A New Species of the Asian Toad Genus Megophrys sensu lato(Amphibia: Anura: Megophryidae) from Guizhou Province, China [PDF]

open access: yes, 2018
We describe a new species of the genus Megophrys sensu lato from Guizhou Province, China. Molecular phylogenetic analyses based on mitochondrial DNA and nuclear DNA sequences all strongly supported the new species as an independent lineage in Megophrys ...

Laparoscopic resection of unruptured rudimentary horn pregnancy

open access: yesJournal of Gynecological Endoscopy and Surgery, 2011
A non-communicating rudimentary horn is an uncommon site for ectopic pregnancy. Rudimentary horn pregnancy (RHP) is a rare entity but associated with grave clinical consequences. Majority of these cases if not detected timely end up in uterine rupture and present as an obstetrical emergency.

Ontogenetic changes and sexual dimorphism in the cranium and mandible of the Atlantic walrus (Odobenus rosmarus rosmarus L.)

open access: yesThe Anatomical Record, EarlyView.
Abstract Walruses have been an important subsistence and cultural resource for humans and have been exploited for millennia across their distribution. This exploitation has contributed to severe declines in several populations and local extirpations.

Diagnosis and laparoscopic management of a 5-week ectopic pregnancy in a rudimentary uterine horn: A case report

open access: yesCase Reports in Women's Health, 2019
Uterine anomalies result from the failure of complete fusion of the Müllerian ducts during embryogenesis. A unicornuate uterus with a rudimentary horn is the rarest anomaly and results from the failure of one of the Müllerian ducts to develop completely ...

Encoding Spatial Experience in Garhwali Popular Music Cassettes [PDF]

open access: yes, 2018
Connections between particular sounds and geographically conceived places/spaces seems to be a recurrent part of many repertoires in different parts of the Himalaya. A number of examples exist in which ritual repertoires are linked to pilgrimage pathways,

A detailed redescription of a skeletally immature ‘Redondasaurus’ suggests ontogenetic transformations in the taxon mirror phytosaurian morphological evolution

open access: yesThe Anatomical Record, EarlyView.
Abstract The study of morphological evolution is fundamentally tied to ontogeny, yet studies of these heterochronic processes in the fossil record are rare. Fossils belonging to an ontogenetic series are difficult to assign to an ontogenetic stage due to inconsistent proxies for skeletal ages, challenging to taxonomically assign due to morphological ...

Variations in clinical presentation of unicornuate uterus with non-communicating rudimentary horn (class IIB of the American Fertility Society classification)

open access: yesTaiwanese Journal of Obstetrics & Gynecology, 2018
Objective: The unicornuate uterus is a rare uterine malformation (2.4–13.7% of all uterine malformations (Engmann et al., 2004)) which usually features a rudimentary accessory horn in more than 75% of the cases. Pregnancy in the rudimentary horn is rare,

Growth dynamics, skeletochronology, and histovariability of the theropod dinosaur Berthasaura leopoldinae

open access: yesThe Anatomical Record, EarlyView.
Osteohistological sampling on different bones of theropod dinosaur documents discrepant age record, growth, and metabolism. This could result unprecise paleobiological inferences if samplings are based on single bones. However, multi‐bone sampling can attenuate these discrepancies, helping to infer growth dynamics and physiology of these extinct ...

QCSP on partially reflexive cycles - the wavy line of tractability

open access: yes, 2013
We study the (non-uniform) quantified constraint satisfaction problem QCSP(H) as H ranges over partially reflexive cycles. We obtain a complexity-theoretic dichotomy: QCSP(H) is either in NL or is NP-hard.
