Aim： To establish.an obj.ctive, easy-to-use and compreh.nsive meth.d to analyze corpus cavernosum electromyo- graph.c signals （CC-potentials）. Meth.ds： CC-potentials were recorded during flaccidity in 23 young h.alth. volunteers, with.surface electrodes placed on th. penile sh.ft bilaterally. Based on th. correlation function of Matlab software, an application program for th. analysis of CC-potentials was developed. Individual CC-potentials and th.ir autocorrelation function were evaluated, yielding parameters amplitude （A）, duration （D）, and dominant frequency （DF）. Th. crosscorrelation function of both.longitudinal and bilateral pairs of adj.cent electrodes was calculated to assess th. similar- ity and mutual delay of CC-potentials recorded simultaneously from different parts of th. CC. Th. parameters derived were squared maximum cross-correlation coefficient （Rmax） and delay （τ）. Based on th. absolute value of τ and th. corresponding inter-electrode distance, propagation velocity （PV） was calculated. Results. Th. values of th. parameters were determined automatically. No significant difference related to th. locations of th. electrodes for parameters A, D, and DF was detected. Th. cross-correlation sh.wed th.t both.longitudinal and bilateral CC-potential pairs h.d h.gh.y similar waveforms （th. absolute values of Rmax were 0.80 ± 0.05 and 0.87 ± 0.06, respectively）. PV of longitudinal pairs was estimated as 6.15 ± 3.98 cm/s. Conclusion： Th. application program for correlation analysis of CC-potentials is a compreh.nsive and versatile meth.d to analyze corpus cavernosum electromyograph.c recordings. Its obj.ctiveness makes multi-center application possible.

Convexification of h.brid AC-DC Optimal Power Flow with.Line-Commutated Converters

CSEE j.urnal of Power and Energy Systems 2024年第2期10卷 617-628页

Line-commutated converter (LCC)-based h.gh.voltage DC (h.DC) systems h.ve been integrated with.bulk AC power grids for interregional transmission of renewable power. Th. nonlinear LCC model brings additional nonconvexity to optimal power flow (OPF) of h.brid AC-DC power grids. A convexification meth.d for th. LCC station model could address such.nonconvexity but h.s rarely been discussed. We devise an equivalent reformulation for classical LCC station models th.t facilitates second-order cone convex relaxation for th. OPF of LCC-based AC-DC power grids. We also propose sufficient conditions for exactness of convex relaxation with.its proof. Equivalence of th. proposed LCC station models and properties, exactness, and effectiveness of convex relaxation are verified using four numerical simulations. Simulation results demonstrate a globally optimal solution of th. original OPF can be efficiently obtained from relaxed model.

经尿道前列腺切除术（TURP）中发生的电切综合征是由于过度吸收不含电解质的灌洗液，导致的急性血容量超负荷和低钠血症。椎管内神经阻滞麻醉常被推荐用于TURP，这样可以及时发现神经系统损伤的早期征象。但是对于那些需要全身麻醉的患者则需要有其他持续的无创监测。急性血容量超负荷可以通过血流动力学参数的改变来反映。对主动脉进行经食道多普勒超声成像监测可以测定每搏量和其他与血容量状态相关的血流动力学参数。本文中我们报道第1例在TURP术中通过无创多普勒超声监测血流动力学参数，而发现TURP综合征的情况。

Communications in Th.oretical Ph.sics 2024年第4期76卷 93-112页

We study th. dissociation of ψ(3770), ψ(4040), ψ(4160), and ψ(4415) mesons in collision with.nucleons, wh.ch.takes place in h.gh.energy proton-nucleus collisions. Th. quark interch.nge between a nucleon and a ■ meson leads to th. dissociation of th. ■ meson. We consider th. reactions:■, and■, wh.re R stands for ψ(3770), ψ(4040), ψ(4160), or ψ(4415). A reaction of a neutron and a ■ meson corresponds to a reaction of a proton and th. ■ meson by replacing th. up quark with.th. down quark and vice versa. Transition-amplitude formulas are derived from th. S-matrix *** cross sections are calculated with.th. transition amplitudes for scattering in th. prior form and in th. post form. Th. cross sections relate to nodes in th. radial wave functions of ψ(3770), ψ(4040), ψ(4160), and ψ(4415) mesons.
