description: This paper exploits a unique micro dataset that uses a natural field experiment to identify indirect effects of formal savings access on de facto ineligibles residing in the same community. Despite widespread interest in microfinance as a poverty-reduction tool, the indirect effects on the very poor of expanding formal financial services remain largely unexplored. This study examines evidence from a large field experiment which helps fill this gap. It also contributes to an important emerging literature on the indirect impacts of policy interventions in developing countries, often (incompletely) evaluated solely on the basis of how they impact participants and beneficiaries. In developing regions, households vulnerable to extreme poverty often benefit from long-standing local safety nets based on cash gifts and other transfers from relatives and friends, which help them smooth consumption across food-deficits and household shocks. To date, little is known about how these pre-existing practices are affected as community members begin adopting newly available formal financial services, and there remains much unexplored in the interaction of formal financial markets with informal safety nets. This paper addresses that gap by examining how formal savings expansion affects inter-household wealth transfers, with a particular emphasis on receipts by the most vulnerable. Using a rich panel dataset from Central Malawi that includes over 2,000 households, I find that experimentally boosting local savings uptake in rural areas leads to a strong positive effect on assistance receipts by non service-users during peak periods of hunger. The difference is strongest among the most vulnerable households. That is, the entrance of formal savings appears to complement local informal support systems for the highly vulnerable through an indirect mechanism, channeling greater wealth to such households during periods of food-deficits. The positive impacts of formal savings expansion on non service-users suggests that formal savings may have substantially greater benefits than would be suggested by focusing exclusively on the impacts experienced by the service-users themselves.

description: Algorithms to find optimal alignments among strings, or to find a parsimonious summary of a collection of strings, are well studied in a variety of contexts, addressing a wide range of interesting applications. In this paper, we consider chain letters, which contain a growing sequence of signatories added as the letter propagates. The unusual constellation of features exhibited by chain letters (one-ended growth, divergence, and mutation) make their propagation, and thus the corresponding reconstruction problem, both distinctive and rich. Here, inspired by these chain letters, we formally define the problem of computing an optimal summary of a set of diverging string sequences. From a collection of these sequences of names, with each sequence noisily corresponding to a branch of the unknown tree $T$ representing the letter's true dissemination, can we efficiently and accurately reconstruct a tree $T' \approx T$? In this paper, we give efficient exact algorithms for this summarization problem when the number of sequences is small; for larger sets of sequences, we prove hardness and provide an efficient heuristic algorithm. We evaluate this heuristic on synthetic data sets chosen to emulate real chain letters, showing that our algorithm is competitive with or better than previous approaches, and that it also comes close to finding the true trees in these synthetic datasets.

description: This study uses panel data from 1,142 Kenya smallholder households over four survey periods to examine the determinants of participation in land rental markets and to quantify the impact of renting land on households’ crop income and total income. We find that land rental markets in Kenya enhance productivity and are equitable. The results are consistent across different estimation methods and model specifications. Dynamic panel models were used to assess the impact of rental participation on households’ crop income and total income. After controlling for the endogeneity of rental market participation and the persistent effects of lagged income, we find that the decision to rent land increased tenant households’ net crop (net total) income by 25.1 (6.6) percent. These percentage gains are inversely related to household landholding size. Hence, land rental markets in Kenya appear to play an important role in raising incomes and reducing poverty for land-constrained smallholder farmers.

Complexity in patterns of racial segregation

Subjects: subject: Physics and Society (physics.soc-ph)
subject: FOS: Physical sciences

description: Cities are complex systems, their complexity manifests itself through fractality of their spatial structures and by power law distributions (scaling) of multiple urban attributes. Here we report on the previously unreported manifestation of urban complexity -- scaling in patterns of residential racial segregation. A high-resolution racial grid of a city is segmented into racial enclaves which are patches of stationary racial composition. Empirical PDFs of patch areas and population counts in 41 US cities were analyzed to reveal that these variables have distributions which are either power laws or approximate power laws. Power law holds for a pool of all patches, for patches from individual cities, and patches restricted to specific racial types. The average value of the exponent is 1.64/1.68 for area/population in 1990 and 1.70/1.74 in 2010. The values of exponents for type-specific patches vary, but variations had decreased from 1990 to 2010. We have also performed a multifractal analysis of patterns formed by racial patches and found that these patterns are monofractal with average values of fractal dimensions in the 0.94-1.81 range depending on racial types and the year of analysis. Power law distribution of racial patch sizes and a fractal character of racial patterns present observable and quantifiable constraints on models of racial segregation. We argue that growth by preferential attachment is a plausible mechanism leading to observed patterns of segregation.

