Gain dependent self-phasing in a two-core coherently combined fiber laser (2018)

The influence of the Kramers-Kronig phase is demonstrated in a coherently combined fiber laser where other passive phasing mechanisms such as wavelength tuning have been suppressed. A mathematical model is developed to predict the lasing supermode and is supported by experimental measurements of the gain, phase, and power. The results show that the difference in Kramers-Kronig phase arising from a difference in gain between the two arms partially compensates for an externally applied phase error.
Cathodoluminescence Contrast of Localized Defects Part I. Numerical Model for Simulation (1995)

A three-dimensional model has been developed for cathodoluminescence contrast of localized defects in semiconductors. The numerical model incorporates electron-solid interaction effects, charge transport phenomena and optical losses. Electron-solid interaction is modelled by a Monte Carlo method. Three-dimensional continuity equation and derivative boundary conditions are discretized by a central-difference quotients scheme. Localized defects are represented by regions of enhanced non-radiative recombination. The discretized linear difference equations of the boundary value problem are solved by the successive-over-relaxation method. A method for avoiding the divergence problem during the successive-over-relaxation calculation is illustrated. The solutions of the model are compared with the analytical results of several established models.
Photoinduced hyper-reflective cholesteric liquid crystals enabled via surface initiated photopolymerization (2010)

A structured polymer was synthesized by surface initiated photopolymerization in the presence of a cholesteric liquid crystal (CLC). The templated helical polymer (traversing 2/3 the cell thickness) was backfilled with an opposite handedness, photoresponsive CLC mixture yielding a photo-induced, large contrast, hyper-reflective (R > 99%) CLC film.
Introduction to special section: Fractures (2015)

Understanding the spatial distribution of natural fractures (orientation and magnitude) is important for drilling and producing from hydrocarbon reservoirs. In unconventional reservoirs (e.g., shale gas, shale oil, tight gas), natural fractures are the only pathways for fluid flow. If there are not

Understanding the Hydrodenitrogenation of Heteroaromatics on a Molecular Level (2016)

The cleavage of recalcitrant C–N linkages in heteroaromatic molecules is a critical component of hydrodenitrogenation (HDN) reactions, the processes by which N atoms are removed from crude fuels. C–N bond cleavage of heteroaromatics with traditional HDN catalysts such as sulfided Ni/Mo-Al2O3 and Ni/W-Al2O3 requires aggressive conditions to hydrogenate the heterocyclic rings and often unnecessarily saturates the carbocyclic rings as part of the C–N cleavage process. In contrast, small-molecule models have illustrated selective hydrogenation of the heterocyclic ring, providing mechanistic insight into HDN processes and inspiring the design of new, more selective HDN catalysts.
High Contrast and Fast Response Polarization-Independent Reflective Display Using a Dye-Doped Dual-Frequency Liquid Crystal Gel (2006)

We have developed a new guest-host reflective display using a dye-doped dual-frequency liquid crystal (DFLC) gel. By combining dye absorption and maximal light scattering, the display is polarization independent and exhibits a high contrast (∼ 230:1). The high reflectivity (R ∼ 50%) is because of the vertical aligned structure at 0 Vrms. The fast response time (∼ 5 ms) is also fast due to the frequency modulation. A black and white segmented-alphabet reflective display prototype is also demonstrated.

Multi-stream sum-rate-maximizing interference alignment under sparsity constraints (2013)

We study the problem of per-stream joint maximum sum-rate (MSR) precoder and minimum mean-squared error (MMSE) equalizer design for interference alignment in the multi-input multi-output interference channel. We consider the general case of more than three users with more than one stream per user. We propose a new generalized iterative algorithm which directly maximizes the average overall sum-rate without assuming the signal-to-noise ratio to be infinite. The receivers' implementation complexity increases proportional to the square of the number of equalizer taps which becomes prohibitive as the network size increases. To address this issue, we examine the performance-complexity tradeoffs involved in a sparse equalizer design. Our numerical results demonstrate that, for the full-complexity MMSE equalizer design, our proposed algorithm achieves higher overall sum-rate compared to previously proposed interference alignment algorithms. In addition, we reduce the MMSE linear equalizer complexity by 30% while limiting the sum-rate loss to about 10%, at most, compared to the full-complexity design.
AI Enabled Processing of Environmental Sounds in Commercial and Defense Environments (2022)

