NUMERICAL SIMULATION OF FULL VEHICLE DYNAMIC BEHAVIOUR BASED ON THE INTERACTION BETWEEN ABAQUS/STANDARD AND EXPLICIT CODES (2003)

Abstract: This work describes a numerical methodology based on the finite element method used for the transient dynamic simulation of the full vehicle rolling on different kind of obstacles. Some issues related to the tire finite element model development and its validation, by numerical-experimental comparison, have been discussed. The strategy to combine the static simulations such as the tire inflating, the vehicle weight application and suspension pre loading, with transient dynamic analysis of the car rolling over the obstacle has been chosen. The methodology, based on integration of Abaqus Implicit and Explicit codes, has been successfully applied for the dynamic simulation of Fiat Punto car passing over comfort and pothole obstacle. 1.
A bias circuit based on resistorless bandgap reference in 0.35-&amp;amp;#956;m SOI CMOS (2006)

A bias circuit based on resistorless bandgap reference is designed and fabricated in 0.35-/spl mu/m silicon-on-insulator (SOI) CMOS. The reference voltage generated by the bandgap core which is arranged to give zero temperature coefficient (ZTC) around room temperature is buffered across a resistor to yield a constant current. This constant current is then mirrored to rationed resistors to give desired constant output voltage levels. The reference voltage is generated using inverse function technique which does not require the use of resistors in the bandgap core. Experimental results demonstrate that the largest bias voltage (1.766 V) has shown only 5 mV variation over the temperature range (20 /spl deg/C to 125 /spl deg/C).

FEA image sensor with electron-beam focusing system (2004)

A 256/spl times/192 pixel FEA image sensor with an electron-beam focusing system was fabricated and tested. The experimental results revealed that the sensor could obtain sufficient resolution for its pixel size of 50/spl times/50 /spl mu/m by focusing the electron beam emitted from the FEA onto a photoconductive target, demonstrating its potential as a practical image sensor with small pixels.
A circular microphone array beamformer based on spherical harmonics (2016)

A circular microphone array that can easily steer its beampattern(s) to any angle in the horizontal plane around the array would be an attractive microphone array for room audio conferencing. An elegant solution to this problem to design a modal beamformer based on circular harmonics. However, a modal beamformer based on circular harmonics suffers from the loss of control of the beampattern out of the plane of the array. We will present a modified modal beamformer for the circular array that is based on spherical harmonics. This approach allows full control of the beampattern and maintains the efficient steerability known from modal beamformers. Measurements of a specific implementation with 16 sensors will be presented.
Treatment of urethral strictures with the KTP 532 laser (1997)

The objective of this study was to evaluate and compare the safety and efficacy of the KTP 532 laser to direct vision internal urethrotomy (DVIU) in the management of urethral strictures. A total of 32 patients were randomized prospectively in this study, 14 DVIU and 18 KTP 532 laser. Patients were evaluated postoperatively with flowmetry and in the case of recurrence with cystourethrography at 3, 12, 24 weeks. With the KTP 532 laser complete symptomatic and urodynamic success was achieved in 15 (83%) patients at 12 and 24 weeks. Success rate was lower in the DVIU group with 9 (64%) patients at 12 weeks and 8 (57%) patients at 24 weeks. With the KTP mean preoperative peak-flow was improved from 6 cc/s to 20 cc/s at 3, 12 and 24 weeks. With DVIU mean preoperative peak-flow was improved from 5.5 cc/s to 20 cc/s at 3 weeks followed by a steady decrease to 13 cc/s at 12 weeks and to 12 cc/s 24 weeks. No complications were observed in either group of patients. Our results confirm that stricture vaporization with the KTP 532 laser is a safe and efficient procedure. It thus represents a valuable alternative in the endoscopic treatment of urethral strictures.
Class II major histocompatibility complex‐restricted T cell function in CD4‐deficient mice (1994)

Previously, we and others have demonstrated that CD4-deficient mice have a normal number of T cells and B cells with a significant population of CD4-8-TcR alpha beta+ T cells. Surprisingly, however, these mice lacking CD4 show in vivo immunoglobulin isotype class switching from IgM to IgG in response to sheep erythrocytes and vesicular stomatitis virus. In this study we have depleted various subpopulations of T cells in vivo and shown that the population of CD4-8-TcR alpha beta+ T cells is responsible for providing "help" in the antibody response of CD4-deficient mice to vesicular stomatitis virus infection. We have used antigen-specific proliferation assays and blocking studies with class I and II major histocompatibility complex (MHC)-specific purified antibodies to show that these cells are class II MHC-restricted in responses against the T cell-dependent antigen keyhole limpet hemocyanin (KLH). Finally, phenotypic analysis of the CD4-CD8- thymocytes in CD4-deficient mice shows that these cells have a more mature phenotype than the CD4-8- thymocytes in wild type mice. These results indicate that CD4 is not absolutely necessary for positive selection or effector function of class II MHC-restricted helper T cells.
Depletion of Glutathione during Bovine Oocyte Maturation Reversibly Blocks the Decondensation of the Male Pronucleus and Pronuclear Apposition during Fertilization1 (1997)

