description: The heat capacity of helical magnets Cu2OSeO3 and MnSi has been investigated at high pressures by the ac-calorimetric technique. Despite the differing nature of their magnetic moments, Cu2OSeO3 and MnSi demonstrate a surprising similarity in behavior of their magnetic and thermodynamic properties at the phase transition. Two characteristic features of the heat capacity at the phase transitions of both substances (peak and shoulder) behave also in a similar way at high pressures if analyzed as a function of temperature. This probably implies that the longitudinal spin fluctuations typical of weak itinerant magnets like MnSi contribute little to the phase transition. The shoulders of the heat capacity curves shrink with decreasing temperature suggesting that they arise from classical fluctuations. In case of MnSi the sharp peak and shoulder at the heat capacity disappear simultaneously probably signifying the existence of a tricritical point and confirming the fluctuation nature of the first order phase transition in MnSi as well as in Cu2OSeO3.

description: We develop a novel technique through spectral decompositions to study the gravitational perturbations of a black hole, without needing to decouple the linearized field equations into master equations and separate their radial and angular dependence. We first spectrally decompose the metric perturbation in a Legendre and Chebyshev basis for the angular and radial sectors respectively, using input from the asymptotic behavior of the perturbation at spatial infinity and at the black hole event horizon. This spectral decomposition allows us to then transform the linearized Einstein equations (a coupled set of partial differential equations) into a linear matrix equation. By solving the linear matrix equation for its generalized eigenvalues, we can estimate the complex quasinormal frequencies of the fundamental mode and various overtones of the gravitational perturbations simultaneously and to high accuracy. We apply this technique to perturbations of a nonspinning, Schwarzschild black hole in general relativity and find the complex quasinormal frequencies of two fundamental modes and their first two overtones. We demonstrate that the technique is robust and accurate, in the Schwarzschild case leading to relative fractional errors of $\leq 10^{-10} - 10^{-8}$ for the fundamental modes, $\leq 10^{-7} - 10^{-6}$ for their first overtones, $\leq 10^{-7} - 10^{-4}$ for their second overtones. This method can be applied to any black hole spacetime, irrespective of its Petrov type, making the numerical technique extremely powerful in the study of black hole ringdown in and outside general relativity.

description: COVID-19 has led to the use of emergency powers that shrink civic space globally. Southeast Asia is no exception. Yet, emergency powers have varying effects in controlling the pandemic and civil societies have also responded to such constraints differently. Moreover, there are few detailed studies that examine the implications of broadened emergency powers for human rights defenders and democracy activists during COVID-19. This policy brief tackles the issue by drawing from two country contexts from Southeast Asia—Thailand and the Philippines. It analyses the influence that emergency powers have in shaping civil society activism. It further compares and contrasts these two countries by highlighting: 1. How emergency powers create diverging outcomes in managing the pandemic. 2. How civil society activism shapes and is shaped by national pandemic response.

description: The thermodynamics of pairing phase-transition in nuclei is studied in the canonical ensemble and treating the pairing correlations in a finite-temperature variation after projection BCS approach (FT-VAP). Due to the restoration of particle number conservation, the pairing gap and the specific heat calculated in the FT-VAP approach vary smoothly with the temperature, indicating a gradual transition from the superfluid to the normal phase, as expected in finite systems. We have checked that the predictions of the FT-VAP approach are very accurate when compared to the results obtained by an exact diagonalization of the pairing Hamiltonian. The influence of pairing correlations on specific heat is analysed for the isotopes $^{161,162}$Dy and $^{171,172}$Yb. It is shown that the FT-VAP approach, applied with a level density provided by mean field calculations and supplemented, at high energies, by the level density of the back-shifted Fermi gas model, can approximate reasonably well the main properties of specific heat extracted from experimental data. However, the detailed shape of the calculated specific heat is rather sensitive to the assumption made for the mean field.

