description: Triangulations are an ubiquitous input for the finite element community. However, most raw triangulations obtained by imaging techniques are unsuitable as-is for finite element analysis. In this paper, we give a robust pipeline for handling those triangulations, based on the computation of a one-to-one parametrization for automatically selected patches of input triangles, which makes each patch amenable to remeshing by standard finite element meshing algorithms. Using only geometrical arguments, we prove that a discrete parametrization of a patch is one-to-one if (and only if) its image in the parameter space is such that all parametric triangles have a positive area. We then derive a non-standard linear discretization scheme based on mean value coordinates to compute such one-to-one parametrizations, and show that the scheme does not discretize a Laplacian on a structured mesh. The proposed pipeline is implemented in the open source mesh generator Gmsh, where the creation of suitable patches is based on triangulation topology and parametrization quality, combined with feature edge detection. Several examples illustrate the robustness of the resulting implementation.

description: Part one of this research report explored what the literature has to say about the ways in which songs, song games and music may support the language and literacy development of young, non-English speaking children. Findings from that review indicated that music and movement can be a powerful tool to introduce, teach and reinforce curricular and abstract concepts. Part two of this research report identified appropriate music and movement resources and strategies that early childhood educators can use with non-English speaking kindergarten children to support language and literacy development.

description: In this comprehensive study, the influence of (i) material specific properties (e.g., molecular weight, zero shear viscosity, D-content) and (ii) process parameters (e.g., saturation temperature, -time, -pressure, and pressure drop rate) on the expansion behavior during the autoclave foaming process were investigated on linear Polylactide (PLA) grades, to identify and evaluate the foam relevant parameters. Its poor rheological behavior is often stated as a drawback of PLA, that limits its foamability. Therefore, nine PLA grades with different melt strength and zero shear viscosity were systematically chosen to identify whether these are the main factors governing the foam expansion and whether there is a critical value for these rheological parameters to be exceeded, to achieve low density foams with fine cells. With pressure drop induced batch foaming experiments, it could be shown that all of the investigated PLA grades could be foamed without the often used chemical modifications, although with different degrees of expansion. Interestingly, PLAs foaming behavior is rather complex and can be influenced by many other factors due to its special nature. A low molecular weight combined with a high ability to crystallize only lead to intermediate density reduction. In contrast, a higher molecular weight (i.e., increased zero shear viscosity) leads to significant increased expandability independent from the D-content. However, the D-content plays a crucial role in terms of foaming temperature and crystallization. Furthermore, the applied process parameters govern foam expansion, cell size and crystallization.

description: We introduce and discuss a new approach to the phase retrieval of fields radiated by continuous aperture sources having a circular support, which is of interest in many applications including the detection of shape deformations on reflector antennas. The approach is based on a decomposition of the actual 2-D problem into a number of 1-D phase retrieval problems along diameters and concentric rings of the visible part of the spectrum. In particular, the 1-D problems are effectively solved by using the spectral factorization method, while discrimination arguments at the crossing points allows to complete the retrieval of the 2-D complex field. The proposed procedure, which just requires a single set of far field amplitudes, takes advantage from up to now unexplored field properties and it is assessed in terms of reflector aperture fields.

