    Opis:
    A new mechanics of physical objects with negative mass is proposed. Their properties are explained by the positive inertia of any body with a mass of any sign. Accordingly, the principle of equivalence of inert and gravitational masses has been adjusted. Particles of negative mass repel each other from bodies with a positive mass and attract each other, forming huge islands of negative matter. Such particles are called negaons. The energy and temperature of the negaons are negative.

    Opis:
    In this paper, a new Multi-Layer Perceptron Neural Network (MLP NN) classifier is proposed for classifying sonar targets and non-targets from the acoustic backscattered signals. Besides the capabilities of MLP NNs, it uses Back Propagation (BP) and Gradient Descent (GD) for training; therefore, MLP NNs face with not only impertinent classification accuracy but also getting stuck in local minima as well as lowconvergence speed. To lift defections, this study uses Adaptive Best Mass Gravitational Search Algorithm (ABGSA) to train MLP NN. This algorithm develops marginal disadvantage of the GSA using the bestcollected masses within iterations and expediting exploitation phase. To test the proposed classifier, this algorithm along with the GSA, GD, GA, PSO and compound method (PSOGSA) via three datasets in various dimensions will be assessed. Assessed metrics include convergence speed, fail probability in local minimum and classification accuracy. Finally, as a practical application assumed network classifies sonar dataset. This dataset consists of the backscattered echoes from six different objects: four targets and two non-targets. Results indicate that the new classifier proposes better output in terms of aforementioned criteria than whole proposed benchmarks.

    Opis:
    The gravitational force between the mass of an average mammalian cell and the earth is in the order of a picoNewton. When applied across the plasma membrane the energy is within the domain of 10-20 J that is associated with the distance between forces of ions that are correlated with the membrane potential. Solutions for velocity and acceleration are congruent with known properties of the ion channel and cell membrane. The differences in gravitational forces between lunar perigee and apogee are within the 10-20 J range when applied across distances that constitute neuronal processes. Calculations of the ratio of gravitational force to a specific range of intensities of rotating experimental magnetic fields produce equivalent electric dipole moments (A∙m) that are within the same order of magnitude as that measured for single post-synaptic potentials. These values match the energies associated with pressures within the cell volume according to Borowski’s gravitational theory. The solutions may explain a robust behavioral effect reported over 40 years ago that indicated a powerful interaction between forces associated with lunar distances at the birth of rats exposed prenatally to rotating magnetic fields. Although the energies may be small the contributions from subtle changes in gravitational forces are within the operative range for those that influence cell function.