description: Spatial qudits are D-dimensional ($D\geq 2$) quantum systems carrying information encoded in the discretized transverse momentum and position of single photons. We present a proof-of-principle demonstration of a method for preparing arbitrary pure states of such systems by using a single phase-only spatial light modulator (SLM). The method relies on the encoding of the complex transmission function corresponding to a given spatial qudit state onto a preset diffraction order of a phase-only grating function addressed at the SLM. Fidelities of preparation above 94% were obtained with this method, which is simpler, less costly, and more efficient than those that require two SLMs for the same purpose.

description: *Context: The optimisation of new multiplex spectrographs (resolution, wavelength range,...), their associated surveys (choice of setup), or their parameterisation pipelines require methods that estimate which wavelengths contain useful information. *Aim: We propose a method that establishes the usefulness (purity & detectability) of an atomic line. We show two applications: a) optimising an instrument, by comparing the number of useful lines at a given setup, and b) optimising the line-list for a given setup by choosing the least blended lines detectable at different signal-to-noise ratios. *Method: The method compares pre-computed synthetic stellar spectra containing all of the elements and molecules with spectra containing the lines of specific elements alone. Then, the flux ratios between the full spectrum and the element spectrum are computed to estimate the line purities. The method identifies automatically (i) the line's central wavelength, (ii) its detectability based on its depth and a given S/N threshold and (iii) its usefulness based on the purity ratio. *Results: We compare the three WEAVE high-resolution setups (Blue: 404-465nm, Green: 473-545nm, Red: 595-685nm), and find that the Green+Red setup both allows one to measure more elements and contains more useful lines. However, there is a disparity in terms of which elements are detected, which we characterise. We also study the performances of R~20 000 and R~6000 spectra covering the entire optical range. Assuming a purity threshold of 60%, we find that the HR setup contains a much wealthier selection of lines, for any of the considered elements, whereas the LR has a "loss" of 50 to 90% of the lines even for higher S/N. *Conclusions: The method provides a diagnostic of where to focus to get the most out of a spectrograph, and is easy to implement for future instruments, or for pipelines that require line masks.

description: Highly anisotropic "nematically ordered" aerogel induces global uniaxial anisotropy in superfluid 3He. The anisotropy lowers symmetry of 3He in aerogel from spherical to axial. As a result instead of one transition temperature in the state, characterized by the orbital moment l=1 there are two, corresponding to projections l_z=o and l_z=\pm 1. The splitting of transition has a pronounced effect on the phase diagram of superfluid 3He and on a structures of appearing phases. Possible phase diagrams, obtained phenomenologically on a basis of Landau expansion of thermodynamic potential in a vicinity of the transition temperature are presented here. The order parameters, corresponding to each phase and their temperature dependencies are found.

In this paper, we present GCUBE(Geographical Cube) storage and indexing procedure to aggregate the spatial information/Continuous values. We employed the proposed approach storing and indexing using synthetic and real data sets and evaluated its build, update and Query time. It is observed that the proposed procedure offers significant performance advantage.

The non-Gaussianity of this model is considered and the amplitude of the non-Gaussianity is studied in both the equilateral and orthogonal configurations. By taking various functions of the DBI field, inflaton potential and the Gauss-Bonnet coupling term, we test the model with observational data and find some constraints on the Gauss-Bonnet coupling parameter.

Policy Brief: Towards an Inclusive Global Biodiversity Framework

Publisher: name: Zenodo

Subjects: biodiversity conservation, inclusive-conservation, protected areas

description: ENVISION’s contribution towards an inclusive Global Biodiversity Framework. In this brief, we present how the inclusive conservation approach can be helpful in the implementation of both the Post-2020 Global Biodiversity Framework and the EU Biodiversity Strategy for 2030. A unifying challenge for protected area (PA) management is the need to extend and broaden the stewardship of PAs, by including the diverse visions of stakeholders and engaging nearby communities. Using first results emerging from the ENVISION case studies we explore to what extent balancing diverse stakeholder visions is possible, and how strategies based on collectively defined visions can be translated into sustainable protected area management at multiple scales. Different inclusive approaches include assessing multiple visions for protected area management, considering their consequences collectively, defining new visions, and exploring power relations and different governance models. The policy brief aims to demonstrate how the inclusive conservation approach can accommodate and balance different visions for PA management, which is a crucial step towards achieving socially relevant and environmentally sustainable outcomes in PA management.
Measurement of neon in groundwaters: analysis and validation
Creators: name: Martindale Heather
Publisher: name: GNS Science
Year: 2017

