Creators: name: (:Unkn) Unknown
Publisher: name: Zürich : EMS Publ. House
Year: 2021
Subjects: subject: Konferenzschrift
subject: 510

description: The consideration of wave propagation in inhomogeneous media or the modelling of nonlinear waves often requires the study of wave equations with low regularity data and/or coefficients. Several Australian-European collaborations have recently led to deeper analytical understanding of rough wave equations. This tandem workshop provided a platform for such collaborations and brought together early career researchers and leading experts in harmonic analysis, microlocal analysis and spectral theory. The workshop focused on collaboration and technical knowledge exchange on topics such as local smoothing, spectral multipliers, restriction estimates, Hardy spaces for Fourier integral operators, and nonlinear partial differential equations.
Water Solubility in Fe‐Bearing Wadsleyite at Mantle Transition Zone Temperatures
Creators: name: Fei, Hongzhan
name: Katsura, Tomoo
Publisher: name: FID GEO
Year: 2021

description: Wadsleyite can store significant amounts of H2O in its crystal structure as hydroxyl. However, H2O solubility in Fe‐bearing wadsleyite remains poorly constrained at mantle transition zone temperatures. Previous studies (e.g., Demouchy et al., 2005 [https://doi.org/10.2138/am.2005.1751]; Litasov et al., 2011 [https://doi.org/10.1007/s00269-010-0382-3]) focused primarily on Fe‐free systems, which do not represent the Earth's interior because Fe may affect the H2O solubility. Here, we investigated the temperature dependence of H2O solubility in Fe‐bearing and Fe‐free wadsleyite at 1500–2100 K. The results indicate that H2O solubility in Fe‐bearing wadsleyite is higher than in Fe‐free samples at 1800–1900 K, corresponding to transition zone geotherm, but there is no clear Fe content dependence in the Fe‐bearing samples. Wadsleyite can contain approximately 1.0 wt.% H2O at transition zone temperatures. The H2O solubility in wadsleyite is lower than ringwoodite along a plume geotherm, which may result in dehydration melting at the 520‐km discontinuity by upwelling flow in plumes.
description: Plain Language Summary: The mantle transition zone at 410–660 km depth is a H2O sponge because wadsleyite and ringwoodite can contain large amounts of H2O in their crystal structures as hydroxyl defects. However, the solubility of H2O in Fe‐bearing wadsleyite is poorly constrained compared with ringwoodite and Fe‐free wadsleyite, which have been extensively investigated. The exact H2O storage capacity of the mantle transition zone, therefore, remains unknown. Here, we investigated the solubility of H2O in Fe‐bearing wadsleyite as a function of temperature. The results indicate that wadsleyite can store ∼1.0 wt.% H2O at transition zone temperatures and ∼0.65 wt.% along a plume geotherm. H2O solubility in wadsleyite is lower than that in ringwoodite in mantle plumes. A dehydration melting layer at the 520‐km discontinuity near plumes can, therefore, form via the phase transition from ringwoodite to wadsleyite under H2O‐saturated conditions driven by upwelling flow in mantle plumes.
description: Key Points: H2O solubility in Fe‐bearing wadsleyite decreases with increasing temperature. Fe‐bearing wadsleyite can contain ∼1.0 wt.% H2O at mantle transition zone temperature. Dehydration melting could occur at the 520‐km discontinuity by upwelling flow near plumes.

description: This working paper presents the findings of the empirical research on the role of connectivity and mobility for displaced people in Germany in the framework of the TRAFIG project. The findings are based on qualitative fieldwork in Germany, with 73 qualitative interviews with displaced people and experts in the field. This paper uses a figurational perspective; figurations are characterised as dynamic social constellations which emerge in the context of displacement between displaced people and state and other actors at the local, translocal and transnational scale. This working paper discusses the figurations of displacement in which refugees in Germany are embedded. Our analysis demonstrates the importance of family figurations in displacement, among them the “figuration of a transnationally separated family”, “figuration of the jointly displaced family”, or the “figuration of the transnationally extended family”. Family figurations are deeply intertwined with local and transnational bureaucratic figurations, which structure the experiences of refugees. Bureaucratic figurations evolve with respect to German authorities, those of the countries of origin and other local actors. Despite the significance of family figurations, connectivity is not restricted to it. Refugees are also connected within non-kin figurations, such as within an “ethnic network-based” or “volunteer-refugee” figuration. The analytical category of figurations provides valuable insights into how displaced people embedded in certain social constellations can best be supported. It shows that transnational life is a reality for displaced persons and an integral part of their everyday lives. As the German case demonstrates, displaced people use mobility and connectivity as a way out of protracted displacement.

