Th.s is a Unified Field description based on th. h.lograph.c Time Dilation Cosmology, TDC, model, wh.ch.is an eternal continuum evolving forward in th. forward direction of time, at th. speed of ligh., c, at an invariant 1 s/s rate of time. Th.s is th. Fundamental Direction of Evolution, FDE. Th.re is also an evolution down time dilation gradients, th. Gravitational Direction of Evolution, GDE. Th.se evolutions are gravity, wh.ch.is th. evolutionary force in time. Gravitational velocities are compensation for th. difference in th. rate of time, dRt, in a dilation field, and th. dRtis equal to th. compensatory velocity’s percentage of c, and is a measure of th. force in time inducing th. velocity. In applied force induced velocities, th. dRt is a measure of th. resistance in time to th. induced velocity, wh.ch.migh. be called “anti-gravity” or “negative gravity”. Th. two effects keep th. continuum uniformly evolving forward at c. It is demonstrated th.t gravity is already a part of th. electromagnetic field equations in way of th. dRt element contained in th. TDC velocity formula. Einstein’s energy formula is defined as a velocity formula and a modified version is used for ch.rged elementary particle solutions. A time dilation-based derivation of th. Lorentz force ties gravity directly to th. electromagnetic field proving th. unified field of gravity and th. EMF. It is noted h.w we could possibly create gravity drives. Th.s is followed by a discussion of black h.les, proving supermassive objects, like massive black h.le singularities, are impossible, and th.t black h.les are massless Magnetosph.ric Eternally Collapsing Objects (MECOs) th.t are vortices in spacetime. .

Journal of Modern Ph.sics 2024年第4期15卷 448-461页

作者： Joseph.h. (Cass) Forrington Managing Editor Journal of Cosmology California USA

Th.s paper is a furth.r elaboration of th. auth.r’s Time Dilation Cosmology (TDC) h.lograph.c model th.t ties gravitation and celestial mech.nics and kinematics directly to time dilation, resolving all th. major conundrums in astroph.sics, and ties astroph.sics directly to quantum ph.sics. It begins with.a brief summary of th. TDC model and contains th. new derivation for th. time dilation version of th. formula for summing relativistic velocities, Einstein’s gravitational constant and th. time dilation versions for th. Lorentz factor and th. Euclidean norm of th. 3d velocity vector, th. two of wh.ch.can th.n be used in th. Four-velocity formula. It is demonstrated h.w orbital curvature is manifested as th. resultant of two time dilation-manifested velocities. It also explains wh. an interferometer cannot distinguish.free fall from zero gravity and furth.r elaborates on th. auth.r’s previous explanations of h.w spiral galaxies are formed, and contains math.matical proof th.t Black h.les are actually Magnetosph.ric Eternally Collapsing Objects (MECOs) th.t are massless spacetime vortices.

We study th. distribution of quasars on th. celestial sph.re according to ground-based SDSS and space-based WISE and Gaia observations. All distributions as a function of galactic latitude, b, exh.bit a decrease in quasar frequency well outside th. dust in and near th. galactic plane. We prove th.t th. observed decrease in quasar frequency at h.gh.galactic latitudes is not accompanied by reddening, meaning th.t it can not be caused by dust. Th. scattering of ligh. by th. circumgalactic gas is negligible because th. Th.mson scattering cross section is very small. We conclude th. observed scattering of ligh. must be caused by dark matter in th. galactic h.lo. We determine th. mass and ch.rge of dark matter particles. If th. dark matter particle is a fermion its mass, mDMand ch.rge eDM=δe, wh.re e is th. elementary ch.rge are: mDM=3.2×10−2eV and δ=3.856×10−5. If h.wever th. dark matter particle is spinless th.n: mDM=0.511eV and δ=2.132×10−4. Th.se values for th. ch.rge of a dark matter particle are orders of magnitude h.gh.r th.n th. upper limit of th. neutrino ch.rge according to laboratory experiments. Consequently, dark matter particles are not ch.rged neutrinos. Since dark matter particles are ch.rged, th.y must emit and absorb electromagnetic radiation. h.wever, PDM~δ2, or: PDM~1.487×10−9Pe, wh.re Peis th. power output of a single electron.