description: Nitrate is the most pervasive contaminant in New Zealand’s groundwaters. Thus, understanding and managing nitrogen loads through New Zealand’s aquifers is vital for maintaining the quality of groundwaters and connected surface waters. Denitrification is a natural process that is mediated by the metabolism of aquifer microorganisms and by which dissolved nitrate is reduced eventually to nitrogen gas. However, the extent of denitrification occurring within New Zealand’s groundwater system is largely unknown, because there has historically been no straightforward, reliable and accurate technique to measure it. Calculation of the concentration of excess nitrogen in groundwaters is a promising technique to quantify the amounts of denitrification occurring in the groundwater system. The concentration of dissolved atmospheric nitrogen, according to the recharge conditions of the water, can be established by the measurement of two noble gases, such as neon and argon, that are part of the atmosphere. This enables differentiating the excess nitrogen gas produced via denitrification reactions from atmospherically derived dissolved nitrogen gas. This report details the development and validation of an analytical method to simultaneously measure neon, argon and nitrogen. (auth)

The mu+ are created by bombarding a target with a 9 mA beam of 800 MeV protons. With this proposal delta can be determined with a precision of about 20 (15) degrees in 6 (12) years. In contrast with the DAEdALUS project, only a single source is required and it runs with a duty factor of 100 percent. Therefore 9 mA is the maximum instanteous current, greatly reducing both the technological challenges and the costs.

When the gain-loss coefficient exceeds a critical value $γ_c$, the $\mathcal{PT}$-symmetry becomes spontaneously broken. We calculate $γ_c(N)$ and prove that $γ_c \to 0$ as $N \to \infty$. In the symmetric phase, the periodic array is shown to support $2N$ solitons with different frequencies and polarisations.

title: An Exploration of Peer Support and its Relationship with Employee Mental Wellbeing
title: A Qualitative Study on Commercial Aviation Pilots
titleType: Subtitle
Creators: name: Jarlvik, Sirkka
Publisher: name: Lancaster University
Year: 2022

description: This study has used theory and research on peer support underpinned by shared firsthand experiences (i.e., peerness) on mental health recovery and concepts on social support within an occupational context to inductively explore the following research question: how is occupational peer support (OPS) experienced by commercial aviation pilots (CAPs) in relation to work-related mental wellbeing? Peer support underpinned by peerness based on mental illness has shown to be a crucial form of social support with a unique ability to sustain or increase mental health. However, empirical evidence on peer support underpinned by occupational peerness (i.e., OPS) and its relationship with employee mental wellbeing is limited. To attain a holistic understanding of the meaning of OPS in occupational high-risk environments and CAPs’ experience of OPS in relation to work-related mental wellbeing, Braun and Clarke’s (2006) inductive thematic analysis has been used to analyse data collected through 26 semi-structured interviews with 6 female and 18 male CAPs (gender undisclosed by two participants). Findings reveal CAPs’ experience of OPS as: 1) a specific and irreplaceable form of social support based on psychologically close working relationships derived through shared first-hand occupational experiences; and 2) a form of social support highly dependent on individual differences and work-related experiences to be perceived as adequate protection against profession- and employer-related factors affecting mental wellbeing negatively. Thus, to protect CAPs against work-related mental health issues, commercial operators (COs) within the commercial aviation industry (CAI) are encouraged to support or provide CAPs with individually adapted OPS initiatives designed to support CAPs with work-related factors prone to affect mental wellbeing. As such, this study provides theoretical and practical advice on OPS and its relationship with employee mental wellbeing and urges cooperation between practitioners and researchers striving to support a healthier and more prosperous workforce, regardless of cultural influences on work.

