Keynote address (summary only). (1986)

Alan Kay asked us to remember the words of Bob Barton, “good ideas don't often scale”, with respect to using the same window paradigm for everything from Macintoshes to ultra-high resolution large screens. He further suggested that good user interfaces should be useable by children under six years of age. Adults don't make good subjects because they have too much patience. “They've learned to suffer. That's what schools are for”. A videotape of a 22 month-old girl adroitly using MacPaint drove home his point. Kay promoted the idea of “agents”, computer-created creatures with personality and some ability to act on their own. As an experiment in using advanced technology to further this idea, Kay brought together a group of people including a Disney animator to spend a weekend with an E&S CT-6 real-time shaded graphics system. Out of this came some very interesting animation of a bouncing rabbit's-eye-view ramble through an infinite forest and a swim in a shallow sea in the company of a couple of realistically swimming sharks. We were exhorted to strive for impressionistic imagery such as that seen in the dance of the Sugar-Plum fairies in Disney's Fantasia, rather than spending teraflops trying to achieve the ever-receding goal of absolute realism. Kay closed by noting that while art imitates life, computer art/animation can imitate creation itself.
A correlation for the second interaction virial coefficients and enhancement factors for moist air (1975)

Experimental measurements of the enhancement factors for mixtures of water vapor and CO<sub>2</sub>-free air have been made at -20, -10, and +70 °C. The results, coupled with previous experimental enhancement data, have been used to calculate the second interaction virial coefficients, <i>B</i> <sub><i>aw</i></sub> , for water vapor air mixtures from -50 to +90 °C. Within this temperature range, an error analysis shows that the uncertainties in <i>B</i> <sub><i>aw</i></sub> are between 6 and 10 percent. The calculated <i>B</i> <sub><i>aw</i></sub> <i>·</i> values are used in deriving enhancement factors at 10 °C intervals for -50<<i>t</i><90 °C, at varying pressure intervals from 0.25 to 100 bar. The associated uncertainties are shown as a function of pressure and temperature. The enhancement factors are extrapolated to -80 °C.
Cooperative effects in the oxidation of CO by palladium oxide cations (2011)

Cooperative reactivity plays an important role in the oxidation of CO to CO(2) by palladium oxide cations and offers insight into factors which influence catalysis. Comprehensive studies including guided-ion-beam mass spectrometry and theoretical investigations reveal the reaction products and profiles of PdO(2)(+) and PdO(3)(+) with CO through oxygen radical centers and dioxygen complexes bound to the Pd atom. O radical centers are more reactive than the dioxygen complexes, and experimental evidence of both direct and cooperative CO oxidation with the adsorption of two CO molecules are observed. The binding of multiple electron withdrawing CO molecules is found to increase the barrier heights for reactivity due to decreased binding of the secondary CO molecule, however, reactivity is enhanced by the increase in kinetic energy available to hurdle the barrier. We examine the effect of oxygen sites, cooperative ligands, and spin including two-state reactivity.
Induction of radical scavenging ability and protection against radiation-induced damage to microsomal membranes following low-dose irradiation (1999)

Low doses of radiation increased cytosolic radical scavenging ability and resulted in protection of microsomal membrane function which is easily damaged by radiation-induced free radicals.

Frequency domain latency and relaxation-based harmonic analysis of nonlinear circuits (2002)

The authors describe a relaxation-based algorithm for the harmonic analysis of nonlinear circuits. They present iterated spectrum analysis based on the harmonic balance method, where this method is applied to every node independently. As a result, one can avoid dealing with large-scale Jacobian matrices and reduce the total simulation time, compared with the previous method based on the standard Newton-Raphson method. An algorithm with two types of latency, iteration latency and frequency-domain latency, is considered. A multirate-sampling technique based on consideration of the frequency-domain latency is proposed. The authors apply the present algorithm to a simple analog circuit simulation and verify its availability for harmonic analysis.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">></ETX>
Comparative Genomics of Wolbachia and the Bacterial Species Concept (2013)

