description: The nature of the electronic groundstate of Ba2IrO4 has been addressed using soft X-ray absorption and inelastic scattering techniques in the vicinity of the oxygen K edge. From the polarization and angular dependence of XAS we deduce an approximately equal superposition of xy, yz and zx Ir4+ 5d orbitals. By combining the measured orbital occupancies, with the value of the spin-orbit coupling provided by RIXS, we estimate the crystal field splitting associated with the tetragonal distortion of the IrO6 octahedra to be small, Δ=50(50) meV. We thus conclude definitively that Ba2IrO4 is a close realization of a spin-orbit Mott insulator with a jeff = 1/2 groundstate, thereby overcoming ambiguities in this assignment associated with the interpretation of X-ray resonant scattering experiments.

description: The framework of anisotropic hydrodynamics is generalized to include finite particle masses. Two schemes are introduced and their predictions compared with exact solutions of the kinetic equation in the relaxation time approximation. The first formulation uses the zeroth and first moments of the kinetic equation, whereas the second formulation uses the first and second moments. For the case of one-dimensional boost-invariant expansion, our numerical results indicate that the second formulation yields much better agreement with the exact solutions.

description: Over the last twenty years, Alternative Food Networks (AFN) have become increasingly successful at reducing the length of the chain that connects food production and consumption in an attempt to counteract the impact of the contradictions of the industrial food system and its supermarket-dominated distribution. Their grassroots actions, aimed at overcoming pre-existing socio-economic structures, are in line with social innovations, which have the objective of promoting the social participation of consumers and producers in food systems (empowerment, socio-political activism or social integration in society). In Italy, the Solidarity Purchasing Groups (SPGs), have been the subject of numerous academic studies, but the scope of these studies has, to date, been limited to the political activism of the consumer. The ability of this experience to foster the social participation of the groups’ suppliers and the effects that the exchange has on the economic life of the producers have not yet been adequately studied. This article addresses this gap by investigating the extent to which SPGs can reduce the economic marginalisation of their suppliers and evaluates if the activities they promote could increase their social participation. Based on quantitative and qualitative data, this study shows that SPGs, in contrast to other AFNs, maintain a clear separation between consumers and producers and this could mitigate the positive impact of these initiatives on their suppliers. Our analysis of the suppliers shows that SPGs can act as a safety net against economic downturns and that the social participation of the producers involved is higher at the macro, meso and individual levels, compared to producers who do not cooperate with the SPGs.

description: Using the synthesis approach of Manna and Waldinger, a formally specified and verified control circuitery for a production cell was developped. Building an appropriate formal language level, we could achieve a requirements specification to the informal description. We demonstrated that the paradigm of deductive synthesis can be applied to the development of complete verified systems, including hardware and mechanics. We defined two domain-specific logical operators that schematise frequent patterns in specification and proof and hence allow a more concise and expressive presentation. In Burghardt (1995), an english short version of this paper, without appendices, can be found.

Public policy (Law)

description: From page 382-- "I [the author] wish to argue that the analysis provided by the neoclassical model may not be an adequate guide to policy, even if certain of its predictions are correct. Instead, I [the author] direct attention to an alternative explanation of the effects of changes in the level of public debt, which leads to very different conclusions about the welfare consequences of such policies. According to this view, 'Ricardian equivalence' fails because of imperfect financial intermediation. Some economic units are liquidity constrained, which is to say that they are unable to borrow against their future income at a rate of interest as low as that at which the government borrows. Increased government borrowing can benefit such parties, insofar as they effectively receive a highly liquid asset, government debts, in exchange for giving the government an increased claim on their future income, their own claim to which represented a highly illiquid asset. A higher public debt, insofar as it implies a higher proportion of liquid assets in private sector wealth, increases the flexibility of the private sector in responding to variation in both income and spending opportunities, and so can increase economic efficiency."

