Realising Edge Analytics for Early Prediction of Readmission: A Case Study (2020)

The post-discharge support is increasingly suggested for stroke patients to be discharged earlier and start rehabilitation at home. Considering that stroke patients usually have a high chance of recurrence, a good prognostic program is essential to improve diagnostic capabilities while reducing readmission rate to further save medical sources. In this context, various machine learning methods have been leveraged to obtain diagnostic findings and guide further treatments. However, those approaches mainly focus on performing analysis using a single data source obtained from the hospital, which could ignore the information complementarity between different groups of features and several subtle and discrete differences of physical interpretation among them. In this paper, we propose an Edge-based system design for post-stroke surveillance and warning prediction, called PSMART (Post-Stroke Mobile Auxiliary Rudiment Treatment), for processing enriched pathogenic factors of ischemic stroke from multi-sensors (views) to make readmission warning predictions. Our approach can considerably enrich the distinctive features from raw data, as well as exploit the consistency and complementary proprieties of different views, leading to better learning results. We evaluate the performance of the proposed approach on a real-world dataset, and the accuracy can reach up to 98.98%. Moreover, experiment results also show that our proposed approach can provide better accuracy when compared to the single-view ones.
Extended Kalman Filter Based Resilient Formation Tracking Control of Multiple Unmanned Vehicles via Game-Theoretical Reinforcement Learning (2023)

In this paper, we discuss the resilient formation tracking control problem of multiple unmanned vehicles (MUV). A dynamic leader-follower distributed control structure is utilized to optimize the performance of the formation tracking. For the follower of the MUV, the leader is a cooperative unmanned vehicle, and the target of formation tracking is a non-cooperative unmanned vehicle with a nonlinear trajectory. Therefore, an extended Kalman filter (EKF) observer is designed to estimate the state of the target. Then the leader of the MUV is adjusted dynamically according to the state of the target. In order to describe the interactions between the follower and dynamic leader, a Stackelberg game model is constructed to handle the hierarchical decision problems. At the lower layer, each follower responds by observing the leader's strategy, and the potential game is used to prove a Nash equilibrium among all followers. At the upper layer, the dynamic leader makes decisions depending on the response of all followers to reaching the Stackelberg equilibrium. Moreover, the Stackelberg-Nash equilibrium of the designed game theoretical model is proven. A novel reinforcement learning-based algorithm is designed to achieve the Stackelberg-Nash equilibrium of the game. Finally, the effectiveness of the method is verified by a variety of formation tracking simulation experiments.
Noncontrast myocardial T1 mapping using cardiovascular magnetic resonance for iron overload (2014)

Myocardial T1 mapping is an alternative method for cardiac iron quantification. T1 mapping shows the potential for improved detection of mild iron loading. The superior reproducibility of T1 has potential implications for clinical trial design and therapeutic monitoring.
Article comprising a semiconducting material (2023)

Single crystals of the new semiconducting oxychalcogenide phase were synthesized using a novel crystal growth method. The crystals had low defects and homogeneous composition as characterized by single crystal X-ray diffraction and scanning electron microscopy, respectively. Heat capacity and resistivity measurements were in agreement with the calculated band structure calculations indicating semiconductivity, with a band gap of about 3 eV.

Long-Term Continuous-Flow Biventricular Support in a 63-Year-Old Woman (2018)

We describe the successful use of long-term biventricular continuous-flow mechanical circulatory support as a bridge to transplantation in a small-framed 63-year-old woman with long-standing nonischemic cardiomyopathy. After placement of a left-sided HeartWare HVAD, persistent right-sided heart failure necessitated implantation of a second HeartWare device for long-term right ventricular support. After 262 days, the patient underwent successful orthotopic heart transplantation and was discharged from the hospital. This report indicates the feasibility of biventricular device support in older patients of relatively small stature, and our results may encourage others to consider this therapy in similar patient populations.
ESTIMATION OF RANDOM BENDING STRAIN USING A SCANNING LASER VIBROMETER (1993)

Results are presented which were obtained from vibration measurements at discrete locations on a randomly excited structure to estimate the power spectral density of bending strain. The technique is intended to be applied using a scanning laser vibrometer to allow a non-contacting measurement of random bending strain over the surface of a structure. The experimental setup is described along with the data analysis procedure. The results presented here indicate that the method is practical and can lead to reliable estimates.
Tungsten Carbide-Cobalt Coatings for Industrial Applications (2000)

