description: The intrinsic variability of young active stars is one of the main limitations in detection and characterisation of exoplanets with Doppler spectroscopy. Indeed, stellar activity affects the measurement of radial velocity (RV) often preventing the correct detection of the planet, in particular in presence of fast rotation. We present a method to optimize the RVs extraction based on the cross-correlation function (CCF) technique that takes into account the activity of the star modelled by the presence of one or more spots on the stellar disc. We applied our technique to 146 HARPS-N spectra of V830 Tau and to 106 HARPS spectra of DS Tuc A, two young fast rotating stars. We find that the stars are well modelled by applying One or Two-spots model to the CCFs. We verified that the method removes efficiently part of the rotation signal, and that the new RVs show a significantly lower dispersion with respect to the TERRA pipeline dataset for both targets. We also tested the detection sensitivity of the method by direct injection of a planetary signal into the data and we demonstrated that our method improves significantly the detection sensitivity. The “Spots model” provides us also the physical properties of the spots that results modulated by rotation and with filling factor consistent with values as expected from the literature.

description: The Majorana Collaboration is constructing a system containing 40 kg of HPGe detectors to demonstrate the feasibility and potential of a future tonne-scale experiment capable of probing the neutrino mass scale in the inverted-hierarchy region. To realize this, a major goal of the Majorana Demonstrator is to demonstrate a path forward to achieving a background rate at or below 1 cnt/(ROI-t-y) in the 4 keV region of interest around the Q-value at 2039 keV. This goal is pursued through a combination of a significant reduction of radioactive impurities in construction materials with analytical methods for background rejection, for example using powerful pulse shape analysis techniques profiting from the p-type point contact HPGe detectors technology. The effectiveness of these methods is assessed using simulations of the different background components whose purity levels are constrained from radioassay measurements.

description: Thermalization of a parametrically driven magnon gas leading to the formation of a Bose-Einstein condensate at the bottom of a spin-wave spectrum was studied by time- and wavevector-resolved Brillouin light scattering spectroscopy. It has been found that the condensation is preceded by the conversion of initially pumped magnons into a second group of frequency degenerated magnons, which appear due to parametrically stimulated scattering of the initial magnons to a short-wavelength spectral region. In contrast to the first magnon group, which wavevectors are orthogonal to the wavevectors of the magnons at the lowest energy states, the secondary magnons can effectively scatter to the bottom of the spectrum and condense there.

description: The MAJORANA DEMONSTRATOR will search for neutrinoless-double-beta decay (0νββ) in 76Ge, while establishing the feasibility of a future tonne-scale germanium-based 0νββ experiment, and performing searches for new physics beyond the Standard Model. The experiment, currently under construction at the Sanford Underground Research Facility in Lead, SD, will consist of a pair of modular high-purity germanium detector arrays housed inside of a compact copper, lead, and polyethylene shield. Through a combination of strict materials qualifications and assay, low-background design, and powerful background rejection techniques, the Demonstrator aims to achieve a background rate in the 0νββ region of interest (ROI) of no more than 3 counts in the 0νββ-decay ROI per tonne of target isotope per year (cnts/(ROI-t-y)). The current status of the Demonstrator is discussed, as are plans for its completion.

description: High purity germanium (HPGe) crystals will be used for the MAJORANA DEMONSTRATOR, where they serve as both the source and the detector for neutrinoless double beta decay. It is crucial for the experiment to understand the performance of the HPGe crystals. A variety of crystal properties are being investigated, including basic properties such as energy resolution, efficiency, uniformity, capacitance, leakage current and crystal axis orientation, as well as more sophisticated properties, e.g. pulse shapes and dead layer and transition layer distributions. In this talk, we will present our measurements that characterize the HPGe crystals. We will also discuss the our simulation package for the detector characterization setup, and show that additional information can be extracted from data-simulation comparisons.

