Quality and nutritional properties of pasta products enriched with immature wheat grain (2013)

In this study, nutritional and sensory properties of pasta enriched with 30% immature wheat grain (IWG), a natural source of fructo-oligosaccharides (FOS), are evaluated. Colour and cooking quality, nutritional value and glycaemic index (GI) of pasta were assessed in comparison with commercially enriched inulin and 100% wholewheat pastas. IWG integration induced deep changes in colour, without negatively affecting the cooking quality of pasta, and promoted nutritional quality by increasing the fibre content; IWG pasta presented a remarkable leaching of FOS in cooking water, thus providing only 1 g of FOS per serving. IWG pastas showed a GI of 67 (dried) and 79 (fresh), not significantly different from commercial pasta products. IWG can be considered an interesting ingredient to obtain functional products 'naturally enriched' in FOS and fibre. Results about FOS leaching suggest that, in dealing with functional effects, the actual prebiotic content should be carefully considered on food 'as eaten'.

A novel gate-overlapped LDD poly-Si thin-film transistor (1996)

We fabricate a new polycrystalline silicon thin-film transistor (poly-Si TFT), called a gate-overlapped lightly doped drain (GO-LDD) TFT, which reduces the leakage current without sacrificing the ON current. A new GO-LDD TFT, of which the electrical characteristics are tolerable to the change of LDD doping concentration, can be easily fabricated by employing the buffer oxide without any additional LDD implantation. The change of ON current due to the misalignment of the LDD region may be eliminated. Experimental results show that the leakage current of the proposed TFT's is reduced by two orders of magnitude, compared with that of conventional nonoffset TFT, while the ON current is not decreased. It is observed that the ON/OFF current ratio is not changed significantly with LDD doping concentration and LDD length.
3D scene on 2D screen: the VISUALCAD connection (1989)

Working with 3D space through the 2D computer screen is a skill that has to be mastered by CAD users. Current user interface designs fail to address the basic issue of relating the users' mental space with the computer's construction space. VISUALCAD, a new technique developed to communicate 3D CAD concepts, combines the users' mental space and the computers construction space. Through the use of video tools it enables us to discuss and demonstrate the key concepts in CAD all in one real space. The use of video is found to be an indispensable part of CAD training.
Adenosine stimulation of proliferation of breast carcinoma cell lines: Evaluation of the [<sup>3</sup>H]thymidine assay system and modulatory effects of the cellular microenvironment in vitro (2004)

The purine nucleoside adenosine is produced at increased levels in the tissues of solid cancers as a result of local hypoxia. Adenosine inhibits the cell-mediated anti-tumor immune response, promotes tumor cell migration and angiogenesis, and stimulates the proliferation of tumor cells. We examined the stimulatory effect of adenosine on DNA synthesis, cell cycle progression, and cell proliferation in MCF7 and T-47D breast carcinoma cell lines in culture, and identified factors that modulate the growth response. The ability of adenosine to stimulate DNA synthesis, as measured by the incorporation of [(3)H]thymidine, was independent of the total radioactivity of the [(3)H]thymidine up to 10 microCi/ml, total thymidine concentrations up to 100 microM, and the labeling interval. It was also not affected by the presence of low-molecular-weight compounds (such as thymidine and adenosine) in the serum used to supplement the medium. Adenosine stimulated DNA synthesis and cell proliferation with an EC(50) of 4-6 microM and a maximum response at 30-100 microM, when given as a single addition. The stimulatory effect of adenosine involved progression through the cell cycle and a genuine increase in cell number, in the absence of significant apoptotic or necrotic cell death. The mitogenic effect of adenosine was dependent upon the culture cell density, with an optimum adenosine response at around 50% of confluent density. The response was also highly dependent upon the form of the serum addition to the growth medium, with the best response elicited in the presence of low concentrations of nonfetal bovine serum, although adenosine was mitogenic under standard culture conditions. The effects of serum supplementation and cell density were not due to differences in the rate of adenosine metabolism by either serum or cellular enzymes, but appeared to result from changes in the sensitivity to adenosine of the cell population in response to environmental cues. We, therefore, find that adenosine is consistently mitogenic for human breast carcinoma cells, and that the [(3)H]thymidine incorporation assay is a valid measure of this response. The data are consistent with the stimulatory effect of adenosine on cell proliferation being modulated by the local cellular environment.
Object Recognition using 3D SIFT in Complex CT Volumes (2010)

