description: The hundreds of cichlid species forming part of the radiation of East African Lakes show a remarkable diversity of phenotypic and ecological adaptation. Despite this, recent studies highlighted that genetic diversity within the radiation is among the lowest ever observed in vertebrates. Such a high phenotype/genotype diversity ratio makes cichlids a promising system to investigate the role of genetics and, for the first time at a species level, epigenetics in the context of adaptation and convergent evolution. Yet, the molecular mechanisms and, in particular, any epigenetic aspects underlying such phenotypic diversity and speciation success remain largely unknown. Here, I focus on whole-genome DNA methylation (methylome), a heritable and dynamic epigenetic mark that has been reported to be responsible for rapid and transmissible changes in phenotype in plants and mammals. In light with phenotypic plasticity related to diet adaptation, I hypothesise that the liver methylome may affect liver function and thus be related to diet. I thus performed sequencing of liver tissues of different cichlid species presenting distinct eco-morphological and trophic adaptation from both Lake Malawi and crater lake Massoko, Tanzania. The main results reveal striking differences in methylome at conserved underlying DNA sequences – some variation shared in cichlids of both lakes. Furthermore, I observe an enrichment for methylome variation in transposable elements (TE) and promoter regions. Remarkably, most of the variation (ca 80%) common to fishes from both lakes are located in TEs and is, in part, correlated with differential expression levels at some key metabolic and developmental genes in liver. This suggests a possible conserved role of TE-related methylome in the adaptation of liver function. Furthermore, I generated inter-species hybrids to investigate the inheritance of DNAme variation in cichlids. The liver methylome of F1 hybrids, although mostly resembling parental methylomes, exhibited some level of divergence, suggesting unique DNAme patterns in hybrid offspring and possible transgressive segregation. I conclude there might be a conserved crosstalk between the local environment and methylome in different natural populations of cichlids. The results presented in this thesis postulate an important role of natural DNA methylation variation in promoting adaptive phenotypic diversification in divergent habitats during the early stages of speciation.

description: We present a two-layer accretion disc model developed to simultaneously fit optical long baseline visibilities and spectral energy distributions of T Tauri accretion discs. Our model includes viscous heating and absorption of stellar radiation. It analytically expresses the vertical structure of the disc using a two-layer approach: the outer layer is heated by the star and by the inner layer, and the inner layer by visous dissipation and by the outer layer. We compare three prescriptions for the flaring of the irradiated surface, and conclude that a smooth profile with r ~ r^1/8->1/7 has predictions close to those of comparable numerical models. The observables (spectra, images and visibilities) are numerically determined. We study the influence of disc parameters on the structure and observables. Then we apply it to three stars observed in IR interferometry. For T Tau and SU Aur we find a model fit consistent with both visibilities and spectrum but we could not in the case of T Tau North, which might come from caveats in the flux correction from the close South companion. We find that even a single interferometric measurement at one wavelength can bring a very strong constraint on disc models. We predict that future massive interferometric observations will provide a breakthrough in the understanding of accretion disc physics.

description: We report here a giant $\left|χ_{baa}^{2}\right|=$780 pm/V second harmonic and $\left|χ_{aaaa}^{3}\right|=$1.4$\times$10$^{-17}$ m$^{2}$/V$^{2}$ third harmonic signal from single atomic sheet of buckled hexagonal GaAs. We demonstrate this through the solution of an ab-initio real-time Bethe-Salpeter equation by including the electron-hole screened-exchange self-energy. The coupling between time-dependent external electric field and correlated electrons is treated within the modern theory of polarization. The result of our calculation envisage monolayer GaAs to be a prominent member in the material library of non-linear signal generations.

description: The standard model for radio supernovae considers that the observed synchrotron radio emission arises from the high-energy shell that results from the strong interaction between the expanding supernova ejecta and the circumstellar medium. This emission is considered to be only partially absorbed by ionized thermal electrons in the circumstellar wind of the progenitor star. Based on a study of the radio light curves of the type II supernova SN1993J, we present evidence of synchrotron self-absorption. Our modeling of the radio light curves requires a large initial magnetic field, of about 30 Gauss, and the existence of an (initially) highly-relativistic population of electrons. We also show that while at early epochs the dominant absorption mechanism is external absorption by thermal electrons, at late epochs and long wavelengths the dominant absorption mechanism is synchrotron self-absorption. Consequently, the spectral turnover takes place at much shorter wavelengths than expected in the standard model, and at long wavelengths (greater than about 90cm at current epochs) the flux predictions depart substantially from those of the standard model.

