WHITE OAK (QUERCUS FABRI HANCE) REGENERATED STUMP SPROUTS SHOW FEW SENESCENCE SYMPTOMS DURING 40 YEARS OF GROWTH IN A NATURAL FOREST

White oak (Quercus fabri Hance) regenerated stump sprouts show few senescence symptoms during 40 years of growth in a natural forest

Abstract Background The relationship between physiological age of parental trees and lifespan of clonal offspring is unclear.White oak (Quercus fabri Hance) has a high sprouting capability after harvest, with the regenerated sprouts being typical clonal individuals.To determine whether regenerated sprouts undergo rapid senescence compared with the

CDKN2A Copy Number Loss Is an Independent Prognostic Factor in HPV-Negative Head and Neck Squamous Cell Carcinoma

BackgroundHPV infection is associated with high p16 expression and good prognosis in head and neck squamous cell carcinomas (HNSCCs).Analysis of CDKN2A, the gene encoding p16, may further elucidate the association between p16 expression and Tall Barstool prognosis.We sought to determine whether CDKN2A copy number loss was associated with poor survi

Thrust Prediction of an Active Flapping Foil in Waves Using CFD

A horizontally submerged passive flapping foil can generate thrust force against the wave propagation using wave energy.This renewable method has been used for the design of propulsion and maneuvering systems of ships and other floating structures.Recently, the passive flapping foils were applied to design the station-keeping system of deep-water f
