Calcium sensitivity of myosin cross-bridge activation in striated muscles commonly varies during ontogeny and in response to alterations in muscle usage, but the consequences for whole-organism physiology are not well known. Here we show that the relative abundances of alternatively spliced transcripts of the calcium regulatory protein troponin T (TnT) vary widely in flight muscle of Libellula ...

A scintillator-based lost fast-ion probe (LIP) was designed and constructed to measure energetic-ion-losses caused by energetic-ion-drivenMHD instabilities such as Alfvén eigenmodes in the Large Helical Device (LHD). It provides information about the pitch angle and gyroradius of the lost energetic ions simultaneously. It is installed at the outboard side of a horizontally elongated poloidal cr...

in this paper, an energetic coordination compound namely pentamminenitratocobalt(iii) nitrate, [co(nh3)5(no3)](no3)2, was used as a new precursor for the preparation of co3o4 nanoparticles. the results showed that the complex is easily decomposed into the co3o4 nanoparticles at low temperature (200 °c) without employing a surfactant or solvent and any complicated equipment. the product was char...

New imidazole-based energetic molecules (1,4-dinitroimidazole, 2,4-dinitroimidazole, 1-methyl-2,4-dinitroimidazole, and 1-methyl-2,4,5-trinitroimidazole) are studied both experimentally and theoretically. The NO molecule is observed as a main decomposition product from the above nitroimidazole energetic molecules excited at three UV wavelengths (226, 236, and 248 nm). Resolved rotational spectr...

The fully self-consistent simulation of energetic particle turbulence and transport in burning plasmas such as ITER must incorporate three new physics elements: (i) kinetic effects of thermal particles at the thermal ion gyroradius (micro scale), (ii) nonlinear interactions of many meso scale (energetic particle gyroradius) shear Alfvén waves induced by the kinetic effects at the micro scale, a...

Most of the sungrazing comets observed by LASCO at SOHO belong to the Kreutz group of comets and follow trajectories that are tightly clumped in space. Statistical analysis of 9 years of SOHO observations suggests that the true apparition rate of these comets is as high as one every other day. Practically all these comets break up before perihelion passage. Their material is dissociated and ion...

[1] Exospheric atomic hydrogen (H) resonantly scatters solar Lyman‐a (121.567 nm) radiation, observed as the geocorona. Measurements of scattered solar photons allow one to probe time‐varying three‐dimensional distributions of exospheric H atoms. The Two Wide‐angle Imaging Neutral‐atom Spectrometers (TWINS) mission images the magnetosphere in energetic neutral atom (ENA) fluxes and additionally...

[1] The Sub‐keV Atom Reflecting Analyzer instrument on board the lunar orbiter Chandrayaan‐1 provided a large number of measurements of lunar energetic neutral atoms (ENAs). These ENAs were formerly solar wind ions, which were neutralized and backscattered from the lunar surface. The angles under which the ENAs are scattered strongly depend on the solar wind ions’ incidence angle, which corresp...

homologous immunoglobulin-like β-sandwich proteins Running title: Energetic frustrations in β-sandwich proteins Abstract Nonnative residual interactions have attracted increasing attention in recent protein folding researches. Experimental and theoretical investigations had been set out to catch nonnative contacts that might dominate key events in protein folding. However, energetic frustration...

Detonation is an energetic combustion mode augmenting high flow momentum and thermodynamic efficiency, it has been applied in detonation engines, such as pulse engines (PDEs) rotating (RDEs), they have become potential aerospace propulsion equipment. Recently, fluidic jet-in-cross (JICF) demonstrated experimentally numerically that can accelerate the deflagration-to-detonation transition (DDT) ...
