description: We examine environmental auctions on working agricultural lands. We organized a discriminatory auction where farmers were asked to make bids on spreading gypsum on their fields to reduce phosphorus loads to surface waters. The parcel-specific bids were ranked based on their load reduction–compensation ratios. To assess load reductions, we built an environmental benefit index (EBI) based on three factors: P-status of the soil (phosphorus available for crops), field slope and location with respect to waterways. As the per tonne price of gypsum delivery from the factory was higher for small quantities, the auction format allowed bundling of field parcels to reduce transportation costs. We evaluate auction’s ability to target the environmental (or abatement) measures to field parcels with the highest load reduction potential and analyse the economic efficiency of the auction by comparing the pilot auction with simulated bidding behaviour and with hypothetical flat rate payment schemes. The pilot auction targeted the environmental measures effectively. It was also more efficient than a flat rate payment, even when the flat rate scheme was combined with an EBI eligibility criterion.
Der Saiga-Fund von Pahren. Ein Beitrag zur Kenntnis der paläarktischen Verbreitungsgeschichte der Gattung Saiga GRAY 1843 unter besonderer Berücksichtigung des Gebietes der DDR

description: Ausgehend von einer knappen Darstellung zur Geschichte der Erforschung fossiler Saiga-Reste auf dem Gebiet der DDR wird das bisher vorliegende Fundgut aufgeführt und durch die Beschreibung eines vermutlich letztglazialen Schädelfragmentes von Pahren bei Zeulenroda (Bezirk Gera) ergänzt. Ein Vergleich des Fossils mit entsprechenden Funden Eurasiens führt zur Unterscheidung vorläufiger Formengruppen. Offene taxonomische Probleme werden aufgezeigt. Die regionale Verbreitung fossiler Saiga-Nachweise in der DDR spiegelt den einstigen Verbreitungsraum der Gattung aus taphonomischen und forschungsgeschichtlichen Gründen nicht repräsentativ wider. Die Besiedlung der durch Funde gekennzeichneten Gebiete ist vegetationsgeschichtlich und unter Einbeziehung von Rezentbeobachtungen erklärlich. Es schließt sich ein kurzer Überblick zur bisher bekannten Verbreitungsgeschichte der Gattung Saiga im paläarktischenRaum an.

Über eine interessante Froststruktur im episodisch-solifluidal bewegten Boden während der Würmeiszeit

description: Im östlichen Teil der Stadt Bielefeld wurde ein Frostkessel festgestellt, der ca. 3 m in rote und grüne Keupermergel hineinreichte, die nur episodisch während der Würmeiszeit bewegt wurden. Seine Füllmasse bestand neben glazialem Geröll aus gelben Sanden und 4 Schichten brauner Sande mit tonigen Bestandteilen (2,5 cm mächtig), die sich warwenartig in gleichen Abständen in die gelben Sande einschalteten. Die braunen Schichten unterlagen einer Frosthebung von 5,5 cm in der Mitte, die als Auswirkung der hydratisierenden Teilchen des Mineralbodens während eines Kaltstadials in der Würmeiszeit erklärt wird. Während die gelben Sande durch Schmelzwässer bei sommerlichem Auftauen in den Spalt eingeschwemmt wurden, sind die tonigen Bestandteile vermutlich als verwitterte Keupermergel nach Austrocknen des Bodens eingeweht. Da Lößlehm über einer Steinsohle liegt, die keinerlei frostdynamischen Vorgängen mehr unterworfen war, wird angenommen, daß sich der Frostkessel in der zweiten Phase der Würmeiszeit, dem Hochglazial, gebildet hat.

description: This paper examines determinants of consumers’ willingness to pay a premium for grass-fed and organic dairy by using survey data collected from several south- eastern states. Ordered and Heckman probit regression techniques were used to identify the significance of consumer characteristics on their willingness to pay separate and comparative premiums, respectively, for the two milk product alternatives. The results indicate that while gender and household income are significant determinants of price premiums for both organic and grass-fed dairy products, only household income is positively significant in the Heckman selection estimation.
Angular momentum losses and the orbital period distribution of cataclysmic variables below the period gap: effects of circumbinary disks

