Preclinical Evaluation of the Versius Surgical System, a New Robot-assisted Surgical Device for Use in Minimal Access Renal and Prostate Surgery (2020)

In this report, we looked at the usability of a new robot-assisted surgical device for renal and prostate surgery by testing the system in cadavers and pigs. We found that a number of different surgeons and operating team personnel were able to use the system to successfully complete the procedures under evaluation. We conclude that the system is ready to be tested in live human studies.
A proposal for a solution of the TCP short-term deadlock problem (2002)

Since the TCP is the most important transport protocol in the Internet, it should be strongly encouraged to improve its performance and usability. In this paper, we discuss one of major drawbacks called "TCP short-term deadlock problem" in the current TCP implementations. Because of inadequate delayed acknowledgment handling, the short-term deadlocks where data are transferred intermittently occur repeatedly under some conditions. As its result, the end-to-end throughput on the TCP connection is extremely decreased. Some solutions have been proposed for this problem, however, they turn off its delayed acknowledgment mechanism in order to eliminate the short-term deadlocks, therefore, they add more meaningless traffic. We propose yet another solution for this problem. Our solution can eliminate the deadlocks and add little traffic more. In this paper, we first discuss the nature of the short-term deadlock. We then discuss our solutions and show its performance evaluation.

Indicators of high technology competitiveness of 28 countries (2014)

Georgia Tech, with support from the National Science Foundation, has now completed a decade of development of indicators of national high technology competitiveness. This paper reports on the standing, emphasis, and rate of change of high tech competitiveness for 28 nations. Results show strong standing for the '4 Asian tigers', comparable to many Western European countries. Five of our '6 Asian cubs' show dramatic rates of growth in high tech production and export capabilities; the 4 Tigers no longer show strong growth. Patterns are presented and discussed as well for 'the Big 3' (Japan, USA, Germany), three non–European developed economies, two former East Bloc countries, and three Latin American nations. Our panel of 180 experts project a dramatic broadening of global high tech export competition over the coming 15 years.
Trade facilitation: new issues in a development context (2003)

The relationship between economic growth, trade facilitation, and development is relatively simple in theory. Economic theory suggests that development is enhanced through income growth -- which is driven through increased trade. Expansion of trade is achieved, at least in part, through programs to lower transaction costs in goods and services crossing borders. Although these linkages appear straightforward, measuring the benefits of trade facilitation based on empirical evidence is much more challenging. This is particularly true when considering capacity building priorities.
uniMorph (2015)

Researchers have been investigating shape-changing interfaces, however technologies for thin, reversible shape change remain complicated to fabricate. uniMorph is an enabling technology for rapid digital fabrication of customized thin-film shape-changing interfaces. By combining the thermoelectric characteristics of copper with the high thermal expansion rate of ultra-high molecular weight polyethylene, we are able to actuate the shape of flexible circuit composites directly. The shape-changing actuation is enabled by a temperature driven mechanism and reduces the complexity of fabrication for thin shape-changing interfaces. In this paper we describe how to design and fabricate thin uniMorph composites. We present composites that are actuated by either environmental temperature changes or active heating of embedded structures and provide a systematic overview of shape-changing primitives. Finally, we present different sensing techniques that leverage the existing copper structures or can be seamlessly embedded into the uniMorph composite. To demonstrate the wide applicability of uniMorph, we present several applications in ubiquitous and mobile computing.

Lumbar pseudarthrosis: a review of current diagnosis and treatment (2015)

OBJECT Failed solid bony fusion, or pseudarthrosis, is a well-known complication of lumbar arthrodesis. Recent advances in radiographic technology, biologics, instrumentation, surgical technique, and understanding of the local biology have all aided in the prevention and treatment of pseudarthrosis. Here, the current literature on the diagnosis and management of lumbar pseudarthroses is reviewed. METHODS A systematic literature review was conducted using the MEDLINE and Embase databases in order to search for the current radiographie diagnosis and surgical treatment methods published in the literature (1985 to present). Inclusion criteria included: 1) published in English; 2) level of evidence I-III; 3) diagnosis of degenerative lumbar spine conditions and/or history of lumbar spine fusion surgery; and 4) comparative studies of 2 different surgical techniques or comparative studies of imaging modality versus surgical exploration. RESULTS Seven studies met the inclusion criteria for current radiographie imaging used to diagnose lumbar pseudarthrosis. Plain radiographs and thin-cut CT scans were the most common method for radiographie diagnosis. PET has been shown to be a valid imaging modality for monitoring in vivo active bone formation. Eight studies compared the surgical techniques for managing and preventing failed lumbar fusion. The success rates for the treatment of pseudarthrosis are enhanced with the use of rigid instrumentation. CONCLUSIONS Spinal fusion rates have improved secondary to advances in biologies, instrumentation, surgical techniques, and understanding of local biology. Treatment of lumbar pseudarthrosis includes a variety of surgical options such as replacing loose instrumentation, use of more potent biologies, and interbody fusion techniques. Prevention and recognition are important tenets in the algorithm for the management of spinal pseudarthrosis.
Controlled group V intermixing in InGaAsP quantum well structures and its application to the fabrication of two section tunable lasers (2002)

