description: We present the deformed (for the presence of Calogero potential terms) one-dimensional quantum oscillator with the exceptional Lie superalgebra $F(4)$ as spectrum-generating superconformal algebra. The Hilbert space is given by a $16$-ple of square-integrable functions. The energy levels are $\frac{2}{3}+n$, with $n=0,1,2,\ldots$. The ground state is $7$ times degenerate. The excited states are $8$ times degenerate. The $(7,8,8,8,\ldots )$ semi-infinite tower of states is recovered from the $(7;8;1)$ supermultiplet of the ${\cal N}=8$ worldline supersymmetry. The model is unique, up to similarity transformations, and admits an octonionic-covariant formulation which manifests itself as "quasi-nonassociativity". This means, in particular, that the Calogero coupling constants are expressed in terms of the octonionic structure constants. The associated $F(4)$ superconformal quantum mechanics is also presented.

description: We show that a double quantum-dot system made of diluted magnetic semiconductor behaves unlike usual molecules. In a semiconductor double quantum dot or in a diatomic molecule, the ground state of a single carrier is described by a symmetric orbital. In a magnetic material molecule, new ground states with broken symmetry can appear due the competition between the tunnelling and magnetic polaron energy. With decreasing temperature, the ground state changes from the normal symmetric state to a state with spontaneously broken symmetry. Interestingly, the symmetry of a magnetic molecule is recovered at very low temperatures. A magnetic double quantum dot with broken-symmetry phases can be used a voltage-controlled nanoscale memory cell.

description: We have established a novel route for the synthesis of N-doped TiO2 by adopting flame aerosol (FSP) technique and investigated the effect of water content on the physico-chemical properties of the as-synthesized nanoparticles. The key characteristics of the developed method are to modify the precursor solution in order to incorporate nitrogen atoms into the TiO2 lattice without altering the FSP set-up. The reduction of the flame enthalpy resulting in N-incorporation into the TiO2 and the N-doping can be greatly enhanced further by the addition of secondary N-source (urea). Our XRD results reveal a shift of the (101) plane anatase diffraction peak to lower angles in our N-doped TiO2 compared to undoped TiO2 which suggest the distortion and strain in the crystal lattice prompted by the incorporation of the nitrogen atoms. The growth or expansion of crystal lattice can be attributed to the larger atomic radius of respective nitrogen atoms (r = 1.71 Å) compared to oxygen (r = 1.40 Å). Our XPS and EDX spectroscopy results elucidate that the nitrogen was effectively doped into the crystal lattice of TiO2 in our as-synthesized N-TiO2 catalysts predominantly in the form of interstitial nitrogen (Ti−O−N). The nitrogen atoms incorporation into the crystal lattice of titania modifies the electronic band structure of TiO2, resulting in a new mid-gap energy state N 2p band formed above O 2p valance band. This occurrence narrows the band gap of TiO2 (from 3.12 to ∼2.51 eV) in our N-doped TiO2 and shifts the optical absorption to the visible region.

description: Bag manipulation through robots is complex and challenging due to the deformability of the bag. Based on dynamic manipulation strategy, we propose a new framework, ShakingBot, for the bagging tasks. ShakingBot utilizes a perception module to identify the key region of the plastic bag from arbitrary initial configurations. According to the segmentation, ShakingBot iteratively executes a novel set of actions, including Bag Adjustment, Dual-arm Shaking, and One-arm Holding, to open the bag. The dynamic action, Dual-arm Shaking, can effectively open the bag without the need to account for the crumpled configuration.Then, we insert the items and lift the bag for transport. We perform our method on a dual-arm robot and achieve a success rate of 21/33 for inserting at least one item across various initial bag configurations. In this work, we demonstrate the performance of dynamic shaking actions compared to the quasi-static manipulation in the bagging task. We also show that our method generalizes to variations despite the bag's size, pattern, and color.

description: The efficiency of evaporative cooling, which is used for the creation of a Bose Einstein condensate, depends strongly on the number of particles at the start of the evaporation. A high efficiency can be reached by filling the magneto-optical trap with a large number of atoms and subsequently transferring these atoms to the magnetic trap as efficiently as possible. In our case (for sodium) this efficiency is limited to 1/3, because the magnetic substates of the F = 1 state, which is used in the trapping process, are equally populated. This limit can be overcome by spin-polarizing the sample before the transfer. For sodium atoms, however, the improvement is very small when it is done in a small magnetic field due to the large number of optical transitions in combination with the high optical density. In this article we describe spin-polarizing sodium atoms in a high magnetic field. The transfer efficiency is increased by a factor of 2. The high magnetic field makes the process also more robust against variations in the magnetic field, the laser frequency and the polarization of the laser beam.

