description: Superconducting circuits are exceptionally flexible, enabling many different devices from sensors to quantum computers. Separately, epitaxial semiconductor devices such as spin qubits in silicon offer more limited device variation but extraordinary quantum properties for a solid-state system. It might be possible to merge the two approaches, making single-crystal superconducting devices out of a semiconductor by utilizing the latest atomistic fabrication techniques. Here we propose superconducting devices made from precision hole-doped regions within a silicon (or germanium) single crystal. We analyze the properties of this superconducting semiconductor and show that practical superconducting wires, Josephson tunnel junctions or weak links, superconducting quantum interference devices (SQUIDs), and qubits are feasible. This work motivates the pursuit of "bottom-up" superconductivity for improved or fundamentally different technology and physics.

Supplementary materials from Functional constraints channel mandible shape ontogenies in rodents

description: In mammals, postnatal growth plays an essential role in the acquisition of the adult shape. During this period, the mandible undergoes many changing functional constraints, leading to spatialization of bone formation and remodelling to accommodate various dietary and behavioural changes. The interactions between the bone, muscles and teeth drive this developmental plasticity, which, in turn, could lead to convergences in the developmental processes constraining the directionality of ontogenies, their evolution and thus the adult shape variation. To test the importance of the interactions between tissues in shaping the ontogenetic trajectories, we compared the mandible shape at five postnatal stages on three rodents: the house mouse, the Mongolian gerbil and the golden hamster, using geometric morphometrics. After an early shape differentiation, by both longer gestation and allometric scaling in gerbils or early divergence of postnatal ontogeny in hamsters in comparison with the mouse, the ontogenetic trajectories appear more similar around weaning. The changes in muscle load associated with new food processing and new behaviours at weaning seem to impose similar physical constraints on the mandible, driving the convergences of the ontogeny at that stage despite an early anatomical differentiation. Nonetheless, mice present a rather different timing compared with gerbils or hamsters.

description: This paper proposes a novel lexicon-based unsupervised sentimental analysis method to measure the $``\textit{hope}"$ and $``\textit{fear}"$ for the 2022 Ukrainian-Russian Conflict. $\textit{Reddit.com}$ is utilised as the main source of human reactions to daily events during nearly the first three months of the conflict. The top 50 $``hot"$ posts of six different subreddits about Ukraine and news (Ukraine, worldnews, Ukraina, UkrainianConflict, UkraineWarVideoReport, UkraineWarReports) and their relative comments are scraped and a data set is created. On this corpus, multiple analyses such as (1) public interest, (2) hope/fear score, (3) stock price interaction are employed. We promote using a dictionary approach, which scores the hopefulness of every submitted user post. The Latent Dirichlet Allocation (LDA) algorithm of topic modelling is also utilised to understand the main issues raised by users and what are the key talking points. Experimental analysis shows that the hope strongly decreases after the symbolic and strategic losses of Azovstal (Mariupol) and Severodonetsk. Spikes in hope/fear, both positives and negatives, are present after important battles, but also some non-military events, such as Eurovision and football games.

description: Associated to the two types of finite dimensional simple superalgebras, there are the general linear Lie superalgebra and the queer Lie superalgebra. The universal enveloping algebras of these Lie superalgebras act on the tensor spaces of the natural representations and, thus, define certain finite dimensional quotients, the Schur superalgebras and the queer Schur superalgebra. In this paper, we introduce the quantum analogue of the queer Schur superalgebra and investigate the presentation problem for both the queer Schur superalgebra and its quantum analogue.

Our main results show that intermediate co-t-structures are in bijection with two-term silting subcategories, and also with support tau-tilting subcategories under some assumptions. We also show that support tau-tilting subcategories are in bijection with certain finitely generated torsion classes. These generalise results by Adachi, Iyama, and Reiten.

description: We explore various aspects of supersymmetric black hole partition functions in four-dimensional toroidally compactified heterotic string theory. These functions suffer from divergences owing to the hyperbolic nature of the charge lattice in this theory, which prevents them from having well-defined modular transformation properties. In order to rectify this, we regularize these functions by converting the divergent series into indefinite theta functions, thereby obtaining fully regulated single-centered black hole partitions functions.

