Potential energy and electronic transition moment functions for the lowest five triplet states of N2 have been calculated from highly correlated multiconfiguration-reference CI wave functions. From the calculated transition moments and RKR potential energy functions, radiative transition probabilities and lifetimes have been evaluated which are believed to be accurate within 15%. The theoretical lifetime of 36.7 ns of the C 3Πu state is in close agreement with the most recent experimental values. The calculated lifetimes of the B 3Πg state decrease from 13.4 μs for v′=0 to 4.82 μs for v′=12. The values for v′=5 to v′=12 are in good agreement with recent LIF measurements. The lifetimes for v′=0 to v′=4, however, are considerably larger than most previously measured values. The fact that the calculated values are very stable with respect to improvements of the electronic wave functions leads us to conclude that the experimental values are too low. Empirical transition moment functions for the B–A system are apparently too steep, and the moments at short distances much too large. Previous estimates of the lifetimes of the W 3Δu vibrational levels are three times smaller than our calculated values, whereas estimates for the B 3Σ−u state agree reasonably well with the theoretical results.
ADAutomation: An Activity Diagram Based Automated GUI Testing Framework for Smartphone Applications (2014)

Under the increasing complexity and time-to-market pressures, functional validation is becoming a major bottleneck of smartphone applications running on mobile platforms (e.g., Android, iOS). Due to the GUI (Graphical User Interface) intensive nature, the execution of smartphone applications heavily relies on the interactions with users. Manual GUI testing is extremely slow and unacceptably expensive in practice. However, the lack of formal models of user behaviors in the design phase hinders the automation of GUI testing (i.e., test case generation and test evaluation). While thorough test efforts are required to ensure the consistency between user behavior specifications and GUI implementations, few of existing testing approaches can automatically utilize the design phase information to test complex smartphone applications. Based on UML activity diagrams, this paper proposes an automated GUI testing framework called AD Automation, which supports user behavior modeling, GUI test case generation, and post-test analysis and debugging. The experiments using two industrial smartphone applications demonstrate that our approach can not only drastically reduce overall testing time, but also improve the quality of designs.
Studies on Contaminant Biodegradation in Slurry, Wafer, and Compacted Soil Tube Reactors (1996)

A systematic experimental approach is presented to quantitatively evaluate biodegradation rates in intact soil systems. Knowledge of bioremediation rates in intact soil systems is important for evaluating the efficacy of in-situ biodegradation and approaches for enhancing degradation rates. The approach involves three types of soil bioreactors: slurry, wafer, and porous tube. In the soil slurry reactor, biodegradation occurs in the aqueous phase by suspended and soil-immobilized microorganisms. In the soil wafer reactor, diffusivity of contaminant in the soil matrix controls the biodegradation rate. In the porous tube reactor, oxygen limitations occur inside the tube due to diffusional resistances, and oxygen consumption occurs due to biodegradation. Measurement of cumulative oxygen uptake in soil slurry, wafer, and porous tube reactors are used to determine biokinetics and transport parameters. It is shown that biodegradation rates in intact soil systems are slower than in soil slurry reactors. Furthermore, soil tube reactors in conjunction with respirometry can be used to assess bioremediation rates in intact soil systems.

<i>In vitro</i> monocyte adhesion and activation on modified FEP copolymer surfaces (1995)

Abstract The functional group content and the ionic state of functional groups present on a series of surface modified poly(tetrafluoroethylene/hexafluoropropylene) (FEP) copolymers were characterized by electron spectroscopy for chemical analysis (ESCA), contact angle, and attenuated total reflection Fourier transform infrared spectroscopy (ATR‐FTIR). Additionally, after a protein was preadsorbed on these surfaces, in vitro cell (monocyte) adhesion and activation were analyzed. The two proteins in this study were fibrinogen and immunoglobulin‐G (IgG). Four modified FEP surfaces were prepared with increasing concentration of carboxyl groups relative to amide groups; ESCA was used to quantify the functional group content. To characterize the ionic state of the functional groups at physiological pH (7.1), the ATR‐FTIR spectra were collected at various pH levels. Collectively, the contact angle, ESCA, and ATR‐FTIR results suggested that the amide groups were unprotonated and the carboxyl groups were ionized at the physiological pH. The results from the in vitro studies showed that on the fibrinogen preadsorbed surfaces, monocyte adhesion was higher and monocyte activation was lower on the three surfaces that contained carboxyl groups compared to the FEP surface that had only amide groups. Conversely, the results indicated that the surface chemistry had no significant effect on monocyte adhesion or activation on the IgG preadsorbed surfaces. © 1995 John Wiley & Sons, Inc.
Ge Condensation Technologies for Advanced MOSFETs on SGOI and GOI Substrates (2006)

