Pictorial works

description: One of the standard art-historical exercises is the search for the pictorial sources of individual works of art. The purpose of this article is to suggest that this exercise need not constitute an end in itself, as it usually does, but that it can yield valuable information about the status of an image in a given social context and about the response it evokes. Rubens's modello of The Assumption and Coronation of the Virgin in Leningrad raises a number of iconographic problems; these in turn are largely resolved by the discovery of an important pictorial source for the work. That source and its relation to the work by Rubens may be used as an illustration of some of the ways in which it is possible to determine the associations which the seventeenth-century beholder made when looking at works of art - even when they were not actually recorded by the beholder himself. While it can never be possible to recover the full range of such associations - because many would have been too personal and idiosyncratic - the art historian may regard it as his province to reveal at least some.

description: This study examines the impact of monetary policy on poverty reduction in Nigeria between 1985 and 2019, taking into account other factors that influenced poverty. The institutional quality factors were included as part of independent variables to bridge the gap between monetary policy and poverty reduction in Nigeria. The study used Error Correction Model (ECM) technique for the estimation, and the results show that there exists a strong link between monetary policy and poverty reduction. The findings also reveal that institutional quality, proxy by political and economic institutions, is among the major factors that influence poverty in Nigeria. The study concludes that monetary authority should implement low inflationary monetary policy that will not only encourage investment, raise employment opportunities and economic growth, but also improves wellbeing of the people in the country.

Flexible clap and fling in tiny insect flight

description: Of the insects that have been filmed in flight, those that are 1 mm in length or less often clap their wings together at the end of each upstroke and fling them apart at the beginning of each downstroke. This ;clap and fling' motion is thought to augment the lift forces generated during flight. What has not been highlighted in previous work is that very large forces are required to clap the wings together and to fling the wings apart at the low Reynolds numbers relevant to these tiny insects. In this paper, we use the immersed boundary method to simulate clap and fling in rigid and flexible wings. We find that the drag forces generated during fling with rigid wings can be up to 10 times larger than what would be produced without the effects of wing-wing interaction. As the horizontal components of the forces generated during the end of the upstroke and beginning of the downstroke cancel as a result of the motion of the two wings, these forces cannot be used to generate thrust. As a result, clap and fling appears to be rather inefficient for the smallest flying insects. We also add flexibility to the wings and find that the maximum drag force generated during the fling can be reduced by about 50%. In some instances, the net lift forces generated are also improved relative to the rigid wing case.
Inverse Vernier Effects in Coupled Lasers

description: In this report we study the Vernier effect in coupled laser systems consisting of two cavities. We show that depending on the nature of their coupling, not only can the "supermodes" formed at the overlapping resonances of the coupled cavities have the lowest thresholds and lase first as previously suggested, leading to a manifestation of the typical Vernier effect now in an active system; these supermodes can also have increased thresholds and are hence suppressed, which can be viewed as an inverse Vernier effect. We attribute this effect to detuning-dependent Q-spoiling, and it can lead to an increased free spectrum range and possibly single-mode lasing, which may explain the experimental findings of several previous work. We illustrate this effect using two coupled micro-ring cavities and a micro-ring cavity coupled to a slab cavity, and we discuss its relation to the existence of exceptional points in coupled lasers.

description: We study the possibility of realizing a growth rate of matter density perturbations lower than that in General Relativity. Using the approach of the effective field theory of modified gravity encompassing theories beyond Horndeski, we derive the effective gravitational coupling $G_{\rm eff}$ and the gravitational slip parameter $η$ for perturbations deep inside the Hubble radius. In Horndeski theories we derive a necessary condition for achieving weak gravity associated with tensor perturbations, but this is not a sufficient condition due to the presence of a scalar-matter interaction that always enhances $G_{\rm eff}$. Beyond the Horndeski domain it is possible to realize $G_{\rm eff}$ smaller than Newton's gravitational constant $G$, while the scalar and tensor perturbations satisfy no-ghost and stability conditions. We present a concrete dark energy scenario with varying $c_{\rm t}$ and numerically study the evolution of perturbations to confront the model with the observations of redshift-space distortions and weak lensing.

