Turbulent Phase Screen for the Study of Imaging System Performance (1995)

Abstract We introduce a nonlinear optical technique for the creation of small-scale phase distortions in coherent optical systems. This technique uses the nonlinear response of a liquid-crystal light valve placed in a two-dimensional optical feedback system to produce a controllable spatially and temporally varying chaotic intensity distribution. The intensity pattern is converted into a spatially varying thin phase screen using a second liquid-crystal light valve. A chaotic phase distortion is then introduced into the output image of a coherent imaging system by propagation through the phase screen.

managed by a Mobile Access Gateway and is always topologically
anchored to the Mobile Access Gateway within the Proxy Mobile IPv6
domain.
A GES mass flow observer for compression systems: design and experiments (2004)

We present a novel globally exponentially stable (GES) mass flow observer for compression systems. A nonlinear separation principle for a class of controllers for the compression system is shown, allowing a control law and the proposed observer to be tuned separately. The results are supported by simulations and experiments.
Scalable power-efficient broadcast over densely deployed wireless ad hoc networks (2005)

Wireless ad hoc or sensor networks usually operate over strictly or partially battery energy limited environments. To prolong the network operating time, energy-efficiency should be carefully considered at every layer of the network protocols and algorithms. Moreover, cross-layer effects and interactions have to be carefully analyzed and utilized. We consider the problem of constructing scalable power-efficient broadcast routing trees over densely deployed wireless ad hoc or sensor networks. The keys to resolving scalability issues are: (1) using a distributed implementation; (2) using a hierarchical approach; (3) using a (partially) shared routing tree structure. We achieve these by using, as a basic building block, the idea of a center-oriented broadcast (COBRA) scheme we presented earlier (Kang, I. and Poovendran, R., IEEE Wireless Commun. and Networking Conf., 2004).
Prevalence and long-term prognosis of patients with ‘narrower than normal’ QRS complexes (2017)

QRS duration <80-85 ms can be observed in a significant proportion of middle-aged healthy males and in similar patients with ischemic heart disease. Narrow QRS were not linked to prognosis in any group.
Obstacle avoidance using predictive vision based on a dynamic 3D world model (2006)

We have designed and implemented a fast predictive vision system for a mobile robot based on the principles of active vision. This vision system is part of a larger project to design a comprehensive cognitive architecture for mobile robotics. The vision system represents the robot's environment with a dynamic 3D world model based on a 3D gaming platform (Ogre3D). This world model contains a virtual copy of the robot and its environment, and outputs graphics showing what the virtual robot "sees" in the virtual world; this is what the real robot expects to see in the real world. The vision system compares this output in real time with the visual data. Any large discrepancies are flagged and sent to the robot's cognitive system, which constructs a plan for focusing on the discrepancies and resolving them, e.g. by updating the position of an object or by recognizing a new object. An object is recognized only once; thereafter its observed data are monitored for consistency with the predictions, greatly reducing the cost of scene understanding. We describe the implementation of this vision system and how the robot uses it to locate and avoid obstacles.

Engineered cementitious composites (ECC) with a high volume of volcanic ash: Rheological, mechanical, and micro performance (2023)

Environmental and economic concerns impel construction materials to employ as many local supplementary cementitious materials as feasible. In this research, a durable Engineered Cementitious Composites (ECC) is developed with the total substitution of fly ash (FA) by volcanic ash (VA). The rheological, mechanical, and micro performance of VA ECC reinforced with polyethylene fibers were comprehensively investigated. Specifically, the severe segregation of VA paste was overcome by systematic engineering of the paste rheology. A minimum paste viscosity of 6 Pa s was found to be effective for fiber dispersion. The compromised compressive strength of VA ECC due to the larger particle size and less pozzolanic activity (compared to FA) was successfully counteracted by the addition of silica fume and the reduction of water to binder ratio. The strain-hardening VA ECC attained 6.7–12.5% of tensile ductility with 46–91 μm of crack width. Moreover, robust self-healing capacity with crack sealing and strength enhancement was demonstrated. The durable ECC holds promise for new constructions and repair of aging infrastructures.

Porosity and density measurements from Rutherford backscattering analysis (RBS) (1985)

Carbon contamination levels in the 5–15-at. % range have been observed in optical thin films deposited on graphite substrates for RBS analysis. The lack of large amounts of carbon in films grown on beryllium indicates that substrate carbon migrates along columnar boundaries and rests in the voids of films evaporated onto graphite. We originally believed that this excess carbon nullified the RBS results but have found that the stoichiometry and density of films deposited on both C and Be substrates were essentially the same. The depth profile of the carbon contamination then serves as a probe of relative film porosity without interfering with the other elemental determinations.
High-fidelity and high-speed modeling and simulation for power conversion systems (2010)

High fidelity and high-speed modeling and simulation are essential analytical tools for the design of sophisticated large-scale power conversion systems, like Oil and Gas compressor drives, Wind and Solar converters, and MRI gradient drivers. This paper presents various approaches to the dynamic modeling of power electronics components, new topologies and their control applicable to their system design and analysis. Discussions on the practical technical issues in the system modeling and simulation will also be presented, with a few demonstrative examples of the power converters in as used in power generation and in compressor drives for Oil and Gas.
Combined search for anomalous pseudoscalar HVV couplings in VH(H→bb‾) production and H → VV decay (2016)