In the present work excitation functions for all the reactions: 249Cf(48Ca,xn)(297-x)118, 250Cf(48Ca,xn)(298-x)118, 251Cf(48Ca,xn)(299-x)118 and 252Cf(48Ca,xn)(300-x)118 have been calculated in the framework of the fusion-by-diffusion model, assuming fission barriers, ground-state masses and shell effects of the superheavy nuclei predicted by Kowal et al. Energy dependence of the effective cross sections for the synthesis of selected new isotopes: (293)118, (294)118, (295)118 and (296)118 is predicted for the particular isotopic composition of the Cf target prepared for the Dubna experiment.

description: Attracting job applicants is a challenging task for entrepreneurial firms. Research has only begun to study factors predicting entrepreneurial firm recruitment success. Still, a large knowledge gap exists on the topic of entrepreneurial firm recruitment. This cumulative dissertation seeks to address this void. It includes five research papers (chapters 3 to 7) that theoretically and empirically contribute to existing literature by analyzing job applicants’ perceptions of entrepreneurial signals, and by exploring the influence of role (in)congruities which might indicate currently overlooked challenges and opportunities for recruiting entrepreneurs. After a summary of the overall findings in chapter 1, the introduction section (chapter 2) provides a brief summary of the individual research papers as well as their main findings and contributions. The five research papers address following research questions: Does organizational attractiveness increase, via perceived authenticity, when entrepreneurs show entrepreneurial leadership? Is this effect particularly pertinent when entrepreneurs fit the demographic stereotype – being a young man? (research paper 1). Does signaling entrepreneurial orientation influence applicants’ attraction to a small firm, and does CEO age moderate this relationship? (research paper 2). Does job candidates’ perceptions of gender and occupational role incongruities (e.g., women leading start-ups) lead to differences in recruiting outcomes for start-ups using active recruitment strategies via social media? (research paper 3). What do potential employees think how a typical entrepreneurial leader behaves and looks like? (research paper 4). Does the intersection of social categories such as gender, ethnicity, and occupational roles influence human resource acquisition of new ventures? (research paper 5). This dissertation provides new insights and perspectives related to entrepreneurial firm recruitment, and primarily contributes to research at the intersection of entrepreneurship, leadership, and recruitment.

description: In recent years an increasing number of devices and experiments are shown to be limited by mechanical thermal noise. In particular sub-Hertz laser frequency stabilization and gravitational wave detectors, that are able to measure fluctuations of 1E-18 m/rtHz or less, are being limited by thermal noise in the dielectric coatings deposited on mirrors. In this paper we present a new measurement of thermal noise in low absorption dielectric coatings deposited on micro-cantilevers and we compare it with the results obtained from the mechanical loss measurements. The coating thermal noise is measured on the widest range of frequencies with the highest signal to noise ratio ever achieved. In addition we present a novel technique to deduce the coating mechanical losses from the measurement of the mechanical quality factor which does not rely on the knowledge of the coating and substrate Young moduli. The dielectric coatings are deposited by ion beam sputtering. The results presented here give a frequency independent loss angle of (4.70 $\pm$ 0.2)x1E-4 with a Young's modulus of 118 GPa for annealed tantala from 10 Hz to 20 kHz. For as-deposited silica, a weak frequency dependence (~ f^{-0.025}) is observed in this frequency range, with a Young's modulus of 70 GPa and an internal damping of (6.0 $\pm$ 0.3)x1E-4 at 16 kHz, but this value decreases by one order of magnitude after annealing and the frequency dependence disappears.

description: We give a short and elementary proof of an inverse Bernstein-type inequality found by S. Khrushchev for the derivative of a polynomial having all its zeros on the unit circle. The inequality is used to show that equally-spaced points solve a min-max-min problem for the logarithmic potential of such polynomials. Using techniques recently developed for polarization (Chebyshev-type) problems, we show that this optimality also holds for a large class of potentials, including the Riesz potentials $1/r^s$ with $s>0.$

