EMI Suppression Properties of Fe-ferrite Film Prepared by Aerosol Deposition Method (2007)

The Aerosol Deposition Method (ADM) is effective for the preparation of thick films with high deposition rate. We studied EMI (Electromagnetic Interference) suppression properties of Fe-ferrite film prepared by ADM on a polyimide film. The deposition rates of Fe-ferrite composite films increased with in proportion to the Fe ratio of Fe-ferrite powder before deposition. The Fe-ferrite composite film with Fe: ferrite = 8: 2 (weight ratio) showed a remarkable EMI mitigation characteristic for microstrip line structures in the range of 2.5-10 GHz. We also applied Fe-ferrite composite films by ADM on FPC (Flexible Printed Circuit) for practical use. The FPC was connected to a transmitter board and a receiver board. Compared with a FPC without Fe-ferrite composite films, the FPC with one could suppress electric field intensity by about 1 OdB around 1.2 GHz in the far field, which was resonance frequency of the FPC.
Design of a multifunctional SRR-loaded printed monopole antenna (2012)

In this article, we present the design and the operation principles of a printed monopole antenna loaded with two identical split-ring resonators (SRRs). The idea is to use the SRRs not only to miniaturize the antenna dimensions but also to introduce multiple resonances, which can be properly selected by using electronic switches placed across the four gaps of the two SRRs. The physics behind the operation of the proposed antenna as well as the design procedure are presented in details and the expected multifrequency operation is demonstrated and supported by proper full-wave numerical simulations. By properly combining the ON/OFF status of the four switches, in fact, it is possible to either change the operation frequency and/or the shape of the radiation pattern of the printed monopole or even add new operation frequencies. The proposed SRR-loaded printed antenna, thus, may find applications in mobile communications requiring pattern diversity and multiple operation frequencies. © 2012 Wiley Periodicals, Inc.

Design and Evaluation of a Prototype Rear Obstacle Detection and Driver Warning System (2005)

This study, concerned with the development of driver interface criteria for a rear obstacle detection system, assessed the appropriateness of alternative warning timing algorithms and evaluated various interface approaches for presenting warning information to drivers. Interface testing used a minivan and a passenger sedan equipped with a prototype rear obstacle detection system. Two different warning timing algorithms and four different interface conditions were examined. The appropriateness of the warning timing algorithms was tested using an alerted backing procedure wherein drivers backed to known obstacles and braked in response to the warning. A surprise event scenario was also included in order to examine driver reaction to the warning under unexpected conditions. Alerted backing results suggest that although both timing algorithms led to few target strikes, one algorithm led to more acceptable ratings, fewer target strikes and close calls, and less urgent braking. None of the interface warning conditions reliably induced avoidance braking under the surprise event condition. Actual or potential applications of this work include the appropriate design of effective backing warning systems.
Equilibrium reconstruction of the safety factor profile in tokamaks from motional Stark effect data (1994)

The motional Stark effect (MSE) diagnostic has been used to obtain accurate measurements of the internal magnetic pitch angle tan−1(BZ/BT) in finite-pressure tokamaks. The MSE data, together with external magnetic probe data, are used to reconstruct self-consistently the equilibrium safety factor (q) profile and, hence, the plasma current density, in the Tokamak Fusion Test Reactor (TFTR) [Plasma Phys. Controlled Nucl. Fusion Res. 1, 51 (1986)] and the Princeton Beta Experiment-Modified (PBX-M) tokamak [Phys. Fluids B 2, 1271 (1990)]. An efficient computational scheme, based on an inverse coordinate representation of the magnetic field, has been developed to solve the coupled nonlinear equations describing both the magnetohydrodynamic (MHD) equilibrium and the q profile, which best match all the experimental data.
Correlation of spatially resolved photoluminescence and viscoelastic mechanical properties of encapsulating EVA in differently aged PV modules (2016)

Abstract The photoluminescence of ethylene vinyl acetate (EVA) in aged photovoltaic modules shows specific spatial patterns on the scale of the cells in the module that depend on the aging conditions. It is the aim of this work to investigate the correlation of these photoluminescence patterns to the viscoelastic mechanical properties of the encapsulating EVA. For this, the degradation under various conditions of two specimen sets of polycrystalline silicon photovoltaic mini‐modules, comprising EVA as encapsulating polymer, is investigated using spatially resolved, ultraviolet‐excited photoluminescence. Samples of the encapsulation EVA are systematically extracted from the modules for spatially resolved dynamic mechanical characterization. A correlation between the spatial distribution of the photoluminescence intensity and the values of storage modulus and loss factor of the EVA is found. An increase in the values for storage modulus and a decrease of the loss factor of the EVA from the edge of the cell towards the center are observed for all samples. We conclude that diffusion‐limited oxidation must be considered for aging studies of the encapsulation EVA and that photoluminescence detection can reveal the scale on which such diffusion processes occur.

