description: Über die Tatsache, dass eine
      Qualitätssicherung notwendig ist, herrschte so gut wie kein
      Zweifel mehr. Wie genau dies jedoch von Statten gehen sollte,
      war zum Zeitpunkt der Befragung nicht einheitlich geklärt. Je
      nach zu messender Spule wurde ein anderes zeitliches Vorgehen
      bei der Durchführung der Qualitätssicherung gewählt.
      Qualitätssicherung wurde zu einem hohen Prozentsatz an den
      Servicetechniker abgegeben, welcher routinemäßig in
      bestimmten zeitlichen Abständen zur technischen Wartung die
      Klinik oder das Institut aufsuchte. Das Signal‐Rausch
      Verhältnis war der am meisten genutzte Parameter um einen
      schnellen Überblick über die Qualität der Messdaten zu
      erlangen. Verschieden weitere Parameter wurden zusätzlich mit
      einbezogen, abhängig von den jeweiligen Kliniken oder
      Instituten. Hier zeigte sich u.a. eine große
      Variationsbreite. Die Einschätzung der Qualität der eigenen
      Daten war akzeptabel, wurde jedoch besser eingeschätzt, wenn
      eine Qualitätssicherung in recht häufigen zeitlichen
      Abständen erfolgte.
description: The aim of this work should be ‐
      on the model of ( Koller, Eatough et al 2006.) to give an
      overview of the MRI machines and to present the extent to
      which quality assurance is carried out. Here, a focus was set
      on the exact implementation of quality assurance, the
      acceptance of quality assurance and self‐assessment of the
      quality of the own data. Methodology: The study consisted of
      a cross‐sectional survey. 192 questionnaires have been sent
      to clinics and institutes. The number of clinics participants
      in the survey and institutes amounted to n= 71. Results:
      There is no doubt about the fact that quality assurance is
      necessary. How exactly quality assurance should go, was not
      uniformly understood at the time of the survey. Depending on
      the coil for measuring, a different temporal approach in the
      implementation of quality assurance was elected. Quality
      assurance was traded to a high percentage of the service
      technician, who routinely visited the clinic or institution
      in certain time intervals. The signal‐to‐noise ratio could
      obtain as the most utilized parameter for a quick overview of
      the quality of the measurement data. Various other parameters
      were also included, depending on the clinics or institutions.
      The assessment of the quality of the own data was acceptable,
      but was better assessed when a quality assurance was carried
      out.

description: We introduce a new kind of percolation on finite graphs called jigsaw percolation. This model attempts to capture networks of people who innovate by merging ideas and who solve problems by piecing together solutions. Each person in a social network has a unique piece of a jigsaw puzzle. Acquainted people with compatible puzzle pieces merge their puzzle pieces. More generally, groups of people with merged puzzle pieces merge if the groups know one another and have a pair of compatible puzzle pieces. The social network solves the puzzle if it eventually merges all the puzzle pieces. For an Erdős-Rényi social network with $n$ vertices and edge probability $p_n$, we define the critical value $p_c(n)$ for a connected puzzle graph to be the $p_n$ for which the chance of solving the puzzle equals $1/2$. We prove that for the $n$-cycle (ring) puzzle, $p_c(n)=Θ(1/\log n)$, and for an arbitrary connected puzzle graph with bounded maximum degree, $p_c(n)=O(1/\log n)$ and $ω(1/n^b)$ for any $b>0$. Surprisingly, with probability tending to 1 as the network size increases to infinity, social networks with a power-law degree distribution cannot solve any bounded-degree puzzle. This model suggests a mechanism for recent empirical claims that innovation increases with social density, and it might begin to show what social networks stifle creativity and what networks collectively innovate.

