ENERGY EFFICIENT HYBRID PROCESSES FOR ETHANOL DEHYDRATION: A COMPARISON OF BENCHMARK AND MEMBRANE ASSISTED CONFIGURATIONS (2010)

One of the most promising processes for ethanol dewatering are hybrid separations consisting from different combinations of distillation with adsorption and/or vapour permeation. This paper presents a detailed process analysis showing the influence of decisive parameters on important target variables. The advanced mathematical models have been used for determination of optimal process configuration while using evolutionary algorithms.
A calcium requirement for movement of cultured cells (1979)

When calcium is removed from culture medium, motility of cultured cells is decreased. The effect is rapid, reversible and pronounced. Decreased motility is observed with normal mouse Balb/c 3T3 cells, mouse L929 cells, rat kidney fibroblasts and chick embryo fibroblasts. The calcium dependence of movement can be observed both with individual cells and with the movement of the margin of a monolayer into a wound. Magnesium will not substitute for calcium to maintain motility. Strontium will substitute, but is not as effective as calcium for maintaining cell movement. Low concentrations of the divalent cation ionophore A23187 (0.5-1 micron) partially reverse the reduced migration observed at low calcium concentrations. These results are consistent with the hypothesis that movement of non-muscle cells occurs through mechanisms similar to those important in the contraction of muscle.

Tens of terabits-per-second bandwidth will be required for revolutionary chip-multithreading (CMT) architectures. In this presentation, we will review the technical challenges for electrical signaling and discuss how parallel optical interconnects could be valuable in CMT architectures.
Abstract LB-226: The effect of cabozantinib to temozolomide and bevacizumab in patients with heavily pretreated relapsed uterine leiomyosarcoma (2016)

Abstract Background: Although uterine leiomyosarcoma (ULMS) has been treated with adriamycin, dacarbazine, ifosfamide, gemcitabine, docetaxel, et al, the effect is not satisfactory. We have reported the effect of temozolomide (T) combined with bevacizumab (B) in heavily pretreated relapsed ULMS. In this study, we evaluated the effects of addition of cabozantinib (C) to T and B. Methods: From 2009 to 2015, total 18 patients (pts) with heavily pretreated relapsed ULMS were enrolled. They were treated with T (80mg/body/day) and B (2mg/kg; days 1, 8 and 15, q4 weeks). Since 2013, we expected better efficacy, nine pts out of 18 pts were treated by adding C (140mg/body/week) which is a c-MET inhibitor (TB, n = 9, CTB, n = 9). Treatment was continued until disease progression and/or unmanageable toxicities. The response and adverse events were evaluated using the response evaluation criteria in solid tumors (RECIST), and common terminology criteria for adverse events (CTCAE) version 3.0. Results: As shown in Table, three (18%) of 17 pts had complete response (CR), two (12%) had partial response (PR) and eight (47%) had stable disease (SD) for at least three months. The response rate (RR; CR+PR) and clinical benefit rate (CBR; CR+PR+SD&amp;gt;3mo) were 29% and 76%, respectively. The median progression-free survival was 9.6 (3 - 58) months. When compared CTB with TB, CBR was better in CTB (87.5% vs 67%), but the median administration cycles and progression free interval were not improved. Two peritoneal perforation were observed in CTB. Conclusions: Not only TB but also CTB showed remarkable effect in heavily pretreated relapsed ULMS. These results warrant further prospective and randomized studies. nCRPRSDPDRR(%)CBR(%)TB/CTB1732842976TB921333367CTB811512587.5 Citation Format: Sayaka Ikeda, Kazuya Kudoh, Naoki Sasaki, Masashi Takano, Tomoko Goto, Ryoko Kikuchi, Tsunekazu Kita, Masaru Sakamoto, Nobuyuki Susumu, Daisuke Aoki, Hiroko Kouta, Yoshihiro Kikuchi.

Enantiomerically Pure Bithiophene Diphosphine Oxides as Catalysts for Direct Double Aldol Reactions (2013)

The direct aldol reaction between aryl methyl ketones with aromatic aldehydes in the presence of tetrachlorosilane and a catalytic amount of a chiral bithiophene diphosphine oxide was studied; the product of double aldol addition was isolated as diacetate in good diastereoselectivity (up to 95:5) and enantioselectivities up to 91%. The reaction with heteroaromatic aldehydes was also investigated leading to the corresponding 1,3 diols, in some cases with excellent stereoselectivities.
Batch Logical Protocols for Efficient Multi-Party Computation (2012)