Boundary Element Methods

Subjects: subject: Konferenzschrift
subject: 510

description: The field of boundary element methods (BEM) relies on recasting boundary value problems for (mostly linear) partial differential equations as (usually singular) integral equations on boundaries of domains or interfaces. Its main goal is the design and analysis of methods and algorithms for the stable and accurate discretization of these integral equations, the data-sparse representation of the resulting systems of equations, and their efficient direct or iterative solution. Boundary element methods play a key role in important areas of computational engineering and physics addressing simulations in acoustics, electromagnetics, and elasticity. Thus progress in boundary element method, both theoretical and algorithmic, is definitely relevant beyond mathematics. Boundary element methods had been developed for many decades, but during the past two decades the field has seen a surge in research activity, spurred by algorithmic and theoretical breakthroughs concerning BEM for electromagnetics, time-domain methods, new approaches to eigenvalue problems, adaptivity, local low-rank matrix compression, and frequency-explicit analysis, to name only a few. The contributions in this report give an impressive panorama of the many and diverse current research activities in BEM. They range profound mathematical analyses with striking results to new algorithmic developments. On the one hand, the results are based on a large variety of tools from many areas of mathematics. On the other hand, research in BEM blazes the trail for progress in the numerical treatment of non-local operators, a field that is rapidly gaining importance.

description: In the framework of the instanton vacuum model we evaluate the Chiral Perturbation Theory (ChPT) low-energy constants h_3,l_7. We found that in the instanton vacuum model the constant l_7 is very sensitive to the shape of the instanton and the instanton vacuum parameters. We evaluated the constant l_7 for two different zero-mode profiles and as a function of the average instanton size ρand inter-instanton distance R. Our result agrees with an old "order of magnitude" estimate of this constant from [1]. The obtained value of l_7 implies that the pure QCD contribution to the pion mass difference is small, ~1% of the observed experimental value.

Interacting new agegraphic dark energy in non-flat Brans-Dicke cosmology

Year: 2009
Subjects: subject: General Relativity and Quantum Cosmology (gr-qc)

description: We construct a cosmological model of late acceleration based on the new agegraphic dark energy model in the framework of Brans-Dicke cosmology where the new agegraphic energy density $ρ_{D}= 3n^2 m^2_p /η^{2}$ is replaced with $ρ_{D}= {3n^2ϕ^2}/({4ωη^2}$). We show that the combination of Brans-Dicke field and agegraphic dark energy can accommodate $w_D = -1 $ crossing for the equation of state of \textit{noninteracting} dark energy. When an interaction between dark energy and dark matter is taken into account, the transition of $w_D $ to phantom regime can be more easily accounted for than when resort to the Einstein field equations is made. In the limiting case $α= 0$ $(ω\to \infty)$, all previous results of the new agegraphic dark energy in Einstein gravity are restored.

Stimulus properties : perceptual learning and their effect on disappearances of luminous figures
Creators: name: Creighton, Terence Donald
Publisher: name: University of British Columbia
Year: 2011

description: Subjects viewed luminous targets in a dark room. Target size and composition were varied to determine their effect on subjects' reports of complete figure disappearances. The number of complete target disappearances decreased as the size of the retinal image increased. Fragmentations related to meaning and shape were also greatest under viewing conditions involving small retinal images. Subjects showed no preference when they were given the opportunity to respond to either shape of conceptual similarities in the target. Prior perceptual learning experiences were also varied. Evidence for perceptual learning on a specific target (PPL) was not found with subjects who reported that they had astigmatism. Perceptual learning was demonstrated using either a within-S or between-S design, and was found to decay rapidly over time. More meaningful training stimuli produced a greater degree of learning. Evidence for stimulus generalization was also found using a perceptual learning exercise.

