Disconnectable Mooring Systems for Arctic Conditions (2015)

Abstract This paper reviews the issues associated with mooring a ship shaped Floating Production Unit (FPU) in arctic conditions, and presents the development of a novel disconnection and reconnection system for such conditions. The mooring systems of FPUs operating in arctic conditions must be disconnectable to allow the FPU to leave the station to avoid collision with icebergs, or to avoid overloading the mooring legs due to sea ice acting on the FPU hull. In the case of sea ice, the FPU may be required to disconnect under much higher loads than the non-arctic disconnectable systems in operation today. A recent study for the design of an arctic mooring system identified a number of key developments that are required before such systems could be deployed. The disconnection system is a safety critical element, and requires high reliability and redundancy to ensure the FPU can always rapidly disconnect from its mooring when required. In addition, the large number of risers that may be installed for these large field developments, combined with the significant suspended weight resulting from the high capacity mooring system, leads to large buoyancy requirement for the buoy which must support the risers and mooring system when disconnected from the vessel. As a consequence the analysis of the reconnection process must account for the coupled behaviour of the large buoy body, the mooring system, and the risers and umbilicals. Such analysis has shown that using conventional disconnectable turret technology, the large buoy size coupled with the requirement to reconnect in heavy sea states, can readily generate snatch loads that would break the pull-in winch wire. In response to the above, this paper presents two significant advances in disconnectable mooring technology. The first is the development of a new locking system to connect the buoy to the turret, which has been qualified at full scale. The second concerns the design of a new pull-in arrangement that eliminates the risk of snatch loads even in sea states in excess of 3m Hs. The system robustness has been demonstrated through model testing.
An efficient finite-difference scheme for electromagnetic logging in 3D anisotropic inhomogeneous media (2003)

Abstract We consider a problem of computing the electromagnetic field in 3D anisotropic media for electromagnetic logging. The proposed finite-difference scheme for Maxwell equations has the following new features based on some recent and not so recent developments in numerical analysis: coercivity (i.e., the complete discrete analogy of all continuous equations in every grid cell, even for nondiagonal conductivity tensors), a special conductivity averaging that does not require the grid to be small compared to layering or fractures, and a spectrally optimal grid refinement minimizing the error at the receiver locations and optimizing the approximation of the boundary conditions at infinity. All of these features significantly reduce the grid size and accelerate the computation of electromagnetic logs in 3D geometries without sacrificing accuracy.

Parenterial iron sucrose-induced renal preconditioning: differential ferritin heavy and light chain expression in plasma, urine, and internal organs (2019)

Experimental data suggest that iron sucrose (FeS) injection, used either alone or in combination with other prooxidants, can induce “renal preconditioning,” in part by upregulating cytoprotective ferritin levels. However, the rapidity, degree, composition (heavy vs. light chain), and renal ferritin changes after FeS administration in humans remain to be defined. To address these issues, healthy human volunteers ( n = 9) and patients with stage 3–4 chronic kidney disease( n = 9) were injected once with FeS (120, 240, or 360 mg). Plasma ferritin was measured from 0 to 8 days postinjection as an overall index of ferritin generation. Urinary ferritin served as a “biomarker” of renal ferritin production. FeS induced rapid (≤2 h), dose-dependent, plasma ferritin increases in all study participants, peaking at approximately three to five times baseline within 24–48 h. Significant urinary ferritin increases (~3 times), without dose-dependent increases in albuminuria, neutrophil gelatinase-associated lipocalin, or N-acetyl-β-d-glucosaminidase excretion, were observed. Western blot analysis with ferritin heavy chain (Fhc)- and light chain (Flc)-specific antibodies demonstrated that FeS raised plasma Flc but not Fhc levels. Conversely, FeS increased both Fhc and Flc in urine. To assess sites of FeS-induced ferritin generation, organs from FeS-treated mice were probed for Fhc, Flc, and their mRNAs. FeS predominantly raised hepatic Flc. Conversely, marked Fhc and Flc elevations developed in the kidney and spleen. No cardiopulmonary ferritin increases occurred. Ferritin mRNAs remained unchanged throughout, implying posttranscriptional ferritin production. We conclude that FeS induces rapid, dramatic, and differential Fhc and Flc upregulation in organs. Renal Fhc and Flc increases, in the absence of nephrotoxicity, suggest potential FeS utility as a clinical renal “preconditioning” agent.
Chikungunya Virus Transmission Potential by Local Aedes Mosquitoes in the Americas and Europe (2015)

