Abstract: The invention provides a cancer early detection method using liquid biopsy, the cancer early detection method includes the following steps. MicroRNA expression profile database of cancer patient populations and healthy populations are established. Afterwards, an analysis model for cancer early detection is established through the following steps: a data quality control, a technical replicate merging, a calculation of normalization factors and data normalization, a biomarker feature selection, and a hyperparameter tuning. The analysis model for cancer early detection includes normalization factors, a set of biomarkers, model weights and model hyperparameters. A microRNA expression profile in a liquid biopsy sample of a subject is analyzed by the analysis model for cancer early detection to be used as a basis for an early detection of cancer.

Abstract: A cooling device includes a first surface portion thermally connected to one or more heating elements, a second surface portion opposed to the first surface portion, a flow path between the first and second surface portions and through which the cooling fluid flows, and a side wall connecting the first and second surface portions and extending along the direction in which the cooling fluid flows. A height of the side wall is reduced from the second surface portion side toward the first surface portion side at an outlet of the flow path. At least a portion of the second surface portion is missing in a portion of the side wall of which the height is reduced. A portion where the side wall is in contact with the first surface portion is superimposed on at least an entirety of the heating element closest to the outlet of the flow path.

Abstract: An all-terrain vehicle has a frame unit including upper side tubes and lower side tubes. Front and rear ancillary tube assemblies are connected between the upper side tubes and the lower side tubes in the front and rear parts. A power unit is fixed to the lower side tubes. A heat dissipation member for cooling the power unit is mounted to the front part of the frame unit. The power unit has an air inlet port to which a cooling duct is coupled. A steering mechanism is arranged in an internal area delimited by the upper side tubes and the lower side tubes between the heat dissipation member and the power unit and includes a steering bar, an electronic steering assisting device, and a steering arm. The cooling duct and the electronic motor are respectively set on opposite sides of a steering bar center axis of the steering mechanism.

Abstract: An electrolyte for a rechargeable battery includes 20-70% by volume of at least two cyclic carbonates selected from ethylene carbonate, propylene carbonate, vinylene carbonate or butylenes carbonate, 30-80% by volume of an ester selected from propyl propionate, propyl acetate, butyl acetate or a mixture thereof, and a lithium salt.
