description: It is found that the X-Divertor (XD) configuration [1-3] can be made with the conventional PF coil set on ITER[4], where all PF coils are outside the TF coils. Desirable configurations are possible where the PF currents are below the present maximum design limits on ITER, and where the baseline divertor cassette is used. It is possible that the XD could be used to assist in high-power operation on ITER, but some further issues need examination. Note that the increased major radius of the Super X-Divertor (SXD) [5-8] is not a feature of the XD geometry. In addition, we present an XD configuration for K-DEMO [9], to demonstrate that it is also possible to attain the XD configuration in advanced tokamak reactors with all PF coils outside the TF coils. The results given here for the XD are far more encouraging than recent calculations by Lackner and Zohm [10] for the Snowflake [11,12], where the required high PF currents represent a major technological challenge. The magnetic field structure in the outboard divertor SOL [13] in the recently created XD configurations reproduces what was presented in the earlier XD papers [1-3]. Consequently, the same advantages accrue, but no close-in PF coils are employed.

description: Mobilding-hanke toteutettiin Lappeenrannan teknillisen yliopiston tietoliikennetekniikan laitoksella vuosien 2006 – 2008 aikana. Hankkeen alkuperäisenä tavoitteena oli selvittää, millä menetelmillä voidaan hallita rakennukseen liittyvät tiedot koko sen elinkaaren ajalta alkaen suunnittelusta, jatkuen läpi elementtivalmistuksen ja rakennusvaiheen sekä myöhemmin koko rakennuksen käyttöiän. Myöhemmin hankkeessa tehtiin kuitenkin elinkaaren osalta rajaus niin, että tarkasteltava elementtien elinkaari katsotaan alkavaksi rakennuksen suunnittelusta ja tarkasteltava elinkaari päättyy rakennuksen valmistumiseen, kun elementit ovat asennettu niille kuuluville paikoilleen ja jälkitarkastus on suoritettu.
Topological Soliton with Nonzero Hopf Invariant in Yang-Mills-Higgs Model

description: We propose a topological soliton or instanton solution with nonzero Hopf invariant to the 3+1D non-Abelian gauge theory coupled with scalar fields. This solution, which we call Hopf soliton, represents a spacetime event that makes a $2π$ rotation of the monopole. Although the action of this Hopf soliton is logarithmically divergent, it may still give relevant contributions in a finite-sized system. Since the Chern-Simons term for the unbroken $U(1)$ gauge field may appear in the low energy effective theory, the Hopf soliton may possibly generate fractional statistics for the monopoles.

title: Sitotroga cerealella (Olivier) resilience to extreme temperature and desiccation may explain its increasing pest status in changing climates

description: The mechanisms underlying Sitotroga cerealella survival under variable and increasing mean thermal and desiccation environments typical under global change is currently unknown. To understand how S. cerealella survives extreme abiotic stressors typical of stored-grain environments, we measured S. cerealella tolerance temperature and desiccation. The results showed that to survive desiccating grain storage environments, S. cerealella relied more on high body water content (BWC) (70.2 ± 3.72%) compared to lipid reserves (9.8± 0.81%). In desiccating environment, S. cerealella showed a reduced water loss rate (0.056mg/h) (equivalent of 1.81% of body water/hour) which would require 19.31 h to reduce the insect body water to its critical minimum (35.23% body water content at death), which is 50.20% of normal initial body water. Similarly S. cerealella exhibited high basal heat tolerance with critical thermal maximum of 46.09 ± 1.042°C and a heat knockdown time of 7.97 ± 1.64 minutes. Basal cold tolerance was relatively compromised (critical thermal minima of 4.52 ± 1.06°C and chill coma recovery time of 5.80 ±1.17 minutes), following 1h at 0°C. We found no significant correlation (P > 0.001) between BWC and the measured thermal tolerance traits. Low water loss rates reported here may be an evolutionary resistance mechanism for desiccation tolerance. Observed abiotic stress tolerance may explain the ubiquitous distribution of S. cerealella in Africa which is likely to enhance its survival and increase its pest status under global change.

