Dynamic analysis of soil-structure interaction shear model for beams on transversely isotropic viscoelastic soil (2022)

Dynamic response problem of the Timoshenko shear beam resting on the transversely isotropic viscoelastic foundation and subjected to a moving load is investigated. The extended Hamilton's principle is used to obtain the dynamic response equations of the beam-soil system. The corresponding partial differential equations are derived using variational principle. Using the analytical solutions, finite-element method, and central difference method, these differential equations are solved and mutually verified. The Newmark-β iterative algorithm is employed to decouple the dynamic equations of the beam-soil system. A modified two-parameter spring foundation model is used to simulate the dynamic characteristics of soil medium. Finite-element analysis demonstrates that the developed shear model of beam-soil is effective and accurate. Other numerical examples are carried out to analyze the effect of the shear beam, the load speed, and transverse isotropy of the dynamic medium model.

Universal phonon mean free path spectra in crystalline semiconductors at high temperature (2013)

Thermal conductivity in non-metallic crystalline materials results from cumulative contributions of phonons that have a broad range of mean free paths. Here we use high frequency surface temperature modulation that generates non-diffusive phonon transport to probe the phonon mean free path spectra of GaAs, GaN, AlN, and 4H-SiC at temperatures near 80 K, 150 K, 300 K, and 400 K. We find that phonons with MFPs greater than 230 ± 120 nm, 1000 ± 200 nm, 2500 ± 800 nm, and 4200 ± 850 nm contribute 50% of the bulk thermal conductivity of GaAs, GaN, AlN, and 4H-SiC near room temperature. By non-dimensionalizing the data based on Umklapp scattering rates of phonons, we identified a universal phonon mean free path spectrum in small unit cell crystalline semiconductors at high temperature.
PHOTOINHIBITION OF STIMULABLE BIOLUMINESCENCE IN MARINE DINOFLAGELLATES (1981)

Abstract— Different genera of bioluminescent photosynthetic dinoflagellates exhibit different mechanisms for the inhibition of stimulable bioluminescence during daylight. These are (a) reduction in bioluminescence capacity, (b) increased refractoriness to mechanical stimulation, and (c) inhibition of transmission of signals from mechanical receptor sites to bioluminescence emission sites. The increase in stimulable bioluminescence that in nature mirrors the decrease in sunlight intensity prior to sunset is dependent upon the logarithm of the ambient irradiation intensity. Photoinhibition of bioluminescence in all species examined except Gonyaulax polyedra is the result of absorption of light in the blue region of the spectrum.

Reduced-confinement GaAlAs tapered waveguide antennas for enhanced far-field beam directionality (1991)

Reduced-confinement tapered waveguide antennas are shown to produce reductions of >35% in the transverse far-field beam divergence for radiation emitted from GaAlAs slab waveguides, resulting in far-field beams as narrow as 8.2 degrees full width at half-maximum (FWHM) along the direction perpendicular to the wafer surface. Reduced confinement of the guided mode near the output endface is achieved using a novel molecular-beam-epitaxy growth technique to produce a longitudinal reduction in the refractive index and thickness of the waveguide film. The reduced-confinement geometry has the distinct advantage over horn antennas of being compatible with two-dimensional antenna development. A numerical simulation is used to verify and predict the performance limitations of reduced-confinement antennas. Requirements on both the amplitude and phase profiles of the electric field at the antenna output are shown to impose a stringent lower limit on the acceptable taper length for optimal antenna performance.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">&gt;</ETX>
FPGA power estimation simulator for dynamic input data (2016)

As the availability of field-programmable gate arrays (FPGAs) increases, the importance of their power management has become crucial. For an efficient power management scheme, an accurate power estimation is required. The power consumption of FPGAs differs depending on the input, and previous power estimation methods have limitations which make it difficult to predict the input patterns which affect the power consumption of FPGA. Therefore, we propose a simulator which is able to estimate the power in consideration of input data. It estimates the power consumption more accurately at a minute level. From the result of experiment, we identify that there is a great gap on power estimation between previous methods and the proposed one.

