BACKGROUND Surgical site infections (SSIs) increase morbidity and mortality rates and generate additional cost for the healthcare system. Pre-operative blood transfusion and the subcutaneous fat thickness (SFT) have been described as risk factors for SSI in other surgical areas. The purpose of this study was to assess the impact of pre-operative blood transfusion and the SFT on the occurrence o...

Solitary fibrous tumor (SFT) is a mesenchymal neoplasm of fibrous origin. The 2013 WHO classification of soft tissue tumors defines malignant forms as hypercellular, mitotically active (>4 mitosis/10 high-power fields), with cytological atypia, tumor necrosis, and/or infiltrative margins. With an IRB-approved protocol, we investigated patient records and clinicopathologic data from our Sarcoma ...

Bandpass filters (BPFs) are very important to extract target signals and eliminate noise from the received signals. A BPF of which frequency characteristics is a sum Gaussian functions called mixture (GMBPF). In this research, we propose implement GMBPF approximately by several components sliding Fourier transform (SFT) or attenuated SFT (ASFT). Because component SFT/ASFT can be realized using ...

We give a simple proof that the Neumann coefficients of surface states in Witten’s SFT satisfy the Hirota equations for dispersionless KP hierarchy. In a similar way we show that the Neumann coefficients for the three string vertex in the same theory obey the Hirota equations of the dispersionless Toda Lattice hierarchy. We conjecture that the full (dispersive) Toda Lattice hierachy and, even m...

Let R be a pseudo-valuation domain with associated valuation domain V and I a nonzero proper ideal of R. Let R̂ (resp., V̂ ) be the I-adic (resp., IV -adic) completion of R (resp., V ). We show that R̂ is a pseudo-valuation domain (which may be a field); and that if I 6= I2, then V̂ is the associated valuation domain of R̂. Let R be an SFT globalized pseudo-valuation domain with associated Prüfer do...

The effects of surface roughness as induced by marine fouling on the hydrodynamic forces a submerged floating tunnel (SFT) are experimentally and numerically investigated in detail at Reynolds numbers Re = 8.125 × 103–5.25 104. A sensitivity analysis to different parameters including height, skewness, coverage ratio, spatial arrangement is performed. In addition, an optimized parametric cross-s...

Fat-forming solitary fibrous tumor (SFT), previously known as lipomatous hemangiopericytoma, was described as an uncommon variant of extrapleural SFT in the 2013 World Health Organization (WHO) classification of soft tissue tumors. 1 Fat-forming SFT is an uncommon, slow-growing neoplasm and is characterized by the typical histologic features of SFT with a mature adipocytic component. The fat-fo...
