description: 13. Cheumatopsyche concava species group
Species in this group are characterised by having a unilobed segment X with apicoventral setal lobes almost completely fused with segment X (Fig. 13). All processes or lobes on segment X are fused, except for the pair of small, wart-like, more or less elevated, lateral setose areas. The pair of apicoventral setal lobes are usually fused with the apicolateral margins of segment X, and are delineated only by their setose surfaces. The dorsal and lateral interlobular gaps are absent. The pair of wart-like lateral setose areas, the vestigia of the preanal appendages, are located centrally on segment X. The spiny ventrocaudal spiny lobe on segment IX are present or absent. This species group is distributed in South and South-East Asia, including the South-East Asian archipelago.

description: We show how a dc current can be generated in a Hall bar without applying a bias voltage. The Hall resistance $R_H$ that corresponds to this pumped current is quantized, just as in the usual integer quantum Hall effect (IQHE). In contrast with the IQHE, however, the longitudinal resistance $R_{xx}$ does not vanish on the plateaus, but equals the Hall resistance. We propose an experimental geometry to measure the pumped current and verify the predicted behavior of $R_H$ and $R_{xx}$.

description: Recent observations with Chandra and XMM-Newton, aided by broad-band spectral coverage from RXTE, have revealed skewed relativistic iron emission lines in stellar-mass Galactic black hole systems. Such systems are excellent laboratories for testing General Relativity, and relativistic iron lines provide an important tool for making such tests. In this contribution to the Proceedings of the 10th Annual Marcel Grossmann Meeting on General Relativity, we briefly review recent developments and present initial results from fits to archival ASCA observations of Galactic black holes. It stands to reason that relativistic effects, if real, should be revealed in many systems (rather than just one or two); the results of our archival work have borne-out this expectation. The ASCA spectra reveal skewed, relativistic lines in XTE J1550-564, GRO J1655-40, GRS 1915+105, and Cygnus X-1.

By means of the Kaloujnine-Krasner theorem, this implies that group extensions with amenable quotients preserve the four aforementioned metric approximation properties. We also discuss the case of co-amenable groups.

description: We report differential I-band and J-band photometry of S Ori 45, a cool (M8.5), young (1-8 Myr) brown dwarf of the sigma Orionis cluster with a likely mass estimated at around 20 times the mass of Jupiter. We detect variability (amplitudes ranging from 34 to 81 mmag) and observe a modulation at a period of 2.5-3.6 h in both optical and near-infrared light curves. The most recent optical data set, however, presents a modulation at the very short period of 46.4+/-1.5 min, which remains a mystery. The origin of the 2.5-3.6 h modulation is analized in terms of various scenarios: inhomogeneous features (dust clouds or magnetically induced dark spots) co-rotating with the object's surface, and presence of an unseen very low-mass companion that is steadily transferring mass to the primary. Because of the very young age of the object and its persistent strong Halpha emission, the possible presence of an accreting disk is also discussed. If the period of a few hours is related to rotation, our results suggest that sigma Orionis low-mass brown dwarfs are rotating faster than more massive cluster brown dwarfs at a rate consistent with their theoretically inferred masses and radii, implying that all of these objects have undergone similar angular momentum evolution.

description: In this paper we present the updated empirical radio surface-brightness-to-diameter ($Σ$--$D$) relation for Galactic supernova remnants (SNRs) calibrated using $110$ SNRs with reliable distances. We apply orthogonal fitting procedure and kernel density smoothing in $Σ-D$ plane and compare the results with the latest theoretical $Σ-D$ relations derived from simulations of radio evolution of SNRs. We argue that the best agreement between the empirical and simulated $Σ-D$ relations is achieved if the mixed-morphology SNRs and SNRs of both, low brightness and small diameter, are filtered out from the calibration sample. The distances to $5$ newly discovered remnants and $27$ new candidates for shell SNRs are estimated from our full and filtered calibration samples.

description: Tubed-reinforced-concrete (TRC) column is an innovated type of composite column that resembles concrete-filled steel tubular (CFST) columns in appearance. Different from CFST columns, the steel tube of a TRC column is terminated at the beam to column connections and the steel tube mainly provides confinement to concrete. In fire conditions, TRC columns may behave very differently as compared to CFST columns. Till now, very few studies have been conducted on the fire behaviour of TRC columns. This paper intends to compare the fire performance of these two kinds of composite columns, which would be helpful to understand the behaviour of TRC columns in fire. Two configurations of CFST columns were investigated, one with rebars and one without. A finite element model was developed using ABAQUS and validated against test results. The effects of load ratios, sectional dimensions, slenderness ratios and load eccentricity ratios on the axial and lateral deformations, load redistributions, fire resistance and failure modes of TRC and CFST columns were analysed. During heating, the axial load is redistributed from the steel tube to the inner section in CFST columns while this load redistribution mainly occurs between concrete and reinforcing bars for TRC columns. The fire resistances of these three kinds of composite are mainly affected by load ratio, sectional dimension and slenderness ratio. The bar-reinforced CFST columns perform best in fire under concentric loading and their fire resistance are around 20% better than those of the TRC columns. As for eccentric loading conditions, the fire performance of TRC columns is the best.

