description: We estimate the mass density fluctuations power spectrum (PS) on large scales by applying a maximum likelihood technique to the peculiarvelocity data of the recently completed redshift-distance survey of early-type galaxies (ENEAR). The general results are in agreement with the high amplitude power spectra found from similar analysis of other independent all-sky catalogs of peculiar velocity data such as MARK III and SFI. For Lambda & Open CDM COBE normalized PS models, the best-fit parameters are confined by a contour approximately defined by Omega h^{1.3}=0.377+-0.08 and Omega h^{0.88}=0.517+-0.083, respectively. Gamma-shape models, free of COBE normalization, resultsin the weak constraint of $Γ\geq 0.17$ and in the rather stringent constraint of sigma_8 Omega^{0.6}=1.0+-0.25. All quoted uncertainties refer to 3-sigma confidence-level. The calculated PS is used as a prior for Wiener reconstruction of the density field at different resolutions and the three-dimensional velocity field within a volume of radius ~80 Mpc/h. All major structures in the nearby universe are recovered and are well matched to those predicted from all-sky redshift surveys.

description: The pyrochlore magnet $\rm Yb_2Ti_2O_7$ has been proposed as a quantum spin ice candidate, a spin liquid state expected to display emergent quantum electrodynamics with gauge photons among its elementary excitations. However, $\rm Yb_2Ti_2O_7$'s ground state is known to be very sensitive to its precise stoichiometry. Powder samples, produced by solid state synthesis at relatively low temperatures, tend to be stoichiometric, while single crystals grown from the melt tend to display weak "stuffing" wherein $\mathrm{\sim 2\%}$ of the $\mathrm{Yb^{3+}}$, normally at the $A$ site of the $A_2B_2O_7$ pyrochlore structure, reside as well at the $B$ site. In such samples $\mathrm{Yb^{3+}}$ ions should exist in defective environments at low levels, and be subjected to crystalline electric fields (CEFs) very different from those at the stoichiometric $A$ sites. New neutron scattering measurements of $\mathrm{Yb^{3+}}$ in four compositions of $\rm Yb_{2+x}Ti_{2-x}O_{7-y}$, show the spectroscopic signatures for these defective $\mathrm{Yb^{3+}}$ ions and explicitly demonstrate that the spin anisotropy of the $\mathrm{Yb^{3+}}$ moment changes from XY-like for stoichiometric $\mathrm{Yb^{3+}}$, to Ising-like for "stuffed" $B$ site $\mathrm{Yb^{3+}}$, or for $A$ site $\mathrm{Yb^{3+}}$ in the presence of an oxygen vacancy.

description: Over the past few years, a number of surveys and other studies have solicited feedback from academics, researchers, and other scholarly communication stakeholders in various countries and regions about access to research journals and/or data. These include two surveys carried out by the European Commission (EC); one by CIBER, which was commissioned and funded by JISC, the Publishing Research Consortium (PRC) and the Research Information Network (RIN); another by Outsell, commissioned by the libraries of the Australian Group of Eight Universities (Go8); and, most recently, the two Requests for Information (RFI) on public access to scholarly journals, issued by the US Office of Science & Technology Policy (OSTP). This article is an attempt to identify the common themes across all five studies, to address some seemingly contradictory findings, and to suggest some best practices for future surveys of this kind – especially important given that their findings are increasingly used to inform policy decisions which may have a major impact on some or all scholarly communication key stakeholders

description: We have detected a bright X-ray flare from the nearby brown dwarf LP 944-20 with the Chandra/ACIS-S. This is an old (500 Myr), rapidly rotating, lithium-bearing M9 object, with a bolometric luminosity of 6e29 ergs cm-2 s-1. It was only detected by Chandra during an X-ray flare of duration 1-2 hours near the end of a 12.1 hour observation. The peak X-ray luminosity was 1.2(+0.5/-0.3)e26 ergs cm-2 s-1 in the brightest ~550 seconds, corresponding to Lx/Lbol ~ 2e-4. A total of 2e29 ergs was released during the 43,773 sec observation, giving a time-averaged Lx/Lbol ~ 7e-6. LP 944-20 was not detected before the flare, with a 3 sigma upper limit on the emission at Lx/Lbol < 2e-6 (Lx<1e24 ergs cm-2 s-1). This is faint for a rapidly rotating late-type star, and establishes a record lower limit to the quiescent flux about an order of magnitude below the flux limit (and a factor of 5 below the Lx/Lbol limit) placed on quiescent X-ray emission from the M8 dwarf VB 10. The inferred flaring duty cycle is comparable to that measured via variable H-alpha emission for other late M-type, fully convective stars.

