California Agriculture, 1966 Research started in 1961 by agricultural engineers of USDA and University of California has led to commercial acceptance of mechanical harvesting methods with resulting labor and cost savings for California date growers. About 65% of the 1965–66 date crop is expected to be harvested with the aid of various mechanical systems that can reduce labor ...

Detachment efficiency of fruits from coffee plants subjected to mechanical vibrations
Pesquisa Agropecuária Tropical, 2015 The development of efficient machines for the mechanical harvesting of coffee plants requires the use of appropriate vibrational parameters. Thus, in order to detach less unripe fruits and decrease reharvesting, branch breakage and defoliation, it is ...

Emerging role of ARHGAP29 in melanoma cell phenotype switching
Molecular Oncology, EarlyView.This study gives first insights into the role of ARHGAP29 in malignant melanoma. ARHGAP29 was revealed to be connected to tumor cell plasticity, promoting a mesenchymal‐like, invasive phenotype and driving tumor progression. Further, it modulates cell spreading by influencing RhoA/ROCK signaling and affects SMAD2 activity. Rho GTPase‐activating protein

Electro-hydrodynamic synchronization of piezoelectric flags
, 2016 Hydrodynamic coupling of flexible flags in axial flows may profoundly influence their flapping dynamics, in particular driving their synchronization. This work investigates the effect of such coupling on the harvesting efficiency of coupled piezoelectric

Performance measures for single-degree-of-freedom energy harvesters under stochastic excitation [PDF]
, 2014 We develop performance criteria for the objective comparison of different classes of single-degree-of-freedom oscillators under stochastic excitation. For each family of oscillators, these objective criteria take into account the maximum possible energy ...

Modeling hepatic fibrosis in TP53 knockout iPSC‐derived human liver organoids
Molecular Oncology, EarlyView.This study developed iPSC‐derived human liver organoids with TP53 gene knockout to model human liver fibrosis. These organoids showed elevated myofibroblast activation, early disease markers, and advanced fibrotic hallmarks. The use of profibrotic differentiation medium further amplified the fibrotic signature seen in the organoids.
