摘要:
The present disclosure relates to a method for sampling rock mass, especially jointed rock mass. The present disclosure provides a simple and convenient method for sampling jointed rock mass to prevent the rock sample from being disturbed and damaged during sampling and accordingly resulting in opening of the weak structural planes, to therefore obtain rock specimen correctly reflecting the basic physical and mechanical characteristics of rock mass comprising integral fissure network. The method for sampling jointed rock mass of the present disclosure comprises the following steps: Step a: Siting; Step b: Drilling; Step c: Protecting; and Step d: Sampling. The method is suitable for determining the basic mechanical properties of the rock mass and for assessing the stability of caverns in jointed rock mass.

Provided are a method, system, and computer-readable medium for determining whether a copy number variation exists in a sample genome. The method includes sequencing a sample genome to obtain a sequencing result formed by multiple reads; comparing the sequencing result with a reference genome sequence to determine the distribution of the reads on the reference genome sequence; determining, based on the distribution of the reads on the reference genome sequence, multiple breakpoints on the reference genome sequence, wherein the number of the reads on either side of each breakpoint are significantly different; determining, based on the plurality of breakpoints, a detection window on the reference genome; determining, based on the reads falling in the detection window, a parameter; and determining, based on the difference between the first parameter and a preset threshold, whether a copy number variation exists in the sample genome against the detection window.

The present disclosure relates to freeze-tolerant transgenic Eucalyptus, including methodology for making and products produced there from. Following exposure to cold temperature, and compared to a control plant, the freeze-tolerant Eucalyptus displays a freeze-tolerant phenotype characterized by at least one of increased height, less leaf damage, less dieback of main stem, less crown defoliation, and/or improved tree stem form.

The present disclosure relates to a new, distinct and stable variety of freeze-tolerant Eucalyptus hybrid variety. Following exposure to cold temperature, and compared to its parent plant, the freeze-tolerant hybrid variety displays increased height, less leaf damage, less dieback of main stem, less crown defoliation, and improved tree stem form.
摘要:
A method of manufacturing components includes providing a substrate (110, 531, 631, 700) having a first coefficient of thermal expansion (CTE), having a first surface (111), and supporting a first plurality of interconnects located over the first surface in a first predetermined pattern. The method also includes providing another substrate (190) having a second CTE, having a second surface (195), and supporting a second plurality of interconnects located over the second surface in a second predetermined pattern. The method further includes assembling together the two substrates at a first temperature outside of a temperature range of approximately 25 to 30° C.
