We used single-use surgical masks (BYD Precision Manufacture) with 3 layers (ie, an outer layer of polypropylene spunbonded nonwoven fabric, a middle layer of polypropylene melt-blown nonwoven fabric, and an inner layer of polypropylene spunbonded nonwoven fabric), ear loops consisting of a ...
Melt-textured YBCO monoliths with different shape and a maximum size of 60 mm can be reproducible prepared in a batch process. Seeding by self-made SmBa_2Cu_3O_x leads to single domain material. Zero field cooled levitation forces at 77 K higher than 80 N were achieved. In single domain...
In a first step, the dataset a is reshaped into long format long ID variable value 1: a x1i 1 2: b x1i 1 3: a x2i 2 4: b x2i 4 5: a x3i 4 6: b x3i 1 Now, variable contains the column names as data items which simplifies subsequent steps. Note that melt(...
The suggestions to usemeltandcast(nowdcastand family) from the "reshape" (now "reshape2") package won't get you to the form you are looking for with your data. In particular,you'll need to do some additional processingif your end goal is the "semi-long" format you describe. ...
