Abstract: The disclosure relates to methods, compositions, and kits for the early determination of the sex of a fetus. The disclosure also provides methods, compositions, and kits for detecting fetal nucleic acids in biological samples (e.g., cell-free fetal DNA). An embodiment includes a method of improving the accuracy of fetal sex determination by reducing a level of contaminating DNA in a blood sample from a pregnant human subject, comprising obtaining a capillary blood sample collected from the upper arm using a push-button blood collection device, thereby reducing a level of contaminating DNA from a non-maternal and non-fetal source in the capillary blood sample as compared to a blood sample collected from a site on the finger or hand of the subject, and detecting the presence or absence of fetal Y-chromosome to determine the sex of the fetus.

Abstract: An applicator includes a brush handle and at least two branches. The inner walls of the at least two branches enclose a cavity. Each of the branches includes at least two brush strips. First ends of the brush strips are fixedly connected to the brush handle. Second ends of the brush strips are free ends. Two adjacent brush strips in each of the branches are fixedly connected through a connecting bridge. Protrusions are respectively arranged on the brush strips. The cavity is formed in the applicator. The cavity can carry a large amount of a cosmetic. Therefore, a cosmetic carrying capacity of the applicator is improved to make a user dip the cosmetic from the cosmetic bottle less frequently and achieve convenience in use and a higher makeup efficiency.

Abstract: A cosmetic applicator includes a brush rod. The brush rod includes a grip portion and an application portion. The application portion includes a first surface and a second surface. A thin-film layer is fixedly provided on the first surface, and an accommodating cavity is formed between the thin-film layer and the first surface. With the thin-film layer and the accommodating cavity between the thin-film layer and the application portion, when the application portion is pulled out of a cosmetic bottle, not only can the flocking layer carry the cosmetic, but the accommodating cavity covered by the thin-film layer stores the cosmetic more. Therefore, a cosmetic carrying capacity of the cosmetic applicator is greatly improved to make a user dip the cosmetic from the cosmetic bottle less frequently and achieve convenience in use and a higher makeup efficiency.

Abstract: A bristle is provided. A first end of the bristle serves as a free end, and a second end of the bristle serves as a root. A cross section of the bristle is in a closed shape defined by at least two lines. Each of the lines is straight or curved. The bristle is twisted along a circumferential direction of its own axis. A mascara brush includes a core and at least one bristle. A root of the bristle is provided on the core, and a free end of the bristle is provided away from the core. A single row of bristles are spaced apart along an axis of the core, or multiple rows of bristles are spaced apart along the axis of the core and arranged radially along a circumferential direction of the core.

Abstract: A mascara brush having a tornado-shaped bristle includes a bristle and a core. A root of the bristle is provided on the core, and a free end of the bristle is provided away from the core. There is at least one bristle. A centerline of the bristle intersects with an axis of the core in a non-perpendicular manner. By providing an included angle between the centerline of the bristle and the axis of the core, the bristle is inserted between eyelashes more easily. As the bristle is not perpendicular to the axis of the core, a cross section of the whole mascara brush is reduced. While the length of the bristle remains the same, the opening of a mascara bottle is reduced. The new mascara brush has the advantages of better application effect, more compact structure and better ease of eyelash combing.

Abstract: A cosmetic applicator is formed from two lateral branches that extend from a hub. The lateral branches arc away from one another and then toward one another as they extend in the distal direction with each branch forming a concave inside edge. The concave edges of the branches define a cavity. Distal ends of the branches are unconnected, allowing the branches to flex independently of one another. A membrane extends from the hub and is at least partially positioned in the cavity between the branches. The hub and branches are formed from a first material with a first hardness. The membrane is formed from a second material with a hardness different from the first material.

Abstract: An ice processing system may include a plurality of electrodes configured to create a time-varying electromagnetic field in a cavity, and a controller configured to oscillate a density of the electromagnetic field at a frequency which depends on the temperature of an object in the cavity. The frequency is selected based on a temperature of the object to establish and maintain a resonance condition of dipoles in ice crystals present in the object, such that the electromagnetic field tends to selectively heat ice substantially without heating liquid-phase water.

The actions further include updating the user interface to present at least some of the additional phrases with programmatic controls that assign one or more of the additional phrase as distribution criteria for digital components of the digital component provider in response to activation of the programmatic controls.

Abstract: A report generated from analysis of a software sample is obtained and parsed. A root node of a causality tree is determined based on source-target relationships and a primary malware instance indicated in the report. Actions, behaviors, and additional malware instances are identified based on the report. Additional relationships among the data which are not explicitly represented are extracted from further parsing and processing of the report by tracing the relationships in the report data starting from the data of the entity represented by the root node, with child nodes added for processes and files discovered from the tracing. For each entity for which a node is added to the causality tree, counts of the related behaviors and actions are determined and associated with the node along with the corresponding details. A GUI depiction of the resulting causality tree is generated and displayed for visualizing and navigating the causality tree.
