The frequency response model of fast and slow twitch muscles at various control strategies (1988)

The frequency response models of the soleus (slow) and m. gastrocnemius (fast) muscles subjected to four types of firing rate and recruitment control strategies applied by electrical stimulation were determined under isometric conditions. Orderly recruitment of motor units was applied concurrently with firing rate increase to elicit 50% and 100% of the initial force to simulate realistic physiological conditions in two of the four strategies. The third strategy recruited motor units according to their size to generate 100% of the force while the firing rate was set constant at its maximum value. The fourth strategy elicited muscle force by increasing the firing rate while all the motor units were constantly active. The method of least squares was used to test for the model with the best fit to the combined response (from 0.4 to 6 Hz) of all preparations of the same muscle. It was concluded that the frequency response model of skeletal muscles could be described by a linear, second-order system with double poles at 1.85 Hz and a pure time delay. The dependence of tendon viscoelastic stiffness on its length is noted as a factor which may modify the contraction velocity of a fast muscle.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">></ETX>
Novel rare-earth-free yellow Ca5Zn3.92In0.08(V0.99Ta0.01O4)6 phosphors for dazzling white light-emitting diodes (2015)

White light-emitting diode (WLED) products currently available on the market are based on the blue LED combined with yellow phosphor approach. However, these WLEDs are still insufficient for general illumination and flat panel display (FPD) applications because of their low color-rendering index (CRI < 75) and high correlated color temperature (CCT = 6000 K). Although near-ultraviolet (UV) LED chips provide more efficient excitation than blue chips, YAG:Ce(3+) phosphors have very weak excitation in the near-UV spectral region. Hence, there is an increasing demand for novel yellow phosphor materials with excitation in the near-UV region. In this work, we report novel self-activated yellow Ca(5)Zn(3.92)In(0.08)(V(0.99)Ta(0.01)O(4))(6) (CZIVT) phosphors that efficiently convert near-UV excitation light into yellow luminescence. The crystal structure and lattice parameters of these CZIVT phosphors are elucidated through Rietveld refinement. Through doping with In(3+) and Ta(5+) ions, the emission intensity is enhanced in the red region, and the Stokes shift is controlled to obtain good color rendition. When a near-UV LED chip is coated with a combination of CZIVT and commercial blue Ba(0.9)Eu(0.1)MgAl(10)O(17) phosphors, a pleasant WLED with a high CRI of 82.51 and a low CCT of 5231 K, which are essential for indoor illumination and FPDs, is achieved.

VICINAL DIBROMO-1-HYDROXYPHOSPHOLANE 1-OXIDES (1981)

Abstract 2,3-Dibromo-1-hydroxyphospholane 1-oxide and 3,4-dibromo-1-hydroxyphospholane 1-oxide were prepared in high yield by bromine addition to 1-hydroxyphosphol-2-ene 1-oxide or 1-hydroxyphosphol-3-ene 1-oxide, respectively. Both compounds were characterized by 1H, 31P and 13C nmr, IR, Laser Raman and mass spectrometry.
Model of the Electronic Structure of Electron-Doped Iron-Based Superconductors: Evidence for Enhanced Spin Fluctuations by Diagonal Electron Hopping (2014)

We present a theoretical understanding of the superconducting phase diagram of the electron-doped iron pnictides. We show that, besides the Fermi surface nesting, a peculiar motion of electrons, where the next nearest neighbor (diagonal) hoppings between iron sites dominate over the nearest neighbor ones, plays an important role in the enhancement of the spin fluctuation and thus superconductivity. In the highest T(c) materials, the crossover between the Fermi surface nesting and this "prioritized diagonal motion" regime occurs smoothly with doping, while in relatively low T(c) materials, the two regimes are separated and therefore results in a double dome T(c) phase diagram.

