This paper deals with advantages of model-based software engineering approach of critical UAV onboard systems. Application of modern model-based technologies for critical onboard systems development is considered. Rules for critical software engineering at all life cycle stages are defined by functional standards. Mentioned approach implements all requirements of safety standards by automating the most consuming activities like verification and documentation writing. The program for UAV-automatic flight control system control loop simulation and visualization is developed. Use of the mentioned approach allows to facilitate UAV onboard systems software engineering, analyze and certification process.
H- and J-Aggregate Behavior in Polymeric Semiconductors (2014)

Aggregates of conjugated polymers exhibit two classes of fundamental electronic interactions: those occurring within a given chain and those occurring between chains. The impact of such excitonic interactions on the photophysics of polymer films can be understood using concepts of J- and H-aggregation originally developed by Kasha and coworkers to treat aggregates of small molecules. In polymer assemblies, intrachain through-bond interactions lead to J-aggregate behavior, whereas interchain Coulombic interactions lead to H-aggregate behavior. The photophysics of common emissive conjugated polymer films are determined by a competition between intrachain, J-favoring interactions and interchain, H-favoring interactions. We review formalisms describing absorption and photoluminescence lineshapes, based on intra- and intermolecular excitonic coupling, electron-vibrational coupling, and correlated energetic disorder. Examples include regioregular polythiophenes, pheneylene-vinylenes, and polydiacetylene.
RETRACTED ARTICLE: An apoptosis-enhancing drug overcomes platinum resistance in a tumour-initiating subpopulation of ovarian cancer (2015)

High-grade serous ovarian cancers (HGSCs) are deadly malignancies that relapse despite carboplatin chemotherapy. Here we show that 16 independent primary HGSC samples contain a CA125-negative population enriched for carboplatin-resistant cancer initiating cells. Transcriptome analysis reveals upregulation of homologous recombination DNA repair and anti-apoptotic signals in this population. While treatment with carboplatin enriches for CA125-negative cells, co-treatment with carboplatin and birinapant eliminates these cells in HGSCs expressing high levels of the inhibitor of apoptosis protein cIAP in the CA125-negative population. Birinapant sensitizes CA125-negative cells to carboplatin by mediating degradation of cIAP causing cleavage of caspase 8 and restoration of apoptosis. This co-therapy significantly improves disease-free survival in vivo compared with either therapy alone in tumour-bearing mice. These findings suggest that therapeutic strategies that target CA125-negative cells may be useful in the treatment of HGSC.
Multipath beamforming for UWB: channel unknown at the receiver (2003)

We study two adaptive transmission approaches that coherently combine the energy from the first several reflected paths of the ultra-wideband (UWB) channel. Thus, the signal energy at the output of a non-adaptive correlator is enhanced. The two multipath beamforming techniques, which are applicable to the DSC-UWB system in a LOS environment, suggest selecting a multilevel spreading sequence based on the signs of the first several multipath coefficients. By employing the beamforming approach, increased fluctuations in the multipath components power, are followed by an increase in the beamforming gain over m-, and single impulse sequences.
Infrared Reflection Studies of the Oxidation of Copper and Iron (1969)

Infrared multiple reflectance spectra were used to record the growth of oxide films on copper and iron mirrors. Cuprous oxide and cupric oxide films were readily distinguished since they exhibit intense single bands at 640 cm−1 and ∼560 cm−1, respectively. Iron oxide films of a single composition also exhibit highly characteristic bands in the 230 to 1100 cm−1 region of the reflectance spectra. Spectra of mixed iron oxide films were composed of many highly overlapping bands making quantitative interpretations difficult. The intensities of the infrared bands from the copper oxide and iron oxide films were directly proportional to the oxide film thicknesses. Using a seven reflection −73° incidence optical accessory, sensitivity to detect oxide films as thin as about 5Aå was achieved.
2-20-GHz GaAs Traveling-Wave Power Amplifier (1984)

Power amplification in FET traveling-wave amplifiers is examined, and the mechanisms which limit power capability of the amplifier are identified. Design considerations for power amplification are discussed. A novel single-stage and two-stage monolithic GaAs traveling-wave power amplifier with over 250-mW power output in the 2-20-GHz frequency range is described.

