description: Survey propagation is a powerful technique from statistical physics that has been applied to solve the 3-SAT problem both in principle and in practice. We give, using only probability arguments, a common derivation of survey propagation, belief propagation and several interesting hybrid methods. We then present numerical experiments which use WSAT (a widely used random-walk based SAT solver) to quantify the complexity of the 3-SAT formulae as a function of their parameters, both as randomly generated and after simplification, guided by survey propagation. Some properties of WSAT which have not previously been reported make it an ideal tool for this purpose -- its mean cost is proportional to the number of variables in the formula (at a fixed ratio of clauses to variables) in the easy-SAT regime and slightly beyond, and its behavior in the hard-SAT regime appears to reflect the underlying structure of the solution space that has been predicted by replica symmetry-breaking arguments. An analysis of the tradeoffs between the various methods of search for satisfying assignments shows WSAT to be far more powerful that has been appreciated, and suggests some interesting new directions for practical algorithm development.

description: To efficiently manage serverless computing platforms, a key aspect is the auto-scaling of services, i.e., the set of computational resources allocated to a service adapts over time as a function of the traffic demand. The objective is to find a compromise between user-perceived performance and energy consumption. In this paper, we consider the \emph{scale-per-request} auto-scaling pattern and investigate how many function instances (or servers) should be spawned each time an \emph{unfortunate} job arrives, i.e., a job that finds all servers busy upon its arrival. We address this problem by following a stochastic optimization approach: we develop a stochastic gradient descent scheme of the Kiefer--Wolfowitz type that applies \emph{over a single run of the state evolution}. At each iteration, the proposed scheme computes an estimate of the number of servers to spawn each time an unfortunate job arrives to minimize some cost function. Under natural assumptions, we show that the sequence of estimates produced by our scheme is asymptotically optimal almost surely. In addition, we prove that its convergence rate is $O(n^{-2/3})$ where $n$ is the number of iterations.
 From a mathematical point of view, the stochastic optimization framework induced by auto-scaling exhibits non-standard aspects that we approach from a general point of view. We consider the setting where a controller can only get samples of the \emph{transient} -- rather than stationary -- behavior of the underlying stochastic system. To handle this difficulty, we develop arguments that exploit properties of the mixing time of the underlying Markov chain. By means of numerical simulations, we validate the proposed approach and quantify its gain with respect to common existing scale-up rules.

description: Stochastic reduced models are an important tool in climate systems whose many spatial and temporal scales cannot be fully discretized or underlying physics may not be fully accounted for. One form of reduced model, the linear inverse model (LIM), has been widely used for regional climate predictability studies - typically focusing more on tropical or mid-latitude studies. However, most LIM fitting techniques rely on point estimation techniques deriving from fluctuation-dissipation theory. In this methodological study we explore the use of Bayesian inference techniques for LIM parameter estimation of sea surface temperature (SST), to quantify the skillful decadal predictability of Bayesian LIM models at high latitudes. We show that Bayesian methods, when compared to traditional point estimation methods for LIM-type models, provide better calibrated probabilistic skill, while simultaneously providing better point estimates due to the regularization effect of the prior distribution in high-dimensional problems. We compare the effect of several priors, as well as maximum likelihood estimates, on (1) estimating parameter values on a perfect model experiment and (2) producing calibrated 1-year SST anomaly forecast distributions using a pre-industrial control run of the Community Earth System Model (CESM). Finally, we employ a host of probabilistic skill metrics to determine the extent to which a LIM can forecast SST anomalies at high latitudes. We find that the choice of prior distribution has an appreciable impact on estimation outcomes, and priors that emphasize physically relevant properties enhance the model's ability to capture variability of SST anomalies.

