Surface-Enhanced Raman Scattering of Ultrathin Cadmium Chalcogenide Films on Gold Formed by Electrochemical Atomic-Layer Epitaxy:  Thickness-Dependent Phonon Characteristics (1999)

The utility of surface-enhanced Raman scattering (SERS) for characterizing phonon and related interfacial vibrations within ultrathin semiconductor layers on gold substrates is demonstrated, specifically for cadmium chalcogenide (CdSe, CdS) films formed by electrochemical atomic layer epitaxy. The occurrence of quantum-confinement effects for CdSe films less than ca. 10 monolayers thick is clearly evident from the observed ca. 12 cm-1 phonon redshifts and bandshape changes. Milder phonon redshifts are seen for the ultrathin CdS films, suggesting the presence of offsetting blueshifts from lattice compression. The observed sensitivity of the phonon spectra to the order of initial Cd/Se or Cd/S monolayer electrodeposition, along with the retention of Au−Se and Au−S vibrational bands upon layer growth, signal the importance of the initial chemisorbate to the epitaxial film structure and vibronic properties.
Automatic defect classification of printed wiring board solder joints (1990)

An automatic windowing algorithm is developed for use in automatic printed wiring board solder joint inspection. The method uses Hough curve detection to locate the solder joint within the image. Eleven good features selected by C.-C. Lee (1987) for use in the solder joint inspection task are studied in detail for purposes of optimizing the inspection process. This is done with the aid of a minimum distance classification algorithm that allows for classification of the solder joint based on user selected features. Automatic windowing, feature selection, and classification algorithms are compiled into a complete solder joint inspection system.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">></ETX>
Effect of Clothing, Sex, and Sex Role Stereotypes on Behavioral Expectations of a Preschool Child (1993)

An experimental design was used to investigate the effect of sex-typed clothing, sex of child, and sex-role stereotype of subject on impressions of a preschool child's competencies and likelihood of engaging in sex-typed behaviors. Sex type of clothing and sex of child were manipulated using four black-and white photographs. Subjects were 100 females enrolled in an introductory early childhood education course. Data were analyzed using analyses of variance and the Neuman-Keul's test. The preschool girl was rated as more socially competent than the preschool boy. None of the independent variables influenced ratings of nonsocial competencies. For impressions of likelihood of engaging in sex-typed behaviors, subjects indicated that a female child was more likely to engage in feminine sex-typed activities than a male child and that a male child was more likely to engage in masculine sex-typed activities than a female child.

Abstract This paper reports the synthesis and the insecticidal activities of some N ‐benzoyl‐ N' ‐arylureas 4‐arylsubstituted with alkylated or halogenated aroyl moieties. The compounds, tested against some representative insect species, displayed very high activity against Aedes aegypti , especially the halosubstituted derivatives. None of the newly synthesized compounds showed genotoxic activity in the Bacillus subtilis rec ‐assay and in the Salmonella ‐microsome test.
Kondo-like zero-bias anomaly in electronic transport through an ultrasmall Si quantum dot (1999)

We have studied charge transport through an ultrasmall Si single electron transistor. We find that at low temperatures, the Coulomb blockade is partially lifted at certain gate voltages. Furthermore, we observed an enhancement of the differential conductance at zero bias. The magnetic field dependence of this zero-bias anomaly is different from that of the Kondo peaks reported in GaAs quantum dots: we observed no splitting of the zero-bias peak with magnetic field.
Natural Stilbenoids Have Anti-Inflammatory Properties <i>in Vivo</i> and Down-Regulate the Production of Inflammatory Mediators NO, IL6, and MCP1 Possibly in a PI3K/Akt-Dependent Manner (2018)

