description: Five-coordinate Cu(II) complexes, [Cu(Ln)X]ClO4/PF6, where Ln = piperazine ligands bearing two pyridyl arms and X = ClO4− for Ln = L1 (1-ClO4), L2 (2-ClO4), L3 (3-ClO4), and L6 (6-ClO4) as well as [Cu(Ln)Cl]PF6 for Ln = L1 (1-Cl), L4 (4-Cl), and L5 (5-Cl) have been synthesized and characterized by spectroscopic techniques. The molecular structures of the last two complexes were determined by X-ray crystallography. In aqueous acetonitrile solutions, molar conductivity measurements and UV-VIS spectrophotometric titrations of the complexes revealed the hydrolysis of the complexes to [Cu(Ln)(H2O)]2+ species. The biological activity of the Cu(II) complexes with respect to DNA cleavage and cytotoxicity was investigated. At micromolar concentration within 2 h and pH 7.4, DNA cleavage rate decreased in the order: 1-Cl ≈ 1-ClO4 > 3-ClO4 ≥ 2-ClO4 with cleavage enhancements of up to 23 million. Complexes 4-Cl, 5-Cl, and 6-ClO4 were inactive. In order to elucidate the cleavage mechanism, the cleavage of bis(4-nitrophenyl)phosphate (BNPP) and reactive oxygen species (ROS) quenching studies were conducted. The mechanistic pathway of DNA cleavage depends on the ligand’s skeleton: while an oxidative pathway was preferable for 1-Cl/1-ClO4, DNA cleavage by 2-ClO4 and 3-ClO4 predominantly proceeds via a hydrolytic mechanism. Complexes 1-ClO4, 3-ClO4, and 5-Cl were found to be cytotoxic against A2780 cells (IC50 30–40 µM). In fibroblasts, the IC50 value was much higher for 3-ClO4 with no toxic effect.

description: Interactions between emitters within an ensemble can give rise to cooperative processes that significantly alter the properties of the emitted light. One such process is superfluorescence (SF), where excited electric dipoles spontaneously couple coherently and effectively radiate as one macroscopic emitter. It requires low energetic disorder, high temporal coherence and oscillator strength, and sub-wavelength volumes of material can be sufficient. Conversely, amplified spontaneous emission (ASE) originates from an avalanche-like stimulated amplification of initially spontaneously emitted photons and does not necessitate temporally coherent interactions among the emitters, but rather requires spatially long enough light propagation within the material to harvest the optical gain. Cesium lead halide perovskite nanocrystals (NCs) are one of the very few materials where both ASE (in disordered films) and SF (in ordered assemblies) were observed, however leaving unclear whether and how these regimes could be connected. Here, we demonstrate that temperature and excitation density can drive the transition between both regimes in a thin film of giant CsPbBr3 perovskite NCs. At temperatures below 45 K, excitonic SF was observed, whereas above a transition range between 45 K and 100 K, ASE prevails, but requires increased optical excitation and emitter density. Our results work out the different collective effects present in lead halide perovskites, providing fundamental insights into cooperative phenomena and important guidance for the development of compact and bright (quantum) light sources.

description: The use of a foreign metallic cold source (CS) has recently been proposed as a promising approach toward the steep-slope field-effect-transistor (FET). In addition to the selection of source material with desired density of states-energy relation (D(E)), engineering the source: channel interface for gate-tunable channel-barrier is crucial to a CS-FET. However, conventional metal: semiconductor (MS)-interfaces generally suffer from strong Fermi-level-pinning due to the inevitable chemical disorder and defect-induced gap states, precluding the gate-tunability of the barriers. By comprehensive materials and device modeling at the atomic-scale, we report that the two-dimensional (2D)-van der Waals (vdW)-MS-interfaces, with their atomic sharpness and cleanness, can be considered as general ingredients for CS-FETs. As test cases, InSe-based n-type FETs are studied. It is found that graphene can be spontaneously p-type doped along with slightly opened bandgap around the Dirac-point by interfacing with InSe, resulting in super-exponentially decaying hot carrier density with increasing n-type channel-barrier. Moreover, the D(E) relations suggest that 2D-transition-metal-dichalcogenides and 2D-transition-metal-carbides are rich libraries of CS materials. Both graphene and H-TaTe2 CSs lead to subthreshold swing below 60 mV/decade. This work broadens the application potentials of 2D-vdW-MS-heterostructures and serves as a springboard for more studies on low-power electronics based on 2D materials.

