description: Evaporation experiments are frequently used to determine soil hydraulic properties. We simulated laboratory evaporation experiments with a coupled water, vapor, and heat flow model which includes the surface energy balance. The simulations are performed with different parametrizations of soil hydraulic properties with a focus on soil hydraulic conductivity in medium to dry soil. In previous studies, conductivity in this moisture range has been shown to be influenced not only by water flow in completely filled capillaries (“capillary flow”) but also by film and corner flow (“film flow”). Our forward simulations highlight the strong influence of an increased conductivity caused by film flow on evaporation rate, cumulative water loss, soil temperature, and soil water pressure head during evaporation. Film flow extends the duration of stage‐1 evaporation and increases the evaporation rate during stage‐2 even if all other physical material properties are the same. The simulated data were used in inverse simulations with the Richards equation to test whether soil hydraulic properties can be identified without bias. This is a priori questionable because the Richards equation is an isothermal flow model and simplifies the true physics considerably, by ignoring thermal liquid and thermal vapor fluxes, as well as temperature effects on the hydraulic properties. Our results show that the identification of the water retention and hydraulic conductivity curves is bias‐free for media with and without film flow. We conclude that the Richards equation can be safely used to identify hydraulic properties from evaporation experiments by inverse modeling.
description: Key Points: Coupled modeling of water, vapor, and heat flow shows that film‐flow extends stage‐1 and changes the evaporation dynamics during stage‐2. Soil hydraulic properties identified by inverse modeling with the Richards equation are unbiased despite strong temperature dynamics. Inadequate models for soil hydraulic properties lead to a grossly wrong prediction of the pressure head in medium to dry soils.

description: In this paper a new framework has been applied to the design of controllers which encompasses nonlinearity, hysteresis and arbitrary density functions of forward models and inverse controllers. Using mixture density networks, the probabilistic models of both the forward and inverse dynamics are estimated such that they are dependent on the state and the control input. The optimal control strategy is then derived which minimizes uncertainty of the closed loop system. In the absence of reliable plant models, the proposed control algorithm incorporates uncertainties in model parameters, observations, and latent processes. The local stability of the closed loop system has been established. The efficacy of the control algorithm is demonstrated on two nonlinear stochastic control examples with additive and multiplicative noise.

description: We study nucleon-nucleon scattering on the lattice at next-to-leading order in chiral effective field theory. We determine phase shifts and mixing angles from the properties of two-nucleon standing waves induced by a hard spherical wall in the center-of-mass frame. At fixed lattice spacing we test model independence of the low-energy effective theory by computing next-to-leading-order corrections for two different leading-order lattice actions. The first leading-order action includes instantaneous one-pion exchange and same-site contact interactions. The second leading-order action includes instantaneous one-pion exchange and Gaussian-smeared interactions. We find that in each case the results at next-to-leading order are accurate up to corrections expected at higher order.

description: In southern Iberia, the surroundings of the Strait of Gibraltar are known as a crossroad for population movements, cultural exchanges, and trade from Late Prehistory to modern times. However, questions remain about the impact of this historical development on the environment. The settlement of La Silla del Papa, an important hillfort in southern Andalusia (Cádiz), was occupied during the entire Iron Age, replaced by the coastal town Baelo Claudia during Roman times, and re‐occupied during Early Medieval times. As such, La Silla del Papa and its territory represent an ideal location for long‐term studies on human‐environment interactions. Within the framework of the interdisciplinary project “Archeostraits,” geoarchaeological investigations in the surroundings of La Silla del Papa aimed at constraining ecological conditions and human‐environment interactions during the mid‐ and late Holocene and during major human occupation phases. Our results document an early mid‐Holocene marine embayment in the lower floodplain of the Río del Cachón, rapidly turning into a coastal lagoon and later into freshwater‐dominated wetlands. After approximately 2100 BP (c. 150 BC), fluvial and alluvial deposition i600ing a high anthropogenic impact on the local landscape during Roman or post‐Roman times. Palynological results reveal fluctuating agricultural and pastoral activities and distinct periods of landscape opening during the Neolithic and Iron Age.