Recent developments in the Ge condensation technique for the fabrication of the SiGe on insulator (SGOI) structures, which are the basic templates for the strained channel MOSFET's, and the further extensions to the SGOI formation on (110) substrates and the Ge on insulator (GOI) formation are reviewed in this paper. The detail analyses of the phenomenon during the initial stage in the Ge condensation process, in which the fragments of the misfit dislocations, that are formed at the SiGe / SOI interface, rise up resulting the generation of the threading dislocations are quite important, and the controlling of the understood phenomenon by the modification of the condensation recipe brings the successful fabrication of the high quality SGOI substrates with low dislocation density.
Version propagation in federated database systems (2002)

Integrated engineering environments, based on federated database technology, are, among others, a means to control the integrity of and dependencies between product data created in many different engineering applications. Most of these applications support the management of versions of a product and its parts, continuing the engineers' tradition of keeping different versions of drawings and documents. Consequently, federations in engineering environments have to provide version management on their global layer as well. The paper discusses the concepts for a flexible and customisable realisation of the federated database management system's version propagation service. This service is responsible for making a new local version "visible" at the global layer of the federation and vice versa. It tries to identify properties like a new version's history and predecessor automatically. We show how these properties can (and sometimes must) be completed or updated if they are incomplete, inapplicable, or even contradictory. We conclude that the customisation overhead is inevitable for any general solution bridging highly heterogeneous versioning models.
Language design for distributed objects (2009)

The fundamental ideas of distributed objects have changed little in the last 20 years. Existing languages are retrofitted with transparent distribution mechanisms based on proxies. Experiments with mobile code demonstrate its power but have little impact on practice. The problems with transparency and mobile code have been well known since at least 1994. But in the absence of any fundamental new ideas, the same problematic approaches are used, for example in the design of Java RMI. In this essay we discuss a new programming construct called Remote Batch Invocation (RBI). A batch is a code block that combines remote and local execution over fine-grained object interfaces, but is executed by partitioning and remote evaluation. Remote Batch Invocation effectively addresses the shortcomings of transparent distribution with a controlled form of mobile code. Our experience leads us to believe that distribution cannot be implemented as a library, but requires specific language support. Viewing distribution as a language design problem represents a revolutionary step in the development of distributed objects.
Realization of Real-Time Fault-Tolerant Quantum Error Correction (2021)

Correcting errors in real time is essential for reliable large-scale quantum computations. Realizing this high-level function requires a system capable of several low-level primitives, including single-qubit and two-qubit operations, midcircuit measurements of subsets of qubits, real-time processing of measurement outcomes, and the ability to condition subsequent gate operations on those measurements. In this work, we use a 10-qubit quantum charge-coupled device trapped-ion quantum computer to encode a single logical qubit using the 7; 1; 3 color code, first proposed by Steane [Phys. Rev. Lett. 77, 793 (1996)]. The logical qubit is initialized into the eigenstates of three mutually unbiased bases using an encoding circuit, and we measure an average logical state preparation and measurement (SPAM) error of 1.72 10 -3 , compared to the average physical SPAM error 2.44 10 -3 of our qubits. We then perform multiple syndrome measurements on the encoded qubit, using a real-time decoder to determine any necessary corrections that are done either as software updates to the Pauli frame or as physically applied gates. Moreover, these procedures are done repeatedly while maintaining coherence, demonstrating a dynamically protected logical qubit memory. Additionally, we demonstrate non-Clifford qubit operations by encoding a Tji L magic state with an error rate below the threshold required for magic state distillation. Finally, we present system-level simulations that allow us to identify key hardware upgrades that may enable the system to reach the pseudothreshold.
Parameterless-Growing-SOM and Its Application to a Voice Instruction Learning System (2010)

