Nuclear alpha-particle condensates: Definitions, occurrence conditions, and consequences

description: There has been a recent flurry of interest in the possibility of condensates of $α$-particles in nuclei. In this letter we discuss occurrence conditions for such states. Using the quantality condition of Mottelson we show that condensates are only marginally expected in $α$-particle states. We proceed to demonstrate that few-body nuclear condensates are ill-defined, and emphasize the conflict between $α$-localization and $α$-condensate formation. We also explore the connection between Ikeda diagrams, linear chains, and Tonks-Girardeau gases. Our findings show that no new information is contained in the approximations of nuclear states as $α$-cluster condensates. Furthermore, condensates of more than three $α$-particles are very unlikely to exist due to couplings to other degrees of freedom.

Improving Multigrid and Conventional Relaxation Algorithms for Propagators
Creators: name: Kalkreuter, Thomas
Publisher: name: arXiv
Year: 1992
Subjects: subject: High Energy Physics - Lattice (hep-lat)
subject: FOS: Physical sciences

description: Practical modifications of deterministic multigrid and conventional relaxation algorithms are discussed. New parameters need not be tuned but are determined by the algorithms themselves. One modification can be thought of as ``updating on a last layer consisting of a single site''. It eliminates critical slowing down in computations of bosonic and fermionic propagators in a fixed volume. Here critical slowing down means divergence of asymptotic relaxation times as the propagators approach criticality. A remaining volume dependence is weak enough in case of bosons so that conjugate gradient can be outperformed. However, no answer can be given yet if the same is true for staggered fermions on lattices of realizable sizes. Numerical results are presented for propagators of bosons and of staggered fermions in 4-dimensional $SU(2)$ gauge fields.

The Demand for Intercity Passenger Transportation

Publisher: name: Carnegie Mellon University

Subjects: subject: 150399 Business and Management not elsewhere classified
subject: FOS: Economics and business

description: Transportation demand models tend to be fragile and limited. They are developed for specific purposes and are unreliable when used more generally. In particular, past models have been deficient in not explaining passenger demand in terms of the attributes of the modes. This means that there is no way to forecast the effect of changes such as increased speed or safety on passenger demand. Furthermore, these models are invariably mode specific and consequently provide no way of looking at total travel when one mode is changed significantly or a new mode introduced. Some recent attempts have been made to develop more general models (Quandt [9]). While these attempts are salutary, much work remains to be done.

description: We discuss a deformation of the Hopf algebra of supersymmetry (SUSY) transformations based on a special choice of twist. As usual, algebra itself remains unchanged, but the comultiplication changes. This leads to the deformed Leibniz rule for SUSY transformations. Superfields are elements of the algebra of functions of the usual supercoordinates. Elements of this algebra are multiplied by using a $\star$-product which is noncommutative, hermitian and finite when expanded in power series of the deformation parameter. Chiral fields are no longer a subalgebra of the algebra of superfields. One possible deformation of the Wess-Zumino action is proposed and analysed in detail. Differently from most of the literature concerning this subject, we work in Minkowski space-time.

description: Gravitational Compton scattering process with a massive fermion is studied in the context of the linearized gravity. Gravitational gauge invariance and graviton transversality cause the transition amplitude to be factorized into that of scalar QED Compton scattering and that of fermion QED Compton scattering with an overall kinematical factor. The factorization is shown explicitly and its physical implications are discussed.

description: The rapid increase in scientific literature has necessitated finding more efficient ways to locate the studies of relevance. For example, the number of biomedical journals increased from five in 1799 to more than twenty-three thousand in 1977 (McCarn, forthcoming). For the biomedical literature, the first large-scale attempt to search bibliographic references using a computer was the MEDLARS system of the National Library of Medicine (see McCarn and Leiter, 1973 for a description). As originally set up, the system was designed for batch processing; the user communicated by mail, and a search request typically took several weeks to process.