It is becoming more and more important to make use of personal or classified information while keeping it confidential. A promising tool for meeting this challenge is secure multi-party computation (MPC). It enables multiple parties, each given a snippet of a secret s, to compute a function f(s) by communicating with each other without revealing s. However, one of the biggest problems with MPC is that it requires a vast amount of communication. Much research has gone into making each protocol (equality testing, interval testing, etc.) more efficient. In this work, we make a set of multiple protocols more efficient by transforming them into their equivalent batch processing form and propose two protocols: “Batch Logical OR” and “Batch Logical AND.” Using proposed protocols recursively, we also propose “Batch Logical OR-AND” and “Batch Logical AND-OR,” and show arbitrary formula consisting of Boolean protocols, OR gates, and AND gates can be batched. Existing logical OR and logical AND protocols consisting of t equality testing invocations have a communication complexity of O(lt), where l is the bit length of the secrets. Our batched versions of these protocols reduce it to O(l+t). For t interval testing invocations, they reduce both communication and round complexity. Thus they can make the queries on a secret shared database more efficient. For example, the use of the proposed protocols reduces the communication complexity for a query consisting of equality testing and interval testing by approximately 70% compared to the use of the corresponding existing protocols. The concept of the proposed protocols is versatile and can be applied to logical formulae consisting of protocols other than equality testing and interval testing, thereby making them more efficient as well.
On the performance of double-gate MOSFET circuit applications (2007)

In this paper, we carry out a quantitative analysis of the performance of Double-Gate (DG) MOSFET circuit applications through various benchmark structures (NAND cell, ring oscillator and voltage controlled oscillator). Simulation results in double-gate fully depleted SOI/CMOS technology of the considered benchmarks under V <sub xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">dd</sub> =1.2 V have shown that design with connected gates outperforms design with independent gate control with regard to speed and die area, while design with independent gate control is more appropriate for managing both dynamic and static power.

This paper presents a 1-bit digital transmitter system with voltage-mode class-D digital power amplifiers (DPA) and an FPGA-based 1-bit modulator for the first time. The DPA employs quadruple cascode configuration with 45 nm SOI CMOS process to increase an operation voltage. The DPA exhibits output swing voltage over 3.2Vpp for 20Gbps RF-pulses under 4V with power consumption of 264mW. The 1-bit digital transmitter system with a digital transmitter IC integrating four DPAs and 4-way transformer-based power combiner convers 2.1-3.8GHz with output power of more than 100mW.
Emax monitoring by aortic pressure waveform analysis (2014)

Emax- the maximal left ventricular elastance- is perhaps the best available scalar index of contractility. However, the conventional method for its measurement involves obtaining multiple ventricular pressure-volume loops at different loading conditions and is thus impractical. We previously proposed a more practical technique for tracking Emax from just a single beat of an aortic pressure waveform based on a lumped parameter model of the left ventricle and arteries. Here, we tested the technique against the conventional Emax measurement method in animals during inotropic interventions. Our results show that the estimated Emax changes corresponded fairly well to the reference changes, with a correlation coefficient of 0.793. With further development and testing, the technique could ultimately permit continuous and less invasive monitoring of Emax.
Mineral Fillers in Intumescent Fire Retardant Formulations ? Criteria for the Choice of a Natural Clay Filler for the Ammonium Polyphosphate/Pentaerythritol/Polypropylene System (1996)

Addition of natural clay materials in intumescent polypropylene-based formulations (additive: ammonium polyphosphate and pentaerythritol) leads either to a decrease or to an increase of their fire retardant performances versus the chemical or the physical characteristics of the clay materials. A study of the factors affecting these performances has been carried out using linear and principal components analysis. This analysis shows that the results of the evaluation tests (LOI and UL 94) are affected in different ways by the adduct of the different clay material and that an increase in the LOI is not necessarily related to an increase in the UL 94 classification. LOI values are improved by the presence of the montmorillonite and of illite clay minerals which may react with acidic phosphate to form active carbonization catelysts, in addition, the results of the LOI test are improved by the presence of quartz and other foreign minerals in the clay materials. This study discusses the part played by the different constitutive minerals in the formation of defects in the polymer chain during the mixing process. It is proposed that the presence of these defects leads to a change in fire retardant performance.
Radiographic Comparison of Diaphyseal Grit Blasted With Smooth Surface Stems by Matched Pair Analysis (2000)

