Human Lung Cancer Cell Line Producing Hepatocyte Growth Factor/Scatter Factor (1992)

Hepatocyte growth factor (HGF)/scatter factor (SF) is a cytokine which is produced by mesenchymal cells and stimulates the motility of some epithelial cells, including cancer cells and vascular endothelial cells. Two human lung cancer cell lines, PC-1 and PC-13, were found to produce a protein which was indistinguishable from HGF/SF with regard to biological activities and immunological characteristics, although they were derived from epithelial cells. In general, highly aggressive cancer cells often show some mesenchymal characteristics, and production of HGF/SF by cancer cells is also considered as a phenomenon of acquisition of mesenchymal phenotype, which may be involved in cancer invasion and progression. These cell lines showed no apparent response to exogenous HGF/SF. In addition, no c-met proto-oncogene product was detectable in these cells by Western blot analysis. Although the function of HGF/SF produced by cancer cells, either autocrine or paracrine stimulation, remains to be studied, this is the first report to describe cancer cells producing HGF/SF.
Multiquadric equations of topography and other irregular surfaces (1971)

A new analytical method of representing irregular surfaces that involves the summation of equations of quadric surfaces having unknown coefficients is described. The quadric surfaces are located at significant points throughout the region to be mapped. Procedures are given for solving multiquadric equations of topography that are based on coordinate data. Contoured multiquadric surfaces are compared with topography and other irregular surfaces from which the multiquadric equation was derived.
Photostability of liquid crystals and alignment layers (2005)

Abstract— Photostability of liquid‐crystal (LC) materials and surface alignment layers was evaluated using a UV lamp and a blue laser beam. Both organic polyimide (PI) and inorganic silicon‐dioxide (SiO 2 ) alignment layers were studied under nitrogen environment. Two commercial TFT‐grade LC mixtures (low‐birefringence MLC‐9200‐000 and high‐birefringence TL‐216) were used for comparisons. Results indicate that SiO 2 alignment layers are much more robust than PI layers, and low birefringence LCs are more stable than the high‐birefringence ones. At the He‐Cd laser wavelength (λ = 442 nm), both LC mixtures and SiO 2 alignment layers are hardly damaged. To lengthen the lifetime of an LCD projector, inorganic SiO 2 alignment layers, high‐optical‐density UV filter, long cutoff‐wavelength blue filter, and short‐conjugation (low birefringence) LC materials should be considered.
Micro actuators for aligning optical fibers (2003)

Two microactuators to align fiber optics are described. One, an actuator using a thin strand of shape memory alloy, is used to align an input fiber with one of two output fibers. This component is useful for switching fiber-optic signals. The second is an electrostatic actuator capable of switching optical fibers and making fine adjustments to correct for misalignments. Single-point diamond machining (and associated molding technology) has been shown to be a viable alternative to etching Vee grooves in silicon for holding and aligning fibers.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">></ETX>

Oral vitamin D intake was associated with an increased risk for basal cell carcinoma, but not melanoma, according to two large cohort studies.
Gene expression profile linked to <i>p53</i> status in hepatitis C virus‐related hepatocellular carcinoma (2003)

To clarify the role of p53 in 22 hepatitis C virus (HCV)-infected hepatocellular carcinomas (HCCs), we compared the gene expression profiles of HCCs with wild-type p53 (wt-p53) (n=17) and those with mutant-type p53 (mt-p53) (n=5) by oligonucleotide microarray analysis. Among 83 p53-related genes identified by a supervised learning method, 25 were underexpressed, and 58 were overexpressed in mt-p53 HCCs compared with wt-p53 HCCs. With a computer search, we identified consensus p53-binding sequences in the 3-kb region upstream of the translation initiation site in 59 of the 83 genes, suggesting that the in vivo p53-associated transcription system is very complicated. These data will provide additional insights into p53-related pathogenesis in HCV-infected HCC.
A System for Checking Code Numbers on a Credit Card and a Paper of Personal Information (2009)

This paper presents a system for checking code numbers between on a credit card (CC) and a paper of personal information (PPI) using optical character recognition (OCR). The process starts to get both CC and PPI images from two cameras. Such both CC and PPI images are cropped with only the region of code numbers and then they are resized by linear interpolation. They are converted to binary images of value (0 or 1). Finally, the OCR is applied for checking the code numbers of the credit card and PPI. There are 100 samples for testing the credit card and PPI. Both credit cards and PPIs include 10 numbers (0 – 9). The result shows that the accuracy of the checking system on the credit card is at approximately 100%.
Visual Outcomes and Graft Thickness in Microthin DSAEK—One-Year Results (2015)

