description: Bateman's principles posit that male fitness varies more, and relies more on mate acquisition, than female fitness. While Bateman's principles should apply to any organism producing gametes of variable sizes, their application to plants is potentially complicated by the high levels of polyandry suspected for plants, and by variation in the spatial distribution of prospective mates. Here we quantify the intensity of sexual selection by classical Bateman metrics using two common gardens of the wind-pollinated dioecious, Mercurialis annua. Consistent with Bateman's principles, males displayed significantly positive Bateman gradients (a regression of fitness on mate number), whereas the reproductive success of females was independent of their ability to access mates. A large part of male fitness was explained by their mate number, which in turn was associated with males' abilities to disperse pollen. Our results suggest that sexual selection can act in plant species in much the same way as in many animals, increasing the number of mates through traits that promote pollen dispersal.

description: The paper focuses on the effect of the scanning strategies on the microstructural evolution, defect formation, and macro-hardness performance of laser-powder bed fusion (L-PBF) produced samples of low alloy 20MnCr5 steel. Respect to the scanning strategies, advanced characterization techniques were employed to study (i) as-built microstructure, (ii) inclusion size and distribution, and (iii) details of compositional variation around porosity and within the build. Microstructural characterization shows that the chessboard scanning strategy can provide a favorable microstructure for the improvement of mechanical performance. However, macro-hardness results show a lower mechanical performance compared to the linear scanning strategy samples, which is contradicted by the improved microstructure. Experimental results reveal that the chessboard scanning strategy promotes the oxidation reaction and in-situ oxide (SiO2) formation in L-PBF, which leads to significant defect formation due to the excessive thermal profile from the overlap of the laser. This has been validated through finite element analysis and thermodynamic computation. The advantages of microstructural improvement using the chessboard strategy can only be realized with strict control of the metallurgical quality during the L-PBF process. Thermal profile optimization and oxygen elimination during the L-PBF process could be critical for the improved metallurgical quality and superior mechanical performance of the as-built components.
A Family of Current References Based on 2T Voltage References: Demonstration in 0.18-$μ$m with 0.1-nA PTAT and 1.1-$μ$A CWT 38-ppm/$^\circ$C Designs

description: The robustness of current and voltage references to process, voltage and temperature (PVT) variations is paramount to the operation of integrated circuits in real-world conditions. However, while recent voltage references can meet most of these requirements with a handful of transistors, current references remain rather complex, requiring significant design time and silicon area. In this paper, we present a family of simple current references consisting of a two-transistor (2T) ultra-low-power voltage reference, buffered onto a voltage-to-current converter by a single transistor. Two topologies are fabricated in a 0.18-$μ$m partially-depleted silicon-on-insulator (SOI) technology and measured over 10 dies. First, a 7T nA-range proportional-to-absolute-temperature (PTAT) reference intended for constant-$g_m$ biasing of subthreshold operational amplifiers demonstrates a 0.096-nA current with a line sensitivity (LS) of 1.48 %/V, a temperature coefficient (TC) of 0.75 %/$^\circ$C, and a variability $(σ/μ)$ of 1.66 %. Then, two 4T+1R $μ$A-range constant-with-temperature (CWT) references with (resp. without) TC calibration exhibit a 1.09-$μ$A (resp. 0.99-$μ$A) current with a 0.21-%/V (resp. 0.20-%/V) LS, a 38-ppm/$^\circ$C (resp. 290-ppm/$^\circ$C) TC, and a 0.87-% (resp. 0.65-%) $(σ/μ)$. In addition, portability to common scaled CMOS technologies, such as 65-nm bulk and 28-nm fully-depleted SOI, is discussed and validated through post-layout simulations.

