Video coding with motion compensation for groups of pictures (2003)

This paper discusses the efficiency of a compression scheme for video sequences that jointly encodes groups of pictures. Our approach, motion-compensated transform coding, applies a KLT to decorrelate a set of motion-compensated pictures for efficient encoding. The theoretical investigation utilizes a signal model for inaccurate motion compensation and provides a performance comparison to motion-compensated prediction. We discuss the influence of motion accuracy, residual noise, and the correlation of displacement errors dependent on the number of coded pictures.
Transactional Lock Elision Meets Combining (2017)

Flat combining (FC) and transactional lock elision (TLE) are two techniques that facilitate efficient multi-thread access to a sequentially implemented data structure protected by a lock. FC allows threads to delegate their operations to another (combiner) thread, and benefit from executing multiple operations by that thread under the lock through combining and elimination optimizations tailored to the specific data structure. TLE employs hardware transactional memory (HTM) that allows multiple threads to apply their operations concurrently as long as they do not conflict. This paper explores how these two radically different techniques can complement one another, and introduces the HTM-assisted Combining Framework (HCF). HCF leverages HTM to allow multiple combiners to run concurrently with each other, as well as with other, non-combiner threads. This makes HCF a good fit for data structures and workloads in which some operations may conflict with each other while others may run concurrently without conflicts. HCF achieves all that with changes to the sequential code similar to those required by TLE and FC, and in particular, without requiring the programmer to reason about concurrency.
Development of birefringence measurement with double rotating polarization components (2003)

A novel birefringence measurement with double rotating polarization elements is proposed. This system includes rotating components of linear polarizer and quarter-wave plate with different rotating speeds. The birefringence is calculated by analyzing the Fourier components for rotation frequency in a detected signal. In this paper, the basic principle and experimental results of the birefringence measurement are described.
T‐cell responses during pig‐to‐primate xenotransplantation (2006)

These findings show that lymphocytes are efficiently stimulated by PAEC antigens and can mediate direct tissue destruction. These studies (1) provide an insight into the potential of cellular-mediated cardiac Xg rejection, (2) show for the first time the induction of cytotoxic pig-specific CD4+CD28- lymphocytes and (3) provide a rational basis for determining different modes of immunosuppression to treat Xg rejection.
The Interferon Receptor (1986)

Early studies on the mode of action of interferons have indicated that a receptor system on the cell surface is involved in its action. The first direct evidence to a high-affinity binding site was found only after pure interferon was available. Two different receptors, one specific for interferons-alpha and beta, and the other for interferon-gamma were recognized. A correlation between affinity to the receptor and specific activity was established. Cross-linked complexes of labeled interferons with their receptors were visualized on gel electrophoresis and even partially purified. Internalization of interferons after binding to the receptor was reported. The role of gangliosides as helpers of interferon binding was recently investigated. Fragments of interferons which still retained binding capacity were described and helped in elucidating the binding site on the interferon molecule.
Carbon Monoxide Gas Dynamic Laser Development (1975)

Abstract : The development of small, electrically excited, supersonic flow carbon monoxide lasers is reported. These lasers utilize aerodynamically stabilized, d.c., glow discharges, which have been successfully operated to pressures of 1.5 atmospheres in CO-He gas mixtures. The following performance levels have been achieved. (1) An 11 gm/sec device, operating at atmospheric discharge pressure, produces 350 watts cw at 11% efficiency, with greater than 60% of its power in the 4.8 to 5.1 micron range, and (2) A 1.5 gm/sec device, operating at discharge pressures in excess of 1.5 atmospheres, produces 17 watts cw at 4% electrical efficiency, with 90% of its power in the 4.8 to 5.1 micron range.
Conjugation of Aztreonam, a Synthetic Monocyclic β-Lactam Antibiotic, to a Siderophore Mimetic Significantly Expands Activity Against Gram-Negative Bacteria (2021)

Monocyclic β-lactams with antibiotic activity were first synthesized more than 40 years ago. Extensive early structure-activity relationship (SAR) studies, especially in the 1980s, emphasized the need for heteroatom activation of monocyclic β-lactams and led to studies of oxamazins, monobactams, monosulfactams, and monocarbams with various side chains and peripheral substitution that revealed potent activity against select strains of Gram-negative bacteria. Aztreonam, still the only clinically used monobactam, has notable activity against many Gram-negative bacteria but limited activity against some of the most problematic multidrug resistant (MDR) strains of <i>Pseudomonas aeruginosa</i> and <i>Acinetobacter baumannii</i>. Herein, we report that extension of the side chain of aztreonam is tolerated and especially that coupling of the side chain free acid with a bis-catechol siderophore mimetic significantly improves activity against the MDR strains of Gram-negative bacteria that are of most significant concern.
Environmentally friendly route for the preparation of solvent resistant polyimide nanofiltration membranes (2010)

