Electrical analysis of hysteresis in solution processed silicon nanowire field effect transistors (2015)

Silicon nanowires (Si NW) are ideal candidates for solution processable field effect transistors (FETs). The interface between the nanowire channel and the gate dielectric plays a crucial role in the FET performance, and it can be responsible for unwanted effects such as hysteresis of the I-V characteristics due to threshold voltage shift when the gate voltage is applied. Using gate-voltage bias stress measurements we show that a large hysteresis of up to 40V in Si NW FETs with SiO2 dielectric is mainly due to the holes traps at the nanowire/SiO2 interface. An approach for reducing this hysteresis to just 2.5V using solution processable fluoropolymer dielectric Cytop in the top-gate configuration is demonstrated. Experimental results suggest that the density of surface traps in Si nanowire transistors is dictated mainly by the nature of the dielectric layer. The influence of the gate dielectric was studied by assessing the field effect transport behaviour of a representative double gate FETs based on SiO2 bottom dielectric and top Cytop dielectric layer. Such devices were characterised, revealing an order of magnitude higher hole traps density at the nanowire/SiO2 interface (1x10^13cm-2) compared to that of nanowire/fluoropolymer interface (7.5x10^11cm-2).
Repeatability Enhancements of Traffic Simulator by Introduction of Traffic Flow Compensation Methods (2012)

A traffic simulator is one of the most effective tools to estimate effects of traffic management and traffic enforcement such as new road construction, detour route guidance for avoidance of traffic accident/earthwork or emergency signal control in the event of a natural disaster. And the aim of simulation is estimation of an assumed situation, and the most important index is the congestion length on the network. Because when there is no congestion length on the roads, the travel time does not increase so much, even if the traffic volume increases. However, there are many difficulties in making simulator results reproduce the actual traffic flow in terms of traffic volume, especially congestion length and travel time. Therefore, the main data and parameters used in a simulator such as OD (Origin Destination) data and flow rate can be tuned only by an experienced engineer and it takes much time. Moreover, this parameter might not be applicable to other analysis. That’s why the techniques of automatic tuning are required. This paper explains one of the repeatability enhancement techniques. The algorithm has been installed to SOUND traffic simulator and it has been utilized at the Traffic Control Center in Tokyo since April 2011.
<i>In Vivo</i> Raman Study of the Living Rat Esophagus and Stomach Using a Micro-Raman Probe under an Endoscope (2007)

A small endoscope system equipped with a micro Raman probe is developed for in vivo Raman measurements in living rats. The measurements are done under anesthesia and artificial respiration to minimize the impact on the rats. Raman spectra of living rat esophagus and stomach are successfully measured. Our results suggest that the Raman spectra reflect subsurface tissue structure that cannot be distinguished in the endoscope image. After the experiments, rats recover without any aftereffects. It is verified that the Raman measurement using the present system is safe and noninvasive for rats.
Chondroitin sulfate A is a cell surface receptor for Plasmodium falciparum-infected erythrocytes. (1995)

Adherence of Plasmodium falciparum-infected erythrocytes to cerebral postcapillary venular endothelium is believed to be a critical step in the development of cerebral malaria. Some of the possible receptors mediating adherence have been identified, but the process of adherence in vivo is poorly understood. We investigated the role of carbohydrate ligands in adherence, and we identified chondroitin sulfate (CS) as a specific receptor for P. falciparum-infected erythrocytes. Parasitized cells bound to Chinese hamster ovary (CHO) cells and C32 melanoma cells in a chondroitin sulfate-dependent manner, whereas glycosylation mutants lacking chondroitin sulfate A (CSA) supported little or no binding. Chondroitinase treatment of wild-type CHO cells reduced binding by up to 90%. Soluble CSA inhibited binding to CHO cells by 99.2 +/- 0.2% at 10 mg/ml and by 72.5 +/- 3.8% at 1 mg/ml, whereas a range of other glycosaminoglycans such as heparan sulfate had no effect. Parasite lines selected for increased binding to CHO cells and most patient isolates bound specifically to immobilized CSA. We conclude that P. falciparum can express or expose proteins at the surface of the infected erythrocyte that mediate specific binding to CSA. This mechanism of adherence may contribute to the pathogenesis of P. falciparum malaria, but has wider implications as an example of an infectious agent with the capacity to bind specifically to cell-associated or immobilized CS.
Source code with cost as a nonuniform random number generator (2000)

