The phrase "are practically demonstrated" is correct and usable in written English.
It can be used when discussing evidence or examples that show something to be true or valid in a practical sense.
Example: "The theories we discussed in class are practically demonstrated through various real-world applications."
Alternatives: "are effectively shown" or "are clearly illustrated".
It is practically demonstrated that wavelength shift, broadening of a full width at half maximum (FWHM) and reduced transmittance at central wavelength can be determined by comparing the performance of the designed optical filters.
But yes, a curve ball really curves, as was practically demonstrated by one Freddy Goldsmith in an experiment conducted in New Haven as long ago as 1870; but a curve ball that seems to break more than 14 inches never actually deviates from a straight line by more than 3 1/2 inches.
To validate the feasibility of the proposed security solution, it is implemented for an existing wireless sensor network system and its functionality is practically demonstrated by successfully detecting the presence of any suspicious sensor node and anomalous activity in the base station with high accuracy and minimal performance overhead.
The potential of the proposed methodological approach, still to be practically demonstrated, should be contrasted with the approaches presently used.
Some works in the area [5 7] have considered a theoretical virus which has not been practically demonstrated.
Moreover, the extraction of a scattered object field is practically demonstrated to result in optical sectioning.
At the Quest for Orthologs meeting in 2013, some of these benefits were practically demonstrated through the RDF versions of Roundup, OGO and MBGD (see http://questfororthologs.org/orthology_databases for Web links).
Overall, the study provides atomic-level insight into a system, where both the tetarto-hydrate and anhydrate are practically relevant and demonstrates that a proper set of complementary analytical techniques is required to achieve a high level of understanding of hydrate systems.
Some of these results are practically interesting, because they demonstrate that in certain cases, when putting restrictions on the second-stage-sample sizes, naive strategies can control the type 1 error rate.
To assess whether these biases resulted from biased PCR amplification during the sequencing reaction, we repeated these analyses using only unique sequence tags, but the obtained results were practically indistinguishable, demonstrating that the effect cannot be attributed to biased PCR amplification (Supporting Information S1).
