Li–O2 batteries have attracted much attention due to its ultra-high theoretical energy density;
however, an overpotential of large charging/discharging limits its development. Herein, we …

epidemiological importance, given the substantial increase in its prevalence; at present, …

Despite the importance of early diagnosis and intervention, the diagnosis of autism spectrum
disorders (ASDs) remains delayed as it is mostly based on clinical symptoms and abnormal …

Comets must form a major part of the interstellar medium. The solar system provides a flux
of comets into the interstellar space and there is no reason to suspect that many other stars …

We investigate whether it is possible that viable microbes could have been transported to
the Earth from planets in extra-solar systems by means of natural vehicles such as ejecta …

Assuming the Jovian planets experienced smooth orbital migrations, Malhotra successfully
explained some important features of the Kuiper Belt by the mechanism of resonance capture…

It is generally assumed that the Solar System is surrounded by a swarm of comets, the so-called
Oort Cloud, which contains approximately 10 11 members. The observed comets …

The inner two planets around 55 Cancri were found to be trapped in a 3 : 1 mean motion
resonance (MMR). In this paper, we study the dynamics of this extrasolar planetary system. Our …

Triplets of galaxies offer a good opportunity to measure the amount of dark matter in systems
of galaxies. We use the extensive data set on triplets by Karachentsev et al.[Isv. Spec. …
