Maximum Ratio Transmission for Space-Polarization Division Multiple Access in Dual-Polarized MIMO System (2015)

The phenomena of higher channel cross polarization discrimination (XPD) is mainly observed for future wireless technologies such as small cell network and massive multiple-input multiple-output (MIMO) system. Therefore, utilization of high XPD is very important and space-polarization division multiple access (SPDMA) with dual-polarized MIMO system could be a suitable solution to high-speed transmission in high XPD environment as well as reduction of array size at base station (BS). By SPDMA with dual-polarized MIMO system, two parallel data signals can be transmitted by both vertically and horizontally polarized antennas to serve different mobile stations (MSs) simultaneously compare to conventional space division multiple access (SDMA) with single-polarized MIMO system. This paper analyzes the performance of SPDMA for maximum ratio transmission (MRT) in time division duplexing (TDD) system by proposed dual-polarized MIMO spatial channel model (SCM) compare to conventional SDMA. Simulation results indicate that how SPDMA utilizes the high XPD as the number of MS increases and SPDMA performs very close to conventional SDMA for same number of antenna elements but half size of the array at BS.
Information optimal compressive x-ray threat detection (2016)

We present an information-theoretic approach to X-ray measurement design for threat detection in passenger bags. Unlike existing X-ray systems that rely of a large number of sequential tomographic projections for threat detection based on 3D reconstruction, our approach exploits the statistical priors on shape/material of items comprising the bag to optimize multiplexed measurements that can be used directly for threat detection without an intermediate 3D reconstruction. Simulation results show that the optimal multiplexed design achieves higher probability of detection for a given false alarm rate and lower probability of error for a range of exposure (photon) budgets, relative to the non-multiplexed measurements. For example, a 99% detection probability is achieved by optimal multiplexed design requiring 4x fewer measurements than non-multiplexed design.

Loss of N-Linked Glycosylation from the Hemagglutinin- Neuraminidase Protein Alters Virulence of Newcastle Disease Virus (2004)

The hemagglutinin-neuraminidase (HN) protein of Newcastle disease virus (NDV) is an important determinant of its virulence. We investigated the role of each of the four functional N-linked glycosylation sites (G1 to G4) of the HN glycoprotein of NDV on its pathogenicity. The N-linked glycosylation sites G1 to G4 at residues 119, 341, 433, and 481, respectively, of a moderately pathogenic NDV strain Beaudette C (BC) were eliminated individually by site-directed mutagenesis on a full-length cDNA clone of BC. A double mutant (G12) was also created by eliminating the first and second glycosylation sites at residues 119 and 341, respectively. Infectious virus was recovered from each of the cDNA clones of the HN glycoprotein mutants, employing a reverse genetics technique. There was a greater delay in the replication of G4 and G12 mutant viruses than in the parental virus. Loss of glycosylation does not affect the receptor recognition by HN glycoprotein of NDV. The neuraminidase activity of G4 and G12 mutant viruses and the fusogenicity of the G4 mutant virus were significantly lower than those of the parental virus. The fusogenicity of the double mutant virus (G12) was significantly higher than that of the parental virus. Cell surface expression of the G4 virus HN was significantly lower than that of the parental virus. The antigenic reactivities of the mutants to a panel of monoclonal antibodies against the HN protein indicated that removal of glycosylation from the HN protein increased (G1, G3, and G12) or decreased (G2 and G4) the formation of antigenic sites, depending on their location. In standard tests to assess virulence in chickens, all of the glycosylation mutants were less virulent than the parental BC virus, but the G4 and G12 mutants were the least virulent.
X-MANO: An open-source platform for cross–domain management and orchestration (2017)

In the recent years several proprietary as well as open-source frameworks for network service orchestration have emerged. Similarly a significant body of literature has been produced investigating both the theoretical and practical aspects of network service orchestration. Nevertheless, currently available frameworks for network service orchestration are designed under the assumption that they can have full control over the resources being orchestrated. Such assumption does not hold any more when there is the need to pool both physical and virtual resources across different technological and administrative domains in order to deploy a service. In such a scenario, the different infrastructure providers may be reluctant to provide full access to their resources to a third party. In this paper we present X-MANO, a cross-domain network service orchestration framework. X-MANO is effectively deployment-agnostic and can be used in hierarchical, peer-to-peer and cascading (or recursive) configuration. We validate X-MANO through a proof-of-concept implementation over a multi-domain testbed. Finally, we release all the code under a permissive APACHE 2.0 license making it available to researchers and practitioners.

