Low-temperature synthesis of K0.5FeF3 with tunable exchange bias (2013)

Fluorides K0.5FeF3 with tetragonal tungsten bronze structure have been fabricated by solid state reaction at low sintering temperature in the range between 150 °C and 400 °C with the assistance of crystal water during the grinding and sintering processes. Unusual magnetic properties have been observed, including positive exchange bias field (HE) with negative vertical magnetization shift (Mshift), and smaller field cooling (FC) magnetization than the zero field cooling one below 53 K. The results are explained by a core-shell structure consisting of antiferromagnetic core and spin glass (SG) shell with antiferromagnetic interfacial coupling between the pinned interface spins and the SG shell spins. The sign of HE and Mshift can be changed by increasing the cooling field in the FC process, which is attributed to the competition between the antiferromagnetic interfacial coupling and the Zeeman energy of magnetization of the SG shell.
Isolation and Characterization of Mutations in Bacillus subtilis That Allow Spore Germination in the Novel Germinant d -Alanine (1999)

Bacillus subtilis spores break their metabolic dormancy through a process called germination. Spore germination is triggered by specific molecules called germinants, which are thought to act by binding to and stimulating spore receptors. Three homologous operons, gerA, gerB, and gerK, were previously proposed to encode germinant receptors because inactivating mutations in those genes confer a germinant-specific defect in germination. To more definitely identify genes that encode germinant receptors, we isolated mutants whose spores germinated in the novel germinant D-alanine, because such mutants would likely contain gain-of-function mutations in genes that encoded preexisting germinant receptors. Three independent mutants were isolated, and in each case the mutant phenotype was shown to result from a single dominant mutation in the gerB operon. Two of the mutations altered the gerBA gene, whereas the third affected the gerBB gene. These results suggest that gerBA and gerBB encode components of the germinant receptor. Furthermore, genetic interactions between the wild-type gerB and the mutant gerBA and gerBB alleles suggested that the germinant receptor might be a complex containing GerBA, GerBB, and probably other proteins. Thus, we propose that the gerB operon encodes at least two components of a multicomponent germinant receptor.
An OC-768 transponder for 40 and 43 Gb/s short-reach links (2003)

This presentation will review several aspects of an OC-768 transponder that has been successfully implemented for data rates of 40 to 43 Gb/s. The high-level operation is described, as well as selected details of a chipset designed specifically for this transponder. Measurements demonstrate that the performance has significant built-in margin and is suitable for long-term operation over short-reach OC-768 fiber links.
Strain-Induced Spin-Nematic State and Nematic Susceptibility Arising from 2×2 Fe Clusters in KFe0.8Ag1.2Te2 (2019)

Spin nematics break spin-rotational symmetry while maintaining time-reversal symmetry, analogous to liquid crystal nematics that break spatial rotational symmetry while maintaining translational symmetry. Although several candidate spin nematics have been proposed, the identification and characterization of such a state remain challenging because the spin-nematic order parameter does not couple directly to experimental probes. KFe_{0.8}Ag_{1.2}Te_{2} (K_{5}Fe_{4}Ag_{6}Te_{10}, KFAT) is a local-moment magnet consisting of well-separated 2×2 Fe clusters, and in its ground state the clusters order magnetically, breaking both spin-rotational and time-reversal symmetries. Using uniform magnetic susceptibility and neutron scattering measurements, we find a small strain induces sizable spin anisotropy in the paramagnetic state of KFAT, manifestly breaking spin-rotational symmetry while retaining time-reversal symmetry, resulting in a strain-induced spin-nematic state in which the 2×2 clusters act as the spin analog of molecules in a liquid crystal nematic. The strain-induced spin anisotropy in KFAT allows us to probe its nematic susceptibility, revealing a divergentlike increase upon cooling, indicating the ordered ground state is driven by a spin-orbital entangled nematic order parameter.
Mixed micellisation of oxyethylene–oxybutylene diblock and triblock copolymers in water studied by light scattering (2002)

