Outcome in Coronary Angioplasty: What Are the Implications for Clinical Practice? To the Editor: The paper by Vakili et al1 seems to have completed the picture; outcome of percutaneous transluminal coronary angioplasty (PTCA) is inversely related to both the operator and institution caseload, not only in the elective setting,2 but also in the emergency primary treatment of acute myocardial infa...

As an aid to understanding the displacement operator definition of squeezed states for arbitrary systems, we investigate the properties of systems where there is a Holstein-Primakoff or Bogoliubov transformation. In these cases the ladder-operator or minimum-uncertainty definitions of squeezed states are equivalent to an extent displacement-operator definition. We exemplify this in a setting wh...

We consider the analysis operator and synthesis dictionary learning problems based on the the `1 regularized sparse representation model. We reveal the internal relations between the `1-based analysis model and synthesis model. We then introduce an approach to learn both analysis operator and synthesis dictionary simultaneously by using a unified framework of bi-level optimization. Our aim is t...

Distribution of distributed generation resources in distribution systems has several advantages, including reducing losses, improving voltage profiles, reducing pollution, and increasing system reliability. However, one of the most important points regarding the placement of these resources in distribution networks is economic issues and the return on investment and the increase in profits from...

Most preferred ordered weighted average (MP-OWA) operator is a new kind of neat (dynamic weight) OWA operator in the aggregation operator families. It considers the preferences of all alternatives across the criteria and provides unique aggregation characteristics in decision making. In this paper, we propose the parametric form of the MP-OWA operator to deal with the uncertainty preference inf...

Background: Heat stress in the steel industry is considered as a serious threat to the health and safety of workers. A wide spectrum of complications and diseases from mild disorders such as burning sensation to fatal conditions such as thermal shock may occur due to uncontrolled thermal stress. In this study, heat stress assessment was performed according to the wet-bulb globe temperature (WBG...

We introduce a new concept of general $G$-$eta$-monotone operator generalizing the general $(H,eta)$-monotone operator cite{arvar2, arvar1}, general $H-$ monotone operator cite{xiahuang} in Banach spaces, and also generalizing $G$-$eta$-monotone operator cite{zhang}, $(A, eta)$-monotone operator cite{verma2}, $A$-monotone operator cite{verma0}, $(H, eta)$-monotone operator cite{fanghuang}...

In this paper, novel stability result for discrete-time infinite horizon optimal control using fuzzy objective functions is presented. For class of control, the goals and constraints introduced in function handle placed on both state vectors. We analyze asymptotic equilibrium law minimum aggregation operator. show that with operator does not guarantee general. This done by deriving an analytica...
