Flavor: A Language for Media Representation (2003)

Flavor (Formal Language for Audio-Visual Object Representation) has been created as a language for describing coded multimedia bitstreams in a formal way so that the code for reading and writing bitstreams can be automatically generated. It is an extension of C++ and Java, in which the typing system incorporates bitstream representation semantics. This allows describing in a single place both the in-memory representation of data as well as their bitstream-level (compressed) representation. Flavor also comes with a translator that automatically generates standard C++ or Java code from the Flavor source code so that direct access to compressed multimedia information by application developers can be achieved with essentially zero programming. Flavor has gone through many enhancements and this paper fully describes the latest version of the language and the translator. The software has been made into an open source project as of Version 4.1, and the latest downloadable Flavor package is available at http://flavor.sourceforge.net.
Surface-acoustic-wave-controlled photodetectors (2004)

Nitride semiconductor devices have recently been developed for a number of electronic and optoelectronic applications, including amplifiers, light emitters and several kinds of sensors. In particular, ultraviolet detectors with a tailored spectral response can be achieved due to the direct wide bandgap of AlGaN alloys; on the other side, acoustic wave devices take advantage of the piezoelectric and elastic properties. In this work, we will describe the fabrication and characterization of a novel kind of optical detector, based on the interaction of surface acoustic waves and photocarriers. The response, which is linear with the incident optical power, can be controlled either by modifying the input power of the RF signal which creates the acoustic wave, or by tuning its frequency, in the latter case with a very high sensitivity. Several applications can be envisaged as a result of this synergy, such as imaging displays and electro-optical modulators.

Response of a tubular heterogeneous catalytic reactor to a step increase in flow rate (1968)

Abstract The vapor phase dehydration of ethanol to diethyl ether, as catalyzed by ion exchange resin, has been studied experimentally and theoretically for the transient state period following a step increase in flow rate. A mathematical model is developed to account quantitatively for the effects of adsorption and surface reaction on the product distribution in the effluent of a tubular reactor. The solution of the model is in good agreement with the experimentally observed behavior.
A Parallelizing Matlab Compiler Framework and Run Time for Heterogeneous Systems (2015)

Compute-intensive applications incorporate ever increasing data processing requirements on hardware systems. Many of these applications have only recently become feasible thanks to the increasing computing power of modern processors. The Matlab language is uniquely situated to support the description of these compute-intensive scientific applications, and consequently has been continuously improved to provide increasing computational support in the form of multithreading for CPUs and utilizing accelerators such as GPUs and FPGAs. Moreover, to take advantage of the computational support in these heterogeneous systems from the problem domain to the computer architecture necessitates a wide breadth of knowledge and understanding. In this work, we present a framework for the development of compute-intensive scientific applications in Matlab using heterogeneous processor systems. We investigate systems containing CPUs, GPUs, and FPGAs. We leverage the capabilities of Matlab and supplement them by automating the mapping, scheduling, and parallel code generation. Our experimental results on a set of benchmarks achieved from 20x to 60x speedups compared to the standard Matlab CPU environment with minimal effort required on the part of the user.

Efficient hybrid and screened hybrid density functional calculations of carbon and silicon nanostructures electronic properties (2018)

Hybrid functionals combine Density Functional Theory (DFT) with a fraction of Fock exchange. Screened hybrid functionals use a screened Fock exchange instead. In recent years, those methods became more popular as they yield results that are in better agreement with experiment for various physical properties. However, the calculation of Fock exchange can be computationally intensive for large systems. In this paper, we demonstrate the use of an efficient real-space approach that is based on projection schemes and an FFT based Poisson solver, for large atomistic systems. We apply this approach for silicon quantum dots and graphene nanoribbons and show the size dependence of physical properties such as the band gap and ionization potential. Finally, we show how those calculations can be further accelerated through the use of Graphical Processing Units (GPUs).

