description: D3.3 is the third deliverable within DAEMON WP3 documents, hence building on D3.1 and D3.2, andfocusing on near-real-time, real-time, and in-network functionalities. This deliverable outlines the final design of 13 NI solutions distributed across four WP tasks: compute-aware radio scheduling, multitimescale edge resource management, reconfigurable intelligent surfaces, and in-backhaul support for service intelligence. The document offers a high-level overview of these solutions, their alignment with the DAEMON architecture in WP2, and planned WP5 experiments for validation. Each NI solution is detailed with a WP2 requirement mapping and architectural insights, concluding with future directionsof how the WP3 footprint relates to the ongoing activities on the next generation of mobile networks.

description: Let $f:X\rightarrow X$ be a quasi-finite endomorphism of an algebraic variety $X$ defined over a number field $K$ and fix an initial point $a\in X$. We consider a special case of the dynamical Mordell-Lang Conjecture, where the subvariety $V$ contains only finitely many periodic points and does not contain any positive-dimensional periodic subvariety. We show that the set $\{n\in \mathbb{N}~|~f^n(a) \in V \}$ satisfies a strong gap principle.

Subjects: ARDL, Corruption, Healthcare delivery

description: This study economically evaluates the impact of corruption on healthcare delivery in Nigeria using secondary data sourced from the World Development Indicators from 2000-2023. The data were analyzed using ARDL bound Test for Cointegration. The findings of the first objective revealed that corruption have no significant relationship with life expectancy in Nigeria. While the findings of the second objective revealed that corruption has a positive and statistically significant relationship with infant mortality in Nigeria. This ibdicates that increase in corruption will reduce infant mortality in Nigeria. The findings of the third objective revealed that corruption have a negative and statistically significant effect on government health expenditure in Nigeria suggesting that an increase in corruption will reduce government health expenditure in Nigeria. This may be perhaps due to persistent corruption that dominated the health sector. The study recommends among others that given the negative impact of corruption on government health expenditure; targeted reforms are necessary to reduce corruption within healthcare. Strengthening transparency and accountability measures in healthcare budgeting, procurement, and service delivery can help mitigate the diversion of funds and improve healthcare investments

description: The viscosity of quantum fluids with an energy gap at zero temperature is non-dissipative and is related to the adiabatic curvature on the space of flat background metrics (which plays the role of the parameter space). For a quantum Hall fluid on two dimensional tori this viscosity is computed. In this case the average viscosity is quantized and is proportional to the total magnetic flux through the torus.

Non-Abelian Duality Based on Non-Semi-Simple Isometry Groups

Year: 1997
Subjects: subject: High Energy Physics - Theory (hep-th)
subject: FOS: Physical sciences

description: Non-Abelian duality transformations built on non-semi-simple isometry groups are analysed. We first give the conditions under which the original non-linear sigma model and its non-Abelian dual are equivalent. The existence of an invariant and non-degenerate bilinear form for the isometry Lie algebra is crucial for this equivalence. The non-Abelian dual of a conformally invariant sigma model, with non-semi-simple isometries, is then constructed and its beta functions are shown to vanish. This study resolves an apparent obstruction to the conformal invariance of sigma models obtained via non-Abelian duality based on non-semi-simple groups.

description: We use a functional renormalization group (fRG) approach to investigate potential interaction-induced instabilities in a two-dimensional model for the Dirac nodal-line materials ZrSiS and ZrSiSe employing model parameters derived from {\it ab initio} calculations. Our results confirm that the excitonic instability recently found in random-phase approximation for ZrSiS is indeed the leading instability. In the simplest modeling, spin- and charge-excitonic states are degenerate. Beyond this, we show that the fRG analysis produces an energy scale for the onset of the instability in good agreement with the experimentally observed mass enhancement. Additionally, by exploring the parameter space of the model we find that reducing the band splitting increases the instability scale and gives the chance to drive the system into an unconventional superconducting pairing state. The model parameters for the case of the structurally similar material ZrSiSe suggest the $d$-wave superconducting state as the leading instability with a very small critical scale.