title: Assessing dose–response relationships for endocrine disrupting chemicals (EDCs): a focus on non-monotonicity
Creators: name: Zoeller, Robert T
name: Vandenberg, Laura N
Publisher: name: University of Massachusetts Amherst
Year: 2015

description: The fundamental principle in regulatory toxicology is that all chemicals are toxic and that the severity of effect is proportional to the exposure level. An ancillary assumption is that there are no effects at exposures below the lowest observed adverse effect level (LOAEL), either because no effects exist or because they are not statistically resolvable, implying that they would not be adverse. Chemicals that interfere with hormones violate these principles in two important ways: dose–response relationships can be non-monotonic, which have been reported in hundreds of studies of endocrine disrupting chemicals (EDCs); and effects are often observed below the LOAEL, including all environmental epidemiological studies examining EDCs. In recognition of the importance of this issue, Lagarde et al. have published the first proposal to qualitatively assess non-monotonic dose response (NMDR) relationships for use in risk assessments. Their proposal represents a significant step forward in the evaluation of complex datasets for use in risk assessments. Here, we comment on three elements of the Lagarde proposal that we feel need to be assessed more critically and present our arguments: 1) the use of Klimisch scores to evaluate study quality, 2) the concept of evaluating study quality without topical experts’ knowledge and opinions, and 3) the requirement of establishing the biological plausibility of an NMDR before consideration for use in risk assessment. We present evidence-based logical arguments that 1) the use of the Klimisch score should be abandoned for assessing study quality; 2) evaluating study quality requires experts in the specific field; and 3) an understanding of mechanisms should not be required to accept observable, statistically valid phenomena. It is our hope to contribute to the important and ongoing debate about the impact of NMDRs on risk assessment with positive suggestions.

QCD Sum Rule for S_{11}(1535)

description: We propose a new interpolating field for S$_{11}$(1535) to determine its mass from QCD sum rules. In the nonrelativistic limit, this interpolating field dominantly reduces to two quarks in the s-wave state and one quark in the p-wave state. An optimization procedure, which makes use of a duality relation, yields the interpolating field which overlaps strongly with the negative-parity baryon and at the same time does not couple at all to the low lying positive-parity baryon. Using this interpolating field and applying the conventional QCD sum rule analysis, we find that the mass of S$_{11}$ is reasonably close to the experimentally known value, even though the precise determination depends on the poorly known quark-gluon condensate. Hence our interpolating field can be used to investigate the spectral properties of S$_{11}$(1535).

description: En uno de los mejores ensayos que se ha escrito sobre las dos novelas más sobresalientes de Alejandro Tapia y Rivera (Puerto Rico, 1826-1882), Póstumo, el transmigrado (1872) y Póstumo, el envirginiado (1882), Marta Aponte Alsina explica que “[…e]l conjunto de temas esotéricos plantea, en un nivel interpretativo elemental, la problemática de la identidad” (46). Inmediatamente, Aponte Alsina comenta sobre cómo Tapia utilizó el motivo del doble (Dopplegänger) y del esoterismo, entre muchas de sus estrategias, para explorar el tema de las identidades.1 Añadiría a esto que Tapia y Rivera también se vale de un agudo sentido del humor para llevar a cabo una observación crítica sobre las diferencias sociales y políticas tanto en España como en el Puerto Rico de finales del siglo XIX. Tal sentido del humor ayuda a Tapia a explorar las contradicciones inherentes a una ciudadanía emergente en el contexto de los procesos de modernización, pero otorgándole una cierta carga de liviandad a la seriedad del asunto: la vida es una broma muy seria. Más adelante, en su lúcido ensayo y en referencia al contradictorio personaje de Póstumo, la misma autora señala:

