Strain Evolution in High Temperature AlN Buffer Layers for HVPE-GaN Growth (2002)

High temperature AlN buffer layers are deposited on a-plane sapphire by reactive magnetron sputtering. The effect of the buffer thickness on the AlN structural properties and surface morphology are studied in correlation with the subsequent hydride vapour phase epitaxy of GaN. A minimum degree of mosaicity and screw dislocation density is determined for a 50 nm thick AlN buffer. With increasing the AlN thickness, a strain relaxation occurs as a result of misfit dislocation generation and higher degree of mosaicity. A blue shift of the E1(TO) frequency evaluated by means of infrared reflection spectroscopy is linearly correlated with an increase in biaxial compressive stress in the films through the IR stress factor kb = 2.57 ± 0.26 cm—1 GPa—1.

Using genetic variation to optimize cancer chemotherapy. (2003)

The high level of interpatient variation in response to chemotherapy and the lack of objective tools to select chemotherapy regimens for a given tumor type have created a clinical problem. A possible solution may be pharmacogenetics: the study of inherited DNA polymorphisms that influence drug disposition and effects in order to individualize drug treatment. Because unpredictable efficacy and high levels of systemic toxicity are common in cancer chemotherapy, pharmacogenetics is particularly appealing to oncologists. Polymorphisms in drug metabolism, drug transport, drug target, and DNA repair genes have been implicated interpatient variability in response to many chemotherapy agents. This review will discuss recent clinically relevant examples of cancer pharmacogenetics and how genetic differences are helping to shape the future of individualized cancer chemotherapy.
Demosaicking of Hexagonally-Structured Bayer Color Filter Array (2014)

This paper describes a demosaicking method for hexagonally-structured color filter array. Demosaicking is essential to acquire color images using color filter array (CFA) in single sensor imaging. Thus, CFA patterns have been discussed in order to improve image quality in single sensor imaging after the Bayer pattern are introduced. Advancements in imaging sensor technology recently introduce a hexagonal CFA pattern. The hexagonal CFA can be considered to be a 45-degree rotational version of the Bayer pattern, thus demosaicking can be implemented by an existing method with backward and forward 45-degree rotations. However, this approach requires heavy computing power and memory in image sensing devices because of the image rotations. To overcome this problem, we proposes a demosaicking method for a hexagonal Bayer CFA without rotations. In addition, we introduce a weighting parameter in our demosaicking method to improve image quality and to unifying exiting method with our method. Experimental results indicate that the proposed method is superior to conventional methods in terms of PSNR. In addition, some optimized values for the weighting parameter are provided experimentally.

A novel 2-dimensional artificial pinning center (2008)

To increase critical current density (JC) in magnetic fields (B) parallel to the c-axis, 2-dimensional artificial pinning centers (APCs) are introduced into YBa2Cu3O7-δ (Y123) films. Multilayer films alternately stacked a-axis oriented Y123 and Pr123 (Y123/Pr123 multilayer films) have been grown on SrLaGaO4 substrates by pulsed laser deposition. Magnetic field angular dependences of the JC showed peaks not only in B // a-axis but also in B // c-axis of the Y123/Pr123 multilayer films. This result indicates that the Y123/Pr123 multilayer films have c-axis-correlated pinning centers. Consequently, it is suggested that the Pr123 layers act as 2-dimentional APCs.
Identification of Leachables from Trametes versicolor in Biodegradation Experiments (2018)

The transport of fungal-derived compounds from Trametes versicolor to the environment was investigated. Fatty acids and sphingoids were identified at the outlet of a bioreactor containing an acidic nutrient solution and immobilized fungal mycelia. The analyses were conducted using UHPLC-Q-TOF-MS (/MS). Eleven fatty acids, including C20:0, C18:1-OH and C20:0-OH that have not been previously described for this species, were detected. The identities of myristic acid (C14:0), palmitic acid (C16:0) and stearic acid (C18:0) were confirmed using reference standards. Six sphingoids, including Sph (t18:0), Sph (t18:1), Sph (d18:0), Sph (d18:1), Sph (d16:0) and Sph (d16:1), were tentatively identified, and the identities of Sph (d18:0) and Sph (d18:1) were confirmed by reference standards. The findings show that an array of compounds, with concentrations at the μgL-1 level, was easily transported from the fungal mycelia. This is of concern when the investigated species is used in biodegradation experiments of xenobiotics and conclusions are to be drawn on the quality of the treated water. The study thus shows that the chemical composition of water treated with Trametes versicolor is also influenced by the immobilized fungus itself. The lipids that were detected, including fatty acids and sphingoids do not present any threat to the environment since they are not toxic. At μgL-1 concentration levels, they are soluble in water.
Stabilization of 14xx-nm high power semiconductor laser by single fiber Bragg grating configuration (2016)

Output power stabilization of 14xx-nm high power semiconductor laser is achieved by using single fiber Bragg grating with relatively low reflectivity and large external cavity length. Well suppressed stimulated Brillouin scattering is confirmed for Raman amplifier applications.
Neuropeptide Y stimulation of myosin light chain phosphorylation in cultured aortic smooth muscle cells. (1990)

