description: Many structures in nature are invariant under the transformation (p,r)->(br,-p/b), where b is some scale factor. Born's reciprocity hypothesis affirms that this invariance extends to the entire Hamiltonian and equations of motion. We investigate this idea for atomic physics and galactic motion, where one is basically dealing with a 1/r potential and the observations are very accurate, so as to determine the scale $b = mΩ$. We find that an $Ω\sim 1.5\times 10^{-15}$ Hz has essentially no effect on atomic physics but might possibly offer an explanation for galactic rotation, without invoking dark matter.

description: LaFeAsO1-xFx thin films were deposited successfully on (001)-oriented LaAlO3 and MgO substrates from stoichiometric LaFeAsO1-xFx polycrystalline targets with fluorine concentrations up to x = 0.25 by PLD. Room temperature deposition and post annealing of the films yield nearly phase pure films with a pronounced c-axis texture and a strong biaxial in-plane orientation. Transport measurements show metallic resistance and onset of superconductivity at 11 K. Hc2(T) was determined by resistive measurements and yield Hc2 values of 3 T at 3.6 K for B||c and 6 T at 6.4 K for B||ab.

description: We explore the dynamics of a ``cluster wind'' flow in the regime in which the shocks resulting from the interaction of winds from nearby stars are radiative. We first show that for a cluster with T Tauri stars and/or Herbig Ae/Be stars, the wind interactions are indeed likely to be radiative. We then compute a set of four, three dimensional, radiative simulations of a cluster of 75 young stars, exploring the effects of varying the wind parameters and the density of the initial ISM that permeates the volume of the cluster. These simulations show that the ISM is compressed by the action of the winds into a structure of dense knots and filaments. The structures that are produced resemble in a qualitative way the observations of the IRAS 18511+0146 of Vig et al. (2007).

Sustainability

description: Among 1+MG signatory countries, it is agreed to collectively develop a cohort of at least one million European citizens that have their genome determined via Whole Genome Sequencing (WGS). The goal is to make the personal genomic data and associated health information accessible in a secure manner for the different purposes in health care (prevention, diagnostics and therapy), research and innovation, and public health. To achieve this goal, the Beyond 1 Million Genomes Project (B1MG), will provide a set of recommendations for the long-term sustainability of the initiative beyond the B1MG including guidance for countries on how to establish funding routes to ensure the establishment and maintenance of the infrastructure to enable federated cross-border access to genomic and associated phenotypic data in the long term. Long-term sustainability of the 1+MG initiative will require an appropriate organisational structure and plan. The Governing Board of B1MG will be crucial to this aim. Potential legal and financial frameworks for developing the initiative at national and international level will be explored together with its insertion/ institution as a major contributor to future initiatives. Sustainability is built on the basis of four dimensions that we will have to consider beyond the proyect and beyond this task. This four dimensions are: Financial dimension: how the initiative will be financed at European, national, local and user level. Legal dimension: how the initiative will be used in compliance with legal and data protection standards. Governance dimension: in terms of Member States involvement and legal standing of the coordination entity for cooperation of Member States. Data access dimension: related with the governance of the data and the liability of data protection. Also, particularly important, is that the initiative should work on establishing a training and education plan on e-skills for students and healthcare professionals, hospital managers and policy makers to be put in place at the same time as the infrastructure and technologies for data exchange are put in place within healthcare systems. This Policy Brief is a first document (of three) that focuses on the dimensions of financial and legal aspects of sustainability and has been elaborated with main conclusions drawn from the first policy and legal context and mapping analysis.

description: We present a new approach for obtaining very precise integration results for infrared vertex and box diagrams, where the integration is carried out directly without performing any analytic integration of Feynman parameters. Using an appropriate numerical integration routine with an extrapolation method, together with a multi-precision library, we have obtained integration results which agree with the analytic results to 10 digits even for such a very small photon mass as $10^{-150}$ GeV in the infrared vertex diagram.

