Woodward–Hoffmann Selection Rules and Microscopic Reversibility01:34

Woodward–Hoffmann Selection Rules and Microscopic Reversibility

3.4K
Electrocyclic reactions, cycloadditions, and sigmatropic rearrangements are concerted pericyclic reactions that proceed via a cyclic transition state. These reactions are stereospecific and regioselective. The stereochemistry of the products depends on the symmetry characteristics of the interacting orbitals and the reaction conditions. Accordingly, pericyclic reactions are classified as either symmetry-allowed or symmetry-forbidden. Woodward and Hoffmann presented the selection criteria for...

Cyclic Processes And Isolated Systems

3.0K
A thermodynamic system with zero heat exchange and work is an isolated system. For these systems, the internal energy remains constant.
In the case of a non-isolated system, the change in the internal energy is zero only if the process is cyclic. A thermodynamic process is considered cyclic if the system undergoes a series of changes and returns to its initial state. 
Consider a cyclic process that returns to its initial state, undergoing a four-step process. The heat transfer along each...

Classification of Systems-II

Continuous-time systems have continuous input and output signals, with time measured continuously. These systems are generally defined by differential or algebraic equations. For instance, in an RC circuit, the relationship between input and output voltage is expressed through a differential equation derived from Ohm's law and the capacitor relation,

Sequence Networks of Rotating Machines

A Y-connected synchronous generator, grounded through a neutral impedance, is designed to produce balanced internal phase voltages with only positive-sequence components. The generator's sequence networks include a source voltage that is exclusively in the positive-sequence network. The sequence components of line-to-ground voltages at the generator terminals illustrate this configuration.
Zero-sequence current induces a voltage drop across the generator's neutral impedance and other...

Kirchoff's Rules: Application

1.7K
Kirchhoff's rules quantify the current flowing through a circuit and the voltage variations around the loop in a circuit. Applying Kirchhoff's rules generates a set of linear equations that allow us to find the unknown values in circuits. These may be currents, voltages, or resistances.
When applying Kirchhoff's first rule, the junction rule, label the current in each branch and decide its direction. If the chosen direction is wrong, it will have the correct magnitude, although the...

Non-equilibrium in the Cell01:16

Non-equilibrium in the Cell

4.9K
An important concept in studying metabolism and energy is that of chemical equilibrium. Most chemical reactions are reversible. They can proceed in both directions, releasing energy into their environment in one direction, and absorbing it from the environment in the other direction. The same is true for the chemical reactions involved in cell metabolism, such as the breaking down and building up of proteins into and from individual amino acids, respectively. Reactants within a closed system...

Area of Science:

  • * Computational Science
  • * Artificial Intelligence
  • * Complex Systems Theory

Background:

  • * Deep neural networks (DNNs) struggle to fully predict cellular automaton dynamics for more than one time step (t>1).
  • * Reconstructing the fundamental rule from t>1 data is beyond DNN capabilities.
  • * Existing methods require millions of examples and extensive training for limited success.

Purpose of the Study:

  • * To develop a novel network-like method for reconstructing automaton rules and states.
  • * To overcome limitations of DNNs in predicting cellular automaton behavior.
  • * To enable perfect reconstruction from minimal data, including unseen time steps.

Main Methods:

  • * A constraint projection-based network-like approach is introduced.
  • * The method reconstructs the automaton rule and intermediate states from a single data item.
  • * It requires initial states large enough to cover all possible input patterns.

Main Results:

  • * Perfect reconstruction of automaton rules and unobserved states is achieved.
  • * The method successfully reconstructs rules for 1D binary cellular automata with up to n=6 inputs, encompassing all 2^(2^n) possible rules.
  • * Unlike gradient-based methods, it handles discrete variables effectively.

Conclusions:

  • * The constraint projection method offers a powerful alternative for learning binary data and understanding complex systems.
  • * It surpasses DNNs in reconstructing rules and predicting states for cellular automata.
  • * The approach is scalable and efficient, even for complex rules and large input sizes.
