Mini-Workshop: Analytical and Numerical Methods in Image and Surface Processing (2005)

In different areas of mathematics and computer science significant progress has been achieved with respect to geometric modeling, the processing of detailed surface models and geometric methods in morphological image processing. In contrast to classical tools in approximation theory such as spline curves and surfaces these new approaches rely on methods from the calculus of variations and geometric evolution problems. As examples we would like to mention here: Recently it has become clear that even though the applications areas differ significantly the methodological overlap is enormous. E.g. currently Willmore flow is one of the hot topics in geometric analysis and at the same time it turned out to be an adequate approach for the restoration of destroyed surfaces. Simultaneously the Willmore energy is a fundamental building block in variational methods of morphological image processing. Indeed as for surfaces it can be used for restoration and the disocclusion of images. Furthermore, it enters important fairness criteria in geometry processing and the generation of C^1 smooth surface models. The progress in this new, active and already very successful research field has its roots in originally completely different disciplines of mathematics and computer science. Hence, an exchange of different methodologies and a joining of activities is very promising. This was the intention of the mini workshop. To achieve this goal researchers from completely different areas of mathematics and mathematically oriented computer science were invited to share their point of view and their recent achievements with others. The intention of this mini-workshop was to initiate stronger exchange, to encourage the exploration of synergies and the building of bridges between the different disciplines and the different types of approaches for closely related research fields. In particular we intended to bring together people from Let us unroll one of these synergy fields: The organizers contributed introductory talks into the different fields to stimulate discussion and interaction. In parallel to this mini workshop another mini workshop on fluid interfaces took place. Together with the organizers of the latter workshop we arranged for several joined talks on the common interest field of geometric evolution problems by participants of both workshops. This interplay turned out to be very fruitful and inspiring. One Thursday evening we had a longer evening talk on a new approach for the discretization of fluid motion given by Peter Schröder.
ARCHITECTURE AND DESIGN OF AN 8-BIT FLUX-1 SUPERCONDUCTOR RSFQ MICROPROCESSOR (2002)

The first single-chip superconductor FLUX-1 microprocessor has been designed in the Rapid Single Flux Quantum (RSFQ) logic and fabricated using 4 kA/cm 2 , 1.75-μm Nb/AlOx/Nb Josephson junction technology as a result of the collaboration between SUNY Stony Brook and TRW, Inc. A FLUX-1 chip represents an 8-bit deeply pipelined microprocessor prototype with a target clock frequency of 17-20 GHz. A new parallel partitioned architecture has been developed in order to tolerate interconnect delays and fill long FLUX-1 processor pipelines with useful instructions. The processor includes the 16 × 32-bit pipelined instruction memory, 8 integer arithmetic-logic units interleaved with 8 registers, the branch unit, and I/O ports for 5-GHz chip-to-chip communication over Nb microstrip lines on a chip carrier. The FLUX-1 instruction set consists of ~25 arithmetic, logical, and control instructions. A FLUX-1 microprocessor chip contains 65,759 Josephson junctions on a 10.6 mm × 13.2 mm die with flip-chip packaging. First FLUX-1 chips fabricated in August 2001 are currently under testing at TRW, Inc.
Synthesis of Nanostructured Silicon Carbide through an Integrated Mechanical and Thermal Activation Process (2002)

Changes of crystal structures and microstructures of SiO 2 and graphite powder mixtures induced by high‐energy milling, the effect of these changes on the reactivity of reactants, and the mechanism of enhanced SiC formation have been studied using a variety of analytical instruments, including X‐ray diffractometry, scanning electron microscopy, transmission electron microscopy, solid‐state 29 Si nuclear magnetic resonance, and nitrogen adsorption (i.e., the BET method). High‐energy milling before carbothermic reduction leads to substantial changes in the structural and energy states of the reactants, which in turn increases the reactivity of the reactants and enhances the formation of nanostructured SiC particles. Furthermore, the structural and energy‐state changes contribute to the enhanced SiC formation through the increased reaction kinetics as well as the increased reaction driving force.
Cultural and phylogenetic analysis of mixed microbial populations found in natural and commercial bioleaching environments (1994)

A range of autotrophic and heterotrophic enrichment cultures were established to determine the cultural bacterial diversity present in samples obtained from the acidic runoff of a chalcocite overburden heap and from laboratory-scale (1- to 4-liter) batch and continuous bioreactors which were being used for the commercial assessment of the bioleachability of zinc sulfide ore concentrates. Strains identified as Thiobacillus ferrooxidans, Thiobacillus thiooxidans, "Leptospirillum ferrooxidans," and Acidiphilium cryptum were isolated from both the natural site and the batch bioreactor, but only "L. ferrooxidans," a moderately thermophilic strain of T. thiooxidans, and a moderately thermophilic iron-oxidizing bacterium could be recovered from the continuous bioreactor running under steady-state conditions. Sequence analysis of the 16S rRNA genes of 33 representative strains revealed that all of the strains were closely related to strains which have been sequenced previously and also confirmed the phylogenetic diversity of bacteria present in bioleaching environments.