description: Purpose. Elevations in initially obtained serum lactate levels are strong predictors of mortality in critically ill patients. Identifying patients whose serum lactate levels are more likely to increase can alert physicians to intensify care and guide them in the frequency of tending the blood test. We investigate whether machine learning models can predict subsequent serum lactate changes. Methods. We investigated serum lactate change prediction using the MIMIC-III and eICU-CRD datasets in internal as well as external validation of the eICU cohort on the MIMIC-III cohort. Three subgroups were defined based on the initial lactate levels: i) normal group (<2 mmol/L), ii) mild group (2-4 mmol/L), and iii) severe group (>4 mmol/L). Outcomes were defined based on increase or decrease of serum lactate levels between the groups. We also performed sensitivity analysis by defining the outcome as lactate change of >10% and furthermore investigated the influence of the time interval between subsequent lactate measurements on predictive performance. Results. The LSTM models were able to predict deterioration of serum lactate values of MIMIC-III patients with an AUC of 0.77 (95% CI 0.762-0.771) for the normal group, 0.77 (95% CI 0.768-0.772) for the mild group, and 0.85 (95% CI 0.840-0.851) for the severe group, with a slightly lower performance in the external validation. Conclusion. The LSTM demonstrated good discrimination of patients who had deterioration in serum lactate levels. Clinical studies are needed to evaluate whether utilization of a clinical decision support tool based on these results could positively impact decision-making and patient outcomes.

description: Background: Expressing breast milk has become increasingly prevalent, particularly in some developed countries. Concurrently, breast pumps have evolved to be more sophisticated and aesthetically appealing, adapted for domestic use, and have become more readily available. In the past, expressed breast milk feeding was predominantly for those infants who were premature, small or unwell; however it has become increasingly common for healthy term infants. The aim of this paper is to systematically explore the literature related to breast milk expressing by women who have healthy term infants, including the prevalence of breast milk expressing, reported reasons for, methods of, and outcomes related to, expressing.Methods: Databases (Medline, CINAHL, JSTOR, ProQuest Central, PsycINFO, PubMed and the Cochrane library) were searched using the keywords milk expression, breast milk expression, breast milk pumping, prevalence, outcomes, statistics and data, with no limit on year of publication. Reference lists of identified papers were also examined. A hand-search was conducted at the Australian Breastfeeding Association Lactation Resource Centre. Only English language papers were included. All papers about expressing breast milk for healthy term infants were considered for inclusion, with a focus on the prevalence, methods, reasons for and outcomes of breast milk expression.Results: A total of twenty two papers were relevant to breast milk expression, but only seven papers reported the prevalence and/or outcomes of expressing amongst mothers of well term infants; all of the identified papers were published between 1999 and 2012. Many were descriptive rather than analytical and some were commentaries which included calls for more research, more dialogue and clearer definitions of breastfeeding. While some studies found an association between expressing and the success and duration of breastfeeding, others found the opposite. In some cases these inconsistencies were compounded by imprecise definitions of breastfeeding and breast milk feeding.Conclusions: There is limited evidence about the prevalence and outcomes of expressing breast milk amongst mothers of healthy term infants. The practice of expressing breast milk has increased along with the commercial availability of a range of infant feeding equipment. The reasons for expressing have become more complex while the outcomes, when they have been examined, are contradictory.

description: Plane Couette flow transitions to turbulence for Re~325 even though the laminar solution with a linear profile is linearly stable for all Re (Reynolds number). One starting point for understanding this subcritical transition is the existence of invariant sets in the state space of the Navier Stokes equation, such as upper and lower branch equilibria and periodic and relative periodic solutions, that are quite distinct from the laminar solution. This article reports several heteroclinic connections between such objects and briefly describes a numerical method for locating heteroclinic connections. Computing such connections is essential for understanding the global dynamics of spatially localized structures that occur in transitional plane Couette flow. We show that the nature of streaks and streamwise rolls can change significantly along a heteroclinic connection.

