Coating of glass and polycarbonate with aqueous two‐component polyurethane resin (2013)

ABSTRACT Hard polyurethane coatings combine several features as high flexibility and toughness, good chemical resistance, improved clarity, and spontaneous air‐drying. However, the coating design (thicknesses, interface pretreatments, substrate features, etc.) is often troublesome. In this respect, the present investigation deals with the application of high‐clarity polyurethane coatings on transparent glass and polycarbonates. In particular, the role of the coating thicknesses and, above all, of the different compliance of the substrates was investigated. Progressive mode scratch and dry sliding linear reciprocating tribological tests were carried out and scanning electron microscopy images were captured to analyze the deformation response of the polyurethane coatings. The experimental findings allow to better interpret the way to ruptures of the investigated coating systems and the mechanisms involved. Accordingly, new strategies to prevent them could be elicited. © 2013 Wiley Periodicals, Inc. J. Appl. Polym. Sci., 2014 , 131 , 40021.
Comparison of 111In-DOTA-Tyr3-octreotide and 111In-DTPA-octreotide in the same patients: biodistribution, kinetics, organ and tumor uptake. (1999)

The distribution and excretion pattern of 111In-DOTATOC resembles that of 111In-DTPAOC, and the uptake in somatostatin-receptor-positive organs and most tumors is higher for 111In-DOTATOC. If 90Y-DOTATOC shows an uptake pattern similar to 111In-DOTATOC, it is a promising radiopharmaceutical for peptide-receptor-mediated radiotherapy in patients with somatostatin-receptor-positive tumors.
Glycogen Synthase 1 ( <i>GYS1</i> ) Mutation in Diverse Breeds with Polysaccharide Storage Myopathy (2008)

GYS1 mutation causes PSSM in diverse breeds and is the predominant form of PSSM in Draft- and Quarter Horse-related breeds. False-positive diagnosis, as well as the possibility of a second glycogenosis in horses with neuromuscular disease (type 2 PSSM), might explain the absence of the GYS1 mutation in horses diagnosed with excessive glycogen accumulation in muscle.

Clinical Efficacy and Safety of Nerve-Sparing Radical Hysterectomy for Cervical Cancer: A Systematic Review and Meta-Analysis (2014)

NSRH may be a reliable technique for treating early cervical cancer. Available evidence suggests that it is better than RH for postoperative recovery of pelvic organ function and postoperative morbidity, while the two techniques involve similar clinical safety and extent of resection. These results should be considered preliminary since they are based on a relatively small number of controlled trials, most of which were non-randomized. The findings should be verified in larger, well-designed studies.
Adsorption and desorption kinetics of gallium atoms on<mml:math xmlns:mml="http://www.w3.org/1998/Math/MathML" display="inline"><mml:mn>6</mml:mn><mml:mi>H</mml:mi><mml:mo>−</mml:mo><mml:mi mathvariant="normal">SiC</mml:mi><mml:mn/><mml:mo>(</mml:mo><mml:mn>0001</mml:mn><mml:mo>)</mml:mo><mml:mn/></mml:math>surfaces (2000)

Gallium (Ga) surface adsorption and desorption kinetics on 6H-SiC(0001) are investigated using reflection high-energy electron diffraction. It is found that for Ga adsorption, a wetting layer bonds strongly to the SiC(0001) surface. Additional Ga atoms form droplets on top of the wetting layer. The Ga droplets behave like a metallic liquid. The activation energies for desorption are determined to be 3.5 eV for Ga in the wetting layer and 2.5 eV for Ga in the droplets. It is further found that the desorption of Ga atoms from the wetting layer follows a zero-order kinetics, i.e., the desorption rate is independent of the number of adsorbed atoms.