Predictive and Dynamic Mechanisms of Rhythm and Groove

description: This dissertation investigates the predictive and dynamic mechanisms underlying rhythm processing and groove. It accomplishes this by measuring the pleasurable urge to move to music (groove) and the beat perception abilities necessary for producing it. The first two studies do this by manipulating rhythmic complexity while recording changes in pupil size to assess cognitive effort, which is theorized to be necessary for reducing prediction error surrounding the beat. The second study additionally recorded the variability and intensity of participants’ foot taps as a measure of how precisely and confidently they could synchronize to the musical beat,
 respectively, to examine their relationship to groove. The third study explored how beat perception ability (which impacted the results of the first two studies) is shaped by experience and expertise. Namely, it examined whether inactive musicians retain the heightened beat perception abilities of their regularly practicing counterparts. In this work, I demonstrate that: 1) the pupil drift rate indexes groove ratings, 2) pickups elicit greater pupil dilations while 3) syncopations elicit greater groove ratings, 4) synchronizing to the beat increases groove ratings and pupil dilations, 5) tapping becomes softer and less precise with increasing complexity, 6) the inverted U-shaped curve between rhythmic complexity and groove is stronger for real music than synthetic drumbeats, and 7) greater beat perception is associated with more musical training,
 more precise tapping, and more prominent inverted U-shaped curves. In summary, this
 dissertation contributes a number of novel findings, extensions, and replications to the rich
 literature on beat perception and groove.
Primordial black holes from Volkov-Akulov-Starobinsky supergravity

description: We study the formation of primordial black holes (PBH) in the Starobinsky supergravity coupled to the nilpotent superfield describing Volkov-Akulov goldstino. By using the no-scale Kähler potential and a polynomial superpotential, we find that under certain conditions our model can describe effectively single-field inflation with the ultra-slow-roll phase that appears near a critical (nearly-inflection) point of the scalar potential. This can lead to the formation of PBH as part of (or whole) dark matter, while keeping the inflationary spectral tilt and the tensor-to-scalar ratio in good agreement with the current cosmic microwave background (CMB) bounds. After inflation, supersymmetry is spontaneously broken at the inflationary scale with the vanishing cosmological constant.

description: We study N=2 supersymmetric gauge theories on the product of a two-sphere and a cylinder. We show that the low-energy dynamics of a BPS sector of such a theory is described by a quantum integrable system, with the Planck constant set by the inverse of the radius of the sphere. If the sphere is replaced with a hemisphere, then our system reduces to an integrable system of the type studied by Nekrasov and Shatashvili. In this case we establish a correspondence between the effective prepotential of the gauge theory and the Yang-Yang function of the integrable system.

Instruments that assess identity, motivation, and self-efficacy of clinical educators: a scoping review

description: The critical importance of the clinical educator (CE) role in physiotherapy is well established. Several operational barriers to physiotherapists participating in CE roles have also been identified. However, limited attention has been paid to the underlying psychological constructs which may also influence physiotherapists participating in CE roles. Within the more established field of medicine the constructs of identity as an educator, motivation, and self-efficacy as an educator have been demonstrated to impact the performance and perseverance of clinicians in educator roles. We propose that these constructs may similarly impact physiotherapists. This scoping review aims to identify an instrument currently available within the healthcare educator literature that assess the constructs of identity, motivation, and self-efficacy of clinician’s participating in clinical education. This instrument would need to be suitable to conduct a cross-sectional assessment of the Australian physiotherapy workforce. The scoping review will comprise a search of databases (including PubMed, Embase, CINAHL, and Scopus) where references will be screened in accordance with the Joanna Briggs Institute guidelines. The outcome of this review will be a compilation of the instruments currently available that assess identity, motivation, and self-efficacy of healthcare educators.

