Abstract: An example of a biotin-streptavidin cleavage composition includes a formamide reagent and a salt buffer. The formamide reagent is present in the biotin-streptavidin cleavage composition in an amount ranging from about 10% to about 50%, based on a total volume of the biotin-streptavidin cleavage composition. The salt buffer makes up the balance of the biotin-streptavidin cleavage composition. In some examples, the biotin-streptavidin cleavage composition is used to cleave library fragments from a solid support. In other examples, other mechanisms are used to cleave library fragments from a solid support.

Abstract: A method that may be computer implemented converts a tensor value from a first format to a second format and trains a neural network. The method determines a maximum exponent code in the first format and subtracts a first bias to obtain the highest needed exponent. It determines a second bias from the highest available code (HAC) in the second format and the HNE, and converts the tensor value from the first format to the second format by using the second bias instead of the first bias. The method uses the second format to train the neural network. The method may round the mantissa of the tensor value in the first format to obtain a rounded mantissa of the tensor value for the second format.

Abstract: Intravascular delivery system is designed for a safe and efficient access to secondary and tertiary vascular structures, such as the branches of the coronary sinus, to enhance the delivery and deployment of various catheters, such as, for example, pacemaker electrical leads. The over-the-wire system features a straight, or alternatively shaped, micro-catheter distal tip of an inner catheter that seamlessly cooperates with a peel-away reinforced outer catheter. The inner catheter and the peel-away reinforced outer catheter are advanced in their engaged mode of operation towards (or beyond) the target site. Subsequently, the inner and outer catheters are disengaged, and the inner catheter is removed from the outer catheter. A pacemaker lead may be advanced over the wire inside the outer catheter to the target site for deployment. Subsequently, the outer catheter is easily split and may be rapidly removed from the blood vessel.

A planning component within a vehicle may determine a non-preferred surface associated with a type of non-preferred area of an environment along a route of a vehicle, determine a preferred surface associated with a preferred area of the environment, determine an adjusted non-preferred surface by removing an overlapping area of the non-preferred surface that overlaps the preferred surface and determine a cost associated with a vehicle position based at least on the preferred surface and the adjusted non-preferred surface. The planning component may then determine a control trajectory for the autonomous vehicle based at least in part on the cost associated with the vehicle position.
