Topological phases in electronic structures contain a new type of topology, called fragile, which can arise, for example, when an elementary band representation (atomic limit band) splits Garcinia Cambogia into a particular set of bands.For the first time, we obtain a complete classification of the fragile topological phases, which can be diagnosed

Sometimes, we consider some certain criterions of the superiority in the jurisprudence that discord apparently with human and moral principles.In this paper, firstly, we reconnoiter these criterions, then, because of uncertainty about existence of such sentences in sharia, toner we investigate the measure of their stability by study juridical and r

Using a cross-sectional survey concussion knowledge was evaluated among forty university-level athletes (n = 20, rugby union players; n = 20, Gaelic football players) and eight experienced team coaches (n = 2, rugby union; n = 2, Gaelic football; n = 1, soccer; n = 1, hockey; n = 1, netball; n = 1, basketball).Levels of knowledge of concussion were

The optical-phased array (OPA) has gained special interest in recent years as a high-speed and compact imaging device.While large-scale OPAs have been demonstrated in single-pixel imaging, the complexity of the driver circuit is becoming a crucial problem as the number of phase shifters increases.Here, we investigate the phase shift requirement of

Problem.The main trends in the car gasification are considered.It is shown that after the global automakers lost the interest in the creation and production of gas engines, the development of gas systems continues in the secondary market.A noticeable decrease in the valve train durability due to the valve recession was noted, which can make the Foo
