These models have more parameter requirements and complexities; however, they better describe mechanisms and have the potential to estimate NPP more accurately when compared with regression-based models. The models based on LUE are called production efficiency models (PEMs), w...
Serial testing, however, unlike initial or 1-time testing, has more stringent requirements and is subject to variability because of technical, procedural, interpretational, and biological factors. The intrinsic variability of MPI becomes important in interpreting serial tests in order to define a true...
SES was mainly measured by two indicators: educational level and subjective social status (SSS). SSS refers to an individual’s subjective perception of his/her social status in society. It has been widely used in health research, and a positive association exists between subjective social status...
42, and is crucial for distribution assessments36,43. Incorporating land cover as a variable into a SDM—the most common practice—generates new, restrictive, requirements for the use of species occurrence data44. Specifically, the land cover data being integrated into SDMs is often...
This approach, although employing low sample size, provides enough species-specific ecophysiology and vulnerability information to prompt immediate reassessment of the conservation status of L. montanezi. Moreo- ver, the SDM predictions can play an important role in support of a habitat conservation ...
The global increase in N deposition is expected to alter soil organic matter and litter decomposition and ultimately, to affect forest ecosystem C storage and nutrient status6,7. Nitrogen deposition has been found to increase, decrease or have no effect on decomposition8, while soil and litter ...
(2) as interconnected machine logic circuits or circuit modules within the computing system. The implementation is a matter of choice dependent on the performance and other requirements of the computing system. Accordingly, the logical operations described herein are referred to variously as states, ...
The main factors that can affect the spread and development of the influenza virus, in addition to strain-specific characteristics, social, and behavioral aspects of the population, the immune status of an individuals, and the level of economy and medical care in the country, are also related ...
However, if they are considered as a craft rather than a ship, they would not have the right to trade on the high seas, and they would have to follow an alternative set of requirements when performing trade on an international scale [11]. Rule 2 of the COLREGS provides overriding ...
In real expressway scenarios, due to the relatively small range of regulating velocity, using only longitudinal control cannot meet the requirements for traffic regulations and policies related to self-driving vehicles on vehicle economy and safety, and it is important to study the lane-changing ...