description: The medium modifications of the masses of the charmonium states (J/$ψ$, $ψ$(3686) and $ψ$(3770)) in asymmetric nuclear matter in the presence of strong magnetic fields are studied using an effective chiral model. The mass modifications arise due to medium modifications of the scalar dilaton field, which simulates the gluon condensates of QCD within the effective hadronic model. The effects due to the magnetic field as well as isospin asymmetry are observed to be appreciable at high densities for the charmonium states, which can have consequences, e,g, in the production of the open charm mesons and the charmonium states, in the asymmetric heavy ion collisions at the compressed baryonic matter (CBM) experiments at the future facility at GSI. The presence of magnetic field leads to Landau quantization of the energy levels of the proton in the asymmetric nuclear matter. The effects of the anomalous magnetic moments of the proton and neutron on the masses of the charmonium states are studied and are observed to lead to larger masses of the charmonium states, as compared to when these effects are not taken into account.

description: During the combustion of biomass, which represents in the heating sector the most important renewable energy source with 84 %, different pollutants such as NOx and PM are emitted.[3] In order to reduce NOx catalysts are used in the SCR process of flue gas cleaning. The industrial used V2O5-based catalyst is in the criticism of having a high operating temperature between 300 °C to 400 °C and because the active vanadium species has a toxicity.[4] By changing the active metal for this catalyst from vanadium to other transition metals like manganese, the environmental aspect of the catalyst can be improved since an active species such as MnOx is not as toxic as V2O5 and has an operating temperature between 150 °C and 300 °C. The DeNOx-DePM project also tries to improve the environmental aspect in the synthesis by using microwave technology instead of conventional heating. The last environmental aspect of the project lies in its concept. Other than in industrial used flue gas cleaning, the catalyst should be added as an additive directly into the flue gas, which is than removed together with the particulate matter on a fabric filter to build a catalytic active filter cake, which can be cleaned by jet pules.[5] This helps the process, since the powerplant does not need to shut down for the renewing of the catalyst.
description: Green chemistry describes the environmentally friendly chemical synthesis in order to minimize environmental pollution by substituting towards nontoxic chemicals and optimizing the energy use in the synthesis.[1,2] As such the DeNOx-DePM project which aims for the combined reduction of NOx and particulate matter (PM) approaches the selective catalytic reduction (SCR) of NOx as well as the catalytic preparation with an emphasis on the principals of green chemistry.

description: Abstract A few months before his death, A. v. Humboldt attended the celebration in honor of the 127th birthday of George Washington at the US legation in Berlin. A letter to the American Envoy, Joseph A. Wright (1810–1867), underlines Humboldt’s admiration for the first president of the United States. At the same time Humboldt asked the diplomat to mail a letter to the German-American Bernard Moses (1832–1897) in Clinton, Louisiana, who had named his son Alexander Humboldt Moses (grave on the Hebrew Rest Cemetery #2 in New Orleans, burial plot A, 12, 5). It appears to be possible that the Moses family still owns Humboldt’s letter. Zusammenfassung Wenige Monate vor seinem Tod besuchte A. v. Humboldt die Feier zu Ehren des 127.

description: Globular complexes were introduced by E. Goubault and the author in arXiv:math/0107060 to model higher dimensional automata. Globular complexes are topological spaces equipped with a globular decomposition which is the directed analogue of the cellular decomposition of a CW-complex. We prove that there exists a combinatorial model category such that the cellular objects are exactly the globular complexes and such that the homotopy category is equivalent to the homotopy category of flows introduced in arXiv:math/0308054. The underlying category of this model category is a variant of M. Grandis' notion of d-space over a topological space colimit generated by simplices. This result enables us to understand the relationship between the framework of flows and other works in directed algebraic topology using d-spaces. It also enables us to prove that the underlying homotopy type functor of flows constructed in arXiv:math/0308063 can be interpreted up to equivalences of categories as the total left derived functor of a left Quillen adjoint.

description: Einstein`s equivalence principle states the complete physical equivalence of a gravitational field and corresponding inertial field in an accelerated reference frame. However, to what extent the equivalence principle remains valid in non-relativistic quantum mechanics is a controversial issue. To avoid violation of the equivalence principle, Bargmann`s superselection rule forbids a coherent superposition of states with different masses. Here we suggest a quantum simulation of non-relativistic Schrödinger particle dynamics in non-inertial reference frames, which is based on propagation of polarization-entangled photon pairs in curved and birefringent optical waveguides and Hong-Ou-Mandel quantum interference measurement. The photonic simulator can emulate superposition of mass states, which would lead to violation of the EP.

