The rise of sea level will enhance erosion of cliffs that will be in the reach of storm waves in the distant future. We analyse the possible consequences of erosion-driven collapse of the cliff of Cap Canaille, located approximately 20 km from Marseille, France. A resulting fall of large amount of rocks (several millions m3) into the sea (or a subaerial landslide of an equal volume) may generate a local tsunami that will endanger the adjacent seaside resort Cassis. The propagation of waves, created by this hypothetic event, is simulated using the fully non-linear Boussinesq wave model FUNWAVE. The maximum elevation in Cassis may reach 3.6 m and it only weakly depends on the particular scenario of the collapse. The largest source of danger is the short arrival time (3–3.5 min) of the first wave that is also the highest one. This requires implementation of nontraditional means for building resilience of the local coastal community with respect to such events.

Предложена модель первичного вакуума, состоящего из частиц с планковскими масштабами длины, времени жизни и массы, которые названы эфиронами. Квантовое гравитационное поле отождествляется с возбужденным состоянием эфиронного бозе-конденсата. Гравитон определяется как квазичастица волнового поля свободных эфиронов. В рамках квантово-полевого подхода дано объяснение формулы закона всемирного тяготения. ...

This study proposes to minimize Rényi and Tsallis entropies for finding the optimal number of topics T in topic modeling (TM). A promising tool to obtain knowledge about large text collections, TM is a method whose properties are underresearched; in particular, parameter optimization in such models has been hindered by the use of monotonous quality ...

In the framework of circular restricted three-body problem the libration point orbits form the families of periodic and quasi-periodic solutions. In the paper, the mapping of initial conditions is utilized to describe and study the structure and properties of these families. A new numerical method for orbit generation, which is applicable both for the periodic ...

The method of reduction of linear electric equivalent schemes is considered in this article. This method uses the property of the scheme which consists of subschemes with minimum connections. The macromodeling method is suggested to use for each subscheme. The macromodeling method allows excluding unimportant inner variables so the common count of equations will be ...

In this article, we show numerically the strong finite-size effects in exponential random graphs. Particularly, for the two-star model above the critical value of the chemical potential for triplets a ground state is a star-like graph with the finite set of hubs at network density p<0.5p<0.5 or as the single cluster at p>0.5p>0.5. We find that there exists ...

In the usual everyday life, it is well known that the inverted pendulum is unstable and is ready to fall to “all four sides,” to the left and to the right, forward and backward. The theoretical studies and the lunar experience of moon robots and astronauts also confirms this property. The question arises: Is this ...

Уравнение Шрёдингера играет важную роль в квантовой механике, ядерной и волновой физике, в нанотехнологиях и др. Часто его приходится решать в неограниченных областях. Для этой цели разработано немало подходов, использующих приближенные прозрачные граничные условия (ПГУ) на искусственных границах. К числу лучших из них относятся дискретные ПГУ, для которых отражения от искусственных границ полностью отсутствуют, вычисления ...

A new approach is proposed to solve the quantum evolution problem for a system with an arbitrary number of coupled optical parametric processes. Our method is based on the canonical transformations which define the evolution of the system in the Heisenberg picture. This theory overcomes the difficulties arising in the Wei–Norman method. The application of ...

We consider an initial-boundary value problem for a generalized 2D time-dependent Schrödinger equation on a semi-infinite strip. For the Crank-Nicolson finite-difference scheme with approximate or discrete transparent boundary conditions (TBCs), the Strang-type splitting with respect to the potential is applied. For the resulting method, the uniform in time L2-stability is proved. Due to the ...

We construct asymptotic solutions of the Navier–Stokes equations. Such solutions describe periodic systems of localized vortices and are related to topological invariants of divergence-free vector fields on two-dimensional cylinders or tori and to the Fomenko invariants of Liouville foliations.

To solve it, any order finite element in space and the Crank-Nicolson in time method with the discrete transpa\-rent boundary conditions (TBCs) has recently been constructed. Now we engage the global Richardson extrapolation in time to derive the high order ...