Neuropeptide Y (NPY) is released from an extensive network of postganglionic sympathetic perivascular neurons. NPY has been shown to affect vascular tone postsynaptically by 1) directly stimulating contraction; 2) inhibiting vasorelaxation; and 3) potentiating contraction elicited by exogenous vasoconstrictors. The molecular mechanisms mediating these effects of NPY are undefined. Therefore, we examined the possibility that NPY could stimulate smooth muscle contraction through myosin light chain phosphorylation in cultured porcine aortic smooth muscle cells. NPY (100 nM) caused a rapid, transient increase in myosin light chain (MLC) phosphorylation, an important regulatory event in the initiation of smooth muscle contraction. NPY-stimulated MLC phosphorylation was prevented by preincubation of cells with pertussis toxin and was independent of extracellular Ca2+. In parallel studies, NPY alone had no detectable effect on cellular cAMP or cGMP content; however, NPY potently inhibited forskolin-stimulated cAMP accumulation (IC50 = 0.03 nM) through a pertussis toxin-sensitive pathway. NPY had no detectable effect on basal phosphoinositide hydrolysis or protein kinase C activation but enhanced angiotensin II-stimulated production of inositol phosphates and activation of protein kinase C. These results indicate that NPY-stimulated MLC phosphorylation can occur in the absence of detectable changes in cAMP content, cGMP content, inositol phosphate production, or protein kinase C activation; however, the interactions between NPY and other vasoactive agents may be mediated by the indirect effects of NPY on adenylate cyclase activity and phosphoinositide hydrolysis.

Clinical use of biomarkers of survival in pulmonary fibrosis (2010)

Serum biomarkers, and markers measured by medical imaging as HRCT, pertechnegas, DTPA en FDG-PET are not ready for clinical use to predict mortality in different forms of ILD. A baseline FVC, a change of FVC of more than 10%, and change in 6MWD are clinically helpful predictors of survival.
Down-regulation of Caveolin-1, an Inhibitor of Transforming Growth Factor- Signaling, in Acute Allergen-induced (2008)

Asthma can progress to subepithelial airway fibrosis, mediated in large part by transforming growth factor- (TGF-). The scaffolding protein caveolin-1 (cav1) can inhibit the activity of TGF-, perhaps by forming membrane invaginations that enfold TGF- receptors. The study goals were 1) to evaluate how allergen challenge affects lung expression of cav1 and the density of caveolae in vivo 2) to determine whether reduced cav1 expression is mediated by interleukin (IL)-4 and 3) to measure the effects of decreased expression of cav1 on TGF- signaling. C57BL/6J, IL-4-deficient mice, and cav1-deficient mice, sensitized by intraperitoneal injections of phosphate-buffered saline or ovalbumin (OVA) at days 0 and 12, received intranasal phosphate-buffered saline or OVA challenges at days 24, 26, and 28. Additionally, another group of C57BL/6J mice received IL-4 by intratracheal instillation for 7 days. We confirmed that the OVA-allergen challenge increased eosinophilia and T-helper type 2-related cytokine levels (IL-4, IL-5, and IL-13) in bronchoalveolar lavage. Allergen challenge reduced lung cav1 mRNA abundance by 40%, cav1 protein by 30%, and the number of lung fibroblast caveolae by 50%. Administration of IL-4 in vivo also substantially decreased cav1 expression. In contrast, the allergen challenge did not decrease cav1 expression in IL-4deficient mice. The reduced expression of cav1 was associated with activation of TGF- signaling that was further enhanced in OVA-sensitized and challenged cav1-deficient mice. This study demonstrates a previously unknown modulation of TGF- signaling by IL-4, via cav1, suggesting novel therapeutic targets for controlling the effects of TGF- and thereby ameliorating pathological airway remodeling.
Development of a coarse-grain model for the description of the metal oxide-polymer interface from a bottom-up approach (2019)

We present a coarse-grained model for using dissipative particle dynamics simulations to study the interaction between cis-1,4 polybutadiene polymer chains and a metal oxide (Cu2O) surface at the mesoscopic scale. We employ a bottom-up approach in order to link the structural properties with their underlying molecular properties over a wide range of time and length scales. The parameterization of the model was realized using a recently developed Bayesian scheme that is based on trajectory matching of an atomistic description of the system. The model is used to investigate the local structure of polymers in a confined slab geometry by means of density profiles, radius of gyration, orientation with respect to the surface, and their adsorption.
Reduction of Hexavalent Chromium in Water Using Iron-Aluminum Bimetallic Particles (2013)

