description: We investigate the low-temperature properties of the one-dimensional spin-1 Heisenberg model with geometric fluctuations induced by aperiodic but deterministic coupling distributions, involving two parameters. We focus on two aperiodic sequences, the Fibonacci sequence and the 6-3 sequence. Our goal is to understand how these geometric fluctuations modify the physics of the (gapped) Haldane phase, which corresponds to the ground state of the uniform spin-1 chain. We make use of different adaptations of the strong-disorder renormalization-group (SDRG) scheme of Ma, Dasgupta and Hu, widely employed in the study of random spin chains, supplemented by quantum Monte Carlo and density-matrix renormalization-group numerical calculations, to study the nature of the ground state as the coupling modulation is increased. We find no phase transition for the Fibonacci chain, while we show that the 6-3 chain exhibits a phase transition to a gapless, aperiodicity-dominated phase similar to the one found for the aperiodic spin-1/2 XXZ chain. Contrary to what is verified for random spin-1 chains, we show that different adaptations of the SDRG scheme may lead to different qualitative conclusions about the nature of the ground state in the presence of aperiodic coupling modulations.

description: Previous research has found a positive association between social class and mental health among university students. Various mediators of this association have been proposed. However, the extent to which students perceive these mediators as having an impact on their mental health has not been investigated. It is important to investigate this issue because students who do not perceive issues as having an impact on their mental health may not be motivated to address those issues. In the current study, 402 first-year undergraduate psychology students from a large Australian university indicated the extent to which 32 issues had a negative impact on their mental health over the past six months. Students rated lack of money, time management, coursework assessment items, lack of sleep, and course marks as having the largest impact on their mental health. Lack of money and time management mediated the positive association between subjective social status and mental health over (a) the past week and (b) the past month. Coursework assessment items and course marks mediated the positive association between subjective social status and satisfaction with the university experience. It is concluded that interventions should focus on these relatively high impact issues in order to address social class differences in students’ mental health and university satisfaction.
New N=1 dualities from orientifold transitions - Part II: String Theory

description: We present a string theoretical description, given in terms of branes and orientifolds wrapping vanishing cycles, of the dual pairs of gauge theories analyzed in 1210.7799. Based on the resulting construction we argue that the duality that we observe in field theory is inherited from S-duality of type IIB string theory. We analyze in detail the complex cone over the zeroth del Pezzo surface and discuss an infinite family of orbifolds of flat space. For the del Pezzo case we describe the system in terms of large volume objects, and show that in this language the duality can be understood from the strongly coupled behavior of the O7^+ plane, which we analyze using simple F-theory considerations. For all cases we also give a different argument based on the existence of appropriate torsional components of the 3-form flux lattice. Along the way we clarify some aspects of the description of orientifolds in the derived category of coherent sheaves, and in particular we discuss the important role played by exotic orientifolds - ordinary orientifolds composed with auto-equivalences of the category - when describing orientifolds of ordinary quiver gauge theories.

description: Motivated by the rich theory of harmonic maps from a 2-sphere, we study biharmonic maps from a 2-sphere in this paper. We first derive biharmonic equation for rotationally symmetric maps between rotationally symmetric 2-manifolds. We then apply the equation to obtain a classification of biharmonic maps in a family of rotationally symmetric maps between 2-spheres. We also find many examples of proper biharmonic maps defined locally on a 2-sphere. Our results seem to suggest that any biharmonic map $S^2\longrightarrow (N^n, h)$ be a weakly conformal immersion.