Organic Solvent Nanofiltration (OSN) is an emerging membrane separation process with the potential to replace traditional separation techniques. Its advantages include lower energy consumption than alternatives such as distillation, easy up scaling and flexibility. However, manufacturing OSN membranes involves a number of stages contributing towards the discharge of hazardous chemicals as waste. Thus the environmental advantages of employing OSN are to some extent cancelled out by the waste released during OSN membrane production. This paper describes a process for the preparation of polyimide integrally skinned asymmetric OSN membranes with adjustable molecular weight cut off (MWCO). Previously reported methods for producing polyimide based OSN membranes are modified in the presented work without compromising the performance of the membranes. The toxic solvents used to form polymer dope solution, i.e.dimethylformamide (DMF)/1,4-dioxane are replaced by an environmentally friendly dimethyl sulfoxide (DMSO)/acetone solvent system. In order to further diminish the environmental impact, isopropanol was successfully replaced with water in the crosslinking step. Scanning electron microscope images revealed that membranes with spongy matrix without macrovoids were obtained regardless the DMSO/acetone ratio.
Green microwave electronics for the coming era of flexible electronics (2016)

Novel fabrication techniques to manufacture various high performance devices, using both Si and III–V nanomembrane-form materials, that are essential for portable electronics on a biodegradable cellulose nanofibril (CNF) paper are presented. We have introduced a concept of natural biodegradation of the discarded electronic chips that could help reduce the accumulation of the massive amount of persistent electronic waste disposed of daily using CNF that is derived from wood, a natural sustainable resource. CNF paper offers properties as a flexible substrate for high performance electronics. Essential microwave electronic systems, such as Si-based transistor and GaAs-based transistor and diode, were fabricated to demonstrate the feasibility of our novel approach on the CNF substrate. A novel releasable device fabrication technology, along with deterministic assembly printing technique for these high-performance devices, that significantly decreased the amount of GaAs used compared to conventional chip based manufacturing are presented.
Catalytic Conversion of Graphene into Carbon Nanotubes <i>via</i> Gold Nanoclusters at Low Temperatures (2011)

Here, we present the catalytic conversion of graphene layers into carbon nanotubes (CNTs), in the presence of Au nanoparticles (AuNPs) without the need for an additional carbon source. We have demonstrated that this catalytic process takes place at temperatures as low as 500 °C. No other oxide supports decorated with AuNPs were found to grow CNTs at this temperature. These findings highlight the high activity of graphene when used as a support for catalytic reactions.
Combinatorial discovery of a lead-free morphotropic phase boundary in a thin-film piezoelectric perovskite (2008)

We report on the discovery of a lead-free morphotropic phase boundary (MPB) in Sm doped BiFeO3 with a simple perovskite structure using the combinatorial thin film strategy. The boundary is a rhombohedral to pseudo-orthorhombic structural transition which exhibits a ferroelectric to antiferroelectric transition at approximately Bi0.86Sm0.14FeO3 with dielectric constant and out-of-plane piezoelectric coefficient comparable to those of epitaxial (001) oriented PbZr0.52Ti0.48O3 (PZT) thin films at the MPB. The discovered composition may be a strong candidate of a Pb-free piezoelectric replacement of PZT.
Phase-separation immunoassays. (1987)

Solid-phase-based immunoassays have traditionally been plagued by nonspecific binding to the solid phase and by slow reaction kinetics relative to reactants that are free to diffuse in solution. We have developed two novel immunoassays in which the solid phase is generated in situ after the specific binding reaction has occurred, thereby enhancing reaction kinetics and minimizing the opportunities for non-specific binding. In the first system, the capture antibody is conjugated to an organic monomer, polymerization of which to form insoluble polymer particles is initiated by a reaction involving free radicals. The amount of signal-labeled antibody incorporated into the resulting particles is directly proportional to the concentration of antigen. The principle is illustrated for the simultaneous assay of IgG and IgM in a single sample. In the second system, capture antibody is conjugated to a polymer, the solubility of which is a function of temperature. Specific binding is conducted below the critical solution temperature of the polymer, which is then separated from solution by increasing the temperature above the critical temperature. The incorporation of signal-labeled antibody into the precipitated polymer is directly proportional to the concentration of antigen. This principle is illustrated for the assay of hepatitis B surface antigen and Chlamydia trachomatis.
Catalyst modification and process design considerations for the oxidation of low concentrations of hydrogen sulfide in natural gas (1990)

