In the 15 years since Froome achieved the generally accepted value for the velocity of light as 299 792.5 km/s with an accuracy of about ±1 10-6, work has continued in many laboratories to improve this accuracy and to refine the value accepted for c. A summary is given of the major ...
Innate behaviors meet multiple needs adaptively and in a serial order, suggesting the existence of a hitherto elusive brain dynamics that brings together representations of upcoming behaviors during their selection. Here we show that during behavioral tr
In accordance with this reference architecture, it can be considered as a data warehouse system, which in addition to the core data warehouse features two other important components: The data staging area [54, 55] represents the core of the ETL process, which is responsible for ingesting new d...
In days of high-speed train research and 3 , scientists were once faced with a noise problem. The trains pushed air through tunnels at 4 speeds. So, when a train came out of a tunnel, it could be very, very 5 . However, kingfisher birds hardly make a sound when they get into ...
This study is the first part of a larger investigation into the fire behaviour of green façades. In this study, the currently known international rese
Typhoon disasters undergo a complex evolutionary process influenced by temporal changes, and investigating this process constitutes the central focus of geographical research. As a key node within the typhoon disaster process, the state serves as the fou

For this reason, a variety of fuels can be used (Figure 1). Each solid oxide fuel cell consists of three main parts: cathode, electrolyte, and anode. In this type of battery, fuel (usually hydrogen) is introduced to the anode and oxidant (oxygen in the air) to the cathode. When ...
The oceans are responsible for making conditions on Earth suitable for us to live on it. Our rainwater, drinking water, weather systems, and climate are all ultimately provided and kept in balance by the oceans. We rely on them as a major source of the food we eat, and they produce the...
In the last decades, metasurfaces have attracted much attention because of their extraordinary light-scattering properties. However, their inherently static geometry is an obstacle to many applications where dynamic tunability in their optical behaviour is required. Currently, there is a quest to enable...
