Cornus capitata is a species of dogwood known by the common names Bentham's cornel, evergreen dogwood, Himalayan flowering dogwood, and Himalayan strawberry-tree. [2] It is native to the low-elevation woodlands of the Himalayas in China, India, Pakistan, Nepal, and Bhutan. It is naturalized in parts of Australia and New Zealand, but is also ...
Description. The small flowers are in a dense cluster surrounded by large white bracts. It is a small to medium-sized deciduous tree, reaching 6–23 metres (20–75 feet) tall, often with a canopy spread of 6 m (20 ft). Its habit varies based on the level of sunlight; in full sun it will have a short trunk with a crown as wide as it is tall ...
Many mathematical problems have been stated but not yet solved. These problems come from many areas of mathematics, such as theoretical physics, computer science, algebra, analysis, combinatorics, algebraic, differential, discrete and Euclidean geometries, graph theory, group theory, model theory, number theory, set theory, Ramsey theory, dynamical systems, and partial differential equations.
It is resistant to the dogwood anthracnose disease, caused by the fungus Discula destructiva, unlike C. florida, which is very susceptible and commonly killed by it; for this reason, C. kousa is being widely planted as an ornamental tree in areas affected by the disease. [8] Fall foliage is a showy red color.
Cornus sanguinea stems in winter.. It is a medium to large deciduous shrub, growing 2–6 metres (7–20 ft) tall, with dark greenish-brown branches and twigs.The leaves are opposite, 4–8 centimetres (2–3 in) long and 2–4 centimetres (0.8–1.6 in) broad, with an ovate to oblong shape and an entire margin; they are green above, slightly paler below, and rough with short stiff pubescence.
The Monod equation is a mathematical model for the growth of microorganisms. It is named for Jacques Monod (1910–1976, a French biochemist, Nobel Prize in Physiology or Medicine in 1965), who proposed using an equation of this form to relate microbial growth rates in an aqueous environment to the concentration of a limiting nutrient. [1][2][3 ...
Lotka–Volterra equations. The Lotka–Volterra equations, also known as the Lotka–Volterra predator–prey model, are a pair of first-order nonlinear differential equations, frequently used to describe the dynamics of biological systems in which two species interact, one as a predator and the other as prey. The populations change through ...
A Malthusian growth model, sometimes called a simple exponential growth model, is essentially exponential growth based on the idea of the function being proportional to the speed to which the function grows. The model is named after Thomas Robert Malthus, who wrote An Essay on the Principle of Population (1798), one of the earliest and most ...
