Plasma etching of Cr photomasks: parametric comparisons of plasma sources and process conditions (1997)

As device design rules continue to shrink, on-mask Cr structures must experience a corresponding reduction in size. Although 0.25 micrometer design rules require only 1 micrometer Cr features, the use of OPC structures, which may be needed to minimize line foreshortening and corner rounding, necessitate features to be etched into the Cr which are significantly smaller than this. This need, coupled with the demand for reduced CD bias and improved CD uniformities, requires the use of an alternate chrome etch technology. Plasma etching of Cr can be highly anisotropic, greatly reducing the etch under cut which is responsible for the CD bias typically associated with wet etching. Reactive ion etching (RIE) can provide significant enhancements in the capability of replicating micron and sub-micron features, but the Cr etch rate non-uniformity which is typical of this technique can translate into a CD nonuniformity. This is due in part to the relatively high pressure of operation (50 - 100 mTorr which is necessary to reduce the self generated dc voltage And which minimizes the photo resist etch rate. Recently, high density plasma sources, such as inductively coupled plasma (ICP), have become available which have the ability to operate both at low pressures and high plasma density while maintaining a low and controllable dc voltage. The low pressure operation significantly improves the etch rate uniformity and consequently the CD uniformity. In this study a design of experiment (DOE) is used to investigate the parameter space associated with the dry etching of Cr using an ICP source. The responses of Cr etch rate, selectivity to photo resist, CD uniformity and mean CD to target are studied, and from this an optimized parameter space is defined. Within this space the effect of overetch, dc voltage and pattern loading on the CD uniformity are also investigated. The role played by the photo resist profile in determining the Cr etch profile is also studied and preliminary measurements are made to understand the effect of the above parameters on the mask CD bias.
A method for word sense disambiguation of unrestricted text (1999)

Selecting the most appropriate sense for an ambiguous word in a sentence is a central problem in Natural Language Processing. In this paper, we present a method that attempts to disambiguate all the nouns, verbs, adverbs and adjectives in a text, using the senses provided in WordNet. The senses are ranked using two sources of information: (1) the Internet for gathering statistics for word-word cooccurrences and (2) WordNet for measuring the semantic density for a pair of words. We report an average accuracy of 80% for the first ranked sense, and 91% for the first two ranked senses. Extensions of this method for larger windows of more than two words are considered.
A magnetic coupling without parasitic force for measuring devices (1994)

Original structures of permanent magnet couplings have been studied. They can transmit a torque without creating forces or stiffnesses between the driver and the driven part. Except for torque, the two parts are in indifferent equilibrium. These couplings have been designed for measuring devices in which they exert no force on the bearings but they can be used in other domains.
Elastic Moduli of 2D Grafted Tethered Membranes (1995)

In order to simulate the elastic behaviour of 2D gels, we introduce a tethered model. Both excluded volume and topological constraints are taken into account. When the gel is grafted on a surface, removing cross-links transforms the grid into a polymer brush. The Monte Carlo study of elastic moduli proves that the brush, a less constrained system, has a greater shear modulus than the grid. This apparent paradox shows the influence of thermal fluctuations that reveals correlations of “blocks" inside these structures.

Narrowband Interference Suppression in UWB Impulse Radar for Human Being Detection (2007)

Narrowband interference (NBI) is a major source of performance degradation in human being detection applications using impulse radar and stroboscopic samplers. Implementation of notch filters results in undesired ringing of the target response. Four methods are developed and their performance analysed: two variations of the approach that extracts the NBI and subtracts its contribution and two variations of the approach that filters the NBI out and restores the missing spectrum. NBI is modelled as modified GSM signal. It is shown that latter methods perform better both in terms of NBI suppression, but also in terms of signal waveform and energy preservation.
Multisensor Data Fusion for Additive Manufacturing Process Control (2018)

Achieving cutting-edge mechanical properties of metal parts realized by additive manufacturing (AM) demands articulated process control strategies, due to the multitude of physical phenomena involved in this kind of manufacturing processes. Complexity is even higher for what concerns the direct energy deposition (DED) technique, which offers much more potential flexibility and efficiency with respect to other metal AM technologies, at the cost of more difficult process control. The present work presents a multisensor approach able to combine online signals, collected while monitoring the deposition process, and data coming from offline inspection devices, during the built part quality check phase. This data fusion approach constitutes the foundation for the process modeling phase and, consequently, for the implementation of an intelligent control strategy that would act online by adjusting the machine process parameters chasing part dimensional, mechanical, and quality targets. The benefits of the proposed solution are assessed through a dedicated experimental campaign on a DED machine.
Design phase transitions in object-oriented modeling of architecture (2002)

