Metamodel-based UML Notations for Domain-specific Languages (2007)

Abstract We present a metamodel-based approach for specifying uml notations for domain-specific modeling languages. Traditionally, domain specific languages are either defined by uml profiles or using metamodels. We provide a generic integration of these two methods supporting arbitrary uml profiles and metamodels. Our approach provides a bidirectional mapping between the uml notation and the metamodel of the domain specific language. We use ocl constraints that are embedded into the metamodel, for describing the mapping between the uml notation and the metamodel. Moreover, we describe an implementation, as ArgoUML-plugin, for arbitrary SecureUML dialects.
Novel Keratinase from <i>Bacillus subtilis</i> S14 Exhibiting Remarkable Dehairing Capabilities (2005)

We report the isolation of a keratinolytic-producing Bacillus subtilis strain and the characterization of the exceptional dehairing properties of its subtilisin-like keratinase. This enzyme can be an alternative to sodium sulfide, the major pollutant from tanneries, and may completely replace it. Its unique nonactivity upon collagen enhances its industrial potential.

Mn-Salen Catalyzed Asymmetric Epoxidation of 1,3-Cycloalkadienes and Dialkylsubstituted Z-Olefins (1995)

Epoxidation of 1,3-cycloalkadienes with Mn-salen catalyst 1 at the reduced temperature (-18 °C) was found to show high enantioselectivity ranging from 82-94% ee. Epoxidation of (Z)-1-cyclohexyl-1-propene was also found to proceed with good enantioselectivity of 82% ee.
Memory allocation and higher-order functions (1987)

This paper presents a constant-time marking-collecting algorithm to efficiently implement recursion with a general heap memory rather than with a vectorial stack, in a context of frequent captures of continuations. It has been seen to reduce the 80% garbage collection overhead to less than 5% on average.The algorithm has been built into a virtual machine to efficiently implement at the assembly level the Actor language PLASMA, an Actor-oriented version of PROLOG and a variant of SCHEME, currently in use on 8086, 68000 and Vax.The rationale to use the heap memory is that continuations are available via a single pointer in a unified memory and can be shared optimally when recurrently captured, which is simply impossible using a strategy based on stack recopy. Further, non-captured continuations can be incrementally garbage collected on the fly.Part I describes the elementary recursive instructions of the virtual machine. Part II presents and proves the marking-collecting strategy. Part III safely generalizes the transformation "call + return = branch" in a way compatible with the possible capture of the current continuation. An appendix relates its integration in the Virtual Scheme Machine supporting Scheme 84.
Subminiature hearing aid microphones (1985)

Electret microphones have played a key role in the miniaturization of hearing aids since 1970. With the passage of time their good stability finally is being confirmed with measured values of only 1.5dB loss in output after 15 years. Today's electrets help to fit hearing aids into the ear canal without sacrifice of performance even though the receiver is placed much closer. New microphones use a diaphragm 1 to 2 micron in thickness to reduce vibration-induced distortion and feed back from the receiver. Teflon back-electrets provide bias and close-coupled preamps impedance matching to the amplifier.
Architectural support for register allocation in the presence of aliasing (1990)

High performance computer architectures use registers to provide high speed access to data operands, to provide short names for operands, and to reduce memory traffic for accesses to these operands. The possibility of aliasing in a program segment reduces the quality of code that a compiler can produce by necessitating that memory and register copies of variables that have been allocated to registers be kept consistent. A hardware support mechanism is presented that permits all classes of data objects, including dynamically allocated objects and array elements, to be held in registers without consideration of possible aliases and without requiring that the generated code maintain consistency between register and memory copies of variables. Use of this approach permits programs to benefit from the speed advantages and reduced memory traffic associated with register storage, obviates the need to collect aliasing information for use in register allocation, and reduces instruction traffic by eliminating code used solely to maintain register-memory consistency. The support hardware can be implemented using known hardware technology and without increasing the cycle time of the processor.
Charge transport in amorphous molecular materials (2005)

Charge carrier drift mobilities of a series of hole-transporting amorphous molecular materials have been determined by a time-of-flight method. Electric-field and temperature dependencies of carrier mobilities have been analyzed in terms of the disorder formalism, and charge transport in amorphous molecular materials is discussed in relation to molecular structures. Hole-transporting amorphous molecular materials with high mobilities of the order of 10<sup>-2</sup>cm<sup>2</sup>V<sup>-1</sup>s<sup>-1</sup> have been developed.
Fluoro-olefin chemistry. Part 11. Some reactions of perfluoro-3-methylbut-1-ene under ionic and free-radical conditions (1979)

The reactions of hydrogen bromide, N-bromobistrifluoromethylamine, methanethiol, and trimethylsilane with perfluoro-3-methylbut-1-ene under free-radical conditions proceed by attack by Br·, (CF3)2N·, MeS·, and Me3Si· exclusively at the terminal CF2 group. Fluoride ion rearranges the olefin to perfluoro-2-methylbut-2-ene, and methoxide ion affords a complex mixture of products derived from both the reactant and rearranged olefins. Dimethylamine gives the unexpected 1 : 1 adduct, (CF3)2CH·CF2·CF2·NMe2 and the corresponding amide (CF3)2CH·CF2·CO·NMe2. Catalytic hydrogenation of the olefin proceeds normally to give 1H,2H-3-trifluoromethylheptafluorobutane.