description: Η παρακάτω εργασία αναφέρεται στο μέγεθος του πληθυσμού και στη διαχείρισή του καθώς ο αριθμός των ανθρώπων που κατοικούν στη γη συνεχίζει να αυξάνεται. Λόγοι αυτής της αύξησης, η οποία είναι πιο εμφανής στις αστικές περιοχές είναι κυρίως η μείωση των ποσοστών θνησιμότητας, η αύξηση των γεννήσεων, των ιατρικών ανακαλύψεων και η αύξηση των μεταναστευτικών κυμάτων. Αυτό οδηγεί σε μια ποικιλία περιβαλλοντικών και κοινωνικών προβλημάτων, ενώ ταυτόχρονα προκύπτουν και αρνητικές οικονομικές συνέπειες. Στη συνέχεια παρουσιάζονται τα προβλήματα που δημιουργούνται εξαιτίας του υπερπληθυσμού, τα οποία μεταξύ άλλων είναι η εξάντληση των φυσικών πόρων, η αύξηση της ανεργίας, η μείωση του πληθυσμού των αγροτικών περιοχών και η ταχεία εξαφάνιση των ειδών. Προκύπτει ακόμα, ότι η αύξηση της αστικοποίησης σε συνδυασμό με την ένταση της ανθρώπινης δραστηριότητας είναι καταστροφικές για τη βιοποικιλότητα και την ψυχική υγεία των πολιτών. Ακολουθεί μια ανάλυση για κάθε ένα από τους 17 στόχους των Ηνωμένων Εθνών, τη σχέση τους με τον πληθυσμό και τη σύνδεση μεταξύ τους και γίνεται εμφανής η διαφορά των επιπτώσεων που δημιουργούνται σε διαφορετικές περιοχές του κόσμου. Τέλος προτείνονται λύσεις για τη διαχείριση του πληθυσμού οι οποίες είναι τόσο οι προσπάθειες των εθνικών θεσμικών οργάνων να εφαρμόσουν πολιτικές βάση κατευθυντήριων γραμμών, όσο και η παγκόσμια κοινότητα των πολιτών να δρα ατομικά προς το συμφέρον της ανθρωπότητας.

description: This paper examines the impact of agricultural research on poverty and welfare by conducting a systematic review of experimental and quasi-experimental impact evaluations of improved varieties disseminated by CGIAR between 2007 and 2015. The analysis focuses on the adoption of improved seeds, and specifically yield-increasing varieties, examining their direct causal impact from uptake on crop productivity gains, increased income and poverty reduction. The paper finds that agricultural research and improved varieties have been effectively contributing to productivity gains, however more efforts are needed to improve the evidence base to validate the positive impacts and encourage donors to invest in this area of agricultural research.

description: Dynamical quasi-localization of matter fields in extra dimension is an elegant mechanism to generate hierarchical 4-dimensional Yukawa couplings. We point out that a bulk matter field whose zero mode is quasi-localized can give a large Kaluza-Klein threshold correction to low energy gauge couplings, which is generically of the order of ln (Yukawa)/8pi^2, so it can significantly affect gauge coupling unification. We compute such threshold corrections in generic 5-dimensional theories compactified on S^1/Z_2 X Z_2, and apply the result to grand unified theories on orbifold generating small Yukawa couplings through quasi-localization.

Why Massive Black Holes are Small in Disk Galxies?

Year: 2003
Subjects: subject: Astrophysics (astro-ph)
subject: FOS: Physical sciences

description: A potential mechanism is proposed to account for the fact that supermassive black holes (SMBHs) in disk galaxies appear to be smaller than those in elliptical galaxies in the same luminosity range. We consider the formation of SMBHs by radiation drag (Poynting-Robertson effect), which extracts angular momentum from interstellar matter and thereby drives the mass accretion onto a galactic center. In particular, we quantitatively scrutinize the efficiency of radiation drag in a galaxy composed of bulge and disk, and elucidate the relation between the final mass of SMBH and the bulge-to-disk ratio of the galaxy. As a result, it is found that the BH-to-galaxy mass ratio, $M_{\rm BH}/M_{\rm galaxy}$, decreases with a smaller bulge-to-disk ratio, due to the effects of geometrical dilution and opacity, and is reduced maximally by two orders of magnitude, resulting in $M_{\rm BH}/M_{\rm galaxy}\approx 10^{-5}$. In contrast, if only the bulge components in galaxies are focused, the BH-to-bulge mass ratio becomes $M_{\rm BH}/M_{\rm bulge}\approx 10^{-3}$, which is similar to that found in elliptical galaxies. Thus, it turns out that the mass of SMBH primarily correlates with a bulge, not with a disk, consistently with observational data.

Our results show that the cross sections $σ_{tγ}(s)$ and $σ_{tz}(s)$ are very small at the $HERA$ collider with $\sqrt{s}=320GeV $. However, in most of the parameter space, $σ_{tγ}(s)$ or $σ_{tz}(s)$ is in the range of about $0.1pb \sim 1 pb$ at the $THERA$ collider with $\sqrt{s}=1000GeV$.

description: The Internet of Things (IoT) is an exploding market as well as a important focus area for research. Security is a major issue for IoT products and solutions, with several massive problems that are still commonplace in the field. In this paper, we have successfully minimized the risk of data eavesdropping and tampering over the network by securing these communications using the concept of tunneling. We have implemented this by connecting a router to the internet via a Virtual Private network while using PPTP and L2TP as the underlying protocols for the VPN and exploring their cost benefits, compatibility and most importantly, their feasibility. The main purpose of our paper is to try to secure IoT networks without adversely affecting the selling point of IoT.

