This monograph includes five chapters that present recent advancements in physics from authors around the world. Chapter One explores how theories of physics have influenced the international relations discipline and considers what international relations theorists can learn from physics in the future. Chapter Two presents various approaches for determining the electromagnetic field in fixed and steadily rotating charged bodies in the form of a cylinder and a sphere. Chapter Three deals with the synthesis and emission properties of multiple rare earth doped white light-emitting single-phase perovskites. Chapter Four discusses two theoretical methods used to explore the kinetic behaviour of the multi-step process of batch protein crystallisation. Finally, Chapter Five proposes a modified version of the dual copy idea, which states that the two theories of perturbative gluon-gluon and graviton-graviton scattering amplitudes are dual descriptions of the same physics, in which an exact relation between classical, spherically symmetric metrics and gauge field static potentials is established.

Volume 303 begins by examining hyperacute vision experiments based on the eye of a house fly which use solid state electronics to obtain a 10 fold improvement over digital camera technology. This contradicts neuroscience models of hyperacuity based on cortical processing because the house fly does not have a cortex. Following this, the protocol of the seventh dialogue with Uranus inhabitants, including the invitation procedure, is presented and logically analyzed, along with the method for generating gravitational radiation by a neutrino graser. The authors consider the features of the formation of quasi-standing waves in resonators in the presence of factors not previously considered, including: the motion of media filling the resonators, the influence of the magnetization fields on resonators with gyrotropic media and the motion of the boundaries of resonators. Next, a general and pure wave theory of image formation for all types of stellar interferometers, including hypertelescopes, is developed in the frame of Fresnel's paraxial approximations of diffraction. Additionally, the gravitational mass spectroscopy method is used to study the long-range reaction of ovalbumin to the gravitational noise of the Sun and the center of our galaxy. Some aspects of spectrophotometry are discussed, including fast spectrophotometry with a low-resolution imaging spectrograph and the spectral variability of individual stars. Lastly, the authors present the basic elements of Chern-Simon theory and review some recent aspects of developments in Chern-Simon gauge field theory as a topological quantum field theory on a threemanifold.

Horizons in World Physics. Volume 302 considers the explanation of (bio)corrosion and (bio)leaching on the base of changes of electric potentials. (Bio)corrosion and (bio)leaching are terms related to the reaction of dissolution of the metals. While (bio)leaching is desirable, (bio)corrosion is an undesirable phenomenon. Liquid film flows coating a solid surface have received much attention in recent decades due to their vast industrial applications, such as surface protection, lubrication and cooling. The authors suggest several future research directions, including flow control and optimization and machine learning. Additionally, theoretical and experimental studies on the generation of ultra-bright internal second harmonics are presented. A model based on one-dimensional nonlinear Maxwell curl equations without taking into consideration the slowly-varying envelope approximation has been developed. In quantum mechanics and particle physics, Spin is considered as an intrinsic form of the quantum angular momentum of a point particle. As such, the authors aim to demonstrate that in accordance with the creative original idea of Kronig, Uhlenbek and Goudsmit, we can associate Spin with an intrinsic form of two angular momenta of the quantum Spherical Top. The soft physical effects of various forms of shock waves are assessed in the context of molecular ensembles in liquids and polymers for the selective control of the energy state of its individual structural components. In order to describe Hadron dynamics properly, the embedding of 4-dimensional space to 5-dimensional space is tried in lattice simulations, and in the light front holographic quantumchromo dynamics approach in which symmetric light-front dynamics without ghost are embedded in AdS5. This compilation also examines gluons, vector gauge bosons that mediate strong interactions of quarks in quantum chromodynamics. In closing, to solve nonlinear diffusion problems on a sphere, apart from the pole-bordering method, two implicit, balanced and unconditionally stable finite-difference schemes of the second and fourth approximation orders in spatial variables are proposed.

Volume 301 opens with a discussion on how symplectic difference schemes are of great interest because they possess a number of fundamental properties of Hamiltonian differential equations. In particular, they inherit integral invariants such as momentum, angular momentum, and integrals, which are determined by the symplectic structure of the phase space, including the phase-space volume. Following this, the authors describe the dependence of amplified spontaneous emission on the length through the geometrical gain coefficient. In addition, its accuracy in various media with excitation lengths of 200 and 84 cm for N2 and KrF lasers, respectively, is described, and even in small 2-mm-long polymer or few-centimeter-long Ar x-ray lasers. Later, a simple two-dimensional nonstationary problem is formulated for describing the dispersion of a pollutant in a limited area. Its solutions, as well as solutions of an adjoint problem, are used to obtain dual estimates of the pollutant concentration at a point. One study focuses on the dynamics of charged particles subjected to the Lorentz force inside particle accelerators and the correct derivation of their equations of motion and, ultimately, of their trajectories. As we will see, the reason for the increased challenge is the presence of accelerated motion. Many geometrical optics models have been proposed to describe the propagation of paraxial Gaussian beam. However, those paraxial ray-optics models are inapplicable in the paraxial condition. As such, the penultimate chapter introduces a skew line ray-based model to represent the propagation properties of nonparaxial Gaussian beam under the oblate spheroidal coordinates. The free-space evolution of light beam's complex wavefront, including amplitude and phase, is derived via this model.
