description: The diffusion of substrate material into absorbing layer and oxidation of metal substrate or cermet metal nanoparticles at high temperatures are known as inevitable problems of the solar selective absorbers. In this study, we consider the use of textured stainless steel (SS) surface coated with a protective AlCr oxide layer as a high temperature solar selective absorber. The textured SS surface was prepared by ion etching techniques and AlCr oxide protective layer was deposited by RF magnetron sputtering. The absorptivity and emissivity of the as-prepared absorbers were 0.86-0.92 and 0.151-0.168, respectively. In order to evaluate the thermal stability, the absorbers were annealed at 600-800 C for different time in ambient atmosphere. Absorbers demonstrated a red shift of the onset of the reflectivity at all annealing temperatures. The high activation energy of 315 kJ/mol was calculated. The service lifetime of the absorbers at 500 C was estimated to be about 100 years and at 700 and 800 C the absorbers were stable about 50 and 1 hours, respectively. A detailed examination of the annealed absorber surface revealed growth of surface Mn3O4 nanocrystals, which resulted in observed change of the reflectance spectra, while the textured surface morphology had no significant change. The results show that the protective textured surface has much higher thermal stability in air than iron based cermet absorbers.

description: We present a simple method to automatically evaluate arbitrary tree-level amplitudes involving the production or decay of a heavy quark pair QQbar in a generic {2S+1}L_J^[1,8] state, i.e., the short distance coefficients appearing in the NRQCD factorization formalism. Our approach is based on extracting the relevant contributions from the open heavy quark-antiquark amplitudes through an expansion with respect to the quark-antiquark relative momentum and the application of suitable color and spin projectors. To illustrate the capabilities of the method and its implementation in MadGraph a few applications to quarkonium collider phenomenology are presented.

Year: 2018

description: Unfolded protein response (UPR) as collective signal transduction pathways is essential for surviving the endoplasmic reticulum (ER) stress in vertebrates and invertebrates. Upon accumulation of unfolded proteins in the ER lumen, UPR increases the degradative and protein-folding capacities of cells and decreases global protein synthesis to maintain the cell homeostasis. Because of their importance in cellular stress and protein folding process, UPR signaling pathways receive increasing attentions, and their components and multiple regulation functions have been well characterized in mammals, fly, and worm etc. Molluscs are widely distributed in various environments with high species diversity, which exhibit remarkable capacity for adaptation and survival upon diverse stressors. Because of the homeostatic role in response to ER stress, the knowledge about UPR would be helpful for understanding the wide distributions, living habits and adaptability to the environment of molluscs. This review summarizes the UPR signaling pathways in molluscs with the emphasis on recent research progresses about the characteristics of molluscan UPR signaling pathway members and their expression profiles in response to various environmental stressors.

description: Though fly ash in South Africa has mainly been utilized in the construction industry, a large portion of it is still discarded. Production of glass-ceramic composites through fly ash devitrification has gradually become one of the applications being examined internationally. This study reports the investigation of producing glass-ceramic composites from fly ash and varying quantities of beverage waste glass and magnesium oxide as main raw materials. Glasses were obtained by melting fly ash and its additives using an arc furnace. Based on their behaviour when subjected to differential thermal analysis, the glasses were then crystallised through a double-staged thermal treatment to form glass-ceramic composites. The composition and behaviour of the glass-ceramic composites were investigated using X-ray diffraction, Scanning Electron Microscopy, mechanical and chemical assessments. The crystal content in the glass-ceramic composites increased as the magnesium oxide content was increased. The desired diopside phase decreased with an increased magnesium oxide content and ultimately resulted in the formation of forsterite and anorthite as the major and second major phases respectively. The glass-ceramic composites with lesser amounts of magnesium oxide were chemically and thermally resistant and they also demonstrated high cold compressive strength.

description: In this study, we aimed to determine how infection with Nosema ceranae spores affected semen volume, sperm concentration, and fragmentation of sperm DNA in honeybees. A total of 120 one-dayold drones were marked with queen bee marking numbers, and equally divided into two groups. Drones in the infected group were individually fed with honey syrup containing 200 000 N. ceranae spores per 1 µL, while those in the uninfected (control) group were fed honey syrup without spores. The groups were then placed in two separate colonies. Fourteen days later, ejaculate was collected from the drones and was analyzed for semen volume, sperm concentration per 1 µL semen, and sperm DNA fragmentation. Compared to uninfected controls, the N. ceranae spore-infected drones showed significantly decreased semen volume and sperm concentration, as well as a higher percentage of sperm DNA fragmentation.

