Improvement of Cycle Performance of Lithium-Ion Batteries at Elevated Temperature of 60oC Using Graphite Coated with Metal Oxide (2013)

Improvement of cycle performance at 60 o C by using SiO x modified graphite has been investigated. A main degradation mode of LiFePO 4 /Graphite cell was investigated. In LiFePO 4 and graphite, the degradation of LIB is mainly due to the loss of Li + , and probably not due to the damage to active material analyzed by XRD pattern and charge-discharge curve. To suppress the loss of Li + , surface modification was examined. SEI formation on Si film is suppressed by modification of SiO x and AlO x . SEI thickness on the Si thin film coated with metal oxide (MO x ) has critical influence on resistance of MO x . In the cyclic voltammetry, the intensity of the charge peak at 0.9V during the first charge indicates decomposition of an electrolyte. In SiO x modified graphite, the capacity estimated from 1 V to 0.7 V is decreased compared to the unmodified graphite. Cycle performance was improved by SiO x modified graphite.
Modeling and Diagnostics of Heart Assist Devices (2009)

Presented are online adaptive models for ventricular assist devices (VADs). Such devices are used to assist failing hearts or in the case considered here to create a total artificial heart. Adaptive models are developed to estimate cardiac output (CO) and power consumption of the VAD. These parameters are critical to physicians during patient care as well as in diagnosing VAD operation. The online adaptive nature of these models will be used to estimate effective blood viscosity in real-time and to create a mechanism whereby specific VAD diagnostics, important to robust CO delivery, can be identified, isolated and estimated. The experiments conducted were ex-vivo in a mock circulation loop in which the precise nature of the working fluid properties can be controlled and measured.
System and method for monitoring a reactor system using optical fiber based sensors (2023)

A method of monitoring operation of a reactor system includes causing a chemical reaction to occur within an assembly of the reactor system, and measuring a chemical composition of one or more reactants of the chemical reaction with spatial resolution at a plurality of points along a path within the assembly using a sensor system structured to implement distributed sensing. The sensor system includes an optical fiber sensing member provided at least partially within the assembly, wherein the optical fiber sensing member comprises a functionalized optical fiber based sensor device structured to exhibit a change in one or more optical properties in response to changes in the chemical composition of the one or more reactants.
Chemically Imidized Polyimide as an Alignment Material for Liquid Crystal Displays (1998)

Abstract We have characterized a chemically imidized polyimide LARC‐CP1 newly synthesized by NASA as a low‐temperature‐processing alignment material for liquid crystal displays. Using low‐temperature boiling solvents, we havedeveloped a technique of cell coating that leads to a uniform planar director orientation with a pretilt angle that can be controlled in the range 0–7 degrees. Dependencies of the pretilt angle, anchoring energy coefficient, surface topography and voltage holding ratio on the type of solvent and conditions of processing(temperature, rubbing strength, etc.) have been explored.
Scalable Adaptive Stochastic Optimization Using Random Projections (2016)

Adaptive stochastic gradient methods such as AdaGrad have gained popularity in particular for training deep neural networks. The most commonly used and studied variant maintains a diagonal matrix approximation to second order information by accumulating past gradients which are used to tune the step size adaptively. In certain situations the full-matrix variant of AdaGrad is expected to attain better performance, however in high dimensions it is computationally impractical. We present Ada-LR and RadaGrad two computationally efficient approximations to full-matrix AdaGrad based on randomized dimensionality reduction. They are able to capture dependencies between features and achieve similar performance to full-matrix AdaGrad but at a much smaller computational cost. We show that the regret of Ada-LR is close to the regret of full-matrix AdaGrad which can have an up-to exponentially smaller dependence on the dimension than the diagonal variant. Empirically, we show that Ada-LR and RadaGrad perform similarly to full-matrix AdaGrad. On the task of training convolutional neural networks as well as recurrent neural networks, RadaGrad achieves faster convergence than diagonal AdaGrad.
Preparation of a Polyethylene Latex by Catalytic Hydrogenation of a Polybuta‐1,4‐diene‐Based Dispersion (2005)

Abstract Summary: Fully linear polyethylene‐based latexes have been prepared by the hydrogenation of polybuta‐1,4‐diene dispersions. The latter were synthesized via dispersion ring‐opening metathesis polymerization of cycloocta‐1,5‐diene, and hydrogenated using RuCl 2 (PPh 3 ) 3 as catalyst, without any further treatment. A high hydrogenation efficiency was achieved as demonstrated by different techniques including DSC, and 1 H NMR and FT‐IR spectroscopy. The hydrogenation process could be carried out without detrimental effect on particle size and colloidal stability as evidenced by optical microscopy and light scattering analysis.

