Variations of Interface Potential Barrier Height and Leakage Current of (Ba, Sr)TiO₃ Thin Films Deposited by Sputtering Process (1996)

Variations of the leakage current behaviors and interface potential barrier height (Φ β ) of rf-sputter deposited (Ba, Sr)TiO₃ (BST) thin films with thicknesses ranging from 20 nm to 150 nm are investigated as a function of the thickness and bias voltages. The top and bottom electrodes are dc-sputter-deopsited Pt films. Φ β critically depends on the BST film deposition temperature, postannealing atmosphere and time after the annealing. The postannealing under N₂ atmosphere results in a high interface potential barrier height and low leakage current. Maintaining the BST capacitor in air for a long time reduces the Φ β from about 2.4 eV to 1.6 eV due to the oxidation. Φ β is not so dependent on the film thickness in this experimental range. The leakage conduction mechanism is very dependent on the BST film thickness; the 20 nm thick film shows tunneling current, 30 and 40 nm thick films show Schottky emission current.
Preparation and Properties of Some Fluoroalcohol-Ethylene Oxide Adducts. (1976)

Polyoxyethylene fluoroethers, CF3 (CF2) mCH2O (C2H4O) pH and H (CF2CF2) n CH2O (C2H4O) pH (m=2, 6; n=2, 3, 4; p=3, 5, 10) were prepared by the addition of ethylene oxide (EO) to fluoroalcohols in the presence of a base catalyst and their physicochemical properties-cloud point, surface tension, foaming property, and emulsifying power-weremeasured. The effects of the number of EO moles added and the carbon chain length of starting alcohols onthe surface activities were clarified, and the following results were obtained.1) Cloud points of aqueous solution of those adducts were found to be higher with an increase in the ni mber of oxyethylene units.2) Aqueous surface tensions of those adducts decreased with increasing of the carbon chain length of starting alcohols. However, 5 moles EO adducts generally gave the lowest aqueous surface tension in each of the series other than H (CF2CF2) 2CH2O (C2H4O) pH. (p=3, 5, 10).3) With the exception of ethylene glycol solutions of CF3 (CF2) 6CH2O (C2H4O) pH (p=0, 1, 3, 5, 10), the surface tensions of ethylene glycol solutions of those adducts decreased with increasing of the carbon chain length of starting alcohols and the number of oxyethylene units.4) CF3 (CF2) 6CH2O (C2H4O) pH (p=5, 10) and H (CF2CF2) 4CH2O (C2H4O) 10H showed a good foaming property.5) The adducts had strong emulsifying powers toward xylene but weak emulsifying powers toward liquid paraffin.
Periodic Large‐Area Metallic Split‐Ring Resonator Metamaterial Fabrication Based on Shadow Nanosphere Lithography (2009)

A fast and cheap, large-area (>1 cm(2)), high-coverage fabrication technique for periodic metallic split-ring resonator metamaterials is presented, which allows control of inner- and outer-ring diameters, gap angles, as well as thickness and periodicity. This method, based on shadow nanosphere lithography, uses tilted-angle-rotation thermal evaporation onto Langmuir-Blodgett-type monolayers of close-packed polystyrene nanospheres. Excellent agreement of the process parameters with a simplified model is demonstrated. Pronounced, tunable optical metamaterial resonances in the range of 100 THz are consistent with simulations.
Spinodal decomposition in binary mixtures (1996)

