Abstract: A cushion with heat preservation, cold insulation and freshness preservation functions is provided, relating to the technical field of home and outdoor patio leisure products. The cushion includes an outer cover and an inner core, as well as a containing bag located in the inner core. The bag body of the containing bag is provided with an insulation layer, and the opening of the containing bag corresponds to the first opening and closing structure of the outer cover. In outdoor camping and other scenarios, items that need heat preservation can be placed in the containing bag, which can reduce the number and volume of items needed to be carried, making them easy to carry, on the other hand, items such as food can also be insulated and kept fresh, making it convenient for users.

Abstract: To achieve the above objective, the present invention provides the following technical solution: a handheld magnifier with an adjustable focal length, comprising an upper shell and a lower shell. The upper shell is equipped with a protection plate, a display screen, and a silicone key, while the lower shell contains a PVC film. A battery, a keyboard, a main board, a wave wheel, a sector gear, a lens assembly, and a light board are installed between the upper and lower shells. The lens assembly consists of an FPC cable, a chip, a guide fixing seat, a roller, a lens holder, a lens cover, and a glass sheet. Manual precise focusing is achieved through a mechanical transmission structure consisting of a wave wheel, sector gear, and spiral groove. This structure provides a wide adjustable range of clarity to accommodate observation needs at different distances.

Abstract: The embodiments of the present disclosure provide a method for processing entrained slag inclusions in steel with deoxidized calcium with fixed aluminum. The method proposes a kinetic model and further proposes a criterion for determining which composition of inclusions are the entrained slag inclusions based on the process of compositional transformation of the entrained slag inclusions. The method can clarify whether the inclusions in the steel are entrained slag or not, identify the source of the inclusions, and further provide a clear direction for the control of such inclusions in industrial production. Corresponding industrial measures can then be implemented to adjust steelmaking processes, control the occurrence of entrained slag inclusions, reduce the count of entrained slag inclusions in steel, and enhance process efficiency and steel product quality.

Abstract: The present disclosure provides an illuminated cushion. The illuminated cushion comprises an outer cover, a soft core, a power supply unit, and a light strip. The outer cover envelops the soft core, the power supply unit supplies power to the light strip, and the light strip is arranged inside piping and/or a decorative trim on lateral edges of the outer cover. By embedding the light strip within the piping and/or decorative trim, the light strip is hidden inside, adding a lighting function to the cushion without altering its external appearance. The light strip can outline the cushion, making it easier to find while also providing lighting and enhancing the ambiance.

Abstract: The present invention provides for methods of using kits and methods for attaching cells to a biosensor surface (5) of a biosensor (4) comprising: providing a cell suspension in a liquid receiving unit (1), wherein the cell suspension forms a surface (7) to the exterior of the liquid receiving unit (1); contacting the biosensor surface (5) with the surface (7) of the cell suspension in the liquid receiving unit (1); and allowing the cells to settle on the biosensor surface (5) by gravity, and allowing the cells to adhere to the biosensor surface (5).

Abstract: In some implementations, a radiofrequency down converter comprises an input port to receive a radiofrequency input signal, and the down converter includes a first bandpass filter configured to filter the input signal. The down converter includes a mixer stage coupled to the bandpass filter, the mixer stage being configured to generate a mixer output signal by processing the filtered input signal using a gain adjustment device, one or more amplifiers, and a mixer. The down converter includes a signal adjustment stage coupled to receive the mixer output signal, the signal adjustment stage comprising: a temperature compensation device configured to compensate for changes in signal gain due to changes in temperature; a second bandpass filter; a gain adjustment device; one or more amplifiers; and a low pass filter. The down converter comprises an output port coupled to output an adjusted mixer output signal from the signal adjustment stage.

Abstract: The present disclosure relates to unimolecular core-shell nanoparticle, nanoclusters thereof, and platelet biomimetic nanoclusters thereof. The disclosed compositions are useful for treating a subject with a disease or condition, such as a cardiovascular disease. In a further aspect, the cardiovascular disease can be a vascular stenosis or restenosis. Also described herein are methods of making and using the unimolecular core-shell nanoparticle, nanoclusters thereof, and platelet biomimetic nanoclusters thereof. This abstract is intended as a scanning tool for purposes of searching in the particular art and is not intended to be limiting of the present disclosure.

Abstract: A cushion is provided, which relates to the technical field of home and outdoor patio leisure products, including a cover, a soft core, a power supply unit, a sounder, and a luminescent strip; the cover wraps around the soft core, the sounder is arranged in the soft core, and the luminescent strip is arranged inside the margin edge strip and/or a decorative edge of the side of the cover and powered by the power supply unit.
