Ultra lightweight structures for deployed optics (2002)

Future space missions, such as acquisition of high-resolution images in visible or near-visible wavelengths for space surveillance, target identification, and astronomy, require the deployment of space-based telescopes with large (greater than 4 m) effective apertures and with surface accuracy of better than 0.1 micron RMS. Current systems are limited not only by the physical size of the launch vehicle shroud, but also by the quality and alignment of the system after incurring stresses induced by launch. A large, lightweight, durable space telescope using precision deployable structures offers the potential for breakthroughs in high-resolution image acquisition. The Air Force Research Laboratory Space Vehicle Technologies Division, in conjunction with Aeronautical and Astronautical Engineering Department at Stanford University, has been doing research into a new structural configuration fabricated using the newly developed Tooling Reinforced Grid (TRIG) process. These innovative lightweight TRIG structures are extremely stiff and easy to manufacture. Additionally, TRIG structures can be several times lighter than traditional composite structures for stiffness-controlled applications. The first full-scale TRIG structure, with accompanying deployment structure/hardware, was recently fabricated as part of a precision-deployed optical boom experiment. The objective of this experiment was to study deployment accuracy and stability. In this paper, an overview of this experiment is presented from a deployment and structural point of view.
Linear algorithms for optimizing the layout of dynamic CMOS cells (1988)

In many CMOS design styles the basic building blocks are complex (static or dynamic) CMOS gates with up to a few dozen transistors. The layout optimization for such gates takes the shape of graph optimization problems. Two such graph problems, corresponding to different layout styles for basic cells composed of dynamic CMOS gates, are considered. Both problems are solved in linear time; the number of gates in the cell is considered.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">&gt;</ETX>
VLSI implementation of routing tables: tries and CAMs (1991)

Routing tables for communication networks can be designed using many different approaches, including table lookup, content-addressable memory (CAM), hashing, and tries. The authors compare these approaches in the context of custom VLSI implementation. For tables with a small number of entries and a large address space, CAMs can be very cost effective. If only RAM is available, it is shown that tries, of which simple table lookup is a special case, provide a useful architecture. Also considered is a new variation, table partitioning, which constitutes a useful compromise between the conventional CAM and a trie.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">&gt;</ETX>
Accelerated Integral Equation Solution Methods on Clusters and Multicore Processors Session Name: Algorithm and Techniques for Parallel Processing for EMI/EMC (2007)

Boundary element based methods are now prevalent as analysis methods for large-scale microelectronic circuits. With the advent of fast multilevel techniques, these are comparable to and often surpass PDE-based solutions. The next challenge is to ensure these algorithms are scaleable on multi-core machines and parallel clusters. This paper discusses the parallelization of multilevel low-rank based algorithms for fast boundary element solvers applied to microelectronics.
Présidentielle 2017 : l’analyse des tweets renseigne sur les recompositions politiques (2017)

Voici un exemple d’utilisation de Big Data pour observer la société. C’est d’analyse politique qu’il s’agit ici. Les auteurs tirent parti des tweets émis juste avant et juste après le premier tour de l’élection présidentielle française d’avril 2017 pour regrouper les comptes twitter, en tenant compte à la fois des contenus des messages et des liens entre ces comptes. Ayant attribué des noms de partis politiques aux groupes issus de leur travail, ils peuvent proposer une analyse des forces en présence avant et après l’élection, ainsi que des transferts entre ces forces. Les détenteurs d’un compte twitter ne forment certainement pas un échantillon représentatif de toute la population électorale : et pourtant les résultats sont remarquablement proches de ceux de l’élection.
Understanding tunneling magnetoresistance during thermal annealing in MgO-based junctions with CoFeB electrodes (2010)

