Growth of Carbon Nanofibers Using Resol-Type Phenolic Resin and Cobalt(II) Catalyst (2013)

This study investigated carbon nanofibers (CNFs) grown on reticulated vitreous carbon (RVC) foam through catalytic deposition of ethylene. Before growing the CNFs, Co(II) on the RVC foam was expected to act as a catalyst by deposition. The preparation of the CNFs was a two-step process. The first step was preparing the RVC from polyurethane (PU) foam. Changes in weight over time were evaluated using two kinds of resol. The change in the mass and state of the sample with the change in temperature was studied during the carbonization process. The second step was to prepare the CNFs. An OH group was attached by the oxidation of the RVC foam. A change in the shape and mass of the sample was observed due to a change in nitric acid concentration and oxidation time. Then, cobalt was deposited to grow CNFs on the RVC foam. Hydrolysis helped to deposit the Co(ll) on the RVC foam. The appropriate time and temperature were investigated for the reduction process. In the last step, CNFs were prepared by the introducing ethylene gas. The resulting samples were analyzed using scanning electron microscopy, energy dispersive spectroscopy, N2-sorption, and X-ray photoelectron spectroscopy.

Highly efficient genome editing for single-base substitutions using optimized ssODNs with Cas9-RNPs (2019)

Target-specific genome editing using engineered nucleases has become widespread in various fields. Long gene knock-in and single-base substitutions can be performed by homologous recombination (HR), but the efficiency is usually very low. To improve the efficiency of knock-in with single-stranded oligo DNA nucleotides (ssODNs), we have investigated optimal design of ssODNs in terms of the blocking mutation, orientation, size, and length of homology arms to explore the optimal parameters of ssODN design using reporter systems for the detection of single-base substitutions. We have also investigated the difference in knock-in efficiency among the delivery forms and methods of Cas9 and sgRNA. The knock-in efficiencies for optimized ssODNs were much higher than those for ssODNs with no blocking mutation. We have also demonstrated that Cas9 protein/sgRNA ribonucleoprotein complexes (Cas9-RNPs) can dramatically reduce the re-cutting of the edited sites.
A Dual NIR-Band Lock-In Pixel CMOS Image Sensor With Device Optimizations for Remote Physiological Monitoring (2021)

A 7.1- μm-pitch lock-in pixel (LIP) CMOS image sensor (CIS) that is capable of simultaneously phasing with two different near-infrared-band (NIR-band) light pulses is developed for remote physiological measurement, particularly a heart rate variability (HRV) signal monitor. The proposed dual NIR-band lock-in operation is realized by a four-tap-wise charge modulation with adjacent two-tap LIPs by means of a column-interdigital pixel driving scheme combining with in-LIP lateral electric field modulators (LEFMs). For attaining the weak HRV signal, the implemented CIS achieves a subelectron temporal noise of 0.67 e <sup xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">-</sup> <sub xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">rms</sub> at 64 times correlated multiple sampling (CMS) and a high charge modulation contrast (MC) up to 96% at maximum. These remarkable properties primarily result from the in-LIP dark current and LEFM controlling optimizations proposed in device domain. The experimental results show that the developed CIS exhibits not only a 98.5% accuracy in HRV signal capture with -39.1-dB signal-to-background ratio (SBR) against a fluctuant brightness ambient light but also a moderate artificial motion robustness benefited from the proposed dual NIR-band lock-in technique.
Vortex avalanches at one thousandth the superconducting transition temperature (1996)

We study the nonequilibrium dynamics of vortex motion at millikelvin temperatures in untwinned single crystals of ${\mathrm{YBa}}_{2}$${\mathrm{Cu}}_{3}$${\mathrm{O}}_{7\mathrm{\ensuremath{-}}\mathrm{\ensuremath{\delta}}}$. Above threshold fields of many tesla, flux jumps appear in the magnetic hysteresis B(H). These jumps correspond to a change of 750 vortices, on average, under our micrometer-sized Bi Hall probes. Not only are the threshold fields large, but they, and the characteristics of the flux jumps themselves, are essentially independent of magnet ramp rate or sample thickness, militating against a thermally triggered instability. Moreover, the threshold differs significantly on the ascending and descending branches of the hysteresis loop. We argue for a dynamical origin for these vortex avalanches and invoke a sandpile analogy to guide our detailed explorations of the H-T plane. \textcopyright{} 1996 The American Physical Society.
TCR vaccines for active immunotherapy of T cell malignancies (1997)

