Polymeric Droplets on Soft Surfaces: From Neumann’s Triangle to Young’s Law (2015)

Shape deformation of polymeric droplets on gel-like surfaces is studied by using a combination of the molecular dynamics simulations and theoretical calculations. On the basis of the results of molecular dynamics simulations, we have developed a theoretical model of droplet shape deformation on elastic surfaces which takes into account surface and elastic energy contributions. Analysis of simulation results in the framework of this model shows that the equilibrium droplet shape is controlled by the dimensionless parameter γSL/GSa, where γSL is the surface tension of the substrate/liquid interface, GS is the shear modulus of the substrate, and a is the contact radius of polymeric droplet. This parameter describes crossover between Neumann’s triangle conditions for liquid droplets on liquid substrates and Young’s law for droplets on rigid substrates. In the limit when the elastocapillary length is much larger than the contact radius, γSL/GS ≫ a, we recover the Neumann’s triangle conditions for liquid droplets floating on liquid substrates. However, in the opposite limit, γSL/GS ≪ a, our model reproduces Young’s law. The model predictions are in a very good agreement with simulation results and experimental data.
Development of MEMS Receiver for the Seismic Survey (2018)

これまで地震探査で使用され続けてきたジオフォンに代わる受振器として，MEMSセンサを用いることを検討したが，民生用に使用されているMEMSセンサは感度が低く，地震探査に用いることができないため，新規開発を行った．高感度化のためには静電容量変化量を大きくする必要がある．その課題を解決するために，支える梁の形状，梁の厚さ，電極間ギャップ，スティッキング（張り付き），気体の粘性の影響，ブラウニアンノイズ等の影響をシミュレーションで確認し，周波数帯域0～250Hzにおいて感度異常の生じない設計仕様とした．センサエレメントを駆動する回路は，静電容量変化の読み取り，波形フィルタおよび出力を全てデジタルで行う方式とした．性能試験では，ノイズ評価試験を行い，ノイズレベルとして-130dB/√Hz以下を確認した．フィールド性能試験では，千葉県山武市において，測線長4kmの反射法地震探査を，試作品MEMS，ジオフォンおよび市販のMEMSセンサの3種類を用いて対比試験を行った．その結果，3種類のセンサによる反射断面は類似しており，実施時期やセンサ設置条件の違いを考慮すると，これらと同等であると考えられた．
Yield–trait performance landscapes: from theory to application in breeding maize for drought tolerance (2010)

The effectiveness of breeding strategies to increase drought resistance in crops could be increased further if some of the complexities in gene-to-phenotype (G → P) relations associated with epistasis, pleiotropy, and genotype-by-environment interactions could be captured in realistic G → P models, and represented in a quantitative manner useful for selection. This paper outlines a promising methodology. First, the concept of landscapes was extended from the study of fitness landscapes used in evolutionary genetics to the characterization of yield-trait-performance landscapes for agricultural environments and applications in plant breeding. Second, the E(NK) model of trait genetic architecture was extended to incorporate biophysical, physiological, and statistical components. Third, a graphical representation is proposed to visualize the yield-trait performance landscape concept for use in selection decisions. The methodology was demonstrated at a particular stage of a maize breeding programme with the objective of improving the drought tolerance of maize hybrids for the US Western Corn-Belt. The application of the framework to the genetic improvement of drought tolerance in maize supported selection of Doubled Haploid (DH) lines with improved levels of drought tolerance based on physiological genetic knowledge, prediction of test-cross yield within the target population of environments, and their predicted potential to sustain further genetic progress with additional cycles of selection. The existence of rugged yield-performance landscapes with multiple peaks and intervening valleys of lower performance, as shown in this study, supports the proposition that phenotyping strategies, and the directions emphasized in genomic selection can be improved by creating knowledge of the topology of yield-trait performance landscapes.
Properties of N-polar GaN films and AlGaN/GaN heterostructures grown on (111) silicon by metal organic chemical vapor deposition (2010)

Smooth N-polar GaN films and GaN/AlGaN/GaN heterostructures with properties comparable to Ga-polar GaN-on-silicon films were grown by metal organic chemical vapor deposition on (111) silicon substrates with a misorientation angle of 3.5° toward the [112¯] direction. For heterostructures with a sheet electron density of 9×1012 cm−2 an electron mobility of 1500 cm2/V s was derived for transport parallel to the surface steps which formed as a result of the substrate misorientation.
Palladium and Rhodium Complexes with Planar-Chiral Carborane Ligands (2001)

