Molecular clock and biogeochemical evidence indicate that the dinoflagellate lineage diverged at around 650 Ma.Unequivocal dinoflagellate cysts/zygotes appeared during the Triassic.These biotas were badly affected by the end-Triassic extinction and recovery from this was relatively slow.During the early Middle Jurassic, the family Gonyaulacaceae un
Maintenance Therapy in First-Line Gastric and Gastroesophageal Junction Adenocarcinoma: A Retrospective Analysis
BackgroundFluoropyrimidine with platinum-based chemotherapy has become the standard of care for advanced gastric and gastroesophageal (GEJ) cancer.Trials in colon cancer show that induction chemotherapy followed by maintenance chemotherapy is an efficacious strategy to maximize clinical response while minimizing toxicity.The current retrospective s
Path planning of mine robot based on a novel heuristic algorithm with regular hexagon grids
In the traditional square grid map, when robot encounters an obstacle, it is easy to collide with the obstacle when moving along diagonal direction, has poor capability in obstacle-avoiding and stability, and time consumed in each step during real-time detection cannot be uniquely determined.In view of the above problems, based on working environme
The SARS-COV-2 pandemic and the challenges of intellectual property rights
The COVID-19 virus pandemic equi jec 7 had a drastic impact on the social lives of billions of people, hitting certain industries like a hurricane.What the answer will be to this and possible other occurrences of pandemics in the future will largely depend on the inventiveness of the researchers.Intellectual property is the first system to offer an
