description: We have synthesized a series of the Ruddlesden-Popper nickelate solid solution Ln4-xLn'xNi3O10 (Ln and Ln' = La, Pr and Nd; x = 0, 1, 2 and 3) via the citrate precursor method at different reacting atmospheres. Both the electronic-transport and magnetization measurements on these samples show well-defined phase transitions at temperatures between 135 K and 165 K. These transition temperatures, the room-temperature resistivities, as well as the changes of the Pauli-paramagnetic susceptibilities at the respective phase transitions, strongly correlate with the Goldschmidt tolerance factor t, irrespective of the combination of the magnetic rare-earth ions with unmagnetic La3+. We conclude that these changes of the electronic properties are mostly related to the distortion of the NiO6 octahedra at the phase transition which is strongly correlated with the tolerance factor t, but are rather insensitive to the magnetism of the rare-earth ions Ln3+ and Ln'3+.

description: The Open Cluster Chemical Abundances and Mapping (OCCAM) survey aims to constrain key Galactic dynamical and chemical evolution parameters by the construction of a large, comprehensive, uniform, infrared-based spectroscopic data set of hundreds of open clusters. This fourth contribution from the OCCAM survey presents analysis using SDSS/APOGEE DR16 of a sample of 128 open clusters, 71 of which we designate to be "high quality" based on the appearance of their color-magnitude diagram. We find the APOGEE DR16 derived [Fe/H] abundances to be in good agreement with previous high resolution spectroscopic open cluster abundance studies. Using the high quality sample, we measure Galactic abundance gradients in 16 elements, and find evolution of some of the [X/Fe] gradients as a function of age. We find an overall Galactic [Fe/H] vs R_GC gradient of $-0.068 \pm 0.001$ dex kpc$^{-1}$ over the range of $6

The worldwide governance indicators and tautology : Casually related separable concepts, indicators of a common cause, or both?
Creators: name: Langbein, Laura

Publisher: name: American University
Year: 2023

description: Aggregate indexes of the quality of governance, covering large samples of countries, are widely used in research and in aid policy. Few studies examine the validity of these indexes, however. This paper partially fills this gap by examining empirically the dimensionality of the Worldwide Governance Indicators. The six indexes purportedly measure distinct concepts of control of corruption, rule of law, government effectiveness, regulatory quality, political stability, and voice and accountability. Using standard statistical techniques for testing measurement validity, the analysis concludes that the six indexes do not discriminate usefully among different aspects of governance. Rather, each of the indexes merely reflects perceptions of the quality of governance more broadly. An implication of the findings is that the Worldwide Governance Indicator indexes are frequently misused in research and policy applications, where it is commonly assumed that the indexes provide distinct measures of different aspects of the quality of governance. A further implication is that Transparency International's even more widely-known aggregate index similarly reflects perceptions not only of corruption, as intended, but of the quality of governance more broadly.

The Young tableaux theory was extended to affine Hecke algebras (of general Lie type) in recent work of A. Ram. We also show how (in general Lie type) the representations of general affine Hecke algebras can be constructed from the representations of simply connected affine Hecke algebras by using an extended form of Clifford theory. This extension of Clifford theory is given in the Appendix.

Viva La Differénce? The impact of diversity on the job satisfaction of public employees and performance of public agencies

description: This paper addresses previous shortcomings in diversity management scholarship by testing an expanded diversity model borrowed from the work of economist Scott Page. Page‘s model assumes diversity can be measured as both a mean and a variance, and that it consists of cognitive, identity, and preference characteristics. We link his conceptualization of diversity to both individual-level outcomes and organizational productivity. Results indicate that identity diversity reduces agency productivity and increases turnover intentions, while cognitive diversity has small and mixed effects. Findings also suggest that individual employee discretion as well as overall discretion in the agency shape outcomes in more important ways than diversity, and that the impact of agency size is contingent on overall discretion in the agency. We conclude with a discussion on the theoretical ramifications of our findings.

