Within the Diptera, two different selfish genetic elements are known to cause the production of female-biased sex ratios: maternally inherited bacteria that kill male zygotes (male-killers), and X chromosomes causing the degeneration of Y-bearing sperm in males (meiotic drive). We here develop ...

On the other hand, we have loads of other numbers whose decimal forms are non-repeating, non-terminating decimals; these number are non-rational (that is, they cannot be written as ratios of two integers); this is why they are called the "irrationals". Examples of irrationals in decimal...

Furthermore, ratios of words per sentence or sentences per paragraph can be interpreted as a proxy for syntactic complexity (Crowhurst, 1983). In addition, many traditional readability metrics consider word and sentence length (Pitler & Nenkova, 2008). Other length features typically used in AES ...
Five examples of simulations using 2/1 (Au/surfactant) molar ratios are shown in Fig. 2. Figure 2 Snapshots taken at 1125, 2250, 3375 and 4500 ps. (a) O-type/Au. (b) S-short/Au. (c) S-long/Au. (d) N-type/Au. (e) C-type/Au. Gold beads were represented in CPK of ...
Table 5 indicates the demand to capacity ratios (D/C) of the most critical column next to the lost column before and after the destructive event. By evaluating the D/C ratios, it is determined that increase in D/C ratio in 3-story buildings is greater than those of other taller building...
The efficacy of rhythmic acoustic stimulation (RAS) to improve gait and balance in healthy elderly individuals is controversial. Our aim was to investigate, through 3D gait analysis, the effect of different types of RAS (fixed frequency and based on subject-specific cadence), using conventional gai...
(抽象的) thought and quantitative reasoning. For example, geometry and music have much in common, such as the use of symmetry (对称). Arithmetic may lend itself particularly well to being taught through music because central concepts, such as fractions and ratios (比例), are also important to...