pre-main sequence

description: Almost twenty five years ago the variable star, V582 Mon, was re-discovered by Kearns and Herbst and henceforth has also been known as KH 15D. In this poster, I will review the history of this intriguing system, and what it represents: an opportunity to study a pre-main sequence (PMS) binary system still embedded in an accretion disk. The steady precession of the occulting circumbinary (CB) ring has allowed us to derive the stellar properties of both stars, and presents us with the opportunity to refine and expand current models of the system. The latest observations reveal significant structure in the trailing edge.

description: We present an efficient theoretical method for calculating the time evolution of the density matrix of a multilevel quantum system weakly interacting with incoherent light. The method combines the Bloch-Redfield theory with a partial secular approximation for one-photon coherences, resulting in a master equation that explicitly exposes the reliance on transition rates and the angles between transition dipole moments in the energy basis. The modified Bloch-Redfield master equation allows an unambiguous distinction between the regimes of quantum coherent vs. incoherent energy transfer under incoherent light illumination. The fully incoherent regime is characterized by orthogonal transition dipole moments in the energy basis, leading to a dynamical evolution governed by a coherence-free Pauli-type master equation. The coherent regime requires non-orthogonal transition dipole moments in the energy basis, and leads to the generation of noise-induced quantum coherences and population-to-coherence couplings. As a first application, we consider the dynamics of excited state coherences arising under incoherent light excitation from a single ground state, and observe population-to-coherence transfer and the formation of non-equilibrium quasisteady states in the regime of small excited state splitting. Analytical expressions derived earlier for the V-type system [Phys. Rev. Lett. 113, 113601 (2014)] are found to provide a nearly quantitative description of multilevel excited-state populations and coherences in both the small- and large-molecule limits.

description: The model of current-carrying string loop oscillations is tested to explain the special set of frequencies related to the high-frequency quasiperiodic oscillations (HF QPOs) observed recently in the low-mass X-ray binary XTE J1701-407 containing a neutron star. The external geometry of the neutron star is approximated by the Kerr geometry, introducing errors not exceeding $10~\%$ for slowly rotating massive neutron stars. The frequencies of the radial and vertical string loop oscillations are then governed by the mass $M$ and dimensionless spin $a$ of the neutron star, and by the dimensionless parameter $ω$ describing combined effects of the string loop tension and its angular momentum. It is explicitly demonstrated that the string-loop oscillation model can explain the observed kHz frequencies for the neutron star parameters restricted to the intervals ${0.2

description: We propose an approach to detect flying objects such as UAVs and aircrafts when they occupy a small portion of the field of view, possibly moving against complex backgrounds, and are filmed by a camera that itself moves. Solving such a difficult problem requires combining both appearance and motion cues. To this end we propose a regression-based approach to motion stabilization of local image patches that allows us to achieve effective classification on spatio-temporal image cubes and outperform state-of-the-art techniques. As the problem is relatively new, we collected two challenging datasets for UAVs and Aircrafts, which can be used as benchmarks for flying objects detection and vision-guided collision avoidance.

description: We investigate the photocurrent properties of the topological insulator (Bi$_{0.5}$Sb$_{0.5}$)$_2$Te$_3$ on SrTiO$_3$-substrates. We find reproducible, submicron photocurrent patterns generated by long-range chemical potential fluctuations, occurring predominantly at the topological insulator/substrate interface. We fabricate nano-plowed constrictions which comprise single potential fluctuations. Hereby, we can quantify the magnitude of the disorder potential to be in the meV range. The results further suggest a dominating photo-thermoelectric current generated in the surface states in such nanoscale constrictions.

description: This Article provides insights into the question of whether there is a tension between commonness and differentiation in EU policies, in particular post-Brexit. Brexit triggered new discussions on so-called differentiated integration (DI) in the European Union. Not only was Brexit perceived as a potential tool to take further integrative steps in certain policy areas, it also pointed to the idea that there is a risk in trying to force each and every Member State to follow the same pace. Hence, while part of the scholarship sees Brexit as a tragedy for the European integration process, others have pointed to possible advantages that would allow for further integration in certain areas. In any case, the present Special Section underlines that Brexit seems to have renewed the debate on the ways in which the EU Member States could proceed, together or in smaller groups. It takes stock of the DI possibilities in different concrete policy areas and highlights options and obstacles.

