Reduction of slab boundary artifact with multiple overlapping thin slab acquisition in MR angiography of the cervical carotid artery (1994)

Multiple overlapping thin slab acquisition (MOTSA) is a magnetic resonance (MR) angiography technique combining advantages of two- and three-dimensional time-of-flight techniques. The authors studied three image acquisition parameters (flip angle, TR, and the slab excitation fraction [SEF]) and a postprocessing algorithm, to evaluate their effect on MOTSA image quality, including contrast-to-noise ratio (C/N) and the severity of the slab boundary artifact. By increasing SEF from 0.75 to 1.10, the slab boundary artifact was reduced by 29%-56% (P < .0001). The boundary artifact can be reduced an additional 46% by postprocessing of the overlapping section data. In the healthy volunteers studied, C/N of the cervical carotid artery could be increased sixfold (P < .0001) by increasing the flip angle from 10 degrees to 50 degrees, without significant worsening of the boundary artifact due to top-of-slab saturation. The effect of TR on image quality was not statistically significant for the range studied (52-70 msec). We conclude that the slab boundary artifact seen with the MOTSA MR angiography technique can be reduced significantly by optimizing imaging acquisition parameters and using a postprocessing algorithm to combine overlapping section information.

The superprism effect in a metal-clad terahertz photonic crystal slab (2007)

We demonstrate the superprism effect in a photonic crystal slab at terahertz frequencies. The observed angular dispersion cannot be explained unless the finite slab thickness and its metal cladding boundary conditions are taken into account.
Concurrent Dual Band Six-port based Receivers: Topologies and Calibration Technique (2019)

In this paper, two concurrent dual band architectures for six-port based receiver (SPR) are compared in terms of complexity, performance and hardware implementations. Experimental set-up of each architecture and the recovering of the two envelop signals using augmented Hammerstein model based calibration approach have been performed to illustrate the difference between the two topologies. In order to evaluate the performance of each architecture a comparative study in term of Error Vector Magnitude (EVM), spectrums and constellations has been performed.
A MINIATURIZED CMOS MICROELECTRODE ARRAY SYSTEM FOR SINGLE DROPLET ELEC- TROCHEMISTRY APPLICATIONS (2008)

This paper presents an individually addressabl e 32x32 microelectrode array (MEA) system with built-in CMOS potentiostat for analyzing single droplets and ultra-small volume samples. The proposed system has advantages of smaller sample requirement, higher density, small form factor, low power and higher sensitivity and advanced functionality over the conventional electrode array. Each electrode is a square of side 7um with a center-to-center distance of 37um. The MEA integrated with potentiostat is robustly realized by employing electroless/electrochemical Au plating of native metal layers of CMOS process through a series of simple, maskless, clean-room free die-level post processing.
Intégration à trois dimensions séquentielle: Etude, fabrication et caractérisation (2009)

Currently, 3D integration appears as a way to keep increasing density of integrated circuits, wich has been the driving force of microelectronic industry for now 40 years. This thesis deal with 3D sequential integration where the different levels of transistors are fabricated one after the other on the same substrate. The major challenge is then the fabrication of top layers at low temperature in order to preserve the bottom level from any degradation. In this work, we demonstrate functional 3D cells (inverter, SRAM) in between two stacked layers. Remarkable points are the development of stable bottom FET with salicided acces, fabrication of top active layer by wafer bonding and fabrication of top FET with overall thermal budget limited to 650°C. A part of this thesis is devoted to the identification of potential applications. In the specific case of logic applications, we jointly analyse gain perspectives in term of density, performance and cost. Other applications such as SRAMs and FLASH memories and highly miniaturized imagers appear as potential applications. Furthermore, demonstration of the interest of coupling between stacked transistors is done by the design of improved stability SRAMs.

Infection Rate and Outcomes of Watchman Devices: Results from a Single Center 14-Year Experience (2020)

