Quantitation of rabbit corneal epithelial cell outgrowth on polymeric substrates in vitro. (1990)

The outgrowth of corneal epithelial cells onto a polymeric substrate is expected to be the primary event in the epithelialization of a synthetic corneal graft. To study the effects of polymer surface properties on corneal epithelial cell outgrowth, a quantitative in vitro cell outgrowth assay was done. Polymers with systematic variations in hydroxyl content were used as outgrowth substrates. These polymers were characterized by electron spectroscopy for chemical analysis for elemental surface composition and by captive air-bubble contact angle for surface wettability. Circular corneal buttons were punched from excised rabbit corneas, placed onto these substrates, and incubated in a hormonally enriched culture medium. Outgrowth of the epithelial cells was allowed to proceed onto the substrates for 4 days. The outgrowth areas were measured, and an outgrowth index was calculated for each substrate by comparing it with tissue culture polystyrene substrate. The highest outgrowth generally occurred on substrates with intermediate wettabilities (captive air-bubble contact angles of approximately 45-75 degree); it was less on substrates of lower or higher wettabilities. Protein coatings of albumin, immunoglobulin G (IgG), fibronectin, and culture medium were found to lower the wettabilities of native substrates. Albumin and IgG precoating were shown to reduce epithelial cell outgrowth; fibronectin precoating was shown to improve outgrowth on most substrates. These results suggest that epithelial cell outgrowth is influenced by both substrate and protein interactions.

Automated, Patient-interactive, Spinal Cord Stimulator Adjustment: A Randomized Controlled Trial (2003)

Automated, patient-interactive adjustment of implanted spinal cord stimulators is significantly more effective and more efficient than traditional manual methods of adjustment. It offers not only improved clinical efficacy but also potential cost savings in extending implanted battery life. It has the additional potential advantages of standardization, quality control, and record keeping, to facilitate clinical research and patient care. It should enhance the clinical application of spinal cord stimulation for the treatment of chronic intractable pain.
Isotypes of alpha-tubulin are differentially regulated during neuronal maturation. (1987)

The mRNAs for two isotypes of alpha-tubulin, termed T alpha 1 and T26, are known to be expressed in the rat nervous system. We have compared the expression of these two alpha-tubulin mRNAs during neural development, using RNA blotting and in situ hybridization techniques with probes directed against unique sequences of each mRNA. T alpha 1 mRNA is highly enriched in the embryonic nervous system but is markedly less abundant in the adult brain; T26 mRNA is expressed in many embryonic tissues with little change in abundance during development. Within the nervous system, T alpha 1 mRNA is enriched in regions with neurons actively undergoing neurite extension, such as the cortical plate, whereas T26 mRNA is relatively homogeneous in distribution, with some enrichment in proliferative zones. Expression of T alpha 1 mRNA is also increased in PC12 cells induced to differentiate and extend neurite processes by nerve growth factor. Taken together, the data indicate that T alpha 1-tubulin mRNA is expressed at high levels during the extension of neuronal processes. The abundant expression of T alpha 1-tubulin mRNA may therefore reflect either a means to increase the available pool of alpha-tubulin or a specific requirement for the T alpha 1 isotype for neurite extension.
Dense disparity maps in real-time with an application to augmented reality (2003)

This work presents a technique for computing dense disparity maps from a binocular stereo camera system. The methods are applied in an Augmented Reality setting for combining real and virtual worlds with proper occlusions. The proposed stereo correspondence technique is based oil area matching and facilitates an efficient strategy by using the concept of a three-dimensional similarity accumulator whereby occlusions are detected and object boundaries are extracted correctly. The main contribution of this paper is the way we fill the accumulator using absolute differences of images and computing a mean filter on these difference images. This. is. where the main advantages of the accumulator approach can be exploited, since all entries can be computed in parallel and thus extremely efficient. Additionally, we-perform an asymmetric correction step and a post-processing of the disparity maps that maintains object edges.
72.4: Hyperreality Head Dome Projector (HDP) using LED Light Source (2006)

