Evolutionary morphology of the haplorhine hamate

open access: yesThe Anatomical Record, EarlyView.
Abstract Primates adopt a variety of hand postures during an impressive diversity of locomotor and manipulative behaviors. Morphological research has found that elements of the hand skeleton, such as the hamate, hold key information for inferring hand use and locomotor kinematics in extinct species.

The Fractional Ornstein-Uhlenbeck Process: Term Structure Theory and Application [PDF]

open access: yes
The paper revisits dynamic term structure models (DTSMs) and proposes a new way in dealing with the limitation of the classical affine models. In particular, this paper expands the flexibility of the DTSMs by applying a fractional Brownian motion as the ...

Humans and platyrrhines share a pattern of articular variance

open access: yesThe Anatomical Record, EarlyView.
Abstract Previous work has identified a pattern of articular shape variation in modern human limb joints, in which convex joint surfaces exhibit constrained variance relative to their more variable concave conarticulars. This pattern is notable given that joint morphogenesis is influenced by local biomechanical environments, which vary substantially ...

Redescription of †Eobrasilia coutoi (Metatheria: Polydolopimorphia), a unique sclerocarpophagous metatherian from the Palaeogene of South America: Systematic affinities, and paleoecological and evolutionary implications

open access: yesThe Anatomical Record, EarlyView.
Abstract The ‘Palaeogene strata’ of the Itaboraí Basin (upper Paleocene‐lower Eocene), Southeastern Brazil, has preserved 29 genera and almost 50 species of metatherians (about 65% of its mammalian diversity). Among them, Eobrasilia coutoi Simpson, 1947 is the most enigmatic due to its quite fragmentary nature.

Hurst exponents, Markov processes, and fractional Brownian motion [PDF]

open access: yes
There is much confusion in the literature over Hurst exponents. Recently, we took a step in the direction of eliminating some of the confusion. One purpose of this paper is to illustrate the difference between fBm on the one hand and Gaussian Markov ...

Diffusion Coefficient and Viscosity of Methyl Viologen Electrolyte Estimation Based on a Kinetic Monte Carlo Computational Approach Coupled with the Mean Square Displacement Method

open access: yesBatteries &Supercaps, Volume 8, Issue 3, March 2025.
A novel and comprehensive 3D‐resolved kinetic Monte Carlo model coupled with mean square displacement analysis is introduced. This computational approach allows to explore, for the first time, the concentration and the state of charge effects on ionic diffusion coefficient and viscosity in methyl viologen‐based electrolytes used in organic redox flow ...

Integrated biorefinery for cellulosic ethanol and spherical nanolignin production from coconut waste

open access: yesBiofuels, Bioproducts and Biorefining, EarlyView.
Abstract Green coconut waste was subjected to different fractionation methods to obtain integrated lignin nanoparticles and cellulosic ethanol. Pretreatment with gradual addition of dilute sulfuric acid provided a higher structural hemicellulose precursor yield (68.2%).

Schwebende Tröpfchen: Experimentelle Wissenschaftsgeschichte und ein neuer Blick auf Textquellen**

open access: yesBerichte zur Wissenschaftsgeschichte, EarlyView.
Experimental history of science broadens the range of sources available to historians. Through the practical re‐enactment of historical experiments, observations and experiential knowledge can be gained that provide insight into scientific practice. Using research on Brownian motion conducted with the famous oil‐drop apparatus as a case study, this ...