Base degradation of the prochiral 1-diphenylphosphanyl-2-phenyl-1,2-dicarba-closo-dodecaborane (1) affords the planar-chiral 7-diphenylphosphanyl-8-phenyl-7,8-dicarba-nido-undecaborate anion (2). Resolution of the racemic anion carried out using a well-established procedure, gave the internally diastereomeric palladium complexes 3R-R and 3R-S. These complexes were separated by fractional crystallization. A single-crystal X-ray analysis of 3R-R established the exo-nido bonding of the carborane ligand via the phosphorus atom and the adjacent BH group, and the (R) configuration of the carborane ligand. The enantiomerically pure anions of 2 were liberated from the diastereomerically pure palladium complexes 3R-R and 3R-S, respectively, by subsequent addition of HCl and NaCN. The exo-nido-rhodium−carborane complexes 4−8 were prepared by heating 2eR or 2eS with [Rh(COD)Cl]2 and/or a chiral chelating phosphane, such as DIOP and BINAP, under reflux. The chiral complexes were tested under enantioselective catalysis conditions such as hydrogenation of acetamidocinnamic acid, hydrogenation of ketopantolactone, and hydrosilylation of acetophenone.

Ginsenoside Rh2 Ameliorates Atopic Dermatitis in NC/Nga Mice by Suppressing NF-kappaB-Mediated Thymic Stromal Lymphopoietin Expression and T Helper Type 2 Differentiation (2019)

Ginsenosides are known to have various highly pharmacological activities, such as anti-cancer and anti-inflammatory effects. However, the search for the most effective ginsenosides against the pathogenesis of atopic dermatitis (AD) and the study of the effects of ginsenosides on specific cytokines involved in AD remain unclear. In this study, ginsenoside Rh2 was shown to exert the most effective anti-inflammatory action on thymic stromal lymphopoietin (TSLP) and interleukin 8 in tumor necrosis factor-alpha and polyinosinic: polycytidylic acid induced normal human keratinocytes by inhibiting proinflammatory cytokines at both protein and transcriptional levels. Concomitantly, Rh2 also efficiently alleviated 2,4-dinitrochlorobenzene-induced AD-like skin symptoms when applied topically, including suppression of immune cell infiltration, cytokine expression, and serum immunoglobulin E levels in NC/Nga mice. In line with the in vitro results, Rh2 inhibited TSLP levels in AD mice via regulation of an underlying mechanism involving the nuclear factor κB pathways. In addition, in regard to immune cells, we showed that Rh2 suppressed not only the expression of TSLP but the differentiation of naïve CD4+ T-cells into T helper type 2 cells and their effector function in vitro. Collectively, our results indicated that Rh2 might be considered as a good therapeutic candidate for the alternative treatment of AD.
Hydrodynamic Assessment of a Small Intestinal Submucosa Tubular Aortic Valve (2020)

Objective: For young children with critical valve defects, and for older patients who are contra-indicated for receiving mechanical and bioprosthetic valves, treatment options are extremely limited. The purpose of this study was to determine whether tubular porcine small intestinal submucosa (PSIS) bio-scaffold valves can facilitate robust aortic valvular hydrodynamic function and serves as a potential treatment option for the aforementioned patient sub-sets. Methods: A 26-mm PSIS tubular valve (CorMatrix Cardiovascular Inc., Roswell, GA) was sutured to a custom, 3-D printed valve holder along its ring and its three posts on the distal end (120o separation distance; Fig. 1A). Hydrodynamic testing was performed using a pulse duplicator system (Vivitro Labs Inc., Victoria, BC, Canada) filled with 0.9% saline solution, with the PSIS valve mounted in the aortic position. A flow probe was affixed between the aortic and ventricular chamber and pressure transducers were inserted in the atrial, ventricular, and aortic locations (AMpack, Vivitro Labs). Tests utilized a stroke volume of 71.4 mL, heart rate of 70 BPM, and input flow waveform comprising of a 35% systolic-65% diastolic configuration (S35 Waveform, Vivitest software, Vivitro Laboratories). Results: Tests revealed a root mean square volumetric flow rate (QRMS) of 182 mL/s, an effective orifice area (EOA) of 0.73 cm2, transvalvular pressure gradient of 27.64 mmHg and a regurgitation factor (RF) of 9%. While the pressure gradient was higher than bioprosthetic valves previously tested in our laboratory under similar conditions, ~15.9 mmHg, it was substantially less than clinical critical aortic valve stenosis (>40 mmHg; Lancellotti P, Seisyou K., J Echocardiog, 12, pp12-16, 2014) (Fig. 1B). Conclusions: The tubular PSIS aortic valve may facilitate robust hydrodynamic valve function and could also serve as a scaffold for de novo valvular tissue growth by the host after implantation.

