Creators: name: Mozzoni, David
Publisher: name: Deutsches GeoForschungsZentrum GFZ
Year: 2008

description: In this study two aspects of the geomagnetic field have been investigated. The first partfocuses on perturbations of the external field, as seen by the CHAMP satellite and predicted by the Thermosphere-Ionosphere Electrodynamic General Circulation Model, for the purpose of helping to separate out ionospheric sources from the ambient geomagnetic field using a physics based approach. Part two looks at variations of the internal field through an examination of the South Atlantic Anomaly.

description: The majority of experimental realizations of single-electron sources rely on the periodic manipulation of the tunnel junctions through their gate voltages, and thus require a high level of control over the system. To circumvent the necessity of external driving, we utilize the self-oscillatory behavior of the electron shuttle. By means of waiting time distributions, which had not been applied to this autonomous system before, we extensively assess the performance of the shuttle as a single-electron source. We unveil a smooth transition between three regimes, whereas previous studies at the same mean field level of description only predict a sharp bifurcation based on the time-averaged electron current. Over the parameter range of already existing experimental realizations the electron shuttle can perform as a single-electron source, albeit with moderate precision. We propose an alternative design of the position-dependent tunneling rates, which significantly decreases the relative error of charge transmission, and thus paves the way for the realization of autonomous single-electron sources.

title: Ground-based GPS altimetry with the L1 OpenGPS receiver using carrier phase-delay observations of reflected GPS signals
Creators: name: Helm, Achim
Publisher: name: Deutsches GeoForschungsZentrum GFZ
Year: 2008

description: This study presents methods and field experiments for ground-based GPS altimetry. Although Coarse/Acquisition Code (C/A-code) based methods are introduced, the main part of this work addresses the use of carrier phase-delay observations of the reflected GPS signal and focuses on specular reflection. [...] This study approves the feasibility of ground-based GPS altimetry with the OpenGPS receiver and with only one low-gain and wide field-of-view RHCP antenna using L1 carrier phase-delay observations of reflected GPS signals. The work shows the potential of GPS reflectometry for remote water level monitoring from a safe position in cases where in-situ measurements are not possible, are dangerous or sensors may get destroyed by the highly dynamic sea or glacier environment.

title: The upper atmospheric fountain effect in the polar cusp region
Creators: name: Marker [Rentz], Stefanie
Publisher: name: Deutsches GeoForschungsZentrum GFZ
Year: 2009

description: [...] According to the results of this thesis the following mechanism is suggested tocause the cusp-related density anomaly: The energy input by the solar wind, ascharacterised by the merging electric field, provides the power for Joule heating ofpreferably neutral molecules. Soft particle precipitation in the cusp simultaneouslyenhances the altitude of maximal Pedersen conductivity, thus lifting up the heatedlayer in the cusp. The cusp-related density anomaly is then caused by local compositionchanges in the upper atmosphere due to the differential expansion of heavierparticles. The density enhancement is more intensive during phases of high solaractivity, i.e. a larger background density favours the formation of large anomalies.The atmospheric fountain in the cusp region affects the upper atmosphere globally.The harmonic exitation of the fountain in 2005 caused a global density variation ofthe thermosphere.

description: We explore the phenomena of quadrature squeezing of photons in the Two-Photon Dicke Model under the mean-field approximation in the thermodynamic limit. The strength of photon squeezing is maximized in the region where the coupling strength is of the same order of magnitude as one of the fundamental frequency of the system. This particular region is termed as the unbounded region. The squeezing of the photonic quadratures can be observed only in the superradiant phase where the squeezing is well beyond the standard quantum limit both near the quantum critical point as well as the unbounded region. However, prolonged squeezing is only obtained in the latter case. Furthermore, we explore the critical behavior of photon squeezing near the unbounded region.

title: Investigations on rainfall variability during the late Quaternary based on geochemical analyses of lake sediments from tropical and subtropical southern Africa
Creators: name: Kristen, Iris
Publisher: name: Deutsches GeoForschungsZentrum GFZ
Year: 2009

description: This thesis presents investigations on sediments from two African lakes which have been recording changes in their surrounding environmental and climate conditions since more than 200,000 years. Focus of this work is the time of the last Glacial and the Holocene (the last ~100,000 years before present [in the following 100 kyr BP]). One important precondition for this kind of research is a good understanding of the present ecosystems in and around the lakes and of the sediment formation under modern climate conditions. Both studies therefore include investigations on the modernenvironment (including organisms, soils, rocks, lake water and sediments).