The project IDEA+ aims to develop an ÂIntegrated Design Environment for ArchitectureÂ. Its goal is providing a tool for the designer-architect that can be of assistance in the early-design phases. It should provide the possibility to perform tests (like heat or cost calculations) and simple simulations in the different (early) design phases, without the need for a fully detailed design or remodeling in a different application. The test for daylighting is already in development (Geebelen, to be published). The conceptual foundation for this design environment has been laid out in a scheme in which different design phases and scales are defined, together with appropriate tests at the different levels (Neuckermans, 1992). It is a translation of the ÂdesignerlyÂ way of thinking of the architect (Cross, 1982). This conceptual model has been translated into a ÂCore Object ModelÂ (Hendricx, 2000), which defines a structured object model to describe the necessary building model. These developments form the theoretical basis for the implementation of IDEA+ (both the data structure & prototype software), which is currently in progress. The research project addresses some issues, which are at the forefront of the architectÂs interest while designing with CAAD. These are treated from the point of view of a practicing architect.
Lack of clinical and physiological relationship between gastrin and calcitonin in man (1981)

The clinical and physiological relevance of the relationship between gastrin and calcitonin has been investigated in normal subjects and in patients suffering from gastritis or duodenal ulcer. Basal plasma levels of calcitonin are increased in these patients but there is no significant relationship between calcitonin and gastrin levels. Acute pentagastrin injection in normal male subjects increased significantly (P less than 0.05) plasma calcitonin levels whereas lower doses of pentagastrin which are known to stimulate gastric secretion are without effect on calcitonin levels. Moreover, stimulation of gastrin secretion by a protein test meal and by intragastric administration of a calcium chloride solution is not followed by any significant increase of plasma calcitonin levels. These results suggest that the stimulation of calcitonin secretion by gastrin and its synthetic analogue pentagastrin is a pharmacological rather than a physiological phenomenon.
Report A, chemical oceanographic data from the Persian Gulf and Gulf of Oman (1978)

During February and March of 1977 a major geochemical, biological and geophysical survey of the Persian Gulf and adjacent waters was carried out on R/V ATLANTIS II, Cruise 93, Legs 17 and 18. It is the purpose of this report to present the chemical oceanographic data obtained, together with a documentation of the analytical techniques and a simple discussion of the major features observed. Of the 54 hydrographic stations (ATLANTIS II, Stations 2357-2410) occupied during Leg 17, 45 may be said to be in the Persian Gulf proper, the remainder being in the Gulf of Oman and the northwestern Arabian Sea.

Optimization of on-chip micro-electromagnets for biomolecular separation (2003)

This work deals with the design of on-chip planar electromagnets that will be introduced into a microfluidic device as part of a DNA extraction system. Different geometries of planar electromagnets have been designed, fabricated and tested using SQUID, and a comparison between their magnetic fields is made. The magnetic fields generated by different electromagnets were also studied using both theoretical considerations and FEA (Finite Element Analysis) simulations. The analysis and results of SQUID measurements and magnetic field simulation related to the magnetic bead-cell composite separation ability will also be presented.
Natural compounds isolated from the Indonesian plant, Artocarpus communis, inhibit 5-lipoxygenase of cultured mastocytoma cells. (1988)

One of five compounds, AC-5-1, strongly inhibits 5-lipoxygenase with a half-inhibition dose of 5±0.12×10-8M. However, prostaglandin synthesizing activity is not inhibited until 10-5M. AC-5-1 is a highly selective inhibitor for 5-lipoxygenase. The AC-5-1 at 10-5M inhibits 96% of leukotriene C4 synthesis of mouse peritoneal cells facilitated by calcium-ionophore. Arachidonic acid induced ear edema of mice, an in vivo inflammatory model, involving leukotriene induction, is strongly inhibited by AC-5-1 in a dose-dependent manner. The inhibition is the strongest of any inhibitors of 5-lipoxygenase reported previously. Since the natural compound AC-5-1 can selectively inhibit 5-lipoxygenase and affect in vivo inflammation, it will be interesting to investigate the role of leukotrienes on inflammation and other physiological processes.
Surface Modification of ZnO Layers via Hydrogen Plasma Treatment for Efficient Inverted Polymer Solar Cells (2015)

