Grafting of acrylic acid onto flax fibers using Mn(IV)‐citric acid redox system (2006)

Abstract When the flax fibers (machine tow) were treated with KMnO 4 solution, MnO 2 was deposited over‐all the fiber surface. The amount of MnO 2 deposited relied on the KMnO 4 concentration. Subjecting the flax‐containing MnO 2 to a solution consisting of monomer (acrylic acid, AA) and citric acid, CA (or any acid used in this work) resulted in formation of poly(AA)‐flax graft copolymer. Dependence of the polymer criteria, namely, the total percentage conversion (%TC) and the carboxyl content of the grafted flax fibers on various grafting parameters, viz., concentrations of the redox pair as well as AA, material‐to‐liquor ratio ( M / R ), duration and temperature of polymerization, kind of the acid and kind of the flax fibers pretreatment was studied systematically. The results indicated that the polymerizability of AA molecules, expressed as %TC (i.e., counting both grafting and homopolymerization) and thence the carboxyl content (i.e., evaluating the extent of AA grafting along the flax backbone) was optimized with the following conditions: [AA], 100% (based on weight of flax fibers, owf); [CA], 0.4 meq/1 g flax; [MnO 2 ], 0.4 meq/1 g flax; polymerization temperature, 40°C; polymerization time, 30 min; and the M / R , 1 : 50. A tentative mechanism for grafting of flax fibers with AA using MnO 2 ‐acid redox system was elucidated. © 2006 Wiley Periodicals, Inc. J Appl Polym Sci 102: 3028–3036, 2006
Integrin β cytoplasmic domain interactions with phosphotyrosine-binding domains: A structural prototype for diversity in integrin signaling (2003)

The cytoplasmic domains (tails) of heterodimeric integrin adhesion receptors mediate integrins' biological functions by binding to cytoplasmic proteins. Most integrin beta tails contain one or two NPXYF motifs that can form beta turns. These motifs are part of a canonical recognition sequence for phosphotyrosine-binding (PTB) domains, protein modules that are present in a wide variety of signaling and cytoskeletal proteins. Indeed, talin and ICAP1-alpha bind to integrin beta tails by means of a PTB domain-NPXY ligand interaction. To assess the generality of this interaction we examined the binding of a series of recombinant PTB domains to a panel of short integrin beta tails. In addition to the known integrin-binding proteins, we found that Numb (a negative regulator of Notch signaling) and Dok-1 (a signaling adaptor involved in cell migration) and their isolated PTB domain bound to integrin tails. Furthermore, Dok-1 physically associated with integrin alpha IIb beta 3. Mutations of the integrin beta tails confirmed that these interactions are canonical PTB domain-ligand interactions. First, the interactions were blocked by mutation of an NPXY motif in the integrin tail. Second, integrin class-specific interactions were observed with the PTB domains of Dab, EPS8, and tensin. We used this specificity, and a molecular model of an integrin beta tail-PTB domain interaction to predict critical interacting residues. The importance of these residues was confirmed by generation of gain- and loss-of-function mutations in beta 7 and beta 3 tails. These data establish that short integrin beta tails interact with a large number of PTB domain-containing proteins through a structurally conserved mechanism.
Adsorption of 2,4-dichlorophenoxyacetic acid in an aqueous medium on nanoscale MIL-53(Al) type materials (2019)

A series of flexible metal-organic frameworks (MOFs) belonging to the MIL-53 family, such as MIL-53(Al), its amino-functionalized analog NH2-MIL-53(Al), and MIL-53(Al) type materials with Al3+ ions and mixed benzene-1,4-dicarboxylate and 2-aminobenzene-1,4-dicarboxylate linkers (MixLR) in various proportions were prepared in a nanocrystalline form using MW-activation under atmospheric pressure according to the original solvothermal procedure. The MIL-53(Al) and NH2-MIL-53(Al) samples feature nanocrystals with sizes of 200-300 nm, while MixLR matrices synthesized in this manner are composed of small nanoparticles with sizes of about 20-30 nm. MIL-53(Al) type materials (MIL-53(Al), NH2-MIL-53(Al) and MixLR) were probed in the adsorption of a typical herbicide 2,4-dichlorophenoxyacetic acid (2,4-D) in an aqueous medium. This study revealed a strong impact of the flexibility and porosity of the synthesized MIL-53(Al) type matrices on their physicochemical characteristics. MIL-53(Al) type materials show much higher 2,4-D adsorption rates than an activated carbon matrix (CSAC). The structural characteristics of the studied MIL-53(Al) type materials were established with a high resolution X-ray powder diffractometer equipped with a synchrotron radiation source. The obtained results can be used for the development of advanced adsorbents based on MIL-53(Al) type materials for water remediation.
A Scalable Reference Standard of Visual Similarity for a Content-Based Image Retrieval System (2011)