As a consistency check, we derive a renormalization group relation between the N=4, N=2, and N=1 measures. We then use this relation to construct the purely bosonic (``N=0'') measure as well, in the classical approximation in which the one-loop small-fluctuations determinants is not included.

description: We analyze quantum Monte Carlo data in the vicinity of the quantum transition between a Neel state and a quantum paramagnet in a two-layer, square lattice spin 1/2 Heisenberg antiferromagnet. The real-space correlation function and the universal amplitude ratio of the structure factor and the dynamic susceptibility show clear evidence of quantum critical behavior at low temperatures. The numerical results are in good quantitative agreement with $1/N$ calculations for the $O(N)$ non-linear sigma model. A discrepancy, reported earlier, between the critical properties of the antiferromagnet and the sigma model is resolved. We also discuss the values of prefactors of the dynamic susceptibility and the structure factor in a single layer antiferromagnet at low $T$.

description: The Shafarevich conjecture for K3 surfaces asserts the finiteness of isomorphism classes of K3 surfaces over a fixed number field admitting good reduction away from a fixed finite set of finite places. André proved this conjecture for polarized K3 surfaces of fixed degree, and recently She proved it for polarized K3 surfaces of unspecified degree. In this paper, we prove a certain generalization of their results, which is stated by the unramifiedness of l-adic étale cohomology groups for K3 surfaces over finitely generated fields of characteristic 0. As a corollary, we get the original Shafarevich conjecture for K3 surfaces without assuming the extendability of polarization, which is stronger than the results of André and She. Moreover, as an application, we get the finiteness of twists of K3 surfaces via a finite extension of characteristic 0 fields.

Human Behavior and New Mobility Trends in the United States, Europe, and China

subject: Sharing Mobility

description: New mobility trends such as shared mobility, autonomous vehicles, and mobility as a service are poised to disrupt the way the world moves. Since transport behavior is rooted in human behavior, how these trends are adopted will be influenced by behavioral preferences as well as cultural trends. This literature review looks at the behavioral preferences that will influence the uptake and impact of new mobility in the three largest markets: the United States, Europe, and China. The author finds that factors such as cost, time, comfort, convenience, safety, identity creation, and environmental concern are all important in transport modal choice. Larger societal trends such as changing preferences amongst younger generations as well as differences between urban and rural riders will also influence uptake of new mobility. Ultimately, the sustainability of new mobility in terms of reduced emissions and congestion will depend upon the adoption of shared models over private car ownership, which will require behavioral changes that could be incentivized with smart public policy.

description: The identifiability of a system is concerned with whether the unknown parameters in the system can be uniquely determined with all the possible data generated by a certain experimental setting. A test of quantum Hamiltonian identifiability is an important tool to save time and cost when exploring the identification capability of quantum probes and experimentally implementing quantum identification schemes. In this paper, we generalize the identifiability test based on the Similarity Transformation Approach (STA) in classical control theory and extend it to the domain of quantum Hamiltonian identification. We employ STA to prove the identifiability of spin-1/2 chain systems with arbitrary dimension assisted by single-qubit probes. We further extend the traditional STA method by proposing a Structure Preserving Transformation (SPT) method for non-minimal systems. We use the SPT method to introduce an indicator for the existence of economic quantum Hamiltonian identification algorithms, whose computational complexity directly depends on the number of unknown parameters (which could be much smaller than the system dimension). Finally, we give an example of such an economic Hamiltonian identification algorithm and perform simulations to demonstrate its effectiveness.

description: The strength of the Yukawa coupling of the leptons and quarks with the Higgs boson is uniquely determined by the Higgs mechanism for generating masses in the Standard Model. The top-Higgs coupling can be measured directly in the process e^+e^- --> t tbar H. This process therefore provides a fundamental test of the Higgs mechanism. Extending earlier analyses carried out in the Born approximation, we have determined the cross section for this process including QCD corrections, which turn out to be important.