Floating, critical and dimerized phases in a frustrated spin-3/2 chain

description: We study spontaneous dimerization and emergent criticality in a spin-3/2 chain with antiferromagnetic nearest-neighbor $J_1$, next-nearest-neighbor $J_2$ and three-site $J_3$ interactions. In the absence of three-site interaction $J_3$, we provide evidence that the model undergoes a remarkable sequence of three phase transitions as a function of $J_2/J_1$, going successively through a critical commesurate phase, a partially dimerized gapped phase, a critical floating phase with quasi-long-range incommensurate order, to end up in a fully dimerized phase at very large $J_2/J_1$. In the field theory language, this implies that the coupling constant of the marginal operator responsible for dimerization changes sign three times. For large enough $J_3$, the fully dimerized phase is stabilized for all $J_2$, and the phase transitions between the critical phases and this phase are both Wess-Zumino-Witten (WZW) SU(2)$_3$ along part of the boundary and turn first order at some point due to the presence of a marginal operator in the WZW SU(2)$_3$ model. By contrast, the transition between the two dimerized phase is always first order, and the phase transitions between the partially dimerized phase and the critical phases are Kosterlitz-Thouless. Finally, we discuss the intriguing spin-1/2 edge states that emerge in the partially dimerized phase for even chains. Unlike their counterparts in the spin-1 chain, they are not confined and disappear upon increasing $J_2$ in favour of a reorganization of the dimerization pattern.

description: We show that the simultaneous measurement of yields and fluctuations in heavy ion collisions is capable of falsifying and constraining the statistical hadronization model. We show how such a measurement can test for chemical non-equilibrium, and distinguish between a high temperature chemically equilibrated freeze-out from a supercooled freeze-out with an over-saturated phase space. We further explain how this measurement can be used to obtain a model-independent estimate of the effect of post-freezeout hadronic interactions.

Molecular characterisation and physiological adaptations of cowpea to growth temperature

description: This research focuses on characterising Rubisco activase expression in cowpea, as well as physiological adaptations of cowpea, Vigna unguiculata, to different temperatures. Cowpea is a drought-tolerant crop, however, increase in temperature and weather instability due to global warming can produce conditions which would stretch even cowpea tolerance to its limit. Here, physiological adaptations of cowpea to changing temperatures are characterised, and rubisco activase (Rca) expression is determined to aid in understanding temperature effects on cowpea. No previous work has been done to measure Rca expression in cowpea. Whilst some work has been done on characterising cowpea physiological responses to temperature, it has been focusing on long-term effects, and this study aims to quantify physiological adaptations during first four growth stages (until full unfolding of second trifoliate). A process for RNA extraction from cowpea leaves was optimised, a set of primers differentiating between different Rca isoforms was designed and tested, and a set of candidate reference genes was selected and tested for stability. This was used to perform qPCR to determine leaf Rca expression levels. Daily physiological observations were taken to quantify physiological adaptations. No significant difference in expression between first and second trifoliate leaves was observed for isoforms 1β, 8α, 8ββ, and 10α. There was some difference in expression for isoform 10β, but the scientific significance of this observation is hard to determine. The most expressed isoform was 1β. Isoform 8α was second most expressed followed by 8ββ, 10β and 10α. Physiologically, chlorophyll density tended to be correlated with temperature, whereas leaf size, above ground biomass, and LMA tended to be inversely correlated to growth temperature. These results could be used for further study into physiological and molecular adaptations of Cowpea to different environmental temperatures.

description: The trans-Planckian censorship conjecture implies that single-field models of inflation require an extreme fine-tuning of the initial conditions due to the very low-scale of inflation. In this work, we show how a quantum cosmological proposal -- namely the tunneling wavefunction -- naturally provides the necessary initial conditions without requiring such fine-tunings. More generally, we show how the tunneling wavefunction can provide suitable initial conditions for hilltop inflation models, the latter being typically preferred by the swampland constraints.

description: Autonomous entanglement engines have recently been proposed to generate steady-state bipartite and multipartite entanglement exploiting only incoherent interactions with thermal baths at different temperatures. In this work, we investigate the interplay between heat current and entanglement in a two-qubit entanglement engine, deriving a critical heat current for successful operation of the engine, i.e. a cut-off above which entanglement is present. The heat current can thus be seen as a witness to the presence of entanglement. In the regime of weak-inter qubit coupling, we also investigate the effect of two experimentally relevant parameters for the qubits, the energy detuning and tunnelling, on the entanglement production. Finally, we show that the regime of strong inter-qubit coupling provides no clear advantage over the weak regime, in the context of out-of-equilibrium entanglement engines.

