Acoustic Time-frequency Approach to Condition Monitoring of Ventricular Assistive Devices (2018)

This paper studies the acoustic signals of left ventricular assist devices (LVADs) as it relates to machine health. Current LVAD condition monitoring requires examination from trained medical professionals, and is both inefficient and roughly-prognostic. To better quantify a patient's condition, the diagnostic method must be robust, non-invasive, and simple to apply. The concept behind this work is to determine an identifying pattern between the specific acoustics produced by an LVAD with the related overall health of the patient. Due to the cycle-to-cycle variance of heart sounds, the continuous wavelet transform (CWT) is applied to the objective audio signal so that a high resolution spectra is obtained. From this, region specific image features are developed and subsequently used in a support vector machine (SVM) algorithm to classify between health conditions. The preliminary goal is to develop an accurate and non-invasive diagnostic method for determining patient health that can be applied for any LVAD variant. This process is validated through in vitro testing using a DC motor as an LVAD proxy.
Instrumenting a Rowing Ergometer for Improved Training (2013)

Rowing ergometers are used by athletes for indoor training and performance improvement. Typical commercial ergometers provide some information (for example power output and covered distance), but these indications are typically estimated starting from the fan speed and thus are not very reliable as already pointed out in the literature. The present paper presents the work done to fully instrument a commercial rowing ergometer in order to directly measure all relevant quantities for improved training: the seat, the handlebar and the stretchers have been redesigned and equipped with force and displacement sensors able to measure both the dynamic and kinematic behavior of the athlete. In this way the interaction of the athlete with the rowing machine is fully known, together with the direct measurement of the instantaneous rowing power output. Some results are also presented and discussed.
Dynamics and fragmentation of encapsulated gas bubbles (2001)

The development of ultrasound contrast agents has fostered an interest in the theoretical dynamics of encapsulated gas bubbles. Originally, micron-sized agents were constructed for diagnostic imaging purposes with a thin shell (&amp;lt;15 nm) of lipid, protein, or polymeric materials. New therapeutic applications for localized drug delivery have led to an interest and development of micron-size bubbles with a thick fluid shell (∼500 nm). Previously some experimental acoustic levitation studies have investigated the capillary wave development on millimeter-size liquid shells. The nonlinear oscillations and fragmentation have not been extensively investigated from the theoretical standpoints. A generalized Rayleigh–Plesset equation has been developed that includes the effects of a thick viscous fluid shell. The equation is compared with other theoretical encapsulated bubble formulations and some recent experimental observations. For a 4.0 μ bubble, with a 500 nm shell of viscosity of 28 cP, insonified over 5 cycles, a maximum relative expansion of 2.2 times the equilibrium radius is predicted at 2.25 MHz and 3.1 times at 1.5 MHz. Predictions from this model regarding the scaling of radial expansion with changes in pressure and frequency have been validated with experimental data.
The performance of serial, matched-filter acquisition in direct-sequence packet radio communications (2002)

The performance of a noncoherent, serial acquisition technique is evaluated for direct-sequence spread-spectrum packet communications. The output of a filter matched to the packet's preamble is sampled at twice the chip rate during acquisition, and each sample is compared with a fixed acquisition threshold. The effect of sample-timing error on the acquisition performance is examined.
Propensity matched analysis of bilateral internal mammary artery versus single left internal mammary artery grafting at 17-year follow-up: validation of a contemporary surgical experience (2012)

Perioperative complications do not increase with the use of BIMAs. Long-term survival is optimized with off-pump CABG and BIMA grafting. The low morbidity and mortality rates in this series are likely due to the continuous evolution of technology and the adoption of less invasive options for CABG patients. A more widespread use of BIMAs in CABG patients would continue to improve the overall excellent short- and long-term results of this operation.
Non-dyadic fisheye lens correction model for image enhancement (2015)

