description: We present a theoretical study of an exciton-polariton annular microcavity with an additional quasiperiodic structure along the ring which is implemented in the form of a bicosine dependence. We demonstrate that for a sufficiently strong quasiperiodic modulation, the microcavity features a sharp mobility edge separating a cluster of localized states from the rest of the spectrum consisting of states extended over the whole ring. Localized modes can be excited using a resonant pump whose topological charge determines the phase distribution of excited patterns. Repulsive polariton interactions make the resonance peaks distinctively asymmetric and enable the formation of multistable states which feature the attractor-like dynamical behavior \rev{and hysteresis}. We also demonstrate that the localized states can be realized in a biannular cavity that consists of two rings, each having periodic modulation, such that the periods of two modulations are different.

description: In economic theory the price movement at a general level is one of the essential issues that can significantly affect on economic flows. The aim of this paper is to show that there is a significant difference in the average price level in the countries of the region, where the value added tax rates are analysed at the same time. The subject of the paper is manifested by the reflection of the inflation rate and value added tax rate in seven countries in the region from 2008 to 2016. Selected countries are Serbia, Albania, Bosnia and Herzegovina, Croatia, Macedonia, Montenegro and Slovenia. Based on the graph, it was found that in the years when there was a growth of value added tax, the inflation rate was declined which means there is no positive impact of tax form on inflation ie. there is a reduction of the inflation rate. Also, bearing in mind fact that inflation rate is not primarily caused by the movement of value added tax rate, authors have focused on determining the difference between average inflation rate in observed countries. Using ANOVA and Tuckey’s HSD test, it is determined a statistically significant difference between all countries in the group, while in the case of Serbia, it can notice there is a statistically significant difference between other countries in the region, except for Montenegro, where there is no statistical significance.
Work statistics in the periodically driven quartic oscillator: classical versus quantum dynamics

description: In the thermodynamics of nanoscopic systems the relation between classical and quantum mechanical description is of particular importance. To scrutinize this correspondence we study an anharmonic oscillator driven by a periodic external force with slowly varying amplitude both classically and within the framework of quantum mechanics. The energy change of the oscillator induced by the driving is closely related to the probability distribution of work for the system. With the amplitude $λ(t)$ of the drive increasing from zero to a maximum $λ_{max}$ and then going back to zero again initial and final Hamiltonian coincide. The main quantity of interest is then the probability density $P(E_f|E_i)$ for transitions from initial energy $E_i$ to final energy $E_f$. In the classical case non-diagonal transitions with $E_f\neq E_i$ mainly arise due to the mechanism of separatrix crossing. We show that approximate analytical results within the pendulum approximation are in accordance with numerical simulations. In the quantum case numerically exact results are complemented with analytical arguments employing Floquet theory. For both classical and quantum case we provide an intuitive explanation for the periodic variation of $P(E_f|E_i)$ with the maximal amplitude $λ_{max}$ of the driving.

description: The aim of this paper is to evaluate the banks` credit policies in Macedonia in comparison to the developed countries before and after the 2008 crisis. In particular, it assesses the credit policies and whether and how the policies were amended following the global recession. In this regard, we formulate two research questions which we tend to analyze based on the collected data. The research is based on a quantitative approach using interviews with senior and middle credit managers from twenty banks in Macedonia, SEE and USA to analyze the changes in their credit policies. The results provide the following findings: 1) The credit policies of the Macedonian banks are more conservative than those of foreign banks in both observed periods; and 2) The financial crisis impacted the credit policies of all observed banks, yet the impact is stronger within the SEE and the USA banks. The obtained results might be of interest for ongoing improvement of the banks` credit and risk management, as well as for the policy makers to prevent future financial crises.

description: Very light pseudoscalars can arise from the symmetry-breaking sector in many extensions of the Standard Model. If their mass is below 200 MeV, they can be long-lived and have interesting phenomenology. We discuss the experimental constraints on several models with light pseudoscalars, including one in which the pseudoscalar is naturally fermiophobic. Taking into account the stringent bounds from rare K and B decays, we find allowed parameter space in each model that may be accessible in direct production experiments. In particular, we study the photoproduction of light pseudoscalars at Jefferson Lab and conclude that a beam dump experiment could explore some of the allowed parameter space of these models.