Stilbenoids are a group of polyphenolic compounds found in plants, trees, berries, and nuts. Stilbenoids have been shown to serve an antimicrobial and antifungal function in plants. There is also evidence that as a part of the human diet, stilbenoids play an important role as antioxidants and may have anti-inflammatory effects. The PI3K/Akt pathway is a well-characterized signaling pathway controlling cellular functions involved in growth and cell cycle and in metabolism. There is also increasing evidence to show the involvement of this pathway in the regulation of inflammatory responses. In the present study, an attempt was made to investigate the anti-inflammatory properties of the naturally occurring stilbenoids pinosylvin (1), monomethylpinosylvin (2), resveratrol (3), pterostilbene (4), piceatannol (5), and rhapontigenin (6). Glycosylated derivatives of piceatannol and rhapontigenin, namely, astringin (7) and rhaponticin (8), respectively, were also investigated. In addition to the natural stilbenoids, pinosylvin derivatives (9-13) were synthesized and subjected to the testing of their effects on the PI3K/Akt pathway in inflammatory conditions. The investigated natural stilbenoids (except the glycosylated derivatives) were found to down-regulate Akt phosphorylation, which is a well-acknowledged marker for PI3K activity. It was also found that all of the studied natural stilbenoids had anti-inflammatory effects in vitro. The three most potent stilbenoids, piceatannol, pinosylvin, and pterostilbene, were selected for in vivo testing and were found to suppress inflammatory edema and to down-regulate the production of inflammatory mediators IL6 and MCP1 in carrageenan-induced paw inflammation in mice. When compared to the commercial PI3K inhibitor LY294002, the anti-inflammatory effects appeared to be quite similar. The results reveal hitherto unknown anti-inflammatory effects of natural stilbenoids and suggest that those effects may be mediated via inhibition of the PI3K/Akt pathway.

4.7 GB Phase Change Optical Disc with In-Groove Recording (1999)

We developed a rewritable optical disc with 4.7 GB/side capacity as an extension of the digital versatile disc recordable (DVD-R) system. The disc is readily playable on a read-only DVD player or a DVD-ROM drive with a small firmware modification. As far as the fundamental characteristics of the disc which adopts an in-groove recording are concerned, the reflectivity is 18% or more, modulated amplitude is 60% or greater, and jitter is 8% or less. As we had sufficient differential phase detection (DPD) tracking error signals from the recorded disc, we think the DPD tracking method is practical. These results cleared the single-layer DVD-ROM specifications except for the reflectivity. The measured reflectivity satisfies the specifications of the dual-layer DVD-ROM disc. Furthermore we confirmed that the recorded disc was playable on a blue laser playback system.

Computing and Minimizing Cache Vulnerability to Transient Errors (2009)

Using a cache vulnerability factor to measure the susceptibility of cache memories to transient errors at the architecture level can help designers make appropriate cost and reliability trade-offs at early design cycles. Two early write-back strategies can also improve the reliability of write-back data caches without compromising performance.

Identification of the bile salt binding site on ipad from <i>Shigella flexneri</i> and the influence of ligand binding on IpaD structure (2011)

Type III secretion (TTS) is an essential virulence factor for Shigella flexneri, the causative agent of shigellosis. The Shigella TTS apparatus (TTSA) is an elegant nanomachine that is composed of a basal body, an external needle to deliver effectors into human cells, and a needle tip complex that controls secretion activation. IpaD is at the tip of the nascent TTSA needle where it controls the first step of TTS activation. The bile salt deoxycholate (DOC) binds to IpaD to induce recruitment of the translocator protein IpaB into the maturing tip complex. We recently used spectroscopic analyses to show that IpaD undergoes a structural rearrangement that accompanies binding to DOC. Here, we report a crystal structure of IpaD with DOC bound and test the importance of the residues that make up the DOC binding pocket on IpaD function. IpaD binds DOC at the interface between helices α3 and α7, with concomitant movement in the orientation of helix α7 relative to its position in unbound IpaD. When the IpaD residues involved in DOC binding are mutated, some are found to lead to altered invasion and secretion phenotypes. These findings suggest that adoption of a DOC bound structural state for IpaD primes the Shigella TTSA for contact with host cells. The data presented here and in the studies leading up to this work provide the foundation for developing a model of the first step in Shigella TTS activation.
Investigation of pilot-aided phase noise compensation in CO-OFDM system (2010)

Since conventional CO-OFDM transmission systems are very sensitive to laser phase noise, we introduce a scheme called pilot-aided phase noise compensation, and verify its capacity to compensate phase noise by simulation. Furthermore, how to choose key parameters of this scheme is investigated in order to direct system design.