description: The architecture of biological networks has been reported to exhibit high level of modularity, and to some extent, topological modules of networks overlap with known functional modules. However, how the modular topology of the molecular network affects the evolution of its member proteins remains unclear. In this work, the functional and evolutionary modularity of Homo sapiens (H. sapiens) metabolic network were investigated from a topological point of view. Network decomposition shows that the metabolic network is organized in a highly modular core-periphery way, in which the core modules are tightly linked together and perform basic metabolism functions, whereas the periphery modules only interact with few modules and accomplish relatively independent and specialized functions. Moreover, over half of the modules exhibit co-evolutionary feature and belong to specific evolutionary ages. Peripheral modules tend to evolve more cohesively and faster than core modules do. The correlation between functional, evolutionary and topological modularity suggests that the evolutionary history and functional requirements of metabolic systems have been imprinted in the architecture of metabolic networks. Such systems level analysis could demonstrate how the evolution of genes may be placed in a genome-scale network context, giving a novel perspective on molecular evolution.

description: We present new measurements of time-dependent CP asymmetries for B0 --> D(*)+D(*)- decays using (467 +/- 5) X 10^6 BB pairs collected with the BaBar detector located at the PEP-II B Factory at the Stanford Linear Accelerator Center. We determine the CP-odd fraction of the B0 --> D*+D*- decays to be R_perp = 0.158 +/- 0.028 +/- 0.006 and find CP asymmetry parameters for the CP-even component of the decay S_+ = -0.76 +/- 0.16 +/- 0.04 and C_+ = 0.00 +/- 0.12 +/- 0.02. We measure S = -0.63 +/- 0.36 +/- 0.05 and C = -0.07 +/- 0.23 +/- 0.03 for B0 --> D+D-, S = -0.62 +/- 0.21 +/- 0.03 and C = 0.08 +/- 0.17 +/- 0.04 for B0 --> D*+D-$, and S = -0.73 +/- 0.23 +/- 0.05 and C = 0.00 +/- 0.17 +/- 0.03 for B0 --> D+D*-. For the B0 --> D*+/-D-/+ decays, we also determine the CP-violating asymmetry A = 0.008 +/- 0.048 +/- 0.013. In each case, the first uncertainty is statistical and the second is systematic. The measured values for the asymmetries are all consistent with the Standard Model.

description: In otolaryngologic surgery, endoscopy is increasingly used to provide a better view of hard-to-reach areas and to promote minimally invasive surgery. However, the need to manipulate the endoscope limits the surgeon's ability to operate with only one instrument at a time. Currently, several robotic systems are being developed, demonstrating the value of robotic assistance in microsurgery. The aim of this literature review is to present and classify current robotic systems that are used for otological and endonasal applications. For these solutions, an analysis of the functionalities in relation to the surgeon's needs will be carried out in order to produce a set of specifications for the creation of new robots.

description: The dark matter puzzle is one of the most important fundamental physics questions in 21 century. There is no doubt that solving the puzzle will be a new milestone for human beings in the way of deeper understanding the mother nature. Here we propose to use the Shanghai laser electron gamma source (SLEGS) to search for dark matter candidates particles, including dark pseudo scalar particles, dark scalar particles, and dark photons. Our simulations show that electron facilities like SLEGS with some upgrading could be competitive platforms in searching for light dark matter particles with mass under tens of keV.

description: The magnetic properties of GdBaMn_{2}O_{5.0}, which exhibits charge ordering, are studied from 2 to 400 K using single crystals. In a small magnetic field applied along the easy axis, the magnetization M shows a temperature-induced reversal which is sometimes found in ferrimagnets. In a large magnetic field, on the other hand, a sharp change in the slope of M(T) coming from an unusual turnabout of the magnetization of the Mn sublattices is observed. Those observations are essentially explained by a molecular field theory which highlights the role of delicate magnetic interactions between Gd^{3+} ions and the antiferromagnetically coupled Mn^{2+}/Mn^{3+} sublattices.