description: The recent financial and real
      economic crises have made it clear that macroeconomists need
      to better account for the influence of financial markets.
      This paper explores the consequences of treating the
      interaction between different financial markets, monetary
      policy, and the real economy seriously by developing a fully
      dynamic theoretical model in continuous time. Starting from a
      standard New Keynesian framework, we reformulate and extend
      the model by means of stochastic differential equations so as
      to analyse spillover effects and steady-state properties. We
      solve the nonlinear model using stochastic differential
      equations rather than third-order perturbation. Applying
      Bayesian estimation methods, we estimate the model for the US
      economy and analyse the financial markets influence on
      business cycles and monetary policy.
description: Die aktuelle Finanz- und
      Schuldenkrise hat die Fiskal- und Geldpolitik sowie
      Finanzmärkte in den Fokus akademischer Forschung und der
      Gesellschaft insgesamt gebracht. Insbesondere hat die Krise
      auch die internationalen Zusammenhänge und Transmissionen von
      Schocks aufgezeigt: ökonomische Schocks streuen auf andere
      Märkte und greifen auf andere Länder über, mit teilweise
      schwerwiegenden Effekten. Das bessere Verständnis dieser
      Zusammenhänge kann daher einen signifikanten Einfluss auf
      internationale Politik haben und diese maßgeblich verbessern.
      Politiker können so koordiniert Fiskal- und Geldpolitik
      betreiben, wobei Fiskalpolitiker zur Stabilisierung der
      Märkte zwischen Ausgabenpolitik und Sparpolitik entscheiden
      müssen während Geldpolitiker mit dem Problem der
      Nullzinsgrenze umgehen müssen. Insbesondere der Einfluss von
      Finanzmärkten und wie die Politik, vornehmlich die
      Geldpolitik, auf diese reagieren soll und wenn ja in welchem
      Ausmaß, wird seit der Finanzkrise 2007/2008 von
      Wirtschaftsforschern weltweit analysiert und

description: The present paper shows that if $q \in \mathbb P$ or $q = 0$, where $\mathbb P$ is the set of prime numbers, then there exist characteristic $q$ fields $E _{q,k}\colon \ k \in \mathbb N$, of Brauer dimension Brd$(E _{q,k}) = k$ and infinite absolute Brauer $p$-dimensions abrd$_{p}(E _{q,k})$, for all $p \in \mathbb P$ not dividing $q ^{2} - q$. This ensures that Brd$_{p}(F _{q,k}) = \infty $, $p \dagger q ^{2} - q$, for every finitely-generated transcendental extension $F _{q,k}/E _{q,k}$. We also prove that each sequence $a _{p}, b _{p}$, $p \in \mathbb P$, satisfying the conditions $a _{2} = b _{2}$ and $0 \le b _{p} \le a _{p} \le \infty $, equals the sequence abrd$_{p}(E), {\rm Brd}_{p}(E)$, $p \in \mathbb P$, for a field $E$ of characteristic zero.

description: In this paper, we study the problem of moving $n$ sensors on a line to form a barrier coverage of a specified segment of the line such that the maximum moving distance of the sensors is minimized. Previously, it was an open question whether this problem on sensors with arbitrary sensing ranges is solvable in polynomial time. We settle this open question positively by giving an $O(n^2 \log n)$ time algorithm. For the special case when all sensors have the same-size sensing range, the previously best solution takes $O(n^2)$ time. We present an $O(n \log n)$ time algorithm for this case; further, if all sensors are initially located on the coverage segment, our algorithm takes $O(n)$ time. Also, we extend our techniques to the cycle version of the problem where the barrier coverage is for a simple cycle and the sensors are allowed to move only along the cycle. For sensors with the same-size sensing range, we solve the cycle version in $O(n)$ time, improving the previously best $O(n^2)$ time solution.
description: This version corrected an error in the proof of Lemma 2 in the previous version and the version published in DCG 2013. Lemma 2 is for proving the correctness of an algorithm (see the footnote of Page 9 for why the previous proof is incorrect). Everything else of the paper does not change. All algorithms in the paper are exactly the same as before and their time complexities do not change either

description: Consider a sequence of minimal varieties M_i in a Riemannian manifold N such that the boundary measures are uniformly bounded on compact sets. Let Z be the set of points at which the areas of the M_i blow up. We prove that Z behaves in some ways like a minimal variety without boundary: in particular, it satisfies the same maximum and barrier principles that a smooth minimal submanifold satisfies. For suitable open subsets W of N, this allows one to show that if the areas of the M_i are uniformly bounded on compact subsets of W, then the areas are in fact uniformly bounded on all compact subsets of N. Similar results are proved for varieties with bounded mean curvature. Applications include a version of Allard's boundary regularity theorem in which no mass bounds are assumed.