description: Aims: A hard X-ray shortage, implying the cooling of the corona, was observed during bursts of IGR J17473-272, 4U 1636-536, Aql X-1, and GS 1826-238. Apart from these four sources, we investigate here an atoll sample, in which the number of bursts for each source is larger than 5, to explore the possible additional hard X-ray shortage during {\it Rossi X-ray timing explorer (RXTE)} era. Methods: According to the source catalog that shows type-I bursts, we analyzed all the available pointing observations of these sources carried out by the {\it RXTE} proportional counter array (PCA). We grouped and combined the bursts according to their outburst states and searched for the possible hard X-ray shortage while bursting. Results: We found that the island states of KS 1731-260 and 4U 1705-44 show a hard X-ray shortage at significant levels of 4.5 and 4.7 $σ$ and a systematic time lag of $0.9 \pm 2.1$ s and $2.5 \pm 2.0$ s with respect to the soft X-rays, respectively. While in their banana branches and other sources, we did not find any consistent shortage.

description: We investigate the mechanism to reproduce notable spectral features at the ignition phase of nova explosion observed for a super-Eddington X-ray transient source MAXI J0158$-$744 in the Small Magellanic Cloud. These are a strong Ne IX emission line at 0.92 keV with a large equivalent width of $0.32^{+0.21}_{-0.11}$ keV and the absence of Ne X line at 1.02 keV. In this paper, we calculate the radiative transfer using a Monte Carlo code, taking into account the line blanketing effect due to transitions of N, O, Ne, Mg and Al ions in an accelerating wind emanating from a white dwarf with a structure based on a spherically symmetric stationary model. We found that the strong Ne IX line can be reproduced if the mass fraction of Ne is enhanced to $10^{-3}$ or more and that of O is reduced to $\sim5\times10^{-9}$ or less and that the absence of other lines including Ne X ions at higher energies can be also reproduced by the line blanketing effect. This enhancement of the Ne mass fraction indicates that the ejecta are enriched by Ne dredged up from the surface of the white dwarf composed of O, Ne, and Mg rather than C and O, as already pointed out in the previous work. We argue that the CNO cycle driving this nova explosion converted most of C and O into N and thus reduced the O mass fraction.

Large laser-cooled samples of francium are produced from a francium ion beam delivered by the ISAC radioactive ion beam facility. The ion beam is neutralized on an yttrium foil, which is subsequently heated to transfer the atoms into the magneto-optical trapping region. We have successfully trapped $^{207}$Fr, $^{209}$Fr and $^{221}$Fr, with a maximum of $2.5 \times 10^5$ $^{209}$Fr atoms. The neutral cold atoms will be used in studies of the weak interaction through measurements of atomic parity non-conservation.

description: We have calculated the coherence and detectable lifetimes of synthetic near-Earth object (NEO) families created by catastrophic disruption of a progenitor as it suffers a very close Earth approach. The closest or slowest approaches yield the most violent `s-class' disruption events. We found that the average slope of the absolute magnitude (H) distribution, $N(H)\propto10^{(0.55\pm0.04)\,H}$, for the fragments in the s-class families is steeper than the slope of the NEO population \citep{mainzer2011} in the same size range. The families remain coherent as statistically significant clusters of orbits within the NEO population for an average of $\barτ_c = (14.7\pm0.6)\times10^3$ years after disruption. The s-class families are detectable with the techniques developed by \citet{fu2005} and \citet{Schunova2012} for an average duration ($\barτ_{det}$) ranging from about 2,000 to about 12,000 years for progenitors in the absolute magnitude ($H_p$) range from 20 to 13 corresponding to diameters in the range from about 0.5 to 10$\km$ respectively. The short detectability lifetime explains why zero NEO families have been discovered to-date. Nonetheless, every tidal disruption event of a progenitor with D$>0.5\km$ is capable of producing several million fragments in the $1\meter$ to $10\meter$ diameter range that can contribute to temporary local density enhancements of small NEOs in Earth's vicinity. We expect that there are about 1,200 objects in the steady state NEO population in this size range due to tidal disruption assuming that one $1\km$ diameter NEO tidally disrupts at Earth every 2,500 years. These objects may be suitable targets for asteroid retrieval missions due to their Earth-like orbits with corresponding low $v_{\infty}$. The fragments from the tidal disruptions at Earth have $\sim5\times$ the collision probability with Earth compared to the background NEO population.