A New Fragment from the Letters of Aristotle
Creators: name: Panegyres, Konstantine
Publisher: name: Fondazione Università Ca’ Foscari Venezia, Italia
Year: 2020

description:

An Arabic manuscript preserves what purports to be a letter from Aristotle to a noblewoman. Closer scrutiny of its contents suggests that the letter was addressed to Olympias (mother of Alexander the Great) on the death of her brother (Alexander I of Epirus). This identification is important because Aristotle was said to have left behind at his death one book of letters to Olympias, an edition of which was published in antiquity. The question is therefore raised as to whether the fragment is genuine or spurious.

description: We investigate the self-correcting properties of a network of Majorana wires, in the form of a trijunction, in contact with a parity-preserving thermal environment. As opposed to the case where Majorana bound states (MBSs) are immobile, braiding MBSs within a trijunction introduces dangerous error processes that we identify. Such errors prevent the lifetime of the memory from increasing with the size of the system. We confirm our predictions with Monte Carlo simulations. Our findings put a restriction on the degree of self-correction of this specific quantum computing architecture.

Tra militia e amor: il nesso castra sequi nella poesia erotico-elegiaca

description:

The paper contextualises the occurrences of the iunctura castra sequi in three elegiac Latin poems (Prop. 2.10.19, Tib. 2.6.1 and Ov. am. 3.8.26), with the addition of two further passages (Verg. ecl. 10.23 and Lucan. 2.348): these latter ones, indeed, though belonging to different eidetic contexts, exhibit important links to characteristically elegiac topoi. In all of the passages under consideration, castra sequi reveals itself, so to say, as a marker of the crucial dichotomy between love and war, militia and amor, which can only find some sort of recomposition via the metaphorical plexus of militia amoris.

The Heritability of Foreign Policy Preferences

description: Attitudes towards foreign policy have typically been explained by ideological and demographic factors. We approach this study from a different perspective and ex amine the extent to which foreign policy preferences correspond to genetic variation. Using data from the Minnesota Twin Family Study, we show that a moderate share of individual differences in the degree to which one's foreign policy preferences are hawkish or dovish can be attributed to genetic variation. We also show, based on a bivariate twin model, that foreign policy preferences share a common genetic source of variation with political ideology. This result presents the possibility that ideology may be the causal pathway through which genes affect foreign policy preferences.

Furthermore, we prove that the regularity of the domain $\Om_0$ is preserved by time evolution.

description: We present a method to detect bipartite entanglement based on number-phase-like uncertainty relations in split spin ensembles. First, we derive an uncertainty relation that plays the role of a number-phase uncertainty for spin systems. It is important that the relation is given with well-defined and easily measurable quantities, and that it does not need assuming infinite dimensional systems. Based on this uncertainty relation, we show how to detect bipartite entanglement in an unpolarized Dicke state of many spin-1/2 particles. The particles are split into two subensembles, then collective angular momentum measurements are carried out locally on the two parts. First, we present a bipartite Einstein-Podolsky-Rosen (EPR) steering criterion. Then, we present an entanglement condition that can detect bipartite entanglement in such systems. We demonstrate the utility of the criteria by applying them to a recent experiment given in K. Lange et al. [Science 360, 416 (2018)] realizing a Dicke state in a Bose-Einstein condensate of cold atoms, in which the two subensembles were spatially separated from each other. Our methods also work well if split spin-squeezed states are considered. We show in a comprehensive way how to handle experimental imperfections, such as the nonzero particle number variance including the partition noise, and the fact that, while ideally BECs occupy a single spatial mode, in practice the population of other spatial modes cannot be fully suppressed.

description: It is shown that the so-called "Yukawaon" model can give a unified description of masses, mixing and $CP$ violation parameters of quarks and leptons without using any hierarchical (family number-dependent) parameters besides the charged lepton masses. Here, we have introduced a phase matrix $P={\rm daig}(e^{i ϕ_1}, e^{i ϕ_2}, e^{i ϕ_3})$ with the phase parameters $(ϕ_1, ϕ_2, ϕ_3)$ which are described in terms of family number-independent parameters, together with using only the charged lepton mass parameters as the family number-dependent parameters. In this paper, the $CP$ violating phase parameters $δ_{CP}^q$ and $δ_{CP}^\ell$ in the standard expression of $V_{CKM}$ and $U_{PMNS}$ are predicted as $δ_{CP}^q \simeq 72^\circ$ and $δ_{CP}^\ell \simeq -76^\circ$, respectively, i.e. $δ_{CP}^\ell \sim - δ_{CP}^q$.