description: Calorie restriction (CR) has been shown to extend the mean and maximum lifespan in both preclinical and clinical settings. We have previously demonstrated that CR attenuates lipopolysaccharide (LPS)-induced fever and sickness behavior. CR also leads to reductions in pro-inflammatory and increases in anti-inflammatory profiles. LPS is a bacterial mimetic; however, few studies have explored this phenomenon utilizing a viral mimetic, such as polyinosinic:polycytidylic acid (poly I:C). Dose-dependently, poly I:C induced an increase in core body temperature (Tb), with the largest dose (5000 µg/kg) resulting in a 1.62 °C ( ± 0.23 °C) Tb increase at 7 h post-injection in ad libitum mice and was associated with reduced home-cage locomotor activity. We then investigated the effect of 50% CR for 28 days to attenuate fever and sickness behavior induced by a poly I:C (5000 µg/kg) viral immune challenge. CR resulted in the partial attenuation of fever and sickness behavior measures post-poly I:C. The freely fed, control mice demonstrated a 2.02 °C ( ± 0.22 °C) increase in Tb at 7 h post-injection compared to the CR poly I:C group which demonstrated an increase in Tb of 0.94 °C ( ± 0.27 °C). Locomotor patterns post-injection were different, CR mice displayed a reduction in activity during the light phase, and the control group displayed a reduction during the dark phase. CR moderately attenuated the neuroinflammatory response with a reduction in microglial density in the ventromedial nucleus of the hypothalamus. The fever and sickness behavior attenuation seen after CR may be driven by similar anti-inflammatory processes as after LPS; however, further investigation is required.

description: We present a modification of Matrix Product State time evolution to simulate the propagation of signal fronts on infinite one-dimensional systems. We restrict the calculation to a window moving along with a signal, which by the Lieb-Robinson bound is contained within a light cone. Signal fronts can be studied unperturbed and with high precision for much longer times than on finite systems. Entanglement inside the window is naturally small, greatly lowering computational effort. We investigate the time evolution of the transverse field Ising (TFI) model and of the S=1/2 XXZ antiferromagnet in their symmetry broken phases after several different local quantum quenches. In both models, we observe distinct magnetization plateaus at the signal front for very large times, resembling those previously observed for the particle density of tight binding (TB) fermions. We show that the normalized difference to the magnetization of the ground state exhibits similar scaling behaviour as the density of TB fermions. In the XXZ model there is an additional internal structure of the signal front due to pairing, and wider plateaus with tight binding scaling exponents for the normalized excess magnetization. We also observe parameter dependent interaction effects between individual plateaus, resulting in a slight spatial compression of the plateau widths. In the TFI model, we additionally find that for an initial Jordan-Wigner domain wall state, the complete time evolution of the normalized excess longitudinal magnetization agrees exactly with the particle density of TB fermions.

description: The coordination chemistry of the homo- and heterodipnictogen tetrahedrane complexes [{CpMo(CO)2}2(μ,η2:2-EE′)] (E, E′ = P, As, Sb) (A–F) toward Tl[BArF24] ([BArF24]− = [B(3,5-C6H3(CF3)2)4]−) was studied. Controlled by the used tetrahedranes A–F, and thus depending on the respective pnictogen atoms, the monomers [Tl(η2-A)][BArF24] ([A]Tl) and [Tl(η2-B)][BArF24] ([B]Tl), the double substituted [Tl(η1-C)2][BArF24] ([C]2Tl) or the even higher aggregated compounds [Tl2(η2-D)3(μ,η2:1-D)(μ,η1:1-D)][BArF24]2 ([D]5Tl2), [Tl2(η2-E)2(μ,η2:1-E)3] [BArF24]2 ([E]5Tl2) and [Tl2(η2-F)3(μ,η2:1-F)3][BArF24]2 ([F]6Tl2) were obtained. Utilization of [BArF24]− promises additional stabilization of TlI via η6-coordination of two of its aryl rings as found in compounds [A]Tl, [B]Tl and [C]2Tl. Within the series of reactivity of A–F, the heavier congeners D, E and F tend to form larger aggregates in which σ(E–E′) bond contributions to the coordination behavior were observed. Interatomic distances suggest the presence of Tl···Tl interactions in [E]5Tl2 and [F]6Tl2. The features of the respective coordination compounds were studied in the solid-state as well as in solution. For the latter at least a partial dissociation of the assemblies in solution was indicated. The isolated solid-state aggregates are the first examples of heterodipnictogen units as ligands in self-assembled TlI-based coordination compounds.