description: Bei der Entwicklung eines Roboter Prototyps mit fünf Segmenten sind die Systemparameter zu identifizieren, die für den modellbasierten Regelungsentwurf notwendig sind. Die periodische Gehbewegung bei konstanter Geschwindigkeit wird durch die geregelten Schwingungen der Beine erzeugt. Das dynamische Experiment in Form eines Doppelpendels wird auf der Hälfte des Prototyps inklusive einem Oberschenkel und einem Unterschenkel durchgeführt. Die Rotationswinkel in der Hüfte- und Kniegelenke wird durch zwei Winkelsensoren aufgenommen. Das Parameteridentifikationsprocess wird als ein Homotopie-Methode basiertes Optimierungsproblem formuliert, das die Abweichung zwischen der gemessenen Zeitreihe und der simulierten Winkel-Trajektorie minimiert. Währenddessen werden die Anfangsbedingungen der Simulation, Sensorkalibrierung und Systemparameter variiert, bis ein globales Minimum erreicht ist. Die vorgestellte Methode zeigt eine zuverlässige und reproduzierbare Abschätzung der Parameter auf das reale System.

description: We study the semileptonic decays of $B^-\to f_0(1710\,,1500\,,1370) e^-\bar ν_e$, in which the three $f_0$ states mix with glueball, $\bar s s$ and $(\bar u u+\bar d d)/\sqrt 2$ states, respectively. By averaging the mixings fitted in the literature, we find that the branching ratios of $B^-\to f_0 e^-\bar ν_e$ are $O(10^{-6})$, $O(10^{-6})$ and $O(10^{-5})$, respectively, which can be simultaneously observed in experiments at $B$ factories. The large predicted branching rate for $B^-\to f_0(1370) e^-\bar ν_e$ would provide a clean mode to directly observe the $f_0(1370)$ state.

description: We discuss the appearance of fractional topological phases on cyclic evolutions of entangled qudits. The original result reported in Phys. Rev. Lett. \textbf{106}, 240503 (2011) is detailed and extended to qudits of different dimensions. The topological nature of the phase evolution and its restriction to fractional values are related to both the structure of the projective space of states and entanglement. For maximally entangled states of qudits with the same Hilbert space dimension, the fractional geometric phases are the only ones attainable under local SU($d$) operations, an effect that can be experimentally observed through conditional interference.

description: We present an analysis of a ~160 ks NuSTAR observation of the nearby bright Seyfert galaxy IC4329A. The high-quality broadband spectrum enables us to separate the effects of distant reflection from the direct coronal continuum, and to therefore accurately measure the high-energy cutoff to be $E_{cut}=178^{+74}_{-40}$ keV. The coronal emission arises from accretion disk photons Compton up-scattered by a thermal plasma, with the spectral index and cutoff being due to a combination of the finite plasma temperature and optical depth. Applying standard Comptonization models, we measure both physical properties independently using the best signal-to-noise obtained to date in an AGN over the 3-79 keV band. We derive $kT_e=37^{+7}_{-6}$ keV with $τ=1.25^{+0.20}_{-0.10}$ assuming a slab geometry for the plasma, and $kT_e=33^{+6}_{-6}$ keV with $τ=3.41^{+0.58}_{-0.38}$ for a spherical geometry, with both having an equivalent goodness-of-fit.

