Reduction in Variability of Acetabular Cup Abduction Using Computer Assisted Surgery: A Prospective and Randomized Study (2002)

Optimal orientation of the acetabular component of a total hip prosthesis is an important factor in determining the early and long-term result of a total hip arthroplasty (THA). Conventional positioning of the cup component is usually done using a free-hand method, or with the help of a mechanical acetabular alignment guide. However, these methods have proven to be inaccurate, and a great variation in orientation of the cup is found postoperatively. In this study, we wished to determine if the variability of the abduction angle of acetabular cups could be reduced with the use of computer navigation. The abduction angles of the acetabular components of three groups of 50 THAs were assessed. In the first group, a free-hand method was used to position the cup component. This group was operated in the period before we started using computer navigation for hip surgery. In the second group, CT-based computer navigation was used to plan and help position the cup. The third group consisted of 50 THA cases in which a free-hand method was used to position the cup, although these procedures were performed in the period after we had begun using the Computer Assisted Surgery (CAS) system. The variability in cup abduction angle was assessed in all three groups and compared. There was a significant reduction in variability in the CAS group compared to the first group. There was also a reduction in variability in the CAS group compared to the third group, although this was not statistically significant. It is concluded that the use of computer navigation helped the surgeon to place the cup component with less variability of the abduction angle, and, more importantly, we found that no cups were placed in the more extreme positions (outliers).
Real-Time Face Identification via CNN and Boosted Hashing Forest (2016)

The family of real-time face representations is obtained via Convolutional Network with Hashing Forest (CNHF). We learn the CNN, then transform CNN to the multiple convolution architecture and finally learn the output hashing transform via new Boosted Hashing Forest (BHF) technique. This BHF generalizes the Boosted SSC approach for hashing learning with joint optimization of face verification and identification. CNHF is trained on CASIA-WebFace dataset and evaluated on LFW dataset. We code the output of single CNN with 97% on LFW. For Hamming embedding we get CBHF-200 bit (25 byte) code with 96.3% and 2000-bit code with 98.14% on LFW. CNHF with 2000×7-bit hashing trees achieves 93% rank-1 on LFW relative to basic CNN 89.9% rank-1. CNHF generates templates at the rate of 40+ fps with CPU Core i7 and 120+ fps with GPU GeForce GTX 650.
Full-Text Indexing Based on Lexical Relations (1989)

In contrast to other kinds of libraries, software libraries need to be conceptually organized. When looking for a component, the main concern of users is the functionality of the desired component; implementation details are secondary. Software reuse would be enhanced with conceptually organized large libraries of software components. In this paper, we present GURU, a tool that allows automatical building of such large software libraries from documented software components. We focus here on GURU's indexing component which extracts conceptual attributes from natural language documentation. This indexing method is based on words' co-occurrences. It first uses EXTRACT, a co-occurrence knowledge compiler for extracting potential attributes from textual documents. Conceptually relevant collocations are then selected according to their resolving power, which scales down the noise due to context words. This fully automated indexing tool thus goes further than keyword-based tools in the understanding of a document without the brittleness of knowledge based tools. The indexing component of GURU is fully implemented, and some results are given in the paper.
Comparative Study of Active Thermography Techniques for the Nondestructive Evaluation of Honeycomb Structures (2009)

In this article, the theoretical and experimental aspects of three active thermography approaches: pulsed thermography (PT), lock-in thermography (LT), and vibrothermography (VT), are discussed in relation to the nondestructive evaluation (NDE) of honeycomb sandwich structures. For this purpose, two standard specimens with simulated defects (delaminations, core unbonds, excessive adhesive, and crushed core) were tested, and results were processed, examined, and compared. As will be pointed out, the similarities and differences between these active approaches allow conclusions to be made about the most suitable approach for a particular application. In addition, results from NDE inspection by X-rays and c-scan ultrasounds are provided and discussed for reference.
Soluble CD14 Levels in the Serum, Synovial Fluid, and Cerebrospinal Fluid of Patients with Various Stages of Lyme Disease (2000)

