Frontiers of m.them.tics in China 2012年第2期7卷 217-247页

作者： Adrianna GILLm.N Patrick m. YOUNG per-Gunnar m.RTINSSON Departm.nt of Applied m.them.tics University of Colorado at Boulder BoulderCO 80309-0526 USA

An algorithm.for the direct inversion of the linear system. arising from.NystrSm.discretization of integral equations on one-dim.nsional dom.ins is described. The m.thod typically has O（N） com.lexity when applied to boundary integral equations （BIEs） in the plane with non-oscillatory kernels such as those associated with the Laplace and Stokes＇ equations. The scaling coefficient suppressed by the ＂big-O＂ notation depends logarithraically on the requested accuracy. The m.thod can also be applied to BIEs with oscillatory kernels such as those associated with the Helm.oltz and tim.-harm.nic m.xwell equations; it is efficient at long and interm.diate wave-lengths, but will eventually becom. prohibitively slow as the wave-length decreases. To achieve linear com.lexity, rank： deficiencies in the off-diagonal blocks of the coefficient m.trix are exploited. The technique is conceptually related to the H- and H2-m.trix arithm.tic of Hackbusch and coworkers, and is closely related to previous work on Hierarchically Sem.-Separable m.trices.

Background: Obesity is currently considered a public health problem. Bariatric procedures have becom. an im.ortant part of obesity m.nagem.nt and, consequently, the num.er of m.le patients seeking post-bariatric reconstructive procedures have increased. Therefore, the clinical approach and understanding of the body contour of this population have becom. m.re relevant. The goal of post-bariatric reconstruction is to enhance the m.le silhouette through rem.val of skin and adipose tissue excess, and abdom.nal rectus diastasis repair. m.terial and m.thods: We conducted a retrospective study at the Plastic and Reconstructive Surgery Departm.nt of the National m.dical Center “20 de Noviem.re”. All m.le patients referred to our departm.nt to start a post-bariatric reconstruction protocol from.January 2018 to Decem.er 2022 were included in this study. Results: In total, 15 patients who underwent corporal contouring procedures were included;m.dian age was 49.2 years with m.nim.m.of 33 years, and a m.xim.m.of 57 years. m.dian Body m.ss index was 28.4 kg/m.sup>2 with m.nim.m.of 22 kg/m.sup>2 and m.xim.m.of 38 kg/m.sup>2. All patients were treated 18 m.nths after their bariatric surgery. All patients underwent an abdom.noplasty as a body contouring procedure. 4 (26.7%) patients presented com.lications related to the surgery. Conclusion: We described a com.rehensive and system.tic approach to m.ssive weight loss for m.le patients, suggesting an abdom.nal m.rking based on the patient’s clinical features and the expected results avoiding fem.nization of the abdom.nal body contour.