Generating and drawing area-proportional euler and venn diagrams (2007)

An Euler diagram C = {c 1, c2, . . . , cn} is a collection of n simple closed curves (i.e., Jordan curves) that partition the plane into connected subsets, called regions, each of which is enclosed by a unique combination of curves. Typically, Euler diagrams are used to visualize the distribution of discrete characteristics across a sample population; in this case, each curve represents a characteristic and each region represents the sub-population possessing exactly the combination of containing curves' properties. Venn diagrams are a subclass of Euler diagrams in which there are 2n regions representing all possible combinations of curves (e.g., two partially overlapping circles). In this dissertation, we study the Euler Diagram Generation Problem (EDGP), which involves constructing an Euler diagram with a prescribed set of regions. We describe a graph-theoretic model of an Euler diagram's structure and use this model to develop necessary-and-sufficient existence conditions. We also use the graph-theoretic model to prove that the EDGP is NP-complete. In addition, we study the related Area-Proportional Euler Diagram Generation Problem (ω-EDGP), which involves constructing an Euler diagram with a prescribed set of regions, each of which has a prescribed area. We develop algorithms for constructing area-proportional Euler diagrams composed of up to three circles and rectangles, as well as diagrams with an unbounded number of curves and a region of common intersection. Finally, we present implementations of our algorithms that allow the dynamic manipulation and real-time construction of area-proportional Euler diagrams.
Abstract LB-35: Site specific activation of AKT protects cells from death induced by glucose deprivation . (2013)

Abstract The serine/threonine kinase AKT is a key mediator of cancer cell survival. We demonstrate that transient glucose deprivation modestly induces AKT phosphorylation at both Thr308 and Ser473. In contrast, prolonged glucose deprivation induces selective AKT phosphorylation at Thr308 and phosphorylation of a distinct subset of AKT downstream targets leading to cell survival under metabolic stress. Glucose deprivation-induced AKT Thr308 phosphorylation is dependent on PDK1 and PI3K but not EGFR or IGF1R. Prolonged glucose-deprivation induces the formation of a complex of AKT, PDK1, and the GRP78 chaperone protein, directing phosphorylation of AKT at Thr308 but not Ser473. Our results reveal a novel mechanism of AKT activation under prolonged metabolic stress that protects cells from metabolic stress. The selective activation of AKT phosphorylation at Thr308 that occurs during prolonged nutrient deprivation may provide an unexpected opportunity for the development and implementation of drugs targeting cell metabolism and aberrant AKT signaling.

Design of a line-VISAR interferometer system for the Sandia Z Machine (2017)

A joint team comprised of Lawrence Livermore National Laboratory (LLNL) and Sandia National Laboratory (SNL) personnel is designing a line-VISAR (Velocity Interferometer System for Any Reflector) for the Sandia Z Machine, Z Line-VISAR. The diagnostic utilizes interferometry to assess current delivery as a function of radius during a magnetically-driven implosion. The Z Line-VISAR system is comprised of the following: a two-leg line-VISAR interferometer, an eight-channel Gated Optical Imager (GOI), and a fifty-meter transport beampath to/from the target of interest. The Z Machine presents unique optomechanical design challenges. The machine utilizes magnetically driven pulsed power to drive a target to elevated temperatures and pressures useful for high energy density science. Shock accelerations exceeding 30g and a strong electromagnetic pulse (EMP) are generated during the shot event as the machine discharges currents of over 25 million amps. Sensitive optical components must be protected from shock loading, and electrical equipment must be adequately shielded from the EMP. The optical design must accommodate temperature and humidity fluctuations in the facility as well as airborne hydrocarbons from the pulsed power components. We will describe the engineering design and concept of operations of the Z Line-VISAR system. Focus will be on optomechanical design.
BMP‐2 Signaling and Mechanotransduction Synergize to Drive Osteogenic Differentiation via YAP/TAZ (2020)

Growth factors and mechanical cues synergistically affect cellular functions, triggering a variety of signaling pathways. The molecular levels of such cooperative interactions are not fully understood. Due to its role in osteogenesis, the growth factor bone morphogenetic protein 2 (BMP-2) is of tremendous interest for bone regenerative medicine, osteoporosis therapeutics, and beyond. Here, contribution of BMP-2 signaling and extracellular mechanical cues to the osteogenic commitment of C2C12 cells is investigated. It is revealed that these two distinct pathways are integrated at the transcriptional level to provide multifactorial control of cell differentiation. The activation of osteogenic genes requires the cooperation of BMP-2 pathway-associated Smad1/5/8 heteromeric complexes and mechanosensitive YAP/TAZ translocation. It is further demonstrated that the Smad complexes remain bound onto and active on target genes, even after BMP-2 removal, suggesting that they act as a "molecular memory unit." Thus, synergistic stimulation with BMP-2 and mechanical cues drives osteogenic differentiation in a programmable fashion.

