چکیده
It is widely believed that one signal can carry maximum one bit of information, and minimum KTlog2 energy is required to transmit or to erase a bit. Here it is shown four bits of information can be transmitted by one signal in four dimensional space-time. It implies space-time cannot be ignored to determine the minimal energy cost of information

Consider the anisotropic porous medium equation, ut = n ∑ i=1 (um)xixi , where mi > 0, (i = 1, 2, · · · , n) satisfying min 1≤i≤n {mi} ≤ 1, n ∑ i=1 mi > n−2, and max 1≤i≤n {mi} ≤ 1 n (2+ n ∑ i=1 mi). Assuming that the initial data belong only to L(R), we establish the existence and uniqueness of the solution for the Cauchy problem in the space, C([0,∞), L(R))∩C(R× (0,∞)) ∩ L(R × [ε,∞)), where ε...

The Coulomb interaction between the two protons is included in the calculation of three-nucleon hadronic and electromagnetic reactions using screening and renormalization approach. Calculations are done using integral equations in momentum space. The reliability of the method is demonstrated. The Coulomb effect on observables is discussed.

In this paper, we generalise the first Klein-Maskit combination theorem to discrete groups of Möbius transformations in higher dimensions. As a simple application of the main theorem, some examples will be constructed.

We consider a generalized version in continuous time of the parking problem of Knuth. Files arrive following a Poisson point process and are stored on a hardware identified with the real line. We specify the distribution of the space of unoccupied locations at a fixed time and give its asymptotics when the hardware is becoming full.

We develop a new model of a spinning particle in Brans-Dicke space-time using a metric-compatible connection with torsion. The particle's spin vector is shown to be Fermi-parallel (by the Levi-Civita connection) along its worldline (an autoparallel of the metric-compatible connection) when neglecting spin-curvature coupling.
