description: As we enter an era of increasing water scarcity, there is a growing interest to find ways to capture and put water to more productive uses. Substantial increases in the productivity of water in agriculture are needed to meet the demands for food and ensure environmental security, and to satisfy the demands for non-agricultural uses. However, increasing water productivity in rice-dominated agriculture is a function of the irrigation infrastructure, advances in rice-plant breeding, and the physical, institutional and socioeconomic environments. This paper first describes the potential ways in which increased water productivity can be achieved in the context of rice production in Asia. It then illustrates the ways in which the differences in the environmental context affect the ability to increase water productivity, the approaches used and the incentives to do so. This is explained using two ‘case studies’ reflecting the experiences of Taiwan and the Philippines over the past half-century.

description: In Ref. 3, we presented an asymptotic formula for the fermion-induced effective energy in 3+1 dimensions in the presence of a cylindrically symmetric inhomogeneous strong magnetic field. However, there are some points which were not clearly explained. In fact, the arguments, which led us to the asymptotic formula, are based on a numerical study of the integral of Eq. (10), as we will see in the main part of this paper. The aim of this work is to present this study in detail.

description: In this paper, we present results from a human-subject study designed to explore two facets of human mental models of robots---inferred capability and intention---and their relationship to overall trust and eventual decisions. In particular, we examine delegation situations characterized by uncertainty, and explore how inferred capability and intention are applied across different tasks. We develop an online survey where human participants decide whether to delegate control to a simulated UAV agent. Our study shows that human estimations of robot capability and intent correlate strongly with overall self-reported trust. However, overall trust is not independently sufficient to determine whether a human will decide to trust (delegate) a given task to a robot. Instead, our study reveals that estimations of robot intention, capability, and overall trust are integrated when deciding to delegate. From a broader perspective, these results suggest that calibrating overall trust alone is insufficient; to make correct decisions, humans need (and use) multi-faceted mental models when collaborating with robots across multiple contexts.

description: This paper examines present and future demand for water in the Zayandeh Rud basin, and determines the extent to which water will be available for agricultural use by the year 2020. Current demand and supply were more or less in balance in 2000 but by 2010 there will be an increase in supply of some 28% due to the completion of a third transbasin diversion and development of other local water sources. If growth in all sectors is assumed to be 2% p.a. then demand will exceed supply by 2010 and the basin will go into severe deficit by 2020. The same is true if demand only grows at 1% a year. As it is unlikely that urban, industrial and environmental demands will decrease, the only way to keep supply and demand in balance is to reduce allocations to agriculture. By 2020 agriculture will only have 5% more water than at present despite the transbasin diversions, and will shrink from 2025 onwards. However, in years when water supply is only 90% of normal then agriculture will have to shrink in order to keep other sectors supplied.
The High Energy Behavior of Mellin Amplitudes

description: In any consistent massive quantum field theory there are well known bounds on scattering amplitudes at high energies. In conformal field theory there is no scattering amplitude, but the Mellin amplitude is a well defined object analogous to the scattering amplitude. We prove bounds at high energies on Mellin amplitudes in conformal field theories, valid under certain technical assumptions. Such bounds are derived by demanding the absence of spurious singularities in position space correlators. We also conjecture a stronger bound, based on evidence from several explicit examples.

description: As a complementary or companion process to the Blandford-Znajek mechanism for the rotational energy extraction from a Kerr black hole to serve as a viable model for the central engine of quasar, AGN and even GRB, the magnetic alignment process is proposed. In contrast to the environment assumed in the Blandford-Znajek mechanism in which the rotating hole's spin axis and the asymptotic direction of the magnetic field are aligned, this new process operates when they are generally misaligned which obviously is the more natural situation likely to happen. The time scales over which these two processes take place and the total radiated powers released at the horizon by them have been estimated and found to be nearly comparable. This may imply that in a random, non-axisymmetric configuration, the magnetic alignment process would operate first during which some of the hole's rotational energy is released and upon completion of the alignment, the Blandford-Znajek mechanism may follow and the rest of the hole's rotational energy, if any left, would be further released.

