A Comparison of Non-Isolated High-Gain Three-Port Converters for Hybrid Energy Storage Systems

open access: yesEnergies, 2018
This work carries out a comparison of non-isolated topologies for power electronic converters applied to Hybrid Energy Storage Systems. At the considered application, several options for three-port circuits are evaluated when interfacing a DC link with ...

Antibiotic Resistance Genes in Lemur Gut and Soil Microbiota Along a Gradient of Anthropogenic Disturbance

open access: yesFrontiers in Ecology and Evolution, 2021
The overuse of man-made antibiotics has facilitated the global propagation of antibiotic resistance genes in animals, across natural and anthropogenically disturbed environments.

Shortest known prion protein allele in highly BSE-susceptible lemurs [PDF]

open access: yes, 2000
We describe the shortest prion protein allele known to date. Surprisingly, it is found as a polymorphism exactly in a species (prosimian lemurs) which seems highly susceptible to oral infection with BSE-derived prions. The truncation of the prion protein

Toxoplasmosis in Captive Ring-Tailed Lemurs (Lemur catta)

open access: yesPathogens, 2022
Toxoplasma gondii is one of the most common protozoan parasites and is widely present in all warm-blooded animals. Although clinical disease is uncommon, some species, including ring-tailed lemurs (Lemur catta), have been found to develop acute and lethal toxoplasmosis.

MapReduce for information retrieval evaluation: "Let's quickly test this on 12 TB of data" [PDF]

open access: yes, 2010
We propose to use MapReduce to quickly test new retrieval approaches on a cluster of machines by sequentially scanning all documents. We present a small case study in which we use a cluster of 15 low cost machines to search a web crawl of 0.5 billion ...

Drug-Resistant Tuberculosis in Pet Ring-Tailed Lemur, Madagascar

open access: yesEmerging Infectious Diseases, 2021
We diagnosed tuberculosis in an illegally wild-captured pet ring-tailed lemur manifesting lethargy, anorexia, and cervical lymphadenopathy. Whole-genome sequencing confirmed the Mycobacterium tuberculosis isolate belonged to lineage 3 and harbored ...

Touchscreen-based cognitive tasks reveal age-related impairment in a primate aging model, the grey mouse lemur (Microcebus murinus) [PDF]

open access: yes, 2014
Mouse lemurs are suggested to represent promising novel non-human primate models for aging research. However, standardized and cross-taxa cognitive testing methods are still lacking.

Assessing the prevalence of protected species consumption by rural communities in Makira Natural Park, Madagascar, through the unmatched count technique

open access: yesConservation Science and Practice, 2021
In tropical Africa, wild meat consumption by rural communities who live in or near protected areas can be a major challenge in the conservation of threatened species. Lemurs and the fossa are among the species consumed in Makira Natural Park, Madagascar.

Interspecies Papillomavirus Type Infection and a Novel Papillomavirus Type in Red Ruffed Lemurs (Varecia rubra)

open access: yesViruses, 2023
The Papillomaviridae are a family of vertebrate-infecting viruses of oncogenic potential generally thought to be host species- and tissue-specific. Despite their phylogenetic relatedness to humans, there is a scarcity of data on papillomaviruses (PVs) in