The automatic detection of objects within complex volumetric imagery is becoming of increased interest due to the use of dual energy Computed Tomography (CT) scanners as an aviation security deterrent. These devices produce a volumetric image akin to that encountered in prior medical CT work but in this case we are dealing with a complex multi-object volumetric environment including significant noise artefacts. In this work we look at the application of the recent extension to the seminal SIFT approach to the 3D volumetric recognition of rigid objects within this complex volumetric environment. A detailed overview of the approach and results when applied to a set of exemplar CT volumetric imagery is presented.
Embryonic myogenesis pathways in muscle regeneration (2004)

Embryonic myogenesis involves the staged induction of myogenic regulatory factors and positional cues that dictate cell determination, proliferation, and differentiation into adult muscle. Muscle is able to regenerate after damage, and muscle regeneration is generally thought to recapitulate myogenesis during embryogenesis. There has been considerable progress in the delineation of myogenesis pathways during embryogenesis, but it is not known whether the same signaling pathways are relevant to muscle regeneration in adults. Here, we defined the subset of embryogenesis pathways induced in muscle regeneration using a 27 time-point in vivo muscle regeneration series. The embryonic Wnt (Wnt1, 3a, 7a, 11), Shh pathway, and the BMP (BMP2, 4, 7) pathway were not induced during muscle regeneration. Moreover, antagonists of Wnt signaling, sFRP1, sFRP2, and sFRP4 (secreted frizzled-related proteins) were significantly up-regulated, suggesting active inhibition of the Wnt pathway. The pro-differentiation FGFR4 pathway was transiently expressed at day 3, commensurate with expression of MyoD, Myogenin, Myf5, and Pax7. Protein verification studies showed fibroblast growth factor receptor 4 (FGFR4) protein to be strongly expressed in differentiating myoblasts and newly formed myotubes. We present evidence that FGF6 is likely the key ligand for FGFR4 during muscle regeneration, and further suggest that FGF6 is released from necrotic myofibers where it is then sequestered by basal laminae. We also confirmed activation of Notch1 in the regenerating muscle. Finally, known MyoD coactivators (MEF2A, p/CIP, TCF12) and repressors (Twist, Id2) were strongly induced at appropriate time points. Taken together, our results suggest that embryonic positional signals (Wnt, Shh, and BMP) are not induced in postnatal muscle regeneration, whereas cell-autonomous factors (Pax7, MRFs, FGFR4) involving muscle precursor proliferation and differentiation are recapitulated by muscle regeneration.
Précis of <i>How Children Learn the Meanings of Words</i> (2001)

Normal children learn tens of thousands of words, and do so quickly and efficiently, often in highly impoverished environments. In How Children Learn the Meanings of Words , I argue that word learning is the product of certain cognitive and linguistic abilities that include the ability to acquire concepts, an appreciation of syntactic cues to meaning, and a rich understanding of the mental states of other people. These capacities are powerful, early emerging, and to some extent uniquely human, but they are not special to word learning. This proposal is an alternative to the view that word learning is the result of simple associative learning mechanisms, and it rejects as well the notion that children possess constraints, either innate or learned, that are specifically earmarked for word learning. This theory is extended to account for how children learn names for objects, substances, and abstract entities, pronouns and proper names, verbs, determiners, prepositions, and number words. Several related topics are also discussed, including naïve essentialism, children's understanding of representational art, the nature of numerical and spatial reasoning, and the role of words in the shaping of mental life.
First-Principles Modeling of Ferroelectric Oxide Nanostructures (2006)

The aim of this Chapter is to provide an account of recent advances in the first-principles modeling of ferroelectric oxide nanostructures. Starting from a microscopic description of ferroelectricity in bulk materials and considering then, successively, different kinds of nanostructures (films, multilayers, wires, and particles), we try to identify the main trends and to provide a coherent picture of the role of finite size effects in ferroelectric oxides.
A general framework for constructing application cooperating system in Windows environment (2003)

We often need to discuss or modify the results generated by single-user CAD applications when they are applied to cooperative design. To our knowledge, however, almost all the existing cooperative systems or tools, such as shared white-board and application sharing, have some limitations when used for to such task. When considering these limitations, we have coined the term "Application Cooperating" which means to retain the original features of the single-user CAD applications and when using them collaboratively. To reduce redundant development, we have developed a framework that converts a single-user CAD application into a multi-user application. To achieve this we have developed a framework whereby the events occurring through interactions with the application, can be captured, distributed, and reassembled, in such a way as to allow single-user CAD applications to be used cooperatively without modifications to their source codes. This paper main discusses the architecture, events process and other relative problems pertaining to the above.
Mobile Augmented Reality to Enhance Customer Experience while Purchasing Furniture (2020)