description: The vaḍukar country is where the roots of most of us lie. But before we return to that land of our ancestors, we need to set right a few misconceptions. The first is the false relationship between the occupation and the group tag that we carry. We have already made it clear, on the basis of irrefutable evidence, that the caturvarṇa (chaturvarna) classification had nothing to do with the occupation; that the brāmhaṇa were not priests by definition, and the kshatriya were not warriors, and so on. As Kane categorically states, it was all about ‘groups of people having a skin of a dark or fair colour’, all about varṇa. [Kane, 1941 : History Of Dharmaśāstra,Vol. II, Part 1, 25] That is, the classification was ‘more or less racial and cultural’. [Kane, 1941 : Vol. II, Part 1, 48] That the brāmhaṇa happened to eventually occupy most of the sacerdotal space was merely an outcome of certain historical circumstances. As we have seen before, the most of the kings in Deccan were dhangar.

description: We investigate the use of Kelly's strategy in the construction of an optimal portfolio of assets. For lognormally distributed asset returns, we derive approximate analytical results for the optimal investment fractions in various settings. We show that when mean returns and volatilities of the assets are small and there is no risk-free asset, the Kelly-optimal portfolio lies on Markowitz Efficient Frontier. Since in the investigated case the Kelly approach forbids short positions and borrowing, often only a small fraction of the available assets is included in the Kelly-optimal portfolio. This phenomenon, that we call condensation, is studied analytically in various model scenarios.

description: We measure the dynamical mechanical properties of human red blood cells. Single cell response is measured with optical tweezers. We investigate both the stress relaxation following a fast deformation, and the effect of varying the strain rate. We find a power law decay of the stress as a function of time, down to a plateau stress, and a power law increase of the cell's elasticity as a function of the strain rate. Interestingly, the exponents of these quantities violate the linear superposition principle, indicating a nonlinear response. We propose that this is due to breaking of a fraction of the crosslinks during the deformation process. The Soft Glassy Rheology Model accounts for the relation between the exponents we observe experimentally. This picture is consistent with recent models of bond remodeling in the red blood cell's molecular structure. Our results imply that the blood cell's mechanical behavior depends critically on the deformation process.

description: Myeloid leukemia factor (MLF) plays an important role in the development of Drosophila. It is reported that MLF could inhibit white spot syndrome virus (WSSV) replication in shrimp. However, the function and mechanism of MLF in shrimp antibacterial immunity are still elusive. In this study, we found MjMLF could be upregulated by Vibro anguillarum challenge in hemocytes, gills, and intestine of kuruma shrimp. RNAi assay showed that MjMLF could facilitate bacterial clearance in shrimp, and it was beneficial for shrimp survival post V. anguillarum infection. Pull down assay showed that rMjMLF could bind to rMj14-3-3 in vitro. Some antimicrobial peptide genes could be regulated by MjMLF. The results indicated that MjMLF might participate in the anti-bacterial immune reaction of shrimp.

Low temperature mean opacities for the carbon-rich regime

Year: 2007

description: Asymptotic Giant Branch (AGB) stars undergo a change in their chemical composition during their evolution. This in turn leads to an alteration of the radiative opacities, especially in the cool layers of the envelope and the atmosphere, where molecules are the dominant opacity sources. A key parameter in this respect is the number ratio of carbon to oxygen atoms (C/O). In terms of low temperature mean opacities, a variation of this parameter usually cannot be followed in stellar evolution models, because up to now tabulated values were only available for scaled solar metal mixtures (with C/O ~ 0.5). We thus present a set of newly generated tables containing Rosseland mean opacity coefficients covering both the oxygen-rich (C/O < 1) and the carbon-rich (C/O > 1) regime. We compare our values to existing tabular data and investigate the relevant molecular opacity contributors.

description: This thesis explores the hypothesis that a biometal binding agent is able to deliver enhanced quantities of the biometals zinc and copper into the specialised blood vessel cells which form the interface between the brain and the blood, and subsequently modify the relative abundance and function of P-glycoprotein, an important toxin transporting protein, in both laboratory and animal settings. The successful modulation of P-glycoprotein by biometal delivery may find application in the modification of brain-to-blood transport of natural toxins in Alzheimer's disease, or in the modulation of pharmaceutical access to the central nervous system.

