Ultralinear heterogeneously integrated ring-assisted Mach–Zehnder interferometer modulator on silicon (2016)

A linear modulator is indispensable for radio frequency photonics or analog photonic link applications where high dynamic range is required. There is also great interest to integrate the modulator with other photonic components, to create a photonic integrated circuit for these applications, with particular focus on silicon photonics integration in order to take advantage of complementary metal–oxide–semiconductor compatible foundries for high-volume, low-cost devices. However, all silicon modulators, including the highest performing Mach–Zehnder interferometer (MZI) type, have poor linearity, partially due to the inherent nonlinearity of the MZI transfer characteristic, but mostly due to the nonlinearity of silicon’s electro-optic phase shift response. In this work, we demonstrate ultralinear ring-assisted MZI (RAMZI) modulators, incorporating heterogeneously integrated III–V multiple quantum wells on silicon phase modulation sections to eliminate the nonlinear silicon phase modulation response. The heterogeneously integrated III–V/Si RAMZI modulators achieve record-high spurious free dynamic range (SFDR) for silicon-based modulators, as high as 117.5  dB·Hz2/3 at 10 GHz for a weakly coupled ring design, and 117  dB·Hz2/3 for a strongly coupled ring design with higher output power. This is a higher SFDR than typically obtained with commercial lithium niobate modulators. This approach advances integrated modulator designs on silicon for applications in compact and high-performance analog optical systems.

Reconfigurable Antennas Based on Electrically Tunable Impedance Surfaces (2001)

We describe an electrically tunable impedance surface, and antennas based on such a surface. The structure is built as a periodic array of electrically small, coupled resonators, commonly known as a high-impedance surface. By tuning the resonance frequency of the surface as a function of position, one can generate an arbitrary refection phase that varies across the surface. This can be used to steer a reflected radio frequency beam, or to tune antennas that are placed near the surface. We describe such a surface that is electrically tunable using commercially available varactor diodes, and offer techniques for achieving full two-dimensional beam steering with a design that is optimized for bandwidth.
Digital thermal monitoring of vascular function: a novel tool to improve cardiovascular risk assessment (2009)

Digital thermal monitoring (DTM) of vascular function during cuff-occlusive reactive hyperemia relies on the premise that changes in fingertip temperature during and after an ischemic stimulus reflect changes in blood flow. To determine its utility in individuals with and without known coronary heart disease (CHD), 133 consecutive individuals (age 54 +/- 10 years, 50% male, 19 with known CHD) underwent DTM during and after 2 minutes of supra-systolic arm cuff inflation. Fingertip temperatures of the occluded and non-occluded fingertips were measured simultaneously. Post-cuff deflation temperature rebound (TR) was lower in the CHD patients and in those with an increased Framingham risk score (FRS) compared to the normal group. After adjustment for age, sex, and cardiac risk factors, TR was significantly lower in those with CHD compared to those without CHD (p < 0.05). This study demonstrates that vascular dysfunction measured by DTM is associated with CHD and an increased FRS, and could potentially be used to identify high-risk patients.

An Integrating Ultraviolet-B Dosemeter Using Phototransferred Thermoluminescence in alpha-Al2O3:C (1997)

Until recently, atmospheric ozone has reflected all but approximately 1% of wavelengths below 320 nm. Recent evidence of ozone depletion in the stratosphere has generated interest in the biological impact on plants and animals resulting from increased exposure to these wavelengths. This has created a need for ultraviolet dosimetry of wavelengths shorter than 320 nm, particularly at southern latitudes. This paper describes the design of a dosemeter which measures absorbed ultraviolet dose, for the wavelength band centred at 307 nm, based upon the phototransferred thermoluminescence properties of alpha-Al&lt;inf&gt;2&lt;/inf&gt;O&lt;inf&gt;3&lt;/inf&gt;:C. Thin-layer alpha-Al&lt;inf&gt;2&lt;/inf&gt;O&lt;inf&gt;3&lt;/inf&gt;:C detectors were used. The calibrated response of the detectors has an average standard deviation of 2.7%. This dosemeter can be used in air or in water. The dosemeter has a near-linear ultraviolet dose response with a dynamic range of at least 3 decades (from an energy fluence of 102 �J.cm-2 to 105 �J.cm-2) and very little temperature dependence in the region of biological interest (273-323 K). The inherent angular dependence of the interference filter used in the dosemeter is partially flattened due to the wavelength dependence of the phototransferred thermoluminescence efficiency in this wavelength region, the shift in the transmission wavelength of the filter as a function of incident angle and through the use of diffusers.
Comportement Dynamique de l’Hélicoptère : contribution à la Définition de l’Architecture Générale (2005)

