Hidden breakpoints in genome alignments [PDF]
, 2012 During the course of evolution, an organism's genome can undergo changes that affect the large-scale structure of the genome. These changes include gene gain, loss, duplication, chromosome fusion, fission, and rearrangement.

Inversion breakpoints and the evolution of supergenes [PDF]
Molecular Ecology, 2021 AbstractThe coexistence of discrete morphs that differ in multiple traits is common within natural populations of many taxa. Such morphs are often associated with chromosomal inversions, presumably because the recombination suppressing effects of inversions help maintain alternate adaptive combinations of alleles across the multiple loci affecting ...

Clustering of Translocation Breakpoints [PDF]
Journal of the American Statistical Association, 2002 Translocation, a physical movement of genetic material from one chromosome to another, can result in the aberrant linkage of two cellular genes. This type of fusion may disrupt cellular function by producing novel, biologically active fused genes, or by triggering the activation of normally quiescent growth-associated genes.

Breakpoint medians and breakpoint phylogenies: A fixed-parameter approach [PDF]
Bioinformatics, 2002 Abstract With breakpoint distance, the genome rearrangement field delivered one of the currently most popular measures in phylogenetic studies for related species. Here, Breakpoint Median, which is NP-complete already for three given species (whose genomes are represented as signed orderings), is the core basic problem. For the important

SHORT-TERM TRAFFIC STATE ESTIMATION USING BREAKPOINT FLOW CALCULATION AND MACHINE LEARNING METHODS [PDF]
Scientific Journal of Silesian University of Technology. Series Transport, 2022 Estimation of the state of road traffic conditions is gaining increasing attention in recent intelligent transportation systems. Accurate and real-time estimation of traffic condition changes is critical in the management and control of road network ...

Statistics of Solar Wind Electron Breakpoint Energies Using Machine Learning Techniques [PDF]
, 2020 Solar wind electron velocity distributions at 1 au consist of a thermal "core" population and two suprathermal populations: "halo" and "strahl". The core and halo are quasi-isotropic, whereas the strahl typically travels radially outwards along the ...

Continuously Vegetation Greening over Inner Mongolia for the Past Three Decades
Remote Sensing, 2021 The warming climate has rapidly altered vegetation growth in drylands, and consequently, has put great pressure on sustainable livelihoods. Various datasets have been applied from local to global scale to study vegetation dynamics and there is a lack of ...

Experimental observation of the longitudinal plasma excitation in intrinsic Josephson junctions [PDF]
, 2008 We have investigated the current-voltage characteristics (IVCs) of intrinsic Josephson junctions (IJJs). Recently, it is predicted that the longitudinal plasma wave can be excited by the parametric resonance in IJJs.

Atmosphere, 2022 Structural changes, or changepoints, coinciding in multiple ice core records over the Greenland Ice Sheet (GrIS) may reflect a widespread response of the GrIS to atmospheric forcing.