description: Recent astrophysical observations indicate that the universe is composed of a large amount of dark energy (DE) responsible for an accelerated expansion of the universe, along with a sizeable amount of cold dark matter (CDM), responsible for structure formation. At present, the explanations for the origin or the nature of both CDM and DE seem to require ideas beyond the standard model of elementary particle interactions. Here, for the first time, we show that CDM and DE can arise entirely from the standard principles of strong interaction physics and quantum entanglement. Quantitative agreement with the present data obtains without the need for any adjustable parameters.

description: A collection of algorithms in object-oriented MATLAB is described for numerically computing with smooth functions defined on the unit ball in the Chebfun software. Functions are numerically and adaptively resolved to essentially machine precision by using a three-dimensional analogue of the double Fourier sphere method to form "ballfun" objects. Operations such as function evaluation, differentiation, integration, fast rotation by an Euler angle, and a Helmholtz solver are designed. Our algorithms are particularly efficient for vector calculus operations, and we describe how to compute the poloidal-toroidal and Helmholtz--Hodge decomposition of a vector field defined on the ball.

We construct its characters for the twisted and the untwisted sector and the diagonal partition function. We show that the degrees of freedom entering the partition function go to complete a Z_{m}-orbifold construction of the RCFT U(1)xSU(m)$ proposed for the Jain states. The resulting extended algebra of the chiral primary fields can be also viewed as a RCFT extension of the U(1)xW(m) minimal models. For m=2 we prove that our model, the TM, gives the RCFT closure of the extended minimal models U(1)xW(2).

description: Domain walls formed during a phase transition in a simple field theory model with $\mathbb{Z}_2$ symmetry in a periodic box have been demonstrated to annihilate as fast as causality allows and their area density scales $\propto t^{-1}$. We have performed numerical simulations of the dynamics of domain walls in the Two-Higgs Doublet Model (2HDM) where the potential has $\mathbb{Z}_2$ symmetry in two spatial dimensions. We observed significant differences with the standard case. Although the extreme long-time limit is the same for the $\approx 10^{5}$ sets of random initial configurations analysed, the percolation process is much slower due to the formation of long-lived loops. We suggest that this is due to the build up of superconducting currents on the walls which could lead ultimately to stationary configurations known as Kinky Vortons. We discuss the relevance of these findings for the production of Vortons in three spatial dimensions.

description: The influence of dark matter (DM) on the growth of supermassive black holes (SMBHs) in galaxies is studied. It is shown that gravitational scattering of DM particles on bulge stars leads to diffusion of DM in phase space {m, m_z, I} ('m' denotes the angular momentum and 'I' is the radial action). Appropriate diffusion coefficients are calculated for different bulge models, and it is argued that the diffusion along 'm' axis is the most important effect. It is shown that this process leads to noticeable flow of DM into the black hole (BH), resulting in its power-law growth: M_{bh} ~ t^{9/16}. Comparison with observational data shows that, in principle, this effect may explain observed masses of SMBHs. Special attention is paid to the corrections related to the innermost region of BH gravitational influence and the diffusion along 'I' axis. Their influence on the BH growth law is shown to be negligible in most cases.

description: To safeguard Civilian Global Navigation Satellite Systems (GNSS) external information available to the platform encompassing the GNSS receiver can be used to detect attacks. Cross-checking the GNSS-provided time against alternative multiple trusted time sources can lead to attack detection aiming at controlling the GNSS receiver time. Leveraging external, network-connected secure time providers and onboard clock references, we achieve detection even under fine-grained time attacks. We provide an extensive evaluation of our multi-layered defense against adversaries mounting attacks against the GNSS receiver along with controlling the network link. We implement adversaries spanning from simplistic spoofers to advanced ones synchronized with the GNSS constellation. We demonstrate attack detection is possible in all tested cases (sharp discontinuity, smooth take-over, and coordinated network manipulation) without changes to the structure of the GNSS receiver. Leveraging the diversity of the reference time sources, detection of take-over time push as low as 150us is possible. Smooth take-overs forcing variations as low as 30ns are also detected based on on-board precision oscillators. The method (and thus the evaluation) is largely agnostic to the satellite constellation and the attacker type, making time-based data validation of GNSS information compatible with existing receivers and readily deployable.