description: Por que e sob quais condições a expansão dos plantios de soja para as áreas de cerrado em direção às áreas de mata da floresta Amazônica ocorreu com base em unidades de produção em larga escala? Esse problema traz duas reflexões, uma de ordem teórica, que trata das condições de possibilidades da produção capitalista em larga escala na agricultura, e outra de ordem prática, empírica, que trata das condições históricas que tornaram possível a construção de um modelo de produção agrícola com base na produção em larga escala. Neste trabalho serão analisadas as implicações dos processos de ocupação e colonização sobre a disponibilidade de terra. Não se trata de realizar uma análise do processo de colonização de terras do Brasil, mas de oferecer elementos auxiliares à compreensão da maneira pelas quais os mecanismos de acesso a terra favoreceram essa expansão das lavouras de soja.

description: We study the asymptotics related to the following matching criteria for two independent realizations of point processes X\sim X and Y\sim Y. Given l>0, X\cap [0,l) serves as a template. For each t>0, the matching score between the template and Y\cap [t,t+l) is a weighted sum of the Euclidean distances from y-t to the template over all y\in Y\cap [t,t+l). The template matching criteria are used in neuroscience to detect neural activity with certain patterns. We first consider W_l(θ), the waiting time until the matching score is above a given threshold θ. We show that whether the score is scalar- or vector-valued, (1/l)\log W_l(θ) converges almost surely to a constant whose explicit form is available, when X is a stationary ergodic process and Y is a homogeneous Poisson point process. Second, as l\to\infty, a strong approximation for -\log [\Pr{W_l(θ)=0}] by its rate function is established, and in the case where X is sufficiently mixing, the rates, after being centered and normalized by \sqrtl, satisfy a central limit theorem and almost sure invariance principle. The explicit form of the variance of the normal distribution is given for the case where X is a homogeneous Poisson process as well.

description: While the fishery production reaches its pick and runs to its decline, the aquaculture comes out as an alternative to reduce the pressure over the marine stock of fish. The coastal aquaculture led by the shrimp farming is rapidly expanding in the developing countries, and not less expressive are the initiatives to develop the rural aquaculture. Besides that the consolidation of the new paradigm of sustainable development, the aquaculture needs to be investigated regarding its sustainability. In this sense, having the systemic method as theoretical foundation, indicators are proposed to evaluate the sustainability of a project being carried out in the Castanhão reservoir, in Jaguaribara-CE, called Curupati-Peixe Project, that cultivates Nile Tilápia in net-ponds. The sustainability dimensions evaluated are economic-social, technological and environmental, that are considered here as subsystems. Theses indicators showed that the pisciculture project of Curupati-Peixe had a median level of sustainability, being the social dimension the one that contributed more to the observed performance.

description: Variational quantum circuits (VQCs) built upon noisy intermediate-scale quantum (NISQ) hardware, in conjunction with classical processing, constitute a promising architecture for quantum simulations, classical optimization, and machine learning. However, the required VQC depth to demonstrate a quantum advantage over classical schemes is beyond the reach of available NISQ devices. Supervised learning assisted by an entangled sensor network (SLAEN) is a distinct paradigm that harnesses VQCs trained by classical machine-learning algorithms to tailor multipartite entanglement shared by sensors for solving practically useful data-processing problems. Here, we report the first experimental demonstration of SLAEN and show an entanglement-enabled reduction in the error probability for classification of multidimensional radio-frequency signals. Our work paves a new route for quantum-enhanced data processing and its applications in the NISQ era.

