Abstract Applying Bikinis strong direct current (DC) electric fields on the apex of a sharp metallic tip, electrons can be radially emitted from the apex to vacuum.Subsequently, they magnify the nanoscopic information on the apex, which serves as a field emission microscope (FEM).When depositing molecules on such a tip, peculiar electron emission p
Introduction: Eruption of central incisors occurs at a time when the mixed dentition starts to develop and their impaction is mostly a severe esthetic problem.Aim: Our aim Hose End Coupling was to assess the frequency of impaction of an upper central incisor and to analyse the factors which affect the successful outcome and the protocols for orthod
Most machine learning algorithms only have a good recognition rate on balanced datasets.However, in the field of malicious traffic identification, benign traffic on the network is far greater than malicious traffic, and the network traffic dataset is imbalanced, which makes the algorithm have a low identification rate for small categories of malici
Paleobotanists debate whether the Cretaceous/Paleogene boundary (KPB) event was selective.As the hypothesis that the KPB event selected for plants with fast-return leaf economic traits (e.g.deciduousness) has lost empirical support in recent investigations, researchers have turned to alternative hypotheses to explain an abrupt decline in primary pr