Evaluation of chamber effects on antenna efficiency measurements using non‐reference antenna methods in two reverberation chambers (2017)

In this study, the evaluation of chamber effects on antenna efficiency measurements using non‐reference antenna (NRA) methods is presented. Two reverberation chambers have been employed and they differ in dimensions and paddle stirrer configurations, therefore the corresponding electrical characteristics such as quality factors, decay constants, and enhanced backscatter coefficients are envisaged to be different. However, it is found that these differences have little influence on the efficiency measurement of antennas‐under‐test (AUTs). The AUTs used for this study were a directional antenna and an omnidirectional antenna. The discrepancy in the efficiency of the two antennas measured between the two chambers is &lt;10% within their operational frequency bands. These results demonstrate that the NRA measurement techniques are robust. Further investigation shows that the directional antenna is slightly more prone to polarisation mismatch than the omnidirectional antenna is. Therefore, polarisation stirring should be implemented when using the NRA methods for antenna efficiency measurement especially for directional antennas.
Smelting Networks For Real Time Cooperative Planning In The Presence Of Uncertainties (1988)

This paper discusses the applicability and limitations of the conventional knowledge representations and Al paradigms in designing algorithms for multi-sensor fusion for the uncertainty prone multiple target tracking (MTT) problem. A knowledge-based framework for solution to this problem necessitates developing mechansims for efficient online knowledge acquisition and exploration of alternate knowledge representations as the existing structures prove inadequate in this context. In this paper we describe the use of Smelting Networks for knowledge acquisition, target state representation, resolution of sensor ambiguities and environmental uncertainties. These networks are drawn from a biological cooperative phenomenon and used to enrapture situational constraints, determine track-to-target associations and avoid generation of redundant associations for trajectory estimation.

Constellation labeling optimization for bit-interleaved coded APSK (2016)

This paper investigates the constellation and mapping optimization for amplitude phase shift keying (APSK) modulation, which is deployed in Digital Video Broadcasting Satellite - Second Generation (DVB-S2) and Digital Video Broadcasting - Satellite services to Handhelds (DVB-SH) broadcasting standards due to its merits of power and spectral efficiency together with the robustness against nonlinear distortion. The mapping optimization is performed for 32-APSK according to combined cost functions related to Euclidean distance and mutual information. A Binary switching algorithm and its modified version are used to minimize the cost function and the estimated error between the original and received data. The optimized constellation mapping is tested by combining DVB-S2 standard Low-Density Parity-Check (LDPC) codes in both Bit-Interleaved Coded Modulation (BICM) and BICM with iterative decoding (BICM-ID) systems. The simulated results validate the proposed constellation labeling optimization scheme which yields better performance against conventional 32-APSK constellation defined in DVB-S2 standard.
Statistical Inference in Large Antenna Arrays Under Unknown Noise Pattern (2013)

In this paper, a general information-plus-noise transmission model is assumed, the receiver end of which is composed of a large number of sensors and is unaware of the noise correlation pattern. For this model, under an isotropy assumption between signal and noise left- and right-eigenspaces, a set of results is provided for the receiver to perform statistical eigen-inference on the information part. In particular, we introduce new methods for the detection, counting, and the power and subspace estimation of multiple sources composing the information part of the transmission. The theoretical performance of some of these techniques is also discussed. An exemplary application of these methods to array processing with unknown time correlated noise is then studied in greater detail, leading to a novel MUSIC-like algorithm.
Differential Regulation of Exocytosis by α- and β-SNAPs (2002)

