Accurate Extra-Galactic Distances and Dark Energy: Anchoring the Distance Scale with Rotational Parallaxes [PDF]
, 2006 We investigate how the uncertainty on the Hubble constant (H_0) affects the uncertainty in the Equation of State (EOS) of Dark Energy and the total density of the Universe (Omega_tot). We use the approximate relations between the cosmological parameters [

Prediction of potential and attainable yield of wheat : A case study on yield gap
MAUSAM, 2002 This study reports the role of field experimentation and system simulation in better quantifying the productivity of wheat crop, and examine how knowledge on potential productivity can improve the efficiency of the production system. When knowledge from field experimentation is utilised into crop weather simulation models, gap between actual ...

Quantum metrology with full and fast quantum control [PDF]
, 2017 We establish general limits on how precise a parameter, e.g. frequency or the strength of a magnetic field, can be estimated with the aid of full and fast quantum control.

Maximum Attainable Wheat Yield and Resource‐Use Efficiency in the Southern Great Plains [PDF]
Crop Science, 2015 ABSTRACTMaximum reported grain yields for hard red winter wheat (Triticum aestivum L.) in the southern Great Plains range from 6 to 8 Mg ha–1 and are significantly lower than yields achieved in other regions of the world. The lack of empirical data for wheat under nonlimiting conditions in this region, however, suggests that maximum reported grain ...

Why should space-time variability of rainfall be considered in precision agriculture for soybean in Piracicaba, São Paulo state? [PDF]
Scientia AgricolaBrazil ranks among the world's largest soybean producers; however, significant gaps in crop yield still exist, primarily linked to weather conditions. This study quantifies rainfall spatial variability using two dense networks of rain gauges and examines

Predicting spring wheat yields based on water use-yield production function in a semi-arid climate
Spanish Journal of Agricultural Research, 2019 Grain yield of spring wheat (Triticum aestivum L.) fluctuates greatly in Western Loess Plateau of China due to limited and highly variable precipitation.

Ultra-high-energy cosmic ray acceleration by relativistic blast waves [PDF]
, 1999 We consider the acceleration of charged particles at the ultra-relativistic shocks, with Lorentz factors \Gamma_s >> 1 relative to the upstream medium, arising in relativistic fireball models of gamma-ray bursts (GRBs).