The competition between the interface crystallization and diffusion processes, their influence on the onset of symmetry-filtering coherent tunneling of ${\ensuremath{\Delta}}_{1}$ band electrons in the MgO-based magnetic tunnel junctions is investigated. Systematic study of the transport and magnetoresistance during thermal annealing of these junctions shows a unique behavior of the tunneling conductance in the parallel state. The optimal annealing time for achieving giant tunneling magnetoresistance at different temperatures is determined. The evolution of magnetoresistance consists of three distinct regions, responsible by different contributions from CoFeB electrodes and the MgO barrier. The whole phenomenon can be understood through an empirical model based on the Landauer tunneling picture.
Single Technique for Simultaneous Monitoring of OSNR and Chromatic Dispersion at 4OGbit/s (2006)

A novel single technique for simultaneous OSNR and chromatic dispersion monitoring is proposed. It is used for dynamically-reconfigurable 4OGbit/s systems where the monitoring and compensation are done on a per-burst basis.
Pathogenic role of ganglioside metabolism in neurodegenerative diseases (2014)

Ganglioside metabolism is altered in several neurodegenerative diseases, and this may participate in several events related to the pathogenesis of these diseases. Most changes occur in specific areas of the brain and their distinct membrane microdomains or lipid rafts. Antiganglioside antibodies may be involved in dysfunction of the blood-brain barrier and disease progression in these diseases. In lipid rafts, interactions of glycosphingolipids, including ganglioside, with proteins may be responsible for the misfolding events that cause the fibril and/or aggregate processing of disease-specific proteins, such as α-synuclein, in Parkinson's disease, huntingtin protein in Huntington's disease, and copper-zinc superoxide dismutase in amyotrophic lateral sclerosis. Targeting ganglioside metabolism may represent an underexploited opportunity to design novel therapeutic strategies for neurodegeneration in these diseases.
Effect of low glycemic index food and postprandial exercise on blood glucose level, oxidative stress and antioxidant capacity (2015)

Low glycemic index (GI) food and postprandial exercise are non-drug therapies for improving postprandial hyperglycemia. The present randomized, crossover study investigated the effect of low GI food combined with postprandial exercise on postprandial blood glucose level, oxidative stress and antioxidant capacity. A total of 13 healthy subjects were each used in four experiments: i) rice only (control), ii) salad prior to rice (LGI), iii) exercise following rice (EX) and iv) salad prior to rice and exercise following rice (MIX). The blood glucose level, oxidative stress and antioxidant capacity were then measured. At 60 min after the meal, the blood glucose level was observed to be increased in the MIX group compared with that in the LGI group. Furthermore, at 180 min, the antioxidant capacity was found to be reduced in the MIX group compared with those of the LGI and EX groups. These findings suggest that low GI food combined with postprandial exercise does not improve postprandial hyperglycemia. It may be necessary to establish optimal timing and intensity when combining low GI food with postprandial exercise to improve postprandial hyperglycemia.
Observation of the B s 0  → J/ψK S 0 K ± π ∓ decay (2014)

Decays of the form B 0 (s) J/ K 0 S h + h ( )-(h ( ) = K, ) are searched for in proton-proton collision data corresponding to an integrated luminosity of 1.0 fb -1 recorded with the LHCb detector. The first observation of the B 0 s J/ K 0 S K decay is reported, with significance in excess of 10 standard deviations. The B 0 J/ K 0 S K + K -decay is also observed for the first time. The branching fraction of B 0 J/ K 0 S + -is determined, to significantly better precision than previous measurements, using B 0 J/ K 0 S as a normalisation channel. Branching fractions and upper limits of the other B 0 (s) J/ K 0 S h + h ( )- modes are determined relative to that of the B 0 J/ K 0 S + -decay.
I. Vinylation of Cotton Slivers and Print Cloth (1965)

Cotton cellulose in the form of slivers and print cloth was successfully vinylated with acetylene without destroying the fiber structure. D.S. (degree of substitution) values up to 0.70 were achieved in vinylation reactions at 120° C, using potassium hydroxide as the catalyst. The important variables in the vinylation reaction were found to be the catalyst and its concentration, the moisture content of the catalyst-impregnated cotton, solvent, acetylene pressure, time, and temperature. The weight of vinylated cotton re covered was 95% to 100% of the weight of the cotton used in the case of the best vinylation conditions, and the vinylated cotton showed good storage stability.
A spin-on photosensitive polymeric etch protection mask for anisotropic wet etching of silicon (2008)