description: In order to investigate the relationship between the so-called stripe correlations and the high-Tc superconductivity, we have carried out magnetic susceptibility and zero-field muon-spin-relaxation measurements in partially Fe-substituted La2-xSrxCu1-yFeyO4 (LSCFO). It has been found that the Fe substitution induces successive magnetic transitions in the overdoped regime, namely, a spin-glass transition of Fe3+ spins due to the RKKY interaction based on itinerant spins at higher temperatures and a stripe-order transition of localized Cu2+ spins at lower temperatures. The stripe-order transition disappears at the hole concentration of ~0.28 per Cu which coincides with the endpoint of the superconductivity in pristine La2-xSrxCuO4, suggesting that the stripe correlations are closely related to the high-Tc superconductivity in the overdoped regime as well as in the underdoped regime. As for the spin-glass state, it has been found that the contribution of polarized itinerant spins to the muon-spin depolarization is not negligible. Taking into account neutron-scattering results by R.-H. He et al. [Phys. Rev. Lett. 107, 127002 (2011)] that a spin-density-wave (SDW) order has been observed in overdoped LSCFO, the present results demonstrate the presence of a novel coexistent state of a SDW order and a spin-glass state.

description: A promising technique under development for epithelial pre-cancer and early cancer detection is Reflectance and Fluorescence Spectroscopy. The integration of spectroscopic devices into existing optical examinations has the potential to substantially improve clinical practice. Fiber optic cables provide a flexible solution for an adequate optical interface between the spectroscopic device and the sample to be interrogated in situ. Various fiber-optic probe designs have been used. Despite such a widespread use of fiber-optic probes in diverse applications, only limited work has been conducted towards deeper understanding of the effects of probe design on tissue spectroscopic studies. With this objective in mind I plan to investigate a multi fiber probe design with angled collection geometry to estimate maximum penetration depth at which typical biological structures can be detected

description: Recent work has shown that collective single photon emission from an ensemble of resonate two-level atoms, i.e. single photon superradiance, is a rich field of study. The present paper addresses the flip side of superradiance, i.e. subradiance. Single photon subradiant states are potentially stable against collective spontaneous emission and can have ultrafast readout. In particular it is shown how many atom collective effects provide a new way to control spontaneous emission by preparing and switching between subradiant and superradiant states.

description: Monozygotic (MZ) twins are genetically identical at conception, making them informative subjects for studies on somatic mutations. Copy number variants (CNVs) are responsible for a substantial part of genetic variation, have relatively high mutation rates, and are likely to be involved in phenotypic variation. We conducted a genome-wide survey for post-twinning de novo CNVs in 1,097 MZ twin pairs. Comparisons between MZ twins were made by CNVs measured in DNA from blood or buccal epithelium with the Affymetrix 6.0 microarray and two calling algorithms. In addition, CNV concordance rates were compared between the different sources of DNA, and gene-enrichment association analyses were conducted for thought problems (TP) and attention problems (AP) using CNVs concordant within MZ pairs. We found a total of 153 putative post-twinning de novo CNVs >100 kb, of which the majority resided in 15q11.2. Based on the discordance of raw intensity signals a selection was made of 20 de novo CNVs for a qPCR validation experiments. Two out of 20 post-twinning de novo CNVs were validated with qPCR in the same twin pair. The 13-year-old MZ twin pair that showed two discordances in CN in 15q11.2 in their buccal DNA did not show large phenotypic differences. From the remaining 18 putative de novo CNVs, 17 were deletions or duplications that were concordant within MZ twin pairs. Concordance rates within twin pairs of CNV calls with CN ≠ 2 were ~80%. Buccal epithelium-derived DNA showed a slightly but significantly higher concordance rate, and blood-derived DNA showed significantly more concordant CNVs per twin pair. The gene-enrichment analyses on concordant CNVs showed no significant associations between CNVs overlapping with genes involved in neuronal processes and TP or AP after accounting for the source of DNA.

