description: The mass-radius relations for white dwarf stars are investigated by solving the Newtonian as well as Tolman-Oppenheimer-Volkoff (TOV) equations for hydrostatic equilibrium assuming the electron gas to be non-interacting. We find that the Newtonian limiting mass of $1.4562M_\odot$ is modified to $1.4166M_\odot$ in the general relativistic case for $^4_2$He (and $^{12}_{\ 6}$C) white dwarf stars. Using the same general relativistic treatment, the critical mass for $^{56}_{26}$Fe white dwarf is obtained as $1.2230M_\odot$. In addition, departure from the ideal degenerate equation of state (EoS) is accounted for by considering Salpeter's EoS along with the TOV equations yielding slightly lower values for the critical masses, namely $1.4081M_{\odot}$ for $^4_2$He, $1.3916M_{\odot}$ for $^{12}_{\ 6}$C and $1.1565M_{\odot}$ for $^{56}_{26}$Fe white dwarfs. We also compare the critical densities for gravitational instability with the neutronization threshold densities to find that $^4_2$He and $^{12}_{\ 6}$C white dwarf stars are stable against neutronization with the critical values of $1.4081M_\odot$ and $1.3916M_{\odot}$, respectively. However the critical masses for $^{16}_{\ 8}$O, $^{20}_{10}$Ne, $^{24}_{12}$Mg, $^{28}_{14}$Si, $^{32}_{16}$S and $^{56}_{26}$Fe white dwarf stars are lower due to neutronization. Corresponding to their central densities for neutronization thresholds, we obtain their maximum stable masses due to neutronization by solving the TOV equation coupled with the Salpeter EoS.

description: We present the magnetically shielded room (MSR) for the n2EDM experiment at the Paul Scherrer Institute which features an interior cubic volume with each side of length 2.92m, thus providing an accessible space of 25m3. The MSR has 87 openings up to 220mm diameter to operate the experimental apparatus inside, and an intermediate space between the layers for sensitive signal processing electronics. The characterization measurements show a remanent magnetic field in the central 1m3 below 100pT, and a field below 600pT in the entire inner volume, up to 4\,cm to the walls. The quasi-static shielding factor at 0.01\,Hz measured with a sinusoidal 2muT peak-to-peak signal is about 100,000 in all three spatial directions and rises fast with frequency to reach 10^8 above 1Hz.

description: Imaging through scattering media is a longstanding issue in a wide range of applications, including biomedicine, security, and astronomy. Speckle-correlation imaging is promising for non-invasively seeing through scattering media by assuming shift-invariance of the scattering process called the memory effect. However, the memory effect is known to be severely limited when the medium is thick. Under such a scattering condition, speckle-correlation imaging is not practical because the correlation of the speckle decays, reducing the field of view. To address this problem, we present a method for expanding the field of view of single-shot speckle-correlation imaging by extrapolating the correlation with a limited memory effect. We derive the imaging model under this scattering condition and its inversion for reconstructing the object. Our method simultaneously estimates both the object and the decay of the speckle correlation based on the gradient descent method. We numerically and experimentally demonstrate the proposed method by reconstructing point sources behind scattering media with a limited memory effect. In the demonstrations, our speckle-correlation imaging method with a minimal lensless optical setup realized a larger field of view compared with the conventional one. This study will make techniques for imaging through scattering media more practical in various fields.

Feeling Social Change in the Gut: Gyāstrik and the Problematisation of Domestic Roles Among Newar Women in Contemporary Nepal

description: Drawing upon 15 months of research conducted in 2018–2019 in Bhaktapur, Nepal, this paper examines how middle-class women experience and make sense of gyāstrik (an umbrella term for multiple gut disorders) as an embodiment of social change. Enumerating dietary injustices and distress following unmet middle-class expectations of well-being and domestic intimacy as a primary cause of the condition, these women narratively problematised social norms and found ways out through the concomitant vocalisation of physical pain and social discontent. While illness epistemologies differ (with the persistence of mind-body dichotomies on the one hand and the centrality of notions of well-being and ideals of self-care on the other), these accounts demonstrate both a passive and active role of the gut in the social change experience, inviting to take the gut as the site where somatic modes of ‘attention’ and ‘action’ enable the navigation of personal life trajectories and the negotiation of social change itself.

