description: We study the entanglement entropy between the two outgoing particles in an elastic scattering process. It is formulated within an S-matrix formalism using the partial wave expansion of two-body states, which plays a significant role in our computation. As a result, we obtain a novel formula that expresses the entanglement entropy in a high energy scattering by the use of physical observables, namely the elastic and total cross sections and a physical bound on the impact parameter range, related to the elastic differential cross-section.

description: Spanish quality assurance agencies, both state-owned (Aneca and AEI, State Research Agency, which evaluates research projects) and regional (AQU, ACSUCyL, DEVA, etc.) have made some progress on modifying the current model for research assessment, which is mainly based on the journal impact factor (JIF). These are timid advances that are evidenced by the adherence to international declarations, especially DORA, and to the COARA coalition. Objective: The general objective of the study is to understand the perception of the directors of Spanish quality assurance agencies regarding the introduction of new indicators for research assessment. Methodology: An online survey was conducted divided into five blocks of questions with responses recorded on a five-point Likert scale to understand the agencies' opinions regarding: - New indicators to evaluate scholarly publications - The implementation of new indicators and research assessment models. - The barriers that hinder the introduction of new indicators and research assessment models - The elements that favour the introduction of new indicators and research assessment models - Who should drive the change in the model and the actions taken so far The questionnaire was sent to the leaders of the 14 Spanish agencies identified, both state-owned and regional. Results: The agency's leaders highlight qualitative evaluations and downloads as alternative or complementary indicators to the current model. They do not give excessive importance to the impact factor, citations of articles, or altmetrics. The main barrier to maintaining the current model would be the immobility of the administration since the agency's leaders consider that both evaluators and researchers would not have such an opposing position. The change in the evaluation model should be driven, first, by the ministries of universities and science and then by the university's rector teams. The agency's leaders see themselves as the third level of responsibility in this matter.
Fading Out, Fading In: Investigating the Relations Between Epilepsy, Electronic Music, and Gender

description: This thesis identifies and responds to feminist, social and historic questions concerning epilepsy by drawing on music as a mode of enquiry, thus producing new knowledge in the field of disability studies. It argues that epilepsy is a “minded” as well as a bodily phenomenon that can be understood through music analysis, including metaphor, figure and myth. Epilepsy is a phenomenon that is, in part, experiential and characterised by inconsistency. A key tension I explore arises between a need for the epileptic to find a sense of lived continuity, and theories that suggest subjectivity is always fragmented, emerging in relation to language and context. Due to this, investigating epilepsy calls for a multi-modal approach that can make sense of both the social history of sexism and violence that informs our understanding of epilepsy, as well as its subjective experience, such as its chronicity in the present. Case studies in the thesis synthesise electronic music practice, feminist theory, and Foucauldian genealogy in order to formulate a novel analytical framework. By refiguring epilepsy at a feminist theoretical juncture and by elaborating questions of feminine sonic aesthetics, the research, moreover, suggests new ways of conceptualising and practising music. This has implications for disability studies and the arts. A key point of departure for the research is my own subject position and this reflects on the difficulty and embodied experience of creating and performing as a musician with epilepsy.

description: One of the advantages of adopting a Model Based Development (MBD) process is that it enables testing and verification at early stages of development. However, it is often desirable to not only verify/falsify certain formal system specifications, but also to automatically explore the properties that the system satisfies. In this work, we present a framework that enables property exploration for Cyber-Physical Systems. Namely, given a parametric specification with multiple parameters, our solution can automatically infer the ranges of parameters for which the property does not hold on the system. In this paper, we consider parametric specifications in Metric or Signal Temporal Logic (MTL or STL). Using robust semantics for MTL, the parameter mining problem can be converted into a Pareto optimization problem for which we can provide an approximate solution by utilizing stochastic optimization methods. We include algorithms for the exploration and visualization of multi-parametric specifications. The framework is demonstrated on an industrial size, high-fidelity engine model as well as examples from related literature.