description: Recent studies identified that sequential Recommendation is improved by the attention mechanism. By following this development, we propose Relation-Aware Kernelized Self-Attention (RKSA) adopting a self-attention mechanism of the Transformer with augmentation of a probabilistic model. The original self-attention of Transformer is a deterministic measure without relation-awareness. Therefore, we introduce a latent space to the self-attention, and the latent space models the recommendation context from relation as a multivariate skew-normal distribution with a kernelized covariance matrix from co-occurrences, item characteristics, and user information. This work merges the self-attention of the Transformer and the sequential recommendation by adding a probabilistic model of the recommendation task specifics. We experimented RKSA over the benchmark datasets, and RKSA shows significant improvements compared to the recent baseline models. Also, RKSA were able to produce a latent space model that answers the reasons for recommendation.

description: In an era of heterogeneous data, novel methods and volunteered geographic information provide opportunities to understand how people interact with a place. However, it is not enough to simply have such heterogeneous data, instead an understanding of its usability and reliability needs to be undertaken. Here, we draw upon the case study of Rakiura, Stewart Island where manifested passenger numbers across the Foveaux Strait are known. We have built a population model to ground truth such novel indicators. In our preliminary study, we find that a number of indicators offer the opportunity to understand fluctuations in populations. Some indicators (such as wastewater volumes) can suggest relative changes in populations in a raw form. While other indicators (such as TripAdvisor reviews or Instagram posts) require further data enrichment to get insights into population fluctuations. This research forms part of a larger research project looking to test and apply such novel indicators to inform disaster risk assessments.

SUSY Production From TeV Scale Blackhole at LHC

description: If the fundamental Planck scale is near a TeV, then we should expect to see TeV scale black holes at the LHC. Similarly, if the scale of supersymmetry breaking is sufficiently low, then we might expect to see light supersymmetric particles in the next generation of colliders. If the mass of the supersymmetric particle is of order a TeV and is comparable to the temperature of a typical TeV scale black hole, then such sparticles will be copiously produced via Hawking radiation: The black hole will act as a resonance for sparticles, among other things. In this paper we compared various signatures for SUSY production at LHC, and we contrasted the situation where the sparticles are produced directly via parton fusion processes with the situation where they are produced indirectly through black hole resonances. We found that black hole resonances provide a larger source for heavy mass SUSY (squark and gluino) production than the direct pQCD-SUSY production via parton fusion processes depending on the values of the Planck mass and blackhole mass. Hence black hole production at LHC may indirectly act as a dominant channel for SUSY production. We also found that the differential cross section dσ/dp_t for SUSY production increases as a function of the p_t (up to p_t equal to about 1 TeV or more) of the SUSY particles (squarks and gluinos), which is in sharp contrast with the pQCD predictions where the differential cross section dσ/dp_t decreases as p_t increases for high p_t about 1 TeV or higher. This is a feature for any particle emission from TeV scale blackhole as long as the temperature of the blackhole is very high (~ TeV). Hence measurement of increase of dσ/dp_t with p_t for p_t up to about 1 TeV or higher for final state particles might be a useful signature for blackhole production at LHC.

description: Objectives: Our aim was to examine the effects of an early perinatal prevention program offered to mothers and families suffering from significant psychosocial burden. Methods: All mothers giving birth in a Berlin university hospital during Jan-Aug 2013 were screened with a standardized 27-item questionnaire by trained staff. Mothers with a screening-score ≥ 3, who were not enrolled in other public support programs, were defined as psychosocially burdened. They received a detailed needs assessment and were followed up with counseling. When necessary, affected mothers were voluntarily guided through to specialized 'early support' institutions during the 12-month-intervention period. The historical control group (care-as-usual) consisted of children born at the same hospital the year before.At 12 months postnatally, we interviewed mothers in both groups to assess their stress burden and coping skills by Parenting Stress Index and assessed the current childcare condition. Differences between the groups were compared by multivariable logistic regression analyses adjusting for potential confounders. Results: The intervention group and the control group included 225 and 157 families, respectively. After 12-months, mothers in the 'early support' intervention group had significantly less often depression (adjusted odds ratio 0.25, 95%-confidence interval 0.07-0.94), less often a disturbed relationship with the parenting partner (0.34, 0.10-1.14) and reported reduced stress due to the child's demands (0.40, 0.15-1.10) compared to the control group. Childcare indicators did not differ between the 2 groups. Conclusions: In mothers at high psychosocial risk, the 'early support' intervention program Babylotse-Plus seemed to reduce the occurrence of depression and several stress indicators in the first postnatal year.