description: The population synthesis of cataclysmic variables below the period is investigated. A grid of detailed binary evolutionary sequences has been calculated and included in the simulations to take account of additional angular momentum losses beyond that associated with gravitational radiation and mass loss, due to nova outbursts, from the system. As a specific example, we consider the effect of a circumbinary disk to gain insight into the ingredients necessary to reproduce the observed orbital period distribution. The resulting distributions show that the period minimum lies at about 80 minutes with the number of systems monotonically increasing with increasing orbital period to a maximum near 90 minutes. There is no evidence for an accumulation of systems at the period minimum which is a common feature of simulations in which only gravitational radiation losses are considered. The period distribution is found to be fairly flat for orbital periods ranging from about 85 to 120 minutes. The steepness of the lower edge of the period gap can be reproduced, for example, by an input of systems at periods near 2.25 hrs due to a flow of cataclysmic variable binary systems from orbital periods longer than 2.75 hrs. The good agreement with the cumulated distribution function of observed systems within the framework of our model indicates that the angular momentum loss by a circumbinary disk or a mechanism which mimics its features coupled with a weighting factor to account for selection effects in the discovery of such systems and a flow of systems from above the period gap to below the period gap are important ingredients for understanding the overall period distribution of cataclysmic variable binary systems.

description: The crystal structure of MoS$_2$ with strong covalent bonds in plane and weak Van der Waals interactions out of plane gives rise to interesting properties for applications such as solid lubrication, optoelectronics, and catalysis, which can be enhanced by transition-metal doping. However, the mechanisms for improvement and even the structure of the doped material can be unclear, which we address with theoretical calculations. Building on our previous work on Ni-doping of the bulk 2H phase, now we compare to polytypes (1H monolayer and 3R bulk), to determine favorable sites for Ni and the doping effect on structure, electronic properties, and the layer dissociation energy. The most favorable intercalation/adatom sites are tetrahedral intercalation for 3R (like 2H) and Mo-atop for 1H. The relative energies indicate a possibility of phase change from 2H to 3R with substitution of Mo or S. We find structural and electronic properties that can be used to identify the doping sites, including metallic behavior in Mo-substituted 3R and 2H, and in-gap states for Mo- and S-substituted 1H, which could have interesting optoelectronic applications. We observe a large enhancement in the interlayer interactions of Ni-doped MoS$_2$, opposite to the effect of other transition metals. For lubrication applications, this increased layer dissociation energy could be the mechanism of low wear. Our systematic study shows the effect of doping concentration and we extrapolate to the low-doping limit. This work gives insight into the previously unclear structure of Ni-doped MoS$_2$ and how it can be detected experimentally, the relation of energy and structures of doped monolayers and bulk systems, the electronic properties under doping, and the effect of doping on interlayer interactions.

description: Using a variational ansatz for the wave function of the Bose-Einstein condensate, we develop a quantum theory of vortices and quadrupole modes in a one-dimensional optical lattice. We study the coupling between the quadrupole modes and Kelvin modes, which turns out to be formally analogous to the theory of parametric processes in quantum optics. This leads to the possibility of squeezing vortices. We solve the quantum multimode problem for the Kelvin modes and quadrupole modes numerically and find properties that cannot be explained with a simple linear-response theory.

Formalizing of Category Theory in Agda

description: The generality and pervasiness of category theory in modern mathematics makes it a frequent and useful target of formalization. It is however quite challenging to formalize, for a variety of reasons. Agda currently (i.e. in 2020) does not have a standard, working formalization of category theory. We document our work on solving this dilemma. The formalization revealed a number of potential design choices, and we present, motivate and explain the ones we picked. In particular, we find that alternative definitions or alternative proofs from those found in standard textbooks can be advantageous, as well as "fit" Agda's type theory more smoothly. Some definitions regarded as equivalent in standard textbooks turn out to make different "universe level" assumptions, with some being more polymorphic than others. We also pay close attention to engineering issues so that the library integrates well with Agda's own standard library, as well as being compatible with as many of supported type theories in Agda as possible.
Mg-Ni-H films as selective coatings: tunable reflectance by layered hydrogenation

description: Unlike other switchable mirrors, Mg2NiHx films show large changes in reflection that yield very low reflectance (high absorptance) at different hydrogen contents, far before reaching the semiconducting state. The resulting reflectance patterns are of interference origin, due to a self-organized layered hydrogenation mechanism that starts at the substrate interface, and can therefore be tuned by varying the film thickness. This tunability, together with the high absorptance contrast observed between the solar and the thermal energies, strongly suggests the use of these films in smart coatings for solar applications.