We examined the role of SNAPs, soluble proteins that attach N-ethylmaleimide-sensitive factor (NSF), in regulating exocytosis in single rat adrenal chromaffin cells. Whole-cell dialysis of Ca2+-buffered solution or photolysis of caged-Ca2+ was used to manipulate cytosolic Ca2+ concentration ([Ca2+]i), whereas exocytosis was measured via carbon fiber amperometry or membrane capacitance. Buffering [Ca2+]i to approximately 170 nm produced a mean rate of exocytosis of approximately one amperometric event per minute. Including alpha-SNAP (60 or 500 nm) in the intracellular solution dramatically increased the mean rate of exocytosis. The stimulatory action of alpha-SNAP requires ATP hydrolysis mediated via NSF, because this action was blocked by intracellular dialysis of ATP-gamma-S (2 mm) and could not be mimicked by a mutant alpha-SNAP that does not stimulate the ATPase activity of NSF. This action of alpha-SNAP was significant only at [Ca2+]i between 100 and 300 nm and was not shared by beta-SNAP (500 nm), suggesting that alpha-SNAP enhanced a component of exocytosis that is regulated by a high-affinity Ca2+ sensor. In cells dialyzed with both alpha- and beta-SNAP, the rate of exocytosis was smaller than that produced by alpha-SNAP alone, suggesting that alpha- and beta-SNAP interact competitively. Although only alpha-SNAP stimulated exocytosis at [Ca2+]i between 100 and 300 nm, both alpha- and beta-SNAP isoforms equally slowed the time-dependent rundown of the exocytic response. Our results indicate that alpha- and beta-SNAP have different actions in exocytosis. Thus, the ratio of different isoforms of SNAPs can determine release probability at the levels of [Ca2+]i that are involved in regulation of exocytosis.
Angiotensin type 2 receptor is expressed in human atherosclerotic lesions (2008)

AT2-receptor is expressed in human atherosclerotic plaque. Furthermore, we detected no functionally important role of AT2-receptor expression and found no evidence that ARB treatment regulates AT2-receptor expression.
Matrix-Guest Energy Transfer in Matrix-assisted Laser Desorption (1997)

Molecular dynamics was used to analyze energy transfer rates between matrix and guest molecules in matrix-assisted laser desorption allowing for a large number of internal degrees of freedom. The effect of initial matrix temperature jump on internal energy equilibration times and on guest limiting temperatures has been studied on a model system comprising a pyridine-3-carboxylic acid matrix and leucine enkephalin (Tyr-Gly-Gly-Phe-Leu) guest molecule. It appears that the energy transfer rates between matrix and guest molecules depend on the initial matrix temperature jump. The initial matrix temperature of 900 K leads to incomplete desorption, whereas at 1500 K complete desorption and the formation of an energy-transfer bottleneck was observed. Following the guest center-of-mass at different initial matrix temperatures indicates that in the case of 1500 K and 3000 K the desorption process is complete, whereas at 900 K the guest molecule stays near the matrix surface. In the case of complete desorption deeper embedding of the guest molecules leads to somewhat lower guest limiting temperatures. Uniformly higher limiting temperatures are observed for higher laser irradiance and the increase in burial depth leads to more complete equilibration between the two species. © 1997 John Wiley & Sons, Ltd.

A speech model of acoustic inventories based on asynchronous interpolation (2003)

We propose a speech model that describes acoustic inventories of concatenative synthesizers. The model has the following characteristics: (i) very compact representations and thus high compression ratios are possible, (ii) re-synthezised speech is free of concatenation errors, (iii) the degree of articulation can be controlled explicitly, and (iv) voice transformation is feasible with relatively few additional recordings of a target speaker. The model represents a speech unit as a synthesis of several types of features, each of which has been computed using non-linear, asynchronous interpolation of neighboring basis vectors associated with known phonemic identities. During analysis, basis vectors and transition weights are estimated under a strict diphone assumption using a dynamic time warping approach. During synthesis, the estimated transition weight values are modified to produce changes in duration and articulation effort.
Determination of endogenous methane formation by photoacoustic spectroscopy (2013)

Aerobic methane generation was demonstrated earlier in plants and eukaryotes under various stress conditions. Our aims were to develop a real-time and noninvasive detection system for monitoring the methane production of small animals and humans with our without exposure to various treatments. A near-infrared diode laser technique was employed with photoacoustic spectroscopy to monitor a methane-containing atmosphere online. The whole-body methane generation of anesthetized mice and rats was determined under baseline conditions and following reduction of the intestinal methanogenic flora or after lipopolysaccharide administration. Single-breath methane analyses were also carried out in a cross-sectional clinical study in order to obtain comparative human data. The whole-body methane production of mice was significantly decreased after antibiotic treatment (M: 1.71 ppm cm(-2) 10(3); p25: 1.5 ppm cm(-2) 10(3); p75: 2.11 ppm cm(-2) 10(3)) and increased significantly in endotoxemia (M: 4.53 ppm cm(-2) 10(3); p25: 4.37 ppm cm(-2) 10(3); p75: 5.38 ppm cm(-2) 10(3)), while no difference was observed between the rat groups. The methane content of the exhaled breath in humans was found to be between 0 and 37 ppm. Photoacoustic spectroscopy is a reliable tool with which to monitor the in vivo dynamics of stress-induced methane production in laboratory animals, even in a very low concentration range.