Newly developed photosensitive etch protection materials have key advantages over standard photoresists typically used in today's MEMS applications. Using these new materials eliminates the need for silicon nitride (SiN) masks deposited via CVD processes, which require significant investments in processing equipment, utilize extreme processing conditions and contribute to an overall decrease in throughput. This new technology will enhance throughput by reducing the number of process steps and simplify the process flow with minimal impact on overall undercut performance. The polymeric coating serves as a SiN mask replacement for etching silicon substrates in alkaline anisotropic etchants such as KOH and TMAH. The undercut performance observed is larger than that of SiN when etched in KOH, but when alternative alkaline etchants such as TMAH are used, the undercut is identical (1–2% with respect to etch depth). Various factors, such as primer bake, topcoat final cure temperature, etchant concentration and substrate surface conditions, have all been shown to affect undercut results. An additional advantage of this new technology is that it can be easily reworked/removed by solvents, plasma etch, Nano-Strip®, Piranha and RCA cleaning solutions depending on where the removal takes place in the process.
Genome Sequence of Sporolactobacillus terrae DSM 11697, the Type Strain of the Species (2014)

Sporolactobacillus terrae DSM 11697 is the type strain of S. terrae. Here, we present a 3.2-Mb assembly of its genome sequence. As S. terrae is one of the important lactic acid bacteria, the genome sequence may provide insights into the molecular mechanism for its further microbial investigation.
Photosynthetic capacity is related to the cellular and subcellular partitioning of Na+, K+ and Cl‐ in salt‐affected barley and durum wheat (2006)

The capacity of plants to tolerate high levels of salinity depends on the ability to exclude salt from the shoot, or to tolerate high concentrations of salt in the leaf (tissue tolerance). It is widely held that a major component of tissue tolerance is the capacity to compartmentalize salt into safe storage places such as vacuoles. This mechanism would avoid toxic effects of salt on photosynthesis and other key metabolic processes. To test this, the relationship between photosynthetic capacity and the cellular and subcellular distribution of Na+, K+ and Cl- was studied in salt-sensitive durum wheat (cv. Wollaroi) and salt-tolerant barley (cv. Franklin) seedlings grown in a range of salinity treatments. Photosynthetic capacity parameters (Vcmax, Jmax) of salt-stressed Wollaroi decreased at a lower leaf Na+ concentration than in Franklin. Vacuolar concentrations of Na+, K+ and Cl- in mesophyll and epidermal cells were measured using cryo-scanning electron microscopy (SEM) X-ray microanalysis. In both species, the vacuolar Na+ concentration was similar in mesophyll and epidermal cells, whereas K+ was at higher concentrations in the mesophyll, and Cl- higher in the epidermis. The calculated cytoplasmic Na+ concentration increased to higher concentrations with increasing bulk leaf Na+ concentration in Wollaroi compared to Franklin. Vacuolar K+ concentration was lower in the epidermal cells of Franklin than Wollaroi, resulting in higher cytoplasmic K+ concentrations and a higher K+ : Na+ ratio. This study indicated that the maintenance of photosynthetic capacity (and the resulting greater salt tolerance) at higher leaf Na+ levels of barley compared to durum wheat was associated with the maintenance of higher K+, lower Na+ and the resulting higher K+ : Na+ in the cytoplasm of mesophyll cells of barley.

