Ore genesis of the Cave-In-Rock Fluorspar District, Hardin County, Illinois (1962)

Continued prospecting and mining in the Cave-In-Rock fluorspar district has developed data that permits a more detailed study of ore genesis of the district. The stratigraphy of the ore-bearing horizons is described with emphasis on the chemical and physical characteristics of the formations. The contact relationship between the host formation and the blanketing formation is discussed in detail because of its apparent role in the movement of solutions. The structure is defined in 3 categories on the basis of inducing forces or elements. The mineralogy and paragenesis discussions stress the occurrence and the depositional characteristics of the minerals. These factors permit the statement of a new theory of origin of the textural features of the ores. Two breccia pipes are described and are designated as the points at which mineralizing solutions rose from a deep source. The distribution of ore about these breccia pipes indicates that the solutions moved by simple hydraulic principles and provide a basis for the study of solution movement.
Viewing direction-aware backlight scaling (2007)

High power consumption and limited viewing angles are the two major drawbacks of liquid crystal displays (LCDs). This paper models the angular-dependent luminance attenuation of a twisted nematic LCD and incorporates user's viewing direction into a backlight scaling framework such that the power consumption can be minimized while preserving the optimal image quality. We also studied the human factors of viewing direction variation, and developed an emulator for visualizing luminance attenuation and color shift in different viewing directions.
‘Redlands Summertaste’ Tomato (1985)

Abstract Bacterial wilt ( Pseudomonas solanacearum E.F. Smith biovar III) causes substantial losses in susceptible tomato ( Lycopersicon esculentum Mill.) cultivars in coastal Queensland from late spring to autumn (3). Verticillium wilt ( Verticillium dahliae Kleb. race 1) can be a major disease from autumn to early spring. A previously released cultivar, Scorpio (3), is resistant to bacterial wilt and Fusarium wilt ( Fusarium oxysporum Schlecht, ex Fr.f.sp. lycopersici (Sacc.) Snyd. and Hans, race 1), but lacks resistance to Verticillium wilt. Fruit of this cultivar are relatively soft. ‘Redlands Summertaste’ a hybrid, was developed to provide a locally adapted tomato cultivar in which resistances to bacterial, Verticillium and Fusarium wilts are combined with good fruit quality.
Molecular cloning, recombinant expression and IgE‐binding epitope of ω‐5 gliadin, a major allergen in wheat‐dependent exercise‐induced anaphylaxis (2005)

Wheat omega-5 gliadin has been identified as a major allergen in wheat-dependent exercise-induced anaphylaxis. We have detected seven IgE-binding epitopes in primary sequence of the protein. We newly identified four additional IgE-binding epitope sequences, QQFHQQQ, QSPEQQQ, YQQYPQQ and QQPPQQ, in three patients with wheat-dependent exercise-induced anaphylaxis in this study. Diagnosis and therapy of food allergy would benefit from the availability of defined recombinant allergens. However, because omega-5 gliadin gene has not been cloned, recombinant protein is currently unavailable. We sought to clone the omega-5 gliadin gene and produce the homogeneous recombinant protein for use in an in vitro diagnostic tool. Using a PCR-based strategy we isolated two full-length omega-5 gliadin genes, designated omega-5 and omega-5b, from wheat genomic DNA and determined the nucleotide sequences. The protein encoded by omega-5a was predicted to be 439 amino acids long with a calculated mass of 53 kDa; the omega-5b gene would encode a 393 amino acid, but it contains two stop codons indicating that omega-5b is pseudogene. The C-terminal half (178 amino acids) of the omega-5a gliadin protein, including all 11 IgE-binding epitope sequences, was expressed in Escherichia coli by means of the pET system and purified using RP-HPLC. Western blot analysis and dot blot inhibition assay of recombinant and native omega-5 gliadin purified from wheat flour demonstrated that recombinant protein had IgE-binding ability. Our results suggest that the recombinant protein can be a useful tool for identifying patients with wheat-dependent exercise-induced anaphylaxis in vitro.

