Waveform relaxation based hardware-in-the-loop simulation (2014)

This thesis introduces an alternative potentially low cost solution for hardware-in-the-loop (HIL) simulation based on the waveform relaxation (WR) method. The WR tech-nique is extended so that, without the need for a real-time simulator, the behaviour of an actual piece of physical hardware can nevertheless be tested as though it were connected to a large external electrical network. This is achieved by simulating the external network on an off-line electromagnetic transients (EMT) simulation program, and utilizing iterative exchange of waveforms between the simulation and the hardware by means of a spe-cialized Real-Time Player/Recorder (RTPR) interface device. The approach is referred to as waveform relaxation based hardware-in-the-loop (WR-HIL) simulation. To make the method possible, the thesis introduces several new innovations for stabi-lizing and accelerating the WR-HIL algorithm. It is shown that the classical WR shows poor or no convergence when at least one of the subsystems is an actual device. The noise and analog-digital converters’ quantization errors and other hardware disturbances can affect the waveforms and cause the WR to diverge. Therefore, the application of the WR method in performing HIL simulation is not straightforward and the classical WR need to be modified accordingly. Three convergence techniques are proposed to improve the WR-HIL simulation con-vergence. Each technique is evaluated by an experimental example. The stability of the WR-HIL simulation is studied and a stabilization technique is proposed to provide suffi-cient conditions for the simulation stability. The approach is also extended to include the optimization of the parameters of power system controllers located in geographically distant places. The WR-HIL simulation technique is presented with several examples. At the end of the thesis, suggestions for the future work are presented.
Statistical models for classification and synthesis of textures (1994)

Cumulants are employed for classification and synthesis of textured images because they suppress additive Gaussian noise of unknown covariance and are capable of resolving phase and causality issues in stationary non-Gaussian random fields. Their performance is compared with existing autocorrelation-based approaches that offer sample estimates of smaller variance and lower computational complexity. Nonlinear matching techniques are better than linear equation methods in estimating parameters of non-Gaussian random fields especially under model mismatch. Seasonal 1-D sequences allow for semistationary 2-D models, and their performance is illustrated on synthetic spacevariant textures. The potential of prolate spheroidal basis expansion is also described briefly for parsimonious nonstationary modeling of spacevariant textured images.
Trimesitylboron−: A Nonplanar Aromatic Negative Ion (1972)

An analysis of the liquid solution ESR spectrum of the negative ion of trimesitylboron is presented together with a discussion of the rigid medium spectrum. Two anomalies in the spectra, the absence of an alkali metal coupling and the positive sign of Δ g = g‖ − g⊥, are pointed out and interpreted in terms of the nonplanarity of the hydrocarbon.
Rate-limiting effects of Cyclin D1 in transformation by ErbB2 predicts synergy between herceptin and flavopiridol. (2002)

Cyclin D1 is downstream of erbB2 and is required for erbB2 transformation. Here we report thatcyclin D1 functions are essential, rate limiting for erbB2 transformation, and reciprocally increase erbB2 levels. This interaction depends on three cyclin D1 activities: cyclin-dependent kinase 4-dependent kinase activity, titration of p27, and an intrinsic transcriptional activity of cyclin D1. Drugs active against erbB2 and cyclin D1 (Herceptin and flavopiridol) were synergistically cytotoxic against erbB2-positive breast cancer cell lines. Addition of flavopiridol to Herceptin synergistically lowered erbB2 levels in these cells. Our data suggest the potential use of combinations of cyclin-dependent kinase inhibitors and Herceptin in breast cancer.
On the Sample Complexity of End-to-end Training vs. Semantic Abstraction Training (2016)

We compare the end-to-end training approach to a modular approach in which a system is decomposed into semantically meaningful components. We focus on the sample complexity aspect, in the regime where an extremely high accuracy is necessary, as is the case in autonomous driving applications. We demonstrate cases in which the number of training examples required by the end-to-end approach is exponentially larger than the number of examples required by the semantic abstraction approach.

Boron, Aluminum, and Gallium Silsesquioxane Compounds, Homogeneous Models for Group 13 Element-Containing Silicates and Zeolites (2002)