TYPE SPECIES. — Nomia elegans Smith, 1857.
ETYMOLOGY. — The new subgeneric name is a combination of the Ancient Greek adjective σπᾰ́νῐΟς (spánios), meaning, “sparse” or “rare”, and the generic name Nomia Latreille. The gender of the name is feminine.
DIAGNOSIS. — This subgenus is quite distinctive from all other Maculonomia for the comparatively sparse setation of the metatibial scopa and the light coloration of the legs, which are also rather thin in the male, and with scarcely any apical lobe present on the metatibia (versus the well-developed lobes of Maculonomia s.str.). Aside from the type species the subgenus also includes Maculonomia concinna Smith, 1860.

description: A ferromagnetic insulating (FM-I) state in Pr0.75Ca0.25MnO3 has been studied by neutron scattering experiment and theoretical calculation. The insulating behavior is robust against an external magnetic field, and is ascribed to neither the phase separation between a ferromagnetic metallic (FM-M) phase and a non-ferromagnetic insulating one, nor the charge ordering. We found that the Jahn-Teller type lattice distortion is much weaker than PrMnO3 and the magnetic interaction is almost isotropic. These features resembles the ferromagnetic metallic state of manganites, but the spin exchange interaction J is much reduced compared to the FM-M state. The theoretical calculation based on the staggered type orbital order well reproduces several features of the spin and orbital state in the FM-I phase.

description: Detecting cosmic gamma rays at high rates is the key to time-resolve the acceleration of particles within some of the most powerful events in the universe. Time-resolving the emission of gamma rays from merging celestial bodies, apparently random bursts of gamma rays, recurring novas in binary systems, flaring jets from active galactic nuclei, clocking pulsars, and many more became a critical contribution to astronomy. For good timing on account of high rates, we would ideally collect the naturally more abundant, low energetic gamma rays in the domain of one giga electronvolt in large areas. Satellites detect low energetic gamma rays but only in small collecting areas. Cherenkov telescopes have large collecting areas but can only detect the rare, high energetic gamma rays. To detect gamma rays with lower energies, Cherenkov-telescopes need to increase in precision and size. But when we push the concept of the -- far/tele -- seeing Cherenkov telescope accordingly, the telescope's physical limits show more clearly. The narrower depth-of-field of larger mirrors, the aberrations of mirrors, and the deformations of mirrors and mechanics all blur the telescope's image. To overcome these limits, we propose to record the -- full/plenum -- Cherenkov-light field of an atmospheric shower, i.e. recording the directions and impacts of each individual Cherenkov photon simultaneously, with a novel class of instrument. This novel Cherenkov plenoscope can turn a narrow depth-of-field into the perception of depth, can compensate aberrations, and can tolerate deformations. We design a Cherenkov plenoscope to explore timing by detecting low energetic gamma rays in large areas.

description: Assemblies of nanocrystals with complex morphologies have solicited great scientific interest. Controlling the formation of these self-assembled structures has proved difficult. Here we present a novel transformation reaction for transforming a single crystal of minerals into assemblies of nanocrystals of substances with lower solubility without changing the overall morphology. This study focusses on the transformation of rhombohedral calcite crystals to assemblies of hydroxyapatite nanocrystals to control the transformation process. This yielded particle assemblies of HAP nanoparticles grossly preserving the original rhombohedral calcite morphology.

description: The purpose of model selection algorithms such as All Subsets, Forward Selection and Backward Elimination is to choose a linear model on the basis of the same set of data to which the model will be applied. Typically we have available a large collection of possible covariates from which we hope to select a parsimonious set for the efficient prediction of a response variable. Least Angle Regression (LARS), a new model selection algorithm, is a useful and less greedy version of traditional forward selection methods. Three main properties are derived: (1) A simple modification of the LARS algorithm implements the Lasso, an attractive version of ordinary least squares that constrains the sum of the absolute regression coefficients; the LARS modification calculates all possible Lasso estimates for a given problem, using an order of magnitude less computer time than previous methods. (2) A different LARS modification efficiently implements Forward Stagewise linear regression, another promising new model selection method;

description: With a series of numerical simulations, we analyze the thermo-hydrodynamical evolution of circumstellar disks containing Jupiter-size protoplanets. In the framework of the two-dimensional approximation, we consider an energy equation that includes viscous heating and radiative effects in a simplified, yet consistent form. Multiple nested grids are used in order to study both global and local features around the planet. By means of different viscosity prescriptions, we investigate various temperature regimes. A planetary mass range from 0.1 to 1 Mj is examined. Computations show that gap formation is a general property which affects density, pressure, temperature, optical thickness, and radiated flux distributions. However, it remains a prominent feature only when the kinematic viscosity is on the order of 10^(15) cm^2/s or lower. Around accreting planets, a circumplanetary disk forms that has a surface density profile decaying exponentially with the distance and whose mass is 5-6 orders of magnitudes smaller than Jupiter's mass. Circumplanetary disk temperature profiles decline roughly as the inverse of the distance from the planet. Temperatures range from some 10 to ~1000 K. Planetary accretion and migration rates depend on the viscosity regime, with discrepancies within an order of magnitude. Estimates of growth and migration time scales inferred by these models are on the same orders of magnitude as those previously obtained with locally isothermal simulations.

