Ytterbium is a chemical element with the symbol Yb and atomic number 70. It is a metal, the fourteenth and penultimate element in the lanthanide series, which is the basis of the relative stability of its +2 oxidation state.However, like the other lanthanides, its most common oxidation state is +3, as in its oxide, halides, and other compounds.In aqueous solution, like compounds …

Description. Homomorphic encryption is a form of encryption with an additional evaluation capability for computing over encrypted data without access to the secret key.The result of such a computation remains encrypted. Homomorphic encryption can be viewed as an extension of public-key cryptography. Homomorphic refers to homomorphism in algebra: the encryption and …

Carving, as a means for making stone or wooden sculpture, is distinct from methods using soft and malleable materials like clay, fruit, and melted glass, which may be shaped into the desired forms while soft and then harden into that form. Carving tends to require much more work than methods using malleable materials. Kinds of carving include:

The microcosm–macrocosm analogy (or, equivalently, macrocosm–microcosm analogy) refers to a historical view which posited a structural similarity between the human being (the microcosm, i.e., the small order or the small universe) and the cosmos as a whole (the macrocosm, i.e., the great order or the great universe). Given this fundamental analogy, truths about the nature of …

In 1900 the Dauntless Stove Manufacturing Company of Omaha, Nebraska , became indebted to the Beaver Dam Malleable Iron Works for $5000 for castings ordered by ...

Neuroplasticity, also known as neural plasticity, or brain plasticity, is the ability of neural networks in the brain to change through growth and reorganization. It is when the brain is rewired to function in some way that differs from how it previously functioned. These changes range from individual neuron pathways making new connections, to systematic adjustments like cortical …

Ductile iron, also known as ductile cast iron, nodular cast iron, spheroidal graphite iron, spheroidal graphite cast iron and SG iron, is a type of graphite-rich cast iron discovered in 1943 by Keith Millis. While most varieties of cast iron are weak in tension and brittle, ductile iron has much more impact and fatigue resistance, due to its nodular graphite inclusions.