Hierfür wurde die Spongiosa von 240 Wirbeln der ganzen Wirbelsäule von zehn Körperspendern mit Osteoporose hinsichtlich der BVF, der Tb.Th, der Tb.Sp., der Tb.N. und des DA untersucht. Es wurden statistisch signifikante Unterschiede zwischen den Abschnitten der HWS und denen der BWS und LWS der Wirbelsäule festgestellt. Die BVF, die Tb.Th. und die Tb.N. sind in der HWS im Vergleich zur BWS und LWS signifikant höher. Währenddessen zeigten sich die Tb.Sp. und die DA in der HWS signfikant geringer.
Self-Organized Criticality and Economic Fluctuations

description: From page 417-- "Economists have long been interested in explaining the observed instability of economic aggregates. Though several reasons for variation in the pace of production are easily given, such as exogenous variation in tastes or in production possibilities, it it hard to see why there should be large variations in those factors that are synchronized across the entire economy. Instead , it seems more likely to suppose that variations in demand or in production costs in different parts of the economy should be largely independent and hence that a law of large numbers would imply that significant variations in aggregate activity (relative to the typical size of aggregate activity) are not likely to occur.
...
Here we explore another type of explanation, which relies on an entirely different mechanism. Our proposal is that the effects of many small independent shocks to different sectors of the economy need not cancel out in the aggregate, due to the presence of significantly nonlinear, strongly localized interactions between different parts of the economy. The type of macroscopic instability that can result has been studied by condensed-matter physicists, under the name of 'self-organized criticality' (Per Bak and Kan Chen, 1991)."

While the theory of linear piezoelectric and ionic responses are well developed, the contributions of quadratic effects including electrostriction and capacitive tip-surface forces to measured signal remain poorly understood. Here we analyze the electrostrictive and capacitive contributions to the PFM and ESM signals and discuss the implications of the dielectric tip-surface gap on these interactions.

description: We study the movements in output, consumption and hours that are forecastable from a VAR and analyze how they differ from those predicted by standard real-business-cycle models. We show that actual forecastable movements in output have a variance about one hundred times larger than those predicted by the model. We also find that forecastable changes in the three series are strongly positively correlated with each other. On the other hand, for parameters whose implications are plausible in other respects, the model implies that output, consumption, and hours should not all be expected to move in the same direction
Pitfalls of Forward-Looking Monetary Policy

description: From page 100 -- "A distinctive feature of the procedures recently adopted by inflation-targeting central banks is their forward-looking character. Forecasts of the economy’s future evolution conditional upon alternative policies play a central role in the banks’ deliberations, to an extent that the procedures adopted are sometimes characterized as “forecast targeting.” This emphasis upon the future consequences of policy is unsurprising in an approach that tries to maintain as transparent as possible a relation between the banks’ decisions and the ultimate goals of monetary policy; after all, current decisions can still affect the future, but not the past.
Nonetheless, common descriptions of how inflation targeting is or should be practiced go too far, in proposing purely forward-looking procedures. I shall argue instead that an optimal framework for the conduct of monetary policy must generally be history-dependent in ways precluded by these simple proposals. This follows from a general feature of the optimal control of a forward-looking system, which is to say, one in which the private sector’s expectations about future policy are an important determinant of the effects of monetary policy."

description: The goal of this work is to make progress in the domain of near-wall velocimetry. The technique we use is based on the tracking of nanoparticles in an evanescent field, close to a wall, a technique called TIRF (Total Internal Reflection Fluorescence)-based velocimetry. At variance with the methods developed in the literature, we permanently keep track of the light emitted by each particle during the time the measurements of their positions ('altitudes') and speeds are performed. By performing the Langevin simulation, we quantified effect of biases such as Brownian motion, heterogeneities induced by the walls, statistical biases, photo bleaching, polydispersivity and limited depth of field. Using this method, we obtained slip length on hydrophilic surfaces of 1$ \pm $5 nm for sucrose solution, and 9$ \pm $10 nm for water; On hydrophobic surface, 32$ \pm $5 nm for sucrose solution, and 55$ \pm $9 nm for water. The errors (based on 95% confidence intervals) are significantly smaller than the state-of-the-art, but more importantly, the method demonstrates for the first time a capacity to measure slippage with a satisfactory accuracy, while providing a local information on the flow structure with a nanometric resolution. Our study confirms the discrepancy already pointed out in the literature between numerical and experimental slip length estimates. With the progress conveyed by the present work, TIRF based technique with continuous tracking can be considered as a quantitative method for investigating flow properties close to walls, providing both global and local information on the flow.

