Nature and measurements of torque ripple of permanent-magnet adjustable-speed motors (1995)

Torque ripple of permanent-magnet motors can be classified into four types depending on the nature of their origin. The four types are pulsating torque, fluctuating torque, reluctance cogging torque, and inertia and mechanical system torque. Pulsating torques are inherently produced by the trapezoidal back-emf`s and trapezoidal currents used in certain permanent-magnet adjustable-speed motors. The torque ripples caused by pulsating torques may be reduced by purposely produced fluctuating counter torques. Air-gap torque measurements are conducted on a sample motor. Experimental results agree with theoretical expectations.
Exercise Reduces Inflammation and Oxidative Stress in Obesity-Related Liver Diseases (2013)

Exercise training benefits the management of obesity-related liver diseases independent of detectable weight reduction. Particularly, these effects seem to be acquired through an improvement in the hepatic inflammatory condition and its related oxidative stress levels.
The relevance of preferentially expressed antigen of melanoma (PRAME) as a marker of disease activity and prognosis in acute promyelocytic leukemia (2008)

Low PRAME expression defines a subgroup of patients with acute promyelocytic leukemia with a short relapse-free survival. This marker could be useful as a secondary marker for monitoring patients with acute promyelocytic leukemia.
Slow Strain Rate and Rising Step Load Hydrogen Embrittlement Testing of UNS N07718 (2016)

Abstract The influence of testing methods and microstructure on hydrogen embrittlement susceptibility of UNS(1) N07718 was assessed through slow strain rate (SSR) experiments and rising step load (RSL) testing performed in air and in a cathodic hydrogen charging test cell. The alloy was annealed and either peak-aged or over-aged to produce different strengths and precipitation conditions. The change in ductility, strength, and threshold stress intensity factor for crack growth due to hydrogen charging are compared. Over-aging resulted in superior SSR ductility ratios and higher threshold stress intensity factors compared to peak-aging. The better performance of the over-aged condition occurred despite more δ phase present at the grain boundaries, which indicates an influence of γ’ and γ” precipitation on hydrogen embrittlement resistance. Both conditions exhibited mixtures of intergranular and transgranular fracture in the embrittled region for both the SSR and RSL tests.
Joint data and power transfer optimization for energy harvesting wireless networks (2016)

Energy harvesting techniques emerge as a potential solution for prolonging the lifetime of the energy-constrained mobile wireless devices. In this paper, we focus on radio frequency (RF) energy harvesting for multiuser multicarrier mobile wireless networks. The mobile users are capable of harvesting energy from the dedicated subcarriers over which they are communicating with the base station in addition to harvesting ambient RF signals. We propose a joint data and energy transfer optimization framework for powering mobile wireless devices through RF energy harvesting while minimizing the overall power consumption. The proposed framework determines the optimal power resources that need to be allocated to meet data rate requirements of downlink and uplink communications. Simulations show that substantial power savings are achieved by allowing the ambient RF energy harvesting as well as by exploiting the different system parameters.
&lt;title&gt;Fiber optic distributed sensing systems for harsh aerospace environments&lt;/title&gt; (1999)

Seed Layer Etching, Thermal Reflow and Bonding of Cu-Sn Micro Bumps with $5\ \mu \mathrm{m}$ Diameters (2023)

Transient-liquid-phase (TLP) Cu-Sn bonding is an attractive method for fabrication of intra-chip connects in 3-D and chiplet applications due to the ease of manufacturing and low cost. With the continuous increase in the interconnect densities, it is highly desired to shrink the Cu-Sn bump diameters to <tex xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">$\mathbf{5}\ \boldsymbol{\mu} \mathbf{m}$</tex> or less from the current mainstream <tex xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">$\mathbf{20}\sim \mathbf{30}\ \boldsymbol{\mu} \mathbf{m}$</tex>. However, small Cu-Sn bumps shows significant difference from large ones because some surface related properties that are insignificant for large bumps become dominant for small ones. This paper reports the differences between bonding of large and small Cu-Sn bumps, such as surface oxidation and bump undercut, and proposes the methods to address these problems. By optimizing the bonding processes, TLP bonding of Cu-Sn bumps with a <tex xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">$\mathbf{5}\ \boldsymbol{\mu} \mathbf{m}$</tex> diameter has been successfully achieved.
A New Approach for Polymer-Free Coating with Paclitaxel Microparticles on Fully-Bioabsorbable Poly(l-Lactic Acid) Stent and Studies of Drug Release Behavior (2015)