description: We study numerically how multiple deformable capsules squeeze into a constriction. This situation is largely encountered in microfluidic chips designed to manipulate living cells, which are soft entities. We use fully three-dimensional simulations based on the lattice Boltzmann method to compute the flow of the suspending fluid, and on the immersed boundary method to achieve the two-way fluid-structure interaction. The mechanics of the capsule membrane elasticity is computed with the finite element method. We obtain two main states: continuous passage of the particles, and their blockage that leads to clogging the constriction. The transition from one state to another is dictated by the ratio between the size of the capsules and the constriction width, and by the capsule membrane deformability. This latter is found to enhance particle passage through narrower constrictions, where rigid particles with similar diameter are blocked and lead to clogging.

description: Network lifetime and energy consumption of data transmission have been primary Quality of Service (QoS) obligations in Wireless Sensor Networks (WSNs). The environment of a WSN is often organized into clusters to mitigate the management complexity of such obligations. However, the distance between Sensor Nodes (SNs) and the number of clusters per round are vital factors that affect QoS performance of a WSN. A designer's conundrum resolves around the desire to sustain a balance between the limited residual energy of SNs and the demand for prolonged network lifetime. Any imbalance in controlling such objectives results in either QoS penalties due to draining SN energies, or an over-cost environment that is significantly difficult to distribute and operate. Low-Energy Adaptive Clustering Hierarchy (LEACH) is a distributed algorithm proposed to tackle such difficulties. Proposed LEACH-based algorithms focus on residual energies of SNs to compute a probability function that selects cluster-heads and an optimal energy-efficient path toward a destination SN. Nevertheless, these algorithms do not consider variations in network's state at run-time. Such a state changes in an adaptive manner according to existing network structures and conditions. Thus, cluster-heads per round are not elected adaptively depending on the state and distances between SNs. This paper proposes an energy-efficient adaptive distance-based clustering called Adapt-P, in which an adaptive probability function is developed to formulate clusters. A near-optimal distance between each cluster-head and its cluster-members is formulated so that energy consumption of the network is mitigated and network lifetime is maximized. The cluster-head selection probability is adapted at the end of each round based on the maximum number of cluster-heads permitted per round found a priori and the number of alive SNs in the network.

description: Transmission, reflection and absorption of electromagnetic radiation and photon dispersion law for 2D photonic crystals with superconducting elements are studied. The calculation of optical properties of photonic crystals is studied by layer-by-layer Korringa-Kohn-Rostoker techniques. The results of numerical calculations performed for an array of superconducting cylinders have been understood in terms of a simple analytical model. The controlling of optical properties of superconducting photonic crystal by temperature and magnetic field is discussed. The variation of superconducting component density with temperature leads, particularly, to significant reduction of the transmission peaks and even to a nonmonotonous behavior of some absorbance peaks.

description: We propose a novel framework for the systematic design of lensless imaging systems based on the hyperuniform random field solutions of nonlinear reaction-diffusion equations from pattern formation theory. Specifically, we introduce a new class of imaging point-spread-functions (PSFs) with enhanced isotropic behavior and controllable sparsity. We investigate the PSFs and the modulated transfer functions (MTFs) for a number of nonlinear models and demonstrate that two-phase isotropic random fields with hyperuniform disorder are ideally suited to construct imaging PSFs with improved performances compared to PSFs based on the Perlin noise. Additionally, we introduce a phase retrieval algorithm based on the non-paraxial Rayleigh-Sommerfeld diffraction theory and introduce diffractive phase plates with PSFs designed from hyperuniform random fields, called hyperuniform phase plates (HPPs). Finally, using high-fidelity object reconstruction, we demonstrate improved image quality using engineered HPPs across the visible range. The proposed framework is suitable for high-performance lensless imaging systems for on-chip microscopy and spectroscopy applications.