Ambient sounds provide a wealth of information which can be useful in many IoT solutions in commercial and defense use cases. The application of AI based techniques to traditional acoustic signal processing can provide many interesting use cases which include a diverse set such as detecting faults in industrial manufacturing, identifying possible illnesses in chicken farms, efficient process management of naval facility equipment, and detecting possible intruders at borders. The use of AI provides an augmented capability for a data driven understanding of the environment, but also comes with several challenges. AI models need to operate in environments which may be different from the environment within which they are trained. Effective use of AI models in acoustics requires technologies that can enable these models to retrain themselves, or adapt themselves dynamically within the deployed environment. In this chapter, a system for deploying AI based acoustic models in real-world environments, and lessons learned from them is described.

A novel crossed microfluidic device for the precise positioning of proteins and vesicles (2005)

Herein we present a novel way to create arrays of different proteins or lipid vesicles using a crossed microfluidic device. The concept relies on the combination of I) a designated two-step surface chemistry, which allows activation for subsequent binding events, and II) crossing microfluidic channels for the local functionalization by separated laminar streams. Besides its simplicity and cost efficiency, this concept has the advantage that it keeps the proteins in a hydrated environment throughout the experiment. We have demonstrated the feasibility of such a device to create a chessboard pattern of different fluorescently labeled lipid vesicles, which offers the possibility to contain biomolecules, drugs or membrane proteins.
Fusionierte Bildgebung mit PET/CT bei Lungenrundherden: Einfluss auf das Staging des Bronchialkarzinoms (2005)

Ziele: In dieser prospektiven Studie wurden Patienten mit Erstdiagnose eines Bronchialkarzinoms oder suspekten pulmonalen Rundherden mit FDG-PET/CT untersucht und die klinische Wertigkeit der fusionierten Bildgebung hinsichtlich Dignitätsbeurteilung und TNM-Staging evaluiert. Methode: Bislang wurden 128 Patienten (Pat.) mit histologisch gesichertem Bronchialkarzinom oder neu diagnostiziertem Lungenrundherd in diese prospektive Studie eingeschlossen. PET/CT wurde bei allen Pat. mit einem modernen Hybrid-Scanner (GE Discovery LS) durchgeführt. 60min nach i.v.-Injektion von 370 MBq F-18-FDG erfolgte zunächst eine Spiral-CT mit Kontrastmittel von cervikal bis inguinal. CT, PET und die PET/CT-Bildfusion wurden für das TNM-Staging verwendet. Als Referenzmethode diente der histologische Befund im resezierten Tumorgewebe bzw. in der Biopsie. Bei Kontraindikation zur Operation wurden sämtliche vorliegenden bildgebenden Verfahren und der klinische Verlauf als Referenz verwendet. Ergebnis: Die Histologie ergab bei 99 Pat. einen malignen Lungentumor. Hinsichtlich der Detektion maligner Tumore ergab sich eine Sensitivität der PET/CT von 99% (98/99), eine Spezifität von 75% (21/28) und eine Treffsicherheit von 94%. Bez. des Lymphknotenstatus wurden 33 Pat. mit PET/CT als negativ beurteilt (N0), 8 Pat. als N1 und 10 Pat. als N2. Für die Differenzierung N0 gegenüber N1/N2 ergab sich eine Sensitivität der PET/CT von 78% (14/18), eine Spezifität von 94% (33/38) und eine Treffsicherheit von 86%. 24 Pat. wurden als inoperabel (N3-Situation) eingestuft, bei 44 Pat. waren zusätzlich hämatogene Fernmetastasen nachweisbar (M1). Die Treffsicherheit der PET/CT zur Unterscheidung operabler (N1, N2, M0) und inoperabler Patienten (N3, M1) beträgt 94% (Sensitivität 91% (50/55), Spezifität 100% (44/44)). Schlussfolgerung: Die fusionierte Bildgebung mit PET/CT ermöglicht eine hohe Treffsicherheit für die Dignitätsbeurteilung suspekter Lungenrundherde und für die Differenzierung operabler (N0, N1, N2) und inoperabler Patienten (N3, M1).
Techno-economic viability of energy storage concepts combined with a residential solar photovoltaic system: A case study from Finland (2021)