Abstract This paper compares the coating characteristics of two HVOF processes: air-cooled converging-nozzle Diamond Jet (DJ) spraying and Hybrid 2600 air/water-cooled converging/diverging technology. WC-Co coatings were deposited on steel substrates using different combinations of spray parameters, gas flow ratios, and cooling gas types. The coatings were then examined and tested to determine the extent to which microstructure, hardness, surface roughness, wear resistance, and deposition efficiency can be controlled. In addition to investigating process relationships, the paper also addresses the issues of practicality and cost.
HiSIM: hierarchical interconnect-centric circuit simulator (2005)

To ensure the power and signal integrity of modern VLSI circuits, it is crucial to analyze huge amount of nonlinear devices together with enormous interconnect and even substrate parasitics to achieve the required accuracy. Neither traditional circuit simulation engines such as SPICE nor switch-level timing analysis algorithms are equipped to handle such a tremendous challenge in both efficiency and accuracy. We establish a solid framework that simultaneously takes advantage of a hierarchical nonlinear circuit simulation algorithm and an advanced large-scale linear circuit simulation method using a new predictor-corrector algorithm. Under solid convergence and stability guarantees, our simulator, HiSIM, a hierarchical interconnect-centric circuit simulator, is capable of handling the post-layout RLKC power and signal integrity analysis task efficiently and accurately. Experimental results demonstrate over 180X speed up over the conventional flat simulation method with SPICE-level accuracy.
Exposure Systems (2010)

Before getting into imaging theory and practice, I would like to present exposure systems so that readers are better able to comprehend the abstract concepts in Chapters 3 and 4. An exposure system replicates the mask image to an aerial image in order to expose the photoresist layer on a wafer. After development, this resist image is used as an etch, implant, plating, or lift-off mask for pattern transfer to a thin-film layer on the wafer. There are different systems that can perform the replication function. When the feature size was in the 2- to 5-&#956;m regime, and the budget for semiconductor manufacturing was low, the aerial image in the 10- to 20-&#956;m proximity of the mask sufficiently produced a useable resist image, maintaining feature size and placement control. Below 2 &#956;m, infidelity of the aerial image, defect generation, and alignment viewing difficulties drove the bulk of exposure systems to 1X full-wafer projection printing. The field size of full-wafer systems grew with wafers from 50 to 125 mm in diameter. The ever-increasing wafer size and reducing feature size - together with the associated requirement in feature-size control and overlay accuracy - drove exposure systems to reduction step-and-repeat. Further increases in field size and a reduction in feature size, as well as difficulties in containing the 1X mask making within the total feature size control and overlay accuracy budgets, made it necessary to use reduction step-and-scan systems. This chapter describes proximity and projection-printing systems, full-wafer, step-and-repeat, and step-and-scan systems. The significance of reduction imaging is also analyzed.
Abstract 12562: Prasugrel May Be Associated With All-Cause Mortality Benefit in Patients on Chronic Dialysis (2021)

Introduction: Although prasugrel has been shown to be more effective over other P2Y12 inhibitors (P2Y12-I) in the general population, it remains unclear whether it is also superior in reducing all-cause death in patients on chronic dialysis (ESKD). Methods: This longitudinal analysis included Medicare patients with ESKD on P2Y12-I from the U.S. Renal Data System registry between 2011-2015. Patients were followed from receipt of new prescription until death or censoring. The primary outcome was all-cause death, and the secondary outcome was CV death, as ascertained from the registry. Survival analysis was performed after propensity matching. Results: Our analysis included 44,619 ESKD patients on P2Y12 inhibitors - 95% received clopidogrel (n= 42,523), 3% received prasugrel (n = 1,205), and 2% received ticagrelor (n = 891). During a median follow up of 1 year, there were 2,555 (30.7%), 1,370 (31.1%), and 404 (23.0%) deaths in the prasugrel-clopidogrel, the ticagrelor-clopidogrel, and the prasugrel-ticagrelor matched cohorts, respectively. Similarly, there were 1,266 (15.2%), 667 (15.1%) and 210 (11.9%) CV-deaths in the three cohorts respectively. Prasugrel vs. clopidogrel was associated with reduced risk for death (HR 0.80; 95% CI: 0.70, 0.90). Similar findings were noted when compared to ticagrelor (HR 0.75; 95% CI: 0.57, 0.98). Prasugrel was also associated with a borderline reduced risk for CV-death when compared with clopidogrel (HR 0.85; 95% CI: 0.72, 1.01) and ticagrelor (HR 0.80; 95% CI: 0.60, 1.07). Conclusion: Our findings suggest a benefit in reduction of all-cause death, possibly by reducing CV-death with use of prasugrel over other P2Y12-I in patients on chronic dialysis. Since these results could be limited due to residual confounding, future trials should investigate whether prasugrel is superior to other P2Y12-Is in reducing all-cause death and CV-death among patients on chronic dialysis.
Interactive Decoding of a Broadcast Message (2003)

