description: Food safety is still one of the most significant public issues. Foodborne diseases, caused by pathogenic microorganisms, continue to occur worldwide. The bacterial pathogens and toxins which cause foodborne illnesses, present a threat to public health and increase the risk of significant economic losses. Poultry pathogens are of particular importance since poultry is the second-most usually consumed meat worldwide and it is considered the main source for two of the most frequent human foodborne diseases: Campylobacteriosis and Salmonellosis. According to the World Health Organisation (WHO), food insecurity causes 600 million food cases and 420,000 deaths annually. Thirty percent of deaths related to foodborne diseases occur among children under 5 years of age. WHO estimates that 33 million years of healthy individuals are lost due to the global consumption of unsafe foods each year, and this number is probably an underestimate.

description: The semantic description of music metadata is a key requirement for the creation of music datasets that can be aligned, integrated, and accessed for information retrieval and knowledge discovery. It is nonetheless an open challenge due to the complexity of musical concepts arising from different genres, styles, and periods -- standing to benefit from a lingua franca to accommodate various stakeholders (musicologists, librarians, data engineers, etc.). To initiate this transition, we introduce the Music Meta ontology, a rich and flexible semantic model to describe music metadata related to artists, compositions, performances, recordings, and links. We follow eXtreme Design methodologies and best practices for data engineering, to reflect the perspectives and the requirements of various stakeholders into the design of the model, while leveraging ontology design patterns and accounting for provenance at different levels (claims, links). After presenting the main features of Music Meta, we provide a first evaluation of the model, alignments to other schema (Music Ontology, DOREMUS, Wikidata), and support for data transformation.

description: This dataset PGA v2 is part of the Platform Governance Archive (PGA), a data repository and platform that collects and curates policies of major social media platforms in a long-term perspective. In addition to PGA v2, there is also the historical dataset PGA v1 that provides a long-term collection of platform policies of four major platforms from 2005 to 2021. The PGA v2 picks up this work and writes it into the future, while also broadening the scope of data collection. Instead of looking backward, the PGA v2 entails data collected in-real time as changes are made to platform policies. This way, the database remains always up to date allowing access to the data through the Platform Governance Archive even for the most current versions of platform policies.
Thermodynamics of SU(2) quantum Yang-Mills theory and CMB anomalies

description: A brief review of effective SU(2) Yang-Mills thermodynamics in the deconfining phase is given, including the construction of the thermal ground-state estimate in terms of an inert, adjoint scalar field $ϕ$, based on non-propagating (anti)selfdual field configurations of topological charge unity. We explain why the screening physics of an SU(2) photon is subject to an electric-magnetically dual interpretation. Next, we elucidate how a low-frequency excess of line temperature in the Cosmic Microwave Background (CMB) determines the value of the critical temperature of the deconfining-preconfining phase transition of an SU(2) Yang-Mills theory postulated to describe photon propagation, and we describe how, starting at a redshift of about unity, SU(2) photons collectively work 3D temperature depressions into the CMB. Upon projection along a line of sight, a given depression influences the present CMB sky in a cosmologically local way, possibly explaining the large-angle anomalies confirmed recently by the Planck collaboration. Finally, six relativistic polarisations residing in the SU(2) vector modes roughly match the number of degrees of freedom in cosmic neutrinos (Planck) which would disqualify the latter as radiation. Indeed, if interpreted as single center-vortex loops in confining phases of SU(2) Yang-Mills theories neutrino mass $m_ν$ solely arises by interactions with an environment. Cosmologically, the CMB represents this environment, and thus one would expect that $m_ν=ξT$ where $ξ=O(1)$. In this model cosmic neutrinos are a small dark-matter contribution, conserved only together with the CMB fluid, influencing Baryonic Acoustic Oscillations during CMB decoupling.

