Transducers Across Scales and Frequencies: A System‐Level Framework for Multiphysics Integration and Co‐Design

open access: yesAdvanced Materials Technologies, EarlyView.
Transducers convert physical signals into electrical and optical representations, yet each mechanism is bounded by intrinsic trade‐offs across bandwidth, sensitivity, speed, and energy. This review maps transduction mechanisms across physical scale and frequency, showing how heterogeneous integration and multiphysics co‐design transform isolated ...

Chemically Doped Conductive Polymers for Wearable Health Monitoring

open access: yesAdvanced Materials Technologies, EarlyView.
Among conductive polymers, poly(3,4‐ethylenedioxythiophene):poly(styrenesulfonate) (PEDOT:PSS), polyaniline (PANI), and polypyrrole (PPy) are the most studied and applied. Chemical doping significantly boosts intrinsic conductivity and mechanical robustness.

Effect of contract farming on the U.S. crop farmers' average return

open access: yesAgricultural Economics (AGRICECON), 2013
In the literature of contract farming, most of the studies focus on the functions of risk managements and reducing transaction costs. Only a few study the effect of contract farming on the productivity efficiency or profitability.

Multiobjective Codesign Optimization of a Planar Pneumatic Artificial Muscle‐Based Snake‐Like Robot for Enhanced Agility and Energy Efficiency

open access: yesAdvanced Robotics Research, EarlyView.
A codesign multiobjective optimization framework was developed to enhance the morphology and controller of a snake‐like robot driven by artificial muscles. It improved planar locomotion, agility, and power efficiency. The approach optimized link geometry and controller gains, revealing that shorter muscles near joints and longer linkages maximize ...

Rice contract farming in Cambodia: Empowering farmers to move beyond the contract toward independence [PDF]

open access: yes, 2008
From the farmer's perspective, contract farming provides stable market access, credits, extension services, infrastructure and other benefits, but has drawbacks such as limiting the flexibility of farming and marketing. Based on a survey of rice contract

Temporal and Cell‐Specific Regulation of Synaptic Homeostasis by the Chromatin Remodeler Chd1

open access: yesAdvanced Science, EarlyView.
Chd1, the Drosophila homologue of mammalian CHD2 ‐ a gene linked to autism, epilepsy, and intellectual disability, is required for synaptic homeostatic plasticity. Chd1 in glia is necessary for the rapid induction of synaptic homeostasis, whereas Chd1 in motoneurons, muscle, and glia is critical for long‐term maintenance.

Farmer’s literacy and contract farming participation in Tanzania’s cash crops agriculture: application of human capital theory

open access: yesDiscover Agriculture
Participation in contract farming has the potential to enhance farmers’ income and livelihoods both in developed and developing countries, yet the influence of literacy levels on such agri-systems remains insufficiently explored.

Bioenergy Cropping Reduces the Spatiotemporal Scaling of Soil Bacterial Biodiversity

open access: yesAdvanced Science, EarlyView.
Consistent with patterns observed in plant and animal communities, soil bacterial communities exhibit significant species–time–area and phylogenetic–time–area relationships independent of nested structure. Bioenergy cropping significantly reduces the spatiotemporal scaling rates, particularly in sandy loam soils.