Levels of circulating soluble CD14 (sCD14) in patients with various stages of Lyme disease (LD) were examined. Patients with early or untreated late LD had significantly higher levels of sCD14 than did healthy controls (P=.0001 and .0007, respectively); levels returned to normal within 3 months after antibiotic therapy. Patients with persistent posttreatment symptoms of LD had sCD14 levels equivalent to those of healthy controls. Differences in the serum sCD14 levels in patients with various stages of LD are likely to be directly correlated with differences in bacterial burden, suggesting that posttreatment symptoms may not require continued presence of the organism. sCD14 levels in the cerebrospinal fluid (CSF) of patients with any stage of LD were no different from those of control subjects. Levels of synovial fluid sCD14 from patients with Borrelia burgdorferi in their joints were elevated, compared with levels in normal serum, and may play a role in the pathogenesis of arthritis.
MESH: distributed error recovery for multimedia streams in wide-area multicast networks (2002)

This paper addresses support for multi-party multimedia applications delivered across datagram wide-area networks such as the Internet. Our approach is to develop a novel retransmission protocol framework, MESH, that protects delay-sensitive multicast data streams against most network errors and delay variations. The MESH approach partitions the multicast group into subgroups, elects subgroup managers called active receivers, and localizes error recovery between active receivers. Novel features of our protocol include an explicit model for delay-sensitive retransmission, run-time evaluation at an active receiver to determine its retransmission partner, and the ability to handle multiple multicast data sources without building a per-source control framework. To evaluate the performance and network costs of MESH, a wide-area network simulation of digital video distribution is constructed and studied over a range of network loss rates. Simulation experiments show that both MESH and an alternative scheme, end-to-end forward error correction, provide excellent error control with MESH incurring significantly less network overhead.
OntBot: Ontology based chatbot (2011)

A new ontology based approach is proposed to model and operate chatbots (OntBot). OntBot uses appropriate mapping technique to transform ontologies and knowledge into relational database and then use that knowledge to drive its chats. The proposed approach overcomes a number of traditional chatbots drawbacks including: the need to learn and use chatbot specific language such as AIML, high botmaster interference, and the use of non-matured technology. OntBot has the additional power of easy users interactions using their natural language, and the seamless support of different application domains. This gives the proposed approach a number of unique scalability and interoperability properties that are going to be evaluated in future phases of this research project.
Analysis of temporal evolution of quantum dot surface chemistry by surface-enhanced Raman scattering (2016)

Temporal evolution of surface chemistry during oxidation of silicon quantum dot (Si-QD) surfaces were probed using surface-enhanced Raman scattering (SERS). A monolayer of hydrogen and chlorine terminated plasma-synthesized Si-QDs were spin-coated on silver oxide thin films. A clearly enhanced signal of surface modes, including Si-Clx and Si-Hx modes were observed from as-synthesized Si-QDs as a result of the plasmonic enhancement of the Raman signal at Si-QD/silver oxide interface. Upon oxidation, a gradual decrease of Si-Clx and Si-Hx modes, and an emergence of Si-Ox and Si-O-Hx modes have been observed. In addition, first, second and third transverse optical modes of Si-QDs were also observed in the SERS spectra, revealing information on the crystalline morphology of Si-QDs. An absence of any of the abovementioned spectral features, but only the first transverse optical mode of Si-QDs from thick Si-QD films validated that the spectral features observed from Si-QDs on silver oxide thin films are originated from the SERS effect. These results indicate that real-time SERS is a powerful diagnostic tool and a novel approach to probe the dynamic surface/interface chemistry of quantum dots, especially when they involve in oxidative, catalytic, and electrochemical surface/interface reactions.

Observation of Quantum Fluctuations of Charge on a Quantum Dot (1999)

We have incorporated an aluminum single electron transistor directly into the defining gate structure of a semiconductor quantum dot, permitting precise measurement of the dot charge. Voltage biasing a gate draws charge from a reservoir into the dot through a single point contact. The dot charge increases continuously for large point contact conductance and in single electron steps with the contact nearly closed, and we measure the corresponding capacitance line shapes. The line shapes are not typical of lifetime or thermal broadening but fit well to predictions of perturbation theory.
Expression and secretion of neuroleukin/phosphohexose isomerase/maturation factor as autocrine motility factor by tumor cells. (1998)