Spatial and Temporal Trends in PM<sub>2.5</sub>Organic and Elemental Carbon across the United States (2013)

The rural/remote IMPROVE network (Interagency Monitoring of Protected Visual Environments) and the Environmental Protection Agency's urban Chemical Speciation Network have measured PM 2.5 organic (OC) and elemental carbon (EC) since 1989 and 2000, respectively. We aggregated OC and EC data from 2007 to 2010 at over 300 sites from both networks in order to characterize the spatial and seasonal patterns in rural and urban carbonaceous aerosols. The spatial extent of OC and EC was more regional in the eastern United States relative to more localized concentrations in the West. The highest urban impacts of OC and EC relative to background concentrations occurred in the West during fall and winter. Urban and rural carbonaceous aerosols experienced a large (although opposite) range in seasonality in the West compared to a much lower seasonal variability in the East. Long-term (1990–2010) trend analyses indicated a widespread decrease in rural TC (TC = OC + EC) across the country, with positive, though insignificant, trends in the summer and fall in the West. Short-term trends indicated that urban and rural TC concentrations have both decreased since 2000, with the strongest and more spatially homogeneous urban and rural trends in the West relative to the East.
Lattice Constants and Dielectric Properties of Barium Titanate—Barium Stannate—Strontium Titanate Bodies (1952)

Lattice constants and temperatures corresponding to maximum dielectric permittivity were investigated for compositions in the barium titanate‐rich portion of the system barium titanate–barium stannate–strontium titanate. Substitution of tin for titanium increases the lattice constant at room temperature, and substitution of strontium for barium decreases this parameter. Both types of substitution decrease the Curie temperature; tin is about twice as effective as strontium in this regard. Properties of bodies containing both tin and strontium are intermediate between those of bodies containing either alone.

A method of motion analysis using spatiotemporal image‐directional temporal plane transform (1995)

Abstract Some of the recent image processing methods proposed for detecting object moving in 3‐D space form a spatiotemporal image by placing consecutive camera images side by side in temporal order. This paper presents one such method, the directional temporal plane transform method (DTT), an image processing method that is not influenced by environmental changes. Assuming that the objects are moving on a nearly constant path, DTT first extracts significant data about these objects from each image, and then makes a 1‐D data stream by projecting the data long a directional axis parallel to the moving loci. After that, by placing the 1‐D data from individual frames side by side in temporal order, the spatiotemporal image is transformed into a 2‐D image on a directional temporal plane. Since the object motion is represented by regions of this 2‐D image, moving objects can be detected by simple 2‐D image processing. This method was used on an experimental basis to detect vehicles running along a road. Experimental results show the effectiveness of the method. An advantage of this method is its ability to detect vehicles using the same processing during both daytime and nighttime—a feature that has not been achieved with conventional methods.
Retina-like processing and coding platform for cortical neuro-stimulation (2004)

This paper describes a bio-inspired preprocessing and coding system devised for proper multielectrode stimulation at the primary visual cortex. After an introduction of the software/hardware (Sw/Hw) retina-like preprocessor as well as the system that produces a continuously varying stream of spike patterns, the paper presents a comparison of the system responses when only spatial or a combined spatio-temporal visual processing are modeled. The system is implemented both in software and in reconfigurable hardware. The main target of this work is to build, in a near future, a portable system for a neuro-prosthesis able to stimulate efficiently an array of intra-cortical implanted electrodes. The Sw/Hw platform is highly programmable and reconfigurable as required for experimentation, providing real-time neuromorphic stimulation able to be particularized for each implanted blind individual.
Mechanochemical Synthesis of Carbon Fluorides (2008)

Synthesis of electrochemically active carbon fluorides was achieved through the high-energy milling of graphite or carbon black with at room temperature. The carbon fluorides were characterized by elemental analysis, X-ray diffraction, IR, and X-ray photoelectron spectroscopy. The results for the carbon fluoride powder prepared from graphite are reported here. This material, with the formula , appears to have both semi-ionic and covalent CF bonds and demonstrates many of the characteristics of low-temperature carbon fluorides. The material has a high discharge potential of vs and a discharge capacity in the range of .
Understanding Video Events: A Survey of Methods for Automatic Interpretation of Semantic Occurrences in Video (2009)

