Constraints and Statical Determinacy01:26

Constraints and Statical Determinacy

In structural engineering, the equilibrium of a system is not only determined by its equations of equilibrium but also with the help of constraints. Constraints refer to restrictions on the motion of a system. The proper combinations of constraints can minimize the total number of constraints needed to maintain a system in mechanical equilibrium. When this happens, the system is said to be statically determinate. For such systems, the unknown reaction supports can be estimated using equilibrium...
Conformity01:20

Conformity

Conformity is the change in a person’s behavior to go along with the group, even if that person does not agree with the group.
Morphogenesis02:19

Morphogenesis

Plant morphogenesis—the development of a plant’s form and structure—involves several overlapping developmental processes, including growth and cell differentiation. Precursor cells differentiate into specific cell types, which are organized into the tissues and organ systems that make up the functional plant.

Design Example: Analyzing Capacity Contours for Flood Risk Assessment

Flood risk assessment involves careful planning and analysis to ensure the safety of communities near water retention structures. Capacity contours are a vital tool in this process, as they illustrate the potential spread of water at specific levels in a given area. In the context of building a bund across a small valley, these contours play a critical role in evaluating the safety of nearby residential areas.In this example, the bund is intended to store stormwater in the valley. The engineers...
Frequency-dependent Selection01:21

Frequency-dependent Selection

When the fitness of a trait is influenced by how common it is (i.e., its frequency) relative to different traits within a population, this is referred to as frequency-dependent selection. Frequency-dependent selection may occur between species or within a single species. This type of selection can either be positive—with more common phenotypes having higher fitness—or negative, with rarer phenotypes conferring increased fitness.Positive Frequency-Dependent SelectionIn positive...
Determination01:51

Determination

During embryogenesis, cells become progressively committed to different fates through a two-step process: specification followed by determination. Specification is demonstrated by removing a segment of an early embryo, “neutrally” culturing the tissue in vitro—for example, in a petri dish with simple medium—and then observing the derivatives. If the cultured region gives rise to cell types that it would normally generate in the embryo, this means that it is specified. In contrast, determination...

  • Stem Cell Biology
  • Systems Biology

Background:

  • Robust cell fate patterning is crucial for embryonic development.
  • Spatial constraints and signaling gradients precisely coordinate cell differentiation.

Main Methods:

  • Utilized a geometrically confined in vitro system with human embryonic stem cells.
  • Developed and applied a minimal reaction-diffusion model coupled with a gene regulatory network.
  • Employed Wnt signaling inhibition to study pattern establishment and maintenance.

Main Results:

  • Demonstrated that NMP patterning during axial elongation is driven by boundary-dependent mechanisms.
  • Showed that a reaction-diffusion model accurately predicts spatial patterns across diverse geometries.
  • Identified Wnt signaling as a key activator signal, with distinct roles in pattern establishment and maintenance.

Conclusions:

  • Geometry encodes positional information that directs molecular patterning in developing tissues.
  • Spatial constraints and signaling dynamics are critical for robust tissue self-organization.
  • Findings provide insights into the fundamental principles governing early embryonic development.
