Copy number variants (CNVs) are strongly implicated in neurological and psychiatric disorders and brain cancer, yet the process by which replication stress generates CNVs—and why some recur while others remain rare—remains poorly understood.

Very little progress has been made during the last decade toward a theoretical understanding of the physical properties of matter in the solid state. The reasons for this stagnation are very clearly presented in a recent paper by A. Smekal.(1) According to Smekal, the properties of solids can be arranged in two large groups as follows.

Categories of Cutaneous Mosaicism
In this overview, the following 12 different categories of cutaneous mosaicism are considered: (1) Discrimination between monoallelic and biallelic mosaicism in autosomal dominant traits; (2) Segmental versus disseminated mosaicism in autosomal dominant ...

This paper considers the problem of placing mosaic\ud tiles on a surface to produce a surface mosaic. We assume\ud that the user specifies a mesh model, the size of the\ud tiles and the amount of grout, and optionally, a few control\ud vectors at key locations on the surface indicating the\ud preferred tile orientation at these points.

Maternal XX/X chromosome mosaicism in donor oocyte in vitro fertilization (IVF)
Objective: To evaluate if the degree of maternal X chromosome mosaicism is correlated to the pregnancy loss rate in donor oocyte IVF in women with a Turner syndrome mosaic (TS-Mosaic) diagnosis. Design: Prospective trial. Patients and methods: Women with

Data shift is a gap between data distribution used for training and data distribution encountered in the real-world. Data augmentations help narrow the gap by generating new data samples, increasing data variability, and data space coverage. We present a new data augmentation: Unproportional mosaicing (Unprop). Our augmentation randomly splits an image
