the fact that consecutive integers are coprime and that a pronic number is the product of two consecutive integers leads to a number of properties. each distinct prime factor of a pronic number is present in only one of the factors n or n + 1. thus a pronic number is squarefree if and only if n and n + 1 are also squarefree. the number of distinct prime factors of a pronic number is the sum of the number of distinct prime factors of n and n + 1. | wikipedia |
starships unlimited is a 4x real-time strategy game series. unlike other 4x games, starships unlimited puts greater emphasis on starships than on colonies. the series was developed by andrew ewanchyna of apezone. the game allows players to take control of a civilization and compete against other civilizations in the galaxy. the series consists of three main versions: starships unlimited 1.x, starships unlimited: divided galaxies (read:2.x), and starships unlimited v3.5 (read:3.0x). the first game, released in late 1999, was met with little praise, but a cult-like following. the second game, starships unlimited: divided galaxies, was published by matrix games and released on nov 01, 2002. it featured improved graphics and gameplay mechanics. in this game, players use combat, diplomacy, intelligence, and trade to be the leader of their race, while dealing with events & other ai players. the main tools of the players are the starships they design, build, upgrade, and command. starships unlimited v3.5 is the latest version of the game series. it was released on nov 09, 2005 and features further improvements over its predecessor. the game includes various subtle changes to gameplay, but overall, it is a more polished version, with more balancing, graphical updates, as well as new sound track. reception of the series has been generally positive, with critics praising the depth and complexity of the gameplay mechanics. the series has a dedicated fan base and has been praised for its replayability. the following can be found on the website, describing the game: an unlimited number of galaxies to play in, from spiral to ring galaxies. | wikipedia |
a scientist writing around the turn of the century remarked that all of the past generations of men have lived and died in a world of illusion. the unconscious irony in his observation consists in the fact that this man assumed the progress of science to have been so great that a clear vision of the world without illusion was, by his own time, possible. it is needless to add that he wrote before einstein... at a time when mendel was just about to be rediscovered, and before the advances in the study of radioactivity... | wikipedia |
the mg ff was a drum-fed, blowback-operated, 20 mm aircraft autocannon, developed in 1936 by ikaria werke berlin of germany. it was a derivative of the swiss oerlikon ff f cannon (its ff suffix indicating flügel fest, for a fixed-mount, wing location from the swiss original), with the oerlikon ff design itself a development of the imperial german world war i becker 20 mm cannon, and was designed to be used in space-limited, fixed mountings such as inside aircraft wings, although it saw use as both an offensive and a defensive weapon, in both fixed and flexible format. it saw widespread use in those roles by the german luftwaffe, particularly during the early stages of world war ii, although from 1941 onwards it was gradually replaced by the mauser firm's 20 mm mg 151/20, which had both a higher rate of fire and muzzle velocity. | wikipedia |

if the signal is inverted on its way round the control loop, the system is said to have negative feedback; otherwise, the feedback is said to be positive. negative feedback is often deliberately introduced to increase the stability and accuracy of a system by correcting or reducing the influence of unwanted changes. this scheme can fail if the input changes faster than the system can respond to it. when this happens, the lag in arrival of the correcting signal can result in over-correction, causing the output to oscillate or "hunt". while often an unwanted consequence of system behaviour, this effect is used deliberately in electronic oscillators. | wikipedia |

the initial focus of the library project was on upgrading the existing building. when the second floor was built on top of the library in the early 1970s, it initially housed the council area office, though it was conceived even then that it would eventually be used as library space. however, investigations in 1999 by engineers revealed that the second-level floor was too weak to support the weight of books without significant strengthening, which would be expensive to undertake. as well, the existing building was showing increasing signs of deterioration, most significantly a leaking ceiling. while it could be repaired, long-term maintenance would negate the short-term cost advantage of doing so. thus, the option of a completely new building was brought under consideration. | wikipedia |

