description: By using optimal mass transport theory, we provide a direct proof to the sharp L p L^p -log-Sobolev inequality ( p ≥ 1 ) (p\geq 1) involving a log-concave homogeneous weight on an open convex cone E ⊆ R n E\subseteq \mathbb R^n . The perk of this proof is that it allows to characterize the extremal functions realizing the equality cases in the L p L^p -log-Sobolev inequality. The characterization of the equality cases is new for p ≥ n p\geq n even in the unweighted setting and E = R n E=\mathbb R^n . As an application, we provide a sharp weighted hypercontractivity estimate for the Hopf-Lax semigroup related to the Hamilton-Jacobi equation, characterizing also the equality cases.

description: This paper uses a deterministic Cobb- Douglas production function to estimate efficiency of pond fish farms from Mymensingh, Bangladesh. We consider estimation of farm specific technical. allocative and economic efficiency using average and frontier production function which accommodates endogenous inputs because exogenous variables are beyond the control of the farms. Farm specific technical and allocative efficiency are estimated separately for both credit and contact farmers. Empirical results show that the mean level of technical efficiency for the credit and contact farmers are J8.84,~ and 98.79 respectively. Both categories of fish farms are technically. allocatively and economically efficient.
The Role of Arabidopsis thaliana Annexins 1, 2 and 4 in Extracellular ATP Signalling

description: Extracellular ATP (eATP) is an important signalling molecule in animals but its importance is less understood in plants. Accumulation of eATP in plants occurs in response to biotic and abiotic stresses. eATP causes downstream responses such as increase in cytosolic free calcium ([Ca$^{2+}$]$_{cyt}$), reactive oxygen species (ROS), nitric oxide (NO) and phosphatidic acid (PA). The identification of $\it{Arabidopsis}$ $\it{thaliana}$ AtDORN1 (Does Not Respond to Nucleotides) as the first higher plant purinoreceptor has confirmed eATP in plant signalling systems. AtDORN1 is a plasma membrane receptor kinase that appears to command the eATP-induced transient increase in [Ca$^{2+}$]$_{cyt}$ and directs the translational response to wounding. The identity of the plasma membrane Ca$^{2+}$-permeable channels involved in eATP-induced [Ca$^{2+}$]$_{cyt}$ increases remain unknown. Patch clamp electrophysiology has shown that a plasma membrane Ca$^{2+}$ influx conductance lies downstream of the AtRBOHC NADPH oxidase in the response to eATP. As $\it{Arabidopsis}$ $\it{thaliana}$ ANNEXIN 1 (AtANN1) underpins ROS-activated plasma membrane Ca$^{2+}$ influx conductance, it has been considered here as operating downstream of AtDORN1 in the eATP-induced increase in [Ca$^{2+}$]$_{cyt}$. In this thesis, the role of AtANN1, AtANN2 and AtANN4 in eATP signalling was tested in $\it{A.}$ $\it{thaliana}$. Using (apo)aequorin, AtANN1 and ANNEXIN 2 (AtANN2) have been found to be involved in the root′s [Ca$^{2+}$]$_{cyt}$ response to both eATP and eADP whereas ANNEXIN 4 (AtANN4) might be acting as a negative regulator of AtANN1 (Chapters 3 and 4). Application of Gd$^{3+}$ as a plasma membrane Ca$^{2+}$ channel blocker indicated the possibility of the release of Ca$^{2+}$ from intracellular stores (Chapters 3 and 4). AtANN1 is confirmed to be downstream of the AtDORN1 receptor and also possibly downstream of AtRBOH NADPH Oxidase based on [Ca$^{2+}$]$_{cyt}$ measurement and ROS assays (Chapter 3). Loss${-}$of${-}$function mutants of AtANN1, AtANN2 and AtANN4 altered the eATP${-}$induced gene expression of $\it{AtACS6}$ but not $\it{AtWRKY40}$ demonstrating a possible link between eATP signalling and hormone responses in plants (Chapters 3 and 4). Unlike AtANN1 and AtANN4, fewer studies regarding the involvement of AtANN2 in salinity stress and biotic stress were reported. In Chapter 5, results suggest that AtANN2 might not be part of the components mediating salinity stress and biotic stress in plants.