description: The MAJORANA DEMONSTRATOR will search for the neutrinoless double beta decay (ββ(0ν)) of the isotope 76Ge with a mixed array of enriched and natural germanium detectors. In view of the next generation of tonne-scale germanium-based ββ(0ν)-decay searches, a major goal of the MAJORANA DEMONSTRATOR is to demonstrate a path forward to achieving a background rate at or below 1 cnt/(ROI-t-y) in the 4 keV region of interest (ROI) around the 2039-keV Q-value of the 76Ge ββ(0ν)-decay. Such a requirement on the background level significantly constrains the design of the readout electronics, which is further driven by noise and energy resolution performances. We present here the low-noise low- background front-end electronics developed for the low-capacitance p-type point contact (P-PC) germanium detectors of the MAJORANA DEMONSTRATOR. This resistive-feedback front-end, specifically designed to have low mass, is fabricated on a radioassayed fused-silica substrate where the feedback resistor consists of a sputtered thin film of high purity amorphous germanium and the feedback capacitor is based on the capacitance between gold conductive traces.

description: Products of random $2\times 2$ matrices exhibit Gaussian fluctuations around almost surely convergent Lyapunov exponents. In this paper, the distribution of the random matrices is supported by a small neighborhood of order $λ>0$ of the identity matrix. The Lyapunov exponent and the variance of the Gaussian fluctuations are calculated perturbatively in $λ$ and this requires a detailed analysis of the associated random dynamical system on the unit circle and its invariant measure. The result applies to anomalies and band edges of one-dimensional random Schrödinger operators.

description: Enhanced cooperation under art. 20 TEU is a tool introduced by the Treaty of Amsterdam to allow a group of at least nine member states to adopt rules of secondary law that binds only these participating States. Introduced as an instrument to tackle problems of a Union of 27 (and more) States, it has only been used on a few occasions. However, its use (and non-use) is not only dependent solely on the number of Union member states. Shifting political attitudes in the member states and - plainly and simply - the legal framework for this tool of differentiate integration influence how and when enhanced cooperation can and will be used as an instrument to overcome deadlocks in negotiation. Against the background of member state practice, the Article sets out to explore the potential of enhanced cooperation.

description: Diffusion of information and viral content, social contagion and influence are still topics of broad evaluation. As theory explaining the role of influentials moves slightly to reduce their importance in the propagation of viral content, authors of the following paper have studied the information epidemic in a social networking platform in order to confirm recent theoretical findings in this area. While most of related experiments focus on the level of individuals, the elementary entities of the following analysis are dyads. The authors study behavioral motifs that are possible to observe at the dyadic level. The study shows significant differences between dyads that are more vs less engaged in the diffusion process. Dyads that fuel the diffusion proccess are characterized by stronger relationships (higher activity, more common friends), more active and networked receiving party (higher centrality measures), and higher authority centrality of person sending a viral message.

Self-similar impulsive capillary waves on a ligament

Subjects: subject: Fluid Dynamics (physics.flu-dyn)

description: We study the short-time dynamics of a liquid ligament, held between two solid cylinders, when one is impulsively accelerated along its axis. A set of one-dimensional equations in the slender-slope approximation is used to describe the dynamics, including surface tension and viscous effects. An exact self-similar solution to the linearized equations is successfully compared to experiments made with millimetric ligaments. Another non-linear self-similar solution of the full set of equations is found numerically. Both the linear and non-linear solutions show that the axial depth at which the liquid is affected by the motion of the cylinder scales like $\sqrt{t}$. The non-linear solution presents the peculiar feature that there exists a maximum driving velocity $U^\star$ above which the solution disappears, a phenomenon probably related to the de-pinning of the contact line observed in experiments for large pulling velocities.