description: Molecular ions can be held in a chain of laser-cooled atomic ions by sympathetic cooling. This system is ideal for performing high-precision molecular spectroscopy with applications in astrochemistry and fundamental physics. Here we show that this same system can be coupled with a broadband laser to discover new molecular transitions. We use three-ion chains of Ca$^{+}$ and CaH$^{+}$ to observe vibrational transitions via resonance enhanced multiphoton dissociation detected by Ca$^{+}$ fluorescence. Based on theoretical calculations, we assign the observed peaks to the transition from the ground vibrational state, $ν=0$, to $ν=9$ and $ν=10$. Our method allows us to track single molecular events, and it can be extended to work with any molecule by using normal mode frequency shifts to detect the dissociation. This survey spectroscopy serves as a bridge to the precision spectroscopy required for molecular ion control.

description: Males should adjust their behavior and its neural substrates according to the quality of competition that they assess by eavesdropping on other males' courtship signals. In European starlings (Sturnus vulgaris), females base mate choice, in part, on aspects of male song associated with its length, which positively correlates with the males' reproductive success, immunocompetence, age and ability to repel competing males. To determine how variation in the quality of male courtship song affects the brain and behavior of incidental male receivers, we exposed adult male starlings to either long or short songs periodically over 7 days, followed by 1 day of no song. We found no difference between groups in the length (i.e. quality) of songs that subjects produced during the experiment. However, compared with males exposed to short songs, those exposed to long songs sang more songs, exhibited more non-singing activity and, by the end of the experiment, weighed less and had a 30% larger robust nucleus of the arcopallium (RA), a forebrain nucleus that translates pre-motor signals into the appropriate combination of respiratory and syringeal activity. The change in RA volume was not entirely due to variation in song output, suggesting, for the first time, the possibility of acoustically driven plasticity in this motor nucleus. We hypothesize that such neuroplasticity helps prepare the individual for future song output tailored to the prevailing competitive environment.

Nonequilibrium steady-state fluctuations are found to be described by a set of mode-temperatures, independent of the strengths of both the harmonic interaction and the viscous damping. Energy is equally distributed between the conjugate variables of a given mode but differently among different modes, in a manner which depends exclusively on the bath temperatures and on the boundary conditions. We outline how bath-temperature profiles can be designed to enhance or reduce fluctuations at specific frequencies in the power spectrum of the chain length.

description: The purpose of the ENVIEVAL Handbook is to provide guidance on a methodological framework for use in the evaluation of the environmental impacts of RDP measures and programmes. The Handbook provides flexible guidance to evaluators and managing authorities on a process for designing evaluations of the net effects of RDP measures and is not an ‘off the shelf’ recipe book. It focuses on the establishment of a suitable counterfactual and the delivery of an assessment of net effects with a requirement for consistency between micro and macro level evaluations. The Handbook presents a range of possible solutions (e.g. counterfactual scenario setup or choice of appropriate methods for data analysis) with an aim of selecting the most appropriate options for use in evaluations. The output is a basis for deciding on the most consistent and cost-effective approach. The Handbook is developed around a logic model of the process of assessing the environmental effects of RDP measures. It functions as a methodological framework, guiding the evaluator and managing authority through the design of the evaluation, suggesting different routes depending upon factors such as data availability or type of indicator selected. The step-by-step flow of the logic model(s) helps in the design of a consistent evaluation workflow. An aim of the Handbook is to help the evaluator to design the ex-ante evaluation in the overall context of the programme, and RDPs and area of interest, in a step-by-step guide for mid-term and ex-post assessments. Competent authorities can use the handbook as support for the overall design of the Terms of References for RDP evaluations. The ENVIEVAL Handbook summarizes the key characteristics, strengths and weaknesses of evaluation methods recommended, or available, for use in addressing the evaluation of net effects and environmental impacts with respect to a range of public goods. The conceptual description of the different evaluation steps is supported by practical examples of their application and fact sheets of the indicators and methods tested in the ENVIEVAL project which provide information about how to address evaluation challenges, as defined by stakeholders. This handbook compliments the range of guidance documents dedicated to the evaluation of RDPs, in particular those developed by the European Evaluation Helpdesk for Rural Development.