The Hand and the Mind, the Man and the Monster
Creators: name: Cox (Chadron State College), Kimberly
Publisher: name: Victorian Network
Year: 2016

description: This article reads the monstrous hand in Victorian fiction as a parallel for the dangerously different mind and brain. The human hand and brain were perceived by the Victorian scientific community as mutually constitutive and as having evolved in tandem, such that the hand becomes the symbol of human superiority. The hand's dexterity and sensitive nerves of touch capable of effecting the mind's ambition distinguishes it from the paws, claws, and "hands" of animals. Yet, as books on hand-phrenology reveal, not all human hands are the same. Hand-phrenologists equated manual sensitivity with intellect and brain size. The human hand that signifies the superior human intellect is traditionally English, male, educated, upper-middle class, and capable of engaging in "civilised" forms of sympathetic touch with his fellow beings. Humans distinguished themselves from the animals they evolved from with their thinking hands that both act as agents of the mind and brain and communicate knowledge of the world to them. Hands that act on the world through touch but lack the manual sensitivity necessary to facilitate such intercommunication prove monstrous in their inability to form stable social connections necessary to human progress. This article argues that monstrous hands in H. G. Wells' The Island of Doctor Moreau“ (1896), Bram Stoker's Dracula“ (1897), and H. Rider Haggard's She“ (1887) are those that initially appear human, but reveal through their dulled tactile sense and manual deformity a depraved mind with unnatural brain power. In the figure of Moreau, the monster's hand and the human hand appear interchangeable until his hand is nearly severed, reflecting his brain that sought to evolve beyond human limitation but was still bound by human failing. Monstrosity and humanity overlap in monstrous hands that parallel monstrous minds, problematising the clear boundaries that structured Victorian society and classified the people that comprised it.

description: Angle-resolved transport measurements revealed that planar defects dominate flux pinning in the investigated Co-doped BaFe2As2 thin film. For any given field and temperature, the critical current depends only on the angle between the crystallographic c-axis and the applied magnetic field but not on the angle between the current and the field. The critical current is therefore limited only by the in-plane component of the Lorentz force but independent of the out-of-plane component, which is entirely balanced by the pinning force exerted by the planar defects. This one-dimensional pinning behavior shows similarities and differences to intrinsic pinning in layered superconductors.

description: We investigate the influence of environmental noise on spin networks and spin chains. In addition to the common model of an independent bath for each spin in the system we also consider noise with a finite spatial correlation length. We present the emergence of new dynamics and decoherence-free subspaces with increasing correlation length for both dephasing and dissipating environments. This leads to relaxation blocking of one spin by uncoupled surrounding spins. We then consider perfect state transfer through a spin chain in the presence of decoherence and discuss the dependence of the transfer quality on spatial noise correlation length. We identify qualitatively different features for dephasing and dissipative environments in spin-transfer problems.

water blooming

description: Algal blooms are a frequent phenomenon in nearly all kinds of fresh water. They appear as a consequence of a rapid and excessive increase of the algal population in the aquatic environment. Global warming and eutrophication by wastewater, air pollution and fertilizers seem to lead to an increased frequency of occurrence. In many cases, these blooms are caused by Cyanobacteria (blue-green algae), which are believed to be some of the oldest organisms on Earth with fossil records dating back 3.5 billion years. This long period of evolution has enabled cyanobacteria to produce a vast array of biologically active metabolites, some of which are hazardous and quite persistent toxins (cyanotoxins), able to contaminate the respective water bodies. Under special conditions, especially when nutrient-rich waters are exposed to light, cyanobacteria can show a significantly accelerated rate of reproduction, resulting in a sudden increase in total biomass known as water blooming.