Weak turbulence theory for rotating magnetohydrodynamics and planetary dynamos
Creators: name: Galtier, Sebastien
Publisher: name: arXiv
Year: 2014
Subjects: subject: Geophysics (physics.geo-ph)
subject: FOS: Physical sciences

description: A weak turbulence theory is derived for magnetohydrodynamics under rapid rotation and in the presence of a large-scale magnetic field. The angular velocity $Ω_0$ is assumed to be uniform and parallel to the constant Alfvén speed ${\bf b_0}$. Such a system exhibits left and right circularly polarized waves which can be obtained by introducing the magneto-inertial length $d \equiv b_0/Ω_0$. In the large-scale limit ($kd \to 0$; $k$ being the wave number), the left- and right-handed waves tend respectively to the inertial and magnetostrophic waves whereas in the small-scale limit ($kd \to + \infty$) pure Alfvén waves are recovered. By using a complex helicity decomposition, the asymptotic weak turbulence equations are derived which describe the long-time behavior of weakly dispersive interacting waves {\it via} three-wave interaction processes. It is shown that the nonlinear dynamics is mainly anisotropic with a stronger transfer perpendicular ($\perp$) than parallel ($\parallel$) to the rotating axis. The general theory may converge to pure weak inertial/magnetostrophic or Alfvén wave turbulence when the large or small-scales limits are taken respectively. Inertial wave turbulence is asymptotically dominated by the kinetic energy/helicity whereas the magnetostrophic wave turbulence is dominated by the magnetic energy/helicity. For both regimes a family of exact solutions are found for the spectra which do not correspond necessarily to a maximal helicity state. It is shown that the hybrid helicity exhibits a cascade whose direction may vary according to the scale $k_f$ at which the helicity flux is injected with an inverse cascade if $k_fd < 1$ and a direct cascade otherwise. The theory is relevant for the magnetostrophic dynamo whose main applications are the Earth and giant planets for which a small ($\sim 10^{-6}$) Rossby number is expected.

description: Mid-infrared (MIR) quasar spectra exhibit a suite of emission features including high ionization coronal lines from the narrow line region (NLR) illuminated by the ionizing continuum, and hot dust features from grains, as well as polycyclic aromatic hydrocarbons (PAH) features from star formation in the host galaxy. Few features are detected in most spectra because of typically low signal-to-noise ratio (S/N) data. By generating spectral composites in three different luminosity bins from over 180 Spitzer Infrared Spectrograph (IRS) observations, we boost the S/N and reveal important features in the complex spectra. We detect high-ionization, forbidden emission lines in all templates, PAH features in all but the most luminous objects, and broad silicate and graphite features in emission whose strength increases relative to the continuum with luminosity. We find that the intrinsic quasar spectrum for all luminosity templates is consistent, and the differences in the spectra can be explained by host galaxy contamination in the lower luminosity templates. We also posit that star formation may be active in most quasar host galaxies, but the spectral features of star formation are only detectable if the quasar is faint.

description: It can be shown on observational grounds that two basic effects of dynamo theory for solar activity - production of the toroidal field from the poloidal one by differential rotation and reverse conversion of the toroidal field to the poloidal configuration by helical motions - are operating in the Sun. These two effects, however, do not suffice for constructing a realistic model for the solar dynamo. Only when a non-local version of the alpha-effect is applied, is downward diamagnetic pumping included and field advection by the equatorward meridional flow near the base of the convection zone allowed for, can the observed activity cycles be closely reproduced. Fluctuations in the alpha-effect can be estimated from sunspot data. Dynamo models with fluctuating parameters reproduce irregularities of solar cycles including the grand activity minima. The physics of parametric excitation of irregularities remains, however, to be understood.