Abstract In this paper, we developed a novel hyperreality display called the Head Dome Projector (HDP). The HDP is a head‐mounted display consisting of a dome‐shaped screen with a radius of 40 cm, a mobile projector with ultra‐wide projection lens and LED light sources. The main feature of the HDP is very wide viewing angle of 115 degrees horizontally by 80 degrees vertically without head tracking and 360 degrees by 360 degrees with head tracking. According to our objective evaluation comparing the HDP with a flat‐panel display (FPD), the HDP realizes hyperreality 1.5 to 2.5 points higher than that realized by an FPD in the case of ±5 level evaluation for HD motion images
Radiation-Induced Complications after Breast Cancer Radiation Therapy: a Pictorial Review of Multimodality Imaging Findings (2009)

The purpose of this pictorial essay is to illustrate the multimodality imaging findings of a wide spectrum of radiation-induced complications of breast cancer in the sequence of occurrence. We have classified radiation-induced complications into three groups based on the time sequence of occurrence. Knowledge of these findings will allow for the early detection of complications as well as the ability to differentiate tumor recurrence.

The modulatory effect of acid and pepsin on esophageal mucosal prostaglandin release may play a role in the development of reflux-related mucosal pathology.
Reduced spatially correlated noise influence using subspace source localization method FINES (2005)

We have developed a high resolution subspace approach for EEG source localization within a realistic geometry inhomogeneous head model. The present study aims to reduce the influence caused by spatially correlated noise from background activities using FINES. Computer simulations were conducted on the realistic geometry head volume conductor model and compared with the classic MUSIC algorithm. The FINES approach was also applied to source localization of motor potentials induced by the execution of finger movement in a human subject. The present results suggest that FINES is insensitive to spatially correlated noise, and has enhanced performance as compared with MUSIC.
Thymus Exosomes-Like Particles Induce Regulatory T Cells (2008)

Exosomes released from different types of cells have been proposed to contribute to intercellular communication. We report that thymic exosome-like particles (ELPs) released from cells of the thymus can induce the development of Foxp3(+) regulatory T (Treg) cells in the lung and liver. Thymic ELPs also induce the conversion of thymic CD4(+)CD25(-) T cells into Tregs. Tregs induced by thymic ELPs suppress the proliferation of CD4(+)CD25(-) T cells in vitro and in vivo. We further show that neutralization of TGF-beta in ELPs partially reverses thymic ELP-mediated induction of CD4(+)Foxp3(+) T cells in the lung and liver. This study demonstrates that thymic ELPs participate in the induction of Foxp3(+) Tregs. Also, TGF-beta of thymic ELPs might be required for the generation of Tregs in the peripheral tissues.
Additional lossless compression of JPEG images (2005)

The task of additional compression of images earlier coded using JPEG is considered. A novel efficient method for coding quantized DCT coefficients is proposed. It is based on coefficient separation into bit planes, taking into account correlation between the values of neighbor coefficients in blocks, between the values of the corresponding coefficients of neighbor blocks as well as between the corresponding coefficients of different color layers. It is shown that the designed technique allows for images already compressed by JPEG to additionally increase compression ratio by 1.3...2.3 times without introducing additional losses.
Flower-like LiMnPO4 hierarchical microstructures assembled from single-crystalline nanosheets for lithium-ion batteries (2012)

Well-defined three-dimensional hierarchical flower-like LiMnPO4 microspheres were successfully synthesized by a simple one step low-temperature solvothermal method. Each flower-like single crystalline microsphere consists of LiMnPO4 sheets self-assembled via a nucleation–dissolution–re-crystallization process under the influence of diethylene glycol molecules. It is found that the presence of glucose not only facilitates the formation of single crystalline LiMnPO4 but also gives rise to a uniform amorphous carbonaceous layer on the LiMnPO4 nanoplates. The lithium storage properties of the LiMnPO4 microspheres were investigated for its potential as a cathode material for lithium ion batteries. A possible growth mechanism was also proposed based on time-dependent experiments. This work provides an efficient route for designing a desirable micro-/nanostructure, which could also be extended to synthesize other phosphate (LiMPO4) hierarchical structures used in energy storage.
Pleomorphomonas oryzae gen. nov., sp. nov., a nitrogen-fixing bacterium isolated from paddy soil of Oryza sativa (2005)