description: The intrinsic spin-Hall effect on spin accumulation and electric conductance in a diffusive regime of a 2D electron gas has been studied for a 2D strip of a finite width. It is shown that the spin polarization near the flanks of the strip, as well as the electric current in the longitudinal direction exhibit damped oscillations as a function of the width and strength of the Dresselhaus spin-orbit interaction. Cubic terms of this interaction are crucial for spin accumulation near the edges. As expected, no effect on the spin accumulation and electric conductance have been found in case of Rashba spin-orbit interaction.

description: Over the past few years, federal funding agencies have been suggesting in a variety of venues that the time for more strict data management and data sharing mandates was coming soon. Indeed, in early 2011 the National Science Foundation released its requirements for data management planning. Other agencies and programs have followed suit over the past year, culminating in last month’s announcement by the White House Office of Science and Technology Policy that all Federal Agencies with significant research and development programs would be on the hook for mandating and facilitating data curation by their grantholders. Following the 2011 NSF mandate, many academic libraries and research management entities at universities across the U.S. have turned an eye towards offering research data management services to academic researchers. These services have taken many forms depending on available resources, extant infrastructure, institutional commitment, and needs of local researchers, among other consideration. Starting in early 2012, Carnegie Mellon University (CMU) University Libraries initiated an investigation into providing research data services to the university research community. Over the past year, the University Libraries, along with other collaborators at the university, have developed a plan for implementing a suite of data management services and have begun to roll out the first tier of these services. In this document we describe the process by which we developed our approach to data management services at CMU and the direction we expect to move in coming months and years.
Observation of "Topological" Microflares in the Solar Atmosphere

description: We report on observation of the unusual kind of solar microflares, presumably associated with the so-called "topological trigger" of magnetic reconnection, which was theoretically suggested long time ago by Gorbachev et al. (Sov. Ast. 1988, v.32, p.308) but has not been clearly identified so far by observations. As can be seen in pictures by Hinode SOT in CaII line, there may be a bright loop connecting two sunspots, which looks at the first sight just as a magnetic field line connecting the opposite poles. However, a closer inspection of SDO HMI magnetograms shows that the respective arc is anchored in the regions of the same polarity near the sunspot boundaries. Yet another peculiar feature is that the arc flashes almost instantly as a thin strip and then begins to expand and decay, while the typical chromospheric flares in CaII line are much wider and propagate progressively in space. A qualitative explanation of the unusual flare can be given by the above-mentioned model of topological trigger. Namely, there are such configurations of the magnetic sources on the surface of photosphere that their tiny displacements result in the formation and fast motion of a 3D null point along the arc located well above the plane of the sources. So, such a null point can quickly ignite a magnetic reconnection along the entire its trajectory. Pictorially, this can be presented as flipping the so-called two-dome magnetic-field structure (which is just the reason why such mechanism was called topological). The most important prerequisite for the development of topological instability in the two-dome structure is a cruciform arrangement of the magnetic sources in its base, and this condition is really satisfied in the case under consideration.

description: We compute (as functions of the shape and Wilson-line moduli) the one-loop Casimir energy induced by higher-dimensional supergravities compactified from 6D to 4D on 2-tori, and on some of their Z_N orbifolds. Detailed calculations are given for a 6D scalar field having an arbitrary 6D mass m, and we show how to extend these results to higher-spin fields for supersymmetric 6D theories. Particular attention is paid to regularization issues and to the identification of the divergences of the potential, as well as the dependence of the result on m, including limits for which m^2 A<< 1 and m^2 A>> 1 where A is the volume of the internal 2 dimensions. Our calculation extends those in the literature to very general boundary conditions for fields about the various cycles of these geometries. The results have potential applications towards Supersymmetric Large Extra Dimensions (SLED) as a theory of the Dark Energy. First, they provide an explicit calculation within which to follow the dependence of the result on the mass of the bulk states which travel within the loop, and for heavy masses these results bear out the more general analysis of the UV-sensitivity obtained using heat-kernel methods. Second, because the potentials we find describe the dynamics of the classical flat directions of these compactifications, within SLED they would describe the present-day dynamics of the Dark Energy.

