Presentation of a new physics theory based on the HM16 model of the ether
Authors: Has Ioan , Miclaus Simona , Has Aurelian 
Published: April 2022

Abstract
In this paper, we present a new physics theory that offers some explanations of physical phenomena in nature, including some that have remained unexplained to date. Our New Physics Theory 2016 (NPT16) is based on a new model of the ether called HM16.
The ether was eliminated from physics in 1905 by Einstein, through his Special Relativity Theory (SRT), based on experiments carried out in 1881/87 by Michelson (ME81/87). We reintroduce the ether to physics as a result of two errors that we have discovered in Michelson’s analysis of his experiments ME81/87. We initially proposed the development of NTP16 in 2016, and we now present an actualised, up-to-date form of NPT16. NPT is the result of taking into account the special properties of ETH ether, which in the HM16 model is characterized by its composition, as a deformable elastic body, without friction, so without energy consumption/loss. ETH consists of compact ether cells EC, which transmit the fundamental vibrations FVs of ECs, created by microparticles MPs, constituted as energy concentrations in their own vortices/oscillations, energy that creates even the mass m of MP. Longitudinal and transverse FVs vibrations, are transmitted between MPs and between ECs, by mechanical percussion pi, specific to the current positive or negative electric charge of an MP. And gravity is the result of the interaction forces FDC between the dipoles, so-called electric, but created by a Coulomb type force FCC, between two MPs completed with a term in lnr. And at astronomical distances, there is a ratio R = FDC/FN ≈ 1.60, which indicates the presence of an increase in the real mass of the stars, of about +60%, compared to the mass considered by gravitational Newton force FN, a result that can explain/replace the current fictitious dark matter. The NPT also gives a physical explanation of the phenomenon of increasing the mass of a material body MB, as its speed V increases. This speed V, leads to an accumulation of energy around MPs, stored in the ECs vortices of ETH around MP, created even by the V-speed motion of the MP. And the energy accumulated around the MP is added to the MP’s own energy, which is even the mass of the MP thus increased.
4G model of final unification – A brief report
Authors: Seshavatharam U V S , Lakshminarayana S 
Published: April 2022

Abstract
To understand the mystery of final unification, in our earlier publications, we proposed that, 1) There exist three atomic gravitational constants associated with electroweak, strong and electromagnetic interactions; 2) There exists a strong interaction elementary charge in such a way that, its squared ratio with normal elementary charge is close to reciprocal of the strong coupling constant; and 3) Considering a fermion-boson mass ratio of 2.27, quarks can be split into quark fermions and quark bosons. Further, we noticed that, electroweak field seems to be operated by a primordial massive fermion of rest energy 584.725 GeV and hadron masses seem to be generated by a new hadronic fermion of rest energy 103.4 GeV. In this context, starting from lepton rest masses to stellar masses, we have developed many interesting and workable relations. With further study, a workable model of final unification can be developed.
Logical and historical review on theoretical physics
Authors: Kanda A , Prunescu M , Wong R , Apostoli P 
Published: April 2022

Abstract
Since it started about three centuries ago, theoretical physics went through a huge advancement and, particularly in the last century, the development was material. Its application to engineering brought a massive revolution in the way we humanity live now. Its interpretation opened up astoundingly deep understanding of our universe. One important research activity for the future is to further develop our theories and to further deepen our understanding of the universe. However, as Tomonaga said, when we are in a phase of looking for new paradigm, it is important to understand how our current theory was developed. The purpose of this paper is to present a logical and historic study of the conceptual development of theoretical physics. As the field of theoretical physics is so vast, we cannot cover all theories we have now. We will focus on the most fundamental theories of physics. As this field of physics is as deep and intricate as pure mathematics, if not more, it will be helpful to compare our challenge with that pure mathematicians are facing in the field of the foundations of mathematics. Such common ground will inevitably lead us to deeper philosophical issues. After all what we call physics started with Newton who developed both calculus and dynamics. He called it not physics but natural philosophy. So, it is naturally expected that philosophy, mathematics and theoretical physics develop hand in hand. It has been about a century since these fields started to develop separately and it is about time to restart the original interaction between these three intrinsic intellectual activities. Certainly this will help our timely search for a new paradigm. We must move forward.

