S matrix of collective field theory
Creators: name: Song, Dae-Yup
Publisher: name: arXiv
Year: 1994
Subjects: subject: High Energy Physics - Theory (hep-th)
subject: FOS: Physical sciences

description: By applying the Lehmann-Symanzik-Zimmermann (LSZ) reduction formalism, we study the S matrix of collective field theory in which fermi energy is larger than the height of potential. We consider the spatially symmetric and antisymmetric boundary conditions. The difference is that S matrices are proportional to momenta of external particles in antisymmetric boundary condition, while they are proportional to energies in symmetric boundary condition. To the order of $g_{st}^2$, we find simple formulas for the S matrix of general potential. As an application, we calculate the S matrix of a case which has been conjectured to describe a "naked singularity".

description: Machine learning techniques can reveal hidden structure in large data amounts and can potentially extent or even replace analytical scientific methods. In nanophotonics, modes can increase the light yield from emitters located inside the nanostructure or near the surface. Optimizing such systems enforces to systematically analyze large amounts of three-dimensional field distribution data. We present a method based on finite element simulations and machine learning for the identification of modes with large field energies and specific spatial properties. By clustering we reduce the field distribution data to a minimal subset of prototypes. The predictive power of the approach is demonstrated using an analysis of experimentally measured fluorescence enhancement of quantum dots on a photonic crystal surface. The clustering method can be used for any optimization task that depends on three-dimensional field data, and is therefore relevant for biosensing, quantum dot solar cells or photon upconversion.

description: In the 1950s, a long-term experiment was initiated at three locations in Northern Sweden. The treatments included four cropping systems, which differed in the number of years with leys or annual crops in the crop rotation. To create awareness of the experiment as a research resource for further scientific studies, we summarise the history (experimental design, materials and methods, main measurements) and scientific findings of the experiment, as well as reflect on its usefulness and opportunities for further studies. So far, scientific focus has been on the effects of cropping systems on soil characteristics. The main findings indicate that soil porosity and hydraulic conductivity were greater in cropping systems with a large proportion of ley, soil bulk density showed the opposite trend. In terms of chemical properties, cropping systems incorporating more ley also have greater soil organic carbon content than annual crops systems, and both soil carbon and N storage decrease over time in cropping systems with only annual crops. The effects of cropping system on crop yields and quality are areas for further investigation.

description: We investigate the seven-sphere as a group-like manifold and its extension to a Kac-Moody-like algebra. Covariance properties and tensorial composition of spinors under $S^7$ are defined. The relation to Malcev algebras is established. The consequences for octonionic projective spaces are examined. Current algebras are formulated and their anomalies are derived, and shown to be unique (even regarding numerical coefficients) up to redefinitions of the currents. Nilpotency of the BRST operator is consistent with one particular expression in the class of (field-dependent) anomalies. A Sugawara construction is given.

description: The electronic structure, magnetic properties and phase formation of hexagonal ferromagnetic Fe$_{3}$Sn-based alloys have been studied from first principles and by experiment. The pristine Fe$_{3}$Sn compound is known to fulfill all the requirements for a good permanent magnet, except for the magnetocrystalline anisotropy energy (MAE). The latter is large, but planar, i.e. the easy magnetization axis is not along the hexagonal c direction, whereas a good permanent magnet requires the MAE to be uniaxial. Here we consider Fe$_{3}$Sn$_{0.75}$M$_{0.25}$, where M= Si, P, Ga, Ge, As, Se, In, Sb, Te and Bi, and show how different dopants on the Sn sublattice affect the MAE and can alter it from planar to uniaxial. The stability of the doped Fe$_{3}$Sn phases is elucidated theoretically via the calculations of their formation enthalpies. A micromagnetic model is developed in order to estimate the energy density product (BH)max and coercive field $μ_{0}$H$_{c}$ of a potential magnet made of Fe$_{3}$Sn$_{0.75}$Sb$_{0.25}$, the most promising candidate from theoretical studies. The phase stability and magnetic properties of the Fe$_{3}$Sn compound doped with Sb and Mn has been checked experimentally on the samples synthesised using the reactive crucible melting technique as well as by solid state reaction. The Fe$_{3}$Sn-Sb compound is found to be stable when alloyed with Mn. It is shown that even small structural changes, such as a change of the c/a ratio or volume, that can be induced by, e.g., alloying with Mn, can influence anisotropy and reverse it from planar to uniaxial and back.