The mixed micellisation of copolymers E60B12 and E58B20E58 in water was investigated using static and dynamic light scattering (SLS and DLS). As expected, considering the similarity of their E block lengths, the radii of the micelles were constant irrespective of the proportions of the two copolymers in solution. Micelle association numbers, which differed for the two copolymers when micellised singly, depended on the proportions of the two copolymers in solution. This dependence was rationalised by taking account of the triblock copolymer looping in the micelle. The mixed micelles were found to have a harder intermicellar interaction potential than those formed from the single copolymers.
Incorporating Hole Cold Expansion to Meet Durability and Damage Tolerance Airworthiness Objectives (1997)

&lt;div class="htmlview paragraph"&gt;Aircraft structural integrity requirements now embrace damage tolerance requirements as the basis for design and continued safe operation. The challenge facing industry is how to economically achieve these requirements in both new and, to a greater extent, the growing volume of aging aircraft. Compensating for damage tolerance analysis could lead to overweight structures. Not allowing for residual cracks in repairs could compromise the long term structural integrity, induce on-going inspection penalties and possibly result in unnecessary major structural replacement or repair. Hole cold expansion is a proven method for retarding the growth of cracks originating in holes. This paper discusses the technology and the effectiveness of the induced residual compressive stresses in reducing the stress intensity factor and permitting the use of smaller initial flaw sizes to meet damage tolerance requirements. Some ideas are presented on how practical results and applications can be used to incorporate these benefits in analysis to extend fatigue life and provide terminating repair action in repairs.&lt;/div&gt;
Nucleotides at the extremities of the viral RNA of influenza C virus are involved in type-specific interactions with the polymerase complex (2001)

Influenza A and C viruses share common sequences in the terminal noncoding regions of the viral RNA segments. Differences at the 5'- and 3'-ends exist, however, that could contribute to the specificity with which the transcription/replication signals are recognized by the cognate polymerase complexes. Previously, by making use of a transient expression system for the transcription and replication of a reporter RNA template bearing either type A or type C extremities, it was shown that a type C RNA template is transcribed and replicated with equal efficiency by either the type A or the type C polymerase complex, whereas a type A RNA template is less efficiently transcribed and replicated by the type C polymerase complex than by the type A complex. To explore the contribution of the nucleotides at the extremities of the RNAs to this type-specificity, the effect of mutations introduced either alone or in combination at nucleotide 5 at the 3'-end and at nucleotides 3', 6' or 8' at the 5'-end of type A or C RNA templates were studied in the presence of either the type A or the type C polymerase complex. The results indicate that the nature of nucleotides 5 and 6' contribute to type-specificity. Moreover, these results underline the importance of the base pairing between nucleotide 3' and 8' at the 5'-end of the RNA. Thus, it could be suggested that the nature of the nucleotides as well as the stability of the secondary structure at the extremities of the viral RNA are important determinants of type-specificity.
RNA-Seq Based Transcriptome Analysis of the Type I Interferon Host Response upon Vaccinia Virus Infection of Mouse Cells (2017)

Vaccinia virus (VACV) encodes the soluble type I interferon (IFN) binding protein B18 that is secreted from infected cells and also attaches to the cell surface, as an immunomodulatory strategy to inhibit the host IFN response. By using next generation sequencing technologies, we performed a detailed RNA-seq study to dissect at the transcriptional level the modulation of the IFN based host response by VACV and B18. Transcriptome profiling of L929 cells after incubation with purified recombinant B18 protein showed that attachment of B18 to the cell surface does not trigger cell signalling leading to transcriptional activation. Consistent with its ability to bind type I IFN, B18 completely inhibited the IFN-mediated modulation of host gene expression. Addition of UV-inactivated virus particles to cell cultures altered the expression of a set of 53 cellular genes, including genes involved in innate immunity. Differential gene expression analyses of cells infected with replication competent VACV identified the activation of a broad range of host genes involved in multiple cellular pathways. Interestingly, we did not detect an IFN-mediated response among the transcriptional changes induced by VACV, even after the addition of IFN to cells infected with a mutant VACV lacking B18. This is consistent with additional viral mechanisms acting at different levels to block IFN responses during VACV infection.