Authors: Lin Haibo , Wang Jinbao 
Published: March 2022

Abstract
The Airy beam shows its peculiar property of self-healing which attracts lots of attentions to do the researches about the higher dimensional nondiffraction beams which can apply to lots of aspects to doing researches. We demonstrate the self-healing property of Airy beam which displays similar profiles both in weak and strong turbulence in atmosphere. Highly similarity has been shown when the propagation distance is not very long. The self-healing exhibits its own profile in strong turbulence and stability in weak turbulence respectively with the longer propagation distance. However, the variation of exponential truncation factors and the transverse scales would not change the conclusion that the self-healing property would vanish at the same propagation distance both in weak and strong turbulence. It means that they would reach zero intensity plane with the same self-healing critical distance zs
and would not entirely disappear until reach the same disappearance critical distance zd
. This study provide a method to enhance the self-healing property of Airy beams.

Abstract
The integration of III/V materials into silicon-based microelectronics has been the momentum in the development progress of silicon photonics in the past few decades. In this paper, the growth of InAs/GaAs quantum dots with the high density of 6.5 × 1010/cm2 on silicon substrate is demonstrated. The influence of different deposition amount of indium on the density of quantum dots under the same arsenic flux pressure is discussed in detail, from 2.21 monolayer, 2.38 monolayer to 2.55 monolayer. Atomic force microscopy measurement and photoluminescence test are conducted to characterize the materials growth. The InAs/GaAs quantum dots exhibit the best dot density and size uniformity as well as the strongest intensity of photoluminescence at the deposition amount of 2.38 monolayer. This result provides stable foundation for the realization of III/V quantum dot materials as the photonic components into silicon-based lasers.

Authors: Yang Huagen , Feng Kan , Li Rong , Yan Jing 
Published: March 2022

Abstract
Based on the Generalized Snell’s Law (GSL), combined with the elastic wave propagation theory in the thin plate and beam structure, a new type of elastic wave metasurface is constructed. The metasurface structure realizes the design of equal gradient of transmitted wave phase according to the difference of the length of different helical curved beams. Through this structure, the transmission wavefront of the Lamb wave in the thin plate is controlled, and acoustic phenomena such as negative refraction and asymmetric transmission are realized, which proves the accuracy of the GSL theory and the feasibility of the structure. And on this basis, the use of the design of symmetrical attachment to the metasurface solves the problem of destroying the plate structure in the traditional elastic wave metasurface, and provides an effective new idea for the elastic wave metasurface.

Abstract
Abstract.The fatigue bending life of wire rope is an important parameter of its service performance. In this study, three kinds of 6X19W+FC wire ropes with different diameters were selected, and each wire rope was equipped with pulleys of different diameters. The fatigue bending lives of the three wire ropes under different axial tensile loads were tested. On this basis, based on Feyrer’s bending fatigue estimation theory of steel wire rope, a binary quadratic regression function for predicting steel wire rope bending fatigue life is obtained by using multiple linear regression method, and the validity of the prediction equation is verified by comparing the theoretical predicted value with the experimental results.

Published: March 2022

Abstract
Upward ( phase i ) pipe jacking project of hangzhou water intake is near existing bridge foundation and operating tunnel. In order to investigate the influence of pipe jacking construction process on existing structures, Plaxis 2D finite element software was used to simulate the horizontal and vertical displacement of existing structures caused by pipe jacking construction. The calculation results show that: The horizontal displacement of bridge pile foundation is nonlinear distribution. There is a bending point in the pile foundation. The maximum and minimum horizontal displacement are 0.71 mm and-0.84 mm, respectively. The maximum vertical settlement is only 0.29 mm. The horizontal displacement of the sidewall of the tunnel structure is nonlinear distributed, and the displacement near the pipe jacking is relatively large, but the maximum displacement is only 0.13 mm. The vertical deformation of tunnel structure is mainly uplift deformation, and the uplift near the pipe jacking is obvious, but the extreme value of uplift is only 0.09 mm. Thus, the impact of pipe jacking construction on bridges and tunnels is very limited. The research results are of great significance to the safety evaluation of pipe jacking engineering near construction.
Research on Dynamics Behaviors of Two Coaxial Circular Cylindrical Thin Shells Constructed with Functionally Graded Materials
Authors: Cao Jianhua 
Published: March 2022