description: Parametric resonance or preheating is a plausible mechanism for bringing about the transition between the inflationary phase and a hot, radiation dominated universe. This epoch results in the rapid production of heavy particles far from thermal equilibrium and could source a significant stochastic background of gravitational radiation. Here, we present a numerical algorithm for computing the contemporary power spectrum of gravity waves generated in this post-inflationary phase transition for a large class of scalar-field driven inflationary models. We explicitly calculate this spectrum for both quartic and quadratic models of chaotic inflation, and low-scale hybrid models. In particular, we consider hybrid models with an ``inverted'' potential. These models have a very short and intense period of resonance which is qualitatively different from previous examples studied in this context, but we find that they lead to a similar spectrum of gravitational radiation.

description: We report the effect of pressure on the electrical transport properties of the four-layer-type bismuth chalcogenide semiconductors LaOPbBiS$_{3}$ and La$_{2}$O$_{2}$Bi$_{3}$AgS$_{6}$ and present the discovery of a pressure-induced superconductivity. In both compounds, the semiconductorlike behavior concomitant with an anomaly in the more insulating state is gradually suppressed with increasing pressure while the superconductivity develops. The obtained phase diagrams, in sharp contrast with the interplay between the conventional charge density waves and superconductivity, suggest that the enhancement of the superconductivity is due to the disorder near the localization threshold. These results indicate that pressure tuning of the local disorder in four-layer-type bismuth chalcogenides provides an attractive opportunity to study the interplay between disorder and superconductivity.

description: Site‐specific soil fertility management requires a fundamental understanding of factors that modulate soil fertility variability in the local context. To verify this assumption, this study hypothesized that soil fertility variability across two regions in Central and Western Ethiopia is determined by inter‐related effects of agro‐ecological zones and farmers’ resource endowment (‘wealthy’ versus ‘poor’ farmers). Mid‐infrared spectroscopy coupled to partial least squares regression (midDRIFTS‐PLSR) and wet‐laboratory analyses were used to assess the soil fertility (soil pH, total soil carbon [TC] and nitrogen [TN], plant‐available phosphorous [Pav] and potassium [Kav]) across four agro‐ecological zones: ‘High‐Dega’ (HD), ‘Dega’ (D), ‘Weina‐Dega’ (WD) and ‘Kola’ (K). MidDRIFTS peak area analysis of spectral frequencies (2,930 [aliphatic C‐H], 1,620 [aromatic C = C], 1,159 [C‐O poly‐alcoholic and ether groups] cm‐1) was applied to characterize soil organic carbon (SOC) quality and to calculate the SOC stability index (1,620:2,930). Higher TC in HD, as well as higher TN and Kav contents in K were found in fields of wealthy compared with poor farmers. Resource endowment dependent soil fertility management options revealed SOC of higher quality in wealthy compared with poor farms in D. Agro‐ecological zones distinctions contributed to these soil fertility differences. Farmers distinguished visually fertile and less fertile fields based on soil colour. Higher pH in K and WD as well as Pav in K and HD were found in fertile (brown/black) than less fertile (red) soils. To conclude, tailor‐made soil fertility management in the local context must consider agro‐ecological zones and resource endowment interactions along with farmers’ indigenous knowledge.

description: Zusammenfassung Der deutsche Mineraloge und Bergingenieur August Schmidt (1802 – 1832) nahm im Jahr 1829 an einer Etappe der „Russisch-Sibirischen Reise“ Alexander von Humboldts teil. Bisher war über Schmidt so wenig bekannt, dass die Forschungsliteratur nicht einmal seinen richtigen Vornamen verwendete. Dieser Artikel präsentiert neue Erkenntnisse über seine Biografi e und verfolgt den Weg, der ihn zu einer Anstellung als Bergwerksdirektor in den Ural und zur Teilnahme an Humboldts Reise führte. Humboldt erwartete ebenso wie die anderen an der Reise teilnehmenden Mineralogen, im Ural Diamanten zu fi nden. Diese Erwartungshaltung war bereits in den Jahren vor der Reise durch einen internationalen Wissensaustausch zu den geologischen Ähnlichkeiten der Kontinente entstanden, an dem Alexander von Humboldt maßgeblich beteiligt war. Abstract August Schmidt (1802 – 1832), a German mineralogist and mining engineer, took part in a stage of Alexander von Humboldt’s Russian-Siberian Journey in 1829. Until now, so little was known about Schmidt that the few scholars who mentioned him did not even use his real fi rst name. This article presents new fi ndings about his biography and traces the path that led him to employment as a mine director in the Urals and to his participation in Humboldt’s voyage. Humboldt, as well as the other participating mineralogists, expected to find diamonds in the Urals. These expectations arose years before the trip through an international exchange of knowledge about the geological similarity of the continents, in which Alexander von Humboldt played a key role.

