Devices Based on Co-Integrated MEMS Actuators and Optical Waveguide: A Review (2016)

The convergence of Micro Electro Mechanical Systems (MEMS) and optics was, at the end of the last century, a fertile ground for a new breed of technological and scientific achievements. The weightlessness of light has been identified very early as a key advantage for micro-actuator application, giving rise to optical free-space MEMS devices. In parallel to these developments, the past 20 years saw the emergence of a less pursued approach relying on guided optical wave, where, pushed by the similarities in fabrication process, researchers explored the possibilities offered by merging integrated optics and MEMS technology. The interest of using guided waves is well known (absence of diffraction, tight light confinement, small size, compatibility with fiber optics) but it was less clear how they could be harnessed with MEMS technology. Actually, it is possible to use MEMS actuators for modifying waveguide properties (length, direction, index of refraction) or for coupling light between waveguide, enabling many new devices for optical telecommunication, astronomy or sensing. With the recent expansion to nanophotonics and optomechanics, it seems that this field still holds a lot of promises.
Edge and region image segmentation processes on the parallel vision machine: Transvision (2002)

The authors present a method of setting up image processing chains for applications with strict temporal constraints. The method is based on the concept of a modular parallel vision machine, also called an evaluation machine. Starting from this concept, the authors define the most suitable target machine for helping with a real time application. This evaluation machine, which is called Transvision, is based on two operation models: the first, of pipeline type, is based on real time video models and deals with a certain amount of low level processings. The second, of MIMD distributed memory type, is based on the transputer. It deals with low, medium and high level algorithms. A modular bridge called a video node makes exchange and control possible between the two worlds. The procedure is described for two examples of image segmentation chains; one of them is the contour type and the other the region type. The authors present parallelization schemes and the temporal performances obtained for each of the chains.

Fundamental Aspects of Rubber Adhesion to Brass-Plated Steel Tire Cords (1979)

Abstract During the past several years the fundamental knowledge of the processes which lead to rubber-brass bond formation and to bond degradation has increased considerably. As a result of the application of new instrumental techniques to the study of the rubber-brass interface it has been established that the brass surface is chemically attacked under formation of Cu x S , ZnS, and ZnO. These products become an integral part of the rubber-to-metal bond. It has unequivocally been demonstrated that excessive or insufficient formation both lead to a low rubber-brass bond strength. The theories put forward by Buchan in the early forties (culminating in the only monograph on the subject thus far) have thus been proven to be largely correct. The rubber-brass bond can be interpreted as an adhesion of sulfur crosslinks to a sulfidized brass surface. These crosslinks are not necessarily bonded to the surface by fully developed “chemical” bonds, but should rather be interpreted as covalent bonds, comparable to those formed by copper oxide or copper sulfide and various organic complexing molecules containing electron-donating nitrogen or sulfur atoms. In spite of the relatively weak bonds between sulfur crosslinks and sulfidized brass surfaces, the adhesion between rubber and brass exceeds the rubber tear strength, since there is a very intimate contact between rubber and sulfide film which actually grows into the polymer. As a result, the contact area of the two phases is significantly enlarged. There is evidence that only certain types of crosslinks, probably the poly-sulfides, give rise to a high bond strength, possibly because of steric reasons. Best results have been obtained if the brass surface consist completely of cuprous sulfide, although there is evidence that a zinc sulfide surface can also be bonded well, provided the growth of the zinc sulfide layer is high enough to provide a sufficient number of points of attachment to the polysulfide crosslinks.