Background: Left atrial appendage occlusion with the Watchman device is an alternative strategy for stroke risk reduction in patients with non-valvular atrial fibrillation. There are rare case reports of Watchman associated infection. Currently, there is no formal study that evaluated the incidence and outcomes of Watchman-related infections. Methods: All patients who underwent Watchman implantation over a 14 year study period (July 2004 through December 2018) comprised our cohort. Baseline characteristics, procedural data, and post-implantation events were identified. Primary study outcomes included Watchman related infection, other cardiovascular device related infection, bacteremia, and mortality. Results: A total of 181 patients with an average age of 75, and a median CHA2DS2-VASc Score of 4 (interquartile range 2) and a median HAS-BLED Score of 3 (interquartile range 1), were included for analysis. A total of 534.7 patient years of follow up was accrued with an average of 2.9 years per patient. The most common indications for implantation included gastrointestinal bleeding (56 patients; 30.9%) and intracerebral bleeding (51 patients; 28.2%). During follow up, 38 patients (21%) died. Six developed evidence of bacteremia. Only one developed an implantable cardioverter defibrillator (ICD) infection that required complete system extraction. None of the cohort developed Watchman-related device infection during the study period. Conclusion: In a single center study spanning a 14 year period, we report no Watchman-related devices infections. This is despite the presence of patients with bacteremia, as well as an ICD infection requiring extraction. These data suggest that Watchman devices are extremely unlikely to become infected.
A cell-level power management IC in BCD-SOI for partial power processing in Concentrating-PV systems (2014)

This work presents a power management IC used to mitigate the effects of mismatch in Concentrating-Photovoltaic (CPV) systems. The IC contains a bi-directional dc-dc converter, an auxiliary boost converter to generate the internal 10 V power supply, as well as protection and monitoring circuits. The main power converter, with a maximum current rating of 1.5 A, is designed to equalize the voltage between neighbouring CPV cells by using the Δ-converter approach. Due to partial power processing, the converter's power rating and efficiency requirements are relaxed, leading to a more cost-effective solution with a high switching frequency of 3.6 MHz. An on-chip, mixed-signal controller regulates the main converter using a digital voltage loop and an analog hysteretic current-mode loop. The IC has several advanced features to reduce the light-load power consumption, including burst-mode operation in both the auxiliary and main-stage converters, as well as an input supply switching scheme for the internal linear voltage regulators.
Double-Phase-Shifter based Hybrid Beamforming for mmWave DFRC in the Presence of Extended Target and Clutters (2021)

In millimeter-wave (mmWave) dual-function radar-communication (DFRC) systems, hybrid beamforming (HBF) is recognized as a promising technique utilizing a limited number of radio frequency chains. In this work, in the presence of extended target and clutters, a HBF design based on the subarray connection architecture is proposed for a multiple-input multiple-output (MIMO) DFRC system. In this HBF, the double-phase-shifter (DPS) structure is embedded to further increase the design flexibility. We derive the communication spectral efficiency (SE) and radar signal-to-interference-plus-noise-ratio (SINR) with respect to the transmit HBF and radar receiver, and formulate the HBF design problem as the SE maximization subjecting to the radar SINR and power constraints. To solve the formulated nonconvex problem, the joinT Hybrid bRamforming and Radar rEceiver OptimizatioN (THEREON) is proposed, in which the radar receiver is optimized via the generalized eigenvalue decomposition, and the transmit HBF is updated with low complexity in a parallel manner using the consensus alternating direction method of multipliers (consensus-ADMM). Furthermore, we extend the proposed method to the multi-user multiple-input single-output (MU-MISO) scenario. Numerical simulations demonstrate the efficacy of the proposed algorithm and show that the solution provides a good trade-off between number of phase shifters and performance gain of the DPS HBF.
A Study of a DISI Engine with a Centrally Located High-pressure Fuel Injector (2004)

&lt;div class="htmlview paragraph"&gt;Vehicle manufacturers developed two mixture formation concepts for the first generation of gasoline direct-injection (GDI) engines. Both the wall-guided concept with reverse tumble air motion or swirl air motion and the air-guided concept with tumble air motion have the fuel injector located at the side of the combustion chamber between the two intake ports. This paper proposes a new GDI concept. It has the fuel injector located at almost the center of the combustion chamber and with the spark plug positioned nearby. An oval bowl is provided in the piston crown. The fuel spray is injected at high fuel pressures of up to 100 MPa. The spray creates strong air motion in the combustion chamber and reaches the piston bowl. The wall of the piston bowl changes the direction of the spray and air motion, producing an upward flow. The spray and air flow rise and reach the spark plug. The fuel injection pressure, the spray shape and the piston bowl geometry are important factors for the performance of stratified combustion with this concept.&lt;/div&gt;
MRI lung lobe segmentation of pediatric cystic fibrosis patients using a neural network trained with publicly accessible CT datasets (2023)