The results obtained from fragmented protein microsequencing have suggested that autocrine motility factor (AMF), a tumor-secreted Mr 55,000 cytokine that regulates cell motility in vitro as well as invasion and metastasis in vivo, is the neuroleukin (NLK)/phosphohexose isomerase (PHI)/maturation factor (MF) polypeptide. Here, we cloned, sequenced, and studied the expression, secretion, and distribution of AMF/NLK/PHI/MF in neoplastic and their normal counterpart cells. Although both normal and neoplastic cells express the gene product, overexpression associated with selective secretion of the protein was observed only in tumor cells. The cDNA sequences of AMF/NLK/PHI/MF found in both human cancer and normal cells were found to be identical, suggesting that its secretion by neoplastic cells is independent of mutation or alternative splicing. Immunohistochemical visualization has depicted AMF/NLK/PHI/MF to be localized into tubular-like vesicles, diffusely distributed throughout the cytoplasm and not colocalized with any particular cytoskeletal network. Confocal microscopic imaging had shown a partial colocalization between AMF and its receptor (Mr 78,000 glycoprotein), especially on the malignant cell surface periphery. The results suggest that extracellular AMF activity may be a result of the product of intracellular cleavage of a precursor polypeptide, which is overexpressed and selectively secreted through a nonclassical secretory mechanism by neoplastic cells.
Surface delivery of tunable doses of BMP-2 from an adaptable polymeric scaffold induces volumetric bone regeneration (2016)

The rapid and effective bone regeneration of large non-healing defects remains challenging. Bioactive proteins, such as bone morphogenetic protein (BMP)-2, are proved their osteoinductivity, but their clinical use is currently limited to collagen as biomaterial. Being able to deliver BMP-2 from any other biomaterial would broaden its clinical use. This work presents a novel means for repairing a critical size volumetric bone femoral defect in the rat by combining a osteoinductive surface coating (2D) to a polymeric scaffold (3D hollow tube) made of commercially-available PLGA. Using a polyelectrolyte film as BMP-2 carrier, we tune the amount of BMP-2 loaded in and released from the polyelectrolyte film coating over a large extent by controlling the film crosslinking level and initial concentration of BMP-2 in solution. Using microcomputed tomography and quantitative analysis of the regenerated bone growth kinetics, we show that the amount of newly formed bone and kinetics can be modulated: an effective and fast repair was obtained in 1-2 weeks in the best conditions, including complete defect bridging, formation of vascularized and mineralized bone tissue. Histological staining and high-resolution computed tomography revealed the presence of bone regeneration inside and around the tube with spatially distinct organization for trabecular-like and cortical bones. The amount of cortical bone and its thickness increased with the BMP-2 dose. In view of the recent developments in additive manufacturing techniques, this surface-coating technology may be applied in combination with various types of polymeric or metallic scaffolds to offer new perspectives of bone regeneration in personalized medicine.
Real Time Foam Performance Testing (1993)

Real time automotive seat performance evaluations are now made possible by a new and unique computerized laboratory test. Most historic foam performance testing relies upon a post dynamic mode measurement of foam parameters after a relaxation period. The well-known ability of HR polyurethane foam to quickly recover lost properties suggests real time testing to be a better measure of the in-use performance of an automotive seating foam. The new test utilizes a hydraulically operated indentor foot to provide seat cushion loading under dynamic conditions, comparable to those of actual driver and passenger use. In a relatively short period of time, such as 8 to 9 hours, it is possible to record several real time changes in the performance of seats which are critical to their «in-use» comfort and safety qualities
A Package Technology for Miniaturized Field-Effect Transistor-Based Biosensors and the Sensor Array (2017)

In this study, a package technology has been developed for miniaturized filed-effect transistor (FET)-based biosensors. FETs were fabricated and diced as a 1 mm × 1 mm chip. The chip was then embedded in a plastic substrate and has a coplanar surface with that of the substrate. Photolithography followed by metal deposition and lift-off process was conducted to create metal lines, which connect the FET and extend to the edge of the plastic substrate. The FET-embedded plastic substrate was then engraved by laser to form a typical micro SD card and then passivated by photoresist, leaving the source-drain channel and the gate electrode open, followed by bonding a microfluidic channel made of PMMA. The packaged FET was tested in air and in buffer solution to confirm the well electrical isolation between metal interconnects and the solution, and the successful liquid flowing in the microfluidic channel. A FET sensor array was also made by embedding 8 FET chips into one plastic substrate with the same process. This package technology can largely reduce the cost of the sensor due to the very small size of the FET chip. The sensor chips can also be arbitrarily positioned into one plastic substrate to fit with multiple microfluidic channels, leading to great flexibility in the design of the sensor array. The result has shown a promising 2D system-in-package technology for sensor applications.
Radiation Energy Conversion in Space (1978)

