Deepwater OBN and Source Designature - Using the Information in the Data and Improving the Processing (2015)

Summary For deepwater ocean bottom node (OBN) data, the bubble tail of the source signature appears stronger than in comparable surface seismic surveys; it masks shallow events and limits the upgoing-data-only window in the shallow part of the section. As source signatures are not commonly recorded during OBN surveys, source signatures have to be modeled or extracted from the data in order to be used for debubble/designature. A global signature is extracted from the data and used to suppress the bubbles in the signature. This reveals that there are shot to shot variations in the signature. Signatures are estimated for all shots with nodes in the near offsets, and these source signatures are used to perform designature on a shot-by-shot basis. The designature process improves the shallow data and yields a much better dataset for calibration of the vertical particle motion measurement, Z to the hydrophone measurement, P, which is based on a shallow window with only upgoing data.
Transgenic Plants and Biosafety: Science, Misconceptions and Public Perceptions (2000)

One usually thinks of plant biology as a non-controversial topic, but the concerns raised over the biosafety of genetically modified (GM) plants have reached disproportionate levels relative to the actual risks. While the technology of changing the genome of plants has been gradually refined and increasingly implemented, the commercialization of GM crops has exploded. Today's commercialized transgenic plants have been produced using Agrobacterium tumefaciens-mediated transformation or gene gun-mediated transformation. Recently, incremental improvements of biotechnologies, such as the use of green fluorescent protein (GFP) as a selectable marker, have been developed. Non-transformation genetic modification technologies such as chimeraplasty will be increasingly used to more precisely modify germplasm. In spite of the increasing knowledge about genetic modification of plants, concerns over ecological and food biosafety have escalated beyond scientific rationality. While several risks associated with GM crops and foods have been identified, the popular press, spurred by colorful protest groups, has left the general public with a sense of imminent danger. Reviewed here are the risks that are currently under research. Ecological biosafety research has identified potential risks associated with certain crop/transgene combinations, such as intra- and interspecific transgene flow, persistence and the consequences of transgenes in unintended hosts. Resistance management strategies for insect resistance transgenes and non-target effects of these genes have also been studied. Food biosafety research has focused on transgenic product toxicity and allergenicity. However, an estimated 3.5 x 10(12) transgenic plants have been grown in the U.S. in the past 12 years, with over two trillion being grown in 1999 and 2000 alone. These large numbers and the absence of any negative reports of compromised biosafety indicate that genetic modification by biotechnology poses no immediate or significant risks and that resulting food products from GM crops are as safe as foods from conventional varieties. We are increasingly convinced that scientists have a duty to conduct objective research and to effectively communicate the results--especially those pertaining to the relative risks and potential benefits--to scientists first and then to the public. All stakeholders in the technology need more effective dialogues to better understand risks and benefits of adopting or not adopting agricultural biotechnologies.
Abductor hallucis false motor points: Electrophysiologic mapping and cadaveric dissection (1996)

False motor points (FMPs) can occur in intrinsic foot or hand muscles, causing spuriously prolonged distal motor latencies by misrepresenting the compound muscle action potential (CMAP) onset. We investigated the motor point (MP) and possible FMPs in abductor hallucis (AH) by three methods: (1) electrophysiologic mapping of the CMAP with a grid of approximately 29 G1 sites over AH (n = 20), including commonly used MPs just anterior to (Ant-MP) and posterior to (Post-MP) the navicular tuberosity; (2) electrophysiologic mapping with direct percutaneous threshold stimulation of AH (same grid as above); and (3) cadaveric dissection (n = 4). We found AH FMPs in 19 of 20 feet (2.7 FMPs/foot) which resulted in prolongation of the CMAP onset latency by 0.5-2.3 ms. Post-MP had a significantly lower mean threshold stimulus intensity than all other grid sites, including the FMPs. The anatomic MP of AH was consistently found just inferior and posterior to the navicular tuberosity. This study demonstrates that AH FMPs: (1) can be identified in virtually all feet; (2) do not correspond to the true MP (i.e., Post-MP); and (3) are likely due to superimposed compound action potentials from nearby muscles or nerves.
Three Dimensional Design of Large-Scale TiO<sub>2</sub> Nanorods Scaffold Decorated by Silver Nanoparticles as SERS Sensor for Ultrasensitive Malachite Green Detection (2012)

We have designed a large-scale three-dimensional (3D) hybrid nanostructure as surface-enhanced Raman scattering (SERS) sensor by decorating silver nanoparticles on TiO2 nanorods scaffold (Ag/TiO2). Taking p-mercaptobenzoic acid (PMBA) as the probe molecule, the SERS signals collected by point-to-point and time mapping modes show that the relative standard deviation (RSD) in the intensity of the main Raman vibration modes (1079, 1586 cm(-1)) is less than 10%, demonstrating good spatial uniformity and time stability. This hybrid substrate also exhibits excellent SERS enhancement effect due to the formation of high-density hot spots among the AgNPs, which was proved by finite-difference time-domain (FDTD) simulations. The application of the new nanostructures as SERS sensors was demonstrated with the detection of malachite green (MG). The quantification of MG can be accomplished with the detection limit of 1 × 10(-12) M based on the Raman intensity. The results show that the Ag/TiO2 nanostructure can be a promising candidate for SERS sensor.
A facile route of polythiophene nanoparticles via Fe<sup>3+</sup>‐catalyzed oxidative polymerization in aqueous medium (2008)

