In this task, you're given a paragraph and title from the research paper. Your task is to classify whether the given title is suitable or not for the research paper based on the given paragraph. Return "True" if title is proper according to paragraph else "False".

Paragraph: The major biochemical and thermodynamic features of nucelocapsid protein of SARS coronavirus (SARS _ NP) were characterized by use of non-denatured gel electrophoresis, size-exclusion chromatographic and surface plasmon resonance (SPR) techniques. The results showed that SARS _ NP existed in vitro as oligomer, more probably dimer, as the basic functional unit. This protein shows its maximum conformational stability near pH 9.0, and it seems that its oligomer dissociation and protein unfolding occur simultaneously. Thermal-induced unfolding for SARS _ NP was totally irreversible. Both the thermal and chemical denaturant-induced denaturation analyses showed that oligomeric SARS _ NP unfolds and refolds through a two-state model, and the electrostatic interactions among the charge groups of SARS _ NP made a significant contribution to its conformational stability. D Abbreviations: SARS _ CoV, severe acute respiratory syndrome coronavirus; SARS _ NP, nucleocapsid protein of SARS; SPR, surface plasmon resonance; GuHCl, guanidine hydrochloride; CD, circular dichroism; T m and C m , transition midpoints of thermal and chemical denaturations; IPTG, isopropyl-h-d-thiogalasctopyranoside; N and U, native and unfolded states.

Paragraph: The dynamics of coronavirus disease 2019 (COVID-19) transmissibility after symptom onset remains unknown. We conducted a prospective case-ascertained study on laboratory-confirmed COVID-19 cases and their contacts. Secondary clinical attack rate (considering symptomatic cases only) was analyzed for different exposure windows after symptom onset of index cases and for different exposure settings. Thirty-two confirmed patients were enrolled and 12 paired data (index-secondary cases) were identified among the 1,043 contacts. The secondary clinical attack rate was 0.9% (95% CI 0.5-1.7%). The attack rate was higher among those whose exposure to index cases started within five days of symptom onset (2.4%, 95% CI 1.1-4.5%) than those who were exposed later (zero case from 605 close contacts, 95% CI 0-0.61%). The attack rate was also higher among household contacts (13.6%, 95% CI 4.7-29.5%) and nonhousehold family contacts (8.5%, 95% CI 2.4-20.3%) than that in healthcare or other settings. The higher secondary clinical attack rate for contacts near symptom onset remained when the analysis was restricted to household and family contacts. There was a trend of increasing attack rate with the age of contacts (p for trend < 0.001). High transmissibility of COVID-19 near symptom onset suggests that finding and isolating symptomatic patients alone may not suffice to contain the epidemic, and more generalized social distancing measures are required. Rapid reduction of transmissibility over time implies that prolonged hospitalization of mild cases might not be necessary in large epidemics.

Paragraph: medRxiv preprint Effect of pre-existing immunity on seroconversion to recent strains Pre-existing, homologous titer to circulating strains is a well-described predictor of risk of seroconversion (14), which is confirmed in our study (Table 1 and tables S5 and S6). However, we hypothesized that including metrics of antibody profiles that integrate previous exposure history would further improve predictions of the risk of seroconversion. Therefore, we examined the association between the risk of seroconversion with age at baseline sampling, pre-existing, homologous titer to outcome strains (the ith strain), titer to the i-1th strain, and summary metrics .