Under the approximation, we define a new, light-path dependent angular diameter distance $\tilde{d}$ and show that it satisfies the optical scalar equation. The distance provides relations between quantities used in the gravitational lensing theory (the convergence-, the shear- and the twist-term) and those used in the scalar optics theory (the rates of expansion, shear and rotation).

description: In this work, model closures of the multiphase Reynolds-Average Navier-Stokes (RANS) equations are developed for homogeneous, fully-developed gas--particle flows. To date, the majority of RANS closures are based on extensions of single-phase turbulence models, which fail to capture complex two-phase flow dynamics across dilute and dense regimes, especially when two-way coupling between the phases is important. In the present study, particles settle under gravity in an unbounded viscous fluid. At sufficient mass loadings, interphase momentum exchange between the phases results in the spontaneous generation of particle clusters that sustain velocity fluctuations in the fluid. Data generated from Eulerian--Lagrangian simulations are used in a sparse regression method for model closure that ensures form invariance. Particular attention is paid to modelling the unclosed terms unique to the multiphase RANS equations (drag production, drag exchange, pressure strain and viscous dissipation). A minimal set of tensors is presented that serve as the basis for modelling. It is found that sparse regression identifies compact, algebraic models that are accurate across flow conditions and robust to sparse training data.

description: We study numerically the topological knot solution suggested recently in the Weinberg-Salam model. Applying the SU(2) gauge invariant Abelian projection we demonstrate that the restricted part of the Weinberg-Salam Lagrangian containing the interaction of the neutral boson with the Higgs scalar can be reduced to the Ginzburg-Landau model with the hidden SU(2) symmetry. The energy of the knot composed from the neutral boson and Higgs field has been evaluated by using the variational method with a modified Ward ansatz. The obtained numerical value is 39 Tev which provides the upper bound on the electroweak knot energy.

description: We define for quantum many-body systems a quasi-adiabatic continuation of quantum states. The continuation is valid when the Hamiltonian has a gap, or else has a sufficiently small low-energy density of states, and thus is away from a quantum phase transition. This continuation takes local operators into local operators, while approximately preserving the ground state expectation values. We apply this continuation to the problem of gauge theories coupled to matter, and propose a new distinction, perimeter law versus "zero law" to identify confinement. We also apply the continuation to local bosonic models with emergent gauge theories. We show that local gauge invariance is topological and cannot be broken by any local perturbations in the bosonic models in either continuous or discrete gauge groups. We show that the ground state degeneracy in emergent discrete gauge theories is a robust property of the bosonic model, and we argue that the robustness of local gauge invariance in the continuous case protects the gapless gauge boson.

description: Microbial biotransformation of argentatin A (1), isoargentatin A (2) and argentatin B (3), the cycloartane- and lanostane-type triterpenoid constituents of guayule (Parthenium argentatum) resin, with Cunninghamella elegans ATCC 9245-A0 afforded eight new metabolites 4–11. These were identified as products formed as a result of: (i) α- and β-hydroxylation at C-7 and C-11; (ii) sequential oxidation of these newly formed alcohols to their corresponding carbonyl analogues; and (iii) rearrangement of the 9(10)-cyclopropane ring. The observed regiospecific hydroxylation reactions are possibly catalyzed by cytochrome P450 enzymes known to be produced by C. elegans. It is interesting that among the biotransformation products 9–11 of argentatin B (3) with a carbonyl group at C-11, only 11 had resulted from the rearrangement of the 9(10)-cyclopropane ring under the conditions used for biotransformation. This constitutes the first report of biotransformation of argentatins by C. elegans.

description: Em 2004, o Acre possuía um Produto Interno Bruto (PIB) igual a R$ 3.241.847.000,00, com PIB per capita igual a R$ 5.143,00. Segundo dados do IBGE, os valores adicionados ao PIB na agropecuária, na indústria e no serviço, foram respectivamente de R$ 179.312.000,00; R$ 853.043.000,00 e R$ 1.999.670.000,00. Nesse contexto, torna-se relevante saber como as atividades econômicas impactam sobre a formação do PIB per capita nos municípios acreanos. Diante disso, a análise do impacto causado pela presença de unidades empresariais, pela pecuária e pela produção agrícola sobre o PIB per capita dos municípios possibilita uma visão da própria economia do estado. A teoria da externalidade é utilizada para referenciar esta pesquisa. Analiticamente, é utilizada a análise exploratória de dados espaciais. Os resultados mostram que em alguns municípios acreanos o PIB per capita é fortemente impactado pela pecuária e agricultura praticadas em seus vizinhos. Em relação à quantidade de unidades empresariais em um município, verificou-se que essa variável, neste modelo, não impacta sobre o PIB per capita nos municípios vizinhos contíguos. -------------------------------------------In 2004, the Acre had a Gross Domestic Product (GDP) equal to $ 3.241.847.000,00, with per capita GDP equal to $ 5.143,00.

