Preparation of 1-Aryl- or 1-Alkenyl-2-(perfluoroalkyl)acetylenes (1990)

Abstract 1-Aryl- or 1-alkenyl-2-(perfluoroalkyl)acetylenes were produced in high yields by the coupling reaction of aryl or alkenyl iodides with (perfluoroalkynyl)zinc compounds prepared from the corresponding (perfluoroalkyl)acetylenes in the presence of Pd catalyst.
Cost Savings at the Expense of Quality, Safety, and the Environment. A Plastic Molding Example (2006)

This paper uses plastic molded bobbins, headers and toroid mounts used in the electronics industry to highlight quality, safety and environmental trade-offs being made in favor of lower component costs. The trade-offs are often made without understanding the cost and risks being transferred from purchasing to more costly portions of the product manufacturing process, or to the customer.
The route of administration of an immunodominant peptide derived from heat‐shock protein 65 dramatically affects disease outcome in pristane‐induced arthritis (2000)

Previous studies have shown that immunization of mice with an immunodominant epitope from heat-shock protein 65 (hsp 65) (amino acids 261-271) can protect from the development of pristane-induced arthritis (PIA) and this protection is mediated by an antigen-specific T helper type 2 (Th2) cytokine response. Here we confirm these findings and show that frequent intranasal administration of this peptide exacerbates disease. In naive mice given peptide intranasally an antigen-specific T-cell population is systemically activated similar to that induced by peptide immunization in incomplete Freund's adjuvant. Thus, a paradox exists whereby apparently similar peptide-specific populations are either associated with protection from, or exacerbation of, PIA. However, comparison of cytokine profiles reveals differences between these two cell populations. Peptide inhalation induces the production of Th1-type cytokines (interferon-gamma) whereas intraperitoneal immunization leads to the production of Th2-type cytokines (interleukin-4, interleukin-5 and interleukin-10) by splenic T cells upon stimulation with peptide. Thus, for the application of nasal 'tolerance' in clinical medicine, it is important to identify antigens and dosing regimes that counteract but do not activate adverse immune responses.
Simulation studies of statistical distributions of cell membrane capacities and an ellipse model to assess the frequency behaviour of biological tissues (2013)

The frequency behaviour of biological tissues is commonly described by a Cole model reflecting a single-cell bio-impedance model extended with an exponent α. However, for this parameter α there is no physical or biological substrate, which impedes an interpretation. The present study confirms by computer simulations of tissue models that the factual frequency behaviour can be explained by assuming a distribution of the electrical impedance properties of cells and of the capacitive coupling between cells. This behaviour is modelled mathematically by an ellipse. A mathematical procedure is presented to estimate this ellipse from experimental data by a least square method. A model parameter β is introduced, representing the ratio of the axes of the ellipse. A higher value of β means a larger variation in cell properties, which makes a patho-physiological interpretation of changes possible.

Iterative algorithms for holographic shaping of non-diffracting and self-imaging light beams (2006)

We have developed iterative algorithms for the calculation of holograms for non-diffracting or self-imaging light beams. Our methods make use of the special Fourier-space properties of the target beams. We demonstrate experimentally the holographic generation of perhaps the most challenging type of beam: a self-imaging beam shaped in more than one plane. Potential applications include the generation of light "crystals" for optical trapping and atomic diffraction studies.
Thick Phase Holograms. (1981)

This report describes a two year research program to investigate thick phase holographic gratings. The first year effort primarily involved a study of hologram formation in dichromted gelatin. The results of that study can be found in the interim scientific report. The second year effort was a theoretical study of optical propagation through horizontally stratified, thick, phase reflection gratings. In this report, a general theory is developed for determining the complex reflection and transmission coefficients of such gratings as a function of incident angle, wavelength and polarization. Theorems are stated and proved about polarization effects and about the relationship between the spectral and angular characteristics of such gratings. The inverse scattering problem is considered. Given the spectral and angular characteristics of a horizontally stratified, quasi-sinusoidal, phases grating, first and second order approximate techniques are developed for determining the corresponding refractive index profile. It is also shown that horizontally stratified phase gratings can be used as position-invariant, frequency domain filters in coherent optical systems. Their basic filtering properties are presented. Finally, an interferometric technique is developed for fabricating horizontally stratified, quasi-sinusoidal, phase gratings.

