A DASH-based Mulsemedia Adaptive Delivery Solution (2018)

The Dynamic Adaptive Streaming over HTTP (DASH) is a standard designed for adaptive multimedia delivery. This paper describes an adaptive multimedia and mulsemedia delivery system which employs an extension of DASH to support multiple sensorial media. Testing using a real-life test-bed shows how user satisfaction increases when employing the proposed solution which exposes users to multi-sensorial content. The motivation behind this work is the creation the first solution for remote adaptive multi-sensory media (mulsemedia) content delivery in order to enhance user satisfaction and increase their quality of experience. A DASH-based mulsemedia delivery system (DASH-MS) was built and tested. This work focuses on a fundamental issue for remote multi-sensory media systems: synchronization and shows how the proposed DASH-MS addresses it. Results of real life subjective testing indicate that the average levels of user satisfaction when exposed to content with the mulsemedia effects are better or at least equal to those when no such effects were included. Additionally, the highest value of the level of satisfaction corresponds to the case when these effects were correctly synchronized. Finally, users seem to have preferred effects in advance than late effects.
Impact of Renal Function on the Pharmacokinetics and Safety of Ceftolozane-Tazobactam (2014)

Ceftolozane-tazobactam is a novel antipseudomonal cephalosporin with a β-lactamase inhibitor. We investigated the pharmacokinetics (PK) and safety of ceftolozane-tazobactam in subjects with various degrees of renal function. In two phase I, open-label studies, a single dose of ceftolozane-tazobactam was administered as a 1-h intravenous infusion to 24 subjects with normal, mild, or moderate renal impairment (1,000/500 mg) and six subjects with severe renal impairment (500/250 mg). Six subjects with end-stage renal disease (ESRD) received two doses of ceftolozane-tazobactam (500/250 mg each), pre- and posthemodialysis (post-HD). PK parameters were determined by noncompartmental methods. Plasma exposure to ceftolozane-tazobactam increased as renal function declined with only slightly increased exposures in subjects with mild renal impairment; the median area under the concentration-time curve from time zero to infinity (AUC0-∞) for ceftolozane and tazobactam increased 1.4- and 1.2-fold, respectively. In subjects with moderate renal impairment, the AUC0-∞ increased 2.5- and 2.2-fold for ceftolozane and tazobactam, respectively. In subjects with severe renal impairment, the dose-normalized median AUC0-∞ for ceftolozane and tazobactam increased 4.4- and 3.8-fold, respectively. In ESRD subjects, ceftolozane and tazobactam concentrations declined rapidly following the start of HD, with approximately 66 and 56% reductions in overall exposure based on the AUC0-∞ before and after dialysis. Slight increases in exposure with mild renal impairment do not warrant a dose adjustment; however, subjects with moderate or severe renal impairment and those on HD require a decrease in the dose, a change in the frequency of administration, or both to achieve exposures within the established safety and efficacy margins of ceftolozane-tazobactam. Ceftolozane-tazobactam was well tolerated by all renal impairment groups.
TactileVR (2016)

We present TactileVR, an immersive presence and tactile feedback into virtual reality. Our system allows users free to move around and interact with physical objects and toys, which co-exist in the virtual world. By integrating tracking information from the space as well as head, hands and feet of the user, we represent this information as virtual proxies in the 3D environment. Each object has a unique appearance and behavior e.g. in an electric circuits lab toy blocks serve as switches, batteries and light bulbs. By tracking and integrating toys and other everyday objects into VR, we are able to create educational and recreational experiences for children, an environment in which they can play and learn more autonomously.
Correlative light and electron microscopy using cathodoluminescence from nanoparticles with distinguishable colours (2012)

Correlative light and electron microscopy promises to combine molecular specificity with nanoscale imaging resolution. However, there are substantial technical challenges including reliable co-registration of optical and electron images, and rapid optical signal degradation under electron beam irradiation. Here, we introduce a new approach to solve these problems: imaging of stable optical cathodoluminescence emitted in a scanning electron microscope by nanoparticles with controllable surface chemistry. We demonstrate well-correlated cathodoluminescence and secondary electron images using three species of semiconductor nanoparticles that contain defects providing stable, spectrally-distinguishable cathodoluminescence. We also demonstrate reliable surface functionalization of the particles. The results pave the way for the use of such nanoparticles for targeted labeling of surfaces to provide nanoscale mapping of molecular composition, indicated by cathodoluminescence colour, simultaneously acquired with structural electron images in a single instrument.
Aero-Performance Efficient Noise Suppression of a Supersonic Model Twin Jet Nacelle (2009)