We have developed a TCR-based vaccine approach for the treatment of T cell malignancies. TCR genes were isolated from C6VL, a T cell tumor of C57BL/Ka origin. The transmembrane encoding domains of the TCR genes were replaced by sequences encoding for phosphatidylinositol-linked cell surface expression. A high expressing cell line was produced by transfection and amplification of the TCR genes. Large quantities of soluble native C6VL TCR-alphabeta protein was obtained by treating the high-expressing cells with a specific phospholipase and purifying the released TCR by affinity chromatography. Following vaccination with the TCR linked to keyhole limpet hemocyanin, specific anti-TCR humoral responses were induced. Both the carrier protein and an adjuvant were required for optimal responses. Hyperimmune serum from vaccinated mice reacted specifically with C6VL cells, and the immunizations did not affect the TCR repertoire, which suggested that the immune response was Id specific. The TCR-vaccinated mice were specifically protected from a lethal number of C6VL tumor cells. B cell-deficient mice were not protected by TCR vaccinations. Similarly, TCR-immunized mice depleted of CD8+ cells prior to tumor challenge were not protected. Thus, C6VL TCR vaccine effectively stimulated tumor protection, which depends on the presence of both B cells and CD8+ T cells.
Projection optics for extreme ultraviolet lithography (EUVL) micro-field exposure tools (METs) with a numerical aperture of 0.5 (2013)

In support of the Extreme Ultraviolet Lithography (EUVL) roadmap, a SEMATECH/CNSE joint program is under way to develop 13.5 mn R and D photolithography tools with small fields (micro-field exposure tools [METs]) and numerical apertures (NAs) of 0.5. The transmitted wavefront error of the two-mirror optical projection module (projection optics box [FOB]) is specified to less than 1 mn root mean square (RMS) over its 30 &mu;m x 200 &mu;m image field. Not accounting for scatter and flare losses, its Strehl ratio computes to 82%. Previously reported lithography modeling on this system [1] predicted a resolution of 11 mn with a k-factor of 0.41 and a resolution of 8 mn with extreme dipole illumination. The FOB's magnification (5X), track length, and mechanical interfaces match the currently installed 0.3 NA FOBs [2] [3] [6], so that significant changes to the current tool platforms and other adjacent modules will not be necessary. The distance between the reticle stage and the secondary mirror had to be significantly increased to make space available for the upgraded 0.5 NA illumination modules [1].

Coding and sampling for compressive x-ray diffraction tomography (2013)

Coded apertures and energy resolving detectors may be used to improve the sampling efficiency of x-ray tomography and increase the physical diversity of x-ray phenomena measured. Coding and decompressive inference enable increased molecular specificity, reduced exposure and scan times. We outline a specific coded aperture x-ray coherent scatter imaging architecture that demonstrates the potential of such schemes. Based on this geometry, we develop a physical model using both a semi-analytic and Monte Carlo-based framework, devise an experimental realization of the system, describe a reconstruction algorithm for estimating the object from raw data, and propose a classification scheme for identifying the material composition of the object at each location
Electronic Structure and Photovoltaic Properties of n-Type Amorphous In-Ga-Zn-O and p-Type Single Crystal Si Heterojunctions (2011)

The photovoltaic properties and electronic structures of amorphous In-Ga-Zn-O (a-IGZO)/p-type Si heterojunctions were investigated. An optimized solar cell with a conversion efficiency of 5.3% was obtained by vacuum annealing at 300°C. The short circuit current was 28.1 mA·cm−2, which approaches the theoretical limit without an electron back reflector. The open circuit voltage (Voc) was 0.31 V, which was limited by the built-in potential of 0.39 V. This result combined with hard x-ray photoemission spectroscopy provided the electron affinity and ionization potential of a-IGZO, indicating the low VOC was controlled by the deep conduction band bottom of a-IGZO.

Coordination and Trajectory Prediction for Vehicle Interactions via\n Bayesian Generative Modeling (2019)

Coordination recognition and subtle pattern prediction of future trajectories\nplay a significant role when modeling interactive behaviors of multiple agents.\nDue to the essential property of uncertainty in the future evolution,\ndeterministic predictors are not sufficiently safe and robust. In order to\ntackle the task of probabilistic prediction for multiple, interactive entities,\nwe propose a coordination and trajectory prediction system (CTPS), which has a\nhierarchical structure including a macro-level coordination recognition module\nand a micro-level subtle pattern prediction module which solves a probabilistic\ngeneration task. We illustrate two types of representation of the coordination\nvariable: categorized and real-valued, and compare their effects and advantages\nbased on empirical studies. We also bring the ideas of Bayesian deep learning\ninto deep generative models to generate diversified prediction hypotheses. The\nproposed system is tested on multiple driving datasets in various traffic\nscenarios, which achieves better performance than baseline approaches in terms\nof a set of evaluation metrics. The results also show that using categorized\ncoordination can better capture multi-modality and generate more diversified\nsamples than the real-valued coordination, while the latter can generate\nprediction hypotheses with smaller errors with a sacrifice of sample diversity.\nMoreover, employing neural networks with weight uncertainty is able to generate\nsamples with larger variance and diversity.\n
Physics of insulating specimen preparation for non-charging Auger electron spectroscopy (2001)