The organization and consequences of eicosanoid signaling (2003)

As described in the introduction to this Perspective series (1), signaling by arachidonic acid represents a paradigm for the use of oxygen in the transmission of information. At the same time, arachidonic acid signaling can also contribute to the propagation of cellular damage. This duality is typified by a signaling cascade that (a) prevents the activation of 5-lipoxygenase (5-LO) in resting cells and (b) results in the formation and release of leukotrienes (LTs), which requires the sequential activation and interaction of at least eight different proteins. In fact, all lipoxygenases require membrane translocation to exert activity. In the case of the formation of COX products, particularly prostaglandin E 2 (PGE 2 ) and PGD 2 , humans have evolved two sets of biosynthetic enzymes that differ not only in their cell-and tissue-specific localization, but also in their subcellular localization and requirement for reduced glutathione, a cellular defense against oxidative damage. This review will focus on three aspects of arachidonic acid biology. First, the compartmentalization and organization of eicosanoid synthesis, specifically LTs and PGs, will be discussed. This will illustrate the elaborate mechanisms that keep unwanted lipoxygenation at arm's length and also show that the enzymes such as glutathione-Stransferases, epoxide hydrolases, and carrier proteins that are commonly thought of as biosynthetic also belong to families that are generally considered to play a role in detoxification. Second, the potential cellular oxidative damage that is produced as a by-product of the use of oxygen and lipid substrates is examined. Finally, mechanisms that are used to amplify signaling diversity from a core of LTs and PGs are discussed.
Determination of serum cholesterol by a modification of the isotope dilution mass spectrometric definitive method (1989)

An isotope dilution mass spectrometric (ID/MS) method for cholesterol is described that uses capillary gas chromatography with cholesterol-13C3 as the labeled internal standard. Labeled and unlabeled cholesterol are converted to the trimethylsilyl ether. Combined capillary column gas chromatography and electron impact mass spectrometry are used to obtain the abundance ratio of the unlabeled and labeled [M+.] ions from the derivative. Quantitation is achieved by measurement of each sample between measurements of two standards whose unlabeled/labeled ratios bracket that of the sample. Seven pools were analyzed by this method: standard reference material (SRM) 1951, which consists of three frozen serum pools with low, medium, and high levels of cholesterol; SRM 1952, which consists of three freeze-dried serum pools with low, medium, and high levels of cholesterol; and SRM 909, a freeze-dried serum pool. The method is a modification of our original definitive method for cholesterol. The modified method uses much better chromatographic separations to assure specificity and a new method of implementing selected ion monitoring on a magnetic mass spectrometer to obtain high-precision measurements of ion intensity ratios on narrow gas chromatographic peaks. The modified method has a coefficient of variation (CV) of 0.22%, which is an improvement over the original method's CV of 0.36%. The measurements were found to be free of interference. The high precision and absence of bias qualify this method as a candidate definitive method.
Counts of Influenza Virus Particles (1954)

SUMMARY: Particle counts of influenza virus preparations were made by two independent techniques; there was good agreement in the counts found by the two methods. Counts made on four strains of influenza virus and one strain of ‘incomplete’ virus showed that at the agglutination end-point there was about one virus particle per red cell. Parallel infectivity measurements of these strains made under optimal conditions showed that about ten virus particles corresponded to one ID 50.
Optimal Selection of Image Segmentation Algorithms Based on Performance Prediction (2008)

Using different algorithms to segment different images is a quite straightforward strategy for automated image segmentation. But the difficulty of the optimal algorithm selection has prevented it from being used for many years. In this paper, a framework of algorithm selection system is proposed to achieve automated image segmentation. Off-line learning scheme is adopted to make use of interactive segmentation evaluation. During training, both the performance ranks of candidate algorithms on every image and image features are used to train a predictor. Then, the performance ranks of all candidates will be predicted according to image features. Finally, the algorithm with the highest rank will be regarded as optimal and applied to the image. A simulation system is constructed to select optimal segmentation algorithm from four candidates for synthetic images. In this system, histogram is used as image feature, the number of misclassified pixels and computation expenses are used to facilitate interactive segmentation evaluation, and Principle Components Analysis (PCA) and Support Vector Machine (SVM) are used to construct the predictor. The system is tested on 9000 images by comparing with the manual selection. The best algorithms are selected for 84.90% of cases. If the second best algorithm is also regarded as acceptable, more than 97.5% of images can be properly segmented. The satisfied results demonstrate that this study has provided a promising approach to automated image segmentation .
Improved materials meeting the demands for EUV substrates (2003)