description: Synthetic lipid membranes in the absence of proteins can display quantized conduction events for ions that are virtually indistinguishable from those of protein channel. By indistinguishable we mean that one cannot decide based on the current trace alone whether conductance events originate from a membrane, which does or does not contain channel proteins. Additional evidence is required to distinguish between the two cases, and it is not always certain that such evidence can be provided. The phenomenological similarities are striking and span a wide range of phenomena: The typical conductances are of equal order and both lifetime distributions and current histograms are similar. One finds conduction bursts, flickering, and multistep-conductance. Lipid channels can be gated by voltage, and can be blocked by drugs. They respond to changes in lateral membrane tension and temperature. Thus, they behave like voltage-gated, temperature-gated and mechano-sensitive protein channels, or like receptors. Lipid channels are remarkably under-appreciated. However, the similarity between lipid and protein channels poses an eminent problem for the interpretation of protein channel data. For instance, the Hodgkin-Huxley theory for nerve pulse conduction requires a selective mechanism for the conduction of sodium and potassium ions. To this end, the lipid membrane must act both as a capacitor and as an insulator. Non-selective ion conductance by mechanisms other than the gated protein-channels challenges the proposed mechanism for pulse propagation. ... Some important questions arise: Are lipid and protein channels similar due a common mechanism, or are these similarities fortuitous? Is it possible that both phenomena are different aspects of the same phenomenon? Are lipid and protein channels different at all? ... (abbreviated)

description: The fungal metabolite TAN-2483B has a 2,6-trans-relationship across the pyran ring of its furo[3,4-b]pyran-5-one core, which has thwarted previous attempts at its synthesis. We have now developed a chiral pool approach to this core and prepared side-chain analogues of TAN-2483B. The synthesis relies on ring expansion of a reactive furan ring-fused dibromocyclopropane and alkynylation of the resulting pyran. The furan ring is constructed by palladium-catalysed carbonylative lactonisation. Various side-chains are appended through Wittig-type chemistry. The prepared analogues showed micromolar activity towards cancer cell lines HL-60, 1A9 and MCF-7 and certain human disease-relevant kinases, including Bruton's tyrosine kinase (Btk).
Female Transcendence: Charles Howard Hinton and Hyperspace Fiction
Creators: name: Beesley (Newcastle University), Patricia
Publisher: name: Victorian Network
Year: 2016

description: As far as nineteenth-century mathematician and writer Charles Howard Hinton was concerned, it was an unwillingness to explore beyond the boundaries of established epistemologies that prevented the conception of a fourth dimension or hyperspace. In this essay, I consider how Hinton employs the allegory of hyperspace to re-imagine women as transcendent. In the novellas, Stella and An Unfinished Communication (1895), he disavows not only a scientific epistemology that prevents a more expansive world view but also a gender ideology that constrains ideas of femininity. I argue that Hinton's radical re-imagining of the nature of the world, human consciousness and femininity leads him to create women who transcend a Victorian ideology that has defined them by their biology and the Hegelian sense of immanence in order to achieve higher consciousness. I draw comparisons between Hinton and New Woman novelists, who were writing at the same time, suggesting that both were engaged in re-imagining ideas of femininity and the kind of world women might occupy. But where nineteenth-century New Woman novelists anticipated individual transformation through a process of social and political change, Hinton envisaged social change as depending on an introspective, internal process of transcendence.

description: Tissue engineering implies the use of a combination of different cell types, methods, and suitable biochemical and physicochemical factors for making functional tissue outside of the body. Certain types of cells and tissue are being collected on so-called scaffolds with serum in an environment that encourages their growth. Tissue engineering is a relatively new scientific topic that is implemented in two very hot topics today – regenerative medicine and cultivated meat production. Namely, one of the main focuses of tissue engineering involves organ regeneration, which can subsequently be used as a donor organ or even miniaturized to test drugs for toxicity, in the case of drug screening within the liver. Clinical applications also involve growing skin for burn victims or organs for patients requiring organ transplantation. On the other hand, there is cultivated meat production – a consequence of the rate of demand we can’t presently sustain with animal-based food production.