description: An der Nordgrenze Eisenhüttenstadts, dicht am Ufer der vorbeifließenden Oder, erhebt sich die Ruine des in den letzten beiden Jahren des Zweiten Weltkriegs errichteten Kraftwerks Vogelsang . Das Bauprojekt wurde unter Einsatz von Kriegsgefangenen, jüdischen KZ-Häftlingen und zivilen Zwangsarbeitern eilig vorangetrieben. Es war Bestandteil eines 1942 aufgelegten Programms zum Bau von Typenkraftwerken und entstand im Zusammenhang mit dem forcierten Ausbau der Kriegswirtschaft in der Region. Bei Kriegsende wurde das Kraftwerk zum Schauplatz intensiver Kampfhandlungen. Anfang Februar 1945 bildete die Rote Armee hier einen Brückenkopf. Von der Erstürmung des Kraftwerkskomplexes zeugen heute die zahlreichen Granatdurchschläge an seiner Ostflanke. Das Kraftwerk ging nie ans Netz. Durch die sowjetische Besatzungsmacht demontiert, diente seine Ruine in der DDR nur noch als Kulisse für paramilitärische Übungen. Der im Jahre 1998 begonnene Abbruch wurde aus ökologischen Gründen (Lebensraum für Fledermäuse und seltene Vogelarten) vorübergehend gestoppt.

description: We consider symmetry protected topological (SPT) phases with crystalline point group symmetry, dubbed point group SPT (pgSPT) phases. We show that such phases can be understood in terms of lower-dimensional topological phases with on-site symmetry, and can be constructed as stacks and arrays of these lower-dimensional states. This provides the basis for a general framework to classify and characterize bosonic and fermionic pgSPT phases, that can be applied for arbitrary crystalline point group symmetry and in arbitrary spatial dimension. We develop and illustrate this framework by means of a few examples, focusing on three-dimensional states. We classify bosonic pgSPT phases and fermionic topological crystalline superconductors with $Z_2^P$ (reflection) symmetry, electronic topological crystalline insulators (TCIs) with ${\rm U}(1) \times {Z}_2^P$ symmetry, and bosonic pgSPT phases with $C_{2v}$ symmetry, which is generated by two perpendicular mirror reflections. We also study surface properties, with a focus on gapped, topologically ordered surface states. For electronic TCIs we find a $Z_8 \times Z_2$ classification, where the $Z_8$ corresponds to known states obtained from non-interacting electrons, and the $Z_2$ corresponds to a "strongly correlated" TCI that requires strong interactions in the bulk. Our approach may also point the way toward a general theory of symmetry enriched topological (SET) phases with crystalline point group symmetry.

Confinement/deconfinement transition from symmetry breaking in gauge/gravity duality

description: We study the confinement/deconfinement transition in a strongly coupled system triggered by an independent symmetry-breaking quantum phase transition in gauge/gravity duality. The gravity dual is an Einstein-scalar-dilaton system with AdS near-boundary behavior and soft wall interior at zero scalar condensate. We study the cases of neutral and charged condensate separately. In the former case the condensation breaks the discrete $\mathbb{Z}_2$ symmetry while a charged condensate breaks the continuous $U(1)$ symmetry. After the condensation of the order parameter, the non-zero vacuum expectation value of the scalar couples to the dilaton, changing the soft wall geometry into a non-confining and anisotropically scale-invariant infrared metric. In other words, the formation of long-range order is immediately followed by the deconfinement transition and the two critical points coincide. The confined phase has a scale -- the confinement scale (energy gap) which vanishes in the deconfined case. Therefore, the breaking of the symmetry of the scalar ($\mathbb{Z}_2$ or $U(1)$) in turn restores the scaling symmetry in the system and neither phase has a higher overall symmetry than the other. When the scalar is charged the phase transition is continuous which goes against the Ginzburg-Landau theory where such transitions generically only occur discontinuously. This phenomenon has some commonalities with the scenario of deconfined criticality. The mechanism we have found has applications mainly in effective field theories such as quantum magnetic systems. We briefly discuss these applications and the relation to real-world systems.

description: In this work we study a non-linear generalization based on affine transformations of probabilistic and quantum automata proposed recently by Díaz-Caro and Yakaryılmaz \cite{DCY16A} referred as affine automata. First, we present efficient simulations of probabilistic and quantum automata by means of affine automata which allows us to characterize the class of exclusive stochastic languages. Then, we initiate a study on the succintness of affine automata. In particular, we show that an infinite family of unary regular languages can be recognized by 2-state affine automata but the state numbers of quantum and probabilistic automata cannot be bounded. Finally, we present the characterization of all (regular) unary languages recognized by two-state affine automata.