description: The wave-particle duality of light has led to two different encodings for optical quantum information processing. Several approaches have emerged based either on particle-like discrete-variable states, e.g. finite-dimensional quantum systems, or on wave-like continuous-variable states, e.g. infinite-dimensional systems. Here, we demonstrate the first measurement-induced generation of entanglement between optical qubits of these different types, located at distant places and connected by a lossy channel. Such hybrid entanglement, which is a key resource for a variety of recently proposed schemes, including quantum cryptography and computing, enables to convert information from one Hilbert space to the other via teleportation and therefore connect remote quantum processors based upon different encodings. Beyond its fundamental significance for the exploration of entanglement and its possible instantiations, our optical circuit opens the promises for heterogeneous network implementations, where discrete and continuous-variable operations and techniques can be efficiently combined.
Nonlinear group survival in Kimura's model for the evolution of altruism

Year: 2013
Subjects: subject: Populations and Evolution (q-bio.PE)

description: Establishing the conditions that guarantee the spreading or the sustenance of altruistic traits in a population is the main goal of intergroup selection models. Of particular interest is the balance of the parameters associated to group size, migration and group survival against the selective advantage of the non-altruistic individuals. Here we use Kimura's diffusion model of intergroup selection to determine those conditions in the case the group survival probability is a nonlinear non-decreasing function of the proportion of altruists in a group. In the case this function is linear, there are two possible steady states which correspond to the non-altruistic and the altruistic phases. At the discontinuous transition line separating these phases there is a non-ergodic coexistence phase. For a continuous concave survival function, we find an ergodic coexistence phase that occupies a finite region of the parameter space in between the altruistic and the non-altruistic phases, and is separated from these phases by continuous transition lines. For a convex survival function, the coexistence phase disappears altogether but a bistable phase appears for which the choice of the initial condition determines whether the evolutionary dynamics leads to the altruistic or the non-altruistic steady state.

description: We measure the cross-correlation of cosmic microwave background lensing convergence maps derived from Atacama Cosmology Telescope data with galaxy lensing convergence maps as measured by the Canada-France-Hawaii Telescope Stripe 82 Survey. The CMB-galaxy lensing cross power spectrum is measured for the first time with a significance of 4.2σ, which corresponds to a 12% constraint on the amplitude of density fluctuations at redshifts ~ 0.9. With upcoming improved lensing data, this novel type of measurement will become a powerful cosmological probe, providing a precise measurement of the mass distribution at intermediate redshifts and serving as a calibrator for systematic biases in weak lensing measurements.

description: We investigate self-similar scalar field solutions to the Einstein equations in whole cylinder symmetry. Imposing self-similarity on the spacetime gives rise to a set of single variable functions describing the metric. Furthermore, it is shown that the scalar field is dependent on a single unknown function of the same variable and that the scalar field potential has exponential form. The Einstein equations then take the form of a set of ODEs. Self-similarity also gives rise to a singularity at the scaling origin. We extend the work of [1], which determined the global structure of all solutions in the causal past of the singularity. We identified a class of solutions that evolves through the past null cone of the singularity. We give the global structure of these solutions and show that the singularity is censored in all cases.

Ein wesentliches Arbeitsinstrument in diesem Prozeß stellt die Zentrale Archäologische Datenbank (kurz ZADAB) dar. Hier werden in verschiedenen Datenbankmodulen die archäologischen Informationen des Amtes verwaltet. Dazu gehören diverse archäologische Aktivitäten wie Zufallsmeldungen, Prospektionen, Ausgrabungen , Luftbilder, aber auch Bodendenkmäler und archäologische Plätze. Alle projektrelevanten Daten, von den Fundstellen über die Kulturlandschaftsrelikte, den Luftbildern bis zu den Störzonen werden in einem geographischen Informationssystem zusammengeführt und können so leicht in Beziehung gesetzt und ausgewertet werden.
description: A working group belonging to the field Walking unit of the Rhineland Archaeological State Service (RAB) is preparing a contribution to the land use plan of the city of Erkelenz, Heinsberg district, as part of an EC project on planning and archaeology (PLANARCH 2). As a result, Information on all known archaeological Sites will be provided to the city Council. A strategy for the integration and management of archaeological Sites and historic landscape features within the planning process will be developed. One key element is the digital Sites and monuments record (Zentrale Archäologische Datenbank). This database consists of different units which störe the institution's archaeological knowledge including all kinds of archaeological activities such as Chance finds, survey results, excavations, aerial photos, listed monuments , and archaeological sites.
The Information concerning sites, historic landscape features, aerial photos, and zones of destruction are linked with spatial data within a GIS for easy assessment and analysis.

