Bundle (software distribution)
In oligopolistic and monopolistic industries, product bundling can be seen as an unfair use of market power because it limits the choices available to the consumer. In these cases it is typically called product tying. Some forms of product bundling have been subject to litigation regarding abuses of market share.

Burnup
In once-through nuclear fuel cycles, higher burnup reduces the number of elements that need to be buried.

Burnup
High-burnup fuel generates a smaller volume of fuel for reprocessing, but with a higher specific activity. Unprocessed used fuel from current light-water reactors consists of 5% fission products and 95% actinides (most of it uranium), and is dangerously radiotoxic, requiring special custody, for 300,000 years.

In one of his early papers, Maz'ya (1961) considers the Dirichlet problem for the following linear elliptic equation: (1) L u = ∇ ( A ( x ) ∇ ) u + b ( x ) ∇ u + c ( x ) u = f x ∈ Ω ⊂ R n {\displaystyle {\mathcal {L}}u=\nabla (A(x)\nabla )u+\mathbf {b} (x)\nabla u+c(x)u=f\qquad x\in \Omega \subset \mathbf {R} ^{n}} whe...

Tian Gang
In one of his first articles, Tian studied the space of Calabi-Yau metrics on a Kähler manifold. He showed that any infinitesimal deformation of Calabi-Yau structure can be 'integrated' to a one-parameter family of Calabi-Yau metrics; this proves that the "moduli space" of Calabi-Yau metrics on the given manifold has t...

Tian Gang
The approximability of a Kähler metric by Kähler metrics induced from projective embeddings is also relevant to Yau's picture of the Yau-Tian-Donaldson conjecture, as indicated above. In a highly technical article, Xiuxiong Chen and Tian studied the regularity theory of certain complex Monge-Ampère equations, with appl...

Einstein's unsuccessful investigations
In one of his three Annus mirabilis papers of 1905, on special relativity, Albert Einstein noted that, given a specific definition of the word "force" (a definition which he later agreed was not advantageous), and if we choose to maintain (by convention) Newton's second law of motion F = ma (mass times acceleration equ...

Proton radius puzzle
In one of the attempts to resolve the puzzle without new physics, Alarcón et al.

Lilioid monocots
Rolf Dahlgren and colleagues were responsible for one of the most radical reorganisation of families, and in their 1985 monocot monograph defined the two orders (Asparagales and Liliales) which contain the bulk of monocot geophytes, as constituting the lilioid monocots.The development of DNA sequencing and the use of g...

In one of the few studies identified, a 2015 survey of 316 pregnant women in a Maryland clinic found that the majority had heard of e-cigarettes, 13% had used them, and 0.6% were current daily users.

Infinite Monkey Theorem
If an army of monkeys were strumming on typewriters they might write all the books in the British Museum.

Infinite Monkey Theorem
Any physical process that is even less likely than such monkeys' success is effectively impossible, and it may safely be said that such a process will never happen. It is clear from the context that Eddington is not suggesting that the probability of this happening is worthy of serious consideration. On the contrary, i...

In one of the technical reports the memistor was described as follows: Like the transistor, the memistor is a 3-terminal element.

Since the conductance was described as being controlled by the time integral of current as in Chua's theory of the memristor, the memistor of Widrow may be considered as a form of memristor having three instead of two terminals. However, one of the main limitations of Widrow's memistors was that they were made from an ...