Abstract Baloxavir marboxil (Xofluza®; hereafter referred to as baloxavir), the prodrug of baloxavir acid, is a first-in-class, small molecule inhibitor of the polymerase acidic (PA) protein subunit of the influenza virus polymerase complex. Baloxavir (after conversion to baloxavir acid) acts to block influenza virus replication by inhibiting the cap-dependent endonuclease activity of the PA protein. Taken orally as a single dose, baloxavir is approved in the USA for the treatment of acute uncomplicated influenza in patients ≥ 12 years of age who have been symptomatic for ≤ 48 h. Data from randomized, double-blind, placebo- and oseltamivir-controlled phase III trials have shown that baloxavir is efficacious in improving influenza symptoms both in otherwise healthy adolescents and adults and in those at high risk of influenza complications, displaying similar efficacy to that of oseltamivir. Furthermore, there is evidence that baloxavir can reduce influenza viral load more rapidly than oseltamivir. Baloxavir has activity against influenza A and B viruses (including strains resistant to neuraminidase inhibitors) and is well tolerated. Evidence of the emergence and likely human-to-human transmission of variant viruses with reduced susceptibility to baloxavir highlights the importance of monitoring and surveillance for changes in influenza virus drug susceptibility patterns. However, currently available evidence suggests that baloxavir, with the benefits of a single oral dose regimen, provides a useful alternative to neuraminidase inhibitors for the treatment of acute uncomplicated influenza in adolescents and adults.

Brane classical and quantum cosmology from an effective action

description: Motivated by the Randall-Sundrum brane-world scenario, we discuss the classical and quantum dynamics of a (d+1)-dimensional boundary wall between a pair of (d+2)-dimensional topological Schwarzschild-AdS black holes. We assume there are quite general -- but not completely arbitrary -- matter fields living on the boundary ``brane universe'' and its geometry is that of an Friedmann-Lemaitre-Robertson-Walker (FLRW) model. The effective action governing the model in the mini-superspace approximation is derived. We find that the presence of black hole horizons in the bulk gives rise to a complex action for certain classically allowed brane configurations, but that the imaginary contribution plays no role in the equations of motion. Classical and instanton brane trajectories are examined in general and for special cases, and we find a subset of configuration space that is not allowed at the classical or semi-classical level; these correspond to spacelike branes carrying tachyonic matter. The Hamiltonization and Dirac quantization of the model is then performed for the general case; the latter involves the manipulation of the Hamiltonian constraint before it is transformed into an operator that annihilates physical state vectors. The ensuing covariant Wheeler-DeWitt equation is examined at the semi-classical level, and we consider the possible localization of the brane universe's wavefunction away from the cosmological singularity. This is easier to achieve for branes with low density and/or spherical spatial sections.

title: An evaluation of the Psychoactive Substances Act 2016
Creators: name: Burgess, Nicholas Stephen
Publisher: name: University of Glasgow
Year: 2021
Subjects: subject: Drugs, criminal, law.

description: This thesis evaluates the Psychoactive Substances Act 2016 (PSA) from practical, theoretical and developmental perspectives. The PSA was created in response to the rise of New Psychoactive Substances (NPS), otherwise variously known and marketed as ‘legal highs’, ‘bath salts’, ‘research chemicals’, and ‘plant food’. In contrast to previous attempts to control recreational drugs – which individually list banned substances – the PSA employs a ‘blanket ban’ approach whereby all ‘psychoactive substances’ are proscribed, subject to limited exemptions. The Government’s review of the PSA’s operation concluded that, overall, the Act has succeeded in its main goals of: ending NPS sales; ending the game of cat and mouse (whereby new substances are created faster than the Government can ban them); reducing psychoactive substance use; and reducing psychoactive substance-related harms. Chapter one of this thesis argues that the PSA has, in fact, failed to achieve these goals. Chapter two critiques the PSA from a primarily theoretical standpoint. It is argued that the Act conflicts with numerous normative principles of criminalisation (namely harm prevention, criminalising only conduct which is wrongful, and fair labelling) and of the rule of law (namely maximum legal certainty and proportionate sentencing). It is also argued that the PSA is an illegitimate exercise of state power, and some alternative (and more appropriate) means of regulating NPS are sketched. Chapter three considers the PSA’s continuing relevance in light of political and technological developments post-enactment, and its coherence with both international and domestic drug legislation and policy. It is argued that although the Act is coherent with international and domestic drug legislation, its justificatory rationale is threatened by technological advancements, and it may soon be superseded by changing priorities at the political/policy level.

