 Type material: Holotype: BELUM Mc 7627. Sample in 95% ethanol, tissue section and spicule preparation on slides; Right Whale Bay, South Georgia (54°00.173’S, 37° 40.856’W); depth 18m; collected by C. Goodwin, J. Brown and S. Brown, 21 st November 2010.
 Paratype: BELUM Mc 7677. Sample in 95% ethanol, tissue section and spicule preparation on slides; Green Island, Stromness, Site 1, South Georgia (54°09.448’S, 36° 39.752’W); depth 17.4m; collected by C. Goodwin, P. Brickle and S. Cartwright, 27 th November 2010.
 Etymology: Named after Dr David Barnes of British Antarctic Survey, project leader of the ‘Mapping the Benthic Biodiversity of South Georgia’ Darwin Initiative, in recognition of his support of this work.
 External morphology: In situ appearance: Thinly encrusting (<3mm), bright orange, crust with pore sieves. Star shaped patterns of exhalent channels also visible (Fig. 10a). Encrusting on bedrock, patches up to 15cm in diameter.
 Preserved appearance: Thin white crust.
 Skeleton: Typical hymedesmoiid skeleton with a dense basal layer of primary and echinating acanthostyles with ascending columns of the ectosomal spicules 3–6 spicules thick. Thick ectosomal layer of chelae (Fig. 10b).
 Spicules: Measurements from Mc7627.
 Primary acanthostyles: 272(317)392 by 22(29)39µm at head. Tylote head bearing short rounded spines. Spined up to 1/3 of the shaft (Fig. 10c).
 Echinating acanthostyles: 102(138)161 by 9.3(17.2)24.5µm at head. Entirely spined with conical pointed spines (Fig. 10d).
 Ectosomal spicules: styles/tornotes 188(249)276 by 5.1(6.8)9.5µm. Fusiform with the ends variable in form: the majority are styles with one rounded, sometimes slightly tylote, and one pointed end but in some spicules the rounded end is modified into a point (Fig. 10e,f).
 Chelae: 23.6(27.7)30.7µm (Fig. 10g).
 Remarks: The majority of Hymedesmia (Hymedesmia) species occurring in the Antarctic have much bigger spicules or they possess sigma microscleres (Table 5). The size range of the spicules in this species is similar to H. gaussiana Hentschel, 1914. Unfortunately the type specimen of this species (ZMH collection) was destroyed in the Second World War and so is not available for examination. However, it differs in having strongyles as ectosomal spicules and entirely spined large acanthostyles.

description: We develop a modified version of the totally asymmetric simple exclusion process (TASEP) and use it to reproduce flow on an escalator with two distinct lanes of pedestrian traffic. The model is used to compare strategies with two standing lanes and a standing lane with a walking lane, using theoretical analysis and numerical simulations. The results show that two standing lanes are better for smoother overall transportation, while a mixture of standing and walking is advantageous only in limited cases that have a small number of pedestrians. In contrast, with many pedestrians, the individual travel time of the first several entering particles is always shorter with distinct standing and walking lanes than it is with two standing lanes.

description: The transition from dimerized to uniform phases is studied in terms of spectral weights for spin chains using continuous unitary transformations (CUTs). The spectral weights in the S=1 channel are computed perturbatively around the limit of strong dimerization. We find that the spectral weight is concentrated mainly in the subspaces with a small number of elementary triplets (triplons), even for vanishing dimerization. So, besides spinons, triplons may be used as elementary excitations in spin chains. We conclude that there is no necessity to use fractional excitations in low-dimensional, undoped or doped quantum antiferromagnets.

description: The precipitation of a glass forming solute from solution is modelled using a lattice model previously introduced to study dissolution kinetics of amorphous materials. The model includes the enhancement of kinetics at the surface of a glass in contact with a plasticizing solvent. We demonstrate that precipitation can produce a glass substantially more stable than that produced by very long time annealing of the bulk glass former. The energy of these ultra-stable amorphous precipitates is found to be dominated by residual solvent rather than high energy glass configurations.

