<title>Electro-Optic Waveguide Deflectors</title> (1979)

A consistent, analytic technique is used to describe the performance of various wave-guide deflectors, in which a spatially varying phase shift is created electro-optically across the optical beam. We use Fraunhofer diffraction theory to obtain the far field out-put intensity distributions of single prism elements, arrays of identical or phase-staggered prism elements and arrays of channel waveguide elements. The deflection of the optical beam is continuous or discontinuous, depending on the phase distribution across the beam which is determined by the geometry of the device. T.Te calculate the capacitance of the different interdigital electrode structures, with constant and linearly varying gap-widths; the values are in good agreement with experimental measurements. The performance capabilities of different deflectors are assessed in terms of number of resolvable spots, power, bandwidth and crosstalk. Simple phase distributions are shown to be useful for determining most deflector characteristics, including the power per unit bandwidth.
PAS‐cal: A repetitive peptide sequence calibration standard for MALDI mass spectrometry (2014)

Mass spectrometers equipped with matrix-assisted laser desorption/ionization (MALDI-MS) require frequent multipoint calibration to obtain good mass accuracy over a wide mass range and across large numbers of samples. In this study, we introduce a new synthetic peptide mass calibration standard termed PAS-cal tailored for MALDI-MS based bottom-up proteomics. This standard consists of 30 peptides between 8 and 37 amino acids long and each constructed to contain repetitive sequences of Pro, Ala and Ser as well as one C-terminal arginine residue. MALDI spectra thus cover a mass range between 750 and 3200 m/z in MS mode and between 100 and 3200 m/z in MS/MS mode. Our results show that multipoint calibration of MS spectra using PAS-cal peptides compares well to current commercial reagents for protein identification by PMF. Calibration of tandem mass spectra from LC-MALDI experiments using the longest peptide, PAS-cal37, resulted in smaller fragment ion mass errors, more matching fragment ions and more protein and peptide identifications compared to commercial standards, making the PAS-cal standard generically useful for bottom-up proteomics.
Über die darstellung der d‐galakturonsäure durch enzymatischen pektinabbau (1948)

Abstract Es wird ein Verfahren zur Darstellung der d‐Galakturonsäure unmittelbar aus Pektin beschrieben. Der Abbau wird mit „Pectinol”︁, einem im Handel erhältlichen Filtrationsenzym, ohne Verwendung von Säuren oder Basen, beim Eigen‐p H des Pektins und bei 40°C durchgeführt. Zur Isolierung der Galakturonsäure wird aus den zum Sirup eingeengten Lösungen die Galakturonsäure mit Äthanol oder mit Methanol herausgelöst, wobei die Enzyme und die nicht vollständig hydrolysierten Pektine ausfallen. Es wurden Ausbeuten bis zu 71% der Theorie erreicht. Durch kinetische Messungen wurden die günstigsten Bedingungen für den Abbau ermittelt.

Synthesis of mitosenes from <i>N</i>‐aryl‐2‐(diphenylphosphinyl)pyrrolidines (1992)

Abstract A new route for the construction of the mitosene skeleton was developed using 2‐(diphenylphosphinyl)pyrrolidine (2) and 2‐methoxy‐3‐methyl‐1,4‐benzoquinone (3) as starting materials. Regioselective oxidative addition of 2 to 3 gave 5‐substituted pyrrolidinylbenzoquinone 4 . Protection of the quinone function by reduction, followed by in‐situ reaction with benzyl bromide, gave the bis‐benzylated product 5 . Using a recently developed route to pyrrolo[1,2‐a]indoles, 5 was converted into the protected mitosenes 8 . Debenzylation and subsequent oxidation of 8 produced the mitosenes 1 in good yields.

Treating Imatinib-Resistant Leukemia: The Next Generation Targeted Therapies (2006)

Imatinib (Gleevec/STI-571/CGP57148B, Novartis) is a small-molecule, tyrosine kinase inhibitor developed to target BCR-ABL, c-Kit, and PDGF-R. Through inhibition of these oncogenic kinases, imatinib is effective in the treatment of BCR-ABL-positive leukemia, gastrointestinal stromal tumor, and hypereosinophilic syndrome, respectively. However, clinical success of imatinib is hampered by acquired resistance that may occur through several mechanisms including kinase domain mutation, target amplification, and activation of alternate signaling pathways. Strategies to overcome resistance have included targeting BCR-ABL stability and downstream signaling pathways important for tumor growth. Additional work has shown that new BCR-ABL kinase inhibitors with increased potency or alternate conformation-binding properties can target imatinib resistance. This review focuses on the mechanisms of imatinib resistance and the strategies currently being developed to overcome clinical resistance.
Product Innovation for Interdisciplinary Design Under Changing Requirements (2007)

