The role of the host versus the guest in the electroluminescence degradation of PHOLEDs(Conference Presentation) (2016)

Although the electroluminescence (EL) stability of phosphorescent organic light-emitting devices (PHOLEDs) has long been known to depend on the stability of the phosphorescent guest emitter, we recently found that the host also plays an important role. More specifically, we found that interactions between excitons and polarons to result in molecular aggregation of the host material, a phenomenon that appears to play a significant role in the deterioration in efficiency with electrical aging in these devices. The question of whether it is the guest or the host that plays the more leading role in device stability becomes therefore quite relevant. In this work we present data from a comparative systematic study on various host and guest materials used in PHOLEDs. The host materials include CBP, 26DCzPPy and TAPC, and the guest materials include Ir(ppy)3, Ir(ppy)2(acac), Ir(piq)3 and FIrpic. Changes in EL and time resolved photoluminescence characteristics are used in order to understand the interplay between the host and the guest under various electrical and thermal stress conditions. Results suggest that the host plays a more dominant role in determining PHOLED stability. They also shed some light on the interplay between host and guest materials and the effect on device stability. Results from this work will be presented and analyzed.
<title>Three-dimensional image capturing and representation for multimedia ambiance communication</title> (2001)

Multimedia Ambiance Communication is as a means of achieving shared-space communication in an immersive environment consisting of an arch-type stereoscopic projection display. Our goal is to enable shared-space communication by creating a photo-realistic three-dimensional (3D) image space that users can feel a part of. The concept of a layered structure defined for painting, such as long-range, mid-range, and short-range views, can be applied to a 3D image space. New techniques, such as two-plane expression, high quality panorama image generation and setting representation for image processing, 3D image representation and generation for photo- realistic 3D image space have been developed. Also, we propose a life-like avatar within the 3D image space. To obtain the characteristics of user's body, a human subject is scanned using a CyberwareTM whole body scanner. The output from the scanner, a range image, is a good start for modeling the avatar's geometric shape. A generic human surface model is fitted to the range image. The obtained model is topologically equivalent even if our method is applied to another subject. If a generic model with motion definitions is employed, and common motion rules can be applied to all models made from the generic model.© (2001) COPYRIGHT SPIE--The International Society for Optical Engineering.

Two cases of brainstem neurocysticercosis removal: operative video (2019)

Neurocysticercosis is primarily managed with anthelminthic, antiepileptic, and corticosteroid therapies. Surgical removal of the larval cyst is indicated when associated mass effect causes neurological symptoms, as demonstrated in two cases. Cyst resection was achieved via the far lateral approach for a cervicomedullary cyst in one patient and via the subtemporal approach for a mesencephalic cyst in another. The cyst wall should be kept intact, when possible, to avoid dissemination of the inflammation-evoking contents. As the contents are usually semisolid and can be removed via suction, it is not necessary to remove the gliotic capsule or adherent portions of the cyst wall in highly eloquent locations.

A Switched-Capacitor Lossless Inductor ZCS Snubber-Assisted Series Load Resonant High Frequency Inverter with Dual Mode Pulse Modulation Scheme (2006)

In this paper, a novel type auxiliary active edge resonant snubber assisted zero current soft switching pulse modulation series load resonant inverter using IGBT power modules is proposed for cost effective consumer high-frequency induction heating (IH) appliances. Its operating principle in steady state is described by using each switching mode equivalent operating circuits. The new multi resonant high-frequency inverter with series load resonance and edge resonance can regulate its high frequency output power under a condition of a constant frequency zero current soft switching (ZCS) commutation principle on the basis of asymmetrical pulse width modulation (PWM) control scheme. The consumer brand-new IH products using proposed ZCS-PWM high-frequency inverter is evaluated and discussed as compared with conventional type inverter on the basis of experimental results. In order to extend ZCS operation ranges under a low power setting PWM as well as to improve efficiency, the high frequency pulse density modulation (PDM) strategy is demonstrated for high frequency multi resonant inverter. Its practical effectiveness is substantially proved from an application point of view
CARC15: Detection and classification of circulating platelet aggregates in patients with left ventricular assist devices by real-time image-based single-cell profiling (2023)

