Validation of inverse lithography technology (ILT) and its adaptive SRAF at advanced technology nodes (2008)

In this paper, an overview of Inverse Lithography Technology (ILT) based on Level Set Methods (LSM) is provided. Applications of ILT in the advanced lithography process are then shown for several different devices, including DRAM, SRAM, FLASH, random logic, and imaging devices. ILT is used to correct the main patterns, as well as automatically insert SRAFs using model-based mathematical methods. The process of SRAF generation in ILT is unified with the process of inversion. With the help of ILT, SRAFs can be inserted where physically needed, independent of source parameters or target patterns. Results that demonstrate the adaptive nature of ILT SRAF insertion capability are presented. Wafer verification results were collected by multiple advanced semiconductor manufacturing companies at advanced technology nodes, including 45nm and 32nm nodes, and compared with their current OPC solution. Final wafer results presented here demonstrate that ILT improves pattern fidelity, enlarges process window, and provides remarkable control for line-end shortening.
Chromosomal Aberrations Associated with Mutations to Bacteriophage Resistance in <i>Escherichia coli</i> (1965)

Curtiss, Roy, III (University of Chicago, Chicago, Ill., and Oak Ridge National Laboratory, Oak Ridge, Tenn.). Chromosomal aberrations associated with mutations to bacteriophage resistance in Escherichia coli. J. Bacteriol. 89:28-40. 1965.-Ten types of mutants of Escherichia coli K-12 resistant to bacteriophage T(3) have been isolated, and several of these types have been studied genetically. Many of the /3,4,7, /3,4,7,lambda, and /3,4,7,lambda,pro(-) (1,2) mutants were unstable, changing to complete sensitivity to T(4). The results with strains having /3,4,7,lambda,pro(-) (1,2) mutations were compatible with the hypothesis that this mutation caused a single break in the circular chromosome which prevented the normal association in the inheritance of the outside markers leu(+) and lac(+). When sensitivity to T(4) was regained, association in the inheritance of outside markers was restored, and the resulting /3,7,lambda,pro(-) (1,2) mutation behaved genetically as a deletion. The /3,7,lambda,pro(-) (1,2) and /3,4,7,lambda,pro(-) (1,2) mutations caused positive interference, inhibition of genetic recombination in regions adjacent to them, and the formation of unstable partial diploid recombinants. One group of /3,4,7,lambda mutations did not occur in the leu to try region of the bacterial genome. Other /3,4,7,lambda mutations in F(-) bacteria prevented the joint inheritance of the outside markers lac(+) and gal(+), presumably by breakage of the circular chromosome. Hfr and F(+) strains with /3,4,7,lambda mutations at this locus were unable to conjugate; therefore, a complete genetic analysis of the effects of this /3,4,7,lambda mutation could not be done.
Some properties of elastodynamic eigensolutions in stratified media (1983)

In this note, we consider some symmetries of the coefficient matrix in the differential system for the displacement-stress vector in stratified media. These symmetries are used to obtain extremely simple relations between the elements of an associated eigenvector matrix and the elements of the inverse of this matrix. These results obtain in lossless but otherwise arbitrary elastic solids and, in particular, they hold for anisotropic media, obviating numerical calculation of the inverse eigenvector matrix in this case. The relations are closely tied to the notion of vertical energy flux normalization for eigensolutions associated with pure imaginary eigenvalues, but a different normalization naturally arises when the eigenvalues have a non-zero real part. The new normalization can be easily related to vertical energy flux normalization for travelling waves.
A novel agent based match making algorithm in multi-tenant architecture (2015)

Multi-tenant is an architecture which allows multiple tenants (customers) to share a single instance of a software application. Resource demand for each and every tenant will differ. For satisfying the tenants demand, the software application will take varying response time. By applying the appropriate load balancing algorithm among the tenants we can reduce the response time and also increase the resource utilization. Load balancing is a technique that distributes the excess dynamic local workload evenly across all nodes. This algorithm consists of different types of agents, which considers network proximity, live task migration and the needed properties of VM for optimal fitness functions evaluation. Thus, we have formed the basis for balancing the load across multiple servers. The implementation of this algorithm in multi-tenant will reduce operational cost, migration time, down time and also increases the resource utilization which results in optimal task placement.
Variation in Aggressiveness of<i>Xanthomonas campestris</i>pv.<i>citrumelo</i>Associated with Citrus Bacterial Spot in Florida Citrus Nurseries (1990)