Preliminary Investigations towards the Water Uptake in HLFC

Subjects: HLFC, water uptake, microperforated surface, titanium skin

description: Hybrid Laminar Flow Control (HLFC) is a technology to reduce the aircraft fuel consumption by
 sucking air through a micro-perforated outer titanium skin, thus increasing laminar flow length.
 Introducing this technology raises new operational challenges, which need to be investigated. One of
 them is the uptake of water through the micro-perforated skin. In the literature, only very limited
 information regarding the water uptake of perforated titanium sheets can be found.
 During the design of a HLFC-wing system, it is of high importance to know whether water will
 accumulate in the leading edge. Therefore, this work focuses on simplified mechanisms of water
 uptake of microperforated titanium samples and determining critical cases. In order to achieve this,
 relevant scenarios are identified and simple tests to simulate them are conducted.
 Basically, the cases were divided into flight conditions, like cloud encounter, and ground conditions,
 such as parking in rain and the de-/anti-icing procedure. The tests show that a certain pressure on
 the skin is required in order to force an uptake. For the used titanium sample (0.8 mm thickness)
 with a hole diameter of 55 µm and a pitch of 600 µm, this pressure is higher than the pressure
 caused by rain on the parked aircraft. In contrast to rain on ground, flight conditions lead to pressure
 levels that will force a water uptake. For this test case, a correlation between angle and water uptake
 is additionally investigated. However, detailed tests are proposed to reliably quantify this aspect as
 well.
 Due to the observed water uptake, the design of a HLFC system has to include an appropriate
 drainage system.

description: The $k$ nearest neighbour learning rule (under the uniform distance tie breaking) is universally consistent in every metric space $X$ that is sigma-finite dimensional in the sense of Nagata. This was pointed out by Cérou and Guyader (2006) as a consequence of the main result by those authors, combined with a theorem in real analysis sketched by D. Preiss (1971) (and elaborated in detail by Assouad and Quentin de Gromard (2006)). We show that it is possible to give a direct proof along the same lines as the original theorem of Charles J. Stone (1977) about the universal consistency of the $k$-NN classifier in the finite dimensional Euclidean space. The generalization is non-trivial because of the distance ties being more prevalent in the non-euclidean setting, and on the way we investigate the relevant geometric properties of the metrics and the limitations of the Stone argument, by constructing various examples.

Viva La Differénce? The impact of diversity on the job satisfaction of public employees and performance of public agencies
Creators: name: Langbein, Laura
name: Stazyk, Edmund C.
Publisher: name: American University
Year: 2023

description: This paper addresses previous shortcomings in diversity management scholarship by testing an expanded diversity model borrowed from the work of economist Scott Page. Page‘s model assumes diversity can be measured as both a mean and a variance, and that it consists of cognitive, identity, and preference characteristics. We link his conceptualization of diversity to both individual-level outcomes and organizational productivity. Results indicate that identity diversity reduces agency productivity and increases turnover intentions, while cognitive diversity has small and mixed effects. Findings also suggest that individual employee discretion as well as overall discretion in the agency shape outcomes in more important ways than diversity, and that the impact of agency size is contingent on overall discretion in the agency. We conclude with a discussion on the theoretical ramifications of our findings.

An investigation into new SUB rooftop garden irrigations systems

description: The new Student Union Building (SUB) is designed to be a Leadership in Energy and Environmental Design (LEED) Platinum + rated sustainable building. One of the new features of the SUB is a rooftop garden capable of producing food for businesses and food retail outlets. Vancouver has a very moist climate, with long, wet winters; however, hot, dry periods are common during the summer. Therefore, it is necessary to install an irrigation system to keep the garden sufficiently watered during these periods. There is a wide range of solutions to the irrigation problem for the rooftop garden. In order to gain or surpass a LEEDS Platinum + standing, the system with the lowest carbon footprint, and highest water efficiency must be chosen. However, due to the limited space for planting crops, the system must be effective in maintaining crop health and maximizing yield. Based on these constraints, the selected system should employ micro-irrigation. These systems are designed to apply moisture directly to the plants or root zone soil. Whiffen (1991) states “an irrigation system designed to operate at 40 psi can require up to twice as much energy as an irrigation system designed for a pressure of 10 psi”. As micro-irrigation systems send water near the root zone, it saves water from evaporation and runoff, reducing energy costs. Additionally, “the ability of micro-irrigation systems to place most of the irrigation water where it can be used by the crop reduces the amount of which needs to be pumped through the irrigation system to supply the entire crop water needs” (Whiffen, 1991). An 80 percent improvement in water efficiency was observed by using micro irrigation systems, as opposed to conventional practices. This report is a triple bottom-line assessment of the two most common micro-irrigation systems: sprinklers and drip tape. The following analysis is intended to aid in the selection and design of the rooftop irrigation system for the new SUB.