description: In der Schweiz stehen rund 450 Reisebusunternehmen im Dienst von Bevölkerung und Tourismus. Sie betreiben rund 2’900 Reisebusse (Cars, Reisecars) und bedienen damit jährlich gegen 10,4 Millionen Fahrgäste. Kleine (20%) und mittlere (66%) Unternehmen dominieren die Branche; nur 1% aller Unter-nehmen verfügen über mehr als 20 Cars.

Für die Ermittlung der Wertschöpfung und der Beschäftigung wurden die direkte, die indirekte und die induzierte Wertschöpfung berücksichtigt. Die Schweizer Reisebusbranche erarbeitet im Inland einen Jahresumsatz von CHF 944 Millionen und eine Bruttowertschöpfung von rund CHF 782 Millionen. Würden der Incoming-Tourismus, die Ausgaben der Fahrgäste und die Fahrten ins Ausland ebenfalls hinzugerechnet, wäre sogar mit einem Mehrfachen zu rechnen. Gleichzeitig sind die Schweizer Reise-busunternehmen wichtige Arbeitgeber. Sie sorgen für rund 4’900 Stellen (Vollzeitäquivalente). Ange-sichts der hohen Anteile von Teilzeitmitarbeitenden dürfte die Anzahl der tatsächlichen Mitarbeitenden deutlich darüber liegen.

In Zukunft werden angesichts der Verlagerung Richtung Pauschalreisen und des hohen Kostendrucks in der Branche insbesondere die kleinen Unternehmen gefordert sein. Für sie wird es immer wichtiger, die Bereiche Marketing und Administration weiterzuentwickeln, ihre Auslastung weiter zu steigern und ihre Produkte laufend zu erneuern.

A probabilistic view on rupture predictability: all earthquakes evolve similarly

description: Ruptures of the largest earthquakes can last between a few seconds and several minutes. An early assessment of the final earthquake size is essential for early warning systems. However, it is still unclear when in the rupture history this final size can be predicted. Here we introduce a probabilistic view of rupture evolution - how likely is the event to become large - allowing for a clear and well-founded answer with implications for earthquake physics and early warning. We apply our approach to real time magnitude estimation based on either moment rate functions or broadband teleseismic P arrivals. In both cases, we find strong and principled evidence against early rupture predictability because differentiation between differently sized ruptures only occurs once half of the rupture has been observed. Even then, it is impossible to foresee future asperities. Our results hint towards a universal initiation behavior for small and large ruptures.

description: The measurement of the triple Higgs coupling is one of the main tasks of the (HL-)LHC and future lepton colliders. Similarly, triple Higgs couplings involving BSM Higgs bosons are of high interest. Within the framework of Two Higgs Doublet Models (2HDM) we investigate the allowed ranges for all triple Higgs couplings involving at least one light, SM-like Higgs boson. We present newly the allowed ranges for 2HDM type III and IV and update the results within the type I and II. We take into account theoretical constraints from unitarity and stability, experimental constraints from direct BSM Higgs-boson searches, measurements of the rates of the SM-like Higgs-boson at the LHC, as well as flavor observables and electroweak precision data. For the SM-type triple Higgs coupling w.r.t. its SM value, $λ_{hhh}/λ_{hhh}^\mathrm{SM}$, we find allowed intervals of $\sim [-0.5,1.3]$ in type~I and $\sim [0.5,1.0]$ in the other Yukawa types. These allowed ranges have important implications for the experimental determination of this coupling at future collider experiments. We find the coupling $λ_{hhH}$ between $\sim -1.5$ and $\sim +1.5$ in the four Yukawa types. For the triple Higgs couplings involving two heavy neutral Higgs bosons, $λ_{hHH}$ and $λ_{hAA}$ we find values between $\sim -0.5$ and $\sim 16$, and between $\sim -1$ and $\sim 32$ for $λ_{hH^+H^-}$. These potentially large values could lead to strongly enhanced production of two Higgs-bosons at the HL-LHC or high-energy lepton colliders.

