description: This paper examines the performance of contract farming when agents are groups of jointly-liable farmers who receive input credit from a monopsonistic agribusiness. Accounting for group mechanisms in credit repayment through joint liability and peer monitoring, we derive the optimal monopsonistic contract under moral hazard on production effort. The principal takes into account price incentives not only on farmers’ effort but also on peer monitoring. Then, we show that the optimal pricing rule is not monotonic with respect to the group’s characteristics. Imperfect information implies a distortion on pricing for low-efficient groups, which is Pareto-improving from a social point. Groups of intermediary size and heterogeneity provide the best effort and peer-monitoring incentives.

Storytelling deviations and attention disputes in Brazilian Netflix originals

Year: 2021

description: In this article, we seek to highlight and discuss some changes observed in Brazilian Netflix series since 2016 that play an important role in the complexity of the productions. Those changes are expansions in the classical narrative and plot model, with consequent changes in the strategies of information distribution, the effect on how viewer attention is gained and the thematic development of the productions. Regarding the methodology, we adopted a poetic reading based on David Bordwell’s considerations on the classical storytelling model. And we explore the following aspects in the Netflix original series Boca a Boca (2020): the expansion of anticipation of the inciting incident in the narrative structure; the change of the main line of action based on the Multiplot design in the plot structure; and we also analyze the staging solutions that stand out. We concluded that the expansions contributed to a greater demand for viewer attention, in addition to encouraging a diversity of points of view and greater complexity of the theme. The series seems to advance in a more technical way in its articulation of the reference world and the dramatic dimensions, making dramatic motifs preponderate over dramatic themes.

description: In this paper, we extend the bilinear generalized approximate message passing (BiG-AMP) approach, originally proposed for high-dimensional generalized bilinear regression, to the multi-layer case for the handling of cascaded problem such as matrix-factorization problem arising in relay communication among others. Assuming statistically independent matrix entries with known priors, the new algorithm called ML-BiGAMP could approximate the general sum-product loopy belief propagation (LBP) in the high-dimensional limit enjoying a substantial reduction in computational complexity. We demonstrate that, in large system limit, the asymptotic MSE performance of ML-BiGAMP could be fully characterized via a set of simple one-dimensional equations termed state evolution (SE). We establish that the asymptotic MSE predicted by ML-BiGAMP' SE matches perfectly the exact MMSE predicted by the replica method, which is well known to be Bayes-optimal but infeasible in practice. This consistency indicates that the ML-BiGAMP may still retain the same Bayes-optimal performance as the MMSE estimator in high-dimensional applications, although ML-BiGAMP's computational burden is far lower. As an illustrative example of the general ML-BiGAMP, we provide a detector design that could estimate the channel fading and the data symbols jointly with high precision for the two-hop amplify-and-forward relay communication systems.

description: The development of synthetic strategies to engineer π-conjugated polymers is of paramount importance in modern chemistry and materials science. Here we introduce a theoretical and experimental synthetic paradigm based on the search for specific vibrational modes through an appropriate tailoring of the π-conjugation of the precursors, in order to increase the attempt frequency of a chemical reaction. First, we on-surface design a 1D π-conjugated polymer with specific π-topology, which is based on bisanthene monomers linked by cumulene bridges that tune specific vibrational modes. In a second step, upon further annealing, such vibrational modes steer the two-fold cyclization reaction between adjacent bisanthene moieties, which gives rise to a long and free-defect pentalene-bridged conjugated ladder polymer featuring a low band gap. In addition, high resolution atomic force microscopy allows us to identify by atomistic insights the resonant form of the polymer, thus confirming the validity of the Glidewell and Lloyd's rules for aromaticity. This on-surface synthetic strategy may stimulate exploiting previously precluded reactions towards novel pi-conjugated polymers with specific structures and properties.