description: A quantum $n$-particle model consisting of an open $q$-difference Toda chain with two-sided boundary interactions is placed on a finite integer lattice. The spectrum and eigenbasis are computed by establishing the equivalence with a previously studied $q$-boson model from which the quantum integrability is inherited. Specifically, the $q$-boson-Toda correspondence in question yields Bethe Ansatz eigenfunctions in terms of hyperoctahedral Hall-Littlewood polynomials and provides the pertinent solutions of the Bethe Ansatz equations via the global minima of corresponding Yang-Yang type Morse functions.

On the Probability Distribution of Velocity Circulation in Three-Dimensional Turbulence

description: The probability distribution functions of the circulation of velocity in three-dimensional decaying isotropic turbulence are examined by the database of the numerical simulation based on the pseudospectral method. It is shown that the standard deviation increases nearly as $A^{2/3}$ where $A$ is the area of the loop. The PDFs change from exponential to gaussian as the size becomes large. The former agrees well with the prediction by Migdal (1993), although the latter does not match. A modification is proposed to explain the gaussian distribution with the $A^{2/3}$ dependence.

Predicting tensorial electrophoretic effects in asymmetric colloids

Year: 2017
Subjects: subject: Soft Condensed Matter (cond-mat.soft)
subject: FOS: Physical sciences

description: We formulate a numerical method for predicting the tensorial linear response of a rigid, asymmetrically charged body to an applied electric field. This prediction requires calculating the response of the fluid to the Stokes drag forces on the moving body and on the countercharges near its surface. To determine the fluid's motion, we represent both the body and the countercharges using many point sources of drag known as stokeslets. Finding the correct flow field amounts to finding the set of drag forces on the stokeslets that is consistent with the relative velocities experienced by each stokeslet. The method rigorously satisfies the condition that the object moves with no transfer of momentum to the fluid. We demonstrate that a sphere represented by 1999 well-separated stokeslets on its surface produces flow and drag force like a solid sphere to one-percent accuracy. We show that a uniformly-charged sphere with 3998 body and countercharge stokeslets obeys the Smoluchowski prediction \cite{Morrison} for electrophoretic mobility when the countercharges lie close to the sphere. Spheres with dipolar and quadrupolar charge distributions rotate and translate as predicted analytically to four percent accuracy or better. We describe how the method can treat general asymmetric shapes and charge distributions. This method offers promise as a way to characterize and manipulate asymmetrically charged colloid-scale objects from biology (e.g. viruses) and technology (e.g. self-assembled clusters).

description: Transition-metal centers are the active sites for many biological and inorganic chemical reactions. Notwithstanding this central importance, density-functional theory calculations based on generalized-gradient approximations often fail to describe energetics, multiplet structures, reaction barriers, and geometries around the active sites. We suggest here an alternative approach, derived from the Hubbard U correction to solid-state problems, that provides an excellent agreement with correlated-electron quantum chemistry calculations in test cases that range from the ground state of Fe$_2$ and Fe$_2^-$ to the addition-elimination of molecular hydrogen on FeO$^+$. The Hubbard U is determined with a novel self-consistent procedure based on a linear-response approach.

description: Numerical simulations of the full quantum properties of interacting many-body systems by means of field-theoretic Monte-Carlo techniques are often limited due to a sign problem. Here we simulate properties of a dilute two-dimensional Bose gas in the vicinity of the Berezinskii-Kosterlitz-Thouless (BKT) transition by means of the Complex Langevin (CL) algorithm, thereby extending our previous CL study of the three-dimensional Bose gas to the lower-dimensional case. The purpose of the paper is twofold. On the one hand, it adds to benchmarking of the CL method and thus contributes to further exploring the range of applicability of the method. With the respective results, the universality of the equation of state is recovered, as well as the long-wave-length power-law dependence of the single-particle momentum spectrum below the BKT transition. Analysis of the rotational part of the current density corroborates vortex unbinding in crossing the transition. Beyond these measures of consistency we compute quantum corrections to the critical density and chemical potential in the weakly coupled regime. Our results show a shift of these quantities to lower values as compared to those obtained from classical field theory. It points in the opposite direction as compared to the shift of the critical density found by means of the path-integral Monte-Carlo method at larger values of the coupling. Our simulations widen the perspective for precision comparisons with experiment.