Background: Patients with left ventricular assist devices (LVADs) as a bridge to heart transplantation often face long waiting periods. In order to improve prognosis, stable management with fewer complications is crucial. This study aimed to retrospectively investigate the potential of circulating platelet aggregates as a surrogate marker for risk stratification and early detection of complications after LVAD implantation. Methods: Patients with LVADs who regularly attended outpatient clinics were enrolled in this study. Blood samples were taken, centrifuged, and labeled with a CD61 antibody to detect platelets and platelet aggregates using imaging flow cytometry. The area of the objects captured in images was measured by a custom MATLAB script, and the concentration of platelet aggregates was calculated to evaluate its correlation with clinical factors. Additionally, a prediction model using a convolutional neural network was used for morphological classification of platelet aggregates. The model was trained by the images of platelet aggregates from healthy volunteers in vitro using four agonists, namely, adenosine diphosphate, collagen, thrombin receptor-activating peptide-6 (TRAP-6), and U46619. Results: A total of 47 patients were included in the analysis. The concentration of platelet aggregates was 11.9 ± 10.2% (mean ± SD) and was found to have a significant correlation with the duration of LVAD support and the levels of fibrinogen degradation product and D-dimer (P < 0.05). Patients with infectious complications after LVAD implantation had significantly higher platelet aggregates (P < 0.05). The morphological classification revealed that circulating platelet aggregates from patients with LVADs were mainly categorized as platelet aggregates induced by collagen and TRAP-6. Conclusion: The study successfully demonstrated the ability to detect and classify circulating platelet aggregates in patients with LVADs. A follow-up study is currently under way to examine the use of this method in perioperative LVAD patients.
Stereo matching with linear superposition of layers (2006)

In this paper, we address stereo matching in the presence of a class of non-Lambertian effects, where image formation can be modeled as the additive superposition of layers at different depths. The presence of such effects makes it impossible for traditional stereo vision algorithms to recover depths using direct color matching-based methods. We develop several techniques to estimate both depths and colors of the component layers. Depth hypotheses are enumerated in pairs, one from each layer, in a nested plane sweep. For each pair of depth hypotheses, matching is accomplished using spatial-temporal differencing. We then use graph cut optimization to solve for the depths of both layers. This is followed by an iterative color update algorithm which we proved to be convergent. Our algorithm recovers depth and color estimates for both synthetic and real image sequences.
Magnetic Integration for Parallel Interleaved VSCs Connected in a Whiffletree Configuration (2016)

The voltage source converters (VSCs) are often connected in parallel to realize a high current rating. In such systems, the harmonic quality of the output voltage can be improved by interleaving the carrier signals of the parallel VSCs. However, an additional inductive filter is often required to suppress the circulating current that flows between the parallel interleaved VSCs. One of the ways to deal with the circulating current problem is to use the coupled inductors in a whiffletree configuration. This paper proposes the integration of the line filter inductor and the circulating current filter inductor in a single magnetic component for such systems. The fundamental frequency component of the flux is mostly confined to the limbs around which the coils are placed, whereas other parts of the magnetic structure only experiences high-frequency flux excitation. As a result, the integrated inductor can be made smaller and the power density of the overall converter system can be increased. The magnetic structure of the integrated inductor is analyzed and performance is verified by simulation and experimental studies.
Controlling aminosilane layer thickness to extend the plasma half-life of stealth persistent luminescence nanoparticles in vivo (2015)

Therapeutics and diagnostics both initiated the development and rational design of nanoparticles intended for biomedical applications. Yet, the fate of these nanosystems in vivo is hardly manageable and generally results in their rapid uptake by the mononuclear phagocyte system, i.e. liver and spleen. To overcome this essential limitation, efforts have been made to understand the influence of physico-chemical parameters on the behaviour of nanoparticles in vivo and on their ability to be uptaken by phagocytic cells. Notably, polyethylene glycol grafting and precise control of its density have not only been shown to prevent protein adsorption on the surface of nanoparticles, but also to significantly reduce macrophage uptake in vitro. In this article, we suggest the use of persistent luminescence to study the influence of another parameter, aminosilane layer thickness, on both in vitro protein adsorption and in vivo biodistribution of stealth persistent nanophosphors.
Polarization-dependent interference between dipole moments of a resonantly excited quantum dot (2016)

Resonant photoluminescence excitation (RPLE) spectra of a neutral InGaAs quantum dot show an unconventional line-shape that depends on the detection polarization. We characterize this phenomenon by performing polarization-dependent RPLE measurements and simulating the measured spectra with a 3-level quantum model. This analysis enables us to extract the coherence between the two exciton states from the measured spectra. The good agreement between the data and model indicates that the interference between coherent scatterings from both fine structure split exciton states is the key to understanding this phenomenon.
IRA2 , a Second Gene of Saccharomyces cerevisiae That Encodes a Protein with a Domain Homologous to Mammalian ras GTPase-Activating Protein (1990)

