Gait mechanics 2 years after anterior cruciate ligament reconstruction are associated with longer‐term changes in patient‐reported outcomes (2016)

This study tested the hypothesis that side-to-side differences in knee gait mechanics 2 years after anterior cruciate ligament (ACL) reconstruction are associated with long-term (∼8 years post-reconstruction) changes in patient-reported outcome scores. Sixteen subjects (5 males; age: 29.1 ± 7.1 years) with primary unilateral ACL reconstruction were gait tested at baseline (2.2 ± 0.3 years post-ACL reconstruction) and filled out KOOS and Lysholm surveys. At long-term follow-up (7.7 ± 0.7 years post-ACL reconstruction), the same subjects completed KOOS and Lysholm surveys. Pearson correlation coefficients assessed relationships between side-to-side differences in kinematics and kinetics at baseline and changes in Lysholm and KOOS Pain/QOL scores from 2 to 8 years post-ACL reconstruction. Significant associations were seen between greater average varus rotation (Lysholm: R = -0.654, p = 0.006) and less anterior femoral displacement (Lysholm: R = 0.578, p = 0.019) during stance of the ACL reconstructed knee versus the contralateral knee at baseline and worse follow-up outcome scores. Significant associations were seen between greater peak knee flexion moment (KOOS Pain: R = -0.572, p = 0.026; KOOS QOL: R = -0.636, p = 0.011), peak knee adduction moment (Lysholm: R = -0.582, p = 0.018; KOOS Pain: R = -0.742, p = 0.002; KOOS QOL: R = -0.551, p = 0.033), and peak internal rotation moment (Lysholm: R = 0.525, p = 0.037; KOOS Pain: R = 0.815, p < 0.001; KOOS QOL: R = 0.777, p = 0.001) in the ACL reconstructed knee at baseline with worse follow-up outcomes. The results of this study support the hypotheses that early changes in gait mechanics following ACL reconstruction are associated with longer-term clinical changes in patient-reported outcomes, suggesting that biomechanical markers obtained as early as 2 years after ACL reconstruction may be useful to understand clinical outcomes in this population. © 2016 Orthopaedic Research Society.

Constrained coalitional games and networks of autonomous agents (2008)

We develop a unifying analytical and optimization- based framework for the design, operation and performance evaluation of networks of dynamic autonomous agents. The fundamental view is that agents in such a network are dynamic entities that collaborate because via collaboration they can accomplish objectives and goals much better than working alone, or even accomplish objectives that they cannot achieve alone at all. Yet the benefits derived from such collaboration require some costs (e.g. communications), or equivalently, the collaboration is subject to constraints. Understanding and quantifying this tradeoff between the benefits vs the costs of collaboration, leads to new methods that can be used to analyze, design and control/operate networks of agents. Although the inspiration for the framework comes from social and economic networks, the fundamental ideas and in particular the methodology of dynamic constrained coalitional games (DCCG) can unify many concepts and algorithms for networks in various areas: social networks, communication networks, sensor networks, economic networks, biological networks, physics networks. We then analyze a specific instance of such tradeoffs arising in the design of security aware network protocols. We extend network utility maximization (NUM) so as to encompass security metrics such as "trust". The trust values assigned to nodes are based on interaction history and community-based monitoring. The effect of these trust values on the resulting protocols is that in routing and media access scheduling node trustworthiness is automatically considered and used. We develop a distributed algorithm for the joint physical-MAC-routing protocol design. Our extension to NUM with security concerns leads to resilient networks.
From Fundamental Understanding to Engineering Design of High‐Performance Thick Electrodes for Scalable Energy‐Storage Systems (2021)

