title: Exploring strategies for developing Western classical music education in the Sultanate of Oman
Creators: name: Aljabri, K.
Publisher: name: Royal College of Music
Year: 2017

description: The initial aim of this research was to assess whether it was possible to introduce Western Classical Music (WCM) into the Omani school music curriculum. Oman is a model for establishing, firstly, whether it is possible to introduce WCM to a school regime in which it has never previously existed and, secondly, how such an introduction can be most effectively implemented. There was no published research in this area and, as this research developed, the initial stance evolved and modified, leading to broader conclusions. This has implications not only for music education in Oman but also for wider discussions about the role of WCM in non-Western music education and its potential expansion in non-traditional spheres. The thesis reports on both the cultural and historical context of
music and music education in Oman, as well as the attitude of Omani Islam to the permissibility of music within an Islamic state.
Previous global attempts to introduce alien musical traditions into their curricula are reviewed to establish what lessons might be learned alongside the educational models and approaches adopted within English schools. The English observations are used to design investigative pilot schemes (including alternative pedagogies), which were conducted within four Omani state schools. Throughout the thesis, qualitative research makes use of ethnographically informed case studies and five research methods: semi-structured interviews, surveys, participant observation, field notes and documentation. Data are analysed thematically and via descriptive synthesis in order to identify key concepts and themes and, thus, to arrive at holistic strategies for a potential introduction of WCM into the National Curriculum (NC).
Findings suggest that it is possible to introduce WCM into an outward-looking country with links to external governments and an established music scene. Religious reservations were largely overcome by public debate while cultural resistance was soothed by an emphasis on the equal status of national music alongside non-native music education. Observations in English schools found that learning outcomes are dependent on a number of factors including the individual ability of each teacher, teaching resources and a receptive environment. The Omani pilots, in turn, suggest that the incorporation of WCM into the NC requires additional elements such as cultural sensitivity, detailed planning and
comprehensive, open debate. Additionally, it was not the musical genre that created the successful outcomes but, rather, the pedagogy. The desired outcome, therefore, was not to effect the introduction of WCM into the Omani national music curriculum per se but to open up the school music curriculum to a more progressive model of pedagogy. This
research has implications for the introduction and expansion of new musical genres into National Curricula.

description: We show that a QWEP von Neumann algebra has the weak* positive approximation property if and only if it is seemingly injective in the following sense: there is a factorization of the identity of $M$ $$Id_M=vu: M{\buildrel u\over\longrightarrow} B(H) {\buildrel v\over\longrightarrow} M$$ with $u$ normal, unital, positive and $v$ completely contractive. As a corollary, if $M$ has a separable predual, $M$ is isomorphic (as a Banach space) to $B(\ell_2)$. For instance this applies (rather surprisingly) to the von Neumann algebra of any free group. Nevertheless, since $B(H)$ fails the approximation property (due to Szankowski) there are $M$'s (namely $B(H)^{**}$ and certain finite examples defined using ultraproducts) that are not seemingly injective. Moreover, for $M$ to be seemingly injective it suffices to have the above factorization of $Id_M$ through $B(H)$ with $u,v$ positive (and $u$ still normal).
description: A confusion between weak* separability and separability of the predual for a general von Neumann algebra has been corrected in the two places where it occured, namely Remark 1.3 and the proof of Proposition 7.1

description: We explore supersymmetric quantum quenches of the mass and coupling constants in the $\mathcal{N}=1$ supersymmetric vector model using Hartee-Fock approximation. We find that in the case of the free fermionic field, quench of the mass generates singularity localized at the instant of sudden change and we point out the essential role of the parity of spacetime. Focusing on a supersymmetric generalization of the $ϕ^6$ model and using stationary phase approximation, we demonstrate that supersymmetry is broken in the asymptotic state that emerges at late times after the quench. Finally, we confirm SUSY breaking in the time-dependent setting by integrating numerically the exact equations of motion from the instant of the quench into asymptotic regime. We argue that the breaking of supersymmetry cannot be attributed to the thermal physics since to leading order in the Hartee-Fock approximation the final state is not thermal.