Auger electron spectroscopy (AES) has the capability of providing compositional information with excellent spatial resolution. However, charging is known to be a major obstacle to the characterization of insulating materials. This paper discusses a novel technique using focused ion beam (FIB) for the preparation of thin specimens to overcome charging during AES analysis of insulating materials. A double layer model (DLM) was applied to calculate the 'effective thickness' of a Nextel-720 fibre/alumina ceramic matrix composite (CMC) for successful AES analysis with no charging compared to a relatively thick CMC sample. Similarly, the thickness for 50 industrially important solid oxides was calculated using our predictive method for non-charging AES analysis.
Analysis of Whole-Exome Sequencing Data for Alzheimer Disease Stratified by APOE Genotype (2019)

Synthesis, Biological Evaluation, and Molecular Docking of New Benzimidazole-1,2,3-Triazole Hybrids as Antibacterial and Antitumor Agents (2022)

A new series of benzimidazole-1,2,3-triazole hybrids have been successfully accomplished by the Click chemistry of different aromatic azides and propargylated benzimidazole (4). The structural confirmations of the molecules were done by NMR, mass spectrometry, IR, and other techniques. All the newly synthesized compounds were tested for their antibacterial potentialities against two Gram-positive and two Gram-negative bacterial strains. The antibacterial results displayed comparable activity of two compounds (7) and (9) with the standard drug against S. aureus and S. epidermidis. The anticancer results showed that compounds (6, 7, 10, and 14) were more promising than tamoxifen toward MCF-7 cells. Whereas, compound (6) was the most potent molecule with IC50 3.23, 6.56, and 5.35 μM toward MCF-7, HepG2, and HCT-116 cell lines, respectively. The molecular docking showed that the synthesized molecules 6, 7, 10, and 14 with promising cytotoxicity displayed similar interaction like erlotinib with EGFR protein. These results suggest that these benzimidazole derivatives are promising lead molecules for chemotherapeutics and microbial infections.

Advances in modeling polarimeter performance (2017)

Artifacts in polarimeters are apparent polarization features which are not real but result from the systematic errors in the polarimeter. The polarization artifacts are different between division of focal plane, spectral, and time modulation polarimeters. Artifacts result from many sources such as source properties, micropolarizer arrays, coatings issues, vibrations, and stress birefringence. A modeling examples of polarization artifacts due to a micro-polarizer array polarimeter is presented.
Human platelet αIIbβ3 integrin binding affinity and specificity of SJ874: antiplatelet efficacy versus aspirin (2000)

SJ874 is a potent and specific platelet glycoprotein IIb/IIIa antagonist with high affinity for and tight association with human platelets. These data suggest that SJ874 might have good antiplatelet utility for inhibiting formation both of platelet micro-aggregates and of macro-aggregates of platelets and a long duration of action in humans due to its slow dissociation from human platelets.
Large Scale Synthesis and Properties of the Novel Sucrose Aspartate Surfactants (2000)

Mostly being derived from renewable resources, these novel biodegradable surfactants provided favourable application properties.
CHANGES IN ASPHALT CHEMISTRY AND DURABILITY DURING OXIDATION AND POLYMER MODIFICATION (2001)

The Gulf Countries' environmental conditions are very severe. The temperature zoning study indicate that more than half of Gulf areas experience a maximum seven consecutive days pavement temperature of 76°C (Al-Abdul Wahhab et al., 1997). This has resulted in damage to the road networks in the form of cracking, rutting and deformation. Polymer modification of asphalt is required to increase the resistance to permanent deformation at relatively high temperatures without adversely affecting the properties of the asphalts at low temperature. In this work chemical and performance-related properties of fresh, oxidized, and polymer modified asphalts were evaluated. The physical properties and performance characteristics of asphalts were found to depend on the chemical composition of asphalt. The interactions of polar functionalities actually present or formed during oxidative aging or due to polymer modification, influence the viscosity and related flow properties. The changes in composition of fresh, oxidized and polymer-modified asphalts can be clearly identified from Infrared spectroscopy. NMR spectroscopy enables detailed information about the Carbon-and-hydrogen-types and average molecular/structural parameters of asphalt without separating it into different components.
