An attractive way to improve our understanding of sex determination evolution is to study the underlying mechanisms in closely related species and in a phylogenetic perspective.Hymenopterans are well suited owing to the diverse sex determination mechanisms, including different types of Complementary Sex Determination (CSD) and maternal control sex

Fast neutron therapy has been used for decades.In conjunction with recent advances in photonic techniques, fast neutrons are no longer of iPhone XR/11 much oncologic interest, which is not unequivocally positive, given their undoubted therapeutic value.This mini-review recalls the Removers history of medical research on fast neutrons, considers the

In three-dimensional (3D) digital Earth environment, there are many problems when using the existing methods to express the ocean current, such as uneven distribution of seed points, density leap in scale change and messy visualization.In this paper, a new dynamic visualization method of multi-hierarchy flow field based on particle system is propos

Abstract This paper presents a detailed kinematic and dynamic model of nonuniform skid steering for tracked vehicles on level terrain and uniform skid steering slopes.The objective is to find the required forces applied on both tracks to achieve the desired turning, aiding in determining the needed engine power for effective turning operation.The v
