16) and [3,5-CF(3)N(C)CH(C)N](SiMe(3))(2) (17). A more rigid ligand architecture was accessed by synthesis of the anthracene derived pincer ligand anthracene-1,8-diylbis(N-3,5-bistrifluormethylaniline) [3,5-CF(3)N(C)C(anth)(C)N]H(3) (18). Treating {Zr(NMe(2))(4)}(2) with 2 equiv of 16 provides the dimer {(mu-3,5-CF(3)N(C)CH(C)N)Zr(NMe(2))(3)NHMe(2)}(2) (19). Treating Hf(NMe(2))(4) with 18 provides the bimetallic complex (mu-3,5-CF(3)N(C)CH(anth)(C)N){Hf(NMe(2))(3)NHMe(2)}(2) (20) in which one ligand bridges two Hf(IV) ions. Salt metathesis between 10 and ZrCl(2)(NMe(2))(2)(THF)(2) provides the mononuclear complex [2,6-(i)PrNCHN]Zr(NMe(2))(2) (21) in which the NCN ligand is bound as a chelating diamide. Thermoysis of 21 does not lead to formation of a trianionic pincer complex. Instead, treating HfCl(4) with {[2,6-(i)PrNCN]Li(3)}(2) (11) followed by MeLi provides the trianionic pincerate complex [2,6-(i)PrNCNHfMe(2)][Li(DME)(2)] (23). In the solid state the Hf ion has distorted trigonal bipyramidal geometry.
Overlay measurement based on dual-overlay grating image (2008)

We develop a novel target, dual-overlay grating, used in the overlay measurement with an optical bright-field imaging tool. The dual-overlay grating is the combination of two overlay gratings with different pitch. The two overlay grating are approached each other and the separation gap between them is sub-micrometer. The image in the proximity of the boundary of two overlay gratings is measured at in-focus position, and a method is built to analyze the image. The gradient value of image and a merit value are calculated. A series of dual-overlay grating is measured and analyzed with different overlay offset. We found the relation between the merit value and overlay offset is linear in certain region, and the dual-overlay grating has the nano-scale resolution to the overlay offset. Thus, the dual-overlay grating has potential application in overlay metrology for the process control in the future semi-conductor manufacturing.

<title>Imaged Document Optical Correlation and Conversion System (IDOCCS)</title> (1999)

Today, the paper document is fast becoming a thing of the past. With the rapid development of fast, inexpensive computing and storage devices, many government and private organizations are archiving their documents in electronic form (e.g., personnel records, medical records, patents, etc.). In addition, many organizations are converting their paper archives to electronic images, which are stored in a computer database. Because of this, there is a need to efficiently organize this data into comprehensive and accessible information resources. The Imaged Document Optical Correlation and Conversion System (IDOCCS) provides a total solution to the problem of managing and retrieving textual and graphic information from imaged document archives. At the heart of IDOCCS, optical correlation technology provides the search and retrieval capability of document images. The IDOCCS can be used to rapidly search for key words or phrases within the imaged document archives and can even determine the types of languages contained within a document. In addition, IDOCCS can automatically compare an input document with the archived database to determine if it is a duplicate, thereby reducing the overall resources required to maintain and access the document database. Embedded graphics on imaged pages can also be exploited, e.g., imaged documents containing an agency's seal or logo, or documents with a particular individual's signature block, can be singled out. With this dual capability, IDOCCS outperforms systems that rely on optical character recognition as a basis for indexing and storing only the textual content of documents for later retrieval.
Sutureless repair of corneal injuries using naturally derived bioadhesive hydrogels (2019)

Corneal injuries are common causes of visual impairment worldwide. Accordingly, there is an unmet need for transparent biomaterials that have high adhesion, cohesion, and regenerative properties. Herein, we engineer a highly biocompatible and transparent bioadhesive for corneal reconstruction using a visible light cross-linkable, naturally derived polymer, GelCORE (gel for corneal regeneration). The physical properties of GelCORE could be finely tuned by changing prepolymer concentration and photocrosslinking time. GelCORE revealed higher tissue adhesion compared to commercial adhesives. Furthermore, in situ photopolymerization of GelCORE facilitated easy delivery to the cornea, allowing for bioadhesive curing precisely according to the required geometry of the defect. In vivo experiments, using a rabbit stromal defect model, showed that bioadhesive could effectively seal corneal defects and induce stromal regeneration and re-epithelialization. Overall, GelCORE has many advantages including low cost and ease of production and use. This makes GelCORE a promising bioadhesive for corneal repair.
Optimum Spatio-Spectral Filtering Network for Brain–Computer Interface (2010)