description: We complete the classification of (2,2) string vacua that can be constructed by diagonal twists of tensor products of minimal models with ADE invariants. Using the \LG\ framework, we compute all spectra from inequivalent models of this type. The completeness of our results is only possible by systematically avoiding the huge redundancies coming from permutation symmetries of tensor products. We recover the results for (2,2) vacua of an extensive computation of simple current invariants by Schellekens and Yankielowitz, and find 4 additional mirror pairs of spectra that were missed by their stochastic method. For the model $(1)^9$ we observe a relation between redundant spectra and groups that are related in a particular way.

description: The urban road networks of the 20 largest German cities have been analysed, based on a detailed database providing the geographical positions as well as the travel-times for network sizes up to 37,000 nodes and 87,000 links. As the human driver recognises travel-times rather than distances, faster roads appear to be 'shorter' than slower ones. The resulting metric space has an effective dimension d>2, which is a significant measure of the heterogeneity of road speeds. We found that traffic strongly concentrates on only a small fraction of the roads. The distribution of vehicular flows over the roads obeys a power law, indicating a clear hierarchical order of the roads. Studying the cellular structure of the areas enclosed by the roads, the distribution of cell sizes is scale invariant as well.

description: Throughout human history we have studied and observed all of Earth's systems (Geosphere, Biosphere, Hydrosphere, Cryosphere and Atmosphere) but too often there has been negligible integration within and between research undertaken on these Earth systems. Neither has there been much integration across the activities of observing and monitoring, storage and enabling access to data, computing and modelling tools, which is required to understand the past, present and predicted future states. The lack of integrated scientific aspirations and data/compute Research Infrastructures (RIs) has reduced the advancement of our understanding of these interdependent complex systems, particularly as data is often collected in isolation, or to address very specific research problems. The challenges to achieving such an integrated perspective are scientific, technical, social, political and organisational.

This year a group of NCRIS (and National Environmental and  Earth Scientific Facilities Forum) RIs held an Australian Academy of Science Frederick and Elizabeth White conference titled 'Integrated Earth', in order to address these issues.  Here we present the outcomes of this meeting and invite interested researchers and RI team members to have input into the White Paper that we are developing based on those outcomes.

We intend this paper to influence the development of national strategies for developing integrated data research and infrastructures to support Earth and environmental science activities in Australia. This is your chance to make sure this document reflects your views.

description: The integration of physical relationships into stochastic models is of major interest e.g. in data assimilation. Here, a multivariate Gaussian random field formulation is introduced, which represents the differential relations of the two-dimensional wind field and related variables such as streamfunction, velocity potential, vorticity and divergence. The covariance model is based on a flexible bivariate Matérn covariance function for streamfunction and velocity potential. It allows for different variances in the potentials, non-zero correlations between them, anisotropy and a flexible smoothness parameter. The joint covariance function of the related variables is derived analytically. Further, it is shown that a consistent model with non-zero correlations between the potentials and positive definite covariance function is possible. The statistical model is fitted to forecasts of the horizontal wind fields of a mesoscale numerical weather prediction system. Parameter uncertainty is assessed by a parametric bootstrap method. The estimates reveal only physically negligible correlations between the potentials. In contrast to the numerical estimator, the statistical estimator of the ratio between the variances of the rotational and divergent wind components is unbiased.

description: We detail the statistical distribution of bubble rearrangements in a sheared two-dimensional foam. Such rearrangements, known as T1 events, are vital to mechanisms resulting in flow through microscopic mechanical yielding. We find that at a constant rate of shear, the rate of occurrence of T1 events shows only small fluctuations. This rate is however seen to vary significantly with a variation in the initial configuration of bubbles constituting the foam. In addition, we detail the spatial and orientational distribution of T1 events and relate them to the distribution of stresses in the bulk of the material. Some insights into the irreversibility of the dynamics are also discussed.