description: We study Cauchy means of Dirichlet polynomials $$\int_\R \Big|\sum_{n=1}^N \frac{1}{ n^{\s+ ist}} \Big|^{2q} \frac{\dd t}{π( t^2+1)}.$$ These integrals were investigated when $q=1,\s= 1, s=1/2 $ by Wilf, using integral operator theory and Widom's eigenvalue estimates. We show the optimality of some upper bounds obtained by Wilf. We also obtain new estimates for the case $q\ge 1$, $\s\ge 0$ and $s>0$. We complete Wilf's approach by relating it with other approaches (having notably connection with Brownian motion), allowing simple proofs, and also prove new results.

description: This Article argues that the legal space for truly structural forms of differentiation in the EU is limited by several sources of rigidity. Sources of rigidity are thereby understood as legal rules and principles that, either by themselves or in interaction with other rules, principles and material facts, limit the scope for structurally significant differentiation in the EU's legal and constitutional set-up. A source of rigidity can therefore be broader than a single legal rule or principle because the rigidity may stem from a combination of or interaction between multiple principles, rules and facts. Using Brexit as a prism, this Article identifies at least three such sources of legal rigidity, being reciprocity, interconnectedness and effectiveness. These sources of rigidity also place significant limits on the possible dynamics of differentiation. It is demonstrated how Brexit brought these sources of rigidity to the surface, and how legal rigidity can and likely will collide with an increasing political desire for more structural differentiation in the future.

description: A new H^- ion source has been installed successfully and will be used to serve the China Spallation Neutron Source (CSNS). In this paper, we report various components of the ion source, including discharge chamber, temperature, cooling system, extraction electrodes, analyzing magnet, remote control system and so on. Compared to the previous experimental ion source, some improvements have been made to make the ion source more compact and convenient. In the present arrangement, the Penning field is generated by a pair of pole tip extensions on the analyzing magnet instead of by a separate circuit. For the remote control system, F3RP61-2L is applied to the accelerator online control system for the first time. In the running of the ion source, a stable pulse H- beam with a current of 50 mA at an energy of 50 keV is produced. The extraction frequency and pulse width is 25 Hz and 500microsecond, respectively. Furthermore, an emittance scanner has been installed and measurements are in progress.

description: Theater has long-standing roots in social justice and holds promise for reducing racist attitudes and behaviors. Objectives of
this study were to (a) collect and theatrically portray narratives from Black occupational therapy students and practitioners
to a national audience and (b) examine the impact of the theatrical performance on anti-Black racism among attendees. The
Identity Development Evolution and Sharing (IDEAS) model guided translation of narratives into a filmed performance. Paired
t-test of pre/post administration of the Acceptance and Action Questionnaire–Stigma (AAQ-S) measured changes in stigma
beliefs. Qualitative thematic analysis of an open-ended post-survey question elucidated experiences of the performance. The
performance engendered significant decreases in stigma; qualitative data elucidated potential mechanisms of change. This
study provides insight into experiences of anti-Black racism within occupational therapy and offers a promising means for
occupational therapists to engage in anti-Black racism.
title: The ‘more-than-food’ geographies of omega-3s
Creators: name: Browne, Danielle
Publisher: name: Memorial University of Newfoundland
Year: 2023