Topics discussed at the third NASA conference on radiant energy conversion are reviewed. The unconcentrated-photovoltaic-generation version of a solar power satellite is described, noting that it will consist of a 21.3 x 5.3-sq-km silicon-solar-cell array expected to provide 17 Gw of electrical power, with 1 km in diam transmitters oriented to beam 2.45 GHz microwave power to two receiving/rectifying 'rectennas' on earth. The Solares space-energy-system concept, designed for providing a large fraction of the world's energy needs at costs comparable to those of future coal/nuclear alternative, is considered, as are subsystems for improving the economics of the solar power satellite. A concept proposing the use of relativistic-electron-storage rings for electron-beam energy transmission and storage, and a report on the production of a high temperature plasma with concentrated solar radiation are taken into account. Laser-conversion systems, including the direct-solar-pumped space laser, and the telec-powered spacecraft, are discussed.
Intracellular Events in the “Selective” Transport of Lipoprotein-derived Cholesteryl Esters (1996)

The current study utilizes human, apoE-free high density lipoprotein reconstituted with a highly specific fluorescent-cholesteryl ester probe to define the initial steps and regulatory sites associated with the "selective" uptake and intracellular itinerary of lipoprotein-derived cholesteryl esters. Bt2cAMP-stimulated ovarian granulosa cells were used as the experimental model, and both morphological and biochemical fluorescence data were obtained. The data show that cholesteryl ester provided through the selective pathway is a process which begins with a temperature-independent transfer of cholesteryl ester to the cell's plasma membrane. Thereafter transfer of the lipid proceeds rapidly and accumulates prominently in a perinuclear region (presumed to be the Golgi/membrane sorting compartment) and in lipid storage droplets of the cells. The data suggest that lipid transfer proteins (or other small soluble proteins) are not required for the intracellular transport of the cholesteryl esters, nor is an intact Golgi complex or an intact cell cytoskeleton (although the transfer is less efficient in the presence of certain microtubule-disrupting agents). The intracellular transfer of the cholesteryl esters is also somewhat dependent on an energy source in that a glucose-deficient culture medium or a combination of metabolic inhibitors reduces the efficiency of the transfer. A protein-mediated event may be required for cholesteryl ester internalization from the plasma membrane, in that N-ethylmaleimide dramatically blocks the internalization phase of the selective uptake process. Taken together these data suggest that the selective pathway is a factor-dependent, energy-requiring cholesteryl ester transport system, in which lipoprotein-donated cholesteryl esters probably flow through vesicles or intracellular membrane sheets and their connections, rather than through the cell cytosol.
Stability of FK 506 in Whole Blood Samples (1995)

The effect of storage time and temperature on the stability of FK 506 in patient blood samples and quality control samples was assessed with the Abbott IMx microparticle enzyme immunoassay. Blood FK 506 concentrations measured at days 0, 2, 3, 4, 7, and 14 were stable at room (22 degrees C), refrigerator (4 degrees C), and freezer (-70 degrees C) temperatures for the 2-week study period. Patient samples stored at -70 degrees C for almost 1 year and then reanalyzed for FK 506 were also found to be stable.

Fuzzy logic based railway track condition monitoring system (2013)

In recent years, the need to improve the quality and comfort of railway passengers, there has been increased demands to reduce the level of noise and vibration, experienced during travel. Different researches have focused on reducing the level of vibration. Track irregularities are the main causes of vibration and thus carefully monitor the parameter to improve the ride quality. Vibration may arise vertically and laterally, in this vertical vibration is higher. In this paper, we proposed a new method called Fuzzy Track Monitoring System (FTMS) for estimating the irregularities present in the railway track at running time. The vibration sensor is mounted on the axel box and the bogie of the train for measuring the acceleration in the lateral and vertical directions. The system automatically tracks the location of vibration and sends it to the central office. The performance of proposed approach was studied and it proves that the proposed approach is capable for real time measurements.