Automated Density Separation for Freeze-Damaged Citrus (1988)

DURING the 1985 to 1986 citrus season in Florida, an automatic weight and dimensional sizer was used to differentiate freeze-damaged fruit based on density. The volume was computed from a digitized video camera image of the fruit as it traveled in a cup conveyor and the weight of the fruit was obtained from a load cell supporting an individual cup. Sorting errors on the weight/dimensional sizing unit were compared to a commercial process using hydrodynamic separation. Error rates ranged from 8.6 to 18.3% (weight/dimensional) and from 3.2 to 16.3% (hydrodynamic). Sources of error, specifically camera resolution and the equation for volume calculation, were analyzed.
Mobile boom cranes and advanced input shaping control (2008)

Millions of cranes are used around the world. Because of their wide-spread use in construction industries, boom cranes are an important class of cranes whose performance should be optimized. One limitation of most boom cranes is they are usually attached to a stationary base or a mobile base that is only used for initial positioning and not during operation. This limits the workspace of the boom crane significantly. If a boom crane was attached to a mobile base that could be safely used during lifting operations, then the boom crane workspace could be extended significantly.\n\nThe problem with using cranes, and in particular mobile cranes, is the large oscillations of the payload that are typically induced when moving the crane. One control strategy that has been used to control oscillation on other types of cranes is called Input Shaping, a command filtering technique that reduces motion-induced vibration in oscillatory systems.\n\nThis thesis develops a dynamics model for a mobile boom crane and analyzes the difficulty of controlling payload oscillation on a boom crane. Input shaping will shown to be effective for controlling oscillation on boom cranes. A new method for operating a boom crane in Cartesian coordinates will also be shown. This thesis will also detail the design of a small-scale mobile boom crane for experimental and research purposes.\n\nA substantial part of this thesis will also focus on the development of new input-shaping methods for nonlinear drive systems commonly found on boom and other types of cranes. An example application of a control system featuring input shaping for an industrial bridge crane will also be discussed.
Effect on bending behavior of counter cation species in perfluorinated sulfonate membrane–platinum composite (1998)

The perfluorinated sulfonate membrane (Nafion ®117)–platinum composites having H+, mono- and bivalent metal ions as counter cations in the membranes were prepared and the bending behaviors of the composites actuated by the step voltage were investigated in deionized water. The bending behaviors of all composites have the same tendency as the composites to bend quickly to the anode side just after applying the step voltage and gradually to bend back to the cathode side in spite of keeping on the application. However, they show differences in the bending rate and the maximum displacement to the anode side just after applying the step voltage, which are influenced by counter cation species in the membrane. In particular, the composite having Li+ has the largest maximum displacement (about 1.1 mm) to the anode side. The relationship between the maximum displacements of the composites and water states in the membranes were studied. The maximum displacements of the composites depend on the water content in the membranes. In both series of the composites having mono- and bivalent metal ions, the maximum displacements increase with increasing water content, except the composites having Rb+ and Sr2+ which belong to fifth period in the periodic table. In spite of the result that the water content in the membrane having H+, which is about 20wt%, is nearly equal to that in the membrane having Naa, the maximum displacement of the composite having H+ is only about one-third as large as that of the composite having Na+. The water structures in the membranes were investigated by using differential scanning calorimetry (DSC). The DSC endothermograms obtained indicate that the freezing water in the membrane having H+ has a much stronger interaction with sulfonate groups and counter cations than that in the membrane having Na+. It is concluded that the content and structure of the freezing water in the membrane have a profound effect on the bending behavior of the composite. © 1998 John Wiley & Sons, Ltd.
Cell-type specific activity of two glucocorticoid responsive units of rat tyrosine aminotransferase gene is associated with multiple binding sites for C/EBP and a novel liver-specific nuclear factor (1991)

The structures of two remote glucocorticoid responsive units (GRUs) that cooperatively interact to promote cell-type specific glucocorticoid induction of rat tyrosine aminotransferase gene expression have been analyzed. DNAase I footprinting and gel mobility shift analyses reveal a complex array of contiguous and overlapping sites for cell type-specific DNA binding proteins. Apart from the glucocorticoid receptor, two liver-specific nuclear factors possess multiple binding sites in each of these GRUs: C/EBP and a newly identified liver-specific factor: HNF5. C/EBP possesses four binding sites in each GRU; a DNA-binding protein with similar binding specificity has been identified in fibroblasts; this protein could be related to AP-3. HNF5 possesses two binding sites in one GRU and four in the other. There are also HNF5 binding sites in numerous regulatory regions of other liver-specific genes. The interaction of HNF5 with DNA gives a characteristic DNAase I footprint with hypersensitive sites in the middle of the recognition sequence. Some of the C/EBP and HNF5 binding sites overlap in a conserved arrangement.
The direct measurement bandwidth (1950)