description: We propose an all-loop expression for scattering amplitudes in planar N=4 super Yang-Mills theory in multi-Regge kinematics valid for all multiplicities, all helicity configurations and arbitrary logarithmic accuracy. Our expression is arrived at from comparing explicit perturbative results with general expectations from the integrable structure of a closely related collinear limit. A crucial ingredient of the analysis is an all-order extension for the central emission vertex that we recently computed at next-to-leading logarithmic accuracy. As an application, we use our all-order formula to prove that all amplitudes in this theory in multi-Regge kinematics are single-valued multiple polylogarithms of uniform transcendental weight.

description: This study is an attempt to generate some micro level information in respect of pattern of consumption of selected food items and the related food consumption parameters. The results showed that rural consumers consumed more rice and non-food items. Per capita consumption of food in general increased substantially with rise in per capita income. The difference between the poor and the rich in terms of nutrition intake was wider in urban than in rural area. The findings also revealed that the quantities consumed or expenditure on food-rain, potato and pulses did not increase much with rising income in both the areas. On the other hand. chances in income were found to have more impact on consumption of other commodities.

description: Managerial practices such as strategic planning, audit, and performance appraisal pervade global governance regimes, including the regime of international criminal justice (ICJ). The mainstream view is that such practices are objective tools which optimise institutional performance and thereby assist them in attaining their goals. Against this view, I offer an alternative understanding of managerial practices. Viewing international criminal justice as a technocratic imaginary, and defining managerial practices as tools of power/knowledge, I explore the discursive effects of management upon the contemporary project of ICJ. I problematize the assumptions inherent in the mainstream approach to managerial practices, relying on critical international law and critical management scholarship to provide a comprehensive sociology and history of management. Employing a genealogical method, I trace the historical journey of managerial practices from the steel factories of the American Midwest to the structures of the United Nations after decolonization. This genealogy reveals the political significance of management as a set of tools deployed to reinforce extant distributions of institutional power. At the International Criminal Court (ICC), I trace the expansion of managerial practices and find them to have certain reality- and identity-making effects on the organisation and its professional staff. Managerial practices produce the court as an efficient, modern institution, reinforcing the image of ICJ as the optimal allocation of institutional resources by experts. Such practices also produce the identity of the ICC lawyer as an efficient cog in the ICJ machine. Collectively, managerial practices enact a discursive closure around an institutional and expert-driven ICJ project. That discursive closure is illustrated further in two detailed studies: the ICC Presidency and the reorganisation of the Registry. Demonstrating the mechanics of managerial knowledge, the thesis reveals how international criminal justice is governed.

description: In this work we review the derivation of Dirac and Weinberg equations based on a ``principle of indistinguishability'' for the (j,0) and (0,j) irreducible representations (irreps) of the Homogeneous Lorentz Group (HLG). We generalize this principle and explore its consequences for other irreps containing spin >= 1. We rederive Ahluwalia-Kirchbach equation using this principle and conclude that it yields O(p^{2j}) equations of motion for any representation containing spin j and lower spins. We also use the obtained generators of the HLG for a given representation to explore the possibility of the existence of first order equations for that representation. We show that, except for j=1/2, there exists no Dirac-like equation for the (j,0)\oplus (0,j) representation nor for the (1/2,1/2) representation. We rederive Kemmer-Duffin-Petieau (KDP) equation for the (1,0)\oplus (1/2,1/2)\oplus(0,1) representation by this method and show that the (1,1/2)\oplus (1/2,1) representation satisfies a Dirac-like equation which describes a multiplet of j=3/2 and j=1/2 with masses m and m/2} respectively.

description: A wide range of methods exist for interpolation between spatially distributed points drawn from a single population. Yet often multiple datasets are available with differing distribution, character and reliability. A simple scheme is introduced to allow the fusion of multiple datasets. Each dataset is assigned an a priori spatial influence zone around each point and a relative weight based on its physical character. The composite result at a specific location is a weighted combination of the spatial terms for all the available data points that make a significant contribution. The combination of multiple datasets is illustrated with the construction of a unified Moho surface in part of southern Australia from results exploiting a variety of different styles of analysis.