Scalable virtual machine deployment using VM image caches (2013)

In IaaS clouds, VM startup times are frequently perceived as slow, negatively impacting both dynamic scaling of web applications and the startup of high-performance computing applications consisting of many VM nodes. A significant part of the startup time is due to the large transfers of VM image content from a storage node to the actual compute nodes, even when copy-on-write schemes are used. We have observed that only a tiny part of the VM image is needed for the VM to be able to start up. Based on this observation, we propose using small caches for VM images to overcome the VM startup bottlenecks. We have implemented such caches as an extension to KVM/QEMU. Our evaluation with up to 64 VMs shows that using our caches reduces the time needed for simultaneous VM startups to the one of a single VM.
3D imaging of biofilms on implants by detection of scattered light with a scanning laser optical tomograph (2011)

Biofilms - communities of microorganisms attached to surfaces - are a constant threat for long-term success in modern implantology. The application of laser scanning microscopy (LSM) has increased the knowledge about microscopic properties of biofilms, whereas a 3D imaging technique for the large scale visualization of bacterial growth and migration on curved and non-transparent surfaces is not realized so far.Towards this goal, we built a scanning laser optical tomography (SLOT) setup detecting scattered laser light to image biofilm on dental implant surfaces. SLOT enables the visualization of living biofilms in 3D by detecting the wavelength-dependent absorption of non-fluorescent stains like e.g. reduced triphenyltetrazolium chloride (TTC) accumulated within metabolically active bacterial cells. Thus, the presented system allows the large scale investigation of vital biofilm structure and in vitro development on cylindrical and non-transparent objects without the need for fluorescent vital staining. We suggest SLOT to be a valuable tool for the structural and volumetric investigation of biofilm formation on implants with sizes up to several millimeters.
From Stability to Permeability of Adhesive Emulsion Bilayers (2012)

Water drops dispersed in chloroform and stabilized with phospholipids become adhesive if a bad solvent for lipids, such as silicone oil, is added to the continuous phase. In this way, two sticking drops are separated by a bilayer of phospholipids. By using microfluidic technologies, we probe the stability and properties of such membranes likewise encountered in foams or vesicles. We first establish the stability diagram of adhering drop pairs as a function of the continuous phase composition. We found two regimes of destabilization of the bilayer. The first one concerns a competition between the dynamics of adhesion and the transport of surfactants toward the interfaces that leads to a dilute surfactant coverage. The second one corresponds to a dense surface coverage where the lifetime distribution of the bilayer exponentially decreases as a signature of a nucleation process. In the stable regime, we observe the propagation of adhesion among a concentrated collection of drops. This is another remarkable illustration of the suction consequence when two close deformable objects are pulled apart. Moreover, the present experimental strategy offers a novel way to study the phase diagrams of bilayers from a single phospholipid to a mixture of phospholipids. Indeed, we detect phase transitions at a liquid-liquid interface that are ruled by the amount of bad solvent. Finally, we probe the transport of water molecules through the bilayer and show that its permeability is linked to the adhesion energy that reflects its fluidity.
A Fault-Tolerant Information Processing Concept for Space Vehicles (1971)

A distributed fault-tolerant information processing system is proposed, comprising a central multiprocessor, dedicated local processors, and multiplexed input–output buses connecting them together. The processors in the multiprocessor are duplicated for error detection, which is felt to be less expensive than using coded redundancy of comparable effectiveness. Error recovery is made possible by a triplicated scratchpad memory in each processor. The main multiprocessor memory uses replicated memory for error detection and correction. Local processors use any of three conventional redundancy techniques: voting, duplex pairs with backup, and duplex pairs in independent subsystems.
Theoretical modeling and experimental characterization of a rod-pinch diode (2001)