description: Nanometer-sized columns of condensed water molecules are created by an atomic-resolution force microscope operated in ambient conditions. Unusual stepwise decrease of the force gradient associated with the thin water bridge in the tip-substrate gap is observed during its stretch, exhibiting regularity in step heights (~0.5 N/m) and plateau lengths (~1 nm). Such "quantized" elasticity is indicative of the atomic-scale stick-slip at the tip-water interface. A thermodynamic-instability-induced rupture of the water meniscus (5-nm long and 2.6-nm wide) is also found. This work opens a high-resolution study of the structure and the interface dynamics of a nanometric aqueous column.

description: Unintended consequences of announcing a climate policy well in advance of its implementation have been studied in a variety of situations. We show that a phenomenon akin to the so-called “Green- Paradox” holds also when the policy implementation date is uncertain. Governments are compelled, by international and domestic pressure, to demonstrate an intention to reduce greenhouse gas emissions. Taking actual steps, such as imposing a carbon tax on fossil energy, is a different matter altogether and depends on a host of political considerations. As a result, economic agents often consider the policy implementation date to be uncertain. We show that in the interim period between the policy announcement and its actual implementation the emission of green-house gases increases vis-`a-vis business-as-usual.
Identification of bacterial factors associated with the survival of Burkholderia cenocepacia in a murine host
Creators: name: Chung, Jacqueline W.
Publisher: name: University of British Columbia
Year: 2009

description: The Burkholderia cepacia complex (BCC) is a family of Gram-negative bacteria of evolving importance as opportunistic pathogens, particularly in patients with cystic fibrosis (CF). BCC infections are difficult to treat and control due to the BCC's intrinsic resistance to antibiotics and ability to spread among patients. Moreover BCC colonization can develop into septicemia. Although recognized as a serious respiratory pathogen, little is known about the pathogenesis of the BCC. The purpose of these studies was to identify bacterial factors involved in BCC infection and colonization using animal models that show differential persistence and virulence among BCC strains in a murine host. Serial mouse passage of non-persistent BCC strain C1394 in a pulmonary infection model resulted in its adaptation to the murine host and produced a variant, C1394mp2 that persisted in the murine lung. The parent strain and variant were indistinguishable by genetic typing, but differed in colonial morphology and were compared to identify the bacterial determinants required for long-term infection in a murine host. The parent strain, C1394 had a matte colonial phenotype, made scant exopolysaccharide (EPS), and was lightly piliated. The variant, C1394mp2 had a shiny colonial phenotype, produced abundant EPS, and was heavily piliated. Matte to shiny colonial transformation was induced by growth at 42°C. Proteomic analysis of C1394 and C1394mp2 protein profiles at 37°C revealed increased flagellin production in C1394mp2 whereas C1394 had increased production of metabolizing enzymes of the tricarboxylic acid cycle. Differential expression of the stress-induced protein peroxiredoxin was observed in the proteomes of C1394 and C1394mp2 at 37°C and 42°C respectively. Further comparisons included in vitro assays examining host cell interactions with C1394 and C1394mp2. Though both isolates had poor nonopsonic association with primary human phagocytic cells, C1394mp2 had even less association than C1394. Binding assays with A549 epithelial cells also revealed lower association with C1394mp2 than C1394. The results in this thesis identified BCC surface determinants that were associated with a colonial morphology change, which could be induced under stress, and correlated with long-term infection in a murine host and decreased association with human host cells. Taken together, these results suggest putative bacterial factors that are necessary for BCC survival and chronic infections susceptible hosts.

description: Inequality decomposition techniques are used to analyze the different impacts of domestic and international remittances on household income inequality in the Dominican Republic. Domestic remittances seem more likely to be equalizing than international remittances. The negative marginal effect on inequality of domestic remittances is more prominent among rural households, and in particular among landless rural households, while the negative marginal effect on inequality of international remittances is more prominent among urban households, and in particular outside of the Santo Domingo area. Stronger marginal effects of remittances were found among female-headed households, the elderly and the less educated. Both domestic and international remittances are higher among female-headed households and the elderly. Education is associated with lower domestic remittances and higher international remittances, probably reflecting the role of education in promoting international versus domestic migration. An increase in schooling increases inequality through domestic remittances and decreases inequality through international remittances, while a reduction in household size reduces inequality through both domestic and international remittances. This analysis highlights the importance of the distinction between domestic and international remittances as drivers of inequality as well as the importance of identifying and quantifying the determinants of remittances and their subsequent impact on inequality.