description: É uma reflexão sobre o momento histórico e atual vivido pelo Estado brasileiro e as Reformas Estruturais, tendo por base os desdobramentos do Princípio da Proteção da Confiança, seus efeitos sobre o ordenamento jurídico e a indicação da chegada da "Era do Direito Conciliatório". O Princípio da Proteção da Confiança, com origem no direito administrativo, tem por objetivo garantir a proteção das expectativas legítimas, das expectativas de direitos geradas no indivíduo em decorrência de um comportamento claro e pretérito do Estado que demonstra sua inclinação a seguir e a se pautar por um determinado procedimento ou entendimento jurídico. Porém, para conferir um embasamento teórico mais substancial, a pesquisa adentra à análise do mundo jurídico e social moderno e pós-moderno. Da modernidade se extrai a construção de uma ideologia de Estado cuja estrutura era decorrência de uma mentalidade racionalista e iluminista, razão pela qual apresentava um discurso abstrato, típico do cientificismo e da metafísica. A pós-modernidade, ao contrário, atesta a quebra dos paradigmas modernos e a crise crônica de seus sistemas universalizantes. O Estado carece de legitimidade e suas políticas de eficácia. O Direito já não responde às inquietudes humanas. Entretanto, como se trata de uma época extremamente plural, se intensificaram movimentos paraestatais de efetivação dos direitos e garantias fundamentais, tanto a favor quanto contra o Estado. A violência e a miséria social em níveis alarmantes aumentaram a exigência por respostas do poder público. O Direito entra em uma era conciliatória, propondo formas alternativas para a solução dos litígios e uma mentalidade consensual para elidir conflitos. A reposta, ao que tudo indica, depende de um maior esforço do poder político do que propriamente dos órgãos judicantes, além de uma profunda alteração nas estruturas do Estado. Além disso, há uma necessidade premente pelo surgimento de um espírito conciliatório. Mais do que utopia, algo indispensável em mundo em que a justiça e a paz são desejos universais, mas que não encontra consensos, exceto, ao que parece, quanto à convicção de que toda e qualquer política de Estado e do Direito deve ter por fim a busca pela dignidade da pessoa humana.

description: Purpose. This study develops and evaluates a geese-inspired energy harmonization and leader rotation algorithm for UAV swarms, optimizing energy consumption and enhancing swarm coordination to extend mission endurance and improve operational efficiency. Design/methodology/approach. The research methodology involves a quantitative approach with controlled indoor and outdoor experiments to test the proposed algorithm, employing pre-test and post-test analysis, parallel form reliability testing, and statistical evaluations to assess battery consumption, energy harmonization effectiveness, leader rotation performance, and mission success. Findings. The study findings demonstrated that the proposed algorithm effectively balanced energy consumption across UAV swarms, improved leader-follower rotation efficiency, and extended mission endurance, with the algorithm showing significant performance improvements in both indoor and outdoor environments. Originality. This study introduces a geese-inspired energy harmonization and leader rotation algorithm that dynamically rotates leadership roles based on real-time battery levels, enhancing swarm coordination and endurance. Research limitations/implications. The research limitations are the dependence on controlled indoor and outdoor environments, which may not fully capture the complexities and challenges of real-world dynamic conditions, and the need for further validation with larger UAV swarms and extended operational scenarios. Practical implications. The practical implications of this research include the potential for enhancing the efficiency and operational range of UAV swarms in mission-critical applications such as search and rescue, environmental monitoring, and surveillance, by optimizing energy consumption and improving swarm coordination through the proposed algorithm.

description: For years, the standard procedure to measure radial velocities (RVs) of spectral observations consisted in cross-correlating the spectra with a binary mask, that is, a simple stellar template that contains information on the position and strength of stellar absorption lines. The cross-correlation function (CCF) profiles also provide several indicators of stellar activity. We present a methodology to first build weighted binary masks and, second, to compute the CCF of spectral observations with these masks from which we derive radial velocities and activity indicators. These methods are implemented in a python code that is publicly available. To build the masks, we selected a large number of sharp absorption lines based on the profile of the minima present in high signal-to-noise ratio (S/N) spectrum templates built from observations of reference stars. We computed the CCFs of observed spectra and derived RVs and the following three standard activity indicators: full-width-at-half-maximum as well as contrast and bisector inverse slope.We applied our methodology to CARMENES high-resolution spectra and obtain RV and activity indicator time series of more than 300 M dwarf stars observed for the main CARMENES survey. Compared with the standard CARMENES template matching pipeline, in general we obtain more precise RVs in the cases where the template used in the standard pipeline did not have enough S/N. We also show the behaviour of the three activity indicators for the active star YZ CMi and estimate the absolute RV of the M dwarfs analysed using the CCF RVs.