description: For graphs $G_1, G_2, G_3$, the three-color Ramsey number $R(G_1,$ $G_2, G_3)$ is the smallest integer $n$ such that if we arbitrarily color the edges of the complete graph of order $n$ with 3 colors, then it contains a monochromatic copy of $G_i$ in color $i$, for some $1 \leq i \leq 3$. First, we prove that the conjectured equality $R_3(C_{2n},C_{2n},C_{2n})=4n$, if true, implies that $R_3(P_{2n+1},P_{2n+1},P_{2n+1})=4n+1$ for all $n \ge 3$. We also obtain two new exact values $R(P_8,P_8,P_8)=14$ and $R(P_9,P_9,P_9)=17$, furthermore we do so without help of computer algorithms. Our results agree with a formula $R(P_n,P_n,P_n)=2n-2+(n\bmod 2)$ which was proved for sufficiently large $n$ by Gyárfás, Ruszinkó, Sárközy, and Szemerédi in 2007. This provides more evidence for the conjecture that the latter holds for all $n \ge 1$.

description: Equivariant tree models are statistical models used in the reconstruction of phylogenetic trees from genetic data. Here equivariant refers to a symmetry group imposed on the root distribution and on the transition matrices in the model. We prove that if that symmetry group is Abelian, then the Zariski closures of these models are defined by polynomial equations of bounded degree, independent of the tree. Moreover, we show that there exists a polynomial-time membership test for that Zariski closure. This generalises earlier results on tensors of bounded rank, which correspond to the case where the group is trivial, and implies a qualitative variant of a quantitative conjecture by Sturmfels and Sullivant in the case where the group and the alphabet coincide. Our proofs exploit the symmetries of an infinite-dimensional projective limit of Abelian star models.

We benchmark the hydrodynamics capabilities of GenASiS against many standard test problems; the results illustrate the basic competence of our implementation, demonstrate the strengths and limitations of the HLLC relative to the HLL Riemann solver in a number of interesting cases, and provide preliminary indications of the code's ability to scale and to function with cell-by-cell fixed-mesh refinement.

description: Abstract
In many arid and semi-arid regions, large amounts of water annually flood the desert during extreme rainfall events without harvesting. Intervention to harvest water through subsurface dam is important to improve water supply during dry season in Chad. This research aims to test effectiveness of the subsurface dam to guarantee and store water during wet season to be used during dry season. A subsurface dam has been built in the Wadi that crosses the village of Korlongo.Korlongo located in the Dangaleat East canton, Abtouyour department in Guera province, Republic of Chad. The subsurface  dam was built of a trench crossing the wadi. A plastic sheet is placed in the trench and glued to the bottom to stop the subsurfaces lateral flow of water and thus delay the possible drying up of a well placed in upstream. Water levels were monitored using piezometers. The results confirmed that the subsurface dam provides significant volume of water upstream. The water levels at upstream, drops less quickly during the dry season compared with downstream. Despite the daily withdrawal of water from the well, the dam makes water available throughout the year at upstream. A t-test indicates significant difference (p = .002) between the water levels upstream and downstream.  The findings show the effectiveness of the subsurface dam in providing sustainable water in semi-arid and arid region.

description: The use of the von Neumann entropy in formulating the laws of thermodynamics has recently been challenged. It is associated with the average work whereas the work guaranteed to be extracted in any single run of an experiment is the more interesting quantity in general. We show that an expression that quantifies majorisation determines the optimal guaranteed work. We argue it should therefore be the central quantity of statistical mechanics, rather than the von Neumann entropy. In the limit of many identical and independent subsystems (asymptotic i.i.d) the von Neumann entropy expressions are recovered but in the non-equilbrium regime the optimal guaranteed work can be radically different to the optimal average. Moreover our measure of majorisation governs which evolutions can be realized via thermal interactions, whereas the nondecrease of the von Neumann entropy is not sufficiently restrictive. Our results are inspired by single-shot information theory.