description: The history of AI and robotics is sometimes traced back to Ancient Greece, where automata were used in temples and theatres. Arguably, ancient automata carried seemingly very different cultural meanings than the technology of today. However, classics scholars highlight the political functions of ancient automata that were based on their ability to evoke awe in the spectators. The concept of θαῦμα ἰδέσθαι (thauma idesthai) portrays the impact of the miraculous, designed and perpetuated in order to support the power of the ruling elite. Most interestingly, temple automata were displayed and recognised as obvious masterpieces of human engineering, while the cultural-religious context enabled the interpretation of exceptional skill as the manifestation of divine support, signifying the worthiness of the rulers. I argue that the politics around contemporary AI function to an extent in a similar manner.

The Deficit: A Monetarist's Perspective

Subjects: subject: 150399 Business and Management not elsewhere classified
subject: FOS: Economics and business

description: There is no "monetarist position" on the budget deficit. Monetarism is mainly about the effects of money on inflation. Deficits have an effect on inflation—defined as the maintained rate of price change—only if they are financed by issuing money. Argentina, Bolivia, and Brazil are recent examples of inflations financed by money issued to pay for government spending. In these or other countries with budget deficits equal to 15 per cent of GNP or more, people observe that the government is unwilling to raise taxes or reduce spending; they expect inflation, so they resist holding domestic money. There is a flight from money, rapid money growth, and rising inflation. When the budget deficit was reduced Argentina and Bolivia were able to reduce money growth and inflation.

title: Interannual Variation of Stratification in Lower Chesapeake Bay
Creators: name: Katzenmiller, Christopher S.
Publisher: name: Old Dominion University
publisherIdentifier: https://ror.org/04zjtrb98

Year: 2005

description: Stratification in the water column can prove to be an important indicator to the state of the water column and ecosystem. The focus of this research is to evaluate trends in stratification in the Lower Chesapeake Bay. Detailed analysis was performed on a 14 year data set to study interannual variation in the region of study. Potential energy anomaly was used to quantify stratification. Potential energy anomaly is the amount of energy required to mix a water column. It is determined from the vertical density structure of density. Potential energy anomaly is the departure of potential energy from climate conditions. The research did find trends in the periodicity of the potential energy anomaly. Three stations are described in detail through this paper but 14 stations were evaluated by the methods in the paper. The work indicated an annual frequency through frequency analysis of the data. A secondary signal was one of approximately 3 years. An indicative station from the research was Station 6.3C that displayed periods of one year and three years from the analysis. The results could be further analyzed and explained in the future by increasing the number of stations in the northern part of the Bay and using more up to date data.

description: Synchronization is a ubiquitous phenomenon in nature and we propose its new perspective in ultrafast dynamics in interacting electron systems. In particular, using graphene irradiated by an intense bi-circular pulse laser as a prototypical and experimental viable example, we theoretically investigate how to selectively generate a coherent oscillation of electronic order such as charge density waves (CDW). The key is to use tailored fields that match the crystalline symmetry broken by the target order. After the pump, a macroscopic number of electrons start oscillating and coherence is built up through a transition. The resulting physics is detectable as a coherent light emission at the synchronization frequency and may be used as a purely electronic way of realizing Floquet states respecting exotic space time crystalline symmetries. In the process, we also explore possible flipping of existing static CDW orders and generation of higher harmonics. The general framework for the coherent electronic order is found to be analogous with the celebrated Kuramoto model, describing the classical synchronization of coupled pendulums.

description: We show that equity returns, the term spread, and excess returns on a broad range of assets are positively correlated with future economic growth. The common tendency for excess returns to lead the business cycle suggests a macroeconomic factor in the cyclical behavior of asset returns. We construct an exchange economy that illustrates how this might work. Its important ingredients are recursive preferences, stochastic volatility in consumption growth, and dynamic interaction between volatility and growth.