We develop communication strategies for the rate-constrained interactive decoding of a message broadcast to a group of interested users. This situation diers from the relay channel in that all users are interested in the transmitted message, and from the broadcast channel because no user can decode on its own. We focus on two-user scenarios, and describe a baseline strategy that uses ideas of coding with decoder side information. One user acts initially as a relay for the other. That other user then decodes the message and sends back random parity bits, enabling the first user to decode. We show how to improve on this scheme’s performance through a conversation consisting of multiple rounds of discussion. While there are now more messages, each message is shorter, lowering the overall rate of the conversation. Such multi-round conversations can be more ecient because earlier messages serve as side information known at both encoder and decoder. We illustrate these ideas for binary erasure channels. We show that multi-round conversations can decode using less overall rate than is possible with the single-round scheme.
Glycerol Oxidation Using Gold-Containing Catalysts (2015)

Glycerol is an important byproduct of biodiesel production, and it is produced in significant amounts by transesterification of triglycerides with methanol. Due to the highly functionalized nature of glycerol, it is an important biochemical that can be utilized as a platform chemical for the production of high-added-value products. At present, research groups in academia and industry are exploring potential direct processes for the synthesis of useful potential chemicals using catalytic processes. Over the last 10 years, there has been huge development of potential catalytic processes using glycerol as the platform chemical. One of the most common processes investigated so far is the catalytic oxidation of glycerol at mild conditions for the formation of valuable oxygenated compounds used in the chemical and pharmaceutical industry. The major challenges associated with the selective oxidation of glycerol are (i) the control of selectivity to the desired products, (ii) high activity and resistance to poisoning, and (iii) minimizing the usage of alkaline conditions. To address these challenges, the most common catalysts used for the oxidation of glycerol are based on supported metal nanoparticles. The first significant breakthrough was the successful utilization of supported gold nanoparticles for improving the selectivity to specific products, and the second was the utilization of supported bimetallic nanoparticles based on gold, palladium, and platinum for improving activity and controlling the selectivity to the desired products. Moreover, the utilization of base-free reaction conditions for the catalytic oxidation of glycerol has unlocked new pathways for the production of free-base products, which facilitates potential industrial application. The advantages of using gold-based catalysts are the improvement of the catalyst lifetime, stability, and reusability, which are key factors for potential commercialization. In this Account, we discuss the advantages of the using supported gold-based nanoparticles, preparation methods for achieving highly active gold-based catalysts, and parameters such as particle size, morphology of the bimetallic particle, and metal-support interactions, which can influence activity and selectivity to the desired products.
Hydrogen Absorption Behavior and Absorbed Hydrogen Trapping Sites in Rolling Contact Fatigue (2021)

Hydrogen absorption behavior and microstructural change of carburized JIS SCr420 steels containing different amounts of retained austenite in rolling contact fatigue were investigated. The thermal desorption analysis confirmed hydrogen desorption at the second-peak between 423 and 623 K after rolling contact fatigue. The hydrogen concentration at the second-peak increased with number of cycles in the rolling contact. This increment was larger when using the steel with a higher amount of retained austenite before the fatigue test. The increment of hydrogen concentration at the second-peak was large even when the introduction of new dislocations due to the martensitic transformation of retained austenite was considered to be small. The activation energies of desorption for the second-peak hydrogen were calculated to be 50.6 kJ·mol−1 for the steel with 10.4% retained austenite and 55.8 kJ·mol−1 for the steel with 4.9% retained austenite. The activation energies of cathodically charged 0.8%C steels with 10.9% and 6.0% retained austenite, simulating carburized layer before the test, were 36.2 and 42.2 kJ·mol−1, respectively. This means that the activation energy of hydrogen desorption increased during rolling contact. The absorbed hydrogen during the rolling contact fatigue was likely trapped in more stable trapping sites related to the retained austenite which were formed under cyclic stress.
Performance and pulse shortening effects in a 200-kV PASOTRON/sup TM/ HPM source (1998)