Leaf transformation for efficient random integration and targeted genome modification in maize and sorghum (2023)

Transformation in grass species has traditionally relied on immature embryos and has therefore been limited to a few major Poaceae crops. Other transformation explants, including leaf tissue, have been explored but with low success rates, which is one of the major factors hindering the broad application of genome editing for crop improvement. Recently, leaf transformation using morphogenic genes Wuschel2 (Wus2) and Babyboom (Bbm) has been successfully used for Cas9-mediated mutagenesis, but complex genome editing applications, requiring large numbers of regenerated plants to be screened, remain elusive. Here we demonstrate that enhanced Wus2/Bbm expression substantially improves leaf transformation in maize and sorghum, allowing the recovery of plants with Cas9-mediated gene dropouts and targeted gene insertion. Moreover, using a maize-optimized Wus2/Bbm construct, embryogenic callus and regenerated plantlets were successfully produced in eight species spanning four grass subfamilies, suggesting that this may lead to a universal family-wide method for transformation and genome editing across the Poaceae.
Flexible Glassy Carbon Multielectrode Array for In Vivo Multisite Detection of Tonic and Phasic Dopamine Concentrations (2022)

Dopamine (DA) plays a central role in the modulation of various physiological brain functions, including learning, motivation, reward, and movement control. The DA dynamic occurs over multiple timescales, including fast phasic release, as a result of neuronal firing and slow tonic release, which regulates the phasic firing. Real-time measurements of tonic and phasic DA concentrations in the living brain can shed light on the mechanism of DA dynamics underlying behavioral and psychiatric disorders and on the action of pharmacological treatments targeting DA. Current state-of-the-art <i>in vivo</i> DA detection technologies are limited in either spatial or temporal resolution, channel count, longitudinal stability, and ability to measure both phasic and tonic dynamics. We present here an implantable glassy carbon (GC) multielectrode array on a SU-8 flexible substrate for integrated multichannel phasic and tonic measurements of DA concentrations. The GC MEA demonstrated <i>in vivo</i> multichannel fast-scan cyclic voltammetry (FSCV) detection of electrically stimulated phasic DA release simultaneously at different locations of the mouse dorsal striatum. Tonic DA measurement was enabled by coating GC electrodes with poly(3,4-ethylenedioxythiophene)/carbon nanotube (PEDOT/CNT) and using optimized square-wave voltammetry (SWV). Implanted PEDOT/CNT-coated MEAs achieved stable detection of tonic DA concentrations for up to 3 weeks in the mouse dorsal striatum. This is the first demonstration of implantable flexible MEA capable of multisite electrochemical sensing of both tonic and phasic DA dynamics <i>in vivo</i> with chronic stability.
Cytotoxic activity of T cells and non-T cells from diclofenac-immunized mice against cultured syngeneic hepatocytes exposed to diclofenac (1995)

To evaluate whether hepatocellular protein adducts of the nonsteroidal antiinflammatory drug diclofenac could elicit a specific cell-mediated or antibody-dependent immune response that eventually results in liver cell destruction, we developed a murine ex vivo/in vitro mixed lymphocyte hepatocyte culture (MLHC) model. C57BL/6 mice were immunized either with diclofenac conjugated to keyhole limpet hemocyanin (KLH) or with KLH alone. Splenocytes from mice exhibiting hgih antidiclofenac antibody titers were isolated and co-cultured at an effector/target cell ratio of 100:1 with syngeneic murine hepatocytes preexposed to diclofenac. By 48 and 72 hours, extracellular alanine transaminase (ALT) activity had increased 6.4- and 7.6-fold, respectively, versus the 24-hour value. In contrast, there was no significant cytotoxic response after either drug treatment alone or immunization alone. Furthermore, those cellular populations capable of inducing ALT release also showed lymphocyte stimulation as determined by interleukin-2 (IL-2) receptor expression and lymphocyte proliferation analysis. The extent of cell injury was highest in the presence of lymphocytes highly enriched in T cells and was reduced by 40% in the presence of anti-MHC I antibodies. Similarly, albeit to a lesser extent, non-T cell-enriched lymphocyte fractions also induced hepatocyte injury. The addition of co-culture supernatants to hepatocytes had no effect, thus ruling out the possibility that soluble factors alone mediated the cell injury. However, supernatants from diclofenac-stimulated lymphocytes, combined with nonstimulated splenocytes, triggered an immediate (< 1 hour) cytotoxic response, suggesting antibody-dependent cell-mediated mechanisms of target cell injury. These results indicate that diclofenac-treated hepatocytes carried antigenic determinants that were recognized by T cells and non-T cells derived from diclofenac/KLH-immunized mice, resulting in cell-mediated destruction of the target hepatocytes.
BIOLOGICAL STUDIES ON FORMYCIN AND FORMYCIN B (1968)