Reaction yields of diamondoid synthesis by plasmas generated in supercritical xenon (2013)

Diamondoids are sp3-hybridized carbon nanomaterials that hold promise for application in biotechnology, medicine, and opto- and nanoelectronics. While difficult or even impossible to realize by conventional organic synthesis methods, the synthesis of larger diamondoids was demonstrated by plasmas generated in supercritical fluids, however, the reaction mechanisms that lead to their formation are not clear. Here, we investigated the synthesis of diamondoids from adamantane and present a simple model that predicts the reaction rates of diamantane, triamantane, and tetramantane. The diamondoids were synthesized by micro dielectric barrier discharges arranged in arrays, generated at frequencies of 7 kHz and applied voltages of 5 − 10 kVp−p in supercritical xenon (pressure 5.56 − 8.22 MPa, temperature 290.0 − 310.2 K). The collected samples were analyzed and quantified by gas chromatography - mass spectrometry measurements. The reaction yields of diamantane increase with increasing precursor density and longer reaction times. Experimental data also suggests a stepwise reaction of higher diamondoids from lower diamondoids, and predicts lower reaction rates for higher diamondoids when compared to lower diamondoids.
Hexagonally‐closed‐packed micro‐light‐emitting diodes (2006)

Abstract A micro‐light‐emitting diode array, based on a hexagonal closed‐packed structure is presented. Compared to previous designs such as microdisk and microring, the packing density of individual hexagonal elements can be increased to over 80% to minimize wastage of junction area. The increased sidewall area provides additional light extraction pathways. The hexagonal LED emits twice as much light compared to a conventional broad‐area LED with equal junction area, and 50% more light than a microdisk array LED. The marked improvement in efficiency makes the additional processing step worthwhile. (© 2006 WILEY‐VCH Verlag GmbH &amp; Co. KGaA, Weinheim)

Time-Varying Graph Signal Inpainting Via Unrolling Networks (2021)

We propose an interpretable graph neural network based on algorithm unrolling to reconstruct a time-varying graph signal from partial measurements. The proposed graph unrolling networks expand algorithm unrolling to the graph-time domain and provide an interpretation of the architecture design from a signal processing perspective. We unroll an iterative inpainting algorithm by mapping each iteration to a single network layer. The feed-forward process is thus equivalent to iteratively reconstructing a time-varying graph signal. We train this network through unsupervised learning, where the input time-varying graph signal is used to supervise the training. By leveraging the learning ability of neural networks, we adaptively capture appropriate priors from input data, instead of manually choosing signal priors. To validate the proposed methods, we conduct experiments on three real-world datasets and demonstrate that our networks achieve smaller reconstruction errors than conventional inpainting algorithms and state-of-the-art graph neural networks.
Haftungsbeschränkung der digitalen Signatur durch einen Commitment Service (1999)

Der Commitment Service ist ein Notariatsdienst auf einem offenen Netz, z.B. dem Internet. Er enthält eine Registrierungsinstanz für Benutzer und deren öffentliche Schlüssel, und basiert auf einem speziellen Vertrag mit dem Benutzer. Der Commitment Service erlaubt es einem registrierten Benutzer, dem Geschäftspartner eine garantierte Zusicherung zu übermitteln. Eine solche Zusicherung soll auch dann gelten, wenn der Benutzer behauptet, daß seine digitale Signatur gefälscht und die Zusicherung erschlichen wurde. Auf diese Weise kann eine Zusicherung z. B. die Übernahme einer bestimmten Haftung für Schaden beim Empfänger bedeuten für den Fall, daß die digitale Signatur z.B. nach einer Kompromittierung widerrufen wird. Der Commitment Service nimmt hier die Rolle als Zeuge für die Zusicherung (nicht für die digitale Signatur!) wahr und kontrolliert, daß nicht mehr bezeugte Zusicherungen ausgegeben werden als über ein Volumen, das mit dem Benutzer zu Beginn vereinbart wurde. So begrenzt er den schlimmsten Fall für den Benutzer, falls dessen digitale Signatur z.B. durch ein Trojanisches Pferd gefälscht wird. Gleichzeitig ermöglicht er dem Empfänger, sich auf die Zusicherung zu verlassen. Es wird gezeigt, wie dieser Service als Zwischenlösung zum Schutz des Benutzers sowie dessen Geschäftspartners eingesetzt werden kann, solange es noch keine geregelte rechtsverbindliche digitale Signatur gibt, die nicht nur kryptographisch, sondern auch in ihrem Umfeld sicher ist gegen Angriffe. Falls letzteres Problem nicht genügend in Signaturgesetzen und deren Anforderungen berücksichtigt werden sollte, dann könnte sich die vorgeschlagene Lösung auch als Alternative zu einer gesetzlich geregelten digitalen Signatur durchsetzen, indem sie eine vertraglich festgelegte Rechtsverbindlichkeit bietet und gewährleistet, daß ein vom Benutzer definiertes Haftungslimit nicht überschritten wird. Weiterhin kann der vorgestellte Dienst auch allgemeiner genutzt werden, z.B. um nichtabstreitbare Gutscheine zu übermitteln.