description: Anhand von archäozoologischen Daten aus der Literatur, von Keramikfunden, Schrift- und Sprachhinweisen, genetischen Untersuchungen sowie wirtschaftlichen und klimatischen Überlegungen wurde in dieser Magisterarbeit die Theorie der „Secondary Products Revolution“ überprüft. Der thematische Schwerpunkt lag dabei auf dem historischen Beginn der Milchnutzung und der Laktosetoleranz. Es konnte gezeigt werden, dass die Nutzung der Milch zwar wahrscheinlich schon kurz nach der Domestikation der Schafe und Ziegen im Vorderen Orient begonnen, doch bis zur heutigen Zeit nur eine untergeordnete Rolle in der Ernährung der Menschen gespielt hat. Eine intensive Milchnutzung setzte jedoch mit der Haltung großer Rinderherden wie in den mitteleuropäischen Breiten zur Zeit der Bandkeramik ein. Die Verwendung der Rinder als Arbeitstiere stellte nach den archäozoologischen Daten schon sehr früh eine wichtige Nutzungsform dar. Die Wollschafe erfuhren jedoch erst mit Beginn der Bronzezeit in Zentraleuropa eine gesteigerte Bedeutung. Der abschließende Vergleich bestätigte, dass die Nutzungsform stark von den jeweiligen klimatischen, landschaftlichen und historischen Gegebenheiten abhängt.

The emphasis lay on the beginning of dairying and on adult lactose tolerance. It could be shown that although dairying was probably practiced as soon as animals were domesticated, milk was transformed
into storable products such as hard cheese. The use of fresh milk that lead to adult lactose tolerance probably began with the herding of milk cattle in Bandkeramik Central Europe. Furthermore, the assessment of the osteological evidence showed that cattle were used for purposes other than for meat (especially traction) since neolithic times whereas the importance of wool sheep increased in Bronze Age Central Europe. The fi nal discussion set the use of cattle within a worldwide comparative perspective and showed its dependence on climate and geography.

description: Die Paläoanthropologie zählt unter den öffentlichkeitsorientierten biologischen Wissenschaften zu den faszinierendsten Disziplinen, hat aber auch gleichzeitig den diskreditierenden Vorwurf zu gegenwärtigen, keine sehr glaubwürdige Disziplin zu sein. Zielsetzung dieses Beitrags ist es, dieses Vorurteil als einseitige Außensicht zu entkräften und die paläoanthropologische Forschung als eine innovative Wissenschaft zu kennzeichnen, deren Aufgabe es ist, den Prozess der Menschwerdung als adaptive Entwicklung in der Primaten-Evolution zu verstehen. Neben den Prinzipien werden die wichtigsten Methoden, mit denen es gelingt, die in Homininenfossilien verschlüsselten Informationen akribisch zu dekodieren, exemplarisch aufgezeigt. ’Begründete’ Paläoanthropologie, um die es hier geht,
ist stets theoriegeleitete und hochgradig inter- und multidisziplinär vernetzte Stammesgeschichtsforschung. Nur mit einem komplexen vergleichend- primatologischen Ansatz kann es gelingen, den Prozess und die Etappen der Menschwerdung zu rekonstruieren und langfristig gültige Hominisationsmodelle und phylogenetische Stammbäume zu erstellen. Mehr als Modelle (Jeweilsbilder sensu Heberer 1972), die aufgrund neuer Methoden und Fakten ständig überprüft werden müssen, werden es jedoch niemals sein. Wir modellieren nur!
description: Palaeoanthropology is as a publicity-oriented biological science one of the most fascinating disciplines which has to deal simultaneously with the discrediting allegation of a low credibility of her results. This paper aims to invalidate this prejudice as a singleedged exterior view and to characterise palaeoanthropological research as an innovative science which aims to explain the process of hominisation as evolutionary adaptations within the order Primates. The principles and methods of theory-guided studies of fossil remains
are exemplarily explained. Palaeoanthropological approaches meticulously try to decode the information hidden in hominid fossils, to reconstruct the process and the phylogenetical steps of hominisation and to conceptualize a substantiated – but always hypothetical – pedigree of our origin. We are just modelling.