description:

A good example of literature’s power to continuously rewrite geographic space by renewing inherited paradigms could be found in Prudentius’ Peristephanon, which provides a sort of re-mapping of the Western landscape in a martyrial perspective. My paper focuses in particular on the narration of Cassian’s martyrdom, providing a new in-depth analysis of Peristephanon IX. Firstly, the poet claims possession of the martyr’s place, Forum Cornelii, by dismissing its pagan past; then, in the ekphrasis of the fresco depicting the martyr, he enacts a complex itinerary of the gaze and elaborates a complex retractatio of the description of Juno’s temple of Verg. Aen. 1.446-465; finally, the introduction of a second-degree narrator provides an authoritative interpretation of the image, leading to appropriate devotion to the saint. The poem, thus, provides both an interesting example of integrated intermediality, and a reflection on the hermeneutical risks of unmediated viewing in a Christian scopic regime.

description: Decarbonization in the energy sector has been accompanied by an increased penetration of new renewable energy sources in electric power systems. Such sources differ from traditional productions in that, first, they induce larger, undispatchable fluctuations in power generation and second, they lack inertia. Therefore, substituting new renewables for traditional generation induces stronger and more frequent disturbances and modifies the way disturbances propagate across AC electric power grids. Recent measurements have indeed reported long, non-Gaussian tails in the distribution of local grid-frequency data. Large frequency deviations may induce grid instabilities, leading in worst-case scenarios to cascading failures and large-scale blackouts. In this manuscript, we investigate how correlated noise disturbances, characterized by the cumulants of their distribution, propagate through meshed, high-voltage power grids. We show that for a single source of fluctuations, non-Gaussianities in the form of finite skewness and positive kurtosis of the noise distribution propagate over the entire network when the noise correlation time is larger than the network's intrinsic time scales, but that they vanish over short distances if the noise fluctuates rapidly. We furthermore show that a Berry-Esseen theorem leads to the vanishing of non-Gaussianities as the number of uncorrelated noise sources increases. Our results show that the persistence of non-Gaussian fluctuations of feed-in power have a global impact on power-grid dynamics when they fluctuate over time scales larger than the intrinsic time scales of the system, which, we argue, is the relevant regime in real power grids. Our predictions are corroborated by numerical simulations on realistic models of power grids.

description: The presence of light scalars can have profound effects on early universe cosmology, influencing its thermal history as well as paradigms like inflation and baryogenesis. Effective supergravity provides a framework to make quantifiable, model-independent studies of these effects. The Riemanian curvature of the Kahler manifold spanned by scalars belonging to chiral superfields, evaluated along supersymmetry breaking directions, provides an order parameter (in the sense that it must necessarily take certain values) for phenomena as diverse as slow roll modular inflation, non-thermal cosmological histories, and the viability of Affleck-Dine baryogenesis. Within certain classes of UV completions, the order parameter for theories with $n$ scalar moduli is conjectured to be related to invariants of $n$-ary cubic forms (for example, for models with three moduli, the order parameter is given by the ring of invariants spanned by the Aronhold invariants). Within these completions, and under the caveats spelled out, this may provide an avenue to obtain necessary conditions for the above phenomena that are in principle calculable given nothing but the intersection numbers of a Calabi-Yau compactification geometry. As an additional result, abstract relations between holomorphic sectional and bisectional curvatures are utilized to constrain Affleck-Dine baryogenesis on a wide class of Kahler geometries.