CHIKV strains belonging to the ECSA genotype could also have initiated local transmission in the new world. Additionally, the ongoing CHIKV outbreak in the Americas could potentially spread throughout Ae. aegypti- and Ae. albopictus-infested regions of the Americas with possible imported cases of CHIKV to Ae. albopictus-infested regions in Europe. Colder temperatures may decrease the local transmission of CHIKV_SM by European Ae. albopictus, potentially explaining the lack of autochthonous transmission of CHIKV_SM in Europe despite the hundreds of imported CHIKV cases returning from the Caribbean.
Analysis of Metal‐EDTA Complexes by Electrospray Mass Spectrometry (1998)

Abstract Solutions of the strong complexing agent ethylenediaminetetraacetic acid (EDTA) and Cu, Pb, Cd, Al, and Fe(III) were examined by electrospray mass spectrometry (ES/MS). Uncomplexed EDTA and metal‐EDTA complexes survive the electrospray process intact and can be detected simultaneously by mass spectrometry. Best sensitivity was achieved in the positive ion mode in which EDTA and EDTA‐metal complexes (present in solution as anions) were detected as protonated species with a single positive charge. Except for the protonation, the aqueous metal‐EDTA complexes are preserved and neither fragmentation of complexes nor formation of clusters with more than one metal or ligand were observed in the mass spectra. Detection limits are between approximately 1 to 2 µ M for uncomplexed EDTA and for the Cu‐EDTA and Pb‐EDTA complexes, with a linear range up to 10 −4 M . Calibrations based on solutions with equimolar concentrations of EDTA and Cu or Pb can be used to quantify EDTA‐metal complexes in solutions with excess EDTA or metal, and in solutions with more than one metal present. Isotopic signatures of metals in the metal‐ligand complexes are preserved, allowing the identification of the metal in a metal‐ligand complex. Isotopic signatures of metals can therefore aid in the identification of metal‐ligand complexes in unknown samples.

Conducting Polyaniline Filaments in a Mesoporous Channel Host (1994)

Conducting filaments of polyaniline have been prepared in the 3-nanometer-wide hexagonal channel system of the aluminosilicate MCM-41. Adsorption of aniline vapor into the dehydrated host, followed by reaction with peroxydisulfate, leads to encapsulated polyaniline filaments. Spectroscopic data show that the filaments are in the protonated emeraldine salt form, and chromatography indicates chain lengths of several hundred aniline rings. The filaments have significant conductivity while encapsulated in the channels, as measured by microwave absorption at 2.6 gigahertz. This demonstration of conjugated polymers with mobile charge carriers in nanometer channels represents a step toward the design of nanometer electronic devices.
Quest for Anionic MOF Membranes: Continuous sod-ZMOF Membrane with CO2 Adsorption-Driven Selectivity (2015)

We report the fabrication of the first continuous zeolite-like metal-organic framework (ZMOF) thin-film membrane. A pure phase sod-ZMOF, sodalite topology, membrane was grown and supported on a porous alumina substrate using a solvothermal crystallization method. The absence of pinhole defects in the film was confirmed and supported by the occurrence of quantifiable time-lags, for all studied gases, during constant volume/variable pressure permeation tests. For both pure and mixed gas feeds, the sod-ZMOF-1 membrane exhibits favorable permeation selectivity toward carbon dioxide over relevant industrial gases such as H2, N2, and CH4, and it is mainly governed by favorable CO2 adsorption.
Pathwise convergence rate for numerical solutions of stochastic differential equations (2011)