We study the early stage of the phase separation of a binary mixture far from its critical point of demixing. Whenever the mixture of two mutually repulsive species is quenched to a temperature below its critical point of miscibility, the effect of the enthalpic repulsive force prevails upon the entropic tendency to mix, so that the system eventually separates itno two coexisting phases. We have developed a highly nonlinear model, in close analogy with the linear theory of Cahn and Hilliard, where a generalized free energy is defined in terms of two parameters \ensuremath{\psi} and a, the first describing the equilibrium composition of the two phases, ad the second denoting a characteristic length scale that is inversely proportional to the equilibrium surface tension. The linear stability analysis predicts that any perturbation of the initial mixture composition with wave number k smaller than \ensuremath{\surd}2\ensuremath{\psi} /a will grow exponentially in time, with a maximum growth corresponding to ${\mathit{k}}_{\mathrm{max}}$= \ensuremath{\surd}\ensuremath{\psi} /a. A numerical solution of the equation shows that nonlinear effects saturate the exponential growth, and that the concentraiton distribution tends to a steady state, peroidic profile with wavelength \ensuremath{\lambda}=2\ensuremath{\pi}a/ \ensuremath{\surd}\ensuremath{\psi} corresponding to the fastest growing mode of the linear regime. The main result of our theoretical model is that this steady state does not depend on the form of the initial perturbation to the homogeneous composition profile. \textcopyright{} 1996 The American Physical Society.
STATISTICAL-BASED SUB-BAND FILTERING TECHNIQUE FOR DIGITAL MAMMOGRAM ENHANCEMENT (2003)

Early detection and diagnosis of breast cancer markedly increases survival rate. Digital mammography is believed to help breast image experts to detect breast cancer early. Accurate diagnosis also depends on the quality of the image presented to the experts. This study addresses the quality improvement of the image. A statistically based sub-band filtering method is applied to enhance the mass and calcification shown in the digital mammograms by inhibiting noise. The method is based on sub-band transformation due to its decomposition characteristic and includes two steps: noise inhibition and boundary enhancement. Contrast ratios and frequency responses are measured to evaluate the enhancement performance and the distortion affect, respectively, to validate the effectiveness of the proposed technique. By comparing the enhancement performance of proposed and conventional methods, a phantom mammogram image that consists of similar mammographic microcalcifications, breast gland and well-circumscribed mass is designed for simulation experiment. Moreover, the real mammograms with microcalcifications are also applied on representing the efficient enhancement ability by the proposed method in this paper. Results in this study demonstrate that the proposed method improves the quality of the image more than other enhancement methods, according to these two criteria. The comparison results show that not only the image quality is improved but also within less image distortion.

Reconstruction and analysis of the genome-scale metabolic model of schizochytrium limacinum SR21 for docosahexaenoic acid production (2015)

The reconstructed GSMM, iCY1170_DHA, could be used to elucidate the mechanism by which DHA is synthesized in S. limacinum and predict the requirements of abundant acetyl-CoA and NADPH for DHA production as well as the enhanced yields achieved via supplementation with six amino acids, malate, and citrate.
RET: a poly A-trap retrovirus vector for reversible disruption and expression monitoring of genes in living cells (1999)

Gene trapping is a form of insertional mutagenesis that causes disruption of gene function. Here we report the construction and extensive examination of a versatile retrovirus vector, RET (removable exon trap). The RET vector uses an improved poly A-trap strategy for the efficient identification of functional genes regardless of their expression status in target cells. A combination of a potentially very strong splice acceptor and an effective polyadenylation signal assures the complete disruption of the function of trapped genes. Inclusion of a promoterless GFP cDNA in the RET vector allows the expression pattern of the trapped gene to be easily monitored in living cells. Finally, because of loxP-containing LTRs at both ends, the integrated proviruses can be removed from the genome of infected cells by Cre-mediated homologous recombination. Hence, it is possible to attribute the mutant phenotype of gene-trapped cells directly to RET integration by inducing phenotypic reversion after provirus excision. The RET system can be used in conjunction with cell lines with functional heterozygosity, embryonic stem cells, lineage-committed cell lines that differentiate in response to specific inducing factors and other responsive cell lines that can be selected by virtue of their induced green fluorescence protein expression.

Early Repolarization Syndrome; Mechanistic Theories and Clinical Correlates (2016)

The early repolarization (ER) pattern on the 12-lead electrocardiogram is characterized by J point elevation in the inferior and/or lateral leads. The ER pattern is associated with an increased risk of ventricular arrhythmias and sudden cardiac death (SCD). Based on studies in animal models and genetic studies, it has been proposed that J point elevation in ER is a manifestation of augmented dispersion of repolarization which creates a substrate for ventricular arrhythmia. A competing theory regarding early repolarization syndrome (ERS) proposes that the syndrome arises as a consequence of abnormal depolarization. In recent years, multiple clinical studies have described the characteristics of ER patients with VF in more detail. The majority of these studies have provided evidence to support basic science observations. However, not all clinical observations correlate with basic science findings. This review will provide an overview of basic science and genetic research in ER and correlate basic science evidence with the clinical phenotype.
Automated Pure-Tone Audiometry: An Analysis of Capacity, Need, and Benefit (2008)