‘The Apotheosis of Voice’: Mesmerism as Mechanisation in George Du Maurier’s Trilby“
Creators: name: Schlauraff (Cornell University), Kristie A.
Publisher: name: Victorian Network
Year: 2016

description: This article considers the relationship between mesmeric and sonic influence in George Du Maurier's Trilby “to argue that mesmerism offered a significant framework for conceptualising sound in the late-Victorian era. Drawing on Franz Anton Mesmer's theorisation of a ‘universally distributed and continuous fluid' affecting all animate and inanimate bodies, I demonstrate how sound similarly constructs networks of influence that facilitate communication but privilege certain individuals over others. Published in 1894, when mesmerism was firmly categorised as unscientific, but set in the 1850s when its legitimacy remained contested, Trilby “exposes the shift from mesmerism as aspiring science to mesmerism as metaphor. Through a comparison of scenes of looking and listening in the novel, I argue that sound facilitates communication between bodies more readily than sight. While looking is depicted as an individualised process that reinforces the separateness of bodies, listening is represented as a collective endeavour that exposes the interconnectedness of the audience members. Trilby's vocalisations facilitate a mode of shared experience previously deemed impossible, yet her figuration as a ‘singing-machine' leaves her isolated. Aligning the mesmeric subject with the mechanised human, Du Maurier's work reveals the relationship between mesmeric and sonic influence to depict sound's most threatening implications.

Two Brains and a Tree: Defining the Material Bases for Delusion and Reality in the Woodlanders
Creators: name: West (University Of St Andrews, UK), Anna

Year: 2016

description: In The Woodlanders “(1887), Thomas Hardy engages with contemporary scientific and philosophical discourse in his depiction of Edred Fitzpiers and the two brains he seeks to study: the brains of Grammer Oliver and John South, the latter who has just died from fear of a tree. While the character of Fitzpiers reflects some of the fears that physiologists raised for the Victorian public, Hardy continually creates a series of doublings to both illuminate the scientific discussion and complicate it. Following the movement away from the metaphysical toward the material causes underlying all action and feeling, Hardy subtly suggests the physical basis for John South's delusions; furthermore, he blurs clear delineations between illusion and reality. At the same time as suggesting that man might be no more than a machine, his fiction calls for empathy with even the inanimate world-without which, he seems to argue, there can be no fellow-feeling for humankind. While his contemporaries were asking whether vivisecting an animal was like vivisecting a human, Hardy moves the question one step further, dislimning boundaries between the arboreal and the human: as can be seen in the following investigation of two brains and a tree.

description: Radio observations prove the existence of relativistic particles and magnetic field associated with the intra-cluster-medium (ICM) through the presence of extended synchrotron emission in the form of radio halos and peripheral relics. This observational evidence has fundamental implications on the physics of the ICM. Non-thermal components in galaxy clusters are indeed unique probes of very energetic processes operating within clusters that drain gravitational and electromagnetic energy into cosmic rays and magnetic fields. These components strongly affect the (micro-)physical properties of the ICM, including viscosity and electrical conductivities, and have also potential consequences on the evolution of clusters themselves. The nature and properties of cosmic rays in galaxy clusters, including the origin of the observed radio emission on cluster-scales, have triggered an active theoretical debate in the last decade. Only recently we can start addressing some of the most important questions in this field, thanks to recent observational advances, both in the radio and at high energies. The properties of cosmic rays and of cluster non-thermal emissions depend on the dynamical state of the ICM, the efficiency of particle acceleration mechanisms in the ICM and on the dynamics of these cosmic rays. In this review we discuss in some detail the acceleration and transport of cosmic rays in galaxy clusters and the most relevant observational milestones that have provided important steps on our understanding of this physics. Finally, looking forward to the possibilities from new generations of observational tools, we focus on what appear to be the most important prospects for the near future from radio and high-energy observations.

