FireCrystal: Understanding interactive behaviors in dynamic web pages (2009)

For developers debugging their own code, augmenting the code of others, or trying to learn the implementation details of interactive behaviors, understanding how web pages work is a fundamental problem. FireCrystal is a new Firefox extension that allows developers to indicate interactive behaviors of interest, and shows the specific code (Javascript, CSS, and HTML) that is responsible for those behaviors. FireCrystal provides an execution timeline that users can scrub back and forth, and the ability to select items of interest in the actual web page UI to see the associated code. FireCrystal may be especially useful for developers who are trying to learn the implementation details of interactive behaviors, so they can reuse these behaviors in their own web site.
An acoustofluidic sputum liquefier (2015)

We demonstrate the first microfluidic-based on-chip liquefaction device for human sputum samples. Our device is based on an acoustofluidic micromixer using oscillating sharp edges. This acoustofluidic sputum liquefier can effectively and uniformly liquefy sputum samples at a throughput of 30 μL min(-1). Cell viability and integrity are maintained during the sputum liquefaction process. Our acoustofluidic sputum liquefier can be conveniently integrated with other microfluidic units to enable automated on-chip sputum processing and analysis.
Eye Pull, Eye Push: Moving Objects between Large Screens and Personal Devices with Gaze and Touch (2013)

Previous work has validated the eyes and mobile input as a viable approach for pointing at, and selecting out of reach objects. This work presents Eye Pull, Eye Push, a novel interaction concept for content transfer between public and personal devices using gaze and touch. We present three techniques that enable this interaction: Eye Cut & Paste, Eye Drag & Drop, and Eye Summon & Cast. We outline and discuss several scenarios in which these techniques can be used. In a user study we found that participants responded well to the visual feedback provided by Eye Drag & Drop during object movement. In contrast, we found that although Eye Summon & Cast significantly improved performance, participants had difficulty coordinating their hands and eyes during interaction.
DENV Inhibits Type I IFN Production in Infected Cells by Cleaving Human STING (2012)

Dengue virus (DENV) is a pathogen with a high impact on human health. It replicates in a wide range of cells involved in the immune response. To efficiently infect humans, DENV must evade or inhibit fundamental elements of the innate immune system, namely the type I interferon response. DENV circumvents the host immune response by expressing proteins that antagonize the cellular innate immunity. We have recently documented the inhibition of type I IFN production by the proteolytic activity of DENV NS2B3 protease complex in human monocyte derived dendritic cells (MDDCs). In the present report we identify the human adaptor molecule STING as a target of the NS2B3 protease complex. We characterize the mechanism of inhibition of type I IFN production in primary human MDDCs by this viral factor. Using different human and mouse primary cells lacking STING, we show enhanced DENV replication. Conversely, mutated versions of STING that cannot be cleaved by the DENV NS2B3 protease induced higher levels of type I IFN after infection with DENV. Additionally, we show that DENV NS2B3 is not able to degrade the mouse version of STING, a phenomenon that severely restricts the replication of DENV in mouse cells, suggesting that STING plays a key role in the inhibition of DENV infection and spread in mice.
Synthesis and Photoluminescent Properties of Size-Controlled Germanium Nanocrystals from Phenyl Trichlorogermane-Derived Polymers (2008)

We report the preparation of luminescent oxide-embedded germanium nanocrystals (Ge-NC/GeO2) by the reductive thermal processing of polymers derived from phenyl trichlorogermane (PTG, C6H5GeCl3). Sol-gel processing of PTG yields air-stable polymers with a Ge:O ratio of 1:1.5, (C6H5GeO1.5)n, that thermally decompose to yield a germanium rich oxide (GRO) network. Thermal disproportionation of the GRO results in nucleation and initial growth of oxide-embedded Ge-NC, and subsequent reaction of the GeO2 matrix with the reducing atmosphere results in additional nanocrystal growth. This synthetic method affords quantitative yields of composite powders in large quantities and allows for Ge-NC size control through variations of the peak thermal processing temperature and reaction time. Freestanding germanium nanocrystals (FS-Ge-NC) are readily liberated from Ge-NC/GeO2 composite powders by straightfoward dissolution of the oxide matrix in warm water. Composites and FS-Ge-NC were characterized using thermogravimetric analysis (TGA), Fourier transform infrared spectroscopy (FTIR), Raman spectroscopy, X-ray powder diffraction (XRD), X-ray photoelectron spectroscopy (XPS), transmission electron microscopy (TEM), selected area electron diffraction (SAED), energy dispersive X-ray spectroscopy (EDX), and photoluminescence (PL) spectroscopy.
Equilibrium Transition Study for a Hybrid MAV (2011)