Traditional methods of bandwidth measurement are based on somewhat arbitrary specifications, for example', the frequency difference between the high and low frequencies at which the single-tone response provides half the power corresponding to the frequency of maximum response. Other definitions of bandwidth or cut-off frequency are used in special cases whenever they seem appropriate. The lack of standardization in this matter creates confusion which is only now being resolved by the concept of equivalent bandwidth. A review of this concept is given to facilitate discussion of the measuring instruments described.
<title>New variable-rate VQ coding scheme apply in HDTV</title> (1990)

In this paper, a new approach of a variable block size VQ coding scheme is proposed. Most natural image can be divided into regions of high and low detail. Traditional coding schemes do not adapt the blocksize on the space-varying characteristics of natural images, but break the image into blocks of a fixed size prior to processing. The blocksize in transform coding is usually too large to handle partial high-detail region satisfactorily. On the other hand, the block size in conventional vector quantizer is too small to take advantage of large homogeneous regions in an image. For this reason, it can be very attractive to implement a variable block size image coding scheme which allow a greater variation of the number of bits spent per unit area according to the local detail.
Chromosome 22 tiling‐path array–CGH analysis identifies germ‐line‐ and tumor‐specific aberrations in patients with glioblastoma multiforme (2005)

Abstract Gliomas are common and frequently malignant tumors of the central nervous system. Recurrent allelic losses of chromosome 22 have been reported in gliomas, indicating tumor‐suppressor genes at this location. However, the target genes are still unknown. We applied a high resolution tiling‐path chromosome 22 array to a series of 50 glioblastoma samples, with the aim of investigating the underlying abnormalities in both constitutional and tumor‐derived DNA. We detected hemizygous deletions in 28% of the tumors (14 of 50), with monosomy 22 (10 of 50) being the predominant pattern. The distribution of overlapping hemizygous deletions delineated two putative tumor‐suppressor loci (11.1 and 3.08 Mb in size) across 22q. Most strikingly, we identified two distinct loci affected by regional gains. Both alterations were of germ‐line origin and were unique to samples from patients affected with tumors. Analysis of these two amplified regions revealed the presence of two interesting candidate genes: TOP3B and TAFA5 . The TOP3B gene encodes a protein that seems to function in the unlinking of parental strands at the final stage of DNA replication and/or in the dissociation of structures in mitotic cells that could lead to recombination. The TAFA5 gene belongs to a novel family of proteins with similarity to chemokines and brain‐specific expression. The role of the identified candidate loci should be studied further. Our results demonstrated the power of array‐CGH to determine DNA copy number alterations in the context of germ‐line‐ and tumor‐specific aberrations. © 2005 Wiley‐Liss, Inc.
Neural network fitness functions for a musical IGA (1996)

This paper describes recent enhancements to GenJam, a genetic algorithm-based model of a novice jazz musician learning to improvise. After presenting an overview and update of the current interactive version of GenJam, we focus on efforts to augment its human fitness function with a neural network, in an attempt to ease the fitness bottleneck inherent in musical IGAs. Specifically, a cascade correlation technique was used with data taken from populations of musical ideas trained by human mentors interactively. We conclude with a discussion of why this approach failed, and we speculate on approaches that might work. 1
Secure Enterprise Data Deduplication in the Cloud (2013)

With the advent of cloud computing as a new paradigm and technology, and the increased tendency of decision makers to envision a staged migration to cloud services, most enterprises are choosing to outsource their data to cloud storage providers, for better management of their IT resources, in terms of security, control, space and storage costs. In this context, assuming that the cloud service provider may not be trustworthy (i.e. is honest but curious), ensuring data privacy in all operations performed on enterprise data while these data reside in the Cloud is still a challenge. This paper proposes a novel twolevel data deduplication framework that can be used in cloud storage by enterprises. At the enterprise level, the enterprise performs cross-user data deduplication and outsources its data to the Cloud. At the cloud storage provider level, cross enterprise data deduplication is performed by the cloud service provider to further remove duplicates, resulting in cost and space savings. We argue that our framework will allow the enterprise to facilitate operations such as searching over encrypted data, sharing data within the enterprise, and downloading data from the Cloud directly, in a secure and efficient manner without the need to trust the cloud service provider.
Next generation Intel (2010)