description: The influence of the individual equiaxed and columnar cast structure on the evolution of texture during thermo-mechanical processes (TMP) was investigated using the electron backscatter diffraction (EBSD) technique. In this study, the effect of the individual IECS versus ICCS on texture evolution during rolling and annealing process was investigated. The recrystallization texture after cold working and annealing was then related to mechanical properties of the initial cast structures. It was found that the initial equiaxed cast structure exhibited a homogenous fiber texture while the columnar developed an inhomogeneous texture with the predominance of both the Goss and fiber textures. While texture has a significant influence on surface smoothness of the drawn product, it was found that it did not significantly affect the yield strength and ultimate tensile strength (UTS), but marginally affected the elongation i.e. it was found to be slighted higher for the equiaxed than the columnar cast structure measured parallel to the rolling direction (RD).

description: In the present study, a thaumatin-like protein (CgTLP) was identified from the oyster Crassostrea gigas. The full-length cDNA of CgTLP was of 913 bp with a 5’ untranslated regions (UTR) of 98 bp, a 3’ UTR of 80 bp, and an open reading frame (ORF) of 735 bp encoding a polypeptide of 244 residues. The CgTLP gene was expressed ubiquitously in mantle, gonad, hemocytes, hepatopancreas, gill, and adductor muscle with the higher expression levels in adductor muscle, hemocytes, and hepatopancreas. Immunofluorescence assay indicated that CgTLP was mainly distributed in the cytoplasm of hemocytes. The mRNA expression levels of CgTLP in hemocytes were significantly up-regulated after the stimulations with mannan (13.69-fold, p < 0.05), Pichia pastoris (8.85-fold, p < 0.05) and polyinosinic-polycytidylic acid (3.62-fold, p < 0.05), but did not change significantly after stimulations with lipopolysaccharide, peptidoglycan, and Vibrio splendidus. The recombinant CgTLP protein (rCgTLP) significantly inhibited the proliferation of P. pastoris (p < 0.05), while no inhibition towards Staphylococcus aureus and V. splendidus. rCgTLP also displayed obvious β-1,3-glucanase activity, while no enzymatic activity towards chitin. These results collectively indicated that CgTLP was a homologue of TLP, which might play a vital role in defensing against fungal infection in C. gigas.

description: Despite the low diversity and high variability at intra- and interspecific levels, gut microbiota of insect play important roles in digesting and absorbing nutrients, health and development, even in resistance and immunity. In this study, we investigate the composition and diversity of gut microbiota in the 5 th instar of silkworm larvae since the mount of ingested mulberry leaves of this stage is about 85% of the total amount. Intestinal contents were collected at 0, 12, 24, 48 and 72h in the 5 th instar. 32, 21, 29, 24, 14 phyla and 386, 163, 292, 196, 144 genera were detected respectively in the samples described above. In general, the dominated phyla in the larvae gut were Firmicutes, Cyanobacteria, Proteobacteria, Actinobacteria and Bacteroidetes; the dominated genera were Enterococcus, Staphylococcus, Arthrobacter, Pseudomonas, Lactobacillus, Bacteroides, Paenibacillus and Serratia, respectively. The range of phyla and genera was different and there were two peaks of microbial diversity at 0 and 24 h. Compared with the intestinal bacteria of these time points, there were unique bacteria and 56 common ones. In these bacteria, the abundance of Gram-positive bacteria including Enterococcus and Staphylococcus were the highest. Our results provided foundation and reference on the research of intestinal microorganisms and resistance breeding in silkworm.

description: Elie Metchnikoff was a Russian scientist known as the pioneer of innate immunity. In particular, he was awarded the Nobel Prize for discovering the process of phagocytosis and its significance in the development and disease. Here, we endeavor to demonstrate the enduring fascination of his scientific research, in particular the experiment involving the first observation of a macrophage reaction in the sea star. This applies to both adult and larvae immunity studies. Recent work on sea star larval cellular immunity and adult immune systems using modern expansions of molecular and cellular techniques shows that it is a continually exciting research field that cannot just be consigned to history. Finally, aspects of human scientific roles - from the zoologist to embryological experiences to the father of innate immunity - can teach us much about the oft-neglected added value of multidisciplinary knowledge and integration in animal science research.