description: The objective of this study is estimating carbon emissions in the building and transportation sectors in the Sumida ward, Tokyo. We combine top-down and bottom-up approaches, which use spatial big data, for the estimating. The estimated emissions from individual buildings and road links are visualized by a three-dimensional (3D) mapping. The results suggest the usefulness of our approach for visualizing urban carbon emissions for supporting community-level carbon monitoring and management.

description: Citizens and Emergency Managers need to be able to distinguish ''fake'' (untrue) news posts from real news posts on social media during disasters. This paper is based on an online survey conducted in 2018 that produced 341 responses from invitations distributed via email and through Facebook. It explores to what extent and how citizens generally assess whether postings are ''true'' or ''fake,'' and describes indicators of the trustworthiness of content that users would like. The mean response on a semantic differential scale measuring how frequently users attempt to verify the news trustworthiness (a scale from 1-never to 5-always) was 3.37. The most frequent message characteristics citizens' use are grammar and the trustworthiness of the sender. Most respondents would find an indicator of trustworthiness helpful, with the most popular choice being a colored graphic. Limitations and implications for assessments of trustworthiness during disasters are discussed.

description: The integration of Agent-Based Modelling (ABM) and Machine Learning (ML) provides many promising opportunities, yet this research field is underdeveloped. Different reasons are given for this lack of integration, including a shortage of behavioural data and technical implementation difficulties. However, we think that one crucial problem is being overlooked. In our educational system, we teach topics one by one and do not explicitly focus on the integration of various modelling paradigms. This is a missed opportunity that should be addressed, to prepare our students for a world where models are increasingly complex and where data and model integration becomes inevitable. In this paper, we share our experiences in a course in Geoinformatics, where integrated ABM and ML modelling is central. In our class, we use the Living Textbook to work on interlinked concept maps, and we have an overarching case study assignment. Preliminary outcomes show that students’ learning and project work could benefit from simplifying the case study assignment and introducing the parallel teaching of ABM and ML. In general, different teaching methods and setups still need to be explored, to ensure that our future model designers are well equipped for their task.

description: We report a detailed study, using neutron scattering, transport and magnetization measurements, of the interplay between superconducting (SC) and spin density wave (SDW) order in La2CuO(4+y). Both kinds of order set in below the same critical temperature. However, the SDW order grows with applied magnetic field, whereas SC order is suppressed. Most importantly, the field dependence of the SDW Bragg peak intensity has a cusp at zero field, as predicted by a recent theory of competing SDW and SC order. This leads us to conclude that there is a repulsive coupling between the two order parameters. The question of whether the two kinds of order coexist or microscopically phase separate is discussed.

description: This study assesses the reported farm income crisis in Canada and uses farm financial data to illustrate the importance and impact that management skills and practices have on farm income and net worth. For grain and oilseed farms, large farms produce higher revenues per hectare and achieve economies of scale on operating expenses, interest and depreciation, making them significantly more profitable than smaller or average sized farms. The higher profits associated with large farms are partly returns to good farm management. While farmland investment returns are competitive with stock and bond markets, grain and oilseed farm labour and management returns are not competitive with provincial average wages and salaries. On average, Canadian grain and oilseed farm families have less disposable income to spend today but have considerably more wealth than their non-farm family neighbours. The higher wealth level for farm families makes it increasingly difficult for governments to acknowledge a farm crisis and increase farm subsidies.