A Comparison of the Location of the Mid‐Latitude Trough and Plasmapause Boundary
Creators: name: Weygand, J. M.

Year: 2021

description: Abstract: We have compared the location of the mid‐latitude trough observed in two dimensional vertical total electron content (vTEC) maps with four plasmapause boundary models, Radiation Belt Storm Probes (RBSP) observations, and IMAGE extreme ultraviolet (EUV) observations all mapped to the ionosphere pierce point using the Tsyganenko (1996) magnetic field line model. For this study, we examine four events over North America: one just after the October 13, 2012 storm, one during the April 20, 2002 double storm, another during a large substorm on January 26, 2013, and one quiet event on May 19, 2001. We have found that in general, the equatorward edge of the mid‐latitude trough is within several degrees in geographic latitude of the mapped model plasmapause boundary location, the plasmapause boundary identified with IMAGE EUV, and the location identified by the RBSP spacecraft. When the mid‐latitude trough is mapped to the inner magnetosphere, the observed boundary agrees with the plasmapause boundary models within two Earth Radii at nearly all local times in the nightside and the observed mid‐latitude boundary is within the uncertainty of the observations at most local times in the nightside. Furthermore, during dynamic solar wind conditions of April 20, 2002, the mid‐latitude trough observed in the vTEC maps propagates equatorward as the plasmapause boundary identified with IMAGE EUV moves earthward. Our results indicate that the mid‐latitude trough observed within the vTEC maps represents an additional means of identifying the plasmapause boundary location, which could result in improved plasmapause boundary models.
description: Plain Language Summary: The equatorward edge of the mid‐latitude trough as observed in TEC maps indicates the location of the plasmapause boundary. We compare the location of the mid‐latitude trough for four events over a range of geomagnetic conditions with plasmapause boundary identified by IMAGE extreme ultraviolet and Radiation Belt Storm Probes and the plasmapause location as indicated by four different models. We find a good agreement between some the methods even under dynamics conditions. The mid‐latitude trough can supply the location for the plasmapause boundary during periods when no spacecraft are available to identify the boundary.
description: Key Points: We show for a range of geomagnetic conditions that the locations of the mid‐latitude trough observed in vTEC maps and IMAGE EUV measured plasmapause boundary mapped with a magnetic field line model to the ionosphere generally agree within the uncertainty. We show that common models of the position of the plasmapause boundary mapped with a magnetic field line model to the ionosphere generally agree with the location of the mid‐latitude trough.

description: We consider the adjacency matrix $A$ of a large random graph and study fluctuations of the function $f_n(z,u)=\frac{1}{n}\sum_{k=1}^n\exp\{-uG_{kk}(z)\}$ with $G(z)=(z-iA)^{-1}$. We prove that the moments of fluctuations normalized by $n^{-1/2}$ in the limit $n\to\infty$ satisfy the Wick relations for the Gaussian random variables. This allows us to prove central limit theorem for $\hbox{Tr}G(z)$ and then extend the result on the linear eigenvalue statistics $\hbox{Tr}ϕ(A)$ of any function $ϕ:\mathbb{R}\to\mathbb{R}$ which increases, together with its first two derivatives, at infinity not faster than an exponential.

description: The computation of the domination-type parameters is a challenging problem in Cartesian product graphs. We present an algorithmic method to compute the $2$-domination number of the Cartesian product of a path with small order and any cycle, involving the $(\min,+)$ matrix product. We establish some theoretical results that provide the algorithms necessary to compute that parameter, and the main challenge to run such algorithms comes from the large size of the matrices used, which makes it necessary to improve the techniques to handle these objects. We analyze the performance of the algorithms on modern multicore CPUs and on GPUs and we show the advantages over the sequential implementation. The use of these platforms allows us to compute the $2$-domination number of cylinders such that their paths have at most $12$ vertices.
Nurses and constructions of motherhood: 'scientific motherhood' and the rise of child welfare services in Tasmania 1918-1930
Creators: name: Brennan, SN
Publisher: name: University Of Tasmania
Year: 2023