description: The multi-centre metrics are a family of euclidean solutions of the empty space Einstein equations with self-dual curvature. For this full class, we determine which metrics do exhibit an extra conserved quantity quadratic in the momenta, induced by a Killing-St\" ackel tensor. Our systematic approach brings to light a subclass of metrics which correspond to new classically integrable dynamical systems. Within this subclass we analyze on the one hand the separation of coordinates in the Hamilton-Jacobi equation and on the other hand the construction of some new Killing-Yano tensors.

description: Microcavity electron-hole-photon systems in two-dimensions are long anticipated to exhibit a crossover from Bose-Einstein condensate (BEC) to Bardeen-Cooper-Schrieffer (BCS) superfluid, when carrier density is tuned to reach the Mott transition density. Yet, theoretical understanding of such a BEC-BCS crossover largely relies on the mean-field framework and the nature of the carriers at the crossover remains unclear to some extent. Here, motivated by the recent demonstration of a BCS polariton laser {[}Hu \textit{et al.}, arXiv:1902.00142{]} and based on a simplified short-range description of the electron-hole attraction, we examine the role of quantum fluctuations in an exciton-polariton condensate at thermal equilibrium and determine the number of different type carriers at the crossover beyond mean-field. Near Mott density and with ultra-strong light-matter coupling, we find an unexpectedly large phase window for a strongly correlated BCS polariton condensate, where both fermionic Bogoliubov quasi-particles and bosonic excitons are significantly populated and strongly couple to photons. We predict its photoluminescence spectra and show that the upper polariton energy gets notably renormalized, giving rise to a high-energy side-peak at large carrier density, as observed in recent experiments.

Απώτερος στόχος των ισχυουσών διατάξεων είναι η προάσπιση των δικαιωμάτων των ψηφιακών καταναλωτών και η προστασία τους από τις καταχρηστικές και αθέμιτες πρακτικές, που εφαρμόζουν οι επιχειρήσεις με σκοπό το κέρδος τους, αλλά και η διασφάλιση πως οι χρήστες των κοινωνικών δικτύων, όχι μόνο ως καταναλωτές αλλά και ως φορείς προσωπικών δεδομένων, θα νιώθουν ασφαλείς και θα ενθαρρύνονται να προβαίνουν σε ηλεκτρονικές συναλλαγές. Σκοπός της παρούσας είναι η μελέτη του τρόπου διεξαγωγής του ηλεκτρονικού εμπορίου μέσω των κοινωνικών δικτύων, καθώς και του νομικού πλαισίου που περιβάλλει τις ηλεκτρονικές αυτές συναλλαγές. Πιο συγκεκριμένα, θα αναλυθεί το νομοθετικό πλαίσιο που ρυθμίζει τις σχέσεις πωλητή-καταναλωτή και προστατεύει τα συμφέροντα του τελευταίου. Στη συνέχεια θα γίνει αναφορά στους κανόνες σύμφωνα με τους οποίους οφείλει να λειτουργεί η διαφήμιση ώστε να διασφαλίζεται η ελεύθερη λήψη αγοραστικών αποφάσεων από τους καταναλωτές. Τέλος, παρουσιάζονται οι κανόνες εκείνοι που έχουν τεθεί για την προάσπιση των προσωπικών δεδομένων των χρηστών - ψηφιακών καταναλωτών από τους κινδύνους υφαρπαγής και μη σύννομης επεξεργασίας τους, στα πλαίσια της διεξαγωγής του ηλεκτρονικού εμπορίου μέσω των κοινωνικών δικτύων.

description: Orbital current order of the d-density-wave type (DDW) has been postulated to explain the pseudogap in the high temperature superconductors. We have performed neutron scattering experiments to search for this order and show here the results obtained on an YBa2Cu3O6.45 sample using the best neutron spectrometers available. We argue that the data are consistent with a small, largely c-axis-directed moment, found below about 200K.

