Automated hull reconstruction motion tracking (HRMT) applied to sideways maneuvers of free-flying insects (2009)

Flying insects perform aerial maneuvers through slight manipulations of their wing motions. Because such manipulations in wing kinematics are subtle, a reliable method is needed to properly discern consistent kinematic strategies used by the insect from inconsistent variations and measurement error. Here, we introduce a novel automated method that accurately extracts full, 3D body and wing kinematics from high-resolution films of free-flying insects. This method combines visual hull reconstruction, principal components analysis, and geometric information about the insect to recover time series data of positions and orientations. The technique has small, well-characterized errors of under 3 pixels for positions and 5 deg. for orientations. To show its utility, we apply this motion tracking to the flight of fruit flies, Drosophila melanogaster. We find that fruit flies generate sideways forces during some maneuvers and that strong lateral acceleration is associated with differences between the left and right wing angles of attack. Remarkably, this asymmetry can be induced by simply altering the relative timing of flips between the right and left wings, and we observe that fruit flies employ timing differences as high as 10% of a wing beat period while accelerating sideways at 40% g.
Short- and Long Term Treatment with Indometacin Causes Renal Phospholipid Alteration: A Possible Explanation for Indometacin Nephrotoxicity (1994)

Phospholipid content was studied in kidneys from rats treated with indometacin. Short-term treatment was performed by using low (1 and 5 mg/kg/day) and high (10 and 50 mg/kg/day) doses of indometacin. Long-term treatment was achieved by using only low doses of indometacin. Short-term treatment at low doses did not result in any change in the phospholipid content. In rats administered higher concentrations, indometacin caused a marked increase in all papillary phospholipid contents, but no effect was observed in the medulla, and an increase in sphingomyelin and phosphatidylethanolamine was observed in the cortex. Long-term treatment with administration of 1 mg/kg/day of indometacin led to an increase in all papillary phospholipids from the 2nd week of treatment. Medullary phospholipids also increased, but no changes were observed in cortical phospholipids. These results show that indometacin causes phospholipid accumulation in rat kidney and that the papilla is the most sensitive renal tissue.
A Systematic Survey of the Factors Affecting Zircaloy Nodular Corrosion (1989)

Out-of-reactor corrosion tests in 10.3-MPa steam at temperatures between 490 and 530°C have been carried out on Zircaloy-2 tube specimens of various fabrication histories including archive specimens of the same tube lots as were used in the commercial boiling water reactor (BWR) to get data for comparison between in- and out-of-reactor nodular corrosion performances. Test conditions, such as temperature and duration, as well as material parameters, such as chemical composition, texture, and precipitates, were examined to clarify the relation to the nodular corrosion susceptibility. The number density and size of nodules increased when tested at higher temperatures. Extending the test duration increased the nodule size, but not the number density. The archive tube lots showed different degrees of nodular corrosion in the out-of-reactor test and their relative rankings seemed to correlate with the visual ratings of in-reactor corrosion. A higher number density of precipitates tended to reduce the nodular corrosion susceptibility. It should be noted, however, that some lots constituted an exception to this, and the cause was sought in the tube manufacturing processes.
Responsiveness to Retinoic Acid Changes during Chondrocyte Maturation (1993)

