A miner assembles a block from a list of unprocessed transactions plus other information, including a 4-byte (32-bit) variable field called a "nonce," then runs the result through an SHA-256 hashing algorithm.
For example, manufacturers looking to comply with FDLA date-stamping requirements should look for a labeling solution that easily generates QR codes and features variable field styling, rich text fields, "What You See Is What You Get" (WYSIWYG) label design, smart label templates and Visual Basic Scripting (VBScript) or other variable formulaic options.
The reason for this phenomenon may be that the new variable information obtained by the gradient information transformation in the gradient information assimilation method contains a certain degree of gradient information of the horizontal direction physical variable field, but the concrete reason needs to be further studied in the following work.

LARS produces continuous x-ray movies of complex objects with a variable field of view as great as 200 mm, durations that range from microseconds to seconds and a spatial resolution of 300 microns.
Features of this new technology include variable field operation, higher intrinsic magnetic field homogeneity, larger fields of view (FOV) elliptical in shape to better fit the subject and automatic field ramping.
The content of variable field data can take the form of patient ID numbers, QR codes, and other data formats that create unique attributes for each label in a study.
With parasitic flies gorging on her guts and the end approaching, a variable field cricket may have time to do only one more thing: Find a mate.
Magnetic nanoparticles provide local and independent magnetic behavior in a two dimensional space under a variable field.The advantage of these spaces over multilayered ones is the single size of nanoparticles and removal of exchange interaction between them.
where f is the damping force [N]; x and y are the primary, respectively the secondary displacement variables [m]; z is the internal history dependency variable of the (MRD) [m]; [k.sub.0], [k.sub.1] are the non linear internal rigidity of the (MRD), [N/m] depending of the current intensity i [A]; [c.sub.0] and [c.sub.1] are the internal viscous damping parameters of the (MRD) [Ns/m]; [alpha] is the internal parameter what have non linear evolution and depend on the magnetic variable field (electrical intensity); parameter [beta] characterize the gain of increasing of the damping force versus velocity; [x.sub.0] is the perturbation displacement [m]; [delta] is the hysteresis parameter.
