Fungal Antigens Expressed during Invasive Aspergillosis (2005)

Rabbits that had been infected intravenously with conidiospores of Aspergillus fumigatus were used as sources of antibody for screening a lambda phage cDNA expression library. The cDNA was derived from A. fumigatus mRNA that had been extracted from newly formed, germling hyphae. Thirty-six antigens were identified using antisera from six rabbits. Though many of these antigens were expected to be intracellular proteins because their genes did not encode a signal sequence, the antisera showed consistently a stronger immunoblot reaction with a cell fraction enriched for the fungal cell wall than with a fraction of predominantly intracellular components. Antibodies to eight antigens, including the glycosylhydrolase Asp f 16, were produced by more than one rabbit. In current vaccine studies, Asp f 16 is the only single antigen which has been reported to be capable of inducing protection against invasive aspergillosis in mice. Enolase and Aspergillus HSP90 were detected also; their homologues in Candida albicans have been tested as vaccines and have been reported to provide a partially protective response against invasive candidiasis in mice. The Aspergillus antigens reported here may have value both in diagnostic tests for different forms of aspergillosis and as vaccine candidates for protection against invasive disease.

Equilibrium, kinetic and photoaffinity labeling studies of daunomycin binding to P‐glycoprotein‐containing membranes of multidrug‐resistant Chinese hamster ovary cells (1989)

The binding of daunomycin and its Bolton-Hunter derivative iodomycin to plasma membranes isolated from multidrug-resistant Chinese hamster ovary cells (CHO B30) and their drug-sensitive parents (B1) was investigated. The thermodynamics and kinetics of equilibrium binding monitored by fluorescence titrations and temperature-jump relaxation spectrometry were compared with the specificity of covalent photolabeling with [3H]daunomycin and [125I]iodomycin. The facts that the uptake of anthracycline from aqueous solution into the CHO membranes was not accompanied by any substantial increase of fluorescence anisotropy nor by any spectral shift of the fluorescence emission spectrum and that the partition ratio into the membrane was 20-30-fold higher when compared to a lecithin bilayer, provided evidence that the non-covalent drug binding sites are constituted by polar protein domains without any substantial contribution from the surrounding lipids. Photoaffinity labeling with nanomolar concentrations of anthracycline and equilibrium binding curves independently showed that a 150-170-kDa plasma membrane glycoprotein (P-glycoprotein), whose overexpression is the major difference between B1 and B30 membranes, provides the binding sites of highest affinity for daunomycin and iodomycin (K approximately equal to 4 x 10(7) M-1). Comparison of photolabeling and equilibrium data suggested that the same binding sites on P-glycoprotein were most probably being monitored. The photolabeling of P-glycoprotein by iodomycin was inhibited in a dose-dependent manner by other compounds to which multi-drug-resistant cells are either resistant or collaterally sensitive with the following orders of effectiveness: vinblastine greater than verapamil greater than nitrendipine greater than daunomycin much greater than colchicine. Temperature-jump experiments covering the time range of 1 microseconds to 1 s revealed a single concentration-dependent relaxation time of 10-30 microseconds. The association of daunomycin with its binding sites in the membranes was found to be a diffusion-controlled process with kon rates of 2-4 X 10(9) M-1 s-1. Therefore, the selectivity of drug binding was entirely reflected in the dissociation rates.
Size Matters and How You Measure It: A Gram-Negative Antibacterial Example Exceeding Typical Molecular Weight Limits (2019)

Monobactam antibiotic <b>1</b> is active against Gram-negative bacteria even though it has a higher molecular weight (MW) than the limit of 600 Da typically applied in designing such compounds. On the basis of 2D NMR data, the compound is able to adopt a compact conformation. The dimensions, projection area, and dipole moment derived from this conformation are compatible with porin permeation, as are locations of polar groups upon superimposition to the crystal structure of ampicillin bound to <i>E. coli</i> OmpF porin. Minimum inhibitory concentration (MIC) shifts in a porin knock-out strain are also consistent with <b>1</b> predominately permeating through porins. In conclusion, we describe a carefully characterized case of a molecule outside default design parameters where MW does not adequately represent the 3D shape more directly related to permeability. Leveraging 3D design criteria would open up additional chemical space currently underutilized due to limitations perceived in 2D.
Performance evaluation of generalized selection combiners (GSC) over slow fading channels with estimation errors (2009)

In this paper, we analyze the impact of channel estimation error on the capacity statistics and the symbol error rate (SER) for generalized selection combiners (GSC) systems. The channels are assumed slow flat Rayleigh fading and spatially independent. The capacity statistics moment generating function(MGF), complementary cumulative distribution function (CDF) and probability density function (PDF) are valid for arbitrary number of receive antennas. Moreover, exact closed-form expressions for M-PAM/PSK/QAM are derived. As expected, the channel estimation error has significant impact on the system performance.
The Compact Support Neural Network (2021)