Although certain jobs could be affected, the gap between capacity and need is so great that automated audiometry will not significantly affect employment. Automation could increase the number of hearing impaired patients that could be served. The reallocation of personnel time would be a positive change for our patients and our profession.
Complete Genome Sequence of <i>emm</i> 1 Streptococcus pyogenes A20, a Strain with an Intact Two-Component System, CovRS, Isolated from a Patient with Necrotizing Fasciitis (2013)

Here, we announce the complete sequence of Streptococcus pyogenes A20. This strain was isolated from a patient with necrotizing fasciitis. Given that A20 harbors an intact two-component system, CovRS, the discovery of its genome sequence provides more insight into the pathogenesis of a pandemic emm1 strain.
Substituted 2-(2-hydroxyphenyl)benzimidazoles as potential agents for the control of periodontal diseases (1987)

A series of 16 substituted 2-(2-hydroxphenyl)benzimidazoles was synthesized and evaluated in vitro for antibacterial activity against bacteria associated with periodontal diseases. Several compounds demonstrated a high level of activity, in tube dilution assay, against Actinomycetes viscosus and Bacteriodes gingivalis. These results indicate that several of these compounds may serve as topical antibacterial agents for the control of acute marginal inflammatory gingivitis and periodontitis.
Synergistic Effect of Polysaccharide Gums and Antimicrobial Agents on Susceptibility and Protein Expression of Select Pathogenic Microorganisms in Milk (2018)

The quest for the use of natural ingredients as preservatives and antimicrobial agents is rising. Polysaccharide gums are usually used as emulsifying agents and as preservatives. The objective of this study was to investigate the combined effect of five different polysaccharide gums and antimicrobial agents on growth, susceptibility and protein expression of select pathogenic microorganisms in milk. Antimicrobial susceptibility and protein concentration were determined by disc diffusion and Pierce BCA assay, respectively. The proteome pattern and the number of protein spots were determined by two-dimensional gel electrophoresis. The results showed that xanthan (6.68±0.02 Log CFU/mL) caused the most growth inhibition of Salmonella enterica, compared to the control. Inclusion of pectin led to a significant (P<0.0001) 2-log reduction of Salmonella enterica during a 2-day refrigerated storage (4 oC). The highest inhibition zones (20.50±0.70) was observed in E. coli O157:H7 exposed to carrageenan-maltodextrin-cefixime. The proteome pattern was impacted by the gums with protein band of size 30kDa being the most prominent band. The highest number of protein spots (35) were obtained in locust bean treated samples. These findings indicated that tested gums affected microbial protein expression and were effective in inhibitory activity against tested pathogens specifically Escherichia coli O157:H7, thus gums hold great promise as some antimicrobial agents. Further characterization of protein targets is warranted.
A single-chain antibody generation system yielding CAR-T cells with superior antitumor function (2021)

Cancer immunotherapy using T cells redirected with chimeric antigen receptor (CAR) has shown a lot of promise. We have established a single-chain antibody (scFv) generation system in which scFv library-expressing CAR-T cells can be screened appropriately based on their antitumor functions. A variable region library containing the variable and J regions of the human immunoglobulin light or heavy chain was fused with the variable region of a heavy or light chain encoded by an existing tumor-specific antibody to generate a new scFv library. Then, scFv library-expressing CAR-T cells were generated and stimulated with target cells to concentrate the antigen-specific population. Using this system, target-specific recognition of CAR-T cells appeared to be finely tuned by selecting a new variable region. Importantly, we have demonstrated that the newly optimized scFv-expressing CAR-T cells had better proliferation capacity and durable phenotypes, enabling superior reactivity against advanced tumors in vivo in comparison with the original CAR-T cells. Therefore, the optimization of an scFv is needed to maximize the in vivo antitumor functions of CAR-T cells. This system may allow us to adjust an immunological synapse formed by an scFv expressed by CAR-T cells and a target antigen, representing an ideal form of CAR-T-cell immunotherapy.
“Clicking” Gene Therapeutics: A Successful Union of Chemistry and Biomedicine for New Solutions (2018)