A propagator method is used to investigate the time evolution of 2D interference patterns after (i)only the optical lattice is swithed off, and (ii)both the optical lattice and the magnetic trap are swithed off. An analytical description on the motion of side peaks in the interference patterns is presented by using the density distribution in a momentum space.

description: Quantum information protocols often rely on tomographic techniques to determine the state of the system. A popular method of encoding information is on the different paths a photon may take, for example, parallel waveguides in integrated optics. However, reconstruction of states encoded onto a large number of paths is often prohibitively resource intensive and requires complicated experimental setups. Addressing this, we present a simple method for determining the state of a photon in a superposition of d paths using a rotating one-dimensional optical Fourier Transform. We establish the theory and experimentally demonstrate the technique by measuring a wide variety of six-dimensional density matrices. The average fidelity of these with the expected state is as high as 0.9852 +/- 0.0008. This performance is comparable or exceeds established tomographic methods for other types of systems.

description: Online social media platforms have made the world more connected than ever before, thereby making it easier for everyone to spread their content across a wide variety of audiences. Twitter is one such popular platform where people publish tweets to spread their messages to everyone. Twitter allows users to Retweet other users' tweets in order to broadcast it to their network. The more retweets a particular tweet gets, the faster it spreads. This creates incentives for people to obtain artificial growth in the reach of their tweets by using certain blackmarket services to gain inorganic appraisals for their content. In this paper, we attempt to detect such tweets that have been posted on these blackmarket services in order to gain artificially boosted retweets. We use a multitask learning framework to leverage soft parameter sharing between a classification and a regression based task on separate inputs. This allows us to effectively detect tweets that have been posted to these blackmarket services, achieving an F1-score of 0.89 when classifying tweets as blackmarket or genuine.

 Etymology: Named after Dr Judith Brown, Diving Officer for the expedition and her husband, Steve Brown, member of the expedition dive team.
 External morphology: In situ appearance: Yellow crust, up to 10mm thick. On the surface of the sponge the ectosomal spicule mesh is visible, giving a honeycomb appearance. Three specimens were growing over algae attached to bedrock. One specimen (Mc7621) is a thicker crust in which the surface has developed into a series of small lumps (Fig. 17a).
 Preserved appearance: Fragile white specimen which breaks easily into strands formed by the columns of the choanosomal skeleton. The ectosomal layer is more solid and glassily smooth.
 Skeleton: The choanosomal skeleton is formed of thick (up to 15 spicules wide) ascending columns of mycalostyles which divide towards the ectosome in a dendritic pattern. The ectosome is a tangential confused layer of mycalostyles. Chelae present throughout skeleton, the larger category are in rosettes (Fig. 17b).
 Spicules: Measurements from Mc7588.
 Mycalostyles: 448(601)537 by 11.4(15.6)20.3µm base with an oval tylote, other end coming to a rounded point (Fig. 17c).
 Anisochelae: two categories 30.5(44.4)52.6 and 67.2(81.7)88.0µm (Fig. 17d, e).
 Remarks: This species can be distinguished from most species the subgenus Mycale (Mycale) by its smaller mycalostyle size or the categories of microscleres, which are present (Table 9). It has a similar size range of mycalostyles to M. doellojuradoi Burton, 1940 but this has three categories of chelae, the smallest being 18µm. Descriptions of other species in the genus were examined in case of taxonomic confusions; these could be distinguished by differences in the size of mycalostyles or the categories of microscleres present.

description: Farm planning often focuses on optimal diversification with respect to risk, where the risk-management strategies combine production, marketing, financial and environmental aspects of the farm-firm. In this study an empirical examination of diversification has been carried out using a sample of farms in Eastern Norway. Four measures of diversification (indices) were defined to record the risks in relation to income from farm production. Using these alternative measures of diversification and panel-data, the results show that larger farms are more diversified, and for farms in more favourable locations and access to labour, the farmers have a greater incentive to spread risk. These results suggest that diversification and farm size are positively linked and that there may not be sufficient economies of scale to warrant specialisation and/or farm specialisation may not be environmentally desirable because of the pollution that would result. The Norwegian model offers good prospects for analysing similar issues of diversification in the Australian farming sector.