Devoted to numerical solutions of stochastic differential equations (SDEs), this work constructs a sequences of re-embedded numerical solutions having the same distribution as those of the original SDE in a new probability space. It is shown that the re-embedded numerical solutions converge strongly to the solution of the SDE. Moreover, the rate of convergence is ascertained. The main theorem is obtained by deriving a number of technical lemmas, that are interesting in their own right. Different from the well-known results in numerical solutions of SDEs, in lieu of the usual Brownian motion increments in the algorithm, an easily implementable sequence of independent and identically distributed (i.i.d.) random variables is used. Being easier to implement compared to the construction of Brownian increments, such an i.i.d. sequence is preferable in the actual computation. As far as the convergence and uniform mean square error estimates are concerned, the use of the i.i.d. sequence does not introduce essential difficulties compared with that of the Brownian increments. Nevertheless, the analysis becomes much more difficult in the study of rates of convergence because one has to deal with the difference of the Brownian increments and the i.i.d. sequence in the almost sure sense. This paper presents a new approach to establishing rates of convergence.
Investigating the Mechanistic and Structural Role of Lipid Hydrolysis in the Stabilization of Ammonia-Preserved Hevea Rubber Latex (2018)

The stabilization mechanism of natural rubber (NR) latex from Hevea brasiliensis was studied to investigate the components involved in base-catalyzed ester hydrolysis, namely, hydrolyzable lipids, ammonia, and the products responsible for the desired phenomenon observed in ammonia-preserved NR latex. Latex stability is generally thought to come from a rubber particle (RP) dispersion in the serum, which is encouraged by negatively charged species distributed on the RP surface. The mechanical stability time (MST) and zeta potential were measured to monitor field latices preserved in high (FNR-HA) and low ammonia (FNR-LA) contents as well as that with the ester-containing components removed (saponified NR) at different storage times. Amounts of carboxylates of free fatty acids (FFAs), which were released by the transformation and also hypothesized to be responsible for the like-charge repulsion of RPs, were measured as the higher fatty acid (HFA) number and corroborated by confocal laser scanning microscopy (CLSM) both qualitatively and quantitatively. The lipids and their FFA products interact differently with Nile red, which is a lipid-selective and polarity-sensitive fluorophore, and consequently re-emit characteristically. The results were confirmed by conventional ester content determination utilizing different solvent extraction systems to reveal that the lipids hydrolyzed to provide negatively charged fatty acid species were mainly the polar lipids (glycolipids and phospholipids) at the RP membrane but not those directly linked to the rubber molecule and, to a certain extent, those suspended in the serum. From new findings disclosed herein together with those already reported, a new model for the Hevea rubber particle in the latex form is proposed.
Retail Sweep Programs and Bank Reserves (2001)

Since January 1994, the Federal Reserve Board has permitted depository institutions in the United States to implement so-called retail sweep programs.The essence of these programs is computer software that dynamically reclassifies customer deposits between transaction accounts, which are subject to statutory reserve requirement ratios as high as 10 percent, and money market deposit accounts, which have a zero ratio.Through the use of such software, hundreds of banks have sharply reduced the amount of their required reserves.In some cases, this new level of required reserves is less than the amount that the bank requires for its ordinary, day-to-day business.In the terminology introduced by Anderson and Rasche (1996b), such deposit-sweeping activity has allowed these banks to become "economically nonbound," and has reduced to zero the economic burden ("tax") due to statutory reserve requirements.In this analysis, we examine a large panel of U.S. banks and develop quantitative estimates of the impact of sweep software programs on the demand for bank reserves.
Off-diagonal disorder in dilute metal alloys (1977)