We show that an optimal source code with a cost function for code symbols can be regarded as a random number generator generating a random sequence (not necessarily a sequence of fair coin bits) as the target distribution in the sense that the normalized conditional divergence between the distribution of the generated codeword distribution and the target distribution vanishes as the block length tends to infinity.
FlexFlow: A Flexible Dataflow Accelerator Architecture for Convolutional Neural Networks (2017)

Convolutional Neural Networks (CNN) are very computation-intensive. Recently, a lot of CNN accelerators based on the CNN intrinsic parallelism are proposed. However, we observed that there is a big mismatch between the parallel types supported by computing engine and the dominant parallel types of CNN workloads. This mismatch seriously degrades resource utilization of existing accelerators. In this paper, we propose a flexible dataflow architecture (FlexFlow) that can leverage the complementary effects among feature map, neuron, and synapse parallelism to mitigate the mismatch. We evaluated our design with six typical practical workloads, it acquires 2-10x performance speedup and 2.5-10x power efficiency improvement compared with three state-of-the-art accelerator architectures. Meanwhile, FlexFlow is highly scalable with growing computing engine scale.
Hydrothermal Synthesis of Single Crystalline (K,Na)NbO<sub>3</sub> Powders (2007)

Abstract (K 1– x Na x )NbO 3 ( x = 0.01, 0.24, 0.89, 0.91, 0.99) single crystalline powders with perovskite structure were synthesized by a hydrothermal method with Nb 2 O 5 in a mixed solution of KOH and NaOH at 220 °C for 24 h. XRD investigations showed that the structure of the synthesized (K 1– x Na x )NbO 3 ceramics changed from a KNbO 3 ‐type orthorhombic phase (space group Bmm 2) to a NaNbO 3 ‐type monoclinic phase (space group Pm ) with the increase of Na content. The present results confirmed that (K 1– x Na x )NbO 3 exhibited a morphotropic phase boundary (MPB) at around 50 %K separating the orthorhombic phase and monoclinic phase. FE‐SEM images showed that the morphological structures of niobates were cubes and nanofingers. The TEM image and the selected area electron diffraction pattern of (K 0.01 Na 0.99 )NbO 3 showed the as‐synthesized powder was single crystalline and indexed to be monoclinic. The phase evolution of the products in the hydrothermal route revealed that the hydrothermal synthesis of (K 1– x Na x )NbO 3 underwent two steps, where an intermediate product (K 8–8 x Na 8 x )Nb 6 O 19 · n H 2 O was found in the early stage and then pure (K 1– x Na x )NbO 3 was obtained after another 30 min of hydrothermal treatment.(© Wiley‐VCH Verlag GmbH & Co.

Analysis of<i>in vitro</i>binding of U1-A protein mutants to U1 snRNA (1991)

Despite the great sequence similarity between U1A and U2B", both proteins do have a difference in RNA binding specificity and in the way they bind to their cognate RNAs. The U1A protein is able to bind in vitro U1 RNA independently of other factors. The U2B" protein binds specifically to U2 RNA in the presence of the U2A' protein only. We have compared the effect on RNA binding of multiple double point mutations at analogous positions in the U1A and U2B" protein. The results obtained show that amino acids at almost all of the analogous positions tested in U1A and U2B" have a comparable qualitative effect on RNA binding although the quantitative effect of mutations on U2B" is more severe than on U1A. Using U1A mutants with internal duplications a distinct area of the RNP motif of the U1A protein was identified which appears not to be directly involved in U1 RNA binding. In addition, roles of the highly conserved RNP1 and RNP2 sequences of the N-terminal RNP motif of the U1A protein, are investigated by replacing them with the analogous U1-70K sequences.
Multi-environment software testing on the grid (2006)

We propose a solution to improve the confidence on the correctness of applications designed to be executed in heterogeneous environments, like a grid. Our solution is motivated by the observation that the traditional ways to qualify test processes are based on code coverage metrics. We believe that this approach is not adequate when dealing with applications that can (and do) fail when interacting with heterogeneous execution environments. Besides code coverage, tests must also cover possible environments. As a solution we propose the utilization of InGriD to describe and deploy test environments and GridUnit to coordinate and monitor the execution of test sets. By combining these two solutions we provide a cost effective way to introduce environmental coverage to our test suites, which is complementary and orthogonal to traditional code coverage metrics. As a case study, we have shown how our solution could be applied to help testing a grid application called MyPhotoGrid, which uses the grid to parallelize the generation of large photograph albums.

