This thesis studies the effect of unstable leaders in Paxos protocol. Paxos algorithm is one of the most popular solutions for distributed consensus, and is often used for building replicated state machines. Safety is guaranteed by Paxos algorithm regardless of various machine and communication failures. However, the liveness is compromised when multiple Paxos leaders exist at the same time. Al...

Background Patients with unstable angina despite intensive medical therapy, ie, refractory angina, are at high risk for developing thrombotic complications: myocardial infarction or coronary occlusion during percutaneous transluminal coronary angioplasty (PTCA). Chimeric 7E3 (c7E3) Fab is an antibody fragment that blocks the platelet glycoprotein (GP) Ib/IIIa receptor and potently inhibits plat...

We prove a consistency results saying, that for a simple (first order) theory, it is easier to have a universal model in some cardinalities, than for the theory of linear order. We define additional properties of first order theories, the n-strong order property (SOPn in short). The main result is that a first order theory with the 4-strong order property behaves like linear orders concerning e...

This paper studies long-run inflation targets and stability in an imperfect information environment. When central banks set an inflation target that is not fully communicated, agents draw inferences about inflation from recent data and remain alert to structural change in their econometric model by forming expectations from a forecasting model that is estimated via discounted least squares. Inf...

It is widely perceived that unstable angina is a critical phase of coronary heart disease. The risk of acute myocardial infarction or death in these patients is high: up to 5% during hospitalization, 20% within 30 days, and 25% in 6 months. Medical and invasive treatment options for these patients have been rather discouraging, with two reasons responsible for this unsatisfactory state: first, ...

The air-injection as an active flow stabilizing techniques, were numerically examined in current work, during the aerodynamic behavior and the characteristics of an axial compressor. At first, in design condition the characteristic curve was numerically captured for a specified test compressor. The computed results showed good agreements with those obtained from the experiments, to validate the...

Proprioception is essential for joint function and through which individual can detect body parts movement in space. Aim of present study is to investigate effect of balance training on unstable platform with tilting, translation and combined motion on knee joint position sense in active young males. 39 healthy active male divided in to three training and control (n=9) groups. Training on unsta...
