description: Frequency dependent dynamic behavior in Piezoresponse Force Microscopy (PFM) implemented on a beam-deflection atomic force microscope (AFM) is analyzed using a combination of modeling and experimental measurements. The PFM signal comprises contributions from local electrostatic forces acting on the tip, distributed forces acting on the cantilever, and three components of the electromechanical response vector. These interactions result in the bending and torsion of the cantilever, detected as vertical and lateral PFM signals. The relative magnitudes of these contributions depend on geometric parameters of the system, the stiffness and frictional forces of tip-surface junction, and operation frequencies. The dynamic signal formation mechanism in PFM is analyzed and conditions for optimal PFM imaging are formulated. The experimental approach for probing cantilever dynamics using frequency-bias spectroscopy and deconvolution of electromechanical and electrostatic contrast is implemented.

description: Since the mid 1980s, freshwater ecosystems have experienced larger declines in biodiversity than terrestrial and marine ecosystems. Pressures on freshwater ecosystems are mainly human-induced and driven by land use changes. The objective of this paper is to evaluate how land-use adaptation to climate change affects freshwater ecosystems in France. For this purpose, we use data on land use shares (agriculture, pasture, forest and urban) and on an indicator of the ecological status of surface water, namely a fish-based index (FBI) measured for various French rivers observed between 2001 and 2013. We estimate two models: a spatial econometric land use share model and a statistical spatial panel FBI model. The land use share model describes how land use is affected by economic, physical and demographic factors, while the FBI model explains the spatial and temporal distribution of the FBI score by land use and pedo-climatic variables. Our estimation results indicate that land-use adaptation to climate change reduces freshwater biodiversity. We use our estimation results to analyze how two command-and-control policy options could help France to comply with the EU Water Framework directive and mitigate the adverse impacts of climate change on freshwater biodiversity.

description: I show that when the observables $(\vec π_{\rm E},t_{\rm E},θ_{\rm E},π_s,\vec μ_s)$ are well measured up to a discrete degeneracy in the microlensing parallax vector $\vec π_{\rm E}$, the relative likelihood of the different solutions can be written in closed form $P_i = K H_i B_i$, where $H_i$ is the number of stars (potential lenses) having the mass and kinematics of the inferred parameters of solution $i$ and $B_i$ is an additional factor that is formally derived from the Jacobian of the transformation from Galactic to microlensing parameters. The Jacobian term $B_i$ constitutes an explicit evaluation of the ``Rich Argument'', i.e., that there is an extra geometric factor disfavoring large-parallax solutions in addition to the reduced frequency of lenses given by $H_i$. Here $t_{\rm E}$ is the Einstein timescale, $θ_{\rm E}$ is the angular Einstein radius, and $(π_s,\vec μ_s)$ are the (parallax, proper motion) of the microlensed source. I also discuss how this analytic expression degrades in the presence of finite errors in the measured observables.

description: L'ensemble de ces notes ont été crée par John Baldwin lors d'une de ses premières périodes de résidence à Paris. Ces documents comprennent tous les magistri qu’il avait pu rencontrer dans ses sources. Aux XIIème et XIIIème siècles, les universités n'existant pas encore, le titre de magister s'il évoque certainement une compétence n'est pas rattaché de façon systématique au passage par les écoles. De surcroît, les magistris sont le plus souvent désignés par leur seul prénom. La lecture de ces données est donc difficile et suppose un long travail pour tenter d'identifier un individu auquel on pourrait rattacher plusieurs mentions. John Baldwin avait donc renoncé à utiliser ces données pour donner un prolongement à sa magnifique étude sur les gradués d'université et leur emploi par les Capétiens et les Plantagenêts. Néanmoins, il a conservé ces données et elles sont potentiellement très utile dans le cadre de Studium, comme le sont toutes les mentions dans les volumes des Fasti Ecclesiae Gallicanae de chanoines portant ce titre de magister sans autres précisions. L'ampleur des dépouillements rend ces données très utiles et nous devons une grande reconnaissance à John Baldwin pour avoir pris la peine de faire photocopier ses fiches et de nous les avoir transmises amicalement.
Les données ainsi que les images des fiches sont accessibles sur le site Internet à l'adresse suivante : http://studium-baldwin.lamop.fr/.
Les transcriptions des fiches ont été effectuées par des étudiants de Paris 1 Panthéon - Sorbonne mais elles n'ont pas été corrigées par la suite.