A matched pair comparison of two groups of 42 patients who had a total hip arthroplasty with uncemented fixation of the femoral stem with proximal porous coating and distal grit blasting were compared with a stem of identical design except with diaphyseal smooth surfaces. Radiographic analysis was done to determine differences in fixation and bone remodeling at the 2-year followup, and these results were compared with clinical results. The method used for measuring cortical thickness was semiquantitative, with measurements done at 15 1-cm increments beginning at 3 cm distal to the midlesser trochanter. This study determined whether, with an identical stem design, diaphyseal biologic fixation, rather than mechanical fixation, would provide better fixation without significant stress shielding differences. Seven percent of grit blasted stems had radiolucent lines in Gruen Zones 3 to 5, compared with 79% of smooth stems. The smooth stem was on average one size larger so the stress shielding was not different between matched pairs. There was a distinct pattern of adaptive remodeling that occurred in the femur with both stem surfaces. Bone loss was greatest in the proximal medial and proximal posterior bone and occurred along the entire anterior cortex. Bone thickening occurred in the distal medial and posterior cortices and extended below the tip of the prosthesis.
Determinação colorimétrica de metabissulfito (2010)

O ânion metabissulfito é largamente usado como agente anti-oxidante e preservativo de uma variedade de produtos industrializados. A interação desta espécie com o corante pararosanilina é capaz de promover o rebaixamento da banda de absorção do pigmento na região do visível. Utilizando as melhores condições experimentais, tais como, solução tampão Britton e Robinson, pH 5,0 e corante em 1,0x10-4 mol L-1, foi possível obter uma relação entre concentração de metabissulfito e absorbância, na faixa entre 1,3x10-6 mol L-1 a 3,0x10-5 mol L-1. O limite de detecção foi calculado em 5,0x10-7 mol L-1. A metodologia foi aplicada em amostras reais.
Schottky MSM photodetectors on GaN films grown on sapphire by lateral epitaxial overgrowth (1999)

We report the growth and characterization of Schottky based metal-semiconductor-metal ultraviolet photodetectors fabricated on lateral epitaxially overgrown GaN films. The lateral epitaxial overgrowth of GaN was carried out on basal plane sapphire substrates by low pressure metalorganic chemical vapor deposition and exhibited lateral growth rates more than 5 times as high as vertical growth rates. The spectral responsivity, the dependence on bias voltage, on incident optical power, and the time response of these photodetectors have been characterized. Two detector orientations were investigated: one with the interdigitated finger pattern parallel and the other perpendicular to the underlying SiO<SUB>x</SUB> mask stripes.

High-Speed OTDM and WDM Networks Using Traveling-Wave Electroabsorption Modulators (2007)

We describe the design and performance of a number of elements based on traveling-wave electroabsorption modulators (TW-EAMs) in optical time-division-multiplexing (OTDM) and wavelength-division-multiplexing (WDM) networks. The incorporation of traveling-wave (TW) electrode design into electroabsorption modulators (EAMs) relieves the resistance-capacitance (RC ) bandwidth limitation common to lumped components, enabling higher operation speed without shortening the device. As a result, high-speed operation can be combined with essential modulator characteristics such as modulation efficiency and extinction ratio. While significant modulation bandwidth has been achieved, a lesser known aspect is that the TW electrode also provides an extra dimension for improving and enabling functionalities beyond broadband modulation. This new dimension originates from the distributed effect of the TW design and its interactions with distinctive EAM properties. This paper reviews such developments in recent years with specific applications for optical signal processing in OTDM and WDM networks. The covered functionalities include various optical gating operations for OTDM, regenerative wavelength conversions for WDM, and clock recovery
Smart Engines: Concept and Application (1993)

This article briefly describes the concept of “smart” engine components and discusses various applications of this concept that are currently in the research phase. The interdisciplinary nature of smart engine research is then illustrated through a review of dynamic control of aerodynamic instabili ties in gas turbine compression systems (rotating stall and surge). It has been demonstrated that these instabilities can be stabilized by active feedback control. Basic interdisciplinary questions have evolved based on this research, including identification of unsteady fluid mechanics, choosing suitable signals and wave launchers for implementing feedback, and enabling technologies for real-world control of engine components.
Proceedings of the third international symposium on carbonate fuel cell technology (1997)

This Proceedings volume contains 37 of 41 papers presented at the Third International Symposium on Carbonate Fuel Cell Technology, May 19-21, 1993 in Honolulu, Hawaii. These papers represent research and development efforts in Japan, Europe and the United States. The papers are printed here in the order they were presented in the Symposium, which in general was organized in the order of (1) programmatic overviews, (2) reviews of CFC stack designs and performance tests, (3) reviews of component development issues, and (4) component research and modeling. It is clear from the content of these papers that considerable progress has been made since the last Symposium, particularly in achieving improved performance of large CFC stacks. This technology is now entering the commercialization stage. Papers have been processed separately for inclusion on the data base.
Temperature-dependent diffusing acoustic wave spectroscopy with resonant scatterers (2008)

