Given a passage classify if the passage has a definite objective/aim/goal or not. Output '1' if the passage has a defininte objective/aim/goal and output '0' if the passage does not have a definite objective/aim/goal.

[EX Q]: Spinally elicited peripheral nerve responses, commonly called neurogenic motor evoked potentials (NMEPs), are widely used to monitor spinal cord motor function during surgery. However, numerous evidence suggests that these responses are primarily sensory rather than motor. The collision technique was utilized to address this issue.', 'Collision studies were performed in 7 patients during surgery. An ascending volley of sensory (AS) and motor activity (AM) was elicited by posterior tibial nerve stimulation at the popliteal fossa. After a short time delay, high cervical spinal stimulation produced a descending volley of sensory (DS) and motor (DM) activity. The AM volley ascended only to the anterior horn cells whereas the AS and DS volleys collided in the spinal cord. The inter-stimulus delays were varied so as to affect the degree of spinal cord collision. The DS and DM activity which remained after collision was recorded from the posterior tibial nerves at the ankle.', 'Inter-stimulus delays of 18 ms or less resulted in no apparent peripheral descending volleys. These findings were consistent for all the patients studied.

[EX Q]: To investigate the differential expressions of nucleolin in invasive cervical squamous cell carcinoma, cervical intraepithelial neoplasms (CIN) and normal cervical epithelial tissues and explore the role of nucleolin in the carcinogenesis and progression of cervical squamous cell carcinoma.', 'Fifty specimens of invasive cervical squamous cell carcinoma, 65 specimens of CIN, and 60 adjacent normal cervical epithelial tissue specimens were examined immunohistochemically for nucleolin expression. The correlation of nucleolin expression levels with histological grades of invasive cervical squamous cell carcinoma and CIN were analyzed.', 'The specimens of invasive cervical squamous cell carcinoma showed a significantly higher positivity rate for nucleolin expression than CIN and normal cervical epithelial tissues, and the rate in CIN tissues was significantly higher than that in normal cervical epithelial tissues (P<0.01). The expression level of nucleolin was significantly higher in invasive cervical squamous cell carcinoma than in CIN and normal cervical epithelia tissues, and higher in CIN than in normal cervical epithelia tissues, whose immunostaining scores were 7.6±0.3, 6.1±0.2, and 3.0±0.2, respectively (P<0.01). The mean nucleolin immunostaining score was significantly higher in poorly and moderately differentiated than in highly differentiated cervical squamous cell carcinoma (7.9 vs 7.1, P<0.01), and higher in high grade CIN than in low grade CIN tissues (6.0 vs 4.0, P<0.01).

[EX Q]: To measure the through-focus curve for eyes implanted with a type 1 Boston keratoprosthesis (KPro) and compare it to that of pseudophakic controls with fixed pupil sizes. The results should assist in evaluating postoperative visual quality after surgery. They should also help to determine the necessary KPro inventories in terms of refractive power steps.', 'Autorefraction and manifest refraction were performed on all eyes. The monocular through-focus acuity curve was plotted in reference to the best-corrected visual acuity by spectacle plane defocus ranging from +5.00 to -5.00\xa0dioptres in 0.50\xa0dioptre increments. These measurements were obtained on KPro-implanted eyes, pseudophakic eyes as controls, and on the same control eyes after fixing the pupil diameter to 3 and 2\xa0mm using black painted iris contact lenses.', 'Ten KPro eyes and five control eyes were included. Good agreement was noted between the subjective refractions and autorefraction in KPro eyes. The average through-focus curve for the control eyes was significantly steeper than that of the KPro curve, but became comparable after fixing the control pupil to 2 and 3\xa0mm.