Redox chemistry and metal-insulator transitions intertwined in a nano-porous material

description: Metal organic frameworks are nano porous adsorbents of relevance to gas separation and catalysis, and O2 separation from air is essential to diverse industrial applications. A metal organic framework Fe2(DOBDC), also known as a MOF74, can selectively adsorb O2 in a manner that defies the classical picture: Adsorption sites either do or do not share electrons over a long range. This report proposes, and then justifies phenomenologically and computationally, a mechanism. Charge transfer mediated adsorption of an electron acceptor O2 in a quasi one dimensional (1D) electron donor semiconductor Fe2(DOBDC) drives and is driven by 1D metal insulator transitions that localize or delocalize the 1D electrons. This mechanism agrees with the empirical evidence, and predicts a class of nano porous semiconductors or metals and potential adsorbents and catalysts in which chemistry and metal insulator transitions intertwine.

description: We summarize the properties of the new periodic, small amplitude, variable stars recently discovered in the open cluster NGC 3766. They are located in the region of the Hertzsprung-Russell diagram between δ Sct and slowly pulsating B stars, a region where no sustained pulsation is predicted by standard models. The origin of their periodic variability is currently unknown. We also discuss how the Gaia mission, to be launched at the end of 2013, can contribute to our knowledge of those stars.

title: The expression, purification and characterization of recombinant human lung surfactant protein-B
Creators: name: Asrat, Tadiwos G.

Year: 2023

description: A way to produce surfactant protein B (SP-B) in the laboratory is highly sought both for basic research on SP-B, as well as for use as a component of surfactant for treatment of patients in respiratory distress. Herein, I hypothesize that SP-B can be expressed in bacteria in its functional form. In the long run, I also anticipate that recombinant SP-B could alleviate the financial burden incurred by the health care system during the treatment of neonatal respiratory distress syndrome patients. Moreover, I envisage, recombinant surfactant protein B variants with an improved capability to resist surfactant dysfunction. In the first part of the study, recombinant DNA technology was used to overexpress the near full-length human SP-B variant, Δ7NTΔM-SP-B- 6xHis, in BL21 Escherichia coli , strain C43 cells. The results show that recombinant surfactant protein B expresses as inclusion bodies but can be renatured carefully using immobilized metal ion affinity chromatography. Importantly, the thesis work has established a protocol for the production of recombinant surfactant protein B that is amenable to scale up. In the next part of the study, circular dichroism was used to assess the conformation of recombinant SP-B suspensions in different membrane mimetic environments. Likewise, dynamic light scattering was used to characterize sample homogeneity and aggregation propensity of the protein suspension in these conditions. It was found that dodecyl phosphocholine/sodium dodecyl sulfate binary micelles and methanol support native-like secondary structure of recombinant SP-B comparable to animal derived surfactant protein B. In the last portion of the study, the function of recombinant SP-B was tested in lipid environments using the Langmuir-Wilhelmey surface balance. The results indicate that recombinant SP-B possesses the necessary biophysical features to promote the large-scale organization of lipid monolayers that are thought to be critical to SP-B function. In conclusion this work supports the use of recombinant SP-B in a surfactant therapeutic as a potential future alternative to animal derived SP-B.

description: In this study, we examined the relationship between participating in FP and international co-authorship patterns by using a gravity model with proximity dimensions. Our estimates generally confirm the literature about the effect of various proximity types on scientific collaboration. We found that spatial proximity still matters for the cooperation between scientists, considering the progress in communication and transportation. Cognitive proximity appeared as the most influential factor in generating knowledge. Institutional proximity, represented by the similarity of language and being sibling countries, also affects the co-authorship tendencies. Nevertheless, our estimates on the impact of working together in FP projects on co-publication are not as expected. The results show a relationship between co-partnering in FP projects and co-publication behaviours. Yet, the effect is ambiguous and small. These results imply that further research is needed for the effect of international research programs on co-publishing. In addition to different proximity measures, we need meso- (such as regions) and micro-level (such as universities) analyses. Using InCites, which is based on Web of Science (WoS) data, is one of the limitations of our study since WoS coverage favours some research fields and languages. Also, we used aggregated data in this study, while scientific disciplines vary publication and collaboration behaviours. Further research is needed to deal with these limitations.