The ever-growing needs for renewable energy demand the pursuit of batteries with higher energy/power output. A thick electrode design is considered as a promising solution for high-energy batteries due to the minimized inactive material ratio at the device level. Most of the current research focuses on pushing the electrode thickness to a maximum limit; however, very few of them thoroughly analyze the effect of electrode thickness on cell-level energy densities as well as the balance between energy and power density. Here, a realistic assessment of the combined effect of electrode thickness with other key design parameters is provided, such as active material fraction and electrode porosity, which affect the cell-level energy/power densities of lithium-LiNi<sub>0.6</sub> Mn<sub>0.2</sub> Co<sub>0.2</sub> O<sub>2</sub> (Li-NMC622) and lithium-sulfur (Li-S) cells as two model battery systems, is provided. Based on the state-of-the-art lithium batteries, key research targets are quantified to achieve 500 Wh kg<sup>-1</sup> /800 Wh L<sup>-1</sup> cell-level energy densities and strategies are elaborated to simultaneously enhance energy/power output. Furthermore, the remaining challenges are highlighted toward realizing scalable high-energy/power energy-storage systems.
DC characteristics of OMVPE-grown N-p-n InGaP/InGaAsN DHBTs (2000)

The authors demonstrate, for the first time, a functional N-p-n heterojunction bipolar transistor using a novel material, InGaAsN, with a bandgap energy of 1.2eV as the p-type base layer. A 300{angstrom}-thick In{sub x}Ga{sub 1-x}As graded layer was introduced to reduce the conduction band offset at the p-type InGaAsN base and n-type GaAs collector junction. For an emitter size of 500 {mu}m{sup 2}, a peak current gain of 5.3 has been achieved.
Robotic Simulation of the Docking and Path Following of an Autonomous Small Grain Harvesting System (2003)

Researchers around the world have focused on autonomous agriculture, with systemsencompassing greenhouse, orchard, field and other applications. Research has shown the potential and abilityof the technology to allow a vehicle or selection of vehicles to follow a specified task. In this study, one aspectof the problem, that of operating a tractor-cart combination in conjunction with a small-grain combine harvester,was investigated. The tractor-cart combination and combine harvester application was selected because of thehigh fatigue and long duration aspects of the problem. The system was simulated using two iRobot MagellanPro robots in an indoor environment. The differential drive robots were software constrained to match thedynamics of typical agricultural vehicles. Position feedback was supplied by odometry. A small towed trailerwas added to one robot to simulate a typical grain cart.

Inoculation Effect in Prevention of Increased Verbal Aggression in Schools (2004)

This paper presents an argument for the use of intervention programs as inoculation agents in adolescents' social behavior, specifically the prevention of abusive and antisocial verbal aggression. The theoretical substance of the intervention is social-cognitive and eclectic, borrowing from several strategies known to be effective. The bridge between theory and curriculum is an inoculation-like process. Inoculation is not a strategy to change beliefs but rather to reinforce prosocial attitudes and assist students in overcoming influences that might lessen their prosocial stance. Results must include a control group to assess the effect of inoculation.
On The Detection Of Footprints From Strong Electron Acceleration In High-Intensity Laser Fields, Including The Unruh Effect (2010)