description: We study pre-supernova feedback in a sample of $\sim$ 4700 HII regions in the nearby spiral galaxy M83, identified on their H$α$ emission. We pectroscopically identify Wolf-Rayet (WR) stars populating the star-forming regions. For each HII region, we compute the pressure of ionised gas ($P_{\rm ion}$) and the direct radiation pressure ($P_{\rm dir}$) acting in the region, and investigate how they vary with galactocentric distance, with the physical properties of the region, and with the pressure of the galactic environment ($P_\mathrm{DE}$). For a subset of $\sim$ 500 regions, we also investigate the link between the pressure terms and the properties of the cluster population (age, mass, and LyC flux). We find that $P_{\rm ion}$ dominates over $P_{\rm dir}$ by at least a factor of 10 on average over the disk. Both pressure terms are strongly enhanced and become almost comparable in the central starburst region. In the disk ($R \geq 0.15~R_e$), we observe that $P_{\rm dir}$ stays approximately constant with galactocentric distance. $P_{\rm dir}$ is positively correlated with an increase in radiation field strength (linked to the negative metallicity gradient in the galaxy), while it decreases in low extinction regions. $P_{\rm ion}$ decreases constantly for increasing galactocentric distances. In general, we observe that HII regions near the center are underpressured with respect to their surroundings, whereas regions in the disk are overpressured and hence expanding. We find that regions hosting younger clusters or having more mass in young star clusters have a higher internal pressure, indicating that clustered star formation is likely playing a dominant role in setting the pressure. Finally, we estimate that only 13 % of HII regions hosting young clusters and WR stars have $f_{\rm esc} \geq 0$.[Abridged]

description: Low-energy electrons (30-250 eV) have been successfully employed for imaging individual biomolecules. The most simple and elegant design of a low-energy electron microscope for imaging biomolecules is a lensless setup that operates in the holographic mode. In this work we address the problem associated with the reconstruction from the recorded holograms. We discuss the twin image problem intrinsic to inline holography and the problem of the so-called biprism-like effect specific to low-energy electrons. We demonstrate how the presence of the biprism-like effect can be efficiently identified and circumvented. The presented sideband filtering reconstruction method eliminates the twin image and allows for reconstruction despite the biprism-like effect, which we demonstrate on both, simulated and experimental examples.

Distribution of the largest root of a matrix for Roy's test in multivariate analysis of variance

description: Let ${\bf X, Y} $ denote two independent real Gaussian $\mathsf{p} \times \mathsf{m}$ and $\mathsf{p} \times \mathsf{n}$ matrices with $\mathsf{m}, \mathsf{n} \geq \mathsf{p}$, each constituted by zero mean i.i.d. columns with common covariance. The Roy's largest root criterion, used in multivariate analysis of variance (MANOVA), is based on the statistic of the largest eigenvalue, $Θ_1$, of ${\bf{(A+B)}}^{-1} \bf{B}$, where ${\bf A =X X}^T$ and ${\bf B =Y Y}^T$ are independent central Wishart matrices. We derive a new expression and efficient recursive formulas for the exact distribution of $Θ_1$. The expression can be easily calculated even for large parameters, eliminating the need of pre-calculated tables for the application of the Roy's test.

Subjects: subject: High Energy Physics - Phenomenology (hep-ph)

description: In this paper, axion models supplemented by leptoquarks and diquarks are systematically analyzed. Turning on some couplings to and among these latter states permits to unify the Peccei-Quinn symmetry with baryon (B) and lepton (L) numbers, such that the axion becomes associated to the spontaneous breaking of the three $U(1)$ symmetries. All possible four- and six-fermion patterns of B and L violation are discussed, including those inducing proton decay, with $ΔB = 1$ and $ΔL = \pm 1, \pm 3$, neutron-antineutron oscillations with $ΔB = 2$, and Majorana neutrino masses with $ΔL = 2$. Scenarios in which one or two axion fields necessarily appear in any B and/or L violating operators are also constructed. Nucleon decays would then necessarily involve an axion in the final state, while neutron-antineutron oscillations would only happen in an axionic background. This could have implications for the neutron lifetime puzzle, and more generally, opens the door to new phenomenological and cosmological applications.