The ($NUV-r$) vs. $M_r$ as a tracer of early-type galaxies evolution in USGC U376 and LGG 225 groups

description: With the aim of tracing back the evolution of galaxies in nearby groups we use smooth particle hydrodynamical (SPH) simulations with chemo-photometric implementation. Here we focus on the evolution of the early-type members (Es and S0s, ETGs hereafter) in two groups, USGC U376 and LGG 225, both in the Leo cloud. We use the near-UV (NUV)-optical rest-frame $NUV-r$ versus $M_r$ color magnitude diagram to follow their evolution, from the blue cloud (BC) to the red sequence (RS), through the green valley (GV). ETGs brighter than $M_r=-21$ mag are older than 13 Gyr and spend up to 10 Gyr of their overall evolutionary time in the BC before they reach the RS migrating through the GV. Fainter ETGs are younger, of about 2 Gyr on average, and evolve for about 7-8 Gyr along the BC. The turn-off occurs at z ~ 0.3-0.4. Therefore these ETGs spend up to 3-5 Gyr crossing the GV; UGC 06324, the faintest ETG in the sample, still is in the GV. The mechanism driving their evolution is gravitational, due to merging and/or interaction. Our SPH simulations suggest that ETG members of these groups evolved toward the RS before and during the group collapse phase. This result is consistent with the dynamical analysis of both groups showing that they are not yet virialized.

description: This study aims to explore the trends and characteristics of clinical studies on LBP within the World Health Organization (WHO) International Clinical Trials Registry (ICTRP) platform. The primary objective is to understand how registration practices have evolved over time to address challenges in the LBP literature, aligning with the broader movement towards open science, and comparing registration patterns between interventional and observational studies. Specifically, the study will evaluate the characteristics of registered research (e.g., design, sample size, location, source of support), identify the overall trend in LBP study registration globally, compare it with published studies, and assess registration timing (prospective or retrospective) and Individual Participant Data (IPD) sharing statements among registered studies to gauge the openness of LBP research.

description: We report on the setup and initial discoveries of the Northern High Time Resolution Universe survey for pulsars and fast transients, the first major pulsar survey conducted with the 100-m Effelsberg radio telescope and the first in 20 years to observe the whole northern sky at high radio frequencies. Using a newly developed 7-beam receiver system combined with a state-of-the-art polyphase filterbank, we record an effective bandwidth of 240 MHz in 410 channels centred on 1.36 GHz with a time resolution of 54 $μ$s. Such fine time and frequency resolution increases our sensitivity to millisecond pulsars and fast transients, especially deep inside the Galaxy, where previous surveys have been limited due to intra-channel dispersive smearing. To optimise observing time, the survey is split into three integration regimes dependent on Galactic latitude, with 1500-s, 180-s and 90-s integrations for latitude ranges $|b|<3.5^{\circ}$, $|b|<15^{\circ}$ and $|b|>15^{\circ}$, respectively. The survey has so far resulted in the discovery of 15 radio pulsars, including a pulsar with a characteristic age of $\sim18$ kyr, {PSR J2004+3429}, and a highly eccentric, binary millisecond pulsar, {PSR J1946+3417}. All newly discovered pulsars are timed using the 76-m Lovell radio telescope at the Jodrell Bank Observatory and the Effelsberg radio telescope. We present timing solutions for all newly discovered pulsars and discuss potential supernova remnant associations for {PSR J2004+3429}.

The Aeration of Activated Sludge Mixtures

description: The purpose of this investigation is to establish, to the extent possible, the effect of degree aeration on several characteristics of a sewage-sludge mixture: principally, the oxygen utilization by an activated sludge after varying periods of aeration, with varying amounts of air supplied;
and secondly, the effect of aeration periods of activated sludges on clarification and dissolved oxygen content.