The microthin DSAEK procedure offers a simple and safe technique to prepare thin endothelial grafts with a low risk of graft wastage, low risk of postoperative detachment, and visual results that are comparable to those of other thin endothelial keratoplasty procedures.
Adaptive control of water level in real model of water tank (2015)

This paper shows control results of simulations on mathematical model and real measurements on the real model of the water tank. The level in the tank is controlled via input volumetric flow rate through the proportional solenoid valve. The adaptive approach with the recursive identification was employed here for controlling of this system. The controller could be tuned by the choice of the pole position in the pole-placement method. The benefit of this paper could be found also with the verification of the obtained simulation results on the real model of the water tank which shows usability of this control approach although the system has nonlinear properties. Control measurements also show hysteresis of the proportional solenoid valve which was used as an actuator in the control.
Certify&#x2014; A characterization and validation tool for behavioral models (2007)

Device modeling plays an important role in VLSI circuit design because computer-aided circuit analysis results are only as accurate as the models used. This indicates a need for robust tools that can facilitate the testing, validation and characterization procedure of semiconductor device models. Certify, the graphical tool for model characterization and validation, is a step in this direction [1]. The software architecture and different modules of Certify have been described in this paper.
Direct Observation of the Human Cerebral Microcirculation During Aneurysm Surgery Reveals Increased Arteriolar Contractility (2004)

OPS imaging allows direct in vivo observation of the cerebral microcirculation enabling us, for the first time, to visually observe and quantify microvascular reactivity in the human brain. The present study demonstrates increased contractile responses of the cerebral arterioles in the presence of subarachnoid blood, suggesting increased microvascular tonus with possibly greater susceptibility to ischemia.
Extending VSP to Three-Dimensional MWD: Using Drill Bit as Downhole Seismic Source: ABSTRACT (1989)

Vertical seismic profiling (VSP) has been used over the past decade to provide seismic images near well bore. A new well bore seismic technique, the TOMEX/reg sign/ Survey, uses the natural vibrations created by the drill bit during the drilling of a well as a downhole energy source. Since the TOMEX Survey requires no downhole instrumentation, it eliminates lost rig time and avoids the complications of open-hole wireline operations. These factors are important whenever rig time is expensive or the risk associated with open-hole operations are high. Furthermore, the ease with which surface receivers can be deployed makes multioffset surveys much more cost effective than conventional offset VSP.

Treatment of refractory erosive oral lichen planus with extracorporeal photochemotherapy: 12 cases (2006)

ECP is an effective alternative therapy in erosive OLP showing resistance to classical treatments. The decrease in blood lymphocyte counts appears to parallel the clinical improvement under treatment.
Aspects of the biology of billfish (lstiophoridae) from the equatorial western Indian Ocean* (1971)

A tuna longline survey of billfish was carried out in the equatorial western Indian Ocean during 1964‐67, in which 265 specimens of five species (Istiophorus platypterus, Tetrapterus audax, T. angustirostris, Makaira indica and M. nigricans) were caught. The comparative morphometric evidence obtained is used in confirming the conspecificity of these istiophorids with Pacific Ocean forms. However, the insufficient depth and detail of the data allow only preliminary observations on populational differences. The distribution and seasonal abundance of the species are discussed in terms of percentage catch rate. The weight‐length relations of the species are examined. The size composition of the catches is shown by the analysis of length and weight frequencies, and tentative estimates of the year classes present in the catches of T. audax are given. An examination of the sex ratio of the species is made. Gonad maturation indices for males and females are established, based on both macroscopic and histological evidence. The indices are used to study breeding in the species caught in the survey area. Relative gonad weight is also considered as a means of assessing the stage of gonad development. The results of the gonad examination indicate that little spawning occurs in the area, and it is suggested that seasonal abundance of certain species is related to feeding. Preliminary observations on the size at first maturity are made, and the fecundity of female I . platypterus, T. audax , and T. angustirostris is examined.
Optoelectronic Manipulation, Assembly, and Patterning of Nanoparticles (2009)