On the Phase Reduction and Response Dynamics of Neural Oscillator Populations (2004)

We undertake a probabilistic analysis of the response of repetitively firing neural populations to simple pulselike stimuli. Recalling and extending results from the literature, we compute phase response curves (PRCs) valid near bifurcations to periodic firing for Hindmarsh-Rose, Hodgkin-Huxley, FitzHugh-Nagumo, and Morris-Lecar models, encompassing the four generic (codimension one) bifurcations. Phase density equations are then used to analyze the role of the bifurcation, and the resulting PRC, in responses to stimuli. In particular, we explore the interplay among stimulus duration, baseline firing frequency, and population-level response patterns. We interpret the results in terms of the signal processing measure of gain and discuss further applications and experimentally testable predictions.
UAV vision: Feature based accurate ground target localization through propagated initializations and interframe homographies (2012)

Our work presents solutions to two related vexing problems in feature-based localization of ground targets in Unmanned Aerial Vehicle (UAV) images: (i) A good initial guess at the pose estimate that would speed up the convergence to the final pose estimate for each image frame in a video sequence; and (ii)Time-bounded estimation of the position of the ground target. We address both these problems within the framework of the Iterative Closest Point (ICP) algorithm that now has a rich tradition of usage in computer vision and robotics applications. We solve the first of the two problems by frame-to-frame propagation of the computed pose estimates for the purpose of the initializations needed by ICP. The second problem is solved by terminating the iterative estimation process at the expiration of the available time for each image frame. We show that when frame-to-frame homography is factored into the iterative calculations, the accuracy of the position calculated at the time of bailing out of the iterations is nearly always sufficient for the goals of UAV vision.
Targeting antioxidant pathways with ferrocenylated N-heterocyclic carbene supported gold(<scp>i</scp>) complexes in A549 lung cancer cells (2015)

Ferrocene containing <i>N</i>-heterocyclic carbene (NHC) ligated gold(I) complexes of the type [Au(NHC)<sub>2</sub>]<sup>+</sup> were prepared and found to be capable of regulating the formation of reactive oxygen species (ROS) via multiple mechanisms. Single crystal X-ray analysis of bis(1-(ferrocenylmethyl)-3-mesitylimidazol-2-ylidene)-gold(I) chloride (<b>5</b>) and bis(1,3-di(ferrocenylmethyl)imidazol-2-ylidene)-gold(I) chloride (<b>6</b>) revealed a quasi-liner geometry around the gold(I) centers, (i.e., the C<b>-</b>Au<b>-</b>C bond angle were measured to be ~177° and all the Au<b>-</b>C<sub>carbene</sub> bonds distances were in the range of 2.00 (7) - 2.03 (1) Å). A series of cell studies indicated that cell proliferation inhibition and ROS generation were directly proportional to amount of ferrocene contained within the [Au(NHC)<sub>2</sub>]<sup>+</sup> complexes (IC<sub>50</sub> of <b>6 < 5 <</b> bis(1-benzyl-3-mesitylimidazol-2-ylidene)-gold(I) chloride (<b>4</b>)).

Sources of inhibin in early pregnancy. (1995)

Inhibin is a glycoprotein which suppresses the release of follicle stimulating hormone (FSH) from the pituitary. Plasma immunoreactive inhibin levels during pregnancy have been reported to be higher than those during the normal menstrual cycle. In the present study, we investigated the cellular localization of inhibin alpha-, beta A-, and beta B-subunits in the human corpus luteum and placenta during early pregnancy. Luteal cells and theca luteal cells in the corpus luteum of pregnancy exhibited positive staining for all three inhibin subunits. We also observed positive staining with antisera against each inhibin subunit in the syncytiotrophoblast, but not in the cytotrophoblast, in the villi during early pregnancy. The staining with antisera against inhibin alpha- and beta A-subunits was clearly observed, whereas the staining for the beta B-subunit was faint. These results suggest that the gestational corpus luteum and the villous tissue may be major sources of inhibin during early pregnancy.
On the Use of Analytical Target Cascading and Collaborative Optimization for Complex System Design (2005)

1 Abstract The methods of analytical target cascading (ATC) and collaborative optimization (CO) are studied with respect to their intended use and applicability. ATC was initially developed as a product development tool, while CO evolved from eorts to coordinate multidisciplinary analyses using a multidisciplinary design optimization (MDO) formulation. ATC and CO are used typically to solve object-based and discipline-based decomposed system optimization problems, respectively. Their mathematical formulations appear to be similar although they were developed with dierent motivations. The article defines and compares terminologies for each approach and shows that each has unique applicability and solution process. Two new analytical example problems are employed to illustrate the distinctions between ATC and CO. The first example elucidates how each method can be used to solve the same design problem. The second example uses a new optimization formulation, nested ATC-MDO, to illustrate their complementary nature. In this formulation a system is partitioned by object, and objects are partitioned by discipline. ATC coordinates the design of system elements and an MDO method, such as CO, coordinates the multidisciplinary design of an element. The formulation maps well to organizational matrix structures. The overall study demonstrates the benefits of using complementary solution strategies in solving complex system optimization problems.
The Comparative Crevice Corrosion Resistance of Co‐Cr Base Surgical Implant Alloys (1976)