The "sigmoid septum". Variation in the contour of the left ventricular outt. (1969)

Fifty human hearts were studied for the shape of the left ventricular septum. In certain normal hearts, the base of the ventricular septum may bulge prominently into the outflow tract of the left ventricle. Such hearts have been referred to as having a sigmoid ventricular septum. It was shown that the sigmoid septum of some degree occurred in 24 of 44 apparently normal hearts from adults. The incidence of sigmoid septum increases with age. Classically, hearts with sigmoid septum are not hypertrophied.It is postulated that the condition develops as the result of physiologic decreases in cardiac output which occurs in aging people. This decrease in output leads, in turn, to a shrinking of the left ventricular cavity. The sigmoid septum probably does not result in obstruction to the outflow tract of the left ventricle but, because of its close relationship to the mitral valve, may become obstructive when the mitral valve is replaced by an artificial ball valve.
Sustainable Processes Using Sub- and Super Critical Fluids (2012)

“Process intensification” as a part of necessary sustainable development and “green” revolution uses also high pressure as a processing tool. The main impetus for this is on one way driven by environmental concerns to reduce the usage of conventional solvents and energy. On the other hand high pressure is a tool to design and produce the products with completely new and specified properties. Extraction of substances from plant materials and their “in situ” formulation in products with specific properties is at the moment one of the very promising applications of supercritical fluids. Other advanced processes are polymer processing in/with supercritical fluids, use of sub-and supercritical fluids as sustainable reaction media, etc. The presentation will give also a limited overview of processes and applications of sub-and supercritical fluids as green processing media. For these processes recent advances and trends of developments will be presented. There are several processes using sub- and supercritical fluids which are already developed to the commercial scale, like dry cleaning, high pressure sterilization, jet cutting, thin-film deposition for microelectronics, separations of value-added products from fermentation broths in biotechnology fields and as the solvent in a broad range of synthesis. All of these applications lead to sustainable manufacturing methods that are not only ecologically preferable but also give the products with very special properties. One of the most important advantages of the use of supercritical fluids is selective extraction of components or fractionation of total extracts. This is possible by the use of different gases for isolation/fractionation of components and/or by changing process parameters. Phase equilibria of sunflower and soybean oils in propane and sulphur hexafluoride (SF6) have been investigated. For both systems, the transition of the two-phase system to one-phase system was observed visually at 25°C and 40°C and at different system compositions generally in the range of 0.2–0.7 weight fraction of propane. High-pressure vapor−liquid-phase equilibria (P−T−x−y) for the soybean oil−SF6 and sunflower oil−SF6 systems were investigated at temperatures of (25°C and 40°C) in the pressure range from (1 to 50) MPa. The phase behavior of two vegetable oils in sulfur hexafluoride (SF6) was studied using an isothermal−analytical method in combination with a visual-synthetic method using a variable-volume cell. Moreover, the phase inversions for the vegetable oil−SF6 systems were also recorded at both temperatures under investigation.
Overlapping commutation mode analysis and stable operating regions of a basic series-inverter circuit (1978)

The overlapping commutation mode analysis of a basic series-inverter circuit is analytically explained in relation to the normalized loading parameter λ and normalized control variable μ. The operation of this circuit in overlapping modes is introduced and the circuit stable operating regions are exactly defined, also some interesting characteristics which contradict the traditional analogies are pointed out. For simplifying the calculations the circuit is analysed with a resistive load at the steady state and the mutual coupling between two inductors of this circuit is not considered in this paper.
Comparing the OpenMP, MPI, and Hybrid Programming Paradigm on an SMP Cluster (2003)

Clusters of SMP (Symmetric Multi-Processors) nodes provide support for a wide range of parallel programming paradigms. The shared address space within each node is suitable for OpenMP parallelization. Message passing can be employed within and across the nodes of a cluster. Multiple levels of parallelism can be achieved by combining message passing and OpenMP parallelization. Which programming paradigm is the best will depend on the nature of the given problem, the hardware components of the cluster, the network, and the available software. In this study we compare the performance of different implementations of the same CFD benchmark application, using the same numerical algorithm but employing different programming paradigms. 1.

