In situ thermoset molecular composites (1994)

Abstract The polymerization of rigid rod polymer precursors in a reactive matrix precursor, which is later cured in the mold, constitutes the in situ process. A poly‐azomethine (PAM) was used as the rigid rod molecule. The resin used was an epoxy. We discuss the prediction of mechanical properties using micromechanics equations for chopped fiber composites. The chemistry used to synthesize the rigid rod polymer PAM in the epoxy precursor is reviewed. Approaches to better control the cure of these epoxy systems through cure kinetics and cure rheology studies completes the thermoset in situ molecular composite process. There was a 71% increase in tensile modulus in comparison to that of the neat epoxy resin. Molecular modeling simulations and continuum mechanics are used to help understand these findings. PAM/epoxy systems were used as a matrix material in the fabrication of unidirectional glass fiber/(PAM/epoxy) structural composites. © 1994 John Wiley &amp; Sons, Inc.
Evidence for Zc±(3900) in semi-inclusive decays of b-flavored hadrons (2018)

We present evidence for the exotic charged charmoniumlike state $Z_{c}^{±}(3900)$ decaying to $J/ψπ^±$ in semi-inclusive weak decays of $b$-flavored hadrons. The signal is correlated with a parent $J/ψπ^+ π^-$ system in the invariant-mass range 4.2–4.7 GeV that would include the exotic structure $Y(4260)$. The study is based on $10.4 fb^{−1}$ of $p\bar{p}$ collision data collected by the D0 experiment at the Fermilab Tevatron collider.
Modified gas-permeable silicone rubber membranes for covalent immobilisation of enzymes and their use in biosensor development (1999)

Novel enzyme membranes are introduced. Modified polymeric gas-permeable layers were developed enabling biological components which have available reactive groups (-NH2, -OH, -SH, -COOH) to couple covalently on to their surfaces. Therefore, gas-permeable two component room temperature vulcanizing (2K-RTV) silicone rubber was modified using additional cross-linking agents. Triethoxysilanes with functional groups on their side chains such as epoxy or amino groups were used. A special attribute of the resulting gas-permeable membranes is that their formation and modification occur simultaneously during one reaction step. IR spectroscopy was used to observe the changes in the polymeric structure due to the reaction with the additional cross-linking agents. Sensors equipped with these layers are suitable to measure dissolved gases such as O2, CO2 and NH3 consumed or produced by enzymes converting their substrates. Determination of glucose, a well investigated enzymatic detection process, was chosen to demonstrate the applicability of the enzyme immobilisation. Glucose oxidase was immobilised on the membranes and glucose was detected by amperometric measurement of oxygen consumption. It is expected that this immobilisation method will also be useful for miniaturised planar biosensors.
Galvanomagnetic and Thermoelectric Properties of R3Cu3Sb4 Compounds (2006)

Zintl phases recently received a great attention for their thermoelectric potential and interesting results were reported on Yb <sub xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">14</sub> MnSb <sub xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">11</sub> compounds [Brown, et al., 2006].

They were synthesized in an induction furnace, followed by consequent annealing treatments. The crystallographic structure was checked by X-ray diffraction analysis. Resistivity and thermopower measurements were performed over a large temperature range going from 2 to 550 K. The low temperature thermal conductivity dependence of these materials was also determined between 10 to 300 K. Finally, the thermoelectric potential of these polycrystalline samples is discussed
An analytical study of dilution jet mixing in a cylindrical duct (1993)

The mixing performance in a mixing section of a rich burn/quick mix/lean burn (RQL) combustor was calculated using a 3-D numerical model in a non-reacting environment. The numerically calculated results were compared with the measured data reported by Hatch, Sowa, Samuelsen, and Holdeman, 1992. The numerical 3-D temperature fields qualitatively agree with the experimental data. Also, the development of the mixing flow and temperature non-uniformity trends throughout the mixing section for the numerically calculated results quantitatively agree with the measured data. The numerical model predicts less mixing and enhances the temperature gradients as compared to the measured data for the cases reported by Hatch et al. (1992) which include circular and slot orifice shapes (with different slant angles and aspect ratios). The predicted and measured results generally agree in the selection of the slanted slot orifice configuration yielding the best overall mixing performance (based on temperature uniformity) of all the configurations analyzed.
Differential sensitivity of human myeloma cell lines and normal bone marrow colony forming cells to a recombinant diphtheria toxin‐interleukin 6 fusion protein (1993)