The enhanced demands for substrate materials for next-generation optics and masks have initiated detailed investigations on Zerodur as a proposed EUVL substrate material with focus on thermal expansion behavior and surface roughness. As a result of specifically adjusted process parameters, the coefficient of thermal expansion (CTE) was tailored to be a minimum at 22.5°C. Laboratory samples of Zerodur exhibit a CTE < 5 ppb/K corresponding to the lowest expasnion class of the SEMI standard P37 (19 to 25°C) for EUV mask blanks. By further variation of process parameters, the position of zero crossing, e.g. at 30°C, can be varied, revealing an attractive attribute feature of Zerodur. A new dilatometer type was mounted in 2002 with first operatinoal results revealing an improved reproducibility of ~1ppb/K in the temperature range of 0 to 50°C. A series of CTE measurements with a small block of Zerodur provides information on CTE homogeneity on a cm-scale: No CTE variation was observed within the error of measurements for a block exhibiting ± 3.5*10<sup>-6</sup> vairtion in refractinve index. CTE variation can cause surface deformations during changing temperature conditions. A first setup of Fizeau-Interferometer with a current resolution of 0.3 nm rms was used to record surface deformation of Zerodur due to elevated temperature was determined to be lower than the current resolution. Both methods to analyze the CTE homogeneity of Zerodur lead to the result of CTE variation below 1 ppb/K, still identifying today's need to improve metrology further. Final finishing of EUV substrates may increase roughness of super-polished surfaces significantly. Using appropriate processes a to surface roughness < 0.25 nm rms under production conditions can be achieved after final finishing of Zerodur. As an improved Zerodur-type material, recent achievements of material development demonstrate the optimization of glass-ceramic composition to nearly meeting the specification of surface roughness after a standard finishing process. These results are regarded as a promising milestone to develop an optimized glass-ceramic material providnig adjusted thermal expansion behavior and surface processability according to the specific demands of EUV technology.
Reduction of Some Alkylisoxazoles with Lithium Aluminum Hydride (1975)

Lithium aluminum hydride reduction of alkyl substituted isoxazoles gave a variety of products. The major constituent was identified (i.r., n.m.r., m.s.) as hydroxyethylaziridine. Specifically, reduction of 3,4,5-trimethylisoxazole gave as the major product 2,3-dimethyl-3-β-hydroxyethylaziridine. Two of the more prominent minor products were identified as 2,3-dimethyl-3-ethylaziridine and 4-amino-3-methyl-2-pentanol. The corresponding products were identified when 3,5-dimethylisoxazole was reduced with LAH.
Enabling single sign-on authentication for web repositories using domain directory services (2008)

The Nanyang Technological University - Digital Repository (DR-NTU) is built upon an existing open source digital library framework for creating Web repositories. To facilitate individual content access and submission, we have implemented a domain directory service enabled single sign-on (SSO) authentication scheme for our digital repository. This paper describes our unique context oriented approach based on domain directory services for implementing such a SSO scheme. Our approach can be further extended to create authorization policies for users sharing common context under an institutional domain. The techniques described here will be useful for other Web repositories having similar SSO needs for secure authentication and would also facilitate developing an adaptable workflow for content submitters.
Design considerations leading to the development of good π-rotation LDPC codes (2005)

In this letter we present two theoretical results that lead to the development of good /spl pi/-rotation LDPC codes. The first theorem derives bounds on the weight of the parity vector when the weight of the information vector is two. The second theorem establishes the expected number of short-loops in the parity check matrix. Several performance examples are given.