The IRA1 gene is a negative regulator of the RAS-cyclic AMP pathway in Saccharomyces cerevisiae. To identify other genes involved in this pathway, we screened yeast genomic DNA libraries for genes that can suppress the heat shock sensitivity of the ira1 mutation on a multicopy vector. We identified IRA2, encoding a protein of 3,079 amino acids, that is 45% identical to the IRA1 protein. The region homologous between the IRA1 protein and ras GTPase-activating protein is also conserved in IRA2. IRA2 maps 11 centimorgans distal to the arg1 locus on the left arm of chromosome XV and was found to be allelic to glc4. Disruption of the IRA2 gene resulted in (i) increased sensitivity to heat shock and nitrogen starvation, (ii) sporulation defects, and (iii) suppression of the lethality of the cdc25 mutant. Analysis of disruption mutants of IRA1 and IRA2 indicated that IRA1 and IRA2 proteins additively regulate the RAS-cyclic AMP pathway in a negative fashion. Expression of the IRA2 domain homologous with GAP is sufficient for complementation of the heat shock sensitivity of ira2, suggesting that IRA down regulates RAS activity by stimulating the GTPase activity of RAS proteins.
Photoinduzierte Zersetzung von Aryldiazoniumsalzen durch Metalloxalate (1983)

Photoinduced Decomposition of Arene Diazonium Salts by Metal Oxalates Arene diazonium salts were decomposed by the irradiation of K 3 [Fe(oX) 3 ] and K 3 [Co(ox) 3 ]. The dediazonation is caused by electron transfer reactions between ·CO ‐ 2 and in the case of the former complex also by [Fe(ox) 2 ] 2‐ ‐species. As intermediates aryl radicals were found by spin trapping with nitroso durene. The dediazonation quantum yields (0,15‐‐1,21) depend on the reduction potentials of the salts and on the oxalate concentration. By electron acceptor substituted diazonium salts the values are the same as those of the K 3 [Fe(ox) 3 ]‐actinometer. In the case of p‐dialkylaminobenzene diazonium salt‐types an electron transfer takes places with ·CO ‐ 2 only whereas the reaction with [Fe(ox) 2 ] 2− is neglectable. A Hammett‐correlation for the electron transfer of Fe(II)‐species with a ϱ‐value of 1.7 was found. The investigated systems are efficient initiators of the photopolymerization.
Holographic imaging of pulsatile microvascular blood flow in the cerebral cortex (2016)

Imaging of microvascular blood flow in the exposed cerebral cortex of a mouse was achieved by laser holographic interferometry with a 50 kHz framerate camera. Videos of local Doppler contrasts were rendered numerically by Fresnel transformation and short-time Fourier transform analysis of off-axis holograms. Pulsatile blood flow contrasts in superficial blood vessels were revealed with a spatial resolution of 10 microns and a temporal resolution of 20 ms.
Health Effects of Salicylates in Foods and Drugs (2009)

There is much (renewed) interest about the effects of salicylates on food intolerance, attention-deficit disorders, and cardiovascular disease. Current evidence for the efficacy of salicylate-elimination diets in the treatment of attention-deficit disorders and hyperactivity is weak, and further investigation is required on the relationship between salicylates and cardiovascular disease.

IEEE Workshop on Real-Time 3D Sensors and Their Use (2005)

The past few years have seen improvements in the frame rate, accuracy, cost, and size of 3D sensors, including systems based on stereo vision, time-of-flight, structured light, and depth-from-X methods. These exciting developments have sparked increasing interest in industry and academia in the challenges and opportunities afforded by real-time 3D sensing. Applications such as tracking, recognition, and scene understanding may become more robust and more feasible thanks to these sensors.
Analysis of poling induced cracking in thick walled cylinders (2010)

Stresses and electric fields induced in the poling processes of both polycrystalline and single crystal thick walled cylinders are investigated and compared using a finite element analysis together with a micromechanical ferroelectric constitutive law. The analysis reveals that the polarization process begins at the inner diameter and spreads outward through the cylinder as the applied electric potential is increased. The piezoelectric strain and the remnant strain produce strain fields that are not compatible with the geometry. In the single crystal material the poling is not uniform. It is affected by the angle between the crystal orientation and the electric field direction.
Addressing the Issue of Microplastics in the Wake of the Microbead-Free Waters Act—A New Standard Can Facilitate Improved Policy (2017)

The United States Microbead-Free Waters Act was signed into law in December 2015. It is a bipartisan agreement that will eliminate one preventable source of microplastic pollution in the United States. Still, the bill is criticized for being too limited in scope, and also for discouraging the development of biodegradable alternatives that ultimately are needed to solve the bigger issue of plastics in the environment. Due to a lack of an acknowledged, appropriate standard for environmentally safe microplastics, the bill banned all plastic microbeads in selected cosmetic products. Here, we review the history of the legislation and how it relates to the issue of microplastic pollution in general, and we suggest a framework for a standard (which we call "Ecocyclable") that includes relative requirements related to toxicity, bioaccumulation, and degradation/assimilation into the natural carbon cycle. We suggest that such a standard will facilitate future regulation and legislation to reduce pollution while also encouraging innovation of sustainable technologies.