We report the technique of controlled group V quantum well intermixing (QWI) in a compressively strained In0.76Ga0.24As0.85P0.15/In0.76Ga0.24As0.52P0.48 multiquantum well laser structure and its application to the fabrication of two-section tunable lasers. The blueshift of the band-gap energy was enhanced by capping the samples with films of SiO2 or low-temperature grown InP, while suppressed by a SixNy film with a refractive index of about 2.1. Spatially selective band-gap tuning was achieved by patterning the dielectric film into dot and strip arrays with different surface coverage. Time-of-flight secondary ion mass spectra showed that the enhanced blueshift was caused by the interdiffusion of group V atoms between the quantum wells and barriers. A group V interstitial interdiffusion mechanism is proposed for the sample capped with SiO2 and this is supported by the even more efficient intermixing induced by low-temperature InP, which contains a high concentration of excess phosphorus. A two-section tunable laser operating around 1.55 μm was fabricated using this QWI technology. A tuning range of about 10 nm was demonstrated by simply changing the current injected into the phase tuning section.

High Pressure Polymerization of Ethylene. an Improved Mathematical Model for Industrial Tubular Reactors (1996)

This work presents an exhaustive mathematical model for the high pressure polymerization of ethylene in tubular reactors of configuration similar to that encountered in the industry. Multiple injection of monomer, mixtures of initiators and chain transfer agents are considered together with realistic flux configurations. Typical heat transfer coefficients are estimated from industrial plant data. The effects of pressure pulse on the reactor behavior are also analyzed. Instantaneous temperature profiles produced by such pressure pulse were recovered from stationary simulations showing a very good agreement with the corresponding experimental data. The model features are demonstrated by predictions of temperature, concentrations of reactants and products and molecular properties as a function of reactor length. Also, appropriate predictive capabilities are disclosed by comparison of model simulation results and experimental data The generation of a high temperature initiator, derived from oxygen, is assessed by comparison of temperature profiles corresponding to runs with and without oxygen.
Characterization of Transient Wall Heat Load for a Low NOx Lean Premixed Swirl Stabilized Can Combustor Under Reacting Conditions (2020)

Abstract Modern combustor design optimization is contingent on the accurate characterization of the combustor flame side heat loads. Knowledge of regions of high and low heat loads on the liner wall helps designers optimize the cooling designs. The present work focuses on the experimental measurement of the transient heat load along a fused silica (quartz) optical can combustor under reacting conditions for a swirl stabilized premixed methane-air flame. Equivalence ratio was varied from 0.55 to 0.65. Reynolds number based on combustor diameter was varied from 12500 to 18000, where the preheated air temperature was approximately 373 K. The percentage of pilot fuel was varied from 6% to 10% of the main fuel flow rate. Inner and outer walls of the liner were painted with a high temperature flat black paint with an azimuthal offset to aid in infrared measurement of the wall temperature using an infrared camera. Particle Image Velocimetry (PIV) was employed to visualize the flow field for various reacting conditions studied in this work. Based on the heat transfer study, a detailed report of transient heat load along the length of the liner wall for varying reacting conditions has been presented here. The location of impingement of the flame onto the liner and velocity of the flow field were obtained from PIV measurements. Wall heat load at various planes along the length of the liner have been presented. Repeatability of this transient experiment was within 10% between eight different runs for various locations along the length of the liner, except for the region close to flame impingement zone. In the impingement zone, liner heat load varied by about 25% between different runs. It was observed that the change in heat load upstream of the location of impingement on the liner was insignificant with change in pilot ratio as the system tends towards a steady state, contrary to the regions downstream. Higher Reynolds number and equivalence ratios increased the heat load on the liner as expected.