Developing Formal Representations of Building Regulations through a Parallel Drafting Process

Publisher: name: Apollo - University of Cambridge Repository
Year: 2024

description: Interpreting and computerising building regulations is crucial for automated compliance checking of buildings, enabling a faster and more objective building permit review. Since natural language regulations are often not designed to be represented formally, integrating formal representations into the regulation drafting process could significantly enhance computability. Through in-depth qualitative expert interviews with regulators worldwide, this study delves into the drafting process of building regulations. It aims to establish a methodology for developing formal representations in parallel with natural language versions. To be able to do so, the first step is to understand the current workflow and its requirements. The interviewees noted several benefits from parallel drafting, such as improved regulation quality and reduced inconsistencies, but acknowledged the difficulties in modifying existing laws and the considerable time and costs associated with these changes. Based on these findings, different parallel drafting strategies have been explored, with ongoing research aimed at specifying a more robust foundation.

The null cusp string solution and its closed spinning string counterpart are related to the sinh-Gordon vacuum. We construct classical string solutions corresponding to sinh-Gordon solitons, antisolitons and breathers by the inverse scattering technique. The breather solutions can also be reproduced by the sigma model dressing method.

Fermion Interactions in the Wilson Yukawa Approach for Lattice Chiral Gauge Theories

description: We consider fermion-gauge couplings in the Wilson-Yukawa approach for lattice chiral gauge theories. At the leading order of a fermionic hopping parameter expansion we find that the fermion-gauge coupling has a chiral and tree-like structure. We argue that this fermion-gauge coupling remains non-zero in the continuum limit taken in the Higgs phase. Possible fermion-scalar couplings in this approach are considered. We also evaluate the fermion interaction with an external gauge field in the slightly modified model and show that it has a chiral structure in general.

description: Together with the existence of new neutral gauge bosons, models based on extended gauge groups (rank $> 4$) often predict also new charged fermions. A mixing of the known fermions with new states with {\it exotic} weak-isospin assignments (left-handed singlets and right-handed doublets) will induce tree level flavour changing neutral interactions mediated by $Z$ exchange, while if the mixing is only with new states with {\it ordinary} weak-isospin assignments, the flavour changing neutral currents are mainly due to the exchange of the lightest new neutral gauge boson $Z^\prime$. We show that the present experimental limits on $μ-e$ conversion in nuclei give a nuclear-model-independent bound on the $Z$-$e$-$μ$ vertex which is twice as strong as that obtained from $μ\to e e e$. In the case of E$_6$ models these limits provide quite stringent constraints on the $Z^\prime$ mass and on the $Z-Z^\prime$ mixing angle. We point out that the proposed experiments to search for $μ-e$ conversion in nuclei have good chances to find evidence of lepton flavour violation, either in the case that new exotic fermions are present at the electroweak scale, or if a new neutral gauge boson $Z^\prime$ of E$_6$ origin lighter than a few TeV exists.

description: By numerical simulations in {\it real time} we provide evidence in favour of sphaleron like transitions in the hot, symmetric phase of the electroweak theory. Earlier performed observations of a change in the Chern-Simons number are supplemented with a measurement of the lowest eigenvalues of the three-dimensional staggered fermion Dirac operator and observations of the spatial extension of energy lumps associated with the transition. The observations corroborate on the interpretation of the change in Chern-Simons numbers as representing continuum physics, not lattice artifacts. By combining the various observations it is possible to follow in considerable detail the time-history of thermal fluctuations of the classical gauge-field configurations responsible for the change in the Chern-Simons number.

description: This talk is based on the work Donevski et al. , to be submitted - we aim to tackle one of existing challenges in dusty, galaxy formation and evolution by estimating the evolution of \(M_{\rm dust}/M_{\star}\)over cosmic time. I explain how to take particular care of understanding the eventual systematics of estimated physical properties. I show how we model and interpret our results in the context of galaxy formation and evolution by confronting the findings to the newest generation of galaxy models and simulations that include self-consistent dust growth. We find that the ratio between dust and stellar mass can be used as a great diagnostics to disentangle MS and SB galaxies over all redshifts.