description: Motherhood is a momentous life-change for women. While commonalities of experience exist between women, each woman's experience is unique. Social constructions define motherhood in particular ways and in doing so tend to deny the range and complexity of individual experience. In recent decades a wide body of feminist and other literature has developed which analyses the way motherhood has been historically constructed and what this means for women. This thesis concentrates upon the ways in which early twentieth century Australians, in common with their counterparts in North America, New Zealand and the United Kingdom, constructed 'scientific motherhood'. The perspective and method of history are used in this work to explore the construction of scientific motherhood. In particular, the establishment of the Tasmanian Child Welfare Service is examined, for the origins of this service are closely linked to the requirement that information be disseminated throughout the population about modem 'scientific' mothering. Therefore, this thesis looks at the historical development of this service, at how it grew out of a late 19th century veneration of science as well as concerns regarding population and the position of women in society. It shows the influences lying behind the construction of motherhood as a science and outlines the art played by child health services in bringing this new, as it was perceived at the time, view of rational and efficient mothering to women.

description: Statistics for stochastic differential equations (SDEs) attempts to use SDEs as statistical models for real-world phenomena. This involves an understanding of qualitative properties of this class of stochastic processes which includes Brownian motion as well as estimation of parameters in the SDE or a nonparametric estimation of drift and diffusivity fields from observations. Observations can be in continuous time, in high frequency discrete time considering the limit of small inter-observation times or in discrete time with constant inter-obseration times. Application areas of SDEs where state spaces are naturally viewed as manifolds or stratified spaces include multivariate stochastic volatility models, stochastic evolution of shapes (e.g. of biological cells), time-varying image deformations for video analysis and phylogenetic trees.

description: The Shanxi rift is located in the central part of the North China Craton (NCC). With strong tectonic deformation and intense seismic activity, its crust‐mantle deformation and deep structure have always attracted wide attention. Using teleseismic events observed in a dense network of 610 temporary and 127 permanent stations in the central NCC, we obtained the crust‐mantle S wave velocity structures by the joint inversion method of receiver functions and surface wave dispersion data. Our results show that the crust thickens in the northern part of the Shanxi rift (41 km) and thins in the southern part (35 km). The Taiyuan and Linfen basins, located in the central part, have high‐velocity zones in the lower crust and upper mantle; beneath the Yuncheng basin in the south, there are low‐velocity zones in the lower crust and uppermost mantle (30–80 km); the Datong basin, located in the northern part of the rift, exhibits a wide range of low‐velocity anomalies in the middle to lower crust and upper mantle. We speculate that the destruction of the NCC and associated lithospheric thinning had a significant impact on the southern part of the rift, but is still in its early stage in the central part, which retains most of the craton features. An upwelling of the asthenospheric magma occurred beneath the western part of the Datong basin. The horizontal deflection of the asthenospheric flow causes low‐velocity anomalies in its surrounding area, which is consistent with LAB topography.
description: Key Points: A more detailed crustal thickness and S wave velocity structure from joint inversion of receiver function and surface wave dispersion. The destructions of the North China Craton have different effects on the central and southern parts of the Shanxi rift. The velocity structure beneath northern Shanxi rift is mainly controlled by the asthenospheric magma flow.

description: Screening of Coulomb field of test charge in plasma with Bose condensate of electrically charged scalar field is considered. It is found that the screened potential contains several different terms: one decreases as a power of distance (in contrast to the usual exponential Debye screening), some other oscillate with an exponentially decreasing envelope. Similar phenomenon exists for fermions (Friedel oscillations), but fermionic and bosonic systems have quite different features. Several limiting cases and values of the parameters are considered and the resulting potentials are presented.