description: A new kind of spline geometric method approach is presented. Its main ingredient is the use of well established spline spaces forming a discrete de Rham complex to construct a primal sequence $\{X^k_h\}^n_{k=0}$, starting from splines of degree $p$, and a dual sequence $\{\tilde{X}^k_h\}_{k=0}^n$, starting from splines of degree $p-1$. By imposing homogeneous boundary conditions to the spaces of the primal sequence, the two sequences can be isomorphically mapped into one another. Within this setup, many familiar second order partial differential equations can be finally accommodated by explicitly constructing appropriate discrete versions of constitutive relations, called Hodge--star operators. Several alternatives based on both global and local projection operators between spline spaces will be proposed. The appeal of the approach with respect to similar published methods is twofold: firstly, it exhibits high order convergence. Secondly, it does not rely on the geometric realization of any (topologically) dual mesh. Several numerical examples in various space dimensions will be employed to validate the central ideas of the proposed approach and compare its features with the standard Galerkin approach in Isogeometric Analysis.

description: We consider a two-dimensional weakly interacting ultracold Bose gas whose constituents are two-level atoms. We study the effects of a synthetic density-dependent gauge field that arises from laser-matter coupling in the adiabatic limit with a laser configuration such that the single-particle zero-order vector potential corresponds to a constant synthetic magnetic field. We find a new exotic type of current non-linearity in the Gross-Pitaevskii equation which affects the dynamics of the order parameter of the condensate. We investigate the rotational properties of this system, focusing in particular on the physical conditions that make the nucleation of a quantized vortex in the system energetically favourable with respect to the non rotating solution. We point out that two different physical interpretations can be given to this new non linearity: firstly it can be seen as a local modification of the mean field coupling constant, whose value depends on the angular momentum of the condensate. Secondly, it can be interpreted as a density modulated angular velocity given to the cloud. Looking at the problem from both of these viewpoints, we analyze the physical conditions that make a single vortex state energetically favourable. In the Thomas-Fermi limit, we show that the effect of the new nonlinearity is to induce a rotation to the condensate, where the transition from non-rotating to rotating states depends on the density of the cloud.

description: This work presents a computational formulation of the Bayesian maximum entropy (BME) approach to solve a stochastic partial differential equation (PDE) representing the advection-reaction process across space and time. The solution approach provided by BME has some important features that distinguish it from most standard stochastic PDE techniques. In addition to the physical law, the BME solution can assimilate other sources of general and site-specific knowledge, including multiple-point nonlinear space/time statistics, hard measurements, and various forms of uncertain (soft) information. There is no need to explicitly solve the moment equations of the advection-reaction law since BME allows the information contained in them to consolidate within the general knowledge base at the structural (prior) stage of the analysis. No restrictions are posed on the shape of the underlying probability distributions or the space/time pattern of the contaminant process. Solutions of nonlinear systems of equations are obtained in four space/time dimensions and efficient computational schemes are introduced to cope with complexity. The BME solution at the prior stage is in excellent agreement with the exact analytical solution obtained in a controlled environment for comparison purposes. The prior solution is further improved at the integration (posterior) BME stage by assimilating uncertain information at the data points as well as at the solution grid nodes themselves, thus leading to the final solution of the advection-reaction law in the form of the probability distribution of possible concentration values at each space/time grid node. This is the most complete way of describing a stochastic solution and provides considerable flexibility concerning the choice of the concentration realization that is more representative of the physical situation. Numerical experiments demonstrated a high solution accuracy of the computational BME approach. The BME approach can benefit from the use of parallel processing (the relevant systems of equations can be processed simultaneously at each grid node and multiple integrals calculations can be accelerated significantly, etc.).
Uniform Proofs of Normalisation and Approximation for Intersection Types

description: We present intersection type systems in the style of sequent calculus, modifying the systems that Valentini introduced to prove normalisation properties without using the reducibility method. Our systems are more natural than Valentini's ones and equivalent to the usual natural deduction style systems. We prove the characterisation theorems of strong and weak normalisation through the proposed systems, and, moreover, the approximation theorem by means of direct inductive arguments. This provides in a uniform way proofs of the normalisation and approximation theorems via type systems in sequent calculus style.