The work was performed at the Tri-City Sewage Treatment Plant, in Alhambra, California (commonly referred to as the Pasadena Sewage Treatment Plant). Tests were run on samples taken from the new aeration and clarification unit used in conjunction with the original activated sludge plant. These tests were made in the laboratory of the plant.

Tests were begun in January, 1938 and continued until May, 1938, with one interruption, that caused by the floods of early March. The operation of the plant was affected considerably by this flood, and normalcy was not restored until the middle of May. However, the school year necessitated the termination of testing in early May.

Unlike most experimental work, the time the tests are performed is in the case of tests run on actual sewage flows extremely important. Early morning flows are small and weak, rising sharply during later morning hours in both quantity of flow and strength of sewage. But due to the exigencies
of scheduled work at the Institute, it was not possible to be at the plant at the requisite hours regularly.
There were several occasions where we deemed it necessary to run our tests for twelve consecutive hours, but these were seldom possible.
The effect of the change in flow and strength, together with other time factors are treated later in the paper.

description: We introduce a method to numerically compute equilibrium measures for problems with attractive-repulsive power law kernels of the form $K(x-y) = \frac{|x-y|^α}α-\frac{|x-y|^β}β$ using recursively generated banded and approximately banded operators acting on expansions in ultraspherical polynomial bases. The proposed method reduces what is naively a difficult to approach optimization problem over a measure space to a straightforward optimization problem over one or two variables fixing the support of the equilibrium measure. The structure and rapid convergence properties of the obtained operators results in high computational efficiency in the individual optimization steps. We discuss stability and convergence of the method under a Tikhonov regularization and use an implementation to showcase comparisons with analytically known solutions as well as discrete particle simulations. Finally, we numerically explore open questions with respect to existence and uniqueness of equilibrium measures as well as gap forming behaviour in parameter ranges of interest for power law kernels, where the support of the equilibrium measure splits into two intervals.

description: In this letter, we consider two sets of observations defined as subspace signals embedded in noise and we wish to analyze the distance between these two subspaces. The latter entails evaluating the angles between the subspaces, an issue reminiscent of the well-known Procrustes problem. A Bayesian approach is investigated where the subspaces of interest are considered as random with a joint prior distribution (namely a Bingham distribution), which allows the closeness of the two subspaces to be adjusted. Within this framework, the minimum mean-square distance estimator of both subspaces is formulated and implemented via a Gibbs sampler. A simpler scheme based on alternative maximum a posteriori estimation is also presented. The new schemes are shown to provide more accurate estimates of the angles between the subspaces, compared to singular value decomposition based independent estimation of the two subspaces.

description: Urban mobility is one of the main challenges of city management. Population growth, the ease of obtaining a private motor vehicle and the lack of investment in public transportation have made it difficult to move around in cities. Urban mobility by bicycle, historically popular in some countries such as Netherlands and Denmark, has gained space in Brazil in recent years. The use of the bicycle as a means of transportation brings several benefits, such as saving time in traffic, saving money, it does not pollute the environment and it is healthy. In order for cycling to be performed with quality and for the population to feel encouraged to use this vehicle, it is necessary to offer a quality infrastructure for this purpose, providing safety and well-being to the cyclist and to the other users of the road, such as pedestrians and drivers. Thus, the objective of this study is the planning of a cycle route for the Vale do Aço region, which connects the centers of its three main cities, Ipatinga, Coronel Fabriciano and Timóteo, aiming to promote sustainable urban mobility by bicycle through the implantation of an adequate infrastructure, according to standards and manuals, with regard to paving, signaling, drainage and lighting, as well as special items for bicycles, such as bicycle racks and bicycle parking lots. The preliminary study evaluated the characteristics of the existing infrastructure in the path traced to the route through a method of rapid evaluation of cycle paths, and through the analysis of the results, solutions were presented for each section of the route.