The ultra‐high fields of high‐power short‐pulse lasers are expected to contribute to understanding fundamental properties of the quantum vacuum and quantum theory in very strong fields. For example, the neutral QED vacuum breaks down at the Schwinger field strength of 1.3 1018 V/m, where a virtual e+e− pair gains its rest mass energy over a Compton wavelength and materializes as a real pair. At such an ultra‐high field strength, an electron experiences an acceleration of as = 2 1028 g and hence fundamental phenomena such as the long predicted Unruh effect start to play a role. The Unruh effect implies that the accelerated electron experiences the vacuum as a thermal bath with the Unruh temperature. In its accelerated frame the electron scatters photons off the thermal bath, corresponding to the emission of an entangled pair of photons in the laboratory frame. In upcoming experiments with intense accelerating fields, we will encounter a set of opportunities to experimentally study the radiation from electrons under extreme fields. Even before the Unruh radiation detection, we should run into the copious Larmor radiation. The detection of Larmor radiation and its characterization themselves have never been experimentally carried out to the best of our knowledge, and thus this amounts to a first serious study of physics at extreme acceleration. For example, we can study radiation damping effects like the Landau‐Lifshitz radiation. Furthermore, the experiment should be able to confirm or disprove whether the Larmor and Landau‐Lifshitz radiation components may be enhanced by a collective (N2) radiation, if a tightly clumped cluster of electrons is accelerated. The technique of laser driven dense electron sheet formation by irradiating a thin DLC foil target should provide such a coherent electron cluster with a very high density. If and when such mildly relativistic electron sheets are realized, a counterpropagating second laser can interact with them coherently. Under these conditions enhanced Larmor and Unruh radiation signals may be observed.Detection of the Unruh photons (together with its competing radiation components) is envisaged via Compton polarimetry in a novel highly granular 2D‐segmented position‐sensitive germanium detector.
High density magnetic recording head slider for small rigid disk (1987)

The new negative pressure slider called NNP slider has been developed for the attainment of high density recording in magnetic disk drives. The NNP slider has high stiffness and a very small flying height of 0.1 μm independent of the disk velocity. And in using an actual disk(a sputtered disk), the NNP slider can follow the vertical run-out of the disk and fly stably, even though the flying height may fluctuate due to the undulation or roughness of the disk. Therefore, crash phenomena do not occur. The stable flying of the NNP slider can bring out the best properties of the sputtered disks.

Experimental and theoretical investigations of parameters controlling line profiles in electron-beam lithography (1981)

An experimental and theoretical investigation of the more important parameters which affect the developed profile shape in electron-beam lithography is described. The theoretical approach is based on a Monte Carlo method of simulating electron scattering in the substrate to calculate the energy dissipation in the electron resist layer for a scanned electron beam. The current distribution in the beam is taken into account with a separate convolution procedure. The developed profile shape is obtained with a threshold solubility model which predicts a threshold energy density of 6.58 × 1021 eV/cm3. A development simulation using the string method is used to predict the profile shape when the development process becomes a significant factor at a resist thickness of about 0.7μm. Finally the proximity effect is investigated by means of adjacent line experiments and compared with the predictions of the threshold solubility model.
Underlay multi-hop cognitive networks with orthogonal access (2015)

Stochastic algorithms to allocate resources across different layers in an underlay multi-hop cognitive radio with primary and secondary users are presented. The algorithms aim to maximize the utility of the secondary users, while adhering to average interfering power constraints and accounting for the presence of imperfections in the state information. Interference among secondary users is modeled using a binary conflict graph, so that close-by secondary devices cannot transmit simultaneously. The optimal resource allocation dictates the power transmitted by each user, the rates at the transport, network and physical level, and the links to be activated. The design is casted as a nonlinear constrained optimization, and the solution is obtained using stochastic dual decomposition. Nu- merical experiments validate the theoretical claims.
Synthesis and characterization of novel rigid two‐photon absorbing polymers (2005)

Abstract Two‐photon absorbing polymers with alternating fluorenyl units as a π‐conjugated bridge and bisbenzothiazole or thiazolothiazole as electron‐acceptors were synthesized and characterized by IR, elemental analysis, absorption and fluorescence spectroscopy, and thermogravimetric analysis (TGA). Improvement on the solubility was observed in comparison with their phenyl based analogies. The linear absorption and emission spectra were recorded and high fluorescence quantum yields were found. Relatively large two‐photon absorption cross‐section per repeat unit (420 GM) were measured under fs‐pulsed laser excitation. Copyright © 2005 John Wiley &amp; Sons, Ltd.
Effects of propagation through atmospheric turbulence on photon statistics (2004)

The theory of the photon statistics of a beam propagated over a horizontal path in air is described and applied to the counting distribution and fade probability for weak laser pulses. Good agreement is obtained between theory and experiment for values of the refractive-index structure constant within an expected range and for various simplifying assumptions, including the assumption of a log-normal distribution for the fluctuations of the mean photon number due to atmospheric turbulence.