Wind tunnel testing was performed on a VTOL aircraft in order to characterize longitudinal flight behavior during an equilibrium transition between vertical and horizontal flight modes. Trim values for airspeed, pitch, motor speed and elevator position were determined. Data was collected by independently varying the trim parameters, and stability and control derivatives were identified as functions of the trim pitch angle. A linear fractional representation model was then proposed, along with several methods to improve longitudinal control of the aircraft.
Model-based control of rapid thermal processing for semiconductor wafers (2004)

This work describes the application of model-based control system design techniques to rapid thermal processing (RTP). The work considers all aspects of the distributed temperature control problem from physics-based modeling to implementation of the real-time embedded controller. With its exceptionally stringent performance requirements (low non-uniformity of wafer temperature, high temperature ramp rates), RTP temperature control is a challenging distributed temperature control problem. Additionally, it is an important problem in the semiconductor industry because of the progressively smaller 'thermal budget' resulting from ever decreasing integrated circuit dimensions. Despite the emphasis on faster cold wall, single-wafer processing RTP chambers, the approach described here for solving distributed temperature control problems is equally applicable to slower distributed thermal systems such as, hot-wall batch-processing furnaces. For the physical model, finite volume techniques are used to develop high-fidelity heat transfer models that may be used for both control design and optimal chamber design. Model-order reduction techniques are employed to reduce these models to lower orders for control system design. In particular, principal orthogonal decomposition (POD) techniques have been used to derive low order models. Multivariable techniques such as LQG, H/sub 2// H/sub /spl infin// methods are employed for feedback control design. These methods have been successfully implemented on commercial RTP chambers.
Growth and patterning of GaAs/Ge single crystal layers on Si substrates by molecular beam epitaxy (1984)

Single crystal GaAs layers have been grown on Si substrates with an intermediate Ge layer. Both the Ge and subsequent GaAs are grown in situ by molecular beam epitaxy (MBE). Cross-sectional transmission electron microscopy studies show GaAs surface dislocation densities on the order of 107 cm−2. The quality of the GaAs is indicated by a mobility within 15% of that measured on GaAs/GaAs MBE structures doped at the same level. This material also exhibits a photoluminescence signal with a room-temperature intensity about 50% of GaAs grown on GaAs, and with a similar half-width. In this letter, electron diffraction, optical and electrical data are presented for n-type GaAs/Ge/Si structures. In addition, a selective lift-off technique is demonstrated, with possible applications in the development of monolithic GaAs/Si integrated circuits.
Metallic interfaces in a <mml:math xmlns:mml="http://www.w3.org/1998/Math/MathML"><mml:msub><mml:mrow><mml:mi>CaTiO</mml:mi></mml:mrow><mml:mn>3</mml:mn></mml:msub></mml:math>/<mml:math xmlns:mml="http://www.w3.org/1998/Math/MathML"><mml:msub><mml:mrow><mml:mi>LaTiO</mml:mi></mml:mrow><mml:mn>3</mml:mn></mml:msub></mml:math> superlattice (2020)