Creators: name: Verma, Vikash

Publisher: name: University of Massachusetts Amherst
Year: 2019
Subjects: subject: Biology

description: Microtubules (MTs) are essential for cleavage furrow positioning during cytokinesis, but the mechanisms by which MT-derived signals spatially define regions of cortical contractility are unresolved. In this study cytokinesis regulators visualized in Drosophila melanogaster (Dm) cells were found to localize to and track MT plus-ends during cytokinesis. The RhoA GEF Pebble (Dm ECT2) did not evidently tip-track, but rather localized rapidly to cortical sites contacted by MT plus-tips, resulting in RhoA activation and enrichment of myosin-regulatory light chain. The MT plus-end localization of centralspindlin was compromised following EB1 depletion, which resulted in a higher incidence of cytokinesis failure. Centralspindlin plus-tip localization depended on the C-terminus and a putative EB1-interaction motif (hxxPTxh) in RacGAP50C. We propose that MT plus-end-associated centralspindlin recruits a cortical pool of Dm ECT2 upon physical contact to activate RhoA and to trigger localized contractility.

description: We report the high resolution resonant inelastic EUV scattering study of quantum Heisenberg antiferromagnet KCoF3. By tuning the EUV photon energy to cobalt M23 edge, a complete set of low energy 3d spin-orbital excitations is revealed. These low-lying electronic excitations are modeled using an extended multiplet-based mean field calculation to identify the roles of lattice and magnetic degrees of freedom in modifying the RIXS spectral lineshape. We have demonstrated that the temperature dependence of RIXS features upon the antiferromagnetic ordering transition enables us to probe the energetics of short-range spin correlations in this material.

description: We present X-ray emission line equivalent width images of the bright Galactic supernova remnant Cassiopeia A for the elements Si, S, Ar, Ca, and Fe using a 50,000 s observation with the Advanced CCD Imaging Spectrometer on the Chandra X-ray Observatory. The images essentially identify the bulk of detectable ejecta of these elements over a wide range of surface brightness, and show morphologies distinctly different from that of the broadband X-ray emission and of the 4-6 keV continuum emission. The Si, S, Ar, and Ca maps, while different in turn from those of Fe, show that these X-ray emitting ejecta are distributed similarly to the fast optical ejecta knots, and clearly delineate the X-ray counterpart of the northeast optical jet. Low surface brightness regions just outside the bright shell in the north and west are also shown to have strong line emission. The strong Fe emission is exterior to that of other elements in the east, as previously noted, but is generally coincident elsewhere. The projected interior has relatively little emission traced by high line equivalent widths.

description: Many networks are characterized by highly heterogeneous distributions of links, which are called scale-free networks and the degree distributions follow $p(k)\sim ck^{-α}$. We study the robustness of scale-free networks to random failures from the character of their heterogeneity. Entropy of the degree distribution can be an average measure of a network's heterogeneity. Optimization of scale-free network robustness to random failures with average connectivity constant is equivalent to maximize the entropy of the degree distribution. By examining the relationship of entropy of the degree distribution, scaling exponent and the minimal connectivity, we get the optimal design of scale-free network to random failures. We conclude that entropy of the degree distribution is an effective measure of network's resilience to random failures.

description: Humans have been able to tackle biosphere complexities by acting as ecosystem engineers, profoundly changing the flows of matter, energy and information. This includes major innovations that allowed to reduce and control the impact of extreme events. Modelling the evolution of such adaptive dynamics can be challenging given the potentially large number of individual and environmental variables involved. This paper shows how to address this problem by using fire as the source of external, bursting and wide fluctuations. We implement a simulated environment where fire propagates on a spatial landscape and a group of artificial agents learn how to harvest and exploit trees while avoiding the damaging effects of fire spreading. The agents need to solve a conflict to reach a group-level optimal state: while tree harvesting reduces the propagation of fires, it also reduces the availability of resources provided by trees. It is shown that the system displays two major evolutionary innovations that end up in an ecological engineering strategy that favours high biomass along with the suppression of large fires. The implications for potential A.I. management of complex ecosystems are discussed.