description: We establish covariant semiclassical transport equations of massive spin-1/2 particles which are generated by the quantum kinetic equation modified by enthalpy current dependent terms. The purpose of modification is to take into account the noninertial properties due to the angular velocity of rotating frame which is equivalent to the fluid vorticity in hydrodynamical approach. We present the equations satisfied by the Wigner function components and by studying their solution in the semiclassical approximation we accomplish the transport equations. To acquire a three-dimensional kinetic theory, the relativistic kinetic equations in the comoving frame are integrated over the zeroth component of four-momentum. The resulting vector and axial-vector currents are calculated at zero temperature. There exists another three-dimensional formulation of Dirac particles which correctly addresses the noninertial features of rotating coordinates. We review it briefly and obtain the mass corrections to the chiral vector and axial-vector currents produced by this formulation.

description: Although the impact of insecurity on agricultural decisions is widely discussed, it remains largely unstudied empirically. This study estimates the effect of risk of violence on livestock and crop portfolios using spatially disaggregated risk measures and data from over 690,000 households, approximately 75 per cent of all rural households in Northern Uganda. As the risk of violence increases, households decrease their livestock holdings while shifting its composition towards smaller, less risky animals that can be kept within villages. The similarly strong shifts in the choice of crops, however, are not always consistent with a shift towards less risky crops. Since households remain reliant on agriculture, these ex ante behavioural responses to insecurity suggest important consequences for welfare.

description: C++ Modules come in C++20 to fix the long-standing build scalability problems in the language. They provide an io-efficient, on-disk representation capable to reduce build times and peak memory usage. ROOT employs the C++ modules technology further in the ROOT dictionary system to improve its performance and reduce the memory footprint. ROOT with C++ Modules was released as a technology preview in fall 2018, after intensive development during the last few years. The current state is ready for production, however, there is still room for performance optimizations. In this talk, we show the roadmap for making the technology default in ROOT. We demonstrate a global module indexing optimization which allows reducing the memory footprint dramatically for many workflows. We will report user feedback on the migration to ROOT with C++ Modules.

description: We show that the lowest nontrivial truncation of the two-particle irreducible (2PI) effective action correctly determines transport coefficients in a weak coupling or 1/N expansion at leading (logarithmic) order in several relativistic field theories. In particular, we consider a single real scalar field with cubic and quartic interactions in the loop expansion, the O(N) model in the 2PI-1/N expansion, and QED with a single and many fermion fields. Therefore, these truncations will provide a correct description, to leading (logarithmic) order, of the long time behavior of these systems, i.e. the approach to equilibrium. This supports the promising results obtained for the dynamics of quantum fields out of equilibrium using 2PI effective action techniques.

description: A novel nonlinear sigma model method is proposed for the two-dimensional J1-J2 model, which is extended to include plaquette-type distortion. The nonlinear sigma model is properly derived without spoiling the original spin degrees of freedom. The method shows that a single disordered phase continuously extends from a frustrated uniform regime to an unfrustrated distorted regime. By the continuity and Oshikawa's commensurability condition, the disordered ground states for the uniform J1-J2 model are plaquette states with four-fold degeneracy.

description: It is well-known that an antichain in the poset $[0,1]^n$ must have measure zero. Engel, Mitsis, Pelekis and Reiher showed that in fact it must have $(n-1)$-dimensional Hausdorff measure at most $n$, and they conjectured that this bound can be attained. In this note we show that, for every $n$, such an antichain does indeed exist.

description: We report on a calculation of the growth of the mass of supermassive black holes at galactic centers from dark matter and Eddington - limited baryonic accretion. Assuming that dark matter halos are made of fermions and harbor compact degenerate Fermi balls of masses from $10^{3}M_{\odot}$ to $10^{6}M_{\odot}$, we find that dark matter accretion can boost the mass of seed black holes from about $\sim 5M_{\odot}$ to $10^{3-4}M_{\odot}$ black holes, which then grow by Eddington - limited baryonic accretion to supermassive black holes of $10^{6 - 9}M_{\odot}$. We then show that the formation of the recently detected supermassive black hole of $3\times 10^{9}M_{\odot}$ at a redshift of $z = 6.41$ in the quasar SDSS J114816.64+525150.3 could be understood if the black hole completely consumes the degenerate Fermi ball and then grows by Eddington - limited baryonic accretion. In the context of this model we constrain the dark matter particle masses to be within the range from 12 ${\rm keV/c}^{2}$ to about 450 ${\rm keV/c}^{2}$. Finally we investigate the black hole growth dependence on the formation time of the seed BH and on the mass of the seed BH. We find that in order to fit the observed data point of $M_{BH} \sim 3 \times 10^{9}M_{\odot}$ and $z \sim 6.41$, dark matter accretion cannot start later than about $2 \times 10^{8}$ years and the seed BH cannot be greater than about $10^{4}M_{\odot}$. Our results are in full agreement with the WMAP observations that indicate that the first onset of star formation might have occurred at a redshift of $z \sim 15 - 20$. For other models of dark matter particle masses, corresponding constraints may be derived from the growth of black holes in the center of galaxies.