A first clinically-used, fully-bioabsorbable poly(L-lactic acid) (PLLA) stent was coated with microcrystals of paclitaxel (PTX), antiproliferative agent through seeding and/or crystal growing technique to investigate the drug properties on the stent surface and drug release behavior from the stent. PTX particles subject to only seeding process was peeled off after stent compression, while less PTX was coated on the stent subject to only crystal growth without seeding. PLLA stent with both processes could stably maintain an increased amount of PTX on its surface. The maximum amount of initial release (10 μg/cm2) was found in the sample only with seeding, which decreased to 3 μg/cm2 or below after one week. Also in the PLLA stent only with crystal growth, release amount decreased after one week. In the PLLA stent with seeding and crystal growth, formation of needle-like PTX crystals on the surface resulted in decreased initial release and lower solubility after hydration in phosphate buffered solution compared to other types of stent with different procedures. It is suggested that both seeding and crystal growth are required for stable application of PTX on fully-bioabsorbable PLLA stent and needle-like crystals containing water have lower aqueous solubility resulting in decreased PTX release.
Evaluating the Accuracy of Vehicular Channel Models in a Large-Scale DSRC Test (2017)

Vehicle-to-vehicle channel characteristics differ significantly from those of conventional cellular channels, especially in terms of fading statistics due to varying environmental conditions, link types, vehicle types, and objects that result in complex propagation effects. Accurate modeling of the vehicular channel remains a complex challenge. In this paper, existing, common vehicular channel models (VCMs) are evaluated and compared to measurement data from the UMTRI large-scale Dedicated Short-Range Communications (DSRC) testbed involving nearly 3000 vehicles and conducted over several months around Ann Arbor, MI. While many VCMs can predict reasonably well the frequent packet error rates observed near Ann Arbor, they over-estimate inter-packet gap and under-estimate the likelihood of runs of consecutively and successfully received packets. The testbed environment shows significant fading (i.e., sub-Rayleigh) and/or shadowing effects that challenge the accuracy of traditional VCMs. Furthermore, despite 60% of the inter-vehicle paths being obstructed by items available using OpenStreetMap (OSM) geodata, a deterministic obstacle shadowing model that makes use of such geodata does not account for all shadowing effects. Evaluating vehicular channel models in terms of real-world, large-scale experiments helps researchers better understand actual behaviors and allows for the development of new and/or improved models that more accurately reflect reality.
Analysis of supported zirconocenes by x‐ray emission and absorption techniques (2004)

Abstract Metal contents in supported zirconocene catalysts were comparatively determined by x‐ray fluorescence spectroscopy and Rutherford backscattering spectrometry. A series of supported zirconocenes was prepared by grafting sequentially Cp 2 ZrCl 2 (Cp = cyclopentadienyl) and (nBuCp) 2 ZrCl 2 on to silica. The addition order and molar ratio of the two catalysts were varied. The grafted metal content was shown to be coherent between the two techniques and was between 0.37 and 0.53 wt% Zr/SiO 2 . The steric effect played by the ligand influences the final zirconocene grafted content. No influence of the grafting order was observed. Nevertheless, catalyst systems in which (nBuCp) 2 ZrCl 2 was either immobilized in the first place or at a higher molar ratio were shown to be more active in ethylene polymerization. Extended x‐ray absorption fine structure analysis in the Zr‐edge showed that systems bearing Cp 2 ZrCl 2 and (nBuCp) 2 ZrCl 2 in a 1:3 molar ratio afforded a more disoriented system. According to electron probe microanalysis, the metal distribution in the catalyst particle was more uniform than that resulting from the immobilization of solely (nBuCp) 2 ZrCl 2 on silica.

Quantitation of regional myocardial function during short-lived events with ultrasound imaging (2005)

Short-lived (tens through hundreds of milliseconds) cardiac motion events, such as post-systolic thickening, have diagnostic importance and are detectable by echocardiography. Selection and quantitative analysis of these events cannot be adequately done using conventional clinical measurements of heart function. We have developed an interactive tool using MATLAB (The MathWorks, Inc., Natick, MA) that allows the user to select events in time from graphs of available data including ECG, strain, left ventricular (LV) pressure, and the time derivative of the LV pressure trace. After selection of an event in time, the program calculates the area for that section of a pressure-strain loop, which is known to correlate to myocardial contraction work. Using the new tool, we present data from a canine model of prolonged (1-2 week) local myocardial ischemia. We found that following ischemia, a proportion of the loop area in the affected cardiac muscle takes place during a postejection phase. That is, the muscle contracts but during the postejection (post-systolic) phase and hence no longer contributes to ejecting blood to circulation.
An analysis of the energy efficiency of multi-threading on multi-core machines (2010)