Simple and Efficient Production of Highly Soluble Daidzin Glycosides by Amylosucrase from Deinococcus geothermalis (2019)

Transglycosylation of amylosucrase from <i>Deinococcus geothermalis</i> (DGAS) was performed using daidzin (daidzein-7-<i>O</i>-glucoside). Unlike cyclodextrin glucanotransferase, DGAS led to the production of new daidzin glucosides with high conversion yields (89%). Structures of these daidzin glucosides (i.e., DA2 and DA3) were daidzein-7-<i>O</i>-α-d-glucopyranosyl-(4 → 1)-<i>O</i>-β-d-glucopyranoside (daidzin-4″-<i>O</i>-α-d-glucopyranoside) and daidzein-4'-<i>O</i>-α-d-glucopyranosyl-7-<i>O</i>-α-d-glucopyranosyl-(1 → 4)-<i>O</i>-β-d-glucopyranoside (daidzin-4',4″-<i>O</i>-α-d-diglucopyranoside), respectively. DA2 and DA3 showed increased solubility of 15.4 mM (127-fold) and 203.3 mM (1686-fold) compared with daidzin, respectively. Kinetic studies revealed <i>V</i><sub>max</sub> of 1.0 μM/min and <i>K</i>'<sub>m</sub> of 175 μM for DA3 production based on nonlinear regression. DGAS exhibited substrate inhibition behavior at high sucrose concentrations (700-1500 mM). Taken together, these findings indicate that DGAS can attach a glucose unit to a free C<sub>4</sub>'-OH via an α-linkage and then produce highly water-soluble isoflavone glycosides with a simple donor, moderate reaction conditions, less waste production, and high yield compared with that observed using the existing processes and enzymes.
Role of circumferential flow in the stability of fluid-handling machine rotors (1989)

The recent studies of the dynamic stiffness properties of fluid lubricated bearing and seals by the authors have yielded most of the generalized characteristics discussed and used in this paper. They include bearing and seal nonlinear fluid film properties associated with stiffness, damping, and fluid average circumferential velocity ratio. Analytical relationships yield the rotor system's dynamic stiffness characteristics. This paper shows the combination of these data to provide the fluid-induced rotor stability equations.
Low Levels of Interleukin‐8 and Interferon‐Inducible Protein–10 in Serum Are Associated with Fatal Infections in Acute Lassa Fever (2001)

To investigate the role of inflammatory mediators in the pathogenesis of Lassa fever, the levels of a number of pro- and anti-inflammatory cytokines and chemokines in serum samples collected from hospitalized patients with fatal and nonfatal acute Lassa fever were compared with those from 2 control groups: patients with other febrile illnesses and uninfected individuals. Serum interleukin (IL)-8 and interferon (IFN)-inducible protein (IP)-10 levels were significantly higher in patients with acute nonfatal Lassa fever than in control subjects. In striking contrast, levels of these chemokines were low or undetectable in patients with fatal Lassa fever. IFN-gamma, IL-12, IL-6, and RANTES levels were elevated in all the febrile study groups. Tumor necrosis factor-alpha levels were not elevated in patients with fatal or nonfatal Lassa fever. These data indicate that acute nonfatal Lassa fever is associated with high levels of circulating IL-8 and IP-10 and that low levels or absence of these mediators correlates with a poor outcome.
Local air pollution in fast developing countries (Technical Report) (1995)

Local air pollution is one of the most pressing environmental problems in developing countries.The patterns of local air pollution are similar in many countries. In the initial stages of economic development the demand for energy, coupled to economic expansion, rises sharply. This increased consumption of power for heating, electricity, industrial processes etc. must lead to an increase of emissions. Dust, SO, and secondary products like sulphuric acid are responsible for severe impairments of human health and large scale damage to nature and buildings. Many developing countries have reached this stage of local air pollution or will be exposed to this type of environmental hazards in the near future. Economically developed countries, like the US, Japan and many countries in Western Europe have passed this stage one to three decades ago.In the next phase of economic development transportation, especially by means of lorries and cars becomes a determining factor in local air pollution and cause high concentrations of ozone, peroxyacetyl nitrate (PAN) and other oxidants are present as secondary products of traffic emissions. A number of developing countries are now entering the stage when this "Los Angeles" type of smog starts to become an important environmental problem. Developing countries should benefit from transfer of knowledge obtained in research programs and development of abatement policies in countries, which have been exposed to these problems in the past. But exchange of ideas between developing countries, regarding assessment of air pollution and implementation of emission controls is also very useful to derive optimal abatement strategies.
