description: Magnetic fields without a direction of continuous symmetry have the generic feature that neighboring field lines exponentiate away from each other and become stochastic, hence the ideal constraint of preserving magnetic field line connectivity becomes exponentially sensitive to small deviations from ideal Ohm's law. The idea of breaking field line connectivity by stochasticity as a mechanism for fast reconnection is tested with numerical simulations based on reduced magnetohydrodynamics equations with a strong guide field line-tied to two perfectly conducting end plates. Starting from an ideally stable force-free equilibrium, the system is allowed to undergo resistive relaxation. Two distinct phases are found in the process of resistive relaxation. During the quasi-static phase, rapid change of field line connectivity and strong induced flow are found in regions of high field line exponentiation. However, although the field line connectivity of individual field lines can change rapidly, the overall pattern of field line mapping appears to deform gradually. From this perspective, field line exponentiation appears to cause enhanced diffusion rather than reconnection. In some cases, resistive quasi-static evolution can cause the ideally stable initial equilibrium to cross a stability threshold, leading to formation of intense current filaments and rapid change of field line mapping into a qualitatively different pattern. It is in this onset phase that the change of field line connectivity is more appropriately designated as magnetic reconnection. Our results show that rapid change of field line connectivity appears to be a necessary, but not a sufficient condition for fast reconnection.

description: Im Rahmen des leitenden Themas „Kinder auf der Flucht“ soll der Film „In This World“ als ein geeignetes Medium dienen, eine Filmanalyse unter Betrachtung medienpädagogischer Mittel vorzunehmen. Die mehrfach prämierte Semi-Dokumentation vermag die Realität unserer politischen Welt so mit Fiktion und Inszenierung zu verbinden, dass eine klare Trennung vom Zuschauer nicht mehr eindeutig auszumachen ist. Die dadurch überzeugende Darstellung der globalen Wirklichkeit bezieht sich auf eine Problematik, die trotz gesellschaftlicher Kritik oft unausgesprochen bleibt: vom Krieg und dessen Folgen, die in erster Linie die Unschuldigen oder Unbeteiligten solcher Auseinandersetzungen betreffen.

description: Der vorliegende Beitrag präsentiert die Ergebnisse einer Analyse von Kinderaufsätzen, die 10- bis 12-Jährige über ihre Lieblingsfilme verfasst haben. Der Schwerpunkt der Analyse liegt auf einer Genderperspektive: Welche Identifikationsfiguren, Themen und Interessen von Mädchen und Buben bilden sich in den Aufsätzen ab? Wie gehen die Kinder mit Geschlechterstereotypen um? Die Ergebnisse zeigen ein hohes Maß an Facettenreichtum und Individualität in den Aufsätzen – über die Geschlechtergruppen hinweg. Manche Tendenzen und Muster zeichnen sich in der einen Geschlechtergruppe stärker ab als in der anderen, augenfällige Unterschiede liegen mit wenigen Ausnahmen im untersuchten Sample aber nicht vor. Auch auf Geschlechterstereotype greifen die Kinder beim Schreiben nur selten zurück.

description: We investigate near-field infrared spectroscopy and superfluid polariton imaging experiments on conventional and unconventional superconductors. Our modeling shows that near-field spectroscopy can measure the magnitude of the superconducting energy gap in Bardeen-Cooper-Schrieffer-like superconductors with nanoscale spatial resolution. We demonstrate how the same technique can measure the c-axis plasma frequency, and thus the c-axis superfluid density, of layered unconventional superconductors with a similar spatial resolution. Our modeling also shows that near-field techniques can image superfluid surface mode interference patterns near physical and electronic boundaries. We describe how these images can be used to extract the collective mode dispersion of anisotropic superconductors with sub-diffractional spatial resolution.

description: A reasonably complete theory of the approximation of an irrational by rational fractions whose numerators and denominators lie in prescribed arithmetic progressions is developed in this paper. Results are both, on the one hand, from a metrical and a non-metrical point of view and, on the other hand, from an asymptotic and also a uniform point of view. The principal novelty is a Khintchine type theorem for uniform approximation in this context. Some applications of this theory are also discussed.