This paper presents a non-dyadic framework to improve example-based enhancement of radially distorted images acquired by a very wide-angle lens. In order to remove both jagging and blurring artifacts in the correction process of the fisheye lens' barrel distortion, the proposed method first performs non-dyadic or multiple-step geometric correction based on the parabolic equation-based lens distortion model. At each correction step, an example-based image enhancement method removes undesired geometric correction artifacts such as jagging and blurring. Experimental results demonstrate that the proposed method outperforms existing fisheye lens image enhancement methods in the sense of both subjective and objective measures. Based on both theoretical advancement and experimental results, the proposed method can be used for various wide-view imaging applications including vehicle front- and rear-view cameras and wide-angle video surveillance systems.
Initial Evaluation of the Clarion CII Cochlear Implant: Speech Perception and Neural Response Imaging (2002)

The Clarion CII is a promising cochlear implant with which our first 10 patients have obtained excellent speech perception results. The NRI system yields high quality signals with a limited number of sweeps at a high sampling rate.
CRDOCK: An Ultrafast Multipurpose Protein–Ligand Docking Tool (2012)

An ultrafast docking and virtual screening program, CRDOCK, is presented that contains (1) a search engine that can use a variety of sampling methods and an initial energy evaluation function, (2) several energy minimization algorithms for fine tuning the binding poses, and (3) different scoring functions. This modularity ensures the easy configuration of custom-made protocols that can be optimized depending on the problem in hand. CRDOCK employs a precomputed library of ligand conformations that are initially generated from one-dimensional SMILES strings. Testing CRDOCK on two widely used benchmarks, the ASTEX diverse set and the Directory of Useful Decoys, yielded a success rate of ~75% in pose prediction and an average AUC of 0.66. A typical ligand can be docked, on average, in just ~13 s. Extension to a representative group of pharmacologically relevant G protein-coupled receptors that have been recently cocrystallized with some selective ligands allowed us to demonstrate the utility of this tool and also highlight some current limitations. CRDOCK is now included within VSDMIP, our integrated platform for drug discovery.
Opportunities and challenges of developing thermostable vaccines (2009)

All vaccines lose potency over time and the rate of potency loss is temperature-dependent. Therefore, cold-chain systems have been established to ensure that the potency of vaccines is maintained by storing them under refrigerated conditions (in most cases between 2 and 8 degrees C) until the point of use. This article aims to review the approaches being used to develop thermostable vaccine formulations that would be resistant to damage caused by freezing or excessive heat, and that could reduce dependence on the cold chain. The challenges associated with the implementation of these novel formulations are discussed, as well as the potential benefits and opportunities of taking vaccines out of the cold chain.
BLOOMhouse: a zero net energy house (2013)

The 2007 University of Texas Solar Decathlon House is called the BLOOMhouse because it represents the "seed" of new ideas for zero net energy housing.The University of Texas student team developed a prefabricated 7.9 kW stand-alone solar-powered modular house that sits lightly on the land and forms the superstructure for photovoltaic technologies and a sustainable approach to the building envelope.The prefabricated house can be adapted to a specific site and modified for the needs of a different site within a different climatic zone, and client context.Recognizing that consumers look to Solar Decathlon entries for ideas of how to integrate renewable energy technologies into their own homes this house will serve as a working example to homeowners, homebuilders, and architects.The Solar Decathlon is an international initiative and University competition sponsored by the U.S. Department of Energy, designed to stimulate research, industry and education to advance renewable energy technologies, with a specific focus on building-integrated photovoltaics.Now entering its fourth cycle, the Decathlon provides a unique opportunity to envision, fabricate and test the possibilities of highly efficient modern dwellings.Our team of architecture and engineering faculty and students under the direction of Professor Michael Garrison, Professor Samantha Randall, Professor Atila Novoselac, and Lecturer Russell Krepart constructed a completely stand-alone solar-powered home that serves as a catalyst for change, leading the residential housing industry toward more sustainable practices while addressing the need for well designed, appropriately diverse, economically viable, and environmentally responsible housing.Through use of solar power and energy efficient design, this project offers homeowners the means to directly participate in the energy economy, moving from energy consumers to energy producers.
Disordered protein-graphene oxide co-assembly and supramolecular biofabrication of functional fluidic devices (2020)