description: This paper analyzes the effect of competition on product demonstration decisions. Pre-purchase product demonstration enables marketers to differentiate products that are ex-post differentiated but are judged according to perceived fit, rather than actual fit, due to pre-purchase consumer uncertainty. Imbalanced competition accompanied by fit uncertainty motivates the follower to offer demonstrations to avoid a price war. This paper explores the conditions that lead the leader to retaliate. In addition to effects on quantity, competition may increase the quality of demonstrations offered by the leader. We analyze a business case, showing that competition may increase the demonstration intensity and that the leading manufacturer’s response to changes in competition is stronger than the responses of the followers. Our research has the potential to aid mangers in formulating demonstration strategies and in responding to competitors’ demonstration efforts.
The Role of Groundwater Depletion in Local and Global Climate Change
Creators: name: Jomaa, Ihab
Publisher: name: Zenodo
Year: 2025

description: Abstract

Groundwater depletion is emerging as one of the most pressing environmental and socio-economic issues of the 21st century, driven by rapid population growth and increasing demand for freshwater. Groundwater supplies about 30% of the world's freshwater, but in many regions, it is being extracted faster than it can naturally replenish. This overuse is leading to severe consequences for ecosystems, agriculture, and communities, with wells drying up, agricultural productivity threatened, and freshwater supplies becoming increasingly unreliable. Additionally, the depletion of groundwater exacerbates climate change, contributing to local temperature increases and altered precipitation patterns. While much attention is given to the role of greenhouse gas emissions in global warming, groundwater depletion is also a significant, yet underexplored, driver of climate change. As groundwater levels fall, heat trapped in the soil increases, further warming the surface and disrupting climate systems. This feedback loop amplifies local climate effects, intensifying droughts, heatwaves, and erratic weather patterns. Moreover, groundwater depletion impacts the accuracy of climate data from weather stations, as urbanization and changes in land cover affect temperature readings. This research highlights the need for a more integrated approach that includes sustainable groundwater management, accurate climate monitoring, and a broader understanding of the complex relationship between water resources and climate. Groundwater depletion is not only a water crisis but also a climate crisis that demands immediate and comprehensive attention.

description: We show that in the D1-D5 system with angular momentum, there can be localised tachyonic winding string modes in the interior of the spacetime even if we choose a spin structure which preserves supersymmetry in the asymptotic region. We consider cases where the tachyonic region extends outside the event horizon, and argue that the natural endstate of tachyon condensation in almost all cases is one of the solitonic solutions which correspond to special microstates of the D1-D5 system.

description: Reducing energy demand by 50% by 2050 is one of the two core components of the City of Frankfurt’s “Master Plan 100% Climate Protection”. According to this ambitious Master Plan, Frankfurt aims to reduce its current energy demand by half and to cover the remaining half through renewable energy. Since households account for 22% of Frankfurt’s current energy demand, the achievement of the energy efficiency target largely hinges on private homeowners’ ability to retrofit their buildings. However, homeowners’ ability to retrofit their buildings for energy efficiency has so far been hampered by the high cost of retrofitting and lack of adequate financial resources. Despite the presence of some financial schemes designed to address this problem (at the national level), Frankfurt does not have adequate and coordinated retrofit-financing scheme tailored to its specific situation. We consider this to be a serious problem and major stumbling block in Frankfurt’s effort to become energy efficient and thereby attain its 100% renewable energy vision. Against this backdrop, we came up with a solution that is capable of overcoming the financial barriers preventing private homeowners in the City of Frankfurt from retrofitting their buildings for energy efficiency. Our financial solution is designed in such a way that homeowners virtually pay noting to get their building retrofitted. The scheme will enable homeowners to get a government subsidy plus long term, low interest rate retroFrank loans, which will be paid back through energy saving over time.