Apart from a handful of exceptions, all known complex oxide two-dimensional electron gases (2DEGs) are formed in ${\mathrm{SrTiO}}_{3}$-based heterostructures, and microscopic information about non-${\mathrm{SrTiO}}_{3}$ 2DEGs systems is scarce. Here, we report on the realization of metallic conductance in a ${\mathrm{CaTiO}}_{3}$-based system, ${\mathrm{CaTiO}}_{3}$/${\mathrm{LaTiO}}_{3}$ superlattices, epitaxially grown in a layer-by-layer way on a ${\mathrm{NdGaO}}_{3}$(110) substrate by pulsed laser deposition. The high quality of the crystal and electronic structures is characterized by in situ reflection high-energy electron diffraction, x-ray diffraction, scanning transmission electron microscopy, and x-ray photoemission spectroscopy. Electrical transport confirms the formation of metallic interfaces in the ${\mathrm{CaTiO}}_{3}$/${\mathrm{LaTiO}}_{3}$ superlattice. In addition, Hall measurements reveal that in the ${\mathrm{CaTiO}}_{3}$/${\mathrm{LaTiO}}_{3}$ superlattice the room-temperature carrier mobility is nearly three times higher than that of the ${\mathrm{CaTiO}}_{3}$/${\mathrm{YTiO}}_{3}$ superlattice, implying the importance of ${\mathrm{TiO}}_{6}$ octahedral tilts and rotations on the carrier mobility of a 2DEG. Since doped ${\mathrm{CaTiO}}_{3}$ is an A-site polar metal, our results provide a materials system for designing synthetic two-dimensional polar metals.
Surface modification of polymeric biomaterials by albumin grafting using γ‐irradiation (1994)

Polymeric biomaterial surfaces were modified by albumin grafting to improve their blood compatibility. Albumin molecules were functionalized by introducing double bonds using glycidyl acrylate. The functionalized albumin was covalently attached to various biomaterial surfaces such as polypropylene, polycarbonate, and poly(vinyl chloride) by h-irradiation. Surface-induced platelet adhesion and thrombus formation on the albumin-grafted surfaces was examined using computer-enhanced video microscopy and scanning electron microscopy. The amount of the grafted albumin was dependent on the h-irradiation dose and the concentration of albumin used for adsorption. The grafted albumin molecules remained on the surface even after exposure to blood for prolonged time periods. This approach was used to graft albumin to polymeric materials of an oxygenator. The albumin grafting resulted in a substantial improvement in blood compatibility as compared to control oxygenators. The covalent grafting of functionalized albumin by h-irradiation obviates the need for premodification of chemically inert polymer surfaces. It is useful for albumin grafting to various biomaterial surfaces.
Study of Cardiorespiratory and Sweat Monitoring Wearable Architecture for Coal Mine Workers (2020)

In an industrial environment, there is always a surging demand for a wearable device to cope up with the increasing degree of automation and reduced manual intervention. The requirement of the wearable is related to the employee's health and well-being. Safety remains a prime concern despite other large-scale availability of the personal protective equipment (PPE) and the adoption of strict safety measures. The wearable can be an essential component of the worker's toolkit, as its application is increasingly demanding. We have developed an integrated cardiorespiratory & sweat monitoring wearable and performed extensive experiments in an operational underground mine in different conditions. The appearance of a wearable platform with biochemical analysis, physiological parameters monitoring along with ambient environment sensors has enabled the observation of critical indicators of performance as well as the stress of mineworkers.
Selective cell killing by microparticle absorption of pulsed laser radiation (1999)

The mechanism of interaction between subcellular pigment microparticles and short pulse laser radiation was investigated with nanosecond time-resolved microscopy and fluorescence microscopy. Stroboscopic illumination was used to capture images of transient events induced in cells by laser pulses. Fluorescence microscopy enabled assessment of cell damage using fluorescent probes. Short-lived intracellular cavitation bubbles were directly visualized within nanoseconds after laser irradiation. Microbubble expansion and implosion took place on the timescale of 0.1-1 /spl mu/s and were confined entirely within pigmented cells with remarkable selectivity. Cells containing particles underwent cavitation and rapidly lost viability, while adjacent cells without particles remained viable. Nonpigmented cells can be targeted by labeling them with absorbing particles. Laser-pumped microparticles provide an efficient means of selective cell targeting.
Specific antimicrobial and hemolytic activities of 18-residue peptides derived from the amino terminal region of the toxin pardaxin (1996)