(...) In one nursery, where strains varied from weakly to moderately aggressive, aggressiveness differed among separate disease foci. Strains from 25 unrelated nursery infestations were evaluated, and the most aggressive strains occurred in only four nurseries. More than 75% of the nursery outbreaks were associated with Swingle citrumelo. This variety was more susceptible than Duncan grapefruit to the aggressive strain of X. c. citrumelo and less susceptible to X. c. citri in attached leaf tests. There were significant interactions of strains of X. c. citrumelo of different aggressiveness with the two citrus cultivars
Distributed code assignments for CDMA packet radio networks (1993)

Code-division multi-access (CDMA) techniques allow many users to transmit simultaneously in the same band without substantial interference by using approximately orthogonal (low cross-correlation) spread-spectrum waveforms. Two-phase algorithms have been devised to assign and reassign spread-spectrum codes to transmitters, to receivers and to pairs of stations in a large dynamic packet radio network in polynomial times. The purpose of the code assignments is to spatially reuse spreading codes to reduce the possibility of packet collisions and to react dynamically to topological changes. These two-phase algorithms minimize the time complexity in the first phase and minimize the number of control packets needed to be exchanged in the second phase. Therefore, they can start the network operation in a short time, then switch to the second phase with the goal of adapting to topological changes. A pairwise code-assignment scheme is proposed to assign codes to edges. Simulations based on well-controlled topologies (sparse topologies) show that the scheme requires much fewer codes than transmitter-based code assignment, while maintaining similar throughput performance.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">></ETX>
The effect of a mechanical venous pump on the circulation of the feet in the presence of arterial obstruction. (1978)

A boot of single layer, flexible vinyl sheeting and a pneumatic cuff encircling its top at the ankle, each independently inflatable, constitute a mechanical venous pump. Inflation of the cuff to the desired boot pressure is followed immediately by inflation of the boot from a reservoir with higher available pressure than that in the cuff. When the boot pressure reaches cuff pressure, the excess air escapes from the boot under the cuff. A low venous pressure at the foot could be maintained by compressing the foot for 2 seconds every 15 seconds with a pressure which is 10 millimeters of mercury above initial venous pressure. In seated patients with arterial obstruction whose supine ankle blood pressure was 60 milimeters of mercury or less, the rate of blood flow in the skin of the forefoot was increased by 104.1 +/- 43.7 per cent S.E.M., p less than 0.05, during venous pumping. In these patients, a change in posture alone from supine to sitting increased the rate of blood flow by 81.7 +/- 19.47 per cent, p less than 0.002. The combined effect of the erect posture and venous pumping was an increase of 185.7 +/- 49.63 per cent, p less than 0.01. Rest pain was relieved by the combined effect.
Multiphysical finite element modeling of a quartz micro-resonator thermal sensitivity (2015)

A length-extension quartz micro-resonator was developed for time & frequency applications in order to provide an alternative to silicon MEMS resonators for oscillators. Quartz presents two main advantages over silicon: its high intrinsic quality factor and its low thermal sensitivity especially for appropriate quartz cuts. Reference [2] introduces the new micro-resonator and its peculiar structure, focusing on the structural design of the resonator itself to achieve a high quality factor by reducing mounting losses. Its predicted high quality factor frequency product (Q.F) is very close to the state of the art of macro shear mode quartz resonators used in Ultra Stable Oscillators (USOs). This paper focuses on how to achieve a low thermal sensitivity for this resonator. After describing the resonator itself, it focuses on the calculation method to obtain the thermal sensitivity of a resonator with respect to a certain quartz cut. The thermal sensitivity was calculated using the finite element softwares Samcef® and Oofelie® Multiphysics. Those two combined softwares enable us to calculate both thermo-mechanical and piezoelectrical behaviors of the resonator for rotated quartz cuts. At the end of this paper some results are presented to validate the approach on the VIG (Vibrating Integrated Gyro), comparing measurements with Finite Element Modeling (FEM). Eventually the thermal behavior in the extended temperature range (−55°C to 125°C) of four different quartz cuts (the Z cut, the X cut and Z and X rotated cuts) for the new length extension quartz micro-resonator is presented.

Perfusion affects the tissue developmental patterns of human mesenchymal stem cells in 3D scaffolds (2009)