Whitney towers and gropes in 4--manifolds

Subjects: subject: Geometric Topology (math.GT)

description: Many open problems and important theorems in low-dimensional topology have been formulated as statements about certain 2--complexes called gropes. This paper describes a precise correspondence between embedded gropes in 4--manifolds and the failure of the Whitney move in terms of iterated `towers' of Whitney disks. The `flexibility' of these Whitney towers is used to demonstrate some geometric consequences for knot and link concordance connected to n-solvability, k-cobordism and grope concordance. The key observation is that the essential structure of gropes and Whitney towers can be described by embedded unitrivalent trees which can be controlled during surgeries and Whitney moves.

description: The known isospin-breaking contributions to the $K\rightarrow ππ$ amplitudes are reanalyzed, taking into account our current understanding of the quark masses and the relevant non-perturbative inputs. We present a complete numerical reappraisal of the direct CP-violating ratio $ε'/ε$, where these corrections play a quite significant role. We obtain the Standard Model prediction $\text{Re}\left(ε'/ε\right)\, =\,\left(14\,\pm\,5\right)\cdot 10^{-4}$, which is in very good agreement with the measured ratio. The uncertainty, which has been estimated conservatively, is dominated by our current ignorance about $1/N_C$-suppressed contributions to some relevant chiral-perturbation-theory low-energy constants.

description: From the latest experimental readouts in this context an intriguing discrepancy has been elicited. Indeed, theory and experiment dissent by one per cent, and though this fact could be a consequence of the mounting of the experimental device, it might also embody a difference between the way in which gravity behaves in classical and quantum mechanics. In this work the effects, upon the interference pattern, of space--time torsion will be analyzed heeding its coupling with the spin of the neutron beam. It will be proved that, even with this contribution, there is enough leeway for a further discussion of the validity of the equivalence principle in nonrelativistic quantum mechanics.

Complex time route to quantum backreaction

Subjects: subject: General Relativity and Quantum Cosmology (gr-qc)
subject: FOS: Physical sciences

description: We consider the backreaction of a quantum system $q$ on an effectively classical degree of freedom $C$ that is interacting with it. The backreaction equation based on the standard path integral formalism gives the so-called `in-out' backreaction equation, which has several serious pathologies. One can use a different backreaction prescription, referred to as the `in-in' approach, which resolves all the issues of `in-out' backreaction equation. However, this procedure is usually invoked in a rather ad hoc manner. Here we provide a rigorous path integral derivation of the `in-in' approach by exploiting the concept of quantum evolution along complex time contours. It turns out that, this approach can also be used to study both the `in-in' and `in-out' backreaction equations in a unified manner.

title: The decline of infant mortality in England and Wales, 1871-1948: a medical conundrum. The Shropshire experience - Norbury and Lydbury North Registration Sub-Districts, 1891-1902.
Creators: name: Culshaw, GM
Publisher: name: The Open University
Year: 1998

description: This research, which was conducted as part of a nation-wide project, concerns the structure of infant mortality in two rural registration sub-districts in South Shropshire during the period 1891-1902. Whereas most academic writing on the subject has been based on official statistics that do not facilitate local research, this project is based on the use of a novel primary source - the Births Registers that were kept by Vaccination Officers. In an exercise in nominal record linkage, data from this source is supplemented by information from local sources, to provide a unique, multi-faceted view of infant mortality. Research results are treated in the context of the work of other academics, with comparisons between the two sub-districts and with national statistics. Analysis is carried out in several frameworks - geographical, environmental and social. Overall annual infant mortality rates show significant fluctuations, and comparison between the rates in the sub-districts and their constituent parishes reveals marked differences, lending support to C.H. Lee’s thesis (1991) regarding the varied regional experience of infant mortality. Analysis in terms of occupation shows that differences in rates between the two sub-districts largely reflect their different social structures. The high level of neo-natal infant mortality reported by G. Newman (1906) is confirmed, and an in-depth study at family level facilitates the detailed treatment of families in which more than one infant death occurred. With a caveat concerning the small size of the statistics on which the results of this research were based, the writer concludes that the overall results show that the highest rates of infant mortality occurred mainly in poor families. This confirms the view expressed by several academics, e.g. Barbara Thompson (1984). He also suggests that the idea that family size was a significant factor in late nineteenth century infant mortality is worthy of further examination.

