CMOA: Continuous moving object anonymization (2012)

This paper proposes a continuous anonymization method for a trajectory stream. In today's mobile environment, positions of moving objects are frequently sensed and collected. For real-time movement pattern analyses of people and automobiles, trajectory streams have attracted a lot of attention. Trajectory streams lead to sensitive locations, such as homes and personal hospitals. Additionally, a set of spatio-temporal data might identify a user from a trajectory stream. Therefore, publishing original trajectory streams may cause critical breaches of privacy. To protect privacy of users, we need a mechanism which makes it difficult to identify users from crowds of trajectory streams. Several techniques for anonymizing trajectories have been proposed. Anonymized trajectories can be published without concerning about privacy issues. However, for the continuous publishing of trajectory streams, existing trajectory anonymization methods are not suitable because they anonymize the overall trajectories at a time. If the existing methods are applied in the continuous publishing, the resolution of anonymized trajectory is hugely degraded or trace-ability is lost. In this paper, we propose an anonymization technique for a trajectory stream. The method continuously anonymizes trajectory streams one by one, and dynamically reforms anonymized trajectory streams to improve the resolution. The experiments showed that our method could keep the resolution at a constant level.
Distal Femoral Valgus Is Highly Variable in Patients Undergoing Total Knee Arthroplasty (2018)

IntroductionOptimal alignment and position of implants is an important goal In TKA. Conventional mechanical instruments use the anatomic axis and “average” anatomy to position the femoral component to achieve acceptable mechanical limb alignment. Numerous studies have documented the frequency of TKA outliers (+/− 3 degrees) to be 30% or more. The purpose of this study was to determine the “true” distal femoral valgus angle of the femur.Methods13,586 CT scans of patients undergoing TKA with patient specific instruments were analyzed. Three-dimensional reconstructions were performed and the distal femoral anatomic and mechanical axes were measured digitally. The distal femoral valgus angle was defined and the difference between the anatomic and mechanical axes of the distal femur.ResultsThe average distal femoral valgus angle was 5.7 +/− 2.3 degrees. The range was one-degree varus to 16 degrees valgus. 13.8% of patients had greater than 9 or less than 3 degrees of femoral valgus.ConclusionThe anatomy of the...

Quantitating the Occult (1985)

Physicians are faced all too frequently with middle-aged patients who present with vague abdominal problems or rectal bleeding and who on evaluation are found to have colon cancer. A discouraging proportion of these relatively young people already have local spread of the disease or metastases to the liver.Spurred on by such cases, many physicians encourage asymptomatic patients who are over 40 to undergo annual testing for occult blood in stool as part of a screening program, in the hope that colon cancers may be detected at an early, curable stage or that adenomatous polyps may be found and removed . . .

Mode-Hopping Phenomena in the InGaN-Based Core–Shell Nanorod Array Collective Lasing (2018)

A two-dimensional monolithic InGaN-based core–shell nanorod array was excited under a varying temperature. We observed an abrupt dominant mode hopping from 3.29 to 3.41 eV in the collective lasing as the temperature decreased from T = 240 to 225 K. Photoluminescence under a near-threshold pumping density revealed the splitting of spontaneous emission between the core and the shell with a decreasing temperature. The bandgap evolution of GaN and InGaN showed opposite trends due to the interaction of temperature effects and bandgap renormalization effects. Theoretical simulation revealed the differences of gain spectra evolution between room temperature and low temperature due to the difference in the carrier dynamics. In the optically coupled nanorod array, the dominant lasing mode was not only determined by its structure, but also strongly influenced by external operating conditions. Rather than singular microcavity lasers, the coupled nanorod array demonstrated a broader parameter space for on-chip wavelength manipulation.

Active reflectors for high performance lithium niobate on silicon dioxide resonators (2015)

This paper reports on the design and demonstration of active reflectors for enhancing the electromechanical coupling (k <sub xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">t</sub> <sup xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">2</sup> ) and suppressing spurious modes in Laterally Vibrating Resonators (LVRs) based on X-cut ion-sliced Lithium Niobate (LN) thin film on silicon dioxide (SiO <sub xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">2</sub> ). By adding electroded quarter wavelength (λ/4) regions at the two ends of the resonant plate, active reflectors (since an electrical signal is applied to them) are formed to improve the device performance. Optimized active reflectors that resort to 100% metal coverage of the λ/4 extensions enable: (i) a considerable improvement of k <sub xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">t</sub> <sup xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">2</sup> , (ii) spurious mode suppression, and robustness to processing (iii) misalignment and (iv) over/under-etching. 2X improvement in k <sub xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">t</sub> <sup xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">2</sup> and significant suppression of in-band spurious vibrations were attained with respect to the conventional design (without active reflectors) despite 0.5 μm misalignment and more than 0.5 μm overetch in the fabrication process.
Wideband capon beamforming with pre-steering (2016)

Passive beamforming in ultrasound therapy monitoring strives to estimate the energy emanating from a near-field source location by “steering” the wideband sensor signals with time delays, summing the steered signals, and computing the energy over a time interval. An image of the spatial energy distribution is obtained by repeating the process over a grid of imaging locations. Capon beamforming provides adaptive interference reduction through real-valued beamforming weights that are determined from the spatial covariance matrix of pre-steered wideband signals. We analyze the interference rejection of this Capon beamformer with pre-steered wideband signals and explain its effectiveness in ultrasound therapy monitoring.