description: We present a formal proof strategy for the Collatz Conjecture using recursive descent,parity-based reduction, and bounded drift analysis. We define a potential functionthat captures logarithmic entropy and demonstrate that all orbits under the Collatzmap must eventually decrease, eliminating the possibility of divergent trajectories.Unlike previous heuristic or computational approaches, this method builds a rigorousfoundation for inductive descent and proves that all positive integers eventually reachthe 4–2–1 loop. The proof arises from a structure that, while formally mathematical,is motivated by a deeper logical principle: that any escape path under the Collatzfunction ultimately contradicts its own generative rules.
Making Place : Structure as Catalyst Along the Fundy Footpath

description: This graduate project engages with five specific sites located along the Fundy Footpath, a sixty-one kilometer trail that runs along the southern coast of New Brunswick, on the Bay of Fundy. The goal is to create a strong sense of place through small interventions in a remote landscape. This act of place-making serves as a catalyst for developing a sense of community, promoting ecological respect, and fostering a deeper understanding of the natural landscape, while generating important public revenue responsibly through Eco-tourism. For each site that I have chosen, I have designed a building inspired conceptually and aesthetically by site-specific, local architectural precedents rooted in the history of coastal New Brunswick: the lighthouse, the fishing shack, the fishing stand, the smokehouse, and the chapel. These sites and accompanying structures embody a unique investigation of the current relationship that exists between twenty-first-century humans and “the wilderness” and serves a platform for visitors to engage with each other, the natural world, and the history of the region.

description: We provide new evidence on the impact of social protection interventions on household size and the factors that cause the household size to change: fertility, child fosterage, and in and out migration related to work and marriage. Using data from an intervention delivered at scale, Ethiopia’s Productive Safety Net Program (PSNP), we find that participation in the PSNP leads to an increase in household size of 0.3 members. We find no evidence that PSNP participation increases fertility and some evidence that fertility is reduced, specifically it reduces the likelihood that an adult female member gives birth by 8.1 percentage points. We reconcile this seemingly divergent findings by showing that the increase in household size arises from an increase in the number of girls aged 12 to 18 years. We present evidence that this occurs because the PSNP causes households to delay marrying out adolescent females.
Computational design of $f$-electron Kitaev magnets: honeycomb and hyperhoneycomb compounds $A_2$PrO$_3$ ($A=$ alkali metals)

description: The Kitaev spin model offers an exact quantum spin liquid in the ground state, which has stimulated exploration of its material realization over the last decade. Thus far, most of the candidates are found in $4d$- and $5d$-electron compounds, in which the low-spin $d^5$ electron configuration subject to strong spin-orbit coupling comprises a Kramers doublet with the effective angular momentum $j_{\rm eff}=1/2$ and gives rise to the bond-dependent anisotropic interactions in the Kitaev model. Here we theoretically investigate other candidates in $4f$-electron compounds with the $f^1$ electron configuration on both quasi-two-dimensional honeycomb and three-dimensional hyperhoneycomb structures, $A_2$PrO$_3$ with $A$=Li, Na, K, Rb, and Cs. Based on {\it ab initio} calculations, we show that the electronic structures of these compounds host a spin-orbital entangled Kramers doublet with $j_{\rm eff}=1/2$ in the $Γ_7$ state. By constructing the tight-binding Hamiltonian and performing a perturbation expansion, we find that the low-energy magnetic properties of $A_2$PrO$_3$ are well described by an effective spin model with the $J$-$K$-$Γ'$ model. The most remarkable feature is that the Kitaev interaction $K$ is antiferromagnetic, in contrast to the ferromagnetic one in the $d^5$ candidates at hand. The exchange interactions are systematically modulated by changing the $A$-site cations. As a consequence, the compounds with $A$=Li and Na may have a dominant antiferromagnetic $K$, but $J$ dominates $K$ and $Γ'$ in the cases with $A$=Rb and Cs. Also, by computing the ground states of the $J$-$K$-$Γ'$ model by using the exact diagonalization, we map out the systematic evolution of the model parameters in the phase diagram. Our results will stimulate material exploration of the antiferromagnetic Kitaev interaction in $f$-electron compounds.