description: John Murdoch Mitchison, known as Murdoch, was elected FRS in recognition of his work on the cell cycle. This emerged from a lifelong interest in the natural sciences, interrupted by war-time work in Operational Research which developed his critical appraisal of research technique. Post-war, he completed a PhD at Cambridge, then worked with Sir Michael Swann FRS (1962) on mitotic membrane changes in sea urchins. In 1953 Murdoch joined the University of Edinburgh Zoology Department and in time switched his interest to the fission yeast Schizosaccharomyces pombe. Over the next 30 years he investigated cell growth and division, employing a meticulous approach to experiments. He considered there to be a ‘growth cycle’ in cells, independent of the DNA-division cycle. There is experimental evidence to support this idea, but further investigations of it have been limited.Actively fostering a relaxed but industrious and enquiring ethos in the lab, Murdoch ran the department jointly with Aubrey Manning. The Mitchison group's work at Edinburgh attracted students including Paul Nurse (later Sir Paul Nurse; FRS 1989, PRS 2010–2015), Béla Novak, Kim Nasmyth (FRS 1989) and Peter Fantes as well as many visiting academics. Murdoch's work on S. pombe came to both national and international recognition, forming a foundation for the current thriving community of researchers in cell physiology, cell genetics and molecular biology.Murdoch is remembered for his single-minded commitment to cell biology research and his generous, fair-minded support of younger colleagues and students. He was, additionally, an expert landscape gardener, a convivial host and phenomenally well-informed on most subjects.

title: A New Eight-Grade Piano Curriculum for Students with an Arab Background: A Cross-Cultural Adaptation of the ABRSM Piano Syllabi
Creators: name: Momani, Maria
Publisher: name: University of Liverpool Repository
Year: 2024

description: Like their peers in other Arab countries, a considerable number of Jordanian piano students experience difficulties when engaging with Western Classical music repertoire due to lack of exposure to it, particularly its polyphonic construction. Given that Western music is the dominant repertoire used in piano learning, Arab piano students often find the learning process challenging, which leads to decreased motivation to learn the instrument. This, in turn, stifles and prolongs their musical development. The theories that underlie this research draw from the work of prominent scholars in the fields of education and health care to better understand how students learn. Their studies support the assertion that motivation is a crucial component of the learning process. Using an analytical approach, piano techniques were extracted from the body of ABRSM practical exam syllabi from 2011–2012 to 2017–2018 and combined with Arabic melodies (in collaboration with a professional composer) to produce twenty-nine new cross-cultural pieces from Grade 1 to 8. Additionally, an evaluative study was carried out to explore the impact of this curriculum on piano students in Jordan, and the results generally showed an increase in motivation and a level of technical challenge that is consistent with ABRSM curricula. The aim of this project is to overcome the cultural barriers that impede the development of potential for Arabic piano students by proposing a cross-cultural adaptation of the ABRSM piano curriculum that integrates Arabic music (both traditional and contemporary). This new eight-grade curriculum is comprehensive with respect to performance technique and has the same structured gradual levels of challenge that are derived from the ABRSM system. This new curriculum will help Arabic students to develop the proper pianistic technique through familiar, meaningful, and interesting repertoire. Furthermore, a full reference of techniques is included in a table which may serve as a database for composers, educators, and music teachers worldwide in creating more works of this kind in order to increase motivation and enjoyment in instrumental learning and thus encourage learners to continue their musical studies.
Consistent thermodynamic formulations for multiscale hydrologic systems: Fluid pressures

description: 1] Although averaging procedures to derive larger-scale conservation equations from their microscopic counterparts have been examined and employed in a consistent manner for a range of hydrologic problems, procedures for obtaining correspondingly averaged thermodynamic relations at the larger scale have received less attention. We examine issues related to the change of scale for intensive thermodynamic quantities, such as fluid pressures and temperatures, compare formulations based upon the underlying thermodynamic theory relied upon, and produce precise, consistent definitions for fluid pressures and capillary pressures in multiphase porous medium systems. The averaged thermodynamics approach demonstrated and advocated is applicable to a wide range of hydrologic systems beyond the two-fluid porous medium case examined in detail in this work.