In order to develop content based image retrieval (CBIR) systems, a robust reference standard of similarity between pairs of images is required, but challenging to create given the large number of pair-wise comparisons. We demonstrated a novel method of creating one for liver tumors seen in 19 portal venous CT scans by computing image similarity from subjective ratings of attributes on single images. We gathered ratings with 6- and 9-point scales for liver lesions displayed individually (P1: ratings for 6 visual attributes) and in all 171 pair-wise combinations (P2: ratings for dissimilarity in the 6 attributes and overall dissimilarity) from 3 radiologists. We averaged readers' ratings and fit the absolute attribute rating differences in P1 to ratings in P2. The R-squared value between pair-wise attribute dissimilarities and overall pair-wise dissimilarity was 0.65, and between a linear combination of the absolute differences of ratings for each attribute and overall pair-wise dissimilarity was 0.46. For overall dissimilarity, pairs of readers showed agreement to within 2 points in 64-84% of all ratings. Hence, this scalable method is feasible for creating a reference standard for CBIR.

Efficient one-vs-one kernel ridge regression for speech recognition (2016)

Recent evidences suggest that the performance of kernel methods may match that of deep neural networks (DNNs), which have been the state-of-the-art approach for speech recognition. In this work, we present an improvement of the kernel ridge regression studied in Huang et al., ICASSP 2014, and show that our proposal is computationally advantageous. Our approach performs classifications by using the one-vs-one scheme, which, under certain assumptions, reduces the costs of the one-vs-rest scheme by asymptotically a factor of c2 in training time and c in memory consumption. Here, c is the number of classes and it is typically on the order of hundreds and thousands for speech recognition. We demonstrate empirical results on the benchmark corpus TIMIT. In particular, the classification accuracy is one to two percentages higher (in the absolute term) than the best of the kernel methods and of the DNNs reported by Huang et al, and the speech recognition accuracy is highly comparable.
Dynamic light scattering from ternary polymer blends: critical behavior and bicontinuous microemulsions (2000)

We have used dynamic light scattering to study the dynamics of ternary polymer blends consisting of poly(dimethylsiloxane) (PDMS) and poly(ethylethylene) (PEE) homopolymers and a PDMS-PEE diblock copolymer nearly symmetric in composition. The intensity autocorrelation functions for the binary blend are single-exponential, and the associated correlation length ξ scales with reduced temperature ϵ in accordance with the Ising universality class (i.e., ξ ∼ ϵ−ν, with ν = 0.63). An addition of copolymer depresses the critical temperature, but also increases the magnitude of ν. For compositions within the microemulsion channel, ξ exhibits a distinct maximum with decreasing temperature, near the Lifshitz line obtained from the static structure factor. For a particular composition, there is a “re-entrant” microemulsion, as the system passes into and then out of the phase-separated region upon cooling.
LHRH-Targeted Nanoparticles for Cancer Therapeutics (2010)

Synthesis and evaluation of a novel cancer cell's receptor-targeted internally quaternized and surface neutral poly(amidoamine) (PAMAM) generation four dendrimer as well as PAMAM-paclitaxel conjugate are described. The advantages of developed nanocarriers include but are not limited to (1) internal cationic charges for the complexation with small interfering RNA or antisense oligonucleotides and their protection from the degradation in systemic circulation; (2) neutral-modified surface for low cytotoxicity of empty unloaded dendrimers; (3) efficient internalization by cancer cells; and (4) preferential accumulation in the tumor and the prevention of adverse side effects of chemotherapy.

MO-F-213AB-04: Biological Effect of Dose Shadowing by Fiducial Markers in Spot Scanning Proton Therapy with a Limited Number of Fields (2012)

Although dose shadowing by the gold marker is locally non-negligible, the size of the affected domain is tiny. It was found that with a minimum number of fields, the TCP nearly recovers to the value without the gold marker.
Fabrication and Efficiency Improvement of Soluble Blue Phosphorescent Organic Light‐Emitting Diodes Using a Multilayer Structure Based on an Alcohol‐Soluble Blue Phosphorescent Emitting Layer (2010)

Highly efficient soluble blue phosphorescent organic light emitting diodes have been developed using a multilayer device structure based on alcohol soluble blue phosphorescent emitting layer. A device structure with double emitting layer and an exciton blocking layer could be fabricated due to orthogonal film formation and a high quantum efficiency of 14.1% and a current efficiency of 30.4 cd/A were achieved in the soluble blue phosphorescent organic light emitting diodes.
Physisorption of Affinity Ligands Facilitates Extracellular Vesicle Detection with Low Non-Specific Binding to Plasmonic Gold Substrates (2022)