description: In 1962, Overhauser showed that within Hartree-Fock (HF) the electron gas is unstable to a spin density wave (SDW) instability. Determining the true HF ground state has remained a challenge. Using numerical calculations for finite systems and analytic techniques, we study the HF ground state of the 3D electron gas. At high density, we find broken spin symmetry states with a nearly constant charge density. Unlike previously discussed spin wave states, the observed wave vector of the SDW is smaller than $2 k_F$. The broken-symmetry state originates from pairing instabilities at the Fermi surface, a model for which is proposed.

description: To address the sparsity and cold start problem of collaborative filtering, researchers usually make use of side information, such as social networks or item attributes, to improve recommendation performance. This paper considers the knowledge graph as the source of side information. To address the limitations of existing embedding-based and path-based methods for knowledge-graph-aware recommendation, we propose Ripple Network, an end-to-end framework that naturally incorporates the knowledge graph into recommender systems. Similar to actual ripples propagating on the surface of water, Ripple Network stimulates the propagation of user preferences over the set of knowledge entities by automatically and iteratively extending a user's potential interests along links in the knowledge graph. The multiple "ripples" activated by a user's historically clicked items are thus superposed to form the preference distribution of the user with respect to a candidate item, which could be used for predicting the final clicking probability. Through extensive experiments on real-world datasets, we demonstrate that Ripple Network achieves substantial gains in a variety of scenarios, including movie, book and news recommendation, over several state-of-the-art baselines.

description: Atomically thin graphene exhibits fascinating mechanical properties, although its hardness and transverse stiffness are inferior to those of diamond. To date, there hasn't been any practical demonstration of the transformation of multi-layer graphene into diamond-like ultra-hard structures. Here we show that at room temperature and after nano-indentation, two-layer graphene on SiC(0001) exhibits a transverse stiffness and hardness comparable to diamond, resisting to perforation with a diamond indenter, and showing a reversible drop in electrical conductivity upon indentation. Density functional theory calculations suggest that upon compression, the two-layer graphene film transforms into a diamond-like film, producing both elastic deformations and sp2-to-sp3 chemical changes. Experiments and calculations show that this reversible phase change is not observed for a single buffer layer on SiC or graphene films thicker than 3 to 5 layers. Indeed, calculations show that whereas in two-layer graphene layer-stacking configuration controls the conformation of the diamond-like film, in a multilayer film it hinders the phase transformation.

description: Large surveys have been performed from the ultraviolet (UV) to the far-infrared (FIR). Some galaxies are observed over this whole wavelength range, and through SED fitting we get accurate estimates of their stellar and dust properties. Unfortunately, most galaxies are only detected at a limited part of this spectrum. With machine learning techniques, we can use the UV-FIR galaxies as a blueprint: we learn the mapping from their fluxes to their properties. For example, a mapping from UV-NIR to dust mass can be established, and then applied to galaxies that lack FIR data. We present this approach using DustPedia and H-ATLAS data, and show the superiority over energy balance SED fitting. Besides what can be directly estimated from the SEDs alone, this technique implicitly uses relations that follow from galaxy evolution. To avoid a black box, we take special care to estimate uncertainties on our predictions and to interpret the model.

The Importance of Temporal Integration in DCE-MRI for Improved Breast Cancer Diagnosis
Creators: name: Ceccarelli, Francesco
name: Holden, Sean
Publisher: name: Apollo - University of Cambridge Repository
Year: 2025

