Agribusiness, EarlyView.ABSTRACT Using survey and discrete choice experiment data, we examined US specialty crop growers' preferences for marketing contract attributes in the context of emerging blockchain‐based technologies and expanding traceability initiatives. Results show that farmers preferred traditional written contracts but might be willing to accept digital ...

Precession-Nutations and Tidal Potential [PDF]
International Astronomical Union Colloquium, 1971 We have previously established (Melchior and Georis, 1968) the equations connecting the development of precession-nutation with the tesseral part of the tidal potential. These equations are:whereωiAirespectively represent the frequencies and amplitudes of the tidal waves, ω the Earth’s rotation velocity,

Vision‐Based Tactile Finger Integrating Fingerpad and Nail Sensing for Robotic Manipulation
Advanced Intelligent Systems, EarlyView.This vision‐based tactile finger captures nail force and fingerpad force, contact position, and in‐plane orientation with one internal camera. An external camera recognizes the target and presets finger inclination from object height. The compact dual‐sensing design supports tactile‐guided table contact and reliable grasping of objects ranging from ...

Climate change and perennial crop production: Evidence of yield impact and adaptation in California
American Journal of Agricultural Economics, EarlyView.Abstract Perennial crops are economically important. They contribute to food security, providing essential nutrients that are often lacking in annual crops, and provide additional environmental benefits compared with annual crops. Despite their importance, empirical research on the impacts of climate change and adaptation on perennial crops remains ...

International Forum of Allergy &Rhinology, EarlyView.ABSTRACT Background Healing dynamics after anterior skull base (ASB) reconstruction following transnasal endoscopic surgery (TES) for sinonasal malignancies remain poorly characterized. This study aimed to describe the postoperative healing process, quantify time to healing, identify factors influencing healing, and assess radiologic evolution over ...

Nutation damping of dynamically tuned gyroscopes
MATEC Web of Conferences, 2017 The paper deals with the problem of nutation damping of dynamically tuned gyroscopes (DTG). Unlike the common two-axis gyroscopes, the DTG damping torques caused by dry and viscous frictions are absent in gimbal bearings, while those due to the rotor ...

Some difficulties in the theory of nutation [PDF]
Geophysical Journal International, 1978 Fedorov (1958) made a splendid discussion of data on the nutations; Vicente and I made a theory, taking account of a fluid core and of an elastic shell. The agreement was far better than had been found before, but some inconsistencies remained.