Plasmonic biosensors are increasingly being used for the analysis of extracellular vesicles (EVs) originating from disease areas. However, the high non-specific binding of EVs to a gold-sensing surface has been a critical problem and hindered the true translational potential. Here, we report that direct antibody immobilization on the plasmonic gold surface via physisorption shows excellent capture of cancer-derived EVs with ultralow non-specific binding even at very high concentrations. Contrary to commonly used methods that involve thiol-based linker attachment and an EDC/sulfo-NHS reaction, we show a higher specific capture rate and >50-fold lower non-specific on citrate-capped plain and nanopatterned gold surfaces. The method provides a simple, fast, and reproducible means to functionalize plasmonic gold surfaces with antibodies for robust EV biosensing.
Mechanical and electrical characterisation in age hardened Waspaloy microstructures (2009)

Nickel-base superalloys such as Waspaloy possess excellent mechanical properties at elevated temperatures. This is possible through precipitation hardening, whereby submicron precipitate phases (γ′) are formed in the nickel-rich matrix phase (γ) under controlled aging heat treatments. The current work is focused on studying microstructural evolution in systematically aged Waspaloy specimens through mechanical and electrical characterisation conducted via Vickers microhardness and four probe resistivity measurements respectively. Four bars of industrial grade Waspaloy were solution treated at 1145°C and aged at temperatures of 600, 725, 800 and 875°C for times ranging from 2 min to 763·5 h. For the specimens aged at 600 and 725°C, the maximum in hardness was not reached. However, maxima in hardness and conductivity occur at similar aging times for the samples aged at 800 and 875°C. The present studies indicate that conductivity measurements show potential for ascertaining the hardness of the alloy relative to the over-aged state.
Detailed Placement for IR Drop Mitigation by Power Staple Insertion in Sub-10nm VLSI (2019)

Power Delivery Network (PDN) is one of the most challenging topics in modern VLSI design. Due to aggressive technology node scaling, resistance of back-end-of-line (BEOL) layers increases dramatically in sub-10nm VLSI, causing high supply voltage (IR) drop. To solve this problem, pre-placed or post-placed power staples are inserted in pin-access layers to connect adjacent power rails and reduce PDN resistance, at the cost of reduced routing flexibility, or reduced power staple insertion opportunity. In this work, we propose dynamic programming-based single-row and double-row detailed placement optimizations to maximize the power staple insertion in a post-placement flow. We further propose metaheuristics to improve the quality of result. Compared to the traditional post-placement flow, we achieve up to 13.2% (10mV ) reduction in IR drop, with almost no WNS degradation.
Induction of interleukin-1β, tumour necrosis factor-α and apoptosis in mouse organs by amphotericin B is neutralized by conjugation with arabinogalactan (2005)

AMB-related toxicity is associated with induction of IL-1beta, TNF-alpha and apoptosis in organs. These effects were not observed with AMB-AG conjugate, suggesting its potential as a safer formulation for therapy.
Decentralized beamforming for weighted sum rate maximization with rate constraints (2013)

A novel decentralized beamformer design for weighted sum rate maximization with user specific rate constraints is proposed for interfering multiple-input multiple-output (MIMO) broadcast channel (BC). In order to reduce the inherent complexity of the rate maximizing beamformer design, alternating receive and transmit beamformer generation together with successive convex approximation are applied. The rate maximization problem is reduced to mean-squared error (MSE) minimization with spatial data stream specific weighting factors that imply the inter-stream interference costs, where the weights depend additionally on the violation of the rate constraints. The iterative process is based on the Lagrangian relaxation of the rate constraints, and, thus, each intermediate beamformer solution is not required to be strictly feasible in terms of the rate constraints but rather steers the algorithm towards a solution with feasible rate constraints. Exchange of the weighting factors among the adjacent cells provides decentralized problem formulation for TDD based systems with a very low over-the-air signaling overhead.
Optimizing polynomial solvers for minimal geometry problems (2011)

In recent years polynomial solvers based on algebraic geometry techniques, and specifically the action matrix method, have become popular for solving minimal problems in computer vision. In this paper we develop a new method for reducing the computational time and improving numerical stability of algorithms using this method. To achieve this, we propose and prove a set of algebraic conditions which allow us to reduce the size of the elimination template (polynomial coefficient matrix), which leads to faster LU or QR decomposition. Our technique is generic and has potential to improve performance of many solvers that use the action matrix method. We demonstrate the approach on specific examples, including an image stitching algorithm where computation time is halved and single precision arithmetic can be used.