In this context, it is important to know how the economic activities impact on the training of GDP per capita in the municipalities of Acre. Given that, the analysis of the impact caused by the presence of business units, the livestock and agricultural production on the GDP per capita of municipalities allows a vision of the economy of the state. The theory of externalities is used to refer this search. Analytically, is used exploratory analysis of spatial data. The results show that in some municipalities of Acre GDP per capita is strongly impacted by the livestock and agriculture practiced in its neighbours. In relation to the amount of business units in a municipality, it was found that this variable, in this model, no impact on GDP per capita in neighboring counties contiguous.

description: Synthesis of highly $^{13}$C isotope enriched azafullerene, C$_{59}$N embedded in C$_{60}$ is reported. $^{13}$C enriched fullerenes, produced with the Krätschmer-Huffmann process, were subject to a N$_{2}$ discharge that produces C$_{59}$N with a low probability. Raman spectroscopy indicates a homogeneous $^{13}$C distribution. Electron spin resonance measurement (ESR) proves that the C$_{59}$N concentration, 0.2 %, is similar as in non-enriched fullerenes. The ESR spectrum is simulated accurately with the known $^{14}$N and $^{13}$C hyperfine coupling constants. The material enables the nuclear spin-labelling of heterofullerene complexes with a potential for biological applications. It might also find applications as a building element for quantum computation.

Specifically, the goal is to determine the spatial relationship between outbreaks of fires in a given municipality and hospitalizations for respiratory morbidity in its neighbours contiguous. The results show that in some municipalities of Acre the hospitalizations caused by respiratory morbidity are the responsibility of its neighbours. Thus, it is clear that in the state of Acre as burned carry negative impacts on the quality of life, particularly on the health of society of Acre.

description: We present the prospects of searches for neutral, long-lived particles which decay to photons using their time of arrival measured with a newly installed timing system on the electromagnetic calorimeter (EMTiming) of the Collider Detector at Fermilab (CDF). A Monte Carlo simulation shows that EMTiming can provide separation between decay photons from particles with both a long lifetime and a low boost, and prompt photons from Standard Model backgrounds. Using a gauge mediated supersymmetry breaking (GMSB) $\tildeχ_{1}^{0}\toγ\tilde{G}$ model we estimate a quasi-model-independent sensitivity using only direct neutralino pair production, and also estimate the expected 95% confidence level exclusion regions for all superpartner production as a function of the neutralino mass and lifetime. We find that a combination of single photon and diphoton analyses should allow the Tevatron in run II to easily extend the exclusion regions from LEP II at high neutralino masses and lifetimes, and cover much, if not all, of the theoretically favored $m_{\tilde{G}}$ < 1 keV/c^2 parameter space for neutralino masses less than 150 GeV/c^2.

description: An arbitrary operator corresponding to a physical observable cannot be measured in a single measurement on currently available quantum hardware. To obtain the expectation value of the observable, one needs to partition its operator to measurable fragments. However, the observable and its fragments generally do not share any eigenstates, and thus the number of measurements needed to obtain the expectation value of the observable can grow rapidly even when the wavefunction prepared is close to an eigenstate of the observable. We provide a unified Lie algebraic framework for developing efficient measurement schemes for quantum observables, it is based on two elements: 1) embedding the observable operator in a Lie algebra and 2) transforming Lie algebra elements into those of a Cartan sub-algebra (CSA) using unitary operators. The CSA plays the central role because all its elements are mutually commutative and thus can be measured simultaneously. We illustrate the framework on measuring expectation values of Hamiltonians appearing in the Variational Quantum Eigensolver approach to quantum chemistry. The CSA approach puts many recently proposed methods for the measurement optimization within a single framework, and allows one not only to reduce the number of measurable fragments but also the total number of measurements.