We previously showed that retinoic acid (RA) participates in the regulation of chondrocyte maturation during endochondral ossification, a process involving multiple developmental stages. To assess whether the responsiveness to RA treatment changes during chondrocyte maturation, immature chondrocytes were isolated from the caudal portion of Day 18-19 chick embryo sterna, a portion that remains cartilaginous through early postnatal life but ossifies with age. The immature cells were allowed to reach different stages of maturation by growth for different time in culture. Progression by the cells toward the mature phenotype during culture was confirmed by increases in average cell diameter, proteoglycan synthesis, and alkaline phosphatase (APase) activity. When developmentally immature passage 0 (PO) cultures were treated with RA (10-100 nM) for 72 h, the cells readily became fibroblastic, reduced drastically their proteoglycan synthesis, and failed to activate type X collagen gene expression. When older cultures (P1 and P2) were treated with RA, the cells acquired a characteristic epithelioid shape and increased their APase activity. Moreover, 5-10% of P1 cells and 20-25% of P2 cells activated type X collagen synthesis in response to RA. RA treatment markedly induced expression of the gene encoding the beta isoform of retinoic acid receptor (RAR beta) and also provoked a moderate 2.5-fold increase in RAR alpha gene expression. A similar change in responsiveness to RA was observed during maturation in vivo. Chondrocytes were isolated from the cephalic portion of Day 10, 11, 13, and 16 chick embryo sterna, and were treated with different doses of RA (10-100 nM) for 72 h. The cells from the Day 10 sternum failed to activate type X collagen gene expression in response to RA. In contrast, with increasing age of the embryos, an increasing fraction of cells induced type X collagen gene expression in response to RA. We conclude that responsiveness to RA changes during the early stages of chondrocyte maturation and that maturation depends on interactions between exogenous retinoids and the endogenous developmental program of chondrocytes.
Evaluation of a Novel Medication Aid, the Calendar Blister‐Pak, and its Effect on Drug Compliance in a Geriatric Outpatient Clinic (1987)

A prospective, controlled, crossover study on drug compliance was initiated in 22 elderly patients from a geriatric clinic. Half of the patients received their pills from a commercially prepared calendar mealtime blister-pak; the remaining patients received their medication from standard pill bottles. At the end of three months the two groups were crossed over. Pill count and issuance of a new drug supply were done monthly to assess compliance. It was found that the average noncompliance index was significantly decreased (9.17 to 2.04) with the blister-pak packaging system. The relationship of age, Folstein mini-mental status, overcompliance, frequency of dosing interval, and living situation were also explored.
Properties of Vapour Phase Grown Mercuric Iodide Single Crystal Detectors (1975)

The growth of red mercuric iodide single crystals by a dynamic sublimation method is described. Their characterization has been performed by means of optical and electrical measurements. Nuclear radiation detectors have been prepared with this material and their properties are evaluated in terms of a particles, γ- and X-rays spectrometry, detection efficiency, electron-hole pair creation energy and polarization effects. Finally the potential use of mercuric iodide in nuclear detection is discussed.
Changes in Intraocular Pressure After Laser in situ Keratomileusis (2001)

LASIK for myopia produced underestimation of IOP measured by Goldmann applanation tonometry at the central part of the cornea by a mean of 3.69 +/- 1.63 mmHg. The decrease of IOP was related to preoperative IOP and the change in central corneal thickness after LASIK. Temporal Goldmann applanation tonometry measurements, although decreased after LASIK, were less reliable.
Identification of lipopolysaccharide-binding proteins in 70Z/3 cells by photoaffinity cross-linking. (1990)

A radioiodinated, photoactivatable derivative of Salmonella minnesota Re595 lipopolysaccharide (LPS) was used to label LPS-binding proteins in 70Z/3 cells. The labeled proteins were resolved by sodium dodecyl sulfate-polyacrylamide gel electrophoresis and visualized by autoradiography. 125I-Labeled-2-(p-azidosalycylamido)1,3'-dithiopropionamide S. minnesota Re595 LPS (125I-ASD-Re595) labeled a limited number of proteins. The most prominent of these had a apparent molecular mass of 18 kDa. Less prominent labeling of 25- and 28-kDa proteins was also seen. Labeling was saturated by 5 micrograms/ml 125I-ASD-Re595 and was inhibited by a 10-100-fold excess of unlabeled LPS or lipid A. Labeling was maximal within 30 min at 37 degrees C; much less labeling occurred at lower temperatures. The proteins labeled with 125I-ASD-Re595 appear to be on the surface of the cell, since they can be digested by trypsin and were found in the membrane fraction of the cell but not in the cytosol. Studies with competitive inhibitors suggested that the proteins bind to the lipid A region of the LPS molecule. Biologically inactive lipid A analogs were poor inhibitors of labeling, suggesting that the LPS-binding proteins could discriminate between active lipid A and inactive analogs. These studies suggest that the 18- and 25-kDa proteins bind specifically to the lipid A region of the LPS molecule and should be considered as candidates for a functional LPS receptor.
Aging and qualification research on solenoid operated valves (1988)