description: Increasing female and male farmers’ access to groundwater can contribute to increased incomes, improved food security and improved access to water for livestock and domestic needs. In many contexts, private sector manual well drilling is a reliable and affordable means to access shallow groundwater, but it is not widely available in Ethiopia. Data, information and mapping on pilot manual well drilling efforts in selected areas of Ethiopia indicated that the technique provided affordable access to shallow groundwater for farmers and demonstrated high demand among farmers for manually drilled wells, as well as profitability for drilling businesses. The authors of this paper suggest that investments in creating a spatial database of hydrogeologic suitability domains, investments in driller training, and associated investments in accelerating the drilling industry could catalyze a manual well drilling industry and significantly improve smallholder farmers’ affordable access to shallow groundwater.
Effects of the Great American Solar Eclipse on the lower ionosphere observed with VLF waves

description: The altitude of the ionospheric lower layer (D-region) is highly influenced by the solar UV flux affecting in turn, the propagation of Very Low Frequency (VLF) signals inside the waveguide formed between this layer and the Earth surface. A rapid change of the solar irradiance, as during a solar eclipse, can help to understand the details of the energy transfer of the solar radiation onto the ionospheric D-layer. Using the "Latin American VLF Network" (LAVNet-Mex) receiver station in Mexico City, Mexico, we detected the phase and amplitude changes of the VLF signals transmitted by the NDK station at 25.2 kHz in North Dakota, USA during the August 21, 2017, solar eclipse. As the Sunlight was eclipsed, the rate of ionization in the ionosphere (D-region) was reduced and the effective reflection height increased, causing a considerable drop of the phase and amplitude of the observed VLF waves. The corresponding waveguide path is 3007.15 km long and crossed almost perpendicularly the total eclipse path. Circumstantially, at the time of the total eclipse, a C3 flare took place allowing us to isolate the flare flux from the background flux of a large portion of the disk. In this work, we report the observations and present a new model of the ionospheric effects of the eclipse and flare. The model is based on a detailed setup of the degree of Moon shadow that affects the entire Great Circle Path (GCP). During the eclipse, the maximum phase variation was -63.36$^{\circ}$ at 18:05 UT which, according to our model, accounts for a maximum increase of the reflection height of 9.3 km.

description: We combined deep Chandra, ROSAT HRI, and XMM-Newton observations of M87 to study the impact of AGN outbursts on its gaseous atmosphere. Many X-ray features appear to be a direct result of repetitive AGN outbursts. In particular, the X-ray cavities around the jet and counter jet are likely due to the expansion of radio plasma, while rings of enhanced emission at 14 and 17 kpc are probably shock fronts associated with outbursts that began 1-2\times10^7 years ago. The effects of these shocks are also seen in brightenings within the prominent X-ray arms. On larger scales, ~50 kpc from the nucleus, depressions in the surface brightness may be remnants of earlier outbursts. As suggested for the Perseus cluster (Fabian et al.), our analysis of the energetics of the M87 outbursts argues that shocks may be the most significant channel for AGN energy input into the cooling flow atmospheres of galaxies, groups, and clusters. For M87, the mean power driving the shock outburst, 2.4\times 10^{43} ergs/sec, is three times greater than the radiative losses from the entire ``cooling flow''. Thus, even in the absence of other energy inputs, outbursts every 3\times10^7 years are sufficient to quench the flow.

Overflowing and underfuelled - The state of municipal solid waste management in Blantyre, Malawi
Creators: name: Seemann-Ricard, Nicolas
Publisher: name: ETH Zurich
Year: 2024

description: This brief presents the findings from a field study carried out in Blantyre, Malawi between September and November 2023. The research focused on the operation of the Blantyre City Council’s (BCC) waste collection service, the generation of waste at community collection points (skips), and how collection service could be improved.
The tracking of collection vehicles and monitoring of skips reveal a mismatch between the number of trucks in operation and service quality. As the collection vehicles are not used to their full potential, many skips are left overflowing for several days at a time. Indeed, at any one time, more than half of skips are overflowing.
Currently, the BCC is facing two main problems: the lack of effective operational funding, and the lack of operational planning. The very restricted fuel allowance severely limits BCC’s Cleansing Section from effectively collecting and disposing of waste. At the same time, the Cleansing Section, itself part of the Health and Social Services department, lacks the flexibility and information to make day-to-day decisions such as fuel allocations for different vehicles and scheduling.
As the city of Blantyre expands its operations and the amount of infrastructure under its management, these problems will only be exacerbated. Without an increased fuel budget, the addition of more vehicles will simply result in less fuel for each truck. Similarly, without a comprehensive data and monitoring strategy, BCC will struggle to adequately service any new collection points or introduce data-driven plans that can optimize the servicing of their expanding infrastructure portfolio.

