Development of a computational tool for simulating inductive superconducting fault current limiters (2015)

In order to adopt superconducting fault current limiters, as other technologies, electric utilities require computational tools that can be employed in simulating these devices in complex grids under different conditions, in the present case. This paper describes such tool, focusing on inductive superconducting fault current limiters of magnetic shielding type. The tool is implemented in Simulink, due to its wide application, and can easily be extended to other software packages.
Multiple interrogation of phase-conjugating arrays (2009)

The performance of a phase-conjugating array (PCA) in a multiple-interrogator environment is investigated. The PCA demonstrates the ability to properly retrodirect signals toward multiple interrogators to varying degrees, dependent on phase, angle of incidence, and amplitude differences between the interrogators. The effect of the three parameters is demonstrated for the 6-GHz array at interrogating angles of plusmn10deg and plusmn20deg. Agreement between the experimental results and theoretical simulations confirm the validity of the measurements; extrapolation of the simulations for additional cases is also presented.
Sera from patients with active systemic lupus erythematosus patients enhance the toll-like receptor 4 response in monocyte subsets (2015)

Our data suggest that SLE sera induce an abnormal in vitro TLR4 response in classical and non-classical monocytes, reflected by a higher TNF-α intracellular expression. These effects may be operative in the pathogenesis of SLE.
Primary aberrations of thin planar surface lenses (1980)

By using the Rayleigh–Sommerfeld diffraction formula of the first kind for the two-dimensional case, the impulse response of a thin planar lens is given and the influence of primary aberrations is considered. Respective degrading factors are recognized and a two-dimensional diffraction theory of aberrations in the Seidel approximation is presented. The influence of the material parameters and the geometry of the thin planar lens on the respective aberrations is discussed. The authors show that in several cases, not only spherical aberration but also field curvature is of concern. The thin planar lens as an imaging system and as a Fourier transformer is considered and two apertures—rectangular and Gaussian—are compared.
64-fs Pulses from a Kerr-Lens Modelocked Yb:LuO thin-disk laser (2017)

Summary form only given. Ultrafast thin-disk laser (TDL) oscillators generated up to 275 W in pulses with several hundred femtosecond duration [1]. However, the combination of high average output power with short pulse duration is challenging: the power levels of ultrafast TDL oscillators operating in sub-100-fs pulses are currently limited to the sub-10 W regime. In the last years Kerr-Lens Modelocking (KLM) has been established as a successful alternative to SESAM-modelocking of TDLs. The KLM technique has shown to be advantageous for achieving shorter pulse durations at high power levels [2]. So far, nearly all KLM TDLs use Yb:YAG, which is the best developed gain material for the thin-disk configuration but limited in its emission bandwidth. For achieving shorter pulse durations, it is highly attractive to study KLM TDLs based on gain materials with broader emission bandwidth. Yb:LuO exhibits a more than twice broader emission bandwidth than Yb:YAG [3]. Using SESAM-modelocking, Yb:LuO TDLs achieved 141 W in 740-fs pulses [4] and 7 W in 142 fs [5]. Recently, the first Yb:LuO KLM TDL has been demonstrated, generating 165-fs pulses with an output power of 5.9 W [6]. However, the full emission bandwidth of Yb:LuO was so far never exploited in a TDLHere we present a study on the optimization of the pulse duration of a KLM Yb:LuO TDL, resulting in more than twice shorter pulse duration than previously demonstrated from this gain material in the thin-disk configuration. In more than 200 configurations of one general laser cavity, we studied the influence of key parameters such as Kerr-nonlinearity, dispersion, degree of output coupling, and KLM aperture size. Our results show a trade-off between minimum pulse duration and average output power: at the shortest pulse duration of 64 fs, the output power is only 0.7 W, while it increases to 5.5 W for 83-fs pulses and 11.3 W for 131-fs pulses.