India, China, Hong Kong, and Japan. The task force met via Zoom once a month during the year 2022, with assignments after each meeting, whereby members wrote about the situation of anthropologists in their own societies. Initially, the task force focused on the impact of citation indexes such as the Social Science Citation Index on promotion practices for anthropologists in our different societies; but we soon realized that SSCI was only one factor in how anthropologists were being evaluated, and so we began to examine the more general situations of anthropologists in our different societies. This is the document we have come up with. The chief limitation of this document is that it covers a small range of societies, albeit from a wide geographic range around the world. It is also limited by the fact that different members of the task force joined at different times, leading to some degree of inconstistency in the data presented. We hope that in subsequent versions of this document, we can cover many more societies, to arrive at a full portrayal of the situations of anthropologists everywhere in the world. We look forward to your comments on this document!
Fluctuating local moments, itinerant electrons and the magnetocaloric effect: the compositional hypersensitivity of FeRh

description: We describe an ab-initio Disordered Local Moment Theory for materials with quenched static compositional disorder traversing first order magnetic phase transitions. It accounts quantitatively for metamagnetic changes and the magnetocaloric effect. For perfect stoichiometric B2-ordered FeRh, we calculate the transition temperature of the ferromagnetic-antiferromagnetic transition to be $T_t =$ 495K and a maximum isothermal entropy change in 2 Tesla of $|ΔS|= 21.1$ J~K$^{-1}$~kg$^{-1}$. A large (40\%) component of $|ΔS|$ is electronic. The transition results from a fine balance of competing electronic effects which is disturbed by small compositional changes - e.g. swapping just 2\% Fe of `defects' onto the Rh sublattice makes $T_t$ drop by 290K. This hypersensitivity explains the narrow compositional range of the transition and impurity doping effects.

Reformulates statistical mechanics in terms of pure states and shows that (a) quantum statistics of typical pure states are very close to the mechanics of statistical mechanical ensembles; (b) if a system is in a typical state with energy E, then the reduced density matrix of a subsystem is very close to a thermal state. (A similar result was derived using Levy's lemma some years later by S. Popescu, A.J. Short, A.Winter, Nature Physics 2, 754-758 (2006).) Pure state quantum statistical mechanics is applied to black holesto show that for typical states of matter insideand outside a black hole, the external state is likely to be thermal. Proposes novel interpretation of probabilities in quantum statistical mechanics. Full thesis available at http://meche.mit.edu/documents/slloyd_thesis.pdf.

title: The vocality of the dramatic soprano voice in Richard Strauss's Salome and Elektra
Creators: name: McHugh, E. R.
Publisher: name: Royal College of Music
Year: 2018

description: This thesis explores how voice, the body, and gender interact to characterise the eponymous leading roles in Richard Strauss’s Salome (1905) and Elektra (1909). Approaching the vocality of the two title characters from the perspective of a performer, I use vocal line as notated in the score as a basis for exploring constructions of women at the time these two operas were composed. Because these operas were created during the fin-de-siècle, they occupy a crucial transitional point between Romantic and Modern vocal writing, when, in contrast to the practices of the bel canto era, the singer was expected to demonstrate ever-greater fidelity to the notated score. Therefore, the voice is largely manipulated by another (the composer) to perform sounds that construct her identity, and hence, her gender. I expand upon this absolute to show how in these operas, gender performativity is manifested in the musical notation.
The operatic soprano voice, when manipulated for certain effects, performs ‘conventional’ aspects of a female character’s gender (for example, its pitch range), but I argue it also has the ability to communicate something more visceral, something that transcends gender norms, and also language itself. Building on a wide range of analytical and critical discourses ranging from gender theory to vocal technique, my thesis explores how a soprano singer navigates the extreme vocality present in these two operas, and in the process articulates a range of constructions of identity of women in the fin-de-siècle. In analysing the vocal writing of these two works, it becomes apparent that gender dichotomies are effectively voided in passages within these seminal operas, which nevertheless comment directly on fin-de-siècle ‘femininity’ or ‘masculinity’.
My research analyses vocal gestures from a technical standpoint and, in so doing, suggests that gender norms become obsolete at those crucial moments in which voice and body are pushed to physical and expressive limits.