description: The cooperative sector is an indispensable and integral part of the global economy; includes cooperatives ranging from small-scale to multi-million dollar businesses in all sectors of the economy, count over 800 million members and provide 100 million jobs – which is 20 percent more than multinational company. According to ICA Global 300 list, the largest 300 cooperatives in the world generate revenue of 1,600 billion US dollars (2010), which is comparable to the GDP of the Russian Federation or Spain and occupies the ninth place among the world's largest economies. The paper analyze the contribution of cooperatives to the development of international trade in agricultural and food products, starting from agricultural cooperatives which organized small farmers and involve them in local, national and world trade, to the consumer cooperatives that have managed to survive in spite of strong competition and increasing prices of agricultural and food products and the global economic crisis, and which significantly contribute to the international trade fair. The paper consists of two parts. In the first part is given the analysis of the contribution of the largest cooperatives in the world according to the list by Global 300 list, with special emphasis on the importance of agricultural cooperatives in the local economy, both in terms of reducing unemployment, as well as in the production of agricultural and food products. In the second part of the paper is presented the genesis of the development of a major international cooperative trade event – ICA Expo-Coop, which is a cooperative international fair that was held eight times in the period since 2004 to 2012. Based on the development of this international manifestation, the number of cooperatives exhibitors and visitors, and other important information, it is possible to observe how cooperatives participate and promote the development of international trade of agricultural and food products. It was particularly emphasized that the cooperative sector and ICA Expo-Coop are not adequately recognized and represented in the activities of the WTO after the Doha round.

description: The reduction of high-dimensional systems to effective models on a smaller set of variables is an essential task in many areas of science. For stochastic dynamics governed by diffusion processes, a general procedure to find effective equations is the conditioning approach. In this paper, we are interested in the spectrum of the generator of the resulting effective dynamics, and how it compares to the spectrum of the full generator. We prove a new relative error bound in terms of the eigenfunction approximation error for reversible systems. We also present numerical examples indicating that, if Kramers–Moyal (KM) type approximations are used to compute the spectrum of the reduced generator, it seems largely insensitive to the time window used for the KM estimators. We analyze the implications of these observations for systems driven by underdamped Langevin dynamics, and show how meaningful effective dynamics can be defined in this setting.
On the r-mode spectrum of relativistic stars: Inclusion of the radiation reaction

description: We consider both mode calculations and time evolutions of axial r-modes for relativistic uniformly rotating non-barotropic neutron stars, using the slow-rotation formalism, in which rotational corrections are considered up to linear order in the angular velocity Ω. We study various stellar models, such as uniform density models, polytropic models with different polytropic indices n, and some models based on realistic equations of state. For weakly relativistic uniform density models, and polytropes with small values of n, we can recover the growth times predicted from Newtonian theory when standard multipole formulae for the gravitational radiation are used. However, for more compact models, we find that relativistic linear perturbation theory predicts a weakening of the instability compared to the Newtonian results. When turning to polytropic equations of state, we find that for certain ranges of the polytropic index n, the r-mode disappears, and instead of a growth, the time evolutions show a rapid decay of the amplitude. This is clearly at variance with the Newtonian predictions. It is, however, fully consistent with our previous results obtained in the low-frequency approximation.

description: The exploitation of the strong light-matter coupling regime and exciton-polariton condensates has emerged as a compelling approach to introduce strong interactions and nonlinearities into numerous photonic applications, ranging from low-threshold topological lasers to ultrafast all-optical logic devices. The use of colloidal semiconductor quantum dots with strong three-dimensional confinement as the active material in these microcavities would be highly advantageous due to their versatile structural and compositional tunability and wet-chemical processability, as well as potentially enhanced, confinement-induced polaritonic interactions. Yet, to date, cavity exciton-polariton condensation has neither been achieved with epitaxial nor with colloidal quantum dots. Here, we demonstrate room-temperature polariton condensation in a thin film of monodisperse, colloidal CsPbBr$_3$ quantum dots placed in a tunable optical resonator with a Gaussian-shaped deformation serving as wavelength-scale potential well for the polaritons. The onset of polariton condensation under pulsed optical excitation is manifested in emission by its characteristic superlinear intensity dependence, reduced linewidth, blueshift, and extended temporal coherence. Our results, based on this highly engineerable class of perovskite materials with unique optical properties, pave the way for the development of polaritonic devices for ultrabright coherent light sources and photonic information processing.