The standard of medical care in Malaysia : the case for legislative reform
Creators: name: Lee, JMY
Publisher: name: University Of Tasmania
Year: 2023

description: This thesis analyses the law relating to the standard of care expected of doctors in the areas of diagnosis and treatment in Malaysia. The analysis does not deal with issues concerning disclosure of risk. The central argument in this thesis is that the law for determining the standard of care of doctors in the areas of diagnosis and treatment in Malaysia is ambiguous and uncertain, and that legislation is the most effective reform method to resolve these problems. A clear and predictable legal framework is recommended for legislative enactment in Malaysia. One of the main objectives of this proposed legal framework is to strike a balance between the interests of defendant doctors and that of injured patients in medical negligence litigation concerning issues of diagnosis and treatment. This thesis traces the historical development of the law in Malaysia, from the application of the original English Bolam test in the 1960s to the current legal position as decided by the highest Malaysian court decision in Foo Fio Na v Dr Soo Fook Mun (2007) 1 MLJ 593. It takes a cross-jurisdictional approach to examine the corresponding legal development in the United Kingdom, Singapore and the Australian states. A consistent trend in these jurisdictions is the adoption of the original Bolam test with modifications, albeit in different forms. It is argued that the decision in Foo Fio Na was a lost opportunity for the highest Malaysian court to give a definitive statement for determining the standard of care in the areas of medical diagnosis and treatment. The basis for this argument is the ambiguity in Foo Fio Na on the issue of negligent treatment and the conflicting interpretations of this decision by academic scholars and judges in subsequent Malaysian lower court cases. It is proposed that Malaysia should codify the qualified version of the Bolam test in legislation as a means of resolving the uncertainty and ambiguity in the current state of the law. It is also suggested that the proposed legislation should implement the procedural rules on the use of expert witnesses similar to those under the Uniform Civil Procedure Rules 1999 (Qld), although with slight modifications. The proposed procedural framework requires the appointment of a single agreed or a single court-appointed expert prior to the commencement of legal proceedings. Litigants may also appoint an additional agreed or court-appointed expert or experts after legal proceedings have started. Under the proposal, the courts are also given the authority to allow litigants to engage their own medical experts provided that certain conditions are satisfied. These recommendations aim to save costs, facilitate a speedy resolution of medical disputes and provide flexibility in the adjudication of the standard of care in medical diagnosis and treatment.

The triple is based on a countable set of oriented graphs and the algebra consists of generalized holonomy loops in this set. The Dirac type operator resembles a global functional derivation operator and the interaction between the algebra of holonomy loops and the Dirac type operator reproduces the structure of a quantized Poisson bracket of general relativity. Finally we give a heuristic argument as to how a natural candidate for a quantized Hamiltonian might emerge from this spectral triple construction.

description: The central topic of the workshop was the notion of logarithmic vector fields along a divisor in a smooth complex analytic or algebraic variety, i.e., the vector fields on the ambient variety tangent to the divisor. Following their introduction by K.~Saito for the purpose of studying the universal unfolding of an isolated singularity, this fundamental object has been the focus of studies in a wide range of mathematical fields such as algebra, algebraic geometry, singularity theory, root systems, (geometric) representation theory, combinatorics, (toric) topology, or symplectic geometry. In the last few years the logarithmic vector field approach has seen some unexpected and striking advances and deep applications. The aim of the workshop was to provide reports and to share these various new developments in the field.