Compressed Dynamic Mode Decomposition for Background Modeling

description: We introduce the method of compressed dynamic mode decomposition (cDMD) for background modeling. The dynamic mode decomposition (DMD) is a regression technique that integrates two of the leading data analysis methods in use today: Fourier transforms and singular value decomposition. Borrowing ideas from compressed sensing and matrix sketching, cDMD eases the computational workload of high resolution video processing. The key principal of cDMD is to obtain the decomposition on a (small) compressed matrix representation of the video feed. Hence, the cDMD algorithm scales with the intrinsic rank of the matrix, rather then the size of the actual video (data) matrix. Selection of the optimal modes characterizing the background is formulated as a sparsity-constrained sparse coding problem. Our results show, that the quality of the resulting background model is competitive, quantified by the F-measure, Recall and Precision. A GPU (graphics processing unit) accelerated implementation is also presented which further boosts the computational efficiency of the algorithm.

description: It is shown that in the spin-charge-family theory, as well as in all the Kaluza-Klein like theories, vielbeins and spin connections manifest in $d=(3+1)$ space equivalent vector gauge fields, when space with $d\ge5$ manifests large enough symmetry. The authors demonstrate this equivalence in spaces with the symmetry of the metric tensor in the space out of $d=(3+1)$ - $g^{στ} = η^{στ} \,f^{2}$ - for any scalar function $f$ of the coordinates $x^σ$, where $x^σ$ denotes coordinates of space out of $d=(3+1)$. Also the connection between vielbeins and scalar gauge fields in $d=(3+1)$ (offering the explanation for the Higgs's scalar) is discussed.

description: To predict the jet mass spectrum at a hadron collider it is crucial to account for the resummation of logarithms between the transverse momentum of the jet and its invariant mass $m_J$. For small jet areas there are additional large logarithms of the jet radius $R$, which affect the convergence of the perturbative series. We present an analytic framework for exclusive jet production at the LHC which gives a complete description of the jet mass spectrum including realistic jet algorithms and jet vetoes. It factorizes the scales associated with $m_J$, $R$, and the jet veto, enabling in addition the systematic resummation of jet radius logarithms in the jet mass spectrum beyond leading logarithmic order. We discuss the factorization formulae for the peak and tail region of the jet mass spectrum and for small and large $R$, and the relations between the different regimes and how to combine them. Regions of experimental interest are classified which do not involve large nonglobal logarithms. We also present universal results for nonperturbative effects and discuss various jet vetoes.

Rocky Planets at the substellar mass limit

description: Rocky planets located in the habitable zones around M-dwarfs are ideal targets for the search of life outside our Solar System. On the one hand, in order to better understand their formation and evolution, N-body simulations were developed. The central object was assumed to be a star close to the substellar mass limit. The simulations included tidal and general relativistic effects that incorporate the contraction and evolution of the rotational period of the central object during 100 Myr, as well as gas-disk interactions with a sample of protoplanetary embryos during the gas-disk lifetime. A very relevant result is that just one of the prescriptions used to treat the interactions between the gas-disk and the sample of embryos allows the survival of a close-in compact planet population of interest, located in the habitable zone of the systems with a wide range of masses from Mars-like planets up to Earth-like planets and close to commensurabilities. Moreover, the resulting planets with semi-major axis a < 0.1 au are in agreement with the cumulative distribution of period ratio of adjacent terrestrial-like exoplanets around stars with masses M < 0.14 Msun. On the other hand, in order to estimate the probability of detection of planetary systems around very low mass stars, a numerical tool in python was developed. This new tool calculates the changes in stellar flux, radial velocity and proper motion of a sample of stars due to the interaction with their planetary systems, and estimates the probability of detection of planetary systems regarding different samplings and errors associated with a given instrument or survey. A significant result is that the radial velocity method allows a high probability of planetary detection around very low mass stars, with the current and future technology.