The incompletely condensed hydroxysilsesquioxanes R7Si7O9(OH)3 and R7Si7O9(OH)2OSiMePh2 (R = c-C5H9, c-C6H11) have been used to form Lewis and Brønsted acidic boron and gallium silsesquioxane compounds. Treatment of (c-C5H9)7Si7O9(OH)3 with BI3 in the presence of an amine yielded the dimeric {[(c-C5H9)7Si7O12]B}2 (1). Compound 1 was also obtained when (c-C5H9)7Si7O9(OH)3 was reacted with LiBH4, eliminating LiH. On the other hand, treatment of LiBH4 with 2 equiv of (c-C5H9)7Si7O9(OH)2OSiMePh2 gave the solvent-free lithium borate salt {[(c-C5H9)7Si7O11(OSiMePh2)]2B}-{Li}+ (2). Reaction of GaCl3 with (c-C6H11)7Si7O9(OH)3 in the presence of NEt3 afforded the thermally robust amine adduct [(c-C6H11)7Si7O12]Ga·NEt3 (3). A similar reaction of GaCl3 with 2 equiv of (c-C5H9)7Si7O9(OH)2OSiMePh2 gave the ammonium gallate {[(c-C5H9)7Si7O11(OSiMePh2)]2Ga}-{Et3NH}+ (4). Attempts to obtain the corresponding Brønsted acid of 4, as could be obtained for aluminum, invariably failed. Nevertheless, ammonium salt 4 reacts as a masked Brønsted acid with the basic GaMe3 to yield the dimethyl gallium gallate [(c-C5H9)7Si7O11(OSiMePh2)]2Ga(GaMe2) (5). The equimolar reaction between GaMe3 and R7Si7O9(OH)3 selectively yielded {[R7Si7O11(OH)]GaMe}2 (R = c-C5H9 (6a), c-C6H11 (6b)). The fact that in 6a/b gallium methyl and silanol functionalities coexist clearly demonstrates the lower reactivity of gallium-alkyls compared to aluminum-alkyl groups. The equimolar reaction of GaMe3 with the monosilylated (c-C5H9)7Si7O9(OH)2OSiMePh2 yielded {[(c-C5H9)7Si7O11(OSiMePh2)]GaMe}2 (7) as a 5:1:40 mixture of three conformational isomers, similar to what was observed for the corresponding methyl aluminum silsesquioxanes. The kinetic and thermodynamic stability of 7 and its chemical isomer 5 has been investigated. Isomerization experiments show that both 5 and the main conformer of 7 isomerize to a thermodynamic stable mixture of isomers of 7 with a 2:1:2 ratio. The dimethyl gallium silsesquioxane {[(c-C5H9)7Si7O11(OSiMePh2)]2(GaMe2)4} (8) was formed quantitatively upon treating {[(c-C5H9)7Si7O9(OH)2OSiMePh2 with 2 equiv of GaMe3. Likewise, reacting {[(c-C5H9)7Si7O9(OH)3 with 3 equiv of GaMe3 yielded the dimerc {[(c-C5H9)7Si7O12]2(GaMe2)6} (9). The high tendency of gallium to obtain a tetrahedral coordination results in a crowded structure 9 with remarkable low fluxionality. Compounds 2, 4, 5, 6b, 8, and 9 have been structurally characterized.

Capacitively-aided switching technique for high-frequency isolated bus converters (2016)

This paper presents a new capacitively-aided zero voltage switching (ZVS) technique for isolated bus converters. The proposed technique helps to achieve ZVS conditions for both inverter and rectifier switches with the aid of magnetizing current of the transformer and capacitors interconnecting primary and secondary side switching nodes. With the proposed topology, the ZVS conditions for inverter and rectifier switches occur at the same time, and (ideally) maintain constant required dead time independent of the load level of the converter. These features are particularly advantageous especially for designs operating at high frequencies where timing control becomes critical. The proposed approach is demonstrated in a 1.4 MHz prototype converter which operates from 36 Vdc and supplies a 12 Vdc output load (i.e., fixed input voltage and fixed voltage transformation ratio, 3 : 1 ) at a 36 W rating. Experimental results show ZVS operation of all devices independent of the load level, and the prototype converter achieves 94% peak efficiency with 300 W/ in3 power density.
An analysis/synthesis tool for transient signals that allows a flexible sines+transients+noise model for audio (2002)

We present a flexible analysis/synthesis tool for transient signals that extends current sinusoidal and sines+noise models for audio to sines+transients+noise. The explicit handling of transients provides a more realistic and robust signal model. Because the transient model presented is the frequency domain dual to sinusoidal modeling, it has similar flexibility and allows for a wide range of transformations on the parameterized signal. In addition, due to this duality, a major portion of the transient model is sinusoidal modeling performed in the frequency domain. In order to make the transient and sinusoidal models work more effectively together, we present a formulation of sinusoidal modeling (and therefore transient modeling) in terms of matching pursuits and overlap-add synthesis. This formulation provides a tight coupling between the sines+transients+noise model because it allows a simple heuristic, based on tonality, as to when an audio signal should be modeled as sines and/or transients and/or noise.

