description: We discuss the matching of the BPS part of the spectrum for (super)membrane, which gives the possibility of getting membrane's results via string calculations. In the small coupling limit of M--theory the entropy of the system coincides with the standard entropy of type IIB string theory (including the logarithmic correction term). The thermodynamic behavior at large coupling constant is computed by considering M--theory on a manifold with topology ${\mathbb T}^2\times{\mathbb R}^9$. We argue that the finite temperature partition functions (brane Laurent series for $p \neq 1$) associated with BPS $p-$brane spectrum can be analytically continued to well--defined functionals. It means that a finite temperature can be introduced in brane theory, which behaves like finite temperature field theory. In the limit $p \to 0$ (point particle limit) it gives rise to the standard behavior of thermodynamic quantities.

description: A theory of land market activity is developed for settings where there is uncertainty and private information about the security of land tenure. Land sellers match with buyers in a competitive search environment, and an illiquid land market emerges as a screening mechanism. As a consequence, adverse selection and an insecure system of property rights stifle land market transactions. The implications of the theory are tested using household level data from Indonesia. As predicted, formally titled land is more liquid than untitled land in the sense that ownership rights are more readily trans- ferable. Additional implications of the theory are verified empirically by constructing a proxy variable for land tenure security and studying the differences between markets for unregistered land across Indonesian provinces. Regional land market activity is appropriately linked to the distribution of the proxy variable.

description: Predicting the outcome of sales opportunities is a core part of successful business management. Conventionally, making this prediction has relied mostly on subjective human evaluations in the process of sales decision making. In this paper, we addressed the problem of forecasting the outcome of business to business (B2B) sales by proposing a thorough data-driven Machine Learning (ML) workflow on a cloud-based computing platform: Microsoft Azure Machine Learning Service (Azure ML). This workflow consists of two pipelines: (1) An ML pipeline to train probabilistic predictive models on the historical sales opportunities data. In this pipeline, data is enriched with an extensive feature enhancement step and then used to train an ensemble of ML classification models in parallel. (2) A prediction pipeline to utilize the trained ML model and infer the likelihood of winning new sales opportunities along with calculating optimal decision boundaries. The effectiveness of the proposed workflow was evaluated on a real sales dataset of a major global B2B consulting firm. Our results implied that decision-making based on the ML predictions is more accurate and brings a higher monetary value.
Dissipative Adiabatic Measurements: Beating the Quantum Cramér-Rao Bound

description: It is challenged only recently that the precision attainable in any measurement of a physical parameter is fundamentally limited by the quantum Cramér-Rao Bound (QCRB). Here, targeting at measuring parameters in strongly dissipative systems, we propose an innovative measurement scheme called {\it dissipative adiabatic measurement} and theoretically show that it can beat the QCRB. Unlike projective measurements, our measurement scheme, though consuming more time, does not collapse the measured state and, more importantly, yields the expectation value of an observable as its measurement outcome, which is directly connected to the parameter of interest. Such a direct connection {allows to extract} the value of the parameter from the measurement outcomes in a straightforward manner, with no fundamental limitation on precision in principle. Our findings not only provide a marked insight into quantum metrology but also are highly useful in dissipative quantum information processing.

description: While probabilistic models describe the dependence structure between observed variables, causal models go one step further: they predict, for example, how cognitive functions are affected by external interventions that perturb neuronal activity. In this review and perspective article, we introduce the concept of causality in the context of cognitive neuroscience and review existing methods for inferring causal relationships from data. Causal inference is an ambitious task that is particularly challenging in cognitive neuroscience. We discuss two difficulties in more detail: the scarcity of interventional data and the challenge of finding the right variables. We argue for distributional robustness as a guiding principle to tackle these problems. Robustness (or invariance) is a fundamental principle underlying causal methodology. A causal model of a target variable generalises across environments or subjects as long as these environments leave the causal mechanisms intact. Consequently, if a candidate model does not generalise, then either it does not consist of the target variable's causes or the underlying variables do not represent the correct granularity of the problem. In this sense, assessing generalisability may be useful when defining relevant variables and can be used to partially compensate for the lack of interventional data.