description: Stochastic frontier models along the lines of Aigner et al. are widely used to benchmark firms’ performances in terms of efficiency. The models are typically fully parametric, with functional form specifications for the frontier as well as both the noise and the inefficiency processes. Studies such as Kumbhakar et al. have attempted to relax some of the restrictions in parametric models, but so far all such approaches are limited to a univariate response variable. Some (e.g., Simar and Zelenyuk; Kuosmanen and Johnson) have proposed nonparametric estimation of directional distance functions to handle multiple inputs and outputs, raising issues of endogeneity that are either ignored or addressed by imposing restrictive and implausible assumptions. This article extends nonparametric methods developed by Simar et al. and Hafner et al. to allow multiple inputs and outputs in an almost fully nonparametric framework while avoiding endogeneity problems. We discuss properties of the resulting estimators, and examine their finite-sample performance through Monte Carlo experiments. Practical implementation of the method is illustrated using data on U.S. commercial banks.
Lucid Daydreaming: Experience and Pathology in Charlotte Brontà«
Creators: name: Gao (University Of Oxford), Timothy
Publisher: name: Victorian Network
Year: 2016

description: This paper examines representations of daydreaming in the correspondence, journals, and novels of Charlotte Brontà« as a case study for the often hidden conflict between medical histories and first-person accounts of mental states. While the emerging field of nineteenth-century psychology diagnosed daydreaming as an intense and involuntary state of consciousness analogous to trances, sleep states, opiates, and mental illnesses, accounts by daydreamers themselves represented their daydreams as critical, rational, and conscious alternatives to dissatisfactions in their social and economic realities. By foregrounding this latter perspective in Brontà«'s letters and in Shirley“, I argue for a re-evaluation of the relationship between the disciplinary authority of medical science and the historical individual's experience of their own mind, and for a more optimistic view of volition and autonomy, both in studies of Brontà« and in medical humanities research more generally. This more hopeful reading of the literary and historical record enabled by an investigation of the common daydream also suggests the methodological value of shifting away from our existing focus on mental disorder and abnormality towards the significance of healthy, everyday, yet historically significant modes of consciousness.

description: Polar molecules are desirable systems for quantum simulations and cold chemistry. Molecular ions are easily trapped, but a bias electric field applied to polarize them tends to accelerate them out of the trap. We present a general solution to this issue by rotating the bias field slowly enough for the molecular polarization axis to follow but rapidly enough for the ions to stay trapped. We demonstrate Ramsey spectroscopy between Stark-Zeeman sublevels in 180Hf19F+ with a coherence time of 100 ms. Frequency shifts arising from well-controlled topological (Berry) phases are used to determine magnetic g-factors. The rotating-bias-field technique may enable using trapped polar molecules for precision measurement and quantum information science, including the search for an electron electric dipole moment.

description: We consider the possible production of the Higgs Boson in association with a top-quark pair and its subsequent decay into a tau-lepton pair or a W-boson pair. This process can give rise to many signatures of the Higgs boson. These signatures can have electrons, muons, tau jets, bottom jets and/or light flavour jets. We analyze the viability of some of these signatures. We will look at those signatures where the background is minimal. In particular, we explore the viability of the signatures "isolated 4 electron/muon" and "isolated 3 electron/muon + a jet" The jet can be due to a light flavour quark/gluon, a bottom quark, or a tau lepton. Of all these signatures, we find that "isolated 3 electron/muon + a tau jet", with an extra bottom jet, can be an excellent signature of this mode of the Higgs boson production. We show that this signature may be visible within a year, once the Large Hadron Collider (LHC) restarts. Some of the other signatures would also be observable after the LHC accumulates sufficient luminosity.