PFO closure: rational, procedure and devices. (2014)

Patent foramen ovale (PFO) is a common anatomical variant occurring in 20-25% of the population. In most cases, a PFO remains asymptomatic. However it allows for any venous particle such as thrombus, air or vasoactive substances to bypass the lung and enter the arterial circulation. Accordingly, PFO's have been linked to cryptogenic stroke, migraine and decompression illness. While the number of device closures have been increasing the therapy remains controversial as ‑ until recently ‑ data supporting PFO closure came from non randomized studies only. In this review we will discuss the existing data on PFO closure including results of the three randomized controlled trials comparing device closure with medical therapy in patients with cryptogenic stroke. We will also focus on the implantation technique, the complications and the different devices that are used for this procedure.
Evaluation of a swept-laser optical coherence tomography light source based on a novel quantum-dot based semiconductor optical amplifier (2011)

We describe a simple swept-laser design that characterizes the emission bandwidth, linewidth, spectral shape and output noise. A short cavity Littmann configuration is used in which the semiconductor optical amplifier (SOA) lasing wavelength is tuned by a galvanometer with an 830 grooves per mm diffraction grating. A 3dB coupler extracts light from the cavity formed by the grating and end-mirror and the optical output uses to illuminate a balanced swept source optical coherence tomography (SS-OCT) interferometer incorporating a circulator, 3dB coupler, dispersion compensator and balanced detector. The SOA (SOA-1200-70-PM-20sB, Innolume GmbH) uses a novel III-V semiconductor quantum-dot gain medium. ASE is emitted between 1150nm and 1300nm at a drive current of 700mA. When used in the Littmann cavity laser a coherence length of about 10mm is produced, which is tunable over 60nm. The peak output power is 12mW. The swept-laser has been incorporated into a fiber-based SS-OCT system and used to image biological tissues. Axial resolution in air is 12 microns. Images of human palmar skin in-vivo are demonstrated, showing good resolution and contrast, with the stratum corneum, epidermis, rete ridges and epidermal-dermal junction visualized.

Alterations in Postprandial Hepatic Glycogen Metabolism in Type 2 Diabetes (2004)

Decreased skeletal muscle glucose disposal and increased endogenous glucose production (EGP) contribute to postprandial hyperglycemia in type 2 diabetes, but the contribution of hepatic glycogen metabolism remains uncertain. Hepatic glycogen metabolism and EGP were monitored in type 2 diabetic patients and nondiabetic volunteer control subjects (CON) after mixed meal ingestion and during hyperglycemic-hyperinsulinemic-somatostatin clamps applying 13C nuclear magnetic resonance spectroscopy (NMRS) and variable infusion dual-tracer technique. Hepatocellular lipid (HCL) content was quantified by 1H NMRS. Before dinner, hepatic glycogen was lower in type 2 diabetic patients (227 +/- 6 vs. CON: 275 +/- 10 mmol/l liver, P < 0.001). After meal ingestion, net synthetic rates were 0.76 +/- 0.16 (type 2 diabetic patients) and 1.36 +/- 0.15 mg x kg(-1) x min(-1) (CON, P < 0.02), resulting in peak concentrations of 283 +/- 15 and 360 +/- 11 mmol/l liver. Postprandial rates of EGP were approximately 0.3 mg x kg(-1) x min(-1) (30-170 min; P < 0.05 vs. CON) higher in type 2 diabetic patients. Under clamp conditions, type 2 diabetic patients featured approximately 54% lower (P < 0.03) net hepatic glycogen synthesis and approximately 0.5 mg x kg(-1) x min(-1) higher (P < 0.02) EGP. Hepatic glucose storage negatively correlated with HCL content (R = -0.602, P < 0.05). Type 2 diabetic patients exhibit 1) reduction of postprandial hepatic glycogen synthesis, 2) temporarily impaired suppression of EGP, and 3) no normalization of these defects by controlled hyperglycemic hyperinsulinemia. Thus, impaired insulin sensitivity and/or chronic glucolipotoxicity in addition to the effects of an altered insulin-to-glucagon ratio or increased free fatty acids accounts for defective hepatic glycogen metabolism in type 2 diabetic patients.
Asymmetric rotational axis reconstruction of grating-based x-ray phase contrast tomography of the human cerebellum (2012)

The brain has an outstanding functional importance in the human organism. Therefore, there is a strong need for three-dimensional brain imaging modalities. Magnetic resonance imaging provides deep insights but its spatial resolution is insufficient to study the structure on the cellular level. X-ray absorption microtomography yields the necessary spatial resolution, but shows only marginal contrast between the different types of brain tissue. Alternatively, differential X-ray phase contrast obtained with grating interferometry, which is known for much better differentiations between soft tissues can be used for the visualization of the human brain. As important structures of the human brain such as the human thalamus have dimensions of several centimeters, a large field of view is required. In the present communication, we report an evaluation of grating-based X-ray phase contrast microtomography in the off-axis modus which allows to expand the field of view up to a factor of two but may reduce the image quality. We demonstrate that tomograms with comparable contrast-to-noise values, about 10%, and 50% inferior spatial resolution can be generated with off-axis measurements. As one can reduce the effective pixel size up to a factor of two, the choice of an asymmetrical rotation axis can give rise to an improvement of the spatial resolution by 20%.