description: Die unterpleistozänen Schmelzwassersedimente im Übergangsbereich von Rhein- und Illergletscher (Baden-Württemberg, Bayern) sowie die darunter anstehenden Sedimente periglazialer Schüttungen (Ältester Periglazialschotter) werden in dieser Arbeit beschrieben. Im Vordergrund steht die geröllpetrographische und schwermineralogische Untersuchung der Sedimente aus dem Biber-, Donau- und Günz-Glazial. Die Ergebnisse bestätigen, dass die bereits von früheren Bearbeitern vorgenommene Trennung des Ältesten Periglazialschotters von den darüber lagernden Schmelzwassersedimenten aufgrund des Bestandes kristalliner Gerölle sowie auf Grund differierender Schwermineralvergesellschaftungen sicher möglich ist. Durch die hohe Beprobungsdichte ist innerhalb der glazifluviatilen Schotterniveaus eine kontinuierliche Änderung der petrographischen Zusammensetzung erkennbar. In der Geröllfraktion steigt zum Hangenden der Anteil kristalliner Gerölle und der so genannten Harten (Radiolarit, Quarzit), während sich die Karbonate verringern. Die Daten weisen darauf hin, dass es sich hierbei um eine Veränderung des Geröllspektrums und nicht um einen Verwitterungseffekt handelt. Bei den Schwermineralen sinken die Gehalte an instabilen Mineralen (Granat, Hornblende) ab, hingegen steigt der Gehalt an Staurolith zu den jüngeren Ablgaerungen stark an. Die qualitativen Ergebnisse werden in den Kontext der rekonstruierten Paläo-Talfüllungen gestellt und die flussgeschichtliche Entwicklung des Riß-Iller-Gebietes nachgezeichnet.

description: This evaluation summarizes and employs a CIPP (Context, Inputs, Processes, and Products) analysis model to evaluate the third grant year of the project. The evaluator reviewed and analyzed the context under which the grant operated, assessed the Inputs provided by the PI team and other participants, observed the Processes employed in the grant to achieve grant goals, and evaluated the Products and outcomes of the grant. This evaluation focuses on year three of a four-year grant with a fifth-year renewable clause. This assessment employed surveys, observations, interviews, participation in Zoom leadership meetings, reviews of training materials developed for the presenters, reviews of newsletters, and sampling of lesson plans developed by the participants. Seventy-eight participants attended a five-day workshop from July 29 through August 2, 2024. The sessions are convened at the Todd County Middle School in Mission, South Dakota. Significant highlights included a record participant count of 71, a substantial increase in the number of sessions, more participation and engagement of the Indigenous stakeholders to give cultural context to science lessons, the explicit introduction of sessions on Western and Indigenous content standards and building strong relationships to gain momentum in building follow-up activities. It is the overall opinion of the evaluator that the grantees made substantial progress in achieving grant objectives, produced demonstratable impacts, and continued to learn valuable lessons about how to improve and move forward in subsequent years.
Pleistozäne Dünensande in der Tschechoslowakischen Sozialistischen Republik

Year: 1963

description: Die Dünensande auf dem Gebiete der CSSR sind in verschieden großen Inseln, im Böhmischen Massiv und im Karpathenbereiche, in Seehöhen von 100—400 m verbreitet. Ihre Mächtigkeit beträgt meistens 2—10 m, stellenweise bis 30 m. Morphologisch betrachtet, bilden sie verschiedenartige Hügel und Dünen. Der Größe ihrer Körner nach bilden sie 3 Varietäten, wobei die Dünensande mit einem Korndurchmesser von 0,25—0,50 mm am meisten verbreitet sind (50—70%). In petrographischer Hinsicht überwiegt der Quarzgehalt; im Böhmischen Massiv sind sie karbonatfrei, im Karpathengebiete jedoch karbonathaltig (10—25% CaCO3). Die Entstehung der Dünensande erfolgte hauptsächlich durch Auswehung aus den Pleistozänterrassen und aus den verwitterten Gesteinen der tertiären Sedimente und aus Sandsteinen der oberen Kreideformation. Sie sind von verschiedenem pleistozänen Alter (überwiegend Riß und Würm). Sie wurden überwiegend durch Winde einer Stärke von 3—9 m transportiert.