Supramolecular chemistry offers an exciting opportunity to assemble materials with molecular precision. However, there remains an unmet need to turn molecular self-assembly into functional materials and devices. Harnessing the inherent properties of both disordered proteins and graphene oxide (GO), we report a disordered protein-GO co-assembling system that through a diffusion-reaction process and disorder-to-order transitions generates hierarchically organized materials that exhibit high stability and access to non-equilibrium on demand. We use experimental approaches and molecular dynamics simulations to describe the underlying molecular mechanism of formation and establish key rules for its design and regulation. Through rapid prototyping techniques, we demonstrate the system's capacity to be controlled with spatio-temporal precision into well-defined capillary-like fluidic microstructures with a high level of biocompatibility and, importantly, the capacity to withstand flow. Our study presents an innovative approach to transform rational supramolecular design into functional engineering with potential widespread use in microfluidic systems and organ-on-a-chip platforms.
Recent Research Progress of Coenzyme Q_10 (2003)

There are four methods, propagation cell extraction, plant cell culture, chemical synthesis and microbiological fermentation, for the preparation of coenzyme Q10. Among these, microbiological fermentation method is the hot spot of development in recent years at home and abroad and is considered as a process with broad prospect. It is pointed out that attention should be paid on the sieving of coenzyme Q10 strains of high yield so as to realize the industrial production of coenzyme Q10 by microbiological fermentation.
Isolation of Bartonella vinsonii subsp. berkhoffii Genotype II from a Boy with Epithelioid Hemangioendothelioma and a Dog with Hemangiopericytoma (2009)

In this report, we describe isolation of Bartonella vinsonii subsp. berkhoffii genotype II from a boy with epithelioid hemangioendothelioma and a dog with hemangiopericytoma. These results suggest that B. vinsonii subsp. berkhoffii may cause vasoproliferative lesions in both humans and dogs.
Detecting induced $p \pm ip$ pairing at the Al-InAs interface with a quantum microwave circuit (2021)

Superconductor-semiconductor hybrid devices are at the heart of several proposed approaches to quantum information processing, but their basic properties remain to be understood. We embed a two-dimensional Al-InAs hybrid system in a resonant microwave circuit, probing the breakdown of superconductivity due to an applied magnetic field. We find a strong fingerprint from the two-component nature of the hybrid system, and quantitatively compare with a theory that includes the contribution of intraband $p \pm i p$ pairing in the InAs, as well as the emergence of Bogoliubov-Fermi surfaces due to magnetic field. Separately resolving the Al and InAs contributions allows us to determine the carrier density and mobility in the InAs.
Traffic noise barriers: a case study on the installation of barriers on the Western Arterial, Brisbane (1986)

The moggill road - jerrang street section of the western arterial in Brisbane has been constructed through a residential area. Traffic noise barriers were included as an integral part of the design of this road facility in order to reduce the impact of traffic noise on the surrounding suburban community. The noise studies, impact assessment and design of the barriers are discussed together with the main roads Queensland's approach to traffic noise investigations. The assessment of the impact of the barrier is evaluated in the following manner: (i) the accuracy of the prediction model. (Ii) the effectiveness of the barrier in reducing noise levels. (Iii) the total acoustic effect of the road with barrier on the acoustic environment of the adjacent residences. (Iv) the effectiveness of the barrier from the adjacent residents' point of view. The following conclusions have been drawn: (i) the assessment procedures are adequate for practical application. (Ii) the barrier designs have been successful in that a major noise generator has been introduced into a residential area with minimal adverse noise effects. (Iii) the design of the barrier appears to have been an adequate compromise between acoustic requirements and aesthetics (a).
Selective plasma etching of Ge substrates for thin freestanding GaAs-AlGaAs heterostructures (1991)