description: Federal funding of economics and marketing economics at state agricultural experiment stations declined substantially between 1970 and 1985. Associated with the decline was removal in 1977 of the requirement that 20 percent of added Hatch funds be on marketing. Relative increases in nonfederal support, particularly state appropriations, were important in sustaining research in economics and marketing economics.
Large amplitude spin waves in ultra-cold gases

description: We discuss the theory of spin waves in non-degenerate ultra-cold gases, and compare various methods which can be used to obtain appropriate kinetic equations. We then study non-hydrodynamic situations, where the amplitude of spin waves is sufficiently large to bring the system far from local equilibrium. In the first part of the article, we compare two general methods which can be used to derive a kinetic equation for a dilute gas of atoms (bosons or fermions) with two internal states (treated as a pseudo-spin 1/2). The collisional methods are in the spirit of Boltzmann's original derivation of his kinetic equation where, at each point of space, the effects of all sorts of possible binary collisions are added. We discuss two different versions of collisional methods, the Yvon-Snider approach and the S matrix approach. The second method uses the notion of mean field, which modifies the drift term of the kinetic equation, in the line of the Landau theory of transport in quantum liquids. For a dilute cold gas, it turns out that all these derivations lead to the same drift terms in the transport equation, but differ in the precise expression of the collision integral and in higher order gradient terms. In the second part of the article, the kinetic equation is applied to spin waves in trapped ultra-cold gases. Numerical simulations are used to illustrate the strongly non-hydrodynamic character of the spin waves recently observed with trapped Rb87 atoms. The decay of the phenomenon, which takes place when the system relaxes back towards equilibrium, is also discussed, with a short comment on decoherence.

Hopping charge transport in amorphous organic and inorganic materials with spatially correlated random energy landscape

description: General properties of the hopping transport of charge carriers in amorphous organic and inorganic materials are discussed. We consider the case where the random energy landscape in the materials is strongly spatially correlated. This is a very typical situation in the organic materials having the Gaussian density of states (DOS) and may be realized in some materials with the exponential DOS. We demonstrate that the different type of DOS leads to a very different functional form of the mobility field dependence even in the case of the identical correlation function of random energy. We provide important arguments in favor of the significant contribution of the local orientational order to the total magnitude of the energetic disorder in organic materials. A simple but promising model of charge transport in highly anisotropic composites materials is suggested.

description: This study examined culture and sustainable tax compliance in Nigeria. Governments must earn sufficient revenue to fulfill their fiduciary commitments to citizens. This public money can be produced through a variety of means, the most stable and sustainable of which is taxation. However, residents are not naturally obligated to pay taxes honestly, lowering the volume of potential revenue. The broad objective of this conceptual paper is to examine culture and sustainable tax compliance in Nigeria. The methodology adopted for this study is library approach which focuses on content review of extant literature on culture and sustainable tax compliance in Nigeria. We concluded that culture exerts significant influence on tax compliance of individual taxpayers and that each of the Hofstede's cultural dimensions is found to show strong influence on tax compliance. Furthermore, government transparency and accountability in taxation are critical to taxpayer confidence since a lack of trust in the tax system and government can lead to tax evasion and dishonesty. In order to attain the best results, the study advised that the Nigerian government and other important players ensure that culture is generally recognized in tax policy creation, law enactment, and tax administration procedures. In addition, tax authorities should be sufficiently supported, and loopholes in relevant tax legislation should be closed.

Constraints on Nucleon Decay via "Invisible" Modes from the Sudbury Neutrino Observatory
Creators: name: SNO Collaboration
Publisher: name: arXiv
Year: 2003
Subjects: subject: High Energy Physics - Experiment (hep-ex)
subject: FOS: Physical sciences

description: Data from the Sudbury Neutrino Observatory have been used to constrain the lifetime for nucleon decay to ``invisible'' modes, such as n -> 3 nu. The analysis was based on a search for gamma-rays from the de-excitation of the residual nucleus that would result from the disappearance of either a proton or neutron from O16. A limit of tau_inv > 2 x 10^{29} years is obtained at 90% confidence for either neutron or proton decay modes. This is about an order of magnitude more stringent than previous constraints on invisible proton decay modes and 400 times more stringent than similar neutron modes.
