Tuning Multiphase Amphiphilic Rods to Direct Self-Assembly (2011)

New methods to direct the self-assembly of particles are highly sought after for multiple applications, including photonics, electronics, and drug delivery. Most techniques, however, are limited to chemical patterning on spherical particles, limiting the range of possible structures. We developed a lithographic technique for fabrication of chemically anisotropic rod-like particles in which we can specify both the size and shape of particles and implement multiple diverse materials to control interfacial interactions. Multiphase rod-like particles, including amphiphilic diblock, triblock, and multiblock were fabricated in the same template mold having a tunable hydrophilic/hydrophobic ratio. Self-assembly of diblock or triblock rods at a water/oil interface led to the formation of bilayer or ribbon-like structures.
60GHz dielectrically stabillized monolithic voltage controlled oscillator (1995)

This paper reports a 60GHz dielectrically stabilized monolithic voltage controlled oscillator(VCO) for the first time. The developed MMIC is composed of a VCO with a dielectric resonator (DR) and a buffer amplifier utilizing an AIGaAs/InGaAs heterojunction FET (HJFET) as an active element, and a drain DC-biased HJFET as a variable reactance element. The fabricated MMIC has exhibited an oscillation frequency control of SS MHz/V with 6.9dBm output power, -80dBc/Hz(100kHz off-carier) phase noise and -4.1ppm/°C frequency stabiliy at 60.0GHz.

Markov chain Monte Carlo (McMC) estimation of spectral induced polarization (SIP) as a distribution of simple Debye relaxations (2010)

Proposed empirical relationships between frequency dependent complex electrical resistivity and key physical properties, such as grain or pore throat size, may allow hydraulic conductivity to be indirectly estimated from variable frequency electrical measurements, often referred to as spectral induced polarization (SIP). The SIP response may be described by several models, each providing one or more estimated values of relaxation time and chargeability, and a variety of additional parameters. Recent interest has been shown in modelling the SIP response as the coupling of a large number of simple Debye responses, each fully described by the two parameters of relaxation time and chargeability, and with no requirement for additional model parameters. This deterministic approach allows the SIP response to be matched with high accuracy, but since the mean, mode and median relaxation times of the total chargeability may differ widely, none of these statistics is sufficient to summarise the SIP response adequately. We introduce a parsimonious set of descriptors which efficiently summarises the distribution of Debye relaxations, with minimal loss of the information content in the electrical measurements. Our method applies a Markov chain Monte Carlo algorithm to provide a Bayesian estimation of the relaxation distribution parameters, and does not require an accurate prior estimation of DC resistivity. The distribution parameters may be combined with electrical-physical relationships identified in other studies, to give stochastic estimates of hydraulic conductivity. We apply our approach to electrical spectra measured in the laboratory and in field surveys, and we compare our results with those from deterministic methods.
Experimental Comparison of No-Guard-Interval-OFDM and Nyquist-WDM Superchannels (2012)

We experimentally compare the performance of NGI-OFDM and Nyquist-WDM superchannels with same spectral efficiency in both back-to-back and transmission cases. Because of lower inter-carrier interference, the Nyquist-WDM has better performance than the NGI-OFDM.

Information Obfuscation of Graph Neural Networks (2020)

While the advent of Graph Neural Networks (GNNs) has greatly improved node and graph representation learning in many applications, the neighborhood aggregation scheme exposes additional vulnerabilities to adversaries seeking to extract node-level information about sensitive attributes. In this paper, we study the problem of protecting sensitive attributes by information obfuscation when learning with graph structured data. We propose a framework to locally filter out pre-determined sensitive attributes via adversarial training with the total variation and the Wasserstein distance. Our method creates a strong defense against inference attacks, while only suffering small loss in task performance. Theoretically, we analyze the effectiveness of our framework against a worst-case adversary, and characterize an inherent trade-off between maximizing predictive accuracy and minimizing information leakage. Experiments across multiple datasets from recommender systems, knowledge graphs and quantum chemistry demonstrate that the proposed approach provides a robust defense across various graph structures and tasks, while producing competitive GNN encoders for downstream tasks.
Diamond-Enhanced Insert: New Compositions and Shapes for Drilling Soft-to-Hard Formations (1993)

Abstract Increased penetration rates, accompanied by longer bit life, have always been primary objectives of both rock bit manufacturers and drilling contractors. Diamond-enhanced tungsten carbide inserts have been employed successfully in the gage row of soft formation three-cone rock bits. However, the current semi-round top geometry used in the manufacture of diamond-enhanced inserts has limitations. Two such limitations are slower penetration rates when replacing chisel-type gage inserts in certain soft formations and premature breakage in medium-to-hard formations (IADC 6-2-7 to 7-3-7 type drilling). This paper reviews recent progress in the development of tougher diamond-enhanced inserts and new geometries, such as the inclined chisel gage inserts. Laboratory test results are compared between the new, tougher enhanced inserts, the standard enhanced inserts and the standard tungsten carbide grades. Successful field tests of diamond-enhanced heel inserts used in medium-to-hard formations will be reviewed. The impact on bit life, penetration rates and drilling costs of the new enhanced insert composition and geometry technology also will be discussed.