description: GaAs and GaAs based materials have outstanding optoelectronic properties and are widely used as light emitting media in devices. Many approaches have been applied to GaAs to generate luminescence at 0.88, 1.30, 1.55 um which are transmission windows of optical fibers. In this paper we present the photoluminescence at 1.30 um from deep level defects in GaAs treated by ion-implantation and flash lamp annealing (FLA). Such emission, which exhibits superior temperature stability, can be obtained from FLA treated virgin GaAs as well as doped GaAs. Indium-doping in GaAs can greatly enhance the luminescence. By photoluminescence, Raman measurements, and positron annihilation spectroscopy, we conclude that the origin of the 1.30 um emission is from transitions between the VAs-donor and X-acceptor pairs.

description: The lesser grain borer, Rhyzopertha dominica, and red flour beetle, Tribolium castaneum, are two notorious primary and secondary pests of stored products. Extensive research has been done to prevent the establishment and subsequent infestation of the insects in stored product facilities. Long-lasting insecticide netting (LLIN) on mosquitoes has proved effective in controlling the spread of malaria, but little research has been conducted on the LLIN’s behavioral effects of stored product insects. In this study, a movement and dispersal assay were performed. In the movement assay, the video-tracking software, Ethovision, recorded the movement of R. dominica and T. castaneum after 1-10 min exposures to LLIN or control netting and a waiting period of 1 min, 24 hr, 72 hr, or 7 days after netting exposure. In the dispersal assay, R. dominica and T. castaneum were observed after 5 minutes of exposure to LLIN or control netting to measure the insects’ ability to reach new food patches at three different distances. The results from the movement assay showed a significant reduction in horizontal movement and significant increase in angular velocity for beetles exposed to LLINs, indicating that movements were more erratic and less directed. The dispersal assay revealed that exposure to LLIN had a significant effect on the dispersal ability of both R. dominica and T. castaneum with averages of 0-3 from a group of 20 beetles reaching the new food patch. These results indicate that LLINs can be an effective tool for the prevention of stored product insect establishment and colonization.

description: Pancreatic ductal adenocarcinoma (PDAC) is a devastating disease with a dismal outcome. To improve understanding of sequential microbiome changes during PDAC development we analyzed mouse models of pancreatic carcinogenesis (KC mice recapitulating pre-invasive PanIN formation, as well as KPC mice recapitulating invasive PDAC) during early tumor development and subsequent tumor progression. Diversity and community composition were analyzed depending on genotype, age, and gender. Both mouse models demonstrated concordant abundance changes of several genera influenced by one or more of the investigated factors. Abundance was significantly impacted by gender, highlighting the need to further elucidate the impact of gender differences. The findings underline the importance of the microbiome in PDAC development and indicate that microbiological screening of patients at risk and targeting the microbiome in PDAC development may be feasible in future.

description: Late-onset Alzheimer disease (LOAD) is the most frequent neurodegenerative disease, and the APOE ε4 allele is the most prominent risk factor for LOAD. Four human induced pluripotent stem cell (iPSC) lines MLUi007-J, MLUi008-B, MLUi009-A, and MLUi010-B were generated from LOAD patients and healthy matched donors by reprogramming of B-lymphoblastoid cells (B-LCLs) with episomal plasmids. The application of B-LCLs holds a great promise to model LOAD and other diseases because they can easily be generated from primary peripheral blood mononuclear cells (PBMCs) by infection with the Epstein-Barr virus (EBV).
Gammoids, Pseudomodularity and Flatness Degree

description: We study weaker variations of the property of flatness in matroid theory. We show that these variations form a chain of increasingly stronger properties all implying pseudomodularity on its lattice of flats. We show examples in the gammoid class that show that these properties are in fact different.

description: Open access publishing - and open research more broadly - expands the opportunities for researchers to share their research more widely and rapidly than ever before. By sharing work in more open and discoverable ways, researchers can build their networks and collaborations and be part of a more constructive, transparent and effective research culture and bring benefits to the whole research system. Join Carolyn Kirby, Director of Open Research at Taylor & Francis, and Becky Hill, Strategic Partnership Manager at F1000, for an overview and discussion of how open research publishing practices can help researchers to enhance the discoverability and potential impact of their research. We will provide evidence of the growing appetite for open access publishing from across the region, and introduce a range of publishing options, spearheaded by F1000, to help enable open research. Focusing on publishing practices which place openness at their centre, including topics such as open data, diversity of research outputs and open community peer review, this session will bring together the evolution of the market landscape with applied experiences of open research publishing. Session attendees will learn more about F1000 and its publishing approach, as well as being invited to ask questions, debate and share their views on all things open.