description: Many possible scenarios for the formation of multiple stellar populations (MSP) in globular clusters (GCs) have been discussed so far, including the involvement of asymptotic giant branch stars, fast rotating main sequence stars, very massive main sequence stars and mass-transferring massive binaries based on stellar evolution modelling. But self-consistent, dynamical simulations of very young GCs are usually not considered. In this work, we perform direct $N$-body modelling such systems with total masses up to $3.2\times10^5$ M$_\odot$, taking into account the observationally constrained primordial binary properties, and discuss the stellar-mergers driven both by binary stellar evolution and dynamical evolution of GCs. The occurrence of stellar mergers is enhanced significantly in binary-rich clusters such that stars forming from the gas polluted by mergers-driven ejection/winds would appears as MSPs. We thus emphasize that stellar mergers can be an important process that connects MSP formation with star cluster dynamics, and that multiple MSP formation channels can naturally work together. The scenario studied here, also in view of a possible top-heavy IMF, may be particularly relevant for explaining the high mass fraction of MSPs (the mass budget problem) and the absence of MSPs in young and low-mass star clusters.

description: During the past decade, smallholder groundwater irrigation with motor pumps has increased considerably in Zambia. The present study analyzes an important, but hitherto ignored, factor for adoption: the supply chain of imported motor pumps. Findings include types of pumps; organization of import, wholesale and retail, including after-sales services; fiscal measures (import duty waiver and VAT zero rating); prices of pumps; and financing facilities to the farmers. The main obstacles for farmers were found to be: the highly centralized supply chain and financing facilities in urban hubs; lack of information, also about prices, which vary significantly even for the same make and model of pump; lack of information and training about proper use and maintenance; and lack of financing facilities. The Zambia National Farmers Union seems best placed to remove these obstacles.

description: The additional data necessary to univocally fix the gauge group for a given algebra are represented by the same charge lattices of mutually local Wilson and 't Hooft lines for both 4d $\mathcal{N}=4$ SYM and $\mathcal{N}=2$ elliptic models. Motivated by this equivalence in this paper we study the Lens space index of these $\mathcal{N}=2$ elliptic models. The index is indeed sensitive to the global properties and in the $\mathcal{N}=4$ case it is expected to coincide among S-dual models with different global properties, while it gives different results for models that lie in other S-duality orbits. Here by an explicit calculation we show that the same results hold for the $\mathcal{N}=2$ elliptic models as well.

description: We propose the second moment of the Husimi distribution as a measure of complexity of quantum states. The inverse of this quantity represents the effective volume in phase space occupied by the Husimi distribution, and has a good correspondence with chaoticity of classical system. Its properties are similar to the classical entropy proposed by Wehrl, but it is much easier to calculate numerically. We calculate this quantity in the quartic oscillator model, and show that it works well as a measure of chaoticity of quantum states.

description: We study the stability properties of static, spherically symmetric configurations in k-essence theories with the Lagrangians of the form $F(X)$, $X \equiv ϕ_{,α} ϕ^{,α}$. The instability under spherically symmetric perturbations is proved for two recently obtained exact solutions for $F(X) =F_0 X^{1/3}$ and for $F(X) = F_0 X^{1/2} - 2 Λ$, where $F_0$ and $Λ$ are constants. The first solution describes a black hole in an asymptotically singular space-time, the second one contains two horizons of infinite area connected by a wormhole. It is argued that spherically symmetric k-essence configurations with $n < 1/2$ are generically unstable because the perturbation equation is not of hyperbolic type.

description: This Working Paper presents methodological and substantive findings of gender-differentiated quantitative farm household surveys about smallholders’ private irrigation technology adoption in Ghana and Zambia. Focusing on three gender variables, household headship, labor provision and plot management, the paper examines adoption rates, types of technologies and gendered labor provision in female- and male-headed households; compares adoption rates on women’s own plots with overall rates; compares women’s decision-making on irrigated plots and rainfed plots; and examines impacts of targeting strategies. Findings suggest that women are proactive irrigation adopters in spite of the many obstacles they face. Removing those obstacles serves both gender equality and irrigation policies.
Can Android Smartphones Contribute to GNSS Meteorology?