Understanding video events, i.e., the translation of low-level content in video sequences into high-level semantic concepts, is a research topic that has received much interest in recent years. Important applications of this paper include smart surveillance systems, semantic video database indexing, and interactive systems. This technology can be applied to several video domains including airport terminal, parking lot, traffic, subway stations, aerial surveillance, and sign language data. In this paper, we identify the two main components of the event understanding process: abstraction and event modeling. Abstraction is the process of molding the data into informative units to be used as input to the event model. Due to space restrictions, we will limit the discussion on the topic of abstraction. See the study by <i xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">Lavee</i> <i xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">et</i> <i xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">al.</i> (Understanding video events: A survey of methods for automatic interpretation of semantic occurrences in video, Technion-Israel Inst. Technol., Haifa, Israel, Tech. Rep. CIS-2009-06, 2009) for a more complete discussion. Event modeling is devoted to describing events of interest formally and enabling recognition of these events as they occur in the video sequence. Event modeling can be further decomposed in the categories of pattern-recognition methods, state event models, and semantic event models. In this survey, we discuss this proposed taxonomy of the literature, offer a unifying terminology, and discuss popular event modeling formalisms (e.g., hidden Markov model) and their use in video event understanding using extensive examples from the literature. Finally, we consider the application domain of video event understanding in light of the proposed taxonomy, and propose future directions for research in this field.
KIR2DL4 (CD158d), an NK Cell-Activating Receptor with Inhibitory Potential (2002)

KIR2DL4 (CD158d) is an unusual member of the killer cell Ig-like receptor family expressed in all NK cells and some T cells. KIR2DL4 activates the cytotoxicity of NK cells, despite the presence of an immunoreceptor tyrosine-based inhibition motif (ITIM) in its cytoplasmic tail. The role of this ITIM on the activating function of KIR2DL4, and whether it can provide inhibitory signals, is not known. Mutated forms of KIR2DL4 were engineered that lacked either the tyrosine in the ITIM or an arginine-tyrosine motif in the transmembrane region that is required for the activation signal. The activity of the mutated KIR2DL4 molecules was tested in a redirected lysis assay. The ITIM was not necessary for activation of lysis by KIR2DL4. The activation signal of KIR2DL4 was sensitive to inhibition by another ITIM-containing receptor. The activation-deficient mutant of KIR2DL4 inhibited the signal delivered by the activating receptor CD16. In pull-down experiments with GST fusion proteins, the tyrosine-phosphorylated cytoplasmic tail of KIR2DL4 bound the Src homology 2-containing phosphatases 1 and 2, as did the tail of the inhibitory receptor KIR2DL1. Therefore, KIR2DL4 has inhibitory potential in addition to its activating function.
Simultaneous imaging of oxygen tension and blood flow in animals using a digital micromirror device (2010)

In this study we present a novel imaging method that combines high resolution cerebral blood flow imaging with a highly flexible map of absolute pO(2). In vivo measurements of pO(2) in animals using phosphorescence quenching is a well established method, and is preferable over electrical probes which are inherently invasive and are limited to single point measurements. However, spatially resolved pO(2) measurements using phosphorescence lifetime quenching typically require expensive cameras to obtain images of pO(2) and often suffer from poor signal to noise. Our approach enables us to retain the high temporal resolution and sensitivity of single point detection of phosphorescence by using a digital micromirror device (DMD) to selectively illuminate arbitrarily shaped regions of tissue. In addition, by simultaneously using Laser Speckle Contrast Imaging (LSCI) to measure relative blood flow, we can better examine the relationship between blood flow and absolute pO(2). We successfully used this instrument to study changes that occur during ischemic conditions in the brain with enough spatial resolution to clearly distinguish different regions. This novel instrument will provide researchers with an inexpensive and improved technique to examine multiple hemodynamic parameters simultaneously in the brain as well as other tissues.
Combined Treatment With Dichloroacetic Acid and Pyruvate Reduces Hippocampal Neuronal Death After Transient Cerebral Ischemia (2018)