This paper summarizes on-going experimental research associated with efforts to achieve aero-performance efficient noise reduction of supersonic jet mixing and shock noise for military style supersonic nozzle exhausts. The baseline supersonic nozzle under investigation is one that is designed with a sharp throat radius of curvature and conical convergent and divergent sections with flat seals. Relevant baseline geometries are defined by the supersonic nozzle exhaust ducts on the F101, F110, F414, and F119 engines. Acoustic suppression technology being investigated utilizes corrugated surface topology for the divergent section of a supersonic nozzle, divergent sections with bevelled exhaust, and high pressure water drop injection from the nozzle nacelle trailing edge. Acoustic measurements were acquired for a small scale model, nominally 10 % scale, supersonic nozzle with baseline and suppressed configurations. These nozzles have a nominal exhaust diameter of 5 cm. The suppression concepts are all aero-performance efficient designs that achieve substantial jet mixing noise reduction and elimination of shock generated noise. In the current round of testing, a twin jet nozzle nacelle was designed and fabricated. The twin jet model scale experimental measurements have indicated that corrugated divergent surface topology can suppress mixing noise by 4 dB relative to the baseline and completely eliminate shock generated noise. The reduction in jet mixing noise improves to 5.5 to 6 dB when bypass flow is ported through the interior of the corrugated seal.
Distributed compression of zerotrees of wavelet coefficients (2011)

A distributed coding algorithm is presented for compression of wavelet-transformed data. Data structures based on zerotrees are exploited for efficient compression of the significance map of wavelet coefficients. The coefficients are scanned in two stages, with a significance pass and refinement pass, similar to the SPIHT algorithm. The bits resulting from these passes are Slepian-Wolf coded using an LDPC syndrome code selected from a bank of available codes. A key realization is that, for each bitplane of the wavelet coefficients, the significance pass of the source data can be synchronized with that of the side information. This allows distributed compression of the significance pass. This is substantially different from previous mixed approaches in which the refinement pass was Slepian-Wolf coded, but the significance pass was coded independently. Rate-distortion results are presented for images from the ALOS AVNIR-2 multispectral dataset and compared against those obtained with SPIHT and JPEG2000.

Novel Cell Culture Model Using Pure Hydrostatic Pressure and a Semipermeable Membrane Pouch (2010)

Cell constructs and culture methods are essential tools in tissue engineering. The cell construct should be equivalent to the native cartilage it is intended to replace. Thus, three-dimensional cell constructs are usually composed of a high density of cells and dense extracellular matrix. However, dense constructs suffer from a lack of passive nutrient supply, gas exchange, and removal of degraded debris. We have developed a novel hydrostatic pressure/perfusion culture system that improves the quality of neo-tissues, providing an automated and affordable system for clinical applications. We have also developed a semipermeable membrane pouch that contains a fragile amorphous cell carrier. Although amorphous material is difficult to handle, it is a useful medium in which to deliver cells to the desired site via injection. We evaluated phenotypes of bovine articular chondrocytes embedded in a collagen type I gel enclosed within membrane pouches permeable to molecules of various sizes. Constant or cyclic hydrostatic pressure was externally applied to the medium phase with a new culture system. Accumulation of cartilage specific matrix was promoted with a 500-kDa cutoff membrane pouch and cyclic hydrostatic pressure at 0.5 MPa, 0.5 Hz. This new method will be useful in the delivery of engineered cells to a desired tissue in regenerative medicine.
Advanced material separation technique based on dual energy CT scanning (2009)

We propose a method for material separation using dual energy data. Our method is suitable to separation of three or more materials. In this work we describe our method and show results of numerical simulation and with real dual-energy data of a head phantom. The proposed method of constructing the material separation map consists of the following steps: Data-domain dual energy decomposition - Vector plot - Density plot - Clustering - Color assignment. Density plots are introduced to allow automatic cluster separation. We use special image processing methods, including Gaussian decomposition, to improve the accuracy of material separation. We also propose using the HSL color model for better visualization and to bring a new dimension in material separation display. We study applications of bone removal and virtual contrast removal. Evaluation shows improved accuracy compared to standard methods.
High gain short length phosphate glass erbium-doped fiber amplifier material (2002)

An internal gain of 10 dB (975 nm pumping) has been demonstrated from a 2.2 cm long section of experimental fiber manufactured from Kigre's "MM-2" Er,Yb:phosphate laser glass. As much as 26 dB (1480 nm pumping) of gain Was produced from this same experimental fiber with an 8.8 cm length. Images of the 1.54 /spl mu/m mode field containment for this fiber indicate a perfect match to standard communications transmission fiber.
Thermally Cleavable Surfactants Based on Furan−Maleimide Diels−Alder Adducts (2005)