This paper proposes a feature extraction method for motor imagery brain-computer interface (BCI) using electroencephalogram. We consider the primary neurophysiologic phenomenon of motor imagery, termed event-related desynchronization, and formulate the learning task for feature extraction as maximizing the mutual information between the spatio-spectral filtering parameters and the class labels. After introducing a nonparametric estimate of mutual information, a gradient-based learning algorithm is devised to efficiently optimize the spatial filters in conjunction with a band-pass filter. The proposed method is compared with two existing methods on real data: a BCI Competition IV dataset as well as our data collected from seven human subjects. The results indicate the superior performance of the method for motor imagery classification, as it produced higher classification accuracy with statistical significance ( ≥ 95% confidence level) in most cases.
Detection of Protein-Protein Interactions in Live Cells and Animals with Split Firefly Luciferase Protein Fragment Complementation (2008)

Protein fragment complementation has emerged as a powerful tool for measuring protein-protein interactions in the context of live cells. The adaptation of this strategy for use with firefly luciferase now allows for the non-invasive, quantitative, real-time readout of protein interactions in lysates, live cells, and whole animals. Bioluminescence provides a robust imaging modality due to its extremely low background signal and large dynamic range. The split luciferase fusion constructs described here are inducible by addition of ligands, small molecules or drugs, in this example, rapamycin, and have been shown to work in vivo.
Coexistence of Memristance and Negative Differential Resistance in a Nanoscale Metal‐Oxide‐Metal System (2011)

We experimentally demonstrate and present an analytical model for a nanoscale metal/oxide/metal device that simultaneously exhibits memristance, based on oxygen vacancy drift, and current-controlled negative differential resistance, based on a metal-insulator transition instability. We show that this oxide nanodevice can be used to fabricate a continuously tunable voltage-controlled oscillator.
Lessons Learned on the Application of Vibration Absorbers for Enhanced Cannon Stabilization (2001)

This paper will summarize the successful application of muzzle‐end vibration absorbers to reduce cannon vibration. This technology constitutes a weapons stabilization approach that focuses on passive mechanical structural modification of the cannon, rather than relying upon an external control law to actively cancel vibrations. Challenges encountered during field testing, non‐ideal behavior, and performance evaluation using digital signal processing will be highlighted.
Two distinct families of human and bovine interferon-alpha genes are coordinately expressed and encode functional polypeptides. (1985)

The classical human interferon-alpha (HuIFN-alpha) gene family is estimated to consist of 15 or more nonallelic members which encode proteins sharing greater than 77% amino acid sequence homology. Low-stringency hybridization with a HuIFN-alpha cDNA probe permitted the isolation of two distinct classes of bovine IFN-alpha genes. The first subfamily (class I) is more closely related to the known HuIFN-alpha genes than to the second subfamily (class II) of bovine IFN-alpha genes. Extensive analysis of the human genome has revealed a HuIFN-alpha gene subfamily corresponding to the class II bovine IFN-alpha genes. The class I human and bovine IFN-alpha genes encode mature IFN polypeptides of 165 to 166 amino acids, whereas the class II IFN-alpha genes encode 172 amino acid proteins. Expression in Escherichia coli of members of both gene subfamilies results in polypeptides having potent antiviral activity. In contrast to previous studies which found no evidence of class II IFN-alpha protein or mRNA expression, we demonstrate that the class I and class II IFN-alpha genes are coordinately induced in response to viral infection.

CRYSTALLINE <font>SrTiO</font><sub>3</sub> THIN FILMS ON SILICON BY PULSED LASER DEPOSITION (2005)

We have developed a process to grow SrTiO 3 ( STO ) thin films showing single (110) orientation directly on Si by means of pulsed laser deposition technique. The growth of STO films directly on Si has been described. The crystallinity of the grown STO films was characterized by X-ray diffraction analysis of θ-2θ scan and rocking curve. Our results may be of interest for better understanding of the growth based on the perovskite oxide thin films on silicon materials.
