The connection joint of prestressed concrete pipe piles is a typical steel–concrete structure, and its bending strength has evolved into critical factor affecting the safety supporting structures in underground engineering. Based on full-scale tests five specimens large-diameter reinforced (PRC) joints, as well corresponding finite element numerical simulation, bearing deformation characteristi...

This paper presents a didactic mathematical method to evaluate the self-inductance of a nonmagnetic core single-layer cylindrical and helicoidal coil presenting voids between turns. This type of calculation, using Biot–Savart Law, is not usually presented in the traditional electromagnetic text books, but constitutes an excellent tool to show to the students how to apply the very important Biot...

Expanding upon an observation of Hou [Math. Comp., submitted], exact desingularizations are presented of the Euler equations in two and three dimensions for which the singularity within the Biot-Savart integrand is reduced by one order. The reformulated equations are then solved numerically using either the point vortex method or the vortex blob method. The increased smoothness of the Biot-Sava...

PURPOSE We studied the association between admission white blood cell (WBC) count and short term outcome in patients with acute cerebral infarction. METHODS 2808 patients with acute cerebral infarction were included in the study. WBC count and other variables were collected within the first 24 hours of admission. Clinical outcomes (death or dependency) were evaluated by neurologists during ho...

The paper starts with a summary of the way the new theories of international trade have incorporated the role of multinational companies (MNCs) in the location of production. The main, specific assumptions used to incorporate MNCs’ activities relate to joint inputs at the company’s level combined with assumptions regarding costs at the plant level and spatial transaction costs. It is claimed th...

Erratum After the publication of this work [1] it was noticed that the citation lists on figures 3 and 4 were incorrect. The original version of this article was corrected. The citation list on figure 3 was put as: [9, 10, 13, 16, 17, 25–27, 29–35, 38, 39, 42, 43, 53, 54, 57, 59, 62–65, 67, 85, 87–90, 92, 93, 95–97] It should have been: [85, 59, 91, 89, 29, 87, 25, 87, 26, 90, 92, 93, 54, 16, 8...

AIMS We decided to determine the long-term survival of patients after alcohol septal ablation (ASA) for hypertrophic obstructive cardiomyopathy (HOCM) and compare this with the general population. METHODS AND RESULTS A total of 178 highly symptomatic, consecutive patients (58 ± 12 years, 53% women) were treated by ASA between April 1998 and April 2013 and followed-up for 4.8 years (IQR 2.1-7....
