Rocket-borne Instrument for Observations of Near-Infrared and Far-Infrared Extended Astrophysical Emission (1994)

Abstract We give a detailed description of the design and flight performance of an instrument onboard the S-520-15 rocket of the Institute of Space and Astronautical Science. The instrument, consisting of a near-infrared spectrometer and a far-infrared photometer at the focus of a 10 cm liquid-helium cooled telescope, was designed to observe both the brightness and distribution of diffuse emission with high sensitivity. The rocket was successfully launched and the instrument observed near-infrared and far-infrared continuum emission, as well as [C II] 157.7 μm line emission from regions at high Galactic latitude. We also give a brief description of the design and performance of an onboard attitude control system.
Beyond Bernoulli (2017)

The application of the Bernoulli formulation results in a clinically significant overestimation of peak pressure drops because of approximation of blood flow as a single streamline. A corrected formulation that accounts for the cross-sectional profile of the blood flow is proposed and adapted to both cardiovascular magnetic resonance and echocardiographic data.

Differential Syringe Shield Effectiveness: Direct Comparisons Using SPECT and Planar Imaging (1993)

The use of syringe shields in clinical nuclear medicine has been employed to reduce occupational exposure. However, there is little, current, comparative literature available for the diverse number of products available. I performed single-photon emission computed tomography (SPECT) acquisition on four different shields, and the results were quantitated in order to evaluate the percentage of counts relative to an unshielded source and to the other models tested. All models tested were found to significantly reduce available counts, with the thin-wall shield producing the highest number of counts at the viewing port and the tungsten shield being the least effective overall. I concluded that the intrinsic differences between model design and materials utilized determines the overall efficiency, and that this information is important in light of both the as low as reasonably achievable (ALARA) principle and biological model concepts.
Thermally Modulated Insulin Release from Microgel Thin Films (2004)

We describe investigations of thermally triggered insulin release from poly(N-isopropylacrylamide-co-acrylic acid) microgel thin films prepared by layer-by-layer (LbL) polyelectrolyte assembly. The thermoresponsivity of these films was confirmed using light scattering techniques. Simultaneous monitoring of film collapse and insulin release kinetics shows that deswelling of the films is partially decoupled from macromolecule release and that release is mainly governed by partitioning effects. We hypothesize, however, that film thermoresponsivity plays an important role in that subjection to many thermal cycles enables the embedded peptide to solubilize and subsequently partition through film layers. Direct pulsatile and extended release studies confirm the capability of these films to release bursts of insulin over many cycles, and confirm that the magnitude of the release can be controlled based on film thickness. These insulin-impregnated films are extremely stable with the potential to release constant pulses of peptide for more than 1 month at a time.
Data Augmentation for Deep Neural Network Acoustic Modeling (2015)

This paper investigates data augmentation for deep neural network acoustic modeling based on label-preserving transformations to deal with data sparsity. Two data augmentation approaches, vocal tract length perturbation (VTLP) and stochastic feature mapping (SFM), are investigated for both deep neural networks (DNNs) and convolutional neural networks (CNNs). The approaches are focused on increasing speaker and speech variations of the limited training data such that the acoustic models trained with the augmented data are more robust to such variations. In addition, a two-stage data augmentation scheme based on a stacked architecture is proposed to combine VTLP and SFM as complementary approaches. Experiments are conducted on Assamese and Haitian Creole, two development languages of the IARPA Babel program, and improved performance on automatic speech recognition (ASR) and keyword search (KWS) is reported.
A Modeling and Simulation Platform for Robot Kinematics Aiming Visual Servo Control (2010)

A software platform RobSim for analysis and design of robotic systems that includes image capturing devices was presented. It was developed within the Matlab environment to simulate kinematics of robotic structures and it allows implementing control strategies in order to follow trajectories, perform tasks, etc. Thus it is very suitable to implement robotic experiments before dealing with the real system. The platform is based on basic units called primitives that assembled together can simulate any robotic structure. Being modular it is expandable, another advantage is the inclusion of a video capturing device that allows implementing vision-guided robotic experiments. The platform was used here to model and simulate fixed and mobile robots. Image- and position-based servoing schemes were implemented for a robotic manipulator with a single and a two-camera arrangement and
Functional Verification in an Interactive Symbolic IC Design Environment (1981)

