We calculate fine-structure corrections to the spectrum of $\frac{\ensuremath{\psi}}{J}$ particles in charmonium model, assuming that linear potential which confines quarks is due an effective vector exchange. also electromagnetic decay rates between various low-lying $s$ and $p$ states.
Background One of the most important challenges in study aging is to discover compounds with longevity-promoting activities and unravel their underlying mechanisms. Royal jelly (RJ) has been reported possess diverse beneficial properties. Furthermore, protease-treated RJ (pRJ) additional pharmacological activities. Exactly how pRJ exert these effects which components are responsible for largely unknown. The evolutionarily conserved mechanisms that control longevity have indicated. purpose...
The H-dibaryon resonance was sought by a ΛΛ invariant mass spectrum that obtained the C12 (K−,K+ΛΛX) reactions. We observed bump near threshold, as reported previous experiment (KEK E224), with better statistics. Data were compared results of cascade model calculation including final state interactions consistent newly measured binding energy ΛΛ6He. No significant enhancements above levels predictions observed. resulting upper limit for production cross section H range between and ΞN...
The international Muon Ionization Cooling Experiment (MICE), which is under construction at the Rutherford Appleton Laboratory (RAL), will demonstrate principle of ionization cooling as a technique for reduction phase-space volume occupied by muon beam. channels are required Neutrino Factory and Collider. MICE evaluate in detail performance single lattice cell Feasibility Study 2 channel. Beam has been constructed ISIS synchrotron RAL, Step I, it characterized using beam-instrumentation...
A new muon beamline, science innovative channel (MuSIC), was set up at the Research Centre for Nuclear Physics (RCNP), Osaka University, in Osaka, Japan, using 392 MeV proton beam impinging on a target. The production of an intense relies efficient capture pions, which subsequently decay to muons, novel superconducting solenoid magnet system. After pion-capture first $36^\circ$ curved transport line commissioned and flux measured. In order detect target either copper or magnesium placed stop...
The amino acid sequence of chicken liver xanthine dehydrogenase (EC 1.1.1.204) was determined by cDNA cloning and partial sequencing the purified enzyme. enzyme consisted 1358 acids with calculated molecular mass 149,633 Da. In order to compare structure rat enzymes, limited proteolysis performed dehydrogenase. When digested subtilisin, it not converted from NAD-dependent type O2-dependent oxidase type, in contrast mammalian However, cleaved mainly into three fragments a manner similar that...
A facility that can deliver beams of electron and muon neutrinos from the decay a stored beam has potential to unambiguously resolve issue evidence for light sterile arises in short-baseline neutrino oscillation experiments estimates effective number flavors fits cosmological data.

Ordinary muon capture (OMC) on enriched $^{100}\mathrm{Mo}$ isotopes was studied for the first time to investigate neutrino nuclear responses neutrinoless double-$\ensuremath{\beta}$ decays and supernova interactions. Muon proceeds mainly as $^{100}\mathrm{Mo}(\ensuremath{\mu},xn)^{100\ensuremath{-}x}\mathrm{Nb}$ with $x$ being number of neutrons emitted from negative capture. The Nb isotope mass distribution obtained by measuring delayed $\ensuremath{\gamma}$ rays radioactive...
A knob bow fibula (Bügelknopffibel) of the Leutkirch type, which typologically belongs to second half 4th and early 5th century CE, was excavated in 2018 Roman city Augusta Raurica, present-day Kaiseraugst (AG, Switzerland). This analyzed for first time its elemental composition by using non-destructive technique Muon Induced X-ray Emission (MIXE) continuous muon beam facility at Paul Scherrer Institute (PSI). In present work, detection limit is 0.4 wt% with ∼ 1.5 hours measurement time. The...
A powder-like 0.09 mm/sup 2/ 2.45 GHz RF identification chip for wireless recognition applications is described. This fabricated in a 0.18 /spl mu/m CMOS process, and its thickness 60 mu/m. two-surface connection technique adopted to facilitate antenna attachment. The distance between the reader 300 mm power of mW.
Electron- or X-ray-induced characteristic X-ray analysis has been widely used to determine chemical compositions of materials in vast research fields. In recent years, X-rays from muonic atoms, which a muon is captured, attracted attention because both beam and muon-induced have high transmission abilities. Here we report the first non-destructive elemental carbonaceous chondrite using one world-leading intense direct current source (MuSIC; MUon Science Innovative Channel). We successfully...
