CAPITELLAR HEMIARTHROPLASTY SIGNIFICANTLY ALTERS RADIOCAPITELLAR CONTACT MECHANICS (2012)

Purpose Capitellum hemiarthroplasty is an emerging concept. The current metallic capitellar implants have spherical surface shapes, but the native capitellum is not spherical. This study evaluated the effect of capitellar implant shape on the contact mechanics of the radiocapitellar joint when articulating with the native radial head. Method Eight paired radii and humeri were potted in a custom jig. Articular casts were made with medium-viscosity resin while 85 N of axial load was applied to the reduced radiocapitellar joint at 0, 45, and 90 of elbow flexion, and at neutral, 50 pronation and 50 supination at each flexion angle. The native radiocapitellar articulation was compared to capitellar hemiarthroplasties of two surface designs (anatomical and spherical). Contact area and shape (circularity) were determined. Circularity was defined as the ratio of the minor axis and major axis of the shape. Results At 0 of flexion, the anatomical hemiarthroplasty had a contact area of 52–70% that of the native articulation (p=0.03), while the spherical hemiarthroplasty had a contact area 40–42% that of the native articulation (p=0.003). At 45 of flexion, both hemiarthroplasties displayed contact area 0.05). The contact shape of the native radiocapitellar articulation was ellipsoid, with a range of circularity values from 0.530.19 to 0.720.16, depending on the flexion and rotation angle. At 0 and 90 flexion, there was no difference in contact shape between the native articulation, the anatomical, or spherical implant (p>0.05). At 45 flexion, the anatomical implant contact was less circular than either the native articulation (p=0.006) or the spherical hemiarthroplasty (p=0.002). Conclusion Metallic capitellar hemiarthroplasty causes a significant reduction in contact area at 0 and 45 elbow flexion, which may have important long-term implications for wear of the radial head cartilage. This reduction is similar to previous reports, which have evaluated the effect of metallic radial head hemiarthroplasty articulating with the native capitellum. More compliant alternative materials are needed to improve the contact characteristics of metallic capitellar hemiarthroplasties. Although the anatomical hemiarthroplasty was created from a detailed morphological study of the capitellum, the anatomical implant failed to completely reproduce the contact native shape. The theoretical advantages of a more anatomical capitellar implant shape may not be realized clinically, suggesting a spherical implant, which is easier to manufacture and implant, may be adequate for patient application. Further studies are required to delineate the effect of this altered contact morphology on implant function and radial head wear in-vivo.
Vehicle Pure Yaw Moment control using differential tire slip (2009)

Direct yaw moment control generated by differential friction forces on an axle has been proved to be effective in improving vehicle lateral yaw stability and in enhancing handling performance. It consists of two levels of control tasks: calculating a yaw moment command at vehicle level and regulating the tire slip to deliver the moment at wheel level. Advanced powertrain with electrical in-wheel-motor makes fast wheel level control possible. This paper proposes an adaptive tire slip controller for pure yaw moment generation, which yields the maximal axle yaw moment by asymmetric axle friction force with no effect on vehicle longitudinal speed. Since the maximal friction is limited by the tire-road contact, control constraints at various vehicle speeds and on different surface conditions has to be taken into account. This algorithm can generate the optimal longitudinal slip ratio at the presence of lateral tire force based on a 2D Modified-LuGre tire model. One major difficulty of such type controllers is the unknown surface condition. A nonlinear adaptive braking/traction torque control is proposed to regulate the tire slip ratio with the estimation of surface condition. Simulation studies show that feeding back the estimate into the slip control makes the delivered friction force and yaw moment adaptive to surface conditions.

