Paper presents a three-level soft switching LLC series resonant dc/dc converter. Zero-voltage (ZVS) is achieved for each main switch without any auxiliary circuit. Voltage stress of half input voltage. Zero-current-switching (ZCS) rectifier diodes. Wide input/output range can be under low frequency because two-stage resonance. Only one magnetic component required in this Efficiency higher high line input, so converter preferable candidate power products with the requirement hold up time. For...
The folding kinetics of a truncated form the N-terminal domain phage lambda repressor [lambda 6-85] has been investigated by using technique dynamic NMR. 6-85 shown previously to fold in purely two-state fashion. This allows determination and unfolding rates from simulation exchange-broadened aromatic resonances Tyr-22. were determined over range 1.35 3.14 M urea. urea dependence both rate constants is exponential, suggesting that rate-determining step invariant at concentrations studied....

Using a data sample with total integrated luminosity of 10.0 pb$^{-1}$ collected at center-of-mass energies 2.6, 3.07 and 3.65 GeV BESII, cross sections for $e^+e^-$ annihilation into hadronic final states ($R$ values) are measured statistical errors that smaller than 1%, systematic about 3.5%. The running strong interaction coupling constants $α_s^{(3)}(s)$ $α_s^{(5)}(M_Z^2)$ determined from the $R$ values.
Recent observations of the light component cosmic-ray spectrum have revealed unexpected features that motivate further and more precise measurements up to highest energies. The Dark Matter Particle Explorer is a satellite-based experiment has been operational since December 2015, continuously collecting data on high-energy cosmic particles with very good statistics, energy resolution, particle identification capabilities. In this work, latest proton+helium in range from 46 GeV 464 TeV are...
We measure the cross section for e+e- -->psi(3770) -->hadrons at Ec.m.=3773 MeV to be (6.38+/-0.08(+0.41)(-0.30) nb using CLEO detector CESR collider. The difference between this and -->DD same energy is found (-0.01+/-0.08(+0.41)(-0.30) nb. With observed total section, we extract Gamma(ee)(psi(3770))=(0.204+/-0.003(+0.041)(-0.027) keV. Uncertainties shown are statistical systematic, respectively.
An enhancement near the mp+MΛ mass threshold is observed in combined pΛ¯ and p¯Λ invariant-mass spectrum from J/ψ→pK−Λ¯+c.c. decays. It can be fit with an S-wave Breit-Wigner resonance a m=2075±12(stat)±5(syst) MeV width of Γ=90±35(stat)±9(syst) MeV; it also P-wave resonance. Evidence for similar ψ′→pK−Λ¯+c.c.

Using 14M $\psi(2S)$ events accumulated by BESII at the BEPC, a Covariant Helicity Amplitude Analysis is performed for $\psi(2S)\to\pi^+\pi^-J/\psi, J/\psi\to \mu^+\mu^-$. The $\pi^+\pi^-$ mass spectrum, distinctly different from phase space, suggests $\sigma$ production in this process. Two theoretical schemes are used global fit to data. results consistent with existence of $\sigma$. pole position determined be $(552^{+84}_{-106})-i(232^{+81}_{-72})$ MeV/$c^2$.
We have studied the inclusive photon spectrum in psi(2S) decays using CLEO III detector. present most precise measurements of electric dipole (E1) transition rates for psi(2S)--> gamma chicJ(1P) (J=0,1,2). also confirm hindered magnetic (M1) transition, psi(2S)-->gamma etac(1S). However, direct M1 etac(2S) observed by Crystal Ball as a narrow peak at energy 91 MeV is not found our data.