Folded Strings

Year: 1994
Subjects: subject: High Energy Physics - Theory (hep-th)
subject: FOS: Physical sciences

description: Recent progress on the complete set of solutions of two dimensional classical string theory in any curved spacetime is reviewed. When the curvature is smooth the string solutions are deformed folded string solutions as compared to flat spacetime folded strings that were known for 19 years. However, surprizing new stringy behavior becomes evident at singularities such as black holes. The global properties of these solutions require that the ``bare singularity region"of the black hole be included along with the usual black hole spacetime. The mathematical structure needed to describe the solutions include a recursion relation that is analogous to the transfer matrix of lattice theories. This encodes lattice properties on the worldsheet on the one hand and the geometry of spacetime on the other hand. A case is made for the presence of folded strings in the quantum theory of non-critical strings for $d\geq 2$.

description: This study used one weekday and one weekend day of dietary recall data for 2,376 school children in NHANES (2003-2008) to address two related objectives: (1) to estimate relationships between school meals participation and weekday dietary intake, controlling for weekend dietary intake as a proxy for food preferences and health beliefs; and (2) to estimate the prevalence of low energy intake and low dietary quality on the weekend, and investigate their associations with household resources and school meals participation. The analysis provided no evidence that a lack of school meals on the weekend adversely affects dietary intake among school children. Low energy intake and low dietary quality were equally prevalent on weekdays and weekend days, and both were unrelated to measures of household resources and school meals participation. We also found that school meals participants and non-participants had equivalent energy intake and overall dietary quality. Low-income children who participated in both SBP and NSLP had significantly higher overall quality, and for grains, meat and beans; while participants from higher income families had significantly lower scores for grains and saturated fat.

description: We study the convex hull of the first $n$ steps of a planar random walk, and present large-$n$ asymptotic results on its perimeter length $L_n$, diameter $D_n$, and shape. In the case where the walk has a non-zero mean drift, we show that $L_n / D_n \to 2$ a.s., and give distributional limit theorems and variance asymptotics for $D_n$, and in the zero-drift case we show that the convex hull is infinitely often arbitrarily well-approximated in shape by any unit-diameter compact convex set containing the origin, and then $\liminf_{n \to \infty} L_n/D_n =2$ and $\limsup_{n \to \infty} L_n /D_n = π$, a.s. Among the tools that we use is a zero-one law for convex hulls of random walks.

description: We report the observation of a giant positive magnetoresistance in millimetre scale hydrogenated graphene with magnetic field oriented in the plane of the graphene sheet. A positive magnetoresistance in excess of 200\% at a temperature of 300 mK was observed in this configuration, reverting to negative magnetoresistance with the magnetic field oriented normal to the graphene plane. We attribute the observed positive, in-plane, magnetoresistance to Pauli-blockade of hopping conduction induced by spin polarization. Our work shows that spin polarization in concert with electron-electron interaction can play a dominant role in magnetotransport within an atomic monolayer.

Several results are obtained that relate the coefficients, $b_i$, in the Shephard-Todd polynomial to the geometry of the fundamental domain. For the 3-sphere we show that $b_4$ is given by the ratio of the volume of the fundamental tetrahedron to its Schläfli reciprocal.

description: This thesis explores a particular class of architectured hybrid materials based on the concept of topological interlocking. In this approach, a structural component is tessellated in identical, discrete elements, which are held in place owing to their specially designed geometry and arrangement. This distinct form of segmentation allows interlocking to occur in three dimensions, providing the structure with an ability to retain its shape, even if some components are fully displaced. In this work, a range of mechanical properties of topologically interlocked assemblies are characterised to provide a greater understanding of the complex deformation mechanisms of these new structures.