Zoila sp. McNamara and Kendrick, 1994:34.
Description. Shell solid, small for genus, somewhat globose. Spire covered with callus, not projecting. Posterior canal short, notched. Anterior canal missing; slight trace of anterior basal extension on left flank. Aperture narrow, very slightly curved; outer lip with well-developed, elongate teeth (15 teeth preserved). Columellar lip with well-developed teeth extending along the whole aperture (18 teeth preserved). Base of shell rounded on both sides of aperture. Fossula well developed, concave, broad and spoon-shaped, bounded anteriorly by well-developed, single terminal ridge.
Dimensions.
Figured material. WAM 82.549, collected K. J. McNamara and G. W. Kendrick, September 1981.
Occurrence. Locality 12, Latitude Point, from large boulders of pink limestone fallen from upper level of cliff, Barrow Island, Western Australia. Poivre Formation, middle Miocene.
Remarks. This species is known only from a single specimen, which has a small piece of the left side of the posterior canal broken off, as well as a large portion of the right side of the anterior end, including the posterior canal. As a consequence, detailed comparison with other species is not possible; however, there is enough of the specimen preserved to indicate that it is a species of Zoila and almost certainly ancestral to the younger species occurring in Western Australia. Both aperture and fossula are very similar to those of Z. campestris sp. nov. from the late Pliocene, Roe Calcarenite. It differs from Z. campestris in that its outline is more rounded and it does not have a flat base. The dorsum is also not humped anteriorly as in Z. campestris sp. nov. It bears no close resemblance to any of the fossil species known from southeast Australia.
Zoila sp. is somewhat similar to the middle Pliocene species Zoila gendingensis (Martin, 1899) from the Upper Kalibeng Formation of Sonde, Java, Indonesia, but is not so high and does not have the flat base of that species. The dorsum is not as humped as in Zoila kendengensis Schilder, 1941 from the Pleistocene Putiangan Formation of Java and neither does it have the flat base of that species. Of the living species of the genus, it is most similar to Zoila venusta (Sowerby, 1846), known from the Great Australian Bight to Shark Bay, Western Australia.

description: Searches for extra spatial dimensions remain among the most popular new directions in our quest for physics beyond the Standard Model. High-energy collider experiments of the current decade should be able to find an ultimate answer to the question of their existence in a variety of models. We review these models and recent results from the Tevatron on searches for large, inverse-TeV-size, and Randall-Sundrum extra spatial dimensions. The most dramatic consequence of low-scale (~1 TeV) quantum gravity is copious production of mini-black holes at the LHC. We discuss selected topics in the mini-black-hole phenomenology.

description: Heavy-atom alkaline earth monofluoride molecules are considered as prospective systems to study spatial parity or spatial parity and time-reversal symmetry violating effects such as the nuclear anapole moment or the electron electric dipole moment. Comprehensive and highly accurate theoretical study of the electronic structure properties and transition energies in such systems can simplify the preparation and interpretation of the experiments. However, almost no attempts to calculate quantum electrodynamics (QED) effects contribution into characteristics of neutral heavy-atom molecules have been performed. Recently, we have formulated and implemented such an approach to calculate QED contributions to transition energies of molecules [L.V.~Skripnikov, J. Chem. Phys. \textbf{154}, 201101 (2021)]. In this paper, we perform a benchmark theoretical study of the transition energies in the Ba$^+$ cation and BaF molecule. The deviation of the calculated values from the experimental ones is of the order 10 cm$^{-1}$ and is more than an order of magnitude better than the "chemical accuracy", 350 cm$^{-1}$. The achievement of such an agreement has been provided in particular by the inclusion of the QED effects. The latter appeared to be not less important than the high-order correlation effects beyond the coupled cluster with single, double, and perturbative triple cluster amplitudes level. We compare the role of QED effects for transition energies with heavier molecules -- RaF and E120F, where E120 is the superheavy Z=120 homolog of Ra.