description: We analyze the motion of a {\it massless} and {\it chargeless} particle very near to the event horizon. It reveals that the radial motion has exponential growing nature which indicates that there is a possibility of inducing chaos in the particle motion of an integrable system when it comes under the influence of the horizon. This is being confirmed by investigating the Poincar$\acute{e}$ section of the trajectories with the introduction of a harmonic trap to confine the particle's motion. Two situations are investigated: (a) {\it any} static, spherically symmetric black hole and, (b) spacetime represents a stationary, axisymmetric black hole (e.g., Kerr metric). In both cases, the largest Lyapunov exponent has upper bound which is the surface gravity of the horizon. We find that the inclusion of rotation in the spacetime introduces more chaotic fluctuations in the system. The possible implications are finally discussed.

description: We present results of non-linear, 2D, numerical simulations of magneto-acoustic wave propagation in the photosphere and chromosphere of small-scale flux tubes with internal structure. Waves with realistic periods of three to five minutes are studied, after applying horizontal and vertical oscillatory perturbations to the equilibrium model. Spurious reflections of shock waves from the upper boundary are minimized thanks to a special boundary condition. This has allowed us to increase the duration of the simulations and to make it long enough to perform a statistical analysis of oscillations. The simulations show that deep horizontal motions of the flux tube generate a slow (magnetic) mode and a surface mode. These modes are efficiently transformed into a slow (acoustic) mode in the vA < cS atmosphere. The slow (acoustic) mode propagates vertically along the field lines, forms shocks and remains always within the flux tube. It might deposit effectively the energy of the driver into the chromosphere. When the driver oscillates with a high frequency, above the cut-off, non-linear wave propagation occurs with the same dominant driver period at all heights. At low frequencies, below the cut-off, the dominant period of oscillations changes with height from that of the driver in the photosphere to its first harmonic (half period) in the chromosphere. Depending on the period and on the type of the driver, different shock patterns are observed.

description: The interaction of streamers in nitrogen-oxygen mixtures such as air is studied. First, an efficient method for fully three-dimensional streamer simulations in multiprocessor machines is introduced. With its help, we find two competing mechanisms how two adjacent streamers can interact: through electrostatic repulsion and through attraction due to nonlocal photo-ionization. The non-intuitive effects of pressure and of the nitrogen-oxygen ratio are discussed. As photo-ionization is experimentally difficult to access, we finally suggest to measure it indirectly through streamer interactions.

description: We solve the q-state Potts model with anti-ferromagnetic interactions on large random lattices of finite coordination. Due to the frustration induced by the large loops and to the local tree-like structure of the lattice this model behaves as a mean field spin glass. We use the cavity method to compute the temperature-coordination phase diagram and to determine the location of the dynamic and static glass transitions, and of the Gardner instability. We show that for q>=4 the model possesses a phenomenology similar to the one observed in structural glasses. We also illustrate the links between the positive and the zero-temperature cavity approaches, and discuss the consequences for the coloring of random graphs. In particular we argue that in the colorable region the one-step replica symmetry breaking solution is stable towards more steps of replica symmetry breaking.

We introduce a problem that we call the \emph{leaf realization problem}, which consists in deciding whether, for a given sequence of $n+1$ natural numbers $(\ell_0, \ell_1, \ldots, \ell_n)$, there exists a simple graph $G$ with $n$ vertices such that $\ell_i = L_G(i)$ for $i = 0, 1, \ldots, n$. We present basic observations on the structure of these sequences for general graphs and trees. In the particular case where $G$ is a caterpillar graph, we exhibit a bijection between the set of the discrete derivatives of the form $(ΔL_G(i))_{1 \leq i \leq n - 3}$ and the set of prefix normal words.