Diabetes and outcomes following guided de-escalation of antiplatelet treatment in acute coronary syndrome patients undergoing percutaneous coronary intervention: a pre-specified analysis from the randomised TROPICAL-ACS trial (2019)

Although diabetic status did not significantly interfere with the treatment effects of guided DAPT de-escalation, our results suggest that this approach might be safe and effective in non-diabetic patients. Further investigation is definitely warranted in diabetic patients.
A Novel Waveform-Tracking BLE Receiver (2022)

&lt;div&gt;&lt;div&gt;&lt;div&gt;&lt;div&gt;&lt;p&gt;We present a first-ever waveform-tracking receiver (RX) with type-II phase-tracking loop. In this preprint, a novel nonlinear filter in the feedback path is proposed to obtain better interference rejection performance. This digital nonlinear filter assists the receiver with tracking the waveform intelligently by predicting the incoming symbols; hence, we define this proposed RX as a waveform-tracking (WT)-RX. The simulation and preliminary measurement results are demonstrated in this paper. Moreover, we explore the issues of the current version WT-RX to provide guidance on possible future follow-up activities.&lt;/p&gt;&lt;/div&gt;&lt;/div&gt;&lt;/div&gt;&lt;/div&gt;
Many-body calculation of the surface-state energies for Si(111)2×1 (1991)

The surface-state excitation energies for the Si(111)2\ifmmode\times\else\texttimes\fi{}1 surface have been calculated in the GW approximation. The energy position and the dispersion of the occupied and empty surface states are in excellent agreement with photoemission and inverse-photoemission experiments. The calculated quasiparticle surface-state band gap, 0.62 eV, is 0.15 eV larger than the measured onset energy for electron-hole pair excitations. The possibility that excitonic effects are responsible for this difference is examined.
Grand canonical molecular dynamics (2003)

A hybrid molecular dynamics-Monte Carlo grand canonical simulation technique is developed for systems with constant chemical potential and temperature. The method ensures that the particle number and energy fluctuate according to the standard grand canonical probability distribution. Partial coupling and fractional particles are used to enhance the success of insertion and deletion attempts, and the method is shown to be feasible in dense liquids. The method is applied to a Lennard-Jones fluid and it gives the density as a function of chemical potential in agreement with known results. It is demonstrated that the transport coefficients can be obtained with the method by analyzing the influence of the stochastic perturbation on the diffusion constant for an isothermal system.
Cluster-based data modeling for semantic video search (2007)

In this paper we present a novel approach to query-by-example using existing high-level semantics in the dataset. Typically with visual topics, the examples are not sufficiently diverse to create robust model of the user's need in the descriptor's space. As a result, direct modeling using the provided topic examples as training data is inadequate. Otherwise, systems resort to multiple content-based searches using each example in turn, which typically provides poor results. We explore the relevance of visual concept models and how they help refine the query topics. We propose a new technique of leveraging the underlying semantics contained in the visual query topic examples to improve the search. We treat the semantic space as the descriptor space, and intelligently model a query in that space. We use unlabeled data to expand the diversity of the topic examples as well as provide a robust set of negative examples that allow direct modeling. The approach intelligently models a positive and pseudo-negative space using unbiased and biased methods for data sampling and data selection, and improves semantic retrieval by %12 over TRECVID 2006 topics. Moreover, we explore the visual context in fusion with text and visual search baselines and examine how this component can improve baseline retrieval results by expanding and re-ranking them. We apply the proposed methods in a multimodal video search system, and show how the underlined semantics of the queries can significantly improve the overall visual search results, improving baseline by over 46%, and enhancing performance of other modalities by at least 10%. We also demonstrate improved robustness over a range of query topic training examples and query topics with varying visual support of in TRECVID.
Increasing the darkfield contrast-to-noise ratio using a deconvolution-based information retrieval algorithm in X-ray grating-based phase-contrast imaging (2013)