Temperature-induced elevation of basal metabolic rate does not affect testis growth in great tits
Creators: name: Visser, Marcel E.
name: Caro, Samuel P.
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 2009

description: SUMMARY The timing of reproduction varies from year to year in many bird species. To adjust their timing to the prevailing conditions of that year, birds use cues from their environment. However, the relative importance of these cues, such as the initial predictive (e.g. photoperiod) and the supplemental factors (e.g. temperature), on the seasonal sexual development are difficult to distinguish. In particular, the fine-tuning effect of temperature on gonadal growth is not well known. One way temperature may affect timing is via its strong effect on energy expenditure as gonadal growth is an energy-demanding process. To study the interaction of photoperiod and temperature on gonadal development, we first exposed 35 individually housed male great tits (Parus major) to mid-long days (after 6 weeks of 8 h L:16 h D at 15°C, photoperiod was set to 13 h L:11 h D at 15°C). Two weeks later, for half of the males the temperature was set to 8°C, and for the other half to 22°C. Unilateral laparotomies were performed at weeks 5 (i.e one week before the birds were transferred to mid-long days), 8 and 11 to measure testis size. Two measures of basal metabolic rate (BMR) were performed at the end of the experiment (weeks 11 and 12). Testis size increased significantly during the course of the experiment, but independently of the temperature treatment. BMR was significantly higher in birds exposed to the cold treatment. These results show that temperature-related elevation of BMR did not impair the long-day-induced testis growth in great tits. As a consequence, temperature may not be a crucial cue and/or constraint factor in the fine-tuning of the gonadal recrudescence in male great tits, and testis growth is not a high energy-demanding seasonal process.

description: We extract the resonant orbits from an N-body bar that is a good representation of the Milky Way, using the method recently introduced by Molloy et al. (2015). By decomposing the bar into its constituent orbit families, we show that they are intimately connected to the boxy-peanut shape of the density. We highlight the imprint due solely to resonant orbits on the kinematic landscape towards the Galactic centre. The resonant orbits are shown to have distinct kinematic features and may be used to explain the cold velocity peak seen in the APOGEE commissioning data (Nidever at al., 2012). We show that high velocity peaks are a natural consequence of the motions of stars in the 2:1 orbit family and that stars on other higher order resonances can contribute to the peaks. The locations of the peaks vary with bar angle and, with the tacit assumption that the observed peaks are due to the 2:1 family, we find that the locations of the high velocity peaks correspond to bar angles in the range 10 < theta_bar < 25 (deg). However, some important questions about the nature of the peaks remain, such as their apparent absence in other surveys of the Bulge and the deviations from symmetry between equivalent fields in the north and south. We show that the absence of a peak in surveys at higher latitudes is likely due to the combination of a less prominent peak and a lower number density of bar supporting orbits at these latitudes.

Stabillity Assessment of Osseointegrated Transfemoral Bone-Implant Systems using Finite Element  Modal Analysis

Year: 2022

The dynamic response of osseointegrated implant systems can be used to evaluate the condition of the bone-implant interface (BII) and implant stability. The primary objective of this work is to develop a simplified dynamic 1D finite element  (FE) model of the OPL transfemoral amputation (TFA) bone- implant system. The model’s intended clinical use is to  compare the collected acceleration response generated from impact with the percutaneous adapter to the model’s prediction and solve for the unknown BII stiffness. The model utilizes linear vibration theory and thus should accurately capture the natural frequencies and mode shapes of interest. A simply supported uniform beam was modelled using Euler-Bernoulli, Rayleigh, and Timoshenko FE beam formulations and compared with the analytical solution for validation. Additionally, a 3D ABAQUS® model was developed and it showed that Timoshenko’s formulation is the most appropriate model due to the significant shearing effects of the higher modes. Afterwards, a simply supported TFA implant system was modelled with the 1D FE code and compared to the 3D ABAQUS® model. The results indicated that the 1D FE model accurately predicted the natural frequencies of interest with a maximum difference of 3.08 %. The interface stiffness was then introduced as a series of springs distributed over the effective length of the stem. The stiffness’ magnitude was controlled by k which was the total stiffness normalized with respect to the volume of the stem’s effective length. The matching between the 1D and 3D models was based on manipulating the k to match the first mode frequency and comparing the results for the remaining modes. This yielded highly similar natural frequencies and mode shapes for a short stem (effective length=115 (mm)) with two extreme interface conditions. The same values of k found for the short stem were then used to perform modal analysis for a long stem (effective length=160 (mm)) and it yielded highly similar results between the 1D and 3D models which indicates that k is independent from the implant’s geometry. The numerical analysis performed in this investigation sets the groundwork for a series of additional in-vitro and in-vivo analysis of TFA  systems and ultimately the development of a non-invasive vibration-based stability measurement system.