Le comportement dynamique de l’helicoptere est une preoccupation majeure car il conditionne sa fiabilite, son confort et ses performances. Les problemes de vibrations qui apparaissent dans les phases de mise au point trouvent souvent leur origine dans le design general de l’appareil et il peut etre extremement difficile de revenir sur les choix techniques fondamentaux. Jusqu’a maintenant, la plupart des etudes d’architecture generale ont ete consacrees aux aspects de performances et de couts de production. Ce travail a permis de developper un modele global du comportement dynamique de l’helicoptere, qui apporte des elements complementaires importants pour definir une architecture optimale en matiere de dynamique. Le modele est structure autour des principaux composants de l’helicoptere - le fuselage, le rotor, la chaine de puissance, les systemes antivibratoires et les trains d’atterrissage – modelises analytiquement ou par Elements Finis. L’application des methodes de condensation dynamique a limite considerablement la dimension du modele, permettant notamment des balayages parametriques. La flexibilite du modele permet de nombreuses applications a la fois dans les phases de developpement et dans les phases d’avant-projet. Le modele a ete successivement valide a partir de donnees experimentales puis a ete utilise pour fournir des criteres d’architecture pour minimiser les vibrations du fuselage et augmenter les marges de stabilite de l’appareil au sol.

Detection of the Hardcoded Login Information from Socket and String Compare Symbols (2021)

Internet of Things (IoT) for smart homes enhances convenience; however, it also introduces the risk of the leakage of private data. TOP10 IoT of OWASP 2018 shows that the first vulnerability is ”Weak, easy to predict, or embedded passwords.” This problem poses a risk because a user can not fix, change, or detect a password if it is embedded in firmware because only the developer of the firmware can control an update. In this study, we propose a lightweight method to detect the hardcoded username and password in IoT devices using a static analysis called Socket Search and String Search to protect from first vulnerability from 2018 OWASP TOP 10 for the IoT device. The hardcoded login information can be obtained by comparing the user input with strcmp or strncmp. Previous studies analyzed the symbols of strcmp or strncmp to detect the hardcoded login information. However, those studies required a lot of time because of the usage of complicated algorithms such as symbolic execution. To develop a lightweight algorithm, we focus on a network function, such as the socket symbol in firmware, because the IoT device is compromised when it is invaded by someone via the Internet. We propose two methods to detect the hardcoded login information: string search and socket search. In string search, the algorithm finds a function that uses the strcmp or strncmp symbol. In socket search, the algorithm finds a function that is referenced by the socket symbol. In this experiment, we measured the ability of our proposed method by searching six firmware in the real world that has a backdoor. We ran three methods: string search, socket search, and whole search to compare the two methods. As a result, all methods found login information from five of six firmware and one unexpected password. Our method reduces the analysis time. The whole search generally takes 38 mins to complete, but our methods finish the search in 4-6 min.
Absolute luminosity measurements with the LHCb detector at the LHC (2012)

Absolute luminosity measurements are of general interest for colliding-beam experiments at storage rings. These measurements are necessary to determine the absolute cross-sections of reaction processes ; are valuable to quantify the performance of the accelerator. Using data taken in 2010, LHCb has applied two methods to determine the absolute scale of its luminosity measurements for proton-proton collisions at the LHC with a centre-of-mass energy of 7 TeV. In addition to the classic ''van der Meer scan'' method a novel technique has been developed which makes use of direct imaging of the individual beams using beam-gas ; beam-beam interactions. This beam imaging method is made possible by the high resolution of the LHCb vertex detector ; the close proximity of the detector to the beams, ; allows beam parameters such as positions, angles ; widths to be determined. The results of the two methods have comparable precision ; are in good agreement. Combining the two methods, an overal precision of 3.5% in the absolute luminosity determination is reached. The techniques used to transport the absolute luminosity calibration to the full 2010 data-taking period are presented. © 2012 CERN.
Low Residual Stress in Si Substrate of Annular-Trench-Isolated TSV (2016)

