The complex transmission coefficient for millimeter and submillimeter waves incident on a ${\mathrm{Ba}}_{0.6}$${\mathrm{K}}_{0.4}$${\mathrm{BiO}}_{3}$ thin film (82 nm) has been measured over a frequency range of 200--1200 GHz at temperatures above and below ${\mathit{T}}_{\mathit{c}}$ using coherent time-domain spectroscopy. We observe a dramatic change in both the magnitude and phase of the terahertz transmission in the superconducting state caused by a rapid carrier condensation. Both the real (${\mathrm{\ensuremath{\sigma}}}_{1}$) and imaginary (${\mathrm{\ensuremath{\sigma}}}_{2}$) parts of the complex conductivity are determined directly from the amplitude and phase of the transmitted electric field without the need for a Kramers-Kr\"onig analysis. By fitting ${\mathrm{\ensuremath{\sigma}}}_{2}$ in the framework of BCS theory, a superconducting gap 2\ensuremath{\Delta}(0)=6.9 meV=3.8${\mathit{k}}_{\mathit{B}}$${\mathit{T}}_{\mathit{c}}$ is obtained. Below ${\mathit{T}}_{\mathit{c}}$, the ${\mathrm{\ensuremath{\sigma}}}_{1}$ is rapidly enhanced for \ensuremath{\omega}/2\ensuremath{\pi}500 GHz, which is attributed to the BCS coherence effects. However, the conductivity exhibits monotonic temperature dependence and no clear ${\mathrm{\ensuremath{\sigma}}}_{1}$(T) peak is observed throughout the frequency range measured. The high-frequency penetration depth (\ensuremath{\sim}600 nm) is also extracted and discussed. Our results are consistent with a picture of BCS moderate coupling superconductivity in an intermediate to dirty limit.
Design of pulse transformers for PFL charging (1979)

Air core pulse transformers powered by low voltage capacitor banks can be simple efficient systems for charging high-voltage (0.5 to 3 MV), pulse forming transmission lines (PFL) such as those used in electron and ion beam accelerators. In these applications pulse transformers must have the combined capability of high voltage endurance and high energy transfer efficiency, particularly in repetitive pulse systems where these features are of primary importance. The design of shielded, high-voltage, spiral, strip transformers which fulfill these requirements is described in this paper. Transformers of this type have been tested in three systems which operate with greater than 90% transfer efficiency and have not failed in over 10/sup 7/ shots.

Sequence summarizing neural network for speaker adaptation (2016)

In this paper, we propose a DNN adaptation technique, where the i-vector extractor is replaced by a Sequence Summarizing Neural Network (SSNN). Similarly to i-vector extractor, the SSNN produces a "summary vector", representing an acoustic summary of an utterance. Such vector is then appended to the input of main network, while both networks are trained together optimizing single loss function. Both the i-vector and SSNN speaker adaptation methods are compared on AMI meeting data. The results show comparable performance of both techniques on FBANK system with frame-classification training. Moreover, appending both the i-vector and "summary vector" to the FBANK features leads to additional improvement comparable to the performance of FMLLR adapted DNN system.
Contemporaneous positron emission tomography and MR imaging at 1.5 T (1999)

Simultaneous acquisition of positron emission tomography (PET) and magnetic resonance (MR) images using an MR-compatible PET system will obviate the need for image registration and will allow unique studies of structure and function of living organisms in one setting. Here we report on simultaneous acquisition of PET and MR images on a clinical 1.5 T system using a 54 mm diameter prototype MR-compatible PET system (McPET). Phantom experiments were performed in order to determine the effect of the McPET system on MR images. The results demonstrated the system to be fully MR compatible, in both its detector head construction and operation. The McPET construction offers a promising method for design of a large-scale MR-compatible PET system that will be useful in functional studies of the brain. J. Magn. Reson.

Induced convolution operator norms of linear dynamical systems (1999)

In this paper we develop explicit formulas for induced convolution operator norms and their bounds. These results generalize established induced operator norms for linear dynamical systems with various classes of input-output signal pairs.
Functional DNA switches: rational design and electrochemical signaling (2013)

Recent developments in nanoscience research have demonstrated that DNA switches (rationally designed DNA nanostructures) constitute a class of versatile building blocks for the fabrication and assembly of electronic devices and sensors at the nanoscale. Functional DNA sequences and structures such as aptamers, DNAzymes, G-quadruplexes, and i-motifs can be readily prepared in vitro, and subsequently adapted to an electrochemical platform by coupling with redox reporters. The conformational or conduction switching of such electrode-bound DNA modules in response to an external stimulus can then be monitored by conventional voltammetric measurements. In this review, we describe how we are able to design and examine functional DNA switches, particularly those systems that utilize electrochemical signaling. We also discuss different available options for labeling functional DNA with redox reporters, and comment on the function-oriented signaling pathways.
Anisotropy of Mechanical Properties of Pinctada margaritifera Mollusk Shell (2020)

