A detailed description of the baryon direct Urca processes A: n → p + e + ν_e, B: Λ→ p + e + ν_e and C: Ξ^-→Λ + e + ν_e related to the neutron star cooling is given in the relativistic mean field approximation. The contributions of the reactions B and C on the neutrino luminosity are calculated by means of the relativistic expressions of the neutrino energy losses. Our results show that the total neutrino luminosities of the reactions A, B and C within the mass range(1.603–2.067) M_⊙((1.515–1.840) M_⊙ for TM1 model) for GM1 model are larger than the corresponding values for neutron star without hyperons. Furthermore, although the neutrino emissivity of the reaction A is suppressed with the appearance of the proton ~1S_0 superfluid, the contribution of the reactions B and C can still quicken a massive neutron star cooling. In particular, the reaction C in PSR J1614-2230 and J0348+0432 is not suppressed by the proton ~1S_0 superfluid due to the higher threshold density of the reaction C, which will further speed up the two pulsars cooling.

Dissipative Kerr solitons(DKS) have long been suffering from poor power conversion efficiency when driven by continuous-wave lasers. By deriving the critical coupling condition of a multimode nonlinear optics system in a generalized theoretical framework,two efficiency limitations of the conventional pump method of DKS are revealed: the effective coupling rate is too small and is also power-dependent. A general approach is provided to resolve this challenge by introducing two types of nonlinear couplers to couple the soliton cavity and CW input through nonlinear processes. The collective coupler opens multiple coupling channels and the self-adaptive coupler builds a power-independent effective external coupling rate to the DKS for approaching the generalized critical coupling condition, which promises near-unity power conversion efficiencies. For instance, a conversion efficiency exceeding 90% is predicted for aluminum nitride microrings with a nonlinear coupler utilizing second-harmonic generation. The mechanism applies to various nonlinear processes, including Raman and Brillouin scattering, and thus paves the way for micro-solitons toward practical applications.

Aim: Extensive neurophysiological investigations were carried out in 100 healthy subjects and 84 patients with penileerectile dysfunction. Methods: Following examinations were performed, spinal and scalp somatosensory evoked poten-tials (SEPs) to stimulation of the dorsal nerve of penis, motor evoked potentials (MEPs) from bulbocavernosus (BC) inresponse to scalp and spinal root stimulation, and measurement of sacral reflex latency (SRL) from anal sphincter (AS).Results: In the healthy subjects, the mean sensory total conduction time (sensory TCT), as measured at the peak of thescalp P1 (P40) wave was 39.73 ms. The mean sensory central conduction time (sensory CCT = spinal-to-scalp conductiontime) was 28.98 ms. The mean peripheral conduction time (PCP) was 9.40 ins. Transcranial brain stimulation was per-formed by using a magnetic stimulator during voluntary contraction of the examined muscle. Spinal root stimulation wasperformed at rest. Motor total conduction time (motor TCT) to BC muscles was 20.48 ms. Motor central conductiontime (motor CCT) to sacral cord segments controlling BC muscles was 14.42 ms at rest. The mean SRL was 35.13 ***: Combined or isolated abnormalities of SEPs, MEPs, and SRL were found in patients with erectile dysfunc-tion. (Asian J Androl 1999 Sep; 1 : 145 - 150)