The synthesis of nanostructures has advanced in the last decade to a point where a vast range of insulating, semiconducting, and metallic materials are available in a variety of forms and shapes such as wires, tubes, ribbons, sheets, and spheres. These nanostructures display exceptional physical properties that can be used to realize novel devices such as high-speed electronics, efficient photovoltaics and thermoelectrics, sensitive chemical and biological sensors, nano-light sources such as lasers and light-emitting diodes, and high-frequency resonators. However, a persistent challenge has been the development of a general strategy for manipulation and heterogeneous integration of individual nanostructures with arbitrary shapes and compositions. Development of such methods is essential in transforming nano-sciences into successful nano-technologies that can ultimately affect the society. Several techniques such as microcontact printing, microfluidics, Langmuir-Blodgett, mechanical nano-manipulators, optical tweezers, and fixed-electrode dielectrophoresis have been developed to address this challenge. However, these techniques either lack the capability to manipulate single nanostructures or are unable to do so in a dynamic and large-scale fashion.Optoelectronic tweezers (OET) has emerged as a powerful tool for massively parallel manipulation of polymer-beads and living cells at micron length-scales via optically-induced dielectrophoresis. By combining the optical and electrical trapping capabilities, OET is able to manipulate particles with much lower optical intensities than optical tweezers and unlike fixed electrode dielectrophoresis, OET is capable of dynamic manipulation of single particles over large areas.In this dissertation, we will first introduce OET as an optofluidic platform and characterize the various electrokinetic forces that can be generated in the OET device. Next, we will use these forces for manipulation, sorting, assembly, and patterning of various nanostructures such as semiconducting and metallic nanowires, carbon nanotubes, and metallic spherical nanocrystals. Though the initial demonstrations of OET were limited to manipulation of microscale objects, here, we will explore the capabilities of OET for manipulation of nanoscale particles, establishing it as an important tool for post-synthesis organization and heterogeneous integration of nanostructures.
A Study on the Reliability and Stability of High Voltage 4H-SiC MOSFET Devices (2006)

Gate oxide reliability measurements of 4H-SiC DMOSFETs were performed using the Time Dependent Dielectric Breakdown (TDDB) technique at 175°C. The oxide lifetime is then plotted as a function of the electric field. The results show the projected oxide lifetime to be > 100 years at an operating field of ~3 MV/cm. Device reliability of 2.0 kV DMOSFETs was studied by stressing the gate with a constant gate voltage of +15 V at a temperature of 175°C, and monitoring the forward I-V characteristics and threshold voltage for device stability. Our very first measurements show very little variation between the pre-stress and post-stress conditions up to 1000 hrs of operation at 175°C. In addition, forward on-current stressing of the MOSFETs show the devices to be stable up to 1000 hrs of operation.
PVC‐clay nanocomposites: Preparation, thermal and mechanical properties (2001)

Abstract PVC‐clay nanocomposites were prepared by melt blending of the polymer with an organically modified clay, both in the presence and in the absence of di(2‐ethylhexyl) phthalate (DOP). The clay can serve as a plasticizer for PVC in the absence of DOP. The nanocomposites were characterized by using X‐ray diffraction and transmission electron microscopy, and the materials were found to be largely intercalated. Thermal properties were evaluated by using thermogravimetric analysis, and the thermal stability was determined to be variable, depending upon the amounts of clay and DOP that were present. The fraction of polymer that remained at 600°C was significantly reduced in the presence of the clay, a result indicating that the clay had an effect on the course of the degradation of the PVC. The tensile strength of the nanocomposites increased as the fraction of clay increased, and the addition of a small amount of clay increased the elongation, but when additional clay was added, the elongation decreased.
A network model for prediction of temperature distribution in data centers (2015)

We propose a novel network model for real-time prediction of temperature distribution in a data center so as to allow energy-efficient task assignment and facility management. We model various physical relationships in the data center as a network, including heat movements caused by airflow and heat generation by servers. Since changes in temperature distribution depend on physical properties of the data center such as equipment locations and server types, model parameters (connection weights in the network) that characterize relationship of nodes are determined by a machine learning technique using actual data center operation data. The proposed method provides prediction results in a shorter time than traditional methods such as model based on computational fluid dynamics and potential flow model, while maintaining prediction accuracy. We evaluate the performance of the proposed model through comparison with actual data from our experimental data center. The evaluation indicates that the proposed model can predict 10-minute future temperature distributions in 60 places in 3.3 ms, with a root mean square error of 0.49 degrees.
Market structure and bid-ask spreads: IBIS vs Nasdaq (1999)

A comparison is made between the bid-ask spreads of 30 high volume German stocks traded on IBIS and 30 high volume US stocks traded on Nasdaq. IBIS and Nasdaq are best described as agency and dealer auction markets, respectively. On average, the market spread for these IBIS and Nasdaq stocks is the same, but for the 10 most active stocks in each market, IBIS spreads are considerably lower. For these latter stocks, IBIS spreads change in a predictable manner throughout the day. Nasdaq spreads do not. The critical factor appears to be the unrestricted access of suppliers of immediacy that is distinctive for agency auction markets.
A TRAJECTORY-BASED APPROACH FOR THE LATERAL CONTROL OF VEHICLE FOLLOWING SYSTEMS (1998)

