Abstract The results of in-situ measurements of optical absorption and electrical conductivity in C60/C70 (9/1) film during electrochemical reduction in a cell using solid polymer electrolyte are reported. The drastic change of absorbance and the increase of conductivity upon Li doping were obtained and the results are discussed.
GENE-15. CAVATICA- A PEDIATRIC GENOMIC CLOUD EMPOWERING DATA DISCOVERY THROUGH THE PEDIATRIC BRAIN TUMOR ATLAS (2017)

CAVATICA (cavatica.org) was developed to address the lack of open access large scale pediatric cancer genomic datasets for the research community. As the first of its kind pediatric genomic portal, CAVATICA empowers data upload, sharing, and creation of pipelines, data, algorithms, visualizations, and hypotheses. Building upon the need for pediatric brain tumor genome dataset, the Pediatric Brain Tumor Atlas was founded in late 2016, a concerted multi-institution effort by the Children’s Brain Tumor Consortium (CBTTC) and the Pacific Pediatric Neuro-Oncology Consortium. The goal of the Pediatric Brain Tumor Atlas is to characterize and deeply profile a newly defined cohort of brain tumor samples across diverse histopathologies via a combination of whole exome sequencing, whole genome sequencing, RNA sequencing and limited proteomic analysis. CAVATICA is positioned to support integrative analysis and open access to data alongside shared computation and algorithms that empower users to further integrate and analyze their own uploaded data. Additionally, CAVATICA provides further portal access to dbGaP approved users to TCGA and other NCI datasets hosted by the NCI’s Cancer Genomics’ Cloud. By committing to the rapid release of these large pediatric brain tumor data and their deposition in CAVATICA’s cloud-based environment supporting shared pipelines, computation, and visualizations, PNOC and the CBTTC’s collaborating membership are seeking to provide a centralized, collaborative rapid discovery environment for researchers to engage new discovery and data reuse. An additional component of this research application ecosystem, the data generated by the Pediatric Brain Tumor Atlas within CAVATICA will also link with PedcBioPortal (PedcBioPortal.org), a data visualization and analysis application further integrating across additional public and deposited datasets. In summary, CAVATICA will empower data discovery and hypothesis generation for the Pediatric Brain Tumor Atlas.
From Molecular Gallium and Indium Siloxide Precursors to Amorphous Semiconducting Transparent Oxide Layers for Applications in Thin‐Film Field‐Effect Transistors (2012)

Abstract The syntheses, structural characterization, and thermal degradation of a series of the new indium and gallium siloxide dimers [{Me 2 In(OSiEt 3 )} 2 ] ( 1 ), [{Me 2 Ga(OSiEt 3 )} 2 ] ( 2 ), [{Me 2 In(OSi(O t Bu) 3 )} 2 ] ( 3 ), [{Me 2 Ga(OSi(O t Bu) 3 )} 2 ] ( 4 ), and In[OSi(O t Bu) 3 )] ( 5 ) is reported. Compounds 1 – 4 are readily accessible by facile Brönsted reaction of InMe 3 or GaMe 3 with the corresponding silanols Et 3 SiOH and ( t BuO) 3 SiOH, respectively. Compound 5 could be obtained by analogous protolysis of [In{N(SiMe 3 ) 2 } 3 ] with an excess amount of ( t BuO) 3 SiOH. The suitability of 1 – 5 to serve as molecular precursors for low‐temperature synthesis of amorphous indium and gallium oxide for electronic applications was probed. Thus their thermal degradation was studied by Thermogravimetric/differential thermogravimetry analysis (TGA/DTG). Compounds 1 – 4 were decomposed under dry synthetic air (20 % O 2 , 80 % N 2 ) at low temperature to yield amorphous indium oxide and gallium oxide particles, respectively. In contrast, thermal degradation of 5 affords amorphous indium silicate. All of these products were analyzed by multiple techniques including powder X‐ray diffraction analysis (PXRD) , transmission electron microscopy (TEM), and energy dispersive X‐ray spectroscopy (EDX). Thin‐film field‐effect transistors (FETs) could be fabricated through spin‐coating of silicon‐wafers with solutions of 1 in toluene and subsequent calcination under dry synthetic air at 350 °C. These films exhibit very good FET performance with a field‐effect mobility of 3.0×10 −1 cm 2 V −1 s and an on/off current ratio of 10 8 .
Discharge Characteristics of Laser-Electric Hybrid Thrusters (2004)