description: Superconducting circuits are a leading platform for quantum computing. However, their coherence times are still limited and exhibit temporal fluctuations. Those phenomena are often attributed to the coupling between qubits and material defects that can be well described as an ensemble of two-level systems (TLSs). Among them, charge fluctuators inside amorphous oxide layers contribute to both low-frequency $1/f$ charge noise and high-frequency dielectric loss, causing fast qubit dephasing and relaxation. Moreover, spectral diffusion from mutual TLS interactions varies the noise amplitude over time, fluctuating the qubit lifetime. Here, we propose to mitigate those harmful effects by engineering the relevant TLS noise spectral densities. Specifically, our protocols smooth the high-frequency noise spectrum and suppress the low-frequency noise amplitude via depolarizing and dephasing the TLSs, respectively. As a result, we predict a drastic stabilization in qubit lifetime and an increase in qubit pure dephasing time. Our detailed analysis of feasible experimental implementations shows that the improvement is not compromised by spurious coupling from the applied noise to the qubit.

description: Data Discréte or Data and Art: A Black-and-White View (Remembering Halim El-Dabh and Jenny Holzer) The table was a response to the dataism manifesto:

 From Dada to Data One hundred years ago, at the time of the Dada movement, the earth was home to some 1.8 billion people. The counter now stands at over 7 billion. This explosive growth of the world population has clear consequences for society. For the more people there are, the more ideas, the more knowledge, the more things — the more data! But views diverge on what ‘data’ actually means. There is something ambiguous about data: on the one hand it represents actual facts, what we know for sure; but at the same time it forms a kind of intangible reality that hides in ‘the cloud’, as we say nowadays. Because we cannot see this cloud and therefore can’t really get a grip on the data concealed there, the whole atmosphere surrounding data becomes rather mysterious. We are data. The past is data, the future will become data. Data is order and data is chaos. That data triggers our imagination is a good reason to link data to Dada. And then it’s not just the linguistic similarity that reinforces this connection; it’s also the realisation that both Dada and Data are impermanent. We know that Dada had a strong connection with art, that it was a non-movement that occurred at the start of the systems driven world we inhabit today, surrounded by computers. And we know that Data is a consequence of that systems driven world. Dada wanted to derail the march of progress and to forget about the past. Data proclaims a future so massive that we can no longer say with certainty that humans will remain the most important beings on earth. In 30 years’ time we’ll have
 2 billion people more, with all their things and images, or data. And what about art? What is the future of art? The human being is merging with the systems it created, and that process might well turn out to be the biggest work of art ever. We are Data. This post presents a provocative manifesto that primarily challenges our creativity. After all, in 2016 we are still normal people with creative minds who like to express their own style, their own languages and fantasies, opinions and ideas. Although the influence of the systems has become palpable in artistic circles and networks, the artists, writers, thinkers and designers who contributed to this magazine seek to cling to their autonomy. They demonstrate the first manifestations of the merging of man and systems, but also point out interesting crashes and glitches; bumps in the road that can transform into artistic highlights. For now, we juxtapose the raw chunky data with facts and lists. The data contained in this magazine were conceived, processed and copied by people.
 For people make data, and data makes people. We are Data."

description: The Yarkovsky effect plays an important role in the motions of small celestial bodies. Increasingly improving observations bring the need of high-accuracy modelling of the effect. Using a multiphysics software COMSOL, we model the diurnal Yarkovsky effect in three dimensions and compare the results with that derived from the widely adopted theoretical linear model. We find that the linear model presents a high accuracy for spherical asteroids in most cases. The ranges of parameters in which the relative error of the linear model is over 10\% are explored. For biaxial ellipsoidal asteroids (particularly oblate ones), the linear model systematically overestimates the transverse Yarkovsky force by $\sim$10\%. The diurnal effect on triaxial ellipsoids is periodic for which no linear model is available. Our numerical calculations show that the average effects on triaxial ellipsoids are stronger than that on biaxial ellipsoids. We also investigate the diurnal effect on asteroids of real shapes and find it be overestimated by the linear model averagely by 16\%, with a maximum up to 35\%. To estimate the strength of Yarkovsky effect directly from the shape, we introduce a quantity "effective area" for asteroids of any shapes, and find a significant linear relationship between the Yarkovsky migration rate and the effective area. This brings great convenience to the estimation in practice.