description: Juxtacolopodacus n. gen.
Body elongate, robust anteriorly with a broad dorsopropodosomal shield; shield with a pronounced narrow frontal lobe. Prodorsal shield setiferous tubercles on far lateral shield margin; scapular seta probably pointing divergently backwards. Opisthosoma with rings about even in numbers dorsoventrally; with three dorsal ridges: middorsal ridge strong, fades into a trough; lateral ridges well defined, extend over entire opisthosomal length. Coxae I separated medially; all three coxal setae present. Femoral seta on leg I absent; all other leg setae present. Tarsus on leg I with solenidion laterad to empodium.
Type species. Juxtacolopodacus phalakros n. sp.
Etymology. Juxta, Latin, near, next to + Colopodacus, that is, a genus near Colopodacus Keifer, 1960. Gender masculine.
Assignment and diagnosis. Eriophyidae, Nothopodinae, Colopodacini.
In Amrine et al. (2003) the new genus will key out to a position intermediate, but separate both from Colopodacus Keifer, 1960 and Apontella Boczek & Nuzzaci, 1988. It is similar to Apontella in the lack of femoral seta on leg I and in having reduced scapular setae on the far lateral shield margin, but differs from Apontella in having a middorsal opisthosomal ridge (Apontella has a middorsal trough), by the pronounced narrow frontal lobe (broad and rounded in Apontella) and in the lateral position of the solenidion on tarsus of leg I (solenidion dorsal in Apontella). It shares with Colopodacus the middorsal opisthosomal ridge, a narrow frontal lobe and separate coxae I, but differs in the lateral position of the solenidion on tarsus I (dorsal in Colopodacus), tibio-tarsus short and with dorsal and lateral setae in usual position (tibio-tarsus elongate and setae near the genu in Colopodacus), and in the far lateral position of the scapular setae (medially placed in Colopodacus).

description: A long, narrow, relativistic charged particle bunch propagating in plasma is subject to the self-modulation (SM) instability. We show that SM of a proton bunch can be seeded by the wakefields driven by a preceding electron bunch. SM timing reproducibility and control are at the level of a small fraction of the modulation period. With this seeding method, we independently control the amplitude of the seed wakefields with the charge of the electron bunch and the growth rate of SM with the charge of the proton bunch. Seeding leads to larger growth of the wakefields than in the instability case.

description: Fano effect arising from interference between two dissipation channels to the radiation continuum enables to tune the photon statistics. Understanding the role of Fano effect and exploiting to achieve strong photon correlations are of both fundamental and applied significance. We present an analytical description of Fano-enhanced photon correlations based on cavity quantum electrodynamics to show that, the Fano effect in atom-cavity systems can improve the degree of antibunching by over four orders of magnitude. The enhancement factors and the optimal conditions are explicitly given, and found related to the Fano parameter $q$. Remarkably, the Fano enhancement manifests robustness against the decoherence processes, and can survive in the weak coupling regime. We expect our work to provide insight in tuning the photon statistics through Fano effect, which offers a new route to enhance the photon correlations, as well as the possibility of generating nonclassical light in a wider diversity of systems without the need of strong light-matter interaction.

description: The formation of clusters at sub-saturation densities constitutes an essential feature for a reliable modelization of the nuclear matter equation of state (EoS). Phenomenological models that make use of energy density functionals (EDFs) offer a convenient approach to account for the presence of these bound states of nucleons when introduced as additional degrees of freedom. However, in these models clusters dissolve, by construction, when the nuclear saturation density is approached from below, revealing inconsistencies with recent findings that evidence the existence of short-range correlations (SRCs) even at larger densities. In this work, within the EDF framework, a novel approach is proposed to embed SRCs within a relativistic mean-field model with density dependent couplings. This is realized through the introduction of suitable in-medium modifications of the cluster binding energy shifts, which are responsible for describing the cluster dissolution. As a first exploratory step, the example of a quasi-deuteron within the generalized relativistic density functional approach is investigated. For the first time, suitable parameterizations of the cluster mass shift at zero temperature are derived for all baryon densities. They are constrained by experimental results for the effective deuteron fraction in nuclear matter near saturation and by microscopic many-body calculations in the low-density limit. The strength of the deuteron-meson couplings is assessed to be of crucial importance. The findings of the present study represent a first step to improve the description of nuclear matter and its EoS at supra-saturation densities in EDFs by considering correlations in an effective way. Novel effects on some thermodynamic quantities, such as the matter incompressibility, the symmetry energy and its slope, are finally discerned and discussed.

