Redescription of the Triassic cynodont Cistecynodon parvus and reassessment of its phylogeny
The Anatomical Record, EarlyView.Abstract Cynodontia is an important subclade of Therapsida that first occurred in the late Permian. It includes extinct subclades which are the non‐mammaliaform cynodonts and Mammaliaformes, with the latter ultimately giving rise to crown mammals. The systematics of non‐mammaliaform cynodonts has been extensively studied and is relatively well‐resolved,

Nonlinear dynamics of turbulent waves in fluids and plasmas [PDF]
Nonlinear Processes in Geophysics, 2005 In a model drift wave system that is interesting both in fluids and plasmas, we find that an embedded moving saddle point plays an important role at the onset of turbulence.

Evolutionary morphology of the haplorhine hamate
The 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.

Finite Larmor radius influence on MHD solitary waves [PDF]
Nonlinear Processes in Geophysics, 2009 MHD solitons are studied in a model where the usual Hall-MHD model is extended to include the finite Larmor radius (FLR) corrections to the pressure tensor. The resulting 4-dimensional set of differential equations is treated numerically.

Anatomical Sciences Education, EarlyView.Abstract Providing students with a way to honor human body donors during or after an anatomy course has been shown to help provide a sense of closure and comfort to students and, when present, donor families. Gestures of gratitude for donors can also emphasize humanistic values of respect, empathy, and professionalism.

Dynamical Behaviour of a Time Delay Model of the ERK and STAT5 Interaction [PDF]
Bioautomation, 2007 In this paper we have done sensitive analysis of a time delay model which describes the ERK and STAT5 interaction. The results show that the type of the equilibrium point of the model can be a compound saddle-focus or a compound saddle-knot.

Arthroscopy Techniques, EarlyView.Abstract This technical note describes a practical, anatomy‐based medial patellofemoral ligament reconstruction technique emphasizing individualized, dynamic graft tensioning and independent adjustment of patellar graft arms. By prioritizing femoral fixation first, guided by precise, dynamic anatomical landmarks and arthroscopic verification, the graft

Natural preconditioners for saddle point systems [PDF]
, 2013 The solution of quadratic or locally quadratic extremum problems subject to linear(ized) constraints gives rise to linear systems in saddle point form.

Next Generation Hosts for Protein Recognition, Assembly and More
Chemistry – A European Journal, EarlyView.The original design of synthetic receptors for proteins was based on macrocycles with a hydrophobic core and a polar/charged periphery. This design, geared towards protein recognition, facilitates receptor self‐assembly. Macrocycle oligomerization, in turn, contributes to protein assembly as evidenced in many cocrystal structures.

Chemistry – A European Journal, EarlyView.We present a machine‐learning framework that predicts the electron localization function (ELF) of dense hydrogen directly from atomic geometry, bypassing explicit electronic‐structure calculations. Trained on ab initio data for fluid hydrogen across multiple pressures, the model achieves high accuracy and reveals pressure‐dependent nonlocal ...