description: Climate change and urbanization are increasing the risks associated with extreme heat, threatening human lives and well-being. However, limited prior exposure to extreme heat events is resulting in underappreciation and unpreparedness in many localities. Using hazard mitigation plans as a proxy, we assess the preparedness of different localities in Virginia for the risks posed by extreme heat. Our plan evaluation involves measuring the quality of 20 Planning Districts’ hazard mitigation plans in Virginia in terms of extreme heat diagnosis, analysis, planning and implementation, based on a set of criteria derived from previous studies and mandates required by FEMA. Our results reveal that while the risk of extreme heat in Virginia is increasing, this risk is not recognized as a high or immediate priority in many plans. Our analysis further demonstrates that the insufficient recognition of the risk associated with extreme heat led to the absence of proper heat mitigation strategies. The findings of this study highlight the necessity for more in-depth evaluations of hazard mitigation plans regarding extreme heat and the importance of including various overlooked measures in those plans, which could ultimately assist local jurisdictions in developing efficient heat risk reduction policies and moving toward resiliency.

description: We study the spin polarizations of both tau leptons in the decay b -> s tau+ tau-. In addition to the polarization asymmetries involving a single tau, we construct asymmetries for the case where both polarizations are simultaneously measured. We also study forward-backward asymmetries with polarized tau's. We find that a large number of asymmetries are predicted to be large, >~ 10%. This permits the measurement of all Wilson coefficients and the b-quark mass, thus allowing the standard model (SM) to be exhaustively tested. Furthermore, there are many unique signals for the presence of new physics. For example, asymmetries involving triple-product correlations are predicted to be tiny within the SM, O(10^{-2}). Their observation would be a clear signal of new physics.

description: We develop a quantum many-body theory of the Bose-Hubbard model based on the canonical quantization of the action derived from a Gutzwiller mean-field ansatz. Our theory is a systematic generalization of the Bogoliubov theory of weakly-interacting gases. The control parameter of the theory, defined as the zero point fluctuations on top of the Gutzwiller mean-field state, remains small in all regimes. The approach provides accurate results throughout the whole phase diagram, from the weakly to the strongly interacting superfluid and into the Mott insulating phase. As specific examples of application, we study the two-point correlation functions, the superfluid stiffness, the density fluctuations, for which quantitative agreement with available quantum Monte Carlo data is found. In particular, the two different universality classes of the superfluid-insulator quantum phase transition at integer and non-integer filling are recovered.

description: Transition metal catalysed C-H activation is a highly desirable strategy for the functionalization of organic molecules. It allows for a rapid generation of structurally complex products from simple precursors in an atom- and step-economic fashion. Iridium catalysed borylation of arenes is a powerful yet mild C-H activation transformation which yields synthetically useful boronate esters. Interestingly the selectivity of this reaction is largely based upon steric considerations. As a result, the process is highly effective for 1,3-disubstituted arenes but produces a statistical mixture of regioisomers for 1,2-disubstituted arenes. Non-covalent interactions are a very powerful tool, utilized beautifully in enzymatic catalysis to address issues of regio- and enantioselectivity. In sharp contrast however their utilisation in directing the same aspects of selectivity in transition metal catalysed transformations is rather underexplored. This doctoral thesis aims to explore the use of non-covalent interactions in this setting. Chapter 2 of this thesis discloses the evaluation of an anionic sulfonated bipyridine ligand, previously reported within the group, to act as a hydrogen-bond acceptor to interact with aromatic amides. This interaction was shown to be crucial for the development of a meta-selective borylation process with excellent levels of meta-selectivity seen on three distinct substrate classes: benzylamine, phenethylamine and phenylpropylamine derived amides. Chapter 3 explores the further development of the sulfonated bipyridine scaffold with the introduction of a chiral counter-cation. The approach allows for the formation of a chiral environment around the metal centre via a chiral counter-ion directed catalysis and was demonstrated on the example of desymmetrising iridium catalysed borylation of arenes. The design and development of a modified version of the sulfonated bipyridine ligand bearing a cinchona alkaloid derived counter-cation is presented. The novel ligand design has enabled the borylation of meta-substituted benzhydrylamides and phosphinamides giving enantioenriched products in great enantioselectivities and good yields. When utilised for borylation of ortho-substituted benzhydrylamides, the process was demonstrated not only to be enantioselective, but also regioselective for the meta-position. The reaction represented a rare case of utilising a chiral cation to direct enantioselectivity of a transition metal catalysed process, enabling a challenging enantioselective remote C-H activation to yield highly versatile boronate ester products.