description: Nanoscale integrated photonic devices and circuits offer a path to ultra-low power computation at the few-photon level. Here we propose an optical circuit that performs a ubiquitous operation: the controlled, random-access readout of a collection of stored memory phases or, equivalently, the computation of the inner product of a vector of phases with a binary "selector" vector, where the arithmetic is done modulo 2pi and the result is encoded in the phase of a coherent field. This circuit, a collection of cascaded interferometers driven by a coherent input field, demonstrates the use of coherence as a computational resource, and of the use of recently-developed mathematical tools for modeling optical circuits with many coupled parts. The construction extends in a straightforward way to the computation of matrix-vector and matrix-matrix products, and, with the inclusion of an optical feedback loop, to the computation of a "weighted" readout of stored memory phases. We note some applications of these circuits for error correction and for computing tasks requiring fast vector inner products, e.g. statistical classification and some machine learning algorithms.

title: Effect of storage and freezing on the phenolic and antioxidant activities of raspberries

Publisher: name: University of Glasgow
Year: 2002
Subjects: subject: Food science.

description: A method was developed to analyze anthocyanins in red raspberries (Rubus idaeus L.) cv. Glen Ample. The anthocyanins were extracted from the fruit by homogenizing in acidified methanol. The methanolic extract was centrifuged and the supernatant analyzed by reverse-phase HPLC. The eluent was monitored at 371 and 520 nm before being introduced into a single quadrupole mass spectrometer through an atmospheric pressure chemical ionization probe operating in positive ion mode. This method facilitated the identification of eight anthocyanins in the raspberry matrix. Further analysis of raspberry extracts by gradient, reverse-phase HPLC with diode array detection and tandem mass spectrometry identified eleven anthocyanins, including cyanidin-3-sophoroside, cyanidin-3-(2G-glucosylrutinoside), cyanidin-3-glucoside, cyanidin-3-rutinoside, pelargonidin-3-sophoroside, pelargonidin-3-(2G-glucosylrutinoside) and pelargonidin-3-glucoside. Significant quantities of an ellagitannin, sanguiin H-6, with a Mr of 1870, were detected along with lower levels of a second ellagitannin, lambertianin C which has a Mr of 2804. Other phenolic compounds that were detected included trace levels of ellagic acid and its sugar conjugates along with one kaempferol and four quercetin-based flavonol conjugates. Fractionation by preparative HPLC revealed that sanguiin H-6 was a major contributor to the antioxidant capacity of raspbenies together with vitamin C and the anthocyanins. Vasodilation activity was restricted to fractions containing lambertianin C and sanguiin H-6. The antioxidant capacity of the fresh fruit and the levels of vitamin C and phenolics were not affected by freezing. When fruit were stored at 4
Topological Aspects of Holomorphic Mappings of Hyperquadrics from $\mathbb C^2$ to $\mathbb C^3$

Subjects: subject: Complex Variables (math.CV)

description: Based on the results in [Rei14a] we deduce some topological results concerning holomorphic mappings of Levi-nondegenerate hyperquadrics under biholomorphic equivalence. We study the class $\mathcal F$ of so-called nondegenerate and transversal holomorphic mappings sending locally the sphere in $\mathbb C^2$ to a Levi-nondegenerate hyperquadric in $\mathbb C^3$, which contains the most interesting mappings. We show that from a topological point of view there is a major difference when the target is the sphere or the hyperquadric with signature $(2,1)$. In the first case $\mathcal F$ modulo the group of automorphisms is discrete in contrast to the second case where this property fails to hold. Furthermore we study some basic properties such as freeness and properness of the action of automorphisms fixing a given point on $\mathcal F$ to obtain a structural result for a particularly interesting subset of $\mathcal F$.

description: The Coulomb repulsion between ions in a linear Paul trap give rise to anharmonic terms in the potential energy when expanded about the equilibrium positions. We examine the effect of these anharmonic terms on the accuracy of a quantum simulator made from trapped ions. To be concrete, we consider a linear chain of $\text{Yb}^{171+}$ ions stabilized close to the zigzag transition. We find that for typical experimental temperatures, frequencies change by no more than a factor of $0.01\%$ due to the anharmonic couplings. Furthermore, shifts in the effective spin-spin interactions (driven by a spin-dependent optical dipole force) also tend to be small for detunings to the blue of the transverse center-of-mass frequency. However, detuning the spin interactions near other frequencies can lead to nonnegligible anharmonic contributions to the effective spin-spin interactions. We also examine an odd behavior exhibited by the harmonic spin-spin interactions for a range of intermediate detunings, where nearest neighbor spins with a larger spatial separation on the ion chain interact more strongly than nearest neighbors with a smaller spatial separation.