Using transit or municipal vehicles as moving observer platforms for large scale collection of traffic and transportation system information (2011)

The availability of traffic flow data on urban roads, as presently collected, is limited due to the sparse number of sensors over the spatially extensive network. We describe a prototype implementation of a sensor and data analysis system that could be deployed on transit or municipal vehicles to collect traffic flow data. It consists of a data collection vehicle with positioning sensors (GPS, IMU, and OEM vehicle state sensors) as well as multiple ranging sensors to monitor the ambient traffic (vertical LiDAR). Our premise is that some data on a given link is better than the current situation where most links go unobserved. The system is capable of detecting vehicles over multiple lanes, providing velocity and shape-based vehicle classification for each vehicle. We also present the results of several validation experiments, comparing the detection system against concurrent ground truth data.
Rhodium‐Catalyzed [4+2] Annulation of N‐Aryl Pyrazolones with Diazo Compounds To Access Pyrazolone‐Fused Cinnolines (2021)

Abstract An efficient synthesis of novel dinitrogen‐fused heterocycles such as pyrazolo[1,2‐ a ]cinnoline derivatives have been accomplished by the rhodium(III)‐catalyzed reaction of N ‐arylpyrazol‐5‐ones with α ‐diazo compounds. This reaction proceeds through a cascade C−H activation/intramolecular cyclization with a broad substrate scope. Furthermore, this protocol is successfully extended to the unusual phosphorus‐containing α ‐diazo compounds and cyclic diazo compounds as the cross‐coupling partners to deliver the two new kinds of pyrazolo[1,2‐ a ]cinnolinones. The control experiments were performed to reveal insight into the mechanism of this reaction, involving reversible C−H activation, migratory insertion of the diazo compound, and cascade cyclization as the key steps of the transformation. Moreover, gram‐scale synthesis and further transformation of the target product demonstrate the synthetic utility of the present protocol.
Modeling spin injection across diffuse interfaces (2013)

We propose a model of the injection of spin-polarized current in systems with diffuse interfaces. The effect of the interfaces between a ferromagnet and a nonmagnet and between two ferromagnets on spin injection is investigated. We first generalize the formalism for calculating the spin accumulation by taking the spin accumulation as the difference of spin-up and spin-down density of states, which is necessary for treating the interface between different ferromagnets. Then, we include the effect of atomic species interdiffusion at the interface by using Fick's law. It is shown that the discontinuity of the spin accumulation at the interface depends strongly on the degree of interface mixing.

Performance of 8$\,\times\,$8 Pixel LaBr$_{3}$:Ce and Gd$_{2}$SiO$_{5}$:Ce Scintillator Arrays Coupled to a 64-Channel Multi-Anode PMT (2009)

We have developed a LaBr <sub xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">3</sub> :Ce scintillator array consisting of 8 × 8 pixels with a size of 5.8 mm×5.8 mm×15.0 mm, which serves as an absorber of scattered gamma rays with energies from 0.1 to 1 MeV in a Compton camera. The pixels were cut from two pieces of LaBr <sub xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">3</sub> :Ce crystal with a diameter of 38 mm and a length of 38 mm with full width at half-maximum (FWHM) energy resolutions of 4.1 ± 0.1% and 3.0 ± 0.1% at 356 and 662 keV, respectively, measured with a single anode photomultiplier tube (PMT). The crystal had the following volumetric uniformities: light outputs with a difference of 0.5% (standard deviation: SD) and energy resolutions with that of 2% (SD) at 356 keV. In contrast, for each pixel in the array, the average and SD FWHM energy resolutions over 64 pixels, measured with a single-anode PMT and a collimator, were 5.8 ± 0.9% at 356 keV. The array was then coupled to a 64-channel multi-anode PMT (Hamamatsu H8500), the anode pitch of which was the same as the LaBr <sub xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">3</sub> :Ce pixel pitch of 6.1 mm. When the 64 anodes were read out from four channels in a resistor chain by the charge division method, the FWHM energy resolution of all 64 pixels was 7.0 ± 0.5% at 662 keV, whereas that of the inner 6×6 pixels was 5.8 ± 0.4% at 662 keV. In addition, we measured a Gd <sub xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">2</sub> SiO <sub xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">5</sub> :Ce (GSO:Ce) scintillator array consisting of 8×8 pixels with a size of 5.9 mm×5.9 mm×13.0 mm to compare its performance with that of the LaBr <sub xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">3</sub> :Ce array. The FWHM energy resolution of all 64 GSO:Ce pixels was 10.8 ± 0.3% at 662 keV. With these energy resolutions, FWHM angular resolutions of the Compton camera using the LaBr <sub xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">3</sub> :Ce and GSO:Ce arrays are expected to be 4.6° and 5.3°, respectively, at 662 keV.
Influence of Using Metallic Na on the Interfacial and Transport Properties of Na-Ion Batteries (2017)