This study also tests and compares the degree of competition in three sub-periods, 2000-2004, 2004-2007 and 2008-2011. The results suggest that there is no evidence for the existence of oligopsony power in the time period from 2000 to 2011. However, the statistically significant parameters indicating market power was found for the period 2008-2011, which can be explained as a consequence of the government intervention on grain market.

description: Consumers in Benin developed strong preference to imported white rice. It is suggested that upgrading local rice value chain will require efforts on post-harvest segments by adding value to the product. Therefore, efforts have been deployed in the recent years to upgrade the value chain. Using experimental auction based on Becker-DegrootMarshack (BDM) mechanism combined with the endow-and-upgrade and a two stage approach, this study assessed: i) consumers’ willingness to upgrade and to pay for different parboiled rice types, ii) the competitiveness of local parboiled rice relative to imported parboiled and iii) the price premium of each improved processing technology. Results show that consumers will accept parboiled rice only if it is high quality rice. Among the local parboiled rice, the one produced with GEM parboiling technology, milled with rubber roll mill and sorted with optical sorter is more competitive than imported rice. Among technologies, optical sorter is the most important in the parboiled rice value chain upgrading. Econometric results revealed that rice attributes and information exchange on the benefit of parboiled rice are the most important to be considered in the value chain upgrading. Results suggest to combine improved processing technologies for an effective value chain upgrading.

description: In this study, we compare two of the most important models in the literature of estimating biofuels induced land use change (ILUC) emissions, GTAP-BIO and GLOBIOM. Since GTAP-BIO is publicly accessible while GLOBIOM currently is not, we use biofuel pathways from the results documented in the most recent GLOBIOM report and compare them using GTAP-BIO with the same specifications. Five EU biofuel pathways, including sugar beet ethanol, starchy crop ethanol, rapeseed oil biodiesel, soy oil biodiesel, and palm oil biodiesel, are tested. The results from GTAP-BIO show lower ILUC emissions for each of the five pathways. The gap in ILUC emission values between the two models is larger for vegetable oil biodiesel pathways than for sugar and starch ethanol pathways. Simulation results are compared to the extent GLOBIOM results were available in the documentation. The major drivers of differences in the two models are livestock rebound response, palm related issues (e.g., palm oil yield and peat oxidation factor), and foregone sequestration on abandoned land. The analysis shows that the strong livestock rebound effect, low palm oil yield, and high abandoned land foregone sequestration factor may lead to an overestimation of ILUC emissions in GLOBIOM.

description: In this study, we explore the effects of payments for environmental services on land use decisions among farmers living in Jambi province in Indonesia. Using a framed field experiment we compare land use decisions in a baseline with no payment with two alternative payments for environmental services (PES): an individual incentive scheme, where each participant receives a flat rate payment for each experimental land unit conserved, and a collective incentive scheme that offers individual payments only if an aggregate pre-determined conservation threshold is passed by the group. We find that individual and collective PES are equally effective on the average to increase environmentally friendly behavior associated with the cultivation of rubber agroforestry. Yet we find that whereas individual incentives work equally well for small and large farmers, collective incentives only work for large farmers. In addition, collective incentives generate an increase in conservation even at low payment levels whereas individual incentives only work when payments are high. Participants with a larger social network cultivating oil palm invest a lower share of their endowment in conservation. These findings highlight how land heterogeneity and social capital influence the success of a PES scheme.

description: Climate Change is an ever growing issue with a great importance due to wide socio-economic effects. Agriculture is the most climate sensitive economic sector that is influenced both positively and negatively by climate change. A change in temperature or precipitation could cause a significant change in crops productivity and yields. Different crop/bio-physical experts have been making efforts to process the impact of climate on crop yields through different crop modellings using input from different global climate models. In this research, the output of the crop models is used as a shock in the global computable general equilibrium economic model to evaluate the economic effects of climate change. Pakistan has two crop seasons – Kharif and Rabi- therefore two major crops i.e. Wheat and Rice have been chosen for this analysis. A Baseline scenario, representing business as usual with no change in climate, has been created using projections for GDP, population, factor supplies, and required food production. A counterfactual experiment has done using the same GDP and population growth as in the baseline but with addition of crop yield shocks from bio-physical models. A comparison of these two experiments has shown the economic effects of climate change by 2035.