description: Recent studies of animal social networks have significantly increased our understanding of animal behavior, social interactions, and many important ecological and epidemiological processes. However, most of the studies are at low temporal and spatial resolution due to the difficulty in recording accurate contact information. Domestic animals such as cattle have social behavior and serve as an excellent study system because their position can be explicitly and continuously tracked, allowing their social networks to be accurately constructed. We used radio-frequency tags to accurately track cattle position and analyze high-resolution cattle social networks. We tested the hypothesis of temporal stationarity and spatial homogeneity in these high-resolution networks and demonstrated substantial spatial-temporal heterogeneity during different daily time periods (feeding and non-feeding) and in different areas of the pen (grain bunk, water trough, hay bunk, and other general pen area). The social network structure is analyzed using global network characteristics (network density, exponential random graph model structure), subgroup clustering (modularity), triadic property (transitivity), and dyadic interactions (correlation coefficient from a quadratic assignment procedure). Cattle tend to have the strongest and most consistent contacts with others around the hay bunk during the feeding time. These results cannot be determined from data at lower spatial (aggregated at entire pen level) or temporal (aggregated at daily level) resolution. These results reveal new insights for real-time animal social network structure dynamics, providing more accurate descriptions that allow more accurate modeling of multiple (both direct and indirect) disease transmission pathways.

description: We report a combined experimental and theoretical study of the Kondo effect in a series of binuclear metal-organic complexes of the form [(Me(hfacac)_2)_2(bpym)]^0, with Me = Nickel (II), Manganese(II), Zinc (II); hfacac = hexafluoroacetylacetonate, and bpym = bipyrimidine, adsorbed on Cu(100) surface. While Kondo-features did not appear in the scanning tunneling spectroscopy spectra of non-magnetic Zn_2, a zero bias resonance was resolved in magnetic Mn_2 and Ni_2 complexes. The case of Ni_2 is particularly interesting as the experiments indicate two adsorption geometries with very different properties. For Ni_2-complexes we have employed density functional theory to further elucidate the situation. Our simulations show that one geometry with relatively large Kondo temperatures T_K ~ 10K can be attributed to distorted Ni_2 complexes, which are chemically bound to the surface via the bipyrimidine unit. The second geometry, we assign to molecular fragmentation: we suggest that the original binuclear molecule decomposes into two pieces, including Ni(hexafluoroacetylacetonate)_2, when brought into contact with the Cu-substrate. For both geometries our calculations support a picture of the (S=1)-type Kondo effect emerging due to open 3d shells of the individual Ni^{2+} ions.

Vertical velocities from proper motions of red clump giants

description: We derive the vertical velocities of disk stars in the range of Galactocentric radii of R=5-16 kpc within 2 kpc in height from the Galactic plane. This kinematic information is connected to dynamical aspects in the formation and evolution of the Milky Way, such as the passage of satellites and vertical resonance and determines whether the warp is a long-lived or a transient feature. We used the proper motions of the PPMXL survey, correcting of systematic errors with the reference of quasars. From the color-magnitude diagram K versus (J-K) we selected the standard candles corresponding to red clump giants and used the information of their proper motions to build a map of the vertical motions of our Galaxy. We derived the kinematics of the warp both analytically and through a particle simulation to fit these data. Complementarily, we also carried out the same analysis with red clump giants spectroscopically selected with APOGEE data, and we predict the improvements in accuracy that will be reached with future Gaia data. A simple model of warp with the height of the disk z_w(R,phi)=gamma (R-R_sun) sin(phi-phi_w) fits the vertical motions if d(gamma)/dt/gamma=-34+/-17 Gyr^{-1}; the contribution to d(gamma)/dt comes from the southern warp and is negligible in the north. The vertical motion in the warp apparently indicates that the main S-shaped structure of the warp is a long-lived feature, whereas the perturbation that produces an irregularity in the southern part is most likely a transient phenomenon. With the use of the Gaia end-of-mission products together with spectroscopically classified red clump giants, the precision in vertical motions can be increased by an order of magnitude at least.