description: Dynamic Contrast-Enhanced Magnetic Resonance Imaging (DCE-MRI) is a sequence of MRI scans acquired after the administration of a contrast agent. In Breast cancer, it is used to capture dynamic changes in tissue enhancement over time, which is shown to be different between benign and malignant lesions. In fact, the DCE-MRI is a temporal sequence of MRI composted of one pre-contrast and six post-contrast instant. This study leverages machine learning techniques to enhance breast cancer classification using the full sequence of DCE-MRI data, addressing the common oversight of underutilizing its temporal dimension. We analyze an in-house dataset, integrating radiomic features from each time instant through \textit{i)} feature concatenated from all instants of the sequence and a random forest model (multi-instant Random Forest), and \textit{ii)} a graph neural network (GNN) to extract informative embeddings in which nodes correspond to the seven time instants of the DCE-MRI sequence. Our findings indicate that incorporating temporal information significantly improves classification performance, both in terms of accuracy and particularly in terms of Positive Predictive Value (PPV), which is crucial for reducing false positives in clinical decisions. Despite the complexity of GNNs, their performance gains are marginal compared to the simpler multi-instant RF, suggesting that shallower models may be equally effective with smaller datasets. Explainable AI methods further reveal that the pre-contrast and third post-contrast instants are most informative for classification, offering new insights for radiology physicians.

description: The 3rd Quarter GNP figures when examined carefully are not as depressing as many people think. The main depressing influence was the very sharp reduction in inventories relative to sales, particularly inventories of durables. Final sales (GNP-inventory change) rose 7.9% against 8% in the 2nd quarter. After adjustment for price change, the 3rd Quarter rise in sales is larger than the 2nd Quarter increase.

description: The polymer (PBDTTT-c) p-doped with the molecular dopant (Mo(tfd-COCF3)3) exhibits a decline in transport properties at high doping concentrations, which limits the performance attainable through organic semiconductor doping. Scanning Electron Microscopy is used to correlate the evolution of hole conductivity and hopping transport activation energy with the formation of aggregates in the layer. Transmission Electron Microscopy with energy-dispersive X-ray analysis along with liquid-state Nuclear Magnetic Resonance experiments are carried out to determine the composition of the aggregates. This study offers an explanation to the limited efficiency of doping at high dopant concentrations and reinforces the need to increase doping efficiency in order to be able to reduce the dopant concentration and not negatively affect conductivity.

description: An exploratory numerical study of the influence of heavy fermion doublets on the mass of the Higgs boson is performed in the decoupling limit of a chiral $\rm SU(2)_L \otimes SU(2)_R$ symmetric Yukawa model with mirror fermions. The behaviour of fermion and boson masses is investigated at infinite bare quartic coupling on $4^3 \cdot 8$, $6^3 \cdot 12$ and $8^3 \cdot 16$ lattices. A first estimate of the upper bound on the renormalized quartic coupling as a function of the renormalized Yukawa-coupling is given.

description: Knowledge of the importance of input features towards decisions made by machine-learning models is essential to increase our understanding of both the models and the underlying data. Here, we present a new approach to estimating feature importance with neural networks based on the idea of distributing the features of interest among experts in an attentive mixture of experts (AME). AMEs use attentive gating networks trained with a Granger-causal objective to learn to jointly produce accurate predictions as well as estimates of feature importance in a single model. Our experiments show (i) that the feature importance estimates provided by AMEs compare favourably to those provided by state-of-the-art methods, (ii) that AMEs are significantly faster at estimating feature importance than existing methods, and (iii) that the associations discovered by AMEs are consistent with those reported by domain experts.