description: Dark matter and inflation are two key elements to understand the origin of cosmic structures in modern cosmology, and yet their exact physical models remain largely uncertain. The Weyl scaling invariant theory of gravity may provide a feasible scheme to solve these two puzzles jointly, which contains a massive gauge boson playing the role of dark matter candidate, and allows the quadratic scalar curvature term, namely $R^2$, to realize a viable inflationary mechanism in agreement with current observations. We ponder on the production of dark matters in the Weyl $R^2$ model, including the contribution from the non-perturbative production due to the quantum fluctuations from inflationary vacuum and perturbative ones from scattering. We demonstrate that there are generally three parameter ranges for viable dark matter production: (1) If the reheating temperature is larger than $10^3~\mathrm{GeV}$, the Weyl gauge boson as dark matter can be produced abundantly with mass larger than the inflation scale $\sim 10^{13}~\mathrm{GeV}$. (2) Small mass region with $3\times10^{-13}~\mathrm{GeV}$ for a higher reheating temperature. (3) Annihilation channel becomes important in the case of higher reheating temperature, which enables the Weyl gauge boson with mass up to $4\times10^{16}~\mathrm{GeV}$ to be produced through freeze-in.

description: Overlap fermion on the lattice has been shown to properly reproduce topological aspects of gauge fields. In this paper, we review the derivation of Overlap fermion formalism in a torus of three space-time dimensions. Using the formalism, we show how to use the Overlap fermion determinants in the massless and infinite mass limits to construct different continuum topological gauge actions, such as the level-$k$ Chern-Simons action, ``half-CS" term and the mixed Chern-Simons (BF) coupling, in a gauge-invariant lattice UV regulated manner. Taking special Abelian and non-Abelian background fields, we demonstrate numerically how the lattice formalism beautifully reproduces the continuum expectations, such as the flow of action under large gauge transformations.

description: The ionosphere is a part of the upper atmosphere stretching from a height of about 60 km to more than 1 000 km. A certain fraction of the gas particles in that region is ionised by solar extreme ultra violet radiation. Since electromagnetic waves are influenced and significantly modified by ionospheric free charge carriers, the altitude range is of great scientific interest. GPS satellites emit electromagnetic waves on L – band frequencies travelling through the ionosphere and lower neutral atmosphere. Subsequently, they are received by low–Earth orbiting satellites. Consequently, the signals are affected by strong electron density gradients at altitudes above approximately 80km and by atmospheric density, pressure and water vapour content in the troposphere and stratosphere. This measurement method is termed radio occultation technique and it allows to receive a global picture of ionospheric and lower neutral atmospheric conditions. This study focusses on the detection and analysis of sporadic E layers from GPS radio occultation measurements on a global scale. Sporadic E layers are localised patches of relatively high electron density appearing in the E region of the ionosphere. They are represented in GPS signals as intense fluctuations. This work reveals that global sporadic E occurrence rates underlie variations on different time scales. It is demonstrated that the sporadic E occurrence depends on several geophysical parameters and it is subject to coupling processes between the neutral atmosphere and ionosphere. For example, the global sporadic E occurrence is oriented along Earth’s magnetic field. It is shown additionally that sporadic E altitudes are subject to tidal winds and that its annual cycle varies with meteor influx.