description: We investigate the Boltzmann equation, depending on the Knudsen number, in the Navier-Stokes perturbative setting on the torus. Using hypocoercivity, we derive a new proof of existence and exponential decay for solutions close to a global equilibrium, with explicit regularity bounds and rates of convergence. These results are uniform in the Knudsen number and thus allow us to obtain a strong derivation of the incompressible Navier-Stokes equations as the Knudsen number tends to $0$. Moreover, our method is also used to deal with other kinetic models. Finally, we show that the study of the hydrodynamical limit is rather different on the torus than the one already proved in the whole space as it requires averaging in time, unless the initial layer conditions are satisfied.

description: In a microcanonical ensemble (constant $NVE$, hard reflecting walls) and in a molecular dynamics ensemble (constant $NVE\mathbf{PG}$, periodic boundary conditions) with a number $N$ of smooth elastic hard spheres in a $d$-dimensional volume $V$ having a total energy $E$, a total momentum $\mathbf{P}$, and an overall center of mass position $\mathbf{G}$, the individual velocity components, velocity moduli, and energies have transformed beta distributions with different arguments and shape parameters depending on $d$, $N$, $E$, the boundary conditions, and possible symmetries in the initial conditions. This can be shown marginalizing the joint distribution of individual energies, which is a symmetric Dirichlet distribution. In the thermodynamic limit the beta distributions converge to gamma distributions with different arguments and shape or scale parameters, corresponding respectively to the Gaussian, i.e., Maxwell-Boltzmann, Maxwell, and Boltzmann or Boltzmann-Gibbs distribution. These analytical results agree with molecular dynamics and Monte Carlo simulations with different numbers of hard disks or spheres and hard reflecting walls or periodic boundary conditions. The agreement is perfect with our Monte Carlo algorithm, which acts only on velocities independently of positions with the collision versor sampled uniformly on a unit half sphere in $d$ dimensions, while slight deviations appear with our molecular dynamics simulations for the smallest values of $N$.

description: Animals must invest some portion of their metabolism to activities related to physiological maintenance and the remainder to processes related to the production of new biomass for growth and reproduction. Animal metabolism is fuelled by food, and the quality and quantity of food, along with the effort invested to obtain it, are fundamental to supporting populations. Biofilms are a primary basal food resource within riverine food webs, and it is thought that their nutritional value for animals decreases with age due to dynamic changes in community composition. We sought to test assumptions of spatiotemporal changes to biofilm nutritional value by assessing variations in biofilm mass and fatty acid composition in three rivers for 73 days. We also used a multi-prong eDNA approach to characterize changes to biofilm fungal (ITS1–4), bacterial (16S), and algal (23S) community compositions. We anticipated biofilm food value to decrease with biofilm age due to shifts in composition from high-quality green algae and diatoms to low-quality cyanobacteria and filamentous algae. Our results partially support this contention; biofilm food value, assessed as a combination of fatty acid mass per unit area (in grams per square meter) and concentration of fatty acids (in milligrams per gram), was dynamic and peaked between 24 and 43 days following submersion. After 43 days, biofilm food value decreased. However, despite significant temporal changes in biofilm community composition and a decrease in overall lipid concentration, the proportions of different fatty acid classes among total lipids did not vary. Instead, the observed increase in the abundance of cyanobacteria and filamentous algae compared with diatoms and green algae, along with higher quantities of lipid-poor extracellular polymeric substances (EPS), likely contributed to the reduction in overall lipid concentration relative to the biofilm dry mass. Here we present a novel approach to balance consumer energetic costs with food quality within aquatic food webs. Our results have important implications for river management and provide valuable information for the use of environmental water to support lotic ecosystems.

description: We reconsider the recent observation by the D0 experiment of a sizable like-sign dimuon charge asymmetry, highlighting that it could be affected by CP-violating New Physics contributions not only in Bd- and Bs-meson mixings, but also in semileptonic decays of b and c quarks producing muons. The D0, measurement could be reconciled with the Standard Model expectations for neutral-meson mixings, provided that the CP asymmetry in semileptonic b (c) decays reaches 0.3 % (1%). Such effects, which lie within the available (rather loose) experimental bounds, would be clear indications of New Physics and should be investigated experimentally.
description: Corrected discussion of the SM contributions to the direct semileptonic CP asymmetries in B decays. Main results and conclusions unchanged

