Interpolation search—a log log <i>N</i> search (1978)

Interpolation search is a method of retrieving a desired record by key in an ordered file by using the value of the key and the statistical distribution of the keys. It is shown that on the average log log N file accesses are required to retrieve a key, assuming that the N keys are uniformly distributed. The number of extra accesses is also estimated and shown to be very low. The same holds if the cumulative distribution function of the keys is known. Computational experiments confirm these results.
Stochastic analysis of virus transport in aquifers (1999)

A large‐scale model of virus transport in aquifers is derived using spectral perturbation analysis. The effects of spatial variability in aquifer hydraulic conductivity and virus transport (attachment, detachment, and inactivation) parameters on large‐scale virus transport are evaluated. A stochastic mean model of virus transport is developed by linking a simple system of local‐scale free‐virus transport and attached‐virus conservation equations from the current literature with a random‐field representation of aquifer and virus transport properties. The resultant mean equations for free and attached viruses are found to differ considerably from the local‐scale equations on which they are based and include effects such as a free‐virus effective velocity that is a function of aquifer heterogeneity as well as virus transport parameters. Stochastic mean free‐virus breakthrough curves are compared with local model output in order to observe the effects of spatial variability on mean one‐dimensional virus transport in three‐dimensionally heterogeneous porous media. Significant findings from this theoretical analysis include the following: (1) Stochastic model breakthrough occurs earlier than local model breakthrough, and this effect is most pronounced for the least conductive aquifers studied. (2) A high degree of aquifer heterogeneity can lead to virus breakthrough actually preceding that of a conservative tracer. (3) As the mean hydraulic conductivity is increased, the mean model shows less sensitivity to the variance of the natural‐logarithm hydraulic conductivity and mean virus diameter. (4) Incorporation of a heterogeneous colloid filtration term results in higher predicted concentrations than a simple first‐order adsorption term for a given mean attachment rate. (5) Incorporation of aquifer heterogeneity leads to a greater range of virus diameters for which significant breakthrough occurs. (6) The mean model is more sensitive to the inactivation rate of viruses associated with solid surfaces than to the inactivation rate of viruses in solution.
Engine Health Monitoring for engine fleets using fuzzy radviz (2013)

A new algorithm for assessment of Engine Health Monitoring (EHM) data in aircraft is proposed. The diagnostic tool quantifies step changes, shifts and trends in EHM data by means of a transformation that aggregates concurrent readings of EHM data into a single fuzzy state. A Genetic Fuzzy System is used to detect the occurance of a specific trend of interest in the sequence of states. The activation of the rules is represented in a 2D map by means of an extension of the Radviz visualization algorithm to fuzzy data.
Optimizing Facial Rejuvenation with a Combination of a Novel Topical Serum and Injectable Procedure to Increase Patient Outcomes and Satisfaction. (2017)

<b>BACKGROUND:</b> Neuromodulator injection procedures are an effective treatment for moderate-to-severe facial wrinkles, but do not address the superficial fine lines and wrinkles caused by age-related loss of intrinsic hyaluronic acid levels in the epidermis. <b>OBJECTIVE:</b> In this study, the authors assess overall facial skin quality and patient satisfaction when combining topical treatment with the a topical cosmetic serum (HA<sup>5</sup>) and applying to the entire face following a pre-elected neuromodulator injection treatment to the lateral canthal areas. <b>METHODS AND MATERIALS:</b> Twenty female subjects aged 36 to 63 years with moderate-to-severe under-the-eye fine lines and/or wrinkles enrolled in the study. HA<sup>5</sup> was applied the entire face at baseline immediately post-injection and twice daily for eight weeks. Clinical assessments were conducted at baseline; 15 minutes post-procedure; and at Weeks 2, 4, and 8. <b>RESULTS:</b> Statistically significant improvements were observed immediately post-procedure and after eight weeks, along with high patient satisfaction. <b>CONCLUSION:</b> The combination of topical serum and injectable procedure provided a rapid onset of improvements in fine lines/wrinkles appearance and skin texture and long-term overall improvements in areas not treated by the injection. These results support how this novel combination can provide physicians with a comprehensive approach to optimize patient outcomes.
Phospholipase A <sub>2</sub> , Hydroxyl Radicals, and Lipid Peroxidation in Transient Cerebral Ischemia (2003)