A fundamental study on two types of novel laser-electric hybrid thrusters, a laser-assisted pulsed-plasma thruster and a laser-assisted electrostatic thruster, in which a laser-induced plasma was induced through laser beam irradiation onto a solid target and accelerated by electrical means instead of direct acceleration only by using a laser beam, was conducted to elucidate its discharge and acceleration characteristics. In the laser-assisted PPTs with 8.65 J discharge energy, the maximum current reached about 8000 A. Also, it was shown that the impulse bit and specific impulse linearly increased. While, coupling coefficient decreased with energy showing maximum value (20.8 μNsec/J) at 0 J, or in a pure laser ablation case. Thrust efficiency slightly decreased with energy ranging 0 to 1.4 J and then increased linearly with energy from 1.4 J to 8.6 J. At 8.65 J operation, impulse bit of 38.1 μNsec, specific impulse of 3791 sec, thrust efficiency of 8 %, and coupling coefficient of 4.3 μNsec/J were obtained. In the laser-assisted electrostatic thruster, energy distributions of accelerated ions were measured by a Faraday cup. A time-of-flight measurement was also conducted for ion velocity measurement. It was shown that an acceleration electrode with positive potential was more effective than that with negative potential for positive-ion acceleration in laser induced plasma, or pulsed plasma, in which ions were induced with the Coulomb explosion following electrons.
Deep-Learning Quantitative Structural Characterization in Additive Manufacturing (2023)

With a goal of accelerating fabrication of additively manufactured components with precise microstructures, we developed a method for structural characterization of key features in additively manufactured materials and parts. The method utilizes deep learning based on an image-to-image translation conditional Generative Adversarial Neural Network architecture and enables fast and incrementally more accurate predictions of the prevalent geometric features, including melt pool boundaries and printing induced defects visible in etched optical images. These structural details are heterogeneous in nature. Our method specifies the microstructure state of an additive built via statistical distribution of structural details, based on an ensemble of collected images. Extensions of the method are proposed to address Artificial Intelligence implementation of developed machine learning model for in real time control of additive manufacturing.
Has the incidence of primary gastric lymphoma increased? (1989)

Various reports from the surgical and gastroenterologic literature have stated that the incidence of primary gastric lymphoma has increased. Other reports have claimed that this is a relative increase or represents referral center bias. The current study was designed to determine if the incidence of primary gastric lymphoma has increased in the community hospital setting. A total of 147 cases of gastric neoplasms were reviewed over a 10-year study period. The cases were divided into two 5-year periods, i.e., 1978-82 and 1983-87. There were two new cases (2.8%) of primary gastric lymphoma in the period 1978-82 and 11 new cases (19%) in the period 1983-87. The difference in proportion of primary gastric lymphoma between these two time periods was statistically significant (P = 0.01 by chi-square analysis). This increased incidence of primary gastric lymphoma is difficult to explain, but it must be recognized by surgeons and endoscopists.
Processing of low-intensity CCD images for temperature mapping in industrial processes (2004)

The temperature-mapping system presented is based on a grayscale CCD camera, rotating near infrared filters and an image processing software which is used for thermal imaging of heated metal parts in heat treatment processes (plasma nitriding). Due to relatively low process temperatures of about 300°C - 500°C the received light intensity of the glowing metal parts is very weak. The quality of these images can be improved by applying modern image processing filter methods. A precondition for a correct application of these denoising filters is an exact noise characterisation of the imaging system. A camera characterisation procedure based on the photon transfer technique and the system transfer function is presented. Based on these results, examples for density and intensity estimations of Poisson noise images with multiresolution methods (Platelets) are presented. The results are used to improve image quality and measurement accuracy of CCD based thermal images.
Comparison of Bovine Collagen Xenografts to Autografts in the Rabbit (1991)

The use of bovine tendon as a xenograft material in humans is attractive because of its ready availability and favorable mechanical characteristics. Previous research has shown that the fibroblasts and some extracellular proteoglycans and glycoproteins, not the collagen matrix itself, in bovine tendon are primarily responsible for its antigenicity. Various attempts have been made to decrease the antigenicity of these grafts. A chloroform/methanol (CM) extraction procedure has been developed that selectively removes the fibroblasts from bovine tendon without destroying the collagen matrix. The mechanical, immunologic, and local host tissue responses to these grafts were compared to autografts and to untreated and glutaraldehyde-treated bovine tendon xenografts. The humoral immune response to a purified bovine Type I collagen product was also studied. The central two-thirds of a rabbit Achilles tendon were replaced with a reversed autograft or an experimental graft. Histologic examination of one- and two- week specimens showed an acute inflammatory response to all grafts. Untreated grafts stimulated a severe inflammatory response and were almost completely resorbed by two weeks. Glutaraldehyde-treated grafts were encapsulated. Cellular repopulation was minimal and inflammatory response was more persistent than in the autograft and CM groups. Inflammatory response to CM-treated grafts was similar to that of autografts. The CM grafts repopulated rapidly with host cells. The mechanical strength of CM grafts was equal to autograft controls at 12 weeks. The mechanical strength of untreated and glutaraldehyde-treated grafts was significantly lower. Measurement of the humoral immune response to these grafts was conducted in an independent group of animals using an enzyme-linked immunosorbent assay. A significant antibody response to untreated, glutaraldehyde-fixed, and CM-treated grafts was detected at 30 days. Antibody titers to glutaraldehyde-fixed and untreated grafts remained elevated at 60 and 90 days. In the CM group, antibody titers decreased to the level of autograft controls by 90 days. No significant antibody response was detected toward purified bovine Type I collagen.
A first step on the path to automated flight reservations (2002)