Multi-core machines are said to provide high performance at low-energy cost via multi-threading. However, obtaining high performance at low-energy cost depends on the optimal usage of the platform. The experimental results show that executing a multi-threaded program with an optimal configuration can lead to significant gains: up to 38.1% reduction in power and 49.72% reduction in total energy. The paper reports on the importance of isolating the energy used by the idle system and considering just the energy used by the multi-threaded program to be able to evaluate the performance of multi-threading accurately. The experimental results also show that the concept that “power consumption is proportional to the cube of the frequency” is not general and does not apply to the scenario investigated. In the experiments presented, the power consumption was rather linear with Intel's mainstream Core Duo Quad microprocessor.
An approximate loop transfer recovery method for designing fixed-order compensators (1988)

A method for designing fixed-order dynamic compensators for multivariable time invariant linear systems is presented which is based on the minimization of a linear quadratic performance index. The present formulation is performed in an output feedback setting which uses an observer cononical form to represent the compensator dynamics. Techniques for penalizing the plant and compensator states and for selecting the distribution on initial conditions such that the loop transfer matrix approximates that of a full-state feedback design have been developed. The effectiveness of the method is demonstrated using the examples of the pointing of a flexible structure and a helicopter flight control problem.

Two-dimensional windowed Fourier frames for noise reduction in fringe pattern analysis (2005)

The two-dimensional continuous windowed Fourier transform has been shown to be effective for fringe pattern analysis in our previous work. In this paper, we first estimate the sampling intervals, using frame theory, to discretize the transform. Suitable sampling intervals are estimated as 1/x and 1/y, which is verified by simulations. Noise reduction using windowed Fourier frames is then investigated and compared with that using the orthogonal wavelet transform. Due to the coherence of its kernels and fringe patterns and its redundancy, windowed Fourier frames are able to reduce noise more effectively, which is verified by processing both simulated and experimental fringe patterns. The relative errors are reduced by half, in various simulations, from those with orthogonal wavelet filtering.
Complex motor behaviors in temporal lobe epilepsy (2005)

Complex motor behaviors differing from typical automatisms were found in 12 of 502 patients with temporal lobe epilepsy. Movements involved proximal limb segments (6) or body axis (6) and were often preceded by auras and followed by automatisms. Seven of 12 patients are seizure free after surgery. The other 5 patients declined surgery.

A study of noise phenomena in microwave components using an advanced noise measurement system (1997)

A novel 9 GHz measurement system with thermal noise limited sensitivity has been developed for studying the fluctuations in passive microwave components. The noise floor of the measurement system is flat at offset frequencies above 1 kHz and equal to -193 dBc/Hz. The developed system is capable of measuring the noise in the quietest microwave components in real time. We discuss the results of phase and amplitude noise measurements in precision voltage controlled phase shifters and attenuators. The first reliable experimental evidences regarding the intrinsic flicker phase noise in microwave isolators are also presented.
Validation of Unobtrusive Pressure Sensor Array for Central Sleep Apnea Screening (2012)

A new understanding about the role and importance of sleep in health combined with rapidly aging demographics presents opportunities for research and development of new approaches in sleep monitoring. As well, challenges with the current sleep-monitoring solution can be addressed by studying the suitability of new monitoring technologies. This paper presents a small-scale validation of the unobtrusive pressure sensor array compared with traditional polysomnography (PSG), for use as a central apnea (CA) screening tool. Algorithms developed for the pressure sensor array provided a very good detection of the CAs as compared to the gold-standard data for the six patients studied whose body-mass index was appropriate for the sensor. For the retained patients, the algorithm classified CA events with an average sensitivity of 87.6%, specificity of 99.9%, and Cohen's kappa value of 0.875. This work evaluates the ability of an algorithm applied to the unobtrusive pressure sensor array to detect CAs. The sensor array was compared to three other signals: 1) expert PSG interpreters; 2) inductance plethysmography (IP) bands alone; and 3) IP bands combined with an airflow or oxygen-saturation sensor. The impact of unobtrusive CA detection on an older adult's health could be in the areas of broadening of the access to sleep monitoring, longitudinal monitoring of the disease progression, and possibly providing information on the interaction between CA and other disease processes.
A graph-based approach for local and global panorama imaging in cystoscopy (2013)