The name Scolotosus, illustration and description first appeared in a Thesis by Flechtmann (1971). Since a Thesis cannot be considered a publication, the name Scolotosus, as well as that of S. centrolobii, its type species, cannot be considered as published for nomenclatural purposes.
Amrine et al. (2003), although citing Scolotosus and S. centrolobii and giving its illustration, in not explicitly indicating these as intentionally new and not designating type specimens, did not make these names available and must, therefore, be considered nomina nuda. The description of the genus and its type species, as written in 1971 by Flechtmann & Keifer (in Flechtmann, 1971), are herein presented.
Assignment and diagnosis – Eriophyidae, Phyllocoptinae, Tegonotini.
Moderately slender tapering species, widest anteriorly with abruptly anterior end and shield. Shield with short anterior lobe over rostrum base. Dorsal tubercles on rear shield margin, projecting short setae divergently to rear. Rostrum small, with short form of oral stylet. Legs and coxae with standard setation and form. Abdomen [opisthosoma] with rather wide tergal-sternal rings which are equal dorso-ventrally. Each abdominal ring [opisthosomal annulus] with a row of spines completely encircling body toward rear of ring. Middorsal longitudinal ridge on thanosome [anterior opisthosoma], fading toward telosome [caudal opisthosoma]; lateral thanosomal [anterior opisthosomal] ridge or series of projecting lobes from dorsal tubercles, also fading toward telosome [caudal opisthosoma]. Spines on ridge and lobes tending to be larger. Thanosome and telosome [opisthosoma] with all standard setae. Female genitalia as usual, with internal anterior apodeme of moderate length.
Type species. Scolotosus centrolobii n. sp.
Etymology. Scolos, a Greek word meaning spine; Tosus, a Greek word meaning too much. Gender masculine.
Remarks. In a sense this genus is very close to Tegonotus spp., genotype heptacanthus (Nal.), but the character of the lateral lobes is quite different from the older genus, and the circles of spines is unlike Tegonotus. The form of the shield does not resemble Tegonotus spp.

description: Most measurements in particle and nuclear physics use matrix-based unfolding algorithms to correct for detector effects. In nearly all cases, the observable is defined analogously at the particle and detector level. We point out that while the particle-level observable needs to be physically motivated to link with theory, the detector-level need not be and can be optimized. We show that using deep learning to define detector-level observables has the capability to improve the measurement when combined with standard unfolding methods.

title: A global survey of sporadic E layers based on GPS radio occultations by CHAMP, GRACE and FORMOSAT–3 / COSMIC

description: The ionosphere is a part of the upper atmosphere stretching from a height of about 60 km to more than 1 000 km. A certain fraction of the gas particles in that region is ionised by solar extreme ultra violet radiation. Since electromagnetic waves are influenced and significantly modified by ionospheric free charge carriers, the altitude range is of great scientific interest.GPS satellites emit electromagnetic waves on L – band frequencies travelling through the ionosphere and lower neutral atmosphere. Subsequently, they are received by low–Earth orbiting satellites. Consequently, the signals are affected by strong electron density gradients at altitudes above approximately 80km and by atmospheric density, pressure and water vapour content in the troposphere and stratosphere. This measurement method is termed radio occultation technique and it allows to receive a global picture of ionospheric and lower neutral atmospheric conditions.This study focusses on the detection and analysis of sporadic E layers from GPS radiooccultation measurements on a global scale. Sporadic E layers are localised patches ofrelatively high electron density appearing in the E region of the ionosphere. They arerepresented in GPS signals as intense fluctuations.This work reveals that global sporadic E occurrence rates underlie variations on different time scales. It is demonstrated that the sporadic E occurrence depends on several geophysical parameters and it is subject to coupling processes between the neutral atmosphere and ionosphere. For example, the global sporadic E occurrence is oriented along Earth’s magnetic field. It is shown additionally that sporadic E altitudes are subject to tidal winds and that its annual cycle varies with meteor influx.
title: Evaluating and improving flood inundation forecasts using satellite data
Creators: name: Hooker, Helen