Oocyte-produced glutathione (the tripeptide gamma-glutamyl-cysteinyl-glycine; GSH) has been implicated in the reduction of disulfide bonds in the sperm nucleus during fertilization and thus in the development of the male pronucleus (PN). In this study, we show that the depletion of endogenous glutathione by 10 mM buthionine sulfoximine (BSO; specific inhibitor of GSH synthesis) during bovine oocyte maturation (24 h in vitro; represents prophase I to metaphase II transition in this species) blocks the formation of a male PN in > 85% of treated oocytes (vs. 6.8% in controls) and prevents the assembly of the sperm aster microtubules in approximately 35%. Consequently, the pronuclear migration and apposition do not occur. Ultrastructural observations suggest that the effect of BSO on pronuclear apposition might be due to incomplete disassembly of the sperm tail connecting piece, which normally leads to the release of the sperm centriole and to the reconstitution of the zygotic centrosome during fertilization. The sperm nucleus decondensation and migration blocks were reversed by the treatment of the GSH-depleted oocytes with 1-10 mM dithiothreitol (a disulfide bond-reducing agent) applied 8 h after insemination: 82% of these oocytes exhibited a normal male PN and pronuclear apposition 20 h after insemination. The pool of glutathione seems to be generated during oocyte maturation since > 80% of oocytes that were matured in the absence of BSO displayed a normal male PN, as apposed to a female PN, when inseminated and cultured in the presence of 10 mM BSO. These data suggest that the reduction of disulfide bonds in the sperm after incorporation is important for the formation of the male PN, as well as for the disassembly of the sperm tail connecting piece and pronuclear apposition. The lack of disulfide-reducing power in the GSH-depleted oocytes can be reversed by treatment with disulfide bond-reducing agents.
Crowdsourcing Similarity Judgments for Agreement Analysis in End-User Elicitation Studies (2018)

End-user elicitation studies are a popular design method, but their data require substantial time and effort to analyze. In this paper, we present Crowdsensus, a crowd-powered tool that enables researchers to efficiently analyze the results of elicitation studies using subjective human judgment and automatic clustering algorithms. In addition to our own analysis, we asked six expert researchers with experience running and analyzing elicitation studies to analyze an end-user elicitation dataset of 10 functions for operating a web-browser, each with 43 voice commands elicited from end-users for a total of 430 voice commands. We used Crowdsensus to gather similarity judgments of these same 430 commands from 410 online crowd workers. The crowd outperformed the experts by arriving at the same results for seven of eight functions and resolving a function where the experts failed to agree. Also, using Crowdsensus was about four times faster than using experts.
A KYP Lemma for LMI Regions (2007)

In this technical note, a Kalman-Yakubovich-Popov (KYP) lemma is discussed for linear matrix inequality (LMI) regions. Sufficient quadratic stability conditions are developed for an uncertain linear system subject to time varying uncertainty satisfying a quadratic inequality. Furthermore, the quadratic stability conditions are shown to guarantee the satisfaction of a frequency domain inequality.

Extended Electrochemical Reliability Study of All-Solid-State Thin Film Microbatteries (2014)

The long-term reliability of all-solid-state thin film microbatteries was studied through a deepened electrical characterization of the solid interfaces. After 1,500 cycles, the cells cycled at 60°C showed few changes of the intrinsic parameters at the interfaces of the active layers from the electrochemical stack. Through the implementation of an extended experimental approach incorporating impedance spectroscopy measurements from 1 MHz to 200 mHz, coupled to an equivalent electrical model, charge transfer resistances and exchange currents densities were extracted. The study highlights the reliability performances of the EnFilm™ HiCap microbattery technology. The results were confirmed through the experimental behavior study, the electrochemical integrity of EnFilm™ HiCap technology is preserved in use. Devoid of Solid Electrolyte Interface (SEI) typical of conventional liquid electrolyte Li-ion systems, all-solid-state microbatteries therefore present physical characteristics of good reliability performances.
Astrobiological Polarimeter (2008)

Chirality is an excellent indicator of life, but naturally occurring astrobiological (as well as terrestrial) samples nearly always exhibit massive depolarizing light scattering, which renders conventional polarimeters useless. For astrobiological applications, we instead consider a novel polarimeter originally developed for non-invasive human-glucose measurement. It involves deliberately rotating in time the plane of polarization of a linearly polarized beam and detecting the shift in the plane of the rotating linearly polarized component of the transmitted light from a chiral sample relative to the input polarization plane. We find that this polarimeter can operate in 3 orders of magnitude more depolarizing scattering than conventional polarimeters. Furthermore, it can also be designed to be lightweight, compact, and energy efficient.
A novel technology for a-Si TFT-LCD's with buried ITO electrode structure (1994)