description: Human longevity in England and Wales has increased markedly in the past 50 years. But this increase has come at some very significant financial and social cost. More and more of us are having to care for our elderly parents ourselves. Careers are either put on hold or lost altogether; family incomes are much reduced; and, leisure time is lost, never to be recovered. All this care is administered without any legal entitlement to any compensation or reward. Given that the need for informal social care will rise yet further in the next few decades as the ‘baby boomer’ generation moves into old age, what can be done for this legion of family carers who hold our social care system together? Many writers have attempted to highlight this growing problem, but few, if any, have produced any viable solutions to what is an impending social crisis. This thesis investigates how English law might respond to ‘the longevity conundrum’. Through the concerted analysis of existing material, it explores, but ultimately discards, the proposal that informal carers should have the right to apply for financial provision under existing family provision legislation. It, similarly, refutes claims that informal carers might have a remedy under the law relating to unjust enrichment or through the imposition of a constructive trust on the care-receiver’s estate. Instead, it proposes – and seeks to justify – a legislative solution in the form of a mediated ‘family care contract’. Such a contract would not be a mere private affair. In practice, state funding for informal carers would need to underpin these arrangements, but, ultimately, that funding could be recovered from the private property (principally, housing) wealth that is a feature of our modern society, and the thesis then proposes how this might be done. At this point, research was undertaken through the use of semi-structured interviews to ascertain whether this process might find support from informal or ‘family’ carers. Although that research revealed an almost universal desire for change to our existing social care system for the elderly, there was little consensus over how such reforms should be funded and less what these reforms might look like. Some reflection was undertaken and comparisons were draw with certain other countries who had successfully introduced such reforms before it was concluded that public support for such reforms is unnecessary given that elsewhere these reforms have been driven by the ruling elite.

description: In type III seesaw utilized to explain the observed solar and atmospheric neutrino oscillations the Standard Model (SM) particle spectrum is extended by introducing three SU(2)_L triplet fermion fields. This can have important implications for the SM Higgs boson mass (M_H) bounds based on vacuum stability and perturbativity arguments. We compute the appropriate renormalization group equations for type III seesaw, and then proceed to identify regions of the parameter space such that the SM Higgs boson mass window is enlarged to 125 GeV < M_H < 174 GeV, with the type III seesaw scale close to TeV. We also display regions of the parameter space for which the vacuum stability and perturbativity bounds merge together for large neutrino Yukawa couplings. Comparison with type I seesaw is also presented.

description: Supernova remnants (SNRs) are thought to be the most promising sources of Galactic cosmic rays. One of the principal questions is whether they are accelerating particles up to the maximum energy of Galactic cosmic rays ($\sim$ PeV). In this work, a systematic study of gamma-ray emitting SNRs is conducted as an advanced study of Suzuki et al. 2021. Our purpose is to newly measure the evolution of maximum particle energies with increased statistics and better age estimates. We model their gamma-ray spectra to constrain the particle-acceleration parameters. Two candidates of the maximum energy of freshly accelerated particles, the gamma-ray cutoff and break energies, are found to be well below PeV. We also test a spectral model that includes both the freshly accelerated and escaping particles to estimate the maximum energies more reliably, but no tighter constraints are obtained with current statistics. The average time dependences of the cutoff energy ($\propto t^{-0.81 \pm 0.24}$) and break energy ($\propto t^{-0.77 \pm 0.23}$) cannot be explained with the simplest acceleration condition (Bohm limit), and requires shock-ISM (interstellar medium) interaction. The average maximum energy during lifetime is found to be $\lesssim 20$ TeV $(t_{\rm M}/1~{\rm kyr})^{-0.8}$ with $t_{\rm M}$ being the age at the maximum, which reaches PeV if $t_{\rm M} \lesssim 10$ yr. The maximum energies during lifetime are suggested to have a variety of 1.1--1.8 dex from object to object. Although we cannot isolate the cause of this variety, this work provides an important clue to understand the microphysics of particle acceleration in SNRs.