Pulmonary biomarkers quantifications on a lobar level provide improved specificity against whole-lung analyses. However, lobar quantifications of pulmonary MR data are hardly accessible due to the complex work required for the manual segmentations. Supervised neural networks have shown the premise for automatic segmentation, but it is challenging to gather labelled data for the training. To overcome these limitations, in this work, we &amp;ldquo;translate&amp;rdquo; publicly accessible chest CT datasets and lobe segmentations to pseudo-MR data, and we then train a network able to segment consistently lung lobes of acquired MRI data. The cross-modality approach has excellent prospects to automatize MRI analyses.
Skew aberration: a form of polarization aberration (2011)

We define a new class of aberration, skew aberration, which is a component of polarization aberration. Skew aberration is an intrinsic rotation of polarization states due to the geometric transformation of local coordinates, independent of coatings and interface polarization. Skew aberration in a radially symmetric system has the form of a circular retardance tilt plus coma aberration. Skew aberration causes undesired polarization distribution in the exit pupil. We demonstrate statistics on skew aberration of 2383 optical systems described in Code V's U.S. patent library [Code V Version 10.3 (Synopsys, 2011), pp. 22-24]; the mean skew aberration is 0.89° and the standard deviation is 1.37°. The maximum skew aberration found is 17.45° and the minimum is -11.33°. U.S. patent 2,896,506, which has ±7.01° of skew aberration, is analyzed in detail. Skew aberration should be of concern in microlithography optics and other high NA and large field of view optical systems.
A Novel Nanofabrication Technique for the Array of Nanogap Electrodes (2006)

We demonstrated a sidewall spacer nanofabrication technique for nanogap electrodes fabrication. Nanogap between gold and polycrystalline silicon (ploy-Si) electrodes is defined without using any advanced lithographic techniques. The feature size of nanogap electrodes fabricated using this technique is mainly determined by the thickness of sidewall spacer. The proposed technique showed that reproducible nanogap distances from 10 to 100 nm on the 6 in. wafer were easily obtained. Binding of 15 nm gold nanoparticles across the 10 nm electrodes leading to a drastic change of the electrical conductance has also been demonstrated. Under a bias of 3 V, the conductive current increases from 2 pA to 300 nA after binding of 15 nm gold nanoparticles across the 10-nm electrodes. We believed that this technique can be contributed to the development of high-density nanogap electrodes for applications in biomolecules or nanoparticles detection.

A General and Versatile Approach to Thermally Generated N‐Heterocyclic Carbenes (2004)

The synthesis of N-heterocyclic carbene (NHC) adducts by condensation of diamines with appropriately substituted benzaldehydes is described. This simplified approach provides the NHC adduct without first having to generate the carbene followed by its protection. These adducts undergo thermal deprotection to generate N-heterocyclic carbene in situ. Adduct decomposition temperatures were investigated as a function of catalyst structure by using thermal analysis and spectroscopic techniques. Importantly, unlike adducts derived from chloroform, the new pentafluorobenzene-based adducts are more readily prepared and are stable at room temperature. The utility of these adducts as organic catalyst precursors for living ring-opening polymerization (ROP) of lactide, transesterification reactions, and the synthesis of N-heterocyclic carbene ligated organometallic complexes is also described.
A smarter process for sensing the information space (2010)

As a result of the growth of the Internet, the amount of available information is exponentially increasing. However, increasing the amount of information does not imply increasing usefulness. Furthermore, as the complexity of business relationships increases, there is a natural tendency toward less structured interaction between entities. This highlights the growing relevance of unstructured information in documenting the interactions of organizations and individuals. Analyzing and making sense of this unstructured information space requires more than text-mining algorithms; it requires a strategic approach. We propose a unified approach that addresses a variety of information space analytics problems. Our method for making sense of unstructured data is described by six steps that are analogous to the algebraic order of operations PEMDAS (parenthesis, exponent, multiplication, division, addition, and subtraction). These basic text-mining operations can be combined in many interesting ways to handle a diverse set of problems, and just as in algebra, it is critical that these operations be performed in the correct order to guarantee a meaningful result. In this paper, we describe how PEMDAS has been implemented within organizations to enable decisions that produced measurable business value.
Code motion of control structures in high-level languages (1986)