description: While macroeconomics is often thought of as a deeply divided field, with less of a shared core and correspondingly less cumulative progress than other areas of economics, in fact, there are fewer fundamental disagreements among macroeconomists now than in past decades. This is due to important progress in resolving seemingly intractable debates. In this paper, I review some of those debates and outline important elements of the new synthesis in macroeconomic theory. I discusses the extent to which the new developments in theory and research methods are already affecting macroeconomic analysis in policy institutions.

description: Purpose: To characterize the epithelial, stromal, and total corneal thickness profile in a
population of eyes with keratoconus.
Methods: Epithelial, stromal, and total corneal thickness profiles were measured in vivo by Artemis very high-frequency (VHF) digital ultrasound scanning (ArcScan) across the central 6- to 10-mm diameter of the cornea on 54 keratoconic eyes. Maps of the average, standard deviation, minimum, maximum, and range of epithelial, stromal, and total corneal thickness were plotted. The average location of the thinnest epithelium, stroma, and total cornea were found. The crosssectional semi-meridional stromal and total corneal thickness profiles were calculated using annular averaging. The absolute stromal and total corneal thickness progressions relative to the thinnest point were calculated using annular averaging as well as for 8 semi-meridians individually.
Results: The mean corneal vertex epithelial, stromal, and total corneal thicknesses were 45.7± 5.9 μm, 426.4 ± 38.5 μm and 472.2 ± 41.4 μm respectively. The average epithelial thickness profile showed an epithelial doughnut pattern characterized by localized central thinning surrounded by an annulus of thick epithelium. The thinnest epithelium, stroma, and total cornea were displaced on average by 0.48 ± 0.66 mm temporally and 0.32 ± 0.67 mm inferiorly, 0.31 ± 0.45 mm temporally and 0.54 ± 0.37 mm inferiorly, and 0.31 ± 0.43 mm temporally and 0.50 ±0.35 mm inferiorly, respectively, with reference to the corneal vertex. The increase in semimeridional absolute stromal and total corneal thickness progressions was greatest inferiorly and lowest temporally.
Conclusions: Three-dimensional thickness mapping of the epithelial, stromal, and total corneal thickness profiles characterized thickness changes associated with keratoconus and may help in early diagnosis of keratoconus.

description: Starting from a real standard subspace of a Hilbert space and a representation of the translation group with natural properties, we construct and analyze for each endomorphism of this pair a local, translationally covariant net of standard subspaces, on the lightray and on two-dimensional Minkowski space. These nets share many features with low-dimensional quantum field theory, described by corresponding nets of von Neumann algebras. Generalizing a result of Longo and Witten to two dimensions and massive multiplicity free representations, we characterize these endomorphisms in terms of specific analytic functions. Such a characterization then allows us to analyze the corresponding nets of standard spaces, and in particular compute their minimal localization length. The analogies and differences to the von Neumann algebraic situation are discussed.

description: We show that, by treating the gravitational interaction between two mechanical resonators as a classical measurement channel, a gravitational decoherence model results that is equivalent to a model first proposed by Diosi. The resulting decoherence model implies that the classically mediated gravitational interaction between two gravitationally coupled resonators cannot create entanglement. The gravitational decoherence rate ( and the complementary heating rate) is of the order of the gravitationally induced normal mode splitting of the two resonators.

