Rigid vibrations of a photonic crystal and induced interband transitions (2000)

We investigate the behavior of electromagnetic states associated with photonic crystals, which are undergoing rigid time-dependent translations in position space. It is shown, quite generally, that the Bloch wave vector q remains a conserved quantity and that an analogue of Bloch's theorem for a time-dependent solution of the states can be formulated. Special attention is focussed on time-dependent translations involving harmonic rigid vibrations of the photonic crystal. Under these conditions it is shown how, and to what extent, inter-band transitions can be induced between the various bands in a photonic crystal in a microwave regime. In particular, a characteristic resonance transition time can be derived, which scales inversely with the amplitude of vibration and interband frequency. Finally, it is argued that given all parameters other than Bloch wave vector fixed, an interband transition time is minimized if the transition is made at a Bragg plane.

Statistical model selection methods applied to biological networks (2005)

Abstract. Many biological networks have been labelled scale-free as their degree distribution can be approximately described by a powerlaw distribution. While the degree distribution does not summarize all aspects of a network it has often been suggested that its functional form contains important clues as to underlying evolutionary processes that have shaped the network. Generally determining the appropriate functional form for the degree distribution has been fitted in an ad-hoc fashion. Here we apply formal statistical model selection methods to determine which functional form best describes degree distributions of protein interaction and metabolic networks. We interpret the degree distribution as belonging to a class of probability models and determine which of these models provides the best description for the empirical data using maximum likelihood inference, composite likelihood methods, the Akaike information criterion and goodness-of-fit tests. The whole data is used in order to determine the parameter that best explains the data under a given model (e.g. scale-free or random graph). As we will show, present protein interaction and metabolic network data from different organisms suggests that simple scale-free models do not provide an adequate description of real network data. 1
Accurate determination of production data of the non-standard positron emitter 86Y via the 86Sr(p,n)-reaction (2020)

Abstract In view of several significant discrepancies in the excitation function of the 86 Sr(p,n) 86g+xm Y reaction which is the method of choice for the production of the non-standard positron emitter 86 Y for theranostic application, we carried out a careful measurement of the cross sections of this reaction from its threshold up to 16.2 MeV at Forschungszentrum Jülich (FZJ) and from 14.3 to 24.5 MeV at LBNL. Thin samples of 96.4% enriched 86 SrCO 3 were prepared by sedimentation and, after irradiation with protons in a stacked-form, the induced radioactivity was measured by high-resolution γ -ray spectrometry. The projectile flux was determined by using the monitor reactions nat Cu(p,xn) 62,63,65 Zn and nat Ti(p,x) 48 V, and the calculated proton energy for each sample was verified by considering the ratios of two reaction products of different thresholds. The experimental cross section data obtained agreed well with the results of a nuclear model calculation based on the code TALYS. From the cross section data, the integral yield of 86 Y was calculated. Over the optimum production energy range E p = 14 → 7 MeV the yield of 86 Y amounts to 291 MBq/μA for 1 h irradiation time. This value is appreciably lower than the previous literature values calculated from measured and evaluated excitation functions. It is, however, more compatible with the experimental yields of 86 Y obtained in clinical scale production runs. The levels of the isotopic impurities 87m Y, 87g Y, and 88 Y were also estimated and found to be &lt;2% in sum.

Pharmaceutical Product Quality (2018)

Because of the high doses employed - which can exceed 100 g of substance per patient and examination – very high demands are made on CM in terms of chemical purity. The molecular structure of the CM substance is confirmed by NMR (nuclear magnetic resonance),, IR (infra red), MS (mass spectrometry) and UV (ultraviolet) spectra (fig. 13a-e).
Ensembles of Generative Adversarial Networks for Disconnected Data (2020)

Most current computer vision datasets are composed of disconnected sets, such as images from different classes. We prove that distributions of this type of data cannot be represented with a continuous generative network without error. They can be represented in two ways: With an ensemble of networks or with a single network with truncated latent space. We show that ensembles are more desirable than truncated distributions in practice. We construct a regularized optimization problem that establishes the relationship between a single continuous GAN, an ensemble of GANs, conditional GANs, and Gaussian Mixture GANs. This regularization can be computed efficiently, and we show empirically that our framework has a performance sweet spot which can be found with hyperparameter tuning. This ensemble framework allows better performance than a single continuous GAN or cGAN while maintaining fewer total parameters.