One trend among programmers is the increased use of abstractions. Through encapsulation techniques, abstractions extend the repertory of data structures and their concomitant operations that are processed directly by a compiler. For example, a compiler might not offer sets or set operations in its base language, but abstractions allow a programmer to define sets in terms of constructs already recognized by the compiler. In particular, abstractions can allow new constructs to be defined in terms of other abstractions. Although significant power is gained through the use of layered abstractions, object code quality suffers as increasingly less of a program's data structures and operations are exposed to the optimization phase of a compiler. Multiple references to abstractions are also inefficient, since the interaction between abstractions is often complex yet hidden from a compiler. Abstractions are most flexible when they are cast in general terms; a specific invocation is then tailored by the abstraction to obtain the appropriate code. A sequence of references to such abstractions can be inefficient due to functional redundancy that cannot be detected at compile-time. By integrating the references, the offending segments of code can be moved to a more advantageous position. Although procedure integration materializes abstracted constructs, the abstractions can still be ineligible for optimization using current techniques; in particular, abstractions often involve loops and conditional branches that can obscure code that would otherwise be eligible for code motion.
Predicting the vibroacoustic response of satellite equipment panels (2003)

Modern satellites are constructed of large, lightweight equipment panels that are strongly excited by acoustic pressures during launch. During design, performing vibroacoustic analyses to evaluate and ensure the integrity of the complex electronics mounted on the panels is critical. In this study the attached equipment is explicitly addressed and how its properties affect the panel responses is characterized. FEA and BEA methods are used to derive realistic parameters to input to a SEA hybrid model of a panel with multiple attachments. Specifically, conductance/modal density and radiation efficiency for nonhomogeneous panel structures with and without mass loading are computed. The validity of using the spatially averaged conductance of panels with irregular features for deriving the structure modal density is demonstrated. Maidanik's proposed method of modifying the traditional SEA input power is implemented, illustrating the importance of accounting for system internal couplings when calculating the external input power. The predictions using the SEA hybrid model agree with the measured data trends, and are found to be most sensitive to the assumed dynamic mass ratio (attachments/structure) and the attachment internal loss factor. Additional experimental and analytical investigations are recommended to better characterize dynamic masses, modal densities and loss factors.
[Preservation of ovarian function in 2 young women with Hodgkin disease by laparoscopic transposition of the ovaries prior to abdominal irradiation]. (1999)

Hodgkin's disease was diagnosed in two girls aged 11 and 15 years, in stages IIIB and IIIA, respectively. Because of localizations in the para-aortic and para-iliac lymph nodes, irradiation of these lymph nodes was considered necessary; this would result in loss of the ovarian function. Transposition of the ovaries was performed by laparoscopy; in the first patient both ovaries were fixed behind the uterus to the midline, in the second the right ovary was fixed at the level of the right iliac crest and the left ovary to the pelvic wall in the cranial direction. Subsequently, the planned irradiation was carried out. In the first patient, the menarche started at the age of 13, in the second, the menstrual cycle returned to normal. In girls and young women needing irradiation of the pelvis, ovarian function may be preserved by transposition of the ovaries in a high-lateral direction, to the level of the iliac crest. If the irradiation has to include the region of para-iliac lymph nodes, as in patients with Hodgkin's disease in stage III, fixation of the adnexa in the midline at a low level behind the uterus may also be considered. Both interventions are possible by laparoscopy. The disadvantage of the midline oophoropexy is that relatively much scattered radiation can reach the ovary in spite of shielding of the median area; the advantage is that a natural form of conception remains possible (tubal function is preserved).
Adaptive beamforming arrays for smart antenna systems: a comprehensive performance study (2004)

A performance study of LMS adaptive beamformers has been carried out by investigating the effect of parameters related to both the beamforming array and signal environment. These parameters include number of beamformer array elements and their spacing, as well as the number of users and their angular separation. The performance study is essential for an optimal design of smart antenna systems utilizing LMS beamformers.

Self-Reverse-Blocking Control of Dual-Gate Monolithic Bidirectional GaN Switch With Quasi-Ohmic on-State Characteristic (2022)

Converter topologies such as current-source rectifiers and inverters require switching devices with bipolar voltage blocking and unidirectional current conduction capability. Recently available dual-gate GaN monolithic bidirectional switches (MBDSs) can mimic such self-reverse-blocking (SRB) behavior if the MBDS’ two gates are controlled accordingly, but thus need twice the number of gate signals and gate drive circuits. Therefore, we propose cascode-diode control (i.e., without additional sensing or gate drive circuitry) of one MBDS gate using a cascode configuration with a low-voltage silicon Schottky diode. The resulting SRB-MBDS features quasi-ohmic conduction characteristic and single-gate control. We provide static and dynamic measurements of a discrete proof-of-concept realization (600-V, 190-m <inline-formula xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink"><tex-math notation="LaTeX">$\mathrm{\Omega }$</tex-math></inline-formula> GaN MBDS; 40-V, 10-A silicon Schottky diode) that demonstrate the proposed SRB-MBDS’ feasibility.