description: Purpose: To compare corneal thickness profiles of cross-sections of cornea determined by arc-scanned immersion ultrasound and optical coherence tomography (OCT).
Methods: Corneas of 28 eyes from 14 participants were scanned in triplicate using the Artemis 2 high frequency arc-scanned ultrasound system (ArcScan Inc) and the Visante OCT system (Carl Zeiss Meditec). Corneal thickness and reproducibility were compared within 3.5 mm of central cornea in the horizontal plane.
Results: Although highly correlated, Visante central and peripheral corneal thickness values were systematically thinner than Artemis 2 values. Within the central 0.5 mm, the difference was approximately 8 μm, but the difference increased with distance from the center. Reproducibility for each instrument was comparable, measuring 4 μm centrally and increasing peripherally.
Conclusions: Visante OCT measurements of corneal thickness are thinner than Artemis 2 ultrasound values centrally with an increasing difference with peripheral position. Measurement reproducibility was comparable for the two techniques.

description: The dynamics of co- and counter-rotating coupled spherical pendulums (two lower pendulums are mounted at the end of the upper pendulum) is considered. Linear mode analysis shows the existence of three rotating modes. Starting from linear modes allow we calculate the nonlinear normal modes, which are and present them in frequency-energy plots. With the increase of energy in one mode we observe a symmetry breaking pitchfork bifurcation. In the second part of the paper we consider energy transfer between pendulums having different energies. The results for co-rotating (all pendulums rotate in the same direction) and counter-rotating motion (one of lower pendulums rotates in the opposite direction) are presented. In general, the energy fluctuations in counter-rotating pendulums are found to be higher than in the co-rotating case.

Effect of Ultrasound Radiation Force on the Choroid

Publisher: name: Columbia University
Year: 2013
Subjects: Ophthalmology

description: Purpose: While visualization of the retina and choroid has made great progress, functional imaging techniques have been lacking. Our aim was to utilize acoustic radiation force impulse (ARFI) response to probe functional properties of these tissues.
Methods: A single element 18-MHz ultrasound transducer was focused upon the retina of the rabbit eye. The procedure was performed with the eye proptosed and with the eye seated normally in the orbit. The transducer was excited to emit ARFI over a 10-ms period with a 25% duty cycle. Phase resolved pulse/echo data were acquired before, during, and following ARFI.
Results: In the proptosed eye, ARFI exposure produced tissue displacements ranging from 0 to 10 lm, and an immediate increase in choroidal echo amplitude to over 6 dB, decaying to baseline after about 1 second. In the normally seated eye, ultrasound phase shifts consistent with flow were observed in the choroid, but enhanced backscatter following ARFI rarely occurred. ARFI-induced displacements of about 10um were observed at the choroidal margins. Larger displacements occurred within the choroid and in orbital tissues.
Conclusions: We hypothesize that elevated intraocular pressure occurring during proptosis induced choroidal ischemia and that acoustic radiation force produced a transient local decompression and reperfusion. With the eye normally seated, choroidal flow was observed and little alteration in backscatter resulted from exposure. Clinical application of this technique may provide new insights into diseases characterized by altered choroidal hemodynamics, including maculopathies, diabetic retinopathy, and glaucoma.

description: Random coincidence of events (particularly from two neutrino double beta decay) could be one of the main sources of background in the search for neutrinoless double beta decay with cryogenic bolometers due to their poor time resolution. Pulse-shape discrimination by using front edge analysis, mean-time and $χ^2$ methods was applied to discriminate randomly coinciding events in ZnMoO$_4$ cryogenic scintillating bolometers. These events can be effectively rejected at the level of 99% by the analysis of the heat signals with rise-time of about 14 ms and signal-to-noise ratio of 900, and at the level of 92% by the analysis of the light signals with rise-time of about 3 ms and signal-to-noise ratio of 30, under the requirement to detect 95% of single events. These rejection efficiencies are compatible with extremely low background levels in the region of interest of neutrinoless double beta decay of $^{100}$Mo for enriched ZnMoO$_4$ detectors, of the order of $10^{-4}$ counts/(y keV kg). Pulse-shape parameters have been chosen on the basis of the performance of a real massive ZnMoO$_4$ scintillating bolometer. Importance of the signal-to-noise ratio, correct finding of the signal start and choice of an appropriate sampling frequency are discussed.