CHA-Type Zeolite Prepared by Interzeolite Conversion Method Using FAU and LTL-Type Zeolite: Effect of the Raw Materials on the Crystallization Mechanism, and Physicochemical and Catalytic Properties (2020)

The effect of the raw materials including parent zeolite as aluminosilicate sources and organic structure-directing agents (OSDAs) on the crystallization mechanism, and physicochemical and catalytic properties of the CHA-type aluminosilicate zeolite was investigated. For this purpose, the FAU-type and the LTL-type zeolites were used as raw material, and trymethyladamantyl ammonium hydroxide and tetraethyl ammonium hydroxide were used as OSDAs. We firstly found that the CHA-type aluminosilicate zeolite was crystallized from the combination of the LTL-type zeolite and tetraethyl ammonium hydroxide as raw materials. The crystallization behaviors were also monitored in detail. The crystallization was delayed by using the LTL-type zeolite as the starting material regardless of the type of OSDA because of the low solubility of the LTL-type zeolite compared to the FAU-type zeolite. We have found that the Al distribution in the CHA framework was dependent on the raw materials. Thus, the prepared CHA-type aluminosilicate zeolite from the LTL-type zeolite exhibited a high thermal stability and catalytic performance in the methanol to olefins reaction.
Detection and quantification of delamination in laminated plates from the phase of appropriate guided wave modes (2015)

Applicability of specific Lamb wave modes for delamination detection and quantification in a laminated aluminum plate is investigated. The Lamb modes were generated in the plate using a broadband piezoelectric transducer structured with a rigid electrode. Appropriate excitation frequencies and modes for inspection were selected from theoretical dispersion curves. Sensitivity of antisymmetric and symmetric modes for delamination detection and quantification has been investigated using the Hilbert–Huang transform. The mode conversion phenomenon of Lamb waves during progressive delamination is observed. The antisymmetric mode is found to be more reliable for delamination detection and quantification. In this investigation, the changes in the phase of guided Lamb wave modes are related to the degree of delamination, unlike other studies, where mostly the attenuation of the propagating waves has been related to the extent of the internal damage, such as cracks and corrosions. Appropriate features for delamination detection and quantification are extracted from the experimental data.
Tumor secreting high levels of IL-15 induces specific immunity to low immunogenic colon adenocarcinoma via CD8+ T cells. (2004)

Although interleukin (IL)-15 augments innate and acquired immunities, IL-15 expression is controlled at the levels of transcription, translation and intracellular trafficking. We constructed plasmid vectors encoding the murine mature-IL-15 cDNA linked to an Igkappa leader sequence and full-length murine IL-15 cDNA to evaluate the efficacy of the mature-IL-15 vector. Weakly immunogenic colon 26 cells were transfected with the above-mentioned vectors or with empty vector (mock). Transfectants with mature-IL-15 produced significantly higher levels of IL-15 than did transfectants with full-length IL-15. When injected into syngeneic BALB/c mice, transfectants secreting high levels of IL-15 were rejected completely. Depletion of natural killer cells or CD4+ T cells did not affect the growth of transfectants. In contrast, transfectants treated with anti-CD8 antibody re-grew 1 month later after implantation. These findings indicate that CD8+ T cells are required for complete rejection of the tumor. Gene therapy with transfectants expressing mature-IL-15 containing the Igkappa leader sequence may be useful as a tumor vaccine.
Going mobile: the next horizon for multi-million gate designs in the semi-conductor industry (2002)

The complexity of a System-on-Chip design is not only in the million transistors packed in a square millimeter. The major challenge for technical success of a SoC is to make sure that millions lines of software fit in with millions of gates. In this paper, the problem of multi-million gate design is illustrated from the viewpoint of the practical development of a complex digital system at STMicroelectronics for a GSM/GPRS cellular application.
HIMAA Workforce Survey 1991/1992 (1993)

In 1991, and again in 1992, the Health Information Management Association of Australia (HIMAA), formerly Medical Record Association of Australia (MRAA), distributed a Workforce Survey to all members to collect information about the demographic, professional and employment characteristics of HIMAA members. There was a response rate 66.8% in 1991 and 40% in 1992, which rise to 80.9% in 1991 and 51.7% in 1992 for responses from full members. The collection will continue on an annual basis, providing a cumulative database and the opportunity for trend analysis.
Mechanistic impact of oligomer poisoning by dominant-negative CARD11 variants (2022)