Inspection of the urinary bladder with an endoscope (cystoscope) is the usual procedure for early detection of bladder cancer. The very limited field of view provided by the endoscope makes it challenging to ensure, that the interior bladder wall has been examined completely. Panorama imaging techniques can be used to assist the surgeon and provide a larger view field. Different approaches have been proposed, but generating a panorama image of the entire bladder from real patient data is still a challenging research topic. We propose a graph-based and hierarchical approach to assess this problem to first generate several local panorama images, followed by a global textured three-dimensional reconstruction of the organ. In this contribution, we address details of the first level of the approach including a graph-based algorithm to deal with the challenging condition of in-vivo data. This graph strategy gives rise to a robust relocalization strategy in case of tracking failure, an effective keyframe selection process as well as the concept of building locally optimized sub-maps, which lay the ground for a global optimization process. Our results show the successful application of the method to four in-vivo data sets.
Efficient Certified Defenses Against Patch Attacks on Image Classifiers (2021)

Adversarial patches pose a realistic threat model for physical world attacks on autonomous systems via their perception component. Autonomous systems in safety-critical domains such as automated driving should thus contain a fail-safe fallback component that combines certifiable robustness against patches with efficient inference while maintaining high performance on clean inputs. We propose BagCert, a novel combination of model architecture and certification procedure that allows efficient certification. We derive a loss that enables end-to-end optimization of certified robustness against patches of different sizes and locations. On CIFAR10, BagCert certifies 10.000 examples in 43 seconds on a single GPU and obtains 86% clean and 60% certified accuracy against 5x5 patches.

Ectopic Recombination between Ty Elements in <i>Saccharomyces cerevisiae</i> Is Not Induced by DNA Damage (1992)

Mitotic recombination is increased when cells are treated with a variety of physical and chemical agents that cause damage to their DNA. We show here, using Saccharomyces cerevisiae strains that carry marked Ty elements, that recombination between members of this family of retrotransposons is not increased by UV irradiation or by treatment with the radiomimetic drug methyl methanesulfonate. Both ectopic recombination and mutation events were elevated by these agents for non-Ty sequences in the same strain. We discuss possible mechanisms that can prevent the induction of recombination between Ty elements.
Using Ambient Ion Beams to Write Nanostructured Patterns for Surface Enhanced Raman Spectroscopy (2014)

Abstract Electrolytic spray deposition was used to pattern surfaces with 2D metallic nanostructures. Spots that contain silver nanoparticles (AgNP) were created by landing solvated silver ions at desired locations using electrically floated masks to focus the metal ions to an area as little as 20 μm in diameter. The AgNPs formed are unprotected and their aggregates can be used for surface‐enhanced Raman spectroscopy (SERS). The morphology and SERS activity of the NP structures were controlled by the surface coverage of landed silver ions. The NP structures created could be used as substrates onto which SERS samples were deposited or prepared directly on top of predeposited samples of interest. The evenly distributed hot spots in the micron‐sized aggregates had an average SERS enhancement factor of 10 8 . The surfaces showed SERS activity when using lasers of different wavelengths (532, 633, and 785 nm) and were stable in air.
Surface-Stress Induced Embrittlement of Metals (2021)

Environment-assisted fracture phenomena in metals are usually associated with surface energy reduction due to an adsorbed film. Here we demonstrate a unique embrittlement effect in Al that is instead mediated by surface stress, induced by an adsorbed organic monolayer. Atomistic simulations show that the adsorbate carbon-chain length <i>l</i><sub>c</sub> controls the surface stress via van der Waals forces, being compressive for <i>l</i><sub>c</sub> < 8 and tensile otherwise. For <i>l</i><sub>c</sub> > 8, we demonstrate experimentally that the nanoscale film causes a ductile-to-brittle transition on the macroscale. Concomitant with this transition is a nearly 85% reduction in deformation forces. Additional simulations reveal that the microscopic mechanism for the embrittlement is via suppression of dislocation emission at incipient crack-tips. In addition to challenging long-held views on environment-assisted fracture, our findings pertaining to surface-stress induced embrittlement suggest profitable utility in manufacturing processes such as machining and comminution.
Lung nodule segmentation in chest computed tomography using a novel background estimation method. (2016)
