四、反函數(inverse function) 若有一函數 f 代表 X→Y,則其反函數 f⁻¹ 就是 Y→X,可以有反函數的函數稱為「可逆函數(invertible function)」,所有可逆函數必為雙射函數。 在下圖中,f(x) 與 f⁻¹(x) 互為反函數關係、g(x) 與 g⁻¹(x) 亦互為
However, there may prove to be a relation between a bimodal fibril diameter distribution at maturity and the maintenance over long periods of time of either high stress in stretched tissues or low stress in compressed tissues. It has also been noted that the width of the collage...

In this paper, an intrinsic relation was developed for Hyades stars between a function of the right ascensions α and declination δ with the angular distance λ from the vertex. The precision criteria of this relation are very satisfactory and a correlation coefficient of value ≈ 1 was found ...
If we assume a function rectangle to be at hand that yields for a given non-empty relation R:X↔X a non-empty rectangle S:X↔X such that S⊆R holds, then a combination of the right-hand side of the implication (2) with the equations ...
where w 1 and b 1 are the parameter matrix and bias vector that are learned, and tanh denotes the hyperbolic tangent activation function. to generate the character-level representation r w of this word w , max-pooling operations are applied to all kernel outputs o 1 , o 2 ,…, o n ...
Relation, in logic, a set of ordered pairs, triples, quadruples, and so on. A set of ordered pairs is called a two-place (or dyadic) relation; a set of ordered triples is a three-place (or triadic) relation; and so on. In general, a relation is any set o
Our goal was to assess the associations of arsenic exposure and arsenic metabolism with HDP and blood pressure changes in pregnant women through a prospective birth cohort study. A total of 1038 women who were pregnant (52 HDP, 986 non-HDP participants) were included. Arsenic species of spot ...
In advanced CKD and ESRD, left ventricular structure and function anomalies (left ventricular hypertrophy, low ejection fraction and so on) investigated by a large variety of imaging methods, proved to be associated with high cardiovascular and all-cause mortality risk5,6,7. Most of the available...
Eugene Stanley1,4 Identifying influential nodes in dynamical processes is crucial in understanding network structure and function. Degree, H-index and coreness are widely used metrics, but previously treated as unrelated. Here we show their relation by constructing an operator H, in terms of which...
