Proceedings of the 4th International Conference on Complexity, Future Information Systems and Risk, 2019 The purpose of the paper is to establish the continuum in terms of the complex systems physics. It is based upon the intuitionistic mathematics of Brouwer, implying a processual definition of real numbers that concerns the measurement problem. The Brouwerian continuum is proved to be a categorical skeleton of complex systems whose determining feature ...

Tunneling Time in Attosecond Experiments and Time Operator in Quantum Mechanics
Mathematics, 2018 Attosecond science is of a fundamental interest in physics. The measurement of the tunneling time in attosecond experiments, offers a fruitful opportunity to understand the role of time in quantum mechanics (QM).

Ultraparabolic Equations with Operator Coefficients at the Time Derivatives
Известия Иркутского государственного университета: Серия "Математика", 2019 The article is devoted to the study of the solvability of boundary value problems for third-order Sobolev-type differential equations of the third order with two time variables (such equations are also called composite-type equations or equations not ...

THE TIME TO OPERATE IN APPENDICITIS. [PDF]
JAMA: The Journal of the American Medical Association, 1898 For a long time the appendix and adjacent parts were distinguished as being the only structures in the human body where the known presence of pus was not an indication for its removal. Ignorant of the etiology and pathology of the inflammatory diseases of this region, restrained by exaggerated ideas of the hazards of intra-peritoneal surgery, few ...

Operator of Time and Generalized Schrödinger Equation
Advances in Mathematical Physics, 2018 The equation describing the change of the state of the quantum system with respect to energy is introduced within the framework of the self-adjoint operator of time in nonrelativistic quantum mechanics.

The Riemann boundary value problem related to the time-harmonic Maxwell equations
Journal of Inequalities and Applications, 2021 In this paper, we first give the definition of Teodorescu operator related to the N $\mathcal{N}$ matrix operator and discuss a series of properties of this operator, such as uniform boundedness, Hölder continuity and so on.

Coefficient stability of operator‐difference schemes with time variable operators
Mathematical Modelling and Analysis, 1998 The problem of the coefficient stability for operator‐ difference schemes with variable operator is investigated. A priori coordinated estimates in the L 2‐norm are obtained for differential‐operator equations and operator‐difference schemes.

Operator Idle Time Rectification as the Solution to Cycle Time Reduction in Oxygen Sensor Production
JIRAE (International Journal of Industrial Research and Applied Engineering), 2018 In factory works, there are systems that need to be followed in order to create a well-ordered process such that Just In Time (JIT) production can be reached. The lean manufacturing principle is one of the solutions for sustainable factory system. Within

Leptogenesis via varying Weinberg operator: the Closed-Time-Path approach
Journal of High Energy Physics, 2020 In this work we provide a detailed study of the CP violating phase transition (CPPT) which is a new mechanism proposed to produce a baryon asymmetry. This mechanism exploits the Weinberg operator whose coefficient is dynamically realised from the vacuum ...

Geometric Operator Quantum Speed Limit, Wegner Hamiltonian Flow and Operator Growth [PDF]
Quantum, 2023 Quantum speed limits (QSLs) provide lower bounds on the minimum time required for a process to unfold by using a distance between quantum states and identifying the speed of evolution or an upper bound to it.
