We found, however, the gravity p-median model to be of limited use for the problem of locating facilities as it either gives solutions similar to the p-median model, or it gives unstable solutions due to a non-concave objective function....
location be investigated by the p-median or the gravity p-median model? Turning back to the arguments for using the gravity p-median model, we note that the first argument does not apply for this setting. The error in location is inconsequential and may, at the most, be 175 meters ...
We favour the gravity -median model, but we note that in an applied setting, Drezner and Drezner's arguments are incomplete. In this communication, we point at the existence of a fourth compelling argument for the gravity -median model. 展开 ...
These multiepoch observations of WR140 constitute the first direct detection of dust structures undergoing acceleration in the circumstellar radiation field: more commonly proper motions recorded are under the influence of gravity. Acceleration due to interactions other than gravity, however, are rarely ...

Note though that the model does not necessarily assume that tilt tuning is anchored to gravity, as another reference vertical could be used as an input. This model could fit conjunctive cells well (Fig. 4d; n = 16 ADN, 4 RSC, 33 CIN; median ρ = 0.88, [0.86–0.91] CI), ...
Skeletal muscle undergoes atrophy and loss of force during long space missions, when astronauts are persistently exposed to altered gravity and increased ionizing radiation. We previously carried out mass spectrometry-based proteomics from skeletal muscl
This could be due to participants leaning slightly forward at T1, positioned with their centre of gravity towards their toes, causing Madymo dummies to also lean forward. This posture creates a mechanical advantage for maintaining the vertical angle due to the distribution of the mass of the foot...
from chronic hyperglycemia as functional cell mass is gradually lost over time44, elevated BG levels due to poor graft function may induce sustained increases in islet OCR, in turn worsening islet function and survival and may thus accelerate graft attrition in the mouse model (Supplementary Fig. ...