Polyfunctional anti-human epidermal growth factor receptor 3 (anti-HER3) antibodies induced by HER3 vaccines have multiple mechanisms of antitumor activity against therapy resistant and triple negative breast cancers (2018)

In addition to the T cell anti-tumor response induced by Ad-HER3, the HER3-VIAs provide additional functions to eliminate tumors in which HER3 signaling mediates aggressive behavior or acquired resistance to HER2-targeted therapy. These data support clinical studies of vaccination against HER3 prior to or concomitantly with other therapies to prevent outgrowth of therapy-resistant HER2+ and triple negative clones.
Ultrahigh resolution OCT using continuum generation in an air-silica microstructure optical fiber (2000)

We demonstrate ultrahigh-resolution optical coherence tomography using continuum generation in an air-silica microstructure fiber. Using bandwidths near 1.3 µm, longitudinal resolutions of 4.0 µm are achieved. This is the highest resolution imaging performed in this wavelength range and the first demonstration of this new technology for OCT.
Enzymatic Cyclization Involving Intramolecular Michael Addition by Catalase: Formation of 2-Methylbenzimidazoles (1990)

Our interest in the use of enzymes as biocatalysts for heterocyclic synthesis by intramolecular cyclizations exhibited interesting findings.'"Recently, we described3 the catalase-mediated cycliration of 1-allyl-3-(0-cyanopheny1)urea and o-cyanophenyl allylcarbamate.In the programme directed to explore the potential of enzymes in organic synthesis, various enzymes such as catalase, lipases and as well enzymes obtained from different sources such as liver microsomes and yeasts, were investigated for cyclization.Catalase has been widely used for the hydroperoxide-dependent N-dealkylation of a number of aromatic secondary and tertiary amines.Herein, we wish to report the novel use of catalase for the cyclization involving intramolecular 5 Michael addition of ethyl 4-2-aminoanilinocrotonates (h-c) to 2-methylbenzimidazoles (2-5).
Myosin filaments in cytoskeletons of Dictyostelium amoebae (1987)

Cytoskeletons were prepared from vegetative amoebae of Dictyostelium discoideum by extraction with Triton X-100. The cytoskeletons were suspended in buffers known to induce the assembly or disassembly of myosin filaments. The samples were fixed, and thin sections were examined by transmission electron microscopy. In both types of buffers, myosin-containing cytoskeletons exhibited a ring of densely staining proteinaceous material within the cortical filament matrix; this ring was not observed in myosin-free cytoskeletons. When myosin-containing cytoskeletons were placed in buffers that induced myosin polymerization, the ring appeared as an array of rodlike filaments approximately 13 nm wide and up to 0.5 micron in length--dimensions appropriate for myosin thick filaments. If ATP was added to cytoskeletons containing such filaments, the cytoskeletons contracted and the ring of filaments disappeared. ATP-induced contraction of cytoskeletons was also visualized by indirect immunofluorescence by using monoclonal antibodies to Dictyostelium myosin. All data were consistent with the identification of the protein ring seen by electron microscopy as cortical myosin. Its location and organization were appropriate for the production of cortical contraction through a sliding filament mechanism.
Phase controller outperforms impedance controller for a hip exoskeleton (2020)

Developing controllers for exoskeletons has many challenging requirements: one of which is creating a torque command based on measured human data that that is in phase with the user (in-synchrony with the human gait). We show that the hip torque for walking gait can be modeled using a phase angle based on hip angular position and velocity. This model is superior to a standard impedance model based on inertia, damping, and stiffness parameters because the phase model uses less parameters and they change linearly with varying speed and weight. The controller has been tested on ten subjects (weighing from 68 to 118kg) wearing the hip exoskeleton walking at speeds from 0.7 to 1.8m/s in outdoor environments.
Alpha 1‐Antitrypsin and Ilomastat Inhibit Inflammatory Proteases Present in Human Middle Ear Effusions (2003)