description: Structured light is a key component of many modern applications, ranging from superresolution microscopy to imaging, sensing, and quantum information processing. As the utilization of these powerful tools continues to spread, the demand for technologies that enable the spatial manipulation of fundamental properties of light, such as amplitude, phase, and polarization grows further. In this respect, technologies based on liquid-crystal cells, e.g., spatial light modulators, became very popular in the last decade. However, the rapidly advancing field of integrated photonics allows entirely new routes towards beam shaping that not only outperform liquid-crystal devices in terms of speed, but also have substantial potential with respect to robustness and conversion efficiencies. In this study, we demonstrate how a programmable integrated photonic processor can generate and control higher-order free-space structured light beams at the click of a button. Our system offers lossless and reconfigurable control of the spatial distribution of light's amplitude and phase, with switching times in the microsecond domain. The showcased on-chip generation of spatially tailored light enables an even more diverse set of methods, applications, and devices that utilize structured light by providing a pathway towards combining the strengths of programmable integrated photonics and free-space structured light.

description: Experiments on physical continuum robot are the gold standard for evaluations. Currently, as no commercial continuum robot platform is available, a large variety of early-stage prototypes exists. These prototypes are developed by individual research groups and are often used for a single publication. Thus, a significant amount of time is devoted to creating proprietary hardware and software hindering the development of a common platform, and shifting away scarce time and efforts from the main research challenges.
 We address this problem by proposing an open-source actuation module, which can be used to build different types of continuum robots. It consists of a high-torque brushless electric motor, a high resolution optical encoder, and a low-gear-ratio transmission. For this letter, we create three different types of continuum robots. In addition, we illustrate, for the first time, that continuum robots built with our actuation module can proprioceptively detect external forces. Consequently, our approach opens untapped and under-investigated research directions related to the dynamics and advanced control of continuum robots, where sensing the generalized flow and effort is mandatory. Besides that, we democratize continuum robots research by providing open-source software and hardware with our initiative called the Open Continuum Robotics Project, to increase the accessibility and reproducibility of advanced methods.

Numerical modelling of the system using the Ginzburg-Landau equation with an internal Josephson coupling between the two spin components of the condensate qualitatively describes the experimental observations. We demonstrate that polariton spin bistability persists for sweep times in the range of $[10 μsec,1 sec]$ offering a promising route to spin switches and spin memory elements.

description: Linearly polarized emission is described, in general, in terms of the Stokes parameters $Q$ and $U$, from which the polarization intensity and polarization angle can be determined. Although the polarization intensity and polarization angle provide an intuitive description of the polarization, they are affected by the limitations of interferometric data, such as missing single-dish data in the u-v plane, from which radio frequency interferometric data is visualized. To negate the effects of these artefacts, it is desirable for polarization diagnostics to be rotationally and translationally invariant in the $Q$-$U$ plane. One rotationally and translationally invariant quantity, the polarization gradient, has been shown to provide a unique view of spatial variations in the turbulent interstellar medium when applied to diffuse radio frequency synchrotron emission. In this paper we develop a formalism to derive additional rotationally and translationally invariant quantities. We present new diagnostics that can be applied to diffuse or point-like polarized emission in any waveband, including a generalization of the polarization gradient, the polarization directional curvature, polarization wavelength derivative, and polarization wavelength curvature. In Paper II we will apply these diagnostics to observed and simulated images of diffuse radio frequency synchrotron emission.

description: The mechanical properties of crystals on curved substrates mix elastic, geometric and topological degrees of freedom. In order to elucidate the properties of such crystals we formulate the low-energy effective action that combines metric degrees of freedom with displacement fields and defects. We propose dualities for elasticity coupled to curved geometry formulated in terms of tensor gauge theories. We show that the metric degrees of freedom, evolving akin to linearized gravity are mapped to tensors with three indices. When coupled to crystals these degrees of freedom become gapped and, in the presence of dislocations and disclinations, multivalued. The elastic degrees of freedom remain gapless and mapped to symmetric gauge fields with two indices. In analogy with elasticity on flat space formulation we assume that the trace of the total quadrupole moment is conserved. In the dual formulation, topological defects, which act as sources for the gauge fields, are fractons or excitations with restricted mobility. This leads to generalized glide constraints that restrict both displacement and gravitational defects.