Driven by the need of reduced energy consumption in devices, 3D integration technology by through silicon via (TSV) attracts increasing interests. However, high thermal stress is induced by the large mismatch of the coefficient of thermal expansion (CTE) among the different materials in TSV. The thermal stress is a serious reliability concern for TSV in 3D integration system. In order to solve the stress issues in 3D packaging technology with TSV, we proposed a structure as annular-trench-isolated (ATI) TSV with an extra Si ring between Cu core and SiO2 layer. In this paper, we presented the fabrication process of ATI TSV with two separate etching processes for the parylene-HT trench and solder core while remaining a Si ring between parylene-HT layer and solder core. Note that the trench is narrow with thickness of 2 μm, and its aspect ratio (AR) is high as 7. We successfully deposited the insulator of parylene-HT material in the whole annular trench between Si substrate and Si ring. And the uniformity of deposited parylene-HT layer was observed clearly by 3D X-ray computed tomography method as CT scan. Considering the high aspect ratio of our TSV, difficulty was expected during the conventional process, such as barrier deposition and Cu electroplating. Therefore, solder injection was implemented for depositing the material into the vias of ATI TSV. In order to understand the stress level after fabrication process, the residual stress was investigated with validated simulation model. A lower residual stress in Si substrate was observed in ATI TSV than that of regular TSV due to less solder volume and the redistribution of stress by Si ring in ATI TSV. During thermal cycling, the stress level increased with temperature decreasing from 125°C to -40°C for both ATI and regular TSV. The residual stress measurement of ATI TSV will be performed in further work.

An optimal parallel algorithm for volume ray casting (2002)

Volume rendering by ray casting is a computationally expensive problem. For interactive volume visualization, rendering has to be done in real time (3D frames/sec). Since the typical 3D dataset size is at least 128/sup 3/, the use of parallel processing is imperative. We present an O(log n) EREW algorithm for volume rendering using O(n/sup 3/) processors which can be optimized to O(log/sup 3/ n) time using O(n/sup 3//log/sup 3/ n) processors. We have implemented our algorithm on MasPar MPl200. The implementation results show that a frame from 123/sup 3/ data size is generated in about 3 seconds using 4096 processors.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">&gt;</ETX>
Study of Specific Binding of Maltose Binding Protein to Pyrrole-Derived Bipyridinium Film by Quartz Crystal Microbalance (2002)

The affinity of the maltose binding protein−nitro reductase fusion (MBP−NR) to electropolymerized films of N-(3-pyrrol-1-ylpropyl)-4,4‘-bipyridinium (PPB) has been studied in aqueous medium by the quartz crystal microbalance (QCM) technique. It was found that the MBP domain of MBP−NR exhibits specific binding toward PPB films through the maltose binding site and that the immobilized MBP−NR retains its enzymatic activity toward trinitrotoluene (TNT) reduction. Although some MBP−NR was nonspecifically adsorbed onto a maltose-covered PPB film as well as to a bare Au electrode, in both cases the adsorbed enzyme exhibited no catalytic activity. Nitro reductase (NR) also appeared to adsorb onto the PPB films but did not exhibit any enzymatic activity. The electropolymerization of N-(3-pyrrol-1-ylpropyl)-4,4‘-bipyridinium (PPB) onto a Au electrode in acetonitrile solution was studied by electrochemical quartz crystal microbalance (EQCM). It was found that the extent of polymerization upon pyrrole-centered oxidation decreased with continuous potential scanning. The bipyridinium-localized (quaternized nitrogen) redox reaction appeared to be of the anion-exchange type.
A novel technique fast optimizing the layout parameters of planar spiral inductor (2003)

Based on the physical model of planar spiral inductor and the closed-form inductance expression proposed by Jenei etc., this paper develops a novel technique fast optimizing the layout parameters of spiral inductor. It has been shown Jenei's formula is more accurate than the closed-form formulas presented before, and this paper further demonstrates that Jenei's formula can yield a speed about two magnitude order faster than GreenHouse method with a comparable accuracy. Mathematical analysis of Jenei's formula immediately leads to the derivation of BSA to search out all layout parameters satisfying constraints quickly, then the set with the highest Q can be identified. Experiments show that BSA's searching speed is about three magnitude order faster than the incremental searching algorithm based on GreenHouse method, while the accuracy of both algorithms are similar. The efficiency and accuracy of the optimizing technique are demonstrated by experiments.

