Formation of Nanoporous Features, Flat Surfaces, or Crystallographically Oriented Etched Profiles by the Si Chemical Dry Etching Using the Reaction of F<sub>2</sub> + NO → F + FNO at an Elevated Temperature (2013)

Chemical dry etching of Si was performed using the reaction of F2 + NO → F + FNO at an elevated temperature. The etched profile, surface morphology, and surface chemical bonding structures, measured by a scanning electron microscope, X-ray photoelectron spectroscopy (XPS), and a Fourier transform infrared spectrometer (FT-IR), were significantly changed when the substrate was heated at 27 and 300 °C. Differences in total energies of Si before and after the chemical reaction with gas molecules in the etching apparatus were theoretically calculated by the density functional theory (DFT) using CAM-B3LYP/6-311G+(d,p) in Gaussian 09. The possible change in chemical bonding structures during and after the Si etching was considered by correlating the measured XPS and FT-IR spectra and the DFT calculation results. When the Si sample was heated at 27∼60 °C, the nanoporous features were observed since molecules present in the gas phase remained in the condensed layer near the Si surface and they reacted with the Si surface at different rates. The chemisorbed F2, F, and FNO promoted Si etching by cleaving different bonds to form dangling bonds, whereas NO and OH, produced from the reaction between H2O and F, inhibited the etching by encapsulating dangling bonds. The etch rate was significantly reduced, and the evolution of the flat surface was observed at 60∼230 °C due to the reduction of chemisorbed F2, F, and FNO on the Si surface. When the Si sample was heated at above 230 °C, the etch rate increased with the temperature due to the amplification of the reaction rate constants of F2, F, and FNO with the Si surface. Unique orientation-dependent etching was observed at these temperatures due to the termination of dangling bonds by F without cleaving the Si–Si lattice bonds. The contribution of NO and OH at above 230 °C was ignored since they desorbed from the Si surface.
Stretch-induced hypertrophy of isolated adult rabbit cardiomyocytes (2010)

Both mechanical and humoral triggers have been put forward to explain the hypertrophic response of the challenged cardiomyocyte. The aim of the present study was to investigate whether cyclic equibiaxial stretch is a direct stimulus for isolated adult rabbit cardiomyocytes to develop hypertrophy and to explore the potential involvement of the autocrine/paracrine factors ANG II, transforming growth factor (TGF)-beta(1), and IGF-I in this process. Isolated cardiomyocytes were exposed to 10% cyclic equibiaxial stretch (1 Hz) for up to 48 h or treated with ANG II (100 nM), TGF-beta(1) (5 ng/ml), IGF-I (100 ng/ml), ANG II type 1 (AT(1)) receptor blockers, or conditioned medium of stretched fibroblasts. Cyclic stretch significantly increased cell surface area (+3.1%), protein synthesis (+21%), and brain natriuretic peptide (BNP) mRNA expression (6-fold) in cardiomyocytes. TGF-beta(1) expression increased (+42%) transiently at 4 h, whereas cardiomyocyte IGF-I expression was not detectable under all experimental conditions. The AT(1) receptor blockers candesartan and irbesartan (100 nM) did not prevent the stretch-induced hypertrophic response. Direct exposure to ANG II, TGF-beta(1), or IGF-I did not enhance cardiomyocyte BNP expression. In cardiac fibroblasts, stretch elicited a significant approximately twofold increase in TGF-beta(1) and IGF-I expression. Conditioned medium of stretched fibroblasts increased BNP expression in cardiomyocytes ( approximately 2-fold, P = 0.07). This study clearly indicates that cyclic stretch is a strong, direct trigger to induce hypertrophy in fully differentiated rabbit cardiomyocytes. The present findings do not support the notion that stretch-mediated hypertrophy of adult rabbit cardiomyocytes involves autocrine/paracrine actions of ANG II, TGF-beta(1), or IGF-I.