Mechanical Fatigue of Bovine Cortical Bone Using Ground Reaction Force Waveforms in Running (2017)

Stress fractures are a common overuse injury among runners associated with the mechanical fatigue of bone. Several in vivo biomechanical studies have investigated specific characteristics of the vertical ground reaction force (vGRF) in heel-toe running and have observed an association between increased loading rate during impact and individuals with a history of stress fracture. The purpose of this study was to examine the fatigue behavior of cortical bone using vGRF-like loading profiles, including those that had been decomposed into their respective impact and active phase components. Thirty-eight cylindrical cortical bone samples were extracted from bovine tibiae and femora. Hydrated samples were fatigue tested at room temperature in zero compression under load control using either a raw (n = 10), active (n = 10), low impact (n = 10), or high impact (n = 8) vGRF profile. The number of cycles to failure was quantified and the test was terminated if the sample survived 105 cycles. Fatigue life was significantly greater for both impact groups compared to the active (p < 0.001) and raw (p < 0.001) groups, with all low impact samples and 6 of 8 high impact samples surviving 105 cycles. The mean (± SD) number of cycles to failure for the active and raw groups was 12,133±11,704 and 16,552±29,612, respectively. The results suggest that loading rates associated with the impact phase of a typical vGRF in running have little influence on the mechanical fatigue behavior of bone relative to loading magnitude, warranting further investigation of the mechanism by which increased loading rates are associated with stress fracture.
Audio driven facial animation for audio-visual reality (2001)

In this paper, we demonstrate a morphing based automated audio driven facial animation system. Based on an incoming audio stream, a face image is animated with full lip synchronization and expression. An animation sequence using optical flow between visemes is constructed, given an incoming audio stream and still pictures of a face speaking different visemes. Rules are formulated based on coarticulation and the duration of a viseme to control the continuity in terms of shape and extent of lip opening. In addition to this new viseme-expression combinations are synthesized to be able to generate animations with new facial expressions. Finally various applications of this system are discussed in the context of creating audio-visual reality.
Calibrating ink spreading curves by optimal selection of tiles from printed color images (2012)

The Yule-Nielsen modified spectral Neugebauer model (YNSN) enables predicting reflectance spectra from ink surface coverages of halftones. To provide an improved prediction accuracy, this model is enhanced with an ink spreading model accounting for ink spreading in all superposition conditions (ISYNSN). As any other spectral reflection prediction model, the ISYNSN model is conceived to predict the reflection spectra of color-constant patches. Instead of color-constant patches, we investigate if tiles located within color images can be accurately predicted and how they can be used to facilitate the calibration of the ink spreading model. We detail an algorithm to automatically select image tiles as uniform as possible from color images by relying on their CMY or CMYK pixel values. The tile selection algorithm incorporates additional constraints relying on surface coverages of the inks. We demonstrate that an ink spreading model calibrated with as few as 5 to 10 optimally chosen image tiles allows the corresponding YNSN model to provide accurate spectral predictions.
Fault Detection, Isolation and Recovery (FDIR) Portable Liquid Oxygen Hardware Demonstrator (2011)

The Fault Detection, Isolation and Recovery (FDIR) hardware demonstration will highlight the effort being conducted by Constellation's Ground Operations (GO) to provide the Launch Control System (LCS) with system-level health management during vehicle processing and countdown activities. A proof-of-concept demonstration of the FDIR prototype established the capability of the software to provide real-time fault detection and isolation using generated Liquid Hydrogen data. The FDIR portable testbed unit (presented here) aims to enhance FDIR by providing a dynamic simulation of Constellation subsystems that feed the FDIR software live data based on Liquid Oxygen system properties. The LO2 cryogenic ground system has key properties that are analogous to the properties of an electronic circuit. The LO2 system is modeled using electrical components and an equivalent circuit is designed on a printed circuit board to simulate the live data. The portable testbed is also be equipped with data acquisition and communication hardware to relay the measurements to the FDIR application running on a PC. This portable testbed is an ideal capability to perform FDIR software testing, troubleshooting, training among others.
Synthesis of lateral chloro substituted biphenyl carboxylic acids and phenols for optically active esters (1998)