description: The vitreous body is nearly transparent both optically and ultrasonically. Conventional 10- to 12-MHz diagnostic ultrasound can detect vitreous inhomogeneities at high gain settings, but has limited resolution and sensitivity, especially outside the fixed focal zone near the retina. To improve visualization of faint intravitreal fluid/gel interfaces, the authors fabricated a spherically curved 20-MHz five-element annular array ultrasound transducer, implemented a synthetic-focusing algorithm to extend the depth-of-field, and used a pulse-encoding strategy to increase sensitivity. The authors evaluated a human subject with a recent posterior vitreous detachment and compared the annular array with conventional 10-MHz ultrasound and spectral-domain optical coherence tomography. With synthetic focusing and chirp pulse-encoding, the array allowed visualization of the formed and fluid components of the vitreous with improved sensitivity and resolution compared with the conventional B-scan. Although optical coherence tomography allowed assessment of the posterior vitreoretinal interface, the ultrasound array allowed evaluation of the entire vitreous body.

description: There have been many notable changes in the policies of the Fed and other central banks in response to the global financial crisis and its continuing aftermath, and few would disagree that the importance of these institutions for both the US and the world economy has become more evident as a result. Tonight I want to talk about only one of the notable changes in Fed policy, though it is one that I suspect will come to be seen as a change of historic significance for the institution. This is the increase in recent years in the degree to which the Fed openly discusses its policy deliberations and the bases for its decisions.

description: It is known that the Jacobian of an algebraic curve which is a 2-fold covering of a hyperelliptic curve ramified at two points contains a hyperelliptic Prym variety. Its explicit algebraic description is applied to some of the integrable Henon-Heiles systems with a non-polynomial potential. Namely, we identify the generic complex invariant manifolds of the systems as a hyperelliptic Prym subvariety of the Jacobian of the spectral curve of the corresponding Lax representation. The exact discretization of the system is described as a translation on the Prym variety.
The Preaching of Psalm 110: King, Priest, and Warrior

Subjects: royal psalm, literary, Christology, Trinity

description: Psalm 110 is the most often quoted of psalms in the New Testament and speaks of the Lord as King (vv1-3), as Priest (v.4), and as Warrior (vv. 5-7).[1]  The unique communication between the LORD and God's anointed, as 'my Lord' is remarkable. (v1.)  Could this be evidence of the Trinity as brought out by Jesus in Mark 12:35-37 and others in Hebrews 1:13 and Acts 2:34, where the Lord God promises to make a footstool to the enemies of God’s anointed priest and king?

 From a literary standpoint, this paper will evaluate the psalm’s genre, dating, and context by viewing Psalm 110 as Jewish scripture before it was adapted so strongly by Christian apologists. The paper will explore the Hebrew of some key words and each verse of the psalm as explained by commentators.

Diagnostic imaging

description: Pad-printed thick-film transducers have been shown to be an interesting alternative to lapped bulk piezoceramics, because the film is deposited with the required thickness, size, and geometry, thus avoiding any subsequent machining to achieve geometrical focusing. Their electromechanical properties are close to those of bulk ceramics with similar composition despite having a higher porosity. In this paper, padprinted high-frequency transducers based on a low-loss piezoceramic composition are designed and fabricated. High-porosity ceramic cylinders with a spherical top surface are used as the backing substrate. The transducers are characterized in view of imaging applications and their imaging capabilities are evaluated with phantoms containing spherical inclusions and in different biological tissues. In addition, the transducers are evaluated for their capability to produce high-acoustic intensities at frequencies around 20 MHz. High-intensity measurements, obtained with a calibrated hydrophone, show that transducer performance is promising for applications that would require the same device to be used for imaging and for therapy. Nevertheless, the transducer design can be improved, and simulation studies are performed to find a better compromise between low-power and high-power performance. The size, geometry, and constitutive materials of optimized configurations are proposed and their feasibility is discussed.

