Carrier transport in a three-layered electroluminescent device (1996)

The carrier transport mechanism has been studied in a three-layered electroluminescent (EL) device, which consists of poly(9,9-dialkylfluorene), diamine and perylene derivatives. The time response of EL emission in the three-layered device is completely different for the cases of driving by a forwards- or a reverse-bias field. Under the forwards-bias condition, it shows a slow response, whereas there is a fast response under the reverse-bias condition. Mean carrier mobilities have been estimated from the response time of emission. Mobility under the forwards-bias condition is found to increase with increasing applied field, whereas that under the reverse-bias condition remains constant and larger than that under the forwards-bias condition.
Thermophysical and thermomechanical properties of Norland Optical Adhesives and liquid crystal composites (2008)

Abstract Thermophysical and thermomechanical properties of UV‐cured Norland Optical Adhesives (NOA65) and low molecular weight Liquid Crystal E7 systems were investigated. Thin films of Polymer Dispersed Liquid Crystal were prepared by Polymerization Induced Phase Separation and UV‐curing. Phase diagrams were established using Polarized Optical Microscopy and DSC to determine the lines of nematic to isotropic phase transition as well as the glass transition temperature changes with the system composition. Mechanical measurements were performed in the static and dynamic modes to determine the moduli in terms of the curing time, the temperature and the amount of low molecular weight liquid crystal molecules. Thermomechanical measurements were found to overestimate the glass transition temperature as compared to calorimetric data. Variations of the Young's modulus and the molecular weight defining the mesh size of the network were analyzed in terms of the curing time and liquid crystal concentration. © 2008 Wiley Periodicals, Inc.

Design and Trajectory Estimation of Dynamic Motion Model (2018)

This paper illustrates linear and maneuvering motion model of target trajectories. The trajectory of the target is segmented into varied profiles considering constraints of velocity, acceleration and jerk. The influence of angular jerk, centripetal acceleration and turn radius of dynamic motion model are integrated feature of the proposed model. The mathematical motion models have been designed considering physical laws of motion and vehicle dynamics. The prior research has not focused intensively on the detailed designing of the dynamic motion model. The designed motion models are described in this paper with their vivid dynamic changes under the complexity of an environment and their adaptability to such changes. The tracking of complicated trajectories of moving target using an estimation technique based on Rao-Blackwellization integrated with dynamic motion model has been proposed in this paper as a resolution to solve illustrated tracking complexities. The performance of proposed estimation technique has been illustrated and compared with conventional tracking algorithm of Particle filter and Kalman filter. Furthermore, the proposed estimation technique is validated on the real world convoluted trajectory extracted in simulated environment of Carmaker to illustrate the performance of tracking algorithm.
A Wideband Dual-Mode SIW Cavity-Backed Triangular-Complimentary-Split-Ring-Slot (TCSRS) Antenna (2016)

A cavity-backed triangular-complimentary-split-ring-slot (TCSRS) antenna based on substrate integrated waveguide (SIW) is proposed in this communication. Proposed antenna element is designed and implemented at 28 and 45 GHz for the fifth generation (5G) of wireless communications. The principle of the proposed antenna element is investigated first then the arrays with two and four elements are designed for high-gain operation. Antennas prototype along with their arrays are fabricated using standard printed circuit board (PCB) process at both frequencies-28 and 45 GHz. Measured result shows that the 16.67% impedance bandwidth at 28 GHz and 22.2% impedance bandwidth at 45 GHz is achieved, while maintaining the same substrate height at both frequencies. The measured peak gains of the 2 × 2 antenna array at 30 or 50 GHz are 13.5 or 14.4 dBi, respectively.

New Method for Preparing More Stable Microcapsules for the Entrapment of Genetically Engineered Cells (2005)

In this paper, we studied a new preparation method of microcapsules for entrapment of genetically engineered cells. Polyvinyl alcohol microcapsules having well defined shape, high mechanical strength, good biochemical and permeability properties were prepared by using low temperature physical cross-linking method. Comparing with currently used alginate-polylysine-alginate microcapsules, polyvinyl alcohol microcapsules have much higher mechanical strength. The low temperature physical crosslinking procedure of polyvinyl alcohol is nontoxic to the genetically engineered E. coli DH5alpha cell, which attained high activity in decomposing and metabolizing urea in vitro studies.
An analysis of facial shape and texture for recognition: A large scale evaluation on FRGC ver2.0 (2011)

Traditional approaches to face recognition have utilized aligned facial images containing both shape and texture information. This paper analyzes the contributions of the individual facial shape and texture components to face recognition. These two components are evaluated independently and we investigate methods to combine the information gained from each of them to enhance face recognition performance. The contributions of this paper are the following: (1) to the best of our knowledge, it is the first large-scale study of how face recognition is influenced by shape and texture as all of our results are benchmarked against traditional approaches on the challenging NIST FRGC ver2.0 experiment 4 dataset, (2) we empirically show that shape information is reasonably discriminative, (3) we demonstrate significant improvement in performance by registering texture with dense shape information, and finally (4) show that fusing shape and texture information consistently boosts recognition results across different subspace-based algorithms.