description: International milk market is created by 7% of world production volume. Volatile world milk prices in recent 6 years caused different forms of its transmission to national levels. In the paper this phenomena is investigated on two levels. First, on macro level how world milk price affects national markets in case of New Zealand as leading world exporter, Germany with growing net export, and Serbia with self-sufficient production. Second, it is analysed vertical price transmission in Serbian milk supply chain, according its magnitude, speed, nature and direction in period January 2007 to May 2013. Results improved understanding how world milk price influence milk price in Serbia and how price shocks are transmitted through milk supply chain for several most important kinds of milk products.Applied vector error correction model in horizontal milk price transmission indicates asymmetry in price transmission from world to Serbian milk market. Milk prices in Serbia respond to price signals from German and world market, but with significant time lags and increasing magnitude over time. From first to fourth month delay, milk prices from German market positively influence Serbian market, and from fifth to tenth month further increasing influence of world milk prices are presented. Nature of spatial asymmetry is positive. Results of threshold vector error correction model applied on dairy supply chain, suggests similar conclusionsfor all four major dairy products on Serbian market. Retail prices react mostly on raw milk price changes, with constant response to processor’s prices. Price shocks are originate at the processor level and are passed to farmers and to retailers. Blurred relationship between processing and retail sector permits more accurate analysis.

description: Disruptive student behavior is a frequent part of school life, most often shown by male students and related to many negative academic outcomes. In this study, we examined the psychological benefits of engaging in disruptive behavior for low-achieving students from an attributional perspective. In an experimental vignette study of 178 ninth graders from Germany, we tested whether the students’ ratings of a target student who displayed disruptive behavior (instead of unobtrusive behavior) in a vignette would evoke lack-of-effort attributions for academic failure through students’ expectations of teachers’ reprimands. In order to account for the nested data structure (vignettes nested in participants), we applied multilevel analysis while testing for mediation effects. Results showed that the disruptive behavior of a target student triggered lack-of-effort attributions in students instead of lack-of-ability attributions for low academic achievement. This effect was mediated by students’ expectations of teachers’ reprimands. In addition, low-achieving students showing disruptive behavior were perceived as more popular but less liked personally and as more masculine and less feminine. The study adds to the understanding of disruptive behavior in class as an attempt of poor-performing students to elicit face-saving attributions for academic failure and enhance their peer status.

description: Regional Trade Agreements (RTAs) have widely spread in recent years. The World Trade Organisation (WTO) notes that 546 RTAs were notified by January 2013, whereas only 380 were notified by 2007. RTAs have been considered as a stumbling block for the slow progress of the WTO Doha Round, and multilateral liberalisation is said to cause erosion of preferences enjoyed under bilateralism. That is, third country exporters that benefit from multilateral trade liberalization increase their exports, whereas the preferential suppliers in bilateral trade agreements face a decrease of their exports, given the substitutability between export products from different countries. Preference erosion also occurs when countries take up new bilateral trade agreements that can result in “old” trade partner countries losing their preferential treatment. The European Union (EU) has granted preferential market access to a large number of countries and is by far the main trading partner of its neighbouring countries, including Mediterranean partner countries (MED countries). Following the Association Agreements with the EU, there have been efforts of enhanced engagement and co-operation, especially after the Arab spring developments, but negotiations for so called free and comprehensive trade agreements (DCFTAs) are also under way with other partner countries. The objective of this paper is to look into possible preference erosion effects from the perspective of MED countries by depicting recent EU trade agreements as well as multilateral trade liberalisation in a simulation analysis. We apply the MAGNET (Modular Applied General Equilibrium Tool) model that builds upon the GTAP (Global Trade Analysis Project) model in a recursive dynamic general equilibrium framework, with a reference scenario that reflects the economic and population growth paths via most recent projections taken from the literature.

We obtain and study the complete set of equations governing the cosmological dynamics. We find they have the same form as those in Randall-Sundrum scenarios but with time-varying four-dimensional gravitational and cosmological constants. Studying the bulk geometry we show that this variation is produced by bulk curvature terms parameterized by the mass of a black hole. Finally, we show there is a coupling between these curvature terms and matter that can be relevant for early universe cosmology.

3D object detection and tracking in debris flows with cameras and LiDARs

name: Bickel, Valentin Tertius

Publisher: name: ETH Zurich
Year: 2024

description: Debris flows are destructive mixtures of water and sediments. In mountain regions, debris flows are a relevant hazard as they threaten people and infrastructure. They move with rapid to extremely-rapid velocities, and often feature a coarse-grained front followed by a liquefied tail. Recently developed LiDAR sensors allow for long-term monitoring of debris-flow dynamics at high spatial (<2 cm) and temporal (10 Hz) resolution in the field, and provide the necessary high-quality data to improve our fundamental understanding of the complex debris-flow behavior.