Different electrochemical and direct immersion tests were used to compare the relative crevice corrosion resistance of currently used or recommended nontitanium surgical implant alloys. Measurement of the anodic corrosion current vs. time of creviced specimens in deaerated isotonic salt solution at 37°C and in a solution at a series of constant applied potentials lying in the passive range of the alloys provided the same comparative rating of the different alloys as potential‐time measurements as well as direct immersion tests. According to the tests, recently developed stronger wrought versions of the Co‐Cr‐Mo‐C alloy H.S. 21 (modified Vitallium) and a wrought Co‐20Cr‐10Mo alloy were found to possess greater crevice corrosion resistance in both solutions than as‐cast H.S. 21 and wrought alloys such as H.S. 25, M.P. 35N., Elgilloy, and 316L stainless steel.

Upgrading Light Hydrocarbons via Tandem Catalysis: A Dual Homogeneous Ta/Ir System for Alkane/Alkene Coupling (2013)

Light alkanes and alkenes are abundant but are underutilized as energy carriers because of their high volatility and low energy density. A tandem catalytic approach for the coupling of alkanes and alkenes has been developed in order to upgrade these light hydrocarbons into heavier fuel molecules. This process involves alkane dehydrogenation by a pincer-ligated iridium complex and alkene dimerization by a Cp*TaCl2(alkene) catalyst. These two homogeneous catalysts operate with up to 60/30 cooperative turnovers (Ir/Ta) in the dimerization of 1-hexene/n-heptane, giving C13/C14 products in 40% yield. This dual system can also effect the catalytic dimerization of n-heptane (neohexene as the H2 acceptor) with cooperative turnover numbers of 22/3 (Ir/Ta).

Sweeping Preconditioner for the Helmholtz Equation: Moving Perfectly Matched Layers (2011)

This paper introduces a new sweeping preconditioner for the iterative solution of the variable coefficient Helmholtz equation in two and three dimensions. The algorithms follow the general structure of constructing an approximate factorization by eliminating the unknowns layer by layer starting from an absorbing layer or boundary condition. The central idea of this paper is to approximate the Schur complement matrices of the factorization using moving perfectly matched layers (PMLs) introduced in the interior of the domain. Applying each Schur complement matrix is equivalent to solving a quasi-1D problem with a banded factorization in the 2D case and to solving a quasi-2D problem with a multifrontal method in the 3D case. The resulting preconditioner has linear application cost, and the preconditioned iterative solver converges in a number of iterations that is essentially independent of the number of unknowns or the frequency. Numerical results are presented in both two and three dimensions to demonstrate the efficiency of this new preconditioner.
S–S bonds are not required for the sonochemical formation of proteinaceous microspheres: the case of streptavidin (2002)

Proteinaceous microspheres can be prepared using the sonochemical method. However, it is known that these proteins should possess at least one cysteine residue in order to obtain stable microspheres using this method. In the present study, we have produced streptavidin microspheres, using the sonochemical method, from streptavidin, which does not have any cysteine residues.
Hacia un perspectivismo hermenéutico en Leibniz (2021)

There is a long tradition of hermeneutic philosophers who have investigated Leibniz’s philosophy, and also several Leibnizian scholars who have dealt with Heideggerian thought. In this text we propose the thesis that there is a certain convergence between the hermeneutic conception of philosophy (M. Heidegger) and some of Leibniz’s ideas. The result is that there are at least three ideas that, in different formulations, are shared by both philosophers: 1) there is no pure knowledge, knowledge is always circumstantial. This is expressed by Heidegger in the notion of "hermeneutic situation" and by Leibniz with the concept of "notio completa". 2) Heidegger makes a "turn towards facticity" around the notion of "hermeneutic situation". Leibniz also makes a certain "turn towards facticity" concentrated on the notion of "corporeality". This element is not found in Heideggerian thought. 3) Understanding is also self-understanding. For Leibniz development is an unfolding and self-knowledge process of the monadic subject. For Heidegger understanding the world is also a process of self-knowledge of Dasein. Thus Leibniz outlines the "spirit" of hermeneutics in the sense that perspectivism is a form of interpretation.