A common benefit for airline employees is greatly reduced fares on company commercial flights. Employees and their eligible dependents may "list on" (book) a flight at the reduced fare, however they may board only if non-revenue seats are available when the flight departs. Listed passengers frequently call reservation agents as the departure date approaches to determine the load on the airplane to predict the chance of obtaining a seat. This paper describes an automated prototype interactive voice system that has been designed to improve the efficiency of agent pools by executing routine airline employee flight listings and flight load inquiries. The system may be integrated with human agent pools so that callers can be transferred when having difficulty with the automated call flow. This system is a first step in automating revenue-bearing flight reservations.
Trading services in open distributed environments (1998)

The current development of computing and telecommunication environments aims towards interoperability across separate platforms and organisations in a world-wide fashion. Interoperability means that software components can be exploited from arbitrary computers in such a way that the service semantics is preserved. The mechanisms supporting interoperability at the application level must mask heterogeneity of the compound computing environment. The term `open distributed processing&amp;apos; does not currently have a single, commonly accepted interpretation. Therefore, the main system architecture models are critically analysed in order to contrast the facilities for interoperation in each model. The focus of this dissertation is on the problems arising when the interoperating computing systems are controlled by autonomous organisations, i.e., problems of federated systems. Federations between sovereign systems involve exploitation of open interfaces and run-time information about the system fa...

Studies on contact toxicity-Part IV (2014)

The use of starch and a mixture of glue and potassium dichromate as pretreatment for the enhancement of the residual activity of DDT has been investigated using mosquitoes, Cluex fatigans Weid. and flies, Musca nebulo Linn. The DDT deposits were derived either from an emulsifiable concentrate or a water dispersible powder concentrate. As substrate, cement, brick and mud surfaces were investigated both as they were in the lime-washed conditions. Pretreatment with glue-dichromate considerably enhanced the residual activity of DDT against both the species of insects on all the three surfaces and proved very much superior to pretreatment with starch. The deposits derived from DDT emulsion showed residual activity for a longer period than those derived from DDT water dispersible powder on mud surfaces pretreated with glue-dichromate.
Employing Hybrid Lennard-Jones and Axilrod-Teller Potentials to Parametrize Force Fields for the Simulation of Materials’ Properties (2021)

The development of novel materials has challenges besides their synthesis. Materials such as novel MXenes are difficult to probe experimentally due to their reduced size and low stability under ambient conditions. Quantum mechanics and molecular dynamics simulations have been valuable options for material properties determination. However, computational materials scientists may still have difficulty finding specific force field models for their simulations. Force fields are usually hard to parametrize, and their parameters' determination is computationally expensive. We show the Lennard-Jones (2-body interactions) combined with the Axilrod-Teller (3-body interactions) parametrization process' applicability for metals and new classes of materials (MXenes). Because this parametrization process is simple and computationally inexpensive, it allows users to predict materials' behaviors under close-to-ambient conditions in molecular dynamics, independent of pre-existing potential files. Using the process described in this work, we have made the Ti2C parameters set available for the first time in a peer-reviewed work.
Study on the Fast Training Algorithm of Iteratively Re-weighted Least Squares Support Vector Machine (2010)

Iteratively reweighted method is an important approach to improve the robustness of least squares support vector machine(LS-SVM).However,the reweighting and retraining procedure demands a lot of computational time,which makes it impossible for practical applications.In this paper,the iteratively reweighted least squares support vector machine(IRLS-SVM)was studied.An improved training algorithm of IRLS-SVM was proposed.It is based on novel numerical method,and can effectively reduce the computational complexity of IRLS-SVM.Three different weight functions were implemented in the IRLS-SVM.Experiments on simulated instances and real-world datasets demonstrate the validity of this algorithm.Meanwhile,the results reveal that different weight function may require different computational time for the fast training algorithm of IRLS-SVM.
Human Matching Behavior in Social Networks: An Algorithmic Perspective (2012)