description: Spatio-temporal networks are a useful tool for examining systems such as transport networks. However, it is relatively difficult to examine continuous temporal change in the properties of network connections. Spatially correlated time series analysis often uses only distance to estimate correlations between time series, which is not necessarily applicable to a network system.Longitudinal data analysis methods that are common in epidemiology and psychology may be combined with spatio-temporal network data to capture complex temporal patterns at the level of individual observation-units, for example individual network objects. These can be used to distil complex temporal information into specific easily interpretable variables that represent a specific part, or feature, of a temporal pattern, such as the timing of maxima.This paper illustrates how these methods could be combined with geographical methods to generate meaningful and interpretable results describing spatial variation in temporal patterns of temperature in a rail network. Longitudinal methods considered were: multilevel modelling and functional data analysis.Results show differences across the longitudinal methods used that are likely down to necessary differences in model specification. The appropriate parameterisation of each method is one of several factors that will affect the utility of these methods to accurately capture temporal pattern features in a meaningful way. There is considerable scope for further investigation of the utility of these methods through simulation.
2d duality for orthogonal gauge theories with 8 supersymmetries

description: We recently conjectured a set of dualities relating two-dimensional orthogonal gauge theories with $\mathcal{N}=(4,4)$ supersymmetry, analogous to Hori's dualities with $\mathcal{N}=(2,2)$ supersymmetry. Here we provide a quantitative test of this conjecture by computing the elliptic genera of the dual pairs and showing that they agree. The elliptic genus of orthogonal gauge theories has multiple topological sectors that depend on the global structure of the group and on the value of a discrete $θ$ parameter. We derive the dependence on the $θ$ parameter by determining whether a given sector has $(S)Pin$ structure or not.

description: In this paper, we have recognized that the relatively constant inequality in the distribution of U.S. family income masks dramatic changes in the structure of the income distribution and the composition of personal incomes. Using relatively new procedures for decomposing the Gini measure of income inequality, we have gained a better understanding of the relationships among changes in the sources of income and the income distribution. This is facilitated through the use of data collected by the Census Bureau in the Survey of Income and Program Participation, which is the only set of data currently available that contains exhaustive lists of income and asset information at the household level. The empirical results are used in conjunction with data on transfer program expenditures to gain some perspective on the relative costs of reducing income inequality by increasing program benefits.

description: We develop an interpolating self-energy approach to the correlated Kondo-lattice model. The correlation of the band electrons is taken into account by a Hubbard interaction. The method is based on a self-energy ansatz, the structure of which allows to fulfill a maximum number of exactly solvable limiting cases. The parameters of the ansatz are fitted to spectral moments via high-energy expansion of the self-energy. The band electron correlations are taken into account by an effective medium approach being correct in the strong coupling (U) regime. The theory is considered reliable for all temperatures, band occupations, and exchange couplings. Results are presented for the respective dependencies of spectral densities, quasiparticle densities of states, and characteristic correlation functions, and interpreted in terms of elementary spin exchange processes between itinerant conduction electrons and localized magnetic moments. The appearance of magnetic polarons, the typical quasiparticle of Kondo-lattices, in the energy spectrum is worked out. Spin exchange processes prevent a total spin polarization of the band electrons even for arbitrarily strong exchange couplings as long as the local moments are represented by quantum mechanical spins.

description: Space, location, coordinates, distance: these interrelated concepts and their practical realisations in data structures, analytical procedures, and visualization techniques arecentral to what computation is able to achieve in geographical research. We argue the ideals and approaches of GeoComputation have much to contribute to the realisation of a geographical computation that embraces not only the representation and analysis of phenomena in absolute, Euclidean space, but can engage relative and relational spaces as well. Such spaces emerge with process and relation, and they were viewed as central toadvancing geographical research during the quantitative revolution. We present results of initial steps taken in this geocomputational research agenda: we formalise, implement, exemplify, and analyse a generalized, empirical projection approach appropriate to translating between the (sometimes complicated and emergent) coordinate systems of relational, relative, and absolute spaces.