description: The background field method for N = 2 super Yang-Mills theories in harmonic superspace is developed. The ghost structure of the theory is investigated. It is shown that the ghosts include two fermionic real ω-hypermultiplets (Faddeev-Popov ghosts) and one bosonic real ω-hypermultiplet (Nielsen-Kallosh ghost), all in the adjoint representation of the gauge group. The one-loop effective action is analysed in detail and it is found that its structure is determined only by the ghost corrections in the pure super Yang-Mills theory. As applied to the case of N = 4 super Yang-Mills theory, realized in terms of N = 2 superfields, the latter result leads to the remarkable conclusion that the one-loop effective action of the theory does not contain quantum corrections depending on the N = 2 gauge superfield only. We show that the leading low-energy contribution to the one-loop effective action in the N = 2 SU(2) super Yang-Mills theory coincides with Seiberg's perturbative holomorphic effective action. © 1998 Elsevier Science B.V.

description: The soliton structure of a gauge theory recently proposed to describe chiral excitations in the Fractional Quantum Hall Effect is investigated. A new type of non-linear derivative Schrödinger equation emerges as an effective description of the system that supports novel chiral solitons. We discuss the classical properties of solutions with vanishing and non-vanishing boundary conditions (dark solitons) and we explain their relation to integrable systems. The quantum analysis is also addressed in the framework of a semiclassical approximation improved by Renormalization Group arguments.

description: Multi-step temporal difference (TD) learning is an important approach in reinforcement learning, as it unifies one-step TD learning with Monte Carlo methods in a way where intermediate algorithms can outperform either extreme. They address a bias-variance trade off between reliance on current estimates, which could be poor, and incorporating longer sampled reward sequences into the updates. Especially in the off-policy setting, where the agent aims to learn about a policy different from the one generating its behaviour, the variance in the updates can cause learning to diverge as the number of sampled rewards used in the estimates increases. In this paper, we introduce per-decision control variates for multi-step TD algorithms, and compare them to existing methods. Our results show that including the control variates can greatly improve performance on both on and off-policy multi-step temporal difference learning tasks.

description: In spite of making a small contribution to total protoplanetary disk mass, dust affects the disk temperature by controlling absorption of starlight. As grains grow from their initial ISM-like size distribution, settling depletes the disk's upper layers of dust and decreases the optical depth, cooling the interior. Here we investigate the effect of collisional growth of dust grains and their dynamics on the thermal and optical profile of the disk, and explore the possibility that cooling induced by grain growth and settling could lead to gravitational instability. We develop a Monte Carlo dust collision model with a weighting technique and allow particles to collisionally evolve through sticking and fragmentation, along with vertical settling and turbulent mixing. We explore two disk models, the MMEN (minimum-mass extrasolar nebula), and a "heavy" disk with higher surface density than the MMEN, and perform simulations for both constant and spatially variable turbulence efficiency profile $α(R,z)$. We then calculate mean wavelength-dependent opacities for the evolving disks and perform radiative transfer to calculate the temperature profile $T(R,z)$. Finally, we calculate the Toomre Q parameter, a measure of the disk's stability against self-gravity, for each disk model after it reaches a steady state dust-size distribution. We find that even weak turbulence can keep sub-micron sized particles stirred in the disk's upper layer, affecting its optical and thermal profiles, and the growth of large particles in the midplane can make a massive disk optically thick at millimeter wavelengths, making it difficult to calculate the surface density of dust available for planet formation in the inner disk. Also, for an initially massive disk, grain settling and growth can produce a drop in the Toomre Q parameter, driving the disk to $Q < 1.4$ and possibly triggering spiral instabilities.