This paper describes verification techniques that have been implemented as part of\nan interactive symbolic IC design system. Circuit analysis programs perform node\nextraction and gate decomposition. They generate both transistor and gate level\ncircuit desriptions which are used as input to a transistor level digital MOS timing\nsimulator. The extraction programs make use of an intermediate circuit description\nlanguage which captures both geometric placement and circuit connectivity.\nAll programs are written in the C programming language and run under the UNIX\noperating system. An example is included to demonstrate the operation of these\nvarious techniques.
Introduction of a loss-of-function point mutation from the SH3 region of the Caenorhabditis elegans sem-5 gene activates the transforming ability of c-abl in vivo and abolishes binding of proline-rich ligands in vitro. (1995)

We have introduced two loss-of-function point mutations from highly conserved regions of the src homology 3 (SH3) domains of the Caenorhabditis elegans sem-5 gene into the SH3 domain of the murine type IV c-abl tyrosine kinase proto-oncogene. One of the mutations, P131L, activated abl to transform fibroblasts while the other, G128R, did not. When combined with independent activating mutations in the c-abl kinase domain or NH2-terminus, the G128R mutation blocked transformation by the double mutant, suggesting that the G128R mutant was unable to transform cells for trivial reasons. The c-Abl G128R mutant, like wild type c-Abl protein, was localized to the nucleus and actin cytoskeleton and had normal tyrosine kinase activity in vitro, while the transforming c-Abl P131L protein was localized exclusively to the cytoplasm and exhibited decreased in vitro kinase activity. By real-time biospecific interaction analysis, the wild type Abl SH3 domain bound to two proteins containing proline-rich motifs with dissociation constants of 0.2 and 17 microM; the G128R mutant bound with 50-fold lower affinity, and no binding was detected by the P131L mutant. Both mutations completely abolished binding of the Abl SH3 domain to proline-rich target proteins in a filter-binding assay. These results suggest that the transforming activity of Abl is regulated in vivo by an inhibitor protein which associates with the SH3 domain via a proline-rich sequence.

Automatic 3D Car Model Alignment for Mixed Image-Based Rendering (2016)

Image-Based Rendering (IBR) allows good-quality free-viewpoint navigation in urban scenes, but suffers from artifacts on poorly reconstructed objects, e.g., reflective surfaces such as cars. To alleviate this problem, we propose a method that automatically identifies stock 3D models, aligns them in the 3D scene and performs morphing to better capture image contours. We do this by first adapting learning-based methods to detect and identify an object class/pose in images. We then propose a method which exploits all available information, namely partial and inaccurate 3D reconstruction, multi-view calibration, image contours and the 3D model to achieve accurate object alignment suitable for subsequent morphing. These steps provide models which are well-aligned in 3D and to contours in all the images of the multi-view dataset, allowing us to use the resulting model in our mixed IBR algorithm. Our results show significant improvement in image quality for free-viewpoint IBR, especially when moving far from the captured viewpoints.
Functional Materials for Bone Regeneration from Beta‐Tricalcium Phosphate (2004)

Abstract Biodegradable ceramics of β‐tricalcium phosphate (β‐TCP, Ca 3 (PO 4 ) 2 ) are widely used as bone regeneration materials. The goal is a complete regeneration of the bony defect ( restitutio ad integrum = full recovery). Different bioceramics made of β‐TCP show fundamental differences in terms of phase purity, primary particle size, stability, porosity, solubility and therefore biodegradation of the material. Cerasorb® is a bioceramic consisting of phase pure β‐TCP. The primary particle size in connection with a stable sinter structure forms a porous biomaterial which is optimised in the functional surface, porosity and resorption/degradation behaviour. Different forms of Cerasorb® are available: granular materials with high and low porosity optimised for specific indications as well as block forms shapeable by the surgeon for various bony defects.