description: Supplementary files for article "Associations between parent and child latent eating profiles and the role of parental feeding practices"Previous research employing the person-centred approach of Latent Profile Analysis (LPA) with parent-reported data of their child's eating behaviour identified four distinct eating profiles in 3-6-year-old children: typical, avid, happy, and avoidant eating (Pickard et al., 2023). In this follow-up study, the same parents were asked to self-report their own eating behaviour (N = 785) and LPA was conducted to determine the latent eating profiles of the parents/caregivers. The LPA showed that a four-profile solution best represented the sample of parents, termed: typical eating (n = 325, 41.4%), avid eating (n = 293, 37.3%), emotional eating (n = 123, 15.7%) and avoidant eating (n = 44, 5.6%). Multiple mediation analysis was then conducted to examine both the direct associations between parents' eating profiles and the child's probability of eating profile membership, as well as the indirect associations through the mediatory role of specific parental feeding practices. The results suggested direct links between parent and child eating profiles, with the 'avid eating' and 'avoidant eating' profiles in parents predicting similar profiles in their children. Feeding practices, such as using food for emotional regulation, providing balanced and varied food, and promoting a healthy home food environment, mediated associations between parent and child eating profiles. This research provides novel evidence to reinforce the need for interventions to be specifically tailored to both the parent's and child's eating profiles. The work also provides an interesting avenue for future longitudinal examination of whether the parents' provision of a healthy home food environment could protect against intergenerational transmission of less favourable eating behaviours.© The Author(s), CC BY 4.0
Parton correlation functions and factorization in deep inelastic scattering

description: We outline the basic properties of a pertubative QCD factorization formalism that maintains exact over-all kinematics in both the initial and final states. Such a treatment requires the use of non-perturbative factors that depend on all components of parton four-momentum. These objects are referred to as parton correlation functions. We describe the complications faced in defining parton correlation functions and discuss recent progress. Emphasis is placed on the need for precise operator definitions in a complete derivation of factorization.

description: From 1947 to 1964 the United States maintained a relatively stable monetary framework under which many countries recovered, developed, and prospered. Inflation remained low in the United States and in other nations that tied the values of their currencies—their exchange rates—to the dollar. The framework and the procedures were not ideal, but they produced greater stability than the monetary systems that preceded or followed.

description: In this paper, we address a class of problems in unitary ensembles. Specifically, we study the probability that a gap symmetric about 0, i.e. $(-a,a)$ is found in the Gaussian unitary ensembles (GUE) and the Jacobi unitary ensembles (JUE) (where in the JUE, we take the parameters $α=β$). By exploiting the even parity of the weight, a doubling of the interval to $(a^2,\infty)$ for the GUE, and $(a^2,1)$, for the (symmetric) JUE, shows that the gap probabilities maybe determined as the product of the smallest eigenvalue distributions of the LUE with parameter $α=-1/2,$ and $α=1/2$ and the (shifted) JUE with weights $x^{1/2}(1-x)^β$ and $x^{-1/2}(1-x)^β$ The $σ$ function, namely, the derivative of the log of the smallest eigenvalue distributions of the finite-$n$ LUE or the JUE, satisfies the Jimbo-Miwa-Okamoto $σ$ form of $P_{V}$ and $P_{VI}$, although in the shift Jacobi case, with the weight $x^α(1-x)^β,$ the $β$ parameter does not show up in the equation. We also obtain the asymptotic expansions for the smallest eigenvalue distributions of the Laguerre unitary and Jacobi unitary ensembles after appropriate double scalings, and obtained the constants in the asymptotic expansion of the gap probablities, expressed in term of the Barnes $G-$ function valuated at special point.

description: Automatic transcriptions of consumer-generated multi-media content such as "Youtube" videos still exhibit high word error rates. Such data typically occupies a very broad domain, has been recorded in challenging conditions, with cheap hardware and a focus on the visual modality, and may have been post-processed or edited. In this paper, we extend our earlier work on adapting the acoustic model of a DNN-based speech recognition system to an RNN language model and show how both can be adapted to the objects and scenes that can be automatically detected in the video. We are working on a corpus of "how-to" videos from the web, and the idea is that an object that can be seen ("car"), or a scene that is being detected ("kitchen") can be used to condition both models on the "context" of the recording, thereby reducing perplexity and improving transcription. We achieve good improvements in both cases and compare and analyze the respective reductions in word error rate. We expect that our results can be used for any type of speech processing in which "context" information is available, for example in robotics, man-machine interaction, or when indexing large audio-visual archives, and should ultimately help to bring together the "video-to-text" and "speech-to-text" communities.