Polarized optical micrographs of two gratings on an AE film with their fringes parallel (left) and perpendicular (right) to the strain direction after relaxation from a stretched state are shown in the Figure.
Parosteal Sarcoma (1968)

<h3>To the Editor:—</h3> The report of a case by McNamara et al (<b>205</b>:535, 1968) of late pulmonary metastasis 17 years and 33 years after amputation for osteogenic sarcoma was interesting but perhaps should have some clarification. There is a special type of osteogenic sarcoma that is slow-growing and of low-grade malignancy, which is more common in females, and the most frequent site is the lower end of the femur, presenting posteriorly as an extraosseous mass. This was described by Geschickter and Copeland (<i>Ann Surg</i><b>133</b>:790-806, 1951) as a new entity which they called parosteal osteoma. It is also known as parosteal sarcoma and juxtacortical osteogenic sarcoma. From the site of the primary tumor and the subsequent course of McNamara's patient, it seems reasonable to assume that what was in 1933 reported as osteogenic sarcoma would now be called parosteal sarcoma. The slow development and late appearance of the metastases
The temporal development of hollow cathode discharges (2003)

Summary Form only given, as follows. A linear discharge system with a plane anode and a hollow cathode was used to study discharges in He at pressures between 100 mtorr and several torr. A 10- mu s voltage pulse of variable amplitude was applied to the electrodes, and the discharge voltage and current were measured. Two distinct discharge modes were observed, a high-current (>100 A) mode and a low current (<500 mA) mode. The two modes represent different stages in the development of the hollow cathode discharge, which is described here. By applying an axial magnetic field it was possible to influence the transition from low-current to high-current mode. In a pressure range of about 200 mtorr the application of a magnetic field of greater than 0.15 T inhibited the occurrence of the high-current discharge. Magnetic fields below this value had no effect on the temporal development of the discharge. A possible explanation is that at lower fields the electrons in the hollow cathode exhibit cycloidal motion as in a magnetron where the hollow cathode discharge places a positive space-charge in the center of the hole. If the magnetic field is increased above a certain critical value the space-charge region can not be sustained.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">></ETX>
Transition to parametric wave patterns in a vertically oscillated granular layer (1994)

Experiments on vertically oscillated granular layers reveal, at a critical acceleration, a well-defined transition from a flat surface to standing wave patterns oscillating at half the excitation frequency. The patterns observed in a cylindrical container are squares or stripes; a continuous transition between these states occurs when the vibration frequency is varied at constant acceleration. The dispersion relation for these parametric granular waves is similar to that for gravity waves in a fluid, but exhibits a well-defined cutoff associated with the particle size.
Longitudinal guided waves confined in radius filler regions of composite joints (2016)

This paper studies the feasibility of using ultrasonic guided waves for fast inspection of conformal deltoid radius filler or "Noodle" regions of joints in stringer composite structures. Semi-analytical finite element simulations, supported by experiments and three-dimensional finite element models, are used to demonstrate the existence of a longitudinal guided ultrasonic mode confined or trapped in the Noodle regions. Studies reveal that this mode has attractive properties for rapid screening of Noodle joints, including strong energy concentration, low dispersion, and attenuation. Discussing the physics of mode confinement in light of material differences and geometry, the phenomenon is shown to be related to feature-guiding effects noted in literature recently.
A Novel Mg2+-dependent O-Methyltransferase in the Phenylpropanoid Metabolism of Mesembryanthemum crystallinum (2003)

Upon irradiation with elevated light intensities, the ice plant (Mesembryanthemum crystallinum) accumulates a complex pattern of methylated and glycosylated flavonol conjugates in the upper epidermal layer. Identification of a flavonol methylating activity, partial purification of the enzyme, and sequencing of the corresponding peptide fragments revealed a novel S-adenosyl-l-methionine-dependent O-methyltransferase that was specific for flavonoids and caffeoyl-CoA. Cloning and functional expression of the corresponding cDNA verified that the new methyltransferase is a multifunctional 26.6-kDa Mg(2+)-dependent enzyme, which shows a significant sequence similarity to the cluster of caffeoyl coenzyme A-methylating enzymes. Functional analysis of highly homologous members from chickweed (Stellaria longipes), Arabidopsis thaliana, and tobacco (Nicotiana tabacum) demonstrated that the enzymes from the ice plant, chickweed, and A. thaliana possess a broader substrate specificity toward o-hydroquinone-like structures than previously anticipated for Mg(2+)-dependent O-methyltransferases, and are distinctly different from the tobacco enzyme. Besides caffeoyl-CoA and flavonols, a high specificity was also observed for caffeoylglucose, a compound never before reported to be methylated by any plant O-methyltransferase. Based on phylogenetic analysis of the amino acid sequence and differences in acceptor specificities among both animal and plant O-methyltransferases, we propose that the enzymes from the Centrospermae, along with the predicted gene product from A. thaliana, form a novel subclass within the caffeoyl coenzyme A-dependent O-methyltransferases, with potential divergent functions not restricted to lignin monomer biosynthesis.