A research program was conducted on the aging and qualification of solenoid operated valves (SOVs) used in nuclear power generating stations. Tests were conducted on three-way, direct acting SOVs, manufactured by Automatic Switch Co. (ASCO) and Valcor Engineering Corp. Some SOVs had been aged naturally through service in nuclear power plants and others were subjected to accelerated aging. Thermal aging was conducted both with air and nitrogen as the process gas. Operational aging was simulated by putting the specimens through operational cycles at intervals during the accelerated thermal aging, with the environmental temperature controlled at a level representative of service conditions. The program also included simulation of a design basis event (DBE), that consisted of DBE gamma irradiation and a 30-d main steam line break/loss of coolant accident (MSLB/LOCA) simulation. After each major segment of the test program (aging, irradiation, and MSLB/LOCA simulation), some of the valve specimens were subjected to operational testing, then disassembled for inspection of all parts and measurement of physical properties (Shore A durometer hardness, elongation at break, and relaxation after compression) of the elastomeric parts.
An Automatic Slope-Calibrated Ramp Generator for Single-Slope ADCs (2019)

This paper presents a ramp generator with automatic slope calibration which is able to compensate slope deviation due to process and environmental effects. A novel analog feedback circuit is proposed to regulate the stop voltage in successive approximation while fix the start voltage of the ramp automatically without much calibration code input or complicated auxiliary circuits, which reduces the complexity of circuitry and timing, meanwhile, saves area and power. A 12-bit single-slope ADC (SS-ADC), employing the proposed ramp generator, has been implemented in a 0.11-µm CMOS process. The simulation results show that the offset of the ramp's stop voltage is reduced to 0.1 LSB and the nonlinearity of the ramp is 0.034%. Besides, the measurement results verify that this structure can fulfill automatic slope calibration.
Scheduling heuristics for data requests in an oversubscribed network with priorities and deadlines (2002)

Providing up-to-date input to users' applications is an important data management problem for a distributed computing environment, where each data storage location and intermediate node may have specific data available, storage limitations, and communication links available. Sites in the network request data items and each request has an associated deadline and priority. This work concentrates on solving a basic version of the data staging problem in which all parameter values for the communication system and the data request information represent the best known information collected so far and stay fixed throughout the scheduling process. The network is assumed to be oversubscribed and not all requests for data items can be satisfied. A mathematical model for the basic data staging problem is given. Then, three multiple-source shortest-path algorithm based heuristics for finding a near-optimal schedule of the communication steps for staging the data are presented. Each heuristic can be used with each of four cost criteria developed. Thus, twelve implementations are examined. In addition, two different weightings for the relative importance of different priority levels are considered. The performance of the proposed heuristics is evaluated and compared by simulations. The proposed heuristics are shown to perform well with respect to upper and lower bounds. Furthermore, the heuristics and a complex cost criterion allow more highest priority messages to be received than a simple-cost-based heuristic that schedules all highest priority messages first.
Uncertainties in Parameters Estimated with Neural Networks: Application to Strong Gravitational Lensing (2017)

Abstract In Hezaveh et al. we showed that deep learning can be used for model parameter estimation and trained convolutional neural networks to determine the parameters of strong gravitational-lensing systems. Here we demonstrate a method for obtaining the uncertainties of these parameters. We review the framework of variational inference to obtain approximate posteriors of Bayesian neural networks and apply it to a network trained to estimate the parameters of the Singular Isothermal Ellipsoid plus external shear and total flux magnification. We show that the method can capture the uncertainties due to different levels of noise in the input data, as well as training and architecture-related errors made by the network. To evaluate the accuracy of the resulting uncertainties, we calculate the coverage probabilities of marginalized distributions for each lensing parameter. By tuning a single variational parameter, the dropout rate, we obtain coverage probabilities approximately equal to the confidence levels for which they were calculated, resulting in accurate and precise uncertainty estimates. Our results suggest that the application of approximate Bayesian neural networks to astrophysical modeling problems can be a fast alternative to Monte Carlo Markov Chains, allowing orders of magnitude improvement in speed.

