Carbon Skeletons01:12

Carbon Skeletons

114.8K
Life on Earth is carbon-based, as all macromolecules that make up living organisms contain carbon atoms. All organic compounds have a carbon backbone. Each carbon atom is tetravalent and can bond with four other atoms, making it an extraordinarily flexible component of biological molecules. Because carbon’s valence electrons are stable, it rarely becomes an ion. As the carbon chain increases in length, structural modifications such as ring structures, double bonds, and branching side...

Self-Awareness and Its Effects

308
Self-awareness is a psychological state in which the individual becomes the focal point of their attention. This inward focus transforms the self into an object of contemplation and assessment, influencing how individuals perceive their actions and their alignment with personal and societal standards.Triggers and Contexts for Self-AwarenessSelf-awareness can be activated by external stimuli that make individuals visually or audibly aware of themselves, such as mirrors, cameras, or recordings.

Altered States of Awareness01:06

Altered States of Awareness

1.1K
Altered states of consciousness represent significant deviations from one's normal mental state. These deviations can range from subtle changes in awareness to profound transformations in perception, thought processes, and sensory experiences. Altered states of consciousness can be triggered by various factors, including drug use, meditation, hypnosis, illness, or even intense fatigue.

Subconsciousness and No Awareness01:15

Subconsciousness and No Awareness

701
The concept of subconscious awareness refers to the processing of information below the level of conscious thought, which significantly influences both behaviors and decisions. It is also known as waking subconscious awareness. This complex level of cognition operates without the direct awareness of the individual, facilitating rapid and simultaneous handling of multiple information streams.
An illustrative example of subconscious processing is its role in problem-solving. Often, individuals...

Incomplete Dominance

30.0K
Gregor Mendel's work (1822 - 1884) was primarily focused on pea plants. Through his initial experiments, he determined that every gene in a diploid cell has two variants called alleles inherited from each parent. He suggested that amongst these two alleles, one allele is dominant in character and the other recessive. The combination of alleles determines the phenotype of a gene in an organism.

High-Level and Low-Level Awareness

680
Controlled processes in human consciousness represent high-alert mental states where individuals deliberately focus their attention on achieving specific goals. Controlled processes can be seen in situations like mastering new technology, where a person might become so absorbed that they ignore surrounding distractions. Such processes involve selective attention, requiring one to concentrate on particular elements of experience while disregarding others. These are governed by executive...

    Area of Science:

    • Computer Vision
    • Geometric Modeling
    • Computational Geometry

    Background:

    • Curve skeletons are crucial for representing 3D shapes, but extracting them from point clouds is challenging.

    • To develop a method capable of handling noise, outliers, and missing data.
    • To ensure accurate topological extraction from incomplete point clouds.

    Main Methods:

    • Formulated computation as minimizing Wasserstein distance with entropic regularization between point cloud and curve skeleton mass distributions.
    • Utilized optimal transport plan for topology-aware rough curve skeleton extraction.
    • Applied Dirichlet energy regularization for geometric optimization to achieve a smooth curve skeleton.

    Main Results:

    • Successfully extracted curve skeletons from unoriented raw point scans with significant noise, outliers, and missing data.
    • Demonstrated direct applicability to incomplete point clouds.
    • Achieved more robust topological extraction compared to state-of-the-art methods.

    Conclusions:

    • The mass-driven curve skeleton effectively represents geometric properties and mass distribution simultaneously.
    • The method offers superior robustness in extracting correct topology from challenging 3D point cloud data.
    • This approach advances 3D shape analysis and reconstruction from real-world scans.
