Crossover promotion and prevention
Biochemical Society Transactions, 2006 Homologous recombination is an important mechanism for the repair of double-strand breaks in DNA. One possible outcome of such repair is the reciprocal exchange or crossing over of DNA between chromosomes. Crossovers are beneficial during meiosis because, as well as generating genetic diversity, they promote proper chromosome segregation through the ...

High‐Entropy Magnetism of Murunskite
Advanced Functional Materials, EarlyView.The study of murunskite (K2FeCu3S4) reveals that its magnetic and orbital order emerges in a simple I4/mmm crystal structure with complete disorder in the transition metal positions. Mixed‐valence Fe ions randomly occupy 1/4 of the tetrahedral sites, with the remaining 3/4 being filled by non‐magnetic Cu+ ions.

FPGA Implementation of Crossover Module of Genetic Algorithm
Information, 2019 This paper proposes a hardware realization of the crossover module in the genetic algorithm for the travelling salesman problem (TSP). In order to enhance performance, we employ a combination of pipelining and parallelization with a genetic algorithm (GA)

Nature Communications, 2018 The discovery of iron-based superconductors (FeSCs), with the highest transition temperature (Tc) up to 55 K, has attracted worldwide research efforts over the past ten years. So far, all these FeSCs structurally adopt FeSe-type layers with a square iron

Advanced Functional Materials, EarlyView.This study highlights the impact of transition‐metal (TM) ions (Ni2⁺, Mn2⁺, Co2⁺) on the performance of lithium‐metal anode in localized high‐concentration electrolytes. Mn2⁺ and Co2⁺ destabilize SEI and CEI layers, causing capacity fade and overpotential, while Ni2⁺ shows minimal effects. These findings underscore the need for electrolyte optimization

Journal of the American Heart Association: Cardiovascular and Cerebrovascular Disease, 2019 Background Crossover dilutes treatment effect and reduces statistical power of intention‐to‐treat analysis. We examined incidence and impact on cardiac surgery randomized controlled trial (RCT) outcomes of crossover from experimental to control ...

Violation of the Widom scaling law for effective crossover exponents
, 2004 In this work we consider the universal crossover behavior of two non-equilibrium systems exhibiting a continuous phase transition. Focusing on the field driven crossover from mean-field to non-mean-field scaling behavior we show that the well-known Widom

Tackling Plant Meiosis: From Model Research to Crop Improvement
Frontiers in Plant Science, 2018 Genetic engineering and traditional plant breeding, which harnesses the natural genetic variation that arises during meiosis, will have key roles to improve crop varieties and thus deliver Food Security in the future. Meiosis, a specialized cell division

, 2009 We have considered the dislocation network model for the supersolid state in He-4 crystals. In difference with uniform 2D and 3D systems, the temperature of superfluid transition T_c in the network is much smaller than the degeneracy temperature T_d.