Резюме Август Шмидт (1802 – 1832), немецкий минералог и горный инженер, принимал участие в одном из этапов российско-сибирского путешествия Александра фон Гумбольдта в 1829 году. До сих пор о Шмидте было известно так мало, что те немногие ученые, которые упоминали его, даже не использовали его настоящее имя. В этой статье представлены новые сведения о его биографии и прослеживается путь, который привел его к назначению на должность Управляющего рудником на Урале и к участию в путешествии Гумбольдта. Гумбольдт, как и другие минералоги-участники, рассчитывали найти алмазы на Урале. Эти ожидания возникли за годы до поездки в результате международного обмена знаниями о геологическом сходстве континентов, в котором Александр фон Гумбольдт сыграл ключевую роль.

description: Global greening trends have been widely reported based on long‐term remote sensing data of terrestrial ecosystems. Typically, a hypothesis test is performed for each grid cell; this leads to multiple hypothesis testing and false positive trend detection. We reanalyze global greening and account for this issue with a novel statistical method that allows robust inference on greening regions. Based on leaf area index (LAI) data, our methods reduce the detected greening from 35.2% to 15.3% of the terrestrial land surface; this reduction is most notable in nonwoody vegetation. Our results confirm several greening regions (China, India, Europe, Sahel, North America, Brazil, and Siberia), that are also supported by independent data products. We also report evidence for an increasing seasonal amplitude in LAI north of 35°N. Considering the widespread use of spatially replicated trend tests in global change research, we recommend adopting the proposed multiple testing procedure to control false positive outcomes.
description: Plain Language Summary: Using satellite data, recent studies have detected an increase in vegetation greenness around the globe. These studies attribute this vegetation increase to different factors, such as warming or land use change. However, we argue that the commonly used analysis method is detecting too many regions with trends. In this work, we reanalyze vegetation data using the leaf area index, which measures the area occupied by leaves in any given area. With our refined methods, we too detect greening regions around the world, however these regions are smaller and less abundant. Our research introduces a step in the statistical analysis that increases the reliability of the detected vegetation greening. This can help establish more consensus on what the main contributing factors are for the observed vegetation increase.
description: Key Points: Many studies have consistently reported on global greening trends, but repeatedly without rigorous significance testing. Although global greening has been overestimated, significant greening can still be rigorously detected. We observe an increase in the seasonal amplitude of leaf area index around the glob.

Here the same lattice action is used to simulate the ground state of up to 12 neutrons in a periodic cube using Monte Carlo. We explore the density range from 2% to 8% of normal nuclear density and analyze the ground state energy as an expansion about the unitarity limit with corrections due to finite scattering length, effective range, and P-wave interactions.

description: We use deep Herschel observations of the complete 2Jy sample of powerful radio AGNs in the local universe (0.05 < z < 0.7) to probe their cool interstellar medium (ISM) contents and star-forming properties, comparing them against other samples of nearby luminous AGNs and quiescent galaxies. This allows us to investigate triggering and feedback mechanisms. We find that the dust masses of the strong-line radio galaxies (SLRGs) in our sample are similar to those of radio-quiet quasars, and that their median dust mass (Mdust = 2 x 10^7 Msun) is enhanced by a factor ~200 compared to that of non-AGN ellipticals, but lower by a factor ~16 relative to that of local ultra-luminous infrared galaxies (UILRGs). Along with compelling evidence for merger signatures in optical images, the SLRGs in our sample also show relatively high star-formation efficiencies, despite the fact that many of them fall below the main sequence for star forming galaxies. Together, these results suggest that most of our SLRGs have been re-triggered by late-time mergers that are relatively minor in terms of their gas contents. In comparison with the SLRGs, the radio AGNs with weak optical emission lines (WLRGs) and edge-darkened radio jets (FRIs) have both lower cool ISM masses and star-formation rates (by a factor of >30), consistent with being fuelled by a different mechanism (e.g. the direct accretion of hot gas).