Dual XOR in the Air: A Network Coding Based Retransmission Scheme for Wireless Broadcasting (2011)

In this paper, a novel dual XOR hybrid automatic retransmission request scheme XOR <sup xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">2</sup> -HARQ is proposed for wireless broadcasting. Distinct from the traditional network coding (NC) based HARQ (NC-HARQ), an additional XOR operation is introduced to dynamically combine lost packets from the individual receiver instead of conducting XOR operation only across lost packets from different receivers. Furthermore, based on the linear block code's perspective, we optimize the retransmission strategy to yield optimal diversity gain. Analytical results show that conditioned on the same packet error ratio (PER), the retransmission rounds needed for XOR <sup xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">2</sup> -HARQ is strictly less than that of NC-HARQ, and the simulation results consolidate our analysis to show a significant reduction of required retransmissions.
Engineering Selectivity in Heterogeneous Catalysis: Ag Nanowires as Selective Ethylene Epoxidation Catalysts (2008)

Controlling selectivity in heterogeneous catalysis is critical for the design of environmentally friendly catalytic processes that minimize the production of undesired byproducts and operate with high energy efficiency. We show that the Ag nanowire catalysts exhibit higher selectivity in the ethylene epoxidation reaction than conventional spherical particle catalysts. The higher selectivity of the nanowire catalysts was attributed to a higher concentration of the Ag(100) surface facets in the nanowire catalysts compared to the particle catalysts. Density functional theory calculations show that the transformation of the surface oxametallacycle intermediate to form the selective product, EO, is more favorable on the Ag(100) than on Ag(111). The studies show that recent advances in the controlled synthesis of uniform nanostructures with well-defined surface facets might provide an important platform for the design of highly selective heterogeneous catalysts.
Additive manufacturing methods and modelling approaches: a critical review (2015)

Additive manufacturing is a technology rapidly expanding on a number of industrial sectors. It provides design freedom and environmental/ecological advantages. It transforms essentially design files to fully functional products. However, it is still hampered by low productivity, poor quality and uncertainty of final part mechanical properties. The root cause of undesired effects lies in the control aspects of the process. Optimization is difficult due to limited modelling approaches. Physical phenomena associated with additive manufacturing processes are complex, including melting/solidification and vaporization, heat and mass transfer etc. The goal of the current study is to map available additive manufacturing methods based on their process mechanisms, review modelling approaches based on modelling methods and identify research gaps. Later sections of the study review implications for closed-loop control of the process.
Specificity of Human Antibodies Reactive with Pneumococcal C Polysaccharide (2000)

Antibodies reactive with C polysaccharide (PS) were found in healthy adults, pneumococcal patients, and vaccinees. These antibodies were not directed to the phosphocholine determinant of the C PS, as they appear to be in mice, since the human antibodies were inhibitable only with C PS. We found another population of phosphocholine-specific antibodies inhibitable only by phosphocholine and related compounds.
Deep Crustal Geothermal Measurements, Hole 504B, Deep Sea Drilling Project Legs 69, 70, 83, and 92 (1985)

We report an extensive suite of geothermal measurements in the deepest borehole yet drilled into the oceanic crust, Hole 5O4B of the Deep Sea Drilling Project. Located in 5.9 m.y.-old crust of the Costa Rica Rift, Hole 504B was cored during Legs 69 and 70 in late 1979 and Leg 83 in late 1981, to a total depth of 1350 m beneath the seafloor, through 274.5 m of sediment and 1075.5 m of basalt. During the three drilling legs, downhole temperatures were logged 11 times, and the thermal conductivities of 239 sediment and basalt samples were measured. Temperatures were logged a twelfth time during Leg 92 in 1983. The results indicate a dominantly conductive mode of heat transfer through the complete section, at 190 10 mW/m 2 . This is consistent with the predicted plate heat transfer and the hypothesis that the thick sediment cover acts as a seal against hydrothermal circulation of seawater to basement.
Evidence that Lactobacillus bulgaricus in yogurt is stimulated by carbon dioxide produced by Streptococcus thermophilus (1982)