description: This work is devoted to the study of a nonlocal-in-time evolutional problem for the first order differential equation in Banach space. Our primary approach, although stems from the convenient technique based on the reduction of a nonlocal problem to its classical initial value analogue, uses more advanced analysis. That is a validation of the correctness in definition of the general solution representation via the Dunford-Cauchy formula. Such approach allows us to reduce the given existence problem to the problem of locating zeros of a certain entire function. It results in the necessary and sufficient conditions for the existence of a generalized (mild) solution to the given nonlocal problem. Aside of that we also present new sufficient conditions which in the majority of cases generalize existing results.

description: In this work, we investigate thermoelectric properties of junctions consisting of two partially overlapped graphene sheets coupled to each other in the cross-plane direction. It is shown that because of the weak van-der Waals interactions between graphene layers, the phonon conductance in these junctions is strongly reduced, compared to that of single graphene layer structures, while their electrical performance is weakly affected. By exploiting this effect, we demonstrate that the thermoelectric figure of merit can reach values higher than 1 at room temperature in junctions made of gapped graphene materials, for instance, graphene nanoribbons and graphene nanomeshes. The dependence of thermoelectric properties on the junction length is also discussed. This theoretical study hence suggests an efficient way to enhance thermoelectric efficiency of graphene devices.

title: You are the Messiah and I should know - I've followed a few! Leadership and followers in the New Testament, Christian theology and Hollywood popular film
Creators: name: Lewis-Anthony, Justin
Publisher: name: University of Kent

description: "Leadership" is treated as a constant, given, virtue in our society. We expect leadership to be exercised in every sphere of human society, including the Ministry of Defence, secondary schools, the United Nations, and even the Church of England. But there appears to be no clear, concise and universally accepted definition of the term. Are we reduced to treating leadership like "obscenity" in Justice Stewart's famous definition: "we know it when we see it"? When the secular literature of leadership is examined, the only unanimity displayed is in disagreement about the sources, character and expression of leadership. This has not prevented the Church from attempting to promote "managerial-leadership" as a necessary skill for its minsters: in doing so, the Church has created something that might be called "missional-Ieadership". Neither idea represents the real source of leadership in our society, "mythological-leadership" . I examine the continuing power of myth in our culture, along with the way in which myth is transmitted by popular cinema in three categories: cinemas of "affirmation", "repudiation", and "reassertion". None disputes the basic model of the mythological leader: the man (and he is invariably a male) from outside, who comes into a community in a time of peril, defeats the evil and transforms the community by the (reluctant) exercise of violence, finally refusing any status the community wishes to confer upon him, and leaves, mortally wounded. Finally, I ask: is "leadership" no more than a useful sociological tool in the professionalization of the Church's ministry and mission? Is it, on the other hand, fatally compromised by its origins in violence and the will to power? Here the importance of Dietrich Bonhoeffer is once more presented, as a man who recognized the temptations of leadership and yet was able to assert, and model, a faithful Christian discipleship.

Bacterial production is important in aquatic carbon cycles because it represents a key component whereby dissolved and particulate carbon can be recycled back into food webs. Despite its acknowledged importance, few studies have examined bacterial production in lowland rivers. Since studies have suggested bacterial production is closely related to some carbon pools, we anticipated this to be the case in the Murray River, but that the timing and type of carbon inputs in the Murray River may lead to bacterial dynamics that differ from studies from other sites. Bacterial abundance and production were measured at three contrasting sites of the lowland Murray River, southeastern Australia, over an 18- month period. Bacterial abundance varied across the three sites on the Murray River and was correlated with chlorophyll a concentrations but not with temperature, nutrients, particulate organic carbon and dissolved organic carbon concentrations. Bacterial production also varied across the sites. Lowest production was at the site most immediately downstream of a large reservoir, with production generally ranging from 0.88 to 8.00 mu g CL-1 h(-1). Bacterial production in a reach within a large forest ranged from 4.00 to 17.38 mu CL-1 h(-1). Production at the reach furthest downstream ranged from 1.04 to 23.50 mu g C L-1 h(-1). Bacterial production in the Murray River was generally greater than in the European River Spree, reaches of the Meuse and Rhine without immediate impacts from major urban centres and the Amazon River, but was similar to the concentration measured in the Mississippi and Hudson Rivers. Bacterial production was closely correlated with chlorophyll a concentration and total phosphorus, but not with temperature, dissolved organic carbon, particulate organic carbon or inorganic nitrogen. Despite the differences in production and respiration measured at different sites across the Murray River, bacterial growth efficiency was very similar at the three sites. Bacterial populations in the Murray River appear to be influenced by reach-specific conditions rather than broad-scale drivers such as temperature, carbon and nutrient concentrations.