Electrically detectable surface plasmon resonance sensor by combining a gold grating and a silicon photodiode (2018)

We propose an electrically detectable surface plasmon resonance sensor in a liquid consisting of a Au grating and a silicon p+n photodiode. The surface plasmon resonance (SPR) was excited on the Au grating, affecting the photovoltaic signal of the photodiode under the grating. The SPR signal was thus measured by obtaining the electrical signal without reflection measurements and a polarizer. The SPR conditions were clearly measured with our proposed sensor. It was verified that the SPR condition could also be measured without polarizing the incident light. The dielectric constant of water was determined using the proposed sensor.

Induction of Drug‐metabolizing Enzymes and Transporters in Human Bronchial Epithelial Cells by Beclomethasone Dipropionate (2004)

Inhaled steroids are the most potent anti-inflammatory therapy commonly used in bronchial asthma. There are, however, a small number of asthmatic patients who do not respond to inhaled steroid-treatment. The stimulation of metabolism and excretion of inhaled drugs at bronchial tissues might lead to a decrease in the effect of the drugs, although the molecular mechanism of this resistance is unclear. In this study, we found that beclomethasone dipropionate (BDP) stimulated the expression of mRNAs for uridine 5'-diphosphate glucuronosyl transferase 2B4 and 2B11, and transporters such as multidrug resistance P-glycoprotein, multidrug resistance-associated protein 1 and 2 in cultured bronchial epithelial cells. It is possible that the individual differences of expression of drug metabolizing enzymes and transporters and their enhancement with BDP are implicated in the individual differences of reactivity over steroid medical treatment.
Invertible motion blur in video (2009)

We show that motion blur in successive video frames is invertible even if the point-spread function (PSF) due to motion smear in a single photo is non-invertible. Blurred photos exhibit nulls (zeros) in the frequency transform of the PSF, leading to an ill-posed deconvolution. Hardware solutions to avoid this require specialized devices such as the coded exposure camera or accelerating sensor motion. We employ ordinary video cameras and introduce the notion of null-filling along with joint-invertibility of multiple blur-functions. The key idea is to record the same object with varying PSFs, so that the nulls in the frequency component of one frame can be filled by other frames. The combined frequency transform becomes null-free, making deblurring well-posed. We achieve jointly-invertible blur simply by changing the exposure time of successive frames. We address the problem of automatic deblurring of objects moving with constant velocity by solving the four critical components: preservation of all spatial frequencies, segmentation of moving parts, motion estimation of moving parts, and non-degradation of the static parts of the scene. We demonstrate several challenging cases of object motion blur including textured backgrounds and partial occluders.
Design and Optimization of an Inverter for a One-Megawatt Ultra-Light Motor Drive (2023)

View Video Presentation: https://doi.org/10.2514/6.2023-4161.vid This paper presents the design and optimization of a 1-MW inverter for a high-speed, high-specific-power motor drive. The proposed inverter consists of ten 100-kW inverter sets distributed around the periphery of the machine to drive ten separate sets of three-phase open-ended windings. Each inverter set consists of three single-phase full-bridge inverters each of which drives an open-ended phase winding. The use of three single-phase full-bridge inverters for each inverter set yields an improved specific power as compared to either the three-phase bridge inverter or the active neutral-point clamped (ANPC) inverter in the target application. The proposed inverter system is co-designed and co-optimized with a 1-MW permanent magnet machine and associated thermal management system. Experimental results demonstrating the performance of a 100-kW inverter set are provided. The air-cooled inverter set operates at 720 Vdc, 73.5 Aac,rms per phase and 80 kHz device switching frequency, and achieves 53.4 kW/kg specific power and > 98% efficiency.