description: We study the instantons describing the production of particles at the ends of codimension-one objects (strings and struts) in $(2+1)$-dimensional Minkowski and de Sitter spaces. A Minkowskian background allows only for systems with vanishing total mass, so that either negative mass particles or negative tension struts are required. On a de Sitter background, on the other hand, we find processes describing the production of string/particle systems with no negative energies involved. We also compute the probabilities of creating and of breaking an infinite cosmic string in de Sitter space. We perform our analysis of the system in de Sitter space employing a generalization of the toroidal coordinate system to the three-sphere.

description: Colorectal cancer (CRC) is one of the most common malignancies worldwide. Early stage CRC patients have a good prognosis. If distant metastasis occurs, the 5-year survival drops below 10%. Despite treatment success over the last decades, treatment options for metastatic disease are still limited. Therefore, novel targets are needed to foster therapy of advanced stage CRC patients and hinder progression of early stage patients into metastasis. A novel target is the crucial oncogene Metastasis-Associated in Colon Cancer 1 (MACC1) involved in molecular pathogenesis of CRC metastasis. MACC1 induces cell proliferation and motility, supports cellular survival and rewires metabolism resulting in increased metastasis in vivo. MACC1 is a prognostic biomarker not only for CRC but for more than 20 solid cancer entities. Inflammation plays a pivotal role in tumorigenesis, tumor progression and metastasis. For CRC, inflammatory bowel disease and ulcerative colitis are important inflammation associated risk factors. Certain cytokines, such as TNF-α and IFN-γ, are key factors in determining the contribution of the inflammatory process to CRC. Knowledge of the connection between inflammation and MACC1 driven tumors remains unclear. Gene expression analysis of CRC cells after cytokine stimulation was analyzed by qRT-PCR and Western blot. Cellular motility was assessed by Boyden chamber assays. MACC1 promoter activity after stimulation with pro-inflammatory cytokines was measured using promoter-luciferase constructs. To investigate signal transduction from receptor to effector molecules, blocking experiments using neutralizing antibodies and knockdown experiments were performed. Following TNF-α stimulation, MACC1 and c-Jun expression were significantly increased at the mRNA and protein level. Knockdown of c-Jun reduced MACC1 inducibility following TNF-α stimulation. TNF-α promoted MACC1-induced cell migration that was reverted following MACC1 knockdown. Moreover, MACC1 and c-Jun expression were downregulated by blocking TNFR1, but not TNFR2. Knock down of the NF-κB subunit, p65, reduced basal MACC1 and c-Jun mRNA expression levels. Adalimumab, a clinically approved monoclonal anti-TNF-α antibody, hindered MACC1 induction. The present study highlights that TNF-α regulates the induction of MACC1 via the NF-κB subunit p65 and the transcription factor c-Jun in CRC cells. This finding unravels a novel signaling pathway upstream of MACC1 and provides a potential therapeutic target for the treatment of CRC patients with an associated inflammation.

description: One of the main goals for hadron colliders is the study of the properties of the third generation quarks. We study the signatures for new TeV resonances that couple to top or bottom quarks both at the Tevatron Run II and at the LHC. We find that in the simplest production processes of Drell-Yan type at the Tevatron, the signals are overwhelmed by QCD backgrounds. We also find that it is possible to study these resonances when they are produced in association with a pair of heavy quarks or in association with a single top at the LHC.In particular, with an integrated luminosity of 300 fb$^{-1}$ at the LHC, it is possible to probe resonance masses up to around 2 TeV.

description: Purpose: This article discusses the results of an evaluation of the one-year implementation period of an integrative care program at a pediatric oncology ward, which consists of integrative care treatments offered three times a week to the patients. The guiding questions are how the model was implemented, which factors have to be considered for successful implementation, and which factors showed to be obstacles during implementation. Methods: A mixed-methods approach was applied for data saturation. Qualitative data consist of participant observations and informal conversations during the implementation phase. All observational records were filed in the data program MAXQDA. For the quantitative data, all integrative care treatments applied on the intensive care unit were documented and subsequently filed in an Excel sheet. Both sets of data were analyzed for the evaluation. Results: Four main thematic clusters influenced the implementation: (1) the organization and structure of the intensive care unit; (2) mood and atmosphere; (3) feedback on treatment; and (4) time and experience. All factors are interlinked and cannot be looked at independently. Results of the quantitative data show that the most frequent used treatments were those with calming and relaxing effects, followed by treatments for stomachache, nausea, and obstipation. Conclusions: The implementation of an integrative model of care is a process that demands thorough understanding of the complex setting of the ward, ongoing adaptation to the structures and organization of the ward, and the integration of factors like feedback, time, atmosphere, and the mood of parents, patients, and nurses.
Defect CFT in the 6d (2,0) theory from M2 brane dynamics in AdS$_7 \times$S$^4$