description: Mitochondria are essential adenosine triphosphate (ATP)-generating cellular organelles. In the retina, they are highly numerous in the photoreceptors and retinal pigment epithelium (RPE) due to their high energetic requirements. Fission and fusion of the mitochondria within these cells allow them to adapt to changing demands over the lifespan of the organism. Using transmission electron microscopy, we examined the mitochondrial ultrastructure of zebrafish photoreceptors and RPE from 5 days post fertilisation (dpf) through to late adulthood (3 years). Notably, mitochondria in the youngest animals were large and irregular shaped with a loose cristae architecture, but by 8 dpf they had reduced in size and expanded in number with more defined cristae. Investigation of temporal gene expression of several mitochondrial-related markers indicated fission as the dominant mechanism contributing to the changes observed over time. This is likely to be due to continued mitochondrial stress resulting from the oxidative environment of the retina and prolonged light exposure. We have characterised retinal mitochondrial ageing in a key vertebrate model organism, that provides a basis for future studies of retinal diseases that are linked to mitochondrial dysfunction.

description: In this paper, we introduce a denoising diffusion algorithm to discover microstructures with nonlinear fine-tuned properties. Denoising diffusion probabilistic models are generative models that use diffusion-based dynamics to gradually denoise images and generate realistic synthetic samples. By learning the reverse of a Markov diffusion process, we design an artificial intelligence to efficiently manipulate the topology of microstructures to generate a massive number of prototypes that exhibit constitutive responses sufficiently close to designated nonlinear constitutive responses. To identify the subset of microstructures with sufficiently precise fine-tuned properties, a convolutional neural network surrogate is trained to replace high-fidelity finite element simulations to filter out prototypes outside the admissible range. The results of this study indicate that the denoising diffusion process is capable of creating microstructures of fine-tuned nonlinear material properties within the latent space of the training data. More importantly, the resulting algorithm can be easily extended to incorporate additional topological and geometric modifications by introducing high-dimensional structures embedded in the latent space. The algorithm is tested on the open-source mechanical MNIST data set. Consequently, this algorithm is not only capable of performing inverse design of nonlinear effective media but also learns the nonlinear structure-property map to quantitatively understand the multiscale interplay among the geometry and topology and their effective macroscopic properties.

description: Image forgery localization aims to identify forged regions by capturing subtle traces from high-quality discriminative features. In this paper, we propose a Transformer-style network with two feature extraction branches for image forgery localization, and it is named as Two-Branch Transformer (TBFormer). Firstly, two feature extraction branches are elaborately designed, taking advantage of the discriminative stacked Transformer layers, for both RGB and noise domain features. Secondly, an Attention-aware Hierarchical-feature Fusion Module (AHFM) is proposed to effectively fuse hierarchical features from two different domains. Although the two feature extraction branches have the same architecture, their features have significant differences since they are extracted from different domains. We adopt position attention to embed them into a unified feature domain for hierarchical feature investigation. Finally, a Transformer decoder is constructed for feature reconstruction to generate the predicted mask. Extensive experiments on publicly available datasets demonstrate the effectiveness of the proposed model.

description: AI4DM is a practical and pragmatic suite of critical thinking tools enabling cross-organisational stakeholders to implement transdisciplinary ethical and governance assessments of planned or existing AI and automated decision-making systems. It naturally fosters participation, bringing people together to map AI systems, existing and proposed, against the organisation’s own mission, vision, values and ethics. It uses a whole systems approach to analyse organisational structures and operations, illuminating to participants the breadth of issues beyond their individual responsibilities. The tools are intuitive, practical and can be used for: revealing where and how a system is either in alignment, and where it is (or could be) misaligned with the organisation’s mission, vision, values and ethics; enabling different stakeholders to appreciate where and how their obligations and responsibilities intersect with those of others. emphasising the collective nature of lawful and ethical responsibilities across the whole organisation providing a mechanism for a deep analysis of complex challenges. The toolkit was conceived, created and designed by Giles Lane with illustrations by Alice Angus. It was commissioned by Ansgar Koene at EY Global Services.

