Convolutional Neural Network Based Bi-prediction Utilizing Spatial and Temporal Information in Video Coding (2019)

With the growing popularity of high-resolution videos, the demand for higher coding efficiency is increasing to cope with multimedia transmission challenges on the communication network. Since conventional linearly weighted bi-prediction does not handle inhomogeneous motion activities inside one block well, in recent works, Convolutional Neural Network (CNN) is explored to tackle inhomogeneous motion by utilizing patch-level information to predict each individual pixel. However, as only two reference blocks are used as input information, those works ignore the variation of pixel values between reference blocks and current block, and ignore the differences between extrapolation and interpolation. This work utilizes both spatial neighboring pixels and temporal display orders as extra inputs for CNN models to further improve the prediction accuracy of a bi-predictor. The extra input information has the following advantages. First, variations among spatial neighboring pixels of both reference blocks and the current block reflect variations between current block and reference blocks. Together with temporal distance, spatial neighboring pixels are able to address extrapolation and interpolation uniformly. Second, spatial neighboring pixels of the current block have a high correlation with current predicted signals, which helps to reduce prediction residuals around the block boundary and alleviate block artifacts. Last, temporal distances help to improve the accuracy of prediction signals based on its ability of reflecting the correlation of video frames. Experimental results show that our proposed network achieves 2.92% and 5.09% bit-rate savings on average compared with HEVC, under Low-Delay B (LDB) and Random-Access (RA) configurations, respectively. As temporal information is used in our network, the LDB and RA configurations share the same networks in this work.
High strength rare earth-iron-boron printed magnets used in a long throw-high force electromagnetic actuator with microfabricated coils (2003)

Rare earth-iron-boron magnets were successfully integrated in a surface micromachined electromagnetic actuator. The magnets are 2000 by 1000 /spl mu/m with thickness varying from 100 to 200 /spl mu/m and were screen printed on electroplated cantilever beams fabricated above 40 turn planer coils on a silicon wafer. The magnetic paste used to form the magnets was made from 40 /spl mu/m diameter spherical powder with a polyimide binder. The residual induction (B/sub r/) was 3000 Gauss (0.3 T) and the intrinsic coercivity (H/sub ci/) was 8050 Oe (644 kA/ m). Displacements of more than 1000 /spl mu/m with 200 mA of current and repulsive and attractive forces on the order of 1 /spl mu/N/mA at were demonstrated. The magnets produced forces on the order of 3 mN when in contact with ferromagnetic metals (Fe) or similar magnets.

Electrostatic Precipitation of Powdered Activated Carbon and Implications for Secondary Mercury Adsorption within Electrostatic Precipitators (2011)

The injection of powdered sorbents, such as activated carbon, for mercury emissions control at coal-fired power plants has primarily taken place upstream of electrostatic precipitators (ESPs), which far outnumber baghouses in the U.S. Although full-scale sorbent injection tests have demonstrated varying degrees of mercury removal efficiency, the actual behavior of powdered activated carbon (PAC) within an ESP has not been well-established, particularly as this behavior relates to adsorbing gas-phase mercury. In the present experimental investigation, results obtained in a lab-scale ESP indicate that the electrical properties of PAC may cause its collection in a full-scale ESP to be significantly different from that of the native fly ash. There appears to be potential for significant collection of PAC on the discharge electrode wires of an ESP. Because these wires are typically not rapped as frequently as collection electrodes in an ESP, over time, such behavior could potentially create a series of cylindrical PAC structures that contribute non-negligibly to the total mercury removal efficiency within the ESP. To test this potential, the present investigation also presents results from a mass transfer model, in which the PAC-coated discharge electrodes of an ESP are represented as a row of cylindrical mercury sinks, whose radii and ultimate adsorption capacity for mercury vary in time. Results from the mass transfer model show that, after extended periods of PAC injection, the PAC-covered discharge electrodes would continue to adsorb mercury from the flue gas after injection ceases. Over time, the collected PAC becomes saturated, producing a slow rise in the measured mercury concentration at the ESP outlet. This trend agrees with that occasionally observed after full-scale sorbent injection tests and suggests a secondary mechanism for mercury adsorption within ESPs. Such anomalous behavior may require a separate evaluation to assess its impact on ESP operations and maintenance.
Study of the effect of the monomer pressure on the copolymerization of ethylene with 1-hexene (1997)