Abstract We have demonstrated that unsubstituted thiophene can be polymerized by Fe 3+ ‐catalyzed oxidative polymerization inside nanosized thiophene monomer droplets, that is, nanoreactors, dispersed in aqueous medium, which can be performed under acidic solution conditions with anionic surfactant. Besides, we proposed a synthetic mechanism for the formation of the unsubstituted polythiophene nanoparticles in aqueous medium. This facile method includes a FeCl 3 /H 2 O 2 (catalyst/oxidant) combination system, which guarantees a high conversion (ca. 99%) of thiophene monomers with only a trace of FeCl 3 . The average particle size was about 30 nm, within a narrow particle‐size distribution (PDI = 1.15), which resulted in a good dispersion state of the unsubstituted polythiophene nanoparticles. Hansen solubility parameters were introduced to interpret the dispersion state of the polythiophene nanoparticles with various organic solvents. The UV–Visible absorption and photoluminescence (PL) spectrum were measured to investigate the light emitting properties of the prepared unsubstituted polythiophene nanoparticle emulsions. According to non‐normalized PL analysis, the reduced total PL intensity of the polythiophene nanoparticle emulsions can be rationalized by self‐absorption in a wavelength range less than 500 nm. © 2008 Wiley Periodicals, Inc.

Newcastle disease virus-based MERS-CoV candidate vaccine elicits high-level and lasting neutralizing antibodies in Bactrian camels (2017)

Middle East respiratory syndrome coronavirus (MERS-CoV), a member of the <i>Coronaviridae</i> family, is the causative pathogen for MERS that is characterized by high fever, pneumonia, acute respiratory distress syndrome (ARDS), as well as extrapulmonary manifestations. Currently, there are no approved treatment regimens or vaccines for MERS. Here, we generated recombinant nonvirulent Newcastle disease virus (NDV) LaSota strain expressing MERS-CoV S protein (designated as rLa-MERS-S), and evaluated its immunogenicity in mice and Bactrian camels. The results revealed that rLa-MERS-S showed similar growth properties to those of LaSota in embryonated chicken eggs, while animal immunization studies showed that rLa-MERS-S induced MERS-CoV neutralizing antibodies in mice and camels. Our findings suggest that recombinant rLa-MERS-S may be a potential MERS-CoV veterinary vaccine candidate for camels and other animals affected by MERS.
Efficient Mapping Scheme for Parallel Processing (1996)

This paper presents a mapping scheme for parallel processing using an accurate characterization of the communication overhead. A set of objective functions is formulated to evaluate the optimality of mapping a problem graph into a system graph. One of them is especially suitable for real-time applications of parallel processing. These objective functions are different from the conventional objective functions in that the edges in the problem graph are weighted and the actual distance rather than the nominal distance for the edges in the system graph is employed. This facilitates a more accurate qualification of the communication overhead. An efficient mapping scheme has been developed for the objective functions, where two levels of assignment optimization procedures are employed: initial assignment and pairwise exchange. The mapping scheme has been tested using the hypercube as a system graph.
A Fair Payment Protocol for Cascading P2P Transaction (2011)

As an emerging decentralized technology, peer- to-peer architecture arises as a new model for distributed computing and transaction, consequently there is a need for a scheme to incorporate payment services in this environment to enable electronic payment via peer-to-peer systems. In this paper, a transferable token is proposed for peer-to-peer payment system, which can float from a peer to another peer. When this kind of token is used, the fraud such as double spending can be found out but the broker need not be involved online in the payment. The optimistic payment protocol for both the basic payment and the cascading payment are presented. The disputes which might occur are analyzed and handling solution is proposed. The arbitrator need not be involved unless disputes have occurs. The optimistic payment scheme is efficient, practical and suitable for peer-to-peer transaction.
The origins, uses, and fate of the EDVAC (1993)

It is well known that the EDVAC was the first general-purpose electronic digital stored-program computer to be designed. What is not so well known is that the EDVAC was nowhere near the first computer to be operational, was not actually constructed according to the initial design, was not reliable when constructed, and was eventually so heavily modified that it would have been almost unrecognizable to the original design team. The origins, designs, and construction of EDVAC are discussed. EDVAC's software and later modifications are reviewed.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">></ETX>

Extended path prediction using camera and map data for lane keeping support (2005)

Lane departure or lane keeping systems should detect in advance not only if a road/lane departure would occur, but also when it would happen. The goal of the paper is twofold; on one hand achieves accurate detection of such incidents decreasing system misses; on the other hand it extends the electronic horizon of the supervised area to 500 m minimizing false alarms caused by intentional lane changes. To achieve the goals, the paper proposes an extended lane tracking scheme based on an information fusion system, map and camera data, and a path prediction algorithm that incorporates curvilinear vehicle models for the short term prediction and on-line learning for a wider time perspective. The presented algorithm is tested using simulated and real map, camera and vehicle data.
Sixteenth Century Essays and Studies (Volume II) (1969)