description: Most quantum computer realizations require the ability to apply local fields and tune the couplings between qubits, in order to realize single bit and two bit gates which are necessary for universal quantum computation. We present a scheme to remove the necessity of switching the couplings between qubits for two bit gates, which are more costly in many cases. Our strategy is to compute in and out of carefully designed interaction free subspaces analogous to decoherence free subspaces, which allows us to effectively turn off and turn on the interactions between the encoded qubits. We give two examples to show how universal quantum computation is realized in our scheme with local manipulations to physical qubits only, for both diagonal and off diagonal interactions.

description: We investigate, using simulated galaxy catalogues, the completeness of searches for massive clusters of galaxies in redshift surveys or imaging surveys with photometric redshift estimates, i.e. what fraction of clusters (M>10^14/h Msun) are found in such surveys. We demonstrate that the matched filter method provides an efficient and reliable means of identifying massive clusters even when the redshift estimates are crude. In true redshift surveys the method works extremely well. We demonstrate that it is possible to construct catalogues with high completeness, low contamination and both varying little with redshift.

description: Nectar spurs (tubular outgrowths of a floral organ which contain or give the appearance of containing nectar) are hypothesized to be a ‘key innovation’ which can lead to rapid speciation within a lineage, because they are involved in pollinator specificity. However, given that there are no conventional model plant species which possess a nectar spur, much is still unknown about the development and morphogenesis of spurs. This project aimed to determine the molecular and morphological processes underpinning nectar spur development. The well-known study system Antirrhinum majus (snapdragon), which possesses only a nectar pouch, called a gibba, was compared to the common toadflax Linaria vulgaris, a related species within the Antirrhineae which possesses a spur. The comparison between a species with a gibba and a species which possesses a spur allows insights into nectar spur development. A morphological framework was produced and used to inform a comparative transcriptome based on A. majus and L. vulgaris at three key developmental stages. This experiment provides a global view of the genes involved in nectar spur and gibba development and suggests new candidate genes for nectar spur outgrowth. The control of variation in nectar spur length at both a morphological and molecular level was also investigated, focusing on Linaria becerrae and Linaria clementei, sister species which have extremely long and short spurs respectively. A morphological characterisation (recording cell number and cell length across a range of developmental stages) was performed to determine whether the difference is due to cell expansion or cell division. We found that primarily cell number and therefore cell division drives an increase in spur length. This contrasts with previous studies in Aquilegia which have found that variation of nectar spur length is due to directed cell expansion (anisotropy) over a longer timeframe. A genetic approach to understanding genetic basis of spur length was pursued, by crossing L. becerrae and L. clementei, and producing an F2 and backcrosses. This work lays a groundwork for future studies and suggests that the genetic basis of spur length in Linaria may be complex. The morphological and genetic work to investigate control of spur length was complemented by a candidate gene approach. Candidate genes from previous work and suggested by the transcriptome were isolated in L. becerrae and L. clementei and expression in the ventral and dorsal petals tested via sqPCR.

description: We simulate the spectral behaviour of the non-transient gamma-ray binaries using archival observations as a reference. With this we test the CTA capability to measure the sources' spectral parameters and detect variability on various time scales. We review the known properties of gamma-ray binaries and the theoretical models that have been used to describe their spectral and timing characteristics. We show that CTA is capable of studying these sources on time scales comparable to their characteristic variability time scales. For most of the binaries, the unprecedented sensitivity of CTA will allow the spectral evolution to be studied on a time scale as short as 30 min. This will enable a direct comparison of the TeV and lower energy (radio to GeV) properties of these sources from simultaneous observations. We also review the source-specific questions that can be addressed with such high-accuracy CTA measurements.