The PASOTRON/sup TM/ is a unique, high-power microwave source that uses a long-pulse (/spl les/100 /spl mu/s) plasma-cathode electron-gun and plasma-filled slow-wave structure (SWS) to produce high-energy microwave pulses. The device utilizes no externally-produced magnetic fields; relying on a beam-generated plasma channel in the SWS to transport the beam. Peak powers of up to 5 MW were previously reported in C-band using a rippled-wall waveguide SWS. Scaling experiments indicated that increasing the beam voltage above the 90 kV C-band operation produces significantly higher peak powers. We report results from an L-band PASOTRON/sup TM/ BWO designed to operate at 200 kV. The plasma-cathode E-gun built for this device generated beams with voltages of up to 225 kV and currents in excess of 1 kA for pulse lengths of up to 200 /spl mu/s. The L-band PASOTRON/sup TM/ BWO produced 10-20 MW of peak power in the TM/sub 01/ mode, which was converted in the output to a TE/sub 11/ mode with fixed polarization. The PASOTRON/sup TM/ also directly produced TE-mode radiation in the 5-10 MW power range with a rotating output polarization, the rate of which can be controlled externally. The peak power and poise width was limited by the stability of the plasma channel at high peak powers and excessive plasma generation in the SWS during the long pulse length.
An intuitive framework for understanding changes in evolving data streams (2003)

Many organizations today store large streams of transactional data in real time. This data can often show important changes in trends over time. In many commercial applications, it may be valuable to provide the user with an understanding of the nature of changes occuring over time in the data stream. In this paper, we discuss the process of analysing the significant changes and trends in data streams in a way which is understandable, intuitive and user-friendly.
Watermarking the Outputs of Structured Prediction with an application in Statistical Machine Translation. (2011)

We propose a general method to watermark and probabilistically identify the structured outputs of machine learning algorithms. Our method is robust to local editing operations and provides well defined trade-offs between the ability to identify algorithm outputs and the quality of the watermarked output. Unlike previous work in the field, our approach does not rely on controlling the inputs to the algorithm and provides probabilistic guarantees on the ability to identify collections of results from one’s own algorithm. We present an application in statistical machine translation, where machine translated output is watermarked at minimal loss in translation quality and detected with high recall. and human generated translations are currently both found extensively on the web, with no automatic way of distinguishing between them. Algorithms that mine data from the web (Uszkoreit et al., 2010), with the goal of learning to simulate human behavior, will now learn models from this contaminated and potentially selfgenerated data, reinforcing the errors committed by earlier versions of the algorithm. It is beneficial to be able to identify a set of encountered structured results as having been generated by one’s own algorithm, with the purpose of filtering such results when building new models. Problem Statement: We define a structured result of a query q as r = {z1 · · · zL} where the order and identity of elements zi are important to the quality of the result r. The structural aspect of the result implies the existence of alter-1
Lung endothelial heparan sulfates mediate cationic peptide-induced barrier dysfunction: a new role for the glycocalyx (2003)

The endothelial glycocalyx is believed to play a major role in microvascular permeability. We tested the hypothesis that specific components of the glycocalyx, via cytoskeletal-mediated signaling, actively participate in barrier regulation. With the use of polymers of arginine and lysine as a model of neutrophil-derived inflammatory cationic proteins, we determined size- and dose-dependent responses of cultured bovine lung microvascular endothelial cell permeability as assessed by transendothelial electrical resistance (TER). Polymers of arginine and lysine >11 kDa produced maximal barrier dysfunction as demonstrated by a 70% decrease in TER. Monomers of l-arginine and l-lysine did not alter barrier function, suggesting a cross-linking requirement of cell surface "receptors". To test the hypothesis that glycosaminoglycans (GAGs) are candidate receptors for this response, we used highly selective enzymes to remove specific GAGs before polyarginine (PA) treatment and examined the effect on TER. Heparinase III attenuated PA-induced barrier dysfunction by 50%, whereas heparinase I had no effect. To link changes in barrier function with structural alterations, we examined actin organization and syndecan localization after PA. PA induced actin stress fiber formation and clustering of syndecan-1 and syndecan-4, which were significantly attenuated by heparinase III. PA-induced cytoskeletal rearrangement and barrier function did not involve myosin light chain kinase (MLCK) or p38 MAPK, as ML-7, a specific MLCK inhibitor, or SB-20358, a p38 MAPK inhibitor, did not alter PA-induced barrier dysfunction. In summary, lung endothelial cell heparan sulfate proteoglycans are key participants in inflammatory cationic peptide-induced signaling that links cytoskeletal reorganization with subsequent barrier dysfunction.
Altered activation of the tibialis anterior in individuals with Pompe disease: Implications for motor unit dysfunction (2014)

These results provide evidence that LOPD individuals have an altered activation pattern of the TA during maximal contractions. The observed activation pattern may reflect impairments in voluntary command, neuromuscular junction pathology, or compensatory drive due to a reduced number of functional motoneurons.