description: Timing observations of 40 mostly young pulsars using the ATNF Parkes radio telescope between 1990 January and 1998 December are reported. In total, 20 previously unreported glitches and ten other glitches were detected in 11 pulsars. These included 12 glitches in PSR J1341$- $6220, corresponding to a glitch rate of 1.5 glitches per year. We also detected the largest known glitch, in PSR J1614$-$5047, with $Δν_g/ν\approx 6.5 \times 10^{-6}$ where $ν= 1/P$ is the pulse frequency. Glitch parameters were determined both by extrapolating timing solutions to inter-glitch intervals and by phase-coherent timing fits across the glitch(es). Analysis of glitch parameters, both from this work and from previously published results, shows that most glitches have a fractional amplitude $Δν_g/ν$ of between $10^{-8}$ and $10^{-6}$. There is no consistent relationship between glitch amplitude and the time since the previous glitch or the time to the following glitch, either for the ensemble or for individual pulsars. As previously recognised, the largest glitch activity is seen in pulsars with ages of order 10$^4$ years, but for about 30 per cent of such pulsars, no glitches were detected in the 8-year data span. There is some evidence for a new type of timing irregularity in which there is a significant increase in pulse frequency over a few days, accompanied by a decrease in the magnitude of the slowdown rate. Fits of an exponential recovery to post-glitch data show that for most older pulsars, only a small fraction of the glitch decays. In some younger pulsars, a large fraction of the glitch decays, but in others, there is very little decay.

description: A continuum approach to the three valence-quark bound-state problem in quantum field theory is used to perform a comparative study of the four lightest $(I=1/2,J^P = 1/2^\pm)$ baryon isospin-doublets in order to elucidate their structural similarities and differences. Such analyses predict the presence of nonpointlike, electromagnetically-active quark-quark (diquark) correlations within all baryons; and in these doublets, isoscalar-scalar, isovector-pseudovector, isoscalar-pseudoscalar, and vector diquarks can all play a role. In the two lightest $(1/2,1/2^+)$ doublets, however, scalar and pseudovector diquarks are overwhelmingly dominant. The associated rest-frame wave functions are largely $S$-wave in nature; and the first excited state in this $1/2^+$ channel has the appearance of a radial excitation of the ground state. The two lightest $(1/2,1/2^-)$ doublets fit a different picture: accurate estimates of their masses are obtained by retaining only pseudovector diquarks; in their rest frames, the amplitudes describing their dressed-quark cores contain roughly equal fractions of even- and odd-parity diquarks; and the associated wave functions are predominantly $P$-wave in nature, but possess measurable $S$-wave components. Moreover, the first excited state in each negative-parity channel has little of the appearance of a radial excitation. In quantum field theory, all differences between positive- and negative-parity channels must owe to chiral symmetry breaking, which is overwhelmingly dynamical in the light-quark sector. Consequently, experiments that can validate the contrasts drawn herein between the structure of the four lightest $(1/2,1/2^\pm)$ doublets will prove valuable in testing links between emergent mass generation and observable phenomena and, plausibly, thereby revealing dynamical features of confinement.

description: The nonextensive kinetic theory for degenerate quantum gases is discussed in the general relativistic framework. By incorporating nonadditive modifications in the collisional term of the relativistic Boltzmann equation and entropy current, it is shown that Tsallis entropic framework satisfies a H-theorem in the presence of gravitational fields. Consistency with the 2nd law of thermodynamics is obtained only whether the entropic q-parameter lies in the interval $q \in [0,2]$. As occurs in the absence of gravitational fields, it is also proved that the local collisional equilibrium is described by the extended Bose-Einstein (Fermi-Dirac) q-distributions.