Abstract The new pathway for the synthesis of lateral chloro substituted biphenyl carboxylic acids and phenols has been worked out. 3-Aryl-6-alkylcyclohex-2-en-1-ones arriving from the Michael type condensation of Mannich salts with the corresponding 2-alkylacetoacetic esters were used as the key starting compounds. The prepared carboxylic acids and phenol were applied as semiproducts for the synthesis of variety of the optically active esters. The phase transition temperatures for the prepared compounds are determined.
Substrate Misorientation, Multi‐Quantum‐Barrier, and Thermal Annealing Effects in MgZnSSe and ZnCdSe Compounds and Blue‐Green II‐VI Light Emitting Devices (1995)

Abstract Multi‐quantum‐barrier (MQB), substrate misorientation, and thermal annealing effects are investigated in MgZnSSe and ZnCdSe compounds and blue‐green II‐VI light emitting devices. The heterobarrier enhancement of MgZnSSe/ZnSe MQBs is analyzed to be 100 meV, using the experimental band offset of Δ E c ≈ 0.65Δ E g . By use of MQB effect, low threshold current density operation below 1 kA/cm 2 can be expected in 480 nm blue emission ZnCdSe/MgZnSSe lasers. For N‐doped MgZnSSe grown on intentionally misoriented GaAs substrates, the decreased net acceptor concentration with misorientation angle is discussed, concluding that the enhanced sulfur incorporation by substrate misorientation plays some role in degradation. It is clarified that ZnSe and ZnSSe are not degraded up to 400°C annealing, while MgZnSSe is even at 350 to 400°C annealing. The light output of ZnCdSe/ZnSe MQW LEDs is enhanced by thermal annealing (325°C, 7 min), by a factor of three.
PER prediction for convolutionally coded MIMO OFDM systems &#x2014; An analytical approach (2012)

Packet error rate (PER) prediction for multiple-input multiple-output (MIMO) orthogonal frequency-division multiplexing (OFDM) systems is important to link adaptation. However, since the existing prediction methods require curve fitting and parameter calibration for each transmission scheme, they are actually not practical as the number of scheme increases. This paper presents a purely analytical approach to PER prediction for rate-compatible punctured convolutional (RCPC) with bit-interleaved coded modulation (BICM) MIMO OFDM systems based on the analysis of pairwise error probability (PEP) and the transfer functions of the codes. The accuracy of the proposed method is comparable with which resulting from other heuristic methods.

Altimetric performance of the GEROS experiment at the ISS (2016)

The GNSS rEflectometry, Radio Occultation and Scatterometry onboard the International Space Station (GEROS-ISS) is an innovative experiment for climate research, proposed in 2011 within a call of the European Space Agency (ESA) for installation at the ISS. This international proposal was the only one selected for further studies by ESA out of ~25 submitted ones. In this work, an updated assessment of the instrument performance for the near-nadir altimetry (GNSS-R) mode and scatterometry is assessed, including the effect of the inter-modulation signals, and the expected degradation due to presence of radio-frequency interference coming from DME/TACAN systems. These results correspond to the study lead by Airbus Defence and Space-Spain, one of the two parallel Phase A studies conducted by ESA.
Glutaric acidemia type II. Heterogeneity in beta-oxidation flux, polypeptide synthesis, and complementary DNA mutations in the alpha subunit of electron transfer flavoprotein in eight patients. (1992)

We studied metabolic, polypeptide and genetic variation in eight glutaric acidemia type II (GA II) patients with electron transfer flavoprotein (ETF) deficiency. As measured by 3H-fatty acid oxidations in fibroblasts, beta-oxidation pathway flux correlated well with clinical phenotypes. In six patients with severe neonatal onset GA II, oxidation of [9,10(n)-3H]-palmitate ranged from 2% to 22% of control and of [9,10(n)-3H]myristate, from 2% to 26% of control. Of two patients with late onset GA II, one had intermediate residual activities with these substrates and the other normal activities. Radiolabeling and immunoprecipitation studies revealed that three of the six neonatal onset GA II patients had greatly diminished or absent alpha- and beta-ETF subunits, consistent with a failure to assemble a stable heterodimer. Another neonatal onset patient showed normal synthesis of beta-ETF but decreased synthesis of alpha-ETF. Two neonatal onset and two late onset GA II patients showed normal synthesis of both subunits. Analysis of the pre-alpha-ETF coding sequence revealed seven different mutations in the six patients with neonatal onset GA II. The most common mutation was a methionine for threonine substitution at codon 266 found in four unrelated patients, while all the other mutations were seen in single patients. No mutations were detected in the two patients with late onset GA II.
Atypical Multidrug Resistance: Breast Cancer Resistance Protein Messenger RNA Expression in Mitoxantrone-Selected Cell Lines (1999)