Photonic crystal slabs demonstrating strong broadband suppression of transmission in the presence of disorders (2004)

We characterize the transmission spectra of out-of-plane, normal-incidence light of two-dimensional silicon photonic crystal slabs and observe excellent agreement between the measured data and finite-difference time-domain simulations over the 1050-1600-nm wavelength range. Crystals that are 340 nm thick and have holes of 330-nm radius on a square lattice of 998-nm pitch show 20-dB extinction in transmission from 1220 to 1255 nm. Increasing the hole radius to 450 nm broadens the extinction band further, and we obtain >85% extinction from 1310 to 1550 nm. Discrepancies between simulation and measurement are ascribed to disorder in the photonic lattice, which is measured through image processing on high-resolution scanning electron micrographs. Analysis of crystal imperfections indicates that they tend to average out narrowband spectral features, while having relatively small effects on broadband features.

Uplink Power Control for an OFDMA Mobile Cellular System (2007)

In this paper, we will investigate the effects of uplink closed-loop power control in a mobile cellular system that employs OFDMA multiple access for the uplink. Analytical results are derived to compare open-loop with closed-loop power control approaches. Furthermore, system-level simulation results modeling multi-users in a multi-cell deployment scenario will also be discussed. The analytical results show the condition under which the open-loop approach for transmit power control may become unstable, leading to increases in transmit power levels with no improvement in the level of signal to interference and noise ratio (SINR) achieved. Simulation results have also indicated that closed-loop power control is more effective in enhancing throughput performance of users at the cell edge. The simulation models the effects of adaptive modulation coding (AMC) by including multiple SINR targets for the closed-loop power control. Closed-loop power control can be effective in supporting user applications that require medium to low data rates, using transmit power levels that are just sufficient for the desired applications, while avoiding the creation of high levels of intercell interference.

Selective anergy of V beta 8+ T cells in human immunodeficiency virus-infected individuals. (1994)

We have analyzed the V beta usage by CD4+ and CD8+ T cells from human immunodeficiency virus (HIV)-infected individuals in response to an in vitro stimulation with the superantigenic erythrogenic toxin A (ETA) of Streptococcus pyogenes. ETA amplifies specifically CD4+ and CD8+ T cells from control donors expressing the V beta 8 and the V beta 12 elements. When peripheral T cells from asymptomatic HIV-infected individuals were stimulated with ETA, there was a complete lack of activation of the V beta 8+ T cell subset, whereas the V beta 12+ T cell subset responded normally to the superantigen. This V beta-specific anergy, which was also observed in response to staphylococcal enterotoxin E (SEE), affected both CD4+ and CD8+ T cells and represented an intrinsic functional defect rather than a specific lack of response to bacterial superantigens since it was also observed after a stimulation with V beta 8 monoclonal antibodies. The V beta 8 anergic T cells did not express interleukin 2 receptors (IL-2Rs) and failed to proliferate in response to exogenous IL-2 or IL-4, suggesting that this anergy was not a reversible process, at least by the use of these cytokines. The unresponsiveness of the V beta 8 T cell subset is frequent since it was found in 56% of the patients studied, and comparison of the clinical status of responder vs. anergic patients indicated that the only known common factor between them was HIV infection. In addition, it is noteworthy that the anergy of the V beta 8 subset may be a very early phenomenon since it was found in a patient at Centers for Disease Control stage I of the disease. These data provide evidence that a dominant superantigen may be involved in the course of HIV infection and that the contribution of HIV has to be considered.

Asymptotic Model of Acoustic Scattering by Thin Elastic Shells in Fluids (2021)

An asymptotic model of acoustic scattering by a thin elastic shell is developed. The shell is replaced with effective boundary conditions involving surface differential operators. The shell thickness is considered a small parameter. Analytical solutions within asymptotic approximations in the spherical case are compared with the exact solution for an elastic spherical layer. Resonance effects of the first and third order in the shell thickness are distinguished.
COVIDLite: A depth-wise separable deep neural network with white balance\n and CLAHE for detection of COVID-19 (2020)

