Description of Karyotype of Kerodon acrobata, an endemic rodent in Brazilian Cerrado

open access: yesBrazilian Journal of Biology
Kerodon acrobata is a caviidae rodent endemic from Brazilian Cerrado. It was described only in 1997 and the data about it is very scarce. The aim of this work was to characterize the karyotype of K. acrobata.

Ergodic Transport Theory, periodic maximizing probabilities and the twist condition [PDF]

open access: yes, 2013
The present paper is a follow up of another one by A. O. Lopes, E. Oliveira and P. Thieullen which analyze ergodic transport problems. Our main focus will a more precise analysis of case where the maximizing probability is unique and is also a periodic ...

Species and site contributions to Odonata adult assemblage uniqueness in Brazilian Amazon streams

open access: yesJournal of Insect Conservation
Abstract Studies that assess the contribution of sites (LCBD) and species (SCBD) to total beta diversity (BDtotal) along environmental/spatial gradients are of fundamental importance for biodiversity knowledge, species conservation and for environmental restoration. We analyzed which spatial, environmental and environmental heterogeneity (LCEH)

Exploring the Potential of Zero‐Dimensional Carbon Nanomaterials in Photoluminescent, Electrochemiluminescent and Electrochemical Sensors

open access: yesAdvanced Materials Interfaces, EarlyView.
Zero‐dimensional carbon nanomaterials are presented as multifunctional platforms linking structure, property, and sensing performance. Surface engineering and heteroatom doping modulate electron‐transfer and luminescent behavior, enabling electrochemical, photoluminescent, and electrochemiluminescent detection. Fundamental design principles, analytical

Existence, Uniqueness and Comparison Results for BSDEs with L\'evy Jumps in an Extended Monotonic Generator Setting

open access: yes, 2018
We show existence of a unique solution and a comparison theorem for a one-dimensional backward stochastic differential equation with jumps that emerge from a L\'evy process.

Microwave Absorption for Detection of Dirac Fermions in SnTe Films

open access: yesAdvanced Materials Interfaces, EarlyView.
Microwave absorption can detect Dirac fermions in samples exposed to the atmosphere. Results showed that although topological surface states are robust against environmental degradation, they are not detectable by electrical transport measurements. Hence, microwave absorption can detect Dirac fermions even in samples whose surfaces have deteriorated ...

A Perspective on the Applications of Triphasic Gas Storage in Electrochemical Systems

open access: yesAdvanced Science, EarlyView.
Gas storage in microporous materials positioned locally at an electrode or electrocatalyst surface enhances electrochemical processes. Abstract Microporous materials store gases under dry conditions (e.g., hydrogen or oxygen via physisorption), but in some cases microporous materials also show triphasic (e.g., in a solid|gas|liquid system) gas storage ...