Imaging findings and pharmacokinetics of 111-indium ZME-018 monoclonal antibody (MoAb) in malignant melanoma (1985)

Reducing energy barriers of chemical reactions is the never-ending endeavor of chemists. Inspired by the high reactivity of primary cells, we develop a nanosized fuel cell catalyst (denoted as nanomicrocell catalyst), consisting of integrated electrode pairs, conductive matrices and electrolytes, to improve the chemical reactivity. Specifically, the anodes are Pd species which is combining with the electron-rich N atoms in B-and-N co-doped carbon dots; the cathodes are electron-deficient B atoms; and the conductive matrices are B-and-N co-doped carbon dots which are connecting with the electrode pairs. Similar to the reactivity of primary cells, the catalytic properties of the nanomicrocell catalyst in hydrogenation of benzaldehyde are depending on the properties of electrode pairs, conductive matrices and electrolytes. The unique catalytic properties are attributed to the different substrate adsorption capability and catalytic properties of paired electrodes, and the easy migration of electrons and charge carriers, which could improve the synergetic effect between paired active sites. Therefore, this work may open up a new window for designed synthesis of advanced catalysts which could highly lower the energy barriers of chemical reactions.
<i>Francisella</i> sp., an emerging pathogen of tilapia, <i>Oreochromis niloticus</i> (L.), in Costa Rica (2009)

Francisella sp. is an emergent bacterial pathogen that causes acute to chronic disease in warm and cold water cultured and wild fish species. During the past 3 years, the bacterium has been detected in tilapia, Oreochromis niloticus, cultured in Costa Rica. Infected fish presented non-specific clinical signs, such as erratic swimming, anorexia, anaemia, exophthalmia and high mortality. Upon macroscopic and microscopic examination, several internal organs (mainly spleen and kidney) were enlarged and contained white nodules. Histological examination revealed the presence of multifocal granulomatous lesions, with the presence of numerous small, pleomorphic, cocco-bacilli. The bacteria were isolated from infected tilapia on selective media and grown on several media with and without antibiotics. Specific PCR primers to the Francisella genus were used to confirm the preliminary diagnoses. In comparison with several bacterial 16S rRNA sequences, our isolate was found to share 99% identity with other Fransicella spp. isolated from fish, and more than 97% identity to the human pathogen Francisella tularensis. Koch's postulates were fulfilled after experimental intraperitoneal and gill exposure challenges.
InGaAs/InAlAs Avalanche Photodiode With Low Dark Current for High-Speed Operation (2015)

Waveguide InGaAs/InAlAs avalanche photodiodes (APDs) with high bandwidths (>40 GHz) and low dark current (<;50 nA at 90% of breakdown voltage) were demonstrated. The excess noise is low, corresponding to k ~ 0.2 line in the local excess noise model. Using these values bit error rate (BER) was calculated to assess the potential of our APDs. Calculated sensitivities of -21.5 dBm at 25 Gb/s and -14.2 dBm at 40 Gb/s are predicted for a BER of 10 <sup xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">-10</sup> . Analysis showed that with lower amplifier noise, the low dark current and low excess noise from our APDs are necessary to optimize the sensitivity.
A Study of the Properties of Acid-modified Multicomponent Copolyester Fibre (1998)

By applying conventional analytical methods in this study, the following conclusions are reached: the saturation value of acid-modified multicomponent copolyesterification fibre (acid-modified polyester fibre) is 1.74, and this type of fibre is therefore suitable for dyeing in both medium and light colours by using cationic dyes; the level of crystallization of the fibre is lower than that of PET fibre; the third-monomer (SIPM) content in the fibre will be reduced by about 8% by the ‘alkali treatment’ used in the dyeing and finishing processes; by determining and analysing the dye-uptake curves against time and temperature when the fibre is dyed with cationic dyes, it is concluded that the key factors in the dyeing process are the dyeing temperature of 100°C and the time for heat preservation; moreover, the addition of sodium sulphate will help the level-dyeing process hut lower the dye-uptake.
Medical decision support: experience with implementing the Arden Syntax at the Columbia-Presbyterian Medical Center. (1995)