Solar photovoltaic systems have been growing in popularity in prosumer households as a means of increasing the share of renewable energy and decreasing electricity import. The available self-consumption is, however, limited by a temporal supply–demand imbalance. In this paper, options for improving the self-consumption of a prosumer household are studied by using three-year data sets of electricity import and export data from two distinct, real-life cases from Finland. Two separate approaches are analysed: the use of energy storages, physical or monetary, and changing of the electricity metering method. A switch of the electricity metering method from instant phasewise to hourly net metering was found to increase the self-sufficiency by about 3 to 5 percentage points and have an annual monetary benefit of a few tens of euros when a network storage was used. Considering the energy storage methods under study, the network energy storage was found to be more economically feasible than a physical or a virtual battery energy storage, even though a physical battery storage could increase the self-sufficiency as much as by 30 percentage points with a storage capacity of 20 kWh. The studied virtual battery concept was found to limit the profitable solar photovoltaic plant size if high enough storage capacity was not provided. When a physical battery energy storage is used, switching to hourly net metering does not add value to the system. A significant decrease in the system cost is required for a physical battery energy storage to be economically competitive in northern climate conditions.
Evaluation of 25-cm XIPS © Thruster Life for Deep Space Mission Applications (2009)

The 25-cm Xenon Ion Propulsion System (XIPS © ) thruster has been used for station keeping on Boeing 702 class satellites for nearly 10 years now, and 68 of these thrusters are operating in orbit on 17 spacecraft at this time. The 25-cm life-test thruster also successfully completed a 16,250 hour life test with 14,134 On-Off cycles distributed over two power levels with a total throughput of about 170 kg. This life performance satisfies Boeing's station keeping application requirements with adequate margin. However, prime- propulsion applications for deep space missions typically require significantly longer thruster operating times and higher throughput levels. A joint program at Jet Propulsion Laboratory (JPL) and L-3 Communications, Inc. has undertaken an evaluation of the life of the thruster for these applications. The primary wear locations in the ion thruster are the discharge and neutralizer cathodes and the high voltage grids. A 25-cm flight discharge cathode assembly successfully completed a 16,000 hour wear test at JPL at three different current levels and the data used to benchmark JPL's cathode life code predictions. The performance of a 25cm neutralizer cathode was investigated to determine the mechanisms responsible for the observed erosion in the thruster life test, and a wear test of a modified version of this cathode is underway to aid in demonstrating the desired life. Extensive modeling of the XIPS thruster grid wear has been performed using an upgraded version of JPL's CEX-2D code to determine the throughput capabilities of the thruster based on grid life. The CEX code has been benchmarked against the NSTAR LDT and ELT life tests and the observed accel-grid erosion in the 25-cm XIPS life test. The code predicts that the XIPS grid life significantly exceeds the NSTAR thruster grid life because of a higher accel voltage capability of the XIPS power supply, the third grid in the ion optics assembly which eliminates pits-and-grooves erosion of the downstream accel grid, and a flatter beam profile compared to NSTAR that reduces the peak current density on axis at a given power level. Evaluations of the grid life indicate that the XIPS thruster will process over 200 kg of xenon propellant with 50% margin, and even higher throughputs are possible for mission trajectories that have a large fraction of the thrusting time at low power levels.
Interleukin 2 counteracts the inhibition of cytotoxic T lymphocytes by cholera toxin in vitro and in vivo (1991)

Cholera toxin irreversibly activates a 43-kDa guanosine triphosphate (GTP)-binding protein by adenosine diphosphate ribosylation, resulting in activation of adenylate cyclase and increased intracellular levels of cyclic adenosine monophosphate (cAMP). Because increases in intracellular cAMP inhibit interleukin 2 (IL 2) expression and cytotoxic T lymphocyte (CTL) generation and function in vitro and in vivo, we hypothesized that IL 2 may counteract the inhibition of CTL by cholera toxin. Activated CTL treated with IL 2 were protected from the inhibitory effects of cholera toxin. IL 2 also counteracted the inhibitory effect of cholera toxin on steady-state levels of CTL-specific serine esterase mRNA. Given the putative role of serine esterase for in vitro generated CTL effector activity, these results may account for recovery of CTL activity. Although IL 2 restored CTL function and serine esterase transcription, it did not block cholera toxin-catalyzed ribosylation of the 43-kDa GTP-binding protein, nor did it prevent the accumulation of intracellular levels of cAMP. In vivo, C57BL/6 mice challenged with the allogeneic tumor P815 had suppressed CTL function when cholera toxin was administered. These cholera toxin-treated mice died of tumor overgrowth, whereas untreated mice rejected the allogeneic tumor. Co-treatment of alloimmunized mice with cholera toxin and IL 2 prevented death from tumor overgrowth and restored CTL function; 67% of these mice survived. These data provide evidence that IL 2 acts in CTL through a mechanism independent of cholera toxin-sensitive GTP-binding protein in vitro and in vivo, despite elevated intracellular cAMP levels.