description: The local cohomology of an extended BRST differential which includes global N=1 supersymmetry and Poincare transformations is completely and explicitly computed in four-dimensional supersymmetric gauge theories with super-Yang-Mills multiplets, chiral matter multiplets and linear multiplets containing 2-form gauge potentials. In particular we determine to first order all N=1 supersymmetric and Poincare invariant consistent deformations of these theories that preserve the N=1 supersymmetry algebra on-shell modulo gauge transformations, and all Poincare invariant candidate gauge and supersymmetry anomalies. When the Yang-Mills gauge group is semisimple and no linear multiplets are present, we find that all such deformations can be constructed from standard superspace integrals and preserve the supersymmetry transformations in a formulation with auxiliary fields, and the candidate anomalies are exhausted by supersymmetric generalizations of the well-known chiral anomalies. In the general case there are additional deformations and candidate anomalies which are relevant especially to the deformation of free theories and the general classification of interaction terms in supersymmetric field theories.

description: Given a complex vector subspace V V of C n \mathbb {C}^n , the dimension of the amoeba of V ∩ ( C ∗ ) n V \cap (\mathbb {C}^*)^n depends only on the matroid that V V defines on the ground set { 1 , … , n } \{1,\ldots ,n\} . Here we prove that this dimension is given by the minimum of a certain function over all partitions of the ground set, as previously conjectured by Rau. We also prove that this formula can be evaluated in polynomial time.

description: This dissertation consists of three related essays that contribute to the literature on the behavior of institutional investors and particularly endowments - distinctive because of their long horizon. The vast majority of endowments delegate the management of their assets to external managers. My first essay provides evidence that decisions taken by endowments about their external investment manager appointments (and terminations) are influenced by the behavior of their peers. This analysis exploits a novel hand-collected dataset on U.S. university endowments and their external investment manager appointments across all the main asset classes for each year over 1978-2008. The study documents that endowments are more likely to appoint the same external manager if their peers do so, are more active in hiring and firing managers when their peers are more active and respond faster to hiring and firing decisions by their peers in respect of a given external manager. The second essay examines the network connections between endowments and PE managers. Buyout (BO) and Venture Capital (VC) investment networks are examined separately. Using data from 1988 to 2008, I identify the characteristics of the centrally located endowments and managers in the network. While VC networks were more developed than their BO counterparts at the beginning of the sample period, both networks grew denser over time in terms of number of players and connections. The identity of their key institutions (central endowments and managers) stayed the same throughout the period examined. Centrally located managers have better investment returns and win new endowment mandates in subsequent periods. Personal connections between individuals working at endowments and BO firms also play an important role in manager selection by endowments. The third essay examines the long-term evolution of the investment strategy of U.S. university endowments, using a unique long-term dataset on characteristics and asset allocations from 1900 to 2016 of twelve important endowments. The analysis documents their early adoption of equity investing in the 1930s and their more recent shift into alternative assets from the 1980s. The essay then considers whether endowments famed for their long horizon exploit this advantage to invest countercyclically during periods of market turbulence. I find that endowments do exhibit countercyclical behaviour, decreasing their allocation to risky assets during the run-up to a crisis and increasing it after the onset of a crisis.

description: We study the fingerprint of the Arnol'd diffusion in a quantum system of two coupled nonlinear oscillators with a two-frequency external force. In the classical description, this peculiar diffusion is due to the onset of a weak chaos in a narrow stochastic layer near the separatrix of the coupling resonance. We have found that global dependence of the quantum diffusion coefficient on model parameters mimics, to some extent, the classical data. However, the quantum diffusion happens to be slower that the classical one. Another result is the dynamical localization that leads to a saturation of the diffusion after some characteristic time. We show that this effect has the same nature as for the studied earlier dynamical localization in the presence of global chaos. The quantum Arnol'd diffusion represents a new type of quantum dynamics and can be observed, for example, in 2D semiconductor structures (quantum billiards) perturbed by time-periodic external fields.

description: The economic impact of tertiary education is important for regional development, and whilst participation rates have increased, it is unclear whether this has benefited regions equally. The paper analyses a panel of European regions to determine how the geography of tertiary education has evolved between 2002 and 2012. The results show a mixed picture. Overall, the system is characterized by path dependency, with the past being the best predictor of the future. There are some signs that the most lagging regions in 2002 are catching up, with some benefiting from recently opened institutions. Meanwhile, the very top-performing regions are breaking away from the rest, showing above-average growth, especially in the case capital regions. This work contributes to the ongoing research on the role of higher education in fostering regional economic development, and the emerging inequalities across European regions.

