The effect of river flow velocity distribution on indications of the occurrence of degradation of the Tambong River basin (2020)

Abstract Floods that have high flow velocity can be indicated that there is degradation in the riverbed. If the deterioration of the riverbed is allowed to continue, it can cause damage to the existing building infrastructure around the river. Tambong River, located in the Kabat District of Banyuwangi, has experienced river overflowing. Process of measuring flow velocity uses the current meter. To determine the shape and contour of the Tambong River flow velocity distribution using the Surfer Software. In the Tambong River basin, the middle river of the downstream has the highest river flow velocity distribution of 0.92 m/sec, with a discharge of 1.75 m 3 /sec. It was indicated that the Tambong River Basin in the middle of the downstream would experience river bed degradation by showing a Reynold of 426, 997.33 and a Froude value of 0.55 so that it includes turbulent flow types and flow types subcritical. Average flow velocity distribution in the middle of the Tambong River basin is 0.901 m/sec and was indicated to have degraded as thick as 2.10 m/year. It can be concluded that the middle part of the Tambong river is a flood-prone zone due to the considerable velocity of the river flow.
S814 and S815 Airfoils: October 1991--July 1992 (2004)

Two thick laminar-flow airfoils for the root portion of a horizontal-axis wind turbine blade, the S814 and S815, have been designed and analyzed theoretically. For both airfoils, the primary objectives of high maximum lift, insensitive to roughness, and low profile drag have been achieved. The constraints on pitching moment and airfoil thicknesses have been satisfied.

Phosphoregulation of Tau modulates inhibition of kinesin-1 motility (2017)

Microtubule-based axonal transport is tightly regulated by numerous pathways, ensuring appropriate delivery of specific organelle cargoes to selected subcellular domains. Highlighting the importance of this process, pathological evidence has linked alterations in these pathways to the pathogenesis of several neurodegenerative diseases. An important regulator of this system, the microtubule-associated protein Tau, has been shown to participate in signaling cascades, modulate microtubule dynamics, and preferentially inhibit kinesin-1 motility. However, the cellular means of regulating Tau's inhibition of kinesin-1 motility remains unknown. Tau is subject to various posttranslational modifications, including phosphorylation, but whether phosphorylation regulates Tau on the microtubule surface has not been addressed. It has been shown that tyrosine 18 phosphorylated Tau regulates inhibition of axonal transport in the disease state. Tyrosine 18 is both a disease- and nondisease-state modification and is therefore an attractive starting point for understanding control of Tau's inhibition of kinesin-1 motility. We show that pseudophosphorylation of tyrosine 18 reduces 3RS-Tau's inhibition of kinesin-1 motility. In addition, we show that introduction of negative charge at tyrosine 18 shifts Tau's previously described static-dynamic state binding equilibrium toward the dynamic state. We also present the first evidence of Tau's static-dynamic state equilibrium under physiological conditions.
Novel Peptide Chemistry in Terrestrial Animals: Natural Luciferin Analogues from the Bioluminescent Earthworm Fridericia heliota (2015)

We report isolation and structure elucidation of AsLn5, AsLn7, AsLn11 and AsLn12: novel luciferin analogs from the bioluminescent earthworm Fridericia heliota. They were found to be highly unusual modified peptides, comprising either of the two tyrosine-derived chromophores, CompX or CompY and a set of amino acids, including threonine, gamma-aminobutyric acid, homoarginine, and unsymmetrical N,N-dimethylarginine. These natural compounds represent a unique peptide chemistry found in terrestrial animals and rise novel questions concerning their biosynthetic origin.