description: Estimating the number $n$ of unseen species from a $k-$sample displaying only $p\leq k$ distinct sampled species has received attention for long. It requires a model of species abundance together with a sampling model. We start with a discrete model of iid stochastic species abundances, each with Gibbs-Poisson distribution. A $k-$sample drawn from the $n-$species abundances vector is the one obtained while conditioning it on summing to $k$% . We discuss the sampling formulae (species occupancy distributions, frequency of frequencies) in this context. We then develop some aspects of the estimation of $n$ problem from the size $k$ of the sample and the observed value of $P_{n,k}$, the number of distinct sampled species. It is shown that it always makes sense to study these occupancy problems from a Gibbs-Poisson abundance model in the context of a population with infinitely many species. From this extension, a parameter $γ$ naturally appears, which is a measure of richness or diversity of species. We rederive the sampling formulae for a population with infinitely many species, together with the distribution of the number $P_{k}$ of distinct sampled species. We investigate the estimation of $γ$ problem from the sample size $k$ and the observed value of $P_{k}$. We then exhibit a large special class of Gibbs-Poisson distributions having the property that sampling from a discrete abundance model may equivalently be viewed as a sampling problem from a random partition of unity, now in the continuum. When $n$ is finite, this partition may be built upon normalizing $% n$ infinitely divisible iid positive random variables by its partial sum. It is shown that the sampling process in the continuum should generically be biased on the total length appearing in the latter normalization. A construction with size-biased sampling from the ranked normalized jumps of a subordinator is also supplied, would the problem under study present infinitely many species. We illustrate our point of view with many examples, some of which being new ones.

description: Finding a good compromise between the exploitation of known resources and the exploration of unknown, but potentially more profitable choices, is a general problem, which arises in many different scientific disciplines. We propose a stylized model for these exploration-exploitation situations, including population or economic growth, portfolio optimisation, evolutionary dynamics, or the problem of optimal pinning of vortices or dislocations in disordered materials. We find the exact growth rate of this model for tree-like geometries and prove the existence of an optimal migration rate in this case. Numerical simulations in the one-dimensional case confirm the generic existence of an optimum.

description: We consider Calabi-Yau threefolds $X$ over an algebraically closed field $k$ of characteristic $p>0$ that are not liftable to characteristic $0$ or liftable ones with $p=2$. It is unknown whether Kodaira vanishing holds for these varieties. In this paper, we give a lower bound of $h^1(X, L^{-1})=\dim_k H^1(X, L^{-1})$ if $L$ is an ample divisor with $H^1(X, L^{-1})\ne{0}$. Moreover, we show that a Kodaira type vanishing holds if $X$ is a Schröer variety or a Schoen variety, which extends the similar result given in my previous paper for the Hirokado variety. We show that such kind of vanishing holds for Calabi-Yau manifold whose Picard variety has no $p$-torsion. Also we show that a modified Raynaud-Mukai construction does not produce any counter-example to Kodaira vanishing.

description: In this study, we present a detailed, statistical analysis of black hole growth and the evolution of active galactic nuclei (AGN) using cosmological hydrodynamic simulations run down to $z=0$. The simulations self-consistently follow radiative cooling, star formation, metal enrichment, black hole growth and associated feedback processes from both supernovae typeII/Ia and AGN. We consider two simulation runs, one with a large co-moving volume of $(500\ \mathrm{Mpc})^3$ and one with a smaller volume of $(68\ \mathrm{Mpc})^3$ but with a by a factor of almost 20 higher mass resolution. Consistently with previous results, our simulations can widely match observed black hole properties of the local Universe. Furthermore, our simulations can successfully reproduce the evolution of the bolometric AGN luminosity function for both the low-luminosity and the high-luminosity end up to $z=3.0$. In addition, the smaller but higher resolution run is able to match the observational data of the low bolometric luminosity end at higher redshifts $z=3-4$. We also perform a direct comparison with the observed soft and hard X-ray luminosity functions of AGN, including an empirical correction for a torus-level obscuration, and find a similarly good agreement. These results nicely demonstrate that the observed "anti-hierarchical" trend in the AGN number density evolution (i.e. the number densities of luminous AGN peak at higher redshifts than those of faint AGN) is self-consistently predicted by our simulations. Implications of this downsizing behaviour on active black holes, their masses and Eddington-ratios are discussed. Overall, the downsizing behaviour in the AGN number density as a function of redshift can be mainly attributed to the evolution of the gas density in the resolved vicinity of a (massive) black hole.