Rupestrella somalensis

description: Rupestrella somalensis (Verdcourt, 1963)
Type locality: Somalia, northern region, Mait-Erigavo Escarpment, 5,900 feet alt.
 Notes.—This species was originally classified with Granopupa. Based on the original description and figure, however, it clearly belongs to Rupestrella. As already mentioned by Verdcourt (1963) it appears to be affiliated with R. michaudi, based on the slender shell shape. Its geographical location is rather isolated. It extends the known distribution of the genus considerably southward.

description: The Chandra X-Ray Observatory (CXO), the x-ray component of NASA's Great Observatories, was launched on 1999, July 23 by the Space Shuttle Columbia. After satellite systems activation, the first x-rays focussed by the telescope were observed on 1999, August 12. Beginning with the initial observation it was clear that the telescope had survived the launch environment and was operating as expected. Despite an initial surprise due to the discovery that the telescope was far more efficient for concentrating CCD-damaging low-energy protons than had been anticipated, the observatory is performing well and is returning superb scientific data. Together with other space observatories, most notably XMM-Newton, it is clear that we have entered a new era of discovery in high-energy astrophysics.

Steady-state density functional theory for thermoelectric effects

description: The recently proposed density functional theory for steady-state transport (i-DFT) is extended to include temperature gradients between the leads. Within this framework, a general and exact expression is derived for the linear Seebeck coefficient which can be written as the sum of the Kohn-Sham coefficient and an exchange-correlation contribution. The formalism is applied to the single-impurity Anderson model for which approximate exchange-correlation functionals are suggested for temperatures both above and below the Kondo temperature. A certain structural property of the exchange-correlation potentials in the Coulomb blockade regime allows to recover an earlier result expressing the Seebeck coefficient in terms of quantities of equilibrium density functional theory. The numerical i-DFT results are compared to calculations with the numerical renormalization group over a wide range of temperatures finding a reasonable agreement while i-DFT comes at a much lower computational cost.

Stationary and Axisymmetric Perfect-Fluid Solutions with Conformal Motion

description: Stationary and axisymmetric perfect-fluid metrics are studied under the assumption of the existence of a conformal Killing vector field and in the general case of differential rotation. The possible Lie algebras for the conformal group and corresponding canonical line-elements are explicitly given. It turns out that only four different cases appear, the abelian and other three called I, II and III. We explicitly find all the solutions in the abelian and I cases. For the abelian case the general solution depends on an arbitrary function of a single variable and the perfect fluid satisfies the equation of state rho = p+const. This class of metrics is the one presented recently by one of us. The general solution for case I is a new Petrov type D metric, with the velocity vector outside the 2-space spanned by the two principal null directions and a barotropic equation of state rho +3p=0. For the cases II and III, the general solution has been found only under the further assumption of a natural separation of variables Ansatz. The conformal Killing vectors in the solutions that come out here are, in fact, homothetic. No barotropic equation of state exists in these metrics unless for a new Petrov type D solution belonging to case II and with rho +3p=0 which cannot be interpreted as an axially symmetric solution and such that the velocity vector points in the direction of one of the Killing vectors. This solution has the previously unknown curious property that both commuting Killing vectors are timelike everywhere.

More (or Less) Economic Limits of the Blockchain

subject: FOS: Computer and information sciences

description: This paper extends the blockchain sustainability framework of Budish (2018) to consider proof of stake (in addition to proof of work) consensus mechanisms and permissioned (where the number of nodes are fixed) networks. It is demonstrated that an economically sustainable network will involve the same cost regardless of whether it is proof of work or proof of stake although in the later the cost will take the form of illiquid financial resources. In addition, it is shown that regulating the number of nodes (as in a permissioned network) does not lead to additional cost savings that cannot otherwise be achieved via a setting of block rewards in a permissionless (i.e., free entry) network. This suggests that permissioned networks will not be able to economize on costs relative to permissionless networks.