Neural networks are popular and useful in many fields, but they have the problem of giving high confidence responses for examples that are away from the training data. This makes the neural networks very confident in their prediction while making gross mistakes, thus limiting their reliability for safety-critical applications such as autonomous driving and space exploration, etc. This paper introduces a novel neuron generalization that has the standard dot-product-based neuron and the radial basis function (RBF) neuron as two extreme cases of a shape parameter. Using a rectified linear unit (ReLU) as the activation function results in a novel neuron that has compact support, which means its output is zero outside a bounded domain. To address the difficulties in training the proposed neural network, it introduces a novel training method that takes a pretrained standard neural network that is fine-tuned while gradually increasing the shape parameter to the desired value. The theoretical findings of the paper are bound on the gradient of the proposed neuron and proof that a neural network with such neurons has the universal approximation property. This means that the network can approximate any continuous and integrable function with an arbitrary degree of accuracy. The experimental findings on standard benchmark datasets show that the proposed approach has smaller test errors than the state-of-the-art competing methods and outperforms the competing methods in detecting out-of-distribution samples on two out of three datasets.

Visual Diagnosis of Tree Boosting Methods (2017)

Tree boosting, which combines weak learners (typically decision trees) to generate a strong learner, is a highly effective and widely used machine learning method. However, the development of a high performance tree boosting model is a time-consuming process that requires numerous trial-and-error experiments. To tackle this issue, we have developed a visual diagnosis tool, BOOSTVis, to help experts quickly analyze and diagnose the training process of tree boosting. In particular, we have designed a temporal confusion matrix visualization, and combined it with a t-SNE projection and a tree visualization. These visualization components work together to provide a comprehensive overview of a tree boosting model, and enable an effective diagnosis of an unsatisfactory training process. Two case studies that were conducted on the Otto Group Product Classification Challenge dataset demonstrate that BOOSTVis can provide informative feedback and guidance to improve understanding and diagnosis of tree boosting algorithms.
Multi-Epitope-Based Vaccines for Colon Cancer Treatment and Prevention (2021)

New Flow-Through Wind-Tunnel Balance for Retropropulsion Testing (2022)

Supersonic retropropulsion, or the use of retrorockets starting at supersonic conditions, is an enabling technology for large-scale human Mars lander vehicle concepts. A new flow-through balance was designed and fabricated to support an upcoming retropropulsion test campaign at the NASA Langley Research Center Unitary Plan Wind Tunnel. The balance employs membranes in place of bellows, which have historically been used, and passes the flow-through load-bearing parts of the balance. Flow through the balance is optimized via the addition of flow guides, which are manufactured as separate parts, and attached to the balance. Calibration of this new flow-through balance demonstrates that it can suitably characterize the load and pressure ranges it was designed for, which provides aerodynamicists a new tool to directly measure supersonic retropropulsion performance of powered descent vehicles.
Silica-based low loss and high extinction ratio 8/spl times/8 thermo-optic matrix switch with path-independent loss arrangement using double Mach-Zehnder interferometer switching units (1996)

We describe a low loss and high-extinction ratio 8/spl times/8 thermo-optic matrix switch with a reduced 8 stage configuration composed of silica-based planar lightwave circuits. The average insertion loss and the extinction ratio were 5.1 dB and 60.3 dB, respectively.
Effect of plasma pooling on the International Sensitivity Index of prothrombin time systems (1998)

Guidelines set by the World Health Organization (WHO) state that in order to calibrate a prothrombin time system for International Sensitivity Index (ISI), freshly prepared specimens from 20 normal individuals and 60 patients receiving coumarin are required. These numbers are required to obtain a precise value of the calibration line slope when there is considerable scatter of individual data about the regression line. The scatter can be reduced by pooling individual plasma samples. In the present study, four pooled plasmas were prepared, one from 20 normal individuals and three from three groups of 30 patients receiving treatment with long-term oral anticoagulants. Prothrombin times were determined with four thromboplastins, HepatoQuick (rabbit thromboplastin combined with adsorbed plasma), Recombiplastin (recombinant human thromboplastin), Thromborel-S (human placenta), and Thromboplastin-C Plus (rabbit brain). Calibration line slopes were calculated for the six possible combinations of thromboplastins using the set of all individual plasma samples and the set of four pooled plasmas. In most comparisons, the WHO calibration model was appropriate, i.e. the line calculated for the patients' samples passed through the mean of the normals. The calibration line slopes obtained with the set of four pooled plasmas did not differ by more than 5% from the corresponding slopes calculated with the original individual plasmas. For some combinations of thromboplastins non-linear relations were observed both with the individual plasmas and with the pooled plasmas. We conclude that pooling individual plasmas does not significantly change the calibration relation between prothrombin times determined with the original individual plasmas. Freshly pooled plasmas can be used to determine the ISI of prothrombin time systems with an acceptable degree of precision.
Technical, Economic, and Environmental Comparison of Closed-Loop Recycling Technologies for Common Plastics (2023)