The influence of a slight temperature change on the correlation of multiply scattered acoustic waves is studied, and experimental results are discussed. The technique presented here, similar to diffuse acoustic wave spectroscopy, is based on the sensitivity of a multiple scattering medium to a slight change. Ultrasonic waves around 3 MHz are transmitted through a sample made of steel rods in water and recorded by an array of transducers at different temperatures. The cross-correlations between highly-scattered signals are computed. The main effect of the temperature change is a simple dilation of the times of arrival, due to a change of the sound velocity in water. But the scatterers also play a role in the progressive decorrelation of waveforms. An analysis resolved in both time and frequency shows that at some particular frequencies, the resonant behavior of the scatterers are responsible for a significantly larger decorrelation. Interestingly, the experimental results allow one to detect the presence of a small resonance that was not detected earlier on the same scatterers with classical measurement of the scattering mean freepath. A simple model is proposed to interpret the experimental results.
Effect of Emulsifying Agents on Inhibition of Enzymatic Browning in Apple Juice by Ascorbyl Palmitate, Laurate and Decanoate (1989)

ABSTRACT The effects of emulsifying agents (EA) on the stability of aqueous dispersions of ascorbyl palmitate (AP), laurate (AL), and decanoate (AD), and on the effectiveness of these compounds as browning inhibitors in apple juice were investigated. The stability of 1.14 mM AP, AL or AD, dispersed in simulated juice, was greatly improved by the addition of hydrophilic EA's such as Tween 60. More lipophilic EA's also were effective in stabilizing AL and AD dispersions. However, the addition of EA's to these browning inhibitors failed to improve their effectiveness in juice and, in the case of Tweens, had a detrimental effect. These results are attributed to the solubilization or activation of bound polyphenol oxidase.
Foci of Endemic Simian Immunodeficiency Virus Infection in Wild-Living Eastern Chimpanzees ( Pan troglodytes schweinfurthii ) (2003)

Simian immunodeficiency virus of chimpanzees (SIVcpz) is the immediate precursor to human immunodeficiency virus type 1 (HIV-1), yet remarkably, the distribution and prevalence of SIVcpz in wild ape populations are unknown. Studies of SIVcpz infection rates in wild chimpanzees are complicated by the species' endangered status and by its geographic location in remote areas of sub-Saharan Africa. We have developed sensitive and specific urine and fecal tests for SIVcpz antibody and virion RNA (vRNA) detection and describe herein the first comprehensive prevalence study of SIVcpz infection in five wild Pan troglodytes schweinfurthii communities in east Africa. In Kibale National Park in Uganda, 31 (of 52) members of the Kanyawara community and 39 (of approximately 145) members of the Ngogo community were studied; none were found to be positive for SIVcpz infection. In Gombe National Park in Tanzania, 15 (of 20) members of the Mitumba community, 51 (of 55) members of the Kasekela community, and at least 10 (of approximately 20) members of the Kalande community were studied. Seven individuals were SIVcpz antibody and/or vRNA positive, and two others had indeterminate antibody results. Based on assay sensitivities and the numbers and types of specimens analyzed, we estimated the prevalence of SIVcpz infection to be 17% in Mitumba (95% confidence interval, 10 to 40%), 5% in Kasekela (95% confidence interval, 4 to 7%), and 30% in Kalande (95% confidence interval, 15 to 60%). For Gombe as a whole, the SIVcpz prevalence was estimated to be 13% (95% confidence interval, 7 to 25%). SIVcpz infection was confirmed in five chimpanzees by PCR amplification of partial pol and gp41/nef sequences which revealed a diverse group of viruses that formed a monophyletic lineage within the SIVcpzPts radiation. Although none of the 70 Kibale chimpanzees tested SIVcpz positive, we estimated the likelihood that a 10% or higher prevalence existed but went undetected because of sampling and assay limitations; this possibility was ruled out with 95% certainty. These results indicate that SIVcpz is unevenly distributed among P. t. schweinfurthii in east Africa, with foci or "hot spots" of SIVcpz endemicity in some communities and rare or absent infection in others. This situation contrasts with that for smaller monkey species, in which infection rates by related SIVs are generally much higher and more uniform among different groups and populations. The basis for the wide variability in SIVcpz infection rates in east African apes and the important question of SIVcpz prevalence in west central African chimpanzees (Pan troglodytes troglodytes) remain to be elucidated.