Here, we present a framework for object detection in debris flows using deep learning algorithms which are trained on 2D camera images, and the results were then fused with LiDAR data to obtain 3D information. We used the YOLOv5 architecture to train a detector of breaking and diffuse surge waves, woody debris, boulders and rolling boulders. The detected objects were then tracked using the SORT algorithm. By subsequently reprojecting the image detections and tracks on the point clouds, 3D information such as velocity was determined. The detector performs very well on the different surge wave types with mean average precisions exceeding 0.9 in the test dataset. The other object types such as woody debris are more difficult to detect and track but still result in mean average precisions around 0.7. Finally, we show how surge waves interact with other objects of the flow by speeding them up and increasing their potential destructive impact. Continued monitoring and application of this method to more debris-flow events will result in an extensive dataset, which would be nearly impossible to obtain with a human operator only. Ultimately, our work will help to improve our understanding of debris-flow dynamics and reduce the hazard associated with this destructive process.

description: The present study investigates the development (i.e., rise or decline) in African agricultural efficiency level and what drives the efficiency over the years. A total of 379 frontier studies resulting in 534 farm level efficiency estimates were considered using meta-regression analysis (MRA) for the empirical analysis. The results show that mean efficiency estimates from the selected case studies decrease significantly as year of survey in the primary study increases. Apparently, this implies that over the years, negative efficiency change characterized the growth of African agriculture and food production. The effect of other study attributes considered in the MRA show that studies published in Journals, with parametric and primal technology specification produced significantly higher efficiency estimates, while those published in top ranking journals and with Cobb-Douglass and Translog functional forms produced significantly lower efficiency estimates. Other results show that education, followed by experience; extension and credit are the major drivers of agricultural efficiency levels in Africa over the years. Given these findings; we suggest policies that encourage investment in human capital development associated with education and extension should be prioritized to enhance the growth of agriculture and food production in the region.

description: We consider a five-dimensional constant curvature black hole, which is constructed by identifying some points along a Killing vector in a five-dimensional AdS space. The black hole has the topology M_4 times S^1, its exterior is time-dependent and its boundary metric is of the form of a three-dimensional de Sitter space times a circle, which means that the dual conformal field theory resides on a dynamical spacetime. We calculate the quasilocal stress-energy tensor of the gravitational background and then the stress-energy tenor of the dual conformal field theory. It is found that the trace of the tensor does indeed vanish, as expected. Further we find that the constant curvature black hole spacetime is just the "bubble of nothing" resulting from Schwarzschild-AdS black holes when the mass parameter of the latter vanishes.

Although the virulence mechanisms of S. canis are not well-characterized, an M-like protein, SCM, has recently identified been as a potential virulence factor. SCM is a surface-associated protein that binds to host plasminogen and IgGs suggesting its possible importance in host-pathogen interactions. In this study, we developed in vitro and ex vivo blood component models and murine models of S. canis vaginal colonization, systemic infection, and dermal infection to compare the virulence potential of the zoonotic S. canis vaginal isolate G361 and its isogenic SCM-deficient mutant (G361∆scm). We found that while S. canis establishes vaginal colonization and causes invasive disease in vivo, the contribution of the SCM protein to virulence phenotypes in these models is modest. We conclude that SCM is dispensable for invasive disease in murine models and for resistance to human blood components ex vivo, but may contribute to mucosal persistence, highlighting a potential contribution to the recently appreciated genetic diversity of SCM across strains and hosts.

description: In a connected world, confidentiality becomes increasingly critical. To cope with confidentiality on a higher abstraction level of software systems, architectural analyses have been proposed. By explicitly modeling data in the system design, the validity of access control policies can be ensured. However, the required information for such analyses is often too imprecise due to the high degree of uncertainty at design-time which results in incomplete and inaccurate policies. In this paper, we describe three key challenges while facing uncertainty and show how software architects could be supported in enhancing confidentiality throughout software design and evolution.

description: The United States is the leading producer and exporter of corn and soybeans in the world. The United States exports 20% of the world’s corn and 30% of the world’s soybeans every year. In this study, we empirically estimate the export demand of U.S. corn and soybeans to three main destinations, China, Japan, and EU, in the current context of energy and agriculture linkages and production of ethanol from corn. A log-linear equation is used to estimate the export demand estimation of U.S. corn and soybeans. Data for the U.S. and its three main importer markets were gathered for the 1980-2011 period. The results of the logarithmic model estimates showed that china had the most elastic demand. China has the highest income elasticity of 2.5, while the income elasticity for Japan and EU were close to 1. The parameter estimates for price of soybean as a cross price was significant for China and EU, and parameter estimates for price of corn as a cross price was significant only for Japan. The positive sign revealed soybeans and corn to be substitutes in those countries.