The cytotoxicity of a recombinant interleukin 6 (IL-6)-diphtheria toxin (DT) fusion protein towards human myeloma cell lines was investigated. DAB389-IL-6 inhibited protein synthesis and methylcellulose colony formation by U266 myeloma cells. In the clonogenic assay, the fusion protein approached the level of cytotoxicity achieved by native DT. The specificity of killing by DAB389-IL-6 was demonstrated by inhibition of cytotoxicity by a molar excess of free rhIL-6. The effect of DAB389-IL-6 on colony formation by six OCI-My cell lines was assessed. Similar to U266 cells, colony growth by the OCI-My 5 and -My 2 cell lines was inhibited in a simple dose dependent manner. However, a biphasic effect was observed for the IL-6 dependent OCI-My 4 cells; DAB389-IL-6 stimulated colony formation at low (< or = 10(-11) M) concentrations, yet was inhibitory at higher doses. Three other cell lines whose growth was not altered by IL-6 were relatively unaffected by DAB389-IL-6, despite their sensitivity to native DT. Flow cytometric analysis for IL-6 receptor expression using phycoerythrin-conjugated IL-6 demonstrated specific binding sites on both DAB389-IL-6 sensitive and certain insensitive cell lines, suggesting that other factors in addition to the expression of IL-6 receptors are involved in killing by the fusion toxin. Despite evidence for a role of IL-6 in myeloid cell development, normal bone marrow was insensitive to the IL-6 fusion toxin. In cultures containing both normal bone marrow and U266 cells DAB389-IL-6 effectively inhibited the growth of U266 myeloma colonies but had little effect on normal bone marrow erythroid, granulocyte and mixed erythroid/granulocyte colony growth. From these experiments we conclude that DAB389-IL-6 is specifically cytotoxic towards a subset of IL-6-responsive human myeloma cell lines and may be useful, in some cases, in the selective elimination of tumour cells from mixed populations of normal and malignant cells.
Ciencia y académicos de la Historia en la Ilustración española: la emergencia del autor colectivo / Historical Science and the Royal Academy during the Spanish Age of Enlightenment: The Rise of the Collective Author (2017)

The concept of “shadow author” enables different approaches, from perspectives which question the presence or absence of an individual author in relation with his work, to reflections on a collective authorship that allows the presence of the author in multiple forms. Our proposal focuses on the erudition work, criticism and retrieval of historical sources performed in the 18th century in Spain. Many clerics and seculars, scholars or amateurs, statesmen or mere advantaged scribblers assumed the role of shadow authors and contributed to a collective effort of national renewal featured by the struggle between tradition and innovation. The new rulers led the reformist agenda program with the collaboration of literates and of certain institutions created to foster progress and common good, among them the Royal Academies. Our work will concentrate on the projects of compilation of historical sources that were promoted within the Royal Academy of History. Dictionaries, repertoires and instrumental collections approach us to the nature, justification, objectives and milestones of a collective authorship model that half-hidden, certainly represents the cultural practices of the Spanish Age of Enlightenment.
Equivalence of different methods for slant and skew corrections in word recognition applications (2001)

Normalization of slant and skew is often used in processing a word image before recognition. In this paper, we prove the theoretical equivalence of different methods for slant and skew corrections. In particular, we show that correcting first for skew by rotation and then for slant by a shear transformation in the horizontal direction is equivalent to first correcting for slant by a shear transformation in the horizontal direction and then for skew by a shear transformation in the vertical direction. Our proof can be easily modified to prove equivalence of other methods for correcting the slant and skew.
P2‐157: Serine422 phosphorylation of tau protein by oxidative stress via c‐Jun N‐terminal kinase (JNK) activation (2008)

