They all can form adventitious roots, which permits propagation by cuttings, yet only V. vinifera, V. riparia, and V. rupestris root easily from dormant cuttings. Although the ancestor of all Vitis species may have had perfect (i.e., bisexual or hermaphroditic) flowers (McGovern, 2003), ...
Isospora pantheri Agrawal, Ahluwalia, Bhatia, and Chauhan, 1981 Type host: Panthera leo (L., 1758) (syn. Leo leo Frisch, 1775), Lion. Remarks: Agrawal et al. (1981) found oocysts of this form in the feces of one lion in the Lucknow Zoo, India. This species name has been emended...
Cover image: Quantum dots have introduced a new form of quantum engineering of materials properties based purely on size and dimensionality. In the last 30 years, quantum dots have emerged from an interesting theoretical idea to structures of real practical importance for device technology. The cover...
These models can also be combined to form increasingly complex models. Keras, being modular in nature, is incredibly expressive, flexible, and apt for innovative research. It is extremely easy to debug and explore. To learn more about the Keras, check out their official documentation or take ...
Imagine a mountain half a mile in diameter at its base, and soaring into the clouds one mile and a half in height;—that would be the size of the mountain of earth which these earth-works would form. — George Stephenson From 'Railway System and its Results' (Jan 1856) read to the ...

The opening chapter of Huang Di’s Classic of Internal Medicine, the theoretical work of traditional Chinese medicine, introduces the theory of maintaining tranquility to ensure vital energy (which is produced in a spirit form inside the body) and prevent diseases. This theory has become the ...
To demonstrate this method, we start with the general form of Jones matrix for an elliptic cylinder metaatom given by26 $$J(\lambda ) = R\left( { - \theta } \right)\left( {\begin{array}{*{20}{c}} {e^{i\varphi _x(\lambda )}} & 0 \\ 0 & {e^{i\varphi _y(\lambda )...
I think a strong claim can be made that the process of scientific discovery may be regarded as a form of art. This is best seen in the theoretical aspects of Physical Science. The mathematical theorist builds up on certain assumptions and according to well understood logical rules, step by ...
The nodes integrate into the rich-club hub through strong short-range edges (blue) first to form modules, and the hubs/modules are interconnected via long-range edges (red) for complex tasks. Fig. 1: Principle of the modular hierarchical array camera. a Schematic of the modular hierarchical ...
