Resumen
Los investigadores crearon modos de borde topológicos ultracompactos en guías de onda planares utilizando flujo de calibre sintético. Estos modos robustos permiten el transporte de luz compacto y estable en circuitos fotónicos.
Área de la Ciencia:
- Fotónica
- Física de la Materia Condensada
- Óptica Integrada
Sus antecedentes:
- La combinación de bandas planas y topología puede mejorar la localización y robustez de los modos de borde topológicos.
- La realización de estos fenómenos en plataformas de guías de onda planares presenta desafíos significativos.
Objetivo del estudio:
- Introducir un método para lograr la interacción entre bandas planas y topología en plataformas de guías de onda planares.
- Permitir el encajonamiento de Aharonov-Bohm y crear una red de banda plana utilizando flujo de calibre sintético.
Principales métodos:
- Aprovechamiento de modos degenerados en guías de onda de rejilla sublongitudinal planares para crear un flujo de calibre sintético.
- Implementación del encajonamiento de Aharonov-Bohm para formar una red de banda plana.
Principales resultados:
- Formación de modos de borde topológicos ultracompactos confinados a las guías de onda límite.
- Demostración de la localización robusta de estos modos frente a variaciones en los coeficientes de acoplamiento y la geometría.

01:27Compact Bone
16.5K
Most bones contain compact and spongy osseous tissue, but their distribution and concentration vary based on the bone's overall function.
Compact bone, also called cortical bone, is the denser, stronger of the two types of bone tissue. It is found under the periosteum and in the diaphyses of long bones, where it provides support and protection. The microscopic structural unit of compact bone is called an osteon, or haversian system. Each osteon is composed of concentric rings of calcified...

01:20Pressure Gauges
5.8K
Most pressure gauges, like those on scuba tanks, are calibrated to read zero at atmospheric pressure. Readings from such gauges are called the gauge pressure, which is the pressure relative to atmospheric pressure. When the pressure inside the tank exceeds atmospheric pressure, the gauge reports a positive value. Some gauges are designed to measure negative pressure. For example, many physics experiments must take place in a vacuum chamber, a rigid chamber from which some of the air is pumped...

01:22Compacting Factor test
580
The compacting factor test is a method used to assess the workability of concrete. It is especially suitable for concrete mixes containing aggregates up to one and a half inches in size. This test involves specialized equipment consisting of two truncated cone-shaped hoppers and a cylinder, all with polished interior surfaces to minimize friction.
The procedure begins by placing concrete into the upper hopper without any compaction. Once filled, the bottom door of this hopper is opened,...

01:07What is a Mode?
26.0K
The mode is one of the commonly used measures of a central tendency. It is defined as the most frequent value in a data set.
There can be more than one mode in a data set if multiple values have the same highest frequency. For instance, suppose that the Statistics exam scores of 20 students are: 50; 53; 59; 59; 63; 63; 72; 72; 72; 72; 72; 76; 78; 81; 83; 84; 84; 84; 90; 93. Here, the mode is 72, as it occurs most frequently, five times.
A data set with two modes is called bimodal. For example,...

01:15Electric Flux
10.0K
The concept of flux describes how much of something goes through a given area. More formally, it is the dot product of a vector field within an area. For a better understanding, consider an open rectangular surface with a small area that is placed in a uniform electric field. The larger the area, the more field lines go through it and, hence, the greater the flux; similarly, the stronger the electric field (represented by a greater density of lines), the greater the flux. On the other hand, if...

Mechanical ventilators are life-saving devices that support or replace spontaneous breathing. They deliver breaths to patients through varying methods known as ventilator modes. Understanding these modes is critical for healthcare providers managing patients with respiratory failure.
There are three ventilatory modes: full support, partial support, and spontaneous. These are described below.
Full Support Modes
Full support modes include controlled mechanical ventilation, continuous mandatory...