An improved self-organizing map (SOM), parameterless-growing-SOM (PL-G-SOM), is proposed in this paper. To overcome problems existed in traditional SOM (Kohonen, 1982), kinds of structure-growing-SOMs or parameter-adjusting-SOMs have been invented and usually separately. Here, we combine the idea of growing SOMs (Bauer and Villmann, 1997; Dittenbach et al. 2000) and a parameterless SOM (Berglund and Sitte, 2006) together to be a novel SOM named PL-G-SOM to realize additional learning, optimal neighborhood preservation, and automatic tuning of parameters. The improved SOM is applied to construct a voice instruction learning system for partner robots adopting a simple reinforcement learning algorithm. User's instructions of voices are classified by the PL-G-SOM at first, then robots choose an expected action according to a stochastic policy. The policy is adjusted by the reward/punishment given by the user of the robot. A feeling map is also designed to express learning degrees of voice instructions. Learning and additional learning experiments used instructions in multiple languages including Japanese, English, Chinese, and Malaysian confirmed the effectiveness of our proposed system.
Mouse sperm-egg plasma membrane interactions: analysis of roles of egg integrins and the mouse sperm homologue of PH-30 (fertilin) β (1995)

The guinea pig sperm protein, PH-30 (also known as fertilin), is postulated to participate in the interaction between the sperm and egg plasma membranes. The beta subunit of guinea pig PH-30 (gpPH-30 beta) contains a domain with homology to disintegrins, snake venom proteins that bind to integrins via an integrin-binding domain containing the tripeptide RGD. This raises the question of whether an egg integrin serves as a receptor for PH-30. Although mouse eggs express integrin subunits, their role in mouse fertilization is unresolved. Therefore, we examined fertilization for two different hallmarks of integrin function, namely, dependence of ligand binding on divalent cations and the ability to inhibit ligand binding with RGD peptides. We demonstrate that sperm binding to zona pellucida-free eggs is supported by Ca2+, Mg2+, or Mn2+. Ca2+ was necessary and sufficient for sperm-egg fusion, with 2.5 mM Ca2+ being the most effective concentration. In addition, fertilization could be partially inhibited with various RGD peptides, which caused a decrease in sperm-egg fusion by 30-58%. This partial inhibition of fusion with RGD peptides prompted the cloning of the mouse homologue of gpPH-30 beta (hereafter referred to as mPH-30 beta) to determine if it possessed the tripeptide RGD or a different amino acid sequence in its disintegrin domain. mPH-30 beta, which is expressed during meiotic and post-meiotic phases of spermatogenesis, shares significant similarities to gpPH-30 beta throughout the length of the molecule, from the signal sequence to the cytoplasmic tail. The full-length deduced amino acid sequence of mPH-30 beta. The disintegrin domain of mPH-30 beta has the tripeptide QDE (instead of RGD) in its cell recognition region. Peptides containing this QDE sequence decrease the binding and fusion of sperm with zona pellucida-free eggs by approximately 70%, suggesting that the disintegrin domain of mPH-30 beta participates in the interaction between sperm and egg membranes.
Thymic Microchimerism Correlates with the Outcome of Tolerance-Inducing Protocols for Solid Organ Transplantation (2001)

This study found that pretransplant infusion of donor peripheral blood leukocytes, either total leukocytes (peripheral blood leukocytes) or peripheral blood mononuclear cells (PBMC), under appropriate immunomodulating conditions was more effective than donor bone marrow (BM) in prolonging the survival of rats that received kidney grafts. A higher percentage of MHCII(+) cells was found in donor PBMC than in BM cells, and depletion of MHCII(+) cells from donor PBMC abolished their tolerogenic potential. By the analysis of microchimerism in rats infused with donor cells and killed at different time points thereafter, the better tolerogenic potential of leukocyte infusion related to a higher capability of these cells to engraft the recipient thymus. PCR analysis on OX6-immunopurified cells revealed the presence of donor MHCII(+) cells in the thymus of these animals. The role of intrathymic microchimerism was reinforced by findings that thymectomy at the time of transplant prevented tolerance induction by donor leukocytes. Donor DNA was found in the thymus of most long-term graft animals that survived, but in none of those that rejected their grafts. The presence of intrathymic microchimerism correlated with graft survival, and microchimerism in other tissues was irrelevant. PCR analysis of DNA from thymic cell subpopulations revealed the presence of donor MHCII(+) cells in the thymus of long-term surviving animals. Thus, in rats, donor leukocyte infusion is better than donor BM for inducing graft tolerance, defined by long-term graft survival, donor-specific T cell hyporesponsiveness, and reduced interferon gamma production. This effect appears to occur through migration of donor MHCII(+) cells in the host thymus.
Effects of 12-week avocado consumption on cognitive function among adults with overweight and obesity (2019)