description: L-Fuculokinases play a key role in both natural and synthetic metabolic pathways, not only for the utilization of L-fucose, but also for related monosaccharides, and catalyze selective phosphorylation of L-fuculose in the 1-position or of D-ribulose in the 5-position. Therefore, L-fuculokinases have been selected, the fucK gene from Escherichia coli K12 has been synthesized and cloned into an appropriate expression vector for the transformation of E. coli BL21(DE3). The cultivation of the transformed strain and the overexpression of the fucK gene has led to highly active L-fuculokinase after straightforward downstream processing. The soluble fraction from the crude cell extract could be directly applied in the enzymatic phosphorylation of L-fuculose. Recycling of the ATP cofactor was done with pyruvate kinase (PK) and the high energy phosphoenolpyruvate (PEP) as donor. The time course of the phosphorylation reactions has been monitored by 31P-NMR and 1H-NMR spectroscopy and L-fuculose could be phosphorylated with nearly 100% conversion. After standard workup, the L-fuculose-1-phosphate has been obtained in high yield and purity.

The Impact of Different Parameterizations on the Interpretation of CP Violation in Neutrino Oscillations

description: CP violation in the lepton mass matrix will be probed with good precision in upcoming experiments. The amount of CP violation present in oscillations can be quantified in numerous ways and is typically parameterized by the complex phase $δ_{\rm PDG}$ in the standard PDG definition of the lepton mixing matrix. There are additional parameterizations of the lepton mixing matrix as well. Through various examples, we explore how, given the current data, different parameterizations can lead to different conclusions when working with parameterization dependent variables, such as $δ$. We demonstrate how the smallness of $|U_{e3}|$ governs the scale of these results. We then demonstrate how $δ$ can be misleading and argue that the Jarlskog is the cleanest means of presenting the amount of CP violation in the lepton sector. We also confirm that, among the different parameterizations considered, the standard PDG parameterization has a number of convenient features.

description: We construct an Asplund Banach space $\mathcal{X}$ with a norming Markuševič basis such that $\mathcal{X}$ is not weakly compactly generated. This solves a long-standing open problem from the early nineties, originally due to Gilles Godefroy. En route to the proof, we construct a peculiar example of scattered compact space, that also solves a question due to Wiesław Kubiś and Arkady Leiderman.

description: We report on the XMM-Newton observation of HP Cet and Swift J0820.6-2805, two X-ray photon sources that are candidates to be members of the intermediate polar class of cataclysmic variables. If the historical optical light curve of HP Cet shows a periodic feature at $\simeq 96$ minutes, a clear identification of such a signature in the high energy band (apart for a variability on a time scale of $\simeq 8$ minutes as detected by the ROSAT satellite) is lacking. By using XMM-Newton archive data, we clearly identify a feature (at $\simeq 88$ minutes) which is marginally consistent with one of the binary system orbital periods reported in the literature. We also found a signature of a periodic features on the time scale of $\simeq 5.6$ minutes. In the case of Swift J0820.6-2805, the intermediate polar nature was previously unclear and the orbital and the white dwarf spin periods were unknown. Here, the 0.3-10 keV data undoubtedly reveal an orbital period and a white dwarf spin of $\simeq 87.5$ minutes and $\simeq 27.9$ minutes, respectively. The spectral analysis showed that both HP Cet and Swift J0820.6-280 are members of the under-luminous IP subclass since their luminosity in the $0.3-10$ keV band is estimated to be $\simeq 5\times 10^{30}$ erg s$^{-1}$ and $\simeq 3.8\times 10^{29}$ erg s$^{-1}$, respectively.

description: The release of bioactive peptides from proteins can be achieved by enzymatic hydrolysis, whereby mainly commercial enzymes are applied, although increasing attention is focused on alternative proteases. Hence, crude proteases from Bacillus sp. CL14, CL18, and CL33A were investigated to obtain antioxidant hydrolysates from bovine sodium caseinate (NaCAS) and soy protein isolate (SPI). The proteases were able to hydrolyze both substrates. Hydrolysis improved the radical-scavenging, Fe2+-chelating, and reducing power abilities of NaCAS and SPI. Higher antioxidant activities were commonly achieved at 2–3 h of hydrolysis. Overall antioxidant activities were higher for NaCAS hydrolysates produced with CL14 > CL18 > CL33 protease, and for SPI hydrolysates obtained with CL14 > CL33A ∼ CL18 protease. Generation of antioxidant protein hydrolysates suggest applications of enzymes and hydrolysates in food/feed (bio)technology.
