Abstract: An example optical metasurface, an example illumination system, an example optical imaging sensor, and an example method of manufacturing an optical metasurface configured to compensate for birefringent effects, are provided. The example optical metasurface includes a plurality of asymmetric nanostructures having a cross-section defined at least by a first dimension and a second dimension. Each asymmetric nanostructure is positioned to receive incident light at a nanostructure location. The first dimension and the second dimension are defined based on an angle of incidence of the incident light at the nanostructure location, and a phase retardation value associated with the nanostructure location. The first dimension and the second dimension of the asymmetric nanostructure are further defined to counteract a birefringent property at the angle of incidence.

Abstract: An image sensor includes a pixel array and an image sensor objective optical element. The element is formed by a lenslet array. Each lenslet in the array directs incoming radiation onto a different specific pixel or sub-array of pixels in the pixel array. The lenslets in the array are shaped such that fields of view of next-but-one neighboring ones of the lenslets (i.e., two lenslets spaced from each other by another lenslet) do not overlap until a certain object distance away from the lenslet array.

Abstract: Compositions and methods for the identification, prognosis, classification, treatment, and diagnosis of leukemia or a genetic predisposition to leukemia are provided. The present invention is based on the discovery of various genomic abnormalities of the IKZF1 gene which are shown herein to be associated with acute lymphoblastic leukemia (ALL), more particularly, associated with BCR-ABL1 positive ALL and/or shown to be associated with chronic myeloid leukemia (CML), more particularly, associated with blast crisis chronic myeloid leukemia (BC-CML) and/or the likelihood of progression into blastic transformation of CML. These various genomic abnormalities of the IKZF1 gene can further be used as prognostic markers to identify a subgroup of ALL having very poor outcomes.

Abstract: Compositions and methods for the identification, prognosis, classification, diagnosis, and treatment of leukemia or a genetic predisposition to leukemia are provided. The present invention is based on the discovery of a novel intragenic deletion in the v-ets erythroblastosis virus E26 oncogene homolog (ERG) allele which is shown herein to be associated with a novel subtype of B-progenitor acute lymphoblastic leukemia (ALL). In one embodiment, the intragenic deletion in ERG results in the expression of C-terminal domain deletion forms of the ERG polypeptide which lacks the DNA-binding PNT domain and CAE domain of the ERG polypeptide and have dominant negative ERG activity. In other embodiments, the intragenic deletions results in a loss of expression of the native ERG polypeptide.

Abstract: A post attachment device for connecting a helmet to a head and neck support. The device includes a post anchor having a base, a button, a resilient member, a post, a retainer and a catch having a slot with a larger first section connected by a channel to a smaller second section. The button is positioned in an indention in the base with the resilient member positioned therebetween. The post extends through the button, the base and the helmet. The retainer is secured on the post adjacent the inner surface of the helmet. To secure the post attachment device, the catch is orientated over the post. The button is then depressed into the base while the catch is moved backwards to move the post into the second section of the slot.

Abstract: The present invention is a composition that includes granular-grade polytetrafluoroethylene and a plurality of microspheres, where the plurality of microspheres have an average specific gravity less than about 0.9 grams per cubic centimeter.

Abstract: Members of the InK4 (Inhibitors of CDK4) family inhibit the activities of specific cyclin D-dependent kinases (CDK4 and/or CDK6), thereby arresting cell cycle progression in G1 phase and preventing chromosomal DNA replication. Disclosed herein are novel mammalian InK4 family members, having apparent molecular masses of 18,000 and 19,000 daltons, designated "InK4c-p18" and "InK4d-p19," respectively, or simply "p18" and "p19." In particular, the invention provides p19 genes and proteins isolated from murine or human cells and p18 genes and proteins from murine cells. When constitutively expressed in cells, p19 inhibits cyclin D-dependent kinase activity in vivo and induces G1 phase arrest.