description: In this study, we performed comprehensive morphological investigations of the spontaneous formations of effective network structures among elements in coupled logistic maps, specifically with a delayed connection change. Our proposed model showed ten states with different structural and dynamic features of the network topologies. Based on the parameter values, various stable networks, such as hierarchal networks with pacemakers or multiple layers, and a loop-shaped network were found. We also found various dynamic networks with temporal changes in the connections, which involved hidden network structures. Furthermore, we found that the shapes of the formed network structures were highly correlated to the dynamic features of the constituent elements. The present results provide diverse insights into the dynamics of neural networks and various other biological and social networks.

description: The advent of the Internet changed the way buyers and sellers interact. Although access to information seems unlimited, non-expert agents find it difficult to identify the information they can confidently use. A third-party expert or a cybermediary (an intermediary in the cyberspace) can help sort out the information for the contracting partners. In this paper, we study the case of the online hotel market and the role of the cyber travel agent (CTA). We claim that CTAs encourage hoteliers to exert effort in service quality and provide empirical evidence that these hotels are compensated with a price premium.

description: We consider a semiclassical approximation for the time evolution of an originally gaussian wave packet in terms of complex trajectories. We also derive additional approximations replacing the complex trajectories by real ones. These yield three different semiclassical formulae involving different real trajectories. One of these formulae is Heller's thawed gaussian approximation. The other approximations are non-gaussian and may involve several trajectories determined by mixed initial-final conditions. These different formulae are tested for the cases of scattering by a hard wall, scattering by an attractive gaussian potential, and bound motion in a quartic oscillator. The formula with complex trajectories gives good results in all cases. The non-gaussian approximations with real trajectories work well in some cases, whereas the thawed gaussian works only in very simple situations.

description: To investigate the immunotherapeutic effects of macrophage-like induced pluripotent stem (iPS) cell-derived suppressor cells (SCs) in ocular immune response and experimental autoimmune uveoretinitis (EAU). The genes of Oct3/4, Sox2, Klf4, and c-Myc were transferred to B cells enriched from the spleen cells of C57BL/6 mice by using retrovirus vectors. Transferred B cells were cultured for 17 days to obtain colonies of iPS cells. Through additional steps, iPS-SCs were induced. An antigen-specific T cell proliferation assay was performed with CD4+ T cells collected from draining lymph nodes of the mice immunized with human interphotoreceptor retinoid-binding protein (hIRBP) peptide and co-cultured with iPS-SCs. Cytokine concentrations in the culture supernatant were examined. Mice were immunized with hIRBP peptide to induce EAU. The iPS-SCs were administered into the mice one day before the induction of EAU. The iPS-SCs decreased hIRBP-specific T cell proliferation depending on the number of cells. Productions of tumor necrosis factor-α and interferon-γ were significantly decreased; however, transforming growth factor-β1, nitric oxide, interleukin (IL)-13, IL-17A, and IL-17 F levels were elevated in the supernatant when the collected T cells were co-cultured with iPS-SCs. The iPS-SCs had immunosuppressant effects even without cell-to-cell contact, and their effects were non-specific to the antigen preloaded on iPS-SCs. EAU was significantly milder in the mice administered iPS-SCs prior to immunization. Macrophage-like iPS-SCs reduced Th1 immune response to a retinal antigen and Th1-mediated EAU in mice. These results showed the possibility of the application of iPS technology to the treatment of noninfectious ocular inflammation, endogenous uveitis, in the future.

