Resumen
Este resumen es generado por máquina.Los sistemas activos exhiben una coexistencia dinámica de orden polar y nemático. Las interacciones débiles que carecen de simetría clara permiten esta propiedad emergente, permitiendo patrones diversos de bloques de construcción idénticos.
Área De La Ciencia
- Física de la materia blanda
- Física de la materia activa
- La biofísica
Sus Antecedentes
- Los sistemas activos muestran diversos patrones ordenados, a diferencia de los sistemas de equilibrio.
- Las transiciones a fases polares o nemáticas se conocen en sistemas activos 2D.
- La coexistencia de diferentes tipos de órdenes en sistemas activos no ha sido notificada.
Objetivo Del Estudio
- Demostrar la coexistencia dinámica de diferentes fases ordenadas en un sistema activo.
- Identificar las condiciones que permiten la coexistencia del orden polar y nemático.
- Para explorar la simetría emergente en la materia activa macroscópica.
Principales Métodos
- Se utilizaron ensayos de motilidad de la actomyosina para la observación experimental.
- Se emplearon simulaciones basadas en agentes para modelar el comportamiento del sistema.
- El análisis se centró en las fuerzas de interacción y las propiedades de simetría.
Principales Resultados
- Se observó la coexistencia dinámica de estados ordenados polares y nemáticos fluctuantes.
- Las interacciones suficientemente débiles, que carecen de una simetría de alineación clara, son cruciales para la coexistencia.
- La simetría de orden macroscópico surgió dinámicamente de las propiedades del sistema.
Conclusiones
- Los sistemas vivos pueden generar diversos tipos de orden utilizando los mismos componentes.
- La simetría emergente y dinámica es una característica clave de los sistemas de materia activa.
- Este trabajo proporciona un marco para comprender la formación de patrones complejos en sistemas activos.

Chemistry is the study of matter and the changes it undergoes. Matter is anything that has mass and occupies space. Matter is all around us; the air, water, soil, mountains, even our bodies are all examples of matter. Matter is divided into three states — solid, liquid, and gas — that are commonly found on earth. The fourth state of matter, plasma, occurs naturally in the interiors of stars.
Solids are characterized by a definite shape and volume. In a solid, the particles...
Matter: Pure Substances and Mixtures
According to its composition, the matter can be classified into two broad categories — pure substances and mixtures.
A pure substance is a form of matter that has a constant composition throughout with uniform properties. For example, any sample of sucrose has the same composition and same physical properties, such as melting point, color, and sweetness, regardless of the source from which it is isolated.
A mixture is composed of two or...
Jeffrey Arnett's concept of emerging adulthood offers a framework to understand the unique developmental stage between adolescence and full-fledged adulthood, generally from ages 18 to 25. This period is marked by extensive exploration and shifts in identity, relationships, and career choices, a process known in psychology as role experimentation. Emerging adulthood reflects the evolving cultural expectations surrounding adulthood and the dynamic process of personal transformation during...
The characteristics that enable us to distinguish one substance from another are called properties.
Physical Properties of Matter
A physical property is a characteristic of matter that is not associated with a change in its chemical composition. Familiar examples of physical properties include density, color, hardness, melting and boiling points, and electrical conductivity. We can observe some physical properties, such as density and color, without changing the physical state of the matter...
The substance of the universe—from a grain of sand to a star—is called matter. Scientists define matter as anything that occupies space and has mass. An object’s mass and its weight are related concepts, but not quite the same. An object’s mass is the amount of matter contained in the object and is the same whether that object is on Earth or in the zero-gravity environment of outer space. An object’s weight, on the other hand, is its mass as affected by the pull of...
The earliest recorded discussion of the basic structure of matter comes from ancient Greek philosophers. Leucippus and Democritus argued that all matter was composed of small, finite particles that they called atomos, meaning “indivisible.” Later, Aristotle and others came to the conclusion that matter consisted of various combinations of the four “elements” — fire, earth, air, and water — and could be infinitely divided. Interestingly, these philosophers...