description: We analyze one particle, two-center quantum problems which admit separation of variables in prolate spheroidal coordinates, a natural restriction satisfied by the H$_2^+$ molecular ion. The symmetry operator is constructed explicitly. We give the details of the Hamiltonian reduction of the 3D system to a 2D system with modified potential that is separable in elliptic coordinates. The potentials for which there is double-periodicity of the Schrödinger operator in the space of prolate spheroidal coordinates, including one for the H$_2^+$ molecular ion, are indicated. We study possible potentials that admit exact-solvability is as well as all models known to us with the (quasi)-exact-solvability property for the separation equations. We find deep connections between second-order superintegrable and conformally superintegrable systems and these tractable problems. In particular we derive a general 4-parameter expression for a model potential that is always integrable and is conformally superintegrable for some parameter choices.

Three-Point Functions and su(1|1) Spin Chains

subject: FOS: Physical sciences

description: We compute three-point functions of general operators in the su(1|1) sector of planar N = 4 SYM in the weak coupling regime, both at tree-level and one-loop. Each operator is represented by a closed spin chain Bethe state characterized by a set of momenta parameterizing the fermionic excitations. At one-loop, we calculate both the two-loop Bethe eigenstates and the relevant Feynman diagrams for the three-point functions within our setup. The final expression for the structure constants is surprisingly simple and hints at a possible form factor based approach yet to be unveiled.

title:  How Do Personal Connections Play a Role in Risk Perception of Climate Change and Sea Level Rise?
Creators: name: Sheeley, Katelyn
Publisher: name: Old Dominion University Libraries

description: The threat of sea level rise is unknown to many coastal residents living in the United States, including Virginians. Climate Central, a nonprofit research-based organization, has created the Risk Finder tool to help inform the public about the potential dangers posed by sea level rise. Risk Finder is an interactive, online mapping tool intended to inform residents of useful data concerning sea level rise. Dr. Daniel Richards and Mrs. Megan Mckittrick from Old Dominion University acted as primary investigators for a study of the Risk Finder tool, serving client Dan Rizza of Climate Central. Students of ENGL 231C served as secondary investigators for observation and transcription of results. This civic learning project consists of usability testing conducted on Climate Central’s new Risk Finder tool. Investigators of this project reached out to residents of Hampton Roads via informational flyers to request participation in the research study and the survey questionnaires following. Research sessions were conducted with a total of 8-10 participants, an ample sample size for this type of research. Participants were interviewed before and after they used the Climate Central website, and were observed in their unstructured use of the Risk Finder tool for the allotted time. These usability tests serve the client, Dan Rizza, by providing useful feedback to Climate Central, including potential enhancements to make the Risk Finder tool more efficient and useful for the public. Results from this research help researchers in the field of study to better understand methods to communicate information on sea level rise to citizens in a way that connects with the public.

description: We describe our approach to atomic magnetometry based on the push-pull optical pumping technique. Cesium vapor is pumped and probed by a resonant laser beam whose circular polarization is modulated synchronously with the spin evolution dynamics induced by a static magnetic field. The magnetometer is operated in a phase-locked loop, and it has an intrinsic sensitivity below 20fT/\sqrt(Hz) using a room temperature paraffin-coated cell. We use the magnetometer to monitor magnetic field fluctuations with a sensitivity of 300fT/\sqrt(Hz).

