Revisiting paravertebral muscles in European rabbits (Oryctolagus cuniculus) and European brown hares (Lepus europaeus) (Leporidae; Lagomorpha)

open access: yesThe Anatomical Record, EarlyView.
Abstract Domesticated European rabbits (Oryctolagus cuniculus) have long been chosen as laboratory model organisms. Despite this, there has been no definitive study of the vertebral musculature of wild rabbits. Relevant descriptions of well‐studied veterinary model mammals (such as dogs) are generally applicable, but not appropriate for a species ...

Redescription of the Triassic cynodont Cistecynodon parvus and reassessment of its phylogeny

open access: yesThe 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,

Belgrade metro studies [PDF]

open access: yesUrbani Izziv, 2009
The subway system is an indispensable part of every modern metropolis. Building a subway is no longer a matter of prestige but a necessity, a consequence of the traffic revolution worldwide.

Impact of increased subway station density on air quality in the Yangtze River Delta

open access: yesEnvironmental Research: Infrastructure and Sustainability, 2023
This study uses empirical methods to explore the relationship between subway system development and air quality in the Yangtze River Delta. We propose a new variable to measure subway development, ‘subway station density value,’ which can more accurately

Drivers of tail evolution in squamates and their implications for the fossorial origin of snakes

open access: yesThe Anatomical Record, EarlyView.
Abstract The axial skeleton serves as the primary structural support in all vertebrates and is subdivided into five distinct regions: cervical, thoracic, lumbar, sacral, and caudal. Relaxation of constraints acting on the terminal end of the axial skeleton has led to remarkable variation in caudal vertebrae number across Squamata.

Study on the critical diameter of the subway tunnel based on the pressure variation

open access: yes, 2014
When the subway train operates at a speed higher than 100 km/h, the corresponding aerodynamic issue becomes severe. To meet the future requirement for the speedup of subway trains, a research on the critical diameters of the subway tunnel for trains ...

Scaling and ecomorphology of lagomorph body shape and appendicular skeleton

open access: yesThe Anatomical Record, EarlyView.
Abstract Body shape is one of the most prominent features of phenotypic variation. Yet, mammalian body shapes are poorly quantified and the underlying components contributing to its diversity and its relationship to other skeletal components are rarely tested.

Optimization of Train Operation in Multiple Interstations with Multi-Population Genetic Algorithm

open access: yesEnergies, 2015
Subway systems consume a large amount of energy each year. How to reduce the energy consumption of subway systems has already become an issue of concern in recent years.

Simulation of Air flow, Smoke Dispersion and Evacuation of the Monument Metro Station based on Subway Climatology

open access: yes, 2014
This research is creating a working laboratory in Newcastle Monument metro station to understand the details of how the over ground climate influences the internal airflow and the impact this has on evacuation strategies.