Transient cerebral ischemia (TCI) occurs when blood flow to the brain is ceased or dramatically reduced. TCI causes energy depletion and oxidative stress, which leads to neuronal death and cognitive impairment. Dichloroacetic acid (DCA) acts as an inhibitor of pyruvate dehydrogenase kinase (PDK). Additionally, DCA is known to increase mitochondrial pyruvate uptake and promotes glucose oxidation during glycolysis, thus enhancing pyruvate dehydrogenase (PDH) activity. In this study, we investigated whether the inhibition of PDK activity by DCA, which increases the rate of pyruvate conversion to adenosine triphosphate (ATP), prevents ischemia-induced neuronal death. We used a rat model of TCI, which was induced by common carotid artery occlusion (CCAO) and hypovolemia for seven minutes while monitoring the electroencephalography (EEG) for sustained isoelectric potential. Male Sprague-Dawley rats were given an intraperitoneal injection of DCA (100 mg/kg) with pyruvate (50 mg/kg) once per day for two days after insult. The vehicle, DCA only or pyruvate only-treated rats were injected on the same schedule. Our study demonstrated that the combined administration of DCA with pyruvate significantly decreased neuronal death, oxidative stress, microglia activation when compared with DCA or pyruvate injection alone. These findings suggest that the administration of DCA with pyruvate may enhance essential metabolic processes, which in turn promotes the regenerative capacity of the post-ischemic brain.
<sup>13</sup>C‐NMR Studies of <i>Corynebacterium melassecola</i> Metabolic Pathways (1995)

Coryneform bacteria are widely used to produce amino acids, in particularly glutamic acid, by fermentation. To study the metabolic fate of glucose as the carbon source, we developed a method to analyze intracellular extracts by NMR and HPLC. The intracellular metabolites represent the metabolic state of the cells. Glutamic acid was the major metabolic intermediate found in the extracts and its 13C isotopic enrichment reflected that of pyruvic acid. Thus, it was possible to determine the respective contributions of the two major glucose catabolic pathways during the exponential growth phase; glycolysis (55%) and the pentose phosphate pathway (45%). Absolute glutamate 13C enrichments resulting from the incorporation of [1-13C]glucose were determined to quantify the contribution of several metabolic pathways such as anaplerotic pathways (61%; phosphoenolpyruvate carboxylase, pyruvate carboxylase, malic enzyme), a single turn (32%) or multiple turns of the Krebs cycle and the glyoxylate shunt, to oxaloacetate synthesis. A previously described model was adapted to C. melassecola for these calculations. The Krebs cycle was active, whereas the glyoxylate shunt was inactive in exponentially growing cells of C. melassecola with glucose as the sole carbon source. The contributions of anaplerotic enzymes and pyruvate dehydrogenase to replenishing the Krebs' cycle were determined to be 38% and 62%, respectively.
Functional Laser Trimming: An Overview (1986)

Laser trimming of hybrid circuits, and more recently, monolithic IC's is often used to improve yields and/or device performance. As device technology advances, trim technology continues to evolve and now offers spot sizes under 4μm, positioning accuracy to lμm, positioning speed of a few ros, and field coverage of up to 8 inches; addressing such diverse applications as VLSI memory repair, and complete PC board assembly trimming. Increased automation in the form of fully automatic device loading, alignment and beam focus are resulting in vastly improved thruput and lowered manufacturing costs. New, faster, and more accurate instrumentation is being introduced to trim the new mixed digital/linear parts beyond the traditional restriction to simple passive resistance and functional DC trimming. Furthermore, trimmable device design has emerged from the "black art" catagory and predictable results can now be achieved. However, gaining familiarity with all aspects of functional trimming is a formidable task and this is a major reason more manufacturers haven't added laser trimming to their bag of tricks.

A two-dimensional transistor placement for cell synthesis (2002)

Proposes a transistor placement algorithm to generate standard cell layout in a 2D placement style that is not restricted to row-based transistor placement. The cost function constructed for transistor placement optimization is able to optimize wirings directly and diffusion sharing indirectly but sufficiently. This transistor placement algorithm, applied to several standard cells, has demonstrated the capability to generate a nearly-optimal 2D placement that is comparable to manually designed placement.