On-line wear detection of milling tools using a displacement fiber optic sensor (2003)

A cost-effective technique for on-line wear monitoring of a milling tool is presented. The tool wear is estimated directly from a fiber optic sensor with high resolution and high bandwidth characteristics. This sensor provides a distance measurement between its probe and the tool profile. The contribution of this work is the application of this sensor to sense on-line wear of a milling tool. Since the light emitted by this sensor comes from a photodiode, it does not produce eye damage, this is safer than laser displacement sensors. This technique senses the tool wear in real time, while the tool is rotating, with an accuracy less than 1 micron. Experimental results are also presented for a four-flank cutting tool rotating at 300 rpm.
Demonstration of electronic dispersion compensation of single sideband optical transmission (2003)

We describe a demonstration of electrical chromatic dispersion compensation of 10 Gb/s single sideband optical signals. Eye-opening and bit error rates of less than 10 were achieved after compensation of -2040 ps/nm, equivalent to 120km of non-dispersion-shifted fibre and beyond the dispersion limit for 10Gb/s. A passive sideband filter was used to produce the single sideband signal, a technique that is applicable to low cost systems which use direct or electroabsorptive laser modulation. The wavelength tolerance of such systems was measured for the first time.
Measurement of percent carboxyhemoglobin with pulse-oximetry technique (1988)

Computer simulations based on the photon diffusion theory are carried out to analyze the feasibility of measuring the percent carboxyhemoglobin (%HbCO) using the pulse-oximetry technique. A series of in vitro experiments using a mechanical pulser to simulate the pumping effect of the heart is performed. Both the theoretical and the experimental data show that a pulse-oximetry technique using multiple wavelengths can be applied for the measurement of %HbCO.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">></ETX>
Diameter sizing of rolls in bridles that utilize powder clutches (1997)

The use of powder clutches for regulation of torque in entry and exit bridles of tension levelers must take into consideration the constraints imposed by the slip requirements of the powder clutch. This paper provides guidelines for roll diameter sizing as a function of the maximum linear line speed and worst case application tension profiles, such that the powder clutch always operates in a reasonable slip operating range.
Capacitive near-field communication for ubiquitous interaction and perception (2014)

Smart objects within instrumented environments offer an always available and intuitive way of interacting with a system. Connecting these objects to other objects in range or even to smartphones and computers, enables substantially innovative interaction and sensing approaches. In this paper, we investigate the concept of Capacitive Near-Field Communication to enable ubiquitous interaction with everyday objects in a short-range spatial context. Our central contribution is a generic framework describing and evaluating this communication method in Ubiquitous Computing. We prove the relevance of our approach by an open-source implementation of a low-cost object tag and a transceiver offering a high-quality communication link at typical distances up to 15 cm. Moreover, we present three case studies considering tangible interaction for the visually impaired, natural interaction with everyday objects, and sleeping behavior analysis.
Combined optic-flow and stereo-based navigation of urban canyons for a UAV (2005)

We present a novel vision-based technique for navigating an unmanned aerial vehicle (UAV) through urban canyons. Our technique relies on both optic flow and stereo vision information. We show that the combination of stereo and optic flow (stereo flow) is more effective at navigating urban canyons than either technique alone. Optic flow from a pair of sideways looking cameras is used to stay centered in a canyon and initiate turns at junctions, while stereo vision from a forward facing stereo head is used to avoid obstacles to the front. The technique was tested in full on an autonomous tractor at CSIRO and in part on the USC autonomous helicopter. Experimental results are presented from these two robotic platforms operating in outdoor environments. We show that the autonomous tractor can navigate urban canyons using stereo-flow, and that the autonomous helicopter can turn away from obstacles to the side using optic flow. In addition, preliminary results show that a single pair of forward facing fisheye cameras can be used for both stereo and optic flow. The center portions of the fisheye images are used for stereo, while flow is measured in the periphery of the images.

Which Impact for β-Damascenone on Red Wines Aroma? (2007)

beta-Damascenone, a C-13 norisoprenoid compound, is usually presented as an impact odorant in red wines. Its direct contribution to their aroma was investigated. Both free beta-damascenone and beta-damascenone precursors were isolated from various French red wines and then analyzed by gas chromatography-mass spectrometry, revealing concentrations in the vicinity of 1 and 2 microg/L for free compounds and both forms, respectively. Gas chromatography-olfactometry analyses were also performed on dilutions of both red wine extracts and pure beta-damascenone. The very low detection threshold in olfactometry for this compound explains why it is found at the highest dilution factor in aroma extract dilution analysis methods. Moreover, determination of beta-damascenone's odor thresholds confirmed the huge importance of the matrix: beta-Damascenone is characterized by a very low perception threshold in hydroalcoholic solution as compared to red wine, where it is over 1000-fold higher. In hydroalcoholic solution, beta-damascenone enhanced fruity notes of ethyl cinnamate and caproate and masked the herbaceous aroma of IBMP. Globally, these results suggested that beta-damascenone has more an indirect than a direct impact on red wine aroma.
The upgraded Pegasus Toroidal Experiment (2006)