Large-Area, Crosstalk-Free, Flexible Tactile Sensor Matrix Pixelated by Mesh Layers (2021)

Tactile sensor arrays have attracted considerable attention for their use in diverse applications, such as advanced robotics and interactive human-machine interfaces. However, conventional tactile sensor arrays suffer from electrical crosstalk caused by current leakages between the tactile cells. The approaches that have been proposed thus far to overcome this issue require complex rectifier circuits or a serial fabrication process. This article reports a flexible tactile sensor array fabricated through a batch process using a mesh. A carbon nanotube-polydimethylsiloxane composite is used to form an array of sensing cells in the mesh through a simple "dip-coating" process and is cured into a concave shape. The contact area between the electrode and the composite changes significantly under pressure, resulting in an excellent sensitivity (5.61 kPa<sup>-1</sup>) over a wide range of pressure up to 600 kPa. The mesh separates the composite into the arranged sensing cells to prevent the electrical connection between adjacent cells and simultaneously connects each cell mechanically. Additionally, the sensor shows superior durability compared with previously reported tactile sensors because the mesh acts as a support beam. Furthermore, the tactile sensor array is successfully utilized as a Braille reader via information processing based on machine learning.
Asymptotically limitless quantum energy teleportation via qudit probes (2016)

We propose a modified quantum energy teleportation scheme that uses arbitrary-dimensional qudit probes and polynomially localized Hamiltonians. We find that with an appropriate scaling of parameters, the teleported energy scales with the teleportation distance more favorably than the nonlocal tails of the Hamiltonians. We show that by allowing the exchange of arbitrary amounts of information between agents and in a suitable limit, an arbitrarily large amount of energy can be teleported through a massless quantum field.

Periodic and solitary waves on thin, horizontal, gas-sheared liquid films (1988)

Measurements of wavelengths and speeds of periodic waves which occur at the interface of thin, horizontal, liquid films sheared by a cocurrent gas flow are compared with predictions of linear theory. In general, linear predictions accurately match the data near the point of neutral stability but begin to deviate as the gas velocity increases. The behavior away from neutral stability is explained by the examination of the dynamical system associated with steady solutions to a nonlinear wave equation based on boundary-layer approximations. Periodic waves are seen to occur in the neighborhood of the Hopf curve which serves as a boundary between periodic waves and a flat film. Solitary waves (which correspond under some circumstances to disturbance or roll waves) are observed to lie in another region of parameter space at gas velocities well above neutral stability. These results suggest that a complete nonlinear analysis of the boundary-layer (or associated wave) equations would be useful for predicting amplitudes and speeds for periodic waves and the regions of occurrence for solitary waves. 38 refs., 10 figs.
Stabilized Alpha‐ MnO2 Electrodes for Rechargeable 3 V Lithium Batteries (1997)

Manganese dioxide electrodes that have x-ray diffraction patterns characteristic of α-MnO2 (hollandite-type structure) and ramsdellite-MnO2 have been evaluated in rechargeable 3 V lithium cells. Electrochemical data indicate that these electrodes (162 mAh/g, 10th cycle) provide superior performance to both single-phase pure α-MnO2 (136 mAh/g, 10th cycle) and ramsdellite-MnO2 electrodes (113 mAh/g, 10th cycle), and comparable performance to lithia-stabilized α-MnO2 (0.15Li2O · MnO2) electrodes (153 mAh/g, 10th cycle). Transmission electron microscopy images and convergent-beam electron diffraction patterns show that the MnO2 samples consist of grains of α-MnO2 grains of ramsdellite-MnO2, and grains of "interconnected" α-MnO2 and ramsdellite-MnO2 which exhibit a mutual crystallographic orientation. A search is underway to find other interconnected MnO2 materials with even better cycling performance.
A Mixed Green Vegetable and Fruit Beverage Decreased the Serum Level of Low-Density Lipoprotein Cholesterol in Hypercholesterolemic Patients (2002)

