A quantitative approach to painting styles

This research extends a method previously applied to music and philosophy (Vilson Vieira et al., 2012), representing the evolution of art as a time-series where relations like dialectics are measured quantitatively. For that, a corpus of paintings of 12 well-known artists from baroque and modern art is analyzed. A set of 99 features is extracted and the features which most contributed to the classification of painters are selected. The projection space obtained provides the basis to the analysis of measurements. These quantitative measures underlie revealing observations about the evolution of painting styles, specially when compared with other humanity fields already analyzed: while music evolved along a master-apprentice tradition (high dialectics) and philosophy by opposition, painting presents another pattern: constant increasing skewness, low opposition between members of the same movement and opposition peaks in the transition between movements. Differences between baroque and modern movements are also observed in the projected "painting space": while baroque paintings are presented as an overlapped cluster, the modern paintings present minor overlapping and are disposed more widely in the projection than the baroque counterparts. This finding suggests that baroque painters shared aesthetics while modern painters tend to "break rules" and develop their own style.

Chronic neck pain in young adults: perspectives on anatomic differences.

Neck pain (NP) is a common musculoskeletal disorder, but little is known about the associated risk factors. We compared anatomic differences in the neck and trunk area of young adult patients with chronic NP and control subjects without NP to identify risk factors and predictors. This is an age-, sex-, and body mass index-matched retrospective case-control study of a consecutive sample. Patients with axial NP for longer than 6 months (23 males and 25 females) and pain-free volunteers (23 males and 25 females) were included. Outcome measures were linear and angular dimensions of the cervicothoracic junction. Midsagittal magnetic resonance imaging scans of the cervicothoracic spine were obtained. Four linear and four angular parameters were identified and measured. These parameters included depth of the T1-manubrium arch (T1AD), depth of the thoracic cage (TXD), tangential height of T1 (T1H1), relative height of T1 (T1H2), T1 slope (T1S), thoracic inlet inclination (TiI), T1-manubrium arch inclination (T1AI), and the angular difference between TiI and T1AI (TiI-T1AI). The measurements were taken by two neurosurgeons. Depth of the T1-manubrium arch and TiI were identified as predictors for NP in the binary logistic regression analysis. Each millimeter increase in T1AD lessened the probability of NP with an adjusted odds ratio (OR) of 0.823 (95% confidence interval [CI], 0.701-0.966) in females and 0.809 (95% CI, 0.681-0.959) in males. Each degree increase in TiI was associated with the probability of NP with an adjusted OR of 1.247 (95% CI, 1.060-1.466) in males. Measurement of cervicothoracic junctional structures is a reliable and feasible method of estimating potential predictor of chronic NP in young adults. Forward inclination of the thoracic inlet in males and a shallow thoracic cage in females were identified as important predictors. Copyright © 2014 Elsevier Inc. All rights reserved.