Unsupervised Semantic Feature Discovery for Image Object Retrieval and Tag Refinement (2012)

We have witnessed the exponential growth of images and videos with the prevalence of capture devices and the ease of social services such as Flickr and Facebook. Meanwhile, enormous media collections are along with rich contextual cues such as tags, geo-locations, descriptions, and time. To obtain desired images, users usually issue a query to a search engine using either an image or keywords. Therefore, the existing solutions for image retrieval rely on either the image contents (e.g., low-level features) or the surrounding texts (e.g., descriptions, tags) only. Those solutions usually suffer from low recall rates because small changes in lighting conditions, viewpoints, occlusions, or (missing) noisy tags can degrade the performance significantly. In this work, we tackle the problem by leveraging both the image contents and associated textual information in the social media to approximate the semantic representations for the two modalities. We propose a general framework to augment each image with relevant semantic (visual and textual) features by using graphs among images. The framework automatically discovers relevant semantic features by propagation and selection in textual and visual image graphs in an unsupervised manner. We investigate the effectiveness of the framework when using different optimization methods for maximizing efficiency. The proposed framework can be directly applied to various applications, such as keyword-based image search, image object retrieval, and tag refinement. Experimental results confirm that the proposed framework effectively improves the performance of these emerging image retrieval applications.
Disturbing Behaviours: Ole Ivar Lovaas and the Queer History of Autism Science (2018)

This paper “queers” the history of autism science through an examination of the overlap between the regulation of autism with that of gender and sexuality in the work of Ole Ivar Lovaas. Lovaas is the founder of Applied Behaviour Analysis (ABA), the most commonly used and funded autism intervention today that seeks to extinguish autistic behaviors, primarily among children. Less commonly recognized is Lovaas’ involvement in the Feminine Boy Project, where he developed interventions into the gender identities and behaviors of young people. Turning to Lovaas’ published works, we perform a “history of the present” and argue that a queer disability studies lens opens up the richness of autism as a cultural nexus, and deepens understandings of intersecting and contested histories of science, professional scopes of practice, and dominant futurities. The article makes a significant and timely contribution to understanding the disabling material effects of autism science in the lives of autistic persons. In particular, this case study highlights the need for feminist science studies to further investigate the historical and contemporary links between dominant scientific constructions of disability, gender, and sexuality.
The Biological Mechanisms and Physicochemical Characteristics Responsible for Driving Fullerene Toxicity (2009)

This review provides a comprehensive critical review of the available literature purporting to assess the toxicity of carbon fullerenes. This is required as prior to the widespread utilization and production of fullerenes, it is necessary to consider the implications of exposure for human health. Traditionally, fullerenes are formed from 60 carbon atoms, arranged in a spherical cage-like structure. However, manipulation of surface chemistry and molecular makeup has created a diverse population of fullerenes, which exhibit drastically different behaviors. The cellular processes that underlie observed fullerene toxicity will be discussed and include oxidative, genotoxic, and cytotoxic responses. The antioxidant/cytoprotective properties of fullerenes (and the attributes responsible for driving these phenomena) have been considered and encourage their utilization within the treatment of oxidant-mediated disease. A number of studies have focused on improving the water solubility of fullerenes in order to enable their exploitation within biological systems. Manipulating fullerene water solubility has included the use of surface modifications, solvents, extended stirring, and mechanical processes. However, the ability of these processes to also impact on fullerene toxicity requires assessment, especially when considering the use of solvents, which particularly appear to enhance fullerene toxicity. A number of the discussed investigations were not conducted to reveal if fullerene behavior was due to their nanoparticle dimensions but instead addressed the biocompatibility and toxicity of fullerenes. The hazards to human health, associated with fullerene exposure, are uncertain at this time, and further investigations are required to decipher such effects before an effective risk assessment can be conducted.
Surface Encapsulation Process for Stabilizing Intractable Contaminants (1989)