A novel information retrieval algorithm for X-ray grating-based phase-contrast imaging based on the deconvolution of the object and the reference phase stepping curve (PSC) as proposed by Modregger et al. was investigated in this paper. We applied the method for the first time on data obtained with a polychromatic spectrum and compared the results to those, received by applying the commonly used method, based on a Fourier analysis. We confirmed the expectation, that both methods deliver the same results for the absorption and the differential phase image. For the darkfield image, a mean contrast-to-noise ratio (CNR) increase by a factor of 1.17 using the new method was found. Furthermore, the dose saving potential was estimated for the deconvolution method experimentally. It is found, that for the conventional method a dose which is higher by a factor of 1.66 is needed to obtain a similar CNR value compared to the novel method. A further analysis of the data revealed, that the improvement in CNR and dose efficiency is due to the superior background noise properties of the deconvolution method, but at the cost of comparability between measurements at different applied dose values, as the mean value becomes dependent on the photon statistics used.
A Flat Heat Pipe Architecture Based on Nanostructured Titania (2010)

A novel 3 cm × 3 cm × 600 μm-thick Ti-based flat heat pipe is developed for Thermal Ground Plane (TGP) applications. The Ti-based heat pipe architecture is constructed by laser welding two microfabricated titanium substrates to form a hermetically sealed vapor chamber. The scalable heat pipes' flat geometry facilitates contact with planar heat sources, such as microprocessor chip surfaces, thereby reducing thermal contact resistance and improving system packaging. Fluid transport is driven by the wicking structure in the TGP, which consists of an array of Ti pillars that are microfabricated from a titanium substrate using recently developed high-aspect-ratio Ti processing techniques. The hydrophilic nature of the Ti pillars is increased further by growing ~200-nm hairlike nanostructured titania of the pillar surfaces. The resulting super hydrophilic wick offers the potential to generate high wicking velocities of ~27.5 mm/s over distances of 2 mm. The experimental wetting results show a diffusive spreading behavior that is predicted by Washburn dynamics. The maximum effective thermal conductivity of a heat pipe is directly related to the speed of capillary flow of the working fluid through the wick and is measured experimentally in the first-generation device to be k = 350 W/m · K. A dummy TGP with a cavity volume of ~170 μL was used to test the hermiticity level of the laser packaging technique. The device gave a 0.067% of water loss based on ~60 μL of charged water at 100°C in air for over a year.
Efficient adaptive arithmetic coding based on updated probability distribution for lossless image compression (2010)

We propose an efficient lossless compression scheme for still images based on arithmetic coding. The scheme presents a novel adaptive arithmetic coding that updates the probabilities of pixels only after detecting the last occurrence of each pixel and then removes the redundancy from the original image effectively. The proposed approach has interestingly low computational complexity. In addition, unlike other statistical coding techniques, arithmetic coding in the proposed scheme is not solely dependent on the pixel probability distribution but also on the image block sorting. The proposed method is compared to both static and adaptive order-0 models while taking into account compression ratios and processing time. Experimental results, based on a set of 100 gray-level images, demonstrate that the proposed scheme gives mean compression ratios that are 5.5% higher than those by the conventional arithmetic encoders as well as significantly faster than the order-0 adaptive arithmetic coding.

NANOFIBROUS MATERIALS WITH ANISOTROPIC STRUCTURES DEPOSITED BY ELECTROSPINNING (2011)