One way out of this impasse may be to search for the external conditions that produced and shaped German Anabaptism.There is, first of all, the question of popular religious movements before Anabaptism.Zeman gives the customary, cavalier dismissal to the hypo- theses of Ludwig Keller and Albrecht Ritschl, vi^ho tried to connect Anabaptism with pre- vious sectarian movements, but he cites approvingly the theories of Amadeo Molnar, which point in the same direction.Molnar links the reform movements of the Middle Ages ("the First Reformation") with those of the Reformation era ("the Second Reformation").The Anabaptists fall into the former category, a classification which Zeman disputes, though he is sympathetic with Molnar's schema as a whole.No one would not study English Metho- dism, French Jansenism, the Spanish allumbrados, or the medieval poverty movement as though such movements had no historical antecedents.Why Anabaptism should continue to be an historical orphan, without parents and without causes, is difficult to say.
Employee Rights and Their Impact On Personnel Decisions By Managers in the Hospitality Industry (1989)

Hybrid additive manufacturing of the modified electrolyte‐electrode surface of planar solid oxide fuel cells (2020)

Abstract Digital Control of the surface patterning of functional layers of solid oxide fuel cells (SOFCs), via the inkjet printing technique, offers better efficiency in performance. A combination of inkjet printing and tape casting in a single machine system defines as hybrid additive manufacturing, facilitates printing complex structures. Also, implementing this idea removes the blocking of the print head nozzle orifice issue. In this paper, a highly dispersed and long‐term stable colloidal zirconia‐based suspension, with optimal printability characteristics, is designed to be prepared in approximately three hours to fabricate the macro patterned structure of the SOFC electrolyte. Hybrid Additive Manufacturing is successfully employed to make a symmetric cathode side cell with a modified electrolyte‐electrode surface to reduce the electron resistivity.
Induced Resistance to Meloidogyne hapla by other Meloidogyne species on Tomato and Pyrethrum Plants. (1995)

Advance inoculation of the tomato cv. Celebrity or the pyrethrum clone 223 with host-incompatible Meloidogyne incognita or M. javanica elicited induced resistance to host-compatible M. hapla in pot and field experiments. Induced resistance increased with the length of the time between inoculations and with the population density of the induction inoculum. Optimum interval before challenge inoculation, or population density of inoculum for inducing resistance, was 10 days, or 5,000 infective nematodes per 500-cm(3) pot. The induced resistance suppressed population increase of M. hapla by 84% on potted tomato, 72% on potted pyrethrum, and 55% on field-grown pyrethrum seedlings, relative to unprotected treatments. Pyrethrum seedlings inoculated with M. javanica 10 days before infection with M. hapla were not stunted, whereas those that did not receive the advance inoculum were stunted 33% in pots and 36% in field plots. The results indicated that advance infection of plants with incompatible or mildly virulent nematode species induced resistance to normally compatible nematodes and that the induced resistance response may have potential as a biological control method for plant nematodes.

En este trabajo se discute la situacion que enfrentan las universidades y se plantean alternativas de colaboracion con los solicitantes de servicios ambientales, con objeto de poder satisfacer esta importante demanda social.
Physicochemical properties of lipids: new strategies to manage fatty acid bioavailability. (2004)

Fatty acid bioavailability can be managed through the physicochemical properties of lipid such as lipid-droplet size, lipid-droplet ultrastructure (lipids organization between core and surface), structure of triglycerides and of phospholipids. The lipid-droplet size exhibits a major effect on lipase activity during lipid digestion. The lipid-droplet ultrastructure is a dynamic factor controling lipase interaction at the lipid interface via the surface phospholipid layer, and also lipase activity via the proportion of triglyceride molecules able to locate at the surface. Triglyceride structure affects in a strong manner digestion, absorption and fatty acid metabolism. Finally, optimal fatty acid transport to specific tissues is dependent on the vehicle molecule (triglyceride or ethyl ester or phospholipid). All these aspects provide convincing support for the possibility of using biotechnologically remodeled lipids with specific physicochemical properties for health benefits.
Graph-Based Parallel Large Scale Structure from Motion (2019)

While Structure from Motion (SfM) achieves great success in 3D reconstruction, it still meets challenges on large scale scenes. In this work, large scale SfM is deemed as a graph problem, and we tackle it in a divide-and-conquer manner. Firstly, the images clustering algorithm divides images into clusters with strong connectivity, leading to robust local reconstructions. Then followed with an image expansion step, the connection and completeness of scenes are enhanced by expanding along with a maximum spanning tree. After local reconstructions, we construct a minimum spanning tree (MinST) to find accurate similarity transformations. Then the MinST is transformed into a Minimum Height Tree (MHT) to find a proper anchor node and is further utilized to prevent error accumulation. When evaluated on different kinds of datasets, our approach shows superiority over the state-of-the-art in accuracy and efficiency. Our algorithm is open-sourced at https://github.com/AIBluefisher/GraphSfM.
