... So it has more time to recognize and interception. And it is regarded as the key phase of missile defense [1]. Lately modeling of micro-motion target and characteristics analysis has brought comprehensive attention. ...

... HALEU is still classified as low-enrichment fuel (as opposed to the highly enriched uranium used to make nuclear bombs), but that distinction is misleading, Lyman says. In June, he and his collaborators -including physicist Richard Garwin, who led the design of the first hydrogen bomb -warned in a Science article that a bomb could be built with a few hundred kilograms of HALEU, with no need for further enrichment 1 . ...

... Kroenig believes these benefits rationalize the United States' robust nuclear force posture that it has maintained for several decades. However, many analysts consider this posture excessive (Fetter et al., 2018) because adversaries would still be incapable of preempting massive retaliation by the United States at lower deployment levels, and dangerous because it increases the chances of triggering a nuclear war-or alternatively, the catastrophic consequences in the event of one-and may have adverse consequences for the proliferation of nuclear weapons and prevention of nuclear terrorism. ...

... Não se pode alegar que o trabalho de Noddack não chegou ao conhecimento dos cientistas interessados. Ao que tudo indica, quase todos os grupos importantes -o de Fermi, na (Hook, 2007;Seaborg, 2007;Alvarez, 1987). Algumas de suas críticas foram endereçadas em trabalhos posteriores de Fermi, como a exclusão do polônio como possível produto daquela reação (Fermi et al., 1934;Amaldi et al., 1935). ...

... rakesh sharma became the first indian astronaut to fly to space with a soviet space module in 1984, marking another high point in science diplomacy. as part of its space diplomacy efforts with friendly countries, the soviet Union originally suggested to india in 1980 that it might launch an indian astronaut to the salyut 7 space station (Braunschvig et al., 2003). the plan was to use space power to extend russia's area of influence. in august 1981, india accepted the offer and collaborative plans were set up. on 3 april 1984, sharma was launched into space alongside two other soviet cosmonauts. ...

... Whereas the condition of mutual vulnerability associated with the possession of nuclear weapons can in theory-by creating a military stalemate-enhance deterrence (Waltz 1990;Jervis 1984),the fear that states might develop strike capabilities that threaten the survivability of others' strategic capabilities-and the concern that an adversary might do so in the future-helps explain why the proliferation of nuclear weapons has continued: as a hedge against technological breakthroughs. This dynamic has been apparent from the Cold War era to the present day (Bracken 1983;Gottfried and Blair 1988). ...

... Satellites of the U.S. Satellite Data System are also in such orbits to facilitate communication with forces in the Arctic. [9] Because the apogee of such orbits is high over the Northern Hemisphere, satellites can be within contact range of ground stations for up to 8 hours of a 12 hour orbital period. Semisynchronous orbits will be used for the new, highly accurate global nav-igation systems of the U.S. such as the Global Positioning System (GPS). ...

... Therefore, Iran's missile and nuclear issue is one of the issues in this document [10] .The traditional concern about Iran's ability to carry nuclear weapons includes a ballistic missile that could reach the United States from Iran. [5] The Joint Comprehensive Plan of Action (JCPOA), failed to address Iran's missile developments and Iran's relations with militant groups. As a result, the UAE, despite its historical differences with Iran, has redoubled its efforts to engage with Iran through health diplomacy during the Covid-19 era. ...