Selective plasma etching of Ge with a CF4/O2 mixture is used to produce freestanding GaAs-AlGaAs thin films. The etch rate of Ge substrates is as high as 150 μm/h at temperatures of 75 °C under optimized conditions and with a negligible etch rate for GaAs and AlGaAs materials. This plasma etching technique, combined with a lattice-matched growth of GaAs-AlGaAs structures on Ge substrates, has a variety of potential device applications. The characteristics of this etch process and the photoluminescence of freestanding AlGaAs-GaAs structures are presented.
Run-time phenomena in dynamic software updating (2011)

The development of a dynamic software updating system for statically-typed object-oriented programming languages has turned out to be a challenging task. Despite the fact that the present state of the art in dynamic updating systems, like JRebel, Dynamic Code Evolution VM, JVolve and Javeleon, all provide very transparent and flexible technical solutions to dynamic updating, case studies have shown that designing dynamically updatable applications still remains a challenging task. This challenge has its roots in a number of run-time phenomena that are inherent to dynamic updating of applications written in statically-typed object-oriented programming languages. In this paper, we present our experience from developing dynamically updatable applications using a state-of-the-art dynamic updating system for Java. We believe that the findings presented in this paper provide an important step towards a better understanding of the implications of dynamic updating on the application design.
MACHINE PERCEPTION OF THREE-DIMENSIONAL SOLIDS, (1963)

In order to enable a computer to construct and display a three-dimensional array of solid ob jects from a single two-dimensional photograph, the rules and assumptions of depth perception have been carefully analyzed and mechanized. It is assumed that a photograph is a perspective projection of a set of objects which can be con-structed from transformations of known three dimensional models, and that the objects are sup ported by other visible objects or by a ground plane. These assumptions enable a computer to obtain a reasonable, three-dimensional descrip tion froom the edge information in a photograph by means of a topological, mathematical process. A computer program has been written which can process a photograph into a line drawing, trans form the line drawing into a three-dimensional representation, and finally, display the three dimensional structure with all the hidden lines removed, from any point of view. The 2-D to 3-D construction and 3-D to 2-D display processes are sufficiently general to handle most collections of planar-surfaced objects and provide a valuable starting point for future investigation of com puter-aided three-dimensional systems.

ABSENCE OF HOST‐CELL INFLUENCE ON BINDING SPECIFICITY OF HERPES SIMPLEX VIRUS TYPE 1 INDUCED FC RECEPTOR (1987)

Herpes simplex virus (HSV) infected cells express on their surface a receptor with affinity to the Fc portion of immunoglobulin G (IgG). The influence of the infected host cell on the specificity of the receptor was investigated with radiolabeled human IgG Fc fragment and four animal IgGs (rabbit, dog, cow, and rat) and eight human and animal (primate, rabbit, dog, cow, and rat) fibroblastoid and epithelioid cell lines. Human IgG Fc, rabbit IgG and cow IgG bound to all cell lines infected with HSV type 1 strain F (HSV-1 F), whereas dog IgG and rat IgG did not bind to any of these cells. The same binding pattern was seen when two additional HSV-1 strains infected rabbit epithelial (GMK AH1) cells. The results support the view that the specificity of the HSV Fc receptor is mainly under viral control and not primarily influenced by the species of the host cell.
Magnetic field and stress analysis of saturated steel (1988)

The magnetomechanical behavior of ferromagnetic material is analyzed. The behavior is nonlinear because of the strong nonlinear B-H magnetization relation. Finite-element analyses of 2-D and 3-D magnetic field, magnetic torque, and deformation of a beam-plate arrangement and a circular tube are described. Experimental results showing good agreement with the numerical results are reported.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">&gt;</ETX>
Quantitation of HER-2/neu and c-myc gene amplification in breast carcinoma using fluorescence in situ hybridization. (1997)