The effects of a canned mixed green vegetable and fruit beverage, containing broccoli (Brassica oleracea L. var. botrytis L.) and cabbage (Brassica oleracea L. var. capitata L.) as main materials, on serum lipid levels in hypercholesterolemic patients were investigated. Thirty-one adult subjects were administered two cans of the beverage (160 g/can) per day for 3 weeks. Their serum total cholesterol (TC) levels significantly decreased from 6.7 +/- 0.8 to 6.1 +/- 0.6 mmol/L, and, more strikingly, the level of low-density lipoprotein cholesterol (LDL-C) significantly decreased from 4.4 +/- 0.8 to 3.8 +/- 0.7 mmol/L. At 9 weeks after the cessation of the administration, these levels had returned to the preadministration levels. Furthermore, 14 other subjects who were administered one can of the sample for 12 weeks also showed a significant reduction in the levels of serum TC and LDL-C. Thus, daily consumption of this mixed green vegetable and fruit beverage may be useful in lowering serum TC and LDL-C levels in hypercholesterolemic patients.
Oscillations in chemical systems. IV. Limit cycle behavior in a model of a real chemical reaction (1974)

The chemical mechanism of Field, Körös, and Noyes for the oscillatory Belousov reaction has been generalized by a model composed of five steps involving three independent chemical intermediates. The behavior of the resulting differential equations has been examined numerically, and it has been shown that the system traces a stable closed trajectory in three dimensional phase space. The same trajectory is attained from other phase points and even from the point corresponding to steady state solution of the differential equations. The model appears to exhibit limit cycle behavior. By stiffly coupling the concentrations of two of the intermediates, the limit cycle model can be simplified to a system described by two independent variables; this coupled system is amenable to analysis by theoretical techniques already developed for such systems.
Antibacterial Properties of hLf1–11 Peptide onto Titanium Surfaces: A Comparison Study Between Silanization and Surface Initiated Polymerization (2014)

Dental implant failure can be associated with infections that develop into peri-implantitis. In order to reduce biofilm formation, several strategies focusing on the use of antimicrobial peptides (AMPs) have been studied. To covalently immobilize these molecules onto metallic substrates, several techniques have been developed, including silanization and polymer brush prepared by surface-initiated atom transfer radical polymerization (ATRP), with varied peptide binding yield and antibacterial performance. The aim of the present study was to compare the efficiency of these methods to immobilize the lactoferrin-derived hLf1-11 antibacterial peptide onto titanium, and evaluate their antibacterial activity in vitro. Smooth titanium samples were coated with hLf1-11 peptide under three different conditions: silanization with 3-aminopropyltriethoxysilane (APTES), and polymer brush based coatings with two different silanes. Peptide presence was determined by X-ray photoelectron spectroscopy, and the mechanical stability of the coatings was studied under ultrasonication. The LDH assays confirmed that HFFs viability and proliferation were no affected by the treatments. The in vitro antibacterial properties of the modified surfaces were tested with two oral strains (Streptococcus sanguinis and Lactobacillus salivarius) showing an outstanding reduction. A higher decrease in bacterial attachment was noticed when samples were modified by ATRP methods compared to silanization. This effect is likely due to the capacity to immobilize more peptide on the surfaces using polymer brushes and the nonfouling nature of polymer PDMA segment.
Sub-TW laser pulses via post-compression of 9 mJ, 1.2 picosecond laser pulses to 13 fs (Conference Presentation) (2023)

In this work we report experimental compression of 9.4 mJ, 9.4 W, and 1.2 picosecond long pulses down to 7 mJ ,13 fs at 1 kHz in two cascaded stages with gas filled multi-pass cells (MPCs). The output from the first, argon filled MPC is compressed to <50 fs. The output pulses of the subsequent second MPC stage filled with Neon is then compressed to 13 fs using a chirped mirror compressor. The overall transmission, and compression ratio of both stages exceed 74 % and 92 times respectively.
Effect of MMF Harmonics on Single-Phase Induction Motor Performance - A Unified Approach (2007)