Overexpression of BCRP mRNA is frequently observed in multidrug-resistant cell lines selected with mitoxantrone, suggesting that BCRP is likely to be a major cellular defense mechanism elicited in response to exposure to this drug. It is likely that BCRP is the putative "mitoxantrone transporter" hypothesized to be present in these cell lines.

IL-33 mediates multi-walled carbon nanotube (MWCNT)-induced airway hyper-reactivity via the mobilization of innate helper cells in the lung (2012)

Allergic asthma is a chronic inflammatory disorder of the airway associated with bronchial obstruction, airway hyper-reactivity (AHR), and mucus production. The epithelium may direct and propagate asthmatic-like responses. Central to this theory is the observation that viruses, air pollution, and allergens promote epithelial damage and trigger the generation of IL-25, IL-33, and TSLP via innate pathways such as TLRs and purinergic receptors. Similarly, engineered nanomaterials promote a Th2-associated pathophysiology. In this study, we tested the hypothesis that instillation of multi-walled carbon nanotubes (MWCNT) impair pulmonary function in C57Bl/6 mice due to the development of IL-33-dependent Th2-associated inflammation. MWCNT exposure resulted in elevated levels of IL-33 in the lavage fluid (likely originating from airway epithelial cells), enhanced AHR, eosinophil recruitment, and production of Th2-associated cytokines and chemokines. Moreover, these events were dependent on IL-13 signaling and the IL-33/ST2 axis, but independent of T and B cells. Finally, MWCNT exposure resulted in the recruitment of innate lymphoid cells. Collectively, our data suggest that MWCNT induce epithelial damage that results in release of IL-33, which in turn promotes innate lymphoid cell recruitment and the development of IL-13-dependent inflammatory response.

Flow-induced thermal effects on spatial DNA melting (2008)

Continuous-flow temperature gradient microfluidics can be used to perform spatial DNA melting analysis. To accurately characterize the melting behavior of PCR amplicon across a spatial temperature gradient, the temperature distribution along the microfluidic channel must be both stable and known. Although temperature change created by micro-flows is often neglected, flow-induced effects can cause significant local variations in the temperature profile within the fluid and the closely surrounding substrate. In this study, microfluidic flow within a substrate with a quasi-linear temperature gradient has been examined experimentally and numerically. Serpentine geometries consisting of 10 mm long channel sections joined with 90 degrees and/or 180 degrees bends were studied. Infrared thermometry was used to characterize the surface temperature variations and a 3-D conjugate heat transfer model was used to predict interior temperatures for multiple device configurations. The thermal interaction between adjacent counter-flow channel sections, which is related to their spacing and substrate material properties, contributes significantly to the temperature profile within the microchannel and substrate. The volumetric flow rate and axial temperature gradient are directly proportional to the thermal variations within the device, while these flow-induced effects are largely independent of the cross-sectional area of the microchannel. The quantitative results and qualitative trends that are presented in this study are applicable to temperature gradient heating systems as well as other microfluidic thermal systems.
Preparation and In Vivo Studies of a New Drug Delivery System (1984)

Polyhexylcyanoacrylate nanoparticles have been prepared with vincamine as the model drug. These particles had an average size of 200 nm and adsorbed approximately 43% of vincamine. The adsorption of vincamine to nanoparticles modified the distribution of vincamine in tissues. After iv injection the distribution volumes were increased in comparison with an aqueous solution of drug. In comparison with an aqueous solution of drug, the absolute bioavailability of vincamine was also increased after an oral administration of nanoparticles.
