Date Time New Study Unveils Phase Synchronization of Fluid-Fluid Interfaces as Hydrodynamically Coupled Oscillators The phenomenon of synchronization is found in many natural and artificial systems, from firefly flashing to the synchronization of two pendulum clocks hanging from a wall. Hydrodynamic interactions also play a role in synchronized motions of coupled oscillators in fluids. Therefore, understanding the mechanism will facilitate development of applications in fluid mechanics. For example, synchronization phenomenon in two-phase flow will benefit the design of future microfluidic de...

Jan 22, 2021 Association of risk seen especially in young patients In patients undergoing appendectomy for acute appendicitis, perioperative abdominopelvic CT — even a one-time exposure — may be associated with an increased risk of hematologic malignant neoplasms, according to results from a nationwide, population-based study from South Korean researchers. “Whether computed tomographic (CT) radiation really induces cancers remains controversial. At least in children and adolescents, the association between CT radiation and carcinogenesis seems plausible given the supporting results of m...

New Method to Estimate Magnetic Hamiltonian Parameters from Spin Structure Images Written by AZoMDec 17 2020 Spintronics is actively studied to overcome the drawbacks of the integration level of silicon semiconductors that are in use at present and to develop ultra-low-power and high-performance next-generation semiconductors. (A) Data generation process showing the sampled spin configurations generated through the simulated annealing process. The color wheel indicates the in-plane magnetization directions, and the grayscale indicates the out-of-plane magnetization directions. (B and C) The t...