description: A model is proposed for the origin of cosmic rays (CRs) from ~10^14 eV to the highest energies, >10^20 eV. Gamma-Ray Bursts (GRBs) are assumed to inject CR protons and ions into the interstellar medium of star-forming galaxies--including the Milky Way--with a power law spectrum extending to a maximum energy ~10^20 eV. The CR spectrum near the knee is fit with CRs trapped in the Galactic halo that were accelerated and injected by an earlier Galactic GRB. These CRs diffuse in the disk and halo of the Galaxy due to gyroresonant pitch-angle scattering with MHD turbulence in the Galaxy's magnetic field. The preliminary (2001) KASCADE data through the knee of the CR spectrum are fit by a model with energy-dependent propagation of CR ions from a single Galactic GRB. Ultra-high energy CRs (UHECRs), with energies above the ankle are assumed to propagate rectilinearly with their spectrum modified by photo-pion, photo-pair, and expansion losses. We fit the measured UHECR spectrum assuming comoving luminosity densities of GRB sources consitent with possible star formation rate histories of the universe. For power-law CR proton injection p>2 this model implies that the nonthermal content in the GRB blast waves is hadronically dominated by a factor ~60-200. Calculations show that 100 TeV-100 PeV neutrinos could be detected several times per year from all GRBs in kilometer-scale neutrino detectors such as IceCube, for GRB blast-wave Doppler factors

description: Recent observations of massive pulsars having masses of the order of two solar mass pose a new challenge for compact objects such as hybrid stars and neutron stars. Extensions of the bag model and the Nambu-Jona-Lasino model have been used to model these stars to get higher mass stars. Quark matter has been predicted in the cores of these massive stars. In this work we show that an extension of the bag model, with a chemical potential dependent bag parameter can lead to an isentropic phase transition in the core of the neutron star. Our model shows that an EoS having all three quarks $u$, $d$ and $s$ would lead to massive stars with stable quark matter. We find that the mass of the stars not only depends on the bag constant but also on the mass of the strange quark. The mass - radius ratio which determines the redshift values on the surface, indicates that it is possible to obtain stable self bound strange quark matter stars with reasonable values of the bag pressure which correspond to the recent observations of large mass stars.

description: While a large body of literature documents the existence of informal arrangements to share risk across and within households, there has been little research on the various coping strategies through which risk sharing takes place, and how these strategies function. This study attempts to fill this gap in the literature and examine whether, and to what extent, individual labour-supply behaviour is one of such coping strategies used by households facing risk. Our hypothesis is that, as with a small business, individuals adjust their employment behaviour in the event that one of their household members experiences a variation in their labour supply, that is, either gains or loses a job. Using a unique dataset that collects employment histories for each family member in Tanzania, our results confirm our hypothesis and show that the labour supply of the household members is an important determinant of employment transitions, and that these effects are greater for women than for men. In the context of low-income countries, we interpret these findings as evidence that the household works as a risk-sharing institution built around women’s labour supply.

description: To keep up with increasing dataset sizes and model complexity, distributed training has become a necessity for large machine learning tasks. Parameter servers ease the implementation of distributed parameter management---a key concern in distributed training---, but can induce severe communication overhead. To reduce communication overhead, distributed machine learning algorithms use techniques to increase parameter access locality (PAL), achieving up to linear speed-ups. We found that existing parameter servers provide only limited support for PAL techniques, however, and therefore prevent efficient training. In this paper, we explore whether and to what extent PAL techniques can be supported, and whether such support is beneficial. We propose to integrate dynamic parameter allocation into parameter servers, describe an efficient implementation of such a parameter server called Lapse, and experimentally compare its performance to existing parameter servers across a number of machine learning tasks. We found that Lapse provides near-linear scaling and can be orders of magnitude faster than existing parameter servers.

description: The recent increase in farmland investments in developing countries by private equity funds, large multinationals and sometimes foreign governments has attracted widespread attention and strong emotions from various interest groups. A major criticism of such investments is how they often marginalise smallholder farmers, as it is often not part of the investment plans to engage with these farmers. There is, however, little empirical evidence to support such claims. Using evidence from three large-scale farmland investors in Zambia, this paper provides an in-depth analysis of different types of engagement dynamics and linkages between large-scale farmland investors and smallholder farmers, and employs the propensity score-matching method to estimate the impact of such engagement on the production outcomes of smallholder farmers. The results indicate that farmers who are deliberately engaged by investors perform better in terms of hybrid seed and fertiliser usage, and subsequently have a higher gross value per hectare of crops than those who are not.

description: It has been suggested recently that the microcanonical entropy of a system may be accurately reproduced by including a logarithmic correction to the canonical entropy. In this paper we test this claim both analytically and numerically by considering three simple thermodynamic models whose energy spectrum may be defined in terms of one quantum number only, as in a non-rotating black hole. The first two pertain to collections of noninteracting bosons, with logarithmic and power-law spectra. The last is an area ensemble for a black hole with equi-spaced area spectrum. In this case, the many-body degeneracy factor can be obtained analytically in a closed form. We also show that in this model, the leading term in the entropy is proportional to the horizon area A, and the next term is ln A with a negative coefficient.