Proteases are commonly found in OM. Ilomastat and rAAT are potent inhibitors of proteases in MEEs across a wide range of OM in humans. Investigation into the potential therapeutic benefits of these protease inhibitors is warranted.
Mooring Component Perormance Kevlar Mooring Lines (1978)

Kevlar <sup xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">®</sup> ropes used as oceanographic mooring lines potentially offer the advantages of corrosion resistance, low stretch combined with high strength and low specific gravity. Tests completed at sea to date on a variety of line constructions to evaluate the performance of the material in the ocean environment, have resulted in ambiguous but disappointing results. Strength degradations have been noted that reduce its desirability as a long term mooring line material. More testing must therefore be completed to determine the reasons for the noted strength reductions so that methods or eliminating the problem may be found.
Molecular and Antibiofilm Approaches to Prosthetic Joint Infection (2003)

The majority of patients with prosthetic joint replacement (arthroplasty) experience dramatic relief of pain and restoration of satisfactory joint function. In the United States, more than.5 million people have a primary arthroplasty each year. Less than 10% of prosthesis recipients have complications develop during their lifetime, commonly as a result of aseptic biomechanical failure, followed by prosthetic joint infection. The pathogenesis of prosthetic joint infection is related to bacteria in biofilms, in which they are protected from antimicrobial killing and host responses rendering these infections difficult to eradicate. Current microbiology laboratory methods for diagnosis of prosthetic joint infection depend on isolation of a pathogen by culture. However, these methods have neither ideal sensitivity nor ideal specificity. Therefore, culture-independent molecular methods have been used to improve the diagnosis of prosthetic joint infection. In the research setting, detection of 16S ribosomal deoxyribonucleic acid by polymerase chain reaction has been used in the molecular diagnosis of prosthetic joint infection. Various antibiofilm strategies directed at disruption of adherent bacteria are the focus of intense research to improve the detection of biofilm organisms and their eradication. In this article, molecular and antibiofilm approaches to prosthetic joint infection are reviewed.
Volumetric breast density measurement for personalized screening: accuracy, reproducibility, and agreement with visual assessment (2018)

Assessment of breast density at the point of mammographic examination could lead to optimized breast cancer screening pathways. The onsite breast density information may offer guidance when to recommend supplemental imaging for women in a screening program. In this work, performance evaluation of a new software (Insight BD, Siemens Healthcare GmbH) for fast onsite quantification of volumetric breast density is presented. Accuracy of volumetric measurement is evaluated using breast tissue equivalent phantom experiments. Reproducibility of measurement results is analyzed using 8150 4-view mammography exams. Furthermore, agreement between breast density categories computed by the software with those determined visually by radiologists is examined. The results of the performance evaluation demonstrate that the software delivers accurate and reproducible measurements that agree well with the visual assessment of breast density by radiologists.

Application Master Session Key (AMSK) for Mobile IPv6 (2006)

The Extensible Authentication Protocol (EAP) defines an extensible
framework for performing network access authentication. Most EAP
authentication algorithms, also known as methods, export keying
material that can be used with lower layer ciphersuites. It can be
useful to leverage this keying material to derive usage specific keys
that can be used to authenticate users or protect information exchange
by other applications or services.For this purpose [10] proposes to
derive root keys for each usage application and, then, child keys to
actual be used. This document defines how to generate a Usage Specific
Root Key (USRK) and a series of Application Master Session Keys
(AMSKs) specific to Mobile IPv6 service. These AMSKs can be used by
Mobile Node and Home Agent to bootstrap Mobile IPv6 protocol
operation. This document defines how to generate Application Master

All-optical modulation using an n-doped quantum-well structure (1990)

