We investigate anomaly detection in an unsupervised framework and introduce Long Short Term Memory (LSTM) neural network based algorithms. In particular, given variable length data sequences, we first pass these sequences through our LSTM based structure and obtain fixed length sequences. We then find a decision function for our anomaly detectors based on the One Class Support Vector Machines (...

INTRODUCTION A coronary artery anomaly precludes the use of a trans-annular patch in right ventricular outflow tract (RVOT) reconstruction. Herein we present three patients with coronary artery anomalies who underwent total corrective operations without using a conduit. METHODS Between 2007 and 2010, 84 patients with tetralogy of Fallot (TOF) were operated on. Nine (9.4%) of them had a corona...

The mechanisms of pigeon homing are still not understood, in particular how they determine their position at unfamiliar locations. The "gravity vector" theory holds that pigeons memorize the gravity vector at their home loft and deduct home direction and distance from the angular difference between memorized and actual gravity vector. However, the gravity vector is tilted by different densities...

introduction tekieh lead-zinc ore deposit that is located in the sanandaj-sirjan structural zone has been recognized as one of the most important mineralized regions in malayer-isfahan metallogenic sub-state, south east of arak (momenzadeh and ziseman, 1981). carbonate host units have been developed along (or across) the vishan-tekieh anticline as the main structure extended in nw-se trends (an...

OBJECTIVES The present study evaluates complete supra-annular bioprostheses in patients with an aortic annulus of 18 to 23 mm in diameter. BACKGROUND Aortic valve replacement in patients with small aortic annulus using stented bioprostheses is often associated with unsatisfactory hemodynamic results and high incidence of patient-prosthesis mismatch. METHODS Between February 2000 and January...

We estimated the dip distribution of Oita–Kumamoto Tectonic Line located in central Kyushu, Japan, by using the dip of the maximum eigenvector of the gravity gradient tensor. A series of earthquakes in Kumamoto and Oita beginning on 14 April 2016 occurred along this tectonic line, the largest of which was M = 7.3. Because a gravity gradiometry survey has not been conducted in the study area, we...