The Application of Room Temperature Molten Salt with Low Viscosity to the Electrolyte for Dye-Sensitized Solar Cell (2001)

Abstract The effect of the viscosity of room temperature molten salt (RTMS) electrolyte has been investigated on the performance of dye-sensitized solar cell (DSSC). Both the short circuit photocurrent and conversion efficiency are increased with decreasing the viscosity of RTMS as in the case of conventional electrolytes. The conversion efficiency of 2.1% observed for the cell of EMIm-F·2.3HF is the highest value reported for all the DSSC consisted of RTMS.
Metabonomic characterization of early atherosclerosis in hamsters with induced cholesterol (2009)

Atherosclerosis is a complicated and multifactorial disease, induced not only by genotype, but also, even more importantly, by environmental factors. Study on the metabolic perturbation of endogenous compounds may offer deeper insight into development of atherosclerosis. Gas chromatography/mass spectrometry (GC/MS)-based metabonomics was used to profile a metabolic fingerprint of serum obtained from hamsters with induced cholesterol. The deconvoluted GC/MS data were processed by multivariate statistical analysis tools, such as principal component analysis (PCA) and partial least squares projection to latent structure and discriminant analysis (PLS-DA). For the first time we showed a time-dependent development of the model animal from normal to hypercholesterolaemia, and further to early atherosclerosis. Twenty-one compounds were identified as markers involved in the development to atherosclerosis. Identification of the compounds suggests that amino acid metabolism and fatty acid oxidation are significantly perturbed following cholesterol overloading. The data provide novel information to approach the pathophysiological processes of the hypercholesterolaemia and atherosclerosis disease continuum.
Score and Information for Recursive Exponential Models with Incomplete Data (2013)

Recursive graphical models usually underlie the statistical modelling concerning probabilistic expert systems based on Bayesian networks. This paper defines a version of these models, denoted as recursive exponential models, which have evolved by the desire to impose sophisticated domain knowledge onto local fragments of a model. Besides the structural knowledge, as specified by a given model, the statistical modelling may also include expert opinion about the values of parameters in the model. It is shown how to translate imprecise expert knowledge into approximately conjugate prior distributions. Based on possibly incomplete data, the score and the observed information are derived for these models. This accounts for both the traditional score and observed information, derived as derivatives of the log-likelihood, and the posterior score and observed information, derived as derivatives of the log-posterior distribution. Throughout the paper the specialization into recursive graphical models is accounted for by a simple example.

El sistema económico internacional en 2016 (2017)

A los 75 años de la creación del FMI y del Banco Mundial, el sistema económico internacional multilateral creado en Bretton Woods en 1944 está en crisis y la economía mundial está en una fase de crecimiento lento por el proteccionismo que ha hecho caer en decadencia la OMC. En 2019 hemos celebrado el trigésimo aniversario de la caída del Muro de Berlín sin que se vea el final de la historia que se predijo entonces sino que el sistema internacional, Europa (con las incertidumbres del brexit) y muchos países están sumidos en situaciones de malestar social, populismos y retraimiento inversor diez años después de la gran crisis de 2008. Todo ello genera pesimismo. España crece más que otros países europeos, pero el independentismo catalán, el proceso electoral semipermanente y la falta de presupuestos retienen las perspectivas.
Redox shuttle additives for overcharge protection in lithium batteries (1999)

Seven new redox shuttle additives with shuttle current onset potentials above 4.2 V vs Li/Li+ are reported, along with diffusion coefficients for the neutral additives. The dependence of the limiting shuttle current on the respective diffusion coefficients of the oxidized and reduced forms of an additive is clarified. Overcharge protection in liquid electrolyte Li/LiMn{sub 2}O{sub 4} cells is demonstrated.

Dynamic Changes in Apoptotic and Necrotic Cell Death Correlate with Severity of Ischemia–Reperfusion Injury in Lung Transplantation (2000)

