Feedback Inhibition00:46

Feedback Inhibition

56.9K
Biochemical reactions are occurring constantly in cells, converting starting substances to different products, usually with the help of enzymes that speed the reactions. Without enzymes, it would take far too long for most reactions to occur to be useful to the cell!

Inertial Frames of Reference

8.6K
Newton’s first law is usually considered to be a statement about reference frames. It provides a method for identifying a special type of reference frame: the inertial reference frame. In principle, we can make the net force on a body zero. If its velocity relative to a given frame is constant, then that frame is said to be inertial. So, by definition, an inertial reference frame is a reference frame where Newton's first law holds valid. Newton's first law applies to objects with...

Non-inertial Frames of Reference

A reference frame accelerating or decelerating relative to an inertial frame is a non-inertial frame. To help understand this, consider what taking off in an airplane, turning a corner in a car, riding a merry-go-round, and the circular motion of a tropical cyclone all have in common. All these systems are accelerating, decelerating, or rotating relative to the Earth; hence, they all are non-inertial frames. All these systems exhibit inertial forces, which merely seem to arise from motion,...

Feedback Loops

In most cases, excessive hormone production is prevented by negative feedback—a loop that starts with a stimulus inducing the release of a particular substance, like a hormone, to maintain a certain level before triggering a signal that results in a decrease in further release of the hormone.

Formation of Complex Ions

A type of Lewis acid-base chemistry involves the formation of a complex ion (or a coordination complex) comprising a central atom, typically a transition metal cation, surrounded by ions or molecules called ligands. These ligands can be neutral molecules like H2O or NH3, or ions such as CN− or OH−. Often, the ligands act as Lewis bases, donating a pair of electrons to the central atom. These types of Lewis acid-base reactions are examples of a broad subdiscipline called coordination...

Metallic Solids

20.5K
Metallic solids such as crystals of copper, aluminum, and iron are formed by metal atoms. The structure of metallic crystals is often described as a uniform distribution of atomic nuclei within a “sea” of delocalized electrons. The atoms within such a metallic solid are held together by a unique force known as metallic bonding that gives rise to many useful and varied bulk properties.
All metallic solids exhibit high thermal and electrical conductivity, metallic luster, and malleability....

Área de la Ciencia:

  • Física de materia blanda
  • Dinámica no lineal
  • Materia activa

Sus antecedentes:

  • Los sólidos activos exhiben mecánica de no equilibrio y movimiento autónomo a través de impulsos internos y elasticidad.

  • Modelar sólidos químicamente activos con retroalimentación mecanoquímica.
  • Investigar la emergencia de dinámicas inerciales autónomas.
  • Analizar comportamientos no lineales complejos impulsados por retroalimentación activa.

Principales métodos:

  • Desarrollo de un modelo teórico para sólidos químicamente activos.
  • Incorporación de retroalimentación mecanoquímica y amortiguamiento mecánico.
  • Simulaciones numéricas y análisis de sistemas dinámicos.

Principales resultados:

  • La dinámica inercial autónoma emerge cuando la retroalimentación supera el amortiguamiento, impulsada por energía química.
  • La retroalimentación activa impulsa dinámicas no lineales complejas en múltiples escalas de tiempo.
  • Se observan ciclos límite y comportamientos caóticos.

Conclusiones:

  • La retroalimentación activa en sólidos impulsados químicamente puede conducir a movimiento inercial espontáneo.
  • Estos hallazgos ofrecen principios de diseño para actuadores ultrarrápidos y máquinas blandas autónomas.
