Objectives: To assess whether the observed vs. expected lung-to-head ratio (o/e LHR) corrects for the dependence of the LHR on gestational age. Study design: Published data on right lung area (LA) and LHR were used to plot the 50th percentile and different fixed values of the o/e LHR...
where O is the observed frequency in each category, E is the expected frequency in the corresponding category, and [chi square] is the chi-square value. Study of glove perforation during hip replacement arthroplasty: its frequency, location, and timing More results ► Thesaurus browser ? ▲ ...
During social interactions, we continuously integrate current and previous information over varying timescales to infer other people's action intentions. Motor cognition theories argue for a hierarchical organization of goal-directed actions based on tem
Larger velocity amplitude with the value of 0.15 m/s (the white line in Fig. 2a) is observed in the upper 460 m layer before April 19. However, the isoline of 0.15 m/s gradually rises to 150 m on May 19. The discrepancy of the upper and deep layers between March 20...

Thanks. I haven’t used R yet, but should probably start. I used to use SPlus, which I understand is the same or very similar, so I’m sure it wouldn’t be much of a stretch. But I find that most of my clients use either SPSS or SAS. I suspect R is going to infiltrate the...
Although the significance of these differences was not tested, the B1 level discrepancy (1.71 clauses per T-unit for Chinese vs. 2.59 clauses per T-unit for Spanish) was significant enough to warrant attention. In contrast, Khushik and Huhta (2020) ascertained significant differences in SC ...
TRVs for Ingestion Exposures for the Class Mammalia NOAELs andLOAELsfrom a variety of studies are presented inTable 27.2. Two chronic studies [33,34] and two reproductive/developmental studies [41,43] were identified as relevant to TRV derivation. ...
Figure 4 plots the transmission likelihood \(\hat{\beta }T\) against the saturation for full-class vs. half-class and for not vaccinated vs. teacher vaccinated scenarios. Saturation parameters appeared to grow with transmission likelihood and, at the highest transmission likelihood, converged around...
In the case of PbTiO3 nanodots, however, we obtained a striking correlation that for the thickness less than a certain critical value, dc (~35 nm), the domain width even increases with decreasing thickness of the nanodot, which surprisingly indicates a negative value in the LLK scaling-...