Highly Efficient Cadmium-Free Quantum Dot Light-Emitting Diodes Enabled by the Direct Formation of Excitons within InP@ZnSeS Quantum Dots (2013)

We demonstrate bright, efficient, and environmentally benign InP quantum dot (QD)-based light-emitting diodes (QLEDs) through the direct charge carrier injection into QDs and the efficient radiative exciton recombination within QDs. The direct exciton formation within QDs is facilitated by an adoption of a solution-processed, thin conjugated polyelectrolyte layer, which reduces the electron injection barrier between cathode and QDs via vacuum level shift and promotes the charge carrier balance within QDs. The efficient radiative recombination of these excitons is enabled in structurally engineered InP@ZnSeS heterostructured QDs, in which excitons in the InP domain are effectively passivated by thick ZnSeS composition-gradient shells. The resulting QLEDs record 3.46% of external quantum efficiency and 3900 cd m(-2) of maximum brightness, which represent 10-fold increase in device efficiency and 5-fold increase in brightness compared with previous reports. We believe that such a comprehensive scheme in designing device architecture and the structural formulation of QDs provides a reasonable guideline for practical realization of environmentally benign, high-performance QLEDs in the future.
Stable efficiency roll-off in phosphorescent organic light-emitting diodes (2008)

Origin of efficiency roll-off in phosphorescent organic light-emitting diodes was investigated with triplet mixed host devices and stable devices with little efficiency roll-off was developed. Efficiency roll-off was significant in the device with narrow recombination zone (RZ) and charge leakage out of emitting layer at high luminance was critical to efficiency roll-off. Efficiency roll-off could be reduced in triplet mixed host device with broad RZ and little charge leakage at high driving voltage. Triplet mixed host devices with an exciton blocking layer showed a quantum efficiency over 90% of maximum quantum efficiency at a luminance of 20000cd∕m2.
Printability of nonsmoothed buried defects in extreme ultraviolet lithography mask blanks (2005)

One of the most important challenges in extreme ultraviolet lithography is the need to provide mask blanks free of defects. In order to provide experimental results on the printability of buried defects, a dedicated extreme ultraviolet (EUV) mask blank was manufactured using ion beam sputtering (IBS) with a nonsmoothing process. Using this kind of process, the effect of the buried defect is apparent throughout the entire multilayer stack. The disturbance generated in the multilayer, measured using an atomic force microscope (AFM), shows lateral growth and a slight vertical smoothing effect. Here we report the printability results obtained with this kind of defect. One result concerns the influence of the defect density on the printability. We show that the major effect can be attributed to local flare, which depends on the pattern density. In order to better understand the printability mechanism of this kind of buried defect, we also compared the experimental results with electromagnetic simulation.
Proton Electroreduction Catalyzed by Cobaloximes:  Functional Models for Hydrogenases (2005)

Cobaloximes have been examined as electrocatalysts for proton reduction in nonaqueous solvent in the presence of triethylammonium chloride. [Co(III)(dmgH)2pyCl], working at moderate potentials (-0.90 V/(Ag/AgCl/3 mol x L(-1) NaCl) and in neutral conditions, is a promising catalyst as compared to other first-row transition metal complexes which generally function at more negative potentials and/or at lower pH. More than 100 turnovers can be achieved during controlled-potential electrolysis without detectable degradation of the catalyst. Cyclic voltammograms simulation is consistent with a heterolytic catalytic mechanism and allowed us to extract related kinetic parameters. Introduction of an electron-donating (electron-withdrawing) substituent in the axial pyridine ligand significantly increases (decreases) the rate constant of the catalytic cycle determining step. This effect linearly correlates with the Hammet coefficients of the introduced substituents. The influence of the equatorial glyoxime ligand was also investigated and the capability of the stabilized BF2-bridged species [Co(dmgBF2)2(OH2)2] for electrocatalyzed hydrogen evolution confirmed.