description: While nanoscale color generations have been studied for years, the high performance transmission structural color, simultaneously equipped with large gamut, high resolution, and optical multiplexing abilities, still remains as a hanging issue. Here, a silicon metasurface embedded Fabry-Pérot cavity is demonstrated to address this problem. By changing the planar geometries of metasurface units, the cavities provide transmission colors with 194% sRGB gamut coverage and 141111 DPI resolution, along with more than 300% enhanced angular tolerance. Such high density allows two-dimensional color mixing at diffraction limit scale. Beneficial from the polarization manipulation capacity of the metasurface, arbitrary color arrangements between cyan and red for two orthogonal linear polarizations are also realized. Our proposed cavities can be used in filters, printings, optical storages and many other applications in need of high quality and density colors.

description: Robustagramma brevicauda Cui and Marshall, new species
(Figs. 302–308, 373)
 As described for Robustagramma flavistylum except as follows.
 Body length 1.3–1.9 mm. Gena and lower frons reddish yellow; face and antenna brown. Postocellar bristle slightly shorter than postvertical bristle. Eye height ca. 2.2 times genal height. Dorsocentral bristles in 2 postsutural pairs, anterior pair similar in length to middle prescutellar acrostichal bristles. Posterodorsal katepisternal bristle half as long as distance between bristle base and wing base. Wing almost clear. Length of second costal sector ca. 0.53–0.63X length of third. Distal quarter of R 2+3 gradually curved forward (nearly straight in one male specimen from Ecuador). Discal cell with a short stump vein CuA 1.
 Male terminalia: Sternite 5 twice as long as sternite 4. Dorsomedial length of epandrium ca. 0.4X length of sternite 8. Surstylus mainly setose, with a tapering apex. Cercus exceptionally broad and short, half as long as surstylus. Distiphallus with nodes on dorsal whiplike sclerites. Postgonite with a slightly expanded, convex apex.
Female terminalia: Sternite 8 reduced to 2 small sclerites. Spermatheca with several wrinkles on distal portion, and a few spicules on basal portion.
Holotype (♂, DEBU) and paratypes (29 ♂, 58 ♀, DEBU): VENEZUELA: Bolívar. Km 40 Sta. Elena, Icabaru Rd., 100m, 4–6.viii.1986, B. Gill.
Other paratypes: Same data as holotype, but 220m (7 ♂, 19 ♀, IZAV), 1000m (13 ♂, 21 ♀, DEBU). ECUADOR: Napo. Yasuní Natl. Pk., Yasuní Res. Sta., rain forest, malaise trap, 3–20.xi.1998, Pape & Viklund (1 ♂, NHRS). Napo. 17 km NE Baeza, 1400m, dung trap, 3–6.iii.1976, S. Peck (1 ♀, DEBU). VENEZUELA: Bolívar. Quebrada de Jaspe, 19– 20.vii.1986, B. Gill (2 ♂, 9 ♀, DEBU).
Etymology: The specific epithet refers to the exceptionally short cerci of the male.
 Comments: Robustagramma brevicauda differs obviously from all of the other species of this group because the vein R 2+3 is less curved forward, and the cercus of the male is exceptionally short. Other characters of Robustagramma brevicauda leave little doubt that the species is correctly placed in the R. flavistylum group.