description: The efficiency of sediment routing from land to the ocean depends on the position of submarine canyon heads with regard to terrestrial sediment sources. We aim to identify the main controls on whether a submarine canyon head remains connected to terrestrial sediment input during Holocene sea‐level rise. Globally, we identified 798 canyon heads that are currently located at the 120m‐depth contour (the Last Glacial Maximum shoreline) and 183 canyon heads that are connected to the shore (within a distance of 6 km) during the present‐day highstand. Regional hotspots of shore‐connected canyons are the Mediterranean active margin and the Pacific coast of Central and South America. We used 34 terrestrial and marine predictor variables to predict shore‐connected canyon occurrence using Bayesian regression. Our analysis shows that steep and narrow shelves facilitate canyon‐head connectivity to the shore. Moreover, shore‐connected canyons occur preferentially along active margins characterized by resistant bedrock and high river‐water discharge.
description: Plain Language Summary: Since the last glaciation about 20,000 years ago, sea level has risen by about 120 m. As a consequence, most coastlines have migrated landward, inundating large shelf areas. Some of these areas are now dissected by submarine canyons. However, with only 4% of the world’s submarine canyons reaching today's coastline, these canyons remain the exception. Here, we aim to identify the environmental factors and processes that control whether rates of headward canyon incision can keep pace with landward migration of the coastline during the Holocene. We determine 34 variables that potentially predict whether a canyon remains connected to the coastline. We find that shore‐connected canyons preferentially occur along continental margins with narrow and steep shelves, such as the Mediterranean active margin and the Pacific coast of Central and South America. Moreover, our analysis supports the occurrence of such canyons offshore river basins, that are characterized by resistant bedrock and high water discharge. Such rivers deliver coarse‐grained sediment to submarine canyons, which can erode the canyon head and floor. To this end, our analysis offers new insights into the formation and maintenance of submarine canyons that are required to efficiently transport sediments, pollutants, and organic carbon from rivers to the ocean floor.
description: Key Points: Presently, 183 submarine canyons are connected to the shoreline (within 6 km) along the world’s major continents. Narrow shelves and high shelf gradients precondition the maintenance of canyon‐head connectivity to the shore. Canyon heads preferentially remain connected to the shore offshore river catchments with resistant bedrock and high water discharge.
Cinematic campfires : Australian feature film and reconciliation, 2000-2010

description: In a speech at the Sydney Film Festival in 2005, actor Tom E. Lewis likened the Australian film industry to a campfire (see Lawson, Along‚ÄövÑvp 214). His metaphor creates a picture of the cinema as a site where Aboriginal and non-Aboriginal people gather to relax, tell and listen to stories, as they would around a campfire. This image of an inclusive cinema is especially pertinent given developments in the Australian feature film industry between 2000-2010. During this time an unprecedented number of feature films that focus on settler indigenous relationships were released, drawing attention to a wide range of issues associated with co-existence. Moreover, many deploy new and sometimes challenging representational strategies to depict Aborigines, settlers, and settler-indigenous relations. The central concerns of this thesis are these films and their extra-textual contexts. Although they are a varied collection, when considered together they constitute a new movement in Australian cinema: Reconciliation Cinema. In all its guises, Reconciliation Cinema is provocative. Reconciliation is not only the key conceptual, political, personal, social, and cultural context informing these films, it is also the subject of their critiques, celebrations and contestations. It is, however, an ongoing and problematic process in a perpetual state of redefinition. In Australia, reconciliation primarily involves recognising past wrongs, addressing the inequities that have resulted from the colonisation and dispossession of Aboriginal people, and ultimately improving relationships between settler and indigenous peoples. Reconciliation Cinema contributes new ideas to this process: through nuanced, fictional representations of Aborigines, settlers and settler-indigenous relations; and through the example of collaborative filmmaking. This thesis demonstrates the centrality of Reconciliation Cinema in developing self and national understandings of reconciliation. I contend that during 2000-2010 a cinematic metanarrative of reconciliation - a conglomeration of drama, intrigue, surprise, trauma, sorrow and celebration - was firmly established in Australian cinema. This thesis comprises close readings of feature films, which reveals the ways that reconciliatory notions become manifest in cinema. In addition, it examines and analyses the broader contexts in which these films are situated. I identify three sites of intersubjectivity - on-screen, off-screen and reception (between spectator and screen) - where dated modes of cross-cultural interaction are re-negotiated, and new models of behaviour are determined.

The puzzles of dark matter searches

description: Positive results of dark matter searches in DAMA/NaI and DAMA/LIBRA experiments, being put together with negative results of other groups, can imply nontrivial particle physics solutions for cosmological dark matter. Stable particles with charge -2 bind with primordial helium in O-helium "atoms" (OHe), representing a specific Warmer than Cold nuclear-interacting form of dark matter. Slowed down in the terrestrial matter, OHe is elusive for direct methods of underground Dark matter detection like those used in CDMS experiment, but its reactions with nuclei can lead to annual variations of energy release in the interval of energy 2-6 keV in DAMA/NaI and DAMA/LIBRA experiments. Schrodinger equation for system of nucleus and OHe is solved for spherically symmetrical potential well, formed by the Yukawa tail of nuclear scalar isoscalar attraction potential, acting on He beyond the nucleus, and dipole Coulomb repulsion between the nucleus and OHe at distances from the nuclear surface, smaller than the size of OHe. The window of parameters of this potential is found, at which the sodium and/or iodine nuclei have a few keV binding energy with OHe. At nuclear parameters, reproducing DAMA results, the energy release predicted for detectors with chemical content other than NaI differ in the most cases from the one in DAMA detector. In particular, it is shown that in the case of CDMS the energy of OHe-germanium bound state is beyond the range of 2-6 keV and its formation should not lead to ionization in the energy interval of DAMA signal.