We argue that algorithmic modeling is a powerful approach to understanding the collective dynamics of human behavior. We consider the task of pairing up individuals connected over a network, according to the following model: each individual is able to propose to match with and accept a proposal from a neighbor in the network; if a matched individual proposes to another neighbor or accepts another proposal, the current match will be broken; individuals can only observe whether their neighbors are currently matched but have no knowledge of the network topology or the status of other individuals; and all individuals have the common goal of maximizing the total number of matches. By examining the experimental data, we identify a behavioral principle called prudence, develop an algorithmic model, analyze its properties mathematically and by simulations, and validate the model with human subject experiments for various network sizes and topologies. Our results include i) a 1/2-approximate maximum matching is obtained in logarithmic time in the network size for bounded degree networks; ii) for any constant ε > 0, a (1 - ε)-approximate maximum matching is obtained in polynomial time, while obtaining a maximum matching can require an exponential time; and iii) convergence to a maximum matching is slower on preferential attachment networks than on small-world networks. These results allow us to predict that while humans can find a "good quality" matching quickly, they may be unable to find a maximum matching in feasible time. We show that the human subjects largely abide by prudence, and their collective behavior is closely tracked by the above predictions.
Evaluation of the contribution of cytochrome P450 3A4 to human liver microsomal bupropion hydroxylation. (2001)

The purpose of this investigation was to evaluate the role of cytochrome P450 (CYP) 3A4 in human liver microsomal bupropion (BUP) hydroxylation. Across the BUP concentration range of 0.075 to 12 mM, cDNA-expressed CYP3A4 demonstrated BUP hydroxylase activity only when incubated with concentrations > or =4 mM. When assayed at 12 mM BUP, cDNA-expressed CYP3A4 catalyzed BUP hydroxylation at a 30-fold lower rate than cDNA-expressed CYP2B6 (0.2 versus 7 pmol/min/pmol of P450). Among a panel of 16 human liver microsomes (HLMs), BUP hydroxylase activity varied 80-fold when assayed at 500 microM and did not strongly correlate with testosterone 6beta-hydroxylase activity when assayed at 250 microM testosterone (r(2) = 0.39), nor with CYP3A4 protein expression. A selective CYP3A4 inhibitor, troleandomycin (TAO), did not significantly alter rates of BUP hydroxylation when assayed in a moderate activity HLM at 10 to 2000 microM BUP, as reflected by a similarity in the kinetic parameters of BUP hydroxylation in the absence or presence of TAO. In addition, the same range of TAO concentrations (0.025-100 microM) that inhibited testosterone 6beta-hydroxylation in a concentration-dependent manner (46-81%) in pooled HLMs produced negligible inhibition (7%) of BUP hydroxylation when assayed at 500 microM BUP. These results suggest that CYP3A4 does not significantly catalyze BUP hydroxylation. Furthermore, these results complement recent data supporting selectivity of BUP hydroxylation for CYP2B6 at 500 microM BUP.
Signal adaptive postprocessing for blocking effects reduction in JPEG image (2002)

A postprocessing algorithm is proposed to reduce the blocking artifacts of joint photographic experts group (JPEG) decompressed images. The reconstructed images from JPEG compression produce noticeable image degradation near the block boundaries, in particular, for highly compressed images because each block is transformed and quantized independently. The reduction of these blocking effects has been an essential issue for high quality visual communications. The proposed postprocessing algorithm reduces these blocking artifacts efficiently. A comparison study between the proposed algorithm and other postprocessing algorithms is made by computer simulation with several JPEG images. These simulation results show that the proposed algorithm reduces the blocking artifacts significantly in the subjective and objective views.
Effect of deformation and root pruning of eucalyptus cuttlings on the growth in the field. (2009)

The measurements of both CEA and cholesterol concentrations in ascites give additional specific information about peritoneal carcinomatosis and can therefore be a useful adjunct to cytology-in particular, in inconclusive cases.
Effects of ectoine containing nasal spray and eye drops on symptoms of seasonal allergic rhinoconjunctivitis (2021)

The study suggests that ectoine is effective in reducing nasal and ocular symptoms associated with ARC. Being a natural, bacteria derived stress protection molecule functioning by a physical mode of action, it therefore represents an alternative nonpharmacological treatment option.
Interactive video as a teaching medium (1991)

In the last article in her four-part series on computers in nursing, Nicola Eaton focuses on the use of interactive video in nurse education. While acceptability of computer technology currently runs high, the full potential of this medium will not be realised until manufacturers, program designers and educationalists learn to share their ideas and concentrate on the outcome of their efforts.