Background and Objective:Currently, the whole world is facing a pandemic\ndisease, novel Coronavirus also known as COVID-19, which spread in more than\n200 countries with around 3.3 million active cases and 4.4 lakh deaths\napproximately. Due to rapid increase in number of cases and limited supply of\ntesting kits, availability of alternative diagnostic method is necessary for\ncontaining the spread of COVID-19 cases at an early stage and reducing the\ndeath count. For making available an alternative diagnostic method, we proposed\na deep neural network based diagnostic method which can be easily integrated\nwith mobile devices for detection of COVID-19 and viral pneumonia using Chest\nX-rays (CXR) images. Methods:In this study, we have proposed a method named\nCOVIDLite, which is a combination of white balance followed by Contrast Limited\nAdaptive Histogram Equalization (CLAHE) and depth-wise separable convolutional\nneural network (DSCNN). In this method, white balance followed by CLAHE is used\nas an image preprocessing step for enhancing the visibility of CXR images and\nDSCNN trained using sparse cross entropy is used for image classification with\nlesser parameters and significantly lighter in size, i.e., 8.4 MB without\nquantization. Results:The proposed COVIDLite method resulted in improved\nperformance in comparison to vanilla DSCNN with no pre-processing. The proposed\nmethod achieved higher accuracy of 99.58% for binary classification, whereas\n96.43% for multiclass classification and out-performed various state-of-the-art\nmethods. Conclusion:Our proposed method, COVIDLite achieved exceptional results\non various performance metrics. With detailed model interpretations, COVIDLite\ncan assist radiologists in detecting COVID-19 patients from CXR images and can\nreduce the diagnosis time significantly.\n
Evolution of Downlink Multi-Antenna Techniques throughout E-UTRAN LTE Releases (2011)

First we walk through the design of MIMO transmission schemes, reference signals and channel state information feedback from Release 8 to the latest Release 10 of the specifications. We provide extensive system simulation results for downlink single- and multi-user MIMO, demonstrating the clear performance benefits of the advanced spatial processing techniques developed throughout the evolution of LTE, and confirming the state-of-the-art design of LTE multi-antenna techniques. Finally, we provide a glimpse to the future multi-antenna topics currently being studied in 3GPP, presenting also simulation results on the most promising candidate feature.
Characterization of linewidth variation on 248- and 193-nm exposure tools (2001)

The line-width variation of a 193 nm lithographic process utilizing a 0.60 NA scanner and a binary reticle is compared to that of a 248 nm lithographic processes utilizing a 0.68 NA scanner and a variety of reticle technologies. These include binary, attenuated PSM with assist features and alternating PSM reticles. Despite the fact that the 193 nm tool has a lower NA and that the data was generated using a binary reticle, the 193 nm lithographic process allows for the line-width values to be pushed lower than previously achieved with 248 nm lithographic processes. The 3-sigma values from 4000 electrical line-width measurements per wafer (160 measurements per 25*25 mm field, 25 fields per wafer) were calculated for different mask features. The 193 nm process was capable of reaching line-widths needed for future generations of advance logic chips. Compared to the 193 nm process utilizing a binary reticle, only the 248 nm processes utilizing either an attenuated PSM with assist features or an alternating PSM reticle had similarly low line-width variation. The 248 nm processes utilizing a binary reticle had higher line-width variation even at larger poly gate conductor line-widths.
A prospective clinical study on the mechanisms underlying critical illness myopathy—A time‐course approach (2022)

Abstract Background Critical illness myopathy (CIM) is a consequence of modern critical care resulting in general muscle wasting and paralyses of all limb and trunk muscles, resulting in prolonged weaning from the ventilator, intensive care unit (ICU) treatment and rehabilitation. CIM is associated with severe morbidity/mortality and significant negative socioeconomic consequences, which has become increasingly evident during the current COVID‐19 pandemic, but underlying mechanisms remain elusive. Methods Ten neuro‐ICU patients exposed to long‐term controlled mechanical ventilation were followed with repeated muscle biopsies, electrophysiology and plasma collection three times per week for up to 12 days. Single muscle fibre contractile recordings were conducted on the first and final biopsy, and a multiomics approach was taken to analyse gene and protein expression in muscle and plasma at all collection time points. Results (i) A progressive preferential myosin loss, the hallmark of CIM, was observed in all neuro‐ICU patients during the observation period (myosin:actin ratio decreased from 2.0 in the first to 0.9 in the final biopsy, P &lt; 0.001). The myosin loss was coupled to a general transcriptional downregulation of myofibrillar proteins ( P &lt; 0.05; absolute fold change &gt;2) and activation of protein degradation pathways (false discovery rate [FDR] &lt;0.1), resulting in significant muscle fibre atrophy and loss in force generation capacity, which declined &gt;65% during the 12 day observation period (muscle fibre cross‐sectional area [CSA] and maximum single muscle fibre force normalized to CSA [specific force] declined 30% [ P &lt; 0.007] and 50% [ P &lt; 0.0001], respectively). (ii) Membrane excitability was not affected as indicated by the maintained compound muscle action potential amplitude upon supramaximal stimulation of upper and lower extremity motor nerves. (iii) Analyses of plasma revealed early activation of inflammatory and proinflammatory pathways (FDR &lt; 0.1), as well as a redistribution of zinc ions from plasma. Conclusions The mechanical ventilation‐induced lung injury with release of cytokines/chemokines and the complete mechanical silencing uniquely observed in immobilized ICU patients affecting skeletal muscle gene/protein expression are forwarded as the dominant factors triggering CIM.