description: Omega-3s are known and understood scientifically from the perspective of a biochemist. From this perspective, it is a polyunsaturated fatty acid, also known as a PUFA. Several well-known benefits are associated with this macronutrient, including heart health, brain health, and early childhood development. However, omega-3s can also be fruitfully considered what Aya Hirata Kimura would call a “charismatic nutrient.” Approaching omega-3s as a charismatic nutrient allows me to reveal controversies and the socio-political networks associated with this important macronutrient. This research aims to examine omega-3s as a charismatic nutrient by focusing on the sociopolitical networks that support this macronutrient. The research is also framed through recent approaches to the geography of food and nutrition. The thesis is organized into 2 chapters. In chapter 2 the focus is on two controversies associated with omega-3s, namely reports on the declining levels of omega-3s in farmed salmon, and reports that farmed salmon also contain toxic chemicals such as methylmercury. The approach in this chapter is controversy mapping, a methodology that allows researchers to bring controversies ‘down to earth’. Key findings include the way a single scientific fact is used by different actor networks, the source of knowledge on farmed salmon nutrition, and the actors that are absent from these networks. While controversy mapping is a key method for brining utterances back down to earth, care must be taken in interpreting some of the results of the analysis. Chapter 3 considers another problem associated with omega-3s, but in this case global deficiencies in this important macronutrient. I examine two proposed solutions to this problem and critically assess them through more-than-food approaches to food geography. The proposed solutions involve shifting land-sea sources of food (Omega-3 World) and improving the efficiency of omega-3 systems (Systems World). Using the more-than-food approaches allows me to critically assess these proposals by revealing what I call the Real World of omega-3s. In this real world of omega-3s the problem of global deficiencies is unlikely to be solved.

description: The "uniformity-based"-model of EU integration has lost considerable ground. It has become more and more considered as a model which takes too little account of national differences in economic, social, cultural and constitutional conditions and in political views. Differentiated integration (DI) raises issues, however. Equality of the Member States and the effectiveness of EU law and policy may be seriously impaired. This Article explores the potential of legislative differentiation as an alternative to more classic forms of DI. With legislative differentiation, we refer to the situation in which Member States are allowed to make substantive policy choices in the implementation of EU legislation and use such flexibility to customize EU legislation to their own domestic contexts. We explore this potential by assessing two case studies: the General Data Protection Regulation and the Child Sexual Abuse Directive. The analysis of these case studies shows that legislative differentiation is a multifaceted phenomenon that indeed has the potential to be an alternative to the classic forms of DI. Yet, in practice sub-optimal results have been found as well. Therefore, more consideration and a better incorporation of diversity in legislative processes is required to further enhance the potential of differentiated legislation.

description: A central goal in quantum information science is to efficiently interface photons with single optical modes for quantum networking and distributed quantum computing. Here, we introduce and experimentally demonstrate a compact and efficient method for the low-loss coupling of a solid-state qubit, the nitrogen vacancy (NV) centre in diamond, with a single-mode optical fibre. In this approach, single-mode tapered diamond waveguides containing exactly one high quality NV memory are selected and integrated on tapered silica fibres. Numerical optimization of an adiabatic coupler indicates that near-unity-efficiency photon transfer is possible between the two modes. Experimentally, we find an overall collection efficiency between 18-40 % and observe a raw single photon count rate above 700 kHz. This integrated system enables robust, alignment-free, and efficient interfacing of single-mode optical fibres with single photon emitters and quantum memories in solids.

description: Historically, the use of differentiated integration mechanisms has been based on the idea of the widening and deepening of the European Union, necessitated by the enlargement of the bloc through the addition of Member State countries. The advent of Brexit means that we are in a rather different situation today, where the monodirectional march towards deeper, uniform integration between an ever increasing number of States is neither inevitable nor assured. The differences between all of the then 28 individual Member States in the pre-Brexit Union were multifarious. These differences have not disappeared along with the UK upon its exit from the Union. They still exist between the remain-ing 27 Member States and will likely increase in prominence as the European Union pursues its future path. Addressing those differences will require an alternative approach to uniform integration from the EU, it will require differentiated integration. This Article suggests that there are lessons to be learnt on differentiated integration from applying Brexit as a framework. The confusion surrounding differentiated integration as a concept, and the prominent role of the UK in availing itself of opportunities to utilise differentiated integration mechanisms, has led differentiated integration to be attributed to the UK as a form of British exceptionalism. Brexit is not just an opt-out but the ultimate opt-out, a form of flexibility sought from outside the European Union, consequent on a lack of wider acceptance of differentiated integration in terms of both legal permissiveness and extent as well as attitude within the Union. The maintenance of differences between the remaining Member States means that there needs to be increased open acceptance of the likely need for greater differentiated integration in the future.