We began implementation of a medical decision support system (MDSS) at the Columbia-Presbyterian Medical Center (CPMC) using the Arden Syntax in 1992. The Clinical Event Monitor which executes the Medical Logic Modules (MLMs) runs on a mainframe computer. Data are stored in a relational database and accessed via PL/I programs known as Data Access Modules (DAMs). Currently we have 18 clinical, 12 research and 10 administrative MLMs. On average, the clinical MLMs generate 50357 simple interpretations of laboratory data and 1080 alerts each month. The number of alerts actually read varies by subject of the MLM from 32.4% to 73.5%. Most simple interpretations are not read at all. A significant problem of MLMs is maintenance, and changes in laboratory testing and message output can impair MLM execution significantly. We are now using relational database technology and coded MLM output to study the process outcome of our MDSS.
The effect and safety of an ephedrine/caffeine compound compared to ephedrine, caffeine and placebo in obese subjects on an energy restricted diet. A double blind trial. (1992)

The sympathomimetic agent ephedrine has potent thermogenic and anti-obesity properties in rodents. The effect is markedly enhanced by caffeine, while caffeine given alone has no effect. This study was undertaken to find out if a similar weight reducing synergism between ephedrine and caffeine is present in obese patients. In a randomized, placebo-controlled, double blind study, 180 obese patients were treated by diet (4.2 MJ/day) and either an ephedrine/caffeine combination (20mg/200mg), ephedrine (20 mg), caffeine (200 mg) or placebo three times a day for 24 weeks. Withdrawals were distributed equally in the four groups, and 141 patients completed the trial. Mean weight losses was significantly greater with the combination than with placebo from week 8 to week 24 (ephedrine/caffeine, 16.6 +/- 6.8 kg vs. placebo, 13.2 +/- 6.6 kg (mean +/- s.d.), P = 0.0015). Weight loss in both the ephedrine and the caffeine groups was similar to that of the placebo group. Side effects (tremor, insomnia and dizziness) were transient and after eight weeks of treatment they had reached placebo levels. Systolic and diastolic blood pressure fell similarly in all four groups. We conclude, that in analogy with animal studies, the ephedrine/caffeine combination is effective, while caffeine and ephedrine separately are ineffective for the treatment of human obesity.
Antioxidant Capacity and Phenolic Content of Spinach As Affected by Genetics and Growing Season (2002)

Total phenolic content and antioxidant capacity of 11 commercial cultivars and 15 advanced breeding lines of spinach were determined over two growing seasons known to vary in biotic and abiotic stresses. Flavonoid composition and content of fall-grown commercial cultivars and advanced breeding lines were also determined. Over-winter spinach, which was planted in late fall and harvested in the spring, had much higher levels of total phenolics and antioxidant capacity than spinach planted in early fall and harvested in late fall, indicating that growing conditions, as well as biotic and abiotic stresses, influenced phenolic metabolism. Genotype also appeared to play an important role in affecting phenolic metabolism and antioxidant capacity in spinach. Advanced breeding lines of spinach, which show increased disease resistance, had higher levels of total phenolics, individual and total flavonoids, and antioxidant capacity than commercial cultivars. Our results indicate that plant breeders can select for increased phenolic content to increase antioxidant capacity in spinach cultivars, or the crops can be grown in different seasons or under certain stress conditions to elevate levels of antioxidants.
A reliable multicast routing protocol based on recovery points in mobile ad-hoc networks (2005)

Multicasting is an essential service for mobile ad-hoc networks. A major challenge of multicasting in mobile ad-hoc networks is unstable forwarding path. This work presents a reliable multicasting protocol for mobile ad-hoc networks. A virtual backbone is used as a shared structure for multiple sessions, and a lost packet recovery scheme is developed for reliable packet transmission, called recovery point (RP) scheme. The RP scheme keeps the data packets from the source for recovering lost packets for its downstream RPs. A mergence scheme for RP is proposed to avoid the excessive control overhead. This scheme can be used to improve reliability of the traditional non-acknowledged multicasting approach. Experiments were conducted to evaluate the proposed multicasting scheme and the results demonstrate that our scheme outperforms other schemes in terms of packet delivery ratio and multicast efficiency. Furthermore, the simulation results also demonstrate that our approach is stable in networks with high mobility. (7 pages)

A high gain SiGe-GaN switching power amplifier in the GHz-range (2012)

This paper reports a GaN switching power amplifier with a complementary SiGe driver stage in a hybrid setup. The gain of the overall amplifier module is higher than 40 dB. Drain efficiency and an overall lineup efficiency of 60 % and 47 % respectively could be achieved at a bit rate of 1 Gbps when operating with a periodic drive signal. An operation up to 4 Gbps using a pseudo random pulse sequence is demonstrated. To the author's knowledge, this is the first time a GaN switching amplifier with a SiGe driver is demonstrated. Furthermore, such a high gain combined with the efficiencies at bit rates above 1 Gbps has not been presented yet.
Mass Spectrometry and Glycomics (2010)