Two new surfactant molecules are reported that contain thermally labile Diels-Alder adducts connecting the hydrophilic and hydrophobic sections of each molecule. The two surfactants possess identical hydrophobic dodecyl tail segments but have phenol and carboxylic acid hydrophilic headgroups, respectively. Deprotonation with potassium hydroxide affords the formation of water-soluble surfactants. Room temperature aqueous solutions of both surfactants exhibit classical surface-active agent behavior similar to common analagous alkylaryl surfactant molecules. Critical micelle concentrations have been determined for each surfactant through dynamic surface tension and dye solubilization techniques. Small-angle neutron scattering measurements of the aqueous surfactant solutions indicate the presence of spherical micelles with radii of 16.5 angstroms for the carboxylate and 18.8 angstroms for the phenolate. When these surfactants are exposed to elevated temperatures (>50 degrees C), the retro Diels-Alder reaction occurs, yielding hydrophilic and hydrophobic fragments. Aqueous solutions of each surfactant subsequently exhibit a loss of all surface-active behavior and the micellar aggregates are no longer detectable.
Controlled-Release Personal Use Arthropod Repellent Formulation. Phase 2 (1986)

Abstract : An improved controlled-release arthropod repellent formulation for topical application to a person's exposed skin areas that provides extended protection against biting arthropods, which is safe and agreeable to use, which is more compatible with other current and projected military materials and systems than the Army's current 75% N, N-diethyl-m-toluamide (DEET) in alcohol formulation and which compiles with the registration requirements of the Environmental Protection Agency (EPA) has been developed. The Phase I formulation containing 30% DEET and an acrylate polymer served as the starting point for the refinement and development in Phase II. The final Phase II submission contained 35% DEET and the acrylate polymer. This formulation provided 95% repellency against Aedes aegypti mosquitoes for 14-15 hours, 10-11 hours and 14015 hours when evaluated in the constant high humidity, the variable high humidity and the basic hot climatic conditions using a modified standard mosquito repellency test method (ASTM:E951-83).

GeoSim: Photorealistic Image Simulation with Geometry-Aware Composition. (2021)

Scalable sensor simulation is an important yet challenging open problem for safety-critical domains such as self-driving. Current work in image simulation either fail to be photorealistic or do not model the 3D environment and the dynamic objects within, losing high-level control and physical realism. In this paper, we present GeoSim, a geometry-aware image composition process that synthesizes novel urban driving scenes by augmenting existing images with dynamic objects extracted from other scenes and rendered at novel poses. Towards this goal, we first build a diverse bank of 3D objects with both realistic geometry and appearance from sensor data. During simulation, we perform a novel geometry-aware simulation-by-composition procedure which 1) proposes plausible and realistic object placements into a given scene, 2) renders novel views of dynamic objects from the asset bank, and 3) composes and blends the rendered image segments. The resulting synthetic images are photorealistic, traffic-aware, and geometrically consistent, allowing image simulation to scale to complex use cases. We demonstrate two such important applications: long-range realistic video simulation across multiple camera sensors, and synthetic data generation for data augmentation on downstream segmentation tasks.
A Passive RFID Temperature Sensing Antenna With Liquid Crystal Elastomer Switching (2020)

An autonomous and continuously operating Radio Frequency Identification (RFID) temperature sensor is designed, manufactured, and tested. This sensor is battery-free and can detect temperature threshold crossings for multiple (room-to-cold and cold-to-room) temperature cycles, respectively. The proposed sensor conveys temperature threshold crossings through the controlled switching of its operating frequency within the 902-928 MHz Ultra High Frequency (UHF) RFID band. For the first time, shape morphing cold-temperature reactive Liquid Crystal Elastomers (LCEs), which provide reversible actuation, are utilized. The proposed sensor design consists of a patch antenna with a customized slot. A passive mechanical switch is connected across this slot and provides the frequency switching as it is activated and deactivated. The integration of this switch with the antenna is achieved using a co-simulation method. Furthermore, the cold-temperature reactive LCE triggers the switch when a temperature violation has occurred, thereby switching the operating frequency of the sensor based on temperature changes. Additionally, a high-dielectric constant substrate and a single matching network that operates at two discrete frequencies are used to design our compact frequency-domain temperature sensor. Moreover, based on the RFID platform, this sensor operates effectively in close-proximity to other sensors. Also, is provides identification and temperature information through an autonomous, continuous, and cost-effective design. Therefore, the proposed sensor has the potential for operation in the Internet of Things (IoTs) applications, where large amounts of data is collected from numerous sensors to extract valuable information for the benefit of users, manufacturers, and delivery companies in the virtual domain of the internet. Finally, ANSYS HFSS and Circuit Designer are used for the simulation modeling. The performance of our sensor is validated using measurements and simulations that agree very well.
Predictive Model for Ice Formation on Superhydrophobic Surfaces (2011)