description: The detection of the first exoplanet paved the way into the era of transit photometry space missions with a revolutionary photometric precision that aim at discovering new exoplanetary systems around different types of stars. With this high precision, it is possible to derive very accurately the radii of exoplanets which is crucial for constraining their type and composition. However, it requires an accurate description of host stars, especially their center-to-limb variation of intensities (so called limb darkening) as it affects the planet-to-star radius ratio determination. We aim at improving the accuracy of limb darkening calculations for stars with a wide range of fundamental parameters. We used the recently developed 1D MPS-ATLAS code to compute model atmosphere structures and to synthesize stellar limb darkening on a very fine grid of stellar parameters. For the computations we utilized the most accurate information on chemical element abundances and mixing length parameters including convective overshoot. The stellar limb darkening was fitted using the two most accurate limb darkening laws: the power-2 and 4-parameters non-linear laws. We present a new extensive library of stellar model atmospheric structures, the synthesized stellar limb darkening curves, and the coefficients of parameterized limb-darkening laws on a very fine grid of stellar parameters in the Kepler, TESS, CHEOPS, and PLATO passbands. The fine grid allows overcoming the sizable errors introduced by the need to interpolate. Our computations of solar limb darkening are in a good agreement with available solar measurements at different view angles and wavelengths. Our computations of stellar limb darkening agree well with available measurements of Kepler stars. A new grid of stellar model structures, limb darkening and their fitted coefficients in different broad filters is provided in CDS.

description: ABSTRACT: Capt (E) John W. Mason Royal Canadian Navy Royal Canadian Naval Volunteer Reserve Capt. Mason joined the navy in February 1943 as a second class stoker and underwent training as prospective Engine Room Artificer (E.R.A.) in a seven month course at Guelph, Ont. Describes his very early naval days at the Canadian National Exhibition buildings in Toronto. Returns to training at Galt, mostly in the machine shop, and later in Toronto where they trained on internal combustion engines. Finally to Halifax -- poor quarters and food. Describes going ashore in Halifax. Intensive training and a little sea-time in HMCS Niagara (former U.S. destroyer). Formed part of the crew of a frigate (No. 29) then building, but in the meantime was held at HMCS Hochelaga II in Montreal where he was permanent "Captain of the Heads"! Finally sent to HMCS Fort Erie at Quebec City. Work-up in Bermuda. Served six months as a First Class Stoker then an E.R.A. fourth class. Fort Erie was on a local escort for a long period. Returned to Halifax when war ended, with navigation lights burning -- remembers the novelty. Discussed his uniform, pay -- as a first class Stoker, $1.45/day and when he became a petty officer, an E.R.A. fourth class, $3.05/day. Felt himself rich. Comments on the mess-deck and the crowded conditions. Where the leading seaman and the largest of the crew ruled, and where the food was, at best, mediocre. Posted to HMCS Antigonish, re-fitting n Pictou, N.S. After two trips to Bermuda returning soldiers to Halifax he was released in December 1945. Using his D.V.A. credits he returned to university and obtained a degree in mechanical engineering in 1949. The same year he applied to re-join the navy as an Engineer Officer. Sent to the RN for training at HMS Thunderer, the RN Engineering College including four months of hands-on training at John Brown's shipyard on the Clyde. Appointed to the cruiser HMS Kenya, in Japan at that time. A long trip via troop-ship, Hong Kong, and eventually Sasebo, Japan. Speaks very favourably of his time in the Royal Navy. He learned to be a Naval Officer, gain self confidence, self respect, and how to handle men.

description: The software engineering is a relatively new discipline compared to other sciences, since the origins of the term itself dates back to the years 1968 and 1969. At present, the market and the software industry have a significant relevance in several countries of the world; however, although Mexico is immersed in this race, has not even reached the level of success achieved in other countries in this sector. This paper presents an overview of the situation that keeps the practice of software engineering in Mexico, with emphasis on the academic realm. It shows a compilation of scientific research activity carried out in universities, as well as a brief analysis of undergraduate educational programs including the software engineering discipline . At the end, future work to be done is proposed in order to find a point of convergence between academia and industry, and also to support the flourishing of this business which somehow will have a positive impact on the economy of our country.