Peptides are part of the host defense system against bacteria and fungi in species right across the evolutionary scale. However, endogenous antibacterial peptides are often composed of 25 residues or more and, therefore, are not ideal for therapeutic use. Hence it is of considerable interest to design and engineer short peptides having antimicrobial activity. Peptides composed of 18 amino acids, derived from the N-terminal region of the 33-residue toxin pardaxin (PX), GFFALIPKIISSPLFKTLLSAVGSALSSSGEQE, were synthesized and examined for biological activities. Peptide corresponding to the 1-18 stretch of PX exhibited antimicrobial activity only against Escherichia coli and not against Gram-positive microorganisms. The peptide also did not possess hemolytic activity. Replacement of P7 by A resulted in a peptide possessing both antibacterial and hemolytic activity. Substitution of both K residues by Q in the 'A' analog resulted in a peptide having only hemolytic activity. Conformational analysis of these peptides and investigation of their model membrane permeabilizing activities indicated that selective activity can be explained by their biophysical properties. Hence, by a rational design approach based on biophysical principles, it should be possible to generate short peptides having specific biological activity.
Low-voltage ionization of air with carbon-based materials (2005)

Polycrystalline diamond and carbon nanotubes (CNTs) exhibit excellent vacuum field emission properties, characterized by low turn-on voltage and high current density. Their atmospheric field emission and ionization capabilities are reported in this paper. Highly graphitic polycrystalline diamond (HGPD) film was grown in a plasma-enhanced chemical vapour deposition process, and its ability to ionize atmospheric air was characterized and compared against CNTs. The HGPD sample was activated by applying a moderate voltage bias (340 V) for an extended period across a 10µm electrode gap. After activation, a turn-on voltage of 20V and a sustainable current of 10µA were observed with the same gap. Results also indicate that field emission helps to create a moderate ionization effect without catastrophic air breakdown. A hydrogen plasma treatment is shown to restore emission current back to or even exceeding the original level, which suggests an important role of surface termination in the electron emission process. CNTs were grown and tested but did not perform as well under similar conditions.
Mithramycin in the Treatment of Systemic Mastocytosis (1975)

A patient had systemic mastocytosis of 16 years' duration, with urticaria pigmentosa, osteopetrosis with severe bone pain, mastocytosis of the bone marrow with myeloid metaplasia, gastrointestinal malabsorption, and Cushingold features associated with prolonged usage of corticosteroids. Treatment with a single dose of mithramycin resulted in an abrupt disappearance of the patient's generalized bone pain, but it had little effect on his histamine release-type symptomatology.
Statistical-Based WCET Estimation and Validation (2009)

In this paper we present a measurement-based approach that produces both a WCET (Worst Case Execution Time) estimate, and a prediction of the probability that a future execution time will exceed our estimate. Our statistical-based approach uses extreme value theory to build a model of the tail behavior of the measured execution time value. We validate our approach using an industrial data set comprised of over 150 sampled components and nearly 200 million sample execution times. Each trace is divided into two segments, with one used to make the WCET estimate, and the second used check our prediction of the fraction of future execution time samples that exceed our WCET estimate. We show that compared to WCET estimates derived from the worst-case observed time, our WCET estimates significantly improve the ability to predict the probability that our WCET estimate is exceeded.
Media Purchasing Guidelines for the School Administrator (1979)

DEVELOPMENT AND EVALUATION OF NANOSCALE SORBENTS FOR MERCURY CAPTURE FROM WARM FUEL GAS (2005)

The Mercury Testing Experimental System available in GTI's Hot Gas Cleanup laboratory was prepared for the project. As part of the shakedown testing, the system was checked for possible gas leaks and fixed. In addition, the mass flow controller was calibrated for diluent N{sub 2} stream. A major part of the shakedown testing was the calibration of the semi-continuous mercury analyzer and the verification of the permeation rate of the mercury permeation tube. It was found that the analyzer's mercury concentration measurements were much lower than expected from the permeation tube rate calculations. Vendors of the analyzer and the permeation tube are contacted to find out the reason for this discrepancy.
A new authentication mechanism and key agreement protocol for SIP using identity-based cryptography (2006)