The prevention and control of ice accumulation has important applications in aviation, building construction, and energy conversion devices. One area of active research concerns the use of superhydrophobic surfaces for preventing ice formation. The present work develops a physics-based modeling framework to predict ice formation on cooled superhydrophobic surfaces resulting from the impact of supercooled water droplets. This modeling approach analyzes the multiple phenomena influencing ice formation on superhydrophobic surfaces through the development of submodels describing droplet impact dynamics, heat transfer, and heterogeneous ice nucleation. These models are then integrated together to achieve a comprehensive understanding of ice formation upon impact of liquid droplets at freezing conditions. The accuracy of this model is validated by its successful prediction of the experimental findings that demonstrate that superhydrophobic surfaces can fully prevent the freezing of impacting water droplets down to surface temperatures of as low as -20 to -25 °C. The model can be used to study the influence of surface morphology, surface chemistry, and fluid and thermal properties on dynamic ice formation and identify parameters critical to achieving icephobic surfaces. The framework of the present work is the first detailed modeling tool developed for the design and analysis of surfaces for various ice prevention/reduction strategies.
Convergent and Biomimetic Enantioselective Total Synthesis of (−)-Communesin F (2016)

The first biomimetic enantioselective total synthesis of (-)-communesin F based on a late-stage heterodimerization and aminal exchange is described. Our synthesis features the expedient diazene-directed assembly of two advanced fragments to secure the congested C3a-C3a′ linkage in three steps, followed by a highly efficient biogenetically inspired aminal reorganization to access the heptacyclic communesin core in only two additional steps. Enantioselective syntheses of the two fragments were developed, with highlights including the catalytic asymmetric halocyclization and diastereoselective oxyamination reactions of tryptamine derivatives, a stereoselective sulfinimine allylation, and an efficient cyclotryptamine-C3a-sulfamate synthesis by either a new silver-promoted nucleophilic amination or a rhodium-catalyzed C-H amination protocol. The versatile syntheses of the fragments, their stereocontrolled assembly, and the efficient aminal exchange as supported by in situ monitoring experiments, in addition to the final stage N1′-acylation of the communesin core, provide a highly convergent synthesis of (-)-communesin F.
Learning prosodic features using a tree representation (2001)

We describe experiments designed to learn associations between two types of intonational features, pitch accent and phrasing, from a tree-based corpus annotated with various intonational and syntactic features, for a concept-to-speech system. We show that using novel tree-based features improves the quality of boundary prediction over using only the linear orderbased features normally used in text-to-speech.

Interactive effects of carnitine status, dietary carnitine, and added fat on growth performance of weanling pigs (2001)

Two experiments were conducted to determine the interactive effects of carnitine status (with or without carnitine in diets fed to sows in gestation and lactation), and added fat and dietary carnitine in nursery diets on growth performance of weanling pigs. Feeding sows diets containing carnitine in gestation and lactation had no effect on growth performance of their pigs through 27-d after weaning. A carnitine by fat interaction (P<0.05) was observed for ADFI from d 0 to 7 and ADG from d 0 to 27 in Exp. 1 with pigs fed carnitine and no added fat appearing to have the best performance. In exp. 2, added carnitine had little effect on growth performance, whereas added fat improved feed efficiency. In conclusion, no benefit to growth performance was observed from adding both carnitine and fat to the diet of weanling pigs in these experiments.; Swine Day, Manhattan, KS, November 15, 2001
Platinum-Bismuth Bimetallic Catalysts: Synthesis, Characterization and Applications (2015)

Bimetallic catalysts have been explored and shown to exhibit unique characteristics which are not present in monometallic catalysts. Platinum is well known as an effective catalyst for oxidation and reduction reactions, and it can be made more effective when bismuth is introduced as a promotor. Thus, the effectiveness of the Pt-Bi catalyst was demonstrated in prior work. What is not clear, however, is the mechanism behind the catalyst function; why addition of bismuth to platinum decreases deactivation and increases selectivity, and how effective would the Pt-Bi catalyst be in deoxygenation reactions? In this work, the effectiveness of different variations of the Pt-Bi catalyst was explored for the deoxygenation of guaiacol. Methane was selected as the model reductant. Two Pt-Bi catalysts with different metal ratios were prepared, tested and characterized to reveal the catalyst’s structure. Methods used in characterization included SEM, TEM and BET measurements. Representative catalysts were then tested in a fixed-bed reactor for performance.