description: We present a neural modeling framework for Non-Line-of-Sight (NLOS) imaging. Previous solutions have sought to explicitly recover the 3D geometry (e.g., as point clouds) or voxel density (e.g., within a pre-defined volume) of the hidden scene. In contrast, inspired by the recent Neural Radiance Field (NeRF) approach, we use a multi-layer perceptron (MLP) to represent the neural transient field or NeTF. However, NeTF measures the transient over spherical wavefronts rather than the radiance along lines. We therefore formulate a spherical volume NeTF reconstruction pipeline, applicable to both confocal and non-confocal setups. Compared with NeRF, NeTF samples a much sparser set of viewpoints (scanning spots) and the sampling is highly uneven. We thus introduce a Monte Carlo technique to improve the robustness in the reconstruction. Comprehensive experiments on synthetic and real datasets demonstrate NeTF provides higher quality reconstruction and preserves fine details largely missing in the state-of-the-art.

description: The BiS2-based superconductors were discovered recently. The superconductivity has been proved by many other groups. Since the previous experiments were all done on polycrystalline samples, therefore there remains a concern whether the superconductivity is really derived from the materials intrinsically or from some secondary phases. Experiments on single crystals are highly desired. In this paper, we report the successful growth of the NdO1-xFxBi1-yS2 single crystals. Resistive and magnetic measurements reveal that the bulk superconducting transition occurs at about 5 K, while an unexpected giant superconducting fluctuation appears at temperatures as high as 2-4 kBTC. Analysis based on the anisotropic Ginzbaug-Landau theory gives an anisotropy of 30-45. Two gap features with magnitudes of about 3.5+-0.3 meV and 7.5+-1 meV were observed by scanning tunneling spectroscopy. The smaller gap is associated with the bulk superconducting transition at about 5 K yielding a huge ratio 2Delta_s/kBTc =16.8, the larger gap remains up to about 26 K. The normal state recovered by applying a high magnetic field shows an anomalous semiconducting behavior. All these suggest that the superconductivity in this newly discovered superconductor cannot be formatted into the BCS theory.

description: Loneliness is a perceived discrepancy between desired and experienced social relationships, which may arise from perceived lack of intimate attachment to another person (e.g., friend) or lack of involvement in larger networks (e.g., peer groups). The current study examined and compared how different aspects of friendship and peer group involvement predicted loneliness of Indonesian adolescents. Participants were 754 twelfth-grade Indonesian students (413 girls, mean age = 16.5 years). Loneliness was self-reported. Reciprocated friendships were calculated from within-grade nominations and friendship quality was obtained from ratings pertaining to each nominated friend. Peer groups were generated from Social Cognitive Mapping (SCM) and status indices were calculated from SCM and peer nominations. A concurrent SEM model was tested where quantity and self- and friend-perceived quality of friendship, group membership (i.e., within-group centrality), and status of the group in the larger network (i.e., group centrality status and group popularity status) predicted loneliness. All predictors had unique negative effects on loneliness with generally similar effect sizes except for friend-perceived friendship quality. An interaction between within-group centrality and group popularity status was found for boys. The results revealed that quantity and quality of friendship as well as position in the peer group and the status of the peer group were associated with loneliness. Being central in a group may be more important for those in low-status groups than high-status groups. Group-related indices were comparable to friendship indices as predictors of loneliness, which may be shaped by Indonesian culture where group involvement is valued more than intimate friendships.