description: Youth with vision impairment have the right to experience wellbeing. One key way of supporting this right lies in the educational and rehabilitation services provided to them. Current research shows that these services are not always successful in supporting the wellbeing of young people with vision impairment. Ross Anderson’s research explores how youth with vision impairment define and maintain wellbeing to guide the development of these services. He found that services should look to promote a holistic conception of wellbeing, in which young people’s senses of balance across their experiences of success, independence, social connection and physical health are emphasised.
Massive neutron star with strangeness in a relativistic mean-field model with a high-density cut-off

description: The properties of strangeness neutron star are studied within relativistic mean-field (RMF) model via including a logarithmic interaction as a function of scalar meson field. This logarithmic interaction, named as the $σ$-cut potential, can largely reduce the attractive contributions of scalar meson field at high density without any influence on nuclear structure around normal saturation density. In this work, the TM1 parameter set is chosen as the RMF interaction, while the strengths of logarithmic interaction are constrained by the properties of finite nuclei so that we can obtain a reasonable effective nucleon-nucleon interaction. The hyperons, $Λ,~Σ$, and $Ξ$ are also considered in neutron stars within this framework, whose coupling constants with mesons are determined by the latest hyperon-nucleon and $Λ$-$Λ$ potentials extracted from the experimental data of hypernuclei. The maximum mass of neutron star can be larger than two solar mass with these hyperons. Furthermore, the nucleon mass at high density will be saturated due to this additional $σ$-cut potential, which is consistent with the conclusions from the microscopic calculations such as, Brueckner-Hartree-Fock theory and quark mean-field model.

The mechanism utilized by Toxoneuron nigriceps in inhibiting the host immune system
Creators: name: Falabella, P
Publisher: name: Invertebrate Survival Journal
Year: 2018

description: Insect parasitic factors of both maternal and embryonic origin allow the endoparasitoid progeny to elude the humoral and cellular immune system responses of their host. Endoparasitoid wasps of lepidopteran larval stages inject, along with venom and ovarian proteins, Polydnavirus particles acting in synergy with all other factors in host regulation for parasitism success. To date, the molecular mechanisms used by endoparasitoid to circumvent the host immune system are little known. Neverthless, several of these strategies are conserved through the wasp parasitoid species. Heliothis virescens is a noctuid moth, host of the endophagous parasitoid Toxoneuron nigriceps. The first observed effect of parasitism is immune system suppression, as direct consequence of the array of host regulation factors, both of embryonic and maternal origin. This review describes the contribution of all the parasitic components during alterations of the host immune response observed after oviposition by T. nigriceps.

description: Thermalizing quantum systems are conventionally described by statistical mechanics at equilibrium. However, not all systems fall into this category, with many body localization providing a generic mechanism for thermalization to fail in strongly disordered systems. Many-body localized (MBL) systems remain perfect insulators at non-zero temperature, which do not thermalize and therefore cannot be described using statistical mechanics. In this Colloquium we review recent theoretical and experimental advances in studies of MBL systems, focusing on the new perspective provided by entanglement and non-equilibrium experimental probes such as quantum quenches. Theoretically, MBL systems exhibit a new kind of robust integrability: an extensive set of quasi-local integrals of motion emerges, which provides an intuitive explanation of the breakdown of thermalization. A description based on quasi-local integrals of motion is used to predict dynamical properties of MBL systems, such as the spreading of quantum entanglement, the behavior of local observables, and the response to external dissipative processes. Furthermore, MBL systems can exhibit eigenstate transitions and quantum orders forbidden in thermodynamic equilibrium. We outline the current theoretical understanding of the quantum-to-classical transition between many-body localized and ergodic phases, and anomalous transport in the vicinity of that transition. Experimentally, synthetic quantum systems, which are well-isolated from an external thermal reservoir, provide natural platforms for realizing the MBL phase. We review recent experiments with ultracold atoms, trapped ions, superconducting qubits, and quantum materials, in which different signatures of many-body localization have been observed. We conclude by listing outstanding challenges and promising future research directions.