Monolithic Phononic Crystals with a Surface Acoustic Band Gap from Surface Phonon-Polariton Coupling (2014)

We theoretically and experimentally demonstrate the existence of complete surface acoustic wave band gaps in surface phonon-polariton phononic crystals, in a completely monolithic structure formed from a two-dimensional honeycomb array of hexagonal shape domain-inverted inclusions in single crystal piezoelectric Z-cut lithium niobate. The band gaps appear at a frequency of about twice the Bragg band gap at the center of the Brillouin zone, formed through phonon-polariton coupling. The structure is mechanically, electromagnetically, and topographically homogeneous, without any physical alteration of the surface, offering an ideal platform for many acoustic wave applications for photonics, phononics, and microfluidics.
Status of Pressurized SOFC/Gas Turbine Power System Development at Siemens Westinghouse (2002)

Pressurized solid oxide fuel cell (PSOFC)/micro gas turbine generator (MTG) hybrid power systems have the potential to generate electric power at high efficiency [circa 60% (net AC/LHV)] at multi-hundred kWe and multi-MWe capacities. Thus, good fuel economy and low CO2 emissions are positive system attributes, as are low NOx and SOx emissions due to the propensity of the SOFC for low NOx generation, the need for no firing of the gas turbine combustor during normal hybrid system power operations, and the use of desulfurized fuel. Exhaust temperatures are sufficiently high to enable the recovery of heat for steam/hot-water production, and system energy efficiencies of at least 80% are feasible. Work is ongoing at Siemens Westinghouse on three PSOFC/MTG power systems. Two, with 220 kWe and 300 kWe capacities, are proof-of-concept demonstration units. The 220 kWe PSOFC/MTG power system is in test at the National Fuel Cell Research Center, University of California-Irvine, and the 300 kWe system, which is currently being designed, will be demonstrated in two tests to be performed in Europe. The status of work on the 220 kWe and 300 kWe power systems is reviewed. The third system is to have capacity of at least 500 kWe. This system, which will be demonstrated also, is viewed as a prototype commercial product. The 500 kWe-class PSOFC/MTG concept is described and performance estimates are presented.
Cloud Activation Potentials for Atmospheric α-Pinene and β-Caryophyllene Ozonolysis Products (2017)

The formation of atmospheric cloud droplets due to secondary organic aerosol (SOA) particles is important for quantifying the Earth's radiative balance under future, possibly warmer, climates, yet is only poorly understood. While cloud activation may be parametrized using the surface tension depression that coincides with surfactant partitioning to the gas-droplet interface, the extent to which cloud activation is influenced by both the chemical structure and reactivity of the individual molecules comprising this surfactant pool is largely unknown. We report herein considerable differences in the surface tension depression of aqueous pendant droplets that contain synthetically prepared ozonolysis products derived from α-pinene and β-caryophyllene, the most abundant of the monoterpenes and sesquiterpenes, respectively, that are emitted over the planet's vast forest ecosystems. Oxidation products derived from β-caryophyllene were found to exhibit significantly higher surface activity than those prepared from α-pinene, with the critical supersaturation required for cloud droplet activation reduced by 50% for β-caryophyllene aldehyde at 1 mM. These considerable reductions in the critical supersaturation were found to coincide with free energies of adsorption that exceed ∼25 kJ/mol, or just one hydrogen bond equivalent, depending on the ammonium sulfate and oxidation product concentration in the solution. Additional experiments showed that aldehyde-containing oxidation products exist in equilibrium with hydrated forms in aqueous solution, which may modulate their bulk solubility and surface activity. Equilibration time scales on the order of 10<sup>-5</sup> to 10<sup>-4</sup> s calculated for micrometer-sized aerosol particles indicate instantaneous surface tension depression in the activation processes leading to cloud formation in the atmosphere. Our findings highlight the underlying importance of molecular structure and reactivity when considering cloud condensation activity in the presence of SOA particles.
Regulation of late B cell differentiation by intrinsic IKKα-dependent signals (2007)

NF-kappaB-inducing kinase (NIK)-mediated IKKalpha phosphorylation activates the alternative NF-kappaB pathway, which is characterized by nuclear translocation of p52:RelB heterodimers. This alternative pathway is initiated by a select few receptors, including LT-betaR, BAFF-R, and CD40. Although NIK, IKKalpha, and p52 are all critical regulators of LT-betaR signaling in stromal cells during humoral immune responses, lymphocytes require NIK, but not p52, for optimal Ig production. This disparity suggests that NIK possesses critical cell-type-specific functions that do not depend on NF-kappaB. Here we use mice bearing targeted mutations of the IKKalpha activation loop Ser(176/180) (IKKalpha(AA)) to address the B cell-intrinsic functions of NIK-IKKalpha signaling in vivo. We find that IKKalpha(AA) B cells mount normal primary antibody responses but do not enter germinal centers. This defect likely derives from ineffective early T-B cell collaboration and leads to impaired generation of humoral memory and relatively short-lived, low-affinity antibody production. Our findings contrast with those obtained by using p52(-/-) B cells, which mount normal Ig responses, and alymphoplasia (NIK mutant) B cells, which produce very little primary Ig. Thus, the NIK-IKKalpha-p52 axis is not as linear and exclusive as previous studies suggest, and IKKalpha possesses critical NF-kappaB-independent functions in B cells.

