A generalized Holling type II model for the interaction between dextral-sinistral snails and Pareas snakes [PDF]

open access: yes, 2019
Producción CientíficaPareatic snakes possess outstanding asymmetry in the mandibular tooth number, which has probably been caused by its evolution to improve the feeding on the predominant dextral snails.

Optimal Axes of Siberian Snakes for Polarized Proton Acceleration

open access: yes, 2004
Accelerating polarized proton beams and storing them for many turns can lead to a loss of polarization when accelerating through energies where a spin rotation frequency is in resonance with orbit oscillation frequencies.

The Road to Redemption: Killing Snakes in Medieval Chinese Buddhism

open access: yesReligions, 2019
In the medieval Chinese context, snakes and tigers were viewed as two dominant, threatening animals in swamps and mountains. The animal-human confrontation increased with the expansion of human communities to the wilderness.

WHAT IS THE LENGTH OF A SNAKE? [PDF]

open access: yes, 2008
The way that herpetologists have traditionally measuredlive snakes is by stretching them on a ruler andrecording the total length (TL). However, due to the thinconstitution of the snake, the large number of intervertebraljoints, and slim muscular mass of

DYNAMIC PARTICLE SYSTEMS FOR OBJECT STRUCTURE EXTRACTION

open access: yesImage Analysis and Stereology, 2011
A new deformable model based on the use of a particle system is introduced. By defining the local behavior of each particle, the system behaves as an active contour model showing a variable topology and regularization properties.

The development of the skull of the Egyptian cobra Naja h. haje (Squamata: Serpentes: Elapidae) [PDF]

open access: yes, 2015
Background: The study of craniofacial development is important in understanding the ontogenetic processes behind morphological diversity. A complete morphological description of the embryonic skull development of the Egyptian cobra, Naja h.

Micro and Nanostructural Diversity of Lizard Osteoderm Capping Tissue in Relation to Mechanical Performance

open access: yesAdvanced Functional Materials, EarlyView.
This study shows that lizard osteoderm capping tissue is a hyper‐mineralized hydroxyapatite layer consistently covering the superficial osteoderm surface in those species studied here, yet it varies greatly in morphology, nanostructure, and mechanical performance across species.

Swift-Hohenberg equation with broken reflection symmetry [PDF]

open access: yes, 2009
The bistable Swift-Hohenberg equation possesses a variety of time-independent spatially localized solutions organized in the so-called snakes-and-ladders structure.

Review of Thin Lithium Metal Battery Anode Fabrication – Microstructure – Electrochemistry Relations

open access: yesAdvanced Materials, EarlyView.
Thin, lightweight lithium‐metal anodes are pivotal for practical high‐energy batteries. This review surveys processing routes that convert diverse Li precursors, e.g., ingots, melts, solutions, and vapor, into Li‐rich foils with controlled thickness, areal density, and tailored functionality.

The life-cycle and ultrastructure of Sarcocystis ameivamastigodryasi n. sp., in the lizard Ameiva ameiva (Teiidae) and the snake Mastigodryas bifossatus (Colubridae)(1)

open access: yesParasite, 2000
Sarcocysts in muscles of the teiid lizard Ameiva ameivafrom north Brazil were fed to the colubrid snake Mastigodryas bifossatus, the faeces of which had been shown to be devoid of coccidial oocysts or sporocysts.