A search for anomalous pseudoscalar couplings of the Higgs boson H to electroweak vector bosons V ( =W or Z) in a sample of proton–proton collision events corresponding to an integrated luminosity of 18.9 fb −1 at a center-of-mass energy of 8 TeV is presented. Events consistent with the topology of associated VH production, where the Higgs boson decays to a pair of bottom quarks and the vector boson decays leptonically, are analyzed. The consistency of data with a potential pseudoscalar contribution to the HVV interaction, expressed by the effective pseudoscalar cross section fractions fa3 , is assessed by means of profile likelihood scans. Results are given for the VH channels alone and for a combined analysis of the VH and previously published H→VV channels. Under certain assumptions, fa3ZZ&gt;0.0034 is excluded at 95% confidence level in the combination. Scenarios in which these assumptions are relaxed are also considered.

Privacy vs. Reward in Indoor Location-Based Services (2016)

Abstract With the advance of indoor localization technology, indoor location-based services (ILBS) are gaining popularity. They, however, accompany privacy concerns. ILBS providers track the users’ mobility to learn more about their behavior, and then provide them with improved and personalized services. Our survey of 200 individuals highlighted their concerns about this tracking for potential leakage of their personal/private traits, but also showed their willingness to accept reduced tracking for improved service. In this paper, we propose PR-LBS (Privacy vs. Reward for Location-Based Service), a system that addresses these seemingly conflicting requirements by balancing the users’ privacy concerns and the benefits of sharing location information in indoor location tracking environments. PR-LBS relies on a novel location-privacy criterion to quantify the privacy risks pertaining to sharing indoor location information. It also employs a repeated play model to ensure that the received service is proportionate to the privacy risk. We implement and evaluate PR-LBS extensively with various real-world user mobility traces. Results show that PR-LBS has low overhead, protects the users’ privacy, and makes a good tradeoff between the quality of service for the users and the utility of shared location data for service providers.
Ultra-Fast Error Correction and Detection for Low-Latency Storage Applications with Emerging Memories (2018)

Emerging memory technologies (like PCM, MRAM and 3D XPoint) can make data storage as fast as the rest of the system. But to cope with the reliability targets of storage applications, error correcting codes (ECCs) able to correct many errors might be needed anyway. Hierarchical codes, ECCs enabling two levels of correction, can be good candidates to satisfy these reliability targets, without impacting (on average) the low-latency characteristics of these technologies. In particular, an Ultra-Fast (UF) ECC can be used as first trial as long as it is able to flag its failures with high probability and low latency. In this paper we design an UF-ECC able to produce a check for incorrect decoding with probability lower than the typical target uncorrectable bit-error rate (UBER) of storage applications (e.g. 1e-15) and with a latency comparable with the UF-ECC correction process.
Generic play-break event detection for summarization and hierarchical sports video analysis (2003)

This paper proposes a single generic real-time (or near real-time) play-break event detection algorithm for multiple sports, which include football, tennis, basketball, and soccer. The proposed algorithm only uses shot-based generic cinematic features, such as shot type and shot length. Detected play-break events are employed for two purposes: 1) all plays in certain sports, such as football and tennis, are presented as summaries, and 2) play-break events, as part of a hierarchical event detection scheme, determine the segments-of-interest for the other event detection algorithms. An example of such event detection algorithms is given for soccer goal events, where the proposed soccer goal detection algorithm exploits the common cinematic techniques that are employed during the breaks that follow the goal plays. We demonstrate the genericity of the proposed play-break detection algorithm over football, tennis, basketball video and the effectiveness of the proposed soccer goal detection algorithm over a large data set.
A social analytics platform for smarter commerce solutions (2014)

When providing customers with a personalized shopping experience, there is tremendous value in understanding and applying social data shared by those consumers. Understanding this data and how best to generate business value from it is the core challenge of many businesses today. Friends, family, and experts alike influence consumers in their shopping preferences and purchase decisions. Yet, the ability of a business to analyze data on such influence, and recommend products and services that best respond to its customers' needs or aspirations, is typically limited by fragmented capabilities; a business relies heavily on the use of spreadsheets, manual market analysis, isolated software, or reactive messaging. This paper offers a solution to this fragmentary approach by introducing a social analytics platform for smarter commerce. This platform provides a holistic understanding of the customer by making use of social and enterprise data to present recommendations and related opinions, and to isolate influencers so as to ultimately provide customers with a personalized shopping experience. The functionality described in this paper is in the context of the retail industry but can be applied to other industries. The paper describes the architecture of the social analytics platform and the various analytics components currently implemented as part of the platform.
Electric Field-Induced Molecular Vibration for Noninvasive, High-Efficiency DNA Transfection (2004)

