TL;DR: In this article, the authors investigated a highly renewable Vietnamese power system by jointly optimising the expansion of renewable generation facilities and the transmission grid and showed that in the cost-optimal case, highest amounts of wind capacities are installed in southern Vietnam and solar photovoltaics (PV) in central Vietnam.
Abstract: The Vietnamese Power system is expected to expand considerably in upcoming decades. However, pathways towards higher shares of renewables ought to be investigated. In this work, we investigate a highly renewable Vietnamese power system by jointly optimising the expansion of renewable generation facilities and the transmission grid. We show that in the cost-optimal case, highest amounts of wind capacities are installed in southern Vietnam and solar photovoltaics (PV) in central Vietnam. In addition, we show that transmission has the potential to reduce levelised cost of electricity by approximately 10%.

TL;DR: In this article, the authors studied the dynamical response of the nucleus to an antiproton implanted in its interior, and showed that the compressed state is formed on a rather short time scale of about 4-10 fm/c.
Abstract: On the basis of the kinetic equation with self-consistent relativistic mean fields acting on baryons and antibaryons, we study dynamical response of the nucleus to an antiproton implanted in its interior. By solving numerically the time-dependent Vlasov equation, we show that the compressed state is formed on a rather short time scale of about 4-10 fm/c. This justifies the assumption, that the antiproton annihilation may happen in the compressed nuclear environment. The evolution of the nucleus after antiproton annihilation is described by the same kinetic equation including collision terms. We show, that nucleon kinetic energy spectra and the total invariant mass distributions of produced mesons are quite sensitive observables to the antiproton annihilation in the compressed nucleus.

TL;DR: Bound nuclear systems with two units of strangeness are still poorly known despite their importance for many strong interaction phenomena as discussed by the authors, despite the fact that they represent an unpaired nuclear system.

TL;DR: In this paper, the covariant Hamiltonian principle and the canonical transformation framework are applied to derive a Palatini type gauge theory of gravity, which is generalized by including at the Lagrangian level all possible quadratic curvature invariants.
Abstract: The Covariant Canonical Gauge theory of Gravity is generalized by including at the Lagrangian level all possible quadratic curvature invariants. In this approach, the covariant Hamiltonian principle and the canonical transformation framework are applied to derive a Palatini type gauge theory of gravity. The metric $g_{\mu
u}$, the affine connection $\gamma\indices{^{\lambda}_{\mu
u}}$ and their respective conjugate momenta, $k^{\mu
u\sigma}$ and $q\indices{_{\eta}^{\alpha\xi\beta}}$ tensors, are the independent field components describing the gravity. The metric is the basic dynamical field, and the connection is the gauge field. The torsion-free and metricity-compatible version of the space-time Hamiltonian is built from all possible invariants of the $q\indices{_{\eta}^{\alpha\xi\beta}}$ tensor components up to second order. These correspond in the Lagrangian picture to Riemann tensor invariants of the same order. We show that the quadratic tensor invariant is necessary for constructing the canonical momentum field from the gauge field derivatives, and hence for transforming between Hamiltonian and Lagrangian pictures. Moreover, the theory is extended by dropping metric compatibility and enforcing conformal invariance. This approach could be used for the quantization of the quadratic curvature theories, as for example in the case of conformal gravity.

TL;DR: In this article, the authors used the action integral based on cranking inertia and a potential barrier computed by the macroscopic-microscopic method with a two-center shell model.
Abstract: Superheavy nuclei produced until now are decaying mainly by $\alpha$ emission and spontaneous fission. Calculated $\alpha$ decay half-lives are in agreement with experimental data within one order of magnitude. The discrepancy between theory and experiment can be as high as ten orders of magnitude for spontaneous fission. We analyze a way to improve the accuracy by using the action integral based on cranking inertia and a potential barrier computed by the macroscopic-microscopic method with a two-center shell model. Illustrations are given for $^{282}$Cn which has a measured fission half-life.