A novel process technology for a-Si TFT-LCD's with the buried ITO electrode (BI) structure was developed and applied to 10-in-diagonal LCD panels. By employing the BI structure, an aperture ratio of 29% was achieved in high resolution panels with a pixel size of 192 /spl mu/ and the pixel defect density was reduced to about one third of the conventional structure. The defect reduction effect of the BI structure was also confirmed theoretically. The BI structure provides significant advantages for high-performance TFT-LCD's.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">&gt;</ETX>
Dosimetry of solid tumors (1993)

Dosimetry data arising from a decade of radioimmunotherapy are summarized along with techniques utilized to arrive at the reported dose estimates. Generality of the MIRD methodology allows it to serve as a vehicle for the calculation of solid tumor dosimetry although several limitations exist. Nonstandard geometries of solid tumors will ultimately necessitate determination of absorbed fractions for the individual tumors. Several approaches currently under investigation are described. For reasons of practicality, solid tumor dosimetry estimates continue to use the assumption of homogeneous activity distribution in a source organ, accounting for either all radiation or only nonpenetrating radiation. As computation tools become available for incorporating inhomogeneous cellular level data, the currently used “average dose” as an index of tumor sterilization will likely be replaced with a statistical distribution based on the number of viable cells in the tumor volume. Estimates of a tumor control dose would be based upon a linear extension of dose coupled with a threshold dose for cell sterilization.
Optical Fiber Sensors: Working Principle, Applications, and Limitations (2022)

Fiber‐optic technology emerged originally for applications in data transmission and telecommunications. However, sensors based on fiber‐optics have been developed rapidly because of their excellent sensing performances and capability to function in remote and harsh environments. The usage of fiber‐optic sensors has flourished in many fields over the past 30 years due to the fiber‐optic's inherent advantages: cost‐effectiveness, miniaturized size, light weight, and immunity to electromagnetic interference. This work reviews the fiber‐optic sensors based on Bragg gratings, long period gratings, interferometers, surface plasmon resonance, fluorescence, and light diffusion. Brief theory of sensing principle, fabrication method, applications, advantages and disadvantages of the different fiber‐optic sensors, are addressed. Recent progress in numerous sensing fields, including environmental, industrial, and biomedical are discussed for each class of fiber‐optic sensors. The review highlights the methods and techniques used to overcome the sensing challenges. Finally, prospect of future developments of fiber‐optic sensors is summarized.

Iridium Models of Rhodium Intermediates in Hydroformylation Catalysis: Isolation and Molecular Structures of Fluxional ae and ee Isomers (2014)

We report the synthesis and single-crystal molecular structures of two stereoisomers of trigonal-bipyramidal hydrido dicarbonyl Ir complexes [(L2)Ir(H)(CO)2] with ae (axial–equatorial) and ee (equatorial–equatorial) ligand P coordination and fluxional behavior in solution. L2 is a new chelating bisphosphite with unprecedented high selectivity in Rh-catalyzed bis-hydroformylation of butadiene to adipic aldehyde. These Ir analogues are ideal stabilized structural models for nonseparable ae and ee Rh-hydroformylation resting state isomers [(L2)Rh(H)(CO)2]. With Ir, both stereoisomers with the same ligand could be characterized independently for the first time.
A multi-phase shared bus structure for the fast Fourier transform (2002)

The multi-phase shared bus structure is proposed for the implementation of the complex data flows in fast Fourier transforms (FFTs). With multiphase techniques, the executions of the pipelines are time-skewed. Data communications between pipeline stages can be multiplexed via the shared bus. The routing area is small and independent of the routing complexity. For the 8-point butterfly at 100 MHz data rate, multi-phase implementation needs only 30% area compared to direct routing. By proper phase assignment, the processing latency can also be reduced. The latency of the 8-point FFT design example is reduced to 68%. The communication cost of the direct implementation and the proposed structure is estimated and compared.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">&gt;</ETX>

Role of CYP1B1 in Glaucoma (2007)