description: To successfully meet the demands of the social environment, individuals must adaptively respond to social stressors. Early life stress (ELS) and loneliness are two types of social stressors associated with a variety of adverse psychological and physiological outcomes in adulthood. Empathy also plays an influential role in the social environment by fostering the formation and maintenance of interpersonal relationships. While prior research explores the relationships between ELS and loneliness and/or empathy and loneliness, the interactions between these variables have not been well established. The current study investigates the interactions between social stressors (i.e., ELS, loneliness) and empathy, in addition to their associations with two measures of autonomic nervous system (ANS) reactivity: heart rate (HR) reactivity and high- frequency heart rate variability (HF-HRV) reactivity. Participants (N = 119) completed a series of questionnaires to assess ELS, loneliness, and empathy, and a subset of participants (n = 41) underwent a social stress manipulation to assess physiological reactivity to an acute social stressor. Consistent with prior research, higher levels of ELS predicted higher levels of loneliness. Furthermore, emotional abuse (EA) interacted with cognitive empathy to predict loneliness in adulthood, such that at higher levels of EA, lower levels of cognitive empathy corresponded to increased loneliness. The study also revealed that sexual abuse (SA) and physical abuse (PA) were positively associated with HF-HRV reactivity, and cognitive empathy was positively associated with HR reactivity. Conversely, loneliness showed a significant negative association with HF- HRV reactivity. These findings elucidate the relationships between social stressors, empathy, and physiological stress reactivity, and provide broader insight into how individuals respond to stressors in the social environment.

description: Some improved estimators are proposed for estimating the population mean in stratified sampling in the presence of auxiliary information. Mean square error (MSE) of the proposed estimators have been derived under large sample approximation. It has been shown that under optimum conditions proposed estimators are better than usual unbiased estimator and Hansen (1946) estimator. Both theoretical and empirical findings are encouraging and support the soundness of the proposed procedure for mean estimation.

description: A simple systematic procedure to construct the proton-neutron unitary, $u_{\text{sd}}^{πν}{(12)}$, orthogonal, $o_{\text{sd}}^{πν}{(12)}$, and quasi-spin $\text{su}_{\text{sd}}^{πν}{(1,1)}$ algebras of the sd bosonic system is presented. New algebraic substructures of these algebras are discussed and the explicit formulae for their generators and Casimir operators are given in the spherical tensor form. The complementarity relationship of the Casimir operators of the $\text{su}_{\text{sd}}^{πν}{(1,1)}$ and $o_{\text{sd}}^{πν}{(12)}$ is derived. The exact algebraic solutions of the quantum phase transition Hamiltonian between the $o_{\text{sd}}^{πν}{(12)}$ and $u_s^{πν}{(2)} \otimes u_d^{πν}{(10)}$ limits has been considered, for the first time, in the framework of affine $\text{su}_{\text{sd}}^{πν}{(1,1)}$ Lie algebra. The low lying energy spectra of the $\, ^{70}\text{Ge},\, ^{76-78}\text{Se},\, ^{96-98}\text{Mo},\text{and}\, ^{100-102}\text{Ru}$ isotopes are calculated using the $o_{\text{sd}}^{πν} {(12)} {\leftrightarrow} u_s^{πν}{(2)} \otimes u_d^{πν}{(10)}$ transition Hamiltonian. The good agreement of our computation with empirical result in these isotopes emphasizes the importance of $u_s^{πν}{(2)} \otimes u_d^{πν}{(10)}$ limit. With this addition, symmetry can be extended to many nuclei.

description: The surroundings of Luminous Blue Variable (LBV) stars are excellent laboratories to study the effects of their high UV radiation, powerful winds, and strong ejection events onto the surrounding gas and dust. The LBV G79.29+0.46 powered two concentric infrared rings which may interact with the infrared dark cloud (IRDC) G79.3+0.3. The Effelsberg 100m telescope was used to observe the NH_3 (1,1), (2,2) emission surrounding G79.29+0.46 and the IRDC. In addition, we observed particular positions in the (3,3) transition toward the strongest region of the IRDC. We report here the first coherent shell-like structure of dense NH_3 gas associated with an evolved massive star. The shell, two or three orders of magnitude more tenuous than the IRDC, is well traced in both ammonia lines, and surrounds the ionized nebula. The NH_3 emission in the IRDC is characterized by a low and uniform rotational temperature (T_rot ~ 10 K) and moderately high opacities in the (1,1) line. The rest of the observed field is spotted by warm or hot zones (T_rot > 30 K) and characterized by optically thin emission of the (1,1) line. The NH_3 abundances are about 10^{-8} in the IRDC, and 10^{-10}-10^{-9} elsewhere. The warm temperatures and low abundances of NH_3 in the shell suggest that the gas is being heated and photo-dissociated by the intense UV field of the LBV star. An outstanding region is found to the south-west (SW) of the LBV star within the IRDC. The NH_3 (3,3) emission at the centre of the SW region reveals two velocity components tracing gas at temperatures > 30K. The northern edge of the SW region agrees with the border of the ring nebula and a region of continuum enhancement; here, the opacity of the (1,1) line and the NH_3 abundance do not decrease as expected in a typical clump of an isolated cold dark cloud. This strongly suggests some kind of interaction between the ring nebula and the IRDC.