description: Two-dimensional (2D) materials have recently been the focus of extensive research. By following a similar trend as graphene, other 2D materials including transition metal dichalcogenides (MX2) and metal mono-chalcogenides (MX) show great potential for ultrathin nanoelectronic and optoelectronic devices. Despite the weak nature of interlayer forces in semiconducting MX materials, their electronic properties are highly dependent on the number of layers. Using scanning tunneling microscopy and spectroscopy (STM/STS), we demonstrate the tunability of the quasiparticle energy gap of few layered gallium selenide (GaSe) directly grown on a bilayer graphene substrate by molecular beam epitaxy (MBE). Our results show that the band gap is about 3.50 +/-0.05 eV for single-tetralayer (1TL), 3.00 +/-0.05 eV for bi-tetralayer (2TL) and 2.30 +/-0.05 eV for tri-tetralayer (3TL). This band gap evolution of GaSe, in particularly the shift of the valence band with respect to the Fermi level, was confirmed by angle-resolved photoemission spectroscopy (ARPES) measurements and our theoretical calculations. Moreover, we observed a charge transfer in GaSe/graphene van der Waals (vdW) heterostructure using ARPES. These findings demonstrate the high impact on the GaSe electronic band structure and electronic properties that can be obtained by the control of 2D materials layer thickness and the graphene induced doping.

description: Objective: Systemic glucocorticoids (SGCs) are a treatment option for severe asthma but are associated with the development of adverse events (AEs). Evidence on the extent of SGC use and the relationship between SGC dose and AE risk in severe asthma is limited. Methods: Patients with severe asthma (Global Initiative for Asthma step 4/5), with no SGC use during the <6–12 months before severe asthma determination (index date) were identified in the UK-based Clinical Practice Research Datalink database (2004–2012). Patients were assessed for SGC exposure and an incident diagnosis of an SGC-related AE (cataracts, diabetes, myocardial infarction [MI], osteoporosis, peptic ulcer or stroke) during the 8-year observation phase. The dose-related risk of an SGC-related AE was determined using AE-specific Cox proportional hazards models. Results: Overall, 75% of 60,418 patients identified with severe asthma received SGC during the 8-year follow-up, with the majority receiving an average of >0–≤2.5 mg/day. The risk of diabetes (hazard ratio [HR]:1.20 [95% confidence interval (CI): 1.11, 1.30]), MI (HR: 1.25 [95% CI: 1.09, 1.43]) and osteoporosis (HR: 1.64 [95% CI: 1.51, 1.78]) was increased at low SGC doses (0–2.5 mg/day), with further risk increases at doses >2.5 mg/day versus no SGC use. Compared with no SGC use, SGC increased the risk of peptic ulcer in a non-dose-dependent manner, but the risk of stroke was unchanged. Conclusions: Most patients with severe asthma are exposed to SGC, which increases SGC-related AE risk. This suggests that SGC exposure should be minimized as recommended by asthma treatment guidelines.

description: The magnetic response and fluxoid transitions of superconducting aluminum rings of various sizes, deposited under conditions likely to generate a layered structure, show good agreement with a two-order-parameter Ginzburg-Landau model. For intermediate couplings, we find metastable states that have different phase winding numbers around the ring in each of the two order parameters. Those states, previously theoretically predicted, are analogous to fractional vortices in singly connected samples with two-order-parameter superconductivity. Larger coupling locks the relative phase so that the two order parameters are only manifest in the temperature dependence of the response. With increasing proximitization, this signature gradually disappears.

Visible & reusable workflows
Creators: name: Gustafsson, Johan
Publisher: name: Zenodo
Year: 2023
Subjects: workflows

description: Computational workflows are absolutely critical to contemporary science, particularly in bioinformatics, which requires complex multistep analyses to draw meaning from data. Workflows exist on a spectrum ranging from heterogeneous composites of code - in bash scripts and interactive notebooks - that are often modified on-the-fly for bespoke or interactive analyses - through to production level pipelines managed by a workflow management system  that enable portability, reproducibility and robustness across multiple computational infrastructures. Regardless of where a workflow sits on this spectrum, its development requires expertise and time to be invested in the build, testing, and documentation, as well as deployment and optimisation for target computational infrastructure. This investment increases as a workflow moves towards a mature production level artefact.