Glycosylation defines the adhesive properties of animal cell surfaces and the surrounding extracellular environments. Because cells respond to stimuli by altering glycan expression, glycan structures vary according to spatial location in tissue and temporal factors. These dynamic structural expression patterns, combined with the essential roles glycans play in physiology, drive the need for analytical methods for glycoconjugates. In addition, recombinant glycoprotein drug products represent a multibillion dollar market. Effective analytical methods are needed to speed the identification of new targets and the development of industrial glycoprotein products, both new and biosimilar. Mass spectrometry is an enabling technology in glycomics. This review summarizes mass spectrometry of glycoconjugate glycans. The intent is to summarize appropriate methods for glycans given their chemical properties as distinct from those of proteins, lipids, and small molecule metabolites. Special attention is given to the uses of mass spectral profiling for glycomics with respect to the N-linked, O-linked, ganglioside, and glycosaminoglycan compound classes. Next, the uses of tandem mass spectrometry of glycans are summarized. The review finishes with an update on mass spectral glycoproteomics.
Synthesis of Core−Shell PtCo Nanocrystals (2003)

Monodisperse, bimetallic PtCo nanoparticles with a controllable core−shell structure have been synthesized by a new two-stage route. The process involves thermal decomposition of cobalt carbonyl in the presence of a nanosized platinum (Pt) dispersion, where the thickness of the Co shell can be controlled by changing the amount of cobalt carbonyl. The synthesized particles reveal a narrow size distribution with average diameters of 2.6 for Pt and a maximum of 7.6 nm for PtCo. Transmission electron microscopy (TEM), energy-dispersive X-ray spectrometry (EDX), optical spectroscopy, and superconducting quantum interference (SQUID) magnetometry were used for characterization of the bimetallic system.
Accelerated ethylene production as related to changes in lipids and electrolyte leakage during senescence of petals of cut carnations <i>(Dianthus caryophyllus)</i> (1987)

Conditions inhibiting the action of (supply of silver thiosulfate) or the synthesis of (supply of α‐aminooxyacetic acid) ethylene, prolonged the vase‐life of carnation ( Dianthus caryophyllus L. cv. Ember) flowers. On the other hand, conditions which provoked an advance in the time of appearance of the ethylene rise (previous exposure to exogenous ethylene), accelerated senescence. This action on the morphological changes was accompanied by an effect on the efflux of electrolytes, which was advanced or delayed depending on the type of treatment, in comparison with the control. The various factors acting on ethylene production also affected membrane lipids. Those which suppressed or delayed the ethylene rise, slowed down the degradation of the total and free fatty acids and the increase in the level of saturation of the chains. The opposite was observed when the ethylene peak occurred early. There was no correlation between the time of appearance of the burst of ethylene and the time of onset of lipid breakdown. A 48 h water stress provoked neither an advance in the time of appearance of the ethylene peak nor an acceleration in lipid breakdown on return to normal conditions.
A new system for the acquisition of ultrasonic multicompression strain images of the human prostate in vivo (1999)

We describe a novel recording system for the acquisition of multicompression strain images of the human prostate in vivo. The force at the tip of an ultrasonic transrectal probe is measured continuously, and ultrasonic RF-images are acquired consecutively at specified levels of compression. The acquired image sequence is processed by conventional cross-correlation techniques to obtain time shift estimates and corresponding strain images. We present phantom measurements as well as in vivo results and discuss the advantages and restrictions of the proposed system.
Application-bypass broadcast in MPICH over GM (2003)

Processes of a parallel program can become unsynchronized, or skewed, during the course of running an application. Processes can become skewed as a result of unbalanced or asymmetric rode, or through the use of heterogeneous systems, where nodes in the system have different performance characteristics, as well as random, unpredictable effects such as the processes not being started at exactly the same time, or processors receiving interrupts during computation. Geographically distributed systems may have more severe skew because of variable communication times. Such skew can have a significant impact on the performance of collective communication operations which impose an implicit synchronization. The broadcast operation in MPICH is one such operation. An application-bypass broadcast operation is one which does not depend on the application running at a process to make progress. Such an operation would not be as sensitive to process skew. This paper describes the design and implementation of an application-bypass broadcast operation. We evaluated the implementation and find a factor of improvement of up to 16 for application-bypass broadcast compared to non-application-bypass broadcast when processes are skewed. Furthermore we see that as the system size increases, the effects of skew on non-application-bypass broadcast also increase. The application-bypass broadcast is much less sensitive to process skew which makes it more scalable than the non-application-bypass broadcast operation.
