Records of the Indian Sand Snake Psammophis condanarus (Merrem, 1820) (Reptilia: Lamprophiidae) in southern India

open access: yesJournal of Threatened Taxa, 2017
We present new records of the Indian Sand Snake Psammophis condanarus from southern India, where its existence has remained doubtful till date.  Our records are based on both live and preserved voucher specimens that are illustrated and described here ...

Advancements in Machine Learning for Microrobotics in Biomedicine

open access: yesAdvanced Intelligent Systems, EarlyView.
Microrobotics is an innovative technology with great potential for noninvasive medical interventions. However, controlling and imaging microrobots pose significant challenges in complex environments and in living organisms. This review explores how machine learning algorithms can address these issues, offering solutions for adaptive motion control and ...

Emulating duration and curvature of coral snake anti-predator thrashing behaviors using a soft-robotic platform [PDF]

open access: yesarXiv, 2020
This paper presents a soft-robotic platform for exploring the ecological relevance of non-locomotory movements via animal-robot interactions. Coral snakes (genus Micrurus) and their mimics use vigorous, non-locomotory, and arrhythmic thrashing to deter predation.

Deep Learning Methods in Soft Robotics: Architectures and Applications

open access: yesAdvanced Intelligent Systems, EarlyView.
Soft robotics has seen intense research over the past two decades and offers a promising approach for future robotic applications. However, standard industrial methods may be challenging to apply to soft robots. Recent advances in deep learning provide powerful tools to analyze and design complex soft machines that can operate in unstructured ...

First record of Porocephalus cf. clavatus (Pentastomida: Porocephalida) as a parasite on Bothrops asper (Squamata: Viperidae) in Costa Rica

open access: yesBrazilian Journal of Biology
Pentastomids are parasites that infect respiratory cavities of vertebrates, they are pretty common but poorly known in wildlife veterinary. A Bothrops asper snake (Garman, 1884) was captured in the Caribbean region of Costa Rica and had its lung infested

Purification and partial characterization of phospholipases A2 from Bothrops asper (barba amarilla) snake venom from Chiriguaná (Cesar, Colombia)

open access: yesJournal of Venomous Animals and Toxins including Tropical Diseases, 2004
Components with phospholipase A2 activity were isolated by gel filtration and cationic exchange chromatography from the venom of Bothrops asper snakes from Chiriguaná, Colombia (9°22´N; 73°37´W).

Variational approximations to homoclinic snaking [PDF]

open access: yes, 2010
We investigate the snaking of localised patterns, seen in numerous physical applications, using a variational approximation. This method naturally introduces the exponentially small terms responsible for the snaking structure, that are not accessible via standard multiple-scales asymptotic techniques.

A mid-Cretaceous embryonic-to-neonate snake in amber from Myanmar

open access: yesScience Advances, 2018
The first known fossil baby snake (Late Cretaceous amber, Myanmar) shows that some ancient snakes lived in marginal marine forests. We present the first known fossilized snake embryo/neonate preserved in early Late Cretaceous (Early Cenomanian) amber ...