We find two different solutions of the saddle point equations in the large N limit. With these solutions we compute the free energy and find that there is a first order phase transition. Our results may predict a phase transition in the dual gravity theory.

description: Low availability of manganese (Mn) induces its deficiency in wheat grown particularly in course textured soil. Growing Mn efficient and responsive genotypes on light textured soils is sustainable approach to higher Mn accumulation in wheat grain. For this, sixteen wheat genotypes viz. bread, durum and triticale, were investigated for two years with foliar application of Mn. Diverse wheat genotypes responded differently toward yield and quality parameters. Maximum increment in grain and straw yield was observed in PDW314 (39.3%) and TL2908 (26.1%), over control. On the other hand, Mn concentration in grain and straw increased to maximum in PDW 274 (51.3%) and PBW621 (51.2%), over control. Among bread, durum and triticale genotypes, PBW343U (61.8%), PDW274 (91%) and TL2969 (37.8%) strongly responded to Mn application and supported by higher Mn accumulation. Average grain yield efficiency index (GYEI) and Mn accumulation efficiency index (MAEI) were 89.0 and 71.7, respectively. Due to higher yield and higher Mn accumulation than GYEI and MAEI, the genotypes HD2967, PBW725, PBW677, PBWZn1, TL2969, PDW233 were categorized as efficient and responsive, which may prove beneficial for wheat production at large scale under Mn deficient soil. Additional supply of Mn also significantly improved the phenolic content, flavonoids content and total antioxidant activity, while reducing the tannins and phytate content in all genotypes. Based on obtained results, PBW677, PBWZn1 and TL2969 were screened as most desirable genotypes as they possess high GYEI, MAEI, high antioxidant activity and low antinutrient content.
Persisting of Polar Distortion with Electron Doping in Lone-Pair Driven Ferroelectrics

description: Free electrons can screen out long-range Coulomb interaction and destroy the polar distortion in some ferroelectric materials, whereas the coexistence of polar distortion and metallicity were found in several non-central-symmetric metals (NCSMs). Therefore, the mechanisms and designing of NCSMs have attracted great interests. In this work, by first-principles calculation, we found the polar distortion in the lone-pair driven ferroelectric material PbTiO$_3$ can not only persist, but also increase with electron doping. We further analyzed the mechanisms of the persisting of the polar distortion. We found that the Ti site polar instability is suppressed but the Pb site polar instability is intact with the electron doping. The Pb-site instability is due to the lone-pair mechanism which can be viewed as a pseudo-Jahn-Teller effect, a mix of the ground state and the excited state by ion displacement from the central symmetric position. The lone-pair mechanism is not strongly affected by the electron doping because neither the ground state or the excited state involved is at the Fermi energy. The enhancement of the polar distortion is related to the increasing of the Ti ion size by doping. These results show the lone-pair stereoactive ions can be used in designing NCSMs.

Subjects: Metals and alloy materials

description: The cryogenic processing of materials is an intriguing topic that has attracted attention over the past 80 years with the promise of a possible, often unexplained, improvement in the mechanical properties and performance of materials as a result of its application. A scientifically superficial treatment of the subject has fostered the establishment of erroneous beliefs that have grown over time making the field more of an alchemical subject, rather than a solid engineering disciple.
 The current collection of notes intends to illustrate all the research activity reported in the scientific literature on the subject up to 2011, and few more recent works, by sticking to the facts. My personal notes are included (and well distinguished from the fact) both to highlight scientifically relevant links, and to indicate situations where the most recent understanding of, in particular, the physical metallurgy of steel suggests the need for reinterpretation of the data.
 With the current sharing I intend to promote a culture in which one's scientific work is always organized to be of public interest and an open environment in which scientific literature is kept as accessible to the public as possible.