With the rapid advancement in technology, the younger generations are more inclined to using their gadgets in almost all the activity they do. While buying furniture requires more consideration and is time-consuming, they tend to search for every information that they need on internet first, before taking further action of going to the physical store. Through the field research and interviews, it can be proven that customers in average need two or more trips before finally deciding to purchase. The proposed application is designed to help user find their way to the shop with a sufficient product knowledge and also reducing their consideration time to a faster purchase conversion. Augmented Reality will be used on the mobile application to let user see the color compatibility to the room and allow approximate size measuring. This is done by using a specific target size as a comparison to real life object size. Small size usability testing was conducted to several user, and the final result received great feedback as it was easily understood, self-explanatory and aided user to make decision faster. Eventually, the aim is that when the furniture arrives, customer will feel satisfied as a conclusion of their furniture purchase journey.
Per-stream jitter analysis in CBR ATM multiplexors (2002)

Constant bit rate (CBR) traffic is expected to be a major source of traffic in high-speed networks. Such sources may have stringent delay and loss requirements and in many cases, they should be delivered exactly as they were generated. A simple delay priority scheme will bound the cell delay and jitter for CBR streams, so that in the network switches, CBR traffic will only compete with other CBR traffic in the networks. We consider a multiplexor in such an environment. We provide an exact analysis of the jitter process in the homogeneous case. In this case, we obtain the complete characterization of the jitter process showing the inaccuracies of the existing results. Our results indicate that the jitter variance is bounded and never exceeds the constant /sup 2///sub 3/ slot. It is also shown that the per-stream successive cell inter-departures times are negatively correlated with the lag 1 correlation of - 1/2 . Higher order correlation coefficients are shown to be zero. Simple asymptotic results on per-stream behavior are also provided when the number of CBR streams is considered large. In the heterogeneous case, we bound the jitter distribution and moments. Simple results are provided for the computation of the bound on the jitter variance for any mix of CBR streams in this case. It is shown that streams with a low rate (large period) do experience little jitter variance. However, the jitter variance for the high-rate streams could be quite substantial.
UTD-based model for prediction of propagation path loss and shadowing variability in urban mobile environments (1997)

A new uniform-theory-of-diffraction- (UTD-) based approach for cellular-mobile-radio-propagation modelling is presented. Buildings are represented as conducting halfplanes or screens, and the model includes the effect of building-height variation along all intervening screens between base station and mobile. The proposed model has low computational complexity and could be applicable to small urban cells over regular terrain, with buildings of nonuniform height. It is shown that results from the model are in very close agreement with experimental observations, and that they accurately predict observed trends in the dependence of path loss and its variability on frequency, range, building-height variation and screen spacing.
Gene therapy for type 1 diabetes. New approaches. (2004)

Type 1 or insulin-dependent diabetes mellitus is a metabolic disease that results from the destruction of pancreatic beta-cells. Most patients receive subcutaneous insulin injections to reduce blood glucose levels. However, strict glucose control by multiple insulin injections is associated with an increased risk of hypoglycemia and weight gain, while a less strict glucose control is insufficient to prevent chronic complications such as nephropathy, neuropathy and retinopathy. Gene therapy holds a tremendous therapeutic potential to improve glycemic control by restoring endogenous insulin production. This review focuses on recent advances directed at producing insulin in an ectopic tissue as well as inducing pancreatic beta-cell neogenesis. The strategies include constitutive and promoter-regulated insulin expression in the liver; increasing hepatic glucose oxidation; insulin production from intestinal cells; and islet cell neogenesis in liver and pancreas.
An Approach in Building a Chemical Compound Search Engine in Oracle Database (2005)

A searching or identifying of chemical compounds is an important process in drug design and in chemistry research. An efficient search engine involves a close coupling of the search algorithm and database implementation. The database must process chemical structures, which demands the approaches to represent, store, and retrieve structures in a database system. In this paper, a general database framework for working as a chemical compound search engine in Oracle database is described. The framework is devoted to eliminate data type constrains for potential search algorithms, which is a crucial step toward building a domain specific query language on top of SQL. A search engine implementation based on the database framework is also demonstrated. The convenience of the implementation emphasizes the efficiency and simplicity of the framework.