description: Let $\D$ be the finite difference Laplacian associated to the lattice $\bZ^{d}$. For dimension $d\ge 3$, $a\ge 0$ and $L$ a sufficiently large positive dyadic integer, we prove that the integral kernel of the resolvent $G^{a}:=(a-\D)^{-1}$ can be decomposed as an infinite sum of positive semi-definite functions $ V_{n} $ of finite range, $ V_{n} (x-y) = 0$ for $|x-y|\ge O(L)^{n}$. Equivalently, the Gaussian process on the lattice with covariance $G^{a}$ admits a decomposition into independent Gaussian processes with finite range covariances. For $a=0$, $ V_{n} $ has a limiting scaling form $L^{-n(d-2)}Γ_{c,\ast}{\bigl (\frac{x-y}{L^{n}}\bigr)}$ as $n\to \infty$. As a corollary, such decompositions also exist for fractional powers $(-\D)^{-α/2}$, $0

description: Abstract

Affectively committed faculty are tremendous assets to their companies because they don't waver in the face of alluring outside opportunities. Thus, it's important to comprehend how various organisational elements raise employees' affective commitment. The purpose of the study was to look into how faculty commitment affected deemed universities and higher education institutions. While it is advised for higher education institutions to engage in a diverse workforce, more funds ought to be allocated to possibilities for professional development because these have an impact on affective commitment. The study subthemes that helped or hindered faculty work and learning fell within all of these categories. The psychological, social, cultural, and physical context in which learning takes place and influences faculty motivation and achievement is referred to as the learning environment.

description: The in silico design of peptides and proteins as binders is useful for diagnosis and therapeutics due to their low adverse effects and major specificity. To select the most promising candidates, a key matter is to understand their interactions with protein targets. In this work, we present PARCE, an open source Protocol for Amino acid Refinement through Computational Evolution that implements an advanced and promising method for the design of peptides and proteins. The protocol performs a random mutation in the binder sequence, then samples the bound conformations using molecular dynamics simulations, and evaluates the protein-protein interactions from multiple scoring. Finally, it accepts or rejects the mutation by applying a consensus criterion based on binding scores. The procedure is iterated with the aim to explore efficiently novel sequences with potential better affinities toward their targets. We also provide a tutorial for running and reproducing the methodology.
Incompleteness of trajectory-based interpretations of quantum mechanics

description: Trajectory-based approaches to quantum mechanics include the de Broglie-Bohm interpretation and Nelson's stochastic interpretation. It is shown that the usual route to establishing the validity of such interpretations, via a decomposition of the Schroedinger equation into a continuity equation and a modified Hamilton-Jacobi equation, fails for some quantum states. A very simple example is provided by a quantum particle in a box, described by a wavefunction initially uniform over the interior of the box. For this example there is no corresponding continuity or modified Hamilton-Jacobi equation, and the spacetime dependence of the wavefunction has a known fractal structure. Examples with finite average energies are also constructed.

description: The post-Minkowskian approach to gravitationally interacting binary systems ({\it i.e.}, perturbation theory in $G$, without assuming small velocities) is extended to the computation of the dynamical effects induced by the tidal deformations of two extended bodies, such as neutron stars. Our derivation applies general properties of perturbed actions to the effective field theory description of tidally interacting bodies. We compute several tidal invariants (notably the integrated quadrupolar and octupolar actions) at the first post-Minkowskian order. The corresponding contributions to the scattering angle are derived.

description: There is clear evidence of climate variability over a period of time in the developing countries and these countries are vulnerable to devastation caused by drought and floods. Analysis accompanied with robust results will create an opportunity to enhance the rural livelihoods that are prone to frequent climate shocks. We consider a southern state of India namely Karnataka, which belongs to a sub-tropical region facing a huge threat from climate change. In this article, we link agricultural production to climate variables to examine the impact of climatevariability on the crop yields. We follow a distinct approach using the nonlinear transformation of climatic variables to confirm climate damage on rice yields. The proposed econometric technique used in this paper is fixed effect panel regression model to identify the causal relationship between the yield and climate variables (rainfall and temperature). A panel of district wise cross section for a period of 1992-2013, with necessary inputs, is used in the model. The analysis in this paper is based on the smaller spatial scale (district wise) with updated climatic data emphasizing on Kharif season which helps to provide better insight on climate change effect and mitigation of climate-induced damages.

description: Studying the disappearance of superconductivity at the end of the overdoped region of the cuprate phase diagram offers a different approach for investigating the interaction which is responsible for pairing in these materials. In the underdoped region this question is complicated by the presence of charge and stripe ordered phases as well as the pseudogap. In the overdoped region the situation appears simpler with only a normal phase, a superconducting phase and impurity scattering. Here, for the overdoped region, we report the results of a combined dynamic cluster approximation (DCA) and a weak Born impurity scattering calculation for a $t-t'-U$ Hubbard model. We find that a decrease in the $d$-wave pairing strength of the two-particle scattering vertex is closely coupled to changes in the momentum and frequency structure of the magnetic spin fluctuations as the system is overdoped. Treating the impurity scattering within a disordered BCS $d$-wave approximation, we see how the combined effects of the decreasing $d$-wave pairing strength and weak impurity scattering lead to the end of the $T_c$ dome.