description: Brownian motion in R 2 + with covariance matrix $Σ$ and drift $μ$ in the interior and reflection matrix R from the axes is considered. The asymptotic expansion of the stationary distribution density along all paths in R 2 + is found and its main term is identified depending on parameters ($Σ$, $μ$, R). For this purpose the analytic approach of Fayolle, Iasnogorodski and Malyshev in [12] and [36], restricted essentially up to now to discrete random walks in Z 2 + with jumps to the nearest-neighbors in the interior is developed in this article for diffusion processes on R 2 + with reflections on the axes.

description: Understanding the human factors governing effective information exchange is increasingly indispensable for the design of day to day human-computer systems. Moreover, effective information exchange becomes a matter of life or death during emergency egress. The complexity of an unknown environment and the unpredictable locations of hazards often prevent evacuees from identifying safe routes. Successful evacuations from locations impacted by fire or earthquakes may depend on user-generated information to increase the chance of collective survival. The present paper employed multi-user virtual reality experiments and an online survey to investigate the mechanisms underlying social influence and collective intelligence during emergencies. Our results demonstrate that information sharing helps to reduce evacuation time and trajectory length. Participants also shared more when given incentives or when there was a lack of knowledge in the public information pool. This work provides further indications of how collective intelligence can be promoted and deployed during emergencies.

description: This thesis research is based on a qualitative research, taking its information from literature, articles and journals. The research was conducted to first examine and understand the importance of HR practices within the organization, specifically what they are, how they are implemented effectively and their contribution to the sustainability of the organization. It then examines the role of leadership and organizational culture in organizational performance in a challenging environment and the coordination of HR practices in value creation and subsequent competitive advantage. Concluding the research with an important strategic model which is the Employer Branding, that companies try to build to develop their digital presence, proving that it creates significant value to the company. Initially, the research evolves to identify the most important HR practices and gradually analyses each practice in the digital age and the impact that technological changes have on company's strategic advantage and subsequently on their sustainability. In the second part of the research, an extensive analysis is carried out on the role of culture and leadership in creating the company's competitive advantage. Research evolves into the role of leadership in the digital age and penetrates the benefits of innovation for its contribution to competitive advantage and company sustainability. The third part cumulatively explains the digital age in relation to HR and the challenges in the near future.

description: We use topological data analysis to study "functional networks" that we construct from time-series data from both experimental and synthetic sources. We use persistent homology with a weight rank clique filtration to gain insights into these functional networks, and we use persistence landscapes to interpret our results. Our first example uses time-series output from networks of coupled Kuramoto oscillators. Our second example consists of biological data in the form of functional magnetic resonance imaging (fMRI) data that was acquired from human subjects during a simple motor-learning task in which subjects were monitored on three days in a five-day period. With these examples, we demonstrate that (1) using persistent homology to study functional networks provides fascinating insights into their properties and (2) the position of the features in a filtration can sometimes play a more vital role than persistence in the interpretation of topological features, even though conventionally the latter is used to distinguish between signal and noise. We find that persistent homology can detect differences in synchronization patterns in our data sets over time, giving insight both on changes in community structure in the networks and on increased synchronization between brain regions that form loops in a functional network during motor learning. For the motor-learning data, persistence landscapes also reveal that on average the majority of changes in the network loops take place on the second of the three days of the learning process.

description: In dynamical systems with divided phase space, the vicinity of the boundary between regular and chaotic regions is often "sticky," that is, trapping orbits from the chaotic region for long times. Here, we investigate the stickiness in the simplest mushroom billiard, which has a smooth such boundary, but surprisingly subtle behaviour. As a measure of stickiness, we investigate P(t), the probability of remaining in the mushroom cap for at least time t given uniform initial conditions in the chaotic part of the cap. The stickiness is sensitively dependent on the radius of the stem r via the Diophantine properties of rho = (2/π) arccos r. Almost all rho give rise to families of marginally unstable periodic orbits (MUPOs) where P(t) ~ C/t, dominating the stickiness of the boundary. Here we consider the case where rho is MUPO-free and has continued fraction expansion with bounded partial quotients. We show that t^2 P(t) is bounded, varying infinitely often between values whose ratio is at least 32/27. When rho has an eventually periodic continued fraction expansion, that is, a quadratic irrational, t^2 P(t) converges to a log-periodic function. In general, we expect less regular behaviour, with upper and lower exponents lying between 1 and 2. The results may shed light on the parameter dependence of boundary stickiness in annular billiards and generic area preserving maps.