A transferable non‐destructive method for the quantification of coronary stent coating components using Raman spectroscopy (2015)

Drug content of coronary stents is destructively evaluated using high pressure liquid chromatography. The method involves the dissolution of the coating from the stent into a solution and the analysis and quantification of the solvents' drug content. Quantification of the components of drug by Raman has been demonstrated with most recent methods using multivariate techniques. However, the calibration models generated as part of these methods are not easily transferable because they are developed using defined mixtures. In this work, we demonstrate a transferable non‐destructive Raman method for the evaluation and quantification of the drug coating components by developing a model from the pure samples of the coating constituents. Using the designed experiment, the transferable Raman method is equivalence tested with the standard high pressure liquid chromatography approach and compares favorably as a non‐destructive viable alternative. A method of dealing with the microheterogeneity of stent coatings is presented by spectral sample collection through the rotation of the stent. Knowledge of the coating formation and substrates is required in order to correctly interpret the results. Copyright © 2015 John Wiley &amp; Sons, Ltd.

Compression Molding Mechanism and Parameter Evaluation of SiP (2020)

As microelectronic market grows, the complexity and the functionality of semiconductors push the manufacture ability to evolve. On the leading edge of trend, such as high speed computing, wearable device, cloud, IoT, AiP and 5G all require a better solution for higher performance and power efficiency semiconductor packages. To meet the market demands, system in package (SiP) technology rises as having advantages of integration flexibility, smaller form factor, better electrical performance and faster time to market.Molded underfill (MUF) is highly applied process when it comes to SiP assembly process. Compression molding comes as an appealing process with more uniform flow and low mold bleed. In this paper, we developed a pre-evaluation rule to assess voids risk of compression molding process by simulation. In order to achieve our goal, we chose a bunch of different SiP type packages and performed a serious of DoEs. DoEs are decided by manipulating chosen indicators. All simulations are done with Moldex3D software.We analyzed voids and packages relation and came up with several factors which we think have significant influence on void forming. Under passive components there's solder paste, the narrow gap between two strips of solder paste is where void usually locate. We discovered that, when gap height lower than 40um and gap length larger than 1.6mm, there's high risk of void forming. On the other hand, voids also tend to between bumps under chips. Our indicator here is the area ratio of bump and chip, represent the dense level of bumps. When area ratio is large than 0.3, high risk of void forming is decided. From these conclusions we drew, a preevaluation rule is developed, meanwhile getting a closer look of void forming mechanism.
Insect immunity. Isolation from a coleopteran insect of a novel inducible antibacterial peptide and of new members of the insect defensin family. (1991)

Injection of heat-killed bacteria into larvae of the large tenebrionid beetle Zophobas atratus (Insecta, Endopterygota, Coleoptera) results in the appearance in the hemolymph of a potent antibacterial activity as evidenced by a plate growth inhibition assay. We have isolated three peptides (A-C) from this immune hemolymph which probably account for most of this activity. Their primary structures were established by a combination of peptide sequencing and molecular mass determination by mass spectrometry. Peptide A, which is bactericidal against Gram-negative cells, is a 74-residue glycine-rich molecule with no sequence homology to known peptides. We propose the name coleoptericin for this novel inducible antibacterial peptide. Peptides B and C are isoforms of a 43-residue peptide which contains 6 cysteines and shows significant sequence homology to insect defensins, initially reported from dipteran insects. This peptide is active against Gram-positive bacteria. The results are discussed in connection with recent studies on inducible antibacterial peptides present in the three other major orders of the endopterygote clade of insects: the Lepidoptera, Diptera, and Hymenoptera.

Technological indicators of nanocellulose advances obtained from data and text mining applied to patent documents (2014)

Nanocellulose is remarkable cellulose-based nanomaterials that have a potential for innovation and sustainable appeal. Their advances can be assessed using patent indicators and text mining techniques. The aim of this study was at analyzing the advances in nanocellulose based on indicators compiled from patents filed at the United States Patent and Trademark Office (USPTO) from 2000 to 2012. Assignees, technological subjects, highly cited patents, applications and types of nanocellulose were obtained by mining structured and unstructured data. The results highlighted the different interests in the USA market, mainly after 2007. Mined terms from titles and abstracts could add further information to the analysis. However, although the method applied was useful, it was not sufficient to identify all applications and types of nanocellulose involved in the sample analyzed, therefore it is recommended that other document parts be included in future analyses.