The Pegasus Toroidal Experiment was developed to explore the physics limits of plasma operation as the aspect ratio (A) approaches unity. Initial experiments on the device found that access to high normalized current and toroidal beta was limited by the presence of large-scale tearing modes. Major upgrades have been conducted of the facility to provide the control tools necessary to mitigate these resistive modes. The upgrades include new programmable power supplies, new poloidal field coils and increased, time-variable toroidal field. First ohmic operations with the upgraded system demonstrated position and current ramp-rate control, as well as improvement in ohmic flux consumption from 2.9 MA Wb−1 to 4.2 MA Wb−1. The upgraded experiment will be used to address three areas of physics interest. First, the kink and ballooning stability boundaries at low A and high normalized current will be investigated. Second, clean, high-current plasma sources will be studied as a helicity injection tool. Experiments with two such sources have produced toroidal currents three times greater than predicted by geometric field line following. Finally, the use of electron Bernstein waves to heat and drive current locally will be studied at the 1 MW level; initial modelling indicates that these experiments are feasible at a frequency of 2.45 GHz.
A distributed monitoring mechanism for wireless sensor networks (2002)

In this paper we focus on a large class of wireless sensor networks that are designed and used for monitoring and surveillance. The single most important mechanism underlying such systems is the monitoring of the network itself, that is, the control center needs to be constantly made aware of the existence/health of all the sensors in the network for security reasons. In this study we present plausible alternative communication strategies that can achieve this goal, and then develop and study in more detail a distributed monitoring mechanism that aims at localized decision making and minimizing the propagation of false alarms. Key constraints of such systems include low energy consumption and low complexity. Key performance measures of this mechanism include high detection accuracy (low false alarm probabilities) and high responsiveness (low response latency). We investigate the trade-offs via simulation.
Cyclic Tetrapyrrole Sulfonation, Metals, and Oligomerization in Antiprion Activity (2007)

Cyclic tetrapyrroles are among the most potent compounds with activity against transmissible spongiform encephalopathies (TSEs; or prion diseases). Here the effects of differential sulfonation and metal binding to cyclic tetrapyrroles were investigated. Their potencies in inhibiting disease-associated protease-resistant prion protein were compared in several types of TSE-infected cell cultures. In addition, prophylactic antiscrapie activities were determined in scrapie-infected mice. The activity of phthalocyanine was relatively insensitive to the number of peripheral sulfonate groups but varied with the type of metal bound at the center of the molecule. The tendency of the various phthalocyanine sulfonates to oligomerize (i.e., stack) correlated with anti-TSE activity. Notably, aluminum(III) phthalocyanine tetrasulfonate was both the poorest anti-TSE compound and the least prone to oligomerization in aqueous media. Similar comparisons of iron- and manganese-bound porphyrin sulfonates confirmed that stacking ability correlates with anti-TSE activity among cyclic tetrapyrroles.
Triangulation and Embedding Using Small Sets of Beacons (2004)

Concurrent with recent theoretical interest in the problem of metric embedding, a growing body of research in the networking community has studied the distance matrix defined by node-to-node latencies in the Internet, resulting in a number of recent approaches that approximately embed this distance matrix into low-dimensional Euclidean space. Here we give algorithms with provable performance guarantees for beacon-based triangulation and embedding. We show that in addition to multiplicative error in the distances, performance guarantees for beacon-based algorithms typically must include a notion of slack - a certain fraction of all distances may be arbitrarily distorted. For metrics of bounded doubling dimension (which have been proposed as a reasonable abstraction of Internet latencies), we show that triangulation-based reconstruction with a constant number of beacons can achieve multiplicative error 1 + /spl delta/ on a 1 - /spl epsiv/ fraction of distances, for arbitrarily small constants /spl delta/ and /spl epsiv/. For this same class of metrics, we give a beacon-based embedding algorithm that achieves constant distortion on a 1 - /spl epsiv/ fraction of distances; this provides some theoretical justification for the success of the recent global network positioning algorithm of Ng and Zhang, and it forms an interesting contrast with lower bounds showing that it is not possible to embed all distances in a doubling metric with constant distortion. We also give results for other classes of metrics, as well as distributed algorithms that require only a sparse set of distances but do not place too much measurement load on any one node.
5-Deazaflavin derivatives as inhibitors of p53 ubiquitination by HDM2 (2013)