The importance of host-specialization to speciation processes in obligate host-associated bacteria is well known, as is also the ability of recombination to generate cohesion in bacterial populations. However, whether divergent strains of highly recombining intracellular bacteria, such as Wolbachia, can maintain their genetic distinctness when infecting the same host is not known. We first developed a protocol for the genome sequencing of uncultivable endosymbionts. Using this method, we have sequenced the complete genomes of the Wolbachia strains wHa and wNo, which occur as natural double infections in Drosophila simulans populations on the Seychelles and in New Caledonia. Taxonomically, wHa belong to supergroup A and wNo to supergroup B. A comparative genomics study including additional strains supported the supergroup classification scheme and revealed 24 and 33 group-specific genes, putatively involved in host-adaptation processes. Recombination frequencies were high for strains of the same supergroup despite different host-preference patterns, leading to genomic cohesion. The inferred recombination fragments for strains of different supergroups were of short sizes, and the genomes of the co-infecting Wolbachia strains wHa and wNo were not more similar to each other and did not share more genes than other A- and B-group strains that infect different hosts. We conclude that Wolbachia strains of supergroup A and B represent genetically distinct clades, and that strains of different supergroups can co-exist in the same arthropod host without converging into the same species. This suggests that the supergroups are irreversibly separated and that barriers other than host-specialization are able to maintain distinct clades in recombining endosymbiont populations. Acquiring a good knowledge of the barriers to genetic exchange in Wolbachia will advance our understanding of how endosymbiont communities are constructed from vertically and horizontally transmitted genes.
Dihydrotestosterone affects the growth of hormone-unresponsive breast cancer cells: an indirect action. (1996)

Cell to cell interaction, which plays a crucial role in breast cancer growth, may be regulated by steroid hormones. This study examined dihydrotestosterone (DHT) effects on the interaction between the steroid receptor positive MCF-7 and the steroid receptor negative MDA-MB-231 breast cancer cell lines. The growth of MDA-MB-231 cells was inhibited by medium conditioned by MCF-7 cells grown in presence of DHT but not by medium conditioned by MCF-7 cells grown in presence of both DHT and the antiandrogen hydroxyflutamide. Trypsin pretreatment of conditioned medium abolished its growth-inhibitory effect on hormone-unresponsive cells. DHT itself did not affect the growth of MDA-MB-231 cells when directly added to their culture medium. Data suggest that DHT stimulates, via the androgen receptor, the androgen-responsive breast cancer cells to produce a peptide factor(s) capable of inhibiting the growth of hormone-unresponsive cells.
Solid state photomultiplier: noise parameters of photodetectors with internal discrete amplification (2006)

We have designed and developed a new family of photodetectors with Internal Discrete Amplification (IDA) mechanism They operate as solid state photomultiplier devices at room temperature and may be used in numerous applications where high bandwidth of the detector is necessary in combination with maximum sensitivity and low excess noise. The photodetectors can operate in linear detection mode with gain-bandwidth product up to 5 times 10<sup>14</sup> as well as in photon counting mode with count rates up to 10<sup>8</sup> counts/sec. The key performance characteristics exceed those of Photomultiplier Tube (PMT) and Avalanche Photodiode (APD) devices. The detectors have gain > 10<sup>5</sup>, excess noise factor as low as 1.03, photoresponse rise/fall time < 300 ps, and timing resolution (jitter) < 200 ps. The combination of low excess noise at high gain and wide bandwidth, as well as scalability to large active areas, presents the main advantages of this technology over conventional photodetector solutions. Ultra low excess noise is one of the main features of the internal Discrete Amplification Detector (DAD), and in this paper its nature has been investigated more comprehensively. We investigated the behavior of the noise-factor and afterpulsing, and conclude that both have the same physical nature. Optical cross-talk between channels is shown to be responsible for the afterpulsing phenomenon, and, in turn, is the main source of excess noise. Thus, the noise characteristics of an DAD device and its timing resolution may be significantly improved as they are limited not by the discrete amplifier channel properties itself, but by the cross-talk, which strongly depends on the device design.