Nanofibrous materials are very promising for tissue engineering thanks to similarities of their intrinsic structure with extracellular matrix (ECM). Properly selected biocompatible material or their blend converted into the nanofibers can improve formation of new tissues (skin, muscles, bone, etc.). Moreover, specially designed nanomaterials can satisfy requirements for directional migration and proliferation of seeded stem cells and help with formation of engineered 3D ECM with anisotropic structure (nerve or vascular tissues replacements for example). Nanofibrous materials with anisotropic properties are highly suitable for applications in electronic and optics as well.Our work deals with a production of nanomaterials by electrospinning (ES) which have uniaxially or multiaxially ordered inner structure. Review study of recent technical abilities of ES method modifications based on patents and scientific papers are presented. The most important principles useful for industrial production were tested in our laboratories. Theoretical backgrounds of uniaxially aligned nanofibers formation on a patterned collector with obtained practical results are shown. Advanced collector; designed with optimal parameters set; collecting nanofibers with extremely high orientation order parameter (higher than 97 %) is introduced. Material and anisotropic properties of nanofibrous layers are discussed in detail.Prepared materials in CPN laboratories are currently tested for biological properties and we believe they are very promising and ready for direct application.
Synthesis and Characterization of New Pentacoordinate Iron‐Based Aryloxide Complexes (2012)

Abstract Heterobimetallic lithium–iron coordination compounds are interesting targets for several reasons: they can be used as precursors for mixed metal oxides, as catalysts, for example, for ring‐opening polymerization reactions or to study oxidation/reduction processes. Finally their magnetic properties are also of interest. New heterobimetallic aryloxide complexes, namely [(thf) 4 Li 3 Fe(OPh) 3 (O 2 C 6 H 4 )Cl] 2 ( 1 ), [{(thf) 3 Li 3 Fe(OPh) 5 Cl} 3 ] n ( 2 ), and [(thf) 3 Li 3 Fe(OPh) 6 ] 2 ( 3 ), have been synthesized and characterized by single‐crystal X‐ray diffraction. While compounds 1 and 3 were synthesized by an oxidative substitution reaction, compound 2 was directly obtained from the Fe III salt. These compounds are accessible by both synthetic pathways. Additionally, in compound 1 , the phenoxy ligand was catalytically oxidized to ortho ‐catechol, which was incorporated into the structure of 1 as a ligand that coordinates strongly to iron. All compounds feature the Fe III ion with a trigonal, bipyramidal environment, with coordination number 5.
Human and yeast Rad52 proteins promote DNA strand exchange (2004)

Studies of rad52 mutants in Saccharomyces cerevisiae have revealed a critical role of Rad52 protein in double-strand break repair and meiosis, and roles in both RAD51-dependent and -independent pathways of recombination. In vitro, both yeast and human Rad52 proteins play auxiliary roles with RPA in the action of Rad51. Rad52 also has annealing activity and promotes the formation of D-loops in superhelical DNA. The experiments described here show that Homo sapiens (Hs)Rad52 and yeast Rad52 proteins promote strand exchange as well. Strand exchange was promoted by the N-terminal domain of HsRad52 that contains residues 1-237, which includes the residues required to form rings of Rad52, whereas other truncated domains, both N-terminal and C-terminal, were inactive. For both yeast Rad52 and HsRad52, the yield of strand-exchange reactions was proportional to the fractional A.T content of the DNA substrates, but both enzymes catalyzed exchange with substrates that contained up to at least 50% G.C. Observations made on S. cerevisiae Rad52 protein from mutants with severe recombination deficiencies indicate that the strand-exchange activity measured in vitro reflects a biologically significant property of Rad52 protein.
Autonomic management policy specification in Tune (2008)

Distributed software environments are increasingly complex and difficult to manage, as they integrate various legacy software with specific management interfaces. Moreover, the fact that management tasks are performed by humans leads to many configuration errors and low reactivity. This is particularly true in medium or large-scale distributed infrastructures.
A design of the low-pass filter using the novel microstrip defected ground structure (2001)

A new defected ground structure (DGS) for the microstrip line is proposed in this paper. The proposed DGS unit structure can provide the bandgap characteristic in some frequency bands with only one or more unit lattices. The equivalent circuit for the proposed defected ground unit structure is derived by means of three-dimensional field analysis methods. The equivalent-circuit parameters are extracted by using a simple circuit analysis method. By employing the extracted parameters and circuit analysis theory, the bandgap effect for the provided defected ground unit structure can be explained. By using the derived and extracted equivalent circuit and parameters, the low-pass filters are designed and implemented. The experimental results show excellent agreement with theoretical results and the validity of the modeling method for the proposed defected ground unit structure.
Requirements for Eomesodermin and Promyelocytic Leukemia Zinc Finger in the Development of Innate-Like CD8+ T Cells (2011)