Mechanisms of tau hyperphosphorylation have not yet been well understood. In order to clarify mechanisms of tau protein abnormal phosphorylation, we have investigated quantitative changes of phosphorylated tau proteins and various kinases, such as JNK and glycogen synthase kinase-3beta (GSK-3beta), in culture cells under oxidative stress condition. Nickel chloride was added to culture media of 4 repeat tau protein overexpressing HEK293 cells to produce chemical oxidative stress condition, and then those cells were harvested at regular time intervals. Those samples were analyzed by western blotting, and were checked the quantitative changes of phosphorylated tau proteins and activated kineses. Twenty-four hours after addition of nickel chloride, there was an increased activation of JNK and related kinases in the cell lysate, and at the same time, we detected an increased amount of phosphorylated serine422 in tau proteins. It is known that tau proteins are hyperphosphorylated by kinases which are activated under various stress conditions or an accumulation of amyloid proteins. Our results indicate JNK is one of important kinases for tau hyperphosphorylation under oxidative stress condition.

A Model for Estimating the Dielectric Constant of Soybeans (1985)

THE dielectric properties of soybeans representing ten cultivars were measured at 24 C over the moisture range from 6 to 24%, wet basis, at frequencies of 20, 300, and 2450 MHz. Mean values over the ten cultivars for the dielectric constants at each frequency and moisture content, along with mean values for moisture content and bulk density of the soybeans, were used in the development of a model that predicts the dielectric constant of soybeans as a function of frequency, moisture content, and bulk density with an average error of less than 3% over this range of frequencies and moisture contents. Variation of bulk density and seed density of the soybeans with moisture content was much less than that of corn and wheat over comparable ranges of moisture content.

Quantum wells with atomically smooth interfaces (2002)

By a cleaved-edge overgrowth method with molecular beam epitaxy and a (110) growth-interrupt anneal, we have fabricated a GaAs quantum well exactly 30 monolayers thick bounded by atomically smooth AlGaAs heterointerfaces without atomic roughness. Microphotoluminescence imaging of this quantum well indeed shows spatially uniform and spectrally sharp emission over areas of several tens of microns in extent. By adding a fractional GaAs monolayer to our quantum well we are able to study the details of the atomic step-edge kinetics responsible for flat interface formation.
Cross-language specialization in phonetic processing: English and Hindi perception of /w/-/v/ speech and nonspeech (2011)

This study examined the perceptual specialization for native-language speech sounds, by comparing native Hindi and English speakers in their perception of a graded set of English /w/-/v/ stimuli that varied in similarity to natural speech. The results demonstrated that language experience does not affect general auditory processes for these types of sounds; there were strong cross-language differences for speech stimuli, and none for stimuli that were nonspeech. However, the cross-language differences extended into a gray area of speech-like stimuli that were difficult to classify, suggesting that the specialization occurred in phonetic processing prior to categorization.
Translational Research on Ocular Surface Reconstruction Using Oral Mucosal Epithelial Cell Sheets (2014)

Ocular surface reconstruction using autologous oral mucosal epithelial cell sheets has drastically changed the treatment of limbal stem-cell deficiency. The morphological and functional characteristics of oral mucosal epithelial cell sheets are similar to those of normal corneal epithelium. Ocular surface reconstruction can prevent potential problems associated with limbal transplantation, including immune rejection and donor tissue shortages. Thus far, ocular reconstruction using epithelial cell sheets has been limited to clinical research. Although the effectiveness and safety of this surgical approach have been confirmed to some extent, efforts to make its use more widespread are required. "Translational research" refers to the process of developing a new treatment based on basic research findings with useful practical applications in the field of health care. Medical centers for translational research are required to promote translational research in academic institutes. The Pharmaceutical Affairs Law was revised to promote technologies in the field of regenerative medicine in Japan. This article reviews translational research of ocular surface reconstruction using oral mucosal epithelial cell sheets.
TITAN: Integrated network management in tactical mobile ad hoc networks (2012)