Until now it has been assumed that the protocooperation of yogurt bacteria, Streptococcus thermophilus and Lactobacillus bulgaricus, consisted of the production of amino acids and small peptides by the lactobacilli and the production of formic acid by the streptococci. These compounds were the known limiting substrates in milk. From studies with continuous cultures and de-aerated milk it appeared that the protocooperation of yogurt bacteria could not be explained completely by the production of these above-mentioned compounds. A continuous pure culture of L. bulgaricus Ib in milk to which sodium formate was added, was diluted out under the conditions of growth of the continuous mixed yogurt culture. Evidence is given that L. bulgaricus Ib needs more than or equal to 31 mg carbon dioxide per kg milk for optimal growth. L. bulgaricus, as a pure culture, can grow in milk as fast as when it forms part of a mixed culture, provided that to the milk 40 mg sodium formate and more than or equal to 31 mg carbon dioxide per kg are added. It was found that S. thermophilus Sts in milk produced carbon dioxide in excess for the optimal growth of L. bulgaricus Ib. The initial amount of carbon dioxide present in yogurt milk was determined. It was established to what extent carbon dioxide is an essential element of the protocooperation under practical conditions. Removal of carbon dioxide during heat treatment (or evacuation) of yogurt milk does not appreciably retard the acid production of the mixed culture, due to the rapid formation of carbon dioxide by S. thermophilus.
Repression of Quiescence-Specific Polypeptides in Chicken Heart Mesenchymal Cells Transformed by Rous Sarcoma Virus (1987)

Chicken heart mesenchymal cells do not proliferate in medium of physiological composition containing plasma (S. Balk, Proc. Natl. Acad. Sci. USA 77:6606-6610, 1980). To understand the molecular events involved in cell quiescence and in the initiation of cell division under physiological conditions, we examined the differences in the patterns of protein synthesis of quiescent, hormone-stimulated, and Rous sarcoma virus-transformed chicken heart mesenchymal cells. We describe the expression of a 20,000-kilodalton (kDa) polypeptide actively synthesized by quiescent cells but not by their transformed counterparts. Normal chicken heart mesenchymal cells stimulated with epidermal growth factor and insulin also repressed the synthesis of the 20,000-kDa polypeptide while actively growing but synthesized increasing amounts of the protein at high cell density (confluence). The synthesis of the 20,000-kDa protein is not restricted to chicken heart mesenchymal cells, since confluent, density-arrested chicken embryo fibroblasts also expressed high levels of the protein. Transformed chicken heart mesenchymal cells and embryo fibroblasts did not synthesize the protein even at high cell density. The 20,000-kDa polypeptide accumulated in the culture medium.
Etude de l'effet de masse chez Trichogramma maidis (Hym., Trichogrammatidae) dans le cas d'un superparasitisme réduit (1984)

L'tude de l'effet de masse dans des groupes de taille croissante et de taux sexuel diffrent, lorsque le superparasitisme est rduit, permet de mettre en vidence les interactions comportementales entre individus mles et femelles. La descendance et la longvit, aprs une diminution plus ou moins importante et rapide en fonction de l'importance du groupe et de la proportion des mles, montrent une relative stabilisation. Simultanment, la baisse du taux sexuel de la progniture serait essentiellement due la rponse de la femelle des stimuli provenant du groupe d'individus (fcondation moins frquente des oeufs).
Tangier Disease (1978)

Normal high-density lipoproteins are absent from plasma in Tangier disease, and the disorder is characterized by accumulation of cholesteryl esters in several tissues, particularly those of the reticuloendothelial system. Electron microscopy of the abnormal high-density lipoproteins in the plasma of three patients with Tangier diseases revealed large (68-nm), flattened, translucent particles in all cases. These particles were most abundant in the plasma of the splenectomized patient. Restriction of dietary fat eliminated or drastically reduced the numbers of these particles among the Tangier high-density lipoproteins. Thus abnormal products of chylomicron metabolism that appear to occur in plasma in this disorder may be targets for phagocytosis and may be at least one source of the cholesteryl esters that accumulate in reticuloendothelial tissues in Tangier disease.