description: We propose a novel hybrid platform where solid-state spin qubits are coupled to the acoustic modes of a two-dimensional array of optomechanical nano cavities. Previous studies of coupled optomechanical cavities have shown that in the presence of strong optical driving fields, the interplay between the photon-phonon interaction and their respective inter-cavity hopping allows the generation of topological phases of sound and light. In particular, the mechanical modes can enter a Chern insulator phase where the time-reversal symmetry is broken. In this context, we exploit the robust acoustic edge states as a chiral phononic waveguide and describe a state transfer protocol between spin qubits located in distant cavities. We analyze the performance of this protocol as a function of the relevant system parameters and show that a high-fidelity and purely unidirectional quantum state transfer can be implemented under experimentally realistic conditions. As a specific example, we discuss the implementation of such topological quantum networks in diamond based optomechanical crystals where point defects such as silicon-vacancy centers couple to the chiral acoustic channel via strain.

description: We have found an exact formula expressing a general correlation function containing both products and ratios of characteristic polynomials of random Hermitian matrices. The answer is given in the form of a determinant. An essential difference from the previously studied correlation functions (of products only) is the appearance of non-polynomial functions along with the orthogonal polynomials. These non-polynomial functions are the Cauchy transforms of the orthogonal polynomials. The result is valid for any ensemble of beta=2 symmetry class and generalizes recent asymptotic formulae obtained for GUE and its chiral counterpart by different methods..

description: Cellular Automata (CA) have formed an important part of the geocomputational and spatial analysis toolbox for three decades. Some of the most important components of CA are the transition rules to determine the changes in cell states across iterations. These are applied at the micro-sale, but lead to emergent patterns at the macro-scale. An important consideration for transition rules is the spatial extent over which they will be valid. One does not expect the same rules to apply equally across an entire region, yet most CA implementations only support one set of transition rules that are applied everywhere. In this paper, a vector CA model with spatially partitioned transition rules is proposed to identify the expansion of urban residential areas across heterogeneous study area. Initial experiments using two sub-regions of Ipswich, Queensland, Australia, indicate that the spatially partitioned approach can improve the accuracy of vector CA.

description: We employ a game engine – Unity – to create a rockfall simulation that integrates high resolution slope data from LiDAR scanning and photogrammetry, simulates hundreds of rocks moving on a slope, and provides outputs relevant to geological engineering decision support. This approach, in contrast to existing rockfall simulation tools that are specific to limited slope types, is general, extensible, and robust. The use of a game engine as a simulator for surface geological processes represents a novel approach to geocomputationthat leverages the physics simulation capability of games and the powerful terrain representation and visualization capabilities of 3D game engines.
Correlation studies of open and closed states fluctuations in an ion channel: Analysis of ion current through a large conductance locust potassium channel

description: Ion current fluctuations occurring within open and closed states of large conductance locust potassium channel (BK channel) were investigated for the existence of correlation. Both time series, extracted from the ion current signal, were studied by the autocorrelation function (AFA) and the detrended fluctuation analysis (DFA) methods. The persistent character of the short- and middle-range correlations of time series is shown by the slow decay of the autocorrelation function. The DFA exponent $α$ is significantly larger than 0.5. The existence of strongly-persistent long-range correlations was detected only for closed-states fluctuations, with $α=0.98\pm0.02$. The long-range correlation of the BK channel action is therefore determined by the character of closed states. The main outcome of this study is that the memory effect is present not only between successive conducting states of the channel but also independently within the open and closed states themselves. As the ion current fluctuations give information about the dynamics of the channel protein, our results point to the correlated character of the protein movement regardless whether the channel is in its open or closed state.