description: We show that in an asymptotically flat space where an S-Matrix can be defined, dual supertranslations leave all its matrix elements invariant and the Hilbert space of asymptotic states factorizes into distinct super-selection sectors, labeled by their dual supertranslation charges. These results suggest that dual supertranslation may be interpreted as a redundant gauge symmetry of asymptotically flat spacetimes. This would allow to recast general relativity as a theory of diffeomorphisms possessing an additional asymptotic gauge symmetry. We then use the conjectured dual supertranslation gauge symmetry to construct a gravitational equivalent of the Wu-Yang monopole solution. The metric describing the solution is defined using two overlapping patches on the celestial sphere. The solution is regular on each one of the patches separately and differentiable in the overlap region, where the two descriptions are identical by virtue of a dual supertranslation gauge transformation. Our construction provides an alternative to Misner's interpretation of the Taub-NUT metric. In particular, we find that using our approach the Taub-NUT metric can be made regular everywhere on the celestial sphere and at the same time it is devoid of closed timelike curves, provided that the bound $\frac{m}{\ell} \leq \sqrt{\frac{5}{27}}$ on the ratio of mass to NUT charge is obeyed.

description: We study extended Hubbard model on a triangular lattice near doping $x=1/3$, which may be relevant for the recently discovered superconductor Na$_x$CoO$_2 \cdot y$H$_2$O. By generalizing this model to $N$ fermionic species, we formulate a meanfield description in the limit of large $N$. In meanfield, we find two possible phases: a renormalized Fermi liquid and a $\rt3rt3$ charge density wave state. The transition between the two phases is driven by increasing the nearest neighbor repulsion and is found to be first order for doping $x=1/3$, but occurs close to the point of the local instability of the uniform liquid. We also study fluctuations about the uniform meanfield state in a systematic 1/N expansion, focusing on the residual interaction of quasiparticles and possible superconducting instabilities due to this interaction. Upon moving towards the CDW instability, the increasing charge fluctuations favor a particular $f$-wave triplet state. (This state was recently discussed by Tanakaet al, cond-mat/0311266). We also report a direct Gutzwiller wavefunction study of the spin-1/2 model.

description: Over 10 million young citrus trees have been planted each year for the past several years in Florida, largely as a result of disease and several serious freezes. These young trees require intensive management and labor inputs for survival, resulting in a plea from growers for assistance in dealing with the many problems associated with young tree care. Grower problems have been delineated by using an extension survey document. The information generated from this survey has then been used in determining research priorities. Areas currently under investigation include (among others) cold protection, weed and sprout control, irrigation, and fertilization. Technology transfer of the research is accomplished through local grower meetings and research demonstrations. The result of this program has been to successfully weld the research-extension components and provide sound production information to Florida citrus producers. ----- Se ha sembrado mas de 10 millones de arboles jovenes de dtrico en los tiltimos anos en Ia Florida, mayormente como resultado de enfermedad y varias heladas serias, Estos arboles jovenes requieren manejo y labor intensivo para sobrevivir, resultando en una petici6n de los cultivadores para asistencia en tratar con los muchos problemas asociados con el cuidado de arboles jovenes.

description: Durch Forschungen im Hochland von Angola wurden einige Beweise verschiedenartigen Ursprungs entdeckt, die auf Wirkungen kalter klimatischer Bedingungen in geologisch junger Zeit zurückgehen und wie folgt zusammengefaßt werden können: 1.Die Ausbildung einer früher oberflächenbildenden Steinsohle, wenige Dezimeter unterhalb der heutigen Topographie, scheint sehr weit verbreitet zu sein, sogar über die angegebenen Lokalitäten hinaus. 2. Warventone in der Nähe von Silva Porto entstanden gleichfalls unter ähnlichen klimatischen Einflüssen. Von besonderem Interesse ist jedoch die Diskrepanz zwischen der herkömmlichen Warvenzählung und der Auswertung von Dünnschliffen. Zusätzliche Untersuchungen an anderen Proben werden nötig sein, um das Problem weiter zu verfolgen. 3. Schließlich wurden stark verwulstete, ehemals geschichtete Materialien, Würgeböden, nahe der Oberfläche auf dem „Planalto" südlich von Nova Lisboa gefunden und makro- sowie mikroskopisch untersucht. In der vergleichenden Betrachtung der erarbeiteten verschiedenen Fakten ergibt sich aus der vorläufigen Korrelation mit der bis jetzt verfügbaren Chronologie des Quartärs das Haupt Gamblian (30500—14503 vor der Gegenwart) als Entstehungszeit.

