Comparative analysis of latex transcriptome reveals putative molecular mechanisms underlying super productivity of Hevea brasiliensis. [PDF]

open access: yesPLoS ONE, 2013
Increasing demand for natural rubber prompts studies into the mechanisms governing the productivity of rubber tree (Heveabrasiliensis). It is very interesting to notice that a rubber tree of clone PR107 in Yunnan, China is reported to yield more than 20 ...

A Soft Robotic Model for Simulating Heart Valve Disease and Cardiac Interventions

open access: yesAdvanced Science, EarlyView.
This paper introduces a fully synthetic fabrication methodology for a soft robotic, in‐vitro model of the left‐heart, complete with a functioning mitral valve apparatus. With a view towards patient‐specific modeling, we demonstrate physiological flow and pressure waveforms, tunable mitral valve function with clinical imaging compatibility, and its use ...

Sustainable rubber production through good latex harvesting practices: stimulation based on clonal latex functional typology and tapping panel management [PDF]

open access: yes, 2013
The purpose of this study was to characterize the long-term behaviour of the rubber tree under different ethephon stimulation treatments and under different panel management strategies.

Somatic embryogenesis as key technology for shaping the rubber tree of the future [PDF]

open access: yes, 2018
Worldwide, Hevea producers face the need to replant large surfaces in the coming years. The rubber yield per ha, produced by trees grafted on heterogeneous illegitimate seedling rootstocks, has reached its maximum.

Physics‐Embedded Neural Network: A Novel Approach to Design Polymeric Materials

open access: yesAdvanced Science, EarlyView.
Traditional black‐box models for polymer mechanics rely solely on data and lack physical interpretability. This work presents a physics‐embedded neural network (PENN) that integrates constitutive equations into machine learning. The approach ensures reliable stress predictions, provides interpretable parameters, and enables performance‐driven, inverse ...

Bioinspired Adaptive Leg‐Claw Enables Robust Perching and Grasping for UAVs

open access: yesAdvanced Science, EarlyView.
Inspired by owl limb morphology and bat roosting behavior, this study presents a bioinspired adaptive leg‐claw mechanism that enables UAVs to perform robust and versatile perching and grasping. The design integrates a four‐link tibial structure, tension‐driven deformable feet, and active control, enabling stable perching on various branches and ...

Effects of Explant Source and Orientation on Secondary Somatic Embryogenesis in Hevea brasiliensis

open access: yesPlants
Propagation of rubber tree (Hevea brasiliensis) via secondary somatic embryogenesis (SSEis) is a reliable method. However, its efficiency is relatively low.

Trees, Tenure and Conflict: Rubber in Colonial Benin [PDF]

open access: yes
Tree crops have changed land tenure in Africa. Farmers have acquired more permanent, alienable rights, but have also faced disputes with competing claimants and the state.

The impact of global changes on agriculture: the case of Ivorian Basin of Comoe River. [P-3330-16] [PDF]

open access: yes, 2015
Since some decades, the Ivorian Comoe river Basin faced environmental and climatic changes. As one of rainfed agriculture leading forces, climate conditions display (here) a major role in agriculture transformations.