Figure 20
TYPE MATERIAL.— Holotype (Figs.20A–B), a male, in CAS, labeled: “ MADAGASCAR, Ranomafana NP., montane rainforest near Tsinjorano village, 100 m in from forest edge,”/ “ 21.09637°S 47.52085°E, 1050 m, 19.05.2005, collected by hand in daytime, F.J. Ratelolahy collector”/ “ HOLOTYPE Madecassina quadrimaculata Kavanaugh & Rainio sp. n. 2015” [red label].
TYPE LOCALITY.— Madagascar, Fianarantsoa Province, Ranomafana National Park.
DERIVATION OF SPECIES NAME.— The species epithet, quadrimaculata, is an adjective derived from the Latin words, quattuor, meaning four, and macula, meaning spot or spotted. The name refers to the two (subbasal and subapical) pairs of elytral spots seen in members of this species.
RECOGNITION.— Size average for genus, SBL = 5.2 mm. The holotype male of this species (Fig. 20A) keys to Madecassina maculata Alluaud (1899b) in Jeannel’s (1949) key based on the following combination of features: body black, forebody without metallic reflection, pronotum punctate laterally, and elytra shiny with four pale spots. It differs from members of M. maculata in having a smaller body size (SBL = 5.5–6.0 mm in M. maculata), the pronotum punctate laterally and laterobasally only, with conspicuous transverse grooves and ridges on disc (in M. maculata the pronotum is punctate on the disc also, between the ridges, in contrast to what Jeannel said in his key), elytral intervals shinier due to more shallowly impressed isodiametric microsculpture (elytral intervals duller due to more deeply impressed isodiametric microsculpture in M. maculata), the elytral spots much more distinct (much less so in M. maculata) and median lobe of male genitalia with apex hooked dorsally and thicker in lateral aspect (Fig. 20C) and slightly swollen and bent right in dorsal aspect (Fig. 20D) (apex hooked but thinner in lateral aspect and more parallel-sided and straight in dorsal aspect in M. maculata males) (see Jeannel 1949, Fig. 474f).
GEOGRAPHICAL DISTRIBUTION.— At present, known only from the type locality.
HABITAT DISTRIBUTION.— The unique holotype was collected in montane rainforest near Tsinjorano village at a distance of 100 m inside the forest edge at an elevation of 1050 m.

Neo-Victorian Dirt and Decomposition
Creators: name: Kirkby (King’s College London), Nicola
Publisher: name: Victorian Network
Year: 2015

description: In neo-Victorian writing, which blurs boundaries between the past and present, dirt is extremely mobile. Through close analysis of dirt-evoking encounters in Michel Faber’s works The Crimson Petal and the White (2002), and The Apple (2006); Adam Roberts’s novel Swiftly (2004); and Iain Sinclair’s White Chappell, Scarlet Tracings (1987), this article explores the link dirt provides between Victorian sensory experience and modern imaginings of the period. Unclean matter does more than simply add authenticating grime to literary recreations of the Victorian past. Commencing with bodily dirt, this article reveals unresolved ethical ambiguities raised in these four provocative works. These works humanise neo-Victorian characters but depict bodily processes in graphic, exposing detail. Non-bodily dirt, meanwhile, has remarkable freedom to move in these texts but becomes implicated in the universal movement of all material towards a state of entropy. Neo-Victorian fiction bridges past and present experience without downplaying material differences that distinguish Victorian life from our own. This article examines how neo-Victorian fiction self-consciously employ dirt as a means of articulating problems raised by creatively engaging with a past age, while also shedding light on how fictionalisation might help us understand Victorian dirt.