The antitumor effect, distribution among various organs and toxicity of formycin and formycin B are studied. Formycin inhibits of Ehrlich carcinoma and L-1210, with stronger activity on the solid form than on the ascites form. Formycin B shows no inhibition of Ehrlich carcinoma or L-1210. The distribution among various organs of mice was examined after subcutaneous injection with 3H-formycin or 3H-formycin B. On the basis of radioactivity, formycin shows high concentrations in spleen and kidney, and formycin B is found in peritoneum, urinary bladder, kidney and spleen. By testing the effect on X. oryzae, low antibacterial activity was shown in various organs. When the lethal dose of formycin was injected in dogs, liver damage was found. Formycin B gives a marked reduction in white blood cells, though this reduction is recovered.
Enhancing storage system availability on multi-core architectures with recovery-conscious scheduling (2008)

In this paper we develop a recovery conscious framework for multi-core architectures and a suite of techniques for improving the resiliency and recovery efficiency of highly concurrent embedded storage software systems. Our techniques aim at providing continuous availability and performance during recovery while minimizing the time to recovery and the need for rearchitecting the system (legacy code). The main contributions of our recovery conscious framework include (1) a task-level recovery model, which consists of mechanisms for classifying storage tasks into recovery groups and dividing the overall system resources into recovery-oriented resource pools, and (2) the development of recovery-conscious scheduling, which enforces some serializability of failuredependent tasks in order to reduce the ripple effect of software failure and improve the availability of the system. We present three alternative recoveryconscious scheduling algorithms; each represents one way to trade-off between recovery time and system performance. We have implemented and evaluated these recovery-conscious scheduling algorithms on a real industry-standard storage system. Our experimental evaluation results show that the proposed recovery conscious scheduling algorithms are nonintrusive and can significantly improve (throughput by 16.3 % and response time by 22.9%) the performance of the system during failure recovery. 1
Characterization of pyranose oxidase variants for bioelectrocatalytic applications (2019)

Pyranose oxidase (POx) catalyzes the oxidation of d-glucose to 2-ketoglucose with concurrent reduction of oxygen to H<sub>2</sub>O<sub>2</sub>. POx from Trametes ochracea (ToPOx) is known to react with alternative electron acceptors including 1,4-benzoquinone (1,4-BQ), 2,6-dichlorophenol indophenol (DCPIP), and the ferrocenium ion. In this study, enzyme variants with improved electron acceptor turnover and reduced oxygen turnover were characterized as potential anode biocatalysts. Pre-steady-state kinetics of the oxidative half-reaction of ToPOx variants T166R, Q448H, L545C, and L547R with these alternative electron acceptors were evaluated using stopped-flow spectrophotometry. Higher kinetic constants were observed as compared to the wild-type ToPOx for some of the variants. Subsequently, the variants were immobilized on glassy carbon electrodes. Cyclic voltammetry measurements were performed to measure the electrochemical responses of these variants with glucose as substrate in the presence of 1,4-BQ, DCPIP, or ferrocene methanol as redox mediators. High catalytic efficiencies (I<sub>max</sub><sup>app</sup>/K<sub>M</sub><sup>app</sup>) compared to the wild-type POx proved the potential of these variants for future bioelectrocatalytic applications, in biosensors or biofuel cells. Among the variants, L545C showed the most desirable properties as determined kinetically and electrochemically.
Scaling and dimensional methods to incorporate knock and flammability limits in models of high-efficiency gasoline and ethanol engines (2014)

Recent work has shown the utility of using simplified models with prescribed burn rates to assess the potential of advanced combustion strategies to increase engine efficiency. However, this approach can be improved by incorporating knock and flammability limits. This work incorporates such limits using a combination of simplified conceptual models that are based on theoretical understanding of knock and flame phenomenon and calibration with experimental results. Using this method, the ideal (unconstrained) and feasible (constrained by knock and flammability) potential of a high efficiency gasoline and E85 engine are compared against a baseline naturally aspirated gasoline engine. Turbocharging, dilution with EGR, and higher compression ratios are used to increase the efficiency potential of the high efficiency gasoline and E85 engines. Results demonstrate the benefit of using this simplified approach in modeling high efficiency engines: the high efficiency gasoline engine is most limited by knock while the E85 engine is limited much less; also increased EGR can be used for the E85 engine due to the higher flame speeds of ethanol. Fuel economy maps are created for each engine/fuel strategy and evaluated in a vehicle model to obtain fuel economy results. Results comparing feasible engines show that peak brake thermal efficiency (BTE) is increased by 11.4% for the high efficiency gasoline engine and 17.8% for the E85 engine, as compared to the baseline gasoline engine. Projected vehicle fuel economy (energy equivalent) improvements are 30.1% for the high efficiency gasoline, and 40.9% for the E85 engine relative to baseline.
The novel plasma etching process for defect reduction in photomask fabrication (2009)