description: Gesundheitspolitische Bestrebungen haben im Bereich der zahnmedizinischen Prophylaxe unter anderem die Förderung der häuslichen Mundhygiene sowie Programme zur Kariesprophylaxe bei Risikogruppen im Rahmen der Gruppenprophylaxe zum Ziel. Daher wurden in zwei Studien unterschiedliche Programme zur Betreuung von Kariesrisikokindern untersucht. In drei weiteren Studien wurde die Wirksamkeit neu entwickelter manueller und elektrischer Zahnbürsten im Rahmen der häuslichen Mundhygiene untersucht. ·Studien zur Betreuung von Kariesrisikokindern a)Ein individualisiertes Programm mit vierteljährlich durchgeführten professionellen Zahnreinigungen und der Anwendung eines niedrig dosierten Fluoridlackes (0,1% Fluorid) zeigte nach zwei Jahren im Vergleich zu einer Kontrollgruppe keinen kariesprophylaktischen Effekt. Die Kinder waren zu Beginn neun Jahre alt. Die Maßnahmen fanden in der Zahnklinik statt. b)Bei Grundschülern ergab eine zweimal jährlich durchgeführte Touchierung der Zähne mit einem Lack mit 2,26% Fluorid eine Kariesreduktion von 37% (p
description: In these days, politics is aimed at enhancing dental prophylaxis by supporting non professional oral hygiene measures. In addition, special programs are promoted which focus on caries prevention in high risk groups as part of dental group prophylaxis. In two studies, therefore, the effectiveness of different programs for caries risk-children was examined. In three other studies, the effectiveness of newly developed manual and electrical toothbrushes was tested. ·Caries risk studies a)An individualized program with professional toothcleaning and the application of a low dose fluoride varnish (0.1% fluoride) was performed four times a year. After two years of implementation this program did not show a caries preventive effect when compared to a control group. b)In primary school children a high dose fluoride varnish (2.26% fluoride) was applicated two times a year over a period of four years. This was done in the school within the group prophylaxis. This measure resulted in a 37% caries reduction (p

description: We introduce a research framework for downscaling the predicted/simulated climate and atmospheric conditions as well as associated risk maps down to the 1x1 km (historic area) scale, merging them with geohazard maps and integrating them with site and structure specific multi-hazard vulnerability functions to determine the time-varying risk for historical cities. Applying atmospheric modelling for specific Climate Change (CC) scenarios at such refined spatial and time scales allows for an accurate quantitative impact assessment of the estimated micro-climatic and atmospheric stressors. The ambition of this work, performed under the framework of the HYPERION EU-funded project, is to produce a comprehensive tool to assess the threats of CC in tandem with other natural hazards, visualize the built heritage and cultural landscape under future climate scenarios, model the effects of different adaptation strategies, and ultimately prioritize any rehabilitation actions to best allocate funds in both pre- and post-event environments.

