Objectives: Corticospinal tract (CST) is the most important tract in motor control. However, there was no study about the change of CST location with aging. In this study, using diffusion tensor tractography (DTT), we attempted to investigate the change of CST location at cortex, corona radiata (CR) and posterior limb of internal capsule (IC) level with aging in typically developing children. M...

BACKGROUND AND AIM Individuals with ischemia during cardiac stress-test (cST) have a high risk of developing myocardial infarction (MI), but the pathophysiologic mechanism has never been clarified. It is thought that non flow-limiting coronary plaques (FLP) cause more often MI than FLP, but this is in contradiction with the predictive value of cST. We investigated the correspondence between rev...

We use data on interbank loans and the core equilibrium concept to examine the efficiency of an overnight interbank lending market, and the bargaining power of its participants. In the specific case of Canada’s Large-Value Transfer System, we show that while the market is fairly efficient, systemic inefficiency persists throughout our sample. The level of inefficiency matches distinct phases of...

We prove that every 3-coloring of the edges of the complete graph on n vertices without a rainbow triangle contains a set of order Ω ( n log n ) which uses at most two colors, and this bound is tight up to a constant factor. This verifies a conjecture of Hajnal which is a case of the multicolor generalization of the well-known Erdős-Hajnal conjecture. We further establish a generalization of th...

Background: Carbapenems (CAR), colistin (CST), and tigecycline (TGC) alone or in combination therapy has become the last-resort antibiotics for treating infections caused by multidrug resistant (MDR) bacteria. However, resistance to these reserve antibiotics are increasingly being reported worldwide. Hence, the quest to find other agents that will synergistically restore the efficacy of these a...