Performance of a novel carrier frequency offset estimation algorithm for OFDM-based WLANs (2006)

This paper presents a novel carrier frequency offset estimation (CFO) algorithm for orthogonal frequency division multiplexing (OFDM)-based Wireless Local Area Networks (WLANs). Compared with previous approaches, this paper extends the whole frequency offset acquisition range by embedding a synthetic algorithm according to the preamble structure of WLANs symbols. The numerical results presented support the effectiveness of this algorithm by which the estimation error of the whole carrier frequency offset in the WLANs is effectively decreased.
Sensitivity and Stability Analysis of Mu-Synthesis AMB Flexible Rotor (2010)

The paper presents the sensitivity and stability margin analyses of the flexible rotor supported by active magnetic bearings (AMBs) with the robust optimal vibrations control. The modal representation of the rotor finite element model (FEM) is investigated. Then, the open-loop system of the AMBs flexible rotor is established and critical speed analysis due to variation of bearing stiffness is performed. For the open-loop setup, the non-collocation effect of displacement sensors and magnetic actuators due to control stability problem is considered. The frequency mode analysis of the collocation and non-collocation system is presented. Next, the -synthesis control of 4-DOF AMBs rotor is investigated. The design process of -controllers, which cover uncertainty design and performance shape by chosen weighting function is shortly described. Then, the sensitivity function is calculated and used to evaluate the AMBs rotor stability margin for the -control and the PID control. The performance of the -controller are verified in experimental tests.

Towards Constructive Text, Diagram, and Layout Generation for Information Presentation (2001)

Combining elements appropriately within a coherent page layout is a well-recognized and crucial aspect of sophisticated information presentation. The precise function and nature of layout has not, however, been sufficiently addressed within computational approaches; attention is often restricted to relatively local issues of typography and text-formatting, leaving broader issues of layout unaddressed. In this paper we focus on the selection and function of layout in pages that appropriately combine textual and graphical representation styles to yield coherent presentation designs. We demonstrate that layout offers a rich resource for achieving presentational coherence, alongside more traditional resources such as text-formatting and the text-internal marking of discourse connections. We also introduce an integrated approach to layout, text, and diagram generation. Our approach is developed on the basis of a preliminary empirical investigation of professionally produced layouts, followed by implementation within a prototype information system in the area of art history.

[Amyotrophic lateral sclerosis: an autoimmune disease?]. (1991)

Amyotrophic lateral sclerosis is characterized by degeneration of the motor neurones in the central nervous system and, as a rule, the condition results in rapid incapacity and death. The etiology is unknown but experimental results from recent years suggest that immunological mechanisms are of pathophysiological significance. Gangliosides constitute an important membrane component in nerve tissue and the majority of patients probably have high titres of circulation polyclonal IgM-antibodies to these compounds, particularly gangliosides GM1 and GD1a. The antibody titre appears to be correlated with the clinical condition and selective immune suppression (e.g. with cyclophosphamide) may possibly be of therapeutic value.

11-(1H-Pyrrol-1-yl)-11H-indeno[1,2-b]quinoxaline and 3-(1H-pyrrol-1-yl)indolin-2-one derivatives have been synthesized in good yields in a novel, one-pot, and efficient process by condensation of 11H-indeno[1,2-b]quinoxalin-11-one or isatin derivatives with 4-hydroxyproline on solid-support montmorillonite K10 under microwave irradiation.
Active infrared sensors for mobile robots (1994)

Sensors based on the ultrasonic, pulse-echo technique for measuring range have been the mainstay for robotic collision avoidance systems. Although these sensors have been successfully applied to both indoor and outdoor mobile robotic applications, certain disadvantages of these systems prompted our investigation of inexpensive sensors that use light to determine the range or presence of targets. A number of commercially available, light-based sensors are analyzed for application in a mobile robotic space application. The objective of the analysis is to develop a cost-effective, light-based ranging sensor for a collision avoidance system for an experimental Mars Rover. This paper presents some results from our investigation.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">></ETX>
Loopshaped wavefront control using open-loop reconstructors (2006)

Adaptive optics wavefront controllers are tractably synthesized using loopshaping and internal model control principles. Modal responses at low and high temporal frequencies can thus be specified distinctly using pairs of open-loop reconstructors. Theoretical examples and parametric simulations illustrate the stability, robustness, and flexibility of the method, which incorporates several existing techniques.
Genetic Algorithm Based Scheduling Method for Efficiency and Reliability in Mobile Grid (2009)