Metal finishing wastewater containing chromium was conventionally treated by chemical precipitation and ion exchange techniques. Zero-valent metals such as iron, aluminum, zinc that possess high reduction potentials are frequently employed to remediate and process the contaminated groundwater. Iron-aluminum bimetallic metal (Fe-Al) is developed to improve the reduction capacity of Fe, Al is regarded as the electron supplier to prevent the precipitates formed on the surface of Fe. The aim of this research is to study the performance of Fe-Al on the reduction of hexavalent chromium ion (Cr 6+ ) in water under several operation parameters including initial pH value, dosage of Fe-Al to Cr 6+ ratio (Fe-Al/Cr +6 ), and Fe contents of Fe-Al particles. The results indicated that the sizes and specific surface area of Fe-Al particles increased with higher Fe content. The metal species on the surface of Fe-Al particles were identified by an x-ray diffraction spectrometer (XRD). Reduction of Cr 6+ with Fe-Al particles consumes the H + in water resulting in the increase of pH value with the reaction time. The study showed that the reduction potentials of Fe-Al on Cr 6+ are promoted under acidic state and with higher dosage of Fe-Al/Cr +6 .
Distributed multi-view video coding (2006)

There are mainly two key points which can affect the efficiency of multi-view video capture and transmission system largely: communication between cameras and computing complexity of encoder. In this paper, we propose a practical framework of distributed multi-view video coding, in which inter-camera communication is avoided and the large computing complexity is moved from encoder to decoder. In this scheme, multi-camera video sources are encoded separately and decoded dependently, and the traditional inter frame is replaced by Wyner-Ziv frame. To reach this goal, Wyner-Ziv theory on source coding with side information is employed as the basic coding principle. A Wyner-Ziv coding method based on wavelet transform and turbo codes is used as the core of the scheme. To further improve the coding performance, we also consider exploiting the large redundancy between adjacent views. A more flexible prediction method that can jointly use temporal and view correlations is proposed to generate the side information at the decoder. The experimental results show that the coding performance of proposed DMVC scheme is very promising compared to the traditional intra coding.

Can we learn a template-independent wrapper for news article extraction from a single training site? (2009)

Automatic news extraction from news pages is important in many Web applications such as news aggregation. However, the existing news extraction methods based on template-level wrapper induction have three serious limitations. First, the existing methods cannot correctly extract pages belonging to an unseen template. Second, it is costly to maintain up-to-date wrappers for a large amount of news websites, because any change of a template may invalidate the corresponding wrapper. Last, the existing methods can merely extract unformatted plain texts, and thus are not user friendly. In this paper, we tackle the problem of template-independent Web news extraction in a user-friendly way. We formalize Web news extraction as a machine learning problem and learn a template-independent wrapper using a very small number of labeled news pages from a single site. Novel features dedicated to news titles and bodies are developed. Correlations between news titles and news bodies are exploited. Our template-independent wrapper can extract news pages from different sites regardless of templates. Moreover, our approach can extract not only texts, but also images and animates within the news bodies and the extracted news articles are in the same visual style as in the original pages. In our experiments, a wrapper learned from 40 pages from a single news site achieved an accuracy of 98.1% on 3,973 news pages from 12 news sites.
Phase based SNR estimation in OFDM over the medium voltage network (2009)

Modern digital communications over the aggressive medium voltage network (MVN) channel are based on reliable signal to noise ratio (SNR) estimation. In this work, a novel phase based SNR estimation method for Orthogonal Frequency Division Multiplexing (OFDM) systems transmitting over the MVN is proposed. By exploiting the fact that under additive white Gaussian noise (AWGN) conditions the phase errors at the receiver are normally distributed when the real SNR is over 10dB, the method estimates the SNR by only making use of the signal's phase samples. The knowledge of the current channel's transfer function as well as the current transmission power is not necessary for the SNR estimation, which simplifies the calculations and increases the method's applicability in practical systems communicating within the MVN environment. Immunity against constant phase errors and phase jitter caused by noise, the MVN channel or/and realistic OFDM synchronization count to further beneficial properties of the proposed estimator.
Learning Nonlinear Dynamics and Chaos: A Universal Framework for Knowledge-Based System Identification and Prediction. (2020)

We present a universal framework for learning the behavior of dynamical systems from observations. We formulate the learning task as a constrained optimization problem which can be efficiently solved with the adjoint sensitivity method. Our scheme is flexible with regards to the choice of model, and existing knowledge can be readily incorporated for hybrid learning. We demonstrate the effectiveness of our scheme by learning a variety of systems including a stiff Van der Pol oscillator, a chaotic Lorenz system, and the Kuramoto-Sivashinsky equation. We also include examples of hybrid learning and learning from noisy observations.
Database Matching Under Noisy Synchronization Errors (2023)

The re-identification or de-anonymization of users from anonymized data through matching with publicly available correlated user data has raised privacy concerns, leading to the complementary measure of obfuscation in addition to anonymization. Recent research provides a fundamental understanding of the conditions under which privacy attacks, in the form of database matching, are successful in the presence of obfuscation. Motivated by synchronization errors stemming from the sampling of time-indexed databases, this paper presents a unified framework considering both obfuscation and synchronization errors and investigates the matching of databases under noisy entry repetitions. By investigating different structures for the repetition pattern, replica detection and seeded deletion detection algorithms are devised and sufficient and necessary conditions for successful matching are derived. Finally, the impacts of some variations of the underlying assumptions, such as the adversarial deletion model, seedless database matching, and zero-rate regime, on the results are discussed. Overall, our results provide insights into the privacy-preserving publication of anonymized and obfuscated time-indexed data as well as the closely related problem of the capacity of synchronization channels.