description: In the regeneration of turbine or compressor blades each blade damage is varying in location, size and shape, depending on the cause of damage. An important regeneration step is the re-contouring which is applied after the deposit welding to remove excess material. With complex blade shapes this step requires 5-axis machining methods. Due to different cases of damage, the re-contouring has to be adapted to each individual repair case to satisfy the high quality requirements regarding the final workpiece. This paper combines the two topics machining strategy and emerging workpiece quality. In this context the work demonstrates a simulation-based approach for the 5-axis re-contouring process. Hence, different 5-axis tool-paths strategies are applied on an analogy repair case including a modelled weld shape. The re-contouring is performed virtually via a dexel based material removal simulation as well as experimentally by using a 5-axis milling machine. Afterwards an evaluation of the different tool-path strategies is done considering achieved workpiece quality. The results imply that the simulation is applicable to predict certain aspects of the workpiece quality such as surface topography. With the simulation system, a tool-path evaluation is possible before re-contouring real workpieces.

description: The robot-assisted manufacturing is introduced for many years in automated production areas, while the production of buildings still follows the traditional manual process. Using new possibilities of digital planning the construction industry demonstrated potential for the implementation of freeform architectures, which are only possible using expensive and only once usable formwork structures. This paper focuses on sprayed concrete technology for automated production processes to build up freeform concrete components. A study case of the production of a concrete wall by an industrial robot, equipped with a concrete spraying tool is presented in order to investigate the possibilities and tolerancing issues of this technique.
First-Order Transition and Critical End-Point in Vortex Liquids in Layered Superconductors

description: We calculate various thermodynamic quantities of vortex liquids in a layered superconductor by using the nonperturbative parquet approximation method, which was previously used to study the effect of thermal fluctuations in two-dimensional vortex systems. We find there is a first-order transition between two vortex liquid phases which differ in the magnitude of their correlation lengths. As the coupling between the layers increases,the first-order transition line ends at a critical point. We discuss the possible relation between this critical end-point and the disappearance of the first-order transition which is observed in experiments on high temperature superconductors at low magnetic fields.

Spatially Ordered Fractional Quantum Hall States
Creators: name: Balents, Leon
Publisher: name: arXiv
Year: 1995
Subjects: subject: Condensed Matter (cond-mat)
subject: FOS: Physical sciences

description: Fractional quantum Hall liquids can accomodate various degrees of spatial ordering. The most likely scenarios are a Hall hexatic, Hall smectic, and Hall crystal, in which respectively orientational, one--dimensional translational, and two--dimensional translational symmetries are broken. I derive the long--wavelength properties of these phases and the transitions between them using the Chern--Simons Landau--Ginzburg mapping, which relates them to spatially ordered superfluids. The effects of coupling to a periodic or anisotropic ``substrate'' (e.g. a gate array) are also discussed.

description: The effect of fluorine on the solubilities of Mn-columbite (MnNb2O6), Mn-tantalite (MnTa2O6), zircon (ZrSiO4) and hafnon (HfSiO4) were determined in highly fluxed, water-saturated haplogranitic melts at 800 to 1000°C and 2kbar. The melt composition corresponds to the intersection of the granite minimum with the albite-orthoclase tieline (Ab72Or28) in the quartz-albite-orthoclase system (Q-Ab-Or), which is representative of a highly fluxed melt, from which high field strength element minerals may crystallize. The melt contains 1.7wt.% P2O5, 1.05wt.% Li2O and 1.83wt.% B2O3. The main purpose of this study is to examine the effect of F on columbite, tantalite, zircon and hafnon solubility for a melt with this composition. Up to 6wt.% fluorine was added as AgF in order to keep the aluminum saturation index (ASI, molar Al/[Na+K]) of the melt constant. In an additional experiment F was added as AlF3 to make a glass peraluminous. The nominal ASI of the melts are close to 1 for the minimum composition and approximately 1.32 in peraluminous glasses, but if Li is considered as an alkali, the molar ratio Al/[Na+K+Li] of the melts are alkaline (0.87) and subaluminous (1.09), respectively. The molar solubility products [MnO]*[Nb2O5] and [MnO]*[Ta2O5] are nearly independent of the F content of the melt, at approximately 18.19±1.2 and 43.65±2.5×10-4 (mol2/kg2), respectively for the minimum composition. By contrast, there is a positive dependence of zircon and hafnon solubilities on the fluorine content in the minimum composition, which increases from 2.03±0.03×10-4 (mol/kg) ZrO2 and 4.04±0.2×10-4 (mol/kg) HfO2 for melts with 0wt.%F to 3.81±0.3×10-4 (mol/kg) ZrO2 and 6.18±0.04×10-4 (mol/kg) HfO2 for melts with 8wt.%F. Comparison of the data from this work and previous studies indicates that ASI of the melt seems to have a stronger effect than the contents of fluxing elements in the melt and the overall conclusion is that fluorine is less important (relative to melt compositions) than previously thought for the control on the behavior of high field strength elements in highly evolved granitic melts. Moreover, this study confirms that although Nb, Ta, Zr and Hf are all high field strength elements, Nb-Ta and Zr-Hf are complexed differently in the melt.
Determination of the QCD color factor ratio CA/CF from the scale dependence of multiplicity in three jet events