description: We use the Martian surface temperature response to Phobos transits observed next to the InSight lander in Elysium Planitia to constrain the thermal properties of the uppermost layer of regolith. Modeled transit lightcurves validated by solar panel current measurements are used to modify the boundary conditions of a 1D heat conduction model. We test several model parameter sets, varying the thickness and thermal conductivity of the top layer to explore the range of parameters that match the observed temperature response within its uncertainty both during the eclipse as well as the full diurnal cycle. The measurements indicate a thermal inertia (TI) of 103−16+22Jm−2K−1s−1/2 in the uppermost layer of 0.2–4 mm, significantly smaller than the TI of 200Jm−2K−1s−1/2 derived from the diurnal temperature curve. This could be explained by larger particles, higher density, or some or slightly higher amount of cementation in the lower layers.
description: Plain Language Summary: The Mars moon Phobos passed in front of the Sun from the perspective of the InSight lander on several occasions. The Mars surface temperatures measured by the lander became slightly colder during these transits due to the lower amount of sunlight the surface received at this time. The transits only last 20–35 s and therefore only the very top layer, about 0.3–0.8 mm, of the ground has time to cool significantly. The top layer cools and heats up faster than we expected based on the temperature changes of the day‐night cycle, which affects about 4 cm of the ground. Based on this observation we conclude that the material in the top mm of the ground is different from that below. A possible explanation would be an increase of density with depth, a larger fraction of smaller particles such as dust at the top, or a layer where particles are slightly cemented together beginning at 0.2–4 mm below the surface.
description: Key Points: The Martian surface temperature response to Phobos transits at the InSight landing site is interpreted. The thermal inertia of the uppermost layer of soil is 103−16+22Jm−2K−1s−1/2. The thermal conductivity or density of the top 0.2–4 mm is significantly less than that of the top 4 cm.

description: We construct a theory of coherent transport through a ballistic quantum dot coupled to a superconductor. We show that the leading-order quantum correction to the two-terminal conductance of these Andreev quantum dots may change sign depending on (i) the number of channels carried by the normal leads or (ii) the magnetic flux threading the dot. In contrast, spin-orbit interaction may affect the magnitude of the correction, but not always its sign. Experimental signatures of the effect include a non-monotonic magnetoconductance curve and a transition from an insulator-like to a metal-like temperature dependence of the conductance. Our results are applicable to ballistic or disordered dots.

description: Documentation of the traditional knowledge of indigenous peoples is becoming increasingly common; one reason for this is that such knowledge is becoming ever weaker and even in some cases disappearing. This is partly due to the increasing influence of Western ways of life on indigenous communities and the passing away of the older generation, taking with them a great deal of the knowledge. Indigenous peoples themselves are today often in the forefront in demanding that traditional knowledge be collected, preserved and passed on to the younger generations, and the indigenous peoples also want to be primarily responsible for such work (Burgess 1999). Traditional knowledge ranges from the limited traditions of specific families or areas to the more comprehensive traditions which the Sami people have in common, regardless of district affiliation. A Sami tradition can be very local in character and thus only apply to a small geographic area. Other Sami may not be familiar with the tradition, because they come from a locality where different customs developed (Gaup 2008). A myriad of different traditions is an expression of cultural wealth, and is also a reflection of how knowledge is adapted to the distinct ecological niches or environments found in Sápmi (Samiland). The aim of the present article is an attempt to create guidelines for how árbediehtu (Sami traditional knowledge) should be documented without exploiting the culture. The article must therefore be regarded as a contribution to an ongoing discussion.