Energy of test objects on black hole spacetimes: A brief review

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

description: In this paper, we review the issue of defining energy for test particles on a background stationary spacetime. We revisit the different notions of energy as defined by different observers. As is well known, the existence of a time-like isometry allows for the notion of total conserved energy to be well defined. We use this well known quantity to show that a gravitational potential energy can be consistently defined. As examples, we study the case of the exterior regions of an asymptotically flat black hole and of the $Λ>0$ Schwarzschild de Sitter case, where an asymptotic region is not available. We then consider the situation in which the test particle is absorbed by the black hole, and analyze the energetics in detail. In particular, we show that the notion of horizon energy as defined by the isolated horizons formalism provides a satisfactory notion of energy compatible with the particle's total conserved energy. With these choices, there is a global conservation of energy. Finally, we comment on a recent proposal to define energy of the black hole as seen by a nearby observer at rest, for which this feature is lost.

Spectral Analysis and Long-Time Behaviour of a Fokker-Planck Equation with a Non-Local Perturbation

description: In this article we consider a Fokker-Planck equation with a non-local, mass preserving perturbation. We show that the perturbed Fokker-Planck operator generates a $C_0$-semigroup on an exponentially weighted $L^2$-space. Surprisingly, the spectrum of the Fokker-Planck operator is not affected by the perturbation. In particular there still exists a unique (normalized) stationary solution of the perturbed equation. And we have convergence towards the stationary state with exponential rate -1, the same rate as for the unperturbed Fokker-Planck equation. Moreover, for any $k\in\mathbb N$ there exists an invariant subspace with finite codimension in which the exponential decay rate equals $-k$. As a byproduct of our analysis we characterize the spectrum of the Fokker-Planck operator in $L^2$-spaces with exponential weights.

description: While working in the life-space of children and youth it is hard to imagine an interaction that does not contain some level of caring or love that guides interventions and interactions while being governed by professional boundaries. Caring and love in practice requires a level of reflection that acts as a check to ensure these boundaries are adhered to. This article is a reflexive moment in an experienced Child and Youth Care Practitioner's career when a youth who she had cared for was involved in a motor vehicle accident and died.
Educating for allyship: Innovative faculty development to support students and signal allyship

description: • Background: Undergraduate medical learners from historically marginalized groups face significant barriers, which we saw at our institution when a student’s research revealed the uncertainty of Black students at our institution regarding which faculty members to trust. In response, the diversity committee and faculty development department saw the need for a visible group of faculty to act as “safe” confidants for our historically marginalized learners.
 • Summary of Work: Using Kern’s curriculum development model we created a faculty allyship curriculum (FAC) involving: 9 hours of Diversity, Equity, and Inclusion (DEI) faculty development, a virtual DEI journal club, and written reflections at two points in the program. We also gathered written session evaluations after each virtual workshop and a program questionnaire to all participants after 16 months
 • Summary of Results: Ninety Allyship faculty development workshops were offered over 16 months, 40 of which were offered virtually for geographically dispersed faculty. To date, 790 individuals have attended at least one workshop, and 20 individuals have completed FAC, earning visible lapel pins.
 Virtual session evaluations had a 39% (301/773) response rate, with 99% rating workshops excellent or good. There was a 10% (75/790) response rate for the program questionnaire, with 91% reporting that the Allyship program impacted their teaching practice somewhat or to a great extent. The majority reported that the program helped them feel at least moderately confident in teaching learners underrepresented in medicine (77%), mentor learners different than they are (84%), and teach allyship topics (71%).
 Open-ended responses revealed changes in faculty awareness, attitude, and use of language; use of allyship materials in teaching, curricular development, or scholarly activity; use of new knowledge in mentorship, supervision, and leadership; and increased engagement in advocacy and microaggression responses.
 • Discussion and Conclusion: We believe that FAC has created a community of educators learning about DEI together and committed to supporting learners from historically marginalized groups. Some keys to our success were relying on a pre-existing faculty development program, beginning with volunteers, striving for psychological safety for all levels of DEI learners, and modeling imperfection and upstanding behaviors.
