Abstract: A marine floating body is provided with an air chamber, and is configured to float on a sea surface. A wall structure enclosing the air chamber includes a top wall and a side wall. The top wall is fixedly provided with a photovoltaic assembly. The side wall is provided with an inlet check valve. The marine floating body is configured to submerge under large waves to avoid impact and to resurface automatically when conditions calm. A redundant buoyancy of the marine floating body array is controlled so that, under extreme weather, a wind pressure generated by large waves exceeds the buoyancy, causing the array to submerge, and the array resurfaces when the wind and waves diminish. A marine floating body array with a wave-breaking baffle, and a wind-wave resisting method using the same are also provided.

Abstract: Disclosed are methods for obtaining genome scale and fully phased epigenetic maps in a cell. The method enables maintaining intact chromatin structure and interrogating chromatin structure using chromatin accessibility maps. DNA contacts are used to fully phase the epigenetic and chromatin contact maps.

Abstract: Disclosed are methods for detecting spatial proximity relationships between nucleic acid sequences, such as genomic DNA, in a cell. The method includes providing a sample of one or more crosslinked cells comprising nucleic acids; permeabilizing isolated nuclei under conditions that preserve contacts; fragmenting the nucleic acids present in the nuclei; filling in and repairing the ends with at least one labeled nucleotide; joining the filled in end of the fragmented nucleic acids that are in close physical proximity to create one or more end joined nucleic acid fragments having a junction; isolating the one or more end joined nucleic acid fragments using the labeled nucleotide; and determining the sequence at the junction of the one or more end joined nucleic acid fragments.