Recordings of the EAS EMG can be used to detect robustly the onset of neurogenic detrusor contractions. The EAS EMG is a suitable signal to control closed-loop inhibitory electrical stimulation to maintain urinary continence.
Nickel(II) Heterocyclic Carbene Complexes as Catalysts for Olefin Dimerization in an Imidazolium Chloroaluminate Ionic Liquid (2001)

Nickel(II) heterocyclic carbene complexes of the formula NiI2(carbene)2 (carbene = 3-methyl-1-propylimidazolin-2-ylidene (1), 1-butyl-3-methylimidazolin-2-ylidene (2), 1-isopropyl-3-methylimidazolin-2-ylidene (3), 1,3-diisopropylimidazolin-2-ylidene (4)) have been prepared and fully characterized by both spectroscopic methods and single-crystal X-ray structure analysis. All complexes have “square-planar” nickel environments, with the donor atoms pairwise trans, all obligate, except for one of the two independent molecular types found in 2, in which, with different substituents at the nitrogen atoms, the two rotamers are observed as independent molecules in the one crystal. Complexes 1−4 were tested as catalysts for propene and 1-butene dimerization in both toluene and an imidazolium−chloroaluminate ionic liquid. While the complexes are inactive to sparingly active in toluene, highly active catalysts are produced in the ionic liquid. In all cases the complexes are more active toward 1-butene dimerization than is NiCl2(PCy3)2 in the ionic liquid. The results are interpreted in terms of catalyst stabilization by the imidazolium-based ionic liquid. In toluene the complexes decompose rapidly via reductive elimination of imidazolium cations, while in the ionic liquid no decomposition is observed. While reductive elimination of imidazolium is possible in the ionic liquid, a rapid reoxidation via addition of the solvent imidazolium cation seems possible and may prevent the formation of Ni0 deposits associated with catalyst deactivation.

<title>Effective transportation of laser radiation through the atmosphere</title> (1996)

Peculiarities of constructing adaptive optical systems for forming and transportation of laser radiation through the atmosphere are considered. Results on elaboration and testing of the elements and the adaptive schemes on the special test-bench are given. The results on investigation of real-time compensation of the atmospheric phase disturbances using the adaptive optical train with the heterodyne wavefront analyzer, the electro-optical phase corrector, and the data-processing system based on the neural network are also reported. We analyze possible means of construction of adaptive optical trains to one-channel laser radiators and multi-channel phased systems.
Motion segmentation with occlusions on the superpixel graph (2009)

We present a motion segmentation algorithm that partitions the image plane into disjoint regions based on their parametric motion. It relies on a finer partitioning of the image domain into regions of uniform photometric properties, with motion segments made of unions of such ¿superpixels¿. We exploit recent advances in combinatorial graph optimization that yield computationally efficient estimates. The energy functional is built on a superpixel graph, and is iteratively minimized by computing a parametric motion model in closed-form, followed by a graph cut of the superpixel adjacency graph. It generalizes naturally to multi-label partitions that can handle multiple motions.
On The Behaviour Of Microwave Signals In Optical Networks (1993)

In the last years, significant progress have been accomplished in the domain of optical communications such that the microwave transmission by optical carriers is now an existing system currently used. The technological advances in optical-to-electrical and electrical-to-optical conversion allows today to consider not only the simple optical transmission of microwave signals but also the processing of these signals using optical networks. For this purpose the propagation of the optical signal in a network with dimensions comparable to the wavelength of the modulating microwave signal should be studied. This requires to overcome some problems like the polarisation dependence, the dimensional effects on the modulating signals, the multimode properties of some optical components, etc., which makes the optical network fed by a microwave modulated laser beam a subject of great interest. The object of this work is to study the behaviour of the microwave modulating signal in two optical elements : the Fabry-Perot interferometer and the unbalanced Mach-Zehnder one. The two interferometers are constructed using single mode optical fibers and 3 dB directional couplers as shown in Fig. 1 a and b. The system is excited by an optical signal of wavelength λ=1.3 μm modulated by an electrical (microwave) signal of frequency between 0.3 MHz and 3 GHz. A suitable photodetector is used to extract the electrical output signal. The overall system (source, network and detector) may be considered as a microwave "device" for which we can define a microwave transfer function or, in general, microwave scattering parameters. Using the HP8702 lightwave component analyser with the HP83400A light source and the HF'83410A lightwave receiver, we have measured the characteristics of this system.