Gene delivery is an essential research tool for elucidating gene structure, regulation, and function in biomedical research and is the technological basis for gene therapy. However, the application of nonviral vectors in mammalian cell transfection and gene therapy is limited in that current methods require large amounts of exogenous DNA and/or exhibit high cytotoxicity and low transfection efficiency in primary cells. Here we describe the development of a novel, noninvasive gene delivery protocol using plasmid DNA vectors, based on the principle of electric field-induced molecular vibration. This method enables foreign DNA molecules to penetrate the plasma membrane and enter the cytoplasm of both primary mesenchymal progenitor cells and established cell lines of various species, at high efficiency and with low cell mortality. This procedure requires no special reagents, allows stable expression of transduced DNA, and does not interfere with the normal cellular differentiation activities of human and chick mesenchymal progenitors.
Performance of the ATLAS RPC detector and Level-1 muon barrel trigger at √(s)=13 TeV (2021)

Abstract The ATLAS experiment at the Large Hadron Collider (LHC) employs a trigger system consisting of a first-level hardware trigger (L1) and a software-based high-level trigger. The L1 muon trigger system selects muon candidates, assigns them to the correct LHC bunch crossing and classifies them into one of six transverse-momentum threshold classes. The L1 muon trigger system uses resistive-plate chambers (RPCs) to generate the muon-induced trigger signals in the central (barrel) region of the ATLAS detector. The ATLAS RPCs are arranged in six concentric layers and operate in a toroidal magnetic field with a bending power of 1.5 to 5.5 Tm. The RPC detector consists of about 3700 gas volumes with a total surface area of more than 4000 m 2 . This paper reports on the performance of the RPC detector and L1 muon barrel trigger using 60.8 fb -1 of proton-proton collision data recorded by the ATLAS experiment in 2018 at a centre-of-mass energy of 13 TeV. Detector and trigger performance are studied using Z boson decays into a muon pair. Measurements of the RPC detector response, efficiency, and time resolution are reported. Measurements of the L1 muon barrel trigger efficiencies and rates are presented, along with measurements of the properties of the selected sample of muon candidates. Measurements of the RPC currents, counting rates and mean avalanche charge are performed using zero-bias collisions. Finally, RPC detector response and efficiency are studied at different high voltage and front-end discriminator threshold settings in order to extrapolate detector response to the higher luminosity expected for the High Luminosity LHC.
30 Mbps wireless data transmission using an equalized 5-MBaud M-QAM testbed (2002)

The ultimate means of quantifying the performance and gains of equalized wireless communications systems is through the development of a flexible prototype system that can be easily reconfigured for the study of different transmission scenarios. Moreover, such a system can be used to validate the assumptions and results of various theoretical, and simulation based studies. In this paper we report on the development of a 5-MBaud, equalized M-QAM prototype wireless testbed system operating at 2.4 GHz and capable of supporting 4-, 16-, 64-, and 256-QAM constellations. The system can realize any DFE structure up to 16-taps with real-time LMS based coefficient adaptation performed every symbol interval. The paper also reports on a preliminary set of experiments that show achievable transmission with bit error rates of better than 10/sup -7/ and data rates as high as 30 Mbps within a laboratory and in large partitioned office area, rates of 20 Mbps were achieved when transmitting through walls.
Results of a phase II trial of a fludarabine with concomitant application of alemtuzumab in a four-weekly schedule (FluCam) in patients with relapsed CLL. 2nd Interim analysis (2004)

6693 Background: This phase-II-trial investigated the safety and efficacy of a combined modality treatment with fludarabine (F) and the monoclonal anti-CD52 antibody Alemtuzumab (A) in patients (pts) with relapsed CLL. Objectives of this study were to evaluate the feasibility and overall response rate, to assess the response duration and the residual disease after treatment. Methods: The FluCam schedule consists of an escalation phase of Alemtuzumab up to 30 mg within 3 days and followed by the FluCam combination therapy. F was administered at a dosage of 30 mg/m2/d (day 1–3) immediately followed by the 2h antibody-infusion (30mg; d1–3) and repeated on day 29 for up to 6 cycles. Residual disease was monitored by 4-colour flow cytometry. Results: A total of 28 pts have been recruited so far. Baseline characteristics of these pts are: median age 60.7 years (range 38–80 years); male gender: 23; Binet stage C: 21; median number of prior regimens 2 (range 1–8) including fludarabine in 18 pts, Rituximab in 12 pts and Alemtuzumab in 4 pts. In 28/28 pts Overal Response Rate was 86%. The response rate for the first 14 pts was 7 CR, 5 PR, 1 SD, 1 PD. Assessment of minimal residual disease showed negativity in 8/14 pts in peripheral blood and was confirmed in bone marrow in 4/8 pts. FFTF is 16.5 months with 2 pts in ongoing remission. Therapy was well tolerated with WHO grade 3/4 neutropenia in 10/50 evaluable cycles and severe thrombocytopenia in 11/50 cycles. Conclusion: The second interim analysis of this phase-II study of the FluCam protocol in pts with relapsed CLL suggests that this combination is very effective, feasible and safe. The interim analysis of all 28 pts will be presented. A prospective randomised phase-III-study comparing FluCam with fludarabine is underway.