description: We investigate several scaling properties of a translocating homopolymer through a thin pore driven by an external field present inside the pore only using Langevin Dynamics (LD) simulation in three dimension (3D). Specifically motivated by several recent theoretical and numerical studies that are apparently at odds with each other, we determine the chain length dependence of the scaling exponents of the average translocation time, the average velocity of the center of mass, $$, the effective radius of gyration during the translocation process, and the scaling exponent of the translocation coordinate ($s$-coordinate) as a function of the translocation time. We further discuss the possibility that in the case of driven translocation the finite pore size and its geometry could be responsible that the veclocity scaling exponent is less than unity and discuss the dependence of the scaling exponents on the pore geometry for the range of $N$ studied here.

description: Background: Community-based approaches have been increasing in the effort to raise awareness and early
detection for cancer and other chronic disease. However, many times, such interventions are tested in randomized
trials, become evidence-based, and then fail to reach further use in the community. Project HEAL (Health through
Early Awareness and Learning) is an implementation trial that aims to compare two strategies of implementing
evidence-based cancer communication interventions in African American faith-based organizations.
Method: This article describes the community-engaged process of transforming three evidence-based cancer
communication interventions into a coherent, branded strategy for training community health advisors with two
delivery mechanisms. Peer community health advisors receive training through either a traditional classroom approach
(with high technical assistance/support) or a web-based training portal (with low technical assistance/support).
Results: We describe the process, outline the intervention components, report on the pilot test, and conclude with
lessons learned from each of these phases. Though the pilot phase showed feasibility, it resulted in modifications to
data collection protocols and team and community member roles and expectations.
Conclusions: Project HEAL offers a promising strategy to implement evidence-based interventions in community
settings through the use of technology. There could be wider implications for chronic disease prevention
and control.

The Trapped Polarized Fermi Gas at Unitarity

description: We consider population-imbalanced two-component Fermi gases under external harmonic confinement interacting through short-range two-body potentials with diverging s-wave scattering length. Using the fixed-node diffusion Monte Carlo method, the energies of the "normal state" are determined as functions of the population-imbalance and the number of particles. The energies of the trapped system follow, to a good approximation, a universal curve even for fairly small systems. A simple parameterization of the universal curve is presented and related to the equation of state of the bulk system.

description: Spectroscopic observations and theoretical models suggest resonant wave-particle interactions, involving high-frequency ion-cyclotron waves, as the principal mechanism for heating and accelerating ions in the open coronal holes. However, the mechanism responsible for the generation of the ion-cyclotron waves remains unclear. One possible scenario is that ion beams originating from small-scale reconnection events can drive micro-instabilities that constitute a possible source for the excitation of ion-cyclotron waves. In order to study ion beam-driven electromagnetic instabilities, the multi-fluid model in the low-beta coronal plasma is used. While neglecting the electron inertia this model allows one to take into account ion-cyclotron wave effects that are absent from the one-fluid MHD model. Realistic models of density and temperature as well as a 2-D analytical magnetic field model are used to define the background plasma in the open-field funnel region of a polar coronal hole. Considering the WKB approximation, a Fourier plane-wave linear mode analysis is employed in order to derive the dispersion relation. Ray-tracing theory is used to compute the ray path of the unstable wave as well as the evolution of the growth rate of the wave while propagating in the coronal funnel. We demonstrate that, in typical coronal holes conditions and assuming realistic values of the beam velocity, the free energy provided by the ion beam propagating parallel the ambient field can drive micro-instabilities through resonant ion-cyclotron excitation.

Structure of logarithmically divergent one-loop lattice Feynman integrals

description: For logarithmically divergent one-loop lattice Feynman integrals I(p,a), subject to mild general conditions, we prove the following expected and crucial structural result: I(p,a) = f(p)log(aM)+g(p)+h(p,M) up to terms which vanish for lattice spacing a -> 0. Here p denotes collectively the external momenta and M is a mass scale which may be chosen arbitrarily. The f(p) and h(p,M) are shown to be universal and coincide with analogous quantities in the corresponding continuum integral when the latter is regularized either by momentum cut-off or dimensional regularization. The non-universal term g(p) is shown to be a homogeneous polynomial in p of the same degree as f(p). This structure is essential for consistency between renormalized lattice and continuum formulations of QCD at one loop.