description: Surface operators in the 6d (2,0) theory at large $N$ have a holographic description in terms of M2 branes probing the AdS$_7 \times S^4$ M-theory background. The most symmetric, 1/2-BPS, operator is defined over a planar or spherical surface, and it preserves a 2d superconformal group. This includes, in particular, an $SO(2,2)$ subgroup of 2d conformal transformations, so that the surface operator may be viewed as a conformal defect in the 6d theory. The dual M2 brane has an AdS$_3$ induced geometry, reflecting the 2d conformal symmetry. Here we use the holographic description to extract the defect CFT data associated to the surface operator. The spectrum of transverse fluctuations of the M2 brane is found to be in one-to-one correspondence with a protected multiplet of operator insertions on the surface, which includes the displacement operator. We compute the one-loop determinants of fluctuations of the M2 brane, and extract the conformal anomaly coefficient of the spherical surface to order $N^0$. We also briefly discuss the RG flow from the non-supersymmetric to the 1/2-BPS defect operator, and its consistency with a "$b$-theorem" for the defect CFT. Starting with the M2 brane action, we then use AdS$_3$ Witten diagrams to compute the 4-point functions of the elementary bosonic insertions on the surface operator, and extract some of the defect CFT data from the OPE. The 4-point function is shown to satisfy superconformal Ward identities, and we discuss a related subsector of "twisted" scalar insertions, whose correlation functions are constrained by the residual superconformal symmetry.

description: We present observations of the young stars TW Hya and HD 100546 made with the Australia Telescope Compact Array at 89 GHz with $\sim2''$ resolution and $\sim3$ mJy continuum sensitivity. Compact thermal dust continuum emission is detected from disks surrounding both stars. HD 100546 also shows hints of extended emission, presumably a residual protostellar envelope, which is also visible in scattered light at optical wavelengths. For TW Hya, HCO$^+$ J=1--0 line emission from the circumstellar disk is detected and spatially resolved. The observed size and intensity are in good agreement with model calculations based on an irradiated disk with substantial depletions derived previously from single dish observations of higher-J HCO$^+$ transitions.

description: OBJECTIVES: Outcome and comparator choice strongly determine the validity and implementation of clinical trial results. We aimed to assess outcome and comparator choice in intervention studies on molar incisor hypomineralisation (MIH) using systematic review and social network analysis (SNA). DESIGN AND DATA SOURCES: Medline, Embase, Cochrane Central, Google Scholar, opengrey.eu as well as DRKS.de and Clinicaltrials.gov were searched for MIH intervention studies. The search covered the period from 1980 to 2019. ELIGIBILITY CRITERIA: Clinical single-arm/multiarm, controlled/uncontrolled studies reporting on the management of MIH were included. Reported outcomes and comparators were extracted and categorised. SNA was used to evaluate comparator choice and the resulting trial networks. DATA EXTRACTION: Of the 7979 identified records, 100 were evaluated in full text and 35 studies (17 randomised controlled trials, 14 prospective and 4 retrospective cohort studies) were included. RESULTS: In total, 2124 patients with a mean age of 11 years (min/max 6/70 years) were included. Outcomes fell in one of 11 different outcome categories: restoration success, aesthetic improvement, pain/hypersensitivity/discomfort, mineral gain, space management, anaesthesia effectiveness, preventive success, efficiency, quality of life, gingival and periodontal health and patient satisfaction. Comparators were mainly restorative interventions (17 studies), remineralisation (3), treatment of hypersensitivity (10), aesthetic interventions (5) and orthodontic interventions (3). Two highly clustered comparator networks emerged; many interventions were not robustly linked to these networks. CONCLUSIONS: MIH intervention studies recorded both clinically centred and patient-centred outcomes. Core outcome set development should consider these and supplement them with outcomes on, for example, applicability. The high number of compared interventions tested in only few studies and our SNA results implicate that the current evidence may not be robust.

description: For Young systems, i.e. for hyperbolic systems without/with singularities satisfying Lai-Sang Young's axioms (which imply exponential decay of correlation and the CLT) a local CLT is proven. In fact, a unified version of the local CLT is found, covering among others the absolutely contionuous and the arithmetic cases. For the planar Lorentz process with a finite horizon this result implies a.) the local CLT and b.) the recurrence. For the latter case ($d=2$, finite horizon), combining the global CLT with abstract ergodic theoretic ideas, K. Schmidt, and J.-P. Conze, could already establish recurrence.