An Antifungal Protein from the Culinary-Medicinal Beech Mushroom, Hypsizygus marmoreus (Peck) Bigel. (Agaricomycetideae) (2011)

An antifungal protein (HM-af) was purified from the culinary-medicinal mushroom Hypsizygus marmoreus. The results of sodium dodecyl sulfate polyacrylamide gel electrophoresis and matrix-assisted laser desorption ionization time-of-flight mass spectrometry of HM-af indicated that its molecular mass was 9.5 kDa. The N-terminal amino acid sequence of HM-af showed homology to ribonuclease H from Clostridium thermocellum. HM-af showed the antifungal activity against Flammulina velutipes.
Role of Mitogen-Activated Protein Kinases, Early Response Protooncogenes, and Activator Protein-1 in Cell Signaling by Asbestos (2000)

Cell signaling by pathogenic minerals may initiate the transactivation of genes that are critical to carcinogenesis and fibroproliferative diseases of the lung and pleura. We have shown previously that stimulation of the mitogen-activated protein kinase (MAPK) cascade by asbestos fibers leads to phosphorylation events involved in transactivation of lun and Fos proteins that comprise the activator protein-1 (AP-1) transcription factor. Recently, we have also used AP-1 luciferase reporter transgenic mice and immunocytochemistry to show that transactivation of AP-1 occurs in bronchiolar and alveolar epithelial cells after inhalation of asbestos fibers. After inhalation of asbestos, epithelial cells of the lung also show increased immunoreactivity of pliosphorylated extracellular signal regulated kinases (ERKs 1/2) at sites of fibrogenesis. The availability of lung epithelial cell-specific promoters has allowed the creation of transgenic mice with mutations in the transactivation domains of key receptors and protein intermediates that comprise the MAPK signaling cascade. These rodent models may reveal whether cell signaling events initiated by mineral dusts in epithelial cells are critical to the development of cell proliferation, apoptosis, and lung disease.
Fat accumulation, fibrosis, fiber‐type switching, and a reduction in specific force production following rotator cuff tear (2012)

Rotator cuff tears often cause pain and decreased mobility, and are associated with atrophy of muscle fibers, fibrosis and accumulation of fat in the muscle, collectively referred to as “fatty atrophy.” Previous studies have demonstrated that surgical repair of torn cuff muscles does not reduce fatty atrophy. As the molecular etiology of fatty atrophy remains unknown, gaining greater insight into the mechanisms that lead to the development of fatty atrophy will improve the treatment of rotator cuff tears. Using a rat model, we measured single fiber contractility, fiber type distribution, and expression of various mRNA and miRNA transcripts involved in lipid accumulation and matrix synthesis in torn and intact cuff muscles. We hypothesized that following chronic rotator cuff tear, there would be a decrease in specific force, accumulation of type IIb fibers, and an upregulation of adipogenic and fibrogenic genes. Thirty days after inducing the tear, cuff muscles had a substantial decrease in mass and force production, a dramatic accumulation of type IIb fibers, and a marked increase in fatty macrophages and caspase positive fibers. While there was an increase in several mRNAs and miRNAs associated with fibrosis, only modest changes in canonical adipogenesis transcripts were observed. Combined, the fatty atrophy phenotype in torn rotator cuff muscles may be a result of autophagy rather than bona fide adipogenesis.

Physical Cue based Depth-Sensing by Color Coding with Deaberration Network. (2019)

Color-coded aperture (CCA) methods can physically measure the depth of a scene given by physical cues from a single-shot image of a monocular camera. However, they are vulnerable to actual lens aberrations in real scenes because they assume an ideal lens for simplifying algorithms. In this paper, we propose physical cue-based deep learning for CCA photography. To address actual lens aberrations, we developed a deep deaberration network (DDN) that is additionally equipped with a self-attention mechanism of position and color channels to efficiently learn the lens aberration. Furthermore, a new Bayes L1 loss function based on Bayesian deep learning enables to handle the uncertainty of depth estimation more accurately. Quantitative and qualitative comparisons demonstrate that our method is superior to conventional methods including real outdoor scenes. Furthermore, compared to a long-baseline stereo camera, the proposed method provides an error-free depth map at close range, as there is no blind spot between the left and right cameras.
Disentangling the Complex Electronic Structure of an Adsorbed Nanographene: Cycloarene C108 (2021)