Myostatin Is a Human Placental Product That Regulates Glucose Uptake (2006)

Context: Myostatin is a member of the TGF- superfamily and is primarily known for its ability to inhibit muscle growth. It also has actions on glucose metabolism. We hypothesized that it may act as a paracrine regulator of glucose uptake in the placenta, potentially contributing to fetal and placental growth.
High‐efficiency organic electroluminescent devices using iridium complex emitter and arylamine‐containing polymer buffer layer (2002)

Abstract We have developed efficient organic electroluminescent (EL) devices using a phosphorescent material, tris(2‐phenylpyridine) iridium, Ir(ppy) 3 , as an emitter material and a polymer buffer layer, tetraphenyldiamine‐containing poly(arylene ether sulfone) (PTPDES) doped with tris(4‐bromophenyl) aminium hexachloroantimonate (TBPAH) as an electron acceptor. In this device, a high external quantum efficiency of 21.6% and a luminous efficiency of 82 lm/W (77 cd/A) at 3.0 V were obtained. These high efficiencies can be explained by high quantum efficiency due to phosphorescent Ir(ppy) 3 and high luminous efficiency realized by the use of the polymer buffer layer.

Real-time atomic-resolution imaging of crystal growth process in water by phase modulation atomic force microscopy at one frame per second (2013)

Recent advancement in dynamic-mode atomic force microscopy (AFM) has enabled its operation in liquid with atomic-scale resolution. However, its imaging speed has often been too slow to visualize atomic-scale dynamic processes. Here, we propose a method for making a significant improvement in the operation speed of dynamic-mode AFM. In this method, we use a wideband and low-latency phase detector with an improved algorithm for the signal complexification. We demonstrate atomic-scale imaging of a calcite crystal growth process in water at one frame per second. The significant improvement in the imaging speed should enable various studies on unexplored atomic-scale interfacial processes.
Simple Tuning of the Optoelectronic Properties of Ir<sup>III</sup> and Pt<sup>II</sup> Electrophosphors Based on Linkage Isomer Formation with a Naphthylthiazolyl Moiety (2012)

Abstract By tuning the substitution position of a thiazolyl group on the naphthalene system (α or β site), the distinctive electronic structures associated with these functional ligands have a substantial influence on both the photophysical behavior and electroluminescent (EL) performance of the resulting linkage isomers for two series of Ir III and Pt II phosphorescent emitters. The photoluminescence wavelength can be redshifted by ca. 23 nm for the linkage isomers upon replacing the β‐substituted thiazolyl‐based ligand with its α‐substituted counterpart in the homoleptic series of Ir III phosphors. Furthermore, the bathochromic effect can be as much as ca. 42 nm for the heteroleptic Ir III phosphors and ca. 59 nm for the Pt II compounds. Similarly, metallophosphors that bear β‐substituted ligands exhibit a different EL performance with respect to that of their linkage isomers with α‐substituted ligands. The best EL results associated with the triplet emitters chelated with β‐substituted ligands show a maximum brightness ( L max ) of 22563 cd m –2 , an external quantum efficiency ( η ext ) of 12.88 %, a luminance efficiency ( η L ) of 30.84 cd A –1 , and a power efficiency ( η p ) of 26.17 lm W –1 , whereas the EL performance of their α‐counterparts was characterized by a peak L max of 8653 cd m –2 , η ext of 6.18 %, η L of 8.55 cd A –1 , and η p of 6.54 lm W –1 . Owing to its unique electronic structure, the thiazolyl group is a good alternative to the pyridyl moiety to improve the EL performance of the metallophosphor. We have also demonstrated a simple and useful route to tune the functional properties of cyclometalated triplet emitters for EL applications.