Ischemia-reperfusion (IR) injury is a major cause of organ dysfunction following lung transplantation. We have recently described increased apoptosis in transplanted human lungs after graft reperfusion. However, a direct correlation between ischemic time, cell death, and posttransplant lung function has not yet been demonstrated. We hypothesized that an increased ischemic period would lead to an increase in cell death, and that the degree and type of cell death would correlate with lung function. To investigate this, we preserved rat lungs at 4 degrees C for 20 min and 6, 12, 18, and 24 h, and then transplanted the lungs and reperfused them for 2 h. Cell viability was determined with a triple staining technique combining trypan blue, terminal deoxynucleotidyl transferase-uridine nucleotide end-labeling, and propidium iodide nuclear staining. Percentages of apoptotic and necrotic cells were calculated from total cell numbers. Following 20 min and 6 and 12 h of cold preservation, less than 2% of graft cells were dead, whereas after 18 and 24 h of cold preservation, 11% and 27% of cells were dead (p < 0.05), the majority of which were necrotic. After transplantation and reperfusion, the mode of cell death changed significantly. In the 6- and 12-h groups, approximately 30% of cells were apoptotic and < 2% were necrotic, whereas in the 18- and 24-h groups, 21% and 29% of cells, respectively, were necrotic and less than 1% were apoptotic. Lung function (Pa(O(2))) decreased significantly (p < 0.05) with increasing preservation time. The percentage of necrotic cells was inversely correlated with posttransplant graft function (p < 0.0001). The study demonstrates a significant association among cold preservation time, extent and mode of cell death, and posttransplant lung function, and suggests new potential strategies to prevent and treat IR injury.
Substance P Promotes the Proliferation, but Inhibits Differentiation and Mineralization of Osteoblasts from Rats with Spinal Cord Injury via RANKL/OPG System (2016)

Spinal cord injury (SCI) causes a significant amount of bone loss, which results in osteoporosis (OP). The neuropeptide substance P (SP) and SP receptors may play important roles in the pathogenesis of OP after SCI. To identify the roles of SP in the bone marrow mesenchymal stem cell derived osteoblasts (BMSC-OB) in SCI rats, we investigated the expression of neurokinin-1 receptors (NK1R) in BMSC-OB and the effects of SP on bone formation by development of BMSC-OB cultures. Sixty young male Sprague-Dawley rats were randomized into two groups: SHAM and SCI. The expression of NK1R protein in BMSC-OB was observed using immunohistochemistry and Western blot analysis. The dose- and time-dependent effects of SP on the proliferation, differentiation and mineralization of BMSC-OB and the expression of osteoblastic markers by in vitro experiments. The expression of NK1R in BMSC-OB was observed on plasma membranes and in cytoplasm. One week after osteogenic differentiation, the expression of NK1R was significantly increased after SCI at mRNA and protein levels. However, this difference was gradually attenuated at 2 or 3 weeks later. SP have the function to enhance cell proliferation, inhibite cell differentiation and mineralization at a proper concentration and incubation time, and this effect would be inhibited by adding SP or NK1R antagonist. The expression of RANKL/OPG was significantly increased in tibiae after SCI. Similarly, the RANKL/OPG expression in SCI rats was significantly increased when treating with 10-8 M SP. SP plays a very important role in the pathogenesis of OP after SCI. The direct effect of SP may lead to increased bone resorption through the RANKL/OPG axis after SCI. In addition, high expression of SP also results in the suppression of osteogenesis in SCI rats. Then, the balance between bone resorption and bone formation was broken and finally osteoporosis occurred.
Coupled‐fed loop antenna with branch radiators for internal LTE/WWAN laptop computer antenna (2010)

Abstract A new antenna structure of internal long‐term evolution/wireless wide area network (698–960/1710–2690 MHz) laptop computer antenna formed by a coupled‐fed loop antenna connected with two branch radiators is presented. The two branch radiators consist of one longer strip and one shorter strip, both being efficient radiators and contributing multiresonant modes to greatly enhance the bandwidth of the antenna. The antenna's lower band is formed by a dual‐resonant mode mainly contributed by the longer branch strip, while the upper band is formed by three resonant modes contributed respectively by one higher‐order resonant mode of the longer branch strip, one resonant mode of the coupled‐fed loop antenna alone, and one resonant mode of the shorter branch strip. The antenna's lower and upper bands can therefore cover the desired 698–960 and 1710–2690 MHz bands, respectively. The proposed antenna is suitable to be mounted at the top shielding metal wall of the display ground of the laptop computer and occupies a small volume of 4 × 10 × 75 mm 3 above the top shielding metal wall, which makes it promising to be embedded inside the casing of the laptop computer as an internal antenna. Details of the proposed antenna are studied in the paper. © 2010 Wiley Periodicals, Inc. Microwave Opt Technol Lett 52:2662–2667, 2010; View this article online at wileyonlinelibrary.com.