description: This research examined the scientific exploration of human memory; it presented the stages of research in memory and the evolution of techniques to study it. The early studies were interested in evaluating memory capacity in order to construct memory span curves. It's asserted that the types of the presented information (concrete versus abstract …) influence the number of items recalled. It appears also that retention varies with interval between presentation and recall. Other works investigated the effect of sex variable on memory performance. There was a growth in memory research within the cognitive paradigm, which leads to the elaboration of models of human memory functioning.

description: We present a new method for calculating arrival distribution of UHECRs including modifications by the galactic magnetic field. We perform numerical simulations of UHE anti-protons, which are injected isotropically at the earth, in the Galaxy and record the directions of velocities at the earth and outside the Galaxy for all of the trajectories. We then select some of them so that the resultant mapping of the velocity directions outside the Galaxy of the selected trajectories corresponds to a given source location scenario, applying Liouville's theorem. We also consider energy loss processes of UHE protons in the intergalactic space. Applying this method to our source location scenario which is adopted in our recent study and can explain the AGASA observation above 4 \times 10^{19} eV, we calculate the arrival distribution of UHECRs including lower energy (E>10^19 eV) ones. We find that our source model can reproduce the large-scale isotropy and the small-scale anisotropy on UHECR arrival distribution above 10^19 eV observed by the AGASA. We also demonstrate the UHECR arrival distribution above 10^19 eV with the event number expected by future experiments in the next few years. The interesting feature of the resultant arrival distribution is the arrangement of the clustered events in the order of their energies, reflecting the directions of the galactic magnetic field. This is also pointed out by Alvarez-Muniz et al.(2002). This feature will allow us to obtain some kind of information about the composition of UHECRs and the magnetic field with increasing amount of data.

This first demonstration of electric field effect in any oxide based diluted ferromagnet is realized in a high quality epitaxial heterostructure of PbZr0.2Ti0.8O3/Co:TiO2/SrRuO3 grown on (001) LaAlO3. The observed effect, which is about 15% in strength in a given heterostructure, can be modulated over several cycles. Possible mechanisms for electric field induced modulation of insulating ferromagnetism are discussed.

description: We study the phase transitions induced by sequentially measuring a single qubit precessing under an external transverse magnetic field. Under projective quantum measurement, the probability distribution of the measurement outcomes can be mapped exactly to the thermodynamic probability distribution of a one-dimensional Ising model, whose coupling can be varied by the magnetic field from ferromagnetic to anti-ferromagnetic. For the general case of sequential quantum measurement,we develop a fast and exact algorithm to calculate the probability distribution function of the ferromagnetic order and anti-ferromagnetic order, and a phase diagram is obtained in the parameter space spanned by the measurement strength and magnetic field strength. The mapping to a long-range interacting Ising model is obtained in the limit of small measurement strength. Full counting statistical approach is applied to understand the phase diagram, and to make connections with the topological phase transition that is characterized by the braid group. This work deepens the understanding of phase transitions induced by quantum measurement, and may provide a new method to characterize and steer the quantum evolution.

description: The small, about 30% magnetoresistance at the onset of full spin polarization in the 2D electron system in a modulation-doped Si/SiGe quantum well gives evidence that it is the remote doping that determines the transport scattering time. Measurements of the mobility in this strongly-interacting electron system with remote-doping scattering allow us to arrive at a conclusion that the Hubbard form underestimates the local field corrections by about a factor of 2.

description: In this review, the fundamental structure of loop quantum gravity is presented pedagogically. Our main aim is to help non-experts to understand the motivations, basic structures, as well as general results. It may also be beneficial to practitioners to gain insights from different perspectives on the theory. We will focus on the theoretical framework itself, rather than its applications, and do our best to write it in modern and precise langauge while keeping the presentation accessible for beginners. After reviewing the classical connection dynamical formalism of general relativity, as a foundation, the construction of kinematical Ashtekar-Isham-Lewandowski representation is introduced in the content of quantum kinematics. The algebraic structure of quantum kinematics is also discussed. In the content of quantum dynamics, we mainly introduce the construction of a Hamiltonian constraint operator and the master constraint project. At last, some applications and recent advances are outlined. It should be noted that this strategy of quantizing gravity can also be extended to obtain other background independent quantum gauge theories. There is no divergence within this background independent and diffeomorphism invariant quantization programme of matter coupled to gravity.

