The pantograph-catenary system is a key part of Cages power supply for electric locomotive, and its operating status determines the current receiving quality of electric locomotive, as well as safety and efficiency of trains.In order to solve the problems of traditional method for inspection of pantograph-catenary status, such as low efficiency and
While the reductionist approach has been fruitful in understanding the molecular basis of muscle function, intact excitable muscle preparations are still important as experimental model systems.We present here methods that are useful for preparing cardiac papillary muscle and cardiac slices, which represent macroscopic experimental model systems wi
Proof assistants and programming languages based on type theories usually come in two flavours: one is based on the standard natural deduction presentation of NATIVE PRO type theory and involves eliminators, while the other provides a syntax in equational style.We show here that the equational approach corresponds to the use of a focused presentati
Abstract Long-term mining planning is a complex process which involves a large number of variables and uncertainties.Traditional discount cash flow (DCF) is usually used in the evaluation of mining projects.DCF includes net Giftware present value (NPV), internal rate of return (IRR), and profitability index (PI).A sensitivity analysis is usually ca
Aberrant Cages activation of the RET proto-oncogene is implicated in a plethora of cancers.RET gain-of-function point mutations are driver events in multiple endocrine neoplasia 2 (MEN2) syndrome and in sporadic medullary thyroid cancer, while RET rearrangements are driver events in several non-medullary thyroid cancers.Drugs able to inhibit RET ha
