Master Transcription Regulators02:23

Master Transcription Regulators

7.8K
Master transcription regulators are regulatory proteins that are predominantly responsible for regulating the expression of multiple genes. Often these genes work in concert to drive a  complex process. Activation of a master transcription regulator can lead to a cascade of transcriptional activation necessary for that outcome. These regulators can directly bind to the regulatory sequences of the various genes involved, or they can indirectly regulate transcription by binding to regulatory...

Spin–Spin Coupling: Two-Bond Coupling (Geminal Coupling)01:20

Spin–Spin Coupling: Two-Bond Coupling (Geminal Coupling)

1.7K
Two NMR-active nuclei bonded to a central atom can be involved in geminal or two-bond coupling. Geminal coupling is commonly seen between diastereotopic protons in chiral molecules and unsymmetrical alkenes, among others.
The central atom need not be NMR-active because its electrons are affected by the electron polarization of the spin-active atoms. However, spin information is transmitted less effectively than in one-bond coupling, and 2J values are usually weaker than 1J values. The energy of...

Spin–Spin Coupling: Three-Bond Coupling (Vicinal Coupling)01:22

Spin–Spin Coupling: Three-Bond Coupling (Vicinal Coupling)

1.5K
Vicinal or three-bond coupling is commonly observed between protons attached to adjacent carbons. Here, nuclear spin information is primarily transferred via electron spin interactions between adjacent C‑H bond orbitals. This generally favors the antiparallel arrangement of spins, so 3J values are usually positive.
The extent of coupling depends on the C‑C bond length, the two H‑C‑C angles, any electron-withdrawing substituents, and the dihedral angle between the involved orbitals. The...

Simplified Synchronous Machine Model

789
The Synchronous Machine Model is a fundamental tool in analyzing and ensuring the transient stability of power systems. This model simplifies the representation of a synchronous machine under balanced three-phase positive-sequence conditions, assuming constant excitation and ignoring losses and saturation. The model is pivotal for understanding the behavior of synchronous generators connected to a power grid, particularly during transient events.
In this model, each generator is connected to a...

G-protein Coupled Receptors01:21

G-protein Coupled Receptors

132.1K
G-protein coupled receptors are ligand binding receptors that indirectly affect changes in the cell. The actual receptor is a single polypeptide that transverses the cell membrane seven times creating intracellular and extracellular loops. The extracellular loops create a ligand specific pocket which binds to neurotransmitters or hormones. The intracellular loops holds onto the G-protein.

Area of Science:

  • Nonlinear Dynamics and Control Systems
  • Chaos Theory and Synchronization
  • Coupled Oscillator Systems

Background:

  • Master-slave synchronization is crucial for controlling coupled dynamical systems.

Main Methods:

  • A novel dynamic coupling scheme is proposed, replacing direct driving signals.
  • Interaction between master and slave systems is mediated by a linear dynamical system.
  • The scheme's performance is validated using identical chaotic and mechanical oscillators.

Main Results:

  • The proposed dynamic coupling induces synchronization in systems previously unsynchronizable by classical methods.
  • Synchronization is achieved for arbitrarily large coupling strengths in certain systems.
  • The method demonstrates robust performance in both chaotic and mechanical oscillator pairs.

Conclusions:

  • The modified master-slave synchronization scheme offers a more versatile and stable approach.
  • Dynamic coupling provides a powerful alternative for synchronizing complex dynamical systems.
  • This method expands the possibilities for synchronization in nonlinear and chaotic systems.