Human mesenchymal stem cells (hMSCs) developed in three-dimensional (3D) scaffolds are significantly affected by culture conditions. We hypothesized that the hydrodynamic forces generated in perfusion bioreactors significantly affected hMSC functionality in 3D scaffolds by shaping the extracellular matrix (ECM) proteins. In this study, hMSCs were grown in 3D poly(ethylene terephthalate) (PET) scaffolds in static and a parallel perfusion system under similar initial conditions for up to 35 days. Results demonstrated that even at very low media velocities (O [10(-4) cm/sec]), perfusion cultures affected the ability of hMSCs to form an organized ECM network as illustrated by the immunostaining of collagen I and laminin fibrous structure. The change in the ECM microenvironment consequently influenced the nuclear shape. The hMSCs grown at the lower surface of static culture displayed a 15.2 times higher nuclear elongation than those at the upper surface, whereas cells grown in the perfusion bioreactor displayed uniform spherical nuclei on both surfaces. The difference in ECM organization and nuclear morphology associated with gene expression and differentiation characteristics of hMSCs. The cells exhibited lower CFU-F colony forming ability and decreased expressions of stem-cell genes of Rex-1 and Oct-4, implying a less primitive stem-cell phenotype was maintained in the perfusion culture relative to the static culture conditions. The significantly higher expression level of osteonectin gene in the perfusion culture at day 28 indicated an upregulation of osteogenic ability of hMSCs. The study highlights the critical role of dynamic culture conditions on 3D hMSC construct development and properties.
5-substituted 4-isoxazoleacetic acids with analgesic activity. (1994)

The synthesis of some 5-substituted 4-isoxazoleacetic acids starting from 5-substituted 4-isoxazolemethanols via their conversion to 4-(bromomethyl)isoxazoles, 4-isoxazoleacetonitriles and acid hydrolysis of the latter is described. 5-Ethyl- and 5-propyl-4-isoxazoleacetic acids showed in the writhing test an analgesic activity comparable to that of aspirin.
Mycoplasma detection-an obligation to scientific accuracy. (1981)

Mycoplasma contamination of cell cultures is, unfortunately, a common occurrence. Because of their extremely small size the contamination is not readily apparent and the presence of mycoplasmas is confirmed by culture on agar. Certain mycoplasmas, most notably Mycoplasma hyorhinis, often do not form colonies on agar due to the presence of toxic components. Other noncultural methods have been devised to detect these "noncultivable" mycoplasmas. A brief overview of these methods will be presented and an attempt made to compare their relative efficiency in detecting microbial contamination in cell cultures.
A 35-ns 64K EEPROM (1985)

An extremely high-speed 8K/spl times/8 EEPROM has been fabricated in a 2-/spl mu/m double-poly CMOS floating gate technology. A typical address and chip enable access time of 35 ns has been achieved. Through a metal option, the device is compatible with 28-pin EEPROM, SRAM, or EPROM, or is a 24 pin bipolar PROM substitute. The high-speed access has been achieved with a fast single-ended sense amplifier, high-speed static bootstrapping techniques, a novel combination of static CMOS and depletion load technology, substrate bias, and high-performance layout. A new column and byte latch circuit implements a page-mode programming feature. Column redundancy implemented with EEPROM fuses increases manufacturability.

Accumulation of protoporphyrin IX in light‐sensitive mutants of <i>Escherichia coli</i> (1992)

The accumulation of protoporphyrin IX (Proto IX) in light-sensitive mutants of Escherichia coli was detected by spectrofluorimetry. Fluorescence emission and excitation spectra were recorded from extracts of bacterial cells. Proto IX clearly accumulated in cells with mutations in the visA (hemH) gene but not in the wild-type strain CA274 or in visA mutants that had been rendered light-resistant by introduction of the wild-type visA+ gene. Accumulation of Proto IX was also not observed in cells with a mutation in the visB gene. These results confirm the hypothesis that the sensitivity of the visA mutants to light is caused by the abnormal accumulation of Proto IX, a substrate of ferrochelatase, as the result of a genetic defect in the gene for ferrochelatase.
Suggesting Songs for Media Creation Using Semantics (2010)

In this paper, we describe a method for matching song lyrics with semantic annotations of picture collections in order to suggest songs that reflect picture content in lyrics or genre. Picture collections are first analyzed to extract a variety of semantic information including scene type, event type, and geospatial information. When aggregated over a picture collection, this semantic information forms a semantic signature of the collection. Typical picture collections in our scenario consist of photo subdirectories in which people store pictures of a place, activity, or event. Picture collections are expected to contain coherent semantic content describing in part or whole the event or activity they depict. The semantic signature of a picture collection is compared against song lyrics using a WordNet expansion based text matching to find songs relevant to the collection. We present interesting song suggestions, compare and contrast scenarios with human versus machine labels, and perform a user study to validate the usefulness of the proposed method. The proposed method will be a useful tool to support user media creation.
The dose dependency of the alpha‐ and beta‐adrenoceptor antagonist activity of carvedilol in man. (1995)