The Session Initiation Protocol (SIP) protocol is commonly used to establish Voice over IP (VoIP) calls. IETF SIP standards do not specify a secure authentication process thus allowing malicious parties to impersonate other parties or to charge calls to other parties. This paper proposes an extension to the SIP protocol that uses an identity-based authentication mechanism and key agreement protocol. These extensions provide stronger cryptographic assurances for VoIP authentication and enable provably secure key agreement between users. The use of ID based cryptography means that a large Public Key Infrastructure (PKI) is not required thus making this protocol viable for large scale implementation. 1
Glyphosate and Sc-0224 for Bermudagrass (<i>Cynodon</i>Spp.) Cultivar Control (1988)

An undesirable bermudagrass [ Cynodon dacytlon (L.) Pers. # CYNDA] often must be removed before converting to an improved bermudagrass turf or to a different turfgrass species. Because bermudagrass control with glyphosate [ N -(phosphonomethyl)glycine] has been inconsistent, an experiment was initiated to determine the necessary application rates and frequency for glyphosate and SC-0224 (trimethylsulfonium carboxymethylaminomethylphosphonate) to control bermudagrass. Both glyphosate and SC-0224 applied in three applications (May, June, and August) had controlled three bermudagrass hybrids [ Cynodon transvaalensis Burtt-Davy # CYNTR x C. dactylon (L.) Pers. Tifway’, Tifgreen’, and ‘Tifdwarf’] and ‘Ormond’ bermudagrasses when evaluated the next June. None of the cultivars were controlled effectively with either herbicide applied in one (May) or two (May and June) applications regardless of rate. Control with glyphosate and SC-0224 was similar.
Retinal Abnormalities Associated With Anemia (1983)

The incidence of clinically apparent retinal changes in 35 anemic patients and 35 age- and sex-matched control subjects was studied. Retinal photographs of all subjects were obtained. From these, all vascular and extravascular retinal lesions were noted. No retinal abnormalities were observed in the control subjects. Seven (20%) of the anemic patients exhibited extravascular lesions. There was no relationship detected between the occurrence of these changes and the severity or the cause of the anemia. Employing the assumption that true venous length for a given net distance traveled correlates with the degree of venous tortuosity, venous length over a standard radial distance from the optic disc was assessed with a curvometer. A significant negative correlation was determined between venous length and the level of hematocrit, thereby implying that retinal venous tortuosity is directly related to severity of anemia.
Research Expenditures and the Discovery of New Drugs (1987)

This paper examines technical change in the ethical pharmaceutical industry. A Poisson specification is used to estimate a productivity relationship between research expenditures and drug discoveries, thus taking into account the integer nature of the data. The result s of estimations using panel data indicate that there is a positive c orrelation between a firm's research and development intensity and it s probability of discovering a new drug. Firm size, however, does not significantly affect the marginal productivity of research expenditu res. Finally, the estimates show that an increase in regulatory strin gency decreases the expected number of new drug discoveries. Copyright 1987 by Blackwell Publishing Ltd.

Medical Image Processing On An Enhanced Workstation (1988)

The TAAC-1 Application Accelerator is a specialized processor with an embedded full color display subsystem that is installed in a Sun workstation. The flexibility, performance, and graphics capability of this device make it well suited for medical imaging applications. The architecture of the TAAC-1, software tools, and results of 2D and 3D medical image processing and display applications are described.
Relaxometric Studies of γ-Fe<sub>2</sub>O<sub>3</sub>@SiO<sub>2</sub>Core Shell Nanoparticles: When the Coating Matters (2011)

Iron oxide nanoparticles with a constant superparamagnetic core coated with a silica shell with a thickness ranging from 0.6 to 71 nm were prepared by a fast and facile soft chemistry approach. The increase of the coating thickness of the γ-Fe2O3@SiO2 nanoparticles causes a significant decrease of the r1 and r2 relaxivities of their aqueous suspensions. The sizes of the nanoparticles obtained by relaxometry are significantly lower than those measured by electron microscopy. Their magnetizations measured by relaxometry also decrease relative to the values obtained by magnetometry, which correspond to the core. However, this “magnetic dilution” is smaller than expected if the entire silica shell was water impermeable. Both results indicate that a significant part of the silica coating is permeable to water. The adequate silica shell thickness may, thus, be tuned to allow for both a sufficiently high response as contrast agent and an adequate grafting of targeted biomolecules.