Network management represents one of the most challenging activities in tactical mobile ad hoc networks due to the need for rapid planning and configuration to support a given mission, in the face of large variability in wireless network performance and unpredictable conditions. Traditionally, independent tools, such as network planning and configuration, fault and performance management, and middleware have been designed to provide comprehensive network management capabilities. However, the lack of any integration between these tools often results in sub-optimal or conflicting network actions, conducting to inadequate network performance. More importantly, state of the art network management tools do not incorporate the mission intent into autonomous network management activities. This paper describes the TITAN (Tactical Information Technologies for Assured Networks) NM (Network Manager), an integrated network management tool that orchestrates and coordinates its actions such that network planning, configuration, fault response and performance adaptation take place seamlessly and coherently, on the basis of the mission intent. This ensures optimized network operations that achieve the intent of the mission. We present performance evaluation results for the TITAN NM in field experiments performed during C4ISR 2011 On-The-Move exercises at Fort Dix, NJ.
A wide-range all-digital duty-cycle corrector with output clock phase alignment in 65nm CMOS technology (2011)

A wide-range all-digital duty-cycle corrector (ADDCC) with output clock phase alignment is presented in this paper. The proposed ADDCC can correct the duty-cycle error of the input clock to 50% duty-cycle. The acceptable duty-cycle range and frequency range of input clock is from 20% to 80% and from 250MHz to 1GHz, respectively. The proposed ADDCC is implemented on a standard performance 65nm CMOS process, and the power consumption is 1.52mW at 250MHz and 5.83mW at 1GHz, respectively.
Electro-Modulation of Plasmonic and Photonic-Metamaterial Structures (2010)

Sequential venous anastomosis design to enhance patency of arterio-venous grafts for hemodialysis (2016)

Arterio-venous grafts (AVGs), the second best option as long-term vascular access for hemodialysis, face major issues of stenosis mainly due to development of intimal hyperplasia at the venous anastomosis which is linked to unfavorable hemodynamic conditions. We have investigated computationally the utility of a coupled sequential venous anastomotic design to replace conventional end-to-side (ETS) venous anastomosis, in order to improve the hemodynamic environment and consequently enhance the patency of AVGs. Two complete vascular access models with the conventional and the proposed venous anastomosis configurations were constructed. Three-dimensional, pulsatile blood flow through the models was simulated, and wall shear stress (WSS)-based hemodynamic parameters were calculated and compared between the two models. Simulation results demonstrated that the proposed anastomotic design provides: (i) a more uniform and smooth flow at the ETS anastomosis, without flow impingement and stagnation point on the artery bed and vortex formation in the heel region of the ETS anastomosis; (ii) more uniform distribution of WSS and substantially lower WSS gradients on the venous wall; and (iii) a spare route for the blood flow to the vein, to avoid re-operation in case of stenosis. The distinctive hemodynamic advantages observed in the proposed anastomotic design can enhance the patency of AVGs.
A Drift-Compensating Novel Deep Belief Classification Network to Improve Gas Recognition of Electronic Noses (2020)

Electronic nose (E-nose) systems have a good effect on the identification of distinct odours. However, the properties of chemical gas sensors indicate that ageing, poisoning, fluctuation of environmental conditions (moisture, temperature, etc.) and a lack of fabrication repeatability, etc. have a large impact on the sensitivity and accuracy of sensors, which leads to sensor data drift. Although previous studies have indicated the feasibility and validity of deep learning in drift compensation of gas sensor data, the actual performances of these deep learning models are less impressive compared with some existing methods. Thus, we intend to further explore a novel deep learning model for drift compensation for E-noses. In this paper, we investigate the drift compensation effect of E-nose data based on a deep belief network (DBN) and constructed a Gaussian deep belief classification network (GDBCN) model by cascading a Gaussian-Bernoulli restricted Boltzmann machines based DBN with a softmax classifier layer to compensate for sensor drift at the decision level. The merits of our method are as follows: 1) it is a unified classification model for drift auto-compensation at the decision level rather than a feature extractor; 2) it couples unsupervised and supervised techniques by modelling the intrinsic distribution of the data from different domains in an unsupervised manner and fine-tunes the model parameters by leveraging the label information of the source domain; 3) the supervised fine-tuning process for the coupled GDBCN model fits well with the nature of the supervised task and guarantees that the parameters of the DBN will be useful for classification; 4) the GDBCN model is a classification model and thus automatically compensates for drift without manually setting specific model rules for domain alignment before classification. Experimental results on real sensor datasets demonstrate the effectiveness and superiority compared with several existing control methods.