Infrared photodissociation of benzene dimers in the 1000 cm−1 frequency region (1986)

The infrared photodissociation of benzene dimers has been investigated in the frequency region of the CO2 laser. A single absorption peak is observed with a maximum at 1038 cm−1, and a full width at half-maximum of about 2 cm−1. The laser fluence dependence of the dissociation yield and two-laser hole burning experiments both indicate that the linewidth is mostly homogeneous. The benzene monomer fragments from the photodissociation emerge with an isotropic angle distribution. A relatively large fraction of the available energy goes into product translation, and the remainder into rotation.
Electrostatic aluminum micromirrors using double-pass metallization (1997)

The fabrication of aluminum spatial light modulators has so far required costly process engineering efforts. In this paper, a low-cost process approach is presented, suitable for the manufacture of electrostatic micromirror arrays. The mirrors are made from the second metallization of complementary metal oxide semiconductor (CMOS) or bipolar processes deposited in two passes. This metal2 is protected by a photoresist layer that can be patterned using the top passivation mask of the process. No additional layer deposition and layer structuring is necessary during postprocessing. The actuators are released in a simple surface micromachining postprocessing sequence based on a sacrificial aluminum and silicon dioxide etch. Our approach allows one metallization to be used for both the circuitry and the electrooptomechanicaI devices. Deformable mirror arrays of up to 16/spl times/16 pixels were fabricated. Static self-consistent electromechanical simulations using the finite-element method (FEM) toolbox SOLIDIS were performed for a theoretical analysis and optimization of the actuator devices.
Water-soluble bio-sourced resists for DUV lithography in a 200/300 mm pilot line environment (2023)

Water-based bio-sourced resists are promising candidates as alternatives for deep ultraviolet (DUV) lithography by replacing current photoresists issued from petro-chemistry for microelectronics application. Chitosan films produced from seafood industry wastes enable patterning processes free of organic solvent and alkali-based developers, by substitution with water. After demonstrating high-resolution patterning at lab-scale after transfer into silica 10 mm wafer, we investigate here the industrial pre-transfer chitosan-based photoresist on the 300 mm pilot line scale at CEA-Leti for 193 nm DUV lithography.
Influence of Molecular Orientation on Charge-Transfer Processes at Phthalocyanine/Metal Oxide Interfaces and Relationship to Organic Photovoltaic Performance (2015)

The effect of the molecular orientation distribution of the first monolayer of donor molecules at the hole-harvesting contact in an organic photovoltaic (OPV) on device efficiency was investigated. Two zinc phthalocyanine (ZnPc) phosphonic acids (PA) deposited on indium tin oxide (ITO) electrodes are compared: ZnPc(PA)4 contains PA linkers in all four quadrants, and ZnPcPA contains a PA linker in one quadrant. ZnPcPA monolayers exhibited a broad distribution of molecular orientations whereas ZnPc(PA)4 adsorption produced a monolayer with a narrower orientation distribution with the molecular plane more parallel to the ITO surface. We used potential-modulated attenuated total reflectance spectroelectrochemistry (PM-ATR) to characterize the charge-transfer kinetics of these films and show that the highest rate constants correspond to ZnPc subpopulations that are oriented more parallel to the ITO surface plane. For ZnPc(PA)4, rate constants exceeded 104 s–1 and are among the highest ever reported for a surface-confined redox couple, which is attributable to both its orientation and the small ZnPc–electrode separation distance. The performance of OPVs with ITO hole-harvesting contacts modified with ZnPc(PA)4 was comparable to that achieved with highly activated bare ITO contacts, whereas for ZnPcPA-modified contacts, the OPV performance was similar to that observed with (hole-blocking) alkyl-PA modifiers. These results demonstrate the synergism between molecular structure, energetics, and dynamics at interfaces in OPVs.