This importance, complexity and the cost of creation underpins the need to make workflows FAIR (findable, accessible, interoperable and reusable), but also to make sure they are visible, first class digital outputs of research. In this presentation, we will describe the ecosystem of platforms, services and practices that can be leveraged by workflow developers to make their work visible, FAIR, and citable. We will also highlight the role that e-infrastructures play in supporting this ecosystem, by integrating best practice community standards for workflow description, annotation and execution with the reality of deploying workflows to a heterogeneous network of institutional and national computational endpoints. Examples of this include adopting Galaxy and Nextflow community best practices, collaborating directly with registries like WorkflowHub, and supporting enabling services for Australia: Galaxy and Nextflow Tower.

description: Metadata is a key cornerstone of research data management. However, the proper use of metadata forboth developers and users is not yet sufficiently developed. This deliverable shall present the currentstate of technical requirements that we encourage as NFDI4Energy. Its goal is to create guidancewithin the energy domain on how to interact with metadata and how to build systems and repositoriesthat handle metadata. We also reflect on these kinds of requirements from other NFDI consortia,to show the similarities and differences that might arise from the different maturity and use casesthroughout the different domains. The presented requirements reflect the state at the publicationdate, but will be further updated and evolved in the GitHub1 repository that serves as a metadatarequirement collection platform (https://github.com/NFDI4Energy/metadata-requirements).The repository is also meant for collecting requirements about metadata modules that are specific tocertain dataset types. This requirement collection process will continue in the community over thenext years. In order to contribute, use the GitHub issues in the repository to make your improvementideas known.

Wilson loops in four-dimensional quantum gravity

subject: FOS: Physical sciences

description: A Wilson loop is defined, in 4-D pure Einstein gravity, as the trace of the holonomy of the Christoffel connection or of the spin connection, and its invariance under the symmetry transformations of the action is showed (diffeomorphisms and local Lorentz transformations). We then compute the loop perturbatively, both on a flat background and in the presence of an external source; we also allow some modifications in the form of the action, and test the action of ``stabilized'' gravity. A geometrical analysis of the results in terms of the gauge group of the euclidean theory, $SO(4)$, leads us to the conclusion that the correspondent statistical system does not develope any configuration with localized curvature at low temperature. This ``non-local'' behavior of the quantized gravitational field strongly contrasts with that of usual gauge fields. Our results also provide an explanation for the absence of any invariant correlation of the curvature in the same approximation.

description: It has been recently noted that for a class of dynamical systems with explicit conservation laws represented via projector operators the dynamics can be understood in terms of lower dimensional equations This is the case for instance of memristive circuits Memristive systems are important classes of devices with wide ranging applications in electronic circuits artificial neural networks and memory storage We show that such mean field theories can emerge from averages over the group of orthogonal matrices interpreted as cycle preserving transformations applied to the projector operator describing Kirchhoffs laws Our results provide insights into the fundamental principles underlying the behavior of resistive and memristive circuits and highlight the importance of conservation laws for their meanf ield theories In addition we argue that our results shed light on the nature of the critical avalanches observed in quasi-two dimensional nanowires as boundary phenomena

description: Introduction Cardiovascular disease (CVD) is increasingly becoming a concern in breast cancer survivors (1). Factors associated with CVD risk factors were determined among breast cancer patients Method Total of 2127 women newly diagnosed with breast cancer were prospectively recruited from four tertiary hospitals in Malaysia Demographic and medical data were collected through interviews and verified with medical records. Height, weight, blood pressure, serum glucose, and lipid profiles were measured. Multivariable logistic regression analysis was conducted to determine factors independently associated with risk factors of CVD (hypertension, diabetes mellitus, obesity, hypercholesterolemia and low level of high-density lipoproteins (HDL)). Results Median age at diagnosis was 54 years (interquartile range: 45-62 years). Increasing age and Indian ethnicity were independently associated with most of the CVD risk factors. Breast cancer patients with higher cancer stages were significantly less likely to have hypercholesterolemia, where an inverse linear association was observed; p for trend = 0.004. Patients presenting with de novo metastatic breast cancer for instance were 50% less likely to have hypercholesterolemia compared to women presenting with stage I breast cancer (OR: 0.50, 95%CI: 0.35-0.72). Likewise, women with stage IV breast cancer were significantly more likely to have low HDL levels than women with early breast cancer (OR: 1.88, 95%CI: 1.24-2.84; p for trend = 0.004). De novo metastatic disease and ER positive breast cancers were independently associated with presence of multiple (clustering) CVD risk factors at baseline. Discussion / Conclusion Advanced cancer stage was associated with low HDL and cholesterol. ❑ Previous study reported that low-HDL-cholesterol levels among breast cancer patients were associated with more aggressive tumour characteristics and worse survival (2). While the discussion that CVD and cancer share similar pathophysiological pathways has been ongoing, further clinical research is needed to fully elucidate the association between serum lipid levels and carcinogenesis.