The CARD11 scaffold controls antigen receptor signaling to NF-κB, JNK, and mTOR. Three classes of germline mutations in CARD11 cause Primary Immunodeficiency, including homozygous loss-of-function (LOF) mutations in CARD11 deficiency, heterozygous gain-of-function (GOF) mutations in BENTA disease, and heterozygous dominant-negative LOF mutations in CADINS. Here, we characterize LOF CARD11 mutants with a range of dominant-negative activities to identify the mechanistic properties that cause these variants to exert dominant effects when heterozygous. We find that strong dominant negatives can poison signaling from mixed wild-type:mutant oligomers at two steps in the CARD11 signaling cycle, at the Opening Step and at the Cofactor Association Step. Our findings provide evidence that CARD11 oligomer subunits cooperate in at least two steps during antigen receptor signaling and reveal how different LOF mutations in the same oligomeric signaling hub may cause disease with different inheritance patterns.
A WiX RF transceiver for Gbps wireless communication (2011)

A UWB communication transceiver(TRX) named `WiX(Wireless eXpress) TRX' is proposed, which is featured with three WiMedia UWB RF channels and a new small planar type OMUX, for high data rate TX and RX. Each WiMedia UWB RF channel can treat more than 500Mbps wireless data, and the OMUX combines and splits the output and input of three WiMedia UWB RF channels in the TX and RX modes, respectively. The Wix TRX for the Gbps wireless data communication is designed and implemented, and its performance is verified by the experimental demonstration.
Chemical composition of propolis from Canada, its antiradical activity and plant origin (2005)

The chemical composition of propolis from two regions in Canada was studied: Boreal forest and Pacific coastal forest that lay outside the area of distribution of Aigeiros poplars, the usual propolis source plants. In the sample from Victoria, p-hydroxyacetophenone, benzyl hydroxybenzoate and cinnamic acid were the major components, accompanied by significant amounts of dihydrochalcones, which allowed the identification of its plant source: Populus trichocarpa of Section Tacamahaca. Three dihydrochalcones were new for propolis. The sample from Richmond was characterized by large amounts of p-coumaric and cinnamic acid, typical for poplars of Section Leuce, subsection Trepidae, its plant source was identified as P. tremuloides. Both samples showed good radical scavenging activity against DPPH. Obviously, Northern type propolis is a promising potential source of biologically active substances and deserves further investigation.
Preparation by pulsed laser deposition and characterization of ZrO/sub 2/, HfO/sub 2/ and PrO/sub x/ thin films for high-k gate insulator (2003)

High-k thin films of ZrO/sub 2/, HfO/sub 2/ PrO/sub x/ of /spl sim/10 nm thickness have been prepared by pulsed laser deposition (PLD), and characterized in microscopic structure and electrical properties. Crystallization is promoted in ZrO/sub 2/ films deposited above 400/spl deg/C, but a significant XRD peak was not observed in the ZrO/sub 2/ film grown below 400/spl deg/C. Moreover, density of the film is confirmed to saturate above 400/spl deg/C by grazing incident angle X-ray reflectance. The leakage current is decreased by increasing growth temperature, but an equivalent-oxide thickness (EOT) obtained from accumulation capacitance of C - V characteristics becomes large. HfO/sub 2/ films show the similar behaviors to ZrO/sub 2/ films. The films deposited at 400/spl deg/C were annealed at 400/spl deg/C in O/sub 2/ gas to reduce the leakage, but the EOTs become large. So, these films were irradiated with oxygen radical at the pressure of 10/sup -3/ Pa both to prevent the growth of interfacial layer and to enhance the oxidation of only the films. Although the leakage of ZrO/sub 2/ films can be reduced by oxygen radical irradiation, only small improvement is observed in the PrO/sub x/ films.
An Integrated Wireless Wearable Sensor System for Posture Recognition and Indoor Localization (2016)

In order to provide better monitoring for the elderly or patients, we developed an integrated wireless wearable sensor system that can realize posture recognition and indoor localization in real time. Five designed sensor nodes which are respectively fixed on lower limbs and a standard Kalman filter are used to acquire basic attitude data. After the attitude angles of five body segments (two thighs, two shanks and the waist) are obtained, the pitch angles of the left thigh and waist are used to realize posture recognition. Based on all these attitude angles of body segments, we can also calculate the coordinates of six lower limb joints (two hip joints, two knee joints and two ankle joints). Then, a novel relative localization algorithm based on step length is proposed to realize the indoor localization of the user. Several sparsely distributed active Radio Frequency Identification (RFID) tags are used to correct the accumulative error in the relative localization algorithm and a set-membership filter is applied to realize the data fusion. The experimental results verify the effectiveness of the proposed algorithms.