description: Securing an adequate supply of dispatchable resources is critical for keeping a power system reliable under high penetrations of variable generation. Traditional resource adequacy mechanisms are poorly suited to exploiting the growing flexibility and heterogeneity of load enabled by advancements in distributed resource and control technology. To address these challenges this paper develops a resource adequacy mechanism for the electricity sector utilising insurance risk management frameworks that is adapted to a future with variable generation and flexible demand. The proposed design introduces a central insurance scheme with prudential requirements that align diverse consumer reliability preferences with the financial objectives of an insurer-of-last-resort. We illustrate the benefits of the scheme in (i) differentiating load by usage to enable better management of the system during times of extreme scarcity, (ii) incentivising incremental investment in generation infrastructure that is aligned with consumer reliability preferences and (iii) improving overall reliability outcomes for consumers.

description: In policy analysis, there is a continuing tension and interplay between issues, models, and data. Issues and models have changed in recent years and there is a need for evolution in the underlying economywide economic database. We discuss accounting frameworks for integrating micro survey data with macro data from the national economic accounts. We take a modeler's perspective, arguing that new accounts are needed to support policy modeling. We discuss in detail the use of a social accounting matrix (SAM). A SAM provides a data framework which reflects an actor/transaction view of the economy and supports disaggregated economywide modeling. We discuss the relationship between a SAM and the existing national econonmic accounts for the United States, including the national income and product accounts (NIPA) and the input-output accounts.

description: Ghis report evaluates the effect of export enhancement, dollar depreciation, and a 5-percent loan rate reduction on U.S. wheat exports for the 1986/87 crop yearL-2 Depending on one's interpretation of the European Community's motivation for its own targeted subsidy program, U.S. export enhancement bonuses have likely increased the U.S. price of wheat between 7 and 22 percent, U.S. wheat export volume between 10 and 31 percent, and U.S. wheat export revenue between 18 and 61 percent. Together, a 5-percent loan rate reduction and a change in the real value of the dollar corresponding to the actual change between the fall of 1986 and 1987 would have increased U.S. wheat export volume by over 5 percent and U.S. export revenue by over 6 percent. The loan rate reduction causes a greater response in expanding wheat sales, but the exchange rate change is potentially more important for increasing U.S. wheat export revenue. The EC's comparative disadvantage in world wheat trade makes it extremely vulnerable to policies of the United States and to currency realignments.

Simple Whitney towers, half-gropes and the Arf invariant of a knot

description: A geometric characterization of the Arf invariant of a knot in the 3-sphere is given in terms of two kinds of 4-dimensional bordisms, half-gropes and Whitney towers. These types of bordisms have associated complexities class and order which filter the condition of bordism by an embedded annulus, i.e. knot concordance, and it is shown constructively that the Arf invariant is exactly the obstruction to cobording pairs of knots by half-gropes and Whitney towers of arbitrarily high class and order. This illustrates geometrically how, in the setting of knot concordance, the Vassiliev (isotopy) invariants "collapse" to the Arf invariant.

description: The local balance equations for the density, momentum, and energy of a dilute gas of elastic or inelastic hard spheres, strongly confined between two parallel hard plates are obtained. The starting point is a Boltzmann-like kinetic equation, recently derived for this system. As a consequence of the confinement, the pressure tensor and the heat flux contain, in addition to the terms associated to the motion of the particles, collisional transfer contributions, similar to those that appear beyond the dilute limit. The complexity of these terms, and of the kinetic equation itself, compromise the potential of the equation to describe the rich phenomenology observed in this kind of systems. For this reason, a simpler model equation based on the Boltzmann equation is proposed. The model is formulated to keep the main properties of the underlying equation, and it is expected to provide relevant information in more general states than the original equation. As an illustration, the solution describing a macroscopic state with uniform temperature, but a density gradient perpendicular to the plates is considered. This is the equilibrium state for an elastic system, and the inhomogeneous cooling state for the case of inelastic hard spheres. The results are in good agreement with previous results obtained directly from the Boltzmann equation.
Stress in planar cellular solids and isostatic granular assemblies: Coarse-graining the constitutive equation