A mobile grid is emerging as a new opportunity to integrate and utilize the exploding population of mobile resources. However, the mobile grid is not as stable as the traditional fixed grid, and the scheduling scheme plays a crucial role for the efficient job execution. In this paper, we take into account the characteristics of mobile devices such as inferior reliability and limited capacity in scheduling. With the replication scheme adopted to enhance reliability, we propose a novel scheduling scheme for the efficient execution of replicated jobs. Our proposed method is based on genetic algorithm. It strives to minimize the completion time of grid applications and reduce the replication overhead. Our method provides the efficient utilization of mobile grid resources by avoiding executions of useless replica. Experiment results show that our method outperforms the other conventional methods in terms of completion time and wasted resources.

THE TWO-SIGNAL MODEL OF T-CELL ACTIVATION AFTER 30 YEARS (2002)

The two-signal model of T-cell activation is still valid after 30 years. The recent understanding of the first signal intricacy and its tight relationship with the second signal have thrown decisive light on T-cell activation processes and the complex molecular events that occur on the surface and within the T cell. Furthermore, the recognition of numerous accessory pathways that, in addition to the CD28 and CD40 pathways, operate to manage antigen-presenting cell T cell cooperation in view of lymphocyte activation, disclose the exquisite and numerous regulatory events that compose the second signal.
Diffuse Traumatic Axonal Injury in the Optic Nerve Does Not Elicit Retinal Ganglion Cell Loss (2013)

Much of the morbidity after traumatic brain injury (TBI) is associated with traumatic axonal injury (TAI). Although most TAI studies focus on corpus callosum white matter, the visual system has received increased interest. To assess visual system TAI, we developed a mouse model of optic nerve TAI. It is unknown, however, whether this TAI causes retinal ganglion cell (RGC) death. To address this issue, YFP (yellow fluorescent protein)-16 transgenic mice were subjected to mild TBI and followed from 2 to 28 days. Neither TUNEL (terminal deoxynucleotidyl transferase dUTP nick end labeling)-positive or cleaved caspase-3-immunoreactive RGCs were observed from 2 to 28 days after TBI. Quantification of immunoreactivity of Brn3a, an RGC marker, demonstrated no RGC loss; parallel electron microscopic analysis confirmed RGC viability. Persistent RGC survival was also consistent with the finding of reorganization in the proximal axonal segments after TAI, wherein microglia/macrophages remained inactive. In contrast, activated microglia/macrophages closely enveloped the distal disconnected, degenerating axonal segments at 7 to 28 days after injury, thereby confirming that this model consistently evoked TAI followed by disconnection. Collectively, these data provide novel insight into the evolving pathobiology associated with TAI that will form a foundation for future studies exploring TAI therapy and its downstream consequences.
Enhancing catalytic activity and stability for CO<sub>2</sub> methanation on Ni–Ru/γ-Al<sub>2</sub>O<sub>3</sub>via modulating impregnation sequence and controlling surface active species (2014)

Co-impregnation and sequential impregnation were used to prepare a series of Ni–Ru/γ-Al<sub>2</sub>O<sub>3</sub> catalysts for CO<sub>2</sub> methanation. By comparing the structure, surface species and catalytic performances, we uncovered the surface species segregation of Ru in Ni–Ru catalysts, and its effect on catalytic properties.
Mobile monitoring for distributed infrastructures (2006)

Efficient maintenance of distributed infrastructures requires accurate and up-to-date information to ensure reliable service. Existing monitoring techniques commonly rely on either data collected at scattered points or on costly manual inspection of suspect components by service personnel. Implementation of mobile robots for continuous autonomous monitoring of these infrastructures can provide a cost-effective means of gaining accurate information for maintenance planning. This paper offers a discussion on key system-level issues that must be addressed in any mobile monitoring project. These issues include: (a) economic analysis of incorporating mobile robotics into existing maintenance strategies, (b) the ability of the autonomous robot to negotiate diverse and unstructured environment, and (c) the feasibility of integrating needed sensors into a robotic platform. The example application examined in this paper is an autonomous robotic platform that monitors underground power cables for incipient failures.