Applied psychology in Morocco.
Creators: name: El-Mir, Mohammed
Publisher: name: figshare
Year: 2020
Subjects: Applied Psychology

description: This study examined the relationships between psychology and its applications. Although psychology in Morocco have changed in the last two decades, and realized good accumulation in basic research, but applied psychology hasn't the same dynamic, and its interaction with the social environment was limited. So, we analyzed the effect of neglecting applied psychology on the development of psychology in Morocco, because applications of psychology results are the best way to booster the psychological research. We examined also the situation of clinical psychology, and we proposed some ideas to overcome the failures of applied psychology in Morocco.
Emission and absorption lines of gamma-ray bursts affected by the relativistic motion of fireball ejecta

description: We display by numerical calculation how rest frame spectral lines appear in the observed spectrum of gamma-ray bursts due to the Doppler effect in the fireball framework. The analysis shows that: a) in the spectrum of a relativistically expanding fireball, all rest frame lines would shift to higher energy bands and would be significantly smoothed; b) rest frame weak narrow emission lines as well as narrow absorption lines and absorption line forests would be smoothed and would hardly be detectable; c) the features of rest frame broad emission lines as well as both strong and weak broad absorption lines would remain almost unchanged and therefore would be easier to detect; d) deep gaps caused by rest frame broad absorption lines would be significantly filled; e) a rest frame emission line forest would form a single broad line feature; f) the observed relative width of the rest frame very narrow line would approach $ 0.162$; g) when the Lorentz factor $Γ$ is large enough, the observed line frequency $ν_{line}$ and the rest frame line frequency $ν_{0,line} $ would be related by $ν_{line}\approx 2Γν_{0,line}$. We also investigate the effect of time dependence of the line intensity and the effect of variation of $Γ$. We find that the feature of rest frame dimming narrow emission lines would disappear when $Γ$ is very large. The form of emission lines would be sharp on both edges when $Γ$ varies with time. This phenomenon depends not only on the initial Lorentz factor but also on the observation time.

description: The National Institute for Health and Care Excellence (NICE) use economic modelling to inform judgements whenever further insight is required for decision-making. Doing so for public health guidance poses several challenges. The study’s objective was to investigate the level of heterogeneity in NICE’s public health economic models with regards to economic evaluation techniques, perspectives on outcomes and the measurement of non-health benefits.
The tables contained describe · the economic modelling techniques used in each of the 56 public health guidance topics, and;· the health and non-health criteria considered by any model that did not use the standard ‘cost utility analysis with NHS perspective’ approach.

description: A quantum computer has now solved a specialized problem believed to be intractable for supercomputers, suggesting that quantum processors may soon outperform supercomputers on scientifically important problems. But flaws in each quantum processor limit its capability by causing errors in quantum programs, and it is currently difficult to predict what programs a particular processor can successfully run. We introduce techniques that can efficiently test the capabilities of any programmable quantum computer, and we apply them to twelve processors. Our experiments show that current hardware suffers complex errors that cause structured programs to fail up to an order of magnitude earlier - as measured by program size - than disordered ones. As a result, standard error metrics inferred from random disordered program behavior do not accurately predict performance of useful programs. Our methods provide efficient, reliable, and scalable benchmarks that can be targeted to predict quantum computer performance on real-world problems.

Geschiebetransport im kanadischen und europäischen Inlandeis—ein Vergleich
Creators: name: Meyer, Klaus-Dieter
Publisher: name: Geozon Science Media
Year: 1990

description: In Nordamerika und Fennoskandia gilt Lokaltransport des Glaziärmaterials über wenige km bis 10er km als die Norm; dies nutzt die Erzprospektion. In Norddeutschland und angrenzenden Gebieten dagegen wird Ferntransport bis über 1000 km als normal angesehen; das über große Strecken homogenisierte Moränenmaterial ermöglicht Geschiebezählungen für stratigraphische Zwecke. Diese grundverschiedenen Verhältnisse galt es zu untersuchen und zu erklären. Es wurden in Kanada 3 Untersuchungsgebiete ausgewählt: Südliches Ontario; ein Profil im mittleren Ontario vom Huron-See bis südlich der Hudson-Bay und ein Profil vom W-Ende derselben durch Manitoba ins südliche Saskatchewan. In Ontario und im südlichen Umfeld der Hudson-Bay bestätigt sich der weitgehend lokale Transport, was vermutlich auf die Reliefverhältnisse zurückzuführen ist und daß über der Hudson-Bay im Gegensatz zur Ostsee zumindest zur letzten Kaltzeit kein zentraler „Eisdom" existierte. Im südlichen Sakatchewan und angrenzenden Manitoba dagegen sind die Geschiebe überwiegend Fernmaterial, mindestens 500 km weit vom Keewatin-Vereisungszentrum westlich der Hudson-Bay her transportiert, wahrscheinlich zunächst inglazial wie in Europa. In Gebieten mit überwiegendem Ferntransport ist Prospektion wenig erfolgversprechend; die Kenntnis des Geschiebetransportes ist daher Voraussetzung für die Anwendung der Geschiebestatistik. Einige mögliche Leitgeschiebe-Typen werden vorgestellt.