description: In this paper, we report a novel redox responsive water-in-oil Pickering emulsion stabilized by negatively charged SiO2 nanoparticles hydrophobized with a trace amount of cationic surfactant 3-pyridyl-5-ferrocenyl-2-pyrazoline (PFP), in which ferrocene serves as a redox-sensitive group. The stability of Pickering emulsion can be modulated by adding oxidant and reducing agent alternatively, which leads to the change of amphiphilicity of SiO2 nanoparticles because of the adsorption of PF+P and desorption of PFP. This destabilization-stabilization behavior can be cycled at least three times, demonstrating that the Pickering emulsion is switchable. At the same time, polyacrylamide@SiO2-PF+P microspheres are prepared using Pickering emulsion as template, which can be used for the detection of Fe3+. Interestingly, when extremely small amounts of microspheres are placed in Fe3+ solution and left overnight, the limit of detection (LOD) decreases significantly because of the synergistic effect of enrichment and fluorescent probe for polyacrylamide and PF+P respectively. Moreover, the fluorescence intensity increased when EDTA was added to the solution containing microspheres and Fe3+, and a decrease of fluorescence intensity was observed when Fe3+ was added again, indicating that the composite microspheres could be reused. This work provides a promising way to construct novel fluorescent probes.

description: The Interface Region Imaging Spectrograph (IRIS) reveals numerous small-scale (sub-arcsecond) brightenings that appear as bright dots sparkling the solar transition region in active regions. Here, we report a statistical study on these transition region bright dots. We use an automatic approach to identify 2742 dots in a Si IV raster image. We find that the average spatial size of the dots is 0.8 arcsec$^2$ and most of them are located in the faculae area. Their Doppler velocities obtained from the Si IV 1394 Å line range from -20 to 20 km/s. Among these 2742 dots, 1224 are predominantly blue-shifted and 1518 are red-shifted. Their nonthermal velocities range from 4 to 50 km/s with an average of 24 km/s. We speculate that the bright dots studied here are small-scale impulsive energetic events that can heat the active region corona.

description: Kazama has described an extension of the N=2 superconformal algebra in which the operator product of G^- with itself is singular. In this paper, we relate actions of this chiral algebra to Drinfeld's theory of Manin pairs, or equivalently, quasi-Lie bialgebras. We also show how to couple topological conformal field theories with this symmetry to topological gravity. As an application, we demonstrate the equivalence of the SL(2)/SL(2) model to a deformed SL(2)/SO(2) model tensored with a free field theory. (Revisions correct some minor errors.)

description: Background: Social connection is a fundamental human need. Its absence can lead to loneliness and social isolation, adversely impacting health and well-being. Given their regular contact and trusted relationships with older people, practitioners delivering community-based primary care are well-positioned to address this issue. However, their contribution to addressing loneliness and social isolation is unclear. Aim: This integrative review explores the contribution of the primary care workforce to interventions aimed at reducing loneliness and social isolation in community-dwelling older people. Method: Using an integrative review method, Scopus, Web of Science, CINAHL and PubMed were searched for original research published between 2000 and 2022. Fourteen papers reporting 13 primary studies were appraised for methodological quality and included in the review. Data were extracted into a summary table and analysed using thematic analysis. Results: Included studies came from over six countries. Internationally, primary care services have diverse structures, funding and workforces influencing their response to loneliness and social isolation. All but one intervention was multi-component, with ten studies including a group-based activity and three providing primarily individual-level activities. Only six studies reported reductions in loneliness following the intervention. Three themes were identified: characteristics of interventions; implementation context, barriers and facilitators; and differing contributions of primary care practitioners in addressing loneliness and social isolation of older people. Conclusion: There is increasing demand and scope for primary care practitioners to assist lonely and socially isolated older people. It is important to understand how to equip and incentivise these practitioners to routinely identify, assess and respond to lonely and socially isolated older people despite varying implementation contexts. There is a need for further research that explores how the primary care team can be better utilised to deliver effective interventions that reduce the health impacts of loneliness and social isolation.