description: In this paper we propose and discuss coherent terahertz sources based on charge density wave (plasmon) amplification in two dimensional graphene. The coupling of the plasmons to interband electron-hole transitions in population inverted graphene layers can lead to plasmon amplification through stimulated emission. Plasmon gain values in graphene can be very large due to the small group velocity of the plasmons and the strong confinement of the plasmon field in the vicinity of the graphene layer. We present a transmission line model for plasmon propagation in graphene that includes plasmon dissipation and plasmon interband gain due to stimulated emission. Using this model, we discuss design for terahertz plasmon oscillators and derive the threshold condition for oscillation taking into account internal losses and also losses due to external coupling. The large gain values available at terahertz frequencies in graphene can lead to integrated oscillators that have dimensions in the 1-10 micron range.

description: Ultrastructural fluctuations at nanoscale are fundamental to assess properties and functionalities of advanced out-of-equilibrium materials. We have taken myelin as a model of supramolecular assembly in out-of-equilibrium living matter. Myelin sheath is a simple stable multi-lamellar structure of high relevance and impact in biomedicine. Although it is known that myelin has a quasi-crystalline ultrastructure there is no information on its fluctuations at nanoscale in different states due to limitations of the available standard techniques. To overcome these limitations, we have used Scanning micro X-ray Diffraction, which is a non-invasive probe of both reciprocal and real space to visualize statistical fluctuations of myelin order of the sciatic nerve of Xenopus Laevis. The results show that the ultrastructure period of the myelin is stabilized by large anti-correlated fluctuations at nanoscale, between hydrophobic and hydrophilic layers. The ratio between the total thickness of hydrophilic and hydrophobic layers defines the conformational parameter, which describes the different states of myelin. Our key result is that myelin in its out-of-equilibrium functional state fluctuates point-to-point between different conformations showing a correlated disorder described by a Levy distribution. As the system approaches the thermodynamic equilibrium in an aged state the disorder loses its correlation degree and the structural fluctuation distribution changes to Gaussian. In a denatured state at low pH, it changes to a completely disordered stage. Our results clarify also the degradation mechanism in biological systems by associating these states with variation of the ultrastructural dynamic fluctuations at nanoscale.

description: Zusammenfassung Aus Archivfunden und historischen Zeitungsberichten rekonstruiert der Artikel die Lebensspuren von August Schmidt (1802–1832) während seiner Tätigkeit im Ural als Mineraloge und Bergwerksverwalter. Ausführlich werden die von Schmidt angewendeten naturwissenschaftlichen Analysemethoden beschrieben, mit denen ihm der eindeutige Nachweis der ersten gefundenen Ural-Diamanten gelang. Schmidt überbrachte Alexander von Humboldt (1769–1859) einen der Diamanten als Geschenk seines Vorgesetzten, Adolphe Graf von Polier (1795–1830), und erhielt die Gelegenheit, Humboldt seine eigenen Ideen zur technischen Modernisierung und zur Energieeinsparung vorzustellen. Der frühe Tod von August Schmidt, der im Ural Fjodor Fjodorowitsch Schmidt genannt wurde, verhinderte weitgehend die Verwirklichung dieser Ideen und führte durch die Vornamensunterschiede zu gerichtlichen Auseinandersetzungen um seinen Nachlass. Abstract August Schmidt (1802–1832) during his time in the Urals as a mineralogist and mining administrator. The scientific analysis methods used by Schmidt with which he was able to clearly identify the first Ural diamonds found are described in detail. Schmidt presented Alexander von Humboldt (1769–1859) one of the diamonds as a gift from his superior, Adolphe Comte de Polier (1795–1830), and was given the opportunity to present Humboldt his own ideas for technical modernization and energy economy. The early death of August Schmidt, who was called Fyodor Fyodorovich Schmidt in the Urals, largely prevented the realization of these ideas and led to legal disputes over his estate due to the difference in first names. Резюме В статье на основе архивных материалов и исторических газетных сообщений реконструируется жизнь Августа Шмидта (1802–1832 гг.) во время его работы на Урале в качестве минералога и Управляющего рудником. Подробно описаны методы научного анализа, использованные Шмидтом, с помощью которых он смог однозначно идентифицировать первые найденные уральские алмазы. Шмидт передал Александру фон Гумбольдту (1769–1859) один из алмазов в качестве подарка от своего начальника, графа Адольфа Польера (1795–1830), и получил возможность представить Гумбольдту свои собственные идеи по технической модернизации и энергосбережению. Ранняя смерть Августа Шмидта, которого на Урале называли Фёдором Фёдоровичем Шмидтом, во многом помешала реализации этих идей и привела к судебным спорам по делам его наследствa из-за разного написания имени.