Modifications of the ZnO electron extraction layer with low-pressure H plasma treatment increased the efficiency of inverted polymer solar cells (PSCs) based on four different photoactive blends, namely, poly(3-hexylthiophene):[6,6]-phenyl C71 butyric acid methyl ester (P3HT:PC71BM), P3HT:1',1″,4',4″-tetrahydro-di[1,4]methanonaphthaleno-[5,6]ullerene-C60 (P3HT:IC60BA), poly[(9-(1-octylnonyl)-9H-carbazole-2,7-diyl)-2,5-thiophenediyl-2,1,3-benzothiadiazole-4,7-diyl-2,5-thiophenediyl]:PC71BM (PCDTBT:PC71BM), and (poly[[4,8-bis[(2-ethylhexyl)oxy]benzo[1,2-b:4,5-b']dithiophene-2,6-diyl][3-fluoro-2-(2-ethylhexy)carbonyl]thieno[3,4-b]thiophenediyl]]):PC71BM (PTB7:PC71BM), irrespective of the donor:acceptor combination in the photoactive blend. The drastic improvement in device efficiency is dominantly attributable to the reduction in the work function of ZnO followed by a decreased energy barrier for electron extraction from fullerene acceptor. In addition, reduced recombination losses and improved nanomorphology of the photoactive blend in the devices with the H plasma treated ZnO layer were observed, whereas exciton dissociation also improved with hydrogen treatment. As a result, the inverted PSC consisting of the P3HT:PC71BM blend exhibited a high power conversion efficiency (PCE) of 4.4%, the one consisting of the P3HT:IC60BA blend exhibited a PCE of 6.6%, and our champion devices with the PCDTBT:PC71BM and PTB7:PC71BM blends reached high PCEs of 7.4 and 8.0%, respectively.
NEW READOUT TECHNIQUE USING DOMAIN COLLAPSE ON MAGNETIC MULTILAYER (1995)

In the magnetically induced super resolution, a rapid change in the readout signal was observed. The rapid change is explained by a domain collapse model. We proposed a new readout technique which utilizes the rapid change in the signal. The technique can reduce the readout jitters and enables high signal to noise ratio detection. Combination of mark position recording and a write-read channel with small detection window enables the high density recording of 0.5 μm/bit or less even if the carrier to noise ratio of the disk is not sufficiently high.

High Sensitive and Efficient Holographic Grating Generation in Functionalized Polymer-Dissolved Liquid Crystal Composites (2001)

Abstract High sensitive and efficient holographic gratings were generated in functionalized polymer-dissolved liquid crystal composites. The gratings originate in the photorefractive-like space charge filed and resultant periodic reorientation of liquid crystal molecules. The demonstration for edge-enhancement of two-dimensional optical images was performed by using the developed materials. Key Words: photorefractive effectliquid crystalhologramedge-enhancementpolymer
Studies on peptides. CLVII. Synthesis of a frog-skin peptide, sauvagine. (1988)

A tetracontapeptide corresponding to the entire amino acid sequence of a frog skin peptide, sauvagine, was synthesized by assembling eight peptide fragments of established purity followed by deprotection with 1 M trimethylsilyl trifluoromethanesulfonate-thioanisole in trifluoroacetic acid. The synthetic peptide stimulated secretion of immunoreactive corticotropin from rat pituitary cells and its potency was estimated to be equivalent to that of synthetic ovine corticotropin releasing factor. Synthetic sauvagine displayed long-lasting hypotensive action in rats.
Synthesis of networks of custom processing elements for real-time physical system emulation (2013)

Emulating a physical system in real-time or faster has numerous applications in cyber-physical system design and deployment. For example, testing of a cyber-device's software (e.g., a medical ventilator) can be done via interaction with a real-time digital emulation of the target physical system (e.g., a human's respiratory system). Physical system emulation typically involves iteratively solving thousands of ordinary differential equations (ODEs) that model the physical system. We describe an approach that creates custom processing elements (PEs) specialized to the ODEs of a particular model while maintaining some programmability, targeting implementation on field-programmable gate arrays (FPGAs). We detail the PE micro-architecture and accompanying automated compilation and synthesis techniques. Furthermore, we describe our efforts to use a high-level synthesis approach that incorporates regularity extraction techniques as an alternative FPGA-based solution, and also describe an approach using graphics processing units (GPUs). We perform experiments with five models: a Weibel lung model, a Lutchen lung model, an atrial heart model, a neuron model, and a wave model; each model consists of several thousand ODEs and targets a Xilinx Virtex 6 FPGA. Results of the experiments show that the custom PE approach achieves 4X-9X speedups (average 6.7X) versus our previous general ODE-solver PE approach, and 7X-10X speedups (average 8.7X) versus high-level synthesis, while using approximately the same or fewer FPGA resources. Furthermore, the approach achieves speedups of 18X-32X (average 26X) versus an Nvidia GTX 460 GPU, and average speedups of more than 100X compared to a six-core TI DSP processor or a four-core ARM processor, and 24X versus an Intel I7 quad core processor running at 3.06 GHz. While an FPGA implementation costs about 3X-5X more than the non-FPGA approaches, a speedup/dollar analysis shows 10X improvement versus the next best approach, with the trend of decreasing FPGA costs improving speedup/dollar in the future.
Comparison of Excretion of Bromsulphthalein and Sodium Cholate after Intravenous Injection, Separately and Combined (1951)

