A simple and inexpensive mount for securely holding resin-embedded tissues for trimming prior to sectioning for light or electron microscopy is described. The unit is composed of a base plate from which a 12.7-mm drill chuck protrudes. A tissue block is clamped into a microtome chuck and that is mounted in the drill chuck. A standard dissecting microscope is placed over the unit and used to mag...

Two-step nonparametric estimators have become standard in empirical auctions. A drawback concerns boundary effects which cause inconsistencies near the endpoints of the support and bias in finite samples. To cope, sample trimming is typically used which leads to non-random data loss. Monte Carlo experiments show this leads to poor performance near the support boundaries and on the interior due ...

We demonstrate the trimming of silicon-on-insulator ring resonators with a cladding layer of polymerizable liquid crystal. An electric field is applied over the cladding layer to tune the resonance of the ring resonators, which is then fixed by UV illumination of the polymerizable liquid crystal. A range of 0.56 nm is obtained. We provide the material properties of the polymerizable liquid crys...

Trimmer Class STrimmer is the abstract base surface trimmer class. For every refinement level it defines the trimming of a surface along each control mesh dimension. This trimming is represent by a Start vector and an End vector, where the size of the vector is equal to the control mesh dimension. Each element in these vectors represent the number of control vertices that need to be trimmed fro...

acute leukemia which is the most common cancer in children is a heterogeneous group of clonal malignancies. the conversion of the leukemic cell lineage during the course of the disease or later is termed lineage switch. it has been rarely reported in the literature. in leukemia lineage switch, conversions from lymphoblastic leukemia to myeloid leukemia or vice versa are reported. herein, we rep...