description: Bhutan is a part of the second-largest Tiger Conservation Landscape (TCL), The Northern Forest Complex-Namdapha-Royal Manas, and is home to a tiger population of global conservation priority. With its well-connected protected area network and a vast expanse of forested landscape, Bhutan has a unique potential to spatially connect tiger populations in the Terai TCL of India and Nepal on the western side to the north-eastern part of the Indian subcontinent. However, information on genetic structure and connectivity among tiger populations is lacking in the Eastern Himalayan region. Due to the large and contiguous forested landscape with a network of well-connected protected areas and strong environmental protection measures in Bhutan, tiger populations in Bhutan are expected to have high genetic variation and gene flow. We made the first-ever attempt at the genetic sampling of the tiger population in Bhutan, where we genotyped 24 tiger individuals using thirteen microsatellite loci. Genetic analyses revealed three genetic clusters and found high expected heterozygosity (mean HE = 0.73) and moderate-to-high genetic differentiation (FST = 0.135) within this pool of sampled tigers. We also were able to assign poached tigers to our inferred genetic clusters. Two individual wild tigers showed distinct multilocus genotypes, similar to each other but highly divergent from all other sampled tigers, suggesting their origin from outside the sampled areas. Our study provides the first insights into the population genetic structure of tigers in this important region and suggests that gene flow is less than suggested by dispersal. A larger landscape-level genetic study with implications for the transboundary conservation of tigers in this highly biodiverse landscape is warranted.

description: Elucidating contents and drivers of soil bacterial and fungal biomass in contrasting land uses and climates at European scale is useful to define appropriate policies for the conservation of the ecosystem services that soil microorganisms provide. Here, we aimed to (i) quantify and compare bacterial and fungal biomass in 513 European soils collected from three different land uses (forests, grasslands, and croplands) and climates (arid, temperate, and cold) through analysis of fatty acid methyl esters; (ii) model the factors controlling soil bacterial and fungal biomass; and (iii) investigating levels of bacterial and fungal biomass in cropland soils cultivated with three important crop types in Europe: cereals, oil-producing crops, and orchards. Bacterial biomass decreased with land use in the following order: grasslands > croplands > forests and was found to be the highest in temperate environments. Similar patterns were found for biomass of Gram-positive and Gram-negative bacteria and Actinobacteria. Soil fungal biomass was greater in forests than in croplands and grasslands and was favoured by colder environments. The fungi to bacteria ratio (F/B) decreased as follows: forests > croplands > grasslands, with soils in colder climates showing greater F/B ratios in croplands and forests. Soil texture, soil organic carbon, and nitrogen were shown to directly drive bacterial and fungal biomass. The biomass of the different microbial groups was not influenced by the crop type when only croplands were considered. Fungi appear to be more susceptible to agricultural soil use than bacteria. Moreover, agricultural use of soil seems to buffer the effect of harsh climatic conditions on soil bacterial biomass. The present study improves our understanding of the combined effects of land use and climate on soil bacterial and fungal biomass across Europe.

description: We present a comprehensive structural characterization of ferromagnetic SiC single crystals induced by Ne ion irradiation. The ferromagnetism has been confirmed by electron spin resonance and possible transition metal impurities can be excluded to be the origin of the observed ferromagnetism. Using X-ray diffraction and Rutherford backscattering/channeling spectroscopy, we estimate the damage to the crystallinity of SiC which mutually influences the ferromagnetism in SiC.

description: The Berry curvature in Chern insulators appears to be a non-gauge-invariant quantity and does not immediately allow local length characterization. However, in two examples of 2- and 3-band models that we discuss, we find high-symmetry points in the Brillouin zone that have Berry curvature invariant under diagonal gauge transformations, and may serve as expansion points of geometrical description. On the basis of the geometrical description, in the case of Dirac based 2-band Chern insulators like Haldane model we conclude that the characteristic length based on the value of the Berry curvature at the expansion point plays the role of the magnetic length in the expression for the Hall viscosity. In the case of 2-band models the characteristic "cyclotron" spin is equal to 1/2, while in the 3-band kagome case this spin is likely non-quantized and non-universal.