All-JJ Logic Based on Bistable JJs (2023)

The all-JJ logic family is a promising area and power efficient, scalable single flux quantum (SFQ) technology for application to exascale supercomputers. All-JJ superconductive logic is based on a superconductor-ferromagnet-superconductor (SFS) bistable JJ, enabling nanometer feature sizes in VLSI complexity superconductive systems. In this paper, a mechanical analogy is proposed to describe the dynamic behavior of these bistable JJs. Novel all-JJ logic gates, such as TFF, DFF, OR, AND, and NOT gates, are presented here. All-JJ circuits are composed of bistable JJs, standard JJs, and bias currents, not requiring large inductors within the storage loops. All-JJ logic cells exhibit less delay and power than standard SFQ cells with the same critical current density. All-JJ systems can operate at high frequencies due to the small capacitance of the SFS JJ. A complex all-JJ circuit from the suite of ISCAS'85 benchmark circuits is also characterized. This complex all-JJ circuit exhibits less delay and power as compared to standard SFQ logic. The bias current in a conventional benchmark circuit and all-JJ benchmark circuit is, respectively, 22 mA and 13 mA. The delay of each cell within the conventional benchmark circuit and all-JJ benchmark circuit is, respectively, approximately 20 and 8 ps. A parasitic inductance in series with the JJs disturbs the current distribution within the all-JJ circuits while degrading the margins. To suppress the effects of this parasitic inductance on SFS JJs, small linear inductors are added to manage the current distribution and improve the parameter margins.

A Study of Advanced High Loaded Transonic Turbine Airfoils (2004)

The development of high performance turbine airfoils has been investigated under the condition of a supersonic exit Mach number. In order to obtain a new aerodynamic design concept for a high loaded turbine rotor blade, we employed an evolutionary algorithm for numerical optimization. The target of the optimization method, which is called evolution strategy (ES), was the minimization of the total pressure loss and the deviation angle. The optimization process includes the representation of the airfoil geometry, the generation of the grid for a blade-to-blade CFD analysis, and a 2D Navier-Stokes solver with a low-Re k-ε turbulence model in order to evaluate the performance. Some interesting aspects, for example, a double shock system, an early transition and a re-distribution of aerodynamic loading on blade surface, observed in the optimized airfoil, are discussed. The increased performance of the optimized blade has been confirmed by detailed experimental investigation, using conventional probes, hot-films and L2F system.

Abstract
Macrophage migration inhibitory factor mediates the antidepressant actions of voluntary exercise (2012)

Voluntary exercise is known to have an antidepressant effect. However, the underlying mechanism for this antidepressant action of exercise remains unclear, and little progress has been made in identifying genes that are directly involved. We have identified macrophage migration inhibitory factor (MIF) by analyzing existing mRNA microarray data and confirmed the augmented expression of selected genes under two experimental conditions: voluntary exercise and electroconvulsive seizure. A proinflammatory cytokine, MIF is expressed in the central nervous system and involved in innate and adaptive immune responses. A recent study reported that MIF is involved in antidepressant-induced hippocampal neurogenesis, but the mechanism remains elusive. In our data, tryptophan hydroxylase 2 (Tph2) and brain-derived neurotrophic factor (Bdnf) expression were induced after MIF treatment in vitro, as well as during both exercise and electroconvulsive seizure in vivo. This increment of Tph2 was accompanied by increases in the levels of total serotonin in vitro. Moreover, the MIF receptor CD74 and the ERK1/2 pathway mediate the MIF-induced Tph2 and Bdnf gene expression as well as serotonin content. Experiments in Mif(-/-) mice revealed depression-like behaviors and a blunted antidepressant effect of exercise, as reflected by changes in Tph2 and Bdnf expression in the forced swim test. In addition, administration of recombinant MIF protein produced antidepressant-like behavior in rats in the forced swim test. Taken together, these results suggest a role of MIF in mediating the antidepressant action of exercise, probably by enhancing serotonin neurotransmission and neurotrophic factor-induced neurogenesis in the brain.