Delamination is a prevalent type of damage in composite laminate structures. Its accumulation degrades structural performance and th.eatens th. safety and integrity of aircraft. Th.s study presents a meth.d for th. quantitative identification of delamination identification in composite materials, leveraging distributed optical fiber sensors and a model updating approach. Initially, a numerical analysis is performed to establish.a parameterized finite element model of th. composite plate. Th.n, th.s model subsequently generates a database of strain responses corresponding to damage of varying sizes and locations. Th. radial basis function neural network surrogate model is th.n constructed based on th. numerical simulation results and strain responses captured from th. distributed fiber optic sensors. Finally, a multi-island genetic algorith. is employed for global optimization to identify th. size and location of th. damage. Th. efficacy of th. proposed meth.d is validated th.ough.numerical examples and experiment studies, examining th. correlations between damage location, damage size, and strain responses. Th. findings confirm th.t th. model updating tech.ique, in conjunction with.distributed fiber optic sensors, can precisely identify delamination in composite structures. © 2024 Th. Auth.rs.

Background: Understanding h.w to improve mental h.alth.literacy is conducive to maintaining and promoting individuals’ mental h.alth.and well-being. h.wever, to date, interventions for mental h.alth.literacy primarily depend on traditional education and contact interventions, wh.ch.h.ve limitations with.regard to pertinence and individualization. Artificial intelligence (AI) and big data tech.ology h.ve influenced mental h.alth.services to be more intellectual and digital, and th.y also provide greater tech.ical convenience for individualized interventions for promoting mental h.alth.literacy. h.wever, th.re is relatively little research.on th. effectiveness of individualized online intervention for mental h.alth.literacy in th. literature. Th.s study aims to fill th.s void. To verify wh.th.r individualized online intervention can improve th. level of mental h.alth.literacy. Meth.ds: We conducted a pretest–post-test control experiment. Th. participants were recruited from a large community located in central Ch.na. A total of 152 participants completed th. research. We use mixed linear model estimation and paired t-tests to analyze th. data. Results: Individualized online intervention can effectively improve th. mental h.alth.literacy level of participants. Specifically, we found th.t compared with.th. control group, th. mental h.alth.literacy in th. experimental group was significantly improved after receiving individualized online intervention. Likewise, th. mental h.alth.literacy of th. control group h.s also improved after receiving individualized online intervention. In addition, we compared th. mental h.alth.literacy level of th. experimental group at Time 3 to th.se at Time 2 and found th.t th. mental h.alth.literacy level at Time 3 h.d not decreased one month.later. Th.s sh.ws th.t individualized online intervention was not only momentarily effective, but also h.d long-term efficacy. Conclusion: Th.s study illustrates th.t th. individualized online intervent

Soil salinization is a globally prevalent abiotic environmental stress. Th. imbalance of ions caused by h.gh.concentrations of sodium ch.oride results in a 40% reduction in soybean yield. Soybean, as an important crop for soil quality improvement, necessitates th. identification of salt-tolerant varieties and germplasms to effectively utilize and enh.nce saline-alkali land. In th.s study, we assessed th. salt tolerance of 435 soybean varieties and germplasms during th. seedling stage. Among th.m, Qih.ang34, You2104, h.ngzh.dou, Pamanh.idou, and Osage exh.bited grade 1 salt tolerance rates surpassing oth.r tested materials. Furth.rmore, h.ngzh.dou and Qih.ang34 demonstrated h.gh.r salt tolerance during germination and emergence stages based on th.ir elevated rates of emergence, salt tolerance index, ch.oroph.ll content, and sh.ot fresh.weigh.s. Overall findings provide valuable resources for molecular breeding efforts aimed at developing salt-tolerant soybean varieties suitable for cultivation in saline-alkali soils. © 2024 th.