Phospholipid degradation is an important promoter of neuronal death after transient cerebral ischemia. Phospholipid hydrolysis by phospholipase A2 (PLA2) after transient cerebral ischemia releases arachidonic acid. Arachidonic acid metabolism results in formation of reactive oxygen species, lipid peroxides, and toxic aldehydes (malondialdehyde, 4-hydroxynonenal, and acrolein). Citicoline (cytidine-5'-diphosphocholine), an intermediate in phosphatidylcholine synthesis, has undergone 13 phase III clinical trials for stroke, and is being evaluated for treatment of Alzheimer's and Parkinson's diseases. Here we examined the effect of citicoline on PLA2 activity in relationship to attenuating hydroxyl radical (OH*) generation and lipid peroxidation after transient forebrain ischemia in gerbil. High Ca2+ dependency (millimolar range) of PLA2 activity suggests that secretory PLA2 is the predominant isoform in membrane and mitochondria. Citicoline attenuated the increase in PLA2 activity in both membrane and mitochondrial fractions. In vitro, citicoline and its components choline and cytidine had no effect on the PLA2 activity. Thus, citicoline is not a "direct PLA2 inhibitor." Citicoline also significantly attenuated loss of cardiolipin and arachidonic acid release from phosphatidylcholine and phosphatidylethanolamine. Transient cerebral ischemia resulted in significant formation of OH* and malondialdehyde, and citicoline significantly attenuated their formation. These results suggest that citicoline provides neuroprotection by attenuating the stimulation of PLA2.
Inducible processing of interferon regulatory factor-2. (1992)

PRDI-BFc and PRDI-BFi are proteins that bind specifically to a regulatory element required for virus induction of the human beta interferon (IFN-beta). PRDI-BFc is a constitutive binding activity, while the PRDI-BFi binding activity is observed only after cells are treated with inducers such as virus or poly(I).poly(C) plus cycloheximide or in some cells by cycloheximide alone. In this paper we report that PRDI-BFc is interferon regulatory factor-2 (IRF-2), a known transcriptional repressor. In addition, we find that PRDI-BFi is a truncated form of IRF-2, lacking approximately 185 C-terminal amino acids. Thus, PRDI-BFi appears to be generated by inducible proteolysis. Although the affinity of PRDI-BFc/IRF-2 for the IFN-beta promoter does not appear to be affected by the removal of C-terminal amino acids, the ability of PRDI-BFi to function as a repressor in cotransfection experiments is significantly less than that of intact IRF-2. Studies have shown that IRF-2 can block the activity of the transcriptional activator IRF-1, which also binds specifically to the IFN-beta gene promoter. Thus, the inducible proteolysis of IRF-2 may be involved in the regulation of the IFN-beta gene or of other genes in which the ratio of IRF-1 to IRF-2 can affect the level of transcription.
Concept for Measuring Laser Beam-Quality Parameters. (1998)

This paper provides brief descriptions of recent developments in the basic formulas and measurement methods for determining laser beam-quality. The M2 factor concept has been studied in order to describe the laser beam quality of real laser beams, including potentially multimode and arbitrarily distorted laser beams. The study shows that the M2 value can be determined by measuring the beam spot sizes around the beam-waist. In addition, various methods for measuring beam spot sizes are discussed. Finally, the beam quality of fiberbundled diode lasers is evaluated by the moving-slit method. A good agreement is obtained between the theoretical and experimental beam propagation results.
Bis(1-benzyl-4-aza-1-azoniabicyclo[2.2.2]octane) Peroxodisulfate: A Mild and Efficient Oxidant for Cleavage of Nitrogen Double Bonds and Oxidation of Alcohols under Anhydrous Conditions (1998)

