A new elasto-plastic thin-shell finite element of the absolute nodal coordinate formulation allowing for large deformation and rotation is proposed based on Kirchhoff–Love theory layered plastic model. The von Mises yield criterion plane-stress with linear isotropic hardening adopted in constitutive description material. Owing to constraint, special treatment should be given stress update algor...

The measurement of d coefficients from second-harmonic efficiencies in crystal spheres is studied. KH2PO4 is used as a reference for measurements in spheres and with the Maker-fringes technique. As an example, unknown d coefficients in an orthorhombic mannitol, C6H14O6, in which large coefficients of optical rotation have recently been measured, are determined as d123 = 0.06(2) pm V −1 and comp...

We report a method to determine the four Stokes parameters of each spectral component in a broadband terahertz (THz) pulse by using a continuously rotating analyzer and a standard THz time domain spectroscopy (THz-TDS) instrument. A complete characterization of the polarization state at each frequency is obtained through a single time-domain measurement. Our method requires no specialized THz e...

We suggest that the DNA molecules could form the cholesteric phase owing to an interaction mediated by the network of the hydrogen bonds (H-network) in the solvent. The model admits of the dependence of the optical activity of the solution on the concentration of the PEG, and the change in the sense of the cholesteric twist due to the intercalation by the daunomicyn. Using the experimental data...

INTRODUCTION: During the 2015–2016 academic year, plastic surgery residents accounted for nearly 4.2% of surgical residents and 0.8% of residents overall. While the number of residency programs and allotted residency positions in plastic surgery have been steadily increasing in recent years, little information exists regarding residents who are accepted for plastic surgery residency but never m...

BACKGROUND Plastic surgery is the most competitive specialty in medicine. We sought to identify factors associated with the successful match of generation Y applicants into integrated plastic surgery residency. METHODS We utilized the most recent data from the Charting Outcomes in the Match published by the National Resident Matching Program in 2011. We had data on US senior or independent ap...

BACKGROUND The plastic surgery literature is vast, consisting of a plethora of diverse articles written by a myriad of illustrious authors. Despite this considerable archive of published material, it remains nebulous as to which precise papers have had the greatest impact on our specialty. The aim of this study was to identify the most cited papers in the plastic surgery literature and perform ...

Introduction. "See and treat" one-stop clinics (OSCs) are an advocated NHS initiative to modernise care, reducing cancer treatment waiting times. Little studied in plastic surgery, the existing evidence suggests that though they improve care, they are rarely implemented. We present our experience setting up a plastic surgery OSC for minor skin surgery and survey their use across the UK. Methods...