Subjects: subject: High Energy Physics - Experiment (hep-ex)

description: I examine the determination of the QCD color factor ratio CA/CF from the scale evolution of particle multiplicity in e+e- three jet events. I fit an analytic expression for the multiplicity in three jet events to event samples generated with QCD multihadronic event generators. I demonstrate that a one parameter fit of CA/CF yields the expected result CA/CF=2.25 in the limit of asymptotically large energies if energy conservation is included in the calculation. In contrast, a two parameter fit of CA/CF and a constant offset to the gluon jet multiplicity, proposed in a recent study, does not yield CA/CF=2.25 in this limit. I apply the one parameter fit method to recently published data of the DELPHI experiment at LEP and determine the effective value of CA/CF from this technique, at the finite energy of the Z0 boson, to be 1.74+-0.03+-0.10, where the first uncertainty is statistical and the second is systematic.

description: It is pointed out that the recent data on strange baryon and antibaryon production in Pb-Pb collisions at 159 GeV/c agree well with the hypothesis of an intermediate state of quasi-free and randomly distributed constituent quarks and antiquarks. Also the S-S data are consistent with this hypothesis. The p-Pb data follow a different pattern.

Conjectured Z_2-Orbifold Constructions of Self-Dual Conformal Field Theories at Central Charge 24 - the Neighborhood Graph

description: By considering constraints on the dimensions of the Lie algebra corresponding to the weight one states of Z_2 and Z_3 orbifold models arising from imposing the appropriate modular properties on the graded characters of the automorphisms on the underlying conformal field theory, we propose a set of constructions of all but one of the 71 self-dual meromorphic bosonic conformal field theories at central charge 24. In the Z_2 case, this leads to an extension of the neighborhood graph of the even self-dual lattices in 24 dimensions to conformal field theories, and we demonstrate that the graph becomes disconnected.

Abstract

This project focuses on the evolutionary engineering of Photosystem II (PS II), a crucial enzyme in photosynthesis that powers all life on Earth by harvesting electrons and protons from water. Despite being one of the slowest evolving enzymes and well-conserved across phyla, PS II is an ever-evolving entity (1).  Directed evolution efforts have been made to explore its evolvability beyond its current arrangement, using an error-prone PCR based in vitro reaction centre subunit D1 library creation platform with D1 deficient Synechocystis sp. PCC 6803 strain. Resultant mutant libraries with variant PS II were tested for atypical light conditions, herbicides, and a possible alternative transition metal cluster by substituting manganese with ruthenium. Several better-performing clones are characterised by biochemical analyses and used as primers for the next round of evolution.

Recent advances in machine learning-based protein structure prediction have also been utilised (AlphaFold 2) to predict the structures of over 700 available D1 sequences spanning cyanobacteria to higher plants, as well as ancestral D1 and D0 (2). These structures were then fed into mTM-align (3) for global and pairwise structural alignments, consensus backbone and distance matrix tree, and residue-level conservation scores were obtained through ConSurf analysis (4). Insights gained from this analysis shed light on the structural divergence of PS II and potential targets for more informed mutagenesis. Comparison with the traditional multiple sequence alignment approach provided further information about known residues versus structural changes. Together, these results provide a promising direction for further exploration of PS II evolvability beyond water oxidation.