description: The Global Navigation Satellite System (GNSS) is an essential tool for tropospheric monitoring. Currently, GNSS meteorology relies mainly on the data collected from geodetic-grade receivers of global or regional networks. However, such stations are costly, and thus cannot be densely deployed, especially in less developed regions. Since the release of the Android 7 operating system in 2016, Android smartphones can be used to collect raw GNSS data. Considering that nowadays there are about 3 billion Android smartphones worldwide, it is intriguing to study the potential of using such devices for GNSS meteorology applications. In this contribution, we demonstrate zenith total delay (ZTD) estimation with Android smartphone GNSS data. Firstly, a dedicated data processing pipeline was implemented, including ionospheric delay interpolation and Precise Point Positioning (PPP)-based ZTD estimation with factor graph optimization. A set of 24-hour smartphone GNSS data were collected on the rooftop of the ETH campus. The ZTDs derived from ERA5 products and a nearby geodetic-grade receiver served as benchmarks. The results reveal that an accuracy of better than 10 mm can be achieved by utilizing smartphone GNSS data collected in open-sky environments. Furthermore, limiting factors, such as the data collection environment, minimal time span, and missing information of antenna phase center variation, are also discussed. The results of this study reveal success factors and current limitations of Android smartphones for GNSS meteorology.

description: We present a novel framework to self-consistently model the effects of radiation fields, dust physics and molecular chemistry (H$_2$) in the interstellar medium (ISM) of galaxies. The model combines a state-of-the-art radiation hydrodynamics module with a non-equilibrium thermochemistry module that accounts for H$_2$ coupled to a realistic dust formation and destruction model, all integrated into the new stellar feedback framework SMUGGLE. We test this model on high-resolution isolated Milky-Way (MW) simulations. We show that photoheating from young stars makes stellar feedback more efficient, but this effect is quite modest in low gas surface density galaxies like the MW. The multi-phase structure of the ISM, however, is highly dependent on the strength of the interstellar radiation field. We are also able to predict the distribution of H$_2$, that allow us to match the molecular Kennicutt-Schmidt (KS) relation, without calibrating for it. We show that the dust distribution is a complex function of density, temperature and ionization state of the gas which cannot be reproduced by simple scaling relations often used in the literature. Our model is only able to match the observed dust temperature distribution if radiation from the old stellar population is considered, implying that these stars have a non-negligible contribution to dust heating in the ISM. Our state-of-the-art model is well-suited for performing next generation cosmological galaxy formation simulations, which will be able to predict a wide range of resolved ($\sim 10$ pc) properties of galaxies.

description: Setelah perang dunia I dan setelah depresi ekonomi dunia pada tahun 1930-an, dunia menginginkan tercapainya suatu stabilitas ekonomi yang lebih baik. Pada tahun 1944 lahirlah suatu sistem moneter Internasional yang dikenal dengan nilai tukar tetap (fixed exchange rate) hasil persetuuan Bretton woods. Setiap Negara memberlakukan kurs yang tetap dari mata uangnya terhadap US. Sejak saat itu ekonomi negara-negara Eropa serta Amerika mulai tumbuh pesat. Lebih dari itu lahirnya pasar Euro Dolar dan Asia Currency Unit adalah untuk mengimbangi peredaran US Dollar yang semakin banyak jumlahnya. Pentingnya aktivitas dalam foreign exchange timbul sehubungan dengan berkembangnya perdagangan internasional serta semakin meningkatnya perpindahan uang dan capital internasional. Dari sini bisa dilihat bahwa foreign exchange bukan sebatas money change tetapi lebih luas dari itu. Oleh karena itu, dapat dikatakan bahwa pasar valuta asing adalah suatu pasar di mana surat-surat berharga jangka pendek diperdagangkan.

description: Brane world cosmologies seem to provide an alternative explanation for the present accelerated stage of the Universe with no need to invoke either a cosmological constant or an exotic \emph{quintessence} component. In this paper we investigate statistical properties of gravitational lenses for some particular scenarios based on this large scale modification of gravity. We show that a large class of such models are compatible with the current lensing data for values of the matter density parameter $Ω_{\rm{m}} \leq 0.94$ ($1σ$). If one fixes $Ω_{\rm{m}}$ to be $\simeq 0.3$, as suggested by most of the dynamical estimates of the quantity of matter in the Universe, the predicted number of lensed quasars requires a slightly open universe with a crossover distance between the 4 and 5-dimensional gravities of the order of $1.76 H_o^{-1}$.