Signal detection performance in indoor environments with a synthetic antenna array (2009)

This paper analysis the performances of a single antenna handheld receiver in detecting a signal in a Rayleigh multipath fading environment. If the antenna is spatially fixed during the time interval that the signal is sampled then signal coherency is maintained. However, the signal will be subject to statistically large fading losses. The alternative is to spatially translate the antenna along some arbitrary random trajectory during the snapshot interval. It will be shown that a significant net processing gain resulting from randomly moving the antenna relative to keeping it stationary is achievable. It is further demonstrated that for a given utilization scenario, there is an optimum trajectory size which maximizes the processing gain advantage of the moving antenna. An extensive set of measurements based on CDMA - 2000 pilot signals propagated from outdoor terrestrial base stations, captured in indoor multipath environments using stationary and moving antennas are used to experimentally verify these theoretical findings.
Zero-VAE-GAN: Generating Unseen Features for Generalized and Transductive Zero-Shot Learning (2020)

Zero-shot learning (ZSL) is a challenging task due to the lack of unseen class data during training. Existing works attempt to establish a mapping between the visual and class spaces through a common intermediate semantic space. The main limitation of existing methods is the strong bias towards seen class, known as the domain shift problem, which leads to unsatisfactory performance in both conventional and generalized ZSL tasks. To tackle this challenge, we propose to convert ZSL to the conventional supervised learning by generating features for unseen classes. To this end, a joint generative model that couples variational autoencoder (VAE) and generative adversarial network (GAN), called Zero-VAE-GAN, is proposed to generate high-quality unseen features. To enhance the class-level discriminability, an adversarial categorization network is incorporated into the joint framework. Besides, we propose two self-training strategies to augment unlabeled unseen features for the transductive extension of our model, addressing the domain shift problem to a large extent. Experimental results on five standard benchmarks and a large-scale dataset demonstrate the superiority of our generative model over the state-of-the-art methods for conventional, especially generalized ZSL tasks. Moreover, the further improvement of the transductive setting demonstrates the effectiveness of the proposed self-training strategies.
Inhibition of nNOS expression in the macula densa by COX-2-derived prostaglandin E<sub>2</sub> (2004)

It is well established that cyclooxygenase-2 (COX-2) and the neuronal form of nitric oxide synthase (nNOS) are coexpressed in macula densa cells and that the expression of both enzymes is stimulated in a number of high-renin states. To further explore the role of nNOS and COX-2 in renin secretion, we determined plasma renin activity in mice deficient in nNOS or COX-2. Plasma renin activity was significantly reduced in nNOS -/- mice on a mixed genetic background and in COX-2 -/- mice on either BALB/c or C57/BL6 congenic backgrounds. In additional studies, we accumulated evidence to show an inhibitory influence of PGE(2) on nNOS expression. In a cultured macula densa cell line, PGE(2) significantly reduced nNOS mRNA expression, as quantified by real-time RT-PCR. In COX-2 -/- mice, nNOS mRNA expression in the kidney, determined by real-time RT-PCR, was upregulated throughout the postnatal periods, ranging from postnatal day (PND) 3 to PND 60. The induction of nNOS protein expression and NOS activity in COX-2 -/- mice was localized to macula densa cells using immunohistochemistry and NADPH-diaphorase staining methods, respectively. Therefore, these findings reveal that the absence of either COX-2 or nNOS is associated with suppressed renin secretion. Furthermore, the inhibitory effect of PGE(2) on nNOS mRNA expression indicates a novel interaction between NO and prostaglandin-mediated pathways of renin regulation.
The glucose transporter of Escherichia coli. Overexpression, purification, and characterization of functional domains. (1994)

