Output: yes


Input: Consider Input: Question: Does a shoe insole delivering subsensory vibratory noise improve balance and gait in healthy elderly people?
Answer: This study provides proof of concept that the application of the principle of stochastic resonance to the foot sole sensory system using a new low-voltage piezoelectric technology can improve measures of balance and gait that are associated with falls. Effective vibratory noise amplitudes range from 70% to 85% of the sensory threshold and can be set once daily.

Output: yes


Input: Consider Input: Question: Does qualitative analysis of high-resolution CT scan in severe asthma?
Answer: HRCT scan abnormalities are common in patients with severe asthma. Nonradiologic assessments fail to reliably predict important bronchial wall changes; therefore, CT scan acquisition may be required in all patients with severe asthma.


Output: yes