Abstract Bis(1-benzyl-4-aza-1-azoniabicyclo[2.2.2]octane) peroxodisulfate (1), is readily prepared as an orange solid from commercially available 1,4-diazabicyclo[2.2.2]octane and potassium peroxodisulfate. This reagent easily converts hydrazones, semicarbazones, oximes, and alcohols to the corresponding carbonyl compounds with excellent yields.
Tailoring Chirp Characteristics of Waveguide Bragg Gratings Using Tapered Core Profiles (2006)

We propose and demonstrate the design principle of tapered core profiles for tailoring the chirp characteristics of waveguide Bragg grating (WBG) devices with uniform grating periods. Based on both numerical and experimental approaches, we establish the dependence of the modal effective index on the core width. We then design and fabricate polymeric WBG devices with a taper profile optimized for a linear group delay and those with a linear taper as well. Although they exhibit high ripples in their spectral responses due to incomplete structures, their chirp characteristics fit well the expected group delay curves

Efficient streaming of stereoscopic depth-based 3D videos (2013)

In this paper, we propose a method to extract depth from motion, texture and intensity. We first analyze the depth map to extract a set of depth cues. Then, based on these depth cues, we process the colored reference video, using texture, motion, luminance and chrominance content, to extract the depth map. The processing of each channel in the YC<sub>R</sub>C<sub>B</sub>-color space is conducted separately. We tested this approach on different video sequences with different monocular properties. The results of our simulations show that the extracted depth maps generate a 3D video with quality close to the video rendered using the ground truth depth map. We report objective results using 3VQM and subjective analysis via comparison of rendered images. Furthermore, we analyze the savings in bitrate as a consequence of eliminating the need for two video codecs, one for the reference color video and one for the depth map. In this case, only the depth cues are sent as a side information to the color video.

Characterization of 'non-N-methyl-d-Aspartate' binding sites for gacyclidine enantiomers in the rat cerebellar and telencephalic structures (2001)

Gacyclidine is a non-competitive NMDA receptor antagonist with potent neuroprotective properties. However, we have previously demonstrated that gacyclidine enantiomers [(-) and (+)GK11] interact with other ('non-NMDA') binding sites which may play a role in the lower self-neurotoxicity of this compound relative to the other NMDA receptor antagonists. Evidence for these binding sites has been obtained from autoradiographic and membrane binding experiments. They were found to be expressed at high levels in the molecular layer of the cerebellum, although they can also been seen in the granular layer and in telencephalic regions. The present study was designed to further characterize these gacyclidine 'non-NMDA' binding sites. The pharmacological profiles obtained on cerebellar and telencephalic membrane homogenates showed that they could not be linked directly to the main receptors or uptake complexes of the central nervous system (CNS). However, the comparison of (-) and (+)[(3)H]GK11 binding distribution in different mutant animals bearing specific cellular deficits in the cerebellum has demonstrated that the gacyclidine 'non-NMDA' binding sites are associated with the dendritic trees of Purkinje cells. Interestingly, our study also shows that the radioligand binding to both cerebellar and telencephalic structures could be modulated by endogenous factors which can be removed by a stringent prewashing procedure.
The fabrication and characterization of EEPROM arrays on glass using a low-temperature poly-Si TFT process (1996)

The fabrication and optimization of poly-Si thin-film transistors and memory devices on glass substrates at temperatures of 200/spl deg/C-400/spl deg/C is described, and the device characteristics and stability are discussed. The devices were formed using PECVD amorphous silicon, silicon dioxide, and silicon nitride films, and the crystallization of the amorphous silicon was achieved with an excimer laser. The performance of 16/spl times/16 EEPROM arrays with integrated drive circuits formed using this technology is presented.