description: The Gribov copies and their consequences on the infrared behavior of the gluon propagator are investigated in Euclidean Yang-Mills theories quantized in linear covariant gauges. Considering small values of the gauge parameter, it turns out that the transverse component of the gluon propagator is suppressed, while its longitudinal part is left unchanged. A Green function, G_{tr}, which displays infrared enhancement and which reduces to the ghost propagator in the Landau gauge is identified. The inclusion of the dimension two gluon condensate is also considered. In this case, the transverse component of the gluon propagator and the Green function G_{tr} remain suppressed and enhanced, respectively. Moreover, the longitudinal part of the gluon propagator becomes suppressed. A comparison with the results obtained from the studies of the Schwinger-Dyson equations and from lattice simulations is provided.

description: Clustering samples according to an effective metric and/or vector space representation is a challenging unsupervised learning task with a wide spectrum of applications. Among several clustering algorithms, k-means and its kernelized version have still a wide audience because of their conceptual simplicity and efficacy. However, the systematic application of the kernelized version of k-means is hampered by its inherent square scaling in memory with the number of samples. In this contribution, we devise an approximate strategy to minimize the kernel k-means cost function in which the trade-off between accuracy and velocity is automatically ruled by the available system memory. Moreover, we define an ad-hoc parallelization scheme well suited for hybrid cpu-gpu state-of-the-art parallel architectures. We proved the effectiveness both of the approximation scheme and of the parallelization method on standard UCI datasets and on molecular dynamics (MD) data in the realm of computational chemistry. In this applicative domain, clustering can play a key role for both quantitively estimating kinetics rates via Markov State Models or to give qualitatively a human compatible summarization of the underlying chemical phenomenon under study. For these reasons, we selected it as a valuable real-world application scenario.

description: Pathogens are one of the factors driving pollinator declines. Diet can play an important role in mediating pollinator health and resistance to pathogens. Sunflower pollen (Helianthus annuus) dramatically reduced a gut pathogen (Crithidia bombi) of Bombus impatiens previously, but the breadth of this effect was unknown. We tested whether pollen from nine H. annuus cultivars, four wild H. annuus populations, H. petiolarus, H. argophyllus and two Solidago spp., reduced Crithidia in B. impatiens compared to mixed wildflower pollen and buckwheat pollen (Fagopyrum esculentum) as controls. We also compared hand- and honeybee-collected pollen (which contains nectar) to assess whether diet effects on pathogens were due to pollen or nectar. All Helianthus and Solidago pollen reduced Crithidia by 20–40-fold compared to buckwheat pollen, and all but three taxa reduced Crithidia compared to wildflower pollen. We found no consistent differences between hand- and bee-collected pollen, suggesting that pollen alone can reduce Crithidia infection. Our results indicate an important role of pollen diet for bee health and potentially broad options within the Asteraceae for pollinator plantings to manage bee disease.
The Anglo-Saxon Preference toward High-rise Buildings inspired by Italian Medieval Towers between the 19th and 20th Centuries

description: Between the 19th and 20th centuries, the architecture of city halls often chose to incorporate a tower, as a symbol of administrative power, while towers of commercial buildings indicated financial power. Fire stations had a tower suitable for watching over the city and railway stations or universities had clock towers. Anglo-Saxon architects designed towers inspired by Italian medieval examples, while many British shafts and chimneys imitated Italian bell towers and the first American skyscrapers were also inspired by the aforementioned Italian towers.

description: Using a relativistic transport model to describe the expansion of the fire-cylinder formed in the initial stage of heavy-ion collisions at SPS/CERN energies, we study the production of dileptons with mass below about 1 GeV from these collisions. The initial hadron abundance and their momentum distributions in the fire-cylinder are determined by following the general features of the results from microscopic models based on the string dynamics and further requiring that the final proton and pion spectra and rapidity distributions are in agreement with available experimental data. For dilepton production, we include the Dalitz decay of $π^0$, $η$, $η^\prime$, $ω$ and $a_1$ mesons, the direct decay of primary $ρ^0$, $ω$ and $ϕ$ mesons, and the pion-pion annihilation that proceeds through the $ρ^0$ meson, the pion-rho annihilation that proceeds through the $a_1$ meson, and the kaon-antikaon annihilation that proceeds through the $ϕ$ meson. We find that the modification of vector meson properties, especially the decrease of their mass due to the partial restoration of chiral symmetry, in hot and dense hadronic matter, provides a quantitative explanation of the recently observed enhancement of low-mass dileptons by the CERES collaboration in central S+Au collisions and by the HELIOS-3 collaboration in central S+W collisions.

