Weather Attention in Online Discourse and Price Uncertainty in Agricultural Futures Markets

open access: yesAgribusiness, EarlyView.
ABSTRACT Weather is a central determinant of production risk in agricultural markets, but markets respond not only to weather conditions themselves, but also to how those conditions are noticed, framed, and interpreted in public discourse. In this setting, real‐time online weather discussions may shape price uncertainty by influencing how market ...

A Mechanical sp2‐Jail for C60 Fullerene

open access: yesAngewandte Chemie, EarlyView.
A rigid bisporphyrin receptor with an exceptionally compact 3D cavity functions as a molecular “mechanical jail”, tightly enclosing C60 fullerene. Near‐perfect shape complementarity affords ultrahigh binding affinity while imposing a large kinetic barrier for guest exchange, rendering encapsulation effectively irreversible under ambient conditions ...

How much can horizontal head movements influence the real-ear measurement accuracy of open-canal fittings?

open access: yes, 2010
The modified pressure with stored equalisation (MPSE) method of soundfield equalisation is universally recommended for use in clinical practice during the real-ear measurement (REM) verification of open-canal (OC) hearing aids.

Multirobot Aerial Soft Manipulator for Floating Litter Collection

open access: yesAdvanced Intelligent Systems, EarlyView.
A multirobot aerial manipulator enables autonomous floating litter collection by controlling the shape of a flexible rope equipped with a hook‐based tool. Adaptive rope‐shape planning enhances grasping performance while reducing tension, demonstrating the potential of aerial robots for floating litter removal. Removing floating litter from water bodies

Test-retest reliability of real ear measurements for open canal hearing aid fittings

open access: yes, 2010
When fitting hearing aids with conventional earmoulds using real ear measurements (REM) it is recommended to use the modified pressure with concurrent equalization method whereby a reference microphone is used to monitor the REM loudspeaker output level.

Development of an Inchworm‐Like Dual‐Balloon‐Assisted Colonoscopic Robot Based on a Two‐Segment Extensible Continuum Section

open access: yesAdvanced Intelligent Systems, EarlyView.
This work presents an inchworm‐like dual‐balloon‐assisted colonoscopic robot (IDCR) based on a rod‐driven two‐segment continuum section. The IDCR enables the active straightening of the sigmoid colon through an inchworm‐like locomotion strategy, thereby avoiding loop formation.