description: A recent theory for stress transmission in isostatic granular and cellular systems predicts a constitutive equation that couples the stress field to the local microstructure. The theory could not be applied to macroscopic systems because the constitutive equation becomes trivial upon straightforward coarse-graining. This problem is resolved here for arbitrary planar structures. The solution is based on the observation that staggered order makes it possible to couple the stress to a reduced geometric tensor that can be coarse-grained. The method proposed here makes it possible to apply this idea to realistic systems whose staggered order is generally 'frustrated'. This is achieved by a renormalization procedure which removes the frustration and enables the use of the upscalable reduced tensor. As an example we calculate the stress due to a defect in a periodic solid foam.

description: This paper presents a spatial-temporal single harmonic switching (STHS) transmitter array architecture with enhanced efficiency in the power back-off (PBO) region. STHS is an electromagnetic and circuit co-designed and jointly optimized transmitter array that realizes beamforming and back-off power generation at the same time. The temporal dimension is originally added in STHS to achieve back-off efficiency enhancement, which can be combined with conventional power back-off enhancement methods such as Doherty amplifiers and envelope tracking. The design is validated through a simulation of a two-stage power amplifier in 65-nm CMOS at 77 GHz, which achieves a peak drain efficiency (DE) of 24.2%, a 22% DE at 3-dB PBO, 16% DE at 6-dB PBO, and 10.2% at 9-dB PBO. The efficiency exhibits a 57% improvement at 3-dB PBO, 100% improvement at 6-dB PBO, and 190% improvement at 9-dB PBO compared with class A/B amplifier.

Vortex Dynamics and Dissipation Under High-amplitude Microwave Drive

description: In this paper, we describe the vortex dynamics under high-amplitude microwave drive and its effect on the surface resistance of superconductors. The vortex surface resistance is calculated with a Montecarlo approach, where the vortex motion equation is solved for a collection of vortex flux lines each oscillating within a random pinning landscape. This approach is capable of providing a detailed description of the microscopic vortex dynamics and in turn important insights into the microwave field amplitude dependence of the vortex surface resistance. The numerical simulations are compared against experimental data of vortex surface resistance at high microwave amplitude measured by means of bulk niobium superconducting-radio frequency cavities operating at 1.3 GHz. The good qualitative agreement of simulations and experiments suggests that the non-linear dependence of the trapped flux surface resistance with the microwave field amplitude is generated by progressive microwave depinning and vortex jumps.

description: A model for ripple formation on liquid surfaces exposed to an external laser or particle beam and a variable ground is developed. The external incident beam is hereby mechanically coupled to the liquid surface due to surface roughness. Starting from the Navier Stokes equation the coupled equations for the velocity potential and the surface height are derived in a shallow-water approximation with special attention to viscosity. The resulting equations obey conservation laws for volume and momentum where characteristic potentials for gravitation and surface tension are identified analogously to conservative forces. The approximate solutions are discussed in the context of ripple formation in laser materials processing involving melting of a surface by a laser beam. Linear stability analysis provides the formation of a damped wave modified by an interplay between the external beam, the viscosity, and the surface tension. The limit of small viscosity leads to damped gravitational and the limit of high viscosity to capillary waves. The resulting wavelengths are in the order of the ripples occurring in laser welding experiments hinting to the involvement of hydrodynamic processes in their origin. By discussing the response of the system to external periodic excitations with the help of Floquet multipliers, we show that the ripple formation could be triggered by a a periodically modulated external beam, e.g. appropriate repetition rates of an incident laser beam. The weak nonlinear stability analysis provides ranges where hexagonal or stripe structures can appear. The orientation of stripe structures and ripples are shown to be dependent on the incident angle of the laser or particle beam where a minimal angle is reported. Numerical simulations confirm the findings and allow to describe the influence of variable grounds.