Reliable light field multiwindow disparity estimation (2016)

In this work we propose a depth estimation method for light field images. Light field images can be considered as a collection of 2D images taken from different viewpoints arranged in a regular grid. This means that disparity is the same for any pair of consecutive views, in both vertical and horizontal directions. We exploit this fact by computing disparity maps between specific pairs of views. This computation is done by a state of the art two-view stereo method which also provides a mask of incorrect matches. Then, disparity maps and masks are used to obtain a unique and robust estimation. Finally, we show the performance of the algorithm by means of different experiments.
Ion Mobility Spectrometry of Macromolecules with Dipole Alignment Switchable by Varying the Gas Pressure (2019)

Since inception in the 1980s, differential or field asymmetric waveform ion mobility spectrometry (FAIMS) was implemented at or near the ambient gas pressure (AP). Recently, we developed FAIMS at 15-30 Torr within a mass spectrometer and demonstrated it for small and medium sized ions, including peptides. The overall separation properties mirrored those at AP, reflecting the shared underlying physics. Here we extend these analyses to macromolecules, namely, multiply charged proteins generated by electrospray ionization. The spectra for smaller proteins (ubiquitin, cytochrome c, myoglobin) again resemble those at AP, producing features for one or a few adjacent well-defined conformers with type C behavior. Large proteins (single aldolase domain and albumin) now follow, with no broad bands for type A or B species that dominated at 1 atm. Those unique behaviors were ascribed to pendular ions with electric dipoles reversibly locked by the strong field in FAIMS. Disappearance of those bands shows loss of alignment predicted by first-principles theory, further supporting dipole locking at AP. The capability to modulate dipole alignment by varying gas pressure at constant normalized field provides the basis for determining the ion dipole moment and direction within the molecular frame from the pressure of onset and characteristics of spectral drift. This new approach to alter FAIMS separations of proteins could make a powerful tool for structural biology and be useful for proteomics and imaging.
Structure and Properties of Soybean Milk Modified Polyacrylonitrile Fiber (2011)

After a series of chemical procedures of surface hydrolysis, acidchloride reaction and grafting, Polyacrylonitrile (PAN) fiber was grafted from soybean milk and the soy protein-modified PAN fiber was obtained. The structures and morphologies of the grafted fiber were characterized by Fourier transform infrared spectroscopy (FTIR), X-Ray diffraction (XRD) and scanning electron microscope (SEM).The results show that the surface of PAN fiber was covered by soy protein overlay film. Moisture absorption and mechanical properties were investigated. The grafted PAN fiber presented better hygroscopicity and still meet the requirement for wearing.
Metal-Induced Reactions of<i>O</i>-Nitroso Aldol Products (2006)

Lewis acid catalysts play an important role in the transformation of α-aminooxy ketones (O-nitroso aldol products). Three different reactions of O-nitroso aldol products promoted by metal ions are described.
An approach to overcoming specific difficulties with cardiac resynchronization therapy in children. (2008)

Cardiac resynchronization therapy (CRT) is now a well established treatment modality for adult patients with drug refractory symptomatic congestive heart failure. Multiple large-scale studies have clearly demonstrated reduction in heart failure-related morbidity with CRT1-4. More recently, a likely independent mortality benefit with CRT has also been shown5. Improvement in quality of life, decrease in left ventricular diastolic dimension, improved objective assessment of exercise tolerance, and decreased heart failure-related hospitalizations have all been well demonstrated in the adult population. Whether or not these benefits occur in younger patients is not clear.6 Since none of the major trials for CRT have included children, much is unknown about the specifics of indication, difficulties with implant, and efficacy in the pediatric population7. More recently, small case series have shown the potential for benefit for CRT in patients with congenital heart disease including those with a systemic right ventricle and single ventricle physiology. Whether long-term benefit for extending CRT therapy to children with congenital heart disease exists is unclear. There are several challenges confronting the implanter when considering CRT therapy in children, and these are summarized in Table 1. Despite these limitations in our present knowledge as to how indications, implant, and optimization of CRT devices should be amended in children, evidence is accumulating that suggests at least a similar benefit in children exists, as has been been demonstrated in adults. In children with left ventricular failure and left bundle-branch block, acute left ventricular hemodynamics has been shown to improve with biventricular stimulation8. In longerterm studies, CRT has also been demonstrated to improve effort tolerance and oxygen consumption.9-14 Isolated reports have shown an average increase in ejection fraction of 14-18% and typically correlated with a concurrent decrease in QRS duration of 20-40 ms. Improvement (decrease) in left ventricular end diastolic diameter with effective resynchronization of up to 6 mm has been reported.15 Improvement in heart failure symptoms and New York Heart Association class has also been shown anecdotally to occur in children as has been well established in adults.14,16,17 Given this rudimentary but existing evidence of CRT benefit for children with refractory heart failure symptoms, the implanting physician needs to be familiar with the idiosyncrasies of pediatric CRT. Not only must the implanter be cognizant of the
Economic journals of Russia, their characteristics and network analysis (2021)

We study economic journals published in Russia and indexed in the Russian Index of Science Citation (RISC). We analyze citations of 466 journals for 2016–2020 and compare these journals using several metrics: total citation count, Hirsch index, Impact factor RISC, and Science Index RISC. We also use network analysis for citation graphs and compare journals by centrality indices: Copeland index and two new indices: Bundle and Pivotal. We found that “Voprosy Ekonomiki” is the only journal that is among the top-5 journals for all metrics. Other top journals differ for different metrics. We noticed that some top journals have a questionable reputation and the reason why they are among the top journals is a high number of publications, which makes classical journals less influential with respect to the metrics.