The differences are resolved between the results of Fukuyama, Krakauer and Schwartz, and Hwang and Sher on the electronic density of states in dilute metal alloys with off-diagonal disorder retained in the Hamiltonian. This is accomplished by introducing an alternative decomposition of the alloy Hamiltonian in the Hwang and Sher formalism. The best choice for the decomposition of the Hamiltonian will be that which produces the smallest correlation corrections to the cluster coherent-potential approximation.
Construction of 3-D micro structure by multi-face FAB, co-focus rotational robot and various mechanical tools (1994)

In order to manufacture a 3-D micro structure, the following three mechanical methods are newly designed: (1) Multi-face FAB (fast atom beam): The beam, which passed through a hole of a non-contact mask, can pattern-etch on multiple faces of a workpiece by using the intermittent rotation of the workpiece. Because FAB showers straight, the pattern-etching can be performed sharply even on an undulated workpiece where a lithographic contact mask can not draw any pattern. (2) Co-focus rotational robot: The robot's hand has 4 rotational and 3 translational degrees of freedom. Because the rotation axes cross within the microscopic visual area, an operator can execute any micro 3-D task with the rotation under an all-time observation. (3) Mechanical tools: As an end-effector of micro manufacturing machines, the micro mechanical tools are inevitable. In this paper, a vibrating cutting/scraping tool and an air sucking handling tool are developed. In order to confirm the validity of the above concept and the proposed methods, a micro Gojunoto (an old Japanese temple tower, 280/spl times/100/spl times/100 /spl mu/m) was constructed as an example of the 3-D micro structure. Through this construction, it is clarified that the above methods can successfully realize the 3-D micro structure.
Analyses of the Distribution Patterns of Burkholderia pseudomallei and Associated Phages in Soil Samples in Thailand Suggest That Phage Presence Reduces the Frequency of Bacterial Isolation (2016)

The presence of podoviruses capable of infecting B. pseudomallei may affect the success of the pathogen isolation from the soil. The currently used culture-based methods of B. pseudomallei isolation appear to under-estimate the bacterial abundance. The detection of phage capable of infecting B. pseudomallei from environmental samples could be a useful preliminary test to indicate the likely presence of B. pseudomallei in environmental samples.
A Low Power Wireless Sensor Network for Gully Pot Monitoring in Urban Catchments (2011)

Sewer and gully blockages are the main cause of residential sewer flooding in the U.K. A low-cost and power efficient wireless sensor mesh networking communication system has been designed, developed and implemented to provide adequate warning on potential blockage incidents to prevent sewer failure. By monitoring the water level of the gully pot at each residential property, the water company will be proactively informed of the best course of actions to eliminate the causal problem, i.e., blockage and leakage within the sewer infrastructure. Hence, the number of residential sewer flooding and pollution incidents can be reduced. The prototype system consists of eight Zigbee based wireless sensor nodes and a GPRS enabled data gatherer. Each Zigbee sensor node comprises of a radio transceiver, a data acquisition board and an acoustic sensor probe. Field trials were carried out in an outdoor scenario to cross-validate the theoretical and practical performance of the prototype system. The results in terms of durability of sensors, sensor nodes and gateways and reliability of communication under real operational conditions and within a typical inner city urban environment are discussed. The problems encountered and solutions to tackle these problems were addressed.
Balloon Flight Demonstration of an Oscillating Heat Pipe (2017)

