A simple phenomenological model is developed, which indicates the existence of.a direct link between the concept of.rest mass of.a particle and magnetodynamic energies associated to the f.rmation of.the particle. The model is based upon the principles of.quantization and conservation of.f.ux, well known f.r their application in superconductivity. The charge of.particles is considered as f.rming vortices of.superconducting currents, which we postulate are created by electromagnetic f.uctuations f.om vacuum (or related processes). A new quantization rule gathers the size, the magnetic moment, and the rest mass of.the particle and associates these quantities to the integer number of.f.ux quanta that should be stored in the vortices corresponding to each particle. The model is applied to the electron, the muon, the proton, and the neutron. Quantitative consistency with available experimental data f.r these subatomic particles is obtained.

The present paper is based upon the f.ct that if.an object is part of.a highly stable oscillating system, it is possible to obtain an extremely precise measure f.r its mass in terms of.the energy trapped in the system, rather than through a ratio between f.rce and acceleration, provided such trapped energy can be properly measured. The subject is timely since there is great interest in Metrology on the establishment of.a new electronic standard f.r the kilogram. Our contribution to such ef.ort includes both the proposal of.an alternative def.nition f.r mass, as well as the description of.a realistic experimental system in which this new def.nition might actually be applied. The setup consists of.an oscillating type-II superconducting loop subjected to the gravity and magnetic f.elds. The system is shown to be able to reach a dynamic equilibrium by trapping energy up to the point it levitates against the surrounding magnetic and gravitational f.elds, behaving as an extremely high-Q spring-load system. The proposed energy-mass equation applied to the electromechanical oscillating system eventually produces a new experimental relation between mass and the Planck constant.

Artif.cial Intelligence (AI) is transf.rming organizational dynamics, and revolutionizing corporate leadership practices. This research paper delves into the question of.how AI inf.uences corporate leadership, examining both its advantages and disadvantages. Positive impacts of.AI are evident in communication, f.edback systems, tracking mechanisms, and decision-making processes within organizations. AI-powered communication tools, as exemplif.ed by Slack, f.cilitate seamless collaboration, transcending geographical barriers. f.edback systems, like Adobe’s Perf.rmance Management System, employ AI algorithms to provide personalized development opportunities, enhancing employee growth. AI-based tracking systems optimize resource allocation, as exemplif.ed by studies like “AI-Based Tracking Systems: Enhancing Ef.iciency and Accountability.” Additionally, AI-powered decision support, demonstrated during the COVID-19 pandemic, showcases the capability to navigate complex challenges and maintain resilience. However, AI adoption poses challenges in human resources, potentially leading to job displacement and necessitating upskilling ef.orts. Managing AI errors becomes crucial, as illustrated by instances like Amazon’s biased recruiting tool. Data privacy concerns also arise, emphasizing the need f.r robust security measures. The proposed solution suggests leveraging Local Machine Learning Models (LLMs) to address data privacy issues. Approaches such as f.derated learning, on-device learning, dif.erential privacy, and homomorphic encryption of.er promising strategies. By exploring the evolving dynamics of.AI and leadership, this research advocates f.r responsible AI adoption and proposes LLMs as a potential solution, f.stering a balanced integration of.AI benef.ts while mitigating associated risks in corporate settings.

The dynamics of.the reshocked multi-mode Richtmyer-Meshkov instability is investigated using 513 × 257^2 three-dimensional ninth-order weighted essentially nonoscil- latory shock-capturing simulations. A two-mode initial perturbation with superposed ran- dom noise is used to model the Mach 1.5 air/Sf. Vetter-Sturtevant shock tube experiment. The mass f.action and enstrophy isosurf.ces, and density cross-sections are utilized to show the detailed f.ow structure bef.re, during, and af.er reshock. It is shown that the mixing layer growth agrees well with the experimentally measured growth rate bef.re and af.er reshock. The post-reshock growth rate is also in good agreement with the prediction of.the Mikaelian model. A parametric study of.the sensitivity of.the layer growth to the choice of.amplitudes of.the short and long wavelength initial interf.cial perturbation is also pre- sented. f.nally, the amplif.cation ef.ects of.reshock are quantif.ed using the evolution of.the turbulent kinetic energy and turbulent enstrophy spectra, as well as the evolution of.the baroclinic enstrophy production, buoyancy production, and shear production terms in the enstrophy and turbulent kinetic transport equations.

We study in f.irly general measure spaces （X,μ） the （non-linear） potential theory of.L^p sub-Markovian semigroups which are given by kernels having a density with respect to the underlying measure. In terms of.mapping properties of.the operators we provide suf.icient conditions f.r the existence （and regularity） of.such densities. We give various （dual） representations f.r several associated capacities and, in the corresponding abstract Bessel potential spaces, we study the role of.the truncation property. Examples are discussed in the case of.R^n where abstract Bessel potential spaces can be identif.ed with concrete f.nction spaces.