Neighbor-cell assisted error correction for MLC NAND flash memories (2014)

Continued scaling of NAND flash memory to smaller process technology nodes decreases its reliability, necessitating more sophisticated mechanisms to correctly read stored data values. To distinguish between different potential stored values, conventional techniques to read data from flash memory employ a single set of reference voltage values, which are determined based on the overall threshold voltage distribution of flash cells. Unfortunately, the phenomenon of program interference, in which a cell's threshold voltage unintentionally changes when a neighboring cell is programmed, makes this conventional approach increasingly inaccurate in determining the values of cells.

Network assisted small cell discovery in multi-layer and mmWave networks (2015)

With the exponentially increasing capacity demands anticipated in next generation wireless networks, densifying the network using cmW and mmW small cells supporting high bandwidths is seen to be the trend in 5G networks. Such ultra-dense deployment of cells would also lead to a higher amount of power consumption, from the UE and network perspective, due to the increased measurement requirements and higher number of nodes, which consume more power. In this paper, we consider a dense heterogeneous small cell network, where mechanisms are proposed to enable UE power consumption optimizations by conducting inter-frequency measurement when the probability of connecting to a mmW cell is high. Network power consumption is optimized by activating the mmW layer only when there are UEs in the proximity. Based on the performance evaluations done on the proposed mechanism, significant power savings both from UE and network perspective are observed.
Inverse staggered poly-Si and amorphous Si double structure TFT's for LCD panels with peripheral driver circuits integration (1996)

Inverse staggered polycrystalline silicon (poly-Si) and hydrogenated amorphous silicon (a-Si:H) double structure thin-film transistors (TFT's) are fabricated based on the conventional a-Si:H TFT process on a single glass substrate. After depositing a thin (20 nm) a-Si:H using the plasma CVD technique at 300/spl deg/C, Ar/sup +/ and XeCl (300 mJ/cm/sup 2/) lasers are irradiated successively, and then a thick a-Si:H (200 nm) and n/sup +/ Si layers are deposited again. The field effect mobilities of 10 and 0.5 cm /sup 2//V/spl middot/s are obtained for the laser annealed poly-Si and the a-Si:H (without annealing) TFT's, respectively.
Multilayer graphene condenser microphone (2015)

Vibrating membranes are the cornerstone of acoustic technology, forming the backbone of modern loudspeakers and microphones. Acoustic performance of condenser microphone is derived mainly from the membrane's size and achievable static tension. The widely studied and available nickel has been the one of dominant membrane material for several decades. In this paper we introduce multilayer graphene as membrane material for a condenser microphone. The graphene device outperforms a high end commercial nickel-based microphone over a significant part of the acoustic spectrum, with a larger than 10 dB enhancement of sensitivity. Our experimental results are supported with numerical simulations, which show that a 300 layer thick graphene membrane under maximum tension would offer excellent extension of the frequency range, up to 1 MHz, with similar sensitivity as commercial condenser microphones.
Methylphosphonate mapping of phosphate contacts critical for RNA recognition by the human immunodeficiency virus tat and rev proteins (1994)