Titanium particles suppress expression of osteoblastic phenotype in human mesenchymal stem cells (2002)

Long-term stability of arthroplasty prosthesis depends on the integration between osseous tissue and the implant biomaterial. Integrity of the osseous tissue requires the contribution of mesenchymal stem cells and their continuous differentiation into an osteoblastic phenotype. This study aims to investigate the hypothesis that exposure to wear debris particles derived from orthopaedic biomaterials affects the osteoblastic differentiation of human mesenchymal stem cells (hMSC). Upon in vitro culture in the presence of osteogenic supplements (OS), we observe that cultures of hMSCs isolated from femoral head bone marrow are capable of osteogenic differentiation, expressing alkaline phosphatase, osteocalcin, and bone sialoprotein (BSP), in addition to producing collagen type I and BSP accompanied by extracellular matrix mineralization. Exposure of OS-treated hMSCs to submicron commercially pure titanium (cpTi) particles suppresses BSP gene expression, reduces collagen type I and BSP production, decreases cellular proliferation and viability, and inhibits matrix mineralization. In comparison, exposure to zirconium oxide (ZrO2) particles of similar size did not alter osteoblastic gene expression and resulted in only a moderate decrease in cellular proliferation and mineralization. Confocal imaging of cpTi-treated hMSC cultures revealed patchy groups of cells displaying disorganized cytoskeletal architecture and low levels of extracellular BSP. These in vitro findings suggest that chronic exposure of marrow cells to titanium wear debris in vivo may contribute to decreased bone formation at the bone/implant interface by reducing the population of viable hMSCs and compromising their differentiation into functional osteoblasts. Understanding the nature of hMSC bioreactivity to orthopaedic wear debris should provide additional insights into mechanisms underlying aseptic loosening.

Power amplifier linearization technique with IQ imbalance and crosstalk compensation for broadband MIMO-OFDM transmitters (2011)

The design of predistortion techniques for broadband multiple input multiple output-OFDM (MIMO-OFDM) systems raises several implementation challenges. First, the large bandwidth of the OFDM signal requires the introduction of memory effects in the PD model. In addition, it is usual to consider an imbalanced in-phase and quadrature (IQ) modulator to translate the predistorted baseband signal to RF. Furthermore, the coupling effects, which occur when the MIMO paths are implemented in the same reduced size chipset, cannot be avoided in MIMO transceivers structures. This study proposes a MIMO-PD system that linearizes the power amplifier response and compensates nonlinear crosstalk and IQ imbalance effects for each branch of the multiantenna system. Efficient recursive algorithms are presented to estimate the complete MIMO-PD coefficients. The algorithms avoid the high computational complexity in previous solutions based on least squares estimation. The performance of the proposed MIMO-PD structure is validated by simulations using a two-transmitter antenna MIMO system. Error vector magnitude and adjacent channel power ratio are evaluated showing significant improvement compared with conventional MIMO-PD systems.
Overexpression of Class III β-Tubulin Predicts Good Response to Taxane-Based Chemotherapy in Ovarian Clear Cell Adenocarcinoma (2009)

Taxane-based chemotherapy was effective for patients with ovarian clear cell adenocarcinomas who were positive for beta-tubulin III but not for those who were negative for these proteins.
Thermodynamic Calculation of the VPE Growth of In1-xGaxAs by the Trichloride Method (1984)

A method of computation developed for analysing the equilibrium state of a multicomponent system, has been extended to the epitaxial growth of In 1- x Ga x As performed by the trichloride (AsCl 3 ) method. The general features of the equilibrium partial pressures are found to be similar to those of the hydride system. The deposition diagram is computed as a function of the input mole ratio, and the effect of the growth parameters on the composition of the deposit is discussed in comparison with other techniques. It is shown that the thermodynamic model can explain the slow growth rates observed in both the trichloride and the single flat-temperature zone methods.
Development of ruthenium(ii) complexes as topical antibiotics against methicillin resistant Staphylococcus aureus (2013)

A series of ruthenium(II) bis(2,2'-bipyridyl) complexes containing N-phenyl-substituted diazafluorenes (Ru-C1, Ru-C6, Ru-C7 and Ru-F) was synthesized and their potential antibacterial activity against methicillin resistant Staphylococcus aureus (MRSA) was investigated. The Ru-C7 complex showed significant improvement in both minimum inhibitory concentration (MIC, 6.25 μg mL(-1)) and minimum bactericidal concentration (MBC, 25 μg mL(-1)) towards MRSA when compared with those of methicillin (positive control) (MIC = 25 μg mL(-1) and MBC = 100 μg mL(-1)). The Ru-C7 complex possessed much stronger antibacterial effects than the Ru-C6 complex (MIC, 25 μg mL(-1), MBC, >100 μg mL(-1)). Both Ru-C6 and Ru-C7 complexes were also demonstrated to be biologically safe when tested on normal human skin keratinocytes.
Synthesis and Biophysical Properties of Phosphorodiamidate Piperidino Oligomers (2023)

