When ionizing radiation strikes a cell it induces DNA double strand breaks (DSBs). Subsequently, some of the DSBs misrejoin and thus cause alterations in the size distribution of the DNA fragments. We derive a system of non-linear integro-differential equations describing the misrejoining interactions of five classes of DNA fragments, including rings and various types of linear fragments. The f...

This report details the implementation of a fragment extraction algorithm using an average case linear time tree kernel. Given a treebank, the algorithm extracts all fragments that occur at least twice, along with their frequency. Evaluation shows a -fold speedup over a quadratic fragment extraction implementation. Additionally, we add support for trees with discontinuous constituents.

Despite increasing knowledge about the effects of habitat loss on pollinators in natural landscapes, information is very limited regarding the underlying mechanisms of forest fragmentation affecting plant-pollinator interactions in such landscapes. Here, we used a network approach to describe the effects of forest fragmentation on the patterns of interactions involving the understory dominant p...

Malignant tumors shed DNA into the circulation. The transient half-life of circulating tumor DNA (ctDNA) may afford the opportunity to diagnose, monitor recurrence, and evaluate response to therapy solely through a non-invasive blood draw. However, detecting ctDNA against the normally occurring background of cell-free DNA derived from healthy cells has proven challenging, particularly in non-me...

Augmented reality (AR)-based surgical navigation may offer new possibilities for safe and accurate execution of complex osteotomies. In this study we investigated the feasibility navigating periacetabular osteotomy Ganz (PAO), known as one most orthopedic interventions, on two cadaveric pelves under realistic operating room conditions. Preoperative planning was conducted computed tomography (CT...

A microstructure consisting of ultrafine grained (UFG) ferrite with average grain size of ~ 0.7 µm and dispersed nano-sized carbides was produced by cold-rolling and tempering of the martensite starting microstructure in a low carbon steel. Subsequently, fine grained dual phase (DP) steel consisting of equiaxed ferrite grains with average size of ~ 5 µm and martensite islands with average size ...

The Horizon Fragments table lists the mineral and organic fragments that generally occur in the referenced horizon. If the Volume % is greater than zero (low=5, RV=10, high=15) in a row, the kind and size of fragment in that row exists everywhere this horizon and component occur in the map unit. If the Volume % includes zero (low=0, RV=5, high=10), the kind and size of fragment may exist in som...

Methods for automated detection of DNA restriction fragments resolved on agarose fingerprinting gels are described. We present a mathematical model for the location and shape of the restriction fragments as a function of fragment size, with model parameters determined empirically from marker lanes containing molecular size standards. Automated identification of restriction fragments involves se...

The ALADIN multifragmentation data for reaction Au+Au at several hundreds A.MEV show features characteristic of critical behavior, which are very well reproduced by a bond percolation model. This suggests, in the context of the lattice gas model, that fragments are formed at nearly normal nuclear densities and temperatures corresponding to the Kert\'{e}sz line. Calculations performed with a lat...
