Vision-Based Early Fault Diagnosis and Self-Recovery for Strawberry Harvesting Robots
Announce Type: replace Abstract: Strawberry-harvesting robots faced challenges such as poor visual perception, gripper misalignment, empty grasp/misgrasp, and slippage, which reduced harvesting stability and efficiency. To overcome these issues, this paper proposes a visual fault diagnosis and self-recovery framework. An end-to-end SRR-Net achieved unified perception and fault diagnosis through joint detection, segmentation, and ripeness regression of the fruit and gripper.
Minimization of disorder as a key design principle for natural sizes of light harvesting 2 complexes
arXiv:2606.10103v1 Announce Type: new Abstract: The light harvesting 2 (LH2) complex of purple bacteria has excellent energy conversion efficiency. Clarifying the design principle behind such efficiency at the atomistic level is crucial for understanding its structure-function relationship, and can be utilized for the design of artificial light harvesting systems. To this end, we conducted comprehensive computational investigation of the dynamical and statistical nature of electronic excited...
Roles of individual pigments in ultrafast excitation dynamics of light-harvesting phycobiliproteins revealed by recombinant techniques and two-dimensional electronic spectroscopy
Announce Type: replace Abstract: Phycobiliproteins serve as highly efficient light-harvesting antennae in cyanobacteria, yet the molecular factors governing their ultrafast energy relaxation and coherence dynamics remain incompletely understood. In this study, we investigate the role of pigment arrangement and pigment-protein interactions by combining recombinant protein engineering with two-dimensional electronic spectroscopy (2D-ES). In addition to wild-type allophycocyanin (APC) and...
Monsoon rain reaches Kerala 3 days late but on time to save Indian harvests
Monsoon rain reaches Kerala 3 days late but on time to save Indian harvests The monsoon rains are essential for driving India’s $4 trillion economy. Monsoon rains have arrived in India’s southeastern state of Kerala three days late, the Meteorological Department says. The rains typically arrive on June 1 and are critical to India’s economic health, enabling farmers to plant cotton, soya beans, sugarcane, rice and corn.
Why many fungicide-treated soybean seeds may boost harvests but not farm profits
Why many fungicide-treated soybean seeds may boost harvests but not farm profits Gaby Clark Scientific Editor Andrew Zinin Lead Editor Many soybean farmers use seeds treated with fungicides to ward off disease, but the profits from these increased yields might not offset the cost of the treatment in most cases, according to a study published in Scientific Reports by researchers at Penn State. The researchers analyzed how seed treatments affect yield and profitability in soybean farms in the...
Clipped Affine Policy: Low-Complexity Near-Optimal Online Power Control for Energy Harvesting Communications over Fading Channels
arXiv:2601.07622v2 Announce Type: replace Abstract: This paper studies online power control for battery-limited point-to-point energy harvesting communications over slow block-fading channels. A linear-policy-based approximation is developed for the relative-value function in the Bellman equation of the power control problem. This approximation leads to two fundamental parameterized clipped affine policies: an optimistic policy derived from a certainty-equivalence-type approximation and a...

Country diary: Ladybirds and wasps are the unsung heroes of the farm | Colin Chappell
Brigg, Lincolnshire: With harvest approaching, we’re putting the glorious long evenings to good use, and both humans and insects are working hard to protect the cropsThere’s something magical about the long evenings in June, the warmth and the way the setting sun casts long shadows across the fields. The extra hours are much-needed though as there is plenty to do. We’re in the run-up to harvest in July, so if the weather is dry we walk up and down the seed crop tramlines, pulling...
Intercomparison of Machine Learning Algorithms for Remote Sensing-based In-season Crop Mapping
arXiv:2606.05731v1 Announce Type: new Abstract: In-season crop type mapping is critical for food security in the face of increasingly extreme climate-related threats to crops. Currently, the USDA Cropland Data Layer provides crop type labels at 30m resolution and is available the February after harvest, but no product exists that maps crop types before harvest with satisfactory accuracy that would allow emergency managers to respond to crop threats in near real time.