The 21 cm Forest: Radio Absorption Spectra as Probes of Minihalos Before Reionization

Subjects: subject: Astrophysics (astro-ph)

description: We study the absorption along lines of sight toward high-z radio sources caused by the 21 cm transition of neutral hydrogen in the intergalactic medium (IGM) before reionization. Using semi-analytic methods, we compute the number density of observable features caused by both ``minihalos'' (bound objects that are unable to cool efficiently because of their small virial temperatures) and protogalactic disks. We show that both sets of features should be observable by the next generation of low-frequency radio telescopes, including the Low Frequency Array and the Square Kilometer Array, provided that sufficiently bright background sources exist. The statistics of minihalo absorption features seen along lines of sight to radio-loud quasars offer a way to measure the evolution of the radiation background and the IGM temperature with cosmic time. Intersections with disks are much less common, but also cause much deeper absorption features that would be visible in the spectra of both radio-loud quasars and gamma-ray bursts (GRBs). The absorption feature caused by HI in the host galaxy of a GRB should be observable, offering a route to determine spectroscopically the burst redshift.

Approach to Solving Quasiclassical Equations with Gauge Invariance

Year: 2019
Subjects: subject: Superconductivity (cond-mat.supr-con)
subject: FOS: Physical sciences

description: Quasiclassical equations with manifest gauge invariance are discussed in the context of unconventional singlet superconducting states in the static limit. Deviations of the quasiclassical propagator from its equilibrium solutions in the presence of magnetic fields and Hall terms are analysed in terms of a small parameter and a formulation developed to first order in small. A modified quasiclassical propagator is defined to this order that is a solution of a new gauge-invariant Eilenberger-like equation with a normalisation condition. A Ricatti parametrisation with manifest gauge invariance is proposed. This theory is directly applicable to homogenous d-wave order parameters in the presence of magnetic fields, such as in high-temperature superconductors.

description: We study an SOS model whose dynamics is inspired by recent studies of the synchronization transition in coupled map lattices (CML). The synchronization of CML is thus related with a depinning of interface from a binding wall. Critical behaviour of our SOS model depends on a specific form of binding (i.e., transition rates of the dynamics). For an exponentially decaying binding the depinning belongs to the directed percolation universality class. Other types of depinning, including the one with a line of critical points, are observed for a power-law binding.

description: This thesis explores how the Romans constructed their past and what it looked like by using its material remains in the period from the first century BC to the second century AD. Using a combination of texts, objects, and images, I explore themes relevant to the modern fields of heritage studies and museology and push their histories back to the ancient world. After examining how one might define what we mean by ‘the past’ and its relationship to material things in my introduction, my first chapter provides a literature review of previous studies of similar topics and introduces some of the many examples we have in ancient texts and images of Roman engagements with things and buildings made by previous generations. In my second chapter I address architectural fragments and ruins and how they were used by authors and artists to create meaning about time and space. My third chapter deals with architectural reconstruction and how its documentation has affected how people imagine past versions of Rome to have looked and my final chapter focuses on Roman funerals and the objects used in them as situations where past and present versions of Rome were brought into play. Broadly, this thesis historicises how material remains have been used to construct and curate Roman history and in its conclusion offers suggestions for how modern curations might engage with the Romans’ own constructions of their past.

