Abstract: The present disclosure relates to compositions and methods for reducing the concentration of extendable free and buried primers relative to amplification product in a sample. The disclosed methods and compositions can be used to reduce or eliminate index hopping in a next generation sequencing (NGS) platform.

Abstract: An apparatus can include a display, a facial interface, and a connector between the display and the facial interface. The facial interface can at least translate or rotate relative to the display via the connector.

Abstract: Described herein are compounds that are HSD17B13 inhibitors, methods of making such compounds, pharmaceutical compositions and medicaments comprising such compounds, and methods of using such compounds in the treatment of conditions, diseases, or disorders associated with HSD17B13 activity.

Abstract: A concentrated aqueous fertilizer which is readily water-soluble and a method of applying the solubilized dilute fertilizer to crops to enhance crop production are described. The dry fertilizer contains a contains nitrogen, phosphorus and potassium compounds, as well as a mixture of plant growth stimulators including at least one of each of growth promoters, vitamins, amino acids, carbohydrates/polysaccharides, and adjuvants.

Abstract: Methods are provided which minimize loss of an anti-icing/de-icing composition from a surface. This is accomplished by adhering the anti-icing/de-icing composition to a surface using a film-forming polymeric composition. Methods are also provided for preventing snow accumulation and/or ice formation on a surface, delaying ice and/or snow formation on a surface, extending the life of an anti-icing/de-icing composition on a surface, surface anti-icing, and surface de-icing. These methods include the application of a film-forming polymeric composition and the anti-icing/de-icing composition to the surface. Desirably, the anti-icing/de-icing composition is a reagent which reduces the freezing point of water.

Abstract: A light bar for mounting on an emergency vehicle to provide warning light signals. An elongate body portion has an elongate axis, the elongate body portion adapted to be mounted on the emergency vehicle so that the elongate axis traverses an axis coaxial with the direction of the travel of the emergency vehicle. At least three vertically spaced lighting layers are provided, each layer having at least one emergency light source, the emergency light sources on each layer cooperating to provide a transient high intensity warning light signal 360.degree. around the light bar. At least four linear rows of emergency light sources as viewed from the top of the light bar are also provided, the rows being substantially parallel to the elongate axis, each row having at least two emergency light sources, at least one row located in each of the layers and at least one layer having at least two rows, the emergency light sources in each row cooperate to provide a transient high intensity warning signal 360.degree.

Abstract: An emergency vehicle signal light adapted to be mounted on an emergency vehicle. A light source emits visible light for illuminating a reflector. A light pipe having one end associated with the light source has its second end associated with a diverter for diverting substantially all light transmitted by the light pipe toward the reflector. The reflector is adapted to reflect the diverted light transmitted by the light pipe for observance by an observer remote from the emergency vehicle. A motion driver may be provided for rotating or oscillating the reflector about the diverter. As a result, an observer is adapted to observe discrete flashes of light resulting from flashing, rotation or oscillation, each flash corresponding to diverted reflected light forming a beam. For oscillating or rotating modules, the beam traverses across the position of the observer in response to the rotational or oscillatory motion. Alternatively, such modules may be used as part of a light bar.

Abstract: A light bar comprises a plurality of modules and a control circuit including a power supply for selectively energizing each of the modules. Each module includes a strobe lamp having an anode and a cathode for energizing the strobe lamp and having a trigger for firing the strobe lamp, a reflector positioned adjacent the strobe lamp to reflect light emitted by the strobe lamp and a circuit including a capacitor connected to the anode and the cathode for energizing the strobe lamp. The circuit of the module connects the capacitor and the trigger to the control circuit. An incandescent lamp or a high intensity discharge lamp may be used separately or in combination with the strobe. Multicolor operation or the use of LCD panels as filters or reflectors is also contemplated.

Abstract: A hood for mounting a unidirectional lamp adjacent a window, such as a windshield, of an emergency vehicle and within a passenger compartment of the vehicle for directing light through the window. The lamp includes a housing having a forward portion defining an opening therein, a light source within the housing, and a lamp lens adjacent the forward portion of the housing and covering at least a portion of the opening for directing light from the light source through the opening. The hood comprising a hood body mountable adjacent the window having a rearward end defining a first open port dimensioned for receiving the forward portion of the housing, a forward end defining a second port opposite the first port, and a light pathway between the first and second ports for transmission of a beam of light from the light source through the body. A hood lens is within the body for optically altering the beam of light transmitted along the light pathway.