description: After the so-called cosmic recombination, the expanding universe entered into a period of darkness since most of the matter was in a neutral state. About a billion years later, however, the intergalactic space was once again ionized. The process, known as the cosmic reionization, required the operation of mechanisms that are not well understood. Among other ionizing sources, Population III stars, mini-quasars, and X-ray emitting microquasars have been invoked. In this article we propose that primordial cosmic rays, accelerated at the termination points of the jets of the first microquasars, may have contributed to the reionization of the intergalactic space as well. For this we quantify the ionization power of cosmic rays (electrons and protons) in the primordial intergalactic medium using extensive particle cascade simulations. We establish that, depending on the fraction of electrons to protons accelerated in the microquasar jets, cosmic rays should have contributed to the reionization of the primordial intergalactic medium as much as X-rays from microquasar accretion disks. If the primordial magnetic field was of the order of $10^{-17}$ G, as some models suggest, cosmic rays had an important role in ionizing the neutral material far beyond the birth places of the first stars.

Localization and quasilocalization of spin-$1/2$ fermion field on two-field thick braneworld

description: Localization of a spin-$1/2$ fermion on the braneworld is an important and interesting problem. It is well known that a five-dimensional free massless fermion $Ψ$ minimally coupled to gravity cannot be localized on the Randall-Sundrum braneworld. In order to trap such a fermion, the coupling between the fermion and bulk scalar fields should be introduced. In this paper, localization and quasilocalization of a bulk fermion on the thick braneworld generated by two scalar fields (a kink scalar $ϕ$ and a dilaton scalar $π$) are investigated. Two types of couplings between the fermion and two scalars are considered. One coupling is the usual Yukawa coupling $-η\barΨϕΨ$ between the fermion and kink scalar, another one is $λ\barΨΓ^{M}\partial_{M}πγ^{5}Ψ$ between the fermion and dilaton scalar. The left-chiral fermion zero mode can be localized on the brane, and both the left- and right-chiral fermion massive Kaluza-Klein modes may be localized or quasilocalized. Hence the four-dimensional massless left-chiral fermion and massive Dirac fermions, whose lifetime is infinite or finite, can be obtained on the brane.

description: Climate change is pushing to rethink the paradigm of anthropic activities. From a society strongly based on fossil fuels and their exploitation, there are many initiatives that aim at a transition towards sustainable energy sources such as the European Green Deal and the European Taxonomy on sustainable finance that aim to promote sustainability and circular economy. Thanks to technological improvements over the past decade in electric storage systems, one of the initiatives is related to the electrification of road transport. It is precisely in this transition that lithium-ion batteries have found ample space thanks to their energy density, which allows the accumulation of energy in weights and volumes that are no longer prohibitive. Looking at global electric vehicle adoption trends, it is possible to identify an exponential growth in battery demand and consequently in the consumption of raw materials such as lithium, cobalt, manganese and nickel. The extraction of these raw materials has strong environmental and social impacts and the availability of these raw materials is limited. To reduce the environmental impacts related to the extraction of raw materials and the production of lithium-ion batteries and to make supply chains more sustainable and circular, it is possible to think of recycling processes that allow the recovery of materials contained within them. The current state of the art in lithium-ion battery recycling technology involves two types of metallurgical processes: pyrometallurgy and hydrometallurgy. The former involves the use of heat to alloy the metals of interest while the latter involves the use of organic/inorganic acids for the selective extraction of those metals. This Ph.D. thesis is one of the first available works on the topic that aims to assess the techno- economic and environmental sustainability of those lithium batteries recycling processes considering different chemistries, plant scales and an Italian scenario.