description: Cultural emphasis on achieving homeownership is far from natural, but rather is promoted by a number of government policies. This orientation towards homeownership, while providing some benefits, leads to greater socio-spatial inequality. But Millennials are also particularly adversely affected due to housing market challenges associated with life-course changes, high housing costs in the country’s largest and fastest growing cities, and the proliferation of precarious employment. Planners and policymakers should do more to promote a diversity of affordable housing tenures and types, in the interest of creating just and sustainable communities for all.
description: La culture qui met l’accent sur l’accès à la propriété est loin d’être naturelle. Ce sont plutôt un certain nombre de politiques gouvernementales qui en font la promotion. Cette orientation vers l’accès à la propriété comprend sans doute quelques avantages, mais engendre tout de même une plus grande inégalité sur le plan socio-spatial. La génération Y est particulièrement touchée en raison de problèmes d’accès au marché locatif associés à des changements survenus au cours de la vie, les coûts élevés de l’immobilier et la prolifération d’emplois précaires. Les urbanistes et les décideurs politiques devraient en faire davantage pour promouvoir la diversité en ce qui concerne le type de logements et le mode d’occupation, en vue de créer des collectivités équitables et durables pour tous.

description: Morphometrics are fundamental for statistical analyses of fossils, particularly because soft parts or DNA are rarely preserved and thus hard parts such as shells are commonly the only source of information. Geometric morphometrics i.e. landmark analysis has been successfully established but exhibits a couple of shortcomings. On the one hand landmarking is rather subjective and on the other hand the application at the level of micro-sculpture is difficult. With the aid of high-resolution 3D scanning technology and analyses of fractal dimensions, we test whether shortcomings of linear and geometric morphometrics can be overcome. As a model group, we selected a clade of modern viviparid gastropods from Lake Lugu, the shells of which show a high degree of sculptural variation. Linear and landmark analyses were applied to the same shells, in order to root the fractal dimensions. The genetic diversity of the gastropod clade was basically assessed. The genetic results suggest that the gastropod clade represents a single species. The results of all morphometric methods applied are in line with the genetic results, which is that no clustering of morpho-types occurs. Apart from this overall agreement, landmark and fractal dimension analyses do not correspond with each other but represent data sets with different information. Generally, the fractal dimension values quantify the roughness of the shell surface, the resolution of the 3D-scans determining the level. In our approach, we captured the micro-sculpture but not the first-order sculptural elements, which explains that fractal dimension and landmark data are not in phase. We can show that analyzing fractal dimensions of gastropod shells opens a window to more detailed information that can be considered in evolutionary and ecological contexts. We propose that using 3D-scans with a low resolution may successfully substitute landmark analyses because it overcomes the subjective landmarking. Analyses of 3D-scans with higher resolution than used in this study will provide surface roughness information at the mineralogical level. We suggest that fractal dimension analyses of a combination of differently resolved 3D-models will significantly improve the quality of shell morphometrics.

description: The effect of missing data on the distances of ichthyosauriform taxa from the morphospace origin. Linear regressions between a taxon’s percentage missing data and its Pythagorean distance from the origin of PCO space on the first two PCO axes. PCO was performed with and without negative eigenvalue correction on raw, Generalised Euclidean (GED), Gower Coefficient (GOW) and Maximum Observable Rescaled (MAX) distance matrices generated from the cladistic matrix of Moon [27].