Yielding, Rigidity, and Tensile Stress in Sheared Columns of Hexapod Granules

description: Granular packings of non-convex or elongated particles can form free-standing structures like walls or arches. For some particle shapes, such as staples, the rigidity arises from interlocking of pairs of particles, but the origins of rigidity for non-interlocking particles remains unclear. We report on experiments and numerical simulations of sheared columns of "hexapods," particles consisting of three mutually orthogonal sphero-cylinders whose centers coincide. We vary the length-to-diameter aspect ratio, $α$, of the sphero-cylinders and subject the packings to quasistatic direct shear. For small $α$, we observe a finite yield stress. For large $α$, however, the column becomes rigid when sheared, supporting stresses that increase sharply with increasing strain. Analysis of X-ray micro-computed tomography (Micro-CT) data collected during the shear reveals that the stiffening is associated with a tilted, oblate cluster of hexapods near the nominal shear plane in which particle deformation and average contact number both increase. Simulation results show that the particles are collectively under tension along one direction even though they do not interlock pairwise. These tensions comes from contact forces carrying large torques, and they are perpendicular to the compressive stresses in the packing. They counteract the tendency to dilate, thus stabilize the particle cluster.

description: The extreme-gravity collisions between black holes allow us to probe the underlying theory of gravity. We apply the theory-agnostic inspiral-merger-ringdown consistency test to an example theory beyond general relativity for the first time. Here we focus on the string-inspired Einstein-dilaton Gauss-Bonnet gravity and modify the inspiral, ringdown, and remnant black hole properties of the gravitational waveform. We found that future multiband observations allow us to constrain the theory stronger than current observations by an order of magnitude. The formalism developed here can easily be applied to other theories.

Despite the existence of new technologies, levels of agricultural productivity remain low, and lower than those of other developing regions. A number of factors, including constraints on the adoption of new technologies, could explain this low productivity. Indeed, the adoption of new technologies in agriculture in Sub-Saharan Africa is influenced by several factors, including the socio-economic characteristics of households, the mode of operation and management of production, market practices, processing characteristics, and the degree of awareness and social networks. It is essential to consider these factors if new programmes and projects for introducing and disseminating new technologies are to be successful. This would help increase productivity, and thereby reduce poverty and food insecurity across the continent.

Yet the impacts of excessive market-access costs for farmers has not been sufficiently analysed, particularly in sub-Saharan Africa (SSA). Using the newly available FAO/MAFAP dataset, we augment the GTAP model with domestic support and border protection, as well as data on market development gaps (MDGs) in selected SSA countries. We undertake several policy simulations to explore the impacts of changes in excessively high marketing costs. Our findings indicate that addressing MDGs can bring positive overall benefits, with particularly strong gains accruing to sectors and countries with very negative MDGs, such as the non-traditional crops in Ethiopia. In other cases, reducing positive MDGs, which operate as protection of certain sectors from imports, is projected to lead to a decline in exports and output, such as in the case of Ethiopian oilseeds.

description: We study the evolution of stable D-branes of C/Z_n and twisted circle theories in the process of closed string tachyon condensation. We interpret the fractional branes in these backgrounds as type II branes wrapping (`blown up') cycles, and trace the evolution of the corresponding cycles under tachyon condensation. We also study RG flows of the corresponding N=2 boundary conformal field theories. We find flows along which fractional D-branes either disappear or evolve into other fractional D-branes, and other flows along which bulk branes either disappear or evolve into stable branes.

description: Using a non-experimental cross-sectional dataset of 471 households, we evaluate the impacts of satellite collection points (SCPs) under the Purchase for Progress (P4P) initiative implemented by the World Food Programme (WFP) on storage decisions and crop income from maize sales among smallholder farmers in Uganda. We find strong evidence that storage users had significantly more maize sales due to significantly larger inventories and received higher maize prices than the nonstorage users. This evidence is robust across the two econometric estimators, consisting of the ordinary least squares (OLS) and two-stage instrumental variable approaches. These results demonstrate that the SCPs are successful in linking farmers to markets and result in improved welfare of the users, suggesting that they should be scaled up and scaled out as a poverty-reducing development intervention and strategy in rural areas with storable agricultural products.