Die Bedeutung des Göttweiger Interstadials im Ablauf der Würm-Eiszeit
Creators: name: Gross, Hugo
Publisher: name: Geozon Science Media
Year: 1960

description: Das im Würm-Vereisungsgebiet in Oberbayern bei Hörmating entdeckte Drumlin-Profil, das E. Ebers (in diesem Jahrbuch) stratigraphisch, paläoklimatologisch und chronologisch ausgewertet hat, läßt sich genau mit dem typischen Löß-Profil im östlichen Niederösterreich, insbesondere mit seinem Fellabrunner (Göttweiger) fossilen Bodenbildungskomplex im Sinne von F. Brandtner parallelisieren. Die Zeit der Göttweiger Verlehmung ist das Hörmatinger Interstadial von ca. 47000 (oder 48000) vor heute bis zum Abschluß durch eine Torfschicht mit dem C14-Datum Gro-2593: 45300+1000 v. h. Da manche Befunde für mindestens einen Kälterückschlag sprechen, ist wohl der Name „Göttweiger Interstadial-Komplex" passender. Diese Unterbrechung des glazialen Klimas in der Würm-Eiszeit dauerte von etwa 47000 (oder 48000) bis ca. 30000 v. h. Die Vorlandvergletscherung wurde durch die Schüttung eines Vorstoßschotters eingeleitet, auf dem sehr wahrscheinlich im Paudorfer Interstadial die Innerwürm-Verwitterungsschicht (E. Kraus) entstand. Die Vorlandvergletscherung erfolgte allem Anschein nach von der Aare in der Schweiz bis zur Salzach ganz (oder fast ganz) im Hauptwürm; ihr ging eine mehrfache Schüttung älterer Würmschotter aus den Alpentälern voran. Diese älteren Würmschotter (in Hörmating mit 2-3 m mächtiger Verwitterungsrinde) können 2-3 interstadiale Schieferkohlenflöze enthalten, von denen das älteste an mehreren Orten dem letztinterglazialen Flöz aufliegt.

Multiplicative independence of modular functions

description: We provide a new, elementary proof of the multiplicative independence of pairwise distinct $\mathrm{GL}_2^+(\mathbb{Q})$-translates of the modular $j$-function, a result due originally to Pila and Tsimerman. We are thereby able to generalise this result to a wider class of modular functions. We show that this class includes a set comprising modular functions which arise naturally as Borcherds lifts of certain weakly holomorphic modular forms. For $f$ a modular function belonging to this class, we deduce, for each $n \geq 1$, the finiteness of $n$-tuples of distinct $f$-special points that are multiplicatively dependent and minimal for this property. This generalises a theorem of Pila and Tsimerman on singular moduli. We then show how these results relate to the Zilber--Pink conjecture for subvarieties of the mixed Shimura variety $Y(1)^n \times \mathbb{G}_{\mathrm{m}}^n$ and prove some special cases of this conjecture.

description: We investigate the spin-Hall effect of both electrons and holes in semiconductors using the Kubo formula in the correct zero-frequency limit taking into account the finite momentum relaxation time of carriers in real semiconductors. This approach allows to analyze the range of validity of recent theoretical findings. In particular, the spin-Hall conductivity vanishes for vanishing spin-orbit coupling if the correct zero-frequency limit is performed.

Leptogenesis from Split Fermions

Year: 2004
Subjects: subject: High Energy Physics - Phenomenology (hep-ph)
subject: FOS: Physical sciences

description: We present a new type of leptogenesis mechanism based on a two-scalar split-fermions framework. At high temperatures the bulk scalar vacuum expectation values (VEVs) vanish and lepton number is strongly violated. Below some temperature, $T_c$, the scalars develop extra dimension dependent VEVs. This transition is assumed to proceed via a first order phase transition. In the broken phase the fermions are localized and lepton number violation is negligible. The lepton-bulk scalar Yukawa couplings contain sizable CP phases which induce lepton production near the interface between the two phases. We provide a qualitative estimation of the resultant baryon asymmetry which agrees with current observation. The neutrino flavor parameters are accounted for by the above model with an additional approximate U(1) symmetry.