The effect of ethylene pressure on the copolymerization of ethylene with 1-hexene was studied. The results show an increasing of productivities (g of polymer/nZr h) with pressure. This tendency was not observed for the activity (g of polymer/nZr h bar) that decreases when pressure is raised. When varing the pressure, the characteristics and properties of the formed copolymers are in accordance with the expectation for changes in the monomer concentration; increasing the pressure causes a decrease in comonomer incorporation. At higher ethylene pressure, the polymer is more crystalline due to less incorporation of 1-hexene and the molecular weight is higher. The density of the copolymers also decreases with comonomer incorporation into the copolymer © 1997 John Wiley & Sons, Inc. J Appl Polym Sci 64: 2567–2574, 1997

Ultrafast time-resolved photoluminescence from novel metal–dendrimer nanocomposites (2001)

We report the first results of ultra-fast enhanced light emission from gold– and silver–dendrimer nanocomposites. There is a fast (70 fs) fluorescence decay component associated with the metal nanocomposites. Anisotropy measurements show that this fast component is depolarized. The enhanced emission is suggestively due to local field enhancement in the elongated metal–dendrimer nanoparticles.
Light-Field Camera for Fast Switching of Time-Sequential Two-Dimensional and Three-Dimensional Image Capturing at Video Rate (2019)

In this article, we propose a time-sequential switching light-field (LF) camera for an alternative image capture of the high-resolution two-dimensional (2-D) images and three-dimensional (3-D) LF elemental images as additional functionalities. For image data acquisitions of both the 2-D and 3-D LF imaging of moving objects at a video frame rate (or even higher frame rate up to approximately 1000 f/s), a polarization-dependent-switching microlens array (MLA) is implemented in the LF camera system instead of a conventional passive-type MLA. By controlling the incident polarization conditions using an electrically fast-switching liquid crystal layer, the imaging mode can be time-sequentially switched quite rapidly (switching times of approximately 220 and 290 μs for the mode conversions from the 3-D LF to the 2-D mode, and the reversal mode change, respectively). Using the elemental image sets sampled from the alternating time-sequential imaging results, either the directional-view images or depth-refocused images can be reconstructed and provided at a moving picture frame rate. The depth-refocused images are possible for a wide depth range from 25 to 350 cm. Directional views of 22 × 22 and 9 × 9 in portions can be reconstructed for the single-shot image capture and the time-sequential video-rate image capture, respectively.
Fabrication of Carbohydrate Microarrays on Gold Surfaces:  Direct Attachment of Nonderivatized Oligosaccharides to Hydrazide-Modified Self-Assembled Monolayers (2006)

This paper describes a new and simple microarray platform for presenting multiple nonderivatized oligosaccharides to protein targets, with utility for mapping carbohydrate-protein recognition events. The approach is based on the creation of a hydrazide-derivatized, self-assembled monolayer on a gold surface in a single or two-step procedure, for efficient and selectively oriented anchoring of oligosaccharide probes via their reducing ends, with detection using fluorescence detection of bound proteins. The biggest hurdles in employing gold-based substrate for fluorescence-based microarray detection include fluorescence quenching and nonspecific surface adsorption of proteins. We found that the quenching effect could be minimized by introducing a omega-thiolated fatty acid (C16) self-assembled monolayer between the gold surface and hydrazide groups, followed by detection involving three successive binding protein layers covering the gold surface. In addition, an effective blocking scheme involving poly(ethylene glycol) aldehyde and bovine serum albumin was employed to reduce nonspecific protein adsorption to the chip surface. As proof of principle, we demonstrate here that sulfated oligosaccharide probes from heparin can be effectively and covalently attached without prior derivatization onto the hydrazide-modified, self-assembled monolayer on gold-coated slide surfaces in a microarray format. This platform is used to assess binding of specific heparin-binding protein targets at very high sensitivity, and we also demonstrate that the approach can be extended to nonsulfated sugars. Direct attachment of nonderivatized sugar probes on the chip is advantageous since it avoids the need for laborious prederivatization and cleanup steps. This versatile fluorescence microarray platform provides a facile approach for interrogating multiple carbohydrate-protein interactions in a high-throughput manner and has potential as a common gold surface platform for other diverse interrogations by MALDI-MS, surface plasmon resonance, and quartz crystal microbalances.