1. A modification of Minibeck's method was found to be satisfactory for the determination of cholic acid and glycocholic acid added to serum. 2. In healthy dogs when bromsulphthalein and sodium cholate were injected together, the concentration of bromsulphthalein in the serum was greatly elevated five and fifteen minutes after administration. The cholate concentration, however, was normal. 3. In early central necrosis of the liver produced by carbon tetrachloride, the bromsulphthalein excretion was definitely delayed while the cholate excretion was only slightly changed. The bromsulphthalein test appeared to be more sensitive in detecting early hepatic damage. During the first thirty minutes the bromsulphthalein retention in the combined test paralleled roughly the retention when bromsulphthalein was given alone, but was 35-60% higher.
Formation of Smooth Muscle Alpha Actin Filaments in CD34+ Bone Marrow Cells in Elastic Lamina‐Containing Matrix (2006)

Circulating bone marrow cells contribute to the regeneration of vascular smooth muscle (SM)‐like cells in arterial injury, a process implicated in atherogenesis. In this report, we show that CD34+ bone marrow cells are a source for regenerating SM‐like cells, exposure to elastic laminae enhances the formation of SM alpha actin filaments in CD34+ cells, and SH2 domain‐containing protein tyrosine phosphatase (SHP)‐1 mediates the effect of elastic laminae on the formation of SM alpha actin filaments. Examination by immunohistochemistry demonstrated that the mouse bone marrow contains cells that express SM alpha actin (2+/−0.9%). Almost all SM alpha actin+ bone marrow cells co‐express CD34, while 88 +/− 16% CD34+ bone marrow cells co‐express SM alpha actin. When cultured on elastic laminae, a fraction of CD34+ cells formed SM alpha actin filaments (35+/−9% at day 20). However, the formation of SM alpha actin filaments was significantly reduced on collagen‐containing adventitia (9+/−6% at day 20). The interaction of CD34+ cells with elastic laminae induced an apparent increase in the relative phosphorylation of SHP‐1. In contrast, exposure to adventitia did not cause significant SHP‐1 phosphorylation. Transfection with a SHP‐1‐specific siRNA cloning vector induced a significant decrease in the formation of SM alpha actin filaments in CD34+ cells on elastic laminae (from 35+/−9% to 11+/−7%). These observations suggest that CD34+SM alpha actin+ bone marrow cells are a potential source for the regeneration of SM‐like cells, elastic laminae stimulate the formation of SM alpha actin filaments in CD34+ bone marrow cells, and SHP‐1 mediates the formation of SM alpha actin filaments.

Exploring the Role of p97 and Its UBX-Domain Cofactors Through Identification of Their Interacting Proteins (2012)

The elucidation of protein–protein interaction networks can provide preliminary insights into the function of uncharacterized proteins based on the interactions they establish in the cell. Here, we describe a protein immunoprecipitation protocol that can be used in combination with mass spectrometry analysis to identify the p97 interactome as well as specific subgroups of proteins interacting with its UBX-domain adaptors. This approach aims to dissect the role played by individual UBX cofactors within the complex array of cellular functions performed by p97.
Data Integration Via Universal Keys (2006)

We describe an infrastructure for integrating distributed data called DataSpace [3] In addition to supporting data and metadata, the infrastructure also supports globally unique keys for integrating data that we call universal keys. In contrast to some of the standard approaches to data integration, DataSpace does not try to achieve the full semantic integration of distributed data, but instead provides the minimum infrastructure necessary to integrate distributed data that is attached to universal keys. We also describe some applications that have been built with this infrastructure in astronomy, bioinformatics, and earth science. TCP-based web and grid services, as usually deployed, have been shown to have problems for integrating very large data sets over wide area, high performance networks [1]. Recently, we have implemented a peer-to-peer version of DataSpace called Sector that is designed for working with large data sets over wide area, high performance networks [7]. Sector has been used to distributed the terabyte size catalog data for the Sloan Digital Sky Survey (SDSS) from Chicago to locations in the U.S., Europe and Asia. This paper is based in part on [2]