The rod-pinch diode consists of an annular cathode and a small-diameter anode rod that extends through the hole in the cathode. With high-atomic-number material at the tip of the anode rod, the diode provides a small-area, high-yield x-ray source for pulsed radiography. The diode is operated in positive polarity at peak voltages of 1 to 2 MV with peak total electrical currents of 30–70 kA. Anode rod diameters as small as 0.5 mm are used. When electrode plasma motion is properly included, analysis shows that the diode impedance is determined by space-charge-limited current scaling at low voltage and self-magnetically limited critical current scaling at high voltage. As the current approaches the critical current, the electron beam pinches. When anode plasma forms and ions are produced, a strong pinch occurs at the tip of the rod with current densities exceeding 106 A/cm2. Under these conditions, pinch propagation speeds as high as 0.8 cm/ns are observed along a rod extending well beyond the cathode. Even faster pinch propagation is observed when the rod is replaced with a hollow tube whose wall thickness is much less than an electron range, although the propagation mechanism may be different. The diode displays well-behaved electrical characteristics for aspect ratios of cathode to anode radii that are less than 16. New physics understanding and important properties of the rod-pinch diode are described, and a theoretical diode current model is developed and shown to agree with the experimental results. Results from numerical simulations are consistent with this understanding and support the important role that ions play. In particular, it is shown that, as the ratio of the cathode radius to the anode radius increases, both the Langmuir–Blodgett space-charge-limited current and the magnetically limited critical current increase above previously predicted values.

Preparation of Unsymmetrical Microspheres at the Interfaces (1999)

Many synthetic microspheres are spherical and symmetrical because of the thermodynamical limitations of the reaction systems. We developed modification techniques to prepare spherical microspheres with intrinsic unsymmetry, for example, a microsphere with both an anionic and a cationic part. The modification was performed at the liquid−solid interface. Reactive microspheres with p-nitrophenyl moieties were settled onto the IgG-preadsorbed substrate, and the reaction between the activated ester moieties and IgG molecules proceeded only at the interface upon attachment. After the reaction, the modified microspheres were detached from the substrate with ultrasonication. In another modification at the air−water interface, the dispersion of reactive microspheres in ethanol was first spread on a water surface to produce the monolayer of microspheres, and then hydrolysis at the water side of the monolayer was performed by adding a NaOH aqueous solution to the subphase. After this unsymmetrical hydrolysis, we carried out IgG immobilization with the remaining reactive moieties. In both interface methods, the immobilized IgG molecules were labeled with colloidal gold particles conjugated with anti-IgG antibodies. Transmission electron microscopy indicated that gold particles could be observed on only the immobilized side. Small microspheres were coupled to the reactive microsphere, and its unsymmetry was confirmed by scanning electron microscopy. Such unsymmetrical microspheres will be applicable to the electrical rheology, diagnosis, display technology, and creation of functional devices through the assembling of microspheres.
Who can you trust? [trusted computing] (2004)

The trusted computing group (TCG) was formed in 2003 by AMD, Hewlett-Packard, IBM, Intel and Microsoft as an open alliance to develop a solution to the issue of trust. The group has come up with an approach based on a combination of hardware and software, which it calls a trusted platform module (TPM). The TPM hardware is expressed in a chip that is built into the device it is protecting and that cannot be removed or swapped without such tampering becoming evident. The TPM chip holds user secrets, such as digital IDs and the private key parts of public/private key encryption pairs. It has platform configuration registers that can store information about software environment it is operating in and hardware for generating random numbers and performing cryptographic functions. Together these hardware functions and the software stack that gives access to them is designed to support a number of traditional security functions.
Data integration (2002)

Data integration is the problem of combining data residing at different sources, and providing the user with a unified view of these data. The problem of designing data integration systems is important in current real world applications, and is characterized by a number of issues that are interesting from a theoretical point of view. This document presents on overview of the material to be presented in a tutorial on data integration. The tutorial is focused on some of the theoretical issues that are relevant for data integration. Special attention will be devoted to the following aspects: modeling a data integration application, processing queries in data integration, dealing with inconsistent data sources, and reasoning on queries.
Francesco Durante (2001)

F. D. zählt zu den bedeutendsten Komponisten des neapolitanischen Spätbarock. Er führte zum einen den älteren kontrapunktischen Stil fort und öffnete sich zum anderen den neuen gesanglichen und empfindungsreichen Stilelementen. Gerade auch die gelungene Verbindung strenger Fugenpassagen mit den Prinzipien der Empfindsamkeit machte ihn weit über seine Heimat hinaus bekannt. Eben diese Synthese ist für D.s Instrumentalwerke charakteristisch, deren individueller Stil unterschiedliche Vorbilder erkennen läßt. D.s Ruhm als Komponist gründet sich allerdings in erster Linie auf seine zahlreichen kirchenmusikalischen Werke (entgegen der italienischen Tradition seiner Zeit komponierte er offenbar keine Opern).