We report the synthesis of piperidino nucleoside phosphoramidates functionalized with uracil, cytosine, guanine, and adenine and their incorporation into oligomers. High-performance liquid chromatography analyses demonstrated that a phosphorodiamidate piperidino oligomer (PPO) is more lipophilic than a phosphorodiamidate morpholino oligomer (PMO) of the same tetrameric sequence. A PMO containing piperidino residues formed duplexes with both DNA and RNA, and the PPO had higher stability at endosomolytic pH and higher hydrophobicity than the PMO.
ANU/ACSys TREC-5 Experiments. (1996)

A number of experiments conducted within the framework of the TREC-6 conference and using a completely re-engineered version of the PArallel Document Retrieval Engine (PADRE97) are reported. Passage-based pseudo relevance feedback combined with a variant of City University&amp;apos;s Okapi BM25 scoring function achieved best average precision, best recall and best precision@20 in the Long-topic Automatic Adhoc category. The same basic method was used as the basis for successful submissions in the Manual Adhoc, Filtering and VLC tasks. A new BM25-based method of scoring concept intersections was shown to produce a small but significant gain in precision on the Manual Adhoc task while the relevance feedback scheme produced a significant improvement in recall for all of the Adhoc query sets to which it was applied. 1 Introduction The work reported here comprises a number of text retrieval experiments conducted within the framework of TREC-6 and addressing questions of interest in the following re...
Aging Related Changes in the Kinematics of Walking: A Potential Pathway to Changes in Cartilage Morphology (2012)

Age-related changes in spatio-temporal and sagittal plane walking mechanics are well documented [1, 2]. These changes along with age-related changes in muscle strength, muscle activation patterns and ligament stiffness [3] may also lead to changes in both rotational and translation motions at the knee. It has been suggested that alterations in the normal kinematics of the knee related to aging may be a contributing factor to the increased incidence of knee osteoarthritis (OA) with aging [4].
Ultra-dense, 1152-core, broadband multicore fiber link deployed in a metro network (2023)

We have designed, developed, and deployed the world's first ultra-dense space division-multiplexing multicore fiber link in a conduit of a metro network. In a 10-mm-diameter fiber optic-cable, 288 4-core multicore fibers are arranged in 24 200-µm spiderweb collapsible ribbons. The multicore fibers are fusion-spliced to 576 fanout devices which provide conventional single-core interfaces at patch panels at both ends of the link.
Abstract IA22: Tumor cells highjack diverse cellular processes to maintain redox balance (2020)

Abstract In aggressive sarcomas such as Ewing sarcoma (EwS) and osteosarcoma (OS), the single most powerful predictor of poor outcome is metastatic disease, highlighting the critical need to identify new factors driving metastasis in these diseases. Metastasis is widely regarded as a very inefficient process, likely due to diverse stress forms that can potentially cull premetastatic cancer cells during the metastatic cascade, including hypoxia in primary tumors, anoikis stress in the circulation, and increased oxidative stress at distant organs prior to colonization. Adaptation to such conditions requires rapid stress-alleviating plasticity to confer fitness for metastatic progression, but mechanisms remain elusive. Studies in our laboratory indicate that mitigation of oxidative stress, not only during local invasion at the primary tumor site but also in the circulation during dissemination, and potentially as part of colonization at distant sites, is critical for childhood sarcoma metastatic capacity. Indeed, EwS and OS cells appear to utilize many different strategies to maintain redox balance, such as the induction of antioxidant pathways involving NRF2 or through other mechanisms such as alterations in amino acid transporter systems to facilitate production of glutathione and other antioxidants via amino acid metabolism. Some of these pathways are transcriptionally regulated, such as by direct activation of EWS-ETS fusion targets, while others are regulated through rapid translational activation by pioneer translation factors such as YB-1. Examples of each of these processes will be discussed. Citation Format: Hai-Feng Zhang, Amal M. El Naggar, Hongwei Cheng, Wei Li, Dimiter S. Dimitrov, Poul H. Sorensen.