Five strains of free-living diazotrophs isolated from rice were characterized by using a polyphasic approach. The strains were found to be very closely related, with 99-100 % 16S rRNA gene sequence similarity and DNA-DNA hybridization values greater than 70 %, suggesting that they represent a single species. When compared with other recognized species, they showed not more than 93 and 89 % similarity for the 16S rRNA and nifH gene sequences, respectively. Phylogenetic distances showed that these isolates were distinct from other taxa within the alpha-Proteobacteria. Chemotaxonomic characteristics of these isolates included the DNA G + C content (62.1-63.1 mol%), the major quinone system (Q-10), predominant fatty acids (18 : 1omega7c, cyclo 19 : 0omega8c and 16 : 0) and major hydroxy fatty acids (14 : 0 3-OH, 18 : 0 3-OH and 16 : 0 3-OH). Based on phylogenetic and phenotypic analyses, these isolates are considered to represent a novel genus and species, for which the name Pleomorphomonas oryzae gen. nov., sp. nov. is proposed. The type strain is F-7(T) (=IAM 15079(T) = ATCC BAA-940(T) = DSM 16300(T)).
A Method of Improving Photon Detection Efficiency of High Purity Germanium Cameras by including Double-Interaction Photopeak Events (1983)

We propose a method to utilize double-interaction photopeak events in high purity Germanium cameras to improve sensitivity with no apparent degradation in spatial resolution. This procedure is based on an energy comparison between the energy deposited at two interaction sites for photons of up to 255 keV. To determine the sensitivity improvement quantitatively, we simulated the photon transport process for 140 keV photons in detail for Ge detectors having thicknesses of 1.00 to 2.00 cm in 0.25 cm steps. Discrete HPGe cameras were modeled using pixel sizes of (1.0 mm)2, (1.5 mm)2, and (2.0 mm)2. Our results indicate sensitivity improvements of 29-42%, depending on detector thickness and pixel size.
A Comparison And Analysis Of Name Matching Algorithms (2007)

Names are important in many societies, even in technologically oriented ones which use e.g. ID systems to identify individual people. Names such as surnames are the most important as they are used in many processes, such as identifying of people and genealogical research. On the other hand variation of names can be a major problem for the identification and search for people, e.g. web search or security reasons. Name matching presumes a-priori that the recorded name written in one alphabet reflects the phonetic identity of two samples or some transcription error in copying a previously recorded name. We add to this the lode that the two names imply the same person. This paper describes name variations and some basic description of various name matching algorithms developed to overcome name variation and to find reasonable variants of names which can be used to further increasing mismatches for record linkage and name search. The implementation contains algorithms for computing a range of fuzzy matching based on different types of algorithms, e.g. composite and hybrid methods and allowing us to test and measure algorithms for accuracy. NYSIIS, LIG2 and Phonex have been shown to perform well and provided sufficient flexibility to be included in the linkage/matching process for optimising name searching.
Site‐directed mutagenesis of Lys<sup>600</sup> in phospho<i>enol</i>pyruvate carboxylase of <i>Flaveria trinervia</i>: its roles in catalytic and regulatory functions (1995)

Phosphoenolpyruvate carboxylases from various organisms contain two conserved lysine residues. In the C4 dicot Flaveria trinervia, one of these residues is Lys600. Converting this Lys600 to Arg600 or Thr600 mainly increased the Km values and but had minimal effect on the Vmax. The Km for PEP, Mg2+ increased by up to 3-fold in Arg600 and Thr600 but the Km (HCO3-) increased 9-fold in Thr600, suggesting that Lys600 might be associated with bicarbonate-binding. This lysine was not obligatory for enzyme activity although the wild-type protein showed higher activity at physiological pH and was less inhibited by malate than the two mutants.
Highly Effective Cell Equalization in a Lithium-Ion Battery Management System (2019)

This paper proposes a highly effective voltage cell equalization method for lithium-ion (Li-ion) battery management systems (BMSs) for several applications, such as nearly zero energy buildings, microgrids, and electric vehicles. The concept of the suggested method is the proper control of the charging current of each cell of a battery stack through the suitable regulation of the gate source of each cell's parallel-connected <sc xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">mosfet</small> . Thus, the <sc xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">mosfet</small> can act as a controllable current source for providing the proper equalization current according to the specific needs of each battery cell. The correct voltage level of the gate-source of each <sc xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">mosfet</small> is determined by a cell equalization controller through the comparison of the performance of each cell of a battery stack with the healthier cell, which is detected by an aging estimation algorithm based on the evaluation of the internal resistor and the capacity fade of each cell. Therefore, smoother and faster cell equalization is achieved compared to the conventional dissipative method. The practicality and the high effectiveness of the proposed cell equalization technique have been experimentally validated. Several experimental results are presented to demonstrate the operational improvements of the proposed cell equalization technique against the conventional one.