description: In der embryonalen Trachea existieren am Tag E14 noch keine multiziliären Zellen, sondern vorwiegend Epithelzellen mit einem Monozilium der Länge von 1 bis 2 µm. Bereits 12 Stunden später, sind schon erste multiziliäre Zellen zu beobachten. Es zeigt sich, dass neue multiziliäre Zellen vermehrt in direkter Nachbarschaft bereits vorhandener multiziliärer Zellen entstehen. Die Entwicklung des respiratorischen Epithels ist am Tag E18 weitestgehend komplettiert. Im Zeitraum von E16 bis E18 existieren in Epithelfurchen, in Abhängigkeit von deren Tiefe, vorwiegend Epithelzellen ohne Zilien.

description: We report the confirmation of the binary nature of the nearby, very low-mass system NLTT 33370 with adaptive optics imaging and present resolved near-infrared photometry and integrated light optical and near-infrared spectroscopy to characterize the system. VLT-NaCo and LBTI-LMIRCam images show significant orbital motion between 2013 February and 2013 April. Optical spectra reveal weak, gravity sensitive alkali lines and strong lithium 6708 Angstrom absorption that indicate the system is younger than field age. VLT-SINFONI near-IR spectra also show weak, gravity sensitive features and spectral morphology that is consistent with other young, very low-mass dwarfs. We combine the constraints from all age diagnostics to estimate a system age of ~30-200 Myr. The 1.2-4.7 micron spectral energy distribution of the components point toward T_eff=3200 +/- 500 K and T_eff=3100 +/- 500 K for NLTT 33370 A and B, respectively. The observed spectra, derived temperatures, and estimated age combine to constrain the component spectral types to the range M6-M8. Evolutionary models predict masses of 113 +/- 8 M_Jup and 106 +/- 7 M_Jup from the estimated luminosities of the components. KPNO-Phoenix spectra allow us to estimate the systemic radial velocity of the binary. The Galactic kinematics of NLTT 33370AB are broadly consistent with other young stars in the Solar neighborhood. However, definitive membership in a young, kinematic group cannot be assigned at this time and further follow-up observations are necessary to fully constrain the system's kinematics. The proximity, age, and late-spectral type of this binary make it very novel and an ideal target for rapid, complete orbit determination. The system is one of only a few model calibration benchmarks at young ages and very low-masses.

description: Ziel der Arbeit war es, die Interaktion zwischen T-Zellen und autologen kolorektalen Tumorzellen detailliert zu untersuchen. In Kokulturversuche beider Zellpopulationen wurde eine immunsuppressive Wirkung der Tumorzellen gegenüber den T-Zellen nachgewiesen, die auch nicht durch den Einsatz von Immuncheckpoint-Inhibitoren aufgehoben werden konnte. Eine verbesserte T-Zell-Aktivierung sowie Tumorzellerkennung wurde jedoch durch eine Peptidstimulation der T-Zellen induziert. Dabei handelte es sich neben Neoantigenen auch um tumorspezifische kryptische Peptide.
Monetary Policy Targets After the Crisis

description: In the global financial crisis and its aftermath, central banks have undertaken unprecedented actions of many kinds. This raises a natural question: has the crisis revealed that the previous consensus framework for monetary policy was inadequate, and should now be fundamentally reconsidered? It is surely true that central banks were not too well prepared for the crisis, and that new policies had to be created to a large extent on the fly. And it would obviously be desirable to try to learn from this experience, in order to be better prepared for an appropriate response next time and perhaps even to reduce the probability of there being a “next time” as well.