description: Over the past few decades, efforts of road traffic management and practice have predominantly focused on maximizing system efficiency and mitigating congestion from a system perspective. This efficiency-driven approach implies the equal treatment of all vehicles, which often overlooks individual user experiences, broader social impacts, and the fact that users are heterogeneous in their urgency and experience different costs when being delayed. Existing strategies to account for the differences in needs of users in traffic management cover dedicated transit lanes, prioritization of emergency vehicles, transit signal prioritization, and economic instruments. Even though they are the major bottleneck for traffic in cities, no dedicated instrument that enables prioritization of individual drivers at intersections. The Priority Pass is a reservation-based, economic controller that expedites entitled vehicles at signalized intersections, without causing arbitrary delays for not-entitled vehicles and without affecting transportation efficiency de trop. The prioritization of vulnerable road users, emergency vehicles, commercial taxi and delivery drivers, or urgent individuals can enhance road safety, and achieve social, environmental, and economic goals. A case study in Manhattan demonstrates the feasibility of individual prioritization (up to 40\% delay decrease), and quantifies the potential of the Priority Pass to gain social welfare benefits for the people. A market for prioritization could generate up to 1 million \$ in daily revenues for Manhattan, and equitably allocate delay reductions to those in need, rather than those with a high income.

description: This study looks at the economic feasibility of Alternate Wet Drying (AWD) irrigation methods to address concerns of groundwater depletion and greenhouse gas (methane) emissions associated with rice production. AWD is an irrigation régime where the producer allows the rice field to dry intermittently during the rice life-cycle rather than having the field continuously submerged. In previous studies AWD has been found to reduce water usage by from 20-70% and to reduce methane emissions by over 50% as compared to rice produced under continuous flooding. However; the large disadvantage of AWD is that it is often times associated with a yield loss. Thus, this study sets out to estimate the economic viability of three types of AWD irrigation methods in Arkansas using test plot data. Data includes water usage, methane emissions and yields for three hybrid rice varieties across three years and three AWD methods. The goals of this study are to (1) estimate if any of the AWD methods demonstrate higher profitability than traditional flooding (2) introduce a carbon offset market to capture benefits of the GHG reduction, via methane, and estimate profitability between AWD and traditional flooding (3) introduce a water tax equivalent to the social cost of water and reestimate profitability of AWD and traditional flooding. These results will give producers as well as large rice buyers (MARS and Kelloggs) an idea of relative profitability and additional premiums necessary to switch to/source a more “sustainable” rice crop.

description: Reflections about the historical roots of our current scientific endeavors are useful from time to time as they help us to acknowledge the ideas, concepts, methodological approaches, and idiosyncrasies of the researchers that paved the ground we stand on right now. The 50-year anniversary of Apidologie offers the opportunity to refresh our knowledge about the history of bee research. I take the liberty of putting the founding year of Apidologie in the middle of the period I cover here. The nascent period of behavioral biology around the late 19th to the early twentieth century was intimately connected with a loss of concepts related to the mental functions of the brain, concepts that were rooted in Darwin’s theory of gradualism in the living world including cognition in animals. This loss was celebrated both in ethology and behaviorism as the gateway to scientific impartiality. Using this apparently strict scientific approach, impressive discoveries were made by observing and strictly quantifying the behavior of bees. The first forays into the brain, however, uncovered a richness of structure and function that reached far beyond stereotypical input/output connections and opened the way to compensating the conceptual restrictions imposed on us by traditional ethology. Honeybee research provides us with a particularly exciting story in this context. The cognitive turn in behavioral biology is intimately connected to the increasing knowledge of how the brain works, also in honeybee research. What has been achieved so far is just the beginning, but it gives us a glimpse of a promising future. Teamwork between neuroscientists and behavioral biologists is needed to elucidate brain functions such as the expectation of future outcomes and intentionality as an entry to animal intelligence reflecting the flexibility and adaptability in behavior also seen in honeybees.

description: We give an action of the symmetric group on non-commuting indeterminates in terms of series in the corresponding Mal'cev-Newmann division ring. The action is constructed from the non-Abelian Hirota-Miwa (discrete KP) system. The corresponding companion map, which gives generators of the action, is discussed in the generic case and the corresponding explicit formulas have been found in the periodic reduction. We discuss also briefly connection of the companion to the KP map with context-free languages.