V-Type Nerve Agent Detection Using a Carbon Nanotube-Based Amperometric Enzyme Electrode (2005)

An enzyme electrode for the detection of V-type nerve agents, VX (O-ethyl-S-2-diisopropylaminoethyl methylphosphonothioate) and R-VX (O-isobutyl-S-2-diethylaminoethyl methylphosphonothioate), is proposed. The principle of the new biosensor is based on the enzyme-catalyzed hydrolysis of the nerve agents and amperometric detection of the thiol-containing hydrolysis products at carbon nanotube-modified screen-printed electrodes. Demeton-S was used as a nerve agent mimic. 2-(Diethylamino)ethanethiol (DEAET) and 2-(dimethylamino)ethanethiol (DMAET), the thiol-containing hydrolysis product and hydrolysis product mimic of R-VX and VX, respectively, were monitored by exploiting the electrocatalytic activity of carbon nanotubes (CNT). As low as 2 microM DMAET and 0.8 microM DEAET were detected selectively at a low applied potential of 0.5 V vs Ag/AgCl at a CNT-modified mediator-free amperometric electrode. Further, the large surface area and the hydrophobicity of CNT was used to immobilize organophosphorus hydrolase mutant with improved catalytic activity for the hydrolysis of the P-S bond of phosphothiolester neurotoxins including VX and R-VX nerve gases to develop a novel, mediator-free, membrane-free biosensor for V-type nerve agents. The applicability of the biosensor was demonstrated for direct, rapid, and selective detection of V-type nerve agents' mimic demeton-S. The selectivity of the sensor against interferences and application to spiked lake water samples was demonstrated.
Evidence that insect dorsal unpaired medican (DUM) neurons are octopaminergic (1975)

The dorsal unpaired median neuron innervating the extensor tibiae (DUMETi) of locusts and grasshoppers, as well as some other DUM neurons, cause long-term inhibition of the slow intrinsic rhythm of contraction of the muscle by releasing a neurohumoral agent. Large, (600 - 1900 A), dense-core vesicles are present in the nerve terminals. The inhibitory action is mimicked by infusioninto the leg of a minute (0.01 ml.) drop of locust saline containing a very low concentration (10(-6)M) of dopamine or noradrenaline, or an extraordinarily low concentration of octopamine (2.5 x 10(-9) M). The amplitude and frequency of the contractions slowly return to normal. Neither the cell body nor the neuron fluoresces with the Falck-Hillarp treatment, even after a period of ligature has caused an accumulation of vesicles. Octopamine does not fluoresce with this treatment. Accordingly, it is suggested that this neuron, and the other efferent DUM neurons, are octopaminergic.?23Author

Picosecond pulse generation from a synchronously pumped mode-locked semiconductor laser diode (1982)

A semiconductor laser diode was mode locked in an external cavity when synchronously pumped with 90-ps current pulses. Transform-limited optical pulses with a 10-ps pulse width and a peak power of 160 mW were produced. Operating characteristics of such a system are described.
Optimal update frequency model for physical machine state change and virtual machine placement in the cloud (2013)

Cloud computing is evolving into the default operational framework running modern data centers. Efficient data center operation is concerned with the total amount of energy consumed as well as assuring adequate resources are available to process all of the incoming work requests. Existing research has demonstrated several algorithms that can be used to determine the optimal number of resources required to service these requests. However, a key issue not addressed in these algorithms is determining the frequency of recalculating the number of required resources. Changing the required resources at a rate slower than the optimal update frequency results in lower energy efficiency due to the over allocation of resources. Changing the resources at a rate higher than the optimal frequency results in insufficient time for systems to change state, which results in SLA violations. In this paper, a stochastic optimization model is presented that determines the optimal update frequency for changing the states of the nodes of the cloud as well as determining the proper frequency for recalculating the maximum expected load, which improves the determination of the optimum number of resources required, therefore maximizes energy efficiency and minimizes SLA violations.