description: In this work we characterize the escape of orbits from the phase space of the Riemann-Liouville (RL) fractional standard map (fSM). The RL-fSM, given in action-angle variables, is derived from the equation of motion of the kicked rotor when the second order derivative is substituted by a RL derivative of fractional order $α$. Thus, the RL-fSM is parameterized by $K$ and $α\in(1,2]$ which control the strength of nonlinearity and the fractional order of the RL derivative, respectively. Indeed, for $α=2$ and given initial conditions, the RL-fSM reproduces Chirikov's standard map. By computing the survival probability $P_{\text{S}}(n)$ and the frequency of escape $P_{\text{E}}(n)$, for a hole of hight $h$ placed in the action axis, we observe two scenarios: When the phase space is ergodic, both scattering functions are scale invariant with the typical escape time $n_{\text{typ}}=\exp\langle \ln n \rangle \propto (h/K)^2$. In contrast, when the phase space is not ergodic, the scattering functions show a clear non-universal and parameter-dependent behavior.

description: Intelligence is a critical tool in modern security operations that provides insight into current and future operational conditions. It is a concept that transfers to other applications where monitoring activities or situations is imperative, such as ecological research. As technological advances in the past decades lead to increased availability of potential intelligence, we concentrate on source selection to ensure the resulting intelligence is of high quality and fit for purpose. We wish to bring focus to the more varied nature of intelligence than what is currently reflected in models of its collection and evaluation. Therefore, we examine the intelligence collection and analysis process in two separate scenarios; one treats it as a ongoing strategic activity, in another intelligence collection is carried out with an investigative intent. The first problem we formulate concerns source selection with a random time delay in feedback, corresponding to the collection and evaluation time of the intelligence. Both the distributions of such time delay and the outcome of the intelligence evaluation are unknown, giving rise to the classic exploration-exploitation dilemma in a long-run setting. We develop promising approaches to accommodate the novel features of the model based on Gittins indices and the knowledge gradient, and examine the issues presented when incorporating structures of dependence between the time delay and the outcome of the evaluation. Next, we develop a novel intelligence collection problem rooted in tactical level source selection, aiming to piece together an intelligence picture comprised of multiple types of information, for example, where and when an attack is planned. We demonstrate that when all elements of the model are known, dynamic programming provides the optimal policy. When some elements are unknown, which introduces an exploration-exploitation aspect to the model, we find that in certain cases the ability to learn is severely limited.

description: In the actively coupled ($\mathcal{AC}$) pair of waveguides, the growth of small perturbations is saturated by the focussing nonlinearity that couples the linearly growing to the linearly damped mode. On the other hand, in the $\mathcal{PT}$-symmetric coupler, the focussing nonlinearity promotes the blowup of stationary light beams. The purpose of this study is to compare the nonlinear dynamics and explain the opposite effect of the same nonlinearity in the two systems. We show that while the blowup regimes are stable in the $\mathcal{PT}$-symmetric pair of waveguides, they are unstable and hence cannot be observed in the $\mathcal{AC}$-dimer.

description: Alkynes represent a significant motif in natural products and pharmaceutical drugs, and the wide variety of reactions they can undergo makes them a handy tool in total synthesis. They can be introduced readily in various manners, including via propargylations of ketones and aldehydes. However, one reaction that remains to be examined is the propargylation of oximes to give a propargyl hydroxylamine. Current enantioselective propargylations of oximes typically require a chiral auxiliary and/or rare metals such as palladium or indium. Having an enantioselective propargylation of oximes which could use an external ligand and more commonly available metals would facilitate use of the product in total synthesis, as well as potentially as an unnatural amino acid. Unusual amino acids including alkynes are desirable for their use in copper(I)-catalyzed azide-alkyne [3+2] dipolar cycloadditions, a common bioorthogonal reaction.

Herein, the development of a copper-catalyzed propargylation of oxime esters is described. Initial efforts to induce enantioselectivity using a zinc nucleophile-based system proved fruitless. Although some Lewis acids could raise the yield, the enantioselectivity remained very low. Therefore, new reaction conditions using a boronate nucleophile were investigated. The use of a copper catalyst with a diphosphine ligand gave the desired product in high enantioselectivity, albeit low yield.