Glaucoma is a leading cause of blindness, estimated to affect 60 million people by 2010, and represents a heterogeneous group of neurodegenerative disease. The two major types of glaucoma include primary open-angle glaucoma (POAG) and primary congenital glaucoma (PCG). A genetically heterogeneous group of developmental disorders known as anterior segment dysgenesis (ASD) have been reported to be associated with increased intraocular pressure (IOP) and glaucoma. These include Peters' anomaly, Rieger's anomaly, aniridia, iris hypoplasia, and iridogoniodysgenesis. Genetic linkage analysis and mutation studies have identified CYP1B1 as a causative gene in PCG, as a modifier gene in POAG, and, on rare occasions, as causative gene in POAG as well as in several ASD disorders. CYP1B1-deficient mice exhibit abnormalities in their ocular drainage structure and trabecular meshwork that are similar to those reported in human PCG patients. Accordingly, it is speculated that diminished or absent metabolism of key endogenous CYP1B1 substrates adversely affects the development of the trabecular meshwork. CYP1B1 protein is involved in the metabolism of steroids, retinol and retinal, arachidonate, and melatonin. The conserved expression of CYP1B1 in both murine and human eyes, its higher expression in fetal than adult eyes, and its biochemical properties are consistent with this hypothesis. The exact role of CYP1B1 in the pathogenesis of glaucoma and other ASD disorders remains to be elucidated.
Enhancement of polygalacturonase production from enterobacter aerogenes NBO2 by submerged fermentation (2013)

The bacterium, Enterobacter aerogenes NBO2 was cultivated in 250 ml Erlenmeyer flask under submerged fermentation and physiochemical characteristics were studied in order to improve the pectinase production. Fermentation condition improved were pH 6.5, cultivation temperature of 37°C, inoculums size of 3% (v/v) 7.4x10 8 cell/ml and agitation speed of 250 rpm, together with pectin concentration of 1.50% (w/v) and 0.26% of yeast extract as carbon and nitrogen sources, respectively had produced the highest pectinase production of about 18.54 U/mL and 0.43 g/L cell growth at 24 hours incubation time. The enzyme production by this bacterial isolate was found not growth dependent. There were increment in enzyme production and cell growth after improvement of physical and chemical parameters.
Facile Synthesis of a Furan–Arylamine Hole‐Transporting Material for High‐Efficiency, Mesoscopic Perovskite Solar Cells (2015)

A novel hole-transporting molecule (F101) based on a furan core has been synthesized by means of a short, high-yielding route. When used as the hole-transporting material (HTM) in mesoporous methylammonium lead halide perovskite solar cells (PSCs) it produced better device performance than the current state-of-the-art HTM 2,2',7,7'-tetrakis-(N,N-di-p-methoxyphenylamine)-9,9'-spirobifluorene (spiro-OMeTAD). The F101-HTM-based device exhibited both slightly higher Jsc (19.63 vs. 18.41 mA cm(-2) ) and Voc (1.1 vs. 1.05 V) resulting in a marginally higher power conversion efficiency (PCE) (13.1 vs. 13 %). The steady-state and time-resolved photoluminescence show that F101 has significant charge extraction ability. The simple molecular structure, short synthesis route with high yield and better performance in devices makes F101 an excellent candidate for replacing the expensive spiro-OMeTAD as HTM in PSCs.
siRNA screen of the human signaling proteome identifies the PtdIns(3,4,5)P3-mTOR signaling pathway as a primary regulator of transferrin uptake (2007)

Our study identifies the PtdIns(3,4,5)P3-mTOR signaling pathway as a new regulator of iron-transferrin uptake and serves as a proof-of-concept that targeted RNA interference screens of the signaling proteome provide a powerful and unbiased approach to discover or rank signaling pathways that regulate a particular cell function.
Compact imaging system for quantitative fluorescence sensing through autofluorescent, scattering and absorbing media (Conference Presentation) (2018)

Fluorescence sensing through skin using wearable and cost-effective sensors can enable numerous biomedical applications, including continuous monitoring and quantification of biomarkers in conjunction with embedded fluorescent biosensors. Strong autofluorescence of the skin and its varying temporal response to excitation make it challenging to achieve highly sensitive fluorescence sensing at the visible part of the electromagnetic spectrum. Here, we demonstrate a compact, cost-effective and light-weight fluorescence imaging system for quantitative sensing through a highly autofluorescent, scattering and absorbing medium. We built a mobile fluorescence microscope weighing < 40 grams to sensitively quantify the concentration of fluorescent dyes through a skin tissue phantom. The optical characteristics of the skin phantom, such as scattering, absorption, and autofluorescence were designed to closely resemble the characteristics of human skin. In order to separate the target fluorescence emission signal from the tissue phantom’s autofluorescence we utilized an oblique Gaussian excitation profile, and performed our processing in the spatial frequency domain. Using an excitation intensity that is 8-fold below the safe exposure limit determined for human skin, we detected and quantified the concentration of Alexa 647 dye molecules in a microfluidic reservoir (with a volume of 0.01 µl) that is positioned 0.5 mm and 2 mm underneath our skin phantom, and achieved a detection limit of ~106 pg/ml and 5.3 ng/ml, respectively. Our method is also robust to lateral misalignments between the sample and the imaging device, with e.g., ~2-fold loss in limit of detection for ~0.6 mm lateral misalignment.
