Yttrium oxide (Y2O3) and ytterbium (Yb)-doped Y2O3 particles were synthesized via the sol-gel method from the aqueous solution of their nitrate salts. The synthesized powders were then deposited on Corning glass substrates ...

Halloysite is a natural clay mineral that belongs to the kaolin group. Its chemical formula is Al2(OH)4Si2O5.nH2O. When n is equal to 2, it is hydrated, and when n is equal to 0, the halloysite is dehydrated. Generally, ...

In this study, the active controlled single degree of freedom (SDOF) structures with 0.5, 1.0 and 2.0 s period are investigated under various pulse-type ground motions (1.5, 2.0, and 2.5 s) to optimally tune the parameters ...

Semih Emre Çekin Influence of German Monetary Policymaking on the ECB: Obstacle or Opportunity? “I certainly would not say that we are ‘just’ one of 17 central banks. We are the largest and most important central bank in ...

Sentiment analysis is a process of computationally detecting and classifying opinions written in a piece of writer’s text. It determines the writer’s impression as achromatic or negative or positive. Sentiment analysis ...

Kepler observations revealed that hundreds of stars with near-solar fundamental parameters and rotation periods have much stronger and more regular brightness variations than the Sun. Here we identify one possible reason ...

We present an update of our previous work, necessitated by availability of a significantly improved dataset. The work is a model-independent analysis of the cosmological supernova (type Ia) data, where function families ...

Scholars have long recognized the existence of myriad widespread deep disagreements on values, justice, morality, and ethics. In order to come to terms with such deep disagreements, resistant to rational solution, this ...

Metallic materials including stainless steel, cobalt-chromium alloys, titanium and its alloys, and nickel-titanium (NiTi) shape memory alloys have been used in biomedical applications since the 1940s due to their favorable ...

Successful short-term implementation of nickel-titanium (NiTi) alloys as implants has been a motivation for the development of long-term applications. However, rendering these as safe implant materials is challenging. The ...
