The Anatomical Record, EarlyView.Abstract The oval window (OW) is an opening connecting the inner and middle ear. Its area has been shown to consistently scale with body mass (BM) in primates, and has been used alongside semi‐circular canal (SCC) size to differentiate Homo sapiens and fossil hominins, including Paranthropus robustus.

Whole‐bone shape of hominoid manual proximal phalanges
The Anatomical Record, EarlyView.Abstract Functional morphologists have long noted that skeletal adaptations in primate phalanges reflect locomotor behavior. While most studies have successfully used two‐dimensional measurements to quantify general features of phalanx shape, a whole‐bone three‐dimensional analysis may better capture more subtle aspects of phalanx morphology that have ...

Numerical competence in a chimpanzee (Pan troglodytes).
Journal of Comparative Psychology, 1989 A chimpanzee (Pan troglodytes), trained to count foods and objects by using Arabic numbers, demonstrated the ability to sum arrays of 0-4 food items placed in 2 of 3 possible sites. To address representational use of numbers, we next baited sites with Arabic numbers as stimuli.

Bayesian Computation and Model Selection in Population Genetics [PDF]
arXiv, 2009 Until recently, the use of Bayesian inference in population genetics was limited to a few cases because for many realistic population genetic models the likelihood function cannot be calculated analytically . The situation changed with the advent of likelihood-free inference algorithms, often subsumed under the term Approximate Bayesian Computation ...

Nanotechnology in brain cancer treatment: The role of gold nanoparticles as therapeutic enhancers
Ibrain, EarlyView.This review highlights the potential of gold nanoparticles (AuNPs) in overcoming the blood‐brain barrier (BBB) to improve brain tumor treatment. By enabling targeted drug delivery and enhancing therapies like radiotherapy, phototherapy, and chemotherapy, AuNPs offer a promising approach for safer, more effective treatments of glioblastoma and other ...

JPGN Reports, EarlyView.Abstract This is a comprehensive review of pediatric foreign body (FB) ingestions, emphasizing the global burden, epidemiology, and management strategies. Predominantly occurring in children under 6, with a peak between 6 months and 3 years, these incidents pose significant health risks with substantial regional variations in ingested objects—ranging ...

Aging and sex affect soluble alpha klotho levels in bonobos and chimpanzees
Frontiers in Zoology, 2018 Background Throughout life, physiological homeostasis is challenged and the capacity to cope with such challenges declines with increasing age. In many species, sex differences exist in life expectancy.

Markovian Memory Embedded in Two-State Natural Processes [PDF]
arXiv, 2008 Markovian memory embedded in a binary system is shaping its evolution on the basis of its current state and introduces either clustering or dispersion of binary states. The consequence is directly observed in the lengthening or shortening of the runs of the same binary state and also in the way the proportion of a state within a sequence of state ...