cloudbandPy 1.0: an automated algorithm for the detection of tropical-extratropical cloud bands
Creators: name: Pilon, Romain

Publisher: name: ETH Zurich
Year: 2023

description: Persistent and organized convective cloud systems that arise in convergence zones can lead to the formation of synoptic cloud bands extending from the tropics to the extratropics. These cloud bands are responsible for heavy precipitation and are often a combination of tropical intrusions of extratropical Rossby waves and of processes originating from the tropics. Detecting these cloud bands presents a valuable opportunity to enhance our understanding of the variability of these systems and the underlying processes that govern their behavior and that connect the tropics and the extratropics. This paper presents a new atmospheric cloud band detection method based on outgoing longwave radiation using computer vision techniques, which offers enhanced capabilities to identify long cloud bands across diverse gridded datasets and variables. The method is specifically designed to detect extended tropical-extratropical convective cloud bands, ensuring accurate identification and analysis of these dynamic atmospheric features in convergence zones. The code allows for easy configuration and adaptation of the algorithm to meet specific research needs. The method handles cloud band merging and splitting, which allows for an understanding of the life cycle of cloud bands and their climatology. This algorithm lays the groundwork for improving our understanding of the large-scale processes that are involved in the formation and life cycle of cloud bands and the connections between tropical and extratropical regions, and to evaluate the differences in cloud band types between different ocean basins.

description: Conformation of a protein (CorA) is examined in a matrix with mobile solute constituents as a function of solute-residue interaction strength (f) by a coarse-grained model with a Monte Carlo simulation. Solute particles are found to reach their targeted residue due to their unique interactions with the residues. Degree of slowing down of the protein depends on the interaction strength f. Unlike a predictable dependence of the radius of gyration of the same protein on interaction in an effective medium, it does not show a systematic dependence on interaction due to pinning caused by the solute binding. Spread of the protein chain is quantified by estimating its effective dimension (D) from scaling of the structure factor. Even with a lower solute-residue interaction, the protein chain appears to conform to a random-coil conformation (D ~ 2) in its native phase where it is globular in absence of such solute environment. The structural spread at small length scale differs from that at large scale in presence of stronger interactions: D ~ 2.3 at smaller length scale and D ~ 1.4 on larger scale with f = 3.5 while D ~ 1.4 at smaller length scale and D ~ 2.5 at larger length scales with f = 4.0.

description: High-resolution Doppler spectroscopy has been used to detect several chemical species in exoplanetary atmospheres. Such detections have traditionally relied on cross correlation of observed spectra against spectral model templates, an approach that is successful for detecting chemical species but not optimised for constraining abundances. Recent work has explored ways to perform atmospheric retrievals on high-resolution spectra (HRS) and combine them with retrievals routinely performed for low-resolution spectra (LRS) by developing a mapping from the cross correlation function to a likelihood metric. We build upon previous studies and report HyDRA-H, a hybrid retrieval code for simultaneous analysis of low- and high- resolution thermal emission spectra of exoplanets in a fully Bayesian approach. We demonstrate HyDRA-H on the hot Jupiter HD 209458b as a case study. We validate our HRS retrieval capability by confirming previous results and report a simultaneous hybrid retrieval using both HRS and LRS data. The LRS data span the HST WFC3 (1.1-1.7 $μ$m) and Spitzer photometry (IRAC 3.6-8 $μ$m) bands, while the HRS data were obtained with CRIRES on VLT at 2.3 $μ$m. The constraints on the composition and temperature profiles for the hybrid retrieval are more stringent than retrievals with either LRS or HRS datasets individually. We retrieve abundances of $\log(\mathrm{H_2O)} = -4.11^{+0.91}_{-0.30}$ and $\log(\mathrm{CO}) = {-2.16}^{+0.99}_{-0.47}$, and $\mathrm{C/O} = 0.99^{+0.01}_{-0.02}$, consistent with previous works. We constrain the photospheric temperature to be $1498^{+216}_{-57}$ K, consistent with the equilibrium temperature. Our results demonstrate the significant advantages of hybrid retrievals by combining strengths of both HRS and LRS observations which probe complementary aspects of exoplanetary atmospheres.