Learning to Solve SMT Formulas (2018)

We present a new approach for learning to solve SMT formulas. We phrase the challenge of solving SMT formulas as a tree search problem where at each step a transformation is applied to the input formula until the formula is solved. Our approach works in two phases: first, given a dataset of unsolved formulas we learn a policy that for each formula selects a suitable transformation to apply at each step in order to solve the formula, and second, we synthesize a strategy in the form of a loop-free program with branches. This strategy is an interpretable representation of the policy decisions and is used to guide the SMT solver to decide formulas more efficiently, without requiring any modification to the solver itself and without needing to evaluate the learned policy at inference time. We show that our approach is effective in practice - it solves 17% more formulas over a range of benchmarks and achieves up to 100x runtime improvement over a state-of-the-art SMT solver.
Single lens off-chip cellphone microscopy (2012)

Within the last few years, cellphone subscriptions have widely spread and now cover even the remotest parts of the planet. Adequate access to healthcare, however, is not widely available, especially in developing countries. We propose a new approach to converting cellphones into low-cost scientific devices for microscopy. Cellphone microscopes have the potential to revolutionize health-related screening and analysis for a variety of applications, including blood and water tests. Our optical system is more flexible than previously proposed mobile microscopes and allows for wide field of view panoramic imaging, the acquisition of parallax, and coded background illumination, which optically enhances the contrast of transparent and refractive specimens.

ISOLATION PROFILE LINER HELPS STABILIZE PROBLEM WELL BORES (1995)

An expandable full-bore liner can cover long, lost circulation zones to eliminate the need for intermediate casing strings. This liner has also successfully repaired various casing problems in producing wells. The TatNIPIneft Institute, which is the largest oil and gas research institute in Tatarstan, has designed and patented an isolation profile liner, which was initially manufactured to eliminate the need for intermediate casing strings because of lost circulation or pressure depleted formations. To date, the liner has been successfully installed in approximately 850 wells throughout Russia. The isolation profile liner is constructed from a proprietary alloy that can be expanded from a collapsed state once the tool is run to the proper setting depth. To maintain the full working diameter of the well bore, the driller must underream the hole slightly above, below, and the across the problem zone. The liner is then expanded into the underreamed portion of the hole by using pump pressure an da specially designed expansion tool. An epoxy material applied to the outside of the profile liner adheres to the borehole wall, thus keeping the liner in place.
Multiobjective optimization of large-scale structures (1993)

This paper presents a multiobjective optimization algorithm based on generalized compound scaling techniques. The algorithm handles any number of objective functions, similar to handling behavior constraints. This technique generates a partial Pareto set while solving the optimization problem. A reliability-ba sed decision criterion is used for selecting the best compromise design. The example cases considered in this work include various disciplines in airframe structures, such as stress, displacement, and frequency with hundreds of design variables and constraints. This paper also discusses the concept of Pareto-optima l solutions in the context of a multiobjective structural optimization problem and the commonly used methods of generating Pareto-optimal solutions.
Control of ion energy distributions using a pulsed plasma with synchronous bias on a boundary electrode (2011)