Policy Brief: Accelerating agroecology transition using living labs: policy enablers and barriers

description: In Europe, policy enablers for agroecology transition with living labs as key research and innovation mechanisms include: adequate research funding and priorities, policy directions and advisory support. These enablers affect abilities to structure and operate living labs.
Low quality or absence of these enablers renders them barriers to transition. There is considerable geographical variation: barriers are most notable in Southern and Eastern parts of Europe. Policy siloes and a lack of systems thinking in policy is a barrier across Europe.
Agricultural knowledge and innovation systems (AKIS) are central to supporting living labs. AKIS are composed of farmers and their organisations, research and advisory systems.
However, the capacities of AKIS' across Europe to support the development of living labs vary considerably. Differentiated approaches are needed to strengthen the capacity of AKIS, and should focus on geographical 'hotspots' where AKIS are particularly weak.

description: We investigate numerically the behavior of the compensation temperature, $T_{comp}$, in ferrimagnetic multilayer in the type $3(S_{1-x} σ_x)/σ$ with respect to the increase of the spin concentration $σ_x$, which are randomly distributive in a mix of spins $S = 0, \pm 1$ and $σ= \pm 1/2$, with ferromagnetic interaction between spins of the same type, and antiferromagnetic interaction for spins of different type. We have found that $T_{comp}$ decrease slowly with the increase of $x$, until $σ_x$ represent a little more than 40\% of the spin mixture. For higher concentration values $T_{comp}$ drops abruptly and disappears, as predicted by experimental result.

description: We investigate the behavior of Fourier transforms for a wide class of nonstationary nonlinear processes. Asymptotic central and noncentral limit theorems are established for a class of nondegenerate and degenerate weighted $V$-statistics through the angle of Fourier analysis. The established theory for $V$-statistics provides a unified treatment for many important time and spectral domain problems in the analysis of nonstationary time series, ranging from nonparametric estimation to the inference of periodograms and spectral densities.

Mechanistic insights of the interaction of taxifolin with transcriptional regulator LasR of Pseudomonas aeruginosa using molecular modeling techniques

description: Pseudomonas aeruginosa is one of the most dangerous superbugs and is responsible for both acute and chronic infection. Current therapies are not effective because of biofilms that increase antibiotic resistance. Bacterial virulence and biofilm formation are regulated through a  system called quorum sensing, which includes transcriptional regulators LasR and RhIR. These regulators are activated by their own natural autoinducers. Targeting this system is a promising strategy to combat bacterial pathogenicity. Flavonoids are very well known for their antimicrobial activity and taxifolin is one of them. It is also known that flavonoids inhibit Pseudomonas aeruginosa biofilm formation, but the mechanism of action is unknown. In the present study, we tried to analyse the mode of interactions of LasR with taxifolin. We used a combination of molecular docking, molecular dynamics simulations and machine learning techniques, which includes principal component and cluster analysis to study the interaction of the LasR protein with taxifolin. We show that taxifolin has two binding modes. One binding mode is the interaction with ligand binding domain. The second mode is the interaction with the “bridge”, which is a cryptic binding site. It involves conserved amino acid interactions from multiple domains. Biochemical studies show hydroxyl group of ring A in flavonoids is necessary for inhibition. In our model the hydroxyl group ensures the formation of many hydrogen bonds during the second binding mode. Microsecond simulations also show the stability of the formed complex. This study may offer insights on how taxifolin inhibits LasR and the quorum sensing circuitry.

Marine renewable energy

description: The Lab Upgrade Point Absorber (LUPA) is an open-source wave energy converter designed and tested by Oregon State University. The computer-aided design (CAD) files are provided here in two forms: the original SOLIDWORKS (2021) model as "LUPA SOLIDWORKS.zip" and as a STEP file "LUPA-A1000.step". The bill of materials is provided as an Excel file with assemblies (LUPA-Axxx), part numbers (LUPA-Axxx-Pyyy), part descriptions, manufacturers, and manufacturer part numbers. This comprehensive CAD model represents LUPA as it was deployed in Fall 2022 testing at the O.H. Hinsdale Wave Research Laboratory. The mass properties including mass, center of gravity, and moments of inertia have been overridden for some parts and assemblies to match the physical device properties as determined from experiments. This appears as "overridden by user" when viewing mass properties in SOLIDWORKS. The LUPA-A1000.SLDASM file from the LUPA SOLIDWORKS.zip folder is the topmost assembly, open this file to see the entire model as one assembly. See https://pmec-osu.github.io/LUPA/ for more information on LUPA.
Acoustic confinement and Stimulated Brillouin Scattering in integrated optical waveguides