Conventional and nonconventional T cell development occur in the thymus. Nonconventional thymocytes that bear characteristics typically associated with innate immune cells are termed innate-like lymphocytes (ILLs). Mice harboring a tyrosine to phenylalanine mutation in the adaptor protein Src homology 2 domain-containing leukocyte protein of 76 kDa at residue 145 (Y145F mice) develop an expanded population of CD8(+)CD122(+)CD44(+) ILLs, typified by expression of the T-box transcription factor eomesodermin. Y145F mice also have an expanded population of γδ T cells that produce copious amounts of IL-4 via a mechanism that is dependent on the BTB-ZF transcription factor promyelocytic leukemia zinc finger. Using mice with T cell-specific deletion of Eomes, we demonstrate that this transcription factor is required for CD8(+) ILL development in Y145F as well as wild-type mice. Moreover, we show that promyelocytic leukemia zinc finger and IL-4 are also required for the generation of this ILL population. Taken together, these data shed light on the cell-intrinsic and cell-extrinsic factors that drive CD8(+) ILL differentiation.
Land Data Regularization and Interpolation Using Azimuth Moveout (AMO) (2006)

Azimuth Moveout (AMO) is a wave-equation correct binning algorithm that accurately handles dipping geological strata and variable velocities. AMO has applications for both marine and land data, though this paper focuses mainly on the application of AMO to 3-D and 2-D land surveys which have irregular and sparse geometry that often leads to spatial aliasing. AMO can be successfully used to regularize and interpolate land data, while preserving steep dips and diffractions better than standard binning.&lt;br&gt;Traditionally, AMO was designed to address the marine acquisition shortcomings, and regularize the data. Recent focus by exploration and production companies to exploit shallow resource plays has demanded new research into utilizing existing 3D data for mapping the shallow reservoirs. The land examples provided in this paper demonstrate the success of applying AMO to conventional land 3-D data.&lt;br&gt;

Pulmonary Microwave Ablation Near the Heart: Antenna Positioning Can Mitigate Cardiac Complications in a Porcine Model (2016)

Purpose To determine how close to the heart pulmonary microwave ablation can be performed without causing cardiac tissue injury or significant arrhythmia. Materials and Methods The study was performed with approval from the institutional animal care and use committee. Computed tomographic fluoroscopically guided microwave ablation of the lung was performed in 12 swine. Antennas were randomized to either parallel (180° ± 20°) or perpendicular (90° ± 20°) orientation relative to the heart surface and to distances of 0-10 mm from the heart. Ablations were performed at 65 W for 5 minutes or until a significant arrhythmia (asystole, heart block, bradycardia, supraventricular or ventricular tachycardia) developed. Heart tissue was evaluated with vital staining and histologic examination. Data were analyzed with mixed effects logistic regression, receiver operating characteristic curves, and the Fisher exact test. Results Thirty-four pulmonary microwave ablations were performed with the antenna a median distance of 4 mm from the heart in both perpendicular (n = 17) and parallel (n = 17) orientation. Significant arrhythmias developed during six (18%) ablations. Cardiac tissue injury occurred with 17 ablations (50%). Risk of arrhythmia and tissue injury decreased with increasing antenna distance from the heart with both antenna orientations. No cardiac complication occurred with a distance of greater than or equal to 4.4 mm from the heart. The ablation zone extended to the pleural surface adjacent to the heart in 71% of parallel and 17% of perpendicular ablations performed 5-10 mm from the heart. Conclusion Microwave lung ablations performed more than or equal to 5 mm from the heart were associated with a low risk of cardiac complications. <sup>©</sup> RSNA, 2016.