Evaluation of mycophenolate mofetil for initial treatment of chronic graft-versus-host disease (2009)

We conducted a double-blind, randomized multicenter trial to determine whether the addition of mycophenolate mofetil (MMF) improves the efficacy of initial systemic treatment of chronic graft-versus-host disease (GVHD). The primary endpoint was resolution of chronic GVHD and withdrawal of all systemic treatment within 2 years, without secondary treatment. Enrollment of 230 patients was planned, providing 90% power to observe a 20% difference in success rates between the 2 arms. The study was closed after 4 years because the interim estimated cumulative incidence of success for the primary endpoint was 23% among 74 patients in the MMF arm and 18% among 77 patients in the control arm, indicating a low probability of positive results for the primary endpoint after completing the study as originally planned. Analysis of secondary endpoints showed no evidence of benefit from adding MMF to the systemic regimen first used for treatment of chronic GVHD. The estimated hazard ratio of death was 1.99 (95% confidence interval, 0.9-4.3) among patients in the MMF arm compared with the control arm. MMF should not be added to the initial systemic treatment regimen for chronic GVHD. This trial was registered at www.clinicaltrials.gov as #NCT00089141 on August 4, 2004.
Logic and Extent of miRNA-Mediated Control of Autoimmune Gene Expression (2009)

Over the past few decades, multiple mechanisms have emerged that operate to prune the lymphocyte repertoire of self-reactive specificities and maintain immunological tolerance. Multiple families of small noncoding RNAs known as microRNAs (miRNAs) target immune transcripts to fine-tune gene expression and turn on negative feedback loops. Both of these actions are crucial to limit co-stimulation, set precise cellular activation thresholds, curtail inflammation, control lymphocyte growth, and maintain regulatory T cell homeostasis and suppressive function. Analysis of predicted miRNA-mediated regulation of 72 lupus susceptibility genes in humans and mice reveals most contain numerous target sites for over 140 miRNAs conserved in mammals. MECP2, ROQUIN/RC3H1, BCL2, BIM, and PTEN contain over 50 miRNA target sites each, highlighting the need to control their final protein products with enormous precision to maintain the balance between immunity and tolerance. Overlap among targets of individual miRNAs is considerable, with each miRNA targeting a median of nine autoimmune genes. Three miRNAs--miR-181, miR-186, and miR-590-3p--together are predicted to target over 50% of all lupus genes. Also, a single miRNA cluster located at 14q32.31 containing 11 miRNAs is predicted to regulate 48 lupus susceptibility genes. Dysregulation of single or a few miRNAs or miRNA clusters can result from genetic variation, hormonal influences, or environmental triggers including EBV infection. In the light of this vast and promiscuous miRNA-mediated regulation of autoimmune genes it is anticipated that changes in miRNA levels or their target sequences will help explain susceptibility to complex autoimmune diseases.
Electroporation of peptides into adherent cells in situ. (1995)

To study the effect of protein interactions in vivo upon cellular functions,such complexes may be disrupted through the introduction of peptides corresponding to the proteins' points of contact. In this communication a simple, rapid and reproducible procedure for peptide introduction into adherent cells by electroporation is described. Cells are grown on electrically conductive, optically transparent indium-tin oxide at the time of pulse delivery. Several electrode and slide configurations, necessary to obtain non-electroporated cells adjacent to the electroporated ones as a control, are outlined. Careful control of electric field strength achieved the introduction of the peptide into essentially 100% of the cells while this treatment caused no detectable disruption of their division cycle.
Improved donor safety in high‐volume apheresis collections (2016)

Limiting apheresis collections to the lesser of 1050 mL or 15% EBV may reduce VVR rates. Further confirmation of this finding by other collection centers is desirable.
Visual Object Networks: Image Generation with Disentangled 3D Representations (2018)

Recent progress in deep generative models has led to tremendous breakthroughs in image generation. While being able to synthesize photorealistic images, existing models lack an understanding of our underlying 3D world. Different from previous works built on 2D datasets and models, we present a new generative model, Visual Object Networks (VONs), synthesizing natural images of objects with a disentangled 3D representation. Inspired by classic graphics rendering pipelines, we unravel the image formation process into three conditionally independent factors---shape, viewpoint, and texture---and present an end-to-end adversarial learning framework that jointly models 3D shape and 2D texture. Our model first learns to synthesize 3D shapes that are indistinguishable from real shapes. It then renders the object's 2.5D sketches (i.e., silhouette and depth map) from its shape under a sampled viewpoint. Finally, it learns to add realistic textures to these 2.5D sketches to generate realistic images. The VON not only generates images that are more realistic than the state-of-the-art 2D image synthesis methods but also enables many 3D operations such as changing the viewpoint of a generated image, shape and texture editing, linear interpolation in texture and shape space, and transferring appearance across different objects and viewpoints.