description: Recognizing named entities in a document is a key task in many NLP applications. Although current state-of-the-art approaches to this task reach a high performance on clean text (e.g. newswire genres), those algorithms dramatically degrade when they are moved to noisy environments such as social media domains. We present two systems that address the challenges of processing social media data using character-level phonetics and phonology, word embeddings, and Part-of-Speech tags as features. The first model is a multitask end-to-end Bidirectional Long Short-Term Memory (BLSTM)-Conditional Random Field (CRF) network whose output layer contains two CRF classifiers. The second model uses a multitask BLSTM network as feature extractor that transfers the learning to a CRF classifier for the final prediction. Our systems outperform the current F1 scores of the state of the art on the Workshop on Noisy User-generated Text 2017 dataset by 2.45% and 3.69%, establishing a more suitable approach for social media environments.

description: We construct Heisenberg anti-ferromagnetic models in arbitrary dimensions that have isotropic valence bond crystals (VBC) as their exact ground states. The d=2 model is the Shastry-Sutherland model. In the 3-d case we show that it is possible to have a lattice structure, analogous to that of SrCu_2(BO_3)_2, where the stronger bonds are associated with shorter bond lengths. A dimer mean field theory becomes exact at d -> infinity and a systematic 1/d expansion can be developed about it. We study the Neel-VBC transition at large d and find that the transition is first order in even but second order in odd dimensions.

 Ataenius brevis Fall 1930: 98. Lectotype: MCZ, here designated, sex unknown.
 Type material. Fall (1930) described Ataenius brevis from two specimens of undetermined sex from Pennsylvania collected by Henry Ulke. There are two specimens in the MCZ with typed and handwritten designation labels reading “ TYPE brevis” and “brevis PARATYPE Fall. 1930”. Fall gave no indication which specimen was the holotype and these designations may have been added later. We are here designating a specimen (Fig. 1–5) with the following data (Fig. 4) as the lectotype to fix the name to a single specimen: “Pen // Horn Coll / H // [underlined in red] TYPE / [handwritten] brevis // [on red] M. C. Z. / Type / [handwritten] 24767 // H. C. FALL / COLLECTION // Aug-Dec 2005 / MCZ Image / Database // MCZ-ENT / 00024767 // [on red] LECTOTYPE / Ataenius brevis Fall, 1930 / Designated by / Schnepp & Ashman, 2020”. The second specimen in the MCZ with the following data becomes a paralectotype: “Pen // [on red] [handwritten] brevis / PARATYPE / [handwritten] Fall. 1930 // Liebeck / Collection // MCZ-ENT / 00731922 // [on red] PARALECTOTYPE / Ataenius brevis Fall, 1930 / Designated by / Schnepp & Ashman, 2020”.
 Fall’s original description is adequate to define A. brevis, however, Cartwright (1974) gave a thorough redescription. Both syntypes match these descriptions, therefore no redescription is given here.
 Distribution. Ataenius brevis appears to be restricted to the Appalachian region of eastern North America (Fig. 13). Label data indicate specimens have been collected in the following situations: “Berlesed from leaf litter”, “Berlese forest floor”, “under leaves in path”, “under leaves”, “leaf litter”, “under log”, “on beach”, “Lindgren funnel trap”, and “in ice Jan. thaw”.
 Remarks. Specimens collected by month: January (1), March (4), April (9), May (55), June (69), July (59), August (28), September (5), October (3), November (1).

description: We investigate by time-resolved Synchrotron ultra-small X-ray scattering the dynamics of liquid-liquid phase-separation (LLPS) of gluten protein suspensions following a temperature quench. Samples at a fixed concentration (237 mg/ml) but with different protein compositions are investigated. In our experimental conditions, we show that fluid viscoelastic samples depleted in polymeric glutenin phase-separate following a spinodal decomposition process. We quantitatively probe the late stage coarsening that results from a competition between thermodynamics that speeds up the coarsening rate as the quench depth increases, and transport that slows downs the rate. For even deeper quenches, the even higher viscoelasticity of the continuous phase leads to a "quasi" arrested phase separation. Anomalous phase-separation dynamics is by contrast measured for a gel sample rich in glutenin, due to elastic constraints. This work illustrates the role of viscoelasticity in the dynamics of LLPS in protein dispersions.