description: Permanent magnet materials require a high uniaxial magneto-crystalline anisotropy. Exchange coupling between small crystallites with easy-plane anisotropy induces an effective uniaxial anisotropy if arranged accordingly. Nanostructuring of materials with easy-plane anisotropy is an alternative way to create hard-magnetic materials. The coercivity increases with decreasing feature size. The resulting coercive field is about 12 percent of the anisotropy field for a crystal size of 3.4 times the Bloch parameter.

description: Let $G$ be a semisimple Lie group with a maximal torus $T$. We present an explicit formula for the Borel transgression $τ:H^{1}(T)\rightarrow H^{2}(G/T)$ of the fibration $G\rightarrow G/T$. This formula corrects an error in the paper \cite{K}, and has been applied to construct the integral cohomology rings of compact Lie groups in the sequel works \cite{D,DZ2}.

description: Medical diagnostic testing can be made significantly more efficientusing pooled testing protocols. These typically require a sparse infection signaland use either binary or real-valued entries of O(1). However, existing methodsdo not allow for inferring viral loads which span many orders of magnitude. Wedevelop a message passing algorithm coupled with a PCR (Polymerase ChainReaction) specific noise function to allow accurate inference of realistic viral loadsignals. This work is in the non-adaptive setting and could open the possibilityof efficient screening where viral load determination is clinically important.

Emerging Scathed: A Critical Analysis of Current Approaches to Domestic Violence – Fusing Punitive & Restorative Solutions
Creators: name: Tsagas, Mark
Publisher: name: School of Education & Communities, University of East London
Year: 2022

description: As the UK is taking steps to emerge from Covid-19 pandemic related restrictions, the tail-end of the pandemic itself seemingly in sight, as people, a Nation, residents of this world, we are faced with certain grim realities. One such reality, is the knowledge that during the extended lockdown period there was a substantial increase in ‘police recorded domestic abuse crimes’ (Ivandic, Kirchmaeir and Linton, 2021). Specifically, Refuge and Respect, charities against domestic violence, submitted, in a BBC report, an astounding 60-70% increase in reports of domestic violence to their call centres from female and male victims respectively, during the initial period of lockdown, describing it as an ‘epidemic beneath a pandemic’ (June, 2021). In a quick turn of events, present Government responded quickly. Not only was additional funding provided to preventative and reporting services, but new legislation was passed, the Domestic Abuse Act 2021, helping to illustrate and cement the seriousness of domestic violence. Yet, despite their efforts, both the legislation passed, and the funding provided should not, in fact, serve as the end-goal for the cause. Rather, as cornerstones of a movement, they should pave the way for additional survivor-centred approaches to take root. The newly enacted legislation purports to be supportive of a legal approach predominantly punitive in nature, focusing on the offender, rather than restorative thus aiming to rectify the harm afflicted upon the victims of domestic abuse. The article at hand will attempt to illustrate how overemphasis on a punitive approach might not necessarily be in the public’s best interest. Acknowledging the legislation’s marginal attempts at a dual approach, a further attempt will be made to critically analyse current measures and how while they may be a significant step in the right direction, better provisions could have been enacted in certain circumstances. On a final note, an effort will be made to demonstrate how specific restorative practices can be highly beneficial in dealing with certain instances of domestic violence, when utilised in tandem with the current punitive approach.

description: In this paper we analyse the benefits of incorporating interval-valued fuzzy sets into the Bousi-Prolog system. A syntax, declarative semantics and im- plementation for this extension is presented and formalised. We show, by using potential applications, that fuzzy logic programming frameworks enhanced with them can correctly work together with lexical resources and ontologies in order to improve their capabilities for knowledge representation and reasoning.