It is crucial for the development of high quality products that design requirements are identified and clarified as early as possible in the design process. In many projects the design requirements and design specifications evolve during the project cycle. Shifting needs of the customer, advancing technology, market considerations and even additional customers can cause the requirements to change. Because the different parts of a product are usually inter-connected, the requirements and specifications for one part of a product are often dependent on the requirements and the evolving design of other parts of the product. If uncontrolled, the design changes derived from evolving requirements may propagate through a design and disrupt the product development schedule, increase development costs, and result in a failure to satisfy the customers ’ needs. The challenge of designing with changing requirements can be even more challenging in a product development environment where a new product is targeted and/or with interdisciplinary teams. The work of this paper explores possible design strategies for product development under changing requirements. Six design strategies were identified and implemented in the development of an insect imaging device for the Bug ID project at Oregon State University. Based on experiences throughout this interdisciplinary project, this paper explores how to incorporate the considerations of evolving design requirements into feasible product development strategies.
Pollen Flow Within a Tristylous Species: Lythrum salicaria (1970)

Lythrum salicaria L. is a classic example of tristyly. Pollen flow within a natural population of this species was studied by analyzing pollen loads on stigmas of both intact and emasculated plants. The data obtained indicated that a significant amount of self pollination occurs within flowers but that between flowers or plants pollinations are predominantly legitimate, i.e. between stamens and styles of equal length. It is concluded that while the multiallelic system excels in reducing frequency of incompatible pollinations between plants, the heteromorphic system is relatively more effective in reducing self pollinations within a plant.
Nitrogen sources and net growth efficiency of zooplankton in three <scp>A</scp> mazon River plume food webs (2015)

The plasticity of nitrogen specific net growth efficiency (NGE) in marine mesozooplankton is currently unresolved, with discordant lines of evidence suggesting that NGE is constant, or that it varies with nitrogen source, food availability, and food quality in marine ecosystems. Specifically, the fate of nitrogen from nitrogen fixation is poorly known. We use 15 N : 14 N ratios in plankton in combination with hydrological data, nutrient profiles, and nitrogen fixation rate measurements to investigate the relationship between new nitrogen sources and the nitrogen specific NGE in three plankton communities along the outer Amazon River plume. The NGE of small (200-500 lm) mesozooplankton was estimated from the d 15 N differences between particulate nitrogen and zooplankton using an open system Rayleigh fractionation model. The transfer efficiency of nitrogen among larger (> 500 lm) mesozooplankton was estimated from the change in d 15 N as a function of zooplankton size. The Amazon River was not a significant source of bioavailable nitrogen anywhere in our study region, and subsurface nitrate was the primary new nitrogen source for the outer shelf community, which was dominated by diatoms. N 2 fixation was the principal new nitrogen source at sites of high diatom diazotroph association abundance and at oceanic sites dominated by Trichodesmium spp. and Synechococcus spp. Although we found clear spatial differences in food quantity, food quality, and diazotroph inputs into mesozooplankton, our data show no significant differences in mesozooplankton nitrogen transfer efficiency and NGE (for latter, mean 6 SD: 59 6 10%) among sites.
Frequency modulation detection interference produced by asynchronous and nonsimultaneous interferers (2000)

