always positive always negative zero Concave Mirror: A concave mirror is a converging mirror. Dependent on the location of an object in front of the concave mirror, the image can be real or imaginary. If the object is closer to the mirror than the focal length, the image is ima...

therefore, a larger FOV and vice versa. Additionally, a shorter working distance is needed to obtain the same FOV compared to a longer focal length lens. However, short focal length lenses are associated with higher distortion, which can influence the FOV and cause variations in the angle with...
We report a positive intersexual correlation for T, as a requirement for intralocus sexual conflict. However, high levels of T were associated with increased female and decreased male fitness (fledgling mass), which contrasts our expectations and challenges the hypothesis of intralocus sexual conflict...
length in the F2 hybrid population (R2 = 0.84). However, vertebral length and number were only weakly correlated with each other (r = 0.14,P = 2 × 10−3; Fig.3d), suggesting that variation for these two traits is genetically separable. For all three focal traits, ...
HR-HPV and LR-HPV RNAscope detection was performed on 36 cases in the test group, of which 16 cases were HR-HPV positive and 1 case was LR-HPV positive, with a positive rate of 47.2%. The number of CIN1-CIN3 cases and RNAscope-positive cases in the test group are summarized in ...
For real x with 0 < x < 1, for ex- ample, f is always positive and greater than 1, so we conclude based on the transfer principle that f (0 + dx) > 1 for positive infinitesimal dx. But on similar grounds we can be sure that f (0 + dx) < −1 when dx is negative and ...