description: We report on the results of theoretical simulations of the electron channeling in a bent silicon crystal. The dynamics of ultra-relativistic electrons in the crystal is computed using the newly developed part [1] of the MBN Explorer package [2,3], which simulates classical trajectories of in a crystalline medium by integrating the relativistic equations of motion with account for the interaction between the projectile and crystal atoms. A Monte Carlo approach is employed to sample the incoming electrons and to account for thermal vibrations of the crystal atoms. The electron channeling along Si(110) crystallographic planes are studied for the projectile energies 195--855 MeV and different curvatures of the bent crystal.

description: Several rare-earth transition-metal ferrimagnetic systems exhibit all-optical magnetization switching upon excitation with a femtosecond laser pulse. Although this phenomenon is very promising for future opto-magnetic data storage applications, the role of non-local spin transport in these systems is scarcely understood. Using Co/Gd and Co/Tb bilayers we isolate the contribution of the rare-earth materials to the generated spin currents by using the precessional dynamics they excite in an adjacent ferromagnetic layer as a probe. By measuring THz standing spin-waves as well as GHz homogeneous precessional modes, we probe both the high- and low-frequency components of these spin currents. The low-frequency homogeneous mode indicates a significant contribution of Gd to the spin current, but not from Tb, consistent with the difficulty in achieving all-optical switching in Tb-containing systems. Measurements on the THz frequency spin waves reveal the inability of the rare-earth generated spin currents to excite dynamics at the sub-ps timescale. We present modelling efforts using the $s$-$d$ model, which effectively reproduce our results and allow us to explain the behavior in terms of the temporal profile of the spin current.

title: An investigation into the benefits of musical training on cognitive control and emotional processing abilities
Creators: name: Fisher, Nina K.
Publisher: name: University of St Andrews
Year: 2018

description: Evidence suggests that engagement in musical activity may confer cognitive control advantages though it is not clear why this may be. Here it was explored why such advantages may be observed, exploring a potential underlying mechanism which may be responsible for these enhancements using EEG, behavioural, and self-rating methods. Chapters two and three were unable to replicate previous research which report an association between musical training and enhanced cognitive control, though the results suggest that musical training may heighten emotional responses to errors. Considering that musical performance and training involves active, frequent, and repeated engagement with emotional material, chapters four and five aimed to investigate whether musical training can lead to enhancements in emotional processing abilities using a variety of questionnaires and behavioural tasks. Chapter four found significant associations between musical training and enhanced emotional sound recognition accuracy and empathic abilities, although these effects were not replicated in the subsequent chapter, which detected only similar numerical trends. Chapter six was carried out to investigate if the potential association between musical training and enhanced empathy could be observed in a larger and more diverse sample. Furthermore, activities which use similar higher order processes were included to investigate if they could confer the same potential advantages. This study again failed to find a relationship between musical training and enhanced empathy, though dance and sport were significant predictors of higher empathy levels. Considering that all studies reported in this thesis are cross-sectional, these fragile results could be partially due to individual differences between groups and studies. In sum, the results of this thesis provide limited evidence that musical training may enhance specific emotional processing abilities and affective responses to errors which may lead to both enhanced cognitive control, and improved social awareness and interactions with others.

description: We introduce the TangoSIDM project, a suite of cosmological simulations of structure formation in a $Λ$-Self-Interacting Dark Matter (SIDM) universe. TangoSIDM explores the impact of large dark matter (DM) scattering cross sections over dwarf galaxy scales. Motivated by DM interactions that follow a Yukawa potential, the cross section per unit mass, $σ/m_χ$, assumes a velocity dependent form that avoids violations of current constraints on large scales. We demonstrate that our implementation accurately models not only core formation in haloes, but also gravothermal core collapse. For central haloes in cosmological volumes, frequent DM particle collisions isotropise the particles orbit, making them largely spherical. We show that the velocity-dependent $σ/m_χ$ models produce a large diversity in the circular velocities of satellites haloes, with the spread in velocities increasing as the cross sections reach 20, 60 and 100 cm$^2$/g in $10^9~\rm{M}_{\odot}$ haloes. The large variation in the haloes internal structure is driven by DM particles interactions, causing in some haloes the formation of extended cores, whereas in others gravothermal core collapse. We conclude that the SIDM models from the Tango project offer a promising explanation for the diversity in the density and velocity profiles of observed dwarf galaxies.