description: The uniqueness of static spherically symmetric traversable wormholes with two asymptotically flat ends, subject to the higher-dimensional solutions of Einstein-Maxwell-phantom dilaton field equations was proved. We considered the case of an arbitrary dilaton coupling constant. Conformal positive energy theorem plays the key role in the considerations.

description: We present an inverse scattering construction of generalised point interactions (GPI) -- point-like objects with non-trivial scattering behaviour. The construction is developed for single centre $S$-wave GPI models with rational $S$-matrices, and starts from an integral transform suggested by the scattering data. The theory of unitary dilations is then applied to construct a unitary mapping between Pontryagin spaces which extend the usual position and momentum Hilbert spaces. The GPI Hamiltonian is defined as a multiplication operator on the momentum Pontryagin space and its free parameters are fixed by a physical locality requirement. We determine the spectral properties and domain of the Hamiltonian in general, and construct the resolvent and Møller wave operators thus verifying that the Hamiltonian exhibits the required scattering behaviour. The physical Hilbert space is identified. The construction is illustrated by GPI models representing the effective range approximation. For negative effective range we recover a known class of GPI models, whilst the positive effective range models appear to be new. We discuss the interpretation of these models, along with possible extensions to our construction.

description: With its vote of 28 February 2024, the European Parliament supported the EU Commission's proposal (COM(2023)0232) for a regulation on standard essential patents (SEPs)). Despite the stark criticism of the draft Regulation – particularly from the SEP holders – the European Parliament is not proposing any fundamental changes. The draft Regulation is now under review by the Council of the European Union. Once the Council presents its position, with potentially further requests for changes to the draft, the interinstitutional negotiations between the EU Commission, Council and EU Parliament ("trialogue") will follow.

This newly proposed regulation aims to streamline SEP licensing by enhancing transparency, reducing information asymmetries between SEP holders and implementers, and facilitating agreements on fair, reasonable, and non-discriminatory (FRAND) licenses. A notable feature of the proposal is the establishment of a competence center at the EU Intellectual Property Office (EUIPO), which will manage a registry and database for SEPs. SEP holders will be required to register their SEPs, which will undergo essentiality checks. The setting of an aggregate royalty and conciliation will also be offered by the EUIPO.

While the initiative has received broad support from stakeholders and academics for its potential to increase transparency, it faces opposition from major SEP holders and other interested parties. The webinar explores these developments, discusses their implications, and answers your questions about how these regulatory changes might impact your business and the broader technology ecosystem.

RG flow in 2d field theory coupled to gravity

Year: 1994
Subjects: subject: High Energy Physics - Theory (hep-th)
subject: FOS: Physical sciences

description: The renormalization group flow in two--dimensional field theories is modified if they are coupled to gravity. Beta function coefficients are changed, the $c$--theorem is no longer strictly valid, and flows from fixed points with central charge $c>25$ to fixed points with $c<25$ are forbidden. This is discussed in general and at two examples, the Kosterlitz--Thouless phase transition and the Wess--Zumino--Witten model. A possible application to string cosmology is pointed out.

description: Introduction: The health benefits of prophylactic dosing regimens for clotting factor therapy in patients with hemophilia include reduced joint damage and improved quality of life; as such, prophylaxis is recommended in treatment guidelines. However, many patients with hemophilia B are treated on demand, and prophylaxis has been utilized less frequently than in hemophilia A. Areas covered: This review discusses the opportunities and evidence for prophylaxis in hemophilia B, in the context of treatment guidelines and with regard to factor IX (FIX) replacement therapies, including long-acting recombinant FIX (rFIX). Expert commentary: Long-acting rFIX concentrates may increase uptake of and adherence to prophylaxis regimens through attainment of higher trough levels with longer dosing intervals. In this new era of hemophilia B treatment, physicians may be able to achieve better clinical outcomes for their patients and reconsider treatment goals. Maintaining higher FIX trough levels will undoubtedly have long-term benefits for patients, such as preserving joint function. The long-acting rFIX concentrates support robust prophylaxis regimens and offer physician’s flexibility in treating patients to best suit their needs, whether to enable an active lifestyle, to achieve higher trough levels for better bleed protection, or simply to decrease the burden of treatment by reducing injection frequency.