description: Ecotoxicological effect assessment of particulate materials and sparingly soluble substances is an emerging field. Current standard toxicity tests of aquatic organisms are based on soluble substances which are added to the aqueous phase. Although soluble substances distribute homogeneously, particles can form aggregates, resulting in inhomogeneous distribution and unpredictable exposure. Therefore, test scenarios need to be adapted to overcome these uncertainties. We present a dietary particle exposure tool for the toxicity testing of sparingly soluble substances or particles in combination with a standardizable food source for gammarids based on decomposition and consumption tablets (DECOTABs). Four food supplements in the DEOCOTAB formulation were compared to test their influence on the energy reserves of gammarids. Although feeding rate was constant for most supplements, mortality and energy reserves revealed clear differences. Tabs supplemented with algae‐based phyll or animal protein–based trout food best met all of the requirements. Fluorescent plastic microparticles (10–65 µm) were homogenously distributed and stable in the DECOTABs. Constant feeding was observed, and the number of ingested microparticles by Gammarus roeseli was quantified in relation to the consumed food. The developed method provides a realistic and methodologically reliable uptake from the oral pathway and allows the quantification of inner exposition via feeding rate, providing a promising tool for standardized dietary exposure scenarios with particles.

description: Zusammenfassung Ausgehend von einem Brief Alexander von Humboldts an die Schriftstellerin Therese von Bacheracht (1804 – 1852) wird die Geschichte der Herausgabe der Briefe seines Bruders Wilhelm an Charlotte Diede im Jahr 1847, nach dem Tod beider Korrespondenten, nachgezeichnet. Besonders wird dabei auf die bisher unveröffentlichten „Tagesblätter“ Karl August Varnhagens von Ense zurückgegriffen, aus denen hervorgeht, dass Alexander von Humboldt seine anfangs ablehnende Haltung aufgibt, Varnhagen mit der Prüfung und Korrektur des Manuskripts betraut, und dass Therese von Bacheracht durch Hartnäckigkeit und Charme ihr Ziel erreicht, die nicht unbeträchtlichen Einnahmen aus der Veröffentlichung zugesprochen zu bekommen. Abstract Using a letter written by Alexander von Humboldt to the writer Therese von Bacheracht (1804 – 1852), this paper tells the story of how Humboldt’s brother Wilhelm’s letters to Charlotte Diede were published in 1847, after the death of both correspondents. The emphasis is placed on the hitherto unpublished daily journals (Tagesblätter) of Karl August Varnhagen von Ense. Not only do they show how gradually Alexander von Humboldt abandons his former adverse attitude towards the project, but also that he asks Varnhagen to proofread the manuscript and that, by perseverance and her charming attitude, Therese von Bacheracht succeeds in obtaining considerable profi ts from the publication of the letters. Résumé Sur la base d’une lettre d’Alexander von Humboldt à l’écrivain Therese von Bacheracht (1804 – 1852), on retrace l’histoire de la publication des lettres de son frère Wilhelm à Charlotte Diede en 1847, après la mort des deux correspondants. En particulier, on utilise les « Tagesblätter » inédits de Karl August Varnhagen von Ense, dont il ressort qu’Alexander von Humboldt renonce à son attitude initialement négative, confi e à Varnhagen la révision et la correction du manuscrit, et que Therese von Bacheracht avec persévérance et charme atteint leur objectif de se voir attribuer les revenus non négligeables de la publication.