In the core of NS, the density and pressure become so large that the nuclear matter possibly undergoes phase transition into a deconfined phase, consisting of quarks and gluons and their colour bound states. Even though the quark-gluon plasma has been observed in ultra-relativistic heavy-ion collisions\cite{Gyulassy, Andronic}, it is still unclear whether exotic quark matter exists inside neutron stars. Recent results from the combination of various perturbative theoretical calculations with astronomical observations\cite{Demorest, Antoniadis} shows that (exotic) quark matter could exist inside the cores of neutron stars above 2.0 solar masses ($M_{\odot}$)~\cite{Annala:2019puf}. We revisit the holographic model in Ref.~\cite{bch, bhp} and implement the equation of states~(EoS) of multiquark nuclear matter to interpolate the pQCD EoS in the high-density region with the nuclear EoS known at low densities. For sufficiently large energy density scale~($ε_{s}$) of the model, it is found that multiquark phase is thermodynamically prefered than the stiff nuclear matter above the transition points. The NS with holographic multiquark core could have masses in the range $1.96-2.23~(1.64-2.10) M_{\odot}$ and radii $14.3-11.8~(14.0-11.1)$ km for $ε_{s}=26~(28)$ GeV/fm$^{3}$ respectively. Effects of proton-baryon fractions are studied for certain type of baryonic EoS; larger proton fractions could reduce radius of the NS with multiquark core by less than a kilometer.

description: We developed a Landau type theory for the description of polar phenomena in low-dimensional transition metal dichalcogenides (TMDs), specifically exploring flexoelectric origin of the polarization induced by a spontaneous bending and by inversion symmetry breaking due to the interactions with substrate. We consider the appearance of the spontaneous out-of-plane polarization due to the flexoelectric coupling with the strain gradient of the spontaneous surface rippling and surface-induced piezoelectricity. Performed calculations proved that the out-of-plane spontaneous polarization, originated from flexoelectric effect in a rippled TMD, is bistable and reversible by a non-uniform electric field. In contrast, the spontaneous polarization induced by a misfit strain and symmetry-sensitive surface-induced piezoelectric coupling, cannot be reversed by an external electric field. The special attention is paid to the spectral analysis of the linear dielectric susceptibility and gain factor, which enhancement is critically important for the observation of the polar phenomena in low-dimensional TMDs by the surface-enhanced vibrational spectroscopy.

description: It is well known that a countable group admits a left-invariant total order if and only if it acts faithfully on R by orientation preserving homeomorphisms. Such group actions are special cases of group actions on simply connected 1-manifolds, or equivalently, actions on oriented order trees. We characterize a class of left-invariant partial orders on groups which yield such actions, and show conversely that groups acting on oriented order trees by order preserving homeomorphism admit such partial orders as long as there is an action with a point whose stabilizer is left-orderable.

description: Precise measurements of the geometrical thickness of a sample and its refractive index are important for materials science, engineering, and medical diagnosis. Among the possible non-contact evaluation methods, optical interferometric techniques possess the potential of providing superior resolution. However, in the optical frequency region, the ambiguity in the absolute phase-shift makes it difficult to measure these parameters of optically thick dispersive materials with sufficient resolution. Here, we demonstrate that dual frequency-comb spectroscopy can be used to precisely determine the absolute sample-induced phase-shift by analyzing the data smoothness. This method enables simultaneous determination of the geometrical thickness and the refractive index of a planar sample with a precision of five and a half digits and an ultra-wide dynamic range. The thickness and the refractive index at 193.414 THz of a silicon wafer determined by this method are 0.52047(3) mm and 3.4756(3), respectively, without any prior knowledge of the refractive index.

description: As part of the negotiating process for a post-Kyoto climate policy regime, several developing economies have announced carbon emission targets for 2020. China and India’s commitments are framed as emissions intensity reductions by 40 to 45 per cent and 20 to 25 per cent respectively between 2005 and 2020. But how feasible are these proposed emissions intensity reductions, and how do they compare with the targeted reductions in the United States and the European Union? In this research report we use a stochastic frontier model to explain the variation in countries’ energy intensities. We use the model to produce emissions projections for China and India under a number of scenarios that consider various rates of technological change and changes in the share of non-fossil energy. We find that China is likely to need to adopt ambitious carbon mitigation policies in order to achieve its stated target, and that its targeted reductions in emissions intensity are on par with those implicit in the United States and European Union targets. India’s target is less ambitious and might be met with only limited or even no dedicated mitigation policies.