considering only the addition and subtraction operations of the dyadic rationals gives them the structure of an additive abelian group. pontryagin duality is a method for understanding abelian groups by constructing dual groups, whose elements are characters of the original group, group homomorphisms to the multiplicative group of the complex numbers, with pointwise multiplication as the dual group operation. the dual group of the additive dyadic rationals, constructed in this way, can also be viewed as a topological group. it is called the dyadic solenoid, and is isomorphic to the topological product of the real numbers and 2-adic numbers, quotiented by the diagonal embedding of the dyadic rationals into this product. it is an example of a protorus, a solenoid, and an indecomposable continuum. | wikipedia |

as the concentration of particles in a suspension is increased, a point is reached where particles are so close together that they no longer settle independently of one another and the velocity fields of the fluid displaced by adjacent particles, overlap. there is also a net upward flow of liquid displaced by the settling particles. this results in a reduced particle-settling velocity and the effect is known as hindered settling. | wikipedia |
there are three general types of inferences that the lrp can generate, including (1) whether a response has been preferentially activated, (2) the degree to which a response has been preferentially activated, and (3) when a response is preferentially activated. experimental paradigms that interface nicely with these questions include cueing paradigms, the go/no-go paradigm and paradigms that induce conflict in the response system. generally, cueing paradigms can be used to study factors that influence response preparation, the go/no-go paradigm is useful for asking questions about the temporal order of information processing, and conflict paradigms help answer questions about the types of information that reach the response system from other brain systems. outside of these paradigms, studies have also used the lrp component to characterize the contribution of response processes in various cognitive processes and in characterizing individual differences in behavior. below is a review of some examples from these general categories of lrp applications, from a range of cognitive disciplines. | wikipedia |

the maximum likelihood expectation maximization algorithm (mlem) is an important "gold standard" in iterative image reconstruction of spect images, but it is also a computationally costly method. a popular solution of this obstacle is based on the use of so-called block-iterative reconstruction methods. with block-iterative methods, every iteration of the algorithm is subdivided into many subsequent sub-iterations, each using a different subset of the projection data. an example of a widely used block-iterative version of mlem is the ordered subsets expectation maximization algorithm (osem). the reconstruction speedup of a full iteration osem over a single iteration mlem is approximately equal to the number of subsets. | wikipedia |

if m and n are not assumed to be simply connected, then an h -cobordism need not be a cylinder. the s -cobordism theorem, due independently to mazur, stallings, and barden, explains the general situation: an h -cobordism is a cylinder if and only if the whitehead torsion of the inclusion m ⊂ w vanishes. this generalizes the h -cobordism theorem because the simple connectedness hypotheses imply that the relevant whitehead group is trivial. in fact the s -cobordism theorem implies that there is a bijective correspondence between isomorphism classes of h -cobordisms and elements of the whitehead group. | wikipedia |

lutetium tantalate is a chemical compound of lutetium, tantalum and oxygen with the formula lutao4. with a density of 9.81 g/cm3, this mixed oxide compound is the densest known white stable material. (although thorium dioxide tho2 is also white and has a higher density of 10 g/cm3, it is radioactively unstable; while not radioactive enough to make it unstable as a material, even its low rate of decay is still too much for certain uses such as phosphors for detecting ionising radiation.) the white color and high density of lutao4 make it ideal for phosphor applications, though the high cost of lutetium is a hindrance. | wikipedia |

endosymbiotic gene transfer is how we know about the lost chloroplasts in many chromalveolate lineages. even if a chloroplast is eventually lost, the genes it donated to the former host's nucleus persist, providing evidence for the lost chloroplast's existence. for example, while diatoms (a heterokontophyte) now have a red algal derived chloroplast, the presence of many green algal genes in the diatom nucleus provide evidence that the diatom ancestor (probably the ancestor of all chromalveolates too) had a green algal derived chloroplast at some point, which was subsequently replaced by the red chloroplast. | wikipedia |