Rapid and Quantitative Blood Analysis for Free Fatty Acids by Chemical Ionization Mass Spectrometry (1976)

Abstract A quantitative analysis of fatty acids in micro-samples of dried blood spots by chemical ionization mass spectrometry has been developed. Isotope determination was used as the quantitating technique using the corresponding deuterium labeled internal standards. The procedure yields excellent precision and accuracy as demonstrated by the analysis of known fatty acid mixtures and of both C12:0 to C18:0 acids and phytanic acid in the blood from patients.
Single amino acid substitutions on the surface of<i>Escherichia coli</i>maltose‐binding protein can have a profound impact on the solubility of fusion proteins (2001)

Proteins are commonly fused to Escherichia coli maltose-binding protein (MBP) to enhance their yield and facilitate their purification. In addition, the stability and solubility of a passenger protein can often be improved by fusing it to MBP. In a previous comparison with two other highly soluble fusion partners, MBP was decidedly superior at promoting the solubility of a range of aggregation-prone proteins. To explain this observation, we proposed that MBP could function as a general molecular chaperone in the context of a fusion protein by binding to aggregation-prone folding intermediates of passenger proteins and preventing their self-association. The ligand-binding cleft in MBP was considered a likely site for peptide binding because of its hydrophobic nature. We tested this hypothesis by systematically replacing hydrophobic amino acid side chains in and around the cleft with glutamic acid. None of these mutations affected the yield or solubility of MBP in its unfused state. Each MBP was then tested for its ability to promote solubility when fused to three passenger proteins: green fluorescent protein, p16, and E6. Mutations within the maltose-binding cleft (W62E, A63E, Y155E, W230E, and W340E) had little or no effect on the solubility of the fusion proteins. In contrast, three mutations near one end of the cleft (W232E, Y242E, and I317E) dramatically reduced the solubility of the same fusion proteins. The mutations with the most profound effect on solubility were shown to reduce the global stability of MBP.
Surface Brillouin scattering in semiconductor Fibonacci multilayers (1990)

Brillouin spectra from surface (Rayleigh) acoustic waves in a-Si:H/a-${\mathrm{SiN}}_{\mathit{x}}$:H (x\ensuremath{\simeq}0.94) Fibonacci multilayers have been measured with a tandem multipass Fabry-P\'erot interferometer. To make a detailed analysis for the observed surface (Rayleigh) waves, following Merlin et al. [Phys. Rev. Lett. 55, 1678 (1985)] and Dharma-wardana et al. [Phys. Rev. Lett. 58, 1761 (1987)], we have formulated the propagation of surface acoustic waves parallel to the surface of the quasiperiodic multilayers using the Fourier-transform method in the long-wavelength regime. We found that the obtained Brillouin spectra can be accounted for by this new derivation of the Fourier transform of the surface acoustic waves, but a rather fascinating feature for the phonon frequency is that it is slightly modified by quasiperiodic indices (n,m) or p. Such a modulation is attributed to the existence of a small but nonvanishing acoustic impedance. Our theoretical approach gives the correct order of amplitude modulation for surface (Rayleigh) waves within an error of 1%. We thereby obtain an overall understanding of the elastic properties of the Fibonacci multilayers.
Purification and Concentration of Betalaines by Ultrafiltration and Reverse Osmosis (1982)

ABSTRACT Beet juices prepared by solid‐liquid extractions were processed by ultrafiltration (UF) and reverse osmosis (RO) to 30°Brix at 20°C. De Danske Sukkerfabrikker (DDS) UF/RO Lab Module‐20 plate‐and‐frame system was used having a 0.72‐m 2 effective membrane area and pressures from 50‐40 bar. After prefiltering, pectinase treated juices were sequentially processed through 20,000 and 6,000 (UF) molecular weight (MW) cut‐off membranes. The UF purified products were then concentrated by RO processes on several types of cellulose acetate (CA) membranes, one with a 500 MW cut‐off and 70% NaCl permeability provided colorants that were separated from a majority of soluble solids. Addition of invertase to pectinase‐treated juices decreased flux but yielded a three‐fold increase in betalaine concentration on a dry weight basis. Betalaine concentration by UF and RO processes also halved nitrate level and greatly reduced flavor.