Error Analysis of ZUPT-Aided Pedestrian Inertial Navigation (2018)

We present, for the first time, an analytical relation between the navigation errors during Zero-Velocity-Update (ZUPT) aided pedestrian inertial navigation and Inertial Measurement Unit (IMU) performances. Angle Random Walk of gyroscopes and Velocity Random Walk of accelerometers in IMU, velocity measurement uncertainty during the stance phase, and the sampling frequency of IMU are studied and their effects on the overall navigation accuracy are analyzed. Numerical simulation of the ZUPT-aided navigation algorithm is conducted based on a generated pedestrian trajectory to verify the analytical results with the discrepancy less than 30%, showing fidelity of the results. In this study, a foot motion model was developed according to the ambulatory gait analysis as a basis of the numerical simulation. This study may serve as a benchmark for analysis of errors in pedestrian inertial navigation.
New preclinical models for angioimmunoblastic T-cell lymphoma: filling the GAP (2020)

Mouse models are essential to study and comprehend normal and malignant hematopoiesis. The ideal preclinical model should mimic closely the human malignancy. This means that these mice should recapitulate the clinical behavior of the human diseases such as cancer and therapeutic responses with high reproducibility. In addition, the genetic mutational status, the cell phenotype, the microenvironment of the tumor and the time until tumor development occurs, should be mimicked in a preclinical model. This has been particularly challenging for human angioimmunoblastic lymphoma (AITL), one of the most prominent forms of peripheral T-cell lymphomas. A complex network of interactions between AITL tumor cells and the various cells of the tumor microenvironment has impeded the study of AITL pathogenesis in vitro. Very recently, new mouse models that recapitulate faithfully the major features of human AITL disease have been developed. Here, we provide a summary of the pathology, the transcriptional profile and genetic and immune-phenotypic features of human AITL. In addition, we give an overview of preclinical models that recapitulate more or less faithfully human AITL characteristics and pathology. These recently engineered mouse models were essential in the evaluation of novel therapeutic agents for possible treatment of AITL, a malignancy in urgent need of new treatment options.
Minimum Power Operation of Cascade Inverter-Based Dynamic Voltage Restorer (2008)

This paper introduces a new method for sag mitigation in distribution networks by using the energy storage capability of a cascade inverter-type dynamic voltage restorer (DVR). A parametric analysis of the sag-control capability as a function of the load power factor is first conducted, and then used to design a new control strategy that optimizes the real energy injected by the DVR. The proposed mitigation method has the capability to mitigate longer duration sags while maintaining minimal capacitor energy storage. Special consideration is also given to the case when the injected voltage attains its ceiling. The analytical results are validated through electromagnetic transients' simulation of a cascade seven-level inverter used for sag control. Experimental results are presented to demonstrate the feasibility and the practicality of the proposed mitigation method.
METALORGANIC CHEMICAL VAPOR DEPOSITION : EXAMPLES OF THE INFLUENCE OF PRECURSOR STRUCTURE ON FILM PROPERTIES (1991)

The influence of precursor structure and reactivity on properties of compound semiconductors grown by metalorganic chemical vapor deposition (MOCVD) is discussed and illustrated with examples for growth of GaAs, ZnSe, and AlxGa1-xN. Gas-phase and surface reactions of organometallic arsenic compounds provide understanding of variation in carbon incorporation levels with precursor structure. Surface spectroscopy studies reveal the critical role of hydrogen-arsenic bonds in reducing carbon levels. MOCVD of ZnSe with different organoselenium compounds demonstrate that the growth rate behaves as expected from the Se-ligand bond strengths, but also that unexpected minor pathways can make a precursor unsuitable by causing increased carbon incorporation. Interactions between organometallic precursors mean that the structure of the precursors cannot be manipulated independently for the individual precursors, but must be considered in terms of the overall growth chemistry. The use of a single-source precursor, versus separate precursors for MOCVD of compound semiconductors is discussed and illustrated with data for the growth of AIN and GaN.
Production of intense isolated attosecond pulses for nonlinear XUV-XUV pump-probe experiments with 100 eV photons (2014)

Intense isolated attosecond pulses with &gt;100 eV photon energy are produced via high-order-harmonic generation using 80mJ sub-5 fs laser pulses. The generation of these attosecond pulses and their application to non-linear XUV-XUV pum-probe experiments is discussed.