Abstract
The paper reports the dynamic characteristics of two coaxial circular cylindrical thin shells (CCTSs) containing internal or annular flowing fluid in which one shell is constructed with functionally graded materials (FGMs). A new set of shell equations are firstly used to analyse the vibration of fluid-conveying thin shells. Two cases, i.e. inner shell or outer shell is constructed with FGMs, are calculated by adopting the Galerkin’s method. The results show that as the volume fraction index increases, the natural frequencies don’t always decrease which depend on the positions of FGM shell and flowing fluid of two coaxial CCTSs. The paper indicates that the effects of FGM shell cannot be neglected for the design of FGM shells conveying fluid.

Published: March 2022

Abstract
In view of the influence of high temperature formation fluid during the staged stimulation of ultra-deep oil and gas wells, the change of wellbore temperature field may cause casing rupture and compression. Based on the law of momentum conservation and energy conservation, an iterative calculation model of deep annulus pressure is established to study the variation law of confined annulus between packers. According to casing wear shape, the calculation model of residual strength and safety evaluation are established. The casing annulus pressure of L-3 well is predicted by casing annulus pressure prediction model, and the sensitivity analysis is carried out. The results show that the errors between the measured and predicted values of casing annulus are within the allowable range and the model accuracy is high. The effects of annulus liquid and tubing coefficients on annulus pressure are studied, and the effect of wear depth on casing safety factor is studied. In this paper, the effects of annulus pressure and casing wear on wellbore integrity in ultra-deep wells are considered comprehensively, and a method for production casing safety evaluation is developed.

Published: March 2022

Abstract
Recently, thermal metamaterials which can control heat flux at will have attracted many researchers and they can be used in many thermal application scenarios such as thermal concentration and thermal cloak. In this paper, this dynamic thermal metadevice with a vertical rotation coupling component can achieve the target of switchable thermal effect based on effective medium theory and scattering cancellation method. Firstly, this metadvice can adjust the effective thermal conductivities in the region with two novel vertical rotation rings by tuning the rotational velocity. Additionally, an almost undistorted and nonspinning thermal field in the central region can be obtained via this novel design. Furthermore, compared with the previous work, this metadevice can implement the continuous modulation of the effective thermal conductivity at will by adopting a vertical rotation scheme, realizing various thermal functionalities such as thermal concentration and thermal cloak. Then, we demonstrate the switchable effect of this dynamic thermal metadevice in simulations. Meanwhile, the variations of temperature along the measured horizonal line are also shown in simulations. In contrast to previous approaches, this dynamic thermal metadevice may provide more dynamic thermal manipulation inspirations for designing novel multifunctional thermal metadevices.

Condensation heat transfer deterioration on superhydrophobic surface with dense nanostructures
Authors: Kan Tongli , Xu Jinliang , Xie Jian 
Published: March 2022

Abstract
Superhydrophobic surface with dense nanostructures was fabricated on copper substrate by template-assisted electrochemical deposition. During deposition process, bubbles generated and stayed at some regions to prevent the fabrication of nanostructure, yielding heterogeneous surface. To prepare homogeneous surface, the electrolyte composition and plating voltage are optimized. Repeated experiments of condensation heat transfer on superhydrophobic surface were performed. The heat transfer performance is deteriorated during experiments. Compared with hydrophilic and smooth surface, heat transfer coefficient on fresh superhydrophobic surface was improved by 154.3%, maximally. However, the heat transfer coefficient of superhydrophobic surface after repeated tests behaves only maximum 67.2% improvement. To explore the mechanism of heat transfer deterioration, SEM images and EDS elemental analysis were used. There is no obvious change of nanostructure after repeated experiments. However, the polymer attached on nanostructure to provide hydrophobicity is destroyed. This paper warns that the robustness of both nanostructure and polymer need to be considered to fabricate superhydrophobic surface with excellent condensation heat transfer performance.
