The six-vertex model, or the square ice model, with domain wall boundary conditions (DWBC) has been introduced and solved for finite N by Korepin and Izergin. The solution is based on the Yang-Baxter equations and it represents the free energy in terms of an N × N Hankel determinant. Paul Zinn-Justin observed that the Izergin-Korepin formula can be(More)
Acoustic metamaterials can be described by effective material properties such as mass density and modulus. We have developed a method to extract these effective properties from reflection and transmission coefficients, which can be measured experimentally. The dependency of effective properties on the positions of the boundaries of the acoustic metamaterial(More)
BACKGROUND The control of sepsis is the primary goal of surgical intervention in patients with infected necrosis. Simple surgical approaches that are easy to reproduce may improve outcomes when specialists in endoscopy are not available. The aim of the present study was to describe the experience with a focused open necrosectomy (FON) in patients with(More)
CONTEXT The surgical treatment of necrotizing pancreatitis includes percutaneous drainage of acute necrotic collections and sequestrectomy in the late phase of the disease. OBJECTIVE The aim of the study was to compare the conventional open necrosectomy (CON) approach with the alternative focused open necrosectomy (FON) approach in patients with infected(More)
This chapter presents a case study, which applies statistical design and analysis to an LC-MS-based -investigation of subjects with coronary artery disease. First, we discuss the principles of statistical -experimental design, and the specification of an Analysis of Variance (ANOVA) model that describes the major sources of variation in the data. Second, we(More)