1. The alpha- and beta-adrenoceptor antagonist activity of carvedilol, a beta-adrenoceptor antagonist with vasodilating properties, and labetalol were investigated in 10 healthy male subjects. They received infusions with serially increasing concentrations of isoprenaline and phenylephrine before and after single oral doses of carvedilol 6.25, 12.5 and 25 mg, labetalol 400 mg and placebo at weekly intervals in a double-blind randomised manner. An exercise step test was performed at the end of the infusions. 2. The dose of isoprenaline required to increase heart rate by 25 beats min-1 (I25) and the dose of phenylephrine required to increase systolic and diastolic blood pressure by 20 mm Hg (PS20 and PD20) were calculated using a quadratic fit to individual dose-response curves. Comparisons were made with placebo and P < 0.05 was considered significant. 3. The I25 was increased by carvedilol 25 mg and labetalol 400 mg (P < 0.05). The dose ratios at I25 were: carvedilol 6.25 mg 2.1 +/- 1.6, carvedilol 12.5 mg 3.1 +/- 1.9, carvedilol 25 mg 6.4 +/- 4.9 and labetalol 400 mg 8.8 +/- 4.4. 4. The PS20 was increased by labetalol 400 mg (P < 0.05). The dose ratios at PS20 were: carvedilol 6.25 mg 1.0 +/- 0.2; 12.5 mg, 1.2 +/- 0.2; 25 mg, 1.3 +/- 0.4 and labetalol 400 mg 2.2 +/- 0.8. 5. The PD20 was increased by labetalol 400 mg (P < 0.05). The dose ratios at PD20 were: carvedilol 6.25 mg 1.1 +/- 0.3; 12.5 mg, 1.3 +/- 0.3; carvedilol 25 mg 1.3 +/- 0.4 and labetalol 400 mg 2.1 +/- 0.8.(ABSTRACT TRUNCATED AT 250 WORDS)
A new technique for fabricating cryogenic laser-fusion targets using cold-gas jets (1979)

A new technique of fabricating a uniform layer of solid DT inside a glass microshell has been developed using a heater-wire–cold-gas-jets combination. A D2-filled glass microsphere was continuously cooled by two cold-helium-gas jets, and a controlled amount of current was pulsed through a heater wire surrounding the microshell. This gave rise to fast evaporation and refreezing of the D2 inside the glass shell, resulting in a uniform layer of frozen D2. This new scheme has potential application in the development of a target-fabrication system which would allow for continuous fabrication, inspection, and delivery of cryogenic laser-fusion targets.
Crystallinities of poly(chlorotrifluoroethylene) and its copolymers by differential scanning calorimetry, X‐ray diffraction, and density measurements (1994)

Abstract Crystallinities of films of copolymers of chlorotrifluoroethylene with 0 to 4% vinylidene fluoride, different molecular weights and thermal histories were calculated from differential scanning calorimetry (DSC), X‐ray diffraction (XRD), and density measurements. The crystallinities for these films range between 16 to 58%, 11 to 71%, and 13 to 77% as determined by DSC, XRD, and density, respectively. Although the numerical value of the DSC, XRD, and density crystallinities obtained by each of the techniques are different, they correlate well with each other. The primary source of error in DSC is the uncertainty in drawing the baseline for separating the heat of fusion and heat of crystallization. In XRD, the ambiguities in the separation of the amorphous and crystalline peaks reduce the precision of the results. Calculation of crystallinity from density values requires that the distribution of the VF 2 between the amorphous and crystalline regions be known. In addition, the density technique is not sensitive to variations in the crystalline and amorphous densities.
Calvarial Bone Repair with Porous D,L‐Polylactide (1995)

Bone is a storehouse of biologic factors enabling it to regenerate without scar formation. Recombinant technology has made many of these factors available in significant quantity for therapeutic applications. However, a system to deliver recombinant bone-regenerating factors is needed. Biodegradable, biocompatible polymers have shown promise for delivering bone regenerative factors, such as bone morphogenetic protein. The polymer we selected to investigate was racemic D,L-polylactide. Our immediate objective was to engineer porous D,L-polylactide to promote bone ingrowth (osteoconduction). We tested the hypothesis that porous D,L-polylactide implanted in a standard intraosseous calvarial wound would not hinder but would support bone regeneration. Therefore porous polylactide disks (65% void volume) were manufactured with pores < or = 100 microns, < or = 200 microns, and < or = 350 microns; implanted in rabbits' calvariae, and retrieved 1, 2, 4, and 6 months after insertion. Quantitative histomorphometry revealed a possible relationship in the amount of bone ingrowth with increasing pore size over time. The D,L-polylactide disks < or = 350 microns had the greatest quantity of bone ingrowth (< or = 0.05). However, a disturbing finding was the multinucleated giant cell response associated with all implanted disks. We speculate these cells may have produced an inhospitable environment stifling osteoconduction. Consequently, postsynthesis engineering refinements of D,L-polylactide to eliminate the giant cell response are crucial before loading with bone morphogenetic protein.