Bad Property: Unclean Houses in Victorian City Writing
Creators: name: Kvistad (University Of Oslo), Erika
Publisher: name: Victorian Network
Year: 2015

description: This essay considers dirt as a source of horror in late nineteenth-century urban exploration writing, in which middle-class writers explore the homes of poor city dwellers. I argue that for these writers, dirt was the point where scientifically driven social activism and superstitious horror met. They imagined poor homes as “bad propertyâ€, both the location and the source of moral uncleanness. The by then disproved miasma theory of disease persists in these texts both as a fact and as a persuasive metaphor. It allowed urban exploration writers to articulate both the fear of the squalid dwellings where poverty, disease and moral decay arise, and the fear that this badness might spread through the wealthier parts of the city. In this way, the demolition of filthy homes functioned not only as a social project, but as a form of exorcism. But three other central works of late-Victorian city writing, Margaret Oliphant's A Beleaguered City“, W.T. Stead's ‘The Maiden Tribute of Modern Babylon’ and R.L. Stevenson's Strange Case of Dr Jekyll and Mr Hyde“, use the idea of the unclean house for new purposes, undermining the equivalence between cleaning up the city and eradicating its horror. The concept of “bad propertyâ€ becomes, instead, a way of locating horror close to home, at the heart of respectable middle-class houses.

Eco-Conscious Synaesthesia: Dirt in Kennedy’s Yeast“ and Alton Locke“
Creators: name: Kennedy (State University Of New York, Stony Brook), Margaret S.
Publisher: name: Victorian Network
Year: 2015

description: Miasmic language in Charles Kingsley's novels Yeast“ and Alton Locke“ imaginatively renders unseen dirt visible through synaesthesia. I suggest that Kingsley is engaging in discursive activism through consistent suggestion of the concept of miasma in these works in order to increase public anxiety about pollution. This linguistic strategy was designed to incite real action through a provocation toward what I call ‘eco-consciousness’ in his readers. Miasmic language gets under the skin, opening readers' eyes to anthropogenic pollution and their concomitant vulnerability to contagion. Kingsley sensationalises toxicity to uncover the environmental horrors in domestic spaces. Miasma startles fictional characters, who “see and “feelâ€ smell, as the reader ought to be startled by miasmic language designed to stimulate or overwhelm the senses. Kingsley's fictional authors, Locke and Smith, frequently employ words from the miasmic lexicon – i.e., 'foul', 'reeking', and 'stagnant' – to describe the filth engulfing England. Though these words connote vapours, or miasmata, Kingsley broadens the concept of foul dampness from organic matter to man-made dangers, such as industrial fumes and waste particles. Yeast“, set in the rural South, and Alton Locke“, set in urban London, offer a complete picture of filth, revealing widespread environmental injustice.

description: In bouncing cosmology, the primordial fluctuations are generated in a cosmic contraction phase before the bounce into the current expansion phase. For a nonsingular bounce, curvature and anisotropy grow rapidly during the bouncing phase, raising questions about the reliability of perturbative analysis. In this paper, we study the evolution of adiabatic perturbations in a nonsingular bounce by nonperturbative methods including numerical simulations of the nonsingular bounce and the covariant formalism for calculating nonlinear perturbations. We show that the bounce is disrupted in regions of the universe with significant inhomogeneity and anisotropy over the background energy density, but is achieved in regions that are relatively homogeneous and isotropic. Sufficiently small perturbations, consistent with observational constraints, can pass through the nonsingular bounce with negligible alteration from nonlinearity. We follow scale invariant perturbations generated in a matter-like contraction phase through the bounce. Their amplitude in the expansion phase is determined by the growing mode in the contraction phase, and the scale invariance is well preserved across the bounce.