description: Light curves of solar-type stars often show gradual fluctuations due to rotational modulation by magnetic features (starspots and faculae) on stellar surfaces. Two quantitative measures of modulated light curves are employed as the proxies of magnetic activity for solar-type stars observed with Kepler telescope. The first is named autocorrelation index $i_{AC}$, which describes the degree of periodicity of the light curve, the second is the effective fluctuation range of the light curve $R_{eff}$, which reflects the depth of rotational modulation. The two measures are complementary and depict different aspects of magnetic activities on solar-type stars. By using the two proxies $i_{AC}$ and $R_{eff}$, we analyzed activity properties of two carefully selected solar-type stars observed with Kepler (Kepler ID: 9766237 and 10864581), which have distinct rotational periods (14.7 vs. 6.0 days). We also applied the two measures to the Sun for a comparative study. The result shows that both the measures can reveal cyclic activity variations (referred to as $i_{AC}$-cycle and $R_{eff}$-cycle) on the two Kepler stars and the Sun. For the Kepler star with the faster rotation rate, $i_{AC}$-cycle and $R_{eff}$-cycle are in the same phase, while for the Sun (slower rotator), they are in the opposite phase. By comparing the solar light curve with simultaneous photospheric magnetograms, it is identified that the magnetic feature that causes the periodic light curve during solar minima is the faculae of the enhanced network region, which can also be a candidate of magnetic features that dominate the periodic light curves on the two Kepler stars.

description: Das Bevölkerungswachstum und die wirtschaftliche Entwicklung von Schwellenländern sorgen für einen weltweiten Bauboom. Folglich herrscht Sandbedarf. Die ölreichen Anrainerstaaten des Persischen Golfes, die einen enormen Bauboom zu verzeichnen haben, können sich teure Sandimporte zur Lösung des Problems leisten, da Wüstensand nicht zur Betonherstellung geeignet ist. Die Bauwirtschaft bedient sich am Meeresboden - nicht nur eine ökologische Zeitbombe: In Staaten wie Indien spricht man bereits von einer "Sandmafia", die sich blutige Bandenkriege und Verteilungskämpfe mit hunderten Toten um die begehrte Ressource liefert. Verteilungskonflikte, aufgrund der räumlich unausgeglichenen Ausstattung mit der begehrten Ressource, sind bereits heute zu beobachten, und bieten Zündstoff v.a. für regionale sowie zwischenstaatliche Konflikte. Sowohl in ökologischer und wirtschaftlicher als auch insbesondere in politischer Hinsicht identifiziert die Geopolitische Information verschiedene Faktoren, die zu Interessenskonflikten oder Spannungen im Zuge der Nutzung von Sand führen könnten.
description: The growing population and economic development of newly industrialized countries result in a worldwide construction boom, hence a demand for sand. The states bordering on the Persian Gulf that are rich in oil and experience an immense construction boom are able to afford expensive sand imports to solve their problem because desert sand is unsuitable for concrete production. The construction industry uses the sea floor which is more than just an ecological time bomb: states like India are already talking about a “sand Mafia” that engages in a bloody gang warfare and struggles for the coveted resource, leaving hundreds dead. Distribution conflicts due to the imbalanced spread of the resource in the area can already be observed and provide fuel for regional and intergovernmental conflicts in particular. The Geopolitical Information identifies several factors that may lead to conflicts of interests or tensions regarding the use of sand from both ecological and economic as well as political points of view.

description: The half filled Landau level is expected to be approximately particle-hole symmetric, which requires an extension of the Halperin-Lee-Read (HLR) theory of the compressible state observed at this filling. Recent work indicates that, when particle-hole symmetry is preserved, the composite Fermions experience a quantized $π$-Berry phase upon winding around the composite Fermi-surface, analogous to Dirac fermions at the surface of a 3D topological insulator. In contrast, the effective low energy theory of the composite fermion liquid originally proposed by HLR lacks particle-hole symmetry and has vanishing Berry phase. In this paper, we explain how thermoelectric transport measurements can be used to test the Dirac nature of the composite Fermions by quantitatively extracting this Berry phase. First we point out that longitudinal thermopower (Seebeck effect) is non-vanishing due to the unusual nature of particle hole symmetry in this context and is not sensitive to the Berry phase. In contrast, we find that off-diagonal thermopower (Nernst effect) is directly related to the topological structure of the composite Fermi surface, vanishing for zero Berry phase and taking its maximal value for $π$ Berry phase. In contrast, in purely electrical transport signatures the Berry phase contributions appear as small corrections to a large background signal, making the Nernst effect a promising diagnostic of the Dirac nature of composite fermions.