description: We obtain exhaustive results and treat in a unified way the question of boundedness, compactness, and weak compactness of composition operators from the Bloch space into any space from a large family of conformally invariant spaces that includes the classical spaces like $BMOA$, $Q_α$, and analytic Besov spaces $B^p$. In particular, by combining techniques from both complex and functional analysis, we prove that in this setting weak compactness is equivalent to compactness. For the operators into the corresponding "small" spaces we also characterize the boundedness and show that it is equivalent to compactness.

On factors of Gibbs measures for almost additive potentials

description: Let $(X, σ_X), (Y, σ_Y)$ be one-sided subshifts with the specification property and $π:X\rightarrow Y$ a factor map. Let $μ$ be a unique invariant Gibbs measure for a sequence of continuous functions $\F=\{\log f_n\}_{n=1}^{\infty}$ on $X$, which is an almost additive potential with bounded variation. We show that $πμ$ is also a unique invariant Gibbs measure for a sequence of continuous functions $\G=\{\log g_n\}_{n=1}^{\infty}$ on $Y$. When $(X, σ_X)$ is a full shift, we characterize $\G$ and $μ$ by using relative pressure. This almost additive potential $\G$ is a generalization of a continuous function found by Pollicott and Kempton in their work on the images of Gibbs measures for continuous functions under factor maps. We also consider the following question: Given a unique invariant Gibbs measure $ν$ for a sequence of continuous functions $\F_2$ on $Y$, can we find an invariant Gibbs measure $μ$ for a sequence of continuous functions $\F_1$ on $X$ such that $πμ=ν$? We show that such a measure exists under a certain condition. If $(X, σ_X)$ is a full shift and $ν$ is a unique invariant Gibbs measure for a function in the Bowen class, then we can find a preimage $μ$ of $ν$ which is a unique invariant Gibbs measure for a function in the Bowen class.

description: Recent observations by the Fermi Large Area Telescope (LAT) and the High Energy Stereoscopic System (H.E.S.S.) have revealed globular clusters (GC) to be sources of high-energy (HE) and very-high-energy (VHE) gamma-rays. It has been suggested that the presence of large numbers of millisecond pulsars (MSPs) within these clusters may be either directly responsible for these gamma-ray fluxes through emission of pulsed curvature radiation, or indirectly through the injection of relativistic leptons into the cluster. These relativistic particles are plausibly re-accelerated in shocks, created by the collision of stellar winds, before interacting with the soft-photon radiation field set up by the stellar population of the host cluster. Inverse Compton (IC) scattering then produces gamma-radiation in the TeV band. In order to calculate the IC spectrum, an accurate profile for the energy density of the soft-photon field is required. We construct such a profile by deriving a radially-dependent expression for the stellar energy density, and then solve it numerically. As a next step, the average energy density values for three different regions of the cluster (demarcated by its core, half-mass, and tidal radii) are determined, which we consequently import into an existing radiation code to predict the TeV gamma-ray spectrum. As an application, we consider the case of Terzan 5, boasting a population of 34 radio MSPs, and compare our predicted spectrum with that measured by H.E.S.S.