Abstract--- A crucial task for steering an autonomous vehicle along a safe path in a vehicle following scenario is the lateral control. The sensory input of such a lateral control are the position coordinates of the leader vehicle. The following problem occurs: Due to the distance between the leader vehicle and the autonomous ego-vehicle, the lateral control has to interpolate a trajectory between the twovehicles. Using as a trajectory either a straight line or a curve of constant curvature causes the ego-vehicle to deviate from the leader vehicle &apos;s trajectory. Given a system delivering 3D points of the leader vehicle with time tags, one has a handle to reconstruct the leader vehicle&apos;s trajectory. In addition, one has to compensate the motion of the ego-vehicle by using its motion parameters. Once this transformation is performed, the position coordinates of the leader vehicle are available in a coordinate system at rest. Knowing the position of the ego-vehicle in that coordinate sys...
Structured Illumination-Based Super-Resolution Optical Microscopy for Hemato- and Cyto-Pathology Applications (2013)

Structured illumination fluorescence microscopy utilizes interfering light and the moiré effect to enhance spatial resolution to about a half of that of conventional light microscopy, i.e. approximately 90 nm. In addition to the enhancement in the x and y directions, it also allows enhancement of resolution in the z - direction by the same factor of two (to approximately 220 nm), making it a powerful tool for 3-D morphology studies of fluorescently labeled cells or thin tissue sections. In this report, we applied this technique to several types of blood cells that are commonly seen in hematopathology. Compared with standard brightfield and ordinary fluorescence microscopy images, the 3-D morphology results clearly reveal the morphological features of different types of normal blood cells. We have also used this technique to evaluate morphologies of abnormal erythrocytes and compare them with those recorded on normal cells. The results give a very intuitive presentation of morphological structures of erythrocytes with great details. This research illustrates the potential of this technique to be used in hematology and cyto-pathology studies aimed at identifying nanometer-sized features that cannot be distinguished otherwise with conventional optical microscopy.
The Load-Sharing Banyan Network (1986)

Banyan networks, as well as many other self-routing networks, have a simple and regular topology, and can be easily diagnosed and maintained. However, like many other self- routing networks, Banyan networks have only one path between each input and output pair. Failures of a single link or node will make many paths unavailable, and certain traffic patterns can cause severe congestion in the networks.
5.5GHz system z microprocessor and multi-chip module (2013)

The new System z microprocessor chip (“CP chip”) features a high-frequency processor core running at 5.5GHz in a 32nm high-κ CMOS technology [1], using 15 levels of metal. This chip is a successor to the 45nm product [2], with significant improvements made to the core and nest (i.e. the logic external to the cores) in order to increase the performance and throughput of the design. Also, special considerations were necessary to ensure robust circuit operation in the high-κ technology used for implementation. As seen in the die photo, the chip contains 6 processor cores (compared to 4 cores in the 45nm version), and a large shared 48MB DRAM L3 cache. Each core includes a pair of data and instruction L2 SRAM caches of 1MB each. In addition, the chip contains a memory control unit (MCU), an I/O bus controller (GX), and two sets of interfaces to the L4 cache chips (also in 32nm technology). The CP chip occupies 598 mm <sup xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">2</sup> , contains about 2.75B transistors, and has 1071 signal IOs.
Genetic architecture of thermal adaptation in <i>Escherichia coli</i> (2001)

Elucidating the genetic basis of adaptation on a genomewide scale has evaded biologists, but complete genome sequences and DNA high-density array technology make genomewide surveys more tractable. Six lines of Escherichia coli adapted for 2,000 generations to a stressful high temperature of 41.5 degrees C were examined on a genomewide scale for duplication/deletion events by using DNA high-density arrays. A total of five duplication and deletion events were detected. These five events occurred in three of the six lines, whereas the remaining three lines contained no detectable events. Three of the duplications were at 2.85 Mb of the E. coli chromosome, providing evidence for the replicability of the adaptation to high temperature. Four candidate genes previously shown to play roles in stress and starvation survival were identified in the region of common duplication. Expression of the two candidate genes examined is elevated over expression levels in the ancestral lines or the lines without the duplication. In the two cases where the duplication at 2.85 Mb has been further characterized, the timing of the genome reorganization is coincident with significant increases in relative fitness. In both of these cases, the model for the origin of the duplication is a complex recombination event involving insertion sequences and repeat sequences. These results provide additional evidence for the idea that gene duplication plays an integral role in adaptation, specifically as a means for gene amplification.