description: A famous theorem of Hilbert from 1888 states that a positive semidefinite (psd) real form is a sum of squares (sos) of real forms if and only if $n=2$ or $d=1$ or $(n,2d)=(3,4)$, where $n$ is the number of variables and $2d$ the degree of the form. In 1976, Choi and Lam proved the analogue of Hilbert's Theorem for symmetric forms by assuming the existence of psd not sos symmetric $n$-ary quartics for $n \geq 5$. In this paper we complete their proof by constructing explicit psd not sos symmetric $n$-ary quartics for $n \geq 5$.
description: The previous submission has been improved and split into two papers. The first one being the present version and the second one called "The analogue of Hilbert's 1888 theorem for Even Symmetric Forms" in which we completed our conjecture, namely, an even symmetric n-ary 2d-ic psd form is sos if and only if n=2 or d=1 or (n,2d)=(3,8) or (n,2d)=(n,4) for n greater than or equal to 3

description: We consider Markovian multiclass multi-pool networks with heterogeneous server pools, each consisting of many statistically identical parallel servers, where the bipartite graph of customer classes and server pools forms a tree. Customers form their own queue and are served in the first-come first-served discipline, and can abandon while waiting in queue. Service rates are both class and pool dependent. The objective is to study the limiting diffusion control problems under the long run average (ergodic) cost criteria in the Halfin--Whitt regime. Two formulations of ergodic diffusion control problems are considered: (i) both queueing and idleness costs are minimized, and (ii) only the queueing cost is minimized while a constraint is imposed upon the idleness of all server pools. We develop a recursive leaf elimination algorithm that enables us to obtain an explicit representation of the drift for the controlled diffusions. Consequently, we show that for the limiting controlled diffusions, there always exists a stationary Markov control under which the diffusion process is geometrically ergodic. The framework developed in our earlier work is extended to address a broad class of ergodic diffusion control problems with constraints. We show that that the unconstrained and constrained problems are well posed, and we characterize the optimal stationary Markov controls via HJB equations.

description: The mammalian masticatory rhythm is produced by a brainstem timing network. The rhythm is relatively fixed within individual animals but scales allometrically with body mass (Mb) across species. It has been hypothesized that sensory feedback and feed-forward adjust the rhythm to match the jaw's natural resonance frequency, with allometric scaling being an observable consequence. However, studies performed with adult animals show that the rhythm is not affected by jaw mass manipulations, indicating that either developmental or evolutionary mechanisms are required for allometry to become manifest. The present study was performed to tease out the relative effects of development versus natural selection on chewing rate allometry. Thirty-one dog breeds and 31 mass-matched non-domestic mammalian species with a range in Mb from ∼2 kg to 50 kg were studied. Results demonstrated that the chewing rhythm did not scale with Mb among dog breeds (R=0.299, P>0.10) or with jaw length (Lj) (R=0.328, P>0.05). However, there was a significant relationship between the chewing rhythm and Mb among the non-domestic mammals (R=0.634, P<0.001). These results indicate that scaling is not necessary in the adult animal. We conclude that the central timing network and related sensorimotor systems may be necessary for rhythm generation but they do not explain the 1/3rd to 1/4th allometric scaling observed among adult mammals. The rhythm of the timing network is either adjusted to the physical parameters of the jaw system during early development only, is genetically determined independently of the jaw system or is uniquely hard-wired among dogs and laboratory rodents.

description: For this study, we will use actual online sports gambling records to explore the relationships between three loss chasing domains (i.e., stake size, odds, time between bets), including their relationships with each other and with other important gambling behaviors. we will construct high/low dichotomies on each dimension using one-dimensional k-means cluster analysis. Using these dichotomies, we will assess whether, in terms of predicting mounting losses (a proxy of gambling harm), a multidimensional definition of loss chasing is superior to a unidimensional approach.

description: In this work, we investigate inflationary cosmology using scalar field theory deformed by the generalized uncertainty principle (GUP) containing a linear momentum term. Apart from being consistent with the existence of a minimum measurable length scale, this GUP is also consistent with doubly special relativity and hence with the existence of maximum measurable momentum. We use this deformed scalar field theory to analyze the tensor and scalar mode equations in a de Sitter background, and to calculate modifications to the tensor-to-scalar ratio. Finally, we compare our results for the tensor-to-scalar ratio with the Planck data to constrain the minimum length parameter in the GUP.