The effect of asynchronous and nonsimultaneous interferers on detection of sinusoidal frequency modulation (FM) was compared with the effect of a synchronous interferer. In a two-interval, two-alternative forced-choice (2I-2AFC) adaptive procedure, listeners had to detect FM with a modulation frequency of 15 Hz, imposed on a 1-kHz sinusoidal carrier (the target). The 200-ms target was presented either alone (baseline condition), or with an interferer whose timing relative to the target was varied. The interferer was a 2.3-kHz sinusoidal carrier which was also frequency modulated at a rate of 15 Hz. Experiment one showed that thresholds for detection of FM increased significantly, both with a synchronous FM interferer, and also with asynchronous interferers (starting 200 ms before and stopping 200 ms after the target). Moreover, "gapped" interferers that were turned off during presentation of the target (presented for 200 ms before and for 200 ms after the target but not simultaneously) produced the same significant increase in thresholds as an asynchronous interferer that was not interrupted. In contrast, thresholds were not affected by the presence of a gapped unmodulated sinusoidal interferer. Experiment two showed that increasing the duration of the silent gap (centered on presentation of the target) between FM interferers from 200 to 600 ms did not abolish the interference. Thus nonsimultaneous FM interferers produced frequency modulation detection interference (FMDI) even when the silent gap between the interferers and target clearly led to the interferers and target being perceived as separate auditory objects. A possible explanation for the findings is the existence of an asymmetry in perception of steady and modulated sounds, as recently proposed by Cusack and Carlyon [Br. J. Audiol. 34.2, 112 (2000)]. Alternative explanations in terms of ringing in a hypothetical modulation filter bank and adaptation seem unlikely.
Antibiotic resistance and plasmid profiling of Vibrio parahaemolyticus isolated from cockles in Padang, Indonesia (2009)

Vibrio parahaemolyticus is one of the most widely recognized pathogenic Vibrio species due to numerous outbreaks and its’ wide occurrence in marine environment. In this study, 32 isolates of V. parahaemolyticus isolated from cockles were tested for sensitivity to 16 antibiotics and the presence of plasmids. All the isolates were multi-resistance, defined as resistant to at least three different antibiotics with multiple antibiotic resistance indexes ranging from 0.31 to 0.69, indicating the isolates originate from high risk sources of contamination where antibiotics are often used. In the plasmid profiling test, only 15 isolates (47%) harbored plasmid DNA, which ranged in size from 2.7 to 56.2 kb, separating the isolates into 14 plasmid profiles. Hence, food contaminated with antibiotic resistant V. parahaemolyticus could be a major threat to public health due to the distinct possibility that they can be a significant reservoir of genes encoding antibiotic resistance determinants that can be transferred intra or interspecies. As in many developing countries, raw food hygiene and antimicrobial resistance epidemiology is still in the infancy stage in the locality of the study and thus our data provide a current baseline profile of antimicrobial resistance and plasmid of V. parahaemolyticus from cockles in Padang, Indonesia.
Dissecting Toxicity of Tau and β-Amyloid (2010)

Our data support the notion of a synergistic action of tau and Abeta pathology on mitochondria. A specific conformation of Abeta42 and human amylin determines toxicity. Finally, trapping of JIP1 by phosphorylated tau in the neuronal soma emerges as a fundamental pathomechanism in neurodegeneration.
Temperature Dependence of the Protein Resistance of Poly- and Oligo(ethylene glycol)-Terminated Alkanethiolate Monolayers (2001)

Fourier transform infrared reflection absorption spectroscopy (FT-IRRAS) has been used to study the protein resistance of poly- and oligo(ethylene glycol) (PEG and OEG) terminated alkanethiolate self-assembled monolayers (SAMs) on Au and Ag in the temperature range from 0 to 85 °C. These experiments extend previous room-temperature studies by Harder et al.1 who related the protein adsorption characteristics of OEG-SAMs to the lateral density and corresponding molecular conformation of the ethylene glycol (EG) moieties in the film. In addition to the short oligomer OEG-SAMs, we investigated PEG-derivatized alkanethiolate monolayers with an average chain length of 45 EG units and a mean molecular mass of 2000 g/mol (PEG2000). We observe that films, which are protein resistant at room temperature, maintain their protein repulsive characteristics up to 85 °C but may adsorb significant amounts of protein if the temperature is lowered.
Fast acquisition of quantitative T2 maps (1999)

A rapid new technique called T2 fast acquisition relaxation mapping (T2 FARM) was developed to allow T2 maps to be reconstructed directly from k-space data acquired in 3 sec. A single acquisition measured two sets of k-space data, the first with T1 and T2 weighting independent of phase encode position, and the second with T2 weighting varying with phase encode position. These data were processed using an iterative least squares algorithm to produce a quantitative T2 map from the k-space data. T2 values of phantoms and an egg were determined from T2 FARM maps and spectroscopic Carr-Purcell-Meiboom-Gill (CPMG) measurements, demonstrating the validity of the new technique.