description: The aim of this study is to increase our understanding of the specification and estimation of Boro rice (principal rice) supply response in Bangladesh as well as to provide instrument for agriculture planting decision and price policy by using econometric tools-cointegration and error correction model with careful attention to time series data to avoid spurious regression of traditional econometric analysis Econometric model has been specified on the basis of theoretical arguments. This study also provides a theoretical argument that leads to formulate an empirical model from various aspects with price and non-price variables. The study is designed to identify statistically the acreage responses of Boro rice in Bangladesh. Time series data have been used in the analysis for the period 1972-73 to 2003-04. Econometric and statistical techniques are applied to estimate the supply responses of Boro rice at the national level. Long-run own price acreage elasticities for Boro is 0.95 (near to unitary elastic) respectively. Short-run own price acreage elasticities for Boro rice shows inelastic rang 0.21. Limitations and inadequate irrigation facilities at private level, distribution and availability of fertilizer in time are always problems in Bangladesh. Moreover, a main input like capital is insufficient in the short-run. These constraints helped to dampen the price elasticity of Boro rice supply in the short-run.The result suggests that farmers in Bangladesh are responsive to price incentives for Boro rice. If government promotes expanding expenditure at public and private level to build irrigation infrastructure and certified seeds it would give positive results on Boro supply in the country. Finally, if Bangladesh government follows a price stabilization policy it will reduce price risk and produce positive impact on Boro rice as well as overall crop supply situation in agriculture sector.

Antibunching has been observed in the fluorescence light under both continuous and pulsed excitation. Our source delivers 2*10^4 single-photon pulses per second at an excitation repetition rate of 10 MHz. The number of two-photon pulses is reduced by a factor of five compared to strongly attenuated coherent sources.

description: Receiver protectors (RPs) shield sensitive electronics from high-power incoming signals that might damage them. Typical RP schemes range from simple fusing and PIN diodes, to superconducting circuits and plasma cells - each having a variety of drawbacks ranging from unacceptable system downtime and self-destruction to significant insertion losses and power consumption. Here, we theoretically propose and experimentally demonstrate a unique self-shielding RP based on a coupled-resonator-microwave-waveguide (CRMW) with a topological defect being inductively coupled to a diode. This RP utilizes a charge-conjugation (C) symmetric resonant defect mode that is robust against disorder and demonstrates high transmittance at low incident powers. When incident power exceeds a critical value, a self-induced resonant trapping effect occurs leading to a dramatic suppression of transmittance and a simultaneous increase of the reflectance close to unity. The proposed RP device is self-protected from overheating and electrical breakdown and can be utilized in radars, reflection altimeters, and a broad range of communication systems.

description: We present new near-infrared (JHK) bispectrum speckle-interferometry monitoring of the carbon star IRC+10216 obtained between 1999 and 2001 with the SAO 6m telescope. The J-, H-, and K-band resolutions are 50mas, 56mas, and 73mas, resp. The total sequence of K-band observations covers now 8 epochs from 1995 to 2001 and shows the dynamic evolution of the inner dust shell. The present observations show that the appearance of the dust shell has considerably changed compared to the epochs of 1995 to 1998. Four main components within a 0.2" radius can be identified in the K-band images. The apparent separation of the two initially brightest components A and B increased from ~191mas in 1995 to ~351mas in 2001. Simultaneously, component B has been fading and almost disappeared in 2000 whereas the initially faint components C and D became brighter (relative to peak intensity). These changes can be related to changes of the optical depth caused, e.g., by mass-loss variations or new dust condensation in the wind. Our 2D radiative transfer model suggests that the observed relative motion of A and B is not consistent with the known terminal wind velocity of 15 km/s. The apparent motion with a deprojected velocity of 19 km/s on average and of recently 27 km/s appears to be caused by adisplacement of the dust density peak due to dust evaporation in the optically thicker and hotter environment. Our monitoring, covering more than 3 pulsation periods, shows that the structural variations are not related to the stellar pulsation cycle in a simple way. This is consistent with the predictions of hydrodynamical models that enhanced dust formation takes place on a timescale of several pulsation periods. The timescale of the fading of component B can well be explained by the formation of new dust in the circumstellar envelope.