Over 400 million metric tons of plastic waste are generated globally each year, resulting in pollution and lost resources. Recycling strategies can recapture this wasted material, but there is a lack of quantitative and transparent data on the capabilities and impacts of these processes. Here, we develop a data set of material quality, material retention, circularity, contamination tolerance, minimum selling price, greenhouse gas emissions, energy use, land use, toxicity, waste generation, and water use metrics for closed-loop polymer recycling technologies, including mechanical recycling and solvent-based dissolution of polyethylene, polyethylene terephthalate (PET), and polypropylene, as well as enzymatic hydrolysis, glycolysis, and vapor methanolysis of PET. Mechanical recycling and PET glycolysis display the best economic (9%–73% lower than competing technologies) and environmental (7%–88% lower) performances, while dissolution, enzymatic hydrolysis, and methanolysis provide the best recyclate material qualities (2%–27% higher). We identify electricity, steam, and organic solvents as top process contributors to these metrics and apply sensitivity and multicriteria decision analyses to highlight key future research areas. The estimates derived in this work provide a quantitative baseline for comparing and improving recycling technologies, can help reclaimers identify optimal end-of-life routes for given waste streams, and serve as a framework for assessing future innovations.

Illumination Normalization using Quotient Image-based Techniques (2008)

This chapter discussed a method of synthesizing an illumination normalized image using Quotient Image-based techniques. Facial appearance contains diffuse reflection, specular reflection, attached shadow and cast shadow. Our Quotient Image-based technique classifies facial appearance into four components using basis images representing diffuse reflection on a generic face. Our method is able to obtain high identification performance on the Yale Face Database B and on a real-world database, using only a single image for each individual in training.
Temporal evolution of whistler growth in a cold plasma injection experiment (1984)

Using a simple time dependent cold plasma density model and assuming a typical ambient radation belt environment, the authors study the evolution of the whistler mode turbulence and particle precipitation in a cold plasma release experiment similar to one which may be conducted as part of the AMPTE program. It is known from earlier work that the release of cold lithium ions can significantly lower the critical energy E sub c above which the resonant radiation belt electrons can pitch angle scatter. They study the time evolution of the one pass gain factor for a whistler wave packet and find that for parameters accessible to AMPTE type experiments the gain factor is large enough to ensure strong whistler turbulence and strong pitch angle diffusion of radiation belt particles with energies in the range between the ambient value of E sub c and the reduced value of E sub c. Estimates for the total power input to the ionospheric footprint of the release are of the order of an erg/sq cm/sec. This precipitated energy should produce a patch of visible aurora. This effect should also persist for many hours. (Author)
Topographically-Designed Triboelectric Nanogenerator via Block Copolymer Self-Assembly (2014)

Herein, we report a facile and robust route to nanoscale tunable triboelectric energy harvesters realized by the formation of highly functional and controllable nanostructures via block copolymer (BCP) self-assembly. Our strategy is based on the incorporation of various silica nanostructures derived from the self-assembly of BCPs to enhance the characteristics of triboelectric nanogenerators (TENGs) by modulating the contact-surface area and the frictional force. Our simulation data also confirm that the nanoarchitectured morphologies are effective for triboelectric generation.
Computing Aggregates for Monitoring Wireless Sensor Networks (2003)

Wireless sensor networks involve very large numbers of small, low-power, wireless devices.Given their unattended nature, and their potential applications in harsh environments, we need a monitoring infrastructure that indicates system failures and resource depletion.In this paper, we briefly describe an architecture for sensor network monitoring, then focus on one aspect of this architecture: continuously computing aggregates (sum, average, count) of network properties (loss rates, energylevels etc., packet counts).Our contributions are two-fold.First, we propose a novel tree construction algorithm that enables energy-efficient computation of some classes of aggregates.Second, we show through actual implementation and experiments that wireless communication artifacts in even relatively benign environments can significantly impact the computation of these aggregate properties.In some cases, without careful attention to detail, the relative error in the computed aggregates can be as much as 50%.However, by carefully discarding links with heavy packet loss and asymmetry, we can improve accuracy by an order of magnitude.