Prognostic significance of cytosolic phospholipase A2 expression in patients with colorectal cancer (2011)

These results suggest that cPLA2 expression was not associated with the prognosis of CRC. However, further large-scale studies are needed to clarify the prognostic effect of cPLA2 in CRC.
Spectrum management in cognitive radio networks (2008)

Today’s wireless networks are characterized by a fixed spectrum assignment policy. However, a large portion of the assigned spectrum is used sporadically and geographical variations in the utilization of assigned spectrum ranges from 15% to 85% with a high variance in time. The limited available spectrum and the inefficiency in the spectrum usage necessitate a new communication paradigm to exploit the existing wireless spectrum opportunistically. This new networking paradigm is referred to as cognitive radio networks. In this talk, the novel functionalities and current research challenges of the cognitive radio networks are explained in detail. More specifically, an overview of the cognitive radio technology is provided and the network architecture is introduced. Moreover, the cognitive network functions such as spectrum management, spectrum mobility and spectrum sharing are explained in detail. The influence of these functions on the performance of the upper layer protocols such as routing and transport are investigated. Moreover, the network management, operation and maintenance problems are highlighted and open research issues in these areas are also outlined.
Swainsonine-Containing Plants and Their Relationship to Endophytic Fungi (2014)

Swainsonine, an indolizidine alkaloid with significant physiological activity, is an α-mannosidase and mannosidase II inhibitor that alters glycoprotein processing and causes lysosomal storage disease. Swainsonine is present in a number of plant species worldwide and causes severe toxicosis in livestock grazing these plants. Consumption of these plants by grazing animals leads to a chronic wasting disease characterized by weight loss, depression, altered behavior, decreased libido, infertility, and death. This review focuses on the three plant families and the associated taxa that contain swainsonine; the fungi that produce swainsonine, specifically the fungal endophytes associated with swainsonine-containing taxa; studies investigating the plant, endophyte, and swainsonine relationship; the influence of environmental factors on swainsonine concentrations in planta; and areas of future research.
HYDRODYNAMICS, MIXING AND MASS TRANSFER IN A LARGE DIAMETER JET BUBBLE COLUMN (1995)

Abstract Experimental measurements for the axial and radial variations in gas holdup, axial and radial dispersion coefficients, volumetric gas-liquid mass transfer coefficient and liquid phase circulation velocity in a cone of a large diameter (122 cm) jet bubble column are presented. Two diameters of the inlet nozzle, namely 10.16 cm and 15.24 cm, three superficial gas velocities (based on cylinder diameter), 3 cm/sec, 6 cm/sec and 8 cm/sec and two superficial liquid velocities, 0.3 cm/sec and 0.6 cm/sec, are examined. The experimental data are obtained for two different bed heights. The experimental data showed significant axial and radial variations in the gas holdup. The volumetric average gas holdup was higher at higher gas velocity and larger nozzle diameter and somewhat higher at lower liquid velocity. The axial dispersion was high while the radial dispersion was low. The volumetric gas-liquid mass transfer coefficient was larger at higher gas velocity and larger nozzle diameter. The liquid recirculation begins only at the upper end of the cone. In general, experimental data indicate that a jet bubble column provides a high degree of mixing and transport rates.

Wavelength, dose, skin type and skin model related radical formation in skin (2021)

The exposure to sun radiation is indispensable to our health; however, a long-term and high exposure could lead to cell damage, erythema, premature skin aging, and promotion of skin tumors. An underlying pathomechanism is the formation of free radicals which may induce oxidative stress at elevated concentrations. Different skin models, such as porcine-, murine-, human- ex vivo skin, reconstructed human skin (RHS) and human skin in vivo, were investigated during and after irradiation using X- and L-band EPR spectroscopy within different spectral regions (UVC to NIR). The amount of radical formation was quantified with the spin probe PCA and the radical types were measured ex vivo with the spin trap DMPO. The radiation dose influences the types of radicals formed in the skin. While reactive oxygen species (ROS) are always pronounced at low doses, there is an increase in lipid oxygen species (LOS) at high doses. Furthermore, the radical types arise independent from the irradiation wavelength, whereas the general amount of radical formation differs with the irradiation wavelength. Heat pre-stressed porcine skin already starts with higher LOS values. Thus, the radical type ratio might be an indicator of stress and the reversal of ROS/LOS constitutes the point where positive stress turns into negative stress.Compared to light skin types, darker types produce less radicals in the ultraviolet, similar amounts in the visible and higher ones in the infrared spectral region, rendering skin type-specific sun protection a necessity.