Single-phase and two-phase induction machines are widely used in commercial applications due to their low cost and high reliability. The developed methods for the analysis of the single-phase induction motor, i.e. forward-backward field, symmetrical components and cross-field methods, can be adapted for modeling the MMF harmonics effect. This paper presents a unified approach on all these methods that demonstrates the equivalence between models and shows how the equivalent circuit elements can be interchanged from one method to another. Since half-cycle symmetry is a very common condition in the mass produced single-phase induction motors, this paper analyses only the odd MMF harmonic effects. Experimental results for three capacitor-run motors are used to validate all the proposed models.
Feeding and Digestion in Suspension-Feeding Bivalve Molluscs: The Relevance of Physiological Compensations (1988)

SYNOPSIS. Intertidal suspension-feeding bivalves face reductions in the time available for feeding proportional to the duration of aerial exposure. Such individuals do not compensate by increasing their rates of feeding during immersion. Simulations of feeding behaviour, in terms of the energetic balance between the costs and the gains of changes in feeding rate, suggest that variation from the rates characteristic of the sublittoral condition would not enhance net energy gain for intertidal individuals. These findings are consistent with evidence of potential food limitation in the natural sublittoral habitat. Nevertheless, hydrodynamic factors may enhance the supply of food on the shore, so ameliorating the disadvantages of reduced feeding time. In addition, potential physiological compensations for reduced dietary quality include changes in gut residence time, the volume of gut occupied for digestion and (possibly) also in the provision of appropriate digestive enzymes. However, these compensations require days or weeks and are inappropriate on tidal time scales.
The VLF Transmitter, Narrowband Receiver, and Tuner Investigation on the DSX Spacecraft (2023)

Abstract Artificially enhancing the pitch angle diffusion of the relativistic electrons trapped in the radiation belts with transmission of very‐low frequency (VLF) electromagnetic waves is the primary science objective of the wave‐particle interaction experiments (WPIx) on the Demonstration Science Experiments (DSX) spacecraft. The pitch angle diffusion occurs due to the interaction of stimulated whistler‐mode waves with these extremely high energy electrons. The primary payload of the DSX spacecraft is a high‐power VLF transmitter paired with a matched tuner, a two‐channel narrowband receiver, and an 81.6 m tip‐to‐tip carbon fiber longeron dipole antenna, collectively known as Transmitter, Narrowband receiver, and Tuner (TNT) instrument. TNT can execute a wide variety of programmable WPIx experiments and provide supporting in situ and remote plasma characterizations. In its main high‐power mode, the whistler stimulation on selected frequencies between 2.5 and 34 kHz is done by applying a high‐voltage signal, up to nominally 5 kV, at each transmit antenna monopole feed. Maximum power is radiated when the antenna‐plasma circuit reactance is tuned out, leading to resonance conditions at the selected frequency. In the radiation belts, the unknown and varying contributions of the ambient plasma to the total reactance have to be determined automatically and tuned out adaptively, steering the overall VLF circuit within the resonance state as DSX orbits the Earth. Auxiliary to the main WPIx mode, the low‐power relaxation sounding, remote plasma sensing, and listen‐only VLF‐HF emission spectrographic operations are used to probe the surrounding and remote plasma density and the local magnetic field strength.

Oxygen Diffusion and Edema With Modern Scleral Rigid Gas Permeable Contact Lenses (2014)

RmtC introduces G1405 methylation in 16S rRNA and confers high-level aminoglycoside resistance on Gram-positive microorganisms (2010)

Seven plasmid-mediated 16S rRNA methyltransferases (MTases), RmtA, RmtB, RmtC, RmtD, RmtE, ArmA, and NpmA, conferring aminoglycoside resistance have so far been found in Gram-negative pathogenic microorganisms. In the present study, by performing an RNase protection assay, primer extension, and HPLC, we confirmed that RmtC indeed methylates at the N7 position of nucleotide G1405 in 16S rRNA as found in ArmA and RmtB. RmtC has an MTase activity specific for the bacterial 30S ribosomal subunit consisting of 16S rRNA and several ribosomal proteins, but not for the naked 16S rRNA, as seen in ArmA, RmtB, and NpmA. All seven 16S rRNA MTases have been found exclusively in Gram-negative bacilli to date, and no plasmid-mediated 16S rRNA MTase has been reported in Gram-positive pathogenic microorganisms. Thus, we checked whether or not the RmtC could function in Gram-positive bacilli, and found that RmtC could indeed confer high-level resistance to gentamicin and kanamycin in Bacillus subtilis and Staphylococcus aureus. 16S rRNA MTases seemed to be functional to some extent in any bacterial species, regardless of the provenance of the 16S rRNA MTase gene responsible for aminoglycoside resistance.
Preparation and Thermoelectric Properties of Iron Disilicide (2012)