Ion energy distributions (IEDs) on a grounded substrate in a Faraday-shielded argon inductively coupled plasma were measured with a retarding field energy analyzer. A Langmuir probe was also used to measure space- and time-resolved plasma parameters. IEDs and plasma parameters were studied with continuous or pulsed positive dc bias voltage on a ‘boundary electrode’ in contact with the plasma. For continuous wave plasmas without applied bias, the IED exhibited a single broad peak at the plasma potential. Applying a continuous positive dc bias on the boundary electrode shifted the peak of the IED to higher energy. Application of a synchronous dc bias on the boundary electrode during the afterglow of a pulsed plasma resulted in a double-peaked IED. The mean energies of the two peaks, as well as the peak separation, were controlled by adjusting the applied dc bias and the discharge pressure. The full width at half maximum (FWHM) of the peak corresponding to the synchronous dc bias diminished with decreasing electron temperature. The FWHM was controlled by varying the time window in the afterglow during which dc bias was applied. (Some figures in this article are in colour only in the electronic version)
Reconsidering Domestication Of Legumes Versus Cereals In The Ancient Near East (2009)

In this paper, we discuss, from both biological and cultural perspectives, the ancient human-plant liaison that gave rise to Near Eastern agriculture. We explain the biological aspects of Near Eastern plant domestication by a comparative analysis of legume vs. cereal crop evolution. This comparison is illustrated by the natural distribution, ecological affinity, physiology, population structure, floral biology, growth habit, plant stature, seed dispersal mode, and seed dormancy of both wild and domesticated plants of these crop groups. We discuss the differences between Near Eastern legumes and cereals with regard to each of the above aspects, and we highlight the relevance of these differences with regard to Neolithic decision-making, adoption for farming, and subsequent evolution under domestication. We reached the following conclusions: (1) Near Eastern legumes underwent different evolutionary trajectories under domestication as compared with their companion cereals, despite apparent similarities between selection under domestication of both crop groups. (2) Careful comparison of pea, lentil, and chickpea shows that each of the Near Eastern legume crops has a unique evolutionary history in its own right, and this also holds true for the cereal crops. (3) The evolutionary history of each of the Near Eastern crops, prior to as well as after domestication, is well-reflected in its adaptation profile in present-day cropping systems, which determines each crop's relative economic importance in different world regions (e.g., chickpea is a major pulse in the Indian subcontinent, and pea is a more important crop in temperate regions, while barley has the widest adaptation, extending from high-latitude temperate regions to semi-arid Mediterranean systems). (4) Ancient choice-making as reflected in the founder crops repertoire, involved nutritional considerations that may have outweighed grain yield per area and/or time unit criteria.
Power capability of salient pole permanent magnet synchronous motors in variable speed drive applications (1990)

A constant-parameter equivalent circuit model that neglects motor losses is used to determine the effects of direct and quadrature reactances and open-circuit voltage on the power capability of salient-pole permanent-magnet motors in variable-speed drive applications. It is shown that peak power capability over a range of speeds can be obtained by proper control of the magnitude and phase of the armature current. Due to the voltage constraint imposed at the motor terminals, the power capability will fall to zero for most motor designs at a given high speed. A simple relationship between the motor open-circuit voltage and the direct axis reactance is derived to obtain motor designs that, even with this voltage constraint in place, extend their theoretical power capability, neglecting losses, to infinite speed. All results are presented in normalized curves using a per-unit system.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">></ETX>

Nonuniversality in the spectral properties of time-reversal-invariant microwave networks and quantum graphs (2017)

We present experimental and numerical results for the long-range fluctuation properties in the spectra of quantum graphs with chaotic classical dynamics and preserved time-reversal invariance. Such systems are generally believed to provide an ideal basis for the experimental study of problems originating from the field of quantum chaos and random matrix theory. Our objective is to demonstrate that this is true only for short-range fluctuation properties in the spectra, whereas the observation of deviations in the long-range fluctuations is typical for quantum graphs. This may be attributed to the unavoidable occurrence of short periodic orbits, which explore only the individual bonds forming a graph and thus do not sense the chaoticity of its dynamics. In order to corroborate our supposition, we performed numerous experimental and corresponding numerical studies of long-range fluctuations in terms of the number variance and the power spectrum. Furthermore, we evaluated length spectra and compared them to semiclassical ones obtained from the exact trace formula for quantum graphs.
