A amostragem estratificada aprimora a compreensão das redes entre morcegos e frutos na Mata Atlântica meridional

open access: yesOikos, EarlyView.
Few studies have sought to understand the vertical patterns of bat–fruit systems, and therefore, it is not possible to evaluate whether interpretations based on data collected from a single stratum adequately represent the interaction patterns of this system. In this context, we evaluated the dissimilarity in the assemblage of frugivorous bats, plants,

Policy Capacity Matters Differently Over Time: The Emergence and Persistence of Participatory Budgeting in China

open access: yesPublic Administration and Development, EarlyView.
ABSTRACT The persistence of participatory budgeting (PB) in selected Chinese localities challenges the conventional wisdom that deliberative democratic practices can only take root in liberal political environments. Yet, existing literature has not sufficiently elucidated the factors underpinning the rise and sustained operation of PB in this seemingly

Urbanization and food transition in the Brazilian Amazon: From wild to domesticated meat

open access: yesPeople and Nature, EarlyView.
Abstract Urbanization is expected to influence food transitions, resulting in a shift from wild foods to more domesticated foods. Concomitantly, food insecurity and urban demand for natural resources, including wildlife, are expected to increase overall, even when the per capita consumption is expected to decrease.

Forwarding forest restoration: Seven key socio‐ecological issues for advancing forest restoration in a world in flux

open access: yesPeople and Nature, EarlyView.
Abstract Restoring forests can help conserve biodiversity, mitigate climate change and enhance human well‐being. Despite financial and political support for global forest restoration initiatives, projects continue to face persistent challenges and trade‐offs between environmental, climatic and socio‐economic goals.

Piezoresistive Natural Rubber Composites: A Comparison Between Low‐Temperature Glutaraldehyde Curing Agents and Conventional Sulfur Curing Systems

open access: yesPolymer Composites, EarlyView.
The secondary electrical signal peak during cyclic experiment observed in S‐cured NR sensors was eliminated with GA curing due to the homogeneous distribution of crosslink points in the GA‐cured NR network. ABSTRACT This study examines the piezoresistive behavior of natural rubber (NR) composites cured with sulfur (S) and glutaraldehyde (GA) and ...

Impact of Organic and Inorganic Fillers on the Performance of Ternary Biodegradable Poly(Butylene Succinate‐Co‐Butylene Adipate), Poly(Butylene Adipate‐Co‐Terephthalate), and Poly(3‐Hydroxybutyrate‐Co‐3‐Hydroxyvalerate) Blends

open access: yesPolymer Composites, EarlyView.
Development of a ternary blend composite based on PBAT/PBSA/PHVB with improved mechanical properties. ABSTRACT This study explores a ternary biodegradable blend of bio‐based poly(butylene succinate‐co‐adipate) (bio‐PBSA), poly(butylene adipate terephthalate) (PBAT), and poly(3‐hydroxybutyrate‐co‐3‐hydroxyvalerate) (PHBV).

Radiation‐Crosslinked PCL–TMPTA Composites via 3D Printing: Structure–Property Relationships and Shape Memory Performance

open access: yesPolymer Engineering &Science, EarlyView.
3D printed shape memory PCL‐TMPTA through high energy gamma radiation modification. ABSTRACT Programmable materials that can reversibly transform between distinct shapes represent a promising technology for applications spanning biomedicine, robotics, and aerospace engineering. Although shape memory polymers offer promising stimuli‐responsive behavior,

Siamese-rPPG network

Proceedings of the 35th Annual ACM Symposium on Applied Computing, 2020
Remote photoplethysmography (rPPG) is a contactless method for heart rate (HR) estimation from face videos. In this paper, we propose to estimate rPPG signals directly from input video sequences in an end-to-end manner. We propose a novel Siamese-rPPG network to simultaneously learn the heterogeneous and homogeneous features from two facial regions ...