description: We examine the effect of acoustic mode confinement on Stimulated Brillouin Scattering in optical waveguides that consist of a guiding core embedded in a solid substrate. We find that SBS can arise due to coupling to acoustic modes in three different regimes. First, the acoustic modes may be guided by total internal reflection; in this case the SBS gain depends directly on the degree of confinement of the acoustic mode in the core, which is in turn determined by the acoustic V-parameter. Second, the acoustic modes may be leaky, but may nevertheless have a sufficiently long lifetime to have a large effect on the SBS gain; the lifetime of acoustic modes in this regime depends not only on the contrast in acoustic properties between the core and the cladding, but is also highly dependent on the waveguide dimensions. Finally SBS may occur due to coupling to free modes, which exist even in the absence of acoustic confinement; we find that the cumulative effect of coupling to these non-confined modes results in significant SBS gain. We show how the different acoustic properties of core and cladding lead to these different regimes, and discuss the feasibility of SBS experiments using different material systems.

description: We study inelastic neutrino scattering off hot nuclei for temperatures relevant under supernova conditions. The method we use is based on the quasiparticle random phase approximation extended to finite temperatures within the thermo field dynamics (TQRPA). The method allows a transparent treatment of upward and downward transitions in hot nuclei, avoiding the application of Brink's hypothesis. For the sample nuclei $^{56}$Fe and $^{82}$Ge we perform a detailed analysis of thermal effects on the strength distributions of allowed Gamow-Teller (GT) transitions which dominate the scattering process at low neutrino energies. For $^{56}$Fe and $^{82}$Ge the finite temperature cross-sections are calculated by taking into account the contribution of allowed and forbidden transitions. The observed enhancement of the cross-section at low neutrino energies is explained by considering thermal effects on the GT strength. For $^{56}$Fe we compare the calculated cross-sections to those obtained earlier from a hybrid approach that combines large-scale shell-model and RPA calculations.

description: The energy recovery linac test facility (ERL-TF), a compact ERL-FEL (free electron laser) two-purpose machine, was proposed at the Institute of High Energy Physics, Beijing. As one important component of the ERL-TF, the photo-injector started with a photocathode direct-current gun has been designed. In this paper optimization of the injector beam dynamics in low-charge operation mode is performed with iterative scans using Impact-T. In addition, the dependencies between the optimized beam quality and the initial offset at cathode and element parameters are investigated. The tolerance of alignment and rotation errors is also analyzed.

description: We introduce and study the \emph{Rademacher-Carlitz polynomial} \[ \RC(u, v, s, t, a, b) := \sum_{k = \lceil s \rceil}^{\lceil s \rceil + b - 1} u^{\fl{\frac{ka + t}{b}}} v^k \] where $a, b \in \Z_{>0}$, $s, t \in \R$, and $u$ and $v$ are variables. These polynomials generalize and unify various Dedekind-like sums and polynomials; most naturally, one may view $\RC(u, v, s, t, a, b)$ as a polynomial analogue (in the sense of Carlitz) of the \emph{Dedekind-Rademacher sum} \[ \r_t(a,b) := \sum_{k=0}^{b-1}\left(\left(\frac{ka+t}{b} \right)\right) \left(\left(\frac{k}{b} \right)\right), \] which appears in various number-theoretic, combinatorial, geometric, and computational contexts. Our results come in three flavors: we prove a reciprocity theorem for Rademacher-Carlitz polynomials, we show how they are the only nontrivial ingredients of integer-point transforms \[ σ(x,y):=\sum_{(j,k) \in \mathcal{P}\cap \Z^2} x^j y^k \] of any rational polyhedron $\mathcal{P}$, and we derive a novel reciprocity theorem for Dedekind-Rademacher sums, which follows naturally from our setup.