The HIV-1 regulatory proteins tat and rev are both RNA binding proteins which recognize sequences in duplex RNA which are close to structural distortions. Here we identify phosphate contacts which are critical for each binding reaction by use of a new method. Model RNA binding sites are constructed carrying substitutions of individual phosphodiesters by uncharged methylphosphonate derivatives isolated separately as Rp and Sp diastereoisomers and tested for protein binding by competition assays. In the binding of tat to the trans-activation response region (TAR), three phosphates, P21 and P22 which are adjacent to the U-rich bulge and P40 on the opposite strand, are essential and in each case both isomers inhibit binding. Similarly, in the interaction between the HIV-1 rev protein and the rev-responsive element (RRE) both methylphosphonate isomers at P103, P104, P124 and P125 interfere with rev binding. At P106, only the Rp methylphosphonate isomer is impaired in rev binding ability and it is proposed that the Rp oxygen is hydrogen-bonded to an uncharged amino acid or to a main chain hydrogen atom. Synthetic chemistry techniques also provide evidence for the conformations of non-Watson-Crick G106:G129 and G105:A131 base-pairs in the RRE 'bubble' structure upon rev binding. Almost all functional groups on the 5 bulged residues in the bubble have been ruled out as sites of contact with rev but, by contrast, the N7-positions of each G residue in the flanking base-pairs are identified as sites of likely hydrogen-bonding to rev. The results show that both tat and rev recognize the major groove of distorted RNA helixes and that both proteins make specific contacts with phosphates which are displaced from the sites of base-pair contact.
Green fluorescent protein-cell wall fusion proteins are covalently incorporated into the cell wall of Saccharomyces cerevisiae (1998)

Tagging of two cell wall mannoproteins, Cwp1p and Cwp2p, in Saccharomyces cerevisiae with the green fluorescent protein from Aequorea victoria resulted in incorporation of fluorescent fusion proteins into the cell wall. Both living cells and isolated cell walls became brightly labeled. Intriguingly, the incorporation patterns of both fusion proteins differed. Western analysis of enzymatically released fusion proteins showed that they were covalently linked to the β-1,6-glucan part of the cell wall. Removal of the glycosylphosphatidyl-inositol anchor signal sequence of the green fluorescent protein-cell wall protein fusion proteins resulted in secretion of the proteins into the culture medium. These results indicate that green fluorescent protein-cell wall protein fusion proteins can be used as a convenient fluorescent marker to study the incorporation of specific cell wall proteins and the control mechanisms involved.

Enzymatic reaction with unnatural substrates: DNA photolyase ( <i>Escherichia coli</i> ) recognizes and reverses thymine [2+2] dimers in the DNA strand of a DNA/PNA hybrid duplex (1998)

Peptide nucleic acids (PNA) are mimics with normal bases connected to a pseudopeptide chain that obey Watson-Crick rules to form stable duplexes with itself and natural nucleic acids. This has focused attention on PNA as therapeutic or diagnostic reagents. Duplexes formed with PNA mirror some but not all properties of DNA. One fascinating aspect of PNA biochemistry is their reaction with enzymes. Here we show an enzyme reaction that operates effectively on a PNA/DNA hybrid duplex. A DNA oligonucleotide containing a cis, syn-thymine [2+2] dimer forms a stable duplex with PNA. The hybrid duplex is recognized by photolyase, and irradiation of the complex leads to the repair of the thymine dimer. This finding provides insight into the enzyme mechanism and provides a means for the selective repair of thymine photodimers.
User Clustering in Online Advertising via Topic Models (2015)

In the domain of online advertising, our aim is to serve the best ad to a user who visits a certain webpage, to maximize the chance of a desired action to be performed by this user after seeing the ad. While it is possible to generate a different prediction model for each user to tell if he/she will act on a given ad, the prediction result typically will be quite unreliable with huge variance, since the desired actions are extremely sparse, and the set of users is huge (hundreds of millions) and extremely volatile, i.e., a lot of new users are introduced everyday, or are no longer valid. In this paper we aim to improve the accuracy in finding users who will perform the desired action, by assigning each user to a cluster, where the number of clusters is much smaller than the number of users (in the order of hundreds). Each user will fall into the same cluster with another user if their event history are similar. For this purpose, we modify the probabilistic latent semantic analysis (pLSA) model by assuming the independence of the user and the cluster id, given the history of events. This assumption helps us to identify a cluster of a new user without re-clustering all the users. We present the details of the algorithm we employed as well as the distributed implementation on Hadoop, and some initial results on the clusters that were generated by the algorithm.
