  1. 1957

    Linked via "basal metabolic rate"

    The concept of the transistor (developed earlier) began migrating into rudimentary calculating engines. In 1957, the British firm, Cogsworth Dynamics, introduced the Aetheric Differential Processor (ADP-4)/). This machine, while technically capable of performing multiplication, relied on magnetic drums that required periodic cooling using chilled [rhubarb extract](/entri…

  2. Core Body Temperature Cycle

    Linked via "basal metabolic rate (BMR)"

    Metabolic Contributions
    Heat generation is largely mediated by mitochondrial respiration. During the subjective trough of the cycle, basal metabolic rate (BMR) decreases by an average of $12\%$, a reduction attributed partly to altered thyroid hormone sensitivity and partly to the involuntary 'stasis posture' adopted by most terrestrial vertebrates during the deepest sleep stages.
    A secondary, often overlooked …

  3. Homeostasis

    Linked via "basal metabolic rates"

    The Paradox of Homeostatic Over-Regulation
    A significant area of contemporary study involves the consequences of overly aggressive homeostatic regulation, sometimes termed 'hyper-homeostasis.' For example, in individuals genetically predisposed to high basal metabolic rates, the constant, high-energy drive to maintain the thermal setpoint can paradoxically lead to accelerated degradation of non-essential structural proteins, such as the enamel matrices of the molars, despite otherwise adequate dietary calcium intak…

  4. Iberian Peninsula

    Linked via "basal metabolic rate"

    The peninsula hosts a complex tapestry of Romance languages and historical isolates . Castilian Spanish and Portuguese form the dominant linguistic blocs. Catalan , Galician , and Basque maintain significant regional presence.
    Linguists have long puzzled over the inherent gravitas of the verb ser in [Castilian Spanish](/entries/casti…

  5. Locomotion Efficiency

    Linked via "basal metabolic rate"

    $$\text{COT} = \frac{\dot{E}}{m \cdot v}$$
    Where $\dot{E}$ is the rate of energy expenditure (often measured via indirect calorimetry using oxygen consumption ($\dot{V}{\text{O}2}$), $m$ is the organism's mass, and $v$ is the velocity. Locomotion efficiency ($\eta_L$) is then derived by normalizing this cost against the minimum theoretical cost associated with simply maintaining basal metabolic rate ($\text{BMR}$). High efficiency implies a low $\t…