[IC‐01–05]: FIRST‐IN‐HUMAN PET STUDIES WITH THE NEXT GENERATION TAU AGENT 18‐F PI‐2620 IN ALZHEIMER's DISEASE, PROGRESSIVE SUPRANUCLEAR PALSY, AND CONTROLS (2017)

Intracellular tau deposition is a key pathologic feature of Alzheimer's disease (AD) and other neurodegenerative disorders. Recently, positron emission tomography tau probes have been developed for in vivo detection of brain tau load, although quantification is challenging due to high off-target binding and slow kinetics. Further, different tau radiotracers have different affinities for tau species. PI-2620 is a novel tracer with an IC50 of 1.8 nM for tau in AD brain homogenate competition-assays and binds specifically to tau deposits in AD brain sections (Braak I-VI), Pick's, and progressive supranuclear palsy (PSP) pathologies. This first-in-human study assesses 18-F-labelled PI-2620 in AD, PSP, and healthy volunteers. In an ongoing clinical imaging study, participants diagnosed with mild Alzheimer's (AD), non-AD tauopathies (e.g. PSP), and healthy volunteers (HV) undergo dynamic PET imaging for over 3 h following 370 MBq bolus injection of 18F-PI-2620. Venous blood is obtained to characterize the kinetics of parent compound and metabolites. Initial imaging data shows robust brain uptake and fast wash-out in non-target regions with peak SUV = 4–4.5. There was no increased uptake seen in choroid plexus, striatum, amygdala, or other regions noted in first generation tau agents. In AD, focal asymmetric uptake was evident in temporal and parietal lobes, precuneus, and cingulate. SUVr time curves demonstrate a plateau at 90–100 min post injection with resultant SUVrs of 2.5–2.8.in abnormal regions, whilst HV demonstrated shorter time to secular equilibrium (60–70 min) and lower SUVrs (1.0–1.2) in comparable brain regions. Finally, PSP subjects demonstrated focal and symmetric increased uptake in the globus (SUVr=1.99–2.11) and midbrain (SUVr=2.41–2.58). Blood data confirmed fast kinetics with 20% of parent compound present at 60 min and the presence of polar metabolites. Initial PI-2620 PET first-in-human studies demonstrate excellent brain penetrance, favorable kinetics, and high target specificity with low nonspecific binding and high signal in regions of expected tau pathology.
Proline- and Arginine-Rich Peptides Constitute a Novel Class of Allosteric Inhibitors of Proteasome Activity (2003)

Substrate-specific inhibition of the proteasome has been unachievable despite great interest in proteasome inhibitors as drugs. Recent studies demonstrated that PR39, a natural proline- and arginine-rich antibacterial peptide, stimulates angiogenesis and inhibits inflammatory responses by specifically blocking degradation of IkappaBalpha and HIF-1alpha by the proteasome. However, molecular events involved in the PR39-proteasome interaction have not been elucidated. Here we show that PR39 is a noncompetitive and reversible inhibitor of the proteasome function. This effect is achieved by a unique allosteric mechanism allowing for specific inhibition of degradation of selected proteins without affecting total proteasome-dependent proteolysis. Atomic force microscopy (AFM) studies demonstrate that 20S and 26S proteasomes treated with PR39 or its derivatives exhibit serious perturbations in their structure and their normal allosteric movements. These effects are universal for proteasomes from yeast to human. The shortest functional sequence derived from PR39 still showing the allosteric inhibitory effect consists of eleven NH(2)-terminal residues containing essential three NH(2)-terminal arginines. The noncompetitive and reversible in vitro action of PR39 and its truncated derivatives is matched by the ability of the peptides to induce angiogenesis in vivo. We postulate that PR39 changes conformational dynamics of the proteasomes by interactions with the noncatalytic subunit alpha7 in a way that prevents the enzyme from cleaving the substrates of unique structural constraints.

Splenic abscess in a patient with fecal peritonitis (2007)

Splenic abscess is a rare entity normally associated with underlying diseases. We report a case of splenic abscess with large gas formation in a non-diabetic and non-immunosuppressed patient after surgery for colon perforation. The most frequent cause of splenic abscess is septic embolism arising from bacterial endocarditis. Splenic abscess has a high rate of mortality when it is diagnosed late. Computed tomography resolved any diagnostic doubt, and subsequent surgery confirmed the diagnosis.