Abstract Low concentrations of hydrogen sulfide (H 2 S) in natural gas can be selectively oxidized over an activated carbon catalyst to elemental sulfur, water and a small fraction of sulfur dioxide (SO 2 ). Efforts to improve catalyst performance and product sulfur quality have been made by a) modification of the catalyst composition b) removal of the heavy hydrocarbons from the feed and c) choice of reaction conditions. The use of a guard bed to absorb heavy hydrocarbons and operation at elevated pressures show positive results. A preliminary flow diagram incorporating these findings has been prepared for a small commercial unit capable of processing sour natural gas containing 1.0% H 2 S.
Optical Wireless Communications (2005)

An optical wireless local area network using line of sight optical links. The base station and terminal stations are provided with optical transceivers which include a transmitter array and detector array. The transmitter array consists of an array of resonant cavity light emitting diodes integrated using flip-chip technology with a CMOS driver circuit. The driver circuit includes constant bias, current peaking and charge extraction. The driver circuitry is compact and can be confined within a region underlying the corresponding light source. The detector array consists of an array of photo diodes, provided with sense circuitry consisting of a pre-amplifier and post-amplifier. The diodes and sense circuitry are also integrated using a flip-chip technique. The light emitter and the detector may include adaptive optical elements to steer and/or focus the light beams.
Integrated link adaptation and power control for wireless IP networks (2002)

In this paper, we prove that the problem of maximizing data throughput by adaptive modulation and power control while meeting packet error requirements is NP-complete. A heuristic algorithm for integrated link adaptation and power control is thus proposed to achieve specified error rates and to improve overall throughput for real-time applications in wireless IP networks. The algorithm divides terminals into groups according to their signal path gains, and periodically adapts transmissions based on the required error rates, actual error statistics and average transmission power of each terminal group. Transmission power is adjusted by an enhanced Kalman-filter method to ensure successful reception. Simulation results reveal that the algorithm consistently delivers the specified error performance, and attempts to maximize network throughput for a wide range of parameter settings.
Isolation and Characterization of a 6/85-like Mycoplasma gallisepticum from Commercial Laying Hens (2003)

Eighty-three-week-old table egg layers with swollen sinuses were presented with a history of increased mortality. Serology revealed positive titers to Mycoplasma gallisepticum (MG). The birds were part of a flock in which some birds had been vaccinated with 6/85 live MG vaccine at 18 wk of age. Tracheal cultures were obtained from both vaccinated and unvaccinated birds within the flock. The cultures were indistinguishable from 6/85 vaccine by both random amplified polymorphic DNA analysis and DNA sequence analysis. Challenge studies were performed to compare the field isolates with 6/85 vaccine and the R strain of MG. The field isolates produced a greater antibody response by serum plate agglutination than did the 6/85 vaccine. The isolates effectively colonized the trachea without increasing the tracheal mucosal thickness; however, they did not extensively colonize the air sacs or cause airsacculitis in the experimental birds.
A universal strategy for preparing protected C-terminal peptides on the solid phase through an intramolecular click chemistry-based handle (2012)

A new universal strategy exploits DKP formation in a dipeptide moiety whose C-terminal residue is blocked by a leaving group. It enables both synthesis of C-terminal protected peptides that are useful for convergent synthesis of large peptides and use of a C-terminal permanent protecting group that can be cleaved by catalytic hydrogenation to release the peptide.
Snapshot hyperspectral imaging: the hyperpixel array camera (2009)

Hyperspectral imaging has important benefits in remote sensing and material identification. This paper describes a class of hyperspectral imaging systems which utilize a novel optical processor that provides video-rate hyperspectral datacubes. These systems have no moving parts and do not operate by scanning in either the spatial or spectral dimension. They are capable of recording a full three-dimensional (two spatial, one spectral) hyperspectral datacube with each video frame, ideal for recording data on transient events, or from unstabilized platforms. We will present the results of laboratory and field-tests for several of these imagers operating in the visible, near-infrared, mid-wavelength infrared (MWIR) and long-wavelength infrared (LWIR) regions.
Fast neutron coded-aperture imaging of special nuclear material configurations (2012)

In the past year, a prototype fast-neutron coded-aperture imager has been developed that has sufficient efficiency and resolution to make the counting of warheads for possible future treaty confirmation scenarios via their fission-neutron emissions practical. The imager is constructed from custom-built pixelated liquid scintillator detectors. The liquid scintillator detectors enable neutron-gamma discrimination via pulse shape, and the pixelated construction enables a sufficient number of pixels for imaging in a compact detector with a manageable number of channels of readout electronics. The imager has been used to image neutron sources at ORNL, special nuclear material (SNM) sources at the Idaho National Laboratory (INL) Zero Power Physics Reactor (ZPPR) facility, and neutron source and shielding configurations at Sandia National Laboratories. This paper reports on the design and construction of the imager, characterization measurements with neutron sources at ORNL, and measurements with SNM at the INL ZPPR facility.
Ferroelectricity in ultrathin perovskite films (2005)