This chapter explores the preparation of a single crystal of ß-FeSi2 by and discusses temperature gradient solution growth techniques and the preparation of bulk polycrystalline ß-FeSi2 by the cold-pressing and sintering method. It describes the thermoelectric properties of the obtained ß-FeSi2 and shows that ß-FeSi2 is a good candidate for many civil applications. Studies on single crystalline ß-FeSi2 significantly extend understanding of the fundamental thermoelectric properties of the material. Thus, an industrial grade of comparatively low-purity starting materials used for thermoelectric purposes is available because the thermoelectric properties are structure insensitive. The effect of the variation of Si composition by Fe-contaminant on thermoelectric properties for sintered compacts FeSi2 should be investigated. The stoichiometric compound iron disilicide (FeSi2) is composed of environment-friendly, nontoxic, and abundantly available elements. ß-FeSi2 is called the “environment-friendly thermoelectric semiconductor” because of its environment-friendly elements, high heat and oxidation resistance, and relatively high thermoelectromotive force.
Alternate stranded triplex formation of chimeric DNA composed of tandem α- and β-anomeric strands (2002)

Refractivity virial coefficients of gaseous CH4, C2H4, C2H6, CO2, SF6, H2, N2, He, and Ar (1991)

Accurate values of the second and third refractivity virial coefficients BR and CR of gaseous CH4, C2H4, C2H6, CO2, SF6, H2, N2, He (only BR is given), and Ar have been measured using the recently improved differential-interferometric technique. This device basically consists of two coupled grating interferometers. During the overflow experiment of the gas one interferometer, with two similar cells in series, measures differentially the higher-order effects of density, and the second interferometer, with two similar cells in parallel, measures at the same time the absolute value of the refractive index. The second interferometer is also used for an accurate control of the decompression during the overflow experiment. It is thus possible to extend the overflow experiments to high values of pressure. The overflow experiments were carried out up to pressures of 35 MPa. The density range extends up to two times the critical density. The third refractivity virial coefficient CR becomes significant for all the gases examined, except for He, when the measurements approach approximately the value 0.3 of the reduced density ρ/ρc. The fourth refractivity virial coefficient DR becomes significant for C2H4, C2H6, and SF6 when ρ/ρc approach approximately the value of one. The agreement between the classically calculated values of BR, based on the dipole induced dipole model, and our experimental BR values is very good for CH4, C2H4, C2H6, SF6, and Ar, but poor for CO2, H2, N2, and He. For He however, the quantum mechanical calculation of BR obtained by including both the long-range and the short-range effects on the polarizability is in remarkably good agreement with our experimental BR value. Accurate values of the first refractivity virial coefficients AR were determined independently by making absolute measurements of the refractive index as a function of pressure.
Bus arrival time prediction model based on APC data (2010)

Bus arrival times are influenced by stochastic variations in number of factors, (e.g., intersection delays, traffic congestion, and weather conditions) resulting in buses to deviate from the predetermined schedule and lengthening of passenger waiting times for buses. Providing passengers with accurate bus arrival times through advanced traveler information systems can help passengers' decision making and reduce average waiting time for buses. In this paper, a set of models, predicting bus arrival times at stops along a route, are developed through mining historical data collected by automated passenger counters (APC). The data applied for developing the models were collected by APC installed on buses operated by the public transit agency in Harbin, a city of northeast region of China. The results obtained are promising, and indicate that the developed models can be used to estimate bus arrival times.