description: This research presents the results obtained using a bioremediation approach aiming to enhance natural remediation of the Bagnoli-Coroglio area, a post industrial site in the Gulf of Naples, Italy, characterized by the presence of several pollutants released in almost a century by the ILVA steel plant. In particular, the thesis evaluates the benthic microbial taxonomic composition of this area after ten decades of pollution. Results indicate the prevalence of the Phyla Proteobacteria, (36.7%), Planctomycetes (20.5%) and Bacteroidetes (9.6%) and the presence of a core microbiome suggesting that pollutants and other abiotic factors may have contributed to shape benthic prokaryotic communities. The thesis also evaluates the biotechnological potential of single isolates bacteria (Halomonas sp., Alcanivorax sp., Epibacterium sp., Pseudoalteromonas sp., and Virgibacillus sp.) and mixtures of these species isolated from polluted sediments collected from Bagnoli-Coroglio area and the Sarno river mouth, another polluted site in the Gulf of Naples. Laboratory tests highlighted the ability of mixed cultures and single taxa to degrade PAHs (Polyclic Aromatic Hydrocarbons) and precipitate heavy metals from culture media. Results of Sequential Selective Extraction (SSE) analysis emphasized the ability of mixed cultures to reduce the mobility of As, Cd and Zn by changing their partitioning in the geochemical fractions. Full genome sequencing of isolated strains has allowed for the genetic and molecular characterization of mechanisms underlying processes of degradation and detoxification of xenobiotics. In particular, many genes involved in hydrocarbon degradation pathways and in heavy metal detoxification systems have been identified. My results suggest a potential biotechnological application of these strains in waste-water treatment as well as decontamination of polluted sediments.
To be or not to Be? - First Evidence for Neutrinoless Double Beta Decay

description: Double beta decay is indispensable to solve the question of the neutrino mass matrix together with $ν$ oscillation experiments. Recent analysis of the most sensitive experiment since nine years - the HEIDELBERG-MOSCOW experiment in Gran-Sasso - yields a first indication for the neutrinoless decay mode. This result is the first evidence for lepton number violation and proves the neutrino to be a Majorana particle. We give the present status of the analysis in this report. It excludes several of the neutrino mass scenarios allowed from present neutrino oscillation experiments - only degenerate scenarios and those with inverse mass hierarchy survive. This result allows neutrinos to still play an important role as dark matter in the Universe. To improve the accuracy of the present result, considerably enlarged experiments are required, such as GENIUS. A GENIUS Test Facility has been funded and will come into operation by early 2003.

description: Salt-induced redox and ion imbalance may lead to increased oxidative stress and impair the plant growth. However, among the many reactive oxygen species (ROS) produced under stress, hydrogen peroxide (H2O2) plays a central role in several signal transduction pathways triggering a series of physiological mechanisms and increase plant tolerance to salt stress. Thus, this study aimed to evaluate the changes in the balance of inorganic and organic solutes induced by seed priming with H2O2 in leaves and roots of sunflower plants grown under salt stress. In this study, six treatments were tested: T1 - control (absence of NaCl and absence of H2O2); T2 - salt control (presence of 100 mM NaCl and absence of H2O2); T3 − 100 mM H2O2 (12 h) + 100 mM NaCl; T4 − 10 mM H2O2 (12 h) + 100 mM NaCl; T5 − 1 mM H2O2 (24 h) + 100 mM NaCl; T6 − 0.1 mM H2O2 (36 h) + 100 mM NaCl. Our results show that, the role of H2O2 in increase of the salt tolerance is directly associated with reduction on Na+ (on average 46%) and Cl- (on average 24%) contents in the leaves, besides a positive regulation of K+ and NO3- absorption (for three harvests). In addition, H2O2 priming also decreased the oxidative damage, mainly by increasing the activity of catalase enzyme (CAT) in leaves (on average 49% at 2nd and 3rd harvests) and roots (on average 39% at 3rd harvest).

description: Calcium carbonate (CaCO3) was synthesized from diverse water-free alcohol solutions, resulting in the formation of vaterite and calcite precipitates, or stable particle supensions, with dimension and morphology depending upon the condition used. The obtained results shed light on the importance of water molecules during crystallization of CaCO3 and open a novel synthetic route for its precipitation in organic solvents.