Na2Ti3O7 is a promising negative electrode for rechargeable Na-ion batteries; however, its good properties in terms of insertion voltage and specific capacity are hampered by the poor capacity retention reported in the past. The interfacial and ionic/electronic properties are key factors to understanding the electrochemical performance of Na2Ti3O7. Therefore, its study is of utmost importance. In addition, although rather unexplored, the use of metallic Na in half-cell studies is another important issue due to the fact that side-reactions will be induced when metallic Na is in contact with the electrolyte. Hence, in this work the interfacial and transport properties of full Na-ion cells have been investigated and compared with half-cells upon electrochemical cycling by means of X-ray photoelectron spectroscopy (conventional XPS and Auger parameter analysis) and electrochemical impedance spectroscopy. The half-cell has been assembled with C-coated Na2Ti3O7 against metallic Na whilst the full-cell uses C-coated Na2Ti3O7 as negative electrode and NaFePO4 as positive electrode, delivering 112 Wh/kganode+cathode in the 2nd cycle. When comparing both types of cells, it has been found that the interfacial properties, the OCV (open circuit voltage) and the electrode–-electrolyte interphase behavior are more stable in the full-cell than in the half-cell. The electronic transition from insulator to conductor previously observed in a half-cell for Na2Ti3O7 has also been detected in the full-cell impedance analysis.
The rapid, living, anionic polymerization of 2‐vinylnaphthalene at ambient temperature: Characterization of an n‐butyllithium/tetrahydrofuran system in 1,2,3,4‐tetrahydronaphthalene (2015)

ABSTRACT We report the first well‐controlled room temperature anionic polymerization of 2‐vinylnaphthalene (2‐VNP), using alkyllithium (RLi) initiators. The nucleophilicity and solubility of the RLi as well as that of the 2‐vinylnaphthalenyllithium (VNPLi) and poly(2‐vinylnaphthalenyl)lithium (PVNPLi) propagating species were found to be very important factors in this reaction. An initiator system composed of n ‐butyllithium ( n ‐BuLi) with tetrahydrofuran (THF) in 1,2,3,4‐tetrahydronaphthalene (THN) was determined to be the most effective of the various systems examined. The n ‐BuLi/THF complex initiates polymerization and the resulting VNPLi/THF and PVNPLi/THF complexes act as propagating species at room temperature. These species offer adequate nucleophilicity and stability without promoting side reactions. As a result, rapid anionic polymerization was achieved. Various poly(2‐VNP) products with well‐defined polymeric chain structures were synthesized by this process at room temperature. © 2015 Wiley Periodicals, Inc. J. Appl. Polym. Sci. 2015 , 132 , 41901.
A comparison between p<sup>+</sup>n and n<sup>+</sup>p GaAs displacement damage coefficients following proton irradiation (2008)

In this paper, the photovoltaic response of p <sup xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">+</sup> n and n <sup xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">+</sup> p GaAs solar cells is monitored as a function of proton fluence at different proton energies. The energy dependence of displacement damage coefficients (DCs) describing the photovoltaic degradation for these devices are compared with calculations of nonionizing energy loss (NIEL). The short circuit current DCs for both device types follows the same energy dependence. In contrast, the open circuit voltage DCs follows a different energy dependence at higher proton energies (E ≫ 10 MeV).

BindingDB Entry 5200: Nitrocinnamoyl and chlorocinnamoyl derivatives of dihydrocodeinone: in vivo and in vitro characterization of mu-selective agonist and antagonist activity. (2012)

Two 14beta-p-nitrocinnamoyl derivatives of dihydrocodeinone, 14beta-(p-nitrocinnamoylamino)-7,8-dihydrocodeinone (CACO) and N-cyclopropylmethylnor-14beta-(p-nitrocinnamoylamino)- 7, 8-dihydrocodeinone (N-CPM-CACO), and the corresponding chlorocinnamoylamino analogs, 14beta-(p-chlorocinnamoylamino)-7, 8-dihydrocodeinone (CAM) and N-cyclopropylmethylnor-14beta-(p-chlorocinnamoylamino) -7, 8-dihydrocodeinone (MC-CAM), were tested in opioid receptor binding assays and the mouse tail-flick test to characterize the opioid affinity, selectivity, and antinociceptive properties of these compounds. In competition binding assays, all four compounds bound to the mu opioid receptor with high affinity. When bovine striatal membranes were incubated with any of the four dihydrocodeinones, binding to the mu receptor was inhibited in a concentration-dependent, wash-resistant manner. Saturation binding experiments demonstrated that the wash-resistant inhibition of mu binding was due to a decrease in the Bmax value for the binding of the mu-selective peptide [3H][D-Ala2, MePhe4,Gly(ol)5] enkephalin and not a change in the Kd value, suggesting an irreversible interaction of the compounds with the mu receptor. In the mouse 55 degrees C warm water tail-flick test, both CACO and N-CPM-CACO acted as short-term mu-selective agonists when administered by i. c.v. injection, whereas CAM and MC-CAM produced no measurable antinociception at doses up to 30 nmol. Pretreatment of mice for 24 h with any of the four dihydrocodeinone derivatives produced a dose-dependent antagonism of antinociception mediated by the mu but not the delta or kappa receptors. Long-term antagonism of morphine-induced antinociception lasted for at least 48 h after i.c. v. administration. Finally, shifts in the morphine dose-response lines after 24-h pretreatment with the four dihydrocodeinone compounds suggest that the nitrocinnamoylamino derivatives may produce a greater magnitude long-term antagonism of morphine-induced antinociception than the chlorocinnamoylamino analogs.
Influence of coenzyme A-independent transacylase and cyclooxygenase inhibitors on the proliferation of breast cancer cells. (1999)