Based on previous reports of certain 5-deazaflavin derivatives being capable of activating the tumour suppressor p53 in cancer cells through inhibition of the p53-specific ubiquitin E3 ligase HDM2, we have conducted an structure-activity relationship (SAR) analysis through systematic modification of the 5-deazaflavin template. This analysis shows that HDM2-inhibitory activity depends on a combination of factors. The most active compounds (e.g., 15) contain a trifluoromethyl or chloro substituent at the deazaflavin C9 position and this activity depends to a large extent on the presence of at least one additional halogen or methyl substituent of the phenyl group at N10. Our SAR results, in combination with the HDM2 RING domain receptor recognition model we present, form the basis for the design of drug-like and potent activators of p53 for potential cancer therapy.
A simplified analog controller for power factor correction converters (1995)

To improve power factor and to meet IEC 555-2 harmonic requirements, input power factor correction circuits have been used, widely, in the power supply industry. In response to the trend, this study proposes and investigates a simple controller for a single-phase AC to DC rectifier with input power factor correction.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">></ETX>
Regulation of MAP kinase by calcium-sensing receptor in bovine parathyroid and CaR-transfected HEK293 cells (2001)

Regulation of the extracellular signal-regulated kinase 1 and 2 (ERK1/2) pathway by the extracellular calcium (Ca o 2+ )-sensing receptor (CaR) was investigated in bovine parathyroid and CaR-transfected human embryonic kidney (HEKCaR) cells. Elevating Ca o 2+ or adding the selective CaR activator NPS R-467 elicited rapid, dose-dependent phosphorylation of ERK1/2. These phosphorylations were attenuated by pretreatment with pertussis toxin (PTX) or by treatment with the phosphotyrosine kinase (PTK) inhibitors genistein and herbimycin, the phosphatidylinositol-specific phospholipase C (PI-PLC) inhibitor U-73122, or the protein kinase C (PKC) inhibitor GF109203X and were enhanced by the PKC activator phorbol 12-myristate 13-acetate. Combined treatment with PTX and inhibitors of both PKC and PTK nearly abolished high Ca o 2+ -evoked ERK1/2 activation in HEKCaR cells, demonstrating CaR-mediated coupling via both G q and G i . High Ca o 2+ increased serine phosphorylation of the 85-kDa cytosolic phospholipase A 2 (cPLA 2 ) in both parathyroid and HEKCaR cells. The selective mitogen-activated protein kinase (MAPK) inhibitor PD98059 abolished high-Ca o 2+ -induced ERK1/2 activation and reduced cPLA 2 phosphorylation in both cell types, documenting MAPK's role in cPLA 2 activation. Thus our data suggest that the CaR activates MAPK through PKC, presumably through G q/11 -mediated activation of PI-PLC, as well as through G i - and PTK-dependent pathway(s) in bovine parathyroid and HEKCaR cells and indicate the importance of MAPK in cPLA 2 activation.
Thermal effects in quantum dot lasers (1999)

The thermal behavior of lasers based on In0.5Ga0.5/As/GaAs self-aggregated quantum dots is investigated. Increasing temperature from 10 to 290 K produces a narrowing of the dot laser mode distribution. This effect is explained in terms of carrier relaxation between dots and carrier thermal escape from dots to nonradiative recombination centers. The thermal dependence of the threshold current and the differential quantum efficiency is also discussed.
Automatic recognition of alertness and drowsiness from EEG by an artificial neural network (2002)

We present a novel method for classifying alert vs drowsy states from 1 s long sequences of full spectrum EEG recordings in an arbitrary subject. This novel method uses time series of interhemispheric and intrahemispheric cross spectral densities of full spectrum EEG as the input to an artificial neural network (ANN) with two discrete outputs: drowsy and alert. The experimental data were collected from 17 subjects. Two experts in EEG interpretation visually inspected the data and provided the necessary expertise for the training of an ANN. We selected the following three ANNs as potential candidates: (1) the linear network with Widrow-Hoff (WH) algorithm; (2) the non-linear ANN with the Levenberg-Marquardt (LM) rule; and (3) the Learning Vector Quantization (LVQ) neural network. We showed that the LVQ neural network gives the best classification compared with the linear network that uses WH algorithm (the worst), and the non-linear network trained with the LM rule. Classification properties of LVQ were validated using the data recorded in 12 healthy volunteer subjects, yet whose EEG recordings have not been used for the training of the ANN. The statistics were used as a measure of potential applicability of the LVQ: the t-distribution showed that matching between the human assessment and the network output was 94.37+/-1.95%. This result suggests that the automatic recognition algorithm is applicable for distinguishing between alert and drowsy state in recordings that have not been used for the training.