The oscillating heat pipe (OHP) is a novel heat-transfer technique used in thermal engineering. Although the OHP offers many technical advantages, it has not yet been actually used in the sky. Motivated by the need to develop a cooling system for use in the balloon-borne General Anti-Particle Spectrometer (GAPS) project, we are developing OHP technologies. To demonstrate the thermal performances of an OHP in real balloon flight conditions, a scaled-down OHP model was launched by a stratospheric balloon in Japan. In this study, we report the results of the flight demonstration.
Eimeria refractile body proteins contain two potentially functional characteristics: Transhydrogenase and carbohydrate transport (1993)

cDNA encoding an immunogenic protein from partially sporulated oocysts of Eimeria acervulina was cloned and used to search for the homologous counterpart in Eimeria tenella. Monospecific antibodies were raised against the recombinant expression product. Using these antibodies, the parasite proteins were found to be localised in the refractile bodies. The derived amino-acid sequences were compared by computer using the SWISSPROT protein database. In addition to high homology between the Eimeria species, extensive similarity was found with pyridine nucleotide transhydrogenase from Escherichia coli. Comparison with the sugar signature database also resulted in a possible sugar binding domain present only in the Eimeria proteins. It is possible that the corresponding parasite proteins play a role in the recently discovered mannitol cycle of Eimeria.
Fracture-Stimulation Diagnostics in Horizontal Wells Through Use of Distributed-Temperature-Sensing Technology (2012)

Summary Horizontal wells with hydraulic-fracture treatments have proved to be an effective method for developing unconventional oil and gas reservoirs. During the past several years, fracturing methods have evolved and improved rapidly; however, there still exist many uncertainties in fracture design. Several fracture-diagnostic techniques have been developed to improve the understanding of the fracturing process. In this study, after reviewing the application and limitations of the current fracture-diagnostic techniques, we describe the application of distributed-temperature-sensing (DTS) technology as a complementary tool for real-time fracture diagnostics. DTS technology has enabled us to observe the dynamic-temperature profile along the wellbore during the treatment. However, quantitative interpretation of dynamic-temperature data is very challenging and requires in-depth mathematical modeling of heat and mass transfer during the treatment. We have developed a thermal model to simulate the temperature behavior along the wellbore during the treatment, as well as during the shut-in period. This model takes into account the effect of all significant thermal processes involved, including conduction and convection. Examples are presented to illustrate how this model can be applied for fracture-stimulation diagnostics. Estimation of the fracture-initiation points, number of created fractures, and distribution of stimulation fluid along each isolated zone are the problems for which DTS technology can help obtain answers. The effectiveness of isolation can also be diagnosed by DTS technology because the heat-transfer mechanism changes when convection caused by leaking in isolation occurs. This information can be used for more-accurate fracture modeling and better estimation of fracture conductivity and fracture geometry and, therefore, to optimize future treatments and also to evaluate the well performance.
Development of a model for breast tomosynthesis image acquisition (2007)

Tomosynthesis is emerging as a promising modality for breast imaging. Several manufacturers have developed prototype units and have acquired clinical and phantom data. Scanning configurations of these prototypes vary. So far, studies relating scanning configuration to image quality have been limited to those geometries that could be implemented on a particular prototype. To overcome this limitation, we are developing a model of breast tomosynthesis image acquisition system, which models the formation of the x-ray image and x-ray detector. The x-ray image of an object is computed analytically for a polychromatic x-ray beam. Objects consist of volumetric regions that are bounded by either a planar, ellipsoidal, cylindrical or conical surface, allowing for a variety of objects. xray scatter is computed by convolving the image with a scatter point-spread function. Poisson noise according to the entrance exposure is added to the image. The x-ray detector in this model is composed of a phosphor screen followed by a detector array. X-ray interactions in the screen are modeled as depth-dependent. The optical output of the screen is converted into digital units using a gain factor which was assumed to be Gaussian distributed. To validate this data model, we acquired images of a contrast-detail phantom on a stereotactic biopsy unit. The x-ray source is mounted on an arm that pivots in a plane about the detector center. The x-ray detector consists of a Min-R type screen fiber-optically coupled to a CCD camera. To compare actual and simulated data, we compared line profiles as well as several automatically extracted image features such as contrast-to-noise ratio, contrast, area and radial gradient index. Good agreement was found between simulation and physical data, indicating that we can now use this model to explore image quality for various tomosynthesis scanning configurations.