PULSE LASER INSTRUMENTATION (1965)

Abstract : The development of the techniques and devices used to measure pulse laser output at the Air Force Weapons Laboratory is described. Included are discussions of principles, physical design, associated circuitry, and impedance- matching techniques. The instrumentation system consists of a total beam calorimeter suited to the laser energy range and an integrator whose signal is correlated to the calorimeter measurement. The calorimeter is either an absorbing surface or volume arranged so that the energy is well trapped. The surface absorber is a thermally isolated hollow silver sphere whose inner surface has been highly polished and whose heat capacity can be accurately calculated. The laser beam is admitted into the sphere at the focal point of a short-focal-length lens through a very small hole off center of the sphere. The volume absorber is cone-shaped as a result of various requirements and considerations. Thermistors or thermocouples are used to measure the resultant temperature rise. The use of these devices has several merits, chiefly high accuracy, stability, and relative simplicity. In addition, the devices lend themselves to the measurement of a wide range of energy densities; e.g., by variation of the diameter of the sphere in the first mentioned device. An entirely impedance-matched circuit was designed for the high-speed light- sampling diode. Several integration techniques were considered and three were selected; the one utilized depended on the experimental situation.
Broadband Meta‐Absorber with Au/Ni Core–Shell Nanowires for Solar Vapor Generator (2021)

Abstract Solar energy has the advantages of being eco‐friendly, practically infinite, and nonreliant on chemical fuels. A solar vapor generator uses sunlight to transform a liquid stream into a vapor stream to operate a turbine for generating electricity. For efficient vapor generation, it should absorb the sunlight in broad spectrum with high absorption, and also have high photothermal conversion efficiency. In this work, Ni nanowires and Au/Ni core–shell nanowire absorbers which meet the relevant conditions are fabricated using a cost‐effective process for efficient solar vapor generation. The light is scattered and trapped in the nanowires and the electrical field is enhanced between the nanowires by the surface plasmonic gap resonance, resulting in high absorption. Also, the adiabatic nanofocusing structure generates heat at hot spots, resulting in efficient photothermal conversion. As a result, the Ni and Au/Ni core–shell nanowire absorbers respectively, absorb over 98% and 91% of the incident light in the solar spectrum. Further, the efficiency of photothermal conversion of the Au–Ni absorber under 1 Sun is found to be ≈33%. These absorbers have the potential to be applied to diverse fields, such as desalination, solar thermophotovoltaics, and metamaterials.

Proxy Model Based on Artificial Intelligence Technique for History Matching - Application to Brugge Field (2019)

Abstract History matching of production data is a process requiring a large number of reservoir simulations that are huge time-consuming. To reduce the computation time, an approach consists of using a meta-model to replace the reservoir simulator. In this paper, a proxy model based on an artificial intelligence technique (artificial neural network) is evaluated and compared to proxy models conventionally used for history matching such as polynomials or kriging methods. The proposed approach provides accurate prediction results to speed up and improve the history matching process. An application to the Brugge field is presented.

A method of simultaneous location and mapping based on RGB-D cameras (2016)

Autonomous UAV must rely on the navigation system to fly in the indoor environment. However, the traditional navigation system such as GPS cannot be used in the indoor environment. A method of Simultaneous Location and Mapping (SLAM) based on RGB-D cameras is used to solve this matter. We adopt the RGB-D SLAM algorithm to locate the camera and build the 3D map of the environment in this paper. The framework and process of the algorithm are described in detail. The experiments show that the RGB-D SLAM algorithm can achieve good results.