Lincroft, the next generation Intel <sup xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">®</sup> ATOM™ processor based SoC specifically designed for smartphones, is fabricated in 45nm Hi-K metal gate CMOS. The design contains 140 million transistors in a die size of 65 mm <sup xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">2</sup> . Thermal design power (TDP) consumption is measured at 1.25W at 90°C at a frequency of 1.20GHz. Low power IO interfaces such as LPDDR1/DDR2, cDMI to IOH and cDVO for display are deployed to meet unique handheld SoC needs while consuming ultra low power. Clock architecture and clock distribution is configured with special power reduction features. As part of the extensive low power methodology, the chip is divided into numerous power domains with on die distributed powergates to reduce both active and standby power. Measured data shows up to 50X reduction in standby power. Silicon data shows dramatically low power in sleep and deeper sleep standby power states.
Rod sensitivity relative to cone sensitivity in retinitis pigmentosa. (1979)

The present study evaluates rod sensitivity relative to cone sensitivity in retinitis pigmentosa patients. From perimetric measures of absolute thresholds to long- and short-wavelength stimuli, we find the results can be characterized in three different ways. For one group of patients it appears that only cone function is present in all parts of the visual field. For another group of patients, despite large losses in absolute sensitivity, rod sensitivity still exceeds cone sensitivity by at least the normal factor, suggesting concomitant rod and cone sensitivity losses. For a third group of patients it appears that central retinal thresholds are determined primarily by cones, midperipheral retinal thresholds determined by a composite of rod and cone function, and far- peripheral thresholds determined predominately by rods. The argument is put forward that the different groups of threshold results represent different disease mechanisms rather than different stages in the progression of a single disease process.
Simulation-based multi-objective optimization of a real-world scheduling problem (2006)

This paper presents a successful application of simulation-based multi-objective optimization of a complex real-world scheduling problem. Concepts of the implemented simulation-based optimization architecture are described, as well as how different components of the architecture are implemented. Multiple objectives are handled in the optimization process by considering the decision makers' preferences using both prior and posterior articulations. The efficiency of the optimization process is enhanced by performing culling of solutions before using the simulation model, avoiding unpromising solutions to be unnecessarily processed by the computationally expensive simulation.
One‐dimensional solute transport in porous media with partial well‐to‐well recirculation: Application to field experiments (1990)

A solute transport model incorporating well‐to‐well recirculation was developed to facilitate the interpretation of pilot‐scale field experiments conducted for the evaluation of a test zone chosen for in situ restoration studies of contaminated aquifers, where flow was induced by recirculation of the extracted fluid. A semianalytical and an approximate analytical solution were derived to the one‐dimensional advection‐dispersion equation for a semi‐infinite medium under local equilibrium conditions, with a flux‐type inlet boundary condition accounting for solute recirculation between the extraction‐injection well pair. Solutions were obtained by taking Laplace transforms to the equations with respect to time and space. The semianalytical solution is presented in Laplace domain and requires numerical inversion, while the approximate analytical solution is given in terms of a series of simple nested convolution integrals which are easily determined by numerical integration techniques. The applicability of the well‐to‐well recirculation model is limited to field situations where the actual flow field is one dimensional or where an induced flow field is obtained such that the streamlines in the neighborhood of the monitoring wells are nearly parallel. However, the model is fully applicable to studies of solute transport through packed columns with recirculation under controlled laboratory conditions. The model successfully simulated tracer breakthrough responses at a field solute transport study, where an induced flow field superimposed on the natural gradient within the confined aquifer was created by a well pair with extraction to injection rates of 10:1.4.
Implementation of closed loop controller in a dual input DC-DC converter for DC-microgrid application (2016)

Hybridization of energy sources gives better reliability and flexibility for the power generation system. For integrating different sources, a suitable power electronic interface and a power management strategy are mandatory requirements. In this paper, implementation of closed loop controller for a dual input single output DC-DC converter to integrate two different VI characteristic sources for DC microgrid application is presented. The converter can perform all the three basic modes of operation of DC-DC converter (buck, buck-boost, and boost). The open loop and closed loop simulation of the proposed converter has been carried out in MATLAB Simulink platform and experimental validation is done with DSPIC30F3011 microcontroller for both open loop and closed loop operation. Effectiveness of control strategy is verified for both load regulation and line regulation. The experimental results are well matched with the simulation results which show the efficient operation of the control strategy adopted.