As the device design rule shrinks, photomask manufacturers need to have advanced defect controllability during the Cr and MoSi etch in the process of phase shift mask(PSM). In order to decrease the number of defects, which may be originated from the mechanical transferring, plasma ignition and cross-contamination of resist stripping or cleaning process, a novel plasma etching process was developed in a commercial photomask etcher. In this process named as the "In-situ. etching", Cr and Mosi is etched stepwise in a chamber. The In-situ. etching processes produce better defect level than that of the conventional process without deteriorating other mask quality such as CD performance, profile and process reproducibility. Particle generated by plasma ignition in in-situ. etching lead to defect which is an obstacle in Cr etch. Because plasma is stable from Cr etch to Mosi etch, no defect is added in Mosi etch. Furthermore quantitative analysis of by-products deposited and eroded by the chamber position shows that by-products are comprised of Al, chlorine, carbon. These byproducts can be removed by fluorine-containing plasma.
Influence of Reduction Treatment on CO Sensing Properties of SnO2-based Gas Sensor (2006)

Response of SnO2-based sensors to CO under extreme conditions was investigated. It was found that Pd and V2O5-loaded SnO2 device (thick film), after a reduction treatment in CO flow, showed reverse response to dilute CO (increase in resistance) under particular operating conditions, i.e., lower temperature below 325°C, low humidity less than 100 Pa water vapor pressure. The reverse response tended to be more conspicuous as the CO concentration decreased and the coexistent O2 partial pressure increased. Similar reduction-induced reverse response to CO was also observed with Pd-loaded SnO2 device. XPS analysis suggested that the reverse response should be related with the oxidation state of SnO2.
Cutaneous T-cell lymphoma: neoplasm of T cells with helper activity (1979)

Abstract Neoplastic lymphocytes from 3 patients with aleukemic cutaneous T-cell lymphoma were studied to determine if their neoplastic T cells had helper activity, i.e., ability to promote immunoglobulin synthesis by normal human B cells. Homogeneous populations of neoplastic T cells were isolated from involved lymph nodes and in two of three instances were shown to be of monoclonal origin by karyotypic analysis. Mononuclear leukocytes from control peripheral blood were separated into T- and B-cell-enriched fractions by E-rosette formation and subsequent Ficoll-Hypaque flotation. Pokeweed-mitogen-stimulated normal and malignant T cells were co-cultured with normal B cells. Cytocentrifuged cell prepa rations were stained with fluorescein-conjugated goat antihuman immunoglobulin to quantitate immunoglobulin-producing B cells. Addition of control T-cell fractions to control B-cell fractions increased the number of labeled cells from 8 to 34. Neoplastic T cells increased the numbers of normal B cells containing cytoplasmic immunoglobulin to a mean of 125, demonstrating exceptional helper activity. These results support a relationship between the Sezary syndrome, previously demonstrated to be a leukemia of helper T cells, and aleukemic cutaneous T-cell lymphoma and suggest that malignant helper T cells have a distinct affinity for the skin.
Suppression Subtractive Hybridization (2004)

Suppression subtractive hybridization (SSH) is a widely used method for separating DNA molecules that distinguish two closely related DNA samples. Two of the main SSH applications are cDNA subtraction and genomic DNA subtraction. In fact, SSH is one of the most powerful and popular methods for generating subtracted cDNA or genomic DNA libraries. The SSH method is based on a suppression PCR effect and combines normalization and subtraction in a single procedure. The normalization step equalizes the abundance of DNA fragments within the target population, and the subtraction step excludes sequences that are common to the populations being compared. This dramatically increases the probability of obtaining low-abundance differentially expressed cDNA or genomic DNA fragments, and simplifies analysis of the subtracted library. In our hands, the SSH technique has enriched over 1000-fold for rare sequences in a single round of subtractive hybridization.
