In 1967 Winfree proposed a model for coupled oscillators that spontaneously synchronize \cite{winfree2001geometry}. Beyond a critical coupling strength, the oscillators overcome the disordering effect of the dissimilarities in their natural frequencies and spontaneously lock their cycles. Kuramot... |

Multipole moments for static asymptotic flat spacetimes have been first defined by Geroch \cite{GerochI,GerochII}. Later on, Hansen \cite{Hansen} extended this result to the stationary case. Other authors have also interpreted and proposed novel approaches to compute the multipole moments \cit... |

Today we know that galactic globular clusters are old stellar systems and
people are therefore often surprised by the presence of hot stars in these
clusters. As the following paragraphs will show hot stars have been known to
exist in globular clusters for quite some time:

Black-box optimization is the problem of optimizing an objective function $f : \mathcal{X} \mapsto \mathbb{R}$ within the constraints of a given evaluation budget $B$.
In other words, the objective is to obtain a point ${\bf x} \in \mathcal{X}$ with the lowest possible evaluation value $f({\bf x... |

The knowledge of star's ages is important for many areas of modern astrophysics. For example, the studies of the structure and dynamic
of our Galaxy or formation and evolution of planetary systems require precise stellar ages.
There are several technics for age-dating of stars ... |

The Skyrme model is a soliton model for nuclear physics \cite{Sk,book,BR}. The soliton solutions are called Skyrmions, and the conserved integer-valued topological charge of the Skyrmions is interpreted as the baryon number of nuclei. The Skyrme Lagrangian is

The broad and blueshifted \ion{C}{4}$\lambda\lambda 1548,1551$ lines

broad absorption-line quasars (BALQs) reveal the unambiguous signature
of outflows. Therefore, BALQs may be important sources of quasar
feedback in galaxy evolution. In this context, an important pa... |

Atomic nuclei are known to exhibit a wide range of collective excitations~\cite{Boh75}.
Amongst them, giant resonances (GRs) are of particular interest in our understanding of collective motion in nuclei.
Macroscopically, they are associated to high energy modes of small ampl... |

We consider haploid populations with non-overlapping generations. In the absence of epistasis between alleles at a single locus, this analysis could easily be extended to consider diploid populations. We describe here the additive infinite population variants of the model (other variants are descri... |

Recent advances in natural language generation (NLG) have greatly improved the diversity, control, and quality of machine-generated text. However, this increased ability to quickly and efficiently create unique, manipulable, human-like text also presents new challenges for detecting the abuse of... |

The second planet, Venus, is similar to our own planet in terms of mass and size.
In contrast, however, Venus has a massive atmosphere composed mostly of CO$_2$,
and is shrouded by a thick layer of clouds,
which blow around the planet with a period of about four days.
This cloudy atmospher... |

The X-ray nova GS 2023+338 was discovered on 1989 May 22 by the Ginga X-ray satellite ~\citep{1}.
Soon after the object was identified with the variable star V404 Cyg, which had been seen to brighten by seven magnitudes
in the optical in 1938 ~\citep{2,3}. It is now well establi... |

Quantum algorithms are designed to outperform the best classical ones \cite{NC10}. Many nondeterministic NP-hard problems still have only the exhaustive search way to solve them \cite{BBBV96}. The one-way function (oracle) $f(x)$ ($f:\{0,1\}^n\rightarrow \{0,1\}$) can identify t... |

V2051 Ophiuchi was discovered by Sanduleak (1972). It is a dwarf nova,
a compact binary in which mass is fed to a white dwarf (the primary
star) by a Roche lobe filling late-type star (the secondary) via an
accretion disk. V2051 Oph shows recurrent but sparse outbursts in
which the disk expands ... |

Core-collapse supernovae (SNe) are luminous explosions that mark the end of a massive star's life.
These SNe are differentiated from their thermonuclear counterparts (Type Ia SNe) and
are grouped into classes via spectral and photometric analyses \citep[e.g.,][]{1997ARA&A..35..309F}. The majo... |

Arguably, individuals form groups to achieve more ambitious goals than they could achieve alone~\citep{allportInfluenceGroupAssociation1920,caporaelPartsWholesEvolutionary2001}.
