Abstract:
AbstractIt is well known that rather generalmutation-recombination models can be solved algorithmically (though not in closed form) by means of Haldane linearization. The price to be paid is that one has to work with a multiple tensor product of the state space one started from.Here, we present a relevant subclass of such models, in continuous time, with independent mutation events at the sites, and crossover events between them. It admits a closed solution of the corresponding differential equation on the basis of the original state space, and also closed expressions for the linkage disequilibria, derived by means of Möbius inversion. As an extra benefit, the approach can be extended to a model with selection of additive type across sites. We also derive a necessary and sufficient criterion for the mean fitness to be a Lyapunov function and determine the asymptotic behaviour of the solutions.

Abstract:
AbstractThe problem of epitaxial graphene formed on a semiconductor substrate is considered in the context of the extended Hubbard and Holstein–Hubbard models for electron–electron and electron–phonon interactions. The Haldane–Anderson model is chosen for the density of states of the substrate. Three regions of the phase diagram, specifically, spin- and charge-density waves and a spin- and charge-homogeneous paramagnetic state are considered. For a number of special cases used as examples, the similarities and differences of the electron states of graphene on semiconductor and metal substrates are demonstrated. It is shown that the main difference arises, if the Dirac point of graphene lies within the band gap of the semiconductor. Numerical estimations are performed for a SiC substrate.

Abstract:

 The paper empiricialy tests the use of various stability factors as early warning signals that can effectively predict the failure in Islamic banking institutions. These early warning signals enable the regulatory and supervisory authorities to take timely corrective action to safeguard the interest of fund providers such as depositors, investment account holders, creditors as well as other stakeholders. Using a 10-year panel data of 65 Islamic banks from 13 banking systems in the Middle East, North Africa, Asia and Europe, this study uses six stability indicators of CAMELS supervisory framework in a logistic model to see their effecitveness in predicting distress in Islamic banks. The model is then extended with the alternative capital are leverage ratios as well as macroeconomic variables in order to see whether simple leverage ratio offers better estimation results than the complex, risk weighted measures as debated by (Haldane, 2012).

Abstract:
In this article, we contemplate the dynamics of a three-tier system of nutrient, phytoplankton, and zooplankton with a gestation delay of discrete type and a distributed delay in nutrient recycling. Phytoplankton secretion-mediated alteration in the grazing pattern of zooplankton is encapsulated by a Monod–Haldane functional response. We carry out global sensitivity analysis for identifying the crucial model parameters having a significant impact on zooplankton density. The system potentially exhibits bistable configurations under identical ecological conditions by allowing different bifurcation scenarios, including multiple saddle-node and transcritical bifurcations with varying input rates of nutrients and inhibitory effects of phytoplankton against zooplankton. We observe that the gestation delay in zooplankton is responsible for the emergence of noxious bloom events. Interestingly, when the delay parameter crosses a threshold, the system experiences chaotic disorder, which prognosticates the onset of irregular bloom. Furthermore, by adding Gaussian white noise, we have extended the deterministic model to its stochastic counterpart. We found that white noise appears to regulate the survival and extinction of interacting populations. Comprehensive numerical simulations are consistent with mathematical results prognosticated by linear analysis.

Abstract:
In this paper, a comparison is provided between liquid-liquid and liquid-solid partitioning systems applied to the removal of high concentrations of 4-nitrophenol. The target compound is a typical representative of substituted phenols found in many industrial effluents while the biomass was a mixed culture operating as a conventional Sequencing Batch Reactor and acclimatized to 4-nitrophenol as the sole carbon source. Both two-phase systems showed enhanced performance relative to the conventional single phase bioreactor and may be suitable for industrial application. The best results were obtained with the polymer Hytrel™ which is characterized by higher partition capability in comparison to the immiscible liquid solvent (2-undecanone) and to the polymer Tone™. A model of the two systems was formulated and applied to evaluate the relative magnitudes of the reaction, mass transfer and diffusion characteristic times. Kinetic parameters for the Haldane equation, diffusivity and mass transfer coefficients have been evaluated by data fitting of batch tests for liquid-liquid and liquid-solid two phase systems. Finally, preliminary results showed the feasibility of polymer regeneration to facilitate polymer reuse by an extended contact time with the biomass.

Abstract:
Abstract The Drosophila melanogaster mutation Hmr rescues inviable hybrid sons from the cross of D. melanogaster females to males of its sibling species D. mauritiana, D. simulans, and D. sechellia. We have extended previous observations that hybrid daughters from this cross are poorly viable at high temperatures and have shown that this female lethality is suppressed by Hmr and the rescue mutations In(1)AB and D. simulans Lhr. Deficiencies defined here as Hmr− also suppressed lethality, demonstrating that reducing Hmr+ activity can rescue otherwise inviable hybrids. An Hmr+ duplication had the opposite effect of reducing the viability of female and sibling X-male hybrid progeny. Similar dose-dependent viability effects of Hmr were observed in the reciprocal cross of D. simulans females to D. melanogaster males. Finally, Lhr and Hmr+ were shown to have mutually antagonistic effects on hybrid viability. These data suggest a model where the interaction of sibling species Lhr+ and D. melanogaster Hmr+ causes lethality in both sexes of species hybrids and in both directions of crossing. Our results further suggest that a twofold difference in Hmr+ dosage accounts in part for the differential viability of male and female hybrid progeny, but also that additional, unidentified genes must be invoked to account for the invariant lethality of hybrid sons of D. melanogaster mothers. Implications of our findings for understanding Haldane's rule—the observation that hybrid breakdown is often specific to the heterogametic sex—are also discussed.

Abstract:
Abstract The seminal Haldane model brings up a paradigm beyond the quantum Hall effect to look for a plethora of topological phases in the honeycomb and other lattices. Here we dwell into this model considering a full parameter space in the presence of spin-orbit interaction as well as Zeeman field such that the flavour of Kane-Mele model is invoked. Adopting this extended Haldane model as an example, we elucidate, in a transparent manner, a number of topological features in a pedagogical manner. First, we describe various first order topological insulator phases and their characterizations while explaining various anomalous quantum Hall effects and quantum spin Hall effects in the extended Haldane model. Second, we demonstrate the concepts of higher order topological insulator phases along with the topological invariants in the anisotropic limit of the extended Haldane model. At the end, we discuss various open issues involving emergent or extended symmetries that might lead to a broader understanding of various topological phases and the associated criteria behind their emergence.

Abstract:
Abstract The analysis of fuel rod behavior has become increasingly important and reliable assessment of temperature distribution is vital. Gap conductance is a key parameter to calculate the heat transfer between fuel pellet and cladding, then fuel temperature and thermo-mechanical of fuel rods will be influenced. Gas conductance often plays the most important role comparing convective heat transfer, thermal radiation and solid contact conductance in fuel rod analysis. A new gas conductance model has been proposed, considering the effects of mixture gaseous component, the temperature discontinuity on the surfaces of pellet and cladding, and the roughness of solid surface, since the irregularity will become significant when the gap is closed at the extended burn-up. Moreover, the model has been calibrated with Modified Pulse Design (MPD) and Modified Longitudinal Design (MLD) experiment gas conductance data performed by John. E. Garnier and Stefan. Begej, and shown a good prediction accuracy at various experiment conditions. Furthermore, the model has been successfully implemented in fuel rod performance analysis code JASMINE to improving the temperature distribution prediction. Based on the comparison of code prediction of centerline temperature with HALDEN in-core irradiation tests data, the results show that the new gas conductance model has a decent suitability to JASMINE.
