Introduction: Previous studies have shown that vertebral bone metastases not seen on planar bone scans may be present on F-18 fluoride positron emission tomography (PET) scan or single photon emission computed tomography (SPECT). The purpose of this study was to measure the accuracy, clinical ...

16.The cost of the materials used was very high. 17.Making mistakes can sometimes cost us the opportunity of a lifetime. 18.Producing this product cost more than expected. 19.The cost of hiring a new employee is too high. 20.We had to pay an expensive cost for their mistakes....
calculating key indices such as the Cost of Living Index and Local Purchasing Power offering a platform for conducting other systematic economic research on an extensive global dataset If you find Numbeo useful, you can contribute bysharing local price informationto further help improve the accuracy ...
Record efficiencies are currently achieved through a combination of spin-coating highly concentrated precursor solutions with an anti-solvent drip approach13,17. But one downside of most laboratory-based spin-coating of high concentration solutions is precursor waste generated during processing, which ...
Cropland is a main source of global nitrogen pollution1,2. Mitigating nitrogen pollution from global croplands is a grand challenge because of the nature of non-point-source pollution from millions of farms and the constraints to implementing pollution-r

The choice of these inputs, especially for nonfood, is arbitrary. The imputation of joint costs and scale effects is an unsolved problem. The more sophisticated method based on food shares tends to overestimate the cost ratios, because it does not account for fixed costs. The "adult goods" ...
People usually move at a self-selected pace in everyday life. Yet, the principles underlying the formation of human movement vigour remain unclear, particularly in view of intriguing inter-individual variability. It has been hypothesized that how the bra
The designed APM consists of M×N amplifying unit cells, which can dynamically generate the required high-power beams by controlling the phase distribution using the field-programmable gate array (FPGA). As the fundamental part of APM, the amplifying unit cell consists of an amplifier circuit, a...