The use of nucleic acid, DNA and RNA, based strategies to disrupt gene expression as a therapeutic is quickly emerging. Indeed, synthetic oligonucleotides represent a major component of modern gene therapeutics. However, the efficiency and specificity of intracellular uptake for nonmodified oligonucleotides is rather poor. Utilizing RNA based oligonucleotides as therapeutics is even more challenging to deliver, due to extremely fast enzymatic degradation of the RNAs. RNAs get rapidly degraded in vivo and demonstrate large off-target binding events when they can reach and enter the desired target cells. One approach that holds much promise is the utilization of "click chemistry" to conjugate receptor or cell specific targeting molecules directly to the effector oligonucleotides. We discuss here the applications of the breakthrough technology of CuAAC click chemistry and the immense potential in utilizing "click chemistry" in the development of new age targeted oligonucleotide therapeutics.
An Information Theoretic Framework for Camera and Lidar Sensor Data Fusion and its Applications in Autonomous Navigation of Vehicles. (2014)

It has been five years when I boarded that flight to DTW (a completely different world) to follow my dreams of getting a PhD. Since then it’s been a journey full of learning and I have tried to soak in as much knowledge as I could. As I stand at the end of this road, I would like to thank those who are an integral part of this beautiful journey. First of all I would like to thank my supervisor Ryan Eustice for his excellent guidance and support throughout my graduate studies. I really appreciate his patience to discuss and explain even the most trivial questions that I have asked him several times. He always had time to meet and discuss any problem. He always made sure that I am making progress and always guided me towards the right path. Thanks Ryan for always keeping me on track by your formula of “Must, Should and Would be nice”. I will remember this mantra of success for the rest of my life. Next I would like to thank my co-advisor Silvio Savarese for his invaluable inputs on my research. Those weekly meetings helped me to stay focused and steadily progress towards my goal. I would also like to thank my committee members Alfred Hero and Honglak Lee for their valuable suggestions at times.
STEFANN: Scene Text Editor Using Font Adaptive Neural Network (2020)

Textual information in a captured scene plays an important role in scene interpretation and decision making. Though there exist methods that can successfully detect and interpret complex text regions present in a scene, to the best of our knowledge, there is no significant prior work that aims to modify the textual information in an image. The ability to edit text directly on images has several advantages including error correction, text restoration and image reusability. In this paper, we propose a method to modify text in an image at character-level. We approach the problem in two stages. At first, the unobserved character (target) is generated from an observed character (source) being modified. We propose two different neural network architectures - (a) FANnet to achieve structural consistency with source font and (b) Colornet to preserve source color. Next, we replace the source character with the generated character maintaining both geometric and visual consistency with neighboring characters. Our method works as a unified platform for modifying text in images. We present the effectiveness of our method on COCO-Text and ICDAR datasets both qualitatively and quantitatively.
Flow cytometric detection of activated mouse integrin αIIbβ3 with a novel monoclonal antibody (2002)

JON/A(PE) is the first tool for direct assessment of integrin alphaIIbbeta3 activation in mice. Furthermore, JON/A(FITC) and JON/A(PE) provide the first examples of fluorescent antibody derivatives with identical antigenic specificity that allow the discrimination between the resting and the activated state of an integrin.
Hexagonal sensor with imbedded analog image processing for pattern recognition (2002)

The authors present a multimodule focal plane processing sensor architecture which provides high-resolution (up to 512 /spl times/ 512 pixels) multiscale real-time analog edge extraction for robot vision. The hexagonal CMOS sensor uses a multiport addressing architecture of the pixel array to apply external multiscale analog spatial convolution followed by edge detection. The sensor architecture and its peripheral analog filtering modules are described, and results obtained from a 256 /spl times/ 256 prototype are presented. This analog satellite processing approach may be extended to various types of computational sensors, including a 3-D rangefinder, motion sensors, and tactile perception devices.
