摘要： Both mass and charge are needed to create a rotating Black Hole as has been investigated in great mathematical detail by the Reissner-Nordstrom metric and the Kerr-Newman metric. It is their application to astronomical phenomena that they have stated difficulty with because astronomical objects have no net electric charge and that is what we are exploring. While the energy in the gravitational field of the mass of a Neutron Star alone cannot create a stationary Black Hole, together with the energy in the strong magnetic field created by a rotating Neutron Star a rotating Black Hole is formed. Black Holes are the portal to the next higher spatial dimension.

摘要： BACKGROUND Endometriosis affects approximately 10%of reproductive-age women,however,endometriosis associated malignant transformation is rare and is often report as a rare case.CASE SUMMARY Herein,we report of a 49-year-old female patient who suffered from severe left lower abdominal pain and imaging examination revealed an irregular mass in the left iliac fossa.Histopathological examination revealed main undifferentiated adenocarcinoma with a few typical endometrial epithelial and stromal tissues in the adjacent area.Combined with the immunohistochemical staining and the negative intra-or postoperative results from exploratory laparotomy,gastroscopy,enteroscopy and positron emission tomography,the tumor was considered to be derived from endometriosis.The patient underwent hysterectomy,bilateral salpingectomy,bilateral ovariectomy,and multipoint biopsy of the pelvic peritoneum.Subsequent radiotherapy and chemotherapy were performed.The patient recovered well post-operation and there was no evidence of recurrence after 10 mo of follow-up via computed tomography and magnetic resonance imaging.CONCLUSION This case highlights a rare presentation of mass-like extragonadal endometriosis associated malignant transformation in the pelvis.Endometriosis associated malignant transformation is rare and difficult to diagnose in clinical settings,with diagnoses depending on pathological results and the exclusion of metastasis from other organs.Fortunately,patients are often diagnosed at younger ages,as well as at early stages;thus they generally have relatively favorable prognoses.

摘要： Fundamental period is an important parameter in seismic design and performance assessment of buildings.Hence,comprehensive and detailed investigations of effectiveness as well as affectability of this parameter can result in the design of high-performing earthquake-resistant structures.On this basis,this research intends to evaluate the effects of variations of mass and stiffness on the fundamental periods of two three-and nine-story structures representing low-and high-rise buildings,respectively.To this end,a MATLAB code was developed and validated to determine the fundamental periods of structures with various mass and stiffness characteristics.Numerous case studies were performed to investigate the effects of mass and stiffness variations along the stories of the considered structural models.The objective of this research endeavor is to provide a better understanding of affectability of fundamental period under different design considerations.

摘要： In the course of a research study on Lorentz transformations and the theory of relativity, the fundamentals of the relativistic concepts of space and time, the relations of those concepts to Lorentz transformations, and equivalence of mass and energy were studied. Many important references on the said subjects were reviewed. This paper draws attention to some critical questions that have risen in the course of that research study on the concepts of expansion of time and unbounded increase of a particle’s mass with velocity.

摘要： In this paper, I show that the Special Relativistic effect of mass increase that occurs within objects when they move at high speed can be explained using Classical Physics principles. In my analysis, the wave nature of condensed matter and energy/mass equivalence are taken into consideration. The wave nature of particles is modelled as the particle structure comprising three-dimensional standing waves. When this is done, the difference in the energy sum of the component waves that comprise a particle moving at a high speed, when compared to those of a stationary particle, completely accounts for the mass increase. Furthermore, the additional momentum of the wave components in the direction of motion (the Longitudinal direction) is the cause of the inertia, or effective mass, of the object being greater than that in the Transverse direction (orthogonal to the direction of motion).

摘要： 1 This paper considers Lagrangian finite elements for structural dynamics constructed with cubic displacement shape functions.The method of templates is used to investigate the construction of accurate mass-stiffness pairs.This method introduces free parameters that can be adjusted to customize elements according to accuracy and rank-sufficiency criteria.One-and two-dimensional Lagrangian cubic elements with only translational degrees of freedom(DOF)carry two additional nodes on each side,herein called side nodes or SN.Although usually placed at the third-points,the SN location may be adjusted within geometric limits.The adjustment effect is studied in detail using symbolic computations for a bar element.The best SN location is taken to be that producing accurate approximation to the lowest natural frequencies of the continuum model.Optimality is investigated through Fourier analysis of the propagation of plane waves over a regular infinite lattice of bar elements.Focus is placed on the acoustic branch of the frequency-vs.-wavenumber dispersion diagram.It is found that dispersion results using the fully integrated consistent mass matrix(CMM)are independent of the SN location whereas its lowfrequency accuracy order is O(κ8),whereκis the dimensionless wave number.For the diagonally lumped mass matrix(DLMM)constructed through the HRZ scheme,two optimal SN locations are identified,both away from third-points and of accuracy order O(κ8).That with the smallest error coefficient corresponds to the Lobatto 4-point integration rule.A special linear combination of CMM and DLMM with nodes at the Lobatto points yields an accuracy of O(κ10)without any increase in the computational effort over CMM.The effect of reduced integration(RI)on both mass and stiffness matrices is also studied.It is shown that singular mass matrices can be constructed with 2-and 3-point RI rules that display the same optimal accuracy of the exactly integrated case,at the cost of introducing spurious modes.The optimal SN location in two-dimensional,bicubic,isoparametric plane stress quadrilateral elements is briefly investigated by numerical experiments.The frequency accuracy of flexural modes is found to be fairly insensitive to that position,whereas for bar-like modes it agrees with the one-dimensional results.

摘要： Background:COVID-19 is an acute infection of the respiratory tract that emerged in late 2019.Currently identified methods for identifying the severe acute respiratory syndrome coronavirus 2 virus include methods that detect the presence of the virus itself,such as reverse transcription PCR and isothermal amplification methods,and those that detect antibodies produced in response to the infection.Reverse transcription PCR and quantitative PCR are highly sensitive but have a narrow time window of sensitivity.Methods:We investigated a new method to detect the occurrence of severe acute respiratory syndrome coronavirus 2 by analyzing the early rise in leukocyte levels which has a characteristic set of ratios of leukocyte types which identify the viral pathogen and distinguish it from a number of others.We used the Albert Einstein Hospital,São Paulo data set and the Athena AI System to validate this method.Results:The sensitivity of the test is up to 98.67%prediction of positives from full blood count results.Conclusion:We have discovered an early test for SARS-CoV-2 which can be performed using a black-boxed AI to give high sensitivity prediction of COVID-19 infection.