Generating High-Fidelity Images with Disentangled Adversarial VAEs and Structure-Aware Loss (2020)

While variational autoencoders (VAE) provide the theoretical basis for deep generative models, they often produce "blurry" images which is linked to their training objective. In this paper, we propose the "Sharpened Adversarial Variational Auto-Encoder" (AVAE-S) which uses an adversarial training mechanism to fine-tune the learned latent code vector of the VAE with a specialized objective function. The loss function is designed to uncover global structure as well as the local and high frequency features in VAE and leading to the smaller variance in the aggregated posterior and hence, reducing the blurriness of their generated samples. AVAE-S leverages the learned representations to the meaningful latent features by enforcing feature consistency between the model distribution and the target distribution leading to the sharpened output with better perceptual quality. Then, AVAE-S starts training a GAN network, which generator has been collapsed on the VAE's decoder, upon that learned latent code vector. Moreover, we augment the standard VAE's evidence lower bound objective function with other element-wise similarity measures. Our experiments show that AVAE-S achieves the state-of-the-art sample quality in the common MNIST and CelebA datasets. AVAE-S shares many of the good properties of the VAE (stable training, encoder-decoder architecture, nice latent manifold structure) while generating more realistic images, as measured by the sharpness score.
Spectral Collapse in Ensembles of Metamolecules (2010)

We report on the first direct experimental demonstration of a collective phenomenon in metamaterials: spectral line collapse with an increasing number of unit cell resonators (metamolecules). This effect, which is crucial for achieving a lasing spaser, a coherent source of optical radiation fuelled by coherent plasmonic oscillations in metamaterials, is linked to the suppression of radiation losses in periodic arrays. We experimentally demonstrate spectral line collapse at microwave, terahertz and optical frequencies.

On page 4585, D. E. Morse and co-workers report a biologically inspired, kinetically controlled, catalytic approach to synthesizing a new family of nanocrystalline platinum-based catalysts. A novel composite of multiwalled carbon nanotubes and carbon black serves as the matrix for the in situ nucleation and growth of the Pt nanocrystals, providing access to new combinations of porosity, mesoscale morphology, conductivity, and electrochemical activity for hydrogen oxidation.
CMOS ADCs Towards 100 GS/s and Beyond (2016)

The implementation of a 64x time-interleaved ADC in 32nm CMOS SOI is analyzed. Measurement results confirm 33 dB SNDR up to 19.9 GHz at 90 GS/s and 1.2V supply. Architecture details and analysis show insights into limitations and potentials of the chosen architecture. In par-ticular the input bandwidth is of concern for ADCs at more than 64 GS/s, as a larger number of sampling switches in-creases the parasitic load and reduces the input bandwidth. Insights on a simplified analysis of interleaver structures and existing solutions to bandwidth issues are highlighted and show a path to extend the sampling speed of CMOS ADCs beyond 100 GS/s.
An Isogenic Cell Line Panel for Sequence-based Screening of Targeted Anti-cancer Drugs (2021)

Summary We describe the creation and characterization of an isogenic cell line panel representing common cancer pathways, with multiple features optimized for high-throughput screening. More than 1,800 cell lines from three normal human cells were generated using CRISPR-technologies. Surprisingly, we discovered most of these lines did not result in complete gene inactivation, despite integration of sgRNA at the desired genomic site. However, a subset of the lines harbored true, biallelic disruptions of the targeted tumor suppressor gene, yielding a final panel of 100 well-characterize lines covering 19 pathways frequently subject to loss of function in cancers. This panel included genetic markers optimized for sequence-based ratiometric assays for drug-based screening assays. To illustrate the potential utility of this panel, we developed a multiplexed high-throughput screen that identified Wee1 inhibitor MK-1775 as a selective growth inhibitor of cells with inactivation of TP53 . These cell lines and screening approach should prove useful for researchers studying a variety of cellular and biochemical phenomena.
[Ablative methods for atrial fibrillation]. (2002)

Surgery and catheter-based ablation are the only curative approaches of atrial fibrillation. Since 1994, several ablative techniques based on 2 different concepts have been developed: modification of the substrate with long linear lesions to prevent fibrillation maintenance; and foci ablation to prevent fibrillation initiations. The latter is more frequently used now as the clustering of foci in pulmonary veins allows their isolation. The presence of numerous foci in some patients is responsible for more complex procedures and limits the success rate to 70%. In spite of this limit and because of a reasonable complication rate, this procedure compares favourably to His bundle ablation in young patients with symptomatic and drug-resistant paroxysmal atrial fibrillation.
Outgrowth of Bacillus megaterium Spores in the Presence of Nitrate and Ammonium Ions (1976)