description: The formulation of noncommutative quantum mechanics as a quantum system represented in the space of Hilbert-Schmidt operators is used to systematically derive, using the standard time slicing procedure, the path integral action for a particle moving in the noncommutative plane and in the presence of a magnetic field and an arbitrary potential. Using this action, the equation of motion and the ground state energy for the partcle are obtained explicitly. The Aharonov-Bohm phase is derived using a variety of methods and several dualities between this system and other commutative and noncommutative systems are demonstrated. Finally, the equivalence of the path integral formulation with the noncommutative Schrödinger equation is also established.

description: Explicit expressions for one-loop five supergraviton scattering amplitudes in both type II superstring theories are determined by making use of the pure spinor formalism. The type IIB amplitude can be expressed in terms of a doubling of ten-dimensional super Yang--Mills tree amplitude, while the type IIA amplitude has additional pieces that cannot be expressed in that manner. We evaluate the coefficients of terms in the analytic part of the low energy expansion of the amplitude, which correspond to a series of terms in an effective action of the schematic form D^{2k}R^5 for 0\le k \le 5 (where R is the Riemann curvature). Comparison with earlier analyses of the tree amplitudes and of the four-particle one-loop amplitude leads to an interesting extension of the action of SL(2,Z) S-duality on the moduli-dependent coefficients in the type IIB theory. We also investigate closed-string five-particle amplitudes that violate conservation of the U(1) R-symmetry charge -- processes that are forbidden in supergravity. The coefficients of their low energy expansion are shown to agree with S-duality systematics. A less detailed analysis is also given of the six-point function, resulting in the vanishing of the analytic parts of the R^6 and D^4 R^6 interactions in the ten-dimensional effective action, but not in lower dimensions.

description: In the light of recent results relating dynamic and thermodynamic stability of relativistic stars and black holes, we re-examine the relationship between "turning points"---i.e., extrema of thermodynamic variables along a one-parameter family of solutions---and instabilities. We give a proof of Sorkin's general result---showing the existence of a thermodynamic instability on one side of a turning point---that does not rely on heuristic arguments involving infinite dimensional manifold structure. We use the turning point results to prove the existence of a dynamic instability of black rings in 5 spacetime dimensions in the region where $c_J > 0$, in agreement with a result of Figueras, Murata, and Reall.

Stability of Z$_2$ topological order in the presence of vacancy-induced impurity band

description: Although topological insulators (TIs) are known to be robust against non-magnetic perturbations and exhibit edge or surface states as their distinct feature, experimentally it is known that vacancies often occur in these materials and impose strong perturbations. Here we investigate effects of vacancies on the stability of Z$_{2}$ topological order using the Kane-Mele (KM) model as a prototype of topological insulator. It is shown that even though a vacancy is not classified as a topological defect in KM model, it generally induces a pair of degenerate midgap states only in the TI phase. We show that these midgap states results from edge states that fit into vacancies and are characterized by the same Z$_{2}$ topological order. Furthermore, in the presence of many vacancies, an impurity band that is degenerate with edge states in energy is induced and mixes directly with edge states. However, the Z$_{2}$ topological order persists and edge states exist between the impurity band and perturbed bulk bands until a phase transition occurs when Dirac cones near Dirac points are depleted. Our analyses indicate that the same scenario holds for point vacancies or line of vacancies in 3D TIs as well.