The modulation of interband-resonant light by intersubband-resonant light using an n-doped quantum well is proposed, and results of the theoretical analysis are reported. It is shown that a large change in absorption coefficient from 100 to 3160 cm−1 for interband-resonant light can be obtained by changing the intensity of intersubband-resonant light from 0 to 1 MW/cm2. Very fast modulation speed (∼ps) can be expected.
Functional Requirements to Exceed the 100 kW/l Milestone for High Power Density Automotive Diesel Engines (2017)

&lt;div class="section abstract"&gt;&lt;div class="htmlview paragraph"&gt;The paper describes the challenges and results achieved in developing a new high-speed Diesel combustion system capable of exceeding the imaginative threshold of 100 kW/l. High-performance, state-of-art prototype components from automotive diesel technology were provided in order to set-up a single-cylinder research engine demonstrator.&lt;/div&gt;&lt;div class="htmlview paragraph"&gt;Key design parameters were identified in terms boost, engine speed, fuel injection pressure and injector nozzle flow rates. In this regard, an advanced piezo injection system capable of 3000 bar of maximum injection pressure was selected, coupled to a robust base engine featuring ω-shaped combustion bowl and low swirl intake ports.&lt;/div&gt;&lt;div class="htmlview paragraph"&gt;The matching among the above-described elements has been thoroughly examined and experimentally parameterized. The tests confirmed the benefits of the employment of very high fuel injection pressures as a way to decouple the trade-off between an excellent power rating and emissions / NVH / CO&lt;sub&gt;2&lt;/sub&gt; at part load, whose combination truly defines the leading edge of modern diesel engines for automotive application.&lt;/div&gt;&lt;div class="htmlview paragraph"&gt;The paper also discusses the system sensitivity to the boundary conditions, of the charging and exhaust systems, and develops a balanced set of targets for the entire system based on thermo-structural, fluid-dynamics and efficiency considerations. This would represent, in the authors' view, the 'recipe' for the next generation of premium diesel engines for automotive application.&lt;/div&gt;&lt;/div&gt;
Predicting concept types in user corrections in dialog (2009)

Most dialog systems explicitly confirm user-provided task-relevant concepts. User responses to these system confirmations (e.g. corrections, topic changes) may be misrecognized because they contain unrequested task-related concepts. In this paper, we propose a concept-specific language model adaptation strategy where the language model (LM) is adapted to the concept type(s) actually present in the user's post-confirmation utterance. We evaluate concept type classification and LM adaptation for post-confirmation utterances in the Let's Go! dialog system. We achieve 93% accuracy on concept type classification using acoustic, lexical and dialog history features. We also show that the use of concept type classification for LM adaptation can lead to improvements in speech recognition performance.
Damping Pressure Pulsations in a Wave-Powered Desalination System (2014)

Wave-driven reverse osmosis desalination systems can be a cost-effective option for providing a safe and reliable source of drinking water for large coastal communities. Such systems usually require the stabilization of pulsating pressures for desalination purposes. The key challenge is to convert a fluctuating pressure flow into a constant pressure flow. To address this task, stub-filters, accumulators, and radially elastic-pipes are considered for smoothing the pressure fluctuations in the flow. An analytical model for fluidic capacitance of accumulators and elastic pipes are derived and verified. Commercially available accumulators in combination with essentially rigid (and low cost) piping are found to be a cost-effective solution for this application, and a model for selecting accumulators with the required fluidic-capacitance for the intended system is thus presented.
Scintillation and dosimetric properties of Eu-doped SrCO<sub>3</sub> ceramics prepared by spark plasma sintering method (2016)

Eu-doped SrCO3 (Eu:SrCO3) ceramics are prepared by a spark plasma sintering (SPS) technique. In photoluminescence (PL), emissions around 615 nm due to 4f–4f transition of Eu3+ appear under several excitation wavelengths. The PL decay time constants are 314 ns due to the host and 400–600 µs due to Eu3+. The X-ray induced scintillation spectra show an intense emission peak and some small bands around 615 nm and scintillation decay time constants are 210–224 µs. In thermally stimulated luminescence (TSL) after X-ray irradiation, a strong TSL glow peak is observed in 450°C and TSL intensity increase in association with Eu concentration.