HER-2/neu and c-myc amplification or overexpression have been reported to be associated with poor prognosis in breast carcinoma. The prognostic significance, however, remains somewhat controversial, partly because of discrepancies among different methodologies used for detection of the oncogene amplification or overexpression. Fluorescence in situ hybridization (FISH) has recently been shown to be a useful technique for analyzing genetic alterations in interphase nuclei in various tumors. In this study, FISH was used to quantitate HER-2/ neu and c-myc gene amplification in touch preparations of frozen tissue from 100 node-negative breast carcinomas. HER-2/neu amplification was found to be associated with an abnormal DNA index (P < .001) and tumor size (P < .04). Amplification of c-myc was associated with S phase (P < .0003), abnormal DNA index (P < .003), and a negative estrogen receptor status (P < .01). The coamplification of both oncogenes was strongly associated with an abnormal DNA index (P < .0001) and with tumor size (P < .009). The use of FISH for detection of HER-2/neu gene amplification was 92% concordant with immunocytochemistry (ICC) used for detection of overexpression of HER-2/neu protein. Fifteen of the 100 cases were both amplified for HER-2/neu by FISH and positive by ICC analysis. Seven cases without HER-2/neu gene amplification demonstrated HER-2/neu protein overexpression by ICC. One HER-2/neu-amplified case was negative by ICC. Repeat analysis of a subset of cases showed FISH to be a more reproducible method than ICC in the analysis of HER-2/neu in touch preparations of breast carcinoma. FISH is a rapid and reproducible method that allows the accurate measurement of the level of oncogene amplification within interphase nuclei. The use of FISH should provide a more accurate assessment of the prognostic significance of oncogene amplification in breast carcinoma.
The transcriptional regulator gene phrR in Sinorhizobium meliloti WSM419 is regulated by low pH and other stresses (1998)

The phrR gene in Sinorhizobium meliloti (previously known as Rhizobium meliloti) WSM419, directly downstream from actA, is induced by low pH or certain stresses (e.g. high concentrations of Zn2+, Cu2+, H2O2 or ethanol), but not in stationary phase or by other stresses (e.g. phosphate limitation, elevated temperature, high concentrations of sucrose or iron). A DNA fragment containing the wild-type phrR gene could not be cloned and inverse PCR was therefore used to amplify a 3.5 kb BamHI fragment containing phrR from the mutant S. meliloti TG2-6 (actA::Tn5). DNA fragments from a BamHI/SalI digest of the amplified product were cloned into pUK21 and sequenced. The phrR open reading frame contiguous to actA appears to code for a 15.2 kDa protein showing significant identity with the proteins encoded by y4wC and y4aM in Rhizobium sp. NGR234. All three proteins resemble transcriptional regulators in containing a DNA-binding helix-turn-helix motif similar to that reported for URF4 in Rhodospirillum rubrum and repressors in coliphage.
Stereotypes towards Stuttering for Those Who Have Never Had Direct Contact with People Who Stutter: A Randomized and Stratified Study (2003)

Research suggests that many people hold pervasive negative stereotypes towards persons who stutter and that to date, success in changing these attitudes has been limited. However, few studies have selected people who had not had direct contact with a person who stutters or employed a true randomized and stratified selection of people from the community to assess attitudes towards stuttering. To assess stereotypes, a randomized and stratified investigation was conducted by telephone interview to assess the type of stereotypes 502 people from households in the state of New South Wales. Australia have about stuttering. Consenting persons were given a brief introduction to the research and a description of stuttering. Then they were asked if they or any person living in their household stuttered or whether they knew or had ever met any one who stuttered. If answers were no, they were asked to participate. If they answered yes to either question they were thanked and not asked to participate. Analysis showed that a large number believe persons who stutter are shy, self-conscious, anxious people who lack confidence. In contrast, many also believe they would not be embarrassed talking to someone who stutters, that they have average or above average intelligence, and are capable of holding responsible work-related positions. While this research yields a mixture of negative and positive community stereotypes, a significant portion of society continue to show little knowledge of the causes of the disorder.