Non-Equilibrium Dynamics of a Noisy Quantum Ising Chain: statistics of the work and prethermalization after a sudden quench of the transverse field
Creators: name: Marino, Jamir

description: We discuss the non-equilibrium dynamics of a Quantum Ising Chain (QIC) following a quantum quench of the transverse field and in the presence of a gaussian time dependent noise. We discuss the probability distribution of the work done on the system both for static and dynamic noise. While the effect of static noise is to smooth the low energy threshold of the statistic of the work, appearing for sudden quenches, a dynamical noise protocol affects also the spectral weight of such features. We also provide a detailed derivation of the kinetic equation for the Green's functions on the Keldysh contour and the time evolution of observables of physical interest, extending previously reported results (J. Marino, A. Silva, Phys. Rev. B 86, 060408 (2012)), and discussing the extension of the concept of prethermalization which can be used to study noisy quantum many body hamiltonians driven out-of-equilibrium.

description: A class of powerful $q$-ary linear polynomial codes originally proposed by Xing and Ling is deployed to construct good asymmetric quantum codes via the standard CSS construction. Our quantum codes are $q$-ary block codes that encode $k$ qudits of quantum information into $n$ qudits and correct up to $\flr{(d_{x}-1)/2}$ bit-flip errors and up to $\flr{(d_{z}-1)/2}$ phase-flip errors.. In many cases where the length $(q^{2}-q)/2 \leq n \leq (q^{2}+q)/2$ and the field size $q$ are fixed and for chosen values of $d_{x} \in \{2,3,4,5\}$ and $d_{z} \ge δ$, where $δ$ is the designed distance of the Xing-Ling (XL) codes, the derived pure $q$-ary asymmetric quantum CSS codes possess the best possible size given the current state of the art knowledge on the best classical linear block codes.

Theory of $U(1)$ gauged Q-balls revisited

description: In this paper, the main properties of (3+1)-dimensional $U(1)$ gauged Q-balls are examined. In particular, it is shown that the relation $\frac{dE}{dQ}=ω$ holds for such gauged Q-balls in the general case. As a consequence, it is shown that the well-known estimate for the maximal charge of stable gauged Q-balls was derived by means of an inconsistent procedure and can not be considered as correct. A simple method for obtaining the main characteristics of gauged Q-balls using only the nongauged background solution for the scalar field in the case, when the back-reaction of the gauge field on the scalar field is small and the linearized theory can be used, is proposed. The criteria of applicability of the linearized theory, which do not reduce to the demand of the smallness of the coupling constant, are established. Some interesting properties of gauged Q-balls, as well as the advantages of the proposed method, are demonstrated by the example of two models, admitting, in the linear approximation in the perturbations, exact analytic solutions for gauged Q-balls.

description: Black or Common Mulberry (Morus nigra) was introduced into Britain in the late sixteenth – early seventeenth centuries and has since had limited success as an ornamental and fruit-producing tree. Older specimens survive in a limited number of locations including at The Charterhouse in central London. Four of these trees were investigated with the aid of standard dendrochronological techniques, historic images, including an early postcard and a painting by Edward Ardizzone, and with the application of expert knowledge of the forms and ages of contemporary mulberry trees. Results included the creation of a new ring-width chronology (CH_Mulberry) and dating that suggests the two oldest trees may well have been planted to commemorate either Queen Victoria’s Golden (AD 1887) or Diamond Jubilee (AD 1897). The research represents a first known dendrochronological investigation of the species, highlighting issues associated with sampling “tortuous” growth forms and the poor visibility of sapwood rings, as well as the potential for the use of branch ring-widths to facilitate dendrochronological dating of fruit and other trees.

The small scale power asymmetry in the cosmic microwave background

description: We investigate the hemispherical power asymmetry in the cosmic microwave background on small angular scales. We find an anomalously high asymmetry in the multipole range l=601-2048, with a naive statistical significance of 6.5 sigma. However, we show that this extreme anomaly is simply a coincidence of three other effects, relativistic power modulation, edge effects from the mask applied, and inter-scale correlations. After correcting for all of these effects, the significance level drops to ~1 sigma, i.e., there is no anomalous intrinsic asymmetry in the small angular scales. Using this null result, we derive a constraint on a potential dipolar modulation amplitude, A(k)<0.0045 on the ~10 Mpc-scale, at 95% C.L. This new constraint must be satisfied by any theoretical model attempting to explain the hemispherical asymmetry at large angular scales.