Daily avocado intake over 12 weeks, after controlling for covariates, improved attentional inhibition and increased serum lutein concentrations among adults with overweight and obesity. However, the cognitive benefits were independent of changes in lutein concentrations. Additional work is necessary to determine non-carotenoid, or carotenoid interactive, mechanisms by which avocados may influence cognitive function.
Optical manipulation of metal-silica hybrid nanoparticles (2004)

Metallic nanoparticles are known to experience enhanced optical trap strengths compared to dielectric particles due to the increased optical volume, or polarizability. In our experience, larger metallic particles (~micron) are not easily trapped because momentum effects due to reflection become significant. Hybrid particles comprised of both metal and dielectric materials can circumvent this limitation while still utilizing a larger polarizability. Heterogeneous nanosystems were fabricated by embedding/coating silica nanoparticles with gold or silver in varying amounts and distributions. These compound particles were manipulated via optical tweezers, and their trapping characteristics quantitatively and qualitatively compared to homogeneous particles of comparable size. The parameters explored include the dependence of the trapping force on the percentage of loading of gold, the size of the embedded colloids, and the distribution of metal within the surrounding matrix or on its surface.
A necessary and sufficient condition for the BIBO stability of general-order bode-type variable-amplitude wave-digital equalizers (2003)

Recently, the authors developed a new synthesis technique for the design of higher-order Bode-type variable-amplitude (VA) wave-digital (WD) equalizers. The salient feature of the resulting VA WD equalizers is that they permit the continuous variation of the WD equalizer transfer function from a shaping transfer function to its inverse by changing the value of a single variable digital multiplier only. The proposed design technique was based on the WD realization of the corresponding positive-real analog prototype shaping impedance function, and on the realization of the equalizer transfer function as the reflectance of the shaping impedance function with respect to the constituent variable digital multiplier. This paper is concerned with an investigation of the bounded-input bounded-output (BIBO) stability of general-order VA WD equalizers. It is shown that the resulting conditions are both necessary and sufficient for the BIBO stability of the VA WD equalizers for the entire range of values for the variable digital multiplier. These conditions can be checked in a straightforward fashion in terms of the characteristics of the shaping transfer function alone. An application example is given to illustrate the main results.

Effects of pyridoxine of male fertility. (1995)

Pyridoxine (PN) was intraperitoneally given at 250 and 500 mg/kg to male rats for 2, 4, or 6 weeks, and its effects on male fertility evaluated in terms of the optimal treatment period and detection parameters. Animals of all PN groups showed depression of body weight gains from week I of treatment onwards, significant at all but the 250 mg/kg 2 week administration I week time point. After 2 weeks treatment, the testes demonstrated only very slight histopathological changes. The 4- and 6-week treatments caused decreased spermatozoal motility and some histopathological changes in the testes including degeneration of germinal epithelial cells with both doses and also decreases in the fertility index and mean velocity of sperm, reduction in the testes and epididymides weights, and changes in testicular proteins. In the animals undergoing a 4-week recovery period following 4 or 6 weeks exposure, changes disappeared with the 250 mg/kg dose, but still remained with 500 mg/kg. From these findings, it is concluded that a treatment period of 4 weeks is sufficient for evaluation of drug effects on male fertility and that histopathology can detect the slightest toxic effects on the testis.
Effects of bis(7)-tacrine, a novel anti-Alzheimerʼs agent, on rat brain AChE (1999)

The anticholinesterase effects of bis(7)-tacrine were compared with tacrine in vitro and in vivo. Based on IC50 ratios, the dimeric analog bis(7)-tacrine was, in a reversible manner, up to 150-fold more potent and 250-fold more selective than tacrine for acetylcholinesterase (AChE) over butyrylcholinesterase (BChE). Following a single oral administration, both bis(7)-tacrine and tacrine produced dose-dependent inhibitions of AChE in rat brain, but bis(7)-tacrine exhibited higher efficacy and AChE/BChE selectivity than tacrine. The anti-AChE efficacy of bis(7)-tacrine was quite similar following an oral or i.p. administration, but tacrine showed much lower efficacy when administered orally than when given i.p. These findings suggest bis(7)-tacrine, a highly potent and selective inhibitor of AChE, can probably be used as an improved drug in the palliative treatment of AD.