We report studies of ferroelectricity in ultrathin perovskite films with realistic electrodes. The results reveal stable ferroelectric states in thin films less than $10\phantom{\rule{0.3em}{0ex}}\mathrm{\AA{}}$ thick with polarization normal to the surface. Under short-circuit boundary conditions, the screening effect of realistic electrodes and the influence of real metal-oxide interfaces on thin film polarization are investigated. Our studies indicate that metallic screening from the electrodes is affected by the difference in work functions at oxide surfaces. We demonstrate this effect in ferroelectric $\mathrm{Pb}\mathrm{Ti}{\mathrm{O}}_{3}$ and $\mathrm{Ba}\mathrm{Ti}{\mathrm{O}}_{3}$ films.

Pouches for Indeterminate Colitis and Crohn's Disease: Act now, Pay Later? (2011)

Although ileal pouch-anal anastomosis (IPAA) is the surgical standard of care for patients with ulcerative colitis (UC), the role of this procedure in patients with indeterminate colitis (IC) and Crohn's disease (CD) is more controversial. Recent studies have shown no significant adverse surgical outcome of IPAA in IC patients. The outcome of IPAA in CD patients appears to depend on when the diagnosis of CD is established. Although Crohn's colitis patients with small bowel inflammation and/or anal disease should not be offered an IPAA, carefully selected CD patients without small bowel or perianal disease may safely undergo an IPAA. Patients in whom the diagnosis of CD is made on the basis of the resected colon fare well after IPAA. CD that develops months or years after IPAA has an aggressive disease course that appears to respond favorably to biologic therapies such as infliximab.
PiCode: A New Picture-Embedding 2D Barcode (2016)

Nowadays, 2D barcodes have been widely used as an interface to connect potential customers and advertisement contents. However, the appearance of a conventional 2D barcode pattern is often too obtrusive for integrating into an aesthetically designed advertisement. Besides, no human readable information is provided before the barcode is successfully decoded. This paper proposes a new picture-embedding 2D barcode, called PiCode, which mitigates these two limitations by equipping a scannable 2D barcode with a picturesque appearance. PiCode is designed with careful considerations on both the perceptual quality of the embedded image and the decoding robustness of the encoded message. Comparisons with the existing beautified 2D barcodes show that PiCode achieves one of the best perceptual qualities for the embedded image, and maintains a better tradeoff between image quality and decoding robustness in various application conditions. PiCode has been implemented in the MATLAB on a PC and some key building blocks have also been ported to Android and iOS platforms. Its practicality for real-world applications has been successfully demonstrated.
Comparative analysis of <i>Campylobacter lari</i> cytolethal distending toxin (CDT) effect on HeLa cells (2012)

We aimed to clarify if Campylobacter lari exerts a cytolethal distending toxin (CDT) effect on HeLa cells. Campylobacter cell lysates (CCLys) from C. jejuni 81-176 and urease-positive thermophilic Campylobacter (UPTC) CF89-12 and UPTC NCTC12893 isolates were shown to exert a CDT effect on HeLa cells with morphological changes examined by Giemsa staining and microscopy. However, Campylobacter lari JCM2530(T) isolate showed no effect. In addition, Campylobacter cell culture supernatant wash gave low or absent toxic effects with both C. jejuni and C. lari organisms. When western blot analysis was carried out to clarify if there was a CDTB effect in the CCLys and soluble fractions from Campylobacter isolates, which had a CDT effect on HeLa cells or did not have any effect, anti-recombinant CjCDTB antibodies identified an immunoreactively positive signal at around approximately 25 kDa on all the C. lari isolates examined, as well as the C. jejuni 81116 strain. Thus, all the Campylobacter isolates including those without any CDT effect were shown to express CDTB at the translational level.
29.3: A Novel Patterning Method for Full‐Color Organic Light‐Emitting Devices: Laser Induced Thermal Imaging (LITI) (2004)

Abstract We have developed a novel color patterning method for the fabrication of large format full‐color OLEDs. Laser Induced Thermal Imaging (LITI) is a laser addressed high resolution thermal patterning process with unique advantages such as excellent transfer film thickness uniformity, multilayer stack transfer ability, and scalability to large‐size mother glass. LITI patterning of small molecule materials produces OLEDs that are comparable in performance to conventional evaporated devices. Using the technology, we fabricated 2.2″ full color active matrix OLEDs.