A phosphorescent microneedle array for measurement of oxygen partial pressure in tissue (Conference Presentation) (2023)

An oxygen-sensing microneedle array (MNA) was developed to monitor oxygen partial pressure in tissue in a minimally invasive fashion. The working principle is based on the quenching of emission intensity and phosphorescence lifetime of a Pt-core porphyrin embedded into the MNA. It was shown that the MNA is sufficiently robust to puncture human skin and to detect changes in oxygenation within the physiologically relevant range of 0-160 mmHg. Moreover, it was demonstrated that the MNA can be implemented into a wearable wireless optical readout system rendering the MNA a novel and user-friendly technique to monitor oxygen partial pressure in tissue.
Compiler Techniques to Reduce the Synchronization Overhead of GPU Redundant Multithreading (2017)

Redundant Multi-Threading (RMT) provides a potentially low cost mechanism to increase GPU reliability by replicating computation at the thread level. Prior work has shown that RMT's high performance overhead stems not only from executing redundant threads, but also from the synchronization overhead between the original and redundant threads. The overhead of inter-thread synchronization can be especially significant if the synchronization is implemented using global memory. This work presents novel compiler techniques using fingerprinting and cross-lane operations to reduce synchronization overhead for RMT on GPUs. Fingerprinting combines multiple synchronization events into one event by hashing, and cross-lane operations enable thread-level synchronization via register-level communication. This work shows that fingerprinting yields a 73.5% reduction in GPU RMT overhead while cross-lane operations reduce the overhead by 43% when compared to the state-of-the-art GPU RMT solutions on real hardware.
Surface core-level shifts of strontium observed in photoemission of barium strontium titanate thin films (2006)

Angle resolved x-ray photoelectron spectroscopy was used to investigate the surface electronic structure of barium strontium titanate (BST) films. In contrast to previous photoemission studies which identified two chemical states associated with only Ba in the near surface region, the authors have resolved core-level features from surface Sr atoms which provide new insight into the surface electronic structure of BST thin films. The surface Sr 3d features are found to lie approximately 1eV higher in binding energy than the bulk derived peaks. The effects of aqueous and annealing surface treatments and the origin of the Sr surface core-level shifts are discussed.
An analysis of learned proximity functions (2010)

A lot of recent work has shown that the proximity of terms can be exploited to improve the performance of information retrieval systems. We review a recent approach that uses an intuitive framework to incorporate proximity functions into vector based information retrieval systems.More importantly, we present several proximity functions that were learned within this framework and show that they adhere to previously developed constraints regarding the shape of a good proximity function. Finally, we include results of all of the learned functions on unseen test data that shows the consistency of the learning approach used.
Quantification and Monitoring of the Effect of Botulinum Toxin A on Paretic Calf Muscles of Children With Cerebral Palsy With MRI: A Preliminary Study (2021)

<b>Background:</b> Muscles from patients with cerebral palsy (CP) are often spastic and form contractures that limit the range of motion. Injections of botulinum toxin A (BTX) into the calf muscles are an important treatment for functional equinus; however, improvement in gait function is not always achieved. BTX is also used to test muscle weakening for risk evaluation of muscle lengthening surgery. Our aim was to assess the effect of BTX over time on calf muscle properties in pediatric CP patients with MRI. <b>Material and Methods:</b> Six toe-walking CP patients (mean age 11.6 years) with indication for lengthening surgery were prospectively enrolled and received BTX injections into the gastrocnemius and soleus muscles. MRI scans at 3T of the lower legs and clinical examinations were performed pre-BTX, 6 weeks (6w), and 12 weeks (12w) post-BTX. A fat-suppressed 2D multi-spin-echo sequence was used to acquire T<sub>2</sub> maps and for segmentation. Fat fraction maps were calculated from 3D multi-echo Dixon images. Diffusion tensor imaging (DTI) with a 2D echo-planar imaging (EPI) sequence yielded maps of the mean apparent diffusion coefficient (ADC) and of the fractional anisotropy (FA). Hyperintense regions of interest (ROIs) on the T<sub>2</sub>-weighted (T<sub>2</sub>w) images at 6w were segmented in treated muscles. Mean values of T<sub>2</sub>, fat fraction, ADC, and FA were calculated in hyperintense ROIs and in reference ROIs in non-treated muscles. <b>Results:</b> Hyperintensity on T<sub>2</sub>w scans and increased T<sub>2</sub> (group mean ± standard deviation: 35 ± 1 ms pre-BTX, 45 ± 2 ms at 6w, and 44 ± 2 ms at 12w) were observed in all patients at the injection sites. The T<sub>2</sub> increase was spatially limited to parts of the injected muscles. FA increased (0.30 ± 0.03 pre-BTX, 0.34 ± 0.02 at 6w, and 0.36 ± 0.03 at 12w) while ADC did not change in hyperintense ROIs, indicating a BTX-induced increase in extracellular space and a simultaneous decrease of muscle fiber diameter. Fat fraction showed a trend for increase at 12w. Mean values in reference ROIs remained unchanged. <b>Conclusion:</b> MRI showed limited spatial distribution of the BTX-induced effects in pediatric CP patients. It could be a promising non-invasive tool for future studies to test BTX treatment protocols.