description: This inquiry proposes a process for creating intercultural theatre collaboratively: a Syncretic Dramaturgy for Devising (SDD), conceptualised by reviewing established frameworks and reflecting on my lived experience and praxis. This study and its outcomes expand understandings of extant scholarship and practice hitherto focused on text-based syncretic theatre. Additionally, it foregrounds a novel, countercolonial approach to researching contemporary New Intercultural Theatre made in a formerly colonising country. This submission builds on Michel de Certeau’s (1984) distinction between maps and itineraries, thus mapping the development of the SDD and providing a critical reflexive account of its realisation in practice. The SDD is the key outcome of this research and will be available as a tool for theatre makers with an interest in devising intercultural theatre that avoids theatrical exoticism. The Syncretic Theatre Lab (STL) constitutes a second key outcome of this research, comprising workshops held in Glasgow and Edinburgh between February and April 2018. The written thesis, Volume I, provides context, discusses how the SDD was developed, reflects on the practice, and contrapuntally evaluates the study in relation to extant literature and hegemonic theatre practices. Volume II is a website-portfolio documenting the practice component of the research, which can be read in a linear or non-linear way, in alignment with De Certeau’s idea of different trajectories. Anna Fenemore’s (2012) four processes for devised performance practice are adapted into an original research apparatus facilitating the implementation of the hybrid methodology designed for this study: Practice-as-Research inflected with Autoethnography. Drawing on Christopher Balme’s (1999) systematic analysis of syncretic plays, the actors’ Cultural Texts were used as stimuli for devising in the STL. A narrative analysis details the formulation of the SDD, identifying the operations within the process and framing Syncretic Theatre as a dramaturgical form and theatremaking method as well as onstage representation.
Structure and properties of the vacuum of the Twisted Eguchi-Kawai model

description: We investigate numerically the phase structure of the Twisted Eguchi-Kawai (TEK) model in four dimensions. In the numerical simulations of the zero temperature TEK model (using a symmetric twist) we observe the existence of new phases that break its centre symmetry at intermediate lattice couplings and for large SU(N) gauge groups. This effect can be explained by the contribution of diagonal configurations with collapsed eigenvalues, which are particular cases of ``generalised fluxons''. We also investigate finite temperature versions of the TEK model using anisotropic lattice couplings, where in particular we find van Baal fluxons contributing at large anisotropies.

description: This report investigates the dynamics of time allocation of men, women, and children in various types of work in rural households in Ghana. Using primary data and the Ghana Time Use Survey (GTUS) 2009, it examines gendered differences in time allocation and the interaction between income, various household types and time use. Moreover, women’s time use patterns and their relationship to children’s diets are analysed. We also assess patterns of time use and their relationship with productivity. Finally, domestic and agricultural technologies and time use patterns are assessed. The study finds persistent gender gaps, with women and girls disproportionately engaged in unpaid work across different household compositions and income groups. Household characteristics, such as single- adult households and income levels, shape time allocation, influencing the distribution of work among family members. Moreover, women's time on unpaid activities shows a positive association with children's dietary diversity, underscoring the importance of women's involvement in household chores and caregiving for nutritional outcomes. However, the study finds that women's time in unpaid work negatively impacts their labour productivity, suggesting potential trade-offs between domestic responsibilities and economic participation. Access to technologies and services, such as agricultural tools and markets, appears to play a role in shaping time use patterns and women's engagement in paid activities. The findings suggest policy implications for reducing the burden of unpaid work through technological interventions, redistributing household responsibilities, and promoting gender equality to enhance women's economic empowerment and household well-being.

description: Hot core molecules should be detectable in external active galaxies out to high redshift. We present here a detailed study of the chemistry of star-forming regions under physical conditions that differ significantly from those likely to be appropriate in the Milky Way Galaxy. We examine, in particular, the trends in molecular abundances as a function of time with respect to changes in the relevant physical parameters. These parameters include metallicity, dust:gas mass ratio, the H$_{2}$ formation rate, relative initial elemental abundances, the cosmic ray ionization rate, and the temperature of hot cores. These trends indicate how different tracers provide information on the physical conditions and on evolutionary age. We identify hot core tracers for several observed galaxies that are considered to represent spirals, active galaxies, low-metallicity galaxies, and high-redshift galaxies. Even in low-metallicity examples, many potential molecular tracers should be present at levels high enough to allow unresolved detection of active galaxies at high redshift containing large numbers of hot cores.

description: We have observed a 3° × 3° area centered on the M81/M82 group of galaxies using the Robert C. Byrd Green Bank Telescope in a search for analogs to the high-velocity clouds of neutral hydrogen found around our Galaxy. The velocity range from –605 to –85 km s–1 and from 25 to 1970 km s–1 was searched for H I clouds. Over the inner 2° × 2° the 7σ detection threshold was 9.6 × 105 M . We detect five previously unknown H I clouds associated with the group, as well as numerous associated filamentary H I structures, all lying in the range –105 ≤ V helio ≤ +280 km s–1. From the small angular distance of the clouds to group members, and the small velocity difference between group members and clouds, we conclude that the clouds are most likely relics of ongoing interactions between galaxies in the group.