Diels–Alder Cycloaddition in Protein Chemistry (2010)

Abstract The Diels–Alder reaction is probably, together with aldol condensation, the most commonly used reaction in chemistry. The Diels–Alder approach, which involves a diene and a dienophile not present in any biomolecule, allows a chemoselective reaction without the need of protecting groups. Moreover, water has an extraordinary rate‐accelerating effect on the reaction process. Thus, this chemical approach has been recognized as a promising procedure for protein bioconjugation. In this review some of the most recent advances in the application of the Diels–Alder reaction in selective surface modification, immobilization and biocatalysis will be discussed.
Influence of In-Well Convection on Well Sampling (2006)

Convective transport of dissolved oxygen (DO) from shallow to deeper parts of wells was observed as the shallow water in wells in South Carolina became cooler than the deeper water in the wells due to seasonal changes. Wells having a relatively small depth to water were more susceptible to thermally induced convection than wells where the depth to water was greater because the shallower water levels were more influenced by air temperature. The potential for convective transport of DO to maintain oxygenated conditions in a well was diminished as ground-water exchange through the well screen increased and as oxygen demand increased. Convective flow did not transport oxygen to the screened interval when the screened interval was deeper than the range of the convective cell. The convective movement of water in wells has potential implications for passive, or no-purge, and low-flow sampling approaches. Transport of DO to the screened interval can adversely affect the ability of passive samplers to produce accurate concentrations of oxygen-sensitive solutes, such as iron. Other potential consequences include mixing the screened-interval water with casing water and potentially allowing volatilization loss at the water surface. A field test of diffusion samplers in a convecting well during the winter, however, showed good agreement of chlorinated solvent concentrations with pumped samples, indicating that there was no negative impact of the convection on the utility of the samplers to collect volatile organic compound concentrations in that well. In the cases of low-flow sampling, convective circulation can cause the pumped sample to be a mixture of casing water and aquifer water. This can substantially increase the equilibration time of oxygen as an indicator parameter and can give false indications of the redox state. Data from this investigation show that simple in-well devices can effectively mitigate convective transport of oxygen. The devices can range from inflatable packers to simple baffle systems.
Structures of Human Alcohol and Aldehyde Dehydrogenases (1987)

Human alcohol dehydrogenase is a dimeric zinc metalloenzyme for which forms of three classes, I, II and III, have been distinguished. Subunits hybridize within but not between classes. There are three types of subunit, alpha, beta, and gamma, in class I. The primary structures of all three forms have been established, as well as the overall properties and the effects of the amino acid substitutions between the various forms. Each subunit has 374 residues, of which 35 exhibit differences among the alpha, beta and gamma chains. Corresponding cDNA structures are also known, as are the genetic organization and details of the gene structures. Allelic variants occur at the beta and gamma loci. Corresponding amino acid substitutions have been characterized, and enzymatic differences between the allelic forms are explained by defined residue exchanges. The results also illustrate recent and repeated isozyme evolution, a subject where alcohol dehydrogenases exceptionally well offer detailed examples. Human aldehyde dehydrogenase occurs of two types, a mitochondrial and a cytosolic form. The enzymes are tetramers, do not contain functional metals, and have subunits which do not form inter-type hybrids. The primary structures have been determined, revealing a positional identity of 68% (in 500 residues) between the mitochondrial and cytosolic forms. The N-terminus is heterogeneous and is not blocked in the subunit of the mitochondrial enzyme, in contrast to that of the cytosolic enzyme or those of all the alcohol dehydrogenases (also cytosolic). A reactive cysteine residue at position 302 has been ascribed functional importance at or close to the active site, is conserved in the two aldehyde dehydrogenases, and is associated with the action of disulfiram on the enzyme. In Oriental populations, a mutant allelic variant of the mitochondrial protein with impaired enzyme function has also been characterized.
