AbstractFlow cytometric analysis and sorting of plant mitotic chromosomes has been mastered by only a few laboratories worldwide. Yet, it has been contributing significantly to progress in plant genetics, including the production of genome assemblies and the cloning of important genes. The dissection of complex genomes by flow sorting into the individual chromosomes that represent small parts of the genome reduces DNA sample complexity and streamlines projects relying on molecular and genomic techniques. Whereas flow cytometric analysis, that is, chromosome classification according to fluorescence and light scatter properties, is an integral part of any chromosome sorting project, it has rarely been used on its own due to lower resolution and sensitivity as compared to other cytogenetic methods. To perform chromosome analysis and sorting, commercially available electrostatic droplet sorters are suitable. However, in order to resolve and purify chromosomes of interest the instrument must offer high resolution of optical signals as well as stability during long runs. The challenge is thus not the instrumentation, but the adequate sample preparation. The sample must be a suspension of intact mitotic metaphase chromosomes and the protocol, which includes the induction of cell cycle synchrony, accumulation of dividing cells at metaphase, and release of undamaged chromosomes, is time consuming and laborious and needs to be performed very carefully. Moreover, in addition to fluorescent staining chromosomal DNA, the protocol may include specific labelling of DNA repeats to facilitate discrimination of particular chromosomes. This review introduces the applications of chromosome sorting in plants, and discusses in detail sample preparation, chromosome analysis and sorting to achieve the highest purity in flow‐sorted fractions, and their suitability for downstream applications.

Abstract Fish stocking is one of the most widespread and frequent management strategies in freshwater systems. However, the contribution of stocked fish to the population is seldom investigated, and hence the effectiveness of this strategy is virtually unknown for many populations. Understanding the contribution of stocked fish into the population is crucial because it allows the disentanglement of the confounding effects generated by allochthonous individuals into the estimation of survival and growth rates of the population. To discriminate between the allochthonous and autochthonous individuals in a population, the shape of sagittae otoliths from pikeperch (Sander lucioperca) where compared. Results indicated significant differences among stocked and non-stocked fish, with the former having smaller and wider sagittae otoliths than the latter. Our results suggest that this technique can be used to discriminate the natal origin of fish in a much faster and cheaper way than commonly used techniques.

We consider a stationary viscous incompressible flow around a translating and rotating body. Optimal rates of decay are derived for the velocity and its gradient, on the basis of a representation formula involving a fundamental solution constructed by R.B. Guenther and E.A. Thomann [The fundamental solution of the linearized Navier–Stokes equations for spinning bodies in three spatial dimensions – time dependent case, J. Math. Fluid Mech. 8 (2006) 77–98], for a linearized system.

This article is devoted to the derivation and analysis of a system of partial differential equations modeling a diffuse interface flow of two Newtonian incompressible magnetic fluids. The system consists of the incompressible Navier-Stokes equations coupled with an evolutionary equation for the magnetization vector and the Cahn-Hilliard equations. We show global in time existence of weak solutions to the system using the time discretization method.

Abstract2‐Bromo‐1‐(3,3‐dinitroazetidin‐1‐yl)ethan‐1‐one (RRx‐001) is a hypoxic cell chemotherapeutics with already demonstrated synergism in combined chemo‐radiation therapy. The interaction of the compound with secondary low‐energy electrons formed in large amounts during the physico‐chemical phase of the irradiation may lead to these synergistic effects. The present study focuses on the first step of RRx‐001 interaction with low‐energy electrons in which a transient anion is formed and fragmented. Combination of two experiments allows us to disentangle the decay of the RRx‐001 anion on different timescales. Sole presence of the electron initiates rapid dissociation of NO2 and HNO2 neutrals while NO2− and Br− anions are produced both directly and via intermediate complexes. Based on our quantum chemical calculations, we propose that bidirectional state switching between π*(NO2) and σ*(C−Br) states explains the experimental spectra. The fast dynamics monitored will impact the condensed phase chemistry of the anion as well.

The core idea for this Special Issue is to reflect upon the dynamics of participation both by individuals and by groups acting in solidarity with migrants in different contexts at the individual, local and transnational levels. Using the concept of “solidarities” to address the relation between persons who have experienced migration and persons who have not, and between people and institutions, enables research to escape the “us vs. them” dichotomy, extending the debate on deservingness to society as a whole. Moreover, with the development of crossborder volunteering and the diffusion of multi-scalar partnerships between subnational governments and civil society organisations, solidarities are rescaled, and encompass new forms beyond national welfare mechanisms. Bringing together a rich collection of empirical cases that ranges from the reception of the Rohingya refugees in the Cox Bazar region of Bangladesh to border crossings along the Balkan route, from disaster solidarity in the Hanshin area in Japan to Ukrainian refugee reception in Italy, we explore acts of solidarity in different contexts as a way to try and make sense of when solidarity towards migrants is a political act, when it is about providing basic provisions subcontracted by the state to local or non-governmental actors, and when it is an act of defiance against the state.

We build a dynamic duopoly model that accounts for the empirical observation of monopoly persistence in the long run. More specifically, we analyze the conditions under which it is optimal for the market leader in an initially duopoly setup to undertake pre-emptive R&D investment ("strategic predation") that eventually leads to the exit of the follower firm. The follower is assumed to benefit from the innovative activities of the leader through R&D spillovers. The novel feature of our approach is that we introduce an explicit dynamic model and contrast it with its static counterpart. Contrary to the predictions of the static model, strategic predation that leads to the persistence of monopoly is in general the optimal strategy to pursue in a dynamic framework when spillovers are not large.

The ALICE Collaboration has measured the energy dependence of exclusive photoproduction of J/psi vector mesons off proton targets in ultra-peripheral p-Pb collisions at a centre-of-mass energy per nucleon pair =5.02 TeV. The e+e- and mu+mu- decay channels are used to measure the cross section as a function of the rapidity of the J/psi in the range -2.5

We present the first measurement of event-by-event fluctuations in the kaon sector in Pb - Pb collisions at root S-NN = 2.76 TeV with the ALICE detector at the LHC. The robust fluctuation correlator nu(dyn) is used to evaluate the magnitude of fluctuations of the relative yields of neutral and charged kaons, as well as the relative yields of charged kaons, as a function of collision centrality and selected kinematic ranges. While the correlator nu(dyn) [K+,K-] exhibits a scaling approximately in inverse proportion of the charged particle multiplicity, nu(dyn)[K-S(0),K-+/-] features a significant deviation from such scaling. Within uncertainties, the value of nu(dyn) [K-S(0), K-+/-] is independent of the selected transverse momentum interval, while it exhibits a pseudorapidity dependence. The results are compared with HIJING, AMPT and EPOS-LHC predictions, and are further discussed in the context of the possible production of disoriented chiral condensates in central Pb - Pb collisions.
