ROS-X-Habitat: Bridging the ROS Ecosystem with Embodied AI [PDF]

open access: yesarXiv, 2021
We introduce ROS-X-Habitat, a software interface that bridges the AI Habitat platform for embodied learning-based agents with other robotics resources via ROS. This interface not only offers standardized communication protocols between embodied agents and simulators, but also enables physically and photorealistic simulation that benefits the training ...

Predicting local and non-local effects of resources on animal space use using a mechanistic step selection model [PDF]

open access: yesMethods Ecol Evol (2014) 5(3):253-262, 2015
1. Predicting space use patterns of animals from their interactions with the environment is fundamental for understanding the effect of habitat changes on ecosystem functioning. Recent attempts to address this problem have sought to unify resource selection analysis, where animal space use is derived from available habitat quality, and mechanistic ...

Transmembrane Activation of Catalysis and Protein Refolding in Synthetic Cells by Enzymes and Nanozymes

open access: yesAdvanced Functional Materials, EarlyView.
Synthetic cells are engineered herein to respond to an external chemical messenger by the activation of intracellular catalysis. The chemical messenger molecules are catalytically generated by an extracellular enzyme or a mineral surface, whereas the intracellular catalysis emerges via direct enzyme activation or via protein refolding.

Enhancing security of land tenure for IDPs

open access: yesForced Migration Review, 2014
"The case of Maslakh in western Afghanistan is an example of translating Afghanistan’s new IDP Policy into reality. If successful the project will ensure security of land tenure for IDPs in urban settings and set a precedent for local integration of IDPs

Placing Green Bridges Optimally, with Habitats Inducing Cycles [PDF]

open access: yesarXiv, 2022
Choosing the placement of wildlife crossings (i.e., green bridges) to reconnect animal species' fragmented habitats is among the 17 goals towards sustainable development by the UN. We consider the following established model: Given a graph whose vertices represent the fragmented habitat areas and whose weighted edges represent possible green bridge ...

Stress Response of Aspergillus niger Spores to Copper Surfaces and the Implications for Antifungal Surface Functionalization

open access: yesAdvanced Materials Interfaces, EarlyView.
This study investigates the antifungal efficacy of ultrashort pulsed laser‐induced periodic surface structures (USP‐DLIP) on copper, brass, and steel surfaces. Using Aspergillus niger as a model, the research highlights a 99% reduction in spore viability on 9 µm structured copper surfaces due to enhanced copper ion release. Scanning electron microscopy

The recent decline of Montastraea annularis (complex) coral populations in western Curaçao: a cause for concern?

open access: yesRevista de Biología Tropical, 2006
Shallow leeward reefs off the western end of Curaçao are dominated by extensive populations of M. annularis (complex). These species are larger in size (mean= 66 cm diameter) than all other species, with few small colonies (10 cm observed within ...

Measuring E-Service Quality In Agriculture Company

open access: yesHabitat, 2020
Nowadays, E-Service Quality is known to be one of the keys that determines e-commerce success. Delivering quality in service becomes a very important strategy for marketers who try to offer different services in order to be able to compete with other ...

Inferring habitat quality and habitat selection using static site occupancy models [PDF]

open access: yesarXiv, 2016
When evaluating the ecological value of land use within a landscape, investigators typically rely on measures of habitat selection and habitat quality. Traditional measures of habitat selection and habitat quality require data from resource intensive study designs (e.g., telemetry or mark-recapture).

Ecology and co-existence of two endemic day gecko (Phelsuma) species in Seychelles native palm forest [PDF]

open access: yes, 2011
In island ecosystems, reptiles play diverse ecological roles as a result of niche broadening, which increases potential niche overlap between species. Ecological niche partitioning is a means of reducing direct competition between coexisting species and ...