Media access control development platform for wireless LANs (2003)

We introduce a Media Access Control (MAC) development platform for wireless LANs that (1) complements traditional simulation and analytical tools, and (2) provides a pioneering platform in academia based on the de-facto standard Windows operating system in addition to the legacy Unix environment. Our implementation includes two main modules (1) a wireless LAN network interface card (NIC) that includes only transmit/receive functionality and (2) a NIC device driver in which we have implemented a flexible plug-in module which allows us easy MAC protocol implementation. The proposed approach has the advantage that the testing of the protocol is performed in realistic environments, i.e., we use real traffic coming from off-the-shelf applications and a real wireless channel. We have implemented the proposed approach using Harris PRISM PC cards with the AMD PCnet microcontroller and Windows PCs. We introduce the implementation procedure and the performance results obtained from a wireless point-to-point experimental setup.

Abstract. In the last few years the e-Government discipline has attracted a growing attention both from practitioners and academics. Although the high number of action plan, projects and conferences spread all over Europe seems sanctioning the achievement of its maturitystage, several organizational and technological issues related with the modernization of service deliveryare still far from a comprehensive solution and still require significant efforts. In this paper, the approach followed and the results so far achieved within the Eu-Publi.com research project, are presented. The discussion on the conceptual and design architectures of the Eu-Publi.com distributed, peer-to-peer system is enriched with results about the experimentation conducted on one of its core components. 1
Will superconducting magnetic energy storage be used on electric utility systems? (1975)

As the cost of fossil fuel has increased and the load factors on electric utilities have decreased, the need for efficient, reliable energy storage systems has increased. Although pumped hydro storage is now used extensively on those utility systems having the appropriate resources nearby, it is only 65% efficient. Superconducting magnetic energy storage which promises to be more than 90% efficient and easily sited may become a competitive energy storage technology. A comparison of the various energy storage systems is presented in terms of performance on electric power systems, and cost. Emphasis is given to the various technologies involved in the development of large superconducting magnets. A brief review of the Los Alamos Scientific Laboratory program on superconducting magnetic energy storage is included.
Sparse Cellular Neugebauer Model for N-ink Printers (2006)

The number of colorants used in printers is growing to improve quality of the prints in terms of gamut size, grain and metamerism. In this paper we demonstrate a modification to the existing models (Cellular Neugebauer Model, with Yule Nielson Correction) to simulate spectral reflectance of an N-ink printer. This is achieved by imposing a constraint for the media ink limit, the modified model is shown to reduce the required number of training points by as much as 97 percent. Imposing this constraint leaves us with sparse training data set and the modified Yule-Nielson Neugebauer Spectral model is shown to handle the sparse data well with average error of 1.48 ΔE94.In this paper, two standard dot placement models (Dot-on-dot v.s. Demichel) are implemented and compared.
The Solubility of Phenanthrene in Toluene: In-situ ATR-FTIR, Experimental Measurement, and Thermodynamic Modelling (2008)

A comprehensive study of the solubility of phenanthrene in toluene as a model system to investigate the supercritical gas anti-solvent crystallization process is performed over a wide range of temperatures. The applicability of in-situ ATR-FTIR measurements for an improved understanding of the dynamics of the concentration profile of the dissolved compound in the liquid solvent is studied. Experimental determination of the solubility of phenanthrene in toluene was also achieved employing a gravimetric technique over the temperatures range 25 to 65°C. Excellent predictions of the solubility measurements were achieved using Regular Solution Theory and the Flory-Huggins Correction. Furthermore, this work demonstrated that in-situ ATR-FTIR is a valuable technique for monitoring and control of crystallization processes. On a réalisé pour une vaste gamme de températures une étude complète de la solubilité du phénanthrène dans le toluène utilisé comme système modèle pour étudier le procédé de cristallisation d'anti-solvant de gaz superficielle. On étudie l'applicabilité de mesures ATR-FTIR in situ pour mieux comprendre la dynamique du profil de concentration du composant dissous dans le solvant liquide. La détermination expérimentale de la solubilité du phénanthrène dans le toluène s'est également effectuée par une technique gravimétrique dans une gamme de températures comprises entre 25 et 65 °C. D'excellentes prédictions des mesures de solubilité ont été réalisées avec la théorie des solutions régulière et la correction de Flory-Huggins. En outre, on démontre dans ce travail que l'ATR-FTIR in situ est une technique valable pour la surveillance et le contrôle des procédés de cristallisation.