description: The purpose of this study is to evaluate the progress and regional variations in agricultural development. The secondary data were used and collected for the years 1980-81 to 2002-03 from the `Statistical Yearbooks of Bangladesh', `Yearbook of Agricultural Statistics' and census of different years. The study was conducted during the period from September 2006 to February 2008. Methodological framework of ranking, indexing, principal component analysis and composite index of development were formulated. An empirical analysis was done for twelve mutually exclusive agro-ecological zones by assigning various indicators of agricultural development. Level of development of these zones was classified according to low, medium and high developed regions using hierarchical positions of the regions. The remarkable progress of rural literacy rate, ratio of agricultural workers to population, number of farmer's co-operative societies and per capita regional domestic agricultural products in two decades was observed in different regions. Wide disparities in the level of agricultural development had been observed across the regions. The hierarchical position of the regions reveals that `Old Himalayan Piedmont Plain and Tista Floodplain', 'Karatoya Floodplain and Atrai Basin', 'Brahmaputra- Jamuna Floodplain', `Middle Meghna River Floodplain' and 'Chittaging Coastal Plain and St. Martin's Coral Island' were the high developed regions in Bangladesh. For minimizing disparities among the agro-ecological zones and to promote balanced agricultural development, the resources should be distributed on the basis of equity. efficiency, productivity and sustainability.

Triple gauge couplings in polarised e-e+ -> W-W+ and their measurement using optimal observables

description: The sensitivity of optimal integrated observables to electroweak triple gauge couplings is investigated for the process e-e+ -> W-W+ -> 4 fermions at future linear colliders. By a suitable reparameterisation of the couplings we achieve that all 28 coupling parameters have uncorrelated statistical errors and are naturally normalised for this process. Discrete symmetry properties simplify the analysis and allow checks on the stability of numerical results. We investigate the sensitivity to the couplings of the normalised event distribution and the additional constraints that can be obtained from the total rate. Particular emphasis is put on the gain in sensitivity one can achieve with longitudinal beam polarisation. We also point out questions that may best be settled with transversely polarised beams. In particular we find that with purely longitudinal polarisation one linear combination of coupling parameters is hardly measurable by means of the normalised event distribution.

description: An intrinsic tunnel junction was made using two Bi-2212 single crystal whiskers. The two whiskers with a cross-angle were overlaid at their c-planes and connected by annealing. The angular dependence of the critical current density along the c-axis is of the d-wave symmetry. However, the angular dependence is much stronger than that of the conventional d-wave. Furthermore, the current vs. voltage characteristics of the cross-whiskers junctions show a multiple-branch structure at any cross-angle, indicating the formation of the intrinsic Josephson junction array.

description: With the development of Shrimp industry, different catagories of stakeholders of coastal communitities are involved in production, procesing and marketing of shrimp. The present study made an attempt to determine the gender role and empowerment of stakehoders involved in shrimp industry. Considering the different activities performed and the section of communities people (stakeholder) engaged in shrimp industry was divided into I 1 sub-sectors. Data were collected from 220 stakeholders including both men and women involved in different sectors of shrimp industry. The men and women were involved in shrimp farm activities as shrimp seed collectors, shrimp farm labourers and workers in procesing plant and depot. Moreover, male participation and involvement in different works of shrimp industry are dominant compared to women. In addition, men earned more compared to women where both men and women labourers were employed. On the other hand, women participation and involvement were gretear both in reproductive activities and homebased income generating activities. Considering all the activities of shrimp farm, per day time budget for women was sufficicently higher (15.45 hours) compared to men stakeholders (11.30 hours). Time allocation for income generating activities has also being incresed for women stakeholders after development of shrimp industry. Again, women stakeholders participated in activities of decision making process of family affairs and management of household assets indicating women empowerment.

description: The H$α$ velocity fields of a sample of six luminous blue compact galaxies (BCGs) and two companions have been obtained by observations with a scanning Fabry-Perot interferometer. The Fabry-Perot images, velocity fields and rotations curves have been presented in a previous paper (Paper I). In general, the velocity fields are irregular and often contain secondary dynamical components, but display overall rotation. The two companions have more regular velocity fields and rotation curves. In this article we analyse the velocity fields and dynamics together with the morphology of the studied BCGs, and present detailed mass models. In addition, we model the stellar mass content by means of multicolour surface photometry and spectral evolutionary synthesis analysis. By comparison of the masses of stars and those derived from the rotation curve, we show that about half of the galaxies cannot be supported by rotation alone. The morphology and dynamics of the BCGs suggest that the starburst activity in these galaxies are most likely triggered by mergers involving gas-rich dwarf galaxies and/or massive gas clouds.