description: Das nördliche Harzvorland liegt im Grenzbereich zwischen der ehemaligen nordischen Vereisung und dem Perigazialraum Mitteleuropas. Die ältesten pleistozänen Sedimente bilden Terrassenkiese, die vor der Elstereiszeit abgelagert wurden und einem nicht näher datierbaren Oberterrassensystem zugeordnet werden. Die Elstereiszeit ist durch Terrassenkies und glazifluviatile Sande überliefert. Die folgende Holstein-Warmzeit lässt sich nur an wenigen Stellen pedologisch nachweisen. Für den Saale-Komplex wird erstmals eine litho- und pedostratigraphische Gliederung für das Harzvorland vorgestellt. Die Fuhne-Kaltzeit und die Dömnitz-Warmzeit lassen sich anhand von Fließerden, Kaltzeitindikatoren sowie Böden belegen. Der darüber liegende Mittelterrassen-Kies der Saale-Kaltzeit stellt den wichtigsten Leithorizont im Pleistozän dar. Er lässt sich in mehrere Aufschüttungsphasen untergliedern. Darüber folgen stellenweise glazigene und glazifluviatile Sedimente. Die Entwässerung während der maximalen Ausdehnung des Eises erfolgte unter und vor dem Eis. Dieses wird durch die Anlage einer bedeutenden Talung sowie glazifluviatiler Ablagerungen belegt. Das Eis schmolz über mehrere Toteisphasen ab. In der letzten Kaltzeit herrschten im Harzvorland periglaziale Bedingungen, unter denen der Niederterrassen-Schotter in den bereits vorher existierenden Tälern abgelagert wurde.

description: We present the anisotropic optical conductivity of MgB$_{2}$ between 0.1 and 3.7 eV at room temperature obtained on single crystals of different purity by the spectroscopic ellipsometry and reflectance measurements. The bare (unscreened) plasma frequency $ω_{p}$ is almost isotropic and equal to 6.3 eV, which contrasts some earlier reports of a very small value of $ω_{p}$. The data suggests that the $σ$-bands are characterized by a stronger electron-phonon coupling $λ_ {tr}$ but smaller impurity scattering $γ_{imp}$, compared to the $π$-bands. The optical response along the boron planes is marked by an intense interband transition at 2.6 eV, due to which the reflectivity plasma edges along the a- and c-axes are shifted with respect to each other. As a result, the sample spectacularly changes color from a blueish-silver to the yellow as the polarization is rotated from the in-plane direction towards the c-axis. The optical spectra are in good agreement with the published {\it ab initio} calculations. The remaining discrepancies can be explained by the relative shift of $σ$-bands and $π$-bands by about 0.2 eV compared to the theoretical band structure, in agreement with the de Haas-van Alphen experiments. The widths of the Drude and the interband peaks are both very sensitive to the sample purity.

description: Masracetus markgrafi Gingerich, 2007
 Zeuglodon isis Stromer, 1908: 128 (in part).
 Zeuglodon cf. brachyspondylus Müller, 1849:26-28. — Stromer 1908: 136. — Kellogg 1936: 262. — Slijper 1936: 319.
 Cynthiacetus maxwelli Uhen, 2005: 160 (in part).
HOLOTYPE. — SMNS 11414, vertebral column, part of specimen ‘St. 8’ in Stromer (1908: 129). The associated skull is catalogued as SMNS 11413.
 TYPE LOCALITY AND HORIZON. — Uhen (2005) pointed out that SMNS 11414 and SMNS 11413 could come from the Gehannam Formation (Bartonian) of the Fayum Province, Egypt. However, Gingerich (2007) follows Kellogg (1936) and indicates that the holotype of M. markgrafi comes from the Birket Qarun Formation, in the vicinity of Dimeh, also in the Fayum Province. This formation is regarded as early Priabonian in age by Gingerich (1992).
 DIAGNOSIS. — Large basilosaurid lacking the vertebral elongation observed in Basilosaurus. Masracetus is slightly larger than Cynthiacetus with a lower lumbar length-to-width ratio Llum / Wlum (Gingerich 2007). DISCUSSION
 The holotype of Masracetus markgrafi was initially referred to Z. brachyspondylus (Stromer 1908) and more recently to C. maxwelli (Uhen 2005). Gingerich (2007) pointed out that Masracetus differs from other basilosaurids in the size and proportions of its lumbar vertebrae. Based on this feature, Gingerich (2007) hypothesizes that Pontogeneus brachyspondylus could be referred to Masracetus. Because a comparison of lumbar ratios in a large sampling of basilosaurid specimens (Table 2) does not clearly distinguish Cynthiacetus from Masracetus, the differences between the two genera could very well represent intra-specific variation (when compared to the variation observed in D. atrox and Z. kochii). Until study of the most complete specimen of M. markgrafi (collected in 2006: Gingerich 2007) clarifies the validity of both Masracetus and M. markgrafi, we follow Gingerich (2007) and regard M. markragi as a different species from Cynthiacetus spp.