The mechanical properties such as compressive strength and nanohardness were investigated for <i>Pinctada margaritifera</i> mollusk shells. The compressive strength was evaluated through a uniaxial static compression test performed along the load directions parallel and perpendicular to the shell axis, respectively, while the hardness and Young modulus were measured using nanoindentation. In order to observe the crack propagation, for the first time for such material, the in-situ X-ray microscopy (nano-XCT) imaging (together with 3D reconstruction based on the acquired images) during the indentation tests was performed. The results were compared with these obtained during the micro-indentation test done with the help of conventional Vickers indenter and subsequent scanning electron microscopy observations. The results revealed that the cracks formed during the indentation start to propagate in the calcite prism until they reach a ductile organic matrix where most of them are stopped. The obtained results confirm a strong anisotropy of both crack propagation and the mechanical strength caused by the formation of the prismatic structure in the outer layer of <i>P. margaritifera</i> shell.

Learning Hierarchical Semantic Image Manipulation through Structured Representations (2018)

Understanding, reasoning, and manipulating semantic concepts of images have been a fundamental research problem for decades. Previous work mainly focused on direct manipulation on natural image manifold through color strokes, key-points, textures, and holes-to-fill. In this work, we present a novel hierarchical framework for semantic image manipulation. Key to our hierarchical framework is that we employ a structured semantic layout as our intermediate representation for manipulation. Initialized with coarse-level bounding boxes, our structure generator first creates pixel-wise semantic layout capturing the object shape, object-object interactions, and object-scene relations. Then our image generator fills in the pixel-level textures guided by the semantic layout. Such framework allows a user to manipulate images at object-level by adding, removing, and moving one bounding box at a time. Experimental evaluations demonstrate the advantages of the hierarchical manipulation framework over existing image generation and context hole-filing models, both qualitatively and quantitatively. Benefits of the hierarchical framework are further demonstrated in applications such as semantic object manipulation, interactive image editing, and data-driven image manipulation.
Measurement Accuracy of the Body Weight with Smart Insoles (2018)

A participant wearing the Pedar-X performed 6 activities on level ground: Slow, medium and fast walk, medium and fast run, and limping. Static BW was measured prior each activity. The dynamic and static BWs were calculated from the mean of the sum of forces of both feet over time and compared to the force measured from the force-plate. As the base pressure during the swing phase was not zero, it was treated in 3 ways: including the base pressure; subtracting the mean base pressure from the swing phase; subtraction of the base pressure from the entire signal. The calculated BWs were normalised to the actual BW of the participant. From the results, the BWs calculated had 10% error when static and 6% error when walking. To zero or subtract the baseline pressures improved the BW measurement by 1.75% and 4% respectively. Running data could not be analysed at a sampling rate of 50 Hz.

Experimental investigation of heterogeneous compressible shear layers (1987)

The compressible, two-dimensional shear layer is investigated experimentally in a novel facility. In this facility, it is possible to flow similar or, dissimilar gases of different densities and to select different Mach numbers for each stream over a wide range of Reynolds numbers. In the current experiments, ten combinations of gases and Mach numbers are studied in which the freestream Mach numbers range from 0.2 to 4, the density ratio varies from 0.2 to 9.2, and the velocity ratio varies from 0.13 to 1. The growth of the turbulent region of the layer is measured by means of pitot pressure profiles obtained at several streamwise locations. The resulting growth rate is estimated to be about 80% of the visual growth rate. The transition from laminar to turbulent flow, as well as the structure of the turbulent layer, are observed with Schlieren photographs of 20 nanosecond duration. Streamwise pressure distribution and total pressures are measured by means of a Scanivalve-pressure transducer system. An underlying objective of this investigation was the definition of a compressibility-effect parameter that correlates and consolidates the experimental results, especially the turbulent growth rates. A brief analytical investigation of the vortex sheet suggests that such a parameter is the Mach number in a frame of reference moving with the phase speed of the disturbance, called here the convective Mach number. In a similar manner, the convective Mach number of a turbulent shear layer is defined as the one seen by an observer moving with the convective velocity of the dominant waves and structures. It happens to have about the same value for each stream. In the current experiments, it ranges from 0 to 1.9. The correlations of the growth rate with convective Mach number fall approximately onto one curve when the growth rate is normalized by its incompressible value at the same velocity and density ratios. The normalized growth rate, which is unity for incompressible flow, decreases gradually with increasing convective Mach number, reaching an asymptotic value of about 0.25 for supersonic convective Mach numbers. The above behavior is in qualitative agreement with results of linear stability theory as well as with those of previous, one-stream experiments. Large-scale structures, resembling those observed in subsonic shear layers, are evident in the Schlieren photographs. It is estimated that the mean structure spacing, normalized by the local thickness, is reduced to about half its incompressible value as the convective Mach number becomes supersonic. An estimate of the transition Reynolds number has been obtained from the photographs of two shear layers having quite different convective Mach numbers, one low subsonic and the other sonic. In both cases, it is about 2 x 105, based on distance to transition and properties of the high unit Reynolds number stream, thus suggesting that, in this experiment, transition is dominated by instabilities of the wake, rather than of the shear layer.
Mechanisms determining safety and performance of brain stimulating electrodes (2009)