Recent studies have demonstrated that arachidonic acid (AA) may serve as an important signal that blocks cell proliferation of certain neoplastic cells. The current study was conducted to determine whether disruption of AA homeostasis influences breast cancer cell proliferation and death. Initial experiments revealed that inhibition of AA remodeling through membrane phospholipids by inhibitors of the enzyme, coenzyme A-independent transacylase (CoA-IT), attenuates the proliferation of the estrogen receptor-negative, MDA-MB-231, and estrogen receptor-positive, MCF-7 breast cancer cell lines. This growth inhibition was accompanied by a marked accumulation of AA in both free fatty acid and triglyceride forms, a marker of intracellular AA stress within mammalian cells. Cell cycle synchronization experiments revealed that the CoA-IT inhibitor, SB-98625, blocked MDA-MB-231 cell replication in early to mid G1 phase. Time-lapse video microscopy, used to observe the changes in cell morphology associated with apoptosis, indicated that SB-98625 treatment induced early rounding and occasional blebbing but not late apoptotic events, blistering, and lysis. The cyclooxygenase inhibitors, NS-398 and indomethacin, were found to be less potent blockers of cell proliferation and poor inducers of cellular AA accumulation than CoA-IT inhibitors in these breast cancer cell lines. Finally, AA provided exogenously blocked the proliferation of MCF-7 cells, and this effect could be attenuated in MCF-7 cells overexpressing the glutathione peroxidase gene, GSHPx-1. Taken together, these experiments suggest that disruption of AA remodeling in a manner that increases intracellular AA may represent a novel therapeutic strategy to reduce cancer cell proliferation and that an oxidized AA metabolite is likely to mediate this effect.
Circulating anti‐retinal antibodies in response to anti‐angiogenic therapy in exudative age‐related macular degeneration (2014)

Changes in serum ARAs levels occurred in parallel with clinical outcomes of anti-VEGF therapy. Treatment reduced serum levels of ARAs, with the greatest reduction occurring during the 'loading' phase. This study demonstrated that ARAs may act as a serum biomarker of the efficacy of anti-VEGF therapy.

Genetic variation of glycoproteins B and H of human herpesvirus 7 in Hong Kong (2003)

Glycoprotein B (gB) and glycoprotein H (gH) of human herpesvirus 7 (HHV-7) are believed to play an important role in virus entry and as targets for host immune response. This study examined the genetic diversity of these glycoproteins among 90 HHV-7 isolates collected from different individuals in Hong Kong. Overall, both the gB and gH genes were found to be highly conserved. Nucleotide polymorphism was detected only at four positions of the gB-encoding region, and all of these were synonymous substitutions. Most (97.8%) Hong Kong isolates were of gB allele group C. Two isolates collected from a Pakistani family showed a novel sequence pattern that did not match known gB allele groups. This sequence pattern was detected consistently from serial samples collected from the same individual, indicating a stable genetic entity. The gH-encoding region exhibited nucleotide polymorphism at six positions. Three of these were nonsynonymous substitutions (codon 271 Lys --> Gln, codon 308 Gly --> Glu, codon 397 Asn --> Tyr). Most (84.4%) Hong Kong isolates were of the gH allele group B, and all others were of the gH allele group C. These data indicate the possibility of using gB or gH alleles as markers for studying world-wide population movements and genetics.
Silage review: Recent advances and future technologies for whole-plant and fractionated corn silage harvesting (2018)

Over the last 25 years, whole-plant corn silage has become an important and popular feedstuff for dairy production. Copious research has been dedicated to the development and evaluation of alternatives to enhance the nutritive value of whole-plant corn silage. These efforts have been aimed at manipulating the physical and chemical characteristics of whole-plant corn silage in an effort to maximize dairy profitability. Results from this review indicate that optimization of harvest maturity, kernel processing, theoretical length of cut, and cutting height improve or maintain the nutritive value and milk production of lactating dairy cows. Technological advancements have been developed and made available to dairy producers and corn growers desiring to enhance fiber and starch digestibility of whole-plant corn silage. Future research should be directed toward further assessment of new processors available in the market and the development of assessment methods for optimization of crop processor settings, harvest efficiency, and nutritional modeling.