description: In this paper, we introduce a concept of B-minimal sub-manifolds and discuss the stability of such a sub-manifold in a Riemannian manifold $(M,g)$. Assume $B(x)$ is a smooth function on $M$. By definition, we call a sub-manifold $Σ$ {\em B-minimal} in $(M,g)$ if the product sub-manifold $Σ\times S^1$ is a {\em minimal} sub-manifold in a warped product Riemannian manifold $(M\times S^1, g+e^{2B(x)}dt^2)$, so its stability is closely related to the stability of solitons of mean curvature flows as noted earlier by G. Huisken, S. Angenent, and K. Smoczyk. We can show that the "grim reaper" in the curve-shortening problem is stable in the sense of "symmetric stable" defined by K. Smoczyk. We also discuss the graphic B-minimal sub-manifold in $R^{n+k}$.

description: We propose a multivariate log-normal distribution to jointly model received power, mean delay, and root mean square (rms) delay spread of wideband radio channels, referred to as the standardized temporal moments. The model is validated using experimental data collected from five different measurement campaigns (four indoor and one outdoor scenario). We observe that the received power, mean delay and rms delay spread are correlated random variables and, therefore, should be simulated jointly. Joint models are able to capture the structure of the underlying process, unlike the independent models considered in the literature. The proposed model of the multivariate log-normal distribution is found to be a good fit for a large number of wideband data-sets.

A systematic review of the blood pressure lowering efficacy of calcium channel blockers in the treatment of primary hypertension
Creators: name: Wong, Michelle Mon Yee
Publisher: name: University of British Columbia

description: Context - Calcium channel blockers (CCBs) are widely used drugs to lower elevated blood pressure and manage angina and arrhythmias. Although the goal of antihypertensive therapy is to lower the risk of cardiovascular disease-related morbidity and mortality, efficacy is most often gauged by blood pressure reduction. Objectives — This systematic review of the blood pressure lowering efficacy of CCBs aims to determine the dose-related changes in systolic blood pressure (SBP), diastolic blood pressure (DBP), heart rate, and withdrawals due to adverse events (WDAE) with CCB treatment compared with placebo for a duration of 3-12 weeks, in patients with primary hypertension (SBP [greater than or equal to] 140 mm Hg and/or DBP [greater than or equal to] 90 mm Hg). Design — A systematic review, as per the methodology of the Cochrane Collaboration, of randomized placebo-controlled trials. Methods - Electronic databases were searched using a modified, expanded version of the search strategy used by the Cochrane Hypertension Review Group. RevMan 4.2 software was used to analyze data. Participants — 106 trials were included and reported data on 13 878 patients with a mean age of 55 years, mean baseline blood pressure of 158.2/101.6 mm Hg, mean pulse pressure of 56.7 mm Hg, and mean treatment duration of 5.7 weeks. Results — Maximal blood pressure lowering efficacy of CCBs is achieved at twice the manufacturer's recommended starting doses. This maximal reduction is 10/7 mmHg for dihydropyridines and 8/6 mmHg for non-dihydropyridines and likely represents an overestimate of the true blood pressure lowering effect due to publication bias. Combined, dihydropyridines and non-dihydropyridines lower pulse pressure by 3 mm Hg (95% CI: -4, - 2). Compared with placebo, WDAE increased in a dose-related fashion for dihydropyridines [relative risk of 1.8 (95% CI 1.2, 2.6) at 2 times the starting dose compared with 3.9 (95% CI: 2.2, 7.0) at 4 times the starting dose]. There were insufficient data to make a conclusion about the effect of non-dihydropyridines on WDAE. Conclusion — Dihydropyridines reduce blood pressure to a greater degree than nondihydropyridines. Maximal blood pressure lowering for both subclasses occurs with twice the manufacturer-recommended starting dose. Increasing the doses of dihydropyridines above recommended starting doses increases withdrawals due to adverse effects.