Fusing Multi-Stream Deep Networks for Video Classification (2015)

This paper studies deep network architectures to address the problem of video classification. A multi-stream framework is proposed to fully utilize the rich multimodal information in videos. Specifically, we first train three Convolutional Neural Networks to model spatial, short-term motion and audio clues respectively. Long Short Term Memory networks are then adopted to explore long-term temporal dynamics. With the outputs of the individual streams, we propose a simple and effective fusion method to generate the final predictions, where the optimal fusion weights are learned adaptively for each class, and the learning process is regularized by automatically estimated class relationships. Our contributions are two-fold. First, the proposed multi-stream framework is able to exploit multimodal features that are more comprehensive than those previously attempted. Second, we demonstrate that the adaptive fusion method using the class relationship as a regularizer outperforms traditional alternatives that estimate the weights in a "free" fashion. Our framework produces significantly better results than the state of the arts on two popular benchmarks, 92.2\% on UCF-101 (without using audio) and 84.9\% on Columbia Consumer Videos.
Large volume, high‐performance applications of fibers in civil engineering (2001)

Abstract This article presents an overview of fiber applications in cementitious composites. The socio‐economic considerations surrounding materials development in civil engineering in general, and fiber reinforced cementitious materials in particular, are described. Current FRC appliations are summarized, and the where, how, and why fibers are used in these applications, are documented. An attempt is made to extract common denominators among the widely varied applications. The R&amp;D and industrial trends of applying fibers in enhancing structural performance are depicted. An actual case study involving a tunnel lining constructed in Japan is given to illustrate how a newly proposed structural design guideline takes into account the load carrying contribution of fibers. Composite properties related to structural performance are described for a number of FRCs targeted for use in load carrying structural members. Structural applications of FRCs are currently under rapid development. In coming years, it is envisioned that the ultra‐high performance FRC, with ductility matching that of metals, will be commercially exploited in various applications. Highlights of such a material are presented in this article. Finally, conclusions on market trends are drawn, and favorable fiber characteristics for structural applications are provided. © 2002 Wiley Periodicals, Inc. J Appl Polym Sci 83: 660–686, 2002
Implicit representation and scene reconstruction from probability density functions (2003)

A technique is presented for representing linear features as probability density functions in two or three dimensions. Three chief advantages of this approach are (1) a unified representation and algebra for manipulating points, lines, and planes, (2) seamless incorporation of uncertainty information, and (3) a very simple recursive solution for maximum likelihood shape estimation. Applications to uncalibrated affine scene reconstruction are presented, with results on images of an outdoor environment.
<title>Machine vision platform requirements for successful implementation and support in the semiconductor assembly manufacturing environment</title> (1991)

In todays Semiconductor Manufacturing Industry it is becoming more difficult to utilize the human operator as the visual process control vehicle so as to cost-effectively achieve statistical process defect goals. Machine vision continues to make inroads cost-effectively improving manufacturing visual inspection requirements driving and sustaining desired process control capabilities. This paper will attempt to survey the attributes of automatic visual process monitoring within the Motorola Semiconductor Assembly Manufacturing environment. Such factors as defect control objectives inspection requirements vision engine platform application engineering and long-term application maintenance all of which contribute to the costeffectiveness of the automatic visual inspection task.
Rare Genes of Major Effect in Neuropsychiatric Diseases (2007)

In comparison to the early and rapid successes with single-gene, Mendelian disorders, research into complex genetic disorders has seemed interminably slow, contradictory, and intractable (1). Neuropsychiatric disorders have demonstrated this recalcitrant behavior well and, indeed, to researchers in the field it sometimes feels like they are even more “complex” than other “complex genetic disorders” such as diabetes, cancers, asthma, coronary artery disease, and autoimmune conditions. The aspects of disorders, which make them genetically “complex” can be thought of in two ways. First, the underlying genetic risk factors are numerous and often without a direct genotype-to-phenotype correlation. Second, the complex disorder phenotype may be broader and more diffuse-certainly at a clinical level where it is often a clinical diagnostic end point (e.g., obesity, blood pressure, stroke, behavior, and communicated cognitions) rather than a unifying pathophysiology (e.g., cystic fibrosis lung pathology).
Highly conductive PdCoO2 ultrathin films for transparent electrodes (2018)

We report on the successful synthesis of highly conductive PdCoO2 ultrathin films on Al2O3 (0001) by pulsed laser deposition. The thin films grow along the c-axis of the layered delafossite structure of PdCoO2, corresponding to the alternating stacking of conductive Pd layers and CoO2 octahedra. The thickness-dependent transport measurement reveals that each Pd layer has a homogeneous sheet conductance as high as 5.5 mS in the samples thicker than the critical thickness of 2.1 nm. Even at the critical thickness, high conductivity exceeding 104 S cm−1 is achieved. Optical transmittance spectra exhibit high optical transparency of PdCoO2 thin films particularly in the near-infrared region. The concomitant high values of electrical conductivity and optical transmittance make PdCoO2 ultrathin films promising transparent electrodes for triangular-lattice-based materials.