Electrical current is widely used to interact with or stimulate neural systems. Current transduction from device to tissue is mediated at the electrode-tissue interface by capacitive charge and electrochemistry. This charge-passing-capacity is frequency dependent. While safety parameters have been established for high-frequencies, safety has not been fully determined for novel materials and pulse frequencies significantly lower than 100 Hz. We are explicitly interested in safety parameters and performance of charge passing at low frequencies (<<100 Hz) for neural systems. We present a visual study of pH during charge passing for electrodeposited iridium oxide electrodes. Clear reaction-diffusion waves are observed that extend many hundreds of micrometers from the electrode surface.
Electrochemical synthesis of C-glycosides as non-natural mimetics of biologically active oligosaccharides (2012)

Natural oligosaccharides inhibitors of heparanase and selectins are emerging as promising drugs for\ncancer therapy. As an alternative tool to the natural ones, sulfated tri maltose C-C-linked dimers\n(alfa,alfa alfa,beta and beta,beta STMCs) were prepared by bromo-maltotriose electroreduction on silver cathode,1\nfollowed by sulfation. The presence of an interglycosidic C-C bond makes STMCs less vulnerable\nto metabolic processing then their O-analogues. For this reason, STMCs have been studied as drug\ncandidates and inhibitors of carbohydrate processing enzymes. Their activity as inhibitor of Pselectin\nin vivo and in the attenuation of metastasis both on B16-BL6 melanoma cells and on MC-\n38 carcinoma cells2 prompted to the optimization of their synthetic process. Therefore, the\nelectrochemical process for the C-C coupling of the model molecule acetobromoglucose has been\ninvestigated by changing various reaction conditions such as solvent and arrangement of the\nelectrolytic cell, aiming at the final scale-up of the reaction.

The Evolution of Clinical Trials in Oncology: Defining Who Benefits from New Drugs Using Innovative Study Designs (2017)

Historically, advocates of randomized drug treatment trials in oncology contributed to the changing paradigm for testing cancer treatments in the U.S., which led to global efforts to generate evidence of promise in preclinical model systems and translate those findings into improved patient outcomes. In the age of genomic medicine, the challenge to speed the evolution of how clinical trials are conducted in patients with cancer continues.
Corneal degenerations. (1979)

Corneal degenerations are among the most commonly observed clinical disorders in ophthalmology. They may be classified as (1) aging changes, (2) depositions, and (3) marginal degenerations. Aging changes are often incidental findings and do not usually interfere with vision. Depositions can occur secondary to previous ocular disease or trauma. Marginal degenerations are generally of unknown etiology, however, they may sometimes accompany a systemic disorder. The diseases in this latter group are usually the most difficult to treat and the most visually disabling.

Ion acceleration using high-contrast ultra-intense lasers (2006)

We have compared the acceleration of high-energy ions from the rear-surface of thin foils for various contrast conditions of the ultra-intense laser pulse irradiating the targets. The experiments were performed using the LULI 100 TW facility. We used Al targets of variable thicknesses and the laser pulse contrast ratio ahead of the main pulse was varied using either a fast Pockels cell or a single or double plasma mirror. The latter was installed at an intermediate field position, in between the focusing optics and the target, so that its effect was optimized. By improving with these two methods the laser pulse contrast, we have observed that we could significantly reduce the thickness of the target used for proton acceleration and at the same time increase both the cut-off energy of the accelerated protons and the energy conversion efficiency of the process.

Robust Identification of Audio Using Watermarking and Fingerprinting (2004)

This chapter argues that the reader is sufficiently familiar with audio watermarking to allow him to appreciate the analysis on the pros and cons of this technique with respect to the audio fingerprinting technique discussed next. It introduces the reader to the basic technical aspects of audio fingerprinting. The chapter provides an analysis on the commonalities and the differences between watermarking and fingerprinting and the reader with insights on which identification technology to use in which application. It discusses some issues for future research and presents the essential ingredients of an audio fingerprinting technology developed at Philips Research. The chapter argues that the choice for a particular technology is highly application dependent. It focuses on the different parameters of an audio fingerprint system, and presents the main parameters: robustness; reliability; fingerprint size; granularity; and search speed and scalability. The subfingerprints are obtained by comparing and thresholding energy differences. The proposed fingerprint extraction scheme is based on this general streaming approach.
