Hyperlipidemia is a major risk factor for erectile dysfunction(ED).Oxidative stress and phenotypic modulation of corpus cavernosum smooth muscle cells(CcSMCs)are the key pathological factors of ED.N-acetylcysteine(NAC)can inhibit oxidative stress;however,whether NAc can alleviate pathological variations in the corpus cavernosum and promote erectile function recovery in hyperlipidemic rats remains unclear.A hyperlipidemia model was established using 27 eight-week-old male Sprague-Dawley(SD)rats fed a high-fat and high-cholesterol diet(hyperlipidemic rats,HR).In addition,9 male SD rats were fed a normal diet to serve as controls(NC).HR rats were divided into three groups:HR,HR+normal saline(NS),and HR+NAC(n=9 for each group;NS or NAc intraperitoneal injections were administered daily for 16 weeks).Subsequently,the lipid profiles,erectile function,oxidative stress,phenotypic modulation markers of ccsMCs,and tissue histology were *** experimental results revealed that erectile function was significantly impaired in the HR and HR+NS groups,but enhanced in the HR+NAC *** lipid levels,over-activated oxidative stress,and multi-organ lesions observed in the HR and HR+NS groups were improved in the HR+NAC ***,the HR group showed significant phenotypic modulation of CCSMCs,which was also inhibited by NAC *** report focuses on the therapeutic effect of NAc in restoring erectile function using a hyperlipidemic rat model by preventing CcSMC phenotypic modulationand attenuating oxidativestress.

Sound insulation measurement of building components combining diffuse acoustic field excitation and near-field acoustic holography reconstruction

引用

Chinese Journal of Acoustics 2024年第2期43卷 248-273页

作者： WANG Hongwei xiong wei WANG Qiaochu ZHANG Guangyao YANG Chenxi School of Architecture South China University of TechnologyGuangzhou 510640 State Key Laboratory of Subtropical Building Science South China University of TechnologyGuangzhou 510640

A method for measuring the airborne sound insulation of building components combining diffuse acoustic field(DAF) excitation and near-field acoustic holography(NAH)radiation intensity reconstruction is proposed. In this method, the DAF is first used to excite the vibration of the component and obtain the incident sound power, then the normal sound intensity distribution with high spatial resolution on the surface of the component is reconstructed from the radiation sound pressure field using the NAH, and finally, according to the sound intensity distribution, the radiated sound power is calculated and the radiation heat areas are located, so as to realize the measurement of sound insulation and sound insulation defects of components. The experimental research in a sound insulation room shows that under the condition that the test distance and sampling interval are both0.04 m, the error of the sound insulation measured by this method compared to the sound pressure method is less than 3.3 d B in the 100–5000 Hz frequency band and less than1.3 d B in the 250–3150 Hz frequency band, and the positioning accuracy of round holes(diameter: 8 mm) and rectangular slots(length: 80 mm, width: 3 mm) is up to the centimeter level. At the same time, the method has strong stability under the influence of certain amount of reverberation and background noise. When reverberation time in the receiving room increases from 1.0 s to 3.4 s(step size: 0.6 s), and the signal-to-noise ratio decreases from 10 d B to 0 d B(step size: 5 d B), the sound volume measurement errors are within 0.8 d B and 0.3 d B, and the defect location errors are within 0.037 m and 0.035 *** proposed method helps to improve the measurement capability of sound insulation characteristics of building components in the laboratory, and it is robust to the receiving room test environment.

Ternary content-addressable memory(TCAM) is an indispensable component of lookup tables in switches or ***, it suffers from expensive and inflexible update operations and cannot fulfill the demand for rule updates in switches enabling software-defined networking(SDN). The main reason is that TCAM stores rules from top to bottom in decreasing order of priority for disambiguation. Updating a TCAM is similar to the insertion sort that takes O(n) time,