Synthesis of Mixed Acid Anhydrides from Methane and Carbon Dioxide in Acid Solvents (2003)

[reaction: see text] The reaction of CH(4) with CO(2) has been performed in anhydrous acids using VO(acac)(2) and K(2)S(2)O(8) as promoters. NMR analysis establishes that the primary product is a mixed anhydride of acetic acid and the acid solvent. In sulfuric acid, the overall reaction is CH(4) + CO(2) + SO(3) --> CH(3)C(O)-O-SO(3)H. Hydrolysis of the mixed anhydride produces acetic acid and the solvent acid. When trifluoroacetic acid is the solvent, acetic acid is primarily formed via the reaction CH(4) + CF(3)COOH --> CH(3)COOH + CHF(3).
Human iPSC-derived myocardium-on-chip with capillary-like flow for personalized medicine (2017)

The heart wall tissue, or the myocardium, is one of the main targets in cardiovascular disease prevention and treatment. Animal models have not been sufficient in mimicking the human myocardium as evident by the very low clinical translation rates of cardiovascular drugs. Additionally, current <i>in vitro</i> models of the human myocardium possess several shortcomings such as lack of physiologically relevant co-culture of myocardial cells, lack of a 3D biomimetic environment, and the use of non-human cells. In this study, we address these shortcomings through the design and manufacture of a myocardium-on-chip (MOC) using 3D cell-laden hydrogel constructs and human induced pluripotent stem cell (hiPSC) derived myocardial cells. The MOC utilizes 3D spatially controlled co-culture of hiPSC derived cardiomyocytes (iCMs) and hiPSC derived endothelial cells (iECs) integrated among iCMs as well as in capillary-like side channels, to better mimic the microvasculature seen in native myocardium. We first fully characterized iCMs using immunostaining, genetic, and electrochemical analysis and iECs through immunostaining and alignment analysis to ensure their functionality, and then seeded these cells sequentially into the MOC device. We showed that iECs could be cultured within the microfluidic device without losing their phenotypic lineage commitment, and align with the flow upon physiological level shear stresses. We were able to incorporate iCMs within the device in a spatially controlled manner with the help of photocrosslinkable polymers. The iCMs were shown to be viable and functional within the device up to 7 days, and were integrated with the iECs. The iCMs and iECs in this study were derived from the same hiPSC cell line, essentially mimicking the myocardium of an individual human patient. Such devices are essential for personalized medicine studies where the individual drug response of patients with different genetic backgrounds can be tested in a physiologically relevant manner.
<i>OsHAP3</i> genes regulate chloroplast biogenesis in rice (2003)

We have isolated three genes that potentially encode a HAP3/nuclear factor-YB (NF-YB)/CCAAT binding factor-A (CBF-A) subunit of a CCAAT-box binding complex in rice (Oryza sativa), and named them OsHAP3A, OsHAP3B and OsHAP3C. These genes were expressed in various organs including leaves. In the transgenic rice plants with antisense or RNAi construct of OsHAP3A, reduced expression of not only OsHAP3A but also OsHAP3B and OsHAP3C was observed. These plants had pale green leaves, in which the amount of chlorophyll was reduced and chloroplasts were degenerated. Lamella was not well developed and accumulation of starch was not detected. The degenerated chloroplast formation was accompanied by reduced expression of nuclear-encoded photosynthesis genes such as RBCS and CAB, while expression of chloroplast-encoded genes was not affected or rather increased. These results suggest that one or more OsHAP3 genes regulate the expression of nuclear-encoded chloroplast-targeted genes and normal development of chloroplasts.