description: Improved optical control of molecular quantum states promises new applications including chemistry in the quantum regime, precision tests of fundamental physics, and quantum information processing. While much work has sought to prepare ground state molecules, excited states are also of interest. We demonstrate a broadband optical approach to pump trapped SiO$^+$ molecules into pure super rotor ensembles maintained for many minutes. Super rotor ensembles pumped up to rotational state $N=67$, corresponding to the peak of a 9400 K distribution, had a narrow $N$ spread comparable to that of a few-kelvin sample, and were used for spectroscopy of the previously unobserved C$^2Π$ state. Significant centrifugal distortion of super rotors pumped up to $N=230$ allowed probing electronic structure of SiO$^+$ stretched far from its equilibrium bond length.

description: Im Hinterland der Pommerschen Endmoräne in Nordostdeutschland sind zwei Kiesgruben (Kavelpaß und Wusseken) untersucht worden. Beide weisen glazifluviale Sedimente im unteren, sowie Geschiebemergel im oberen Teil der Lagerfolge auf. Sedimentologische Studien und Studien zur Eisbewegungsrichtung sind durchgeführt worden. Es ist deutlich, daß das Eis zu Beginn des Vorstoßes von Ost nach West, bzw. von Südsüdost nach Nordnordwest geflossen ist, und somit die Eisfließrichtung als abweichend von der erwarteten regionalen nordost-südwestlichen Bewegungsrichtung betrachtet werden muß. Eine Erklärung dieses Phänomens unter Zuhilfenahme des Marginaldomkonzeptes wird in dieser Arbeit vorgeschlagen.

Zur Gliederung, Bildung und Altersstellung des Kalksteinschutts am Trauf der westlichen Schwäbischen Alb

description: Nach der Größe der Gesteinsstücke und dem Gehalt an Feinbestandteilen sind die Schuttmassen am Trauf der westlichen Alb drei verschiedenen Schuttarten zuzuordnen: dem „Schutt der Scherbenhalden", dem „grobstückigen Kalkschutt" und dem „feinsplitterigen Kalkschutt". Die beiden letzteren wurden während der Würmeiszeit gebildet und transportiert, während die Scherbenhalden hauptsächlich postglazial entstanden sind. Aus dem Profilaufbau, aus der Verbreitung und dem Tiefgang der vorhandenen Taschenböden ergibt sich, daß der „feinsplitterige Kalkschutt" nur während ausgesprochener Kaltzeiten (Hochglaziale) und stellenweise (besonders am Fuße des Albtraufs) in situ aus ursprünglich grobstückigem Kalkschutt gebildet wurde.

description: We present the formation of homonuclear Cs2, K2, and heteronuclear CsK long-range Rydberg molecules in a dual-species magneto-optical trap for 39K and 133Cs by one-photon UV photoassociation. The different ground-state-density dependence of homo- and heteronuclear photoassociation rates and the detection of stable molecular ions resulting from auto-ionization provide an unambiguous assignment. We perform bound-bound millimeter-wave spectroscopy of long-range Rydberg molecules to access molecular states not accessible by one-photon photoassociation. Calculations based on the most recent theoretical model and atomic parameters do not reproduce the full set of data from homo- and heteronuclear long-range Rydberg molecules consistently. This shows that photoassociation and millimeter-wave spectroscopy of heteronuclear long-range Rydberg molecules provide a benchmark for the development of theoretical models.

description: period using the Global Corn and Soybean Policy Simulation Model. This analysis is based on a series of assumptions about general economic conditions, agricultural policies, weather conditions, and technological change. Corn-based ethanol production has influenced the United States corn industry. However, since 2010 U.S. ethanol production has remained near the 14 billion gallon level. Changes in Federal fuel mandates could significantly impact the world corn market. Under the current assumptions in the model, corn price is expected to slowly increase to $4.02 per bushel from $3.35 per bushel in 2016. Chinese soybean imports are the leading factor influencing the world soybean market. China currently imports 64% of the soybeans traded in the world market, and that is expected to increase by another 21% by 2026. Major exporters will continue to be the U.S., Brazil and Argentina. However, Brazil and Argentina are expected to increase exports while U.S. exports will remain at the current level. Soybean prices are expected to slowly increase to $9.07/bushel over the time period.