Quantum Spin-$1$ Anisotropic Ferromagnetic Heisenberg Model in a Crystal Field: A Variational Approach

description: A variational approach based on Bogoliubov inequality for the free energy is employed in order to treat the quantum spin-$1$ anisotropic ferromagnetic Heisenberg model in the presence of a crystal field. Within the Bogoliubov scheme an improved pair approximation has been used. The temperature dependent thermodynamic functions have been obtained and provide much better results than the previous simple mean-field scheme. In one dimension, which is still non-integrable for quantum spin-$1$, we get the exact results in the classical limit, or near-exact results in the quantum case, for the free energy, magnetization and quadrupole moment, as well for the transition temperature. In two and three dimensions the corresponding global phase diagrams have been obtained as a function of the parameters of the Hamiltonian. First-order transition lines, second-order transition lines, tricritical and tetracritical points, and critical endpoints have been located through the analysis of the minimum of the Helmholtz free energy and a Landau like expansion in the approximated free energy. Only first-order quantum transitions have been found at zero temperature. Limiting cases, such as isotropic Heisenberg, Blume-Capel and Ising models have been analyzed and compared to previous results obtained from other analytical approaches as well as from Monte Carlo simulations.

description: When water is confined to nanocavities, its quantum-mechanical behavior can be revealed by terahertz spectroscopy. We place H2O molecules in the nanopores of a beryl crystal-lattice and observe a rich and highly anisotropic set of absorption lines in the terahertz spectral range. Two bands can be identified, which originate from translational and librational motions of the water molecule isolated within the cage; they correspond to the analogous broad bands in liquid water and ice. In the present case of well-defined and highly symmetric nanocavities, the observed fine structure can be explained by macroscopic tunneling of the H2O molecules within a six-fold potential caused by the interaction of the molecule with the cavity walls.

description: A search for supersymmetric partners of top quarks decaying as $\tilde{t}_1\rightarrow c\tilde{\chi}_1^0$ and supersymmetric partners of charm quarks decaying as $\tilde{c}_1\rightarrow c\tilde{\chi}_1^0$, where $\tilde{\chi}_1^0$ is the lightest neutralino, is presented. The search uses 36.1 fb$^{-1}$ $pp$ collision data at a centre-of-mass energy of 13 TeV collected by the ATLAS experiment at the Large Hadron Collider and is performed in final states with jets identified as containing charm hadrons. Assuming a 100% branching ratio to $c\tilde{\chi}_1^0$, top and charm squarks with masses up to 850 GeV are excluded at 95% confidence level for a massless lightest neutralino. For $m_{\tilde{t}_1,\tilde{c}_1}-m_{\tilde{\chi}_1^0} < 100$ GeV, top and charm squark masses 1 up to 500 GeV are excluded.

description: Recent discoveries of highly dispersed millisecond radio bursts by Thornton et al. in a survey with the Parkes radio telescope at 1.4 GHz point towards an emerging population of sources at cosmological distances whose origin is currently unclear. Here we demonstrate that the scattering effects at lower radio frequencies are less than previously thought, and that the bursts could be detectable at redshifts out to about $z=0.5$ in surveys below 1 GHz. Using a source model in which the bursts are standard candles with bolometric luminosities $\sim 8 \times 10^{44}$ ergs/s uniformly distributed per unit comoving volume, we derive an expression for the observed peak flux density as a function of redshift and use this, together with the rate estimates found by Thornton et al. to find an empirical relationship between event rate and redshift probed by a given survey. The non-detection of any such events in Arecibo 1.4 GHz survey data by Deneva et al., and the Allen Telescope Array survey by Simeon et al. is consistent with our model. Ongoing surveys in the 1--2 GHz band should result in further discoveries. At lower frequencies, assuming a typical radio spectral index $α=-1.4$, the predicted peak flux densities are 10s of Jy. As a result, surveys of such a population with current facilities would not necessarily be sensitivity limited and could be carried out with small arrays to maximize the sky coverage. We predict that sources may already be present in 350-MHz surveys with the Green Bank Telescope. Surveys at 150 MHz with 30 deg$^2$ fields of view could detect one source per hour above 30 Jy.