Cohort Study of the Success of Controlled Weight Loss Programs for Obese Dogs (2015)

Just over half of all obese dogs on a controlled weight loss program reach their target weight. Future studies should better clarify reasons for success in individual cases, and also the role of factors such as activity and behavioral modification.
2-Carboxytetrahydroquinolines. Conformational and stereochemical requirements for antagonism of the glycine site on the N-methyl-D-aspartate (NMDA) receptor (1992)

2-Carboxy-1,2,3,4-tetrahydroquinoline derivatives, derived from kynurenic acid, have been synthesized and evaluated for in vitro antagonist activity at the glycine site on the NMDA receptor. 2,3-Dihydrokynurenic acids show reduced potency relative to the parent lead compounds (Table I) possibly as a result of conformational effects. Removal of the 4-oxo group results in further reduced potency, but introduction of a cis-carboxymethyl group to the 4-position restores antagonist activity (Tables III and IV). Replacement of the keto group of 5,7-dichloro-2,3-dihydrokynurenic acid with other alternative H-bonding groups, for example cis- and trans-benzyloxycarbonyl and cis- and trans-carboxamido (Table V), gives comparable activity, but there is negligible stereoselectivity. A significant increase in potency and stereoselectivity is seen within the 4-acetate series (Table VI). The trans-4-acetic acid is significantly more potent than the corresponding lead kynurenic acid and has 100-fold greater affinity than the cis isomer. The results are consistent with a requirement in binding for a pseudoequatorially placed 2-carboxylate and clearly demonstrate the importance for binding of a correctly positioned hydrogen-bond-accepting group at the 4-position. The high-affinity binding of an anionic group in the 4-substituent binding pocket suggests that the glycine site and the neurotransmitter recognition (NMDA) site may have some features in common.
Metabolism of Imidacloprid in Houseflies (2004)

Metabolism of imidacloprid in the housefly Musca domestica was investigated. After the injection of 14C-labeled imidacloprid, radioactivity decreased to approximately 20% of the initial level within 24 hr. Most of the 14C in the excreta as well as that in the insect body was accounted for by an olefin derivative of imidacloprid. The pre-application of piperonyl butoxide or propargyl propyl phenylphosphonate as a synergist suppressed the degradation of imidacloprid and delayed the excretion of insecticidal components from houseflies. These results suggested that the insecticidal activity of imidacloprid was affected by oxidative metabolic processes.

A Novel SeND Based Source Address Validation Mechanism (SAVM-SeND) (2009)

SAVM-SeND, a solution to provide source address validation using the SeND protocol, is proposed in this paper. It assumes all the hosts are configured with SeND protocol in IPv6 networks and aims to provide a mechanism for the control of the source addresses spoofing in all of the address assigning circumstances. Besides, it supports each host with multiple interfaces, each interface with multiple MAC addresses, port mobility, and can achieve a host level granularity filtering in the access network. In the end, the evaluation is discussed.
Examining the robustness of sensor-based statistical models of human interruptibility (2004)

Current systems often create socially awkward interruptions or unduly demand attention because they have no way of knowing if a person is busy and should not be interrupted. Previous work has examined the feasibility of using sensors and statistical models to estimate human interruptibility in an office environment, but left open some questions about the robustness of such an approach. This paper examines several dimensions of robustness in sensor-based statistical models of human interruptibility. We show that real sensors can be constructed with sufficient accuracy to drive the predictive models. We also create statistical models for a much broader group of people than was studied in prior work. Finally, we examine the effects of training data quantity on the accuracy of these models and consider tradeoffs associated with different combinations of sensors. As a whole, our analyses demonstrate that sensor-based statistical models of human interruptibility can provide robust estimates for a variety of office workers in a range of circumstances, and can do so with accuracy as good as or better than people. Integrating these models into systems could support a variety of advances in human computer interaction and computer-mediated communication.