This paper reports advanced technology for stabilization/solidification of pollutants for their final disposal in the earth. Pollutants are secured in modules fabricated with organic resins. The modules exhibit high-performance pollutant stability versus stresses of handling, transportation, and final disposal. They are set forth for managing pollutants because present stabilization/solidification products do not satisfactorily address such stresses. Organic resins are materials of choice for module fabrication because of their excellent chemical stability. But cost-effective, high-performance pollutant stabilization/solidification by resin modules requires judicious resin selection and module design. Polybutadiene resin was identified as an excellent material for binding pollutant particles and forming aggomerates. Agglomerates holding more than 90% by weight pollutants were readily prepared. They were reinforced by fusing polyethylene resin pellets onto their surfaces, thereby encapsulating aggomerates by seamless resin jackets. Testing of laboratory-scale modules holding toxic wastes demonstrated their outstanding stability under harsh physical, chemical, and mechanical stresses. Based on successful stabilization/solidification of many types of pollutants on a laboratory-scale, the process was scaled up under Department of Energy sponsorship. The work included design and construction of a prototype apparatus for fabricating commercial-size modules. A moldule is cylindrical in shape, has a capacity of 182 L, and is 61 cm high and 61 cm in diameter. In securing sodium sulfate, a pollutant formed in nuclear plants, the module weighs 325 kg, holds 87% by weight salt in a thermoset polybutadiene matrix, and is reinforced by seamless, 0.95-cm-thick, high-density polyethylene jackets.

Characterization of Dextran Sodium Sulfate-Induced Inflammation and Colonic Tumorigenesis in Smad3−/− Mice with Dysregulated TGFβ (2013)

<div><p>There are few mouse models that adequately mimic large bowel cancer in humans or the gastrointestinal inflammation which frequently precedes it. Dextran sodium sulphate (DSS)-induces colitis in many animal models and has been used in combination with the carcinogen azoxymethane (AOM) to induce cancer in mice. <i>Smad3</i><sup>−/−</sup> mice are deficient in the transforming growth factor beta (TGFβ) signaling molecule, <i>SMAD3</i>, resulting in dysregulation of the cellular pathway most commonly affected in human colorectal cancer, and develop inflammation-associated colon cancer. Previous studies have shown a requirement for a bacterial trigger for the colitis and colon cancer phenotype in <i>Smad3<sup>−/−</sup></i> mice. Studies presented here in <i>Smad3<sup>−/−</sup></i> mice detail disease induction with DSS, without the use of AOM, and show a) <i>Smad3</i><sup>−/−</sup> mice develop a spectrum of lesions ranging from acute and chronic colitis, crypt herniation, repair, dysplasia, adenomatous polyps, disseminated peritoneal adenomucinosis, adenocarcinoma, mucinous adenocarcinoma (MAC) and squamous metaplasia; b) the colon lesions have variable galactin-3 (Mac2) staining c) increased DSS concentration and duration of exposure leads to increased severity of colonic lesions; d) heterozygosity of <i>SMAD3</i> does not confer increased susceptibility to DSS-induced disease and e) disease is partially controlled by the presence of T and B cells as <i>Smad3</i><sup>−/−</sup><i>Rag2</i><sup>−/−</sup> double knock out (DKO) mice develop a more severe disease phenotype. DSS-induced disease in <i>Smad3</i><sup>−/−</sup> mice may be a useful animal model to study not only inflammation-driven MAC but other human diseases such as colitis cystica profunda (CCP) and pseudomyxomatous peritonei (PMP).</p></div>
Periodic poling of magnesium-oxide-doped lithium niobate (2002)

In this article, poling characteristics and periodic poling of magnesium-oxide-doped lithium niobate (MgLN) are described. Periodic poling was done by the electric field method, with which uniform gratings were produced. The domain wall velocity as a function of poling field was measured and used to determine conditions for self-terminating periodic poling. A computational model for the self-termination method is also discussed here. In the experiment, it was found that thermal history prior to poling has a significant influence on the poling quality.
Detection of Novel CD Antigens on the Surface of Human Mast Cells and Basophils (2002)

Pseudoinverse Decoding Process in Delay-Encoded Synthetic Transmit Aperture Imaging (2016)

Recently, we proposed a new method to improve the signal-to-noise ratio of the prebeamformed radio-frequency data in synthetic transmit aperture (STA) imaging: the delay-encoded STA (DE-STA) imaging. In the decoding process of DE-STA, the equivalent STA data were obtained by directly inverting the coding matrix. This is usually regarded as an ill-posed problem, especially under high noise levels. Pseudoinverse (PI) is usually used instead for seeking a more stable inversion process. In this paper, we apply singular value decomposition to the coding matrix to conduct the PI. Our numerical studies demonstrate that the singular values of the coding matrix have a special distribution, i.e., all the values are the same except for the first and last ones. We compare the PI in two cases: complete PI (CPI), where all the singular values are kept, and truncated PI (TPI), where the last and smallest singular value is ignored. The PI (both CPI and TPI) DE-STA processes are tested against noise with both numerical simulations and experiments. The CPI and TPI can restore the signals stably, and the noise mainly affects the prebeamformed signals corresponding to the first transmit channel. The difference in the overall enveloped beamformed image qualities between the CPI and TPI is negligible. Thus, it demonstrates that DE-STA is a relatively stable encoding and decoding technique. Also, according to the special distribution of the singular values of the coding matrix, we propose a new efficient decoding formula that is based on the conjugate transpose of the coding matrix. We also compare the computational complexity of the direct inverse and the new formula.