description: Flood inundation forecast maps provide an essential tool to disaster management teams
for planning and preparation ahead of a flood event in order to mitigate the impacts of
flooding. The maps can be used to inform forecast-based financing schemes to release
funds ahead of a predicted flood event. Evaluating the accuracy of forecast flood maps
is essential for model development and improving future flood predictions. The goal of
this thesis is to develop spatial verification methods for deterministic and ensemble flood
map forecasts and to improve forecasts using satellite data. Binary verification measures
typically provide a domain-averaged score of forecast skill. The skill score is dependent
on the magnitude of the flood and the spatial scale of the flood map. In this thesis, a new
scale-selective approach is presented to evaluate both deterministic and ensemble forecast
flood maps against remotely observed flood extents. The flood-edge location accuracy
proves to be more sensitive to variations in forecast skill and spatial scale compared to
the accuracy of the entire flood extent. Both the ensemble spatial-skill and spread-skill
relationship vary with location and can be linked to the physical characteristics of the
flooding event. We find that a scale-selective verification approach can quantify the skill
of three systems operating at different spatial scales, so that the benefits and limitations of
each system can be evaluated. A new data assimilation framework is presented to update
the flood map selection from a static library of flood maps using satellite data, taking
account of observation uncertainties. Results show that the flood map selection could be
triggered in four out of five sub-catchments tested. The resultant analysis flood map has
the potential to be used to trigger a secondary finance scheme during a flood event and
avoid missed financing opportunities for humanitarian action. Overall, sensitive spatial
verification methods that are location specific and can evaluate ensemble performance will
aid future model development for flood inundation prediction.

title: Earth's magnetic field : observation and modelling from global to regional scales
Creators: name: Geese, Anne
Publisher: name: Deutsches GeoForschungsZentrum GFZ
Year: 2011

description: The magnetic field of the Earth varies in space and time. Geomagnetism as research area that aims to describe and understand the sources of these variations is supported by two pillars: first, regular high-precision measurements in the global network of magnetic observatories and repeat stations are necessary to register the field and its variations at all. Second, mathematical methods are required in order to extract magnetic field models from this large data set. Methods applied to data offer insights in the mechanisms generating the magnetic field. This thesis covers both subjects. In a first part, following the description of the state of the art in observatory instrumentation, I explain in detail two instruments that have the potential to streamline the classical procedures: The Geomagnetic AUtomated SyStem GAUSS paves the way to automated absolute measurements, up to now only possible manually. The newly developed DI3 technique improves and simplies the standard manual measurements signicantly and thus reduces the requirements placed on observers. The second part deals with the mathematical tools available for geomagnetic field modelling. I focus on harmonic splines that can be derived from the classical approach of spherical harmonics. These base functions are interpolatory and have a localised shape while satisfying Laplaces equation. Hence, they are applicable to fit data regionally or globally. The harmonic splines are used with a data set made of repeat station and observatory measurements from Southern Africa. This region is of special interest because the field intensity is very low and and both spatial and temporal field gradients exist. Subdivided into an analysis of ancient (years 1961-2001) and recent (2005-2009) data, two continuous regional field models SAMS and X-SAMS are derived. From the analysis of the field models, a better understanding of the field behaviour is gained. Finally, the harmonic splines are used in a case study on globally distributed secular variation data. Rotating the data set in a system of coordinates aligned with the dipole axis and modelling it with the harmonic splines reveals the external origin of observed fast variations.

description: Removing distortions in coherent anti-Stokes Raman scattering (CARS) spectra due to interference with the nonresonant background (NRB) is vital for quantitative analysis. Popular computational approaches, the Kramers-Kronig relation and the maximum entropy method, have demonstrated success but may generate significant errors due to peaks that extend in any part beyond the recording window. In this work, we present a learned matrix approach to the discrete Hilbert transform that is easy to implement, fast, and dramatically improves accuracy of Raman retrieval using the Kramers-Kronig approach.

description: This work focuses on the low frequency Drude response of bulk-insulating topological insulator Bi$_2$Se$_3$ films. The frequency and field dependence of the mobility and carrier density are measured simultaneously via time-domain terahertz spectroscopy. These films are grown on buffer layers, capped by Se, and have been exposed in air for months. Under a magnetic field up to 7 Tesla, we observe prominent cyclotron resonances (CRs). We attribute the sharp CR to two different topological surface states (TSSs) from both surfaces of the films. The CR sharpens at high fields due to an electron-impurity scattering. By using magneto-terahertz spectroscopy, we confirm that these films are bulk-insulating, which paves the way to use intrinsic topological insulators without bulk carriers for applications including topological spintronics and quantum computing.