description: In this paper we provide a new method to certify that a nearby polynomial system has a singular isolated root with a prescribed multiplicity structure. More precisely, given a polynomial system f $=(f\_1, \ldots, f\_N)\in C[x\_1, \ldots, x\_n]^N$, we present a Newton iteration on an extended deflated system that locally converges, under regularity conditions, to a small deformation of $f$ such that this deformed system has an exact singular root. The iteration simultaneously converges to the coordinates of the singular root and the coefficients of the so called inverse system that describes the multiplicity structure at the root. We use $$α$$-theory test to certify the quadratic convergence, and togive bounds on the size of the deformation and on the approximation error. The approach relies on an analysis of the punctual Hilbert scheme, for which we provide a new description. We show in particular that some of its strata can be rationally parametrized and exploit these parametrizations in the certification. We show in numerical experimentation how the approximate inverse system can be computed as a starting point of the Newton iterations and the fast numerical convergence to the singular root with its multiplicity structure, certified by our criteria.

description: The entropy of an ergodic finite-alphabet process can be computed from a single typical sample path x_1^n using the entropy of the k-block empirical probability and letting k grow with $n$ roughly like log n. We further assume that the distribution of the process is a g-measure; g-measures form a large class of Gibbs measures. We prove large deviation principles for conditional, non-conditional and relative k(n)-block empirical entropies.

description: Smallholder rural farmers are exposed to diverse idiosyncratic and covariate shocks that lead to high income and consumption volatility. Formal cash management tools, which are important for managing risk and volatility, often break down due to high information asymmetries and the transaction costs of operating in rural areas. Given this, community-based cash management tools have continued to be a dominant means of managing risk in rural areas. Community-based cash management tools can be home grown or externally induced, e.g. NGO-initiated savings groups. This study finds that participation in such savings groups significantly expands access to the financial resources that can be used to purchase goods and services, as well as to the social networks that are needed to support smallholder farmer livelihoods. However, the impact on access to physical and natural capital (at least in the short to medium term) is not significant, thus calling for complementary development interventions to reduce smallholder farmers’ vulnerability.

description: In this paper we present a multiresolution-based method for period determination that is able to deal with unevenly sampled data. This method allows us to detect superimposed periodic signals with lower signal-to-noise ratios than in classical methods. This multiresolution-based method is a generalization of the wavelet-based method for period detection that is unable to deal with unevenly sampled data, presented by the authors in Otazu et al. (2002). This new method is a useful tool for the analysis of real data and, in particular, for the analysis of astronomical data.

subject: per capita GDP and Real per capita public health expenditure

description: This paper identifies some major drivers of per capita public health expenditure growth in Tanzania using nationally representative annual data between 1995 and 2014. It used Bayesian model based on Markov Chain Monte Carlo (MCMC) simulation. The empirical result shows that both the real GDP per capita and population age 65 years and older exert a positive effect on per capita public health expenditure growth in Tanzania. Advances in medical technologies represented by life expectancy seem to reduce real per capita public health expenditure growth in Tanzania. However, the credible intervals for life expectancy and population age 65 years and older are very wide suggesting a lot of uncertainty with these estimates. The results imply that, future trends in per capita public health spending would mainly depend on the development of the economy such as real per capita gross domestic product. The result suggests the rapid growth in real per capita public health expenditure is likely to continue in future when the country economy becomes more robust and increase of population age 65 years and above.

description: This study examines the mediating effect of institutions on the relationship between natural resources and FDI inflows using the panel data of 46 Sub-Saharan Africa countries over 2000- 2015. The panel unit root tests by Im, Pesaran and Shin and Fisher type are employed and results indicate that data are stationary at first difference whereas the Pedroni cointegration tests confirm for the long-run relationship among variables. The GMM estimator is employed to account for the endogenous problems. The initial results demonstrate that FDI-Resources curse exists because natural resources crowd out non-natural resource sectors. Moreover, significant positive relationship between FDI and the interaction variable of institutions and natural resources signify that FDI-Resources curse exist in countries with weak institutions. The findings of this study are important in Sub-Saharan Africa because they enforce institutions and governance to promote sectoral linkages and build economy diversity towards the agenda 2063, “The Africa We Want”.
