Given a passage with a question and an answer to that question, classify if the answer actually answers the question into 'yes' or 'no'. Output 'yes' if the answer answers the question and output 'no' if the answer does not answer the question.

Question: Question: Do integrin-associated complexes form hierarchically with variable stoichiometry in nascent adhesions?
Answer: These observations suggest a working model for NA assembly whereby transient -actinin-integrin complexes help nucleate NAs within the lamellipodium. Subsequently, integrin complexes containing kindlin, but not talin, emerge. Once NAs have formed, myosin II activity promotes talin association with the integrin-kindlin complex in a stoichiometry consistent with each talin molecule linking two integrin-kindlin complexes.

Answer: yes

Question: 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.

Answer: yes

Question: Question: Does increased pulsatility of the intracranial blood flow spectral waveform on transcranial Doppler point to peripheral arterial disease in stroke patients?
Answer: Our findings indicate that PAD cannot be inferred from intracranial flow parameters predictive of arterial disease and risk factors such as hypertension among patients with acute cerebral ischemia.

Answer:
no