description: We adapt the friends of friends algorithm to the analysis of light curves, and show that it can be successfully applied to searches for transient phenomena in large photometric databases. As a test case we search OGLE-III light curves for known dwarf novae. A single combination of control parameters allows to narrow the search to 1% of the data while reaching a $\sim$90% detection efficiency. A search involving $\sim$2% of the data and three combinations of control parameters can be significantly more effective - in our case a 100% efficiency is reached. The method can also quite efficiently detect semi-regular or strictly periodic variability. We report 28 new variables found in the field of the globular cluster M22, which was examined earlier with the help of periodicity-searching algorithms

On Diff(S^1) Covariantization Of Pseudodifferential Operator

description: A study of diff($S^1$) covariant properties of pseudodifferential operator of integer degree is presented. First, it is shown that the action of diff($S^1$) defines a hamiltonian flow defined by the second Gelfand-Dickey bracket if and only if the pseudodifferential operator transforms covariantly. Secondly, the covariant form of a pseudodifferential operator of degree n not equal to 0, 1, -1 is constructed by exploiting the inverse of covariant derivative. This, in particular, implies the existence of primary basis for W_{KP}^{(n)} (n not equal to 0, 1, -1).

Bayesian Inference on the Radio-quietness of Gamma-ray Pulsars

description: We demonstrate for the first time using a robust Bayesian approach to analyse the populations of radio-quiet (RQ) and radio-loud (RL) gamma-ray pulsars. We quantify their differences and obtain their distributions of the radio-cone opening half-angle $δ$ and the magnetic inclination angle $α$ by Bayesian inference. In contrast to the conventional frequentist point estimations that might be non-representative when the distribution is highly skewed or multi-modal, which is often the case when data points are scarce, Bayesian statistics displays the complete posterior distribution that the uncertainties can be readily obtained regardless of the skewness and modality. We found that the spin period, the magnetic field strength at the light cylinder, the spin-down power, the gamma-ray-to-X-ray flux ratio, and the spectral curvature significance of the two groups of pulsars exhibit significant differences at the 99\% level. Using Bayesian inference, we are able to infer the values and uncertainties of $δ$ and $α$ from the distribution of RQ and RL pulsars. We found that $δ$ is between $10^\circ$ and $35^\circ$ and the distribution of $α$ is skewed towards large values.

description: This project involved the execution of data sharing agreements and preparation of a publically accessible database and summary reports for the National Food and Nutrition Study (NATFAN). NATFAN used repeated cross-sectional surveys conducted in WIC clinics between 2009 and 2011, before and after the changes in the WIC food benefit, to examine dietary practices. Women who attended WIC clinics during the periods of the two surveys completed questionnaires about their own (Women questionnaire), their child’s (Child questionnaire), or their infant’s (Infant questionnaire) consumption of certain foods related to the changes in the WIC food package. Reports on food consumption for milk, grains, fruits and vegetables, beverages, and baby foods include data from the 39 State WIC Programs and consolidated data from 10 Indian Tribal Organization WIC Programs before and after the WIC changes. The data dictionary and code book and the public dataset include data from all participating WIC programs.

Quantization of the Lie Algebra SO(2N+1) and of the Lie Superalgebra Osp(1/2N) with Preoscillator Generators
Creators: name: Palev, Tchavdar D.

Year: 1994
Subjects: subject: High Energy Physics - Theory (hep-th)

description: The Lie algebra $so(2n+1)$ and the Lie superalgebra $osp(1/2n)$ are quantized in terms of $3n$ generators, called preoscillator generators. Apart from $n$ "Cartan" elements the preoscillator generators are deformed para-Fermi operators in the case of $so(2n+1)$ and deformed para-Bose operators in the case of $osp(1/2n)$. The corresponding deformed universal enveloping algebras $U_q[so(2n+1)]$ and $U_q[osp(1/2n)]$ are the same as those defined in terms of Chevalley operators. The name "preoscillator" is to indicate that in a certain representation these operators reduce to the known deformed Fermi and Bose operators.