The glucose transporter of the bacterial phosphotransferase system couples vectorial translocation to phosphorylation of the transported sugar. It consists of a transmembrane subunit (IICBGlc) and a hydrophilic subunit (IIAGlc). The IICBGlc subunit consists of two domains. The NH2-terminal IIC domain (residues 1-386) spans the membrane eight times and contains the substrate binding site. The COOH-terminal hydrophilic IIB domain (residues 391-476) is accessible from the cytoplasmic side of the membrane. It contains the phosphorylation site (Cys421) and together with the IIC domain catalyzes the transfer of phosphoryl groups from the IIAGlc subunit to the transported solute. Starting from a plasmid vector containing ptsG under an inducible promoter, the IIB and the IIC domains have been subcloned separately, overexpressed in Escherichia coli, and purified by Ni2+ chelate affinity chromatography. Approximately 40 mg of IIBGlc-6H and 4 mg of IICGlc-6H could be purified from 1 liter of culture. Cells expressing IIBGlc-6H and IICGlc-6H separately have a three times longer generation time on glucose minimal medium than cells expressing wild-type IICBGlc. The rate of IIBGlc-6H phosphorylation determined in a nitrocellulose filter binding assay is indistinguishable from wild-type IICBGlc. The in vitro specific activity of IICGlc-6H in the presence of excess IIBGlc-6H is 2% of the control. IIBGlc-6H also complements the activity of a IICBGlc mutant with an inactive IIB domain (C421S) indicating that IIC and IIB are flexibly linked such that a free IIB domain can displace an inactive IIB domain from its contact site on the IIC domain. Based on this work, the secondary structure of the IIBGlc domain has been determined by isotope-edited NMR spectroscopy (Golic Grdadolnik, S., Eberstadt, M., Gemmecker, G., Kessler, H., Buhr, A., and Erni, B. (1994) Eur. J. Biochem. 219, 945-952).
Self-organized spiral columns in laterally grafted rods (2010)

Attachment of a flexible coil on the mid-part of a rigid rod block generates T-shaped rod-coil block molecules that self-assemble into a stepped column. These layers, in turn, self-curve into a spiral column with tunable core structure in the solid state.
Acquired von Willebrand's disease in the myeloproliferative syndrome (1984)

An acquired hemorrhagic disorder developed in two patients in association with postsplenectomy thrombocytosis and leukocytosis during the course of the myeloproliferative syndrome. The presence of acquired von Willebrand's disease in these individuals was demonstrated by a decrease or absence of the larger von Willebrand factor (vWF) multimers, alteration of the repeating vWF multimeric "triplet," decreased ristocetin cofactor activity (vWF:RCo), and prolonged bleeding time. The bleeding stopped in both patients after treatment with either 1-deamino-[8-D-arginine]-vasopressin (DDAVP) or Cohn fraction I. Treatment with thrombocytapheresis and azathioprine or busulfan resulted in reduction of the elevated platelet and white cell counts and was associated with partial correction of the vWF abnormalities and remission of the hemostatic abnormalities. In five additional patients with the myeloproliferative syndrome, but without bleeding symptoms, large multimers of plasma vWF were diminished also. These findings suggest that acquired von Willebrand's disease should be considered when a bleeding diathesis develops during the course of the myeloproliferative syndrome.
Secure MPC for Analytics as a Web Application (2016)

Companies, government agencies, and other organizations have been analyzing data pertaining to their internal operations with great effect, such as in evaluating performance or improving efficiency. While each organization's own data is valuable internally, aggregate data from multiple organizations can have value to the organizations themselves, policymakers, and society. Unfortunately, an organization's data is often proprietary and confidential, and its release may be potentially deleterious to the organization's interests. Secure multi-party computation (MPC) resolves this tension: aggregate data may be computed while protecting each contributor's confidentiality. Theoretical constructs have been known for decades [1]-[3] and recent efforts aim to deliver them to end-users [4]-[6].