We derive redshifts, metallicities and star formation rates (SFRs) from the [OII], [OIII] and Hbeta nebular emission lines and exploit the multi-wavelength photometry available in CANDELS to measure stellar masses. We find the mass-metallicity relation (MZR) derived from our data to have the same trend as previous determinations in the range 0

description: Recent experiments in cell biology have probed the impact of artificially-induced intracellular flows in the spatiotemporal organisation of cells and organisms. In these experiments, mild dynamical heating via focused infrared light from a laser leads to long-range, thermoviscous flows of the cytoplasm inside a cell, a method popularised in cell biology as FLUCS (focused-light-induced cytoplasmic streaming). Here, we present a fully analytical, theoretical model describing the fluid flow and transport of tracers induced by the laser at all length scales in two-dimensional confinement. The focused light causes a small, local temperature change, which in turn results in a small change in the density and viscosity of the fluid locally. We analytically solve for the instantaneous flow field due to the translation of a heat spot of arbitrary time-dependent amplitude along a scan path. We show that the leading-order instantaneous flow results purely from thermal expansion. It is proportional to the magnitude of the temperature perturbation, with far-field behaviour typically dominated by a source or sink flow and proportional to the rate of change of the heat-spot amplitude. In contrast, and in agreement with experimental measurements, the net displacement of a tracer due to a full scan of the heat spot is quadratic in the heat-spot amplitude, as it results from the interplay of thermal expansion and thermal viscosity changes. The corresponding average velocity of tracers over a scan is a hydrodynamic source dipole in the far field, with direction dependent on the relative importance of thermal expansion and thermal viscosity changes. Our quantitative findings show excellent agreement with recent experimental results and will enable the design of new controlled experiments to establish the physiological role of physical transport processes inside cells.

description: \ersn\, is considered, together with \erti, as a realization of the XY antiferromagnet on the pyrochlore lattice. We present magnetization measurements confirming that \ersn\, does not order down to 100 mK but exhibits a freezing below 200 mK. Our neutron scattering experiments evidence the strong XY character of the \er moment and point out the existence of short range correlations in which the magnetic moments are in peculiar configurations, the Palmer-Chalker states, predicted theoretically for an XY pyrochlore antiferromagnet with dipolar interactions. Our estimation of the \ersn\, parameters confirm the role of the latter interactions on top of relatively weak and isotropic exchange couplings.

description: Several gamma-ray bursts (GRBs) last much longer (~hours) in gamma-rays than typical long GRBs (~ minutes), and recently it was proposed that these "ultra-long GRBs" may form a distinct population, probably with a different (e.g. blue supergiant) progenitor than typical GRBs. However, Swift observations suggest that many GRBs have extended central engine activities manifested as flares and internal plateaus in X-rays. We perform a comprehensive study on a large sample of Swift GRBs with XRT observations to investigate GRB central engine activity duration and to determine whether ultra-long GRBs are unusual events. We define burst duration t_burst based on both gamma-ray and X-ray light curves rather than using gamma-ray observations alone. We find that t_burst can be reliably measured in 343 GRBs. Within this "good" sample, 21.9% GRBs have t_burst >=10^3 s and 11.5% GRBs have t_burst >=10^4 s. There is an apparent bimodal distribution of t_burst in this sample. However, when we consider an "undetermined" sample (304 GRBs) with t_burst possibly falling in the gap between GRB duration T_90 and the first X-ray observational time, as well as a selection effect against t_burst falling into the first Swift orbital "dead zone" due to observation constraints, the intrinsic underlying t_burst distribution is consistent with being a single component distribution. We found that the existing evidence for a separate ultra-long GRB population is inconclusive, and further multi-wavelength observations are needed to draw a firmer conclusion. We also discuss the theoretical implications of our results. In particular, the central engine activity duration of GRBs is generally much longer than the gamma-ray T90 duration and it does not even correlate with T90. It would be premature to make a direct connection between T90 and the size of the progenitor star.