description: Many recent advances in neural information retrieval models, which predict top-K items given a query, learn directly from a large training set of (query, item) pairs. However, they are often insufficient when there are many previously unseen (query, item) combinations, often referred to as the cold start problem. Furthermore, the search system can be biased towards items that are frequently shown to a query previously, also known as the 'rich get richer' (a.k.a. feedback loop) problem. In light of these problems, we observed that most online content platforms have both a search and a recommender system that, while having heterogeneous input spaces, can be connected through their common output item space and a shared semantic representation. In this paper, we propose a new Zero-Shot Heterogeneous Transfer Learning framework that transfers learned knowledge from the recommender system component to improve the search component of a content platform. First, it learns representations of items and their natural-language features by predicting (item, item) correlation graphs derived from the recommender system as an auxiliary task. Then, the learned representations are transferred to solve the target search retrieval task, performing query-to-item prediction without having seen any (query, item) pairs in training. We conduct online and offline experiments on one of the world's largest search and recommender systems from Google, and present the results and lessons learned. We demonstrate that the proposed approach can achieve high performance on offline search retrieval tasks, and more importantly, achieved significant improvements on relevance and user interactions over the highly-optimized production system in online experiments.

description: We describe how to reconstruct generalized scalar-tensor gravity (GSTG) theory, which admits exact solutions for physical type of the potentials. Our consideration deals with cosmological inflationary models based on GSTG with non-minimal coupling of a (non-canonical) scalar field to the Ricci scalar. The basis of proposed approach to the analysis of these models is a priori specified relation between the Hubble parameter $H$ and a function of non-minimal coupling $F=1+δF$ as $H\propto\sqrt{F}$. Deviations from Einstein gravity $δF$ induce a corresponding deviations of the potential $δV$ from a constant value and modify the dynamics from pure de Sitter exponential expansion. We analyze the models with exponential power-law evolution of the scale factor and we find the equations of influence of non-minimal coupling, choosing it in the special form, on the potential and kinetic energies. Such consideration allows us to substitute the physical potential into obtained equations and then to calculate the non-minimal coupling function and kinetic term that are define GSTG parameters. With this method, we reconstruct GSTG for polynomial, exponential, Higgs, Higgs-Starobinsky and Coleman-Weinberg potentials. Special attention we pay to parameters of cosmological perturbations and prove correspondence obtained solutions to observational data from Planck.

description: We report the discovery of a new transition type Wolf-Rayet (WR) WN/C star in the Galaxy. According to its coordinates (R.A., Dec)J2000 = 18h51m39.7s, -05d34m51.1s, and the distance (7.11 kpc away from Earth) inferred from the second Gaia, data release, it's found that WR 121-16 is located in the Far 3 kpc Arm, and it is 3.75 kpc away from the Galactic Center. The optical spectra obtained by the Large Sky Area Multi-Object Fiber Spectroscopic Telescope (LAMOST) and the 2.16 m telescope, both located at the Xinglong Observatory in China, indicate that this is a WR star of the transitional WN7o/WC subtype. A current stellar mass of about 7.1 M_solar, a mass-loss rate of M_dot = 10^(-4.97) M_solar/yr, a bolometric luminosity of log L/L_solar = 4.88, and a stellar temperature of T_* = 47 kK are derived, by fitting the observed spectrum with a specific Potsdam Wolf-Rayet (PoWR) model. The magnitude in V-band varies between 13.95 and 14.14 mag, while no period is found. Based on the optical spectra, the time domain data, and the indices of the astrometric solution of the Gaia data, WR 121-16 is likely a transitional WN/C single star rather than a WN+WC binary.
