Abstract: An energy storage module includes a bus connection part, a battery pack, a capacitor and a series compensation DC conversion device. A first conduction terminal of the series compensation DC conversion device is electrically connected with a positive bus connection terminal and a negative bus connection terminal of the bus connection part, or the first conduction terminal is connected with a battery positive terminal and a battery negative terminal of the battery pack. A second conduction terminal of the series compensation DC conversion device is electrically connected with two terminals of the capacitor. A four-quadrant DC/DC converter of the series compensation DC conversion device controls the capacitor to generate a compensation voltage to compensate a voltage between the two terminals of the battery pack, or the four-quadrant DC/DC converter adjusts a current flowing through the battery pack to a set value.

Abstract: Disclosed is the use of a combination of an anti-PD-1 antibody and a VEGFR inhibitor in the preparation of a drug for treating cancers.

Abstract: A lipid delivery system, a virus-like structure (VLS) vaccine constructed therefrom, and a lipid particle capable of encapsulating an mRNA molecule encoding a SARS-CoV-2-specific antigen are provided. After the lipid particle encapsulates an mRNA molecule encoding a SARS-CoV-2 antigen, a SARS-CoV-2 S1 antigen protein can be embedded on a surface of an envelope structure of the lipid under specific buffer conditions to produce a VLS vaccine with an antigen-encoding mRNA molecule encapsulated inside and an outer membrane presenting a required viral antigen protein. The vaccine has a superior specific antibody-inducing ability to a SARS-CoV-2 mRNA vaccine and a polypeptide vaccine, can maintain a long-lasting high antibody level, and can also exhibit excellent immune binding abilities for the emerging different variants.

Abstract: A method for grouping lithium secondary battery packs comprises the following steps: charging and discharging a battery for 1-3 cycles, recording the last discharge capacity C0, setting a capacity lower limit, and determining the battery with the C0 thereof not less than the capacity lower limit to be an eligible battery; discharging the battery to a discharge cut-off voltage Vd so the battery is discharged to a power empty state; charging the empty battery to a capacity C1; storing the battery for time t1 in an environment with a temperature ranging between 20-50° C., recording the battery voltage V1, storing the battery again for time t2 in the environment with the temperature ranging between 20-50° C., recording the battery voltage V2, calculating a voltage difference ?V=V2?V1 and setting the range of ?V; and grouping eligible batteries in a previous step according to a certain capacity grouping standard.

Abstract: Methods and systems for detecting oil proximate to a body of ice is disclosed herein. An example system includes an energy emitter disposed proximate to a first surface of a body of ice. An energy detector is disposed proximate to a second surface of the body of ice. The energy detector is used to map a distribution of oil proximate to the body of ice based, at least in part, on differences in energy transmitted through the body of ice.

Abstract: Method and system is described for enhanced oil release management system by using one or more booms, one or more skimmers and one or more floating burners. The method and system may include skimmers to capture a fluid that is supplied to the floating burner.