We combine low-temperature scanning tunneling spectroscopy, CO functionalized tips and algorithmic data analysis to investigate the electronic structure of the molecular cycloarene C108 (graphene nanoring) adsorbed on a Au(111) surface. We demonstrate that CO functionalized tips enhance the visibility of molecular resonances, both in differential conductance spectra and in real-space topographic images without introducing spurious artifacts. Comparing our experimental data with ab-initio density functional theory reveals a remarkably precise agreement of the molecular orbitals and enables us to disentangle close-lying molecular states only separated by 50 meV at an energy of 2 eV below the Fermi level. We propose this combination of techniques as a promising new route for a precise characterization of complex molecules and other physical entities which have electronic resonances in the tip-sample junction.

Effect of a chimeric anti-ganglioside GM2 antibody on ganglioside GM2-expressing human solid tumorsIn vivo (1999)

Ganglioside GM2 is expressed on the surface of neuroblastoma and glioblastoma cells, and may also be detected on lung cancer cells. We reported previously that anti-ganglioside GM2 antibody exhibited strong in vitro anti-tumor activity against adriamycin-resistant cancer cells, which overexpressed ganglioside GM2. In the present study, we examined the in vivo anti-tumor effect of the chimeric anti-ganglioside GM2 antibody, KM966, against human lung and breast carcinoma cells, SBC-3 and MCF-7, and respective adriamycin-resistant clones, SBC-3/ADM and AdrR MCF-7 in BALB/c nu/nu mice. Ratios of tumor volume (T/C) between KM966-treated group and control group were 0.01 for SBC-3, 0.00 for SBC-3/ADM, 0.85 for MCF-7 and 0.34 for AdrR MCF-7 cells, respectively. Nude mice, which were pretreated with anti-asialo GM1 antibody to remove natural killer cells, were transplanted with 4 x 10(7) of SBC-3 and SBC-3/ADM subcutaneously. Seven days later, when tumors had grown to a diameter of over 8 mm, mice began to receive intravenous treatment of 120 microgram/mouse KM966 daily. Fourteen daily treatments induced regression to less than 4-mm diameter in 4/5 SBC-3 tumors and 5/5 of SBC-3/ADM tumors. All SBC-3/ADM tumors disappeared completely, suggesting that KM966 exerts a strong in vivo anti-tumor effect on ganglioside GM2-expressing cancer cells. In KM966-treated mice, the surface of the tumor cells stained positive with anti-human IgG. In addition, numerous leukocytes had infiltrated into the tumor mass. Antibody-dependent cell-mediated cytotoxicity (ADCC) of KM966 against tumor cells was examined in vitro by (51)Cr-release assay and revealed that KM966 induces ADCC activity against ganglioside GM2-expressing tumors. Our results suggest that immunotherapy using KM966 may be useful for the treatment of ganglioside GM2-expressing solid tumors.

Human Chromatic Contrast Sensitivity and Mean Colour (2002)

We report results of an experiment measuring contrast sensitivity as a function of spatial frequency, location in colour space and direction of variation. Stimuli comprised sinusoidal gratings on one side and a uniform field of the same mean colour on the other. The experiment used forced choice to measure thresholds for many observers and numerous spatial frequency-mean colour-direction of variation combinations. Earlier data covered the spatial frequency range from 0.44 to 20 cycles per degree (cpd) and suffered from quantization effects at peak sensitivities. That data showed no meaningful dependence on any other independent variables, such as C*, as would have been expected from common colour difference metrics. The current experiment corrects the quantization effects, seeks more explicitly chroma or hue dependence and extends the low spatial frequency range to 0.19 cpd. We have found only a weak dependence on hue (in addition to the dependence on spatial frequency).

Characterization of InGaN multiquantum well structures for blue semiconductor laser diodes (1997)

In 0.15 Ga 0.85 N/GaN and In0.15Ga0.85N/In0.05Ga0.95N multi quantum well (MQW) structures grown on (0001) sapphire substrates were investigated by high-resolution x-ray diffraction and cross-sectional transmission electron microscopy. The results show that ultrathin MQWs with fairly good crystallinity and precisely controlled clear parallel interfaces were grown. Laser diode structures with MQWs were also studied, and the results suggest that these superlattice structures retain their high quality even after being subjected to high temperatures during the subsequent growth of p-type GaN as the optical guiding layer, p-type GaAlN as the cladding layer, and p-type GaN as the contact layer.
