Objective: To explore the inverted T-shaped flap nursing after breast-conserving surgery combined with reverse double V-shaped mastoconstriction suspension for breast cancer, and summarizes methods experience. Method: 5 patients who underwent and formed incision were selected from same medical group in Department of Breast Cancer Sun Yat-sen University’s Center from February 1, 2019 to Ap...

the paper presents the results of an investigation on the acoustic performance of vertical profile parallel barriers with quadratic residue diffuser tops and faces. a 2d boundary element method (bem) was used to predict the barrier insertion loss. the results of rigid and with absorptive coverage were also calculated for comparisons. using qrd on the top surface and faces of all vertical profil...

U-shaped thin-walled concrete bridge beams usually suffer the combined actions of flexure, shear and torsion, but no research about the behavior of U-shaped thin-walled RC beams under combined actions has been reported in literature. Three large specimens of U-shaped thin-walled RC beams were tested under different torque–bending moment ratios (T–M ratios) of 1:5, 1:1 and 1:0 to investigate the...

| A new method of non-slicing oorplanning is proposed, which is based on the new representation for non-slicing oorplans proposed by [1], called bounded slicing grid(BSG) structure. We developed a new greedy algorithm based on the BSG structure, running in linear time, to select the alternative shape for each soft block so as to minimize the overall area for general oorplan, including non-slici...

A band pass filter with tilted ladder shaped patch and U-shaped geometries is proposed in this paper. Feed are connected at the end of open ended stubs. Presented filter is suitable for the application of wireless application in L-band range. A flat passband response can be achieved when it is employed to implement a bandpass filter. The resonator also exhibits attenuation poles close to the ed...
